[0033] Please refer to the attached Figure 1 - attached Figure 3 Referring to the attached drawings, the first aspect of this embodiment relates to an adjustment mechanism, which includes a frame body 1, a driving member 2, a limiting member 3 and a bidirectional lead screw 5. Among them, the driving member 2 is arranged on the frame body 1; two limiting members 3 are arranged oppositely, and a channel 4 for the material to pass through is formed between the two limiting members 3; the bidirectional lead screw 5 passes through the two limiting members 3 in sequence and is threadedly connected with the limiting members 3. One end of the bidirectional lead screw 5 is in transmission connection with the driving member 2, and the driving member 2 is used to drive the bidirectional lead screw 5 to rotate, so that the two limiting members 3 approach or move away from each other to adjust the width of the channel 4.

[0034] In this embodiment, this adjustment mechanism is located above the conveyor line. The conveyor line is used to convey materials, and the adjustment mechanism is used to adjust the materials into an accurate placement state and an accurate position relative to the conveyor line. Among them, the frame body 1 is used to provide positioning and support for other components of this mechanism. The driving member 2 can adopt a rotary motor. The driving member 2 drives the bidirectional lead screw 5 to rotate, and at the same time enables the two limiting members 3 that are threadedly engaged with the bidirectional lead screw 5 to approach or move away from each other in the horizontal direction. A channel 4 for limiting the materials is formed between the two limiting members 3. By adjusting the distance between the two limiting members 3 to adjust the width of the channel 4, so as to adapt to materials with different width dimensions to pass through this adjustment mechanism, in order to achieve the purpose of adjusting the placement state and position of the materials. Based on the ability to adapt to the conveying of materials with different sizes, this adjustment mechanism can further realize rapid automatic adjustment, effectively improving the efficiency of material conveying and production.

[0035] Optionally, the frame 1 includes two oppositely arranged vertical plates 11 , the limiting member 3 is arranged between the two vertical plates 11 , and the driving member 2 is detachably connected to a side wall of one of the vertical plates 11 away from the limiting member 3 .

[0036] In this embodiment, the vertical plate 11 is a metal plate, fixed to both sides of the conveyor line along the conveying direction. The stopper 3 is also a plate-shaped member. The bidirectional screw 5 first passes through the vertical plate 11 on one side, then passes through the two stoppers 3 in sequence, and finally exits the vertical plate 11 on the other side. The drive member 2 is fixed to the drive seat 22, which is fixed to the outer wall of the vertical plate 11 on one side via threaded fasteners. The drive member 2 is in transmission connection with the end of the bidirectional screw 5 extending from the vertical plate 11. The entire frame 1 is an open structure, which allows users to easily maintain the entire mechanism and observe the status of material conveying in real time. The overall structure is simple.

[0037] Optionally, the end of the limiting member 3 extends in a direction away from the other limiting member 3 .

[0038] In this embodiment, the limiting member 3 is a plate-shaped member that is parallel to the vertical plate 11 and is upright. The starting and ending ends of the channel 4 on the limiting member 3 extend outward to form a trumpet hole shape to facilitate the smooth entry and exit of materials into and out of the channel 4.

[0039] Optionally, the adjustment mechanism further includes a guide shaft 7 , one end of which is fixed on the limit member 3 , and the other end of which is slidably connected to the frame 1 via a linear bearing 71 .

[0040] In this embodiment, one end of multiple guide shafts 7 is directly fixed to the limiter 3, and the other end is slidably connected to the frame 1 through a linear bearing 71. The guide shafts 7 further provide a certain support force for the limiter 3 to ensure the stability of the limiter 3. The use of linear bearings 71 can provide sufficient support for the guide shafts 7 and ensure a stable sliding state. The standard structure of the linear bearings 71 can be directly selected, ensuring the interchangeability and versatility of the mechanism. The guiding effect of the guide shafts 7 on the two limiters 3 can ensure the accurate and stable relative movement of the two limiters 3.

[0041] Optionally, a nut 31 is fixed on the limiting member 3 , and the bidirectional screw rod 5 is threadedly connected to the nut 31 .

[0042] In the present embodiment, a positioning hole is provided on the limit member 3, and a stepped nut 31 is fixed inside the positioning hole. The internal thread of the nut 31 is screwed together with the external thread of the bidirectional screw rod 5 to realize transmission. Of course, the internal thread that matches the external thread of the bidirectional screw rod 5 can also be directly processed inside the positioning hole, so that the bidirectional screw rod 5 directly drives the limit member 3 to reduce the number of parts and reduce the assembly links. In the present embodiment, the nut 31 is matched with the bidirectional screw rod 5, which can transfer the transmission wear between the nut 31 and the bidirectional screw rod 5 to the nut 31, thereby protecting the limit member 3. When the nut 31 reaches the wear limit, the nut 31 can be directly replaced to avoid directly replacing the limit member 3, which reduces the cost to a certain extent. Those skilled in the art can comprehensively consider whether to adopt the nut 31 based on the cost.

[0043] Optionally, two groups of bidirectional screw rods 5 are provided, wherein one group of bidirectional screw rods 5 is transmission-connected to the other group of bidirectional screw rods 5 via a transmission assembly 6 , wherein the driving member 2 is transmission-connected to one group of bidirectional screw rods 5 .

[0044] In this embodiment, two groups of bidirectional screw rods 5 are arranged at intervals in the entire horizontal plane and perpendicular to the conveying direction to improve the stability of the movement of the limit member 3. By using the transmission assembly 6 to connect the two groups of bidirectional screw rods 5, the two groups of bidirectional screw rods 5 can be ensured to rotate synchronously, thereby avoiding damage to the limit member 3 due to the asynchrony of the two groups of bidirectional screw rods 5; in addition, the use of the transmission assembly 6 can not only ensure the synchronization of the movement of the two groups of bidirectional screw rods 5, but also further avoid the addition of a driving member 2, thereby making the structure of the entire mechanism more compact, reducing the number of driving sources, and reducing the cost of the adjustment mechanism.

[0045] Optionally, the driving member 2 is connected to one set of bidirectional screw rods 5 via a coupling 21 .

[0046] In this embodiment, the rotating motor of the driver 2 is connected to one set of bidirectional screws 5 via the motor output shaft, with a coupling 21 interposed between the two. Coupling 21 facilitates power and torque transmission while also compensating for installation errors between the motor output shaft and the connection between the bidirectional screws 5, ensuring transmission stability. Furthermore, coupling 21 provides an automatic disconnect mechanism in the event of an overload, enhancing the stability and safety of the entire mechanism.

[0047] Optionally, the transmission assembly 6 includes two sets of synchronous pulleys 61 respectively sleeved on the ends of the two sets of bidirectional screw rods 5 and a synchronous belt 62 meshing with the two sets of synchronous pulleys 61 for transmission.

[0048] In this embodiment, a synchronous pulley 61 is provided at the end of the bidirectional screw rod 5, and the two sets of synchronous pulleys 61 are engaged and transmitted through a synchronous belt 62. The use of engaged transmission can ensure that the speed and angle of rotation of the two sets of bidirectional screw rods 5 are consistent, thereby realizing the synchronous rotation of the two sets of bidirectional screw rods 5.

[0049] Further, the transmission assembly 6 further includes a tension pulley 63, a connecting shaft 64, an adjusting seat 65 and a locking bolt 66. The tension pulley 63 is rotatably connected to one end of the connecting shaft 64, and the other end of the connecting shaft 64 is fixed on the adjusting seat 65. The adjusting seat 65 is connected to the frame 1 and can adjust its position relative to the frame 1 in the vertical direction. The locking bolt 66 can pass through the adjusting seat 65 and be screwed with the frame 1 to fix the adjusting seat 65.

[0050] In this embodiment, the tension pulley 63 is also a gear meshing with the synchronous belt 62. The tension pulley 63 is arranged between two synchronous belt pulleys 61. Since the synchronous belt 62 has a certain ductility, the tension pulley 63 is used to press the synchronous belt 62 to make it taut. Further, a strip-shaped guide hole 111 extending in the vertical direction is provided on the vertical plate 11. The tension pulley 63 is sleeved on the connecting shaft 64, and the connecting shaft 64 is arranged in the guide hole 111. By moving the connecting shaft 64 in the guide hole 111, the position of the tension pulley 63 can be adjusted in the vertical direction to adapt to tensioning the synchronous belt 62 at different positions. An adjusting seat 65 is arranged on the inner side of the vertical plate 11. Strip-shaped sliding holes 651 are provided along the vertical direction on the opposite sides of the adjusting seat 65. The locking bolt 66 is arranged in the sliding holes 651. The end of the connecting shaft 64 away from the tension pulley 63 is screwed and fixed on the adjusting seat 65. By loosening the locking bolt 66 and moving the adjusting seat 65 along the vertical direction, the connecting shaft 64 and the tension pulley 63 can be driven to adjust their positions in the vertical direction. When the tensioning and fixing position is determined, the locking bolt 66 can be directly tightened completely to fix the tension pulley 63. On the inner side of the vertical plate 11, a fixing block 68 is also fixed by a threaded fastener. The fixing block 68 is located above the adjusting seat 65. An adjusting screw 67 is arranged through the fixing block 68 in the vertical direction. The end of the adjusting screw 67 is used to press the adjusting seat 65 in the vertical direction to assist the adjusting seat 65 to move downward.

[0051] The second aspect of this embodiment also relates to a conveying device, which includes a conveying line and the above-mentioned adjusting mechanism. Materials are placed and conveyed on the conveying line so that the materials can adjust their placement states and accurate positions relative to the conveying line through the channel 4 of the adjusting mechanism.
