Description

Technical Field

[0001] The utility model relates to the technical field of film blowing devices, in particular to a film blowing device for preparing a degradable shopping bag. Background Art

[0002] The production line for producing degradable shopping bags consists of main equipment such as film blowing machines, printing machines, and bag making machines. The film blowing machine plasticizes the degradable raw materials, cools the generated blown film into shape, and rolls it up using a reel to facilitate subsequent printing on its surface through printing equipment, etc. Finally, the printed film material is bottom-sealed and cut by the bag making machine, which basically completes the production of plastic bags.

[0003] After a long period of use in the production process of the current film blowing machine, a layer of dust will adhere to the inner wall of the material feed port, so it is often necessary to clean it manually. Before cleaning, the operator is generally required to seal the feed port first to prevent dust from falling into the equipment during the cleaning process. This cleaning method is more troublesome. At the same time, when the equipment is not in use, dust is easy to fall into the equipment through the feed port, resulting in the inability to fundamentally solve the problem, thereby affecting the production quality of later products.

[0004] Therefore, a film blowing device for preparing a degradable shopping bag is proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a film blowing device for preparing a degradable shopping bag, comprising a feed plate 1; a guide plate 2 is installed on the lower surface of the feed plate 1, a discharge metering device 3 is installed on the lower surface of the guide plate 2, a heating cylinder 4 is installed below the outer wall of the discharge metering device 3, a film material extrusion device 5 is installed on the right side of the outer wall of the heating cylinder 4, a rotating shaft 6 is rotatably installed on the left and right sides of the inner wall of the guide plate 2, a meshing plate 7 is installed on the shaft wall of the two rotating shafts 6, a connecting shaft 8 is installed on the front end of the two rotating shafts 6, and the front ends of the two connecting shafts 8 penetrate the guide plate 2 and a driving auxiliary wheel 9 is installed on the front side of the inner wall, and a transmission assembly is arranged on the front side surface of the guide plate 2. The motor 10 in the rotating assembly drives the driving auxiliary wheel 11 to rotate, thereby driving the driving auxiliary wheels 9 and the driven wheels 13 on both sides to rotate together, and driving the rotating shafts 6 and the meshing plates 7 on both sides to rotate in relative or opposite directions, so as to realize the sealing of the inside of the feed port, and facilitate the problem of dust falling into the inside of the equipment during the cleaning process of the inner wall of the feed port. At the same time, the feed port is sealed when the equipment is stopped, so as to prevent the entry of dust and improve the production quality of the product.

[0023] like Figure 3 and 4As shown, in order to prevent dust from entering the interior of the equipment when the equipment is shut down and to prevent it from affecting the next use of the equipment, the transmission assembly includes two fixed shafts 12, the rear ends of the two fixed shafts 12 are fixed to the front surface of the guide plate 2, and the front ends of the two fixed shafts 12 are rotatably installed with driven wheels 13, one side of the outer wall of the two driven wheels 13 is meshed with one side of the outer wall of the corresponding active secondary wheel 9 through convex teeth, a motor 10 is installed on the front surface of the feed plate 1, and a driving wheel 11 is installed on the output end of the motor 10, one side of the outer wall of the driving wheel 11 is meshed with one side of the outer wall of the left active secondary wheel 9 through biting teeth, and the driving wheel 11 is driven to rotate by controlling the motor 10, thereby driving the active secondary wheels 9 and the driven wheels 13 on both sides to rotate together, and driving the rotating shafts 6 and the meshing plates 7 on both sides to rotate in relative or opposite directions, thereby realizing the closure of the inside of the feed port.
