Description

A supercritical foaming shoe material heat drying box Technical Field

[0001] This utility model relates to the technical field of shoe material processing equipment, and in particular to a hot drying box for supercritical foamed shoe materials. Background Technology

[0002] With the development of the footwear industry, supercritical foamed footwear materials have attracted widespread attention due to their superior performance. In the production process of supercritical foamed footwear materials, the hot drying chamber is one of the key pieces of equipment. Its function is to heat-treat the footwear material blanks before foaming to meet the requirements of the supercritical foaming process.

[0003] Currently, existing hot drying chambers have some problems in practical use. On the one hand, traditional hot drying chambers lack heat recovery and utilization, increasing energy consumption. On the other hand, shoe materials need to be placed on racks by workers first, and then the racks need to be put into the hot drying chamber, resulting in low automation and inconvenience in handling. Therefore, a supercritical foaming shoe material hot drying chamber is proposed to address the above problems. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A supercritical foamed shoe material drying chamber includes a chamber body, a waste heat recovery mechanism located on the right side of the chamber body, and an automatic transmission mechanism installed inside the bottom of the chamber body. The chamber body adopts a double-layer heat insulation structure, with the inner layer being high-temperature resistant stainless steel and the outer layer being polyurethane material with good heat insulation performance, forming a heat insulation sandwich layer between the two layers. An openable chamber cover is provided on the front side of the chamber body. Electromagnetic induction heating coils are evenly distributed on the inner wall of the chamber body, and temperature sensors are evenly distributed at different positions inside the chamber body. The automatic transmission mechanism includes a threaded rod fixed inside the bottom of the chamber body. One end of the threaded rod is connected to the inside of the rear wall of the chamber body, and the other end is connected to the inside of the front plate. The front plate is fixed inside the front end of the chamber body. The rear end of the threaded rod is connected to the motor output end through a coupling. The side of the threaded rod is threadedly connected to the inner side wall of the threaded hole at the rear half of the movable base plate. A through groove is provided inside the front half of the movable base plate, and the inner side wall of the through groove is fitted to the side of the front plate. A shoe material placement rack is installed on the top of the front half of the movable base plate.

[0006] Preferably, the top of both ends of the movable base plate is welded to the bottom of the side plate, the top of the middle of the movable base plate is vertically connected to the bottom of the rear plate, and the front side of the rear plate is fitted and connected to the rear side of the bottom of the shoe material placement rack.

[0007] Preferably, the waste heat recovery mechanism includes a waste heat recovery box fixed on the right side of the box body. The top front end of the waste heat recovery box is connected to the inside of the box body through an internal air outlet pipe. An exhaust pipe is provided at the bottom rear end of the waste heat recovery box. The exhaust pipe is connected to the internal air outlet pipe through a U-shaped pipe. The top rear end of the waste heat recovery box is connected to the bottom of the air inlet pipe. The gas entering through the air inlet pipe enters the box body through the external air inlet pipe at the bottom front end of the waste heat recovery box.

[0008] Preferably, a first control valve is provided inside the middle of the internal air outlet pipe, a second control valve is provided inside the middle of the external air inlet pipe, and a second temperature sensor is provided inside the waste heat recovery box.

[0009] Preferably, a filter screen is installed at the air inlet of the air intake pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) As the heating process proceeds, the temperature inside the box rises. When it reaches a certain level, the first control valve is opened, and hot air enters the waste heat recovery box through the internal air outlet pipe. The hot air exchanges heat with the cold air entering through the air inlet pipe in the waste heat recovery box. The cold air is preheated, and the preheated air re-enters the box through the external air inlet pipe under the control of the second control valve, thereby realizing the recovery and utilization of heat and reducing energy consumption.

[0011] (2) Open the box cover, the motor reverses and drives the threaded rod to rotate in the opposite direction. The movable base plate moves forward along the threaded rod, bringing the shoe material rack and the heated shoe material blanks out of the box. This makes it easier for staff to take out the shoe materials from the box and also makes it easier to put the shoe materials that need to be heated next time into the box, increasing the convenience of using the device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please refer to Figures 1-5. One embodiment of this utility model provides a supercritical foaming shoe material drying chamber, comprising a chamber body 1, a waste heat recovery mechanism 2 located on the right side of the chamber body 1, and an automatic transmission mechanism 4 installed inside the bottom of the chamber body 1. The chamber body 1 adopts a double-layer heat insulation structure, with the inner layer being high-temperature resistant stainless steel and the outer layer being polyurethane material with good heat insulation performance, forming a heat insulation sandwich layer between the two layers. An openable chamber cover 3 is provided on the front side of the chamber body 1. Electromagnetic induction heating coils 13 are evenly distributed on the inner wall of the chamber body 1, and temperature sensors 14 are evenly distributed within the chamber body. At different locations, the automatic transmission mechanism 4 includes a threaded rod 11 fixed inside the bottom end of the housing 1. One end of the threaded rod 11 is connected to the inside of the rear wall of the housing 1, and the other end is connected to the inside of the front plate 12. The front plate 12 is fixed inside the front end of the housing 1. The rear end of the threaded rod 11 is connected to the motor output end through a coupling. The side of the threaded rod 11 is connected to the inner side wall of the threaded hole at the rear half of the movable base plate 41 through a thread. The front half of the movable base plate 41 is provided with a through groove 44. The inner side wall of the through groove 44 is fitted and connected to the side of the front plate 12. The top of the front half of the movable base plate 41 is equipped with a shoe material placement rack 5.

[0022] The top of both ends of the movable base plate 41 is welded to the bottom of the side plate 43, the top of the middle of the movable base plate 41 is vertically connected to the bottom of the rear plate 42, and the front side of the rear plate 42 is attached to the rear side of the bottom of the shoe material placement rack 5.

[0023] The waste heat recovery mechanism 2 includes a waste heat recovery box 21 fixed on the right side of the box 1. The top front end of the waste heat recovery box 21 is connected to the inside of the box 1 through an internal air outlet pipe 22. An exhaust pipe 25 is provided at the bottom rear end of the waste heat recovery box 21. The exhaust pipe 25 is connected to the internal air outlet pipe 22 through a U-shaped pipe 24. The top rear end of the waste heat recovery box 21 is connected to the bottom of an air inlet pipe 26. The gas entering through the air inlet pipe 26 enters the box 1 through an external air inlet pipe 28 at the bottom front end of the waste heat recovery box 21.

[0024] The internal air outlet pipe 22 is equipped with a first control valve 23 in the middle, the external air inlet pipe 28 is equipped with a second control valve 29 in the middle, the waste heat recovery box 21 is equipped with a second temperature sensor 210, and the air inlet of the air inlet pipe 26 is equipped with a filter screen 27, which can filter the air entering from the outside.

[0025] The supercritical foamed shoe material blank to be heated is placed on the shoe material placement rack 5. The motor is started, and the motor drives the threaded rod 11 to rotate. Since the threaded rod 11 is connected to the threaded hole at the rear half of the movable base plate 41 by a thread, and the through groove 44 at the front half of the movable base plate 41 is attached to the side of the front plate 12, the rotation of the movable base plate 41 is restricted. Therefore, the movable base plate 41 will slowly move backward along the axial direction under the drive of the threaded rod 11, and the shoe material placement rack 5 moves accordingly, gradually feeding the shoe material blank into the box 1. At the same time, the power supply of the electromagnetic induction heating coil 13 is turned on, and the electromagnetic induction heating coil starts to work, causing the shoe material blank to generate heat itself, achieving rapid and uniform heating. The temperature sensor 14 monitors the temperature at different locations inside the box in real time.

[0026] As the heating process proceeds, the temperature inside the chamber 1 rises. Once a certain temperature is reached, the first control valve 23 is opened, and hot air enters the waste heat recovery chamber 21 through the internal air outlet pipe 22. Inside the waste heat recovery chamber 21, the hot air exchanges heat with cold air entering through the air inlet pipe 26, preheating the cold air. The preheated air then re-enters the chamber 1 through the external air inlet pipe 28 under the control of the second control valve 29, thus achieving heat recovery and reducing energy consumption. The second temperature sensor 210 monitors the temperature inside the waste heat recovery chamber 21 in real time, providing data to the control system to rationally adjust the opening degrees of the first control valve 23 and the second control valve 29, optimizing the waste heat recovery effect.

[0027] After the shoe material blanks have completed the heating process in the box 1, the box cover 3 is opened, the motor reverses, and the threaded rod 11 rotates in the opposite direction. The movable base plate 41 moves forward along the threaded rod 11, bringing the shoe material placement rack 5 and the heated shoe material blanks out of the box 1. This makes it easier for workers to take out the shoe materials from the box 1, and also makes it easier to put the shoe materials that need to be heated next time into the box 1, increasing the convenience of using the device.
