Description

Technical Field

[0001] The utility model relates to the technical field of biodegradable bag production, in particular to a film blowing machine for biodegradable bag production. Background Art

[0002] Degradable bags refer to bags that can automatically decompose into substances such as carbon dioxide and water in the natural environment. Usually, during the production process, a film blowing machine is required to heat-melt the material and form molten plastic. Then, an air nozzle is used to fill gas into the cylindrical plastic film. The artificially molten plastic moves on the suspension and passes through the air ring, pressure roller, traction roller, and herringbone plywood in sequence before being wound up.

[0003] According to the "A film blowing machine for producing degradable bags" with Chinese patent publication number CN219028476U, it mainly describes that by installing a clamping head, a first filter screen and a pull plate, the first filter screen is easily removed and cleaned, and the heat dissipation and wind cleanliness effect of the blowing component is improved. The function of the clamping rod is to facilitate the fixation of the support plate. Pulling the clamping rod makes it move out of the first opening and the second opening. Pulling the pull plate drives the support plate to move. The movement of the support plate drives the movement of the first filter screen. The movement of the first filter screen drives the clamping head to move. The movement of the clamping head moves it out of the clamping port, so that the first filter screen is easily removed and cleaned, and the heat dissipation and wind cleanliness of the blowing component are improved. The function of facilitating the removal and cleaning of the first filter screen and improving the heat dissipation and wind cleanliness of the blowing component is achieved. In the process of producing degradable bags, multiple people are required to take turns to hold the molten plastic and move it up, which is more troublesome. It passes through multiple devices in sequence and then to the winding roller, which makes the film blowing machine somewhat troublesome when producing degradable bags.

[0004] Therefore, a film blowing machine for the production of biodegradable bags is proposed to solve the problem that in the process of producing biodegradable bags, multiple people are required to take turns to move the molten plastic upward, which is quite troublesome and passes through multiple devices in sequence and then to the winding roller, making the film blowing machine somewhat troublesome in producing biodegradable bags.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1-3The film blowing machine for producing biodegradable bags shown in the figure includes a fixed plate 1, a film blowing body 2 and a connecting frame 3. The upper end of the connecting frame 3 is fixedly connected to a driving motor and the output end of the driving motor is fixedly connected to a first screw 4. The driving motor on the connecting frame 3 can drive the first screw 4 to rotate and make the movable plate 5 move up and down. At this time, the movable plate 5 can drive the movable frame 9 to be in a lower position, so that the hot-melt material is extruded from the film blowing body 2. At this time, a single person can manually pull the hot-melt plastic upward, pass through the gap relative to the movable frame 9, and pass between multiple pressure rollers 14, which greatly improves the speed of biodegradable bag production. The first screw 4 is threadedly connected to the movable plate 5. A first groove 6 is opened on one side of the movable plate 5. The first groove 6 corresponds to the film blowing body 2. An air ring 7 is fixedly connected in the first groove 6. The air ring 7 provides a cooling effect during the production of biodegradable bags. The movable plate 5 is located on the four sides of the upper end of the first groove 6 Both are fixedly connected with a second screw 8, and a relatively arranged moving frame 9 is sleeved on the second screw 8. Rotating the adjusting ring 17 can make the moving frame 9 move up and down, and increase the distance between the upper and lower moving frames 9. A connecting roller 10 is provided on the opposite side of the two moving frames 9. The moving plate 5 is fixedly connected to the side away from the first groove 6 with two connecting plates 11, and the upper and lower sides of the connecting plate 11 are fixedly connected with vertical rods 12. A support plate 13 is fixedly connected between the two adjacent vertical rods 12. Two pressure rollers 14 are rotatably connected to the support plate 13, and the diameter of the pressure roller 14 increases from top to bottom. The moving plate 5 is located between the two support plates 13 and is provided with a second groove 15. A winding roller 16 is provided on the side of the fixed plate 1 away from the film blowing machine body 2. The winding roller 16 consists of a connecting plate, a click and a roller body, which can pull the plastic bag body to move, and the winding roller 16 corresponds to the second groove 15.

[0018] Among them, the protrusions are evenly fixedly connected to the four sides of the bottom end of the adjustment ring 17, the movable frame 9 contacts the upper side of the adjustment ring 17, and the adjustment ring 17 is threadedly connected to the second screw 8. By setting the adjustment ring 17, the movable frame 9 can be moved up and down by rotating the adjustment ring 17, and the distance between the upper and lower movable frames 9 can be increased.

[0019] Among them, the connecting roller 10 is rotatably connected to the first slider 19, and the first slider 19 is threaded with an adjusting rod 18. The adjusting rod 18 is rotatably connected to the groove. The groove is located on both sides of the movable frame 9. By setting the adjusting rod 18, the two opposite connecting rollers 10 can be moved relative to each other to adapt to the diameter of the degradation bag tube.

[0020] Among them, the degradation bag is moved out from between the two pressure rollers 14 on the lowest side, and passes around the bottom side of one of the elastic rollers 22, and then passes around the upper side of the other elastic roller 22, and is finally rolled up by the winding roller 16. The elastic roller 22 rotates to connect to the second slider 21, and the second slider 21 is sleeved on both sides of the support block 20. The support block 20 is fixedly connected in the groove, and the groove is located on the connecting plate 11. By setting the elastic roller 22, it can provide pulling when the winding roller 16 rolls up the degradation bag, thereby improving the winding effect of the winding roller 16.

[0021] Among them, the two second sliders 21 are in contact with both sides of the spring 23, and the spring 23 is sleeved on the support block 20. By setting the spring 23, the stress between the two elastic rollers 22 is increased, and the winding effect of the winding roller 16 is improved.

[0022] Working principle: start the driving motor on the upper side of the connecting frame 3 and drive the first screw 4 to rotate. At this time, the movable plate 5 moves to the bottom side of the movable plate 5 and contacts the upper side of the film blowing machine body 2, and then adjust the upper and lower moving frames 9 to be at a suitable spacing, and control the adjusting rod 18 to make the first slider 19 move. At this time, the distance between the two adjacent connecting rollers 10 is adjusted to a suitable spacing, the film blowing machine 2 hot melts and extrudes the material, and forms hot melt plastic on the upper side of the film blowing machine body 2. Then a single person manually pulls the hot melt plastic and passes through the air ring 7, and then passes between multiple adjacent two moving frames 9, and then passes through the limit between the pressure rollers 14, gradually becoming thinner, and then moves out from between the two pressure rollers 14 on the lowest side, and bypasses from the bottom side of one of the elastic rollers 22, and then bypasses from the upper side of the other elastic roller 22, and is finally wound up by the winding roller 16. At this time, the driving motor on the connecting frame 3 reverses and drives the first screw 4 to rotate. At this time, the movable plate 5 moves up and increases the spacing of the degradation bag tube extension, thereby reducing the operation time.
