Description

Technical Field

[0001] The utility model belongs to the technical field of release paper testers, and particularly relates to a full-automatic smoothness tester for release paper. Background Technique

[0002] As a special material, release paper is designed to prevent prepregs from sticking and effectively protect them from contamination. The smoothness tester is an indispensable tool for detecting various high-smooth papers and is widely used in the performance testing of high-smooth papers and cardboard. In the quality inspection process of release paper, the full-automatic smoothness tester plays a crucial role in accurately evaluating its performance.

[0003] To ensure the accuracy of test results, before measuring the thickness and smoothness of release paper, its surface must be strictly dusted. For example, the Chinese utility model patent (publication number CN216283421U) introduces a full-automatic smoothness tester that uses high-pressure air flow to act on the surface of release paper to achieve the effect of dust removal. However, this design has an obvious defect: its open structure causes the dust removed from the surface of release paper by the high-pressure air flow to disperse disorderly into the surrounding environment, which not only seriously deteriorates the working environment of the staff but also has the potential risk of dust reattaching to the surface of release paper.

[0004] Therefore, it is very necessary to invent a full-automatic smoothness tester for release paper. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a full-automatic smoothness tester for release paper, which includes a test box, a unwind roller, an electrostatic eliminator, an air flow dust collector, and an air pump. The unwind roller rotatably installed inside the test box is wound with release paper, and a dust removal box with an electrostatic eliminator and an air flow dust collector is fixedly installed. The dust removal box of the electrostatic eliminator and the air flow dust collector is located on one side of the unwind roller. Among them, the air flow channel arranged in the installation boss of the air flow dust collector is communicated with the output end of the air pump, and the air pump is fixedly installed outside the test box; the air flow dust collector includes a delivery port, an air flow nozzle, a guiding shoulder, and an air flow pipe. The two delivery ports are mirror-symmetrically penetrated and opened on the dust removal box. Installation bosses are symmetrically installed up and down inside the dust removal box, and numerous air flow nozzles are linearly arranged on the installation bosses; a guiding shoulder is fixedly installed inside the dust removal box, and an air flow pipe communicated with each other is installed outside it.

[0006] Preferably, the output end of the winding motor built in the test box is fixed to any end of the winding roller. A number of reasonably distributed guiding and conveying rollers are rotatably installed inside the test box, and a box cover is installed on the test box.

[0007] Preferably, the release paper unrolled from the unwinding roller will first pass through two electrostatic eliminators arranged in a mirror image, and then enter the dust removal box through the conveying port.

[0008] Preferably, a thickness detector and a smoothness detector are fixedly installed inside the test box, and they are arranged on one side of each other. After the release paper passes through the thickness detector and the smoothness detector, it is wound onto the winding roller through the guiding and conveying rollers.

[0009] Preferably, each mounting boss is provided with an inclined surface, and a number of air nozzles are linearly distributed on this inclined surface. The air flow generated by the air pump passes through the air flow channel arranged inside the mounting boss and is ejected through the air nozzles.

[0010] Preferably, the air flow ejected by the air nozzles acts on the surface of the release paper in an inclined manner, and there is an included angle between the air flow and the surface of the release paper.

[0011] Preferably, the guiding shoulder is of an arc structure, and it is distributed on the upper and lower sides inside the dust removal box. The end of the guiding shoulder comes into contact with the surface of the release paper, and its end surface is a smooth surface.

[0012] Preferably, the root of the guiding shoulder is fixed to the dust removal box, and an exhaust port is provided on one side of the root. The exhaust port is opened through the dust removal box, and the exhaust port is communicated with the air flow pipeline.

[0013] Preferably, an exhaust port is provided on the pipeline connecting the two air flow pipelines. An exhaust fan is installed on the exhaust port, and the exhaust fan is installed on the outside of the test box.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Through the dual guarantee design of electrostatic elimination and air flow dust removal, the utility model effectively removes the static electricity on the surface of the release paper, avoids the dust adsorption caused by static electricity, and at the same time uses the high-pressure air flow to act precisely on the surface of the release paper through the air nozzles with elaborate layout and angle optimization, realizing the comprehensive and uniform removal of dust and ensuring the high cleanliness of the surface of the release paper before testing. In addition, the arc-shaped smooth surface design of the guiding shoulder not only has good contact with the release paper, but also can guide the air flow and dust to flow along a specific path, and quickly discharge them from the dust removal box through the exhaust port communicated with the air flow pipeline, effectively avoiding the secondary pollution of dust. Furthermore, the exhaust fan installed on the pipeline connecting the two air flow pipelines can accelerate and orderly discharge the dust and waste gas generated during the dust removal process, and then connect to the dust collection pipeline for further collection, creating a cleaner and healthier working environment for the staff, and overall improving the dust removal efficiency and test accuracy of the tester.

[0023] As shown in Figure 1 to Figure 3 shown:

[0024] An automatic smoothness tester for release paper provided by the utility model includes a test box 1, a unwind roller 2, an electrostatic eliminator 3, an air flow dust collector 4 and an air pump 5. The unwind roller 2 rotatably installed inside the test box 1 is wound with release paper, and a dust removal box 41 with an electrostatic eliminator 3 and an air flow dust collector 4 fixedly installed therein is provided. The electrostatic eliminator 3 and the dust removal box 41 of the air flow dust collector 4 are located on one side of the unwind roller 2. Among them, an air flow channel provided in the mounting boss 43 of the air flow dust collector 4 is communicated with the output end of the air pump 5, and the air pump 5 is fixedly installed outside the test box 1; the air flow dust collector 4 includes a delivery port 42, an air flow nozzle 44, a guiding shoulder 45 and an air flow pipe 46. The two delivery ports 42 are mirror-symmetrically penetrated and opened on the dust removal box 41. Inside the dust removal box 41, mounting bosses 43 are symmetrically installed up and down in a mirror image manner, and a plurality of air flow nozzles 44 are linearly arranged on the mounting bosses 43; a guiding shoulder 45 is fixedly installed inside the dust removal box 41, and an air flow pipe 46 communicated with each other is installed outside it.

[0025] Further, a winding motor is built in the test box 1, and its output end is firmly connected to one end of the winding roller 6, ensuring the stable rotation of the winding roller 6. At the same time, a plurality of guiding and conveying rollers 11 are reasonably distributed inside the test box 1. The rotatably installed guiding rollers 11 provide a strong guarantee for the stable transmission of the release paper during the test process. A box cover 9 is installed on the test box 1.

[0026] Further, the release paper released from the unwind roller 2 first passes through two mirror-symmetrically arranged electrostatic eliminators 3, which effectively remove the static electricity on the surface of the release paper and avoid the problem of static electricity attracting dust. Subsequently, the release paper passes through the delivery port 42 and enters the dust removal box 41 to prepare for the next dust removal treatment.

[0027] Further, a thickness detector 7 and a smoothness detector 8 are also fixedly installed inside the test box 1. These two detectors are arranged on one side of each other to form a comprehensive detection of the quality of the release paper. After passing through these two detectors, the release paper is guided by the guiding and conveying rollers 11 and finally wound onto the winding roller 6.

[0028] Further, at least one inclined surface is provided on each of the mounting bosses 43 inside the dust removal box 41, and a plurality of air flow nozzles 44 are linearly distributed on each inclined surface. The air flow generated by the air pump 5 passes through the air flow channel inside the mounting boss 43 and is finally sprayed onto the surface of the release paper in an inclined manner through the air flow nozzles 44. This design not only ensures the uniform distribution of the air flow but also reduces the direct impact of the air flow on the surface of the release paper.

[0029] Furthermore, the guiding shoulder 45 is of an arc structure and is distributed at the upper and lower positions inside the dust removal box 41. Its end is in close contact with the surface of the release paper, and the end surface is smooth. This design helps to guide the airflow and dust to flow along a specific path. At the same time, the root of the guiding shoulder 45 is firmly fixed to the dust removal box 41, and an exhaust port is provided on one side of the root. The exhaust port communicates with the air flow pipe 46, ensuring that the dust carried by the air flow can be quickly discharged.

[0030] Furthermore, an exhaust port is provided on the pipe connecting the two air flow pipes 46, and an exhaust fan 10 is installed at this port. The exhaust fan 10 is installed outside the test box 1. Its strong suction can further enhance the dust removal effect, quickly discharging the dust and waste gas generated during the dust removal process from the test box, providing a cleaner and healthier working environment for the staff. The exhaust fan 10 is connected to the dust collection pipe, and the dust collection pipe is connected to the dust suction box, so as to discharge the dust into the dust suction box.

[0031] The working principle is as follows: First, before the test starts, the release paper wound on the unwind roller 2 is prepared. The winding motor inside the test box 1 is started, and its output end is firmly connected to one end of the winding roller 6, ensuring that the winding roller 6 can rotate stably during the test. At the same time, a plurality of guiding and conveying rollers 11 reasonably distributed inside the test box 1 are also in a rotating state, providing a strong guarantee for the smooth transmission of the release paper.

[0032] Then, the unwind roller 2 starts to release the release paper, and the release paper first passes through two electrostatic eliminators 3 arranged symmetrically. Through their internal working mechanisms, these two electrostatic eliminators 3 effectively remove the static electricity on the surface of the release paper, avoiding the problem of static electricity attracting dust, and thus ensuring the cleanliness of the release paper before entering the dust removal box 41.

[0033] Next, the release paper after electrostatic elimination treatment passes through the conveying port 42 and enters the dust removal box 41. Inside the dust removal box 41, the air flow nozzles 44 installed on the mounting boss 43 start to work. The air flow generated by the air pump 5 passes through the air flow channel inside the mounting boss 43 and finally sprays onto the surface of the release paper in an inclined manner through the air flow nozzles 44. This design not only ensures the uniform distribution of the air flow but also reduces the direct impact of the air flow on the surface of the release paper, thus achieving effective dust removal on the surface of the release paper.

[0034] Meanwhile, the guiding shoulder 45 inside the dust removal box 41 also plays an important role. When the airflow ejected by the airflow nozzle 44 acts on the surface of the release paper, dust and impurities will be carried up by the airflow and flow along the arc surface of the guiding shoulder 45 to the exhaust port. At this time, the exhaust port is communicated with the airflow pipe 46, and the dust carried up by the airflow can quickly enter the airflow pipe 46 through the exhaust port. And the exhaust fan 10 arranged on the pipe communicated between the two airflow pipes 46 also starts to work. The powerful suction of the exhaust fan 10 can further enhance the dust removal effect and quickly discharge the dust and waste gas generated during the dust removal process from the test box 1.

[0035] Finally, the release paper that has undergone static elimination, dust removal, and thickness and smoothness detection will be guided by the guiding conveying roller 11 and finally wound onto the winding roller 6. The whole test process realizes the full automation from unwinding, static elimination, dust removal to detection, providing users with an efficient and accurate test experience.

[0036] Any technical solution using the technical solution of the present utility model, or designed by those skilled in the art inspired by the technical solution of the present utility model to achieve the above technical effects, shall fall within the protection scope of the present utility model.
