Description

Technical Field

[0001] The utility model relates to the technical field of the production and processing of methyl octabromodiphenyl ether, in particular to an automatic packaging device for methyl octabromodiphenyl ether products. Background Art

[0002] Methyl octabromodiphenyl ether is an important brominated flame retardant, which is in the form of granules or powders at normal temperature. Its commonly used packaging materials include plastic-coated woven bags or paper-plastic composite bags, with a plastic bag lined inside to enhance the sealing performance. When packaging or using, it is necessary to avoid direct contact between methyl octabromodiphenyl ether and the skin and eyes of workers, so as to avoid harming the health of workers.

[0003] When the existing packaging equipment is in use, the height of its discharge port is usually in a fixed state. When granular or powdered products are poured into the packaging bag, due to the relatively high drop height, it is easy to cause powder dust. Especially for products such as methyl octabromodiphenyl ether, the powder diffuses into the surrounding environment, which is likely to harm the health of workers.

[0004] Therefore, we propose an automatic packaging device for methyl octabromodiphenyl ether products to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an automatic packaging device for methyl octabromodiphenyl ether products to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An automatic packaging device for methyl octabromodiphenyl ether products, including a storage barrel and a base. The storage barrel is supported above the base by a support frame. A fixed guide tube is connected to the outside of the discharge end of the storage barrel, and a movable guide tube is slidably sleeved around the fixed guide tube. The length of the movable guide tube and the fixed guide tube can be adjusted telescopically in the vertical direction. An exhaust fan is installed on the outer wall of the fixed guide tube near the top. One end of an air duct is connected to the air outlet end of the exhaust fan, and the other end of the air duct is communicated with a recovery box. A filter screen is installed on the outer wall of the recovery box.

[0008] In a further embodiment, a rack is connected to the outer wall of the movable guide tube in the vertical direction, and the rack is as long as the movable guide tube. A gear and a motor one are installed on one side of the support frame close to the rack, and the motor one drives the gear to rotate. The gear is meshed with the rack.

[0009] In a further embodiment, there is a clearance area between the bottom discharge pipe of the storage barrel and the top of the fixed guide tube, and the air inlet end of the exhaust fan faces the clearance area.

[0010] In a further embodiment, a diffusion hopper is installed in the bottom port of the movable material guiding cylinder through a cross bar. A second motor is fixed in the diffusion hopper, and a baffle is connected below the output shaft of the second motor through a connecting rod.

[0011] In a further embodiment, the axis line of the diffusion hopper coincides with the axis line of the movable material guiding cylinder.

[0012] In a further embodiment, the connecting rod is composed of a sleeve and an inner rod that are telescopically sleeved with each other, and the inner telescopic groove of the sleeve and the telescopic end of the inner rod adopt a non-circular structure that matches each other.

[0013] In a further embodiment, when the sleeve and the inner rod extend, the baffle extends out of the bottom port of the movable material guiding cylinder, and when the sleeve and the inner rod shorten, the baffle retracts into the bottom port of the movable material guiding cylinder.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By providing a fixed material guiding cylinder and a movable material guiding cylinder that are telescopically sleeved, the height of the discharge port of the storage cylinder can be adjusted during material discharging, so as to facilitate insertion into the packaging bag, effectively shortening the falling height of the discharged material, making it not easy to stir up powder dust during discharging and packaging. At the same time, the provided exhaust fan and recovery box can recover and process part of the powder dust, further reducing the diffusion of the powder dust to the surrounding environment, and thus being beneficial to improving the health protection effect on the staff during packaging operations.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1-2, An automatic packaging device for methyl octabromide ether products, including a storage hopper 1 and a base 2. The storage hopper 1 is used to hold methyl octabromide ether powder. The storage hopper 1 is supported above the base 2 by a support frame 3. The platform of the base 2 is used to place packaging bags. The outer connection of the discharge end of the storage hopper 1 is a fixed guide tube 4, and a movable guide tube 5 is slidably sleeved around the fixed guide tube 4. The length between the movable guide tube 5 and the fixed guide tube 4 can be adjusted telescopically in the vertical direction, so that the bottom port of the movable guide tube 5 can extend into the interior of the packaging bag, in order to reduce the height difference of the methyl octabromide ether powder falling from the bottom port of the movable guide tube 5 into the packaging bag, thereby reducing dust. At the same time, an exhaust fan 6 is installed on the outer wall of the fixed guide tube 4 near the top. One end of an air duct 7 is connected to the air outlet end of the exhaust fan 6, and the other end of the air duct 7 is connected to a recovery box 8. The recovery box 8 is installed in the middle of the support frame 3. A filter screen 81 is installed on the outer wall of the recovery box 8, so as to suck out part of the dust in the fixed guide tube 4 and transport it into the recovery box 8. The set filter screen 81 ensures the air pressure balance inside and outside the recovery box 8 and also prevents powder from overflowing from the recovery box 8.

[0028] Please refer to Figure 2 and Figure 4 , Considering that as the powder in the packaging bag increases, the bottom port of the movable guide tube 5 will be buried and it will be impossible to continue feeding. Therefore, a rack 9 is vertically connected to the outer wall of the movable guide tube 5, and the rack 9 is as long as the movable guide tube 5. A gear 10 and a first motor 11 are installed on one side of the support frame 3 close to the rack 9. The gear 10 is rotatably connected to the support frame 3 through a bearing seat, and the gear 10 is connected to the output shaft of the first motor 11 for driving the gear 10 to rotate. The gear 10 is meshed with the rack 9, so as to drive the rack 9 and the movable guide tube 5 to adjust the height up and down. Further, in actual use, in order to prevent the axial deflection of the movable guide tube 5 relative to the fixed guide tube 4 during adjustment, convex ribs are provided on the inner wall of the movable guide tube 5, and corresponding grooves are provided on the outer wall of the fixed guide tube 4 to limit the two.

[0029] Please refer to Figure 3 , In order to prevent the exhaust fan 6 from directly sucking the powder, a gap area 13 is provided between the bottom discharge pipe 12 of the storage hopper 1 and the top of the fixed guide tube 4. The air inlet end of the exhaust fan 6 faces the gap area 13, so that the air inlet end of the exhaust fan 6 does not face the falling powder.

[0030] Please refer to Figures 5-7, a diffusion hopper 15 is installed inside the bottom port of the movable material guiding cylinder 5 through a cross bar 14. The axis line of the diffusion hopper 15 coincides with the axis line of the movable material guiding cylinder 5. The diffusion hopper 15 can disperse the falling powder materials to prevent them from concentrating on one place. A second motor 16 is fixed inside the diffusion hopper 15. Below the output shaft of the second motor 16, a baffle 18 is connected through a connecting rod 17. By driving the baffle 18 to rotate through the second motor 16, the powder materials can be sliced and flattened, further preventing them from concentrating and piling up in one place, which is convenient for filling the packaging bag.

[0031] Furthermore, the connecting rod 17 is composed of a sleeve 171 and an inner rod 172 which are telescopically sleeved with each other. The inner telescopic groove of the sleeve 171 and the telescopic end of the inner rod 172 adopt a non-circular structure that matches each other, so that the sleeve 171 and the inner rod 172 can be telescopic, but there will be no problem of mutual deflection. The sleeve 171 is connected to the output shaft of the second motor 16, and the inner rod 172 is fixed to the center of the baffle 18. When the sleeve 171 and the inner rod 172 extend, the baffle 18 extends out of the bottom port of the movable material guiding cylinder 5, so that when spreading the powder materials, the powder materials diffuse around the outside of the movable material guiding cylinder 5. When the sleeve 171 and the inner rod 172 shorten, the baffle 18 retracts into the bottom port of the movable material guiding cylinder 5, so that when the bottom port of the movable material guiding cylinder 5 contacts the inner bottom of the packaging bag, the retraction of the baffle 18 into the movable material guiding cylinder 5 can be controlled.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
