Description

Technical Field

[0001] This utility model relates to the field of feather processing technology, and in particular to a drying device for feather processing. Background Technology

[0002] Feathers are a natural protein material. Due to their high loft, good warmth retention, and light weight, feathers are commonly used to make down jackets, down comforters, and other household items. Currently, after cleaning and washing, feathers are dehydrated using a centrifuge. After dehydration, they need to be dried before being used as insulating filling material.

[0003] When existing feather drying equipment is used, the lack of an effective turning structure leads to uneven drying, where some feathers become over-dried and brittle while others remain incompletely dried. This uneven drying significantly affects the drying quality of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for processing feathers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drying device for processing feathers includes a drying box with support frames welded to the lower outer walls on both sides, a hot air drying mechanism, and an electric discharge mechanism. The top of the drying box is fixedly connected to a feeding hopper, and an L-shaped support is welded to the top outer wall of the feeding hopper.

[0007] The hot air drying mechanism includes a hollow shaft that is vertically rotatably mounted on an L-shaped support, spiral stirring blades welded to the hollow shaft and located inside the drying chamber, a fan support welded to the side wall of the L-shaped support, a hot air fan fixed to the top outer wall of the fan support by bolts, and a rotary drive assembly located at the L-shaped support.

[0008] The rotary drive assembly includes a drive motor fixedly mounted on the top outer wall of the L-shaped support, a drive gear fixedly mounted on the output shaft of the drive motor, and a transmission gear fixedly mounted on the upper part of the hollow shaft.

[0009] Preferably, the output shaft of the drive motor passes through the top of the L-shaped support, and the drive gear meshes with the transmission gear.

[0010] Preferably, the bottom end of the hollow shaft passes through the feed hopper and extends to the lower region of the drying chamber, and the surface of the hollow shaft is provided with uniformly distributed diffusion holes, all of which are located inside the drying chamber.

[0011] Preferably, the outer wall of the hollow shaft is welded with spiral feeding blades located in the feed hopper discharge port area.

[0012] Preferably, the outlet end of the hot air blower is fixedly connected to a hot air pipe, a rotary joint is provided above the hollow shaft, the top end of the hot air pipe is sealed and fixedly connected to the fixed part of the rotary joint, and the top end of the hollow shaft is sealed and fixedly connected to the rotating part of the rotary joint.

[0013] Preferably, the bottom of the drying chamber is provided with a discharge port, and the electric discharge mechanism includes two shafts rotatably installed in the discharge port, two baffles fixedly mounted on the two shafts in sequence, two worm gears fixedly mounted on the outer ends of the two shafts in sequence, and a driver located outside the drying chamber.

[0014] Preferably, the driver includes a support base fixedly connected to the lower outer wall of the rear of the drying chamber, a transmission shaft rotatably installed in the support base, two worm gears sequentially fixedly mounted on the transmission shaft, a motor mounting plate welded to the lower outer wall of the drying chamber, and a servo motor fixed to the side wall of the motor mounting plate by bolts. The two worm gears mesh with two worm wheels respectively, and the helical directions of the two worm gears are opposite.

[0015] Preferably, the output shaft of the servo motor passes through the motor mounting plate and is coaxially and fixedly connected to one end of the transmission shaft via a coupling.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. In the process of hot air conveying, this utility model uses a hot air blower to send hot air from the hot air pipe into the hollow shaft. Then, through the diffusion holes evenly distributed on the surface of the hollow shaft, the hot air flowing into the hollow shaft can be evenly diffused into the drying chamber. Furthermore, through the rotation effect of the spiral stirring blades on the hollow shaft, the feathers entering the drying chamber can be stirred up. This allows them to come into even and sufficient contact with the evenly diffused hot air, facilitating uniform drying treatment. This solves the problem of uneven drying that exists in traditional drying equipment and ensures the drying quality of the drying equipment.

[0018] 2. In the feeding stage, the rotation of the spiral feeding blades can push the feathers accumulated in the feeding hopper discharge area downwards, thereby effectively reducing the clogging of the feeding hopper and helping to speed up the material discharge rate in the feeding hopper. In the discharge stage, the electric discharge mechanism can automatically open the two baffles for rapid discharge, effectively improving the discharge rate of the drying equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1, referring to Figure 1-4 A drying device for processing feathers includes a drying box 1 with support frames welded to the lower outer walls on both sides and a hot air drying mechanism. The top of the drying box 1 is fixedly connected to a feed hopper 2, and an L-shaped support 3 is welded to the top outer wall of the feed hopper 2.

[0028] Specifically, the hot air drying mechanism includes a hollow shaft 4 that is vertically rotatably mounted on an L-shaped support 3, a spiral stirring blade 5 welded to the hollow shaft 4 and located inside the drying chamber 1, a fan support 6 welded to the side wall of the L-shaped support 3, a hot air fan 7 that is fixed to the top outer wall of the fan support 6 by bolts, and a rotary drive assembly located at the L-shaped support 3.

[0029] Furthermore, the rotary drive assembly includes a drive motor 8 fixedly mounted on the top outer wall of the L-shaped support 3, a drive gear 9 fixedly mounted on the output shaft of the drive motor 8, and a transmission gear 10 fixedly mounted on the upper part of the hollow shaft 4. The output shaft of the drive motor 8 passes through the top of the L-shaped support 3, and the drive gear 9 and the transmission gear 10 mesh with each other. Thus, the drive motor 8 controls the drive gear 9 to rotate, and the transmission gear 10 meshing with the drive gear 9 will drive the spiral stirring blades 5 on the hollow shaft 4 to rotate, thereby stirring the feathers entering the drying oven 1.

[0030] Furthermore, the bottom end of the hollow shaft 4 passes through the feed hopper 2 and extends to the lower area of ​​the drying chamber 1. The surface of the hollow shaft 4 is provided with evenly distributed diffusion holes 13. All the diffusion holes 13 are located inside the drying chamber 1. Through the evenly distributed diffusion holes 13, the hot air flowing into the hollow shaft 4 can be evenly diffused into the drying chamber 1.

[0031] Furthermore, a spiral feeding blade 14 located in the discharge port area of ​​the feed hopper 2 is welded to the outer wall of the hollow shaft 4. The spiral feeding blade 14 is driven to rotate by the hollow shaft 4, which can push the feathers accumulated in the discharge port area of ​​the feed hopper 2 downward, thereby effectively reducing the blockage of the feed hopper 2 and helping to speed up the discharge rate of the material in the feed hopper 2.

[0032] Furthermore, the outlet end of the hot air blower 7 is fixedly connected to a hot air pipe 11, and a rotary joint 12 is provided above the hollow shaft 4. The top end of the hot air pipe 11 is sealed and fixedly connected to the fixed part of the rotary joint 12, and the top end of the hollow shaft 4 is sealed and fixedly connected to the rotating part of the rotary joint 12. Through the switching effect of the rotary joint 12, it can be ensured that the hot air blower 7 can smoothly deliver hot air to the hollow shaft 4 in the rotating state.

[0033] Example 2, refer to Figure 5-6 This embodiment is an optimization based on embodiment 1. Specifically, it is a drying device for processing feather pieces, which also includes an electric discharge mechanism, and the bottom of the drying box 1 is provided with a discharge port.

[0034] Specifically, the electric discharge mechanism includes two shafts 15 rotatably installed inside the discharge port, two baffles 16 sequentially fixedly mounted on the two shafts 15, two worm gears 17 sequentially fixedly mounted on the outer ends of the two shafts 15, and a driver located outside the drying oven 1.

[0035] Furthermore, the driver includes a support base 18 fixedly connected to the lower outer wall of the rear of the drying chamber 1, a drive shaft 19 rotatably mounted in the support base 18, two worm gears 20 fixedly mounted on the drive shaft 19 in sequence, a motor mounting plate 21 welded to the lower outer wall of the drying chamber 1, and a servo motor 22 fixed to the side wall of the motor mounting plate 21 by bolts.

[0036] Furthermore, the two worm gears 20 mesh with the two worm wheels 17 respectively, and the helical directions of the two worm gears 20 are opposite. The output shaft of the servo motor 22 passes through the motor mounting plate 21 and is coaxially and fixedly connected to one end of the transmission shaft 19 through a coupling.

[0037] In this embodiment, the servo motor 22 drives the transmission shaft 19 to rotate forward, and then the two worm gears 20 with opposite helical directions on the transmission shaft 19 will rotate accordingly. Subsequently, the two worm wheels 17 meshing with the two worm gears 20 will drive the two baffle plates 16 on the two shafts 15 to rotate in the opposite direction. In this way, the two baffle plates 16 can be automatically opened for rapid material discharge, which effectively improves the discharge rate of the drying equipment. After the material discharge is completed, the two baffle plates 16 can be automatically closed by driving the transmission shaft 19 to reverse by the servo motor 22.

[0038] The working principle of the drying equipment for processing feather pieces is as follows: First, the feather pieces to be dried are poured into the feed hopper 2. Then, the drive motor 8 controls the drive gear 9 to rotate. Subsequently, the transmission gear 10 meshing with the drive gear 9 will drive the spiral stirring blade 5 on the hollow shaft 4 to rotate and the spiral feeding blade 14 to rotate.

[0039] Secondly, the rotation of the spiral feeding blades 14 can push the feathers accumulated in the feed hopper 2 discharge area downward, thereby effectively reducing the blockage of the feed hopper 2 and helping to speed up the discharge rate of the material in the feed hopper 2.

[0040] Finally, hot air is sent from the hot air pipe 11 into the hollow shaft 4 by the hot air blower 7. Then, through the diffuser holes 13 evenly distributed on the surface of the hollow shaft 4, the hot air flowing into the hollow shaft 4 can be evenly diffused into the drying chamber 1 to dry the feathers entering the drying chamber 1. The rotation of the spiral stirring blades 5 can agitate the feathers entering the drying chamber 1, so that the feathers in the drying chamber 1 can be evenly dried by the hot air under agitation.
