[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] The embodiment of the present application discloses a cutting structure for a die-cutting device. Figure 1 The present invention relates to a method for producing a self-adhesive paper 2 for a user to carry out die-cutting. The method comprises the following steps: first, a bottom plate 1 and a horizontally arranged self-adhesive paper 2. The upper surface of the bottom plate 1 is fixed with guide rollers 3 for guiding the self-adhesive paper 2 near the left and right ends, and a bearing platform 4 for die-cutting the self-adhesive paper 2 is provided between the two guide rollers 3. The bearing platform 4 is arranged on the lower side of the self-adhesive paper 2, and a die-cutting seat 5 is provided on the upper side of the self-adhesive paper 2, and a die-cutting head 7 is fixed to the middle part of the lower surface of the die-cutting seat 5. The front and rear ends of the bearing platform 4 are equipped with lifting rods 8 that can move up and down, and the lower side of the bearing platform 4 is provided with a swing mechanism 9 for driving the lifting rods 8 to reciprocate up and down. The front and rear ends of the die-cutting seat 5 are fixed with an adjusting mechanism 6 for adjusting the height of the die-cutting seat 5, and the adjusting mechanism 6 is connected to the upper end of the lifting rod 8. The guide roller 3 guides the self-adhesive paper 2. At this time, the lifting rod 8 is driven by the swing mechanism 9 to reciprocate up and down, thereby driving the die-cutting seat 5 to reciprocate up and down. The die-cutting seat 5 that reciprocates up and down drives the die-cutting head 7 to die-cut.

[0036] Reference Figure 2, the lower surface of the die-cutting seat 5 is longitudinally provided with long strips of rubber blocks 51 near the left and right sides, and the lower end of the rubber block 51 is fixed with a pressing plate 52. The swing mechanism 9 drives the lifting rod 8 to drive the die-cutting seat 5 to move up and down, so that the die-cutting head 7 on the lower side of the die-cutting seat 5 can die-cut the self-adhesive paper 2. When the die-cutting seat 5 descends, the pressing plate 52 first contacts the self-adhesive paper 2 and presses it. At this time, the die-cutting seat 5 continues to descend, and the rubber block 51 begins to elastically contract, and the die-cutting knife 7 is pressed against the self-adhesive paper 2. The head 7 contacts the self-adhesive paper 2 and performs die-cutting. The rubber block 51 and the pressure plate 52 are used to press and fix the self-adhesive paper 2 in advance when the die-cutting head 7 has not yet die-cut, thereby effectively preventing the self-adhesive paper 2 from moving, thereby better ensuring the die-cutting accuracy of the self-adhesive paper 2. The die-cutting seat 5 is vertically interspersed with multiple contour screws 53 threadedly connected to the pressure plate 52. The contour screws 53 are used to pull the pressure plate 52 and guide the pressure plate 52 when it moves up and down through the contour screws 53.

[0037] Reference Figure 2 The adjusting mechanism 6 includes a fixing plate 61 fixed on the die-cutting seat 5, an adjusting motor 62 is fixed to the upper end of the fixing plate 61, and the output shaft of the lower end of the adjusting motor 62 passes through the fixing plate 61 to fix an adjusting screw 63 threadedly connected to the lifting rod 8. The adjusting motor 62 drives the adjusting screw 63 to rotate, and the rotating adjusting screw 63 is screwed on the lifting rod 8 to adjust the relative height between the die-cutting seat 5 and the lifting rod 8. The front and rear ends of the die-cutting seat 5 are provided with guide slots 54 for clamping the upper end of the lifting rod 8. The guide slots 54 are used to guide and clamp the upper end of the lifting rod 8.

[0038] Reference Figure 3 The upper end of the lifting rod 8 is fixed with an adjusting block 82, and one end of the adjusting block 82 is fixed with a block 81 that is stuck in the guide slot 54. The lower end of the lifting rod 8 is fixed with a horizontally arranged connecting sleeve 83, and the connecting sleeve 83 is set to an oblong shape. The connecting sleeve 83 is set to an oblong shape so that it can make way for the horizontal displacement of the eccentric shaft 94 when the eccentric shaft 94 makes eccentric movement. The lifting rod 8 is connected to the swing mechanism 9 by using the connecting sleeve 83 at the lower end so that the swing mechanism 9 swings and drives the lifting rod 8 to reciprocate up and down.

[0039] Reference Figure 4The swing mechanism 9 includes a longitudinally arranged transmission rod 92, the middle part of the transmission rod 92 is connected to a driving member 93, and a turntable 91 is fixed to the front and rear ends of the transmission rod 92, and an eccentric shaft 94 inserted in the connecting sleeve 83 is fixed on the opposite side of the two turntables 91. The eccentric shaft 94 is inserted in the inner side of the connecting sleeve 83. When the eccentric shaft 94 rotates eccentrically, the connecting sleeve 83 will be driven to move up and down. The transmission rod 92 rotates under the drive of the driving member 93, and the transmission rod 92 drives the turntable 91 to rotate. The turntable 91 drives the eccentric shaft 94 to swing eccentrically, thereby driving the lifting rod 8 to reciprocate up and down.

[0040] Reference Figure 5 The driving member 93 includes a driving motor 931 on the base plate 1 and a rotating gear 934 fixedly mounted on the transmission rod 92. A mounting plate 932 is fixed to the lower side of the driving motor 931, and a driving gear 933 engaged with the rotating gear 934 is fixed to the output shaft of the driving motor 931. The driving motor 931 drives the driving gear 933 to rotate, and the rotating driving gear 933 drives the rotating gear 934 to rotate, thereby driving the transmission rod 92 to rotate.

[0041] Reference Figure 6 Guide sleeves 41 are fixed to the front and rear ends of the carrying platform 4, and the carrying platform 4 guides the vertical lifting rod 8 through the guide sleeves 41 when it reciprocates up and down, and side plates 43 are fixed to the lower surface of the carrying platform 4 near the front and rear ends. Bearings 42 for rotatably mounting the transmission rod 92 are fixed on the side plates 43, and the transmission rod 92 is rotatably mounted on the side plates 43 using the bearings 42.

[0042] Reference Figure 7 The front and rear ends of the guide roller 3 are both provided with support plates 32, and the front and rear ends of the guide roller 3 are rotatably connected to the support plates 32 on both sides respectively. The guide roller 3 is installed with a retaining sleeve 31 with adjustable front and rear positions near the front and rear ends. The two retaining sleeves 31 block the edges of the self-adhesive paper 2 to prevent the self-adhesive paper 2 from being conveyed offset, and the front and rear positions of the two retaining sleeves 31 can be adjusted to meet the limit blocking requirements of self-adhesive papers 2 of different widths.

[0043] Reference Figure 8 The retaining sleeve 31 includes a mounting sleeve 311 that is sleeved on the guide roller 3. The retaining sleeve 31 is sleeved on the guide roller 3 through the mounting sleeve 311 for movable adjustment. A retaining ring 312 is fixed on the side of the mounting sleeve 311 facing the middle of the guide roller 3. The retaining ring 312 on the mounting sleeve 311 is used to limit the edge of the self-adhesive paper 2. A locking screw 313 is threadedly installed on the mounting sleeve 311, and the mounting sleeve 311 is locked and fixed by the locking screw 313.

[0044] The implementation principle of the cutting structure for a die-cutting device in an embodiment of the present application is as follows: when die-cutting the self-adhesive paper 2, the stop sleeve 31 on the guide roller 3 is adjusted so that the distance between the two stop sleeves 31 is the same as the width of the self-adhesive paper 2. At this time, the guide roller 3 is used to guide the self-adhesive paper 2. When the self-adhesive paper 2 passes between the die-cutting seat 5 and the supporting platform 4, the driving motor 931 drives the driving gear 933 to rotate, and the rotating driving gear 933 drives the rotating gear 934 to rotate, thereby driving the transmission rod 92 to rotate, and the transmission rod 92 drives the turntable 91 to rotate, and the turntable 91 drives the eccentric shaft 94 to swing eccentrically, and the eccentric shaft 94 swings eccentrically to drive the connecting sleeve 83 to drive the lifting rod 8 to reciprocate up and down, and the lifting rod 8 reciprocates up and down to drive the die-cutting seat 5 to reciprocate up and down, and the die-cutting seat 5 that reciprocates up and down drives the die-cutting head 7 to die-cut, thereby completing the die-cutting process of the self-adhesive paper 2.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
