Description
Technical Field
[0001] This utility model relates to the field of automatic cleaning device technology, and in particular to a cleaning device for the vibrating groove of a heating and humidifying equipment. Background Technology
[0002] A tobacco leaf heating and humidification machine is a piece of equipment used in tobacco processing. It primarily increases the temperature and moisture content of tobacco leaves, effectively improving the quality of tobacco stems. The SIROX heating and humidification machine, a type of tobacco leaf heating and humidification machine, consists of a feeding hood, a vibrating trough, a vibrating trough cover, a dehumidification pipe, and a discharge hood. Its working principle involves heating, humidifying, and expanding the tobacco leaves using a large amount of saturated steam. The leaves are then rapidly dried in a downstream drying machine, where the moisture within the leaf cells evaporates quickly, causing the leaves to set rapidly. The vibrating trough transports the tobacco leaves, the dehumidification pipe removes excess steam, and a cleaning mechanism cleans the vibrating trough to prevent the accumulation of tobacco dust, leaf fragments, powder, and residues formed by condensation.
[0003] Traditional cleaning mechanisms are often directly fixed to the vibrating trough cover, with the nozzles facing the trough for easy cleaning. This setup causes steam to accumulate and condense at the nozzle protrusions during production, forming condensate that drips into the tobacco leaves, creating wet tobacco clumps. This can easily lead to yellow spots on the tobacco, affecting its quality.
[0004] Therefore, there is an urgent need for a cleaning device for the vibrating groove of heating and humidifying equipment that can solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to provide a cleaning device for the vibrating groove of a heating and humidifying equipment, which has two states. In the non-working state, it can prevent steam from accumulating and condensing at the nozzle, thus avoiding the situation where condensate drips into the material and affects product quality; at the same time, steam will not overflow in the non-working state.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A cleaning device for a vibrating trough in a heating and humidifying equipment, the vibrating trough including a conveying chamber and a cover plate fastened to the vibrating trough, the cleaning device comprising:
[0008] The first pipe fitting and the sealing fitting are provided with a nozzle at the end of the first pipe fitting and a through hole on the cover plate. The first pipe fitting can move along its own axial direction to pass through the through hole or disengage from the through hole.
[0009] The cleaning device has a working state and a non-working state. When the cleaning device is in the working state, the first pipe passes through the through hole to allow the nozzle to enter the delivery chamber. When the cleaning device is in the non-working state, the first pipe disengages from the through hole to allow the nozzle to exit the delivery chamber, and the sealing member blocks the through hole.
[0010] Preferably, the sealing element is connected to the end of the first pipe, and the sealing element and the nozzle are spaced apart along the axial direction of the first pipe.
[0011] Preferably, the cleaning device further includes a connecting rod that extends axially along the first pipe, with one end connected to the end of the first pipe near the nozzle and the other end connected to the sealing member.
[0012] Preferably, the sealing element includes a conical cap with its tip facing the nozzle, and the connecting rod is connected to the outer wall of the conical cap.
[0013] Preferably, the diameter of the bottom end of the conical cover is not less than the diameter of the through hole.
[0014] Preferably, the cleaning device further includes a drive assembly, the output end of which is connected to the first pipe fitting, and the fixed end of which is connected to an external structure. The drive assembly is used to drive the first pipe fitting to move along its own axial direction.
[0015] Preferably, the cleaning device further includes a connecting plate, one side of which is connected to the output end of the drive assembly, and the other side is connected to the outer wall of the first pipe.
[0016] Preferably, the cleaning device further includes a sensing component, which sends a signal when the sealing member blocks the through hole, and the driving component stops driving the first pipe.
[0017] Preferably, the cleaning device further includes a second pipe and a cleaning material tank. One end of the second pipe is coaxially connected to the end of the first pipe away from the nozzle, and the other end is connected to the outlet of the cleaning material tank. The cleaning material in the cleaning material tank can enter the first pipe through the second pipe.
[0018] Preferably, the second pipe fitting is capable of deformation.
[0019] The beneficial effects of this utility model are:
[0020] This utility model proposes a cleaning device for a vibrating trough in a heating and humidifying equipment, comprising a first pipe and a sealing component. A nozzle is provided at the end of the first pipe, and a through hole is provided on the cover plate of the vibrating trough. The first pipe can move along its own axial direction to pass through or disengage from the through hole. Specifically, the cleaning device has a working state and a non-working state. When the cleaning device is in the working state, the first pipe passes through the through hole, allowing the nozzle to enter the conveying chamber. At this time, the nozzle can perform a cleaning action on the cavity wall of the conveying chamber. When the cleaning device is in the non-working state, the first... The nozzle detaches from the through-hole and exits the conveying chamber, while the sealing component blocks the through-hole. At this time, since the nozzle is no longer in the conveying chamber, steam can be prevented from accumulating and condensing at the nozzle, causing condensate to drip onto the blades and affecting product quality. In addition, when the cleaning device is not in operation, the sealing component can block the through-hole to seal the conveying chamber, preventing steam from overflowing and affecting the heating and humidification process of the blades in the conveying chamber. At the same time, the sealing component blocks the through-hole to prevent foreign objects from entering the conveying chamber through the through-hole and contacting the blades, thereby affecting product quality.

[0031] like Figures 1 to 4As shown, this embodiment proposes a cleaning device for a vibrating trough of a heating and humidifying equipment, including a first pipe 1 and a sealing component. A nozzle 11 is provided at the end of the first pipe 1, and a through hole 91 is provided on the cover plate 9 of the vibrating trough 8. The first pipe 1 can move along its own axial direction to pass through or disengage from the through hole 91. Specifically, the cleaning device has a working state and a non-working state. When the cleaning device is in the working state, the first pipe 1 passes through the through hole 91, allowing the nozzle 11 to enter the conveying chamber 81. At this time, the nozzle 11 can perform a cleaning action on the cavity wall of the conveying chamber 81. When the cleaning device is in the non-working state, the first pipe 1... Disengaging through hole 91 causes nozzle 11 to exit the conveying chamber 81, and the sealing element blocks through hole 91. Since nozzle 11 is no longer inside the conveying chamber 81, steam accumulation and condensation at nozzle 11 are prevented, thus avoiding condensate dripping into the material and affecting product quality. Furthermore, when the cleaning device is not in operation, the sealing element blocks through hole 91, sealing the conveying chamber 81 and preventing steam from overflowing and affecting the heating and humidification process of the blades within the conveying chamber 81. Simultaneously, the sealing element blocks through hole 91, preventing foreign objects from entering the conveying chamber 81 through hole 91 and contacting the blades, thereby affecting product quality. In this embodiment, the heating and humidification equipment uses a SIROX heating and humidification machine.
[0032] It needs to be explained that in the heating and humidifying equipment, the vibration trough 8 is essentially a physical entity, not a virtual one. It is an independent structural component that achieves physical movement through a vibration motor or drive mechanism. In the heating and humidifying equipment, the vibration trough 8 serves as a carrier for material conveying, directly carrying materials (such as blades) and promoting the uniform distribution of heat and moisture through high-frequency vibration.
[0033] This cleaning device has two operating states: working and non-working, which match the working state of the vibrating trough 8. When the vibrating trough 8 is idle, the cleaning device can be in the working state, with the first pipe 1 passing through the through hole 91, and the nozzle 11 performing a cleaning action on the cavity wall of the conveying chamber 81. When the vibrating trough 8 is transporting the blades, the conveying chamber 81 is filled with steam, and the cleaning device should be in the non-working state. The first pipe 1 is disengaged from the through hole 91, the nozzle 11 is not in the conveying chamber 81, and the sealing member blocks the through hole 91. Since the nozzle 11 is not in the conveying chamber 81, the steam in the conveying chamber 81 will not accumulate at the nozzle 11 to form condensate. At the same time, the sealing member blocks the through hole 91 on the cover plate 9, and the steam in the conveying chamber 81 will not overflow from the through hole 91.
[0034] Furthermore, the first pipe fitting 1 and the sealing component are interconnected, and the nozzle 11 and the sealing component are spaced apart along the axial direction of the first pipe fitting 1. When the cleaning device switches states, that is, when the first pipe fitting 1 moves along its own axial direction to pass through or disengage from the through hole 91, it can directly drive the nozzle 11 and the sealing component to move simultaneously, thereby controlling the specific positions of the nozzle 11 and the sealing component. Compared with setting a movable sealing component separately on the cover, this simplifies the operation steps, reduces manufacturing costs, improves work efficiency, reduces the number of parts, reduces failure points, and makes cleaning and maintenance simpler. In addition, the distance between the spaced nozzle 11 and the sealing component should not be too long to avoid the nozzle 11 not entering the conveying chamber 81 before the sealing component is located inside the conveying chamber 81 or even abuts against the bottom of the conveying chamber 81, thus affecting the cleaning action. The distance between the nozzle 11 and the sealing component should also not be too short to avoid the sealing component affecting the spraying action of the nozzle 11.
[0035] The cleaning device also includes a connecting rod 3, which extends axially along the first pipe 1. One end of the connecting rod 3 is connected to the end of the first pipe 1 near the nozzle 11, and the other end is connected to the sealing member. The connecting rod 3 is used to connect the first pipe 1 and the sealing member, and the axial extension of the connecting rod 3 along the first pipe 1 causes the sealing member and the nozzle 11 to be spaced apart axially along the first pipe 1.
[0036] Furthermore, to ensure the connection strength between the first pipe fitting 1 and the sealing component, at least two connecting rods 3 can be provided. In this embodiment, the number of connecting rods 3 is two.
[0037] Preferably, the sealing component includes a conical cap 2, with its tip facing the nozzle 11, and a connecting rod 3 connected to the outer wall of the conical cap 2. When the conical cap 2 is used to seal the through hole 91, its side wall can abut against the edge of the through hole 91. Moreover, the conical cap 2 moves axially along the first pipe 1, and when sealing the through hole 91, it can convert the axial tension into radial expansion force to achieve sealing. Compared with ordinary flat caps, it has a self-tightening effect and can maintain sealing strength under various working conditions.
[0038] In addition, the tip of the conical cover 2 is positioned towards the nozzle 11. At this time, the conical cover 2 can also act as a fluid distributor. The conical slope can guide the fluid close to the nozzle 11 to the outside, expand the spraying area, and improve cleaning efficiency.
[0039] Furthermore, the bottom diameter of the conical cover 2 is not less than the diameter of the through hole 91 to prevent the bottom of the conical cover 2 from failing to completely cover the through hole 91, thus preventing sealing failure of the conveying cavity 81. Specifically, when the bottom diameter of the conical cover 2 is equal to the diameter of the through hole 91, when the conical cover 2, along with the first pipe fitting 1, completely exits the conveying cavity 81, the bottom of the conical cover 2 just contacts the cover plate 9, completely sealing the through hole 91. When the bottom diameter of the conical cover 2 is greater than the diameter of the through hole 91, the conical cover 2 cannot pass through the through hole 91 as a whole, thus failing to seal the through hole 91. It should be explained that when the bottom diameter of the conical cover 2 is greater than the diameter of the through hole 91, the conical cover 2 is always at least partially located in the conveying chamber 81, regardless of whether the cleaning device is in working or non-working state. When the cleaning device is in working state, the first pipe 1 passes through the through hole 91, and the nozzle 11 is inside the conveying chamber 81. At this time, the entire conical cover 2 is inside the conveying chamber 81. When the cleaning device is in non-working state, the first pipe 1 disengages from the through hole 91, causing the nozzle 11 to exit the conveying chamber 81. At this time, the side wall of the conical cover 2 abuts against the edge of the through hole 91 to achieve sealing. The tip of the conical cover 2 is located outside the conveying chamber 81, while the bottom of the conical cover 2 is still located inside the conveying chamber 81. The conical cover 2 is partially located inside the conveying chamber 81.
[0040] Preferably, a sealing gasket can be laid on the side of the conical cover 2 to improve the sealing performance when the conical cover 2 blocks the through hole 91. In other embodiments, a sealing ring can be fitted only on the conical cover 2 to reduce manufacturing costs. The sealing ring should be positioned flush with the edge of the conical cover 2 and the through hole 91 to ensure that the sealing ring can abut against the edge of the through hole 91 and perform a sealing function.
[0041] Furthermore, the cleaning device also includes a drive assembly 4. The output end of the drive assembly 4 is connected to the first pipe 1, and the fixed end is connected to an external structure. The drive assembly 4 is used to drive the first pipe 1 to move along its own axial direction. The drive assembly 4 can be a rodless cylinder, including a cylinder barrel 41, a piston, a slider 42, and a guide rod 43. The extension direction of the guide rod 43 is parallel to the axial direction of the first pipe 1. The cylinder barrel 41 is connected to the external structure. The piston can move within the cylinder barrel 41 by compressed air. The movement of the piston is transmitted to the slider 42 through a coupling mechanism, and then the slider 42 can move on the guide rod 43. The slider 42 is connected to the first pipe 1, thereby driving the first pipe 1 to move along its own axial direction. Of course, in other embodiments, the drive assembly 4 can also be a rod cylinder or a motor, etc.
[0042] Preferably, the cleaning device further includes a connecting plate 5, one side of which is connected to the output end of the drive assembly 4, and the other side is connected to the outer wall of the first pipe 1. The connecting plate 5 is used to connect the slider 42 and the first pipe 1, and the connecting plate 5 can be welded to the first pipe 1 to improve the connection strength. The cleaning device also includes a support plate 6, which is fixed to the external structure, and the cylinder 41 is fixed to the external structure by connecting to the support plate 6.
[0043] The cleaning device also includes a sensing component. When the sealing component blocks the through hole 91, the sensing component sends a signal, and the drive component 4 stops driving the first pipe fitting 1. The sensing component includes a sensor. When the sealing component completes to block the through hole 91, the sensor senses the position of the sealing component and sends a positioning signal. At this time, the drive component 4 stops operating, ensuring that the drive component 4 only consumes energy during movement, reducing unnecessary wear and extending its service life. On the other hand, if the drive component 4 drives the first pipe fitting 1 out of the through hole 91 and the sensor does not send a positioning signal for a long time, it may indicate that the sealing component has fallen off. This allows the staff to quickly detect the abnormality and take remedial action, improving work efficiency.
[0044] In addition, the cleaning device also includes a second pipe 7 and a cleaning material tank. One end of the second pipe 7 is coaxially connected to the end of the first pipe 1 away from the nozzle 11, and the other end is connected to the outlet of the cleaning material tank. The cleaning material in the cleaning material tank can be transferred to the first pipe 1 through the second pipe 7 and then sprayed out by the nozzle 11.
[0045] Furthermore, the second fitting 7 is deformable; specifically, the second fitting 7 is made of a deformable material. Since the cleaning hopper is fixed in position, while the first fitting 1 is movable along its own axial direction, the second fitting 7, as a neutral component connecting the cleaning hopper and the first fitting 1, needs to adapt to the movement of the first fitting 1. Therefore, a deformable material is used to absorb the displacement and vibration of the first fitting 1, avoiding a rigid connection that could restrict the movement of the first fitting 1 or even cause it to break under stress, while also ensuring the stability of the cleaning hopper. Preferably, the second fitting 7 is a rubber hose. Of course, in other embodiments, the second fitting 7 can also be a corrugated pipe or a silicone tube.
[0046] The first pipe fitting 1 can be made of a rigid material to ensure movement stability and guarantee that the first pipe fitting 1 can accurately pass through the through hole 91 when moving along its own axial direction. Preferably, the first pipe fitting 1 is a galvanized pipe. Both the first pipe fitting 1 and the second pipe fitting 7 are conveying pipelines.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
