Description

Technical Field

[0001] This utility model relates to the field of material storage technology for rubber roller grinding machines, specifically an adjustable material storage box for rubber roller grinding machines. Background Technology

[0002] Rubber rollers are important components in the textile industry. After a period of use, the circumferential surface of the rubber roller body becomes rough, which affects its textile performance. It is necessary to use a rubber roller grinding machine to grind the circumference of the rubber roller body to make it smooth. After the rubber roller is ground, it needs to be collected and stored in a material box, which is usually located at the discharge port of the rubber roller grinding machine.

[0003] A storage bin for polyurethane rollers, application number 202421409312.3, includes a positioning frame, a sliding plate, and an anti-jamming mechanism. The positioning frame is rectangular, with two frames spaced apart. Multiple fixing posts are positioned between the two side edges of the two positioning frames. Sliding plates are symmetrically fixed to the fixing posts. An "S"-shaped track is provided on the sliding plate between the fixing posts. An anti-jamming mechanism is installed in the positioning frame corresponding to the sliding plate, and the anti-jamming mechanism is intermittently connected to the sliding plate. This storage bin for polyurethane rollers effectively solves the problem of roller jamming in existing bins, which leads to uneven material feeding and affects normal storage.

[0004] This technical solution avoids jamming by tapping. Although the swing arm is wrapped in flexible rubber, the rubber is prone to hardening and cracking after long-term tapping. Moreover, the hardness of pure rubber is relatively high, and the cushioning effect is generally poor. Long-term tapping can easily cause deformation of the skateboard and swing arm, increasing the possibility of jamming. Furthermore, the vibration during tapping can cause the normally normal rubber roller to be misaligned and jammed, increasing the resistance when the rubber roller moves out. This causes the rubber roller to continuously alternate between jamming and sliding states when sliding in the skateboard, resulting in wear between the side of the rubber roller and the skateboard. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an adjustable storage box for a rubber roller grinding machine to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable storage box for a rubber roller grinding machine, comprising a box body, a motor mounted on one side of the outer surface of the box body, and a reducer connected to the output end of the motor; two bidirectional lead screws and slide rails are provided on both sides inside the box body, and one bidirectional lead screw is connected to the output end of the reducer; synchronous pulleys are connected to the back of both bidirectional lead screws, and a synchronous belt is connected between the two synchronous pulleys; two material racks are respectively connected to the outside of the two bidirectional lead screws through lead screw nuts, and sliders are fixed on both sides of the two material racks; storage grooves are opened on the outer surface of both material racks, and resistance reducing plates are provided inside the storage grooves; electric cylinders are installed on the lower part of the outer surface and the lower part of the back of the box body, and a stop is connected to the output end of the electric cylinder.

[0007] By adopting the above technical solution, the height and width of the storage tank are greater than the diameter of the rubber roller body, allowing the rubber roller body to move in a rolling manner, reducing wear on the rubber roller body. Furthermore, the friction-reducing plate made of polytetrafluoroethylene (PTFE) reduces the friction between the rubber roller body and the storage tank and material rack, reducing the occurrence of jamming caused by friction when the skewed rear end face of the rubber roller body contacts the surface of the material rack, allowing the rubber roller to move more smoothly. In case of jamming, the motor output drives a double-acting screw to rotate via a reducer, and then two double-acting screws rotate synchronously via a synchronous pulley and synchronous belt, causing the two material racks to move towards each other or in opposite directions. During this process, the material racks are guided by slide rails and sliders, and the resistance to the movement of the material racks is reduced. The diameter between the two material racks is shortened to reduce the skewed rear end face. The side of the obstructed rubber roller no longer contacts the side wall of the material rack, thus ending the jamming and allowing the rubber roller to continue rolling. Afterwards, the other two material racks are restored to their original spacing to ensure normal conveying. The spacing between the two material racks can be adjusted by driving the two material racks with a bidirectional screw to accommodate rubber rollers of different lengths. When unloading, for example, when two rubber roller bodies are stacked, one rubber roller body is located inside the baffle and the other rubber roller body is located on top of the baffle, after the electric cylinder is started, the output end drives the baffle to reciprocate once. This causes the rubber roller body located below to fall into the guide groove for discharge due to gravity, while the rubber roller located above is blocked by the baffle and cannot fall. This avoids the phenomenon of a large number of discharged rubber roller bodies getting stuck in the guide groove and the material picking basin. After the baffle is reset, the rubber roller body that was originally located above enters the baffle body under the influence of gravity.

[0008] Furthermore, the material rack is connected to a bidirectional lead screw threadedly via a lead screw nut, and the material rack is slidably connected to a slide rail via a slider.

[0009] By adopting the above technical solution, the motor output drives a bidirectional lead screw to rotate through a reducer, and then the two bidirectional lead screws rotate synchronously through a synchronous pulley and synchronous belt, thereby causing the two material racks to move towards each other or in opposite directions. During this process, the material racks are guided by slide rails and sliders, and the resistance to the movement of the material racks is reduced.

[0010] Furthermore, both the storage tank and the resistance-reducing plate are serpentine in shape, and the resistance-reducing plate is made of polytetrafluoroethylene material.

[0011] By adopting the above technical solution, the friction between the rubber roller body and the storage tank and material rack is reduced by the friction reduction plate made of polytetrafluoroethylene material. This reduces the phenomenon of jamming caused by friction when the skewed rear end face of the rubber roller body is attached to the surface of the material rack, allowing the rubber roller to move more smoothly.

[0012] Furthermore, the baffle is slidably connected to the box body and the material rack, respectively.

[0013] By adopting the above technical solution, during material feeding, for example, two rubber roller bodies are stacked, with one rubber roller body located inside the baffle and the other rubber roller body located on top of the baffle. After the electric cylinder is started, the output end drives the baffle to reciprocate once, causing the rubber roller body located below to fall into the guide groove for discharge due to gravity, while the rubber roller body located above is blocked by the baffle and cannot fall. This avoids the phenomenon of a large number of discharged rubber roller bodies getting stuck in the guide groove and the material picking basin. After the baffle is reset, the rubber roller body originally located above enters the baffle interior due to gravity.

[0014] Furthermore, a collection trough is provided on the top of the material rack, a guide trough is provided at the bottom inside the box, a material scooping basin is fixed at the bottom of one side of the box, and a rubber roller body is provided at the bottom inside the storage trough.

[0015] By adopting the above technical solution, after the rubber roller grinding machine finishes grinding the rubber roller body, it is unloaded and moved into the collection trough. The collection trough guides the rubber roller body to roll into the storage trough. The storage trough is serpentine, which allows the rubber roller body to continue to move down by gravity and facilitates the storage of multiple rubber roller bodies. During unloading, the rubber roller body falls into the guide trough due to gravity, and then rolls into the material collection basin due to gravity, making it easy for workers to take out the rubber roller body.

[0016] Furthermore, the main body of the rubber roller abuts against the stop frame.

[0017] By adopting the above technical solution, after the electric cylinder is started, the output end drives the baffle to reciprocate once, causing the lower rubber roller body to fall into the guide groove for discharge due to gravity, while the upper rubber roller is blocked by the baffle and cannot fall, thus avoiding the phenomenon of a large number of discharged rubber roller bodies getting stuck in the guide groove and the material picking basin.

[0018] Furthermore, the diameter of the main body of the rubber roller is smaller than the height and width of the storage tank.

[0019] By adopting the above technical solution, the height and width of the storage tank are greater than the diameter of the rubber roller body, so that the rubber roller body moves in a rolling manner, reducing the wear caused to the rubber roller body.

[0020] Furthermore, both the collection trough and the guide trough are sloped.

[0021] By adopting the above technical solution, the rubber roller body is guided to roll into the storage tank by the collection trough, and then guided to roll into the material collection basin by the guide trough.

[0022] Furthermore, a buffer pad is connected inside the guide groove, and the buffer pad is made of TPU material.

[0023] By adopting the above technical solution, the rubber roller body falling into the guide trough is cushioned by the buffer pad. The TPU buffer pad has good elasticity, which can effectively reduce the impact force when the rubber roller body falls, and can be used for a long time.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the configuration of a motor, reducer, and bidirectional lead screw, allows the output end of the motor to drive a bidirectional lead screw to rotate via the reducer after starting. Then, through the synchronous pulley and synchronous belt transmission, the two bidirectional lead screws rotate synchronously, thereby causing the two material racks to move towards each other or in opposite directions. Firstly, by shortening the diameter between the two material racks, the side of the skewed and stuck rubber roller no longer contacts the side wall of the material rack, thus ending the jamming and allowing the rubber roller to continue rolling. Afterward, the two material racks are restored to their original spacing to ensure normal conveying. Secondly, the adjustable spacing facilitates the adaptation to rubber rollers of different lengths; it easily solves the jamming problem and is easy to adapt to rubber rollers of different lengths.

[0026] 2. This utility model, through the setting of a storage tank and a drag-reducing plate, with the height and width of the storage tank being greater than the diameter of the rubber roller body, allows the rubber roller body to move in a rolling manner, reducing wear on the rubber roller body. Furthermore, the drag-reducing plate, made of polytetrafluoroethylene (PTFE), reduces friction between the rubber roller body and the storage tank and the material rack, minimizing the friction and jamming caused by the rubber roller body's skewed rear end face contacting the material rack surface. This allows the rubber roller to move more smoothly and steadily, reducing jamming.

[0027] 3. This utility model, through the setting of an electric cylinder and a baffle, allows for material feeding. For example, when two rubber roller bodies are stacked, one rubber roller body is located inside the baffle, and the other rubber roller body is located on top of the baffle. After the electric cylinder is started, the output end drives the baffle to reciprocate once. This causes the rubber roller body located below to fall into the guide groove for discharge due to gravity, while the rubber roller body located above is blocked by the baffle and cannot fall. This avoids the phenomenon of a large number of discharged rubber roller bodies getting stuck in the guide groove and the material collection basin. After the baffle is reset, the rubber roller body originally located above will enter the baffle body under the influence of gravity. Each reciprocating motion of the baffle will only discharge one rubber roller body, which is convenient for quantitative feeding and avoids material blockage. Attached Figure Description

Detailed Implementation

[0034] 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.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] An adjustable storage bin for a rubber roller grinding machine, such as Figures 1-5 As shown, the device includes a housing 1. A motor 9 is mounted on one side of the outer surface of the housing 1. A reducer 10 is connected to the output end of the motor 9. Two bidirectional lead screws 11 and slide rails 15 are installed on both sides of the interior of the housing 1. One bidirectional lead screw 11 is connected to the output end of the reducer 10. Synchronous pulleys 13 are connected to the back of both bidirectional lead screws 11, and a synchronous belt 14 connects the two synchronous pulleys 13. Two material racks 2 are connected to the outside of the two bidirectional lead screws 11 through lead screw nuts 12. The material racks 2 are threadedly connected to the bidirectional lead screws 11 through the lead screw nuts 12. Slider blocks 16 are fixed on both sides of the two material racks 2. The material racks 2 are slidably connected to the slide rails 15 through the sliders 16. When jammed, the output end of the motor 9... A reducer 10 drives a bidirectional lead screw 11 to rotate, and then a synchronous pulley 13 and a synchronous belt 14 drive two bidirectional lead screws 11 to rotate synchronously, thereby causing the two material racks 2 to move towards each other or in opposite directions. During this process, the slide rail 15 and the slider 16 guide the material racks 2 and reduce the resistance to their movement. By shortening the diameter between the two material racks 2, the side of the skewed and stuck rubber roller body 5 no longer contacts the side wall of the material rack 2, thus ending the jamming and allowing the rubber roller to continue rolling. Afterward, the other two material racks 2 are restored to their original spacing to ensure normal conveying. The distance between the two material racks 2 can be adjusted by driving the bidirectional lead screw 11 to accommodate rubber rollers of different lengths.

[0038] Both material racks 2 have storage grooves 4 on their outer surfaces. The diameter of the rubber roller body 5 is smaller than the height and width of the storage groove 4. The storage groove 4 is equipped with a resistance reducing plate 8. Both the storage groove 4 and the resistance reducing plate 8 are serpentine. The resistance reducing plate 8 is made of polytetrafluoroethylene. The height and width of the storage groove 4 are larger than the diameter of the rubber roller body 5, so that the rubber roller body 5 moves in a rolling manner, reducing the wear caused to the rubber roller body 5. In addition, the resistance reducing plate 8 made of polytetrafluoroethylene reduces the friction between the rubber roller body 5 and the storage groove 4 and the material rack 2, reducing the phenomenon of sticking caused by friction when the skewed rear end face of the rubber roller body 5 is in contact with the surface of the material rack 2, so that the rubber roller can move more smoothly.

[0039] Electric cylinders 18 are installed on the lower outer surface and the lower back of the housing 1. The output end of the electric cylinder 18 is connected to a baffle 19. The baffle 19 is slidably connected to the housing 1 and the material rack 2 respectively. The rubber roller body 5 abuts against the baffle 19. When feeding, for example, two rubber roller bodies 5 are stacked, one rubber roller body 5 is located inside the baffle 19, and the other rubber roller body 5 is located on top of the baffle 19. After the electric cylinder 18 is started, the output end drives the baffle 19 to reciprocate once. This causes the rubber roller body 5 located below to fall into the guide groove 6 for discharge due to gravity, while the rubber roller located above is blocked by the baffle 19 and cannot fall. This avoids the phenomenon of a large number of discharged rubber roller bodies 5 getting stuck in the guide groove 6 and the material picking basin 7. After the baffle 19 is reset, the rubber roller body 5 that was originally located above enters the baffle 19 due to gravity.

[0040] See Figure 1 , Figure 2 , Figure 3 and Figure 5 In the above embodiment, a collection groove 3 is provided on the top of the material rack 2, and a guide groove 6 is provided at the bottom inside the box 1. Both the collection groove 3 and the guide groove 6 are sloping. A material retrieval basin 7 is fixed at the bottom of one side of the box 1, and a rubber roller body 5 is provided at the bottom inside the storage tank 4. After the rubber roller grinding machine grinds the rubber roller body 5, it is unloaded, so that the rubber roller body 5 moves into the collection groove 3. Guided by the collection groove 3, the rubber roller body 5 rolls into the storage tank 4. The storage tank 4 is serpentine, so that the rubber roller body 5 can continue to move down by gravity and facilitates the storage of multiple rubber roller bodies 5. When unloading, the rubber roller body 5 falls into the guide groove 6 due to gravity. Then, the rubber roller body 5 rolls into the material retrieval basin 7 due to gravity, which makes it easy for the staff to take out the rubber roller body 5.

[0041] Example 2:

[0042] Based on the above embodiment 1, in order to reduce the damage caused by the falling of the glue-sweeping roller body 5, the following settings are now implemented.

[0043] See Figure 2 and Figure 3In the above embodiment, a buffer pad 17 is connected inside the guide groove 6. The buffer pad 17 is made of TPU material. The rubber roller body 5 that falls into the guide groove is buffered by the buffer pad 17. The TPU buffer pad 17 has good elasticity and can effectively reduce the impact force when the rubber roller body 5 falls, and can be used for a long time.

[0044] The implementation principle of this utility model is as follows: First, after the rubber roller grinding machine finishes grinding the rubber roller body 5, it is unloaded so that the rubber roller body 5 moves into the collection groove 3. The rubber roller body 5 is guided by the collection groove 3 to roll into the storage groove 4. The storage groove 4 is serpentine so that the rubber roller body 5 can continue to move down by gravity and facilitates the storage of multiple rubber roller bodies 5.

[0045] The height and width of the storage tank 4 are greater than the diameter of the rubber roller body 5, so that the rubber roller body 5 moves in a rolling manner, reducing the wear caused to the rubber roller body 5. In addition, the friction reduction plate 8 made of polytetrafluoroethylene material reduces the friction between the rubber roller body 5 and the storage tank 4 and the material rack 2, reducing the phenomenon of jamming caused by friction when the skewed rear end face of the rubber roller body 5 is attached to the surface of the material rack 2, so that the rubber roller can move more smoothly.

[0046] When jamming occurs, the output of motor 9 drives a bidirectional lead screw 11 to rotate through reducer 10. Then, through synchronous pulley 13 and synchronous belt 14, the two bidirectional lead screws 11 rotate synchronously, causing the two material racks 2 to move towards each other or in opposite directions. During this process, the material racks 2 are guided by slide rail 15 and slider 16, and the resistance to the movement of the material racks 2 is reduced. By shortening the diameter between the two material racks 2, the side of the skewed and jammed rubber roller body 5 no longer contacts the side wall of the material rack 2, thus ending the jamming and allowing the rubber roller to continue rolling. Afterward, the other two material racks 2 are restored to their original spacing to ensure normal conveying. The distance between the two material racks 2 can be adjusted by driving the bidirectional lead screw 11 to accommodate rubber rollers of different lengths.

[0047] During material feeding, for example, two rubber roller bodies 5 are stacked, with one rubber roller body 5 located inside the baffle 19 and the other rubber roller body 5 located on top of the baffle 19. After the electric cylinder 18 is started, the output end drives the baffle 19 to reciprocate once, causing the rubber roller body 5 located below to fall into the guide groove 6 for discharge due to gravity, while the rubber roller located above is blocked by the baffle 19 and cannot fall, thus avoiding the phenomenon of a large number of discharged rubber roller bodies 5 getting stuck in the guide groove 6 and the material collection basin 7. After the baffle 19 is reset, the rubber roller body 5 originally located above enters the baffle 19 under the influence of gravity. The rubber roller body 5 that falls into the guide groove is cushioned by the buffer pad 17. The TPU buffer pad 17 has good elasticity and can effectively reduce the impact force when the rubber roller body 5 falls, and can be used for a long time. Afterwards, the rubber roller body 5 rolls into the material collection basin 7 under the influence of gravity, making it easy for the staff to remove the rubber roller body 5.
