Description

Technical Field

[0001] This utility model relates to the field of printing guide roller assemblies, and more particularly to an antistatic guide roller assembly for printing. Background Technology

[0002] Existing antistatic guide rollers for printing are mostly made of conductive metal. They achieve antistatic effects by being connected to the equipment frame and then grounded through the frame. Static electricity on the printed matter can be conducted to the ground through the guide rollers. However, in the existing technology, the tension roller assembly for tensioning requires at least two guide rollers and one tension roller. Both ends of the three guide rollers are equipped with correction rings, and these rings are set independently. This makes the process of adjusting the position of the correction rings when the width of the paper being fed changes very cumbersome. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an antistatic guide roller assembly for printing, which solves the problem of cumbersome process of adjusting the position of the guide rollers due to the independent setting of multiple correction rings in existing guide roller assemblies.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] An antistatic guide roller assembly for printing includes a guide roller bracket. A steering guide roller is rotatably mounted on both the front and rear sides between two side plates of the guide roller bracket. A tension guide roller is vertically mounted in the middle between the two side plates. Two sets of correction components are symmetrically arranged on both sides of the two side plates along the printing conveying direction. Each correction component includes two first retaining rings respectively fitted onto the ends of the two steering guide rollers, a second retaining ring fitted onto the end of the tension guide roller, and a synchronization component connecting the two first retaining rings and the second retaining ring. The synchronization component enables the two first retaining rings and the second retaining ring to move synchronously as a whole. The distance between the two sets of correction components is adjusted by an adjustment component.

[0006] Optionally, a lifting sleeve is rotatably connected to both ends of the tensioning guide roller. The lifting sleeve surrounds the tensioning guide roller from the bottom. The two ends of the lifting sleeve are slidably nested in the through grooves in the middle of the two side plates. Baffles are symmetrically fixed at both ends of the lifting sleeve. The opposite side of the two baffles abuts against the outer wall of the opposite side of the two side plates, confining the lifting sleeve in the through groove. An electric push rod is fixed on the bottom plate of the guide roller bracket. The electric push rod is arranged longitudinally, and its extended end is fixed to the bottom surface of the lifting sleeve. The up and down position of the tensioning guide roller can be adjusted by the electric push rod, thereby achieving the effect of tension adjustment.

[0007] Optionally, the synchronization component includes a connecting strip fixed on two first retaining rings, the connecting strip passing over the tension guide roller, the length direction of the connecting strip being parallel to the printing conveying direction, and two longitudinally arranged slide rods symmetrically fixed on the outer wall of the second retaining ring, the upper end of the slide rods being slidably connected to the connecting strips through sliding holes, and an arc-shaped plate being fixed to the lower end of the slide rods, the arc-shaped plate being fixed to the outer wall of the second retaining ring, making the connection between the slide rods and the second retaining ring more stable.

[0008] Optionally, the adjustment assembly includes a bidirectional screw rotatably connected between two side plates via bearings. It is located in the middle of the guide roller bracket and passes over the two connecting strips. A threaded sleeve is fixed in the middle of the upper end of the connecting strips. The two threaded sleeves are threadedly connected to both ends of the bidirectional screw. The two ends of the bidirectional screw extend through the two side plates to both sides of the guide roller bracket and are fixed with knobs.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] 1. This utility model connects the first and second retaining rings by setting a synchronization component, so that the three retaining rings of the correction component can move synchronously as a whole. With the adjustment component, the distance between the two sets of correction components can be adjusted, which simplifies the adjustment process of the retaining ring position when the width of the conveyed paper changes and improves the ease of operation.

[0011] 2. This utility model uses an electric push rod to drive the lifting sleeve to raise and lower the tension guide roller. Combined with the sliding fit between the lifting sleeve and the through groove of the side plate and the limiting of the baffle, the tension guide roller can be raised and lowered stably, ensuring accurate tension adjustment, reducing the deviation of printed materials during transmission, and improving printing accuracy.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 5 This embodiment provides an antistatic guide roller assembly for printing, including a guide roller bracket 1. The main body of the guide roller bracket 1 is a side plate 101 arranged in parallel on both sides. The bottom of the two side plates 101 are connected by a base plate 102 to form a frame structure.

[0020] A guide roller 2 is rotatably mounted on both the front and rear sides between the two side plates 101 via bearings. The two guide rollers 2 are arranged in parallel and are used to support and transport printed materials (such as paper, film, etc.). Since the guide rollers 2 are made of conductive metal (such as stainless steel), their two ends are connected to the side plates 101 of the guide roller bracket 1. The side plates 101 are connected to the frame of the printing equipment, and the frame is grounded. This allows static electricity generated during the transport of printed materials to be conducted to the ground through the guide rollers 2, achieving an anti-static effect.

[0021] At the center of each of the two side plates 101, a longitudinal through groove 1011 is provided, penetrating the side plate 101. A lifting sleeve 3 is slidably nested within each of the two through grooves 1011. The lifting sleeve 3 surrounds the lower part of the tension guide roller 4 from below. The two ends of the tension guide roller 4 are rotatably connected to the inner wall of the lifting sleeve 3 via bearings, meaning that the tension guide roller 4 can rotate freely relative to the lifting sleeve 3. Two baffles 5 are symmetrically fixed at both ends of the lifting sleeve 3. The opposite sides of the two baffles 5 abut against the opposite outer walls of the two side plates 101, thereby confining the lifting sleeve 3 within the through groove 1011 and preventing it from falling out of the through groove 1011. A longitudinally arranged electric push rod 6 is fixed on the base plate 102 of the guide roller bracket 1. The extended end of the electric push rod 6 is fixedly connected to the bottom surface of the lifting sleeve 3. When the electric push rod 6 extends or retracts, it can drive the lifting sleeve 3 to slide up and down along the through groove 1011, thereby driving the tensioning guide roller 4 to rise and fall synchronously. By adjusting the relative height between the tensioning guide roller 4 and the two guide rollers 2, the tension of the printed matter is changed, achieving a stable tension adjustment effect and avoiding wrinkles or stretching deformation of the printed matter due to unstable tension.

[0022] Along the conveying direction of the printed matter, two sets of structures are symmetrically arranged on both sides between the two side plates 101 to prevent the printed matter from deviating. In each set of structures, a first retaining ring 7 is fitted at the end of each of the two guide rollers 2, and a second retaining ring 8 is fitted at the end of the tensioning guide roller 4. The first retaining ring 7 and the second retaining ring 8 can fit against the edge of the printed matter to play a limiting role.

[0023] A connecting strip 9 is fixed to the outer side of each of the two first retaining rings 7. The length of the connecting strip 9 is parallel to the printing conveying direction and passes over the tension guide roller 4. Two longitudinally arranged slide rods 10 are symmetrically fixed to the outer wall of the second retaining ring 8. The upper end of the slide rod 10 passes through the sliding hole on the connecting strip 9 and is slidably connected to the connecting strip 9. An arc plate 1001 is fixed to the lower end of the slide rod 10. The arc plate 1001 fits and is fixed to the outer wall of the second retaining ring 8, which enhances the stability of the connection between the slide rod 10 and the second retaining ring 8.

[0024] With the above structure, when the first retaining ring 7 moves, the second retaining ring 8 can be driven to move synchronously through the connecting bar 9 and the slide bar 10, ensuring that the three retaining rings always remain aligned and jointly limit the same edge of the printed material. When the height of the tensioning guide roller 4 is adjusted by the electric push rod 6, the second retaining ring 8 can slide up and down with the connecting bar 9. The presence of the connecting bar 9 will not hinder the second retaining ring 8 from moving up and down with the tensioning guide roller 4.

[0025] In the middle of the guide roller bracket 1, a bidirectional screw 11 is rotatably connected via a bearing. The bidirectional screw 11 passes over the connecting strips 9 in the two sets of structures, and its two ends extend through the side plates 101 to the outside of the guide roller bracket 1, where a knob 12 is fixed. A threaded sleeve 13 is fixed to the middle of the upper end of each connecting strip 9, and the two threaded sleeves 13 are threadedly connected to the two ends of the bidirectional screw 11. When the knob 12 is rotated, the bidirectional screw 11 rotates, which drives the two threaded sleeves 13 to move towards or away from each other along the bidirectional screw 11. This, in turn, drives the two sets of retaining rings to move closer or further apart synchronously via the connecting strips 9, achieving rapid adjustment of the distance between the two sets of retaining rings. When the width of the paper being conveyed changes, only the knob 12 needs to be rotated to complete the synchronous adjustment of the positions of all retaining rings, eliminating the need to adjust each retaining ring individually, greatly simplifying the operation process and improving adjustment efficiency.

[0026] In summary, this device, by integrating the synchronous movement structure of the retaining ring and the convenient spacing adjustment structure, effectively solves the problem of cumbersome adjustment caused by the independent setting of the traditional retaining ring while ensuring the anti-static and tension adjustment effects, thus improving the continuity and stability of printing production.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
