Description

Technical Field

[0001] The invention relates to the technical field of blister forming equipment, in particular to blister forming equipment and a blister forming process for a wine bottle holder. Background Art

[0002] Thermoforming is a plastic processing technology widely used in packaging, medical, food and other fields. As an efficient and economical plastic processing method, thermoforming technology has always occupied an important position in the packaging field since its industrial application in the 1950s. Especially in wine packaging, thermoforming wine bottle holders have become the preferred solution for high-end wine transportation and terminal display due to their advantages such as light weight, strong impact resistance and high degree of customization. As the high-end trend of the global wine consumption market intensifies, consumers' requirements for packaging quality have been upgraded from basic protection functions to comprehensive demands that emphasize both aesthetic performance and functionality, which poses higher challenges to the thermoforming process: on the one hand, the wine bottle holder needs to adapt to the special-shaped bottle body within millimeter-level accuracy to ensure zero displacement during transportation; on the other hand, its surface finish and anti-static performance are directly related to the brand image. For example, when luxury wines are displayed, dust adsorbed by static electricity will cause visual defects.

[0003] Common defects in plastic parts include micro cracks (<0.1mm), local thickness deviation (±0.05mm), incomplete voids, etc., especially in plastic parts made of recycled plastics.

[0023] As introduced in the background technology, in order to solve the deficiencies existing in the prior art and the above technical problems, the present application proposes a blister forming device and a blister forming process for a wine bottle holder.

[0024] Embodiment 1:

Under the pressing of the pressing and conveying units 22, when the upper molding mechanism 3 and the lower molding mechanism 4 are separated, the molded coil can be separated from the upper molding mechanism 3 and the lower molding mechanism 4 respectively; the output guiding unit 23 sends the molded coil into the cutting mechanism 5, and the whole page of plastic parts cut by the cutting mechanism 5 falls into the stacking mechanism 6 for stacking and collection and then output.

[0026] When in use, the whole roll of raw material is installed inside the coil unwinding mechanism 1, and the coil unwinding mechanism 1 unwinds and unwinds the raw material roll; first, the free end of the raw material roll needs to be guided to pass through the feed guide unit 21, the pressing and conveying unit 22 and the output guide unit 23 in sequence; the coil moves under the joint drive of the feed guide unit 21, the pressing and conveying unit 22, the output guide unit 23 and the coil unwinding mechanism 1; after the static electricity carried by the coil is removed by the static elimination mechanism 7, the coil is input between the upper forming mechanism 3 and the lower forming mechanism 4, and is input between the upper forming mechanism 3 and the lower forming mechanism 4.

[0027] Embodiment 2:

[0028] See also Figure 1-Figure 9The difference from the above embodiment is that a damage detection mechanism 8 is arranged above the feed guide unit 21 and at the front end of the electrostatic elimination mechanism 7, the damage detection mechanism 8 includes a plurality of hoisting detection curtains 81, the feed guide unit 21 includes a plurality of feed guide rollers 211 and a plurality of powered guide rollers 212; each powered guide roller 212 is respectively arranged under each hoisting detection curtain 81, and a plurality of detection probes 811 are arranged at the bottom end of each hoisting detection curtain 81, and the detection probes 811 of two adjacent hoisting detection curtains 81 are staggered.

[0029] The surface of each powered guide roller 212 is energized, and when the coil passes through each powered guide roller 212, the powered guide roller 212 and each detection probe 811 can be isolated; when a damaged coil passes through the powered guide roller 212, the damaged position of the coil can conduct electricity between the powered guide roller 212 and at least one detection probe 811, and the damaged position and damaged area of ​​the coil can be determined based on the position and number of the conductive detection probes 811.

[0030] The static elimination mechanism 7 includes a plurality of elimination roller groups 71, each of which includes a plurality of elimination rollers 711 respectively arranged on both sides of the coil, and each elimination roller 711 is grounded; under the guidance of each feed guide roller 211, when the coil passes through the elimination roller 711, the electric charge it carries can be eliminated through the grounding of each elimination roller 711.

[0031] A pretreatment mechanism 9 is also provided at one end of the feed guide unit 21 close to the lower forming mechanism 4, and the pretreatment mechanism 9 includes a plurality of heating rollers 91, an injector 92 and an interception frame 93; a heating element is provided inside each heating roller 91, and the injector 92 is provided inside the interception frame 93, and the spraying range of the injector 92 is smaller than the range of the interception frame 93; when the coil passes through the heating roller 91, it can be preheated by the heating roller 91, and the range of the interception frame 93 perpendicular to the moving direction of the coil is smaller than the width of the coil, and the injector 92 can spray oil on the coil passing through the range of the interception frame 93.

[0032] When in use, by setting each detection probe 811 of the damage detection mechanism 8, it is possible to detect whether each detection probe 811 is in a conductive state, so that when the coil passes through each energized guide roller 212, the energized guide roller 212 and each detection probe 811 can be isolated; when the damaged coil passes through the energized guide roller 212, the damaged position of the coil can conduct the energized guide roller 212 and at least one detection probe 811, and the damaged position and damaged area of ​​the coil can be determined according to the position and number of the conductive detection probes 811; thereby, a reminder can be given during output, so that it is convenient to find possible damaged plastic parts directly according to the production interval of the production line in the later stage, which can effectively save the time of finding damaged plastic parts and thus ensure the molding quality of the produced plastic parts.

[0033] In particular, when used, each detection probe 811 does not directly contact the coil, and due to the material of the coil, the coil has insulation. When the energized guide roller 212 and the corresponding detection probes 811 are energized, a high-voltage electric field exists between the energized guide roller 212 and the corresponding detection probes 811. When the coil is not damaged, although the electric field exists, there is no conduction between the energized guide roller 212 and the corresponding detection probes 811, and no current is generated inside the detection probe 811; if the coil is damaged, the high-voltage electric field breaks through the air (tip discharge), and a current is generated inside the detection probe 811 corresponding to the damaged position, and the current detection probe 811 can output an alarm signal (the detection process can refer to the method for inspecting airtight sealed packaging in Chinese patent CN1206522C); At this time, the control terminal set up inside the equipment can receive the alarm signal output by the detection probe 811, and directly locate the coordinates of the defect position on the coil at this time (usually the length of the coil is used as the y-axis, and the width of the coil is used as the x-axis), so as to locate the entire page of plastic parts where the defect position is located (the defect position only affects the plastic parts themselves and will not interfere with the blister molding process of the plastic parts). When the entire page of plastic parts is transported to the inside of the cutting mechanism 5 (the moving coordinates of the defect position in the entire blister molding device are determined by converting the time according to the speed of the entire blister molding device transporting the coil), a buzzer and flash alarm are used to call the police. The staff is called, and the machine is stopped when the cutting gate 52 has finished cutting the whole page of plastic parts but has not fallen from the blanking plate 53, so that the staff can re-check and confirm the whole page of plastic parts. At this time, the control terminal adds the downtime time to the conveying time of the coil to accurately complete the subsequent inspection process, and the damage detection mechanism 8 is only used to detect the damage of the coil, and is not aimed at detecting the product quality of individual plastic parts after molding, cutting and separation (the product quality of individual plastic parts is affected by factors other than coil defects, and other defects are mostly defects in the cutting process, which are not related to the inspection of the whole page of plastic parts).

[0034] After the above-mentioned damage detection mechanism 8 is powered on for detection, through the setting of the static elimination mechanism 7, each elimination roller 711 on both sides of the coil is grounded, and under the guidance of each feed guide roller 211, the coil can eliminate the electric charge it carries through the grounding of each elimination roller 711 when passing through the elimination roller 711, which can effectively eliminate the static electricity carried in the coil itself, and can also eliminate the static electricity introduced by the power-on detection of the damage detection mechanism 8, effectively avoiding the interference of static electricity on the subsequent forming process; through the setting of the pretreatment mechanism 9, the coil can be preheated by the heating roller 91 when passing through the heating roller 91, and the range of the interception frame 93 perpendicular to the moving direction of the coil is smaller than the width of the coil, and the injector 92 can spray oil on the coil passing through the range of the interception frame 93, and can effectively pre-treat the coil before forming, while ensuring the forming rate of the coil, avoiding the adhesion between the collected plastic parts through oil spraying.

[0035] Furthermore, in actual use, the heating roller 91 can be replaced by a heating plate (see Figure 4-Figure 5 Replacement), during the process of the upper molding mechanism 3 and the lower molding mechanism 4 performing blister molding on the coil, a partial area of ​​the coil that is about to be blister molded can be preheated by the heating plate, and this partial area can be exactly in the position where the upper molding mechanism 3 and the lower molding mechanism 4 are aligned during the subsequent transportation, and the heating time for this partial area is the same as the blister molding time of the upper molding mechanism 3 and the lower molding mechanism 4.

[0036] Embodiment three:

[0037] See also Figure 1-Figure 9 , which is different from the above-mentioned embodiment, is that the upper molding mechanism 3 comprises an upper molding frame 31, an upper mold-closing cylinder 32, an upper mold 33 and an upper negative pressure machine 34, and the lower molding mechanism 4 comprises a lower molding frame 41, a lower mold-closing cylinder 42, a lower mold 43 and a lower blower 44; the upper mold-closing cylinder 32 can drive the upper mold 33 to approach the lower mold 43, and the lower mold-closing cylinder 42 can drive the lower mold 43 to approach the upper mold 33; heating elements are arranged inside the upper mold 33 and the lower mold 43, and after the upper mold 33 and the lower mold 43 are closed, the coil is closed between the upper mold 33 and the lower mold 43 under the cooperation of the negative pressure provided by the upper negative pressure machine 34 and the lower blower 44.

[0038] The pressing and conveying unit 22 includes two pressing and conveying frames 221, and the two pressing and conveying frames 221 are respectively arranged on both sides of the lower forming mechanism 4; a plurality of upper pressing rollers 222 and a plurality of lower pressing rollers 223 are arranged inside the pressing and conveying frames 221, each of the upper pressing rollers 222 is in contact with the upper surface of the passing coil, and each of the lower pressing rollers 223 is in contact with the lower surface of the passing coil, and each of the upper pressing rollers 222 and each of the lower pressing rollers 223 can rotate freely; each of the upper pressing rollers 222 and each of the lower pressing rollers 223 can jointly limit the position of the formed coil and separate the formed coil from the upper mold 33 and the lower mold 43.

[0039] Specifically, when in use, a cooling mechanism (preferably a cooling fan in this embodiment) is also provided on the outside of the upper forming mechanism 3. After separation between the upper mold 33 and the lower mold 43, the formed coil is cooled by the cooling mechanism.

[0040] When in use, through the setting of the pressing and conveying unit 22, the two ends of the coil can be respectively located inside the two pressing and conveying frames 221, and the upper pressing rollers 222 and the lower pressing rollers 223 can jointly limit the position of the coil to prevent the movement of the coil during the forming process, and can also effectively guide the coil during movement, effectively ensuring that the area formed each time is at the same position of the width of the coil, so that the coil is heated by the heating elements provided inside the upper mold 33 and the lower mold 43. After the upper mold 33 and the lower mold 43 are closed, the negative pressure provided by the upper negative pressure machine 34 and the cooperation of the lower blower 44 provide a higher forming force, and the coil is closed in the upper mold 33 and the lower mold 43, effectively ensuring the forming effect of the coil.

[0041] The output guide unit 23 includes a plurality of output guide rollers 231, the cutting mechanism 5 includes a cutting frame 51, a cutting knife 52 is arranged on the side of the cutting frame 51 close to the lower forming mechanism 4, and two blanking plates 53 are arranged on the side of the cutting frame 51 away from the lower forming mechanism 4, and a blanking motor 54 is arranged on one side of the two blanking plates 53; the stacking mechanism 6 includes a stacking guide frame 61 and a stacking carrying plate trolley 62, stacking guide rods 611 are arranged on both sides of the stacking guide frame 61, and the setting position of the stacking guide rods 611 avoids the rotation range of the blanking plates 53.

[0042] The cutting blade 52 can cut the formed coil into a whole page of plastic parts, which can fall to the top of the two closed blanking plates 53; driven by the blanking motor 54, the two blanking plates 53 rotate and open to the side close to the stacking mechanism 6, and the whole page of plastic parts falls on the surface of the stacking carrying pallet 62 under the guidance of the two blanking plates 53 and the stacking guide rods 611 on both sides; the stacking carrying pallet 62 can be moved out from the space between the stacking guide rods 611 on both sides.

[0043] Therefore, when in use, the entire page of plastic parts is stably dropped onto the surface of the stacking carrier cart 62 through the guidance of the two blanking plates 53 to the open position after being rotated and opened under the drive of the blanking motor 54, and through the guidance of the stacking guide rods 611, and the falling position of each entire page of plastic parts is the same under the guidance, so that they can be effectively stacked on the surface of the stacking carrier cart 62, thereby improving the efficiency of collecting the entire page of plastic parts.
