Description

Technical Field

[0001] The present invention relates to the technical field of plastic packaging film conveying, and specifically provides a conveying device for plastic packaging film production. Background Art

[0002] Plastic packaging film is a kind of packaging material widely used in industries such as food, medicine, and daily necessities. It is usually made of plastic materials such as PE (polyethylene), PP (polypropylene), PET (polyester), and PVC (polyvinyl chloride). It has good transparency, toughness, moisture resistance, and certain barrier properties, and can effectively protect products, prevent pollution and damage. The conveying device for plastic packaging film production is mainly used for conveying, tensioning, cooling, printing, cutting, winding and other processes on the production line to ensure the smooth operation of the film material during the production process.

[0003] In the last step of production, the wound plastic packaging film needs to be sleeved with a tubular protective bag. This step usually uses clamping equipment to clamp the film roll, and then waits for manual workers to manually insert the excess parts at both ends of the packaging bag into the inside of both ends of the film roll. However, this operation method requires the production line to pause and wait for manual operation, and the packaging process of each film roll needs to stop the machine, which interrupts the continuity of the production line and affects the overall production efficiency. Moreover, the rolls of plastic packaging film are usually large and heavy, and manual insertion of the excess parts at both ends of the packaging bag requires a certain amount of force and skill, which increases the labor intensity of workers. The insertion force and depth are uneven, which may lead to uneven packaging tightness and affect the stability of subsequent storage and transportation.

[0004] In addition, during the production and conveying process of plastic packaging film, due to the high-speed friction of conveyor belts, rollers, and winding processes, and the fact that plastic materials themselves are electrical insulators and difficult to self-dissipate static electricity, static electricity accumulates severely. The static electricity problem will cause the film material to easily adsorb dust and plastic debris, affecting the surface quality of the product, and causing the film rolls to stick together, affecting normal conveying and subsequent packaging. To eliminate static electricity, the currently common static electricity elimination methods mainly include static electricity elimination rods, which are usually installed on the conveyor line and neutralize the static electricity on the plastic film by releasing positive and negative ions. During high-speed conveying, the static electricity on the plastic film accumulates rapidly, and the elimination ability of a single static electricity elimination rod is limited and difficult to keep up with the static electricity accumulation speed of the film material, resulting in static electricity residue in some areas and incomplete elimination of static electricity. Summary of the Invention

[0005] The present invention provides a conveying device for plastic packaging film production, which solves the technical problems that after the plastic packaging film is wound, it needs to be sleeved with a protective bag, the current method requires the machine to stop and wait for manual insertion of the bag mouth, and the packaging tightness is uneven, affecting storage and transportation. At the same time, during the conveying process, due to friction and material characteristics, static electricity is easily accumulated, adsorbing dust and debris, resulting in film roll adhesion. The existing static electricity elimination rods have limited effects and are difficult to completely eliminate static electricity, affecting product quality.

[0031] In order to make the above-mentioned objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figure 1 and Figure 3, the present invention provides a technical solution: a conveying device for plastic packaging film production, which includes a workbench 1, a guide rail beam 2 installed on the ceiling of the working workshop, and two roller frame plates 3 fixedly connected symmetrically left and right to the upper end surface of the workbench 1. Between the two roller frame plates 3, there is jointly provided an electrostatic eliminator 4 for multiple elimination of static electricity on the surface of the conveying packaging film. The right end surface of the left roller frame plate 3 is rotatably connected to a winding roller 5. A clamping mechanism 6 is slidably arranged on the guide rail beam 2 for clamping and transferring the wound packaging film roll and at the same time inserting a tubular packaging bag into the inside of the packaging film roll for finishing. A transfer mechanism 7 is arranged on the workbench 1 for transferring the packaging film roll from the winding roller 5 to the position of the clamping mechanism 6. A guide rail seat is fixedly connected to the upper end surface of the workbench 1 and is located directly below the winding roller 5. An electric slider is slidably connected to the guide rail seat, and a push plate 10 is fixedly connected to the upper end surface of the electric slider.

[0033] Please refer to Figure 1 , Figure 3 and Figure 5 , in this embodiment, the electrostatic eliminator 4 includes an electrostatic ion bar 41, a diversion pipe 42, a shunt pipe 43, a spray nozzle 44, an ion blower 45, a connecting pipe 46, and a cleaning component 47. Two electrostatic ion bars 41 are symmetrically rotatably connected between the two roller frame plates 3. Two diversion pipes 42 are symmetrically and fixedly connected together between the two roller frame plates 3. A number of shunt pipes 43 are equidistantly connected to the front and rear sides of the diversion pipe 42. The end of the shunt pipe 43 far from the diversion pipe 42 is connected to a spray nozzle 44. The front and rear rows of shunt pipes 43 are arranged in a staggered manner, and the upper and lower corresponding shunt pipes 43 are arranged symmetrically. A connecting pipe 46 that is simultaneously connected to the two diversion pipes 42 is fixedly connected and embedded in the right roller frame plate 3. An ion blower 45 is fixedly connected to the right end of the connecting pipe 46. Cleaning components 47 for removing dust electrostatically adsorbed on the surface of the packaging film and film debris during trimming are arranged on both diversion pipes 42. The cleaning component 47 includes a rectangular sliding frame 471 and a sponge wiping block 472. Strip-shaped placement grooves are opened on the opposite sides of the two diversion pipes 42. A rectangular sliding frame 471 is slidably connected in the strip-shaped placement grooves. A number of sponge wiping blocks 472 are equidistantly fixedly connected to the opposite sides of the two rectangular sliding frames 471. A driving member for driving the rectangular sliding frame 471 to move is arranged inside the diversion pipe 42.

[0034] Please refer to Figure 5 and Figure 6, the driving member includes a plurality of mounting grooves 473 equidistantly formed in the inner cavity of the diversion pipe 42. A turntable 474 is rotatably connected in the mounting groove 473. A plurality of pneumatic blades 475 are circumferentially and equidistantly fixedly connected to the outer wall of the turntable 474. A plurality of through grooves corresponding to the mounting grooves 473 and communicating the mounting grooves 473 with the strip-shaped placement grooves are equidistantly formed in the diversion pipe 42. A telescopic connecting rod 476 is hinged to the front side of the turntable 474. The lower end of the telescopic connecting rod 476 is fixedly connected to the rectangular sliding frame 471. A guide rod 477 passing through the telescopic connecting rod 476 is fixedly connected between the left and right cavity walls of the mounting groove 473, and the telescopic connecting rod 476 is slidably connected to the outside of the guide rod 477.

[0035] During the transportation process of the plastic packaging film, it successively passes between two static ion bars 41 and between two diversion pipes 42. By controlling the operation of the static ion bars 41, the static electricity on the plastic packaging film is initially eliminated. At the same time, the ion blower 45 is controlled to operate to release positive and negative ion airflows. The positive and negative ion airflows are blown into the diversion pipe 42 through the connecting pipe 46 by the wind force. Then, the positive and negative ion airflows respectively flow into the laterally equidistantly distributed shunt pipes 43, and finally are blown onto the plastic film from the jet nozzles 44 to neutralize the static electricity on the surface of the plastic packaging film. The front and rear staggered jet nozzles 44 are used to ensure that the positive and negative ion airflows can fully blow on the surface of the plastic packaging film to avoid areas where the blowing is missed. When the positive and negative ion airflows enter the inner cavity of the diversion pipe 42 and flow, they will also blow the pneumatic blades 475, thereby indirectly driving the turntable 474 to rotate. The turntable 474 then drives the telescopic connecting rod 476 to perform synchronous reciprocating vertical and horizontal movements. The guide rod 477 is used to make the telescopic connecting rod 476 drive the rectangular sliding frame 471 to move synchronously when performing horizontal reciprocating movements. The rectangular sliding frame 471 then drives the sponge wiping block 472 to perform horizontal reciprocating movements to remove the dust or plastic debris attached to the surface of the plastic packaging film.

[0036] In addition, a motor can also be installed at the front of the diversion pipe 42. The output shaft of the motor passes through the diversion pipe 42 and is fixedly connected to the disc. By controlling the motor to drive the disc to rotate, the pneumatic blades 475 blown by the positive and negative ion airflows can also be used as an auxiliary power source.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4In this embodiment, the transfer mechanism 7 includes a support column 71 fixedly connected to the upper end surface of the workbench 1 through a base, a swivel is rotatably connected to the outside of the support column 71, a bearing column 72 is fixedly connected to the outside of the swivel, an annular groove is provided on the outside of the bearing column 72, and a number of spring telescopic columns 73 are fixedly connected to the left and right groove walls of the annular groove at equal intervals in the circumferential direction, the proximal ends of the laterally opposite spring telescopic columns 73 are hinged with connecting rods 74, and the ends of the laterally opposite connecting rods 74 are hinged with an arc-shaped top plate 75, the winding roller 5 is fixedly connected to the shaft head 8, and the left end of the bearing column 72 is slidably connected to the shaft sleeve 9 that cooperates with the shaft head 8.

[0038] Before the winding roller 5 is operated, the tube used for winding the plastic packaging film is first sleeved on the outside of the winding roller 5, and then the bearing column 72 is turned to rotate to the same axial position as the winding roller 5, and then the shaft sleeve 9 is pushed horizontally to slide on the outside of the shaft head 8 to avoid the right end of the winding roller 5 being in a suspended state, and then the winding roller 5 is controlled to rotate and drive the tube to run synchronously, and the tube rotates to wind up the plastic packaging film. When the tube is wound, the plastic packaging film is cut by an external slitting device, and then the electric slider is controlled to slide to the right. The electric slider then drives the push plate 10 to move right, and the push plate 10 then contacts the left side of the tube and pushes the tube to move right synchronously until the tube moves to the right and is sleeved on the outside of the bearing column 72. At this time, the spring telescopic column 73 pushes the arc-shaped top plate 75 to contact the inner wall of the tube through the connecting rod 74. Then, the shaft sleeve 9 is manually pushed to move right and separate from the shaft head 8, and then the bearing column 72 is pushed to rotate counterclockwise ninety degrees around the support column 71, so that the bearing column 72 drives the tube wrapped with the plastic packaging film to move to the bottom of the clamping mechanism 6.

[0039] See also Figure 1 , Figure 7 and Figure 8In this embodiment, the clamping mechanism 6 includes a fixed seat 61 slidably mounted on the guide rail beam 2 through a telescopic arm 69, and the lower end surface of the fixed seat 61 is hinged with four clamping rods 62 distributed in a matrix shape, and the lower end of the clamping rod 62 is fixedly connected with an arc-shaped clamping plate 63, and a slide cylinder 64 arranged along its own axis direction is embedded and fixedly connected in the arc-shaped clamping plate 63, and a U-shaped support rod 65 is slidably connected in the slide cylinder 64, and a top spring is fixedly connected between the U-shaped support rod 65 and the slide cylinder 64 through a connecting block, and one end of the U-shaped support rod 65 close to the axis of the arc-shaped clamping plate 63 is fixedly connected through a fixing block for clamping the cylinder The arc-shaped push strip 66 is inserted into the packaging film roll of the packaging bag, and the U-shaped support rod 65 is located at the end of the inner cavity of the slide cylinder 64 and is fixedly connected with a cable 67. A winding and pulling component 68 for winding and retracting the cable 67 and indirectly driving the arc-shaped push strip 66 to move is provided between the left and right cables 67 and the telescopic arm 69. The telescopic arm 69 includes an outer bearing sleeve 691 slidably connected to the guide rail beam 2 and an inner bearing block 692 slidably connected to the outer bearing sleeve 691, and an electric telescopic rod 693 is fixedly connected between the upper end of the inner bearing block 692 and the outer bearing sleeve 691.

[0040] See also Figure 7 The winding and pulling assembly 68 includes a reel 681, a gear 682, a pulley 683 and a rack 684. The outer side of the inner bearing block 692 is rotatably connected to a rotating shaft, and the outer side of the rotating shaft is fixedly connected to the reel 681. The end of the cable 67 away from the U-shaped support rod 65 slides through the fixed seat 61 and is wound and fixedly connected to the outside of the reel 681. The outer side of the inner bearing block 692 and located directly above the reel 681 is rotatably connected to a gear 682. The gear 682 and the reel 681 are connected by a pulley 683. The left cavity wall of the outer bearing sleeve 691 is fixedly connected to a rack 684 that meshes with the gear 682.

[0041] The electric telescopic rod 693 is controlled to extend and push the inner bearing block 692 to move downward, and the inner bearing block 692 then drives the fixed seat 61 to move downward, and the fixed seat 61 drives the clamping rod 62 and the arc clamping plate 63 to move downward until the arc clamping plate 63 is sleeved on the outside of the packaging film roll located directly below it, and then the clamping rod 62 is controlled to retract and drive the arc clamping plate 63 to move and clamp on the outside of the packaging film roll. The arc clamping plate 63 clamps and drives the arc push strip 66 to move to the end position of the packaging film roll through the slide cylinder 64 and the U-shaped support rod 65, and then the control The outer bearing sleeve 691 moves laterally on the guide beam 2, and then indirectly drives the packaging film roll to move laterally, so that the packaging film roll is removed from the outside of the bearing column 72. When the arc clamping plate 63 moves laterally and drives the arc push strip 66 to pass the position of the connecting rod 74, the arc push strip 66 will contact the connecting rod 74 and squeeze it to move toward the axis of the bearing column 72. The connecting rod 74 then drives the arc top plate 75 to move synchronously, so that the circumferentially distributed arc top plates 75 shrink synchronously, thereby avoiding interference between the arc push strip 66 and the arc top plates 75.

[0042] Then, control the electric telescopic rod 693 to contract, driving the inner bearing block 692 to move upward. The inner bearing block 692 then drives the gear 682 to move upward. After the gear 682 moves upward for a certain distance, it will contact and mesh with the rack 684. Then, as the gear 682 continues to move upward, it rotates under the action of the rack 684. The gear 682 then drives the rotating shaft to rotate through the belt pulley member 683. The rotating shaft then drives the winding drum 681 to rotate. The winding drum 681 rotates to wind up the cable 67. The cable 67 then pulls the U-shaped support rod 65 to slide in the sliding cylinder 64. The U-shaped support rod 65 drives the arc-shaped push bar 66 to move. The front and rear arc-shaped push bars 66 move closer to each other, pushing the redundant part of the tubular packaging tape into the tube.

[0043] When the outer bearing sleeve 691 moves horizontally along the guide beam 2 to directly above the transfer device, control the electric telescopic rod 693 to extend, driving the inner bearing block 692 to move downward. The inner bearing block 692 then drives the gear 682 to move downward. When the gear 682 moves downward, it meshes with the rack 684 and rotates in the reverse direction. The gear 682 then drives the winding drum 681 to rotate in reverse through the belt pulley member 683. The winding drum 681 then releases the cable 67, pushing the U-shaped support rod 65 to move back to its original position in the sliding cylinder 64. The U-shaped support rod 65 then drives the arc-shaped push bar 66 to move, moving the arc-shaped push bar 66 out of the tube. Then, when the packaging film roll is placed on the transfer device, control the clamping rod 62 to move outward and expand. The clamping rod 62 then drives the clamping plate to move and separate from the packaging film roll. Thus, the wound plastic packaging film can be clamped and transferred while automatically stuffing the redundant packaging bags at both ends of it.

[0044] During operation, first, sleeved the tube used for winding the plastic packaging film on the outside of the winding roller 5. During the production and transportation of the plastic packaging film, use the static eliminator 4 to perform multiple static elimination treatments on the plastic packaging film. Then, control the winding roller 5 to rotate, driving the tube to rotate. The tube winds up the plastic packaging film. Then, through the transfer mechanism 7, move the plastic packaging film roll to a position below the clamping mechanism 6, and sleeve the tubular packaging bag on the outside of the plastic packaging film roll. Then, control the clamping mechanism 6 to operate to clamp the plastic packaging film roll during the transfer process, and stuff the redundant parts at both ends of the tubular packaging bag into the inside of the tube. Finally, place the wound plastic packaging film roll on the transfer device.
