Description

Technical Field

[0001] This utility model relates to a gas damping paddle structure. Background Technology

[0002] In the existing vial capping and feeding process, a large turntable is usually set up, whose main function is to buffer the large batch of material output after the freeze-drying process.

[0003] When a large number of bottles accumulate on the turntable, centrifugal force causes the bottles to tend to align along the center of the turntable and concentrate in the inner ring. To ensure that the feeding demand can be met, a deflector assembly is often provided on the turntable to deflect the bottles gathered in the inner ring to the outer ring, thus allowing them to smoothly enter the feeding track located on the outer ring of the turntable.

[0004] However, most conventional paddle assemblies are controlled by spring devices, which means that the paddle lacks a buffer mechanism when it bounces back after the bottle is pushed out. The rebound force is large, which makes it easy to knock over the bottle located behind the paddle, thus causing risks such as bottle tipping, bottle breakage, and track blockage.

[0005] Therefore, a gas-type damping paddle structure is proposed to address the above problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the existing defects and provide a gas damping paddle structure that effectively reduces shock and buffers, and solves the problems of bottle tipping, bottle breakage, and track blockage caused by excessive paddle rebound force.

[0007] The technical solution to achieve the above objective is: a pneumatic damping paddle structure, including a pneumatic damping box assembly, a central base plate of a pneumatic damping turntable, a turntable paddle shaft cylinder, a paddle mounting block, and a paddle;

[0008] The upper end face of the air damping box assembly is fixedly connected to the center base plate of the air damping turntable. The lower end of the turntable paddle shaft cylinder passes through the center base plate of the air damping turntable and connects to the inside of the air damping box assembly. The upper end of the turntable paddle shaft cylinder is connected to the paddle mounting block, and the paddle is connected to the paddle mounting block.

[0009] Preferably, the air damping box assembly includes a winding reel, a limiting block, a miniature bearing with a screw, a stainless steel wire rope, a compression spring, a spring force adjustment block, a spring force adjustment rod, and a bearing support block;

[0010] The drive shaft inside the turntable paddle cylinder is connected to the winding reel, and the limiting block is connected to the winding reel; one end of the stainless steel wire rope is wound and connected to the winding reel, and the other end passes through two miniature screw bearings and is connected to the compression spring; the other end of the compression spring is connected to the spring force adjustment block, the spring force adjustment block is connected to the spring force adjustment rod, and the spring force adjustment rod is connected to the bearing support block.

[0011] Preferably, the air damping box assembly further includes a hinge block, an air damping piston rod, a medium-precision linear bearing, a magnet, an air damping piston tube, a sealing sleeve, and a speed control screw;

[0012] The hinge block is connected to the winding spool. One end of the air damping piston rod is rotatably connected to the hinge block. The other end of the air damping piston rod is connected to the magnet. The medium-precision linear bearing is connected to the outer wall of the air damping piston rod. The air damping piston tube is connected to the outside of the medium-precision linear bearing. The other end of the air damping piston tube is inserted into the sealing sleeve. The top of the sealing sleeve has a through hole and is connected to the speed control screw.

[0013] Preferably, the hinge block is connected to the reel by a hinge pin.

[0014] Preferably, the tail end of the sealing sleeve is connected to the tail column.

[0015] Preferably, the paddle is arc-shaped.

[0016] Preferably, the central base plate of the air damping turntable is fixedly connected to the air damping box body of the air damping box assembly by screwing.

[0017] Preferably, the turntable paddle shaft sleeve passes through the center base plate of the air damping turntable and is fixedly connected to the air damping box body of the air damping box assembly by screwing.

[0018] The beneficial effects of this invention are as follows: This pneumatic damping paddle structure replaces the traditional single-spring controlled paddle structure. During the paddle's rebound phase, the pneumatic damper generates damping force through piston movement. Simultaneously, the magnet inside the pneumatic damping piston tube generates Ampere force based on the principle of electromagnetic induction. The two work together to enhance the overall damping effect. By consuming the vibration energy during the paddle's rebound, the paddle can rebound slowly, effectively playing a role in shock absorption and buffering. This solves the problems of bottle tipping, bottle breakage, and track blockage caused by excessive paddle rebound force. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a pneumatic damping paddle structure includes a pneumatic damping box assembly 1, a central base plate 2 of a pneumatic damping turntable, a paddle shaft cylinder 3, a paddle mounting block 4, and a paddle 5. The upper end of the pneumatic damping box assembly 1 is fixedly connected to the central base plate 2 of the pneumatic damping turntable. The lower end of the paddle shaft cylinder 3 passes through the central base plate 2 of the pneumatic damping turntable and connects to the interior of the pneumatic damping box assembly 1. The upper end of the paddle shaft cylinder 3 is connected to the paddle mounting block 4, and the paddle 5 is connected to the paddle mounting block 4. The paddle 5 is arc-shaped.

[0027] like Figure 3As shown, the air damping box assembly 1 includes a winding reel 101, a limiting block 102, a miniature screw bearing 103, a stainless steel wire rope 104, a compression spring 105, a spring force adjustment block 106, a spring adjustment rod 107, and a bearing support block 108. A drive shaft inside the turntable paddle cylinder 3 is connected to the winding reel 101, and the limiting block 102 is connected to the winding reel 101. One end of the stainless steel wire rope 104 is wound around and connected to the winding reel 101, and the other end passes through two miniature screw bearings 103 and connects to the compression spring 105. The other end of the compression spring 105 is connected to the spring force adjustment block 106, which is connected to the spring adjustment rod 107, which is connected to the bearing support block 108. The air damping turntable center base plate 2 is fixedly connected to the air damping box body of the air damping box assembly 1 by screws. The turntable paddle shaft cylinder 3 passes through the center base plate 2 of the air damping turntable and is fixedly connected to the air damping box body of the air damping box assembly 1 by screwing.

[0028] like Figure 3 As shown, the air damping box assembly 1 also includes a hinge block 109, an air damping piston rod 111, a high-precision linear bearing 112, a magnet 113, an air damping piston tube 114, a sealing sleeve 115, and a speed control screw 116. The hinge block 109 is connected to the winding reel 101 via a hinge pin 110. One end of the air damping piston rod 111 is rotatably connected to the hinge block 109, and the other end of the air damping piston rod 111 is connected to the magnet 113. The high-precision linear bearing 112 is connected to the outer wall of the air damping piston rod 111, and the air damping piston tube 114 is connected to the outside of the high-precision linear bearing 112. The other end of the air damping piston tube 114 is inserted into the sealing sleeve 115. The top of the sealing sleeve 115 has a through hole and is connected to the speed control screw 116. The tail of the sealing sleeve 115 is connected to the tail post 117.

[0029] Specifically, after the paddle is pulled outward, a rebound force is provided to make the paddle spring back. The resistance generated by the air damper consumes vibration energy, playing a role in shock absorption and buffering, causing the paddle to spring back slowly.

[0030] Specifically, the bottom of the transmission shaft inside the turntable paddle cylinder 3 is inserted into the groove of the winding reel 101 and fixedly connected to it. The limiting block 102 is fixed to the winding reel 101 by screws, so that it can only rotate within a certain range. One end of the stainless steel wire rope 104 passes between two miniature screw bearings 103 and is wound around the winding reel 101, while the other end is connected to the compression spring 105. When the spring force adjustment device is in the initial state, the compression spring 105 is in a compressed state. The bearing support block 108 supports and fixes the spring adjustment rod 107, and the spring force adjustment block 106 slides on the spring adjustment rod to adjust the initial preload of the compression spring.

[0031] Specifically, the hinge block 109 is screwed onto the winding reel 101, and the air damping piston rod 111 is fixedly connected to the hinge block 109 via a hinge pin 110. A magnet 113 is connected to the other end of the air damping piston rod, and a medium-precision linear bearing 112 passes through it. An air damping piston tube 114 is fitted over the bearing, and the other end of the piston tube is inserted into a sealing sleeve 115. The other end of the sealing sleeve is connected to the tailstock 117 and secured by a retaining ring. A through hole is opened at the top of the sealing sleeve, and a speed control screw 116 is inserted therein.

[0032] like Figure 4 As shown, this is a schematic diagram of the application to the turntable. When a large number of bottles are piled up on the turntable, the bottles behind the paddle 5 will push the paddle to rotate outward, pushing the bottles in front of the paddle to the outer edge of the turntable and allowing them to enter the turntable feeding track.

[0033] Specifically, when the paddle begins to rebound, the gas damping piston rod 111 moves along with the paddle 5. The gas damping piston rod 111 moves within the gas damping piston tube 114, causing the gas inside the tube to be compressed and expanded. Due to the compressibility of the gas, the movement of the gas damping piston rod is resisted by the gas, thus cushioning the rebounding paddle.

[0034] In this embodiment, a magnet 113 is installed inside the air damping piston tube. When the air damping piston rod 111 moves, it interacts with the magnet to generate a magnetic field. According to Lenz's law, the piston rod moving in the magnetic field will generate an induced current. This induced current generates an Ampere force in the opposite direction to the piston rod's movement, enhancing the damping effect. The Ampere force and the air damping force work together to dissipate the vibration energy when the paddle rebounds, allowing the paddle to rebound slowly, effectively reducing shock and providing cushioning.

[0035] In this embodiment, the speed control screw 116 of the gas damper can adjust the size of the gas inlet and outlet channel of the piston tube. When the gas damping piston rod rebounds rapidly, the gas in the piston tube, after being adjusted by the speed control screw, will significantly slow down its flow rate in or out of the channel. The reduced flow rate will cause the gas to generate greater resistance to the piston rod, limiting the movement speed of the piston rod and further improving the shock absorption and buffering effect.

[0036] In this embodiment, the paddle features a unique arc-shaped structure. Its tail end has a comb-like pattern, which cleverly matches the construction of the turntable assembly, allowing it to rotate flexibly within the slotted area of ​​the turntable cylinder. The comb-like portion at the tail end of the paddle precisely engages with the groove of the mounting block, and a through hole is provided at this location. By inserting a positioning pin, it is fixedly connected to the mounting block.

[0037] This pneumatic damping paddle structure replaces the traditional single-spring controlled paddle structure. During the paddle's rebound phase, the pneumatic damper generates damping force through piston movement. Simultaneously, the magnet inside the pneumatic damping piston tube generates Ampere force based on the principle of electromagnetic induction. The two work together to enhance the overall damping effect. By consuming the vibration energy during the paddle's rebound, the paddle can rebound slowly, effectively reducing shock and buffering the impact. This solves the problems of bottle tipping, bottle breakage, and track blockage caused by excessive paddle rebound force.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
