Description

Technical Field

[0001] This utility model relates to the field of tobacco production equipment technology, and in particular to a sealing device for a feeding elevator and a feeding elevator. Background Technology

[0002] The feeding system before the tobacco drying machine consists of an elevator, a feeding hopper, a limiting tube, and an electronic lifting belt scale. In the tobacco drying process of the production line, after the tobacco leaves are shredded, the shredded tobacco is sent to the feeding hopper, and then fed to the drying machine at a relatively constant flow rate via the elevator to ensure the stability of the drying flow. When the elevator lifts the tobacco, the rake teeth installed on the lifting belt drive the tobacco upwards with the belt. During this process, the side plates remain stationary, and a gap needs to be left between the side plates and the conveyor belt for the conveyor belt to move. As a result, some of the tobacco rising during the process falls into the gap under the action of the rake teeth and its own weight, increasing the risk of damage to the machine's interior due to tobacco entering. Furthermore, the tobacco falling into the gap can be crushed by the side plates, further increasing the loss of raw tobacco materials during transportation.

[0003] In the early stages, guide plates were added to the gap between the side plates and the conveyor belt, and brushes were added between the guide plates and the conveyor belt to reduce the chance of tobacco entering the gap. However, after running for a period of time, it was found that in the transition section, due to its arc shape, the tobacco was more likely to get stuck when the conveyor belt was running, resulting in more breakage. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a sealing device for a feeding elevator and a feeding elevator. By adding a sealing structure between the transition section and the conveyor belt of the feeding elevator, the probability of tobacco getting stuck in the transition section can be effectively reduced, thereby reducing breakage.

[0005] This utility model solves the above-mentioned technical problems through the following technical means:

[0006] A sealing device for a feeding elevator includes a transition section and a sealing structure. The transition section is fan-shaped, and there is a gap between the bottom of the transition section and the conveyor belt of the feeding elevator. The sealing structure is disposed on the transition section and covers the gap, and is used to blow air from the gap to the conveyor belt to reduce the probability of tobacco getting stuck in the gap.

[0007] According to the above-mentioned technical means, by setting a sealing structure in the transition section, the gap between the bottom of the transition section and the conveyor belt can be covered. On the one hand, most of the tobacco can be blocked to prevent it from entering the gap. On the other hand, by blowing air into the gap, the probability of tobacco getting stuck in the gap can be further reduced.

[0008] Furthermore, the sealing structure includes a pressure strip, a sealing plate, and an air blowing structure. The pressure strip is disposed on the transition section, the sealing plate is fixedly disposed on the pressure strip, and the air blowing structure is disposed at the gap for blowing air into the gap between the sealing plate and the conveyor belt.

[0009] According to the above-mentioned technical means, by forming a gap between the pressure strip and the conveyor belt, the air blowing structure can blow air out from the gap during operation, which can blow out the tobacco that has entered the gap, thereby reducing the probability of tobacco getting stuck during long-term operation.

[0010] Furthermore, the air blowing structure includes an air supply pipe and an air blowing pipe. One end of the air supply pipe is fixedly connected to the air blowing pipe. The air blowing pipe is fixedly installed on the transition section. The air blowing pipe is provided with multiple air holes, and the multiple air holes are opposite to the sealing plate.

[0011] Based on the above technical means, by cooperating the air supply pipe and the air blowing pipe, air blowing can be performed when the wire feeding pipe is connected to the factory's air source. The structure is simple and highly practical.

[0012] Furthermore, the sealing structure also includes a reinforcing plate, which is inclined and its free end is connected to the side of the sealing plate near the transition section.

[0013] Based on the above technical means, by setting up a reinforcing plate, the support effect on the sealing plate can be enhanced, and the gap between the sealing plate and the conveyor belt can be prevented from increasing during long-term use due to the operation of the conveyor belt and the jamming and squeezing of tobacco.

[0014] Furthermore, the sealing plate includes a first bend, a second bend, and a third bend, which are fixedly connected. The first bend is detachably connected to the transition section, the second bend is detachably connected to the pressure strip, and the free end of the third bend is connected to the conveyor belt.

[0015] According to the above-mentioned technical means, bending the sealing plate into the corresponding shape is beneficial to its fit with the pressure strip and the conveyor belt.

[0016] Furthermore, the first bend, the second bend, and the third bend are integrally formed.

[0017] Based on the above-mentioned technical means, the integral molding facilitates the molding and use of the sealing plate.

[0018] Furthermore, locking blocks are fixedly connected to both sides of the pressure strip.

[0019] Based on the above technical means, by setting locking blocks on both sides of the pressure strip, the gap height between the pressure strip and the conveyor belt can be controlled by controlling the locking depth of the locking blocks during installation, which is simple and convenient.

[0020] This application also discloses a feeding elevator, including a horizontal conveying section, a conveyor belt, an elevator section, and the aforementioned sealing device for the feeding elevator. The sealing device for the feeding elevator is disposed between the horizontal conveying section and the elevator section, and the conveyor belt is disposed between the horizontal conveying section, the elevator section, and the sealing device for the feeding elevator.

[0021] According to the above-mentioned technical means, by using the above-mentioned sealing device in the feeding elevator, the probability of tobacco getting stuck in the transition section can be reduced, thereby reducing breakage.

[0022] Furthermore, pressure blocks are provided on both the horizontal conveying section and the lifting section, and sealing blocks are provided on the pressure blocks.

[0023] According to the above-mentioned technical means, by setting pressure blocks and sealing blocks on both the horizontal conveying section and the lifting section, it is possible to reduce the amount of tobacco falling into the gap between the conveyor belt and the side plate.

[0024] The present application, employing the above-described scheme, has the following beneficial effects:

[0025] 1. In this application, a sealing structure is provided at the transition section of the elevator, which can cover the gap between the bottom of the transition section and the conveyor belt. On the one hand, it can block most of the tobacco and prevent it from entering the gap. On the other hand, by blowing air into the gap, the probability of the tobacco getting stuck in the gap can be further reduced.

[0026] 2. The sealing structure in this application is configured as a pressure strip, a sealing plate, and an air blowing structure. By forming a gap between the pressure strip and the conveyor belt, the air blowing structure can blow air out from the gap during operation. In conjunction with the sealing plate, it can blow out the tobacco that has entered the gap, thereby reducing the probability of tobacco getting stuck during long-term operation.

[0027] 3. The feeding elevator with a sealed structure ensures smooth lifting of tobacco materials and reduces equipment maintenance costs. Attached Figure Description

[0037] like Figure 1-2As shown in the figure, this application discloses a sealing device for a feeding elevator, including a transition section 100 and a sealing structure 200. The transition section 100 is fan-shaped, and there is a gap between the bottom of the transition section 100 and the conveyor belt 500 of the feeding elevator. The sealing structure 200 is disposed on the transition section 100 and covers the gap, and is used to blow air from the gap towards the conveyor belt to reduce the probability of tobacco getting stuck in the gap.

[0038] In this embodiment, by providing a sealing structure 200 in the transition section 100, the gap between the bottom of the transition section 100 and the conveyor belt 500 can be covered. On the one hand, most of the tobacco can be blocked during the tobacco lifting process to prevent it from entering the gap. On the other hand, by blowing air outward into the gap, the probability of the tobacco getting stuck in the gap can be further reduced.

[0039] In this embodiment, the transition section 100 is fan-shaped as a whole, and both the upper and lower sides of the transition section 100 are arc-shaped, which facilitates connection with the rest of the feeding elevator.

[0040] In this embodiment, as Figure 1 As shown, the sealing structure 200 includes a pressure strip 210, a sealing plate 230, and an air-blowing structure 220. The pressure strip 210 is disposed on the transition section 100 to form a gap with the conveyor belt 500. The sealing plate 230 is fixedly disposed on the pressure strip 210, with its free end close to the upper surface of the conveyor belt 500, for sealing the gap. The air-blowing structure 220 is disposed at the gap for blowing air into the gap between the sealing plate 230 and the conveyor belt 500, which can blow out the tobacco that has entered the gap, thereby reducing the probability of tobacco getting stuck during long-term operation and thus reducing breakage.

[0041] In this embodiment, the pressure strip 210 has a trapezoidal cross-section and is arranged on the inner side of the transition plate along the running direction of the conveyor belt 500. A gap is formed between the bottom of the pressure strip 210 and the conveyor belt 500, forming an arc shape. The height of the gap is 8-14mm. The air blowing structure 220 is arranged at the transition section 100 and corresponds to the gap. The sealing plate 230 is fixedly installed on the outside of the pressure strip 210 by screws and covers the gap.

[0042] In this embodiment, in order to facilitate the control of the gap height, both sides of the pressure strip 210 are fixedly connected with locking strips, so that the pressure strip 210 can be installed by controlling the different locking depths of the locking strips, which is simple and practical.

[0043] In this embodiment, as Figure 2As shown, the air blowing structure 220 includes an air supply pipe 221 and an air blowing pipe 222. One end of the air supply pipe 221 is fixedly connected to the air blowing pipe 222, and the other end is connected to an external air source for conveying airflow. The air blowing pipe 222 is fixedly mounted on the transition section 100 by a snap fastener. The air blowing pipe 222 is provided with multiple air holes 223, which correspond to the gaps, so that when the airflow is blown out from the air holes 223, it can pass through the gaps and the part where the sealing plate 230 connects with the conveyor belt 500.

[0044] In this embodiment, in order to make the multiple air holes 223 fit the arc-shaped gap as closely as possible, the air blowing pipe 222 is arc-shaped, and the multiple air holes 223 are evenly distributed on the air blowing pipe 222 at equal angles.

[0045] In this embodiment, as Figure 2 As shown, the sealing plate 230 includes a first bent portion 231, a second bent portion 232, and a third bent portion 233. The first bent portion 231, the second bent portion 232, and the third bent portion 233 are fixedly connected to form a bendable whole. The first bent portion 231 is detachably connected to the transition section 100 by screws, the second bent portion 232 is detachably connected to the pressure strip 210 by screws, and the free end of the third bent portion 233 is connected to the conveyor belt 500, thereby stably installing the sealing plate 230 in the transition section 100 and covering the gap with the free end of the sealing plate 230.

[0046] In this embodiment, the sealing plate 230 is made of a flexible material and is integrally molded, making it easy to be bent into different shapes according to different usage conditions. The flexible material can be tin foil with a thickness of 1-5mm, or it can be abrasion-resistant rubber material, silicone material, etc.

[0047] In this embodiment, a reinforcing plate 212 is also fixedly connected to the bottom of the pressure strip 210. The reinforcing plate 212 is inclined so that the free end of the reinforcing plate 212 is connected to the inner side of the third bend, thereby enhancing the support for the third bend and preventing the gap between the sealing plate 230 and the conveyor belt 500 from increasing due to the operation of the conveyor belt 500 and the jamming and squeezing of the tobacco during long-term use.

[0048] In this embodiment, to enhance the support effect, the third bend is bent inward at the junction with the conveyor belt 500, and the end of the reinforcing plate 212 abuts against the inward bend. To avoid affecting the airflow effect, multiple perforations are provided on the reinforcing plate 212.

[0049] In this embodiment, during operation, by opening the air supply pipe 221, the airflow enters the blowing pipe 222 from the air source through the air supply pipe 221, and is blown out along the air hole 223, and blown along the gap towards the reinforcing plate 212 and the sealing plate 230. When tobacco leaves remain or get stuck at the third bend, the airflow can cause the tobacco leaves to detach and reduce the probability of them entering the gap between the sealing plate 230 and the conveyor belt 500.

[0050] like Figure 3 As shown in the illustration, this application also discloses a feeding elevator, including a horizontal conveying section 300, a conveyor belt 500, an elevator section 400, and a sealing device for the feeding elevator described in the above embodiment. The sealing device for the feeding elevator is disposed between the horizontal conveying section 300 and the elevator section 400, and the conveyor belt 500 is disposed between the horizontal conveying section 300, the elevator section 400, and the sealing device for the feeding elevator, for conveying and lifting tobacco shreds.

[0051] In this embodiment, multiple rake teeth 510 are fixedly installed at equal intervals on the conveyor belt 500 to better transport and lift the tobacco.

[0052] In this embodiment, to reduce the amount of tobacco falling into the gap between the conveyor belt 500 and the side plate, pressure blocks 310 are fixed on both the horizontal conveying section 300 and the lifting section 400. Sealing blocks 320 are fixed to the pressure blocks 310 by screws. To ensure better connection between the sealing block 320 and the sealing plate 230, and to seal the conveyor belt 500, the sealing block 320 is made of the same material as the sealing plate 230. Similarly, it also has three bends, overlapping with the third bend of the transition section 100. This reduces the amount of tobacco falling into the gap between the conveyor belt 500 and the side plate, and also allows airflow to blow along the gap between the pressure block 310 and the conveyor belt 500, further reducing the likelihood of tobacco entering the horizontal conveying section 300 and the lifting section 400.

[0053] In this embodiment, a slot is provided at the part where the pressure block 310 and the pressure strip 210 meet, so that the pressure strip 210 can be inserted into the slot on the pressure block 310.

[0054] In this embodiment, the gap between the conveyor belt 500 and the pressure block 310 will not affect the operation of the conveyor belt 500.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
