Description

Technical Field

[0001] This utility model relates to the field of composite bag production technology, and in particular to a composite bag production equipment. Background Technology

[0002] The basic manufacturing process of composite packaging bags consists of four steps: printing, lamination, slitting, and bag making. Among these, lamination and bag making are the key processes affecting the performance of the final product. When designing product packaging processes, in addition to the correct selection of various substrates, the selection of the adhesive used for lamination is also crucial. The choice must be based on the product's purpose, composition, post-processing conditions, and quality requirements. If the wrong adhesive is selected, no matter how advanced the lamination technology, it will lead to poor adhesion, weak bonding during post-processing, insecure lamination, leakage, and bag breakage, as per existing technologies.

[0003] Chinese patent document CN214927547U discloses a tension adjustment device for composite bag production, including two mounting plates mounted on a frame. Guide blocks slide vertically on the mounting plates, and a guide roller is rotatably mounted between the two guide blocks. The guide roller is located below the original packaging bag material. An adjustment mechanism for adjusting the height of the two guide blocks is provided at the upper end of the two mounting plates. This invention improves the production quality of packaging bags. However, like traditional methods, the position of the roller in the traditional composite process is always fixed, resulting in consistent composite strength between the roller and the substrate. In actual production, various substrates need to be composited. Due to variations in material and thickness, traditional rollers cannot meet the composite requirements of different substrates, easily leading to insufficient compression strength. Insufficient composite strength can cause white spots, bubbles, or even poor adhesion in the composite film, affecting the production quality of the composite bag. Therefore, we disclose a composite bag production equipment to meet the requirement of controlling the composite strength of the roller. Utility Model Content

[0004] The purpose of this invention is to provide a composite bag production equipment to solve the problem of insufficient composite strength of composite bag substrates mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite bag production equipment, comprising a frame and a lower hot press roller and an upper hot press roller for composite processing of a first substrate and a second substrate. Fixed columns are fixedly installed on the frame. Each pair of fixed columns has a sliding groove. A sliding rod is inserted through the sliding groove and slidably connected to the fixed column. A lifting assembly is also provided on the sliding rod. The lifting assembly is used to adjust the position of the press roller. The lifting assembly includes a first pressing frame slidably sleeved on the sliding rod, and the first pressing frame is slidably engaged in the sliding groove. A base plate and a second pressing frame are fixedly connected to both ends of the sliding rod, respectively. A pair of support columns are fixedly installed on one side of the frame. Fixed seats are fixedly installed on each pair of support columns. A rectangular frame is rotatably connected between the pair of fixed seats via bearings. A tensioning assembly is also provided between the support columns and the rectangular frame. The tensioning assembly includes a pair of tensioning rollers rotatably mounted on the rectangular frame and a semi-circular gear fixedly mounted on one side of the rectangular frame.

[0006] Preferably, a lower connecting rod is rotatably mounted on the top of the base plate, and a rotating rod is rotatably connected to the top of the lower connecting rod via a rotating shaft. The rotating rod is rotatably connected to the bottom of the first pressure frame via an upper connecting rod, and the rotating rod, the upper connecting rod, and the lower connecting rod are used in conjunction.

[0007] Preferably, a through groove is provided on one side of the frame to facilitate the passage of the first pressure frame.

[0008] Preferably, a placement slot is provided on one side of the through slot, a first motor is fixedly installed in the placement slot, a first short shaft is fixedly connected to the output end of the first motor, and one end of the first short shaft passes through the placement slot and is fixedly connected to the middle of the rotating rod.

[0009] Preferably, the lower hot press roller and the upper hot press roller are rotatably mounted on the first press frame and the second press frame, respectively.

[0010] Preferably, a second motor is fixedly installed on the support column, and a second short shaft is fixedly connected to the output end of the second motor. The second short shaft passes through the support column and is fixedly connected to the drive gear. The drive gear is located below the semi-circular gear and meshes with the semi-circular gear.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model has a reasonable structure. In actual use, starting the first motor drives the rotating rod to swing, causing the rotating rod to drive the upper and lower connecting rods to reciprocate. By controlling the forward and reverse rotation of the first motor, under the guidance of the slide groove and slide rod, the upper and lower hot press rollers move towards each other or away from each other along the slide rod, and the positions of the upper and lower hot press rollers are adjusted simultaneously. Existing laminating machines require inserting the substrate film between the press rollers when laminating the substrate, but due to the thickness of the substrate itself... The previous method was difficult to insert the substrate into the press roller. This application solves this problem by controlling the lifting component to open the upper and lower hot press rollers, making it easier for workers to insert the substrate to be laminated, thus improving work efficiency. Then, according to the different substrate lamination requirements, the workers can control the forward and reverse rotation of the first motor to adjust the position of the upper and lower hot press rollers, thereby controlling the lamination strength of the press rollers on the substrate. This avoids the occurrence of white spots, bubbles, or even poor pressing on the composite film, improving the lamination quality of the substrate and facilitating subsequent production and manufacturing.

[0013] 2. In this utility model, due to the thickness variation of different substrates, the substrate film roll is prone to uneven winding tension, resulting in one end being loose and the other tight. When the difference in tightness between the two ends of the substrate film roll is large, the substrate film will swing significantly up and down and left and right during production, easily causing wrinkles, which seriously affects the production quality of the packaging bag. When the difference in tightness between the two ends of the substrate film roll is large, the second motor is started. The second motor drives the drive gear to rotate, which in turn drives the semi-circular gear to rotate, thereby gradually rotating the rectangular frame. This causes the tensioning roller to gradually tighten the substrate film on it, preventing wrinkles from forming in the composite film and improving the product quality of the composite film.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1-4The composite bag production equipment shown includes a frame 1 and a lower hot press roller 6 and an upper hot press roller 7 for composite processing of a first substrate and a second substrate. Fixed columns 2 are fixedly installed on the frame 1. Each pair of fixed columns 2 has a sliding groove 3. A sliding rod 20 is inserted through the sliding groove 3 and slidably connected to the fixed column 2. A lifting assembly is also provided on the sliding rod 20 for adjusting the position of the press roller. The lifting assembly includes a first pressing frame 4 slidably sleeved on the sliding rod 20 and slidably engaged within the sliding groove 3. The two sides of the sliding rod 20... The frame 1 is fixedly connected to a base plate 12 and a second pressure frame 5 at each end. A pair of support columns 13 are fixedly installed on one side of the frame 1. Each support column 13 is fixedly mounted with a fixed seat 15. A rectangular frame 18 is rotatably connected between the pair of fixed seats 15 via a bearing. A tensioning assembly is also provided between the support columns 13 and the rectangular frame 18. The tensioning assembly includes a pair of tensioning rollers 21 rotatably mounted on the rectangular frame 18 and a semi-circular gear 17 fixedly mounted on one side of the rectangular frame 18. In existing laminating machines, when laminating substrates, the substrate film needs to be inserted between the pressure rollers. However, due to the thickness of the substrate itself, it is difficult to insert the substrate into the press roller. This application addresses this by incorporating a lifting assembly, which allows for simultaneous adjustment of the positions of the upper and lower hot press rollers 7 and 6. In practical use, the lifting assembly can open the upper and lower hot press rollers 7 and 6, facilitating the insertion of the substrate to be laminated and improving work efficiency. Furthermore, based on the different substrate lamination requirements, the operator can adjust the positions of the upper and lower hot press rollers 7 and 6 to control the lamination strength of the substrate, preventing white spots and bubbles from forming on the laminated film. This prevents issues like incomplete lamination and improves the composite quality of the substrate, facilitating subsequent manufacturing. Due to variations in thickness between different substrates, the substrate film roll is prone to uneven tension during winding, resulting in one end being loose and the other tight. When the tension difference between the two ends of the substrate film roll is significant, the substrate film also swings more widely during production, easily causing wrinkles. This severely affects the production quality of the packaging bags. By setting up tensioning components, the substrate film can be tensioned, preventing wrinkles from forming in the composite film and improving the product quality of the composite film.

[0021] Furthermore, in this embodiment, as Figures 1-3As shown, a lower connecting rod 11 is rotatably mounted on the top of the base plate 12. A rotating rod 9 is rotatably connected to the top of the lower connecting rod 11 via a rotating shaft. An upper connecting rod 10 is rotatably connected to the bottom of the first pressure frame 4. The rotating rod 9, upper connecting rod 10, and lower connecting rod 11 work together. A through groove 19 is provided on one side of the frame 1 to facilitate the passage of the first pressure frame 4. A placement groove is provided on one side of the through groove 19. A first motor 8 is fixedly installed in the placement groove. A first short shaft is fixedly connected to the output end of the first motor 8. One end of the first short shaft passes through the placement groove and is fixedly connected to the middle of the rotating rod 9. A lower hot press roller 6 and an upper hot press roller 7 are rotatably mounted on the first pressure frame 4 and the second pressure frame 5, respectively. In actual use, starting the first motor 8 causes the rotating rod 9 to swing, causing the rotating rod 9 to drive the upper connecting rod 11 and the lower connecting rod 10 to reciprocate. By controlling the forward and reverse rotation of the first motor 8, the sliding groove... Guided by slide bar 20, the upper hot press roller 7 and the lower hot press roller 6 move in opposite directions or backwards along slide bar 20, and their positions are adjusted simultaneously. In existing laminating machines, when laminating substrates, the substrate film needs to be inserted between the press rollers. However, due to the thickness of the substrate itself, it is difficult to insert the substrate into the press roller. This application can open the upper hot press roller 7 and the lower hot press roller 6 by controlling the lifting component, making it easier for the operator to insert the substrate to be laminated, thus improving work efficiency. Then, according to the different substrate lamination requirements, the operator can adjust the position of the upper hot press roller 7 and the lower hot press roller 6 by controlling the first motor 8 to rotate forward and reverse, thereby controlling the lamination strength of the press roller on the substrate and avoiding the occurrence of white spots, bubbles, or even poor pressing on the laminated film. This improves the lamination quality of the substrate and facilitates subsequent production and manufacturing.

[0022] Furthermore, in this embodiment, as Figure 4 As shown, a second motor 14 is fixedly installed on the support column 13. The output end of the second motor 14 is fixedly connected to a second short shaft. The second short shaft passes through the support column 13 and is fixedly connected to the drive gear 16. The drive gear 16 is located below the semi-circular gear 17 and meshes with the semi-circular gear 17. Due to the thickness variation of different substrates, the substrate film roll is prone to being loose at one end and tight at the other due to uneven winding tension. When the tension difference between the two ends of the substrate film roll is large, the substrate film will swing up and down and left and right during the production process, which is prone to wrinkles, thus seriously affecting the production quality of the packaging bag. When the tension difference between the two ends of the substrate film roll is large, the second motor 14 is started. The second motor 14 drives the drive gear 16 to rotate, the drive gear 16 drives the semi-circular gear 17 to rotate, and then drives the rectangular frame 18 to rotate gradually, so that the tensioning roller 21 gradually tensions the substrate film on it, avoiding wrinkles in the composite film and improving the product quality of the composite film.

[0023] The working principle of this practical application is as follows: In actual use, the first motor 8 is started, driving the rotating rod 9 to swing. This causes the rotating rod 9 to drive the upper connecting rod 11 and the lower connecting rod 10 to reciprocate. By controlling the forward and reverse rotation of the first motor 8, under the guidance of the slide groove 3 and the slide rod 20, the upper hot press roller 7 and the lower hot press roller 6 move in opposite directions or away from each other along the slide rod 20. The positions of the upper hot press roller 7 and the lower hot press roller 6 are adjusted simultaneously. Existing laminating machines require inserting the substrate film between the press rollers during the lamination operation. However, due to the substrate itself... Due to the thickness of the substrate, it is difficult to insert the substrate into the press roller. This application can open the upper hot press roller 7 and the lower hot press roller 6 by controlling the lifting component, so that the operator can insert the substrate to be laminated, thus improving work efficiency. Then, the operator can adjust the position of the upper hot press roller 7 and the lower hot press roller 6 by controlling the forward and reverse rotation of the first motor 8 according to the different substrate lamination requirements, so as to control the lamination strength of the press roller on the substrate, avoid the occurrence of white spots, bubbles, or even poor pressing on the composite film, improve the lamination quality of the substrate, and facilitate subsequent production and manufacturing.

[0024] Due to variations in the thickness of different substrates, the substrate film roll is prone to uneven tension during winding, resulting in one end being loose and the other tight. When the tension difference between the two ends of the substrate film roll is significant, the substrate film will also swing more wildly during production, easily causing wrinkles. This seriously affects the production quality of the packaging bags. When a significant tension difference occurs between the two ends of the substrate film roll, the second motor 14 is activated. The second motor 14 drives the drive gear 16 to rotate, which in turn drives the semi-circular gear 17 to rotate, thereby gradually rotating the rectangular frame 18. This causes the tensioning roller 21 to gradually tighten the substrate film on it, preventing wrinkles from forming in the composite film and improving the product quality of the composite film.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
