Description

Technical Field

[0001] This utility model belongs to the field of die-cutting technology, specifically relating to a circular die-cutting assembly that prevents the blade from sticking to adhesive. Background Technology

[0002] In the field of die-cutting, rotary die-cutting sets are widely used for cutting and shaping adhesive products such as tapes, labels, and films. However, in practical applications, especially when die-cutting adhesive materials (such as pressure-sensitive adhesives and hot melt adhesives), the adhesiveness of the glue can cause some glue to remain on the blade or surface of the rotary die. Long-term accumulation not only affects the smoothness and sharpness of the die, but also reduces the die-cutting quality and may even lead to problems such as burrs on the product edges and dimensional deviations.

[0003] Currently, the main method to reduce adhesive adhesion is to manually apply release agents (such as silicone oil, fluorine coatings, etc.). However, manual operation requires frequent machine stops for application, which affects the continuity of each production line station in die-cutting production. Furthermore, manual application makes it difficult to ensure the uniformity of release agent coverage, leading to localized adhesive sticking or coating waste. Excessive use can also cause contamination of products and production equipment. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figs. 1-3The circular die-cutting assembly for preventing adhesive from sticking to the blade includes a base plate 1. A liquid storage tank 2 is placed on the front top of the base plate 1. First fixing rods 3 are located on both sides of the liquid storage tank 2 on the top of the base plate 1. Slider blocks 4 are rotatably mounted on the upper part of each of the first fixing rods 3. Slide plates 5 are slidably connected between the sliders 4. Mounting rods 6 are installed between the rear sides of the slide plates 5. Mounting plates 7 are installed behind the mounting rods 6. Foam blocks 8 are detachably mounted on the mounting plates 7. Second fixing rods 9 are symmetrically arranged on the middle top of the base plate 1. Third fixing rods 10 are symmetrically arranged on the rear top of the base plate 1. Circular die 11 is rotatably connected between the upper parts of the third fixing rods 10. A first shaft 12 is rotatably connected between the fixed rods 9. A first swing rod 13 is symmetrically arranged on the first shaft 12. The upper part of the first swing rod 13 is rotatably connected to the rear part of the slide plate 5 through a second shaft 14. A drive plate 15 is provided on the right side of the circular knife mold 11. A circular arc groove 16 and a circular rod groove 17 are intermittently provided on the drive plate 15. A third shaft 18 is rotatably arranged in the middle of the third fixed rod 10. A swing rod group 19 is connected between the left side of the third shaft 18 and the first shaft 12. A circular arc plate 20 is connected to the right side of the third shaft 18. A second swing rod 21 is arranged on the third shaft 18 at the position to the right of the circular arc plate 20. A circular rod 22 is connected to the inner side of the lower part of the second swing rod 21.

[0021] This invention effectively prevents glue from adhering to the blade or surface of the circular die 11 by automatically applying release agent, avoiding problems such as reduced die-cutting quality due to glue residue, including burrs on product edges and dimensional deviations. This invention eliminates the need for frequent manual stoppages for application, avoiding the tediousness and instability of manual operation and improving the continuity of the production process. The mounting plate 7 in this invention adopts a Velcro design, allowing for quick replacement of foam blocks 8 according to different blade shapes, layouts, and sizes, adapting to different die-cutting needs and improving the flexibility and production efficiency of the equipment.

[0022] Example 2

[0023] like Figs. 1-3 The circular die-cutting assembly shown includes a base plate 1 with a hollowed-out center. The hollowed-out area can be used to place a liquid collection tank to collect the liquid dripping when applying release agent to the blade, saving maintenance costs and preventing long-term liquid accumulation from affecting the working environment. A liquid storage tank 2 is placed on the front top of the base plate 1, containing release agent. Correspondingly, a third fixing rod 10 is symmetrically arranged on the rear top of the base plate 1. A circular die 11 with 8 blades is rotatably connected to the upper part of the third fixing rod 10. Then, simply use a foam block 8 to pick up the release agent in the liquid storage tank 2 and then attach it to the blade to complete the application of release agent, thus achieving the effect of preventing the blade from sticking.

[0024] Based on the design of the above 8 sets of blades, this embodiment provides a drive plate 15 on the right side of the circular blade mold 11. The drive plate 15 is also circular in shape, and the same number of arc grooves 16 and rod grooves 17 are intermittently provided on the edge of the drive plate 15. There are 8 arc grooves 16 and 8 rod grooves 17, and the arc grooves 16 correspond to the blade positions of the circular blade mold 11 in sequence. In practical applications, the drive plate 15 can be rotated regularly to drive each set of blades to stop stably in the designated position in sequence. At this time, the foam block 8 with release agent can be applied to the blades.

[0025] The top of the base plate 1 is provided with first fixing rods 3 on both sides of the liquid storage tank 2. Each first fixing rod 3 has a slider 4 rotatably mounted on its upper part. The sliders 4 are slidably connected by a sliding plate 5, that is, the sliding plate 5 slides with the slider 4 through a groove. An installation rod 6 is installed between the rear sides of the sliding plate 5. An installation plate 7 is provided on the rear side of the installation rod 6. The installation plate 7 has Velcro on the side away from the installation rod 6. Foam blocks 8 are installed through the Velcro. Thus, the staff can replace the foam blocks 8 in advance according to the shape, layout and size of each set of blades, making the device more flexible.

[0026] The top center of the base plate 1 is symmetrically provided with second fixing rods 9. The second fixing rods 9 are rotatably connected to the first shaft 12. The first shaft 12 is symmetrically provided with first swing rods 13. The upper part of the first swing rod 13 is rotatably connected to the rear part of the slide plate 5 through the second shaft 14. Thus, by rotating the first swing rod 13, the lower part of the mounting plate 7 can be driven to swing, thereby driving the foam block 8 installed on it to swing. The swing is a right angle arc of more than 90°. That is, the mounting plate 7 drives the foam block 8 below to insert into the liquid storage tank 2 in a vertical state to pick up the release agent, and then swings 90° backward, driving the mounting plate 7 in a horizontal state to drive the foam block 8 behind it to apply the blade.

[0027] A third shaft 18 is rotatably mounted in the middle of the third fixed rod 10. A rocker arm assembly 19 is connected between the left side of the third shaft 18 and the first shaft 12. The rocker arm assembly 19 is composed of three connected rocker arms and is mainly used to consume the stroke of the third shaft 18. Specifically, an arc plate 20 is connected to the right side of the third shaft 18. A second rocker arm 21 is located on the third shaft 18 to the right of the arc plate 20. A round rod 22 is connected to the lower inner side of the second rocker arm 21. When the third shaft 18 rotates one revolution, it causes the round rod 22 to engage with the round rod groove 17, thereby causing the drive plate 15 and the die-cutting blade assembly to rotate by a specified angle. Then, the arc plate 20 engages with the arc groove 16 to avoid... The driverless board 15 and the die-cutting blade assembly rotate to maintain a designated state, i.e., a certain set of blades faces forward. While the die-cutting blade assembly rotates, it also drives the first shaft 12 to swing for a designated stroke through the swing arm assembly 19. This swing stroke can drive the first swing arm 13 to swing forward until the foam block 8 on the mounting plate 7 is inserted vertically into the liquid storage tank 2 to pick up the release agent. When the die-cutting blade assembly stops rotating, the third shaft 18 continues to rotate and drives the first shaft 12 to swing backward through the swing arm assembly 19, applying the release agent to the blades facing forward in a horizontal state, completing one operation. This process is repeated until all 8 sets of blades are coated.
