Description

Technical Field

[0001] This invention relates to the technical field of cleaning devices, and more specifically to a cleaning device for a heat-sealing machine for storage bags. Background Technology

[0002] In the industrial production of storage bags, the heat-sealing machine is the core equipment for achieving bag sealing. It heats and melts the plastic edges of the storage bag using a heat-sealing plate and applies pressure to achieve a sealing effect. However, during continuous heat-sealing operations, the hot-melt plastic at the edges of the storage bag easily adheres to the surface of the heat-sealing plate, forming stubborn residual impurities.

[0003] In existing technologies, the cleaning of impurities on heat-sealing plates is mostly done manually. Operators need to use tools such as scrapers and rags to manually scrape the heat-sealing plates, which is not only labor-intensive and inefficient, but also prone to scratching the heating surface of the heat-sealing plates due to improper operation, resulting in uneven heating of the heat-sealing plates and affecting the heat-sealing quality of subsequent storage bags. In addition, the scrapers themselves are prone to adhering to impurities during the cleaning process, requiring frequent disassembly and cleaning, which further reduces the continuity of production. Summary of the Invention

[0006] Preferably, the scraping assembly includes a slide bar, a movable frame, and elastic scrapers. Each heat-sealing plate has a slide bar connected to its upper side via a fixed plate. The two sides of the movable frame are slidably connected to the two slide bars via sliders. Two elastic scrapers are provided and symmetrically arranged on both sides of the movable frame.

[0007] Preferably, the vibration assembly includes a vibration rod, a spring, and a vibrating hammer. The vibration rod is slidably connected to a fixed frame on the side of one of the sliders, and a ball bearing is rolledly connected to one end of the rod near the slider. The spring is sleeved on the vibration rod and located between the baffle on the vibration rod and the fixed frame. The slider has several arc-shaped grooves evenly distributed on it for driving the vibration rod to move. The vibration rod is provided with a rack that is slidably connected to the side of the moving frame. Two vibrating hammers are provided and symmetrically arranged on both sides of the moving frame and are rotatably connected to the moving frame through a rotating shaft. Each vibrating hammer is provided with a fan-shaped toothed ring that meshes with the rack.

[0008] Preferably, the overall shape of the fixed plate is 'L' shaped structure.

[0009] Preferably, the top of the moving frame is provided with a handle.

[0013] Preferably, the overall shape of the fixed frame is 'N' shaped structure.

[0014] The present application has the following beneficial effects: The present application can efficiently scrape off the hot melt residual impurities on the heat sealing plate during the movement process by adopting the elastic scrapers in close contact with the inner side of the heat sealing plate, and by means of elastic deformation to ensure the overall adhesion of the scrapers and the surface of the heat sealing plate, thereby avoiding the problem of uneven heat sealing caused by the accumulation of impurities. At the same time, the vibration assembly generates vibration by the periodic knocking of the vibrating hammer on the elastic scraper, which can timely shake off the impurities attached to the scraper, prevent the secondary pollution of the heat sealing plate by the scraper, and further improve the cleaning effect.
