[0002] The foam pre-expander is mainly used for producing plastic foam. In the production process of plastic foam, raw materials need to be put into the foam barrel of the pre-expander for uniform cutting and overall foaming expansion of the raw materials, so that the volume of individual particles of the foam raw materials increases several times, and then the materials are discharged and formed. The foam pre-expander is an important link in the production process of plastic foam.

[0003] In the prior art, the publication number CN213533470U discloses an automatic stirring device for a foam pre-expander, which includes a stirring barrel.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present invention provides a full-automatic foam pre-expander, including:

[0035] The lower housing 1 of the pre-foaming machine is fixedly provided with a power motor 2 at the bottom end. The output end of the power motor 2 is fixedly provided with a stirring shaft 3, and a stirring blade 4 is installed on the stirring shaft 3. It should be noted that by starting the power motor 2, the stirring shaft 3 can drive the stirring blade 4 to rotate, so as to stir the foaming granules.

[0036] A disassembly, assembly and cleaning component is arranged on the lower housing 1 of the pre-foaming machine. The disassembly, assembly and cleaning component includes the upper housing 5 of the pre-foaming machine, an insertion rod 6, a screw rod 8, a threaded cylinder 9, an ejector rod 13, a fixing bolt 14, a limiting disc 10 and a counterweight pin 11. The insertion rod 6 is fixedly installed at the bottom end of the upper housing 5 of the pre-foaming machine. An insertion slot 7 is opened at the top end of the lower housing 1 of the pre-foaming machine, and the insertion rod 6 is clamped with the insertion slot 7. It should be noted that in this way, the upper housing 5 of the pre-foaming machine can be limited.

[0037] The screw rod 8 is fixedly installed at the top end of the stirring shaft 3. The threaded barrel 9 is rotatably installed on the upper shell 5 of the pre-foaming machine. The screw rod 8 is threadedly connected to the threaded barrel 9. The ejector rod 13 is fixedly installed at the top end of the screw rod 8. The threaded barrel 9 and the ejector rod 13 are fixedly connected by a fixing bolt 14. The limiting disc 10 is fixedly sleeved on the outer side of the threaded barrel 9. A pin slot 12 is formed at the top end of the upper shell 5 of the pre-foaming machine, and the weight pin 11 is engaged with the pin slot 12.

[0038] Through the above disassembly and cleaning assembly, when it is necessary to clean the inside of the pre-foaming machine, the weight pin 11 can be inserted into the pin slot 12, and the fixing bolt 14 can be removed. Then, the power motor 2 is started, which can make the stirring shaft 3 drive the screw rod 8 to rotate. At this time, the threaded barrel 9 cannot rotate. Therefore, through the cooperation of the screw rod 8 and the threaded barrel 9, the threaded barrel 9 can move upward, and the upper shell 5 of the pre-foaming machine can also move upward until the screw rod 8 is removed from the threaded barrel 9. Then, the upper shell 5 of the pre-foaming machine can be removed, and at this time, it is convenient to clean the inside of the pre-foaming machine, which is relatively convenient to use.

[0039] Specifically, a foaming granule feeding hopper 15 is fixedly arranged at the top end of the upper shell 5 of the pre-foaming machine. A discharge pipe 16 is fixedly arranged at the bottom end of the lower shell 1 of the pre-foaming machine. A valve is installed on the discharge pipe 16. It should be noted that it is convenient for feeding and discharging.

[0040] Specifically, a support frame 18 is fixedly arranged at the bottom end of the lower shell 1 of the pre-foaming machine. Two steam inlet pipes 17 are fixedly arranged on the lower shell 1 of the pre-foaming machine. It should be noted that it is convenient for introducing high-temperature steam.

[0041] Specifically, the top end of the lower shell 1 of the pre-foaming machine is in contact with the upper shell 5 of the pre-foaming machine. A sealing gasket 19 is embedded at the bottom end of the upper shell 5 of the pre-foaming machine. The sealing gasket 19 is in sealing contact with the lower shell 1 of the pre-foaming machine. It should be noted that the sealing performance at the connection between the lower shell 1 and the upper shell 5 of the pre-foaming machine can be ensured.

[0042] Specifically, a bearing is fixedly arranged on the lower shell 1 of the pre-foaming machine. The threaded barrel 9 is installed in the bearing. The end of the limiting disc 10 is in contact with the upper shell 5 of the pre-foaming machine. It should be noted that the threaded barrel 9 can rotate stably.

[0043] Specifically, a pin hole is formed in the upper limiting disc 10, and the weight pin 11 is engaged with the pin hole. It should be noted that it is convenient to limit the limiting disc.

[0044] Specifically, a sealing ring is installed inside the lower shell 1 of the pre-foaming machine. The stirring shaft 3 is in sealing contact with the inner side of the sealing ring. It should be noted that the sealing performance between the stirring shaft 3 and the lower shell 1 of the pre-foaming machine is ensured.

[0045] Working principle:

[0046] S1: When stirring the foaming particles, start the power motor 2, which can make the stirring shaft 3, the screw 8 and the threaded cylinder 9 rotate synchronously. At this time, the counterweight pin 11 is removed.

[0047] S2: After the foaming particles are stirred and the inside of the pre-expander needs to be cleaned, the counterweight pin 11 can be inserted into the pin slot 12, and the fixing bolt 14 can be removed. Then start the power motor 2, which can make the stirring shaft 3 drive the screw 8 to rotate. At this time, the threaded cylinder 9 cannot rotate. Therefore, through the cooperation of the screw 8 and the threaded cylinder 9, the threaded cylinder 9 can move upward, and the upper shell 5 of the pre-expander can also move upward until the screw 8 moves out of the threaded cylinder 9. Then the upper shell 5 of the pre-expander can be removed. At this time, it is convenient to clean the inside of the pre-expander, and it is more convenient to use.

[0048] The above has introduced in detail a fully automatic foam pre-expander provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
