Description
Technical Field
[0001] This utility model relates to the technical field of dust collection bag processing, and in particular to a composite shaping device for antistatic layer of container bags. Background Technology
[0002] The antistatic layer of a FIBC (Flexible Intermediate Bulk Container) is an important structure designed to prevent the generation and accumulation of static electricity, which is crucial for protecting the contents of the bag from static interference and damage. A composite shaping equipment for the antistatic layer of a FIBC is mainly used to composite the antistatic layer with the substrate during the production process of the FIBC, and to ensure the stability and durability of the antistatic layer through a shaping process. The composite FIBC material needs to be heated and shaped by a shaping mechanism, which typically includes a heating device and a shaping mold. Heating softens the material, and then the shape and size of the material are fixed by the shape of the shaping mold.
[0003] The existing Chinese utility model patent with application number CN202223443260.5 relates to a stretching and heat-setting device for polypropylene monofilaments in container bags, which includes a forming box, support legs, inlet, support roller, spray box, exhaust fan, telescopic spring and water valve, etc. It can heat the polypropylene monofilaments on both sides, resulting in better heating effect and ensuring product quality.
[0004] However, in actual use, the above-mentioned device does not have the ability to shape the electrostatic composite layer and the outer bag as a whole, nor does it have the ability to shape the bag in its unfolded state. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a composite shaping device for antistatic layers of FIBCs that uses a combing device to comb the inner layer of an opened FIBC, keeping the sides of the FIBC flat in the mold and reducing scratches on the inner side of the bag during the shaping process. An adsorption device adsorbs the outer side of the bag in the mold, allowing the outer side of the bag to adhere tightly to the mold. An auxiliary device limits the position of the mold and works with the mold to seal the area of action of the adsorption device, maintaining a negative pressure state inside the equipment to ensure that the bag remains adsorbed on the inner side of the mold. This improves the practicality of the device.
[0006] This utility model discloses a composite shaping device for the antistatic layer of a container bag; it includes a combing device, an adsorption device, and an auxiliary device. The adsorption device is installed on the combing device, and the auxiliary device is also installed on the combing device. The combing device combs the inner layer of the opened container bag, keeping the sides of the bag flat in the mold and reducing scratches on the inner side of the bag during the shaping process. The adsorption device adsorbs the outer side of the bag in the mold, ensuring that the outer side of the bag adheres tightly to the mold. The auxiliary device limits the position of the mold and works with the mold to seal the area of action of the adsorption device, maintaining a negative pressure state inside the equipment, thereby ensuring that the bag remains adsorbed on the inner side of the mold, improving the practicality of the device.
[0007] Preferably, the combing device includes a frame, a support platform, an electric cylinder, a support plate, a unfolding frame, and pressure rollers. The support platform is installed on the upper surface of the frame, and the electric cylinder is installed on the upper surface of the support platform. The moving end of the electric cylinder extends through the upper surface of the support platform to the lower side of the support platform and connects with the upper surface of the support plate. The unfolding frame is connected to the lower part of the support plate, and a set of pressure rollers is installed on each edge of the lower surface of the unfolding frame. By controlling the extension of the electric cylinder to drive multiple sets of pressure rollers to move downward, the inside of the bag is fully opened, and the multiple sets of pressure rollers reduce the possibility of the unfolding frame scratching the inner surface of the bag when it enters the bag, thus improving the practicality of the device.
[0008] Preferably, the device also includes a hot air blower and nozzles. The hot air blower is installed on the upper surface of the lower part of the unfolding frame, and multiple sets of nozzles are horizontally installed on the lower side of the unfolding frame. The output ends of the multiple sets of nozzles point to the pressure rollers they are close to. The output end of the hot air blower is connected to the multiple sets of nozzles. The hot air blows heated outside air through the hot air blower and then into the multiple sets of nozzles to heat the side of the pressure rollers. The hot air blows along the side of the pressure rollers towards the inner surface of the bag to heat the inner surface of the bag. Combined with the squeezing of the pressure rollers, this helps the bag to be shaped in the unfolded state, improving the practicality of the device.
[0009] Preferably, it also includes ventilation holes, with multiple sets of ventilation holes provided on the upper surface of the unfolding frame; through the multiple sets of ventilation holes provided on the upper surface of the unfolding frame, the airflow entering from the side during the process of the hot air fan drawing air in at the lower part of the bag is prevented from causing the bag to stick to the unfolding frame, thus improving the practicality of the device.
[0010] Preferably, the adsorption device includes a shaping chamber, a support ring, a shaping mold frame, a metal mesh, a filter plate, and a fan. The shaping chamber is located on the upper surface of the frame, and a support ring is located on the upper inner side of the shaping chamber. The upper part of the shaping mold frame can rest on the support ring, and the lower part of the shaping mold frame can enter the lower part of the shaping chamber. Metal mesh is installed on multiple sets of side and bottom surfaces of the shaping mold frame. A fan is installed on the side of the frame, and the fan's input end is located on the bottom surface inside the shaping chamber. A filter plate is installed on the fan's input end. The bag to be shaped is placed inside the shaping mold frame. The operator initially unfolds the bag's interior. For bags with handles, the handles are pressed against the underside of the shaping mold frame, and the handles are secured with the support rings. Then, the blower is turned on to extract the gas from the shaping chamber, causing the multiple sides and bottom of the bag to adhere to the corresponding metal meshes, thus automatically unfolding the bag's interior. Subsequently, multiple pressure rollers and a hot air blower on the combing device assist in shaping the sides of the bag, and the residual heat of the gas heats and shapes the entire bag. A filter plate prevents impurities from being sucked into the blower, improving the practicality of the device.
[0011] Preferably, the device also includes ventilation slots, quick connectors, and spring tubes. The bottom edge of the shaping mold frame has rounded chamfers, with multiple ventilation slots evenly distributed on the chamfers. Each set of ventilation slots on the chamfers is connected to a quick connector via an internal pipe. Four quick connectors are located on the lower end face of the shaping mold frame. A second set of fans is installed on the outer side of the frame. The input end of the second set of fans is connected to multiple quick connectors via multiple spring tubes. When the second set of fans is turned on, in conjunction with the quick connectors, spring tubes, and ventilation slots, the bottom edge of the bag is attracted, causing the bottom edge of the bag to heat up and form a rounded chamfer, thus providing the bag with a certain degree of support. The spring tubes allow the shaping mold frame to be directly pulled out from the shaping chamber during maintenance and replacement, and the connection between the spring tubes and quick connectors can then be disconnected, improving the practicality of the device and reducing the labor intensity of the operators.
[0012] Preferably, the auxiliary device includes a rotating limiting block and a sealing groove. Multiple sets of rotating limiting blocks are provided on the top inner side of the shaping chamber. Multiple sets of limiting grooves are provided on the top edge of the shaping mold frame corresponding to the positions of the multiple sets of rotating limiting blocks. A sealing groove is provided on the upper surface of the support ring, and a sealing gasket is placed in the sealing groove. The rotating limiting block limits the installation position of the shaping mold frame, preventing it from rotating during operation and colliding with the combing device, thus preventing equipment damage. The sealing strip in the sealing groove increases the sealing between the shaping mold frame and the support ring, thereby facilitating the maintenance of a negative pressure environment within the shaping chamber and improving the practicality of the device.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the combing device combs the inner layer of the opened container bag, so that the sides of the container bag are kept flat in the mold, reducing the scratches on the inner side of the bag during the shaping process; the adsorption device adsorbs the outer side of the bag in the mold, so that the outer side of the bag can stick tightly to the mold; the auxiliary device limits the position of the mold and works with the mold to seal the area of action of the adsorption device, maintaining a negative pressure state inside the equipment, thereby ensuring that the bag is kept adsorbed on the inner side of the mold, thus improving the practicality of the device.
