In the realm of Wood Sanding Machine, enterprises have been long beset by a multitude of problems. Regarding talent, the manufacturing industry lags behind in the talent race against the Internet industry. Additionally, the severe dust pollution in sanding and sanding workshops makes it not only arduous to attract talents but also a great challenge to retain them. Meanwhile, with limited profitability, enterprises have to grapple with the rising salary expenditures year by year, and the cost of human resources continues to soar. From a technological perspective, water - based paint wooden doors are extremely prone to being sanded through during the sanding process. Solid wood raw materials are often scrapped due to improper sanding operations. Carved wooden doors are easily damaged during sanding, and the low - productivity manual sanding method fails to meet production needs. It is extremely difficult to achieve uniform sanding for special - shaped wooden doors, especially when dealing with concave and convex surfaces, which has become a major technical challenge. The sanding effect of hollow - out wooden doors is far from satisfactory, with the processing of edge and corner lines lacking smoothness.
Market demands are also constantly evolving. Users have increasingly stringent requirements for the quality of wooden doors. Designers' works are becoming more artistic, and the number of personalized customization orders is on the rise. These problems and changes have made it urgent for wooden door sanding enterprises to obtain an efficient piece of equipment to break through the bottleneck. Against this backdrop, the Sandwell special - shaped sanding and blasting machine emerged.
The key feature of the Sandwell special - shaped blast-sanding machine lies in "spraying". Its principle is to use compressed air as power to spray abrasives onto the surface of the workpiece at a certain speed. Through the impact and sanding of the abrasives on the workpiece surface, the purpose of sanding is achieved. Its most significant advantage is the ability to achieve "uniform and all - around sanding without dead angles".
Thanks to the "all - pervasive" nature of air and abrasives with appropriate fineness, any grooves and inner corners can be evenly ground, effectively avoiding the problem of missed sanding. Since the sanding is uniform, there will be no situation where some parts are not sanded properly while some parts are sanded through due to uneven sanding force. The special - shaped sanding and blasting machine can complete multi - angle sanding for the primer sanding of various solid wood doors, solid wood carved doors, solid wood inlaid doors, etc. at one time, and basically does not require manual re - sanding.
Features of the Sandwell Special - shaped Blast-sanding Machine
Dual sand and dust separation system
The separation 1 system is primarily tasked with separating the dust from the recycled sand - dust mixture.
The separation 2 system is mainly responsible for isolating the reusable sand grains from the sand - dust mixture retrieved by the dust - collection system.
These two sets of sand - dust separation systems can maximize the separation and recycling of effective sand grains. During the sanding process, a portion of the abrasives will transform into dust due to impact and sanding. The dust - sand separation system utilizes negative pressure to recycle the dust, achieving a recovery rate of up to 99%. As the dust is being recycled, the abrasives, under the influence of gravity, fall into the sand storage tank. The abrasive recycling system then recycles and reuses them, which not only boosts the utilization rate but also cuts down on material costs.
Dual Auger System
Two sets of auger sand - dust conveying systems are employed to ensure that the sand dust can be more efficiently delivered to the separation system.
Independent Spray Gun Control and Adjustment System
This system guarantees a perfect match between the spray gun and the workpiece.
High - Efficiency Plate Surface Dust - Removal System
Comprising 3 air knives, 2 cleaning rollers, and an independently liftable and lowerable material - pressing system, in coordination with an independent air - flow operation cavity, it attains an excellent dust - removal effect.
Intelligent Air - Saving System
Through the feeding induction system, the spray gun is automatically controlled to switch on and off, thereby saving air and sand amounts.
Intelligent Adjustment System
Equipped with a PLC, touch - screen human - machine interface, and frequency - converter control system, it enables precise control and can store a vast number of sanding parameters for easy access at any time, realizing one - click machine adjustment. The setting can be accomplished through simple parameter input.
When it comes to cost, this is precisely where the Sandwell special - shaped blast-sanding machine demonstrates its superiority. Firstly, the abrasive consumption of the Sandwell special - shaped blast-sanding machine is extremely low, effectively reducing the abrasive cost. Thanks to its all - around and high - quality sanding effect, the use of labor is significantly reduced, leading to a substantial decrease in labor costs. The enhanced efficiency of the sanding process lessens the idle production capacity of other processes, improves the overall efficiency and production capacity, and reduces the unit - time and product costs. With no issues of missed sanding or sanding through, it increases the yield rate and the quality of the finished product, reduces the average cost of the finished product, enhances the product cost - performance ratio, and strengthens the market competitiveness. Moreover, the price of the Sandwell special - shaped blast-sanding machine is on a par with that of traditional sanding machinery. It should be noted that the application scope of the Sandwell special - shaped blast-sanding machine is not restricted to wooden doors; door frames, moldings, etc. can also be sanded using this machine.
