[0034] The baler is a circulating baling machine applicable to small agricultural machinery, and is particularly used for baling long vegetables such as lettuce and automatically packing them into boxes. The baler is mainly composed of a baling part and a box packing part, and a single motor is used to drive the translation mechanism 3, so that the baling and box packing functions can be completed within one motion cycle, which reduces the size and complexity of the machine while ensuring complete functions, so that the baler can also be used in small agricultural machinery.

[0035] Embodiment 2: A preferred embodiment of the utility model provides a small-scale circulation baler, which differs from the above-mentioned embodiment only in that: the translation mechanism 3 includes a translation rack 31 arranged on the frame 1, a push block 32 arranged above the translation rack 31 and a driving motor 33 for driving the translation rack 31 to move, and the output shaft of the driving motor 33 is connected to a gear meshing with the translation rack 31, so that the gear can be driven to rotate by the driving motor 33, thereby driving the translation rack 31 and the push block 32 to perform translational movement.

[0036] In this embodiment, the translation rack 31 is preferably provided with two groups, and the two groups of translation racks 31 are symmetrically arranged on both sides of the funnel 2. The push block 32 includes moving blocks 321 respectively arranged on the translation rack 31 and a connecting block 322 connecting the two groups of moving blocks 321. The connecting block 322 is provided with a hollow cavity for the packaging film to pass through, so that the free end of the packaging film passes through the connecting block 322 and is connected to the fixed clamp 4, and after the fruits and vegetables to be packaged are loaded, the packaging film is retracted toward the fixed clamp 4 along with the translation mechanism 3.

[0037] Embodiment 3: A preferred embodiment of the present invention provides a small-scale circulation baling machine, which differs from the above-mentioned embodiments only in that: a fixing rod 6 for mounting a baling film roll is provided on the frame 1 to facilitate fixing of the baling film roll.

[0038] Embodiment 4: A preferred embodiment of the utility model provides a small-scale circulation baling machine, which differs from the above-mentioned embodiments only in that: the funnel 2 is rotatably connected to the frame 1 through a rotating shaft 7, an inclined plate 21 is provided in the funnel 2 and is inclined downward in the direction of the fixed clamp 4, a protrusion 22 is provided on the side of the funnel 2, and an elastic member 23 is provided between the protrusion 22 and the frame 1 to keep the inclined plate 21 inclined downward in the direction of the fixed clamp 4 in the initial state; a special-shaped cam 8 is rotatably connected to the push block 32, and a torsion spring is provided between the special-shaped cam 8 and the push block 32 to limit the position of the special-shaped cam 8.

[0039] In this embodiment, the shape of the special-shaped cam 8 is preferably an arc-shaped semi-arc rod. Before packaging is completed, the special-shaped cam 8 abuts against the protrusion 22 and supports the protrusion 22; as the translation mechanism 3 moves, the special-shaped cam 8 bypasses the protrusion 22, and after the protrusion 22 loses support, the funnel 2 is forced to flip over to complete the packaging.

[0040] The specific working process of a small cycle baler:

[0041] (1) Initial state: The translation mechanism 3 is located at one end close to the packing film roll. The free end of the packing film roll passes through the pushing block 32 and is fixed by the fixing clip 4.

[0042] (2) Loading state: Put the lettuce in, and the lettuce and the packing film enter the funnel 2 together;

[0043] (3) Packing state: The driving motor 33 works to drive the gear to rotate. The gear drives the translation rack 31 and the pushing block 32 to move translationally towards the fixing clip 4, so as to gather the packing film towards the fixing clip 4, and the lettuce is packed into bundles;

[0044] (4) Heating and fusing state: The heating mechanism 5 works to fuse and thermoplastically bond the two layers of packing film, thus completing the packing operation;

[0045] (5) Boxing state: It is realized by the cooperation of the convex part 22 provided on the side of the funnel 2 and the special-shaped cam 8 of the pushing block 32. That is, before the packing is completed, the special-shaped cam 8 abuts against and supports the convex part 22; as the translation mechanism 3 moves, the special-shaped cam 8 bypasses the convex part 22. After the convex part 22 loses support, at this time, several packed lettuces will be flipped from the inclined funnel 2, and several packed lettuces will slide into the collection box in the lower right, and then the boxing work is completed.

[0046] Those skilled in the art can easily understand that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
