Description

Technical Field

[0001] This utility model belongs to the field of loading and unloading technology, and in particular relates to an unloading device. Background Technology

[0002] Unloading devices are mainly used to control the discharge of materials, ensuring that materials are discharged from storage silos, hoppers, or pipelines as needed, in a quantitative manner, continuously or intermittently. They are widely used in industrial production, material conveying, and automated processes. Currently, under certain production conditions, unloading devices need to have a quantitative discharge function. Quantitative unloading ensures that the amount of materials discharged each time meets process requirements (such as batching and packaging), and plays an important role in industrial production.

[0003] Current quantitative unloading devices are complex in structure because they require weighing sensors or flow meters to calculate the amount of material. In addition, the opening and closing valves for unloading material need to use different power sources to achieve different opening and closing states, making it difficult to achieve linkage. This results in high manufacturing costs and energy consumption costs during production, which is not conducive to improving the production efficiency of the production line. This problem urgently needs to be solved. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a unloading device to solve the problems of high manufacturing cost and high energy consumption cost during production of the quantitative unloading device in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a unloading device, including a first gate, a second gate, and a hopper. The hopper has an inlet and an outlet. The first gate and the second gate are sequentially arranged on the hopper along a first direction, which is the direction from the inlet to the outlet. Both the first gate and the second gate are used to control the unloading of materials in the hopper. A driving component is connected to the first gate and the second gate respectively. The driving component drives the first gate and the second gate to move along a second direction, which intersects with the first direction. The driving component has an unloading position and a feeding position. When the driving component is located at the unloading position, the first gate is located on the flow trajectory of the materials and blocks the materials from flowing through the first gate, while the second gate is located outside the flow trajectory of the materials. When the driving component is located at the feeding position, the second gate is located on the flow trajectory of the materials and blocks the flow of the materials, while the first gate is located outside the flow trajectory of the materials.

[0006] Optionally, the driving component includes a linkage, a first connector, and a second connector. The first connector is connected to the linkage and the first gate, respectively, and the second connector is connected to the linkage and the second gate, respectively. The hopper is located between the first connector and the second connector.

[0007] Optionally, the linkage is located at the top of the hopper.

[0008] Optionally, the drive assembly further includes a mounting bracket, a drive shaft seat mounted on the mounting bracket, and a power output component connected to the linkage component. The linkage component is rod-shaped and passes through the drive shaft seat. The linkage component reciprocates along the axial direction of the linkage component under the drive of the power output component.

[0009] Optionally, the drive shaft seat has a receiving cavity for accommodating lubricant, the receiving cavity being located on the passing trajectory of the linkage member, the drive shaft seat having an inlet and outlet opening for the linkage member to pass through, and a first sealing component for sealing the gap between the linkage member and the drive shaft seat being provided at each of the inlet and outlet openings.

[0010] Optionally, the power output component is a cylinder, and a reset spring is provided inside the cylinder for resetting. The reset spring is used to drive the piston of the cylinder to move toward the gas inlet of the cylinder.

[0012] Optionally, the first gate includes a first blocking part for blocking the material from passing through, and the second gate includes a second blocking part for blocking the material from passing through and a second discharging part for the material to pass through. The second discharging part has a passing structure. The second blocking part and the second discharging part are connected. When the driving component is located at the feeding position, the first blocking part is located outside the flow path of the material, and the second blocking part is located on the flow path of the material, blocking the material from flowing through the second blocking part. When the driving component is located at the unloading position, the first blocking part is located on the flow path of the material, blocking the material from flowing through the first blocking part, and the second discharging part is located on the flow path of the material, and the material flows through the second discharging part through the passing structure.

[0013] Optionally, the passage structure is a through hole that penetrates the second gate along the first direction.

[0015] As described above, the unloading device of this utility model has the following beneficial effects:

[0016] The first and second gates use the same drive assembly for unloading, which saves energy and reduces production costs. At the same time, when the drive assembly is in the feeding position, the material on the first gate can fall into the space between the first and second gates in the hopper. When the drive assembly is in the unloading position, the material between the first and second gates in the hopper can be unloaded to achieve the purpose of quantitative unloading.

Therefore, they have no substantial technical significance.

[0025] In order to describe this utility model in detail, the following is a specific description of a material unloading device of this utility model:

[0026] Please combine Figure 1 and Figure 4 As shown, this utility model provides a unloading device, including a first gate 11, a second gate 12, and a hopper 10. The hopper 10 has an inlet and an outlet. The first gate 11 and the second gate 12 are sequentially arranged on the hopper 10 along a first direction, which is the direction from the inlet to the outlet. The first gate 11 and the second gate 12 are both used to control the unloading of materials in the hopper 10. A driving component is connected to the first gate 11 and the second gate 12 respectively. The driving component drives the first gate 11 and the second gate 12 to move along a second direction, which intersects with the first direction. The driving component has an unloading position and a feeding position. When the driving component is in the unloading position, the first gate 11 is located on the flow trajectory of the materials and blocks the materials from flowing through the first gate 11. The second gate 12 is located outside the flow trajectory of the materials. When the driving component is in the feeding position, the second gate 12 is located on the flow trajectory of the materials and blocks the materials from flowing. The first gate 11 is located outside the flow trajectory of the materials. The first gate 11 and the second gate 12 use the same drive assembly for unloading, which can save energy and reduce production costs. At the same time, when the drive assembly is in the feeding position, the material on the first gate 11 can fall into the space between the first gate 11 and the second gate 12 in the hopper 10. When the drive assembly is in the unloading position, the material between the first gate 11 and the second gate 12 in the hopper 10 can be unloaded to achieve the purpose of quantitative unloading.

[0027] In this embodiment, the first direction and the second direction are perpendicular, which reduces the travel distance of the first gate 11 and the second gate 12 during movement and results in a neat and aesthetically pleasing appearance. Additionally, the hopper has a square cross-section, making assembly and arrangement more convenient.

[0028] The drive assembly includes a linkage 6, a first connecting member 8, and a second connecting member 7. The first connecting member 8 is connected to both the linkage 6 and the first gate 11, and the second connecting member 7 is connected to both the linkage 6 and the second gate 12. The hopper 10 is located between the first connecting member 8 and the second connecting member 7. The first gate 11 and the second gate 12 are respectively inserted on opposite sides of the hopper 10. Quantitative unloading is achieved through this method, eliminating the need for weighing sensors or flow meters to calculate material quantities. The structure is simple, the manufacturing cost is low, and it offers good economic benefits.

[0029] The linkage 6 is located at the top of the hopper 10, which makes reasonable use of the upper space of the hopper 10 and avoids the unloading device occupying a large area of ​​the ground, which would be easily limited by the installation space.

[0030] Specifically, the unloading device also includes a mounting frame 2, a transmission shaft seat 4 mounted on the mounting frame 2, and a power output component 1 connected to the linkage component 6. The linkage component 6 is rod-shaped and passes through the transmission shaft seat 4. The linkage component 6 reciprocates along the axial direction of the linkage component 6 under the drive of the power output component 1. In this embodiment, the power output component 1 is a cylinder. When gas is introduced into the cylinder, the piston rod drives the drive assembly from the feeding position to the unloading position. A reset spring 102 is provided in the cylinder for resetting. The reset spring 102 drives the piston 101 of the cylinder to move towards the gas inlet of the cylinder. Thus, after gas enters the cylinder, the piston rod can drive the drive assembly from the unloading position to the feeding position through the reset spring 102, realizing the automatic reset function and further reducing energy consumption. The piston rod of the cylinder is connected to the linkage 6 via a coupling 3 to extend the working length of the piston rod, facilitating connection between the cylinder and the first gate 11 and the second gate 12. The piston rod of the cylinder drives the first gate 11 and the second gate 12 to move. In some embodiments, when gas is introduced into the cylinder, the piston rod drives the drive assembly from the discharge position to the feed position. When the gas supply to the cylinder stops, the drive assembly moves from the feed position to the discharge position under the action of the return spring 102. In other embodiments, the power output component 1 is a linear motor. The type of power output component 1 can be adjusted according to actual usage needs. The space between the first gate 11 and the second gate 12 in the hopper 10 is a material accumulation space. In this embodiment, when the first gate 11 exits from the hopper 10, the workpiece passes through the first gate 11 of the hopper 10. At this time, the second gate 12 enters the hopper 10 and is located on the flow path of the workpiece, blocking the workpiece from flowing out of the hopper 10, thus driving the component to the feeding position, and a certain amount of workpiece can be accumulated in the accumulation space. When the first gate 11 enters the hopper 10 and is located on the flow path of the workpiece, blocking the workpiece from flowing through the first gate 10, the second gate 12 exits from the hopper 10, allowing the workpiece to pass through. The second gate 12 drives the assembly to the unloading position, at which point the material accumulated in the accumulation space is unloaded. It should be noted that if the material is powdery or granular, the actual unloading amount is greater than the original accumulated material because it takes time for the first gate 11 to completely block the material from entering the accumulation space. However, since the first gate 11 moves at the same speed in the hopper 10 each time, the extra unloaded material is approximately the same each time, thus it can be considered as a quantitative unloading device. If the material in the hopper 10 is large-particle material, and there is only one large-particle material at any position in the hopper 10 along the first direction, then in this case, the unloading device can achieve quantitative unloading, which is different from the approximate quantitative unloading of non-powder materials.

[0031] like Figure 3As shown, in this embodiment, the drive shaft seat 4 has a receiving cavity 401 for accommodating lubricant. The receiving cavity 401 is located on the path of the linkage 6. The drive shaft seat 4 has inlet and outlet openings for the linkage 6 to pass through. A first sealing component 5 is provided at each inlet and outlet opening to seal the gap between the linkage 6 and the drive shaft seat 4. By providing a receiving cavity 401 for accommodating lubricant, the smoothness of the linkage 6 when driving the first gate 11 and the second gate 12 can be ensured, and the linkage 6 can be prevented from becoming worn and jammed during movement after repeated use. The first sealing component 5 includes a nylon seat 501 and a first sealing ring 502. The nylon seat 501 blocks the two inlet and outlet openings of the drive shaft seat 4 respectively. A first sealing ring 502 is provided between the nylon seat 501 and the linkage 6 on the side of the nylon seat 501 away from the drive shaft seat 4.

[0032] like Figure 2 As shown, in this embodiment, if the hopper 10 stores powdery or granular materials, considering that the first gate 11 will encounter significant resistance from the powdery or granular materials when entering the hopper 10, the end of the first gate 11 facing the inner wall of the hopper in the second direction is wedge-shaped or V-shaped. This reduces the resistance encountered by the first gate 11 when entering the hopper 10. Simultaneously, the first gate 11 and the second gate 12 are installed on the hopper 10. A second sealing component 9 is provided on the outer surface of the hopper 10 where the first gate 11 and the second gate 12 are installed. The second sealing component 9 is used to seal the gap between the first gate 11 or the second gate 12 and the hopper 10. By providing the second sealing component 9, it is possible to prevent the powdery or granular materials from being carried out of the hopper 10 during the process of the first gate 11 and the second gate 12 entering and exiting the hopper 10. The second sealing assembly 9 includes a sealing base 901 and a second sealing ring 902. The sealing base 901 is bolted to the outer surface of the hopper 10, and the second sealing ring 902 is fitted onto the first gate 11 or the second gate 12. The hopper 10 has an insertion port for inserting the first gate 11 and the second gate 12. A receiving groove for accommodating the third sealing ring 903 is formed on the side wall of the insertion port. The receiving groove surrounds the side wall of the insertion port axially, and the third sealing ring 903 is disposed within the receiving groove to fill the gap between the insertion port and the first gate 11 or the second gate 12. A sealing gasket 13 is provided on the surface of the second gate 12 facing the inner wall of the hopper 10 in the second direction. The sealing gasket 13 can be disposed within a groove on the second gate 12 or adhered to the second gate 12 to prevent powdery or small granular materials from leaking out of the hopper 10.

[0033] like Figure 5As shown, in some embodiments, the driving component includes a third connector 14, which is connected to the first gate 11 and the second gate 12 respectively. The power output component 1 is used to drive the third connector 14 to move, thereby driving the first gate 11 and the second gate 12 to move. The first gate 11 and the second gate 12 are both connected to the third connector 14, which can further save the material cost of manufacturing the unloading device. The first gate 11 includes a first blocking part for blocking the passage of workpiece material, and the second gate 12 includes a second blocking part for blocking the passage of workpiece material and a second discharge part for allowing the workpiece material to pass through. The second discharge part has a passing structure. The second blocking part and the second discharge part are connected. When the driving component is in the feeding position, the first blocking part is located outside the flow path of the workpiece material, allowing the workpiece material to flow through the first gate. The second blocking part is located on the flow path of the workpiece material and blocks the workpiece material from flowing through the second blocking part. When the driving component is in the unloading position, the first blocking part is located on the flow path of the workpiece material and blocks the workpiece material from flowing through the first blocking part. The second discharge part is located on the flow path of the workpiece material, and the workpiece material flows through the second discharge part through the passing structure. The passing structure is a passing hole penetrating the second gate 12 along a first direction, which facilitates production and manufacturing. The passing structure can also be multiple parallel passing slots or multiple passing holes penetrating the second gate 12. The type of passing structure can be adjusted according to the actual application. Because the second gate 12 is provided with a second blocking part and a second discharge part for the working material, the hopper 10 has an inlet for inserting the second gate 12 and an outlet for removing the second blocking part from the hopper 10. The inlet and outlet on the hopper 10 are arranged opposite to each other. When the drive assembly is in the feeding position, the first gate 11 is outside the flow path of the working material in the hopper 10, and the second blocking part of the second gate 12 is on the flow path of the working material in the hopper 10. When the drive assembly moves from the feeding position to the unloading position, the first gate 11 enters the hopper 10 in the second direction. At this time, the second blocking part of the second gate 12 exits the hopper 10 through the outlet of the hopper 10, and the second discharge part of the second gate 12 enters the hopper 10.

[0034] In other embodiments, the driving component includes a linkage 6 and two third connecting members 14 respectively connected to the linkage 6. Each third connecting member 14 is respectively disposed corresponding to the first gate 11 and the second gate 12. One third connecting member 14 is connected to the first gate 11, and the other third connecting member 14 is connected to the second gate 12. Both third connecting members 14 are disposed on the same side of the hopper 10. The arrangement of the driving component can be adjusted according to actual needs.

[0035] In summary, the first gate 11 and the second gate 12 use the same drive assembly for quantitative unloading, which saves energy and reduces production costs. At the same time, when the drive assembly is in the feeding position, the material on the first gate 11 can fall into the space between the first gate 11 and the second gate 12 in the hopper 10. When the drive assembly is in the unloading position, the material between the first gate 11 and the second gate 12 in the hopper 10 can be unloaded to achieve the purpose of quantitative unloading.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
