DETAILED DESCRIPTION

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-6 As shown, a stacking mechanism of a sheet thermoforming machine comprises a main board 1, and a plurality of rotating shafts 2 are rotatably installed on the side where two main boards 1 are close to each other. The plurality of rotating shafts 2 are horizontally distributed along the surface of the main board 1, and one of the rotating shafts 2 is externally connected to a power source. A conveyor belt 3 is sleeved on the outer surface of the rotating shaft 2. The rotating shaft 2 drives the conveyor belt 3 to transport materials. The rotating shafts 2 between the conveyor belts 3 play a supporting role. A separation plate 4 is arranged between the two main boards 1 corresponding to the conveyor belt 3. The separation plate 4 separates the materials into two parts. Transmission shafts 5 are arranged on both sides of the separation plate 4 and on the side where the two main boards 1 are close to each other. A conveyor belt 6 is sleeved on the outer surface of the conveyor shaft. A connecting rod 6 is arranged between the conveyor belt 6 and the conveyor belt 3. The connecting plate is fixedly connected to the separation plate 4, and the rotation speeds of the two transmission shafts 5 are different, so that the moving speeds of the materials on the two conveyor belts 6 are different. When the materials pass through the connecting plate, since the connecting plate has no transmission, the initial speed of the materials when entering the conveyor belt 6 is 0. The staff can adjust the rotation speeds of the two transmission shafts 5 according to the size of the materials. The two main boards 1 corresponding to the conveyor belt 6 are fixedly installed with sliding devices 7 on the sides close to each other. The sliding device 7 adjusts the position of the materials on the conveyor belt 6. The side of the conveyor belt 6 away from the conveyor belt 3 is provided with a collecting device 8. The collecting device 8 merges the materials on both sides of the separation plate 4 into one, and at the same time enables the materials to be automatically collected and discharged;

[0024] The collecting device 8 includes a first main body 9, and a through groove 10 is opened inside the first main body 9. After the materials enter the through groove 10, the materials are stacked on each other. Two movable grooves 11 are opened on the inner wall of the through groove 10. The two movable grooves 11 are symmetrically distributed about the center line of the through groove 10. A guide rod 12 is fixedly installed on the inner wall of the movable groove 11. The outer surfaces of the two guide rods 12 are both sleeved with movable plates 13. A discharge groove 14 is opened through the inner wall of the through groove 10 corresponding to the movable plate 13. When the stacked materials reach a certain amount, the materials leave the equipment through the discharge groove 14.

[0025] like Figure 4 As shown, the sliding device 7 includes a second main body 15, a rotating groove 16 is opened inside the second main body 15, and a plurality of rotating rods 17 are rotatably installed on the inner wall of the rotating groove 16. The plurality of rotating rods 17 are linearly distributed along the inner wall of the rotating groove 16, and rollers 18 are fixedly installed on the outer surfaces of the plurality of rotating rods 17. The material on the conveyor belt 6 hits the roller 18, and the position of the material is changed at the same time.

[0026] like Figure 5 As shown, a slide groove 19 is provided on one side of the two movable plates 13 away from the guide rod 12, a placement plate 20 is provided inside the slide groove 19, and a replacement device 21 is provided inside the first main body 9 corresponding to the placement plate 20. The stacked materials fall into the placement plate 20 through the through groove 10. When the number of stacks reaches a certain number, the replacement device 21 can replace the placement plate 20 and allow the material to leave the equipment at the same time.

[0027] like Figure 6 As shown, the replacement device 21 includes a third main body 22, and a placement groove 23 is opened inside the third main body 22. A push rod 24 is fixedly installed on the inner wall of the placement groove 23 corresponding to the placement plate 20. The push rod 24 is externally connected to a power source. A feed groove 25 is opened on the top of the placement groove 23 corresponding to the push rod 24. The idle placement plate 20 is placed in the placement groove 23 through the feed groove 25, and the push rod 24 pushes the idle placement plate 20 to replace the placement plate 20 loaded with materials.

[0028] like Figure 6 As shown, a spring 26 is sleeved on the outer surface of the guide rod 12, and the two ends of the spring 26 are fixedly connected to the bottom surface of the moving plate 13 and the bottom of the inner wall of the moving groove 11 respectively. A certain amount of stacked materials pushes the placement plate 20 and then squeezes the spring 26, reducing the height of the material entering the placement plate 20 and reducing the probability of material damage.

[0029] like Figure 1-2 As shown, a motor 27 is provided on the outer side of the main board 1 corresponding to the transmission shaft. The transmission shaft passes through the main board 1 and is fixedly connected to the output end of the motor 27 . The motor 27 serves as a power source for the transmission shaft 5 .

[0030] like Figure 4As shown, the material of the roller 18 is rubber and polyurethane. The roller 18 made of rubber and the roller 18 made of polyurethane have certain elasticity and can quickly return to their original state when impacted, thereby reducing damage to the material caused by the impact.

[0031] Working principle: the formed material enters the surface of the conveyor belt 3 and passes through the separation plate 4, and then passes through the connecting plate. Since the connecting plate has no transmission, the initial velocity of the material is 0 when it enters the conveyor belt 6. The staff can adjust the rotation speed of the two transmission shafts 5 according to the size of the material, so that the material enters the through groove 10 in turn, and adjusts it. The material is stacked in the through groove 10 and enters the surface of the placement plate 20. The stacked material squeezes the placement plate 20 and then squeezes the spring 26. When the stacked material reaches a certain amount, the push rod 24 pushes the idle placement plate 20 to replace the placement plate 20 loaded with material, so that the material leaves the equipment.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
