Description

Technical Field

[0001] The invention relates to the technical field of screw rod packaging, in particular to a screw rod packaging device. Background Art

[0002] There are several ways to pack the screw after processing in the prior art. One of them is to put a long cylindrical plastic film on the screw and then wrap it with waterproof tape for secondary protection. When wrapping the waterproof tape, the waterproof tape needs to be gradually tilted after wrapping the head end, so that it can be gradually wrapped from the head end of the screw to the tail end and save the waterproof tape.

[0003] The packaging work is mostly done manually, and the film covering and tape wrapping need to be done back and forth. It is difficult for novices to control the tilt angle of the tape. If the tilt angle is too large, the plastic film will be exposed, making the waterproof effect worse. If the tilt angle is too small, the tapes will overlap and cause waste, and slowing down the speed will reduce production capacity. Summary of the invention

[0004] Based on this, it is necessary to provide a screw rod packaging equipment to address the above technical problems.

[0005] In order to achieve the above object, the present invention provides a screw rod packaging device, comprising: A frame, with through holes on both sides for the screw rods to pass through, and a moving mechanism at the bottom of the frame; A through slot is arranged on the frame, the through slot passes through the through hole, a plurality of film rings are movably placed in the through slot, a plastic sealing soft film is stacked on the film rings, a limiting mechanism is arranged on the inner wall of the through slot, and an output end of the limiting mechanism abuts against the plastic sealing soft film; A rotating frame is rotatably mounted on the frame and can be concentrically rotated around the through hole. A rotating frame is rotatably mounted on the rotating frame. A rotating driving mechanism is mounted on the rotating frame. The rotating driving mechanism has two output ends, one of which is transmission-connected to the rotating frame. A rotating telescopic mechanism is mounted on the rotating frame. The other output end of the rotating driving mechanism is transmission-connected to the rotating telescopic mechanism so that the rotating telescopic mechanism is driven to telescope. A universal joint is mounted on one end of the rotating telescopic mechanism away from the rotating driving mechanism. A clamping mechanism is hinged on the rotating frame. The universal joint is rotationally connected to a side of the clamping mechanism away from the hinged end. The fixing frame is fixedly installed on a wall or the ground, a support rod is rotatably installed on the fixing frame, a spring is installed on the fixing frame, and an output end of the spring is connected to the support rod.

[0006] By adopting the above technical scheme, the frame can be moved under the drive of the moving mechanism, so that the lead screw to be packaged placed on the support rod can pass through the through hole on the frame. When passing through, due to the abutment of the limiting mechanism on the film ring and the plastic sealing soft film on it, the plastic sealing soft film can be gradually and evenly brought out from the film ring by the lead screw for coating work, thereby avoiding the plastic sealing film from being broken by large pulling force; the limiting mechanism can be abutted by a spring or extruded by an electric cylinder; a plastic thin pad can be added to the end of the plastic sealing soft film abutted by the lead screw head, thereby further avoiding the breakage of the plastic sealing soft film end; when the frame passes through a support rod, it can abut against it and rotate it back to a position close to the fixed frame. After the frame moves away, the spring can drive the support rod to reset and support the lead screw again. The number of fixed frames should be three or more, and the spring here is preferably a curved spring. The clamping mechanism can be any clamp in the prior art that can clamp the waterproof tape and does not hinder the rotation of the waterproof tape; after the waterproof tape drives the plastic sealing soft film to move into the frame at one end of the screw rod, one end of the waterproof tape installed at the clamping mechanism can be wound around the screw rod, and then the rotating frame is driven to rotate. After the rotating frame rotates several times, that is, the head end of the screw rod is vertically wound, the rotary drive mechanism starts to drive the rotating telescopic mechanism to rotate, so that the rotating telescopic mechanism can be extended, so that the clamping mechanism can be deflected along the hinge with the rotating frame, that is, the tilt angle is adjusted, so that the rotary drive mechanism can be driven by the rotating telescopic mechanism. The movable mechanism drives the rotating telescopic mechanism to rotate several times and extend the specified distance, so that the waterproof tape can be tilted to a fixed angle for winding. When it is wound to the end of the screw rod, the clamping mechanism is reset to continue vertical winding, so that the film can be wrapped and wound at the same time, and the problems of rupture of the plastic sealing soft film and leakage and waste of tape winding are avoided; when the plastic sealing film is wrapped to the end of the screw rod, the plastic sealing film on the film ring gradually becomes less, so that the pressure of the limiting mechanism on it gradually decreases, and finally at the end of the film wrapping, the screw rod can drive the film wrapping ring to slide out of the through hole, and then the waterproof tape can wrap the film wrapping ring together with the screw rod. The rotary drive mechanism can be two motors or a dual-axis motor with two output ends that rotate asynchronously. The rotary telescopic mechanism can be a sleeve and sleeve rod structure. The sleeve rod is threadedly connected to the rotating frame to achieve telescopic movement during rotation, or it can be two gears with larger thicknesses that are meshed. When one of the gears rotates, it can drive the other gear and the screw threadedly connected to the rotating frame to rotate and move downward, and the thicker gear allows the two gears to always be meshed; the output end of the rotary drive mechanism is transmission-connected to the rotating frame, so that when the rotating frame is fixed, it can drive the rotating frame to rotate relative to the rotating frame by degrees, so that the screw rods that pass through any through hole on both sides of the frame can be packaged; when the film ring is brought out of the through slot, the upper film ring can automatically fall off, thereby facilitating the packaging of the next screw rod.

[0007] Optionally, the moving mechanism includes a drive shaft rotatably mounted on the frame. A second rotary drive device is mounted on the frame, and the output end of the second rotary drive device is in transmission connection with the drive shaft. An adjusting gear is rotatably mounted on the frame. The adjusting gear and the drive shaft are in transmission connection through a transmission component. A lifting frame is slidably clamped in the through groove. A rack is mounted at the lower end of the lifting frame. The adjusting gear is meshed with the rack. The lifting frame and the limiting mechanism cooperate to jointly limit and clamp the film sleeve ring. A second spring is mounted in the through groove, and the output end of the second spring is connected to the lifting frame. An opening for the lead screw to pass through is provided on the lifting frame.

[0008] By adopting the above technical solution, when the moving mechanism drives the frame to move in different directions, that is, the second rotary drive device drives the drive shaft to rotate in different directions, thereby driving the adjusting gear to rotate through transmission. Due to the meshing of the adjusting gear and the rack on the lifting frame, the lifting frame at the front end of the frame's traveling direction can be driven to descend, so that the film sleeve ring above the lifting frame can fall and be jointly limited by the lifting frame and the limiting mechanism. The adjusting gear at the rear end of the frame's traveling direction can drive the lifting frame to rise, so that when the lead screw passes through here, it can pass through the opening on the lifting frame without secondary reverse film covering; there is a certain gap between the lifting frame and the rack, so that when the lifting frame is driven to descend to the lowest position, the adjusting gear will continuously collide with the top of the rack and will not cause the lifting frame to continue to descend under the support of the spring. The same is true for the rear end, and the adjusting gear will continuously collide with the bottom of the rack; the second spring enables the lifting frame slidably clamped in the chute to be reset; by increasing the number of teeth of the adjusting gear, when the lifting frame is driven to be reset by the second spring during the working process, the shaking amplitude of the lifting frame is reduced, thus avoiding affecting the packing work. Therefore, after the frame finishes packing the lead screw, there is no need to reset, and it can directly move back for packing after the staff place another set of lead screws.

[0009] Optionally, the moving mechanism further includes a plurality of traveling wheels, and the plurality of traveling wheels are all in transmission connection with the drive shaft through a transmission component.

[0010] By adopting the above technical solution, through the transmission connection of the transmission component, when the drive shaft rotates, it can drive a plurality of traveling wheels to rotate, so that the entire frame can move forward or backward.

[0011] Optionally, the limiting mechanism includes a clamping groove provided on both sides of the inner wall of the through groove. A clamping block is slidably clamped in the clamping groove. A third spring is mounted in the clamping groove, and the output end of the third spring is connected to the clamping groove. The clamping block is provided with a chamfer.

[0012] By adopting the above technical solution, when the lifting frame moves upward, the clamping block can be extruded, so that the third spring is compressed and it retracts into the clamping groove. When the machine frame is driven to move back and forth, since the film sleeving ring is placed on the lifting frame, due to the chamfer setting of the clamping block, the film sleeving ring can smoothly pass through the clamping block without being limited above the through hole, thus realizing the common limiting and clamping of the lifting frame and the limiting mechanism on the film sleeving ring.

[0013] Optionally, a ring groove is provided on the machine frame, a clamping post is installed on the rotating frame, the clamping post is slidably clamped in the ring groove, a toothed ring is rotatably installed on the machine frame, the toothed ring is connected to the rotating frame, a third rotating driving device is installed on the machine frame, and an output end of the third rotating driving device is installed with a rotating gear, and the rotating gear is meshed and connected with the toothed ring.

[0014] By adopting the above technical solution, through the sliding clamping of the clamping posts on the rotating frame in the ring grooves on both sides of the machine frame, the rotating frame is driven to rotate stably on the machine frame; the third rotating driving device drives the rotating gear to rotate, and through the meshing of the rotating gear and the toothed ring, the toothed ring can drive the rotating frame to make a circumferential rotation around the through hole.

[0015] Optionally, the rotating driving mechanism is preferably a double-shaft motor; the rotating and telescoping mechanism includes a small gear, an output end of the double-shaft motor is in transmission connection with the small gear, a telescopic screw rod is threadedly connected to the rotating frame, a large gear is installed on the telescopic screw rod, the large gear is meshed and connected with the small gear, and a bottom end of the telescopic screw rod is fixedly connected to a universal joint.

[0016] By adopting the above technical solution, a special double-shaft motor with non-synchronous rotation of two output ends is adopted, which saves more space. Since the rotating frame and the rotating and telescoping frame need to rotate relative to each other, the rotating driving mechanism should be located at the center of the two. Therefore, on the premise that the size of the waterproof tape is fixed, a rotating and telescoping structure of a sleeve and a sleeve shaft directly driven by the output end of the rotating driving mechanism is not selected to save space; the rotating driving mechanism drives the small gear to rotate, so that the large gear rotates together, and the telescopic screw rod at the bottom of the large gear is threadedly connected to the rotating frame, so that the large gear can drive the rotating frame to lift when rotating, thus cooperating with the universal joint and the hinge of the clamping mechanism, so that the inclination angle of the clamping mechanism can be adjusted.

[0017] Optionally, it further includes a linear actuator, the linear actuator is installed on the upper and lower sides inside the machine frame and is symmetrically arranged around the through hole, a shearing frame is slidably connected to the machine frame, a soft roller is rotatably installed on the shearing frame, a shearing groove is provided on the shearing frame, a shearing block is slidably clamped in the shearing groove, a second soft roller is installed on the shearing block, the soft roller and the second soft roller are arranged in cooperation, a fourth spring is installed in the shearing groove, an output end of the fourth spring is connected to the shearing block, a first abutting block is installed inside the machine frame, a cutting knife is installed on the shearing block, and the first abutting block and the cutting knife are arranged in cooperation.

[0018] By adopting the above technical solution, after a group of lead screws are packed, the linear actuator extends to drive the shear frame to move forward to between the waterproof tape and the lead screw group. During the forward movement, the tape is located between the soft roller and the second soft roller. Then, under the push of the first abutting block, the second soft roller approaches the soft roller and cooperates with the soft roller to clamp the tape. Then the linear actuator continues to push, so that the soft roller and the second soft roller can undergo a certain deformation, and then the cutter cuts the tape. As a result, the tape can adhere to the soft roller. When the next group of lead screws needs to be wound and packed, the rotating frame continues to rotate. During the rotation, due to the pulling force of the tape on the rotating soft roller, the soft roller can rotate. Finally, the tape outlet end of the tape body, the adhesion between the tape and the lead screw, and the adhesion between the tape and the soft roller are on the same side. Thus, when the rotating frame continues to rotate, the tape can adhere to the lead screw. Therefore, when the linear actuator retracts, the tape no longer adheres to the soft roller but adheres to the next group of lead screws. Thus, the rotating frame can continue the packing work; during the process of continuing to move forward after the soft roller and the second soft roller abut, a part of the tape on the clamping mechanism will be pulled out. However, with the rotation of the rotating frame, this part of the stretched tape can be straightened again; after the cutter cuts the tape, there will always be a certain amount of un-wound tape remaining on the packed lead screws. When taking the material, it can be wound manually, and the tape between the lead screw and the cutter adhered to the lead screw is adhered into the lead screw during the vertical winding process; after the work is completed, the spring four in the shear groove can pull the shear block to reset it; since the lead screws can be fed from both sides of the frame, two groups of linear actuators are arranged symmetrically around the through hole. Finally, the automatic connection of the waterproof tape winding is realized, and there is no need to manually connect to the next group of lead screws after packing a group of lead screws.

[0019] Optionally, a second abutting block is installed on the cutter, the first abutting block and the second abutting block are arranged in cooperation, and chamfers are provided on both the first abutting block and the second abutting block.

[0020] By adopting the above technical solution, the abutment of the first abutting block and the second abutting block realizes that the second soft roller is driven to move and abut against the soft roller. The setting of the chamfers makes it difficult for the first abutting block and the second abutting block to be worn by a certain thickness, resulting in inaccurate cutting.

[0021] Optionally, a rotating groove is provided on the rotating frame, a fixing rod is installed on the rotating frame, and the fixing rod is slidably clamped in the rotating groove.

[0022] By adopting the above technical solution, since the fixing rod is slidably clamped in the rotating groove, when the rotating frame rotates relative to the rotating frame, it can be more stable.

[0023] Optionally, the clamping mechanism includes a hinged frame. One end of the hinged frame is hinged to the rotating frame. A guiding and limiting block is slidably clamped on the hinged frame. A rotating block is rotatably installed on the guiding and limiting block. A spring five is installed on the hinged frame. The output end of the spring five is connected to the guiding and limiting block. There is friction between the rotating block and the guiding and limiting block.

[0024] By adopting the above technical solution, when placing the waterproof tape, by squeezing the guiding and limiting block, the fifth spring is compressed and contracted, so that both ends of the tape can be clamped at the rotating block. Due to the extrusion of the fifth spring on the guiding and limiting block and the friction between the rotating block and the guiding and limiting block, when the tape drives the rotation, it can be released and will not continue to rotate and release a large distance of redundant tape after stopping; the tape should be wider at the central roller than at the tape, so that the central roller abuts against the rotating block, without affecting the release of the tape.

[0025] This technical solution has at least the following beneficial effects: 1. By providing a through groove on the frame and making the film sleeving ring with the plastic sealing soft film located therein, when the lead screw passes through, the plastic sealing soft film can be automatically sleeved under the pressure of the forward movement of the lead screw. When the lead screw after sleeving the film passes through the rotating frame, it can automatically wind the tape. Thus, the lead screw sleeving the film and winding the tape can be completed by the frame moving forward once. When reciprocating, the next group of lead screws can be packed, saving more labor. 2. The rotation drive mechanism controls the inclination angle of the clamping mechanism to control the inclination angle of the tape, thereby automatically controlling the winding inclination angle, avoiding the situations of winding errors, omissions and serious overlaps.

Detailed implementation manners

[0027] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Please refer to Figures 1 to 9 , this embodiment of the present application provides a screw packing device, including: The frame 1, on both sides of the frame 1, there are through holes 11 for the screw to pass through, and at the bottom of the frame 1, there is a moving mechanism 12; The through slot 21 is arranged on the frame 1, the through slot 21 penetrates the through hole 11, several film sleeve rings 22 are movably placed in the through slot 21, a plastic sealing soft film 23 is stacked on the film sleeve rings 22, and a limiting mechanism 24 is arranged on the inner wall of the through slot 21, and the output end of the limiting mechanism 24 abuts against the plastic sealing soft film 23; The rotating frame 31 is rotatably mounted on the frame 1 and can rotate concentrically around the through hole 11. A rotating frame 32 is rotatably mounted on the rotating frame 31. A rotating driving mechanism 33 is mounted on the rotating frame 32. The rotating driving mechanism 33 has two output ends, one of which is in transmission connection with the rotating frame 31. A rotating telescopic mechanism 34 is mounted on the rotating frame 32. The other output end of the rotating driving mechanism 33 is in transmission connection with the rotating telescopic mechanism 34, so that the rotating telescopic mechanism 34 is driven to telescope. A universal joint 35 is mounted on one end of the rotating telescopic mechanism 34 away from the rotating driving mechanism 33. A clamping mechanism 36 is hinged on the rotating frame 32. The universal joint 35 is rotatably connected to a side of the clamping mechanism 36 away from the hinged end. The fixing frame 41 is fixedly mounted on a wall or the ground. A support rod 42 is rotatably mounted on the fixing frame 41 . A spring is mounted on the fixing frame 41 , and an output end of the spring is connected to the support rod 42 .

[0029] The frame 1 can be moved under the drive of the moving mechanism 12, enabling the lead screw to be packed, which is placed on the support rod 42, to pass through the through hole 11 on the frame 1. When passing through, due to the abutment of the limiting mechanism 24 against the film sleeve ring 22 and the plastic sealing soft film 23 thereon, the plastic sealing soft film 23 can be gradually and evenly pulled out from the film sleeve ring 22 by the lead screw for film covering work, avoiding the rupture of the plastic sealing film 23 caused by a large pulling force; the limiting mechanism 24 can be driven by a spring to abut or be driven by an electric cylinder to extrude; a plastic thin pad can be added to the end of the plastic sealing soft film 23 abutted by the lead screw head, so as to further avoid the rupture of the end of the plastic sealing soft film 23; when the frame 1 passes by a support rod 42, it can abut against it and make it rotate back to near the fixed frame 41. After the frame 1 moves away, the spring can drive the support rod 42 to reset and support the lead screw again. The number of fixed frames 41 should be three or more, and the spring here is preferably a curved spring. The clamping mechanism 36 can be any fixture in the prior art, as long as it can clamp the waterproof tape and does not prevent the waterproof tape from rotating; after the waterproof tape drives the plastic sealing soft film 23 to move into the frame 1 at one end of the lead screw, one end of the waterproof tape installed at the clamping mechanism 36 can be wound around the lead screw. Then, the rotating frame 31 is driven to rotate. After the rotating frame 31 rotates several circles, that is, after vertically winding the head end of the lead screw, the rotation drive mechanism 33 starts to drive the rotating telescopic mechanism 34 to rotate, so that the rotating telescopic mechanism 34 can extend, enabling the clamping mechanism 36 to deflect along the hinge with the rotating frame 32, that is, to adjust the inclination angle. Thus, by driving the rotating telescopic mechanism 34 to rotate several circles and extend a specified distance by the rotation drive mechanism 33, the waterproof tape can be gradually inclined to a fixed angle for winding. When winding to the end of the lead screw, the clamping mechanism 36 is reset to continue vertical winding, so that film covering and winding can be carried out simultaneously, and the problems of rupture of the plastic sealing soft film 23, wrong or missing winding of the tape, and waste are avoided; when the plastic sealing film 23 is sleeved to the end of the lead screw, the plastic sealing film 23 on the film sleeve ring 22 gradually decreases, so that the pressure of the limiting mechanism 24 on it gradually decreases. Finally, when the film covering is completed, the lead screw can drive the film sleeve ring 22 to slide out of the through hole 11, and then the waterproof tape winds the film sleeve ring 22 and the lead screw together for packing.The rotation driving mechanism 33 can be two motors or a biaxial motor with asynchronous rotation of two output ends. The rotation and telescopic mechanism 34 can be a sleeve and a sleeve rod structure. The sleeve rod is threadedly connected to the rotating frame 32 to enable telescoping during rotation. Or it can be two relatively thick gears meshing with each other. When one gear rotates, it can drive the other gear and the screw rod threadedly connected to the rotating frame 32 to rotate and move downward. The relatively thick gears ensure that the two gears can always mesh. The output end of the rotation driving mechanism 33 is in transmission connection with the rotating frame 31. Thus, with the rotating frame 31 fixed, it can drive the rotating frame 32 to rotate 180° relative to the rotating frame 31, so as to perform bundling work on the lead screws passing through any through holes 11 on both sides of the frame 1. When the film sleeve ring 22 is taken out of the through slot 21, the upper film sleeve ring 22 can automatically fall off, facilitating the bundling of the next lead screw.

[0030] In one embodiment, please refer to Figure 2 , the moving mechanism 12 includes a driving shaft 121. The driving shaft 121 is rotatably installed on the frame 1. A second rotation driving device 122 is installed on the frame 1. The second rotation driving device 122 can be a servo motor. The output end of the second rotation driving device 122 is in transmission connection with the driving shaft 121. An adjusting gear 123 is rotatably installed on the frame 1. The adjusting gear 123 is in transmission connection with the driving shaft 121 through a transmission component. The transmission component can be a belt transmission component or a chain transmission component. A lifting frame 124 is slidably clamped in the through slot 21. A rack 125 is installed at the lower end of the lifting frame 124. The adjusting gear 123 is meshed with the rack 125. The lifting frame 124 and the limiting mechanism 24 cooperate to jointly limit and clamp the film sleeve ring 22. A second spring 126 is installed in the through slot 21. The output end of the second spring 126 is connected to the lifting frame 124. An opening for the lead screw to pass through is provided on the lifting frame 124.

[0031] By adopting the above technical solution, when the moving mechanism 12 drives the frame 1 to move in different directions, that is, the second rotary drive device 122 drives the driving shaft 121 to rotate in different directions, thereby driving the adjusting gear 123 to rotate through the transmission, and the meshing of the adjusting gear 123 and the rack 125 on the lifting frame 124 enables the lifting frame 124 at the front end of the moving direction of the frame 1 to be driven down, so that the sleeve membrane ring 22 above the lifting frame 124 can fall and be limited by the lifting frame 124 and the limiting mechanism 24, and the adjusting gear 123 at the rear end of the moving direction of the frame 1 can drive the lifting frame 124 to rise, so that when the screw rod passes here, it can be lifted from the lifting frame 1 24, and will not be reversely coated twice; there is a certain gap between the lifting frame 124 and the rack 125, so that when the lifting frame 124 is driven to the lowest point, the adjusting gear 123 will continuously collide with the top of the rack 125, and will not allow the lifting frame 124 to continue to descend under the support of the spring 126. Similarly, the rear end, the adjusting gear 123 will continuously collide with the bottom of the rack 125; the second spring 126 enables the lifting frame 124 that is slidably connected in the slide slot 21 to be reset; by increasing the number of teeth of the adjusting gear 123, when the lifting frame 124 is driven to reset by the second spring 126 during the working process, the shaking amplitude of the lifting frame 124 is reduced, thereby avoiding affecting the packaging work. Therefore, after the frame 1 completes the packaging of the screw rod, it does not need to be reset, and the staff can directly move back to pack after placing another set of screw rods.

[0032] In one embodiment, see Figure 2 The moving mechanism 12 further includes a plurality of traveling wheels 127, and the plurality of traveling wheels 127 are all connected to the driving shaft 121 through a transmission assembly, and the transmission assembly can be a belt transmission assembly or a chain transmission assembly.

[0033] By adopting the above technical solution, through the transmission connection of the transmission assembly, when the driving shaft 121 rotates, it can drive the plurality of traveling wheels 127 to rotate, so that the entire frame 1 can move forward or backward.

[0034] In one embodiment, see Figure 3 The limiting mechanism 24 includes a card slot 241, which is arranged on both sides of the inner wall of the through slot 21. A card block 242 is slidably connected in the card slot 241. A spring three 243 is installed in the card slot 241. The output end of the spring three 243 is connected to the card slot 241, and a chamfer is provided on the card block 242.

[0035] By adopting the above technical solution, when the lifting frame 124 moves upward, the clamping block 242 can be extruded, so that it compresses the third spring 243 and retracts into the clamping groove 241. When the rack 1 is driven to move reciprocally, since the film sleeving ring 22 is placed on the lifting frame 124, due to the chamfer setting of the clamping block 242, the film sleeving ring 22 can smoothly pass through the clamping block 242 without being limited above the through hole 11, thereby realizing the common limiting and clamping of the lifting frame 124 and the limiting mechanism 24 on the film sleeving ring 22.

[0036] In one embodiment, please refer to Figure 4 and Figure 5 , a ring groove 13 is provided on the rack 1, a clamping post 14 is installed on the rotating frame 31, the clamping post 14 is slidably clamped in the ring groove 13, a gear ring 15 is rotatably installed on the rack 1, the gear ring 15 is fixedly connected to the rotating frame 31, a third rotating driving device 16 is installed on the rack 1, the third rotating driving device 16 can be a servo motor, and an output end of the third rotating driving device 16 is installed with a rotating gear 17, and the rotating gear 17 is meshed and connected with the gear ring 15.

[0037] By adopting the above technical solution, through the sliding clamping of the clamping post 14 on the rotating frame 31 in the ring grooves 13 on both sides of the rack 1, the rotating frame 31 is driven to rotate stably on the rack 1; the third rotating driving device 16 drives the rotating gear 17 to rotate, and through the meshing of the rotating gear 17 and the gear ring 15, the gear ring 15 can drive the rotating frame 31 to make a circumferential rotation around the through hole 11.

[0038] In one embodiment, the rotating driving mechanism 33 is preferably a dual-axis motor; the rotating and telescoping mechanism 34 includes a small gear 341, an output end of the dual-axis motor is in transmission connection with the small gear 341, a telescopic screw 342 is threadedly connected to the rotating frame 32, a large gear 343 is installed on the telescopic screw 342, the large gear 343 is meshed and connected with the small gear 341, and a bottom end of the telescopic screw 342 is fixedly connected to a universal joint 35.

[0039] By adopting the above technical solution, a special dual-axis motor with non-synchronous rotation of two output ends is adopted, which saves more space. Since the rotating frame 31 and the rotating frame 32 need to rotate relatively, the rotating driving mechanism 33 should be located at the center of the two. Therefore, on the premise that the size of the waterproof tape is fixed, a rotating and telescopic structure of a sleeve and a sleeve shaft directly driven by the output end of the rotating driving mechanism 33 is not selected to save space; the rotating driving mechanism 33 drives the small gear 341 to rotate, so that the large gear 343 rotates together. The threaded connection between the telescopic screw 342 at the bottom of the large gear 343 and the rotating frame 342 enables the large gear 343 to drive it to lift when rotating, so as to cooperate with the hinge of the universal joint 35 and the clamping mechanism 36, so that the inclination angle of the clamping mechanism 36 can be adjusted.

[0040] In one embodiment, refer to Figure 6 , it further includes a linear actuator 51. The linear actuator 51 can be an electric cylinder. The linear actuator 51 is installed on the upper and lower sides inside the frame 1 and is symmetrically arranged around the through hole 11. A shearing frame 52 is slidably connected to the frame 1. A soft roller 53 is rotatably installed on the shearing frame 52. A shearing groove 54 is provided on the shearing frame 52. A shearing block 55 is slidably clamped in the shearing groove 54. A second soft roller 56 is installed on the shearing block 55. The soft roller 53 and the second soft roller 56 are arranged in cooperation. A fourth spring 57 is installed in the shearing groove 54. The output end of the fourth spring 57 is connected to the shearing block 55. An abutting block 58 is installed inside the frame 1. A cutting knife 59 is installed on the shearing block 55. The abutting block 58 and the cutting knife 59 are arranged in cooperation.

[0041] By adopting the above technical solution, after a group of lead screws are packed, the linear actuator 51 extends to drive the shearing frame 54 to move forward to between the waterproof tape and the lead screw group. During the forward movement, the tape is located between the soft roller 53 and the second soft roller 56. Then, under the push of the abutting block 58, the second soft roller 56 approaches the soft roller 53 and cooperates with the soft roller 53 to clamp the tape. Then the linear actuator 51 continues to push, so that after the soft roller 53 and the second soft roller 56 can undergo a certain deformation, the cutting knife 59 cuts off the tape, so that the tape can adhere to the soft roller 53. When the next group of lead screws needs to be wound and packed, the rotating frame 31 rotates again. During the rotation, due to the pulling force of the tape on the rotating soft roller 53, the soft roller 53 can rotate. Finally, the tape outlet end of the tape body, the tape and the lead screw, and the adhesion part of the tape and the soft roller 53 are on the same side. Thus, after the rotating frame 31 continues to rotate, the tape can adhere to the lead screw. Thus, when the linear actuator 51 retracts, the tape no longer adheres to the soft roller 53 but adheres to the next group of lead screws. Thus, the rotating frame 31 can continue the packing work; during the process of the soft roller 53 and the second soft roller 56 abutting and then continuing to move forward, a part of the tape on the clamping mechanism 36 will be pulled out, but as the rotating frame 31 rotates, this part of the stretched tape can be straightened again; after the cutting knife 59 cuts off the tape, there will usually be a certain amount of uncoiled tape left on the packed lead screws. When taking the material, it can be wound manually, and the tape between the lead screw adhered to the lead screw and the cutting knife 59 will be adhered into the lead screw during the vertical winding process; after the work is completed, the fourth spring 57 in the shearing groove 54 can pull the shearing block 55 to reset it; since the lead screws can be fed from both sides of the frame 1, two groups of linear actuators 51 are arranged symmetrically around the through hole 11. Finally, the automatic connection of the waterproof tape winding is realized, and there is no need to manually connect to the next group of lead screws after packing a group of lead screws.

[0042] In one embodiment, refer to Figure 6 , a second abutting block 591 is installed on the cutting knife 59. The abutting block 58 and the second abutting block 591 are arranged in cooperation. Chamfers are provided on both the abutting block 58 and the second abutting block 591.

[0043] By adopting the above technical solution, the abutting of the first abutting block 58 and the second abutting block 591 enables the second soft roller 56 to be driven to move and abut against the soft roller 53. The chamfer setting makes it difficult for the first abutting block 58 and the second abutting block 591 to be worn by a certain thickness, resulting in inaccurate cutting.

[0044] In one embodiment, a rotating groove 311 is provided on the rotating frame 31, and a fixing rod 312 is installed on the rotating frame 32. The fixing rod 312 is slidably clamped in the rotating groove 311.

[0045] By adopting the above technical solution, since the fixing rod 312 is slidably clamped in the rotating groove 311, when the rotating frame 32 rotates relative to the rotating frame 31, it can be more stable.

[0046] In one embodiment, the clamping mechanism 36 includes a hinged frame 363. One end of the hinged frame 363 is hinged to the rotating frame 32. A guiding and limiting block 362 is slidably clamped on the hinged frame 363. A rotating block 361 is rotatably installed on the guiding and limiting block 362. A fifth spring is installed on the hinged frame 363, and the output end of the fifth spring is connected to the guiding and limiting block 362. There is friction between the rotating block 361 and the guiding and limiting block 362.

[0047] By adopting the above technical solution, when placing the waterproof tape, by squeezing the guiding and limiting block 362, it compresses the fifth spring and contracts, so that both ends of the tape can be clamped at the rotating block 361. Through the squeezing of the fifth spring on the guiding and limiting block 362 and the friction between the rotating block 361 and the guiding and limiting block 362, the tape can be released when it is driven to rotate and will not continue to rotate and release a large distance of excess tape after stopping; the tape should be wider at the central roller than at the tape, so that it abuts against the rotating block 361 at the central roller without affecting the release of the tape.
