Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sanding machine technology, and in particular relates to a collection structure for sanding machines. Background Technology
[0002] A sander is a type of mechanical equipment widely used for surface processing of materials such as wood, engineered wood, metal, and plastic. Its main function is to grind, polish, deburr, remove rust, and clean oxide layers or coatings on the surface of workpieces by using a high-speed rotating sanding belt or grinding wheel to improve surface smoothness, gloss, and remove surface defects.
[0003] Existing sanders require a mechanism to clean and collect debris from the sanding belt surface. The problem with the aforementioned technology is that during long-term operation, the sanding belt surface of existing sanders easily accumulates a large amount of debris, dust, and resinous substances due to grinding operations. If not cleaned in time, this can not only cause blockage of the sanding belt surface, reducing its cutting efficiency and processing quality, but also accelerate sanding belt wear, shorten its service life, and even affect the surface treatment effect of subsequent workpieces. However, most sanders currently lack effective sanding belt surface cleaning and debris collection devices in their structural design, resulting in increased cleaning frequency, higher manual maintenance costs, and dust pollution problems, affecting the safety of the working environment and the stability of the equipment. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a collection structure for sanders that can overcome the above problems or at least partially solve the above problems.
[0005] This utility model is implemented as follows: a collection structure for a sander includes a sander, a sanding belt and a servo motor. The sanding belt is sleeved on the surface of the sander, the servo motor is located at the lower end of the sander, a collection mechanism is provided on the surface of the servo motor, and an auxiliary mechanism is provided below the collection mechanism.
[0006] The collection mechanism is used to clean and collect debris from the surface of the sanding belt;
[0007] The auxiliary mechanism is used to store the debris.
[0008] To improve the cleaning effect, preferably, the collection mechanism includes a collection hopper, a cleaning roller, a transmission component, a reciprocating screw, a cleaning block, and a guide rod. The inside of the collection hopper is rotatably connected to the two end surfaces of the cleaning roller. The left end of the cleaning roller is drivenly connected to the inner surface of the transmission component. The two ends of the transmission component are drivenly connected to the left end surfaces of the two reciprocating screws. The surface of the reciprocating screw is threadedly connected to the inner wall of the cleaning block. The upper side of the inner wall of the cleaning block is slidably connected to the surface of the guide rod. The surface of the cleaning roller is equipped with a brush, which can continuously clean the surface of the sanding belt during rotation, effectively removing debris, dust, and resin deposits generated by grinding operations, preventing clogging of the sanding belt surface, and thus maintaining its good cutting ability.
[0009] To improve the efficiency of debris collection, the auxiliary mechanism preferably includes a storage box, a limiting block, a pressing rod, a stop rod, and a support block. The inner walls at both ends of the storage box are in contact with the surface of the limiting block, the outer surface of the limiting block is in contact with the lower surface of the pressing rod, the inner wall of the pressing rod is slidably connected to the surfaces of the two stop rods through a sliding groove, and the upper surface of the stop rod is in contact with the lower surface of the support block. The storage box is used to receive grinding debris, dust, and other impurities falling through the collection hopper, thereby achieving centralized collection of waste generated during processing, thus avoiding environmental pollution and facilitating subsequent cleaning and maintenance.
[0010] To improve the stability of the reciprocating screw rotation, preferably, a tensioning wheel is provided at the left end of the collecting hopper, and the surface of the tensioning wheel is fixedly connected to the surface of the collecting hopper. Elastic blocks are provided on the inner wall of the pressing rod and the lower end of the limiting block. By setting the tensioning wheel, the transmission component that drives the reciprocating screw rotation can be effectively tensioned, ensuring that the power output of the servo motor is transmitted to the reciprocating screw through the transmission component and that a stable transmission ratio and sufficient friction are maintained. This prevents problems such as slippage, reduced transmission efficiency, or unstable operation caused by a loose transmission belt.
[0011] To improve the smoothness of the reciprocating screw operation, preferably, the two side surfaces of the collecting hopper are fixedly connected to the surface of the sander, the output end of the servo motor is fixedly connected to the right end of the cleaning roller, both ends of the reciprocating screw are rotatably connected to the inner wall of the collecting hopper, and both ends of the guide rod are fixedly connected to the inner wall of the collecting hopper. The reciprocating screw can rotate stably inside the collecting hopper without axial movement, improving the coaxiality and stability of the reciprocating screw operation, extending its service life, and providing reliable power support for the reciprocating motion of the cleaning block.
[0012] To improve ease of operation, preferably, the lower end of the collecting hopper contacts the surface of the storage box, the surface of the limiting block is slidably connected to the interior of the lower end of the collecting hopper via a sliding groove, the surface of the pressing rod is slidably connected to the two side surfaces of the collecting hopper, the opposite side surfaces of the two stop rods are fixedly connected to both ends of the elastic block, the surfaces of the two support blocks are fixedly connected to the two side surfaces of the collecting hopper, and the lower end of the limiting block is fixedly connected to the surface of the elastic block. The elastic block maintains a stable assembly relationship of the stop rod inside the pressing rod, and the restoring force of the elastic block enables an automatic pop-out function. When the stop rod is pressed, it can retract; when released, it automatically resets and contacts the lower surface of the support block, thereby locking the position of the pressing rod.
[0013] To improve the comprehensiveness of cleaning, preferably, the surface of the tensioning wheel is slidably connected to the surface of the transmission component, the surface of the servo motor is fixedly connected to the surface of the collection hopper, the surface of the cleaning roller is slidably connected to the surface of the sanding belt, and the upper surface of the cleaning block is slidably connected to the surface of the sanding belt. Driven by the reciprocating screw, the cleaning block reciprocates along the width direction of the sanding belt, enabling it to perform lateral coverage cleaning of the sanding belt surface and reduce the cleaning blind spots caused by traditional single-direction cleaning.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention comprises a collection mechanism, an auxiliary mechanism, a cleaning roller, a reciprocating screw, a cleaning block, a guide rod, a storage box, a limit block, a stop rod, and a support block. The collection mechanism is used to clean and collect debris from the surface of the sanding belt. The auxiliary mechanism is used to store the debris. The cleaning roller is equipped with a brush that continuously cleans the surface of the sanding belt during rotation, effectively removing debris, dust, and resin deposits generated during grinding operations, preventing clogging of the sanding belt surface, and maintaining its good cutting ability. The storage box is used to collect grinding debris, dust, and other impurities falling through the collection hopper, realizing centralized collection of waste generated during processing, thereby avoiding environmental pollution and facilitating subsequent cleaning and maintenance. This invention solves the problem that after sanding machines have been running for a long time, debris, dust, and resin easily accumulate on the surface of the sanding belt. Failure to clean them will reduce efficiency and quality, accelerate wear, shorten lifespan, and affect the surface treatment of workpieces. Currently, most sanding machines lack effective cleaning and debris collection devices, resulting in frequent cleaning, high maintenance costs, and potential dust pollution, affecting the working environment and equipment stability.

[0023] like Figures 1 to 4As shown in the figure, the present invention provides a collection structure for a sander 5, including a sander 5, a sanding belt 6, and a servo motor 7. The sanding belt 6 is sleeved on the surface of the sander 5, and the servo motor 7 is located at the lower end of the sander 5.

The collection mechanism 1 includes a collection hopper 101, a cleaning roller 102, a transmission component 103, a reciprocating screw 104, a cleaning block 105, and a guide rod 106. The inside of the collection hopper 101 is rotatably connected to the two ends of the cleaning roller 102. The left end of the cleaning roller 102 is drively connected to the inner surface of the transmission component 103. The two ends of the transmission component 103 are connected to two reciprocating screws 104. The left end of the reciprocating lead screw 104 is connected to the drive mechanism. The surface of the reciprocating lead screw 104 is threaded to the inner wall of the cleaning block 105. The upper side of the inner wall of the cleaning block 105 is slidably connected to the surface of the guide rod 106. The surface of the cleaning roller 102 is equipped with a brush, which can continuously clean the surface of the sanding belt 6 during rotation, effectively removing debris, dust, and resin deposits generated by grinding operations, preventing clogging of the sanding belt 6, and thus maintaining its good cutting ability.

The surfaces are slidably connected via a groove. The upper surface of the stop rod 204 contacts the lower surface of the support block 205. The storage box 201 is used to receive grinding debris, dust, and other impurities falling from the collection bucket 101, realizing the centralized collection of waste generated during the processing, thereby avoiding environmental pollution and facilitating subsequent cleaning and maintenance. A tensioning wheel 3 is provided at the left end of the collection bucket 101, and the surface of the tensioning wheel 3 is fixedly connected to the surface of the collection bucket 101. Elastic blocks 4 are provided on the inner wall of the pressing rod 203 and the lower end of the limiting block 202. By setting the tensioning wheel 3, the transmission component 103 that drives the reciprocating screw can be effectively tensioned, ensuring that the power output of the servo motor 7 is transmitted to the reciprocating screw through the transmission component 103, maintaining a stable transmission ratio and sufficient friction, preventing... To address issues such as slippage, reduced transmission efficiency, or unstable operation caused by a loose transmission belt, the surfaces of the collection hopper 101 are fixedly connected to the surface of the sander 5. The output end of the servo motor 7 is fixedly connected to the right end of the cleaning roller 102. The two ends of the reciprocating screw 104 are rotatably connected to the inner wall of the collection hopper 101, and the two ends of the guide rod 106 are fixedly connected to the inner wall of the collection hopper 101. The reciprocating screw 104 can rotate stably inside the collection hopper 101 without axial movement, improving the coaxiality and stability of the reciprocating screw 104, extending its service life, and providing reliable power support for the reciprocating motion of the cleaning block 105.

The surface of the servo motor 7 is fixedly connected to the surface of the collecting hopper 101. The surface of the cleaning roller 102 is slidably connected to the surface of the sanding belt 6. The upper surface of the cleaning block 105 is slidably connected to the surface of the sanding belt 6. Driven by the reciprocating screw 104, the cleaning block 105 reciprocates along the width direction of the sanding belt 6, enabling it to perform lateral coverage cleaning of the surface of the sanding belt 6, reducing the cleaning blind spots caused by traditional unidirectional cleaning.
[0024] The working principle of this utility model:
[0025] During the use of the sander 5, the surface of the sanding belt 6 may become clogged due to debris, dust, and resin residue generated during grinding, leading to a decrease in its cutting performance. To ensure the working efficiency and service life of the sanding belt 6, a debris collection mechanism 1 is installed below the sanding belt 6. This collection mechanism 1 includes a collection hopper 101 located at the bottom of the sanding belt 6, on which a servo motor 7 is mounted. Simultaneously with the operation of the sander 5, the servo motor 7 starts synchronously, and its output drives the cleaning roller 102 to rotate. The rotation direction of the cleaning roller 102 is opposite to the running direction of the sanding belt 6, and they operate synchronously. The surface of the cleaning roller 102 is equipped with a brush that can remove dust and resin residue during rotation. During the process, the surface of the sanding belt 6 is continuously cleaned to effectively remove attached dust and debris, thereby maintaining the good cutting ability of the sanding belt 6. A transmission component 103 is provided at the left end of the cleaning roller 102 and is connected to the reciprocating screws 104 on both sides. When the servo motor 7 drives the cleaning roller 102 to rotate, it also drives the reciprocating screws 104 to rotate. A cleaning block 105 is threaded onto the reciprocating screw 104. As the screw rotates, the cleaning block 105 can perform reciprocating linear motion on its surface. This motion allows the cleaning block 105 to move back and forth along the width direction of the sanding belt 6 to further clean the surface of the sanding belt 6. The removed debris is collected in the collection hopper 101. The debris falls into the storage box 201 below for centralized collection. To facilitate regular cleaning of the debris inside the storage box 201, when it is necessary to remove the storage box 201, the operator first pinches the stop bar 204 on the pressing rod 203 and presses it inward to retract it into the stop bar 204. Then, the stop bar 204 is pulled upward along the inner wall of the support block 205. At this time, the limiting block 202 at the lower end of the pressing rod 203 moves outward under the action of the elastic element, disengaging from the inner wall of the storage box 201. After completing the same operation on the auxiliary mechanisms 2 on both sides of the storage box 201, it can be smoothly pulled out from under the collection hopper 101 for dust removal. After cleaning, the storage box is placed in the storage container. The storage box 201 is reinserted into its mounting position at the bottom of the collection hopper 101. Then, the pressing rod 203 is pressed down. Since the lower end of the pressing rod 203 and the limiting block 202 have mutually cooperating inclined surfaces, the pressing rod 203 will push the limiting block 202 to slide inward during its downward movement until it is fully embedded in the limiting hole of the storage box 201. At this time, the travel stop rod 204 inside the pressing rod 203 will pop outward under the restoring force of the elastic element and contact the lower surface of the support block 205, thereby achieving the positioning of the pressing rod 203 and the limiting block 202, ensuring that the storage box 201 is stably installed under the collection hopper 101 and preventing it from loosening or falling off during equipment operation.
