[0024] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0025] See Figure 1An embodiment of this application provides a press frame return line, which includes a first conveying module 10 and a second conveying module 20. The first conveying module 10 and the second conveying module 20 are arranged side by side.

[0026] Specifically, the first conveying module 10 and the second conveying module 20 are spaced apart along a first direction, and both the first conveying module 10 and the second conveying module 20 extend along a second direction. The first direction intersects the second direction, for example, the first direction is perpendicular to the second direction. X represents the first direction, and Y represents the second direction.

[0027] During operation, the pressure frame is placed on the first conveying module 10 and the second conveying module 20. The first conveying module 10 and the second conveying module 20 operate to realize the return transmission of the pressure frame.

[0028] See Figure 1 The first conveying module 10 includes a first drive wheel and a first drive member 11. At least two first drive wheels are provided, all of which are spaced apart along a second direction, and all are connected by the first drive member 11. The first direction intersects the second direction. Optionally, the first direction is perpendicular to the second direction, and the second direction is represented by Y.

[0029] See Figure 1 The second conveying module 20 includes a second drive wheel and a second drive component 21. There are at least two second drive wheels, all of which are spaced apart along a second direction, and all are connected via the second drive component 21.

[0030] In one embodiment, see 1 and Figure 2 The pressure frame return line also includes a first drive shaft 30, a second drive shaft 40, a drive mechanism 50, and a fastener 60. The first drive shaft 30 is connected to a first drive wheel, and the second drive shaft 40 is connected to a second drive wheel. The fastener 60 is located at the connection point between the first drive shaft 30 and the second drive shaft 40, and is used to lock the first drive shaft 30 and the second drive shaft 40 together. The drive mechanism 50 is driven by one of the first drive shaft 30 and the second drive shaft 40.

[0031] Optionally, the fastener 60 is made of steel. In this way, the fastener 60 has high strength and is not easily deformed.

[0032] During operation, the pressure frame is placed on the first transmission component 11 and the second transmission component 21. The drive mechanism 50 is activated, driving the first transmission shaft 30 and the second transmission shaft 40 to rotate. The first transmission shaft 30 drives the first transmission wheel to rotate, which in turn drives the first transmission component 11 to move. Simultaneously, the second transmission shaft 40 drives the second transmission wheel to rotate, which in turn drives the second transmission component 21 to move, thus achieving the return conveying of the pressure frame. Because fasteners 60 are provided at the connection point of the first transmission shaft 30 and the second transmission shaft 40, the fasteners 60 can lock the first transmission shaft 30 and the second transmission shaft 40, preventing them from shaking or misaligning, reducing wear on the first transmission shaft 30 and the second transmission shaft 40, and preventing breakage at the connection point. At the same time, the fasteners 60 can reinforce the connection point of the first transmission shaft 30 and the second transmission shaft 40, preventing breakage due to stress, improving the utilization rate of the pressure frame return line, and ensuring production efficiency.

[0033] In one embodiment, see Figure 1 The second drive shaft 40 is a bushing, which is nested with the first drive shaft 30. It is understood that the inner diameter of the bushing is larger than the diameter of the first drive shaft 30, and the end of the first drive shaft 30 is movably disposed within the bushing. Thus, when an external force is applied to the first drive shaft 30, the first drive shaft 30 can move axially within the bushing, thereby adjusting the length of the pressure frame return line in the first direction. This allows the pressure frame return line to transport pressure frames of different sizes, improving operational flexibility.

[0034] Furthermore, the side wall of the bushing is provided with a mounting hole, and a limiting member is provided in the mounting hole. The limiting member is used to abut against the outer peripheral surface of the first drive shaft 30. After the length of the return line of the pressure frame is adjusted to the correct position in the first direction, the limiting member abuts against the outer peripheral surface of the first drive shaft 30 to fix the first drive shaft 30 and the second drive shaft 40.

[0035] In one embodiment, see Figure 1 The pressure frame return line also includes a bearing housing 70, which is located in the first conveying module 10 or the second conveying module 20. The bearing housing 70 is provided with bearing holes.

[0036] Further, see Figure 1One of the first drive shaft 30 and the second drive shaft 40 is equipped with a bearing 41, which is disposed within a bearing bore. The first drive shaft 30 or the second drive shaft 40 rotates with the bearing housing 70 via the bearing 41. Under the action of the bearing 41, friction is reduced, energy loss during transmission is reduced, and the transmission efficiency is improved. Simultaneously, the bearing 41 achieves smooth rotation during operation, reducing vibration and noise. The bearing housing 70 provides stable support for the bearing 41 and also bears part of the load, reducing the load on the bearing 41 and preventing premature damage to the bearing 41 under high loads.

[0037] In one embodiment, a fastener 60 is fitted onto the other of the first drive shaft 30 and the second drive shaft 40, and onto the bearing 41. By applying a uniform and appropriate tightening force to the bearing 41 with the fastener 60, the bearing 41 can maintain precise positioning when rotating at high speeds or under complex loads, avoiding abnormal friction and wear caused by loosening of the bearing 41. In addition, it helps to reduce the frequency of downtime maintenance caused by bearing 41 failure in the press frame return line, improves the utilization rate of the press frame return line, and thus ensures production efficiency.

[0038] In one embodiment, see Figure 1 and Figure 2 The fastener 60 includes a first clamp body 61 and a second clamp body 62. The first clamp body 61 and the second clamp body 62 are engaged to form a space for accommodating the first drive shaft 30 and the bearing 41.

[0039] Further, see Figure 3 The first clamp body 61 has a first fixing hole 611, and the second clamp body 62 has a second fixing hole 621. Fixing components are installed in both the first fixing hole 611 and the second fixing hole 621. Optionally, the fixing components are screws or bolts, etc. Thus, the fixing components can lock the first clamp body 61 and the second clamp body 62 together, ensuring that the fastener 60 can lock the first drive shaft 30 and the bearing 41.

[0040] In one embodiment, see Figure 1 and Figure 3 The fastener 60 has a first shaft hole 63, a second shaft hole 64, and a third shaft hole 65, which are sequentially arranged along the axial direction of the fastener 60 and are interconnected. A first drive shaft 30 is disposed within the first shaft hole 63, the diameter of which is adapted to the diameter of the first drive shaft 30. A second drive shaft 40 is disposed within the second shaft hole 64, the diameter of which is adapted to the diameter of the second drive shaft 40. A bearing 41 is disposed within the third shaft hole 65, the diameter of which is adapted to the diameter of the bearing 41.

[0041] Further, see Figure 1 and Figure 3 The diameter of the first shaft hole 63 is smaller than the diameter of the second shaft hole 64, so that a first stepped surface 66 is formed between the first shaft hole 63 and the second shaft hole 64. The first stepped surface 66 is in contact with one end face of the axial direction of the second drive shaft 40. The diameter of the second shaft hole 64 is smaller than the diameter of the third shaft hole 65, so that a second stepped surface 67 is formed between the second shaft hole 64 and the third shaft hole 65. The second stepped surface 67 is in contact with one end face of the axial direction of the bearing 41. In this way, the first stepped surface 66 can position the second drive shaft 40 and prevent the second drive shaft 40 from shifting on the first drive shaft 30. At the same time, the second stepped surface 67 can position the bearing 41 and prevent the bearing 41 from shifting on the second drive shaft 40.

[0042] In one embodiment, in the second direction, both the first conveying module 10 and the second conveying module 20 are provided with at least two.

[0043] The press frame return line also includes a third conveyor module 80. The third conveyor module 80 is located on the side of two adjacent second conveyor modules 20 in the first direction, and the two adjacent second conveyor modules 20 are connected by the third conveyor module 80. A bearing housing 70 is located in the third conveyor module 80. With this configuration, when a problem occurs in one of the first conveyor modules 10 or second conveyor modules 20, maintenance personnel can inspect and repair that individual first conveyor module 10 or second conveyor module 20 without disassembling the entire conveyor module, reducing downtime and improving production efficiency. By setting up the third conveyor module 80, it can serve as an auxiliary conveyor.

[0044] Specifically, the third conveying module 80 includes a third drive wheel and a third drive member 81. At least two third drive wheels are provided, all of which are spaced apart along a second direction, and all are connected via the third drive member 81. One third drive wheel is positioned opposite to a second drive wheel of an adjacent second conveying module 20 and connected to the opposite second drive wheel via a second drive shaft 40. The other third drive wheel is positioned opposite to a second drive wheel of another adjacent second conveying module 20 and connected to the opposite second drive wheel via a connecting shaft.

[0045] In one embodiment, see Figure 1 In the first direction, the second conveying module 20 is provided on both opposite sides of the first conveying module 10. Optionally, two second conveying modules 20 are provided in the first direction. In this way, the length of the frame return line in the first direction can be increased to better convey large-sized frames.
