[0021] The present application provides a paper roller brake device for a paper machine. Figures 1 to 3 , Figure 1 1 is a schematic diagram of the overall structure of an embodiment of a paper roller brake device for a paper machine according to the present application. Figure 2 yes Figure 1 A schematic structural diagram of the paper roller brake device from another perspective in the embodiment, Figure 3 yes Figure 1 Schematic diagram of the disassembled structure of the paper roller brake device in the embodiment; the paper roller brake device 100 for a paper machine includes but is not limited to the following structures: a bracket 110, an elastic member 120, and a friction plate 130.
[0022] Specifically, the two ends of the elastic member 120 are respectively connected to the bracket 110 and the friction plate 130. The bracket 110 is used to be fixedly connected to the paper machine equipment. The side of the friction plate 130 facing away from the elastic member 120 is used to frictionally contact with the paper roller, thereby slowing down the rotation of the paper roller. The elastic member 120 is used to buffer the impact force between the friction plate 130 and the bracket 110.
[0023] Optionally, the elastic member 120 in this embodiment may be a structural member such as a compression spring, an elastic material block, etc., and the friction plate 130 may be made of a wear-resistant material such as rubber.
[0024] Optionally, see Figure 2 and Figure 3 The paper roller brake device 100 in this embodiment further includes a support member 140 and a connecting member 150. The support member 140 is disposed between the friction plate 130 and the elastic member 120. One end of the connecting member 150 is fixedly connected to the support member 140, and the other end is hinged to the bracket 110. A connecting seat 160 is fixedly disposed on the bracket 110, and a pin shaft 170 is disposed on the connecting seat 160. The connecting member 150 is hinged to the connecting seat 160 through the pin shaft 170.
[0025] The bracket 110 in this embodiment may include a connecting plate 111 and a supporting plate 112. The connecting plate 111 is used to be fixedly connected to the paper machine equipment, and the connecting seat is fixedly connected to the supporting plate 112. The connecting plate 111 and the supporting plate 112 may be an integral structure, and the material may be a steel plate.
[0026] Optionally, see Figure 2 and Figure 3 The paper roller brake device 100 in this embodiment further includes an adjusting member 180, which is connected to the support plate 112 of the bracket 110 and can be extended and retracted relative to the support plate 112. The adjusting member 180 supports the elastic member 120. The adjusting member 180 in this embodiment is a bolt, which is inserted into a connecting hole 1120 on the support plate 112 of the bracket 110. By adjusting the position of a nut 181 on the bolt, the fixed position of the connecting member 180 relative to the support plate 112 is adjusted, thereby adjusting the supporting height of the elastic member 120 and changing the friction contact position between the friction plate 130 and the paper roller.
[0027] The paper roller brake device for a paper machine provided in the embodiment of the present application is designed with a structure in which an elastic part and a friction plate are matched. On the one hand, the friction contact between the friction plate and the paper roller is utilized to decelerate the rotation of the paper roller and prevent the paper roller from reversing. On the other hand, the elastic part can be used to buffer the impact force between the friction plate and the bracket, thereby reducing the impact on the paper roller and increasing the service life. At the same time, the rewinding efficiency is improved and the probability of abnormal situations is reduced.
[0028] The paper roller brake device of the paper machine in the embodiment of the present application is that the empty roller rotates by itself, and when the empty roller reaches the blocker, it contacts the brake pad (friction pad) of the brake device, and the self-rotating empty roller in place is braked by the action of the spring and the brake pad to prevent the empty roller from reversing due to the weight of the residual paper sheets in the empty roller. After the empty roller is in place, the weight of the residual paper sheets causes the empty roller to reverse, causing the paper sheets to fall into the empty roller bracket and the mother roll. Through the automatic brake device in the embodiment itself, after the empty roller is in place and contacts the automatic brake device, the empty roller is prevented from reversing, ensuring that the empty roller does not affect the rewinding operation while improving the rewinding efficiency.
[0029] In addition, an embodiment of the present application also provides a paper machine, which includes the paper roller brake device and paper cutting or automatic paper rolling equipment in the aforementioned embodiment. The detailed features of this part are within the scope of understanding of technicians in this field and will not be repeated here.
[0030] The paper machine in the embodiment of the present application can realize automatic braking of the paper roller to prevent the empty roller residual paper sheet from reversing due to its own weight, improve the efficiency of large rewinding and reduce manpower. No. 1 large rewinder has about 790 rolls per month, each roll has 7 strips of adhesive tape, each strip is 0.5 meters, and the length of tape used per month is 790*0.5*7=2765 meters. Converted into 55.3 rolls of tape rolls. It can save = 55 rolls * 23 (unit price of each roll of tape) = 1265*12 months = 15180 yuan / year. It can also improve production efficiency.
[0031] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
