DETAILED DESCRIPTION

[0027] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.

[0028] like Figures 1 to 3 As shown, this embodiment provides a pushing mechanism for sealing a box, comprising:

[0029] A mounting seat 11, on which a cam 12 is rotatably mounted;

[0030] A driving member, which is disposed in the mounting seat 11 and is used to drive the cam 12 to rotate;

[0031] A linear motion mechanism 14, which is disposed on the mounting seat 11, a moving plate 15 of the linear motion mechanism 14 is hinged to the cam 12 via a first connecting member 16, and a push block 17 is mounted on the moving plate 15;

[0032] The rotating mechanism 18 has a swing arm 19, which is arranged on the mounting seat 11 through a rotating shaft 21, and a pressing plate 13 is arranged at the end of the swing arm 19; a transmission arm 22 is fixed on the rotating shaft 21;

[0033] The transmission assembly 23 includes a contact piece 24, a second connecting piece 25 and a reciprocating mechanism 26. The contact piece 24 is mounted on the mounting seat 11 through the reciprocating mechanism 26. The contact piece 24 is tightly pressed against the curved surface of the cam 12. One end of the second connecting piece 25 is hinged to the contact piece 24, and the other end of the second connecting piece 25 is hinged to the transmission arm 22.

[0034] The technical effect of this solution is that a driving member can drive the push block 17 and the swing arm 19 to work at the same time, which can effectively reduce the equipment cost. The driving member can be a combination of a servo motor and a reducer, or a servo motor or a rotary cylinder. The application scope of the box sealing pushing mechanism of this solution is not limited to a certain type of paper box. In specific use situations, it can achieve bending and sealing of different paper boxes by cooperating with an external auxiliary mechanism.

[0035] In this solution, a driving member is used to simultaneously control the movement of the two working ends. The working principle of the push block 17 and the swing arm 19 when working is described below:

[0036] The driving member works and drives the cam 12 to rotate. The cam 12 controls the movement of the movable plate 15 through the first connecting member 16, thereby realizing the movement of the push block 17, which is used to bend the cardboard on the flange of the paper box. After completing a single operation, the cam 12 and the push block 17 are reset.

[0037] When the cam 12 rotates, it pushes the abutment 24 to move, and the abutment 24 pushes the transmission arm 22 to move through the second connecting member 25. At this time, the rotating shaft 21 drives the swing arm 19 to rotate, which is used to bend the cardboard on the flange of the paper box. After completing a single operation, the cam 12 and the swing arm 19 are reset.

[0038] As an implementation of this embodiment, the mounting seat 11 has an extension plate 27 , and the extension plate 27 is used to mount the reciprocating mechanism 26 and the rotating shaft 21 .

[0039] As an implementation of this embodiment, a mounting groove 28 is provided on the mounting seat 11, and the mounting groove 28 is used to install the driving member. The driving member is not shown in the drawings.

[0040] As an implementation of this embodiment, the linear motion mechanism 14 also includes a first guide mechanism 29, the first guide mechanism 29 includes a first guide rail 30 and a first slider 31, the first slider 31 is installed on the mounting seat 11 through the first guide rail 30, and the first slider 31 is fixed on the movable plate 15.

[0041] In this solution, the first guide mechanism 29 is in the form of a combination of a first guide rail 30 and a first slider 31, so as to enable the movable plate 15 to perform linear reciprocating motion.

[0042] Furthermore, a fixed plate is installed on the movable plate 15 through a column, and a push block 17 is installed on the fixed plate.

[0043] As an implementation mode of this embodiment, the reciprocating mechanism 26 includes a second guide rail 32, a second slider 33, a fixed block 34, a moving block 35 and an elastic member 36. The second slider 33 is installed on the extension plate 27 through the second guide rail 32, the moving block 35 is fixed on the second slider 33, the fixed block 34 is fixed on the extension plate 27, the moving block 35 and the fixed block 34 are connected by an elastic member 36, and the abutment member 24 is fixed on the moving block 35.

[0044] Furthermore, the elastic member 36 is a spring. In this solution, the elastic member 36 is used to push the moving block 35, so as to ensure that the abutting member 24 and the circumferential surface of the cam 12 are tightly abutted, and the cam 12 can effectively drive the abutting member 24.

[0045] Furthermore, the abutting member 24 includes an abutting wheel 37 . The abutting wheel 37 is provided at one end of the abutting member 24 facing the cam 12 , and a curved surface of the abutting wheel 37 contacts a curved surface of the cam 12 .

[0046] As an implementation of this embodiment, the first connecting member 16 and / or the second connecting member 25 are telescopic members, and the telescopic members further use one-way cylinders or two-way cylinders. By adjusting the first connecting member 16 and / or the second connecting member 25, it is possible to adapt to the sealing of packaging boxes of different sizes.

[0047] like Figure 4 As shown, the number of the pushing mechanisms for sealing the box in this solution is two, and the working principles of the two pushing mechanisms are the same, but the structures of the two pushing mechanisms are in a mirror image relationship.

[0048] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
