Description

Technical Field

[0001] This utility model relates to the field of metal processing machinery, and in particular to a steel strip support device for the production of thermos cup tubes. Background Technology

[0002] As a widely used container in daily life, the core heat preservation performance of a thermos cup largely depends on the vacuum layer formed between the inner liner and the outer wall. The cup tube, as a key component constituting the main body of this vacuum layer, is usually made of stainless steel strip.

[0003] In existing technologies, the forming of insulated cup tubes mainly relies on multi-station roll forming machines. In this equipment, a steel strip is continuously fed in and passes through a series of precisely designed forming dies. These dies, through multiple passes of progressive extrusion and bending, cause the two edges of the steel strip to gradually curl and converge towards the center line, ultimately forming a closed circular or shaped tube near the exit end. The joined seam is then continuously welded by welding equipment to form a strong weld, producing a continuous steel tube. After forming and welding, the steel tube is cut to a fixed length by a subsequent cutting device to obtain individual cup tubes.

[0004] However, during the steel pipe cutting process, to ensure cutting accuracy and operational safety, the steel pipe must be temporarily stopped, while the uncoiling, leveling, and bending processes of the steel strip at the front end of the forming and welding unit are usually continuous. This condition, where the steel pipe is stationary while the front end of the steel strip is continuously fed, results in a section of steel strip suspended between the uncoiling device and the feed inlet of the forming unit. This suspended steel strip will inevitably undergo downward bending deformation under its own weight. More importantly, as the diameter of the steel coil decreases during production, from a full coil to an empty coil, the position of the coil's discharge point changes significantly, causing the length of this suspended steel strip to fluctuate continuously. During each cutting pause, the accumulated bending deformation of this constantly changing length of suspended steel strip also varies. This intermittent and irregular accumulation of bending deformation will adversely affect the initial posture and tension stability of the steel strip entering the forming unit, potentially leading to decreased forming accuracy, fluctuations in weld quality, and even problems such as belt slippage and jamming. Utility Model Content

[0005] The technical problem to be solved by this utility model is the accumulation of bending deformation in the suspended section. It provides a steel strip support device for the production of thermos cup tubes, aiming to solve the above-mentioned problem.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a steel strip support device for the production of thermos cup tubes, including a support frame, an unwinding roller, a connecting block, a moving block, a guide rod, a return spring, and an adjustment component. Guide rods are connected to both the left and right sides of the support frame, and moving blocks are slidably connected to the guide rods. The moving blocks are slidably connected to the side plates of the support frame. Connecting blocks are connected to both the left and right ends of the unwinding roller, and the connecting blocks are rotatably connected to the moving blocks. A return spring is sleeved on the guide rod, the top of the return spring is connected to the moving block, and the bottom of the return spring is connected to the support frame. An adjustment component for adjusting the height of the support frame is provided at the bottom of the support frame.

[0007] A further preferred embodiment of this utility model is as follows: the adjustment assembly includes a fixed ring, an adjustment rod, a bolt rod, and a support plate. Fixed rings are connected to the four corners of the bottom of the support frame. Two adjustment rods are connected to the top of the support plate. The adjustment rods pass through the support frame and are slidably connected to the fixed rings. Several slots are opened on the adjustment rods. Bolt rods are slidably connected to the side of the fixed rings. The bolt rods are limited and engaged with the adjustment rods through the slots. The length of the support plate is greater than the width of the support frame.

[0008] A further preferred embodiment of this utility model is: it also includes a motor and a brush, with the motor mounted on the top of the support frame, the brush rotatably connected to the top of the support frame, and the end of the brush connected to the output shaft of the motor.

[0009] A further preferred embodiment of this utility model is: it also includes a limiting plate, the side of the fixing ring is connected to the limiting plate, and the limiting plate is in a limiting cooperation with the bolt rod.

[0010] A further preferred embodiment of this utility model is that the side of the adjusting rod has several marking grooves.

[0011] A further preferred embodiment of this utility model is: it also includes stabilizing feet, and the bottom of the support plate is connected to several stabilizing feet.

[0012] A further preferred embodiment of this utility model is: it also includes a guide plate, and the guide plate is connected to the upper front side of the support frame.

[0013] A further preferred embodiment of this utility model is: it also includes a protective shell, with the protective shell connected to the left and right sides of the upper part of the support frame, and the movable block slidably connected inside the protective shell.

[0014] Compared with the prior art, the advantages of this utility model are as follows: Through the cooperation of the unwinding roller, connecting block, moving block, guide rod, and return spring, the weight of the steel coil compresses the return spring when it presses down on the moving block, and when the diameter of the steel coil decreases, the return spring rebounds, pushing the moving block upwards along the guide rod. This achieves automatic height adjustment of the unwinding roller according to the change in the steel coil diameter, maintaining a stable relative height between the steel strip discharge point and the subsequent equipment feed point. Through the mechanical linkage of the adjusting rod, fixing ring, bolt, and clamp, workers can, with the assistance of lifting equipment, pull out the bolt to release the limit, allowing for the overall lifting and lowering of the support frame and guide plate height. After adjustment, inserting the bolt to lock the clamp enables precise adjustment of the suspended section support height, quickly correcting excessive steel strip sag and eliminating accumulated bending deformation. The motor-driven brush rotation causes the steel strip to be brushed at high speed before passing the guide plate, automatically removing surface impurities. The guide plate constrains the steel strip discharge path and protects the outer shell from external interference, ultimately ensuring the steel strip enters the forming equipment in a clean and straight state.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the structure of the steel strip support device, as follows:

[0024] A steel strip support device for the production of thermos cup tubes, such as Figures 1-4 As shown, the support frame includes a support frame 1, an unwinding roller 2, a connecting block 3, a moving block 4, a guide rod 5, a return spring 6, and an adjustment assembly. Guide rods 5 are connected to both the left and right sides of the support frame 1. Moving blocks 4 are slidably connected to the guide rods 5 and are slidably connected to the side plates of the support frame 1. Connecting blocks 3 are connected to both the left and right ends of the unwinding roller 2 and are rotatably connected to the moving blocks 4. A return spring 6 is sleeved on the guide rod 5. The top of the return spring 6 is connected to the moving block 4, and the bottom of the return spring 6 is connected to the support frame 1. An adjustment assembly for adjusting the height of the support frame 1 is provided at the bottom of the support frame 1.

[0025] like Figure 1 and Figure 4 As shown, the adjustment assembly includes a fixing ring 7, an adjusting rod 8, a bolt 9, and a support plate 10. The four corners of the bottom of the support frame 1 are connected to the fixing ring 7. Each support plate 10 is connected to two adjusting rods 8 at the top. The four adjusting rods 8 pass through the support frame 1 and are slidably connected to the fixing ring 7. Each adjusting rod 8 has several slots 81. The bolt 9 is slidably connected to the side of the fixing ring 7. The bolt 9 is limited and engaged with the adjusting rod 8 through the slots 81. The length of the support plate 10 is greater than the width of the support frame 1, providing a wider support surface and enhancing the stability of the adjustment assembly and the bottom of the entire device.

[0026] like Figure 1 As shown, it also includes a motor 11 and a brush 12. The motor 11 is mounted on the top of the support frame 1, and the brush 12 is rotatably connected to the top of the support frame 1. The end of the brush 12 is connected to the output shaft of the motor 11.

[0027] like Figure 1 and Figure 4 As shown, it also includes a limiting plate 13, and the side of the fixing ring 7 is connected to the limiting plate 13, which is in a limiting fit with the bolt rod 9.

[0028] like Figure 4 As shown, the side of the adjusting rod 8 has several marking slots 14, which provide a reference position for height adjustment.

[0029] like Figure 1 As shown, it also includes stabilizing feet 15. Each support plate 10 has two stabilizing feet 15 connected to its bottom, which increases the contact area between the equipment and the ground, provides stable support, prevents the equipment from shaking or overturning when it is running or adjusting its height, and ensures overall stability.

[0030] like Figure 1 As shown, it also includes a guide plate 16. The upper front side of the support frame 1 is connected to the guide plate 16, which is used to precisely guide the steel strip from the unwinding mechanism to smoothly and centrally enter the subsequent processing equipment.

[0031] like Figure 1 As shown, it also includes a protective shell 17. The protective shell 17 is connected to the left and right sides of the upper part of the support frame 1. The moving block 4 is slidably connected inside the protective shell 17. The protective shell 17 mainly wraps around and protects key moving parts such as the moving block 4, guide rod 5, and return spring 6, preventing the intrusion of foreign objects, accidental contact by personnel, and splashing of lubricating grease, thereby improving the safety and reliability of equipment operation.

[0032] Workers hoist the coiled steel strip onto the unwinding roller 2 of the device. The weight of the steel coil is transferred through the unwinding roller 2 to the connecting blocks 3, which are rotatably connected to its two ends. The connecting blocks 3 then transfer the force to the movable blocks 4 connected to them, causing the movable blocks 4 to overcome the elastic force of the return spring 6 and slide downwards along the vertically fixed guide rod 5 and the side plate of the support frame 1. At the same time, the return spring 6 is compressed by the movable blocks 4, storing elastic potential energy. The steel strip is drawn out from the steel coil, passes through the middle of the guide plate 16 above the front of the support frame 1, and enters the subsequent bending and welding equipment.

[0033] As production progresses, the steel strip is continuously drawn from the coil, the coil diameter gradually decreases, and the position of the steel strip from the discharge point of the coil continuously rises. At this time, the elastic potential energy stored in the return spring 6 begins to be released, pushing the moving block 4 to slide upward along the guide rod 5 and the side plate of the support frame 1. The moving block 4 drives the unwinding roller 2 to move upward synchronously through the connecting block 3. This automatic lifting process ensures that the unwinding roller 2 can always adjust its height according to the change in the coil diameter, keeping the path of the steel strip from the coil to the guide plate 16 as straight as possible, reducing additional bending or tension fluctuations in the steel strip caused by changes in the discharge point height, thereby balancing the impact of changes in the coil diameter on subsequent continuous processing.

[0034] When subsequent processes cause the steel strip conveying to pause, while the unwinding end is still discharging material, the suspended section of the steel strip between the unwinding roller 2 and the guide plate 16 may experience excessive bending and sagging due to gravity. At this time, the operator uses lifting equipment to support the entire support frame 1. Subsequently, the operator manually pulls out the bolts 9 installed on the side of the fixing ring 7 one by one. During the pulling out of the bolts 9, the ends of the bolts 9 are restrained by the limiting plate 13, ensuring that the bolts 9 do not completely detach from the fixing ring 7. After all four bolts 9 are pulled out from the latches 81 on the adjusting rod 8, the limiting between the adjusting rod 8 and the fixing ring 7 is released. At this time, the operator uses lifting equipment to raise or lower the overall height of the support frame 1. The support frame 1 moves the fixing ring 7, guide plate 16, unwinding roller 2, and related components together, thereby changing the support point height of the suspended steel strip until the steel strip returns to a straight state, eliminating excessive bending and sagging. As the support frame 1 moves, the adjusting rod 8 slides within the fixing ring 7.

[0035] After adjusting the support frame 1 to the desired height, the operator needs to relock the height. Before inserting the bolt 9, ensure that the specific marking groove 14 on the adjusting rod 8 is approximately aligned with the upper end face of the fixing ring 7. Then, the operator pushes the bolt 9 back into the groove of the fixing ring 7, so that the end of the bolt 9 inserts into the corresponding slot 81 on the adjusting rod 8 at the current height. The bolt 9 securely locks the adjusting rod 8 into the fixing ring 7 through the slot 81, preventing relative sliding and thus fixing the support frame 1 at the new height position. The limiting plate 13 prevents the bolt 9 from accidentally slipping out.

[0036] After the steel strip is drawn from the steel coil and before entering the guide plate 16, the surface of the steel strip undergoes a cleaning process. A motor 11 mounted on top of the support frame 1 drives a brush 12 connected to its output shaft to rotate at high speed. The rotating brush 12 contacts the surface of the passing steel strip, brushing away dust, oil, debris, and other impurities, thus providing a clean raw material surface for subsequent critical processes such as bending and welding, and helping to ensure product quality.
