Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust cleaning equipment for the surface of bagged cement, in particular to a blowing mechanism for a bag cleaning machine. Background Technique
[0002] When bagged cement is filled and falls from the packaging machine, a lot of cement dust adheres to the surface of the cement bag. If not cleaned, dust will be generated during transportation, loading, and transportation, causing environmental pollution and affecting the health of workers. Therefore, after the cement is bagged, it is necessary to blow and clean the cement bag.
[0003] At present, when the existing bag cleaning machine blows and cleans the cement bag, the air outlet above the cement bag is fixed. When encountering an unleveled cement bag, it will get stuck and block the subsequent cement bags in the bag cleaning machine, resulting in the shutdown of the entire packaging line. Cleaning the blocked cement bag is very troublesome and affects production. Summary of the Utility Model
[0004] The embodiment of the utility model provides a blowing mechanism for a bag cleaning machine, which has the technical effect that the air outlet above the cement bag can rotate and will not get stuck with the cement bag.
[0005] A blowing mechanism for a bag cleaning machine adopts the following technical solutions:
[0006] A blowing mechanism for a bag cleaning machine includes a high-pressure blower fixed on the top of the dust collection cover of the bag cleaning machine. A fixed upper air outlet seat communicating with the air outlet of the high-pressure blower is connected to the dust collection cover of the bag cleaning machine. An upper air outlet is arranged below the fixed upper air outlet seat. One side of the upper air outlet is rotatably connected to the side wall of the fixed upper air outlet seat. A return spring is fixed between the side wall of the upper air outlet and the dust collection cover of the bag cleaning machine. When an unleveled cement bag passes below the upper air outlet, the cement bag pushes the upper air outlet to rotate upward. After the cement bag passes through the upper air outlet, the return spring can reset the upper air outlet.
[0007] Furthermore, side air outlets are arranged on both sides below the upper air outlet. The side air outlets are connected to the upper air outlet through corrugated hoses, and the size of the air outlet of the upper air outlet can be adjusted.
[0008] Furthermore, spoiler plates are installed inside the upper air outlet (2) and the side air outlets (3). Ventilation holes are opened on the spoiler plates, and air passes through the ventilation holes.
[0009] Compared with the prior art, the utility model has the following technical effects:
[0010] The utility model is provided with a three-sided air blowing mechanism. The air flow generated by the fan can not only blow the cement bags from three directions, but also the air blowing ports can be installed at a relatively low height, shortening the distance from the air blowing ports to the cement bags, and being able to blow off the dust on the surface of the cement bags at a relatively high wind speed. If an unleveled cement bag hits the upper air blowing port, the upper air blowing port can rotate to avoid the cement bag, and after the unleveled cement bag passes, the air blowing port returns to the initial position under the action of the spring.

Detailed Embodiment
[0019] To make the purpose, technical solution and advantages of the utility model more clear and understandable, the utility model will be further described in detail below in combination with the embodiments and the drawings. Herein, the illustrative embodiments of the utility model and their descriptions are used to explain the utility model, but do not limit the utility model.
[0020] Refer to Figures 1-5, A blowing mechanism for a bag cleaning machine, including a high-pressure blower 1 fixed on the top wall of the dust collection hood 12 of the bag cleaning machine. At the air outlet of the high-pressure blower 1, a blower connection cylinder 11 is fixedly connected through a flange. The blower connection cylinder 11 is fixed on the dust collection hood 12 of the bag cleaning machine. Below the blower connection cylinder 11, an upper air blowing port fixing seat 13 is fixed, and the upper air blowing port fixing seat 13 is internally connected to the blower connection cylinder 11.
[0021] Below the upper air blowing port fixing seat 13, an upper air blowing port 2 is connected. On one side of the upper air blowing port 2, a rotating shaft 21 is fixed. The rotating shaft 21 is rotatably connected to the upper air blowing port fixing seat 13, and the upper air blowing port 2 can rotate around the rotating shaft 21. On the side wall of the upper air blowing port fixing seat 13, a limiting plate for limiting the upper air blowing port 2 is fixed. The limiting plate can prevent the upper air blowing port 2 from rotating upwards too much and thus being unable to reset.
[0022] A reset spring 22 is fixed between the upper air blowing port 2 and the dust collection hood 12 of the bag cleaning machine. When the reset spring 22 is in a normal state, the upper air blowing port 2 is in a vertical state, and the air outlet of the upper air blowing port 2 faces vertically downwards. When an unleveled cement bag 4 passes below the upper air blowing port 2, the cement bag 4 will push the upper air blowing port 2 to rotate along the rotating shaft 21, and the reset spring 22 is stretched. When the cement bag 4 passes the upper air blowing port 2, the upper air blowing port 2 returns to the vertical state under the action of the reset spring 22.
[0023] On both sides below the upper air blowing port 2, side air blowing ports 3 are provided. A corrugated pipe 31 is connected between the side air blowing ports 3 and the upper air blowing port 2. The corrugated pipe 31 is fixed to the upper air blowing port 2 through a clamp, and the corrugated pipe 31 is fixed to the side air blowing port 3 through a clamp.
[0024] The upper air blowing port 2 is composed of an iron plate. The upper air blowing port 2 includes a communicating pipe 23, fixed side walls 24, and a movable side wall 25. The corrugated pipe 31 is installed on the side wall of the communicating pipe 23. Three fixed side walls 24 and one movable side wall 25 are all fixed below the communicating pipe 23. The three fixed side walls 24 and one movable side wall 25 enclose a closed space with openings at the top and bottom and closed on all sides. The three fixed side walls 24 are fixedly connected in sequence, and the movable side wall 25 is clamped between two fixed side walls 24. On both sides of the movable side wall 25, connecting plates 26 are fixed. Waist-shaped holes 261 are opened on the connecting plates 26. Locking bolts 27 are provided on the connecting plates 26. The locking bolts 27 pass through the waist-shaped holes 261 and penetrate the fixed side walls 24 and are threadedly connected with locking nuts 28.
[0025] The size of the air outlet of the upper air outlet 2 can be adjusted. When the air outlet of the upper air outlet 2 needs to be reduced, the movable side plate is moved to move the bottom of the movable side wall 25 to the inside of the upper air outlet 2, thereby reducing the size of the air outlet of the upper air outlet 2. After the movable side wall 25 is moved, the movable side wall 25 and the fixed side wall 24 are fixed by the locking bolt 27 and the locking nut 28. A spoiler is fixed on the inner wall of the connecting pipe 23. The four side walls of the spoiler are fixed to the four inner walls of the connecting pipe 23. The spoiler is a flat plate. Ventilation holes are evenly opened on the spoiler, and the wind passes through the ventilation holes. The setting of the spoiler makes the blown airflow more concentrated and the wind speed faster.
[0026] The implementation principle of the blower mechanism for bag cleaning machine of the utility model is as follows: the airflow generated by the high-pressure blower 1 enters the upper blowing port 2 through the blower connecting tube 11 and the upper blowing port fixing seat 13, and a part of the airflow in the upper blowing port 2 is blown downward through the upper blowing port 2 to clean the dust on the upper surface of the cement bag 4. A part of the airflow enters the side blowing port 3 through the blowing ports and the bellows 31 on both sides of the upper blowing port 2, and is blown toward the middle through the side blowing port 3 to clean the dust on both sides of the cement bag 4. When the cement bag 4 passes through the blowing port normally, the three-sided airflow blows toward the cement bag 4 to clean the dust on the top and two sides of the cement bag 4. When the unflattened cement bag 4 hits the upper blowing port 2, the upper blowing port 2 rotates obliquely upward around the upper blowing port 2 rotating shaft 21 under the action of the cement bag 4 to avoid the cement bag 4. When the cement bag 4 passes, the upper blowing port 2 returns to its original position under the action of the reset spring 22.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
