Description

Technical Field

[0001] The present application relates to the field of bag cloth scrap removal, and in particular to a cloth scrap removal device and a removal method for bag production. Background Art

[0002] Luggage is a general term for bags used to carry things. A large amount of cloth is used in the production process of luggage. After the luggage is produced and formed, a large amount of cloth scraps will remain and be adsorbed on the surface of the luggage. The common way to remove the cloth scraps from luggage is to use a vibrating stick to loosen and shake off the cloth scraps, and then use a vacuum cleaner to suck away the cloth scraps.

[0003] During the production process, cloth scraps on bags are mainly adsorbed on the surface of bags due to static electricity. The existing technology of loosening and shaking off cloth scraps by vibration is poor, resulting in poor overall cleaning effect of the vibration + vacuum cleaning method, which is difficult to meet production needs. Summary of the invention

[0004] In order to solve the above problems, the present application provides a cloth scrap removal device and a removal method for bag production.

[0005] The cloth scraps removal device for bag production provided in this application adopts the following technical solution: A cloth scraps removal device for bag production, used for removing cloth scraps from the surface of a bag body, comprising: An ion blower, used to remove static electricity from the surface of the bag body; A first cleaning roller and a second cleaning roller, used to contact with the surface of the bag body and clean the cloth scraps on the surface of the bag body, the first cleaning roller and the second cleaning roller are parallel and spaced apart along a first direction, and the first cleaning roller and the second cleaning roller rotate in opposite directions; A feeding belt, conveying the bag body from one side of the first cleaning roller and the second cleaning roller to the other side along a second direction, and conveying the bag body through between the first cleaning roller and the second cleaning roller; a first adsorption plate and a second adsorption plate, wherein the first adsorption plate is used to adsorb the cloth scraps removed from the bag body by the first cleaning roller, and the second adsorption plate is used to adsorb the cloth scraps removed from the bag body by the second cleaning roller; The second direction is perpendicular to the first direction and the rotation axes of the first cleaning roller and the second cleaning roller.

[0006] By adopting the above technical solution, an ion fan is first used to remove static electricity from the bag body to be processed, thereby reducing the adhesion of cloth scraps on the surface of the bag body, so that the cloth scraps can be removed from the surface of the bag body when the subsequent cleaning roller contacts the surface of the bag body. The adsorption plate is provided to adsorb the cloth scraps to prevent them from falling back onto the bag body.

[0007] Further preferably, the cleaning device also includes a stand for installing the ion blower, the first cleaning roller, the second cleaning roller, the feeding belt, the first adsorption plate and the second adsorption plate, and the stand has a feed inlet on one side and a discharge outlet on the other side along the second direction.

[0008] By adopting the above technical solution, the stand can, on the one hand, isolate the cleaning environment from the external environment, preventing the cloth scraps from floating in the air after being cleaned and affecting the processing and production environment; on the other hand, the stand has a feed port and a discharge port along the second direction, that is, the feeding direction of the feed belt, to distinguish between the loading and unloading of the bag body.

[0009] Further preferably, the cleaning device further comprises a transmission mechanism for adjusting the distance between the first cleaning roller and the second cleaning roller along the first direction.

[0010] By adopting the above technical solution, the distance between the first cleaning roller and the second cleaning roller in the first direction can be adjusted so as to be suitable for removing cloth scraps from bag bodies of different sizes.

[0011] Further preferably, the transmission mechanism comprises: a first guide rail, in which a first slider is slidably disposed; A driving gear and a driven gear, the driving gear and the driven gear are meshed and both are rotatably mounted on the first sliding block; a second guide rail, in which a second slider is slidably disposed, and an elastic reset member is connected between the second slider and the second guide rail; A driving pulley, a driven pulley and a tensioning wheel, wherein the driven pulley is coaxially connected to the driving gear, and the tensioning wheel is rotatably mounted on the second slider; A transmission belt connected between the driving pulley, the driven pulley and the tensioning pulley; Wherein, the first cleaning roller is coaxially connected to the driven gear, and the second cleaning roller is coaxially connected to the driving pulley.

[0012] By adopting the above technical solution, after the first cleaning roller and the second cleaning roller come into contact with the bag body, the spacing can be adaptively adjusted and power transmission can be ensured, thereby improving the reliability of the device structure.

[0013] Further preferably, the rotation tangent direction of the first cleaning roller at the contact point between the first cleaning roller and the bag body is opposite to the feeding direction of the feeding belt, and the rotation tangent direction of the second cleaning roller at the contact point between the first cleaning roller and the bag body is opposite to the feeding direction of the feeding belt; The first adsorption plate is located on a side of the first cleaning roller opposite to the feeding direction of the feeding belt, and the second adsorption plate is located on a side of the second cleaning roller opposite to the feeding direction of the feeding belt.

[0014] By adopting the above technical solution, the rotation direction of the first cleaning roller and the second cleaning roller and the feeding direction of the feeding belt are limited, so that the cloth scraps removed from the luggage body by the cleaning roller are located on the side of the part of the luggage body that has not been cleaned, so that even if the removed cloth scraps fall back onto the luggage body, they fall on the surface that has not been cleaned, and can still be cleaned later, so as to ensure the effect of cloth scrap removal; In addition, the relative position of the adsorption plate and the cleaning roller is also set to reduce the removed cloth scraps from falling back onto the surface of the luggage body, so as to ensure the effect of cloth scrap removal.

[0015] Further preferably, the ion blower is of a blowing type and its blowing direction is toward the first adsorption plate and the second adsorption plate, and the ion blower is located on the opposite side of the first adsorption plate and the second adsorption plate along the feeding direction of the feeding belt.

[0016] By adopting the above technical solution, the ion fan adopts a blowing type and limits the blowing direction of the ion fan as well as the position of the ion fan and the position of the adsorption plate, so that the ion fan can not only remove static electricity from the cloth scraps on the surface of the luggage body, but also generate airflow to make the cloth scraps floating in the air flow toward the adsorption plate, so that the adsorption plate can also adsorb the cloth scraps in the air, thereby improving the cloth scraps removal effect.

[0017] Further preferably, the edge of the feeding belt has a rib.

[0018] By adopting the above technical solution, the setting of the retaining edge can prevent the bag body from falling off the feeding belt, thereby improving the feeding reliability.

[0019] Further preferably, a pushing block is fixedly provided on the feeding belt.

[0020] By adopting the above technical solution, during the cleaning process, there will be contact, extrusion and friction between the cleaning roller and the luggage body, which will reduce the moving speed of the luggage body, thereby reducing the efficiency of the entire cleaning process. The setting of the push block can ensure that the feeding moving speed of the luggage body is consistent with the linear speed of the feeding belt, thereby ensuring the cleaning efficiency.

[0021] Further preferably, two feeding belts are provided and used to carry the bag body at the same time, the feeding speed and feeding direction of the two feeding belts are the same, the two feeding belts are parallel and spaced apart along a third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0022] By adopting the above technical solution, two parallel and spaced feed belts are set to feed the bag body, which reduces the contact area between the feed belt and the surface of the bag body while ensuring stable feeding, and reduces the interference of the feed belt on the cleaning roller.

[0023] The present invention also provides a method for removing cloth scraps based on the above-mentioned cloth scraps removing device for bag production, comprising the following steps: S1: placing the luggage to be processed on a conveyor belt, and removing static electricity from the luggage by an ion blower during the conveyor belt conveying the luggage. S2: The first cleaning roller and the second cleaning roller start to rotate, and the first cleaning roller and the second cleaning roller contact the surface of the luggage body, and remove the cloth scraps on the luggage body from the surface of the luggage body; S3: The first adsorption plate and the second adsorption plate adsorb and collect the cloth scraps removed from the surface of the bag body by the first cleaning roller and the second cleaning roller; S4: Detect the cloth scraps content on the surface of the bag body after cleaning; If the test is qualified, the cleaning device continues to operate; If the test fails, after replacing the first cleaning roller, the second cleaning roller, the first adsorption plate and the second adsorption plate, the cleaning device is restarted, and the bag body that fails the test is re-arranged into the queue to be processed.

[0024] In summary, the present application includes at least the following beneficial effects: 1. The main body of the bag is first treated with static electricity removal, and then the cleaning roller is used to remove the static electricity to ensure the cleaning effect of the cloth scraps on the surface of the bag.

[0025] 2. The rotation direction of the cleaning roller is limited to the feeding direction of the feeding belt to prevent the cloth scraps removed from the luggage body from falling back onto the luggage body, thus ensuring the cloth scraps removal effect; 3. The relative position setting of the adsorption plate and the cleaning roller can improve the adsorption effect of the adsorption plate on cloth scraps, thereby reducing the cloth scraps falling back onto the luggage body and ensuring the cloth scraps cleaning effect.

DETAILED DESCRIPTION

[0028] The specific embodiments of the present invention are described in detail below. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] In the present invention, unless otherwise stated, the directional words such as "upper" and "lower" usually refer to the orientation in the assembled state. "Inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0030] The present invention discloses a cloth scrap removal device for bag production, which is used to remove cloth scraps from the surface of a bag body 12. Figure 1 , Attachment Figure 2 The cleaning device includes an ion fan 2, two cleaning rollers, a feeding belt 5 and two adsorption plates.

[0031] The ion blower 2 is used to remove static electricity from the surface of the luggage body 12. The ion blower 2 generates an air stream of charged ions, so that the air stream contacts the surface of the luggage body 12, eliminates static electricity on the surface of the luggage body 12, and reduces the adhesion between cloth scraps and the surface of the luggage body 12, so as to facilitate the subsequent removal of cloth scraps by the cleaning roller. In this embodiment, the ion blower 2 is of a blowing type and its blowing direction is toward the adsorption plate. The ion blower 2 is located on the side of the adsorption plate opposite to the feeding direction of the feeding belt 5. During the cloth scrap removal process, some of the cloth scraps will float in the air after being removed. The use of the above-mentioned air outlet form and position setting of the ion blower 2 can not only complete the function of removing static electricity from the surface of the luggage body 12, but also blow the air toward the adsorption plate under the action of forming an air stream, so that the cloth scraps floating in the air can also be adsorbed by the adsorption plate, thereby improving the cloth scrap removal effect.

[0032] For ease of explanation, the two cleaning rollers are referred to as the first cleaning roller 10 and the second cleaning roller 11, respectively, and are used to contact with the surface of the luggage body 12 and remove cloth scraps on the surface of the luggage body 12. The first cleaning roller 10 and the second cleaning roller 11 are parallel and spaced apart along the first direction. The first cleaning roller 10 and the second cleaning roller 11 have opposite rotation directions, and the rotation axis direction is along the front-to-back direction. The rotation tangent direction of the first cleaning roller 10 at the contact point with the luggage body 12 is opposite to the feeding direction of the feed belt 5, and the rotation tangent direction of the second cleaning roller 11 at the contact point with the luggage body 12 is opposite to the feeding direction of the feed belt 5. In this embodiment, the first direction is the vertical direction, the first cleaning roller 10 is located above the second cleaning roller 11, and the rotation direction of the first cleaning roller 10 is clockwise, and the rotation direction of the second cleaning roller 11 is counterclockwise.

[0033] The feeding belt 5 conveys the luggage body 12 from one side of the first cleaning roller 10 and the second cleaning roller 11 to the other side along the second direction, and the luggage body 12 is conveyed through between the first cleaning roller 10 and the second cleaning roller 11. In this embodiment, the second direction is a horizontal left-right direction, and the feeding belt 5 conveys the luggage body 12 from left to right. That is, the upper surface of the luggage body 12 will contact the lower end of the first cleaning roller 10, and the lower surface of the luggage body 12 will contact the upper end of the second cleaning roller 11. Since the first cleaning roller 10 rotates clockwise, the linear velocity direction of the lower end of the first cleaning roller 10 is horizontal to the left, and after the cloth scraps on the upper surface of the luggage body 12 are removed, the cloth scraps will float to the left side of the first cleaning roller 10; similarly, since the second cleaning roller 11 rotates counterclockwise, the linear velocity direction of the upper end of the second cleaning roller 11 is horizontal to the left, and after the cloth scraps on the lower surface of the luggage body 12 are removed, the cloth scraps will float to the left side of the second cleaning roller 11. Arranging the adsorption plate on the left side of the first cleaning roller 10 and the second cleaning roller 11 can better adsorb the removed cloth scraps.

[0034] It should be noted that in this embodiment, the two cleaning rollers respectively remove the cloth scraps from the upper and lower surfaces of the bag body 12. When the bag body 12 is placed on the feeding belt 5, the surface to be processed on the bag body 12 needs to be in the upper and lower positions.

[0035] For ease of explanation, the two adsorption plates are respectively referred to as the first adsorption plate 9 and the second adsorption plate 8. The first adsorption plate 9 is used to adsorb the cloth scraps removed from the luggage body 12 by the first cleaning roller 10, and the second adsorption plate 8 is used to adsorb the cloth scraps removed from the luggage body 12 by the second cleaning roller 11. The first adsorption plate 9 is located on the side of the first cleaning roller 10 opposite to the feeding direction of the feed belt 5, and the second adsorption plate 8 is located on the side of the second cleaning roller 11 opposite to the feeding direction of the feed belt 5. In this embodiment, the first adsorption plate 9 is arranged on the left side of the first cleaning roller 10, and the second adsorption plate 8 is arranged on the left side of the second cleaning roller 11, and the ion blower 2 is arranged on the left side of the adsorption plate.

[0036] The adsorption board can be a glue-type adsorption board, that is, glue for adhering cloth scraps is coated on the adsorption board. The adsorption board can also be a charged adsorption board, that is, electricity is applied on the adsorption board to adsorb cloth scraps.

[0037] In this embodiment, the first direction is the up and down direction, the second direction is the left and right direction, and the rotation axis direction of the first cleaning roller 10 and the second cleaning roller 11 is along the front and back direction, so the second direction is perpendicular to the first direction and the rotation axis of the first cleaning roller 10 and the second cleaning roller 11.

[0038] In some embodiments, the edge of the feeding belt 5 has a rib 6. The provision of the rib 6 can improve the stability of the bag body 12 during the conveying process to prevent the bag body 12 from falling off the feeding belt 5.

[0039] In some embodiments, a push block 7 is fixed on the feeding belt 5. The push block 7 moves with the feeding belt 5, and the push block 7 limits and pushes the bag body 12, so that the moving speed of the bag body 12 is consistent with the feeding speed of the feeding belt 5, thereby ensuring the cleaning efficiency.

[0040] In some embodiments, two feeding belts 5 are provided and used to carry the luggage body 12 at the same time. The feeding speed and feeding direction of the two feeding belts 5 are the same. The two feeding belts 5 are parallel and spaced apart along the third direction. The first direction, the second direction and the third direction are perpendicular to each other. In this embodiment, the third direction is the attachment Figure 1 The front-to-back direction is Figure 2 The bag body 12 is carried by two feeding belts 5 to ensure feeding stability. The second cleaning roller 11 is located between the two feeding belts 5, so that the position between the feeding belt 5 and the second cleaning roller 11 can be avoided and the second cleaning roller 11 can contact the lower surface of the bag body 12.

[0041] In this embodiment, the feed belt 5 and the cleaning roller are driven to rotate independently. Specifically, the cleaning roller is driven to rotate by a first driving source 13, and the two feed belts 5 are driven to rotate by a second driving source 14. Both the first driving source 13 and the second driving source 14 are motors.

[0042] In some embodiments, the cleaning device also includes a stand 1 for installing an ion blower 2, a first cleaning roller 10, a second cleaning roller 11, a feed belt 5, a first adsorption plate 9 and a second adsorption plate 8, and a feed port 3 is provided on one side of the stand 1 along the second direction, and a discharge port 4 is provided on the other side. Specifically, in this embodiment, the left side of the stand 1 is the feed port 3, and the right side is the discharge port 4. The setting of the stand 1, on the one hand, isolates the processing environment for removing cloth scraps from the external environment to a certain extent, prevents cloth scraps from drifting into the external environment, and ensures that the external environment is clean and tidy. On the other hand, the feed port 3 and the discharge port 4 on the stand 1 are provided to facilitate the distinction and identification of the position on the feed belt 5, so as to avoid the bag body 12 to be cleaned being put in from the right side of the feed belt 5.

[0043] In some embodiments, the cleaning device further includes a transmission mechanism 15 for adjusting the distance between the first cleaning roller 10 and the second cleaning roller 11 along the first direction. The distance between the first cleaning roller 10 and the second cleaning roller 11 is adjustable so as to be suitable for cleaning cloth scraps on the surface of bag bodies 12 of different sizes.

[0044] Specifically, in combination with Figure 3 , Attachment Figure 4 The transmission mechanism 15 includes: a first guide rail 16, in which a first slider 17 is slidably provided; a driving gear 19 and a driven gear 18, in which the driving gear 19 and the driven gear 18 are meshed and both are rotatably mounted on the first slider 17; a second guide rail 21, in which a second slider 22 is slidably provided, and an elastic reset member 24 is connected between the second slider 22 and the second guide rail 21; a driving pulley 26, a driven pulley 20 and a tensioning pulley 23, in which the driven pulley 20 is coaxially connected to the driving gear 19, and the tensioning pulley 23 is rotatably mounted on the second slider 22; a transmission belt 25, connected between the driving pulley 26, the driven pulley 20 and the tensioning pulley 23; wherein the first cleaning roller 10 is coaxially connected to the driven gear 18, and the second cleaning roller 11 is coaxially connected to the driving pulley 26.

[0045] In this embodiment, the transmission mechanism 15 is driven by the first driving source 13. Specifically, the driving pulley 26 is connected to the power output end of the first driving source 13. The setting of the tensioning wheel 23 can ensure the reliability of the power transmission of the transmission belt 25. The setting of the driving gear 19 and the driven gear 18 is to achieve the opposite direction of the first cleaning roller 10 and the second cleaning roller 11. In addition, in other embodiments, the speed ratio between the first cleaning roller 10 and the second cleaning roller 11 can also be controlled by the transmission ratio between the driving gear 19 and the driven gear 18.

[0046] The present invention also provides a method for removing cloth scraps based on the above-mentioned bag production cloth scraps removing device, as shown in the attached Figure 5As shown, the following steps are included: S1: placing the bag body 12 to be processed on the feeding belt 5, and performing static removal treatment on the bag body 12 by the ion blower 2 during the process of the feeding belt 5 conveying the bag body 12; S2: The first cleaning roller 10 and the second cleaning roller 11 start to rotate, and the first cleaning roller 10 and the second cleaning roller 11 contact the surface of the bag body 12, and remove the cloth scraps on the bag body 12 from the surface of the bag body 12; S3: The first adsorption plate 9 and the second adsorption plate 8 adsorb and collect the cloth scraps removed from the surface of the bag body 12 by the first cleaning roller 10 and the second cleaning roller 11; S4: Detecting the cloth scrap content on the surface of the bag body 12 after the cleaning process; If the test is qualified, the cleaning device continues to operate; If the test fails, after replacing the first cleaning roller 10, the second cleaning roller 11, the first adsorption plate 9 and the second adsorption plate 8, the cleaning device is restarted, and the bag body 12 that fails the test is re-arranged into the queue to be processed.
