Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, and in particular to a plastic film calendering machine. Background Technology

[0002] A calender is a machine that compacts and stretches mixed rubber or plastic. It is a basic piece of equipment in the processing of rubber and plastic products. During calendering, rollers arranged in a certain pattern are used at a certain temperature to press and stretch the plastic into a sheet of a certain thickness and surface shape. In the production of plastic film, a calender is usually used to calender the film to make its surface smoother, coated, or softened for easier use later.

[0003] For example, Chinese Patent Publication No. CN219213846U discloses a plastic film calendering machine, including a base, a motor mounted on the base, a guide block welded to the motor, a rotating shaft movably connected to the base, a pressure roller welded to the rotating shaft, the pressure roller contacting the base, a scraping mechanism on the base, and an adjustment mechanism on the pressure roller. This invention, through the use of a cover, screw, scraper, guide rod, spring, and other structures, uses a rotating screw to press the scraper against the pressure roller. As the pressure roller rotates and calenders the film, it scrapes against the roller, preventing impurities from adhering to it and affecting the film calendering quality.

[0004] The above application still has shortcomings. In the above application, impurities on the surface of the pressure roller are scraped off by a scraper to avoid the impurities attached to the pressure roller affecting the calendering quality of the film. However, the plastic film is exposed to the external environment during the transportation process, and it is difficult to remove the impurities adhering to the side of the plastic film. The impurities can easily damage the surface of the pressure roller and reduce the calendering quality of the plastic film.

[0005] Therefore, it is necessary to provide a plastic film calender to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a plastic film calender to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A plastic film calendering machine includes a frame. Two calendering rollers that cooperate with each other to calender plastic films are rotatably connected to the side wall of the frame. Gears are fixed to the same side ends of the two calendering rollers, and the two gears mesh with each other. A drive motor that drives one of the calendering rollers is fixed to the outer side wall of the frame. An inner connector located on one side of the calendering roller is fixed to the inner side wall of the frame. A second slot is provided through the side of the inner connector. A cleaning component for removing impurities from the film surface is provided in the second slot. An adjustment component for adjusting the cleaning component is provided in the inner connector.

[0008] As a further embodiment of this utility model, the cleaning component includes an internal plate disposed in the second slot. There are two internal plates that are symmetrically distributed. A first cavity is opened inside the internal plate. A suction hole communicating with the first cavity is opened on the side of the internal plate facing the center of the inner seat. There are multiple suction holes that are equidistantly distributed. A suction tube is connected to the first cavity.

[0009] As a further embodiment of this utility model, densely distributed soft bristles are fixed on the sides of the two built-in plates that are close to each other.

[0010] As a further embodiment of this utility model, the adjustment component includes a rubber plate disposed inside the inner connector and located on the side of the built-in plate away from the center of the inner connector, and the rubber plate has a second cavity inside.

[0011] As a further embodiment of this utility model, a U-shaped tube is fixed on the inner connector, and the two ends of the U-shaped tube are respectively connected to the interior of two rubber plates, and an infusion tube is connected to the U-shaped tube.

[0012] As a further embodiment of this utility model, a cover is fixed on the inner side wall of the frame, and a first slot is provided at both ends of the cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the plastic film passes through the inner receiving seat, a cleaning component inside the inner receiving seat sucks away dust and other impurities adhering to both sides of the plastic film. Thus, before the plastic film is calendered by the calendering roller, the cleaning component removes impurities from the surface of the plastic film, preventing the adhering impurities from affecting the calendering quality of the film and preventing impurities from damaging the surface of the calendering roller. This ensures the calendering quality of the plastic film and extends the service life of the calendering roller. Compared with the existing technology of blowing away impurities, this utility model removes impurities by sucking them away, avoiding the problem of impurities scattering and causing secondary pollution to the plastic film, and effectively improving the overall impurity removal effect of the plastic film.

[0015] 2. A certain amount of liquid is delivered synchronously to the inside of the two rubber plates through the infusion tube and the U-shaped tube, which causes the rubber plates to expand elastically. The two elastically expanded rubber plates push the two built-in plates to move closer and adjust the distance between the two built-in plates, thereby ensuring that the cleaning component can achieve the best cleaning effect on the sides of plastic films of different sizes.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-5 This utility model provides a plastic film calender, including a frame 3. Two calendering rollers 9 are rotatably connected to the side wall of the frame 3 to cooperate in calendering the plastic film. Gears 4 are fixed on the same side of the two calendering rollers 9, and the two gears 4 mesh with each other. A drive motor 8 is fixed on the outer side wall of the frame 3 to drive one of the calendering rollers 9 to rotate. An inner receiving seat 10 located on one side of the calendering roller 9 is fixed on the inner side wall of the frame 3. A second slot 11 is opened through the side of the inner receiving seat 10. A cleaning component 1 for removing impurities from the film surface is provided in the second slot 11. An adjusting component 2 for adjusting the cleaning component 1 is provided in the inner receiving seat 10. In use, the plastic film is moved and conveyed by a take-up roller or a pull roller. During this process, the plastic film passes through the inner receiving seat 10 and then through the two calendering rollers 9. The drive motor 8 drives one of the calendering rollers 9 to rotate. The calendering roller 9 rotates, thereby driving the two calendering rollers 9 to rotate synchronously in opposite directions through the cooperation of two gears 4. The plastic film is calendered by the two calendering rollers 9. When the plastic film passes through the inner receiving seat 10, the cleaning component 1 set inside the inner receiving seat 10 sucks away the dust and other impurities adhering to both sides of the plastic film. Thus, before the plastic film is calendered by the calendering rollers 9, the cleaning component 1 removes the impurities on the surface of the plastic film, avoiding the adhering impurities from affecting the calendering quality of the film and avoiding the impurities from damaging the surface of the rollers. This ensures the calendering quality of the plastic film and extends the service life of the calendering rollers 9. Moreover, compared with the existing technology of blowing away impurities, this utility model removes impurities by sucking them away, avoiding the problem of impurities scattering and causing secondary pollution to the plastic film, and effectively improving the overall impurity removal effect of the plastic film.

[0026] Further as Figure 3 , Figure 4 and Figure 5As shown, it is worth noting that the cleaning component 1 includes two built-in plates 101 disposed within the second slot 11. The two built-in plates 101 are symmetrically distributed. A first cavity 102 is formed inside each built-in plate 101. Suction holes 103 communicating with the first cavity 102 are formed on the side of each built-in plate 101 facing the center of the inner connector 10. Multiple suction holes 103 are provided and equidistantly distributed. A suction tube 105 is connected to the first cavity 102. A suction pump is externally connected to the suction tube 105. When the plastic film passes through the interior of the inner connector 10, it passes between the two built-in plates 101 and is then suctioned through the suction tube 105, causing the built-in plates 101 to... The internal structure forms a negative pressure suction, thereby sucking away dust and other impurities adhering to both sides of the plastic film through multiple suction holes 103 on the sides of the two built-in plates 101. This removes impurities from the surface of the plastic film before it is calendered by the calendering roller 9, preventing the adhering impurities from affecting the calendering quality of the film and from damaging the surface of the roller. This ensures the calendering quality of the plastic film and extends the service life of the calendering roller 9. Compared with the existing technology of blowing away impurities, this invention removes impurities by suction, avoiding the problem of impurities scattering and causing secondary pollution to the plastic film, and effectively improving the overall impurity removal effect of the plastic film.

[0027] Further as Figure 5 As shown, it is worth noting that densely distributed soft bristles 104 are fixed on the sides of the two built-in plates 101 that are close to each other. When the plastic film passes between the two built-in plates 101, the soft bristles 104 on the sides of the built-in plates 101 come into contact with the sides of the plastic film, thereby brushing the sides of the plastic film with the soft bristles 104 to remove the firmly adhered impurities on the sides of the plastic film. This facilitates the suction hole 103 to thoroughly remove the impurities on the sides of the plastic film, further improving the cleaning effect.

[0028] Further as Figure 5As shown, it is worth noting that the adjustment component 2 includes a rubber plate 201 disposed inside the inner connector 10 and located on the side of the built-in plate 101 away from the center of the inner connector 10. The rubber plate 201 has a second cavity 202 inside. A U-shaped tube 203 is fixed on the inner connector 10. The two ends of the U-shaped tube 203 are respectively connected to the interior of the two rubber plates 201. An infusion tube 205 is connected to the U-shaped tube 203. An infusion pump is connected to the infusion tube 205. When cleaning the sides of plastic films of different thicknesses, a certain amount of liquid is simultaneously delivered to the interior of the two rubber plates 201 through the infusion tube 205 and the U-shaped tube 203, thereby causing the rubber plates 201 to elastically expand. The elastic expansion of the two rubber plates 201 simultaneously pushes the two built-in plates 101 to move closer and closer, thereby adjusting the distance between the two built-in plates 101 and ensuring that the cleaning component 1 can achieve a better cleaning effect on the sides of plastic films of different specifications.

[0029] This solution includes the following working process: The plastic film passes through the inner connector 10 and then through two calendering rollers 9. A drive motor 8 drives one of the calendering rollers 9 to rotate, which in turn drives the two calendering rollers 9 to rotate synchronously in opposite directions via two gears 4. This calendering process calenders the plastic film. As the plastic film passes through the inner connector 10, it passes between two built-in plates 101. A suction pipe 105 creates a negative pressure inside the built-in plates 101, allowing multiple suction holes 103 on the sides of the two built-in plates 101 to remove dust and other impurities adhering to both sides of the plastic film. In addition, before the plastic film is calendered by the calendering roller 9, impurities on the surface of the plastic film are removed. When cleaning the sides of plastic films of different thicknesses, a certain amount of liquid is simultaneously delivered to the inside of the two rubber plates 201 through the infusion pipe 205 and the U-shaped pipe 203, so that the rubber plates 201 will elastically expand. The two elastically expanded rubber plates 201 simultaneously push the two built-in plates 101 to move closer and adjust, thereby adjusting the distance between the two built-in plates 101 and ensuring that the suction hole 103 and the soft bristles 104 can achieve a better cleaning effect on the sides of plastic films of different specifications.

[0030] Further as Figure 1 and Figure 2 As shown, it is worth noting that a cover 6 is fixed on the inner wall of the frame 3, and a first slot 7 is opened at both ends of the cover 6; in actual operation, the cover 6 is used to protect the calendering roller 9 and the inner seat 10.

[0031] In summary: When the plastic film passes through the inner connector 10, the cleaning component 1 inside the inner connector 10 sucks away dust and other impurities adhering to both sides of the plastic film. Thus, before the plastic film is calendered by the calendering roller 9, the cleaning component 1 removes impurities from the surface of the plastic film, preventing the adhering impurities from affecting the calendering quality of the film and preventing impurities from damaging the surface of the roller. This ensures the calendering quality of the plastic film and extends the service life of the calendering roller 9. Moreover, compared with the existing technology of blowing away impurities, this utility model effectively improves the overall impurity removal effect of the plastic film by sucking away impurities, avoiding the problem of impurities scattering and causing secondary pollution to the plastic film.

[0032] The drive motor 8 can be purchased from the market. The drive motor 8 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
