Description

Technical Field

[0001] The invention relates to the technical field of wig production, in particular to a wig fiber raw material feeding device. Background Art

[0002] PET raw materials are mostly used in the production process of wigs. PET is a plastic raw material. Polyethylene terephthalate is the most important variety of thermoplastic polyester, referred to as PET or PEIT, commonly known as polyester resin. It is a condensation product 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 make polyester staple fibers and polyester filaments, and is the raw material for polyester fiber companies to process fibers and related products. Polyester is the largest variety of chemical fibers. ② Non-fiber-grade polyester also has uses such as bottles and films, and is widely used in packaging, electronics, medical and health, construction, automobiles and other fields. Among them, packaging is the largest non-fiber application market for polyester, and it is also the fastest growing field for PET.

[0003] The raw materials required in the wig making process are huge, and the wig fiber production equipment is relatively tall, which is extremely inconvenient in the process of feeding the raw materials. In addition, since the wig fiber spinning equipment cannot stop working once it is turned on, it is necessary to continuously maintain the working heating state to avoid cooling and causing the outlet hole to be blocked. In order to better improve production efficiency, it is necessary to continuously ensure feeding; the existing wig fiber raw material feeding equipment is mostly manually carried and fed or vacuum suction machine is used for feeding. When the vacuum suction machine is feeding, the raw materials are often blocked at the suction port, causing the adsorption force to be unable to complete the suction function.

[0004] The feeding function of the wig fiber raw materials is realized, and the problem of the negative pressure adsorption causing the raw materials to be blocked and accumulated at the adsorption end and the inability to achieve the adsorption function due to the negative pressure adsorption is avoided during the negative pressure adsorption feeding, and the raw materials are prevented from accumulating and blocking in the discharge pipe and being unable to be discharged; the reversal of the driving mechanism drives the reversal of the stirring blades to slow down the discharge of the raw materials on the one hand, and at the same time, the function of preventing the raw materials from continuing to fall into the temporary storage box can be realized.

[0005] To this end, we provide a wig fiber raw material feeding device that can have a feeding function and avoid the problem of negative pressure adsorption causing the raw materials to be blocked and accumulated at the adsorption end and the negative pressure failing to achieve the adsorption function, while also avoiding the accumulation of raw materials in the discharge pipe and clogging the discharge pipe. Summary of the invention

[0006] The present invention aims to overcome the deficiencies in the prior art and provide a wig fiber raw material feeding device.

[0007] The objective of the present invention is achieved as follows: a wig fiber raw material feeding device comprises a support frame, a storage tank is arranged on the support frame, a discharge pipe is arranged at the lower end of the storage tank, a temporary storage box is arranged at the lower end of the discharge pipe, a discharge pipe is arranged 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 tube is provided between the storage tank and the discharge pipe, the connecting tube is fixedly connected to the storage tank, the connecting tube and the discharge pipe are rotatably connected, and 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 driving mechanism is provided on the upper surface of the temporary storage box, and the driving mechanism drives the discharge pipe to rotate.

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

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

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

[0014] When the present invention is used, wig fiber raw materials are placed in a storage tank. When loading is required, the controller controls the suction machine to work, and at the same time controls the driving mechanism to drive the discharge pipe to rotate. When the discharge pipe rotates, the stirring blades are driven to rotate to accelerate the falling of the raw materials. That is, the raw materials can fall downward in a free fall due to their own gravity, and the falling of the raw materials can be accelerated by the driving of the stirring blades. At the same time, the stirring blades can prevent the raw materials from being blocked in the discharge pipe, causing the raw materials to be unable to fall.

[0015] While the stirring blades drive the raw materials to fall, the rotation of the discharge pipe drives the guide column to rotate in the annular groove one. When the guide column rotates to the connecting groove position, it cannot continue to rotate in the annular groove one due to the action of the guide plate. Under the guidance of the guide plate, the guide column enters the connecting groove, and moves in the connecting groove. Under the action of the guide column, the limit cylinder moves upward until the guide column enters the annular groove two, and the guide column rotates in the annular groove two. Through the above steps, the lower end of the limit cylinder is driven to separate from the limit block, and the raw materials fall through the gap between the limit cylinder and the limit block.

[0016] The raw materials fall into the temporary storage box, and are accumulated on the left side of the temporary storage box through the inclined surface of the guide plate. The raw materials enter the discharge pipe through the negative pressure of the suction machine, and the raw materials are driven by the suction machine to realize the loading of the raw materials.

[0017] The provision of an air inlet can prevent the temporary storage box from being a closed box, which can facilitate the unloading of raw materials. At the same time, when the discharge pipe gives negative pressure to the temporary storage box, it can prevent the negative pressure from being insufficient to absorb the raw materials in the temporary storage box and the storage tank, causing the loading failure. When the raw materials enter the temporary storage box, the gas in the temporary storage box can be discharged to the outside through the air inlet, avoiding excessive pressure in the temporary storage box and affecting the unloading.

[0018] When it is necessary to stop unloading, the controller controls the driving mechanism to reverse, and the driving mechanism drives the limit post to reverse in the annular groove 2. Due to the elastic force of the spring, the spring drives the limit cylinder to move downward. When the limit post is located at the lower end of the connecting groove, it is affected by the downward movement of the limit cylinder, and the limit post enters the connecting groove. The limit post continues to move, driving the limit cylinder to move downward until the limit post enters the annular groove 1. When the limit post enters the annular groove 1 and reverses, since the upper surface of the guide plate is flush with the lower surface of the annular groove 1, when the limit post reverses and moves in the annular groove 1, the limit post squeezes the upper surface of the guide plate, so that the limit post rotates downward, and then the limit post passes through the annular groove 1, realizing the movement of the limit post in the annular groove 1. At this time, the limit post drives the limit cylinder to move downward and fit with the limit block, preventing the raw materials from falling into the temporary storage box again, causing the temporary storage box to be full of raw materials, affecting the subsequent negative pressure suction function.

[0019] The limit block can be set as an up and down moving structure as needed. The limit block can move up and down on the connecting rod. A return spring is arranged between the limit block and the connecting rod to prevent the raw material between the limit cylinder and the limit block from being squeezed when the limit cylinder moves downward. The downward movement of the limit cylinder is restricted, causing movement interference of the equipment.

[0020] Beneficial effects: The device can realize the feeding function of wig fiber raw materials, and avoid the problem of negative pressure adsorption causing blockage and accumulation of raw materials at the adsorption end and inability to achieve the adsorption function, while avoiding the accumulation and blockage of raw materials in the discharge pipe and inability to discharge; the reversal of the driving mechanism drives the reversal of the stirring blades to slow down the discharge of raw materials, and at the same time can realize the function of preventing the raw materials from continuing to fall into the temporary storage box.

[0032] Embodiment 1, as Figure 1 —9, the object of the present invention is achieved as follows: a wig fiber raw material feeding device comprises a support frame 1, a storage tank 3 is arranged on the support frame 1, a discharge pipe 7 is arranged at the lower end of the storage tank 3, a temporary storage box 2 is arranged at the lower end of the discharge pipe 7, a discharge pipe 4 is arranged at the right end of the storage box, a suction machine 5 is connected to the rear end of the discharge pipe 4, the suction machine 5 is a prior art and no further technical description is made, and it only needs to realize negative pressure suction.

[0033] A connecting tube 8 is provided between the storage tank 3 and the discharge pipe 7, and the connecting tube 8 is fixedly connected to the storage tank 3, and the connecting tube 8 is rotatably connected to the discharge pipe 7. The inner wall of the discharge pipe 7 is provided with a stirring blade 23, and the stirring blade 23 can drive the raw material to be discharged quickly, and at the same time, it can avoid the raw material from being blocked in the discharge pipe 7, and the reversal of the stirring blade 23 can slow down the discharge of the raw material, and provide convenience for the subsequent blocking of the raw material from being discharged to the temporary storage box 2. The discharge pipe 7 is rotatable relative to the temporary storage box 2. A driving mechanism 6 is provided on the upper surface of the temporary storage box 2, and the driving mechanism 6 drives the discharge pipe 7 to rotate, and the driving mechanism 6 can drive the discharge pipe 7 to rotate without restriction.

[0034] A guide plate 14 is provided at the bottom of the temporary storage box 2, and the guide plate 14 is a structure in which the upper surface is inclined downward to the left. An air inlet 13 is provided at the upper right part of the temporary storage box 2. A limiting cylinder 12 is provided between the temporary storage box 2 and the discharge pipe 7, and the limiting cylinder 12 can move up and down and penetrate the upper surface of the temporary storage box 2. The inner side wall of the limiting cylinder 12 is in contact with the outer side of the discharge pipe 7, and the limiting cylinder 12 can move up and down along the discharge pipe 7. A connecting rod 1015 is provided in the temporary storage box 2, and a limiting block 16 is provided at the upper end of the connecting rod 1015, and the limiting block 16 is located directly below the limiting cylinder 12.

[0035] The upper end of the limit block 16 is a conical structure, which can prevent the raw materials from piling up on the limit block 16 and increase the contact area between the limit cylinder 12 and the limit block 16, which is beneficial to the subsequent blocking function of the raw materials entering the temporary storage box 2; the lower part of the inner side surface of the limit cylinder 12 is a bevel chamfered structure, and the upper part of the limit block 16 and the lower part of the limit cylinder 12 are in line with each other.

[0036] The inner side of the limiting cylinder 12 is provided with an annular groove 18 and an annular groove 2 19, the annular groove 18 is located above the annular groove 2 19, and a connecting groove 21 is provided between the annular groove 18 and the annular groove 2 19, and the connecting groove 21 is an arc-shaped inclined structure, which can facilitate the guide column to drive the limiting cylinder to move up and down. The connecting groove 21 connects the annular groove 18 with the annular groove 2 19; the outer side of the discharge pipe 7 is provided with a guide column 17, and the guide column 17 is movably located in the annular groove 18; the lower end of the discharge pipe 7 is fixedly provided with a limiting ring 20, and the lower part of the inner side of the limiting cylinder 12 is provided with a moving groove, and the limiting ring 20 can move up and down and rotatably is located in the moving groove. The outer side of the discharge pipe 7 is rotatably provided with a fixing ring 9, and the lower surface of the fixing ring 9 is evenly distributed with connecting rods 1015, and the lower end of the connecting rod 1015 is fixedly connected to the temporary storage box 2, and a spring 11 is provided between the fixing ring 9 and the upper surface of the limiting cylinder 12. The connecting groove 21 is obliquely arranged in the limiting cylinder 12, and a rotatable guide plate 22 is arranged on the left side of the connection between the connecting groove 21 and the annular groove 18. The guide plate 22 and the inner wall of the limiting cylinder 12 are rotatably connected, and a torsion spring is arranged 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 fits with the inner upper surface of the annular groove 18. The setting of the torsion spring is the existing technology, and its function is relatively conventional. The connection technology with the guide plate 22 and the limiting cylinder 12 is not described here. It is sufficient to achieve the above-mentioned functions, and the guide plate 22 can be rotated between the position of the annular groove 18 and the connecting groove 21. The size of the guide plate 22 can be selected according to needs, and there is no technical limitation.

[0037] When the present invention is used, the wig fiber raw material is placed in the storage tank 3. When loading is required, the suction machine 5 is controlled by the controller to work, and the driving mechanism 6 is controlled to drive the discharge pipe 7 to rotate. When the discharge pipe 7 rotates, the stirring blades 23 are driven to rotate to accelerate the falling of the raw materials; that is, the raw materials can fall downward in a free fall due to their own gravity, and the falling of the raw materials can be accelerated by the stirring blades 23. At the same time, the stirring blades 23 can prevent the raw materials from being blocked in the discharge pipe 7, causing the raw materials to be unable to fall.

[0038] While the stirring blades 23 drive the raw materials to fall, the rotation of the discharge pipe 7 drives the guide column 17 to rotate in the annular groove 18. When the guide column 17 rotates to the position of the connecting groove 21, it cannot continue to rotate in 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 the guide column 17 moves in the connecting groove 21. Under the action of the guide column 17, the limit cylinder 12 moves upward until the guide column 17 enters the annular groove 2 19, and the guide column 17 rotates in the annular groove 2 19. Through the above steps, the lower end of the limit cylinder 12 is driven to separate from the limit block 16, and the raw material falls through the gap between the limit cylinder 12 and the limit block 16.

[0039] The raw materials fall into the temporary storage box 2, and are accumulated on the left side of the temporary storage box 2 through the inclined surface of the guide plate 14. The raw materials enter the discharge pipe 4 through the negative pressure of the suction machine 5, and the suction machine 5 drives the raw materials to be loaded.

[0040] The provision of the air inlet 13 can prevent the temporary storage box 2 from being a closed box, and can facilitate the unloading of raw materials. At the same time, when the discharge pipe 4 gives negative pressure to the temporary storage box 2, it can prevent the negative pressure from being insufficient to absorb the raw materials in the temporary storage box 2 and the storage tank 3, causing the unloading to fail. When the raw materials enter the temporary storage box 2, the gas in the temporary storage box 2 can be discharged outward through the air inlet 13, avoiding excessive pressure in the temporary storage box 2, which affects the unloading of materials.

[0041] When it is necessary to stop feeding, the controller controls the driving mechanism 6 to reverse, and the driving mechanism 6 drives the limit column to reverse in 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 column is located at the lower end of the connecting groove 21, it is affected by the downward movement of the limit cylinder 12, and the limit column enters the connecting groove 21. The limit column continues to move, driving the limit cylinder 12 to move downward until the limit column enters the annular groove 18. When the limit column enters the annular groove 18 to reverse, since the upper surface of the guide plate 22 is flush with the lower surface of the annular groove 18, when the limit column reverses in the annular groove 18, the limit column squeezes the upper surface of the guide plate 22, so that the limit column rotates downward, and then the limit column passes through the annular groove 18, thereby realizing the movement of the limit column in 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 to prevent the raw materials from falling into the temporary storage box 2 again, causing the temporary storage box 2 to be full of raw materials, affecting the subsequent negative pressure suction function.

[0042] The limit block 16 can be set as an up and down moving structure as needed. The limit block 16 can move up and down on the connecting rod 1015. A return spring 24 is arranged between the limit block 16 and the connecting rod 1015. The elastic force of the return spring on the limit block is greater than the extrusion 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 is restricted, causing movement interference of the equipment.
