Description

Technical Field

[0001] This application relates to the field of wet wipe production equipment, and more particularly to a cleaning device for a wet wipe packaging machine. Background Technology

[0002] Rinse-off wet wipes are used for wiping while wet. Their cleaning effect, comfort, and safety are far superior to paper towels. They are commonly used as toilet wipes and are especially suitable for wiping hemorrhoid patients, infants, and hospital patients.

[0003] Chinese Patent No. CN218317734U discloses an air emission device for wet wipe packaging bags, belonging to the technical field of air emission technology for wet wipe packaging bags. The key technical points of the solution include a device body, a guiding mechanism, a flattening mechanism, and a wet wipe body. The device body includes a conveyor belt assembly, which is a conveyor belt. The top of the device body is bolted to the bottom of the flattening mechanism, and the bottom of the flattening mechanism is bolted to the top of the device body. The wet wipe body is placed on top of the device body, and the top of the wet wipe body is in contact with the surface of the flattening mechanism.

[0004] Regarding the aforementioned technologies, when the flattening mechanism squeezes the wet wipe packaging bag, there is a possibility that the additive liquid in the wet wipe packaging bag may be squeezed out, thereby causing contamination to the conveyor belt. Utility Model Content

[0005] To reduce the amount of residue added to the conveyor belt surface, this application provides a cleaning device for a wet wipe packaging machine.

[0006] The cleaning device for a wet wipe packaging machine provided in this application adopts the following technical solution:

[0007] A cleaning device for a wet wipe packaging machine includes a frame and a scraper. The frame is connected to a conveyor belt, and the scraper is connected to the frame. The length direction of the scraper is consistent with the width direction of the conveyor belt. The top of the scraper is used to contact the bottom of the conveyor belt. A collection box is provided below the scraper. The length direction of the collection box is consistent with the length direction of the scraper, and the top of the collection box is open.

[0008] By adopting the above technical solution, when the extruded additive liquid adheres to the surface of the conveyor belt, the additive liquid is transported along with the conveyor belt. Some of the additive liquid is scraped away from the conveyor belt by the scraper and drips into the collection box, thereby reducing the additive liquid on the surface of the conveyor belt and reducing the pollution of the conveyor belt by the additive liquid.

[0009] Optionally, a cleaning roller is rotatably connected to the frame, the length direction of the cleaning roller is consistent with the length direction of the scraper, the cleaning roller is connected to a sponge layer, the sponge layer is used to contact the bottom of the conveyor belt, and the scraper and the cleaning roller are distributed sequentially at intervals along the conveyor belt transport direction.

[0010] By adopting the above technical solution, when the conveyor belt passes the scraper, some of the added liquid follows the conveyor belt and approaches the sponge layer, thereby allowing the sponge layer to absorb the added liquid on the surface of the conveyor belt, further reducing the added liquid on the surface of the conveyor belt and reducing the contamination of the conveyor belt by the added liquid.

[0011] Optionally, the frame is connected to a squeezing roller, the length direction of which is consistent with the length direction of the cleaning roller. The squeezing roller is located below the cleaning roller and contacts the sponge layer. The frame is connected to a clamping member, which is used to drive the squeezing roller to move vertically and drive the squeezing roller to press against the sponge layer.

[0012] By adopting the above technical solution, after the added liquid is absorbed into the sponge layer, the pressing component drives the squeezing roller to move upward in the vertical direction, thereby driving the squeezing roller to press against the sponge layer. The squeezing roller squeezes the sponge layer, causing the added liquid to be discharged from the sponge layer, thereby reducing the amount of added liquid in the sponge layer and improving the cleaning effect of the sponge layer on the conveyor belt.

[0013] Optionally, the cleaning roller includes a support plate, a connecting rod, and a mounting plate. The support plate is rotatably connected to the frame, the connecting rod is connected to the support plate, the length direction of the connecting rod is consistent with the length direction of the scraper, the central axis of the connecting rod is collinear with the central axis of the support plate, the support plate is connected to one end of the connecting rod, the mounting plate is detachably connected to the other end of the connecting rod, the sponge layer is sleeved on the connecting rod, and the sponge layer is disposed between the support plate and the mounting plate.

[0014] By adopting the above technical solution, after long-term use, the sponge layer is prone to adhering impurities or wear. When replacing the sponge layer, the mounting plate is removed from the connecting rod, so that the mounting plate is away from the connecting rod. This makes it easier for the sponge layer to move away from the connecting rod. After the sponge layer is away from the connecting rod, the new sponge layer is put on the connecting rod, and the mounting plate is installed at one end of the connecting rod. This completes the installation of the new sponge layer and facilitates the replacement of the sponge layer.

[0015] Optionally, the frame is provided with a sliding groove, the length direction of which is consistent with the vertical direction. The clamping member includes a slider and a first spring. The slider is slidably connected in the sliding groove along the vertical direction. One end of the extrusion roller is rotatably connected to the slider along its length direction. The length direction of the first spring is consistent with the vertical direction. One end of the first spring along its length direction is connected to the inner wall of the sliding groove, and the other end of the first spring is connected to the bottom of the slider. In use, the first spring is deformed by compression.

[0016] By adopting the above technical solution, when in use, the extrusion roller moves downward under the extrusion of the cleaning roller, and the slider moves downward with the extrusion roller, thereby driving the first spring to deform under the extrusion. The first spring has elasticity and drives the slider and the extrusion roller to move upward in the vertical direction, so that the extrusion roller presses against and squeezes the sponge layer, thereby driving the added liquid to be discharged from the sponge layer.

[0017] Optionally, a connecting block is rotatably connected to one end of the slider along the width direction of the conveyor belt. An installation groove is formed on the periphery of the connecting block, with the length direction of the installation groove aligned with the radial direction of the connecting block. A second spring and a locking block are connected within the installation groove. The length direction of the second spring is aligned with the length direction of the installation groove. One end of the second spring is connected to the inner wall of the installation groove, and the other end is connected to the locking block. The locking block is slidably connected within the installation groove along its length direction. A connecting hole for the locking block to pass through is formed on one side of the slider along the length direction of the conveyor belt, and the connecting hole communicates with the sliding groove. A first locking groove for the locking block to be embedded is formed on the inner wall of one side of the sliding groove along the length direction of the conveyor belt. When the locking block is embedded in the first locking groove, the squeezing roller moves away from the cleaning roller.

[0018] By adopting the above technical solution, during use, the locking block is embedded in the mounting groove and away from the connecting hole. The locking block squeezes the second spring and drives the second spring to deform. When removing the sponge layer, the slider is pushed downward in the vertical direction, so that the squeezing roller is away from the cleaning roller, and the connecting hole is connected to the first locking groove. When the connecting block is rotated, the locking block moves with the connecting block, so that the locking block is close to the connecting hole. When the locking block is close to the connecting hole, the second spring returns to its shape and pushes the locking block to move along the length of the mounting groove and through the connecting hole, so that the locking block is embedded in the first locking groove. This makes the slider stably connected in the sliding groove, so that the squeezing roller is away from the cleaning roller, which makes it easier for the operator to replace the sponge layer.

[0019] Optionally, the locking block has a guide surface on one side of the connecting block in the circumferential direction. The guide surface is inclined so that the locking block can move away from the first locking groove.

[0020] By adopting the above technical solution, after the sponge layer is replaced, the connecting block is rotated, and the guide surface contacts the inner wall of the first locking groove. Under the guidance of the guide surface, the locking block is embedded in the installation groove. The addition of the guide surface makes it more convenient for the locking block to move away from the first locking groove.

[0021] Optionally, the frame is connected to a water collection tank, the top of which is open, and the water collection tank is located below the extrusion roller.

[0022] By adopting the above technical solution and adding a water collection tank, the additive liquid squeezed out by the extrusion rollers from the sponge layer drips into the water collection tank, reducing the pollution of the surrounding environment by the additive liquid.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the extruded additive adheres to the surface of the conveyor belt, the additive is transported along with the conveyor belt. Some of the additive is scraped away from the conveyor belt by the scraper and drips into the collection box, thereby reducing the amount of additive on the surface of the conveyor belt and reducing the contamination of the conveyor belt by the additive.

[0025] 2. After the added liquid is absorbed by the sponge layer, the clamping component drives the squeezing roller to move upward in the vertical direction, thereby driving the squeezing roller to press against the sponge layer. The squeezing roller squeezes the sponge layer, causing the added liquid to be discharged from the sponge layer, thereby reducing the amount of added liquid in the sponge layer and improving the cleaning effect of the sponge layer on the conveyor belt.

[0026] 3. During use, the squeezing roller moves downward under the squeezing action of the cleaning roller, and the slider moves downward with the squeezing roller, which in turn drives the first spring to be squeezed and deformed. The first spring has elasticity and drives the slider and the squeezing roller to move upward in the vertical direction, so that the squeezing roller presses against and squeezes the sponge layer, thereby driving the added liquid to be discharged from the sponge layer.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a cleaning device for a wet wipe packaging machine. (Refer to...) Figure 1 and Figure 2 A cleaning device for a wet wipe packaging machine includes a frame 100 and a scraper 200. The frame 100 is connected to a conveyor belt. The scraper 200 is positioned below the conveyor belt. The scraper 200 is connected to the frame 100, with its length direction aligned with the width direction of the conveyor belt, and its top contacting the bottom of the conveyor belt. The scraper 200 removes the added liquid from the surface of the conveyor belt, reducing the amount of added liquid on the conveyor belt and minimizing contamination.

[0037] Reference Figure 1 and Figure 3 The frame 100 is connected to a collection box 300, the length of which is aligned with the length of the scraper 200, and the top of the collection box 300 is open. The frame 100 is also connected to a cleaning roller 400, and the scraper 200 and cleaning roller 400 are distributed alternately along the conveyor belt direction. The collection box 300 is located below the scraper 200, with the bottom end of the scraper 200 connected to the top of the collection box 300, and the scraper 200 connected to the end of the collection box 300 along the conveyor belt length direction and close to the cleaning roller 400. The top of the scraper 200 is inclined away from the cleaning roller 400.

[0038] Reference Figure 3 and Figure 4The scraper 200 has a mounting block 210 connected to its bottom, and the collection box 300 has a connecting groove 310 on its top. The length of the connecting groove 310 is consistent with the length of the collection box 300, and one end of the connecting groove 310 is open along its length. The mounting block 210 is slidably connected to the connecting groove 310 along the length of the collection box 300. The mounting block 210 is detachably connected to the connecting groove 310 by bolts. The bolts pass through the inner wall of one end of the connecting groove 310 along the length of the conveyor belt and are threaded to the mounting block 210. The scraper 200 is detachably connected to the collection box 300, which facilitates the replacement and cleaning of the scraper 200 and improves the cleaning effect of the scraper 200 on the surface of the conveyor belt.

[0039] Reference Figure 3 and Figure 5 The cleaning roller 400 is aligned with the length of the scraper 200. The cleaning roller 400 includes a support plate 410, a connecting rod 420, and a mounting plate 430. A first motor 110 is connected to the frame 100. The support plate 410 is rotatably connected to the frame 100, and the output shaft of the first motor 110 is connected to the support plate 410. The central axis of the support plate 410 is collinear with the central axis of the output shaft of the first motor 110.

[0040] Reference Figure 3 and Figure 5 The connecting rod 420 has the same length direction as the scraper 200. One end of the connecting rod 420 is connected to the support plate 410 along its length direction, and the central axis of the connecting rod 420 is collinear with the central axis of the support plate 410. Several friction strips 421 are connected to the periphery of the connecting rod 420. The length direction of the friction strips 421 is the same as that of the connecting rod 420, and the friction strips 421 are distributed at equal angles along the circumference of the connecting rod 420. The friction strips 421 are made of rubber. A sponge layer 422 is slidably fitted onto the connecting rod 420. The sponge layer 422 is cylindrical, and its central axis is collinear with the central axis of the connecting rod 420. The length direction of the connecting rod 420 is the same as that of the sponge layer 422, and the sponge layer 422 is slidably connected to the connecting rod 420 along its length direction. The inner ring of the sponge layer 422 contacts the friction strips 421, and the outer ring of the sponge layer 422 contacts the surface of the conveyor belt. The mounting plate 430 is threaded onto the other end of the connecting rod 420, and the sponge layer 422 is disposed between the mounting plate 430 and the support plate 410. A cleaning roller 400 is added. During use, the sponge layer 422 contacts the surface of the conveyor belt, thereby further reducing the amount of liquid added to the surface of the conveyor belt.

[0041] Reference Figure 3 and Figure 5The frame 100 is slidably connected to a squeezing roller 120 and a water collection tank 130. The length direction of the squeezing roller 120 is consistent with the length direction of the cleaning roller 400, and the squeezing roller 120 is located directly below the cleaning roller 400, contacting the sponge layer 422. The length direction of the water collection tank 130 is consistent with the length direction of the squeezing roller 120, and the top of the water collection tank 130 is open, located directly below the squeezing roller 120.

[0042] Reference Figure 3 and Figure 5 The frame 100 is connected to two clamping members 500, which are used to drive the extrusion roller 120 to slide vertically and are connected to the frame 100. The frame 100 has two sliding grooves 140, which are respectively located on both sides of the extrusion roller 120 along the length direction of the extrusion roller 120. The length direction of the sliding grooves 140 is consistent with the vertical direction.

[0043] Reference Figure 3 and Figure 5 Each abutment 500 corresponds one-to-one with a sliding groove 140, and the abutment 500 is disposed within the sliding groove 140. The abutment 500 includes a slider 510 and a first spring 520. The length direction of the first spring 520 is aligned with the vertical direction. The bottom end of the first spring 520 is connected to the inner wall of the bottom of the sliding groove 140, and the top end of the spring is connected to the bottom of the slider 510. The slider 510 slides vertically within the sliding groove 140. The squeeze roller 120 is rotatably connected to the two sliders 510 at both ends along its length direction. The squeeze roller 120 squeezes the sponge layer 422, thereby reducing the amount of added liquid in the sponge layer 422 and improving the cleaning effect of the sponge layer 422 on the conveyor belt.

[0044] Reference Figure 6 and Figure 7 The slider 510 has its length direction aligned with the length direction of the conveyor belt. Two rotating grooves 511 are formed on the slider 510 along the width direction of the conveyor belt, away from the squeeze roller 120. The depth direction of the rotating grooves 511 is aligned with the width direction of the conveyor belt. The two rotating grooves 511 are spaced apart along the length direction of the slider 510.

[0045] Reference Figure 6 and Figure 7 A connecting block 600 is rotatably connected within the rotating groove 511. The length direction of the connecting block 600 is aligned with the width direction of the conveyor belt. The connecting block 600 is cylindrical, and its rotation axis is collinear with the central axis. An installation groove 610 is provided on the circumference of the connecting block 600, and the length direction of the installation groove 610 is aligned with the radial direction of the connecting block 600.

[0046] Reference Figure 6 and Figure 7A second spring 620 and a locking block 630 are connected inside the mounting groove 610. The length direction of the second spring 620 is consistent with the length direction of the mounting groove 610. One end of the second spring 620 along its length direction is connected to the inner wall of the mounting groove 610, and the other end of the second spring 620 is connected to the locking block 630. The locking block 630 is slidably connected to the mounting groove 610 along its length direction.

[0047] Reference Figure 6 and Figure 7 The inner wall of the rotating groove 511 is provided with a second locking groove 512. The length direction of the second locking groove 512 is consistent with the vertical direction. When in use, the locking block 630 is embedded in the second locking groove 512.

[0048] Reference Figure 6 and Figure 7 A connecting hole 513 is provided on the inner wall of the rotating groove 511 along the length of the conveyor belt and away from the other rotating groove 511. The length direction of the connecting hole 513 is consistent with the length direction of the conveyor belt, and the connecting hole 513 connects the sliding groove 140 and the rotating groove 511. The inner walls of both sides of the sliding groove 140 along the length of the conveyor belt are provided with first locking grooves 141 for the locking blocks 630 to be embedded in. The depth direction of the first locking grooves 141 is consistent with the length direction of the conveyor belt. The locking blocks 630 correspond one-to-one with the first locking grooves 141. When the locking blocks 630 are embedded in the first locking grooves 141, the squeezing roller 120 is away from the cleaning roller 400. The locking block 630 has a guide surface on one side of the circumference of the connecting block 600. The guide surface is located at the end of the locking block 630 away from the second spring 620. The guide surface is inclined so that the locking block 630 can move away from the first locking groove 141 or the second locking groove 512. When the locking block 630 is embedded in the first locking groove 141, the guide surface is set downward.

[0049] When replacing the sponge layer 422, move the slider 510 downward so that the connecting hole 513 is connected to the first locking groove 141. Rotate the connecting block 600 so that the locking block 630 passes through the connecting hole 513 and is embedded in the first locking groove 141, thereby making the slider 510 stably connected in the sliding groove 140, which makes it easier for the operator to replace the sponge layer 422.

[0050] The implementation principle of the cleaning device for a wet wipe packaging machine according to this application embodiment is as follows: After the additive liquid adheres to the surface of the conveyor belt, the additive liquid is transported along the conveyor belt. When the conveyor belt passes through the scraper 200, some of the additive liquid is scraped away from the conveyor belt by the scraper 200, and the additive liquid flows into the collection box 300 along the scraper 200, thereby facilitating the collection of the additive liquid. After the conveyor belt passes through the scraper 200, it passes through the cleaning roller 400. The first motor 110 drives the cleaning roller 400 to rotate, so that the sponge layer 422 rotates with the cleaning roller 400. The sponge layer 422 contacts the surface of the conveyor belt and absorbs the additive liquid on the surface of the conveyor belt, further reducing the additive liquid on the surface of the conveyor belt and reducing the pollution caused by the additive liquid to the conveyor belt.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
