Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tobacco mechanical equipment, and particularly relates to a maintenance device for an impregnator end cover and a control method thereof. BACKGROUND

[0002] The impregnator is a core key equipment in a carbon dioxide expanded tobacco production line, belongs to a quick-opening door type pressure container, is mainly composed of a cylinder and two upper and lower end covers, and low-temperature high-pressure carbon dioxide liquid is soaked in tobacco here, and every 15 minutes is one process cycle. In each cycle, the upper and lower end covers are opened and closed once, when the impregnator end cover is opened, water vapor in the air is often attached to the surface of the low-temperature cover door to form water droplets, which are adhered to the tobacco, and these water droplets will form thin ice in the subsequent low-temperature process, and if not cleaned in time, a series of problems such as filter screen blockage, poor return of liquid, pipeline overpressure, and cover door unable to be completely sealed will occur.

[0003] Therefore, at the end of each cycle, manual maintenance operations such as defrosting of the filter screen in the end cover, deicing and brushing of glycerol on the front surface of the lock tooth, and brushing of graphite on the back surface of the lock tooth are required, and manual maintenance is time-consuming and laborious and has certain safety hazards.

[0004] In order to solve the above problems, the prior art has developed an automatic cleaning device which can automatically deice, defrost and brush glycerol on the impregnator end cover. For example, a Chinese patent with application number 202021847282.6 discloses an impregnator end cover cleaning device, which comprises a fixed seat and an extension device. One end of the extension device is connected with the fixed seat to form a fixed end, and the other end is a free end. The extension device extends from the fixed end to the free end or shrinks from the free end to the fixed end. The free end of the extension device is connected with a cleaning mechanism. When the impregnator end cover needs to be cleaned, the extension device extends, and the cleaning mechanism cleans the end cover. After cleaning is completed, the extension device shrinks, and the cleaning mechanism is retracted, thereby realizing automatic cleaning of the end cover. However, after each cycle ends, the position of the impregnator end cover after being opened will have some deviation, that is, the impregnator end cover will have more or less displacement when being opened each time. The extension device formed by the scissors structure cannot guarantee that the cleaning mechanism can better fit the end cover of the impregnator each time, and therefore the cleaning effect is poor, and with the increase of use time, the service life of the automatic cleaning device will even be affected.

[0005] Therefore, the present application is proposed. SUMMARY

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0048] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are merely for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0049] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0050] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise explicitly specified and limited.

[0051] As Figures 1 to 3As shown, a kind of dipper end cover maintenance device, comprising: driving mechanism;Cleaning mechanism 10 for cleaning dipper end cover 101;First connecting arm 11, one end is connected with the cleaning mechanism 10, the other end is connected with the driving mechanism, for driving the cleaning mechanism 10 moves to first position, in the first position, the center of rotation of the cleaning mechanism 10 corresponds with the center of the dipper end cover 101;Second connecting arm 12, one end is connected with the cleaning mechanism 10, the other end is connected with the driving mechanism, for driving the cleaning mechanism 10 moves to second position after the cleaning mechanism 10 moves to the first position, in the second position, the plane where the cleaning mechanism 10 is parallel with the plane where the dipper end cover 101 is.

[0052] As shown, Figure 3 After each cycle, the dipper end cover is opened, and the inner side of the dipper end cover needs to be defrosted, deiced and cleaned. Since the position of the dipper end cover after each opening is not fixed, when the dipper end cover is displaced, the existing cleaning mechanism cannot ensure that the cleaning mechanism can better fit the end cover of the dipper each time, so the cleaning effect is poor, and with the increase of use time, it can even affect the service life of the automatic cleaning device.

[0053] Therefore, in the above scheme, the position of the cleaning mechanism 10 is adjusted again for the position of the dipper end cover 101 opened each time, by connecting the cleaning mechanism 10 with the above two connecting arms, by driving the first connecting arm 11 to make the center of the cleaning mechanism 10 correspond with the center of the dipper end cover 101, and then driving the second connecting arm 12 to adjust the plane where the cleaning mechanism 10 is parallel with the plane where the dipper end cover 101 is, and then making the cleaning mechanism 10 contact with the dipper end cover 101 to complete the cleaning and maintenance work, which not only improves the cleaning effect, but also prolongs the service life of the dipper end cover maintenance device 1.

[0054] It should be noted that the dipper end cover 101 on the dipper 100 includes a dipper upper cover and a dipper lower cover, and both the dipper upper cover and the dipper lower cover can be maintained by the dipper end cover maintenance device in the above scheme. When the dipper end cover maintenance device maintains the dipper upper cover, the center of the cleaning mechanism 10 needs to be corresponded with the center of the dipper upper cover by the first connecting arm 11 first, and then the second connecting arm 12 is driven to adjust the plane where the cleaning mechanism 10 is parallel with the plane where the dipper upper cover is.

[0055] In some embodiments, the driving mechanism comprises

[0056] a driving arm 20, the other end of the first connecting arm 11 and the other end of the second connecting arm 12 are connected with the driving arm 20 respectively;

[0057] a driving cylinder 21, a push rod 211 of the driving cylinder 21 is connected with the driving arm 20, for driving the first connecting arm 11 and / or the second connecting arm 12 to move.

[0058] Of course, the driving mechanism can also be a combination of a driving oil cylinder and a driving arm 20, or the driving mechanism includes two driving motors, the other end of the first connecting arm 11 and the other end of the second connecting arm 12 are connected with the driving motors, and the driving motors are used to drive the first connecting arm 11 and / or the second connecting arm 12 to move.

[0059] In some embodiments, the driving arm 20 is in a triangular structure, and the push rod 211, the other end of the first connecting arm 11 and the other end of the second connecting arm 12 are sequentially connected to three corners of the triangular structure respectively;

[0060] Preferably, the first connecting arm 11 and the second connecting arm 12 are arranged in parallel.

[0061] By arranging the driving arm 20 in a triangular structure, and sequentially connecting the push rod 211, the other end of the first connecting arm 11 and the other end of the second connecting arm 12 to three corners of the triangular structure respectively, during the extension and retraction of the push rod 211, the control of the movement of the first connecting arm 11 and the second connecting arm 12 can be realized by controlling one corner of the triangular structure.

[0062] In the initial state of the impregnator end cover 101 with the impregnator end cover maintenance device, by arranging the first connecting arm 11 and the second connecting arm 12 in parallel, the moving speed and the moving distance of the first connecting arm 11 and the second connecting arm 12 are ensured to be equal when moving towards the direction close to the impregnator end cover 101. That is, when the center of the cleaning mechanism 10 driven by the first connecting arm 11 corresponds to and coincides with the center of the impregnator end cover 101, at this time, the second connecting arm 12 will also be at a position close to the impregnator end cover 101, which is convenient for subsequent adjustment of the plane where the cleaning mechanism 10 is located.

[0063] In some embodiments, the driving arm 20 is a triangular frame structure, one side of the triangular frame structure is provided with a first hollow part 22, and the other end of the first connecting arm 11 passes through the first hollow part 22 and is connected with one corner of the triangular frame structure.

[0064] Specifically, as shown in Figure 1As shown, the first connecting arm 11 is connected to one corner of the triangular frame structure through the first hollow part 22, the second connecting arm 12 is connected to one corner of the triangular frame structure close to the cleaning mechanism 10, and the push rod 211 is connected to one corner of the triangular frame structure away from the cleaning mechanism 10.

[0065] In some embodiments, further comprising

[0066] The fixed support 24 is arranged to extend in the vertical direction, and the cylinder body 212 of the driving cylinder 21 is located on one side of the fixed support 24 and fixedly connected to the fixed support 24.

[0067] The triangular frame structure is located on the other side of the fixed support 24, and the corner connected to the other end of the first connecting arm 11 is rotationally connected to the fixed support 24.

[0068] It should be noted that the height of the fixed support 24 arranged to extend in the vertical direction should match the height of the impregnator end cover 101 from the ground. For example, when the impregnator end cover is maintained by the maintenance device for the lower cover of the impregnator, the height of the fixed support 24 will be lower; when the impregnator end cover is maintained by the maintenance device for the upper cover of the impregnator, the height of the fixed support 24 will be higher. It can ensure that the cleaning mechanism 10 can clean the inside of the impregnator end cover 101 in all directions when rotating.

[0069] In some embodiments, two double-ear supports are arranged on one side of the fixed support 24, and a rotating shaft is arranged on each double-ear support, so that the included angle between the driving cylinder 21 and the driving arm 20 is always maintained at a certain angle as the push rod 211 of the driving cylinder 21 extends and retracts.

[0070] In some embodiments, further comprising two brush head mounting parts 25;

[0071] The cleaning mechanism 10 is in a plate-like structure, and the two brush head mounting parts 25 are respectively located at both ends of the plate-like structure and connected to the plate-like structure.

[0072] By installing two brush head mounting parts 25 at both ends of the plate-like structure and installing graphite brush heads on the brush head mounting parts 25, when cleaning ice, frost, and miscellaneous wires inside the impregnator end cover 101, the graphite brush heads at the ends can be used to brush graphite on the outside of the locking teeth located at the outer peripheral edge of the impregnator end cover 101, to complete the "high-difficulty maintenance action" on the outside of the impregnator end cover.

[0073] In some embodiments, as Figure 2As shown, the interior of the plate-shaped structure is hollow, and a transmission bracket 26 is installed on the inner side wall of the plate-shaped structure. The first connecting arm 11 and the second connecting arm 12 are connected to the transmission bracket 26 through a rotating shaft 27.

[0074] Preferably, the plate-like structure is formed by a hollow, flat tube with a rectangular cross-section. The flat tube is preferably made of carbon fiber.

[0075] It should be noted that the form of the plate structure is not limited to this. The plate structure can also be formed by other types of components, as long as the cross-section of the component is rectangular and the interior of the component is hollow to accommodate the transmission bracket 26.

[0076] The rotating shaft 27 can generally be selected from the motor shaft. After the cleaning mechanism 10 is adjusted to the second position, the motor shaft is extended by the drive mechanism, such as the drive motor, so that the cleaning mechanism 10 contacts the inner side of the immersion end cover 101. Then the motor shaft is driven to rotate, thereby driving the cleaning mechanism 10 to rotate, so as to clean the inner side of the immersion end cover 101.

[0077] Preferably, the transmission bracket 26 is installed at the center of the inner sidewall of the plate structure, and the center of the rotating shaft mounting cleaning mechanism 10 is connected to the transmission bracket 26.

[0078] It is understood that the transmission bracket 26 can be integrally cast with the inner wall of the sweeping mechanism 10, or the transmission bracket 26 can be fixedly installed on the inner wall of the sweeping mechanism 10.

[0079] In some implementations, such as Figure 2 As shown, the end of the rotating shaft near the transmission bracket 26 passes through the transmission bracket 26, and a swing block 28 is sleeved on the outer periphery of the end. The two brush head mounting parts 25 are respectively connected to the two ends of the swing block 28 through connecting rods 29.

[0080] Preferably, one end of each of the two brush head mounting portions 25 is provided with a connecting portion 251, and the connecting portion 251 is connected to both ends of the swing block 28 via a connecting rod 29;

[0081] The other end of each of the two brush head mounting portions 25 is provided with a clamping portion 252 for clamping the graphite brush head.

[0082] Specifically, one end of the clamping part 252 is perpendicularly connected to the connecting part 251, and the other end of the clamping part 252 extends inward for mounting a graphite brush head.

[0083] In some embodiments, the transmission bracket 26 is provided with a stopper 30 near each end of the plate-shaped structure, and the two stoppers 30 are arranged in parallel on the sides facing each other;

[0084] The swing block 28 is in a strip-shaped structure, which is located between the two stoppers 30, and the two ends of the strip-shaped structure extend towards the two stoppers 30, so as to abut against the sides of the two stoppers 30.

[0085] Preferably, the stopper 30 is a triangular stopper, and the swing block 28 is symmetrically arranged about the rotation shaft 27 and has a rhombus structure as a whole, which is located between the two triangular stoppers, and the sides of the two triangular stoppers provide a swing space of 120° for the swing block.

[0086] After the cleaning mechanism 10 is tightly attached to the inner side of the dipper end cover 101, a frictional force exists between the cleaning mechanism 10 and the inner side of the dipper end cover 101, so that the swing block does not rotate the cleaning mechanism 10 before abutting against the sides of the triangular stopper. After the swing block moves to the position abutting against the sides of the triangular stopper, the cleaning mechanism 10 starts to rotate to clean the inner side of the dipper end cover 101 by continuing to push the triangular stopper. During the movement of the swing block, one end of the brush head mounting portion 25 also shrinks towards the inside of the cleaning mechanism 10 along with the connecting rod 29, so that the other end of the brush head mounting portion 25 contacts the outer side of the locking tooth structure of the outer peripheral edge of the dipper end cover 101, thereby using the brush head to brush graphite.

[0087] In order to avoid ice and tobacco residue at the center position of the inner side of the dipper end cover 101, it is necessary to control the cleaning mechanism 10 to rotate clockwise by an angle greater than 180° and then rotate counterclockwise by an angle greater than 180°. Preferably, the rotation angle of the cleaning mechanism 10 is controlled to be 190° clockwise or counterclockwise.

[0088] In the above scheme, no additional control elements are needed, and the driving force can be provided only by the rotation of the cleaning mechanism 10, so as to orderly control the position of the brush head mounted on the brush head mounting portion 25, which makes the adjustment more convenient, saves the power mechanism, and greatly reduces the production cost.

[0089] In some embodiments, as Figure 3As shown, the cleaning mechanism 10 further comprises a stopper 31; the side of the triangular frame structure adjacent to the first hollow part 22 is provided with a second hollow part 23, and the stopper 31 abuts against the first connecting arm 11 through the second hollow part 23; after the first connecting arm 11 rotates relative to the dipper end cover 101 to the position where the center of the cleaning mechanism 10 and the center of the dipper end cover 101 coincide, the stopper 31 abuts against the first connecting arm 11, which can lock the first connecting arm 11 relative to the dipper end cover 101, thereby preventing the first connecting arm 11 from continuing to move.

[0090] It should be noted that a torsion spring is arranged between the first connecting arm 11 and the driving arm 20, and the rotating arm pushes the first connecting arm 11 to rotate by means of the torsion spring; when the first connecting arm 11 is rotated to the position, the driving arm 20 continues to rotate, the torsion spring between the first connecting arm 11 and the driving arm 20 is compressed, so that the first connecting arm 11 abuts against the stopper 31 and stops rotating.

[0091] Specifically, as Figure 3 shown, one end of the stopper 31 is mounted on the side wall of the transmission groove 102 left of the windowed part 104, and the other end of the stopper 31 passes through the second hollow part 23 and abuts against the first connecting arm 11. Mounting the stopper 31 on the transmission groove 102 can eliminate the positional error between the transmission groove 102 and the large arm.

[0092] Preferably, the stopper 31 is of L-shaped structure.

[0093] In some embodiments, a plurality of supporting members (not shown in the figure) are further mounted on the side wall of the transmission groove 102 left of the windowed part 104, one end of the supporting member is connected with the side wall of the transmission groove 102, and the other end is connected with the stopper 31. The supporting member is used to support the stopper 31.

[0094] It should be noted that the supporting member and the reinforcing flange of the windowed part of the transmission groove 102 are welded together, or they can be separated and fixedly connected.

[0095] As Figure 3As shown, the opening window part 104 is arranged on the side plate opposite to the turnover door 103 of the conveying groove 102, the fixing support 24 of the end cover maintenance device for the impregnator is installed on the ground outside the conveying groove 102 close to the opening window part 104, and the driving arm 20, the first connecting arm 11, the second connecting arm 12 and the cleaning mechanism 10 extend into the opening window part 104. When the end cover maintenance device for the impregnator is not working, the driving arm 20, the first connecting arm 11, the second connecting arm 12 and the cleaning mechanism 10 are located in a position parallel to the side wall where the opening window part 104 is located. When the end cover maintenance device for the impregnator is about to work, the push rod 211 of the driving cylinder 21 drives the driving arm 20 to rotate, and then drives the first connecting arm 11 and the second connecting arm 12 to rotate together. When the center of the cleaning mechanism 10 coincides with the center of the end cover 101, the stopper 31 abuts against the first connecting arm 11, so that the first connecting arm 11 stops rotating. The push rod 211 of the driving cylinder 21 drives the driving arm 20 to continue to drive the second connecting arm 12 to rotate, so as to adjust the plane where the cleaning mechanism 10 is located to be parallel to the plane where the end cover 101 is located. Then, the motor shaft is used to control the cleaning mechanism to closely adhere to the end cover 101, and then the motor shaft drives the cleaning mechanism to rotate, so as to realize the cleaning and maintenance of the end cover 101.

[0096] The above process is a description of the maintenance process of the lower cover of the impregnator. When the upper cover of the impregnator is maintained, the fixing support 24 of the end cover maintenance device for the impregnator is only installed on the ground close to the upper cover of the impregnator, and the specific operation process is the same as that of the lower cover of the impregnator, which will not be described in detail here.

[0097] The end cover maintenance device 1 for the impregnator provided by the application has the advantages of compact layout and stable structure, can eliminate the safety hazards caused by manual operation, improve the cleaning effect of the end cover 101 of the impregnator, and improve the production efficiency of the expansion line.

[0098] The application further provides a control method of the end cover maintenance device for the impregnator.

[0099] S1: receiving an instruction, controlling the driving mechanism to be in transmission connection with the first connecting arm, and driving the cleaning mechanism to move;

[0100] S2: detecting that the cleaning mechanism moves to a first position, and in the first position, the rotation center of the cleaning mechanism corresponds to the center of the end cover of the impregnator;

[0101] S3: controlling the driving mechanism to be in transmission connection with the second connecting arm, and driving the cleaning mechanism to move to a second position, and in the second position, the plane where the cleaning mechanism is located is parallel to the plane where the end cover of the impregnator is located;
