Description

Technical Field

[0001] This utility model relates to the field of conveying system technology, and in particular to exchangers. Background Technology

[0002] To improve the speed of raw material changes in blow molding machines, multiple independent feeding systems are typically set up in actual production. When it's necessary to change the raw material for the blow molding machine, simply connect the different feeding systems directly to the machine. The feeding systems and the blow molding machine are connected via pipes for material transport. When changing the feeding system connected to the blow molding machine, the previously connected pipe needs to be disconnected, and a new pipe needs to be installed. Pipe disassembly and installation take time, during which the blow molding machine must stop operating while waiting for the pipe replacement to complete, impacting its efficiency.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0029] Example 1

[0030] Figure 1 A three-dimensional structural schematic diagram of the switch according to Embodiment 1 of this disclosure is shown. Figure 2 A cross-sectional view of the upper fixed plate and the upper moving plate at point A is shown in the exchanger of Embodiment 1 of this disclosure. Please refer to... Figure 1 and Figure 2 The exchanger includes a fixed frame 1 with a first air inlet 121 and a first air outlet 111. Different dispensing systems can connect to different first air inlets 121 on the fixed frame 1. A movable frame 2 is mounted on the fixed frame 1. The movable frame 2 is equipped with a straight pipe assembly 21 and an exchange pipe assembly 22. The movable frame 2 has at least four second air outlets 231 and at least four second air inlets 241. One pipe 211 is individually connected to one second air inlet 241 and one second air outlet 231. Rollers 3 are rotatably connected to the movable frame 2. The movable frame 2 rolls against the fixed frame 1 via the rollers 3, reducing friction between the movable frame and the fixed frame 1 and facilitating the switching of pipe 211 connections. The straight pipe assembly 21 and the exchange pipe assembly 22 each have at least two pipes 211. One pipe 211 is individually connected to one first air inlet 121 and one first air outlet 111. The pipes 211 in the straight-through pipe assembly 21 are arranged in parallel, while the pipes 211 in the exchange pipe assembly 22 are arranged in a crisscrossing manner. Different first air inlets 121 and second air inlets 241, and different first air outlets 111 and second air outlets 231 are aligned relative to the sliding fixed frame 1 and the movable frame 2, to switch the connection between the pipes 211 in the straight-through pipe assembly 21 or the pipes 211 in the exchange pipe assembly 22 and the first air inlet 121 and the first air outlet 111, thereby switching the material received by the blow molding machine connected to the first air outlet 111. This switching process is rapid, effectively reducing downtime when the blow molding machine switches materials and improving the working efficiency of the blow molding machine.

[0031] Please refer to Figure 1 and Figure 2The fixed frame 1 includes an upper fixed plate 11 with a first air outlet 111 and a lower fixed plate 12 with a first air inlet 121. The movable frame 2 includes an upper movable plate 23 with a second air outlet 231 and a lower movable plate 24 with a second air inlet 241. A first wheel set 31 is provided on the upper movable plate 23. The upper fixed plate 11 is located between the upper movable plate 23 and the first wheel set 31. A second wheel set 32 ​​is provided on the lower movable plate 24. The lower fixed plate 12 is located between the lower movable plate 24 and the second wheel set 32. The upper fixed plate 11 and the lower fixed plate 12 are clamped and fixed from opposite sides, thus fixing the movable frame 2 on the fixed frame 1. The rollers 3, including the first wheel set 31 and the second wheel set 32, roll together in contact with the fixed frame 1, enhancing the connection stability between the movable frame 2 and the fixed frame 1. Specifically, when the straight pipe assembly 21 connects the first air inlet 121 and the first air outlet, the upper fixing plate 11 blocks the second air outlet 231 connecting the inner pipe 211 of the exchange pipe assembly 22, and the lower fixing plate 12 blocks the second air inlet 241 connecting the inner pipe 211 of the exchange pipe assembly 22. When the exchange pipe assembly 22 connects the first air inlet 121 and the first air outlet, the upper fixing plate 11 blocks the second air inlet 241 connecting the inner pipe 211 of the straight pipe assembly 21, and the lower fixing plate 12 blocks the second air inlet 241 connecting the inner pipe 211 of the straight pipe assembly 21. When switching the positions of the straight pipe assembly 21 and the exchange pipe assembly 22, the upper fixing plate 11 blocks all the second air outlets 231, and the lower fixing plate 12 blocks all the second air inlets 241 to prevent material leakage.

[0032] Preferably, a pad 25 is provided on the upper movable plate 23 and the lower movable plate 24 respectively. The pad 25 is connected to the upper movable plate 23 / lower movable plate 24 by bolts 252. The upper movable plate 23 and the lower movable plate 24 support the first wheel set 31 and the second wheel set 32 ​​respectively by the pad 25. This allows the upper fixing plate 11 to be disposed between the upper movable plate 23 and the first wheel set 31, and the lower fixing plate 12 to be disposed between the lower movable plate 24 and the second wheel set 32.

[0033] More preferably, two pads 25 are respectively provided on the upper movable plate 23 and the lower movable plate 24. A connecting rod 251 is provided between the two pads 25. The roller 3 is rotatably connected to the connecting rod 251. Specifically, the connecting rod 251 is inserted into the pad 25. The roller 3 is rotatably connected to the connecting rod 251 through a bearing (not shown in the figure). This achieves a rolling connection between the movable frame 2 and the fixed frame 1.

[0034] Please refer to Figure 1 and Figure 2 The roller 3 rolls along its direction. An actuator cylinder 4 is mounted on the fixed frame 1 and connected to the movable frame 2. The movable frame 2 is moved by extending and retracting the actuator cylinder 4, thus enhancing the intelligence level of the exchanger in this application and facilitating automation.

[0035] Preferably, when the straight-through pipe group 21 and the exchange pipe group 22 are each provided with at least three pipes 211, the exchange pipe group 22 can be provided with two or more groups along the rolling direction of the roller 3. This provides more pipe 211 switching options, improves the flexibility of pipe 211 switching, and adapts to more operating conditions.

[0036] More preferably, a limiting block 13 is also provided on the fixed frame 1. The limiting block 13 is disposed on the rolling path of the roller 3 to limit the travel of the movable frame 2 and prevent the movable frame 2 from detaching from the fixed frame 1.

[0037] The specific workflow of this utility model is as follows:

[0038] The conveying pipes of different batching systems are respectively connected to the first air inlet 121, and the different feeding pipes of the blow molding machine are respectively connected to the first air outlet 111. The pipe 211 in the straight pipe group 21 is driven by the actuating cylinder 4 to connect the first air outlet 111 and the first air inlet 121, so as to connect the conveying pipe and the feeding pipe.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
