Description

Technical Field

[0001] The present invention belongs to the technical field of feeding of injection molding machines, and specifically relates to an automatic feeding mechanism for injection molding with precise control. Background Art

[0002] The feeding mechanism of an injection molding machine is responsible for transporting plastic raw materials into the barrel. Commonly, there are two types: screw type and plunger type. The screw type advances the raw materials by rotating the screw and has a pre-compression function; the plunger type relies on the reciprocating movement of the plunger to push. It can accurately control the feeding amount, ensure the stable supply of plastic, which is crucial for the quality consistency of plastic products, such as dimensions, appearance, etc., and needs to cooperate with processes such as plasticization, injection, and pressure holding.

[0003] However, such devices are quite common in the market, but there are certain limitations in their actual use process. They usually simply inject the materials directly into the injection molding machine. However, in actual production scenarios, users often have the need to classify and inject different types of materials. Since the existing devices lack the structure to inject different types of materials according to user needs, this leads to many inconveniences in the operation process. This not only makes it difficult for users to complete the injection and transportation of materials according to the injection requirements of different types of materials, but also reduces the practicality of the device to a certain extent. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides an automatic feeding mechanism for injection molding with precise control, which has the advantage of being able to inject various materials according to requirements.

[0005] To achieve the above object, the present invention provides the following technical solution: An automatic feeding mechanism for injection molding with precise control, including a main body. An adjustment component is installed inside the main body, a locking component is installed directly above the adjustment component on the main body, and a feeding component for feeding materials is arranged at the top of the main body;

[0006] The adjustment component consists of a multi-stage telescopic cylinder, an infrared induction switch, a push seat, a transmission component, a telescopic rod, and an induction plate. During the process of automatically switching the feeding of different types of materials, the multi-stage telescopic cylinder starts to operate, thereby driving the push seat to move from left to right. When the infrared induction switch senses the induction plate, it controls the multi-stage telescopic cylinder to stop moving. Then, the locking component is used to lock the adjustment component and the feeding component, thereby achieving the automatic switching of different types of materials for feeding. At the same time, the transmission component can provide power transmission for the feeding component.

[0007] Preferably, the locking assembly includes a base, an auxiliary seat, a piston ring, a push ring and a telescopic rod. When the telescopic rod operates, it drives the push ring and the piston ring to move downward. The transmission assembly includes a transmission auger. After the piston ring descends, it drives hydraulic oil to be injected into the interior of the transmission assembly. The transmission auger in the transmission assembly, after the hydraulic oil is injected, will be key-connected to the interior of the feeding auger.

A conveying auger that is in transmission connection with the rotating rod is movably installed inside the push seat through a bearing. When the rotating rod rotates, it drives the bevel gear to rotate. The lifting pipe is movably installed on the inner wall of the top of the fixed cylinder through a bearing.

A sealing ring that is movably connected to the meshing wheel is movably installed on the inner wall of the top of the fixed cylinder through a bearing.

[0009] Preferably, the locking assembly further includes a communicating pipe. The communicating pipe is fixed to one side of the outer wall of the top of the push seat. The base is fixed to the outer wall by bolts. A connecting plate is provided on one side outer wall of the base. The sensing plate is fixedly installed on the top outer wall of the connecting plate by bolts.

[0010] Preferably, a lifting groove and a sealing groove are formed on the top outer wall of the base. A lifting ring is slidably connected inside the lifting groove. A connecting groove is formed on the bottom outer wall of the auxiliary seat. A rubber ring is provided on the bottom outer wall of the auxiliary seat. An electric valve is provided inside the auxiliary seat. An auxiliary wheel is movably installed in the inner wall groove on one side of the lifting groove through a bearing. The auxiliary wheel is in mutual contact with the push ring and the lifting ring. When the push ring moves downward, it drives the auxiliary wheel to rotate. When the auxiliary wheel rotates, it drives the lifting ring to be inserted into the connecting groove.

[0011] Preferably, the locking component further includes an installation cylinder, a push rod connected to the push ring is slidably connected inside the installation cylinder, a communication groove communicating with the rubber ring is formed on the top outer wall of the auxiliary seat directly below the installation cylinder, a piston plate fitting with the inner wall of the installation cylinder is installed on the bottom outer wall of the push rod through bolts, and the piston plate can drive air to be injected into the rubber ring through the communication groove during downward movement, the rubber ring bulges due to the injection of air, and the sealing performance when the base and the auxiliary seat are combined is improved through the bulging of the rubber ring.

[0012] Preferably, the feeding component includes a material seat, material grooves are formed inside the material seat and are distributed in an equidistant horizontal structure, a rotating rod is movably installed inside the material grooves through bearings, a feeding auger is arranged at the bottom outer wall of the rotating rod, and the infrared induction switch is fixedly installed on the bottom outer wall of the material seat through bolts.

[0013] Preferably, the feeding component further includes a hydraulic groove, and the piston ring is slidably connected to the inside of the hydraulic groove.

[0014] Preferably, stirring plates are installed on the outer wall of the rotating rod through bolts, and the stirring plates are distributed in an equidistant annular structure.

[0015] Preferably, a pipeline is arranged on one side of the outer wall of the sealing ring, and the other end of the pipeline is fixed on the bottom outer wall of the base and communicates with the hydraulic groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. By setting the adjustment component, when the multi-stage telescopic cylinder inside the adjustment component is operated, the multi-stage telescopic cylinder can effectively drive the movement of the push seat. During the movement of the push seat, the motor and the conveying auger will be further driven to move. Moreover, during the movement of the push seat, the communication pipe and the induction plate can be driven to move synchronously. Based on the corresponding relationship and operating mechanism between the induction plate and the infrared induction switch, the device can classify and feed different categories of materials according to the user's needs, thereby realizing the efficient conveying of materials. This characteristic greatly enhances the practicability of the device. In addition, the device uses the settings of the rotating rod, bevel gear, meshing wheel, lifting pipe and clamping rod to provide power transmission support for the rotating rod inside the feeding component, so as to facilitate the feeding process of the feeding component.

[0018] 2. Through the locking component of the present invention, when the telescopic rod inside the locking component runs, the telescopic rod can drive the push ring to move. During the movement of the push ring, through the coordinated action of the auxiliary wheels, the lifting ring can be accurately inserted into the connecting groove, thereby completing the locking operation of the device. This locking function helps prevent material from falling during the discharging process. Meanwhile, during the movement of the push ring, the piston plate plays its unique role, enabling air to be conveyed into the interior of the rubber ring through the communication groove. Under this effect, the rubber ring will gradually expand and closely adhere to the inner wall of the sealing groove, thus forming a good sealing effect when the device is locked, significantly enhancing the sealing performance and practicality of the device. Additionally, by virtue of the function of the piston ring, the hydraulic oil inside the hydraulic groove can be injected into the sealing ring through a specific pipeline. Subsequently, under the guiding action of the lifting pipe, the hydraulic oil drives the clamping rod to rise, and then the clamping rod accurately engages with the bottom end of the rotating rod. This series of operations provides the necessary power transmission support for the rotation of the rotating rod inside the feeding component, and also enables the device to achieve the operation of the feeding component without the need for many driving devices.

[0019] 3. Through the feeding component of the present invention, when the motor inside the adjustment component starts to run, the power output by the motor can drive the rotating rod to rotate. During the rotation of the rotating rod, through the mutual cooperation of the bevel gear and the meshing wheel, the rotational force of the rotating rod is effectively transmitted, enabling the meshing wheel to drive the lifting rod and the clamping rod to rotate synchronously. Subsequently, the clamping rod drives the transmission auger and the rotating rod to start rotating, and the rotating rod further drives the stirring plate and the feeding auger to rotate together. The feeding auger pushes the material by virtue of its spiral structure, and the stirring plate stirs it to ensure that the material is loose, so that the material can smoothly enter the push seat. This not only completes efficient conveying and processing but also greatly reduces the risk of feeding blockage, improves the operating stability and reliability of the device, and ensures the continuity of the overall production.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 7 shown, the present invention provides a precision-controlled injection molding automatic feeding mechanism, including a main body 1. An adjusting component 2 is installed inside the main body 1, a locking component 3 is installed directly above the adjusting component 2 on the main body 1, and a feeding component 4 for feeding materials is arranged at the top of the main body 1;

[0030] The adjustment component 2 includes a multi-section telescopic cylinder 21, an infrared induction switch 28, a pushing seat 23, a transmission component, a telescopic rod 33, and an induction plate 27. During the process of automatically switching the feeding of different types of materials, the multi-section telescopic cylinder 21 starts to operate, driving the pushing seat 23 to move from left to right. When the infrared induction switch 28 senses the induction plate 27, it controls the multi-section telescopic cylinder 21 to stop moving. Then, the locking component 3 is used to lock the adjustment component 2 and the feeding component 4, thereby achieving the automatic switching of feeding different types of materials. At the same time, the transmission component can provide power transmission for the feeding component 4. When the multi-section telescopic cylinder 21 operates, the multi-section telescopic cylinder 21 can drive the pushing seat 23 to move, and the pushing seat 23 can drive the transmission component to move. When the multi-section telescopic cylinder 21 moves, it can drive the induction plate 27 to move, and through the detection of the infrared induction switch 28, the infrared induction switch 28 can effectively detect the device, and at this time, the multi-section telescopic cylinder 21 will stop working.

[0031] Such as Figure 2 , Figure 4 and Figure 6As shown, preferably, the locking component 3 includes a base 32, an auxiliary base 34, a piston ring 46, a push ring 35 and a telescopic rod 33. When the telescopic rod 33 operates, it drives the push ring 35 and the piston ring 46 to move downward. The transmission component includes a transmission auger 417. After the piston ring 46 moves downward, it drives hydraulic oil to be injected into the interior of the transmission component. The transmission auger 417 in the transmission component, after the hydraulic oil is injected, will be key-connected to the interior of the feeding auger 48. The adjustment component 2 further includes a push groove 22, and a push seat 23 is slidably connected to the interior of the push groove 22. The multi-stage telescopic cylinder 21 is fixed to the outer wall of one side of the main body 1 by bolts. The output end of the multi-stage telescopic cylinder 21 is fixed to the outer wall of one side of the push seat 23 by bolts. A motor 24 is installed on the outer wall of one end of the push seat 23 by bolts. When the multi-stage telescopic cylinder 21 operates, the multi-stage telescopic cylinder 21 drives the push seat 23 to move. When the push seat 23 is operating, the push seat 23 drives the motor 24 to move. When the motor 24 is started, the motor 24 can provide power for the operation of the transmission component. Then, by starting the telescopic rod 33, the multi-stage telescopic rod 33 can drive the push ring 35 to move. The push ring 35 injects hydraulic oil into the interior of the transmission component by the action of the hydraulic oil, thereby promoting the transmission auger 417 to be key-connected to the bottom of the feeding auger 48. The transmission component further includes a fixed cylinder 410 and a lifting pipe 415. A rotating rod 47 is movably installed inside the fixed cylinder 410 through a bearing. A bevel gear 413 is installed on the outer wall of the rotating rod 47 by bolts. A conveying auger 25 that is drivingly connected to the rotating rod 47 is movably installed inside the push seat 23 through a bearing. By the rotation of the rotating rod 47, the bevel gear 413 is driven to rotate. The lifting pipe 415 is movably installed on the inner wall of the top of the fixed cylinder 410 through a bearing. A clamping rod 416 is slidably connected to the interior of the fixed cylinder 410. A meshing wheel 414 that meshes with the bevel gear 413 is installed on the bottom end of the outer wall of the lifting pipe 415 by bolts. A sealing ring 412 that is movably connected to the meshing wheel 414 is movably installed on the inner wall of the top of the fixed cylinder 410 through a bearing. When the motor 24 operates, the motor 24 drives the rotating rod 47 inside the transmission component to rotate. During the rotation of the rotating rod 47, the rotating rod 47 drives the bevel gear 413 on its outer wall to rotate. During the rotation of the bevel gear 413, the bevel gear 413 can drive the lifting pipe 415 to rotate by meshing with the meshing wheel 414. During the rotation of the rotating rod 47, the rotating rod 47 drives the conveying auger 25 to rotate, thereby effectively conveying the material.

[0032] As Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the locking component 3 further includes a connecting pipe 31. The connecting pipe 31 is fixed to one side of the outer wall of the top of the pushing seat 23. The base 32 is fixed to the outer wall of the base 32 by bolts. A connecting plate 26 is provided on one side outer wall of the base 32. The induction plate 27 is fixedly installed on the top outer wall of the connecting plate 26 by bolts. When the pushing seat 23 moves, the pushing seat 23 will drive the connecting pipe 31 to move. The connecting pipe 31 will drive the base 32 and the connecting plate 26 to move. The connecting plate 26 will drive the induction plate 27 to move; a lifting groove 36 and a sealing groove 314 are formed on the top outer wall of the base 32. A lifting ring 37 is slidably connected inside the lifting groove 36. A connecting groove 39 is formed on the bottom outer wall of the auxiliary seat 34. A rubber ring 315 is provided on the bottom outer wall of the auxiliary seat 34. An electric valve 49 is provided inside the auxiliary seat 34. An auxiliary wheel 38 is movably installed in the inner wall groove on one side of the lifting groove 36 through a bearing. The auxiliary wheel 38 is in mutual contact with the pushing ring 35 and the lifting ring 37. By the downward movement of the pushing ring 35, the auxiliary wheel 38 is driven to rotate. By the rotational movement of the auxiliary wheel 38, the lifting ring 37 is driven to be inserted into the inside of the connecting groove 39. When the telescopic rod 33 is started, the telescopic rod 33 will drive the pushing ring 35 to move vertically up and down, thereby providing power for the locking of the locking component 3. When the lifting ring 37 is lifted or lowered, the lifting ring 37 will move up and down inside the connecting groove 39 and the lifting groove 36. And the setting of the rubber ring 315 of this device can help to provide sealing for the locking of the base 32 and the auxiliary seat 34. When the pushing ring 35 moves downward, the pushing ring 35 can drive the auxiliary wheel 38 to rotate. And due to the mutual contact of the auxiliary wheel 38, the pushing ring 35 and the lifting ring 37, the lifting ring 37 can effectively perform up and down lifting treatment; the locking component 3 further includes an installation cylinder 310. A push rod 311 connected to the pushing ring 35 is slidably connected inside the installation cylinder 310. A communication groove 313 communicating with the rubber ring 315 is formed on the top outer wall of the auxiliary seat 34 directly below the installation cylinder 310. A piston plate 312 in contact with the inner wall of the installation cylinder 310 is installed on the bottom outer wall of the push rod 311 by bolts. When the piston plate 312 moves downward, air can be driven to be injected into the rubber ring 315 through the communication groove 313. By the injection of air, the rubber ring 315 generates a swelling action. By the swelling of the rubber ring 315, the sealing performance when the base 32 and the auxiliary seat 34 are combined is improved. When the pushing ring 35 descends, the pushing ring 35 will drive the push rod 311 to move. The push rod 311 will drive the piston plate 312 to move inside the installation cylinder 310. Thus, air will be injected into the inside of the rubber ring 315 through the action of the communication groove 313. And during the continuous injection of air, the rubber ring 315 will be swollen, so that the rubber ring 315 will be swollen and fit inside the sealing groove 314.

[0033] As Figure 1 , Figure 2 and Figure 4As shown, the feeding component 4 includes a seat 41. Inside the seat 41, there are evenly spaced horizontal grooves 42. Inside the grooves 42, a rotating rod 44 is movably installed through bearings. At the bottom end of the outer wall of the rotating rod 44, there is a feeding auger 48. The infrared induction switch 28 is fixed to the bottom outer wall of the seat 41 by bolts. When the rotating rod 44 rotates, it drives the feeding auger 48 on the bottom end of its outer wall to rotate, so that the feeding auger 48 can drive the material for discharging and conveying. And the infrared induction switch 28 integrates a control chip inside. Moreover, such an infrared induction switch 28 is a mature part in the market, so it will not be elaborated here. The feeding component 4 also includes a hydraulic groove 43. A piston ring 46 is slidably connected to the inside of the hydraulic groove 43. The opening of the hydraulic groove 43 can provide an installation position for the piston ring 46. And when the piston ring 46 moves, it can drive the hydraulic oil inside it to move. On the outer wall of the rotating rod 44, there is a stirring plate 45 installed by bolts. The stirring plates 45 are distributed in an evenly spaced annular structure. When the rotating rod 44 rotates, it can drive the stirring plates 45 to rotate. The stirring plates 45 can effectively stir the material to prevent the material from being blocked. On one side of the outer wall of the sealing ring 412, there is a pipe 411. The other end of the pipe 411 is fixed to the bottom outer wall of the base 32 and is connected to the hydraulic groove 43. When the hydraulic oil is injected, the hydraulic oil can be injected into the inside of the sealing ring 412 through the pipe 411. And during the continuous injection process, the hydraulic oil can enter the inside of the lifting pipe 415, so as to provide assistance for the lifting of the clamping rod 416.

[0034] Working principle and usage process of the present invention: First, place the device on the top of the injection molding machine, and connect the discharge port of the main body 1 to the feed port of the injection molding machine. Then, inject the material into the interior of the material tank 42. At this time, start the multi-stage telescopic cylinder 21 according to the injection requirements of the material. The multi-stage telescopic cylinder 21 will drive the push seat 23 to move. The push seat 23 will drive the connecting pipe 31, and the connecting pipe 31 will drive the connecting pipe 31, the base 32 and the connecting plate 26 to move. The connecting plate 26 will drive the induction plate 27 to move. At this time, by operating the infrared induction switch 28, the infrared induction switch 28 will make the base 32 accurately correspond directly below the auxiliary seat 34 by corresponding and matching with the induction plate 27. At this time, start the telescopic rod 33. The telescopic rod 33 will drive the push ring 35 to move. The push ring 35 will slide downward inside the auxiliary seat 34. During the movement of the push ring 35, the push ring 35 will be inserted into the interior of the base 32. And during the movement of the push ring 35, the push ring 35 will fit the auxiliary wheel 38, enabling the auxiliary wheel 38 to rotate. During the rotation of the auxiliary wheel 38, the auxiliary wheel 38 can drive the lifting ring 37 to rise. The lifting ring 37 will be inserted into the interior of the connecting groove 39. And during the downward movement of the push ring 35, the push ring 35 will drive the push rod 311 to move. During the downward movement of the push rod 311, the push rod 311 will drive the piston plate 312 to move. During the movement of the piston plate 312, the piston plate 312 will inject the air inside the installation cylinder 310 into the interior of the communication groove 313. And during the continuous movement of the piston plate 312, the air will be injected into the interior of the rubber ring 315, causing the rubber ring 315 to expand and fit against the inner wall of the sealing groove 314. During the downward movement of the push ring 35, the push ring 35 will drive the piston ring 46 to move. The piston ring 46 can make the hydraulic oil enter the interior of the pipeline 411 by fitting with the hydraulic groove 43. And during the movement of the piston ring 46, the piston ring 46 will squeeze the spring. And during the continuous injection of the hydraulic oil, the hydraulic oil can, by the action of the pipeline 411, make the pipeline 411 inject the hydraulic oil into the interior of the sealing ring 412. During the continuous injection of the hydraulic oil, the hydraulic oil can enter the interior of the lifting pipe 415, causing the clamping rod 416 to rise. Subsequently, start the electric valve 49. When the electric valve 49 is opened and the clamping rod 416 continues to rise, the clamping rod 416 will be key-connected to the outer wall of the bottom end of the rotating rod 44. Finally, start the motor 24. The motor 24 will drive the rotating rod 47 to rotate. During the rotation of the rotating rod 47, the rotating rod 47 will drive the bevel gear 413 to rotate. During the rotation of the bevel gear 413, the bevel gear 413 can drive the meshing gear 414 to rotate by meshing with the meshing gear 414. The meshing gear 414 will drive the sealing ring 412 and the lifting pipe 415 to rotate. During the rotation of the lifting pipe 415, the lifting pipe 415 will drive the clamping rod 416 to rotate. The clamping rod 416 will drive the transmission auger 417 and the rotating rod 44 to rotate.During the rotation of the rotating rod 44, the rotating rod 44 can drive the stirring plate 45 and the feeding auger 48 to rotate, so that the material will enter the inside of the pushing seat 23. During the rotation of the rotating rod 47, the rotating rod 47 will drive the conveying auger 25 to rotate, so that the conveying auger 25 can drive the material to be discharged outside the device.
