Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a filter rod unclogging device. Background Technology

[0002] In the cigarette production process of the tobacco industry, the filter rod pneumatic conveying system plays a crucial role. Filter rods are transported to the filter rod receiver via a conveying pipe. As the mainstream equipment in the filter rod pneumatic conveying system, the operational stability of the filter rod receiver directly affects the efficiency and quality of cigarette production. During production, when the filter rod receiver becomes clogged, workers often need to disconnect the filter rod conveying pipe to remove the remaining filter rods inside, allowing for smooth restart of the machine.

[0003] However, the frequent and arbitrary insertion and removal of filter rod delivery pipes by staff caused excessive displacement of the pipes, resulting in malfunctions such as pipe bending, ceiling damage, damage to detection devices, and damage to quick connectors in the filter rod receiver. This not only seriously affected the normal cigarette production process, causing production interruptions and reduced efficiency, but also negatively impacted the standardization of the workshop working environment and posed a risk of potential safety hazards.

[0004] Therefore, there is an urgent need to develop a filter rod unclogging device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a filter rod unclogging device, which improves the standardization of filter rod unclogging operation, reduces the frequency of filter rod insertion and removal in the filter rod conveying pipeline, reduces pipeline bending and component damage, lowers equipment failure rate, and eliminates safety hazards.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A filter rod unclogging device, comprising:

[0008] A channel base includes a base body and an opening / closing part. The base body has an upper channel, a lower channel, and a first through groove in the middle section. The opening / closing part has a second through groove corresponding to the first through groove and is closable over the first through groove. When the opening / closing part is closed, the first through groove and the second through groove form the middle channel. The upper channel, the middle channel, and the lower channel are sequentially connected to form a filter rod channel, which is used to connect a filter rod conveying pipe and a filter rod receiver. When the opening / closing part is open, the opening of the first through groove is exposed to discharge blocked filter rods.

[0009] The detection component is used to detect the state of the filter rods within the filter rod channel;

[0010] The ejection assembly includes a first driving member and a guide block. The first driving member is mounted on the base body, and the output end of the first driving member is connected to the guide block for driving the guide block through the base body and into the first through groove, so that the filter rod is discharged through the opening of the first through groove.

[0011] Furthermore, the guide block has a guide surface on the side near the base body, and the guide surface gradually slopes downward toward the opening of the first through slot.

[0012] Furthermore, the guiding surface is a hyperbolic paraboloid, with the concave side of the hyperbolic paraboloid facing upwards.

[0013] Furthermore, the first driving component includes a fixed sleeve, a push rod, and an elastic element. The fixed sleeve is mounted on the base body. The push rod slides through the fixed sleeve in a direction close to or away from the channel base. A limiting groove is formed on the side wall of the fixed sleeve. The limiting groove extends axially along the fixed sleeve, and the end of the limiting groove close to the base body bends away from the base body. The push rod is provided with a limiting part, which is slidably connected to the limiting groove and can abut against the bent end of the limiting groove. The elastic element is disposed between the push rod and the fixed sleeve to keep the push rod tending away from the base body. The guide block is disposed at the end of the push rod close to the base body.

[0014] Furthermore, one end of the opening / closing part is hinged to the base body, and the opening / closing part is detachably connected to the base body.

[0015] Furthermore, the opening and closing part is magnetically connected to the base body.

[0016] Furthermore, the detection component includes a reflector and a first detection element. The reflector is installed on the side of the opening and closing portion opposite to the second through slot. The first detection element is used to transmit and receive detection signals. A first detection hole is provided on the base body, and a first reflection hole is provided on the opening and closing portion opposite to the first detection hole. The detection signal emitted by the first detection element can travel back and forth between the reflector and the first detection element through the first detection hole and the first reflection hole.

[0017] Furthermore, the detection assembly also includes a second detection element, which is used to transmit and receive detection signals. The second detection element is spaced apart from the first detection element along the axial direction of the filter rod channel. The base body is also provided with a second detection hole, and the opening and closing part is provided with a second reflection hole opposite to the second detection hole. The detection signal emitted by the second detection element can travel back and forth between the reflector and the second detection element through the second detection hole and the second reflection hole.

[0018] Furthermore, the filter rod unclogging device also includes a clamping assembly, which includes a second driving member and a clamping member. The second driving member is mounted on the base body, and the clamping member is disposed at the output end of the second driving member. The second driving member is used to drive the clamping member through the base body into the lower channel, so that the clamping member and the side wall of the lower channel jointly clamp the filter rod.

[0019] Furthermore, the side of the clamping member closest to the base body is adapted to the shape of the filter rod.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a filter rod unclogging device, including a channel base, a detection component, and an ejection component. The channel base includes a base body and an opening / closing part. The base body has an upper channel, a lower channel, and a first through groove in the middle section. The opening / closing part has a second through groove corresponding to the first through groove and can be opened and closed to cover the first through groove. When the opening / closing part is closed, the first through groove and the second through groove form the middle channel. The upper channel, the middle channel, and the lower channel are sequentially connected to form a filter rod channel, which is used to connect a filter rod conveying pipe and a filter rod receiver. When the opening / closing part is open, the opening of the first through groove is exposed to discharge the clogged filter rod. The detection component is used to detect the status of the filter rod in the filter rod channel. The ejection component includes a first driving member and a guide block. The first driving member is installed on the base body, and the output end of the first driving member is drivenly connected to the guide block to drive the guide block through the base body and into the first through groove, so that the filter rod is discharged through the opening of the first through groove. When the detection component detects a blockage in the filter rod channel, the filter rod receiver stops working. The operator can then open the opening mechanism, and the first drive component drives the guide block into the first through slot, pushing the blocked filter rod out from the opening of the first through slot. Other filter rods above the blocked filter rod will naturally exit from the opening of the first through slot during their descent, either due to gravity or collision with the guide block. This empties the remaining filter rods in the filter rod delivery pipe, preparing the filter rod receiver for restart and preventing re-blockage after restarting. This device improves the standardization of filter rod unblocking operations, avoids frequent and arbitrary insertion and removal of the filter rod delivery pipe by operators, effectively reduces the frequency of insertion and removal, minimizes pipe bending and component damage, lowers equipment failure rates, and eliminates potential production safety hazards.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figures 1-6As shown, this embodiment provides a filter rod unclogging device, disposed between the filter rod conveying pipe 100 and the filter rod receiver 200, for cleaning clogged filter rods. The filter rod unclogging device includes a channel base 1, a detection component 2, and an ejection component 3. The channel base 1 includes a base body 11 and an opening / closing part 12. The base body 11 has an upper channel, a lower channel, and a first through groove 111 in the middle section. The opening / closing part 12 has a second through groove 121 corresponding to the first through groove 111 and is closable over the first through groove 111. When the opening / closing part 12 is closed, the first through groove 111 and the second through groove 121 form the middle channel, the upper... The first section channel, the middle section channel, and the lower section channel are connected in sequence to form a filter rod channel, which is used to connect the filter rod conveying pipe 100 and the filter rod receiver 200. When the opening and closing part 12 is opened, the opening of the first through groove 111 is exposed to discharge the blocked filter rod. The detection component 2 is used to detect the status of the filter rod in the filter rod channel. The ejection component 3 includes a first driving member and a guide block 31. The first driving member is installed on the base body 11, and the output end of the first driving member is connected to the guide block 31. The first driving member can drive the guide block 31 through the base body 11 and into the first through groove 111 so that the filter rod is discharged through the opening of the first through groove 111.

[0040] When the detection component 2 detects a filter rod blockage in the filter rod channel, the filter rod receiver 200 stops working. The operator can open the opening and closing part 12, and the first driving component drives the guide block 31 into the first through groove 111, pushing the blocked filter rod out from the opening of the first through groove 111. Other filter rods above the blocked filter rod can be naturally discharged from the opening of the first through groove 111 during the falling process under the action of gravity or collision with the guide block 31, thereby emptying the remaining filter rods in the filter rod conveying pipe 100, preparing for the restart of the filter rod receiver 200, and avoiding re-blockage after restarting. The above-mentioned device cleans the blocked filter rods, improves the standardization of the filter rod unblocking operation, avoids the operator from randomly and frequently inserting and removing the filter rod conveying pipe 100, effectively reduces the frequency of insertion and removal of the filter rod conveying pipe 100, reduces pipe bending and component damage, reduces equipment failure rate, and eliminates production safety hazards.

[0041] like Figure 3 and Figure 5 As shown, the guide block 31 is further provided with a guide surface 311 on the side near the base body 11. The guide surface 311 is used to contact the falling filter rod. The guide surface 311 gradually tilts from top to bottom towards the opening of the first through groove 111. When the filter rod falls and collides with the guide surface 311, the guide surface 311 guides the filter rod to move towards the opening of the first through groove 111, so that it can be discharged more smoothly and avoid the filter rod from accumulating and clogging in the first through groove 111.

[0042] Furthermore, the guide surface 311 is a hyperbolic paraboloid with the concave side facing upwards, which can more accurately guide the movement trajectory of the filter rod, enabling the filter rod to reach the preset recycling position and making the movement trajectory of the filter rod more stable, avoiding the filter rod from rebounding or jumping during the discharge process, facilitating the collection of waste filter rods and reducing the amount of recycling work.

[0043] In this embodiment, the first driving component includes a fixed sleeve 32, a push rod 33, and an elastic element. The fixed sleeve 32 is mounted on the base body 11. The push rod 33 slides through the fixed sleeve 32 in a direction close to or away from the channel base 1. A limiting groove 321 is formed on the side wall of the fixed sleeve 32. The limiting groove 321 extends axially along the fixed sleeve 32, and the end of the limiting groove 321 close to the base body 11 bends away from the base body 11. A limiting part 331 is provided on the push rod 33. The limiting part 331 is slidably connected to the limiting groove 321 and can abut against the bent end of the limiting groove 321. The elastic element is disposed between the push rod 33 and the fixed sleeve 32 to keep the push rod 33 tending to move away from the base body 11. A guide block 31 is disposed at the end of the push rod 33 close to the base body 11. The first driving component has a simple and practical structure, low cost, and is easy to install and maintain. It can achieve reliable driving and positioning functions. The fixed sleeve 32 is mounted on the base body 11, and the push rod 33 is slidably connected to the fixed sleeve 32, providing stable support and guidance for the push rod 33 to drive the guide block 31 to move towards or away from the channel base 1. The limiting groove 321 extends axially along the fixed sleeve 32, and the limiting component keeps the push rod 33 tending to move away from the base body 11. When the filter rod is transported normally, the limiting part 331 abuts against the filter rod under the action of the limiting component. At the end of the limiting groove 321 away from the base body 11, the guide block 31 is kept away from the filter rod channel to ensure the normal passage of the filter rod. When the filter rod is blocked, the operator pushes the push rod 33 towards the base body 11 to push out the blocked filter rod. When the limiting part 331 reaches the bend of the limiting groove 321, the push rod 33 is rotated so that the limiting part 331 enters the bend end. Under the action of the limiting member, the limiting part 331 abuts against the bend end, so that the guide block 31 can be kept in an effective working position, thereby guiding the filter rod falling from above to be discharged.

[0044] Furthermore, a handle 34 is provided at the end of the push rod 33 away from the guide block 31 to facilitate the pusher to push and rotate the push rod 33.

[0045] In other embodiments, the first driving element includes, but is not limited to, a motor, a cylinder, or a hydraulic cylinder, and is not limited thereto.

[0046] like Figure 2 and Figure 3As shown, one end of the opening and closing part 12 is hinged to the base body 11. The opening and closing part 12 can rotate easily around the hinge point and can be opened or closed at any time according to actual needs. The operator can easily adjust the state of the opening and closing part 12 and flexibly adjust the opening angle when space is limited. The opening and closing part 12 is detachably connected to the base body 11. When the filter rod is transported normally, the opening and closing part 12 can be stably connected to the base body 11. When the filter rod is blocked, the opening and closing part 12 can be easily separated from the base body 11 to expose the opening of the first through groove 111.

[0047] In this embodiment, the opening / closing part 12 is magnetically connected to the base body 11. When closed, the connection between the opening / closing part 12 and the base body 11 is stable. When it needs to be opened, the operator only needs to apply a certain external force with one hand to overcome the magnetic force, and the opening / closing part 12 can be easily separated, which further improves the convenience of operation and helps guide the operator to follow the operating procedures. Moreover, the magnetic connection method does not have too many mechanical parts, which reduces the wear between parts, increases the service life of the connection structure, and reduces the maintenance frequency.

[0048] In other embodiments, the opening / closing portion 12 and the base body 11 may also be snap-fitted or pin-fitted, which is not limited here.

[0049] like Figures 2-4 As shown, the detection component 2 includes a reflector 21 and a first detection element 22. The reflector 21 is installed on the side of the opening and closing part 12 opposite to the second through groove 121. The first detection element 22 is used to transmit and receive detection signals. A first detection hole 112 is provided on the base body 11, and a first reflection hole 122 opposite to the first detection hole 112 is provided on the opening and closing part 12. The detection signal emitted by the first detection element 22 can travel back and forth between the reflector 21 and the first detection element 22 through the first detection hole 112 and the first reflection hole 122. The first detection element 22 transmits and receives detection signals through the first detection hole 112 and the first reflection hole 122, enabling it to travel back and forth between the reflector 21. When the filter rod is being transported normally in the channel, the detection signal will not be blocked for a long time and can travel back and forth intermittently between the reflector 21 and the first detection element 22. Once the filter rod becomes blocked, the detection signal path will be blocked. If the first detection element 22 cannot receive the signal reflected by the reflector 21, it will issue a filter rod blockage signal so that the staff can carry out maintenance. The first detection element 22 sends and receives signals by reflecting the signal through the reflector 21. The installation accuracy requirement of the reflector 21 is low, which makes the detection component 2 simple in structure, easy to install, and highly reliable.

[0050] In other embodiments, the detection component 2 includes a first detection element 22 and a first receiver. The first receiver is installed on the side of the opening and closing portion 12 away from the second through groove 121. The first detection element 22 is used to emit a detection signal. A first detection hole 112 is provided on the base body 11, and a first receiving hole opposite to the first detection hole 112 is provided on the opening and closing portion 12. The detection signal emitted by the first detection element 22 can be received by the first receiver through the first detection hole 112 and the first receiving hole, thereby detecting whether the filter rod in the filter rod channel is blocked.

[0051] Furthermore, the detection component 2 also includes a second detection element 23, which is used to transmit and receive detection signals. The second detection element 23 is spaced apart from the first detection element 22 along the axial direction of the filter rod channel. The base body 11 is also provided with a second detection hole 113, and the opening and closing part 12 is provided with a second reflection hole 123 opposite to the second detection hole 113. The detection signal emitted by the second detection element 23 can travel back and forth between the reflector plate 21 and the second detection element 23 through the second detection hole 113 and the second reflection hole 123. By using the first detection element 22 and the second detection element 23, which are spaced apart along the axial direction of the filter rod channel, the filter rods in the filter rod channel can be detected. This not only ensures the accuracy and reliability of the detection of filter rod blockage, but also allows the speed of the filter rod to be calculated based on the detected signal time difference. This enables the monitoring of the filter rod transportation speed, which helps to detect speed abnormalities in the filter rod transportation process in a timely manner, so as to adjust the transportation parameters and ensure production efficiency and product quality.

[0052] Similarly, the detection component 2 may also include a second detection element 23 and a second receiver. The second detection element 23 is spaced apart from the first detection element 22 along the axial direction of the filter rod channel. The second receiver is installed on the side of the opening and closing part 12 away from the second through groove 121. The second detection element 23 is used to transmit detection signals. A second detection hole 113 is provided on the base body 11, and a second receiving hole opposite to the second detection hole 113 is provided on the opening and closing part 12. The detection signal emitted by the second detection element 23 can be received by the second receiver through the second detection hole 113 and the second receiving hole. This will not be elaborated here.

[0053] Optionally, the first detection element 22 and the second detection element 23 may include, but are not limited to, photoelectric sensors, ultrasonic sensors or laser sensors. Correspondingly, the reflector 21 may be a mirror reflector 21 to reflect light, a metal reflector 21 to reflect ultrasonic waves or a pyramidal reflector 21 to reflect lasers, and no limitation is made here.

[0054] Furthermore, the first detection element 22 and / or the second detection element 23 are connected to the filter rod receiver 200 via signal. When the first detection element 22 and / or the second detection element 23 detects that the filter rod is blocked or the filter rod is moving too slowly, the filter rod receiver 200 will automatically stop after receiving the signal and can send a signal to remind the staff to clear the blockage, so as to avoid affecting normal production and improve the automation level of the filter rod transportation system.

[0055] like Figure 3 and Figure 6 As shown, in this embodiment, the filter rod unclogging device further includes a clamping assembly 4. The clamping assembly 4 includes a second driving member 41 and a clamping member 42. The second driving member 41 is installed on the base body 11, and the clamping member 42 is disposed at the output end of the second driving member 41. The second driving member 41 is used to drive the clamping member 42 through the base body 11 into the lower channel so that the clamping member 42 and the side wall of the lower channel jointly clamp the filter rod. When the filter rod is clogged, the second driving member 41 drives the clamping member 42 into the lower channel to clamp the filter rod, thereby preventing the clogged filter rod from entering the filter rod receiver 200 under the action of thrust, thus avoiding damage to the filter rod receiver 200. Blocking the clogged filter rod in the channel base 1 makes it easier for the staff to unclogging through the first through groove 111, greatly reducing the difficulty of unclogging.

[0056] Optionally, the second drive component 41 may include, but is not limited to, a pneumatic cylinder or a hydraulic cylinder, which is not limited here.

[0057] Furthermore, the second driving element 41 is signal-connected to the first detection element 22 and / or the second detection element 23. When the first detection element 22 and / or the second detection element 23 detects that the filter rod is blocked or the filter rod moves too slowly, the second driving element 41 receives the signal and promptly drives the clamping element 42 to clamp the filter rod, thereby improving the response speed and automation level of the filter rod unblocking device.

[0058] like Figure 6 As shown, in this embodiment, the side of the clamping member 42 near the base body 11 is adapted to the shape of the filter rod, so as to stabilize the filter rod and reduce the clamping deformation of the filter rod, which is beneficial to improving the recycling rate of the filter rod.

[0059] Optionally, such as Figure 1 As shown, the filter rod unclogging device also includes a quick-connect connector 5, which is used to connect the filter rod channel and the filter rod conveying pipe 100. The quick-connect connector 5 is easy to insert and remove, which can improve the assembly efficiency of the filter rod unclogging device and the filter rod conveying pipe 100. When the filter rod unclogging device fails, it can be quickly disassembled and replaced.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
