Description
Technical Field
The invention relates to a paper product processing device, in particular to a paper tube bottom forming die.
Background
In daily life and in many places of production, paper tubes with bottoms are needed, and the paper tubes with bottoms are assembled by two parts of a tube body and a tube bottom, so that the manufacturing process is complex and the cost is high. In firework production, one end of a paper tube is required to be sealed, and the traditional procedure is commonly called as 'beating mud head', namely, soil is compacted at one end of the paper tube, so that a mud layer for blocking and isolating is formed. This practice requires a lot of soil, which damages the environment, and the soil pollutes the environment after the fireworks are set off. The manual 'mud beating head' has the advantages of high labor intensity, poor working environment and low production efficiency. The mechanical mud pressing head has large occupied area, complex structure and poor reliability. Recently, the mud head is replaced by a circular paper sheet, i.e. the circular paper sheet is punched out first and then pressed into the paper tube. The method is time-consuming and labor-consuming in manual operation, high in mechanical cost, and low in sealing effect of the round paper sheet and the inner wall of the paper tube, and the quality of the product is affected.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the paper tube bottom forming die which is simple in structure, low in cost, safe and reliable.
The invention adopts the following technical scheme.
A paper tube bottom forming die comprises a forming seat and a pressing rod, wherein the inner circumferential surface of the forming seat is an inner cylindrical surface, 1 pit or 2 pits or 3 pits or 4 pits are arranged on the bottom surface of the forming seat, each pit is provided with a working surface and an auxiliary surface, the working surface is a plane, the auxiliary surface is a curved surface, the outermost edge of the auxiliary surface and the outermost edge of the working surface are positioned on the same plane to form a paper tube forming surface, the paper tube forming surface is a plane and is perpendicular to the axis of the forming seat, the pressing rod is divided into a pressing rod head and a pressing rod body, the front end of the pressing rod head is axially provided with a hole, the tail of the pressing rod head is slidably inserted into a long hole of the pressing rod body and is contacted with a pressure spring in the long hole, a pin is fixed on the pressing rod head through a groove of the pressing rod body, the outer circumferential surface of the pressing rod body is provided with a flange, and the pits are provided with a hole and the outer circumferential surface of the forming seat is communicated.
The bottom surface of the forming seat is provided with any one of 5 to 20 pits, each pit is provided with a working surface and an auxiliary surface, the working surface is a plane, the auxiliary surface is a curved surface, the outermost edge of the auxiliary surface and the outermost edge of the working surface are positioned on the same surface to form a paper tube forming surface, the paper tube forming surface is a plane and is perpendicular to the axis of the forming seat, and the innermost edge of the auxiliary surface is overlapped with the innermost edge of another adjacent working surface.
The intersection of the auxiliary surface and the inner cylindrical surface is an arc surface.
The front end of the compression bar is a plane.
Compared with the prior art, the invention has the advantages of simple structure, high reliability, simplified working procedures, reduced cost and improved quantity and quality of products.
