Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, and in particular to a hot pressing and shaping machine for paper product processing and forming. Background Technology

[0002] A paper product hot press setting machine is a piece of equipment used for processing and shaping paper products. Its main function is to process paper products into specific shapes and structures through high temperature and high pressure. During the operation of the hot press setting machine, the combined action of heating and pressure causes the paper material to undergo plastic deformation, thereby achieving the shaping of the paper product.

[0003] Chinese patent CN222251538U discloses a chemical fiber setting machine. Specifically, it discloses a method where a turntable rotates to sequentially heat-press and set multiple cardboard sheets on lower molds. The heat-pressed and set cardboard sheets are then rotated sequentially from an L-shaped plate to the operator's position, facilitating removal and preventing accidental activation of the machine's switches during manual material handling. This avoids potential hazards, and the machine can be set without stopping material handling, improving the efficiency of packaging box setting. While this patent addresses safety by allowing continuous cardboard heating and pressing, it requires manual loading and can only heat-press one cardboard sheet at a time, resulting in low efficiency. Therefore, there is an urgent need for a heat-pressing and setting machine for paper product processing that can not only automatically load materials but also heat-press multiple cardboard sheets simultaneously.

[0032] Please refer to Figures 1 to 4 A hot pressing and setting machine for paper product processing and forming, comprising:

[0033] Base 1;

[0034] The lower hot press plate 2 is provided with four hot press film blocks, and the four hot press modules 21 are arranged in a rectangular array. The upper part of the hot press module 21 is provided with a first heating block 211.

[0036] The feeding mechanism 5 is connected to the base 1. The feeding mechanism 5 includes two feeding devices 51 symmetrically arranged on both sides of the lower hot press plate 2. The feeding device 51 includes a first lead screw guide rail assembly 511, a cylinder 512, a first suction cup 513, a first drive motor 514, and two feeding boxes 515. The two feeding boxes 515 are arranged sequentially on the base 1 along the Y direction. Each feeding box 515 corresponds to a hot press module 21. The first lead screw guide rail assembly 511 is connected to the base 1. The axis of the first lead screw guide rail assembly 511 is vertical. The cylinder 512 is slidably connected to the first lead screw guide rail assembly 511. The first drive motor 514 is drively connected to the first lead screw guide rail assembly 511. The first suction cup 513 is connected to the piston rod of the cylinder 512. The axis of the cylinder 512 is X direction.

[0037] The first drive motor 514 and cylinder 512 drive the first suction cup 513 to switch between the first state and the second state.

[0038] In the first state, the first suction cup 513 is located above the feeding box 515;

[0039] In the second state, the first suction cup 513 is located above the hot pressing module 21.

[0040] In the above embodiments, the cardboard to be thermoformed is placed into the feeding box 515, and then the first drive motor 514 drives the first lead screw guide assembly 511 to rotate, causing the cylinder 512 to move downward, thereby driving the first suction cup 513 to pick up the paper in the feeding box 515. After suction, the cylinder 512 moves upward, and the telescopic rod of the cylinder 512 extends and retracts, so that the first suction cup 513 is located on the thermoforming module 21, and the paper on the first suction cup 513 is placed on the thermoforming module 21. Then, the hydraulic cylinder 31 drives the upper thermoforming plate 4 to move downward, and the paper is thermoformed and shaped by the first heating module and the second heating module. Compared with the prior art, by setting multiple thermoforming modules 21 and the second thermoforming module 21, in conjunction with the feeding mechanism 5, not only can the feeding be automatic, but multiple cardboard pieces can also be thermoformed at the same time.

[0042] In the above embodiments, the second drive motor 12 drives the second lead screw guide assembly 11 to move the lower hot press plate 2, thereby moving the lower hot press plate 2 away from the hot press area, avoiding material handling within the hot press area, and preventing burns.

[0043] As an optional implementation, a material picking device 6 is provided on the upper Y-direction side of the base 1. The material picking device 6 includes a rotary cylinder 61, an electric telescopic rod 62, a connecting plate 63, and a second suction cup 64.

Then the telescopic end of the electric telescopic rod 62 extends and retracts, and the second suction cup 64 is used to hold the cardboard that has been hot-pressed. The rotary cylinder 61 rotates, so that the second suction cup 64 rotates to the unloading area for unloading, thereby realizing automatic unloading and further preventing burns.

[0045] As an optional implementation, the material handling device 6 is provided with a discharge ramp 7 and a conveyor belt 8 on the X-direction side.

The conveying direction of the conveyor belt 8 is Y-direction.

[0046] In the above embodiments, the rotating cylinder 512 rotates to position the second suction cup 64 above the high end of the unloading ramp 7. Then, the second suction cup 64 places the cardboard onto the unloading ramp 7, which slides down the unloading ramp 7 onto the conveyor belt 8, and is then transported by the conveyor belt 8 to the processing area for processing.

[0047] As an optional implementation, the L-shaped fixing base 3 is provided with a limiting guide post 32, the axis of the limiting guide post 32 is vertical, and the upper hot press plate 4 is slidably connected to the limiting guide post 32.
