Description

Technical Field

[0001] This invention relates to the field of sock processing equipment technology, specifically to a curling device for sock packaging and its usage method. Background Technology

[0002] As is well known, the sock packaging curling device is a specialized actuator on automated sock packaging lines responsible for neatly rolling folded socks into a cylindrical shape, thereby reducing manual labor consumption during sock packaging. Existing double-clamp sock curling devices have the following main problems: 1. The two clamping rods used to clamp and rotate the socks require manual operation, and the clamping force gradually decreases with long-term use of the springs, hindering long-term efficient and stable use of the clamping rods on the sock curling device; 2. After long-term use, wear and tear on the clamping rods can cause hard bumps on their surface, easily damaging the sock surface during clamping. Directly replacing the clamping rods not only leads to high maintenance costs but also requires disassembling and reassembling multiple bolts, thus the ease of maintenance for the sock curling device still needs improvement. Therefore, this paper proposes a sock packaging curling device and its usage method. Summary of the Invention

[0003] The purpose of this invention is to provide a rolling device for packaging socks and a method for using the same, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a curling device for packaging socks, comprising: a box, a drive unit, an automatic clamping unit, and a wear-resistant unit; The drive unit includes a stand fixedly installed inside the housing, a servo motor fixedly installed on the stand, a main shaft fixedly connected to the output shaft of the servo motor, a bracket fixedly connected to one end of the main shaft, a plate fixedly connected to one side of the bracket, and two clamping rods provided on one side of the plate. The automatic clamping unit includes a forward and reverse motor. The housing of the forward and reverse motor is fixedly connected to the bracket via a connecting seat. The output shaft of the forward and reverse motor is fixedly connected to a driving bevel gear. A driven bevel gear is meshed with the outer side of the driving bevel gear. A bidirectional lead screw is fixedly embedded inside the driven bevel gear. A slider is threaded onto each of the two opposite threads of the bidirectional lead screw. One side of the slider penetrates the plate and is fixedly connected to the clamping rod. The wear-resistant unit includes a wear-resistant ceramic tube that is detachably mounted on the clamping rod.

[0005] Preferably, the wear-resistant unit further includes a protrusion fixedly connected to one end of the clamping rod. The protrusion has a slot inside, and a compression spring is symmetrically fixedly connected to the inner wall of the slot through a baffle. One end of the compression spring is fixedly connected to the clamping block.

[0006] Preferably, the inner wall of the empty groove is provided with a sliding groove, and a block is slidably connected to the inner side wall of the sliding groove. One side of the block is fixedly connected to a clamping block.

[0007] Preferably, the outer side of the wear-resistant ceramic tube is fixedly provided with equidistantly distributed anti-slip ridges.

[0008] Preferably, a controller for controlling the operating status of the servo motor and the forward and reverse motor is fixedly installed at the bottom of the housing.

[0009] Preferably, a door is hinged to the side of the box near the opening, a protective cover is fixedly connected to one side of the plate, and a cover plate is fixedly connected to one side of the protective cover by screws.

[0010] Preferably, a conductive slip ring is fixedly embedded inside the support frame, the main shaft passes through the inside of the conductive slip ring rotor without making contact, and a wire conduit is fixedly connected to the conductive wire outlet of the forward and reverse motor, one end of the wire conduit being fixedly connected to the rotor of the conductive slip ring.

[0011] Preferably, the plate body has a through groove inside, and a rod is fixedly embedded in the inner side wall of the through groove. The slider is slidably connected to the rod inside the through groove.

[0012] In addition, the present invention also provides a method of using a curling device for packaging socks, comprising: Step 1: Insert one end of a folded sock into the gap between the two wear-resistant ceramic tubes. Control the forward and reverse motor to drive the active bevel gear to rotate clockwise. After the lead screw rotates under the action of the driven bevel gear, it drives the two sliders to move closer to each other, so that the two wear-resistant ceramic tubes clamp the end of the sock under the action of the clamping rod. Step 2: Start the servo motor. The servo motor drives the bracket to rotate through the spindle, so that the plate body drives the two clamping rods to rotate synchronously through the slider under the action of the bracket, so that the sock can be curled. Step 3: After the curling is completed, the servo motor stops running. At this time, the control motor drives the active bevel gear to rotate counterclockwise. After the lead screw rotates under the action of the driven bevel gear, it drives the two sliders to move away from each other, so that the two wear-resistant ceramic tubes are released under the action of the clamping rod, and the curled socks can be removed. Step 4: After the wear-resistant ceramic tube is worn, press the two clamping blocks into the empty groove at the same time to remove the clamping force on the wear-resistant ceramic tube, and then remove the worn wear-resistant ceramic tube from the clamping rod. Step 5: When the replaced wear-resistant ceramic tube is installed on the clamping rod, the two clamping blocks are squeezed into the empty slot by the inner cavity of the wear-resistant ceramic tube and squeeze the compression spring. When one end of the wear-resistant ceramic tube is pressed against the plate, the two clamping blocks move out of the empty slot again under the tension of the compression spring and clamp the end of the wear-resistant ceramic tube away from the plate, thus completing the replacement of the wear-resistant ceramic tube.

[0013] Preferably, in step five, in order to increase the clamping force of the clamping block on the wear-resistant ceramic tube, a rubber pad is fixedly connected to the side of the clamping block near the clamping rod.

[0014] In summary, this application includes at least one of the following beneficial technical effects: This invention, by separately assembling a drive unit, an automatic clamping unit, and a wear-resistant unit within the housing, enables the forward and reverse motors to move two clamping rods closer together or further apart after startup, thereby automatically clamping or releasing the socks. Furthermore, the servo motor of the drive unit, once activated, can curl the clamped socks. The wear-resistant ceramic tubes mounted on the clamping rods are also easy to disassemble and replace. These features not only further reduce the manual labor required for clamping, facilitating long-term, efficient, and stable use of the clamping rods in the sock curling device, but also solve the problems of clamping rod wear and high replacement costs in sock curling devices.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-7 The present invention provides a technical solution: a curling device for packaging socks, comprising: a box 1, a driving unit 2, an automatic clamping unit 3, and a wear-resistant unit 4; First, in order for the servo motor 21 to drive the bracket 23 to rotate through the spindle 22 after starting, so that the two clamping rods 25 can quickly rotate under the action of the plate 24 after clamping the sock, thereby realizing the curling of the sock, the drive unit 2 includes a stand 20 fixedly installed inside the housing 1. The servo motor 21 is fixedly installed on the stand 20. The output shaft of the servo motor 21 is fixedly connected to the spindle 22. One end of the spindle 22 is fixedly connected to the bracket 23. One side of the bracket 23 is fixedly connected to the plate 24. Two clamping rods 25 are provided on one side of the plate 24. Secondly, so that when the sock's cup is placed between the two clamping rods 25, the reversible motor 31 can drive the bidirectional lead screw 34 to rotate clockwise or counterclockwise via the driving bevel gear 32 and the driven bevel gear 33, thereby allowing the two sliders 35 to move closer or further apart under the action of the bidirectional lead screw 34. This enables the two clamping rods 25 to automatically clamp or release the sock under manual control. The automatic clamping unit 3 includes a reversible motor 31. The housing of the reversible motor 31 is fixedly connected to the bracket 23 via a connecting seat 30. The output shaft of the reversible motor 31 is fixedly connected to the driving bevel gear 32. The outer side of the driving bevel gear 32 is meshed with the driven bevel gear 33. The bidirectional lead screw 34 is fixedly embedded inside the driven bevel gear 33, and the bidirectional lead screw 34 has two opposite threads. The upper part is threaded with a slider 35, one side of which penetrates the plate 24 and is fixedly connected to the clamping rod 25. In order to prevent the wire from getting tangled when the forward and reverse motor 31 rotates under the action of the servo motor 21 via the bracket 23, a conductive slip ring 37 is fixedly embedded inside the upright 20. The main shaft 22 passes through the inside of the rotor of the conductive slip ring 37 without making contact. A wire tube 36 is fixedly connected to the conductive wire outlet of the forward and reverse motor 31. One end of the wire tube 36 is fixedly connected to the rotor of the conductive slip ring 37. In order to keep the two sliders 35 moving smoothly in a straight line under the action of the bidirectional lead screw 34, a through groove 38 is opened inside the plate 24. A rod 39 is fixedly embedded in the inner side wall of the through groove 38. The inside of the slider 35 is slidably connected to the rod 39, and the slider 35 passes through the inside of the through groove 38. Furthermore, to prevent the clamping rod 25 from being directly worn after long-term use, the wear-resistant unit 4 includes a wear-resistant ceramic tube 40 that is detachably fitted onto the clamping rod 25. When the clamping rod 25 penetrates the interior of the wear-resistant ceramic tube 40 and one end of the wear-resistant ceramic tube 40 is pressed against the surface of the plate 24, the clamping block 43 can move into the slot 44 under the squeezing action of the inner cavity of the wear-resistant ceramic tube 40. When one end of the protrusion 42 extends out of the wear-resistant ceramic tube 40, the clamping block 43, no longer in contact with the inner cavity of the wear-resistant ceramic tube 40, can automatically extend out of the slot 44 under the action of the compression spring 46, thereby fixing the end of the wear-resistant ceramic tube 40 away from the plate 24 by the clamping block 43. The element 4 also includes a protrusion 42 fixedly connected to one end of the clamping rod 25. The protrusion 42 has a slot 44 inside. The inner wall of the slot 44 is symmetrically fixedly connected to a compression spring 46 through a baffle 45. One end of the compression spring 46 is fixedly connected to the clamping block 43. In order to ensure that the clamping block 43 maintains a stable linear movement under the action of the compression spring 46, a sliding groove 47 is provided on the inner wall of the slot 44. A block 48 is slidably connected to the inner side wall of the sliding groove 47. One side of the block 48 is fixedly connected to the clamping block 43. In order to improve the stability of the wear-resistant ceramic tube 40 when clamping socks, the outer side of the wear-resistant ceramic tube 40 is fixedly provided with equidistantly distributed anti-slip ridges 41. Furthermore, in order to facilitate manual control of the drive unit 2 and the automatic clamping unit 3, a controller 11 for controlling the operating status of the servo motor 21 and the forward and reverse motor 31 is fixedly installed at the bottom of the housing 1; in order to facilitate effective protection of the components inside the housing 1 when the device is not working, and also to enable opening and maintenance when necessary, a door 10 is hinged to the side of the housing 1 near the opening, a protective cover 301 is fixedly connected to one side of the plate 24, and a cover plate 302 is fixedly connected to one side of the protective cover 301 by screws.

[0019] In addition, the present invention also provides a method of using a curling device for packaging socks, comprising: Step 1: Insert one end of a folded pair of socks into the adjacent gap between the two wear-resistant ceramic tubes 40. Control the forward and reverse motor 31 to drive the active bevel gear 32 to rotate clockwise. After the lead screw rotates under the action of the driven bevel gear 33, it drives the two sliders 35 to move closer to each other, so that the two wear-resistant ceramic tubes 40 clamp the end of the sock under the action of the clamping rod 25. Step 2: Start the servo motor 21. The servo motor 21 drives the bracket 23 to rotate through the spindle 22, so that the plate 24 drives the two clamping rods 25 to rotate synchronously through the slider 35 under the action of the bracket 23, so that the sock can be curled. Step 3: After the curling is completed, the servo motor 21 stops running. At this time, the control motor 31 drives the active bevel gear 32 to rotate counterclockwise. After the lead screw rotates under the action of the driven bevel gear 33, it drives the two sliders 35 to move away from each other, so that the two wear-resistant ceramic tubes 40 are released under the action of the clamping rod 25, and the curled socks can be removed. Step 4: After the wear-resistant ceramic tube 40 is worn, press the two clamping blocks 43 into the empty groove 44 at the same time, so that the clamping blocks 43 remove the clamping force on the wear-resistant ceramic tube 40, and then remove the worn wear-resistant ceramic tube 40 from the clamping rod 25. Step 5: When the replaced wear-resistant ceramic tube 40 is fitted onto the clamping rod 25, the two clamping blocks 43 are squeezed into the empty groove 44 by the inner cavity of the wear-resistant ceramic tube 40 and squeeze the compression spring 46. When one end of the wear-resistant ceramic tube 40 is pressed against the plate 24, the two clamping blocks 43 are moved out of the empty groove 44 again under the tension of the compression spring 46 and clamp the end of the wear-resistant ceramic tube 40 away from the plate 24, thus completing the replacement of the wear-resistant ceramic tube 40.

[0020] It should be noted that in step five, in order to increase the clamping force of the clamping block 43 on the wear-resistant ceramic tube 40, a rubber pad is fixedly connected to the side of the clamping block 43 near the clamping rod 25.

[0021] All parts not described in this invention are the same as or can be implemented using existing technology. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
