Description

Technical Field

[0001] This utility model relates to the technical field of printing material feeding, specifically a material feeding device for a printing press. Background Technology

[0002] During printing, a feeding device is needed to transport the fabric. Existing feeding devices use a vertical cleaning roller inside the feeding box to contact the fabric surface and drive the cleaning roller to clean the fabric. However, during the fabric transport process, it is impossible to guarantee the contact effect between the cleaning roller and the fabric at all times. Moreover, after prolonged use, dust will accumulate on the surface of the cleaning roller, which will affect the subsequent cleaning effect on the fabric. Therefore, those skilled in the art have proposed a feeding device for printing presses to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a feeding device for a printing press to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0015] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0016] Example 1: Please refer to Figure 1 , Figure 2 A feeding device for a printing press includes a feeding box 1. A transparent door 2 is provided at the front end of the feeding box 1. A first inlet slot 3 and a first outlet slot 4 are respectively provided at both ends of the feeding box 1. A first rotating shaft 7 and a second rotating shaft 8 are symmetrically arranged at the center of the inner cavity of the feeding box 1. Rotating rollers 9 are provided on both the first rotating shaft 7 and the second rotating shaft 8. Cleaning cylinders 10 are elastically connected to the periphery of the rotating rollers 9. The periphery of the two cleaning cylinders 10 respectively contacts both sides of the fabric 5 fed into the feeding box 1. The fabric 5 is partially bent after passing through the cleaning cylinders 10. A first cleaning box 11 is installed on the side of the cleaning cylinder 10 away from the fabric 5, and a second cleaning box 24 is provided on the side of the cleaning cylinder 10 closer to the fabric 5. The fabric 5 is conveyed between the cleaning cylinder 10 and the second cleaning box 24. A drive assembly is provided inside the feeding box 1. The drive assembly is used to drive the rotating roller 9 to rotate. Two traction rollers 17 are arranged vertically on the inner wall of the feeding box 1 and at the corresponding positions of the first inlet groove 3 and the first outlet groove 4 via a frame plate 16. A rotating component 18 is installed on the outer wall of one of the frame plates 16 to drive one of the traction rollers 17 to rotate.

[0017] Please see Figure 1 The drive assembly includes a first drive component 12, a first transmission belt 14, and a second transmission belt 15 installed in the feeding box 1. An output roller 13 is installed at the output end of the first drive component 12. The two ends of the first transmission belt 14 are respectively connected to the output roller 13 and the second rotating shaft 8. The two ends of the second transmission belt 15 are respectively connected to the first rotating shaft 7 and the second rotating shaft 8. The first rotating shaft 7 and the second rotating shaft 8 are each equipped with a structure that cooperates with the transmission belt, thereby facilitating the transmission belt to drive the corresponding rotating shaft to rotate.

[0018] Please see Figure 1, Figure 3 The outer wall of the rotating roller 9 is connected to the inner wall of the cleaning cylinder 10 through a number of circumferentially evenly distributed elastic elements 25. The surface of the cleaning cylinder 10 has bristles. When the cleaning cylinder 10 and the bristles squeeze the fabric 5 together, the corresponding elastic elements 25 are in a compressed state, thereby ensuring the contact effect between the cleaning cylinder 10 and the fabric 5.

[0019] Example 2: See Figure 1 , Figure 3 Based on Embodiment 1, a second driving member 21 is installed on the outer wall of the first cleaning box 11, a third rotating shaft 22 is installed inside the first cleaning box 11, and a cleaning roller 23 is installed on the third rotating shaft 22. Both the first cleaning box 11 and the second cleaning box 24 have slots 26 on the side near the cleaning cylinder 10. The two ends of the second cleaning box 24 are respectively provided with a second inlet slot 27 and a second outlet slot 28. A portion of the outer periphery of the cleaning cylinder 10 is placed inside the first cleaning box 11 through the slots 26 and contacts a portion of the outer periphery of the cleaning roller 23. The output end of the second driving member 21 is connected to the... One end of the third rotating shaft 22 is connected. The dust collection assembly 30 includes a fixed pipe 19, a dust collection bag 20, and a fan 29. The fixed pipe 19 is installed on the top of the feeding box. There is more than one fixed pipe 19. The bottom of the fixed pipe 19 is connected to the first cleaning box 11 and the second cleaning box 24 through a branch pipe. The fixed pipe 19 is also used to connect and fix the first cleaning box 11 and the second cleaning box 24. The dust collection bag 20 and the fan 29 are installed on the outer wall of one side of the feeding box 1 through a mounting frame structure. The two ends of the dust collection bag 20 are connected to the fixed pipe 19 and the fan 29, respectively.

[0020] Working principle: In use, the fabric 5 enters and exits the feeding box 1 through the first inlet groove 3 and the first outlet groove 4. The rotating component 18 drives the traction roller 17 to rotate, causing the fabric 5 to pass between the two cleaning cylinders 10. The outer peripheries of the two cleaning cylinders 10 contact the two sides of the fabric 5 respectively. The fabric 5 enters and exits the second cleaning box 24 through the second inlet groove 27 and the second outlet groove 28. The first driving component 12 drives the first transmission belt 14 to rotate, which in turn drives the second rotating shaft 8 to rotate. The second rotating shaft 8 drives the second transmission belt 15 to rotate, and the second transmission belt 15 drives the first rotating shaft 7 to rotate, which in turn drives the two cleaning cylinders 10 to rotate. The rotating roller 9 rotates, which in turn drives the cleaning cylinder 10 to rotate and clean the surface of the fabric 5. The dust cleaned off the fabric 5 is placed in the second cleaning box 24. The second driving component 21 drives the third rotating shaft 22 to rotate, which in turn drives the cleaning roller 23 to rotate and clean the dust on the cleaning cylinder 10. The dust cleaned off the cleaning cylinder 10 is placed in the first cleaning box 11. By starting the fan 29 and working with the fixed pipe 19 to suck in air, the air in the first cleaning box 11 and the second cleaning box 24 is sucked into the dust collector bag 20, and the dust is adsorbed and collected by the dust collector bag 20.
