Technical Field

[0001] The utility model belongs to the technical field of heat setting of polypropylene woven bags, and particularly relates to a heat setting device for producing polypropylene woven bags. Background Technique

[0002] A woven bag, also known as a snake skin bag, is a kind of plastic bag used for packaging. Its raw materials are generally various plastic raw materials such as polyethylene and polypropylene. When producing and processing polypropylene woven bags, a heat setting device is often needed to shape the woven bags. For example, the patent number is 202321979242.0, and the patent name is a heat setting device for producing polypropylene woven bags, which includes a bottom plate. Both sides of the top of the bottom plate are fixedly connected with lifting devices. By setting the lifting devices, it is convenient to adjust the height position of the whole device. Under the action of the moving placement device, it is convenient to take and place the woven bags.

[0003] However, during the use of the above scheme, after shaping, the temperature of the woven bag is relatively high. Although the placement frame can be removed, it is inconvenient to take out the woven bag in the placement frame, and after shaping, the polypropylene woven bag may adhere and adsorb on the surface of the placement frame. Content of the Utility Model

[0004] To solve the problems existing in the prior art, the utility model provides a heat setting device for producing polypropylene woven bags. Through the setting of a blower, the generated wind is blown out through the air outlet nozzle to dissipate heat and cool the polypropylene woven bag on the placement plate, facilitating taking. Through the setting of a motor, the motor can drive a screw rod to rotate. The rotation of the screw rod drives the movement of a scraper threadedly connected to the surface. Through the movement of the scraper and the inclined plate, the polypropylene woven bag is scraped off, preventing the polypropylene woven bag from adsorbing on the surface of the placement plate and facilitating the removal of the polypropylene woven bag.

[0005] To achieve the above object, the present utility model provides the following technical solution: A heat setting device for the production of polypropylene woven bags, including a bottom plate, two fixed boxes are fixedly connected to the top end of the bottom plate, a fixed plate is slidably connected inside the fixed box, support plates are fixedly connected to the top ends of the two fixed plates, a fixed frame is fixedly connected to the surface of the support plate, a cylinder is provided at the top end of the fixed frame, and the cylinder fixedly penetrates the fixed frame, a heating plate is provided at the output end of the cylinder, an electric slide rail is provided at the top end of the support plate, a slider is slidably connected inside the electric slide rail, a clamping block is clamped inside the slider, one end of the clamping block away from the slider is fixedly connected to a placement frame, a motor is fixedly connected to one end of the placement frame, a screw rod is fixedly connected to the output shaft of the motor, a scraping plate is threadedly connected to the surface of the screw rod, a rectangular groove is opened at one end of the placement frame corresponding to the position of the motor, the scraping plate movably penetrates the rectangular groove, a sliding groove is opened on the surface of the placement frame, one end of the scraping plate away from the screw rod is slidably connected to the inside of the sliding groove, inclined plates are fixedly connected to both ends of the scraping plate, and a blower is provided at one end of the support plate.

[0006] Further, an air outlet nozzle is provided at one end of the blower, and the inside of the air outlet nozzle is communicated with the inside of the blower.

[0007] Further, an electric hydraulic push rod is fixedly connected to the top end of the bottom plate, and one end of the electric hydraulic push rod away from the bottom plate is fixedly connected to the bottom end of the support plate.

[0019] Working principle: When in use, place the polypropylene woven bag to be thermoformed inside the placement frame 11, then start the electric slide rail 8 to drive the slider 9 to move. The slider 9 drives the clamping block 10 to move, and the clamping block 10 drives the placement frame 11 to move, so as to move the polypropylene woven bag directly below the heating plate 7. Through the setting of the cylinder 6, the heating plate 7 can be driven to move. After being powered on, the heating plate 7 contacts the polypropylene woven bag and heats and shapes it. After thermoforming, the cylinder 6 drives the heating plate 7 to reset. Then, through the cooperation of the electric slide rail 8, the slider 9 and the clamping block 10, the placement frame 11 is driven to move in the direction of the blower 17. Through the setting of the blower 17, the generated wind blows out through the air outlet nozzle to dissipate heat and cool the polypropylene woven bag on the placement plate for easy taking. At the same time, the placement frame 11 is clamped inside the chute 15 through the clamping block 10 and can be taken down separately. Through the setting of the motor 12, the screw rod 13 can be driven to rotate. The rotation of the screw rod 13 drives the scraper 14 with a threaded connection on its surface to move. Through the movement of the scraper 14 and the inclined plate 16, the polypropylene woven bag is scraped off to prevent the polypropylene woven bag from sticking and adsorbing on the surface of the placement plate, facilitating the removal of the polypropylene woven bag. Through the setting of the electric hydraulic push rod, the support plate 4 can be driven to move to adjust the height of the support plate 4 for easy use.
