Description

Technical Field

[0001] The present invention relates to the technical field of electronic paper processing equipment, and in particular to an electronic paper side dirt removal mechanism with a replaceable brush head. Background Art

[0002] With the development of electronic technology, the concept of electronic paper (e-paper), also known as digital paper, has emerged. It is an ultra-thin, ultra-light display that can be understood as "paper-thin, flexible, and rewritable." E-paper has found widespread application in a variety of fields, including e-readers, electronic tags, and billboards. During the production process, especially after laser cutting, the edges of e-paper often retain dust particles and other stains. These stains not only affect the e-paper's aesthetics but can also adversely affect its subsequent performance.

[0003] Currently, there are many mechanisms on the market for removing stains from the edges of electronic paper. These mechanisms mainly remove stains through mechanical wiping, chemical cleaning, etc. However, these existing mechanisms still have some shortcomings in practical applications.

[0004] Specifically, existing electronic paper edge cleaning mechanisms typically employ either a fixed brush head or a semi-automatic, interchangeable brush head design. While the fixed brush head design is simple, it cannot be replaced promptly after a period of use, leading to a gradual decline in cleaning effectiveness and requiring shutdown and replacement of the entire mechanism, impacting production efficiency. While the semi-automatic brush head replacement design can improve replacement efficiency to a certain extent, it requires operator assistance, increasing labor costs and also carries the risk of reduced cleaning effectiveness due to untimely replacement. Therefore, a mechanism for electronic paper edge cleaning with an interchangeable brush head is proposed to address these technical issues. Summary of the Invention

[0005] The purpose of the present invention is to provide an electronic paper side cleaning mechanism with a replaceable brush head to address the deficiencies in the prior art, so as to solve the technical problem that the existing mechanism for cleaning the edge surface of electronic paper cannot automatically replace the brush head.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] An electronic paper side-edge decontamination mechanism with a replaceable brush head includes a base, on which are mounted an upper conveying component and a lower conveying component arranged side by side. The upper and lower conveying components cooperate to press and convey the electronic paper, forming a conveying track between the upper and lower conveying components. A left decontamination platform and a right decontamination platform are provided on the top of the base to respectively support the two sides of the electronic paper during conveyance. The left and right decontamination platforms are respectively placed on the left and right sides of the conveying track.

[0008] The base is provided with a support frame, the support frame is provided with a first slide rail arranged transversely and having a length direction perpendicular to the conveying direction of the electronic paper, the first slide rail is slidably provided with a first movable plate and a second movable plate respectively placed directly above the left and right decontamination platforms, the first movable plate is provided with a first lifting plate that can move up and down, and the second movable plate is provided with a second lifting plate that can move up and down; the base also includes a brush head component for wiping and decontaminating the edge surface of the electronic paper, the first lifting plate is provided with a first clamping drive mechanism for clamping and installing the brush head component and driving it to operate, and the second lifting plate is provided with a second clamping drive mechanism for clamping and installing the brush head component and driving it to operate;

[0009] The base is provided with a plurality of brush head placement platforms which are placed just below the first slide rail and are used to support spare brush head components. The plurality of brush head placement platforms are arranged in an equidistant array along the length direction of the first slide rail.

[0010] The beneficial effects of the present invention are as follows: after the electronic paper is conveyed to the initial ends of the upper conveying component and the lower conveying component, the middle position of the electronic paper is pressed by the upper conveying component and the lower conveying component, and the upper conveying component and the lower conveying component are operated while pressing, and the pressed electronic paper is conveyed to achieve pressed conveyance of the electronic paper. During the conveying process, the left and right sides of the electronic paper are respectively supported by the left and right decontamination platforms, and move on the top surfaces of the two.

[0011] In addition, under the action of the first clamping drive mechanism and the second clamping drive mechanism, brush head components are installed on the first lifting plate and the second lifting plate. When the upper conveying component and the lower conveying component press and convey the electronic paper, the left and right edges of the electronic paper move on the left and right dirt removal tables respectively. During the movement, the wiping parts of different brush head components contact the left and right edge surfaces (top surfaces) of the electronic paper respectively. At the same time, different brush head components are driven by the first clamping drive mechanism and the second clamping drive mechanism respectively to make the brush head components operate, thereby wiping and removing dirt from the electronic paper during the movement, thereby realizing automatic dirt removal processing.

[0012] When the brush head component needs to be replaced, by controlling the first lifting plate to move upward on the first movable plate and the second lifting plate to move upward on the second movable plate, the brush head components on both sides can be driven to move upward, and then the first movable plate and the second movable plate can be controlled to slide horizontally on the first slide rail, and the brush head component installed on the first lifting plate and the brush head component installed on the second lifting plate can also move horizontally, so as to move until the two brush head components are respectively placed above different brush head placement platforms, and then the first lifting plate and the second lifting plate are controlled to move downward, and the two brush head components are respectively placed on different brush head placement platforms, and the first clamping drive mechanism and the second clamping drive mechanism are operated to move the brush head components. Release, and after release, control the first lifting plate and the second lifting plate to move upward to realize the disassembly of the brush head component; after the brush head component that needs to be replaced is disassembled, control the first movable plate and the second movable plate to slide horizontally on the first slide rail again to move to just above the brush head placement table where the spare brush head component is placed, and control the first lifting plate and the second lifting plate to move downward a specified distance, and then operate the first clamping drive mechanism and the second clamping drive mechanism to clamp the brush head component; through the above operation, the automatic replacement of the brush head component is realized, and the decontamination mechanism is fully automated, without the need for additional operation by the staff, which greatly improves the surface treatment efficiency of the electronic paper and saves labor costs.

[0028] The following is a detailed description of an electronic paper side dirt removal mechanism with a replaceable brush head according to the present invention with reference to the accompanying drawings.

[0029] like Figure 1 As shown, an embodiment of an electronic paper side dirt removal mechanism with a replaceable brush head of the present invention includes a base 1, on which an upper conveying part 2 and a lower conveying part 3 arranged side by side are installed. The upper conveying part 2 and the lower conveying part 3 cooperate to press and convey the electronic paper. A conveying track is formed between the upper conveying part 2 and the lower conveying part 3. The initial end of the conveying track is connected to a feeding device (not shown in the figure) for feeding the electronic paper. The feeding device (not shown in the figure) intermittently conveys and feeds the electronic paper, so that after the electronic paper is conveyed to the initial ends of the upper conveying part 2 and the lower conveying part 3, the middle position of the electronic paper is pressed by the upper conveying part 2 and the lower conveying part 3. While pressing, the upper conveying part 2 and the lower conveying part 3 are operated to convey the pressed electronic paper, thereby realizing the press-conforming of the electronic paper. During the conveying process, the edge surface of the electronic paper can be cleaned.

[0030] In addition, a left-side decontamination platform 4 and a right-side decontamination platform 5 are provided on top of the base 1 to support the edges of the electronic paper during transport. The left-side decontamination platform 4 and the right-side decontamination platform 5 are placed on the left and right sides of the transport track, respectively. During the lamination and transport of the electronic paper by the upper and lower transport components 2 and 3, the left and right edges of the electronic paper are supported by the left and right decontamination platforms 4 and 5, respectively, and move on their top surfaces. Cleaning brushes 16 are provided on each of the left and right decontamination platforms 4 and 5 for cleaning the edges of the electronic paper. During the lamination and transport of the electronic paper, the edges of the electronic paper come into contact with the cleaning brushes 16, which remove particulate matter and stains.

[0031] However, in the process of pressing and conveying the electronic paper, in order to achieve the decontamination treatment of the left and right side surfaces of the electronic paper, a support frame 6 is installed on the base 1, and a first slide rail 7 is provided on the support frame 6, which is arranged horizontally and the length direction is perpendicular to the conveying direction of the electronic paper. The first slide rail 7 is slidably provided with a first movable plate 8 and a second movable plate 9 which are respectively placed directly above the left decontamination table 4 and the right decontamination table 5, and a first lifting plate 10 that can move up and down is provided on the first movable plate 8, and a second lifting plate 11 that can move up and down is provided on the second movable plate 9; by controlling the first movable plate 8 and the second movable plate 9 to slide horizontally on the first slide rail 7, the first lifting plate 10 and the second lifting plate 11 can also be moved horizontally, and the first lifting plate 10 can also be controlled to move up and down on the first movable plate 8, and the second lifting plate 11 can also be controlled to move up and down on the second movable plate 9. The cleaning mechanism also includes a brush head component 14 for wiping and cleaning the edge surface of the electronic paper. The first lifting plate 10 is equipped with a first clamping drive mechanism 12 for clamping and installing the brush head component 14 and driving it to operate. The second lifting plate 11 is equipped with a second clamping drive mechanism 13 for clamping and installing the brush head component 14 and driving it to operate. Under the action of the first clamping drive mechanism 12 and the second clamping drive mechanism 13, the brush head component 14 is installed on both the first lifting plate 10 and the second lifting plate 11. When the upper conveying part 2 and the lower conveying part 3 press and convey the electronic paper, the left and right edges of the electronic paper move on the left and right decontamination platforms 4 and 5 respectively. During the movement, the wiping parts of different brush head parts 14 contact the left and right edge surfaces (top surfaces) of the electronic paper respectively. At the same time, the first clamping drive mechanism 12 and the second clamping drive mechanism 13 drive the different brush head parts 14 respectively, so that the brush head parts 14 operate, thereby wiping and decontaminating the electronic paper during the movement, realizing automatic decontamination processing.

[0032] In addition, the base 1 is provided with a plurality of brush head placement platforms 15 placed directly below the first slide rail 7 and used to support spare brush head components 14. The plurality of brush head placement platforms 15 are arranged in an equidistant array along the length direction of the first slide rail 7; when the brush head component 14 has been used for a period of time, it needs to be replaced. By controlling the first lifting plate 10 to move upward on the first movable plate 8 and the second lifting plate 11 to move upward on the second movable plate 9, the brush head components 14 on both sides can be driven to move upward, and then the first movable plate 8 and the second movable plate 9 can be controlled to slide horizontally on the first slide rail 7, and the brush head component 14 installed on the first lifting plate 10 and the brush head component 14 installed on the second lifting plate 11 can also move horizontally, so as to move until the two brush head components 14 are respectively placed directly above different brush head placement platforms 15, and then the first lifting plate 10 and the second lifting plate 11 are controlled to move downward, and the two brush head components 1 4 are placed on different brush head placement platforms 15, and the first clamping drive mechanism 12 and the second clamping drive mechanism 13 are operated to loosen the brush head component 14. After loosening, the first lifting plate 10 and the second lifting plate 11 are controlled to move upward to realize the removal of the brush head component 14; after the brush head component 14 that needs to be replaced is removed, the first movable plate 8 and the second movable plate 9 are controlled to slide horizontally on the first slide rail 7 again to move to just above the brush head placement platform 15 where the spare brush head component 14 is placed, and the first lifting plate 10 and the second lifting plate 11 are controlled to move downward a specified distance, and then the first clamping drive mechanism 12 and the second clamping drive mechanism 13 are operated to clamp the brush head component 14; through the above operations, the automatic replacement process of the brush head component 14 is realized, and the decontamination mechanism is fully automated and does not require additional operation by the staff, which greatly improves the surface treatment efficiency of the electronic paper and saves labor costs.

[0033] like Figure 2 As shown, the upper conveying component 2 and the lower conveying component 3 have the same structure and are arranged in a mirror-image manner in their running directions, wherein the upper conveying component 2 includes a supporting cross bar 21, and sprockets 22 are rotatably provided at both ends of the supporting cross bar 21, a chain 23 is wound around the sprocket 22, and each chain plate of the chain 23 is equipped with a paper pressing component 24 for contacting the electronic paper to press the electronic paper; the lower conveying component 3 is also provided with a paper pressing component 24, and the moving direction of the paper pressing component 24 on the lower conveying component 3 is arranged in a mirror-image manner to the moving direction of the paper pressing component 24 on the upper conveying component 2, and the electronic paper is conveyed between the upper and lower arranged paper pressing components 24 to be pressed, and the electronic paper can be pressed and conveyed together with the driving sprocket 22.

[0034] like Figure 3As shown, the paper pressing member 24 includes a mounting member 241 fixed to the chain plate of the chain 23. A guide block 242 is provided on the side of the mounting member 241. It also includes a pressure plate 243 for contacting the surface of the electronic paper. A slider 244 is provided at the end of the pressure plate 243, which slides with the guide block 242 to move the pressure plate 243 toward or away from the chain 23. A first spring 245 is provided between the pressure plate 243 and the mounting member 241, which applies a force to the pressure plate 243 away from the chain 23. When the electronic paper is conveyed between the upper and lower paper pressing members 24, the first spring 245 compresses, applying force to the pressure plate 243, which compresses the electronic paper. The sprocket 22 then drives the chain 23 to move, achieving the conveying of the electronic paper. This pressed conveying method prevents the electronic paper from shifting during the wiping and cleaning process. Additionally, a layer of soft pad 246 is provided on the surface of the pressing plate 243 that contacts the electronic paper. The soft pad 246 prevents the electronic paper from being damaged when pressed.

[0035] like Figure 4 As shown, in order to control the first lifting plate 10 to automatically move up and down on the first movable plate 8, a plurality of vertically arranged slide bars 101 are installed on the first lifting plate 10, and the slide bars 101 are slid up and down on the first movable plate 8. A vertically arranged rack 102 is also installed on the first lifting plate 10, and a first servo motor 103 is installed on the first movable plate 8. A gear 104 for engaging with the rack 102 is provided on the output shaft of the first servo motor 103. The first servo motor 103 is operated to drive the gear 104 to rotate. Since the rack 102 is fixed, an upward pulling force or a downward pushing force is applied to the first lifting plate 10 through the rack 102, and the first lifting plate 10 automatically moves up and down on the first movable plate 8.

[0036] Furthermore, the first clamping drive mechanism 12 and the second clamping drive mechanism 13 have the same structure and operate in the same manner. The first clamping drive mechanism 12 installed on the first lifting plate 10 includes a transversely arranged second slide rail 121. The length direction of the second slide rail 121 is consistent with the conveying direction of the electronic paper. The second slide rail 121 is slidably provided with a first clamping portion 122 and a second clamping portion 123. The first clamping portion 122 and the second clamping portion 123 can slide in a direction close to or away from each other to clamp or release the brush head component 14. The first clamping portion 122 is provided with a first connecting plate 124. The second clamping portion 123 is provided with a second connecting plate 125. The first lifting plate 10 is rotatably provided with a first forward and reverse threaded rod 126 arranged transversely and having a length direction parallel to the length direction of the second slide rail 121. Different threaded portions on the first forward and reverse threaded rod 126 are respectively threadedly connected to the first connecting plate 124 and the second connecting plate 125. After the first forward and reverse threaded rod 126 is driven to rotate, the first connecting plate 124 and the second connecting plate 125 can be controlled to move closer to or farther away from each other, thereby driving the first clamping portion 122 and the second clamping portion 123 to slide on the second slide rail 121 in a direction toward or away from each other. The first lifting plate 10 is also equipped with a second servo motor 127. The output shaft of the second servo motor 127 is connected to one end of the first forward and reverse threaded rod 126 through a second transmission component 128. The second transmission component 128 can be a combination structure such as a transmission wheel and a transmission belt. When the second servo motor 127 is operated, the first forward and reverse threaded rod 126 can be driven to rotate under the transmission action of the second transmission component 128.

[0037] like Figure 5-8 As shown, the first clamping portion 122 and the second clamping portion 123 have the same structure and are arranged in a mirror image, wherein the first clamping portion 122 includes a support plate 1221 slidably arranged on the second slide rail 121, and the support plate 1221 is provided with a plurality of plug-in rods 1222 on one side close to the second clamping portion 123 for plugging with the brush head component 14 to fix it; how to achieve plug-in fixation is described below.

[0038] The brush head component 14 includes a supporting frame 141 and a cleaning cloth tape 144 for wiping and removing dirt from the electronic paper. A feeding roller 142 for continuously feeding out the cleaning cloth tape 144 and a receiving roller 143 for continuously receiving the cleaning cloth tape 144 are rotatably provided on the supporting frame 141. A pair of guide rollers 145 are also rotatably provided, which are respectively placed below the feeding roller 142 and the receiving roller 143. The fed cleaning cloth tape 144 is wound around the guide rollers 145 to stretch the cleaning cloth tape 144 so that the cleaning cloth tape 144 is arranged flatly to facilitate full contact with the edge surface of the electronic paper. A fixed frame 146 is provided on the left and right sides of the support frame 141. The fixed frame 146 is provided with a positioning sleeve 147 whose number is the same as the number of the plug-in rods 1222 and is used to insert the plug-in rods 1222; after controlling the first lifting plate 10 to move downward to a specified height and aligning the plug-in rods 1222 with the positioning sleeve 147, the first positive and negative screw rods 126 are driven to rotate, and the support plate 1221 moves with the plug-in rod 1222 in the direction close to the positioning sleeve 147 to plug the plug-in rod 1222 with the positioning sleeve 147, so as to realize the support frame 14 1 is fixedly mounted on the first lifting plate 10; with the cooperation of the up-and-down movement of the first lifting plate 10 and the lateral movement of the first movable plate 8, the cleaning cloth belt 144 wound around the guide roller 145 is driven to contact the edge surface of the electronic paper, pressing and conveying the electronic paper while driving the unwinding roller 142 and the receiving roller 143 to rotate simultaneously in the same direction. The cleaning cloth belt 144 moves to wipe and remove dirt from the edge surface of the electronic paper; the edge of the electronic paper is the part that has been laser cut, and dust particles and other stains may remain in this part, which can be erased by wiping in the direction of the direction.

[0039] Additionally, a first bevel 148 is formed at the inner edge of the opening of each positioning sleeve 147 . With the action of the first bevel 148 , the connecting rod 1222 can be accurately inserted into the positioning sleeve 147 .

[0040] Furthermore, the unloading roller 142 and the receiving roller 143 are detachably provided on the support frame 141. Specifically, a first sliding plate 149 is slidably provided in the fixed frame 146 on the left, and a second sliding plate 1410 is slidably provided in the fixed frame 146 on the right, and a second positive and negative screw rod 1411 is rotatably provided on the fixed frame 146, and the length direction of the second positive and negative screw rod 1411 is consistent with the sliding direction of the first sliding plate 149 or the sliding direction of the second sliding plate 1410. The different threaded parts on the second positive and negative screw rod 1411 are respectively threadedly connected to the first sliding plate 149 and the second sliding plate 1410 to drive the first sliding plate 149 and the second sliding plate 1410 to move towards or away from each other. A knob 1412 is installed on the end of the second positive and negative screw rod 1411. The staff can rotate the second positive and negative screw rod 1411 by rotating the knob 1412.

[0041] In addition, a pair of third rotating shafts 1413 are rotatably provided on the first sliding plate 149 and the second sliding plate 1410, and the third rotating shafts 1413 are respectively coaxially arranged with the discharge roller 142 and the receiving roller 143, and first slots 1415 for inserting the ends of the third rotating shafts 1413 are formed on the left and right end surfaces of the discharge roller 142 and the receiving roller 143, and a plurality of first splicing grooves 1416 are formed on the inner side walls of each first slot 1415, and a second protrusion 1414 for embedding in the first splicing groove 1416 is provided on the end of each third rotating shaft 1413 inserted into the first slot 1415. By inserting the end of the third rotating shaft 1413 on the first sliding plate 149 and the end of the third rotating shaft 1413 on the second sliding plate 1410 into the first slots 1415 on the left and right sides of the unloading roller 142 and the left and right sides of the receiving roller 143, respectively, different second protrusions 1414 are embedded in the corresponding first splicing grooves 1416, so that the third rotating shaft 1413 on the first sliding plate 149 and the third rotating shaft 1413 on the second sliding plate 1410 are spliced ​​with the unloading roller 142 and the receiving roller 143 respectively. When the plurality of third rotating shafts 1413 are driven to rotate synchronously in the same direction, the unloading roller 142 and the receiving roller 143 can be driven. The rollers 143 rotate synchronously in the same direction to realize the unloading and retrieving of the cleaning cloth tape 144; in addition, by rotating the knob 1412 to rotate the second forward and reverse screw rod 1411, the first sliding plate 149 and the second sliding plate 1410 are controlled to move in the direction away from each other, and the first sliding plate 149 and the second sliding plate 1410 are separated from the unloading roller 142 and the retrieving roller 143 with the third rotating shaft 1413, thereby realizing the replacement of the unloading roller 142 and the retrieving roller 143, and replacing the new unloading roller 142, the retrieving roller 143 and the cleaning cloth tape 144, and placing them on the brush head placement table 15 for standby.

[0042] However, in order to drive the plurality of third rotating shafts 1413 to rotate synchronously in the same direction, the first clamping portion 122 also includes a driving component for driving the third rotating shaft 1413 on the first sliding plate 149 to rotate. The structure of the first clamping portion 122 is the same as that of the second clamping portion 123, so the second clamping portion 123 also includes a driving component, and the driving component is used to drive the third rotating shaft 1413 on the second sliding plate 1410 to rotate; when the connecting rod 1222 is plugged into the positioning sleeve 147, the driving component of the first clamping portion 122 is plugged into the third rotating shaft 1413 on the first sliding plate 149, and the driving component of the second clamping portion 123 is plugged into the third rotating shaft 1413 on the second sliding plate 1410. By operating the driving components on both sides at the same time, the plurality of third rotating shafts 1413 can be driven to rotate synchronously in the same direction.

[0043] Specifically, a splicing kit 1417 is provided on the end of each third rotating shaft 1413 away from the second protrusion 1414, and the driving component of the first clamping part 122 includes a first rotating shaft 1223 and a second rotating shaft 1224 which are rotatably set on the support plate 1221 and are coaxially arranged with the discharge roller 142 and the receiving roller 143 respectively. The ends of the first rotating shaft 1223 and the second rotating shaft 1224 are both equipped with connecting blocks 12210 for connecting with the splicing kit 1417, and the inner side wall of the splicing kit 1417 is formed with a plurality of second splicing grooves 1418, and the circumference of the connecting block 12210 is formed with a plurality of first protrusions 12214 which are respectively embedded in different second splicing grooves 1418. Under the plug-in action of the connecting block 12210 and the splicing kit 1417, the first rotating shaft 1223 and the second rotating shaft 1224 are respectively plugged into different third rotating shafts 1413 on the first sliding plate 149. When the first rotating shaft 1223 and the second rotating shaft 1224 are driven to rotate synchronously in the same direction, multiple third rotating shafts 1413 are driven to rotate synchronously in the same direction.

[0044] A transmission gear 1225 is provided on the ends of the first rotating shaft 1223 and the second rotating shaft 1224 away from the connecting block 12210. A transmission belt 1226 is wound around the transmission gear 1225. The driving component of the first clamping portion 122 also includes a driving motor 1227 mounted on the support plate 1221. The output shaft of the driving motor 1227 is connected to the end of the second rotating shaft 1224 or the end of the first rotating shaft 1223 through a first transmission component 1228. The first transmission component 1228 can be composed of a pair of mutually meshing bevel gears. When the driving motor 1227 is operated, the second rotating shaft 1224 or the first rotating shaft 1223 can be driven to rotate under the transmission action of the first transmission component 1228. Moreover, under the transmission action of the transmission belt 1226 and the transmission gear 1225, the second rotating shaft 1224 and the first rotating shaft 1223 rotate synchronously in the same direction.

[0045] In this embodiment, when the plug-in rod 1222 is plugged into the positioning sleeve 147, the connecting block 12210 is also plugged into the splicing kit 1417. However, during the plug-in process, the first protrusion 12214 on the connecting block 12210 may not be aligned with the second splicing groove 1418 and cannot be inserted. In order to solve this problem, the first rotating shaft 1223 and the second rotating shaft 1224 are both equipped with a buffer component 1229 that enables the connecting block 12210 to be moved. During the plug-in process, if the first protrusion 12214 is not aligned with the second splicing groove 1418 and the support plate 1221 continues to move, the connecting block 1221 After contacting the splicing kit 1417, the connecting block 12210 moves on the first rotating shaft 1223 and the second rotating shaft 1224 through the buffer component 1229, and applies a thrust to the connecting block 12210. However, the first rotating shaft 1223 and the second rotating shaft 1224 are driven to rotate, and the connecting block 12210 is driven to rotate at the same time. After the first protrusion 12214 is aligned with the second splicing groove 1418, the buffer component 1229 applies a thrust to the connecting block 12210, so that the connecting block 12210 and the positioning sleeve 147 are automatically plugged in, and the first protrusion 12214 is automatically embedded in the second splicing groove 1418, achieving an adaptive effect.

[0046] like Figure 9As shown, the buffer component 1229 includes a fixed block 12291 fixedly set on the first rotating shaft 1223 (or the second rotating shaft 1224), a sliding chamber 12292 is formed in the fixed block 12291, and a plurality of guide columns 12293 whose length direction is parallel to the axis of the first rotating shaft 1223 are provided in the sliding chamber 12292, and a sliding member 12294 is slidably provided on the guide column 12293, and also includes a connecting rod 12295 coaxially arranged with the first rotating shaft 1223, one end of the connecting rod 12295 is fixed to the connecting block 12210, and the other end passes through the fixed block 12291 and is fixed to the sliding member 12294; the sliding member 12294 slides in the fixed block 12291, so that the connecting block 12210 can move along its axial direction on the first rotating shaft 1223 (or the second rotating shaft 1224), thereby buffering the position of the connecting block 12210. In addition, after buffering, in order to apply thrust to the connecting block 12210 , a third spring 12296 is provided on each guide column 12293 , and the third spring 12296 is placed on the side of the sliding member 12294 away from the connecting block 12210 to apply thrust to the sliding member 12294 . When the first protrusion 12214 is not aligned with the second splicing groove 1418, the first protrusion 12214 is blocked by the splicing kit 1417. At this time, the support plate 1221 continues to move with the first rotating shaft 1223 and the second rotating shaft 1224, and the sliding member 12294 slides in the fixed block 12291. The third spring 12296 is compressed. When the first rotating shaft 1223 and the second rotating shaft 1224 drive the connecting block 12210 to rotate until the first protrusion 12214 is aligned with the second splicing groove 1418, under the action of the compressed third spring 12296, the connecting block 12210 is pushed, so that the connecting block 12210 is automatically plugged into the positioning sleeve 147.

[0047] Additionally, both the first clamping portion 122 and the second clamping portion 123 are provided with a positioning component, comprising a positioning block 12211 disposed on the same side as the plug-in rod 1222, and a guide rod 12212 fixedly disposed on the positioning block 12211. The guide rod 12212 is slidably disposed on the support plate 1221, and its sliding direction is parallel to the length direction of the second slide rail 121. The guide rod 12212 is provided with a second spring 12213, which is disposed between the support plate 1221 and the positioning block 12211 to apply force to the positioning block 12211. When a force is applied to the positioning block 12211 toward the support plate 1221, the guide rod 12212 moves on the support plate 1221, compressing the second spring 12213. When the force applied to the positioning block 12211 is stopped, the positioning block 12211 automatically returns to its original position due to the compression of the second spring 12213.

[0048] In addition, positioning rails 1419 are provided on the fixed frames 146 on the left and right sides. The positioning rails 1419 are formed with vertically arranged guide grooves 1420 for the positioning blocks 12211 to be inserted into. The top opening of the guide grooves 1420 is provided with a second bevel 1421 for facilitating the insertion of the positioning blocks 12211. When the brush head component 14 needs to be clamped and fixed, the first lifting plate 10 is controlled to move downward. During the movement, the positioning blocks 12211 are first inserted into the guide grooves 1420. However, if the positioning blocks 12211 are not inserted into the guide grooves 1420, it means that the brush head component 14 placed on the brush head placement platform 15 is not properly positioned, making it impossible for the connecting rod 1222 to align with the positioning sleeve 147. By providing the positioning blocks 12211 and the positioning rails 1419, the installation accuracy when replacing the brush head component 14 is further improved. If the positioning block 12211 is embedded in the guide groove 1420, it means that the brush head component 14 is in the specified installation position. The first lifting plate 10 moves downward until the connecting rod 1222 is aligned with the positioning sleeve 147, and then the support plate 1221 is controlled to move so that the connecting rod 1222 is plugged into the positioning sleeve 147. The positioning block 12211 moves on the support plate 1221 through the guide rod 12212.

[0049] like Figure 10 As shown, the brush head placement platform 15 is formed with a support 153 for supporting the support frame 141, and is also formed with a plurality of embedded grooves 152 placed above the support 153. The side of the support frame 141 is provided with a plurality of embedded blocks 151 (such as Figure 6 As shown), after the support frame 141 is placed on the support platform 153 of the brush head placement table 15, the embedded block 151 on the support frame 141 is embedded in the embedded groove 152, so that the support frame 141 is always placed at the specified position on the brush head placement table 15, which is convenient for accurate replacement of the brush head component 14 and avoids errors when disassembling and installing the brush head component 14.

[0050] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.
