Description

Technical Field

[0001] This application relates to the technical field of waste polyester fiber processing, and in particular to a pressing apparatus for near-low temperature molding of waste polyester fibers. Background Technology

[0002] Polyester fiber is a synthetic fiber made from organic diacids and diols through chemical polycondensation; it belongs to the category of polymer compounds.

[0003] A search revealed a Chinese patent publication (CN202021411161.7) for a multi-layer polyester fiber pad hot-pressing bonding device. The device includes a base with four supports vertically mounted above it. A top frame is fixedly mounted above the supports, and a drive motor is located at the center of the top of the top frame. A sleeve is fixedly mounted at the center of the bottom of the top frame, and a telescopic rod is installed inside the sleeve. By incorporating upper and lower heating plates, the upper and lower surfaces of the polyester fiber pad can be heated simultaneously during hot pressing, ensuring uniform heating. A partition prevents the polyester fiber pad from sticking to the heating plates due to the high temperature and pressure during hot pressing, thus preventing damage to the pad. This device offers high safety performance and ensures product quality.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: First, although heating measures are provided during pressing, temperature sensing measures are lacking. This means that the specific temperature on the heating plate cannot be accurately determined during the heating process, affecting the subsequent pressing effect. Second, after pressing is completed, the pressed product needs to be removed and raw materials need to be placed in. During this period, the device needs to be stopped, which is extremely time-consuming and reduces work efficiency. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a pressing apparatus for near-low temperature molding of waste polyester fibers. For example... Figure 1 As shown, the system includes a base plate 1. Vertical rods 12 are fixedly connected to the top of the base plate 1 near its four corners. A top plate 13 is fixedly connected to the top of the four vertical rods 12. A hydraulic cylinder 14 is fixedly installed through the top plate 13. A hollow plate 18 is fixedly installed at the bottom of the hydraulic cylinder 14. A cooling component is provided on the top of the hollow plate 18 to cool and lower the temperature inside the hollow plate 18. A pressing plate 19 is embedded in the bottom of the hollow plate 18, using the low temperature inside the hollow plate 18 to cool the pressing plate 19, facilitating subsequent low-temperature pressing. Two pressing plates 9 are provided at the bottom of the pressing plate 19. The two pressing plates 9 are provided with a moving component at the bottom. The moving component drives the pressing plates 9 to move. The production efficiency is improved by the cyclic movement of the two pressing plates 9. A temperature sensor 20 is installed on the top of the hollow plate 18. The temperature sensor 20 is used to sense the temperature of the hollow plate 18 and the pressing plate 19. A vertical plate 2 is fixedly connected between the two vertical rods 12 on the left side. A controller 3 and two control panels 4 are installed on the left side of the vertical plate 2. The controller 3 and the control panels 4 can be used to control the opening and closing of electrical appliances.

[0024] Please see Figure 5 The refrigeration assembly includes a cooler 21, which is fixedly installed on the top of the hollow plate 18. A refrigeration pipe 23 is inserted and installed on the outside of the cooler 21. The end of the refrigeration pipe 23 away from the cooler 21 passes through the outer wall of the hollow plate 18 and extends into the inner cavity of the hollow plate 18. By using the cooler 21 and the refrigeration pipe 23 to inject cold air into the hollow plate 18, the purpose of cooling the hollow plate 18 is achieved.

[0025] Please see Figure 5The outer wall of the refrigeration pipe 23 has several cold air holes 24, which are evenly distributed. By using the arrangement of multiple evenly distributed cold air holes 24, cold air can be evenly injected into the hollow plate 18, so that the low temperature on the hollow plate 18 and the pressing plate 19 is uniform, thereby improving the effect of low temperature pressing.

[0026] Please see Figure 5 Two ventilation meshes 22 are embedded on the outside of the cooler 21. The ventilation meshes 22 can ensure the ventilation and heat dissipation of the cooler 21 and ensure the service life of the cooler 21.

[0027] Please see Figure 2 The moving component includes a hollow shell 5, which is fixedly installed on the top of the base plate 1. A motor 6 is fixedly connected to the front side of the hollow shell 5, and a screw 7 is fixedly connected to the rear side of the motor 6. The rear end of the screw 7 passes through the hollow shell 5 and is movably connected to the hollow shell 5. Two sets of threaded sleeves 8 are threadedly connected to the outside of the screw 7. A pressing plate 9 is fixedly installed on the top of each of the two threaded sleeves 8. The motor 6 drives the two threaded sleeves 8 on the screw 7 to move, and the two threaded sleeves 8 drive the corresponding pressing plate 9 to move. This cycle can effectively improve production efficiency.

[0028] Please see Figure 2 Two sliders 10 are fixedly connected to the outer sides of the two threaded sleeves 8. Slide grooves 11 are opened on both sides of the inner wall of the hollow shell 5. The sliders 10 are slidably connected to the inner cavity of the corresponding slide grooves 11. By using the cooperation between the sliders 10 and the slide grooves 11, the horizontal movement trajectory of the threaded sleeves 8 is limited, thereby improving the stability of the threaded sleeves 8 and even the pressing plate 9 and other components.

[0029] Please see Figure 3 Four limiting rods 16 are fixedly connected to the top of the hollow plate 18, and four limiting holes 15 are opened on the top plate 13. The top ends of the four limiting rods 16 pass through the corresponding limiting holes 15 and are fixedly connected to the limiting blocks 17. By using the cooperation of the limiting rods 16, the limiting holes 15 and the limiting blocks 17, the vertical movement trajectory of the pressing plate 19 and the hollow plate 18 and other components is limited, thereby improving stability.

[0030] The implementation principle of the pressing device for near-low temperature molding of waste polyester fiber in this application embodiment is as follows: First, waste polyester fiber is added into the two sets of pressing discs 9, and during this period, the cooler 21 is driven. The cooler 21 and the cooler pipe 23 are used to inject cold air into the hollow plate 18 to reduce the temperature of the hollow plate 18 and the pressing plate 19. The temperature sensor 20 is used to sense the temperature in real time and display the temperature information on the control screen 4. The operator can directly obtain the temperature information and adjust it in time according to the pressing temperature requirements. Then, the hydraulic cylinder 14 is driven to push the hollow plate 18 downward. The hollow plate 18 drives the pressing plate 19 to move downward. The lowered pressing plate 19 is used to perform low-temperature pressing of the waste polyester fiber inside the pressing disc 9.

[0031] After pressing is completed, the hydraulic cylinder 14 drives the pressing plate 19 to reset and simultaneously drives the motor 6, causing the motor 6 to drive the screw 7 to rotate. The screw 7 drives the two sets of threaded sleeves 8 to move synchronously. The two threaded sleeves 8 respectively drive the corresponding pressing discs 9 to move. At this time, one pressing disc 9 with the pressed waste polyester fibers moves to the outside, while the other pressing disc 9 with the unpressed waste polyester fibers moves to the pressing station. The above operation is repeated to continue pressing. During pressing, the workers need to take out the pressed waste polyester fibers and add new waste polyester fibers for subsequent processing. This cycle is repeated to improve efficiency.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
