Description

Technical Field

[0001] This application relates to the field of equipment for producing bagged products, and more particularly to packaging equipment for producing bagged products. Background Technology

[0002] While filling standard-sized products, daily chemical product production lines also produce small-sized sample bags as free gifts for consumers to use, helping them find products suitable for their needs. Even these sample bags must have production dates, expiration dates, and other product information printed on their surface according to relevant national regulations. Currently, packaging equipment for bagged products is equipped with inkjet printers at the end. After sealing, the bagged products pass through the inkjet printer, which prints relevant production information on the bag surface according to the production date preset by the staff. Because the packaging material for bagged products is plastic, friction occurs between the bags during transportation, causing the printed production date on the bag surface to fade. This results in unclear production dates and can easily lead to consumer complaints. Utility Model Content

[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0033] refer to Figures 1 to 10 A preferred embodiment of the packaging equipment for producing bagged products according to this application will be described in detail below.

[0034] refer to Figure 2 , Figure 5 and Figure 6 The packaging equipment for producing bagged products includes a machine body 10 and a roller assembly 20. The machine body 10 includes a main body 11 and a drive mechanism 12, which is mounted on the main body 11. The roller assembly 20 includes at least one feed roller 21 and at least one pair of take-up rollers 22. The feed roller 21 is mounted on the main body 11, and the packaging material roll is sleeved on the feed roller 21. Each pair of two take-up rollers 22 are mounted on the main body 11 at intervals with parallel axial orientation, and the take-up rollers 22 are connected to the drive mechanism 12, which drives the two take-up rollers 22 to rotate in opposite directions. The packaging material roll unwound from the feed roller 21 passes between each pair of two take-up rollers 22, and the two take-up rollers 22 in each pair transmit the packaging material roll through friction.

[0035] As an example, the drive mechanism 12 is implemented to include a motor.

[0036] In one embodiment, the roller assembly 20 includes two axially parallel unloading rollers 21. Each of the two unloading rollers 21 is loaded with two rolls of packaging material, one roll bearing a front label of the bagged product and the other roll bearing a back label of the bagged product. The two rolls of packaging material are unwound synchronously with the labeled sides facing away from each other.

[0037] In another embodiment, the roller group 20 includes a feeding roller 21, and a roll of packaging material is sleeved on the feeding roller 21. The two ends of one side of the packaging material strip along the width are respectively printed with the front and back markings of the bagged product. That is, the front and back markings of the bagged product are printed on the same side of the same packaging material roll. In this way, the synchronization rate of the front and back markings can be improved, and the number of feeding rollers 21 can be reduced, thereby reducing the cost of the packaging equipment used to produce bagged products.

[0038] refer to Figure 2 and Figure 3 Furthermore, the packaging equipment for producing bagged products also includes a cutting unit 30.

[0039] The cutting unit 30 includes a slitting blade 31 and a connecting seat 32. The connecting seat 32 is mounted on the main body 11 of the equipment, and the slitting blade 31 is mounted on the connecting seat 32. The slitting blade 31 is located on the path of the receiving roller 22 that conveys the packaging material strip, and the blade of the slitting blade 31 faces the junction of the front and back markings, so that the packaging material strip is cut into two packaging material strips with front and back markings respectively printed on them during the unwinding process.

[0040] Preferably, the connecting seat 32 includes a movable part 321 and a fixed part 322. The fixed part 322 is installed on the main body 11 of the equipment. The movable part 321 can move along the width direction of the packaging strip. The slitting blade 31 is installed on the movable part 321. In this way, the movable part 321 can drive the slitting blade 31 to move along the width direction of the packaging strip, thereby adjusting the position of the slitting blade 31 so that the slitting blade 31 can cut packaging strips of different sizes.

[0041] Preferably, the cutting unit 30 further includes a fixing member 33, which is installed between the movable part 321 and the fixed part 322 to fix the movable part 321.

[0042] In one embodiment, the fastener 33 is implemented as a bolt, the fixing portion 322 forms an insertion channel and a threaded hole extending radially along the insertion channel, and the movable portion 321 is inserted into the insertion channel formed by the fixing portion 322. The fastener 33 is threaded into the threaded hole and abuts against the outer wall of the movable portion 321.

[0043] In another embodiment, the fixing member 33 is implemented as a lockable cylinder, the cylinder body is mounted on the fixing part 322, the piston rod is connected to the movable part 321, the movable part 321 is moved by the extension and retraction of the cylinder, and the movable part 321 is locked and fixed by the cylinder.

[0044] refer to Figure 5 Furthermore, the roller group 20 also includes two opposing first directional rollers 23 and two opposing second directional rollers 24. The two first directional rollers 23 are mounted on the equipment body 11, and their axes intersect. The two second directional rollers 24 are mounted on the equipment body 11, and their axes are parallel to the axial direction of the receiving roller 22. The two strips of packaging material obtained from the slitting process sequentially pass around the two first directional rollers 23 and the two second directional rollers 24 before passing between at least one pair of receiving rollers 22. The first directional rollers 23 and the second directional rollers 24 are configured to adjust the two strips of packaging material obtained from the slitting process so that the sides printed with the front and back markings are facing opposite directions when conveyed by the receiving roller 22.

[0045] In one embodiment, the axis of each of the first directional rollers 23 forms an obtuse angle with the uncut packaging strip near the slitting blade 31. The uncut packaging strip is conveyed by the take-up roller 22 with the side with the front and back markings facing down. The two cut packaging strips pass over the two first directional rollers 23 from top to bottom on their adjacent sides, so that the unmarked side of the cut packaging strips faces down and they are conveyed in opposite directions. Then they pass over the two second directional rollers 24 and pass between at least one pair of take-up rollers 22, so that the unmarked sides of the two packaging strips face each other and are attached.

[0046] refer to Figure 5 and Figure 7 Preferably, the device body 10 further includes two pairs of movable members 13, which are slidably mounted on the device body 11. Each end of a second directional roller 24 is respectively mounted to one pair of movable members 13, and the pair of movable members 13 can move closer to or further away from the other pair of movable members 13, such that one second directional roller 24 can move closer to or further away from the other second directional roller 24. By adjusting the position of the second directional roller 24, the distance between the second directional roller 24 and the receiving roller 22 on the same side is adjusted to keep the slit packaging strip taut.

[0047] Preferably, the main body 11 of the device forms a sliding groove 1101, which extends along the distribution direction of the two second directional rollers 24. The moving member 13 is slidably mounted on the sliding groove 1101.

[0048] Furthermore, the device body 10 also includes an adjusting member 14. The adjusting member 14 is installed on the device body 11, and the moving member 13 is connected to the adjusting member 14, the adjusting member 14 being used to drive the moving member 13 to move.

[0049] As an example, the adjusting member 14 has an external thread formed on at least a portion of its outer peripheral wall, and the adjusting member 14 is rotatably connected to the moving member 13. The device body 11 has a threaded hole communicating with the sliding groove 1101, and the adjusting member 14 is threaded into the threaded hole. When the adjusting member 14 rotates, the moving member 13 moves closer to or further away from another pair of moving members 13, defined by the sliding groove 1101.

[0050] It is worth mentioning that the portion of the main body 11 of the device that forms the sliding groove 1101 is provided with a scale, and the scale extends along the extension direction of the sliding groove 1101, so that the operator can observe and grasp the moving distance of the moving part 13.

[0051] refer to Figure 2 Preferably, the roller group 20 further includes multiple conveyor rollers 25, which are installed at intervals on the main body 11 of the equipment, and the conveyor rollers 25 are parallel to the axial direction of the feeding roller 21. The conveyor rollers 25 are located between the feeding roller 21 and the slitting blade 31 and are used to convey uncut packaging material strips.

[0052] refer to Figure 1 and Figure 5 Furthermore, the packaging equipment for producing bagged products also includes a sealing unit 40, which is located between the second directional roller 24 and at least one pair of receiving rollers 22, for forming multiple independent sealed bags capable of containing materials between the two packaging material belts.

[0053] The packaging unit 40 includes a heat-sealing assembly 41, a first driving mechanism 42, and a pressure-applying component 43. Two packaging strips pass between the heat-sealing assembly 41 and the pressure-applying component 43 with their unmarked sides facing each other and in contact. The first driving mechanism 42 is mounted on the device body 11. The heat-sealing assembly 41 includes a first mounting portion 411 and a heat-sealing component 412. The heat-sealing component 412 is mounted on the side wall of the first mounting portion 411 facing the pressure-applying component 43, and is configured to heat the packaging strips. The pressure-applying component 43 is driven to the first driving mechanism 42, which drives the pressure-applying component 43 toward or away from the first mounting portion 411. The heat-sealing assembly 41 and the pressure-applying component 43 approach each other twice, so that the heat-sealing component 412 is heated to form multiple sealed bags.

[0054] refer to Figure 1 Furthermore, the packaging equipment for producing bagged products also includes at least one filling mechanism 50.

[0055] The device body 10 includes a support base 15. The filling mechanism 50 includes a filling pipe 51 and a hopper 52. The hopper 52 forms a material receiving space 5201, in which material is received. The filling pipe 51 is installed on the support base 15, and a discharge port is formed at the bottom of the filling pipe 51. The filling pipe 51 is connected to the hopper 52, and the material in the material receiving space 5201 is discharged from the discharge port through the filling pipe 51. One end of the filling pipe 51 forming the discharge port extends from the top of the bag body into the bag from top to bottom to fill the bag with material.

[0056] refer to Figure 5 Specifically, after the first driving mechanism 42 drives the pressure applying member 43 closer to the first mounting part 411, the heat sealing member 412 heats the packaging material strip to heat seal the two sides and bottom edge of the bag body. Then, the material in the material receiving space 5201 is injected into the bag through the filling tube 51 from the discharge port. Afterwards, the first driving mechanism 42 drives the pressure applying member 43 away from the first mounting part 411, and the receiving roller 22 continues to convey the packaging material strip, so that the bag body after filling is separated from the filling tube 51. Then, the first driving mechanism 42 drives the pressure applying member 43 closer to the first mounting part 411 again, so that the heat sealing member 412 heat seals the top edge of the bag body to form a sealed bag body.

[0057] It is worth mentioning that the heat-sealing components 41 together form a receiving space 4101, which corresponds to the middle position of the bag body to avoid squeezing the bag body and prevent material from spilling out.

[0058] As an example, the first drive mechanism 42 is implemented to include a cylinder.

[0059] It is worth mentioning that the first mounting part 411 can be pivotally connected to the main body 11 of the device in a lockable manner. In this way, by opening and unlocking the first mounting part 411, the packaging material strip between the first mounting part 411 and the pressure member 43 can be exposed, so that the staff can adjust the packaging material strip.

[0060] refer to Figure 5 , Figures 8 to 10 Furthermore, the packaging equipment for producing bagged products also includes a production information printing unit 60. The production information printing unit 60 is adjacent to the sealing unit 40 and is used to print production information on the edge of the bag.

[0061] The production information printing unit 60 includes a second mounting member 61, a second driving mechanism 62, a printing component 63, and a third mounting member 64. The second driving mechanism 62 is mounted on the equipment body 11. The second mounting member 61 and the third mounting member 64 are arranged opposite to each other, and the second mounting member 61 is connected to the second driving mechanism 62. The second driving mechanism 62 drives the second mounting member 61 to move closer to or away from the third mounting member 64. The packaging material tape, after being sealed by the sealing unit 40, passes sequentially between the second mounting member 61 and the third mounting member 64 and between at least one pair of receiving rollers 22. The printing component 63 is mounted on the side wall of the second mounting member 61 facing the third mounting member 64. The end of the printing component 63 facing the third mounting member 64 is engraved with numbers, such as production date, expiration date, etc., so that when the second mounting member 61 moves closer to the third mounting member 64, the printing component 63 applies pressure to the edge of the bag to print new production information.

[0062] Preferably, the printing assembly 63 includes a loading body 631 and a plurality of closely connected letter carriers 632. One end of each letter carrier 632 is engraved with numbers. The loading body 631 forms a through-slot 63101, a disassembly port 63102 communicating with the through-slot 63101, and a window 63103 communicating with the through-slot 63101. The loading body 631 is mounted on a side wall of the third mounting member 64 facing the second mounting member 61. The letter carriers 632 move into and out of the through-slot 63101 through the disassembly port 63102, and when the letter carriers 632 are loaded into the through-slot 63101 through the disassembly port 63102, the end of the letter carrier 632 with the engraved numbers extends from the window 63103 towards the edge of the bag body to form production information on the edge of the bag body.

[0063] Understandably, the staff removes the letter carrier 632 from the through slot 63101 through the disassembly port 63102 and installs the letter carrier 632 with the corresponding number into the through slot 63101 so that the letter carrier 632 prints new production information on the bag.

[0064] Preferably, the loading body 631 is detachably mounted to the third mounting member 64 by screws, and the disassembly port 63102 abuts against the third mounting member 64, while the window 63103 is opposite to the second mounting member 61. When the loading body 631 and the third mounting member 64 are assembled, the disassembly port 63102 is hidden; when the loading body 631 and the third mounting member 64 are disassembled, the disassembly port 63102 is opened, and the worker replaces the corresponding letter carrier 632 through the disassembly port 63102 so that the letter carrier 632 has the day's production information printed on the edge of the bag.

[0065] Furthermore, the loading body 631 is configured to heat the edge of the bag, so that the loading body 631 heats the letter 632 through heat conduction, and the printing components 63 jointly heat the edge of the bag, ensuring the clarity of the printed production information.

[0066] Preferably, the third mounting member 64 is pivotally and lockably connected to the device body 11. In this way, by opening the third mounting member 64, the packaging material strip between the third mounting member 64 and the second mounting member 61 can be exposed, so that the staff can adjust the packaging material strip. At the same time, the third mounting member 64 drives the printing component 63 to rotate away from the second mounting member 61, so as to provide the staff with more operating space and facilitate the replacement of the letter carrier 632.

[0067] refer to Figure 5 Furthermore, the packaging equipment for producing bagged products also includes a cutting unit 70, which is adjacent to the production information printing unit 60 and is used to form cutting lines around the bag body to produce individual bagged products.

[0068] It is worth mentioning that the roller group 20 also includes a waste collection roller 26. The waste collection roller 26 is rotatably connected to the drive mechanism 12, which drives the waste collection roller 26 to rotate, so that waste is wound up in the waste collection roller 26, and at the same time, the waste collection roller 26 can pull the packaging material belt for conveying.

[0069] Specifically, the cutting unit 70 includes an abutment plate 71, a cutting assembly 72, and a third driving mechanism 73. The cutting assembly 72 includes an assembly 721 and a cutting blade 722. The assembly 721 and the abutment plate 71 are arranged opposite to each other. The packaging material strip after the production information is printed by the production information printing unit 60 passes sequentially between the assembly 721 and the abutment plate 71.

[0070] The cutting blade 722 is mounted on the side of the assembly 721 facing the abutment plate 71. The assembly 721 is connected to the third drive mechanism 73, which drives the cutting assembly 72 to move closer to or away from the abutment plate 71. Specifically, when the third drive mechanism 73 drives the cutting assembly 72 to move closer to the abutment plate 71, the cutting blade 722 forms a cutting line around the perimeter of the bag body for subsequent separation.

[0071] As an example, the third drive mechanism 73 is implemented as a cylinder.

[0072] refer to Figure 1 and Figure 5 Furthermore, the packaging equipment for producing bagged products also includes a feeding unit 80, which is located between the cutting unit 70 and the waste collection roller 26, and is used to peel the bagged products off the packaging material strip.

[0073] Specifically, the unloading unit 80 includes a translation drive 81 and an unloading component 82. The translation drive 81 is mounted on the main body 11 of the equipment, and the unloading component 82 is connected to the translation drive 81. The translation drive 81 drives the unloading component 82 to move closer to and away from the bagged product, thereby causing the bagged product to be peeled off the packaging tape along the cutting line via the unloading component 82.

[0074] In a preferred embodiment, the feeding component 82 is implemented as a suction cup, which is connected to a negative pressure device via a pipeline. The negative pressure device extracts air from the side of the suction cup facing the bag body via the pipeline, so that after the translation drive 81 drives the feeding component 82 to approach the bagged product, the suction cup picks up the bagged product, and then the translation drive 81 drives the feeding component 82 to move away from the packaging strip, ensuring that the bagged product is peeled off from the packaging strip.

[0075] Preferably, the feeding unit 80 further includes a blocking member 83, which is installed on the main body 11 of the equipment and located on the moving path of the waste material toward the direction of peeling off the packaging material strip of the bagged product, so as to facilitate the peeling off of the bagged product.

[0076] refer to Figure 2 and Figure 4Furthermore, the packaging equipment for producing bagged products also includes a material strip sensor 90 and a controller.
