Description

Technical Field

[0001] This utility model relates to the field of paper pressing mechanism technology, specifically a paper pressing mechanism for the production of paper packaging bags that is easy to adjust. Background Technology

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during production and distribution. Paper packaging bags are made by cutting, turning, gluing and cutting paper. In the production of paper packaging bags, paper is transported by conveying equipment. During the paper transport, a paper pressing mechanism is generally required to press the paper to ensure that the paper does not curl up during transport.

[0003] Existing paper pressing mechanisms generally use an adjusting screw and a bracket. Rotating the adjusting screw directly presses the pressure roller at the bottom of the adjusting screw onto the surface of the paper. This structure lacks cushioning, making pressure adjustment difficult. Slightly incorrect pressure can easily leave marks or even damage the paper. Furthermore, when using paper of different thicknesses, precise adjustments are required again, greatly reducing convenience. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a paper pressing mechanism for producing paper packaging bags that is easy to adjust. The pressure of the spring can be adjusted by turning the locking knob. The pressure of the spring causes the pressure roller to press against the paper. Compared with the traditional method of directly adjusting the pressure by the screw, this method has a certain degree of buffering and is less likely to press the paper ring or leave marks, thus ensuring the quality of the paper. At the same time, the spring pressure can be adjusted by turning the locking knob, which is simple to operate, can be quickly adjusted, and is applicable to paper of different thicknesses and materials, thereby solving the problems mentioned in the background art.

[0022] The fixing assembly includes a connecting sleeve 1, a support plate 2, and a screw knob 3. An extension sleeve 4 is coaxially provided on one side of the connecting sleeve 1. A limiting ring 5 is provided at the end of the extension sleeve 4 away from the connecting sleeve 1 and is fastened with bolts. The support plate 2 is connected to the outer surface of the connecting sleeve 1. Screw holes are provided at the connection between the support plate 2 and the connecting sleeve 1. The screw knob 3 is engaged with the screw holes of the support plate 2 and the connecting sleeve 1. A bent section 6 is provided at the end of the support plate 2 away from the connecting sleeve 1. A through hole is provided in the bent section 6.

[0023] The adjusting assembly includes a pressure plate 7, a positioning ring 8, a support screw 9, a spring 10, and a locking knob 11. An extension sleeve 4 is inserted into one end of the pressure plate 7. The pressure plate 7 is movably positioned between the connecting sleeve 1 and the limiting ring 5. A copper sleeve 14 is provided on the pressure plate 7. The extension sleeve 4 passes through the copper sleeve 14 and rotates with it. The copper sleeve 14 reduces the friction between the extension sleeve 4 and the pressure plate 7, thus ensuring smooth rotation between them. A pressure roller 12 is mounted on the side of the pressure plate 7 away from the extension sleeve 4 and the connecting sleeve 1 via an axle. A positioning ring 8 is rotatably mounted on the side of the pressure plate 7 near the pressure roller 12 and the connecting sleeve 1. A rotating shaft 15 is provided at one end of the positioning ring 8. The rotating shaft 15 passes through the pressure plate 7 and is equipped with a limiting pin, thus achieving a rotatable connection between the positioning ring 8 and the pressure plate 7. When the locking knob 11 is tightened, the positioning ring 8 rotates with the change of the angle of the support screw 9. The pressure plate 7 has a groove 16 on the side near the pressure roller 12 and located at the positioning ring 8 to ensure that the rotating shaft 15 and the limiting pin are located in the groove 16, so as to avoid affecting the installation of the pressure roller 12. The support screw 9 passes through the through hole of the bent section 6 and the positioning ring 8. The bottom of the support screw 9 and below the positioning ring 8 is provided with a first limiting nut 13. The support screw 9 is sleeved with a spring 10. The two ends of the spring 10 abut against the bent section 6 and the positioning ring 8 respectively. The locking knob 11 is threadedly connected to the support screw 9. The locking knob 11 is pressed against the upper surface of the bent section 6. The top of the support screw 9 is provided with a second limiting nut 17 to limit the locking knob 3 and prevent the locking knob 3 from being directly removed from the top of the support screw 9 due to operation error.

[0024] Assembly method and operating principle: First, weld one end of the support plate 2 to the connecting sleeve 1. Connect the pressure roller 12 to the pressure plate 7 via the wheel axle. Then, pass the rotating shaft 15 of the positioning ring 8 through the pressure plate 7 and pass the limiting pin through the rotating shaft 15 away from the positioning ring 8. Next, pass the extension sleeve 4 of the connecting sleeve 1 through the copper sleeve 14 of the pressure plate 7. Then, put the limiting ring 5 on the extension sleeve 4 away from the connecting sleeve 1 and tighten it with bolts. At this time, the pressure plate 7 is located between the limiting ring 5 and the connecting sleeve 1 and can rotate. Pass the support screw 9 through the bent section 6 of the support plate 2, and at the same time, put the spring 10 on the lower part of the support screw 9. Then, pass the bottom of the support screw 9 through the positioning ring 8 and screw on the first limiting nut 13. The bottom of the support screw 9 is limited by the first limiting nut 13. Then, screw the locking knob 11 on the upper part of the support screw 9 and press it against the upper surface of the bent section 6. Finally, screw the second limiting nut 17 on the top of the support screw 9 to complete the assembly. In use, the connecting sleeve 1 is connected to the crossbar of the conveying equipment. After adjusting the pressing mechanism to the corresponding position, the knob of the support screw 9 is turned to secure the connecting sleeve 1 to the crossbar of the conveying equipment. Then, the locking knob 11 is turned, and the pressure of the spring 10 causes the pressure plate 7 to press down, thereby pressing the pressure roller 12 onto the paper. This utility model has a reasonable structure. The pressure of the spring 10 can be adjusted by turning the locking knob 11, and the pressure of the spring 10 causes the pressure roller 12 to press onto the paper. Compared with the traditional method of directly adjusting the pressure through the support screw 9, it has a certain buffering effect and is less likely to press the paper ring or leave marks, thus ensuring paper quality. At the same time, the operation is simple and quick, and it is suitable for paper of different thicknesses and materials. Moreover, the overall structure is simple and easy to assemble and disassemble.
