Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a leak-proof elevator. Background Art

[0002] In the process of making chili sauce, the lifting and transportation of chili peppers is a crucial step. However, when transporting chili peppers, due to the fact that fresh chili peppers themselves contain a certain amount of moisture, they have a certain elasticity. This elasticity may cause some problems during the lifting process. Specifically, when chili peppers are transported in the lifting trough of the elevator, due to jitter or other external forces, the chili peppers may pop out of the lifting trough. This phenomenon will cause the chili peppers to break away from the elevator, thus affecting the transportation efficiency of the entire chili sauce. The splashing of chili peppers not only makes it inconvenient for production and cleaning in the factory building, but also poses a safety hazard. In addition, after the chili peppers rot, they will affect the processing environment of the factory, produce bad odors, and may even cause equipment failures. Therefore, during the lifting and transportation of chili peppers, effective measures must be taken to prevent the chili peppers from popping out to ensure the production efficiency of chili sauce and the sanitary environment of the factory.

[0003] In the patent "elevator" (publication number: CN203512573U, hereinafter referred to as the prior art 1), an elevator for the food industry is disclosed. In the prior art 1, the vertical lifting of materials is achieved through a material conveying device, including a bottom conveying section, a vertical lifting section, and a top conveying section. The uniform feeding of materials is realized through the rotational movement of the cloth roller. Through the bottom conveying end of the hopper conveying device, the materials are fed evenly, avoiding uneven feeding and material movement caused by manual operation. Through the vertical lifting section, the materials are directly lifted from the bottom to the top, with high lifting efficiency and small occupied space. In addition, by setting the bottom conveying section, the vertical lifting section, and the top conveying section as an integrated structure, the continuous operation of material feeding, material movement, and lifting is realized, and with different working platforms, the working efficiency is maximized.

[0004] Although in the prior art 1, the continuous operation of materials during feeding, material movement, and lifting is successfully achieved through setting. However, in the food industry, especially when dealing with agricultural products, these materials often have certain special properties. For example, the shape, size, texture, etc. of agricultural products may vary depending on the variety, which makes these edible agricultural products more likely to slip out from the inside of the elevator during the lifting process. This slipping may not only lead to accidents during transportation, but also cause waste of materials, thus affecting the overall production efficiency and processing environment. Therefore, although the prior art has achieved certain results in improving work efficiency, there are still certain limitations and room for improvement when lifting and transporting agricultural products with special properties.

[0028] Embodiment 1

[0029] Please refer to Figure 1 , the embodiments of the present utility model provide a leak - proof elevator, and the leak - proof elevator of the present utility model is used to solve the problem that when transporting the raw material pepper of chili sauce by the elevator, it is easy to fall out of the elevator.

[0030] Please refer toFigure 1 , in this embodiment, a leakage-proof elevator is provided. The device mainly includes a sturdy frame 100 and a lifting belt 110 mounted on the frame 100. The frame 100 is set to be inclined, so as to effectively realize the lifting or horizontal transportation of the material pepper. During the transportation process, the pepper is evenly placed on the lifting belt 110, and then through the inclination angle of the frame 100, the material is smoothly lifted from a lower place to a higher place. Such a setting not only improves the transportation efficiency of the material but also enhances the safety.

[0031] The lifting belt 110 is sleeved on the rollers provided on the frame 100 to provide stable support and drive during the lifting process. These rollers are firmly fixed on the frame 100 and can rotate freely. When these rollers rotate during operation, the belt will move accordingly following the rotation of the rollers, thereby realizing the smooth lifting and conveying of the material. Such a setting ensures the efficient operation and reliability of the entire lifting system, and also facilitates the maintenance and replacement of the belt.

[0032] Please refer to Figure 1 , in the structural setting of the lifting belt 110, particularly, a series of partition plates 111 are arranged at uniform intervals along its length direction. First limit plates 112 and second limit plates 113 are respectively arranged on both sides of these partition plates 111. Specifically, the first limit plates 112 and the second limit plates 113 are installed on the two side edges of the lifting belt 110 and are closely joined to both sides of the partition plates 111. Through this setting, every two adjacent partition plates 111 and the first limit plates 112 and the second limit plates 113 on both sides of them jointly enclose a material cavity 114. During actual use, the pepper can be effectively stored inside these material cavities 114. As the lifting belt 110 moves, the material rises and is conveyed along the movement direction of the belt. The squeezing and friction between the material cavity 114 and the pepper can also play an effect of restricting the position of the pepper.

[0033] Furthermore, these partition plates 111, the first limiting plate 112, and the second limiting plate 113 are not installed independently, but are integrally structured with the lifting belt 110 itself. This integrated design not only simplifies the manufacturing process but also improves the overall stability and reliability. In addition, to adapt to the possible bending of the belt during transportation, the first limiting plate 112 and the second limiting plate 113 are designed as flexible plate structures. This flexible plate structure enables the first limiting plate 112 and the second limiting plate 113 to bend correspondingly when the belt bends, thus avoiding damage caused by folding. By adopting this flexible plate setting, the service life of the first limiting plate 112 and the second limiting plate 113 is significantly extended, and at the same time, the efficient and stable operation of the entire lifting system is ensured. Further, the flexible plate is a flexible plate made of materials such as rubber plates and silicone plates. Although different materials have their own unique properties, they also have some common properties, including wear resistance, being able to withstand friction and wear in daily use; elasticity or flexibility, enabling them to return to their original state when subjected to pressure or deformation.

[0034] Please refer to Figure 3 , the partition plate 111, the first limiting plate 112, and the second limiting plate 113 together form a specific material cavity 114 structure, which effectively prevents the peppers from falling off the belt during lifting. Through this setting, the material can remain stable during lifting, thus ensuring the smoothness of the entire conveying process and the integrity of the material.

[0035] Please refer to Figure 1 , furthermore, the two ends of the frame 100 are respectively configured with a feeding end 120 and a discharging end 130, and the positions of these two ports are covered by a housing 200. The setting of this housing 200 has two functions. First, it can ensure that the peppers do not fall off the lifting belt 110 during transportation, thus avoiding waste of peppers. Second, even if the peppers really fall off in some extreme cases, due to the protection of the housing 200, these peppers will only fall into other material cavities 114 of the lifting belt 110, thus avoiding possible accidents and waste of materials.

[0036] Specifically, the feeding end 120 is located at the top position of the lifting belt 110, and a feeding port 210 is specially provided on the housing 200 for this purpose. The peppers enter the lifting belt 110 through this feeding port 210, thus starting their conveying process. The design of the feeding port 210 makes the feeding of peppers more convenient and accurate, and at the same time ensures that the material does not accidentally scatter before entering the lifting belt 110. Please refer to Figure 2, and the discharge end 130 is located at the bottom position of the other end of the lifting belt 110. An outlet 220 is also provided on the housing 200. After the material is conveyed by the lifting belt 110, it is guided to the designated position through this outlet 220 to complete its conveying task. The setting of the outlet 220 makes the unloading process of the peppers smoother and also avoids unnecessary scattering of the peppers during the unloading process.

[0037] Please refer to Figure 1 , the design of the entire housing 200 is not only for aesthetics, but more importantly, to protect the feeding part of the lifting belt 110. The housing 200 completely covers the feeding part of the lifting belt 110, ensuring that the peppers will not fall off the belt during the lifting process. Since there is no material in the discharging part during the conveying process, the setting of the housing 200 in this part is unnecessary. Through this targeted protection measure, both the safety of pepper conveying is improved and the efficiency and smoothness of the entire conveying process are ensured.

[0038] In this embodiment, the roller includes three main parts: the bent roller, the first end roller 141, and the second end roller 142. The first end roller 141 and the second end roller 142 are respectively arranged at both ends of the frame 100 to ensure the stability of the entire system and uniform force transmission, thus forming a complete transmission chain.

[0039] Please refer to Figure 1 , at the left end of the frame 100, that is, the position where the first end roller 141 is located, a set of power transmission devices is provided. This set of devices includes a motor 151 and a reducer 152, which are closely matched through transmission connection. The motor 151 serves as the power source and is responsible for providing the initial power output. The reducer 152 plays the role of reducing the speed of the motor 151 and increasing the output torque, thus ensuring that the roller can operate at an appropriate speed and torque. There is also a transmission connection between the reducer 152 and the first end roller 141 to ensure that the power can be smoothly transmitted from the reducer 152 to the roller.

[0040] In this embodiment, the first end roller 141 is set as the driving wheel, which means it is directly driven by the motor 151. And the other rollers, including the bent roller and the second end roller 142, serve as driven wheels, and they rotate through contact and friction with the lifting belt 110. This setting enables the first end roller 141 to effectively drive the entire roller system, and then drive the lifting belt 110 to move. In this way, the lifting belt 110 can operate smoothly and efficiently under the auxiliary drive of the rollers, so as to achieve the smooth conveying and processing of materials.

[0041] Please refer to Figure 1, in this embodiment, the roller at the bending part includes two main parts, namely the first support roller 143 and the second support roller 144. These two rollers are respectively arranged at the bending part of the lifting belt 110, and their main function is to provide necessary support for the lifting belt 110 and assist in its effective transmission. In order to further enhance the support and transmission effect of the lifting belt 110.

[0042] Please refer to Figure 1 , the roller at the bending part also includes an additional third support roller 145. Specifically, the bending part of the lifting belt 110 is designed to have a concave part 115 and a convex part 116. The first support roller 143 is precisely installed on the convex part 116 to provide solid support for the lifting belt 110. At the same time, the second support roller 144 is placed inside the concave part 115 to ensure that the lifting belt 110 can obtain uniform and stable support when passing through the bending part. In addition, the third support roller 145 is arranged on the top of the concave part 115, and its purpose is to further enhance the stability of the lifting belt 110 at the bending part. To ensure that the third support roller 145 can effectively play its role, it is fixed by the frame 100 and can rotate freely based on the frame 100. In this way, the third support roller 145 can not only provide necessary support, but also make appropriate adjustments as needed during the operation of the lifting belt 110. At the same time, the first support roller 143, the second support roller 144 and the third support roller 145 are all arranged in contact with the lifting belt 110 to ensure that they can directly contact the lifting belt 110, so as to achieve a more efficient transmission and support effect.

[0043] Furthermore, please refer to Figure 1 , the first support roller 143, the second support roller 144 and the third support roller 145 not only play the role of support and transmission, but also have the function of a tensioning wheel. By contacting and squeezing the lifting belt 110, these rollers can effectively change the tension degree of the lifting belt 110, so as to ensure that the lifting belt 110 always maintains an appropriate tension during operation. This design not only improves the operation efficiency of the lifting belt 110, but also extends its service life, ensuring the stability and reliability of the entire lifting system.

[0044] Please refer to Figure 1 , in the internal structure of the frame 100, a set of auxiliary transmission support frames 160 are also specially set and installed. This set of auxiliary transmission support frames 160 are firmly fixed at the appropriate position of the frame 100 and are arranged in contact with the lifting belt 110. Such a design aims to provide additional support and transmission functions to ensure the stable operation of the lifting belt 110 and extend its service life.

[0045] Specifically, the auxiliary drive support frame 160 is composed of two side plates 161, which are fixed at corresponding positions on the frame 100. Between the two side plates 161, a series of drive rollers 162 are provided, and these drive rollers 162 are evenly distributed to ensure good contact with the lifting belt 110. To further enhance the support and drive effects, at least three drive rollers 162 are provided on each of the auxiliary drive support frames 160. These drive rollers 162 can not only share the load of the lifting belt 110, but also adjust and balance the tension of the belt to a certain extent, thereby improving the stability and reliability of the entire lifting system. Through this design, the failures caused by belt wear or overload can be effectively reduced, ensuring the efficient operation of the equipment.

[0046] Please refer to Figure 1 , during use, the chili peppers first enter the material cavity 114 of the lifting belt 110 through the feed port 210. Subsequently, the motor 151 is started, and the operation of the motor 151 will drive the first end roller 141 of the lifting belt 110 machine to start rotating. As the first end roller 141 rotates, the other rollers and the lifting belt 110 will also move accordingly. During the movement of the lifting belt 110, it will drive the material cavity 114 to gradually move upward, thereby transporting the material to the position of the discharge port 220. When the material reaches the discharge port 220, due to the action of gravity, the material will naturally fall from the discharge port 220, thus completing the entire material transportation process. This process is not only efficient, but also can ensure the stability and safety of the material during transportation.

[0047] Embodiment 2

[0048] Please refer to Figure 4 , an embodiment of the present utility model provides a leak-proof elevator. In this Embodiment 1, by forming a specific material cavity 114 structure between the partition plate 111 and the first limiting plate 112 and the second limiting plate 113, the chili peppers can be effectively prevented from falling off the lifting belt 110 during the lifting process. This design significantly improves the stability of the material during transportation, reducing material waste and environmental pollution.

[0049] Furthermore, in this embodiment, considering that when the inclination angle of the conveyor is relatively large, even if a material cavity 114 is formed between the partition plate 111, the first limiting plate 112, and the second limiting plate 113, the material may still fall off from the material cavity 114. To further improve the anti-leakage effect, in this embodiment, the partition plate 111 is particularly arranged in an inclined manner at a certain angle with the lifting belt 110. This inclined arrangement increases the extrusion force between the chili peppers and the material cavity 114 during the lifting process, confines the chili peppers inside the material cavity 114, and makes it more difficult for the chili peppers to escape from the lifting belt 110, thereby greatly enhancing the anti-leakage performance of the elevator. Through this arrangement, the stability of the chili peppers during transportation is further improved, ensuring that the material can be transported to the designated position more safely and efficiently.

[0050] Embodiment 3

[0051] Please refer to Figure 5 , the embodiment of the present utility model provides a leak-proof elevator. In Embodiment 2, when the partition plate 111 is inclined with respect to the lifting belt 110, the volume of the material cavity 114 will decrease, and the amount of material transported by each material cavity 114 will decrease.

[0052] Therefore, in this embodiment, the flat partition plate 111 arranged in an inclined manner is set as a "V"-shaped or "U"-shaped partition plate 111, so that the storage space in the material cavity 114 is larger than the volume of the material cavity 114 in Embodiment 2, enabling the material cavity 114 to transport more materials, and the materials will not escape from the lifting belt 110. This arrangement not only improves the transportation efficiency of the elevator but also effectively prevents the chili peppers from leaking during transportation, thus ensuring the smooth progress of the production process and the full utilization of the materials. Through the optimization of this structure, the performance and reliability of the overall equipment are improved, and at the same time, a safer and more convenient working environment is provided for the operators.

[0053] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
