Description

Technical Field

[0001] The utility model belongs to the technical field of roller devices, and particularly relates to an adaptive spacing adjustment roller device. Background Art

[0002] Material transfer rollers have gradually emerged and evolved with the development of industrial production. In the early days of industrial production, in order to move and transport materials, people began to try various simple devices. Initially, materials might be pushed through chutes or flat plates, but this method was inefficient and prone to damaging the materials. With the progress of technology and the continuous pursuit of production efficiency, the concept of rollers was gradually introduced. The main function of material transfer rollers is to efficiently and smoothly transport various materials. It can greatly reduce the friction between the materials and the conveying surface, enabling the materials to slide or roll easily on the rollers, thereby saving labor and increasing the conveying speed. In the manufacturing industry, metal sheets can be powerfully and orderly conveyed;

[0003] The deficiencies of existing adaptive spacing adjustment roller devices: The position of the rollers is usually adjustable to a certain extent. However, this adjustability has obvious limitations in practical applications. Especially when dealing with metal sheets of different thicknesses, manual adjustment is required for the spacing between the rollers. This means that every time different thicknesses of metal sheets are encountered, the staff must stop the ongoing production process and manually operate the device for adjusting the roller spacing. This completely manual intervention method is not only inefficient, but also the manual adjustment cannot respond in real time to changes in the thickness of the metal sheets, and cannot achieve instant, flexible, and adaptive spacing adjustment. This makes it difficult to ensure accurate and fast transmission when dealing with continuous metal sheets with continuously changing thicknesses. Content of the Utility Model

[0004] To solve the problems raised in the above background art, the utility model provides an adaptive spacing adjustment roller device, which includes two support plates and an adaptive adjustment structure located on the left side and inside of the two support plates. Four chutes are provided on the mutually approaching surfaces of the two support plates and are evenly divided into two groups. Through grooves are provided on the left inner walls of the chutes;

[0005] The adaptive adjustment structure includes a hydraulic buffer rod fixedly installed on the inner wall of the chute and a movable block fixedly connected to one end of the hydraulic buffer rod close to each other, and a limiting plate erected on the outer wall of the support plate. Connecting rods are fixedly installed on the left side surfaces of the two groups of movable blocks. The middle parts of the two groups of connecting rods are rotationally connected to the inner wall of the limiting plate through rotating rods. Guide wheels are fixedly installed on the mutually approaching surfaces of the two groups of connecting rods. A roller is rotationally connected to the mutually approaching surface of the limiting plate. A spring is sleeved on the outside of the hydraulic buffer rod.

[0006] Preferably, the number of the connecting rods is set to four and they are evenly divided into two groups, and two of the connecting rods are distributed in an X shape.

[0007] Preferably, the movable blocks are all slidably connected to the inner wall of the chute.

[0008] Preferably, one side of the connecting rod away from the movable block passes through the through groove and extends to the left side of the limiting plate.

[0009] Preferably, it further includes two stabilizing plates located in the middle of the two support plates.

[0010] Preferably, the number of the roller shafts is set to two, and equal gaps are left between the middle parts of the two roller shafts and the middle parts of the two guide wheels.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Through the design of the adaptive adjustment structure of the present utility model, when facing metal sheets with different thicknesses, the metal sheet will first come into contact with the guide wheels. If the thickness of the metal sheet is less than the gap between the two pre-set guide wheels, then the metal sheet can smoothly pass through the gap in the middle of the guide wheels without any hindrance. Immediately afterwards, it will naturally pass through the gap between the two roller shafts. However, when the thickness of the metal sheet is greater than the gap between the two guide wheels, the metal sheet will be in contact with the guide wheels, and during this continuous extrusion process, the connecting rod will move under the precise rotation mechanism of the rotating shaft. As the connecting rod moves, it will drive the movable block to perform a corresponding displacement, and this displacement will cause the spring and the hydraulic buffer rod to be squeezed by the movable block. During this process, the hydraulic buffer rod can effectively absorb and buffer part of the impact force. At the same time, when the movable block moves, it will drive the two roller shafts to move synchronously. This synchronous movement mechanism makes the distance between the two roller shafts gradually increase, thereby providing enough passing space for the thicker metal sheet. When the thicker metal sheet finally successfully passes through between the two roller shafts, since the thin sheet is no longer in contact with the guide wheels, the elastic potential energy stored in the spring starts to be released at this time. This energy drives the movable block, the roller shafts and the connecting rod to quickly reset to the initial state, thereby greatly improving the efficiency and versatility of processing metal sheets with different thicknesses on the production line.

Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1 to 5 shown, the present utility model provides an adaptive spacing adjustment roller shaft device, including two support plates 1 and an adaptive adjustment structure 2 located on the left side and inside of the two support plates 1. Four chute 11 are provided on the mutually approaching surfaces of the two support plates 1 and are evenly divided into two groups. Through grooves 12 are provided on the left inner walls of the chute 11;

[0021] The adaptive adjustment structure 2 includes a hydraulic buffer rod 21 fixedly installed on the inner wall of the chute 11 and a movable block 22 fixedly connected to the mutually approaching end of the hydraulic buffer rod 21, and a limit plate 23 erected on the outer wall of the support plate 1. Connecting rods 24 are fixedly installed on the left side surfaces of the two groups of movable blocks 22. The middle parts of the two groups of connecting rods 24 are rotationally connected to the inner wall of the limit plate 23 through rotating rods 25. Guide wheels 26 are fixedly installed on the mutually approaching surfaces of the two groups of connecting rods 24. A roller shaft 27 is rotationally connected to the mutually approaching surface of the limit plate 23. A spring 28 is sleeved on the outside of the hydraulic buffer rod 21.

[0022] Adopting the above - mentioned solution: Through the design of the adaptive adjustment structure 2, when facing metal sheets with different thicknesses, the metal sheet first comes into contact with the guide wheels 26. If the thickness of the metal sheet is less than the gap between the two pre - set guide wheels 26, then the metal sheet can smoothly pass through the gap in the middle of the guide wheels 26 without any obstruction. Immediately afterwards, it will naturally pass through the gap between the two roller shafts 27. However, when the thickness of the metal sheet is greater than the gap between the two guide wheels 26, the metal sheet will be in contact with the guide wheels 26, and during this continuous extrusion process, the connecting rod 24 will move under the precise rotation mechanism of the rotating shaft. As the connecting rod 24 moves, it will drive the movable block 22 to perform a corresponding displacement. This displacement causes the spring 28 and the hydraulic buffer rod 21 to be squeezed by the movable block 22. During this process, the hydraulic buffer rod 21 can effectively absorb and buffer part of the impact force. At the same time, when the movable block 22 moves, it will drive the two roller shafts 27 to move synchronously. This synchronous movement mechanism makes the distance between the two roller shafts 27 gradually increase, thus providing enough passing space for the thicker metal sheet. When the thicker metal sheet finally successfully passes through between the two roller shafts 27, since the thin sheet is no longer in contact with the guide wheels 26, the elastic potential energy stored in the spring 28 begins to be released at this time. This energy drives the movable block 22, the roller shafts 27, and the connecting rod 24 to quickly reset to the initial state, thereby greatly improving the efficiency and versatility of processing metal sheets with different thicknesses on the production line.

[0023] As Figures 1 to 5 shown, the number of the connecting rods 24 is set to four and evenly divided into two groups. Among them, two connecting rods 24 are distributed in an X - shape, and the movable blocks 22 are all slidably connected to the inner wall of the chute 11.

[0024] Adopting the above - mentioned solution: The two connecting rods 24 take the rotating rod 25 as the fixed point. When the guide wheel 26 is squeezed by the metal sheet, during this process, both ends of the connecting rod 24 move away from each other. Specifically, the extrusion force received by the guide wheel 26 is transmitted to the connecting rod 24, causing the connecting rod 24 to rotate around the rotating rod 25. Due to the connection method between the connecting rod 24 and the rotating rod 25 and the mechanical principle, this rotation causes the two ends of the connecting rod 24 to generate displacements away from each other. As the two ends of the connecting rod 24 move, they further exert an effect on the movable block 22, thereby causing the movable block 22 to squeeze the spring 28. During this process, the spring 28 undergoes elastic deformation under the pressure from the movable block 22.

[0025] As Figures 1 to 5 shown, the side of the connecting rod 24 away from the movable block 22 passes through the through - slot 12 and extends to the left of the limiting plate 23. It also includes two stabilizing plates 3 located in the middle of the two support plates 1.

[0026] Adopting the above solution: The connecting rod 24 is connected to the movable block 22 and extends to the left side surface of the movable block 22 through the through slot 12. The opening of the through slot 12 provides space for the movement of the connecting rod 24.

[0027] As Figures 1 to 5 shown, the number of roller shafts 27 is set to two, and equal gaps are left between the middle parts of the two roller shafts 27 and the middle parts of the two guide wheels 26.

[0028] The working principle and usage process of the present utility model:

[0029] First of all, when the metal thin plate is transported by this device, the metal thin plate will first come into contact with the guide wheel 26. If the thickness of the metal thin plate is less than the gap between the two pre-set guide wheels 26, then the metal thin plate can smoothly pass through the gap in the middle of the guide wheel 26 without any hindrance. Immediately afterwards, it will naturally pass through the gap between the two roller shafts 27. However, when the thickness of the metal thin plate is greater than the gap between the two guide wheels 26, the metal thin plate will be in contact with the guide wheel 26, and during this continuous extrusion process, the connecting rod 24 will move under the precise rotation mechanism of the rotating shaft. As the connecting rod 24 moves, it will drive the movable block 22 to perform corresponding displacement. This displacement will cause the spring 28 and the hydraulic buffer rod 21 to be squeezed by the movable block 22. During this process, the hydraulic buffer rod 21 can effectively absorb and buffer part of the impact force. At the same time, when the movable block 22 moves, it will drive the two roller shafts 27 to move synchronously. This synchronous movement mechanism makes the distance between the two roller shafts 27 gradually increase, thereby providing enough passing space for the thicker metal thin plate. When the thicker metal thin plate finally successfully passes through between the two roller shafts 27, since the thin plate is no longer in contact with the guide wheel 26, the elastic potential energy stored in the spring 28 begins to be released at this time. This energy drives the movable block 22, the roller shaft 27 and the connecting rod 24 to quickly reset to the initial state for subsequent use.
