[0002] With the development of industrial automation, more and more industries are embracing automated production. The packaging of products such as flour, feed, and chemical raw materials is also gradually adopting automated packaging production. Automated production speeds up the efficiency of bag closing and shortens process time.

[0003] In the specific process flow, during this section of transportation, due to inertia and the open posture of the packaging bag, the material in the packaging bag is in a loose state. When reaching the folding machine, the material in the packaging bag gradually settles, and the packaging bag will become skewed or even tilted. In the automated production process, the straightening mechanism is not set, causing the packaging bag mouth to deviate from the working straight line position, affecting the automated processing accuracy of the packaging bag. Therefore, it is necessary to set a holding and straightening component on the packaging bag so that the packaging bag can be transported normally. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 1-2 , is the first embodiment of the utility model, which provides a packaging bag holding mechanism for an automatic packaging machine, comprising:

[0028] The support assembly 100 includes a base 101, a slide 102 is fixedly connected to the upper surface of the base 101, and the slide 102 is provided with a driving assembly 200;

[0029] In addition, the driving assembly 200 includes a coupling 203 fixedly connected to the top of the base 101, a pen-shaped cylinder 201 is fixedly passed through the outer surface of the coupling 203, the output end of the pen-shaped cylinder 201 is fixedly connected to a straight shaft 204, the end face of the straight shaft 204 is fixedly connected to a polygonal rack 301, the teeth of the polygonal rack 301 are engaged with a spur gear 302, the spur gear 302 is cooperated with a primary connecting rod 304, and the polygonal rack 301 is slidably connected to the upper surface of the slide 102.

[0030] Specifically, the cooperation between the base 101, the slide 102 and the driving assembly 200 enables the driving assembly 200 to output power stably, thereby providing an abundant power source for clamping and straightening. The fixed connection between the pen-shaped cylinder 201 and the straight shaft 204 can directly transmit the power at the output end of the pen-shaped cylinder 201 to the straight shaft 204. The meshing of the polygonal rack 301 and the spur gear 302 can convert the linear displacement of the pen-shaped cylinder 201 into meshing circular motion, thereby meeting the requirements of clamping and straightening packaging bags of different sizes and volumes. The clamping and straightening requirements reflect the practicality of the device. The cooperation between the primary connecting rod 304 and the spur gear 302 enables the rotation amplitude of the primary connecting rod 304 to be regulated by the spur gear 302. The precise engagement of the teeth can help the circular motion of the primary connecting rod 304 to be more stable and uniform, reducing the occurrence of rotation deviation. The sliding connection between the polygonal rack 301 and the slide 102 can make the linear displacement of the polygonal rack 301 smooth and stable, thereby helping the clamping and straightening effect of the clamping member 309 to be more uniform and consistent.

[0031] Furthermore, the spur gear 302 is connected with a central shaft 303, and the central shaft 303 is fixedly connected to the top of the base 101 through a turntable bearing. The top of the central shaft 303 is rotatably connected with a primary connecting rod 304, and the outer surface of the pen-shaped cylinder 201 is fixedly sleeved with a counterweight ring 202.

[0032] Preferably, the center shaft 303 and the top of the base 101 are fixed by a turntable bearing, so that the center shaft 303 as an intermediate transmission support shaft can remain relatively stable, and can create stable conditions for multiple transmissions of the primary connecting rod 304. The counterweight ring 202 and the pen-shaped cylinder 201 are arranged so that the pen-shaped cylinder 201 can maintain its own stability.

[0033] Afterwards, a hinge shaft 305 is fixedly passed through the end surface of the primary connecting rod 304 , and a secondary connecting rod 306 is hingedly connected to the outer side of the hinge shaft 305 .

[0034] In the above, the hinge connection between the hinge shaft 305 and the secondary connecting rod 306 can transmit the rotational motion again. At the same time, the setting of the hinge shaft 305 can reduce the shaking during rotation, which is conducive to the stable straightening of the clamping member 309 and better meets the clamping requirements of the packaging bag.

[0035] When in use, first open the slide 102 on the upper surface of the base 101, then install the coupling 203 at the predetermined position on the top of the base 101, then fix the straight shaft 204 to the output end of the pen-shaped cylinder 201, and slide the polygonal rack 301 to the upper surface of the slide 102. Further, fix the polygonal rack 301 to the end face of the straight shaft 204, and then plug and fix the center shaft 303 to the center of the spur gear 302. The center shaft 303 is fixed to the top of the base 101 through a turntable bearing. Finally, the hinge shaft 305 and the secondary connecting rod 306 are installed in accordance with the transmission sequence and with the primary connecting rod 304 for stable straightening of the clamping member 309.

[0036] In summary, through the cooperation of the base 101, the slide 102 and the driving assembly 200, the driving assembly 200 can output power stably, thereby providing a sufficient power source for clamping and straightening. The fixed connection between the pen-shaped cylinder 201 and the straight shaft 204 can directly transmit the power at the output end of the pen-shaped cylinder 201 to the straight shaft 204. The meshing of the polygonal rack 301 and the spur gear 302 can convert the linear displacement of the pen-shaped cylinder 201 into a meshing circular motion, which meets the needs of packaging bags of different sizes and volumes. The need for clamping and straightening reflects the practicality of the device. The cooperation between the primary connecting rod 304 and the spur gear 302 enables the rotation amplitude of the primary connecting rod 304 to be regulated by the spur gear 302. The precise engagement of the teeth can help the circular motion of the primary connecting rod 304 to be more stable and uniform, reducing the occurrence of rotation deviation. The sliding connection between the polygonal rack 301 and the slide 102 can make the linear displacement of the polygonal rack 301 smooth and stable, thereby helping the clamping and straightening effect of the clamping member 309 to be more uniform and consistent.

[0037] Example 2

[0038] Reference Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts to achieve a uniform clamping effect of the clamping member 309.

[0039] Specifically, the upper surface of the base 101 is fixedly connected with a positioning shaft 307 , the top of the positioning shaft 307 is rotatably connected to the secondary connecting rod 306 , and the end surface of the secondary connecting rod 306 is rotatably connected to the clamping member 309 via a pin shaft.

[0040] Furthermore, the rotation connection between the positioning shaft 307 and the secondary connecting rod 306 supports the rotation of the secondary connecting rod 306, allowing the secondary connecting rod 306 to rotate stably in the plane where the top of the positioning shaft 307 is located, reducing the occurrence of up and down bumps of the secondary connecting rod 306, and the clamping member 309 connected to the secondary connecting rod 306 can clamp stably.

[0041] There are two clamping members 309 , both of which are integrally formed polyethylene arc clamps, and inner ring pieces 310 are inserted into the inner side surfaces of the clamping members 309 .

[0042] Preferably, the plug-in arrangement of the clamping member 308 and the inner ring piece 310 makes the clamping and straightening of the packaging bag smooth and uniform, significantly reduces the damage and bruises on the outer side of the packaging bag, and indirectly improves the product quality of the packaging bag.

[0043] When in use, first fix the positioning shaft 307 on the top of the base 101, then rotate the secondary connecting rod 306 to the top of the positioning shaft 307, and then rotate the clamping piece 309 and the secondary connecting rod 306 through the pin shaft. The inner ring piece 310 is inserted into the inner side of the clamping piece 309 to reduce the damage to the packaging bag.

[0044] In summary, by further connecting the positioning shaft 307 with the secondary connecting rod 306 in a rotational manner, the rotation of the secondary connecting rod 306 is supported, and the secondary connecting rod 306 can stably rotate in the plane where the top of the positioning shaft 307 is located, thereby reducing the occurrence of up and down bumps of the secondary connecting rod 306. The clamping member 309 connected to the secondary connecting rod 306 can stably clamp; the plug-in arrangement of the clamping member 308 and the inner ring piece 310 makes the clamping and straightening of the packaging bag smooth and uniform, and significantly reduces the damage and bumps on the outer side of the packaging bag, thereby indirectly improving the product quality of the packaging bag.

[0045] Example 3

[0046] Reference Figure 2-4 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts to achieve the stable supporting effect of the stabilizing rod 308.

[0047] Specifically, the clamping assembly 300 where the clamping member 309 is located further includes a stabilizing rod 308 , one end of which is rotatably connected to the positioning shaft 307 , and the other end of which is fixedly connected to the base 101 via a through rod.

[0048] Furthermore, the rotational support of the stabilizing rod 308 and the positioning shaft 307 allows the stabilizing rod 308 to provide long-term support to the secondary connecting rod 306, and the transmission movement of the secondary connecting rod 306 is more stable. At the same time, the stabilizing rod 308 can also serve as an "intermediate lever" of the secondary connecting rod 306. When the rotational torque of the secondary connecting rod 306 is insufficient, the stabilizing rod 308 can provide additional torque for the secondary connecting rod 306, helping the transmission of the secondary connecting rod 306 to be smoother and more continuous, and the clamping of the clamping member 309 can be carried out continuously.

[0049] Preferably, the length and movement trajectory of the stabilizing rod 308 are consistent with those of the primary connecting rod 304, and the rotation angle of the stabilizing rod 308 is an acute angle.

[0050] Among them, the stabilizing rod 308 is set to maintain the same trajectory as the primary connecting rod 304, so that the initial rotation of the primary connecting rod 304 is basically synchronized with the intermediate transmission of the stabilizing rod 308, which makes the transmission efficiency higher and the transmission loss reduced, which is conducive to ensuring the long-term straightening of the clamping member 309.

[0051] When in use, first fix the bottom of the stabilizing rod 308 to the base 101, and rotatably install the top of the stabilizing rod 308 to the positioning shaft 307, then adjust the rotation position of the stabilizing rod 308 and the positioning shaft 307, so that the stabilizing rod 308 and the primary connecting rod 304 keep rotating synchronously, which is used for long-term straightening of the clamping member 309.

[0052] In summary, through the rotational support of the stabilizing rod 308 and the positioning shaft 307, the stabilizing rod 308 can provide long-term support to the secondary connecting rod 306, and the transmission movement of the secondary connecting rod 306 is more stable. At the same time, the stabilizing rod 308 can also serve as the "intermediate lever" of the secondary connecting rod 306. When the rotational torque of the secondary connecting rod 306 is insufficient, the stabilizing rod 308 can provide additional torque for the secondary connecting rod 306, helping the transmission of the secondary connecting rod 306 to be smoother and more continuous, and the clamping of the clamping member 309 can be carried out continuously.
