[0033] See also Figures 1 to 4 As shown, a film joining mechanism provided in this embodiment includes a mounting frame 10, a first driving member 20, a moving member 30 and a clamping mechanism 40. The mounting frame 10 can be in a first position, and the first position is located outside the material 50 to be filmed and is parallel to the first film-to-be-filmed side surface 51 of the material 50 to be filmed; the moving member 30 is movably mounted on the mounting frame 10, the fixed end of the first driving member 20 is mounted on the mounting frame 10, the driving end of the first driving member 20 is connected to the moving member 30, and the first driving member 20 is configured to drive the moving member 30 to reciprocate along the mounting frame 10; the clamping mechanism 40 is arranged on the moving member 30, and the clamping mechanism 40 is configured to clamp or release the head end of the film material 60; when the mounting frame 10 is in the first position, the first driving member 20 drives the moving member 30 to move along the first horizontal direction ( Figure 2 The clamping mechanism 40 moves in the X direction to drive the film material 60 clamped by the clamping mechanism 40 to move along the first horizontal direction and completely surround the first side surface 51 of the material 50 to be filmed.

[0034] Specifically, the moving member 30 is a square frame structure, and the moving member 30 can be slidably mounted on the mounting frame 10 along the first horizontal direction through a sliding pair composed of a linear guide rail and a slider.

[0035] Specifically, the first driving member 20 uses a driving motor, a synchronous pulley and a synchronous belt to form a driving module, which has the advantages of precise stroke control and stable and reliable operation.

[0036] It can be seen that through the cooperation of the mounting frame 10, the first driving member 20, the moving member 30 and the clamping mechanism 40, the automatic film wrapping of the first film-to-be-wrapped side 51 of the film-to-be-wrapped material 50 is achieved, thereby improving the film wrapping efficiency and saving manpower.

[0037] As an embodiment, the film joining mechanism further includes a second driving member 70, the fixed end of the second driving member 70 is mounted on the moving member 30, the driving end of the second driving member 70 is connected to the clamping mechanism 40, and the second driving member 70 is configured to drive the clamping mechanism 40 along the second horizontal direction ( Figure 2 The first horizontal direction is perpendicular to the second horizontal direction; after the film material 60 clamped by the clamping mechanism 40 completely surrounds the first side surface 51 of the material 50 to be filmed, the second driving member 70 drives the clamping mechanism 40 to move along the second horizontal direction, so as to drive the film material 60 clamped by the clamping mechanism 40 to move along the second horizontal direction and surround part or all of the second side surface 52 of the material 50 to be filmed, and the second side surface 52 to be filmed is perpendicular to the first side surface 51 to be filmed.

[0038] Specifically, the second driving member 70 is a cylinder.

[0039] It should be noted that before the second driving member 70 drives the clamping mechanism 40 to move along the second horizontal direction, the clamping mechanism 40 needs to be moved to the outside of the second film-wrapped side surface 52 of the material 50 to be film-wrapped in the first horizontal direction.

[0040] It can be seen that by setting the second driving member 70, after the film material 60 clamped by the clamping mechanism 40 completely surrounds the first side surface 51 to be filmed of the material 50 to be filmed, the film material 60 clamped by the clamping mechanism 40 is driven by the second driving member 70 to move along the second horizontal direction, so that the second side surface 52 to be filmed of the material 50 to be filmed can be partially or completely filmed, thereby further improving the filming efficiency.

[0041] As an embodiment, the film joining mechanism also includes a third driving member (not shown in the figure), the mounting frame 10 is hinged on the column 80 of the hydraulic baler, and the fixed end of the third driving member is installed on the column 80 of the hydraulic baler. The material 50 to be filmed is the material compressed by the hydraulic baler. The driving end of the third driving member is connected to the mounting frame 10, and the third driving member is configured to drive the mounting frame 10 to approach or move away from the material 50 to be filmed, so that the mounting frame 10 moves alternately to the first position and the second position.

[0042] Specifically, the mounting frame 10 is rotatably hinged to a column 80 on a non-operating side of the hydraulic baler via a hinge shaft 11 .

[0043] It can be seen that by hingedly connecting the mounting frame 10 to the column 80, it is achieved that after the material is filmed, the film connection mechanism is turned away from the material to avoid the material from being moved to the next process.

[0044] As an embodiment, the clamping mechanism 40 includes a base 41, a first clamping member 42 and a second clamping member 43, wherein: the base 41 is vertically arranged on the movable member 30 and can be moved along the second horizontal direction, the first clamping member 42 and the second clamping member 43 are installed on the base 41 at intervals in the height direction, the driving end of the second driving member 70 is connected to the base 41, the first clamping member 42 is located below the second clamping member 43, and the first clamping member 42 and the second clamping member 43 are both configured to clamp the ends of the film material 60.

[0045] It can be seen that by providing the first clamping member 42 and the second clamping member 43 , the end of the film material 60 is stably clamped to ensure the reliability of clamping the film material 60 .

[0046] As an embodiment, the first clamping member 42 and the second clamping member 43 each include a rotating driving member 44 and a pneumatic clamp 45, the fixed end of the rotating driving member 44 is mounted on the base 41, the driving end of the rotating driving member 44 is connected to the pneumatic clamp 45, and the rotating driving member 44 is configured to drive the pneumatic clamp 45 to rotate a preset angle to adjust the clamping direction of the pneumatic clamp 45.

[0047] Specifically, the rotary driving member 44 is a rotary cylinder.

[0048] It can be seen that by setting the rotary drive member 44, the clamping direction of the pneumatic clamp 45 can be adjusted to suit different application scenarios, with good compatibility and convenience for film wrapping.

[0049] As an embodiment, the first clamping member 42 and the second clamping member 43 further include a detection member 46 , which is configured to detect whether the end of the film material 60 is located at the clamping position of the pneumatic clamp 45 to control the pneumatic clamp 45 to clamp the end of the film material 60 .

[0050] Specifically, the detection member 46 is arranged on one side of the pneumatic clamp 45, and the detection member 46 includes a transmitting part and a receiving part. When the end of the film material 60 is located between the transmitting part and the receiving part, the normal signal reception of the transmitting part and the receiving part is blocked to detect whether the end of the film material 60 is located at the clamping position of the pneumatic clamp 45.

[0051] It can be seen that the detection member 46 can ensure that the first clamping member 42 and the second clamping member 43 can accurately and reliably clamp the end of the film material 60 to avoid empty clamping or film material detachment.

[0052] As an implementation manner, the pneumatic clamping jaw 45 is horizontally arranged, and the first clamping member 42 and the second clamping member 43 are both configured to clamp the vertical edges of the ends of the film material 60 .

[0053] It should be noted that the film joining mechanism proposed in this embodiment can also be used for the lateral film surrounding of other non-compressed materials.
