Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic pipelines, in particular to a logistics braking device for pneumatic pipelines. Background Art

[0002] The pneumatic pipeline logistics system is a combination of modern communication technology and optomechanical integration technology. It connects multiple dedicated pipelines tightly and transmits items in closed pipelines through air pressure, solving the problem of automatic distribution of logistics within buildings. The pneumatic pipeline logistics transmission system is mostly used in smelting, food processing, foundry industry, medical industry and other fields.

[0003] Prior art, such as the patent with publication number CN209988716U, discloses a pneumatic pipeline logistics brake device, including a wall, a fixed sleeve is fixedly installed on the left side of the wall, a material outlet pipe is fixedly installed inside the fixed sleeve and on the top wall of the wall cavity, and a placement table is fixedly installed on the left side of the wall. When the pneumatic pipeline logistics brake device reaches the receiving station of the pneumatic pipeline through the carrier, the pressure of the air compressor on the carrier, its own gravity and the centripetal force when it reaches the slide rail cause it to collide violently with the buffer block. When the carrier reaches the slide rail, the arrival of the carrier is detected by the optical sensor, and then the spray gun starts working through the wire. After the nozzle of the spray gun sprays a fine airflow, it passes through the air outlet and blows onto the carrier that slides into the guide rail, causing a relative force to reduce the impact force of the carrier on the buffer block, thereby achieving the purpose of braking.

[0004] The existing technology still has shortcomings:

[0005] In the above-mentioned prior art, the gas sprayed from the spray gun is used to slow down the carrier containing the items, thereby reducing the impact force of the carrier on the buffer block, thereby achieving the purpose of braking. However, the spray gun is provided as a braking source, the equipment cost is relatively high, and the placement table will also occupy a large space, which is not convenient for use in a small space. Therefore, a pneumatic pipeline logistics braking device is proposed. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a pneumatic pipeline logistics braking device, which can stably brake a carrier, has low manufacturing cost and improves space utilization.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pneumatic pipeline logistics braking device, including a material outlet pipe and a carrier, the outer wall of the material outlet pipe is fixedly connected with an air pipe, the lower end of the material outlet pipe is fixedly connected to a sealing plate, the other end of the air pipe passes through the sealing plate and is connected with the inside of the material outlet pipe, the outer wall of the material outlet pipe is provided with a discharge port for unloading materials, and a sealing door is hinged in the discharge port.

[0008] Preferably, the number of the air pipes is two, and the two air pipes are symmetrically distributed on the outer wall of the material outlet pipe, and the air pipes are symmetrically distributed on the sealing plate.

[0009] Preferably, a mounting groove is provided on the bottom surface of the sealing plate, and a valve is rotatably connected to the inner wall of one end of the air pipe adjacent to the sealing plate, and one end of the valve is inserted into the mounting groove.

[0010] Preferably, two racks are provided on the sealing plate, the racks are slidably connected to the sealing plate, the upper ends of the two racks are fixedly connected to a pressing plate, the lower ends of the racks are located in the mounting groove, one end of the valve located in the mounting groove is fixedly connected to a gear, and the two racks are respectively meshed with the two gears.

[0011] Preferably, the two racks are oppositely distributed, and the two air pipes are fixedly connected with a blocking ring for blocking the valve, and the blocking rings in the two air pipes are oppositely distributed.

[0012] Preferably, the lower ends of the two racks extend out of the mounting groove and are fixedly connected to a push plate.

[0013] Preferably, a clearance groove is provided on the upper surface of the sealing plate, and the pressing plate is movably inserted in the clearance groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model transports the carrier through the material outlet pipe, and the articles are placed in the carrier. When the carrier slides over the fixed connection between the air pipe and the material outlet pipe, part of the gas in the material outlet pipe is transported to the air pipe and blown from the sealing plate to the sliding carrier along the air pipe, which not only reduces the air pressure inside the material outlet pipe pushing the carrier, but also blows air from the bottom of the carrier to reduce its moving speed and reduce the impact of the carrier on the sealing plate, thereby achieving the purpose of braking, with low manufacturing cost, good stability and small space occupation.

[0016] 2. The utility model installs a valve in the air pipe. After the carrier contacts the sealing plate, the valve is driven to rotate by transmission to close the air pipe, and then the blowing to the carrier from below is stopped, thereby avoiding the phenomenon of blowing up the carrier again and improving practicality.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The pneumatic pipeline logistics braking device of this embodiment includes a material outlet pipe 1 and a carrier 2. The outer wall of the material outlet pipe 1 is fixedly connected with an air pipe 5. The lower end of the material outlet pipe 1 is fixedly connected with a sealing plate 6. The other end of the air pipe 5 passes through the sealing plate 6 and is connected with the inside of the material outlet pipe 1. The outer wall of the material outlet pipe 1 is provided with a discharge port 3 for unloading materials, and a sealing door 4 is hinged in the discharge port 3.

[0026] like Figure 1-3As shown, the structure of the pneumatic pipeline logistics brake device in the utility model is similar to the existing pneumatic pipeline logistics brake device structure, such as a pneumatic pipeline logistics brake device disclosed in the patent with publication number CN209988716U. The main improvement of the utility model is to stably brake the carrier 2, with low manufacturing cost and improved space utilization. When the utility model needs to transport the items, the items are placed in the carrier 2, and the carrier 2 is inserted into the material outlet pipe 1. The gas transported in the material outlet pipe 1 drives the carrier 2 to move. When the carrier 2 slides through the connection between the air pipe 5 and the material outlet pipe 1, part of the gas in the material outlet pipe 1 enters the air pipe 5 and moves along the The air pipe 5 transports the material from the sealing plate 6 to the material outlet pipe 1. At this time, the carrier 2 moves toward the sealing plate 6 under the push of the gas in the material outlet pipe 1, and the gas blown out from the air pipe 5 blows the bottom of the carrier 2, thereby achieving deceleration of the carrier 2. At the same time, part of the gas from the material outlet pipe 1 is dispersed into the air pipe 5, thereby reducing the thrust on the carrier 2. The downward thrust of the material outlet pipe 1 on the carrier 2 is greater than the upward thrust of the air pipe 5 on the carrier 2, reducing the impact of the carrier 2 on the sealing plate 6, achieving the purpose of braking. Finally, the carrier 2 falls on the sealing plate 6, the sealing door 4 is opened, and the carrier 2 can be taken out through the discharge port 3. The manufacturing cost is low, the stability is good, and the space occupied is small.

[0027] like Figure 1-4 As shown, there are two air pipes 5, which are symmetrically distributed on the outer wall of the material outlet pipe 1, and symmetrically distributed on the sealing plate 6; the gas in the two material outlet pipes 1 is evenly transported to the two air pipes 5, and the two symmetrical air pipes 5 divert the gas in the material outlet pipe 1 to ensure the stability of the gas in the material outlet pipe 1, thereby ensuring the stable push of the carrier 2.

[0028] like Figure 4 , 5 As shown, a mounting groove 7 is provided on the bottom surface of the sealing plate 6, and a valve 8 is rotatably connected to the inner wall of one end of the air pipe 5 adjacent to the sealing plate 6, and one end of the valve 8 is inserted into the mounting groove 7; after the carrier 2 falls into contact with the sealing plate 6, the valve 8 can be rotated through the mounting groove 7 to make the valve 8 turn horizontal, thereby sealing the air pipe 5, so that the gas in the air pipe 5 will not be blown out, and it is avoided that the gas in the material outlet pipe 1 cannot push the carrier 2, and all moves into the air pipe 5, resulting in the phenomenon that the thrust of the gas blown out of the air pipe 5 increases and pushes the carrier 2 upward.

[0029] like Figure 4As shown, two racks 11 are provided on the sealing plate 6, and the racks 11 are slidably connected to the sealing plate 6, and the upper ends of the two racks 11 are fixedly connected to a pressing plate 10, and the lower end of the racks 11 is located in the mounting groove 7, and one end of the valve 8 located in the mounting groove 7 is fixedly connected to a gear 9, and the two racks 11 are respectively meshed and connected with the two gears 9; because the thrust exerted by the gas in the material outlet pipe 1 on the carrier 2 is greater than the thrust exerted by the air pipe 5 on the carrier 2, the carrier 2 continues to move downward in the material outlet pipe 1 until the carrier 2 contacts the pressing plate 10, thereby driving the pressing plate 10 to move downward, and the pressing plate 10 drives the two racks 11 to move downward, and the racks 11 drives the gear 9 to rotate, so that the valve 8 automatically rotates to block and seal the air outlet end of the air pipe 5, thereby automatically blocking and sealing the air pipe 5, and after the carrier 2 is taken out, the gear 9 is pushed up to drive the valve 8 to turn vertically.

[0030] like Figure 4 , 5 As shown, the two racks 11 are oppositely distributed, and the two air pipes 5 are fixedly connected with a blocking ring 14 for blocking the valve 8, and the blocking rings 14 in the two air pipes 5 are oppositely distributed; the blocking ring 14 can block one direction of rotation of the valve 8, and thus after the valve 8 seals the air pipe 5, the stability of the valve 8 can be maintained.

[0031] like Figure 4 As shown, the lower ends of the two racks 11 extend outside the mounting groove 7 and are fixedly connected with a push plate 12; after the carrier 2 is taken out from the material outlet pipe 1, the push plate 12 located outside the mounting groove 7 is pushed upward, and the push plate 12 drives the two racks 11 to move upward, so as to control the valve 8 to turn vertically and allow the air pipe 5 to discharge air.

[0032] like Figure 4 , 5 As shown, a clearance groove 13 is provided on the upper surface of the sealing plate 6, and the pressing plate 10 is movably inserted in the clearance groove 13; after the pressing plate 10 moves downward, it is inserted into the clearance groove 13, so that the pressing plate 10 and the sealing plate 6 are both in contact with the buffer structure at the end of the carrier 2, thereby increasing the contact surface of the buffer structure of the carrier 2, thereby improving the buffering effect on the items inside the carrier 2 and improving the protection of the items.

[0033] The implementation steps in this embodiment are as follows: when it is necessary to transport the articles, the articles are placed in the carrier 2, and the carrier 2 is inserted into the material outlet pipe 1. The gas transported in the material outlet pipe 1 drives the carrier 2 to move. When the carrier 2 slides through the connection between the air pipe 5 and the material outlet pipe 1, part of the gas in the material outlet pipe 1 enters the air pipe 5 and is transported from the sealing plate 6 to the material outlet pipe 1 along the air pipe 5. At this time, the carrier 2 moves toward the sealing plate 6 under the push of the gas in the material outlet pipe 1, and the gas blown from the air pipe 5 blows the bottom of the carrier 2, thereby achieving the deceleration of the carrier 2. At the same time, part of the gas in the material outlet pipe 1 is separated and discharged. The liquid disperses into the air pipe 5, thereby reducing the thrust on the carrier 2. The downward thrust of the material outlet pipe 1 on the carrier 2 is greater than the upward thrust of the air pipe 5 on the carrier 2, reducing the impact of the carrier 2 on the sealing plate 6, and achieving the purpose of braking. Finally, the carrier 2 falls on the sealing plate 6 and contacts the pressing plate 10, thereby driving the pressing plate 10 to move downward, and the pressing plate 10 drives the two racks 11 to move downward, and the racks 11 drive the gear 9 to rotate, so that the valve 8 automatically rotates to block and seal the air outlet end of the air pipe 5, thereby automatically blocking and sealing the air pipe 5, opening the sealing door 4, and taking out the carrier 2 through the discharge port 3.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
