Description

Technical Field

[0001] The present invention relates to the technical field of curing equipment, and more specifically, to a curing equipment and method for high-barrier antibacterial plastic packaging films. Background Art

[0002] The high-barrier antibacterial plastic packaging film curing equipment is designed specifically to improve the barrier and antibacterial properties of packaging materials. Through a precise temperature control system and a circulating hot air device, the film material can complete the crosslinking and curing of adhesives and antibacterial agents in an environment of 50 - 70 °C. The curing time can be adjusted according to the thickness of the film material, and it is equipped with a humidity monitoring and waste gas treatment module to ensure a uniform and efficient curing process.

[0003] The patent with the application number CN202420561074.1 discloses a plastic composite film curing equipment, including a curing chamber. Inside the curing chamber, there is a conveying mechanism, which includes: a conveying component arranged inside the curing chamber; multiple connecting rods arranged equidistantly on the conveying component; push rods, with multiple push rods respectively connected to multiple connecting rods, and an automatic limiting component. The motor can drive multiple push rods to move horizontally through the conveying component, so as to push multiple composite film rolls one by one, eliminating the need for manual placement.

[0004] Existing equipment has obvious defects in material transfer and heat insulation design. In the transfer process, manual handling of high-barrier antibacterial plastic packaging film rolls is relied on, especially when entering and leaving the curing chamber in a high-temperature environment. This not only poses potential safety hazards in operation, but also has low manual operation efficiency and loose process connection, making it difficult to meet the requirements of large-scale continuous production. In terms of heat insulation and sealing design, existing equipment lacks efficient heat insulation components. When feeding and discharging, the heat inside the chamber is easily dissipated. Coupled with an unreasonable material channel design and a long opening time of the chamber door, the temperature stability inside the curing chamber is poor, which not only increases energy consumption but also results in insufficient temperature uniformity during the film material curing process, seriously affecting the consistency of the barrier and antibacterial properties of the product.

[0005] In view of this, we propose a curing equipment and method for high-barrier antibacterial plastic packaging films. Summary of the Invention

[0006] The purpose of the present invention is to provide a curing equipment and method for high-barrier antibacterial plastic packaging films. Through the cooperation of a handling mechanism, a heat insulation group, and a transportation device, the full-automatic transfer of high-barrier antibacterial plastic packaging film rolls inside and outside the curing chamber is realized, so as to solve the problems raised in the above background art.

[0007] To achieve the above purpose, on the one hand, the present invention provides the following technical solutions: A curing equipment for high-barrier antibacterial plastic packaging films, including a curing chamber and two transportation devices arranged on the inner walls at the front and rear ends of the curing chamber. Inside the curing chamber, a heat insulation group and a handling mechanism are provided near the right side opening of the chamber; The heat insulation group includes a heat insulation frame, and two discharge tracks and two feeding tracks are respectively arranged on the inner walls at the front and rear ends of the heat insulation frame; The handling mechanism includes a cylinder, a lifting plate driven by the cylinder, two material transporting parts arranged on the brackets at both ends of the lifting plate, two support plates, and two toothed plates arranged on the outer walls of the support plates; The material transporting part includes a lifting frame, a turning plate arranged on the top surface of the lifting frame, end teeth clamped at the bending part of the turning plate through a convex shaft, a convex plate arranged at the inner end of the lifting frame, a baffle plate arranged parallel to the convex plate, shaft teeth arranged at both ends of the bottom of the baffle plate, a frame-shaped toothed plate meshed with the two shaft teeth, and an electric push rod driving its movement; With the above settings, the material rolls into the top end of the lifting frame from the feeding track. After being blocked by the convex plate, the electric push rod drives the displacement of the frame-shaped toothed plate, and the meshed shaft teeth drive the baffle plate to rotate, so as to limit the material. After the material transporting part moves down with the lifting plate, the material falls onto the top of the transportation device and is conveyed into the curing bin by it. At the same time, the material transporting part can load the material and move it up to the outside of the discharge track. The end teeth are meshed with the toothed plate to rotate, driving the turning plate to rotate, and then the material falls into the discharge track and turns out.

[0008] In the technical solution of the present invention, the curing bin includes a bin body with openings at both the left and right ends, two bin doors rotatably connected to the bin openings at both ends of the bin body, and a support frame fixedly connected to the inner walls of the front and rear ends of the bin body by bolts.

[0009] With this setting, through the bin doors with openings at both ends, it is convenient for the operator to enter the curing bin to maintain the structure of the transportation device.

[0010] In the technical solution of the present invention, the transportation device includes two chain discs, a chain sleeved between the two chain discs, several groups of material transporting frames regularly distributed outside the chain, and an outer sleeve cover sleeved outside the chain. The chain discs are rotatably connected to the inside of the outer sleeve cover, and the outer sleeve cover is fixedly connected to the outer wall of the support frame by bolts.

[0011] With this setting, several groups of regularly distributed support frames convey the material rollers placed with high-barrier antibacterial plastic packaging films into the curing bin.

[0012] In the technical solution of the present invention, the heat insulation frame is clamped and fixed to the inner wall of the bin body. Two through slots for the material to pass through are opened on the left wall of the heat insulation frame, and the bottom surface of the discharge track is inclined with the left side higher than the right side, and the bottom surface of the feeding track is inclined with the left side lower than the right side. Heat insulation curtains are also clamped on the front and rear end frame walls of the heat insulation frame outside the through slots.

[0013] With this setting, through the design of the discharge track and the feeding track, the distance between the material roller and the bin opening of the bin body is lengthened, and the safety of the operator in transferring high-calorie plastic packaging films is improved.

[0014] In the technical solution of the present invention, the cylinder is fixedly connected to the inner bottom surface of the bin body by bolts, and the lifting plate is fixedly connected to the driving end of the cylinder by bolts.

[0015] The cylinder drives the lifting plate to move up and down, enabling several groups of material conveying parts to move synchronously.

[0016] In the technical solution of the present invention, the lifting frame is fixedly connected to the brackets at both ends of the lifting plate by bolts. A limiting slider is integrally formed on the outer wall of the lifting frame. An inner opening is provided inside the limiting slider on the left side. The right end of the flap tilts upward, a limiting hole is provided at the left end of the flap, and a plate surface groove for placing the frame-shaped tooth plate is provided on the top surface of the horizontal plate of the flap. A limiting part is provided inside the inner opening.

[0017] In the technical solution of the present invention, the convex plate is welded and fixed to the top end of the left end of the flap. The baffle is rotatably connected inside the plate surface groove. The shaft tooth is clamped and fixed to the convex shaft at the bottom end of the baffle. The frame-shaped tooth plate meshes with the shaft tooth and is clamped and fixed to the end of the driving rod of the electric push rod. The frame-shaped tooth plate, the shaft tooth, and the electric push rod are all arranged in the placement groove inside the flap.

[0018] This setting, during the process of the cylinder driving the lifting plate to move up and down, cooperates with the electric push rod to change the position of the baffle, thereby realizing the limitation and liberation of the material roller, and improving the material flow efficiency and operation safety in cooperation with the discharge rail and the feeding rail of the heat insulation frame.

[0019] In the technical solution of the present invention, the limiting part includes a sliding rod slidably connected to the inner opening of the inner opening of the inner opening, an outer convex block integrally formed at the end of the sliding rod and slidably connected to the outer opening of the inner opening, a square plate clamped and fixed to the outer wall of the outer convex block, and a spring sleeved on the outer side of the sliding rod. The elastic force provided by the spring pushes the outer convex block to move outward.

[0020] In the technical solution of the present invention, two support plates are clamped and fixed to the inner wall of the bin body. Two limiting chutes adapted to the size of the limiting sliders are provided on the inner walls of the support plates. A guiding groove for the movement of the end tooth convex shaft is provided on the groove wall of the limiting chute. An inner groove for the outer convex block to extend into is also provided on the inner wall of the support plate. The tooth plate is fixedly connected to the outer wall of the support plate by screws. The tooth plate is located above the upper part of the guiding groove close to the top.

[0021] With the above setting, the outer convex block in the limiting part extends into the inner groove under the action of the spring, causing the sliding rod to contract from the limiting hole, thereby releasing the limitation on the flap.

[0022] On the other hand, the present application also provides a curing method for a high-barrier antibacterial plastic packaging film. Using the above-mentioned high-barrier antibacterial plastic packaging film curing equipment, it includes the following steps: S1. First, control the air cylinder to drive the lifting plate to move upward, transport the end of the tipping flap in the material transporting part to below the inner opening of the feeding rail, and the operator drives the forklift to send both ends of the material roll placed with the high-barrier antibacterial plastic packaging film into the feeding rail; S2. Subsequently, the material roll rolls into the top of the lifting frame along the feeding rail. After the convex plate blocks it, the electric push rod drives the frame-shaped tooth plate to displace, and the meshing shaft teeth drive the baffle to rotate, thereby limiting the material roll; S3. Then, control the air cylinder to drive the lifting plate to move downward. After the material transporting part moves downward with the lifting plate, the material roll is dropped into the interior of a pair of material transporting frames in the transporting device. And the continuously descending lifting plate will make the end of the material roll separate from the convex plate and the baffle; S4. Start the external control system to drive the chain wheels in the two transporting devices to rotate synchronously, and drive a number of material transporting frames to displace through the chain, thereby transporting the material roll placed with the high-barrier antibacterial plastic packaging film into the curing chamber; S5. After that, after repeating the above operations to complete the placement of multiple groups of material rolls of the high-barrier antibacterial plastic packaging film, close the chamber door, start the heating device to raise the temperature inside the chamber body. After the curing of this batch of plastic packaging film is completed, open the chamber door at the right end of the chamber body; S6. Control the air cylinder to drive the lifting plate to rise. During this process, the outer convex block in the limiting part extends into the inner groove under the action of the spring, and the sliding rod contracts from the limiting hole, thereby releasing the limitation on the flap; S7. In addition, start the driving end of the electric push rod to contract, and make the frame-shaped tooth plate engage with the shaft teeth. After driving the baffle to rotate again, it contracts into the surface slot; S8. Subsequently, when the material transporting part moves to the outside of the discharging rail, the end teeth engage with the tooth plate and rotate, driving the flap to rotate, so that the end plate at the end of the flap is parallel to the opening of the discharging rail, and the material falls into the discharging rail and then is taken out by the operator; S9. After that, cooperate with the transporting device to transport the material roll towards the material transporting part. After repeating the above operations, multiple groups of material rolls of the plastic packaging film can be taken out of the curing chamber.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. This high-barrier antibacterial plastic packaging film curing equipment and its method realize the full-automatic transfer of the high-barrier antibacterial plastic packaging film coil inside and outside the curing chamber through the cooperation of the handling mechanism, heat insulation group and transporting device. When feeding, the material automatically rolls into the lifting frame through the inclined feeding rail, the electric push rod drives the baffle to limit and fix it, the air cylinder accurately places it to the material transporting frame, and it is sent into the heating area in the chamber by the chain. When discharging, the locking of the flap is automatically released during the lifting process, the end teeth engage with the tooth plate to make the flap flip, and the material slides out through the inclined discharging rail. The whole process does not require manual contact with high-temperature materials, avoiding handling risks, with tight process connection and precise actions, significantly improving the flow efficiency and operation safety of mass production.

[0024] 2. The aging equipment and method for the high-barrier antibacterial plastic packaging film. The equipment is provided with a heat insulation frame and a heat insulation curtain on the inner wall of the aging chamber. The heat insulation curtain at the material feeding trough effectively blocks the heat exchange during non-operation periods. The inclined design of the material feeding rail and the discharging rail enables the materials to quickly enter and exit, shortening the opening time of the chamber door. The handling mechanism operates near the heat insulation frame, reducing the heat dissipation of components, maintaining the stability of the high-temperature environment inside the chamber, and reducing the heat loss caused by frequent material feeding and discharging. While ensuring the temperature uniformity during the aging process of the high-barrier antibacterial film material, it significantly reduces energy consumption and ensures the consistency of product quality.

[0027] Please refer to Figures 1-3 As shown, the present embodiment provides a technical solution: The high-barrier antibacterial plastic packaging film curing equipment includes a curing chamber 100 and two sets of transportation devices 200 provided on the inner walls of the front and rear ends of the curing chamber 100. An insulation group 300 and a handling mechanism 400 are provided inside the curing chamber 100 near the right side opening. Specifically, the curing chamber 100 includes a chamber body 110 with openings at both left and right ends, two chamber doors 120 rotatably connected to the openings at both ends of the chamber body 110, and a support frame 130 fixedly connected to the inner walls of the front and rear ends of the chamber body 110 by bolts.

[0028] Furthermore, the chamber body 110 is used in cooperation with the chamber door 120 to ensure the sealing inside the curing chamber 100, and the support frame 130 is used to provide a fixed base point for the transportation device 200. This setting enables the operator to enter the curing chamber 100 through the chamber door 120 with openings at both ends to maintain the structure of the transportation device 200.

[0029] Please refer to Figures 1-4 As shown, in the present embodiment, the transportation device 200 includes two chain sprockets 210, a chain 220 sleeved between the two chain sprockets 210, several groups of material transporting frames 230 regularly distributed outside the chain 220, and an outer cover 240 sleeved outside the chain 220. The chain sprockets 210 are rotatably connected inside the outer cover 240, and the outer cover 240 is fixedly connected to the outer wall of the support frame 130 by bolts.

[0030] Furthermore, an electric system for driving the transportation device 200 is provided outside the storage body 110. After the chain 220 rotates, the chain 220 moves. This setting enables a number of regularly distributed support frames 130 to convey the material rollers on which the high-barrier antibacterial plastic packaging film is placed into the curing chamber 100.

[0031] Please refer to Figures 5-6 As shown, in this embodiment, the heat insulation group 300 includes a heat insulation frame 310. Two discharge rails 312 and feeding rails 313 are respectively formed on the inner walls at the front and rear ends of the heat insulation frame 310.

[0032] Specifically, the heat insulation frame 310 is snap-fitted and fixed to the inner wall of the storage body 110. Two material passing grooves 311 that penetrate left and right for materials to pass through are formed on the left wall of the heat insulation frame 310. The bottom surface of the discharge rail 312 is inclined with the left side higher than the right side, and the bottom surface of the feeding rail 313 is inclined with the left side lower than the right side. Heat insulation curtains 320 are also snap-fitted on the front and rear end frame walls of the heat insulation frame 310 outside the material passing grooves 311.

[0033] Furthermore, the heat insulation frame 310 cooperates with the heat insulation curtain 320 to prevent temperature leakage when a number of material rollers of the high-barrier antibacterial plastic packaging film are being transported. This setting, through the design of the discharge rail 312 and the feeding rail 313, lengthens the distance between the material roller and the opening of the storage body 110, improving the safety of the operator when transporting high-calorie plastic packaging film.

[0034] Please refer to Figures 7-11 As shown, in this embodiment, the handling mechanism 400 includes a cylinder 410, a lifting plate 420 driven by it, two sets of material transporting parts 430 arranged on the brackets at both ends of the lifting plate 420, two support plates 440, and two toothed plates 450 arranged on the outer walls of the support plates 440.

[0035] Specifically, the cylinder 410 is fixedly connected to the inner bottom surface of the storage body 110 through bolts, and the lifting plate 420 is fixedly connected to the driving end of the cylinder 410 through bolts.

[0036] Furthermore, the cylinder 410 drives the lifting plate 420 to move up and down, enabling a number of sets of material transporting parts 430 to move synchronously.

[0037] Please refer to Figures 7-13 As shown, in this embodiment, the material transporting part 430 includes a lifting frame 431, a turning plate 432 arranged on the top surface of the lifting frame 431, end teeth 433 snap-fitted to the bent part of the turning plate 432 through a convex shaft, a convex plate 434 arranged at the inner end of the lifting frame 431, a baffle plate 435 arranged parallel to the convex plate 434, shaft teeth 436 arranged at both ends of the bottom of the baffle plate 435, a frame-shaped toothed plate 438 meshing with the two shaft teeth 436, and an electric push rod 437 for driving its movement.

[0038] Specifically, the lifting frame 431 is fixedly connected to the brackets at both ends of the lifting plate 420 by bolts. A limiting slider 4310 is integrally formed on the outer wall of the lifting frame 431. An inner opening 4311 is provided inside the limiting slider 4310 on the left side. The right end of the flap 432 is upturned, a limiting hole 4320 is provided at the left end of the flap 432, a plate surface slot 4321 for placing the frame-shaped toothed plate 438 is provided on the top surface of the horizontal plate of the flap 432, and a limiting portion 439 is provided inside the inner opening 4311.

[0039] Further, the convex plate 434 is fixedly welded to the top end of the left end of the flap 432. The baffle 435 is rotatably connected inside the plate surface slot 4321. The shaft gear 436 is clamped and fixed to the convex shaft at the bottom end of the baffle 435. The frame-shaped toothed plate 438 meshes with the shaft gear 436 and is clamped and fixed to the end of the driving rod of the electric push rod 437. The frame-shaped toothed plate 438, the shaft gear 436, and the electric push rod 437 are all arranged in the placement groove inside the flap 432.

[0040] Further, two support plates 440 are clamped and fixed to the inner wall of the bin body 110. Two limiting chutes 441 adapted to the size of the limiting sliders 4310 are provided on the inner wall of the support plates 440. A guiding groove 442 for the convex shaft of the end tooth 433 to move is provided on the groove wall of the limiting chute 441. An inner groove 443 for the outer convex block 4391 to extend into is further provided on the inner wall of the support plates 440. The toothed plate 450 is fixedly connected to the outer wall of the support plates 440 by screws. The toothed plate 450 is located above the guiding groove 442 near the top.

[0041] Further, the material rolls into the top end of the lifting frame 431 from the feeding rail 313. After being blocked by the convex plate 434, the electric push rod 437 drives the frame-shaped toothed plate 438 to displace. The meshing shaft gear 436 drives the baffle 435 to rotate, thereby limiting the material. After the material transporting part 430 moves down with the lifting plate 420, the material falls onto the top of the transporting device 200 and is conveyed into the ripening bin 100 by it.

[0042] Further, the material transporting part 430 can load the material and move it up to the outside of the discharging rail 312. The end tooth 433 meshes with the toothed plate 450 and rotates, driving the flap 432 to rotate, so that the material falls into the discharging rail 312 and then turns out.

[0043] This setting realizes the limitation and liberation of the material roller by changing the position of the baffle 435 driven by the electric push rod 437 during the process of the cylinder 410 driving the lifting plate 420 to move up and down, and improves the material flow efficiency and operation safety in cooperation with the discharging rail 312 and the feeding rail 313 of the heat insulation frame 310.

[0044] Such as Figures 7-13As shown, in this embodiment, the limiting portion 439 includes a sliding rod 4390 slidably connected to the inner opening of the inner opening 4311, an outer protrusion 4391 integrally formed at the end of the sliding rod 4390 and slidably connected to the outer opening of the inner opening 4311, a square plate 4392 clipped and fixed on the outer wall of the outer protrusion 4391, and a spring 4393 sleeved on the outer side of the sliding rod 4390, and the elastic force provided by the spring 4393 pushes the outer protrusion 4391 to move outward.

[0045] Furthermore, under the action of the spring 4393, the outer protrusion 4391 in the limiting portion 439 extends to the inside of the inner groove 443, allowing the slide bar 4390 to retract from the limiting hole 4320, thereby releasing the restriction on the flap 432, and the square plate 4392 is used to limit the movement range of the slide bar 4390 in the inner opening 4311.

[0046] The present invention also provides a method for aging a high barrier antibacterial plastic packaging film, using the above-mentioned high barrier antibacterial plastic packaging film aging equipment, comprising the following steps: S1. First, the air cylinder 410 is controlled to drive the lifting plate 420 to move upward, and the raised end of the flap 432 in the material transporting part 430 is transported to the lower part of the inner opening of the feeding track 313. The operator drives a forklift to deliver the two ends of the material roll with the high barrier antibacterial plastic packaging film into the feeding track 313; S2. Subsequently, the material roller feeding rail 313 rolls into the top of the lifting frame 431. After the convex plate 434 blocks it, the electric push rod 437 drives the frame-shaped tooth plate 438 to move, and the meshing shaft teeth 436 drive the baffle plate 435 to rotate, thereby limiting the position of the material roller; S3, then, the air cylinder 410 is controlled to drive the lifting plate 420 to move downward, and the material transporting part 430 moves downward along with the lifting plate 420, and the material roll falls into the inside of a pair of material transporting racks 230 in the transport device 200, and the lifting plate 420 that continues to move downward will make the end of the material roll separate from the convex plate 434 and the baffle 435; S4, start the external control system to drive the chain disks 210 in the two groups of transport devices 200 to rotate synchronously, and drive the groups of material transport racks 230 to move through the chains 220, so as to transport the material rollers with the high barrier antibacterial plastic packaging film to the inside of the ripening warehouse 100; S5, after which the above operations are repeated to complete the placement of multiple groups of high barrier antibacterial plastic packaging films on the material rolls, after closing the warehouse door 120, the heating device is started to heat the interior of the warehouse body 110, and after the ripening of this batch of plastic packaging films is completed, the warehouse door 120 at the right end of the warehouse body 110 is opened; S6. Control the air cylinder 410 to drive the lifting plate 420 to rise. During this process, the convex block 4391 in the limiting part 439 extends into the inner groove 443 under the action of the spring 4393, and the slide rod 4390 contracts from the limiting hole 4320, thereby releasing the limitation on the flap 432; S7. In addition, start the driving end of the electric push rod 437 to contract, so that the frame-shaped toothed plate 438 meshes with the shaft gear 436. After driving the baffle 435 to rotate again, it contracts into the inner part of the plate surface slot 4321; S8. Subsequently, when the material conveying part 430 moves to the outside of the discharge rail 312, the end teeth 433 mesh with the toothed plate 450 and rotate, driving the flap 432 to rotate, so that the end plate at the end of the flap 432 is parallel to the opening of the discharge rail 312, and the material falls into the discharge rail 312 and then is taken out by the operator; S9. After that, cooperate with the conveying device 200 to convey the material roller in the direction of the material conveying part 430. After repeating the above operations, the material rollers of multiple groups of plastic packaging films can be taken out from the aging bin 100.
