[0025] In order to solve the problem in the prior art that materials splash out of the barrel during the metering process and the problem that the service life of the weighing sensor is affected by rotation, the utility model provides a material metering and weighing device.

[0026] Figures 1 to 4 The material metering and weighing device shown in the figure includes a frame 10, a turntable 20, a material receiving assembly 30, a weighing assembly 40, and a lifting assembly 50. The turntable 20 is rotatably connected to the frame 10, and a bag-loading position, a feeding position, and a discharge position are arranged on the circumference of the turntable 20; the material receiving assembly 30 is connected to the turntable 20, and switches between the bag-loading position, the feeding position, and the discharge position under the drive of the turntable 20, the material receiving assembly 30 can be raised and lowered relative to the turntable 20, and a material receiving port 33 is arranged at the top of the material receiving assembly 30; the weighing assembly 40 is connected to the material receiving assembly 30; the lifting assembly 50 is connected to the turntable 20 and to the weighing assembly 40, the lifting assembly 50 drives the material receiving assembly 30 to rise and fall through the weighing assembly 40, and the weighing assembly 40 measures and weighs the material receiving assembly 30 when the material receiving assembly 30 is raised and lowered.

[0027] In this embodiment, a lifting assembly 50 is provided, and the lifting assembly 50 cooperates with the weighing assembly 40, and the weighing assembly 40 cooperates with the material receiving assembly 30, so that the lifting assembly 50 can drive the material receiving assembly 30 to lift together through the weighing assembly 40, and a material receiving port is provided at the top of the material receiving assembly 30. On the one hand, such a setting makes it unnecessary for the weighing assembly 40 to be arranged at the top of the material receiving assembly 30, so that the cantilever of the weighing assembly 40 from the bottom of the material receiving assembly 30 is smaller, and the torque exerted on the weighing assembly 40 is reduced when the whole rotates, thereby extending the life of the weighing sensor inside the weighing assembly 40; on the other hand, the way of setting the material receiving port at the top can optimize the material receiving method and prevent the material from splashing during the weighing process, that is, when the turntable 20 drives the material receiving assembly 30 to rotate to the feeding position, the lifting assembly 50 can drive the weighing assembly 40 and the material receiving assembly 30 to lift to a suitable position to receive and weigh the material, thereby avoiding the splashing of the material during the falling process caused by the traditional side opening method, reducing the dust and fragments generated during the weighing process, and improving the product quality.

[0028] like Figure 2 As shown, the weighing assembly 40 of this embodiment is located on the side of the material receiving assembly 30 facing the turntable 20, and along the radial direction of the turntable 20, the lifting assembly 50, the weighing assembly 40 and the material receiving assembly 30 are arranged in sequence. Specifically, this embodiment does not adopt the traditional method of setting the weighing assembly 40 at the top of the material receiving assembly 30, but sets the weighing assembly 40 on the side of the material receiving assembly 30 closer to the center of the turntable 20, so that the distance from the weighing assembly 40 to the bottom of the material receiving assembly 30 is smaller, thereby reducing the torque on the weighing assembly 40, thereby improving the reliability and service life of the weighing assembly 40. It should be noted that the rotation center refers to the rotation center of the turntable 20, that is, the rotation center where the turntable 20 drives the lifting assembly 50, the weighing assembly 40 and the material receiving assembly 30 to rotate together.

[0029] like Figure 3 As shown, in this embodiment, the lifting assembly 50 includes a lifting plate 51 that can be lifted and moved, the weighing assembly 40 is connected to the lifting plate 51, the material receiving assembly 30 includes a material receiving barrel 31, the weighing assembly 40 is connected to the material receiving barrel 31, and the lifting plate 51 drives the material receiving barrel 31 to rise and fall through the weighing assembly 40. The lifting plate 51 of this embodiment is placed vertically, so that the surface of the lifting plate 51 with a larger side area can be connected to the weighing assembly 40, thereby ensuring the reliability of the connection. At the same time, the lifting and lowering of the material receiving barrel 31 is achieved by the weighing assembly 40 transmitting the driving force of the lifting assembly 50, and the setting mode also enables the weighing assembly 40 to accurately weigh the material barrel 31 and the material inside.

[0030] In this embodiment, the lifting assembly 50 further includes a lifting frame 52, a lifting drive 53, and a lifting guide mechanism 54. The lifting frame 52 is connected to the turntable 20 and rotates synchronously with the turntable 20. The lifting drive 53 is connected to the lifting frame 52, and the output end of the lifting drive 53 is connected to the lifting plate 51, and drives the lifting plate 51 to move up and down. The lifting guide mechanism 54 is arranged between the lifting frame 52 and the lifting plate 51, and the lifting plate 51 moves up and down along the guide direction of the lifting guide mechanism 54. Specifically, the lifting assembly 50 is connected to the turntable 20 through the lifting frame 52, so that when the turntable 20 rotates, the lifting frame 52 can drive the lifting assembly 50 as a whole to rotate synchronously with the turntable 20. The lifting frame 52 of this embodiment adopts the form of a beam structure, which includes two upper and lower spaced cross beams and a longitudinal beam arranged longitudinally. The longitudinal beam can be a larger beam or multiple beams. The upper and lower ends of the longitudinal beam are respectively connected to two cross beams, thereby forming the lifting frame 52. The bottom end of the longitudinal beam and the lower cross beam can be connected to the turntable 20 through bolts and other components. The lifting drive 53 can be a motor or a cylinder. In this embodiment, a cylinder is used as the lifting drive 53, and the lifting plate 51 is connected to the cylinder rod of the cylinder. The lifting guide mechanism 54 can be a slide block, and the slide is set in an up-and-down extension manner. In this way, a slide block protruding from the lifting frame 52 is set on the side of the lifting frame 52 facing the lifting plate 51, and a slide in the height direction is set on the lifting plate 51, so that the slide block can move in the slide. After the lifting drive 53 is started, the lifting drive 53 acts on the lifting plate 51. Due to the existence of the slide, the lifting plate 51 can only move in the height direction, thereby driving the weighing assembly 40 and the material receiving barrel 31 connected to the lifting plate 51 to move in the height direction. Of course, the lifting guide mechanism 54 can also be set in other ways such as a linear guide column, a linear guide rail, a parallel connecting rod structure, etc., which can play a guiding role in the lifting and lowering of the lifting plate 51.

[0031] In this embodiment, if Figure 3 As shown, the material receiving assembly 30 further includes a clamping mechanism 32, which is located outside the material receiving barrel 31 and is used to clamp the material bag sleeved on the material receiving barrel 31. The clamping mechanism 32 can be in the form of a clamping claw or the like, so that in the bag loading position, the clamping mechanism 32 can clamp the empty material bag to the material receiving barrel 31 to prepare for material receiving; in the material unloading position, the clamping mechanism 32 releases the material bag, and the material bag is separated from the material receiving barrel 31, so that the material bag is sleeved outside the material receiving assembly 30, reducing the probability of the material bag being punctured by a heavy and sharp material.

[0032] In this embodiment, the material metering and weighing device further comprises a feeding device 60, the feeding device 60 has a discharge port 61, the material receiving assembly 30 has a material receiving port 33, the material receiving assembly 30 has an initial state and a material receiving state, when the material receiving assembly 30 is in the initial state, an upper and lower gap is formed between the material receiving port 33 and the discharge port 61; when the material receiving assembly 30 is in the material receiving state, the material receiving assembly 30 rises, and the top height of the material receiving port 33 is not lower than the bottom height of the discharge port 61. Specifically, the material receiving port 33 rotates with the turntable 20 to the bottom of the discharge port 61 and reaches the feeding position, at which time the material receiving port 33 and the discharge port 61 are located in the same axial direction and a gap is formed in the height direction, and then the lifting assembly 50 acts to make the material receiving port 33 rise until the material receiving port 33 abuts against the discharge port 61 or partially overlaps in the height direction, so that splashing of the material in the process of falling from the discharge port 61 to the receiving barrel 31 can be avoided.

[0033] In this embodiment, the feeding device 60 includes a feeding trough body 62, the bottom end of which has a protruding section extending downward, and the protruding section has a discharge port 61. When the receiving assembly 30 is in a receiving state, at least a portion of the protruding section is located in the receiving assembly 30. In other words, the cross-sectional size of the receiving port 33 is larger than the cross-sectional size of the discharge port 61. When the receiving barrel 31 rises to the height of the discharge port 61 and continues to rise, the receiving port 33 can be sleeved to the outside of the discharge port 61. In this way, when weighing, the receiving assembly 30 rises as a whole, such as Figure 4 As shown, the discharge port 61 is partially embedded in the receiving port 33 to ensure that the material will not splash outside the receiving barrel 31 during the entire weighing process, thereby ensuring the cleanliness of the on-site environment and avoiding material waste.

[0034] In this embodiment, the top of the receiving barrel 31 of the receiving assembly 30 has a conical structure, the top of the conical structure is the large diameter end, the bottom of the conical structure is the small diameter end, and the large diameter end has a receiving port 33. In this way, on the one hand, when the receiving assembly 30 rises, the inclined surface of the conical structure can play a guiding role. As long as the discharge port 61 and the receiving port 33 are roughly aligned, it can automatically correct its position under the action of the inclined surface of the conical structure to achieve a nested matching form. On the other hand, it is not necessary to set the receiving barrel 31 as a whole in a form with a cross section larger than the discharge port 61. It is only necessary to set the cross section of the large diameter end to be larger than the cross section of the discharge port 61, so that the receiving port 33 can be sleeved to the outside of the extended section. Preferably, the cross-section of the large diameter end of the conical structure can be set to be larger than the cross-section of the discharge port 61 and the cross-section of the small diameter end can be larger than the cross-section of the discharge port 61. By setting the lifting height of the receiving barrel 31, the end of the discharge port 61 can be abutted against the inclined surface of the conical structure of the receiving barrel 31. In this way, not only the splashing of the material in the falling direction is avoided, but also the splashing of the material from the surrounding of the receiving barrel 31 to the outside after falling into the receiving barrel 31 can be avoided.

[0035] In this embodiment, the feeding device 60 includes a feeding trough body 62, a feeding frame 63, and a dust removal mechanism 64. The feeding trough body 62 has an inner cavity for conveying materials, which extends laterally; the feeding frame 63 serves as a basic component, and the feeding trough body 62 is connected to the feeding frame 63 and supported on the feeding frame 63; the dust removal mechanism 64 is connected to the feeding trough body 62 and communicates with the inner cavity of the feeding trough body 62. The dust removal mechanism 64 is located above the discharge port 61, so that negative pressure sucks dust out of the discharge port 61.

[0036] In the present embodiment, the material metering and weighing device further comprises a turntable drive 70, which is connected to the frame 10 and is drivingly connected to the turntable 20. The turntable drive 70 drives the turntable 20 to drive the material receiving assembly 30, the weighing assembly 40 and the lifting assembly 50 to rotate synchronously. Specifically, the turntable drive 70 can drive the turntable 20 to rotate, thereby driving the material receiving assembly 30 to switch between the bag loading position, the feeding position and the unloading position, thereby completing the bag loading, feeding and unloading work. The rotation direction of the turntable 20 of the present embodiment is not limited, and the turntable drive 70 can be set to drive the turntable 20 to rotate counterclockwise. The workstation arrangement sequence is as follows: Figure 1 As shown, a turntable driving member 70 may also be provided to drive the turntable 20 to rotate clockwise, and the arrangement sequence of the workstations is changed accordingly.

[0037] In this embodiment, at least three receiving components 30 are evenly distributed around the turntable 20, and each receiving component 30 is equipped with a weighing component 40 and a lifting component 50 so that it can complete weighing respectively. The angle of each rotation of the turntable 20 is equal to the angle between two adjacent receiving components 30. At least three receiving components 30 correspond to the bag loading position, the feeding position, and the unloading position respectively, and a feeding device 60 is arranged above the feeding position. Among them, multiple feeding positions can be set, so that multiple feeding positions can realize efficient measurement of different materials or materials of different specifications according to the target weight segment, thereby realizing the parallel bag loading, weighing and unloading of multiple stations, improving the automation and efficiency of production, and the measurement of each feeding position in sequence reduces the number of times and height of the material falling during the measurement and loading process, minimizes the generation of broken materials and dust impurities, and improves the product quality.

[0038] The use process of the material weighing device of this embodiment is as follows: in the initial state, the 1# empty material bag is automatically put on the material receiving tube 31 of the material receiving assembly 30 at the upper bag position through the automatic bag feeding machine, and the clamping mechanism 32 automatically clamps the material bag on the material receiving tube 31; after the action process of the upper bag position is completed, the turntable driving member 70 drives the turntable 20 to rotate a fixed angle, and the 2# empty material bag enters the upper bag position to repeat the bagging process; the 1# empty material bag enters the feeding position 1 and executes the weighing process: the lifting driving member 53 of the lifting assembly 50 above the turntable 20 drives the material receiving assembly 30 to rise, so that the material receiving port 33 and the material discharge port 61 are nested and overlapped, eliminating the upper and lower directions. The gap between the receiving assembly 30 is recorded and then the tare weight is removed. The feeding device 60 above starts to add material. After reaching the weighing range set by the control system for the feeding position, the metering is stopped. The lifting assembly 50 drives the receiving assembly 30 to descend, leaving a gap in the up and down directions. In this process, the dust hood of the dust removal mechanism 64 participates in the collection of unloading dust. After the action processes of the 1# bag and the 2# bag at the current stations are completed, the turntable driving member 70 drives the turntable 20 to rotate a fixed angle, and the 3# empty bag enters the bag loading position to repeat the bag loading process, the 2# empty bag enters the feeding position 1 to execute the weighing process, and the 1# bag enters the feeding position 2 to execute the weighing process. After the action process of each current station is completed, the turntable drive 70 drives the turntable 20 to rotate a fixed angle, 4# empty bag enters the bag loading position to repeat the bag loading process, 3# empty bag enters feeding position 1, 2# bag enters feeding position 2; 1# bag enters the unloading position to execute the unloading process: the material basket below the receiving barrel 31 rises so that the material basket docks with the bottom of the receiving assembly 30, the clamping mechanism 32 automatically releases the material bag, the material basket below descends, the material bag detaches from the receiving assembly 30 and enters the material basket, and the material bag leaves the material metering and weighing device with the material basket. After the action process of each current station is completed, the turntable drive 70 drives the turntable 20 to rotate a fixed angle, 5# empty bag enters the bag loading position to repeat process 1, 4# empty bag enters feeding position 1, 3# bag enters feeding position 2; 2# bag enters the unloading position to execute the unloading process, and this cycle repeats.
