Description

Technical Field

[0001] This utility model relates to the field of polylactic acid coated paper cup production technology, and more specifically, to a polylactic acid coated paper cup production guide mechanism. Background Technology

[0002] The production of polylactic acid (PLA) coated paper cups requires the use of base paper that meets food hygiene standards. Generally, the paper must possess certain strength, stiffness, and absorbency to ensure that the paper cups do not easily deform or leak during use. Common base paper materials include wood pulp paper and bamboo pulp paper, while polylactic acid (PLA) is a biodegradable thermoplastic polyester with good biocompatibility, mechanical properties, and processing performance. The PLA film used in the production of PLA coated paper cups is typically prepared through extrusion blown film or casting methods. The film's thickness, transparency, tensile strength, and other performance indicators are adjusted according to specific product requirements.

[0003] During the production of polylactic acid (PLA) coated paper cups, the raw materials for the paper cups need to be fed to the coating machine for coating. By pre-mixing colors and patterns, PLA coated paper cup prototypes with different effects can be obtained after coating. During the feeding process, the thickness and materials of the raw materials for different batches of products are different, which causes the tension of the raw materials to vary. This leads to wrinkles and loosening of the raw materials in the area below the coating machine, reducing the coating effect and the final quality of the paper cups. Utility Model Content

[0004] The purpose of this invention is to provide a polylactic acid coated paper cup production guiding mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a polylactic acid coated paper cup production guiding mechanism, including a support frame. A coating machine body is fixedly connected to the top of the support frame. Two baffles are symmetrically fixedly connected to the top of the support frame. Multiple guide rollers are rotatably connected between the side walls of the two baffles. An auxiliary adjustment mechanism is provided at the top of the support frame and between the two baffles. The auxiliary adjustment mechanism includes slide rails symmetrically fixedly connected to the side walls of the baffles. Sliding blocks are slidably connected to the outer walls of the slide rails. Adjusting rollers are rotatably connected between the side walls of the two sliding blocks. Connecting rods are hinged to the bottom outer walls of the two sliding blocks. A first crossbar is rotatably connected between the bottom side walls of the two connecting rods. An electric push rod is provided above the top of the support frame. The extended end of the electric push rod is fixedly connected to the outer wall of the first crossbar. Two sets of slide rails, sliding blocks, and adjusting rollers are symmetrically arranged. A second crossbar is fixedly connected between the outer walls of the two sets of sliding blocks.

[0006] As a further improvement to this technical solution, the connecting rod is in an inclined state, and the position of the sliding block on the outer wall of the slide rail is adjusted after the connecting rod is pushed by the first crossbar.

[0007] As a further improvement to this technical solution, a support base is fixedly connected to the top of the support frame, and the bottom of the electric push rod is fixedly connected to the top of the support base.

[0008] As a further improvement to this technical solution, a rectangular block is fixedly connected to the top of the two baffles, and a side plate is symmetrically slidably connected to the outer wall of the rectangular block. A fixing rod is also symmetrically fixedly connected to the outer wall of the rectangular block and above the side plate. Multiple positioning holes are evenly opened inside the two fixing rods.

[0009] As a further improvement to this technical solution, the bottom ends of both side plates are located above the surface of the guide roller, and the side walls of the bottom ends of the two side plates are in contact with the side of the paper cup raw material conveyed by the guide roller.

[0010] As a further improvement to this technical solution, a rod is inserted into the positioning hole, and the bottom end of the rod is inserted into the inner wall of the top of the side plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this polylactic acid (PLA) coated paper cup production guiding mechanism, an auxiliary adjustment mechanism is set up to simultaneously lift the paper cup raw materials using two sets of sliding blocks and adjusting rollers. During the conveying of paper cup raw materials of different batches, thicknesses, and materials, a certain pressure is applied to change the tension, which can avoid wrinkles and loosening. This ensures that the paper cup raw materials remain horizontal and stable in the area below the coating machine body. Furthermore, during the coating process, accurate guidance can ensure that the PLA film is evenly covered on the paper surface, avoiding inconsistent film thickness and bubble defects, thus improving the coating effect and the final quality of the paper cup.

[0021] Example 1

[0022] Please see Figures 1-4As shown, this embodiment provides a polylactic acid (PLA) coated paper cup production guiding mechanism, including a support frame 1. A coating machine body 2 is fixedly connected to the top of the support frame 1. Two baffles 3 are also symmetrically fixedly connected to the top of the support frame 1. Multiple guide rollers 31 are evenly rotatably connected between the side walls of the two baffles 3. During PLA coated paper cup production, the paper cup raw material needs to be conveyed through the multiple guide rollers 31 to ensure that the paper cup raw material is coated below the coating machine body 2 before being conveyed to the next station. An auxiliary adjustment mechanism 4 is provided at the top of the support frame 1 and between the two baffles 3. The auxiliary adjustment mechanism 4 includes components symmetrically fixedly connected to the baffles 3. The slide rail 41 on the side wall of plate 3 has a sliding block 42 slidably connected to its outer wall. An adjusting roller 43 is rotatably connected between the side walls of the two sliding blocks 42. A connecting rod 44 is hinged to the bottom outer wall of each of the two sliding blocks 42. A first crossbar 45 is rotatably connected between the bottom side walls of the two connecting rods 44. An electric push rod 46 is installed above the top of the support frame 1. The extended end of the electric push rod 46 is fixedly connected to the outer wall of the first crossbar 45. The slide rail 41, sliding blocks 42, and adjusting roller 43 are symmetrically arranged in two sets. A second crossbar 51 is fixedly connected between the outer walls of the two sets of sliding blocks 42. The connecting rod 44 is in an inclined state and is subjected to the first crossbar 51. After the lever 45 is pushed, the position of the sliding block 42 on the outer wall of the slide rail 41 is adjusted. A support base 52 is fixedly connected to the top of the support frame 1. The bottom of the electric push rod 46 is fixedly connected to the top of the support base 52. The support base 52 can support and fix the electric push rod 46, ensuring the stability of the electric push rod 46 during use. By activating the electric push rod 46, the extended end of the electric push rod 46 pushes the first crossbar 45 towards one side. Since the connecting rod 44 is in an inclined state, and the connecting rod 44 is hinged to the sliding block 42 and the first crossbar 45, the sliding block 42 slides on the outer wall of the slide rail 41, thereby realizing... The connecting rod 44 pushes the sliding block 42 upward, and at the same time raises the height of the adjusting roller 43. Through the second crossbar 51, the two sets of sliding blocks 42 and adjusting roller 43 can simultaneously lift the paper cup raw material. During the conveying of paper cup raw materials of different batches, thicknesses and materials, a certain pressure is applied to change the tension, which can avoid wrinkles and loosening. This keeps the paper cup raw material horizontal and stable in the area below the coating machine body 2. In addition, during the coating process, accurate guidance can make the polylactic acid film evenly cover the paper surface, avoiding inconsistent film thickness and bubble defects, and improving the coating effect.

[0023] Two baffles 3 are fixedly connected to the top of rectangular blocks 61. Side plates 62 are symmetrically slidably connected to the outer walls of the rectangular blocks 61. Before the paper cup material is conveyed, the two side plates 62 are simultaneously controlled to slide on the outer walls of the rectangular blocks 61 according to the width of the paper cup material to be conveyed. This makes the distance between the two side plates 62 after adjustment match the width of the paper cup material, thereby limiting and guiding the paper cup material and facilitating its smooth conveying. Fixed rods 63 are also symmetrically fixedly connected to the outer walls of the rectangular blocks 61 and above the side plates 62. Multiple positioning holes 64 are evenly opened inside the two fixed rods 63. The bottom ends of the two side plates 62 are located above the surface of the guide rollers 31. The side walls of the bottom ends of the two side plates 62 are in contact with the side of the paper cup material conveyed by the guide rollers 31. A rod 71 is inserted into the positioning hole 64, with its bottom end engaging with the inner wall of the top of the side plate 62. By pulling the rod 71 out of the positioning hole 64 and separating its bottom end from the top of the side plate 62, the side plate 62 is released from its fixed position, making it easier to move and adjust its position. Once the side plate 62 is adjusted, the rod 71 is reinserted into the positioning hole 64, with its bottom end inserted into the inner wall of the top of the side plate 62, thus fixing the side plate 62. This ensures the side plate 62 remains stable during the paper cup raw material transport, guaranteeing accurate and stable transmission of the raw materials during production. This reduces production interruptions and equipment downtime caused by positional deviations or jamming, thereby improving production efficiency.
