Description

Technical Field

[0001] The invention relates to the technical field of blister equipment, in particular to a continuous blister tooling for an infrared blister machine. Background Art

[0002] The blister process is widely used in packaging, decoration and other industries. The infrared blister machine uses the infrared heating principle to heat and soften the plastic sheet, and then fits it to the mold through vacuum adsorption or air pressure molding to form the desired shape.

[0003] According to the Chinese patent publication number CN220784844U, the patent provides a forming and positioning tooling for a blister packaging box, including a frame, a fixed frame is fixedly installed on both sides of the frame, an input roller body and an output roller body are respectively arranged inside the fixed frames on the left and right sides, a conveying motor is installed on one side of the fixed frame, a forming groove is arranged above the middle position of the frame, a clamping and positioning structure for forming a blister packaging box is arranged inside the forming groove, a forming cylinder is fixedly installed on the top of the frame, and a forming mold is connected below the forming cylinder. A forming and positioning tooling for a blister packaging box is provided. When the forming and positioning tooling is used, the threaded rod is driven to rotate by rotating the adjusting hand wheel, and the positioning plate on the front side is driven to move horizontally, and then the positioning plate is used to clamp the forming mold, and the vacuum adsorption head below is driven to move downward by the upper forming cylinder, and the material in the mold is vacuum-formed by the vacuum pump. In the process of vacuum forming, the alignment effect between the infrared transmitting module and the infrared receiving module can be used to position the vacuum adsorption head and the mold to avoid deviation during the forming process.

[0004] However, when the blister machine uses infrared to heat the plastic sheet to soften it, the center of the plastic sheet will stretch and sag due to softening, resulting in uneven thickness of the sheet, which affects the subsequent adsorption effect. In addition, when unloading, the cooling efficiency of the clamping part is lower than that of the middle area, which easily causes the edge of the plastic sheet to stick to the clamp, making unloading inconvenient. Therefore, a continuous blister tooling for an infrared blister machine is proposed to solve the above problems. Summary of the invention

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a continuous blister tooling for an infrared blister machine, which has the following beneficial effects:

[0020] 1. The infrared blister machine uses a continuous blister tooling, and the anti-collapse plate of the anti-collapse part is connected with the screw thread through a slider. During the heating process, as the chassis moves, the rack drives the gear to rotate, causing the screw to rotate, thereby driving the anti-collapse plates to slide close to each other and merge, and lift the suspended part of the plastic sheet. This avoids the softened plastic sheet from stretching and collapsing due to gravity, improves the plasticity and stability of the plastic sheet during subsequent blistering, ensures the uniform thickness of the blister product, and improves product quality. The control unit realizes automatic control of the heating unit and the anti-collapse unit and other components through the cooperation of rotating rods, gears, screws, transmission belts and other components. During the heating process, the chassis moves and drives the rack to rotate the gear, and then controls the movement of the anti-collapse plate through the transmission belt. The entire process does not require excessive human intervention, thereby improving production efficiency and control accuracy.

[0021] 2. The infrared blister machine uses a continuous blister tooling, and the bottom array of the chassis of the heating part is installed with infrared heating tubes, and the rack is symmetrically arranged with the rack as the center line. This symmetrical arrangement can effectively improve the uniform heating effect of the plastic sheet. When the chassis moves, the rack fixed in the middle of the bottom engages with the gear to drive the gear to rotate, and then the screw is rotated through the transmission belt to realize the movement of the chassis, ensuring that the infrared heating tube heats the plastic sheet evenly. After the filament inside the heating tube is energized and heated, infrared rays are radiated outward to heat the plastic sheet according to the blackbody radiation law. The heating temperature can be accurately controlled to make the plastic sheet reach an ideal softening state, providing good conditions for subsequent blister molding.

[0022] 3. The infrared blister machine uses a continuous blister tooling, which adopts a temperature sensor and a linear motor to be electrically connected. When the temperature sensor senses that the temperature of the plastic sheet has risen to a certain temperature, it can prompt the linear motor to drive the chassis to reset, and at the same time control the action of the anti-collapse plate, thereby realizing the automatic linkage between the heating and anti-collapse processes, ensuring the stability and efficiency of the blister process. The air extracted by the pump is collected through the air collecting sleeve and re-sprayed onto the upper surface of the plastic sheet through the air outlet pipe, which accelerates the cooling of the plastic sheet in conjunction with the blister operation. Compared with the natural cooling of the plastic sheet exposed to the air in the traditional technology, this method further improves the cooling efficiency, shortens the molding time, provides a guarantee for continuous operation, and improves the processing efficiency.

[0023] 4. The infrared blister machine uses a continuous blister tooling, which adopts the stripping plate of the anti-sticking part to realize automatic flipping under the action of the paddle plate on the special-shaped block of the clamping frame of the clamping part through the cooperation of the spring and the spring. When the clamping frame is opened, the paddle plate pushes the spring plate to flip and ejects the formed plastic sheet, which is convenient for rapid unloading of the plastic sheet and will not stick to the pad. Moreover, when the clamping frame is closed, the position design of the paddle plate makes it not affect the clamping of the plastic sheet by the clamping frame. The operation is simple and the degree of automation is high, which improves the unloading efficiency and reduces the manpower burden.

[0024] 5. The infrared blister machine uses a continuous blister tooling, which adopts a clamping frame that is rotatably connected between the two support blocks of the clamping part. The frame edges of the clamping frame are aligned with the pad and the anti-collapse plate respectively. The opening and closing of the clamping frame can be easily operated by the grip rod to stably clamp the plastic sheet. During the entire blister process, including heating, anti-collapse, blister forming and other processes, the stable clamping ensures the fixed position of the plastic sheet, which helps to improve the quality of blister. At the same time, the cooperation between the clamping frame and the anti-sticking part makes the loading and unloading operations before and after blistering smoother, thereby improving the efficiency of continuous processing.

[0039] In the present invention, in order to enable the blister tooling of this case to be freely loaded and unloaded on the blister machine base 1, the mounting part 2 of this case includes a negative pressure chamber 21, and the vacuum pressure in the blister is uniformly maintained in a labyrinth manner. The negative pressure chamber 21 is opened at the top of the blister machine base 1, and electric push rods 22 are installed at the four corners of the inner wall of the negative pressure chamber 21. The mold is pushed by the lifting of the electric push rods 22. Pads 23 are installed on both sides of the outer side of the cavity of the negative pressure chamber 21. The pads 23 are used for placing plastic sheets. The blister machine base 1 is provided with wheel holes 24. The blister machine Rod holes 25 are provided on both sides of the base 1, and the two rod holes 25 are connected to the wheel holes 24. A pump 26 is installed at the back angle of the base 1 of the blister machine. The model of the pump 26 can refer to the HP-0300V oil-free silent vacuum pump. The pump 26 is connected to the negative pressure chamber 21. When the pump 26 works, negative pressure suction is generated in the negative pressure chamber 21 to perform blistering on the plastic sheet. A cover 27 is installed on the top rear side of the blister machine base 1. The cover 27 is used to store the heating device. The top of the cover 27 is provided with an organic hole 28, and the inner wall of the machine hole 28 A linear motor is installed, and a blister mold 9 is arranged at the inner rod end of the four electric push rods 22. The mold is arranged with vents for uniform blister negative pressure. The blister mold 9 is attached to the inner wall of the negative pressure chamber 21. A control console 10 is installed on the front side of the blister machine base 1. A control panel is installed on the control console 10. The control panel is used to control the electric push rods 22, pumps 26, linear motors, temperature sensors 53 and infrared heating tubes 74 in this case to achieve automated work and real-time data feedback. In order to improve resource utilization and make full use of air flow, The utilization part 3 of this case includes a pipe sleeve 31, which is installed at the rear end bottom of the blister machine base 1, and pipe sleeves 32 are installed on both sides of the outer wall of the cover 27. The inner wall of the pipe sleeve 31 is installed with an air collecting sleeve 33, the sleeve opening of which covers the air outlet of the pump 26, and air outlet pipes 34 are installed on both sides of the air collecting sleeve 33. The two air outlet pipes 34 are fixedly passed through the two pipe sleeves 32 and extend to the top of the negative pressure chamber 21. The air collecting sleeve 33 is used to collect the extracted air, and the air is blown back to the plastic sheet along the air outlet pipe 34 to accelerate cooling.

[0040] In this embodiment, in order to improve the automation capability of the blister operation, the control unit 4 of this case includes a rotating rod 41, which is rotatably connected to the inner wall of the wheel hole 24, and the two ends of the rotating rod 41 are respectively movable through the two rod holes 25 and extend to the outside of the blister machine base 1. The inner wall of the wheel hole 24 is provided with a gear 42, and the gear 42 is fixedly sleeved on the outer wall of the rotating rod 41. Both sides of the blister machine base 1 are fixedly connected with L-shaped frames 43, and the two L-shaped frames 43 are rotatably connected with screws 44. The ends of the two screws 44 and the two extended ends of the rotating rod 41 are fixedly sleeved with pulleys, and the pulleys on each screw 44 and the pulleys on the same side of the rotating rod 41 are transmission-connected with a transmission belt 45. In order to improve the uniform heating effect of the surface energy of the plastic sheet, the heating unit 7 of this case includes two connecting pieces 71, and the two connecting pieces The sheet 71 is fixedly connected to the top front side of the blister machine base 1, and sliding rods 72 are fixedly connected between the two connecting sheets 71 and the inner wall of the cover 27. The two sliding rods 72 are slidably connected to a chassis 73. The bottom array of the chassis 73 is installed with infrared heating tubes 74. The filaments inside these heating tubes will generate heat after being powered on, and the temperature will rise. According to the black body radiation law, when the temperature of an object rises, it will radiate energy outward, including infrared rays, thereby heating the plastic sheet. A rack 75 is fixedly connected to the middle of the bottom of the chassis 73. The infrared heating tubes 74 are symmetrically arranged with the rack 75 as the midline. The symmetrically arranged infrared heating tubes 74 can effectively improve the uniform heating effect of the plastic sheet. The rack 75 is meshed with the gear 42, and the gear 42 is synchronously driven to rotate by the rack 75 following the movement of the chassis 73.

[0041] It is worth noting that in order to prevent the center of the plastic sheet from stretching and sagging due to softening due to heating, resulting in uneven sheet thickness, the anti-collapse part 5 of this case includes an anti-collapse plate 51, which is slidably connected between the ends of the two pads 23, and the bottom of the anti-collapse plate 51 is in contact with the top of the blister machine base 1, and the top of the anti-collapse plate 51 is flush with the top surface of the pad 23, which is conducive to the smooth loading of the plastic sheet. A slider 52 is fixedly connected to one side of the bottom of the anti-collapse plate 51, and the slider 52 is threadedly sleeved on the screw 44 on the same side. A temperature sensor 53 is embedded on the top surface of the anti-collapse plate 51. The model of the temperature sensor 53 can refer to the SA1XL surface thermocouple. The temperature sensor 53 is electrically connected to the linear motor, and the linear motor drives the chassis 73 to reset to the cover 27 by sensing that the plastic sheet has heated up to a certain temperature. A groove 54 is provided on the top surface of one end of the anti-collapse plate 51 close to the negative pressure chamber 21, and a limiting rod 55 is fixedly connected between the inner walls of the groove 54. In order to automatically separate the plastic sheet and the clamp when unloading, the anti-sticking part 6 in this case includes a stripping plate 61, which is attached to the inner wall of the groove 54, and one end of the stripping plate 61 is rotatably sleeved on the limiting rod 55. A sliding groove 62 is provided at the other end of the stripping plate 61, and a spring 63 is slidably connected to the inner wall of the sliding groove 62. A spring 64 is elastically connected between the spring 63 and the inner wall of the sliding groove 62. There are two anti-collapse parts 5 and anti-sticking parts 6 respectively, and the other anti-collapse part 5 and anti-sticking part 6 are installed on the screw 44 on the other side of the blister machine base 1 and between the other ends of the two pads 23. The two anti-collapse parts 5 and anti-sticking parts 6 are symmetrically arranged, and the two anti-collapse plates 51 can be merged with each other.

[0042] It is worth mentioning that in order to ensure the stability and flatness of the plastic sheet clamping, the clamping part 8 in this case includes two support blocks 81, and the two support blocks 81 are symmetrically installed on the top of the blister machine base 1. A clamping frame 82 is rotatably connected between the two support blocks 81. The frame edges of the clamping frame 82 are aligned with the two pads 23 and the two anti-collapse plates 51 respectively. A grip rod 83 is installed on the front of the outer wall of the clamping frame 82, and the clamping frame 82 can be opened or pressed down by the grip rod 83. Special-shaped blocks 84 are fixedly connected on both sides of the outer wall of the clamping frame 82, and the ends of the two special-shaped blocks 84 are rotatably connected with a paddle 85, and the top of each paddle 85 is respectively fitted with the bottom of the spring piece 63 on the same side.

[0043] Working principle: in this case, the top surface of the anti-collapse plate 51 is flat and smooth and is provided with an anti-stick coating, which can prevent the plastic sheet from sticking to the anti-collapse plate 51 after being heated and softened. The clamping frame 82 is flipped and lifted by the grip rod 83, so that the paddle plate 85 on the special-shaped block 84 pushes the spring piece 63 to rise, and drives the stripping plate 61 to flip upward with the limit rod 55 as the axis, thereby ejecting the plastic sheet on the pad 23, thereby facilitating the rapid unloading of the formed plastic sheet without sticking to the pad 23. Due to the different axial positions of the clamping frame 82 and the stripping plate 61, after the clamping frame 82 is flipped upward by a certain angle, the paddle plate 85 will separate from the spring piece 63. At this time, the stripping plate 61 loses the drag force and falls into the groove 54 to reset. The plastic sheet is added to the pad 23 again and the clamping frame 82 is pressed down. The paddle plate 85 contacts the spring piece 63 from above to produce a flip without getting stuck, which can ensure that the clamping frame 82 stably presses the plastic sheet on the pad 23 and the anti-collapse plate 51.

[0044] The machine hole 28 in the present case can be provided with a linear motor so that the mover end of the linear motor is connected to the chassis 73 to realize the effect of automatically conveying the chassis 73. The chassis 73 can also be manually pushed and pulled to transport the chassis 73 along the slide bar 72. The operation has a high degree of freedom and can be changed at any time according to the use requirements. The linear motor is turned on through the control panel to drive the chassis 73 to move out of the cover 27. The infrared heating tube 74 is powered on to heat up and shines on the top of the plastic sheet to heat it, causing the plastic sheet to soften. At the same time, the rack 75 moves with the chassis 73 and drives the gear 42 to rotate, thereby driving the pulley to rotate synchronously through the rotating rod 41. Under the linkage of the transmission belt 45, the screws 44 on both sides rotate synchronously and drive their respective sliders 52 to slide, thereby causing the anti-collapse plates 51 on both sides to slide close to each other and merge, and then the suspended part of the plastic sheet is lifted to avoid the stretching and collapse of the softened plastic sheet, thereby improving the plasticity and stability of the plastic sheet during subsequent blistering.

[0045] At the same time, when the anti-collapse plates 51 are close to each other and assembled, the spring piece 63 will be squeezed by the pad 23 and thus retracted into the inner wall of the slide groove 62. At this time, the spring piece 63 is away from the dial plate 85, and the dial plate 85 is not blocked and flips over and resets again. When the anti-collapse plates 51 are away from each other again, the spring piece 63 is pushed out of the slide groove 62 by the elastic force of the spring 64 and returns to the top of the dial plate 85, so that when the clamping frame 82 is opened later, the spring piece 63 can drive the material return plate 61 to flip over again. The whole process is automatically reset without human intervention, which is convenient to operate and simplifies the method of use, avoids the problem of one-sided damage and residual heat caused by repeated fingering of the plastic sheet by human labor, and improves the efficiency and safety of material unloading.

[0046] The temperature sensor 53 contacts the softened plastic sheet to detect temperature changes in real time. When the set temperature value is reached, the temperature sensor 53 turns off the infrared heating tube 74 through an electrical signal and resets the linear motor, thereby driving the chassis 73 to reset and enter the cover 27. At the same time, the rack 75 drives the gear 42 to reverse, causing the two anti-collapse plates 51 to move away from each other and open the negative pressure chamber 21. The electric push rod 22 pushes the blister mold 9 to rise and fit the softened plastic sheet, and then the pump 26 is used to draw a vacuum to complete the blister operation. Compared with the traditional technology, in this case, after the plastic sheet is heated and softened, while waiting for the blister mold 9, there will be no problem of long center collapse time, which will lead to uneven thickness of the plastic sheet, reduced deformation, or even loss of plasticity. After the anti-collapse plates 51 are separated from each other for a while, the blister work can be carried out directly, which greatly avoids the problem of softening and stretching of the plastic sheet and improves the quality of product molding.

[0047] During vacuuming, air enters the air collecting sleeve 33 and is re-sprayed onto the upper surface of the plastic sheet along the air outlet pipe 34, which accelerates the cooling of the plastic sheet in cooperation with the blister operation. Compared with the natural cooling of the plastic sheet exposed to the air under the traditional technology, this case further improves the cooling efficiency and shortens the molding time, thereby improving the processing efficiency for continuous operation. After the blister is completed, the clamping frame 82 is opened by the grip rod 83, and the spring piece 63 is continued to be pushed by the dial plate 85, so as to flip the ejection plate 61 to eject the molded plastic sheet, simplifying the operation, reducing the manpower burden, and reducing the pressure of continuous operation.
