Description

Technical Field

[0001] This utility model relates to the field of packing machine technology, and in particular to a packing strap lateral straightening device. Background Technology

[0002] Fully automatic baling machines are widely used in thin slab continuous casting and rolling production lines. When the coiled baling tape is used on the baling machine, it first needs to pass through its own straightening device to restore the curled baling tape to its original straight state so that it can automatically complete the winding into a whole loop in the guide groove guard plate of the baling machine.

[0003] Currently, the straightening devices built into packaging machines on the market are only effective in the horizontal length direction. However, there is no corresponding mechanism to deal with the horizontal bending (sickle bend). Excessive sickle bends often cause the strapping to go out of the groove or get stuck during the strapping process. This is one of the main reasons why the strapping cannot be automatically completed, which seriously restricts the packaging rhythm and increases the intensity of manual maintenance.

[0004] Therefore, it is necessary to propose a lateral straightening device for packing straps to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0005] The main purpose of this utility model is to provide a lateral straightening device for packing straps, so as to solve the problem that the packing straps in the prior art cannot cope with horizontal lateral straightening, resulting in the strapping getting stuck.

[0007] The straightening mechanism has a straightening channel extending longitudinally for the packing strap to pass through. The straightening mechanism has multiple blind holes spaced longitudinally on both sides along the transverse direction. Each blind hole is connected to a guide wheel, which is rotatably mounted and used to abut against the packing strap.

[0008] The straightening mechanism is also provided with an installation groove on one side, which is connected to the straightening channel.

The first end of the lateral adjustment screw passes through the top of the rocker arm and extends into the base to drive the top of the rocker arm to swing around the bottom pin for adjustment. The second end of the lateral adjustment screw extends out of the base.

[0011] Preferably, the mounting groove is arc-shaped at the center of the side facing the packing strap.

[0012] Preferably, two guide wheels are provided on the base at positions that are laterally opposite to the mounting groove.

[0013] Preferably, it further includes an adjusting handwheel, which is connected to the second end of the lateral adjusting screw.

[0035] Please see the appendix Figure 1-6This utility model provides a lateral straightening device for a packing strap 40, comprising a straightening mechanism 10, a lateral adjustment component 20, and multiple guide wheels 30. First, it should be noted that in this application, "lateral" refers to the width direction of the base 110, and "longitudinal" refers to the length direction of the base 110, as shown in the accompanying drawings. Unlike existing straightening devices in packing machines, which are limited to straightening in the horizontal length direction, this device completely lacks a corresponding mechanism to handle horizontal bends (sickle bends). Excessive sickle bends often cause the strapping strap to slip out of its groove or become stuck during threading, which is one of the main reasons why the strapping strap cannot be threaded automatically, severely restricting the packing pace and increasing the intensity of manual maintenance. This application solves the above-mentioned defects in the prior art by providing a lateral straightening device for the packing strap, as detailed below:

[0036] The straightening mechanism 10 has a straightening channel 111 extending longitudinally, through which the packing strap 40 passes. The straightening mechanism 10 has multiple blind holes spaced longitudinally on both sides along the transverse direction. Each blind hole is connected to a guide wheel 30, which is rotatably mounted and used to abut against the packing strap 40. A mounting groove 112 is also provided on one side of the straightening mechanism 10, communicating with the straightening channel 111. A guide wheel 30 is connected to the transverse adjustment component 20, which is movably connected to the mounting groove 112 along the transverse direction.

[0037] Specifically, the lateral straightening device for the packing strap 40 in this application includes a straightening mechanism 10, a lateral adjustment component 20, and multiple guide wheels 30. The straightening mechanism 10 is used for the packing strap 40 to pass through in order to achieve the purpose of straightening. Therefore, the straightening mechanism 10 has a straightening channel 111 that extends longitudinally. The guide wheels 30 serve two purposes: firstly, as rolling guides to reduce the frictional resistance increased during the straightening process; secondly, after the lateral adjustment is performed, the guide wheels 30 installed on the lateral adjustment component 20 change the distance between the guide wheels 30 on both sides to achieve the effect of lateral straightening.

[0038] Except for the guide wheel 30 on the lateral adjustment assembly 20, the other guide wheels 30 are all installed and connected via blind holes on both sides of the straightening mechanism 10 along the lateral direction. They are connected by pins to maintain their rotation and are connected to the packing strap 40 to act as rolling guides and reduce friction. For lateral straightening, the guide wheels 30 on the lateral adjustment assembly 20 need to be adjusted. Therefore, a mounting groove 112 is also provided on one side of the straightening mechanism 10. The mounting groove 112 is used for installing the lateral adjustment assembly 20, allowing the lateral adjustment assembly 20 to be movably connected to the mounting groove 112 along the lateral direction. When the lateral adjustment component 20 is adjusted to move laterally, the guide wheel 30 on the lateral adjustment component 20 moves laterally accordingly. As a result, the distance between the adjustable guide wheel 30 and the guide wheel 30 on the other side changes. When the distance is adjusted to a suitable position, it is the position for straightening work, so as to straighten the sickle-shaped packing strap 40. It can be understood that the back of the sickle (i.e., the protruding side) should face the lateral adjustment component 20 to ensure a better straightening effect. If it is not aligned in this way during the straightening process, it can be removed, flipped, and re-threaded so that the position of the sickle-shaped back of the strap can be straightened by the guide wheel 30 on the lateral adjustment component 20.

[0039] In a preferred embodiment of the present invention, the straightening mechanism 10 includes a base 110 and a cover plate 120. The cover plate 120 is connected to the base 110. The middle part of the base 110 is recessed longitudinally to form the straightening channel 111 with the cover plate 120. The blind hole and the mounting groove 112 are also recessed on both sides of the base 110, respectively.

[0040] It should be noted that the base 110 is the main supporting body of the entire device and is used for the installation of various components. Therefore, various recesses are formed on the base 110, such as blind holes for the installation of guide wheels 30 and mounting grooves 112 for the installation of lateral adjustment components 20. The longitudinally recessed part of the base 110 cooperates with the cover plate 120 to form the straightening channel 111. The cover plate 120 can also limit the depth range of the straightening channel 111 to ensure that the packing strap 40 does not warp along the thickness direction during lateral straightening. Preferably, the cover plate 120 is installed on the base 110 by bolt connection to facilitate easy disassembly and installation, convenient assembly and replacement of internal components, and easy processing.

[0041] In a preferred embodiment of this utility model, the lateral adjustment assembly 20 includes a rocker arm 210 and a lateral adjustment screw 220. The rocker arm 210 is disposed in the mounting groove 112, and a groove is formed in the middle of the rocker arm 210. A guide wheel 30 is connected to the groove. The bottom of the rocker arm 210 is hinged to the base 110 by a pin. The first end of the lateral adjustment screw 220 passes through the top of the rocker arm 210 and extends into the base 110 to drive the top of the rocker arm 210 to swing and adjust around the bottom pin. The second end of the lateral adjustment screw 220 extends out of the base 110.

[0042] It should be noted that the rocker arm 210 is used to mount a guide wheel 30, which is set in the mounting groove 112. The recess formed near the middle position is used to mount the guide wheel 30. The bottom of the rocker arm 210 is hinged by a pin to allow it to swing around this pin during adjustment, thereby driving the middle guide wheel 30 to swing towards the packing strap 40, thus adjusting the distance between it and the guide wheel 30 on the other side. The top of the rocker arm 210 is adjusted by tightening and loosening the lateral adjusting screw 220. When the lateral adjusting screw 220 is tightened, it drives the rocker arm 210 to swing around the bottom pin towards the packing strap 40, and the guide wheel 30 swings towards the packing strap 40 accordingly. When the lateral adjusting screw 220 is loosened, the opposite occurs.

[0043] In a preferred embodiment of the present invention, the mounting groove 112 is arc-shaped in the middle of the side facing the packing strap 40.

[0044] It is worth noting that the arc shape facilitates the swing of the guide wheel 30 on the rocker arm 210 to move in and out, so as to be close to the packing strap 40 for straightening.

[0045] In a preferred embodiment of the present invention, two guide wheels 30 are provided on the base 110 at positions that are laterally opposite to the mounting groove 112.

[0046] It is worth noting that two guide wheels 30 are provided at positions on the other side corresponding to the mounting groove 112 in the lateral direction to cooperate with the guide wheels 30 on the rocker arm 210 for lateral straightening. As the distance between the guide wheels 30 on the rocker arm 210 and these two guide wheels 30 decreases, the distance size for compression straightening is gradually reached. The guide wheels 30 in other positions remain in place and are only used for rolling guidance to reduce frictional resistance.

[0047] Furthermore, it also includes an adjusting handwheel 230, which is connected to the second end of the transverse adjusting screw 220.

[0048] It should be noted that the adjusting handwheel 230 is easy for technicians to operate, so as to tighten or loosen the lateral adjusting screw 220 by rotating the adjusting handwheel 230.

[0049] Furthermore, it also includes a limiting pin 240, and the adjusting handwheel 230 has a plurality of limiting holes 231 arranged at intervals along the circumference; wherein,

[0050] The base 110 has a limiting channel extending laterally. The limiting pin 240 passes through the limiting channel and extends out at both ends. The first end of the limiting pin 240 is U-shaped and is inserted into the limiting hole 231. The second end of the limiting pin 240 is connected to the nut.

[0051] It should be understood that the limiting pin 240 is used to limit the rotation of the lateral limiting screw. When the distance between the guide wheel 30 on the rocker arm 210 and the two guide wheels 30 on the other side reaches the target ideal position, the limiting pin 240 can be used to prevent self-rotation and thus avoid errors. Therefore, multiple limiting holes 231 are provided on the adjusting handwheel 230 at intervals along the circumference. The limiting holes 231 are used to cooperate with the limiting pin 240. The first end of the limiting pin 240 is U-shaped to facilitate insertion into the limiting hole 231, while the second end of the limiting pin 240 has external threads, which are tightened by a nut to achieve a secure installation. Preferably, the number of limiting holes 231 on the adjusting handwheel 230 is eight. The number can be set according to the size of the limiting holes 231 and the adjacent spacing to determine different interval positions for each adjustment. Those skilled in the art can select according to actual needs.

[0052] Furthermore, it also includes a compression spring 250. A countersunk hole communicating with the limiting channel is formed in the second end of the base 110 near the limiting pin 240. The compression spring 250 is sleeved on the second end of the limiting pin 240 and disposed in the countersunk hole.

[0053] It should be noted that the compression spring 250 is used to provide a preload to prevent the limiting pin 240 from disengaging and failing when it is inserted and hooked into the limit.

[0054] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
