Description

Technical Field

[0001] The invention relates to the technical field of steel strip surface roughening treatment, and in particular to an endless steel strip surface roughening treatment device. Background Art

[0002] The endless steel belt needs to be coated in the subsequent process. In order to increase the adhesion between the coating and the steel belt, the surface of the steel belt needs to be roughened. The conventional roughening method generally adopts sandblasting. However, since the thickness of the steel belt is too thin, sandblasting will cause the steel belt to deform, causing the surface of the steel belt to become uneven, and thus it cannot be used normally as a conveyor steel belt;

[0003] In order to solve the problem of deformation caused by sandblasting, there is a device in the prior art that uses a sand belt to roughen and grind the surface of a steel belt, which is also called a sand belt grinder. A sand belt grinder is a commonly used polishing and grinding device in mechanical processing. The sand belt grinding device drives the sand belt on it to run in a straight line through the rotation of the active sand belt wheel and the driven sand belt wheel to polish and grind the workpiece;

[0004] The distance between the active belt wheel and the driven belt wheel of the existing belt grinding device is fixed, and the belt runs tautly on the active belt wheel and the driven belt wheel. When the belt is replaced, it is difficult to remove or install the belt from the active belt wheel and the driven belt wheel. Summary of the invention

[0005] In order to solve the above technical problems, an endless steel belt surface roughening treatment device is provided, which solves the problem of inconvenient removal and replacement of the abrasive belt in the abrasive belt grinder in the prior art.

[0010] Preferably, a first through groove is formed through the inner wall of the lifting frame, and a second through groove is formed through the inner wall of the mounting frame. Both ends of the transmission screw rod penetrate through the first and second through grooves respectively. A nut seat is threadedly sleeved on the rod body of the transmission screw rod located in the first through groove, and a bearing seat is rotatably sleeved on the rod body of the transmission screw rod located in the second through groove.

A first bellows is arranged between the connecting plate and the lifting frame, and a second bellows is fixed between the lifting frame and the mounting frame. Both the first bellows and the second bellows wrap the transmission screw rod. A rotating groove is also formed through the inner wall of the lifting frame. A fixing frame perpendicular to the mounting frame is erected in the rotating groove, and the end of the fixing frame is fixedly connected to the connecting plate through a bracket.

[0012] Preferably, the lubricating component includes an annular oil storage seat fixed between the end of the first bellows and the lifting frame. The outer peripheral surface of the annular oil storage seat is open, and an airbag skin is fixed in the open part. A plurality of nozzles are arranged around the inner peripheral surface of the annular oil storage seat, and the ends of the nozzles face the transmission screw rod. A tightening member is arranged on the periphery of the airbag skin.

[0013] Preferably, an oil injection bottle is fixedly communicated with the top of the annular oil storage seat. A plug is inserted into the top end of the oil injection bottle, and one-way valves are arranged inside the bottom end of the oil injection bottle and inside the nozzles respectively.

[0014] Preferably, the tightening member includes a pressing strip wound on the outer wall of the airbag skin.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] (1) Through the setting of the lifting part, the knob drives the screw and the nut seat can slide linearly along the shaft of the drive screw under the threaded structure, driving the lifting frame and the second drive roller to move synchronously as a whole, thereby reducing the distance between the second drive roller and the first drive roller, making the sanding belt no longer tight, and facilitating quick manual replacement.

[0020] (2) By setting up the sealing component, during the descending process of the lifting frame, the lifting frame can stretch the bellows one while compressing the bellows two, so that the bellows one cooperates with the bellows two to cover and envelop the transmission screw in real time, thereby providing a relatively good sealing environment for the transmission screw and reducing the influence of debris and impurities on the transmission screw.

[0021] (3) Through the setting of the lubrication component, when the lifting frame carrying the second transmission roller is rapidly lowered by utilizing the driving screw, the tightening component will simultaneously contract and compress the airbag skin, squeezing the lubricating oil stored in the annular oil storage seat, so that the lubricating oil is output from the nozzle to the driving screw, causing the lubricating oil to spray on the driving screw shaft and slide into the gap between the driving screw and the nut seat, thereby automatically realizing the lubrication operation of the driving screw and the nut seat, without the need for manual subsequent tedious disassembly of the bellows 1 and bellows 2 for re-lubrication, thereby improving the operation efficiency and enhancing the practicality.

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] Reference Figures 1-5 As shown, an endless steel belt surface roughening treatment device includes a roller conveyor 1 and a roughening treatment mechanism located at one end of the roller conveyor 1;

[0031] The roughening treatment mechanism includes a mounting base plate 2 which is linearly movable above the roller conveyor 1, and a first transmission roller 5 and a second transmission roller 6 are rotatably provided at the upper and lower ends of one side of the mounting base plate 2, and an abrasive belt 7 is transmission-connected between the first transmission roller 5 and the second transmission roller 6;

[0032] A motor 8 is installed at the bottom end of the other side of the mounting base plate 2, and the output shaft of the motor 8 rotates through the mounting base plate 2 and is fixedly connected to one end of the first transmission roller 5;

[0033] A cylinder 4 is installed on one side wall of the roller conveyor 1, and a mounting seat 3 is fixed between the telescopic end of the cylinder 4 and the top of the mounting base plate 2;

[0034] Through the arrangement of the first transmission roller 5, the second transmission roller 6 and the abrasive belt 7, when the roller conveyor 1 is used to transport the steel belt, the cylinder 4 is turned on to cause the mounting base plate 2, the first transmission roller 5, the second transmission roller 6 and the abrasive belt 7 to move downward linearly as a whole, so that the abrasive belt 7 contacts the surface of the steel belt, and then the motor 8 is turned on to rotate the first transmission roller 5, and then the abrasive belt 7 is quickly rotated, so that the abrasive belt 7 can effectively grind different positions of the surface of the steel belt during the transportation process.

[0035] Further, refer to Figure 3 As shown, it is worth noting that a lifting part for adjusting the distance between the first transmission roller 5 and the second transmission roller 6 is provided on the inner side of the abrasive belt 7;

[0036] The lifting part includes a lifting frame 9 that slides on one side of the mounting base plate 2 through a slider and a slide groove, one end of the second transmission roller 6 is vertically rotatably connected to the inner wall of the lifting frame 9, a mounting frame 10 vertically fixed to the mounting base plate 2 is arranged below the lifting frame 9, and a transmission screw 11 is vertically arranged between the lifting frame 9 and the mounting frame 10;

[0037] A through slot one is penetrated and formed in the inner wall of the lifting frame 9, and a through slot two is penetrated and formed in the inner wall of the mounting frame 10. Both ends of the transmission screw rod 11 penetrate through the through slot one and two respectively. And a nut seat 12 is threadedly sleeved on the rod body of the transmission screw rod 11 located in the through slot one, and a bearing seat 13 is rotatably sleeved on the rod body of the transmission screw rod 11 located in the through slot two. Both the bearing seat 13 and the nut seat 12 are fixedly connected to the inner walls of the through slot one and two respectively through brackets;

[0038] Through the setting of the lifting part, when the knob drives the transmission screw rod 11, the nut seat 12 can linearly slide along the rod body of the transmission screw rod 11 under the thread structure, driving the entire lifting frame 9 and the second transmission roller 6 to displace synchronously, thereby reducing the distance between the second transmission roller 6 and the first transmission roller 5, making the sand belt 7 no longer taut and facilitating quick replacement by the operator.

[0039] In the above-mentioned embodiment, although the distance between the second transmission roller 6 and the first transmission roller 5 can be quickly adjusted through the setting of the transmission screw rod 11, in reality, during the sanding process of the sand belt 7, a large amount of impurities and debris are easily attached to the rod body of the transmission screw rod 11. The presence of impurities easily affects the thread transmission effect of the nut seat 12, resulting in jamming or accelerated wear;

[0040] Therefore, referring to Figure 3 and Figure 4 as shown, it is worth noting that there is also a protection part for extending the service life of the lifting part;

[0041] The protection part is composed of a sealing component and a lubricating component;

[0042] Among them, the sealing component includes a connecting plate 16 arranged above the transmission screw rod 11. A corrugated pipe one 17 is arranged between the connecting plate 16 and the lifting frame 9, and a corrugated pipe two 18 is fixed between the lifting frame 9 and the mounting frame 10. Both the corrugated pipe one 17 and the corrugated pipe two 18 wrap the transmission screw rod 11. A rotating slot is also penetrated and formed in the inner wall of the lifting frame 9. A fixing frame 25 perpendicular to the mounting frame 10 is erected in the rotating slot, and the end of the fixing frame 25 is fixedly connected to the connecting plate 16 through a bracket;

[0043] Through the setting of the sealing component, during the downward movement of the lifting frame 9, the lifting frame 9 can stretch the corrugated pipe one 17 while compressing the corrugated pipe two 18. In this way, the corrugated pipe one 17 cooperates with the corrugated pipe two 18 to continuously shield and cover the transmission screw rod 11 in real time, providing a relatively good sealing environment for the transmission screw rod 11 and reducing the influence of debris and impurities on the transmission screw rod 11.

[0044] Furthermore, referring to Figures 3-5As shown, it is worth noting that the lubrication assembly includes an annular oil storage seat 19 fixed between the end of the first bellows 17 and the lifting frame 9. The outer peripheral surface of the annular oil storage seat 19 is open, and an airbag skin 20 is fixed in the opening. A number of nozzles 21 are arranged around the inner peripheral surface of the annular oil storage seat 19, and the ends of the nozzles 21 face the transmission screw 11. A tightening member is arranged around the airbag skin 20;

[0045] The top of the annular oil storage seat 19 is fixedly connected to an oil injection bottle 22. A plug is inserted at the top of the oil injection bottle 22, and check valves are arranged inside the bottom end of the oil injection bottle 22 and inside the nozzles 21;

[0046] Through the setting of the lubrication assembly, when the lifting frame 9 driven by the transmission screw 11 quickly slides down with the second transmission roller 6, the tightening assembly synchronously contracts to compress the airbag skin 20, squeezing the lubricating oil stored in the annular oil storage seat 19, opening the check valve inside the nozzle 21, so that the lubricating oil is output from the nozzle 21 and aligned with the transmission screw 11, causing the lubricating oil to spray on the rod body of the transmission screw 11 and slide into the gap between the transmission screw 11 and the nut seat 12. In this way, the lubrication operation of the transmission screw 11 and the nut seat 12 is automatically realized, without the need for subsequent cumbersome manual disassembly of the first bellows 17 and the second bellows 18 for lubrication, improving the operation efficiency and enhancing the practicability;

[0047] Conversely, when the lifting frame 9 drives the second transmission roller 6 to move upward, similarly, the tightening assembly reduces the pressure on the airbag skin 20, and the airbag skin 20 can reset under its own elasticity, so that the check valve inside the oil injection bottle 22 is opened, and the lubricating oil is quickly replenished into the annular oil storage seat 19.

[0048] Furthermore, referring to Figure 3 and Figure 4 As shown, it is worth noting that the tightening member includes a pressing strip 23 wound around the outer wall of the airbag skin 20. A winding cylinder 24 rotatably connected to the inner wall of the rotating groove is sleeved on the rod body of the fixed frame 25. One end of the pressing strip 23 is fixedly connected to the inner wall of the annular oil storage seat 19, and the other end of the pressing strip 23 is fixedly connected to the barrel wall of the winding cylinder 24;

[0049] An external thread block 26 is tightly sleeved on the rod body of the fixed frame 25, and the external thread block 26 is threadedly connected to the inner wall of the winding cylinder 24;

[0050] When the lifting frame 9 moves downward, the winding cylinder 24 can slide down along the rod body of the fixed frame 25 synchronously. In this way, the winding cylinder 24 rotates under the thread structure and pulls one end of the pressing strip 23, so that the pressing strip 23 tightens and compresses the airbag skin 20;

[0051] Conversely, when the lifting frame 9 moves upward, the winding cylinder 24 reverses under the thread structure, loosening the pull on one end of the pressing strip 23, and thus reducing the pressing effect on the airbag skin 20.

[0052] Further, with reference to Figure 3 As shown, it is worth noting that an installation cylinder 14 communicating with the second through groove is fixed at the bottom end of the mounting bracket 10. A worm 15 is rotatably penetrated through the inner wall of the installation cylinder 14. A worm wheel meshing with the worm 15 is tightly sleeved on the rod body of the transmission screw 11;

[0053] Turn the worm 15, causing the worm 15 to mesh with the worm wheel, so that the transmission screw 11 can be effectively rotated and a rotational force is provided for the transmission screw 11.

[0054] Further, with reference to Figure 3 As shown, it is worth noting that a winding drum 27 is threadedly connected to the outer wall of the installation cylinder 14;

[0055] Through the arrangement of the winding drum 27, the lubricating oil dripping along the rod body of the transmission screw 11 can be effectively received at the bottom end of the mounting bracket 10, so as to realize the reuse of the lubricating oil and reduce material waste.

[0056] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
