Description

Technical Field

[0001] This utility model relates to the field of film processing equipment, and in particular to a plastic film spreading roller assembly. Background Technology

[0002] A spreading roller assembly is a device used for film spreading, mainly composed of several film spreading rollers. The outer surface of these spreading rollers has grooves that extend in a spiral pattern. The design of these grooves allows the film to fully unfold during the spreading process.

[0003] While existing spreading devices can guide the film using fixed rollers, they also have other problems during use. For example, they lack a quick tension adjustment function, making it impossible to control the tightness of the film during winding, which can easily cause the film to slip and arch, reducing the stability of the film after winding. Furthermore, they lack roller heating function. Although the left and right spiral threads on the roller surface can expand the film to both ends, the film has high plasticity at low or room temperature and is not easy to soften. Therefore, the wrinkles and unevenness that occur when passing through the left and right spiral threads are difficult to eliminate, reducing the spreading quality of the film. To solve the above problems, we propose a plastic film spreading roller assembly. Utility Model Content

[0004] The purpose of this invention is to provide a plastic film spreading roller assembly that solves the problems of existing spreading roller assemblies lacking both a quick tension adjustment function and a roller heating function.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plastic film spreading roller assembly, comprising a frame, a threaded rod threadedly connected to the top of the frame, a fixed frame rotatably connected to the bottom end of the threaded rod via a bearing, a flattening roller rotatably connected inside the fixed frame via a bearing, guide rollers rotatably connected to the front and rear ends inside the frame, an end cap bolted to one side of the flattening roller, a heater bolted through one side of the end cap, the other end of the heater extending into the interior of the flattening roller, left and right spiral threads formed on the surface of the heater, a controller bolted to one side of the frame, and through grooves formed on both sides of the frame.

[0006] The above technical solution can be used to quickly adjust the tension, which is simple and labor-saving to operate. It can control the tightness of the film during the winding process, and has good stability and flexibility. At the same time, it can also have a roller heating function, which makes the film easier to flatten after softening, improving the quality of eliminating wrinkles and unevenness, and has high practicality.

[0007] The present invention is further configured such that: guide rods are symmetrically welded to the top of the fixed frame, and the other end of the guide rods passes through and extends to the outside of the frame.

[0008] By adopting the above technical solution, the guide rod can limit the fixed frame and prevent it from flipping over during the up-and-down movement.

[0009] The present invention is further configured such that a throttle is installed at the top end of the threaded rod.

[0010] By adopting the above technical solution and by setting the throttle, it is easy for personnel to rotate the threaded rod.

[0011] The present invention is further configured such that both the fixing frame and the threaded rod are made of stainless steel.

[0012] Using the above technical solution, the fixed frame and threaded rod have the characteristics of high strength, low density and excellent corrosion resistance.

[0013] The present invention is further configured such that: mounting plates are symmetrically installed on both sides of the frame, and mounting holes are provided inside the mounting plates.

[0014] By adopting the above technical solution, the installation plate and mounting holes make it easy for personnel to fix the equipment to the machine table.

[0015] The present invention is further configured such that: the other end of the heater is fitted with a retainer, and the other side of the retainer is bolted to the inside of the flattening roller.

[0016] By adopting the above technical solution, the heater can be limited by the setting of the card holder, preventing the heater from colliding with the inner wall of the flattening roller due to falling.

[0017] The present invention is further configured such that the flattening roller is made of aluminum-silicon alloy.

[0018] By adopting the above technical solution, the flattening roller has a high thermal conductivity, ensuring rapid heat transfer.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model first fixes the frame to the machine base. After the frame is fixed, one end of the film is passed through and connected to the winding equipment. After the film is connected, it will be at the top of the two guide rollers and the bottom of the flattening roller. Then, the throttle is held by hand to drive the threaded rod to rotate. When the threaded rod rotates, it will drive the fixed frame and the flattening roller to move down. When the flattening roller moves down, it will push the film to tighten it. It has a quick tension adjustment function, is simple and labor-saving to operate, and can control the tightness of the film during the winding process. It has good stability and flexibility.

[0021] 2. This utility model utilizes a heater to generate heat energy by passing current through a resistive material after startup. The heat energy, once generated, is sealed by the end caps and heats the inside of the flattening roller. The heat inside the flattening roller is transferred to the surface and then to the film. Under the action of the heat energy, the film softens and expands outwards to both ends as the flattening roller rotates. It has a roller heating function, making the softened film easier to flatten, improving the quality of eliminating wrinkles and unevenness, and has high practicality. Attached Figure Description
