[0025] It also includes foam 305; the foam 305 is fixedly connected to the first suction plate 5; the foam 305 is made of polyurethane material and has good air permeability and elasticity.

[0026] The following is a detailed description of the pasting process of the handle portion 3 of the handbag: First, manually place the paper bag 10 on the support plate 208 so that the bag opening of the paper bag 10 is located between the two second suction plates 210, control the first driving member 209 to drive the two second suction plates 210 to fit the upper surface and the lower surface of the bag opening respectively, and control the external vacuum device to make the second suction plates 210 suck the paper bag 10, and then control the two second suction plates 210 to move away from each other, so that the bag opening of the paper bag 10 is opened, thus completing the preparation work of the paper bag 10. At the same time, control the first electric slider 202 to move rightward on the first slide rail 201, so that the second slide rail 203 and its connecting parts move rightward synchronously, until the first suction plate 5 is aligned with the bottom of the feeder 2, as shown in FIG. Figure 3As shown, at this time, the rotating plate 9 forms an angle of 90° with the adjacent scraper 7001, the scraper 7001 is located above the first suction plate 5, the first airbag 303 and the second airbag 304 are inflated, and then the handheld portion 3 at the bottom of the collecting bin is sucked by the electric-controlled suction cup on the unloader 2 and placed on the scraper 7001, and the middle part of the handheld portion 3 is supported by the scraper 7001. When the handheld portion 3 is folded or bent, the handheld portion 3 is not pasted evenly when it is subsequently pasted to the paper bag 10, which may easily cause the handheld portion 3 to fall off and reduce the production quality of the paper bag 10. For this reason, based on the view from top to bottom, the left direct-drive motor 8 is controlled to drive the rotating plate 9 on the left to rotate counterclockwise by 90° to make it parallel to the scraper 7001 on the left. , the exhaust hole 9001 on the left side faces the left side. Similarly, the right rotating plate 9 rotates clockwise to be parallel to the scraper strip 7001 on the right side, and the exhaust hole 9001 on the right side faces the right side. Then the external air pump device is controlled to evacuate the second air bag 304 to compress the second air bag 304, so that the rotating plate 9 moves downward to fit the upper surface of the handheld part 3, and pressure is applied to the handheld part 3 through the rotating plate 9, so that the rotating plate 9 cooperates with the adjacent scraper strip 7001 to clamp the middle part of the handheld part 3, and then the two third electric sliders 302 are controlled to drive the adjacent bottom plates 6 to move away from each other on the third slide rail 301, thereby driving the corresponding rotating plate 9 and the scraper strip 7001 to smooth the handheld part 3 from the middle to the left and right sides, so that the handheld part 3 is in a straight state. In the process of smoothing the handheld part 3 In the process, the synchronous control device starts to continuously pump air from the first suction plate 5, so that suction is generated at the air inlet 5001. As the rotating plate 9 and the scraper strip 7001 move away from the middle part of the handheld portion 3, the middle part of the handheld portion 3 begins to be gradually sucked by the first suction plate 5. It is explained here that according to the thickness of the handheld portion 3, the degree of suction of the second air bag 304 by the external air pump device is adjusted, so that the force of the rotating plate 9 clamping the handheld portion 3 can be adaptively adjusted to avoid the situation where the clamping force is too large and the handheld portion 3 is torn and damaged. At the same time, the lower surface of the rotating plate 9 and the upper surface of the scraper strip 7001 are both smooth surfaces, which reduces the friction between the rotating plate 9 and the scraper strip 7001 and the handheld portion 3, thereby reducing the pulling force on the handheld portion 3 when it is flattened, and when the handheld portion During the smoothing process of the handle 3, the external air supply device is controlled to supply air to the rotating plate 9, so that the airflow is blown from the exhaust hole 9001 to the surface of the handle 3, so as to blow away impurities such as dust and paper scraps on the surface of the handle 3, thereby avoiding impurities mixed into the glue and causing the glue strength to decrease, thereby improving the pasting quality. At the same time, the first suction plate 5 is controlled to continuously suck air, so that the smoothed part of the handle 3 is firmly adsorbed by the first suction plate 5, until the rotating plate 9 and the scraper 7001 move and separate from the left and right edges of the handle 3. At this time, the handle 3 is flatly adsorbed on the first suction plate 5. At the same time, the rotating plate 9 and the scraper 7001 are located outside the edge of the first suction plate 5, and the external air pump device is controlled to suck the first air bag 303 to compress the first air bag 303.Then, the first electric slider 202 is controlled to drive the first suction plate 5 and its connecting parts and the portable part 3 to continue to move to the left. At the same time, the motor on the electrically controlled glue coating roller 4 is controlled to rotate, and the glue coating roller is rotated clockwise based on the view from front to back, so that the glue on the glue coating roller is evenly applied to the upper surface of the portable part 3. Then, the first suction plate 5 is controlled to continue to move to the left until it is aligned with the center position of the paper bag 10. Then, the second electric slider 204 is controlled to move up and down in the second slide rail 203 to adjust the height position of the portable part 3 to align with the upper surface of the support plate 208. Then, the second driving member 205 is controlled to drive the fixed frame 206, the brushless motor 207, the first suction plate 5 and the portable part 3 to move backward, so that the first suction plate 5 and the portable part 3 extend into the paper bag 10. The first suction plate 209 is controlled to drive the second suction plate 210 to move downward, so that the inner upper side surface of the bag opening of the paper bag 10 is fitted with the handheld portion 3, and pressure is applied to the handheld portion 3 by the second suction plate 210, so that the handheld portion 3 and the upper half of the bag opening of the paper bag 10 are tightly fitted, thus completing the fitting of the inner upper side surface of the paper bag 10 with the handheld portion 3, then controlling the first suction plate 5 and its connecting parts to reset, and sucking the second handheld portion 3 and completing the gluing in a manner consistent with the above process, then controlling the brushless motor 207 to drive the first suction plate 5 to rotate 180°, so that the glued surface of the handheld portion 3 faces downward, then the handheld portion 3 is sent into the bag opening of the paper bag 10, and controlling the lower first driving member 209 to drive the lower second suction plate 210 to fit the handheld portion 3, thus completing the pasting process of the paper bag 10, then manually only needs to remove the paper bag 10 from the support plate 208, and then place a new paper bag 10 on the support plate 208 for subsequent pasting processes. ,

[0027] Compared with the conventional method of pasting the handle portion 3, during the pasting process of the handle portion 3, the scraper strip 7001 and the rotating plate 9 are used to smooth the handle portion 3 to ensure that the handle portion 3 and the paper bag 10 can fit closely, thereby improving the pasting quality and eliminating the need for manual correction of the handle portion 3, thereby improving production efficiency. In addition, through automatic feeding, automatic gluing and automatic pasting, the workload of workers is greatly reduced, and uneven quality caused by errors in manual pasting is avoided, thereby ensuring the yield rate of the paper bag 10.

[0028] On this basis, since the handheld portion 3 is provided with a handle rope for easy picking, the thickness of the handle rope is greater than the thickness of the paper of the handheld portion 3. When the second suction plate 210 applies pressure to the handheld portion 3, the handle rope is located between the first suction plate 5 and the second suction plate 210, thereby preventing the second suction plate 210 from completely fitting with the first suction plate 5, so that the handheld portion 3 and the paper bag 10 cannot be completely fitted. For this reason, by arranging a foam 305 on the upper side of the first suction plate 5, since the foam 305 has good air permeability and elasticity, the handheld portion 3 is adsorbed by the foam 305 instead of the first suction plate 5. When the second suction plate 210 applies pressure to the handheld portion 3, the foam 305 can be deformed according to the contour of the handle rope on the handheld portion 3 adaptively, thereby ensuring that the second suction plate 210 and the foam 305 can be completely fitted. In this way, the fit between the handheld portion 3 and the paper bag 10 is improved, thereby improving the pasting quality.

[0029] On this basis, since the glue needs to drop to a certain temperature before solidifying, and the glue on the handle 3 is still warm after the lamination is completed, the adhesive strength of the glue is weak at this time, and when the paper bag 10 is subsequently carried, there is a relative movement between the handle 3 and the paper bag 10, which causes the handle 3 to be skewed, reducing the production quality of the paper bag 10. To avoid this situation, after the glue is applied to the handle 3, if Figure 7 As shown, the direct drive motor 8 is controlled to drive the rotating plate 9 to rotate, so that the exhaust holes 9001 of the two rotating plates 9 are facing the front side, and then the external air pump device is controlled to continue to evacuate the first air bag 303, thereby driving the fixed plate 7 and the connecting parts to continue to move downward until the exhaust hole 9001 of the rotating plate 9 is facing the foam 305, and then the handheld part 3 is fitted through the second suction plate 210, and the first suction plate 5 is controlled to stop sucking air, and the low-temperature gas is transported to the inside of the rotating plate 9 through the external air supply device, so that the low-temperature gas is blown from the exhaust hole 9001 to the front side toward the foam 305. Since the foam 305 has good air permeability, the low-temperature gas continues to flow to the front side through the pores in the foam 305. In this way, the low-temperature gas flows through the lower surface of the handheld part 3, so that the glue between the handheld part 3 and the paper bag 10 is quickly cooled, and then the glue is quickly solidified, thereby avoiding the skewness of the handheld part 3 and improving the production quality of the paper bag 10. Example 2

[0030] On the basis of Example 1, Figure 6-Figure 8 As shown, in order to prevent glue overflow from the front and rear edges of the handle portion 3 , the width of the electrically controlled glue coating roller 4 is set to be smaller than the width of the handle portion 3 .

[0031] Furthermore, in order to reduce the resistance of the scraper strip 7001 when scraping, the upper side of the scraper strip 7001 is set as a slope 7002.

[0032] It also includes a third suction plate 306; two front-to-rear symmetrical third suction plates 306 are rotatably connected to the first suction plate 5 through a torsion spring; the structure of the third suction plate 306 is the same as that of the first suction plate 5, and all the third suction plates 306 are connected to the external air extraction device; the left and right sides of each third suction plate 306 are fixedly connected to a limiting block 30601; the foam 305 covers the upper side of the third suction plate 306; the connection between the third suction plate 306 and the first suction plate 5 is a rotating shaft 30602.

[0033] When the second suction plate 210 is pasting the handbag 3, glue overflows from the edge of the handbag 3. The overflowed glue is thick and difficult to dry. When the handbag 3 is pasted, the bag mouth of the paper bag 10 will be restored to a closed state. At this time, the overflowed glue will stick to the inner side of the bag mouth of the paper bag 10, thereby affecting the normal opening of the paper bag 10. Therefore, when the handbag 3 is pasted with glue, the third suction plate 306 is in a horizontal state. The first suction plate 5 and the two third suction plates 306 together form an integral suction plate. By controlling the fixing plate 7 The scraper strip 7001 is driven to move downward, so that the scraper strip 7001 is fitted with the upper surface of the limit block 30601. Since the third suction plate 306 is rotatably connected to the first suction plate 5, as the scraper strip 7001 drives the limit block 30601 to move downward, the third suction plate 306 located at the front side rotates clockwise around the rotation axis 30602 at the front side, and the third suction plate 306 located at the rear side rotates counterclockwise around the rotation axis 30602 at the rear side. The first suction plate 5 and the second suction plate 210 are pressed against the first suction plate 5, and the second suction plate 210 is pressed against the first suction plate 5. The second suction plate 210 is ... 7001 moves upward to be flush with the upper surface of the handle portion 3, and at the same time, the limit block 30601 is separated from the squeezing of the scraper strip 7001. Under the action of the torsion spring between the scraper strip 7001 and the first suction plate 5, the third suction plate 306 is reset to a horizontal state, so that the front and rear edges of the handle portion 3 are closely attached to the paper bag 10, and by setting the width of the electronically controlled glue coating roller 4 to be smaller than the width of the handle portion 3, the front and rear edges of the handle portion 3 are in an un-glued state, thereby preventing the front and rear edges of the handle portion 3 from overflowing with glue.

[0034] On this basis, when the middle part of the handheld portion 3 is attached to the paper bag 10, the glue between the handheld portion 3 and the paper bag 10 will overflow in the front-back and left-right directions, and the glue overflowing in the front-back direction is just filled between the front and rear edges of the handheld portion 3 and the paper bag 10, so as to prevent the front and rear edges of the handheld portion 3 from warping. At the same time, there is also glue overflow on the left and right edges of the handheld portion 3, and at this time, the scraper strip 7001 is just attached to the left and right edges of the handheld portion 3, so that the scraper strip 7001 The upper surface of 001 contacts the overflowed glue, and the left scraper 7001 is taken as an example for detailed description. At this time, the left scraper 7001 is attached to the left edge of the joint of the handheld portion 3 and the paper bag 10, and the overflowed glue is located between the paper bag 10 and the scraper 7001. The third electric slider 302 on the left is controlled to drive the scraper 7001 to scrape to the left along the paper bag 10, so that the overflowed glue is scraped flat by the scraper 7001. Compared with the overflowed glue gathered at the edge of the handheld portion 3, when the glue After being scraped flat, its surface area contact with the air increases, which is conducive to the rapid drying of the overflowed glue. At the same time, the low-temperature gas blown out through the exhaust hole 9001 quickly cools down the overflowed glue to ensure that the overflowed glue is completely dried, so that the overflowed glue is dried before the bag mouth of the paper bag 10 is closed, thereby avoiding affecting the normal use of the subsequent paper bag 10. On this basis, by setting the upper side of the scraper strip 7001 as an inclined surface 7002, the contact area between the scraper strip 7001 and the paper bag 10 is reduced, thereby reducing the resistance of the scraper strip 7001 when scraping. In this way, compared with the conventional method of pasting the handle 3, the scraper strip 7001 is used to scrape the overflowed glue on the left and right edges of the handle 3 to accelerate the drying of the glue, and by reducing the amount of glue applied on the front and rear edges of the handle 3, overflowed glue is avoided on the front and rear edges of the handle 3, thereby avoiding the overflowed glue sticking to the inner side of the bag mouth of the paper bag 10, thereby affecting the normal opening of the paper bag 10.
