Description

Technical Field

[0001] This invention relates to the field of packaging bag processing technology, and more specifically to a packaging bag printing and cutting machine. Background Technology

[0002] Paper-plastic composite bags are made of plastic and kraft paper. The plastic layer is typically made of woven polypropylene (PP) or polyethylene (PE) as the base material, while the kraft paper is made of refined composite kraft paper. They are characterized by high strength, good water resistance, and an attractive appearance. They are one of the most popular packaging materials and are widely used in industries such as plastic raw materials, cement, feed, chemicals, and fertilizers.

[0003] Existing packaging bag printing devices, such as the invention patent document with authorization announcement number "CN113370582B" and patent name "A Packaging Bag Production and Printing Equipment", disclose a packaging bag printing device, including a processing flow table. A plastic strip roll is rotatably mounted on one end of the processing flow table. An installation plate is fixedly mounted on one side of the top of the processing flow table. A drive shaft is rotatably mounted on the top of the installation plate. A turntable is provided on the inner side of the installation plate. The turntable is fixedly connected to the drive shaft. A pushing protrusion is fixedly connected to the outer circumferential side of the turntable. The diameter of the pushing protrusion is larger than the diameter of the turntable.

[0004] The aforementioned patent document states that the packaging bags cannot be cut after printing. When consecutive packaging bags pass through the processing flow table, they can only be printed and cannot be cut after printing. The printed packaging bags need to be placed on an external device for cutting, which reduces production efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a packaging bag printing and cutting machine. This machine solves the technical problem mentioned in the background art: existing packaging bag printing devices cannot cut the packaging bags after printing. When continuous packaging bags pass through the processing flow table, they can only be printed but cannot be cut after printing. The printed packaging bags need to be placed on an external device for cutting, which reduces production efficiency.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] A packaging bag printing and cutting machine includes a base, a feeding roller on one side of the base, a guide block for guiding raw materials fixed on the base, two folding components for folding the raw materials on the base with the folding components located on one side of the guide block, two power rollers rotatably mounted on the base, a motor for driving the two power rollers to rotate, a printing roller and a rotating roller rotatably mounted on the base with the printing roller and the rotating roller located on the side of the power rollers away from the folding components, the printing roller and the rotating roller being vertically opposite each other, and a cutting component for cutting the raw materials on the base with the cutting component located on the side of the printing rollers away from the power rollers.

[0008] Working principle:

[0009] First, the operator places the raw material to be made into packaging bags on the feeding roller. Then, the operator pulls one end of the rolled raw material through the guide block and through the folding assembly. The folding assembly folds the raw material to form a packaging bag. After that, the folded packaging bag continues to pass between two power rollers. Then, the folded packaging bag passes between the printing roller and the rotating roller to print on the surface of the packaging bag. Finally, the cutting assembly cuts the packaging bag from a continuous state into individual packaging bags.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, it is equipped with a printing roller and a rotating roller. The packaging bag can pass between the printing roller and the rotating roller, and the printing roller can print on the surface of the packaging bag.

[0012] Secondly, it is equipped with a cutting component that can cut continuous packaging bags into individual packaging bags, so that continuous packaging bags do not need to be transported outside for cutting during the production of packaging bags.

[0013] Third, it is equipped with a folding component, which can fold the edges of sheet packaging bag raw materials into packaging bags, thereby facilitating subsequent printing and cutting of the packaging bags. Attached Figure Description

[0019] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] like Figure 1 and Figure 2 and Figure 3 As shown, a packaging bag printing and cutting machine includes a base 1, a feeding roller 2 on one side of the base 1, a guide block 3 for guiding raw materials fixed on the base 1, two folding components for folding the raw materials on the base 1 and located on one side of the guide block 3, two power rollers 4 rotatably mounted on the base 1, a motor 5 mounted on the base 1 for driving the two power rollers 4 to rotate, a printing roller 6 and a rotating roller 7 rotatably mounted on the base 1 and located on the side of the power rollers 4 away from the folding components, the printing roller 6 and the rotating roller 7 being vertically opposite each other, and a cutting component for cutting the raw materials on the base 1 and located on the side of the printing roller 6 away from the power rollers 4.

[0022] like Figure 1 As shown, a tension frame 8 is fixed on the base 1, and a plurality of rotating rollers 9 are rotatably mounted on the tension frame 8. A plurality of floating rollers 10 are rotatably mounted on the tension frame 8, and the floating rollers 10 correspond vertically to the rotating rollers 9. A first cylinder 11 is fixed on the base 1, and the telescopic end of the first cylinder 11 is used to push the plurality of floating rollers 10 to move.

[0023] First, the operator places the rolled packaging bag material on the feeding roller 2. Then, the operator pulls out one end of the material on the feeding roller 2 and makes the material pass through the rotating roller 9 and the floating roller 10 in sequence. When the operator needs to change the tension of the material, the operator can change the tension of the material by extending and retracting the telescopic end of the first cylinder 11.

[0024] like Figure 1 and Figure 2As shown, the guide block 3 has two mounting cavities 12, each of which is fixed with a first spring 13. Each of the two mounting cavities 12 is slidably provided with a sliding block 14, and the two sliding blocks 14 are fixedly connected to two corresponding first springs 13. The two sliding blocks 14 are vertically aligned, and each of the two sliding blocks 14 is rotatably provided with several auxiliary rollers 15.

[0025] like Figure 1 As shown, the folding assembly includes a fixing frame 16, a connecting plate 17, several rotating disks 18, and a second cylinder 19. The fixing frame 16 is fixedly mounted on the base 1, the connecting plate 17 is positioned above the fixing frame 16, the ends of the rotating disks 18 are rotatably mounted on the connecting plate 17, and the end of the rotating disk 18 away from the connecting plate 17 is close to the guide block 3. The second cylinder 19 is fixedly mounted on the base 1, and the extension end of the second cylinder 19 is fixedly connected to the connecting plate 17. Figure 1 As shown, the end of the guide block 3 is inclined, and the rotating disk 18 near the guide block 3 is placed at an angle. Figure 1 As shown, two conveying rollers 20 are rotatably mounted on the base 1, and the two conveying rollers 20 are vertically aligned.

[0026] When one end of the raw material is pulled to the guide block 3, the operator places the raw material under the guide block 3 and places the side edge of the raw material between the auxiliary rollers 15 on the two sliding blocks 14, thereby forming an arc shape at the end of the raw material to facilitate the subsequent processing of the raw material into a packaging bag. Then, the operator places both sides of the raw material between the guide block 3 and the rotating disk 18. Since the rotating disk 18 near the guide block 3 is placed at an angle, it cooperates with the inclined surface of the guide block 3 to bring the two sides of the raw material closer together and fold them inward. Then, the operator passes the raw material through the inclined rotating disk 18 and continues to pass through the rotating disk 18 in the normal state. The gap between the remaining rotating disks 18 becomes smaller and smaller, thereby folding the raw material and forming a bag shape. Then, the operator passes the folded packaging bag between the two conveying rollers 20.

[0027] like Figure 1 As shown, a first belt 21 is fitted onto the two power rollers 4, and the output end of the motor 5 is fixedly connected to one of the power rollers 4, as shown. Figure 1 As shown, an ink cartridge 22 is fixed on the base 1 and the ink cartridge 22 is located below the printing roller 6. When the printing roller 6 rotates, it can abut against the ink cartridge 22. A second belt 23 is sleeved on the rotating roller 7 and the printing roller 6. A third belt 24 is sleeved on the rotating roller 7 and one of the power rollers 4.

[0028] like Figure 1 and Figure 3 and Figure 4As shown, the cutting assembly includes a rotating rod 25, a ratchet 26, a connecting ring 27, a pawl 28, a limiting block 29, a connecting arm 30, a cutter 31, and a second spring 32. A mounting bracket 33 is fixedly mounted on the base 1. The rotating rod 25 is rotatably mounted on the mounting bracket 33. The ratchet 26 is rotatably mounted on the mounting bracket 33, and the rotating rod 25 slides through the center of the ratchet 26. The connecting ring 27 is rotatably mounted on the rotating rod 25. The pawl 28 is mounted on the connecting ring 27, and the pawl 28 connects to the ratchet 26. 6. The limiting block 29 is fixed on the connecting ring 27 and the end of the rotating rod 25 abuts against the limiting block 29. The connecting arm 30 is rotatably mounted on the connecting ring 27. The cutter 31 is rotatably connected to the connecting arm 30. The mounting bracket 33 is provided with a fixed ring 34, and the cutter 31 can move vertically on the ring 34. The second spring 32 is fixed on the ring 34 and is fixedly connected to the guide rod. The base 1 is provided with a blade groove 35, and the blade groove 35 corresponds vertically to the cutter 31. Figure 1 As shown, a fourth belt 36 is fitted onto the rotating rod 25 and the rotating roller 7.

[0029] The operator then passes the folded packaging bag between two power rollers 4, with the first belt 21 arranged in a figure-eight pattern. The bag continues between the rotating roller 7 and the printing roller 6, placing the raw material between the cutter 31 and the slot 35. The operator then starts the motor 5, which drives one of the power rollers 4 to rotate. The power roller 4, driven by the first belt 21, transports the packaging bag between the two power rollers 4. The power roller 4, via the third belt 24, drives the rotating roller 7 to rotate. When the packaging bag reaches the area between the printing roller 6 and the rotating roller 7, the printing roller 6 prints on the surface of the bag. The second belt 23 between the rotating roller 7 and the printing roller 6 is also arranged in a figure-eight pattern. As the printing roller 6 rotates, it comes into contact with the ink cartridge 22, allowing the ink to adhere to the printing roller 6, facilitating printing on the packaging bag surface. The printed packaging bag is then conveyed to… When the cutter 31 is below, the rotating roller 7 drives the rotating rod 25 to rotate via the fourth belt 36. When the rotating rod 25 rotates, it abuts against the limiting block 29 on the connecting ring 27, thereby driving the connecting ring 27 to rotate. When the connecting ring 27 rotates, the pawl 28 can continuously pass over the ratchet 26. A spring is provided between the pawl 28 and the connecting ring 27. The connecting ring 27 drives the connecting arm 30 to rotate. The rotation of the connecting arm 30 causes the cutter 31 to move vertically on the ring 34, thereby changing the second spring 32 from its natural state to its stretched state. Thus, the vertically moving cutter 31 can cut the packaging bag on the cutter groove 35. When the connecting ring 27 rotates to the bottom of the ratchet 26, since the second spring 32 is in the stretched state, the rotating block loses contact with the upper limit block 29 of the connecting ring 27, thereby changing the second spring 32 from the stretched state to its natural state, and thus the connecting ring 27 moves to its initial position.

[0030] Working principle:

[0031] First, the operator places the rolled packaging bag material on the feeding roller 2. Then, the operator pulls out one end of the material on the feeding roller 2 and makes the material pass through the rotating roller 9 and the floating roller 10 in sequence. When the operator needs to change the tension of the material, the operator can change the tension of the material by extending and retracting the telescopic end of the first cylinder 11.

[0032] When one end of the raw material is pulled to the guide block 3, the operator places the raw material under the guide block 3 and places the side edge of the raw material between the auxiliary rollers 15 on the two sliding blocks 14, thereby forming an arc shape at the end of the raw material to facilitate the subsequent processing of the raw material into a packaging bag. Then, the operator places both sides of the raw material between the guide block 3 and the rotating disk 18. Since the rotating disk 18 near the guide block 3 is placed at an angle, it cooperates with the inclined surface of the guide block 3 to bring the two sides of the raw material closer together and fold them inward. Then, the operator passes the raw material through the inclined rotating disk 18 and continues to pass through the rotating disk 18 in the normal state. The gap between the remaining rotating disks 18 becomes smaller and smaller, thereby folding the raw material and forming a bag shape. Then, the operator passes the folded packaging bag between the two conveying rollers 20.

[0033] The operator then passes the folded packaging bag between two power rollers 4, with the first belt 21 arranged in a figure-eight pattern. The bag is then passed between the rotating roller 7 and the printing roller 6, and the raw material is placed between the cutter 31 and the slot 35. The operator then starts the motor 5, which drives one of the power rollers 4 to rotate. The power roller 4, driven by the first belt 21, transports the packaging bag between the two power rollers 4. The power roller 4, via the third belt 24, drives the rotating roller 7 to rotate. When the packaging bag reaches the area between the printing roller 6 and the rotating roller 7, the printing roller 6 can print on the surface of the packaging bag. The second belt 23 between the rotating roller 7 and the printing roller 6 is also arranged in a figure-eight pattern. As the printing roller 6 rotates, it comes into contact with the ink cartridge 22, allowing the ink to adhere to the printing roller 6, facilitating printing on the surface of the packaging bag. When the finished packaging bag is conveyed to the cutter 31, the roller 7 drives the rotating rod 25 to rotate via the fourth belt 36. When the rotating rod 25 rotates, it abuts against the limit block 29 on the connecting ring 27, thereby driving the connecting ring 27 to rotate. When the connecting ring 27 rotates, the pawl 28 can continuously pass over the ratchet 26. The connecting ring 27 drives the connecting arm 30 to rotate. The rotation of the connecting arm 30 causes the cutter 31 to move vertically on the ring 34, thereby changing the second spring 32 from its natural state to its stretched state. Thus, the vertically moving cutter 31 can cut the packaging bag on the cutter groove 35. When the connecting ring 27 rotates to the bottom of the ratchet 26, since the second spring 32 is in the stretched state, the rotating block loses contact with the upper limit block 29 of the connecting ring 27, thereby changing the second spring 32 from the stretched state to its natural state, and thus the connecting ring 27 moves to its initial position.
