Description

Technical Field

[0001] This invention relates to the field of wig manufacturing technology, and in particular to a wig fiber raw material feeding device. Background Technology

[0002] PET is a commonly used raw material in wig manufacturing. PET is a plastic raw material, and polyethylene terephthalate (PET) is the most important type of thermoplastic polyester, often abbreviated as PET or PEIT, and commonly known as polyester resin. It is a condensation polymer of terephthalic acid and ethylene glycol, and together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester. PET is divided into fiber-grade polyester chips and non-fiber-grade polyester chips. ① Fiber-grade polyester is used to manufacture polyester staple fiber and polyester filament, and is the raw material supplied to polyester fiber companies for processing fibers and related products. Polyester is the largest-volume variety of chemical fiber. ② Non-fiber-grade polyester also has applications in bottles, films, etc., and is widely used in packaging, electronics, medical and health, construction, automotive and other fields. Packaging is the largest non-fiber application market for polyester and also the fastest-growing area for PET.

[0003] The production of wigs requires a large amount of raw materials, and the wig fiber production equipment is quite large, making the feeding process extremely inconvenient. Furthermore, once the wig fiber spinning equipment is started, it cannot be stopped and must be kept in a continuously heated state to prevent cooling and blockage of the fiber outlet. To improve production efficiency, continuous feeding is necessary. Most existing wig fiber raw material feeding equipment relies on manual handling or vacuum feeding machines. However, vacuum feeding machines often experience blockage of the material at the suction port, preventing the suction force from completing its function.

[0004] It enables the feeding of wig fiber raw materials and avoids the problem of raw material blockage and accumulation at the adsorption end during negative pressure adsorption feeding, which prevents the adsorption function from being achieved. At the same time, it avoids the raw material from accumulating and blocking in the discharge pipe and being unable to be discharged. The reverse rotation of the drive mechanism drives the stirring fan blades to reverse, which can slow down the discharge of raw materials and at the same time prevent the raw materials from falling into the temporary storage box.

[0005] To address this, we provide a wig fiber raw material feeding device that can feed materials while avoiding the problem of raw material blockage and accumulation at the adsorption end during negative pressure adsorption feeding, thus preventing the adsorption function from being achieved. At the same time, it also avoids the problem of raw material accumulation and blockage in the discharge pipe, preventing the material from being discharged. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a wig fiber raw material feeding device.

[0007] The objective of this invention is achieved as follows: a wig fiber raw material feeding device includes a support frame, a storage tank is provided on the support frame, a discharge pipe is provided at the lower end of the storage tank, a temporary storage box is provided at the lower end of the discharge pipe, a discharge pipe is provided at the right end of the storage box, and a suction machine is connected to the rear end of the discharge pipe.

[0008] Furthermore, a connecting cylinder is provided between the storage tank and the discharge pipe. The connecting cylinder is fixedly connected to the storage tank, and the connecting cylinder is rotatably connected to the discharge pipe. A stirring fan blade is provided on the inner wall of the discharge pipe.

[0009] Furthermore, the discharge pipe is rotatable relative to the temporary storage box.

[0010] Furthermore, a drive mechanism is provided on the upper surface of the temporary storage box, which drives the discharge pipe to rotate.

[0011] Furthermore, a guide plate is provided at the bottom of the temporary storage box, and the guide plate has an upper surface that slopes downward to the left.

[0012] Furthermore, an air inlet is provided on the upper right side of the temporary storage box.

[0013] Furthermore, a limiting cylinder is provided between the temporary storage box and the discharge pipe, and the limiting cylinder can move up and down through the upper surface of the temporary storage box.

[0014] In use, the present invention places wig fiber raw material in the storage tank. When feeding is required, the controller controls the suction machine to work, and at the same time controls the drive mechanism to drive the discharge pipe to rotate. When the discharge pipe rotates, it drives the stirring fan blade to rotate, which speeds up the falling of the raw material. That is, the raw material can fall freely downward under its own gravity. The stirring fan blade can accelerate the falling of the raw material. At the same time, the stirring fan blade can prevent the raw material from being blocked in the discharge pipe, which would prevent the raw material from falling.

[0015] As the mixing fan blades drive the raw material down, the rotation of the discharge pipe causes the guide column to rotate within the first annular groove. When the guide column rotates to the position of the connecting groove, it cannot continue to rotate within the first annular groove due to the action of the guide plate. Under the guidance of the guide plate, the guide column enters the connecting groove and moves within it. Under the action of the guide column, the limiting cylinder moves upward until the guide column enters the second annular groove and rotates within it. Through the above steps, the lower end of the limiting cylinder is disengaged from the limiting block, and the raw material falls through the gap between the limiting cylinder and the limiting block.

[0016] The raw materials fall into the temporary storage box. The inclined surface of the guide plate piles the raw materials on the left side of the temporary storage box. The negative pressure of the suction machine causes the raw materials to enter the discharge pipe. The suction machine drives the raw materials to achieve feeding.

[0017] The inclusion of an air inlet prevents the temporary storage box from being a completely enclosed enclosure, facilitating raw material unloading. Simultaneously, when negative pressure is applied to the temporary storage box via the discharge pipe, it prevents insufficient negative pressure from attracting raw materials from the box and storage tank, thus avoiding feeding failures. Furthermore, when raw materials enter the temporary storage box, any gas inside can be expelled through the air inlet, preventing excessive pressure within the box that could hinder unloading.

[0018] When feeding needs to be stopped, the controller controls the drive mechanism to reverse. The drive mechanism drives the limiting post to reverse within the second annular groove. Due to the spring force, the spring drives the limiting cylinder to move downwards. When the limiting post is at the lower end of the connecting groove, it enters the connecting groove due to the downward movement of the limiting cylinder. The limiting post continues to move, driving the limiting cylinder downwards until the limiting post enters the first annular groove. When the limiting post reverses within the first annular groove, since the upper surface of the guide plate is flush with the lower surface of the first annular groove, the limiting post presses against the upper surface of the guide plate, causing the limiting post to rotate downwards. This allows the limiting post to pass through the first annular groove, realizing the movement of the limiting post within the first annular groove. At this time, the limiting post drives the limiting cylinder to move downwards and fit against the limiting block, preventing raw materials from falling into the temporary storage box and causing it to accumulate, which would affect the subsequent negative pressure suction function.

[0019] The limit block can be configured as a vertically movable structure as needed. The limit block can move up and down on the connecting rod. A return spring is provided between the limit block and the connecting rod to prevent the material between the limit cylinder and the limit block from being squeezed when the limit cylinder moves downward, thus avoiding interference with the movement of the equipment due to the restriction of the downward movement of the limit cylinder.

[0020] Beneficial effects: This device can realize the feeding function of wig fiber raw materials, and avoids the problem of raw material blockage and accumulation at the adsorption end during negative pressure adsorption feeding, which prevents the adsorption function from being achieved. At the same time, it avoids the raw material from accumulating and blocking in the discharge pipe and being unable to be discharged. The reverse rotation of the drive mechanism drives the stirring fan blades to reverse, which can slow down the discharge of raw materials and at the same time prevent the raw materials from continuing to fall into the temporary storage box.

[0032] Example 1, such as Figure 1 As shown in Figure 9, the objective of this invention is achieved as follows: a wig fiber raw material feeding device includes a support frame 1, a storage tank 3 is provided on the support frame 1, a discharge pipe 7 is provided at the lower end of the storage tank 3, a temporary storage box 2 is provided at the lower end of the discharge pipe 7, a discharge pipe 4 is provided at the right end of the storage box, and a suction machine 5 is connected to the rear end of the discharge pipe 4. The suction machine 5 is existing technology and will not be described in detail. It is sufficient to achieve negative pressure suction.

[0033] A connecting cylinder 8 is provided between the storage tank 3 and the discharge pipe 7. The connecting cylinder 8 is fixedly connected to the storage tank 3, and the connecting cylinder 8 is rotatably connected to the discharge pipe 7. An agitator blade 23 is provided on the inner wall of the discharge pipe 7. The agitator blade 23 can drive the raw material to flow quickly, while preventing the raw material from causing blockage in the discharge pipe 7. Furthermore, the reverse rotation of the agitator blade 23 can slow down the flow of raw material, facilitating the subsequent blocking of raw material flow to the temporary storage box 2. The discharge pipe 7 is rotatable relative to the temporary storage box 2. A drive mechanism 6 is provided on the upper surface of the temporary storage box 2. The drive mechanism 6 drives the discharge pipe 7 to rotate; the drive mechanism 6 is not restricted to simply rotating the discharge pipe 7.

[0034] A guide plate 14 is installed at the bottom of the temporary storage bin 2, with its upper surface inclined downwards to the left. An air inlet 13 is located on the upper right side of the temporary storage bin 2. A limiting cylinder 12 is installed between the temporary storage bin 2 and the discharge pipe 7, penetrating the upper surface of the temporary storage bin 2 and movable vertically. The inner wall of the limiting cylinder 12 is in contact with the outer side of the discharge pipe 7, allowing it to move up and down along the pipe. A connecting rod 15 is installed inside the temporary storage bin 2, with a limiting block 16 at its upper end, located directly below the limiting cylinder 12.

[0035] The upper end of the limiting block 16 has a conical structure. The conical structure can prevent the raw materials from accumulating on the limiting block 16, and at the same time increase the contact area between the limiting cylinder 12 and the limiting block 16, which is beneficial to the subsequent barrier function for the raw materials entering the temporary storage box 2. The lower part of the inner side of the limiting cylinder 12 has a chamfered structure, and the upper part of the limiting block 16 and the lower chamfered part of the limiting cylinder 12 fit each other.

[0036] The inner side of the limiting cylinder 12 has an annular groove 18 and an annular groove 19. The annular groove 18 is located above the annular groove 19. A connecting groove 21 is provided between the annular groove 18 and the annular groove 19. The connecting groove 21 has an arc-shaped inclined structure, which facilitates the guide column to drive the limiting cylinder to move up and down. The connecting groove 21 connects the annular groove 18 and the annular groove 19. A guide column 17 is provided on the outer side of the discharge pipe 7. The guide column 17 is movably located in the annular groove 18. A limiting ring 20 is fixedly provided at the lower end of the discharge pipe 7. A moving groove is provided in the lower part of the inner side of the limiting cylinder 12. The limiting ring 20 is rotatably located in the moving groove. A fixing ring 9 is rotatably provided on the outer side of the discharge pipe 7. Connecting rods 10 are evenly distributed on the lower surface of the fixing ring 9. The lower end of the connecting rods 10 is fixedly connected to the temporary storage box 2. A spring 11 is provided between the fixing ring 9 and the upper surface of the limiting cylinder 12. The connecting groove 21 is inclinedly set inside the limiting cylinder 12. A rotatable guide plate 22 is set on the left side of the connection between the connecting groove 21 and the annular groove 18. The guide plate 22 is rotatably connected to the inner wall of the limiting cylinder 12. A torsion spring is set between the guide plate 22 and the inner wall of the limiting cylinder 12. The torsion spring rotates the outer end of the guide plate 22 upward, so that the upper end of the guide plate 22 is in contact with the inner upper surface of the annular groove 18. The torsion spring is a prior art and its function is relatively conventional. The connection technology between the guide plate 22 and the limiting cylinder 12 will not be described in detail here. It is sufficient to achieve the above functions. The guide plate 22 can rotate between the positions of the annular groove 18 and the connecting groove 21. The size of the guide plate 22 can be selected as needed, and no technical restrictions are imposed.

[0037] When using this invention, wig fiber raw materials are placed in the storage tank 3. When feeding is required, the controller controls the suction machine 5 to work, and at the same time controls the drive mechanism 6 to drive the discharge pipe 7 to rotate. When the discharge pipe 7 rotates, it drives the stirring blade 23 to rotate, which speeds up the falling of the raw materials. That is, the raw materials can fall freely downwards under their own gravity. The stirring blade 23 can speed up the falling of the raw materials. At the same time, the stirring blade 23 can prevent the raw materials from being blocked in the discharge pipe 7, which would prevent the raw materials from falling.

[0038] As the mixing blades 23 drive the raw material to fall, the rotation of the discharge pipe 7 causes the guide column 17 to rotate within the annular groove 18. When the guide column 17 rotates to the position of the connecting groove 21, it cannot continue to rotate within the annular groove 18 due to the action of the guide plate 22. Under the guidance of the guide plate 22, the guide column 17 enters the connecting groove 21 and moves within it. Under the action of the guide column 17, the limiting cylinder 12 moves upward until the guide column 17 enters the annular groove 19. The guide column 17 rotates within the annular groove 19. Through the above steps, the lower end of the limiting cylinder 12 is disengaged from the limiting block 16, and the raw material falls through the gap between the limiting cylinder 12 and the limiting block 16.

[0039] The raw materials fall into the temporary storage box 2. The inclined surface of the guide plate 14 piles the raw materials on the left side of the temporary storage box 2. The raw materials enter the discharge pipe 4 through the negative pressure of the suction machine 5. The suction machine 5 drives the raw materials to achieve feeding.

[0040] The air inlet 13 prevents the temporary storage tank 2 from being a completely enclosed box, facilitating raw material unloading. Simultaneously, when negative pressure is applied to the temporary storage tank 2 via the discharge pipe 4, it prevents insufficient negative pressure from attracting the raw materials in the temporary storage tank 2 and storage container 3, thus avoiding feeding failure. Furthermore, when raw materials enter the temporary storage tank 2, the gas inside can be discharged through the air inlet 13, preventing excessive pressure within the temporary storage tank 2 from affecting the unloading process.

[0041] When it is necessary to stop feeding, the controller controls the drive mechanism 6 to reverse. The drive mechanism 6 drives the limit post to reverse within the annular groove 19. Due to the elastic force of the spring 11, the spring 11 drives the limit cylinder 12 to move downward. When the limit post is located at the lower end of the connecting groove 21, it is driven by the downward movement of the limit cylinder 12 and enters the connecting groove 21. The limit post continues to move, driving the limit cylinder 12 to move downward until the limit post enters the annular groove 18. When the limit post reverses within the annular groove 18, since the upper surface of the guide plate 22 is flush with the lower surface of the annular groove 18, when the limit post moves in reverse within the annular groove 18, the limit post presses against the upper surface of the guide plate 22, causing the limit post to rotate downward, thus allowing the limit post to pass through the annular groove 18 and realize the movement of the limit post within the annular groove 18. At this time, the limiting column drives the limiting cylinder 12 to move downward and fit with the limiting block 16, so as to prevent the raw material from falling into the temporary storage box 2 and causing the temporary storage box 2 to be full of raw material, which would affect the subsequent negative pressure suction function.

[0042] The limit block 16 can be configured as a vertically movable structure as needed. The limit block 16 can move up and down on the connecting rod 15. A return spring 24 is provided between the limit block 16 and the connecting rod 15. The elastic force of the return spring on the limit block is greater than the squeezing force of the raw material on the limit block, so as to avoid the raw material between the limit cylinder 12 and the limit block 16 being squeezed when the limit cylinder 12 moves downward, and the downward movement of the limit cylinder 12 being restricted, which would cause motion interference of the equipment.
