Description

Technical Field

[0001] This invention relates to the field of fixed transportation technology for plastics, specifically a conveying device with a fixing mechanism for plastic processing. Background Technology

[0002] Patent publication number CN210619256U relates to a conveying device with a fixing mechanism for processing plastic bags. The conveying device includes a base plate, with a first transmission wheel and a second transmission wheel fixedly connected from left to right on both sides of the top of the base plate via brackets. A conveyor belt is driven between the surfaces of the first and second transmission wheels. The conveying device with a fixing mechanism for processing plastic bags provided by this patent uses the elastic force of springs to compress two second rotating blocks, which in turn compress a compression plate, which in turn compresses compression columns. The plastic bags are fixed and clamped by four compression columns, improving the stability during conveying. A second motor drives a lead screw to rotate, which in turn moves a threaded cylinder, which in turn moves a support block, grounding the moving block and raising the device. The device's operating height can be adjusted to adapt to different usage environments, improving its practicality. The aforementioned patent addresses the issue of adjusting the height of the device to adapt to different usage environments, but it does not consider that the plastic may not be centered on the conveyor belt. If the plastic is not fixed in the middle of the conveyor belt, it may affect the subsequent processing of the plastic. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a conveying device with a fixed mechanism for plastic processing, comprising a conveying device, a drive motor fixedly installed on the left side of the conveying device, a feeding box fixedly installed on the top of the conveying device, a fixed device provided on the top of the conveying device, a feeding device provided inside the feeding box, and a discharging device provided inside the feeding box. The fixing device includes a mounting plate, a fixed plate, a servo motor, a rotating shaft, a rotating block, a short rod, a mounting shaft, a rotating plate, a moving plate, a fixed rod, an L-shaped plate, a long plate, a square block, and an inclined plate. The mounting plate is fixedly mounted on the top of the conveying device. The fixed plate is fixedly mounted on the top of the mounting plate. The servo motor is fixedly mounted on the top of the fixed plate. The rotating shaft drives through the top of the fixed plate and through the mounting plate. The rotating shaft is fixedly mounted at the output end of the servo motor. The rotating block is fixedly mounted on the circumferential surface of the rotating shaft. The short rod is fixedly mounted on the circumferential surface of the rotating shaft. The mounting shaft is rotatably mounted on the bottom of the mounting plate. The rotating plate is fixedly mounted on the circumferential surface of the mounting shaft. The moving plate slides through the fixed plate and slides on the top of the mounting plate. The L-shaped plate slides on the top of the mounting plate. The square block is fixedly mounted inside the conveying device. The inclined plate is rotatably mounted on the bottom of the L-shaped plate. The long plate slides on the top of the mounting plate. A toothed block is fixedly mounted on the top of the long plate. By setting up the fixing device, the plastic on the conveying device is smoothed out, preventing plastic accumulation from affecting the working efficiency of the conveying device, and fixing the plastic in the middle position of the conveying device.

[0005] According to the above technical solution, the rotating block contacts the moving plate, the short rod contacts the rotating plate, and a first spring is fixedly installed between the moving plate and the fixed plate. By setting the first spring, the moving plate can be reset by the elastic force of the first spring, and the plastic on the conveying device can be smoothed by the contact between the short rod and the rotating plate.

[0006] According to the above technical solution, the side of the moving plate closest to the L-shaped plate and the long plate is set as an inclined surface, and the side of the L-shaped plate and the long plate closest to the moving plate is set as an inclined surface. The movement of the L-shaped plate and the long plate is realized by setting the inclined surface, and the plastic is moved in the center.

[0007] According to the above technical solution, the feeding device includes a gear shaft, a rack, a crossbar, a baffle, a connecting rod, a connecting rod, a connecting shaft, a deflector plate, a screen, and a curved panel. The screen is fixedly installed inside the feeding box, the curved panel is fixedly installed inside the feeding box, the gear shaft is rotatably installed on the right side of the feeding box, and the gear shaft meshes with the toothed block on the top of the long plate. The feeding box has grooves on both sides, the baffle is slidably installed inside the grooves, the rack is fixedly installed on the right side of the baffle, the gear shaft meshes with the rack, the crossbar is fixedly installed in front of the rack, the connecting shaft rotatably passes through the feeding box, the connecting rod is fixedly installed at the end of the connecting shaft that protrudes from the feeding box, the connecting rod is rotatably installed on the right side of the connecting rod, and the deflector plate is fixedly installed on the circumferential surface of the connecting shaft. By setting up the feeding device, the plastic is controlled to enter the intermittent conveying device 1, and the plastic on the screen surface is agitated, thereby improving the efficiency of screening smaller plastics.

[0008] According to the above technical solution, the end of the crossbar near the connecting rod is set as an arc surface, the connecting rod is in contact with the connecting rod, and multiple connecting rods are provided and all are connected to the connecting rod. The contact between the crossbar and the connecting rod causes the actuating plate to rotate, thereby increasing the contact area between the plastic and the screen and preventing small plastic pieces from falling into the conveying device, thus affecting subsequent processing.

[0009] According to the above technical solution, the actuating plate is in contact with the screen, and the baffle is in contact with the screen. Intermittent feeding is achieved by setting the baffle, thus avoiding a reduction in work efficiency.

[0010] According to the above technical solution, the discharge device includes a discharge trough, a positioning plate, an inclined block, a bent rod, a bent plate, a protrusion, a swing plate, and a brush. The front of the conveying device has an opening slot, the discharge trough is located inside the opening slot, the positioning plate is fixedly installed inside the discharge trough, the inclined block is rotatably installed at the bottom of the positioning plate, the bent rod is rotatably installed at the front of the baffle, the bent plate is fixedly installed at the front of the baffle, the protrusion is fixedly installed at the bottom of the swing plate, the swing plate is rotatably installed inside the feeding box, and the brush is fixedly installed at the top of the swing plate. By setting up the discharge device, smaller plastics that have been screened out are discharged, preventing smaller plastics from remaining inside the discharge trough.

[0011] According to the above technical solution, the bent rod contacts the swing plate, and a second spring is fixedly installed between the swing plate and the feeding box. The contact between the bent rod and the swing plate causes the brush to contact the screen and clean the screen mesh, thus avoiding clogging and reducing work efficiency.

[0012] This invention provides a conveying device with a fixing mechanism for plastic processing. It has the following advantages: (1) In this invention, the servo motor starts and drives the rotating shaft to rotate, the rotating shaft drives the short rod to rotate, the short rod rotates and contacts the rotating plate, the short rod continues to rotate and drives the rotating plate to rotate, the rotating plate can smooth the raw materials on the conveying device, prevent the raw materials from piling up and reducing the working efficiency of the conveying device, at the same time the rotating shaft rotates and drives the rotating block to rotate, the rotating block rotates and contacts the moving plate, the rotating block continues to rotate and causes the moving plate to move, the moving plate causes the inclined surface of the moving plate to contact the L-shaped plate and the long plate, causing the L-shaped plate to move, the L-shaped plate moves and drives the inclined plate to move, when the inclined plate moves to no When in contact with the fixed rod, the inclined plate rotates under the influence of the torsion spring. When the rotating block continues to rotate and no longer contacts the moving plate, the L-shaped plate resets under the influence of the spring force. The reset of the L-shaped plate causes the inclined plate to contact the fixed rod. The continued reset of the L-shaped plate causes the inclined plate to rotate under the influence of the fixed rod, pushing the plastic at the edge of the conveying device to the middle position, fixing the plastic in the middle position of the conveying device, and preventing the plastic from entering the conveying device and causing damage to the device when it is at the edge of the conveying device. At the same time, when the moving plate moves, the inclined surface of the moving plate contacts the L-shaped plate and the long plate, causing the long plate to move.

[0013] (2) In this invention, when plastic enters the feeding box, the plastic falls on the screen surface. Due to the movement of the long plate, the gear shaft that meshes with the toothed block at the top of the long plate rotates. The rotation of the gear shaft drives the rack to move. The movement of the rack drives the baffle to move, which prevents the plastic from continuously entering the conveying device, causing the conveying device to be overloaded and reducing the working efficiency. At the same time, the movement of the rack drives the crossbar to move. The crossbar moves and contacts the connecting rod. The crossbar continues to move and drives the connecting rod to rotate. The rotation of the connecting rod drives the connecting shaft to rotate. The rotation of the connecting shaft drives the actuating plate to rotate. The rotation of the actuating plate can move the plastic, preventing the plastic from accumulating and causing smaller plastics to be unable to pass through the screen into the discharge chute, thereby affecting the subsequent processes. At the same time, the rotation of the connecting rod drives the connecting rod to move.

[0014] (3) In this invention, when the baffle moves upward, it drives the bent plate to move. The bent plate moves to contact the bottom of the screen and continues to move to contact the protrusion. The bent plate hits the screen, causing the screen to vibrate and improving the screening efficiency of plastic. At the same time, the baffle moves upward, driving the bent rod to move. The bent rod moves to contact the inclined surface of the inclined block and continues to move, causing the bent rod to rotate. The bent rod continues to move until it no longer contacts the inclined block and the bent rod is reset by the influence of the elastic force. The bent rod hits the discharge chute, causing the discharge chute to vibrate and preventing small plastics from remaining on the discharge chute. The bent rod continues to move and contacts the swing plate. The movement of the bent rod drives the swing plate to rotate. The rotation of the swing plate drives the brush to rotate. The rotating brush fits the bottom of the screen and cleans the mesh of the screen, preventing the mesh from being blocked and reducing the screening efficiency. Attached Figure Description

By setting the fixing device, the plastic on the conveying device 1 is smoothed to prevent the plastic from accumulating and affecting the working efficiency of the conveying device 1, and the plastic is fixed in the middle position of the conveying device 1.

[0019] The rotating block 405 contacts the moving plate 409, and the short rod 406 contacts the rotating plate 408. A spring is fixedly installed between the moving plate 409 and the fixed plate 402. By setting the spring, the moving plate 409 can be reset by the elastic force of the spring. The plastic on the conveying device 1 is smoothed by the contact between the short rod 406 and the rotating plate 408.

[0020] The side of the movable plate 409 closest to the L-shaped plate 411 and the long plate 412 is set as an inclined surface. The L-shaped plate 411 and the long plate 412 closest to the movable plate 409 are also set as inclined surfaces. The movement of the L-shaped plate 411 and the long plate 412 is achieved by setting the inclined surfaces, and the plastic is moved to the center.

[0021] The feeding device includes a gear shaft 501, a rack 502, a crossbar 503, a baffle 504, a connecting rod 505, a connecting rod 506, a connecting shaft 507, a actuating plate 508, a screen 509, and a curved plate 510. The screen 509 is fixedly installed inside the feeding box 3, and the curved plate 510 is fixedly installed inside the feeding box 3. The gear shaft 501 is rotatably installed on the right side of the feeding box 3, and the gear shaft 501 meshes with the toothed block on the top of the long plate 412. Slide grooves are provided on both sides of the feeding box 3, and the baffle 504 is slidably installed inside the slide grooves. The rack 502 is fixedly installed... Mounted on the right side of baffle 504, gear shaft 501 meshes with rack 502, crossbar 503 is fixedly mounted on the front of rack 502, connecting shaft 507 rotates through discharge box 3, connecting rod 506 is fixedly mounted on the end of connecting shaft 507 that protrudes from discharge box 3, connecting rod 505 is rotatably mounted on the right side of connecting rod 506, and actuating plate 508 is fixedly mounted on the circumferential surface of connecting shaft 507. By setting up a feeding device, the plastic is controlled to enter the intermittent conveying device 1, while simultaneously actuating the plastic on the surface of screen 509, thereby improving the efficiency of screening smaller plastics.

[0022] The end of the crossbar 503 near the connecting rod 506 is set as an arc surface. The connecting rod 505 contacts the connecting rod 506. Multiple connecting rods 506 are provided and all are connected to the connecting rod 505. The contact between the crossbar 503 and the connecting rod 506 causes the actuating plate 508 to rotate, thereby increasing the contact area between the plastic and the screen 509 and preventing small plastic pieces from falling into the conveying device 1, thus affecting subsequent processing.

[0023] The actuating plate 508 contacts the screen 509, and the baffle 504 contacts the screen 509. Intermittent feeding is achieved by setting the baffle 504 to avoid reducing work efficiency.

[0024] In this embodiment, during operation: Power is turned on, drive motor 2 starts, driving the conveyor device 1 to run. Simultaneously, servo motor 403 starts, driving shaft 404 to rotate. Shaft 404 rotates, driving short rod 406 to rotate. Short rod 406 rotates and contacts rotating plate 408. Short rod 406 continues to rotate, driving rotating plate 408 to rotate. Rotating plate 408 can smooth the raw material on conveyor device 1. Simultaneously, shaft 404 rotates, driving rotating block 405 to rotate. Rotating block 405 rotates and contacts moving plate 409. Rotating block 405 continues to rotate, causing moving plate 409 to move. Moving plate 409 causes its inclined surface to contact L-shaped plate 411 and long plate 412, thus making the L-shaped plate... The L-shaped plate 411 moves, which in turn drives the inclined plate 414 to move. When the inclined plate 414 moves to a point where it is no longer in contact with the fixed rod 410, it rotates under the influence of the torsion spring. When the rotating block 405 continues to rotate and no longer contacts the moving plate 409, the L-shaped plate 411 resets under the influence of the spring force. The reset of the L-shaped plate 411 causes the inclined plate 414 to contact the fixed rod 410. The continued reset of the L-shaped plate 411 causes the inclined plate 414 to rotate under the influence of the fixed rod 410, pushing the plastic at the edge of the conveying device 1 to the middle position, thus fixing the plastic in the middle position of the conveying device 1. At the same time, when the moving plate 409 moves, the inclined surface of the moving plate 409 contacts the L-shaped plate 411 and the long plate 412, causing the long plate 412 to move.

[0025] When the plastic enters the feeding box 3, it falls onto the surface of the screen 509. Due to the movement of the long plate 412, the gear shaft 501 that meshes with the toothed block at the top of the long plate 412 rotates. The rotation of the gear shaft 501 drives the rack 502 to move. The movement of the rack 502 drives the baffle 504 to move. At the same time, the movement of the rack 502 drives the crossbar 503 to move. The crossbar 503 moves and contacts the connecting rod 506. The crossbar 503 continues to move and drives the connecting rod 506 to rotate. The rotation of the connecting rod 506 drives the connecting shaft 507 to rotate. The rotation of the connecting shaft 507 drives the actuating plate 508 to rotate. At the same time, the rotation of the connecting rod 506 drives the connecting rod 505 to move.

By setting up the discharge device, the smaller plastics that have been screened out are discharged, preventing the smaller plastics from remaining inside the discharge trough 601.

[0027] The bent rod 604 contacts the swing plate 607. A second spring is fixedly installed between the swing plate 607 and the feeding box 3. The contact between the bent rod 604 and the swing plate 607 causes the brush 608 to contact the screen 509 and clean the mesh of the screen 509 to avoid clogging and reduce work efficiency.

[0028] In this embodiment, when the baffle 504 moves upward, it drives the bent plate 605 to move. The bent plate 605 moves until it contacts the bottom of the screen 509. The bent plate 605 continues to move and contacts the protrusion 606. The bent plate 605 impacts the screen 509. At the same time, the baffle 504 moves upward and drives the bent rod 604 to move. The bent rod 604 moves until it contacts the inclined surface of the inclined block 603. The bent rod 604 continues to move and rotates. The bent rod 604 continues to move until it no longer contacts the inclined block 603. The bent rod 604 is reset by the elastic force and impacts the discharge chute 601. The bent rod 604 continues to move and contacts the swing plate 607. The movement of the bent rod 604 drives the swing plate 607 to rotate. The rotation of the swing plate 607 drives the brush 608 to rotate. The brush 608 rotates and comes into contact with the bottom of the screen 509.
