Description

Technical Field

[0001] The present invention relates to the technical field related to packaging machinery, and in particular to a high-speed transverse sealing device and a working method thereof. Background Art

[0002] Vertical packaging machines are usually equipped with a transverse sealing device for transversely sealing the packaging film below the former. The two heated transverse sealing blocks of the transverse sealing device clamp the packaging film, causing the packaging film to adhere due to the heat. The upper and lower seals of the existing bagged snacks, such as potato chips and shrimp sticks, are transversely sealed by the transverse sealing device. For thinner packaging films, the two transverse sealing blocks of the transverse sealing device clamp the packaging film for a short time to achieve heat sealing. For thicker packaging films, the two transverse sealing blocks of the transverse sealing device need to clamp the packaging film for a longer time. Before completing the transverse sealing, the packaging film needs to wait for a long time. The packaging film can only continue to move downward after the transverse sealing device completes the transverse sealing. The waiting time of the packaging film is one of the important factors restricting the packaging efficiency of the entire packaging machine. To this end, we propose a high-speed transverse sealing device and its working method. Summary of the invention

[0005] To further explain, the transverse sealing assembly includes a first driven translation member, a connecting rod mechanism, a driven shaft, a transverse sealing driving member, a first push-pull mechanism, a second push-pull mechanism, a first translation seat, a second translation seat, and a first transverse sealing pressure block and a second transverse sealing pressure block fixedly mounted on the first translation seat and the second translation seat, respectively; the first cam member is connected to the first driven translation member, the first driven translation member is movably connected to the input end of the connecting rod mechanism, the output end of the connecting rod mechanism is fixedly connected to the driven shaft, the transverse sealing driving member is fixedly arranged on the driven shaft, and the transverse sealing driving member is respectively hinged to the first push-pull rod of the first push-pull mechanism and the second push-pull rod of the second push-pull mechanism.

[0006] To further explain, the first cam member is a cylindrical cam, the first driven translation member is provided with a roller moving along a groove of the first cam member, and the first cam member drives the first driven translation member to perform horizontal reciprocating movement through the roller.

[0007] It is further explained that the lifting drive assembly is a cam mechanism or a crank-connecting rod mechanism.

[0008] To further explain, the connecting rod mechanism includes a first connecting rod, a second connecting rod, a third connecting rod, and a pin shaft. The first connecting rod is rotatably set on the pin shaft, one end of the first connecting rod is movably connected to the first driven translation member, the two ends of the second connecting rod are respectively hinged to one end of the third connecting rod and the other end of the first connecting rod, and the other end of the third connecting rod is fixedly connected to the driven shaft.

[0009] To further explain, the first push-pull mechanism includes a compression spring, a first movable plate, and a first connecting rod. The two ends of the first push-pull rod are respectively hinged to the transverse sealing drive member and the hinge seat of the first movable plate. The two ends of the first connecting rod are respectively fixedly connected to the first movable plate and the first translation seat. One end of the compression spring is fixedly set, and the other end of the compression spring is in contact with the first movable plate.

[0010] To further explain, the second push-pull mechanism includes a second connecting rod, both ends of which are respectively hinged to the transverse sealing drive member and a hinged seat at one end of the second connecting rod, and the other end of the second connecting rod is fixedly connected to the second translation seat.

[0011] Further, it is also included a cutting component arranged at the first translation seat or the second translation seat, and the cutting component is used to cut the heat-sealed packaging film.

[0012] A working method of a high-speed transverse sealing device, based on the above-mentioned high-speed transverse sealing device, comprises the following steps:

[0013] A1. The driving motor synchronously drives the first cam member and the lifting driving member of the lifting driving assembly to rotate through the transmission shaft, the first cam member drives the transverse sealing assembly, and the lifting driving member drives the lifting transverse sealing unit to move upward from the lowest position to the highest position;

[0014] At the same time, when the first cam member rotates, it first drives the first driven translation member to move horizontally in a positive direction, and the first driven translation member drives the horizontal sealing driving member to rotate positively through the connecting rod mechanism, and the horizontal sealing driving member synchronously drives the first push-pull mechanism and the second push-pull mechanism, and the first push-pull mechanism and the second push-pull mechanism drive the first horizontal sealing pressure block and the second horizontal sealing pressure block to separate from each other;

[0015] A2. When the first transverse sealing block and the second transverse sealing block are separated from each other to the maximum distance, the first cam member continues to rotate and drives the first driven translation member to move horizontally in the opposite direction. The first driven translation member drives the transverse sealing driving member to rotate in the opposite direction through the connecting rod mechanism. The transverse sealing driving member drives the first transverse sealing block and the second transverse sealing block to merge with each other through the first push-pull mechanism and the second push-pull mechanism, thereby clamping the packaging film. When the lifting transverse sealing unit moves up to the highest position, the packaging film begins to be heat-sealed transversely.

[0016] A3, the driving motor continues to synchronously drive the first cam member and the lifting driving member of the lifting driving assembly to rotate through the transmission shaft, and the lifting horizontal sealing unit moves downward from the highest position to the lowest position. Under the action of the first cam member, the first driven translation member first remains in a fixed state, and the first horizontal sealing block and the second horizontal sealing block remain in a state of being merged with each other. While the packaging film moves downward synchronously with the lifting horizontal sealing unit, it also continues to remain in a state of being transversely heat-sealed by the first horizontal sealing block and the second horizontal sealing block;

[0017] A4. The driving motor continues to synchronously drive the first cam member and the lifting driving member of the lifting driving assembly to rotate through the transmission shaft. The first cam member then drives the first driven translation member to move horizontally in a positive direction. The first driven translation member drives the transverse sealing driving member to rotate positively through the connecting rod mechanism. The transverse sealing driving member synchronously drives the first push-pull mechanism and the second push-pull mechanism. The first push-pull mechanism and the second push-pull mechanism drive the first transverse sealing block and the second transverse sealing block to separate from each other, thereby loosening the packaging film. The lifting and transverse sealing unit moves down to the lowest position, and the transmission shaft completes a 360° rotation. Thereafter, step A1 is repeated in a cycle.

[0018] A working method of a high-speed transverse sealing device, based on the above-mentioned high-speed transverse sealing device and cutting assembly, comprises the following steps:

[0019] B1. The driving motor synchronously drives the first cam member and the lifting driving member of the lifting driving assembly to rotate through the transmission shaft, the first cam member drives the transverse sealing assembly, and the lifting driving member drives the lifting transverse sealing unit to move upward from the lowest position to the highest position;

[0020] At the same time, when the first cam member rotates, it first drives the first driven translation member to move horizontally in a positive direction, and the first driven translation member drives the horizontal sealing driving member to rotate positively through the connecting rod mechanism, and the horizontal sealing driving member synchronously drives the first push-pull mechanism and the second push-pull mechanism, and the first push-pull mechanism and the second push-pull mechanism drive the first horizontal sealing pressure block and the second horizontal sealing pressure block to separate from each other;

[0021] B2. When the first transverse sealing block and the second transverse sealing block are separated from each other to the maximum distance, the first cam member continues to rotate and drives the first driven translation member to move horizontally in the opposite direction. The first driven translation member drives the transverse sealing driving member to rotate in the opposite direction through the connecting rod mechanism. The transverse sealing driving member drives the first transverse sealing block and the second transverse sealing block to merge with each other through the first push-pull mechanism and the second push-pull mechanism, thereby clamping the packaging film. When the lifting transverse sealing unit moves up to the highest position, the packaging film begins to be heat-sealed transversely.

[0022] B3, the driving motor continues to synchronously drive the first cam member and the lifting driving member of the lifting driving assembly to rotate through the transmission shaft, and the lifting horizontal sealing unit moves downward from the highest position to the lowest position. Under the action of the first cam member, the first driven translation member first maintains a fixed state, and the first horizontal sealing block and the second horizontal sealing block maintain a state of being merged with each other. While the packaging film moves downward synchronously with the lifting horizontal sealing unit, it also continues to maintain a state of being transversely heat-sealed by the first horizontal sealing block and the second horizontal sealing block.

[0023] B4, the cutting component cuts the transverse heat-sealed portion of the packaging film;

[0024] B5. The driving motor continues to synchronously drive the first cam member and the lifting driving member of the lifting driving assembly to rotate through the transmission shaft. The first cam member then drives the first driven translation member to move horizontally in a positive direction. The first driven translation member drives the transverse sealing driving member to rotate positively through the connecting rod mechanism. The transverse sealing driving member synchronously drives the first push-pull mechanism and the second push-pull mechanism. The first push-pull mechanism and the second push-pull mechanism drive the first transverse sealing block and the second transverse sealing block to separate from each other, thereby loosening the packaging film. The lifting and transverse sealing unit moves down to the lowest position, and the transmission shaft completes a 360° rotation. Thereafter, step B1 is repeated in a cycle.

[0025] The beneficial effect of the present invention is that the present invention can enable the transverse sealing component to move downward synchronously with the packaging film while transversely sealing the packaging film. The packaging film does not need to wait for the transverse sealing component to complete transverse sealing. The packaging film can continue to move downward while the transverse sealing component is transversely sealing it, thereby greatly improving the transverse sealing efficiency of the packaging machine, and further significantly improving the packaging efficiency of the entire packaging machine.

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Combined with Figure 1 To Attachment Figure 4 As shown, a high-speed transverse sealing device includes a driving unit 10 and a lifting transverse sealing unit 20. The driving unit 10 is used to drive the lifting transverse sealing unit 20 to perform lifting and film sealing movements. The lifting transverse sealing unit 20 includes a lifting main frame 21 and a transverse sealing component 22 for transversely sealing the packaging film. The transverse sealing component 22 is installed on the lifting main frame 21. The driving unit 10 includes a driving motor 11, a transmission shaft 12, a first cam member 13, and a lifting driving component 14. The first cam member 13 is fixedly connected to the transmission shaft 12. The lifting driving component 14 includes a lifting driving component 141 fixedly connected to the transmission shaft 12. The driving motor 11 synchronously drives the first cam member 13 and the lifting driving component 141 through the transmission shaft 12. The first cam member 13 drives the transverse sealing component 22 of the lifting transverse sealing unit 20 to perform film sealing movements. The lifting driving component 14 drives the lifting transverse sealing unit 20 to perform lifting movements. When in use, the driving motor 11 of the driving unit 10 synchronously drives the first cam member 13 and the lifting driving member 141 of the lifting driving assembly 14 through the transmission shaft 12, so that the transverse sealing assembly 22 can perform transverse sealing on the packaging film and also move downward synchronously with the packaging film. The packaging film does not need to wait for the transverse sealing assembly 22 to complete transverse sealing. The packaging film can continue to move downward while the transverse sealing assembly 22 performs transverse sealing on it, thereby greatly improving the transverse sealing efficiency of the packaging machine, and further significantly improving the packaging efficiency of the entire packaging machine.

[0035] Combined with Figure 1 and attached Figure 2As shown, the transverse sealing assembly 22 includes a first driven translation member 221, a connecting rod mechanism 222, a driven shaft 223, a transverse sealing driving member 224, a first push-pull mechanism 225, a second push-pull mechanism 226, a first translation seat 227, a second translation seat 228, and a first transverse sealing pressure block 2271 and a second transverse sealing pressure block 2281 fixedly mounted on the first translation seat 227 and the second translation seat 228, respectively. The first cam member 13 is connected to the first driven translation member 221, the first driven translation member 221 is movably connected to the input end of the connecting rod mechanism 222, the output end of the connecting rod mechanism 222 is fixedly connected to the driven shaft 223, the transverse sealing driving member 224 is fixedly arranged on the driven shaft 223, and the transverse sealing driving member 224 is hinged to the first push-pull rod 2251 of the first push-pull mechanism 225 and the second push-pull rod 2261 of the second push-pull mechanism 226, respectively. During operation, the first cam member 13 drives the first driven translation member 221 to translate. During the translation process, the first driven translation member 221 drives the connecting rod mechanism 222. The connecting rod mechanism 222 drives the driven shaft 223 to rotate. The transverse sealing driving member 224 rotates synchronously with the driven shaft 223. When the transverse sealing driving member 224 rotates, it will simultaneously drive the first push-pull mechanism 225 and the second push-pull mechanism 226. The first push-pull mechanism 225 and the second push-pull mechanism 226 respectively drive the first transverse sealing block 2271 and the second transverse sealing block 2281, thereby realizing transverse sealing.

[0036] Combined with Figure 1 and attached Figure 2 As shown, the first cam member 13 is a cylindrical cam, and the first driven translation member 221 is provided with a roller 2211 that moves along the groove 131 of the first cam member 13. The first cam member 13 drives the first driven translation member 221 to move horizontally back and forth through the roller 2211. When the first cam member 13 rotates, it drives the first driven translation member 221 to move horizontally, and the groove 131 of the first cam member 13 drives the first cam member 13 to move horizontally through the roller 2211.

[0037] Combined with Figure 1 To Attachment Figure 4As shown, the lifting drive assembly 14 is a cam mechanism or a crank connecting rod mechanism. Specifically, when the lifting drive assembly 14 is a cam mechanism, the lifting drive member 141 of the lifting drive assembly 14 is a cam, and when the lifting drive member 141 rotates, it will drive the lifting main frame 21 to perform vertical lifting movement, and the horizontal sealing assembly 22 installed at the lifting main frame 21 will also move up or down synchronously with the lifting main frame 21. When the lifting drive assembly 14 is a crank connecting rod mechanism, the lifting drive member 141 of the drive assembly is a crank, and a connecting rod is arranged between the lifting main frame 21 and the lifting drive member 141, and the two ends of the connecting rod are respectively hinged to the lifting drive member 141 and the lifting main frame 21. When the lifting drive member 141 rotates, it will drive the lifting main frame 21 to perform vertical lifting movement through the connecting rod, and the horizontal sealing assembly 22 installed at the lifting main frame 21 will also move up or down synchronously with the lifting main frame 21.

[0038] Combined with Figure 2 and attached Figure 3 As shown, the connecting rod mechanism 222 includes a first connecting rod 2221, a second connecting rod 2222, a third connecting rod 2223, and a pin 2224. The first connecting rod 2221 is rotatably arranged on the pin 2224. One end of the first connecting rod 2221 is movably connected to the first driven translation member 221. The two ends of the second connecting rod 2222 are respectively hinged to one end of the third connecting rod 2223 and the other end of the first connecting rod 2221. The other end of the third connecting rod 2223 is fixedly connected to the driven shaft 223. Figure 2 As shown, the first driven translation member 221 is provided with a vertical groove 2212, the lower end of the first connecting rod 2221 is provided with a rolling member 22211, the upper end of the first connecting rod 2221 is hinged with the second connecting rod 2222, the rolling member 22211 moves in the vertical groove 2212, and the first driven translation member 221 drives the rolling member 22211 to move vertically up and down in the vertical groove 2212 when translating. The first driven translation member 221 drives the first connecting rod 2221 to deflect through the rolling member 22211, and the first connecting rod 2221 The third connecting rod 2223 is driven by the second connecting rod 2222, and the third connecting rod 2223 deflects synchronously with the first connecting rod 2221. While deflecting, the third connecting rod 2223 drives the driven shaft 223 to rotate, and the transverse sealing driving member 224 rotates synchronously with the driven shaft 223. When the transverse sealing driving member 224 rotates, it drives the first push-pull mechanism 225 and the second push-pull mechanism 226 at the same time. The first push-pull mechanism 225 and the second push-pull mechanism 226 respectively drive the first transverse sealing block 2271 and the second transverse sealing block 2281, thereby realizing transverse sealing.

[0039] Combined with Figure 1 and attached Figure 2As shown, the first push-pull mechanism 225 includes a compression spring 2252, a first movable plate 2253, and a first connecting rod 2254. The two ends of the first push-pull rod 2251 are respectively hinged to the hinged seats of the transverse seal driving member 224 and the first movable plate 2253. The two ends of the first connecting rod 2254 are respectively fixedly connected to the first movable plate 2253 and the first translation seat 227. One end of the compression spring 2252 is fixedly arranged, and the other end of the compression spring 2252 is in conflict with the first movable plate 2253. Since the connection between the first push-pull rod 2251 and the transverse seal driving member 224 and the first movable plate 2253 is hinged, there is a large gap between the hinged shaft and the hole, which is prone to movement, resulting in low transmission accuracy. The compression spring 2255 can make the hinge between the first push-pull rod 2251 and the transverse seal driving member 224 and the first movable plate 2253 tighter, thereby improving the transmission accuracy.

[0040] Combined with Figure 1 and attached Figure 2 As shown, the second push-pull mechanism 226 includes a second connecting rod 2262, and both ends of the second push-pull rod 2261 are respectively hinged to the horizontal sealing drive member 224 and the hinged seat of one end of the second connecting rod 2262, and the other end of the second connecting rod 2262 is fixedly connected to the second translation seat 228. When the transverse sealing driving member 224 rotates, it will simultaneously drive the first push-pull rod 2251 of the first push-pull mechanism 225 and the second push-pull rod 2261 of the second push-pull mechanism 226. The first push-pull rod 2251 of the first push-pull mechanism 225 drives the first movable plate 2253, the first movable plate 2253 drives the first connecting rod 2254, the first connecting rod 2254 drives the first translation seat 227, and the first transverse sealing pressure block 2271 translates with the first translation seat 227; similarly, the second push-pull rod 2261 of the second push-pull mechanism 226 drives the second connecting rod 2262, the second connecting rod 2262 drives the second translation seat 228, and the second transverse sealing pressure block 2281 translates with the second translation seat 228.

[0041] Combined with Figure 1 As shown, the present invention also includes a cutting assembly 30 disposed at the first translation seat 227 or the second translation seat 228, and the cutting assembly 30 is used to cut the packaging film that has been heat-sealed. The cutting assembly 30 specifically includes a driving cylinder 31 and a cutter 32. The cutter 32 is specifically disposed in the knife groove of the first transverse sealing block 2271 or the second transverse sealing block 2281. The telescopic rod of the driving cylinder 31 is connected to the cutter 32, and the driving cylinder 31 drives the cutter 32 to cut the packaging film that has been heat-sealed or cut out an easy-tear line. When the cutter 32 cuts the packaging film that has been heat-sealed, the packaged product is a single independent product package. When the cutter 32 cuts out an easy-tear line on the packaging film that has been heat-sealed, the packaged product is a product connected package formed by connecting a plurality of product packages, and a single independent product package can be directly torn out along the easy-tear line from the product connected package.

[0043] A1. The driving motor 11 synchronously drives the first cam member 13 and the lifting driving member 141 of the lifting driving assembly 14 to rotate through the transmission shaft 12. The first cam member 13 drives the transverse sealing assembly 22, and the lifting driving member 141 drives the lifting transverse sealing unit 20 to move upward from the lowest position to the highest position.

[0044] At the same time, when the first cam member 13 rotates, it first drives the first driven translation member 221 to move horizontally in the positive direction. The first driven translation member 221 drives the transverse sealing driving member 224 to rotate positively through the connecting rod mechanism 222. The transverse sealing driving member 224 simultaneously drives the first push-pull mechanism 225 and the second push-pull mechanism 226. The first push-pull mechanism 225 and the second push-pull mechanism 226 drive the first transverse sealing pressing block 2271 and the second transverse sealing pressing block 2281 to separate from each other.

[0045] A2. When the first transverse sealing block 2271 and the second transverse sealing block 2281 are separated from each other to the maximum distance, the first cam member 13 continues to rotate and drives the first driven translation member 221 to move horizontally in the opposite direction. The first driven translation member 221 drives the transverse sealing driving member 224 to rotate in the opposite direction through the connecting rod mechanism 222. The transverse sealing driving member 224 drives the first transverse sealing block 2271 and the second transverse sealing block 2281 to merge with each other through the first push-pull mechanism 225 and the second push-pull mechanism 226, thereby clamping the packaging film. When the lifting transverse sealing unit 20 moves up to the highest position, the packaging film begins to be heat-sealed in the transverse direction.

[0046] A3, the driving motor 11 continues to synchronously drive the first cam member 13 and the lifting driving member 141 of the lifting driving assembly 14 to rotate through the transmission shaft 12, and the lifting and transverse sealing unit 20 moves downward from the highest position to the lowest position. Under the action of the first cam member 13, the first driven translation member 221 first maintains a fixed state, and the first transverse sealing block 2271 and the second transverse sealing block 2281 maintain a state of being merged with each other. While the packaging film moves downward synchronously with the lifting and transverse sealing unit 20, it also continues to maintain a state of being transversely heat-sealed by the first transverse sealing block 2271 and the second transverse sealing block 2281;

[0047] A4, the driving motor 11 continues to synchronously drive the first cam member 13 and the lifting drive member 141 of the lifting drive assembly 14 to rotate through the transmission shaft 12, and the first cam member 13 then drives the first driven translation member 221 to move horizontally in the positive direction, and the first driven translation member 221 drives the transverse sealing drive member 224 to rotate positively through the connecting rod mechanism 222, and the transverse sealing drive member 224 synchronously drives the first push-pull mechanism 225 and the second push-pull mechanism 226, and the first push-pull mechanism 225 and the second push-pull mechanism 226 drive the first transverse sealing block 2271 and the second transverse sealing block 2281 to separate from each other, thereby loosening the packaging film, and the lifting and transverse sealing unit 20 moves down to the lowest position, and the transmission shaft 12 completes a 360° rotation, and then repeats step A1 in a cycle.

[0048] Combined with Figure 1 To Attachment Figure 4 As shown, a working method of a high-speed transverse sealing device, based on the above-mentioned high-speed transverse sealing device and cutting assembly 30, includes the following steps:

[0049] B1. The driving motor 11 synchronously drives the first cam member 13 and the lifting driving member 141 of the lifting driving assembly 14 to rotate through the transmission shaft 12. The first cam member 13 drives the transverse sealing assembly 22, and the lifting driving member 141 drives the lifting transverse sealing unit 20 to move upward from the lowest position to the highest position.

[0050] At the same time, when the first cam member 13 rotates, it first drives the first driven translation member 221 to move horizontally in the positive direction. The first driven translation member 221 drives the transverse sealing driving member 224 to rotate positively through the connecting rod mechanism 222. The transverse sealing driving member 224 simultaneously drives the first push-pull mechanism 225 and the second push-pull mechanism 226. The first push-pull mechanism 225 and the second push-pull mechanism 226 drive the first transverse sealing pressing block 2271 and the second transverse sealing pressing block 2281 to separate from each other.

[0051] B2. When the first transverse sealing block 2271 and the second transverse sealing block 2281 are separated from each other to the maximum distance, the first cam member 13 continues to rotate and drives the first driven translation member 221 to move horizontally in the opposite direction. The first driven translation member 221 drives the transverse sealing driving member 224 to rotate in the opposite direction through the connecting rod mechanism 222. The transverse sealing driving member 224 drives the first transverse sealing block 2271 and the second transverse sealing block 2281 to merge with each other through the first push-pull mechanism 225 and the second push-pull mechanism 226, thereby clamping the packaging film. When the lifting transverse sealing unit 20 moves up to the highest position, the packaging film begins to be transversely heat-sealed.

[0052] B3, the driving motor 11 continues to synchronously drive the first cam member 13 and the lifting driving member 141 of the lifting driving assembly 14 to rotate through the transmission shaft 12, and the lifting and transverse sealing unit 20 moves downward from the highest position to the lowest position. Under the action of the first cam member 13, the first driven translation member 221 first maintains a fixed state, and the first transverse sealing block 2271 and the second transverse sealing block 2281 maintain a state of being merged with each other. While the packaging film moves downward synchronously with the lifting and transverse sealing unit 20, it also continues to maintain a state of being transversely heat-sealed by the first transverse sealing block 2271 and the second transverse sealing block 2281;
