Description

Technical Field

[0001] This utility model relates to the field of paper inspection technology, specifically a paper feeding adjustment mechanism for an inspection machine. Background Technology

[0002] During paper processing, a quality control machine is needed to inspect the surface of the paper to be processed, so as to facilitate subsequent paper processing. When using a quality control machine to inspect the surface of the paper to be processed, a paper adjustment mechanism is needed to ensure that the paper enters the quality control machine at the appropriate speed and position to improve the inspection accuracy and efficiency and ensure the smooth progress of paper inspection.

[0003] Accurate adjustment of paper tension is crucial in the paper inspection process. Operators often make mistakes when adjusting the paper tension, such as excessive adjustment stroke, which can lead to excessive paper tension, paper breakage, and reduced inspection efficiency. Therefore, there is an urgent need to develop a paper feeding adjustment mechanism for inspection machines to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a paper feeding adjustment mechanism for an inspection machine, which solves the problem that operators often cause excessive adjustment stroke when adjusting paper tension, leading to excessive paper tension, paper breakage, and reduced inspection efficiency.

[0005] To achieve the above objectives, this utility model provides a paper feeding adjustment mechanism for an inspection machine through the following technical solution: a housing, a winding assembly is provided on one side of the top of the housing, and a fixed box is fixedly connected to the top of the housing near the winding assembly.

[0006] It also includes a tension safety adjustment mechanism, which includes a support rod that runs through the interior of the fixed box. The bottom end of the support rod is fixedly connected to a conveyor roller frame, and the outer side of the bottom end of the support rod is fixedly connected to a first connecting seat. A first abutting rod is movably installed inside the first connecting seat, and a positioning bolt for positioning the first abutting rod is threaded on one side of the first connecting seat. Two sets of second connecting seats are fixedly connected to the top of the interior of the fixed box. A second abutting rod that cooperates with the first abutting rod is movably installed inside the second connecting seat, and a reset component is also provided at the bottom of the second connecting seat.

[0007] Preferably, the reset assembly includes a reset spring disposed on one side of the bottom of the second connecting seat, one end of the reset spring being fixedly connected to one side of the second abutment rod for elastic reset of the second abutment rod.

[0008] Preferably, it also includes an antistatic mechanism, which includes a plasma air bar disposed on one side of the top of the fixed box, nozzles extending into the fixed box are installed at equal intervals at the bottom of the plasma air bar, and a plasma generator is fixedly installed on one side of the plasma air bar. An air pump is fixedly connected to one end of the plasma air bar through a pipe, and a filter assembly is provided on the air pump inlet pipe.

[0009] Preferably, the filter assembly includes a filter box disposed on the other side of the top of the fixed box, and the filter box is provided with multiple sets of filter plates.

[0010] Preferably, the filter plate is a nanoporous plate, and the number of filter plates is at least two sets.

[0011] Preferably, two sets of spring sleeves are provided on the top of the housing away from the winding assembly, and a pressure roller is installed at the bottom of the spring sleeves via a shaft bracket.

[0012] This invention provides a paper feeding adjustment mechanism for an inspection machine. Compared with the prior art, it has the following advantages.

[0013] 1. The operator guides the paper to be inspected through the inside of the conveyor roller frame, pulls the support rod to move the conveyor roller frame upward to stretch the paper and adjust the tension. As the support rod continues to move upward, it drives the first connecting seat to move synchronously, causing the first abutting rod to move upward to abut the second abutting rod. The second abutting rod moves horizontally within the second connecting seat and stretches the return spring. Its other end abuts the top of the support rod, limiting and locking the position of the support rod. This prevents the conveyor roller frame from breaking due to excessive tension caused by excessive travel of the support rod, thus realizing the function of safely adjusting the paper tension during the paper feeding process.

[0014] 2. An air pump draws in air, which enters a filter box and a filter plate for filtration. The air is then sent to the plasma air bar through pipes. At the same time, the plasma generator works to ionize the air inside the plasma air bar into plasma. Under the air pump's airflow, the plasma is sent into the fixed box through the nozzle, where it neutralizes the opposite static charge on the paper surface, eliminating static electricity and preventing the paper from adsorbing dust and impurities, thus ensuring the paper surface is clean during inspection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] First implementation method:

[0023] refer to Figure 1-5 A paper feeding adjustment mechanism for an inspection machine includes a housing 1, a winding assembly 101 is provided on one side of the top of the housing 1, and a fixed box 2 is fixedly connected to the top of the housing 1 near the winding assembly 101.

[0024] It also includes a tension safety adjustment mechanism 3, which includes a support rod 301 that runs through the inside of the fixed box 2. The bottom end of the support rod 301 is fixed to the conveyor roller frame 302, and the outer side of the bottom end of the support rod 301 is fixed to the first connecting seat 303. The first connecting seat 303 is movably installed with a first abutting rod 304, and a positioning bolt for positioning the first abutting rod 304 is threaded on one side of the first connecting seat 303. Two sets of second connecting seats 305 are fixed to the top inside the fixed box 2. The second connecting seat 305 is movably installed with a second abutting rod 306 that cooperates with the first abutting rod 304, and a reset component is also provided at the bottom of the second connecting seat 305.

[0025] The reset assembly includes a reset spring 307 disposed on one side of the bottom of the second connecting seat 305. One end of the reset spring 307 is fixedly connected to one side of the second abutment rod 306 for elastic reset of the second abutment rod 306. Two sets of spring sleeve seats 5 are also disposed on the top of the housing 1 away from the winding assembly 101, and a pressure roller 501 is mounted on the bottom of the spring sleeve seat 5 through a shaft frame.

[0026] First, the operator guides the paper to be inspected through the inside of the conveyor roller frame 302, and then the inspection equipment pulls the paper to move, thereby detaching it from the outside of the winding assembly 101 for paper feeding.

[0027] The operator pulls the support rod 301 to move the conveyor roller frame 302 upward and stretch the paper, thereby achieving the function of adjusting the paper tension. When the operator continues to pull the support rod 301 upward, the support rod 301 drives the first connecting seat 303 to move synchronously, and drives the first abutting rod 304 to move upward to the side of the second abutting rod 306 to abut.

[0028] One end of the second abutment rod 306 is abutted inside the second connecting seat 305 and moves horizontally, causing the return spring 307 to be elastically stretched, so that the other end of the second abutment rod 306 abuts against the top of the support rod 301, thereby limiting and locking the movement position of the support rod 301. This avoids the problem that when the operator pulls the support rod 301 to adjust the paper tension, the movement of the support rod 301 is too large, which would cause the conveyor roller frame 302 to stretch the paper tension too much and cause the paper to break. This achieves the function of safely adjusting the paper tension.

[0029] When it is necessary to release the movement position limitation of the support rod 301, the operator pushes the support rod 301 downward, causing the first connecting seat 303 and the first abutment rod 304 to move downward simultaneously. The abutment force of the first abutment rod 304 on the second abutment rod 306 gradually decreases until it disappears. At this time, the return spring 307, which is in an elastic tension state, will release its elastic potential energy and elastically contract, causing the second abutment rod 306 to move horizontally in the opposite direction inside the second connecting seat 305, so that the other end of the second abutment rod 306 disengages from the top of the support rod 301, thereby releasing the limitation lock on the support rod 301.

[0030] The first contact rod 304 is moved vertically inside the first connecting seat 303, thereby changing the relative distance between the first contact rod 304 and the second contact rod 306, which makes it easier to adapt to paper with different tensions.

[0031] The high elasticity of the spring sleeve 5 can drive the pressure roller 501 to apply pressure to the conveyed paper, thereby eliminating the stress inside the paper and preventing deformation caused by stress inside the paper.

[0032] Second implementation method:

[0033] When paper is unwound and fed, static electricity is easily generated due to friction between the surface of the paper and the outer surface of the paper being wound. This static electricity then attracts dust and impurities from the air, reducing the cleanliness of the paper surface during the inspection process.

[0034] refer to Figure 1-2In the second embodiment of this utility model, it also includes an antistatic mechanism 4. The antistatic mechanism 4 includes a plasma air bar 401 disposed on one side of the top of the fixed box 2. The bottom of the plasma air bar 401 is equidistantly equipped with nozzles 402 extending into the interior of the fixed box 2. A plasma generator 403 is fixedly installed on one side of the plasma air bar 401. One end of the plasma air bar 401 is fixedly connected to an air pump 404 through a pipe. The air inlet pipe of the air pump 404 is provided with a filter assembly.

[0035] The filter assembly includes a filter box 405 disposed on the other side of the top of the fixed box 2, and the filter box 405 is provided with multiple sets of filter plates 406. The filter plates 406 are nanoporous plates, and the number of filter plates 406 is at least two sets.

[0036] After the air pump 404 is started, it draws air from the outside environment. The air first enters the filter box 405 and passes through multiple sets of filter plates 406 in sequence. The filter plates 406 intercept and filter the dust and impurities in the air to obtain clean air. The filtered clean air is then transported to the plasma air bar 401 through the pipes.

[0037] The plasma generator 403 generates a high-voltage electric field that ionizes the air inside the plasma fan bar 401 to form plasma. Under the continuous air supply of the air pump 404, the plasma is evenly transported to the inside of the fixed box 2 through the nozzle 402 with the airflow. It neutralizes the opposite charge generated on the paper surface due to static electricity, thereby eliminating static electricity on the paper surface and preventing the paper from adsorbing dust and impurities in the air due to static electricity, thus ensuring the cleanliness of the paper surface during the inspection process.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
