Description

Technical Field

[0001] This utility model relates to the technical field of packaging film manufacturing equipment, specifically to a PLA bio-based biodegradable packaging film manufacturing equipment. Background Technology

[0002] PLA biodegradable packaging film is a biodegradable film made primarily of polylactic acid (PLA). It is completely biodegradable. PLA is made from renewable plants such as corn and sugarcane through processes such as fermentation and polymerization. It is a bio-based material and is widely used in transportation and protective packaging in industries such as food, pharmaceuticals, textiles, building materials, chemicals, and cables.

[0003] As disclosed in CN113386333B, a high-barrier film manufacturing equipment for pharmaceutical packaging includes a die head, a frame, and a controller. The die head is located below the frame. A single-screw extruder is installed on the outer wall of the die head, and a roller is provided at the upper end of the die head. One end of the roller is fixedly connected to a motor, and a steel wire is provided between the roller and the die head. One end of the steel wire is fixedly connected to the roller, and a sleeve is installed at the other end. A clamping module is installed at the upper end of the sleeve, and a straight plate is provided between the sleeve and the roller.

[0004] Although the sleeve design allows the sleeve to directly drive the membrane tube blown out by the die head to rise, it eliminates the need to cut the membrane tube before processing, thus avoiding waste. Furthermore, it requires only one operator, making it convenient for workers, reducing labor intensity, and improving productivity. The clamping module clamps the membrane tube on the inner wall of the sleeve, improving the stability of the sleeve pulling the membrane tube upwards. The sliding plate allows the clamping module to slide, changing its clamping position on the inner wall of the sleeve, thus clamping the membrane tube completely on the inner wall of the sleeve, improving the device's practicality. The cooperation between the clamping plate and the No. 3 spring allows for adjustment of the clamping plate's length. Even after the adjustment module adjusts the arc plate, the clamping plate still cooperates with it, pushing the membrane tube tightly against the inner wall of the arc plate, further enhancing the device's practicality.

[0005] However, this does not solve the problem that existing packaging film manufacturing equipment is generally not conducive to convenient cutting of packaging film during use, nor is it convenient to disassemble and replace the take-up roller, which affects the labor intensity of manual labor and the efficiency of disassembling and replacing the take-up roller in packaging film manufacturing equipment. Utility Model Content

[0006] The purpose of this invention is to provide a PLA bio-based biodegradable packaging film manufacturing equipment to solve the problems mentioned in the background art, such as the inconvenience of cutting the packaging film and disassembling and replacing the winding roller, which affects the labor intensity and efficiency of disassembling and replacing the winding roller.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PLA bio-based biodegradable packaging film manufacturing equipment, comprising a frame and connecting blocks. Connecting blocks are installed on both sides of the frame, and connecting blocks are installed on the side of each connecting block away from the frame. A servo motor is installed on the side wall of the frame, and a power motor is installed on the side wall of each connecting block. A cover is installed on the surface of the power motor. Three sets of support frames with equal spacing are installed on the side of the frame away from the servo motor. A first roller is movably installed on the surface of each support frame, and a second roller is movably installed on the surface of each support frame away from the first roller. A packaging film body is provided on the outside of the frame, and a winding roller body is provided at the top of each connecting block.

[0009] Preferably, a first electric push rod is symmetrically installed on the side wall of the connecting frame away from the movable support, and a pressure block is installed on the output end of each of the first electric push rods.

[0010] Preferably, the output end of the power motor is equipped with a rotating shaft, and the surface of the rotating shaft is provided with a groove.

[0011] Preferably, flat blocks are installed on both sides of the take-up roller body, and the grooves are all matched with the flat blocks.

[0012] Preferably, bearings are symmetrically fitted on the surface of the take-up roller body, and annular slide rails are installed on the surface of each connecting block.

[0013] Preferably, a second electric push rod is installed at the top of each connecting block, and a lifting slide rail is installed at the output end of each second electric push rod.

[0014] Preferably, the bearing is movably connected to the lifting slide rail and the annular slide rail, and the interior of each connecting block is equipped with a guide rail.

[0015] Preferably, sliders are installed on the side walls of the lifting slide rails, and the sliders are slidably connected to the guide rails.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the packaging film manufacturing equipment not only realizes the convenient cutting of packaging film, but also facilitates the disassembly and replacement of the winding roller, reducing the labor intensity of manual labor and improving the efficiency of disassembling and replacing the winding roller.

[0017] (1) Turn on the power motor. With the support of the connecting block, the power motor drives the winding roller body to rotate and wind up. The servo motor drives the heating roller to rotate and dry the packaging film body. When cutting is required, the first electric push rod drives the pressure block to move downward. With the cooperation of the side plate, the pressure block presses the packaging film body. The stepper motor drives the threaded rod to rotate and the threaded rod drives the threaded block to move.

This realizes the convenient cutting of packaging film by the packaging film manufacturing equipment and facilitates the convenient cutting of packaging film.

[0018] (2) When the take-up roller body needs to be replaced, rotate the rotating shaft so that the groove on the surface of the rotating shaft faces the worker. The second electric push rod drives the lifting slide rail to move downward. The worker pulls the take-up roller body. Under the support of the bearing, the take-up roller body drives the bearing to move outward to the surface of the lifting slide rail, so that the flat block is separated from the groove. Replace the take-up roller body. After the replacement is completed, move the take-up roller body and the two sets of bearings to the surface of the annular slide rail so that the bearing and the annular slide rail cooperate and the flat block and the groove cooperate. Open the second electric push rod in the opposite direction. Under the support of the connecting block, the second electric push rod drives the lifting slide rail to move in the opposite direction, so that the lifting slide rail moves upward and the bearing and the lifting slide rail are in close contact. The bearing rotates on the surface of the lifting slide rail to continue collecting. This realizes the convenient disassembly and replacement of the take-up roller in the packaging film manufacturing equipment, reduces the labor intensity of the workers, and improves the efficiency of disassembly and replacement of the take-up roller in the packaging film manufacturing equipment.
