A coding machine bracket for seamless gas cylinder production

Abstract

This invention discloses a coding machine bracket for seamless gas cylinder production, relating to the field of gas cylinder coding machine technology. This coding machine bracket for seamless gas cylinder production improves upon the design of a coding machine bracket used on an automated gas cylinder conveyor line. The bracket, equipped with the coding machine, can be moved around for gas cylinder coding. It is particularly suitable for situations where a gas cylinder conveyor line cannot be installed. In such cases, the operator only needs to move the floor frame to the gas cylinder to be coded. Then, four rollers clamp the gas cylinder and automatically rotate around it, allowing the coding machine to perform the coding work. This eliminates the need for manual handling of the gas cylinder, significantly reducing the labor intensity of the coding process.

Description

Technical Field

[0001] This invention relates to the field of gas cylinder coding machine technology, specifically a coding machine bracket for seamless gas cylinder production. Background Technology

[0002] In the final stage of seamless gas cylinder production, it is necessary to mark the outer wall of the gas cylinder with text and slogans related to the applicable scenarios of the gas cylinder, according to the usage requirements of the gas cylinder. Existing technologies use handheld marking machines for marking, while others combine marking with marking brackets in the gas cylinder conveyor line. The latter involves setting up a marking machine bracket on one side of the gas cylinder conveyor line, with the marking machine fixedly installed on the bracket. When the gas cylinder is conveyed to the marking machine bracket and rotates, the marking machine can mark the outer wall of the gas cylinder in a circumferential manner relative to the gas cylinder. For example, Chinese Patent No. CN106553463A discloses a height-adjustable marking machine bracket and its usage method.

[0003] Existing coding machine stands for gas cylinder production have undergone numerous improvements to offer various adjustment options, such as adjusting the height and angle, greatly enhancing adaptability. However, many small gas cylinder manufacturers lack the resources to set up coding conveyor lines for cylinder coding. Many still manually use handheld coding machines to mark cylinders. Traditional coding machines on conveyor lines, where the cylinders rotate automatically, do not require moving the machine stand. However, these stands are unsuitable for scenarios without automated cylinder conveyor lines, exhibiting poor adaptability. Furthermore, there are currently no coding machine stands on the market suitable for marking cylinders without conveyor lines and requiring movement.

[0004] Therefore, it is necessary to provide a coding machine bracket for seamless gas cylinder production to solve the above-mentioned technical problems. Summary of the Invention

[0021] (III) Beneficial Effects

[0022] This invention provides a coding machine bracket for seamless gas cylinder production. Compared with the prior art, it has the following advantages:

[0023] 1. By improving the design of the coding machine bracket used on the automatic gas cylinder conveyor line, the entire coding machine bracket can be moved to perform coding work on gas cylinders after the coding machine is mounted. It is especially suitable for gas cylinder coding work when there is no space to set up a gas cylinder conveyor line. In this case, the operator only needs to move the floor frame to the gas cylinder to be coded. Then the four rollers can clamp the gas cylinder and automatically surround the gas cylinder so that the coding machine can surround the gas cylinder to perform coding work. There is no need for the operator to hold the gas cylinder and rotate it to perform coding work, which greatly reduces the labor intensity of gas cylinder coding work.

[0024] 2. The four rollers can clamp gas cylinders of various diameters. While clamping gas cylinders of different diameters, the coding machine can always maintain a certain distance between the coding side and the outer wall of the gas cylinder. That is, while adjusting the distance between the two clamping plates, the position of the coding machine can be adjusted synchronously. This ensures that when the rollers are clamped on the outer wall of the coding machine, the coding machine is also adjusted to be close to the outer wall of the gas cylinder. There is no need to adjust after clamping. Instead, the position adjustment of the coding machine is completed during the clamping process, saving operation time.

[0025] 3. By sliding two rods onto the adjustment plate on the carrier box, and the angle of the adjustment plate is adjustable, the clamp can be flipped, and the entire bracket can be folded when stored, reducing the storage space occupied, improving accessibility, and facilitating storage.

[0026] 4. By arranging a clamping mechanism, the coding machine can be detachably mounted on the carrier plate. The clamping process is automated, eliminating the need for manual disassembly and assembly between the coding machine and the carrier plate. This further reduces manual operation steps and makes it more convenient to use. Moreover, the clamping power is used to complete the clamping and fixing of the coding machine, reducing the investment in power equipment and reducing equipment manufacturing and operation and maintenance costs.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1, please refer to Figures 1 to 10 This embodiment provides a technical solution: a coding machine bracket for seamless gas cylinder production, including a floor frame 1, rollers 101 fixed at the bottom of the floor frame 1, a vertical frame 2 fixed at the top of the floor frame 1, a first screw 3 rotatably connected to the inner wall of the vertical frame 2 through a bearing, a first motor 4 fixed on the floor frame 1 directly below the first screw 3, the bottom of the first screw 3 being fixed to the output end of the first motor 4, a lifting block 5 slidably connected to the inner wall of the vertical frame 2, the lifting block 5 being threadedly connected to the first screw 3 through a threaded hole, and a carrier box 51 fixed on the lifting block 5;

[0045] When it is necessary to drive the carrier box 51 to rise or fall, the first motor 4 is driven to work, which drives the first screw 3 to rotate. The first screw 3 drives the lifting block 5 to rise or fall inside the vertical frame 2, thereby achieving the effect of driving the carrier box 51 up and down.

[0046] Slide rods 6 are symmetrically slidably installed on the carrier box 51 through sliding holes. Clamping plates 7 are fixed to the opposite ends of the two slide rods 6. Rotating rods 8 are symmetrically rotatably connected to the sides of the two clamping plates 7 that are close to each other through bearings. Rollers 9 are symmetrically fixed to the outer walls of the rotating rods 8. Rubber sleeves 10 are fixed to the outer walls of the rollers 9. The rollers 9 need to clamp the gas cylinder in the end. The rubber sleeves 10 increase the friction between the outer walls of the rollers 9 and the outer walls of the gas cylinder. Rotating components 11 for driving the rotating rods 8 to rotate are fixed to the sides of the two clamping plates 7 that are close to each other.

[0047] The rotating assembly 11 includes a worm gear 111 fixed in the middle of the rotating rod 8. Two worms 112 fixed to each other are rotatably connected to the side of the clamping plate 7 near the worm gear 111 via bearings. The two worm gears 111 are respectively meshed with the two worms 112. A second motor 113 is fixed to the side of the clamping plate 7 near the worms 112. One end of one worm 112 near the second motor 113 is fixed to the output end of the second motor 113. When the rotating rod 8 needs to be driven to rotate, the second motor 113 is driven to rotate, which drives the worm 112 to rotate, which in turn drives the worm gear 111 to rotate, thereby driving the rotating rod 8 to rotate, causing the drum 9 to rotate.

[0048] The inner wall of the carrier box 51 is rotatably connected to a bidirectional screw 12 via a bearing. Two slide rods 6 are respectively threaded to the two ends of the bidirectional screw 12 via threaded holes. A drive assembly 13 for driving the bidirectional screw 12 to rotate is fixed on the inner wall of the carrier box 51. The coding machine 18 is mounted on the drive assembly 13. The drive assembly 13 is also used to drive the coding machine 18 to move closer to or away from the gas cylinder.

[0049] After the height of the carrier box 51 is adjusted to a suitable height, specifically the height at which the coding machine 18 reaches the position where the gas cylinder needs to be coded, the floor frame 1 is pushed close to the gas cylinder, so that the four rollers 9 are positioned in pairs on both sides of the gas cylinder. Through the operation of the drive component 13, the bidirectional screw 12 is driven to rotate, which in turn allows the two slide bars 6 to move closer to each other and the two clamping plates 7 to move closer to each other. Finally, the four rollers 9 are pressed against the outside of the gas cylinder to clamp the gas cylinder. While the drive component 13 is working, the coding machine 18 can be brought close to the gas cylinder.

[0050] After clamping the gas cylinder, the first motor 4 works again, causing the lifting block 5 and the vertical frame 2 to move relative to each other. Since the carrier box 51 is clamped and fixed on the gas cylinder, the vertical frame 2 and the floor frame 1 are raised a certain distance relative to the gas cylinder, causing the roller 101 to separate from the ground. The floor frame 1 only needs to be raised when the ground is uneven. However, most existing factory floors use self-leveling flooring, which is flat. Therefore, after clamping the gas cylinder, the floor frame 1 does not need to be raised when marking the gas cylinder. The floor frame 1 is driven to roll on the ground. Finally, the rotating component 11 works, driving the rotating rod 8 to rotate, which allows the roller 9 to roll. The roller 9 rolls on the outer wall of the gas cylinder while being clamped to it. At the same time, the marking machine 18 works to mark the gas cylinder. After marking is finished, the first motor 4 works again, the roller 101 contacts the ground again, and the drive component 13 works to release the clamping work, completing the marking work on the gas cylinder.

[0051] The drive assembly 13 includes a third motor 131 fixed to the outer wall of the support box 51 near the lifting block 5. A third screw 132 is rotatably connected to the inner wall of the support box 51 via bearings. The third screw 132 is perpendicular to the bidirectional screw 12. One end of the third screw 132 is fixed to the output end of the third motor 131. A driving bevel gear 133 is fixed to the end of the third screw 132 near the bidirectional screw 12. A driven bevel gear 134 is fixed to the middle of the bidirectional screw 12. The driving bevel gear 133 and the driven bevel gear 134 are connected. The meshing connection is as follows: the driving bevel gear 133 and the driven bevel gear 134 have the same specifications, and the third screw 132 and the double screw 12 also have the same specifications. The top of the carrier box 51 is slidably connected to the carrier plate 135 via a linear slide rail. The linear slide rail is a prior art technology and consists of a slide rail and a slider. In this application, the slide rail is fixed on the top surface of the carrier box 51, the slider is fixed on the bottom surface of the carrier plate 135, and the slider is slidably connected to the outer wall of the slide rail, thereby completing the sliding connection between the carrier plate 135 and the carrier box 51.

[0052] A connecting strip 136 is fixed to the bottom of the support plate 135. The connecting strip 136 extends through the support box 51 to the inside of the support box 51. The lower end of the connecting strip 136 is threaded to the third screw 132 through a threaded hole. A stop block 137 is fixed to one side of the top surface of the support plate 135. A clamping mechanism 138 is fixed on the support plate 135. One side of the coding machine 18 is pressed against the stop block 137 and clamped and positioned on the support plate 135 by the clamping mechanism 138.

[0053] The drive assembly 13 operates by driving the third motor 131 to rotate. It should be emphasized that the third motor 131 is a self-locking motor, meaning that its output end will not rotate when not powered. This self-locking motor can be a worm gear reducer motor or a stepper motor, which are existing mature technologies. It drives the third screw 132 to rotate. The driving bevel gear 133 at the end of the third screw 132 rotates and drives the driven bevel gear 134 to rotate, thereby driving the bidirectional screw 12 to rotate. While driving the two clamping plates 7 to move closer to each other to clamp the gas cylinder, the third screw 132 rotates and the connecting bar 136, the bearing plate 135, and the coding machine 18 move closer to the gas cylinder. Finally, while clamping the gas cylinder, the coding machine 18 also moves close to the gas cylinder. It should be noted that when the clamping plate 7 moves, its moving distance is the same as the moving distance of the coding machine 18.

[0054] When small gas cylinder manufacturing enterprises lack the resources to set up gas cylinder conveyor lines, the traditional coding machine 18 bracket cannot complete the coding work on the gas cylinders. In this case, the staff only needs to move the floor frame 1 to the gas cylinder to be coded. Then, the roller 9 can clamp the gas cylinder and automatically circle the gas cylinder, so that the coding machine 18 can circle the gas cylinder to perform the coding work. There is no need for the staff to hold the gas cylinder and circle it to perform the coding work, which greatly reduces the labor intensity of the gas cylinder coding work, saves manpower, and can clamp gas cylinders of various diameters to complete the coding work of gas cylinders of various diameters.

[0055] The clamping mechanism 138 includes a slide groove 1381 symmetrically opened on the support plate 135. A clamping block 1382 is slidably installed on the inner wall of the slide groove 1381. The clamping block 1382 is composed of an upper part 13821 and a lower part 13822 that are screwed together with screws. The connection between the upper part 13821 and the lower part 13822 slides in the slide groove 1381.

[0056] Rubber strips 1383 are fixed to the sides of the two clamping blocks 1382 that are close to each other. A drive column 1384 is fixed to the bottom of the clamping block 1382. A drive frame 1385 is symmetrically fixed to the top of the carrier box 51. The lower ends of the two drive columns 1384 are respectively inserted into the two drive frames 1385. The drive frame 1385 consists of a straight part 13851 and an inclined part 13852 connected to the straight part 13851.

[0057] When the two clamping plates 7 expand to their maximum distance, the bearing plate 135 is also moved to the top of the bearing box 51. Under the action of the drive frame 1385, the drive column 1384 reaches the inclined part 13852 of the drive frame 1385. The inclined part 13852 causes the two drive columns 1384 to move away from each other, thereby separating the rubber strip 1383 from the outer wall of the coding machine 18, releasing the state of clamping and fixing the coding machine 18. Then the coding machine 18 can be removed for maintenance and other work. When reinstalling, the coding machine 18 is placed on the bearing plate 135 in the state shown in the figure. One side of the coding machine 18 is against the outer wall of the stop block 137 and placed between the two rubber strips 1383. Then the bearing plate 135 moves, the two clamping plates 7 approach each other, and the two clamping blocks 1382 approach each other to clamp the coding machine 18.

[0058] By arranging the clamping mechanism 138, the coding machine 18 can be detachably mounted on the carrier plate 135, eliminating the need for manual disassembly and assembly between the coding machine 18 and the carrier plate 135. This further reduces manual operation steps and makes it more convenient to use. Furthermore, the clamping power is used to complete the clamping and fixing of the coding machine 18, reducing the investment in power equipment and reducing equipment manufacturing and operation and maintenance costs.

[0059] Example 2, please refer to Figure 11 and Figure 12 The difference between this embodiment and Embodiment 1 is that the carrier box 51 includes two adjusting discs 14 symmetrically rotatably connected to the outer wall of the carrier box 51 via bearings. The two sliding rods 6 are slidably connected to the two adjusting discs 14 via sliding holes, and the axis of the sliding rods 6 coincides with the axis of the adjusting discs 14. A synchronization bar 17 is fixed between the two adjusting discs 14. A limiting component is provided on the adjusting discs 14 to limit their movement. The limiting component includes a bolt 15 threadedly connected to the adjusting discs 14 via a threaded hole. Two insertion holes 16 are provided on both sides of the carrier box 51 where the adjusting discs 14 are installed, opposite to the adjusting discs 14. The bolts 15 cooperate with the insertion holes 16.

[0060] When the entire bracket is not in use and is stored, the bolt 15 can be rotated so that the bolt 15 rotates along the threaded hole and the end of the bolt 15 separates from the insertion hole 16. Then the clamping plate 7 can be flipped so that the two sliding rods 6 rotate. At this time, the third motor 131 does not work, and the bidirectional screw 12 and the third screw 132 remain stationary. Finally, the clamping plate 7 faces downward and the bolt 15 is aligned with the other insertion hole 16. The bolt 15 is rotated again and inserted into the insertion hole 16 to complete the positioning of the sliding rod 6 and the clamping plate 7. The folding of the entire bracket is completed, the overall volume is reduced, and it is easier to store.

[0061] Example 3, please refer to Figure 13 , Figure 14 and Figure 15 This embodiment provides another technical solution for the limiting component based on Embodiment 2: The limiting component includes a pin 19 slidably connected to the adjusting plate 14 through a sliding hole. A sleeve 20 is also fixed on the outer wall of the adjusting plate 14. The pin 19 is slidably connected to the end side wall of the sleeve 20. A retaining ring 191 is fixed on the outer wall of the inner part of the pin 19 in the sleeve 20. The retaining ring 191 is slidably connected to the inner wall of the sleeve 20. A spring 21 is sleeved on the outer side of the part of the pin 19 in the sleeve 20. One end of the spring 21 is in contact with the inner wall of the sleeve 20, and the other end of the spring 21 is in contact with the outer wall of the retaining ring 191. The side of the retaining ring 191 away from the spring 21 is pressed against the outer wall of the adjusting plate 14. Two locking holes 22 are opened on both sides of the carrier box 51 opposite to the adjusting plate 14. The pin 19 cooperates with the locking holes 22.

[0062] When the entire bracket is not in use and is stored folded, by simultaneously pulling the two pins 19 on both sides, the pins 19 slide along the inner wall of the sleeve 20 away from the carrier box 51. At this time, the sliding compression spring 21 is pressed, and the pin 19 is finally pulled out from the upper locking hole 22. This completes the unlocking of the two adjustment discs 14. Then, while holding the pin 19, slowly lower the pin 19 until the pin 19 is misaligned with the upper locking hole 22. Then, hold the clamp 7 and slowly lower it until the clamp 7 flips to face downwards, and the pin 19 is directly facing the lower locking hole 22. At this time, the spring 21 rebounds, pushing the locking ring 191 to slide and press against the outer wall of the adjustment disc 14 again, and the pin 19 inserts into the lower locking hole 22, completing the limiting work of the adjustment disc 14. In this way, the folding of the entire bracket is completed. The entire bracket can be folded when stored, reducing the storage space occupied, improving accessibility, and facilitating storage.

The bottom of the first screw (3) is fixed to the output end of the first motor (4). A lifting block (5) is slidably connected to the inner wall of the vertical frame (2). The lifting block (5) is threadedly connected to the first screw (3) via a threaded hole. The carrier box (51) is fixed on the lifting block (5). The entire coding machine bracket, after being equipped with the coding machine (18), can be used for coding of gas cylinders. It is suitable for coding gas cylinders when there is no gas cylinder conveyor line. In this case, the staff only needs to move the floor frame (1) to the gas cylinder to be coded. Then the four rollers (9) clamp the gas cylinder and automatically surround the gas cylinder so that the coding machine (18) surrounds the gas cylinder to perform coding work. There is no need for the staff to hold the gas cylinder and carry it around to perform coding work, which reduces the labor intensity of the gas cylinder coding work. The four rollers (9) can hold gas cylinders of different diameters. While holding gas cylinders of different diameters, the coding machine (18) can always maintain a certain distance from the outer wall of the gas cylinder. That is, while adjusting the distance between the two clamping plates, the position of the coding machine (18) can be adjusted synchronously. When the rollers (9) are clamped on the outer wall of the coding machine (18), the coding machine (18) is also adjusted to be close to the outer wall of the gas cylinder. There is no need to adjust after clamping. Instead, the position adjustment of the coding machine (18) is completed during the clamping process, saving operation time.

2. The coding machine bracket for seamless gas cylinder production according to claim 1, characterized in that: A rubber sleeve (10) is fixed on the outer wall of the roller (9).
