Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic packaging machines, and specifically relates to a feeding device for a paper-plastic packaging machine. Background Technique

[0002] A paper-plastic packaging machine is a machine that uses paper-plastic made of renewable plant fibers to complete the encapsulation of products through heating. Paper-plastic packaging machines are widely used in the fields of medicine, food, hardware, textiles, and dyes in daily life, and are usually used for the secondary packaging of paper packaging.

[0003] The paper-plastic used in paper-plastic packaging machines is usually used in rolls. The paper-plastic is released by rotating the paper-plastic roller to complete the feeding of the packaging machine. However, most paper-plastic packaging machines on the market usually lack a device for protecting the paper-plastic, which is likely to cause dust to float on the paper-plastic during the workshop production process. Especially for paper-plastic packaging machines used in the fields of medicine and food, if the paper-plastic with residual dust is encapsulated, it will not only affect the appearance of the product but also pose a safety hazard. Summary of the Invention

[0004] The purpose of the utility model is to provide a feeding device for a paper-plastic packaging machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A feeding device for a paper-plastic packaging machine, including a fixing plate.

Specific embodiments

[0022] As Figures 1-4 shown, the present utility model provides a technical solution: a feeding device of a paper-plastic packaging machine, including a fixed plate 1, a connecting block 2 is fixedly installed on the side wall of the fixed plate 1, a connecting plate 3 is fixedly installed on the side wall of the fixed plate 1, a bolt 4 is threadedly connected to the inner wall of the fixed plate 1, and the fixed plate 1 can be installed on the packaging machine by using the bolt 4. A support rod 5 is fixedly installed on the side wall of the fixed plate 1, and the paper-plastic roller can be supported by using the support rod 5. A limiting groove 6 is opened on the support rod 5, and the paper-plastic roller can be limited by using the limiting groove 6. A protection mechanism 7 for protecting the paper-plastic is arranged on the fixed plate 1. By arranging the protection mechanism 7, dust can be prevented from adhering to the surface of the paper-plastic. A cleaning mechanism 8 for cleaning the paper-plastic is arranged on the protection mechanism 7. By arranging the cleaning mechanism 8, the upper and lower surfaces of the paper-plastic can be cleaned to fully ensure that the paper-plastic is encapsulated for the product in a dust-free state.

[0023] The above protection mechanism 7 includes a baffle 71, a protective cover 72, a connecting rod 73, a torsion spring 74, a through groove 75, and a handle 76; the baffle 71 is hinged on the side wall of the connecting block 2, and a through groove 75 is opened on the baffle 71. A roll of paper-plastic roller is placed inside the limiting groove 6, and then the paper-plastic on the paper-plastic roller is passed through the through groove 75 and guided to the packaging machine. A handle 76 is fixedly installed on the top of the baffle 71. The baffle 71 can be pulled upward by using the handle 76, so that the baffle 71 rotates upward and compresses the torsion spring 74. A torsion spring 74 is arranged at the hinge of the baffle 71 and the connecting block 2. When the handle 76 is released, the baffle 71 can be driven to rotate downward and reset by the elasticity of the torsion spring 74. The protective cover 72 is hinged on the side wall of the connecting plate 3. One end of the connecting rod 73 is hinged on the side wall of the baffle 71, and the other end of the connecting rod 73 is hinged on the side wall of the protective cover 72. When the baffle 71 rotates upward, it will squeeze the connecting rod 73 downward, so that the connecting rod 73 squeezes the protective cover 72 downward, and thus the protective cover 72 can be rotated downward.

[0024] The above-mentioned cleaning mechanism 8 includes a handle 81, a limit block 82, a first sponge 83, a second sponge 84, and a spring 85; both ends of the handle 81 penetrate through the baffle 71 and are fixedly installed with the limit block 82, and the handle 81 is slidably connected to the penetration part of the baffle 71. The outer wall of the handle 81 is sleeved with the spring 85. One end of the spring 85 is fixedly installed on the outer wall of the limit block 82, and the other end of the spring 85 is fixedly installed at the bottom of the baffle 71. Release the handle 81. At this time, the elastic force of the limit block 82 and the spring 85 can drive the handle 81 to move downward and reset. The first sponge 83 is fixedly installed on the lower surface of the handle 81. Pull the handle 81 upward to drive the separation of the first sponge 83 and the second sponge 84. At this time, pass the paper-plastic through the gap between the first sponge 83 and the second sponge 84 and guide it to the packaging machine. The second sponge 84 is fixedly installed at the top of the baffle 71, and the second sponge 84 is attached to the bottom of the first sponge 83. When the packaging machine pulls the paper-plastic during operation, the first sponge 83 and the second sponge 84 can be used to clean the upper and lower surfaces of the paper-plastic, fully ensuring that the paper-plastic encapsulates the product in a dust-free state.

[0025] Working principle: First, install the fixed plate 1 on the packaging machine through the bolt 4, and then pull the baffle 71 upward through the handle 76, so that the baffle 71 rotates upward and compresses the torsion spring 74. At the same time, the baffle 71 will squeeze the connecting rod 73 downward, so that the connecting rod 73 squeezes the protective cover 72 downward, so that the protective cover 72 can rotate downward. By rotating the baffle 71 upward and the protective cover 72 downward, the support rod 5 on the side wall of the fixed plate 1 can be exposed. Then place a roll of paper-plastic roller inside the limit groove 6, and pass the paper-plastic on the paper-plastic roller through the through groove 75. Then release the handle 76. The elastic force of the torsion spring 74 can drive the baffle 71 to rotate downward and reset. At the same time, the baffle 71 will pull the connecting rod 73 upward, so that the connecting rod 73 pulls the protective cover 72 upward, making the protective cover 72 rotate upward and fit together with the baffle 71. At this time, the closed space formed by the baffle 71 and the protective cover 72 can protect the paper-plastic on the support rod 5, preventing dust from adhering to the paper-plastic and affecting the encapsulation of the paper-plastic to the product.

[0026] After the paper-plastic on the support rod 5 is pulled outwards through the through groove 75, the handle 81 is pulled upwards, so that the handle 81 drives the limit block 82 to move upwards, the limit block 82 compresses the spring 85, and at the same time the handle 81 can drive the first sponge 83 to separate from the second sponge 84. At this time, the paper-plastic is passed through the gap between the first sponge 83 and the second sponge 84 and guided to the packaging machine. Then the handle 81 is released. At this time, the elastic force of the limit block 82 cooperating with the spring 85 can drive the handle 81 to move downwards and reset, so that the first sponge 83 at the bottom of the handle 81 and the second sponge 84 at the top of the protective cover 72 respectively clamp the upper and lower surfaces of the paper-plastic. When the packaging machine pulls the paper-plastic during operation, the paper-plastic roller in the limit groove 6 will rotate and release the paper-plastic outwards through the through groove 75. At this time, the first sponge 83 cooperating with the second sponge 84 can clean the upper and lower surfaces of the paper-plastic, fully ensuring that the paper-plastic packages the product in a dust-free state.

[0027] The above has generally described the present invention in detail, but on the basis of the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
