Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and more specifically, to a green and energy-saving printing device. Background Technology

[0002] Printing is a technology that involves transferring ink from original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials to the surface of materials like paper, textiles, plastics, leather, PVC, and PC through processes such as plate making, inking, and pressing. It involves transferring approved printing plates onto the substrate using printing machinery and specialized inks; currently, printing equipment is widely used to complete the printing process.

[0003] For example, the green and energy-saving printing device disclosed in authorization announcement number CN216004555U uses guide rollers, movable support components, springs and positioning rollers to position the printed matter, preventing the printed matter from shifting during the printing process and causing the printed product to be unqualified. The positioning rollers work with the conveying device to transport the printed matter, ensuring accurate positioning while preventing the printed matter from deforming due to excessive pulling.

[0004] In the above, although the printed materials are positioned by the support components, in actual use, the positioning rollers are used to fix and limit the printed materials. Due to long-term operation, the friction between the positioning rollers and their own bearings will increase, resulting in the positioning rollers not rolling smoothly. At the same time, it will also increase the friction between the positioning rollers and the printed materials, affecting the conveying of the printed materials. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a green and energy-saving printing device that can reduce the friction between the positioning rollers.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A green and energy-saving printing device includes a side plate and a support assembly connected to the side plate. The support assembly is connected to a positioning roller. The positioning roller includes a mounting base and a connecting rod placed on the inner wall of the mounting base. A wheel body is sleeved on the connecting rod and the wheel body is rotatably connected to the connecting rod.

[0008] The connecting rod has a cavity inside, and the outer peripheral wall of the connecting rod has several sliding grooves that communicate with the cavity at equal intervals. The mounting seat has a mounting groove that communicates with the cavity on its inner wall, and a rotating hole is provided on one side wall of the mounting seat relative to the mounting groove.

[0009] The mounting groove is equipped with a sliding block, a rotating rod, and a guide rod. The sliding block is sleeved on the outer peripheral wall of the rotating rod and the guide rod. The rotating rod is rotatably connected to the mounting groove, and the inner wall of the sliding block meshes with the rotating rod.

[0010] The upper surface of the mounting base has a feeding hole, which is connected to the rotating hole. The outer peripheral wall of the sliding block is provided with several bristles.

[0011] The present invention is further configured such that: a ball bearing is rolledly connected to the inner wall of the mounting groove, one end of the rotating rod abuts against the ball bearing, a locking block is provided in the mounting groove to prevent the ball bearing from falling off, and both ends of the guide rod are fixedly connected to the inner wall of the mounting groove and the inner wall of the rotating hole.

[0012] The present invention is further configured such that: one end of the rotating rod is placed outside the rotating hole, and a rotating handle is provided at the end of the rotating rod placed outside the rotating hole.

[0013] The present invention is further configured such that: the diameter of the sliding block is greater than or less than the width of the cavity, the diameter of the sliding block plus the diameter of the brush bristles is greater than the width of the cavity, and the brush bristles abut against the inner wall of the wheel.

[0014] The present invention is further configured such that the bristles are made of a soft material.

[0015] Compared with the shortcomings of the existing technology, the beneficial effects of this utility model are as follows:

[0016] By having the axial cavity and circumferential groove inside the positioning roller work together, the lubricant can be evenly penetrated into the rotating parts of the wheel along the cavity, thereby reducing the coefficient of friction between the wheel and the connecting rod. At the same time, the bristles on the outer peripheral wall of the sliding block form elastic contact with the inner wall of the wheel, which can adhere to and drive the lubricant while cleaning residual ink, so that the lubricant can be locally circulated inside the wheel, reducing the possibility of lubricant spillage and improving the stable conveying effect of the positioning roller.

Therefore, they should not be construed as limitations on this utility model.

[0022] Working principle: When the operator needs to maintain the positioning roller, first inject an appropriate amount of environmentally friendly lubricant through the feeding hole 12. The lubricant flows into the cavity 6 of the connecting rod 4 through the mounting groove 8, and then seeps evenly to the bearing surface of the wheel body 5 through the annularly distributed sliding groove 7. Then, hold the rotating handle 15 and rotate it clockwise two and a half turns, which drives the rotating rod 10 to drive the sliding block 9 to move forward three centimeters along the guide rod 11. At this time, the nylon bristles 14 form elastic contact with the inner wall of the wheel body 5, which can scrape off residual ink without causing scratches. At the same time, the lubricant falls onto the bristles 14, and the bristles 14 drive the lubricant to lubricate the inner wall of the connecting rod 4 and the wheel body 5, which can avoid lubricant leakage and pollution.

[0023] like Figures 1 to 2 As shown, this utility model includes a side plate 1 and a support assembly 2 connected to the side plate 1. The support assembly 2 is connected to a positioning roller. The positioning roller includes a mounting base 3 and a connecting rod 4 placed on the inner wall of the mounting base 3. A wheel body 5 is sleeved on the connecting rod 4. The wheel body 5 is rotatably connected to the connecting rod 4. The printed material is fixed and limited by the contact between the wheel body 5 and the printed material.

[0024] The connecting rod 4 has a cavity 6 inside, and the outer peripheral wall of the connecting rod 4 has several grooves 7 that communicate with the cavity 6 at equal intervals. The mounting base 3 has a mounting groove 8 that communicates with the cavity 6 on its inner wall. The mounting base 3 has a rotating hole on one side wall opposite to the mounting groove 8. The rotating rod 10 is controlled to rotate by extending one end of the rotating rod 10 out of the rotating hole.

[0025] The mounting groove 8 is provided with a sliding block 9, a rotating rod 10 and a guide rod 11. The sliding block 9 is sleeved on the outer peripheral wall of the rotating rod 10 and the guide rod 11. One end of the rotating rod 10 is placed outside the rotating hole. The end of the rotating rod 10 placed outside the rotating hole is provided with a rotating handle 15. The rotating rod 10 is rotated by holding the rotating handle 15.

[0026] The rotating rod 10 is rotatably connected to the mounting groove 8. The inner wall of the mounting groove 8 is connected with a ball bearing 13. One end of the rotating rod 10 abuts against the ball bearing 13. The mounting groove 8 is provided with a locking block to prevent the ball bearing 13 from falling off. The two ends of the guide rod 11 are fixedly connected to the inner wall of the mounting groove 8 and the inner wall of the rotating hole to ensure that the rotating rod 10 remains stable during rotation.

[0027] The inner wall of the sliding block 9 engages with the rotating rod 10, which facilitates the movement of the sliding block 9 when the rotating rod 10 rotates.

[0028] The upper surface of the mounting base 3 is provided with a feeding hole 12, which is connected to the rotating hole. The outer peripheral wall of the sliding block 9 is provided with several bristles 14.

[0029] The diameter of the sliding block 9 is greater than or less than the width of the cavity 6. The diameter of the sliding block 9 plus the diameter of the bristles 14 is greater than the width of the cavity 6. The bristles 14 abut against the inner wall of the wheel body 5. The bristles 14 are made of soft material. During the movement of the sliding block 9, the bristles 14 deform and form elastic contact with the inner wall of the wheel body 5, which facilitates the cleaning of residual ink and promotes the local diffusion and lubrication of lubricant inside the wheel body 5.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
