Description

Technical Field

[0001] The utility model relates to the technical field of glass coating equipment, in particular to a glass film roll constant tension component. Background Art

[0002] After the glass is produced and processed, it is necessary to coat the upper and lower surfaces of the glass with a protective film to prevent the surface of the glass from being scratched during transportation, packaging, installation, etc. The glass coating machine coats the glass in the process of passing through the glass conveying mechanism, the glass coating mechanism, the film cutting mechanism, and the glass conveying mechanism in sequence to finally complete the glass coating. During the coating process, a film roll is needed to provide the coating raw material, and the film roll needs to ensure the transportation stability and reliability of the film roll during the film feeding process to ensure the stability of the glass coating treatment, and during the coating process, the film roll roller needs to stop rotating in time according to production requirements, which requires the film roll roller to have better rotation controllability. Therefore, a glass film roll constant tension component is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a glass film roll constant tension assembly for solving the problem of the controllability of the rotation of the film roll roller in the prior art.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] A glass film roll constant tension component, comprising:

[0006] Roller frames, wherein the roller frames are symmetrically arranged in two groups, and a film winding roller is arranged between the two groups of symmetrically arranged roller frames;

[0007] A tension assembly, wherein the tension assembly is arranged on two sets of roller frames and is used to support a film roll. The tension assembly includes a tension base arranged on the inner side of the roller frame, the tension base is axially slidably connected with a tension slide column, a tension rod is hinged between the tension slide column and the tension base, a support roller rod is hinged between the tension slide column and the tension rod of the tension base, and the outer wall of the support roller rod supports the inner wall of the film roll.

[0008] To implement the above technical scheme, the film roll is supported by two groups of symmetrically arranged roller frames, and the rotation of the film roll is controlled by the tension assembly, so as to meet the actual use needs in the coating process and achieve the control of the start and stop action of the film roll. The distance between the tension slide column and the tension base is adjusted by the action of the tension slide column axially slidingly connected on the tension base, thereby driving the action of each hinged tension rod between the tension slide column and the tension base, so that the spacing between the tension rods is increased or decreased, and support roller rods are hinged between the tension rods. When the spacing between the tension rods increases, the height of the support roller rods can be lowered to relax the supporting force on the film roll. When the spacing between the tension rods decreases, the height of the support roller rods can be increased, thereby tightening the inner wall of the film roll, increasing the friction between the support roller rod and the inner wall of the tight film roll, and limiting the rotation of the film roll.

[0009] In one embodiment of the utility model, the tension rods are grouped into two, and two groups of support rods are arranged between the two groups of tension rods. The support rods penetrate the support roller rods at the places where the tension rods are hinged to the support roller rods, and the support rods are hinged to the support roller rods.

[0010] To implement the above technical solution, two tension rods are grouped together, which can improve the support stability of the tension rod, while the support rod can facilitate the connection between the tension rod and the support roller rod.

[0011] In one embodiment of the utility model, the supporting roller rod is cylindrical, and the radial dimensions of both ends of the supporting roller rod gradually decrease. The side portion of the supporting roller rod connected between the two groups of tension rods is flat.

[0012] To implement the above technical solution, the support roller rod is set to be columnar, which can improve its supporting stability, and the radial dimensions of both ends of the support roller rod are gradually reduced, which can improve the convenience of connection between the support roller rod and the tension rod. The part of the side of the support roller rod connected between the two groups of tension rods is set as a plane, which can facilitate sliding cooperation with the tension rod.

[0013] In one embodiment of the present invention, the length of the portions of the two ends of the support roller rod extending between the two sets of tension rods is shorter than the spacing between the two sets of support rods.

[0014] To implement the above technical solution, the length of the parts of the two ends of the support roller rod extending between the two groups of tension rods is shorter than the spacing between the two groups of support rods, which can avoid the support roller rod colliding with the support rod during rotation, causing the rotation of the support roller rod to be affected.

[0015] In one embodiment of the utility model, a tension driving member is arranged on the roller frame, a slide guide base is arranged inside the tension slide, the slide guide base is arranged at the movable end of the tension driving member, and the tension driving member drives the slide guide base to slide along the axial direction of the film roller.

[0016] To implement the above technical solution, by providing a slide guide base in cooperation with a tension driving member, the stability of the tension slide along the axial direction of the film roll can be improved.

[0017] In one embodiment of the present invention, the tension rods are circumferentially arranged in multiple groups on the tension slide and the tension base.

[0018] By implementing the above technical solution, multiple groups of tension rods can improve the support stability and support reliability of the film roll.

[0019] As described above, a constant tension assembly for a glass film roll of the utility model has the following beneficial effects: the film roll is supported by two groups of symmetrically arranged roller frames, and the rotation of the film roll is controlled by the tension assembly, so as to meet the actual use needs in the coating process and achieve the control of the start and stop action of the film roll, and the distance between the tension slide column and the tension base is adjusted by the action of the tension slide column axially slidably connected on the tension base, thereby driving the action of each hinged tension rod between the tension slide column and the tension base, so that the spacing between the tension rods is increased or decreased, and support roller rods are hinged between the tension rods. When the spacing between the tension rods increases, the height of the support roller rods can be lowered to relax the supporting force on the film roll, and when the spacing between the tension rods decreases, the height of the support roller rods can be raised, thereby tightening the inner wall of the film roll, increasing the friction between the support roller rod and the inner wall of the tight film roll, and limiting the rotation of the film roll.

[0025] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0026] See also Figures 1 to 3 The utility model provides a constant tension component for a glass film roll, comprising two groups of symmetrically arranged roller frames 1, a film roll 2 is arranged between the two groups of symmetrically arranged roller frames 1, a tension component is arranged on the two groups of roller frames 1, and is used to support the film roll 2, the tension component comprises a tension base 3 arranged on the inner side of the roller frame 1, a tension slide column 4 is axially slidably connected to the tension base 3, a tension rod 5 is hinged between the tension slide column 4 and the tension base 3, a support roller rod 6 is hinged between the tension slide column 4 and the tension rod 5 using the tension base 3, and the outer wall of the support roller rod 6 supports the inner wall of the film roll 2.

[0027] The film roll 2 is supported by two groups of symmetrically arranged roller frames 1, and the rotation of the film roll 2 is controlled by the tension component, so as to meet the actual use needs in the coating process and achieve the control of the start and stop action of the film roll 2. The tension slide column 4 axially slidably connected to the tension base 3 is actuated to adjust the distance between the tension slide column 4 and the tension base 3, thereby driving the tension rods 5 hinged between the tension slide column 4 and the tension base 3 to move, so that the spacing between the tension rods 5 increases or decreases, and the tension rods 5 are hinged with support roller rods 6. When the spacing between the tension rods 5 increases, the height of the support roller rods 6 can be lowered to relax the supporting force on the film roll 2. When the spacing between the tension rods 5 decreases, the height of the support roller rods 6 can be raised, thereby tightening the inner wall of the film roll 2, increasing the friction between the support roller rods 6 and the inner wall of the tight film roll 2, and limiting the rotation of the film roll 2.

[0028] The tension rods 5 are grouped into two, and two groups of support rods 7 are arranged between the two groups of tension rods 5. The support rods 7 penetrate the support roller rods 6 at the place where the tension rods 5 are hinged to the support roller rods 6, and the support rods 7 are hinged to the support roller rods 6. Grouping the tension rods 5 into two can improve the supporting stability of the tension rods 5, and the support rods 7 can facilitate the connection between the tension rods 5 and the support roller rods 6.

[0029] The support roller rod 6 is set in a columnar shape, and the radial dimensions of both ends of the support roller rod 6 gradually decrease. The part of the side of the support roller rod 6 connected between the two groups of tension rods 5 is set in a plane. Setting the support roller rod 6 in a columnar shape can improve its supporting stability, and the radial dimensions of both ends of the support roller rod 6 gradually decrease, which can improve the convenience of connection between the support roller rod 6 and the tension rod 5. The part of the side of the support roller rod 6 connected between the two groups of tension rods 5 is set in a plane, which can facilitate sliding cooperation with the tension rod 5.

[0030] The length of the part where the two ends of the support roller rod 6 extend between the two groups of tension rods 5 is shorter than the spacing between the two groups of support rods 7. The length of the part where the two ends of the support roller rod 6 extend between the two groups of tension rods 5 is shorter than the spacing between the two groups of support rods 7. This can avoid the support roller rod 6 from colliding with the support rods 7 during rotation, which would affect the rotation of the support roller rod 6.

[0031] A tension driving component 8 is arranged on the roller frame 1, and a slide guide base 9 is arranged inside the tension slide column 4. The slide guide base 9 is arranged at the movable end of the tension driving component 8, and the tension driving component 8 drives the slide guide base 9 to slide axially along the film roll 2. By arranging the slide guide base 9 in conjunction with the tension driving component 8, the stability of the tension slide column 4 sliding axially along the film roll 2 can be improved.

[0032] Multiple groups of tension rods 5 are circumferentially arranged on the tension slide and the tension base 3 . The multiple groups of tension rods 5 can improve the support stability and support reliability of the film roll 2 .

[0033] The utility model supports the film roll by two groups of symmetrically arranged roller frames and controls the rotation of the film roll by using the tension assembly, thereby meeting the actual use needs in the coating process and achieving the control of the start and stop action of the film roll. The distance between the tension slide column and the tension base is adjusted by the action of the tension slide column axially slidably connected to the tension base, thereby driving the action of each hinged tension rod between the tension slide column and the tension base, so that the spacing between the tension rods is increased or decreased. Support roller rods are hinged between the tension rods. When the spacing between the tension rods is increased, the height of the support roller rods can be lowered to relax the supporting force on the film roll. When the spacing between the tension rods is reduced, the height of the support roller rods can be raised, thereby tightening the inner wall of the film roll, increasing the friction between the support roller rod and the inner wall of the tight film roll, and limiting the rotation of the film roll.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
