Description

Technical Field

[0001] The utility model relates to the technical field related to printing equipment, in particular to a transition paper feeding structure. Background Art

[0002] In the hot stamping or printing industry, it is necessary to observe the hot stamping situation from time to time and make timely adjustments. If the feeding direction of the raw materials deviates during the feeding process, the hot stamping pattern will be skewed, and the final product quality will be poor.

[0003] There is a paper feeding device for a cigarette making machine and a paper tension control method. The paper feeding device includes a paper coil output mechanism, a paper pulling roller, a paper feeding roller and a plurality of paper guide rollers. A tensioning mechanism for providing tension to the paper tape is provided on the paper tape conveying path between the paper pulling roller and the paper feeding roller. The tensioning mechanism includes a horizontally arranged tensioning roller for cooperating with the paper tape. The tensioning roller is connected to a guide rod for guiding its vertical movement and acts freely on the paper tape by gravity, so as to maintain the stability of the tension of the paper tape by the up and down floating of the tensioning roller.

[0004] The tensioning adjustment of the tensioning roller relies on the mechanism to adjust, and the speed of the paper guide roller needs to be adjusted at the same time. That is to say, the tensioning roller is tensioned in a graded manner and is only turned on when tensioning is needed. It cannot be finely adjusted through real-time changes in raw materials.

[0020] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered thereon. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may also be an element centered thereon. When the number of an element is referred to as having "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings:

[0024] like Figure 1-2 As shown, in this embodiment, a transitional paper feeding structure is provided, including a mounting base 11. A paper guide roller 6 is rotatably connected to the mounting base 11. The paper guide roller 6 is used for laminating and feeding paper. An adjustment assembly is also mounted within the mounting base 11. The adjustment assembly is equipped with a tensioning roller 1. The tensioning roller 1 is connected to the mounting base 11 in a stepless sliding manner via the adjustment assembly. The adjustment assembly can be manually controlled by a worker to steplessly adjust the tensioning roller 1 up and down, specifically, to move the tensioning roller 1 away from or closer to the paper guide roller 6.

[0025] In this embodiment, the adjustment assembly includes an adjusting rod 2 and a pair of symmetrically arranged screw rods 3. The screw rod 3 is rotatably connected to the mounting seat 11. The adjusting rod 2 is transmission-connected to the screw rod 3. A movable seat 7 is threadedly provided on the screw rod 3. The ends of the tensioning roller 1 are respectively rotatably connected to the movable seat 7. The rotation of the screw rod 3 will cause the movable seat 7 to move up and down relative to the mounting seat 11.

[0026] A pair of symmetrically arranged bearing seat groups 9 are provided in the mounting seat 11, and the screw rod 3 is rotatably connected to the mounting seat 11 through the bearing seat groups 9. In order to enable the movable seat 7 to withstand the weight of the tensioning roller 1 and the tension of the raw material during movement, two parallel guide rods 8 are fixedly installed between the pair of bearing seat groups 9 on the same side. These two guide rods 8 pass through the movable seat 7 together, and the movable seat 7 can move up and down along the guide rods 8. In addition, the guide rods 8 can eliminate the lateral force received by the movable seat 7 to prevent the movable seat 7 from moving laterally.

[0027] The mounting base 11 includes a front side plate and a rear side plate. The mounting base 11 also includes an adjusting rod 2 mounting plate installed at the bottom ends of the two side plates. The adjusting rod 2 mounting plate is mainly used to carry the adjusting rod 2 that can rotate freely relative to the mounting base 11.

[0028] In this embodiment, one end of the adjusting rod 2 passes through the mounting seat 11 and is fixedly provided with a handwheel 10, so that a worker can control the rotation of the adjusting rod 2 through the handwheel 10. The handwheel 10 is fixed to the adjusting rod 2, so when the handwheel 10 rotates, the adjusting rod 2 also rotates.

[0029] In this embodiment, a first gear 4 is fixed to the bottom end of the screw rod 3. A pair of second gears 5 are fixed to each side of the adjusting rod 2 near the end, meshing with the first gear 4 and the second gear 5. Rotation of the adjusting rod 2 transfers torque to the first gear 4 of the screw rod 3 via the second gear 5, causing the screw rod 3 to rotate. The rotation of the screw rod 3 controls the reciprocating movement of the movable base 7 on the mounting base 11. Because of the gear control, the movement of the tensioning roller 1 can be controlled steplessly.

[0030] To further elaborate, two paper guide rollers 6 are positioned above the active tensioning roller 1. After the stock is attached to one of the guide rollers 6, it wraps around the side of the adjustment roller and then moves to the second guide roller 6 for attachment. When tensioning is required or the hot stamping pattern on the stock needs to be better viewed, the tensioning roller 1 is moved downward, lowering the stock and tensioning it to better display the pattern for workers to observe. When there is no excess material coming out or the stock is well-tensioned, the tensioning roller 1 can be moved upward or left unchanged to ensure smooth feeding of the material (stock).

[0031] The technical features of the above-described embodiments can be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there are no contradictions in the combination of these technical features, they should be considered to be within the scope of this specification. For those skilled in the art, without departing from the concept of the utility model, they can also make several variations and improvements, which fall within the scope of protection of the utility model. Therefore, the scope of protection of this utility model patent shall be based on the appended claims.
