Technical Field

[0001] This utility model relates to the field of plastic bag production technology, specifically to a material receiving mechanism for a blown film machine used in plastic bag production. Background Technology

[0002] With the continuous advancement of science and the continuous improvement of people's living standards, the light packaging industry has developed vigorously, and plastic film is an important component of it. It is suitable for various high-end film packaging, plastic bag film, etc. In order to produce such plastic film, a plastic film blowing machine is needed. The blowing machine heats and melts plastic particles and then blows them into a film. Currently, after the blowing machine blows out the film, a material collection mechanism is needed to collect it.

[0003] Existing patent CN213802115U discloses a novel blown film machine take-up device, including a base plate. A first mounting seat and a second mounting seat are mounted on the base plate. A connector is movably mounted on the first mounting seat via a rotating shaft. A first groove is formed on the connector, and a take-up roller is disposed within the first groove. A plurality of first locking screws are threaded onto the connector, and the ends of the plurality of first locking screws abut against the side of the take-up roller. Two first rollers are provided on the second mounting seat. A first connecting seat and a second connecting seat are also provided on the second mounting seat. A connecting plate is hinged to the first connecting seat, and two second rollers are provided on the bottom surface of the connecting plate. The connecting plate is fixedly connected to the second connecting seat via second locking screws. The end of the take-up roller is sandwiched between the two first rollers and the two second rollers. This invention has a simple structure and facilitates the loading and unloading of the take-up roller.

[0004] The existing technology has the following problems:

[0005] 1. The existing blown film production machine's receiving mechanism has a large weight of take-up rollers after receiving the material, making it difficult for workers to quickly disassemble the take-up rollers. This also makes the disassembly process of the take-up rollers cumbersome, time-consuming, and labor-intensive, reducing the efficiency of receiving the material and failing to meet the usage requirements.

[0006] 2. The existing blown film extrusion machine for plastic bag production lacks a pressing function during the material collection process. This leads to the plastic film on the take-up rollers becoming loose or wrinkled during collection, reducing the collection efficiency and hindering its widespread adoption. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a material receiving mechanism for a blown film machine used in plastic bag production. This mechanism solves the problems of the current material receiving mechanism, which suffers from the large weight of the take-up roller after material receiving, making it difficult for workers to quickly disassemble the take-up roller. This also leads to a cumbersome disassembly process for the take-up roller and the lack of a clamping function. Consequently, the plastic film on the take-up roller is prone to loosening or wrinkling during material receiving.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a material receiving mechanism for a blown film machine used in plastic bag production, comprising a base plate, a side plate on one side of the top of the base plate, a motor on one side of the side plate, a rotating shaft at the output end of the motor, a disassembly / assembly assembly at one end of the rotating shaft, a rotating seat at one end of the disassembly / assembly assembly, a hydraulic cylinder below the disassembly / assembly assembly on the base plate, a support seat at the top of the hydraulic cylinder, a bracket on the back of the disassembly / assembly assembly on the base plate, a sleeve on one side of the top of the bracket, a spring inside the sleeve, a limit block at the bottom of the spring, a support rod at the bottom of the limit block, a U-shaped frame at the bottom of the support rod, a connecting rod inside the U-shaped frame, and a pressure roller on the outer surface of the connecting rod.

[0010] As a preferred embodiment of this utility model, one end of the electric push rod is fixedly connected to a fixing plate, and the other end of the electric push rod is fixedly connected to a clamping plate, wherein the clamping plate and the locking block are integrally formed.

[0011] As a preferred technical solution of this utility model, the number of positioning blocks is several groups, the positioning blocks are arranged in a circular array, the positioning blocks and the clamping plate are integrated, and the positions of the positioning blocks and the positions of the positioning grooves are corresponding to each other.

[0012] As a preferred technical solution of this utility model, the support base is fixedly connected to the hydraulic cylinder, the position of the support base corresponds to the position of the disassembly and assembly components, and the top of the support base is arc-shaped.

[0013] In a preferred embodiment of this utility model, the support rod is fixedly connected to the limiting block, the size of the limiting block is adapted to the size of the sleeve, and the limiting block is slidably connected to the inner wall of the sleeve.

[0014] In a preferred embodiment of this invention, the pressing roller is mounted on the connecting rod via a rotatable connection, and the size of the pressing roller is adapted to the size of the U-shaped frame.

[0015] Compared with the prior art, this utility model provides a material receiving mechanism for a blown film machine used in plastic bag production, which has the following advantages:

[0016] 1. This is a material receiving mechanism for a blown film machine used in plastic bag production. It includes an electric push rod, clamping plates, locking blocks, positioning grooves, positioning blocks, a hydraulic cylinder, and a support base. When installing the take-up roller, the two ends of the take-up roller body are first aligned with the corresponding clamping plates. Then, by activating the electric push rod, the locking blocks are pushed to engage with the inner wall of the take-up roller body, and the positioning blocks are inserted into the positioning grooves to position the take-up roller body, thus completing the installation operation. During disassembly, the hydraulic cylinder is activated to move the support base upwards to a specified height. Then, the electric push rod is activated to retract, causing the locking blocks and positioning blocks to move backwards synchronously, allowing the take-up roller body to fall directly onto the support base, completing the disassembly operation. This design makes the disassembly process of the take-up roller more convenient, saving time and effort, improving material receiving efficiency, and meeting usage requirements.

[0017] 2. This type of blown film production machine receiving mechanism, through the setting of a sleeve, spring, support rod, U-shaped frame and pressure roller, in the receiving process, firstly, the spring force pushes the support rod to move vertically along the inner wall of the sleeve until the pressure roller in the U-shaped frame contacts the plastic film on the outer surface of the take-up roller. Then, the pressure roller presses the plastic film tightly, so that the plastic film can be wound more tightly. This design gives the receiving mechanism a pressing function, avoiding the problem of loose or wrinkled plastic film on the take-up roller during receiving, improving the receiving effect and facilitating its promotion.
