Description

Technical Field

[0001] This utility model relates to the field of tobacco processing machinery technology, and in particular to a tobacco feeder with a function of preventing material blockage at the feed inlet. Background Technology

[0002] The feeder is a commonly used conveying device in tobacco production. The storage bin, located at the bottom of the feeder, is used to accumulate materials. The elevator, installed at an angle, is used to lift the materials to a higher position.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The following is combined Figures 1 to 2 The present invention provides a detailed description of the tobacco feeder with the function of preventing material blockage at the feed inlet, through specific embodiments and application scenarios.

[0037] like Figure 1 and Figure 2 As shown, this embodiment provides a tobacco feeder with a function to prevent material blockage at the feed inlet, including: a storage bin 1, a hoist 2, a feeding assembly 3, a detection assembly 4, and a blockage clearing assembly 5.

[0038] Storage hopper 1 is connected to one end of elevator 2, and the other end of elevator 2 is connected to unloading assembly 3.

[0039] The feeding component 3 is funnel-shaped and forms a feeding port 31 that is wider at the top and narrower at the bottom. The detection component 4 is located on the feeding component 3 and inside the feeding port 31. The unblocking component 5 is movably located on the upper side of the feeding component 3.

[0040] The unblocking component 5 moves between a first position and a second position. When the unblocking component 5 is in the first position, it extends into the discharge port 31 and is positioned opposite to the detection component 4. The unblocking component 5 is used to unblock the material in the discharge port 31. When the unblocking component 5 is in the second position, it is located outside the discharge port 31.

[0041] The detection component 4 is used to detect whether there is a blockage in the feeding component 3.

[0042] Understandably, in the tobacco feeding device, the storage bin 1 is used to buffer the tobacco leaves and shredded tobacco conveyed in the previous process. The storage bin stores a certain amount of material and conveys it to the elevator 2 via a conveyor belt. The elevator 2's lifting belt further conveys the material to the discharge port 31 of the feeding component 3. The material is then conveyed to the next device after passing through the discharge port 31.

[0043] The inner cavity formed by the feeding assembly 3 is funnel-shaped. Due to the top-widening and bottom-narrowing shape of the feeding port 31, after the material is fed into the feeding port 31 by the elevator 2, the channel inside the feeding port 31 gradually narrows, causing the material to be gathered as it passes through the feeding port 31. The material conveying volume increases instantaneously, making it easy for the material to accumulate and block the feeding port 31, resulting in poor conveying. The detection assembly 4 can detect the accumulation of material when the blockage just begins to occur. The detection assembly 4 feeds back the blockage signal to the unblocking assembly 5. The unblocking assembly 5 moves to the first position and extends into the feeding port 31 to unblock the blockage. After the unblocking work is completed, the detection assembly 4 can no longer detect the blockage signal, and the unblocking assembly 5 moves to the second position, located outside the feeding port 31, and the material conveying inside the feeding port 31 continues. The switching of the position of the unblocking component 5 ensures that when the discharge port 31 needs unblocking, the unblocking component 5 is used to clear the accumulated material, and when the discharge port 31 does not need unblocking, the unblocking component 5 automatically exits the discharge port 31, thus avoiding interference with the material conveying.

[0044] Specifically, the detection component 4 can be a photoelectric sensor or an ultrasonic sensor. The unblocking component 5 can agitate and unblock the material in the feed port 31, or it can unblock the material by increasing the material conveying speed.

[0045] The tobacco feeder with anti-clogging function at the feeding port provided by this utility model has a detection component 4 and a clearing component 5 set in the feeding component 3. The detection component 4 can detect the blockage of the material in the feeding port 31 in real time. When the material in the feeding port 31 is blocked, the clearing component 5 is moved to extend into the feeding port 31 to clear the blockage. After the blockage in the feeding port 31 is cleared, the clearing component 5 is moved to the outside of the feeding port 31 without interfering with the material conveying. This allows the material blockage in the feeding port 31 to be cleared in a timely manner, avoiding obstacles to material conveying caused by the blockage of the feeding port 31, improving the reliability of material conveying at the feeding port 31, and ensuring the stability of tobacco production quality.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the detection component 4 in this embodiment includes a mounting bracket 41 and a photoelectric sensor 42.

[0047] Mounting bracket 41 is located on the inner wall of unloading assembly 3, and photoelectric sensor 42 is rotatably mounted on mounting bracket 41.

[0048] It is understood that the mounting bracket 41 in this embodiment is detachably connected to the inner wall of the feeding assembly 3, and the photoelectric sensor 42 is connected to the mounting bracket 41 through a rotating structure. Specifically, the photoelectric sensor 42 can be connected to the mounting bracket 41 through a hinge or through a rotating shaft.

[0049] In this embodiment, the photoelectric sensor 42 can rotate relative to the mounting bracket 41. By adjusting the mounting angle of the photoelectric sensor 42 relative to the feeding assembly 3, the collection area of ​​the photoelectric sensor 42 can be adjusted, thereby expanding the collection area of ​​the photoelectric sensor 42, so that all materials in the feeding port 31 can be detected, and the detection range of material accumulation can be expanded.

[0050] The photoelectric sensor 42 in this embodiment can perform detection without contacting the material, and has high sensitivity and short response time, which can improve the efficiency of detecting material blockage.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, the photoelectric sensor 42 in this embodiment includes a phototube.

[0052] Understandably, phototubes utilize the photoelectric effect to convert light signals into electrical signals, providing effective electrical signals for collecting material blockage signals.

[0053] Optionally, the phototube in this embodiment can be a photodiode or a photomultiplier tube.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the photoelectric sensor 42 in this embodiment includes a photoelectric switch.

[0055] Understandably, the photoelectric switch in this embodiment has a short response time, high resolution, and strong anti-interference capability, and can accurately collect the blockage signal of the material in the feed port 31.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the detection component 4 in this embodiment is provided in multiple ways, and the multiple detection components 4 are arranged at intervals on the inner wall of the feeding component 3.

[0057] Understandably, in order to detect blockages at different locations within the discharge port 31, multiple detection components 4 can be installed within the discharge port 31. These multiple detection components 4 are arranged sequentially at different locations. By analyzing the blockage signals collected by each detection component 4, the blockage path and the location of the blockage center within the discharge port 31 can be determined, enabling operators to carry out targeted clearing and unblocking.

[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, the detection component 4 in this embodiment has two parts.

[0059] The detection component 4 includes a mounting bracket 41 and a photoelectric tube. The two mounting brackets 41 are arranged opposite each other on both sides of the inner wall of the unloading component 3, and the photoelectric tube is mounted on the mounting bracket 41.

[0060] Understandably, a through-beam phototube is a photoelectric detection device, mainly composed of a transmitter and a receiver. The transmitter emits a light beam, and when material blocks this light beam, the receiver detects the change in light intensity and outputs an electrical signal to trigger the corresponding control action. Two through-beam phototubes are placed opposite each other in the feed port 31, and the through-beam paths of the two phototubes pass through the material falling area. When the material is blocked, the detection path of the through-beam phototubes is blocked, and the through-beam phototubes send a blockage signal to the controller.

[0061] This embodiment improves the stability of detection by using two opposing phototubes. The paired arrangement reduces interference from other ambient light sources and improves the accuracy of material blockage detection.

[0062] In some embodiments, such as Figure 1 As shown, the unblocking component 5 in this embodiment includes a nozzle 51 and a moving rod 52.

[0063] The movable rod 52 is vertically mounted on the steel beam 21 of the hoist 2, and the movable rod 52 moves between a first position and a second position.

[0064] The nozzle 51 is located on the moving rod 52 and is used to blow air into the material in the feed port 31.

[0065] Understandably, when material blockage occurs in the feed inlet 31, it is detected in time by the detection component 4. At this time, the blockage is minor and can be treated by blowing air into the blocked part of the material using the nozzle 51, which can restore the material flow.

[0066] Specifically, the nozzle 51 can continuously blow air onto the material, or blow air onto the material intermittently, or blow air onto the material at any time as needed, and adjust the blowing duration as required.

[0067] The movable lever 52 is used to lift or lower relative to the discharge port 31. Specifically, the movable lever 52 can be lifted or lowered using a telescopic lever or a driver.

[0068] In this embodiment, a nozzle 51 and a moving rod 52 are set in the unblocking component 5. The position of the nozzle 51 is switched by the lifting and lowering movement of the moving rod 52. When the material in the discharge port 31 is blocked, the unblocking operation is performed by blowing air, which conveniently achieves the unblocking effect of minor blockage.

[0069] In some embodiments, such as Figure 1As shown, the unblocking component 5 in this embodiment also includes a compressed air source and a control valve.

[0070] The compressed air source is connected to the nozzle 51 through a pipeline, and the control valve is located on the pipeline between the compressed air source and the nozzle 51.

[0071] Understandably, the compressed air source provides a stable and continuous air supply to the nozzle 51. The compressed gas is ejected from the nozzle 51 to blow air onto the material. The opening and closing of the control valve can control the blowing and stopping of the nozzle 51.

[0072] The compressed air source can be compressed air, and the control valve can be a manual control valve, or an electric or pneumatic control valve.

[0073] In this embodiment, by setting a compressed air source and a control valve in the unblocking component 5, the compressed air source provides compressed gas to the nozzle 51, and the control valve can also be used to control the start and stop of the nozzle 51, thus realizing a flexible adjustment function.

[0074] In some embodiments, such as Figure 2 As shown, the unblocking component 5 in this embodiment includes a toggle lever 53 and a lifting seat 54.

[0075] The lifting seat 54 is movably mounted on the steel beam 21 of the hoist 2, and the lifting seat 54 moves between a first position and a second position.

[0076] The lever 53 is rotatably mounted on the lifting seat 54 and is used to move the material in the discharge port 31.

[0077] Understandably, when material blockage occurs in the feed inlet 31, it is detected in time by the detection component 4. At this time, the blockage is minor and can be resolved by using the toggle lever 53 to move the blocked part of the material, thus restoring the material flow.

[0078] The lifting seat 54 is used to lift relative to the discharge port 31. Specifically, the lifting seat 54 can be lifted by a telescopic rod or by a driver.

[0079] A driver can be installed on the lifting seat 54. The output end of the driver is connected to the toggle lever 53. When the lifting seat 54 extends into the discharge port 31 to clear blockages, the driver drives the toggle lever 53 to rotate, disturbing the material to clear blockages.

[0080] In this embodiment, by setting a toggle lever 53 and a lifting seat 54 in the unblocking component 5, the position of the toggle lever 53 is switched by the lifting movement of the lifting seat 54. When the material in the discharge port 31 is blocked, the unblocking operation is performed by disturbing the material, thus conveniently achieving the unblocking effect of the material.

[0081] In some embodiments, the tobacco feeder with the function of preventing material blockage at the feed inlet in this embodiment further includes: a controller and an alarm.

[0082] The detection component 4 is connected to the controller, and the controller is connected to the alarm.

[0083] The controller controls the working status of the alarm based on the material blockage information detected and fed back.

[0084] Understandably, when materials are being conveyed and become blocked in the discharge port 31, the controller will activate the alarm to alert the operator that there is a blockage in the discharge port 31 and allow them to respond promptly to prevent the entire conveyor line from becoming blocked.

[0085] The alarm can be a buzzer, which will sound an alarm when the material in the feed port 31 is blocked. The alarm can also be an audible and visual alarm, which will sound an alarm and light an alarm when the material in the feed port 31 is blocked.

[0086] This embodiment uses an alarm device to automatically alert operators when material at the discharge port 31 becomes blocked, eliminating the need for excessive manual intervention and improving conveying efficiency.

[0087] In some embodiments, such as Figure 1 and Figure 2 As shown, the elevator 2 in this embodiment includes a conveyor belt 22 and a drive unit 23.

[0088] The drive unit 23 is connected to the conveyor belt 22 for transmission, and the controller is connected to the drive unit 23.

[0089] The controller controls the start and stop of the drive unit 23 based on the material blockage information fed back by the detection component 4.

[0090] Understandably, when material gets blocked at the discharge port 31, the elevator 2 needs to be stopped in time to prevent material from accumulating at the discharge port 31.

[0091] Specifically, the driving component 23 can be a motor.

[0092] In this embodiment, by setting up a drive component 23, when material in the discharge port 31 becomes blocked, the controller can control the drive component 23 based on the blockage information fed back to the controller by the detection component 4, thereby controlling the conveyor belt 22 to stop running, so that material no longer continuously enters the discharge port 31, preventing further blockage and production interruption, so as to achieve precise control of the material conveying amount in the discharge port 31, thereby further improving the uniformity of material conveying.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
