This mechanism is mainly based on the working principle of the die-cutting machine. Through tools such as steel knives, hardware molds, steel wires (or templates carved from steel plates), a certain pressure is applied under the action of the embossing plate to roll and cut the double-sided adhesive tape materials into the required shape or press out the required marks.

[0004] Although the above-mentioned existing technology can realize the indentation processing of double-sided tape, it is not possible to accurately determine the conveying speed and position of the double-sided tape in the actual working process, thereby failing to ensure that each die-cutting operation can accurately align with the predetermined position of the double-sided tape, resulting in inaccurate indentation. Therefore, it does not meet the existing needs. In this regard, we propose a die-cutting indentation mechanism. Utility Model Content

[0005] The utility model aims to provide a die-cutting creasing mechanism to solve the problem that the creasing mechanism proposed in the above background technology cannot accurately convey the speed and position of the double-sided adhesive tape, and thus cannot ensure that each die-cutting operation can accurately align with the predetermined position of the double-sided adhesive tape.

[0006] To achieve the above object, the utility model provides the following technical solutions: a die-cutting and creasing mechanism, comprising a shell, a creasing platform is arranged at the lower end of the shell, and a creasing mechanism is arranged above the creasing platform; and further comprising:

[0007] A fixing frame, which is welded and fixed to the upper end surface of the indentation mechanism, a lifting column is installed at the middle position of the upper end surface of the fixing frame, the upper end portion of the lifting column extends into the slide groove of the upper shell of the outer shell, a turntable is rotated in the inner cavity of the upper shell of the outer shell, a connecting arm is rotatably installed at an eccentric position on one side of the turntable, and the other end of the connecting arm is connected to the top of the lifting column through a rotating shaft;

[0008] A winding mechanism, which is mounted on a bracket in front of the housing, wherein a transmission gear is fixedly mounted on one end of a winding shaft in the winding mechanism, a sector gear rotatably connected to the front bracket of the housing is mounted on the rear end of the transmission gear, and an outer gear ring of the sector gear is meshed with the transmission gear;

[0009] The transmission shaft is fixedly mounted on the shaft on the other side of the turntable. One end of the transmission shaft and one end of the sector gear are both fixedly provided with pulleys, and the pulleys are matched through belt transmission.

[0010] Preferably, a first servo motor is fixedly mounted above one side of the housing, and an output shaft of the first servo motor is fixed to the transmission shaft via a coupling.

[0011] Preferably, the front and rear ends of the indentation mechanism are provided with auxiliary fixing mechanisms, and the auxiliary fixing mechanism includes a fixing cylinder, and the fixing cylinder is fixed to the indentation mechanism, and a movable rod is slidably installed inside the fixing cylinder and extends to the outside, and a pressure plate in contact with the double-sided tape is fixedly installed at the bottom of the movable rod, and a support spring is installed between the fixing cylinder and the movable rod.

[0012] Preferably, an adjustment seat is installed inside the indentation mechanism, and the adjustment seat and the indentation mechanism are slidably limited, a stud is rotatably installed at the middle position inside the indentation mechanism, the stud extends to the inside of the adjustment seat, and the stud is frictionally fitted with the inner screw hole of the adjustment seat, a second servo motor is installed at the middle position of the upper end surface of the indentation mechanism, and the output shaft of the second servo motor is connected to the stud.

[0013] Preferably, a creasing knife is installed at the bottom of the adjustment seat, and the creasing knife and the adjustment seat are fixed by screws.

[0014] Preferably, an unwinding mechanism is installed on the rear end bracket of the shell.

[0015] Preferably, guide rollers are installed at positions of the front and rear end brackets of the shell close to the shell.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model precisely controls the conveying speed and position of the double-sided adhesive tape through the linkage between the double-sided adhesive tape winding mechanism and the creasing mechanism. The linkage with the creasing mechanism makes the entire die-cutting process smoother and more efficient, reducing the time for downtime, waiting and manual adjustment. The linkage design can ensure that the double-sided adhesive tape always maintains a stable conveying state during the die-cutting process, avoiding the problem of cutting deviation or inaccurate creasing caused by unstable conveying. At the same time, the precise die-cutting and creasing operations can ensure that the shape and size of the double-sided adhesive tape meet the design requirements, thereby improving the qualified rate of the product.

[0018] 2. The utility model is provided with an auxiliary fixing mechanism. As the indentation mechanism descends, the pressure plate at the bottom of the movable rod will first contact the double-sided tape. As the indentation knife continues to approach the double-sided tape, the supporting spring also continues to contract, thereby improving the fixing effect of the pressure plate at the bottom of the movable rod on the double-sided tape. After the front and back of the double-sided tape are reinforced, the indentation knife contacts the double-sided tape, and under the action of pressure, the double-sided tape material is rolled and cut into a desired shape or pressed out with a desired mark. This structure can further improve the stability of the indentation work, thereby improving the indentation quality.

[0019] 3. The utility model is provided with a creasing knife height fine-adjusting mechanism. By turning on the second servo motor, its output shaft drives the stud to rotate. Under the friction with the screw hole in the adjustment seat, the creasing mechanism guides the adjustment seat to form a fine adjustment of the vertical distance of the adjustment seat, so as to adapt to double-sided adhesives of different thicknesses, avoid shallow creasing and affect the subsequent separation effect, and avoid excessive creasing and penetration of double-sided fabrics, resulting in a decrease in product quality.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-4 The utility model provides an embodiment: a die-cutting creasing mechanism, comprising a housing 1, a creasing platform 16 is arranged at the lower end of the housing 1, and a creasing mechanism 2 is arranged above the creasing platform 16; and further comprising:

[0027] A fixing frame 5 is welded and fixed on the upper end surface of the indentation mechanism 2. A lifting column 6 is installed at the middle position of the upper end surface of the fixing frame 5. The upper end portion of the lifting column 6 extends into the slide groove of the upper shell of the outer shell 1. A turntable 7 rotates in the inner cavity of the upper shell of the outer shell 1. A connecting arm 8 is rotatably installed at an eccentric position on one side of the turntable 7, and the other end of the connecting arm 8 is connected to the top of the lifting column 6 through a rotating shaft;

[0028] The winding mechanism 15 is mounted on a bracket in front of the housing 1. A transmission gear 14 is fixedly mounted on one end of the winding shaft of the winding mechanism 15. A sector gear 13 rotatably connected to the front bracket of the housing 1 is mounted on the rear end of the transmission gear 14. The outer gear ring of the sector gear 13 is meshed with the transmission gear 14.

[0029] The transmission shaft 9 is fixedly mounted on the shaft on the other side of the turntable 7 , and one end of the transmission shaft 9 and one end of the sector gear 13 are both fixedly provided with pulleys 11 , and the pulleys 11 are coupled to each other through a belt 12 .

[0030] When in use, turn on the first servo motor 10, on the one hand, drive the turntable 7 to rotate. Since one end of the connecting arm 8 is installed at the eccentric position of the turntable 7, and the other end is connected to the lifting column 6 which is vertically limited by the slide groove in the shell 1, the lifting column 6 is pulled by the connecting arm 8 to form a vertical movement, thereby driving the creasing mechanism 2 below to process the double-sided adhesive. On the other hand, pulleys 11 are installed at one end of the transmission shaft 9 and the fan gear 13. Under the action of the belt 12, the fan gear 13 is driven to rotate. When the outer tooth ring of the fan gear 13 contacts the transmission gear 14, the shaft inside the winding mechanism 15 can be driven to rotate through the transmission gear 14, thereby forming the movement of the double-sided adhesive. When the two lose engagement, the double-sided adhesive stops at this position, which is convenient for cooperating with the creasing mechanism 2 for creasing treatment. The intermittent transmission cooperates with the creasing mechanism 2 to accurately control the conveying speed and position of the double-sided adhesive, ensuring that each die-cutting operation can accurately align with the predetermined position of the double-sided adhesive.

[0031] See also Figure 1 A first servo motor 10 is fixedly mounted on the upper side of the housing 1 , and the output shaft of the first servo motor 10 is fixed to the transmission shaft 9 through a coupling. The first servo motor 10 serves as a driving source to realize the rotation of the transmission shaft 9 .

[0032] See also Figure 2The front and rear ends of the indentation mechanism 2 are both provided with auxiliary fixing mechanisms, which include a fixed cylinder 17, and the fixed cylinder 17 is fixed to the indentation mechanism 2, a movable rod 18 is slidably installed inside the fixed cylinder 17 and extends to the outside, and a pressure plate in contact with the double-sided tape is fixedly installed at the bottom of the movable rod 18, and a supporting spring 19 is installed between the fixed cylinder 17 and the movable rod 18. This structure can further improve the stability of the indentation work, thereby improving the indentation quality.

[0033] See also Figure 1 , Figure 2 and Figure 4 An adjusting seat 3 is installed inside the indentation mechanism 2, and the adjusting seat 3 and the indentation mechanism 2 are slidably limited. A stud 20 is rotatably installed at the middle position inside the indentation mechanism 2, and the stud 20 extends to the inside of the adjusting seat 3, and the stud 20 and the inner screw hole of the adjusting seat 3 are frictionally matched. A second servo motor 21 is installed at the middle position of the upper end surface of the indentation mechanism 2, and the output shaft of the second servo motor 21 is connected to the stud 20, so as to avoid the indentation being too shallow and affecting the subsequent separation effect, and at the same time avoid the indentation being too deep and penetrating the double fabric, resulting in a decrease in product quality.

[0034] See also Figure 1 A creasing knife 4 is installed at the bottom of the adjusting seat 3, and the creasing knife 4 is fixed to the adjusting seat 3 by screws.

[0035] See also Figure 2 A reeling mechanism is installed on the rear end bracket of the housing 1.

[0036] See also Figure 2 Guide rollers are installed at the positions of the front and rear end brackets of the shell 1 close to the shell 1.

[0037] Working principle: When in use, by turning on the second servo motor 21, its output shaft drives the stud 20 to rotate. Under the friction with the inner screw hole of the adjustment seat 3, the guiding effect of the indentation mechanism 2 on the adjustment seat 3 is cooperated to form a fine adjustment of the vertical distance of the adjustment seat 3, so as to adapt to double-sided adhesive tapes of different thicknesses. As the indentation mechanism 2 descends, the pressure plate at the bottom of the movable rod 18 will preferentially contact the double-sided adhesive tape. As the indentation knife 4 continues to approach the double-sided adhesive tape, the support spring 19 also continues to contract, thereby improving the fixing effect of the pressure plate at the bottom of the movable rod 18 on the double-sided adhesive tape. After the front and back of the double-sided adhesive tape are reinforced, the indentation knife 4 contacts the double-sided adhesive tape, and under the action of pressure, the double-sided adhesive tape material is rolled and cut into the required shape or pressed out with the required traces.
