DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1As shown, embodiment 1 is a conveying and cutting device, comprising a main conveyor belt 1 and an auxiliary conveyor belt 2 arranged in sequence, and the main conveyor belt 1 and the auxiliary conveyor belt 2 realize continuous conveying of materials. A fixed frame 3 is provided between the main conveyor belt 1 and the auxiliary conveyor belt 2, and the fixed frame 3 provides an installation support base for other components. A pressure wheel assembly 4 is provided at the end of the main conveyor belt 1, and a guide structure 5 that cooperates with the pressure wheel assembly is provided on the main conveyor belt 1. The guide structure 5 can gather the materials, especially those in a non-continuous state, and realize conveying guidance. The guide structure 5 and the pressure wheel assembly 4 are both arranged on the fixed frame 3. The pressure wheel assembly 4 can apply pressure to the material conveyed along the main conveyor belt 1, causing it to move in accordance with the main conveyor belt 1 to avoid confusion during cutting. A cutting mechanism 6 that cooperates with the guide structure 5 is provided on the fixed frame 3, and an adjustable bracket 7 is provided on the fixed frame 3. The adjustable bracket 7 is adjustable and provided with a limit monitoring unit 8 that cooperates with the cutting mechanism 6. The limit monitoring unit 8 is adjusted according to the length of the material to be cut, and is triggered when the front end of the material extends out of the cutting mechanism to reach the set length, thereby controlling the cutting mechanism to cut the conveyed material in a quantitative and fixed length.

[0024] In this embodiment, the fixed frame 3 is a profile frame, the bottom of which is fixed to the ground via anchor bolts. Both the main conveyor belt 1 and the auxiliary conveyor belt 2 include a support frame, each supported on the ground by foot supports. The support frame is equipped with several rollers that collectively support the conveyor belt. The output shaft of one of the rollers is connected to a gearbox, the input of which is in transmission connection with a drive motor fixed to the support frame. This allows the drive motor to rotate the roller, which in turn drives the conveyor belt, achieving material conveyance.

[0025] As a further embodiment, a trough 21 is provided on the secondary conveyor belt 2. The trough 21 has an open top and corresponds to the cutting mechanism 6. In actual use, the material is first conveyed along the main conveyor belt, gathered when passing through the diversion structure, and pressurized by the pressure wheel assembly to prevent jumping. After passing through the cutting mechanism and triggering the limit monitoring unit at the end, the cutting mechanism operates to cut the material to a fixed length. The cut material automatically falls into the trough on the secondary conveyor belt. When the amount of material in the trough reaches the set amount, the secondary conveyor belt operates, driving the trough to move to the unloading area for unloading. This device has a simple structure and high reliability, and is suitable for continuous and non-continuous material quantitative cutting scenarios.

[0026] Example 2, based on Example 1, Figure 2As shown, the pressure wheel assembly 4 includes a roller 41, which is rotatably mounted on a movable frame 42. The movable frame 42 is vertically slidably mounted on the fixed frame 3. A spring 43 is provided between the movable frame 42 and the fixed frame 3. At least one roller 41 is provided. If more than one roller 41 is provided, they are evenly spaced along the movable frame 42. The roller 41 at one end of the incoming material is slightly higher than the other end, allowing the incoming material to enter more easily and be pressed under the roller for forward conveyance. In this embodiment, multiple rollers are provided to more evenly apply pressure to the material.

[0027] In addition, the guide structure 5 includes arcuate guide plates 51 symmetrically fixed to the fixed frame 3. The ends of the arcuate guide plates 51 are connected to parallel guide plates 52, and the movable frame 42 is located between the two parallel guide plates 52 and the two arcuate guide plates 51. When the material enters the guide structure along the incoming direction, it is first gathered by the arcuate guide plates on both sides and conveyed toward the center before entering between the two parallel guide plates. During this process, it first contacts the rollers at the incoming end and then gradually contacts the subsequent rollers, thereby being pressed against the main conveyor belt. Subsequently, as the main conveyor belt continues to convey the material, the rollers roll relative to the material, causing the material to continue to move forward until it passes through the cutting mechanism 6 and triggers the limit monitoring unit 8.

[0028] Example 3, based on Example 2, Figure 3 As shown, the cutting mechanism 6 includes an end plate 61 fixed to the fixed frame 3. The end plate 61 is provided with an opening 62 corresponding to the ends of the two parallel guide plates 52. A cutter 63 is attached to one side of the end plate 61. The cutter 63 is hingedly connected to the end plate 61 and is in transmission connection with the drive unit. In this embodiment, the cutter blade is arc-shaped, and the opening 62 is rectangular or circular.

[0029] Specifically, the driving unit includes a driving motor 64 fixed on the fixing frame 3 . A cam 65 is fixed on the output end of the driving motor 64 . A connecting rod 66 is hinged on the cam 65 . The connecting rod 66 is hinged to the cutter 63 .

[0030] In this embodiment, rotation of the output end of the drive motor synchronously drives the cam. During each rotation of the cam, the connecting rod simultaneously drives the cutter to reciprocate once around its hinged connection with the end plate, thereby severing the material extending through the opening 62 and achieving the slicing function. In scenarios where shredding or slicing is required, the speed of the output end of the drive motor is increased to achieve rapid reciprocating motion of the cutter, while the main conveyor belt synchronously transports the material to achieve slicing.

[0031] In Example 4, based on Example 3, the adjustable bracket 7 includes structural plates 71 symmetrically arranged on both sides of the fixed frame 3. Structural plates 71 are transversely defined with slide grooves 72, which are provided with sliders 73. The position monitoring unit 8 is provided on the sliders 73. In this embodiment, the sliders are threaded with fastening bolts. After the slider is adjusted, the fastening bolts are rotated to lock the slider in position.

[0032] In addition, the position limit monitoring unit 8 includes a beam laser sensor, and a transmitting end and a receiving end of the beam laser sensor are respectively arranged on the sliders 73 on both sides.

[0033] In actual use, when the material is transported by the main conveyor belt and passes through the opening of the end plate, the front end is suspended above the auxiliary conveyor belt. Then, when the front end extends to a set length, the incident laser sensor is triggered, thereby giving a signal to the drive unit. The drive unit drives the cutter to cut the material, and the material falls onto the auxiliary conveyor belt below or into the material trough on the auxiliary conveyor belt.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
