Description

Technical Field

[0001] The present invention relates to the field of turnover box cleaning devices, and particularly to a vacuum reconditioning turnover box cleaning device and a cleaning system. Background Art

[0002] Vacuum reconditioning is one of the key processes in cigarette production. The cut tobacco slices are sent into a reconditioning turnover box for vacuum reconditioning. After the vacuum reconditioning process, the moisture content of the tobacco slices can be increased by 3% - 5%, and the temperature can reach 70°C, improving the softness and anti-breakage of the tobacco slices, reducing the miscellaneous gas in the tobacco slices, and removing the insect eggs in the tobacco slices.

[0003] The reconditioning turnover box generally has a form with a sealed bottom and mesh holes on the side walls. In the vacuum reconditioning production process, the tobacco slices in the reconditioning turnover box are in a high-temperature and high-humidity environment. Through two vacuum pumping processes, tobacco oil is extremely likely to be generated in the tobacco slices. After the tobacco oil overflows from the tobacco slices, it will adhere to the inner side of the turnover box. If the tobacco slices are not cleaned in time, tobacco oil scale will form on the bottom and side walls of the turnover box and block the mesh holes of the turnover box, which will not only cause the problem of uneven vacuum reconditioning of the tobacco blocks in the turnover box during the processing, but also cause problems such as oil stain aggregation and tobacco insect breeding, affecting the quality of the tobacco slices.

[0004] Currently, the vacuum reconditioning turnover box is mainly cleaned manually. During the batch gap in the production process, after the worker transports the turnover box to the cleaning station, the worker will use high-pressure gas to blow the turnover box to remove the tobacco leaves. After the blowing is completed, the turnover box is transported back to the production station. At the end of the day's production, the worker will transport the turnover box to the cleaning station again and use high-pressure water to thoroughly clean the turnover box. High-pressure gas is used for blowing instead of high-pressure water cleaning between production batches to avoid the appearance of water-stained tobacco leaves in the next batch of tobacco leaves caused by high-pressure water cleaning.

[0005] The existing cleaning method is not only time-consuming and laborious, but also has low production efficiency and high labor input cost. Summary of the Invention

[0006] The purpose of the present invention is to overcome the problem of the effect of removing tobacco leaves by blowing with high-pressure gas in the prior art, and provide a vacuum reconditioning turnover box cleaning device that can efficiently clean the turnover box between batches and ensure production continuity.

[0007] To achieve the above purpose, the present invention provides a vacuum reconditioning turnover box cleaning device, including a first driver and a cleaning mechanism. The cleaning mechanism includes:

[0008] A moving frame, and the first driver is used to drive the moving frame to move;

[0009] A blowing member and a suction member, and both the blowing member and the suction member are installed on the moving frame;

[0010] Wherein, the purging member is used to purge the side wall of the turnover box, and the suction member is used to suck the inner bottom wall of the turnover box.

[0011] In some embodiments, when projected along the direction in which the first driver drives the moving frame to move, the purging member is annular.

[0012] In some embodiments, a plurality of the purging members are provided and are arranged in an annular distribution.

[0013] In some embodiments, more than two suction members are provided.

[0014] In some embodiments, the cleaning mechanism further includes a second driver, which is used to drive the suction member to move, and the moving direction of the suction member is perpendicular to the moving direction of the moving frame.

[0015] In some embodiments, a first guiding member is fixedly installed on the moving frame, and the first guiding member is slidably connected with the suction member.

[0016] In some embodiments, at least two of the first guiding members are slidably connected to the suction member.

[0017] In some embodiments, a connecting member is fixedly connected to the suction member, and the connecting member is connected to the second driver and the first guiding member.

[0018] In some embodiments, the cleaning device further includes a frame and a second guiding member. The first driver is fixedly installed on the frame. The second guiding member is slidably connected with the frame and is fixedly connected with the moving frame;

[0019] Wherein, the direction in which the second guiding member is slidably connected with the frame is the same as the direction in which the first driver drives the moving frame to move.

[0020] The present invention also provides a vacuum reconditioning turnover box cleaning system, including a controller and the cleaning device as described above. The controller is electrically connected to the first driver, the suction member, and the purging member in the cleaning device.

[0021] Applying the above technical solution of the present invention to a vacuum reconditioning turnover box cleaning device has the following effects:

[0022] The moving rack is driven by the first driver to move into the turnover box. During the movement, the purging member purges the residual tobacco flakes on the side wall of the box body. After the moving rack moves to the bottom of the box body, the suction member sucks the residual tobacco flakes on the inner bottom wall of the box body. Finally, the first driver moves the moving rack out of the box body to complete the cleaning process of the turnover box, which is efficient and ensures the production continuity to a certain extent.

[0023] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following provides a detailed description of the specific embodiments of the present invention. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0039] In the present invention, a cleaning device for a vacuum rewetting turnover box is provided. As shown in the attached drawings, the cleaning device includes a first driver 2 and a cleaning mechanism 4. The cleaning mechanism 4 includes a moving frame 46, a blowing member 43, and a suction member 42. The first driver 2 is used to drive the moving frame 46 to move. The blowing member 43 and the suction member 42 are both installed on the moving frame 46, so that the blowing member 43 and the suction member 42 can move together with the moving frame 46. Among them, the blowing member 43 is used to blow the side wall of the turnover box 5, and the suction member 42 is used to suck the inner bottom wall of the turnover box 5. Figure 1 and attached drawings Figure 2 As shown, the turnover box 5 for vacuum rewetting generally has an opening facing upward, a sealed bottom, and several mesh holes on the side wall. During use, the first driver 2 drives the moving frame 46 to move downwards from top to bottom into the turnover box 5, and the blowing member 43 and the suction member 42 move together with the moving frame 46 into the turnover box 5. During the process of the moving frame 46 moving from the opening of the turnover box 5 to the inner bottom of the turnover box 5, the blowing member 43 blows the side wall of the turnover box 5, blowing the tobacco leaves adhered to the side wall of the turnover box 5 to the inner bottom of the turnover box 5 or blowing them outside the turnover box 5. After the moving frame 46 moves to the inner bottom of the turnover box 5, the first driver 2 stops driving. At this time, the suction member 42 sucks the inner bottom wall of the turnover box 5 to suck the tobacco leaves adhered to the inner bottom wall of the turnover box 5. The blowing member 43 works before the suction member 42, so that the suction member 42 can also suck the tobacco leaves blown from the side wall of the turnover box 5 onto the inner bottom wall together, reducing repeated processing.

[0040] As shown in the attached drawings Figure 3 The first driver 2 is preferably but not limited to a driving cylinder, which is used to realize the reciprocating movement of the moving frame 46. The moving frame 46 is fixed to the piston rod of the driving cylinder by fasteners such as bolts. Generally, the first driver 2 drives the moving frame 46 to move at a constant speed, making the entire cleaning device more stable. The blowing member 43 is preferably but not limited to an air knife, which is used to provide a stable air flow for blowing. As shown in the attached drawings

[0041] Figure 4 ​, the air knife is fixed on the moving frame 46 through fasteners such as bolts. The blowing direction of the air knife can be adjusted by the installation angle of the air knife. Generally, the blowing force of the air knife on the side wall of the turnover box 5 is perpendicular to the side wall of the turnover box 5. The suction member 42 is but not limited to a suction hood and can effectively perform the suction work. Generally, an air pump (not shown) needs to be connected to both the blowing member 43 and the suction member 42 to generate corresponding blowing air flow and suction air flow. In addition, a pipe (not shown) needs to be connected to the suction member 42 to export the sucked tobacco leaves.

[0042] In another embodiment, since there are several mesh holes on the side wall of the turnover box 5, the blowing member 43 blowing the side wall of the turnover box 5 from the outside of the turnover box 5 can also meet the blowing effect. Figure 5 As shown in the figure, a part of the moving frame 46 is located outside the turnover box 5 for facilitating the installation of the blowing member 43, so that the blowing member 43 can blow the side wall of the turnover box 5 from the outside to the inside. This blowing method can make the tobacco leaves on the side wall of the turnover box 5 all fall inside the turnover box 5, avoiding the tobacco leaves from falling into the surrounding environment of the turnover box 5. It should be noted that in this embodiment, the moving frame 46 needs to avoid the turnover box 5 during the moving process. Therefore, the moving frame 46 needs to be deformed so that the moving frame 46 can avoid colliding with the turnover box 5 during the moving process.

[0043] In some preferred embodiments, when projected along the moving direction of the moving frame 46 driven by the first driver 2, the blowing member 43 is annular. The annular blowing member 43 can ensure that the entire side wall of the turnover box 5 is blown to ensure the cleaning effect of the side wall of the turnover box 5. It should be noted that the "annular" in this embodiment does not specifically refer to a circular ring. Figure 3 As shown in the figure, the commonly used turnover box 5 is a rectangular box, and the blowing member 43 is in a corresponding rectangular ring shape to better suit the cleaning of the side wall of the rectangular box. Similarly, when the turnover box 5 is a cylindrical box, the blowing member 43 is in a corresponding circular ring shape. Therefore, when using a turnover box 5 of other shapes, the ring shape of the blowing member 43 is preferably a ring shape that matches the inner contour of the turnover box 5 as much as possible.

[0044] In some preferred embodiments, several blowing members 43 are provided and arranged in an annular distribution. Figure 2 and Figure 3 As shown in the figure, the blowing member 43 being annular means that an annular shape is formed by combining several blowing members 43. Such a design facilitates the individual inspection and replacement of each blowing member 43, reduces the maintenance cost, and can also make the blowing member 43 better suit the inner contour of the turnover box 5 and reduce the usage cost of the blowing member 43.

[0045] This will be specifically described by taking the reusable plastic box 5 in the shape of a rectangle as an example. If the purging member 43 itself is in the shape of a rectangular ring, such a purging member 43 generally needs to be customized, and the usage cost of the purging member 43 is high. In this embodiment, four purging members 43 are provided and surrounded to form a rectangle. The structure of each purging member 43 is simpler, and it can be selected from the existing components that can achieve the purging function, so the usage cost of the purging member 43 is low. More specifically, the purging member 43 is selected as an air knife. The air knife itself is in the shape of a strip and is suitable for surrounding a rectangular ring or other polygonal rings.

[0046] In some embodiments, two or more suction members 42 are provided. Generally, during the process of sucking the inner bottom wall of the reusable plastic box 5 by the suction member 42, the working range of suction should cover the entire inner bottom wall of the reusable plastic box 5 as much as possible to ensure the suction effect of the tobacco leaves on the inner bottom wall of the reusable plastic box 5. That is: when one suction member 42 is provided, the suction working range of a single suction member 42 needs to cover the entire inner bottom wall of the reusable plastic box 5, and when two or more suction members 42 are provided, the suction working ranges of all the suction members 42 only need to cover the entire inner bottom wall of the reusable plastic box 5 after being superimposed. In addition, when the suction power of the suction member 42 is constant, the smaller the suction range of the suction member 42 itself, the greater the suction power applied by the suction member 42 to the unit area of the inner bottom wall of the reusable plastic box 5, and the better the suction effect. Therefore, increasing the number of suction members 42 can ensure the suction effect while ensuring that the entire inner bottom wall of the reusable plastic box 5 is covered.

[0047] In some preferred embodiments, the cleaning mechanism 4 further includes a second driver 41. The second driver 41 is used to drive the suction member 42 to move, and the moving direction of the suction member 42 is perpendicular to the moving direction of the moving frame 46. If the suction member 42 is fixed on the moving frame 46, the suction working range of the suction member 42 needs to cover the entire inner bottom wall of the reusable plastic box 5. In this embodiment, however, the suction member 42 can move on the moving frame 46 under the action of the second driver 41, and it is not necessary for the suction working range of the suction member 42 to completely cover the entire inner bottom wall of the reusable plastic box 5. The suction working range of the suction member 42 can be smaller than the inner bottom wall of the reusable plastic box 5, and the suction range compensation is realized by the movement of the suction member 42, so that the suction working range of the suction member 42 only needs to cover the entire inner bottom wall of the reusable plastic box 5. Such a design can make the volume of the main body structure of the suction member 42 more compact, and further increase the suction power of the suction member 42 on the unit area of the inner bottom wall of the reusable plastic box 5 when the suction power of the suction member 42 is constant.

[0048] In this embodiment, when one suction member 42 is provided, the suction member 42 moves under the driving action of the second driver 41 and performs suction treatment on the entire inner bottom wall of the reusable plastic box 5.

[0049] When two or more suction members 42 are provided, the second driver 41 drives all the suction members 42 to move, so that the suction working ranges of all the suction members 42 overlap to cover the entire inner bottom wall of the turnover box 5. Alternatively, the second driver 41 drives some of the suction members 42 to move, and the positions of the other suction members 42 are fixed. After the suction working ranges of all the suction members 42 overlap, they also need to cover the entire inner bottom wall of the turnover box 5.

[0050] Taking the application to the common rectangular turnover box 5 as an example for specific illustration. The second driver 41 adopts a rodless cylinder, and the suction member 42 adopts a suction cover. The length dimension of the suction cover is adapted to the width dimension of the inner bottom wall of the turnover box 5. When one suction member 42 is provided, the rodless cylinder drives the suction cover to move along the length direction of the inner bottom wall of the turnover box 5 from one side of the inner bottom wall of the turnover box 5 to the other side. During the movement, the suction cover performs a suction treatment on the inner bottom wall of the turnover box 5, so as to realize the tobacco leaf suction work on the entire inner bottom wall of the turnover box 5.

[0051] Combined with the attached Figure 6 , in this embodiment, two suction members 42 are provided, and two rodless cylinders are also provided to drive the two suction members 42 to move respectively, and the two suction members 42 move relatively. Compared with the setting method of a single suction member 42, the setting of two suction members 42 shortens the moving distance of each suction member 42. When the moving speed of the suction member 42 and the size of the inner bottom wall of the turnover box 5 are the same, the setting of two suction members 42 shortens the time for the suction work on the inner bottom wall of the turnover box 5 by half.

[0052] Since the two suction members 42 are respectively driven by two rodless cylinders, the movements of the two suction members 42 are independent of each other. Therefore, in other embodiments, the moving directions of the two suction members 42 can be adjusted accordingly, and finally, it is only necessary to satisfy that the suction working ranges of the two suction members 42 overlap to cover the inner bottom wall of the turnover box 5.

[0053] Of course, when two suction members 42 are provided, in some other embodiments, only one rodless cylinder can be provided to drive the two suction members 42 to move, so as to improve the moving synchronism of the two suction members 42 and reduce the problem of movement interference between the two suction members 42.

[0054] It should be noted that when three or more suction members 42 are provided, the moving ranges and moving avoidance plans of the respective suction members 42 are more complex, increasing the design pressure. Moreover, the rectangular turnover box 5 is the most common in actual use. The design structures of the suction member 42 and the second driver 41 in the attached Figure 6 are simple, and it is a relatively preferred embodiment.

[0055] Taking the application to the relatively common cylindrical turnover box 5 as an example for specific illustration. Combined with the attached Figure 7, the second driver 41 uses a rotary motor, and the suction member 42 uses a suction hood. The second driver 41 drives the suction member 42 to rotate so that the suction member 42 performs a suction process on the circular inner bottom wall of the turnover box 5. Rotation is essentially a special moving phenomenon. As shown in the Figure 7 structure on the left, the length dimension of the suction member 42 is adapted to the radius dimension of the inner bottom wall of the turnover box 5. By driving the suction member 42 to rotate through the second driver 41, the entire circular inner bottom wall of the turnover box 5 can be suction-processed. As shown in the Figure 7 structure on the right, the length dimension of the suction member 42 can also be adapted to the diameter dimension of the inner bottom wall of the turnover box 5. By driving the suction member 42 to rotate 180° through the second driver 41, the entire circular inner bottom wall of the turnover box 5 can be suction-processed.

[0056] Taking the application to a special-shaped turnover box 5 as an example for specific description. Combining the Figure 8 figure, in this special-shaped turnover box 5, the inner bottom wall of the turnover box 5 has a rectangular part and a triangular part. Whether the suction member 42 moves or rotates, it cannot completely cover the triangular part. That is, a suction dead angle is formed at the triangular part of the inner bottom wall of the turnover box 5. In this embodiment, two suction members 42 are provided and one rodless cylinder (not shown) is provided. The rodless cylinder drives one of the suction members 42, and the position of the other suction member 42 is fixed. The fixed suction member 42 adopts a shape adapted to the triangular part, and the length of the moving suction member 42 is adapted to the width of the rectangular part. The suction process of the inner bottom wall of the special-shaped turnover box 5 is realized through the cooperation of the fixed suction member 42 and the moving suction member 42.

[0057] In some embodiments, a first guide member 44 is fixedly installed on the moving frame 46, and the first guide member 44 is slidably connected to the suction member 42. Combining the Figure 9 figure and the Figure 10 figure, in this embodiment, the second driver 41 drives the suction member 42 to translate, and the first guide member 44 uses a guide rod fixed on the moving frame 46 to guide the movement of the suction member 42 and improve the movement stability of the suction member 42.

[0058] In some embodiments, at least two first guide members 44 are slidably connected to the suction member 42 to further enhance the movement stability of the suction member 42.

[0059] In some embodiments, a connecting member 47 is fixedly connected to the suction member 42, and the connecting member 47 is connected to the second driver 41 and the first guide member 44. The connecting member 47 serves as an intermediate connecting component, facilitating the assembly connection of the suction member 42 with the second driver 41 and the first guide member 44.

[0060] In some embodiments, combining the Figure 11 figure and the Figure 12, the cleaning device further includes a frame 1 and a second guiding member 45. The first driver 2 is fixedly installed on the frame 1. The second guiding member 45 is slidably engaged with the frame 1 and is fixedly connected to the moving frame 46. Wherein, the sliding connection direction between the second guiding member 45 and the frame 1 is the same as the moving direction of the first driver 2 driving the moving frame 46. The settings of the frame 1 and the second guiding member 45 improve the running stability of the entire cleaning device. In addition, in actual application, the moving frame 46 needs to enter the turnover box 5 from top to bottom. Therefore, the setting of the frame 1 can also raise the initial height of the moving frame 46.

[0061] The present invention also discloses a vacuum rewetting turnover box cleaning system, in combination with the attached Figure 11 and the attached Figure 12 , the cleaning system includes a controller 3 and the cleaning device of any one of the above embodiments. The controller 3 is electrically connected to the first driver 2, the suction member 42, and the purging member 43 in the cleaning device. The setting of the controller 3 facilitates the operation of workers and improves the human-machine interaction. In addition, when a second driver 41 is provided in the cleaning device, the controller 3 can also be electrically connected to the second driver 41 to improve the automation degree of the system.

[0062] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept scope of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0063] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present invention does not separately describe various possible combination methods.

[0064] Furthermore, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, it should also be regarded as the content disclosed by the present invention.
