Embodiment 1

[0030] Example 1 as figure 1 Shown in —4, there are forming seat and pressure bar; The inner peripheral surface of described forming seat 5 is inner cylindrical surface 1, and there is a cylindrical mandrel 6 on the bottom surface axis of forming seat 5, and the bottom surface surrounds mandrel 6 and has 3 A pit, the pit has a working surface 7 and an auxiliary surface 3, the outermost edge of the auxiliary surface 3 and the outermost edge of the working surface 7 are on the same surface to form a paper tube forming surface 2, the paper tube forming surface 2 is a plane and Vertical to the axis of the forming seat 5. The innermost edge of the auxiliary surface 3 coincides with the innermost edge of another adjacent working surface. The working surface 7 is a plane, and the auxiliary surface 3 is a curved surface. The intersection of the adjacent auxiliary surface 3 b and the inner cylindrical surface 1 is an arc surface 4 . There is a hole 8 in the pit to communicate with t...

Embodiment 2

[0031] Example 2 as Figure 5 -7, it differs from Embodiment 1 in that the outermost edge of the auxiliary surface 20 intersects with the outermost edge of the working surface 19 to form the paper tube forming line 18.

Embodiment 3

[0032] Example 3 as Figure 8 -10, it differs from Embodiment 2 in that the paper tube forming line 21 is a curve convex to the forming seat 5, and the front end 22 of the pressure rod head 23 is a curved surface convex inward.

Abstract

The invention discloses a forming mold of a perforated bottom of a paper pipe. The forming mold comprises a forming seat and a pressing rod. The inner circumferential face of the forming seat is an inner cylindrical face, and a cylindrical core shaft is arranged on the axis of the bottom face of the forming seat; a pit is formed in the bottom face around the core shaft, and the pit is provided with a work face and an auxiliary face; the outmost edge of the auxiliary face and the outmost face of the work face intersect to form a paper pipe forming line; or the outmost edge of the auxiliary face and the outmost edge of the work face are located on the same face to form a paper pipe forming face; and the innermost edge of the auxiliary face and the innermost edge of the work face coincide. The pressing rod is a cylindrical rod, a hole is formed in the front end of the pressing rod in the axial direction, and a flange is arranged on the outer circumferential face of the rear end of the pressing rod. Compared with the prior art, the forming mold has the beneficial effects of being simple in structure, high in reliability, simplifying procedures, reducing the cost, increasing the product number and improving product quality.

Description

technical field [0001] The invention relates to a paper product processing device, in particular to a paper tube forming mold with a hole bottom. Background technique [0002] Paper tubes with holes in the bottom are needed in many places in daily life and production, and these paper tubes with holes in the bottom are assembled from the tube body and the bottom of the tube with holes. The manufacturing process is complicated and the cost is high. In the production of fireworks, one end of some paper tubes must be closed, leaving only one hole. The traditional process is commonly known as "mud head". hole. This method requires a large amount of soil, which damages the environment, and the soil pollutes the environment after the fireworks are set off. Manual "cracking" is labor-intensive, the working environment is poor, and the production efficiency is low. However, the mechanical "mud pressing head" has a large footprint, complex structure and poor reliability. Recently,...
