Description

Technical Field

[0001] This utility model relates to the field of segmentation mechanisms, specifically a symmetrical ratchet linkage automatic segmentation mechanism. Background Technology

[0002] In current industrial production, common sheet material separation devices mainly include vibratory feeders and friction wheel separating mechanisms. Vibratory feeders use the inertia generated by vibration and track design to arrange randomly stacked sheet materials in an orderly manner and separate them one by one. Friction wheel separating mechanisms rely on the friction between the friction wheel and the sheet material, combined with a specific speed difference, to achieve sheet transportation. These devices usually rely on sensors or electronic control systems to monitor and control the separation action in real time, thereby completing the transportation and separation of sheet materials.

[0003] The working process of the sheet material separation device is essentially to precisely separate and orderly transport sheet materials. Starting from the initial stacked state, through the movement of the mechanical structure, the transmission of power, and the feedback adjustment of the sensors, the sheet materials are gradually separated into individual pieces and transported to the designated position at a predetermined trajectory and speed to meet the needs of subsequent processing or assembly.

[0004] However, in actual operation, existing separation devices are highly susceptible to environmental interference in industrial settings with dust and large temperature and humidity variations due to the high requirements of the electronic control components. This can lead to false triggering of sensors and the simultaneous falling of multiple sheet-like materials, severely impacting production efficiency and product quality. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a symmetrical ratchet linkage automatic sheet-separating mechanism to solve the technical problem that existing separation devices may experience sensor malfunctions due to environmental interference, resulting in multiple sheet materials falling off simultaneously.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a symmetrical ratchet-linked automatic slitting mechanism, comprising a frame, wherein multiple sets of products are arranged inside the frame and are vertically stacked together, and separation components are provided on both sides of each product, each separation component including a rotating rod, two sets of impellers are installed at both ends of the outer wall of the rotating rod, and multiple sets of blades are fixed to the outer wall of the impellers, a ratchet is fixed to the outer wall of the rotating rod, a limit component is connected to one side of the ratchet, the limit component includes a pawl, a drive plate is connected to one side of the pawl, a connecting plate is installed at the end of the drive plate, a trigger block is provided at the bottom of the connecting plate, and a push plate is installed at the bottom of the frame.

[0007] By adopting the above technical solution, the problem of multiple sheet materials falling simultaneously due to false triggering of sensors caused by environmental interference in existing separation devices is solved. During the movement of the push plate, the push plate pushes the trigger block, causing the trigger block to move the pawl out of the slot on one side of the ratchet. Due to the weight of the product, the impeller rotates at a certain angle, causing the product at the bottom to move to the bottom of the impeller and fall above the roller. When the push plate is not in contact with the trigger block, the large weight of the trigger block causes the trigger block to move the pawl back into the slot on one side of the ratchet, preventing the ratchet from rotating. The four sets of impellers support and fix the products that have not fallen. Thus, this device can achieve product separation without the need for sensors or electronic control systems by using the physical limit of the ratchet and pawl and gravity drive.

[0008] The present invention is further configured such that a first rotating column is provided on one side of the bottom of the pawl, and a first fixing block is installed at the end of the first rotating column; a second rotating column is provided on one side of the connecting plate, and a second fixing block is installed at the end of the second rotating column.

[0009] Preferably, when the push plate presses and pushes the trigger block, the trigger block drives the connecting plate to rotate around the second rotating column as the center. The connecting plate drives the pawl to rotate around the first rotating column as the center through the drive plate, so that the pawl disengages from the slot on one side of the ratchet.

[0010] The present invention is further configured such that the weight of the trigger block is greater than the weight of the pawl.

[0011] Preferably, when the push plate no longer presses against the contact block, the large gravity of the trigger block causes the trigger block to drive the connecting plate to rotate and reset to a vertical state, which in turn enables the connecting plate to drive the pawl to rotate and reset.

[0012] The present invention is further configured such that one side of the ratchet is provided with multiple sets of slots, and the total number of slots is equal to the total number of blades.

[0013] Preferably, when the pawl is engaged in the slot on one side of the ratchet, the pawl can limit and fix the ratchet, preventing the four sets of impellers from rotating, thereby enabling the blades to support and fix the product that has not fallen.

[0014] The present invention is further configured such that a slider is fixed at the bottom of the push plate, a lead screw runs through the inside of the slider, and a servo motor is installed at the end of the lead screw.

[0015] Preferably, the servo motor drives the slider to move via a lead screw, and the slider and the lead screw are connected by a thread.

[0016] The present invention is further configured such that limit blocks are provided on both sides of the slider, and a groove is provided at the bottom of the frame.

[0017] Preferably, since the lead screw and the slider are connected by a thread, the slider will also rotate when the lead screw rotates. Therefore, limit blocks are installed on both sides of the slider, and the ends of the limit blocks are located in the grooves of the frame, so that the slider will not rotate when the lead screw drives the slider.

[0018] The present invention is further configured such that multiple sets of rollers are installed at the bottom of the frame, and the horizontal height of the top outer wall of the rollers is equal to the bottom height of the push plate.

[0019] Preferably, the roller mounting configuration reduces friction between the product and the frame, thereby reducing wear and tear on the product as it moves within the frame.

[0020] The present invention is further configured such that the trigger block is located on one side of the bottom of the product.

[0021] Preferably, when the push plate contacts the trigger block, the push plate has moved to one side of the bottom of the product. When the product falls above the roller, the product will not fall to the top of the push plate. And when the impeller rotates 30 degrees clockwise, the push plate pushes the product to one side.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem of multiple sheet materials falling simultaneously due to false triggering of sensors caused by environmental interference in existing separation devices by setting up a servo motor, lead screw, push plate, separation component, and limiting component. During the movement of the push plate, the push plate pushes the trigger block, causing the trigger block to move the pawl out of the slot on one side of the ratchet. Due to the weight of the product, the impeller rotates 30 degrees clockwise, causing the product at the bottom to move to the bottom of the impeller and fall above the roller. When the push plate is not in contact with the trigger block, due to the large weight of the trigger block, the trigger block causes the pawl to re-enter the slot on one side of the ratchet, and the ratchet cannot rotate. The four sets of impellers support and fix the products that have not fallen. Thus, this device can achieve product separation without the need for sensors or electronic control systems by setting up a servo motor, lead screw, push plate, separation component, and limiting component.

[0024] 2. This utility model, by setting up a push plate, slider, slide groove, limit block and roller, when the product falls to the position above the roller, the servo motor drives the sliding movement again through the lead screw, the push plate pushes the product that has fallen to the top of the roller, and finally pushes the product out of the frame, thus completing the product separation process. In addition, the installation of the roller reduces the friction between the product and the frame, thereby reducing the wear and tear of the product moving inside the frame.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Please see Figure 1 — Figure 5The device includes a frame 1, inside which multiple sets of products 2 are vertically stacked. Separation components are located on both sides of each product 2. Each separation component includes a rotating rod 502. Two sets of impellers 5 are mounted on the outer ends of the rotating rod 502. Multiple sets of blades 501 are fixed to the outer walls of the impellers 5. A ratchet 7 is fixed to the outer wall of the rotating rod 502. A limit component is connected to one side of the ratchet 7. The limit component includes a pawl 6. A drive plate 603 is connected to one side of the pawl 6. A connecting plate 604 is mounted at the end of the drive plate 603. A trigger block 605 is located at the bottom of the connecting plate 604. A push plate 3 is mounted at the bottom of the frame 1. This design solves the problem of multiple sheet materials falling simultaneously due to false triggering of sensors caused by environmental interference in existing separation devices. The problem is that during the movement of the push plate 3, the push plate 3 will push the trigger block 605, causing the trigger block 605 to drive the pawl 6 to move out of the slot 701 on the side of the ratchet 7. Due to the gravity of the product 2, the impeller 5 will rotate at a certain angle, causing the product 2 located at the bottom to move to the bottom of the impeller 5 and fall above the roller 4. When the push plate 3 is not in contact with the trigger block 605, due to the large weight of the trigger block 605, the trigger block 605 will drive the pawl 6 to get back into the slot 701 on the side of the ratchet 7. The ratchet 7 cannot rotate. The four sets of impellers 5 support and fix the product 2 that has not fallen. Thus, this device can separate the product 2 without the need for sensors or electronic control systems by using the physical limit and gravity drive of the ratchet 7 and pawl 6.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 A first rotating post 601 is provided on one side of the bottom of the pawl 6, and a first fixing block 602 is installed at the end of the first rotating post 601. A second rotating post 606 is provided on one side of the connecting plate 604, and a second fixing block 607 is installed at the end of the second rotating post 606. When the push plate 3 presses and pushes the trigger block 605, the trigger block 605 drives the connecting plate 604 to rotate around the second rotating post 606 as the center. The connecting plate 604 drives the pawl 6 to rotate around the first rotating post 601 as the center through the drive plate 603, so that the pawl 6 disengages from the slot 701 on one side of the ratchet 7.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The weight of the trigger block 605 is greater than the weight of the pawl 6. When the push plate 3 no longer presses the contact block 605, the greater gravity of the trigger block 605 causes the connecting plate 604 to rotate and reset to a vertical state, which in turn enables the connecting plate 604 to rotate and reset the pawl 6.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 4The ratchet 7 has multiple slots 701 on one side, and the total number of slots 701 is equal to the total number of blades 501. When the pawl 6 is engaged in the slot 701 on one side of the ratchet 7, the pawl 6 can limit and fix the ratchet 7, so that the four sets of impellers 5 cannot rotate, thereby enabling the blades 501 to support and fix the product 2 that has not fallen.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A slider 301 is fixed at the bottom of the push plate 3. A lead screw 302 passes through the inside of the slider 301. A servo motor 303 is installed at the end of the lead screw 302. The servo motor 303 drives the slider 301 to move through the lead screw 302. The slider 301 and the lead screw 302 are connected by threads.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 5 Limiting blocks 305 are provided on both sides of the slider 301, and a groove 304 is provided at the bottom of the frame 1. Since the lead screw 302 and the slider 301 are connected by a thread, the slider 301 will also rotate when the lead screw 302 rotates. Therefore, limiting blocks 305 are installed on both sides of the slider 301. The ends of the limiting blocks 305 are located in the groove 304 of the frame 1, so that the slider 301 will not rotate when the lead screw 302 drives the slider 301.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 Multiple sets of rollers 4 are installed at the bottom of the frame 1, and the horizontal height of the top outer wall of the rollers 4 is equal to the bottom height of the push plate 3. The installation of the rollers reduces the friction between the product and the frame, thereby reducing the wear and tear of the product as it moves inside the frame.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The trigger block 605 is located on one side of the bottom of the product 2. When the push plate 3 contacts the trigger block 605, the push plate 3 has moved to one side of the bottom of the product 2. When the product 2 falls above the roller 4, the product 2 will not fall to the top of the push plate 3. And when the impeller 5 rotates 30 degrees clockwise, the push plate 3 pushes the product 2 to one side.

[0042] In practical operation, multiple product sets 2 are stacked on top of frame 1. Four sets of impellers 5 on both sides of frame 1 support the product 2 at the lowest position through blades 501. When it is necessary to separate a product set 2, servo motor 303 drives slider 301 to move horizontally in a certain direction at the bottom of frame 1 through lead screw 302. Slider 301 drives push plate 3 to move synchronously. During the process of push plate 3 moving to one side of frame 1, push plate 3 will squeeze and push trigger block 605, so that trigger block 605 drives connecting plate 604 to rotate around second rotating column 606 as the center. Connecting plate 604 drives pawl 6 to rotate around first rotating column 601 through drive plate 603. When pawl 6 rotates, pawl 6 disengages from slot 701 on one side of ratchet 7, so that pawl 6 releases the limiting fixation of ratchet 7. Due to the gravity of product 2 This causes the impeller 5 to rotate slowly, causing the bottom product 2 to fall onto the top of the roller 4. Simultaneously, the blade 501 supports and blocks the product 2 above the fallen product 2. The servo motor 303 drives the sliding 301 to move again via the lead screw 302. The push plate 3 pushes the product 2 that has fallen onto the top of the roller 4. When the push plate 3 is not in contact with the trigger block 605, due to the large mass of the trigger block 605, the trigger block 605 drives the connecting plate 604 to rotate into a vertical state. The connecting plate 604 drives the pawl 6 to rotate and reset via the drive plate 603, causing the pawl 6 to re-engage in the slot 701 on one side of the ratchet 7. The ratchet 7 cannot rotate due to the obstruction of the pawl 6. The blade 501 supports and fixes the product 2 that has not fallen. Finally, the product 2 is pushed and separated from the inside of the frame 1, thus completing the separation process of the product 2.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
