Description

Technical Field

[0001] The utility model relates to a paper pressing rod, in particular to a paper pressing rod for the edge of a paper sheet of a rewinding machine. Background Art

[0002] In toilet paper production, the rewinder section is the post-processing section of the paper machine. The main tasks of the rewinder are to rewind and slit the base paper. The base paper produced by the paper machine is all single-layered and very wide. The rewinder can produce and rewind base paper of different layers and widths. During the process of rewinding and slitting the base paper, due to the high speed of the rewinder, the left and right sides of the base paper are easily affected by the speed and airflow, causing vibration and fluttering. It is necessary to install two paper pressing rods on the left and right sides of the base paper to solve the vibration and fluttering of the rewound base paper. However, since the paper pressing rods are fixed, paper powder will accumulate on the surface of the paper pressing rods over time during the operation of the rewinder. The accumulated paper powder is easy to fall into the base paper for a long time, causing serious quality incidents and posing quality risks to the company and products, and also giving consumers a bad user experience. In addition, the paper pressing rods of some rewinding machines are fixed. In order to reduce the problem of paper powder accumulation during startup, an air pipe is installed on the paper pressing rod for blowing. This will directly increase the gas and electricity consumption in the actual production process. In addition, it cannot solve the problem of paper powder accumulation and falling well. Utility Model Content

[0003] Purpose of the utility model: The utility model aims to provide a paper edge pressing rod for a rewinder which can effectively avoid the problems of paper dust accumulation and paper breakage during feeding and does not require the installation of a purge device.

[0004] Technical solution: The paper edge pressing rod of the rewinding machine described in the utility model includes a paper pressing rod, a fixed connecting rod, a support frame and a base seat. The fixed connecting rod passes through the middle of the paper pressing rod and fixes the paper pressing rod on the support frame. The support frame is connected to the base seat at the bottom. The support frame includes at least two parts connected in an upper and lower manner. A gasket is provided at the connection between the upper and lower support frames, so that one end of the paper pressing rod is raised 5±2° compared to the other end.

[0005] Furthermore, after one end of the paper pressing rod is raised, there is space between the end of the paper pressing rod and the paper surface during operation, which will not cause the paper to float to the top of the paper pressing rod during paper feeding or at low vehicle speeds, causing paper breakage, nor will it cause paper powder accumulation problems.

[0006] Furthermore, the upper and lower support frames are fixed with screws, and gaskets are arranged above the screws.

[0007] Furthermore, grooves for installing movable wheels are provided on both sides of the paper pressing rod, and the movable wheels are embedded in the grooves on both sides of the paper pressing rod. The movable wheels drive the paper pressing rod to rotate when the rewinding machine is running.

[0008] Furthermore, the heights of the upper and lower support frames are adjustable.

[0009] Furthermore, the rewinding machine does not need to be equipped with a purge device.

[0010] Beneficial effects: Compared with the existing technology, the utility model has the following advantages: it can effectively avoid the problems of paper powder accumulation and paper breakage without installing a purge device, which can not only solve the related problems, but also reduce gas consumption, energy consumption and production costs; in addition, by adding rotating wheels on both sides of the paper pressing rod, the original fixed paper pressing rod can be transformed into a non-powered rotating paper pressing rod, further improving the problem of paper powder accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a structural diagram of the utility model. DETAILED DESCRIPTION

[0012] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0013] Figure 1 The accompanying drawings are marked as follows: 1-paper pressing rod, 2-fixed connecting rod, 3-support frame, 4-base seat, 5-gasket, 6-movable wheel.

[0014] Example

[0015] like Figure 1 As shown, the paper edge pressing rod of the rewinding machine described in the utility model includes: a paper pressing rod 1, a fixed connecting rod 2, a support frame 3 and a base seat 4. The fixed connecting rod 2 passes through the middle of the paper pressing rod 1 and is screwed to lock the movable wheel 6 and fix the paper pressing rod 1 on the support frame 3. The support frame 3 is connected to the base seat 4 at the bottom. The support frame 3 includes at least two parts connected in an upper and lower manner. The height of the upper and lower support frames is adjustable. A gasket 5 is provided at the connection between the upper and lower support frames, so that one end of the paper pressing rod 1 is raised by 5±2° compared to the other end. After one end of the paper pressing rod 1 is raised, there is space between one end of the paper pressing rod 1 and the paper surface during operation.

[0016] The upper and lower support frames are fixed with screws, and a gasket 5 is placed above the screws. The paper press rod 1 is 24 cm long and 4 cm in diameter. The paper press rod 1 needs to be made of a thick iron pipe. The pipe wall at both ends is turned on a lathe to form grooves according to the size of the movable wheels 6. Then the two wheels are inserted into the grooves on both sides of the paper press rod. The movable wheels 6 drive the paper press rod 1 to rotate when the rewinder is running.

[0017] On the one hand, the present invention sets a gasket at the connection between the upper and lower support frames so that one end of the paper pressing rod is raised 5±2° compared to the other end, so that the paper sheets at both ends are pressed down along the paper running direction with space left, which will not cause the paper sheets to float to the top of the paper pressing rod and cause paper breakage during paper feeding or low vehicle speed, and will not cause the problem of paper powder accumulation and falling. There is no need to install a purge device, which reduces gas consumption, energy consumption and production costs. On the other hand, the present invention adds rotating wheels to both sides of the paper pressing rod, which can transform the original fixed paper pressing rod into a non-powered rotating paper pressing rod, further improving the problem of paper powder accumulation.
