Description

Technical Field

[0001] The utility model belongs to the technical field of reflective film production, in particular to an automatic strip cutting device for reflective film. Background Art

[0002] Retroreflective film is a direct-applied retroreflective material made using glass bead technology, microprism technology, synthetic resin technology, film technology, coating technology and micro-replication technology.

[0003] During the production process, the reflective film needs to be cut. For example, the existing public patent (publication number CN220680868U) discloses a stripping device for the production of reflective film, including a workbench, the upper surface of the workbench is fixedly connected with an L-shaped plate, the upper surface of the L-shaped plate is fixedly connected with an electric push rod, the telescopic end of the electric push rod is fixedly connected with a concave plate, the inner wall of the concave plate is fixedly connected with a sleeve, the surface of the sleeve is fixedly connected with a first mounting ring, and the inner wall of the sleeve is rotatably connected with a rotating rod. In the utility model, the electric push rod is started, the electric push rod drives the concave plate to move downward, and the cutting knife moves downward. When the reflective film moves to the cutting knife, the reflective film can be cut. When cutting another size, the T-shaped plug rod can be pulled out of the countersunk hole, the rotating mounting plate drives the rotating rod to rotate, and the rotating rod drives the second mounting ring to rotate, so that a part of the cutting knife is rotated and stored, so that the distance between adjacent cutting knives is changed, and stripping of two sizes can be achieved.

[0004] The functionality of the above-mentioned stripping device is relatively low. During the stripping process, the conveying and guiding of the reflective film require the assistance of an external structure, resulting in low overall practicality. To this end, we provide a reflective film automatic stripping and cutting device to solve the above-mentioned problems. Utility Model Content

[0022] Example

[0023] See also Figure 1-3 The utility model is a reflective film automatic strip cutting device, comprising a casing 14; a bracket 8 is fixed to the bottom of the side of the casing 14, a mounting seat 9 is fixed to the end of the bracket 8, and a reflective film roller 12 is movably connected to the notch of the mounting seat 9 via an axle rod, and a reflective film body 1 is wrapped around the surface of the reflective film roller 12, and the reflective film body 1 is sequentially penetrated by a guide roller 2, a transmission roller 3 and a positioning roller 7, and the transmission roller 3 is connected to a driving roller 4 via a transmission gear member 6, and a cutting disc 5 is equidistantly fixed to the circumference of the driving roller 4, and a bearing sleeve is arranged on the outside of the driving roller 4, and the bearing sleeve is embedded in the notch of the upper part of the casing 14, and the bearing sleeve is connected to the piston end of the cylinder 10, and the cylinder 10 is fixed to the upper side of the casing 14.

[0024] Specifically, in the reflective film automatic strip cutting device involved in the present application, a lifting and adjustable driving roller 4 is provided to drive the cutting disc 5 to strip the reflective film body 1, so as to facilitate the adjustment of the cutting thickness of the reflective film body 1, thereby being suitable for the strip cutting of reflective film bodies 1 of different thicknesses. The cutting device is combined with a reflective film winding roller 12, a guide roller 2, a transmission roller 3 and a positioning roller 7 to realize the feeding, guiding, conveying and cutting of the reflective film body 1 in one. The overall structure is compact, occupies a small space, operates with low power consumption, and has great practical value.

[0025] Further description of the above structure is as follows:

[0026] A support foot 15 is fixed at the bottom of the housing 14, and the support foot 15 has a built-in damping buffer; a tightening knob 11 is arranged above the mounting seat 9, and the inner end of the tightening knob 11 is fixed to the shaft connected to the end of the reflective film roller 12.

[0027] Specifically, the support foot 15 is used for the overall support of the device, and its built-in buffer damper is a currently more common shock-absorbing structure, which is used for the operation buffer of the device. Its specific structure is not described in detail here. The tightening knob 11 realizes the installation and positioning of the reflective film roller 12 and the mounting seat 9 by interfering with the shaft member. The reflective film roller 12 is movably connected to the shaft member connected to its end. Therefore, the reflective film roller 12 rotates under the action of external force and is used for strip cutting and feeding of the reflective film body 1.

[0028] An extension plate 13 is integrally arranged above the bracket 8, and the end of the guide roller 2 is movably arranged in the extension plate 13 and the inside of the casing 14 via a shaft; the ends of the transmission roller 3 and the positioning roller 7 are movably connected to the inner wall of the casing 14 via a shaft, and the side of the transmission roller 3 is evenly and continuously provided with stripes.

[0029] Specifically, the extension plate 13 is used for the movable installation of part of the guide rollers 2, and the ends of the remaining guide rollers 2 are movably connected to the inner wall of the housing 14 via shafts. Under the linkage of several guide rollers 2, the conveying track of the reflective film body 1 is fixed, and the conveying is relatively stable;

[0030] The driving roller 3 and the positioning roller 7 are also movably connected to the inner wall of the housing 14. The stripes arranged on the surface of the driving roller 3 are used to increase the friction damping of the reflective film body 1 to prevent the reflective film body 1 from slipping during the transportation process, while the positioning roller 7 is used for directional transportation of the reflective film body 1 after strip cutting to prevent the reflective film body 1 after strip cutting from being disordered due to uneven force during the transportation process.

[0031] The cutting disc 5 is perpendicular to the conveying direction of the reflective film body 1 , and the outer ring of the cutting disc 5 moves relative to the inner ring sleeve thereof.

[0032] Specifically, the cutting disc 5 is divided into an inner ring and an outer ring structure, wherein the inner ring is fixed to the driving roller 4, and the outer ring is a cutting surface, which contacts and fits with the reflective film body 1 during the cutting process to achieve strip cutting of the reflective film body 1. At the same time, under the friction damping of the reflective film body 1, the inner ring of the cutting disc 5 rotates relative to the inner ring to assist in the transportation of the reflective film body 1. After the inner and outer rings are fixed, the cutting surface rotates with the rotation of the inner ring, which can also achieve the cutting and transportation of the reflective film body 1. The latter has relatively high operating efficiency, but it will also cause the stability of the reflective film body 1 to be reduced during the cutting and transportation process. Therefore, in actual use, the installation method of the inner and outer rings of the cutting disc 5 is determined according to the cutting requirements.
