Description

Technical Field

[0001] This utility model relates to the field of foaming preparation technology, specifically to a preparation device for TPEE foamed composite materials. Background Technology

[0002] Thermoplastic polyester elastomers, also known as polyester rubber, are linear block copolymers containing PBT (polybutylene terephthalate) hard segments and aliphatic polyester or polyether soft segments. TPEE combines the excellent elasticity of rubber with the easy processability of thermoplastics, offering adjustable hardness and design flexibility, making it a promising new variety of thermoplastic elastomers.

[0003] Foaming refers to the process of forming a bubble structure inside plastics through physical, chemical, or mechanical methods, commonly seen in the plastics processing industry. In addition, in therapeutics, it also refers to external treatments that induce localized blistering through the application of irritating drugs. When preparing foamed composite materials, multiple raw materials need to be added to the equipment and stirred. While existing stirring and preparation equipment can stir and prepare composite materials, it requires cleaning and routine maintenance after stirring. Most existing mixing and preparation equipment is an integrated structure, making it inconvenient for workers to clean and maintain the stirring paddle, thus greatly reducing the applicability of the preparation equipment.

[0004] Therefore, we propose a preparation apparatus for TPEE foamed composite materials to solve the above problems. Utility Model Content

A sealing cover plate is sealed to the upper end of the preparation chamber and is connected to the preparation chamber by bolts passing through the sealing cover plate; The feed port is connected to the upper end of the sealing cover plate, and a one-way valve is installed inside the sealing cover plate. An inlet and outlet pipe is connected to one side of the upper end face of the sealing cover plate, and a valve assembly is installed in the center of the inlet and outlet pipe.

[0007] Furthermore, the driving mechanism includes a synchronous pulley, a servo motor, and a drive wheel. The synchronous pulley is fixed to the lower end face of the connecting rod, the servo motor is fixed to the upper end face of the base component and located on one side of the preparation chamber, and the drive wheel is fixed to the output end of the servo motor. The drive wheel is connected to the synchronous pulley via a synchronous belt.

[0008] Furthermore, the synchronous wheel and the drive wheel maintain the same horizontal center line, and the diameter of the synchronous wheel is larger than that of the drive wheel.

[0009] Furthermore, the outer surface of the connecting rod is uniformly provided with locking grooves, the cross-section of the locking grooves is a triangular structure, and the connecting sleeve is slidably sleeved on the outer surface of the connecting rod with the internal protrusions embedded in the locking grooves. The center of the sealing cover is provided with a limiting slot, and a bearing is provided inside the limiting slot and contacts the bottom of the connecting rod.

[0010] Furthermore, the stirring assembly includes a first stirring blade and a second stirring blade. The first stirring blade is fixed to the outer surface of the connecting sleeve, and the second stirring blade is disposed inside the first stirring blade.

[0011] Furthermore, the second stirring blade is fixed to the connecting sleeve, and the first stirring blade and the second stirring blade are arranged in a spiral shape and rotate in opposite directions.

[0012] Furthermore, a discharge port is connected to one side of the preparation silo, and a one-way valve is also provided inside the discharge port.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a device for preparing TPEE foamed composite materials, which has the following beneficial effects: This invention utilizes a drive mechanism to rotate the connecting rod, facilitating subsequent mixing of foamed composite materials. Since the drive wheel is larger than the synchronous wheel, the rotation efficiency of the connecting rod is improved, further expanding the applicability of the equipment. The connecting sleeve is connected to the connecting rod via a locking groove, and the top of the connecting rod is restrained and limited by a limiting slot on the inner side of the sealing cover, preventing the connecting sleeve from shifting or shaking. This facilitates subsequent maintenance and cleaning of the connecting sleeve after use.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example like Figure 1-5 As shown, an embodiment of the present invention provides a preparation apparatus for TPEE foamed composite material, comprising a base 1 and a preparation chamber 2 fixed to one side of the upper end face of the base 1, and further comprising: The connecting rod 3 is rotatably connected to the center of the preparation chamber 2, with one end extending into the base 1. The base 1 contains a drive mechanism to rotate the connecting rod 3. The drive mechanism includes a synchronous wheel 4, a servo motor 5, and a drive wheel 6. The synchronous wheel 4 is fixed to the lower end face of the connecting rod 3, the servo motor 5 is fixed to the upper end face of the base 1 and located on one side of the preparation chamber 2, and the drive wheel 6 is fixed to the output end of the servo motor 5. The drive wheel 6 is connected to the synchronous wheel 4 via a synchronous belt. The servo motor 5 drives the drive wheel 6 to rotate, and when the drive wheel 6 rotates, the synchronous belt drives the synchronous wheel 4 to rotate accordingly, facilitating subsequent mixing of the foamed composite material via the connecting rod 3. The synchronous wheel 4 and the drive wheel 6 maintain the same horizontal centerline, and the diameter of the synchronous wheel 4 is larger than that of the drive wheel 6. Because the drive wheel 6 is larger than the synchronous wheel 4, the synchronous wheel 4 can rotate 5 times when the drive wheel 6 rotates 1 revolution, thereby improving the rotation efficiency of the connecting rod 3 and further expanding the applicability of the equipment. A connecting sleeve 7 is fitted onto the outer surface of the connecting rod 3, and stirring components 8 are evenly distributed on the outer surface of the connecting sleeve 7. A sealing cover plate 9 is sealed and connected to the upper end of the preparation chamber 2 by bolts passing through the sealing cover plate 9 and the preparation chamber 2. A locking groove 301 is evenly distributed on the outer surface of the connecting rod 3. The locking groove 301 has a triangular cross-section. The connecting sleeve 7 is slidably fitted onto the outer surface of the connecting rod 3, and the internal protrusions are embedded in the locking groove 301. A limiting slot 10 is opened in the center of the sealing cover plate 9, and a bearing is installed inside the limiting slot 10 and contacts the bottom of the connecting rod 3. The connecting rod 3 can be slidably embedded into the connecting sleeve 7, and the locking groove 301 can ensure the connection effect and prevent the connecting sleeve 7 from shifting or shaking during operation. In addition, the limiting slot 10 on the inner side of the sealing cover plate 9 restricts the top of the connecting rod 3, which can prevent the connecting sleeve 7 from shifting or shaking, thus facilitating the subsequent maintenance and cleaning of the connecting sleeve 7 after use. The stirring assembly 8 includes a first stirring blade 801 and a second stirring blade 802. The first stirring blade 801 is fixed to the outer surface of the connecting sleeve 7, and the second stirring blade 802 is disposed inside the first stirring blade 801. The first stirring blade 801 and the second stirring blade 802 are arranged in a spiral, which can increase the stirring effect of the equipment. The second stirring blade 802 is fixed to the connecting sleeve 7. The first stirring blade 801 and the second stirring blade 802 are arranged in a spiral and rotate in opposite directions. Because the first stirring blade 801 and the second stirring blade 802 have different size ratios and are arranged in a spiral and rotate in opposite directions, the stirring preparation effect of the equipment can be further improved. The feed port 11 is connected to the upper end of the sealing cover plate 9, and a one-way valve is installed inside the sealing cover plate 9. An air inlet and outlet pipe 12 is connected to one side of the upper end face of the sealing cover plate 9, and a valve assembly 13 is installed in the center of the air inlet and outlet pipe 12. A discharge port 14 is connected to one side of the preparation chamber 2, and a one-way valve is also installed inside the discharge port 14. The feed port 11 can be used to replenish the material, and the one-way valve inside can seal the preparation chamber 2 during preparation. The air inlet and outlet pipe 12 can be connected to a high-pressure air pump for easy subsequent gas guidance. After foaming is completed, the valve assembly 13 is opened to slowly discharge the gas in the preparation chamber 2. The pressure in the preparation chamber 2 is observed by a pressure gauge until the pressure in the preparation chamber 2 drops to the same as the external pressure. Then the discharge port 14 is opened to discharge the foamed material through the discharge port 14, avoiding the material from being sprayed out under the action of pressure difference when the discharge port 14 is opened directly.

[0018] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
