Description

Technical Field

[0001] The present invention relates to the technical field of paper bag processing, and particularly to a glue - applying and pasting machine for hand - held paper bags with rapid curing. Background Art

[0002] In the production process of existing hand - held bags, the hand - held part and the paper bag are usually produced separately first, and finally the hand - held part is pasted on the paper bag by pasting. The conventional pasting method is usually to coat one side of the hand - held part with glue using a glue - applying machine, and then manually open the paper bag and paste the glue - coated side of the hand - held part to the inner side of the bag mouth of the paper bag. When mass - producing hand - held bags, since the quality of manual pasting is related to the proficiency of workers, the quality of hand - held bags pasted by different workers is also different, resulting in uneven product quality of hand - held bags, reducing the yield rate of products. Moreover, when there are folds or bends in the paper of the hand - held part, corrective operations such as flattening and pressing need to be carried out on the hand - held part. However, it is time - consuming and laborious to correct the hand - held part manually, thus leading to a decline in production efficiency. Summary of the Invention

[0038] The following is a detailed description of the pasting process of the handle portion 3 of the handbag:

[0039] First, manually place the paper bag 10 on the support plate 208, with the bag mouth of the paper bag 10 located between the two second suction plates 210. Control the first driving member 209 to drive the two second suction plates 210 to fit onto the upper and lower surfaces of the bag mouth respectively, and control the external air extraction device to make the second suction plates 210 suck the paper bag 10. Then, control the two second suction plates 210 to move away from each other, so as to open the bag mouth of the paper bag 10. Thus, the preparatory work of the paper bag 10 is completed. At the same time, control the first electric slider 202 to move to the right on the first slide rail 201, so that the second slide rail 203 and its connecting parts move to the right synchronously until the first suction plate 5 is aligned with the lower part of the blanking machine 2, as Figure 3As shown, at this time, the turning plate 9 forms a 90° angle with the adjacent scraping strip 7001. The scraping strip 7001 is located above the first suction plate 5. The first airbag 303 and the second airbag 304 are in an inflated state. Then, the electric suction cup on the blanking machine 2 sucks the handle part 3 at the bottom of the aggregate bin and places it on the scraping strip 7001. The scraping strip 7001 supports the middle part of the handle part 3. When there are folds or bends in the handle part 3, when the handle part 3 is pasted to the paper bag 10 later, the handle part 3 may not be pasted smoothly, which may easily cause the handle part 3 to fall off and reduce the production quality of the paper bag 10. Therefore, with the top-down view as the reference, control the left direct drive motor 8 to drive the left turning plate 9 to rotate counterclockwise by 90°, making it parallel to the left scraping strip 7001. The left exhaust hole 9001 faces the left. Similarly, the right turning plate 9 rotates clockwise to be parallel to the right scraping strip 7001, and the right exhaust hole 9001 faces the right. Then, control the external air pump device to extract air from the second airbag 304, compressing the second airbag 304, so that the turning plate 9 moves downward to fit the upper surface of the handle part 3, and the turning plate 9 applies pressure to the handle part 3. In this way, the turning plate 9 cooperates with the adjacent scraping strip 7001 to clamp the middle part of the handle part 3. Then, control the two third electric sliders 302 to drive the adjacent bottom plate 6 to move away from each other on the third slide rail 301, thereby driving the corresponding turning plate 9 and scraping strip 7001 to smooth the handle part 3 from the middle to the left and right sides, making the handle part 3 in a straight state. During the process of smoothing the handle part 3, synchronously control the air extraction device to start continuously extracting air from the first suction plate 5, generating suction at the air inlet hole 5001. As the turning plate 9 and the scraping strip 7001 move away from the middle part of the handle part 3, the middle part of the handle part 3 begins to be gradually sucked by the first suction plate 5. It should be noted here that according to the different thicknesses of the handle part 3, by adjusting the degree of suction of the external air pump device on the second airbag 304, the clamping force of the turning plate 9 on the handle part 3 can be adaptively adjusted, avoiding the situation where the clamping force is too large and causing the handle part 3 to be torn and damaged. At the same time, the lower surface of the turning plate 9 and the upper surface of the scraping strip 7001 are both smooth surfaces, so as to reduce the friction between the turning plate 9 and the scraping strip 7001 and the handle part 3, thereby reducing the pulling force on the handle part 3 when it is smoothed. Moreover, during the process of smoothing the handle part 3, control the external air supply device to supply air to the turning plate 9, so that the air flow blows from the exhaust hole 9001 to the surface of the handle part 3, thereby blowing away impurities such as dust and paper scraps on the surface of the handle part 3, avoiding the mixing of impurities in the glue and resulting in a decrease in the glue strength, and thus improving the pasting quality. At the same time, control the first suction plate 5 to continuously suck air, so that the flattened part of the handle part 3 is firmly adsorbed by the first suction plate 5 until the turning plate 9 and the scraping strip 7001 move away from the left and right edges of the handle part 3. At this time, the handle part 3 is flatly adsorbed on the first suction plate 5, and at the same time, the turning plate 9 and the scraping strip 7001 are located outside the edge of the first suction plate 5. Control the external air pump device to extract air from the first airbag 303, compressing the first airbag 303.Thereby driving the fixed plate 7, the direct drive motor 8, the rotating plate 9 and the second airbag 304 to move downward until the upper surface of the rotating plate 9 is lower than the upper surface of the carrying handle 3, so as to prevent the surface of the rotating plate 9 from sticking to the glue during glue application. Then, control the first electric slider 202 to drive the first suction plate 5, its connecting parts and the carrying handle 3 to continue moving to the left. At the same time, control the motor on the electric control glue roller 4 to rotate, with the front-to-back view as the reference, so that the glue roller rotates clockwise, thereby evenly applying the glue on the glue roller to the upper surface of the carrying handle 3. Then, control the first suction plate 5 to continue moving to the left until it aligns with the center position of the paper bag 10. Then, control the second electric slider 204 to move up and down within the second slide rail 203 to adjust the height position of the carrying handle 3 to align with the upper surface of the support plate 208. Then, control the second driving member 205 to drive the fixed frame 206, the brushless motor 207, the first suction plate 5 and the carrying handle 3 to move backward, so that the first suction plate 5 and the carrying handle 3 extend into the bag mouth of the paper bag 10. Then, control the upper first driving member 209 to drive the upper second suction plate 210 to move downward, so that the inner upper side of the bag mouth of the paper bag 10 fits with the carrying handle 3, and apply pressure to the carrying handle 3 through the second suction plate 210 to make the carrying handle 3 fit tightly with the upper half side of the bag mouth of the paper bag 10. In this way, the fitting of the inner upper side of the paper bag 10 and the carrying handle 3 is completed. Subsequently, control the first suction plate 5 and its connecting parts to reset, and suck the second carrying handle 3 and complete glue application in the same way as the above process. Then, control the brushless motor 207 to drive the first suction plate 5 to rotate 180°, so that the glue-applied surface of the carrying handle 3 faces downward. Then, send the carrying handle 3 into the bag mouth of the paper bag 10, and control the lower first driving member 209 to drive the lower second suction plate 210 to fit with the carrying handle 3. In this way, the pasting process of the paper bag 10 is completed. Subsequently, the worker 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.

[0040] Compared with the conventional method of pasting the carrying handle 3, during the process of pasting the carrying handle 3, the carrying handle 3 is smoothed by the scraping strip 7001 and the rotating plate 9, ensuring that the carrying handle 3 and the paper bag 10 can fit tightly, improving the pasting quality. At the same time, the operation of manually correcting the carrying handle 3 is eliminated, improving the production efficiency. Moreover, through automatic feeding, automatic glue application and automatic fitting, the workload of workers is greatly reduced, avoiding uneven quality caused by errors in manual pasting, and ensuring the qualified rate of the paper bag 10.

[0041] On this basis, since a handle rope for easy taking is provided on the hand-held part 3, and the thickness of the handle rope is greater than the thickness of the paper of the hand-held part 3. When the second suction plate 210 presses on the hand-held part 3, the handle rope is located between the first suction plate 5 and the second suction plate 210, thus preventing the second suction plate 210 from completely fitting with the first suction plate 5, and thus the hand-held part 3 and the paper bag 10 cannot be completely fitted. Therefore, 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 foam 305 is used to adsorb the hand-held part 3 instead of the first suction plate 5. When the second suction plate 210 presses on the hand-held part 3, the foam 305 can deform adaptively according to the contour of the handle rope on the hand-held part 3, so as to ensure that the second suction plate 210 and the foam 305 can be completely fitted. In this way, the fitting degree between the hand-held part 3 and the paper bag 10 is improved, and thus the pasting quality is improved.

[0042] On this basis, since the glue needs to drop to a certain temperature before it can solidify, and after the hand-held part 3 is fitted, the glue still has residual temperature. At this time, the adhesion strength of the glue is weak, and during the subsequent handling of the paper bag 10, there is a relative movement between the hand-held part 3 and the paper bag 10, thus causing the hand-held part 3 to be skewed and reducing the production quality of the paper bag 10. To avoid such a situation, after the hand-held part 3 is coated with glue, as Figure 7 shown, control the direct drive motor 8 to drive the rotating plate 9 to rotate, so that the exhaust holes 9001 of the two rotating plates 9 both face the front side, and then control the external air pump device to continue to pump air out of the first airbag 303, thereby driving the fixing plate 7 and the connecting parts to continue to move downward until the exhaust holes 9001 of the rotating plate 9 face the foam 305, and then press the hand-held part 3 through the second suction plate 210. At this time, control the first suction plate 5 to stop sucking air, and convey low-temperature gas into the rotating plate 9 through the external air supply device, so that the low-temperature gas blows from the exhaust holes 9001 to the front side towards the foam 305. Since the foam 305 has good air permeability, the low-temperature gas continues to flow forward through the pores in the foam 305. In this way, the low-temperature gas flows through the lower surface of the hand-held part 3, so that the glue between the hand-held part 3 and the paper bag 10 is quickly cooled, and thus the rapid solidification of the glue is realized, thereby avoiding the situation that the hand-held part 3 is skewed and improving the production quality of the paper bag 10. Embodiment 2

[0043] On the basis of Embodiment 1, as Figures 6 - 8 shown, to avoid glue overflow at the front edge and the rear edge of the hand-held part 3, the width of the electric control glue applicator roller 4 is set to be less than the width of the hand-held part 3.

[0044] Furthermore, to reduce the resistance when the scraping strip 7001 scrapes, the upper side of the scraping strip 7001 is set as an inclined surface 7002.

[0045] It further includes a third suction plate 306; two symmetric third suction plates 306 are rotatably connected to the first suction plate 5 through torsion springs; 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 communicated with an external air extraction device; limiting blocks 30601 are fixedly connected to the left and right sides of each third suction plate 306; the foam 305 covers the upper side of the third suction plate 306; the connection part between the third suction plate 306 and the first suction plate 5 is a rotating shaft 30602.

[0046] When the second suction plate 210 fits the handle part 3, glue overflows at the edge position of the handle part 3, and the thickness of the overflowed glue is relatively thick and not easy to dry. When the handle part 3 is pasted, the bag mouth of the paper bag 10 will return to the closed state. At this time, the overflowed glue will stick the inner side of the bag mouth of the paper bag 10, thus affecting the normal opening of the paper bag 10. Therefore, after the glue is applied to the handle part 3, at this time, the third suction plate 306 is in a horizontal state, and the first suction plate 5 and the two third suction plates 306 together form an integral suction plate. By controlling the fixed plate 7 to drive the scraping strip 7001 to move downward, the scraping strip 7001 is made to fit the upper surface of the limiting block 30601. Since the third suction plate 306 is rotatably connected to the first suction plate 5, as the scraping strip 7001 drives the limiting block 30601 to move downward, taking the view from left to right as a reference, the front third suction plate 306 rotates clockwise around the front rotating shaft 30602, and the rear third suction plate 306 rotates counterclockwise around the rear rotating shaft 30602. The torsion spring between the third suction plate 306 and the first suction plate 5 is compressed, so that the integral suction plate changes from a flat shape to a trapezoidal shape. At the same time, the foam 305 deforms adaptively and drives the front edge and the rear edge of the handle part 3 to bend downward synchronously, thus completing the preparation work for fitting. Then, control the second driving member 205 to drive the first suction plate 5 and its connecting parts and the handle part 3 to extend into the bag mouth of the paper bag 10, and fit the handle part 3 through the second suction plate 210. During the fitting process, the middle part of the handle part 3 first fits the paper bag 10, and then control the external air pump device to inflate the first airbag 303, so that the scraping strip 7001 moves upward to be flush with the upper surface of the handle part 3, and at the same time, the limiting block 30601 is disengaged from the extrusion of the scraping strip 7001. Under the action of the torsion spring between the scraping strip 7001 and the first suction plate 5, the third suction plate 306 returns to the horizontal state, so that the front edge and the rear edge of the handle part 3 fit tightly with the paper bag 10. By setting the width of the electric control glue application roller 4 to be smaller than the width of the handle part 3, the front edge and the rear edge of the handle part 3 are in a non-glued state, so as to avoid glue overflow at the front edge and the rear edge of the handle part 3.

[0047] On this basis, when the middle part of the handle part 3 is attached to the paper bag 10, the glue between the handle part 3 and the paper bag 10 will overflow in the front-back and left-right directions. The glue overflowing in the front-back direction just fills the space between the front and rear edges of the handle part 3 and the paper bag 10, preventing the front and rear edges of the handle part 3 from warping. At the same time, there is also glue overflow at the left and right edges of the handle part 3. At this time, the scraping strip 7001 just adheres to the left and right edges of the handle part 3, so that the upper surface of the scraping strip 7001 contacts the overflowing glue. Taking the left scraping strip 7001 as an example for detailed description, at this time, the left scraping strip 7001 adheres to the left edge of the joint between the handle part 3 and the paper bag 10, and the overflowing glue is located between the paper bag 10 and the scraping strip 7001. Control the third electric slider 302 on the left to drive the scraping strip 7001 to scrape left along the paper bag 10, so as to scrape the overflowing glue flat by the scraping strip 7001. Compared with the situation where the overflowing glue accumulates at the edge of the handle part 3, when the glue is scraped flat, its surface area in contact with the air increases, which is conducive to the rapid drying of the overflowing glue. At the same time, the low-temperature gas blown out through the exhaust hole 9001 quickly cools the overflowing glue to ensure that the overflowing glue is completely dried, so as to dry the overflowing glue before the bag mouth of the paper bag 10 is closed, avoiding affecting the normal use of the subsequent paper bag 10. On this basis, by setting the upper side of the scraping strip 7001 as the inclined surface 7002, the contact area between the scraping strip 7001 and the paper bag 10 is reduced, thereby reducing the resistance when the scraping strip 7001 scrapes. In this way, compared with the conventional method of pasting the handle part 3, the overflowing glue at the left and right edges of the handle part 3 is scraped flat by the scraping strip 7001, accelerating the drying of the glue, and by reducing the amount of glue applied to the front and rear edges of the handle part 3, preventing the overflow of glue at the front and rear edges of the handle part 3, thus avoiding the situation where the overflowing glue sticks to the inner side of the bag mouth of the paper bag 10 and then affects the normal opening of the paper bag 10.
