Description

Technical Field

[0001] The utility model relates to the technical field of laser printing, and particularly relates to a peeling and winding mechanism. Background Art

[0002] Laser transfer film is a printing technology that transfers patterns through a photodecomposition process. In industrial production, multiple laser transfer films are often parallelly attached to a wide substrate, and multiple prints are carried out simultaneously. After printing, the laser transfer films are peeled off and wound, and then the wide substrate is cut into multiple narrow substrate strips according to the printing situation, that is, several printed products can be obtained at one time, improving the printing efficiency, such as the printing of cigarette inner lining paper.

[0003] During the winding process of the transfer film strip, due to reasons such as vibration and equipment errors, the phenomenon of offset may occur. The offset will cause differences in the sizes of the reels obtained from different transfer film strips, and then lead to uneven tensions of different transfer film strips, and finally cause some transfer film strips to break, affecting production. In the prior art, in order to eliminate the offset during the winding process, limiting components are usually arranged on both sides of the reel. For example, the patent document with the application number CN202223258173.2 discloses a film winding anti-offset component, which includes a winding roller and two limiting rollers arranged at both ends of the winding roller. The two limiting rollers can limit the position of the film, making the obtained reel more regular. However, the above technical solution can only be applied to the winding of a single strip of film. When multiple strips of film are wound simultaneously, the strip of film in the middle cannot be restricted, and the problem of strip film offset cannot be solved. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a peeling and winding mechanism, which can synchronously wind multiple strips of film, and can avoid excessive offset of the strip film during the winding process, thereby reducing the probability of breakage of the strip film during the winding process and ensuring the production efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A peeling and winding mechanism includes a peeling roller connected to a driving motor, a mounting frame arranged above the peeling roller, and a plurality of limiting members connected to the mounting frame and arranged along the axis direction of the peeling roller; the limiting member includes a connecting portion at the upper end, a movable extending portion in the middle, and a limiting portion at the lower end. The connecting portion is fixedly connected to the mounting frame. The movable extending portion includes a first rod body and a second rod body connected in a sliding manner, and the movable extending portion extends towards the axis direction of the peeling roller. The limiting portion includes two parallel limiting side plates and a top plate connected to the upper ends of the two limiting side plates. The limiting side plates are perpendicular to the peeling roller, and the lower ends of the limiting side plates can be lapped on the peeling roller.

[0007] The utility model limits multiple strip films wound synchronously on a stripping roller through a plurality of limiting members arranged along the axis direction of the stripping roller, reduces the size difference between the reels formed by different strip films, reduces the tension difference between different strip films, and avoids the breakage of the strip films. Specifically, the limiting part of the limiting member restricts the winding positions of the strip films from both sides through two limiting side plates, avoiding large offsets of the strip films. As the winding progresses, the diameter of the reel gradually increases, the limiting part is lifted by the reel, and the first rod body and the second rod body of the extending part slide relative to each other, enabling the limiting part to always cooperate with the edge part of the reel. In the prior art, the technical solutions of setting fixed baffles or limiting rollers to prevent the strip films from running off have certain requirements for the size of the reel and have limitations in use, while the utility model can meet different size requirements through adaptive adjustment and has a wider application range.

[0008] Further, the limiting part further includes an inner mounting shaft perpendicularly connected to the inner side surface of the limiting side plate, and an inner runner is movably connected to the inner mounting shaft.

[0009] Further, the limiting part further includes an outer mounting shaft perpendicularly connected to the outer side surface of the limiting side plate, and an outer runner is movably connected to the outer mounting shaft.

[0010] The inner runner is used for movably abutting against the circumferential surface of the reel, avoiding direct contact between the reel and the top plate, converting sliding friction into rolling friction, reducing the frictional heat during the winding process, and also avoiding the breakage of the strip film due to friction; the outer runner is used for movably abutting against the circumferential surface of the stripping roller, avoiding direct contact between the stripping roller and the lower end of the limiting side plate, reducing the frictional heat during the winding process, and avoiding noise generated by friction between the stripping roller and the limiting side plate.

[0011] Further, a notch is formed at the lower end of the limiting side plate, and the notch has an arc-shaped groove wall that is recessed upward, and the edge of the outer runner extends relative to the arc-shaped groove wall.

[0012] Further, a telescopic elastic element is provided between the connecting part and the limiting part, and the upper and lower ends of the elastic element are respectively connected to the connecting part and the limiting part.

[0013] Further, the elastic element is composed of a spring sleeved on the outer periphery of the extending part.

[0014] Further, the mounting frame has a mounting rod arranged parallel to the stripping roller, and the connecting part includes a connecting frame slidably matched with the mounting rod and a locking member for relatively fixing the connecting frame and the mounting rod.

[0015] Further, the connecting frame has a notch, both ends of the connecting frame are connected with outwardly extending ends, and the locking member is connected to the two ends.

[0016] Further, the connecting frame has a concave portion, and a mating groove corresponding to the concave portion is formed on the mounting rod.

[0017] Further, the mounting bracket further includes a supporting base member, and the end of the mounting rod is detachably connected to the supporting base member.

[0018] The application of the present utility model can achieve the following beneficial effects:

[0019] 1. By arranging a plurality of limiting members arranged along the axis direction of the peeling roller to limit a plurality of strip films wound synchronously, the present utility model reduces the size difference between the reels formed by different strip films, reduces the tension difference between different strip films, avoids the breakage of the strip films, and ensures the production efficiency.

[0020] 2. By arranging an extension portion with variable length, the present utility model enables the limiting portion to always cooperate with the edge of the reel, thereby meeting different size requirements and having a wider application range.

[0021] 3. In some embodiments, the present utility model is provided with an inner runner and an outer runner, which reduces the frictional heat during the winding process, reduces the probability of the strip film breaking, and reduces the noise generated by friction during the winding process.

[0022] 4. In some embodiments, the limiting member of the present utility model can move along the mounting rod, so as to adapt to the winding requirements at different positions. After the end of the mounting rod is disassembled from the supporting base member, the number of limiting members can also be changed to further meet different winding requirements.

Detailed Embodiments

[0026] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0027] Refer to Figure 1 And Figure 2 This embodiment provides a peeling and winding mechanism, which includes a peeling roller 1, a mounting bracket 2 and a limiting member 3;

[0028] The peeling roller 1 is horizontally installed on the frame, and one end of the peeling roller passes through the frame and is connected to the driving motor 11. Under the control of the driving motor, the peeling roller can rotate around the axis and actively wind the strip film;

[0029] The mounting bracket 2 includes a mounting rod 21 arranged parallel to the peeling roller and a support base detachably connected to the end of the mounting rod, and the support base is detachably connected to the upper end of the frame;

[0030] The limiting member 3 includes a connecting portion 31, an extending portion 32 and a limiting portion 33; the connecting portion 31 includes a connecting frame 311 with a substantially circular ring-shaped cross-section that is slidably sleeved on the outer periphery of the mounting rod 21. The connecting frame has a notch, and both ends of the connecting frame are connected with end heads 312 extending outward. The two end heads are connected by an adjustable locking member 313. The locking member can apply pressure to make the two end heads approach each other, so that the connecting frame undergoes elastic deformation and abuts against and locks with the mounting rod. The connecting frame is also provided with a concave portion 314, and the mounting rod 21 is provided with a mating groove corresponding to the position and shape of the concave portion. When the connecting frame is sleeved on the outer periphery of the mounting rod, the concave portion is embedded into the mating groove, so that the connecting frame cannot rotate around the axis of the mounting rod, ensuring that the limiting member is in the correct orientation; the extending portion 32 includes a first rod body 321 and a second rod body 322 that are slidably connected. The first rod body and the second rod body can change the overall length of the extending portion by relative sliding, so as to adapt to the size change of the reel during the winding of the strip film. The extending portion is arranged towards the axis of the peeling roller. Usually, the second rod body slides down naturally and makes the limiting portion approach the peeling roller. An elastic element 323 composed of a spring is also sleeved on the outer peripheries of the first rod body and the second rod body. The upper and lower ends of the elastic element are respectively connected to the connecting portion and the limiting portion. When the length of the extending portion is shortened, the elastic element is compressed and applies an appropriate pressure to the limiting member, making the cooperation between the limiting member and the reel more stable and improving the limiting effect; the limiting portion 33 includes two limiting side plates 331 that are parallel to each other and a top plate 332 that is vertically connected to the upper ends of the two limiting side plates. A winding cavity for accommodating the strip film is formed between the two limiting side plates. An inner mounting shaft 333 that is vertically connected to the two limiting side plates is arranged in the winding cavity. An inner runner 334 is movably mounted on the inner mounting shaft through a bearing. The inner runner is located at a position close to the upper end of the winding cavity. An outer mounting shaft 335 is vertically connected to the outside of each limiting side plate. An outer runner 336 is movably mounted on the outer mounting shaft through a bearing. An arc-shaped notch 337 with an upwardly concave groove wall is formed at the lower end of the limiting side plate. The edge of the outer runner extends downward relative to the groove wall.

[0031] The working principle of the present utility model is as follows: First, set the required number of limit members 3 on the mounting rod 21, then fixedly connect both ends of the mounting rod to the support base, and then fix the support base above the frame. Subsequently, adjust the positions of the limit members so that the limit members are aligned one by one with the winding positions of the strip film on the peeling roller. After the alignment is completed, make the limit members relatively fixed to the mounting rod through the locking member 313, that is, complete the preparatory work before peeling and winding; when the winding starts, the limiting portion 33 overlaps above the peeling roller, contacts the peeling roller through the outer rotating wheel and undergoes rolling friction, avoiding direct friction between the peeling roller and the lower end of the limit side plate. When the diameter of the reel gradually increases and pushes up the limiting portion, the inner rotating wheel contacts the circumferential edge of the reel and undergoes rolling friction, avoiding direct friction between the reel and the top plate. During the winding process, the two limit side plates always remain on both sides of the edge part of the reel, avoiding excessive deviation of the newly wound strip film; after the winding is completed, remove the mounting frame from the upper end of the frame, and then separate one end of the peeling roller from the frame, and several reels on the peeling roller can be taken off.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
