Description

Technical Field

[0001] This utility model relates to the field of release paper production technology, specifically to a release paper uniform coating production equipment. Background Technology

[0002] Release paper, also known as release liner, anti-sticking paper, or silicone paper, is a special type of paper used to prevent prepreg materials from sticking together and protecting them from contamination. It typically consists of three layers: a base paper, a coating, and a silicone oil layer. Release paper is widely used in industries such as electronics, food, medical, automotive foam, and printing, especially when used with adhesive materials (such as tapes). Release paper can be classified in several ways: according to whether it has been plastic-coated, it can be divided into plastic-coated and non-plastic-coated release paper; according to the type of release agent, it can be divided into silicone release paper and non-silicone release paper. Its main technical indicators include silicone oil coating amount, peel strength (room temperature and aging), and residual tack rate, which directly affect the performance and effectiveness of the release paper.

[0003] In the production of release paper, a coating tube is typically used for spraying to form a uniform coating layer on the paper strip surface. During this process, the coating tube needs to remain stationary to ensure even spraying of the coating material onto the paper strip. However, due to the stationary nature of the coating tube, the sprayed coating material often accumulates in specific areas of the paper strip, resulting in an uneven coating layer. This unevenness can negatively impact the quality and performance of the release paper. Therefore, a uniform coating production device for release paper is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a uniform coating production equipment for release paper to solve the problem of uneven coating in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform release paper coating production equipment, comprising a housing, with paper tape inlets and outlets at both ends of the housing, guide rollers rotatably mounted at the paper tape inlets and outlets inside the housing, a scraper plate fixedly mounted inside the housing, and a coating mechanism on the housing. The coating mechanism includes a coating tube movably mounted inside the housing and an installation sleeve fixedly mounted outside the housing. A rotating column is rotatably mounted inside the installation sleeve, a movable shaft is fixedly mounted on the rotating column, a telescopic sleeve is slidably mounted inside the installation sleeve, a telescopic rod is fixedly mounted on the telescopic sleeve, a telescopic frame is fixedly mounted on the telescopic rod, and one end of the coating tube is fixedly mounted on the telescopic frame. A drive mechanism is provided on one side of the movable shaft.

[0006] Preferably, the rotating column is provided with a reciprocating groove, and a sliding support is fixedly installed on the inner wall of the mounting sleeve, and the sliding support is slidably installed in the reciprocating groove.

[0007] Preferably, the equipment housing has a sliding groove, the coating tube is slidably installed inside the equipment housing through the sliding groove, and a feeding pipe is connected to the coating tube.

[0008] Preferably, the rotating column is rotatably installed in the mounting sleeve via a movable shaft, and the telescopic sliding sleeve is slidably installed in the mounting sleeve via a telescopic rod. One end of the telescopic rod is fixedly installed on the telescopic sliding sleeve, and the other end of the telescopic rod is fixedly installed on the telescopic frame.

[0009] Preferably, the drive mechanism includes a drive motor fixedly installed on one side of the equipment housing and a recovery pipe fixedly installed on the bottom of the equipment housing. A liquid pump is fixedly installed on the recovery pipe. A drive shaft is fixedly installed at the output end of the drive motor. A transmission shaft is provided between the drive shaft and the liquid pump. Helical gears are provided on the drive shaft, the transmission shaft and the movable shaft, and the helical gears mesh together in pairs.

[0010] Preferably, the drive motor is provided with a motor frame, and the drive motor is fixedly installed on one side of the equipment housing via the motor frame.

[0011] Preferably, the output end of the drive motor is provided with a coupling, and the drive shaft is fixedly installed on the output end of the drive motor through the coupling. The bottom of the equipment housing is provided with a recycling port, and the recycling pipe is connected to the bottom of the equipment housing through the recycling port.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this application, after the drive motor is started, it drives the drive shaft to rotate. Subsequently, the rotation of the drive shaft drives the rotation of the movable shaft, which in turn causes the rotating column to rotate. During the rotation of the rotating column, the sliding support slides along the reciprocating groove, causing the telescopic sleeve to perform telescopic movement. The telescopic movement of the telescopic sleeve then drives the coating tube to perform corresponding telescopic actions, ultimately achieving the uniform coating of the coating material onto the surface of the paper tape.

[0014] In this application, as the paper tape moves forward, the scraper plate flattens the coating material. Excess coating material generated during the flattening process falls to the bottom of the equipment casing. At this time, the drive shaft rotates the transmission shaft, which in turn drives the liquid pump to start working, recycling the excess coating material through a recovery pipe, effectively reducing waste.

[0020] 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.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a uniform coating production equipment for release paper, including a housing 1, with paper tape inlet and outlet 2 at both ends of the housing 1, guide rollers 3 rotatably installed at the paper tape inlet and outlet 2 inside the housing 1, a scraper plate 4 fixedly installed inside the housing 1, a coating mechanism 5 on the housing 1, and a drive mechanism 6 on one side of the movable shaft 501. The coating mechanism 5 and the drive mechanism 6 work together to uniformly coat the paper tape surface and can recover excess coating material, reducing waste.

[0022] like Figure 2 and Figure 3As shown, the coating mechanism 5 includes a coating tube 509 movably installed inside the equipment housing 1 and a mounting sleeve 506 fixedly installed on the outside of the equipment housing 1. A rotating column 502 is rotatably installed inside the mounting sleeve 506, and a movable shaft 501 is fixedly installed on the rotating column 502. A telescopic sleeve 504 is slidably installed inside the mounting sleeve 506, and a telescopic rod 507 is fixedly installed on the telescopic sleeve 504. A telescopic frame 508 is fixedly installed on the telescopic rod 507, and one end of the coating tube 509 is fixedly installed on the telescopic frame 508. A reciprocating groove 503 is provided on the rotating column 502. A sliding support foot 505 is fixedly installed on the inner wall of the mounting sleeve 506, and the sliding support foot 505 is slidably installed in the reciprocating groove 503. A sliding groove is provided on the equipment housing 1, and the coating tube 509 is slidably installed inside the equipment housing 1 through the sliding groove. A feeding pipe is connected to the coating tube 509.

[0023] Specifically, when the drive motor 601 is started, it begins to rotate the drive shaft 603. As the drive shaft 603 rotates, the movable shaft 501 also rotates. The rotation of the movable shaft 501, in turn, drives the rotating column 502 to rotate. During the rotation of the rotating column 502, the sliding support 505 slides along the reciprocating groove 503, which causes the telescopic sleeve 504 to extend and retract. Simultaneously, the telescopic sleeve 504 further drives the coating tube 509 to extend and retract accordingly. Ultimately, the extension and retraction of the coating tube 509 ensures that the coating material is evenly coated onto the surface of the paper tape, guaranteeing the uniformity and quality of the coating process.

[0024] like Figure 2 and Figure 4 As shown, the drive mechanism 6 includes a drive motor 601 fixedly installed on one side of the equipment housing 1 and a recovery pipe 606 fixedly installed on the bottom of the equipment housing 1. A liquid pump 605 is fixedly installed on the recovery pipe 606. A drive shaft 603 is fixedly installed at the output end of the drive motor 601. A transmission shaft 604 is provided between the drive shaft 603 and the liquid pump 605. Helical gears 602 are provided on the drive shaft 603, the transmission shaft 604 and the movable shaft 501, and the helical gears 602 mesh together in pairs. A motor frame is provided on the drive motor 601, and the drive motor 601 is fixedly installed on one side of the equipment housing 1 through the motor frame.

[0025] Specifically, as the paper tape moves forward, the scraper plate 4 functions to evenly smooth the coating material. During this process, excess coating material naturally falls to the bottom of the equipment casing 1. Next, the drive shaft 603 begins to function, driving the transmission shaft 604 to rotate. The rotation of the transmission shaft 604 further drives the liquid pump 605 to operate. The operation of the liquid pump 605 allows excess coating material to be effectively recycled through the recovery pipe 606, thus improving material utilization efficiency and significantly reducing resource waste.

[0026] Working principle: During use, the paper tape enters the equipment housing 1 through the paper tape inlet / outlet 2. After the paper tape enters the equipment housing 1, the drive motor 601 can be started. After starting the drive motor 601, it will drive the drive shaft 603 to rotate. After the drive shaft 603 rotates, it will drive the movable shaft 501 to rotate. After the movable shaft 501 rotates, it will drive the rotating column 502 to rotate. During the rotation of the rotating column 502, the sliding support 505 will slide along the reciprocating slide groove 503, causing the telescopic sleeve 504 to extend and retract. After the telescopic sleeve 504 extends and retracts, it will drive the coating tube 509 to extend and retract, thereby evenly coating the coating material onto the surface of the paper tape. Then, control the paper tape to move forward. When the paper tape moves forward, the scraper plate 4 will scrape the coating material flat. The excess coating material generated by scraping will fall to the bottom of the equipment housing 1. At this time, the drive shaft 603 will drive the transmission shaft 604 to rotate. After the transmission shaft 604 rotates, it will drive the liquid pump 605 to operate, thereby recovering the excess coating material through the recovery pipe 606.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
