Description

Technical Field

[0001] The utility model relates to the field of production equipment, in particular to a scissors arm pinch roll device. Background Art

[0002] With the rapid development of solventless composite adhesives, processes, and equipment, the application fields of solventless composite are becoming wider and wider.

[0003] Cigarette packaging boxes are mainly used to protect cigarette sticks and facilitate the storage and transportation of cigarettes. Currently, the papers used for making cigarette packaging boxes are mainly white cardboard for hard packs and coated paper for soft packs. These papers are all high-grade packaging papers. To increase the decoration and anti-counterfeiting properties of cigarette packaging boxes, transfer cardboard obtained by laminating white cardboard or coated paper with a transfer film and then peeling off the base film is usually used as the material for making the box body.

[0004] In a traditional coating laminating machine, the upper pressure roll is pressed down by a cylinder, and the lower pressure roll is a passive roll that remains stationary. Therefore, during roll pressing, the roll pressure between the upper and lower pressure rolls is poor, which is not conducive to the roll pressing of the material film. Therefore, improvements are still needed. Content of the Utility Model

[0005] The utility model provides a scissors arm pinch roll device to solve the above-mentioned problems. The device includes an upper swing arm and a lower swing arm. The upper swing arm is arranged above the lower swing arm. An upper rotating shaft is arranged at a position near the rear end of the upper swing arm. An upper pinch roll is arranged at the front end of the upper swing arm. A cylinder is connected and arranged at a position above the front end of the upper swing arm. A lower rotating shaft is arranged at a position near the rear end of the lower swing arm. A lower pinch roll is arranged at the front end of the lower swing arm. A connecting rod is arranged between the lower swing arm and the upper swing arm. Two ends of the connecting rod are respectively connected to the rear end of the upper swing arm and the rear end of the lower swing arm.

[0006] Preferably, an upper limit block is arranged at a position above the rear end of the upper swing arm.

[0007] Preferably, a lower limit block is arranged at a position below the front end of the lower swing arm.

[0008] The beneficial effects of the utility model are as follows: The structure of the utility model is reasonably designed and easy to use. The upper swing arm, the lower swing arm, and the connecting rod cooperate to form a scissors arm, so that the upper pinch roll and the lower pinch roll can be synchronously pulled under the drive of the cylinder, making the roll pressure between the upper pinch roll and the lower pinch roll better. At the same time, the synchronous drive of the upper pinch roll and the lower pinch roll can also save production costs and make the roll pressing of the pinch rolls more convenient and efficient. Description of the Drawings

[0009] The utility model will be described by way of examples with reference to the accompanying drawings, where:

[0010] Figure 1 is the overall structural schematic diagram of the present utility model;

[0011] In the figure: 1, upper swing arm; 2, upper limit block; 3, upper rotating shaft; 4, connecting rod; 5, lower rotating shaft; 6, lower swing arm; 7, lower limit block; 8, lower pinch roller; 9, upper pinch roller; 10, cylinder. Specific embodiments

[0012] All features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0013] Any feature of this specification, unless specifically described, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically described, each feature is only an example in a series of equivalent or similar features.

[0014] As Figure 1 shown, a scissor arm pinch roller device includes an upper swing arm 1 and a lower swing arm 6. The upper swing arm 1 is arranged above the lower swing arm 6. An upper rotating shaft 3 is arranged at a position near the rear end of the upper swing arm 1. An upper pinch roller 9 is arranged at the front end of the upper swing arm 1. A cylinder 10 is connected and arranged at a position above the front end of the upper swing arm 1. A lower rotating shaft 5 is arranged at a position near the rear end of the lower swing arm 6. A lower pinch roller 8 is arranged at the front end of the lower swing arm 6. A connecting rod 4 is arranged between the lower swing arm 6 and the upper swing arm 1. Two ends of the connecting rod 4 are respectively connected to the rear end of the upper swing arm 1 and the rear end of the lower swing arm 6.

[0015] An upper limit block 2 is arranged at a position above the rear end of the upper swing arm 1.

[0016] A lower limit block 7 is arranged at a position below the front end of the lower swing arm 6.

[0017] The upper swing arm 1 is installed on a fixed frame through the upper rotating shaft 3, and the lower swing arm 6 is installed on the fixed frame through the lower rotating shaft 5; the cylinder 10, the upper limit block 2, and the lower limit block 7 are all installed on the fixed frame.

[0018] During the use process, when it is necessary to clamp and roll a material film by a coating laminator, the upper swing arm 1 can be pulled upward by the cylinder 10, so that the upper swing arm 1 rotates upward with the upper rotating shaft 3 as a fulcrum. Since the lower swing arm 6 is connected to the upper swing arm 1 through the connecting rod 4, when the upper swing arm 1 rotates upward, the lower swing arm 6 will also be driven to rotate upward with the lower rotating shaft 5 as a fulcrum, so that the lower pinch roller 8 closely adheres to the bottom of the upper pinch roller 9, thereby enabling the material film passing through the upper pinch roller 9 and the lower pinch roller 8 to be well rolled.

[0019] The beneficial effects of the present utility model are as follows: The present utility model has a reasonable structural design and is convenient to use. The upper swing arm, the lower swing arm and the connecting rod cooperate to form a scissor arm, so that the upper pinch roller and the lower pinch roller can be synchronously pulled under the drive of the air cylinder, making the roll pressure between the upper pinch roller and the lower pinch roller better. At the same time, the synchronous drive of the upper pinch roller and the lower pinch roller can also save production costs and make the roll pressing of the pinch rollers more convenient and efficient.

[0020] The present utility model is not limited to the foregoing specific embodiments. The present utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
