Description

Technical Field

[0001] The utility model relates to a product taking machine, in particular to a positioning mechanism for paper cup sheets. Background Art

[0002] The Chinese utility model patent with the publication number of CN218201370U discloses a product taking machine. The paper blocking frame is provided with a tilted paper blocking arm, which can adapt to semi-finished paper stacks with different stacking heights. However, when the semi-finished paper stack is a paper cup sheet, the front and rear edges of the paper stack are curves. It is necessary to additionally provide processed clamping blocks with curved edges to ensure that the semi-finished paper stack can be accurately limited within the paper blocking frame. However, with the change of the paper cup specifications, the curvature of the curve also changes accordingly, and it is necessary to manufacture clamping blocks with various curvatures to adapt, resulting in high costs and cumbersome processing. Content of the Utility Model

[0003] In view of the technical problems existing in the background art, the utility model aims to provide a positioning mechanism for paper cup sheets, which is provided with adjustable front and rear paper blocking members to adapt to the edges of paper stacks with different curvatures.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: The positioning mechanism for paper cup sheets includes an operation platform, and a paper blocking frame is arranged on the operation platform. The paper blocking frame includes a front paper blocking board, a rear paper blocking board, a left paper blocking board and a right paper blocking board. Among them, a front paper blocking member is arranged on the front paper blocking board in a front-back moving and adjustable manner, and a rear paper blocking member is arranged on the rear paper blocking board in a front-back moving and adjustable manner. The front paper blocking member and the rear paper blocking member are arranged facing each other. The front paper blocking member and the rear paper blocking member are both distributed in the left-right direction, and the front paper blocking member and the rear paper blocking member cooperate to limit the semi-finished paper stack in the front-back direction.

[0005] In this scheme, by moving the front and rear paper blocking members back and forth to adjust for the edges of paper stacks with different curvatures, the semi-finished paper stack can be accurately limited within the paper blocking frame, and making the front and rear paper blocking members flush can adapt to straight edges.

[0006] Preferably, positioning holes are distributed in the left-right direction on both the rear paper blocking board and the front paper blocking board. The front paper blocking member and the rear paper blocking member are both provided with sliding grooves, and fasteners pass through the sliding grooves and are connected to the positioning holes.

[0007] In this scheme, for the edges of paper stacks with different wavelengths, the positioning holes corresponding to the fasteners are changed, so that the front paper blocking member and the rear paper blocking member can correspond to the wave crests of the curved edges and make sufficient contact. For the edges of paper stacks with different amplitudes, the front and rear paper blocking members are moved back and forth to adjust, so that the front paper blocking member and the rear paper blocking member are accurately in contact with the semi-finished paper stack.

[0008] Preferably, the rear paper baffle is connected to a mounting seat via an elastic member, the mounting seat is connected to the left paper baffle, a force block is provided on the rear paper baffle, a cam member is rotatably provided on the mounting seat, and the cam member cooperates with the force block to drive the rear paper baffle to approach or move away from the mounting seat.

[0009] In this scheme, after the front side of the semi-finished paper pile is aligned with the front paper stopper and the right side is aligned with the right paper stopper of the right paper stopper, the cam part is rotated to drive the rear paper stopper to overcome the elastic force of the elastic part and move away from the mounting seat, so that the rear paper stopper is close to the rear side of the semi-finished paper pile.

[0010] Preferably, the cam member is connected to a handle.

[0011] This solution is convenient for operators to operate.

[0012] Preferably, the front paper stopper and the rear paper stopper both comprise a paper stopper seat and a movable block, the movable block is arranged on the paper stopper seat for lifting and lowering adjustment, and the movable block has a paper stopper surface.

[0013] In this solution, the lifting and lowering adjustment movable block can adapt to semi-finished paper piles of different thicknesses to ensure the contact area.

[0014] Preferably, the movable block is provided with a limiting groove, the limiting groove is arranged in the vertical direction, and the paper stopper is provided with a limiting block, and the limiting block cooperates with the limiting groove.

[0015] In this solution, the limit groove guides the lifting and lowering adjustment of the movable block through the limit block, ensuring that the paper blocking surface of the movable block does not deviate and fully contacts the edge of the semi-finished paper pile.

[0016] Preferably, the left paper stopper and the right paper stopper are both provided with a rotating shaft, one end of the rotating shaft is provided with a paper stopper arm, and the other end of the rotating shaft is transmission-connected with a driving member, and the driving member drives the rotating shaft to rotate.

[0017] In this solution, the driving member drives the rotating shaft to rotate and drives the paper stop arm to be raised or lowered to adapt to semi-finished paper piles of different thicknesses.

[0018] Preferably, a driving platform is longitudinally movable on the operating platform, the paper stop frame is transversely movable on the driving platform, the right paper stop is connected to the front paper stop, and the front paper stop and the rear paper stop are both connected to the left paper stop.

[0019] In this solution, the paper baffle moves horizontally on the operating platform, a semi-finished paper pile is placed at the paper placing station, and finished products and waste are separated at the waste clearing station.

[0020] The beneficial effects of the present utility model are as follows: for the edges of paper stacks with different wavelengths, the corresponding positioning holes of the fasteners are changed, so that the front paper blocking member and the rear paper blocking member can correspond to the wave peaks of the curved edges and have sufficient abutment. For the edges of paper stacks with different amplitudes, the front and rear paper blocking members are moved back and forth to adjust, so that the front paper blocking member and the rear paper blocking member accurately abut against the semi-finished paper stack. Therefore, the present utility model has substantial features and progress compared with the prior art. Description of the Drawings
