Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and in particular to a hot air wrinkle removal machine. Background Technology

[0002] Most shoes, such as athletic shoes, have their uppers and soles glued together. To ensure a strong bond, the adhesive process requires pressing the two parts tightly together. However, this often results in wrinkles or dents on the elastic sole surface, affecting the shoe's appearance. In production, repair is usually achieved by baking the glued product in an oven. The high temperature promotes the expansion and recovery of the deformed areas. However, this method is time-consuming, requires significant energy from the baking equipment, and results in high production costs. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a hot air wrinkle removal machine. By providing slots on both sides and above the two oblique sections of the conveyor belt, hot air can be concentrated and guided to the adhesive areas of the sole and upper, improving the utilization rate of hot air and reducing heat loss. Furthermore, by arranging the air supply and return passages within the same cavity, thermal losses during gas circulation can be reduced, further improving heat utilization and lowering energy consumption and production costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The conveyor belt is connected to a drive device and can run under its drive to transport products placed on it through the feeding channel. Both side walls of the feeding channel are connected to an air supply passage, the other end of which is connected to a fan. The fan inlet is connected to a heating chamber containing a heating device. The heating chamber is connected to a return air passage extending to the lower end of the conveyor belt. The fan guides the hot airflow from the heating chamber into the air supply passage and blows it out from both sides of the conveyor belt to heat the products and cause the wrinkles to expand and be removed. The airflow in the feeding channel flows back into the heating chamber through the return air passage.

[0006] As a further explanation of the above technical solution:

[0007] In the above technical solution, the conveyor belt is a horizontally arranged chain, the chain is mounted on the frame via two sprockets, and one of the sprockets is connected to the drive device and can rotate under its drive.

The two side plates are arranged in parallel and vertically mounted on both sides of the sprocket and have a number of second holes and slots evenly spaced along their extension direction. Each second hole and slot is connected to the air supply passage.

[0009] In the above technical solution, each side plate has a protrusion extending obliquely upward toward the inside of the feeding channel above a plurality of second holes and slots. Each protrusion extends in the same direction as the side plate and has a plurality of third holes and slots arranged at equal intervals at its end toward the conveyor belt. Each third hole and slot is connected to the air supply passage.

[0010] In the above technical solution, the air supply passage includes a cavity, one end of which is provided with an air inlet connected to the fan, and the other end of which is provided with a centrally recessed upper sealing plate.

[0011] In the above technical solution, the return air passage is placed inside the cavity, with one open end installed on the bottom plate and the other opening located on the side wall of the heating box and connected to the air inlet of the fan.

[0012] In the above technical solution, the frame is provided with two or more feeding channels arranged in the X direction and passing through the frame in the Y direction. Each feeding channel is provided with a conveyor belt. Several conveyor belts are installed in parallel between two gear shafts. One gear shaft is connected to the drive device through a transmission chain and can rotate under its drive.

[0013] In the above technical solution, each of the feeding channels is provided with two return air passages arranged in the Y direction below, and the two adjacent return air passages arranged in the X direction are both located in the same air supply passage.

[0014] In the above technical solution, the frame is provided with an insulation plate at the top and / or side of each of the feeding channels.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting slots on both sides and above the two oblique sides of the conveyor belt, hot air can be concentrated and guided to the adhesive area of ​​the bottom sole and upper of the shoe, thereby improving the utilization rate of hot air and reducing heat loss; by setting the air supply passage and return passage in the same cavity, the thermal loss of gas during the circulation process can be reduced, further improving the heat utilization rate and reducing energy consumption and production costs.

[0027] like Figure 1-5As shown, the hot air wrinkle removal machine has a feeding channel 20 that runs through the two opposite side walls of the frame 10. A conveyor belt 30 extends in the same direction as the feeding channel 20. The conveyor belt 30 is connected to a drive device 40 and can run under its drive to transport the products placed on it through the feeding channel 20. Both side walls of the feeding channel 20 are connected to an air supply passage 50. The other end of the air supply passage 50 is connected to a fan 60. The air inlet of the fan 60 is connected to a heating box 71. The heating box 71 is equipped with a heating device 80 and is connected to a return air passage 70, which extends to the lower end of the conveyor belt 30. The fan 60 can guide the hot airflow in the heating box 71 into the air supply passage 50 and blow it out from both sides of the conveyor belt 30 to heat the products on it and cause the wrinkles on them to expand and remove wrinkles. The airflow in the feeding channel 20 flows back into the heating box 71 through the return air passage 70. In this embodiment, the frame 10 is provided with two or more feeding channels 20 arranged in the X direction and passing through the frame 10 in the Y direction. Each feeding channel 20 is provided with a conveyor belt 30. Several conveyor belts 30 are installed in parallel between two gear shafts 5. One gear shaft 5 is connected to the drive device 40 through a transmission chain 6 and can rotate under its drive. Below each feeding channel 20, there are two return air passages 70 arranged in the Y direction. The two adjacent return air passages 70 arranged in the X direction are located in the same air supply passage 20. The frame 10 is provided with a heat preservation plate 90 at the upper end and / or side of each feeding channel 20.

[0028] like Figure 2-3 As shown, the conveyor belt 30 is a horizontally arranged chain, which is mounted on the frame 10 via two sprockets 31. One sprocket 31 is connected to the drive device 40 and can rotate under its drive.

[0029] like Figure 4-5 As shown, the feeding channel 20 is formed by a baffle plate 21 and two side plates 22 mounted on the frame 10. The baffle plate 21 is placed horizontally between the chains and has a number of first slots 1 evenly spaced along its extension direction. The two side plates 22 are arranged in parallel and vertically mounted on both sides of the sprocket and have a number of second slots 2 evenly spaced along their extension direction. Each second slot 2 is connected to the air supply passage 50.

[0030] like Figure 6 As shown, each side plate 22 has a protrusion 23 that extends obliquely upward toward the inside of the feeding channel 20 above several second holes 2. Each protrusion 23 extends in the same direction as the side plate 22 and has several third holes 3 arranged at equal intervals at its end toward the conveyor belt 30. Each third hole 3 is connected to the air supply passage 50.

[0031] like Figure 7As shown, the air supply passage 50 includes a cavity 51. One end of the cavity 51 is provided with an air inlet 52, which is connected to the fan 60. The other end of the cavity 51 is provided with a centrally recessed upper sealing plate 53. The feeding channel 20 is located in its recessed area. The two side plates 22 are installed on the two opposite side walls of the recessed area of ​​the upper sealing plate 53. The bottom plate 54 of the recessed area is located below the wind baffle 21 and has several fourth holes 4 arranged at equal intervals along its extension direction.

[0032] like Figure 8 As shown, the return air passage 70 is placed inside the cavity 51, with one open end mounted on the base plate 54 and the other open end located on the side wall of the heating box 71 and connected to the air inlet of the fan 60.

[0033] During operation, the drive unit 40 drives the conveyor belt 30 to move the pasted shoes placed on it forward. Outside air enters the heating box 71 through the return flow path 70 and is heated by the heating device 80. The hot air is guided by the fan 60 into the air supply passage 50. The hot air passes through the cavity 51 and the upper sealing plate 53 and blows hot air towards the shoes from both sides and the upper sides through the second and third slots 3, causing the wrinkles on the shoes to expand and achieve the purpose of wrinkle removal. The airflow in the feeding channel 20 enters the return air channel 70 through the first slot 1 and the fourth slot 4 and is heated again before being introduced into the air inlet channel 50 for recycling.

[0034] This invention improves the utilization rate of hot air and reduces heat loss by setting slots on both sides and above the two oblique sides of the conveyor belt 30. By setting the air supply passage 50 and the return air passage 70 in the same cavity 51, the thermal loss of gas during the circulation process can be reduced, further improving the heat utilization rate and reducing energy consumption and production costs.

[0035] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
