[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1

[0031] A label positioning and cutting device, such as Figures 1 to 6As shown, the system includes a base 1. The top of the base 1 is equipped with an unwinding section for unwinding the label paper 10, a positioning and cutting section, and a conveying section. The positioning and cutting section includes a bracket 3 and a support frame 6. The support frame 6 is bolted to the outer top wall of the base 1. Supporting parts are rotatably connected to both sides of the support frame 6. The bracket 3 is welded to the outer top wall of the support frame 6. An electric telescopic rod 4 is bolted to the outer top wall of the bracket 3. A lifting plate 27 is pinned to the output end of the electric telescopic rod 4. A cutting tool is screwed to the bottom of the lifting plate 27. The blade 19 is provided, and an elastic element is installed on the lifting plate 27. A pressure plate 18 is fixed at the bottom of the elastic element. A clearance groove 17 for cooperating with the blade 19 is opened at the top of the support frame 6. A receiving frame 25 is welded to one side of the outer wall of the lifting plate 27. A rotating shaft 20 is rotatably connected to the through holes on both sides of the receiving frame 25. A torsion spring 26 is installed between the outer circumference of the rotating shaft 20 and the outer wall of one side of the receiving frame 25. A connecting frame 21 is fixed to the outer circumference of the rotating shaft 20. A smoothing roller 22 is rotatably connected to the inner walls on both sides of the connecting frame 21.

[0032] The label paper 10 is unwound by an unwinding section, and the conveying section, in conjunction with the unwinding section, conveys the label paper 10. The conveyed label paper 10 moves along the top of the support frame 6. After the label paper 10 has been conveyed to a set length, the lifting plate 27 is driven to move downward by the electric telescopic rod 4. Initially, the smoothing roller 22 is at its lowest point. After the support section rotates to be flush with the top of the support frame 6 and remains stable, the support section supports the conveying support frame 6. When the smoothing roller 22 moves to be in contact with the surface of the label paper 10, it continues to move downward with the lifting plate 27. The connecting frame 21 converts the vertical movement of the lifting plate 27 into the smoothing roller 22 moving along the label paper 10. During the lateral movement of the paper 10, the smoothing roller 22 rolls along the surface of the label paper 10, smoothing the label paper 10 and preventing it from curling during cutting, which would affect the accuracy of the cutting length. As the lifting plate 27 continues to move downward, the pressure plate 18 presses against the top of the smoothed label paper 10, positioning the label paper 10. When the pressure plate 18 moves to fit against the label paper 10, the elastic element undergoes elastic deformation as the lifting plate 27 continues to move downward, allowing the cutter 19 to continue moving downward. During the downward movement of the cutter 19, the label paper 10 is cut.

[0033] The elastic element includes a T-shaped rod 23 and a spring 24. The T-shaped rod 23 is slidably connected to the inner wall of the through hole on the surface of the lifting plate 27, and the bottom of the T-shaped rod 23 is fixedly connected to the pressure plate 18. The spring 24 is sleeved on the outer circumference of the T-shaped rod 23, and the two ends of the spring 24 are respectively snapped into the top outer wall of the lifting plate 27 and the top inner wall of the T-shaped rod 23.

[0034] The spring force of spring 24 allows the cutter 19 to continue moving down to cut the label paper 10 after the pressure plate 18 is pressed against the top of the support frame 6.

[0035] The support includes a placement plate 2 and a rotating rod 8. The rotating rod 8 is rotatably connected between the inner walls of both sides of the support frame 6, and the placement plate 2 is fixed to the outer circumference of the rotating rod 8. Both ends of the placement plate 2 are arc-shaped and maintain a gap with the support frame 6. A side plate 12 is welded to one side of the outer wall of the support frame 6, and an electric telescopic rod 13 is fixed to one side of the outer wall of the side plate 12 by bolts. A rack 15 is fixed to the output end of the electric telescopic rod 13 by a pin, and a gear 14 that meshes with the rack 15 is connected to the outer circumference of the rotating rod 8 by a key.

[0036] The electric telescopic rod 13 can drive the rack 15 to move laterally. During the movement, the rack 15 drives the gear 14 and the rotating rod 8 to rotate, which in turn drives the placement plate 2 to rotate. When the placement plate 2 rotates to be flush with the top of the support frame 6, the placement plate 2, together with the smoothing roller 22, smooths the label paper 10. After the label paper 10 is cut, the electric telescopic rod 13 drives the rack 15 to move again. During the movement, the rack 15 drives the gear 14 and the placement plate 2 to rotate. When the placement plate 2 is tilted, the cut label paper 10 slides down the surface of the placement plate 2, thereby preventing the cut label paper 10 from accumulating on the placement plate 2 and realizing the unloading of the cut label paper 10.

[0037] The unwinding section includes a rod 33 and a square plate 35. The square plate 35 is fixed to the top outer wall of the base 1 by bolts, and the rod 33 is rotatably connected to the inner wall of the through hole opened on the side of the square plate 35. The outer wall of the rod 33 is sleeved with a roll 34, and the label paper 10 is wound around the outer circumference of the roll 34.

[0038] The drum 34 can be installed by plugging in the provided plug rod 33.

[0039] The conveying unit includes a second rotating roller 32 and a support plate 36. The two support plates 36 are fixed to the top outer wall of the base 1 by bolts, and the second rotating roller 32 is rotatably connected between the two support plates 36. A drive motor 37 is fixed to one side outer wall of the support plate 36 by screws, and the output end of the drive motor 37 is connected to one end of the second rotating roller 32 by a coupling. The conveying unit also includes a mounting frame 9, a second spring 28 and a slide rod 29. The mounting frame 9 is fixed to the top outer wall of the base 1 by bolts, and the slide rod 29 is slidably connected to the inner wall of the through hole opened at the top of the mounting frame 9. The second spring 28 is fixed between the top inner wall of the slide rod 29 and the top outer wall of the mounting frame 9. A frame 11 is fixed to the bottom of the slide rod 29, and a first rotating roller 31 is rotatably connected to the inner walls on both sides of the frame 11.

[0040] The label paper 10 is tightly attached between the rotating roller 31 and the rotating roller 32 during the conveying process by the elastic force of the second spring 28. When the drive motor 37 drives the rotating roller 32 to rotate, the label paper 10 can be conveyed by the friction between the rotating roller 31 and the rotating roller 32.

[0041] A color mark sensor 30 is fixed to one outer wall of the frame 11 by bolts.

[0042] When the label paper 10 starts to be fed, the drive motor 37 starts and drives the rotating roller 32 to rotate, and the label paper 10 is fed. When the color mark sensor 30 detects the color mark on the label paper 10, the color mark sensor 30 will send a signal to the controller (not shown). The controller controls the color mark sensor 30 and the drive motor 37. After receiving the signal, the controller will calculate the distance that the label paper 10 has been fed and determine whether to stop feeding based on the preset length. If the label paper 10 has been fed for the set length, the controller will stop the drive motor 37 and stop the label paper 10 at the cutting position.

[0043] A collection frame 7 is placed on the top outer wall of the base 1;

[0044] The label paper 10 that slides down along the placement plate 2 can be collected by setting up a collection box 7.

[0045] The top outer wall of the base 1 is fixed with a vertical plate 5 by bolts, and a guide roller 16 is rotatably connected between the two vertical plates 5.

[0046] The guide roller 16 can guide the label paper 10.

[0047] Working principle: The label paper 10 is pre-wound onto the roll 34, which is installed on the square plate 35 via the insertion rod 33. When the device is started, the label paper 10 begins to unwind from the roll 34. After the drive motor 37 starts, it drives the rotating roller 32 to rotate via the coupling. The label paper 10 is conveyed under the friction between the rotating roller 31 and the rotating roller 32. At the same time, the elasticity of the spring 28 ensures that the label paper 10 is tightly attached to the rotating roller, ensuring the stability of the conveying. When the color mark sensor 30 detects the color mark on the label paper 10, it sends a signal to the controller. The controller determines whether to stop the drive motor 37 based on the preset length and the distance already conveyed, so that the label paper 10 stops at the predetermined cutting position. During the conveying process of the label paper 10, the smoothing roller 22 is installed on the lifting plate 27 via the connecting frame 21 and the rotating shaft 20. When the lifting plate 27 moves down, the smoothing roller 22 first... First, the label paper 10 is contacted. As the lifting plate 27 continues to move downward, the connecting frame 21 converts the vertical movement of the lifting plate 27 into the horizontal movement of the smoothing roller 22 along the label paper 10. The smoothing roller 22 smooths the label paper 10 during the rolling process, avoiding curling that affects the accuracy of the cutting length. When the lifting plate 27 continues to move downward, the pressure plate 18 first presses against the top of the smoothed label paper 10 to position it. At the same time, the elastic element begins to produce elastic deformation, allowing the cutter 19 to continue to move downward after the pressure plate 18 presses against it to cut the label paper 10. The cutter 19 completes the cutting action on the support frame 6 through the clearance groove 17. After the cutting is completed, the electric telescopic rod 13 drives the rack 15 to move laterally, and drives the placement plate 2 to rotate through the gear 14. When the placement plate 2 tilts, the cut label paper 10 slides down its surface into the collection frame 7. The collection frame 7 is used to collect the sliding label paper 10 for convenient subsequent sorting and use.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
