Description

Technical Field

[0001] The utility model relates to the technical field of conveyor lines, in particular to an active buffer device at the terminal of a double-speed chain conveyor line. Background Art

[0002] The double-speed chain conveyor line is a highly efficient and reliable conveying equipment, widely used in logistics warehousing, industrial production, mining and other fields. Its working principle is based on the transmission of chains and sprockets. Through the movement of the chain, materials can be continuously transported along the conveyor line. Compared with traditional conveyor belts, the double-speed chain conveyor line has higher speed and greater carrying capacity.

[0003] In the existing double-speed chain conveyor line technology, when the pallet arrives at the terminal position, the pallet must stop quickly due to the requirements of the production process and efficiency considerations. However, this rapid deceleration process brings a significant problem: since the pallet decelerates too quickly, the loading platform plate placed on the pallet and the material on it cannot adapt to the sudden change in speed in time. Specifically, when the pallet moves at high speed on the conveyor line, the material remains in a relatively stable state due to the continuous driving force. However, when the pallet is about to reach the terminal position and begins to decelerate sharply, the material cannot immediately follow the pallet to decelerate synchronously due to inertia. This sudden change in speed causes the material to generate a large impact force on the loading platform plate, which makes it possible for the material to fall off or tip over from the pallet. It is necessary to perform active buffering protection on the terminal of the double-speed chain conveyor line. Utility Model Content

[0004] The utility model aims to provide an active buffer device at the terminal of a double-speed chain conveyor line to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] An active buffer device at the terminal of a double-speed chain conveyor line comprises a double-speed chain conveyor line and a transfer terminal, wherein the transfer terminal is arranged at one end of the double-speed chain conveyor line, and a liftable transfer conveyor line is arranged inside the transfer terminal; a loading platform plate is placed on the top of the conveying wheel of the double-speed chain conveyor line, a first slide groove is provided at the bottom of the loading platform plate, a deceleration component is arranged inside the first slide groove, and the deceleration component is used to decelerate the loading platform plate arriving at the terminal; a second slide groove is provided on one side of the loading platform plate, and a buffer component is arranged inside the second slide groove, and the buffer component is used to buffer the loading platform plate that hits the terminal.

[0007] The above technical solution is adopted by setting a deceleration component to slow down the loading platform plate entering the transfer terminal from the double-speed chain conveyor line, so as to avoid the situation where the loading platform plate suddenly drops in speed due to suddenly entering the transfer terminal and causes the material to tip over or fall off. A buffer component is also set to buffer the displacement under the action of residual inertia to reduce the impact caused by collision, thereby greatly protecting the transportation of materials on the double-speed chain conveyor line.

[0008] A further improvement of the technical solution of the utility model is that the deceleration assembly includes a sliding rod, which is slidably connected to one side of the inner wall of the first sliding groove, one end of the sliding rod is fixedly connected to the first sliding block, a slow flow groove is provided at the bottom of the loading platform plate, one end of the sliding rod away from the first sliding block extends to the inside of the slow flow groove, a first spring is sleeved on the outer side of the sliding rod, a follower bar is fixedly connected to the bottom of the first sliding block, and a driving plate is fixedly connected to the bottom of the loading platform plate.

[0009] By adopting the above technical solution, the driving speed below the follower bar is greater, so at this speed the follower bar will drive the first slider to move and squeeze the first spring, so that the first slider will slowly decelerate under the elastic force of the first spring.

[0010] A further improvement of the technical solution of the utility model is that a slow flow tube is fixedly connected to the inside of the slow flow groove, a piston plate is slidably connected between the inner walls of the slow flow tube, a sliding rod is located at one end of the slow flow groove and fixedly connected to the piston plate, and a pressure relief pipe is provided on the slow flow tube.

[0011] By adopting the above technical solution, the piston plate is driven to move in the slow flow cylinder through the movement of the sliding rod. The slow flow cylinder is provided with a pressure relief pipe, and its pressure relief speed is limited, thereby limiting the movement of the piston plate under the action of air pressure, thereby limiting the deceleration amplitude to a certain extent, and avoiding the situation where the deceleration amplitude is too large and causes the material to fall off.

[0012] A further improvement of the technical solution of the utility model is that the buffer assembly includes a stop block slidably connected to one side of the loading platform plate, one side of the stop block extends to the inside of the second slide groove and a second spring is fixedly connected to one side of the inner wall of the second slide groove.

[0013] With the above technical solution, when the loading platform plate still moves a certain distance due to inertia and collides with the terminal, the stop block will first make contact and be buffered by the second spring to avoid direct collision between the loading platform plate and the terminal, thereby protecting the loading platform plate.

[0014] A further improvement of the technical solution of the utility model is that a mounting plate is fixedly connected between the inner sides of the double-speed chain conveyor line, a hydraulic cylinder is fixedly installed on the bottom of the mounting plate, the piston rod of the hydraulic cylinder extends to the top of the mounting plate and is fixedly connected to a support head, and rollers are symmetrically rotatably connected on both sides of the support head.

[0015] By adopting the above technical solution, the hydraulic cylinder is controlled to lift the support head, so that one side of the loading platform plate is slightly lifted up under the action of the roller, so that the loading platform plate is temporarily separated from the contact with the transfer conveyor line. At this time, the loading platform plate continues to move under the action of the double-speed chain conveyor line on the drive plate, so as to avoid two different speeds acting on the drive plate at the same time, causing greater wear.

[0016] A further improvement of the technical solution of the utility model is that a filter screen is arranged inside the pressure relief pipe.

[0017] The above technical solution is adopted to prevent dust and other impurities from entering the slow flow tube.

[0018] A further improvement of the technical solution of the utility model is that a rounded corner is provided on one side of the bottom of the driving plate.

[0019] The adoption of the above technical solution enables the driving plate to enter the transfer conveying line more smoothly.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0021] 1. The utility model provides an active buffer device at the terminal of a double-speed chain conveyor line. A deceleration component is set to decelerate the loading platform plate entering the transfer terminal from the double-speed chain conveyor line, so as to avoid the material dumping or falling due to a sudden drop in speed of the loading platform plate caused by the sudden entry into the transfer terminal. A buffer component is also set to buffer the displacement under the action of residual inertia to reduce the impact caused by collision, thereby greatly protecting the transportation of materials on the double-speed chain conveyor line.

[0022] 2. The utility model provides an active buffer device at the terminal of a double-speed chain conveyor line. By setting a slow-flow cylinder, it can give way to the fast-speed drive and limit the speed difference between the two. When the speed difference occurs between the two, the fast-speed part will drive the piston plate to move in the slow-flow cylinder through the movement of the sliding rod. The slow-flow cylinder is provided with a pressure relief pipe, and its pressure relief speed is limited, thereby limiting the movement of the piston plate under the action of air pressure, thereby limiting the deceleration amplitude to a certain extent, and avoiding the situation where the material falls off due to excessive deceleration.

[0023] 3. The utility model provides an active buffer device at the terminal of a double-speed chain conveyor line. By arranging a follower bar and a driving plate at different positions, the area of ​​the bottom of the driving plate is larger than that of the follower bar. Therefore, the follower bar is more likely to slip under driving at different speeds. However, since the driving speed below the follower bar is higher, the follower bar will drive the first slider to move at this speed, thereby achieving coordinated work under different driving speeds and avoiding excessive wear.

[0024] 4. The utility model provides an active buffer device at the terminal of a double-speed chain conveyor line. By setting a hydraulic cylinder and a roller and controlling the operation of the hydraulic cylinder to lift the support head, one side of the loading platform plate is slightly lifted up under the action of the roller, so that the loading platform plate is temporarily separated from the contact with the transfer conveyor line. At this time, the loading platform plate continues to move under the action of the double-speed chain conveyor line on the drive plate, avoiding the situation where two drives of different speeds act on the drive plate at the same time, causing excessive wear or uncoordinated movements.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1-Figure 6As shown, the utility model provides an active buffer device at the terminal of a double-speed chain conveyor line, comprising a double-speed chain conveyor line 1 and a transfer terminal 2, the transfer terminal 2 is arranged at one end of the double-speed chain conveyor line 1, and a liftable transfer conveyor line 3 is arranged inside the transfer terminal 2; the double-speed chain conveyor line 1 is provided with a loading platform plate 4 placed on the top of the conveying wheel, a first slide groove 5 is provided at the bottom of the loading platform plate 4, a deceleration component is arranged inside the first slide groove 5, and the deceleration component is used to decelerate the loading platform plate 4 arriving at the terminal; a second slide groove 14 is provided on one side of the loading platform plate 4, a buffer component is arranged inside the second slide groove 14, and the buffer component is used to buffer the loading platform plate 4 that hits the terminal.

[0036] In this embodiment, a deceleration component is provided to decelerate the loading platform plate 4 entering the transfer terminal 2 from the double-speed chain conveyor line 1, so as to prevent the loading platform plate 4 from suddenly entering the transfer terminal 2 and causing a sudden drop in speed, thereby preventing the material from tipping over or falling off. A buffer component is provided to buffer the displacement under the action of residual inertia, so as to reduce the impact caused by collision, thereby greatly protecting the transportation of materials on the double-speed chain conveyor line 1.

[0037] like Figure 3 and Figure 4 As shown, preferably, the deceleration assembly includes a slide rod 7, which is slidably connected to one side of the inner wall of the first slide groove 5, one end of the slide rod 7 is fixedly connected to the first slider 8, a slow flow groove 6 is opened at the bottom of the loading platform plate 4, one end of the slide rod 7 away from the first slider 8 extends to the inside of the slow flow groove 6, a first spring 9 is sleeved on the outer side of the slide rod 7, a follower bar 10 is fixedly connected to the bottom of the first slider 8, and a driving plate 17 is fixedly connected to the bottom of the loading platform plate 4.

[0038] In this embodiment, the driving speed at the bottom of the follower bar 10 is greater, so at this speed the follower bar 10 drives the first slider 8 to move and squeeze the first spring 9, so that the first slider 8 slowly decelerates under the elastic force of the first spring 9.

[0039] like Figure 4 and Figure 6 As shown, preferably, a slow flow tube 11 is fixedly connected to the inside of the slow flow groove 6, a piston plate 12 is slidably connected between the inner walls of the slow flow tube 11, a slide rod 7 is located at one end of the slow flow groove 6 and fixedly connected to the piston plate 12, and a pressure relief pipe 13 is provided on the slow flow tube 11.

[0040] In this embodiment, the piston plate 12 is driven to move in the slow flow cylinder 11 by the movement of the slide rod 7. The slow flow cylinder 11 is provided with a pressure relief pipe 13, and its pressure relief speed is limited. Therefore, the movement of the piston plate 12 is restricted under the action of air pressure, thereby limiting the deceleration amplitude to a certain extent, and avoiding the situation where the material falls off due to excessive deceleration amplitude.

[0041] like Figure 3 and Figure 4 As shown, preferably, the buffer assembly includes a stopper 15 slidably connected to one side of the loading platform plate 4 , one side of the stopper 15 extends to the inside of the second slide groove 14 and a second spring 16 is fixedly connected to one side of the inner wall of the second slide groove 14 .

[0042] In this embodiment, when the loading platform plate 4 moves a certain distance due to inertia and collides with the terminal, the stop block 15 will first make contact and be buffered by the second spring 16 to avoid direct collision between the loading platform plate 4 and the terminal, thereby protecting the loading platform plate 4.

[0043] Example 2

[0044] like Figure 2 and Figure 5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a mounting plate 18 is fixedly connected between the inner sides of the double-speed chain conveyor line 1, a hydraulic cylinder 19 is fixedly installed at the bottom of the mounting plate 18, a piston rod of the hydraulic cylinder 19 extends to the top of the mounting plate 18 and is fixedly connected to a support head 20, and rollers 21 are symmetrically rotatably connected on both sides of the support head 20.

[0045] In this embodiment, the hydraulic cylinder 19 is controlled to work to lift the support head 20, so that one side of the loading platform plate 4 is slightly lifted up under the action of the roller 21, so that the loading platform plate 4 is temporarily out of contact with the transfer conveyor line 3. At this time, the loading platform plate 4 continues to move under the action of the double-speed chain conveyor line 1 on the drive plate 17, so as to avoid two different speeds acting on the drive plate 17 at the same time, causing greater wear; in addition, under normal circumstances, the top of the roller 21 is flush with the top of the conveying wheel on the double-speed chain conveyor line 1, so as to provide auxiliary support between the double-speed chain conveyor line 1 and the transfer terminal 2.

[0046] Preferably, a filter screen is provided inside the pressure relief pipe 13 .

[0047] In this embodiment, impurities such as dust are prevented from entering the slow flow tube 11 .

[0048] like Figure 3 As shown, preferably, one side of the bottom of the driving plate 17 is provided with a rounded corner.

[0049] In this embodiment, the driving plate 17 is made to be smoother when entering the transfer conveying line 3.

[0050] The following is a detailed description of the working principle of the active buffer device at the terminal of the double-speed chain conveyor line.

[0051] like Figure 1-Figure 6As shown, the loading platform plate 4 placed on the double-speed chain conveyor line 1 will be fed along with the rotation of the conveying wheel. When the component is delivered to the transfer terminal 2, it will hit the terminal and stop moving, and then be driven by the terminal to descend and be sent back to the double-speed chain conveyor line 1. After entering the transfer terminal 2, the speed of the loading platform plate 4 drops rapidly, which will produce a large inertia for the material placed on the loading platform plate 4, and will directly cause the risk of the material falling off or dumping; in the process of the loading platform plate 4 entering the transfer terminal 2 from the double-speed chain conveyor line 1, the driving plate 17 will first contact the transfer conveyor line 3. The feeding speed of the transfer conveyor line 3 is lower than that of the double-speed chain conveyor line 1, which makes the driving plate 17 have two kinds of The drive at the same speed acts, but at this time the area of ​​the driving plate 17 contacting the transfer conveyor line 3 is small, so it will slip temporarily. During the process, the hydraulic cylinder 19 can be controlled to work to lift the support head 20, so that one side of the loading platform plate 4 is slightly lifted up under the action of the roller 21, so that the loading platform plate 4 is temporarily separated from the contact with the transfer conveyor line 3. At this time, the loading platform plate 4 continues to move under the action of the double-speed chain conveyor line 1 on the driving plate 17, until the loading platform plate 4 is about to completely separate from the double-speed chain conveyor line 1, the hydraulic cylinder 19 is controlled to reset. At this time, part of the driving plate 17 is located on the transfer conveyor line 3, and the other part is suspended, and the follower bar 1 0 is still on the double-speed chain conveyor line 1, and two different speeds of driving begin to appear at the bottom of the loading platform plate 4 of the transfer conveyor line 3, and the driving acts on the driving plate 17 and the follower bar 10 respectively. The area of ​​the bottom of the driving plate 17 is larger than the follower bar 10, so the follower bar 10 is more likely to slip under different speeds of driving, but because the driving speed below the follower bar 10 is greater, the follower bar 10 will drive the first slider 8 to move at this speed, squeeze the first spring 9 to slowly decelerate, and drive the slide bar 7 to move, and the slide bar 7 drives the piston plate 12 to move in the slow flow cylinder 11. The slow flow cylinder 11 is provided with a pressure relief pipe 13, and its pressure relief speed is limited, and then under the action of air pressure The movement of the lower limiting piston plate 12 is thereby limited to a certain extent, thereby limiting the amplitude of deceleration to a certain extent, and preventing the material from falling off due to excessive deceleration; and as the follower bar 10 completely separates from the double-speed chain conveyor line 1, the speed of the loading platform plate 4 is gradually reduced, which is equivalent to the transfer conveyor line 3. When the loading platform plate 4 is completely on the transfer conveyor line 3, it is controlled to stop conveying, thereby stopping the loading platform plate 4 from moving; when the loading platform plate 4 still moves for a certain distance due to inertia and collides with the terminal, the stop block 15 will first make contact, and the second spring 16 will buffer it to avoid a direct collision between the loading platform plate 4 and the terminal, thereby protecting the loading platform plate 4.

[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
