Non-dry adhesive label station paper conveying buffer device

Abstract

This invention relates to the field of labeling machine technology, specifically to a label paper conveying and buffering device for self-adhesive labeling stations. It includes a fixed base, within which a drive motor is housed. The output shaft of the drive motor extends upward through the fixed base, and a drive roller is coaxially connected to the output shaft. A driven roller, connected to the drive roller, and a pressure roller, cooperating with the drive roller, are vertically mounted on the fixed base. A fixed plate, with its cross-section facing both the drive roller and the driven roller, is mounted on the fixed base. A sliding rod is vertically mounted on the fixed plate, and a shaped baffle is horizontally mounted at the bottom end of the sliding rod, with its side extending to the cross-section. An air blowing pipe is vertically mounted on the fixed base on the side of the pressure roller adjacent to the shaped baffle, with air blowing holes on the side facing the driven roller. The shaped baffle, in cooperation with the fixed base, restricts the label paper, preventing it from swaying with the airflow after spreading. Simultaneously, the height of the shaped baffle can be adjusted via the sliding rod to accommodate labels of different heights.

Description

Technical Field

[0001] This invention relates to the field of labeling machine technology, and in particular to a label paper conveying buffer device for self-adhesive labeling stations. Background Technology

[0002] Self-adhesive labeling stations mainly consist of label rolls, unwinding mechanisms, label conveying mechanisms, and label peeling mechanisms. The label conveying mechanism includes a label feeding power roller group, a label paper conveying buffer device, and a label receiving power roller group. Most existing label paper conveying buffer devices adopt airflow buffering. In practice, airflow is used to blow the label paper, thereby spreading the label paper into an arc shape to form a buffer. However, after the label paper is spread out under the action of airflow, it is easy to shake with the airflow, resulting in unstable label paper conveying. Summary of the Invention

[0003] To address the above problems, embodiments of the present invention provide a label paper conveying buffer device for self-adhesive label stations.

[0004] In one aspect of this invention, a label conveying buffer device for self-adhesive label stations is provided, comprising a fixed base, a drive motor disposed within the fixed base, the output shaft of the drive motor extending upward through the fixed base, and a drive roller coaxially connected to the output shaft; a driven roller and a pressure roller cooperating with the drive roller are vertically disposed on the fixed base; a fixed plate is disposed on the fixed base with its cross-section facing both the drive roller and the driven roller; a sliding rod is vertically disposed on the fixed plate; a shaped baffle is horizontally disposed at the bottom end of the sliding rod; the side of the shaped baffle extends to the cross-section position; an air blowing pipe is vertically disposed on the fixed base on the side of the pressure roller adjacent to the shaped baffle; an air blowing hole is disposed on the side of the air blowing pipe facing the driven roller; the shaped baffle, the fixed plate, and the fixed base constitute a buffer space.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: the addition of an irregularly shaped baffle, which cooperates with the fixed base to restrict the label paper and prevent it from shaking with the airflow after it is spread out under the action of the airflow; at the same time, the height of the irregularly shaped baffle can be adjusted by the sliding rod to accommodate labels of different heights.

[0006] Optionally, rubber rings are spaced apart on the surfaces of both the drive roller and the driven roller, and a transmission groove is formed between adjacent rubber rings. A transmission belt is provided between the transmission grooves at the same horizontal height between the drive roller and the driven roller.

[0007] Optionally, a sleeve is provided on the side of the fixing plate, and a threaded hole is provided on the side wall of the sleeve. A locking screw is provided in the threaded hole, and the sliding rod is inserted into the sleeve and fixed by the locking screw.

[0008] Optionally, a roller brush and a redirecting roller that cooperates with the roller brush are vertically arranged on the side of the fixed plate near the air blowing pipe on the fixed base. Attached Figure Description

[0016] The components include: fixed base 1, drive motor 2, drive roller 3, driven roller 4, pressure roller 5, fixed plate 6, sliding rod 7, irregular baffle 8, air pipe 9, air hole 10, arc-shaped retaining sleeve 11, rubber ring 12, transmission belt 13, sleeve 14, locking screw 15, roller brush 16, and redirecting roller 17. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0018] See Figures 1-5The label conveying buffer device for self-adhesive labeling stations provided in this embodiment of the invention includes a fixed base 1, a drive motor 2 is installed inside the fixed base 1, the output shaft of the drive motor 2 extends upward through the fixed base 1, and a drive roller 3 is coaxially connected to the output shaft. A driven roller 4 and a pressure roller 5 that cooperate with the drive roller 3 are vertically installed on the fixed base 1. A fixed plate 6 is installed on the fixed base 1 with its cross-section facing both the drive roller 3 and the driven roller 4. A sliding rod 7 is vertically installed on the fixed plate 6. A shaped baffle 8 is horizontally installed at the bottom end of the sliding rod 7. The side of the shaped baffle 8 extends to the cross-section position. An air blowing pipe 9 is vertically installed on the fixed base 1 on the side of the pressure roller 5 near the shaped baffle 8. An air blowing hole 10 is installed on the side of the air blowing pipe 9 facing the driven roller 4. The shaped baffle 8, the fixed plate 6 and the fixed base 1 form a buffer space.

[0019] In practice, an arc-shaped baffle 11 can be fitted onto the air blowing pipe 9. The two vertical sides of the opening of the arc-shaped baffle 11 are located on both sides of the air blowing hole 10. The arc-shaped baffle 11 has a certain thickness so that it can play a guiding role.

[0020] Rubber rings 12 are spaced apart on the roller surfaces of both the drive roller 3 and the driven roller 4. A transmission groove is formed between adjacent rubber rings 12. A transmission belt 13 is provided between the transmission grooves at the same horizontal level between the drive roller 3 and the driven roller 4. The rubber rings 12 separate the label on the label paper from the roller surfaces of the drive roller 3 and the driven roller 4. The spaced rubber rings 12 achieve incomplete contact with the label, effectively preventing the label from getting tangled on the drive roller 3 or the driven roller 4.

[0021] A sleeve 14 is provided on the side of the fixing plate 6. A threaded hole is provided on the side wall of the sleeve 14. A locking screw 15 is provided in the threaded hole. The sliding rod 7 is inserted into the sleeve 14 and fixed by the locking screw 15. The height of the irregular baffle 8 can be easily adjusted by the sliding rod 7 through the adjustment mechanism of the sleeve 14 and the locking screw 15, so as to adapt to the label paper of different heights.

[0022] A roller brush 16 and a redirecting roller 17 that cooperate with the roller brush 16 are vertically arranged on the side of the fixed plate 6 near the air pipe 9 on the fixed base 1.

[0023] See Figure 6 The arrow indicates the direction of the label paper. The label paper enters the conveying buffer device from the driven roller 4 side, travels to the drive roller 3, and is redirected into the buffer space by the pressure roller 5. Under the action of the airflow blown out by the air pipe 9, it spreads out in an arc shape and returns to the redirecting roller 17 and roller brush 16 for output.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
