Description

Technical Field

[0001] This invention relates to the field of shoemaking equipment, and in particular to a conveying device for drying shoe glue. Background Technology

[0002] During shoe manufacturing, after the upper and sole are bonded together, the adhesive needs to be dried to quickly set the shoe's shape, making the upper and sole more firmly bonded. A drying device, such as the one disclosed in Chinese Utility Model Patent Publication No. CN208573133U, includes a frame, a racetrack-shaped conveyor chain mounted on the frame, and a shoe rack mounted on the conveyor chain. The frame is sequentially equipped with a pre-drying chamber, a vulcanizing chamber, a first vacuum device, a cooling chamber, a second vacuum device, and several post-drying chambers along the conveying direction of the conveyor chain. The cooling chamber is located on the outside of an arc-shaped transition section at one end of the conveyor chain. The arc-shaped transition section at the other end of the conveyor chain in the shoe production line is the pre-gluing area, and the area between the pre-drying chamber and the vulcanizing chamber is the shoe-lifting area. The cooling mechanism for the shoes after drying is mainly a fan, but the fan is in a fixed position. The glue distribution path between the upper and the sole is not regular. Therefore, the fixed fan cannot quickly cool the glue layer between the upper and the sole, and the effect of cooling and shaping the glue layer is not ideal. Summary of the Invention

[0003] The purpose of this invention is to provide a conveying device for drying shoe adhesive. This invention utilizes multi-angle rotating cooling nozzles to cool the adhesive layer between the shoe upper and sole from multiple directions, helping the adhesive layer to cool and set better, thus improving the bonding strength of the shoe adhesive.

[0004] The technical solution provided by this invention is as follows: a conveying device for drying shoe glue includes a ring support, on which a drying box is mounted; a motor support is located at the center of the drying box, and a conveying motor is mounted on the motor support. The extended end of the conveying motor is connected to a rotating frame via a reduction mechanism. Multiple shoe racks are evenly arranged at the outer end of the rotating frame, and the shoe racks are movable within the drying box; a vertical frame is located at the outlet end of the drying box, and a cooling component support is located on the lower side of the flat plate of the vertical frame. A deflection power component is located on one side of the cooling component support, and a deflection frame connected to the output end of the deflection power component is located at the end of the cooling component support. A fixed frame is located on one side of the deflection frame, and a rotary motor is mounted on the fixed frame. A drive pulley is located at the extended end of the rotary motor. A rotating frame is slidably mounted inside the deflection frame, and a driven part connected to the drive pulley via belt drive is located on the outer side of the rotating frame. Multiple vertical frames are evenly arranged on the inner side of the rotating frame, and cooling nozzles are located at the ends of the vertical frames.

[0005] In the aforementioned conveying equipment for drying shoe glue, the rotating frame includes a central shaft column connected to a reduction mechanism, and a plurality of shoe rack support rods are evenly arranged around the central shaft column. A roller track is provided on the outside of the conveying motor, and rollers that fit into the roller track are provided on the lower side of the shoe rack support rods. The shoe rack is located at the end of the shoe rack support rods.

[0006] In the aforementioned conveying equipment for drying shoe glue, the shoe rack includes an outer frame, and shoe support rods are symmetrically arranged inside the outer frame, with the ends of the shoe support rods having an upward inclined structure.

[0007] In the aforementioned conveying equipment for drying shoe glue, the bottom of the inlet and outlet ends of the drying box is provided with sealing cylinders, and the extended end of the sealing cylinders is provided with baffles.

[0008] In the aforementioned conveying equipment for drying shoe glue, the deflection power component includes a deflection motor mounted on the upper end of the cooling component support, with a first pulley at the extended end of the deflection motor; the two ends of the deflection frame are provided with shafts, which are connected to the cooling component support via bearings, and a second pulley is provided at the end of one side of the shaft, with a belt between the first pulley and the second pulley.

[0009] In the aforementioned conveying equipment for drying shoe glue, the rotating frame includes two rings with a middle block between them. An adjustment groove is provided in the vertical frame, and a fixing nail passes through the adjustment groove and is connected to the middle block.

[0010] In the aforementioned conveying equipment for drying shoe glue, the outer side of the lower end of the ring body is connected to the deflection frame via a stepped structure.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the shoes are first placed on a shoe rack, the conveyor motor is started, and the rotating frame is driven to rotate, bringing the shoes into the drying chamber. The rotating frame rotates slowly, and the hot airflow in the drying chamber dries the adhesive layer between the shoe upper and the sole. After the shoes are dried, the shoe rack moves out of the drying chamber and reaches the cooling component support. The deflection power component is activated, causing the deflection frame to swing back and forth at a certain angle. At this time, the cooling nozzles blow cold air onto the shoes. The rotating motor is started, driving the drive pulley to rotate. The drive pulley drives the rotating frame to rotate back and forth, and the position of the cooling nozzles changes in multiple directions. By changing the position of the cooling nozzles, the shoe adhesive is cooled from multiple directions, which helps the adhesive layer to cool and set better, and improves the adhesion of the shoe adhesive.

[0012] 2. Multiple shoe racks are transported by a rotating frame structure. Compared with the linear conveying method, the rotating conveying method can reduce the floor space and output power to multiple shoe racks through the same rotating shaft, ensuring that each shoe rack rotates and is transported at the same time.

[0013] 3. In the shoe rack, two shoe support rods are inserted into the shoe to firmly support it and ensure the stability of the shoe during drying. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example: A conveyor for drying shoe glue, including a ring support 1, as shown in the attached diagram. Figure 1 As shown, a drying chamber 2 is mounted on a ring-shaped support 1. An air pipe is connected to the upper end of the drying chamber, and one end of the air pipe is connected to a hot air blower. The hot airflow generated by the hot air blower enters the drying chamber to dry the shoe glue. A motor support 3 is mounted at the center of the drying chamber 2. A conveyor motor 4 is mounted on the motor support 3. The extended end of the conveyor motor 4 is connected to a rotating frame 5 via a reduction mechanism. Multiple shoe racks 6 are evenly mounted on the outer end of the rotating frame 5. The rotating frame 5 includes a central shaft 51 connected to the reduction mechanism. Multiple shoe rack support rods 52 are evenly fixed around the central shaft 51. A roller track 53 is mounted on the outer side of the conveyor motor 4. Rollers 54 that fit into the roller track 53 are mounted on the lower side of the shoe rack support rods 52. The shoe racks 6 are located at the ends of the shoe rack support rods 52, as shown in the attached diagram. Figure 5As shown, the entire rotating frame rotates as a whole under the drive of the conveyor motor, and multiple shoe racks move simultaneously, maintaining the same distance between them, so that the shoes on the racks can receive the same drying heat; the rollers provide good support, and the multiple shoe racks give the rotating frame a certain weight, allowing it to rotate smoothly; the shoe rack 6 is movably mounted inside the drying chamber 2, which has a slot on its inner side, and one end of the shoe rack support rod is placed in the slot, allowing the shoe rack to rotate inside the drying chamber; the shoe rack 6 includes an outer frame 61, and shoe support rods 62 are symmetrically arranged inside the outer frame 61, as shown in the attached figure. Figure 4 As shown, the end of the shoe support rod 62 is inclined upwards. In the shoe rack, two shoe support rods are inserted into the shoe to firmly support it and ensure its stability during drying. The upward inclination of the shoe support rod ends enhances the stability of the support and prevents the shoe from slipping off. A stand 7 is installed at the outlet end of the drying box 2. A cooling component bracket 8 is installed on the lower side of the flat plate of the stand 7. A deflection power component 9 is installed on one side of the cooling component bracket 8. A deflection frame 10 connected to the output end of the deflection power component 9 is installed at the end of the cooling component bracket 8, as shown in the attached figure. Figure 2 As shown, the deflection power component 9 includes a deflection motor 91 mounted on the upper end of the cooling component bracket 8, with a first pulley 92 installed at the extended end of the deflection motor 91; shafts 93 are mounted at both ends of the deflection frame 10, and the shafts 93 are connected to the cooling component bracket 8 via bearings; a second pulley 94 is mounted at the end of one side of the shaft 93, and a belt 95 is wound between the first pulley 92 and the second pulley 94. The deflection motor drives the first pulley to rotate, and the belt causes the second pulley to rotate, causing the deflection frame to deflect; a fixed frame 11 is provided on one side of the deflection frame 10, and a rotary motor 12 is mounted on the fixed frame 11. The extended end of the rotary motor 12 is connected to a drive pulley 13, as shown in the attached figure. Figure 3 As shown, a rotating frame 14 is slidably installed inside the deflection frame 10. The outer side of the rotating frame 14 has a driven part 15 connected to the driving pulley 13 via belt drive. Multiple vertical frames 16 are evenly installed on the inner side of the rotating frame 14. Cooling nozzles 17 are installed at the ends of the vertical frames 16. The rotating motor also drives the rotating frame via belt drive. One end of the cooling nozzle is connected to a fan via a pipe. The rotating frame rotates back and forth, not around an axis, so the connecting pipes will not become entangled. Sealing cylinders 18 are installed at the bottom of the inlet and outlet ends of the drying chamber 2. A baffle 19 is fixed to the extended end of the sealing cylinder 18. The sealing cylinder drives the baffle to move up and down, sealing the open end of the drying chamber. When the shoe rack is removed, the baffle moves downwards.

[0018] The rotating frame 14 includes two rings 141, with a middle block 142 installed between them. The vertical frame 16 has an adjustment groove 143, through which a fixing pin 144 passes. The fixing pin 144 is connected to the middle block 142. The position of the vertical frame can be adjusted via the adjustment groove, thereby adjusting the height of the cooling nozzles. The position of the cooling nozzles can be flexibly adjusted according to actual cooling requirements. The lower outer side of the rings 141 engages with the deflection frame 10 via a stepped structure. The rotating frame is mounted on the deflection frame through this stepped opening, allowing it to rotate inside the deflection frame.

[0019] The working principle of this invention is as follows: First, the shoes are placed on the shoe rack. The conveyor motor is started, driving the rotating frame to rotate. The shoes are carried into the drying chamber. The rotating frame rotates slowly, and the hot airflow in the drying chamber dries the adhesive layer between the shoe upper and the sole. After the shoes are dried, the shoe rack moves out of the drying chamber and reaches the support of the cooling component. The deflection power component is activated, causing the deflection frame to swing back and forth at a certain angle. At this time, the cooling nozzles blow cold air onto the shoes. The rotating motor is started, driving the drive pulley to rotate. The drive pulley drives the rotating frame to rotate back and forth. The position of the cooling nozzles changes in multiple directions. By changing the position of the cooling nozzles, the shoe adhesive is cooled from multiple directions, which helps the adhesive layer to cool and set better, improving the adhesion of the shoe adhesive.
