[0060] The following are specific embodiments of the present technical solution, and the technical solution of the present technical solution is further described in conjunction with the accompanying drawings, but the present technical solution is not limited to these embodiments.

[0061] like Figure 1-Figure 3As shown, a plastic bottle discharging mechanism with air-conveying cooling function comprises:

[0062] A bottle fixing assembly 2, which is used to fix the bottles 11 in a row;

[0063] A discharge track 3, which is arranged at one end of the bottle fixing assembly 2, and the direction of the discharge track 3 is consistent with the arrangement direction of the bottles 11;

[0064] The air delivery component is used to blow the bottle body 11 on the bottle body fixing component 2 onto the discharge track 3.

[0065] The bottle fixing assembly 2 comprises:

[0066] A fixed plate 21, which is fixedly arranged on the workbench 1;

[0067] A second fixing plate 22, which is hinged on the workbench 1;

[0068] The driving cylinder 1 41 is connected to the fixing plate 22 , and the driving cylinder 1 41 is used to drive the fixing plate 22 to rotate.

[0069] When the driving cylinder 1 41 drives the fixing plate 2 22 to be in a vertical state, the bottle body fixing assembly 2 is in a clamping state, and a clamping position 25 for clamping and fixing the bottle body 11 is formed between the fixing plate 1 21 and the fixing plate 2 22 .

[0070] When the driving cylinder 1 41 drives the fixing plate 2 22 to unfold, the bottle fixing assembly 2 is in a loading state. At this time, the bottle fixing assembly 2 waits for other devices to transport the bottle 11 to the clamping position 25 .

[0071] like Figure 1-Figure 3 As shown, the edge of the fixing plate 1 21 is inclined upward to form a supporting edge 1 23, and the edge of the fixing plate 2 22 is inclined upward to form a supporting edge 24. By providing the supporting edge 1 23 and the supporting edge 24, the lower ends of the fixing plates 1 21 and 22 can be formed with sufficient avoidance space, so that the fixing plates 1 21 and 22 can fix the bottle body 1.

[0072] The upper ends of the first supporting edge 23 and the second supporting edge 24 are used to cooperate with each other to abut against the convex edge 12 of the bottle body 11 to support the bottle body 11 to the clamping position 25.

[0073] like Figure 1-Figure 3 As shown, a guide rod 1 31 and a guide rod 2 32 are provided on the discharge track 3, and the guide rod 1 31 and the guide rod 2 32 abut against the lower end of the bottle body 11, thereby reducing the shaking of the bottle body 11 when moving.

[0074] like Figure 1-Figure 3As shown, the second fixing plate 22 is arranged on the articulated frame 4, and the articulated frame 4 is hinged on the workbench 1 through the articulated seat 44, and rotates around the articulated seat 44; the driving cylinder 1 41 is connected to the articulated frame 4, and can drive the articulated frame 4 to rotate;

[0075] The hinged frame 4 is also provided with a reset spring 42, which is used to drive the hinged frame 4 to reset quickly, thereby ensuring that when other devices transport the bottle body 11 to the clamping position 25, the bottle body 11 will not be blocked by the hinged frame 4 and the fixing plate 22, and can smoothly enter the clamping position 25.

[0076] A guide rod 3 43 is also provided on the articulated frame 4. When the articulated frame 4 is in a vertical state, the guide rod 3 43 can abut against one side of the bottle body 11 to prevent the bottle body 11 from shaking during movement.

[0077] like Figure 1-Figure 3 As shown, a support 13 is provided on the workbench 1, and the support 13 and the discharge track 3 are respectively arranged at two ends of the bottle body 11 arrangement direction;

[0078] The air delivery assembly includes an air jet part 5 and an air supply pipe 51 connected to the air jet part 5, which is arranged on the bracket 13. The air supply pipe 51 is used to blow the bottle body 11 on the bottle body fixing assembly 2 onto the discharge track 3. Since the bottle body 11 after blow molding still has a certain residual temperature, the bottle body 11 is still easily deformed due to collision during this period. In the present technical solution, during the process of discharging the bottle body 11, the bottle body 11 is blown onto the discharge track 3 by setting an air delivery assembly. When the high-speed airflow contacts the bottle body 11, it will generate stronger convective heat transfer with the bottle body 11, thereby increasing the heat dissipation of the bottle body 11. Since the guide rod 1 31, the guide rod 2 32 and the guide rod 3 43 are continuous long rods, they can be against the side of the bottle body 11 for a long time, and will not suddenly collide with the side wall of the bottle body 11, thereby avoiding deformation of the side of the bottle body 11.

[0079] At the same time, the airflow ejected by the jet part 5 will drive the additional air flow of the device, thereby taking away the heat near the device, so that the temperature near the discharge track 3 is maintained at a relatively constant temperature. The efficiency of heat conduction between the bottle body 11 and the surrounding air is guaranteed to be constant. When the bottle body 11 moves on the discharge track 3, it will also generate strong convection heat exchange with the air, and heat conduction with the air in a larger space, further reducing the temperature rise near the discharge track 3 and ensuring the efficiency of heat dissipation.

[0080] like Figure 1-Figure 3 As shown, a strip hole 16 is formed on the bracket 13 , and the strip hole 16 is used to adjust the height of the upper end of the bracket 13 extending out of the workbench 1 , so as to change the height of the air injection part 5 to match bottles 11 of different shapes.

[0081] like Figure 1-Figure 3 As shown, a drop hole 15 is opened on the workbench 1, and the drop hole 15 is located below the clamping position 25. When an unqualified bottle body 11 cannot be placed on the clamping position 25, the unqualified bottle body 11 will fall off from the clamping position 25 and fall from the drop hole 15 into the collection container under the table for easy recycling.

[0082] like Figure 1-Figure 5 A plastic bottle production line shown includes a plastic bottle discharging mechanism as described above;

[0083] It also includes a material unloading mechanism, which is used to transport the bottles 11 on the assembly line 14 to the material unloading mechanism.

[0084] like Figure 4 and Figure 5 As shown, the unloading mechanism includes:

[0085] The clamping assembly 6 is used to clamp the bottle 11 from the assembly line 14 and send the bottle 11 to the clamping position 25 so that the bottle fixing assembly 2 can complete the fixing of the bottle 11;

[0086] The shifting assembly 7 and the clamping assembly 6 are arranged on the shifting assembly 7 , and the shifting assembly 7 is used to drive the clamping assembly 6 to approach or move away from the bottle body 11 fixing device.

[0087] Further, the clamping assembly 6 comprises:

[0088] A clamping cylinder 61, which is used to clamp and fix the bottle body 11;

[0089] A rotating shaft 62, on which the clamping cylinder 61 is sleeved;

[0090] A driving motor 63, which is disposed at one end of the rotating shaft 62, and is used to drive the rotating shaft 62 to rotate;

[0091] a balancing weight 64, which is disposed on the other end of the rotating shaft 62;

[0092] A lifting platform 65, on which the rotating shaft 62 is disposed;

[0093] A driving cylinder 3, which is used to drive the lifting platform 65 to move up and down in the vertical direction;

[0094] The shifting assembly 7 comprises:

[0095] A mounting frame 71, on which the clamping assembly 6 is disposed;

[0096] The second driving cylinder 72 has a push rod connected to the lower end of the mounting frame 71, so that the second driving cylinder 72 can drive the mounting frame 71 to move;

[0097] A guide rail 73, which is arranged on the workbench 1;

[0098] A slide seat 74 is provided at the lower end of the mounting frame 71 , and the slide seat 74 is sleeved on the guide rail 73 .

[0099] The above embodiments are only preferred embodiments of the present technical solution, and are not intended to limit the protection scope of the present technical solution. Therefore, any equivalent changes made based on the structure, shape, and principle of the present technical solution should be included in the protection scope of the present technical solution.
