[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] like Figures 1 to 6As shown, an automatic flipping and track-changing device of the present invention includes: a fixed seat 300, a flip plate 400, a rotating shaft 600, and a lifting device 700. A driving device 100 is installed on one side of the fixed seat 300, and a flip shaft 430 is fixedly connected to the flip plate 400. The flip shaft 430 passes through the fixed seat 300 and is transmission-connected with the driving device 100. The flip plate 400 is connected to a connecting plate 530. The rotating shaft 600 is fixedly connected to the connecting plate 530. A forming template 610 is fixedly connected to the rotating shaft 600. The end of the rotating shaft 600 is sleeved with a first bearing 620. The lifting device 700 is fixedly connected to the rotating shaft 600 to drive the rotating shaft 600 to perform lifting and lowering movements.

[0028] The present invention can avoid jamming during movement, reduce the risk of bearing damage, and increase the service life of the flipping and shunting device. It is also convenient for maintenance, runs smoothly, and is easy to debug. After rotating to absorb slurry, molding processing can be carried out, thereby improving the efficiency of molding processing. When molding processing is required, the mold to be used is installed on the molding template 610. At this time, the molding template 610 is in a face-up state. The driving device 100 drives the flip plate 400 to flip through the transmission connection with the flip shaft 430. The rotation of the flip plate 400 drives the connecting plate 530 to rotate as well, thereby driving the rotating shaft 600 to rotate. After rotating 180 degrees, the molding template 610 is in a face-down state. The lifting device 700 drives the rotating shaft 600 to move downward, driving the molding template 610 to move downward, so that the mold enters the slurry pool of the pulp molding machine for slurry absorption. After the slurry absorption process is completed, the lifting device 700 drives the rotating shaft 600 to move upward, driving the molding template 610 to move upward, so that the mold after slurry absorption is completed leaves the slurry pool. When the axis of the rotating shaft 600 moves upward, the rotating shaft 600 moves downward. When the turning shaft 430 is at the same horizontal position as the axis of the turning shaft 430, the driving device 100 drives the turning plate 400 to rotate 180 degrees, driving the connecting plate 530 and the rotating shaft 600 to rotate and reset. At this time, the forming template 610 returns to the upward state, and the lifting device 700 drives the rotating shaft 600 to continue to rise, driving the forming template 610 and the mold to move upward, and the mold and the forming upper mold of the pulp molding machine perform molding processing on the product. The turning and merging device uses the driving device 100 to drive the turning shaft 430 to rotate, thereby avoiding the occurrence of jamming, reducing the risk of bearing damage, and ensuring smooth operation. The turning shaft 430 drives the turning plate 400 and the rotating shaft 600 to rotate, so that the forming template 610 fixed on the rotating shaft 600 rotates, allowing the mold to absorb slurry and prepare for molding processing. The lifting device 700 drives the rotating shaft 600 to perform lifting and lowering motion to realize the lifting function. The turning and merging device enables the forming template 610 to have rotation and lifting functions, which is convenient for molding processing, improves molding processing efficiency, facilitates maintenance, runs smoothly, and is easy to debug.

[0029] Furthermore, the lifting device 700 includes a first track plate 410 and a second track plate 420. The first track plate 410 is fixedly connected to both sides of the flip plate 400. The second track plate 420 is arranged along the vertical direction of the first track plate 410, respectively arranged above and below the first track plate 410. The second track plate 420 is fixedly connected to the fixing seat 300. The first track plate 410 and the second track plate 420 form a vertical guide groove 440. A sliding component 500 is slidably installed between the first track plates 410. The sliding component 500 is fixedly connected to the connecting plate 530. When the lifting device 700 drives the rotating shaft 6 00 moves downward, driving the forming template 610 to move downward, so that the mold enters the slurry pool of the pulp molding machine to absorb slurry, the rotating shaft 600 drives the connecting plate 530 to move, thereby driving the sliding component 500 to move downward, and the sliding component 500 moves along the vertical guide groove 440 formed by the first track plate 410 and the second track plate 420, sliding from the first track plate 410 to the second track plate 420, guiding the lifting and lowering of the rotating shaft 600, when the lifting device 700 drives the rotating shaft 600 to move upward for reset, the sliding component 500 slides from the second track plate 420 back to the first track plate 410.

[0030] like Figures 2 to 6 As shown, further, the lifting device 700 includes a frame 710, and a guide column 720 is arranged on the frame 710 in a vertical direction. The direction of the guide column 720 is parallel to the direction of the first track plate 410. A slider 730 is sleeved on the guide column 720, and the slider 730 is connected to the rotating shaft 600. The slider 730 slides along the guide column 720, and the direction of the guide column 720 is parallel to the direction of the guide groove 440, so that the sliding component 500 can move along the guide groove 440, ensuring that the lifting direction of the rotating shaft 600 is consistent with the direction of the guide groove 440, thereby improving the processing accuracy.

[0031] like Figure 1 As shown, in order to pull the rotating shaft 600 to move up and down, a sprocket 740 is installed on the frame 710, and a chain 750 is sleeved on the sprocket 740. The chain 750 is fixedly connected to the slider 730 to drive the slider 730 to move up and down along the direction of the guide column 720. The slider 730 is connected to the rotating shaft 600, and the chain 750 pulls the slider 730 to move along the guide column 720, thereby driving the rotating shaft 600 to move up and down.

[0032] like Figures 2-4 As shown, further, the driving device 100 includes a servo motor, and the flip shaft 430 is transmission-connected to the servo motor. The servo motor has high precision, stable operation, and strong adaptability, so that the flip shaft 430 rotates smoothly.

[0033] In order to reduce the rotation speed and increase the torque, a reducer 200 is installed on the fixed seat 300, the servo motor is connected to the reducer 200, and the flip shaft 430 is inserted into the reducer 200 and is connected to the servo motor through the reducer 200. The high speed and low torque output by the servo motor are transmitted through the reducer 200 to output low speed and high torque to the flip shaft 430, thereby driving the flip plate 400 to rotate.

[0034] In order to reduce the friction coefficient of the flip shaft 430 during rotation, a second bearing 310 is installed on the fixed seat 300, and the flip shaft 430 passes through the second bearing 310 and is inserted into the reducer 200. The second bearing 310 reduces the friction coefficient of the flip shaft 430 during rotation, reduces the friction force, and thus reduces the energy loss during the rotation of the flip shaft 430.

[0035] like Figure 4 As shown, further, the sliding component 500 is a third bearing 510, and a fixed shaft 520 is inserted on the third bearing 510. The fixed shaft 520 is fixedly connected to the third bearing 510, and the fixed shaft 520 is fixedly connected to the connecting plate 530. Since the third bearing 510 is fixedly connected to the fixed shaft 520 and no relative rotation occurs, when the flip plate 400 rotates, the connecting plate 530 can be driven to rotate, thereby rotating the rotating shaft 600.

[0036] like Figures 2-4 As shown, in order to provide support for the rotating shaft 600, the rotating shaft 600 is sleeved with a fourth bearing 630 between the connecting plate 530 and the forming template 610. The rotating shaft 600 and the fourth bearing 630 are rotatably connected. The fourth bearing 630 provides support for the rotating shaft 600 and reduces the friction coefficient when the rotating shaft 600 rotates.

[0037] In order to improve the accuracy, a sensor (not shown in the figure) for detecting the axis position of the rotating shaft 600 is installed on the fixed seat 300. The sensor detects the position of the axis center of the rotating shaft 600. The rotating shaft 600 will only rotate when the axis center of the rotating shaft 600 and the axis center of the flip axis 430 are at the same horizontal position, thereby reducing the error of the rotation position and improving the accuracy of the machine during operation.

[0038] The embodiment is described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiment. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the present invention.
