[0032] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0036] Please see the appendix Figure 1-6 This utility model provides a straightening mechanism for a baling machine, comprising a straightening component 10 and an eccentric adjustment component 20. First, it should be noted that in this application, "lateral" refers to the width direction along the base 110. Unlike existing technologies that typically involve disassembling the entire straightening machine assembly offline for processing and then reassembling, requiring space for the rolls to mitigate heat radiation damage and severely restricting production speed; alternatively, online adjustment can be used, but online disassembly requires extensive disassembly work, and reassembly is cumbersome, resulting in a time-consuming and labor-intensive process with low maintenance efficiency. This application addresses the aforementioned deficiencies in the prior art by providing a straightening mechanism for a baling machine, as detailed below:

[0037] The straightening assembly 10 includes a base 110, a first cover plate 120, and a second cover plate 130. The base 110 includes a first straightening part 111 and a second straightening part 114. The first straightening part 111 has a first slot 112. The first cover plate 120 has a protruding first locking block 121 that matches the first slot 112. The first locking block 121 is engaged in the first slot 112, and the first cover plate 120 is detachably connected to the first straightening part 111 by bolts. The middle of the first straightening part 111 is recessed to form a first straightening channel 113 with the first cover plate 120. The second straightening part 114 has a second slot 115, and the second cover plate 130 has a protruding second slot 115 that matches the second slot 115. A matching second locking block 131 is engaged in the second locking slot 115, and the second cover plate 130 is detachably connected to the second straightening part 114 by bolts. The middle part of the second straightening part 114 is recessed to form a second straightening channel 116 with the second cover plate 130. The first cover plate 120 and the second cover plate 130 are spaced apart to form an adjustment space. The eccentric adjustment assembly 20 includes a drive connection part 210 and an eccentric adjustment part 220. The drive connection part 210 is connected to the middle part of the base 110, and the eccentric adjustment part 220 is connected to the drive connection part 210 and disposed in the adjustment space. The eccentric adjustment part 220 is spaced apart from the base 110 and is eccentrically rotatable.

[0038] Specifically, the straightening mechanism of the packing machine in this application includes a straightening component 10 and an eccentric adjustment component 20. The straightening component 10 is used to straighten the warped packing strap and includes a base 110, a first cover plate 120, and a second cover plate 130. The base 110 is divided into a first straightening section 111 and a second straightening section 114. The first straightening section 111 has a recessed middle setting to form a first straightening channel 113 with the first cover plate 120, and the second straightening section 114 has a recessed middle setting to form a second straightening channel 116 with the second cover plate 130. Both are used to straighten the packing strap. Therefore, the first straightening channel 113 and the second straightening channel 116 are on the same extension axis. When the packing strap comes out of the first straightening channel 113, it is further squeezed and straightened by the eccentric adjustment component 20 before entering the second straightening channel 116. Therefore, the eccentric adjustment component 20 is disposed between the first cover plate 120 and the second cover plate 130.

[0039] The first straightening section 111 has a first slot 112, and the first cover plate 120 has a first locking block 121 that matches the first slot 112. This interlocking structure is formed by the locking connection to strengthen the connection. With the bolts for fastening, it is ensured that the packing strap will not fall off during straightening. In case of a strap jamming, the bolts need only be removed and the first locking block 121 of the first cover plate 120 needs to be moved to disengage from the first slot 112 to remove the first cover plate 120. This allows for online troubleshooting of the packing strap jammed in the first straightening channel 113. The process is very convenient and quick, eliminating a lot of disassembly work and greatly shortening the troubleshooting process. The second slot 115 of the second straightening section 114 and the second locking block 131 of the second cover plate 130 have the same structural form as the first slot 112 and the first locking block 121, so they will not be described in detail here. Please refer to the first slot 112 and the first locking block 121 for details.

[0040] Furthermore, the first cover plate 120 and the second cover plate 130 are spaced apart to form an adjustment space, which is used for the eccentric adjustment assembly 20. The eccentric adjustment assembly 20 includes a drive connection part 210 and an eccentric adjustment part 220. The drive connection part 210 is used for the installation of the eccentric adjustment part 220, so that after the eccentric adjustment part 220 is installed, it can be located in the adjustment space and driven to rotate. The eccentric adjustment part 220 itself can rotate eccentrically. Thus, after the eccentric adjustment part 220 is driven to rotate eccentrically by the drive connection part 210, the distance between it and the base 110 is adjusted, thereby adjusting the straightening effect.

[0041] In a preferred embodiment of the present invention, the first straightening part 111 has a plurality of first slots 112 on both sides of the transverse direction, and the first slots 112 on each side of the first straightening part 111 are spaced apart along the extension direction of the first straightening part 111; the second straightening part 114 has a plurality of second slots 115 on both sides of the transverse direction, and the second slots 115 on each side of the second straightening part 114 are spaced apart along the extension direction of the second straightening part 114.

[0042] It should be noted that this arrangement provides slots on both sides of the first straightening part 111 and the second straightening part 114. Similarly, the first cover plate 120 and the second cover plate 130 are also provided with first locking blocks 121 and second locking blocks 131 on both sides, thus ensuring that both sides are connected by locking, making the connection more stable and uniform. Preferably, there are three on each side to ensure uniform distribution at both ends and in the middle. The specific number can be set by those skilled in the art as needed.

[0043] In a preferred embodiment of the present invention, both the first card slot 112 and the second card slot 115 are arranged in an inclined manner.

[0044] It should be noted that the inclined setting makes the matching fit more secure during connection, so as to have a vertical limiting ability when the entire device is placed horizontally; and in a preferred embodiment of the present invention, the first slot 112 and the second slot 115 are respectively inclined toward the end away from the eccentric adjustment component 20, so that during disassembly, the first cover plate 120 and the second cover plate 130 can be separated by moving them a small distance toward the eccentric adjustment component 20 respectively.

[0045] In a preferred embodiment of the present invention, the drive connection part 210 includes a drive gear 211, a transmission gear 212, and two side plates 213. The two side plates 213 are laterally connected to the two sides of the middle part of the base 110. The drive gear 211 and the transmission gear 212 are rotatably connected to one side plate 213, and the drive gear 211 and the transmission gear 212 are meshed. The eccentric adjustment part 220 is eccentrically rotatably connected between the two side plates 213, and one end of the eccentric adjustment part 220 is connected to the transmission gear 212.

[0046] It is worth noting that the side plate 213 is used for mounting the drive gear 211 and the transmission gear 212. The two side plates 213 facilitate the installation of the eccentric connection part. The two side plates 213 are connected laterally to the two sides of the middle part of the base 110 so that the eccentric connection part can be located in the adjustment space when it is installed. The drive gear 211 serves as a drive source. Technicians drive the drive gear 211 to rotate so as to drive the transmission gear 212 to rotate through gear meshing. The eccentric adjustment part 220 connected to the transmission gear 212 realizes its own eccentric rotation.

[0047] Furthermore, the eccentric connection includes a rotating shaft 221 and an eccentric wheel 222. The rotating shaft 221 is rotatably connected between the two side plates 213, and one end of the rotating shaft 221 extends out of one side plate 213 and is connected to the transmission gear 212. The eccentric wheel 222 is eccentrically connected to the rotating shaft 221 and is spaced apart from the base 110.

[0048] It should be noted that the rotating shaft 221 is used to mount and rotate the eccentric wheel 222. It is connected between the two side plates 213 and one end extends out so that the transmission gear 212 can be sleeved on one end of the rotating shaft 221. The eccentric wheel 222 is eccentrically mounted on the rotating shaft 221. Thus, when the rotating shaft 221 rotates, the eccentric wheel 222 rotates eccentrically. The distance between the eccentric wheel 222 and the base 110 changes according to its position after eccentric rotation, thereby adjusting the straightening effect.

[0049] Furthermore, the eccentric connection portion also includes a spacer 223, which is connected between the eccentric wheel 222 and the side plate 213.

[0050] It should be understood that the spacer 223 is used to prevent the eccentric wheel 222 from moving axially, and therefore it is connected between the eccentric wheel 222 and the side plate 213.

[0051] Furthermore, it also includes a locking pin 214. The side plate 213 has a blind mounting hole. The locking pin 214 is connected to the blind mounting hole and is disposed between the teeth of the drive gear 211. The locking pin 214 is provided to extend and retract laterally.

[0052] It should be noted that the locking pin 214 is used to limit the eccentric position of the eccentric wheel 222 after it has been determined, so as to prevent the eccentric wheel 222 from rotating off course. Therefore, a blind hole extending laterally is provided on the side plate 213 (the side plate 213 on which the drive gear 211 is installed) for the locking pin 214 to be installed in the blind hole. The locking pin 214 needs to be set between the teeth of the drive gear 211 to achieve the limiting effect. Preferably, two locking pins 214 can be set to ensure better limiting performance. It can be understood that the locking pin 214 is set to be retractable laterally to ensure that it has a limiting function when extended, while it can ensure the normal rotation of the drive gear 211 when it is retracted into the blind hole.

[0053] Furthermore, it also includes a spring 215, which is sleeved on the locking pin 214 and built into the mounting blind hole.

[0054] It should be noted that the spring 215 provides a self-recovering capability for the extension and retraction adjustment of the locking pin 214. Thus, when the drive gear 211 needs to be rotated for adjustment, the locking pin 214 can be pressed down. In normal state, the locking pin 214 will spring back and extend out of the mounting blind hole under the action of the elastic force, thereby setting between the teeth of the drive gear 211 for limiting.

[0055] 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.
