Description

Technical Field

[0001] This invention relates to the field of injection molding, and in particular to a multi-channel feeding system based on material forming. Background Technology

[0002] Currently, in injection molding, multiple different raw materials generally need to be blended before molding. Existing technology uses a Roots blower to feed raw materials from different hoppers through a main pipeline. During feeding, the solenoid valve of the hopper is opened, and the material is conveyed to the molding equipment under the action of air force. The materials are pre-mixed before conveying. While this method achieves blending, during the pneumatic conveying process, due to the different densities and masses of the raw materials, the mixed materials are prone to agglomeration in the pipeline, requiring a large air force for conveying; otherwise, the pipeline is easily blocked. Large air forces during feeding can cause pulse pressure fluctuations in the main pipeline or branch pipes. Severe pulse fluctuations can affect the conveying of raw materials, leading to defects such as bubbles or discontinuities during material molding. Furthermore, existing technology conveys different raw materials separately, relying on the same main pipeline. This is not only inefficient but also lacks synchronous control, affecting the accuracy of material distribution and easily leading to uneven distribution and material quality problems.

The other end of each branch pipe is connected to a voltage regulator, and the other end of the voltage regulator is connected to a bypass pipe. The input end of the bypass pipe is detachably connected to each main pipe, and each main pipe is connected to a supply device. Movable arms are symmetrically installed at the rear end of the molding machine body via guide seats. The movable arms are L-shaped, and each movable arm is also connected to a drive mechanism.

[0006] Preferably, each branch pipe is also equipped with a valve body, and the valve body is located in a straight groove. The valve body is equipped with a valve core, which is fixedly connected to the valve stem. A turbine is fixed to the top of the valve stem, and each turbine meshes with a worm gear.

[0008] Preferably, each branch pipe is also equipped with a pressure sensor, and the inside of the pressure regulator is also equipped with a separator and a pressure regulating chamber. The bottom of the separator is connected to the pressure regulating chamber through a material pipe. The separator is also connected to a bypass pipe, and the separator is also equipped with an air outlet pipe, with part of the air outlet pipe extending out of the upper surface of the pressure regulator.

[0009] Preferably, the air outlet pipe is provided with a throat, the throat is located inside the pressure regulator, and the throat is also connected to a connecting pipe, the other end of which is also connected to the pressure regulating chamber.

[0010] Preferably, the connecting pipe is also equipped with a control valve, which is also connected to the air intake pipe. The air intake pipe extends out of the pressure regulator and is connected to an external pressure regulating pump.

[0011] Preferably, two telescopic rods are horizontally symmetrically arranged in the pressure stabilizing chamber. The top of each telescopic rod is fixedly connected to the push plate. The edge of the push plate slides in contact with the inner surface of the pressure stabilizing chamber. A first spring is also fitted on the telescopic rod, and the two ends of the first spring are fixedly connected to the opposite end faces of the push plate and the pressure stabilizing chamber, respectively. The output end of the pressure stabilizing chamber is also connected to the branch pipe.

[0012] Preferably, the driving mechanism includes a mounting plate, a driving electric cylinder, a driving rod, a sliding groove, a positioning rod, a wedge plate, a sleeve arm, a rack, and a roller. The mounting plate is fixed to the molding machine body, and the driving electric cylinder is mounted on the mounting plate.

The bypass pipes enable multi-path transport of different or the same raw materials, reducing pulse fluctuations during transport and preventing unstable material transport pressure caused by fan pulses. Furthermore, the pressure stabilizer not only separates materials but also utilizes the separated airflow to create negative pressure in the pressure stabilizing chamber, facilitating material collection. Finally, the drive mechanism enables simultaneous multi-channel supply of one type of raw material or simultaneous multi-channel supply of different raw materials, ensuring synchronized material supply and more uniform material distribution. This process employs purely mechanical linkage, resulting in a longer equipment lifespan and higher efficiency. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Example 1:

[0029] Please see Figure 1-8A multi-channel feeding system based on material forming includes: a forming machine body 1, wherein a forming chamber 10 is formed inside the forming machine body 1, the forming machine body 1 can be installed on an operating platform and located below a compaction mechanism, or the forming machine body 1 can be used alone, the opening of the forming chamber 10 faces upward, and the forming machine body 1 also has symmetrically formed straight slots 11, wherein a plurality of valve bodies 7 are placed in the straight slots 11, and each valve body 7 is installed on a corresponding branch pipe 3, and each straight slot 11 is movably fitted with a worm gear 12, the end of which is provided with a transmission gear, which can mesh with a rack 167 on a movable arm 14. In this way, the rack 167 will synchronously drive the worm gear 12 to rotate during the movement. During the rotation of the worm gear 12, multiple turbines 13 will be synchronously controlled to rotate. This ensures that the opening and closing time and opening and closing angle of the valve cores 8 in multiple valve bodies 7 are completely synchronized (referring to multiple valve bodies 7 in the same slot 11). Module 2 is located in the molding chamber 10 and includes an upper mold 20 and a lower mold 21. Both the upper mold 20 and the lower mold 21 have several corresponding arc-shaped slots 22 on both sides. The upper mold 20 is fixedly connected to the pressure plate 19. The lower mold 21 is located in the molding chamber 10 and its bottom is in contact with the heating component. The lower mold 21 can be removed through the discharge port 17. The arc-shaped slots 22 are mainly used to clamp the end of the inserted branch pipe 3, so as to prevent the end of the branch pipe 3 from detaching during injection molding. Multiple symmetrically distributed branch pipes 3 mainly feed the raw materials of different main pipes 6 synchronously. The raw materials can also be the same raw materials divided into different branch pipes 3 for transportation. Traditional single-pipe systems are susceptible to pressure fluctuations caused by the pulse fluctuations of the blower. Dividing the system into multiple branch pipes 3 provides multi-channel material supply, reducing pressure fluctuations that occurred when using a single pipe for pneumatic conveying. Each main pipe 6 can supply the same or different materials. One end of each branch pipe 3 extends into the forming chamber 10 and is located in the corresponding arc-shaped groove 22 between the upper mold 20 and the lower mold 21. The other end of each branch pipe 3 is connected to a pressure stabilizer 4, and the other end of the pressure stabilizer 4 is connected to a bypass pipe 5. The input end of the bypass pipe 5 is detachably connected to each main pipe 6, allowing the bypass pipe 5 to be connected to a main pipe at any time. The bypass pipes 6 can be connected to different main pipes 6. When all bypass pipes 5 are connected to one main pipe 6, it is equivalent to dividing the same raw material into different paths for transportation, which can also share pressure fluctuations. Each main pipe 6 is connected to a supply device, which is connected to the fan and the raw material silo. The movable arm 14 is symmetrically installed at the rear end of the molding body 1 through the guide seat 15. The movable arm 14 is L-shaped, and each movable arm 14 is also connected to the drive mechanism 16. The drive mechanism 16 can control the working time and opening and closing angle of each valve body 7 in each straight groove 11. The two movable arms 14 can be used individually or simultaneously.

[0030] When used alone, it is equivalent to the valve body 7 on the same side being able to synchronously control the opening and closing time period and opening and closing angle, in order to provide... Figure 6 For example, there are three valve bodies 7, each of which controls the material conveying rate of a branch pipe 3. Before working independently, simply remove the positioning rod 164 on the wedge plate 165 connected to the other movable arm 14, so that the drive rod 162 is disconnected from the movable arm 14 on one side. At this time, the other end of the drive rod 162 is still fitted on the positioning rod 164 on the wedge plate 165 on this side. Then, insert both ends of the fastening rod into the limiting circular hole 28 of the wedge plate 165 on this side. The fastening rod has a U-shaped structure, which makes the fastening rod horizontally limit the drive rod 162, so that the drive rod 162 will not rotate and prevent the drive rod 162 from rotating during operation. When it is necessary to feed material from both sides at the same time for forming, the drive rod 162 is fixed between the two wedge plates 165 by two detachable positioning rods 164. This process does not require the two ends of the fastening rod to be inserted into the limiting round hole 28 for limiting. The movement of the two wedge plates 165 can be controlled synchronously. While each wedge plate 165 moves up and down, it also pushes the movable arm 14 away from the middle position.

[0031] See Figure 6 Each branch pipe 3 is also equipped with a valve body 7, and the valve body 7 is located in the straight groove 11. The valve body 7 is equipped with a valve core 8, and the valve core 8 is fixedly connected to the valve stem 9. The top of the valve stem 9 is fixed with a turbine 13, and each turbine 13 meshes with a worm gear 12. The worm gear 12 can synchronously control the material on one side to be fed through multiple branch pipes 3, which accelerates the material conveying and makes the material distribution more uniform.

[0032] See Figure 1 and Figure 3 The front end of the molding machine body 1 is also provided with a discharge port 17, which is connected to the molding chamber 10. After the material is formed, the lower mold 21 can be taken out through the discharge port 17, and then the formed material can be taken out from the lower mold 21. Then the lower mold 21 can be put back into the molding chamber 10 through the discharge port 17 for the next forming. The upper part of the molding machine body 1 is also provided with multiple guide rods 18, and pressure plates 19 are movably installed on the multiple guide rods 18. The top of the pressure plate 19 is also fixedly connected to the upper mold 20 through a connecting rod 23. The guide rods 18 are mainly to ensure that the pressure plate 19 can move up and down stably. This ensures that the pressure plate 19 will not tilt during the pressing process of the compaction mechanism, and that the upper mold 20 can be subjected to uniform pressure.

[0033] See Figure 4 and Figure 7Each branch pipe 3 is also equipped with a pressure sensor 24, which mainly detects the material conveying pressure of each branch pipe 3. It can detect in real time, further ensuring that there will be no quality problems of material discontinuity during the molding process. The inside of the pressure stabilizer 4 is also equipped with a separator 40 and a pressure stabilizing chamber 41. The bottom of the separator 40 is connected to the pressure stabilizing chamber 41 through a material pipe 42. The separator 40 is also connected to a bypass pipe 5. The separator 40 is also equipped with an air outlet pipe 43, and part of the air outlet pipe 43 extends out of the upper surface of the pressure stabilizer 4. The mixture coming from the bypass pipe 5 is mainly air and material. First, the bypass pipe 5 tangentially introduces the mixture into the separator 40, so that the material enters the material pipe 42 from the bottom, and the air will swirl and be discharged outward from the top air outlet pipe 43, thus achieving material separation. During the exhaust process of the air outlet pipe 43, a negative pressure is formed at the left end of the pressure stabilizing chamber 41. As a result, the material in the material pipe 42 will enter the right end of the pressure stabilizing chamber 41, i.e. the right end of the push plate 49, due to the pressure difference between the left and right ends. This allows the material to be collected in the pressure stabilizing chamber 41.

[0034] The air outlet pipe 43 is provided with a throat 44, which is located inside the pressure stabilizer 4 and is also connected to a connecting pipe 45. The other end of the connecting pipe 45 is also connected to the pressure stabilizing chamber 41. When the air force is at the throat 44 in the air outlet pipe 43, the pressure on the throat 44 side will decrease due to the Venturi effect. At this time, when the connecting pipe 45 above and below the control valve 46 is opened, the pressure stabilizing chamber 41 at the left end of the push plate 49 will generate negative pressure, and the push plate 49 will move to the left, so that the right end of the push plate 49 will suck in material into the pressure stabilizing chamber 41.

[0035] The connecting pipe 45 is also equipped with a control valve 46, which is also connected to the air intake pipe 47. The air intake pipe 47 extends out of the pressure regulator 4 and is connected to an external pressure regulator pump. Two telescopic rods 48 are also horizontally and symmetrically arranged inside the pressure regulator chamber 41. The top of each telescopic rod 48 is fixedly connected to the push plate 49. The edge of the push plate 49 slides in contact with the inner surface of the pressure regulator chamber 41. A first spring 50 is also fitted on the telescopic rod 48, and the two ends of the first spring 50 are fixedly connected to the opposite end faces of the push plate 49 and the pressure regulator chamber 41, respectively. The output end of the pressure regulator chamber 41 is also connected to the branch pipe 3. This scheme utilizes the Venturi effect generated at the throat 44 to allow material to enter the pressure-stabilizing chamber 41. Then, the control valve 46 controls the upper part of the connecting pipe 45 to close, connecting the air inlet pipe 47 to the connecting pipe 45. In this way, the external pressure-stabilizing pump will deliver a certain pressure of air to the left end of the push plate 49. Under the action of pressure and the first spring 50, the push plate 49 will continuously deliver material to the branch pipe 3. This process can be achieved simply by switching continuously.

[0036] See Figure 2 and Figure 8 The drive mechanism 16 includes a mounting plate 160, a drive cylinder 161, a drive rod 162, a sliding groove 163, a positioning rod 164, a wedge plate 165, a sleeve arm 166, a rack 167, and a roller 168. The mounting plate 160 is fixed to the molding machine body 1, and the drive cylinder 161 is mounted on the mounting plate 160. The telescopic end of the drive cylinder 161 is fixedly connected to the drive rod 162. A sliding groove 163 is formed in the middle of the drive rod 162. Wedge plates 165 are respectively provided on both sides of the moving rod 162, and a positioning rod 164 is detachably installed on each wedge plate 165. The positioning rod 164 is located in the sliding groove 163. A sleeve arm 166 is fixed on one side of each wedge plate 165, and the other end of the sleeve arm 166 is fitted onto the movable arm 14. A rack 167 is also horizontally installed on the movable arm 14. The roller 168 is located between the two wedge plates 165 and is installed on the molding machine body 1 through the connecting shaft 25.

[0037] The movable arm 14 can be used alone or simultaneously. When used alone, only one positioning rod 164 needs to be fixed. First, the drive rod 162 needs to be placed in the designated position. Then, the positioning rod 164 on the corresponding side is first inserted into the sliding groove 163. Then, the two ends of the fastening rod used for limiting are inserted into the limiting round hole 28. This is equivalent to limiting the drive rod 162 in the fastening rod. Under the action of the drive cylinder 161, the drive rod 162 moves downward, causing the positioning rod 164 to drive the wedge plate 165 to move downward. As the wedge plate 165 moves downward, the inclined surface of the wedge plate 165 will contact the roller 168, which will cause the wedge plate 165 to move to the left or right. That is, the wedge plate 165 can move up and down or left and right. When moving left and right, it will drive the movable arm 14 to move along the guide seat 15. During the movement, the rack 167 will mesh with the transmission gear at the end of the worm gear 12, thus realizing synchronous control on the same side.

[0038] When feeding from both sides is required, simply move the drive rod 162 laterally to the designated position, and then install the two positioning rods 164 on the wedge plates 165 respectively. This process does not require fastening rods. As the extension end of the drive cylinder 161 moves downward, it will drive the drive rod 162 to move laterally downward. This will cause the wedge plates 165 on both sides to move downward and left and right synchronously. This will enable the movable arms 14 on both sides to move synchronously. Although the rotation directions of the two worm gears are different, their different directions will not affect the opening and closing angle and opening and closing time of each valve core 8.

[0039] The bottom of the movable arm 14 is also provided with a lug plate 26, which is connected to the connecting shaft 25 by a spring 27. During the downward movement of each wedge plate 165, the movable arm 14 will move to the left or right. In this way, the lug plate 26 will continuously stretch the spring 27 connected to the connecting shaft 25. When it is necessary to reduce or close the valve core 8, simply release the drive cylinder 161. Under the tension of the spring 27, the movable arm 14 will move closer to the roller 168. At this time, the rack 167 will drive the worm gear 12 to rotate in the opposite direction, thereby causing the valve stem 9 to drive the valve core 8 in the valve body 7 to reduce or close.

[0040] Each wedge plate 165 has a limiting hole 28 on its front end face. There are no fewer than two limiting holes 28, which are located on the upper and lower sides of the drive rod 162. The limiting holes 28 are generally used in conjunction with the fastening rod. Their main purpose is to limit the drive rod 162 when it is used on one side, so as to prevent the drive rod 162 from rotating around the positioning rod 164. This ensures that when the extension and retraction end of the drive cylinder 161 extends and retracts, it can drive the wedge plate 165 to move.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
