DETAILED DESCRIPTION

[0027] In order to enable personnel in the technical field to better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.

[0028] According to the lifting system conveying bin structure of the embodiment of the present application, please refer to Figures 1 to 5 , comprising: a lifting support 1, the lifting support 1 is provided with a conveying belt 11; a conveying bin 2, the conveying bin 2 is fixed on the conveying belt 11, the conveying bin 2 moves along with the circulating rotation of the conveying belt 11, the conveying bin 2 is provided with a bin cover 21, the bin cover 21 is rotatably arranged relative to the conveying bin 2; a cover opening assembly 3, the cover opening assembly 3 comprises a guide component 31 and a moving component 32, the guide component 31 is arranged on the lifting support 1, the guide component 31 is movably arranged relative to the lifting support 1, the moving component 32 is arranged on the bin cover 21, when the guide component 31 moves to a specified position, the moving component 32 is guided to move on the guide component 31, and the bin cover 21 is driven to rotate relative to the conveying bin 2, so as to open the bin cover 21, so that the goods in the conveying bin 2 slide down. The conveying bin 2 is fixed on the mounting plate 27, the mounting plate 27 is fixed on the fixed plate 12, and the fixed plate 12 is fixed on the conveying belt 11, so that the conveying bin 2 is fixed on the conveying belt 11, and the conveying bin 2 moves along with the rotation of the conveying belt 11. The cover opening assembly 3 realizes the function of automatically opening the bin cover 21 of the conveying bin 2. When the conveying bin 2 is about to reach the specified position for unloading, the driving component 5 drives the guide component 31 to move towards the side close to the conveying bin 2, at this time the guide component 31 automatically guides the moving component 32 to move, and then drives the bin cover 21 to rotate and open, without manual intervention, simplifying the operation process of taking goods, and greatly improving the logistics conveying efficiency. The conveying bin structure of the lifting system of the embodiment solves the technical problems of the related art, such as the limitation of the conveying bin structure, the cumbersome operation of taking goods, and the influence on the conveying efficiency.

[0029] Specifically, the driving component 5 can be a cylinder that drives the moving component 32 to move by the extension and retraction of the piston rod, or can be a motor that drives the moving component 32 to reciprocate by the forward and reverse rotation of the motor.

[0030] With reference to Figure 1 and Figure 4 , the transmission bin structure of the lifting system of the embodiment, the transmission bin 2 includes a shell 22 and an inlet 23, the articles to be conveyed enter the shell 22 from the inlet 23, and the height of the inlet 23 from the horizontal plane is higher than the height of the bin cover 21 from the horizontal plane when the transmission bin 2 is transmitted upward, so that the shell 22 is inclined. When the transmission bin 2 is transmitted upward, the transmission bin 2 is in a state of carrying articles, and the height of the inlet 23 is higher than the height of the bin cover 21, which makes the shell 22 form an inclination relative to the horizontal plane. When the bin cover 21 is opened, the articles in the shell 22 can more naturally and smoothly slide along the inclined surface to the receiving area without additional thrust or auxiliary equipment, improving the efficiency and accuracy of article sliding.

[0031] With reference to Figure 1 , Figure 2 and Figure 3 , the transmission bin structure of the lifting system of the embodiment, the guide component 31 is a trapezoidal guide plate 311, the long side of the trapezoidal guide plate 311 is fixed on the lifting support 1, and the moving component 32 is a cover opening roller set 321; when the trapezoidal guide plate 311 moves to the specified position, the cover opening roller set 321 is clamped on the trapezoidal guide plate 311 and rolls along the edge of the trapezoidal guide plate 311, thereby driving the bin cover 21 to rotate. The structure of the trapezoidal guide plate 311 enables the cover opening roller set 321 to move along a specific trajectory during rolling, thereby achieving precise control of the rotation of the bin cover 21 and helping to ensure that the bin cover 21 is accurately opened at the specified position.

[0032] With reference to Figure 1 , Figure 2 and Figure 3The transmission bin structure of the lifting system of the embodiment is further provided with an elastic member 24, one end of the elastic member 24 is connected with the bin cover 21, and the other end of the elastic member 24 is connected with the shell 22; when the cover opening roller set 321 rolls along the trapezoidal guide plate 311, the bin cover 21 rotates so that the elastic member 24 is in a stretched state; when the cover opening roller set 321 is separated from the trapezoidal guide plate 311, the elastic member 24 resets and pulls the bin cover 21 to rotate, so that the bin cover 21 is covered on the shell 22. When the cover opening roller set 321 rolls along the trapezoidal guide plate 311, the bin cover 21 rotates, causing the elastic member 24 to be stretched. Once the cover opening roller set 321 is separated from the trapezoidal guide plate 311, the elastic member 24 will automatically reset due to its own elastic restoring force, pull the bin cover 21 to rotate and cover the shell 22. This design not only realizes the automatic resetting function of the bin cover 21, but also ensures that the bin cover 21 can be tightly covered on the shell 22 when not subjected to external force, preventing the articles from falling during the transmission process and improving the stability of the transmission of the articles.

[0033] Referring to Figures 1 to 4 The transmission bin structure of the lifting system of the embodiment is further provided with an elastic member 24, one end of the elastic member 24 is connected with the bin cover 21, and the other end of the elastic member 24 is connected with the shell 22; when the cover opening roller set 321 rolls along the trapezoidal guide plate 311, the bin cover 21 rotates so that the elastic member 24 is in a stretched state; when the cover opening roller set 321 is separated from the trapezoidal guide plate 311, the elastic member 24 resets and pulls the bin cover 21 to rotate, so that the bin cover 21 is covered on the shell 22. When the cover opening roller set 321 rolls along the trapezoidal guide plate 311, the bin cover 21 rotates, causing the elastic member 24 to be stretched. Once the cover opening roller set 321 is separated from the trapezoidal guide plate 311, the elastic member 24 will automatically reset due to its own elastic restoring force, pull the bin cover 21 to rotate and cover the shell 22. This design not only realizes the automatic resetting function of the bin cover 21, but also ensures that the bin cover 21 can be tightly covered on the shell 22 when not subjected to external force, preventing the articles from falling during the transmission process and improving the stability of the transmission of the articles.

[0034] Referring to Figure 2 and Figure 3 The transmission bin structure of the lifting system of the embodiment is further provided with an elastic member 24, one end of the elastic member 24 is connected with the bin cover 21, and the other end of the elastic member 24 is connected with the shell 22; when the cover opening roller set 321 rolls along the trapezoidal guide plate 311, the bin cover 21 rotates so that the elastic member 24 is in a stretched state; when the cover opening roller set 321 is separated from the trapezoidal guide plate 311, the elastic member 24 resets and pulls the bin cover 21 to rotate, so that the bin cover 21 is covered on the shell 22. When the cover opening roller set 321 rolls along the trapezoidal guide plate 311, the bin cover 21 rotates, causing the elastic member 24 to be stretched. Once the cover opening roller set 321 is separated from the trapezoidal guide plate 311, the elastic member 24 will automatically reset due to its own elastic restoring force, pull the bin cover 21 to rotate and cover the shell 22. This design not only realizes the automatic resetting function of the bin cover 21, but also ensures that the bin cover 21 can be tightly covered on the shell 22 when not subjected to external force, preventing the articles from falling during the transmission process and improving the stability of the transmission of the articles.

[0035] Referring to Figure 2 and Figure 3The elastic member 24 is a spring in the transmission bin structure of the lifting system of the embodiment. The spring can not only realize the reset function of the bin cover 21, but also buffer the direct friction and collision between the bin cover 21 and the shell 22.

[0036] Referring to Figure 2 and Figure 3 The transmission bin 2 is further provided with a positioning roller set 25 in the transmission bin structure of the lifting system of the embodiment. The positioning roller set 25 is arranged on the fourth plate body 224, and the cover opening roller set 321 and the positioning roller set 25 are respectively located at two ends of the fourth plate body 224. The cover opening assembly 3 further comprises a balance guide rail 33 arranged on the lifting support 1. The balance guide rail 33 and the guide component 31 are respectively located at two sides of the transmission belt 11. When the cover opening roller set 321 rolls on the guide component 31, the positioning roller set 25 moves on the balance guide rail 33, so that the transmission bin 2 moves stably on the transmission belt 11. The cover opening roller set 321 rolls on the guide component 31, and the positioning roller set 25 rolls on the balance guide rail 33, so that the movement of the transmission bin 2 on the transmission belt 11 is more stable. Through the joint action of the two independent guide systems, the shaking and deviation of the transmission bin during the movement can be effectively reduced.

[0037] Referring to Figure 4 The transmission bin 2 further comprises a baffle 26 connected with the first plate body 221, the second plate body 222 and the fourth plate body 224 respectively, so as to shield part of the inlet 23. When the transmission bin 2 operates from top to bottom, the baffle 26 is used to block the articles in the transmission bin 2 from sliding down. With the rotation of the transmission belt 11, the transmission bin 2 changes from the rising state to the downward moving state. At this time, the height of the inlet 23 is lower than that of the bin cover 21. The baffle 26 structure is arranged. When the articles (test tubes or liquid bags) in the transmission bin 2 fail to be unloaded in time during the rising process, the baffle 26 can block the articles from sliding down, so as to prevent the articles from falling into the bottom equipment body, and ensure the safety of the lifting equipment operation.

[0038] Referring to Figure 5The transmission bin structure of the lifting system of the embodiment, the transmission bin 2 is multiple, the cover opening assembly 3 is multiple, each transmission bin 2 and each cover opening assembly 3 are set one by one, multiple transmission bins 2 are arranged at intervals on the transmission belt 11, and multiple cover opening assemblies 3 are arranged at intervals on the lifting support 1; the transmission bin structure of the lifting system further comprises a slide 4, the slide 4 is connected with the lifting support 1, the slide 4 is multiple, each slide 4 is set one by one with each cover opening assembly 3, when the bin cover 21 is opened, the article in the transmission bin 2 slides into the slide 4. Multiple transmission bins 2 and multiple cover opening assemblies 3 are arranged at intervals on the transmission belt 11, so that the lifting system can process multiple articles in parallel, without waiting for a single transmission bin 2 to complete the entire process before proceeding to the next one, greatly improving the transmission efficiency. When the bin cover 21 of one transmission bin 2 is opened and the article slides into the slide 4, the other transmission bins 2 can continue to move on the transmission belt 11 and perform their respective work processes.

[0039] Referring to Figure 5 The height of the lifting support 1 of the embodiment is 15 meters. Taking the transmission of liquid bags as an example, when the lifting system is working, the liquid bags are lifted to the designated height by the transmission bin 2, and the cover opening assembly 3 and the slide 4 are arranged at each designated height. When the cover opening roller set 321 passes through the trapezoidal guide plate 311, the cover opening roller set 321 moves along the surface of the trapezoidal guide plate 311, and the height difference of the trapezoidal guide plate 311 pushes the bin cover 21 to open, and the liquid bag in the transmission bin 2 slides out under the action of gravity. When the cover opening roller set 321 on the bin cover 21 contacts the trapezoidal guide plate 311, it may cause the transmission bin 2 to shake, causing the bin body to be unstable and causing equipment failure. At this time, the positioning roller set 25 cooperates with the balance guide rail 33 to position the transmission bin 2, preventing shaking while also increasing the stability of the discharge. The liquid bag is mainly made of plastic materials such as PP and PE. The inside of the transmission bin 2 is coated with low-friction material, and the properties of the coating material can be smooth movement with materials such as PP and PE. This transmission bin 2 can be used specifically for the transportation of liquid bags.

[0040] The transmission bin 2 is installed and fixed at the reserved fixing plate 12 of the transmission belt 11, and the transmission bin 2 has an inclination angle to facilitate the sliding of the liquid bag, but the transmission bin 2 mounting plate 27 and the fixing plate 12 are horizontal (as shown in Figure 2 and Figure 3 After the transmission bin 2 is installed and fastened with the transmission belt 11, the transmission bin 2 and the transmission belt 11 move synchronously upward in a cycle to drive the liquid bag to be lifted.
