[0002] As people's awareness of environmental protection increases, non-woven bags have the advantages of high firmness, repeated use and environmental protection, and have gradually replaced plastic film bags. In the prior art, when non-woven bags are formed, a whole roll of non-woven fabric is placed on a material rack, and the non-woven fabric is pulled by a traction mechanism, and after forming, it becomes a non-woven bag with a handle. In order to make non-woven bags reflect higher use value, merchants often print some logos or advertisements on non-woven bags, and these advertisements need to be printed on a whole roll of non-woven fabric, and the formed bag body is cut by color tracking. Therefore, printing these logos or advertisements requires a printing machine, which adds a lot of cost to the manufacturers of non-woven bags. Therefore, in order to reduce costs, manufacturers of non-woven fabrics generally use low-cost offset printing machines to print the bag body of non-woven bags. However, this offset printing machine cannot offset print a whole roll of non-woven fabric. Therefore, it is necessary to cut the whole roll of non-woven fabric into sheets and then perform offset printing on the sheets in advance to complete the printing of logos or advertisements on the non-woven bag body. It is under this background that the present invention creatively designs a device specifically for forming sheet non-woven bags. Summary of the invention

[0026] Referring to the accompanying drawings, the present embodiment discloses a non-woven bag forming machine for sheet materials, which has a machine body, which includes a sheet material feeding device, a material transferring and folding device, an embossing device 2 and a hot handle device 1 in sequence. A flying head mechanism for sucking the sheet material and placing it on the sheet material feeding device is also provided at the front end of the sheet material feeding device. The flying head mechanism is a movable suction nozzle 36. Specifically, the suction nozzle 36 is installed on a moving frame 34. The moving frame 34 slides back and forth on the guide rail 33 under the action of a cylinder 35. After the suction nozzle 36 sucks the sheet material, it moves to the sheet material feeding device to be transported by it. The sheet material feeding device includes a driving roller 9 and a conveyor belt 10 covered on the driving roller 9. After the sheet material loaded with non-woven fabric falls onto the conveyor belt 10, it is transported by the conveyor belt 10. A correction device is provided at the connection between the sheet material feeding device and the mobile folding device. The correction device includes a photoelectric eye 20, a correction motor 25, a correction timing belt 24, a correction timing wheel (not marked in the figure), and a support block 22. A corresponding clamping member 21 is installed above the support block 22. The clamping member 21 is a cylinder, and the support block 22 and the clamping member 21 are simultaneously installed on a correction seat 23. The correction timing belt 24 is covered on the correction timing wheel. The correction seat 23 is fixed on the correction timing belt 24. The photoelectric eye 20 is electrically connected to the correction motor 25. When the deflection correction photoelectric eye 20 detects that the position of the sheet non-woven fabric is offset, the deflection correction motor 25 is activated, and the cylinder 21 is activated at the same time. The cylinder 21 is activated to clamp the sheet between the support block 22 and the pressure block on the push rod of the cylinder 21. After the deflection correction motor 25 is activated, it moves with the deflection correction synchronous belt 24 to achieve the purpose of deflection correction. The material moving and folding device includes a reciprocating first clamping component 17 and a folding plate 4. The folding plate 4 is arranged on one side of the reciprocating first clamping component 17. The reciprocating first clamping component 17 clamps the deflected sheet material and moves it. The material moving and folding device also includes a vertical plate 5, and the folding plate 4 has an inclined surface 43. The vertical plate 5 is connected with the inclined surface 43 so that the sheet material can pass smoothly; a retractable push plate 27 is arranged below the folding plate 4, and the push plate 27 is connected to the push plate cylinder 26 installed on the machine body, wherein a push plate guide rail 42 is provided on the machine body, and the push plate 27 is installed on the push plate guide rail 42 through a slider 41 to ensure that the push plate can be stably extended and retracted; a transmission wheel 7 is arranged at the front end of the vertical plate 5, and the transmission wheel 7 is connected to the transmission motor 8, and a liftable rolling pressure wheel 6 is correspondingly arranged above the transmission wheel 7, specifically, the rolling pressure wheel 6 is connected to the pressure wheel cylinder, or connected to other liftable airbags and other components.When the sheet material is transferred after deviation correction, the rolling pressure wheel 6 is first lowered and cooperates with the transmission wheel 7 to press the sheet material. The operation of the transmission motor 8 can convey the sheet material. Therefore, after the rolling pressure wheel 6 presses the sheet material, it does not affect the transmission of the sheet material. After the sheet material is conveyed, under the action of the vertical plate 5 and the rolling pressure wheel 6, the side of the sheet material is erected to 90 degrees. As the sheet material continues to be conveyed, it enters the inclined surface 43 of the folding plate 4. Since the inclined surface 43 has a certain length, as the sheet material continues to be conveyed, the side of the sheet material can be slowly folded. In order to avoid incomplete folding, the push plate cylinder 26 is used to push the push plate 27 to fold the side of the sheet material again, which can ensure that the side of the sheet material is completely folded. The embossing device 2 includes an embossing wheel 13 that can be raised and lowered and rotated. An ultrasonic welding head 39 that cooperates with the embossing wheel 13 is arranged below the embossing wheel 13, wherein the embossing wheel 13 is mounted on the rotating shaft of the embossing motor 40, and the mounting frame 46 of the embossing motor 40 is connected to the lifting cylinder 38. After the first clamping assembly 17 transfers the folded sheet material to the embossing device 2, it releases the sheet material and returns to its original position for the next clamping and transfer. When the sheet material is sent to the embossing device 2, the embossing wheel 13 rotates under the drive of the motor 40. At the same time, the motor 40 and the embossing wheel 13 descend under the drive of the lifting cylinder 38. Under the action of the ultrasonic welding head 39, the folded part of the sheet material is embossed and bonded. After the embossing and bonding are completed, the lifting cylinder 38 returns to its original position. A second reciprocating clamping assembly 16 is provided on one side of the handle ironing device 1. The second clamping assembly 16 clamps the embossed sheet material and moves it to the handle ironing device 1 to weld the bag handle at the folded position. The material transfer and folding device and the handle ironing device 1 have a transfer platform 44 on the same plane. Therefore, the folding of the sheet material and the handle ironing of this embodiment are all carried out in a flow-line operation on the same transfer platform. The handle ironing device described here, the applicant has applied for an invention patent on March 14, 2019, publication number: CN109732995A, name: handle ironing machine, the structure is the same as the handle ironing device of this application, and will not be repeated. After the second clamping assembly 16 transfers the sheet material into place, it returns immediately.

[0027] In the above technical solution, the first clamping assembly 17 and the second clamping assembly 16 both have a lower clamping portion 32, a bracket 28 connected to the lower clamping portion 32, and an upper clamping portion 30. The upper clamping portion 30 is hinged on the bracket 28 through a connecting rod 31, and one end of the connecting rod 31 is connected to the piston rod of the clamping cylinder 29 installed on the bracket 28. The lower clamping portion 32 is lower than the transfer platform 44. The upper clamping part 30 of the clamping assembly of this structure can be flipped, and the flipped upper clamping part 30 is also lower than the transfer platform 44. Therefore, when the sheet material moves to the transfer platform 44, the sheet material is above the lower clamping part. When the sheet material needs to be clamped, the upper clamping part 30 is flipped through the action of the clamping cylinder 29 and overlaps above the lower clamping part 32, just clamping and transferring the sheet material. After being transferred to the position, the upper clamping part is flipped back to its original position under the action of the clamping cylinder 29. At the same time, after the upper clamping part 30 returns to its original position, it is lower than the transfer platform 44 like the lower clamping part 32. Therefore, when the first clamping assembly 17 and the second clamping assembly 16 return to their positions, they will not be hindered by the sheet material or the transfer platform 44, and can work easily and freely to improve work efficiency.

[0028] A linear guide 18 is installed in the machine body, and the first clamping assembly 17 and the second assembly 16 reciprocate on the linear guide 18 through a slider 15. Specifically, the slider 15 is installed on a mounting seat 45, and the mounting seat 45 and the bracket 28. When the slider 15 moves, it drives all the components on the bracket 28 to move, so as to maintain the stability of the movement of the first and second clamping assemblies.

[0029] The brackets 28 of the first clamping assembly 17 and the second clamping assembly 16 are respectively connected to the corresponding reciprocating mechanisms through the mounting seat 45. There are many structures of such reciprocating mechanisms, and this embodiment only cites two, including but not limited to these two reciprocating mechanisms, wherein the reciprocating mechanism at the first clamping assembly 17 includes a motor 14, a synchronous belt 19 and a synchronous wheel (not shown in the figure) installed in the body, the synchronous belt 19 is wrapped on the synchronous wheel, and the mounting seat 45 is fixed on the synchronous belt 19; the reciprocating mechanism at the second clamping assembly 16 also includes a motor 11, a synchronous belt 12 and a synchronous wheel (not shown in the figure) installed in the body, and the mounting seat 45 of the second clamping assembly 16 is fixed on the synchronous belt 12. The two sets of reciprocating mechanisms are staggered to facilitate the second clamping assembly to smoothly receive the sheet material transferred by the first clamping assembly 17. This reciprocating mechanism can also have a motor and a screw rod, the motor is connected to the screw rod in a transmission manner, and the screw rod is screwed to the mounting seat. After the motor is activated, it can drive the mounting base to move back and forth.

[0030] From the above description, it can be known that the working process of the present invention is: the non-woven fabric cut into sheets is placed on the supporting platform 37, and the supporting platform will rise as the sheet material decreases, and its rise is generally completed by the cooperation of the chain and the slider. The sheet non-woven fabric is sent to the sheet feeding device by the feeder head mechanism; of course, a roll non-woven fabric can also be installed before that, and it is directly sent to the sheet material transfer feeding device after cutting, and then it is conveyed by the sheet feeding device, and then corrected by the correction mechanism, and then the sheet material is clamped and transferred by the first clamping component 17. During the transfer process, one side of the sheet material is folded by the folding plate 4, and the folded sheet material is sent to the embossing device 2, and the embossing device is used to emboss and bond it to form The non-woven bag opening is then transferred to the handle ironing device 1 through the second clamping component 16. After the handle ironing device welds the bag handle to the bag opening, the sheet material is finally sent to the three-dimensional bag forming device to form the bag body. The three-dimensional bag forming device here is an ordinary non-woven bag forming machine, such as the non-woven bag forming machine involved in the invention patent with authorization announcement number CN103817974B and name "Non-woven bag forming machine, i.e. bag body forming process", which can complete the forming process.

[0031] The material shifting and folding device, embossing device and ironing device can be arranged on both sides of the machine body, and can process the sheet-like non-woven fabric at the same time to improve its production efficiency.
