Description

Technical Field

[0001] The invention relates to the technical field of vacuum bag cleaning, in particular to a cleaning device for vacuum bag transmission. Background Art

[0002] The vacuum bag transmission cleaning device is a cleaning device specially designed for vacuum bags. It aims to clean the dust and impurities on the surface during the rewinding process, thereby ensuring the cleanliness of the vacuum bag during transmission and subsequent use.

[0003] During the transportation of the vacuum bag, due to its large surface area and certain electrostatic adsorption, trace dust in the air will inevitably adhere to the surface of the vacuum bag. In order to ensure that the vacuum bag can be used normally later, its surface must be cleaned. However, there are many problems with the existing cleaning devices for vacuum bag transportation.

[0004] First of all, the airflow cleaning method has significant limitations when cleaning large-area vacuum bags. In actual operation, the flow rate and impact force of airflow cleaning in the central area are relatively large, which can effectively blow away light impurities such as dust from the surface of the vacuum bag, so the central area can often achieve better cleaning effects. However, the situation is completely different in the edge area of ​​the vacuum bag. Due to the distribution characteristics of the airflow, the airflow rate in the edge area is slower and the impact force is weaker, which makes it difficult to completely remove impurities in the edge area. The remaining impurities will re-attach to the surface of the vacuum bag in subsequent processes, or be mixed into the product, thereby affecting product quality.

[0005] Secondly, negative pressure cleaning is to absorb impurities on the surface of the vacuum bag by creating a low-pressure area. During the cleaning process, when the vacuum bag is under negative pressure, its surface will be subjected to uneven force. Since the material of the vacuum bag usually has a certain flexibility, this uneven force will cause depressions or wrinkles on the surface of the vacuum bag. In addition, negative pressure cleaning has a very limited effect on cleaning stains and impurities, because stains and impurities usually have a certain viscosity, and it is difficult to completely remove them from the surface of the vacuum bag relying solely on the adsorption force generated by negative pressure.

[0006] In addition, wiping cleaning achieves the cleaning purpose by means of direct contact between the cleaning piece and the surface of the vacuum bag. During this process, the contact area between the cleaning piece and the vacuum bag is relatively large. On the one hand, the large contact area makes the pressure exerted by the cleaning piece on the surface of the vacuum bag relatively dispersed. When there are relatively stubborn impurities or local unevenness on the surface of the vacuum bag, it is difficult for the cleaning piece to exert enough concentrated pressure to effectively remove these impurities. On the other hand, this large-area contact will increase the risk of damage to the vacuum bag.

[0007] To this end, the present invention provides a cleaning device for vacuum bag transmission. Summary of the invention

[0008] The object of the present invention is to provide a cleaning device for vacuum bag transmission to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a cleaning device for vacuum bag transmission, comprising a rewinder and a rewinding frame, a continuous cleaning component is arranged between the rewinder and the rewinding frame, and the continuous cleaning component comprises a cleaning shell, a cleaning screw and a driving member.

[0010] The cleaning shell is fixedly connected between the rewinding machine and the rewinding frame, and a side of the cleaning shell close to the rewinding machine is arranged in a trapezoidal shape.

[0011] The cleaning screws are provided in two groups with four in total, and the cleaning screws are all rotatably connected to the inside of the cleaning shell. The outer surface of the cleaning screw is provided with a polymer coating, which is specifically a polytetrafluoroethylene coating.

[0012] The driving member is arranged outside the cleaning shell, and the output end thereof is mounted on the surface of the cleaning screw rod, and is used to drive the cleaning screw rod to rotate. The driving member is specifically implemented as a motor.

[0013] Engaging parts are installed on both sides of the outer surface of each cleaning screw rod, and the engaging parts are used to provide the cleaning screw rods located at the upper and lower positions with the function of rotating in opposite directions.

[0014] Preferably, two bristles are fixedly connected inside the cleaning shell and on a side close to the rewinding frame.

[0015] Preferably, the bristles are all arranged at an angle, and the inclination angles of the two bristles are opposite, so as to clean the vacuum bag by their own resistance force.

[0016] Preferably, the cleaning screws located at the top and the bottom form a group, and the thread directions of the cleaning screws in each group are opposite.

[0017] Preferably, the cleaning shell is provided with grooves on the upper and lower surfaces of a side close to the rewinding machine, and non-woven fabric is installed inside the grooves.

[0018] Preferably, there are two driving members in total, and each of the driving members is staggeredly installed on the outer surface of the cleaning screw located below, and the two cleaning screws located below are connected by belt transmission.

[0019] Preferably, the meshing parts include gears and guide plates, and the gears and guide plates are fixedly connected to the outer surface of the cleaning screw, the two gears located at the upper and lower positions are meshed with each other, and the side of the guide plate close to the center of the cleaning screw gradually shrinks to reduce the negative impact of dust on the gears.

[0020] Preferably, a transformer suction assembly is provided on both sides of the cleaning shell, and the transformer suction assembly includes a transformer shell, and the transformer shells are fixedly connected to the outer surface of the cleaning shell, and suction pipes are fixedly connected between the two sides of the transformer shell and the cleaning shell, and a reciprocating member is installed inside the transformer shell, and a piston plate is slidably connected inside the transformer shell, and the bottom of the reciprocating member is fixedly connected to the top of the piston plate, and the reciprocating member is used to provide the piston plate with a reciprocating motion function.

[0021] Preferably, a threaded strip is installed inside the suction pipe.

[0022] Preferably, a through hole is opened inside the transformer shell, a protrusion is provided on the side of the transformer shell away from the cleaning shell, a collecting hole is opened on the side of the transformer shell close to the protrusion, a collecting box is slidably connected to the bottom of the protrusion, and one-way valves are installed at the through hole, the collecting hole and the suction pipe.

[0023] Preferably, three through holes are arranged at equal distances, and the through holes are all located on three inner walls of the transformer shell close to the cleaning shell.

[0024] Preferably, the reciprocating members each include a transmission belt, a half-gear connecting rod, a rack and two springs.

[0025] Preferably, the one-way valves at the through holes are concentric with the through holes and installed on the inner wall of the transformer shell, and their opening direction is the side close to the center of the transformer shell. The one-way valves at the collecting holes are concentric with the collecting holes and installed on the outer wall of the transformer shell, and their opening direction is the side close to the collecting box.

[0026] Compared with the prior art, the beneficial effects of the present invention are: 1. When the vacuum bag passes through the cleaning shell, under the trapezoidal structure, the inclined surface guiding effect is utilized to make the airflow blow away the small dust, thereby realizing the preliminary cleaning of the surface of the vacuum bag. At the same time, the cleaning screws located at the upper and lower positions rotate to perform secondary cleaning of the vacuum bag. During the rotation of the cleaning screw, the contact area between the cleaning screw and the vacuum bag is small and continuous. This contact mode can effectively remove impurities without causing damage to the vacuum bag. Under the action of rotation, dust and impurities are easily brought to both sides of the vacuum bag, effectively avoiding impurity residue. Then the continuous cleaning component improves the cleaning efficiency, helps to ensure the cleanliness of the vacuum bag surface, greatly improves the cleaning effect, and enables the vacuum bag to meet subsequent use requirements, and performs well in both cleaning tiny dust and preventing impurity residue.

[0027] Compared with the prior art, the existing airflow cleaning method has poor cleaning effect on the edge area due to airflow distribution problems when cleaning large-area vacuum bags. The present invention can keep the contact area between the cleaning screw and the vacuum bag consistent by rotating the cleaning screw. Secondly, negative pressure cleaning will affect the flatness of the vacuum bag and has limited cleaning effect on stains and impurities. Wiping cleaning has problems of pressure dispersion and easy breakage. The continuous cleaning component of the present invention overcomes these drawbacks and ensures the integrity and good flatness of the vacuum bag while ensuring the cleaning effect.

[0028] Among them: the bristles of two brushes in opposite directions can comb and clean the vacuum bag from different directions during the cleaning process, which further improves the comprehensiveness and thoroughness of the cleaning and ensures that all parts of the surface of the vacuum bag can be effectively cleaned.

[0029] Among them: during the rotation of the cleaning screw, the upper and lower cleaning screws can generate a relative shear force due to the opposite thread directions. This shear force helps to more effectively remove impurities on the surface of the vacuum bag, especially for those viscous or stubborn impurities, which can be peeled off from the surface of the vacuum bag through this shearing action. At the same time, this design can also keep the vacuum bag stable during the cleaning process, avoiding deviation or deformation due to unilateral force, thereby ensuring the accuracy and stability of cleaning.

[0030] Among them: when the vacuum bag passes through the cleaning shell, the blown dust will be adsorbed onto the non-woven fabric under the drive of the airflow, effectively preventing the dust from falling back onto the surface of the vacuum bag again; secondly, the non-woven fabric can also adsorb dust in the production environment, further improving the dust control ability of the continuous cleaning component and reducing the influence of external dust on the cleaning effect of the vacuum bag.

[0031] In summary, since the entire cleaning process is relatively gentle and efficient, it will not cause potential damage to the material of the vacuum bag, which helps to extend the service life of the vacuum bag. At the same time, the continuous cleaning component structure is relatively simple and compact, and the installation and maintenance costs in the actual production environment are low. This is very beneficial for large-scale industrial production, and can reduce production costs while improving production efficiency and product quality.

[0032] 2. The piston plate is driven to reciprocate inside the transformer shell by the cooperation of the reciprocating parts and the driving parts, so that the piston plate can continuously extract the air inside the clean shell, and absorb the dust and other impurities contained therein into the transformer shell through negative pressure. During the transmission of the vacuum bag, the air extracted by the piston plate effectively avoids the dust raised by the continuous transportation of the vacuum bag, thereby preventing the vacuum bag from being contaminated again. This active air purification mechanism greatly improves the cleaning effect of the vacuum bag, ensuring that the vacuum bag can remain clean after cleaning to meet subsequent use requirements, and also helps to maintain the cleanliness of the internal environment of the entire continuous cleaning component.

[0033] Among them: under the action of negative pressure, the air containing dust is sucked into the suction pipe and discharged into the transformer shell, and the threaded strips inside the suction pipe make the dust air move in a spiral motion. On the one hand, the spiral motion can prevent the dust from clogging and adhering to the suction pipe. On the other hand, the spiral motion promotes full contact of the dust, making it easier for the dust to agglomerate. The mass of the dust particles after agglomeration is increased and easier to be collected.

[0034] Among them: when the piston plate compresses the air inside the transformer shell, the dust is pushed into the collection box under the action of pressure. This process forms a complete dust handling mode, which separates the dust from the environment in which the vacuum bag is transported. The separated environment ensures that the vacuum bag is in a relatively dust-free environment during the cleaning process, avoiding the possibility of dust adhering to the surface of the vacuum bag again. At the same time, the complete dust handling mode helps to centrally handle dust and reduce the spread of dust in the continuous cleaning components and transformer suction components.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that the rewinding machine 11 and the rewinding frame 12 only provide the function of rewinding the vacuum bag. Similarly, the one-way valve 35 only provides a one-way flow channel for the airflow, and the working principle and specific structure of the above structure are both existing technologies. Therefore, in view of the versatility of the above structure, its specific principle will not be repeated later.

[0051] Example 1, please refer to Figures 1 to 8 As shown, a cleaning device for vacuum bag transmission includes a rewinder 11 and a rewinding frame 12, a continuous cleaning assembly 2 is arranged between the rewinder 11 and the rewinding frame 12, and the continuous cleaning assembly 2 includes a cleaning shell 21, a cleaning screw rod 22 and a driving member 23.

[0052] The cleaning shell 21 is fixedly connected between the rewinding machine 11 and the rewinding frame 12 , and a side of the cleaning shell 21 close to the rewinding machine 11 is arranged in a trapezoidal shape.

[0053] There are two groups of four cleaning screws 22 , and the cleaning screws 22 are all rotatably connected to the inside of the cleaning shell 21 . The outer surface of the cleaning screw 22 is provided with a polymer coating, specifically a polytetrafluoroethylene coating.

[0054] The driving member 23 is disposed outside the cleaning housing 21 , and an output end thereof is mounted on an outer surface of the cleaning screw 22 , and is used to drive the cleaning screw 22 to rotate. The driving member 23 is specifically implemented as a motor.

[0055] Engaging members 25 are installed on both sides of the outer surface of each cleaning screw rod 22. The engaging members 25 are used to provide the cleaning screw rods 22 at the upper and lower positions with the function of rotating in opposite directions.

[0056] Please refer to Figures 4 to 8 As shown, two bristles 24 are fixedly connected inside the cleaning shell 21 and on one side close to the rewinding frame 12, and the engaging parts 25 include gears and guide plates, which are fixedly connected to the outer surface of the cleaning screw 22, and the two gears located at the upper and lower positions are meshed with each other, and the side of the guide plate close to the center of the cleaning screw 22 is gradually contracted to reduce the negative impact of dust on the gears.

[0057] It should be noted that the bristles 24 are all arranged at an angle, and the inclination angles of the two bristles 24 are opposite, and they are used to clean the vacuum bag by their own resistance force. The cleaning screws 22 located above and below are a group, and the thread directions of each group of cleaning screws 22 are opposite. The cleaning shell 21 is close to the side of the rewinder 11, and grooves are provided on the upper and lower surfaces, and non-woven fabric is installed inside the grooves. There are two driving members 23, and each driving member 23 is staggeredly installed on the outer surface of the cleaning screw 22 located below, and the two cleaning screws 22 located below are connected by a belt drive.

[0058] Specifically, after the operator installs the vacuum bag between the rewinding machine 11 and the rewinding frame 12 , the rewinding machine 11 , the rewinding frame 12 and the driving member 23 are started.

[0059] At this time, the rewinder 11 starts to operate, and the vacuum bag is continuously rewound onto the rewinding frame 12 . During this process, the vacuum bag passes through the interior of the cleaning shell 21 and is continuously transferred to the rewinding frame 12 .

[0060] First, when the vacuum bag passes through the cleaning shell 21, since the side of the cleaning shell 21 close to the rewinder 11 is set in a trapezoidal shape, the passage of the vacuum bag will cause the trapezoidal structure to be separated, thereby forming two inclined planes. According to the principles of fluid mechanics, when the air flows near these two inclined planes, a special airflow field will be formed, and the small dust particles on the surface of the vacuum bag will be affected by the force of the airflow, and this force can be decomposed into a component parallel to the inclined plane and a component perpendicular to the inclined plane. The component parallel to the inclined plane will cause the dust to move along the inclined plane, while the component perpendicular to the inclined plane will cause the small dust to overcome the adsorption force with the surface of the vacuum bag, thereby falling off the surface of the vacuum bag.

[0061] It should be noted that since non-woven fabric is installed inside the groove on the surface of the cleaning shell 21, when the dust on the surface of the vacuum bag starts to move under the action of the inclined guided airflow, the non-woven fabric can absorb the moving dust to prevent the dust from being lifted up again inside the cleaning shell 21 and re-attaching to the vacuum bag. Secondly, the non-woven fabric can also absorb dust in the surrounding environment of the continuous cleaning component 2 to reduce the interference of external dust on the cleaning process of the vacuum bag. Finally, since the non-woven fabric is installed in the groove, when the non-woven fabric absorbs dust to a certain extent, it can be easily replaced to ensure its continued effective adsorption function.

[0062] At the same time, the driving member 23 drives the cleaning screw 22 to rotate. Due to the action of the engaging members 25 on both sides of the outer surface of each cleaning screw 22, the cleaning screws 22 located at the upper and lower positions will rotate in opposite directions.

[0063] During the rotation of the cleaning screw 22, since its outer surface is provided with a polytetrafluoroethylene coating, which has a low friction coefficient and good wear resistance, the rotation of the cleaning screw 22 will not cause damage to the surface of the vacuum bag. When the cleaning screw 22 contacts the surface of the vacuum bag, the contact area is small and continuous due to the presence of its threads.

[0064] This contact mode makes the pressure exerted by the cleaning screw 22 on the surface of the vacuum bag relatively uniform. Specifically, the force exerted by the cleaning screw 22 on the surface of the vacuum bag when rotating is mainly tangential force, which can effectively remove dust and impurities on the surface of the vacuum bag. Since the contact area is small, the pressure per unit area will not be too large, so the surface of the vacuum bag will not be damaged.

[0065] It should be noted that during the rotation of the cleaning screw 22, dust and impurities will be gradually cleaned up driven by the cleaning screw 22, and the dust will be continuously rotated by its thread and brought to the edge of the vacuum bag. At the same time, the guide plate in the engaging member 25 close to the side of the center of the cleaning screw 22 gradually shrinks. Therefore, during the cleaning process, the dust and impurities brought to the outside of the vacuum bag are easily driven by the contraction trend of the guide plate and dispersed to the inner walls on both sides of the cleaning shell 21, thereby further ensuring that the dust will not interfere with the vacuum bag that has been cleaned.

[0066] Finally, when the vacuum bag passes through the bristles 24 on the side of the rewinding frame 12 inside the cleaning shell 21, since the bristles 24 are arranged at an angle and the inclination angles of the two bristles 24 are opposite, when the vacuum bag contacts the bristles 24, the bristles 24 will use their own resistance force to clean the vacuum bag. From a microscopic perspective, the inclined bristles 24 are like a microscopic comb-like structure, which can comb and clean the vacuum bag from different directions, ensuring that the cleanliness of the surface of the vacuum bag reaches a higher standard.

[0067] After this series of cleaning processes, the cleaned vacuum bag is finally rolled up by the rewinding frame 12 .

[0068] Example 2, based on Example 1, please refer to Figures 9 to 11 As shown, a transformer suction assembly 3 is provided on both sides of the clean shell 21, and the transformer suction assembly 3 includes a transformer shell 31, and the transformer shell 31 is fixedly connected to the outer surface of the clean shell 21, and a suction pipe 32 is fixedly connected between the two sides of the transformer shell 31 and the clean shell 21, and a reciprocating member 33 is installed inside the transformer shell 31, and a piston plate 34 is slidably connected inside the transformer shell 31, and the bottom of the reciprocating member 33 is fixedly connected to the top of the piston plate 34, and the reciprocating member 33 is used to provide the piston plate 34 with a reciprocating motion function.

[0069] It should be noted that a threaded strip is installed inside the suction pipe 32, a through hole is opened inside the transformer shell 31, and there are three through holes equidistantly arranged, and the through holes are all located on the three inner walls of the transformer shell 31 close to the cleaning shell 21, and a protrusion is arranged on the side of the transformer shell 31 away from the cleaning shell 21, and a collecting hole is opened on the side of the transformer shell 31 close to the protrusion, and a collecting box is slidably connected to the bottom of the protrusion, and a one-way valve 35 is installed at the through hole, the collecting hole and the suction pipe 32, and the reciprocating member 33 includes a transmission belt, a half gear connecting rod, a rack and two springs, and the half gear connecting rod rotates to connect It is connected to the inside of the transformer shell 31, the transmission belt is connected between the motor output shaft and the half-gear connecting rod, the rack is fixedly connected to the top of the piston plate 34, and the rack and the half-gear connecting rod are meshed with each other, the springs are fixedly connected between the inner wall of the transformer shell 31 and the top of the piston plate 34, the one-way valves 35 at the through holes are concentric with the through holes and installed on the inner wall of the transformer shell 31, and the opening direction is the side close to the center of the transformer shell 31, the one-way valves 35 at the collecting holes are concentric with the collecting holes and installed on the outer wall of the transformer shell 31, and the opening direction is the side close to the collecting box.

[0070] Specifically, based on the first embodiment, when the driving member 23 is started, the transmission belt connects the output shaft of the driving member 23 with the half-gear connecting rod in the transformer suction assembly 3, and the rotation of the motor will drive the half-gear connecting rod to rotate. The half-gear connecting rod is meshed with the rack fixedly connected to the top of the piston plate 34. This special connection method between the half-gear connecting rod and the rack makes them not in a continuous meshing relationship.

[0071] When the half-gear connecting rod rotates, it drives the rack to move. When the half-gear connecting rod is not meshed with the rack, since the spring is fixedly connected between the inner wall of the transformer housing 31 and the top of the piston plate 34, the elastic restoring effect of the spring will be brought into play, driving the rack to move in the opposite direction. In this way, the continuous rotation of the driving member 23 can drive the rack to move up and down. Since the rack and the piston plate 34 are fixedly connected, the piston plate 34 will also reciprocate with the rack, thereby realizing the continuous extraction and compression of the air inside the transformer housing 31.

[0072] During the process of the piston plate 34 extracting air, the amount of air inside the transformer shell 31 gradually increases. According to the ideal gas state equation, when the volume increases, the pressure will decrease, thereby forming a negative pressure environment inside the transformer shell 31. At this time, the inside of the clean shell 21 is in a high-pressure state relative to the inside of the transformer shell 31. Under the action of the pressure difference, the air inside the clean shell 21 will generate thrust on the one-way valve 35, allowing the air to enter the inside of the transformer shell 31.

[0073] Specifically, at the through hole of the transformer shell 31 closest to the cleaning shell 21, since the opening direction of the one-way valve 35 here is to the side close to the center of the transformer shell 31, the air inside the cleaning shell 21 will directly push open the one-way valve 35 here and enter the transformer shell 31, while for the other two sides of the transformer shell 31, the air will enter the transformer shell 31 through the suction pipe 32.

[0074] It should be noted that in this process, the air will push open the one-way valve 35 at the suction pipe 32 and enter the transformer shell 31. Since the suction pipe 32 is provided with a threaded strip inside, the air will flow in the suction pipe 32 in a spiral motion, and the spiral motion makes it difficult for dust particles to gather together during the flow. In conventional linear flow, dust particles are easy to accumulate in certain parts of the pipe, and the centrifugal force generated by the spiral motion will cause the dust particles to constantly change their motion trajectory to prevent them from staying in one place for a long time, thereby effectively preventing dust from gathering and clogging the pipe. Secondly, the spiral motion increases the chance of collision between dust particles. When dust particles collide with each other, they will adsorb each other and gradually form a cluster. The clustered dust particles are easier to handle in the subsequent collection process, thereby improving the efficiency of dust collection.

[0075] When the piston plate 34 draws air, the air containing dust in the cleaning shell 21 will enter the transformer shell 31. When the piston plate 34 moves in the opposite direction and starts to compress the air, due to the special setting of the opening direction of the one-way valve 35 in the transformer shell 31 and the airflow discharge direction, the air and dust cannot flow out in the opposite direction through the one-way valve 35 at the suction pipe 32, and can only push the one-way valve 35 at the collecting hole under the action of pressure. Because the opening direction of the one-way valve 35 at the collecting hole is close to the side of the collecting box, the air and dust can smoothly pass through the collecting hole into the collecting box.

[0076] This process is repeated over and over again, and the air inside the cleaning shell 21 is continuously processed during the entire vacuum bag transmission process, and the dust therein is collected into a collection box. When a batch of vacuum bags is transmitted, the operator needs to stop the equipment to replace a new vacuum bag.

[0077] At this time, since the equipment stops running, the operator can easily slide the collection box out from the raised bottom of the transformer shell 31 to clean the dust in the collection box.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
