Embodiment 1

[0025] A screen changing device for a paper machine, comprising an operating side frame 10, a support 1, a pin shaft 2, a support beam 3 and a jack, the operating side frame includes a column 13 and a column base 5, and the column 13 and the column base 5 pass through a joint The bolts are fixedly connected, and the support 1 is fixedly arranged on the column 13 of the operating side frame. One end of the support beam 3 is fixedly connected with the support 1 through the pin shaft 2. Horizontally rotated, a jack is arranged below the other end of the support beam 3 .

[0026] Wherein, the support 1 and the supporting beam 3 are correspondingly provided with positioning pin holes, and the positioning pin 4 is placed in the positioning pin holes to fix the supporting beam 3 . In the actual operation process of the screen changing device, when the screen is not needed to be changed, the support beam 3 is rotated to the horizontal direction of the screen part through the pin shaft...

Embodiment 2

[0028] A method of using the paper machine screen changing device described in Embodiment 1 to change the screen, comprising the steps of:

[0029] (1) First, the support beam 3 is rotated to a position perpendicular to the wire section in the horizontal direction with the pin shaft 2 as the rotation axis, and then the positioning pin 4 is inserted into the positioning pin hole on the support 1 and the support beam 3 The fixed support beam is not moved, and the new net to be replaced is placed on the support beam 3 for later use;

[0030] (2) Utilize the tensioner 6 to drive the guide roller 11 on the paper machine to move to the state where the net is relaxed, then open the joint bolt under the breast roller 14, and rotate the breast roller 14 in the same position as the breast roller lifting device 7 The position where the distance between the forming rollers 12 is the largest; then open the hinge bolts under the forming rollers 12, and pull out the forming roller extraction...

Abstract

The invention relates to a screen changing device for a paper machine and its application. It includes an operating side frame, a support, a support beam, a pin shaft and a jack. The operating side frame includes a column and a column base, and the column and the column base are fixed by joint bolts Connected, the support is fixed on the column on the operation side frame, one end of the support beam is fixedly connected with the support through the pin shaft, the support beam realizes horizontal rotation with the pin shaft as the rotation point, and a jack is set under the other end of the support beam , the advantage of the screen changing device of the present invention is that there is no need to set an extraction seat on the transmission side, and the operation is convenient when changing the screen, and the design of the screen changing device is ingenious, easy to install and use, and the effect is remarkable, which greatly improves the efficiency of the screen change.

Description

technical field [0001] The invention relates to a paper machine screen changing device and its application, belonging to the technical field of paper making equipment. Background technique [0002] During the working process of the paper machine, the polyester mesh plays the role of supporting and transmitting the paper sheets. The polyester mesh is covered with various rollers to run. The polyester net will be damaged to a certain extent. Due to the carrying of the paper, a certain amount of pulp and dirt will remain on the polyester net. At this time, the polyester net needs to be replaced in time to prevent the formation and drying of the paper. [0003] The general screen changing device has a dismantling type, a removable type, a set-in type and the like. The demolition type is mostly used in old-fashioned low-speed paper machines. When changing the screen, remove all the internal parts of the screen stroke, then put the new screen on the sleeve of the journal of the u...
