Description

Technical Field

[0001] The utility model relates to the field of baling machines, in particular to an adjusting mechanism of a baling machine. Background Art

[0002] The heat shrink film packaging machine is a device used by the logistics department to package various products ordered by customers. It has the advantages of fast packaging, high efficiency and convenience.

[0003] In the prior art, heat shrink film packaging machines are mostly composed of a conveyor belt, a film coating roller, a tensioning roller, a guide assembly, a correction assembly, a transverse heat sealing cutter, a longitudinal heat sealing cutter, an electric control assembly, a heat shrink furnace, etc. When in use, the film needs to be wrapped on the film coating roller, and the tensioning roller is used to support the pulled out film. When the article needs to be coated, the pulled out film is pushed by the article to make the film move in a transverse V shape. At this time, the coated film will be located at both ends of the article. The article is then placed on the conveyor belt, and the transverse heat sealing cutter and the longitudinal heat sealing cutter are used to heat seal and cut the end face and side edge of the film. Finally, the coated article is conveyed to the heat shrink furnace for heat shrinkage under the guidance of the guide assembly and the correction assembly. However, when the article lifts up the film and moves it on the conveyor belt, most of them are manually operated. During this process, the staff's arm will extend between the transverse heat sealing cutter and the longitudinal heat sealing cutter, which can easily cause accidental injury if not paid attention to, posing a safety hazard.

[0004] Therefore, it is necessary to invent a regulating mechanism of a baler. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0007] Based on the above features: the items to be wrapped are placed on the placement table, and then the motor can drive the roller to rotate. When the roller rotates, since the roller is connected to one end of the connecting shaft through the pulley and the belt strip, the connecting shaft will also rotate synchronously to drive the guide component to move back and forth. When the guide component moves forward, the guide component can push the item from the middle of the wrapping component to the upper end of the conveyor belt. During this process, the outer packaging film used for wrapping will cover the upper and lower ends of the item. Then the sealing and cutting component can perform side heat-seal shearing on the covered film, and can also perform end heat-seal shearing. Finally, the item will follow the conveyor belt to move into the heat shrink furnace to heat shrink the packaged film, and the cleaning component can clean its surface at the lower end of the conveyor belt.

[0008] Preferably, the cleaning assembly includes a base, a scraper is installed in the middle of the upper end of the base, lifting cylinders A are symmetrically installed on both sides of the upper end of the base, and a collection box is installed at the lower end of the base.

[0012] Preferably, the sealing and cutting assembly includes a transverse heat sealing cutter A and a transverse heat sealing cutter B arranged at the lower end of the transverse heat sealing cutter A, and longitudinal heat sealing cutter A and longitudinal heat sealing cutter B are symmetrically arranged on both sides of the transverse heat sealing cutter A and the transverse heat sealing cutter B, and the longitudinal heat sealing cutter A and the longitudinal heat sealing cutter B are aligned up and down.

[0013] Based on the above characteristics: the transverse heat sealing cutter A and the transverse heat sealing cutter B are aligned, and the end surface of the film wrapped on the surface of the object can be heat-sealed and cut, while the longitudinal heat sealing cutter A and the longitudinal heat sealing cutter B can heat-seal and cut both sides of the film, so that the surface of the object can be wrapped by the film.

[0014] Preferably, a support platform is installed in the middle of the rear end of the placement platform, and T-shaped sliding grooves are provided on the upper surfaces of the placement platform and the support platform.

[0015] Based on the above features: when the guide assembly is located at the upper end of the support table, the items can be placed on the upper end of the placement table. When the guide assembly moves forward to the upper end of the placement table, the items will be pushed away from the placement table and moved to the upper end of the conveyor belt.

[0018] Preferably, both sides of the guide push plate are in an open state, a semicircular gear is installed in the inner cavity of the guide push plate, and both ends of the semicircular gear are connected to the connecting shaft.

[0019] Based on the above characteristics: when the teeth on the surface of the semicircular gear rotate upward, the semicircular gear will engage with the upper convex teeth to push the guide push plate backward to the support table; when the teeth on the surface of the semicircular gear rotate downward, the semicircular gear will engage with the lower convex teeth to push the guide push plate forward, making it convenient for the forward-moving guide push plate to push the objects on the placement table to move.

[0020] The beneficial effects of the utility model are:

[0021] 1. It is convenient to automatically push the items after wrapping to the top of the conveyor belt. The rotation of the roller will drive the connecting shaft to rotate. At this time, the connecting shaft will drive the semicircular gear to rotate. When the teeth on the surface of the semicircular gear rotate to the top, the semicircular gear will mesh with the upper convex teeth to push the guide push plate to move backward to the support table. At this time, the items that need to be wrapped can be placed on the placement table. When the teeth on the surface of the semicircular gear rotate to the bottom, the semicircular gear will mesh with the lower convex teeth to push the guide push plate forward. At this time, the forward-moving guide push plate will push the items on the placement table to move, so that the items pass through the wrapping assembly and move to the top of the conveyor belt. There is no need for manual push and adjustment, which is simple and convenient.

[0022] 2. It is convenient to clean the surface of the conveyor belt. The scraper in the middle of the upper end of the base is always in contact with the lower end surface of the conveyor belt. When the conveyor belt rotates from top to bottom, the scraper can scrape and clean the surface of the conveyor belt that rotates to the bottom. The scraped waste will fall into the collection box for collection.

[0023] 3. The lifting cylinder A is connected to the lower end of one side of the longitudinal heat-sealing cutter B, the other side of the longitudinal heat-sealing cutter B is connected to the two sides of the transverse heat-sealing cutter B, and the lower end of the lifting cylinder B is connected to the other side of the transverse heat-sealing cutter B. When the lifting cylinder A and the lifting cylinder B are started, the lifting cylinder A and the lifting cylinder B can synchronously push the longitudinal heat-sealing cutter B and the transverse heat-sealing cutter B upward from both ends, so that the longitudinal heat-sealing cutter B and the transverse heat-sealing cutter B can heat-seal and cut the end surface and side surface of the wrapping film at the same time.
