Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cutting equipment for producing adhesive tapes. Background Art

[0002] Adhesive tape is a common office supply and is also widely used in various occasions, such as homes, schools, factories, etc. Its basic principle is to stick a strip of paper, cloth or plastic tape coated with adhesive on one side together through pressure. There are many types of adhesive tapes, each with its own characteristics and uses. For example, some adhesive tapes have strong adhesion, sufficient toughness, and excellent tensile resistance, and are suitable for leather goods, shoes and other parts that need to bear force; some adhesive tapes have good insulation properties, high voltage resistance, high temperature resistance, and high flame retardancy, and are widely used in the electronics and electrical industries. In general, adhesive tapes play an important role in our daily lives and help us complete various tasks.

[0003] The adhesive tape needs to be cut during production and processing. After retrieval, the Chinese patent application number is: CN202021397946.3, which discloses an automatic cutting device for tape winding, including a workbench, an installation box, a clamping mechanism and a shearing mechanism. The installation box, the clamping mechanism and the shearing mechanism are all arranged on the upper surface of the workbench, and a rotating shaft is arranged on the outer surface of the conversion shaft. The control panel is electrically connected to the air pump and the motor inside the workbench. The lifting and lowering of the lifting cylinder B can be controlled by the control panel, so that the cutter moves up and down to achieve the effect of automatic cutting, reduce the labor intensity of the workers, and improve the cutting efficiency. A mounting knife cylinder is sleeved on the outer surface of the connecting rod B, and a knife groove is arranged on the outer surface of the mounting knife cylinder. A cutter is arranged inside the knife groove, and fixing holes are arranged at both ends of the cutter. Locking bolts are arranged at both ends of the mounting knife cylinder. The mounting knife cylinder is connected to the cutter through the locking bolts and the fixing holes. The installation and disassembly of the cutter is relatively simple, which is convenient for removing the cutter for maintenance, and preventing the outer surface of the cutter from being adhered to the adhesive for too long, affecting the cutting quality and efficiency.

[0004] The above technical solution still has a defect, that is, it lacks the function of the tape. When cutting, the tape is easily wrinkled due to the external force of the blade, resulting in poor cutting effect. Therefore, we need to propose a cutting device for the production of adhesive tape.

DETAILED DESCRIPTION

[0026] 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.

[0027] Please refer to Figure 1-3 , the present utility model provides a technical solution:

[0028] A cutting device for the production of adhesive tapes, comprising:

[0029] A main structure; the main structure includes a base 1 with support legs and a conveying roller 2 installed on the base 1;

[0030] A cutting mechanism; the cutting mechanism includes a support plate 3, an upper moving plate 5 and a lower moving plate 6 arranged on the base 1. The support plate 3 is arranged in a U-shape. Guide rods 4 are symmetrically arranged between the support plate 3 and the base 1. The upper moving plate 5 and the lower moving plate 6 are both slidably installed on the guide rods 4. A upper knife holder 7 is arranged at the bottom of the upper moving plate 5, a blade 9 is installed at the bottom of the upper knife holder 7, a lower knife holder 8 is arranged at the top of the lower moving plate 6, and a cutting groove corresponding to the blade 9 is opened at the top of the lower knife holder 8;

[0031] It further includes a positioning mechanism for positioning the adhesive tape. The positioning mechanism includes two groups of pressing plates 10 respectively arranged on the upper knife holder 7 and the lower knife holder 8. Grooves 15 are opened on one side of the blade 9 of the upper knife holder 7 and one side of the cutting groove of the lower knife holder 8. The grooves 15 are adapted to the pressing plates 10. Slide grooves 13 are opened on both the upper knife holder 7 and the lower knife holder 8. A first compression spring 14 is arranged inside the slide grooves 13. A connecting rod 11 is arranged on one side of the pressing plate 10. The end parts of the connecting rods 11 on the two groups of pressing plates 10 respectively penetrate through the upper knife holder 7 and the lower knife holder 8, and the end parts of the connecting rods 11 on the two groups of pressing plates 10 respectively extend into the slide grooves 13 of the upper knife holder 7 and the slide grooves 13 of the lower knife holder 8. A limiting block 12 is arranged at one end of the connecting rod 11 located inside the slide. The first compression spring 14 abuts against one side of the limiting block 12.

[0032] During actual use, the tape is conveyed by the conveying roller 2. When the tape passes between the upper knife holder 7 and the lower knife holder 8, the upper and lower knife holders 8 are driven to move towards the middle through the driving mechanism until the blade 9 is inserted into the cutting groove. Before that, since positioning mechanisms are arranged on both the upper knife holder 7 and the lower knife holder 8, the pressing plates 10 on the upper and lower knife holders 8 contact the tape between the blades 9, and the two groups of pressing plates 10 always clamp the tape in the middle until the connecting rod 11 retracts into the slide groove 13 and the pressing plate 10 is embedded into the groove 15, thereby providing a flattening and positioning function for the tape.

[0033] Generally speaking, the structure of this device is simple and easy to use. Through the setting of the positioning mechanism, the tape can be flattened and positioned before being cut. After positioning, the blade 9 cuts, which can effectively avoid the problem of uneven stress and wrinkling of the tape during cutting, and ensure the flatness of the cut.

[0034] Please refer to Figure 2In order to drive the upper knife seat 7 and the lower knife seat 8 at the same time and make them move synchronously, the present application makes the following design:

[0035] It also includes a driving mechanism for driving the upper moving plate 5 and the lower moving plate 6;

[0036] The driving mechanism includes an upper motor 18 installed on the top of the support plate 3 and a lower motor 19 installed on the bottom of the base 1. The output ends of the upper motor 18 and the lower motor 19 are fixedly connected to the first swing arm 20. The end of the first swing arm 20 is hinged with a second swing arm 21. The ends of the two sets of second swing arms 21 are respectively hinged to the top of the upper moving plate 5 and the bottom of the lower moving plate 6. The top of the support plate 3 and the base 1 are both provided with a notch 22 for the first swing arm 20 and the second swing arm 21 to move.

[0037] In actual use, the upper motor 18 and the lower motor 19 are started synchronously to drive the first swing arm 20 to rotate. Since the end of the first swing arm 20 is hinged to the second swing arm 21, and the two sets of second swing arms 21 are respectively hinged to the upper movable plate 5 and the lower movable plate 6, the upper movable plate 5 and the lower movable plate 6 can be driven to move similarly on the guide rod 4, thereby realizing the cutting function;

[0038] When the angle between the first swing arm 20 and the second swing arm 21 is 90 degrees, the tape cutting operation is completed, and the upper motor 18 and the lower motor 19 are reversed to separate the blade 9 and the cutting groove;

[0039] When the blade 9 is inserted into the cutting groove, at this time, the contact surfaces of the upper blade seat 7 and the lower blade seat 8 and the top end of the conveying roller 2 are on the same horizontal line.

[0040] See also Figure 2 and Figure 4 In order to avoid the upper knife seat 7 and the lower knife seat 8 from having too much collision force when they come into contact and thus shortening the service life of the equipment, the present application also makes the following design:

[0041] Two groups of washers 16 made of rubber material are sleeved on the guide rod 4 between the upper movable plate 5 and the lower movable plate 6 , and a second compression spring 17 is sleeved on the guide rod 4 between the two groups of washers 16 .

[0042] By sleeved the rubber washer 16 and the second compression spring 17 on the guide rod 4, and the washer 16 and the second compression spring 17 are located between the upper movable plate 5 and the lower movable plate 6, when the upper knife seat 7 and the lower knife seat 8 are in contact, under the action of the second compression spring 17 and the washer 16, a certain buffering effect can be played, thereby avoiding excessive collision force and shortening the service life of the equipment.

[0043] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
