Description

Technical Field

[0001] This utility model relates to the field of pre-coated film material extrusion, and more specifically, to a pre-coated film material extrusion mechanism. Background Technology

[0002] Pre-coated film refers to the process of applying adhesive to a plastic film beforehand, rewinding it, and then laminating it with paper printed materials. First, the pre-coated film processing plant applies adhesive to the film according to the specifications and size required, rewinds it, and then provides it to the user for selection. Then, it is laminated with the printed materials. Lamination, or film application, involves applying adhesive to a plastic film and bonding it to the paper printed materials through heating and pressure, forming a paper-plastic composite product. Laminated printed materials have an additional thin, transparent plastic film on their surface, resulting in a smoother and glossier surface, thus improving the gloss and durability of the printed materials. The colors and graphics are more vibrant and three-dimensional, while also providing waterproofing, stain resistance, wear resistance, folding resistance, and chemical corrosion resistance.

[0003] A search revealed that the existing Chinese utility model patent (application number: CN212554956U) discloses "A Pre-coated Film Extrusion Composite Machine with Easy Installation," whose specification states that it includes multiple sets of two support bases, an extrusion composite machine body, a feeding device, a crushing body, a storage box, a feeding funnel, two sets of pallets, two sets of first motors, two sets of rotating rollers, multiple sets of crushing teeth, a first screen plate, and a second screen plate. The two sets of support bases are symmetrically fixed at the bottom of the extrusion composite machine body. The top of the extrusion composite machine body is provided with a feeding port, and the feeding device is connected to the feeding port. The crushing body is connected to the feeding device, and the crushing body has a crushing chamber inside. The storage box is fixed on the top left side of the crushing body and is connected to the crushing chamber of the crushing body.

[0004] Although the aforementioned patent can adsorb dust from the device, the aforementioned filter plate still has the following problems: the existing screening structure uses a fixed screen plate to screen raw material particles, but the fixed screen plate relies on the material's own weight to fall, resulting in low screening efficiency and difficulty in completely separating particles with uneven particle sizes. In particular, when the raw material contains larger particles, the fixed screen plate is prone to blockage due to material accumulation, causing some large particles that are not fully crushed to still enter the extrusion chamber.

[0005] Therefore, we have made improvements to this by proposing a pre-coated film raw material extrusion mechanism. Utility Model Content

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A pre-coated film raw material extrusion mechanism includes a mechanism body 1, a crushing body 2 on the top of the mechanism body 1, a fixing block 3 fixedly connected to one side of the crushing body 2, a motor 4 fixedly connected to one side of the fixing block 3, a transmission groove 15 inside the fixing block 3, and two first sprockets 6 and second sprockets 8 inside the transmission groove 15.

[0024] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the crushing body 2 has two rotating disks 10 inside. One side of the rotating disk 10 is fixedly connected to one side of the first sprocket 6. A connecting rod 11 is rotatably connected to the side of the rotating disk 10 away from the first sprocket 6. A transmission block 12 is rotatably connected to the side of the connecting rod 11 away from the rotating disk 10. A screen frame 14 is fixedly connected to the side of the transmission block 12 away from the connecting rod 11. A screen plate 20 is provided at the bottom of the screen frame 14. The surface of the screen plate 20 is provided with screen holes, which can intercept large particles. A limiting block 13 is fixedly connected inside the crushing body 2. The inside of the limiting block 13 is slidably connected to the surface of the transmission block 12. By rotating the rotating disk 10, the connecting rod 11 is driven to pull the limiting block 13 to move horizontally back and forth under the restriction of the limiting block 13. At the same time, the internal screen frame 14 is driven to move horizontally back and forth, so that the material inside the screen frame 14 is vibrated and screened.

[0025] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a support block 23 is fixedly connected inside the crushing body 2. The cross-section of the support block 23 is T-shaped. A groove 16 is opened inside the support block 23. A slider 18 is slidably connected inside the groove 16.

[0026] Example 2 The pre-coated film raw material extrusion mechanism provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a trapezoidal block 21 is fixedly connected to the bottom of the screen frame 14, and a trapezoidal groove 22 is provided on the surface of the screen plate 20. The interior of the trapezoidal groove 22 is slidably connected to the surface of the trapezoidal block 21. The screen plate 20 is fixedly installed to the screen frame 14 by bolts. A side plate 5 is fixedly installed on one side of the crushing body 2 by bolts. The side plate 5 is removed by bolts, and then the screen plate 20 is fixed in contact by bolts. Then the screen plate 20 is slid out through the trapezoidal groove 22 for easy replacement and cleaning.

[0027] The usage process of the pre-coated film raw material extrusion mechanism provided by this utility model is as follows: When the staff needs to screen the materials, the motor 4 is started, which causes the chain 7 on the surface of the first sprocket 6 to drive the second sprocket 8 on one side. At the same time, the transmission rod 9 on one side of the second sprocket 8 rotates, so that the first sprocket 6 and the second sprocket 8 on both sides are driven synchronously. Then, the rotating disk 10 on one side of the first sprocket 6 rotates, which drives the connecting rod 11 on the other side to drive the transmission block 12 to perform horizontal reciprocating motion inside the limiting block 13, thus screening the materials on the surface of the screen plate 20. At the same time, the scraper 19 on the surface of the screen plate 20 can agitate the materials on the surface of the screen plate 20, so that the materials can be evenly distributed on the surface of the screen plate 20, increasing the screening efficiency.

[0028] When the staff needs to disassemble and clean the screen plate 20, the side plate 5 is removed by bolts, and then the screen plate 20 is fixed in contact by bolts. Then the screen plate 20 is slid out through the trapezoidal groove 22 for easy replacement and cleaning.
