Description

Technical Field

[0001] The present application relates to the field of water charging equipment, and in particular to a charging equipment capable of preventing smoke and dust from overflowing. Background Art

[0002] In production and daily life, powdered materials such as industrial raw materials, food, and medicines often need to be packaged. This material packaging is accomplished by packaging equipment. During the packaging process, materials are usually packaged in fixed quantities by weight. Therefore, the accuracy and stability of the package weight are important indicators for evaluating the performance of packaging equipment. In addition, another indicator - dust prevention (dust removal) capability - can also reflect the performance of packaging equipment.

[0003] The utility model patent with announcement number CN210437424U proposes a loading dust-proof device for a filling machine, including an intermediate hopper and a lifting drive mechanism. The bottom end of the intermediate hopper is provided with a drop pipe extending downward. During the loading process, the drop port at the bottom of the drop pipe gradually moves away from the bottom of the inner cavity of the material container; an internal support and receiving mechanism is provided in the intermediate hopper.

[0004] The above-mentioned loading dust prevention device of the filling machine moves the material pipe close to the bottom of the inner cavity of the material container through the lifting drive mechanism to reduce the distance between the material and the bottom of the inner cavity of the material container. During the bagging process, since the distance between the upper and lower parts is small, the material falls into the material container at a lower speed, thereby greatly reducing the generation of dust; as the material accumulates, under the drive of the lifting drive mechanism, the intermediate hopper gradually moves away from the bottom of the inner cavity of the material container, so that the material can enter the material container without dust, avoiding the overflow of smoke and dust during loading, which causes pollution to the surrounding environment. The present application provides another solution to this problem. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, the present application provides a charging device that prevents smoke and dust from overflowing.

[0006] The present application provides a charging device for preventing smoke and dust from overflowing, which adopts the following technical solution:

[0007] A loading device for preventing smoke and dust from overflowing, comprising a silo, a discharge pipe fixedly connected to the bottom end of the silo, a dust-proof component provided on the discharge pipe for preventing smoke and dust from overflowing during loading, the dust-proof component comprising a plurality of V-shaped clamps hinged at the bottom end of the side wall of the discharge pipe and arranged in a circular array, the discharge pipe being located above the V-shaped clamp and provided with a pressure ring, the discharge pipe being located above the pressure ring and fixedly connected to a fixed disk, a plurality of springs in a circular array being fixedly connected to the lower surface of the fixed disk, the end of the spring away from the fixed disk being fixedly connected to the pressure ring, and the pressure ring abutting against the V-shaped clamp.

[0008] By adopting the above technical solution, when in use, the pressure ring is lifted upward to contract the spring, and the pressure ring is moved away from the V-shaped clamp. Then, the V-shaped clamp is swung to fold the bag opening of the loading bag onto the discharge pipe. Thereafter, the pressure ring is released to allow the spring to rebound and press the pressure ring downward, so that the pressure ring is brought into contact with the V-shaped clamp, and the V-shaped clamp clamps the bag opening of the loading belt, thereby minimizing the problem of smoke and dust overflowing during loading, which may pollute the surrounding environment.

[0009] Preferably, a limiting rod is provided in each of the springs, one end of the limiting rod is fixedly connected to the pressure ring, and the other end of the limiting rod passes through the fixed disk.

[0010] By adopting the above technical solution, the stability of the pressure ring can be improved through the limiting rod, preventing the pressure ring from shaking and causing the spring to twist and be damaged.

Then, one end of the connecting rod is passed through the connecting ring and plugged into the socket, which can prevent the spring from rebounding when the person releases the pressure ring, making it convenient to put the loading bag on the discharge pipe.

[0013] Preferably, an anti-slip component is fixedly connected to one end of the V-shaped clamping plate that abuts against the discharge pipe.

[0014] By adopting the above technical solution, the friction between the anti-slip component and the charging bag can be increased to prevent the charging bag from falling off the discharge pipe.

[0015] Preferably, a dust collecting box is fixedly connected to the top of the side wall of one side of the silo, an L-shaped dust collecting pipe is fixedly connected to the lower surface of the dust collecting box, an exhaust fan is installed on the L-shaped dust collecting pipe, and the end of the L-shaped dust collecting pipe away from the dust collecting box is close to the bottom end of the discharge pipe.

[0016] By adopting the above technical solution, when loading, the exhaust fan is started to make the L-shaped dust collecting pipe face the discharge pipe and the bag opening of the charging bag to exhaust air, so that the smoke and dust raised from the gap of the bag opening during loading can be sucked into the dust collecting box to prevent some of the smoke and dust from overflowing.

[0017] Preferably, the bottom end of the dust collecting box is inclined and communicated with the silo.

[0018] By adopting the above technical solution, the dust of the material drawn into the dust collecting box can be discharged into the material bin for continued use, thus avoiding waste.

[0020] By adopting the above technical solution, the stability of the L-shaped dust collecting pipe can be improved by the fixing rod and the fixing ring to prevent shaking.

[0021] Preferably, one end of the L-shaped dust collecting pipe close to the discharge pipe is fixedly connected to a dust collecting hood.

[0022] By adopting the above technical solution, the overflowed smoke and dust can be conveniently collected through the dust collecting hood.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The present invention adopts the coordinated arrangement between the V-shaped clamp, the pressure ring and the spring. When in use, the pressure ring is lifted upward to contract the spring and move the pressure ring away from the V-shaped clamp. Then the V-shaped clamp is swung to fold the bag opening of the loading bag onto the discharge pipe. Then the pressure ring is released to allow the spring to rebound and press the pressure ring downward, so that the pressure ring abuts against the V-shaped clamp, and the V-shaped clamp clamps the bag opening of the loading belt, thereby minimizing the problem of smoke and dust overflowing during loading and polluting the surrounding environment.

[0025] 2. When loading, start the exhaust fan and make the L-shaped dust collecting pipe face the discharge pipe and the bag opening of the charging bag to exhaust air. This can draw the smoke and dust raised from the gap of the bag opening during loading into the dust collecting box to prevent some of the smoke and dust from overflowing.

[0030] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0031] The embodiment of the present application discloses a charging device that prevents smoke and dust from overflowing.

[0032] Reference Figure 1 and Figure 2 The bag is then loaded onto the loading platform 2 and the loading platform 2 is moved upwards to release the bag from the loading platform 2 so that the bag can be loaded onto the loading platform 2.

[0033] Reference Figure 2 A limiting rod 7 is provided in the spring 6, one end of the limiting rod 7 is fixedly connected to the pressure ring 4, and the other end of the limiting rod 7 passes through the fixed disk 5. The limiting rod 7 can improve the stability of the pressure ring 4 and prevent the pressure ring 4 from shaking, which may cause the spring 6 to twist and be damaged.

[0034] Reference Figure 2 The discharge pipe 2 is located above the fixed plate 5 and is provided with a connecting ring 8. A connecting rod 9 is provided on one side wall of the connecting ring 8. A socket 10 is provided on the side wall of the discharge pipe 2 close to the connecting rod 9. One end of the connecting rod 9 passes through the connecting ring 8 and is plugged into the socket 10. When the pressure ring 4 is pushed upward, the limit rod 7 will drive the connecting ring 8 to move upward so that the connecting rod 9 and the socket 10 are in the same horizontal plane. After that, one end of the connecting rod 9 passes through the connecting ring 8 and is plugged into the socket 10. This can prevent the spring 6 from rebounding when the person releases the pressure ring 4, making it convenient to put the charging bag on the discharge pipe 2.

[0035] Reference Figure 3 The end of the V-shaped splint 3 that abuts the discharge pipe 2 is fixedly connected with an anti-slip component 11. The anti-slip component 11 can be an anti-slip tooth plate. The side of the anti-slip tooth plate close to the discharge pipe 2 is toothed. The anti-slip tooth plate is arc-shaped and adapted to the side wall of the discharge pipe 2. The arc-shaped anti-slip tooth plate can increase the contact area between the anti-slip tooth plate and the discharge pipe 2. The contact between the toothed anti-slip tooth plate and the charging bag can increase the friction between the charging bag and the charging bag, thereby preventing the charging bag from falling off the discharge pipe 2.

[0036] Reference Figure 1A dust collecting box 12 is fixedly connected to the top of the side wall of one side of the silo 1. A plurality of air holes for discharge are opened on the top of the collecting box 12. Filters are installed in the air holes to prevent smoke and dust from being discharged from the air holes. An L-shaped dust collecting pipe 13 is fixedly connected to the lower surface of the dust collecting box 12. An exhaust fan 14 is installed on the L-shaped dust collecting pipe 13. One end of the L-shaped dust collecting pipe 13 away from the dust collecting box 12 is close to the bottom end of the discharge pipe 2. When loading, by starting the exhaust fan 14, the L-shaped dust collecting pipe 13 is exhausted towards the discharge pipe 2 and the bag opening of the charging bag, so that the smoke and dust raised from the gap of the bag opening during loading can be sucked into the dust collecting box 12 to prevent some smoke and dust from overflowing.

[0037] Reference Figure 1 The bottom end of the dust box 12 is tilted and connected to the silo 1, so that the dust of the material drawn into the dust box 12 can be discharged into the silo 1 for continued use to avoid waste.

[0038] Reference Figure 1 A plurality of fixing rods 15 are fixedly connected to the side wall of the silo 1 close to the L-shaped dust collecting pipe 13, and a fixing ring 16 is fixedly connected to the end of the fixing rod 15 away from the silo 1. The fixing ring 16 is sleeved on the L-shaped dust collecting pipe 13. The fixing rods 15 and the fixing ring 16 can improve the stability of the L-shaped dust collecting pipe 13 and prevent shaking.

[0039] Reference Figure 1 One end of the L-shaped dust collecting pipe 13 close to the discharge pipe 2 is fixedly connected to a dust collecting cover 17, which facilitates the collection of overflowing smoke and dust.

[0040] The implementation principle of the loading equipment for preventing smoke and dust from overflowing in the embodiment of the present application is as follows: when in use, the pressure ring 4 is lifted upward to contract the spring 6, and the pressure ring 4 is moved away from the V-shaped clamp 3, and then the V-shaped clamp 3 is swung to fold the bag opening of the charging bag and put it on the discharge pipe 2, and then the pressure ring 4 is loosened to make the spring 6 rebound and press the pressure ring 4 downward, so that the pressure ring 4 is abutted against the V-shaped clamp 3, so that the V-shaped clamp 3 clamps the bag opening of the charging belt, thereby avoiding smoke and dust overflowing during loading and polluting the surrounding environment as much as possible.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
