Description

Technical Field

[0001] This invention relates to the field of ton barrel rack production and conveying technology, specifically a ton barrel rack production line. Background Technology

[0002] A ton container, also known as an IBC (In-Batch Container), is an essential tool for modern warehousing and transportation of liquid products. It consists of an inner container and a metal frame. The inner container is made of high-molecular-weight, high-density polyethylene through blow molding, which is strong, corrosion-resistant, and hygienic. The metal frame on the outside of the inner container makes the ton container safer and more reliable in use. In the prior art, Chinese invention patent CN108705011A discloses an IBC ton container frame forming production line, including: an actuator; a bending mechanism, arranged opposite to the actuator; a locking mechanism, located beside the actuator and the bending mechanism; a punching mechanism, located on one side of the locking mechanism; and a conveying mechanism, passing through the bending mechanism, the locking mechanism, and the punching mechanism. This invention provides an IBC ton container frame forming production line that integrates the actuator, bending mechanism, locking mechanism, and punching mechanism through the conveying mechanism, processing planar mesh into a three-dimensional closed frame structure, realizing the assembly line production of IBC ton container frames, thereby improving the work efficiency of IBC ton container frame production. Furthermore, the dimensions and weight of the manufactured IBC ton container frames are consistent, thus improving the pass rate of IBC ton container frame production. In the above technology, the entire production line only completes the forming process of the ton container frame. When the ton container frame is hoisted to the conveyor line for transfer after the ton container frame is processed, the impact force generated during the hoisting and falling process directly acts on the rollers and frame of the conveyor line. Long-term impact can easily cause the frame connection parts to loosen, which greatly shortens the overall service life of the production line. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention achieves an elastic connection between the second buffer block and the first buffer block through the cooperation of the first buffer spring, and an elastic connection between the first buffer block and the fixed seat through the cooperation of the second buffer spring. When the hoisting device hoists the ton barrel rack to the conveyor line, the transfer roller is impacted by the ton barrel rack. Since the elastic force of the first buffer spring is less than that of the second buffer spring, the second buffer block vibrates relative to the first buffer block first. During vibration, the second buffer block compresses the first buffer spring and drives the first flexible ball to move relative to the second flexible ball through the first guide block. During displacement, the first flexible ball and the second flexible ball continuously rub against each other. Friction can consume a certain amount of energy, thereby reducing the vibration amplitude. 2. When the impact force is large, the first buffer block vibrates relative to the fixed seat. During the vibration, the first air storage bladder is compressed. The gas inside the first air storage bladder is discharged into the third air storage bladder through the second exhaust pipe. The third air storage bladder expands and pushes the push block to move. When the push block moves, it pushes out the damping rod through the guide of the oblique groove, so that the end of the damping rod contacts the side wall of the second guide groove. When the first buffer block vibrates, it causes the damping rod to rub against the side wall of the second guide groove, further consuming a certain amount of energy and reducing the vibration amplitude. The greater the impact force, the greater the compression amplitude, the greater the force pushing the damping rod, the greater the friction, and the greater the energy consumed. 3. The connection between the fixed seat and the second buffer block is achieved by the cooperation of the fixing bolt and the fixing block. After the fixing block is tightened, the second oblique block is locked with the first oblique block under the cooperation of the collar and the third return spring. When the transfer roller is subjected to impact force, the vibration generated will not cause the fixing bolt to loosen, thus ensuring the stability of the connection between the fixed seat and the second buffer block and the fixed frame and support leg.

Detailed Implementation

[0018] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0019] Example 1: Please refer to Figures 1 to 10 This invention provides a technical solution: a ton-bucket rack production line, comprising: A fixed frame 1 is provided with multiple sets of spaced-apart transfer rollers 2 rotatably mounted on the fixed frame 1, and multiple sets of spaced-apart support legs 3 are provided at the lower end of the fixed frame 1, with a crossbeam 4 provided between two adjacent sets of support legs 3. A buffer assembly is disposed between the fixed frame 1 and the end of the support leg 3 to buffer the impact on the transfer roller 2. The buffer assembly includes a fixed seat 5 connected to the upper end of the support leg 3. A fixing component is used to connect the buffer component to the fixing frame 1 and the support leg 3; By cooperating with the fixing components and the buffer components, the transfer roller 2 on the fixing frame 1 is fixed above the multiple sets of support legs 3, so as to achieve the fixed installation of the transfer roller 2. When the transfer roller 2 is subjected to the impact force of the ton barrel frame, the buffer components effectively buffer the impact.

[0020] Example 2: Figure 3 as well as Figures 5-8 As shown, the ton barrel rack production line disclosed in Embodiment 2 of the present invention has a structure that is basically the same as that in Embodiment 1, except that: The upper end center of the fixed base 5 is provided with a second storage groove 16, and a first buffer block 6 is slidably disposed inside the second storage groove 16. A second buffer spring 18 is provided between the lower end of the first buffer block 6 and the bottom end of the second storage groove 16. The first buffer block 6 is elastically connected to the fixed base 5 through the second buffer spring 18. The outer surface of the first buffer block 6 is provided with a second guide block 20, and the inner sidewall of the second receiving groove 16 is provided with a second guide groove 19 corresponding to the position of the second guide block 20. The second guide block 20 is slidably disposed inside the second guide groove 19. The second guide block 20 has a first clearance groove 28 inside, and a push block 27 is slidably disposed inside the first clearance groove 28. A beveled groove 31 is provided between one end of the push block 27 and the inner wall of the first clearance groove 28. The push block 27 is elastically disposed inside the first clearance groove 28 through the beveled groove 31. The two side walls of the fixed base 5 are provided with a second relief groove 32 at the position corresponding to the first relief groove 28. The second relief groove 32 passes through the side wall of the fixed base 5 and communicates with the first relief groove 28. Each of the second clearance grooves 32 is fitted with a damping rod 30, and the side wall of the push block 27 is provided with a beveled groove 31 at the end position of the damping rod 30. One end of the damping rod 30 is inserted into the inside of the oblique groove 31 through the second relief groove 32; The damping rod 30 has a first limiting block 35 on its side wall, and the inner side wall of the second clearance groove 32 has a first limiting groove 33 at the position of the first limiting block 35. The first limiting block 35 is slidably disposed inside the first limiting groove 33, and a second return spring 34 is provided between the side wall of the first limiting block 35 and the inner wall of the first limiting groove 33. A first air-storing bladder 17 is provided between the lower end of the first buffer block 6 and the inner bottom of the second storage groove 16; A third air-storing airbag 29 is provided between the other end of the push block 27 and the inner sidewall of the first clearance groove 28. A second exhaust pipe 26 is provided between the third air-storing airbag 29 and the first air-storing airbag 17. The first air-storing airbag 17 is connected to the third air-storing airbag 29 through the second exhaust pipe 26. When the impact force is large, the first buffer block 6 vibrates relative to the fixed seat 5. During the vibration, the first air storage bladder 17 is compressed. The gas inside the first air storage bladder 17 is discharged into the third air storage bladder 29 through the second exhaust pipe 26. The third air storage bladder 29 expands and pushes the push block 27 to move. When the push block 27 moves, it pushes out the damping rod 30 through the guide engagement of the oblique groove 31, so that the end of the damping rod 30 contacts the side wall of the second guide groove 19. When the first buffer block 6 vibrates, it causes the damping rod 30 to rub against the side wall of the second guide groove 19, further consuming a certain amount of energy and reducing the vibration amplitude. Moreover, the greater the impact force, the greater the compression amplitude, the greater the force pushing the damping rod 30, the greater the friction, and the greater the energy consumed.

[0021] Example 3: Figure 5 As shown, the ton barrel rack production line disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2, except that: An air storage chamber 21 is provided inside the first buffer block 6 at a position corresponding to the second exhaust pipe 26. A sealing plate 23 is slidably disposed inside the air storage chamber 21, and a first return spring 22 is provided between one end of the sealing plate 23 and the top end of the air storage chamber 21. The sealing plate 23 is elastically disposed inside the air storage chamber 21 by the first return spring 22. A second air-storing airbag 25 is provided between the other end of the sealing plate 23 and the bottom of the inner end of the air-storing cavity 21. A first exhaust pipe 24 is provided between the second air-storing airbag 25 and the second exhaust pipe 26. The second air-storing airbag 25 is connected to the first air-storing airbag 17 and the third air-storing airbag 29 through the cooperation of the first exhaust pipe 24 and the second exhaust pipe 26. The elastic force of the first return spring 22 is greater than the elastic force of the oblique groove 31; When the vibration amplitude of the first buffer block 6 is large, the gas inside the first air storage bladder 17 is discharged into the third air storage bladder 29 through the second exhaust pipe 26. The third air storage bladder 29 expands, pushing the push block 27 to move. When the push block 27 moves, it pushes out the damping rod 30 through the guide of the oblique groove 31, so that the end of the damping rod 30 rubs against the side wall of the second guide groove 19, consuming a certain amount of energy and reducing the vibration amplitude. The greater the impact force, the greater the compression amplitude, but the extension length is limited. The excess gas is discharged into the second air storage bladder 25 for storage through the cooperation of the second exhaust pipe 26 and the first exhaust pipe 24. The setting of the first return spring 22 can, to a certain extent, ensure that the end of the damping rod 30 generates the maximum friction with the side wall of the second guide groove 19.

[0022] Example 4: Figures 3-4 As shown, the ton barrel rack production line disclosed in Embodiment 4 of the present invention has a structure that is basically the same as that in Embodiment 3, except that: A first storage groove 9 is provided at the center of the upper end of the first buffer block 6, and a second buffer block 7 is slidably disposed inside the first storage groove 9. The upper part of the second buffer block 7 is connected to the lower end face of the fixing frame 1. At least one set of spring holes 10 are provided at the bottom of the first storage slot 9. A first buffer spring 11 is provided between the bottom of the spring hole 10 and the lower end face of the second buffer block 7, and the cross-section of the first buffer spring 11 is tapered. The second buffer block 7 has a first guide block 13 on each of its two side walls. The first storage groove 9 has a first guide groove 12 at the position of the first guide block 13 on its inner side wall. The first guide block 13 is slidably disposed inside the first guide groove 12. The inner sidewall of the first guide groove 12 is provided with a plurality of sets of spaced second flexible balls 15, and the sidewall of the first guide block 13 is provided with a plurality of sets of spaced first flexible balls 14 at the positions of each of the second flexible balls 15. The first buffer spring 11 provides an elastic connection between the second buffer block 7 and the first buffer block 6. The second buffer spring 18 provides an elastic connection between the first buffer block 6 and the fixed seat 5. When the transfer roller 2 is impacted, the second buffer block 7 vibrates relative to the first buffer block 6 because the elastic force of the first buffer spring 11 is less than that of the second buffer spring 18. During vibration, the second buffer block 7 compresses the first buffer spring 11 and drives the first flexible ball 14 to move relative to the second flexible ball 15 through the first guide block 13. During the movement, the first flexible ball 14 and the second flexible ball 15 continuously rub against each other. Friction can consume a certain amount of energy, thereby reducing the vibration amplitude. In the event of a small impact, the first buffer spring 11 provides gentle cushioning. In the event of a large impact, the first buffer spring 11 works in conjunction with the second buffer spring 18 to prevent excessive displacement. At the same time, the first buffer spring 11 is set in a conical shape to prevent lateral displacement when the first buffer spring 11 is compressed.

[0023] Example 5: Figure 2 as well as Figures 9-10 As shown, the ton drum rack production line disclosed in Embodiment 5 of the present invention has a structure that is basically the same as that in Embodiment 4, except that: The lower end of the fixed base 5 is provided with a fixed block 8 at the position corresponding to the upper end of the supporting leg 3, and the upper end of the second buffer block 7 is provided with a fixed block 8 at the position corresponding to the lower end of the fixed frame 1. The fixing assembly includes fixing bolts 36 screwed into the interior of each of the fixing blocks 8; The fixing bolt 36 has a first annular groove 41 at the nut position. A collar 43 is slidably disposed inside the first annular groove 41. A third return spring 42 is disposed between the upper end of the collar 43 and the inner top end of the first annular groove 41. The collar 43 is elastically connected to the fixing bolt 36 through the third return spring 42. The upper end of the fixing block 8 is provided with a second annular groove 44 corresponding to the position of the collar 43. The collar 43 is elastically inserted into the interior of the second annular groove 44, and the interior of the second annular groove 44 is provided with first oblique blocks 45 distributed in a circular pattern. The lower end of the collar 43 is provided with a matching second oblique block 46 corresponding to the position of each of the first oblique blocks 45. The sidewall of the first annular groove 41 is provided with a second limiting groove 47 at a position corresponding to the sidewall of the collar 43. A second limiting block 48 is slidably disposed inside the second limiting groove 47, and the second limiting block 48 is connected to the sidewall of the collar 43. A fifth air-storing bladder 49 is provided between the lower end of the second limiting block 48 and the inner bottom end of the second limiting groove 47; A countersunk hole 37 is provided at the upper end of the fixing bolt 36. A pressing block 38 is slidably disposed inside the countersunk hole 37. A fourth air storage bladder 39 is provided between the lower end of the pressing block 38 and the bottom end of the countersunk hole 37. A third exhaust pipe 40 is provided between the fourth air storage bladder 39 and the fifth air storage bladder 49. The connection between the fixed seat 5 and the second buffer block 7 is achieved through the cooperation of the fixing bolt 36 and the fixing block 8. After the fixing block 8 is tightened, the second oblique block 46 is locked and engaged with the first oblique block 45 under the cooperation of the collar 43 and the third return spring 42. When the transfer roller 2 is subjected to impact force, the vibration generated will not cause the fixing bolt 36 to loosen, thus ensuring the stability of the connection between the fixed seat 5 and the second buffer block 7 and the fixed frame 1 and the support leg 3.

[0024] Specifically, the solution is as follows: by cooperating with the fixing block 8 and the fixing bolt 36, the fixing seat 5 is installed to the upper end of the support leg 3, and the second buffer block 7 is installed to the lower end of the fixing frame 1. When the transfer roller 2 is subjected to a small impact, since the elastic force of the first buffer spring 11 is less than the elastic force of the second buffer spring 18, the second buffer block 7 will vibrate relative to the first buffer block 6 first. When vibrating, the second buffer block 7 compresses the first buffer spring 11 and drives the first flexible ball 14 to move relative to the second flexible ball 15 through the first guide block 13. When moving, the first flexible ball 14 and the second flexible ball 15 will continuously rub against each other. Friction can consume a certain amount of energy, thereby reducing the vibration amplitude. When the impact force is large, the first buffer block 6 vibrates relative to the fixed seat 5. During the vibration, the first air storage bladder 17 is compressed. The gas inside the first air storage bladder 17 is discharged into the third air storage bladder 29 through the second exhaust pipe 26. The third air storage bladder 29 expands and pushes the push block 27 to move. When the push block 27 moves, it pushes out the damping rod 30 through the guide engagement of the oblique groove 31, so that the end of the damping rod 30 contacts the side wall of the second guide groove 19. When the first buffer block 6 vibrates, it causes the damping rod 30 to rub against the side wall of the second guide groove 19, further consuming a certain amount of energy and reducing the vibration amplitude. The greater the impact force, the greater the compression amplitude, the greater the force pushing the damping rod 30, the greater the friction, the greater the energy consumed, and the faster the vibration amplitude can be reduced.
