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, people have proposed the concept of electronic paper, also known as digital paper. It is an ultra-thin and ultra-light display screen, which can be understood as "a display that is as thin as paper, soft, and rewritable". Electronic paper has been widely used in many fields such as e-readers, electronic tags, and billboards. During the production process of electronic paper, especially after laser cutting, dust particles and other stains often remain on its edges. These stains not only affect the aesthetics of the electronic paper, but may also have an adverse effect on its subsequent performance.

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

[0004] Specifically, existing electronic paper edge decontamination mechanisms usually adopt a fixed brush head or a semi-automatic brush head replacement design. Although the fixed brush head design is simple in structure, the brush head cannot be replaced in time after being used for a period of time, resulting in a gradual decrease in the decontamination effect. The entire mechanism needs to be stopped and replaced, affecting production efficiency; and the semi-automatic brush head replacement design can solve the replacement efficiency to a certain extent, but requires staff to assist in the operation, increasing labor costs, and there is also a risk of reduced decontamination effect due to untimely replacement. Therefore, an electronic paper side decontamination mechanism with a replaceable brush head is provided to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide an electronic paper side dirt removal mechanism with a replaceable brush head in view of the deficiencies in the prior art, so as to solve the technical problem that the existing mechanism for cleaning the side surface of electronic paper cannot realize automatic replacement of the brush head.

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

[0007] An electronic paper side dirt removal mechanism with a replaceable brush head comprises a base, an upper conveying component and a lower conveying component arranged side by side are mounted on the base, the upper conveying component and the lower conveying component cooperate to press and convey the electronic paper, and a conveying track is formed between the upper conveying component and the lower conveying component; a left dirt removal platform and a right dirt removal platform are respectively provided on the top of the base for supporting the two sides of the electronic paper during the conveying process, and the left dirt removal platform and the right dirt removal platform are respectively placed on the left and right sides of the conveying track;

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

[0009] The base is provided with a plurality of brush head placement tables which are placed directly below the first slide rail and are used to support spare brush head components. The plurality of brush head placement tables 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 dirt removal platform and the right dirt removal platform, 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 decontaminating the electronic paper in the movement process, thereby realizing automatic decontamination treatment.

[0012] When the brush head component needs to be replaced, the first lifting plate is controlled to move upward on the first movable plate, and the second lifting plate is controlled to move upward on the second movable plate, so that the brush head components on both sides can be driven to move upward. Then, the first movable plate and the second movable plate are controlled to slide horizontally on the first slide rail, so that 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 tables, 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 tables, 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, control the first lifting plate and the second lifting plate to move downward a specified distance, and 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, the decontamination mechanism is fully automated, and no additional operation is required by the staff, which greatly improves the surface treatment efficiency of the electronic paper and saves labor costs.

[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 set with the discharge roller 142 and the receiving roller 143 respectively, and the ends of the first rotating shaft 1223 and the second rotating shaft 1224 are respectively provided with a connecting block 12210 for plugging 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 circumferential side 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 connection block 12210, and a transmission belt 1226 is wound around the transmission gear 1225. The driving component of the first clamping part 122 also includes a driving motor 1227 installed on the support plate 1221, and 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, and the second rotating shaft 1224 and the first rotating shaft 1223 are synchronously rotated in the same direction under the transmission action of the transmission belt 1226 and the transmission gear 1225.

[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 movable. 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 with 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 together. After the first protrusion 12214 is aligned with the second splicing groove 1418, a thrust is applied to the connecting block 12210 under the action of the buffer component 1229, so that the connecting block 12210 is automatically plugged into the positioning sleeve 147, and the first protrusion 12214 is automatically embedded in the second splicing groove 1418, thereby achieving an adaptive effect.

[0046] like Fig. 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, 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, 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 fixedly set to the connecting block 12210, and the other end passes through the fixed block 12291 and is fixedly set 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 achieving buffering of 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] In addition, the first clamping part 122 and the second clamping part 123 are both provided with a positioning component, which includes a positioning block 12211 arranged on the same side as the plug-in rod 1222, and a guide rod 12212 is fixedly provided on the positioning block 12211, the guide rod 12212 is slidably arranged on the support plate 1221 and the sliding direction is parallel to the length direction of the second slide rail 121, and a second spring 12213 is provided on the guide rod 12212, and the second spring 12213 is placed between the support plate 1221 and the positioning block 12211 to apply force to the positioning block 12211. After a force is applied to the positioning block 12211 in the direction of the support plate 1221, the guide rod 12212 moves on the support plate 1221, and the second spring 12213 is compressed. When the force applied to the positioning block 12211 stops, the positioning block 12211 automatically resets under the action of the compressed 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 guide grooves 1420 arranged vertically and used for the positioning block 12211 to be embedded. The top opening of the guide groove 1420 is provided with a second bevel 1421 for facilitating the embedding of the positioning block 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 block 12211 is first embedded in the guide groove 1420. However, if the positioning block 12211 is not embedded in the guide groove 1420, it means that the brush head component 14 placed on the brush head placement table 15 is not straightened, so that the plug-in rod 1222 cannot be aligned with the positioning sleeve 147. By providing the positioning block 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 plug-in rod 1222 is aligned with the positioning sleeve 147, and then the support plate 1221 is controlled to move so that the plug-in 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 Fig.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, and the side of the support frame 141 is provided with a plurality of embedded blocks 151 (such as Figure 6 As shown in the figure, 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 accurately replacing the brush head component 14 and avoiding 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 the performance unprecedented in the prior art and become a product with great practical value.
