Description

Technical Field

[0001] The invention belongs to the technical field of application of polymer polyethylene product processing equipment, and in particular relates to a continuous packaging edge sealing device used for polymer polyethylene product processing. Background Art

[0002] Polyethylene is an engineering plastic with impact resistance, wear resistance, good self-lubricating properties and excellent low-temperature performance. As the technology of high molecular weight polyethylene engineering plastic products matures, more and more projects have adopted this new type of thermoplastic engineering plastic.

[0003] At present, some small high molecular weight polyethylene products are usually packaged in plastic bags or plastic wrap after processing. After the packaging is sealed, it is convenient for the storage and transportation of high molecular weight polyethylene products. In the prior art, the packaging edge sealing equipment for high molecular weight polyethylene products still has deficiencies when used. The deficiencies are as follows:

[0004] 1. When the sealing head is pressed down to seal the edge, the mouth of the packaging bag is easily misaligned and wrinkled, resulting in loose edge sealing, thus affecting the edge sealing quality;

[0005] 2. When the existing edge sealing equipment is working, the edge sealing work and the conveying work of the packaging bag are driven and controlled separately by different driving devices, which leads to the loose coordination of the various mechanisms in the equipment, which is not conducive to improving the work efficiency;

[0006] 3. After the edge sealing of the packaging bag is completed, the staff is often required to manually cut off the excess material on the edge sealing, or set up an independent edge cutting device, which leads to increased equipment costs, increased labor intensity and operation difficulty, thus affecting processing efficiency.

DETAILED DESCRIPTION

[0034] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0035] like Figure 1-6 As shown, a continuous packaging edge sealing device for processing high molecular polyethylene products includes a base 1, a fixing frame 2, a conveyor belt 3 and a sealing head 4, wherein the fixing frame 2 is fixed on the base 1, the conveyor belt 3 is installed on the fixing frame 2, and the sealing head 4 is used to seal the edge of the packaging bag, and also includes:

[0036] The packaging seat 5 adopts a hollow structure. A hydraulic cylinder 501 for driving the packaging seat 5 to rise and fall is installed on the fixing frame 2. A fixing seat 502 is fixed inside the packaging seat 5.

[0037] There are two cantilever arms 6, which are respectively hinged on both sides of the fixed seat 502. A spring 601 is connected between the two cantilever arms 6. When the packaging seat 5 moves downward, the lower ends of the two cantilever arms 6 contact the conveyor belt 3 and deflect in the direction away from each other. A strip groove 503 is provided at the bottom of the packaging seat 5. The two cantilever arms 6 penetrate and slide in the strip groove 503. The spring 601 is used to ensure that the two cantilever arms 6 are in a trend of approaching each other, so that the lower ends of the cantilever arms 6 are in close contact with the surface of the conveyor belt 3;

[0038] There are two packaging plates 7, which are rotatably connected to the lower ends of the two cantilevers 6 respectively. The packaging head 4 is installed on the packaging plate 7. The packaging plate 7 is provided with a pressing assembly 8 and a trimming assembly 9;

[0039] During operation, the packaging seat 5 is driven downward by the hydraulic cylinder 501, and after the lower ends of the two cantilevers 6 contact the packaging bag on the conveyor belt 3, they swing away from each other, and the two packaging heads 4 can move from the middle of the packaging bag to both sides, so as to achieve rapid edge sealing of the packaging bag and improve work efficiency. Moreover, the two packaging heads 4 move away from each other, so as to tighten and straighten the edge sealing of the packaging bag, avoid wrinkles and misalignment of the packaging bag mouth, and improve the edge sealing quality.

[0040] The conveying assembly 10 includes a connecting rod 1001, a transmission rod 1002 and a ratchet 1003. The conveying belt 3 includes a roller shaft 301 for providing power. The roller shaft 301 is fixed to the ratchet 1003. The connecting rod 1001 is fixed to the packaging seat 5. The transmission rod 1002 is fixed to the connecting rod 1001. The transmission rod 1002 is provided with ratchets that match and mesh with the ratchet 1003. When the packaging seat 5 moves up, the ratchets can drive the ratchet 1003 to rotate, so that the conveying belt 3 drives the packaging bag to be transported forward by one station. When the packaging seat 5 moves down, the ratchets cannot drive the ratchet 1003 to rotate, and the conveying belt 3 does not move.

[0041] With the packaging seat 5 as the driving force, after each edge sealing work is completed, the packaging seat 5 moves up, and through the transmission rod 1002 and the ratchet 1003, the conveyor belt 3 intermittently conveys the packaging bag forward one station, thereby realizing continuous packaging edge sealing operation without the need to set up an additional power drive device, so that the edge sealing and conveying work of the packaging bag are linked and coordinated, effectively improving the processing efficiency;

[0042] The pressing assembly 8 includes a slot 801 formed at one end of the packaging plate 7, a rotating shaft 802 is rotatably connected in the slot 801, the rotating shaft 802 is connected to the side wall of the slot 801 through a spring 804, and a pressing wheel 803 is fixed on the rotating shaft 802 for pressing the edge of the package. During the edge sealing process, the packaging plate 7 drives the pressing wheel 803 to move synchronously, and the pressing wheel 803 can roll and press at the mouth of the packaging bag to further ensure the edge sealing quality.

[0043] The blowing assembly 11 includes an air pump 1101, an arc rod 1102, an air collecting box 1103, a connecting pipe 1104 and a nozzle 1105. The air pump 1101 is fixed to the inner wall of the packaging seat 5, the arc rod 1102 is fixed to the cantilever 6, and the arc rod 1102 is connected to the piston in the air pump 1101. The air pump 1101 is similar to a piston cylinder structure. The piston slides back and forth in the air pump 1101 to inflate. The air box 1103 is fixed to the inner bottom surface of the packaging seat 5, and the air pump 1101 is connected to the air collecting box 1103 through the connecting pipe 1104. The air pump 1101 adopts an arc structure, and the center of the arc rod 1102 and the arc structure of the air pump 1101 falls on the hinge axis of the cantilever 6 and the fixed seat 502. When the cantilever 6 deflects, the piston is pushed by the arc rod 1102 to slide in the air pump 1101 to inflate the air collecting box 1103;

[0044] The nozzle 1105 is fixed to the lower end of the packaging seat 5 and is connected to the gas collecting box 1103. A solenoid valve 13 is provided at the connection point between the nozzle 1105 and the gas collecting box 1103. A touch-pressure switch 14 is provided on one side of the conveyor belt 3. The solenoid valve 13 is electrically connected to the power supply through the touch-pressure switch 14. When the edge pressing wheel 803 rolls onto the touch-pressure switch 14, the solenoid valve 13 is energized and opened.

[0045] During operation, the swing of the cantilever 6 is used as the driving force to drive the arc rod 1102 to push the piston to slide in the air pump 1101 and inflate the air collecting box 1103. When the two pressing wheels 803 move away from each other to the two sides of the conveyor belt 3, that is, after the edge sealing and trimming work is completed, the pressing wheels 803 roll onto the touch pressure switch 14, so that the solenoid valve 13 is energized and turned on. The air in the air collecting box 1103 is discharged by the nozzle 1105, and automatically blows air to the surface of the conveyor belt 3 to blow away the cut excess material to avoid affecting subsequent processing operations.

[0046] The trimming assembly 9 includes a mounting cylinder 901 disposed on the packaging plate 7, the mounting cylinder 901 is rotatably connected to the side wall of the packaging plate 7 through a connecting shaft 902, a pressing block 903 is slidably fitted in the mounting cylinder 901, the pressing block 903 is connected to the inner wall of the mounting cylinder 901 through a pressing spring 906, a knife holder 904 is fixed on the pressing block 903, a cutting knife 905 is installed on the knife holder 904, the cutting knife 905 is used to cut off the excess material at the edge of the packaging, and the setting of the pressing spring 906 is used to press the cutting knife 905 against the packaging bag on the surface of the conveyor belt 3 to ensure its cutting effect;

[0047] The packaging plate 7 is provided with a flip assembly 12, which is used to control the flipping adjustment of the installation cylinder 901. The flip assembly 12 includes a driving gear 1201 and a driven gear 1202. The driving gear 1201 is fixed on the rotating shaft 802, and the driven gear 1202 is fixed on the connecting shaft 902. The driving gear 1201 and the driven gear 1202 are meshed with each other. When the edge pressing wheel 803 rolls on the surface of the conveyor belt 3, the installation cylinder 901 can be driven to rotate synchronously through the driving gear 1201 and the driven gear 1202. By setting a spring 804, when the edge pressing wheel 803 rotates on the conveyor belt 3, the spring 804 is twisted and stored. When the installation cylinder 901 flips 180°, the spring 804 reaches the twisting limit, and then the edge pressing wheel 803 no longer rotates at this time. When the edge pressing wheel 803 slides on the conveyor belt, the packaging bag mouth can also be pressed.

[0048] When the two sealing heads 4 move away from each other to perform edge sealing, the flipping assembly 12 can automatically flip the cutting knife 905 180°. The cutting knife 905 is located at the residual material on the edge of the packaging bag after edge sealing. As the cantilever 6 swings, the residual material is automatically cut off. There is no need to set up an independent trimming device, which reduces equipment costs and allows edge sealing and trimming to be carried out continuously, thereby improving work efficiency. After the edge sealing is completed, the two cantilevers 6 swing in opposite directions and approach each other. At this time, the pressing wheel 803 rotates in the opposite direction, driving the cutting knife 905 to flip 180° in the opposite direction and reset. At this time, the cutting knife 905 rotates away from the conveyor belt 3 to prevent the cutting knife 905 from damaging the packaging bag when the conveyor belt 3 is transporting the packaging bag.

[0049] The working principle of the present invention is as follows:

[0050] Arrange the packaging bags to be sealed on the conveyor belt 3, start the hydraulic cylinder 501 to drive the packaging seat 5 to move downward, and after the edge pressing wheels at the lower ends of the two cantilevers 6 contact the packaging bags on the conveyor belt 3, the two cantilevers 6 swing away from each other, and the two sealing heads 4 can move from the middle of the packaging bag to both sides to achieve rapid edge sealing of the packaging bag, improve work efficiency, and the two sealing heads 4 move away from each other, which can tighten and straighten the edge sealing of the packaging bag to avoid wrinkles and misalignment of the packaging bag mouth, and improve the edge sealing quality. The packaging plate 7 drives the edge pressing wheel 803 to move synchronously, and the edge pressing wheel 803 can roll and press at the packaging bag mouth to further ensure the edge sealing quality;

[0051] When the two packaging heads 4 move away from each other to perform edge sealing, since the edge pressing wheel 803 rolls on the conveyor belt 3, the driving gear 1201 and the driven gear 1202 can drive the installation cylinder 901 to rotate 180° synchronously. At this time, the cutting knife 905 is located at the residual material on the edge of the packaging bag after edge sealing. With the swing of the cantilever 6, the residual material is automatically cut off. There is no need to set up an independent edge trimming device, which reduces the equipment cost, enables the edge sealing and edge trimming work to be carried out continuously, and improves the work efficiency. After the edge sealing is completed, the hydraulic cylinder 501 drives the packaging seat 5 to move up and reset, and the two cantilevers 6 swing in the opposite direction and approach each other. At this time, the edge pressing wheel 803 rotates in the opposite direction, driving the cutting knife 905 to flip 180° in the opposite direction and reset. At this time, the cutting knife 905 rotates away from the conveyor belt 3 to prevent the cutting knife 905 from damaging the packaging bag when the conveyor belt 3 transports the packaging bag.

[0052] During the upward movement of the packaging seat 5, the transmission rod 1002 is driven upward by the connecting rod 1001. In this direction, the ratchet can drive the ratchet wheel 1003 to rotate, so that the conveyor belt 3 intermittently transports the packaging bag forward one station, and moves the next packaging bag to be edge-sealed to the bottom of the packaging head 4. The packaging seat 5 can be driven downward again by the hydraulic cylinder 501 to perform the packaging work, and this reciprocating process is used to realize continuous packaging and edge-sealing operations. There is no need to set up an additional power drive device, so that the edge sealing and conveying work of the packaging bag are linked and coordinated, effectively improving the processing efficiency.
