DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 as shown, the present utility model provides the following technical solutions:

[0026] A paper feeding device for the production of positioning paper, comprising a driving member 3 and two symmetrically arranged feeding members 2. A feeding cavity for placing the raw material roll is formed on each of the two feeding members 2. The driving member 3 is located on one side of the feeding member 2. A tensioning member 4 for tensioning the positioning paper is installed on the driving member 3. The driving member 3 includes two base plates 31. A lead screw 32 is rotatably connected between the two base plates 31. The tensioning member 4 is sleeved on the lead screw 32. By rotating the lead screw 32, the tensioning member 4 reciprocates along the lead screw 32.

[0027] Through the above technical solution, when personnel need to feed the paper, place the raw material roll wound with the paper in the feeding cavity on the feeding member 2. After the raw material roll is placed, pull the paper on the raw material roll to unfold the paper, then pull the paper again to make the paper pass through the tensioning member 4, and then connect the paper passing through the tensioning member 4 to the positioning paper production equipment. By the operation of the production equipment, the paper is pulled, enabling the production equipment to carry out production. When the paper on the current raw material roll is used up, rotate the lead screw 32, so that the tensioning member 4 moves along the lead screw 32, making the tensioning member 4 move to the side of the other feeding member 2. Then connect the paper on the raw material roll of the current feeding member 2 to the production equipment according to the above steps, allowing the production equipment to continue producing positioning paper. And when the production equipment is producing positioning paper, personnel can remove the raw material roll on the previous feeding member 2 for replacement, enabling the device to operate continuously.

[0028] Regarding how the lead screw 32 rotates, as Figures 1-3 shown, a first motor 34 is fixedly connected to one of the base plates 31, and the output end of the first motor 34 is connected to the lead screw 32.

[0029] In this embodiment, by the operation of the first motor 34, the first motor 34 drives the lead screw 32 to rotate, and then the tensioning member 4 moves.

[0030] In order to make the tensioning member 4 move more smoothly, as Figures 1-4 shown, two guide rods 33 are symmetrically and fixedly connected between the two base plates 31. The lead screw 32 is located between the two guide rods 33. The tensioning member 4 is sleeved between the lead screw 32 and the two guide rods 33.

[0031] In this embodiment, when the lead screw 32 rotates, through the cooperation of the guide rods 33, the tensioning member 4 moves between the lead screw 32 and the guide rods 33, making the tensioning member 4 move more smoothly.

[0032] Specifically, in one embodiment, regarding the above feeding member 2:

[0033] As Figures 1-3 、 Figure 6As shown, the feeding member 2 includes two top plates 25. The tops of the two top plates 25 are both open to form placing grooves 26. A feeding cavity is formed between the two placing grooves 26. And both sides of the top plate 25 adjacent to the placing groove 26 are open to form inserting slots 27. Both inserting slots 27 communicate with the placing groove 26. And a movable limiting rod 22 is arranged between the two inserting slots 27 and the placing groove 26. One end of the limiting rod 22 is in screwed connection with a detachable connecting ring 23.

[0034] In this embodiment, when it is necessary to place the raw material roll, place the raw material roll between the placing grooves 26 between the two top plates 25. Then pass the limiting rod 22 through between the two inserting slots 27 on the top plate 25, and screw the connecting ring 23 with the limiting rod 22, so as to complete the installation of the raw material roll. When it is necessary to replace the raw material roll, unscrew the connecting ring 23 and pull out the limiting rod 22, then the raw material roll can be replaced.

[0035] In order to facilitate the adjustment of the position of the top plate 25, as Figures 1-4 and Figure 6 shown, it further includes a support member 1 for supporting the top plate 25. The support member 1 includes a support plate 11. Two top grooves 12 are symmetrically arranged at the open top of the support plate 11. The bottom of the substrate 31 is fixedly connected to the top of the support plate 11. A guide plate 21 is fixedly connected inside the top groove 12. The two top plates 25 are slidably connected to the guide plate 21.

[0036] In this embodiment, before the operator installs the raw material roll, pull the top plate 25 inside the top groove 12 to make the top plate 25 move along the guide plate 21, so as to adjust the distance between the two top plates 25, enabling the device to be adjusted according to the length of the raw material roll, thereby improving the usage range of the device.

[0037] When the operator adjusts the top plate 25, in order to make the position of the top plate 25 more stable after adjustment, as Figures 1-4 and Figure 6 shown, two side grooves 13 are symmetrically opened on one side of the support plate 11. The two side grooves 13 communicate with the two top grooves 12 respectively. A positioning screw 24 is arranged on one side of the support plate 11. The free end of the positioning screw 24 passes through the side groove 13 and is in screwed connection with the top plate 25.

[0038] In this embodiment, after the position of the top plate 25 is adjusted, pass the positioning screw 24 through the side groove 13 and screw it with the top plate 25, so as to fix the top plate 25, making the distance between the two top plates 25 easy to adjust according to the needs of the operator and improving the usage range of the device.

[0039] Specifically, in one embodiment, regarding the tensioning member 4:

[0040] As Figure 1 、 Figure 2 、 Figures 4-5As shown, the tensioning member 4 includes a bottom plate 41. The bottom plate 41 is sleeved between the lead screw 32 and the two guide rods 33. And symmetrically and fixedly connected to the top of the bottom plate 41 are two brackets 42. Between the two brackets 42 are provided two driving parts for driving the paper to move.

[0041] In this embodiment, when the position of the tensioning member 4 needs to be adjusted, by rotating the lead screw 32 and cooperating with the guide rods 33, the bottom plate 41 is moved, so that the bottom plate 41 drives the driving part to move to the position required by the operator. Then the paper is passed through the driving part, and the driving part drives the paper to move and tensions the paper.

[0042] In addition, in this utility model, regarding the above-mentioned driving part:

[0043] As Figures 1-2 、 Figures 4-5 shown, the driving part includes two mounting plates 44. Through holes are formed in the two brackets 42. Symmetrically rotatably connected between the two mounting plates 44 are two tensioning rollers 45. And on one side of the two mounting plates 44 facing the brackets 42 are fixedly connected insertion rods 46. The free ends of the insertion rods 46 slidably penetrate through the through holes, and detachably screwed on the insertion rods 46 are screw rings 47.

[0044] In this embodiment, the bottom plate 41 supports the brackets 42, the brackets 42 support the mounting plates 44, and the mounting plates 44 support the two tensioning rollers 45. By pulling the two mounting plates 44, the position of the mounting plates 44 is adjusted, and then the distance between the tensioning rollers 45 is adjusted. After the adjustment is completed, the screw rings 47 are screwed onto the insertion rods 46 to fix the position of the mounting plates 44. Then the paper is passed through the tensioning rollers 45, and the tensioning rollers 45 rotate to drive the paper to move.

[0045] Regarding how the tensioning rollers 45 rotate, as Figures 1-2 、 Figures 4-5 shown, fixedly connected to the mounting plates 44 are second motors 48. The output ends of the second motors 48 are connected to the tensioning rollers 45.

[0046] In order to make the placement groove 26 fit the raw material roller better, as Figure 6 shown, an arc-shaped groove is formed at the inner bottom end of the placement groove 26.

[0047] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
