In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0032] See also Figure 1-5 As shown, the utility model provides a technical solution of a packaging bag packaging mechanism: a packaging bag packaging mechanism, comprising a bottom frame 1, a packaging mechanism 2 for automatic packaging is arranged inside the bottom frame 1, and a belt threading mechanism 3 for belt threading is arranged on the upper end surface of the bottom frame 1;

[0033] The packaging mechanism 2 includes a driving motor 201, a double-rod cylinder 203, a load-bearing cylinder 205, and a guide rod cylinder 209. The driving motor 201 is fixedly installed inside the bottom frame 1, and the output end of the driving motor 201 is connected to the packaging tape reel 202. The double-rod cylinder 203 is fixedly installed on the inner side of the bottom frame 1, and the output end of the double-rod cylinder 203 is fixedly connected to the top plate 204. The upper end surface of the bottom frame 1 is slidably connected to the top plate 204 by providing a slide groove, and the lower end surface of the top plate 204 is provided with a fixing portion 2041 that fixes the end of the packaging tape. The cylinder 205 is fixedly mounted on the lower end surface of the bottom frame 1, and the output end of the load-carrying cylinder 205 is fixedly connected to the bearing plate 206. The upper end surface of the bearing plate 206 is respectively provided with a heating plate 207 for hot-melting the strapping tape and a positioning column 208 matching the shape of the fixing portion 2041. The guide rod cylinder 209 is fixedly mounted on the lower end surface of the bottom frame 1, and the output end of the guide rod cylinder 209 is connected to a tape-breaking knife 210. The side of the positioning column 208 is slidably connected to the tape-breaking knife 210 by providing a slide groove, and the inner side of the positioning column 208 is provided with a slot for convenient breaking. The through hole 211 through which the strapping tape passes, it should be noted that the height of the heating plate 207 should be less than the height of the positioning column 208, to ensure that when the positioning column 208 is positioned, the other end of the strapping tape still has a certain amount of activity space. When packaging the packaging bags, firstly, the packaging bags that have been sorted in batches need to be placed on the upper end of the top plate 204, and then the driving motor 201 is started to feed the strapping tape. After the strapping tape passes through the through hole 211 and the strapping mechanism 3, they overlap, and then the load cylinder 205 is started until the positioning column 208 and the top plate 204 fix the end of the strapping tape. At this time, the driving motor 201 is started to feed the strapping tape. The motor 201 rotates in the reverse direction, so that the strapping tape retracts, tightens and is tightly bound to the surface of the packaging bag. Then, the heating plate 207 is powered by an external power supply device to heat it and hot-melt-bond the folded portion of the strapping tape. Then, the guide rod cylinder 209 pushes the tape-breaking knife 210 to move upward to cut the end of the strapping tape. After the cutting is completed, the double-rod cylinder 203 retracts and drives the top plate 204 to move. After the strapping tape is separated from the top plate 204, the packaged packaging bag can be taken out. The whole process is fast, which significantly improves the packaging speed and reduces the time required for manual operation.

[0034] The strapping mechanism 3 includes an annular outer frame 301 and a blocking plate 303. The annular outer frame 301 is fixedly mounted on the upper end surface of the bottom frame 1. An annular groove 302 is provided on the inner side of the annular outer frame 301 for facilitating the strapping tape to be threaded. The blocking plate 303 is fixedly mounted on the side wall of the annular outer frame 301 by a spring hinge and is located on the outer side of the annular groove 302. During the strapping tape threading process, the driving motor 201 transmits the strapping tape, and the strapping tape passes through the perforation 211 and continues to move upward to the inside of the annular groove 302 and overlaps after wrapping around it for a circle to achieve pre-embedding. In the process of tightening the strapping tape, one end of the strapping tape is fixed by the positioning column 208 and the other end is flipped and pulled by the driving motor 201. Therefore, the retraction of the strapping tape will break through the restriction of the blocking plate 303, causing the blocking plate 303 to open and finally wrap around the packaging bag. While assisting the pre-embedding work, it provides convenience for the winding of the strapping tape, improves work efficiency, and ensures the continuity of the operation process.

[0035] The blocking plate 303 is provided with a slide-out portion 3031. By designing the slide-out portion 3031, the annular groove 302 can be moved out more smoothly during the tightening process of the strapping belt, thereby reducing the friction and resistance encountered by the strapping belt, thereby improving the efficiency of the entire packaging process.

[0036] The corners of the annular outer frame 301 are all arc-shaped. By designing the corners of the annular outer frame 301 to be arc-shaped, the strapping tape can be guided through the corner part more smoothly, avoiding the problem of the strapping tape being stuck or squeezed at the corner.

[0037] The blocking plate 303 and the belt-breaking knife 210 are both made of stainless steel. By designing the blocking plate 303 and the belt-breaking knife 210 to be made of stainless steel, the service life of the mechanism can be increased and the maintenance cost can be reduced.

[0038] The interior of the bottom frame 1 is provided with positioning rollers 4 through a support frame. By providing the positioning rollers 4, the strapping tape can be effectively guided to be transmitted along a predetermined path, ensuring that the strapping tape is accurately positioned during the entire strapping process and the strapping process.

[0039] The working principle of the utility model is as follows:

[0040] When a packaging bag packaging mechanism of the present embodiment is packaging the packaging bags, it is first necessary to place the batch of sorted packaging bags on the upper end of the top plate 204, and then drive the motor 201 to transmit the packaging tape, the packaging tape passes through the perforation 211 and continues to move upward to the inside of the annular groove 302 and overlaps and is pre-buried after circling around it for a circle, and then start the load-bearing cylinder 205 until the positioning column 208 and the top plate 204 fix the end of the packaging tape. At this time, the driving motor 201 runs in the reverse direction, so that the packaging tape retracts, tightens and is tightly bound to the surface of the packaging bag, and then the heating plate 207 is powered by an external power supply device to heat it and hot-melt the folded part of the packaging tape, and then the guide rod cylinder 209 pushes the tape breaking knife 210 to move upward to cut the end of the packaging tape. After the cutting is completed, the double-rod air cylinder 205 is turned on. The retraction of cylinder 203 drives top plate 204 to move, and the packed packaging bag can be taken out after the strapping tape is detached from top plate 204. The packaging bag packaging mechanism significantly improves the packaging efficiency and continuity by integrating the automated packaging mechanism 2 and the strapping mechanism 3. The packaging mechanism 2 includes key components such as a driving motor 201, a strapping tape reel 202, a double-rod cylinder 203, and a top plate 204, which realize automatic strapping, bundling, hot-melt bonding, and cutting processes, speeding up the batch processing of packaging bags while reducing manual dependence and the risk of errors. The strapping mechanism 3 ensures that the strapping tape moves smoothly and is embedded in the strapping tape during the strapping tape threading process through the design of an annular outer frame 301, an annular groove 302, and a movable blocking plate 303, thereby reducing tape jams and position errors, improving strapping efficiency, and further enhancing the continuity and automation level of the packaging operation.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
