Description

Technical Field

[0001] This utility model relates to the technical field of EPS foam foaming, and in particular to a vibration-enhanced EPS packaging foam foaming device. Background Technology

[0002] In the production of EPS packaging foam, the foaming process is the core link, and its quality directly determines the performance and quality of the final EPS packaging foam products. Therefore, a vibration-enhanced EPS packaging foam foaming device is particularly needed.

[0003] A novel EPS board foaming machine, authorized by announcement number CN212764389U, includes a stirring and heating mechanism. This mechanism comprises a foaming tank bottom chamber, a heating spiral tube, a central shaft, spiral blades, and stirring blades. The foaming tank bottom chamber is funnel-shaped, with the heating spiral tube fixedly connected to its inner side via a snap-fit ​​connection. A central shaft is located inside the bottom chamber, with blade holders fixedly connected to its sides. Spiral blades are fixedly connected to both ends of the blade holders, and stirring blades are fixedly connected to the outer side of the central shaft. A foaming tank is located at the top of the bottom chamber. The heating spiral tube heats the raw materials, improving foaming efficiency. The interaction between the central shaft, spiral blades, and stirring blades ensures thorough mixing of the raw materials, resulting in more uniform heating and improved foaming efficiency and quality. However, EPS particles are prone to clumping during foaming and easily attracting static electricity onto the stirring blades, leading to uneven mixing and affecting foaming efficiency.

[0004] To address the aforementioned issues, a vibration-enhanced EPS packaging foam foaming device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a vibration-enhanced EPS packaging foam foaming device to solve the problems of the existing vibration-enhanced EPS packaging foam foaming devices mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibration-enhanced EPS packaging foam foaming device, comprising a mounting platform, a vibration mechanism at the bottom of the mounting platform, and a stirring mechanism at the top of the mounting platform;

[0007] The vibration mechanism includes top mounting columns installed on both sides of the bottom of the mounting platform. The bottom of the mounting platform is provided with top columns on both sides. The inner wall of the top mounting column is provided with a slider. The outer side of the top column is fitted with a first spring. The bottom of the slider is provided with a connector. The top of the connector is provided with a circular groove.

[0009] Preferably, the vibration mechanism further includes top columns installed at the four corners of the bottom of the mounting platform. The bottom of the mounting platform is provided with a first drive motor. A second spring is sleeved on the outside of the top column. A support leg is sleeved on the outside of the top column. An eccentric wheel is provided at the connection end of the first drive motor. There are two sets of eccentric wheels. One end of the eccentric wheel is provided with a rotating shaft. A connecting block is provided between the eccentric wheels. The connecting block is rotatably connected to the eccentric wheel.

[0010] Preferably, the top column passes through the inner wall of the slider, and the first spring is disposed on the inner wall of the slider.

[0011] Preferably, the bottom of the top column is frustum-shaped, the diameter of the circular groove is smaller than the diameter of the frustum surface of the top column, and the top of the connecting block is located on the inner wall of the connector.

[0012] Preferably, the second spring is disposed on the inner wall of the support leg, and the support leg is disposed at the four corners of the top of the base.

[0015] Preferably, the stirring blade has a hollow structure, and the surface of the stirring blade has three sets, all of which are coated with an antistatic coating.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This vibration-enhanced EPS packaging foam foaming device is equipped with a vibration mechanism. The first drive motor drives the eccentric wheel to rotate, and the power is transmitted to the connector and slider through the connecting block. In conjunction with the top column, the first spring and other components, the mounting platform vibrates in the up and down direction. With the synergistic action of the top column, the second spring and the support legs, the vibration effect is further aided in buffering and enhanced, making the vibration of the entire mounting platform more stable and uniform. Stable and uniform vibration helps to loosen and mix the foam during the foaming process, and reduces agglomeration during the foaming process.

[0018] In the mixing mechanism, the second drive motor drives the mixing shaft and the hollowed-out mixing blades to rotate. The material can pass through the mixing blade channel, which can effectively promote the exchange of materials at different positions. The anti-static coating on the surface of the mixing shaft and mixing blades can reduce the static electricity generated by friction during the mixing process, reduce the situation where foam is attracted to the mixing blades due to static electricity, and avoid uneven mixing due to foam adsorption, which affects the foaming efficiency.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example

[0027] like Figure 1-3As shown, the system includes a mounting platform 1, a vibration mechanism 2 at the bottom of the mounting platform 1, and a stirring mechanism 3 at the top of the mounting platform 1. The vibration mechanism 2 includes top mounting columns 201 mounted on both sides of the bottom of the mounting platform 1, top columns 202 on both sides of the bottom of the mounting platform 1, a slider 203 on the inner wall of the top mounting column 201, a first spring 204 sleeved on the outer side of the top column 202, a connector 205 at the bottom of the slider 203, and a circular groove 206 at the top of the connector 205. 2 also includes top columns 207 installed at the four corners of the bottom of the mounting platform 1. The bottom of the mounting platform 1 is provided with a first drive motor 208. A second spring 209 is sleeved on the outside of the top column 207. A support leg 210 is sleeved on the outside of the top column 207. An eccentric wheel 211 is provided at the connection end of the first drive motor 208. There are two sets of eccentric wheels 211. One end of the eccentric wheel 211 is provided with a rotating shaft 212. A connecting block 213 is provided between the eccentric wheels 211. The connecting block 213 is rotatably connected to the eccentric wheel 211.

[0028] It should be noted that in this embodiment, the first drive motor 208 is started first, driving the eccentric wheel 211 to rotate. The rotating shaft 212 ensures that the eccentric wheel 211 can rotate stably. The connecting block 213 connects the two sets of eccentric wheels 211 and transmits power. The top of the connecting block 213 is located on the inner wall of the connector 205, so that the force generated by the rotation of the eccentric wheel 211 is transmitted to the connector 205 through the connecting block 213. The connector 205 drives the slider 203 to move up and down inside the top mounting column 201. Because the bottom of the top column 202 is frustum-shaped and the diameter of the circular groove 206 is smaller than the diameter of the frustum surface of the top column 202, the bottom of the top column 202 can have a certain height of movement in the circular groove 206. When the connector 205 drives the slider 203 to move on the inner wall of the top mounting column 201, in this process, the first spring 204 is compressed and stretched, generating elastic potential energy and working together with the power of the eccentric wheel 211 to make the mounting platform 1 vibrate in the up and down direction.

[0029] As the connector 205 and the slider 203 move, the top column 207 moves inside the support leg 210. During this process, the second spring 209 sleeved on the outside of the top column 207 is continuously compressed and stretched, which plays a role in auxiliary buffering and enhancing the vibration effect, making the vibration of the entire mounting platform 1 more stable and uniform.

[0030] like Figure 4 , 5 As shown, the stirring mechanism 3 includes a stirring blade 301 mounted above the mounting platform 1, a stirring shaft 302 passing through the inner wall of the stirring blade 301, an antistatic coating 303 on the surface of the stirring shaft 302, and a second drive motor 304 on the top of the stirring shaft 302.

[0031] It should be noted that, in this embodiment, the antistatic coating 303 on the surface of the stirring shaft 302 and the stirring blade 301 reduces static electricity generated by friction during stirring, thereby reducing the amount of foam adsorbed on the stirring blade 301 due to static electricity. When the second drive motor 304 drives the stirring shaft 302 to rotate the hollowed-out stirring blade 301, the material can pass through these channels, promoting the exchange of materials at different locations.

[0032] like Figure 1 As shown, the top of the mounting platform 1 is provided with a mounting shell 4, the bottom of the mounting platform 1 is provided with a base 5, and the inner wall of the mounting shell 4 is provided with a foaming tank 6, which facilitates fixing the foaming tank 6 on the top of the mounting platform 1.

[0033] It should be noted that in this embodiment, the mounting shell 4 is located on the top of the mounting platform 1, the foaming tank 6 is disposed on the inner wall of the mounting shell 4, the mounting shell 4 provides a stable placement position for the foaming tank 6, and the base 5 is used in the whole device to provide the installation position and support the components.

[0034] Working principle of this utility model:

[0035] Refer to the instruction manual appendix Figure 1-5 First, the first drive motor 208 starts, driving the eccentric wheel 211 to rotate. The rotating shaft 212 ensures that the eccentric wheel 211 can rotate stably. The connecting block 213 connects the two sets of eccentric wheels 211 and transmits power. The top of the connecting block 213 is located on the inner wall of the connector 205, so that the force generated by the rotation of the eccentric wheel 211 is transmitted to the connector 205 through the connecting block 213. The connector 205 drives the slider 203 to move up and down inside the top mounting column 201. Because the bottom of the top column 202 is frustum-shaped and the diameter of the circular groove 206 is smaller than the diameter of the frustum surface of the top column 202, the bottom of the top column 202 can have a certain height of movement in the circular groove 206. When the connector 205 drives the slider 203 to move on the inner wall of the top mounting column 201, the first spring 204 is compressed and stretched during this process, generating elastic potential energy and working together with the power of the eccentric wheel 211 to make the mounting platform 1 vibrate in the up and down direction.

[0036] As the connector 205 and slider 203 move, the top column 207 moves inside the support leg 210. During this process, the second spring 209 sleeved on the outside of the top column 207 is continuously compressed and stretched, which plays a role in auxiliary buffering and enhancing the vibration effect, making the vibration of the entire mounting platform 1 more stable and uniform.

[0037] The antistatic coating 303 on the surface of the stirring shaft 302 and the stirring blade 301 reduces static electricity generated by friction during stirring, thereby reducing the amount of foam adsorbed on the stirring blade 301 due to static electricity. When the second drive motor 304 drives the stirring shaft 302 to rotate the hollowed-out stirring blade 301, the material can pass through these channels, promoting the exchange of materials at different locations.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
