Problems solved by technology

As a result, even if the clamping force of the hot pressing mold is increased to a great extent, some parts of the product have been pressed black and some parts are still not "light", and the surface quality of the product has no obvious change; and it is even more impressive. The troublesome thing is: (1) Adjusting the gap of the mold according to the surface effect of the product is very blind, and it is often difficult to achieve the goal; (2) The cost of adjusting the gap of the mold is very high. Stop the machine and remove the mold to reprocess the mold. It takes a long time to cool down the mold at about 200°C to normal temperature. The heat loss is large, the time is too long, and the efficiency is low.
[0012] Therefore, it is necessary to invent a method to solve the problem that the hot pressing mold is easy to crack the product and it is difficult to calender the surface of the product when the hot pressing is dried and shaped.

Embodiment 1

[0066] Such as figure 1 As shown, in this embodiment, the pulp molding equipment for transferring the wet billet by the tumbler includes a machine frame, a suction filter forming device, a hot press setting device, a first wet billet transfer device, a second wet billet transfer device, a control system, and the like. In the middle of the lower frame 1a, a suction filter forming device 2 is arranged, above the suction filter forming device 2, a first wet base transfer device 7 is arranged, and a hot press setting device 3 is respectively provided on the left and right sides of the frame, respectively. It is a left heat press setting device 3L and a right heat press setting device 3R.

[0067] Such as figure 1 As shown, the frame 1 is composed of a lower frame 1a, an upper frame 1b, and a tie rod 1c, and the tie rod 1c fixes the lower frame 1a and the upper frame 1b together.

[0068] Suction filter forming device 2 contains suction filter forming mold 2a, suction filter form...

Embodiment 2

[0103] This embodiment is a simplification of Embodiment 1, such as Figure 6 As shown, the pulp molding equipment of the present embodiment that transfers the wet billet with the tumbler only contains one thermocompression setting device. In this embodiment, the pulp molding equipment for transferring the wet billet by the tumbler includes a frame 1, a suction filter molding device 2, a hot press setting device 3, a second wet billet transfer device 5, a first wet billet transfer device 7, a control system etc.

[0104] Because there is only one heat-press setting device, there is no distinction between the left heat-press setting device and the right heat-press setting device. The implementation principle is the same as that of Embodiment 1.

Embodiment 3

[0106] Such as Figure 7 , Figure 8 As shown, the pulp molding equipment for transferring wet billets by a tumbler includes a machine frame, a suction filter forming device, a hot press setting device, a first wet billet transfer device, a second wet billet transfer device, a control system, and the like.

[0107] Such as Figure 7 , Figure 8 As shown, on the left side of the pulp molding equipment where the tumbler transfers the wet billet, there is a receiving table 10 for placing the dried and shaped product 11 .

[0108] On the lower side of the upper frame from the left end to the right end, fix 2 (or 2 groups) left and right translation rails 8, and the left and right translation rails 8 span the top of the material receiving table 10, the top of the hot pressing lower die, and the top of the first wet billet transfer device 7 .

[0109] The suction filtration molding device and the first wet billet transfer device are the same as those in Embodiment 1 and Embodime...

Abstract

The invention relates to a method and a device for manufacturing a plant fiber product comprising paper pulp in a molding forming mode. According to the method and the device, the two surfaces of a plant fiber molded product have better effects. According to the technical scheme, the manufacturing method of the paper pulp molded product is carried out according to the following steps that after being manufactured in a suction filtration forming mold, a wet blank is transferred to a hot-pressing shaping device, and is subjected to hot-pressing, drying and shaping to manufacture the paper pulp molded product. The method is characterized in that in a transferring process, a first wet blank transferring device and a second wet blank transferring device are adopted to transfer a wet blank from a suction filtration forming mold to a hot-pressing shaping device, wherein the first wet blank transferring device is used for extracting the wet blank from the suction filtration forming mold and transferring the wet blank to the second wet blank transferring device, then the second wet blank transferring device is used for transferring the wet blank to the hot-pressing shaping device, the number of the hot-pressing shaping devices can be one or more, and the multiple hot-pressing shaping devices comprise a left hot-pressing shaping device and a right hot-pressing shaping device.

Description
