Description

Technical Field

[0001] The utility model relates to the technical field of tableware production and processing, in particular to a polishing machine used for the production of stainless steel tableware. Background Art

[0002] Stainless steel tableware is an essential necessity in our daily life, and the manufacturing process of stainless steel tableware on the market, such as spoons and forks, includes punching, trimming, polishing, bending, hand throwing, and cleaning;

[0003] In the process of tableware production, a polishing machine is a machine that polishes the flat workpiece after punching through a polishing roller. The driving mechanism drives the polishing roller (for example, a brush or a grinding wheel) to rotate. The workpiece and the polishing roller generate friction, and the cutting force generated by the friction is used to grind the uneven parts of the workpiece surface flat, thereby removing scratches and burrs on the workpiece surface, making the workpiece surface bright, smooth, and presenting a mirror effect. In the prior art, the driving mechanism adopts a worm gear transmission, and the worm is the transmission shaft. The driving force of the motor is transmitted to the worm gear connected to the polishing roller. The upper roller and the lower roller are driven by gears to realize the rotation of the polishing roller. This transmission method has the following problems:

[0004] First, since the upper and lower rollers are driven by gears, the longitudinal positions of the upper and lower rollers cannot be moved, otherwise there will be gear interference or the gears will not be able to engage. Therefore, when the polishing roller is worn, the polishing roller cannot be radially adjusted to compensate. Secondly, since the polishing roller cannot be adjusted, the service life of the polishing roller is shortened, the replacement frequency of the polishing roller is increased, the downtime of the polishing machine is increased, the polishing process output is reduced, and the production cost is increased. Thirdly, the gear transmission and worm gear transmission have a complex structure. When wear occurs after use, in order to ensure the reliability of engagement, the drive mechanism needs to be replaced as a whole, which is time-consuming and labor-intensive, increases the cost of equipment use, and increases the difficulty of equipment maintenance.

[0005] Therefore, there is room for further improvement in the polishing machines for tableware production in the prior art. Utility Model Content

It will be understood that when used in this specification and the appended claims, the terms “comprises” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0033] It should be noted that the tableware mentioned in this application refers to stainless steel tableware with handles, namely stainless steel spoons and stainless steel forks, and the tableware is flat after the punching and trimming processes are completed.

[0034] Example 1: Figure 1-13As shown, a polishing machine for stainless steel tableware production includes a machine body 1, a polishing roller 2 rotatably assembled with the machine body 1, and a driving mechanism 3 assembled on the machine body 1 for driving the polishing roller 2. The polishing roller 2 includes an upper roller 201 and a lower roller 202. The upper roller 201 and the lower roller 202 are arranged opposite to each other to form a polishing channel 203. The machine body 1 is provided with a feed end and a discharge end, and the feed end and the discharge end are respectively arranged on both sides of the polishing channel 203. The driving mechanism 3 includes a rotating component 4 for rotating the polishing roller 2, an adjusting component 5 for adjusting the longitudinal distance of the polishing channel 203, and the rotating component 4 includes a sliding tensioning wheel 4. 01, sliding frame 402, motor 403, driving wheel 404, belt 405, connecting arm for connecting adjustment component 5 and sliding tensioning wheel 401, driven wheel 406 assembled with polishing roller 2, sliding frame 402 is assembled on machine body 1, sliding tensioning wheel 401 and sliding frame 402 are assembled for transverse sliding, both ends of motor 403 are respectively connected to machine body 7 and driving wheel 404, belt 405 is sleeved on the outer ring wall of driving wheel 404, the outer ring wall of sliding tensioning wheel 401, and the outer ring wall of driven wheel 406, when adjustment component 5 drives polishing roller 2 to move longitudinally, sliding tensioning wheel 401 slides transversely;

[0035] A further solution is that the driven wheel 406 of the upper roller 201 and the driven wheel 406 of the lower roller 202 are on the same longitudinal straight line, and the straight-line distance between the sliding tensioning wheel 401 and the driven wheel 406 of the upper roller 201 is equal to the straight-line distance between the sliding tensioning wheel 401 and the driven wheel 406 of the lower roller 202; the force arm between the upper roller and the sliding tensioning wheel is equal to the force arm between the lower roller and the sliding tensioning wheel, so that the force exerted by the upper roller on the sliding tensioning wheel through the connecting arm is equal to the force exerted by the lower roller on the sliding tensioning wheel through the connecting arm, thereby reducing the risk of the sliding tensioning wheel sliding and deflecting due to unbalanced force;

[0036] The adjusting assembly 5 includes a double-headed screw 501 and a slider. The body 1 is provided with a limiting frame 505 for the longitudinal sliding of the slider. The double-headed screw 501 and the limiting frame 505 can be rotatably assembled along the longitudinal axis. A right-handed threaded portion 5011 is provided above the polished rod of the double-headed screw 501, and a left-handed threaded portion 5012 is provided below the polished rod of the double-headed screw 501. The slider includes an upper slider 502 and a lower slider 503. The upper slider 502 is provided with an upper threaded hole adapted to the right-handed threaded portion 5011, and the lower slider 503 is provided with a lower threaded hole adapted to the left-handed threaded portion 5012. The upper slider 503 is threadedly connected to the right-handed threaded portion 5011, and the lower slider 503 is connected to the thread 5012 of the left-handed threaded portion. When the double-headed screw 501 is rotated clockwise, the upper slider 502 and the lower slider 503 simultaneously move along the axial direction of the double-headed screw 501 away from the polished rod of the double-headed screw 501;

[0037] Thus, it can be seen that by providing a double-headed screw, the polishing roller is adjusted longitudinally, so that the upper roller and the lower roller are simultaneously close to or away from each other, so that the polishing channel remains adapted to the tableware to be processed, thereby improving the quality of tableware polishing and improving the adaptability to tableware of different heights and sizes. Furthermore, when the polishing roller is worn, the polishing roller can be adjusted longitudinally to compensate for the radial wear of the polishing roller, thereby improving the utilization rate of the effective length of the polishing roller (for example, the length of the brush), but the usage amount needs to take into account the stainless steel tableware to ensure that the stainless steel tableware will not fall during polishing, thereby improving the service life of the polishing roller, reducing the replacement frequency of the polishing roller, reducing the downtime of the polishing machine, improving the polishing processing output, and reducing the polishing production cost;

[0038] By adopting a belt-driven rotating component, the polishing roller is driven to rotate, which simplifies the transmission structure of the polishing roller, reduces the difficulty of replacement, and reduces the cost of use and maintenance. In addition, by providing a sliding tensioner, when the adjusting component adjusts the longitudinal position of the polishing roller, the longitudinal displacement of the driven wheel of the upper roller and the driven wheel of the lower roller is converted into the lateral displacement of the sliding tensioner through the connecting arm. When the upper roller and the lower roller approach each other, the distance between the upper roller and the lower roller is reduced, so that the belt tends to relax. At this time, the sliding tensioner moves laterally away from the driven wheel along the sliding frame under the force of the connecting arm to tension the belt. Similarly, the driving reliability and stability of the driving component on the polishing roller are improved, the coordinated operation and linkage between the driving component and the adjusting component are improved, and the ingenuity of the drive mechanism design is improved.

[0039] Among them, the rotating component 4 also includes a connecting rod 407, the outer arm of the connecting rod 407 is fixedly connected to the inner wall of the driven wheel 106, one end of the connecting rod 407 is detachably assembled with the polishing roller 2, and the other end of the connecting rod 407 is rotatably assembled with the slider. A further solution is that the rotating component 4 also includes a bearing 408, and a bearing seat is provided at one end of the slider close to the polishing roller 2, and the bearing seat is recessed from the outside to the inside, and the outer ring of the bearing 408 is connected to the inner wall of the bearing seat, and the inner ring of the bearing 408 is connected to the outer wall of the connecting rod 407. It can be seen that by providing a connecting rod, the stability of the assembly of the polishing roller and the driving mechanism is improved, and by the detachable assembly of the polishing roller and the driving mechanism, the difficulty of replacing the polishing roller is reduced, the replacement efficiency of the polishing roller is improved, the time the polishing machine is shut down for replacement is reduced, and the processing and production output of the polishing machine is improved. When the polishing roller is exhausted, it is convenient to replace it. In addition, by providing a bearing, the smoothness of the rotation of the driven wheel and the slider is improved, the rotation resistance of the polishing roller is reduced, and the effectiveness of the motor work is improved.

[0040] Among them, the rotating component 4 also includes a rotating shaft 409, which is fixedly connected to the sliding tensioning wheel 401 and the axis of the rotating shaft 409 is arranged to coincide with the axis of the sliding tensioning wheel 401. The sliding frame 402 is provided with a horizontal long hole 4021, and the horizontal long hole 4021 is set to pass through from the outside to the inside. The rotating shaft 409 can be slidably assembled in the horizontal long hole 4021 and at least part of the rotating shaft 409 is exposed at the end face of the sliding frame 402; it can be seen that the sliding tensioning wheel 401 slides in the long hole 4021 through the rotating shaft 409. By providing the horizontal long hole, the rotation is limited, the position consistency of the horizontal sliding of the sliding tensioning wheel is improved, the risk of sliding deviation of the sliding tensioning wheel is reduced, the effectiveness and reliability of the sliding tensioning wheel for belt tensioning is improved, the stability of the driving mechanism for the polishing roller is improved, and the stability of the polishing machine processing is improved.

[0041] The connecting arm includes an upper connecting arm 410 and a lower connecting arm 411. The two ends of the upper connecting arm 410 are rotatably assembled to the connecting rod 407 and the rotating shaft 409 corresponding to the upper roller 201. The two ends of the lower connecting arm 411 are rotatably assembled to the connecting rod 407 and the rotating shaft 409 corresponding to the lower roller 202. The upper connecting arm 410 is arranged at the end of the lower connecting arm 411 away from the sliding frame 402.

[0042] Regarding the specific structure of the rotating assembly of the connecting arm and the polishing roller, refer to the attached Figure 12 , both ends of the connecting arm are connected with a rotating ring 412, which is sleeved on the outer ring wall of the polishing roller 2 and the outer ring wall of the rotating shaft 409 to achieve a rotating connection. Specifically, the rotating assembly method of the upper connecting arm 410 is further described. The rotating ring at one end of the upper connecting arm 410 is sleeved on the outer ring wall of the connecting rod 407, and the rotating ring at the other end of the upper connecting arm 410 is sleeved on the outer ring wall of the rotating shaft 409. In order to reduce the axial force of the upper connecting arm 410 The circumferential protrusion of the connecting rod 407 is provided with two sets of first shaft shoulders 413, and the two sets of first shaft shoulders 413 are respectively located on both sides of the axial direction of the rotating ring at one end of the upper connecting arm 410. The circumferential protrusion of the rotating shaft 409 is provided with two sets of second shaft shoulders 413, and the two sets of second shaft shoulders 413 are respectively located on both sides of the axial direction of the rotating ring at the other end of the upper connecting arm 410. The rotation assembly method of the lower connecting arm 411, the lower roller 202 and the rotating shaft 409 is similar, and will not be repeated here.

[0043] A further solution is that at least two groups of upper connecting arms 410 and lower connecting arms 411 are provided, the two groups of upper connecting arms 410 are provided on both sides of the axial direction of the sliding tensioning wheel 401, and the two groups of lower connecting arms 411 are provided on both sides of the axial direction of the sliding tensioning wheel 401 and are located at the end of the lower connecting arm 411 away from the sliding frame 402;

[0044] It can be seen from this that the consistency of the force exerted on the sliding tensioning wheel by the upper roller through the upper connecting arm and the lower roller through the lower connecting arm is improved, thereby improving the reliability of the driving mechanism operation. The two sets of connecting arms are arranged on both sides of the sliding tensioning wheel, so that the force of the sliding tensioning wheel is balanced, the output of the lateral sliding of the sliding tensioning wheel is improved, the risk of displacement due to inconsistent force is reduced, and the rationality of the mechanism design is improved.

[0045] The driving mechanism 3 includes a supporting assembly 6 for supporting the polishing roller 2, the rotating assembly 4 and the adjusting assembly 5 are arranged in the same direction and are located on one side of the axial direction of the polishing roller 2, and the supporting assembly 6 is arranged on the other side of the axial direction of the polishing roller 2;

[0046] Among them, the support assembly 6 includes a support column 601 and a slide. The slide is longitudinally provided with a through hole 6036. The inner wall of the through hole 603 is slidably connected to the outer wall of the support column 601. The slide is laterally provided with an assembly part 604 that can be detachably assembled with the polishing roller 2. The assembly part 604 is protruded from the slide toward the polishing roller 2. The slide includes an upper slide 6011 and a lower slide 6012. The upper slide 6011 is arranged corresponding to the upper roller 201, and the lower slide 6012 is arranged corresponding to the lower roller 202. It is worth mentioning that the assembly part 604 is a coupling well known to those skilled in the art.

[0047] It can be seen that by providing a support assembly to support the polishing roller, the two sides of the polishing roller are supported by force, the swing amount of the polishing roller when rotating is reduced, and the quality stability of the polishing roller for tableware polishing is improved. Furthermore, when the adjustment assembly longitudinally adjusts the slider through the double-headed screw, the slide moves longitudinally along the support column, and the support assembly plays a supporting and sliding role in the longitudinal adjustment of the polishing roller, thereby improving the reliability and stability of the longitudinal adjustment of the polishing roller.

[0048] The driving mechanism 3 further includes a coupling 301, and the coupling 301 is provided with multiple groups, wherein one group of couplings 301 is used to connect one end of the polishing roller 2 with the connecting rod 407, and another group of couplings 301 is used to connect the other end of the polishing roller 2 with the assembly portion 604;

[0049] It can be seen that the assembly part 604 is used to connect the transmission polishing roller 2. Those skilled in the art can know from the specific structure of the coupling 301 that the coupling 301 consists of two parts, one part of the coupling is connected to the shaft of the polishing roller 2, and the assembly part 604 should be the other part of the coupling. By providing a coupling, the convenience of disassembly and assembly of the polishing roller and the rotating assembly and the supporting assembly is improved, the difficulty of disassembly and assembly of the polishing roller is reduced, the efficiency of disassembly and assembly is improved, the stability of the rotation transmission of the polishing roller and the rotating assembly and the supporting assembly is improved, and the stability of the driving mechanism of the polishing roller is improved.

[0050] The feeding conveyor belt 101 is also included for feeding the tableware to be polished. The feeding conveyor belt 101 is arranged corresponding to the feeding end. The feeding conveyor belt 101 is arranged in the transverse direction of the polishing channel 203 and rotates in the direction of the polishing channel 203.

[0051] Among them, it also includes a discharge conveyor belt 102 for completing the discharge of polished tableware. The discharge conveyor belt 102 is set corresponding to the discharge end. The discharge conveyor belt 102 is set in the transverse direction of the polishing channel 203 and rotates away from the polishing channel 203. It can be seen that the degree of automation of tableware polishing feeding and discharging is improved, the work intensity of employees is reduced, the efficiency of tableware polishing feeding and discharging is improved, and the output of tableware polishing is increased.

[0052] It also includes guide rollers, and there are at least two groups of guide rollers. One group of guide rollers is arranged corresponding to the feed end and is located between one side of the polishing roller 2 and the feed conveyor belt 101, and the other group of guide rollers is arranged corresponding to the discharge end and is located between the other side of the polishing roller 2 and the discharge conveyor belt 102. The guide rollers include an upper guide roller 1031 and a lower guide roller 1032. The upper guide roller 1031 and the lower guide roller 1032 are arranged longitudinally and opposite to each other. It can be seen that by providing guide rollers, the tableware is supported and guided when entering or leaving the polishing channel, so as to facilitate the contact stability between the discharge conveyor belt and the tableware, and between the tableware and the feed conveyor belt, and play a connecting role, which is beneficial to the stability and reliability of the tableware feeding and discharging operation, and reduces the risk of tableware falling during feeding and discharging.

[0053] Among them, the polishing rollers 2 are provided with one or more groups. When multiple groups are provided, the polishing rollers 2 are arranged at equal intervals horizontally from the feed end to the discharge end. The driving mechanism 3 is provided corresponding to the polishing rollers 2 to improve the efficiency of tableware polishing, increase the contact area between the polishing rollers and the tableware, and improve the polishing quality of the tableware. The multiple groups of polishing rollers are controlled by a separate driving mechanism to improve the independence of the operation of the polishing rollers. When one of the polishing rollers has an abnormality, the impact on the other polishing rollers is reduced, which facilitates fault detection and elimination and reduces the difficulty of use and maintenance.

[0054] It is worth mentioning that when multiple groups of polishing rollers 2 are arranged at equal intervals, the distance between the centers of two adjacent groups of polishing rollers 2 is equal to the outer diameter of the polishing roller 2, thereby reducing the gap between the two adjacent groups of polishing rollers 2 and avoiding the risk of stainless steel tableware falling between the two adjacent groups of polishing rollers 2. The outer diameter of the polishing roller 2 is equal to the outer diameter of the guide roller, and the outer diameter of the polishing roller 2 is 1 / 3 to 1 / 4 of the length of the stainless steel tableware. It should be noted that the guide roller is a rubber roller, or is made of plastic steel.

[0055] Furthermore, in order to reduce the risk of stainless steel cutlery falling, refer to Figure 13The outer diameter of the polishing roller 2 is equal to the outer diameter of the guide roller and is 1 / 3 of the length of the stainless steel tableware. The upper guide roller 1031 and the lower guide roller 1032 are arranged up and down to form a guide roller group. There are N groups of guide roller groups. The upper roller 201 and the lower roller 202 are arranged up and down to form a polishing roller group. There are N-1 groups of polishing roller groups. The guide roller groups and the polishing roller groups are arranged alternately and equidistantly. The center distance between the two adjacent groups of upper rollers 201 and the upper guide roller 1031 is equal to the outer diameter of the polishing roller 2, and the center distance between the two adjacent groups of lower rollers 202 and the lower guide roller 1032 is equal to the outer diameter of the polishing roller 2. The belt surface of the feed conveyor belt 101 has a raised limit 1011. There are multiple groups of limit bars 1011 arranged at equal intervals perpendicular to the forward direction of the feed conveyor belt 101. A limit space 1012 is formed between the two adjacent groups of limit bars 1011. The width of the limit space 1012 is 1 / 2 of the width of the stainless steel tableware. .1~1.2 times. When polishing stainless steel, the operator places the stainless steel tableware in the limited space 1012, and the feed conveyor belt 101 rotates, driving the stainless tableware to move toward the guide roller group. Since the feed conveyor belt 101, the guide roller group, the polishing roller group, and the discharge conveyor belt 102 have the same rotation direction, the stainless steel tableware is driven by the first group of guide rollers to the first group of polishing rollers for polishing. Since the outer diameter of the polishing roller 2 is equal to the outer diameter of the guide roller and is 1 / 3 of the length of the stainless steel tableware, and during polishing, the polishing roller 2 will wear, but the guide roller will not wear, therefore, the outer diameter of the guide roller remains unchanged. When the stainless steel tableware is polished, it is clamped and guided by at least one group of guide rollers, thereby changing the travel path of the stainless steel tableware during polishing. After the polished stainless steel tableware passes through the last group of guide rollers, the stainless steel tableware contacts the discharge conveyor belt 102 for unloading and transportation.

[0056] The belt 405 is a synchronous belt, and the driving wheel 404, the driven wheel 406, and the sliding tensioning wheel 401 are adapted to the belt 405, thereby improving the stability and reliability of the driving mechanism for driving the polishing roller.

[0057] Among them, a rotation adjustment part 506 is provided at the upward end of the double-headed screw 501, and the rotation adjustment part 506 is exposed at the top of the limit frame 505. A further solution is that the rotation adjustment part 506 is hexagonal. By providing the rotation adjustment part, it is convenient to manually rotate the double-headed screw, thereby adjusting the longitudinal direction of the upper roller and the lower roller, and improving the rationality of the structural design. The rotation adjustment part is hexagonal, and the rotation adjustment can be performed using an open-end wrench tool, which reduces the difficulty of rotating the double-headed screw.

[0058] Among them, the adjustment component 3 also includes a manually adjustable tensioning wheel, which is detachably assembled with the sliding frame 402. The outer ring wall of the manually adjustable tensioning wheel is in contact with the belt 405 and is arranged between the driven wheel 406 and the sliding tensioning wheel 401, thereby improving the stability of the belt tensioning adjustment. When the belt is deformed during use, it can be manually adjusted to ensure that the belt is in a tensioned state during normal operation, thereby improving the reliability and stability of the driving mechanism operation.

[0059] Example 2: Figure 1-13 As shown, a synchronously adjustable dishwashing device includes a polishing machine for stainless steel tableware production in Example 1, further comprising a machine body 1, a polishing roller 2 rotatably assembled with the machine body 1, a driving mechanism 3 assembled on the machine body 1 for driving the polishing roller 2, a spraying mechanism 7 for spraying a cleaning liquid, and a synchronizing mechanism 8 for synchronizing and adjusting the spraying mechanism 7 and the driving mechanism 3. The spraying mechanism 7 is arranged above the polishing roller 2. The spraying mechanism 7 includes a liquid storage tank 701, a sleeve for conveying the cleaning liquid, and a water pump 702 for pumping the cleaning liquid from the liquid storage tank 701 into the sleeve. The axis of the sleeve is arranged parallel to the axis of the polishing roller 2 and is assembled with the machine body 1. The sleeve is provided with a spray hole facing the polishing roller 2, and the spray hole is arranged from the outside to the inside. The synchronizing mechanism 8 is connected to the sleeve.

[0060] It can be seen that during the tableware polishing process, the polishing roller polishes the surface of the tableware to generate metal dust. Driven by the circular rotation of the polishing roller, the metal dust rises or tends to rise. The spray mechanism is arranged above the polishing roller and the axis of the sleeve is arranged parallel to the axis of the polishing roller. The sleeve is provided with a spray hole facing the polishing roller. The cleaning liquid is sprayed downward from the spray hole along the axial direction of the sleeve. The suspended metal dust settles under the drive of the water flow, thereby improving the effectiveness of the dust removal of the spray mechanism, shortening the contact path between the cleaning liquid and the metal dust, reducing the amount of metal dust overflow, and reducing the impact of metal dust on the workshop environment. Secondly, the longitudinal height distance between the polishing roller and the sleeve is the same, which equalizes the spray pressure of the spray mechanism on the polishing channel, makes the water pressure in the polishing channel tend to be consistent, and improves the cleaning effect on the surface of the tableware. Thirdly, by providing a synchronization mechanism, the linkage between the polishing roller and the spray mechanism during longitudinal movement is improved, and the coordination of the cleaning device is improved.

[0061] The synchronization mechanism 8 includes a rack and a gear. The teeth of the gear are adapted to the teeth of the rack and the gear and the rack are meshed for transmission. The gear includes an upper gear 811, which is assembled at both ends of the sleeve. The rack includes an upper slider rack 801 and an upper slide rack 802. The upper slider rack 801 is fixedly connected to the upper slider 502 of the driving mechanism 3. The upper slider rack 801 is exposed on the limit frame 505 of the driving mechanism 3 and is close to the side of the polishing roller 2. The upper slide rack 802 is fixedly connected to the upper slide 6021 of the driving mechanism 3 and is set on the side close to the polishing roller 2.

[0062] Among them, the casing includes an outer steel pipe 703 and an inner steel pipe 704, the upper gear 811 is fixedly assembled with the outer steel pipe 703, the water suction end of the water pump 702 is connected to the liquid storage tank 701, and the water discharge end of the water pump 702 is connected to the inner steel pipe 704. The outer diameter of the inner steel pipe 704 is adapted to the inner diameter of the outer steel pipe 703 and the inner steel pipe 704 is sleeved in the outer steel pipe 703. The spray hole includes an outer hole 7031 and an inner hole 7041. The outer hole 7031 is set corresponding to the outer steel pipe 703, and the inner hole 7041 is set corresponding to the inner steel pipe 704. When the adjustment component 5 of the drive mechanism 3 is in the original position, the overlapping area of the inner hole 7041 and the outer hole 7031 is the largest. When the gear rotates, the overlapping area of the outer hole 7031 and the inner hole 7041 changes.

[0063] It can be seen that one end of the outer steel tube is connected to an upper gear that meshes with the upper slider rack for transmission, and the other end of the outer steel tube is connected to another upper gear that meshes with the upper slide rack for transmission. The two ends of the outer steel tube can be rotatably assembled on the machine body. When the polishing roller is adjusted longitudinally, the double-headed screw of the adjusting assembly rotates, driving the upper slider to move longitudinally, thereby causing the upper slider rack to move longitudinally. By rotating the upper gear meshed with the upper rack, the outer steel tube rotates, driving the other upper gear at the other end to rotate, causing the upper slide rack to move longitudinally, pushing the upper slide to move longitudinally along the support column, thereby driving the polishing roller to move longitudinally. The synchronization mechanism plays two roles. On the one hand, it plays a role in synchronous adjustment of the longitudinal adjustment of the polishing roller, and the linkage adjustment assembly The support assembly reduces the risk of the polishing roller tilting due to different longitudinal strokes on both sides, thereby improving the polishing quality of the polishing roller. On the other hand, the inner steel pipe is fixedly connected to the machine body. When the outer steel pipe rotates, the inner steel pipe does not rotate, resulting in a displacement difference between the outer and inner steel pipes, causing the overlapping area of the outer hole and the inner hole to change, so that the cleaning liquid in the inner steel pipe is sprayed out, causing the cross-sectional area to change. When the pump liquid pressure of the water pump is kept constant, the pressure of the cleaning liquid sprayed is controlled, reducing the workload of manual control and adjustment of the casing water pressure, improving the coordination and linkage between the spray mechanism and the polishing roller adjustment, improving the degree of automation of the cleaning device, and reducing the risk of misoperation or omission during manual operation.

[0064] Among them, the synchronization mechanism 8 also includes a synchronization rod 821, which is rotatably assembled with the body 1 and is located directly below the sleeve. The axis of the synchronization rod 821 is arranged parallel to the axis of the sleeve. The gear also includes a lower gear 812, which is fixedly assembled with both ends of the synchronization rod 821. The rack also includes a lower slider rack 803 and a lower slide seat rack 804. The lower slider rack 803 is fixedly connected to the lower slider 503 of the driving mechanism 3. The lower slider rack 803 is exposed on the limiting frame 505 of the driving mechanism 3 and is close to the side of the polishing roller 2. The lower slide seat rack 804 is fixedly connected to the lower slide seat 503 of the driving mechanism 3 and is arranged on the side close to the polishing roller 2.

[0065] The gear train is meshed with the gears of the lower slider and the gears of the lower slider are meshed together, and the gear train is meshed with the gears of the lower slider to move horizontally, thereby improving the polishing quality of the polishing roller.

[0066] The outer hole 7031 is in the shape of an elongated strip and is provided with a closing portion 7032. The closing portion 7032 is gradually contracted counterclockwise from the inner wall of the outer hole 7031 along the outer wall of the outer steel pipe 703. The radius of the closing portion 7032 is smaller than the radius of the outer hole.

[0067] It can be seen that by providing a long strip-shaped outer hole, when the outer steel pipe rotates, the outer hole rotates with the outer steel pipe, so that the overlapping area of the outer hole and the inner hole changes. The outer hole is provided with a gradually shrinking closing part, which improves the linearity of the change of the overlapping area of the outer hole and the inner hole, so that the linear change of the cleaning liquid spray pressure is achieved. When the polishing roller is in the original position, the distance between the sleeve and the polishing roller is the shortest, the distance is a, and the overlapping area of the outer hole and the inner hole is the largest. After the polishing roller has been used for a period of time, the radial direction of the polishing roller needs to be supplemented, the upper slider moves downward, and the outer steel pipe rotates counterclockwise toward the rack of the upper slider. At this time, the distance between the sleeve and the polishing roller is b, the distance b>the distance a, and the overlapping area of the outer hole and the inner hole is reduced. Therefore, the water pressure of the cleaning liquid sprayed out increases, and the spray distance of the cleaning liquid is increased to compensate for the change in the height difference between the sleeve and the polishing roller, so that the cleaning liquid in the sleeve is effectively sprayed toward the polishing roller, thereby improving the consistency of the cleaning effect and improving the coordination and linkage between the synchronization mechanism and the spraying mechanism.

[0068] Among them, the spray mechanism 7 also includes a liquid inlet steel pipe 705, which is connected to the water outlet end of the water pump 702 and one end of the inner steel pipe 704, and the outer wall of the liquid inlet steel pipe 705 is fixedly connected to the body 1. Among them, the spray mechanism 7 also includes a return steel pipe 706, which is connected to the other end of the inner steel pipe 704 and the pipe mouth of the return steel pipe 706 is set toward the liquid storage tank 701, and the outer wall of the return steel pipe 706 is fixedly connected to the body 1. The inner diameter of the return steel pipe 706 is smaller than the inner diameter of the liquid inlet steel pipe 705. It can be seen that by providing the liquid inlet steel pipe and the return steel pipe, the inner steel pipe is fixedly supported and limited, so that the inner steel pipe is guaranteed to be stable and not rotated, thereby improving the rationality and reliability of the structural design.

[0069] The spray mechanism 7 further includes a liquid receiving pan 707 fixedly connected to the body 1. The opening of the liquid receiving pan 707 is arranged toward the polishing roller 2 and is located between the polishing roller 2 and the synchronization rod 821. The bottom wall of the liquid receiving pan 707 is provided with a through drainage hole, which is connected to the liquid storage tank 701 by a pipe. This reduces the risk of contact between the synchronization rod and the cleaning liquid, protects the synchronization rod, separates the dry and wet areas of the cleaning device, improves the cleanliness of the cleaning device, and reduces the difficulty of maintenance and cleaning of the cleaning device.

[0070] The bottom wall of the liquid collecting pan 707 is gradually inclined toward the flared portion to improve the smoothness of the flow of the cleaning liquid. The spray mechanism 7 also includes a magnet sheet, a magnetic strip sheet 708 is arranged on the bottom wall of the liquid storage tank 701, and a magnet 708 is also arranged on the bottom wall of the liquid collecting pan 701. It can be seen that by providing a liquid collecting pan, the cleaning liquid flows through the polishing roller, washes away the polished metal dust, and flows down to the liquid collecting pan under the action of its own weight. The magnet sheet in the liquid collecting pan plays a first adsorption role on the metal dust, separating the metal dust in the cleaning liquid. The cleaning liquid enters the oil storage tank along the bottom wall of the liquid collecting pan through the drainage hole. The magnet sheet in the liquid storage tank plays a second adsorption role on the cleaning dust in the cleaning liquid, separating the metal dust in the cleaning liquid again, improving the cleanliness of the cleaning liquid, and improving the cleaning effect and quality of the spray mechanism.

[0071] Among them, the inner holes 7041 are provided with one or more groups. When multiple groups are provided, the inner holes 7041 are arranged in sequence and equidistantly along the axis of the inner steel pipe 704, and the outer holes 7031 are provided correspondingly to the inner holes 7041. Among them, the spray holes are provided with one or more groups. When multiple groups are provided, the spray holes are arranged in sequence and equidistantly along the axis of the sleeve. It can be seen that the spraying effect of the spray mechanism is improved, the uniformity of the spray mechanism spraying the polishing roller is improved, and the cleaning effect and cleaning quality stability of the cleaning device are improved.

[0072] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
