[0002] At present, large plastic airtight packaging boxes manufactured by rotational molding are widely used in the market. When the large plastic airtight packaging boxes are taken out under high temperature conditions just after rotational molding and are exposed to the lower temperature outside to produce a rapid cooling process, if the large plastic airtight packaging boxes are not cooled and shaped, it will cause partial collapse and deformation of the product, thereby causing the entire product to be scrapped due to errors in production dimensions; however, there is currently no machine dedicated to cooling and shaping large plastic airtight packaging boxes. The usual practice is to support the inner and outer sides of the large plastic airtight packaging box with multiple wooden frame templates. This cooling and shaping method is quite troublesome and laborious, and the process of disassembling and assembling the wooden frame templates is also very complicated, and the work efficiency is extremely low. In particular, the actual effect of this cooling and shaping method is not reliable, and it is still easy to have a defective rate of products. Utility Model Content

[0028] A cooling and shaping machine for large plastic airtight packaging boxes relates to a cooling and shaping machine specially used for cooling and shaping large rotationally molded products. Its structure includes a frame 1, which is a T-shaped frame composed of a front longitudinal frame 11 and a transverse frame 12 perpendicular to the longitudinal frame. A plurality of supporting legs are arranged at the bottom of the frame 1 for lifting support.

[0029] The longitudinal frame 11 and the transverse frame 12 are both rectangular frame structures formed by welding a rectangular frame at the top, a rectangular frame at the bottom, and four vertical poles at the four corners. An entrance 111 is provided at the front of the longitudinal frame 11, and after a supporting core frame 7 is set in the large plastic airtight packaging box 2, it can be loaded into and placed in the longitudinal frame through the entrance 111, and a bottom plate 15 supporting the large plastic airtight packaging box 2 and the supporting core frame 7 is provided in the longitudinal frame 11, and outlets 121 are respectively provided on both sides of the transverse frame 12.

[0030] The supporting core frame 7 is composed of a rectangular core frame 71, a front plate 72 fixed to the front side of the rectangular core frame, and side plates 73 respectively installed on both sides of the rectangular core frame. The front ends of the side plates on both sides are fixed on the front plate 72 and can lift the bottom surface of the rectangular core frame 71. The front plate 72 is provided with a transport port 721 to facilitate a forklift to reach in and transport the supporting core frame 7. For example, the supporting core frame 7 with a large plastic airtight packaging box 2 can be loaded through the entrance 111 and placed in the longitudinal frame 11 by a forklift, or the supporting core frame 7 without the large plastic airtight packaging box 2 can be taken out of the longitudinal frame 11 through the entrance 111.

[0031] Gaps are reserved between the two side surfaces of the rectangular core frame 71 and the two side panels 73, and an inflation port 74 is provided on the supporting core frame 7. When the box opening of the large plastic airtight packaging box 2 faces forward and is inserted into the rectangular core frame 71 of the supporting core frame 7 from back to front, the inflation port 74 is filled with gas to fill the space between the supporting core frame 7 and the large plastic airtight packaging box 2, specifically, between the rectangular core frame 71 and the large plastic airtight packaging box 2, thereby assisting the cooling and shaping of the large plastic airtight packaging box 2 or assisting in pushing the large plastic airtight packaging box 2 to move away from the supporting core frame 7.

[0032] The top of the frame adjacent to the entrance 111, that is, the top of the longitudinal frame 11, is provided with a top clamping plate 3 that moves up and down along the Z direction, and the two sides of the frame adjacent to the entrance 111, that is, the two sides of the longitudinal frame 11, are respectively provided with side clamping plates 4 that move back and forth along the Y direction, and the rear part of the frame facing the entrance 111, that is, the horizontal frame 12, is provided with a rear clamping plate 5 that moves back and forth along the X direction.

[0033] Among them, the Z-direction lifting and lowering movement of the top clamping plate 3 is achieved by providing a top bracket 31 and a top screw rod 32 threadedly rotatably installed on the top bracket at the top of the frame 1. The inner end of the top screw rod is connected to the top clamping plate 3, and the outer end of the top screw rod 32 is driven to rotate, so that the rotation of the top screw rod 32 can be converted into driving the top clamping plate 3 to lift and lower in the Z direction in the top bracket 31. The outer end drive of the top screw rod 32 can be installed with a handwheel 14 as shown in this embodiment, and rotated by manual drive of the handwheel, or an electric drive mechanism can be installed.

[0034] The Y-direction reciprocating movement of the side clamping plates 4 on both sides of the longitudinal frame is achieved by providing side brackets 41 on both sides of the frame 1, each side bracket being provided with a side screw rod 42 which is rotatably installed with a thread, the inner end of the side screw rod being connected to the side clamping plate 4, the outer end of the side screw rod 42 being driven to rotate, and then the rotation of the side screw rod 42 is converted into driving the side clamping plate 4 to reciprocate in the Y direction in the side bracket 41, and the outer end of the side screw rod 42 can also be installed with a hand wheel 14 for manual drive or an electric drive mechanism.

[0035] In addition, four top guide rods 33 are provided on the top clamping plate 3, and the four top guide rods can move vertically through the guide sleeve 13 on the top bracket 31, so as to jointly guide the vertical lifting movement of the top clamping plate 3 in the Z direction, and four side guide rods 43 are also provided on the side clamping plate 4, and the four side guide rods can move horizontally through the guide sleeve 13 on the side bracket 41, so as to jointly guide the horizontal reciprocating movement of the side clamping plate 4 in the Y direction.

[0036] The reciprocating movement of the rear clamping plate 5 in the X direction is that the rear clamping plate is suspended on the top of the cross frame 12 through the inverted pulley set 51 at the top, so that the rear clamping plate is reciprocatingly arranged in the cross frame 12 along the X direction.

[0037] In this way, the top clamping plate 3, the side clamping plates 4 on both sides and the rear clamping plate 5 move together and press the top surface, both side surfaces and the back of the large plastic airtight packaging box 2 from the outside, and then cooperate with the internal pressing of the supporting core frame 7 to form the cooling and shaping of the large plastic airtight packaging box 2. After the top clamping plate 3, the side clamping plates 4 on both sides and the rear clamping plate 5 move together to separate from the top surface, both side surfaces and the back of the large plastic airtight packaging box 2, the large plastic airtight packaging box 2 can be moved away from the supporting core frame 7 and can be taken out from the outlet 121 at the rear of the frame 1.

[0038] At the same time, a plurality of movable bolt groups 6 are also provided at the rear of the longitudinal frame 11. When the rear clamp plate 5 moves along the X direction and presses against the back of the large plastic airtight packaging box 2, the plurality of movable bolt groups 6 can simultaneously connect the rear clamp plate 5 to form a temporary fixation, thereby improving the reliability of cooling and shaping.

[0039] Obviously, this special cooling and shaping machine can better avoid the trouble of using multiple wooden frame templates to support cooling and shaping in the traditional way, and has the advantages of simple cooling and shaping process, labor saving, high work efficiency, and reliable shaping effect.

[0040] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
