Description

Technical Field

[0001] The utility model relates to paper processing, in particular to a paper biting mechanism of a card mounting machine. Background Art

[0002] A card laminating machine is a special device that can paste paper or other materials on cardboard to improve its appearance and protective performance. The paper biting mechanism is mainly used to bite and fix the cardboard, thereby facilitating the subsequent laminating operation. Chinese patent document (publication number: CN102795045A; publication date: November 28, 2012) discloses a paper biting mechanism of a cardboard laminating machine, including a paper biting piece, a paper biting seat and a paper biting body, the paper biting body is installed in a groove on a paper biting roller through a tooth shaft, and is characterized in that the paper biting body has a flange, the paper biting seat is installed on the flange with a pin shaft as the rotation axis, a spring is provided between one end of the paper biting seat and the tooth body, and a screw is provided on the tooth seat, the screw is arranged above the spring, the paper biting piece is installed above the other end of the paper biting seat through a bolt, and the bolt head of the bolt is exposed to the upper end surface of the paper biting piece.

[0003] The defects of the above structure are: the bite paper piece and the bite paper seat are split structures and connected by bolts. Although this structure can facilitate the disassembly and assembly of the bite paper piece, the strength of the single bite paper piece itself is relatively poor, which makes the bite paper piece very easy to be damaged; in addition, after a period of use, the spring is also easily damaged, but the above structure can only replace the spring through the groove. Since the specifications of the groove are generally small, the replacement operation of the spring is very inconvenient. If it cannot be replaced, the entire bite paper body can only be removed and the spring can be replaced, which is very troublesome. Utility Model Content

[0004] In view of the shortcomings of the background technology, the technical problem to be solved by the utility model is to provide a paper biting mechanism of a card mounting machine for solving the above-mentioned problem.

[0005] To this end, the utility model is implemented by adopting the following scheme:

[0006] The paper-biting mechanism of the card mounting machine is characterized in that it includes a paper-biting roller, a paper-biting seat arranged in a groove on the paper-biting roller, the paper-biting seat is integrally provided with a paper-biting portion that can cooperate with the paper-biting roller, the paper-biting seat is rotatably arranged on a connecting seat, a spring is arranged between one end of the paper-biting seat and the connecting seat, the connecting seat is slidably connected to the base, and the base is connected to a rotating shaft.

[0007] The paper biting seat is provided with a limiting protrusion on one side corresponding to the paper biting portion and can abut against the connecting seat.

[0008] The bottom of the connecting seat is provided with a dovetail portion, and the base is provided with a dovetail groove for inserting the dovetail portion.

[0009] The connecting seat is fixed on the base through a fastener.

[0010] The paper bite seat is provided with a clearance hole corresponding to the fastener.

[0011] An adjusting bolt is screwed onto the paper biting seat, and one end of the spring is tightly pressed onto the adjusting bolt.

[0012] The paper biting mechanism of the card mounting machine of the above technical solution has a simple structure and a reasonable design. By designing the paper biting seat and the paper biting part as an integrated structure, the paper biting part cooperates with the paper biting roller to bite the paper, which can effectively improve the strength of the paper biting part, thereby improving its service life and the stability of the paper biting part in cooperating with the paper biting. At the same time, by setting the paper biting seat on the connecting seat, and sliding the connecting seat on the base, when the paper biting seat or the spring needs to be replaced, the paper biting seat can be directly pulled out from the base, making the subsequent replacement operation more convenient.

[0019] As shown in the figure, the paper-biting mechanism of the card mounting machine disclosed in the utility model comprises a paper-biting roller 1, a paper-biting seat 5 arranged at a groove 3 on the paper-biting roller 1, a paper-biting portion 4 which can cooperate with the paper-biting surface 2 on the paper-biting roller 1 is integrally arranged on the paper-biting seat 5, the paper-biting seat 5 is rotatably arranged on the connecting seat 9, a spring 10 is arranged between one end of the paper-biting seat 5 and the connecting seat 9, the connecting seat 9 is slidably connected to the base 7, and the base 7 is connected to the rotating shaft 6. Further, the paper-biting seat 5 is provided with a limiting protrusion 14 which can abut against the connecting seat 9 on one side corresponding to the paper-biting portion 4, so as to limit the swing angle of the paper-biting seat 5. A dovetail portion 8 is arranged at the bottom of the connecting seat 9, and a dovetail groove 15 for inserting the dovetail portion 8 is arranged on the base 7. By setting such a dovetail structure, the plug-in connection between the connecting seat 9 and the base 7 can be realized. In addition, the connecting seat 9 is fixed to the base 7 by a fastener 12. After the connecting seat 9 and the base 7 are inserted into place, they are fixed to the base by the fastener 12, which is convenient for the subsequent paper biting action. The paper biting seat 5 is provided with a clearance hole 13 corresponding to the fastener 12. When the fastener 12 is tightened, the fastener 12 can be rotated through the clearance hole 13 by a screwdriver to fix the connecting seat 9 on the base 7. Loosening the fastener 12 allows the connecting seat 9 to slide with the base 7, and the parts above the connecting seat 9 can be taken out as a whole for easy replacement. The paper biting seat 5 is screwed with an adjusting bolt 11, and one end of the spring 10 is pressed tightly on the adjusting bolt 11. By rotating the adjusting bolt 11, the position of the adjusting bolt 11 can be changed, and the spring 10 can be squeezed to change its length, thereby changing the elastic force applied by the spring 10, so that the size of the paper biting force of the paper biting part 4 and the paper biting roller 1 can be adjusted.

[0020] The working principle of the utility model is: when the paper jam is sent to the paper biting roller 1, by controlling the rotation of the rotating shaft 6, the base 7 and the paper biting seat 5 can be driven to swing, the paper biting part 4 on the paper biting seat 5 will cooperate with the paper biting surface 2 on the paper biting roller 1, and due to the presence of the spring 10, the paper jam is elastically bitten between the paper biting part 4 and the paper biting surface 2 for positioning, and the paper jam can be mounted at this time; when the mounting is completed, the rotating shaft 6 is controlled to reverse, driving the base 7 and the paper biting seat 5 to swing in the opposite direction, so that the paper biting part 4 is separated from the paper jam, and the paper jam is loosened.

[0021] This structure of the utility model, by designing the paper bite seat and the paper bite part as an integrated structure, the paper bite part cooperates with the paper bite roller to bite the paper, which can effectively improve the strength of the paper bite part, thereby improving its service life and the stability of the paper bite part in cooperating with the paper bite. At the same time, by setting the paper bite seat on the connecting seat, and slidably setting the connecting seat on the base, when the paper bite seat or the spring needs to be replaced, the fastener 12 can be loosened first, and then the rotating shaft 6 can be rotated to make the paper bite seat 5 as much as possible exposed in the groove 3, and then the paper bite seat 5 can be held tightly. Due to its sliding connection, it can be pulled out from the base 7 through the connecting seat 9, making the subsequent replacement operation more convenient.
