Description

Technical Field

[0001] This utility model relates to the field of plastic sealing and cutting machine technology, specifically a horizontal sealing servo electric cylinder hot pressing device. Background Technology

[0002] Plastic film is a thin film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products are taking up an increasingly larger share of the market, especially composite plastic flexible packaging, which is widely used in the food, pharmaceutical, and chemical industries. Food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, retortable food packaging, and fast food packaging. These products have brought great convenience to people's lives. Plastic film needs to be cut when it is rolled to a sufficient length.

[0003] Our company's patent document number CN221938695U discloses a liftable pneumatic tool holder device, which includes an upper tool holder, a lower tool holder, and a base. The upper tool holder is fixed to the lower support seat by adjusting bolts, and the lower tool holder is located directly below the upper tool holder. A pneumatic linkage lifting mechanism and symmetrically arranged linear rails on both sides are provided between the lower support seat and the lower tool holder. The extension and retraction of the cylinder drives the lower tool holder to move up and down along the direction of the linear rails.

[0004] However, this mechanism has the following problems: First, the structure is relatively complex, requiring the use of compression springs and linkage mechanisms to separate and fit the upper and lower tool holders, resulting in high production and manufacturing costs; Second, the installation and maintenance efficiency is low, as components such as compression springs need to be removed if a malfunction occurs, and they need to be reinstalled after repair, making the process cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide a horizontal sealing servo electric cylinder hot pressing device to solve the problems existing in the above-mentioned background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a horizontal sealing servo electric cylinder hot pressing device, comprising a base 1, a movable support 8, an upper knife holder 12, and a lower knife holder 16. The movable support 8 is connected to the base 1 via a transverse linear rail slider assembly 17. Heating plates 11 are fixed on both the upper knife holder 12 and the lower knife holder 16. The upper knife holder 12 and the lower knife holder 16 are simultaneously connected to the longitudinal linear rail slider assemblies 10 on both sides of the movable support 8 via U-shaped connecting plates 9. A servo electric cylinder 13 is provided at the top of the movable support 8, and the output end of the servo electric cylinder 13 is connected and fixed to the upper knife holder 12 via a connecting flange 14. Two cylinders 7 are provided at the bottom of the movable support 8, and the output ends of the cylinders 7 are fixedly connected to the lower knife holder 16.

[0007] Furthermore, a connecting plate 6 is fixed on one side of the movable support 8, and a servo motor 5 and a passive gear 3 are arranged in sequence below the connecting plate 6. An active gear 4 that meshes with the passive gear 3 is fixed at the output end of the servo motor 5. A rack 2 is arranged below the passive gear 3 and is fixed on the base 1.

[0008] Furthermore, there are four longitudinal linear guide slider assemblies 10 in total, with two in a group. The longitudinal linear guide slider assemblies 10 in the same group are arranged opposite each other and connected to the U-shaped connecting plate 9. The two groups of longitudinal linear guide slider assemblies 10 are symmetrically arranged on both sides of the movable bracket 8.

[0009] Compared with the prior art, the beneficial effects of this utility model are: first, the use of servo electric cylinders and linear guide assemblies to replace the original guide columns and compression springs greatly reduces unnecessary parts and saves production costs; second, the structure is simpler and maintenance is more convenient. If there is a problem with the parts or electrical components, they can be replaced directly without disassembling other things, which improves the efficiency of maintenance and subsequent upkeep.
