Description

Technical Field

[0001] This utility model relates to the field of bucketless scales, and more specifically, to a gravity bucketless scale. Background Technology

[0002] Gravity hopperless scales are automatic weighing instruments that use gravity and sensors to directly measure the mass of materials. They do not have traditional weighing hoppers. Materials are usually continuously passed through the weighing mechanism to complete dynamic measurement. The scale receives the gravity of the material through a load-bearing structure, and the gravity signal is converted into an electrical signal by a weight sensor. After processing by the instrument, the mass data of the material is displayed or output. It is commonly used in continuous measurement scenarios of bulk materials.

[0003] Existing gravity hopperless scales still have certain shortcomings in use. For example, most existing gravity hopperless scales only have basic weighing functions and need to be used with external equipment to achieve quantitative material feeding. In the material bagging process, manual support is required to align the opening of the material bag with the discharge port, resulting in poor quantitative accuracy, low bagging efficiency, and high manual labor intensity.

A material drop groove is provided on the surface of the arc-shaped baffle plate, and a driving component is disposed inside the mounting box at a position relative to the arc-shaped baffle plate.

[0010] Furthermore, the driving component includes a stepper motor fixedly installed on the inner wall of the mounting box. The telescopic end of the stepper motor is hinged to a connecting plate.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0031] Example 1:

[0032] Please see Figure 1-3 A gravity-fed bucketless scale includes a main body 1, a base plate 2 fixedly installed at the bottom of the main body 1, a control box 3 fixedly installed on the side of the main body 1, a feeding box 4 and an installation box 5 fixedly installed at the top of the main body 1, a guide plate 6 installed inside the feeding box 4, a discharge cylinder 7 fixedly installed at the bottom of the feeding box 4 relative to the guide plate 6, a weighing control mechanism 8 provided at the connection between the feeding box 4 and the installation box 5, and a clamping mechanism 9 provided on the surface of the discharge cylinder 7. In use, the material bag is first fixed to the bottom opening of the discharge cylinder 7 by the clamping mechanism 9, and then the material is fed into the inside of the guide plate 6 through the feeding box 4. The material is weighed by the weighing control mechanism 8 and then discharged through the discharge cylinder 7 into the material bag for filling.

[0033] Furthermore, the weighing control mechanism 8 includes an arc-shaped baffle plate 81 located at the bottom of the inner cavity of the guide plate 6, and a weighing sensor 82 installed at the bottom of the arc-shaped baffle plate 81. A material drop groove 83 is provided on the surface of the arc-shaped baffle plate 81, and a driving component 84 is provided inside the mounting box 5 at a position relative to the arc-shaped baffle plate 81. When the material is weighed, the arc-shaped baffle plate 81 closes the opening at the bottom of the guide plate 6. Under the action of the weighing sensor 82, the material inside can be weighed. After the material is weighed, the driving component 84 drives the arc-shaped baffle plate 81 to rotate to the position where the material drop groove 83 is located at the bottom opening of the guide plate 6. The material falls into the material drop cylinder 7 through the material drop groove 83, and is finally loaded through the material bag clamped on the clamping mechanism 9.

[0034] The driving component 84 includes a stepper motor 841 fixedly installed on the inner wall of the mounting box 5. The telescopic end of the stepper motor 841 is hinged to a connecting plate 842. A first linkage rod 843 is fixedly sleeved on one side of the connecting plate 842. Two first linkage plates 844 are symmetrically fixedly installed on the surface of the first linkage rod 843. The two first linkage plates 844 are respectively connected to both sides of the arc-shaped baffle plate 81. When the arc-shaped baffle plate 81 is rotated, the stepper motor 841 is turned on. With the connection of the connecting plate 842, the first linkage rod 843 can rotate. With the connection of the first linkage plates 844, the arc-shaped baffle plate 81 can rotate.

[0035] It should also be noted that a mounting base 845 is fixedly sleeved on the surface of the feed box 4 relative to the position of the first linkage rod 843, and the mounting base 845 and the first linkage rod 843 are rotatably connected; by setting the mounting base 845, the stability of the first linkage rod 843 during rotation can be increased.

[0036] Furthermore, the clamping mechanism 9 includes four clamping blocks 91 disposed on the side of the discharge cylinder 7, and two bidirectional cylinders 92 symmetrically mounted on the surface of the discharge cylinder 7. A linkage component 93 is provided at the connection between the clamping blocks 91 and the bidirectional cylinders 92. By setting the clamping blocks 91, the bidirectional cylinders 92 and the linkage component 93, the material bag can be clamped.

[0037] The linkage component 93 includes a mounting plate 931 fixedly installed on the surface of the discharge cylinder 7. Both sides of the mounting plate 931 are rotatably connected to linkage components 932. The inner sides of the two linkage components 932 are respectively hinged to the two ends of the bidirectional cylinder 92. The corners of the two linkage components 932 are fixedly sleeved with second linkage rods 933. The surfaces of the two second linkage rods 933 are fixedly sleeved with two second linkage plates 934 relative to the positions of the four clamping blocks 91. The four second linkage plates 934 and the four clamping blocks 91 are fixedly connected.

[0038] Specifically, when clamping the material bag, the bidirectional cylinder 92 is opened, and the two ends of the bidirectional cylinder 92 extend outward, thereby causing one end of the two linkages 932 to move outward. Under the connection of the second linkage rod 933 and the second linkage plate 934, the clamping block 91 can be moved outward. Then, the material bag is placed on the outside of the bottom end of the discharge cylinder 7, and the two sides of the material bag are respectively located inside the two clamping blocks 91. Then, the bidirectional cylinder 92 retracts, and the linkages 932 move in the opposite direction. Under the connection of the second linkage rod 933 and the second linkage plate 934, the two adjacent clamping blocks 91 can move towards each other to clamp the material bag.

[0039] It should also be noted that a baffle 10 is fixedly installed on the side of the main body 1. By setting the baffle 10, the material bag can be limited. A smoke exhaust pipe 11 is fixedly installed on the side of the feed box 4. The bottom of the smoke exhaust pipe 11 passes through the inside of the guide plate 6. By setting the smoke exhaust pipe 11, it can play the role of exhausting smoke and dust when the material is put into the feed box 4.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
