Description

Technical Field

[0001] This utility model belongs to the field of high-speed papermaking equipment manufacturing, specifically relating to a tension roll assembly with a drag chain. Background Technology

[0002] The tension roll assembly is a component of the paper machine's wire mesh operation. It is a device used to adjust the wire mesh tension and an important tool to ensure the normal operation of the wire mesh. During use, operators can adjust the position of the tension roll according to actual needs, thereby adjusting the wire mesh tension by changing the position of the tension roll. However, in practical use, the existing tension roll assembly is inconvenient to adjust. Furthermore, during the position adjustment process, the oil pipes used for lubrication between the tension roll and the bearing housing are not effectively protected. As a result, the oil pipes are prone to damage and breakage due to friction during the movement of the tension roll, affecting the overall performance. Therefore, to solve the above problems, it is necessary to develop a tension roll assembly with a drag chain that is easy to operate and has a reasonable structural design. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tension roller assembly with a drag chain that is easy to operate and use and has a reasonable structural design.

[0004] The purpose of this utility model is achieved as follows: A tensioning roller assembly with a drag chain includes a fixed base plate, an intermediate mounting plate, a roller body, and a drag chain assembly. The fixed base plate is horizontally placed and fixedly connected to the paper machine frame. The intermediate mounting plate is inclined and consists of two plates, located at the front and rear ends of the upper surface of the fixed base plate, respectively. A support plate a is vertically fixed between the left end of the lower surface of the intermediate mounting plate and the upper surface of the fixed base plate, and a support plate b is vertically fixed between the right end of the lower surface of the intermediate mounting plate and the upper surface of the fixed base plate. An adjusting slide rail is fixedly connected to the upper end of the support plate via a support. The height of support plate a is lower than the height of support plate b. The adjusting slide rail is flush with the intermediate mounting plate. An electric adjusting trolley is slidably mounted on the upper end of the rail along its length. A connection port is provided in the middle of the left side of the electric adjusting trolley, and a bearing seat is connected to it above by fixing bolts. The roller is longitudinally rotatably positioned between the two bearing seats. There are two cable chain assemblies, located in the middle of the front end of the upper surface of the fixed base plate and the middle of the rear end of the upper surface, respectively. Each assembly includes a cable chain mounting frame and a cable chain body. The cable chain mounting frame is horizontally arranged and fixedly connected to the upper surface of the fixed base plate. The cable chain body is placed above the cable chain mounting frame, with its right end fixedly connected to the cable chain mounting frame and its left end limitedly connected to the connection port in the electric adjusting trolley on the same side. A lubricating oil pipe passes through the inside of the cable chain body.

[0005] Furthermore, limit blocks are fixedly installed at both the left and right ends of the upper surface of the adjusting slide rail.

[0006] Furthermore, a positioning block is formed by an upward protrusion in the middle of the upper surface of the electric adjustment trolley, and a positioning groove that matches the structure of the positioning block is provided on the lower surface of the bearing seat.

[0007] Furthermore, reinforcement members are fixedly provided on both sides of the connection between the upper end of the support plate a and the lower surface of the intermediate mounting plate, as well as on both sides of the connection between the upper end of the support plate b and the lower surface of the intermediate mounting plate.

[0008] Furthermore, the tilt angle of the intermediate mounting plate is 15 degrees. o .

[0009] The beneficial effects of this utility model are as follows: By setting support plate a and support plate b, and utilizing the height difference between support plate a and support plate b, combined with their vertical support, the intermediate mounting plate can be installed at an inclined position on the upper part of the fixed base plate. By setting up the sliding rail, electric adjusting trolley, bearing seat and roller, and utilizing the sliding connection between the electric adjusting trolley and the adjusting rail, and the limiting connection between the bearing seat and the electric adjusting trolley achieved by fixing bolts, in use, by simultaneously controlling the electric adjusting trolley at the upper end of the two adjusting rails to move synchronously, the bearing seat above the electric adjusting trolley can be moved synchronously. In turn, through the synchronous movement of the two bearing seats, the roller that is longitudinally rotated between them can be moved. Thus, while the roller is moving, the tension of the outer mesh can be adjusted.

[0010] This utility model, by setting up a cable chain mounting bracket and a connecting port, utilizes the cooperation of the cable chain mounting bracket and the connecting port to achieve limited installation of the cable chain body between the fixed base plate and the electric adjusting trolley. Thus, the connection between the cable chain body and the lubricating oil pipe protects the lubricating oil pipe, thereby preventing the oil pipe from being damaged or broken due to friction during the movement of the tension roller. In summary, this utility model has the advantages of convenient operation and reasonable structural design. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Example: Figure 1 , Figure 2 As shown, a tension roll assembly with a drag chain includes a fixed base plate 1, an intermediate mounting plate 2, a roll body 3, and a drag chain assembly 4. The fixed base plate 1 is horizontally placed and fixedly connected to the paper machine frame. The intermediate mounting plate 2 is inclined and consists of two plates, located at the front and rear ends of the upper surface of the fixed base plate 1, respectively. A support plate a11 is vertically fixed between the left end of the lower surface of the intermediate mounting plate 2 and the upper surface of the fixed base plate 1, and a support plate b12 is vertically fixed between the right end of the lower surface of the intermediate mounting plate 2 and the upper surface of the fixed base plate 1. An adjusting slide rail 5 is fixedly connected to the upper end of the intermediate mounting plate 2 via a support 21. The height of the support plate a11 is lower than the height of the support plate b12. The adjusting slide rail 5 is flush with the intermediate mounting plate 2, and the upper end of the adjusting slide rail 5 extends along its length. An electric adjusting trolley 6 is slidably installed in the direction of the angle. The electric adjusting trolley 6 has a connection port 61 in the middle of its left side and a bearing seat 7 connected to it by a fixing bolt. The roller body 3 is longitudinally rotatably arranged between the two bearing seats 7. There are two cable chain assemblies 4, located in the middle of the front end and the middle of the rear end of the upper surface of the fixed base plate 1, respectively. Each cable chain assembly includes a cable chain mounting frame 41 and a cable chain body 42. The cable chain mounting frame 41 is arranged horizontally and is fixedly connected to the upper surface of the fixed base plate 1. The cable chain body 42 is placed above the cable chain mounting frame 41. Its right end is fixedly connected to the cable chain mounting frame 41, and its left end is limitedly connected to the connection port 61 in the electric adjusting trolley 6 on the same side. A lubricating oil pipe passes through the inside of the cable chain body 42.

[0016] Limiting blocks 51 are fixedly installed at the left and right ends of the upper surface of the adjusting slide rail 5. These limiting blocks 51 limit the movement range of the electric adjusting trolley 6 along the adjusting slide rail 5. A positioning block protrudes upward from the middle of the upper surface of the electric adjusting trolley 6. A positioning groove matching the positioning block structure is provided on the lower surface of the bearing seat 7. The positioning block and positioning groove facilitate the positioning of the bearing seat 7 above the electric adjusting trolley 6, thereby improving the ease of operation when the bearing seat 7 and the electric adjusting trolley 6 are connected. Reinforcing members 13 are fixedly installed on both sides of the connection between the upper end of the support plate a11 and the lower surface of the intermediate mounting plate 2, and on both sides of the connection between the upper end of the support plate b12 and the lower surface of the intermediate mounting plate 2. These reinforcing members 13 increase the stability of the connection between the support plates a11, b12, and the intermediate mounting plate 2. The tilt angle of the intermediate mounting plate 2 is 15°. o .

[0017] In use, this invention utilizes the sliding connection between the electric adjusting trolley 6 and the adjusting slide rail 5, along with the limiting connection between the bearing seat 7 and the electric adjusting trolley 6 achieved by fixing bolts. By simultaneously controlling the synchronous movement of the electric adjusting trolleys 6 at the upper ends of the two adjusting slide rails 5, the bearing seats 7 above the electric adjusting trolleys 6 move synchronously. This synchronous movement of the two bearing seats 7 then drives the longitudinally rotating roller 3 positioned between them to move. Thus, while the roller 3 moves, the tension of the externally wound mesh can be adjusted. Simultaneously, the cooperation of the drag chain mounting bracket 41 and the connecting port 61... This invention enables the cable chain body 42 to be positioned between the fixed base plate 1 and the electric adjusting trolley 6. By utilizing the connection between the cable chain body 42 and the lubricating oil pipe, the lubricating oil pipe is protected, thus solving the problem of oil pipe damage and rupture due to friction during the movement of the tension roller. Furthermore, by setting support plates a11 and b12 of different heights, the height difference between support plates a11 and b12, combined with their vertical support, allows for the inclined fixed installation of the intermediate mounting plate 2 on the upper end of the fixed base plate 1. In summary, this invention has the advantages of convenient operation and reasonable structural design.
