One end of the guide arc groove 43 is connected to the middle of the inner wall of the guide vertical groove 42. The opposite sides of the two groups of fixed plates 41 are rotatably connected with handwheel shafts 44. One end of one group of handwheel shafts 44 passes through the box body 1 and is fixedly connected with a handwheel. The handwheel is convenient for the staff to apply power, thereby facilitating the opening and closing of the box cover 2. The operation is simple and convenient, the structure is simple, the use of driving equipment is reduced, and the production cost of the turnover box is reduced. It is convenient to disassemble and assemble, and convenient to maintain.

[0028] In a further preferred embodiment, Figure 5 As shown, the end of the handwheel shaft 44 away from the handwheel is fixedly connected to a lever 45, and a protrusion is fixedly connected to one side of the lever 45. The lever 45 is rotatably connected to a connecting rod 46 through the protrusion. The end of the connecting rod 46 away from the protrusion is rotatably connected to a synchronization rod 47 slidably connected in the guide vertical groove 42. Both ends of the synchronization rod 47 are rotatably connected to a flip plate 48. The connecting rod 46 is driven to rotate by the lever 45, so that the synchronization rod 47 is raised and the mounting plate is raised at the same time, thereby realizing the rapid opening of the box cover 2.

[0029] Further, such as Figure 5As shown, one side of the flip plate 48 is rotatably connected to a limit pin 49 that is slidably connected to the guide vertical groove 42, and the upper end of one side of the flip plate 48 is fixedly connected to a connecting plate 410, and two groups of fixing bolts are inserted into the lower surface of the connecting plate 410. The limit pin 49 is used to limit the lifting height of the flip plate 48, so that the flip plate 48 is flipped after reaching the highest point, so as to facilitate the opening of the box cover 2, thereby improving the opening efficiency.

[0030] Preferably, Figure 3-5 As shown, the limiting mechanism 6 includes a plurality of telescopic sleeve rods 62 fixedly connected to the lower surface of the box cover 2, and the lower ends of the plurality of telescopic sleeve rods 62 are fixedly connected to a pressing plate 61.

The spring 63 is used to keep the pressing plate 61 away from the box cover 2, so that the pressing plate 61 is pressed tightly on the bottle preform after the box cover 2 is closed, so as to prevent the bottle preform from being damaged by bumps during the transportation of the box body 1, thereby improving the safety of the bottle preform transportation.

[0031] In addition, if Figure 4 As shown, a preform separation grid 7 is fixedly connected to the bottom of the inner cavity of the box body 1, and the preform separation grid 7 is provided with multiple groups of horizontal limiting plates and multiple groups of vertical limiting plates, and the multiple groups of horizontal limiting plates and the multiple groups of vertical limiting plates are alternately arranged vertically.

When the reinforcing inclined plate 53 is separated from the push plate 55, the bottom plate 51 has space for movement in the installation cavity 8, so that the base 3 directly supports the box body 1 to ensure the stability of the box body 1.

[0033] Preferably, Figure 6 As shown, two groups of guide bars 54 are fixedly connected to the upper surface of the mounting cavity 8, and both groups of guide bars 54 are slidably connected to a push plate 55, one side of the push plate 55 is threadedly connected to an adjusting screw 56, and the upper surface of the bottom plate 51 is fixedly connected to a reinforcing inclined plate 53 that contacts the push plate 55, and the guide bars 54 improve the stability of the movement of the push plate 55.

The push plate 55 and the adjusting screw 56 are arranged at an angle. When the adjusting screw 56 rotates, it drives the push plate 55 to move along the guide bar 54, so that the inclined part of the push plate 55 contacts the reinforcing inclined plate 53, and the lower surface of the push plate 55 contacts the upper surface of the reinforcing inclined plate 53. The moving wheel 52 contacts the ground through the bottom hole 9, which facilitates the rapid movement of the box body 1 and reduces the labor of manual handling of the box body 1.

The lever 45 is rotatably connected to the connecting rod 46 through the protrusion, and drives the flip plates 48 at both ends of the synchronous rod 47 to rise along the guide vertical groove 42 through the connecting rod 46. The flip plates 48 drive the box cover 2 to rise through the connecting plate 410. When the limit pin 49 moves to the uppermost end of the guide vertical groove 42, the connecting rod 46 receives the lifting force after the synchronous rod 47 is blocked, so that the synchronous rod 47 is The rod 47 moves along the guide arc groove 43, and the flip plate 48 flips 90 degrees with the limit pin 49 as the axis, so that the box cover 2 is flipped open with the limit pin 49 as the axis and is located on one side of the box body 1, so that the box cover 2 can be quickly opened to facilitate the placement of the bottle preform. The hand wheel shaft 44 is rotated in the reverse direction, and the box cover 2 can be closed on the box body 1 by reverse operation. At the same time, it is supported by the baffle bar to improve the sealing performance of the box cover 2. The operation is simple and convenient, and the efficiency of opening and closing the box cover 2 is improved.
