Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically to a size measuring device for plastic film processing. Background Technology

[0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging and as coating layers. Plastic films are widely used in the food, pharmaceutical, and chemical industries. When cutting plastic films to specified sizes, dimensional measuring devices are used to measure the film. For example, patent application number 202222148418.X, entitled "A Film Length Measuring Device," includes a cutting mechanism for cutting the film and a measuring mechanism for measuring the length of the film after passing through the measuring mechanism. The film is connected to a cutting mechanism. After passing through the cutting mechanism and the measuring mechanism, it is wound onto a rewinding roller. The measuring mechanism includes a support roller, which is supported at the bottom of the film and can rotate with the movement of the film; a pressure roller, which is located above the support roller and presses the film onto the support roller. The pressure roller rotates with the movement of the film; and a photoelectric sensor, which includes a transmitter and a receiver, located on opposite sides of the pressure roller. The pressure roller has multiple through holes through which the light emitted by the transmitter passes. By detecting the signal changes of the photoelectric sensor, the length of the film can be accurately detected, thereby improving the accuracy of length measurement.

[0003] The aforementioned technologies have the following drawbacks: the measuring device uses a handle to control the rotation of the traction roller, thereby moving the plastic film. Since the worker manually rotates the handle, it is impossible for the worker to stop the rotation of the traction roller in time when the plastic film reaches the specified size. This results in a large deviation in the measurement accuracy of the size measuring device, reducing its practicality.

[0004] Therefore, it is necessary to redesign and modify the dimensional measuring equipment to effectively prevent its low practicality. Utility Model Content

This enhances the measurement accuracy of the dimensional measuring equipment and improves its practicality.

[0015] 2. This utility model uses a compression spring, mounting frame, and auxiliary roller to compress the plastic film, making the plastic film adhere to the traction roller.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] like Figures 1 to 7 As shown, the present invention provides a size measuring device for plastic film processing, including a housing 1, a support frame 2 fixedly connected to the top of the housing 1, and a traction roller 3 movably connected inside the support frame 2;

[0026] The measuring mechanism includes a rotary encoder 4 and a motor 5, which are fixedly connected to the left and right sides of the support frame 2, respectively. The output ends of the rotary encoder 4 and the motor 5 extend into the interior of the support frame 2 and are fixedly connected to the surface of the traction roller 3.

The top of the anti-slip rubber 8 is movably connected to the bottom of the traction roller 3. A control panel 9 is fixedly connected to the front of the housing 1. The back of the control panel 9 extends into the interior of the housing 1. The control panel 9 is electrically connected to the rotary encoder 4, the motor 5, and the piston cylinder 6 via signal lines. A pressing mechanism is provided inside the support frame 2, and a support mechanism is provided on the top of the housing 1.

[0027] refer to Figure 7 The extrusion mechanism includes a compression spring 10 fixedly connected to the top of the support frame 2. The bottom of the compression spring 10 is fixedly connected to a mounting frame 11. An auxiliary roller 12 is movably connected inside the mounting frame 11. The bottom of the auxiliary roller 12 extends to the outside of the mounting frame 11. A guide mechanism is provided on the surface of the mounting frame 11.

[0028] As a technical optimization of this utility model, by setting up a compression spring 10, a mounting frame 11 and an auxiliary roller 12, the plastic film is squeezed to make the plastic film adhere to the traction roller 3, so as to avoid the traction roller 3 slipping when it drives the plastic film to move by rotating, thereby affecting the measurement accuracy of the size measuring equipment.

[0029] refer to Figure 6 The guiding mechanism includes guide grooves 13 respectively opened on both sides inside the support frame 2. The guide grooves 13 are located on the top of the traction roller 3. Limiting blocks 14 are fixedly connected to both sides of the mounting frame 11. The outer side of the limiting blocks 14 extends into the interior of the guide grooves 13.

[0030] As a technical optimization of this utility model, by setting the guide groove 13 and the limiting block 14, the mounting frame 11 and the auxiliary roller 12 are guided and limited, so as to avoid the mounting frame 11 and the auxiliary roller 12 from shifting, which would prevent the auxiliary roller 12 from effectively squeezing the plastic film.

[0031] refer to Figure 3 The support mechanism includes a support bracket 15 fixedly connected to the top of the outer shell 1 and located on both sides of the arc panel 7. A roller 16 is movably connected to the top of the support bracket 15, and the top of the roller 16 is movably connected to the bottom of the traction roller 3.

[0032] As a technical optimization of this utility model, the traction roller 3 is supported by the support bracket 15 to prevent the traction roller 3 from bending due to gravity, and the roller 16 is used to prevent the support bracket 15 from rubbing against the traction roller 3, thus preventing the traction roller 3 from being worn due to friction.

[0033] refer to Figure 7 The top of the mounting bracket 11 is fixedly connected to a dustproof cloth 17 located outside the compression spring 10, and the top of the dustproof cloth 17 is fixedly connected to the top of the support frame 2.

[0034] As a technical optimization of this utility model, a dustproof cloth 17 is provided to protect the compression spring 10, so as to prevent debris from adhering to the compression spring 10 and affecting the pressure applied by the compression spring 10 to the mounting bracket 11.

[0035] refer to Figure 2 The top of the inner shell 1 is fixedly connected to the reinforcing plates 18 located on both sides of the piston cylinder 6. The bottom of the reinforcing plates 18 is fixedly connected to the support column 19, and the bottom of the support column 19 is fixedly connected to the bottom of the inner shell 1.

[0036] As a technical optimization of this utility model, by setting up a reinforcing plate 18 and a support column 19, the load-bearing capacity of the outer shell 1 is improved, and the outer shell 1 is prevented from deforming due to poor load-bearing capacity.

[0037] The working principle and usage process of this utility model are as follows: In use, the rotary encoder 4 and motor 5 are started by controlling the control panel 9. The motor 5 drives the traction roller 3 and the output end of the rotary encoder 4 to rotate through the output end. The traction roller 3 drives the plastic film to move to the right through rotation. The rotary encoder 4 detects the number of rotations of the traction roller 3 through photoelectric conversion. When the traction roller 3 rotates to the specified number of rotations, the rotary encoder 4 will send a signal to the motor 5 through the control panel 9. When the motor 5 receives the signal, it will stop rotating. At the same time, the control panel 9 will control the piston cylinder 6 to start. The piston cylinder 6 drives the arc panel 7 and the anti-slip rubber 8 through the output end to squeeze the traction roller 3 to prevent the traction roller 3 from rotating due to inertia.

[0038] In summary, this dimensional measuring device for plastic film processing, by setting up a motor 5 to control the rotation of the traction roller 3, and using a control panel 9 and a rotary encoder 4 to control the motor 5, stops the motor 5 when the traction roller 3 has rotated to a specified number of revolutions. The piston cylinder 6, the arc panel 7, and the anti-slip rubber 8 are used to squeeze and position the traction roller 3, preventing it from rotating due to inertia. This enhances the measurement accuracy of the dimensional measuring device and improves its practicality.
