Description

Technical Field

[0001] This invention relates to the field of tobacco production technology, and in particular to a material recycling device. Background Technology

[0002] During the tobacco production process, some material leakage will occur at the bottom of the feeder. After a normal shift, 20-30 kg of tobacco material will accumulate in the ash collection box at the bottom of the feeder. Moreover, the material is unevenly piled up in the ash collection box, so some material will leak out of the ash collection box and fall onto the ground or supporting structure. Finer dust is easily dispersed into the air and affects the production environment.

[0003] Currently, the handling of leaked material involves manually sweeping it out of the ash collection box, storing the swept material in a temporary storage bin, and finally manually remixing it back into the feeder's hopper for production use. In this process, excessive accumulation of tobacco can lead to spillage and breakage, resulting in waste. Furthermore, manual sweeping can damage the tobacco, and the spilled tobacco can easily introduce impurities, affecting its quality. Remixing this impure material back into the feeder's hopper severely impacts the quality of the final product. Repeated sweeping also increases the workload, leading to fatigue and reduced efficiency, ultimately impacting production productivity. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a material recycling device, including a collection part and a remixing part. The collection part is installed at the leakage point of the feeder's conveyor belt, and the remixing part is connected to the collection part and installed directly above the feeder's hopper. The collection part collects the leakage material, and the remixing part collects the collected material a second time and remixes it back into the feeder's hopper, thus completing the automatic recycling of materials. The present invention utilizes mechanical automation to effectively solve the problem of decreased work efficiency that occurs with manual collection and remixing, improves production efficiency, and reduces labor costs. When using the collection device of the present invention to collect leakage material, the material will not come into contact with the ground and no debris will be mixed in, thereby effectively eliminating the problem of decreased tobacco quality and reducing material waste.

[0005] The technical solution to the problem of this invention is to provide a material recycling device, which is installed between the material drop point and the bin opening at the bottom of the feeding belt of a feeder, for collecting and remixing materials. The device of this application includes a collecting device, a conveying device, and a collection bin. The collecting device for collecting materials is located at the material drop point, and the collection bin is installed directly above the bin opening. The two ends of the conveying device are respectively connected to the collecting device and the collection bin, so that the material collected by the collecting device can be conveyed by the conveying device to the collection bin and fall from the bin opening into the feeder's hopper.

[0006] Furthermore, the collection bin includes a bin door, control components, and a bin body. The bin door is located at the lower end of the bin body, and a sealing ring is installed between the bin door and the bin body so that the collection bin can always remain sealed when the bin door is closed. The control components are installed on the outer wall of the bin body to control the opening and closing of the bin door, so that the material inside the bin can be mixed into the feeder's hopper.

[0007] Preferably, the hopper is divided into two parts: an upper column and a lower frustum. The smaller radius of the frustum is positioned with the hopper opening facing downwards, while the larger radius is connected to the column and has the same radius as the bottom surface of the column.

[0008] Preferably, the warehouse is equipped with a transparent observation window to view the material accumulation status within the warehouse.

[0009] Preferably, the control component is a cylinder, which can be further divided into a piston and a cylinder body. It is installed on the outer wall of the chamber body. The upper end of the piston is connected to the chamber door. When the piston retracts into the cylinder body, the chamber door rotates downward about the point of connection with the piston, and the chamber door opens. The cylinder is controlled by an external circuit to drive the chamber door to rotate and open at a set time.

[0010] Furthermore, when the bin door is opened, the opening at the lower end of the collection bin is the bin opening, and the size of the bin opening is smaller than the size of the feeder's bin opening.

[0011] Furthermore, the transmission device includes a connecting pipe and a drive unit. The two ends of the connecting pipe are respectively connected to the material storage area of ​​the silo and the collection device, and the drive unit is connected to the silo.

[0012] Furthermore, the drive unit includes a negative pressure pipe and a shut-off valve. One end of the negative pressure pipe is connected to the interior of the collection bin, and the other end is connected to the negative pressure system of the workshop where the feeder is located. A shut-off valve is installed on the negative pressure pipe. When the bin door is closed, the drive unit provides negative pressure airflow to draw the material in the material storage area to the collection bin through the connecting pipe.

[0013] Furthermore, the connecting pipe and the negative pressure pipe are located at opposite corners on the top of the chamber.

[0014] Furthermore, a filter device is installed at the connection between the negative pressure pipe and the chamber body to filter the airflow entering the negative pressure pipe.

[0015] Optionally, the filtration device can be a filter screen, air filter element, etc., installed inside the collection chamber and connected to the negative pressure pipe, which can prevent debris and materials from entering the negative pressure pipe.

[0016] Furthermore, the collection device includes a conveying device and a collection bin. The conveying device is located at the material drop point at the bottom of the feeder's feeding belt, and the collection bin is located at the material output end of the conveying device to receive the material collected by the conveying device; the collection bin is the material storage area of ​​the collection device.

[0017] Furthermore, the collection bin is located below the material output end of the conveying device, and the opening size of the collection bin is larger than the width of the conveying device; the material receiving range of the conveying device is larger than the material dropping range of the dropping point.

[0018] Optionally, the collection bin can be a cuboid, cylinder, or any container with an open top that can hold materials.

[0019] Furthermore, the conveying device includes a first conveyor belt and a second conveyor belt. The first conveyor belt is horizontally positioned below the material drop point at the bottom of the feeder's feeding belt. The second conveyor belt is positioned below the tail end of the first conveyor belt and is perpendicular to the direction of the first conveyor belt, so that the material received by the first conveyor belt can be transferred to the second conveyor belt. The tail end of the second conveyor belt is the material output end of the conveying device. The length of the second conveyor belt is greater than the width of the first conveyor belt.

[0020] Preferably, the material output range of the first conveyor belt is within the material receiving range of the second conveyor belt.

[0021] Preferably, baffles are provided on both sides of the first conveyor belt to prevent materials from falling after accumulating.

[0022] Preferably, the tail end of the second conveyor belt is provided with a suspended guide plate. The guide plate is installed on the side support frame of the first conveyor belt near the tail end of the second conveyor belt, and forms a triangle with the two right-angled sides of the second conveyor belt that are farther from the connection port, in order to guide the material on the second conveyor belt to fall into the collection bin near the connection pipe.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention is a material recycling device, which is installed between the material drop point of the feeder's conveyor belt and the bin opening. It utilizes the workshop's negative pressure system to achieve automatic material recycling, thereby reducing labor costs.

[0025] 2. Traditional methods of collecting leaked tobacco tend to accumulate too much tobacco, causing it to spill and break, resulting in waste. The device in this application automatically remixes the tobacco when it accumulates to a certain amount, thus avoiding waste.

[0026] 3. Traditional manual collection methods are prone to introducing debris during the process of sweeping tobacco and placing it into a temporary storage box. The device of this application uses a conveyor belt to transport the tobacco directly to the collection bin, thus avoiding the introduction of debris.

[0027] 4. Each batch requires manual cleaning, collection, and remixing. Too much frequency can lead to insufficient physical strength of workers and reduced work efficiency. The device of this application can realize automatic "collection-remixing" integrated operation, reduce the labor force of workers, and improve work efficiency and production efficiency.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To address the aforementioned issues, this invention proposes a material recycling device, which is installed on the blending and flavoring feeder in a tobacco production line. This device performs an integrated "collection-remixing" operation on the material falling from the bottom of the feeder, aiming to solve the problems of material waste, low work efficiency, and foreign matter mixing into the material that occur when manually collecting and remixing the material in the existing stage.

[0035] Please refer to the specific embodiments of this application. Figure 1 and Figure 2 :

[0036] A material recycling device includes a collection device 1, a conveying device 2, and a collection bin 3. The collection device 1, used to collect materials, is located at the material drop point, and the collection bin 3 is installed directly above the bin opening. The two ends of the conveying device 2 are respectively connected to the collection device 1 and the collection bin 3, so that the material collected by the collection device 1 can be conveyed by the conveying device 2 to the collection bin 3 and fall from the bin opening into the feeder's hopper, effectively preventing material drop and dust dispersion.

[0037] The material recycling device of this application includes a collection part and a remixing part. The collection part is a collection device 1, which includes a conveying device 11 and a collection bin 12. The conveying device 11 is located at the material drop point of the feeder belt, and the receiving range of the conveying device 11 is larger than the material drop range. The collection bin 12 is located below the material output end at the tail end of the conveying device 11.

[0038] The back-mixing section includes a transmission device 2, a collection bin 3, and a filter device 4. The collection bin 3 includes a bin door 31, a control component 32, and a bin body 33. A sealing ring is provided between the bin door 31 and the bin body 33. The control component 32 is located on the outer wall of the bin body 33 to control the opening and closing of the bin door 31. The transmission device 2 includes a connecting pipe 21 and a drive unit 22. The drive unit 22 includes a negative pressure pipe 221 and a shut-off valve 222. The two ends of the connecting pipe 21 are respectively connected to the collection bin 12 and the collection bin 3. The two ends of the negative pressure pipe 221 are respectively connected to the collection bin 3 and the negative pressure system of the workshop where the feeder is located. The shut-off valve 222 is located on the outer wall of the negative pressure pipe 221. The connecting pipe 21 and the negative pressure pipe 221 are located at opposite corners on the top of the bin body 33. The filter device 4 is located at the connection between the negative pressure pipe 221 and the inside of the bin body 33.

[0039] After the conveying device 11 collects the falling material, it is transported to the collection bin 12. The shut-off valve 222 is opened, which connects the negative pressure pipe 221, the collection bin 3, the connecting pipe 21 and the collection bin 12. The negative pressure pipe 221 draws the material in the collection bin 12 to the collection bin 3. The filter device 4 is used to filter the airflow entering the negative pressure pipe 221. When the set suction time is reached, the shut-off valve 222 is closed, which disconnects the negative pressure pipe 221 from the collection bin 3, the connecting pipe 21 and the collection bin 12. Finally, the control device 32 opens the bin door 31, which allows the material to fall from the collection bin 3 into the feeder's bin, completing the automatic recovery of the material.

[0040] In one specific embodiment, the conveying device 11 can be a conveyor belt, and the collection bin 12 is located below the end of the conveyor belt. While the negative pressure pipe 221 draws in the material in the collection bin 12, the conveyor belt transports the falling material to the collection bin 12. However, since the collection bin 12 is too close to the falling point and the upper end of the collection bin 12 is open, the negative pressure pipe 221 will suck the material accumulated on the conveyor belt that has not yet been transported into the collection bin 12 to the ground, resulting in material waste. If the material on the ground is not cleaned up in time, it will breed insects and affect the process quality. Moreover, this type of setup requires a large amount of space.

[0041] To address the aforementioned problems in practical applications, please refer to the specific embodiments of this application. Figure 1 and Figure 2 :

[0042] The conveying device 11 includes a first conveyor belt 111 and a second conveyor belt 112. The first conveyor belt 111 is horizontally positioned below the material drop point at the bottom of the feeder's feeding belt. The second conveyor belt 112 is positioned below the tail end of the first conveyor belt 111 and is perpendicular to the first conveyor belt 111, extending the conveying distance of the conveying device 11. The collection bin 12 is positioned below the tail end of the second conveyor belt 112. This configuration is stacked, thus occupying less space.

[0043] As a preferred embodiment, please refer to Figure 3 :

[0044] The first conveyor belt 111 is provided with baffles 113 on both sides to prevent the material from falling outside the first conveyor belt 111 when it accumulates.

[0045] The tail end of the second conveyor belt 112 is provided with a suspended guide plate 114. The guide plate 114 is installed on the side support frame of the first conveyor belt 111 near the tail end of the second conveyor belt 112, forming a triangle with the two right-angled sides of the second conveyor belt 112 that are farther from the connection port. Because the suction force of the negative pressure pipe 221 is limited, materials that are far from the connection port may not be sucked up normally. Therefore, the guide plate 114 is added to guide the material to fall to the position near the collection bin 12 and the connection port of the connecting pipe 21, so that the material in the collection bin 12 can be sucked up normally to the collection bin 3, and at the same time, it can also prevent the accumulated material from falling outside the second conveyor belt 112.

[0046] In a preferred embodiment, the length of the second conveyor belt 112 is greater than the width of the first conveyor belt 111, so that the material transported by the first conveyor belt 111 can fall stably onto the second conveyor belt 112.

[0047] It is understandable that a baffle can be provided on the opposite side of the second conveyor belt 112 relative to the first conveyor belt 111 to prevent materials falling from the first conveyor belt 111 onto the second conveyor belt 112 from falling outside the second conveyor belt 112 due to inertia.

[0048] Similarly, baffles can be set on both sides of the first conveyor belt 111 to prevent materials from falling off the first conveyor belt 111 due to inertia.

[0049] In one specific embodiment, if the second conveyor belt 112 is horizontal, the collection bin 12 is located below the end of the second conveyor belt. However, due to height limitations, the height of the collection bin 12 is low and the capacity is small. When the suction speed is slow, material will accumulate in the collection bin 12. If the accumulation is too high, it will spill, causing material waste and contaminating the ground.

[0050] Based on the problems encountered in practical applications described above, please refer to the specific embodiments of this application. Figure 2 :

[0051] The tail end of the second conveyor belt 112 is upward-curving, which allows for more space below the tail end of the second conveyor belt 112, increases the height of the collection bin 12, increases the capacity, and prevents the accumulated material from falling off when the suction speed is slow.

[0052] In a preferred embodiment, the size of the opening of the collection bin 12 is larger than the length of the second conveyor belt 112, so that the material output from the conveying device 11 can be collected by the collection bin 12.

[0053] In one specific embodiment, when the door 31 of the collection bin 3 is opened, the opening at the lower end of the collection bin 3 is the bin opening. If the size of the bin opening of the collection bin 3 is not smaller than the size of the bin opening of the feeder bin, when the bin door 31 is opened to return materials, some materials will spill out of the feeder bin.

[0054] Based on the problems encountered in practical applications, in a specific embodiment of this application, the opening size of the collection bin 3 is smaller than the opening size of the feeder bin.

[0055] In one feasible embodiment, the collection bin 3 is a column, and the size of the opening of the collection bin 3 is smaller than the size of the opening of the feeder bin. However, due to the small bottom area of ​​the collection bin 3, the stability of the overall device during installation, and the limited height in the workshop, the storage space of the collection bin 3 is small. It is necessary to frequently open and close the shut-off valve 222 and the control component 32 to empty the material in the collection bin 3 so that the collection bin 3 can collect the remaining material.

[0056] In a preferred embodiment, the collection chamber 3 is divided into a door 31, a control component 32, and a body 33. The body 33 is divided into two parts: an upper column and a lower frustum. The smaller radius of the frustum is the opening, which faces downwards. The larger radius is connected to the column and has the same radius as the bottom of the column, making the collection chamber 3 have a shape that is wider at the top and narrower at the bottom. This increases the capacity of the collection chamber 3 and reduces the need for frequent switching of the shut-off valve 222 and the control component 32.

[0057] As a preferred embodiment, a sealing ring is provided between the door 31 and the chamber body 33. When the negative pressure pipe 221 draws and absorbs the material in the collection chamber 12, the door 31 is closed. The sealing ring is used to prevent airflow from leaking out from the door 31 and affecting the suction effect.

[0058] In one specific embodiment, if the entire collection chamber 3 is made of opaque material, it will be impossible to observe the amount of stockpiled inside the collection chamber 3, and it will be impossible to preset the suction time and the time for the chamber door 31 to remain open.

[0059] Based on the problems encountered in practical applications, in a specific embodiment of this application, the upper part of the collection chamber 3 is provided with a transparent observation window to observe the amount of stockpiled inside the collection chamber 3, so as to pre-set the suction time and the time for the chamber door 31 to remain open / closed.

[0060] As a feasible embodiment, the negative pressure pipe 221 and the connecting pipe 21 are located on the same side of the top of the chamber 33 and are close to each other. When the negative pressure pipe 221 is sucking, due to the close distance with the connecting pipe 21, the suction force will gradually decrease after the material is gradually sucked into the collection chamber 3.

[0061] In a preferred embodiment, the negative pressure pipe 221 and the connecting pipe 21 are located at opposite corners on the top of the chamber 33, increasing the distance between the two connection ports. This makes it less likely for materials to accumulate at the connection port of the negative pressure pipe 221, thus not affecting the suction force.

[0062] In one specific embodiment, if the connection between the negative pressure pipe 221 and the chamber 33 is not equipped with a filter device 4, the material will be directly drawn into the negative pressure pipe 221, causing the negative pressure pipe 221 to become blocked.

[0063] Based on the above problems, in a specific embodiment of this application, a filter device 4 is provided at the connection between the negative pressure pipe 221 and the interior of the chamber 33 to prevent debris from entering the negative pressure pipe 221.

[0064] It is understandable that the filter device 4 can be a filter screen, air filter element, etc., which can filter the airflow and prevent impurities and materials from entering the negative pressure pipe 221.

[0065] The device described in this application can work in conjunction with a feeder during production. The start-up time can be preset; after the feeder has been operating for half an hour, the device automatically starts, the shut-off valve 222 opens, and the negative pressure pipe 221 remains in a suction state. At this time, the door 31 of the collection chamber 3 is closed. The first conveyor belt 111 transports the accumulated material to the second conveyor belt 112, which then transports the received material to the collection chamber 12. The negative pressure pipe 221, through the connecting pipe 21, draws the material from the collection chamber 12 into the collection chamber 3. The filter device 4 can prevent… Material enters the negative pressure pipe 221; when the preset suction time is reached, the first conveyor belt 111 and the second conveyor belt 112 stop working, and at the same time, the shut-off valve 222 closes the negative pressure pipe 221 to stop suction. The control unit 32 opens the door 31 of the collection bin 3, allowing the material in the bin to fall into the feeder; when the preset discharge time is reached, the control unit 32 controls the door 31 of the collection bin 3 to close, and at the same time, the first conveyor belt 111 and the second conveyor belt 112 start working, the shut-off valve 222 opens, and the negative pressure pipe 221 starts to suck up the material, thus repeating the cycle. When the feeder stops working, the device of this application starts for five minutes to empty the material in the device of this application.

[0066] It is understood that the device of this application can be started manually or operated automatically, and the preset time can be adjusted according to different situations. By observing the collection situation in the collection chamber 3 after the first manual start, the suction time and emptying time can be determined, so that the device of this application can operate automatically in a cycle.

[0067] The above-described contents can be implemented individually or in various combinations, and these variations are all within the protection scope of this invention.

[0068] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

It should not be construed that the specific embodiments of the present invention are limited to these descriptions.
