Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a gas distribution device for a vacuum packaging machine. Background Art

[0003] In the process of implementing this solution, the inventors found that the following problems existed in the prior art and had not been well solved: when the vacuum suction tube was inserted into the packaging bag for suction, its end was hollow. If some materials were small in size and light in specific gravity, such as granular materials, they would be easily sucked into the trachea during suction, causing blockage. Utility Model Content

[0004] The main purpose of the utility model is to provide a gas distribution device for a vacuum packaging machine, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The gas distribution device of the vacuum packaging machine includes a main air pipe, a connecting air pipe is arranged below the main air pipe, an exhaust pipe is fixed at the bottom of the connecting air pipe, an internal threaded pipe is fixed at the bottom of the main air pipe, an inner pressure plate 1 is fixed to the bottom end of the inner wall of the internal threaded pipe, an inner pressure plate 2 is fixed to the inner bottom end of the exhaust pipe, a mesh plate is arranged on the top of the inner pressure plate 2, an upper pressure plate is arranged on the top of the mesh plate, a plurality of pressure rods are fixed on the top of the upper pressure plate, and an inner screw groove is drilled at the inner top end of the connecting air pipe.

[0007] Preferably, the internally threaded tube is inserted into the interior of the internal thread groove and threadedly connected thereto.

[0008] Preferably, a sealing ring is provided at the inner bottom end of the inner screw groove.

[0009] Preferably, the top of the internally threaded tube contacts the top of the sealing ring.

[0010] Preferably, the bottom of the inner pressure plate 1 is in contact with the tops of the plurality of pressure rods respectively.

[0011] Preferably, the bottom of the mesh plate contacts the top of the second inner pressure plate, and the bottom of the upper pressure plate contacts the top of the mesh plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the main air pipe, connecting air pipe and suction pipe are inserted into the packaging bag, the mesh plate is set at the top of the second inner pressure plate and the bottom of the upper pressure plate. When inhaling, the mesh plate can filter the material to avoid being adsorbed into the connecting air pipe and the main air pipe and causing blockage, thereby improving the efficiency of vacuuming.

[0014] 2. The main air pipe and the connecting air pipe can be separated by rotation. When they are spliced, the inner pressure plate 1 in the main air pipe can use the pressure rod to press down and stabilize the upper pressure plate, so that the upper pressure plate can be matched with the inner pressure plate 2 to press the screen plate to keep it stable during filtration and avoid displacement caused by suction. After they are separated, the upper pressure plate and the pressure rod can be directly taken out from the connecting air pipe and the exhaust pipe, and then the screen plate can be taken out from the upper pressure plate, so as to achieve the effect of being cleanable after disassembly, thereby maintaining the cleanliness during exhaust filtration.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5As shown, the gas distribution device of the vacuum packaging machine includes a main air pipe 1, a connecting air pipe 2 is provided below the main air pipe 1, an exhaust pipe 3 is fixed to the bottom of the connecting air pipe 2, an internal threaded pipe 11 is fixed to the bottom of the main air pipe 1, an inner pressure plate 12 is fixed to the bottom end of the inner wall of the internal threaded pipe 11, an inner pressure plate 2 31 is fixed to the inner bottom end of the exhaust pipe 3, a mesh plate 32 is provided on the top of the inner pressure plate 2 31, an upper pressure plate 4 is provided on the top of the mesh plate 32, a plurality of pressure rods 5 are fixed to the top of the upper pressure plate 4, and an inner screw groove 21 is drilled at the inner top end of the connecting air pipe 2.

[0023] Specifically, the internal threaded tube 11 is inserted into the internal thread groove 21 and threadedly connected thereto, which is convenient for disassembly.

[0024] Specifically, a sealing ring 6 is provided at the inner bottom end of the inner thread groove 21 , and the top of the inner threaded tube 11 contacts the top of the sealing ring 6 to ensure the sealing of the connection and avoid air leakage.

[0025] Specifically, the bottom of the inner pressure plate 12 is in contact with the tops of several pressure rods 5 respectively. When the main air pipe 1 and the connecting air pipe 2 are connected together, the inner pressure plate 12 can press down the pressure rods 5, so that the upper pressure plate 4 can press and hold the mesh plate 32.

[0026] Specifically, the bottom of the mesh plate 32 contacts the top of the second inner pressure plate 31 , and the bottom of the upper pressure plate 4 contacts the top of the mesh plate 32 , thereby ensuring the stability of the mesh plate 32 inside the exhaust pipe 3 .

[0027] When the air is sucked in, the mesh plate 32 can filter the material to avoid being adsorbed into the connecting air pipe 2 and the main air pipe 1 and causing blockage, thereby improving the working efficiency of the vacuum. The main air pipe 1 and the connecting air pipe 2 can be separated by rotation. When they are spliced, the inner pressure plate 12 in the main air pipe 1 can use the pressure rod 5 to press down and stabilize the upper pressure plate 4, so that the upper pressure plate 4 can cooperate with the inner pressure plate 2 31 to press the mesh plate 32 to maintain stability during filtration and avoid displacement caused by suction. After they are separated, the upper pressure plate 4 and the pressure rod 5 can be directly taken out from the connecting air pipe 2 and the suction pipe 3, and then the mesh plate 32 can be taken out from the upper pressure plate 4, so as to achieve the effect of being cleanable after disassembly, thereby maintaining the cleanliness during vacuum filtration.
