Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Please refer to fig. 1 to fig. 3. According to the utility model discloses carton side page or leaf preformer includes base 1, base lift actuating mechanism 2 and a pair of layering 3.

The surface of the base 1 is provided with a first limiting part 11 and a pair of second limiting parts 12. In the present embodiment, the first position-limiting portion 11 is composed of a pair of first position-limiting posts 111; the pair of second position-limiting portions 12 is a pair of second position-limiting posts.

The susceptor lift driving mechanism 2 is connected to the susceptor 1 to drive the susceptor 1 to ascend and descend. In this embodiment, the base lifting/lowering driving mechanism 2 is a cylinder, a push rod 21 of the cylinder 2 extends downward, and a lower end of the push rod 21 is connected to the base 1.

The upper ends of the pair of pressing strips 3 are hinged to the base 1 side by side. The hinge axis 10 of a pair of beads 3 is shown. The first limiting part 11 is located between the pair of pressing strips 3, and the inner sides of the pair of pressing strips 3 respectively abut against the first limiting part 11, so that the pair of pressing strips 3 are splayed. The pair of second limiting parts 12 are respectively located at the outer sides of the pair of pressing strips 3 to limit the outward rotation angle of the pair of pressing strips 3.

Preferably, the bottom end of each pressing strip 3 is provided with a pressing foot connected with the bottom end of the pressing strip, and the pressing foot is provided with a pressing part which is inclined outwards relative to the pressing strip 3 and extends downwards and is used for pressing the side page of the carton. The pressing part has the advantage that when the pair of side pages of the paper box inclines inwards, the pair of pressing strips 3 can push the pair of side pages of the paper box outwards smoothly.

In the example shown in the figure, a presser foot 4 is provided at the bottom end of each presser bar 3, and the presser foot 4 is in an inverted L shape, and the inverted L-shaped presser foot includes a horizontal edge portion 41 and a vertical edge portion 42. One end of the transverse edge part 41 is vertically connected with the bottom end of the pressing strip 3, the top end of the vertical edge part 42 is connected with the other end of the transverse edge part 41, and an included angle between the vertical edge part 42 and the transverse edge part 41 is an obtuse angle. The vertical edge portion 42 here functions as the above-described pressing portion, which is inclined outward and extends downward with respect to the bead 3. In other embodiments, the presser foot 4 may not be provided with the lateral edge portion 41, but only consist of the aforementioned vertical edge portion 42.

The utility model discloses carton side page or leaf pre-compaction mechanism's working process explanation is as follows.

As shown in fig. 1, in the initial state, the pair of compression beads 3 is drooped due to gravity, and is slightly opened due to the blocking of the pair of first limiting columns 111. In operation, as shown in fig. 2, the cylinder 2 is activated, and during the process that the push rod 21 of the cylinder 2 is pushed downwards, the pair of presser feet 4 arranged at the bottom ends of the pair of press strips 3 contact the pair of side leaves 94 of the paper box 9, and the pair of side leaves 94 of the paper box 9 are folded outwards. In this process, the pair of beads 3 are also rotated outward by the reaction force of the pair of side leaves 94. When the pair of pressing strips 3 are rotated outwards to abut against the pair of second limiting columns 12, as shown in fig. 3, the pair of pressing strips 3 cannot be opened continuously due to the blocking of the pair of second limiting columns 12, so that the pair of side leaves 94 of the carton 9 can be pressed continuously in a fixed posture until the push rod 21 of the cylinder 2 is completely extended, and thus the pair of side leaves 94 can be pressed to a larger angle, and the phenomenon that after the push rod 21 is retracted, the pair of side leaves 94 is turned back to the initial state to influence the operation of putting products into the carton 9 in the subsequent process is avoided.

Further, the position of the first limiting part 11 relative to the base 1 is adjustable along the horizontal direction; the position of each second stopper portion 12 relative to the base 1 is adjustable in the vertical direction.

In a specific embodiment, the base 1 defines a horizontal waist hole 13 and a pair of vertical waist holes 14, the pair of first position-limiting columns 111 are detachably mounted in the horizontal waist hole 13, and the pair of second position-limiting columns 12 are detachably mounted in the pair of vertical waist holes 14. The first and second position-

limiting columns

111 and 12 may be bolts, for example, which are fixed on the base 1 by nuts and can adjust the positions thereof in the waist holes.

The function of turning over a pair of side pages of the paper box towards the outer side can be realized only by adopting one air cylinder and a simple mechanical structure, and the paper box can adapt to packing boxes with different sizes by adjusting the positions of the first limiting part and the second limiting part.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
