[0023] The specific embodiments of the present application will be further described in conjunction with the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the present application, and cannot be used to limit the protection scope of the present application.

[0024] Embodiment

[0025] Please refer to Figure 1 A hot-pressing transfer jig for a pulp model comprises a handle 1, the handle 1 is fixedly connected with a panel 2, the panel 2 is detachably provided with a bump 3 through a bolt, and the shape of the bump 3 is adapted to the pulp model. The side of the panel 2 away from the bump 3 is detachably provided with a cover plate 5 through a buckle 4. An elastic net frame 6 is further arranged between the bump 3 and the panel 2, and the elastic net frame is connected with a thread sleeve 8 through a ring groove 7. The elastic net frame 6 can make the bump 3 have a certain amount of floating, so as to avoid insufficient depth when the bump 3 tightly abuts against the pulp model in the concave die of the hot press. The panel 2 and the cover plate 5 are centrally provided with a mounting hole 9, and the elastic net frame 6 is provided with a pull handle 11 through a connecting rod 10 in a direction away from the bump 3 by passing through the mounting hole 9. The bump 3 is arranged in a circumferential array along the elastic net frame 6 through the thread sleeve 8. Pulling the pull handle 11 can make the elastic net frame 6 deform from the pull handle connection to the mounting hole 9, so as to drive the elastic net frame 6 to make the bump 3 tighten in a claw shape, and repeatedly moving the pull handle up and down can make the pulp model adhere more closely to the concave die of the hot press. The elastic net frame 6 only needs to have a deformation ability during the up-and-down floating process, and should not be deformed too much, and is preferably made of steel wire cloth.

[0026] A spherical structure flexible round piece 12 with an outer circumference larger than the elastic net frame 6 is further arranged between the cover plate 5 and the elastic net frame 6, and the flexible round piece 12 is gap-fitted with the elastic net frame 6. The flexible round piece 12 plays a supporting role for the elastic net frame 6, and provides additional supporting force in the process of deforming the elastic net frame 6, so that the operator has a sense of segmentation when touching the flexible round piece 12 during the pulling process. Thus, the operator is reminded to avoid excessive force in rapid pulling and damage the jig.

[0027] A spring 13 is also fixed between the flexible disc 12 and the cover plate 5 through the circular groove 14, the pulling handle 11 passes through the central axis of the spring 13 to position the spring 13, and the two ends of the spring 13 are connected to the flexible disc 12 and the cover plate 5 respectively. The spring 13 allows the flexible disc 12 to float up and down within a certain range and keeps the convex surface structure of the flexible disc facing the direction of the elastic net frame 6, thereby achieving the resetting of the flexible disc 12. A reinforcing sheet 15 is arranged between the connecting rod 10 and the elastic net frame 6 to keep the structure stable.

[0028] Working principle:

[0029] First, make the convex block 3 that fits the paper pulp model, preferably made of silicone or foam plastic, with a shell thickness of about 1 cm. If the thickness is too low, the convex block will be too soft, and if the thickness is too high, it will add unnecessary weight to the convex block. After installing the convex block 3 to the faceplate 2, place the paper pulp model into the concave mold of the hot press, and then insert the convex block 3 into the paper pulp model. When the operator pulls the pulling handle, the connecting rod 10 deforms the elastic net frame 6 from the center to the direction of the mounting hole 9. Due to the spherical structure of the elastic net frame 6, this deformation will cause the convex blocks arranged along the circumference of the elastic net frame to tighten towards the center, forming a technical effect similar to the tightening of a claw, thereby increasing the gripping force on the paper pulp model. Similarly, pressing down the pulling handle 11 will provide a pressure towards the outer periphery of the paper pulp model like opening the palm, and repeated operation will ensure the stability and tightness of the model during the hot pressing process.

[0030] The flexible disc 12 between the cover plate 5 and the elastic net frame 6 has a spherical structure that fits with the elastic net frame 6 with a gap, serving as a support. During the deformation of the elastic net frame 6, the flexible disc 12 provides additional force, allowing the operator to feel the paragraph when pulling the pulling handle 11, which helps the operator to judge whether the appropriate tightening degree has been reached, avoiding excessive force that may damage the paper pulp model.

[0031] The spring 13 is arranged between the flexible disc 12 and the cover plate 5, the pulling handle 11 passes through the central axis of the spring to position the spring 13, and the two ends of the spring are connected to the flexible disc 12 and the cover plate 5 respectively. Its function is to provide a buffer, allowing the flexible disc 12 to float up and down within a certain range while keeping its convex surface structure facing the direction of the elastic net frame. This not only helps to maintain the stability of the paper pulp model during the hot pressing process, but also absorbs part of the impact force generated by the movement of the elastic net frame, protecting the model from damage.

[0032] The reinforcing sheet 15 arranged between the connecting rod 10 and the elastic net frame 6 is used to increase the stability and strength of the structure, preventing the elastic net frame and the connecting rod from deforming or breaking due to excessive force during operation, ensuring the reliability and durability of the entire jig.

[0033] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
