Description

Technical Field

[0001] This utility model relates to the field of banknote printing and processing technology, specifically to a precision transmission rubber roller for banknotes. Background Technology

[0002] Highly precise transmission devices are required in banknote printing and processing to ensure accurate alignment, transfer, and handling of banknotes. Precision transmission rollers are used to control and transfer banknotes, ensuring accuracy in printing, cutting, and processing. The performance of these precision transmission rollers directly affects the quality and efficiency of banknote production.

[0003] Currently, most precision transmission rollers on the market adopt a one-piece design. This design presents some problems when adapting to different frames and transmission systems. Typically, rollers of different lengths need to be customized to meet specific requirements, increasing costs and delivery time. Furthermore, the adjustment and maintenance of one-piece rollers are relatively difficult, especially when different lengths are required. Because the length of the one-piece roller is not adjustable, mismatches occur on different frames, leading to unstable banknote transfer and potential errors. In addition, due to the design limitations of the rollers, more maintenance and more frequent replacements may be needed, increasing production costs and downtime.

[0004] Therefore, there is an urgent need for a precision transmission rubber roller for banknotes to solve the technical defects mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a precision transmission roller for banknotes, in order to solve the problem of the integrated design and lack of adjustability mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision transmission rubber roller for banknotes, comprising a rubber sleeve and an inner roller shaft, wherein roller sleeves are movably sleeved on both sides of the inner roller shaft, and hollow cavities are respectively opened on the other end face of the roller sleeves, a hollow through-hole rubber sleeve is provided outside the inner roller shaft, and an adjusting sleeve is fixedly sleeved in the middle section of the roller sleeves, the roller sleeves penetrate through both sides of the rubber sleeves to the outside, and sliding grooves are opened inside the roller sleeves and the adjusting sleeves, and locking screws are fixedly connected to the two side edges of the rubber sleeves, and the adjusting sleeves, roller sleeves and inner roller shaft are fixed in position by locking screws.

[0007] Preferably, the outer wall of the adjusting sleeve is machined with scale markings, and four sets of sliding grooves are provided, respectively located around the outer wall of the adjusting sleeve.

[0008] Preferably, the inner roller shaft, roller sleeve, and adjusting sleeve form a concentric circle structure, with their diameters arranged from largest to smallest as follows: adjusting sleeve > roller sleeve > inner roller shaft.

[0009] Preferably, keyways are provided at the four corners of the inner wall of the hollow cavity, a drive roller is assembled in one set of hollow cavities, and mounting screws are fixedly connected between the hollow cavity and the drive roller. Four sets of mounting keys are machined on the outer wall of the drive roller. The mounting keys and keyways are fitted and matched, and the mounting keys form a "+" structure.

[0010] Preferably, the inner wall of the roller sleeve is machined with first teeth on the upper and lower surfaces, and the outer wall of the inner roller shaft is machined with multiple sets of second teeth on the upper and lower surfaces, wherein the first teeth and the second teeth are respectively engaged and locked together.

[0011] Preferably, the outer wall of the rubber sleeve is coated with a three-layer composite coating, the innermost layer being a silicone coating, the middle layer being a polytetrafluoroethylene coating, and the outermost layer being a diamond coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the precision transmission rubber roller for banknotes not only improves the stability and applicability of precision transmission, reduces maintenance costs, and extends the life of the rubber roller, but also reduces wear and friction, and improves transmission efficiency and accuracy;

[0013] (1) By setting up a rubber sleeve, inner roller shaft, roller sleeve, scale markings, first tooth, and second tooth, the rubber roller is mainly composed of two parts: an outer rubber sleeve and an inner inner roller shaft. It has an adjustable design. By pulling out two sets of roller sleeves, it can be easily extended or shortened to adapt to different types of frames and transmission systems. This adjustable length design not only facilitates the installation and adaptation of the rubber roller, but also provides operators with convenient scale markings to ensure that the lengths on the left and right sides are uniform. When adjusting the length, the inner roller shaft and roller sleeve increase frictional resistance through the meshing of the first tooth and the second tooth, making the connection more compact and preventing relative rotation, thereby improving the stability and applicability of precision transmission.

[0014] (2) By setting up a drive roller, mounting screws, mounting keys, and keyways, the rubber roller adopts a detachable design. The drive roller can be installed on either the left or right side of the hollow cavity. Since the drive roller is in direct contact with the external drive mechanism and is prone to wear, the drive roller can be removed and replaced by removing the mounting screws. When reinstalling the drive roller, the four sets of mounting keys and keyways are fitted in a corresponding manner to prevent relative rotation, which reduces maintenance costs, extends the life of the rubber roller, and ensures efficient operation.

[0015] (3) By setting a silicone coating, a polytetrafluoroethylene coating and a diamond coating, the rubber roller adopts a three-layer coating design, including a silicone coating, a polytetrafluoroethylene coating and a diamond coating. The diamond coating provides superior wear resistance, the polytetrafluoroethylene coating has excellent lubricity and anti-stick properties, and the silicone coating provides good adsorption properties, so that the rubber roller can run smoothly, reduce wear and friction, thereby improving transmission efficiency and accuracy.

Slide grooves 5 are opened inside the roller sleeve 3 and the rubber sleeve 1 is fixedly connected to the two edges of the rubber sleeve 1. The adjusting sleeve 4, roller sleeve 3 and inner roller shaft 2 are fixed in position by the locking screws 6. The outer wall of the adjusting sleeve 4 is machined with scale markings 7. Four sets of slide grooves 5 are provided, which are located around the outer wall of the adjusting sleeve 4.

It has an adjustable design, which can be easily extended or shortened by pulling out the two sets of roller sleeves 3 to adapt to different types of frames and transmission systems. This adjustable length design not only facilitates the installation and adaptation of the rubber roller, but also provides operators with convenient scale markings 7 to ensure that the length on the left and right sides is uniform. When adjusting the length, the inner roller shaft 2 and the roller sleeve 3 increase the frictional resistance through the meshing of the first tooth 11 and the second tooth 12.

[0024] Example 2: The inner roller shaft 2, roller sleeve 3 and adjusting sleeve 4 form a concentric circle structure. The diameters are arranged from largest to smallest as follows: adjusting sleeve 4 > roller sleeve 3 > inner roller shaft 2. Keyways 14 are respectively opened at the four corners of the inner wall of the hollow cavity 10. A drive roller 9 is assembled in a set of hollow cavities 10.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, the rubber roller adopts a detachable design, and the drive roller 9 can be installed on either the left or right side of the hollow cavity 10. Since the drive roller 9 is in direct contact with the external drive mechanism and is prone to wear, the drive roller 9 can be removed and replaced by removing the mounting screws 8. When reinstalling the drive roller 9, the four sets of mounting keys 13 and keyways 14 are engaged to prevent relative rotation.

[0026] Example 3: The outer wall of the rubber sleeve 1 is coated with a three-layer composite coating, the innermost layer is a silicone coating 17, the middle layer is a polytetrafluoroethylene coating 16, and the outermost layer is a diamond coating 15.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, the rubber roller adopts a three-layer coating design, including a silicone coating 17, a polytetrafluoroethylene coating 16, and a diamond coating 15. The diamond coating 15 provides superior wear resistance, the polytetrafluoroethylene coating 16 has excellent lubricity and anti-stick properties, and the silicone coating 17 provides good adsorption properties, enabling the rubber roller to operate smoothly.

[0028] Working principle: The rubber roller mainly consists of two parts: an outer rubber sleeve 1 and an inner roller shaft 2. It features an adjustable design; by pulling out the two sets of roller sleeves 3, it can be easily extended or shortened to adapt to different types of frames and transmission systems. Convenient scale markings 7 are provided for operators to ensure uniform length on both sides. When adjusting the length, the inner roller shaft 2 and roller sleeve 3 increase frictional resistance through the meshing of the first tooth 11 and the second tooth 12, preventing relative rotation. The rubber roller adopts a detachable design, allowing drive rollers 9 to be installed on either the left or right side of the hollow cavity 10. Since the drive roller 9 is in direct contact with the external drive mechanism and is prone to wear, the drive roller 9 can be removed and replaced by removing the mounting screws 8. When reinstalling the drive roller 9, the four sets of mounting keys 13 and keyways 14 are fitted together to prevent relative rotation. The rubber roller adopts a three-layer coating design, including a silicone coating 17, a polytetrafluoroethylene coating 16, and a diamond coating 15. The diamond coating 15 provides superior wear resistance, the polytetrafluoroethylene coating 16 has excellent lubricity and anti-stick properties, and the silicone coating 17 provides good adsorption properties, allowing the rubber roller to operate smoothly and reducing wear and friction.
