All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Example 1

[0026] Please see Figure 2-9 One embodiment of this utility model is a decorative strip punching device, including a frame 4;

[0027] For easy movement, the bottom of the frame 4 is equipped with a universal caster 20 on all four sides;

[0028] To facilitate later maintenance, a front cabinet door 21 is hinged to the front of the frame 4, and a rear cabinet door 22 is hinged to the rear of the frame 4.

[0029] A workbench panel 2 is provided above the frame 4. A decorative strip fixing plate 3 for fixing the decorative strip 1 is provided on the workbench panel 2. A limiting groove 5 for placing and fixing the decorative strip 1 is provided on the decorative strip fixing plate 3. A fixing support 6 is provided inside the frame 4.

[0030] In order to facilitate pressing the decorative strip 1 and prevent the decorative strip 1 from moving randomly during cutting and affecting the flatness of the cutting, a second flip cylinder 12 is also provided on the workbench panel 2, located on both sides of the decorative strip fixing plate 3. The output end of the second flip cylinder 12 is connected to a silicone pressure block 13 that can press the decorative strip into the limiting groove 5 after flipping.

[0031] The fixed support 6 is provided with two parallel guide rails 7. A shearing assembly 8 for cutting the connecting strip is slidably connected between the two guide rails 7. The shearing assembly 8 includes a first cylinder 801, a sliding plate 802, a positioning plate 803, and one or more pneumatic scissors 804. The bottom of the sliding plate 802 is slidably connected between the two guide rails 7. The positioning plate 803 is parallel to the sliding plate 802 and located above the sliding plate 802. The first cylinder 801 is fixed to the side of the fixed support 6, and the piston rod of the first cylinder 801 is connected to the bottom of the sliding plate 802 through a sliding seat 805. The distribution of each pneumatic scissor 804 is determined according to the cutting point of the connecting strip to be cut. The decorative strip fixing plate 3 is provided with a through groove 23 to facilitate the insertion of the pneumatic scissors 804. A pneumatic scissor is also provided in the frame 4. An air supply device 9 for supplying air to pneumatic scissors 804 is provided. An air pump 10 is located at the rear of the frame 4, connecting the pneumatic scissors 804 and the air supply device 9. A second cylinder 11 is fixed at the center of the slide plate 802. The piston rod of the second cylinder 11 is connected to the bottom of the positioning plate 803. For guiding purposes, four guide rods 14 are arranged on the slide plate 802, distributed front, back, left, and right. Four guide slides 15 are respectively fitted onto the corresponding guide rods 14 on the positioning plate 803. Each pneumatic scissor 804 is fixed to a connecting seat 16. The connecting seat 16 is fixed to the positioning plate 803 by a positioning rod 17. For easy flipping, the connecting seat 16 is fixed to a flipping cylinder 18, which is fixed to one end of the positioning rod 17. In this embodiment... Figure 10 As shown, after the two decorative strips 1 are formed, 7 connecting strips 101 will be generated, so 10 cutting points BK need to be generated. Therefore, 6 pneumatic shears 804 need to be set up later and distributed according to these 10 cutting points. If the two decorative strips 1 are formed later, there are only two connecting strips 101 in the middle, so the cutting component 19 can be used directly, with only four cutting points. At the same time, an operation switch is set at the front end of the frame 4 for convenient user operation.

[0032] Preferably, to achieve equipment versatility, a shearing assembly 2 19 for cutting the connecting strip is slidably connected between the two guide rails 7. The shearing assembly 2 19 includes a sliding plate 2 192, a positioning plate 2 193, and four pneumatic shears 2 197. The bottom of the sliding plate 2 192 is slidably connected between the two guide rails 7. The positioning plate 2 193 is parallel to the sliding plate 2 192 and located above it. Four guide rods 2 194 are arranged on the sliding plate 2 192, distributed front-back, left-right. Four guide slides 2 195 are respectively fitted onto the corresponding guide rods 2 194 on the positioning plate 2 193. Each pneumatic shear 2 197 is fixed to a connecting seat 2 196, which is fixed to a tilting cylinder 3 198. The third cylinder 191 is fixed at the center of the second slide plate 192, which is fixed on one end of the positioning rod 199. The piston rod of the third cylinder 191 is connected to the bottom of the positioning plate 193. During operation, the first cylinder 801 is in the maximum progress state to ensure that the first slide plate 802 is moved to the leftmost position. Then, the second slide plate 192 is manually moved to the bottom of the through groove 23. Then, the third cylinder 191 is driven to work to ensure that each pneumatic scissors 197 can pass through the through groove 23. Then, the product is placed in the limiting groove 5. The two sides are flipped by the two flipping cylinders 12 to make the silicone pressure block 13 press the two decorative strips 1. At this time, the third cylinder 191 works to move the pneumatic scissors 197 upward and drive the pneumatic scissors 197 to work to automatically and quickly cut the connection between the corresponding connecting strip 101 and the decorative part 1.

[0033] The specific working principle of this structure is as follows: The injection-molded finished product is then... Figure 10 The structure shown is placed in the two limiting grooves 5 of the decorative strip fixing plate 3. Then, the two rotating cylinders 12 on both sides are driven to rotate, so that the silicone pressure block 13 presses the two decorative strips 1 respectively. In the initial state, the shearing component 8 is located on the far right, and each rotating cylinder 18 is in the initial state, that is, ensuring that each pneumatic scissor 804 is flipped outward. Then, the first cylinder 801 is driven to work, driving the slide plate 802 to move below the decorative strip fixing plate 3. Then, the rotating cylinder 18 is driven to work, rotating each pneumatic scissor 804 90 degrees to a vertical state, that is, with the clamp facing upward. The second cylinder 11 is driven to work, driving the positioning plate 803 to move upward, ensuring that each pneumatic scissor 804 can pass through the through groove 23. This ensures that at each shearing point, each pneumatic scissor 804 works simultaneously to shear at each shearing point, ultimately forming an independent decorative strip 1. Figure 1 The state shown is sufficient. Therefore, this structure enables automatic cutting of excess parts on the decorative strip 1, and the cutting is done simultaneously, further improving work efficiency.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
