Description

TECHNICAL FIELD

[0001] The utility model relates to winding packaging technical field, concretely relates to a kind of rubberizing subassembly, adhesive tape pasting device and winding machine. BACKGROUND

[0002] In the packaging technical field, it is extremely important to wrap objects with adhesive tape. Non-whole-circle winding of adhesive tape can achieve sealing of the wrapped objects (such as paper boxes, turnover boxes, and objects with certain shapes), while whole-circle winding can increase the sealing strength or enhance the strength of the entire wrapped object, which helps to ensure the integrity of the wrapped object during transportation and storage, preventing the object from scattering or being damaged. With the vigorous development of the logistics industry and the increasing demand for product packaging, higher requirements are placed on the performance and efficiency of adhesive tape winding equipment.

[0003] Currently, most adhesive tape automatic winding machines on the market have the function of automatically sticking the head / tail end of the adhesive tape to the wrapped object. For example, the publication number CN217295123U “A smoothing mechanism of a winding packaging machine” uses a rotating leveling pad to stick the end of the adhesive tape to the wrapped object in a flipping and patting manner. However, since the flipping and patting force is needed to pull down the end of the adhesive tape that is originally stuck to the glue receiving structure, a sufficient patting force is required to ensure that the end of the adhesive tape is pulled down. However, if the force is not controlled properly, it may cause damage to the wrapped object. In addition, the leveling pad can only pat a part of the adhesive tape, and the parts that are not in contact may not be completely stuck, which may cause dust or other substances to adhere to the wrapped object during subsequent turnover.

[0004] In addition, in the prior art, the patent with publication number CN116443352A “Improved adhesive tape sealing and packaging machine” applied for in 2023 discloses a brush mounted on a swinging telescopic rod, which is driven to rotate by the rotation of the telescopic rod. The telescopic structure of the telescopic rod ensures the translation and rubbing of the brush at the bottom of the wrapped object, achieving the scheme of completely sticking the end of the adhesive tape to the bottom of the wrapped object regardless of its length. However, this method requires a large enough extrusion force for the brush to pull the end of the adhesive tape from the glue receiving structure, so the brush is prone to deformation. Moreover, the telescopic rod is susceptible to shaking and instability due to the stress on the cantilever end. To solve this problem, the patent with publication number CN118811209A “Adhesive tape automatic sealing and packaging machine” of the same inventor as the above-mentioned technology was applied for and disclosed in 2024. This technology improves the structure of the adhesive tape sticking. The brush for sticking the adhesive tape no longer uses a swinging and telescopic method, but instead uses a structure consisting of a sliding plate, a guide rod, a sliding block, and a tension spring to ensure the smooth movement of the brush, thereby prolonging the service life of the adhesive tape sticking structure. However, this structure is more complex and reduces reliability, and the problem of brush deformation and damage remains unsolved. Utility Model Content

[0005] The present invention aims to provide an adhesive application component to solve the problems of existing technologies that cannot achieve complete adhesion of the tape end by flipping and patting, while the tape application method by brushing and sliding has a complex structure and its components are easily damaged.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adhesive application assembly includes a rocker arm, an adhesive application arm rotatably connected to the cantilever section of the rocker arm, an adhesive application wheel rotatably connected to the cantilever section of the adhesive application arm, the adhesive application wheel being used to apply adhesive tape to the object being wrapped, and an adhesive application elastic element connected between the adhesive application arm and the rocker arm, the adhesive application elastic element allowing the adhesive application arm to maintain a set angle with the rocker arm in a free state.

[0008] The principle and advantages of this solution are as follows: The adhesive applicator in this solution is used to apply the end of the tape to the surface of the object being wrapped. When this solution is in use, the adhesive arm is rotated by the swing arm. As the swing arm moves the adhesive arm closer to the tape to be pasted, the adhesive roller gradually comes into contact with the tape. After the adhesive roller comes into contact with the tape, the swing arm continues to rotate to shorten the distance between the object being wrapped and the adhesive arm. The adhesive roller on the adhesive arm and the object being wrapped will then be in contact through the tape. At this time, as the distance between the adhesive arm and the object being wrapped continues to get closer, the adhesive roller will press the adhesive arm to overcome the elastic force of the adhesive elastic element, so that the adhesive roller presses the tape onto the surface of the object being wrapped. Because of the presence of the adhesive elastic element, the adhesive roller can adapt to whether the tape pasting position of the object being wrapped is straight, curved, or has pits, thus achieving a smooth pasting of the tape on the surface of the object being wrapped.

[0009] This solution, with its adhesive arm, adhesive elastic component, and adhesive roller, still employs a swing mechanism but eliminates the need for a telescopic mechanism, enabling the adhesive roller to adhere the tape end. The entire structure is very simple.

[0010] Furthermore, during the tape application process, as the lever drives the tape application arm closer to the object being wrapped, the pressure exerted by the tape application wheel on the remaining tape gradually increases under the action of the tape application elastic element. This pressure allows the tape end attached to the adhesive structure to be pulled off, and the tape end is gradually and completely pressed onto the surface of the object being wrapped by the movement of the tape application wheel with the lever. The gradual increase in pressure during this process ensures that the tape adheres tightly to the surface of the object being wrapped. In addition, because the contact between the tape application wheel and the object being wrapped is always affected by the tape application elastic element, the angle of the tape application arm relative to the lever can be adaptively adjusted. Therefore, the entire tape application assembly is not easily damaged, and compared with existing tape application structures with brushes, this solution has a longer service life.

[0011] Preferably, the rubberized wheel is a rubberized roller, so as to reduce the friction of the rubberized process, improve the quality of the rubberized and help prolong the service life of the rubberized assembly by rolling of the roller structure.

[0012] Preferably, the rubberized elastic member is a torsion spring, the rubberized elastic member is sleeved on the rotating shaft of the rubberized arm, two limiting portions are arranged on one of the swing lever and the rubberized arm, and two pushing portions are arranged on the other one, the two limiting portions and the two pushing portions are located on the same side of the two torsion arms of the rubberized elastic member, and the length of each torsion arm can span the limiting portion and the pushing portion.

[0013] Preferably, the swing lever is a bent swing lever / arc-shaped swing lever, the bent / arc-shaped structure of the swing lever is used for avoiding the glue receiving structure of the winding machine, and the rubberized wheel is used for making the stroke of the rubberized wheel exceed the projection position of the cutting knife on the winding object after the swing lever swings, so as to completely flatten and rubberize the rubber band which is obliquely pulled on the winding object and the glue receiving assembly and to be rubberized to exceed the projection position of the cutting knife on the winding object.

[0014] The utility model also provides a rubber band rubberizing and cutting device, including the rubberized assembly, still include cutting assembly for cutting rubber band, cutting assembly has cutting knife.

[0015] Preferably, the number of the rubberized assembly is two, one is used for pasting the head section of the rubber band and the other is used for pasting the tail section of the rubber band, and the two rubberized assemblies are symmetrical in structure and are located on the two sides of the cutting assembly.

[0016] Preferably, the cutting assembly further comprises an energy storage elastic member and a limiting member, the cutting knife is rotationally connected to the rack, the energy storage elastic member is connected between the cutting knife and the rack, the energy storage elastic member is used for giving the cutting knife a force close to the winding object, and the limiting member is used for limiting the rotation of the cutting knife after the energy storage of the energy storage elastic member is completed.

[0017] Preferably, the limiting member is rotationally connected to the rack, a pushing elastic member is further connected between the limiting member and the rack, and the pushing elastic member is used for locking the limiting member and the cutting knife; one of the limiting member and the cutting knife is provided with a limiting structure, and the other is provided with a matching structure, the limiting structure and the matching structure can be abutted or can be concave-convex matched;

[0018] A trigger is connected between the rubberized assembly for pasting the tail end of the rubber band and the cutting device, the trigger comprises a cable, one end of the cable is connected to the cantilever end of the limiting member, and the other end of the cable can be driven by the rotation of the swing lever.

[0019] Beneficial effect: the energy storage elastic element is used for storing energy of the cutting knife, and the energy storage is released only after the tail sticking and gluing assembly is started, and the corresponding swing rod swing can pull the cable, so that the cable drives the limiting part to rotate to overcome the elastic potential energy of the pushing elastic element, thereby realizing the rotation limiting release of the cutting knife, and achieving automatic cutting control when the adhesive tape needs to be cut.

[0020] Preferably, the adhesive tape sticking device further comprises an adhesive tape connecting assembly located between the two adhesive tape sticking assemblies, the adhesive tape connecting assembly comprising an adhesive tape connecting arm, an adhesive tape connecting roller mounted on the adhesive tape connecting arm, and a stopper for limiting rotation of the adhesive tape connecting roller, the adhesive tape connecting arm being used for moving away from or approaching the winding object, and the adhesive tape connecting arm moving away from the winding object drives the cutting knife to move away from the winding object.

[0021] Beneficial effect: when the adhesive tape on the winding machine starts to stick to the winding object, in order to ensure that the end of the adhesive tape is fixed on the adhesive tape connecting roller, the rotation of the adhesive tape connecting roller approaching the winding object is limited by the stopper, that is, the adhesive tape connecting roller cannot rotate, so that the end of the adhesive tape is tightly stuck to the adhesive tape connecting roller, thereby achieving the required force for winding the adhesive tape; when the end of the adhesive tape needs to be stuck to the winding object, the adhesive tape connecting arm is controlled to move away from the winding object, so that the adhesive tape connecting roller can rotate freely, and the adhesive tape connecting roller can automatically rotate to easily separate the end of the adhesive tape from the adhesive tape connecting roller, thereby solving the problem that the end of the adhesive tape is fixed to facilitate winding of the adhesive tape, and the adhesive tape needs to be easily separated during adhesive removal, and the two use cases cannot be considered.

[0022] In addition, in the present application, the retraction movement of the adhesive tape connecting arm away from the winding object drives the cutting knife to move away from the winding object, so that the energy storage elastic element accumulates elastic potential energy for subsequent cutting, and a separate driving mechanism for the cutting assembly is not needed, which helps to reduce costs and save energy.

[0023] The utility model discloses still provide a kind of winding machine, including the adhesive tape sticking and cutting device, further include the winding mechanism for driving film to move circumferentially. BRIEF DESCRIPTION OF DRAWINGS

[0046] The following detailed description illustrates the specific implementation method:

[0047] The reference numerals in the accompanying drawings include: frame 10, adhesive application assembly 100, swing arm 11, adhesive application arm 12, adhesive application roller 13, adhesive application elastic element 14, limit pin 111, push ring 121, cable 101, connecting rod 102, trigger drive wheel 103, trigger roller 104, trigger lever 105, adhesive receiving assembly 200, adhesive receiving arm 21, wedge surface 211, adhesive receiving roller 22, stopped element 221, movable roller 23, stop element 24, cutting assembly 300, drive wheel 31, drive rod 311, cutting arm 32, cutter 33, energy storage elastic element 34, limit element 35, pushing elastic element 36, brush 37, winding mechanism 400, cargo platform 500, and object to be wound 600.

[0048] Example 1

[0049] Combination Figures 1 to 6As shown, a rubberizing assembly 100 includes a swing lever 11, a rubberizing arm 12 and a rubberizing roller 13. The swing lever 11 is rotatably connected to a frame 10, and the rotation of the swing lever 11 is driven by a separate rubberizing drive machine (not shown in the drawing). The swing lever 11 is rotatably connected to the rubberizing arm 12 at the cantilever end of the swing lever 11. The rubberizing arm 12 is rotatably connected to the rubberizing roller 13 at the cantilever end of the rubberizing arm 12. The rubberizing roller 13 is used to paste the adhesive tape on the winding object. The rubberizing arm 12 is connected to the swing lever 11 by a rubberizing elastic member 14. The rubberizing elastic member 14 keeps the rubberizing arm 12 at a set angle with the swing lever 11 in a free state. That is, the rubberizing arm 12 needs to be pushed by an external force and overcome the elastic force of the rubberizing elastic member 14 to rotate relative to the swing lever 11.

[0050] In one embodiment, the rubberizing elastic member 14 is a torsion spring, and the rubberizing elastic member 14 is sleeved on the rotating shaft of the rubberizing arm 12. One of the swing lever 11 and the rubberizing arm 12 is provided with two limiting portions, and the other is provided with two pushing portions. The two limiting portions and the two pushing portions are located on the same side of the two torsion arms of the rubberizing elastic member 14, and the length of each torsion arm can span the limiting portion and the pushing portion. In a specific embodiment, the limiting portion is two limiting pins 111, and the pushing portion is two pushing surfaces on a pushing ring 121. The two limiting pins 111 are fixed on the cantilever end of the swing lever 11, and the pushing ring 121 with the pushing surfaces is fixed on the rubberizing arm 12. Thus, the rubberizing elastic member 14, the limiting portion and the pushing ring 121 are conveniently installed, and the rubberizing arm 12 can meet the clockwise or counterclockwise rotation requirement after being pushed by an external force.

[0051] Through the rubberizing assembly 100, when the rubberizing arm 12 approaches the winding object under the driving of the swing lever 11, the rubberizing roller 13 gradually contacts the adhesive tape. Then, the swing lever 11 is continuously rotated to make the rubberizing arm 12 closer to the winding object, and the rubberizing roller 13 presses the adhesive tape to the surface of the winding object. Due to the existence of the rubberizing elastic member 14, the rubberizing roller 13 can adapt to the shape of the surface of the winding object (such as flat, curved or concave), so as to realize the flat pasting of the adhesive tape. In addition, the rubberizing roller 13 presses the adhesive tape twice, so that the head of the adhesive tape can be tightly pasted after winding.

[0052] In the process of pasting the adhesive tape, as the swing lever 11 drives the pasting arm 12 to approach the winding object, the extrusion force of the pasting roller 13 on the adhesive tape that has not been pulled off will gradually increase. This increasing extrusion force can make the end of the adhesive tape be separated under extrusion and gradually be completely pressed and pasted onto the surface of the winding object as the pasting roller 13 moves with the swing lever 11. This process not only realizes automatic increase of the extrusion force, but also uses the increasing extrusion force to make the adhesive tape tightly adhere to the surface. In addition, as the contact between the pasting roller 13 and the winding object is always affected by the pasting elastic member 14, the angle of the pasting arm 12 can be adaptively adjusted.

[0053] In one embodiment, in order to enable the end of the adhesive tape to exceed the cutting projection position of the cutter 33 after being pressed and pasted by the pasting roller 13, the swing lever 11 is a bent swing lever 11 / arc swing lever 11. The bent / arc configuration of the swing lever 11 is used to avoid the adhesive tape being pulled obliquely between the winding object and the adhesive receiving assembly 200 of the winding machine. After the swing lever 11 swings, the pasting roller 13 is located between the adhesive receiving assembly 200 and the winding object, and the stroke of the pasting roller 13 exceeds the projection position of the cutter on the winding object, so that the adhesive tape that is obliquely pulled between the winding object and the adhesive receiving assembly 200 is completely flattened on the winding object and the pressed and pasted length exceeds the projection position of the cutter 33 on the winding object. Under the symmetrical arrangement of the head pasting adhesive assembly 100 and the tail pasting adhesive assembly 100, the overlapping of the adhesive tape on the winding object is finally realized, and the winding strength of one winding of the adhesive tape is ensured.

[0054] In summary, the pasting assembly 100 of the present embodiment not only has simple structure and high reliability, but also has strong adaptability, high durability, and can conveniently realize the overlapping of the head and tail sections of the adhesive tape (as shown in Figure 3 , and improve the winding strength.

[0055] Embodiment Two

[0056] In combination Figure 7 , the present embodiment provides an adhesive tape pasting and cutting device, which comprises two pasting assemblies 100 of embodiment one, and further comprises an adhesive receiving assembly 200 and a cutting assembly 300. The adhesive receiving assembly 200 and the cutting assembly 300 are located between the two pasting assemblies 100, and the two pasting assemblies 100 are structurally symmetrical. One of the pasting assemblies 100 is used for pasting the head section of the adhesive tape (referred to as a head pasting adhesive assembly 100, which is located on the left side in the drawings), and the other pasting assembly 100 is used for pasting the tail section of the adhesive tape (referred to as a tail pasting adhesive assembly 100, which is located on the right side in the drawings).

[0057] The adhesive receiving assembly and the cutting assembly will be described below respectively.

[0058] I. Adhesive Receiving Assembly 200

[0059] In combination Figures 7 to 12The glue receiving assembly 200 comprises a glue receiving driving machine, a glue receiving arm 21, a glue receiving roller 22, a movable roller 23 and a stopper 24. The glue receiving arm 21 is slidingly connected to the frame 10. The glue receiving roller 22 and the movable roller 23 are installed on the glue receiving arm 21 and can freely rotate around their own centers. The glue receiving driving machine drives the glue receiving arm 21 to move axially along the glue receiving roller 22. The glue receiving arm 21 can move away from or approach the object to be wound under the driving of the glue receiving driving machine. After the glue receiving arm 21 approaches the object to be wound, the glue receiving roller 22 and the movable roller 23 are located within the enclosed range of the circumferential movement of the adhesive roll on the winding machine. The glue receiving driving machine can be a reciprocating linear module, a linear driving structure, a linear electric cylinder, a linear air cylinder or other pneumatic / electrical driving structures that can drive the glue receiving arm 21 to move linearly.

[0060] The stopper 24 is fixedly installed on the frame 10 and is used to limit the free rotation of the glue receiving roller 22 (the movable roller 23 can not be restricted by the stopper 24). The stopper 24 can realize the braking of the glue receiving roller 22. In one embodiment, a plurality of stoppers 221 are fixed on the glue receiving roller 22 and can abut against or concave-convex fit with the stopper 24. In the drawings, the stopper 24 is a reed and the stoppers 221 are polygonal abutting sleeves fixed on the glue receiving roller 22. The abutting sleeves are used to abut against the reed when the glue receiving arm 21 approaches the object to be wound to a certain position, so as to limit the free rotation of the glue receiving roller 22 by abutment.

[0061] The movable roller 23 is parallel to the glue receiving roller 22. The movable roller 23 and the glue receiving roller 22 reserve a cutting space for the cutting knife 33 of the winding machine.

[0062] When the winding machine starts to wind, the end of the adhesive tape is pasted on the glue receiving roller 22 stopped by the stoppers 221. With the circumferential movement of the adhesive roll, the adhesive tape is pulled out. The glue receiving roller 22 that cannot rotate in this process can ensure that the end of the adhesive tape is fixed on the glue receiving roller 22 and does not come off. When the winding is completed, the adhesive tape is transversely arranged on the glue receiving roller 22 and the movable roller 23. The glue receiving roller 22 that is limited in rotation by the stopper 24 can fix the adhesive tape thereon and prevent the adhesive tape from being loosened with the cutting of the cutting knife, so as to prepare for the next winding.

[0063] When the end of the adhesive tape needs to be pasted on the object to be wound, the glue receiving arm 21 is controlled to move, so that the stopper 24 releases the rotation limitation of the glue receiving roller 22. When the end of the adhesive tape is pressed, flattened and pasted, the end of the adhesive tape can easily rotate the glue receiving roller 22 and come off the glue receiving roller 22.

[0064] Therefore, the embodiment can realize the effect that the end of the adhesive tape can be tightly pasted on the glue receiving roller 22 in the initial winding to facilitate the winding of the adhesive tape and can be easily detached from the glue receiving roller 22 when the adhesive tape is detached.

[0065] In addition, the setting of the movable roller 23 parallel to the glue receiving roller 22 makes the glue tape adhere between the glue receiving roller 22 and the movable roller 23 when the glue tape needs to be cut off, and the cutting knife 33 of the winding machine extends into the two rollers to quickly and easily cut off the glue tape. The head end of the cut glue tape adheres to the glue receiving roller 22, and the tail end of the cut glue tape adheres to the movable roller 23, which facilitates the subsequent pressing and smoothing of the tail end of the glue tape wound on the object to be wound. Since the tail end of the glue tape adheres to the movable roller 23 which can rotate freely, the tail end of the glue tape can easily fall off during the pressing and smoothing process, thereby ensuring that the tail end of the glue tape can be smoothly adhered to the object to be wound.

[0066] II. Cutting assembly 300

[0067] In combination Figures 7 to 12 The cutting assembly 300 includes a driving wheel 31, a cutting arm 32, a cutting knife 33, an energy storage elastic member 34, and a limiting member 35. The driving wheel 31 is fixed with a driving rod 311, and the glue receiving arm 21 pushes the driving rod 311 to rotate during the process of moving away from the object to be wound. The cutting arm 32 is rotationally connected to the frame 10, and the cutting arm 32 is coaxially fixed with a driven wheel. The driving wheel 31 and the driven wheel are connected in a gear transmission mode. The cutting knife 33 is installed on the cantilever section of the cutting arm 32. The energy storage elastic member 34 is connected between the cutting arm 32 and the frame 10. The energy storage elastic member 34 is installed on the cantilever ends of the cutting arm 32 in different directions. The energy storage elastic member 34 is used to give the cutting arm 32 a force close to the object to be wound. The energy storage elastic member 34 is energized after the frame 10 moves away from the object to be wound. In this embodiment, the limiting member 35 is used to limit the rotation of the driving wheel 31 after the energy storage elastic member 34 is energized. In this embodiment, the energy storage elastic member 34 is a spring. Of course, the rotation of the driven wheel is also limited by the limiting member 35, which can limit the release of the elastic potential energy of the cutting assembly 300. Since the driven wheel and the driving wheel 31 are both wheel structures, the limiting method can be the same, so this embodiment will not be described in detail for the limiting scheme of the driven wheel.

[0068] Specifically, the limiting member 35 is rotationally connected to the frame 10, and the pushing elastic member 36 is further connected between the limiting member 35 and the frame 10. The pushing elastic member 36 is used to provide a force to the limiting member 35 towards the driving wheel 31. In this embodiment, the pushing elastic member 36 is a spring.

[0069] In one embodiment, the rotation of the driving wheel 31 is limited by the limiting member 35 in a mechanical contact mode. Specifically, in combination Figure 12The limiting member 35 and the driving wheel 31 are provided with a limiting structure and a matching structure respectively, the limiting structure and the matching structure can abut or concave-convex match, in the drawings of the embodiment, the limiting member 35 is provided with a limiting hook, the driving wheel 31 is machined with a convex matching surface, the limiting hook and the abutting surface can abut / hook, when the two abut, the driving wheel 31 is limited; of course, the limiting structure and the matching structure can also be a concave groove and a convex matching, the limiting is realized through the concave-convex matching. When the driving wheel 31 needs not to be limited by the limiting member 35, the limiting of the limiting member 35 on the driving wheel 31 is released.

[0070] In order to reduce the contact wear between the glue arm 21 and the driving rod 311 and prolong the service life, a driving wheel is installed at the cantilever end of the driving rod 311, and the glue arm 21 is provided with a wedge surface 211 abutting against the driving wheel. The glue arm 21 retreats through the wedge surface 211 to push the driving wheel to roll, the driving wheel drives the driving rod 311 to swing, and the driving wheel 31 rotates.

[0071] In order to make the adhesive tape close to the glue roller 22 and the movable roller 23 when the adhesive tape is cut, two brushes 37 / elastic plates are also fixed on the cutting arm 32, the brushes 37 / elastic plates are used to abut against the glue roller 22 to press the adhesive tape, the elastic plate has a structure of elastic material that can be compressed and restored, such as a silica gel plate, a rubber plate, etc., in the drawings of the embodiment, only the mode of the brush 37 is shown.

[0072] When the adhesive tape head end is pasted on the winding object, the swing rod 11 of the head-end pasting and gluing assembly 100 (the left pasting and gluing assembly 100 in the drawings) is controlled to rotate, so as to drive the corresponding glue arm 12 to approach the winding object, and the glue roller 13 on the glue arm 12 also gradually approaches the adhesive tape and the winding object; with the continuous rotation of the swing rod 11, the distance between the glue arm 12 and the winding object becomes closer and closer, the glue roller 13 presses the adhesive tape to the surface of the winding object and tears off the adhesive tape head end originally pasted on the glue roller 22; the rotation of the swing rod 11 is continuously controlled until the glue roller 13 pastes all the torn-off adhesive tape on the winding object, and the pasting of the adhesive tape head end is completed.

[0073] When the winding number of the adhesive tape meets the requirement, the tail-end pasting and gluing assembly 100 (the right pasting and gluing assembly 100 in the drawings) is started, and the corresponding swing rod 11 drives the glue roller 13 at the end of the glue arm 12 to paste the tail end of the adhesive tape. In this process, the limiting member 35 of the cutting assembly 300 is controlled to release the limitation to release the elastic potential energy (such as Figure 10 The cutting knife 33 rotates under the pushing of the elastic force to cut off the adhesive tape, and the tail-end pasting and gluing assembly 100 continues to drive the corresponding glue roller 13 to paste the adhesive tape until the tail end of the adhesive tape is pasted.

[0074] After the end of the adhesive tape is pasted, the adhesive assembly 200 is driven by the adhesive drive machine to move back to move away from the winding position of the winding object. The back movement of the adhesive arm 21 is achieved by the wedge surface 211 pushing the driving wheel and the driving rod 311 to rotate, so that the cutting knife 33 is driven away from the winding object by the driving wheel 31 - the driven wheel - the cutting arm 32, and the energy storage elastic member 34 is prepared for the next cutting assembly 300 to cut the adhesive tape (to Figure 12 the state shown).

[0075] Embodiment three

[0076] In combination Figures 17 to 18 , this embodiment three is improved on the basis of embodiment two, as follows:

[0077] The connecting trigger between the tail pasting adhesive assembly 100 and the cutting assembly 300, the trigger includes a cable 101, one end of the cable 101 is connected to the cantilever end of the limiting member 35, the other end of the cable 101 can be driven by the rotation of the swing rod 11, after the swing rod 11 starts to paste the tail of the adhesive tape, the swing rod 11 swings a certain angle, which pulls the cable 101, so that the limiting member 35 overcomes the elastic force of the pushing elastic member 36, and the elastic potential energy of the cutting assembly 300 is released, the cutting knife 33 is close to the winding object and then cuts the adhesive tape.

[0078] The specific implementation can be as follows: in combination Figures 18 to 22The trigger further comprises a connecting rod 102, a trigger driving wheel 103, a trigger roller 104 and a trigger lever 105, the trigger driving wheel 103 is rotationally connected to the frame 10, the trigger lever 105 is rotationally connected to the frame 10, one end of the connecting rod 102 is rotationally connected to an eccentric position of the trigger driving wheel 103, the other end of the connecting rod 102 is rotationally connected to an eccentric position of the swing rod 11, the connecting rod 102 is connected to two ends of the swing rod 11 respectively via the rubberizing arm 12, so that when the rubberizing driving machine drives any one of the swing rod 11 or the trigger driving wheel 103 to rotate, the swing rod 11 and the trigger driving wheel 103 can rotate around themselves through the connecting rod 102, in the embodiment, the rubberizing driving machine can be a driving motor which drives the swing rod 11 to swing around itself or drives the trigger driving wheel 103 to swing around itself, when the rubberizing driving machine is the driving motor which drives the trigger driving wheel 103 to rotate, the swing rod 11 can have a larger torque through the cooperation of the connecting rod 102 and the swing rod 11, so that the required torque for pressing and pasting can be achieved without increasing the speed reducer. Of course, the rubberizing driving machine can also be a structure in which a cylinder is used as a driving source to drive the swing rod 11 to swing around itself or drive the trigger driving wheel 103 to swing around itself, for example, the cylinder is used as the driving source of the rubberizing driving machine, the cylinder body is rotationally connected to the frame 10, the swing mode driven by the cylinder is prior art, and the present embodiment is only briefly described, for example, the piston rod end of the cylinder is rotationally connected to an eccentric position of the swing rod 11 / an eccentric position of the trigger driving wheel 103.

[0079] In this way, one end of the pull cable 101 is connected to the limiting piece 35, and the other end is connected to the trigger lever 105, the end of the trigger lever 105 away from the connection of the pull cable 101 can drive the trigger roller 104 to push the trigger lever 105 after the trigger driving wheel 103 rotates, so as to drive the pull cable 101 to pull the limiting piece 35 away from the driving wheel 31, and the elastic potential energy of the cutting assembly 300 is released as the limiting piece 35 overcomes the elastic force of the pushing elastic piece 36.

[0080] In addition, in this way, in order to make the pull cable 101 pull more smoothly and the installation structure more compact, a fixed pulley is installed on the frame 10, so that after the one end of the pull cable 101 is connected to the limiting piece 35, it needs to pass through the fixed pulley and then be connected to the trigger lever 105.

[0081] The second way is to combine Figures 17 to 19, the cable 101 is connected to the cantilever end of the limiting part 35 by bypassing the fixed pulley, and the other end is installed on the rack 10, when the adhesive arm 12 is driven by the swing lever 11 to approach the object to be wound, the swing lever 11 is swung to pull the cable 101, so as to drive the limiting part 35 to overcome the elastic force of the pushing elastic part 36, and then release the rotation limitation of the driving wheel 31, so as to achieve the purpose of active cutting of the cutter 33 under the elastic potential, the whole structure is simple and convenient, and the swing power during the pressing and pasting of the adhesive tape is used to realize the mechanical automatic control cutting, which is also helpful to save energy and reduce consumption.
