Description

Technical Field

[0001] The utility model relates to the technical field of preform production, in particular to a gas source supply system on an empty bottle production line. Background Technique

[0002] Currently, plastic bottle bodies are usually made by blow molding machines. The structure of a blow molding machine generally includes a frame and a heating structure, a conveying structure, a blowing structure, and a mold clamping structure arranged on the frame. During processing, the plastic bottle body is first made into a preform using raw materials such as polyester, polyethylene, and polypropylene. Then, the heating structure softens the preform by heating, the conveying structure inputs the softened preform into the mold clamping structure, the blowing structure blows the preform clamped in the mold clamping structure, and finally, the formed container is taken away by a bottle taking device.

[0003] After patent retrieval, it is found that the publication number: CN219003809U discloses an automatic preform production line, which includes a detection device. A picking clamp is slidably arranged on the detection cross beam. A pre - detection workbench, a detection workbench, and a discharging workbench are sequentially arranged below the detection cross beam. There are corresponding picking clamps above the pre - detection workbench, the detection workbench, and the discharging workbench. A pre - detection support table is arranged on the pre - feeding workbench. Two detection support tables are slidably arranged at intervals on the detection workbench. A CCD detection camera is installed at the detection cross beam behind and above the detection workbench. During use, a pre - detection workbench is added, thus setting a buffer area for storing preforms. Even if defective products are detected, continuous feeding can be carried out and placed on the pre - detection workbench. Similarly, two detection support tables are set, and defective products can also be continuously detected through the reciprocating movement at intervals of the detection support tables without pausing the bottle feeding, increasing the detection efficiency.

[0004] The existing gas source pipeline of the automatic preform production line is long and dispersed for use throughout the entire empty transportation, resulting in a slow gas volume replenishment problem, which causes the telescopic speed of the air cylinder to be slow, and problems such as clamping deviation and missed clamping occur, affecting production efficiency and easily causing a collision problem of the filling machine. At the same time, to solve the above problems, a gas source supply system on an empty bottle production line is proposed in this application. Content of the Utility Model

[0029] Both ends of the first auxiliary air supply pipe 7 are movably connected with a first three-way connecting pipe 8. The second auxiliary air supply pipes 11 are symmetrically arranged, and both ends of the two second auxiliary air supply pipes 11 are connected to both ends of a second three-way connecting pipe 12.

[0030] It should be noted that the first auxiliary air supply pipe 7 and the second auxiliary air supply pipe 11 are respectively connected to the connecting rows. Both ends of the first auxiliary air supply pipe 7 are connected with a first three-way connecting pipe 8. Through the first three-way connecting pipe 8, a group of first auxiliary air supply pipes 7 can be divided into two groups of first air supply connecting pipes 9, which can increase the access amount to the cylinders. At the same time, through the first three-way connecting pipe 8 to divide the gas flow, when controlling the cylinders, the smoothness of the gas can be improved, and the sensitivity of the cylinder telescopic control can be enhanced. The two second auxiliary air supply pipes 11 are connected to both ends of the second three-way connecting pipe 12.
