[0036] When the die-cutting equipment is started, the laminated double-sided adhesive tape and the bottom film are transmitted to below the die 14 by the transmission roller, and then the die 14 is driven up and down by the upper die plate 2 to complete the die-cutting process;

[0037] After a long time of die-cutting, when the equipment is stopped or the shift is changed, the die 14 can be horizontally turned by 180 degrees through the installation part, so that the die 14 faces upwards and extends into the installation part, and the glue removing assembly in the installation part removes the double-sided adhesive tape adhered to the cutting edge of the die 14, so that the sharpness of the die 14 is not affected, the double-sided adhesive tape is not lifted from the bottom film after die-cutting, the die-cutting quality is ensured, the double-sided adhesive tape is not adhered to the cutting edge after oxidation and solidification, the unevenness of the cutting edge of the die is avoided, the wear of the die during use is further reduced, and the service life of the die is prolonged.

[0038] In a preferred embodiment, the laminating assembly 6 and the front end material pulling assembly 5 are further included for laminating the double-sided adhesive tape and the bottom film, the laminating assembly 6 has two laminating rollers 7 with adjustable spacing through a cylinder 8, and the laminating assembly 6 further comprises an electric control part 4 for monitoring the pressure of the laminating rollers 7.

[0039] Referring to Figures 1-2 The double-sided adhesive tape and the bottom film are laminated through the two laminating rollers 7 on the laminating assembly 6, and the electric control part 4 can also control the cylinder 8 to adjust the spacing between the two laminating rollers 7 according to the pressure of the double-sided adhesive tape and the bottom film on the laminating rollers 7 during lamination, so as to ensure the quality, and a deviation correcting ring can be installed on the two laminating rollers 7 to ensure the lamination quality and the stability during transmission.

[0040] In one of the more preferred embodiments, the mounting portion comprises a fixed module 9 fixed to the bottom of the upper die plate 2, the bottom of the fixed module 9 is provided with an annular groove 10 for inserting the die knife 14, the outer walls of the two sides of the fixed module 9 are both fixed with vertical pipes 11, the inner walls of the vertical pipes 11 are vertically slidably installed with vertical rods 12, the side walls of the die knife seat 13 are respectively rotatably connected with the bottom ends of the two vertical rods 12, the outer walls of the vertical pipes 11 are also provided with screw holes, and the screw holes are installed with bolts for abutting against the vertical rods 12.

[0041] The mounting portion can be specifically referred to Figure 3 In the use process, that is, in the die cutting state, the two vertical rods 12 are located in the vertical pipes 11, and are fixed by the bolts, at this time, the back of the die knife seat 13 will be fixed against the fixed module 9;

[0042] When switching is needed, the bolts are loosened to release the fixing effect on the vertical rods 12, then the die knife seat 13 is pulled downward until it can be flipped, and after the flipping is completed, the die knife seat 13 is moved upward again to make the vertical rods 12 be retracted into the vertical pipes 11 and be fixed by the bolts again.

[0043] When the flipped die knife seat 13 is pushed back to be attached to the fixed module 9, the upper die plate 2 can be controlled to move downward, and then the lower die plate 3 can be used to press it back.

[0044] In one of the more preferred embodiments, an embodiment of the glue removing assembly is provided.

[0045] The glue removing assembly comprises a liquid storage cavity 16 provided in the fixed module 9 for storing the cleaning agent which can dissolve the double-sided adhesive tape, the inside of the fixed module 9 is provided with a liquid delivery pipe 17 which connects the liquid storage cavity 16 and the inner annular wall of the annular groove 10, and the liquid delivery pipe 17 is installed with a first electromagnetic valve 24, the inside of the fixed module 9 is also provided with a liquid return pipe 18 which connects the liquid storage cavity 16 and the outer annular wall of the annular groove 10, and the liquid return pipe 18 is installed with a second electromagnetic valve 25, and the inside of the fixed module 9 is also installed with a return pump 19 for pumping the cleaning agent in the liquid return pipe 18 back to the liquid storage cavity 16.

[0046] The inner wall of the annular groove 10 is slidably installed with a lifting ring 15, and the lifting ring 15 and the inner top of the annular groove 10 are installed with a telescopic cylinder.

[0047] The glue removing assembly can be specifically referred to Figure 3 , Figure 4 and Figure 6From the above, the die holder 13 is turned over and the die 14 is inserted into the annular groove 10, at which time the die holder 13 will close the outlet of the annular groove 10 to form a sealed space, at which time the first electromagnetic valve 24 is opened, and the telescopic cylinder drives the lifting ring 15 to move upwards, so that the annular groove 10 below generates negative pressure, and the cleaner in the storage cavity 16 is sucked into the annular groove 10, and the liquid level will immerse the blade part of the die 14 completely, as shown in Figure 6 The cleaner is used to soften and dissolve the double-sided tape at the blade to achieve the effect of cleaning the double-sided tape.

[0048] Then, after soaking and dissolving, the first electromagnetic valve 24 is closed, the second electromagnetic valve 25 is opened, and then the cleaner in the annular groove 10 is pumped back into the storage cavity 16 by the backflow pump 19, so as to clean next time.

[0049] In one of the more preferred embodiments, the blade part of the die 14 is further detected and processed on the basis of the above embodiment;

[0050] The bottom of the lifting ring 15 is fixed with a fitting ring 22, the fitting ring 22 is made of soft material, and the fitting ring 22 can tightly fit with the inner ring wall of the die 14. The inside of the lifting ring 15 is provided with a storage cavity 20, and the storage cavity 20 contains powdered water-absorbing resin. The connection between the fitting ring 22 and the lifting ring 15 is provided with a plurality of annularly distributed air holes 23, and the inside of the lifting ring 15 is provided with a discharge hole 21 corresponding to the storage cavity 20 and the air holes 23.

[0051] Referring to Figure 4 After the cleaner dissolves the double-sided tape at the blade of the die 14, the first electromagnetic valve 24 is opened first, and the telescopic cylinder drives the lifting ring 15 to move downwards. With the decrease of the space in the annular groove 10, the cleaner in the annular groove 10 will flow back to the storage cavity 16 through the infusion tube 17 under the action of pressure, as shown in Figure 4 The inner ring part of the die 14 is set as a cavity C, and the outer ring part is set as a cavity B. At this time, the cleaner in the cavity C will be left due to the blockage of the die 14, and the liquid level is flush with the blade of the die 14.

[0052] When the lifting ring 15 is lowered to contact the blade of the die 14, the lifting ring 15 stops moving, at this time, the second electromagnetic valve 25 is opened again, and the cleaning liquid in the cavity B is pumped out by the backflow pump 19, and as the cleaning liquid is pumped out, a negative pressure is generated in the cavity B, thereby generating a pressure difference between the cavity B and the cavity C, so that if the cleaning liquid in the infusion tube 17 backflows into the cavity C after a period of time, it indicates that there is a communication between the cavity B and the cavity C, which causes the air pressure in the cavity C to decrease, and the communication between the two is the wear position or the uneven position of the blade of the die 14;

[0053] If the infusion tube 17 does not backflow, it indicates that there is no communication between the cavity B and the cavity C, that is, the blade of the die 14 remains good or is maintained within the normal wear range.

[0054] In this way, whether the cleaning liquid backflows in the infusion tube 17 can detect the wear or unevenness of the blade of the die 14, so as to replace it in time;

[0055] Moreover, it is worth mentioning that when the lifting ring 15 contacts the blade of the die 14, the fitting ring 22 at the bottom of the lifting ring 15 also tightly fits the inner ring wall of the die 14, so when the blade of the die 14 is worn or uneven, air flow will occur at this position, that is, air will flow from the cavity C to the cavity B, and then flow through the air hole 23 at the corresponding position, and the air hole 21 connected with the air hole 23 will carry out the powder-shaped water-absorbing resin under the flow of air, and will be washed to the wear position of the blade by the air flow, and as known from the previous content, the cavity B is full of cleaning liquid, so the lifting ring 15 in the cavity B will be stained with cleaning liquid, and when the water-absorbing resin passes through or through the wear position of the blade, it will directly accumulate in the wear position of the blade due to the swelling of the water-absorbing resin, thereby marking the position, and also outlining the wear shape of the wear position;

[0056] In this way, after the die 14 is turned over by 180 degrees, the wear position and wear condition of the die 14 can be detected by the marking on the blade of the die 14, and the possible wear reason can also be found according to the corresponding position of the wear, so as to facilitate subsequent maintenance and improvement.

[0057] It is worth noting that this method can be used for frame-shaped or circular dies, and the corresponding annular groove 10 can also be changed in shape.

[0058] In a more preferred embodiment, the upper and lower surfaces of the die seat 13 are provided with convex rings 26, and the convex rings 26 can be inserted into the annular groove 10 and sealedly inserted, and the die 14 is fixed on one of the convex rings 26.

[0059] The convex ring 26 can be used to position the die holder 13 and seal the opening of the annular groove 10.

[0060] In a preferred embodiment, the inner ring and the outer ring of the convex ring 26 are provided with inclined surfaces.

[0061] As shown in Figure 4 The inclined surfaces can help the cleaning liquid to be recycled.

[0062] In a preferred embodiment, the lowest part of the inclined surfaces of the convex ring 26 is flush with the communication port of the annular groove 10, and the first electromagnetic valve 24 and the second electromagnetic valve 25 are located near the communication port.

[0063] In a preferred embodiment, the bottom of the fixed module 9 is provided with a groove, and the groove can accommodate the cushion foam of the die holder 13.

[0064] As shown in Figure 3 The groove can provide a storage space for the cushion foam, so that the convex ring 26 can completely seal the annular groove 10.

[0065] In a preferred embodiment, the inner bottom of the storage cavity 20 is provided with a tapered surface, and the outer wall of the lifting ring 15 is provided with a filling channel for filling the storage cavity 20 with material.

[0066] The standard parts used in the embodiment can be directly purchased from the market, and the non-standard structural parts according to the description and drawings can also be directly processed according to the existing technical knowledge without any doubt. The connection method of each part uses the mature conventional method in the existing technology, and the machinery, parts and equipment use the conventional model in the existing technology, so the specific description is not made here.

[0067] Although the embodiments of the present application have been shown and described, it is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
