Description

Technical Field

[0001] This utility model relates to the field of antistatic guide roller technology, specifically to an antistatic guide roller for printing express waybills. Background Technology

[0002] In the production of express delivery waybills, static electricity can indeed cause problems such as dust attraction, misregistration, uneven paper delivery, and even ink ignition. Antistatic guide rollers are one of the key components for solving these problems, and their technology is constantly being developed and improved.

[0003] Traditional antistatic guide rollers only prevent charge accumulation or facilitate static discharge through surface coatings or material improvements. They cannot adequately protect the surface coating type antistatic agent. Prolonged contact with express delivery labels will cause its effectiveness to gradually decrease as the coating wears down, and it is not conducive to subsequent regular maintenance.

[0004] Therefore, it is necessary to invent an anti-static guide roller for printing express waybills to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an antistatic guide roller for printing express delivery waybills. By setting a detachable textured cover frame on the outer surface of the roller body, the contact area between the express delivery waybill and the antistatic agent coated on the outer surface of the roller body is reduced to a certain extent. This ensures that the conductivity is not interfered with while increasing the wear resistance of the overall structure, thereby improving the overall antistatic effect and service life. The installation block, limiting block, spring, pressing rod, locking block, and locking groove are arranged and used in combination to adjust the insertion state of the locking block and locking groove, as well as the stable connection between the textured cover frame and the bushing. This facilitates the subsequent disassembly and assembly of the protective device and enables regular maintenance. This addresses the problem in existing technologies where the surface coating of antistatic agent cannot provide sufficient protection, and prolonged contact with the express delivery waybill causes the coating's effectiveness to gradually decrease with wear, hindering subsequent regular maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an antistatic guide roller for printing express waybills, comprising a roller body, a roller shaft, and a mounting base. Both ends of the roller body are fixedly connected to the roller shaft. The surface of the roller body is coated with an antistatic agent. Bushings are symmetrically fitted on the roller shaft. A bracket is fixedly connected between each of the two bushings and the mounting base. A detachable protective device is symmetrically arranged on the roller body. The protective device includes a mesh-like cover frame and a mounting block. A movable groove is provided at the top and bottom of the bushing. A limit block is slidably arranged inside the movable groove. A spring is fixedly connected between the side of the limit block and the movable groove. A pressing rod penetrating the front side of the bushing is fixedly connected to the side of the limit block away from the spring. A movable groove matching the limit block is provided on the side of the mounting block close to the bushing. The end of the limit block extends into the movable groove and is fixedly connected to a locking block. A locking groove matching the locking block is provided on the inner side of the movable groove.

[0007] Preferably, the top of the mounting base is provided with a placement groove, a movable seat is movably disposed in the placement groove, a spring is fixedly connected between the placement groove and the movable seat, pressure edges are fixed on the front and rear sides of the movable seat, and cleaning bristles are fixedly disposed on the top of the movable seat.

[0008] Preferably, a limiting cavity is formed on both sides of the movable seat, and a limiting block two is slidably arranged inside the limiting cavity. A spring two is fixedly connected between one side of the limiting block two and the limiting cavity, and a locking block two is fixedly connected to the side of the limiting block two away from the spring two.

[0009] Preferably, push rods are movably inserted into both ends of the mounting base, and interactive grooves are formed inside the mounting base to cooperate with both the push rods and the locking block.

[0010] Preferably, the bottom of the interactive groove is provided with a guide groove, the bottom of the push rod is fixedly connected with a guide block that matches the guide groove, and a spring is fixedly connected between the side of the guide block and the guide groove.

[0011] Preferably, mounting ears are symmetrically fixed on both the front and rear sides of the mounting base.

[0012] Preferably, fastening holes are provided on both sides of the mounting base.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. By setting a detachable textured cover frame on the outer surface of the roller body, the contact area between the express delivery label and the antistatic agent coated on the outer surface of the roller body is reduced to a certain extent. This ensures that the conductivity is not affected while increasing the wear resistance of the overall structure, improving the overall antistatic effect and service life. The mounting block, limit block one, spring one, pressing rod, locking block one, and locking groove one, through their arrangement and coordination, allow for adjustment of the insertion state of locking block one and locking groove one, as well as the stable connection between the textured cover frame and the bushing. This facilitates subsequent disassembly and assembly of the protective device and enables regular maintenance.

[0015] 2. The cleaning brush bristles are designed to periodically remove dust adsorbed on the surface of the textured cover frame. The expansion of spring four keeps the top of the cleaning brush bristles in close contact with the surface of the textured cover frame, improving the cleaning effect and preventing the accumulation of impurities from affecting the anti-static effect. When the movable seat connected to the cleaning brush bristles is pressed into the mounting base by the pressing edge, the locking block two is pushed into the interactive groove by the elastically expanding spring two and locked, which can lock the state of separation between the cleaning brush bristles and the textured cover frame, facilitating the subsequent replacement of the protective device.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The antistatic guide roller for printing express waybills shown includes a roller body 1, a roller shaft 2 and a mounting base 13. Both ends of the roller body 1 are fixedly connected to the roller shaft 2. The surface of the roller body 1 is coated with an antistatic agent 101. The end of the roller shaft 2 has pre-set holes for easy connection with the express waybill printing device, which facilitates assembly.

[0026] The roller 2 is symmetrically fitted with bushings 3. Each bushing 3 is fixedly connected to the mounting base 13 with a bracket 12. The roller body 1 is symmetrically provided with detachable protective devices 4. The protective devices 4 include a mesh-like cover frame 401 and a mounting block 402. The detachable mesh-like cover frame 401 reduces the contact area between the express delivery label and the antistatic agent 101 coated on the outer surface of the roller body 1 to a certain extent, so that its conductivity is not interfered with and the wear resistance of the overall structure is increased. The mounting block 402 is used to securely connect with the bushing 3 for easy disassembly and assembly.

[0027] The top and bottom of the bushing 3 are provided with movable grooves 5. A limit block 6 is slidably arranged inside the movable groove 5. A spring 7 is fixedly connected between the side of the limit block 6 and the movable groove 5. A pressing rod 8 that passes through the front of the bushing 3 is fixedly connected to the side of the limit block 6 away from the spring 7. The side of the mounting block 402 close to the bushing 3 is provided with a movable groove 9 that matches the limit block 6. The end of the limit block 6 extends into the movable groove 9 and is fixedly connected with a locking block 10. The inner side of the movable groove 9 is provided with a locking groove 11 that matches the locking block 10. Pressing the pressing rod 8 can push the limit block 6 to slide in the movable groove 5 and the movable groove 9, so that the locking block 10 is separated from the locking groove 11, which makes it easy to remove the protective device 4.

[0028] The top of the mounting base 13 is provided with a mounting groove 14, and a movable seat 15 is movably arranged in the mounting groove 14. A spring 29 is fixedly connected between the mounting groove 14 and the movable seat 15. Pressure edges 16 are fixed on the front and rear sides of the movable seat 15. A cleaning brush 17 is fixedly arranged on the top of the movable seat 15. The expansion of the spring 29 keeps the cleaning brush 17 in close contact with the surface of the mesh cover frame 401. When the roller body 1 and the protective device 4 rotate, it is used to clean the surface dust to avoid affecting the anti-static effect.

[0029] Limiting cavities 18 are provided on both sides of the movable seat 15. Limiting blocks 19 are slidably arranged inside the limiting cavities 18. A spring 20 is fixedly connected between one side of the limiting block 19 and the limiting cavity 18. A locking block 21 is fixedly connected to the side of the limiting block 19 away from the spring 20. When the locking block 21 is engaged with the interactive groove 22, it is used to stabilize the movable seat 15 in the placement groove 14, so that there is a certain distance between the cleaning brush bristles 17 and the protective device 4, which allows the protective device 4 to be disassembled. The bottom of the locking block 21 is designed with a slope, so that when the pressing edge 16 is pressed, the movable seat 15 can be flexibly pushed into the placement groove 14, and the locking block 21 is bounced into the interactive groove 22 by the spring 20 for engagement.

[0030] Push rods 23 are movably inserted into both ends of the mounting base 13. An interactive groove 22 is opened inside the mounting base 13 to cooperate with both the push rods 23 and the second locking block 21. The push rods 23 can move in the interactive groove 22 to push the second locking block 21 into the limiting cavity 18, so that the brush bristles 17 can be pushed out by the fourth spring 29 and the mesh cover frame 401 and come into contact with the protective device 4.

[0031] The bottom of the interactive groove 22 is provided with a guide groove 24. The bottom of the push rod 23 is fixedly connected with a guide block 25 that matches the guide groove 24. A spring 3 26 is fixedly connected between the side of the guide block 25 and the guide groove 24. The guide block 25 slides along the guide groove 24 to assist the push rod 23 in stably pushing the second block 21.

[0032] Mounting ears 27 are symmetrically fixed on both the front and rear sides of the mounting base 13.

[0033] Fastening holes 28 are provided on both sides of the mounting base 13. The mounting ears 27 and the fastening holes 28 cooperate to fix the mounting base 13 to the printing device without hindering the use of the roller body 1.

[0034] The working principle of this practical application is as follows:

[0035] First, the mounting base 13 is fixed to the printing device through the mounting ear 27 and fastening hole 28. The roller body 1 is connected to the sheet output position in the printing device through the roller shaft 2. Press the pressing rod 8 and place the protective device 4 above and below the roller body 1 and the bushing 3 respectively. After alignment, release the force of pressing the pressing rod 8. The spring 7 will cause the locking block 10 to automatically engage with the locking groove 11, completing the installation of the protective device 4. During this process, press the push rod 23 inward. With the guidance of the guide block 25 sliding along the guide groove 24, the push rod 23 pushes the locking block 21 into the limiting cavity 18. The movable seat 15 will be pushed out by the elasticity of the spring 49. Then the cleaning brush bristles 17 will contact the surface of the mesh cover frame 401 to remove dust from the protective device 4 during the rotation process.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
