Description

Technical Field

[0001] The utility model relates to the technical field of PE film processing, in particular to a PE film processing and smoothing device. Background Art

[0002] PE film, also known as polyethylene film, is produced from PE granules. PE film is moisture-resistant and has low water permeability. Depending on the manufacturing method and control measures, polyethylene film can be manufactured into products with varying properties, including low-density, medium-density, high-density polyethylene, and cross-linked polyethylene.

[0003] In the existing technology, PE film is soft and has a certain degree of stretchability, so it will curl due to uneven force on the surface during processing, resulting in wrinkles on the surface of the PE film. The generation of wrinkles will affect the subsequent processing positioning of the PE film, resulting in reduced processing accuracy, affecting the subsequent processing of the PE film, and reducing the quality of the processed products. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a PE film processing and smoothing device so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A PE film processing and smoothing device comprises a base, wherein two sides of the top of the base are fixedly connected to support frames, a support assembly is rotatably connected between the two support frames, and a conveying roller is rotatably provided at one end of the support assembly;

[0007] The end of the support assembly away from the conveying roller is fixedly connected to a cross bar, and two smoothing rods are symmetrically installed in the middle of the side of the cross bar away from the conveying roller. The ends of the two smoothing rods away from the cross bar are respectively fixedly connected to the two sides of the end of the support assembly, and the bottom of the smoothing rod is rotatably connected to the smoothing roller.

[0008] Furthermore, the support assembly includes a support shaft, a support plate and a support rod, the two ends of the support shaft are respectively rotatably connected to the two support frames, the two ends of the support shaft are rotatably connected to the support plates, and the top of the support plate is fixedly connected to the support rod.

[0009] Furthermore, the connection between the support plate and the support rod is located at one-third of the length of the support rod, so that the support rod is divided into a long rod and a short rod;

[0010] The conveying roller is arranged at the end of the short rod;

[0011] The cross bar is installed on one side of the long rod close to the end portion, and one end of the smoothing rod away from the cross bar is fixedly connected to the end portion of the long rod.

[0012] Furthermore, a limit block for holding the support rod is fixedly connected to the inner side wall of the support frame, and the limit block is located below the long rod.

[0013] Furthermore, the outer circumference of the smoothing roller is covered with a rubber sleeve for increasing friction, and the end of the smoothing roller is processed with a rounded corner.

[0014] Furthermore, an electric heating block is embedded in the bottom of the cross bar, and a temperature sensor is fixedly connected to the bottom of the cross bar on one side of the electric heating block.

[0015] In summary, the present invention has at least one of the following beneficial technical effects:

[0016] 1. This PE film processing and smoothing device uses an inclined smoothing rod and smoothing roller. When the PE film is conveyed, the rotation of the smoothing roller applies a lateral traction force to the PE film, causing the PE film to stretch under the action of the traction force, thereby smoothing the PE film.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 5 The utility model discloses a PE film processing and smoothing device, comprising a base 1, with support frames 2 fixedly connected to both sides of the top of the base 1, a support assembly 3 rotatably connected between the two support frames 2, and a conveying roller 4 rotatably provided at one end of the support assembly 3;

[0028] The end of the support assembly 3 away from the conveying roller 4 is fixedly connected to a cross bar 5, and two smoothing rods 6 are symmetrically installed in the middle of the side of the cross bar 5 away from the conveying roller 4. The ends of the two smoothing rods 6 away from the cross bar 5 are respectively fixedly connected to the two sides of the end of the support assembly 3, and the bottom of the smoothing rod 6 is rotatably connected to a smoothing roller 7.

[0029] In this embodiment, since the PE film itself is soft and has a certain degree of stretchability, it is very easy to wrinkle during production, causing the subsequent processing positioning points to shift, affecting the subsequent processing accuracy, and thus reducing the product quality of the PE film.

[0030] Therefore, observe Figure 1 and Figure 2 It can be found that support frames 2 are installed on both sides of the top of the base 1, and a cross bar 5 is connected between the two support frames 2 through a support assembly 3. At the same time, a smoothing rod 6 is symmetrically installed in the middle of the cross bar 5, and the ends of the two smoothing rods 6 are respectively connected to the two ends on the same side of the support assembly 3, so that the smoothing roller 7 at the bottom of the smoothing rod 6 is tilted, so that the smoothing roller 7 can apply a lateral traction force to the PE film when rolling, so that the PE film can be transported as shown in FIG. Figure 3 As shown, it is opened by the traction force applied by the smoothing roller 7, so as to smooth the PE film.

[0031] Since the wrinkles of the PE film are caused by uneven surface force, the PE film will shrink again after the two smoothing rollers 7 smooth the PE film for a short time. Figure 1 and Figure 2 It can be found that the side of the support component 3 away from the smoothing roller 7 is rotatably connected to the conveying roller 4, and the PE film passes through the bottom of the smoothing roller 7 and the top of the conveying roller 4 in turn, so that the PE film is pressed down by the smoothing roller 7 and the top of the conveying roller 4 during transportation, so that the smoothing roller 7 and the conveying roller 4 exert a tensioning effect on the PE film, so that the PE film is pulled and tightened after being smoothed, which can effectively prevent the PE film from shrinking in a naturally relaxed state, and further improve the smoothing effect of the smoothing device on the PE film.

[0032] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the support assembly 3 includes a support shaft 31, a support plate 32 and a support rod 33. The two ends of the support shaft 31 are respectively rotatably connected to the two support frames 2. Both ends of the support shaft 31 are rotatably connected to the support plates 32. The top of the support plate 32 is fixedly connected to the support rod 33.

[0033] The connection between the support plate 32 and the support rod 33 is located at one-third of the length of the support rod 33, so that the support rod 33 is divided into a long rod 331 and a short rod 332;

[0034] The conveying roller 4 is arranged at the end of the short rod 332;

[0035] The cross bar 5 is installed on one side of the long rod 331 close to the end thereof, and the end of the smoothing rod 6 away from the cross bar 5 is fixedly connected to the end of the long rod 331;

[0036] A limiting block 8 for holding the supporting rod 33 is fixedly connected to the inner side wall of the supporting frame 2 , and the limiting block 8 is located below the long rod 331 .

[0037] In this embodiment, the support shaft 31 is provided to rotate the support plate 32 connected to the support shaft 31, thereby rotating the support rod 33 connected to the top of the support plate 32, so that the conveying roller 4 and the smoothing roller 7 at both ends of the support rod 33 can freely adjust their positions to change the pressure applied to the PE film, so that the PE film remains taut during the conveying process.

[0038] By making the connection point between the support rod 33 and the support plate 32 at one-third of the length of the support rod 33, the force arm lengths of the conveying roller 4 and the smoothing roller 7 can be made different, so that the support rod 33 is divided into a long rod 331 and a short rod 332 according to the different lengths of the force arm. At the same time, the conveying roller 4 is set at the end of the short rod 332, and the cross bar 5 is installed on the side of the long rod 331 close to the end, and the end of the smoothing rod 6 connected to the middle of the long rod 331 is connected to the end of the long rod 331, so that the force at both ends of the support rod 33 can be made different. By creating a pressure difference at both ends of the support rod 33, one end of the support rod 33 is tilted and the other end is sunk, so that the smoothing roller 7 and the conveying roller 4 exert pressure on the PE film, so that the PE film is automatically tensioned during transportation, to prevent the PE film from loosening and shrinking, thereby ensuring the smoothing effect of the smoothing device.

[0039] In a further preferred embodiment of the present invention, Figure 1 As shown, the outer circumference of the smoothing roller 7 is covered with a rubber sleeve 9 for increasing friction, and the end of the smoothing roller 7 is processed with a rounded corner.

[0040] In this embodiment, in order to reduce the damage of the PE film during transportation, the surface of the smoothing roller 7 is usually set to be smooth to prevent the PE film from being scratched during transportation. However, the smooth smoothing roller 7 will lead to insufficient friction with the PE film and cannot rotate, thereby affecting the smoothing effect of the smoothing roller 7 on the PE film. Figure 1 It can be found that a rubber sleeve 9 is provided on the outer wall of the smoothing roller 7, and the flexible contact of the rubber sleeve 9 is used to reduce the damage to the PE film. At the same time, the larger friction coefficient of the rubber sleeve 9 can greatly improve the friction with the PE film, so that the PE film can rotate with the smoothing roller 7 when it moves. The rotation of the smoothing roller 7 is used to apply lateral traction to the PE film, which can effectively ensure the smoothing effect of the PE film.

[0041] Since the PE film is also pressed down by the smoothing roller 7 when being smoothed, the end of the smoothing roller 7 will squeeze the PE film, causing the surface of the PE film to be subjected to excessive pressure, which will cause the film surface of the PE film to be damaged. Therefore, the two ends of the smoothing roller 7 are processed with rounded corners. The rounded corners can prevent the PE film from being damaged when being pressed down by the smoothing roller 7, thereby further improving the quality of the PE film.

[0042] In a further preferred embodiment of the present invention, Figure 5 As shown, an electric heating block 10 is embedded in the bottom of the cross bar 5 , and a temperature sensor 11 is fixedly connected to one side of the electric heating block 10 at the bottom of the cross bar 5 .

[0043] In this embodiment, the electric heating block 10 can heat the PE film after it is smoothed, so that the surface of the PE film is heated to change the internal stress, so that the PE film will not shrink after cooling and shaping, which can further improve the smoothing effect of the PE film.

[0044] The temperature sensor 11 is used to monitor the temperature of the electric heating block 10 in real time to prevent the temperature of the electric heating block 10 from being too high and causing the PE film to be melted or the temperature of the electric heating block 10 from being too low and unable to reshape the PE film, thereby effectively improving the practicality of the electric heating block 10.

[0045] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
