Description

Technical Field

[0001] The invention relates to the technical field of packaging machines, in particular to an ultrasonic reciprocating packaging machine. Background Art

[0002] Existing packaging machines all use electric heating to perform longitudinal and transverse sealing.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 6 The embodiment of the present invention provides an ultrasonic reciprocating packaging machine, comprising a frame 1 and an unwinding mechanism 2 for unwinding an outer packaging coil arranged on the frame 1, a conveying roller 3 for conveying the outer packaging, a former 4 for forming the outer packaging, a feeding conveying mechanism 5 and a discharging conveying mechanism 6 for conveying the outer packaging and the material placed therein, an ultrasonic longitudinal sealer 7 for longitudinally sealing the outer packaging, and an ultrasonic end sealer 8 for sealing the two ends of the outer packaging, wherein the ultrasonic longitudinal sealer 7 is arranged above the feeding conveying mechanism 5, and the ultrasonic end sealer 8 is arranged across the gap between the feeding conveying mechanism 5 and the discharging conveying mechanism 6; the feeding conveying mechanism 5 and the discharging conveying mechanism 6 are located on the same horizontal plane, and the feeding conveying mechanism 5 and the discharging conveying mechanism 6 are respectively provided with an adjusting mechanism 9 for dynamically adjusting the gap between the end of the feeding conveying mechanism 5 and the head end of the discharging conveying mechanism 6.

[0024] Specifically, the outer packaging coil is unwound by the unwinding mechanism 2, and then conveyed to the former 4 by the conveying roller 3 to be formed into a packaging bag with an enclosed space. The material to be packaged is conveyed into the inner enclosed space of the packaging bag, and then conveyed by the feeding conveying mechanism 5. During the conveying process, the ultrasonic longitudinal sealer 7 longitudinally seals the packaging material, and then continues to convey. When the front and rear ends of the adjacent materials wrapped by the packaging material enter the gap between the feeding conveying mechanism 5 and the discharging conveying mechanism 6, the ultrasonic end sealer 8 welds the packaging material between the adjacent materials, i.e., end seals, and cuts them to separate the front and rear packaged materials into Finished product, the present invention uses ultrasonic sealing operation to avoid the problem of uneven heating of electric heating seal affecting the sealing quality. At the same time, the feed conveying mechanism 5 and the discharging conveying mechanism 6 are respectively provided with an adjusting mechanism 9 for dynamically adjusting the gap between the end of the feed conveying mechanism 5 and the head end of the discharging conveying mechanism 6. The gap between the end of the feed conveying mechanism 5 and the head end of the discharging conveying mechanism 6 can be dynamically adjusted through the adjusting mechanism 9, so that the gap between the end of the feed conveying mechanism 5 and the head end of the discharging conveying mechanism 6 is most suitable for operation when the packaging material is in the two states of end sealing and conveying, thereby ensuring the quality of the packaged product.

[0025] Furthermore, the feed conveying mechanism 5 and the discharge conveying mechanism 6 each include a pair of side plates 501, and fixed guide rollers 502, driving rollers 503, intermediate guide rollers 504, floating rollers arranged between the pair of side plates 501 and spaced apart along the conveying direction, and a conveying belt 505 wound around the fixed guide rollers 502, the driving rollers 503, the intermediate guide rollers 504 and the floating rollers in sequence, the driving rollers 503 being externally connected to a power mechanism, and the conveying belt 505 is driven by the driving rollers 503 along the fixed guide rollers. The roller 502, the middle guide roller 504 and the floating roller are used to transport the articles thereon. The adjusting mechanism 9 includes a first linear rail 901, a first slider 902, a sliding plate 903 and a grooved cam 905. The first linear rail 901 is arranged on a pair of side plates 501. The sliding plates 903 are slidably connected to the first linear rail 901 through the first sliders 902. The two ends of the floating roller are respectively connected to the sliding plates 903. The grooved cam 905 can move in the vertical direction. A sliding groove 906 is provided on the wheel 905. The sliding grooves 906 corresponding to the feed conveying mechanism 5 and the discharging conveying mechanism 6 are first brought together and then separated in the vertical downward direction. A roller 904 that can slide along the sliding groove 906 is provided on one side of the sliding plate 903. Since the sliding grooves 906 corresponding to the feed conveying mechanism 5 and the discharging conveying mechanism 6 are first brought together and then separated in the vertical downward direction, when the grooved cam 905 moves downward in the vertical direction, it drives the sliding plates 903 of the feed conveying mechanism 5 and the discharging conveying mechanism 6 to move closer to each other, so that the distance between the two is reduced, thereby facilitating transportation; when the grooved cam 905 moves upward in the vertical direction, it drives the sliding plates 903 of the feed conveying mechanism 5 and the discharging conveying mechanism 6 to move away from each other, so that the distance between the two is increased. At this time, a larger operating space can be provided for end sealing and slitting, which is convenient for efficient end sealing and slitting operations. It has a simple structure and can realize dynamic adjustment to meet different operating tasks.

[0026] Preferably, the floating rollers include a first floating roller 506 and a second floating roller 507. The first floating roller 506 is close to the driving roller 503 and is arranged at the lower part of the sliding plate 903, and the second floating roller 507 is away from the first floating roller 506 and is arranged at the upper part of the sliding plate 903. When the sliding groove 906 of the groove cam 905 drives the sliding plate 903 to slide along the first linear rail 901 through the roller 904, the distance between the first floating roller 506 and the fixed guide roller 502 of the feed conveying mechanism 5 and the discharge conveying mechanism 6 and the distance between the second floating roller 507 and the middle guide roller 504 increase or decrease in opposite directions synchronously, thereby ensuring the tension of the conveyor belt 505, that is, when the distance between the first floating roller 506 and the fixed guide roller 502 increases, the distance between the second floating roller 507 and the middle guide roller 504 decreases synchronously.

[0027] The ultrasonic longitudinal sealer 7 in this embodiment includes a front guide wheel 701, an ultrasonic welding wheel 702, a pressure wheel 704 and a rear guide wheel 703. The front guide wheel 701 and the rear guide wheel 703 are configured in pairs and arranged at intervals along the conveying direction. The ultrasonic welding wheel 702 cooperates with the pressure wheel 704 and is located between the front guide wheel 701 and the rear guide wheel 703. The front guide wheel 701 and the rear guide wheel 703 respectively roll and convey and position the packaging materials in front of and behind the ultrasonic welding wheel 702 to ensure that the ultrasonic welding wheel 702 can smoothly and stably cooperate with the pressure wheel 704 to longitudinally seal the packaging materials passing through them.

[0028] The ultrasonic end sealer 8 in this embodiment includes a pair of wall panels 801 and an ultrasonic die head 802 arranged between the pair of wall panels 801, a second linear rail 803, a lower die base 804, a lower die 805, a cutter assembly 806, and a driving mechanism 807. A grooved cam 905 is arranged on both sides of the lower die base 804, so that the movement of the sliding plate 903 is consistent with the sealing and slitting movements, that is, when the lower die base 804 and the ultrasonic die head 802 are close to each other to perform transverse welding and slitting on the packaging material, the two sliding plates 903 of the feeding conveying mechanism 5 and the discharging conveying mechanism 6 are away from each other. When the lower die base 804 and the ultrasonic die head 802 are away from each other, the two sliding plates 903 of the feeding conveying mechanism 5 and the discharging conveying mechanism 6 are close to each other to prevent the head of the packaging material containing the material from falling off. The upper end of the second linear rail 803 is slidably equipped with a second sliding plate. Block 813, the second slider 813 is connected to the wall panel 801 through the connecting seat 812, the lower end of the second linear rail 803 is connected to the lower mold seat 804, the ultrasonic die head 802 is slidably connected to the second linear rail 803 through the sliding seat 808, the lower mold 805 and the cutter assembly 806 are both arranged on the lower mold seat 804, and the driving mechanism 807 drives the lower mold seat 804 and the ultrasonic die head 802 to move closer to or away from each other. Specifically, the driving mechanism 807 drives the lower mold seat 804 to move upward and drive the second linear rail 803 upward, and at the same time the sliding seat 808 moves downward along the second linear rail 803, so that the lower mold 805 and the cutter assembly 806 are driven upward and the ultrasonic die head 802 is driven downward and close to the lower mold 805 to perform transverse welding and sealing on the packaging material. After the welding and sealing is completed, it is cut from the middle of the weld by the cutter assembly 806 to form a separate finished product.Furthermore, the driving mechanism 807 includes a power source 8071, a first rotating shaft 8072, a first rotating disk 8073, a second rotating shaft 8074 and a second rotating disk 8075, wherein the first rotating shaft 8072 and the second rotating shaft 8074 are arranged up and down, the power source 8071 is connected to the first rotating shaft 8072 and the second rotating shaft 8074 through a gear pair 8076, the first rotating disk 8073 is connected to the first rotating shaft 8072, a first notch 8077 is provided on the first rotating disk 8073, the sliding seat 808 is connected to the first rotating wheel 809 through a first connecting shaft 814, the first rotating wheel 809 cooperates with the first notch 8077, the second rotating disk 8075 is connected to the second rotating shaft 8074, the second rotating disk 8075 is provided with a second notch 8078, the lower mold base 804 is connected to the second rotating wheel 810 through a second connecting shaft 815, the second rotating wheel 810 cooperates with the second notch 8078 The power source 8071 drives the first rotating shaft 8072 and the second rotating shaft 8074 to rotate synchronously through the gear pair 8076, and then drives the first turntable 8073 and the second turntable 8075 to rotate synchronously. The sliding seat 808 cooperates with the first slot 8077 through the first rotating wheel 809 so that the sliding seat 808 follows the movement of the first turntable 8073 to rise and fall along the second linear rail 803. Similarly, the lower mold base 804 cooperates with the second slot 8078 of the second turntable 8075 through the second rotating wheel 810 so that the lower mold base 804 follows the movement of the second turntable 8075 and rises and falls as a whole. In this embodiment, a power source 8071 is used to synchronously drive the sliding seat 808 and the lower mold base 804 to move toward or away from each other, so as to realize the ultrasonic die head 802 and the lower mold 805 to approach each other for sealing or move away from each other. It has a simple structure, convenient control, and a synchronous and stable operation process.

[0029] The cutter assembly 806 in this embodiment adopts the existing structure, which includes a cylinder 8061 and a cutter 8062. The cutter 8062 is arranged in the lower mold 805, and the output end of the cylinder 8061 is connected to the cutter 8062.

[0030] A third linear rail 811 is also horizontally provided at the upper end of the wall panel 801, and a connecting seat 812 is slidably connected to the third linear rail 811.
