Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically to an auxiliary packaging device for stainless steel pipes. Background Technology

[0002] In the modern production process of stainless steel pipes, packaging is required to facilitate the transportation and use of stainless steel pipes. The most common packaging method used for packaging stainless steel pipes is bundling.

[0003] Currently, most packaging is done manually, which is time-consuming and labor-intensive. Automated packaging machines are also used. However, in the initial stage of automated bundling, manual pre-wrapping of the steel pipes is still required, which is cumbersome and inconvenient. Therefore, this case study was developed to address these issues. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary packaging device for stainless steel pipes, which can automatically pre-gather and pre-tie stainless steel pipes before packaging them through an automatic packaging machine.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stainless steel pipe auxiliary packaging device, including a packaging frame, characterized in that: a push conveyor belt is mounted on the packaging frame, a packaging machine is installed on the packaging frame at the tail end of the push conveyor belt, a binding and tensioning mechanism is provided at the upper side of the push conveyor belt away from the packaging machine, and a tensioning mechanism is also provided between the push conveyor belt and the packaging machine.

[0006] The strapping tensioning mechanism includes a strapping base, which is an orifice-shaped base composed of a top plate, a bottom plate, and vertical sections on both sides. A pusher seat is provided on the outer side of the strapping base on the pusher conveyor belt, which closes the outer side of the strapping base. The top plate, bottom plate, and any vertical section of the strapping base are respectively provided with C-shaped adjustment grooves. The adjustment grooves on both sides are staggered.

[0007] The chain expansion assembly includes a support base and a guide housing. The guide housing is located in the middle of the support base. A gear set is installed inside the binding guide housing. Sprockets are respectively installed on opposite sides of the binding guide housing. The sprockets on both sides are connected to the output end of the gear set. The two sprockets rotate relative to each other through the gear set. The upper ends of the two adjusting chains extend from the guide holes on the top plate of the binding base and mesh with the corresponding sprockets, and the lower ends are fixed in the adjusting groove.

[0008] In the above scheme: several guide rollers are evenly distributed in the lower middle part of a pair of adjustment chains.

[0009] In the above scheme: the conveyor belt is a chain plate type conveyor belt.

[0010] The stainless steel pipe auxiliary packaging device provided by this utility model has the following beneficial effects: This stainless steel pipe auxiliary packaging device realizes the automatic gathering of scattered steel pipes into bundles through chain cross-winding and dynamic tensioning technology, and then completes the bundling operation.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1

[0017] like Figs. 1-3 As shown, the stainless steel pipe auxiliary packaging device includes a packaging frame 1, which is a rectangular hollow shell. A push conveyor belt 4 is installed on the packaging frame. A packaging machine 3 is installed on the packaging frame 1 at the end of the push conveyor belt. The packaging machine 3 is a prior art vertical wrapping packaging machine. The packaging machine 3 uses stretch film to package the steel pipe. The packaging machine 3 is equipped with a packaging ring groove 2.

[0018] A strapping and tensioning mechanism 6 is provided at the upper end of the conveyor belt 4 away from the packaging machine 3. A tensioning mechanism 6 is also provided between the conveyor belt 4 and the packaging machine 3.

[0019] The binding tensioning mechanism 6 comprises a binding base 61 which is a mouth-shaped seat composed of a top plate, a bottom plate and vertical parts on both sides. The outer side of the binding base 61 on the advancing conveying belt 4 is provided with an advancing seat 5 which encloses the outer side of the binding base 61, the binding base 61 is arranged on the advancing conveying belt 4 and on the packaging frame 1 between the advancing conveying belt 4 and the packaging machine 3. The top plate, the bottom plate and each vertical part of the binding base 61 are respectively provided with a C-shaped adjusting groove 62, the adjusting grooves 62 on both sides are staggered, and adjusting chains 63 are respectively arranged in the adjusting grooves 62 on both sides. A binding control motor 64 is arranged on the top cross beam of the binding base 61, and a chain expansion and contraction assembly is connected to the driving end of the binding control motor 64. Preferably, the advancing conveying belt 4 is a chain plate type conveying belt.

[0020] The chain expansion and contraction assembly comprises a support seat 65 and a guide casing 66, the guide casing 66 is located in the middle of the upper side of the support seat 65, a gear set 68 is arranged in the guide casing 66, the gear set 68 is driven to operate by the binding control motor, chain wheels 67 are respectively arranged on the opposite sides of the guide casing 66, the chain wheels 67 on both sides are respectively connected with the output ends of the gear set 68, and the two chain wheels 67 are relatively rotated through the gear set 68. The upper ends of the two adjusting chains 63 are extended from the guide holes in the top plate of the binding base 61 and engaged with the corresponding chain wheels 67, and the lower ends are fixed in the adjusting grooves 62. The support seat 65 supports the adjusting chains 63.

[0021] The middle and lower sections of the adjusting chains 63 are uniformly provided with a plurality of guide rollers 69.

[0022] When the worker places the unbound steel pipe on the advancing conveying belt (of course, an automatic conveying structure can be arranged to convey the unbound steel pipe to the advancing conveying belt), the advancing conveying belt conveys one end of the unbound steel pipe into the tensioning mechanism 6 between the advancing conveying belt 4 and the packaging machine 3. The adjusting chains 63 on both sides of the binding base 61 are in parallel in the initial state (as shown in Fig. 2 and 3 When the binding control motor 64 drives the gear set 68 to make the double chain wheels 67 rotate reversely, the adjusting chains 63 pass through the guide holes in which nylon bushings are inlaid, and the upper ends of the two adjusting chains form a cross winding track. During the crossing process, the chain tension gradually increases to force the adjusting chains to come out of the adjusting grooves, so that the scattered steel pipes are automatically gathered into a regular pipe bundle in the advancing process.

[0023] This process is synchronized with the tensioning mechanism of the advancing seat 5 to form a bidirectional constraint, which ensures that the pipe bundle maintains a tight state when entering the packaging ring groove 2, and the film winding is directly completed by the vertical ring packaging machine (such as the Hongyunlai HDB-201 high platform unmanned binding and packaging machine and the Shanghai Douxuan steel pipe winding packaging machine. The above binding and packaging are prior art and will not be described here).

[0024] The guide hole on the bundling base 61 adopts a trumpet tapering design, facilitating chain installation, and the tensioning mechanism near the advancing base 5 is synchronously controlled, so that the front and rear ends of the pipe bundle simultaneously bear symmetrical folding force, avoiding the pipe from being scattered during advancing.

[0025] The guide roller adopts a rubber roller, which forms rolling contact with the surface of the steel pipe during advancing, reducing chain wear and preventing pipe body scratching.

[0026] The chain plate type advancing conveying belt 4 and the advancing base 5 are connected in a modular manner, the dovetail groove arranged on the bottom surface of the advancing base 5 is matched with the chain plate key, and the distance between the two sets of tensioning mechanisms can be quickly adjusted according to the length of the steel pipe.

[0027] After the packaging is completed, the sprocket 67 rotates forward, so that the adjusting chain 63 returns to the adjusting groove 62. During the returning process of the adjusting chain, the part of the adjusting chain on the bottom plate will automatically return to the adjusting groove 62 on the bottom plate under the action of gravity due to the fixed lower end in the adjusting groove 62, and the vertical part and the top plate part can not return or can be manually assisted to return without returning.

[0028] The stainless steel pipe auxiliary packaging device realizes automatic folding and bundling integration of scattered steel pipes through cross winding of chains and dynamic tensioning technology. The chains cross the pipe bundle under the drive of the motor, forming a centripetal folding force field. The front and rear synchronous tensioning mechanisms ensure that the pipe bundle in a tight state enters the winding work station, completely replacing the manual pre-bundling link, significantly improving the packaging efficiency and reducing the labor intensity.

[0029] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
