Description

Technical Field

[0001] This application relates to the field of feeding machines, and more particularly to a vacuum feeding machine. Background Technology

[0002] Vacuum feeders are essential equipment in modern chemical, pharmaceutical, food, metallurgical, building materials, and agricultural industries, among others. They offer improved work efficiency, precise transport, reliable quality, and durability. During the feeding process, raw materials remain completely dry, uncontaminated, free of foreign objects, and leak-proof, achieving automated feeding and avoiding the dangers of high-altitude feeding. They also reduce labor intensity and improve production efficiency, making them indispensable for modern civilized production.

[0003] The utility model patent with announcement number CN216889048U proposes a vacuum feeder to prevent dust from flying, including a vacuum feeder body and a quantitative conveyor. The vacuum feeder body and the quantitative conveyor are connected by a conveying pipe body. The conveying pipe body includes a first conveying pipe and a second conveying pipe. The first conveying pipe has a thread, and the second conveying pipe has a nut. The thread and the nut cooperate. A fixing sleeve is installed on the first conveying pipe, and a locking strip is rotatably provided on the second conveying pipe to engage with the inner wall of the fixing sleeve.

[0004] One of the aforementioned vacuum feeders for preventing dust from flying involves a drive assembly that rotates the clamping strip and engages it in a slot. When the vacuum feeder body vibrates, causing the thread to rotate in the opposite direction, the clamping strip remains in the slot, ensuring that the thread and nut remain engaged regardless of vibration. This prevents loosening at pipe connections and avoids dust flying. This application provides another solution to this problem. Utility Model Content

[0005] To address the aforementioned problems, this application provides a vacuum feeder.

[0006] The vacuum feeder provided in this application adopts the following technical solution:

[0007] A vacuum feeder includes a body, a material pipe and a conveying pipe mounted on the body, and a connecting assembly provided on the material pipe and the conveying pipe. The connecting assembly includes an annular groove formed on the side wall of the conveying pipe. Two U-shaped frames arranged in an annular array are fixedly connected to the side wall of the material pipe. Push plates are slidably arranged in each U-shaped frame. An insertion rod is fixedly connected to one side wall of the push plate. The end of the insertion rod away from the push plate passes through the material pipe and is located in the annular groove. A push-pull rod is rotatably connected to the side wall of the push plate away from the insertion rod. The end of the push-pull rod away from the push plate passes through the U-shaped frame. An L-shaped baffle is fixedly connected to the side wall of the U-shaped frame away from the push plate. An electromagnet is fixedly connected to the side wall of the push-pull rod away from the push plate and is attracted to the L-shaped baffle.

[0008] By adopting the above technical solution, during use, the conveying pipe is threaded into the material pipe to align the annular groove with the insert rod. Then, the push plate is pushed by the push rod to insert the insert rod into the annular groove. The push rod is then rotated to drive the electromagnet to rotate, so that the electromagnet is attracted and connected to the L-shaped baffle to fix the push rod and prevent the insert rod from falling out of the annular groove. This prevents the conveying pipe from rotating in the material pipe and minimizes the problem of loosening at the pipe connection, which could lead to dust flying.

[0009] Preferably, the U-shaped frame has two guide rods inside, and the two ends of the guide rods are fixedly connected to the U-shaped frame and the material tube, respectively, and the push plates are respectively sleeved on the guide rods.

[0010] By adopting the above technical solution, the stability of the push plate can be improved by using the guide rod, preventing the push plate from shaking when the insert rod is pulled out of the material tube, making it difficult to pass the insert rod through the material tube.

[0011] Preferably, a spring is fitted on the push-pull rod, one end of the spring is fixedly connected to the U-shaped frame, and the other end of the spring is fixedly connected to the push plate.

[0012] By adopting the above technical solution, when the push-pull rod is pulled, the spring can be contracted. After the conveying pipe is screwed into the material pipe, the push-pull rod can be released, and the spring can rebound to directly push the push plate, which makes it easy to insert the insertion rod into the annular groove and improves the connection stability.

[0013] Preferably, a rubber sealing gasket for preventing dust leakage is fixedly connected to the side wall of the push plate near the material tube.

[0014] By adopting the above technical solution, after inserting the insert rod into the annular groove, the rubber sealing gasket is made to fit with the material pipe, which can prevent dust from seeping out through the gap between the insert rod and the material pipe and improve the sealing performance between the material pipe and the conveying pipe.

[0015] Preferably, a positioning ring for limiting the screwing depth of the conveying pipe is fixedly connected inside the material tube.

[0016] By adopting the above technical solution, when the conveying pipe is screwed into the material pipe, the conveying pipe abuts against the positioning ring to limit the position of the conveying pipe, which facilitates the positioning of the annular groove and aligns the annular groove with the insertion rod.

[0017] Preferably, the inner diameter of the positioning ring is the same as the inner diameter of the conveying pipe, and an annular guide plate is fixedly connected to the lower surface of the positioning ring.

[0018] By adopting the above technical solution, dust accumulation at the angle between the positioning ring and the material tube can be prevented, thus avoiding dust residue.

[0019] Preferably, a sealing ring is fitted onto the conveying pipe, the sealing ring is fixedly connected to the conveying pipe, and the sealing ring is in contact with the inner wall of the material pipe.

[0020] By adopting the above technical solution, after the conveying pipe and the material pipe are connected, the sealing ring enters the material pipe and fits against the inner wall of the material pipe, which can improve the sealing between the conveying pipe and the material pipe and prevent dust from seeping out through the gap between the conveying pipe and the material pipe, thus preventing dust from flying.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application utilizes the cooperative arrangement of structures such as the insertion rod, L-shaped baffle, and electromagnet. In use, the conveying pipe is threaded into the material pipe, aligning the annular groove with the insertion rod. Then, the push plate is pushed by the push rod to insert the insertion rod into the annular groove. Rotating the push rod then causes the electromagnet to rotate, attracting and connecting with the L-shaped baffle to fix the push rod in place. This prevents the insertion rod from detaching from the annular groove, thus preventing the conveying pipe from rotating within the material pipe. This minimizes the risk of loosening at pipe connections, which could lead to dust emissions.

[0023] 2. When the push-pull rod is pulled, the spring can be compressed. After the conveying pipe is screwed into the material pipe, the push-pull rod is released, and the spring rebound can directly push the push plate, which makes it easy to insert the insertion rod into the annular groove and improves the connection stability.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses a vacuum feeder.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A vacuum feeder includes a body 1, a material pipe 2 and a conveying pipe 3 installed on the body 1, the conveying pipe 3 being threadedly connected to the material pipe 2, and the material pipe 2 and the conveying pipe 3 being provided with connecting components for preventing thread feeding. The connecting components include an annular groove 4, a U-shaped frame 5, a push plate 6, an insert rod 7, a push-pull rod 8, an L-shaped baffle 9, and an electromagnet 10.

[0032] An annular groove 4 is formed on the side wall of the conveying pipe 3. Two U-shaped frames 5 are provided, both fixedly connected to the side wall of the material pipe 2 and forming an annular array. Two push plates 6 are provided, each slidingly disposed within the U-shaped frame 5. Two insertion rods 7 are provided, each fixedly connected to one side wall of the push plate 6. The end of the insertion rod 7 away from the push plate 6 passes through the material pipe 2 and is located in the annular groove 4. Two push-pull rods 8 are provided, each rotatably connected to the side wall of the push plate 6 away from the insertion rod 7. The end of the push-pull rod 8 away from the push plate 6 passes through the U-shaped frame 5. Two L-shaped baffles 9 are provided, each fixedly connected to the side wall of the U-shaped frame 5 away from the push plate 6 and located on one side of the push-pull rod 8. Two electromagnets 10 are provided, each fixedly connected to the side wall of the push-pull rod 8 away from the push plate 6 and respectively attracted and connected to the L-shaped baffle 9.

[0033] Reference Figure 1 and Figure 3 The U-shaped frame 5 has two guide rods 11 inside. The two ends of the guide rods 11 are fixedly connected to the U-shaped frame 5 and the material tube 2 respectively. The push plate 6 is sleeved on the guide rod 11. The guide rod 11 can improve the stability of the push plate 6 and prevent the push plate 6 from shaking when the insertion rod 7 is pulled out of the material tube 2, making it difficult to pass the insertion rod 7 through the material tube 2.

[0034] Reference Figure 1and Figure 3 A spring 12 is fitted on the push-pull rod 8. One end of the spring 12 is fixedly connected to the U-shaped frame 5, and the other end of the spring 12 is fixedly connected to the push plate 6. When the push-pull rod 8 is pulled, the spring 12 can be contracted. After the conveying pipe 3 is screwed into the material pipe 2, the push-pull rod 8 is released, and the push plate 6 can be directly pushed by the spring 12, which makes it convenient to insert the insertion rod 7 into the annular groove 4, and at the same time improves the connection stability.

[0035] Reference Figure 1 and Figure 3 A rubber sealing gasket 13 for preventing dust leakage is fixedly connected to the side wall of the push plate 6 near the material pipe 2. After the insert rod 7 is inserted into the annular groove 4, the rubber sealing gasket 13 is made to fit with the material pipe 2, which can prevent dust from seeping out through the gap between the insert rod 7 and the material pipe 2 and improve the sealing between the material pipe 2 and the conveying pipe 3.

[0036] Reference Figure 3 The material tube 2 is fixedly connected to a positioning ring 14 for limiting the screwing depth of the conveying tube 3. When the conveying tube 3 is screwed into the material tube 2, the conveying tube 3 abuts against the positioning ring 14 to limit the position of the conveying tube 3, which facilitates the positioning of the annular groove 4 and aligns the annular groove 4 with the insertion rod 7.

[0037] Reference Figure 3 The inner diameter of the positioning ring 14 is the same as the inner diameter of the conveying pipe 3. An annular guide plate 15 is fixedly connected to the lower surface of the positioning ring 14, which can prevent dust from accumulating at the angle between the positioning ring 14 and the material pipe 2, resulting in dust residue.

[0038] Reference Figure 1 and Figure 4 A sealing ring 16 is fitted on the conveying pipe 3. The sealing ring 16 is fixedly connected to the conveying pipe 3 and fits against the inner wall of the material pipe 2. After the conveying pipe 3 is connected to the material pipe 2, the sealing ring 16 enters the material pipe 2 and fits against the inner wall of the material pipe 2. This can improve the sealing between the conveying pipe 3 and the material pipe 2 and prevent dust from seeping out through the gap between the conveying pipe 3 and the material pipe 2, causing dust to fly.

[0039] The implementation principle of a vacuum feeder according to an embodiment of this application is as follows: In use, the conveying pipe 3 is threaded into the material pipe 2, so that the conveying pipe 3 abuts against the positioning ring 14 to limit the conveying pipe 3, so that the annular groove 4 is aligned with the insertion rod 7. Then, the push plate 6 is pushed by the push rod 8 to insert the insertion rod 7 into the annular groove 4. Then, the push rod 8 is rotated to drive the electromagnet 10 to rotate, so that the electromagnet 10 is attracted and connected to the L-shaped baffle 9 to fix the push rod 8, preventing the insertion rod 7 from disengaging from the annular groove 4, so that the conveying pipe 3 cannot rotate in the material pipe 2, thus avoiding the problem of loosening at the pipe connection and causing dust to fly.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
