Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of winding packaging, in particular to a tape sticking device, a winding machine and a use method. BACKGROUND

[0002] In the field of packaging technology, it is extremely important to use adhesive tape to wrap objects. Non-entire-circle winding of adhesive tape can achieve sealing of the wrapped objects (such as cartons, turnover boxes, and packaged objects with certain shapes), while entire-circle winding can increase the sealing strength or enhance the strength of the entire packaged object, which helps to ensure the integrity of the wrapped objects during transportation and storage, preventing the objects from falling apart or being damaged. With the rapid 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, automatic adhesive tape winding machines on the market are generally equipped with automatic tape connecting function, automatic pressing and sticking function of the head and tail of the adhesive tape. Specifically, when starting to wind, the end of the adhesive tape is pasted on the tape connecting structure, and the adhesive tape is smoothly pulled out by the circumferential movement of the adhesive tape roll. The pulled-out adhesive tape is pasted on the wrapped object along with the movement of the adhesive tape roll. The end of the adhesive tape pasted on the tape connecting structure needs to be hard pulled by the pressing structure and then pasted on the wrapped object.

[0004] However, the existing technology has the problem of insufficient stability of the mechanism. In the initial winding stage, the end of the adhesive tape must be tightly attached to the tape connecting structure to ensure that the adhesive tape is smoothly pulled out when the adhesive tape roll moves circumferentially. In the pressing stage, the end of the adhesive tape in the straightened state needs to be forcibly pulled off by the pressing structure. Since the viscosity of the adhesive tape varies, it cannot be guaranteed that the viscosity of the adhesive tape used each time is the same, so the pulling force when the adhesive tape is hard pulled off is not the same, which affects the stability of the mechanism.

[0005] On the other hand, the existing technology also has the risk of adhesive tape retraction causing adhesion. After the adhesive tape is hard pulled off, the adhesive tape suddenly relaxes from the straightened state, which is easy to cause the end to stick due to elastic retraction.

[0006] For example, patent No. CN218506200U “Adhesive tape winding device” connects the adhesive tape through an adhesive tape limiting plate, and for example, patent No. CN217295123U “Smoothing mechanism of winding packaging machine” connects the adhesive tape through an adhesive tape connecting rod fixed on a swing arm.

[0007] In view of the problems existing in the glue connection, the prior art has another way, such as the patent with the publication number CN118811209A "Automatic box sealing and packaging machine of adhesive tape" applied and disclosed in 2024, which discloses that the clamping or loosening of the adhesive tape by the first lever and the connecting seat can meet the functional requirements of glue connection and degumming, but in this technology, the first lever and the connecting seat are in contact with the adhesive tape through a plane, and when the adhesive tape is clamped on the first lever and the connecting seat, it will still be in surface contact with one of the parts. Even when the two parts are separated from each other, it is still necessary to pull the adhesive tape down by hard pulling, so the above-mentioned problems cannot be solved. The patent with the publication number CN112441293A "Rotary ring surrounding type adhesive tape box sealing and packaging machine" of the same inventor as the above patent sets up an adhesive tape push plate to solve the problem of difficult degumming, but the adhesive tape push plate is connected with a spring, and the adhesive tape push plate is also provided with a convex rib and a concave and convex tooth. The rotation of the lever drives the concave and convex tooth on the adhesive tape push plate to push the adhesive tape downward to reduce the difficulty of degumming, but this way also has the problem of complex structure.

[0008] In addition, the current pasting of the head and tail ends of the adhesive tape on the wrapped object also has some problems. The common methods are the beating and pressing method and the moving and smoothing method:

[0009] The first beating and pressing method: such as the patent with the publication number CN217295123U "Smoothing mechanism of winding packaging machine", which uses a rotating leveling pad to paste the end of the adhesive tape on the wrapped object in a flipping and beating manner. However, the flipping and beating force needs to pull down the adhesive tape end that is originally pasted on the glue connection structure, so the beating force needs to be enough to ensure that the adhesive tape end 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 beat part of the adhesive tape area, and the parts that are not in contact may not be pasted, and may stick dust or other substances during the subsequent turnover of the wrapped object.

[0010] The second moving flattening method: such as the patent with the publication number CN116443352A "Improved adhesive tape sealing packaging machine" applied in 2023, which discloses installing a brush on a swing telescopic rod, and driving the rotation of the brush by the rotation of the telescopic rod, and at the same time, the telescopic structure of the telescopic rod ensures the translation rubbing of the brush at the bottom of the winding object, realizing the scheme that the adhesive tape end can be completely pasted at the bottom of the winding object regardless of its length or short. However, this method requires a large enough extrusion force for the brush to pull the adhesive tape end off the adhesive structure, so the brush is easily deformed. In addition, the sleeve structure of the telescopic rod is stressed at the cantilever end, and the telescopic rod is prone to shaking and instability during use. To solve this problem, the patent with the publication number CN118811209A "Automatic adhesive tape sealing packaging machine" of the same inventor as the above-mentioned technology was applied and disclosed in 2024. This technology improves the pasting structure of the adhesive tape. The brush for pasting the adhesive tape no longer uses a swing and telescopic method, but sets up a slide plate, a guide rod, a slide block, a tension spring, and other structures to ensure the smooth movement of the brush, thereby prolonging the service life of the adhesive structure. However, this structure is more complex, reducing reliability, and the problem of easy deformation and damage of the brush still cannot be solved. SUMMARY

[0011] The present application aims to provide an adhesive tape pasting device to realize that the adhesive tape end can be tightly adhered to the adhesive structure at the initial winding stage and easily detached from the adhesive structure when the adhesive structure pulls the adhesive tape.

[0012] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0013] An adhesive tape pasting device includes an adhesive component and a pasting component installed on a rack. The number of pasting components is two, one is a head pasting component, and the other is a tail pasting component. The adhesive component is located between the two pasting components. The adhesive component includes an adhesive arm, an adhesive roller installed on the adhesive arm, and a stopper for limiting the rotation of the adhesive roller. The adhesive arm is slidingly connected to the rack and is used to move away from or approach the winding object.

[0014] The principle and advantages of the present scheme are: when the adhesive tape on the winding machine starts to stick to the object to be wound, in order to ensure that the end of the adhesive tape is fixed on the glue receiving roller, at this time the glue receiving roller close to the object to be wound is limited to rotate by the stopper, so that the glue receiving roller cannot rotate, ensuring that the end of the adhesive tape is tightly attached to the glue receiving roller, so as to achieve the required force when the adhesive tape is wound; when the adhesive tape needs to be attached to the object to be wound by the adhesive attaching assembly, the glue receiving arm is controlled to move, so that the glue receiving roller can be separated from the stopper to brake the glue receiving roller, so that the glue receiving roller can rotate freely. When the glue receiving arm drives the glue receiving roller away from the object to be wound, the glue receiving roller will automatically rotate to make the adhesive attaching assembly easily separate the end of the adhesive tape from the glue receiving roller, solving the problem that in the prior art, the end of the adhesive tape needs to be fixed to facilitate winding of the adhesive tape, and the adhesive tape needs to be easily separated from the glue receiving structure when the adhesive tape is detached, which cannot be considered in both cases.

[0015] In addition, the present scheme can switch the glue receiving roller between free rotation and limited rotation through the stopper, thereby reducing the viscosity requirement of the adhesive tape. Whether the adhesive tape has low viscosity or high viscosity, the end of the adhesive tape can be fixed when needed, and the glue receiving roller can rotate to facilitate the separation of the adhesive tape under small extrusion force when the end of the adhesive tape needs to be separated, which helps to improve the stability of the mechanism of the adhesive attaching assembly and the adhesive attaching structure.

[0016] Preferably, the stopper is fixedly installed, and the glue receiving roller is fixed with a stopper, and the stopper and the stopper can abut or concave-convex cooperate.

[0017] Preferably, the stopper is a reed, and the stopper is a polygon abutting sleeve fixed on the glue receiving roller, and the abutting sleeve is used to abut the reed.

[0018] Preferably, the glue receiving arm is provided with a movable roller, and the movable roller and the glue receiving roller are used to paste the adhesive tape, and the movable roller and the glue receiving roller reserve a cutting space of a cutting knife of the winding machine.

[0019] Beneficial effect: if there is no movable roller parallel to the glue receiving roller, after the adhesive tape is wound, the adhesive tape is in an inclined state after crossing the object to be wound and the glue receiving roller. At this time, when the cutting knife cuts, on the one hand, the inclined adhesive tape increases the difficulty of cutting or requires special movement path of the cutting knife to easily cut the adhesive tape; on the other hand, if the tail end of the adhesive tape is also fixed on a stationary part, the tail end of the adhesive tape will also be hard to separate, which will cause the risk of adhesive tape shrinkage and adhesion. However, the addition of the movable roller of the present scheme makes the adhesive tape in the cutting space flat, which facilitates easy cutting of the cutting knife, and the setting of the movable roller makes the adhesive tape tail end receive less hard separation force when it is pressed, thereby greatly reducing or even avoiding the problem of adhesive tape self-sticking due to stretching to relaxation.

[0020] Preferably, each of the glue sticking assemblies comprises a swing lever, a glue sticking arm and a glue sticking wheel, the swing lever is rotationally connected to the frame, the cantilever section of the swing lever is rotationally connected to the glue sticking arm, the cantilever section of the glue sticking arm is rotationally connected to the glue sticking wheel, the glue sticking wheel is used for sticking the adhesive tape on the winding object, the glue sticking arm is connected with the swing lever through a glue sticking elastic element, and the glue sticking elastic element makes the glue sticking arm keep a set angle with the swing lever in a free state.

[0021] Beneficial effects: when the glue sticking arm is close to the winding object under the drive of the swing lever, the glue sticking wheel gradually contacts the adhesive tape. Then, the swing lever is continuously rotated to make the glue sticking arm closer to the winding object, and the glue sticking wheel presses the adhesive tape to the surface of the winding object. Due to the existence of the glue sticking elastic element, the glue sticking wheel can adapt to the shape of the surface of the winding object (such as flat, curved or concave), so as to realize the flat sticking of the adhesive tape.

[0022] In the process of sticking the adhesive tape, as the glue sticking arm is close to the winding object under the drive of the swing lever, the extrusion force of the glue sticking wheel on the adhesive tape which has not been pulled off will gradually increase, and the increased extrusion force can make the end of the adhesive tape be pulled off and gradually completely pressed to the surface of the winding object under the action of the glue sticking wheel with the swing lever. This process not only realizes the automatic increase of the extrusion force, but also uses the increased extrusion force to make the adhesive tape tightly adhere to the surface. In addition, since the contact between the glue sticking wheel and the winding object is always affected by the glue sticking elastic element, the angle of the glue sticking arm can be adaptively adjusted, and in combination with the rolling setting of the glue sticking wheel, it is ensured that the glue sticking assembly is not easy to be damaged, compared with the existing adhesive tape sticking structure with a brush, the structure of the present scheme is simpler, more reliable, has a longer service life and the like.

[0023] Preferably, the glue sticking wheel is a glue sticking roller, so as to reduce the friction in the process of pressing the adhesive tape, improve the quality after the adhesive tape is pressed and help to prolong the service life of the glue sticking assembly.

[0025] Preferably, the swing lever is a bent swing lever / arc swing lever, and the bent / arc structure of the swing lever is used to avoid the glue receiving structure of the winding machine. The glue sticking wheel is used to make the stroke of the glue sticking wheel exceed the projection position of the cutting knife on the winding object after the swing lever swings, so as to completely flatten and press the adhesive tape which is originally obliquely pulled on the winding object and the glue receiving assembly to the position exceeding the projection position of the cutting knife on the winding object.

[0026] Preferably, the cutting assembly further comprises a cutting knife, an energy storage elastic member and a limiting member, the cutting knife is rotationally connected to the frame, the energy storage elastic member is connected between the cutting knife and the frame, the energy storage elastic member is used to give the cutting knife a force to approach the wound object, the cutting knife is driven to move away from the wound object when the glue receiving arm moves away from the wound object, and the limiting member is used to limit the rotation of the cutting knife after the energy storage elastic member completes energy storage.

[0028] Preferably, the cutting assembly further comprises a driving wheel and a cutting arm, the driving wheel is rotationally connected to the frame, the driving wheel is fixed with a driving rod, the glue receiving arm pushes the driving rod to rotate during the process of moving away from the wound object, the cutting arm is rotationally connected to the frame, the cutting knife is detachably connected to the cutting arm, the cutting arm is coaxially fixed with a driven wheel, the driving wheel and the driven wheel are in transmission connection, and the energy storage elastic member is installed between the cutting arm and the frame.

In addition, the detachable connection of the cutting knife on the cutting arm also helps to reduce the use cost and facilitate maintenance.

[0030] Preferably, the cutting arm is further fixed with a brush / elastic plate, the brush / elastic plate is used to abut against the glue receiving roller to press the adhesive tape, so as to ensure that the adhesive tape is easily cut off and can be stably pasted on the glue receiving roller.

[0083] I. Adhesive assembly 100

[0084] In combination Figures 7 to 9 ​The adhesive assembly 100 comprises a swing lever 11, an adhesive arm 12 and an adhesive roller 13.

The two limiting portions and the two pushing portions are located on the same side of the two torsion arms of the adhesive elastic element 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 the 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 surface is fixed on the adhesive arm 12, so as to facilitate the installation of the adhesive elastic element 14, the limiting portion and the pushing ring 121, and to meet the clockwise or counterclockwise rotation requirement of the adhesive arm 12 after being subjected to an external force.

[0086] When the adhesive arm 12 approaches the winding object under the drive of the swing lever 11, the adhesive roller 13 gradually contacts the adhesive tape through the adhesive assembly 100. Then, the swing lever 11 is continuously rotated to make the adhesive arm 12 closer to the winding object, and the adhesive roller 13 presses the adhesive tape to the surface of the winding object. Due to the existence of the adhesive elastic element 14, the adhesive 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 adhesion of the adhesive tape. In addition, the adhesive roller 13 presses the adhesive tape twice, i.e. once when the adhesive arm 12 approaches the winding object and drives the adhesive roller 13 to complete the pressing of the adhesive tape, and again when the adhesive arm 12 retreats and restores to make the adhesive roller 13 press the adhesive tape, so that the head of the adhesive tape can be tightly adhered after winding.

[0087] During the tape application process, as the lever 11 moves the tape application arm 12 closer to the object being wrapped, the pressure exerted by the tape application roller 13 on the remaining tape gradually increases. This increased pressure allows the tape end to detach under pressure, and the tape end is gradually and completely pressed onto the surface of the object being wrapped as the tape application roller 13 moves with the lever 11. This process not only achieves automatic increase in pressure but also utilizes this increased pressure to ensure the tape adheres tightly to the surface. Furthermore, since the contact between the tape application roller 13 and the object being wrapped is always influenced by the tape application elastic element 14, the angle of the tape application arm 12 can be adaptively adjusted.

[0088] In one embodiment, to ensure that the end of the tape can extend beyond the cutting projection position of the cutter 33 after being pressed by the applicator roller 13, in combination with Figure 10 and Figure 11 The swing arm 11 is a bent swing arm 11 / arc swing arm 11. The bent / arc structure of the swing arm 11 is used for the adhesive receiving assembly 200 of the wrapping machine to avoid air leakage. The adhesive roller 13 is used to position the adhesive receiving assembly 200 and the wrapped object after the swing arm 11 swings. The travel of the adhesive roller 13 exceeds the projection position of the cutter on the wrapped object, so that the tape that was originally stretched diagonally on the wrapped object and the adhesive receiving assembly 200 is completely flattened on the wrapped object and the pressing length exceeds the projection position of the cutter 33 on the wrapped object. With the symmetrical arrangement of the head adhesive assembly 100 and the tail adhesive assembly 100, the tape is finally overlapped on the wrapped object, ensuring the wrapping strength of the tape for one turn.

[0089] In summary, the adhesive application component 100 of this embodiment is not only simple in structure and highly reliable, but also highly adaptable and durable. It can also easily achieve overlapping of the beginning and end segments of the adhesive tape, thereby improving the wrapping strength.

[0090] II. Adhesive bonding assembly 200

[0091] Combination Figures 12 to 16 The adhesive splicing assembly 200 includes an adhesive splicing drive, an adhesive splicing arm 21, adhesive splicing rollers 22, movable rollers 23, and a stop 24. The adhesive splicing arm 21 is slidably connected to the frame 10. The adhesive splicing rollers 22 and 23 are mounted on the adhesive splicing arm 21, and both the adhesive splicing rollers 22 and 23 can rotate freely around their own centers. The adhesive splicing drive drives the adhesive splicing arm 21 to move axially along the adhesive splicing rollers 22. Under the drive of the adhesive splicing drive, the adhesive splicing arm 21 slides along the frame 10 to move away from or towards the object being wrapped. After the adhesive splicing arm 21 approaches the object being wrapped, the adhesive splicing rollers 22 and 23 are located within the enclosed area of ​​the circumferential movement of the adhesive roll on the wrapping machine. The adhesive splicing drive can be a reciprocating linear module, a linear drive structure, a linear electric cylinder, a linear pneumatic cylinder, or other pneumatic / electric drive structure that drives the adhesive splicing arm 21 to move linearly.

[0092] 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 be free from the constraint of the stopper 24). The stopper 24 is implemented in a braking mode for the glue receiving roller 22. In one embodiment, the glue receiving roller 22 is fixed with a stopper 221, and the stopper 221 can abut against or concave-convex match with the stopper 24. In the drawings, the stopper 24 is a reed, and the stopper 221 is a polygonal abutting sleeve fixed on the glue receiving roller 22. The abutting sleeve is used to abut against the reed after the glue receiving arm 21 is close to the object to be wound to a certain position, so as to limit the free rotation of the glue receiving roller 22.

[0093] The movable roller 23 is parallel to the glue receiving roller 22, and a cutting space for the cutting knife 33 of the winding machine is reserved between the movable roller 23 and the glue receiving roller 22.

[0094] When the winding machine starts to wind, the end of the adhesive tape is pasted on the glue receiving roller 22 stopped by the stopper 221. With the circumferential movement of the adhesive tape, the adhesive tape is pulled out. The glue receiving roller 22 which cannot rotate in the process can ensure that the end of the adhesive tape is fixed on the glue receiving roller 22 and does not fall off. When the winding is completed, the adhesive tape is across the glue receiving roller 22 and the movable roller 23. The glue receiving roller 22 which is limited in rotation by the stopper 24 can make the adhesive tape fixed on it and not loose with the cutting of the cutting knife, so as to prepare for the next winding.

[0095] 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 and smoothed, the end of the adhesive tape can easily rotate and fall off from the glue receiving roller 22.

[0096] Therefore, the embodiment realizes 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.

[0097] In addition, the movable roller 23 which is parallel to the glue receiving roller 22 is provided, so that when the adhesive tape needs to be cut, the adhesive tape is pasted between the glue receiving roller 22 and the movable roller 23. The cutting knife 33 of the winding machine is inserted between the two rollers to quickly and easily cut the adhesive tape. The end of the cut adhesive tape is pasted on the glue receiving roller 22, and the tail end of the cut adhesive tape is pasted on the movable roller 23, which facilitates the pressing and smoothing of the tail end of the adhesive tape wound on the object to be wound. Because the tail end of the adhesive tape is pasted on the movable roller 23 which can rotate freely, the tail end of the adhesive tape can also easily fall off during the pressing and smoothing process, so as to ensure that the tail end of the adhesive tape can be smoothly pasted on the object to be wound.

[0098] III. Cutting assembly 300

[0099] In combination Figures 12 to 16 The cutting assembly 300 comprises 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. The driving rod 311 is rotated by the pushing of the glue receiving arm 21 during the unwinding of the winding object. The cutting arm 32 is rotationally connected to the frame 10. 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 cantilever section of the cutting arm 32 is provided with the cutting knife 33. 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 at 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 winding object. The energy storage elastic member 34 is used to store energy after the frame 10 is away from the winding object. In the embodiment, the limiting member 35 is used to limit the rotation of the driving wheel 31 after the energy storage elastic member 34 completes the energy storage. In the 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 mode can be the same. Therefore, the embodiment will not be described in detail for the limiting scheme of the driven wheel.

[0100] Specifically, the limiting member 35 is rotationally connected to the frame 10. 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 the limiting member 35 with a force towards the driving wheel 31. In the embodiment, the pushing elastic member 36 is a spring.

[0101] 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 13 One of the limiting member 35 and the driving wheel 31 is provided with a limiting structure, and the other is provided with a matching structure. The limiting structure and the matching structure can be in abutment or can be concave-convex matched. In the drawings of the embodiment, the limiting member 35 is provided with a limiting hook, and the driving wheel 31 is machined with a convex matching surface. The limiting hook and the abutment surface can be in abutment / hooked. When the two are in abutment, the driving wheel 31 is limited. Of course, the limiting structure and the matching structure can also be a concave-convex matching structure, which realizes the limitation through concave-convex matching. When the driving wheel 31 needs to be limited by the limiting member 35, the limitation of the driving wheel 31 by the limiting member 35 can be removed.

[0102] In order to reduce the contact wear between the glue receiving 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. The glue receiving arm 21 is provided with a wedge surface 211 abutting against the driving wheel. The glue receiving arm 21 is retracted by pushing the driving wheel to roll through the wedge surface 211. The driving wheel drives the driving rod 311 to swing, and the driving wheel 31 rotates.

[0103] In order to make the adhesive tape cut, the adhesive tape is tightly attached to the adhesive roller 22 and the movable roller 23, and two brushes 37 / elastic plates are also fixed on the cutting arm 32, which are used to press the adhesive tape against the adhesive roller 22, and the elastic plates have 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.

[0104] In one embodiment, in order to improve the degree of automation, a trigger is connected between the tail adhesive assembly 100 and the cutting assembly 300, the trigger includes a pull cable 101, one end of the pull cable 101 is connected to the cantilever end of the limiting part 35, and the other end of the pull 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 by a certain angle, which pulls the pull cable 101, so that the limiting part 35 overcomes the elastic force of the pushing elastic part 36, and the elastic potential energy of the cutting assembly 300 is released, and the cutting knife 33 is close to the wound object and then cuts the adhesive tape. The specific embodiment can be as follows:

[0105] The first mode is combined with Figures 17 to 20 , the trigger further includes 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 trigger lever 105, one end of the connecting rod 102 is rotationally connected to the eccentric position of the trigger driving wheel 103, and the other end of the connecting rod 102 is rotationally connected to the eccentric position of the swing rod 11. The connecting rod 102 is connected to the two ends of the swing rod 11 through the adhesive arm 12, so that when either of the swing rod 11 or the trigger driving wheel 103 is rotated by the adhesive driving machine, the swing rod 11 and the trigger driving wheel 103 can be rotated through the connecting rod 102. In this embodiment, the adhesive driving machine can be a driving motor that drives the swing rod 11 to rotate or the trigger driving wheel 103 to rotate, when the adhesive driving machine is a driving motor that drives the trigger driving wheel 103 to rotate, the swing rod 11 can have a larger torque through the structure 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 reducer. Of course, the adhesive driving machine can also be a cylinder that drives the swing rod 11 to rotate or the trigger driving wheel 103 to rotate, for example, a cylinder is used as the driving source of the adhesive driving machine, and the cylinder body is rotationally connected to the rack 10. This cylinder driving mode is a prior art, and this embodiment is only briefly described, for example, the piston rod end of the cylinder is rotationally connected to the eccentric position of the swing rod 11 / the eccentric position of the trigger driving wheel 103.

[0106] In this way, one end of the cable 101 is connected to the limiting member 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 cable 101 can drive the trigger roller 104 to push the trigger lever 105 after the trigger drive wheel 103 rotates, thereby pulling the cable 101 to pull the limiting member 35 away from the driving wheel 31. As the limiting member 35 overcomes the elastic force of the pushing elastic member 36, the elastic potential energy of the cutting assembly 300 is released.

[0107] In addition, in this way, in order to make the cable 101 pull more smoothly and the installation structure more compact, a fixed pulley is installed on the rack 10, so that after the one end of the cable 101 is connected to the limiting member 35, it needs to pass through the fixed pulley and then be connected to the trigger lever 105.

[0108] The second way is to combine Figures 21 to 23 The cable 101 is connected to the cantilever end of the limiting member 35 by passing through the fixed pulley, and the other end is installed on the rack 10. When the lever 11 drives the rubberized arm 12 to approach the wrapped object, the swinging lever 11 drives the cable 101 to be pulled, thereby driving the limiting member 35 to overcome the elastic force of the pushing elastic member 36, and then releasing the rotation limitation of the driving wheel 31, achieving the purpose of active cutting of the cutter 33 under the elastic potential energy.

[0109] In this embodiment, after the adhesive tape end is pasted, the glue connecting driving machine of the glue connecting assembly 200 drives the glue connecting arm 21 to retreat and move away from the winding position of the wrapped object. The retreat and movement away of the glue connecting arm 21 pushes the driving wheel and the driving rod 311 to rotate through the wedge surface 211 carried by the glue connecting arm 21, thereby driving the cutter 33 to move away from the wrapped object through the driving wheel 31- driven wheel- cutting arm 32, and the energy storage elastic member 34 realizes energy storage for the next cutting of the cutting assembly 300 (reaches Figure 16 The state shown).

[0110] When the adhesive tape is pasted to the glue connecting roller 22 and the movable roller 23 of the glue connecting assembly 200 again, the action of the tail pasting glue connecting assembly 100 triggers the release of the elastic potential energy of the cutter 33 of the cutting assembly 300, thereby completing the automatic cutting of the adhesive tape.

[0111] The whole adhesive tape pasting device realizes automatic energy storage of the cutting assembly 300 after the glue connecting assembly 200 retreats, and energy release of the cutting assembly 300 after the start of the tail pasting glue connecting assembly 100, which makes the whole control process more simple and convenient, and saves the driving machine cost for the cutting assembly 300.

[0112] The embodiment also provides a use method of the adhesive tape pasting device, which comprises the following steps:

[0113] When the adhesive tape starts to be wound, the adhesive roller 22 is controlled to extend below the object to be wound and is braked by the stopper 221, so as to ensure that the end of the adhesive tape can be fixed on the adhesive roller 22, thereby facilitating fast winding; after the adhesive tape has started to be pasted on the object to be wound, the adhesive roller 22 is controlled to move out of the limitation of the stopper 24, and the adhesive roller 13 of the pasting assembly 100 is continuously controlled to move, so as to pull the end of the adhesive tape off the adhesive roller 22 and gradually press and paste the end of the adhesive tape to the bottom of the object to be wound; in this process, since the stopper 24 releases the self-rotation limitation of the adhesive roller 22, the adhesive roller 22 can automatically rotate under the pressing and pasting of the pasting assembly 100, thereby facilitating the end of the adhesive tape to fall off.

[0114] Embodiment Two

[0115] In combination with Figure 1 , Figures 24 to 27 , the embodiment provides a winding machine, which comprises the adhesive tape pasting device of the embodiment one, further comprises a winding mechanism 400 for driving the adhesive tape to move circumferentially, and a goods platform 500 for placing the object to be wound.

[0116] In combination with Figures 24 to 27 , the winding mechanism 400 comprises a front mounting plate 401, a rear mounting plate 402, a winding drive machine 41, a rotating wheel 42, at least two supporting wheels 43, at least two sets of pressing wheels 44, and an adhesive tape mounting rack 45 mounted on the rotating wheel 42. The winding drive machine 41 is fixedly mounted on the machine frame 10, the front mounting plate 401 and the rear mounting plate 402 are fixedly mounted on the machine frame 10, the front mounting plate 401 and the rear mounting plate 402 are fixedly connected through a plurality of connecting columns / connecting blocks 403 to form a cage type frame, all the supporting wheels 43 and the sets of pressing wheels 44 are located between the front mounting plate 401 and the rear mounting plate 402, and the supporting wheels 43 are rotationally connected to the front and rear mounting plates.

[0117] The number of the supporting wheels 43 in the embodiment is four, each of the supporting wheels 43 is rotationally connected to the machine frame 10, and the winding drive machine 41 drives the rotating wheel 42 to rotate through a belt transmission mode; the number of the sets of pressing wheels 44 in the embodiment is three, each of the sets of pressing wheels 44 comprises a pressing arm 441, a pressing roller 442, and a first elastic member 443, the pressing roller 442 is rotationally connected to the pressing arm 441, the first elastic member 443 is connected between the pressing arm 441 and the machine frame 10, the first elastic member 443 is used to press the pressing roller 442 towards the rotating wheel 42, the pressing roller 442 is located above the supporting wheel 43 and is located with the supporting wheel 43 outside the periphery of the rotating wheel 42, the rotating wheel 42 is supported by the supporting wheel 43 and rotates in the enclosed area of the supporting wheel 43 and the pressing roller 442; the rotating wheel 42 and the supporting wheel 43 are in concave-convex cooperation at the contact part, and the rotating wheel 42 and the pressing roller 142 are also in concave-convex cooperation at the contact part (for example, the rotating wheel 42 is concave and the pressing roller 442 is convex, or the rotating wheel 42 is convex and the pressing roller 442 is concave). Figure 25As shown in the figure, in this embodiment, the outer periphery of the rotating wheel 42 is provided with a groove, and the supporting wheel 43 and the pressing roller 142 are both sunk into the groove 421 of the rotating wheel 42; in this embodiment, the first elastic member 443 is a spring.

[0118] In combination Figures 24 to 26 In one of the schemes of the pressing wheel set 44, the pressing arm 441 is located between the front mounting plate 401 and the rear mounting plate 402 and is rotationally connected to the front and rear mounting plates, one end of the first elastic member 443 is connected to the rack 10, the other end is connected to the cantilever end of the pressing arm 441, and the pressing roller 442 is rotationally connected to the cantilever middle section of the pressing arm 441.

[0119] The pressing wheel set 44 of this embodiment is simple in structure and can meet the requirements of the floating pressing force on the rotating wheel 42. Under this floating pressing, even if the speed of the rubber belt being pulled out is inconsistent during the winding process, causing the rotating wheel 42 to be unevenly stressed and the pressure on each pressing roller 442 / supporting wheel 43 to be inconsistent, the rotating wheel 42 can still be ensured to be in contact with the multiple pressing rollers 442 and supporting wheels 43 under the elastic force of the first elastic member 443, thereby ensuring the stable rotation of the rotating wheel 42, greatly reducing or even avoiding the situation of abnormal noise caused by the rotating wheel 42 impacting the pressing roller 442 / supporting wheel 43 due to uneven circumferential stress on the rotating wheel 42 during the winding process of the rubber belt, and reducing the noise of the winding mechanism during winding. In addition, the contact between the pressing wheel set 44 and the rotating wheel 42 can be adaptively adjusted, thereby reducing or even avoiding noise and lowering the machining precision requirements of the rotating wheel 42.

[0120] In addition, the provision of the front mounting plate 401 and the rear mounting plate 402 in this embodiment ensures that the stress on the rotating wheel 42 is transmitted to the front and rear mounting plates through the supporting wheel 43 and the pressing wheel set 44, thereby ensuring the stability and uniformity of the stress on the rotating wheel 42 during rotation. In addition, the front and rear mounting plates can be made of thin plates to reduce the machining and manufacturing costs.

[0121] In combination Figure 25 And Figure 26 The rack 10 is also provided with a first tensioning wheel set 46 for controlling the tensioning force of the transmission belt, which includes a first tensioning arm 461, a first tensioning roller 462, and a second elastic member 463. A tensioning bolt 464 is threadedly connected to the rack 10. The first tensioning roller 462 is rotationally connected to the first tensioning arm 461. The second elastic member 463 is arranged between the tensioning bolt 464 and the first tensioning arm 461. The first tensioning arm 461 is slidingly connected to the rack 10, and the sliding direction of the first tensioning arm 461 is the axial direction of the tensioning bolt 464. The first tensioning roller 462 is used to contact the belt, and the second elastic member 463 causes the first tensioning roller 462 to press against the belt. In this embodiment, the second elastic member 463 is a spring.

[0122] The output wheel of the winding driving machine 41 is sleeved with a belt, the belt directly drives the rotating wheel 42 to rotate, and the belt is clamped between the supporting wheel 43 / pressing roller 442 and the surface of the rotating wheel 42. After the winding driving machine 41 is started, the rotating wheel 42 is directly driven to rotate by the belt, and the supporting wheel 43 and the pressing roller 442 are rolled and limit the rotating wheel 42 from the upper and lower positions during the rotation.

[0123] In the embodiment, the first tensioning wheel set 46 with the first tensioning roller 462 and the second elastic member 463 is used to adjust the tensioning force of the belt transmission of the winding driving machine 41, so as to ensure the stability and reliability of the belt transmission. The elastic force of the second elastic member 463 on the first tensioning arm 461 can be adjusted by screwing the tensioning bolt 464, so as to further expand the tensioning range of the first tensioning wheel set 46 and improve the applicability.

[0124] II. Adhesive tape mounting frame 45

[0125] Combined Figure 27 The adhesive tape mounting frame 45 is fixed on the rotating wheel 42 and moves circumferentially around the center of the rotating wheel 42 with the rotation of the rotating wheel 42. The adhesive tape mounting frame 45 is provided with a tensioning core for tensioning the film. The adhesive tape mounting frame 45 is provided with a second tensioning wheel set 47 and a silencer wheel set 48. The adhesive tape on the film passes through the silencer wheel set 48, then passes through the guide roller on the adhesive tape mounting frame 45, and then passes through the second tensioning wheel set 47 for winding.

[0126] The second tensioning wheel set 47 includes a second tensioning arm 471, a second tensioning roller 472, and a third elastic member 473. The second tensioning roller 472 is rotationally connected to the second tensioning arm 471. The third elastic member 473 is connected between the second tensioning arm 471 and the adhesive tape mounting frame 45. The second tensioning roller 472 is used to contact the pulled-out adhesive tape. The third elastic member 473 makes the second tensioning roller 472 resist the adhesive tape. In the embodiment, the third elastic member 473 is a spring. The third elastic member 473 is used to adjust the tensioning force after the adhesive tape is pulled out, so as to ensure that the adhesive tape always maintains a straight state during the winding process.

[0127] The second tensioning arm 471 is rotationally connected to the adhesive tape mounting frame 45. The second tensioning roller 472 is rotationally connected to the cantilever section of the second tensioning arm 471. One end of the third elastic member 473 is connected to the adhesive tape mounting frame 45, and the other end is connected to the cantilever section of the second tensioning arm 471. The third elastic member 473 enables the second tensioning arm 471 to swing.

[0128] The sound-eliminating wheel set 48 comprises a sound-eliminating arm 481, a sound-eliminating roller 482 and a fourth elastic member 483. The sound-eliminating roller 482 is rotatably connected to the sound-eliminating arm 481. The fourth elastic member 483 is connected between the sound-eliminating arm 481 and the adhesive tape mounting rack 45. The sound-eliminating roller 482 is used to contact the pulled-out adhesive tape. The fourth elastic member 483 enables the sound-eliminating roller 482 to give the adhesive tape a force away from the film.

[0129] The sound-eliminating arm 481 is rotatably connected to the adhesive tape mounting rack 45. The sound-eliminating roller 482 is rotatably connected to a cantilever section of the sound-eliminating arm 481. One end of the fourth elastic member 483 is connected to the adhesive tape mounting rack 45. The other end of the fourth elastic member 483 is connected to the cantilever section of the sound-eliminating arm 481. The fourth elastic member 483 enables the sound-eliminating arm 481 to swing. The sound-eliminating roller 482 is away from / near to the film by swinging. In the embodiment, the fourth elastic member 483 is a spring.

[0130] The presence of the sound-eliminating wheel set 48 with the fourth elastic member 483 and the sound-eliminating roller 482 enables the adhesive tape to always have a force given by the fourth elastic member 483 to pull the adhesive tape away from the film when the adhesive tape is pulled out of the film. When the pulling-out speed is too low, the sound-eliminating wheel set 48 cooperates with the second tensioning wheel set 47 to slow down the pulling-out speed of the adhesive tape while keeping the adhesive tape straight. When the pulling-out speed needs to be increased, the tensioning force of the adhesive tape is automatically adjusted by the second tensioning wheel set 47 and the sound-eliminating wheel set 48 to ensure that the adhesive tape is not too tight and does not produce a sharp and irritating sound due to instantaneous rapid pulling-out, thereby reducing the abnormal sound during the winding process.

[0131] The embodiment also provides a winding method as follows:

[0132] Step 1: Place the object to be wound 600 on the goods platform 500.

[0133] Step 2: Start the winding mechanism 400. The winding mechanism 400 drives the film on the adhesive tape mounting rack 45 to move in the circumferential direction. The adhesive tape rotates along the object to be wound 600 to paste the adhesive tape. During the process, the head end of the adhesive tape is pasted on the adhesive tape receiving roller 22 of the adhesive tape receiving assembly 200.

[0134] Step 3: The adhesive tape mounting rack 45 ascends to press the adhesive tape to the surface of the object to be wound 600.

[0135] Step 4: When the end of the adhesive tape starts to press the adhesive tape to the object to be wound 600 (in the embodiment, the object to be wound 600 is a carton, and the pressing position is the bottom edge of the carton), the adhesive tape receiving arm 21 drives the adhesive tape receiving roller 22 to retreat to disengage the stopper 24.

[0136] Step 5, the glue roller 13 of the head-tape-gluing assembly 100 moves to completely press the tape onto the object 600 (the travel of the glue roller 13 exceeds the projected position of the cutter 33 on the object, so as to completely flatten and press the originally obliquely pulled head end of the tape beyond the projected position of the cutter 33 on the object).

[0137] Step 6, the glue roller and the glue arm 21 of the head-tape-gluing assembly 100 are controlled to move to a region that does not affect the circumferential movement of the tape mounting rack 45, and the retreat movement of the glue arm 21 is synchronous with the energy storage of the cutter 33.

[0138] During the retreat movement of the glue arm 21, the wedge surface 211 pushes the driving rod 311 to rotate, so that the power is transmitted to the driven wheel through the driving wheel 31, the rotation of the cutting arm 32 is realized, and the subsequent cutting of the cutter 33 is energized by the energized elastic member 34.

[0139] Step 7, the tape is wound on the object 600 for one or more turns under the driving of the winding mechanism 400.

[0140] Step 8, when the winding turns are reached, the glue roller 22 of the glue assembly 200 is controlled to extend, and the tape passes from the side of the glue roller 22 away from the object 600 (in this embodiment, below the glue roller 22), so that the tape is adhered to the glue roller 22, and the tape is controlled to stop winding.

[0141] Step 9, the tail-tape-gluing assembly 100 moves, and the glue roller of the tail-tape-gluing assembly 100 approaches the object 600 to press the tape onto the object 600.

[0142] In this process, the action of the tail-tape-gluing assembly 100 will trigger the release of the elastic potential energy of the cutting assembly 300 to cut the tape between the glue roller 22 and the movable roller 23.

[0143] Specifically, after the swing rod of the tail-tape-gluing assembly rotates by a certain angle, the cable is pulled, the limiting member is pulled away from the driving wheel by overcoming the elastic force of the pushing elastic member, the driving is lost, the elastic potential energy of the cutting assembly is released, and the cutter cuts the tape.

[0144] Step 10, the tail-tape-gluing assembly 100 continues to move to completely press the tail of the tape onto the object 600, the travel of the glue roller 13 exceeds the projected position of the cutter 33 on the object, so as to completely flatten and press the originally obliquely pulled tail end of the tape beyond the projected position of the cutter 33 on the object, and the head and tail of the tape are overlapped.

[0145] Step 11, the tail-tape-gluing assembly 100 returns to the initial position, and the winding is completed. After a new object 600 is automatically or manually put in, the automatic winding steps of steps 1 to 10 can be performed.

It should be pointed out that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, which will not affect the effect and practicality of the patent.
