DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] Example 1 See also Figure 1-2A fiber head injection molding feeding device includes a storage tank 1, a distribution device 2 is slidably connected to the inside of the storage tank 1, and the distribution device 2 is used to lay a variety of raw materials inside the storage tank 1. The distribution device 2 includes a piston disk 23 slidably connected to the inside of the storage tank 1, and a threaded rod 30 is installed at one end of the piston disk 23. The outer surface of the threaded rod 30 is connected to a slider 31, and the lower end of the slider 31 is provided with a feed port 32; The dispensing device 2 further includes a first cavity 24 and a second cavity 26 disposed inside the storage tank 1. The first cavity 24 is located on one side of the second cavity 26. A ring 28 is rotatably connected inside the storage tank 1. A first groove 25 and a second groove 27 are also disposed inside the storage tank 1. The first groove 25 is connected to the first cavity 24, and the second groove 27 is connected to the first groove 25. A stirring device 4 is also installed at the lower end of the slider 31, and the stirring device 4 is used to stir the raw materials.
[0026] The optical fiber head is made of a single raw material component by injection molding, and does not have good wear resistance and fire resistance. Wear resistance and fire resistance can be achieved by combining multiple raw materials for injection molding. However, the existing multiple raw material combination feeding equipment will pour all the raw materials into the feeding device together, and mix the multiple raw materials through long-term stirring. Therefore, the mixing efficiency is low, and the raw materials cannot be dried, resulting in bubbles in the injection molded optical fiber head; according to Figure 1 As shown, two kinds of raw materials are placed in the first cavity 24 and the second cavity 26 respectively, and then the piston disc 23 is rotated to drive the slider 31 and the discharge port 32 to rotate. When the slider 31 rotates, it pulls the first hose 29 and the ring 28 to rotate. The ring 28 is rotatably connected to the lower end of the first cavity 24 and the second groove 27. When the upper end of the first hose 29 is connected to the lower end of the first groove 25, the raw material A in the first cavity 24 flows through the first groove 25 to the first hose 29, and the raw material A is transmitted to the lower end of the discharge port 32 through the first hose 29. As the piston disc 23 rotates, the piston disc 2 3 will drive the first hose 29 and the ring 28 to rotate, so that the upper end of the first hose 29 will rotate to the lower end of the second groove 27, so that the second groove 27 is connected with the first hose 29, so that the raw material B at the second cavity 26 flows to the lower end of the discharge port 32 through the first hose 29, so that the discharge port 32 first sprays the raw material A, and then sprays the raw material B, so that the raw materials A and B are distributed in equal amounts at the bottom of the storage tank 1, and the mass is small, and then the piston disc 23 rotates and drives the stirring device 4 to rotate, and the stirring device 4 rotates to stir the small amount of raw materials A and raw materials B to blend with each other, so as to quickly mix; Furthermore, a servo motor is installed inside the piston disc 23, and the servo motor is connected to one end of the threaded rod 30. The threaded rod 30 is driven to rotate by the servo motor. Since the slider 31 is limited at one end of the piston disc 23, the threaded rod 30 drives the slider 31 to move, so that the slider 31 drives the feed port 32 to spray in a spiral manner, thereby covering the bottom of the storage tank 1. When the feed port 32 sprays in a spiral manner, the stirring device 4 rotates and stirs the small amount of raw material A and raw material B to blend with each other, so that the bottom of the storage tank 1 is filled; It should be noted that the interior of the storage tank 1 is divided into several layers of raw materials, each layer of raw materials includes A and raw material B. When the bottom layer of raw materials in the storage tank 1 is filled, the piston plate 23 is slid upward, so that the piston plate 23 drives the discharge port 32 to spray another layer of raw materials, and this cycle is repeated to fill the interior of the storage tank 1, and the stirring and fusion efficiency is high; The lower end of the slider 31 is also provided with an air jet 33, and the air jet 33 is used for drying the raw materials.
[0027] according to Figure 2 As shown, an air jet 33 is installed at the lower end of the slider 31, and air is sprayed through the air jet 33, and the air is blown onto the raw material, thereby drying the raw material.
[0028] Example 2 This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-2 The stirring device 4 includes a connecting sleeve 41 installed at the lower end of the slider 31, the lower end of the connecting sleeve 41 is slidably connected to a connecting column 43, both ends of the connecting column 43 are installed with a short shaft 44, one end of the short shaft 44 is rotatably connected to a rotating plate 46, and the rotating plate 46 is connected to the short shaft 44 through a torque spring 45; A stopper 47 is installed at the lower end of the connecting column 43, and the rotating plate 46 is used to abut against the stopper 47; A cone block 48 is mounted on the lower end of the stopper 47 .
[0029] according to Figure 2 As shown, after the lower material port 32 sprays the raw material, the connecting column 43 is slid downward, so that the connecting column 43 drives the rotating plate 46 to insert into the raw material, and the rotating plate 46 is forced upward by the raw material to swing upward, so that the angle between the two rotating plates 46 changes from 180 degrees to 60 degrees, so that part of the raw material will fall into the angle, and then the connecting column 43 slides upward, thereby driving the rotating plate 46 to slide upward by the connecting column 43, and the rotating plate 46 drives part of the raw material to move upward, so that the raw material accumulated inside is swollen to the upper end of the raw material, which can improve the stirring effect. Secondly, because the air sprayed from the air jet 33 is difficult to flow to the raw material accumulated inside, the swollen raw material contacts the air sprayed from the air jet 33, thereby further improving the drying effect. It should be noted that when the 60-degree angle between the two rotating plates 46 changes to 180 degrees, the rotating plates 46 are driven by the torque spring 45 to abut against the stopper 47, so that the two rotating plates 46 are reset; It should be particularly noted that a cone block 48 is installed at the lower end of the stopper 47, and the cone block 48 is a cone surface, so that the cone block 48 is easy to insert into the raw material.
[0030] Example 3 This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-4 , an adjusting device 5 is provided on the piston disc 23, the adjusting device 5 includes a second one-way valve 57 provided on the piston disc 23, a first one-way valve 56 is provided at the lower end of the storage tank 1, and the first one-way valve 56 and the second one-way valve 57 have opposite valve opening directions; The piston disc 23 is used to separate the interior of the storage tank 1 into a fourth chamber 55 and a third chamber 54; The first shaft 10 and the second shaft 12 are installed inside the piston disc 23, and the outer surface of the second shaft 12 is wound with a second sealing roll 13, and one end of the second sealing roll 13 is connected to one end of the slider 31; A first sealing roll 11 is wound around the outer surface of the first shaft 10, and one end of the first sealing roll 11 is connected to the other end of the slider 31; The first sealing roll 11 and the second shaft 12 both include a rubber roll and a steel roll, and the steel roll is mounted on the outer surface of the rubber roll; An extension column 51 is installed on the upper end of the piston disc 23, and the upper end of the extension column 51 is connected to the square column 22, and the upper end of the square column 22 is connected to the square sleeve 21, and the upper end of the square sleeve 21 passes through the upper end of the storage tank 1, and the square sleeve 21 and the storage tank 1 are connected through a bearing; The upper end of the extension column 51 is slidably connected to the inside of the square column 22; The upper end of the square column 22 is slidably connected to the inside of the square sleeve 21; The extension column 51 is connected to the square column 22 via a second spring 52 .
[0031] according to Figure 3 and Figure 4As shown, a second sealing roll 13 and a first sealing roll 11 are installed at both ends of the slider 31, so that when the slider 31 moves left and right, the slider 31 is used to pull the second sealing roll 13 and the first sealing roll 11 to seal the lower end of the piston disc 23, so that the lower end of the piston disc 23 becomes a piston, and then when the square column 22 pulls the extension column 51 and the piston disc 23 to slide upward, the piston disc 23 will resist on the spring plate 53, and then continue to pull the square column 22 upward to move, so that the upper end of the extension column 51 slides out of the lower end of the square column 22, so that the extension column 51 will stretch the second spring 52, and then when the elastic force of the second spring 52 is greater than the elastic force of the spring plate 53, the piston disc 23 will squeeze the spring plate 53 to deform, so that the piston disc 23 passes over the spring plate 53, and the second spring 52 quickly pulls the piston disc 23 upward to slide, so that The negative pressure of the piston disc 23 extracts the air in the third chamber 54, thereby opening the first one-way valve 56, so that the dry air outside the storage tank 1 enters the third chamber 54 through the first one-way valve 56. Since the raw materials are piled up in the third chamber 54, the dry air at the first one-way valve 56 passes through the raw materials in the third chamber 54 and flows to the lower end of the piston disc 23, so as to further dry the raw materials. Since the second spring 52 has elastic potential energy, the second spring 52 will also push the piston disc 23 to slide downward. At this time, the first one-way valve 56 is closed, and the second one-way valve 57 on the piston disc 23 is opened, so that the moisture at the lower end of the piston disc 23 passes through the second one-way valve 57 and enters the fourth chamber 55. This cycle repeats, allowing the dry air to continuously flow from the bottom of the raw materials to the upper end of the raw materials, and the wet air is discharged, so as to improve the drying effect; Furthermore, the piston disc 23 that slides up and down drives the connecting sleeve 41 and the rotating plate 46 to be inserted into the raw material, so that the raw material is swirled, thereby further improving the stirring effect.
[0032] Example 4 This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-5 A driving device 7 is installed at the upper end of the storage tank 1. The driving device 7 is used to drive the piston disc 23 to slide. The driving device 7 includes a first motor 71 and a second motor 74 installed at the upper end of the storage tank 1. The upper end of the first motor 71 is connected to a first gear 72. The upper end of the square sleeve 21 is also installed with a second gear 73. The first gear 72 is meshed with the second gear 73. A capstan 75 is mounted at one end of the second motor 74, a steel cable 76 is wound around the outer surface of the capstan 75, a bearing ring 77 is rotatably connected to the upper end of the piston plate 23, and the lower end of the steel cable 76 is connected to the lower end of the bearing ring 77; The inner wall of the storage tank 1 is provided with a plurality of spring pieces 53; A pneumatic device 6 is also installed inside the piston disc 23, and the pneumatic device 6 is used to fill the interior of the connecting sleeve 41 with liquid; The pneumatic device 6 includes a plurality of air bags 61 installed inside the piston disk 23, a return spring 62 is installed inside the air bag 61, one end of the return spring 62 is connected to the inner wall of the air bag 61, and the other end of the return spring 62 is connected to the inside of the piston disk 23, a connecting pipe 63 is installed inside the air bag 61, and a manifold 65 is also installed inside the piston disk 23, a plurality of connecting pipes 63 are connected to the manifold 65, a second hose 66 is installed on one side of the manifold 65, and one side of the second hose 66 is connected to one side of the connecting sleeve 41.
[0033] according to Figure 5 As shown, when the slider 31 slides to the right, the slider 31 will drive the extrusion plate 64 to squeeze the airbag 61, so that the liquid inside the airbag 61 enters the connecting tube 63, and the liquid is transmitted to the inside of the connecting sleeve 41 through the connecting tube 63, so that the connecting column 43 is squeezed downward by the liquid, so that the cone block 48 is inserted into the raw material. Then, when the extrusion plate 64 no longer conflicts with the airbag 61, the airbag 61 is pushed to reset by the reset spring 62, and the first spring 42 is pulled to reset the connecting column 43, and the liquid inside the connecting sleeve 41 is squeezed back to the airbag 61 through the connecting column 43, so that the rotating plate 46 drives the raw material to surge, so that the connecting column 43 can slide up and down at the first level to swell the raw material, and cooperate with the piston plate 23 to slide up and down to realize the second level of swell of the raw material, thereby further improving the raw material fusion effect and drying effect.
