A sanding machine conveyor belt and its production equipment

Abstract

This application discloses a sanding machine conveyor belt and its production equipment. The sanding machine conveyor belt includes a bottom fabric and a soft damping layer. The upper surface of the damping layer is formed with a diamond pattern. The bottom of the diamond groove of the diamond pattern is formed with an exhaust hole that penetrates the damping layer vertically. The exhaust hole is a frustum-shaped hole with a diameter at the end near the diamond groove that is larger than the diameter at the end away from the diamond groove. The sanding machine conveyor belt production equipment is used to produce the above-mentioned sanding machine conveyor belt. When the workpiece is pressed against the upper surface of the sanding machine conveyor belt, due to the weight of the workpiece and the softness of the damping layer, the volume of the diamond groove becomes smaller. The air in the diamond groove is discharged along the exhaust hole. Since the exhaust hole is a frustum-shaped hole with a larger top and a smaller bottom, the air does not easily flow back after flowing out, thereby generating negative pressure in the diamond groove, which generates a certain suction force on the workpiece to compensate for insufficient friction.

Description

Technical Field

[0001] This application relates to the field of sanding machine conveyor belt technology, and in particular to a sanding machine conveyor belt and its production equipment. Background Technology

[0002] As the name suggests, a "sanding machine" is a mechanical device used to complete sanding work. It involves a wide range of industries and has a wide variety of products. However, industry professionals generally refer to those with automatic feeding systems as sanding machines, while others are called belt sanders, grinding wheels, polishing machines, etc.

[0003] Sanding and polishing are synonyms; both refer to the physical removal of unevenness, inconsistent thickness, or non-compliance with process requirements from materials and objects using tools such as sandpaper, grinding wheels, abrasive cloths, or non-woven polishing wheels. This process makes the materials smoother, flatter, and more uniform in thickness, thus meeting the required process standards. Sanding is used in various veneer production processes, standard structural component manufacturing, the toy and craft industry, the decoration and furniture industry, the flooring and wall panel building materials industry, and so on.

[0004] Currently, sanding machines mainly use conveyor belts to transport workpieces for sanding, so the friction between the workpiece and the conveyor belt is crucial. Existing conveyor belts increase friction through patterns on their outer surface, but there are still cases where the friction is insufficient. Summary of the Invention

[0005] To address insufficient friction, this application provides a sanding machine conveyor belt and its production equipment.

[0006] The technical solution provided in this application for a sanding machine conveyor belt and its production equipment is as follows: A sander conveyor belt includes a base fabric and a soft damping layer; the upper surface of the damping layer is formed with a diamond pattern; the bottom of the diamond groove of the diamond pattern is formed with an exhaust hole that penetrates vertically through the damping layer; the exhaust hole is a frustum hole and the diameter of the end near the diamond groove is larger than the diameter of the end away from the diamond groove.

[0007] By adopting the above technical solution, when the workpiece is pressed against the upper surface of the sander conveyor belt, due to the weight of the workpiece and the softness of the damping layer, the volume of the diamond groove becomes smaller, and the air in the diamond groove is discharged along the exhaust hole. Since the exhaust hole is a frustum hole with a larger top and a smaller bottom, the air does not easily flow back after it flows out, thus generating negative pressure in the diamond groove, which generates a certain suction force on the workpiece to make up for the lack of friction.

[0008] Optionally, the damping layer includes an intermediate fabric layer and a polyvinyl chloride (PVC) layer; the intermediate fabric layer has a plurality of connecting perforations formed thereon; the PVC layer consists of an upper PVC layer coated on the upper surface of the intermediate fabric layer, a lower PVC layer coated on the lower surface of the intermediate fabric layer, and a plurality of intermediate connecting posts passing through the connecting perforations; the vent holes correspond one-to-one with the intermediate connecting posts and are coaxially arranged.

[0009] By adopting the above technical solution, the presence of an intermediate fabric layer within the polyvinyl chloride layer increases the overall strength of the damping layer.

[0010] Optionally, the polyvinyl chloride layer may contain nitrile rubber.

[0011] By adopting the above technical solution, the wear resistance of the damping layer is improved by increasing the nitrile rubber, thereby increasing the service life of the conveyor belt.

[0012] A sanding machine conveyor belt production equipment includes an intermediate fabric layer unwinding device, an intermediate fabric layer conveying device, a perforation device, a bottom fabric feeding device, a coating and gluing device, and a finished product winding device. The intermediate fabric layer unwinding device is used to unwind the intermediate fabric layer. The intermediate fabric layer conveying device is used to convey the intermediate fabric layer to the finished product winding device. The perforation device is used for connecting and perforating the intermediate fabric layer. The bottom fabric feeding device is used to provide the bottom fabric. The coating and gluing device includes a coating and gluing box, a coating mechanism, and a gluing mechanism. The coating mechanism is used to coat the intermediate fabric layer with a polyvinyl chloride layer featuring a diamond pattern and vent holes to form a damping layer. The gluing mechanism is used to glue the bottom fabric and the damping layer together to form the finished conveyor belt. The finished product winding device is used to wind up the finished conveyor belt.

[0013] By adopting the above technical solution, the diamond pattern and vent holes are formed simultaneously during the formation of the damping layer, which effectively improves the production efficiency of the conveyor belt.

[0014] Optionally, the punching device includes a cuboid punching base, a punching lifting plate that is raised and lowered directly above the punching base, a punching lifting mechanism for driving the punching lifting plate to rise and fall, a plurality of punching needles uniformly fixed to the lower end face of the punching lifting plate, and a heating mechanism for heating the punching needles; the punching base is formed with a plurality of punching clearance holes for the punching needles to be inserted vertically; the punching clearance holes correspond one-to-one with the punching needles; a dust suction component is provided at the bottom of the punching base; the dust suction component is used to absorb the debris of the coked intermediate fabric layer.

[0015] By adopting the above technical solution, the heated punching needle descends together with the punching lifting plate. The high-temperature punching needle performs coking punching on the intermediate fabric layer. During this process, the debris generated in the intermediate fabric layer is sucked in by the dust suction component on the lower side, thereby preventing the debris from contaminating the intermediate fabric layer and reducing the possibility of affecting subsequent coating.

[0016] Optionally, the coating and bonding box includes a coating box body; the coating mechanism includes a paint spraying assembly, several coating forming seats, a coating driving assembly for driving the coating forming seats to move, a heating assembly for heating the coating forming seats, a scraping assembly, and a drying assembly; the coating forming seat includes a cuboid-shaped coating forming main plate and several frustum-shaped hole forming molds with the same shape as the exhaust holes; the widths of the coating forming seat and the coating box body are equal in the direction perpendicular to the conveying direction of the intermediate fabric layer; the upper end face of the coating forming main plate is formed into a forming surface corresponding to a diamond pattern, and the hole forming molds are formed on the upper end face of the coating forming main plate; the coating driving assembly is used to drive the coating forming seat to move along a rectangular line; the moving direction of the upper side of the coating forming seat is the same as the conveying direction of the intermediate fabric layer, and the moving direction of the lower side is opposite to the conveying direction of the intermediate fabric layer.

[0017] By adopting the above technical solution, the coating forming seat moves vertically from bottom to top, allowing the hole forming die to be inserted into the corresponding connecting perforation. Then, as the intermediate fabric layer moves horizontally intermittently, the coating spraying component sprays PVC coating, and then the scraping component scrapes off the excess PVC coating. Next, the drying component and the heated coating forming seat dry the PVC coating. Finally, the coating forming seat moves vertically from top to bottom, causing the hole forming die to detach from the PVC layer. This simple structure allows for the simultaneous forming of diamond patterns and vent holes, effectively improving the production efficiency of the conveyor belt.

[0018] Optionally, the coating molding main board has several horizontally distributed square columnar sliding connecting columns formed on its end face near the coating box; a pair of vertical inner sidewalls of the coating box opposite to the coating molding main board have rectangular sliding grooves formed for the sliding connecting columns to slide; the rectangular sliding groove includes an upper sliding groove horizontally arranged on the upper side, a lower sliding groove horizontally arranged on the lower side, and a pair of vertical sliding portions arranged between the upper sliding groove and the lower sliding groove; the vertical sliding portion includes several horizontally distributed vertical sliding grooves for the sliding connecting columns to slide vertically; the upper end of the vertical sliding groove communicates with the upper sliding groove, and the lower end communicates with the lower sliding groove; a pair of end faces of the coating molding main board perpendicular to the conveying direction of the intermediate fabric layer have connecting inserts and connecting slots respectively formed; the connecting slots are provided with upper and lower openings; a pair of adjacent The connecting blocks on the coating molding mainboard are inserted into the connecting slot from bottom to top and move synchronously. The coating drive assembly includes an upper horizontal drive component, a lower horizontal drive component, a first vertical drive component, and a second vertical drive component. The upper horizontal drive component is located below the upper sliding groove and is used to drive the coating molding seat to move horizontally along the upper sliding groove. The second vertical drive component is located below the lower sliding groove and is used to drive the coating molding seat to slide horizontally along the lower sliding groove. The first vertical drive component is located at the vertical sliding portion near the material receiving side of the middle fabric layer and is used to drive the coating molding seat to rise along the vertical sliding portion. The second vertical drive component is located at the vertical sliding portion away from the material receiving side of the middle fabric layer and is used to drive the coating molding seat to descend along the vertical sliding portion.

[0019] By adopting the above technical solution, the first vertical drive component drives the coating molding seat to move vertically upward along the vertical sliding part near the material receiving side of the middle fabric layer. Then, the upper horizontal drive component drives the coating molding seat to move horizontally along the direction parallel to the conveying direction of the middle fabric layer. Next, the second vertical drive component drives the coating molding seat to move vertically downward along the vertical sliding part away from the material receiving side of the middle fabric layer. Then, the second vertical drive component drives the coating molding seat to move horizontally in the direction parallel to the conveying direction of the middle fabric layer. In this way, the coating molding seat completes the rectangular line movement, which is simple in structure and demolding is completed during the movement. During the horizontal movement, due to the cooperation of the connecting plug and the connecting slot, all the coating molding main boards in the upper sliding groove move horizontally synchronously, and the coating molding main boards in the lower sliding groove move horizontally synchronously, which is beneficial to the damping layer forming and the movement of the coating molding main boards.

[0020] Optionally, the upper horizontal drive component and the lower horizontal drive component have the same structure; both the upper and lower horizontal drive components include a horizontally movable inverted T-shaped horizontal drive seat, a horizontal drive member for driving the horizontal drive seat to move horizontally, and a pair of right-angled triangular vertical limiting seats respectively vertically and elastically movable on both sides of the vertical part of the horizontal drive seat; the inclined surfaces of the pair of vertical limiting seats are away from the vertical part of the horizontal drive seat; a horizontally arranged cylindrical horizontal drive column is provided on the lower end surface of the coating molding main plate; the axial direction of the horizontal drive column is perpendicular to the conveying direction of the intermediate fabric layer; the diameter of the horizontal drive column is the same as the gap between the pair of vertical limiting seats; the coating The housing contains two horizontally arranged cylindrical upper and lower unlocking posts. The upper unlocking post is horizontally aligned with the vertical limiting seat of the upper horizontal drive component and located on the side of the horizontal drive seat away from the material receiving side of the middle fabric layer. The upper horizontal cross-section of the upper unlocking post is coplanar with the upper end surface of the horizontal drive seat of the upper horizontal drive component. The lower unlocking post is horizontally aligned with the vertical limiting seat of the lower horizontal drive component and located on the side of the horizontal drive seat closer to the material receiving side of the middle fabric layer. The upper horizontal cross-section of the lower unlocking post is coplanar with the upper end surface of the horizontal drive seat of the lower horizontal drive component. When the vertical limiting seat is at its lowest point, the upper edge of the vertical limiting seat is located on the horizontal plane where the upper end surface of the horizontal drive seat is located.

[0021] By adopting the above technical solution, when the horizontal drive seat moves away from the upper or lower unlocking post, a pair of vertical limiting seats are at the top and the horizontal drive post is located between the pair of vertical limiting seats. Then, the horizontal drive seat moves to the upper or lower unlocking post. During this process, under the action of the upper or lower unlocking post, the vertical limiting seat on the corresponding side descends until the upper edge of the vertical limiting seat is located on the horizontal plane where the upper end face of the horizontal drive seat is located. This drives the coating molding seat to move a distance. Subsequently, the horizontal drive seat moves away from the unlocking post or lower unlocking post. During this process, under the action of the horizontal drive post, the vertical limiting seat on the corresponding side descends until the horizontal drive post enters between the pair of vertical limiting seats. The vertical limiting seats rise back to their original position, thus preparing for the next translation. The structure is simple and can quickly achieve connection and separation while realizing translation.

[0022] Optionally, the coating and bonding box includes a bonding box; the bonding mechanism includes a plugging component, an adhesive application component, and a bonding component; the plugging component is used to plug the vent hole to prevent adhesive from entering; the adhesive application component is used to apply adhesive to the damping layer; the bonding component is used to bond the bottom fabric to the damping layer; the plugging component includes a vertically lifting plugging plate, a plugging lifting drive for driving the plugging plate, and a plurality of conical plugging cones formed on the upper end surface of the plugging plate; the lower part of the plugging cone has the same shape as the vent hole.

[0023] By adopting the above technical solution, the conical plugging cone ensures that the smaller diameter end of the vent hole will not be blocked by glue during adhesive application, reducing the possibility of needing to pass through the hole later and improving production quality.

[0024] Optionally, the glue application component includes a pair of glue application moving blocks, a glue application moving drive for driving the pair of glue application moving blocks to move horizontally, a pair of glue rolling support plates respectively vertically and vertically mounted on the pair of glue application moving blocks, a glue rolling lifting drive for driving the pair of glue rolling support plates to move vertically and vertically, and a horizontally mounted glue rolling roller rotatably connected between the upper ends of the pair of glue rolling support plates; the glue rolling roller includes a hollow glue storage roller and a glue layer disposed on the outer cylindrical surface of the glue storage roller; a plurality of evenly distributed radially penetrating glue outlet holes are formed on the side wall of the glue storage roller.

[0025] By adopting the above technical solution, the glue in the glue storage roller flows out along the glue outlet on the lower side and enters the glue coating layer during its rotation. Then the glue penetrates the glue coating layer and coats the damping layer, so the glue coating is uniform.

[0026] In summary, the beneficial effects of this application are as follows: 1. When the workpiece is pressed against the upper surface of the sander conveyor belt, due to the weight of the workpiece and the softness of the damping layer, the volume of the diamond groove becomes smaller. The air in the diamond groove is discharged along the exhaust hole. Since the exhaust hole is a frustum hole that is larger at the top and smaller at the bottom, the air does not easily flow back after it flows out, thus generating negative pressure in the diamond groove, which generates a certain suction force on the workpiece to compensate for the lack of friction.

[0027] 2. The presence of an intermediate fabric layer within the PVC layer increases the overall strength of the damping layer.

[0028] 3. The diamond pattern and vent holes are formed simultaneously during the formation of the damping layer, which effectively improves the production efficiency of the conveyor belt. Attached Figure Description
