Description

Technical Field

[0001] This utility model belongs to the field of reflective film production and application technology, specifically relating to an adjustable winding device for multi-size reflective films. Background Technology

[0002] Reflective film is a retroreflective material that has been made into a thin film and can be applied directly. It is made using glass bead technology, microprism technology, synthetic resin technology, thin film technology, coating technology, and micro-replication technology.

[0003] According to the search: (1) Patent No. / Application No. 202222217066.9 discloses a reflective film winding device, including a support frame, a traction roller and a dust collection frame are mounted on the inner wall of the support frame, a brush and a suction hole are provided on the inner wall of the dust collection frame, an air pipe is embedded on the end face of the dust collection frame, a dust collection box and a lifting base are installed at the bottom of the support frame, a fan and an air filter are installed inside the dust collection box, a lifting rod is installed vertically at the top of the lifting base, a sliding frame is installed at the top of the lifting rod, one side of the sliding frame is engaged with the support frame, a rotary motor is mounted on the side of the sliding frame, a rotating shaft is embedded inside the frame of the sliding frame, a winding roller is engaged inside the rotating shaft, and a pressure cap is engaged at the top of the rotating shaft. This reflective film winding device moves up and down reciprocally under the drive of a lifting rod, enabling the winding roller to be adjusted up and down. This not only facilitates adjusting the height of the winding roller according to the film material, but also facilitates the disassembly of the rolled film material later, avoiding problems such as falling and injuring personnel or damaging the film material.

[0004] Analysis revealed that the winding roller in the above technical solution can only wind up reflective film of a specific single width. When winding up reflective film with a narrower width, there is no corresponding reflective film limiting and guiding structure design, which may lead to winding deviation. This can easily cause the reflective film to be scrapped and wasted, increasing production costs.

[0005] Therefore, based on the above problems, this utility model provides a winding device suitable for the production of road reflective film. Utility Model Content

[0020] Example 1

[0021] like Figure 1 and Figure 2 The adjustable rewinding device for multi-size reflective film shown includes a horizontal frame base 100 and a strip plate 101.

[0022] One end face of the transverse frame base 100 is symmetrically provided with a guide shaft mounting bearing seat 102.

[0023] A guide shaft 103 is provided on the guide shaft mounting bearing housing 102.

[0024] The guide shaft 103 is provided with guide shaft locking parts 104 at both ends.

[0025] The guide shaft 103 is symmetrically provided with external threaded adjusting sleeves 105 at both ends.

[0026] Adjusting nuts 106 are respectively provided on the external thread adjusting sleeve 105.

[0027] A circular hollow baffle 107 is fixedly provided on one side of the adjusting nut 106.

[0028] A circular hollow guide sleeve 108 is fixedly provided on one side of the circular hollow baffle 107.

[0029] One end face of the strip-shaped platform 101 is equipped with a power motor 109 and a gearbox 110 for use in conjunction with it.

[0030] The strip-shaped platform 101 has symmetrically arranged receiving shaft mounting bearing seats 111 at both ends.

[0031] Transition shafts 113 are respectively installed on the receiving shaft mounting bearing housing 111.

[0032] Each transition shaft 113 is provided with a transition shaft locking part 112.

[0033] A take-up shaft 118 is provided on the opposite side of the transition shaft 113;

[0034] One end of the arbitrary transition shaft 113 is connected to the gearbox 110.

[0035] The working principle is as follows:

[0036] Before winding, adjust the adjusting nut 106 relative to or opposite to the width of the reflective film. The adjusting nut 106 rotates with the external thread adjusting sleeve 105 as the rotation center, driving the circular hollow baffle 107 and the circular hollow guide sleeve 108 to move horizontally relative to or opposite to each other until they meet the guide width of the reflective film.

[0037] During winding, the reflective film winding drum (not shown in the figure, but it does not affect the disclosure of the technical solution of this application) is first put on the winding shaft 118. Then, one end of the reflective film is introduced into the reflective film winding drum from below the circular hollow guide sleeve 108 (the two sides of the reflective film are located between the circular hollow baffles 107). Finally, the power motor 109 is started to drive the transition shaft 113 to rotate through the gearbox 110. At this time, the transition shaft 113, together with the winding shaft 118 and the reflective film winding drum, rotates to complete the winding of the reflective film.

[0038] Example 2

[0039] Based on Example 1, such as Figure 3 The multi-size adjustable rewinding device for reflective film shown in a and 3b further includes a circular seat 114 disposed on the opposite side of the transition shaft 113, a U-shaped slot 115 disposed on the opposite side of the circular seat 114, a circular seat screw groove 1141 disposed on the opposite side of the circular seat 114 and located below the U-shaped slot 115, a fixing block 116 disposed on the end faces of both ends of the rewind shaft 118, a fixing block screw hole 1161 disposed in the fixing block 116, and a bolt 117 for fixing the fixing block 116 and the circular seat 114 through the fixing block screw hole 1161 and the circular seat screw groove 1141; wherein the fixing block 116 is inserted into the circular seat 114 through the U-shaped slot 115.

[0040] With the above design structure, after the reflective film take-up cylinder on the take-up shaft 118 has finished its winding operation, it is easy to replace the reflective film take-up cylinder. That is, after unscrewing the bolt 117, the whole thing can be lifted up. At this time, the fixing block 116 will disengage from the U-shaped slot 115 on the circular seat 114, thus completing the removal of the reflective film take-up cylinder (which is the cylinder with the reflective film) from the take-up shaft 118.

[0041] Example 3

[0042] Based on Embodiment 1 or Embodiment 2, the multi-size reflective film adjustable winding device further includes tension shaft mounting bearing seats 119 symmetrically arranged on the other end face of the horizontal frame base 100, tension shafts 120 respectively arranged on the tension shaft mounting bearing seats 119, tension shaft locking parts 121 respectively arranged at both ends of the tension shafts 120, and tension guide cylinders 122 arranged on the tension shafts 120;

[0043] The reflective film is introduced from above the tensioning guide tube 122, which ensures that the reflective film has a certain tension when it enters the circular hollow baffle 107, and ensures that the reflective film winding tube on the winding shaft 118 completes stable winding.

[0044] In addition, preferably as follows Figure 4 The guide shaft mounting bearing seat 102, the take-up shaft mounting bearing seat 111, and the tensioning shaft mounting bearing seat 119 are arranged in a triangle, so that the introduced reflective film to be wound has the corresponding winding tension.

[0045] The guide shaft mounting bearing 102, power motor 109, gearbox 110, take-up shaft mounting bearing 111, and tension shaft mounting bearing 119 in the multi-size adjustable rewinding device of this structure are all conventional components. They will not be described in detail in this application.

[0047] 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.
