Description

Technical Field

[0001] The utility model relates to the technical field of foam production and processing, and particularly relates to an expanding device for the production of degradable foam protective sleeves. Background Art

[0002] Polystyrene foam plastics are made with polystyrene resin as the main body and adding additives such as foaming agents. It is one of the most widely used cushioning materials. In modern society, the concept of environmental protection is increasing day by day, and degradable foam is widely used. During the production process of degradable foam, it is very important to carry out the expanding work on it.

[0003] After retrieval, an expanding device for the production of degradable foam disclosed in the prior art (Publication No.: CN217073104U) records that "a motor is fixedly installed at the top of the box body, and the bottom of the motor penetrates through the box body and is fixedly installed with a rotating rod. Stirring rods are fixedly installed on both sides of the bottom of the rotating rod, and scraping plates are fixedly installed on both sides of the rotating rod. A clamping seat is fixedly installed on the periphery of the box body, and a plug rod is installed inside the clamping seat. A first protective plate is fixedly installed on the outer side of the plug rod through a buffer pad. Support columns are fixedly installed on both sides of the bottom of the box body, and an elastic clamping ring is installed on the periphery of the support column. A second protective plate is fixedly installed on the outer side of the elastic clamping ring through a buffer pad". Through the combination of various structures, this device can quickly and efficiently carry out the expanding work of foam during the working process, and has good protective safety performance, increasing practicality. However, during actual use, the scraping plate can only clean the inner wall of the box body, but the surface of the auxiliary rod fixedly connected inside the box body cannot be cleaned accordingly, making it easy for materials to remain inside the box body by adhering to the surface of the auxiliary rod, which will not only increase the difficulty of subsequent cleaning but also interfere with the expanding treatment of the next batch. At the same time, the heating tube is fixedly connected to the inside of the box body through the auxiliary rod, resulting in different heating effects on the materials at different positions inside the box body, thereby reducing the expanding efficiency of the device for the materials. And the second protective plate of this device protects the position of the support column, although it can reduce the probability of damage to the support column, however, the overall center of gravity of this device is biased upward in the middle, so the anti-tipping effect is extremely limited.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Referring to Figures 1 to 4As shown in the figure, the utility model provides an inflation device for the production of degradable foam protective covers, including: a box body 1 and a transmission shaft 4. A main motor 3 is fixedly connected to the upper surface of the box body 1. The main motor 3 is connected to the transmission shaft 4 through a coupling, and the transmission shaft 4 is movably connected to the inside of the box body 1 through a sealed bearing. At the same time, the lower surface of the box body 1 is symmetrically connected with columns 17. The outer side surface of the box body 1 is fixedly connected with a support column 15 through a mounting ring 14, and the support column 15 is fixedly connected with the column 17 through a reinforcing plate 16. A heating groove is opened in the middle of the inner side surface of the box body 1, a heating component 11 is fixedly connected in the heating groove, and a heat conduction ring 12 is fixedly connected at the opening of the heating groove. At the same time, a fixing frame 2 is fixedly connected to the top of the inner cavity of the box body 1, and the fixing frame 2 is movably connected to the upper end of the transmission shaft 4 through a sealed bearing. The lower end of the transmission shaft 4 is fixedly connected with a rotating ring 13 through a cross plate 9. The rotating ring 13 is slidably connected to the surface of the heat conduction ring 12, and a cleaning plate 8 is fixedly connected to the inner side surface of the rotating ring 13 through a fixing plate 7. The cleaning plate 8 is slidably connected to the inner side surface of the box body 1. At the same time, one end of the cross plate 9 close to the transmission shaft 4 is fixedly connected with a main stirring plate 5, and the other end of the cross plate 9 is fixedly connected with a secondary stirring plate 6.

[0019] In this embodiment, the materials for producing the degradable foam protective cover are poured into the inside of the box body 1 from the feed port. Then, the switch of the heating component 11 is turned on. The heat generated by the heating component 11 is sequentially transmitted to the rotating ring 13, the fixing plate 7, the cleaning plate 8, the cross plate 9, the secondary stirring plate 6, and the main stirring plate 5 through the heat conduction ring 12 to form multiple heat sources. The switch of the main motor 3 is turned on. The main motor 3 drives the transmission shaft 4 to rotate through the coupling, and the rotating shaft drives the fixedly connected cross plate 9, main stirring plate 5, secondary stirring plate 6, rotating ring 13, fixing plate 7, and cleaning plate 8 to rotate synchronously through the fixing block. Then, these heat sources can not only stir and mix the materials in the box body 1 correspondingly, but also heat and expand the materials correspondingly. Moreover, the rotating heat sources can enhance the uniformity of the materials being heated and shorten the time required for the materials to be completely expanded, thereby improving the inflation efficiency of the materials in the box body 1. At the same time, the expanded materials are also difficult to adhere to the surface of the rotating heat sources. Therefore, the probability of the materials remaining in the box body 1 can be effectively reduced. And the setting of the support column 15 can effectively increase the support range at the lower end of the device, and further effectively reduce the probability of the device tipping over accidentally. The materials after the inflation treatment can be discharged from the discharge port of the box body 1.

And the three cross plates 9 and the fixing block are combined together to form a herringbone distribution.

[0021] In this embodiment, as Figure 1 and Figure 2The setting of the fixed block enables the lower end of the transmission shaft 4 to be stably fixedly connected to the three sets of horizontal plates 9, and then the transmission shaft 4 drives the main stirring plate 5 and the auxiliary stirring plate 6 to rotate synchronously in the box body 1 through the horizontal plates 9, thereby improving the puffing effect of the material in the box body 1.

[0022] As a preferred embodiment, the transverse plate 9 is in a rectangular structure, and two groups of through holes are symmetrically provided on the surface of the transverse plate 9.

[0025] In this embodiment, if Figure 1 and Figure 3 The length of the main stirring plate 5 is greater than that of the auxiliary stirring plate 6, so the main stirring plate 5 can perform corresponding stirring treatment on the material at the bottom of the box body 1 near the discharge port. At the same time, the grooved arc surfaces on both sides of the main stirring plate 5 and the auxiliary stirring plate 6 can enhance the stirring effect of the main stirring plate 5 and the auxiliary stirring plate 6 on the material.

[0026] As a preferred embodiment, the rotating ring 13 has a circular ring structure, the outer diameter of the rotating ring 13 is adapted to the size of the inner side surface of the housing 1, and the heat-conducting ring 12 slidably connected to the rotating ring 13 has a circular ring structure, and the ring widths of the rotating ring 13 and the heat-conducting ring 12 are equal. At the same time, the upper surface of the rotating ring 13 is fixedly connected to the auxiliary ring 10, and the axial section of the auxiliary ring 10 is a right-angled triangle structure.

[0027] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The sizes of the rotating ring 13 and the inner side of the box body 1 are matched, which can not only enhance the stability of the rotating ring 13 and the transmission shaft 4 during rotation, but also enhance the fitting effect between the rotating ring 13 and the inner side of the box body 1. At the same time, the setting of the auxiliary ring 10 can effectively reduce the probability of material remaining on the upper surface of the rotating ring 13.

[0028] As a preferred embodiment, three groups of fixed plates 7 are fixedly connected at equal intervals along the circumferential direction on the inner side surface of the rotating ring 13.

At the same time, the cross-sections of the two cleaning plates 8 are both in an isosceles trapezoid structure.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 4 , the structural setting of the cleaning plate 8 can not only enhance the cleaning effect of the cleaning plate 8 on the inner side surface of the box body 1, but also enhance the structural strength at the connection between the cleaning plate 8 and the fixed plate 7, reducing the probability of accidental fracture at the connection between the cleaning plate 8 and the fixed plate 7.

[0030] As a preferred embodiment, the mounting ring 14 fixedly connected to the outer side surface of the box body 1 is in a circular ring structure.

At the same time, one support column 15 is fixedly connected to two adjacent upright columns 17 through a reinforcing plate 16, and the reinforcing plate 16 is in a V-shaped structure.

[0031] In this embodiment, as Figure 1 and Figure 2 , the setting of the reinforcing plate 16 enables the support column 15 and the upright column 17 to form a whole, enhancing the structural strength between the upright column 17 and the support column 15, reducing the probability of accidental damage to the support column 15 and the upright column 17. At the same time, it can also effectively enhance the stability of the equipment when placed. Moreover, the distribution position between the support column 15 and the upright column 17 enables the equipment to still be placed stably when a certain upright column 17 or support column 15 is damaged, thereby reducing the probability of the equipment tipping over accidentally.
