Description

Technical Field

[0001] The utility model belongs to the field of paper product equipment, and particularly relates to a down-pressing wet press. Background Art

[0002] In the process of paper product processing, preliminary forming by pulp fishing is required first, and then wet pressing is carried out, and a wet press is needed for wet pressing. At present, the more commonly used one is the down-pressing wet press. Generally, the down-pressing wet press includes an upper die assembly and a lower die assembly. The lower die assembly is fixedly arranged, and the upper die assembly rises and falls to complete the wet pressing work. Since the lower die assembly is fixedly arranged, the operator needs to bend down to enter between the upper die assembly and the lower die assembly to transfer the wet-pressed product, which is extremely inconvenient for work and has potential safety hazards. To overcome the above defects, a wet press appears in the market. A movable die is arranged on the lower die assembly, and the die moves horizontally to take out the product. The operator can transfer the product without bending down and has high safety. However, since the die is movably arranged, friction inevitably occurs between the die and the substrate connected thereto, and clearance fit is required between the two. Therefore, the die needs to be set with a large tolerance, which affects the accuracy of the die, and the moving friction also accelerates the wear of the equipment. Therefore, new problems are brought after solving the convenience and safety. At present, the wet press urgently needs to solve the above problems. Summary of the Utility Model

[0003] To overcome the deficiencies and existing problems of the prior art, the utility model provides a down-pressing wet press. The lower die assembly can move integrally, which is convenient for the operator to transfer the product and has high safety. Moreover, since the die in the lower die assembly is fixedly installed on the lower die substrate, the accuracy is guaranteed and there is no friction and wear.

For stable operation, there are two horizontal slide rails 5 which are arranged parallel to each other, and a rail groove 51 matched with the horizontal slide rail 5 is arranged on the bottom surface of the lower die base 31. The lower die base 31 is connected with a horizontal drive mechanism 6, and the lower die base 31 is driven by the horizontal drive mechanism 6 to slide along the horizontal slide rail 5. Through the horizontal drive mechanism 6, the lower die assembly 3 can be slid out, and the lower die assembly 3 drives the product die and the product to be removed together, so as to facilitate the operator to transfer the product, and the safety is also guaranteed.
