Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the present application.

[0038] Referring to Figures 1-3The utility model provides a kind of adhesive tape paper tube positioning cutting mechanism, comprising: mechanism main body 100, detachably installed on the mechanism main body 100 adhesive tape paper tube alignment plate piece 200 and with the spacing arrangement of push tube device 300 of adhesive tape paper tube alignment plate piece 200, the diameter of the feed hole 201 matched with the adhesive tape paper tube is opened on the adhesive tape paper tube alignment plate piece 200, the feed hole 201 is coaxially arranged with push tube device 300, and the channel for adhesive tape paper tube to enter and position is formed between feed hole 201 and push tube device 300;

[0039] The side wall of one side of the adhesive tape paper tube alignment plate piece 200 is fixed with a cutting assembly 400, the cutting assembly 400 is fixed on the mechanism main body 100, and is parallel to the axis of the push tube device 300; the side wall of the other opposite side of the adhesive tape paper tube alignment plate piece 200 is fixed with an adhesive tape paper tube conveying piece 500, and the adhesive tape paper tube conveying piece 500 is arranged between the adhesive tape paper tube alignment plate piece 200 and the push tube device 300.

[0040] The adhesive tape paper tube conveying piece 500 has at least a plurality of lower sliding roller assemblies 505, the lower sliding roller assemblies 505 are slidingly installed on the side wall of the adhesive tape paper tube alignment plate piece 200 towards the push tube device 300 side, the axis core line of the lower sliding roller assemblies 505 is staggered with the axis core line of the push tube device 300, and the arc-shaped guide surface 506 is formed on the axial direction of the lower sliding roller assemblies 505, and the curvature of the arc-shaped guide surface 506 is slightly smaller than the pipe diameter of the adhesive tape paper tube.

[0041] In the embodiment, by directly fixing the cutting assembly 400 on the mechanism main body 100 and parallel to the axis of the push tube device 300, the cutting operation can be immediately performed when the adhesive tape paper tube is pushed to the cutting position, without additional movement or adjustment, improving the cutting effect in actual production and processing. At the same time, the feed hole 201 coaxially arranged with the push tube device 300 in the adhesive tape paper tube alignment plate piece 200 guides the conveying direction of the adhesive tape paper tube, so that the adhesive tape paper tube can be smoothly moved to the cutting area, and since the diameter of the feed hole 201 matches the paper tube pushed by the push tube device 300, the adhesive tape paper tube can be accurately positioned when entering the cutting area, ensuring that the adhesive tape paper tube does not deviate or shake during movement, further improving the precision and quality of cutting.

[0042] On the other hand, the lower sliding roller assembly 505 is arranged in a staggered manner with the pushing direction of the pusher 300, providing stable support and precise guidance for the tape paper tube during transportation. Specifically, when the tape paper tube is pushed forward by the pusher 300, the two side edges of the arc-shaped guide surface 506 in the lower sliding roller assembly 505 are in symmetrical linear contact with the outer wall of the tape paper tube, limiting the freedom of the tape paper tube in the vertical direction. The inner wall of the feeding hole 201 also contacts the outer wall of the tape paper tube, limiting the radial position of the tape paper tube, thus forming a "V-shaped groove + plane" constraint, so that the tape paper tube cannot rotate or tilt during pushing. Since the curvature of the arc-shaped guide surface 506 is slightly smaller than the diameter of the tape paper tube, when the tape paper tube moves on the lower sliding roller assembly 505, the arc-shaped guide surface 506 is in interference fit with the tube wall of the tape paper tube, and through the close contact between the arc-shaped guide surface 506 and the tube wall of the tape paper tube, the vibration and deviation during transportation are reduced, ensuring the stability and straightness of the tape paper tube during pushing. At the same time, uniform contact pressure is formed between the tape paper tube and the lower sliding roller assembly 505, reducing frictional resistance and wear.

[0043] Compared with the existing technology of transporting and positioning the tape paper tube by clamping jaws and sleeves, the "V-shaped groove + plane" constraint method is adopted in the present embodiment.

[0044] Specifically, although the clamping jaw and sleeve full-enclosure method in the prior art can achieve positioning and transportation of the tape paper tube to some extent, the contact area between the clamping jaw and sleeve and the tape paper tube is relatively large, resulting in increased friction. Therefore, a larger pushing force is required to move the tape paper tube, and in the long-term use process, the surface of the tape paper tube is easily damaged, affecting product quality. In addition, the clamping jaw and sleeve full-enclosure method is relatively complex in installation and adjustment. When different specifications of tape paper tubes need to be replaced, it often takes a lot of time and effort to adjust the position and size of the clamping jaw and sleeve to meet the new production requirements.

[0045] The "V-shaped groove + plane" constraint mode in the embodiment realizes accurate positioning and stable conveying of the adhesive tape tube through the ingenious cooperation of the arc-shaped guide surface 506 on the lower sliding roller assembly 505 and the inner wall of the feeding hole 201. On the one hand, this constraint mode can effectively reduce the vibration and deviation of the adhesive tape tube during conveying, thereby ensuring cutting accuracy. On the other hand, since the curvature of the arc-shaped guide surface 506 is slightly smaller than the diameter of the adhesive tape tube, uniform contact pressure is formed between the adhesive tape tube and the lower sliding roller assembly 505 and the feeding hole 201 during movement, thereby reducing frictional resistance and wear and prolonging the service life of the equipment. At the same time, when it is necessary to replace the adhesive tape tube specifications, the height position of the lower sliding roller assembly 505 can be adjusted through the lifting adjustment assembly 503, so that the new production requirements can be met, and the operation is simple and quick.

[0046] In addition, the lower sliding roller assembly 505 is installed on the adhesive tape tube alignment plate 200 through the lifting adjustment assembly 503, so that the height of the lower sliding roller assembly 505 can be flexibly adjusted according to adhesive tape tubes of different diameters, thereby improving the universality and applicability of the equipment. At the same time, by adjusting the height of the lower sliding roller assembly 505, it can be ensured that the adhesive tape tube always maintains coaxiality with the feeding hole 201 and the tube pusher 300 during conveying, thereby ensuring the accuracy and consistency of cutting.

[0047] Referring to Figure 4 In one of the embodiments, push air cylinders 101 are symmetrically arranged on both sides of the mechanism body 100, and the output ends of the push air cylinders 101 are fixedly connected with the adhesive tape tube conveying element 500.

[0048] The adhesive tape tube conveying element 500 comprises cantilever arms 501, the side walls of one side of the cantilever arms 501 are fixedly connected with the output ends of the push air cylinders 101, the other side of the cantilever arms 501 is slidably installed on both sides of the adhesive tape tube alignment plate 200 through the moving blocks 502, and the lifting adjustment assemblies 503 are fixedly arranged on the cantilever arms 501, and the lifting adjustment assemblies 503 are used to adjust the positions of the lower sliding roller assemblies 505 in the vertical direction, so as to adapt to adhesive tape tubes of different heights.

[0049] Referring to Figures 5-6 The lifting adjustment assembly 503 comprises a mounting top plate 5031, the mounting top plate 5031 is fixedly installed between the cantilever arms 501 on both sides, a connecting shaft 5032 is arranged on the mounting top plate 5031, threaded sections 5034 are formed at both ends of the connecting shaft 5032, and worm gears 5035 are arranged at the areas of both ends of the mounting top plate 5031 corresponding to the threaded sections 5034, the worm gears 5035 are meshed with the threaded sections 5034 on the connecting shaft 5032, a lifting lead screw 5033 is rotatably connected at the shaft center of the worm gear 5035, and the lifting lead screw 5033 is fixedly connected with the lower sliding roller assembly 505.

[0050] In this embodiment, the whole tape paper tube conveying element 500 is driven to move by the push cylinder 102, and the height of the lower sliding roller assembly 505 is accurately adjusted by the lifting adjustment assembly 503, which can quickly adapt to tape paper tubes of different diameters or heights, significantly improving the versatility and efficiency of the equipment. And through the sliding guide structure of the cantilever 501 and the moving block 502, the smooth transmission of the worm gear, and the interference fit design of the arc guide surface 506 of the lower sliding roller assembly 505, the frictional resistance and surface scratches during the conveying of the tape paper tube are reduced, prolonging the service life of the equipment and the tape paper tube.

[0051] On the other hand, the push cylinder 102 and the worm gear 5035 synchronous transmission structure arranged symmetrically ensure the movement accuracy of the tape paper tube conveying element 500 in the horizontal and vertical directions, so that the tape paper tube always maintains coaxial with the tube pusher 300 and the cutting assembly 400, thereby ensuring the consistency of the cutting position. At the same time, the height of the lower sliding roller assemblies 505 on both sides can be adjusted simultaneously by rotating a single connecting shaft 5032, simplifying the equipment adjustment process and reducing the complexity of manual operation.

[0052] In one embodiment, it further includes an upper sliding roller assembly 504, which has the same structure as the lower sliding roller assembly 505, and is fixed below the installation top plate 5031 and forms a symmetrical clamping structure with the lower sliding roller assembly 505. The interference fit between the double-arc guide surface 506 and the outer wall of the tape paper tube achieves full circumferential constraint of the tape paper tube, avoiding the rigid friction damage of traditional full-enclosing clamping jaws.

[0053] Further, the distance between the upper sliding roller assembly 504 and the lower sliding roller assembly 505 is adjusted synchronously by rotating the connecting shaft 5032 and the adjusting cylinder 5036 to adapt to tape paper tubes of different diameters and maintain their axis constant. By rotating a single connecting shaft 5032, tape paper tubes of different diameters can be quickly adapted, and the symmetrical movement of the upper and lower sliding roller assemblies during adjustment ensures the constant axis of the tape paper tube, avoiding the cutting position deviation caused by height deviation. And the symmetrical layout of the upper sliding roller assembly 504 and the lower sliding roller assembly 505 makes the tape paper tube bear force evenly, reducing the local wear of the single sliding roller.

[0054] In one embodiment, the tape tube alignment plate member 200 comprises: a first mounting cantilever 202 and a second mounting cantilever 203, which are symmetrically arranged on the mechanism body 100, and a paper tube alignment plate 204 is slidably arranged at the end of the first mounting cantilever 202 towards the tube pusher 300, and a tape tube pressing assembly 205 is slidably arranged at the end of the second mounting cantilever 203 towards the tube pusher 300, and a lower paper tube alignment plate 207 is arranged between the tape tube pressing assembly 205 and the mechanism body, and the lower paper tube alignment plate 207 is fixedly arranged inside the tape tube pressing assembly 205 by a jacking cylinder 208, and cooperates with the upper paper tube alignment plate 204 to form a clamping space, and the opposite surfaces of the upper paper tube alignment plate 204 and the lower paper tube alignment plate 205 are both provided with arc-shaped positioning grooves 206, and the arc-shaped positioning grooves 206 at the bottom of the upper paper tube alignment plate 204 and the arc-shaped positioning grooves 206 at the top of the lower paper tube alignment plate 205 jointly form a feeding hole 201.

[0055] Further, the arc-shaped positioning grooves 206 at the top of the lower paper tube alignment plate 205 are provided with vertically downward long key grooves 208, which are used for closely cooperating with the shape of the end of the tape tube, and when the tape tube is inserted into the feeding hole 201, the end thereof is embedded into the long key groove 208, and through the key groove and the shape complement of the tape tube, the rotation or shaking of the tape tube during cutting is prevented, so as to ensure the cutting accuracy and stability.

[0056] Referring to Figure 7 In one embodiment, the tape tube pressing assembly 205 comprises: an upper mounting plate 2051 and a lower mounting plate 2052, which are both arranged on the slide rail at the end of the second mounting cantilever 203 towards the tube pusher 300, and a screw rod jacking member 2053 is fixedly connected between the upper mounting plate 2051 and the lower mounting plate 2052, and the lower mounting plate 2052 is further connected with the driving member at the bottom of the mechanism body 100, so as to have the ability of axial lifting along the slide rail, and synchronously drive the displacement of the upper mounting plate 2051, and at least two groups of pressing wheels 2054 are arranged on the upper end surface of the upper mounting plate 2051 along the long axis direction thereof, and the two groups of pressing wheels 2054 are symmetrically arranged on both sides of the arc-shaped positioning groove 206.

[0057] Further, the screw rod jacking member 2053 comprises a lifting rod 2055 which is threadedly matched with the lower mounting plate 2052, and an adjusting hand wheel 2056 which drives the rotation of the lifting rod 2055.

[0058] In this embodiment, the pressing wheels 2054 on the upper mounting plate 2051 are lowered along the slide rail under the action of the screw jacking member 2053 and the driving member, gradually contact and apply pressure to the outer wall of the adhesive tape paper tube. Since the pressing wheels 2054 are symmetrically arranged on both sides of the arc-shaped positioning groove 206, they can simultaneously apply pressure to the adhesive tape paper tube from two directions, thereby ensuring that the adhesive tape paper tube does not move or shake laterally during the cutting process.

[0059] On the other hand, the outer surface of the pressing wheel 2054 is usually made of wear-resistant material, such as rubber or polyurethane, to prevent damage to the surface of the adhesive tape paper tube during pressing and to ensure good friction and stability.

[0060] It should be noted that in this document, the terms "comprise", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, device, article or adhesive tape paper tube positioning and cutting mechanism including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, device, article or adhesive tape paper tube positioning and cutting mechanism.
