[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0049] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] like Figures 1 to 8 As shown, the adhesive head of the utility model is used to process an easy-tear edge on the adhesive tape 10, and cut it into a certain length to be attached to the product. Specifically, it includes a base plate 20 for structural connection, a reeling mechanism 30 for reeling the adhesive tape 10, a processing mechanism 40 for processing the easy-tear edge and punching holes, and a cutting mechanism 50 for cutting the adhesive tape 10.

[0051] See also Figure 1-3 As shown, the unwinding mechanism 30 is rotatably connected to the front end surface of the base plate 20; the unwinding mechanism 30 includes an unwinding shaft 31 rotatably connected to the base plate 20, a first baffle 32 mounted on the unwinding shaft 31, and a second baffle 33 mounted on the unwinding shaft 31. A receiving cavity 34 is formed between the first baffle 32 and the second baffle 33, and the adhesive tape 10 to be processed is wound in the receiving cavity 34. A retaining ring 331 is provided on the second baffle 33, and an adjustable handle 35 is provided on the retaining ring 331. Correspondingly, a level position 311 is provided on the outer wall of the unwinding shaft 31. The adjustable handle 35 is tightened so that the lower end of the adjustable handle 35 abuts against the level position 311 to lock the second baffle 33; on the contrary, the adjustable handle 35 is loosened, and the second baffle 33 can move along the length direction of the unwinding shaft 31 to adjust the size of the receiving cavity 34, thereby adapting to adhesive tapes 10 of different sizes. The rear end of the unwinding shaft 31 passes through the base plate 20 and is fixed with a brake wheel 312. A brake belt 36 abuts against the outer wall of the brake wheel 312. The friction between the outer wall of the brake wheel 312 and the brake belt 36 increases the rotation resistance of the unwinding shaft 31, thereby avoiding excessive unwinding speed.

[0052] See also Figure 4 As shown, the processing mechanism 40 includes a mounting base plate 41 fixed to the front end surface of the substrate 20, a knife pillow 42 horizontally mounted on the front end of the mounting base plate 41, a rubber cutting assembly 43 mounted below the knife pillow 42, and a punching assembly 44 mounted below the knife pillow 42; the rubber cutting assembly 43 is used to cut the rubber on the tape 10 to form an easy-tear opening, and the punching assembly 44 is used to punch a marking hole 13 at the easy-tear opening of the tape 10.

[0053] Specifically, the rubber cutting assembly 43 includes a first driving element 431 assembled and connected to the mounting base plate 41, a movable seat 432 driven and connected to the upper end of the first driving element 431, and two blades 433 symmetrically arranged on the upper end surface of the movable seat 432, and the blades 433 are arranged in parallel. The punching assembly 44 includes a second driving element 441 assembled and connected to the mounting base plate 41, and a punch 442 driven and connected to the second driving element 441; the punch 442 is arranged vertically, and the second driving element 441 drives the punch 442 to punch vertically upward. In this embodiment, the first driving element 431 and the second driving element 441 are both cylinders.

[0054] like Fig. 9 As shown, the tape 10 moves to the bottom of the knife pillow 42, wherein the tape 10 is composed of a sticky substrate 11 and a release paper 12, at this time the substrate 11 is facing downward, the first driving element 431 drives the movable seat 432 and the blade 433 to approach the tape 10 to cut the substrate 11, and at the same time, due to the stickiness of the substrate 11, the substrate 11 adheres to the movable seat 432 and separates from the release paper 12, forming an easy-tear opening. At the same time, the second driving element 441 drives the punch 442 to move upward, and processes the identification hole 13 at the portion of the easy-tear opening of the tape 10.

[0055] Furthermore, the first driving element 431 is tilted, and the first driving element 431 drives the movable seat 432 and the blade 433 to move upward. The oblique cutting method can reduce the influence of viscosity and avoid the substrate 11 sticking to the blade 433 during the cutting process, which affects the processing of the easy-tear edge.

[0056] See also Figure 5-8 As shown, the cutting mechanism 50 includes a connection seat 51 fixed to the front end of the base plate 20, an optical fiber sensor 52 fixed to the connection seat 51, and a cutter assembly 53 fixed to the connection seat 51; a rubber sticking wheel 54 is provided at the lower end of the connection seat 51. The cutter assembly 53 includes an upper cutter 531 fixed to the lower end of the connection seat 51, a lower cutter 532 arranged opposite to the upper cutter 531, and a third driving element 533 fixed to the side of the connection seat 51; the third driving element 533 is drivingly connected to the lower cutter 532.

[0057] The tape 10 with the easy-tear edge and the identification hole 13 processed enters the cutting mechanism 50, and one end of the tape 10 passes over the adhesive wheel 54 and is attached to the product. The optical fiber sensor 52 recognizes the identification hole 13 on the tape 10 and sends a start electrical signal to the third driving element 533, which drives the lower cutter 532 to move toward the upper cutter 531 to cut the tape 10.

[0058] Furthermore, the front end surface of the base plate 20 is provided with a rotatably connected swing arm 60, and the cutting mechanism 50 is assembled on the swing arm 60; a telescopic cylinder 61 is fixedly provided on the base plate 20, and the telescopic cylinder 61 is provided with a transmission-connected connecting rod 62, and the lower end of the connecting rod 62 is fixedly connected to the swing arm 60; the telescopic cylinder 61 drives the swing arm 60 to swing up and down, and the swing arm 60 is pressed downward so that the adhesive wheel 54 can press the tape 10 onto the product.

[0059] Furthermore, the cutting mechanism 50 also includes a glue pressing assembly 55; the glue pressing assembly 55 includes a first slide cylinder 551 fixed on the swing arm 60, a second slide cylinder 552 drivingly connected to the lower end of the first slide cylinder 551, and a pressure plate 553 drivingly connected to the second slide cylinder 552; the pressure plate 553 is arranged on the rear side of the connecting seat 51, and the pressure plate 553 presses the tape 10 tightly against the rear side of the connecting seat 51 to prevent the tape 10 from loosening and affecting the quality of glue application; the first slide cylinder 551 drives the pressure plate 553 to move along the length direction of the swing arm 60, and the second slide cylinder 552 drives the pressure plate 553 to move along the width direction of the swing arm 60.

[0060] See also Figure 1-3 As shown, the adhesive tape head of the present invention further includes a roller assembly 70, which includes a plurality of rollers 71 rotatably connected to the front end surface of the substrate 20 and a plurality of traction wheels 72 rotatably connected to the front end surface of the substrate 20; the rear end of the traction wheel 72 penetrates the substrate 20 and is connected to a driving motor 73. Under the power traction of the traction wheel 72, the adhesive tape 10 is transported from the unwinding mechanism 30 to the processing mechanism 40, and finally to the cutting mechanism 50. The roller 71 is arranged on the substrate 20 to play the role of transition and maintaining tension.

[0061] Compared with the prior art, the glue-applying head involved in the utility model can automatically process an easy-tear edge on the adhesive tape and perform glue-applying and cutting, thereby improving glue-applying efficiency and accuracy; specifically, a processing mechanism and a cutting mechanism are provided; wherein the processing mechanism includes a glue-cutting assembly for cutting the adhesive to form an easy-tear edge and a punching assembly for punching a marking hole at the easy-tear edge; and the cutting mechanism includes an optical fiber sensor for sensing the marking hole and a cutter assembly for cutting the adhesive tape, the optical fiber sensor is electrically connected to the cutter assembly, and the mutual induction between the optical fiber sensor and the marking hole is used to ensure that the cutting length of the tape is consistent, thereby improving glue-applying accuracy.
