Description

Technical Field

[0001] This utility model relates to the field of film stretching technology, and more specifically to a film longitudinal stretching device. Background Technology

[0002] A thin film is a thin, flexible, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, a thin film is defined as a two-dimensional material formed by the deposition of atoms, molecules, or ions onto the surface of a substrate. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. Thin films are widely used in the electronics, machinery, and printing industries. After production, thin films require a longitudinal stretching device to stretch and wind them.

[0003] For example, the prior art publication number CN207059210U describes an online longitudinal stretching device for producing longitudinally straight tearable films. This utility model involves primary thickness measurement, secondary thickness measurement, and automatic air ring linkage, so that the blown film is thick in the middle and thin at both sides before stretching, and a high-quality film with excellent thickness deviation is obtained after the stretching process.

[0004] However, the above-mentioned prior art still has the following problems when in use: since the unwinding roller is located above the stretching device, the operator needs to use a propping tool to replace the unwinding roller, and there is a danger when operating from a high place. Based on this, the present invention provides a film longitudinal stretching device with high safety. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a film longitudinal stretching device. By driving the connecting column to rotate via a motor, the unwinding roller located at the top of the housing is moved closer to the ground, thus facilitating the operation of the unwinding roller by the operator without requiring them to stand at a height, ensuring high operational safety. Afterward, the housing is rotated back to its original position, and the unwinding roller and the take-up roller can be used in conjunction to longitudinally stretch the film as it passes through multiple stretching rollers, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a film longitudinal stretching device, comprising a base, a stretching component and a rotating component at the top of the base, the stretching component comprising a housing, an unwinding roller for conveying film at the top of the inner cavity of the housing, a winding roller for collecting film at the front side of the bottom side of the inner cavity of the housing, and a plurality of stretching rollers arranged sequentially from top to bottom in the inner cavity of the housing, the rotating component comprising two support plates, the two support plates being fixed to the top of the base respectively, and the two support plates being distributed on both sides of the housing, each of the two support plates having a connecting column passing through it, and the connecting column being rotatably connected to the support plate, one end of each of the two connecting columns being fixed to the outer wall of the housing, and a motor for driving the connecting column to rotate is fixedly provided at the rear end of the connecting column located on one side of the housing, the motor being used to rotate the top of the housing to a lower position, thereby facilitating the operation of the unwinding roller by the operator.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figure 1-5This utility model provides a film longitudinal stretching device, including a base 1, a stretching component 2 and a rotating component 3 at the top of the base 1, the stretching component 2 including a housing 201, an unwinding roller 202 for conveying film at the top of the inner cavity of the housing 201, a winding roller 203 for collecting film at the front side of the bottom side of the inner cavity of the housing 201, and a plurality of stretching rollers 204 arranged sequentially from top to bottom in the inner cavity of the housing 201.

[0026] The rotating assembly 3 includes two support plates 301, which are fixed to the top of the base 1 and distributed on both sides of the housing 201. Each support plate 301 has a connecting post 302 through it, and the connecting post 302 is rotatably connected to the support plate 301. One end of each connecting post 302 is fixed to the outer wall of the housing 201. A motor 303 for driving the connecting post 302 to rotate is fixed at the rear end of the connecting post 302 on one side of the housing 201. The motor 303 is used to rotate the top of the housing 201 to a lower position, so as to facilitate the operation of the unwinding roller 202 by the operator.

[0027] Furthermore, a mounting base 4 is fixedly provided at the bottom of the motor 303. The mounting base 4 is fixed to the support plate 301 on one side of the housing 201. The motor 303 is supported by the mounting base, which can improve the stability of the motor 303. A controller 12 for controlling the motor 303 is fixedly provided on one side of the top of the base 1, which makes it convenient for the staff to adjust the position of the housing 201.

[0028] The base 1 has multiple mounting holes 13 at its top end. The mounting holes 13 are spaced apart from the two support plates 301. In actual use, workers can use bolts to fix the base 1 to the ground, thereby improving the stability of the entire device.

[0029] In use, the operator first uses the controller 12 to control the motor 29 to drive the connecting column 302 to rotate, so that the housing 201 rotates and drives the unwinding roller 202 to a position close to the ground, which makes it convenient for the operator to place the film to be stretched. At the same time, it is convenient for the operator to pass the film through multiple stretching rollers 204 and wind it onto the take-up roller 203. Then the housing 201 can be rotated back to its original position, and the unwinding roller 202 and the take-up roller 203 can be used to make the film longitudinally stretched as it passes through multiple stretching rollers 204, and finally automatically wound onto the take-up roller 203.

[0030] Refer to the instruction manual appendix Figure 1-5 The housing 201 has openings 5 ​​at both the front and rear ends. Mounting plates 6 are slidably installed inside the two openings 5. A rotating rod 7 passes through one side of each mounting plate 6 and is rotatably connected to the mounting plate 6. The unwinding roller 202 and the winding roller 203 are detachably mounted on the two rotating rods 7, which facilitates the installation and removal of the unwinding roller 202 and the winding roller 203 by the workers.

[0031] Furthermore, mounting base 2 8 is fixedly provided on one side of each of the two mounting plates 6, and motor 2 9 is fixedly provided at the top of each of the two mounting base 2 8. The output shafts of the two motor 2 9 are respectively fixed to one end of the two rotating rods 7. The motor 2 9 can drive the rotating rods 7 to drive the unwinding roller 202 and the winding roller 203 to rotate automatically, thereby realizing the unwinding and winding of the film.

[0032] Furthermore, an outlet 10 is provided at the rear end of the housing 201, and a detachable baffle 11 is fixed inside the outlet 10. Multiple stretching rollers 204 can be detached and fixed on the baffle 11. By removing the baffle 11, multiple stretching rollers 204 can be disassembled and replaced.

[0033] By setting mounting plates 6 at the top and front of the housing 201, the unwinding roller 202 and the take-up roller 203 are supported by the mounting plates 6. At the same time, the unwinding roller 202 and the take-up roller 203 are automatically rotated by the rotating rod 7 driven by the motor 303, thereby completing the unwinding and take-up of the film. The operator only needs to loosen the multiple bolts between the mounting plate 6 and the housing 201 to remove the mounting plate 6 and replace the unwinding roller 202 and the take-up roller 203 on the two rotating rods 7. The baffle 11 can also be removed to disassemble and replace the multiple stretching rollers 204.
