Description

Technical Field

[0001] This utility model relates to the field of pressure roller swing arm technology, and in particular to a pressure roller swing arm connection structure. Background Technology

[0002] The swing roller and swing arm connection structure of the pressure roller mill is a key component to ensure stable pressure transmission of the swing roller. Its design needs to take into account strength, wear resistance and motion accuracy. High-precision bearings or self-lubricating spherical bearings are usually used to achieve low-friction transmission. At the same time, the reliable torque transmission is ensured by strengthening the pin, keyway or spline connection.

[0003] The existing roller press swing arm connection structure adopts a fixed design, and its length cannot be flexibly adjusted according to the actual working conditions. When it is necessary to adjust the height of the swing roller, the adjustment range of the swing roller is greatly limited due to the fixed length of the connection structure, resulting in low operational flexibility. This rigid connection method not only affects the adaptability of the equipment to materials of different thicknesses, but may also reduce production efficiency due to inconvenient adjustment.

[0004] Therefore, to address the problem that the length of the existing roller swing arm connection structure of the pressure roller cannot be adjusted during use, resulting in a large limitation on the height adjustment of the swing roller due to the connection structure and low flexibility, a new roller swing arm connection structure for the pressure roller can be designed. Utility Model Content

[0005] In order to overcome the problem that the length of the existing roller swing arm connection structure of the pressure roller cannot be adjusted during use, resulting in the roller swing height being greatly restricted by the connection structure and having low flexibility.

[0006] The technical solution of this utility model is as follows: a swing arm connection structure for a pressure roller machine, including a sleeve; it also includes a slide block and a lead screw. A rotating component is provided at the top of the sleeve, and a first bevel gear is connected to the bottom of the rotating component. The rotating component is used to drive the first bevel gear to rotate. Slide blocks are slidably connected to both the left and right ends inside the sleeve. A lead screw is threadedly connected to the end of each slide block near the first bevel gear. A second bevel gear is installed at the end of the lead screw near the first bevel gear. The first bevel gear and the second bevel gear mesh with each other. Two sets of support components for supporting the lead screw are provided inside the sleeve. A connector is installed at the end of each slide block away from the first bevel gear.

[0007] Preferably, by setting a rotating component, the first bevel gear can be driven to rotate. When the first bevel gear rotates, it can drive the two second bevel gears meshing with it to rotate synchronously, so that the two lead screws rotate under the cooperation of their respective support components. When the lead screws rotate, the slide block that is threaded with them can drive the connector to move left and right, thereby realizing the length adjustment of the entire device. This can adapt to the installation requirements of different swing roller arms, thus solving the problem that the length of the existing swing roller arm connection structure of the pressure roller machine cannot be adjusted during use, resulting in the swing roller being greatly restricted by the connection structure and having low flexibility when adjusting the height.

[0008] Preferably, the rotating assembly includes a connecting seat and a drive shaft; the top of the sleeve is provided with a connecting seat, the top of the connecting seat is inserted into the drive shaft, the bottom of the drive shaft is connected to the top of the first bevel gear, and the drive shaft is used to drive the first bevel gear to rotate.

[0009] Preferably, the rotating assembly also includes connecting rods and a rotating ring; three circumferentially distributed connecting rods are provided on the outer side of the drive shaft, and the outer sides of the three connecting rods are connected to the rotating rings.

[0010] Preferably, the support assembly includes support rods and positioning rings; two sets of left-right symmetrical support rods are installed inside the sleeve, with four support rods distributed circumferentially in each set, and positioning rings are connected to the ends of the four support rods, with the positioning rings being concentric with the lead screw.

[0011] Preferably, the support assembly also includes a bearing, with the bearing located inside the positioning ring, and the inner side of the bearing connected to the outer side of the end of the lead screw.

[0012] Preferably, positioning blocks are provided on both the front and rear sides of the two slides, and positioning grooves are provided on both the front and rear sides of the sleeve, with the positioning blocks and positioning grooves slidably connected.

[0013] Preferably, a fixing seat is provided at the right end of the sleeve, a pointer is installed on the front side of the fixing seat, and a scale line is provided on the front side of the right front positioning block.

[0014] The beneficial effects of this utility model are: By setting a connector that can move left and right, the connection structure between the swing roller arm and the transmission device can be freely adjusted in length, which significantly improves the flexibility and adaptability during installation. This design effectively solves the assembly difficulties caused by position deviation or dimensional error during the installation process of traditional fixed connection structures, enabling the equipment to adapt to different installation environments and space constraints. The adjustable characteristics of the connector not only simplify the installation process, but also reduce the stringent requirements for the machining accuracy of parts, thereby reducing the adjustment time and labor costs during installation, and further improving the practicality and economy of the overall structure.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5 This utility model provides an embodiment: a swing arm connection structure for a pressure roller, including a sleeve 1; it also includes a slide block 4 and a lead screw 5. A rotating assembly is provided at the top of the sleeve 1, and a first bevel gear 3 is connected to the bottom of the rotating assembly. The rotating assembly is used to drive the first bevel gear 3 to rotate. Slide blocks 4 are slidably connected to both the left and right ends inside the sleeve 1. A lead screw 5 is threadedly connected to the end of each slide block 4 near the first bevel gear 3. A second bevel gear 6 is installed at the end of the lead screw 5 near the first bevel gear 3. The first bevel gear 3 and the second bevel gear 6 mesh with each other. The internal part of the 1 has two sets of support components for supporting the lead screw 5. The two slides 4 are equipped with connectors 13 at the ends away from the first bevel gear 3. The first bevel gear 3 is driven to rotate by a rotating component. The first bevel gear 3 achieves dual-path synchronous output through meshing transmission with two second bevel gears 6, which drives the two lead screws 5 to rotate under the constraint of the support components. Under the action of thread transmission, the rotational motion of the lead screw 5 is converted into the linear displacement of the slide 4, which in turn drives the connectors 13 to move laterally, which can meet the installation position requirements of swing rollers and swing arms of different specifications.

[0019] Please see Figures 2-4In this embodiment, the rotating assembly includes a connecting seat 21 and a drive shaft 22; the top of the sleeve 1 is provided with a connecting seat 21, the top of the connecting seat 21 is inserted with the drive shaft 22, the bottom of the drive shaft 22 is connected to the top of the first bevel gear 3, and the drive shaft 22 is used to drive the first bevel gear 3 to rotate. By providing the connecting seat 21, there is damping between the drive shaft 22 and the connecting seat 21, and the drive shaft 22 can drive the first bevel gear 3 to rotate when rotating. The rotating assembly also includes a connecting rod 23 and a rotating ring 24; three rings are provided on the outer side of the drive shaft 22. The connecting rods 23 are distributed in a circle, and the outer sides of the three connecting rods 23 are connected to the rotating rings 24. By setting the connecting rods 23 and the rotating rings 24, it is convenient for the operator to rotate the transmission shaft 22 through the rotating rings 24, making the operation more labor-saving and convenient. The support assembly includes support rods 71 ​​and positioning rings 72. Two sets of left and right symmetrical support rods 71 ​​are installed inside the sleeve 1. Each set of support rods 71 ​​has four support rods distributed in a circle. The ends of the four support rods 71 ​​are connected to the positioning rings 72. The positioning rings 72 are concentric with the lead screw 5. The support rods 71 ​​are used to position and install the positioning rings 72.

[0020] Please see Figures 1-4 In this embodiment, the support assembly also includes a bearing 73. The bearing 73 is provided on the inner side of the positioning ring 72. The inner side of the bearing 73 is connected to the outer side of the end of the lead screw 5. By setting the bearing 73, the rotation of the lead screw 5 can be assisted, and the stability of the lead screw 5 during rotation can be improved. Positioning blocks 8 are provided on the front and rear sides of the two slides 4. Positioning grooves 9 are opened on the front and rear sides of the sleeve 1. The positioning blocks 8 and the positioning grooves 9 are slidably connected. By setting the positioning blocks 8 and the positioning grooves 9, the slides 4 can be limited, so as to prevent the lead screw 5 from driving the slides 4 to rotate synchronously when rotating, thereby ensuring transmission efficiency. A fixed seat 10 is provided on the right end of the sleeve 1. A pointer 11 is installed on the front side of the fixed seat 10. A scale line 12 is provided on the front side of the right front positioning block 8. By setting the pointer 11 and the scale line 12, it is convenient for the staff to observe the movement distance of the slides 4, thereby improving the docking accuracy.

[0021] During installation, the operator rotates the rotating ring 24, causing the transmission shaft 22 to drive the first bevel gear 3 to rotate. The meshing transmission between the first bevel gear 3 and the second bevel gear 6 causes the two lead screws 5 to rotate synchronously under the cooperation of the bearing 73. At this time, the slide 4, which is threaded with the lead screw 5, can drive the connector 13 to slide left and right. The operator can use the pointer 11 and the scale line 12 to observe the movement distance of the connector 13 at all times, thereby realizing the overall contraction or extension of the structure. Then, the two connectors 13 are connected to the swing roller and the drive structure respectively to complete the installation.

[0022] Through the above steps, the rotating component, as the power input end, drives the first bevel gear 3 to rotate. Its meshing characteristics distribute the torque equally to the two symmetrically arranged second bevel gears 6. This dual-path transmission design ensures that the two lead screws 5 can maintain completely synchronized speed and direction. Under the precise guidance of the support component, the rotating lead screw 5 converts the motion into the linear displacement of the slide block 4 through the threaded pair, thereby driving the connector 13 to move precisely along the axial direction. This adjustable mechanism provides a flexible installation and adaptation scheme for swing roller arms of different sizes by changing the relative position of the connector 13, so as to adapt to the installation requirements of different swing roller arms. This solves the problem that the length of the existing swing roller arm connection structure of the press roll cannot be adjusted during use, resulting in the swing roller being greatly restricted by the connection structure and having low flexibility when adjusting the height.
