[0036] Referring to Figures 1 to 8 , the rear withdrawal type material roll supplier of the embodiment of the utility model, including the bearing plate 10, the material discharge assembly 20 installed in one end of bearing plate 10, the material stripping assembly 30 installed in one side of material discharge assembly 20, the material taking assembly 40 installed in the side of material stripping assembly 30 away from material discharge assembly 20, the bottom film winding assembly 60 installed in the lower of material stripping assembly 30, and the cover film winding assembly 70 installed in the upper of bottom film winding assembly 60 correspondingly, the cover film winding assembly 70 is located in the upper between material discharge assembly 20 and material stripping assembly 30. Wherein, the material roll applied by the utility model mainly includes bottom film, multiple material pieces attached on the bottom film, and cover film covering the bottom film, the material piece is located between the bottom film and cover film. Generally, the material piece can be label, protective film, foam and the like.

[0037] The material discharge assembly 20 includes the material discharge wheel 21 connected with the bearing plate 10, the material discharge plate 22 installed in one side of the material discharge wheel 21, the lifting cylinder 23 installed in the upper of the material discharge plate 22, and the pressing block 24 installed in the bottom end of the lifting cylinder 23, the pressing block 24 is used for abutting against the semi-finished product to compress the semi-finished product, so as to facilitate the subsequent stripping of the material piece.

[0038] Specifically, the material discharge plate 22 is hollowly arranged, multiple air holes 220 are uniformly and spacedly arranged on one side of the top surface of the material discharge plate 22, the air holes 220 are communicated with the inside of the material discharge plate 22, the bottom surface of the material discharge plate 22 is connected with the vacuum pump (not shown in the figure) through the air connection pipe (not shown in the figure), so that the top surface of the material discharge plate 22 can generate negative pressure, thereby adsorbing the bottom surface of the semi-finished product, facilitating the subsequent stripping of the material piece.

[0039] The material stripping assembly 30 includes the moving plate 31 slidably connected on one side of the bearing plate 10, the material stripping plate 32 installed on the top end of the moving plate 31, the limiting strip 33 movably installed on the opposite sides of the material stripping plate 32, the moving motor 34 installed on the bottom end of the moving plate 31, the gear 35 coaxially connected with the rotor of the moving motor 34, and the rack 36 installed on the bearing plate 10, the rack 36 is matched and engaged with the gear 35, so that the moving motor 34 can drive the moving plate 31 to slide back and forth on the bearing plate 10.

[0040] In the embodiment, the moving plate 31 is slidably connected with the bearing plate 10 through the guide rail pair.

[0041] In the embodiment, the material stripping plate 32 includes the material stripping plate body 321 and the stripping knife 322 hingedly connected on one side of the material stripping plate body 321, the cutting edge of the stripping knife 322 is wedge-shaped.

[0042] The taking assembly 40 comprises a taking plate 41 installed on the side of the stripping plate 32 away from the feeding plate 22, and a plurality of photoelectric sensors 42 installed on the taking plate 41 at intervals.

[0043] The traction assembly 50 comprises a traction motor 51 located below the feeding plate 22, a feeding steel roller 52 installed below the traction motor 51, an adjusting seat 53 movably installed on one side of the feeding steel roller 52, a rubber roller 54 hingedly connected to the adjusting seat 53, and a wrench 55 connected to one side of the rubber roller 54. A space is provided between the rubber roller 54 and the feeding steel roller 52 for the passage of the base film. Under the action of gravity, the rubber roller 54 naturally adheres to the feeding steel roller 52 to clamp the base film. During operation, the traction motor 51 drives the feeding steel roller 52 to rotate synchronously, and the base film is clamped and conveyed between the rubber roller 54 and the feeding steel roller 52, so as to realize the feeding of the base film.

[0044] In the present embodiment, the adjusting seat 53 is movable to control the distance between the adjusting seat 53 and the feeding steel roller 52, thereby adapting to base films of different thicknesses.

[0045] In actual operation, the operator first correctly installs the complete roll of material comprising the base film, the patches and the cover film on the feeding wheel 21. Then, the cover film is separated and wound on the cover film winding assembly 70, leaving the combination of the base film and the patches. The operator manually takes away several patches to form a bare base film section, and then manually pulls this part of the bare base film through the traction assembly 50 and winds it on the base film winding assembly 60. At this point, the pulling of the traction assembly 50 can drive the semi-finished product (i.e. the combination of the base film and the patches) to pass through the feeding plate 22 and the stripping assembly 30.

[0046] During the stripping stage, the traction motor 51 is temporarily stopped, the feeding plate 22 adsorbs the base film of the semi-finished product by negative pressure, and at the same time the lifting cylinder 23 drives the pressing block 24 to fall, pressing the semi-finished product tightly on the feeding plate 22 to ensure the stability of the stripping process. When everything is ready, the moving motor 34 and the traction motor 51 are started together. Specifically, the moving motor 34 rotates to drive the moving plate 31 to move towards the feeding plate 22 through the matching engagement of the gear 35 and the rack 36, forming a retraction effect. At the same time, the traction motor 51 pulls the base film. Due to the difference in material properties between the patches and the base film, the patches are separated from the base film at the cutting edge of the stripping knife 33.

[0047] After a piece of material is peeled off, the lifting cylinder 23 drives the pressing block 24 to rise away from the semi-finished product, preparing for the next peeling operation. The moving motor 34 reverses rotation to drive the moving plate 31 to move towards the material taking plate 41, conveying the peeled material to the material taking plate 41 for taking, while the bottom film is continuously pulled by the traction motor 51 and finally wound on the bottom film winding assembly 60. The above operation is repeated to continuously and stably peel the material and orderly convey the peeled material to the material taking plate 41 for taking.

[0048] During the whole process, the moving plate 31 is circularly moved under the matching engagement of the gear 35 and the rack 36, and the automatic peeling and supply of the material are realized through the peeling plate 32. Compared with the conventional material winding supply, the utility model utilizes the circular movement of the peeling plate 32 to facilitate the peeling of the material, omits the complex transmission mechanism, effectively reduces the overall manufacturing cost, and reduces the risk of failure.

[0049] In the embodiment, the bottom film winding assembly 60 and the cover film winding assembly 70 are common winding structures in the industry, and thus are not described in detail.

[0050] The rearward retraction type material winding supply has simple structure and is convenient to use. The matching engagement of the rack 36 and the gear 35 enables the moving motor 34 to drive the moving plate 31 to slide on the bearing plate 10 back and forth, thereby driving the circular movement of the peeling plate 32, realizing the automatic peeling and supply of the material, omitting the complex transmission mechanism, effectively reducing the overall manufacturing cost, and reducing the risk of failure.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.
