Description

Technical Field

[0001] The utility model relates to a driving roller with quick installation. Background Art

[0002] The roller, also known as a roll, is a cylindrical part, divided into driving and driven rollers. It is widely used as a transmission workpiece in various transmission and conveying systems such as rotary screen printing machines, digital printers, mine conveying equipment, papermaking and packaging machinery. Generally, the structure is integral, that is, rotating mechanisms are fixedly connected to both ends of the driving roller. It is necessary to sleeved the support seats on both ends of the roller and then fix the support seats. When the driving roller is worn and needs to be installed or replaced, it is necessary to remove the main body of the driving roller and the relevant rotating mechanisms together, and then replace it with a new conveying roller. In this way, the production cost is greatly increased and the steps are also cumbersome.

[0003] If a separated structure is adopted, it will cause the main structure of the driving roller to be too complex. During the disassembly process, especially in the narrow space inside the machine tool, it is still necessary to disassemble the rotating structure first, resulting in too long maintenance time, seriously affecting the processing efficiency and further increasing the production cost.

A roller column is fixedly provided on the outer side of the moving block; a control component for controlling the sliding of the moving block is fixedly provided at the notch of the grooves.

[0006] Furthermore, the control component includes a fixed ring plate fixedly arranged at the notch of the grooves. A main through groove is provided on the fixed ring plate along the sliding direction of the moving block. A plurality of secondary through grooves are provided on the main through groove, which are evenly spaced along the extending direction of the main through groove and communicated with the main through groove. A locking groove communicated with the secondary through groove is provided on each secondary through groove, and the locking groove extends towards the roller column; the control component further includes a control block with one end fixedly arranged on the moving block and the other end capable of passing through the main through groove, the main through groove and the locking groove and sliding between the main through groove, the main through groove and the locking groove; the moving block slides in the grooves under the sliding of the control block in the main through groove. The moving block forms a radial movement limit after the control block slides from the main through groove to the secondary through groove, and the moving block forms an axial movement limit after the control block slides from the secondary through groove to the locking groove.

[0007] Furthermore, there are multiple main through grooves which are circumferentially distributed on the fixed ring plate along the axial direction of the moving block, and there are also multiple control blocks which are arranged in one-to-one correspondence with the respective main through grooves.

[0008] Furthermore, a driving ring is also provided. The driving ring is sleeved outside the fixed ring plate. The inner wall of the driving ring is fixedly connected to one end of each control block passing through the fixed ring plate. Each control block slides synchronously by driving the driving ring to move or rotate.

A ball is arranged in each card slot. The upper half of the ball protrudes from the notch of the card slot, and the lower half of the ball is located inside the card slot. A second spring is also arranged inside each card slot. One end of the second spring is fixedly arranged at the bottom of the card slot, and the other end of the second spring is fixedly connected to the lower half of the ball.

[0010] Furthermore, on the inner wall of the groove, there are multiple sliding grooves which are circumferentially distributed along the axial direction of the groove. On the part of the moving block located in the groove, there are multiple sliders which are arranged in one-to-one correspondence with the sliding grooves and can form a sliding fit with the sliding grooves. The moving block is slidably arranged in the groove through the sliding fit between the sliders and the sliding grooves.

[0011] The utility model has positive effects: (1) Grooves are provided at both ends of the roller body of the utility model. A moving block is slidably arranged in the groove. A first spring is also arranged in the groove. One end of the first spring is fixedly arranged at the bottom of the groove, and the other end of the first spring acts on one end of the moving block located in the groove. A roller is fixedly arranged on the outer side of the moving block; by controlling the movement of the moving block, the roller is driven to move, and the rollers at both ends of the roller body can be quickly disassembled or installed on the mounting rack, which is efficient and fast.

[0012] (2) The control assembly of the utility model includes a fixed ring plate fixedly arranged at the groove opening. The fixed ring plate is provided with a main through groove, a secondary through groove and a locking groove, and the locking groove extends towards the roller; the control assembly also includes a control block. The moving block slides in the groove under the sliding of the control block in the main through groove. The moving block forms a radial movement limit after the control block slides from the main through groove to the secondary through groove, and the moving block forms an axial movement limit after the control block slides from the secondary through groove to the locking groove; by changing the position of the control block on the fixed ring plate, the positions of the moving block and the roller are controlled, which is convenient for operation.

A ball is provided in each card slot, and a second spring is further provided inside each card slot. One end of the second spring is fixedly arranged at the bottom of the card slot, and the other end of the second spring is fixedly connected to the lower part of the ball. When the roller column enters the installation position, the balls on the roller column are squeezed. After the roller column passes through the installation position, the balls rebound under the action of the second spring, thereby limiting the position of the roller column.

[0015] (5) On the inner wall of the groove of the present utility model, there are a plurality of sliding grooves circumferentially distributed along the axial direction of the groove. On the part of the moving block located in the groove, there are a plurality of sliders arranged in one-to-one correspondence with the sliding grooves and capable of forming a sliding fit with the sliding grooves. When the sliders form a fit with the sliding grooves, it can prevent the moving block from sliding out of the groove. At the same time, due to the cooperation between the control block and the main through groove, it can also prevent the moving block from sliding out of the groove. Description of the Drawings
