Technical Field

[0001] This utility model relates to the field of label processing technology, and in particular to a multi-layer pressing device for labels. Background Technology

[0002] Labels are identification objects attached to goods or their packaging. They are mainly used to indicate key information such as product name, place of origin, ingredients, uses and shelf life. They also have a certain decorative function. In the production process of labels, in order to facilitate storage, transportation and subsequent use, multiple labels are usually pressed together and neatly rolled into a roll.

[0003] During the winding process, some labels are suspended in the air, which can cause them to loosen. Loose labels cannot be kept flat during subsequent winding, resulting in wrinkles and affecting the quality of the finished product. Therefore, this application proposes a multi-layer pressing device for labels. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that label paper is prone to wrinkling during winding, and to propose a multi-layer pressing device for labels.

[0016] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 and Figure 2 As shown, this utility model proposes a multi-layer pressing device for labels, including a connecting frame 2 installed on the top of a processing table 1. The processing table 1 supports the connecting frame 2. The connecting frame 2 is connected to the processing table 1 by bolts. The outer side of the connecting frame 2 is rotatably connected to a first transmission roller 3, a pressure roller 4, a second transmission roller 5, a guide roller 6, and a take-up roller 7. The label paper is passed between the first transmission roller 3 and the pressure roller 4 and adhered to the outer side of the second transmission roller 5 and the guide roller 6, and finally connected to the take-up roller 7. When the first transmission roller 3 and the second transmission roller 5 rotate, the label paper is conveyed. As the take-up roller 7 rotates, the take-up roller 7 finally winds up the label paper. At this time, the label paper is wrapped and pressed together layer by layer, thereby realizing the function of multi-layer pressing. It should be noted that the first transmission roller 3, the second transmission roller 5, and the take-up roller 7 in this embodiment are all existing technologies and are mature. They will not be elaborated on in this embodiment.

[0020] As one implementation method, such as Figure 2 , Figure 3 and Figure 4As shown, the multi-layer pressing device also includes a connecting box 8, with a fixing plate 9 fixedly connected to the top of the connecting box 8. The fixing plate 9 is bolted to the outside of the connecting frame 2. This connection method facilitates the assembly and disassembly of the connecting box 8. A transmission box 10 is slidably connected inside the fixing plate 9, and a pressing wheel 11 is rotatably connected to the bottom of the transmission box 10. The connection surfaces of the transmission box 10 and the connecting box 8 are both made of rubber, which can ensure the sealing of the connection between the connecting box 8 and the transmission box 10. An air compressor mechanism, connected to the connecting box 8, is used to increase... The air pressure inside the large connecting box 8 causes the transmission box 10 to drive the pressure roller 11 downward to squeeze the label paper. When the air compressor is running, it inflates the inside of the connecting box 8. As the air pressure inside the connecting box 8 increases, the air pressure will push the transmission box 10 downward. The downward movement of the transmission box 10 will drive the pressure roller 11 to move downward synchronously. As the pressure roller 11 moves downward, it will eventually contact and squeeze the label paper, thereby tightening the loose label paper, thus improving the adhesion when the label paper is wound and avoiding the label paper wrinkles.

[0021] Furthermore, such as Figure 3 and Figure 4 As shown, the multi-layer pressing device in this embodiment also includes a reset mechanism, which is connected to the connecting box 8 and the transmission box 10. It is used to drive the transmission box 10 to move upward and reset. When the transmission box 10 moves downward, the transmission box 10 will drive the reset mechanism to deform. When the air compressor stops pressurizing the inside of the connecting box 8, the reset mechanism will drive the transmission box 10 to move upward. The upward movement of the transmission box 10 will drive the pressing wheel 11 to move upward synchronously. The upward movement of the pressing wheel 11 will release the pressure on the label paper, making it easier for the operator to pick up the label paper.

[0022] As one implementation method, such as Figure 2 and Figure 3 As shown, the air compressor mechanism includes an air pump 12 and a transmission pipe 13. The air compressor mechanism is described in detail below: The air pump 12 is installed at the top of the processing table 1. The transmission pipe 13 is connected to the output end of the air pump 12. When the air pump 12 is running, it will inflate the inside of the transmission pipe 13 from the output end. The end of the transmission pipe 13 away from the air pump 12 is fixedly connected to the inside of the connecting box 8. The transmission pipe 13 transmits the air from the air pump 12 to the inside of the connecting box 8, thereby increasing the internal air pressure of the connecting box 8. It should be noted that the air pump 12 is a mature existing technology. When the pressure roller 11 squeezes the label paper to a specified strength, the specified strength depends on the actual situation. The gas transmitted by the air pump 12 can be in a constant state, that is, the pressure roller 11 is in a state of continuously squeezing the label paper, but does not continue to move downward.

[0023] Furthermore, such as Figure 3 and Figure 4 As shown, the reset mechanism includes a connecting plate 14, a connecting plate 15, and a spring 16. The reset mechanism is described in detail below: The first connecting plate 14 is fixed to both sides of the connecting box 8, and the second connecting plate 15 is fixed to both sides of the transmission box 10. When the transmission box 10 moves down, it will drive the second connecting plate 15 to move down synchronously. The first spring 16 is fixed between the first connecting plate 14 and the second connecting plate 15. When the second connecting plate 15 moves down, it will cooperate with the fixed connecting plate 14 to pull the first spring 16. The first spring 16 will deform under force and generate elastic potential energy. When the air pump 12 stops, that is, when the internal pressure of the connecting box 8 stops, the first spring 16 will release the elastic potential energy and pull the second connecting plate 15 to move up. The second connecting plate 15 moving up will drive the transmission box 10 to move up. The movement of the transmission box 10 will eventually drive the pressure roller 11 to move up and release the pressure on the label paper.

[0024] Furthermore, such as Figure 4 As shown, an air outlet pipe 17 is fixedly connected inside the transmission box 10. When gas enters the interior of the connecting box 8, some air will also be discharged through the air outlet pipe 17. The air outlet pipe 17 is designed in an L shape, with the end of the air outlet pipe 17 away from the transmission box 10 facing the label paper. The discharged air will blow towards the label paper. The resulting wind force can not only work with the pressure roller 11 to squeeze and tighten the label paper, but also blow away impurities on the surface of the label paper, making it easier to rewind later.

[0025] Among them, such as Figure 4 and Figure 5 As shown, a concave plate 19 is fixedly connected to the outside of the transmission box 10. The concave plate 19 is connected to the transmission box 10 by bolts. A baffle 20 is slidably connected inside the concave plate 19. In the initial state, the baffle 20 is located inside the concave plate 19. When the equipment is stopped and the air outlet pipe 17 is not needed, the baffle 20 can be pulled out from inside the concave plate 19 so that the baffle 20 blocks the air outlet of the air outlet pipe 17. At this time, dust can be effectively prevented from entering the interior of the air outlet pipe 17.

[0026] As one implementation method, such as Figure 5 As shown, a rubber plate 21 is glued to the top of the baffle 20. The rubber plate 21 and the baffle 20 are the same size, which can increase the contact area between the rubber plate 21 and the baffle 20. A rubber ring 18 is glued to the bottom of the vent pipe 17. When the baffle 20 is located below the vent pipe 17, the rubber plate 21 and the rubber ring 18 are attached together. Since both the rubber plate 21 and the rubber ring 18 are made of rubber, the sealing performance can be improved.

[0027] Furthermore, such as Figure 4As shown, a limiting rod 22 is fixedly connected to the top of the second connecting plate 15. When the second connecting plate 15 moves, it will simultaneously drive the limiting rod 22 to move downward. The top of the limiting rod 22 is in contact with the bottom of the first connecting plate 14. When the second connecting plate 15 moves downward, it will drive the limiting rod 22 to disengage from the first connecting plate 14. When the second connecting plate 15 moves upward and resets, the limiting rod 22 will contact the first connecting plate 14, thereby preventing the second connecting plate 15 from moving upward too much and causing the air outlet pipe 17 to collide with the connecting box 8, thus avoiding damage to the air outlet pipe 17.

[0028] In addition, such as Figure 4 As shown, there are three sets of air outlet pipes 17 arranged in a linear array on the outside of the transmission box 10. The arrangement of the three sets of air outlet pipes 17 can increase the air force and improve the surface cleaning effect of the label paper. It should be noted that the common internal diameter of the three sets of air outlet pipes 17 is smaller than the internal diameter of the transmission pipe 13. Therefore, the amount of air transmitted by the transmission pipe 13 is greater than the sum of the amount of air transmitted by the three sets of air outlet pipes 17.

[0029] In this embodiment, the label paper is passed between the first transport roller 3 and the pressure roller 4, and adhered to the outside of the second transport roller 5 and the guide roller 6, and finally connected to the take-up roller 7. When the first transport roller 3 and the second transport roller 5 rotate, the label paper is conveyed. As the take-up roller 7 rotates, it finally winds up the label paper. At this time, the label paper is wrapped and pressed together layer by layer, thereby achieving the function of multi-layer pressing. During the pressing and winding of the label paper, the air pump 12 is started. When the air pump 12 is running, it will inflate the inside of the transport pipe 13 from the output end. The transport pipe 13 transmits the air from the air pump 12 to the inside of the connecting box 8, thereby increasing the internal air pressure of the connecting box 8. As the internal air pressure of the connecting box 8 increases, the air pressure will push the transmission box 1. As the transmission box 10 moves downward, the pressure roller 11 moves downward synchronously. As the pressure roller 11 moves downward, it eventually contacts and squeezes the label paper, thus tightening the loose label paper. When the transmission box 10 moves downward, it also drives the connecting plate 2 15 to move downward synchronously. The downward movement of the connecting plate 2 15, in conjunction with the fixed connecting plate 1 14, pulls the spring 16. The spring 16 deforms under force and generates elastic potential energy. When the air pump 12 stops, that is, when the internal pressure of the connecting box 8 stops, the spring 16 releases its elastic potential energy, pulling the connecting plate 2 15 upward. The upward movement of the connecting plate 2 15 drives the transmission box 10 upward, which in turn drives the pressure roller 11 upward to release the pressure on the label paper. When gas enters the interior of the connecting box 8, some air will also be discharged through the air outlet pipe 17. The end of the air outlet pipe 17 away from the transmission box 10 is facing the label paper. The discharged air will blow towards the label paper. The resulting wind force can not only work with the pressure roller 11 to squeeze and tighten the label paper, but also blow away impurities on the surface of the label paper. In the initial state, the baffle 20 is located inside the concave plate 19. When the equipment is stopped and the air outlet pipe 17 is not needed, the baffle 20 can be pulled out from inside the concave plate 19 so that the baffle 20 blocks the air outlet of the air outlet pipe 17. At this time, dust can be effectively prevented from entering the interior of the air outlet pipe 17.
