Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, and in particular to a potassium monopersulfate complex filling device and method. Background Art

[0002] Potassium monopersulfate complex is an inorganic acidic oxidant, a free-flowing white granular powder that is easily soluble in water. It is relatively stable in the solid state, decomposes slowly, and does not produce harmful substances. The stability of potassium monopersulfate complex under acidic conditions is much higher than that under neutral conditions, and it will decompose rapidly under alkaline conditions. It undergoes a chain reaction in water, continuously producing new ecological oxygen, hypochlorous acid, free hydroxyl, hydrogen peroxide and other active ingredients, thus becoming a highly efficient oxidative disinfectant with a wide range of microbial killing effects, including bacteria, spores, viruses, fungi, etc.

[0003] The Chinese patent document with the announcement number CN117735005B discloses a material collection and packaging machine and a packaging method of alumina powder for electronic glass production, including a frame, a collection hopper and a reeling mechanism are fixedly installed on the top of the frame, a drop tube located below the collection hopper is fixedly installed on one side of the frame, a limited positioning shaping mechanism is arranged on the outer ring of the drop tube, an edge sealing mechanism located on the inner side below the limited positioning shaping mechanism and a sealing mechanism located below the drop tube are also fixedly installed on one side of the frame, and a sealing mechanism is arranged at the discharge port of the drop tube to press the packaging bag tightly. The sealing protection mechanism on the discharge pipe is used to prevent the powder from scattering into the gap between the cylindrical packaging paper and the drop pipe during the packaging process. During packaging, the alumina powder to be packaged is fed into the collecting hopper, so that the alumina powder falls into the packaging bag below along the drop pipe, and then the sealing mechanism is used to heat-press and seal the position where the top of the packaging bag is connected to the packaging paper, and the sealing mechanism cuts the sealing position into two parts, upper and lower, to complete the sealing of the top opening of the packaging bag and the cutting between the packaging papers, and at the same time, the bottom of the cylindrical packaging paper is sealed to form a new packaging bag.

[0004] When the powder falls from the drop tube into the packaging bag below, the powder will generate dust when it touches the bottom. The raised powder will be adsorbed on the inner wall of the packaging material and the lower end face and edge of the drop tube. If it happens to be adsorbed on the place where sealing is required, it will affect the sealing effect. In severe cases, it will lead to a loose seal, causing powder leakage from the package. In the above-mentioned technology, a sealing protection mechanism is provided at the drop tube to make the packaging bag close to the outer wall of the drop tube, which can only prevent dust from entering the gap between the drop tube and the packaging bag. The powder will still be adsorbed on the lower end face and edge of the drop tube. When the packaging bag moves downward, the inner wall of the packaging bag will rub against the edge of the lower end face of the drop tube, causing the powder on the lower end face of the drop tube to adhere to the inner wall of the packaging bag, and the dust in the packaging bag will also contact the packaging bag at the place where sealing is required, thus affecting the sealing effect. In severe cases, it will lead to a loose seal, causing powder leakage from the package. Summary of the invention

[0005] The invention provides a potassium monopersulfate compound filling device, aiming to solve the technical problem in the related art that powder is adsorbed on the sealing part of the packaging bag and affects the sealing effect.

[0006] A potassium monopersulfate compound filling device comprises a frame, a limiting ring, a reeling mechanism, an edge sealing mechanism, a sealing mechanism and a drop pipe, wherein the front side of the limiting ring is provided with an avoidance groove running through from top to bottom, and further comprises: The folding mechanism includes a lifting assembly, a horizontal moving assembly installed at the lifting end of the lifting assembly, a rotating rod installed at the moving end of the horizontal moving assembly, and a driving assembly for driving the rotating rod to rotate, and two thin rods are installed at one end of the rotating rod; The conveying mechanism includes a conveying belt 1 and two conveying belts 2 arranged on the lower side of the edge sealing mechanism and attached to each other, and there is an overlapping area between the conveying belt 1 and the conveying belt 2 in the height direction; The horizontal moving device drives the rotating rod to slide toward the plastic film, and the edge of the plastic film enters between the two thin rods. The driving mechanism drives the rotating rod to rotate, and the two thin rods drive the plastic film to fold to form an overlapping area. The lifting device makes the rotating rod move downward along with the plastic film, so that the overlapping area is close to the conveyor belt 1. The horizontal moving device drives the rotating rod to rotate the center line of the plastic film, so that the thin rod drives the edge of the plastic film to fold. Finally, the thin rod moves away from the plastic film, and the conveyor belts 1 and 2 drive the overlapping area of ​​the plastic film to pass over the edge sealing mechanism. The pull-down mechanism is used to pull the packaging bag downward before sealing the packaging bag, so that the overlapping area is unfolded, and the sealing mechanism seals the unfolded part.

[0007] By setting up a folding mechanism, the plastic film can be folded to form an "S"-shaped overlapping area. When the powder is filled into the lower packaging bag and the upper plastic film moves downward, a part of the plastic film in the overlapping area does not contact the air and the drop tube, and remains clean. When sealing is required, the overlapping area of ​​the plastic film is pulled open for sealing.

[0008] Preferably, the thin rod is rotatably mounted on the rotating rod.

[0009] The rotating installation can reduce the friction resistance between the plastic film and the thin rod when folding.

[0010] Preferably, the lifting assembly includes a mounting frame slidably mounted on the frame and a driving source 2 for driving the mounting frame to lift.

[0011] Preferably, the horizontal moving component includes a push plate slidably mounted on the frame, a slider slidably mounted on the mounting frame and a driving source for driving the push plate to move, a locking component for locking the slider to move on the mounting frame is provided between the slider and the mounting frame, a rotating rod is passed through the slider, an inclined surface abutting against the rotating rod is provided on the push plate, and a locking component for locking the rotating rod to move on the slider is provided between the rotating rod and the slider.

[0012] Preferably, the locking assembly 1 includes an elastic telescopic block 1 arranged on the slider, and a limiting hole 1 and a limiting hole 2 cooperating with the elastic telescopic block 1 are respectively provided at the front and rear ends of the mounting frame, and an elastic member 1 for resetting the slider is provided between the slider and the mounting frame. When the driving mechanism drives the rotating rod to rotate, the elastic telescopic block 1 withdraws from the limiting hole 1, and after the thin rod drives the edge of the plastic film to fold, the elastic telescopic block 1 is stuck in the limiting hole 2.

[0013] Preferably, the locking assembly 2 includes an elastic telescopic block 2 arranged on the rotating rod, a limiting hole 3 cooperating with the elastic telescopic block 2 is opened on the slider, and an elastic member 2 is arranged between the rotating rod and the slider to reset the rotating rod away from the plastic film. When the driving mechanism drives the rotating rod to rotate, the elastic telescopic block 2 is stuck in the limiting hole 3.

[0014] Preferably, a baffle plate 2 is provided on the lower side of the mounting frame, and an unlocking rod 2 is slidably provided in the limiting hole 3. When the mounting frame moves downward, after the bottom end of the slider abuts against the baffle plate 2, the unlocking rod 2 moves upward to retract the elastic telescopic block 2 into the rotating rod.

[0015] Preferably, the driving assembly includes a protrusion arranged on the slider, and a limiting groove cooperating with the protrusion is opened on the rotating rod, and the limiting groove includes a first section extending in the left-right direction, a second section connected to the right end of the first section and deflected backward 180°, a third section extending to the left from the right end of the second section, and a fourth section connected to the third section and deflected forward 180°.

[0016] Preferably, the sealing mechanism includes a sealing plate slidably arranged on the frame for sealing, and the pull-down mechanism includes a pressing plate, the sealing plate is provided with an inclined sliding groove, the pressing plate is slidably installed in the sliding groove, and an elastic member three is arranged in the sliding groove to make the pressing plate be located at the top of the sliding groove. At this time, the right end face of the pressing plate exceeds the sealing plate, which is used to press the overlapping area to the lower side in advance and press the packaging bag to drive the packaging bag downward through friction, thereby pulling open the overlapping area.

[0017] By setting a pull-down mechanism, the overlapping area of ​​the plastic film is pulled apart for heat-pressing sealing.

[0018] A method for using a potassium monopersulfate complex filling device comprises the following steps: S1, the plastic film on the roll extends downward after passing through the guide roller group, and is flattened and pressed against the front end surface of the blanking tube; S2, the plastic film passes through a folding mechanism, so that a section of the plastic film in the length direction is folded in the vertical direction to form overlapping areas of a three-fold structure, and the overlapping areas on the plastic film are arranged at equal intervals; S3, the edge sealing mechanism heat-seals the two edges of the plastic film together; S4, the sealing mechanism heat-seals the upper and lower openings of the plastic film together.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. The plastic film is folded by a folding mechanism to form an overlapping area, so that the inner sides of the plastic film at the sealing portion are superimposed on each other, thereby preventing the area from contacting the air and preventing the powder falling in the drop tube from being adsorbed at the sealing portion; 2. By setting up a pull-down mechanism, before hot pressing the sealed area, the lower side of the overlapping area is pre-pressed to prevent the air with powder from flowing upward. Then the packaging bag is pulled downward to expand the overlapping area above the packaging bag for hot pressing. BRIEF DESCRIPTION OF THE DRAWINGS

The folding mechanism 6 is arranged below the unwinding mechanism 2, and is used to fold the plastic film 10 to form an overlapping area. The limiting shaping mechanism 3 is located below the folding mechanism 6, and is used to bend the plastic film 10 into a cylindrical shape. The edge sealing mechanism 4 is arranged at the front side of the frame 1, and is used to hot-press and composite the two side edges of the cylindrical plastic film 10 together. The sealing mechanism 5 is arranged at the lower side of the edge sealing mechanism 4, and is used to seal the upper and lower openings of the cylindrical plastic film 10 so that the plastic film 10 is sealed to form a packaging bag. The feeding mechanism 7 is used to fill the powder into the packaging bag, and the conveying mechanism 8 is used to drive the plastic film 10 to move downward.

[0034] like Figure 1 As shown, the unwinding mechanism 2 includes a winding roller and a guide roller group. The winding roller is rotatably installed on the top of the frame 1, and the plastic film 10 is wound on the winding roller. The guide roller group is arranged below the winding roller to guide the plastic film 10 on the winding roller to the packaging mechanism below.

The two side plates 41 are respectively located on the left and right sides of the blanking tube 71, and the rear ends of the two side plates 41 are fixedly connected to the front end surface of the frame 1. A connecting rod 46 connecting the two side plates 41 is installed between the two side plates 41. The driving source 42 is a motor. The motor is installed on the side plate 41 on the left side of the blanking tube 71. A lead screw 45 extending in the left and right directions is installed at the output end of the motor. The lead screw 45 is simultaneously penetrated on the two side plates 41 and is rotatably matched with the two side plates 41. The thread on the lead screw 45 is divided into left and right sides with the blanking tube 71 as the boundary. The two sections of the thread have opposite directions.

The push plates 44 and the heat sealing plates 43 are connected by a compression spring 47. When the motor 1 rotates forward, the two push plates 44 approach each other, and then the compression spring 47 pushes the heat sealing plates 43 to approach each other, so that the two side edges of the cylindrical plastic film 10 are hot-pressed and compounded together.

[0038] like Figure 1-Figure 7 , Fig.10As shown, the folding mechanism 6 includes two folding components 62, a lifting component and a horizontal moving component. The lifting component is used to drive the folding component 62 to move up and down, and the horizontal moving component is used to drive the folding component 62 to move toward the plastic film 10, so as to fold the plastic film 10 flattened and tightly attached to the blanking tube 71.

[0039] like Figure 3-Figure 7 , Fig.10 As shown, the lifting assembly includes a mounting frame 61 and a second driving source. The rear end of the mounting frame 61 is slidably mounted on the front end surface of the frame 1 along the up-down direction. The second driving source includes a second motor 67 fixedly mounted on the front end surface of the frame 1 and a second lead screw connected to the output end of the second motor 67. The second lead screw extending along the up-down direction is passed through the mounting frame 61, and the mounting frame 61 and the second lead screw are threadedly matched.

[0040] like Figure 3-Figure 7 , Fig.10 As shown, the folding component 62 is arranged on the mounting frame 61, and the left and right halves of the folding component 62 are symmetrically arranged. The left and right halves of the folding component 62 each include a rotating rod 621 and two thin rods 624.

The rotating rod 621 is connected to the moving end of the horizontal moving component, and a driving component is arranged on the rotating rod 621. When the horizontal moving component drives the rotating rod 621 to move toward the plastic film 10, after the plastic film 10 enters between the two thin rods 624, the driving component drives the rotating rod 621 to rotate 180° on the slider 614, so that the plastic film 10 is stretched downward and then wrapped in an "S" shape on the two thin rods 624, so that the plastic film 10 forms an overlapping area.

[0041] like Figure 3-Figure 7 , Fig.10As shown, the horizontal moving assembly includes an arc plate and two sliders 614, the arc plate surrounds the outside of the drop tube 71 and is fixed to the mounting frame 61, and two arc-shaped track grooves are opened on the lower end surface of the arc plate, and the two arc-shaped track grooves are respectively located on the left and right sides of the drop tube 71, and the two sliders 614 are respectively slidably installed in the two track grooves, and elastic members 1 are arranged in the two track grooves, and the elastic members 1 are arc-shaped compression springs 2, and the two ends of the compression springs 2 are respectively connected to the slider 614 and the mounting frame 61, and the slider 614 is located at the front end of the track groove when the compression springs 2 are relaxed, and the rotating rod 621 is penetrated in the slider 614 along the left and right directions, and an elastic member 2 is installed between the end of the rotating rod 621 away from the center of the arc plate and the slider 614, and the elastic member 2 is a compression spring 3 622, and the end of the rotating rod 621 away from the center of the arc plate is hemispherical. Taking the push plate 44 on the right side of the center of the arc plate as an example, the push plate 4 The top of 4 is provided with an inclined surface 48 abutting against the right end of the rotating rod 621, and the rear end of the inclined surface 48 is a straight surface extending backward in the front-to-back direction. The slider 614 is provided with a locking component 1 for locking the slider 614 in the track groove, and the rotating rod 621 is provided with a locking component 2 for locking the rotating rod 621 and the slider 614. When the right push plate 44 moves to the left, the push plate 44 moves from right to left in the slider 614 through the rotating rod 621 pushed by the inclined surface 48. When the rotating rod 621 rotates 180°, the locking component 1 unlocks the slider 614 and the track groove, and then the rotating rod 621 drives the slider 614 to move backward in the track groove under the action of the inclined surface 48, so that the thin rod 624 drives the edge of the plastic film 10 to fold, and then the locking component 1 locks the slider 614 in the track groove again, and the locking component 2 locks the rotating rod 621 in the slider 614.

[0042] like Figure 3-Figure 7 , Fig.10 As shown, the locking component 1 includes an elastic telescopic block 1 615 installed on the top of the slider 614 and popping up upward, and the front and rear ends of the track groove are respectively provided with a limiting hole 1 611 and a limiting hole 2 612 that penetrates the mounting frame 61 in the up and down directions. When the slider 614 is located at the front end of the track groove, the elastic telescopic block 1 615 is stuck in the limiting hole 1 611. When the thin rod 624 drives the edge of the plastic film 10 to fold, the elastic telescopic block 1 615 is stuck in the limiting hole 2 612. A baffle 1 63 installed on the frame 1 is provided above the mounting frame 61, and an unlocking rod 1 631 for inserting into the limiting hole 2 612 to squeeze the elastic telescopic block 1 615 downward is installed on the lower end surface of the baffle 1 63. When the mounting frame 61 moves upward and abuts against the baffle 1 63, the unlocking rod 1 631 is inserted into the limiting hole 2 612 to squeeze the elastic telescopic block 1 615 downward, thereby unlocking the slider 614 and the track groove.

When the thin rod 624 drives the edge of the plastic film 10 to fold, the elastic telescopic block 2 623 is stuck in the limiting hole 3, and a baffle 2 64 installed on the frame 1 is provided below the mounting frame 61. When the mounting frame 61 moves downward and abuts against the baffle 2 64, the unlocking rod 2 616 is inserted into the limiting hole 3 to squeeze the elastic telescopic block 2 623 upward, thereby unlocking the slider 614 and the rotating rod 621, and the slider 614 is reset under the action of the compression spring 2.

[0044] like Figure 3-Figure 7 , Fig.10 As shown, the rotating assembly includes a protrusion installed on the slider 614, a limiting groove 625 is provided on the rotating rod 621, and the protrusion is inserted into the limiting groove 625. The limiting groove 625 includes a first section extending in a straight line in the left-right direction, a second section connected to the right end of the first section and gradually deflected 180° backward, a third section extending in a straight line to the left from the right end of the second section, and a fourth section connected to the third section and gradually deflected 180° forward. When the rotating rod 621 moves from right to left in the slider 614, the rotating rod 621 first moves to the left under the action of the first section of the limiting groove 625. At this time, the plastic film 10 enters between the two thin rods 624, and then the rotating rod 621 continues to move. When continuing to move to the left, the rotating rod 621 rotates 180° counterclockwise under the action of the second section of the limiting groove 625, so that the two thin rods 624 drive the plastic film 10 to stretch downward and then wrap around the two thin rods 624 in an "S" shape, so that the plastic film 10 forms an overlapping area. When the unlocking rod 2 616 is inserted into the limiting hole 3, the rotating rod 621 moves to the right under the action of the compression spring 3 622. At this time, the protrusion slides to the left on the third section of the limiting groove 625. When the rotating rod 621 moves to the right, the thin rod 624 disengages from the overlapping area of ​​the plastic film 10. When the protrusion moves along the fourth section of the limiting groove 625, the rotating rod 621 rotates 180° in the opposite direction to complete the reset.

The plastic film 10 is located between the conveyor belt 1 82 and the roller 84, and the plastic film 10 is tightly attached to the conveyor belt 1 82 and the roller 84. When the two sides of the plastic film 10 are hot-pressed and laminated together, the mounting frame 61 moves downward, so that the thin rod 624 drives the overlapping area of ​​the plastic film 10 to move downward into between the conveyor belt 1 82 and the roller 84.

[0047] The conveying assembly 2 includes four wheels 2 rotatably mounted on the frame 1 and a motor 3 (not shown in the figure) mounted in the frame 1.

The output end of the motor 3 is connected to the wheels 2 on the two conveyor belts 2 83 respectively. The two conveyor belts The two conveying assemblies 83 press the heat-sealed part of the plastic film 10 and drive it to move downward. When the two heat-sealing plates 43 heat-seal the plastic film 10, the conveying assembly 1 and the conveying assembly 2 drive the overlapping area on the plastic film 10 to move to the lower side of the heat-sealing plate 43. The heat-sealing plate 43 heat-seals the plastic film 10, and the lower end surface of the heat-sealing plate 43 is located above the lower end surface of the blanking tube 71. The two groups of conveying assemblies below the heat-sealing plate 43 and the conveying assemblies on the front side of the blanking tube 71 ensure that the upper and lower ends of the overlapping area of ​​the plastic film 10 are always pressed by the conveying assemblies to prevent them from unfolding.

[0048] like Figure 2-Figure 4 , Figure 8 , Fig. 9 As shown, the sealing mechanism 5 includes a supporting frame 51 and two sealing cylinders 52. The supporting frame 51 is fixedly installed on one side of the frame 1 and is located below the blanking tube 71.

Taking the pull-down mechanism 9 in front of the drop tube 71 as an example, the pull-down mechanism 9 includes two sliding seats and a clamping plate 91. An inclined slide groove is provided on the upper front-to-back direction of the left and right end surfaces of the sealing plate 53. The sliding seat is installed in the slide groove. An elastic member three is provided in the slide groove. The elastic member three is a compression spring four 92. The two ends of the compression spring four 92 are respectively connected to the sliding seat and the sealing plate 53. The compression spring four 92 is used to make the sliding seat located at the upper end of the slide groove. The left and right ends of the clamping plate 91 are hinged on the two sliding seats. A torsion spring (not shown in the figure) connected to the sliding seat is installed at the hinge axis of the clamping plate 91. The torsion spring is used to make the clamping plate 91 is inclined toward the sealing side, so that when sealing, the sealing cylinder 52 pushes the two sealing plates 53 closer to each other. At this time, the top ends of the two pressing plates 91 first abut against the packaging bag, and then the two pressing plates 91 gradually rotate to make the two opposite surfaces of the pressing plates 91 close to each other, thereby squeezing the air near one end of the overlapping area in the packaging bag downward, and then as the two sealing plates 53 gradually approach, the two pressing plates 91 gradually move downward under the guidance of the inclined slide groove, and drive the packaging bag to be pulled downward, thereby pulling the overlapping area of ​​the packaging bag apart, and finally the sealing plates 53 abut against each other, and the overlapping area that has not been in contact with the air containing the powder is hot-pressed and sealed.

[0050] The implementation method of a potassium monopersulfate complex filling device of the present invention is as follows: S1, first, the plastic film 10 on the roll extends downward after passing through the guide roller group, and is flattened and pressed against the front end surface of the blanking tube 71. When the plastic film 10 extending downward passes through the gap, it is bent and coated on the surface of the blanking tube 71 in a cylindrical shape; S2, then the motor 1 drives the two push plates 44 to move closer to each other, and at the same time, the push plate 44 pushes the rotating rod 621 to move toward the blanking tube 71 in the slider 614 through the inclined surface 48. The rotating rod 621 first slides toward the blanking tube 71 under the action of the first section of the limiting groove 625, so that the plastic film 10 enters between the two thin rods 624. Then, when the rotating rod 621 continues to move to the left, it rotates 180° counterclockwise under the action of the second section of the limiting groove 625, so that the plastic film 10 forms an overlapping area, and then the push plate When the push plate 44 continues to move to the left, the elastic expansion block 1 615 breaks through the limit of the limit hole 1 611, so that the inclined surface 48 pushes the rotating rod 621 to slide backward along the track groove. At this time, the two thin rods 624 drive the plastic film 10 forming the overlapping area to bend backward from the left and right sides of the blanking tube 71 until the elastic expansion block 1 615 is inserted into the limit hole 2 612. At this time, the heat sealing plates 43 are pressed against each other, and the upper and lower openings of the cylindrical plastic film 10 are heat-pressed and laminated together, and then the push plate 44 is reset; S3. When the filling of the packaging bag below is completed, the motor 2 67, the motor 3 and the motor 4 are started at the same time, the conveying mechanism 8 drives the plastic film 10 to move downward, and the thin rod 624 drives the overlapping area of ​​the plastic film 10 to move downward into between the conveyor belt 1 82 and the roller 84. When the bottom end of the slider 614 abuts against the baffle 2 64, the unlocking rod 2 616 moves upward to squeeze the elastic telescopic block 2 623, so that the elastic telescopic block 2 623 is received in the rotating rod 621, and then the rotating rod 621 moves to the right under the action of the compression spring 3 622 to complete the reset. At this time, the thin rod 624 1 and the thin rod 624 2 are out of contact with the plastic film 10, and then the mounting frame 61 moves upward. When the unlocking rod 1 631 is inserted into the limiting hole 2 612, the slider 614 is reset under the action of the compression spring 2, and finally the mounting plate moves downward a short distance to make the unlocking rod 1 631 disengage from the limiting hole 2 612. S4. Finally, the sealing cylinder 52 pushes the two sealing plates 53 toward each other. At this time, the top ends of the two pressing plates 91 first abut against the packaging bag, and then the two pressing plates 91 gradually rotate to make the two opposite surfaces of the pressing plates 91 close to each other, thereby squeezing the air near one end of the overlapping area in the packaging bag downward. Then, as the two sealing plates 53 gradually move, the two pressing plates 91 gradually move downward under the guidance of the inclined slide groove, and drive the packaging bag to be pulled downward, thereby pulling the overlapping area of ​​the packaging bag open. Finally, the sealing plates 53 abut against each other to perform hot pressure sealing on the overlapping area of ​​the plastic film 10 that has not been in contact with the air containing the powder.
