Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automatic feeding machine technology, specifically relating to an automatic feeding machine for injection molded parts raw materials that improves feeding stability. Background Technology
[0002] Automatic feeding machines are devices that automatically complete material conveying through mechanical structures and control systems. Their core function is to replace manual labor and achieve a continuous process of "automatic feeding-conveying-unloading". Based on the conveying principle, they can be divided into various types, and the composition and applicable scenarios of different types are significantly different.
[0003] In the injection molding process, an automatic feeder is needed to deliver the injection molding material to the processing equipment. However, when using a spiral automatic feeder, the feed hopper lacks a screening mechanism, causing the injection molding material to fall directly into the feed hopper when manually filling. If the injection molding material sticks together, it can easily cause problems such as the spiral shaft getting stuck and the feed pipe getting blocked when it is fed into the conveying pipe, which will reduce the stability of the material supply. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic feeder for injection molded parts that improves the stability of material supply. It aims to solve the problem in existing technologies where, during the injection molding process, an automatic feeder is needed to deliver the injection molded parts raw materials to the processing equipment. However, when using a spiral automatic feeder, the lack of a screening mechanism in the feed hopper causes the injection molded parts raw materials to fall directly into the feed hopper during manual filling. Furthermore, if the injection molded parts raw materials become sticky, it can easily lead to problems such as the spiral shaft jamming and the conveying pipe becoming clogged when fed into the conveying pipe, thus reducing the stability of the material supply.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeder for injection molded parts that improves material feeding stability, comprising a frame, a conveying pipe mounted on the top of the frame, a conveying mechanism installed inside the conveying pipe, a discharge pipe connected to the bottom of the conveying pipe, a feeding hopper connected to the top of the conveying pipe, a frame inserted inside the feeding hopper, a support block installed on the inner wall of the frame, a vibration spring connected to the top of the support block, a screen adapted to the inside of the frame connected to the top of the vibration spring, a vibration motor connected to the bottom of the screen, a limit plate connected to the outer wall of the screen, a fixing block connected to the outer wall of the feeding hopper, a return spring installed inside the fixing block, a limit baffle connected to the top of the return spring, the conveying mechanism comprising an auger and a servo motor, the auger being rotatably connected inside the conveying pipe, the servo motor being installed at one end of the conveying pipe, and the output shaft of the servo motor passing through the conveying pipe and connected to the auger.
[0006] As a preferred embodiment of the present invention, an automatic feeder for injection molded parts that improves the stability of material supply, the screen can be elastically and telescopically connected to the frame via a vibration spring.
[0007] As a preferred embodiment of the present invention, which improves the stability of material feeding for injection molded parts, the limiting baffle can be elastically telescopically connected to the fixed block through a reset spring.
[0008] As a preferred embodiment of the present invention, an automatic feeder for injection molded parts that improves the stability of material supply, the screen can be detachably and fixedly connected to the limiting baffle through the limiting plate.
[0009] As a preferred embodiment of the present invention, an automatic feeder for injection molded parts that improves the stability of material feeding, the top of the frame is connected to a recessed block, the inside of the frame is rotatably connected to a threaded rod via a bearing, the surface of the threaded rod is threadedly connected to a threaded sleeve, the top of the threaded sleeve is connected to a locking block, the top of the frame is provided with a collection box, one side of the collection box is connected to a first insertion block, the other side of the collection box is connected to a second insertion block, and the bottom end of the conveying pipe is detachably connected to a sealing cap.
[0010] As a preferred embodiment of the automatic feeding machine for injection molded parts that improves the stability of material supply according to this utility model, the bottom end of the locking block is in contact with the top end of the frame, and the locking block can form a threaded transmission with the frame through the threaded sleeve and the threaded rod.
[0011] As a preferred embodiment of the present invention, an automatic feeder for injection molded parts that improves the stability of material supply, the collection box can be detachably and fixedly connected to the vehicle frame through a recessed block, a locking block, a first plug-in block, and a second plug-in block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] Through the cooperation of the frame, support block, vibration spring, vibration motor, limit plate, fixing block, return spring, limit baffle, and screen, when the operator connects the power and starts the vibration motor, the vibration motor will drive the screen to vibrate. Subsequently, the vibration of the screen is transmitted to the vibration spring, which further accelerates the vibration of the screen. When the operator feeds the material, the vibration of the screen can screen the injection molded parts raw materials, avoiding adhesion with the injection molded parts raw materials. This can easily lead to problems such as jamming of the conveying mechanism and blockage of the conveying pipe when feeding into the conveying pipe, thus greatly improving the stability of the material supply. At the same time, the operator presses down the limit baffle to squeeze the return spring to retract, allowing the limit baffle to retract into the fixed block. In this way, the operator can use the limit plate to pull the frame out of the inside of the feeding hopper, which facilitates disassembly and replacement when the screen is damaged.
[0014] Through the cooperation of the collection box, recess, first insertion block, second insertion block, threaded rod, threaded sleeve, and locking block, the operator places the collection box on the frame, then rotates the threaded rod to start it turning. The threaded sleeve then moves along the threads on the surface of the threaded rod. The movement of the threaded sleeve then moves the locking block, which then moves closer to the collection box, pushing the collection box onto the frame. The first insertion block on the collection box then inserts into the recess of the recess. The opening of the locking block then connects with the second insertion block, thus securing the collection box. Next, the operator opens the sealing cover to remove any residual injection molding material from inside the delivery pipe, which then falls into the collection box, facilitating the collection of residual injection molding material.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4This utility model provides the following technical solution: an automatic feeder for injection molded parts that improves feeding stability, comprising a frame 1, a conveying pipe 2 mounted on the top of the frame 1, a conveying mechanism 3 installed inside the conveying pipe 2, a discharge pipe 4 connected to the bottom of the conveying pipe 2, a feeding hopper 5 connected to the top of the conveying pipe 2, a frame 6 inserted inside the feeding hopper 5, a support block 7 installed on the inner wall of the frame 6, a vibration spring 8 connected to the top of the support block 7, and a device adapted to the interior of the frame 6 connected to the top of the vibration spring 8. The screen 22 has a vibration motor 9 connected to its bottom end. The outer wall of the screen 22 is connected to a limit plate 10. The outer wall of the feeding hopper 5 is connected to a fixing block 11. A reset spring 13 is installed inside the fixing block 11. A limit baffle 12 is connected to the top of the reset spring 13. The conveying mechanism 3 includes an auger 31 and a servo motor 32. The auger 31 is rotatably connected inside the conveying pipe 2. The servo motor 32 is installed at one end of the conveying pipe 2. The output shaft of the servo motor 32 passes through the conveying pipe 2 and is connected to the auger 31.
[0023] In practical use, the automatic feeding machine consists of a frame 1, a conveying pipe 2, a conveying mechanism 3, an auger 31, a servo motor 32, a discharge pipe 4, and a feeding hopper 5. In actual use, the operator feeds the injection molding material into the feeding hopper 5, then connects the power supply to start the conveying mechanism 3, which means connecting the power supply to start the servo motor 32. The output shaft of the servo motor 32 drives the auger 31 to start rotating. Then, the injection molding material fed from the feeding hopper 5 will fall into the interior of the conveying pipe 2. Then, the auger 31 drives the injection molding material to start conveying, and then the injection molding material will be sent out from the discharge pipe 4. Finally, the injection molding material is sent to the processing equipment for processing.
[0024] Preferably, the screen 22 can be elastically telescopically connected to the frame 6 via the vibration spring 8. The limiting baffle 12 can be elastically telescopically connected to the fixing block 11 via the return spring 13. The screen 22 can be detachably and fixedly connected to the limiting baffle 12 via the limiting plate 10.
[0025] In practical use, when the operator connects the power supply and starts the vibration motor 9, the vibration motor 9 will drive the screen 22 to vibrate, which facilitates the vibration of the screen 22. Subsequently, the vibration of the screen 22 is transmitted to the vibration spring 8, which further accelerates the vibration of the screen 22, thus further improving the vibratory performance of the screen 22. When the operator feeds the material, the vibration of the screen 22 can screen the injection molding material and avoid sticking to the injection molding material. When feeding into the conveying pipe 2, it can avoid problems such as jamming of the conveying mechanism 3 and blockage of the conveying pipe 2, thus greatly improving the stability of the material supply.
[0026] Simultaneously, the operator presses down on the limiting baffle 12 to compress the reset spring 13, causing the limiting baffle 12 to retract into the fixed block 11. This facilitates the movement of the limiting baffle 12, blocking the front end of the limiting baffle 12 and moving it away from the front end. At the same time, the back end of the limiting baffle 12 is in contact with the front end of the limiting plate 10. This allows the operator to use the limiting plate 10 to pull the frame 6 out of the feed hopper 5, making it convenient to disassemble and replace the screen 22 if it is damaged.
[0027] Preferably, the top of the frame 1 is connected to a recess 15, and the interior of the frame 1 is rotatably connected to a threaded rod 18 via a bearing. A threaded sleeve 19 is threadedly connected to the surface of the threaded rod 18, and a locking block 20 is connected to the top of the threaded sleeve 19. A collection box 14 is provided at the top of the frame 1. A first insertion block 16 is connected to one side of the collection box 14, and a second insertion block 17 is connected to the other side of the collection box 14. A sealing cap 21 is detachably connected to the bottom of the conveying pipe 2. The bottom of the locking block 20 fits against the top of the frame 1, and the locking block 20 can form a threaded transmission with the frame 1 through the threaded sleeve 19 and the threaded rod 18. The collection box 14 can be detachably and fixedly connected to the frame 1 through the recess 15, the locking block 20, the first insertion block 16, and the second insertion block 17.
[0028] In actual use, the operator places the collection box 14 on the frame 1, and then rotates the threaded rod 18 to start rotating. Then the threaded sleeve 19 moves along the thread on the surface of the threaded rod 18. Subsequently, the movement of the threaded sleeve 19 drives the locking block 20 to move. In this way, the locking block 20 can easily cooperate with the threaded rod 18 through the threaded sleeve 19. Then, the locking block 20 fits against the top of the frame 1, thus preventing the threaded sleeve 19 and the threaded rod 18 from rotating together.
[0029] Next, the locking block 20 moves closer to the collection box 14, thereby pushing the collection box 14 to move on the frame 1. Then, the first plug-in block 16 on the collection box 14 is inserted into the recess of the recess 15. Subsequently, the opening of the locking block 20 is connected to the second plug-in block 17, thus fixing the collection box 14. The opening of the recess 15 and the opening of the locking block 20 are the same size as the first plug-in block 16 and the second plug-in block 17.
[0030] Next, the operator opens the sealing cover 21, which allows the residual injection molding material inside the delivery pipe 2 to be removed and fall into the collection box 14, making it convenient to collect the residual injection molding material.
[0031] Working principle: The operator first places the collection box 14 on the frame 1, then rotates the threaded rod 18, causing the threaded sleeve 19 to move along the threads on the surface of the threaded rod 18. The movement of the threaded sleeve 19 in turn causes the locking block 20 to move synchronously. As the locking block 20 gradually approaches the collection box 14, it pushes the collection box 14 to move on the frame 1 until the first insertion block 16 on the collection box 14 is inserted into the recess of the recess 15. At the same time, the opening of the locking block 20 connects with the second insertion block 17, thus completing the fixing of the collection box 14.
[0032] Subsequently, the operator turns on the power and starts the vibration motor 9. When the vibration motor 9 is working, it drives the screen 22 to vibrate. This vibration is transmitted to the vibration spring 8, which further enhances the vibration effect of the screen 22. At this time, the operator feeds in the injection molding material. The vibration of the screen 22 can screen the material to prevent the injection molding material from sticking together. This prevents the material from entering the conveying pipe 2 and causing problems such as the conveying mechanism 3 getting stuck or the conveying pipe 2 getting blocked, thus greatly improving the stability of the material supply.
[0033] Next, the operator feeds the injection molding material into the feeding hopper 5 and turns on the power to start the conveying mechanism 3. At this time, the servo motor 32 starts, causing its output shaft to drive the auger 31 to rotate. After the injection molding material in the feeding hopper 5 falls into the conveying pipe 2, it is conveyed under the drive of the auger 31 and finally sent out from the discharge pipe 4 to the processing equipment for processing.
[0034] After the equipment is used up, the operator opens the sealing cover 21, and the residual injection molding material inside the conveying pipe 2 will fall into the collection box 14, which is convenient for collecting the residual material.
[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
