Description

Technical Field

[0001] The utility model belongs to the technical field of feed packaging, and particularly relates to a dust leakage prevention device in a bag clamping mechanism. Background Art

[0002] During the feed processing, dust leakage in the bag clamping mechanism of the powder packaging scale is a common pain point problem. When the packaging bag leaves the bag clamping mechanism, dust will continue to fall from the discharge port of the bag clamping mechanism, which not only affects the on-site environment but also poses a hidden danger to the health of workers. Therefore, people have tried to improve the above deficiencies.

[0003] Solution 1: Add a partition inside the bag clamping mechanism and increase air duct suction dust removal; Solution 2: Do suction dust removal by adding an external suction port; Solution 3: Combine the technical solutions of Solution 1 and Solution 2. Although the above technical solutions have achieved some effects, these technical solutions still have deficiencies. For Solution 1, this technical solution can reduce the dust leakage phenomenon, but if the wind force is too large, a large amount of finished materials will be sucked away, and vice versa, the effect is not good, and there is still dust scattering. For Solution 2, this technical solution is only effective for dust with relatively light quality, and it has no effect on slightly heavier powder materials, and the external suction device occupies space. For Solution 3, only the effect is improved compared with using Solution 1 and Solution 2 alone, but the problem of dust leakage still cannot be completely solved.

[0004] Traditional technical solutions need to add a suction device, and the air duct is connected to the wind network system. The structure occupies a large space, has high energy consumption and high cost, and cannot completely solve the problem of dust leakage. Obviously, there is still room for further improvement. Therefore, it is of great significance to study a technical solution for preventing dust leakage in the bag clamping mechanism with low energy consumption and low cost. Content of the Utility Model

[0005] In order to solve the technical problem of dust leakage in the bag clamping mechanism during the feed processing in the background art, the purpose of the utility model is to provide a dust leakage prevention device in the bag clamping mechanism, which can solve the above problems.

[0006] The technical solution for achieving the purpose of the utility model is: a dust leakage prevention device in a bag clamping mechanism, including a blanking barrel body, a partition board, and a material cutting door. The partition board is vertically installed in the blanking barrel body, and a blanking cavity and an installation cavity are formed on both sides of the partition board; the material cutting door is rotatably installed at the bottom of the blanking cavity, and a driving device is installed in the installation cavity for driving the rotation of the material cutting door.

[0007] In this solution, a partition is arranged inside the blanking barrel body, dividing the space inside the blanking barrel into a blanking cavity and an installation cavity on the left and right sides. During use, the blanking cavity discharges materials normally, while the installation cavity is used to install a driving device, which drives a material cutting door installed at the bottom of the partition to seal the bottom of the blanking cavity. During blanking, the driving device drives the material cutting door to open, and normal blanking occurs; when blanking is not required, the driving device drives the material cutting door to rotate to temporarily close the bottom of the blanking cavity to prevent ash leakage problems. The structure of this device is simple. That is, adding a sealed material cutting door at the bottom of the blanking cavity can solve the ash leakage problem. Moreover, the driving device is inside the blanking barrel body, and the material cutting door is installed at the bottom of the blanking cavity, without occupying additional space; nor does it need to cooperate with other air suction devices, reducing the consumed energy. While solving the ash leakage problem, it reduces costs and improves the production efficiency of the enterprise.

[0008] Further, the driving device includes a cylinder, a connecting rod, and a connecting piece. The cylinder is installed in the installation cavity, and the cylinder has a cylinder rod; one end of the connecting piece is fixed on the material cutting door, and both ends of the connecting rod are respectively hinged to the cylinder rod and the connecting piece. When the cylinder rod contracts, it drives the connecting rod to rotate, indirectly driving the connecting piece to rotate, and at the same time the material cutting door opens; when the cylinder rod extends downward, under the driving of the rotation of the connecting rod, the connecting rod drives the material cutting door to rotate and seal at the bottom of the blanking cavity.

[0009] Further, there are at least two connecting pieces respectively, which are evenly installed on the material cutting door. When driven by the cylinder, the material cutting door rotates more stably and will not have problems such as skewing. The number of connecting rods corresponds to that of the connecting pieces.

[0010] Further, a hinge shaft is installed at the bottom of the partition, and the material cutting door is rotatably installed on the partition through the hinge shaft. Driven by the driving device, the material cutting door can rotate to open or close the bottom of the blanking cavity to prevent ash leakage problems when blanking is not required in the bag clamping mechanism.

[0011] Further, it also includes a stop collar. The stop collar is installed on the inner wall of the blanking barrel body, and the stop collar and the material cutting door are correspondingly installed, and the material cutting door is located inside the stop collar. The stop collar is similar to a door frame and is used in cooperation with the material cutting door. When the material cutting door is closed, it can play a good sealing role between the two; it also prevents the material cutting door from touching the inner wall of the blanking barrel body and causing damage when rotating. Further, a rubber ring can also be set on the stop collar to improve the sealing effect and reduce wear, etc.

[0012] Further, the material of the stop collar is round steel, and the diameter of the round steel is 4 mm - 6 mm, meeting the stiffness requirements, preventing continuous friction and damage during blanking, and can be used for a long time.

[0013] Furthermore, the bottom end of the partition plate is located below the stop collar, and the distance between the stop collar and the bottom end of the partition plate is 1 / 2 of the height of the stop collar. That is to say, the material cutting door is installed at the bottom of the partition plate, and the distance between the stop collar and the bottom end of the partition plate leaves a certain space for the rotation of the material cutting door; the material cutting door corresponds to the stop collar, and when the material cutting door rotates below the stop collar and abuts against the stop collar, it can completely play a sealing role and thoroughly solve the problem of ash leakage.

[0014] Furthermore, the material discharging barrel body is composed of a first barrel body and a second barrel body. The shape of the first barrel body is an inverted cone, the second barrel body is vertical, and the diameter of the second end of the first barrel body is the same as the diameter of the second barrel body; the diameter of the first end of the first barrel body is larger than the diameter of the second end, the first end of the first barrel body is the feeding port, and the end of the second barrel body far from the first barrel body is the discharging port; the material cutting door is installed at the second end of the first barrel body. The inverted cone-shaped barrel structure is convenient for material discharging. In order to facilitate the installation and use of the material discharging barrel body, a flange etc. can also be fixed on the first end of the first barrel body.

[0015] Furthermore, the installation cavity is internally communicated with the second barrel body. During use, the material discharging cavity discharges materials normally, and the installation cavity can also be used as an air flow channel to reduce the problem that the air flow flows back from the material discharging cavity upwards and causes dust to float at the feeding port.

[0016] Furthermore, the space size ratio of the material discharging cavity to the installation cavity is 3:1 to ensure sufficient material discharging space and not affect the normal material discharging work.

[0017] Adopting the above technical solutions, the utility model has the following beneficial effects:

[0018] (1) An installation cavity for installing a starting device is separated by a partition plate in the material discharging barrel body, and the driving device drives the material cutting door rotatably installed at the bottom of the partition plate to seal the bottom of the material discharging cavity, effectively preventing the problem of ash leakage;

[0019] (2) Specifically, the driving device includes a cylinder, a connecting rod and a connecting piece, which are hinged and rotatably connected to each other, and can pull the material cutting door to close and open;

[0020] (3) A stop collar corresponding to the material cutting door is arranged on the inner wall of the bottom wall of the material discharging cavity, which is similar to a door frame and plays a sealing effect when used in cooperation with the material cutting door;

[0021] (4) The installation cavity is communicated with the second barrel body, which can play a role in air flow balance during material discharging. Description of the Drawings
