Description

Technical Field

[0001] This utility model belongs to the technical field of polishing equipment, and specifically relates to a polishing equipment for processing the edge of a fabric core conveyor belt. Background Technology

[0002] During calendering, bonding, vulcanization, or cutting, the edges of conveyor belts often exhibit phenomena such as excess rubber accumulation (rubber edge, rubber nodule), exposed fibers, warping or delamination, and irregular serrated edges. Mechanical trimming can smooth, neat, and protrusion-free edges, preventing cracking caused by stress concentration during subsequent use.

[0003] Most existing grinding equipment for processing the edges of fabric core conveyor belts involves welding a fixed frame onto a workbench, with grinding components at both ends. The conveyor belt moves from the center of the fixed frame, allowing for grinding of the conveyor belt edges. During the grinding process, debris is generated. While vacuuming can remove this debris, the angle of the vacuum cleaner's hood cannot be adjusted, limiting it to a single direction. Changing the type of grinding wheel, adjusting the grinding depth, or adjusting the belt thickness alters the dust generation point and spray angle, and the fixed hood cannot be adjusted accordingly. This can result in almost no dust being collected under certain conditions, making the dust removal effect highly dependent on the initial installation accuracy and having a very low tolerance for error. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of existing technologies by providing a grinding device for processing the edge of a fabric core conveyor belt. By setting a rotating plate, a rotating rod drives a vacuum cleaner to rotate via the rotating plate, and the vacuum cleaner drives the dust collection hood to rotate, thereby adjusting the angle at which the dust collection hood picks up dust. During the grinding process, dust flies out at high speed along the tangent of the grinding wheel, and its angle changes with the rotation direction of the grinding wheel and the thickness of the conveyor belt. By adjusting the angle of the dust collection hood, it can always face the mainstream direction of dust, achieving efficient source capture and improving dust removal efficiency by more than 30%.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a grinding device for processing the edge of a fabric core conveyor belt, including a worktable, a support frame provided at the upper middle part of the worktable, a mounting frame provided at the upper end of the support frame, sliders symmetrically slidably provided inside the mounting frame, a fixing block provided at the lower end of each slider, a grinding component provided on the fixing block, a fixing frame provided at the right end of the fixing block, a rotating column rotatably provided inside the fixing frame, rotating plates provided at both ends of the rotating column extending to the outside of the fixing frame, a vacuum cleaner provided between the two rotating plates, a vacuum cleaner hood provided on the vacuum cleaner, and a driving component for driving the vacuum hood to rotate provided inside the fixing frame.

[0006] As a further improvement of this utility model, the driving component includes a worm gear rotatably disposed inside the fixed frame, a rotating rod rotatably disposed in the middle of the fixed frame, a worm wheel meshing with the worm gear in the middle of the rotating rod, and a motor 1 disposed at the front end of the fixed frame, the output end of the motor 1 being connected to the worm gear via a coupling.

[0007] As a further improvement of this utility model, the mounting bracket is internally equipped with a bidirectional lead screw, and two sliders are respectively located at both ends of the bidirectional lead screw and are threadedly connected to the bidirectional lead screw. The front end of the mounting bracket is equipped with a second motor, and the output end of the second motor is connected to the bidirectional lead screw through a coupling.

[0008] As a further improvement of this utility model, a support plate is provided on the upper left side of the support frame, a telescopic push rod is provided in the middle of the support plate, and a pressing plate is provided at the telescopic end of the telescopic push rod extending to the lower end of the support plate.

[0009] As a further improvement of this utility model, limit rods are symmetrically arranged at the upper end of the extrusion plate, the limit rods are slidably connected to the support plate, and a limit plate is provided at the upper end of the limit rods.

[0010] As a further improvement of this utility model, a positioning frame one is provided at the left end of the workbench, and a rotating roller is rotatably provided at the upper end of the positioning frame one. A positioning frame two is provided at the right end of the workbench, and a winding roller is rotatably provided at the upper end of the positioning frame two.

[0011] As a further improvement of this utility model, a support base is provided at the lower end of the workbench, and a support bar is provided between every two adjacent support bases. Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting up a rotating plate, the rotating rod drives the vacuum cleaner to rotate via the plate, and the vacuum cleaner drives the dust hood to rotate, thereby adjusting the angle at which the dust hood picks up dust. During the grinding process, dust flies out at high speed along the tangent of the grinding wheel, and its angle changes with the rotation direction of the grinding wheel, the thickness of the conveyor belt, and the type of grinding wheel (flat grinding, chamfering, etc.). By adjusting the angle of the dust hood, it can always face the mainstream direction of dust, achieving efficient collection at the source and improving dust removal efficiency by more than 30%.

[0012] Secondly, by setting a limiting rod, which is slidably connected to the support plate, and a limiting plate is set at the upper end of the limiting rod, if the extrusion plate is only connected to a single point during the pushing and pulling process of the telescopic push rod, it is easy for the extrusion plate to tilt, shake or jam due to uneven load, small lateral force of the push rod, and asymmetry of the reaction force of the belt. As a high-rigidity guide column, the limiting rod forces the extrusion plate to slide only in the vertical direction, eliminating any lateral displacement or rotational degree of freedom, thereby making the pressing action of the extrusion plate smooth and precise, and the pressure evenly distributed on the belt surface.

[0013] Thirdly, by setting up a vacuum cleaner and a dust cover, dust can be extracted during the polishing process to avoid secondary dust pollution. If the dust is not removed in time, it will fall back onto the conveyor belt surface, affecting subsequent gluing, printing, or joint vulcanization. Timely dust removal can ensure polishing consistency, ensure smooth and clean edges, and improve product yield and consistency.

[0014] Fourth, by setting up support bars, the high-speed rotating grinding wheel will generate high-frequency vibrations during the grinding process. If the support structure is loose, the vibration will be amplified through the worktable, resulting in vibration marks and loose bolts on the grinding surface. The support bars, as transverse reinforcing ribs, increase structural damping, suppress vibration propagation, and improve the dynamic stability of the system, thereby making the grinding edge smoother and the equipment run more quietly and reliably.

Detailed Implementation

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] like Figure 1 , 2As shown in Figure 3, a grinding device for processing the edge of a fabric core conveyor belt includes a worktable 101. A support frame 102 is provided at the middle of the upper end of the worktable 101. A mounting frame 103 is provided at the upper end of the support frame 102. Slider blocks 104 are symmetrically slidably arranged inside the mounting frame 103. A fixing block 105 is provided at the lower end of each of the two sliders 104. A grinding component 106 is provided on the fixing block 105. A fixing frame 107 is provided at the right end of the fixing block 105. A rotating column 108 is rotatably arranged inside the fixing frame 107. Both ends of the rotating column 108 extend to the outside of the fixing frame 107 and are provided with rotating plates 109. A vacuum cleaner 110 is arranged between the two rotating plates 109. A vacuum cleaner hood 111 is provided on the vacuum cleaner 110. A driving component for driving the vacuum cleaner hood 111 to rotate is provided inside the fixing frame 107.

[0020] like Figure 2 , 3 As shown in Figure 4, the driving component includes a worm gear 201 rotatably disposed inside the fixed frame 107. A rotating rod 202 is rotatably disposed in the middle of the fixed frame 107. A worm wheel 203 meshing with the worm gear 201 is disposed in the middle of the rotating rod 202. A motor 204 is disposed at the front end of the fixed frame 107. The output end of the motor 204 is connected to the worm gear 201 through a coupling. When the motor 204 is started, the output end of the motor 204 drives the worm gear 201 to rotate. The worm gear 201 drives the worm wheel 203 to rotate. The worm wheel 203 drives the rotating rod 202 to rotate. The rotating rod 202 drives the vacuum cleaner 110 to rotate through the rotating plate 109. The vacuum cleaner 110 drives the dust cover 111 to rotate, thereby rotating the dust cover 111. The angle of dust collection is adjusted by the worm gear 203 and worm 201 mechanism, which has a natural self-locking characteristic (when the lead angle is less than the friction angle, the worm gear 203 cannot drive the worm 201 in the reverse direction). After the dust collection hood 111 is adjusted to the target angle, it can be firmly locked without additional braking devices. Even under equipment vibration or airflow impact, the angle will not drift, ensuring long-term stable alignment with the dust source. During the grinding process, the dust flies out at high speed along the tangent direction of the grinding wheel. Its angle changes with the rotation direction of the grinding wheel, the thickness of the conveyor belt, and the type of grinding wheel (flat grinding, chamfering, etc.). By adjusting the angle of the dust collection hood 111, it can always be aligned with the mainstream direction of the dust, achieving efficient collection at the source and improving the dust removal efficiency by more than 30%.

[0021] like Figure 2 , 3As shown, a bidirectional lead screw 205 is rotatably mounted inside the mounting frame 103. Two sliders 104 are located at both ends of the bidirectional lead screw 205 and are threadedly connected to it. A second motor 206 is mounted at the front end of the mounting frame 103. The output end of the second motor 206 is connected to the bidirectional lead screw 205 via a coupling. When the second motor 206 is started, its output end drives the bidirectional lead screw 205 to rotate. The bidirectional lead screw 205 drives the sliders 104 to move along the mounting frame 103, which in turn causes the sliders 104 to move the fixed block 105. The fixed block 105 then drives the grinding parts 106 to move, thereby adjusting the spacing between the grinding parts 106. Since the conveyor belt has a wide width range, traditional fixed-spacing grinding heads are only suitable for a single or narrow bandwidth. By controlling the bidirectional lead screw 205 with the second motor 206, the distance between the grinding parts 106 on both sides can be precisely and continuously adjusted to match the actual width of the conveyor belt, significantly improving equipment utilization and production line flexibility.

[0022] like Figure 2 As shown, a support plate 301 is provided on the upper left side of the support frame 102. A telescopic push rod 302 is provided in the middle of the support plate 301. The telescopic end of the telescopic push rod 302 extends to the lower end of the support plate 301 and is provided with an extrusion plate 303. When the telescopic push rod 302 is activated, the telescopic end of the telescopic push rod 302 drives the extrusion plate 303 to move up and down, thereby allowing the extrusion plate 303 to extrude force on the conveyor belt, preventing the conveyor belt from wrinkling. Conveyor belts (especially thin or wide belts) are prone to local wrinkling due to their own weight, uneven tension, or edge warping when unrestrained. When the wrinkled area passes through the grinding head, the uneven grinding depth may cause uneven edges. The extrusion plate 303 can gently press the belt surface from above, forcibly flattening the belt body, so that it passes through the grinding area with a stable plane, improving grinding efficiency.

[0023] like Figure 1 , 4 As shown, the upper end of the extrusion plate 303 is symmetrically provided with limit rods 304. The limit rods 304 are slidably connected to the support plate 301. The upper end of the limit rods 304 is provided with a limit plate. During the pushing and pulling process, if the telescopic push rod 302 is only connected to the extrusion plate 303 at a single point, the extrusion plate 303 is prone to tilting, shaking or jamming due to uneven load, small lateral force of the push rod, and asymmetry of the reaction force of the belt. The limit rod 304, as a high-rigidity guide column, forces the extrusion plate 303 to slide only in the vertical direction, eliminating any lateral displacement or rotational freedom, thereby making the pressing action of the extrusion plate 303 stable and precise, and the pressure evenly distributed on the belt surface.

[0024] like Figure 1 , 4As shown, a positioning frame 306 is provided at the left end of the worktable 101, and a rotating roller 307 is rotatably provided at the upper end of the positioning frame 306. A positioning frame 308 is provided at the right end of the worktable 101, and a take-up roller 309 is rotatably provided at the upper end of the positioning frame 308. A motor 3 is provided at the front end of the positioning frame 308, and the output end of the motor 3 is connected to the take-up roller 309 through a coupling.

[0025] like Figure 1 , 4 As shown, a support base is provided at the lower end of the workbench 101.

[0026] In use, the fabric core conveyor belt is fitted onto the surface of the rotating roller 307. Motor 206 is started, and its output drives the bidirectional lead screw 205 to rotate. The lead screw 205 then moves the slider 104 along the mounting frame 103, which in turn moves the fixed block 105. The fixed block 105 then moves the grinding pieces 106, thus adjusting the distance between the grinding pieces 106. By controlling the bidirectional lead screw 205 with motor 206, the distance between the grinding pieces 106 on both sides can be precisely and continuously adjusted to match the actual width of the conveyor belt, significantly improving equipment utilization and production line flexibility. The fabric core conveyor belt is activated, and then one end of the conveyor belt is pulled out from the surface of the rotating roller 307, passes through the extrusion plate 303 and the grinding part 106, and is wound around the surface of the take-up roller 309. The telescopic push rod 302 is activated, and the telescopic end of the telescopic push rod 302 drives the extrusion plate 303 to move up and down, so that the extrusion plate 303 can squeeze the conveyor belt to avoid wrinkles. The conveyor belt (especially the thinner or wider belt) is prone to local wrinkling due to its own weight, uneven tension or edge warping when it is unrestrained. The extrusion plate 303 can lightly press the belt surface from above, forcibly flatten the belt body, and make it pass through the grinding area with a stable plane, thereby improving the grinding efficiency. Next, start motor three. The output of motor three drives the winding roller 309 to rotate, thus winding the fabric core conveyor belt. During the winding process, start the abrasive component 106 to abrade the fabric core conveyor belt. During abrasion, dust will fly up. Turn on the vacuum cleaner 110, and the dust can be sucked up through the dust suction hood 111. Start motor one 204. The output of motor one 204 drives the worm gear 201 to rotate. The worm gear 201 drives the worm wheel 203 to rotate. The worm wheel 203 drives the rotating rod 202 to rotate. The rotating rod 202 drives the vacuum cleaner 110 to rotate through the rotating plate 109. The vacuum cleaner 110 drives the dust suction hood 111 to rotate, thereby sucking up the dust through the dust suction hood 111. The angle can be adjusted. The worm gear 203 and worm 201 mechanism has a natural self-locking characteristic (when the lead angle is less than the friction angle, the worm gear 203 cannot drive the worm 201 in the reverse direction). After the dust hood 111 is adjusted to the target angle, it can be firmly locked without additional braking devices. Even under equipment vibration or airflow impact, the angle will not drift, ensuring long-term stable alignment with the dust source. During the grinding process, the dust flies out at high speed along the tangent direction of the grinding wheel. Its angle changes with the rotation direction of the grinding wheel, the thickness of the conveyor belt, and the type of grinding wheel (flat grinding, chamfering, etc.). By adjusting the angle of the dust hood 111, it can always be aligned with the mainstream direction of the dust, achieving efficient collection at the source and improving dust removal efficiency by more than 30%.

[0027] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a support bar is provided between every two adjacent support bases. During the grinding process, the high-speed rotating grinding wheel will generate high-frequency vibration. If the support structure is loose, the vibration will be amplified through the worktable 101, resulting in vibration marks, loose bolts, and other phenomena on the grinding surface. The support bar, as a transverse reinforcing rib, increases structural damping, suppresses vibration propagation, and improves the dynamic stability of the system, thereby making the grinding edge smoother and the equipment operation quieter and more reliable.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
