Description

TECHNICAL FIELD

[0001] The utility model relates to winding packaging technical field, concretely relates to a kind of glue jointing assembly, cut device and winding machine. BACKGROUND

[0002] In the packaging technical field, it is extremely important to wrap objects with adhesive tape. Non-entire-circle winding of adhesive tape can achieve sealing of the wrapped objects (such as paper boxes, turnover boxes, and objects with certain shapes), while entire-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 objects during transportation and storage, preventing the objects from scattering 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 glue jointing function and automatic pressing and pasting function of the head and tail ends of the adhesive tape. Specifically, when starting to wind, the end of the adhesive tape is pasted on the glue jointing 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 as the adhesive tape roll moves. The end of the adhesive tape pasted on the glue jointing 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 glue jointing 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 a 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, affecting the stability of the mechanism.

[0005] On the other hand, the existing technology also has the risk of adhesion caused by adhesive tape retraction. After hard pulling off, the adhesive tape suddenly relaxes from a straightened state, which easily leads to self-adhesion of the end due to elastic retraction.

[0006] For example, patent announcement No. CN218506200U "Adhesive tape winding device" uses a glue limiting plate to joint glue, and for example, patent announcement No. CN217295123U "Smoothing mechanism of winding packaging machine" uses a glue jointing rod fixed on a swing arm to joint glue.

[0007] In view of the problems existing in the glue connection, the prior art has another way, for example, the patent with the patent number CN118811209A《Automatic tape sealing and packaging machine》 applied and disclosed in 2024 discloses that the clamping or loosening of the 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 tape through a plane, and when the 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 still needs to be pulled hard to pull the tape down, so it cannot solve the problem mentioned above. The patent with the patent number CN112441293A《Rotary ring surrounding type tape sealing and packaging machine》 of the same inventor as the above patent is provided with a tape push plate to solve the problem of difficult degumming, but the tape push plate is connected with a spring, and the tape push plate is also provided with a convex rib and a convex and concave tooth, the rotation of the lever drives the convex and concave tooth on the tape push plate to push the tape downward to reduce the difficulty of degumming, but this way also has the problem of complex structure. Practical new type content

[0008] The utility model intends to provide a glue connection assembly to realize the effect that the tape end can be tightly adhered to the glue connection structure at the initial stage of winding and easily detached from the glue connection structure during degumming.

[0009] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0010] A glue connection assembly, comprising a glue connection arm and a glue connection wheel mounted on the glue connection arm, the glue connection arm is used for moving away from or approaching the object to be wound, the glue connection wheel is a glue connection roller capable of self-rotation, and further comprising a stopper for limiting the self-rotation of the glue connection roller.

[0011] The principle and advantages of the present scheme are as follows: when the tape on the winding machine starts to adhere to the object to be wound, in order to ensure that the tape end is fixed on the glue connection roller, the stopper is used to limit the self-rotation of the glue connection wheel approaching the object to be wound, that is, the glue connection roller cannot rotate, ensuring that the tape end is tightly adhered to the glue connection roller, thereby achieving the required pulling force when the tape is pulled out; when the tape is adhered to the object to be wound and the end of the tape is also adhered to the object to be wound, the glue connection arm is controlled to act, so that the glue connection roller can be separated from the stopper to brake the glue connection roller, so that the glue connection roller can rotate freely. When the glue connection arm drives the glue connection roller to move away from the object to be wound, the glue connection roller will automatically rotate and easily detach the tape end from the glue connection roller, solving the problem that in the prior art, the tape end needs to be fixed to facilitate winding during glue connection, and the tape needs to be easily detached from the glue connection structure during degumming, which cannot be considered in both cases.

[0012] 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, and can fix the end of the adhesive tape when necessary, or allow the glue receiving roller to rotate when the end of the adhesive tape needs to be released, so as to facilitate the release of the adhesive tape under small extrusion force, and help to improve the mechanism working stability of the glue receiving assembly and the adhesive structure.

[0013] Preferably, the glue receiving roller is fixed with a stopper, and the stopper can abut against or concave-convex cooperate with the stopper.

[0014] Alternatively, the glue receiving roller is provided with a ferromagnet, and the stopper is a magnet / electromagnet, and the stopper limits the rotation of the glue receiving roller by magnetic attraction when the stopper is close to or abuts against the glue receiving roller.

[0015] 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 for abutting against the reed.

[0016] Preferably, the glue receiving arm is provided with a movable roller parallel to the glue receiving roller, and the movable roller and the glue receiving roller reserve a cutting space for a cutting knife of a winding machine.

[0017] Beneficial effects: If there is no movable roller parallel to the glue receiving roller, the adhesive tape is in an inclined state after being wound, and 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 detach, which will cause the risk of adhesive tape retraction and adhesion. However, the addition of the movable roller of the present scheme can make the adhesive tape in the cutting space flat, facilitate the easy cutting of the cutting knife, and the setting of the movable roller can reduce the hard detachment force of the tail end of the adhesive tape when it is pressed and pasted, thereby greatly reducing or even avoiding the problem of adhesive tape self-adhesion caused by stretching to relaxation.

[0018] Preferably, the stopper is fixedly installed.

[0020] Beneficial effects: the interface cutting device of the scheme utilizes the back-off action of the interface glue arm, the interface glue assembly itself is used as the driving structure of the cutting assembly, the cutting knife is moved away from the winding object through movement, so that the energy storage elastic member completes energy storage, and the rotation of the cutting knife is limited by the limiting member after energy storage is completed, so that the elastic potential energy of the cutting knife is not released by the action of the interface glue arm approaching the winding object, so that the elastic potential energy is only released when the cutting assembly needs to cut the adhesive tape, so as to achieve the purpose of cutting the adhesive tape by the cutting knife.

[0021] Preferably, the cutting assembly further comprises a driving wheel and a cutting arm, the driving wheel is rotatably connected to the rack, the driving rod is fixed on the driving wheel, the driving rod is rotated by the interface glue arm during the process of moving away from the winding object, the cutting arm is rotatably connected to the rack, 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 rack.

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

[0025] Beneficial effects: through the setting of the limiting member connected with the pushing elastic member, the rotation of the driving wheel / driven wheel is limited by the limiting member, after the rotation of the driving wheel / driven wheel is limited, the rotation of the cutting knife installed on the cutting arm is also limited, so as to achieve the purpose of limiting the release of the elastic potential energy of the cutting assembly. The structure of the limiting member is simple and convenient, when the limiting member is released, only the elastic force of the pushing elastic member needs to be overcome, so that the driving wheel / driven wheel can be released, and the rapid release of the elastic potential energy of the cutting assembly can be realized.

[0026] Preferably, the cantilever end of the driving rod is provided with a driving wheel, and the interface glue arm is provided with a wedge surface abutting against the driving wheel.

[0038] The following is further described in detail by specific embodiments:

[0039] ​​​The reference numerals in the accompanying drawings include: frame 100, adhesive receiving assembly 200, adhesive receiving arm 21, wedge surface 211, adhesive receiving roller 22, stopped part 221, movable roller 23, stopped part 24, cutting assembly 300, drive wheel 31, drive rod 311, cutting arm 32, cutter 33, energy storage elastic part 34, limiting part 35, magnet 351, pushing elastic part 36, brush 37, ferromagnetic body 312, winding mechanism 400, adhesive application mechanism 500, and cargo platform 600.

[0040] Example 1 is basically as shown in the attached document. Figures 1 to 7 As shown.

[0041] Combination Figure 1 A splicing and cutting device includes a frame 100, a splicing assembly 200 and a cutting assembly 300. The frame 100 is fixedly installed, and the splicing assembly 200 and the cutting assembly 300 are both installed on the frame 100.

[0042] 1. Glue bonding assembly 200

[0043] Combination Figure 1 , Figure 4 and Figure 5 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 100. 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. After sliding along the frame 100 under the drive of the adhesive splicing drive, the adhesive splicing arm 21 can 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 range 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.

[0044] The stop 24 is fixedly mounted on the frame 100. The stop 24 is used to restrict the free rotation of the glue-receiving roller 22 (the movable roller 23 is not constrained by the stop 24). One way the stop 24 brakes the glue-receiving roller 22 is by combining... Figures 1 to 5 The glue-receiving roller 22 is fixed with a stop 221. The stop 221 and the stop 24 can abut or engage with each other. In the attached figure, the stop 24 is a spring, and the stop 221 is a polygonal abutment sleeve fixed on the glue-receiving roller 22. The abutment sleeve is used to abut against the spring after the glue-receiving arm 21 approaches the object to be wrapped to a certain position, so as to restrict the free rotation of the glue-receiving roller 22.

[0045] The stopper 24 can also be a magnet or an electromagnet, and the adhesive roller 22 can be made of ferromagnetic material or be a ferromagnetic material itself. When the stopper 24 is close to the adhesive roller 22, the adhesive roller 22 is limited from rotating by magnetic force. Figure 6

[0046] The movable roller 23 is parallel to the adhesive roller 22, and a cutting space for the cutting knife 33 of the winding machine is reserved between the movable roller 23 and the adhesive roller 22.

[0047] When the winding machine starts winding, the end of the adhesive tape is pasted on the adhesive roller 22 stopped by the stopper 221, and the adhesive tape is pulled out as the film moves circumferentially. The adhesive roller 22 that cannot rotate in this process ensures that the end of the adhesive tape is fixed on the adhesive roller 22 and does not come off. When the winding is completed, the adhesive tape is across the adhesive roller 22 and the movable roller 23, and the adhesive roller 22 limited from rotating by the stopper 24 ensures that the adhesive tape is fixed on the adhesive roller 22 and does not come off with the cutting of the cutting knife, and prepares for the next winding.

[0048] When the end of the adhesive tape needs to be pasted on the object to be wound, the adhesive arm 21 is controlled to move, so that the stopper 24 releases the rotation limitation of the adhesive roller 22. When the end of the adhesive tape is pressed and smoothed, the end of the adhesive tape can easily come off from the adhesive roller 22 by rotating the adhesive roller 22.

[0049] Therefore, the embodiment realizes the effect that the end of the adhesive tape can be tightly pasted on the adhesive roller 22 at the initial stage of winding to facilitate the winding of the adhesive tape, and can be easily peeled off from the adhesive roller 22 when the adhesive tape is peeled off.

[0050] In addition, the movable roller 23 parallel to the adhesive roller 22 is provided, so that when the adhesive tape needs to be cut, the adhesive tape is pasted between the adhesive 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 adhesive 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. Since the tail end of the adhesive tape is pasted on the movable roller 23 that can freely rotate, the tail end of the adhesive tape can be easily peeled 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.

[0051] II. Cutting assembly 300

[0052] In combination with Figure 1 , Figure 4 and Figure 5 ​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 pushed to rotate by the glue applying arm 21 during the process of moving away from the winding object. The cutting arm 32 is rotationally connected to the rack 100. 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 rack 100. 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 rack 100 moves 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 limiting scheme for the driven wheel is not described in detail in the embodiment.

[0053] Specifically, the limiting member 35 is rotationally connected to the rack 100. The pushing elastic member 36 is further connected between the limiting member 35 and the rack 100. The pushing elastic member 36 is used to provide a force to the limiting member 35 towards the driving wheel 31. In the embodiment, the pushing elastic member 36 is a spring.

[0054] 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 with Figure 5 The 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 be in abutment or concave-convex matching. 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 / hooking. 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. The limiting is realized by concave-convex matching. When the driving wheel 31 needs to be limited by the limiting member 35, the limiting of the driving wheel 31 by the limiting member 35 can be released.

[0055] In another embodiment, in combination with Figure 7, the active wheel 31 is provided with a ferromagnetic body, the limiting piece 35 is provided with a magnet 351 / electromagnet for being attracted to the ferromagnetic body 312, after the active wheel 31 rotates to the point that the energy storage elastic piece 34 has enough elastic potential energy, the ferromagnetic body 312 is directly opposite the limiting piece 35, so that the limiting piece 35 magnetically attracts the active wheel 31 to limit the rotation of the active wheel 31. This mode can force the limiting piece 35 to swing away from the active wheel 31 by an external force to the extent that the elastic force of the pushing elastic piece 36 and the magnetic attraction force are overcome to achieve the release of the rotation limitation of the active wheel 31.

[0056] 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 by pushing the driving wheel to roll through the wedge surface 211, the driving wheel drives the driving rod 311 to swing, and the active wheel 31 rotates.

[0057] In order to make the adhesive tape adhere to the glue roller 22 and the movable roller 23 when the adhesive tape is cut, two brushes 37 / elastic plates are further 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 is provided with an elastic material that can be compressed and restored to elasticity, such as a silica gel plate, a rubber plate, etc., and only the mode of the brush 37 is shown in the embodiment.

[0058] In combination Figures 1 to 3 The use process of the cutting device is described as follows:

[0059] In combination Figure 1 After the glue arm 21 retreats away from the wound object under the driving of the glue driving machine, the wedge surface 211 on the glue arm 21 drives the driving rod 311 to swing, the rotation of the driving rod 311 drives the active wheel 31 to rotate, the active wheel 31 drives the driven wheel to rotate, and the cutting arm 32 coaxial with the driven wheel swings, the cutting arm 32 swings to move away from the wound object, and at the same time, the energy storage elastic piece 34 stores energy, after the glue arm 21 retreats, the energy storage elastic piece 34 completes energy storage, the rotation of the active wheel 31 is limited by the limiting piece 35, and the state Figure 1 is reached.

[0060] Before cutting the adhesive tape after the adhesive tape is wound, the glue arm 21 is first controlled to move close to the wound object until the glue roller 22 is conveniently pasted to the adhesive tape to be cut, and the state Figure 2 is reached. Since the limiting piece 35 still limits the rotation of the active wheel 31, the movement of the glue arm 21 does not affect the action of the cutting assembly 300.

[0061] When the adhesive tape is cut, the control limiting piece 35 releases the limitation on the driving wheel 31, the elastic potential energy of the energy storage elastic piece 34 is released, thereby driving the cutting arm 32 to rotate to approach the adhesive tape, when the cutting knife 33 rotates with the cutting arm 32, the brush 37 / elastic plate contacts the adhesive tape before the cutting knife 33, so as to press the adhesive tape on the roller, the cutting knife 33 continues to rotate with the cutting arm 32 to complete the cutting of the adhesive tape, and the state shown in Fig. 6 is reached. Figure 3

[0062] The whole process of the embodiment utilizes the retreat action of the adhesive receiving assembly 200, so as to store energy for the subsequent cutting action of the cutting assembly 300, thereby ensuring that the subsequent cutting does not need to separately provide driving for the cutting assembly 300, which is helpful to reduce the cost and save energy.
