Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, and in particular to a sealing structure for a color sorter. Background Technology

[0002] During operation, although the camera is housed in the color sorter, the chassis has an openable door for easy assembly and maintenance. Moisture and dust in the air can enter the chassis through the door or window gaps, affecting the image quality of the color sorter and potentially causing serious damage to the components inside the chassis.

[0003] Existing color sorters typically use sealing rings between the casing and door to prevent dust and moisture from entering. However, the sealing structure used in some color sorters has high requirements for the materials of the equipment itself, making it prone to component damage. This can lead to sudden seal failure, and there is a possibility that the seal may not be completely closed when the machine is opened or closed, which can seriously affect normal production operations. If only the tension of a spring is used to maintain the seal, the vibration during the operation of the color sorter will cause the seal to become unstable. If bolts or other fixing methods are used to maintain the seal, opening and closing will be inconvenient. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a sealing structure for a color sorter, which solves the problems that sealing failure is sudden and that there may be situations where the seal is not completely closed due to human error when opening and closing.

[0005] The technical solution of this utility model is as follows:

[0006] A color sorter sealing structure includes a body and a sealing door. The body near the opening and one side of the sealing door are connected by a sealing assembly. The top of the inner cavity of the body drives the sealing door to open and close via an opening and closing assembly. A sealing component is provided between the body and the sealing door. The sealing component includes a telescopic cylinder. The top of the telescopic cylinder is rotatably connected to the top of the inner cavity of the body. An air extraction block is slidably connected to the inner wall of the telescopic cylinder. A telescopic rod is fixedly connected to one side of the air extraction block. The telescopic rod passes through the telescopic cylinder and can slide relative to the telescopic cylinder. One end of the telescopic rod is rotatably connected to one side of the sealing door. A small vent and a large vent are provided on one side of the telescopic cylinder. An air regulating assembly is provided around the large vent.

[0007] Preferably, the sealing assembly includes a sealing plate, the outer wall of which is connected to the inner wall of the machine body near the opening, a sealing groove is provided on one side of the sealing plate, and a sealing strip is fixedly connected to one side of the sealing door, the sealing strip engaging with the sealing groove.

[0008] Preferably, the opening and closing assembly includes a linkage folding plate. A fixing block is fixedly connected to the top of the inner cavity of the machine body and one side of the sealing door. A connecting plate is fixedly connected to one side of the fixing block. An upper rotating shaft and a lower rotating shaft are fixedly connected to the outer wall of the connecting plate. A driving plate is rotatably connected to the outer wall of the upper rotating shaft. A driving shaft is rotatably connected to one end of the driving plate. The outer wall of the driving shaft is rotatably connected to one end of the linkage folding plate. The other end of the linkage folding plate is rotatably connected to the outer wall of the lower rotating shaft. There are two linkage folding plates connected to the machine body and two connected to the sealing door. The two linkage folding plates are rotatably connected at their intersection through a linkage shaft. The linkage folding plate connected to the machine body is connected to the driving plate connected to the sealing door. The linkage folding plate connected to the sealing door is connected to the driving plate connected to the machine body.

[0009] Preferably, a spring is fixedly connected to one side of the vacuum block in the sealing assembly, and one end of the spring is fixedly connected to the inner wall of the telescopic cylinder. The spring is always kept in a slightly stretched state. The vacuum block divides the internal space of the telescopic cylinder into upper and lower parts. The upper part is always in a vacuum state, and the lower part is connected to the outside through a small vent and a large vent.

[0010] Preferably, the air regulating component includes a sealing patch, one side of the telescopic cylinder is fixedly connected to a portion of the sealing patch, and the other portion of the sealing patch can completely cover the large vent hole. The sealing patch is made of an elastic material and can be bent along the boundary line between the fixed and covered sections, always having elasticity in the straight direction.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] 1. This utility model utilizes the sliding cooperation of the suction block within the telescopic cylinder. Due to the pressure difference within the telescopic cylinder, the suction block can automatically adjust the pressure within the telescopic cylinder according to the opening and closing state of the sealing door. When the sealing door is open, the suction block slides downward, allowing the lower part of the telescopic cylinder to connect with the outside through small and large vent holes, increasing the pressure difference. When the sealing door is closed, the suction block moves upward under the action of the pressure difference, and the upper part always maintains a vacuum state, which helps to improve the sealing effect and keep the sealing door tightly closed.

[0013] 2. This utility model connects the sealing plate to the machine body near the opening. A sealing groove is opened on the sealing plate, and the sealing strip fixed on one side of the sealing door precisely engages with the sealing groove, forming a highly efficient sealing barrier. This effectively prevents external dust, debris, liquids and other impurities from entering the color sorter, creating a clean and stable working environment for key components such as optical elements. This ensures the stable and reliable color sorting performance of the color sorter and greatly reduces misidentification caused by impurities.

[0014] 3. This utility model, through the coordinated operation of the linkage folding plates, fixed blocks, connecting plates, upper rotating shafts, lower rotating shafts, driving plates, and driving shafts, enables the sealing door to operate smoothly and stably during opening and closing. Furthermore, the rotatable connection between the two linkage folding plates at their intersection via the linkage shaft, and their connection methods with different driving plates on the machine body and sealing door, further optimize the flexibility of opening and closing, facilitating daily maintenance, repair, and material loading and unloading operations for operators.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-8A color sorter sealing structure includes a body 1 and a sealing door 2. The body 1 near the opening and one side of the sealing door 2 are connected by a sealing assembly. The top of the inner cavity of the body 1 drives the sealing door 2 to open and close via an opening and closing assembly. A sealing assembly is provided between the body 1 and the sealing door 2. The sealing assembly includes a telescopic cylinder 3. The top of the telescopic cylinder 3 is rotatably connected to the top of the inner cavity of the body 1. An air extraction block 4 is slidably connected to the inner wall of the telescopic cylinder 3. A telescopic rod 5 is fixedly connected to one side of the air extraction block 4. The telescopic rod 5 passes through the telescopic cylinder 3 and can slide relative to the telescopic cylinder 3. One end of the telescopic rod 5 is rotatably connected to one side of the sealing door 2. A small vent 6 and a large vent 7 are provided on one side of the telescopic cylinder 3. An air regulating assembly is provided around the large vent 7.

[0026] Please see Figure 2-3 The sealing assembly includes a sealing plate 8, the outer wall of which is connected to the inner wall of the body 1 near the opening. A sealing groove 9 is provided on one side of the sealing plate 8, and a sealing strip 10 is fixedly connected to one side of the sealing door 2. The sealing strip 10 engages with the sealing groove 9. The sealing plate 8 is connected to the body 1 near the opening, and the sealing groove 9 is provided on the sealing plate 8. The sealing strip 10 fixed on one side of the sealing door 2 engages precisely with the sealing groove 9, forming a highly efficient sealing barrier. This effectively prevents external dust, debris, liquids and other impurities from entering the color sorter, creating a clean and stable working environment for key components such as optical elements. This ensures the stable and reliable color sorting performance of the color sorter, greatly reducing misidentification caused by impurities. The significance lies in providing a clean and stable working environment for key components such as optical elements inside the color sorter, avoiding the impact of impurities on the accuracy of optical imaging and color sorting judgment, thereby ensuring the color sorting performance of the color sorter, extending the service life of the equipment, and reducing equipment failure and maintenance costs caused by impurities.

[0027] Please see Figure 2-3 and Figure 8The opening and closing assembly includes a linkage folding plate 11. A fixing block 12 is fixedly connected to the top of the inner cavity of the body 1 and one side of the sealing door 2. A connecting plate 13 is fixedly connected to one side of the fixing block 12. An upper rotating shaft 14 and a lower rotating shaft 15 are fixedly connected to the outer wall of the connecting plate 13. A driving plate 16 is rotatably connected to the outer wall of the upper rotating shaft 14. A driving shaft 17 is rotatably connected to one end of the driving plate 16. The outer wall of the driving shaft 17 is rotatably connected to one end of the linkage folding plate 11. The other end of the linkage folding plate 11 is rotatably connected to the outer wall of the lower rotating shaft 15. Two linkage folding plates 11 are connected to the body 1 and two are connected to the sealing door 2. The intersection of the two linkage folding plates 11 is rotatably connected via a linkage shaft. The linkage folding plate 11 connected to the body 1 is connected to the driving plate 16 connected to the sealing door 2. The linkage folding plate 11 is connected to the drive plate 16 connected to the machine body 1. Through the coordinated operation of the linkage folding plate 11, the fixed block 12, the connecting plate 13, the upper rotating shaft 14, the lower rotating shaft 15, the drive plate 16, and the drive shaft 17, the sealing door 2 moves smoothly and stably during opening and closing. The two linkage folding plates 11 are rotatably connected by the linkage shaft at their intersection, and their connection methods with the different drive plates 16 on the machine body 1 and the sealing door 2 further optimize the flexibility of opening and closing, making it convenient for operators to perform daily maintenance, repair, and material loading and unloading operations. The significance is to improve the convenience and efficiency of the color sorter, reduce the waste of operation time caused by inconvenient opening and closing, and at the same time, the stable opening and closing structure can also reduce the wear of sealing components caused by frequent opening and closing, further ensuring the sealing performance.

[0028] Please see Figure 4-7A spring 18 is fixedly connected to one side of the vacuum block 4 in the sealing assembly. One end of the spring 18 is fixedly connected to the inner wall of the telescopic cylinder 3. The spring 18 is always in a slightly stretched state. The vacuum block 4 divides the internal space of the telescopic cylinder 3 into upper and lower parts. The upper part is always in a vacuum state, and the lower part is connected to the outside through a small vent 6 and a large vent 7. Its function is to dynamically adjust the pressure in the sealed space, which is of great significance in improving the stability and reliability of the sealing structure and ensuring that the color sorter can maintain a good sealing state under different working conditions, thus ensuring the accuracy of color sorting. The air regulating assembly includes a sealing patch 19. One side of the telescopic cylinder 3 is fixedly connected to a part of the sealing patch 19, and the other part is sealed. The patch 19 can completely cover the large vent 7. The sealing patch 19 is made of elastic material and can bend along the boundary between the fixed and covered parts, always having elasticity in the straight direction. Through the sliding cooperation of the suction block 4 in the telescopic cylinder 3, due to the air pressure difference in the telescopic cylinder 3, the suction block 4 can automatically adjust the pressure in the telescopic cylinder 3 according to the opening and closing state of the sealing door 2. When the sealing door 2 is open, the suction block 4 slides downward, so that the lower part of the telescopic cylinder 3 is connected to the outside through the small vent 6 and the large vent 7, increasing the pressure difference. When the sealing door 2 is closed, the suction block 4 moves upward under the action of the air pressure difference, and the upper part always maintains a vacuum state, which helps to improve the sealing effect and keep the sealing door 2 tightly closed.

[0029] Working principle of this utility model:

[0030] When maintenance or repair of the color sorter is required, the operator pulls the sealing door 2 outward. At this time, the opening and closing assembly begins to function. The upper rotating shaft 14 on the connecting plate 13, which is connected to the fixed block 12 on one side of the sealing door 2, drives the driving plate 16 to rotate. The driving plate 16, through the driving shaft 17, causes the linkage folding plate 11 to rotate around the linkage shaft. At the same time, the linkage folding plate 11 connected to the machine body 1 and the driving plate 16 connected to the sealing door 2 cooperate with each other, so that the sealing door 2 can be opened smoothly and flexibly. During the opening process, the air extraction block 4 in the sealing assembly slides downward against the slight tension of the spring 18 under the action of the telescopic rod 5 driven by the rotation of the sealing door 2. The air extraction block 4 divides the internal space of the telescopic cylinder 3 into upper and lower parts. The upper part is always in a vacuum state, and the lower part is connected to the outside through the small vent 6 and the large vent 7. As the air extraction block 4 slides down, the space in the lower part gradually decreases, and air is discharged through the large and small vents 6. The gas blows the sealing patch 19, bending it without blocking the large vent 7. The air is discharged quickly, and the vacuum space in the telescopic cylinder 3 gradually increases. After maintenance or repair, the operator closes the sealing door 2. When the sealing door 2 is closed, the sealing strip 10 of the sealing component and the sealing groove 9 on the sealing plate 8 precisely engage to form a tight sealing structure, effectively preventing external dust, debris, liquid and other impurities from entering the color sorter. At the same time, in the sealing component, due to the air pressure difference in the telescopic cylinder 3, the air extraction block 4 slides upward, and the space connecting the lower part of the telescopic cylinder 3 with the outside gradually increases, allowing air to enter. At this time, when the sealing patch 19 completely covers the large vent 7, only the small vent 6 connects with the outside, slowing down the airflow speed; that is, the closing speed of the sealing door 2 decreases, which does not affect manual maintenance. After the sealing door 2 is completely closed, the air pressure difference in the telescopic cylinder 3 always provides an inward pulling force, keeping the sealing door 2 tightly closed, providing a good working environment for key components such as optical elements inside the color sorter, and ensuring that the color sorter completes material screening work efficiently and accurately.
