Description

Technical Field

[0001] The utility model relates to the technical field of powder material feeding, in particular to a powder material blanking device and a subcontracting production line. Background Art

[0002] In existing powder subcontracting production lines, large packages of compound additives are typically hoisted and dropped directly into a feed hopper through an opening at the bottom of the bag. The gap between the bag and the hopper creates additive dust during the drop process. This dust not only pollutes the environment but also poses a health risk to workers. Lead-acid battery compound additives, due to their powdery nature, are also plagued by this problem.

[0003] Therefore, the gap between the bag and the feed bin causes dust to easily spread during the blanking process, affecting the on-site environment. The existing blanking method lacks effective sealing measures and cannot effectively prevent the potential harm of additive dust to workers' health. Utility Model Content

[0016] One or more technical solutions provided in the embodiments of the present invention at least have the following technical effects or advantages:

[0017] This powder feeding and blanking device includes a feeding bin, a sealing sleeve and a driving mechanism, and is used for sealing the material bag of the bale to prevent dust diffusion. In this device, a feeding cylinder is provided on the feeding bin, and the sealing sleeve is composed of a sleeve ring and a pressing ring. The sleeve ring is sleeved on the outer side of the feeding cylinder, the pressing ring is located at the upper end of the sleeve ring, and the inner diameter of the pressing ring is smaller than the outer diameter of the feeding cylinder.

[0026] It should be noted that the following detailed description is illustrative and intended to further illustrate the present invention. Unless otherwise indicated, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which the present invention pertains. Composite additives are powdered materials that are produced in large quantities and packaged for storage. When purchased by a customer, they are subpackaged according to their specifications, with the large package (i.e., the material pack) being divided into smaller packages that meet the customer's needs.

[0027] As described in the background art, during subpackaging, large bags of additives need to be hoisted so that the additives fall onto the subpackaging production line. The bag has a bag at the bottom. During on-site operation, the bag is directly placed into the feed bin, and the powder falls into the bin under the action of gravity. Due to the gap between the bag and the feed bin, and the additive being in powder form, dust is easily generated during the dropping of the material, affecting the on-site environment. In addition, lead-acid battery composite additives are toxic to a certain extent, affecting the health of workers. In order to solve the above technical problems, the utility model proposes a powder dropping device for closing the bag of the bag.

[0028] like Figure 1、 Figure 2 As shown, the powder material feeding device includes: a feeding bin 1, a sealing sleeve 4 and a driving mechanism 5; Figure 3 As shown, a feed barrel 11 is provided on the feed bin 1. The sealing sleeve 4 includes a collar 41 and a pressure ring 42. The collar 41 is sleeved on the outside of the feed barrel 11. The pressure ring 42 is located at the upper end of the collar 41, and the inner diameter of the pressure ring 42 is smaller than the outer diameter of the feed barrel 11. The driving mechanism 5 includes a fixed end and a movable end. The fixed end is fixed to the feed bin 1, and the movable end is connected to the sealing sleeve 4 and can drive the pressure ring 42 of the sealing sleeve 4 to press the material bag 61 onto the feed barrel 11.

[0029] When the powder material dropping device is in use, Figure 4 As shown, the material bag 6 is hoisted to the upper side of the blanking device, and the opening at the bottom end of the material belt is bent outward and plugged into the gap between the sealing sleeve 4 and the feeding barrel 11. The driving structure drives the sealing sleeve 4 to move downward to seal the opening of the material belt, so that a sealed channel is formed between the material bag 6 and the feeding bin 1, preventing the spread of dust during the blanking process, ensuring the cleanliness of the site, and ensuring the health of the staff.

[0030] The diameter of the feed barrel 11 is smaller than that of the feed bin 1, and the fixed end of the drive mechanism 5 is mounted on the outer wall of the feed barrel 11. This size difference helps to achieve a better seal and provides a stable support surface for mounting the drive mechanism 5. By fixing the drive mechanism 5 on the outer wall of the feed barrel 11, the movement of the sealing sleeve 4 can be better controlled, thereby achieving a more efficient sealing effect.

[0031] The collar 41 is cylindrical, and the pressure ring 42 is plate-like. A predetermined gap exists between the inner wall of the cylindrical structure and the outer wall of the feed barrel 11. This structural design facilitates the insertion of the lower end of the bag 61 between the sealing sleeve 4 and the feed barrel 11, while also ensuring that when the pressure ring 42 is pressed downward, the sealing sleeve 4 firmly presses against the opening of the bag 61, thereby forming a seal. This gap design also makes the sealing operation more convenient and efficient.

[0032] The collar 41 of the sealing sleeve 4 is provided with an access opening 43, which is arranged radially along the collar 41 and extends through the thickness of the collar 41. This design facilitates the operator to insert the lower end of the bag 61 between the sealing sleeve 4 and the feed barrel 11 from the side. The presence of the access opening 43 simplifies the operation process and greatly improves work efficiency.

[0033] There are four operation ports 43 provided, and the four operation ports 43 are respectively arranged on the front side and the rear side of the sealing sleeve 4, two on the front side and two on the rear side. The design of multiple operation ports 43 enables the operator to use both hands for operation at different positions, improving the flexibility and convenience of the sealing process, reducing the operation time and labor intensity, and enhancing the overall production efficiency.

[0034] The driving mechanism 5 can adopt a cylinder. The cylinder includes a cylinder body and a piston rod. The cylinder body is fixed at the fixed end on the outer wall of the feeding cylinder 11, and the piston rod is installed at the movable end at the bottom end of the sealing sleeve 4. The advantage of using a cylinder as the driving mechanism 5 is that the cylinder can provide stable and controllable pressure, enabling the sealing sleeve 4 to reliably press the opening of the material bag 61 against the feeding cylinder 11 to ensure the sealing effect. In addition, the operation of the cylinder is simple and easy to maintain.

[0035] The powder feeding device further includes a support frame 2 and a pushing frame 3. The feeding bin 1 is located at the bottom side of the support frame 2. There are two pushing frames 3, and the two pushing frames 3 are symmetrically arranged on the left and right sides of the top of the support frame 2 along the material bag 6, and the pushing frame 3 is rotationally connected to the support frame 2. The rotational function of the pushing frame 3 can further squeeze the two sides of the material bag, push the powder on the two sides of the material bag towards the middle, promote the powder to completely fall into the feeding bin 1, and improve the thoroughness and efficiency of the feeding.

[0036] As Figure 5 shown, the pushing frame 3 includes an outer frame 31 and an inner frame 32. The outer frame 31 is in a U - shaped form, and the inner frame 32 is in an E - shaped form. The inner frame 32 is located inside the outer frame 31. Rotating shafts 33 are provided at both ends of the outer frame 31, and the pushing frame 3 is rotationally installed on the support frame 2 through the rotating shafts 33. The pushing frame 3 can be driven by a hydraulic cylinder. The lower end of the hydraulic cylinder is rotationally installed on the cross braces on both sides of the support frame 2, and the upper end of the hydraulic cylinder is rotationally installed on the bottom side of the inner frame 32. Under the drive of the hydraulic cylinder, the outer end of the pushing frame 3 can rotate towards the middle, thereby pushing the powder in the material bag to fall more fully and improving the feeding efficiency.

[0037] There is a set angle between the inner frame 32 and the outer frame 31. The inner side of the inner frame 32 is installed on the outer frame 31, and the outer side of the inner frame 32 is higher than the outer frame 31. This angle design can make the powder fall more thoroughly from the middle, avoid blockage and material accumulation phenomena, avoid residues, and further improve the feeding efficiency.

[0038] Based on the above powder feeding device, an embodiment of the present invention further provides a sub - packaging production line. This production line uses the powder feeding device to ensure smooth powder feeding and tight sealing during the sub - packaging process, avoid dust diffusion, protect the environment and the health of operators, and at the same time improve the efficiency and accuracy of sub - packaging production.

[0039] Although the above describes the specific implementation methods of the present invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or variations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
