Description

Technical Field

[0001] The invention belongs to the technical field of material transmission, and in particular relates to a quantitative feeding mechanism and a conveyor. Background Art

[0002] The main purpose of paint filling weighing is to ensure accurate measurement and filling of paint products to meet customer requirements for accuracy and consistency of paint quantity. Traditionally, paint filling equipment will install a weighing device under the paint outlet. During operation, the paint bucket is first placed on the weighing device, and then the outlet valve is manually opened. The paint flows into the paint bucket from the outlet, and the reading of the weighing device begins to change. Once the reading reaches the preset range, the staff needs to manually close the outlet valve. This mode of operation relies on manual control of the opening and closing of the valve, and the degree of automation is relatively low.

[0003] With the continuous advancement of automation technology, technicians have introduced PLC control systems to optimize this process. While weighing, the system can capture the weight changes of the paint bucket in real time through gravity sensing and transmit these sensing signals to the control system. The control system automatically controls the opening and closing of the valve based on this, thus realizing the automation of the filling process.

[0004] However, although this method effectively solves the problem of manual operation of valve opening and closing, due to the complexity of the equipment structure and the high cost of the control system, the overall production cost increases, the economic benefits are affected, and there are certain application limitations. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a quantitative feeding mechanism and a conveyor to solve the technical problems in the prior art of manually controlling the opening and closing of valves, the relatively low degree of automation, and the high production and maintenance costs of the control system controlling the valve shutdown.

[0006] One of the present inventions: In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is a quantitative feeding mechanism, comprising: Rotating a seal connected to the discharge port; A carrier, the carrier being used to carry a material container; A transmission assembly, the transmission assembly is arranged between the carrier and the sealing member, and the transmission assembly drives the sealing member to rotate during the downward movement of the carrier so as to gradually close the discharge port, and drives the sealing member to rotate in the opposite direction during the upward movement of the carrier so as to gradually open the discharge port; An elastic support structure is arranged below the supporting member. When the material container gradually collects the material discharged from the silo discharge port, the supporting member moves downward to compress the elastic support structure. At the same time, the sealing member is driven to rotate under the action of the transmission component to gradually close the discharge port, until the material in the material container reaches a preset weight, and the sealing member completely closes the silo discharge port.

[0007] Compared with the prior art, the advantages of the present invention include: (1) The quantitative feeding mechanism provided by the present invention has a relatively simple structure and does not have a complex electronic control system or sensor, which reduces the maintenance cost of the mechanism and improves its stability and reliability. In harsh production environments, this simple and stable mechanism has more advantages.

[0008] (2) The quantitative feeding mechanism provided by the present invention has a sealing member that gradually closes the discharge port during the downward movement of the supporting member, so that the discharge speed of the discharge port is gradually reduced, so that the discharge speed of the discharge port is positively correlated with the weight increase of the contained material. When the discharge speed is closer to the preset weight, the discharge speed of the discharge port is smaller, thereby reducing the error caused by the large discharge port speed when closing the discharge port, thereby increasing the accuracy of the material weight in the material container.

[0009] (3) The quantitative feeding mechanism provided by the present invention links the feeding control with the material weighing through a transmission mechanism, thereby realizing automatic operation without the need for frequent human intervention, thereby reducing labor costs and improving the degree of automation of the production line, while also reducing the errors and uncertainties caused by human operation.

[0010] (4) The present invention provides a quantitative feeding mechanism. The design of the elastic support structure enables the mechanism to sense the weight change of the material in the material container. When the material reaches a preset weight, the elastic support structure is compressed to the limit (that is, the elastic support force provided by the elastic support structure is balanced with the weight of the material), and the seal automatically closes the discharge port, thereby achieving more precise control of the material weight. The elastic support structure can also realize the reset of the mechanism to form a cyclic operation, further improving automation.

[0011] (5) The quantitative feeding mechanism provided by the present invention can significantly improve production efficiency due to the realization of automated operation and relatively precise control. On a continuous production line, this feeding mechanism is of great significance for improving the production capacity and efficiency of the entire production line.

[0012] Further, the elastic support structure includes a support frame, on which a plurality of sleeves arranged along the vertical direction are installed, the sleeve is a hollow cylindrical structure with an open top, a sliding block is arranged in the sleeve and slides and seals along the inner wall of the sleeve, a support rod is arranged between the sliding block and the bearing member, the lower end of the support rod is connected to the sliding block, and the upper end is connected to the bottom of the bearing member; A connecting block is arranged between the plurality of sleeves. The connecting block is a hollow structure. The connecting block is respectively connected with the bottoms of the plurality of sleeves. A vent is arranged on the connecting block, and a valve is arranged on the vent.

[0013] In the present invention, the above structure has the following beneficial effects: (1) Multiple sleeves are connected through a connecting block to form an integral closed gas chamber inside. When the bearing is in an inclined state, that is, when its supporting surface is not kept horizontal, the support rod at a higher position will be subjected to force first and compress the corresponding sliding block to move downward, resulting in an increase in the pressure inside the gas chamber, thereby pushing other support rods to move upward until the tops of multiple support rods maintain the same horizontal position. And because the interiors of multiple sleeves are interconnected through the connecting block, the gas pressure on each support rod is consistent, and the elastic supporting force provided is also the same, which enables the bearing to maintain a horizontal state and provide consistent supporting force through each support rod, so that its support is stable.

[0014] (2) By providing vents and valves, the gas pressure in the chamber can be adjusted to provide different elastic supporting forces. Thus, when the supporting member descends to the same horizontal position, the weight of the material in the container will be different due to the different elastic supporting forces, so that it can adapt to containers of different models.

[0015] Furthermore, a positioning and clamping assembly is provided on the support frame, and the positioning and clamping assembly includes two positioning and clamping units symmetrically distributed on both sides of the material container; Each of the positioning and clamping units comprises a horizontally arranged mounting sleeve, each of the mounting sleeves is fixedly connected to the support frame, and each of the mounting sleeves is plugged with a sliding rod slidably connected to the mounting sleeve at one end close to the material container, and each of the sliding rods is provided with a V-shaped clamping rod at one end close to the material container, and when the two sliding rods slide relative to or away from each other, the two V-shaped clamping rods are respectively close to or away from the material container; A spring is arranged in each of the installation sleeves, and the two ends of the spring are respectively connected to the slide bar and the end of the installation sleeve away from the material container, and the two springs respectively push the two slide bars to make relative movements so that the two V-shaped clamping rods approach the material container and gradually clamp the material container; A pull rope is arranged between the supporting member and the two sliding rods, one end of the pull rope is connected to the end of the sliding rod away from the V-shaped clamp rod, and the other end extends in the direction away from the V-shaped clamp rod, passes through the installation sleeve and is connected to the supporting member. When the supporting member moves downward, the two sliding rods can be pulled by the two pull ropes to move in opposite directions so that the two V-shaped clamp rods are away from the material container and gradually release the clamping of the material container.

[0016] In the present invention, the above structure has the following beneficial effects: (1) The design of the positioning clamping assembly prevents the material container from moving or tilting during the material collection process.

[0017] (2) The V-shaped clamp rod can not only clamp the material container, but also guide the material container to the middle position of the V-shaped clamp rod through its V-shaped design so that it has a positioning function.

[0018] (3) The design of the pull rope enables the positioning and clamping assembly to automatically adjust the clamping state of the clamping assembly according to the changes in the material in the material container on the support. When no material is contained, the positioning and clamping assembly provides a positioning and clamping function; after the material is contained, the overall weight of the material container increases due to the increase in material, and the material container is more stable on the support and less likely to deviate or tip over, so the role of the clamping assembly is not significant. At the same time, in order to facilitate the subsequent replacement of the material container, the clamping assembly should release the clamping of the material container. At this time, the downward movement of the support will pull the two sliding rods to move in opposite directions through the pull rope so that the two V-shaped clamping rods release the clamping of the material container, thereby linking the material weighing with the positioning and clamping, which is more convenient to operate and has a high degree of automation.

[0019] Furthermore, the seal is a hollow cylindrical structure with one end open, the seal is sleeved outside the discharge port and can rotate relative to the discharge port, and the seal is provided with a flow port away from the other end, and by rotating the seal, the flow port coincides with or is staggered with the discharge port.

[0020] Furthermore, the transmission assembly includes a rack and a gear ring sleeved on the outside of the seal, wherein one end of the rack is hinged to the bearing member, and the other end vertically extends upward and meshes with the gear ring; The bearing member is provided with an elastic member, through which the rack and the gear ring are always kept in meshing state.

[0021] Furthermore, the transmission assembly includes a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged to the bearing member, the other end of the first connecting rod extends upward and is movably connected to one end of the second connecting rod in a detachable manner, and the other end of the second connecting rod is fixedly connected to the sealing member.

[0022] The second of the present invention: A conveyor, comprising the above-mentioned quantitative feeding mechanism; A first conveying mechanism, which is disposed above the carrier and can move up and down with the carrier, and is used to transport the material container, and is provided with a first transmission member; The second conveying mechanism is provided with a second transmission member. When the material container is filled with a given material, the first conveying mechanism is lowered to a position at the same level as the second conveying mechanism, and the first transmission member and the second transmission member act to enable the second conveying mechanism to drive the first conveying mechanism to operate.

[0023] In the present invention, the second conveying mechanism can be used to convey the packed materials, thus saving the labor cost of manual transportation, and the first conveying mechanism and the second conveying mechanism are linked together through the first transmission member and the second transmission member. When a preset weight of material is added to the material container (the first conveying mechanism and the second conveying mechanism are at the same horizontal position), the first transmission assembly and the second transmission assembly will take effect, so that the second conveying mechanism drives the first conveying mechanism to operate, and directly conveys the material container filled with the given material to the next process, with a high degree of automation.

[0024] Furthermore, the conveyor also includes a third conveying mechanism, on which a third transmission member is provided, and on which a fourth transmission member is provided. When the material container is filled with a given material, the first conveying mechanism, the second conveying mechanism and the third conveying mechanism are all maintained at the same horizontal position, and the third transmission member and the fourth transmission member act so that the first conveying mechanism drives the third conveying mechanism to operate.

[0025] In the present invention, the empty material container can be transported through the third conveying mechanism, which saves the labor cost of manual transfer, and the first conveying mechanism, the second conveying mechanism and the third conveying mechanism are linked together through the third transmission member and the fourth transmission member. When a preset weight of material is added to the material container (the first conveying mechanism, the second conveying mechanism and the third conveying mechanism are at the same horizontal position), the second conveying mechanism drives the first conveying mechanism to operate and transport the material container filled with the given material to the next process. At the same time, under the action of the third transmission member and the fourth transmission member, the first conveying mechanism drives the third conveying mechanism to operate and transport the empty material container to the first conveying mechanism, thereby reducing the process of manually replacing the empty material container, saving labor, and further improving the degree of automation.

[0034] One of the present inventions: See also Figure 1-3 The present invention provides a technical solution: a quantitative feeding mechanism, including a sealing member 1, a bearing member 2, a transmission assembly and an elastic supporting structure.

[0035] Among them, the seal 1 is rotatably connected to the end of the discharge port 27, and the seal 1 is used to control the opening and closing of the discharge port 27. The seal 1 needs to be able to effectively prevent the material from flowing out when the discharge port 27 is closed, and allow the material to be discharged smoothly from the discharge port 27 when it is opened.

[0036] The support member 2 is used to support the material container 28. Specifically, in this embodiment, in order to better perform the support function and reduce the weight of the support member 2, the support member 2 is designed to be a plate-like structure and is arranged horizontally. However, this does not mean that the support member 2 can only be a plate-like structure. Other structures that have a support function should also be within the protection scope of the present invention.

[0037] The transmission component is arranged between the carrier 2 and the seal 1. Through the transmission component, the seal 1 is driven to rotate during the downward movement of the carrier 2 to gradually close the discharge port 27. During the upward movement of the carrier 2, the seal 1 is driven to rotate in the opposite direction to gradually open the discharge port 27.

[0038] The elastic support structure is arranged below the supporting member 2 to play a supporting and buffering role. When the material container 28 gradually collects the material discharged from the silo outlet 27, the supporting member 2 moves downward and compresses the elastic support structure. At the same time, the sealing member 1 is driven to rotate under the action of the transmission component to gradually close the outlet 27. In this process, the compression degree of the elastic support structure will reflect the weight of the material in the material container 28. Therefore, when the material in the material container 28 reaches a preset weight, the sealing member 1 completely closes the silo outlet 27, and the elastic support force provided by the elastic support structure is in a state of equilibrium with the gravity of the material.

[0039] Before the mechanism starts working, the seal 1 is usually in an open state, allowing the material to be discharged freely from the silo discharge port 27. The carrier 2 and the material container 28 are in the initial position, and the elastic support structure is not compressed. When the mechanism starts working, the material is discharged from the silo discharge port 27 and falls into the material container 28. As the material accumulates, the weight of the material container 28 gradually increases, causing the carrier 2 to move downward. During the downward movement of the carrier 2, the first transmission assembly converts this movement into the rotation of the seal 1. As the carrier 2 continues to move downward, the seal 1 gradually rotates and closes the discharge port 27, thereby reducing the discharge amount of the material. The elastic support structure is gradually compressed during the downward movement of the carrier 2. This compression process will reflect the weight of the material in the material container 28. When the material reaches the preset weight, the compression of the elastic support structure reaches the limit (that is, the elastic support force provided by the elastic support structure and the material gravity are in a state of equilibrium), at which time the seal 1 completely closes the discharge port 27 and stops the material discharge. After the material is discharged, the material container 28 can be manually removed, the elastic support structure is elastically reset, and the sealing member 1 is driven to rotate in the opposite direction through the transmission component to gradually reopen the discharge port 27. A new material container 28 can be replaced for the next material discharge.

[0040] When the present invention is implemented in a specific application: ①. The feeding control is linked with the material weighing through the transmission mechanism, realizing automatic operation without frequent manual intervention, thereby reducing labor costs, improving the automation level of the production line, and also reducing the errors and uncertainties caused by manual operation; ②, during the downward movement of the carrier 2, the sealing member 1 gradually closes the discharge port 27, so that the discharge speed of the discharge port 27 is gradually reduced, so that the discharge speed of the discharge port 27 is in a positive correlation with the weight increase of the contained material. When the weight is closer to the preset weight, the discharge speed of the discharge port 27 is smaller, which reduces the error caused by the high speed of the discharge port 27 when closing the discharge port 27, thereby increasing the accuracy of the weight of the material in the container 28; ③. The design of the elastic support structure enables the mechanism to sense the weight change of the material in the material container 28. When the material reaches the preset weight, the elastic support structure is compressed to the limit (that is, the elastic support force provided by the elastic support structure is balanced with the material gravity), and the seal 1 automatically closes the discharge port 27, thereby achieving more precise control of the material weight.

[0041] See also Figure 2 and 3 In this embodiment: the elastic support structure includes a support frame 3, which serves as the foundation of the entire elastic support structure and provides a stable support platform. A plurality of sleeves 4 arranged along the vertical direction are installed on the support frame 3. The sleeve 4 is a hollow cylindrical structure with an open top. A sliding block 5 is arranged inside the sleeve 4 and is slidably sealed along the inner wall of the sleeve 4. The hollow design forms a track for the sliding block 5 to slide inside the sleeve 4. The vertical direction of the sleeve 4 allows the sliding block 5 to slide up and down along the inner wall of the sleeve 4. The sliding seal prevents gas leakage during the sliding process.

[0042] A support rod 6 is arranged between the sliding block 5 and the supporting member 2. The lower end of the support rod 6 is connected to the sliding block 5, and the upper end of the support rod 6 is connected to the bottom of the supporting member 2. The support rod 6 is a key component connecting the sliding block 5 and the supporting member 2. It transfers the force exerted on the supporting member 2 to the sliding block 5, so that the sliding block 5 can move with the movement of the supporting member 2.

[0043] A connecting block 7 is provided between the multiple sleeves 4. The connecting block 7 is a hollow structure. The connecting block 7 is connected to the bottom of the multiple sleeves 4 respectively, so that a closed gas chamber is formed inside. When the sliding block 5 moves up and down, the gas chamber will expand or shrink accordingly. When the support member 2 is in an inclined state, that is, when its supporting surface is not kept horizontal, the support rod 6 at a higher position will be subjected to force first, and compress the corresponding sliding block 5 to move downward, resulting in an increase in the pressure inside the gas chamber, thereby pushing other support rods 6 to move upward until the tops of the multiple support rods 6 maintain the same horizontal position. Since the interiors of the multiple sleeves 4 are interconnected through the connecting block 7, the air pressure on each support rod 6 is consistent, and the elastic supporting force provided is also the same, which enables the support member 2 to maintain a horizontal state and provide a consistent supporting force through each support rod 6, so that its support is stable.

[0044] The connecting block 7 is provided with a vent 8, and the vent 8 is provided with a valve 9, and the vent 8 is used to connect with an external gas source, and the valve 9 is used to control the opening and closing of the vent 8, so as to adjust the gas pressure in the chamber to provide different elastic supporting forces. In this way, when the carrier 2 descends to the same horizontal position, due to the different elastic supporting forces, the weight of the material in the material container 28 will also be different, so that it can adapt to different types of material containers 28.

[0045] See also Figure 3 In this embodiment: a positioning and clamping assembly is provided on the support frame 3, and the positioning and clamping assembly realizes effective positioning and clamping of the material container 28, thereby reducing the possibility of movement or tilting of the material container 28 during the material collection process. The positioning and clamping assembly includes two positioning and clamping units symmetrically distributed on both sides of the material container 28, which constitute the basic unit of the positioning and clamping assembly. The two positioning and clamping units cooperate with each other to complete the specific clamping action.

[0046] Each positioning and clamping unit includes a horizontally arranged mounting sleeve 10, each mounting sleeve 10 is fixedly connected to the support frame 3, and the mounting sleeve 10 is a hollow cylindrical structure with one end open, and the open end faces the material container 28. Each mounting sleeve 10 is plugged with a slide bar 11 slidably connected to the mounting sleeve 10 at one end close to the material container 28, and the mounting sleeve 10 provides a sliding track for the slide bar 11 and limits its movement direction so that it can only slide along the length direction of the mounting sleeve 10.

[0047] Each slide bar 11 is provided with a V-shaped clamping rod 12 at one end close to the material container 28. When the two slide bars 11 slide relative to or away from each other, the two V-shaped clamping rods 12 are respectively close to or away from the material container 28. The V-shaped clamping rod 12 directly clamps the material container 28, and due to the V-shaped design, it can not only clamp the material container 28, but also position the material container 28 in the middle of the V-shaped clamping rod 12 (due to the inclined surface design on both sides of the V-shaped clamping rod 12, when the material container 28 is not in the middle position, the V-shaped clamping rod 12 is pushed, and the material container 28 is pushed to move to the middle position of the material container 28 under the guidance of the inclined surface of the V-shaped clamping rod 12).

[0048] Each mounting sleeve 10 is provided with a spring 13, and the two ends of the spring 13 are respectively connected to the slide bar 11 and the end of the mounting sleeve 10 away from the material container 28. The two springs 13 push the two slide bars 11 to move relative to each other so that the two V-shaped clamping rods 12 approach the material container 28 and gradually clamp the material container 28. The spring 13 provides a thrust for the slide bar 11, so that it can slide toward the material container 28, so that the V-shaped clamping rod 12 can clamp the material container 28. In the clamping state, the spring 13 is in an elastic compression state, and its elastic compression force provides a clamping force for the V-shaped clamping rod 12 to clamp the material container 28. When the slide bar 11 is pulled toward one end of the material container 28, the spring 13 continues to compress, and the slide bar 11 drives the V-shaped clamping rod 12 away from the material container 28 so that the V-shaped clamping rod 12 releases the clamping of the material container 28.

[0049] A pull rope 14 is provided between the carrier 2 and the two slide bars 11, one end of the pull rope 14 is connected to the end of the slide bar 11 away from the V-shaped clamp rod 12, and the other end extends in a direction away from the V-shaped clamp rod 12, passes through the installation sleeve 10, and is connected to the carrier 2. When the carrier 2 moves downward, the two slide bars 11 can be pulled by the two pull ropes 14 to move in opposite directions, so that the two V-shaped clamp rods 12 are away from the material container 28 and gradually release the clamping of the material container 28. The pull rope 14 has a certain strength and flexibility, and can transmit the movement of the carrier 2 to the slide bar 11.

[0050] The design of the pull rope 14 enables the positioning clamping assembly to automatically adjust the clamping state of the clamping assembly according to the change of the material in the material container 28 on the carrier 2. When no material is contained, the positioning clamping assembly provides the positioning clamping function. After the material is contained, the overall weight of the material container 28 increases due to the increase in the material, and the material container 28 is more stable on the carrier 2, and is not easy to deviate or tip over, so the clamping assembly does not play a big role. At this time, the carrier 2 moves downward and pulls the two slide bars 11 to move in opposite directions through the pull rope 14 so that the two V-shaped clamping bars 12 release the clamping of the material container 28, which is also convenient for subsequent replacement of the material container 28 without causing interference.

[0051] When replacing the material container 28, the material container 28 containing the material can be first moved away from the positioning position of the positioning clamping assembly. However, in order to reduce the possibility of material overflowing from the discharge port 27 during the material replacement process, it is necessary to ensure that the material container 28 containing the material does not separate from the carrier 2. Then the empty material container 28 can be replaced to the positioning position of the positioning clamping assembly, and then the material container 28 containing the material can be completely moved out of the carrier 2. In this way, during the process of the elastic support structure returning to the original state and the discharge port 27 gradually opening, since the empty material container 28 has been replaced, the material can directly fall into the new material container 28 through the discharge port 27 without overflowing onto the carrier 2, and the positioning clamping assembly will not cause interference during this process, and the operation is also relatively convenient.

[0052] See also Figure 3 In this embodiment: in order to facilitate the installation of the seal 1 at the discharge port 27, the seal 1 is a hollow cylindrical structure with one end open. The seal 1 is sleeved on the outside of the discharge port 27 and can rotate relative to the discharge port 27. A flow port is provided at the other end of the seal 1 away from the other end. By rotating the seal 1, the flow port and the discharge port 27 overlap or staggered.

[0053] See also Figure 3 In this embodiment: the transmission assembly includes a rack 16 and a gear ring 15 sleeved on the outside of the seal 1, wherein one end of the rack 16 is hinged to the carrier 2, which means that the rack 16 can rotate at a certain angle relative to the carrier 2, and the other end extends vertically upward and meshes with the gear ring 15. The up and down movement of the rack 16 can drive the gear ring 15 to rotate and then drive the seal 1 to rotate.

[0054] An elastic member is disposed on the carrier 2 , through which the rack 16 and the gear ring 15 always maintain a meshing state.

[0055] When it is necessary to stop the material loading operation, the rack 16 is rotated to disengage the rack 16 from the gear ring 15, and then the seal 1 is manually rotated to close the discharge port 27. When the material is loaded again, the seal 1 is manually rotated again to open the discharge port 27. In addition to the transmission function, the gear ring 15 can also serve as an anti-slip structure to facilitate the rotation of the seal 1.

[0056] See also Figure 2 Specifically, the elastic member can be a spring 13, an elastic rubber pad, an elastic rope, an elastic sheet, or other elastic structures. In this embodiment, the elastic member is a first elastic sheet 17, which is located on the side of the rack 16 facing away from the gear ring 15, and one end of the first elastic sheet 17 is fixedly connected to the bearing member 2, and the other end is in contact with the rack 16.

[0057] See also Figure 4 and 5In other embodiments, the transmission assembly includes a first connecting rod 18 and a second connecting rod 19, one end of the first connecting rod 18 is hinged to the supporting member 2, the other end of the first connecting rod 18 extends upward and is movably connected to one end of the second connecting rod 19 in a detachable manner, and the other end of the second connecting rod 19 is fixedly connected to the sealing member 1.

[0058] When it is necessary to stop the material loading operation, the connection between the first connecting rod 18 and the second connecting rod 19 is first separated, and then the second connecting rod 19 is manually rotated to drive the seal 1 to rotate. During this process, the seal 1 closes the discharge port 27. When the material is loaded again, the second connecting rod 19 is manually rotated again to open the discharge port 27. In addition to the transmission function, the second connecting rod 19 can also be used as an operating handle for rotating the seal 1, so that it is more convenient to rotate the seal 1.

[0059] Specifically, a notch is provided at the top of the first connecting rod 18 near the sealing member 1, and a second elastic sheet 20 is provided outside the notch. The upper end of the second elastic sheet 20 is connected to the upper side wall of the notch, and the lower end extends downward along the notch, and the lower end of the second elastic sheet 20 also extends in a direction perpendicular to the first connecting rod 18 to form an arc-shaped portion. A clamping column 30 is provided at the end of the second connecting rod 19 away from the sealing member 1. When connecting, it is only necessary to clamp the clamping column 30 from the bottom of the second elastic sheet 20 into the notch. The second elastic sheet 20 is forced to open in a direction away from the notch so that the clamping column 30 can smoothly enter the notch. After the clamping column 30 completely enters the notch, the second elastic sheet 20 elastically recovers to limit the clamping column 30. Similarly, when disassembling, it is only necessary to pull the first connecting rod 18 and the second connecting rod 19 apart, and the clamping column 30 is separated from the slot under the action of the second elastic sheet 20.

[0060] It should be noted that when the first connecting rod 18 moves up and down, the clamping column 30 will respectively abut against the upper and lower ends of the notch and will not easily fall out of the notch, thereby enabling the first connecting rod 18 and the second connecting rod 19 to transmit normally.

[0061] The second of the present invention: See also Figure 1 , a conveyor, comprising the above-mentioned quantitative feeding mechanism; A first conveying mechanism 21, which is disposed above the carrier 2 and can move up and down with the carrier 2. The first conveying mechanism 21 is used to transport the material container 28. A first transmission member 22 is disposed on the first conveying mechanism 21; The second conveying mechanism 23 is provided with a second transmission member 24. When the material container 28 is filled with a given material, the first conveying mechanism 21 is lowered to a position at the same level as the second conveying mechanism 23, and the first transmission member 22 and the second transmission member 24 act to enable the second conveying mechanism 23 to drive the first conveying mechanism 21 to operate.

[0062] In the initial state, the first conveying mechanism 21 is located at a higher position. The second conveying mechanism 23 is located at a lower position, waiting to receive the material container 28 transmitted from the first conveying mechanism 21. When the material container 28 is placed on the first conveying mechanism 21 and is gradually filled with materials, the carrier 2 begins to descend until the material container 28 is added with a preset weight of materials, and the first conveying mechanism 21 and the second conveying mechanism 23 are at the same horizontal position. At this time, the first transmission member 22 and the second transmission member 24 act, and through the interaction of the transmission members, the second conveying mechanism 23 starts to drive the first conveying mechanism 21 to operate. The first conveying mechanism 21 transfers the container filled with materials to the second conveying mechanism 23, and the second conveying mechanism 23 continues to transfer the container to the next process or position.

[0063] The second conveying mechanism 23 can be used to convey the loaded materials, thus saving the labor cost of manual transportation. The first conveying mechanism 21 and the second conveying mechanism 23 are linked together through the first transmission member 22 and the second transmission member 24. When a preset weight of material is added to the material container 28 (the first conveying mechanism 21 and the second conveying mechanism 23 are at the same horizontal position), the first transmission assembly and the second transmission assembly will take effect, so that the second conveying mechanism 23 drives the first conveying mechanism 21 to operate, and directly conveys the material container 28 loaded with the given material to the next process, with a high degree of automation.

[0064] Specifically, the first conveying mechanism 21 and the second conveying mechanism 23 are both chain roller conveying mechanisms, the first transmission member 22 is a first sprocket, the first transmission member 22 is installed on the rotating shaft of the roller of the first conveying mechanism 21 close to the second conveying mechanism 23, the second transmission member 24 is located below the first transmission member 22, the second transmission member 24 includes two second sprockets respectively installed on the support frame 3 and the rotating shaft of the roller of the second conveying mechanism 23 close to the first conveying mechanism 21, and the two second sprockets are driven by the first chain. When the first conveying mechanism 21 moves downward, it will drive the first sprocket to move downward synchronously until the first sprocket is meshed with the first chain. Since the second conveying mechanism 23 is in an operating state, the first chain is in an operating state. When the first sprocket is meshed with the first chain, it can drive the first sprocket to rotate, thereby realizing linkage.

[0065] Furthermore, one of the second sprockets is fixedly connected to the rotating shaft of the roller of the second conveying mechanism 23 close to the first conveying mechanism 21, and the first screw rod is rotatably connected to the support frame 3, the first screw rod is arranged along the vertical direction, and the first slider is sleeved on the first screw rod, the first slider is connected to the first screw rod by threaded matching, the first slider is slidably connected to the support frame 3 along the length direction of the first screw rod, and the other second sprocket is installed on the first slider. By rotating the first screw rod, the first slider can slide along the length direction of the first screw rod, thereby adjusting the position of the first chain, and then facilitating the adjustment of the position of the first chain when meshing with the first sprocket, so that the installation and commissioning of the device is smoother.

[0066] In addition, the first transmission member 22 and the second transmission member 24 can be gears, one of which is installed on the rotating shaft of the roller of the first conveying mechanism 21 close to the second conveying mechanism 23, and the other gear is installed on the rotating shaft of the roller of the second conveying mechanism 23 close to the first conveying mechanism 21.

[0067] See also Figure 1 In this embodiment: the conveyor further includes a third conveying mechanism 29, on which a third transmission member 25 is provided, and on which a fourth transmission member 26 is provided. When a given material is contained in the material container 28, the first conveying mechanism 21, the second conveying mechanism 23 and the third conveying mechanism 29 are all kept at the same horizontal position, and the third transmission member 25 and the fourth transmission member 26 act to enable the first conveying mechanism 21 to drive the third conveying mechanism 29 to operate.

[0068] The empty material container 28 can be transported through the third conveying mechanism 29, saving the labor cost of manual transportation, and the first conveying mechanism 21, the second conveying mechanism 23 and the third conveying mechanism 29 are linked together through the third transmission member 25 and the fourth transmission member 26. When a preset weight of material is added to the material container 28 (the first conveying mechanism 21, the second conveying mechanism 23 and the third conveying mechanism 29 are at the same horizontal position), the second conveying mechanism 23 drives the first conveying mechanism 21 to operate and transport the material container 28 filled with the given material to the next process. At the same time, under the action of the third transmission member 25 and the fourth transmission member 26, the first conveying mechanism 21 drives the third conveying mechanism 29 to operate and transport the empty material container 28 to the first conveying mechanism 21, thereby reducing the process of manually replacing the empty material container 28, saving labor, and further improving the degree of automation.

[0069] Specifically, the third conveying mechanism 29 is also a chain roller conveying mechanism, the fourth transmission member 26 is a third sprocket, the fourth transmission member 26 is installed on the rotating shaft of the roller of the first conveying mechanism 21 close to the third conveying mechanism 29, the third transmission member 25 is located below the first transmission member 22, and the third transmission member 25 includes two fourth sprockets respectively installed on the supporting frame 3 and the rotating shaft of the roller of the third conveying mechanism 29 close to the first conveying mechanism 21, and the two fourth sprockets are driven by the second chain. When the first conveying mechanism 21 moves downward, it will drive the third sprocket to move downward synchronously until the third sprocket is meshed with the second chain. Since the first conveying mechanism 21 is in an operating state under the linkage of the second conveying mechanism, the second chain is in an operating state. When the third sprocket is meshed with the second chain, it can drive the fourth sprocket to rotate, thereby driving the third conveying mechanism 29 to operate and realize linkage.

[0070] Furthermore, one of the fourth sprockets is fixedly connected to the rotating shaft of the roller of the third conveying mechanism 29 close to the first conveying mechanism 21, and the support frame 3 is rotatably connected with a second screw rod, which is arranged along the vertical direction, and the second screw rod is sleeved with a second slider, which is connected to the second screw rod by threaded matching, and the second slider is slidably connected to the support frame 3 along the length direction of the second screw rod, and another fourth sprocket is installed on the second slider. By rotating the second screw rod, the second slider can slide along the length direction of the second screw rod, thereby adjusting the position of the second chain, and then facilitating the adjustment of the position of the second chain when it is meshed with the third sprocket, so that the installation and commissioning of the device is smoother.
