Description

Technical Field

[0001] This utility model relates to the field of enameled wire production technology, and in particular to an attachment mechanism for enameled wire production. Background Technology

[0002] Enameled wire, as the core type of winding wire, consists of a conductor and an insulation layer. It is manufactured through bare wire annealing and softening, multiple coatings, and baking. After production, it is usually wound on a spool for transportation and shipment. To protect the insulation layer of the outermost ring of enameled wire from damage, a protective sticker needs to be affixed to the surface of this outer ring of enameled wire.

[0003] In existing technologies, sticker application is mostly done manually, which has several drawbacks: First, the wire reel is quite heavy, and manually rotating the reel to apply the sticker results in extremely high labor intensity for workers. Second, manually applying the sticker around the reel can easily cause the sticker to wrinkle or even damage the insulation layer of the enameled wire. Furthermore, manual operation is difficult to adapt to automated production processes, severely limiting production efficiency.

[0004] Meanwhile, in the field of automated equipment for enameled wire production, although some conveying devices can transport wire reels, there is a lack of mechanisms that can make the wire reels rotate synchronously around their own axis during the transport process, which cannot meet the requirements of automated sticker application for the "transportation + rotation" composite motion; and existing paper feeding devices are also difficult to accurately and stably transfer the stickers to the side of the wire reel and achieve flat application, which further restricts the automation process of enameled wire production.

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figures 1 to 5 In this embodiment of the utility model, an attachment mechanism for enameled wire production is characterized by comprising a conveying device 10, a rotating device 30, and a paper feeding device 40. The conveying device 10 includes a conveying bracket 12, a conveying roller group 20, and a conveying motor 11. The conveying motor 11 is fixed to the conveying bracket 12, and the conveying roller group 20 is rotatably connected to the conveying bracket 12. The conveying motor 11 is also connected to the conveying roller group 20 in a transmission manner to drive the conveying roller group 20 to rotate and convey the coil 70 on it in the forward direction. The rotating device 30 includes a forward rotating roller group 31 and a reverse rotating roller group 34 rotatably connected to the conveying bracket 12. The rotation direction of the forward rotating roller group 31 is the same as that of the conveying roller group 20, and the rotation direction of the reverse rotating roller group 34 is opposite to that of the conveying roller group 20. The forward rotating roller group 31 and the reverse rotating roller group 34 cooperate to drive the coil 70 to rotate around its own axis while conveying in the forward direction. The paper feeding device 40 includes a paper feeding bracket 41, a paper feeding robot 42, and a paper feeding suction cup 65. The paper feeding robot 42 is mounted on the paper feeding bracket 41, and the paper feeding suction cup 65 is mounted on the drive end of the paper feeding robot 42. The paper feeding suction cup 65 is used to pick up the sticker 72. The paper feeding robot 42 is used to drive the paper feeding suction cup 65 to move the sticker 72 to the side of the forward conveying coil 70, and to attach the sticker 72 to the enameled wire 71 on the side of the coil 70. The sticker 72 is synchronously wound around the enameled wire 71 along with the rotating coil 70 to complete the attachment.

[0026] Specifically, enameled wire 71 is the main type of winding wire, consisting of a conductor and an insulation layer. The bare wire is manufactured through annealing and softening, multiple coatings, and baking. After the enameled wire 71 is produced, it is usually wound on a spool 70 for transportation and shipment. To protect the insulation layer of the outermost ring of enameled wire 71 on the spool 70 from damage, a protective sticker 72 needs to be attached to the outermost ring of enameled wire 71.

[0027] Existing wire bonding operations are mostly performed manually, which has significant drawbacks: the wire reel 70 is quite heavy, and if bonding is achieved by rotating the reel 70, the labor intensity for workers is extremely high; if the sticker 72 is applied by wrapping it around the reel 70, it is easy for the sticker 72 to wrinkle or even damage the enameled wire 71. In addition, manual operation is difficult to adapt to automated production processes, which seriously restricts production efficiency.

[0028] This invention adds a rotating device 30 to the conveying device 10, allowing the wire reel 70 to simultaneously achieve forward conveying and self-rotation without detaching from the conveying device 10. This eliminates the need for frequent handling of the wire reel 70 for loading and unloading, reducing labor intensity and improving production efficiency. Simultaneously, the paper feeding device 40 automates the transfer and application of the sticker 72: the paper feeding robot 42 drives the paper feeding suction cup 65 to pick up the sticker 72, then moves it to the side of the wire reel 70 and attaches the first end of the sticker 72 to the outer ring of enameled wire 71. Subsequently, the sticker 72 continues to wind around as the wire reel 70 rotates, ultimately bonding the tail end of the sticker 72 with the head end, forming a complete protective structure and ensuring flat and reliable application.

[0029] In addition, since the paper feeding bracket 41 needs to support the entire paper feeding device 40, it is preferred to install it directly on a solid platform such as the ground and install it on the side along the production direction of the conveying device 10, so that the paper feeding device 40 can smoothly push the sticker 72 to the reel 70 for application.

[0030] like Figures 1 to 3As shown, preferably, the conveying bracket 12 is fixedly connected to roller fixing plates 13 on both sides along the production direction; the conveying roller group 20 includes multiple long conveying rollers 21, the two ends of the long conveying rollers 21 are rotatably connected to the roller fixing plates 13 on both sides, and the end of the long conveying roller 21 near the conveying motor 11 is provided with a conveying sprocket 22. The multiple long conveying rollers 21 rotate synchronously through the cooperation of the chain and the conveying sprocket 22; the conveying motor 11 is fixedly connected to the roller fixing plate 13 and is drivenly connected to one of the long conveying rollers 21.

[0031] Specifically, to achieve stable conveying of the wire reel 70, roller fixing plates 13 are respectively set on both sides of the conveying bracket 12. Multiple long conveying rollers 21 are rotatably connected between the two roller fixing plates 13 through bearings to ensure smooth rotation of the long conveying rollers 21. Since there are a large number of long conveying rollers 21 and they need to rotate synchronously, a chain-sprocket drive method is adopted: all long conveying rollers 21 are equipped with a conveying sprocket 22 at the end near the conveying motor 11, and the conveying sprockets 22 are connected by a roller chain. The conveying motor 11 is installed on the roller fixing plate 13 and is connected to any one of the long conveying rollers 21. After starting, it drives all long conveying rollers 21 to rotate synchronously through the chain, realizing the forward conveying of the wire reel 70.

[0032] The roller chain is a conventional mechanical power transmission chain, composed of a series of short cylindrical rollers connected together and driven by a sprocket. It features a simple structure, high reliability, and high transmission efficiency, and is widely used in various types of machinery such as conveyors, printing presses, and automobiles. The conveyor motor 11 is preferably a right-angle geared motor, whose installation method is adapted to the structural layout of the roller fixing plate 13, and allows for flexible adjustment of the conveying speed of the conveying device 10 to meet the needs of different production conditions.

[0033] like Figures 1 to 3 As shown, preferably, the conveying bracket 12 has a forward rotation fixing seat 14 and a reverse rotation fixing seat 15 in the middle area between the two roller fixing plates 13; one end of the forward rotation roller group 31 is rotatably connected to the roller fixing plate 13 near the conveying sprocket 22, and the other end is rotatably connected to the forward rotation fixing seat 14; one end of the reverse rotation roller group 34 is rotatably connected to the roller fixing plate 13 away from the conveying sprocket 22, and the other end is rotatably connected to the reverse rotation fixing seat 15; a strip-shaped interval area 16 is formed between the forward rotation fixing seat 14 and the reverse rotation fixing seat 15 along the production direction; the lower end of the coil 70 overlaps the forward rotation roller group 31 and the reverse rotation roller group 34 respectively, and while the coil 70 is conveyed in the forward direction along the axis of the strip-shaped interval area 16, it rotates around its own axis under the cooperative drive of the forward rotation roller group 31 and the reverse rotation roller group 34.

[0034] Specifically, the height of both the forward-rotating fixed seat 14 and the reverse-rotating fixed seat 15 is lower than that of the corresponding forward-rotating roller group 31 and reverse-rotating roller group 34, ensuring that the lower end of the coil 70 can directly contact the forward-rotating roller group 31 and reverse-rotating roller group 34. Thus, through their opposing rotations, forward conveying and self-rotation are simultaneously achieved. The sum of the lengths of the forward-rotating roller group 31 and the reverse-rotating roller group 34 is less than the length of the conveying roller group 20, creating a non-interfering strip-shaped interval area 16 between them, preventing interference between the coil 70 and the fixed seat during movement.

[0035] Corresponding to the strip-shaped interval area 16, the conveying bracket 12 is provided with a support crossbar. The forward rotation fixing seat 14 and the reverse rotation fixing seat 15 are respectively fixed to the support crossbar. The support crossbar provides stable support to ensure the installation accuracy and rotational stability of the forward rotation roller group 31 and the reverse rotation roller group 34.

[0036] In addition, a guide plate (not shown in the figure) can be added to the receiving end of the conveyor 10 to guide the coil 70 from the previous station smoothly into the middle area between the two roller fixing plates 13, ensuring that the coil 70 accurately overlaps the forward-rotating roller group 31 and the reverse-rotating roller group 34. A photoelectric sensor (not shown in the figure) can be installed on the guide plate to sense the entering coil 70 and send a signal back to the equipment control system. The control system automatically controls the timing of the paper feeding device 40 based on the signal to ensure that the sticker 72 is accurately transferred to the side of the coil 70 for attachment. The guide plate, photoelectric sensor and control system all adopt existing technology or existing products, and their specific structures and connection methods will not be described in detail here.

[0037] like Figures 1 to 3 As shown, preferably, the forward rotating roller group 31 includes multiple forward rotating short rollers 32. One end of the forward rotating short roller 32 is rotatably connected to the forward rotating fixed seat 14, and the other end is rotatably connected to the corresponding roller fixed plate 13. A forward rotating sprocket 33 is provided at the end of the forward rotating short roller 32 away from the forward rotating fixed seat 14. The forward rotating sprocket 33 is connected to the conveying sprocket 22 through chain drive.

[0038] Specifically, since the forward-rotating roller group 31 needs to maintain the same rotation direction and speed as the conveyor roller group 20, a forward-rotating sprocket 33 is mounted at the end of the forward-rotating short roller 32 away from the forward-rotating fixed seat 14, and this forward-rotating sprocket 33 is connected to the transmission chain used by the conveyor sprocket 22, so that the chain simultaneously drives the conveyor long roller 21 and the forward-rotating short roller 32 to rotate synchronously. This design eliminates the need for an additional drive motor, simplifies the equipment structure, reduces production costs, and ensures the motion coordination between the forward-rotating roller group 31 and the conveyor roller group 20.

[0039] like Figure 2 and Figure 3As shown, preferably, the reverse roller assembly 34 includes multiple reverse short rollers 35. One end of each reverse short roller 35 is rotatably connected to the reverse fixing seat 15, and the other end is rotatably connected to the corresponding roller fixing plate 13. A reverse sprocket 36 is provided at the end of each reverse short roller 35 away from the reverse fixing seat 15. The reverse roller assembly 34 also includes a reverse power assembly, which is connected to the reverse sprocket 36 for driving the reverse sprocket 36 and the reverse short rollers 35 to rotate in the opposite direction.

[0040] Specifically, since the rotation direction of the reversing roller group 34 needs to be opposite to that of the conveying roller group 20, it cannot be directly connected to the transmission chain of the conveying roller group 20. Therefore, an independent reversing power component is required to provide reverse driving force for the reversing roller group 34. The reversing power component can be implemented in two ways: one is to set up an independent motor to directly drive the reversing roller group 34 to rotate in the reverse direction; the other is to set up a power conversion device to convert the forward rotation power of the conveying roller group 20 into reverse power and then transmit it to the reversing roller group 34.

[0041] Multiple reversing short rollers 35 are connected by a reversing chain drive. The reversing power component only needs to drive one of the reversing short rollers 35 to rotate in the opposite direction to drive all the reversing short rollers 35 to rotate synchronously in the opposite direction through the reversing chain, ensuring the consistency of movement of the reversing roller group 34. The forward rotating short rollers 32 and the reversing short rollers 35 are rotatably connected to the roller fixing plate 13, the forward rotating fixing seat 14 or the reversing fixing seat 15 respectively through bearings, reducing rotational friction and extending the service life of the equipment.

[0042] like Figure 2 and Figure 3 As shown, preferably, the reversing power assembly includes a first gear 37 and a second gear 38; the first gear 37 is fixed to one end of a long conveying roller 21 near the reversing roller group 34 away from the conveying sprocket 22, and rotates synchronously in the forward direction with the long conveying roller 21; the second gear 38 is fixed to one end of a short reversing roller 35 near the first gear 37 where the reversing sprocket 36 is located, and the second gear 38 meshes with the first gear 37 to convert the forward rotation of the first gear 37 into reverse rotation and transmit it to the short reversing roller 35.

[0043] Specifically, to further simplify the equipment structure and reduce costs, this solution uses gear meshing to achieve power direction conversion, eliminating the need for an independent motor or complex power conversion device. The first gear 37 is fixedly installed at the end of the long conveying roller 21 near the reverse roller group 34 away from the conveying sprocket 22, and rotates synchronously in the forward direction with the long conveying roller 21; the second gear 38 is fixedly installed at the end of the corresponding reverse short roller 35 where the reverse sprocket 36 is located, and meshes with the first gear 37.

[0044] When the first gear 37 rotates in the forward direction, it drives the second gear 38 to rotate in the reverse direction through meshing. The second gear 38 drives the reverse short roller 35 fixed to it to rotate in the reverse direction synchronously. Then, the reverse rotation is transmitted to all the reverse short rollers 35 through the reverse chain, so as to realize the reverse roller group 34 and the conveying roller group 20 to rotate in the opposite direction synchronously, providing a stable driving force for the rotation of the coil 70.

[0045] like Figure 1 , Figure 4 and Figure 5 As shown, preferably, the paper feeding robot 42 includes a vertical movement mechanism 50, a rotation mechanism 43, and a pushing mechanism 60; the vertical movement mechanism 50 is mounted on the paper feeding bracket 41, the rotation mechanism 43 is mounted on the drive end of the vertical movement mechanism 50, and moves vertically with the vertical movement mechanism 50; the pushing mechanism 60 is mounted on the rotation end of the rotation mechanism 43, and rotates with the rotation mechanism 43; the paper feeding suction cup 65 is mounted on the drive end of the pushing mechanism 60, and is used to pick up the sticker 72 and complete the attachment under the drive of the pushing mechanism 60.

[0046] Specifically, to simplify the equipment structure, this solution sets the initial placement position of the sticker 72 and the attachment position of the wire reel 70 to be flush along the production direction, eliminating the need for an additional lateral drive mechanism along the production direction. The vertical movement mechanism 50 enables the vertical movement of the paper feeding suction cup 65, adapting to the difference between the placement height of the sticker 72 on the ground and the attachment height of the wire reel 70. The rotation mechanism 43 achieves the posture conversion of the sticker 72, rotating the flat sticker 72 90° to a vertical position to match the vertical conveying posture of the wire reel 70. The pushing mechanism 60 pushes the sticker 72 towards the wire reel 70 in the middle of the conveying device 10, ensuring that the sticker 72 is accurately attached to the outer ring of the enameled wire 71 of the wire reel 70.

[0047] like Figure 4 and Figure 5 As shown, preferably, the vertical movement mechanism 50 includes a vertical movement support 51, a vertical movement slide rod 52, a vertical movement guide rail 53, a vertical movement rack 54, a vertical movement gear 55, and a vertical movement motor 56; the vertical movement support 51 is fixedly connected to the paper feeding bracket 41, the vertical movement guide rail 53 and the vertical movement rack 54 are respectively fixedly connected to the vertical movement slide rod 52, and the vertical movement slide rod 52 is slidably connected to the vertical movement support 51 through a linear slider and the cooperation of the vertical movement guide rail 53; the vertical movement motor 56 is fixedly connected to the vertical movement support 51, and the vertical movement motor 56 is configured as a servo motor, which is connected to the vertical movement gear 55 through a reduction mechanism, and the vertical movement gear 55 meshes with the vertical movement rack 54 to drive the vertical movement slide rod 52 to move vertically; an anti-detachment block is fixedly connected to the top end of the vertical movement slide rod 52, and the rotation mechanism 43 and the pushing mechanism 60 are assembled at the bottom end of the vertical movement slide rod 52.

[0048] Specifically, the vertical movement mechanism 50 needs to drive the rotating mechanism 43, the pushing mechanism 60, and the paper feeding suction cup 65 to complete vertical lifting and lowering. It must have sufficient load-bearing capacity and motion stability. Therefore, a combination structure of vertical movement support 51 and vertical movement slide bar 52 is adopted. Through the cooperation of the linear slider and the vertical movement guide rail 53, the vertical movement of the slide bar 52 is ensured to be smooth and without deviation. The vertical movement motor 56 is a servo motor. With the help of a reduction mechanism, the lifting height of the vertical movement slide bar 52 can be precisely adjusted, ensuring that the adhesion height of the sticker 72 and the wire reel 70 is completely matched, improving adhesion accuracy.

[0049] The anti-detachment block at the top of the vertical slide bar 52 is used to limit the maximum descent stroke of the vertical slide bar 52, preventing the vertical slide bar 52 from detaching from the vertical support 51 and ensuring the safe operation of the equipment. The rotating mechanism 43 and the pushing mechanism 60 are directly mounted at the bottom of the vertical slide bar 52, so that the two move vertically synchronously with the vertical slide bar 52, simplifying the connection relationship of each mechanism.

[0050] like Figure 4 and Figure 5 As shown, preferably, the rotating mechanism 43 includes a first adapter plate 44 and a rotating cylinder 45; one end of the first adapter plate 44 is fixed to the bottom free end of the vertical sliding rod 52, and the other end is equipped with the rotating cylinder 45; the pushing mechanism 60 is equipped on the rotating end of the rotating cylinder 45 and rotates with the rotating cylinder 45.

[0051] Specifically, the core function of the rotating mechanism 43 is to convert the flat sticker 72 into a vertical position. Therefore, a rotary cylinder 45 is selected as the driving component, which has the characteristics of fast response speed and precise rotation angle. The rotary cylinder 45 is fixedly installed on the bottom free end of the vertical sliding rod 52 through the first adapter plate 44 to ensure the connection stability between the rotary cylinder 45 and the vertical sliding rod 52, and to move vertically synchronously with the vertical sliding rod 52.

[0052] The pushing mechanism 60 is directly mounted on the rotating piston end of the rotary cylinder 45. After the rotary cylinder 45 is started, it can drive the pushing mechanism 60 and the paper feeding suction cup 65 to rotate 90°, completing the posture change of the sticker 72 from flat to vertical. The rotary cylinder 45 is preferably an HRQ30 rotary cylinder. This type of cylinder is widely used in the rotary motion control of automated equipment. It has a compact structure, high reliability, and can meet the working conditions of the sticker 72 posture change.

[0053] like Figure 4 and Figure 5As shown, preferably, the pushing mechanism 60 includes a second adapter plate 61, a pushing cylinder 62, a pushing extension rod 63, and a pushing bracket 64; one end of the second adapter plate 61 is fixed to the rotating end of the rotary cylinder 45, and the other end is fitted with the pushing cylinder 62; one end of the pushing extension rod 63 is fixed to the piston end of the pushing cylinder 62, and the other end is fixed to the pushing bracket 64; a plurality of paper feeding suction cups 65 are fixed to the side of the pushing bracket 64 away from the pushing extension rod 63.

[0054] Specifically, The core function of the pushing mechanism 60 is to push the adsorbed sticker 72 towards the wire reel 70. Therefore, a pushing cylinder 62 is selected as the driving component. Its piston end is connected to the pushing extension rod 63 and the pushing bracket 64. The extension and retraction of the piston drives the paper feeding suction cup 65 and the sticker 72 to move forward, realizing the adhesion of the sticker 72 to the enameled wire 71. The pushing cylinder 62 is preferably a guide rod cylinder. This type of cylinder adds a guide rod to the ordinary cylinder, which can effectively prevent shaking and deviation during the movement of the cylinder, ensuring that the sticker 72 is pushed smoothly and accurately, and improving the reliability of the adhesion.

[0055] Because the sticker 72 is relatively large (especially in the length direction), to prevent bending and shaking during the adsorption process, the pusher bracket 64 is equipped with multiple sets of paper feeding suction cups 65: one set at each end of the sticker 72 in the length direction to fix the ends of the sticker 72 and prevent bending; and at least one set in the middle of the sticker 72 in the length direction to support the middle of the sticker 72 and prevent shaking. Preferably, each set of paper feeding suction cups 65 has two cups, adsorbing from both ends of the short side of the sticker 72 to ensure uniform adsorption force.

[0056] The adsorption and release of the paper feeding suction cups 65 adopt a timing control strategy: when adsorbing the sticker 72 in a flat state, all paper feeding suction cups 65 simultaneously adsorb; when pushing the sticker 72 to the coil 70, the first end of the sticker 72 first adheres to the enameled wire 71, and the paper feeding suction cup 65 corresponding to the adsorption head is released first, so that the sticker 72 begins to wind with the rotation of the coil 70; as the sticker 72 is gradually attached, each group of paper feeding suction cups 65 along the production direction is released in sequence, and the sticker 72 that has not approached the coil 70 remains in an adsorbed state to avoid displacement; finally, the paper feeding suction cups 65 at the tail of the sticker 72 are released to ensure that the sticker 72 is completely and flatly attached to the coil 70.

[0057] To address the problem of unstable initial fixation and easy deviation of the sticker tip during sticker application, the paper feeding device of this utility model adopts the following preferred solution: Apply a small amount of low-tack primer to the inner sides of both ends of the sticker (i.e., the side that directly contacts the outer ring of enameled wire on the spool). The primer should be of the "low-tack, residue-free" type, and its adhesion should meet the following requirements: it should be able to quickly adhere to the surface of the enameled wire when applied, forming a transitional fixing effect to prevent the sticker from falling off during the initial stage of spool rotation; at the same time, when the sticker is removed or the spool is reused, the primer should not leave adhesive residue on the surface of the enameled wire or spool, avoiding contamination of the spool or affecting the insulation performance of the enameled wire.

[0058] Furthermore, to control costs and prevent excessive adhesive from overflowing into non-attached areas of the enameled wire, adhesive is applied only to the edges of the sticker, with the application width controlled at 5-10mm. This ensures that the base adhesive only applies to the initial bonding area between the sticker and the enameled wire and does not extend to the middle of the sticker or other areas of the enameled wire.

[0059] With the above setup, after the sticker is transferred to the side of the wire reel by the paper feeding suction cup, the first end can be quickly fixed to the enameled wire by pre-applying base adhesive. Then, it can be continuously wound as the wire reel rotates. The subsequent adhesive application station will cover and reinforce the outer sides of the sticker's first and last ends, thus achieving stable adhesion. This approach also takes into account cost control and product cleanliness.

[0060] Furthermore, it should be noted that the rotating device includes a forward-rotating roller group and a reverse-rotating roller group rotatably connected to the conveying bracket. The rotation direction of the forward-rotating roller group is the same as that of the conveying roller group, and the rotation direction of the reverse-rotating roller group is opposite to that of the conveying roller group. The linear velocities of the forward-rotating roller group, the reverse-rotating roller group and the conveying roller group are equal, and the roller surface heights of the forward-rotating roller group and the reverse-rotating roller group are adapted to the roller surface heights of the conveying roller group, so that while the coil is conveyed forward under the drive of the conveying roller group, it rotates around its own axis under the cooperation of the forward-rotating roller group and the reverse-rotating roller group.

[0061] The linear velocities of the conveyor roller group, the forward-rotating roller group, and the reverse-rotating roller group must be strictly synchronized (linear velocity = roller circumference × rotational speed). For example, if the linear velocity of the conveyor roller group is... Then the linear speeds of the forward and reverse roller sets also need to be set to... This ensures that the friction at the top and bottom of the coil does not impede or accelerate the conveying process as it moves forward, generating only rotational force around its own axis. To achieve linear speed synchronization, the rotational speeds of the conveyor roller group, the forward-rotating roller group, and the reverse-rotating roller group must be matched according to their respective roller diameters. Assuming the conveyor roller group's roller diameter is D1, the forward-rotating roller group's short roller diameter is D2, and the reverse-rotating roller group's short roller diameter is D3, then the following conditions must be met: ,in These represent the rotational speeds of the conveyor roller group, the forward-rotating roller group, and the reverse-rotating roller group, respectively, in r / min.

[0062] Through the above design, the reel is stably conveyed forward along the production direction under the drive of the conveyor roller group. At the same time, under the action of the reverse friction of the forward and reverse roller groups, it rotates synchronously around its own axis, ultimately realizing the composite motion of "conveying + rotation" to meet the process requirements of automatic sticker application.

[0063] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
