Description

Technical Field

[0001] The present invention relates to the technical field of bag-making equipment, and particularly to a two-piece non-woven fabric flour bag-making equipment and method. Background Art

[0002] In recent years, non-woven fabric bags have been increasingly recognized by the market, and non-woven fabric flour bags have also been more and more widely used. At present, non-woven fabric flour bags are all made by non-woven fabric bag-making machines. The non-woven fabric bag-making machine includes a bag body forming mechanism and a bag body demolding device. After the bag is formed by the bag body forming mechanism, the bag is then detached from the forming mold by the bag body demolding device; after the bag is detached, it enters the bag body folding device installed below the bag body demolding device, and then the bag is folded into a flat shape by the bag body folding device, and finally conveyed outside and packed into boxes. A variety of non-woven fabric bag-making machines have been proposed in the prior art. For example, a new type of non-woven fabric bag-making and folding integrated machine proposed in the Chinese invention application with the application number CN201911378700.3; and also, a new type of non-woven fabric bag-making and folding integrated machine proposed in the Chinese invention application with the application number CN201811208939.1.

[0003] However, the bag-making machines proposed in the above prior art do not have the function of inspecting the thickness of non-woven fabrics and cannot identify defects in non-woven fabrics. Since non-woven fabric flour bags need to load 5KG, 10KG or even 20KG of flour and bear a large weight, when stacking or transporting flour bags, when there are thinner parts in the non-woven fabric, it is easy to cause the flour to squeeze and break the flour bag at the thinner part and leak, resulting in economic losses. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a two-piece non-woven fabric flour bag-making equipment and method that can inspect the thickness of non-woven fabrics, repair thinner parts, improve the reliability of non-woven fabric flour bags, reduce the risk of flour leakage, and reduce economic losses.

[0005] A two-piece non-woven fabric flour bag making device and method of the present invention include a cloth roll roller, a first roller group and a second roller group. The cloth roll roller loads a non-woven fabric roll, and the first roller group and the second roller group spread the non-woven fabric and convey it backward; it also includes a support plate, a first lamp row, a mounting frame, a light detector, a repair mechanism and a bag making mechanism. The support plate is installed on the frame of the first roller group, the support plate is located below the non-woven fabric, and the first lamp row is installed on the support plate.

The plurality of receiving units of the light detector provide repair position information for the repair mechanism. The repair mechanism repairs the unqualified parts of the non-woven fabric thickness. The second roller group flattens the repaired non-woven fabric. The bag making mechanism is located behind the second roller group. The bag making mechanism makes the non-woven fabric into a flour bag; the positions of the plurality of receiving units of the light detector are encoded. During work, the cloth roll roller loads the non-woven fabric roll, and the non-woven fabric is conveyed backward through the first roller group and the second roller group. The first roller group and the second roller group spread the non-woven fabric. When the non-woven fabric is conveyed, the first lamp row on the support plate irradiates the bottom of the non-woven fabric, and the optical fiber irradiates the light detector through the non-woven fabric. The plurality of receiving units on the light detector detect the intensity of the received light. When a certain receiving unit detects that the light intensity is less than the set value, it is judged that the non-woven fabric thickness below it is unqualified. The unqualified position is located according to the encoding of the receiving unit and the conveying speed of the non-woven fabric, and the positioning information is sent to the repair mechanism, and the actual thickness of the non-woven fabric and the difference from the qualified data are judged by detecting the specific intensity of the light. The repair amount is provided for the repair mechanism through the difference. The repair mechanism repairs the non-woven fabric according to the positioning information and the repair amount. The second roller group flattens the repaired part when conveying the non-woven fabric. The second roller group conveys the non-woven fabric to the bag making mechanism.

The non-woven fabric fiber raw materials in the raw material box are input into the extruder to be melted. The extruder inputs the melted raw materials into the repair nozzle through the hose. The rotation of the synchronous pulleys drives the rotation of the synchronous belt, and the synchronous belt drives the repair nozzle to move to the position where the non-woven fabric is unqualified. The repair nozzle sprays an appropriate amount of non-woven fabric fibers according to the repair amount, and the non-woven fabric fibers repair the unqualified part, realizing automatic repair.

[0007] Preferably, it is also connected to a recycling mechanism. The recycling mechanism is used to recycle the cut non-woven fabric waste edges, and the raw material box is connected to the recycling mechanism. The recycling mechanism sends the collected non-woven fabric waste materials into the raw material box, so as to directly recycle the non-woven fabric waste materials and improve the practicability.

The receiving unit of the light detector is arranged at the lower part of the repair nozzle. The second lamp row irradiates the non-woven fabric. When the synchronous pulleys drive the synchronous belt to rotate and the repair nozzle reaches the unqualified position provided by the light detector, the receiving unit at the lower part of the repair nozzle receives the light emitted by the second lamp row and identifies the unqualified position, so as to accurately locate the unqualified position and improve the accuracy of the repair by the repair nozzle.

[0009] Preferably, it also includes two wheel frames, two shock-absorbing springs, an upper indentation wheel, and a lower indentation wheel. The middle parts of the two wheel frames are rotatably installed on the frame of the second roller group. One ends of the two shock-absorbing springs are rotatably connected to the frame of the second roller group, and the other ends of the two shock-absorbing springs are respectively rotatably connected to one ends of the two wheel frames.

The upper indentation wheel and the lower indentation wheel are respectively located above and below the non-woven fabric, and the upper indentation wheel and the lower indentation wheel are aligned with the midline of the non-woven fabric up and down. The elastic forces of the two shock-absorbing springs press the upper indentation wheel and the lower indentation wheel tightly against the upper surface and the lower surface of the non-woven fabric through the two wheel frames, so that the upper indentation wheel and the lower indentation wheel roll out a folding mark at the midline of the non-woven fabric, which is convenient for the accurate folding of the non-woven fabric when making bags and improves the bag-making accuracy.

[0010] Preferably, the bag-making mechanism includes two columns, two sliding plates, two bag-making molds, a hinge, four sealing strips, and two lifting cylinders. The two columns are installed at the rear side of the second roller group, and the two columns are arranged symmetrically left and right.

The fixed ends of the two lifting cylinders are located on both sides of the middle of the two columns. The piston rods of the two lifting cylinders are connected to the pin shaft of the hinge through a rotating shaft. Before bag-making, the two bag-making molds are horizontally unfolded at the tops of the two columns. The second roller group inputs the non-woven fabric onto the upper end surfaces of the two bag-making molds and cuts the non-woven fabric. The piston rods of the two lifting cylinders contract, pulling the pin shaft of the hinge downward to the middle of the two columns, thereby driving the two bag-making molds to slide along the two sliding plates. At the same time, the two sliding plates rotate on the two columns, causing the two bag-making molds to rotate to the vertical buckling state, and the two sides of the non-woven fabric are buckled together by the two bag-making molds. The sealing strips are ultrasonic sealing strips or heating sealing strips. The four sealing strips are aligned, and the four sealing strips seal the two sides of the non-woven fabric, thereby sealing the bottom and two sides of the non-woven fabric to form a flour bag. After bag-making is completed, the piston rods of the two lifting cylinders extend to reset the two bag-making molds to the horizontal unfolded state, and the flour bag is taken off, realizing rapid bag-making with high working efficiency.

The loading beam spans across the two bag-making molds. A plurality of second suction cups are arranged on the lower end surface of the loading beam. The cutting strip is installed on the rear side wall of the loading beam. The translation assembly drives the two sliding tables to move synchronously, and the sliding tables drive the loading beam to move. When making bags, the loading beam adsorbs the end of the non-woven fabric conveyed by the second roller group through the second suction cups. The two sliding tables drive the loading beam to move to the rear ends of the two bag-making molds, so that the loading beam adsorbs the end of the non-woven fabric to reach the two sealing strips at the rear side. The second suction cups on the loading beam release the non-woven fabric. A plurality of first suction cups on the two bag-making molds adsorb both sides of the non-woven fabric.

When the two bag-making molds are buckled to make bags, the piston rod of the second lifting cylinder extends to make the mechanical claw extend into the grooves of the two bag-making molds, and the mechanical claw clamps the middle part of the upper end of the non-woven fabric flour bag. When the two bag-making molds are horizontally unfolded, the translation assembly drives the two sliding tables to move backward, and the two sliding tables drive the loading beam and the second lifting cylinder to move backward, so that the mechanical claw moves the non-woven fabric flour bag out of the two bag-making molds, and the mechanical claw releases it to realize automatic unloading.

The mechanical claw 33 releases to realize automatic unloading. At the same time, the loading beam 30 places the non-woven fabric on the two bag making molds 20 to complete feeding again.

[0026] As Figures 1 to 9As shown, a two-piece non-woven fabric flour bag making device and method of the present invention, when working, first, a non-woven fabric roll is loaded on the fabric roll roller 1, and the non-woven fabric is conveyed backward through the first roller group 2 and the second roller group 3. The first roller group 2 and the second roller group 3 stretch the non-woven fabric. The light row 5 on the support plate 4 irradiates the bottom of the non-woven fabric, and the optical fiber irradiates the light measuring device 7 through the non-woven fabric. Multiple receiving units on the light measuring device 7 detect the intensity of the received light. When a certain receiving unit detects that the light intensity is less than the set value, it is determined that the thickness of the non-woven fabric below it is unqualified. The unqualified position is located according to the coding of the receiving unit and the conveying speed of the non-woven fabric, and the positioning information is sent to the repair mechanism, and the difference between the actual thickness of the non-woven fabric and the qualified data is judged by detecting the specific intensity of the light, and the repair amount is provided for the repair mechanism through the difference. Then, the non-woven fabric fiber raw material in the raw material box 11 is input into the extruder 12 to be melted, and the extruder 12 inputs the melted raw material into the repair spray head 10 through a hose. The synchronous pulley 8 rotates to drive the synchronous belt 9 to rotate. The light row 13 irradiates the non-woven fabric. When the synchronous pulley 8 drives the synchronous belt 9 to rotate so that the repair spray head 10 reaches the unqualified position provided by the light measuring device 7, the receiving unit under the repair spray head 10 receives the light emitted by the light row 13 and identifies the unqualified position, so as to accurately position the unqualified position. The repair spray head 10 sprays an appropriate amount of non-woven fabric fiber according to the repair amount, and the non-woven fabric fiber repairs the unqualified place. The second roller group 3 flattens the repaired place when conveying the non-woven fabric. Then, the translation assembly 28 drives the two sliding tables 29 to move synchronously, and the sliding tables 29 drive the feeding beam 30 to move. When making a bag, the feeding beam 30 adsorbs the end of the non-woven fabric conveyed by the second roller group 3 through the second sucker. The two sliding tables 29 drive the feeding beam 30 to move to the rear end of the two bag-making molds 20, so that the feeding beam 30 adsorbs the end of the non-woven fabric and reaches the two sealing strips 22 at the rear side. The second sucker of the feeding beam 30 releases the non-woven fabric. Multiple first suckers 26 on the two bag-making molds 20 adsorb both sides of the non-woven fabric. The two sliding tables 29 drive the feeding beam 30 to move to the front end of the two bag-making molds 20, so that the cutting strip 31 reaches the two sealing strips 22 at the front side. The second sucker of the feeding beam 30 adsorbs the non-woven fabric again, and the cutting strip 31 cuts off the non-woven fabric on the two bag-making molds 20. The piston rods of the two lifting cylinders 23 contract, pulling the pin shaft of the hinge 21 downward to the middle of the two columns 18, thereby driving the two bag-making molds 20 to slide along the two sliding plates 19. At the same time, the two sliding plates 19 rotate on the two columns 18, so that the two bag-making molds 20 rotate to the vertical buckling state, and both sides of the non-woven fabric are buckled together by the two bag-making molds 20, and the four sealing strips 22 are aligned. The four sealing strips 22 seal both sides of the non-woven fabric, so that the bottom and both sides of the non-woven fabric are sealed to form a flour bag. Finally, the piston rod of the second lifting cylinder 32 extends so that the mechanical claw 33 extends into the groove of the two bag-making molds 20, and the mechanical claw 33 clamps the middle part of the upper end of the non-woven fabric flour bag. The piston rods of the two lifting cylinders 23 extend so that the two bag-making molds 20 are reset to the horizontal expansion state.The translation component 28 drives the two sliders 29 to move backward. The two sliders 29 drive the feeding beam 30 and the second lifting cylinder 32 to move backward, so that the mechanical claw 33 moves the non-woven fabric flour bag out of the two bag-making molds 20. The mechanical claw 33 releases to achieve automatic blanking. At the same time, the feeding beam 30 places the non-woven fabric on the two bag-making molds 20 to make bags again.

It can detect the thickness of the non-woven fabric, repair the thinner parts, improve the reliability of the non-woven fabric flour bag, reduce the risk of flour leakage, and reduce economic losses; 2.
