Description

Technical Field

[0001] The utility model relates to the field of cleaning of tobacco machinery and equipment, and particularly relates to a dust removal device. Background Art

[0002] The storage cabinet is a large key equipment in the cigarette making and silk production line, with a large number and frequent use in the production line. The storage cabinet is generally used to store the finished and semi-finished tobacco leaves, cut tobacco, tobacco stems, stemmed tobacco, etc. on the production line. The storage cabinet can adjust and balance the moisture content of the work-in-process to meet the preparation process requirements of tobacco leaves, cut tobacco, tobacco stems, and stemmed tobacco, which is crucial for ensuring the quality of tobacco leaves.

[0003] During the production of the storage cabinet, the tobacco leaves, cut tobacco, tobacco stems, and stemmed tobacco have the processes of entering the cabinet, storing, and leaving the cabinet. Among them, dust and material leakage are likely to occur during the processes of entering and leaving the cabinet, resulting in a certain amount of powder dust of tobacco leaves, cut tobacco, and tobacco stems distributed on the working surface of the bottom belt of the storage cabinet. With the reciprocating movement of the bottom belt of the storage cabinet, after a period of time, the dust will be scattered in large quantities on the non-working surface of the bottom belt of the storage cabinet, which is prone to breeding tobacco insects. In the prior art, a flexible dust suction air duct is used to connect a cleaning device for dust removal. Specifically, the suction port of the flexible dust suction air duct is aligned with the bottom belt, and the suction port reciprocates along the extension direction of the bottom belt to adsorb the dust on the bottom belt. However, in practical applications, the dust removal effect of using the flexible dust suction air duct for dust removal is not good. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of poor dust removal effect in the prior art. The utility model provides a dust removal device, which can improve the dust removal effect and the quality of products.

[0005] In order to solve the above technical problem of poor dust removal effect, an embodiment of the utility model discloses a dust removal device, including:

[0006] A first conveying pipeline extending along a first direction, the first direction being the flowing direction of the gas in the first conveying pipeline, and a plurality of air holes are arranged at intervals along the first direction on the first conveying pipeline, and the air holes are communicated with the inner cavity of the first conveying pipeline;

[0007] A support seat, on which a through hole penetrating the support seat along the first direction is provided, the first conveying pipeline is inserted into the through hole, and the support seat can reciprocally slide on the first conveying pipeline along the first direction;

[0008] A suction air duct, on which a suction port is provided, and an air flow channel communicated with the through hole is further provided in the suction air duct and the support seat. When the support seat reciprocally slides on the first conveying pipeline, the suction port can be sequentially communicated with each air hole through the air flow channel;

[0009] The first protective cover is arranged on one side of the support along the first direction. The first protective cover is made of deformable material. One end of the first protective cover is connected to the first conveying pipeline, and the other end of the first protective cover is connected to the support. The first protective cover covers all the air holes arranged on one side of the support along the first direction.

[0010] The second protective cover is arranged on the other side of the support along the second direction. The second direction is opposite to the first direction. The second protective cover is made of deformable material. One end of the second protective cover is connected to the first conveying pipeline, and the other end of the second protective cover is connected to the support. The second protective cover covers all the air holes arranged on one side of the support along the second direction.

[0011] With the above technical solution, when dust removal is required, the support can be driven to reciprocally slide along the extending direction of the first conveying pipeline to drive the suction port to move, so as to achieve dust removal. Using the above device to replace the flexible dust suction air duct in the prior art can avoid the deformation of the dust removal pipeline while the suction port moves, thus ensuring smooth air flow and improving the dust removal effect.

[0012] Furthermore, the dust removal device provided by the present utility model further includes two limit blocks, both of which are arranged on the outer wall of the first conveying pipeline. One limit block is arranged on one side of the support along the first direction, and the other limit block is arranged on the other side of the support along the second direction. The limit blocks are used to limit the sliding range of the support along the first direction and the second direction.

[0013] Furthermore, the dust removal device provided by the present utility model further includes: two limit switches, respectively arranged on the two limit blocks; a driving mechanism, connected to the support, for driving the support to move along the first direction or the second direction; a control unit, electrically connected to the limit switches and the driving mechanism respectively. When the support contacts the limit switch, the limit switch sends a signal to the control unit, and the driving mechanism drives the support to move in the reverse direction.

[0014] With the above technical solution, by setting the limit blocks to limit the movement range of the support, preventing the support from exceeding the preset position when moving along the first direction or the second direction, resulting in damage to the first protective cover or the second protective cover due to excessive traction. At the same time, under the limitation of the limit blocks, the support drives the suction air duct to reciprocally move within a preset range along the first direction or the second direction, which can effectively improve the cleaning effect and thus ensure the product quality.

[0015] Furthermore, the dust removal device provided by the present utility model further includes a negative pressure fan. The negative pressure fan is provided with an air inlet, and the air inlet is communicated with the end of the first conveying pipeline. The air inlet is used to provide a negative pressure air source to make an air flow flowing along the first direction generated in the first conveying pipeline.

[0016] Furthermore, the dust removal device provided by the utility model also includes a second conveying pipe, one end of the second conveying pipe is connected to the air inlet, and the other end of the second conveying pipe is connected to the end of the first conveying pipe. The second conveying pipe is curved and is used to change the flow direction of the airflow.

[0017] Furthermore, the dust removal device provided by the utility model also includes a dust brush, which is arranged outside the air suction port. The dust brush can be moved along the first direction or the second direction along with the air suction pipe under the drive of the driving mechanism.

[0018] By adopting the above technical solution, a negative pressure air source is provided by a negative pressure fan, so that the second conveying pipe and the first conveying pipe are connected to the suction pipe through the air holes to form a complete air flow channel. In combination with the dust brush outside the suction port, dust impurities can be better collected to improve the cleaning effect.

[0019] Furthermore, the support and the first protective sleeve, as well as the support and the second protective sleeve are connected via a throat clamp.

[0020] Furthermore, the first delivery pipeline and the first protective sleeve, as well as the first delivery pipeline and the second protective sleeve are connected via flanges.

[0021] Furthermore, an end cap is provided at the end of the first delivery pipeline along the second direction. By adopting the above technical solution, the air holes on the first delivery pipeline are fully covered by the first protective sleeve and the second protective sleeve in cooperation with the support, and one end of the first delivery pipeline is sealed by the end cap, thereby ensuring the sealing of the air flow channel and preventing dust and impurities from leaking.

[0022] Furthermore, the first conveying pipe, the support and the air suction pipe are all made of metal materials, and the first protective cover and the second protective cover are both accordion covers.

[0023] By adopting the above technical solution, the first conveying pipe can provide a certain supporting force for the first protective cover and the second protective cover to prevent the first conveying pipe from bending and deforming under the action of the gravity of the support, thereby preventing the support from sliding poorly on the first conveying pipe and reducing the dust removal effect.

[0034] To make the purpose, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0035] The storage cabinet is a large key equipment in cigarette making and wire production. The storage cabinet is crucial for balancing the moisture of the work-in-process. Therefore, cleaning the storage cabinet will have a great impact on product quality to a large extent. Due to the large number of storage cabinets, high height, and narrow space inside the bottom belt of the storage cabinet, the cleaning workload is very large and the labor intensity is very high. In the prior art, a flexible dust suction air duct is usually used to connect the cleaning device to dust the storage cabinet. However, in actual applications, there is a problem that the dust removal effect of using the flexible dust suction air duct is not good.

[0036] After exploration by the inventor, it is found that the main reason for the poor dust removal effect in the prior art is that during the dust removal process, the suction port of the flexible dust suction air duct needs to be aligned with the bottom belt and the suction port needs to reciprocate along the extension direction of the bottom belt to adsorb the dust on the bottom belt. During the reciprocating movement of the suction port, the flexible suction air duct is repeatedly bent, and it is very easy to be distorted and deformed, resulting in poor air flow. Moreover, dust impurities may accumulate at the bending place due to poor air flow, increasing the risk of blockage, which will lead to a decrease in suction and a poor dust removal effect. In addition, repeated bending is likely to cause cracks or damage to the flexible suction air duct, resulting in poor airtightness of the cleaning device. Dust impurities may leak out from the damaged place and return to the storage cabinet again, resulting in a great reduction in the cleaning effect. In addition, poor airtightness will also cause some air flow to pass through non-preset air flow channels, which will increase the burden on the motor and increase the loss. All of the above will cause the problem of poor dust removal effect of the cleaning device.

[0037] To solve the above technical problem of poor dust removal effect, an embodiment of the present utility model discloses a dust removal device. Referring to Figure 1 and Figure 2 , the dust removal device provided by the present utility model includes a first conveying pipeline 1, a support 2, a suction air duct 3, a first protective sleeve 4, and a second protective sleeve 5. Among them, the first conveying pipeline 1, the support 2, and the suction air duct 3 are all made of rigid materials. The first conveying pipeline 1 is along the first direction (such as Figure 1extends in the X1 direction shown in the figure. The first direction is the flow direction of the gas in the first conveying pipe 1. A plurality of air holes 11 are provided on the first conveying pipe 1 at intervals along the first direction, and the air holes 11 communicate with the inner cavity of the first conveying pipe 1. Refer to Figure 3 , a through hole 21 penetrating the support 2 along the first direction is provided on the support 2. The first conveying pipe 1 is inserted into the through hole 21, and the support 2 can slide reciprocally on the first conveying pipe 1 along the first direction. An air suction port 31 is provided on the air suction pipe 3, and an air flow channel 22 communicating with the through hole 21 is further provided in the air suction pipe 3 and the support 2. When the support 2 slides reciprocally on the first conveying pipe 1, the air suction port 31 can communicate with each air hole 11 in sequence through the air flow channel 22. The first protective sleeve 4 is arranged on one side of the support 2 along the first direction. The first protective sleeve 4 is made of a deformable material. One end of the first protective sleeve 4 is connected to the first conveying pipe 1, and the other end of the first protective sleeve 4 is connected to the support 2. The first protective sleeve 4 covers all the air holes 11 arranged on one side of the support 2 along the first direction. The second protective sleeve 5 is arranged on the other side of the support 2 along the second direction (such as Figure 1 the X2 direction shown in the figure). The second direction is opposite to the first direction. The second protective sleeve 5 is made of a deformable material. One end of the second protective sleeve 5 is connected to the first conveying pipe 1, and the other end of the second protective sleeve 5 is connected to the support 2. The second protective sleeve 5 covers all the air holes 11 arranged on the other side of the support 2 along the second direction.

[0038] Adopting the above technical solution, when dust removal is required, a negative pressure gas flowing in the first direction is introduced into the first conveying pipe 1, and the flow direction of the air flow is as shown by the arrow in Figure 2 . Since the first protective sleeve 4 and the second protective sleeve 5 cover all the air holes 11 exposed outside the support 2, the negative pressure gas can only pass through the air holes 11 inserted into the through hole 21 and the air flow channel 22, and finally generate a negative pressure at the air suction port 31. Subsequently, by driving the support 2 to slide reciprocally along the extending direction of the first conveying pipe 1, the air suction port 31 can be driven to move along the extending direction of the bottom belt of the storage cabinet, thereby realizing dust removal. Since the first conveying pipe 1, the support 2 and the air suction pipe 3 are all made of rigid materials, such as stainless steel, aluminum alloy, etc., the present application can avoid the deformation of the dust removal pipe while realizing the movement of the air suction port 31, thereby ensuring smooth air flow and improving the dust removal effect.

[0039] Exemplarily, the diameter of the air hole 11 can be 4 mm, and the center distance between two adjacent air holes 11 can be 8 mm. The punching range on the first conveying pipe 1 can be adjusted appropriately. Exemplarily, no air holes 11 are provided within 50 mm at both ends of the first conveying pipe 1.

[0040] Furthermore, refer to Figure 2, the dust removal device provided by the present utility model further includes two limit blocks 7, and both of the two limit blocks 7 are arranged on the outer wall of the first conveying pipeline 1. One of the limit blocks 7 is arranged on one side of the support 2 along the first direction. When the support 2 contacts the limit block 7, the limit block 7 can block the support 2 from continuing to move along the X1 direction. The other limit block 7 is arranged on the other side of the support 2 along the second direction. When the support 2 contacts the limit block 7, the limit block 7 can block the support 2 from continuing to move along the X2 direction. By setting the limit blocks 7 to limit the sliding range of the support 2 along the first direction and the second direction, it is possible to prevent the support 2 from exceeding the preset position when moving along the first direction or the second direction, thereby avoiding the damage of the first protective sleeve or the second protective sleeve due to excessive traction.

[0041] Further, referring to Figure 2 , the dust removal device provided by the present utility model further includes two limit switches 71, a driving mechanism and a control unit. Among them, the two limit switches 71 are respectively arranged on the two limit blocks 7. The driving mechanism is connected to the support 2 and is used to drive the support 2 to move along the first direction or the second direction. The control unit is electrically connected to the limit switches 71 and the driving mechanism respectively. When the support 2 contacts the limit switch 71, the limit switch 71 sends a signal to the control unit, and the driving mechanism drives the support 2 to move in the reverse direction. By adopting the above technical solution, the automatic control of the movement of the suction pipe 3 can be realized.

[0042] Further, referring to Figure 1 , the dust removal device provided by the present utility model further includes a negative pressure fan 8. The negative pressure fan 8 is provided with an air inlet, and the air inlet is connected to the end of the first conveying pipeline 1. The air inlet is used to provide a negative pressure air source so as to generate an air flow flowing along the first direction in the first conveying pipeline 1.

[0043] Further, referring to Figure 1 and Figure 2 , the dust removal device provided by the present utility model further includes a second conveying pipeline 6. One end of the second conveying pipeline 6 is connected to the air inlet, and the other end of the second conveying pipeline 6 is connected to the end of the first conveying pipeline 1. The second conveying pipeline 6 is bent and is used to change the flow direction of the air flow.

[0044] Further, referring to Figure 1 , the dust removal device provided by the present utility model further includes a dust-raising brush 9. The dust-raising brush 9 is arranged outside the air suction port 31, and the bristles on the dust-raising brush 9 can contact the bottom belt of the storage cabinet. The dust-raising brush 9 can move along the first direction or the second direction together with the suction pipe 3 under the drive of the drive mechanism. During the movement of the dust-raising brush 9, the dust-raising brush 9 can brush off the dust impurities scattered on the bottom belt of the storage cabinet, and then the dust impurities brushed off are adsorbed by the air suction port 31. By setting the dust-raising brush 9 in this application, the cleaning effect can be improved.

[0045] Further, a dust collection hood fixedly connected to the air suction port 31 is provided outside the dust-raising brush 9. Specifically, the dust collection hood can cover one-half or two-thirds of the upper area of the dust-raising brush 9. The lower part of the dust-raising brush 9 can brush off the dust and impurities scattered on the bottom belt of the storage cabinet, and the dust collection hood can gather the dust and impurities lifted with the movement of the brush, preventing the dust from spreading into the working environment. At the same time, the dust collection hood can ensure that the dust and impurities brushed up by the dust-raising brush 9 are completely adsorbed by the air suction port 31. By setting the dust collection hood in this application, the cleaning effect can be greatly guaranteed.

[0046] Further, both between the support 2 and the first protective sleeve 4 and between the support 2 and the second protective sleeve 5 are connected by hose clamps.

[0047] Further, both between the first conveying pipeline 1 and the first protective sleeve 4 and between the first conveying pipeline 1 and the second protective sleeve 5 are connected by flanges.

[0048] Exemplarily, the thickness of the flange can be 5 millimeters, and the flange can be connected by bolts.

[0049] Further, an end cap is provided at the end of the first conveying pipeline 1 along the second direction.

[0050] By adopting the above technical solution, by providing an end cap at the end of the first conveying pipeline 1 far from the negative pressure fan 8 and using the end cap to seal the end of the first conveying pipeline 1, the airtightness of the air flow channel 22 can be ensured, thereby avoiding the leakage of dust and impurities.

[0051] Further, the first conveying pipeline 1, the support 2 and the air suction pipe 3 are all made of metal materials, and the first protective sleeve 4 and the second protective sleeve 5 are both bellows sleeves. Exemplarily, the wall thickness of the first conveying pipeline 1, the support 2 and the air suction pipe 3 can be 1 millimeter, and the materials of the first conveying pipeline 1, the support 2 and the air suction pipe 3 can be stainless steel.

[0052] The dust removal device provided by the present utility model effectively solves the problem of poor cleaning effect of the storage cabinet, realizes efficient cleaning in a narrow space, thereby eliminating the risk of breeding eggs, ensuring the cleanliness of the environment during the production and wire-making process, reducing the labor intensity of manual cleaning, and ensuring the product quality.
