Description

Technical Field

[0001] The present application relates to the technical field of packaging bag production equipment, and in particular to a slitting module and a packaging bag production device. Background Art

[0002] During the production of packaging bags, they need to be cut according to their size. The common cutting method is to stack two layers of plastic film, then heat the cutter and cut the double layers of plastic film.

[0003] When the packaging bag production device cuts the double-layer plastic film in the above-mentioned manner, only one side of the plastic film is in direct contact with the heated cutter, and the plastic film on the other side needs to be cut by the cutter after the cutter cuts the plastic film on one side. Since the cutter cuts the plastic film on one side before cutting the plastic film on the other side, if the cutter temperature is low, the cutter will not be in contact with the double-layer plastic film for a long time, and if the cutter temperature is increased, the anti-stick coating of the cutter will fall off. In other words, the cutter at the right temperature needs to be in contact with the double-layer plastic film for a long time. Therefore, it is easy to cause wrinkles and hot-melt wire drawing on the cut of the double-layer plastic film, and the double-layer plastic film will stick to the knife after hot melting, and the cutter needs to be cleaned, resulting in poor production quality and low efficiency.

[0033] See Figures 1 to 3 , shows a schematic structural diagram of a slitting module in an embodiment of the present application. The slitting module is used to slit a double-layer plastic film. The slitting module includes a mounting mechanism 100, a tool mechanism 200, and a supporting mechanism 300. The mounting mechanism 100 includes a first mounting frame 120 and a second mounting frame 130, which are arranged opposite to each other. The tool mechanism 200 is movably mounted on the first mounting frame 120. The tool mechanism 200 includes a first guide assembly 210, a first drive unit 220, a cutter 230, and a first heating assembly 240. The first guide assembly 210 is movably mounted on the first mounting frame 120. The first drive unit 220 is mounted on the first mounting frame 120. The first drive unit 220 is drivingly connected to the first guide assembly 210. The cutter 230 is mounted on the first guide assembly 210. The first heating assembly 240 is connected to the cutter 230. The supporting mechanism 300 can be movably set on the second mounting frame 130. The supporting mechanism 300 includes a second guide assembly 310, a second drive unit 320, a support 330 and a second heating assembly 340. The second guide assembly 310 can be movably mounted on the second mounting frame 130. The second drive unit 320 is mounted on the second mounting frame 130. The second drive unit 320 is driven and connected to the second guide assembly 310. The support 330 is mounted on the second guide assembly 310. The second heating assembly 340 is connected to the support 330. The cutter 230 and the support 330 are relatively spaced apart so that the double-layer plastic film 10 is arranged between the cutter 230 and the support 330.

[0034] The slitting module described in the embodiment of the present application is configured by relatively arranging a tool mechanism 200 and a supporting mechanism 300 on a first mounting frame 120 and a second mounting frame 130, wherein the first driving unit 220 drives the first guide assembly 210 to move, and the second driving unit 320 drives the second guide assembly 310 to move, so that the cutter 230 installed on the first guide assembly 210 and the supporting member 330 installed on the second guide assembly 310 move toward each other. The plastic film is folded to form a double-layer plastic film 10. The fold line of the double-layer plastic film 10 is the direction of movement of the double-layer plastic film. The double-layer plastic film 10 is positioned between a cutter 230 and a carrier 330. The cutting line between the cutter 230 and the carrier 330 is perpendicular to the fold line of the double-layer plastic film 10. A first heating element 240 heats the cutter 230. The cutter 230 then abuts the double-layer plastic film 10 against the carrier 330 to cut and bond the cuts. The carrier mechanism 300 is also provided with a second heating element 340 to heat the carrier 330, thereby preheating the plastic film near the carrier 330, allowing the cutter 230 to complete the cutting more quickly. After the double-layer plastic film 10 is cut and bonded twice, it forms a packaging bag with bonded sides, a folded bottom, and an open top.

[0035] The slitting module described in the embodiment of the present application heats the carrier 330 by setting a second heating component 340 to preheat the double-layer plastic film 10, thereby reducing the temperature required for cutting by the cutter 230 and reducing the time that the cutter 230 is in close contact with the double-layer plastic film 10 during the slitting process, thereby reducing wrinkles and hot melt wiredrawing at the cut of the double-layer plastic film 10. There is no need to frequently clean the cutter, and the processing time is also shorter, which has the advantages of good processing quality and high efficiency.

[0036] In an optional embodiment, the mounting mechanism 100 further includes a base 110 and a top beam 140, wherein the first mounting frame 120 and the second mounting frame 130 are both connected to the base 110, and the two ends of the top beam 140 are respectively connected to the top of the first mounting frame 120 and the top of the second mounting frame 130. By providing the base 110 and the top beam 140, the overall strength of the mounting mechanism 100 is enhanced and the stability in use is improved.

[0037] like Figure 2 and Figure 3As shown, in some embodiments, the first guide assembly 210 includes a first mounting seat 211, a first guide shaft 212, and a first linear bearing 213. The first linear bearing 213 is disposed on the first mounting bracket 120. The first guide shaft 212 is movably disposed on the first linear bearing 213. The first guide shaft 212 is disposed along a first direction of the slitting module. One end of the first guide shaft 212 facing the supporting mechanism 300 is connected to the first mounting seat 211. The cutter 230 is mounted on a side of the first mounting seat 211 facing the supporting mechanism 300. The first direction of the slitting module is perpendicular to the blade of the cutter 230.

[0038] In this embodiment, the first linear bearing 213 is set on the first mounting frame 120, and then the first driving unit 220 drives the first guide shaft 212 and the cutter 230 to move on the first linear bearing 213, so that the moving direction of the cutter 230 is limited by the first guide assembly 210. When the cutter 230 cuts and bonds the double-layer plastic film 10, the movement accuracy of the first guide shaft 212 can be improved by the first linear bearing 213.

[0039] Similarly, if Figure 2 and Figure 3 As shown, the second guide assembly 310 includes a second mounting base 311, a second guide shaft 312, and a second linear bearing 313. The second linear bearing 313 is mounted on the second mounting frame 130. The second guide shaft 312 is movably mounted on the second linear bearing 313. The second guide shaft 312 is arranged along the first direction of the slitting module. The end of the second guide shaft 312 facing the tool mechanism 200 is connected to the second mounting base 311. The carrier 330 is mounted on the side of the second mounting base 311 facing the tool mechanism 200. By mounting the second linear bearing 313 on the second mounting frame 130, and then the second driving unit 320 drives the second guide shaft 312 and the carrier 330 to move on the second linear bearing 313, the movement direction of the carrier 330 is defined by the second guide assembly 310. When the double-layer plastic film 10 is slid and bonded, the reciprocating motion abuts the double-layer plastic film 10, thereby providing support for the cutter 230 during slitting and bonding. The second linear bearing 313 improves the movement accuracy of the second guide shaft 312.

[0040] In an optional embodiment, the first mounting frame 120 is provided with a first guide hole, the first guide shaft 212 is movably arranged in the first guide hole, the second mounting frame 130 is provided with a second guide hole, the second guide shaft 312 is movably arranged in the second guide hole, and the first guide hole and the second guide hole are arranged relative to each other along the first direction of the cutting module, so that the first guide shaft 212 can move on the first mounting frame 120, and the second guide shaft 312 can move on the second mounting frame 130.

[0041] In an optional embodiment, if Figure 2 As shown, the first driving unit 220 includes a first driving cylinder 221 and a first position sensor. The first driving cylinder 221 is mounted on the first mounting frame 120. The power output end of the first driving cylinder 221 is connected to the first mounting seat 211. The first driving cylinder 221 is used to drive the first mounting seat 211 to move along the first direction of the slitting module. The first position sensor is mounted on the first mounting frame 120 and is used to detect the position of the first mounting seat 211 relative to the first mounting frame 120. By connecting the first driving cylinder 221 to an air source, the output end of the first driving cylinder 221 is controlled to drive the first mounting seat 211 and the cutter 230 to move along the first direction of the slitting module. The first position sensor can detect the position of the first mounting seat 211, thereby adjusting the position of the cutter 230 based on the detection result, thereby improving the accuracy of driving the cutter 230.

[0042] Similarly, if Figure 2 As shown, the second driving unit 320 includes a second driving cylinder 321 and a second position sensor. The second driving cylinder 321 is mounted on the second mounting frame 130. The power output end of the second driving cylinder 321 is connected to the second mounting seat 311. The second driving cylinder 321 is used to drive the second mounting seat 311 to move along the first direction of the slitting module. The second position sensor is mounted on the second mounting frame 130 and is used to detect the position of the second mounting seat 311 relative to the second mounting frame 130. By connecting the second driving cylinder 321 to an air source, the output end of the second driving cylinder 321 is controlled to drive the second mounting seat 311 and the supporting member 330 to move along the first direction of the slitting module, so that the supporting member 330 and the cutter 230 move toward each other. In addition, the second position sensor can detect the position of the second mounting seat 311, thereby adjusting the position of the supporting member 330 based on the detection result, thereby improving the accuracy of driving the cutter 230.

[0043] In an optional embodiment, if Figure 2 and Figure 3As shown, the first heating assembly 240 includes a first heating element 241 and a first temperature sensor. The first heating element 241 is connected to the cutter 230. The first temperature sensor is mounted on the cutter 230 and is used to detect the temperature of the cutter 230. The second heating assembly 340 includes a second heating element 341 and a second temperature sensor. The second heating element 341 is mounted inside the carrier 330. The second temperature sensor is mounted inside or outside the carrier 330 and is used to detect the temperature of the carrier 330. By providing the first heating element 241 on the cutter 230 and the second heating element 341 on the carrier 330, the cutter 230 and the carrier 330 are heated. The carrier 330 abuts against the double-layer plastic film 10 to preheat. This allows the double-layer plastic film 10 to reach the cutting temperature more quickly when the cutter 230 is used to slit and bond the double-layer plastic film 10, reducing the slitting and bonding time and improving the slitting and bonding quality of the double-layer plastic film 10. Moreover, the temperatures of the cutter 230 and the carrier 330 are monitored by the first temperature sensor and the second temperature sensor, so that the first heating element 241 and the second heating element 341 are adjusted according to the detection results, so that the heating temperature of the cutter 230 and the carrier 330 is more accurate, thereby improving the quality and efficiency of slitting and bonding.

[0044] In an exemplary embodiment, the first heating element 241 and the second heating element 341 are both electric heating tubes. The electric heating tube is an electrical component that converts electrical energy into thermal energy and has the advantage of being easy to use.

[0045] In an optional embodiment, if Figure 2 and Figure 3 As shown, the tool mechanism 200 also includes a pre-stressing component 250, which includes a fixed column 251, an elastic damping member 252 and a pre-stressing member 253. The fixed column 251 is arranged on the first mounting seat 211 on both sides of the cutter 230, and the pre-stressing member 253 is movably arranged at the end of the fixed column 251 away from the first mounting seat 211. One end of the elastic damping member 252 is connected to the pre-stressing member 253, and the other end of the elastic damping member 252 abuts the first mounting seat 211. The projection of the pre-stressing member 253 in the first direction of the cutting module corresponds to the position of the second mounting frame 130. By arranging multiple fixing columns 251 on the first mounting seat 211, the fixing columns 251 are located on both sides of the cutter 230, and then pre-pressing parts 253 are respectively arranged on the fixing columns 251 on both sides, and the pre-pressing parts 253 are connected by elastic damping parts 252. When the first driving unit 220 drives the first mounting seat 211 to move toward the supporting member 330, the pre-pressing parts 253 first contact the double-layer plastic film 10, and then press the double-layer plastic film 10 against both sides of the supporting member 330, pre-pressing the double-layer plastic film 10, so that the double-layer plastic film 10 on the supporting member 330 is smoother, thereby improving the quality of the cutter 230 in cutting and bonding the double-layer plastic film 10.

[0046] In an optional embodiment, the slitting module further includes a controller, and the first drive unit 220, the second drive unit 320, the first heating component 240, and the second heating component 340 are all electrically connected to the controller. By setting the controller, the controller can be used to control the first heating component 240 to heat the cutter 230 to a suitable cutter temperature, and the second heating component 340 to heat the carrier 330 to a suitable compensation temperature, and then control the first drive unit 220 and the second drive unit 320 to drive the cutter 230 and the carrier 330 to move toward each other to the processing position, so that the cutter 230 and the carrier 330 synchronously reach the double-layer plastic film 10 for extrusion, thereby cutting the double-layer plastic film 10, and then control the first drive unit 220 and the second drive unit 320 to drive the cutter 230 and the carrier 330 to move back to the initial position in opposite directions, completing one slitting and bonding.

[0047] In an optional embodiment, the surface of the cutter 230 is provided with an anti-stick coating. Specifically, the anti-stick coating is Teflon. During the high-temperature cutting process, the molten double-layer plastic film 10 tends to adhere to the cutter surface, resulting in burrs, stringing, or film tears. The anti-stick coating prevents the molten double-layer plastic film 10 from adhering to the cutter, ensuring a smooth cutting process and a smooth, adhesion-free cut.

[0048] In an optional embodiment, if Figure 3 As shown, a cushion pad 331 is provided on the side of the carrier 330 facing the cutter 230. By providing cushion pad 331 on the surface of the carrier 330, it provides flexible support for the double-layer plastic film 10 during the cutting process. This, in conjunction with the cutter 230, creates a combined shearing and squeezing action, resulting in a smoother cut edge and reducing stringing or burrs. Compared to cutting directly on the rigid carrier 330, cushion pad 331 can reduce the cut burr rate by over 50%.

[0049] In an exemplary embodiment, the buffer pad 331 is a silicone pad.

[0050] In an optional embodiment, if Figure 3 As shown, the support mechanism 300 further includes a high-temperature cloth 332, which is disposed on the surface of the buffer pad 331. By arranging the high-temperature cloth 332 in conjunction with the buffer pad 331, the high-temperature cloth 332 evenly distributes the temperature of the cutter 230, forming an anti-sticking combination with the buffer pad 331, further improving the slitting and gluing efficiency.

[0051] In an optional embodiment, the tool mechanism 200 further includes an air blowing component, which is disposed on one side of the cutter 230 and is used to cool the double-layer plastic film 10 after cutting and bonding.

[0052] Furthermore, the tool mechanism 200 also includes a travel switch and a trigger member. The trigger member is arranged on the first mounting seat 211, and the travel switch is arranged on the first mounting frame 120. When the first mounting seat 211 moves, the trigger member is driven to move, thereby triggering the switch to be opened or closed, thereby controlling the opening or closing of the blowing component, and automatically cooling down when the tool mechanism 200 retracts.

[0053] On the other hand, the present application also provides a packaging bag production device, including the slitting module described in any of the above embodiments, which is used to slitting and gluing a double-layer plastic film 10. The slitting module heats the carrier 330 by providing a second heating component 340, thereby preheating the double-layer plastic film 10, reducing the time that the cutter 230 is in close contact with the double-layer plastic film 10 during the slitting and gluing process, thereby reducing wrinkles and hot melt stringing on the cut of the double-layer plastic film 10. In addition, there is no need to frequently clean the cutter, and the processing time is shortened, which has the advantages of good processing quality and high efficiency.

[0054] In an optional embodiment, the packaging bag production device further includes a heat sealing module, which is used to seal the opening of the slit and bonded double-layer plastic film 10.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
