Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking equipment, and particularly relates to a frame facilitating felt replacement. Background Art

[0002] Papermaking felt is a valuable material in the papermaking industry. According to its uses, it can be divided into three categories: wet felt, upper felt, and dry felt. It plays a role in filtering water in the pulp and closely laminating the wet paper layers in multiple nets on the machine. The papermaking felt wears out relatively quickly and needs to be replaced regularly during shutdown to meet production requirements.

[0003] Due to different felt sizes, in the prior art, when replacing a larger-sized felt, generally a traveling crane boom is used to lift the felt, and then workers manually arrange the hanging felt and fit the felt onto the shaft roller. The shutdown time for replacing the felt is relatively long. Therefore, during production, the shutdown time for replacing the felt causes great production capacity losses. Content of the Utility Model

[0004] The purpose of the utility model is to provide a frame facilitating felt replacement to solve the technical problems of the complicated felt replacement process and reduced production efficiency in existing production.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A frame facilitating felt replacement includes a frame. A reinforcing plate is fixedly connected to the top end of the frame, and a lifting lug is fixedly connected to the top end of the reinforcing plate. A transmission chamber is opened inside the frame. Symmetrically arranged sliding grooves are opened on both sides of the frame. A bidirectional lead screw is horizontally rotatably connected to the frame. Symmetrically arranged transmission plates are threadedly connected to the bidirectional lead screw. Extrusion grooves are opened on the transmission plates. Support rods are arranged in the extrusion grooves. One end of the support rod far away from the extrusion groove is fixedly connected with a rubber layer. Symmetrically arranged limiting plates are arranged on one side of the frame. Limiting grooves are opened on the sides of the limiting plates close to the frame. Grooves are opened at one ends of the support rods far away from the rubber layer.

[0007] As a preferred scheme of the utility model, one end of the bidirectional lead screw far away from the frame is fixedly connected with a transmission disc, and the surface of the transmission disc is designed with an anti-slip structure.

[0008] As a preferred scheme of the utility model, the limiting groove is designed with an H-shaped structure, and one end of the support rod provided with the groove is slidably connected with the limiting groove.

[0009] As a preferred scheme of the utility model, the support rods are correspondingly arranged with the extrusion grooves opened on the transmission plates, and the support rods are slidably connected with the extrusion grooves opened on the transmission plates.

[0010] As a preferred scheme of the utility model, the sliding grooves are designed with an inclined structure, and the support rods are slidably connected with the sliding grooves opened on the transmission plates.

[0011] Compared with the prior art, the beneficial effects of a machine frame facilitating the replacement of the felt cloth proposed by the present utility model are as follows: Through the structural design of the lead screw, sliding groove, transmission plate, and support rod, it is only necessary to set the cloth pulling sleeve on the support rod, and by rotating the transmission plate, the cloth pulling can be tractioned through the support rod, so as to control the shape of the hoisted cloth pulling, facilitate the sleeving of the cloth pulling on the paper machine shaft roller, reduce the downtime for replacing the felt cloth, and has a simple structure and is convenient to use.

[0021] See Figures 1-4 As shown, an embodiment of the utility model provides a frame facilitating felt replacement, which includes a frame 1. A reinforcing plate 2 is fixedly connected to the top end of the frame 1, and a lifting lug 3 is fixedly connected to the top end of the reinforcing plate 2. A transmission chamber 4 is formed inside the frame 1. Symmetrically arranged sliding grooves 5 are formed on both sides of the frame 1. A bidirectional lead screw 6 is rotatably connected to the frame 1 horizontally. Symmetrically arranged transmission plates 7 are threadedly connected to the bidirectional lead screw 6. Extrusion grooves 8 are formed on the transmission plates 7. Support rods 9 are arranged in the extrusion grooves 8. One end of the support rod 9 away from the extrusion groove 8 is fixedly connected with a rubber layer 10. On one side of the frame 1, symmetrically arranged limiting plates 11 are provided. Limiting grooves 12 are formed on the side of the limiting plate 11 close to the frame 1. Grooves 13 are formed at one end of the support rod 9 away from the rubber layer 10.

[0022] One end of the bidirectional lead screw 6 away from the frame 1 is fixedly connected with a transmission disc 14. The surface of the transmission disc 14 is designed with an anti-slip structure, which is convenient for rotating the transmission disc 14 to drive the bidirectional lead screw 6. The limiting groove 12 is designed with an H-shaped structure. One end of the support rod 9 provided with the groove 13 is slidably connected with the limiting groove 12, which is convenient for the limiting groove 12 to limit the support rod 9. The support rod 9 is correspondingly arranged with the extrusion groove 8 formed on the transmission plate 7, and the support rod 9 is slidably connected with the extrusion groove 8 formed on the transmission plate 7, which is convenient for the extrusion groove 8 to drive the support rod 9 by extrusion. The sliding groove 5 is designed with an inclined structure, and the support rod 9 is slidably connected with the sliding groove 5 formed on the transmission plate 7, which is convenient for the support rod 9 to move along the direction of the sliding groove 5.

[0023] When the embodiment of the utility model is used, the felt is sleeved on the support rod 9. The transmission disc 14 is rotated. The transmission disc 14 drives the bidirectional lead screw 6 to rotate. The bidirectional lead screw 6 drives the threadedly connected transmission plate 7 to move. While moving, the transmission plate 7 extrudes the support rod 9. The stressed support rod 9 moves along the direction of the sliding groove 5 formed on the frame 1. After the moving support rod 9 pulls the sleeved felt into a suitable length and width, a traveling crane is started. The frame 1 and the felt are hoisted to the side of the paper machine to be installed by the traveling crane. After the frame 1 is aligned with the roll to be sleeved, the felt is transferred and sleeved on the roll.
