Technical Field
[0001] This utility model belongs to the technical field of grinding equipment, specifically relating to a device for enclosing the production area of a grinding mill. Background Technology
[0002] A grinding mill is a tool that uses abrasives to grind, polish, and cut the surface of a workpiece. It is usually powered by electricity, has high power, high speed, and strong grinding force, and is suitable for grinding various materials.
[0003] Due to the nature of their operation, grinding mills generate a large amount of sparks and dust during the intense friction between the high-speed rotation of the grinding wheel and the surface of the workpiece. Long-term exposure to such an environment can affect the health of operators. Furthermore, existing grinding mills typically use a single-head grinding method, which cannot adequately meet the needs of processing multiple workpieces simultaneously, leading to decreased work efficiency, which in turn prolongs the production time and increases production costs for enterprises. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for enclosing the production area of a mill.
[0005] The technical solution adopted to solve the above-mentioned technical problems is: to provide a device for enclosing the production area of a mill, including a housing, on one side of which are symmetrically arranged sliding doors, which are movably connected to each other by a buckle mechanism, a support frame is provided inside the housing, a grinding mechanism is rotatably connected to the top of the support frame, a power output mechanism is provided at the bottom of the support frame, the power output mechanism and the grinding mechanism are connected by a transmission belt, and a clamping mechanism is provided on one side of the working end of the grinding mechanism.
[0006] The above technical solution, by setting up a double-head grinding structure, meets the usage requirements of processing two workpieces simultaneously. By controlling the rotation of the grinding discs at both ends with a single drive source, production efficiency is improved while reducing the labor costs of enterprises.
[0007] Furthermore, the grinding mechanism includes a drive shaft, with both ends of the drive shaft rotatably connected to the top of the support frame. A first drive wheel is fixedly connected to the outer wall of the drive shaft, and the first drive wheel is rotatably connected to a drive belt. A drive rod is fixedly connected to both ends of the drive shaft, and a first limiting block is slidably sleeved on the outer wall of the drive rod. A second limiting block is correspondingly provided on one side of the first limiting block. A rotating shaft is fixedly connected to the end of the second limiting block away from the first limiting block. A grinding disc is fixedly connected to the end of the rotating shaft away from the second limiting block. A support plate is rotatably connected to the outer wall of the rotating shaft.
[0008] Furthermore, the second limiting block coincides with the axis of the first limiting block, and the second limiting block and the first limiting block are engaged and connected.
[0009] Furthermore, limit protrusions are fixedly connected to both sides of the transmission rod, and a limit through groove is opened between the two ends of the first limit block, with the limit protrusions corresponding to the limit through groove.
[0010] Through the above technical solution, the first transmission wheel drives the transmission shaft to rotate, the rotation of the transmission shaft drives the transmission rods fixed at both ends to rotate, the transmission rods drive the first limit block to rotate through the limiting protrusions fixed on both sides and the limiting through slots opened at both ends of the first limit block through the limiting action, the first limit block drives the second limit block and the grinding disc to rotate together through the engaging connection between the first limit block and the second limit block, and then the grinding disc grinds the surface of the workpiece.
[0011] Furthermore, the clamping mechanism includes a first clamping plate, which is U-shaped. A limiting groove is formed on the bottom wall of the first clamping plate. A second clamping plate is slidably connected in the limiting groove. A threaded rod is rotatably connected to one side of the second clamping plate. The threaded rod passes through the side wall of the first clamping plate and is threadedly connected to the first clamping plate.
[0012] With the above technical solution, when the threaded rod rotates, it pushes the second clamping plate to move linearly along the direction of the limiting slide groove through the threaded connection with the first clamping plate, thereby completing the clamping of the workpiece.
[0013] Furthermore, limit plates are respectively provided on both sides of the first clamping plate, and a second limit hole is opened on the side wall of the limit plate. The second limit holes are arranged sequentially along the axial direction of the limit plate. A first limit hole is opened on both sides of the bottom wall of the first clamping plate, and a limit post is inserted between the first limit hole and the second limit hole.
[0014] With the above technical solution, when it is necessary to adjust the processing height of the clamped workpiece, first adjust the relative position between the first clamping plate and the limiting plate, and then insert the limiting post between the first limiting hole and the second limiting hole for limiting and fixing.
[0015] Furthermore, the latching mechanism includes a first latching block, a lever movably connected to the bottom end of the first latching block, the lever being rotatably connected to the side wall of the sliding door, a limit frame slidably connected to the outer wall of the first latching block, the side wall of the limit frame being fixedly connected to the side wall of the sliding door, the end of the lever near the first latching block being connected to the limit frame via a spring, a second latching block being correspondingly provided on one side of the top of the first latching block, a limit notch being provided on the bottom wall of the second latching block, and the second latching block being fixedly connected to the side wall of the sliding door.
[0016] With the above technical solution, when the sliding doors on both sides are closed, the side wall of the second locking block presses against the top side wall of the first locking block, and the first locking block begins to move downward. When the second locking block completely passes the top of the first locking block, the first locking block begins to move upward under the elastic force of the hanging spring. At this time, the limiting notch opened on the bottom wall of the second locking block engages with the first locking block, thus completing the limiting and fixing of the sliding doors on both sides.
[0017] Furthermore, the power output mechanism includes a first motor, the output end of which is fixedly connected to a second transmission wheel, which is rotatably connected to a transmission belt.
[0018] Through the above technical solution, the first motor starts and drives the second transmission wheel to rotate, and the second transmission wheel drives the first transmission wheel to rotate through the transmission belt.
[0019] The beneficial effects of this utility model are as follows:
[0020] This invention, by setting up a double-head grinding structure, meets the need for simultaneous processing of two workpieces. A single drive source controls the rotation of the grinding discs at both ends, improving production efficiency while reducing labor costs. A first motor drives a second transmission wheel, which in turn drives the first transmission wheel, thereby causing a transmission rod to rotate a first limiting block. The engaging connection between the first and second limiting blocks allows the second limiting block to drive the grinding disc, thus completing the workpiece processing. Furthermore, the movable connection between the first and second limiting blocks allows the equipment to operate on one side only. The ability to switch between single-sided and dual-sided simultaneous processing improves the equipment's production flexibility. By installing push-pull plates on the side walls of the housing, the dust and sparks generated during milling are prevented from splashing out and affecting the operators, thus protecting their health. When the push-pull doors on both sides are closed, the side wall of the second locking block presses against the top side wall of the first locking block, causing the first locking block to begin moving downwards. When the second locking block completely passes the top of the first locking block, the first locking block begins to move upwards under the elastic force of the hanging spring. At this point, the limiting notch on the bottom wall of the second locking block engages with the first locking block, completing the limiting and fixing of the push-pull doors on both sides.

[0029] The grinding mechanism 2 includes a drive shaft 210, with both ends of the drive shaft 210 rotatably connected to the top of the support frame 6.

The second transmission wheel 802 drives the first transmission wheel 211 to rotate through the transmission belt 7.
[0032] The first transmission wheel 211 drives the transmission shaft 210 to rotate. The rotation of the transmission shaft 210 drives the transmission rod 212, which is fixed at both ends, to rotate. The transmission rod 212 drives the first limit block 207 to rotate through the limiting protrusions 205 fixedly connected on both sides and the limiting through slots 208 opened at both ends of the first limit block 207. The first limit block 207 drives the second limit block 203 and the grinding disc 201 to rotate together through the engaging connection between the first limit block 207 and the second limit block 203. Then, the grinding disc 201 grinds the surface of the workpiece.
[0033] The clamping mechanism 3 includes a first clamping plate 301, which is U-shaped. A limiting groove 302 is provided on the bottom wall of the first clamping plate 301. A second clamping plate 304 is slidably connected in the limiting groove 302. A threaded rod 303 is rotatably connected to one side of the second clamping plate 304.

When the threaded rod 303 rotates, through its threaded connection with the first clamping plate 301, the threaded rod 303 pushes the second clamping plate 304 to move linearly along the limiting groove 302, thereby completing the clamping of the workpiece.
[0034] Limiting plates 305 are respectively provided on both sides of the first clamping plate 301. The side wall of the limiting plate 305 is provided with a second limiting hole 307. The second limiting holes 307 are arranged sequentially along the axial direction of the limiting plate 305.

[0036] The latching mechanism 4 includes a first latching block 403, a lever 405 is movably connected to the bottom end of the first latching block 403, the lever 405 is rotatably connected to the side wall of the sliding door 5, a limit frame 406 is slidably connected to the outer wall of the first latching block 403, the side wall of the limit frame 406 is fixedly connected to the side wall of the sliding door 5, the end of the lever 405 near the first latching block 403 is connected to the limit frame 406 by a hanging spring 404, a second latching block 401 is correspondingly provided on one side of the top of the first latching block 403, a limit notch 402 is opened on the bottom wall of the second latching block 401, and the second latching block 401 is fixedly connected to the side wall of the sliding door 5.
[0037] When the sliding doors 5 on both sides are closed, the side wall of the second locking block 401 presses against the top side wall of the first locking block 403, and the first locking block 403 begins to move downward. When the second locking block 401 completely passes the top of the first locking block 403, the first locking block 403 begins to move upward under the elastic force of the hanging spring 404. At this time, the limiting notch 402 opened on the bottom wall of the second locking block 401 engages with the first locking block 403, thus completing the limiting and fixing of the sliding doors 5 on both sides.
[0038] In use, this utility model first rotates the threaded rod 303. Through the threaded connection between the threaded rod 303 and the first clamping plate 301, the threaded rod 303 pushes the second clamping plate 304 to move linearly along the direction of the limiting slide groove 302, thus clamping the workpiece. At this time, the first motor 801 is started, which drives the second transmission wheel 802 to rotate. The second transmission wheel 802 drives the first transmission wheel 211 to rotate through the transmission belt 7. The first transmission wheel 211 drives the transmission shaft 210 to rotate.

When the first limiting block 207 rotates, it drives the second limiting block 203 and the grinding disc 201 to rotate together through the engagement connection between the first limiting block 207 and the second limiting block 203. The grinding disc 201 then grinds the surface of the workpiece. During the grinding process, the sliding door 5 is closed. At this time, the side wall of the second locking block 401 presses against the top side wall of the first locking block 403, and the first locking block 403 begins to move downward. When the second locking block 401 completely passes the top of the first locking block 403, the first locking block 403 begins to move upward under the elastic force of the hanging spring 404. At this time, the limiting notch 402 opened on the bottom wall of the second locking block 401 engages with the first locking block 403, thus completing the limiting and fixing of the two sliding doors 5.
