Description

Technical Field

[0001] The invention relates to the technical field of plastic molding, in particular to a vacuum forming production system. Background Art

[0002] Blister packaging is a plastic molding process. The main principle is to heat and soften the flat plastic hard plate, then use vacuum to absorb it on the mold surface, and then cool it to form it. It is widely used in plastic packaging, lighting, large shells, advertising, automotive plastic interior parts, decoration and other industries. The main advantages of blister packaging are: saving raw and auxiliary materials, light weight, convenient transportation, good sealing performance, meeting the requirements of environmentally friendly green packaging, and can include any special-shaped products. No additional cushioning materials are required for packing; the packaged products are transparent and visible, beautiful in appearance, easy to sell, and suitable for mechanized and automated packaging, which is convenient for modern management, saving manpower and improving efficiency.

[0003] The production process of plastic panels is divided into two steps: extrusion and blistering, which are carried out separately. However, the extruder often has a faster extrusion rate, while the blistering step requires the plastic sheet to be cooled before heating, softening, adsorbing, cooling, etc. Relatively speaking, the rate is relatively slow, and the material extruded by the extruder often needs to be placed aside to cool, waiting for the blistering step to slowly proceed.

[0041] The invention provides a vacuum forming production system.

[0042] In the embodiment of the present invention, Figures 1 to 6 As shown, the blister molding production system includes an extruder 10 , a laminating device 20 , a cutting device 30 , a plurality of blister machines 40 , and a conveying device 50 .

[0043] Specifically, the extruder 10 is used to extrude molten polymer, the feed side of the laminating device 20 is arranged corresponding to the discharge port of the extruder 10, so as to extrude and mold the molten polymer extruded by the extruder 10, and the feed side of the cutting device 30 is arranged corresponding to the discharge side of the laminating device 20, and is used to cut the billet extruded and molded by the laminating device 20, wherein the specific cutting length of the billet can be set according to the actual product.

[0044] A plurality of blister machines 40 are arranged along a first direction, and the blister machines 40 are used for blister molding the cut blanks.

[0045] The conveying device 50 is arranged at the outlet side corresponding to the cutting device 30, and is used to receive the blanks cut by the cutting device 30 and then convey the blanks. The conveying device 50 includes a plurality of conveying mechanisms 51 and a plurality of material dividing mechanisms 52. The plurality of conveying mechanisms 51 or the plurality of material dividing mechanisms 52 correspond to the plurality of blister machines 40 one by one. The plurality of conveying mechanisms 51 are arranged at intervals from each other along the first direction. One of the conveying mechanisms 51 is arranged at the outlet side corresponding to the cutting device 30, and is used to receive the blanks cut by the cutting device 30 and then convey them. A material dividing mechanism 52 is provided between two adjacent conveying mechanisms 51. In other words, the plurality of conveying mechanisms 51 and the plurality of material dividing mechanisms 52 are arranged alternately in sequence in the first direction. There are at least two conveying mechanisms 51, and similarly, there are at least two material dividing mechanisms 52.

[0046] Among them, each material distribution mechanism 52 includes a mounting bracket 521, a first material distribution component 522 and a second material distribution component 523. The first material distribution component 522 and the second material distribution component 523 can be installed on the mounting bracket 521 in a liftable manner, and the first material distribution component 522 and the second material distribution component 523 are arranged with an upper and lower interval. The material distribution mechanism 52 has a first position and a second position located above the first position. In the first position, the first material distribution component 522 is connected to the conveying mechanism 51 on the downstream side. In the second position, the first material distribution component 522 is connected to the vacuum forming machine 40, and the second material distribution component 523 is connected to the conveying structure on the downstream side.

[0047] Specifically, in the actual production process of plastic panels, after receiving the blanks cut by the cutting device 30, the conveying mechanism 51 conveys the blanks to the material dividing mechanism 52 on the downstream side. After receiving the blanks, the material dividing mechanism 52 can choose to move upward to the second position to convey the received blanks to the blister machine 40 at the corresponding position for blister molding. When the first material dividing component 522 moves upward to the second position, the blanks can be conveyed by the second material dividing component 523, and the blanks are conveyed to the material dividing mechanism 52 on the downstream side for material dividing. In this way, there is no need to place the cut blanks next to the blister machine 40 and wait for the blister molding step.

[0048] This arrangement enables the extruder to discharge materials uninterruptedly, because the extruded blanks can be distributed to multiple blister machines through multiple material distribution mechanisms. For example, when the first blister machine is cooling the plastic plate, the second blister machine performs the blister operation. After the plastic plate on the first blister machine is cooled, the plastic plate on the second blister machine is cooled. In this way, multiple material distribution mechanisms and blister machines can circulate and transport the blanks to the blister machines at different times for blister molding, thereby improving the production and preparation efficiency of plastic plates. At the same time, there is no need to manually carry the plastic plates in the entire conveying project, which is conducive to reducing labor costs. Of course, after receiving the blanks, the material distribution mechanism 52 can also choose to transport the blanks to the conveying mechanism 51 on the downstream side.

[0049] In this embodiment, the conveying mechanism is a high temperature resistant conveyor belt. We know that the board blank extruded by the extruder is in a high temperature state. The present application conveys the board blank through a high temperature resistant conveyor belt, and does not need to be transported by a manipulator by grabbing. This will not cause scratches on the board blank, resulting in an unsightly product after production and affecting the appearance. The board blank is transported to the blister machine in a rolling manner by the conveyor belt for molding, so that no marks are left on the high temperature board blank during the transportation process, making the product more beautiful after production. Among them, the conveying mechanism is not limited to the conveyor belt. In other embodiments, the conveying mechanism can be a tank chain or a conveyor roller.

[0050] It is worth noting that the plastic sheet sent to the blister machine 40 has the temperature required for the blister process because it has not been cooled and waited for. In other words, the plastic sheet does not need to be heated again and can be directly blister processed, which can reduce electricity costs.

[0051] In addition, we know that repeated heating of plastics will accelerate aging and affect the service life. In the present application, the plastic panels do not need to be heated for a second time and can be directly subjected to the blister process, so that the produced plastic panels have a longer service life and higher strength. Moreover, since the plastic panels do not need to be heated for a second time, the gas emission during the subsequent heating process of the plastic panels is avoided, which is beneficial to environmental protection.

[0052] Specifically, in some embodiments, after receiving the blank, the first material distribution component 522 can immediately move upward to the second position to transport the blank to the blister machine 40 for blister molding, and the second material distribution component 523 receives the blank on the upstream side and transports it to the downstream conveying mechanism 51. When the first material distribution component 522 moves upward to the second position, the blank can be transported by the second material distribution component 523 to the downstream material distribution mechanism 52 for distribution. In this way, there is no need to place the cut blank next to the blister machine 40 and wait for the blister molding step.

[0053] In another embodiment, after the material dividing mechanism 52 receives the blank, the first material dividing component 522 conveys the blank to the conveying mechanism 51 on the downstream side, and the conveying mechanism 51 on the downstream side conveys the blank to the downstream side, until the first material dividing component 522 on the most downstream material dividing mechanism 52 receives the blank, and then no longer continues to convey the blank to the downstream side, but moves upward to the second position to convey the blank to the blister machine 40 at the corresponding position for blister molding. In other words, the cut blank is first conveyed to the blister machine 40 on the downstream side.

[0054] In this embodiment, after the material distribution mechanism 52 receives the blank, the first material distribution component 522 transports the blank to the downstream conveying mechanism 51. This is because when the first material distribution component 522 moves upward to the second position, the conveying mechanism 51 needs to stop conveying, and transporting the blank to the downstream side first can reduce the waiting time for the material distribution mechanism 52 to move up and down, which is conducive to improving the production efficiency of plastic panels.

[0055] The number of the blister machines 40 can be set according to the speed of the extruder, the laminating device 20, and the cutting device 30. When the speed of the extruder, the laminating device 20, and the cutting device 30 is fast, more blister machines 40 need to be set. On the contrary, when the speed of the extruder, the laminating device 20, and the cutting device 30 is slow, fewer blister machines 40 can be set. This application does not impose specific restrictions on this.

[0056] In summary, it can be seen that the blister molding production system of the technical solution of the present invention is achieved by setting the conveying device 50 corresponding to the outlet side of the cutting device 30. The conveying device 50 includes a plurality of conveying mechanisms 51 and a plurality of dividing mechanisms 52. The plurality of conveying mechanisms 51 are arranged in a first direction with intervals between them, and a dividing mechanism 52 is provided between two adjacent conveying mechanisms 51. The dividing mechanisms 52 include a mounting bracket 521, a first dividing component 522 and a second dividing component 523. The first dividing component 522 and the second dividing component 523 can be mounted on the mounting bracket 521 in a liftable manner and are spaced apart up and down. The dividing mechanism 52 has a first position and a second position located above the first position. In the first position, the first dividing component 522 is connected to the conveying mechanism 51 on the downstream side. In the second position, the first dividing component 522 is connected to the blister machine 40, and the second dividing component 523 is connected to the conveying structure on the downstream side. In this way, after receiving the blank, the material distribution mechanism 52 can move upward to the second position, so that the first material distribution component 522 receives the blank and delivers it to the blister machine 40 at the corresponding position for blister molding. When the first material distribution component 522 moves upward to the second position, the blank can be transported by the second material distribution component 523, and the blank has been delivered to the material distribution mechanism 52 on the downstream side for material distribution, and the received blank is distributed to the blister machine 40 at the corresponding position for blister molding by the material distribution mechanism 52 on the downstream side. In this way, there is no need to place the cut blank next to the blister machine 40 and wait for the blister step slowly. It can be seen that compared with the current blister production device, the blister molding production system of the technical solution of the present application has high production efficiency of plastic panels, does not require staff to carry blanks, and realizes the automation of integrated molding of plastic panels. Moreover, the plastic panels sent to the blister machine have the temperature required for the blister process because they have not been cooled and waited, that is, the plastic panels do not need to be heated again and can be directly blistered, which can reduce electricity costs. In addition, since the plastic panels do not need to be heated again, they can be directly treated by vacuum forming, which makes the plastic panels have a longer service life and higher strength. At the same time, since the plastic panels do not need to be heated again, the gas emission in the subsequent heating process of the plastic panels is avoided, which is beneficial to environmental protection.

[0057] In some embodiments, the mounting bracket 521 includes two first support frames 5211, a second support frame 5212 and a mounting seat 5213, the two first support frames 5211 are arranged opposite to each other, the second support frame 5212 is connected between the two first support frames 5211 and is located at the top of the two first support frames 5211, the mounting seat 5213 is movably installed between the two first support frames 5211, and has a first mounting portion and a second mounting portion arranged at intervals up and down, the first material distribution component 522 and the second material distribution component 523 are respectively installed on the first mounting portion and the second mounting portion; the material distribution mechanism 52 also includes a lifting component 524; the lifting component 524 is connected to the mounting seat 5213, and is used to drive the mounting portion to rise and fall. That is, by driving the mounting seat 5213 to rise and fall through the lifting component 524, the first material distribution component 522 and the second material distribution component 523 can be driven to rise and fall, so that the structural design of the material distribution mechanism 52 can be reduced, and the overall structural complexity of the material distribution mechanism 52 is reduced.

[0058] Further, the lifting assembly 524 includes a driving motor 5241, a speed reducer 5242, two gears and two racks; the driving motor 5241 is installed on the second support frame 5212, the speed reducer 5242 is connected to the output shaft of the driving motor 5241, two transmission shafts are respectively arranged at both ends of the speed reducer 5242, two gears are respectively sleeved on the two transmission shafts, two racks are respectively arranged on the opposite sides of the mounting seat 5213, and extend in the direction of the second support frame 5212, a rack is arranged corresponding to a gear, and meshes with the corresponding gear. That is, the motor drives the mounting seat 5213 to rise and fall through the gear rack. As we know, the gear rack transmission has good stability. When applied to this solution, it can make the lifting of the mounting seat 5213 more stable. Of course, in other embodiments, the lifting assembly 524 is set as a cylinder, the cylinder is installed on the second support frame 5212, and the telescopic end of the cylinder is connected to the mounting seat 5213.

[0059] In some embodiments, the conveying mechanism 51 also includes a first conveying component 511 and a second conveying component 512, and the second conveying component 512 and the second conveying component 512 are arranged with an interval up and down, the first conveying component 511 conveys along a first direction, and the second conveying component 512 conveys along a second direction, the first direction and the second direction are perpendicular to each other, the second conveying component 512 is connected to the vacuum forming machine 40, and in the second position, the second material dividing component 523 is connected to the second conveying component 512.

[0060] That is, when the first material distribution component 522 moves upward to the second position, the received blank can be conveyed to the second conveying part, and the second conveying component 512 conveys the blank to the blister machine 40 at the corresponding position for blister molding. Of course, in other embodiments, when the first material distribution component 522 is located at the second position, the received blank is directly conveyed to the blister machine 40 at the corresponding position for blister molding.

[0061] In some embodiments, the first support frame 5211 is hollowed out, and at least one of the two first support frames 5211 is provided with an inspection door 60. Specifically, when the material dispensing mechanism 52 needs to be inspected, the inspection door 60 can be opened to perform the inspection work, which is helpful to reduce the difficulty of inspection. Among them, at least one of the two first support frames 5211 is provided with an inspection door 60, or both first support frames 5211 are provided with inspection doors. Of course, in other embodiments, the first support frame 5211 may not be provided with an inspection door 60.

[0062] In some embodiments, the blister molding system further includes a conveying mechanism 70, which includes two mounting sections 71 and multiple groups of conveying rollers 72. The two mounting sections 71 are connected between the laminating device 20 and the cutting device 30, and are spaced apart from each other. Multiple groups of conveying rollers 72 are disposed between the two mounting sections 71, and two adjacent groups of conveying rollers 72 are spaced apart. Specifically, after the laminating device 20 presses the extruded material, the blank is in a high temperature state. By setting the conveying mechanism 70 as multiple groups of spaced apart conveying rollers 72, when conveying the pressed blank, the heat dissipation efficiency can be effectively improved, and the conveying stability can also be ensured. Of course, in other embodiments, the conveying structure is configured as a conveyor belt.

[0063] In some embodiments, the laminating mechanism includes a mounting frame 21, a trigger roller, a sensor, a sewing machine and a laminating assembly 24; the mounting frame 21 is provided with a sewing position and a material discharge position spaced apart and located above the sewing position, the material discharge position is provided with a first material discharge roller 22 and a second material discharge roller 23, and the sewing position has a sewing table;

[0064] The trigger roller is arranged between the stitching position and the unloading position, and is movably mounted on the mounting frame 21 in the up-down direction. The lower side of the trigger roller forms a feeding area. The trigger roller has a feeding position and a trigger position located below the feeding position. When the material belt released by the first unloading roller 22 passes through the feeding area in a tensioned state, the trigger roller is lifted to the feeding position. When the tail section of the material belt on the first unloading roller 22 falls off, the trigger roller moves to the trigger position and presses the tail section of the material belt released by the first unloading roller 22 onto the stitching table. The sensor is arranged on the mounting frame 21, and the sensor is triggered when the trigger roller is at the trigger position.

[0066] The laminating assembly 24 has a laminating channel, and the discharge port of the extruder 10 is arranged toward the entrance side of the laminating channel, which is used to deliver the extrudate to the laminating channel. The material belt on the first discharge roller 22 or the second discharge roller 23 passes through the feeding area on the lower side of its trigger roller and is guided to the entrance side of the laminating channel so as to enter the laminating channel together with the extrudate of the extruder 10 for laminating.

[0067] Specifically, when the tail section of the tape unwound by the first unwinding roller 22 falls from the first unwinding roller, the trigger roller falls from the feeding position to the trigger position under the action of gravity, thereby triggering the sensor, and the tail section of the tape falls onto the sewing table. Subsequently, the second unwinding roller 23 starts unwinding, and when the first section of the unwound tape is delivered to the sewing table and overlaps with the tail section of the tape delivered by the first unwinding roller 22, the overlapped tapes can be sewn by the sewing machine, thereby sewing and connecting the two rolls of tape. The sewn tape is gradually tightened under the action of traction, and in the tensioned state, the sewn tape can lift the trigger roller at the trigger position to the feeding position, so that the unwinding can continue. In this way, after the material tape on the first unwinding roller 22 is unwound, the material tape placed in advance on the second unwinding roller 23 can be used to continue unwinding, which can shorten the time for taking and placing the material tape roll. In addition, the setting of the trigger roller can automatically press the material tape on the table when unwinding to the tail section. After the sewing machine sews the tail section of the material tape unwound by the first unwinding roller 22 and the first section of the material tape unwound by the second unwinding roller 23, under the action of tension, the trigger roller is lifted to the feeding position through the material tape to realize the automatic resetting of the trigger roller, which is convenient for the next use. In this way, the two rolls of material tape can be sewn and connected in a shorter time, thereby improving the efficiency of connecting the material tapes.

[0068] In some embodiments, the first unloading roller 22 and the second unloading roller 23 are installed in parallel at the unloading position, a unloading space is formed between the first unloading roller 22 and the second unloading roller 23, and the trigger roller is located below the unloading space.

[0069] Specifically, the first unwinding roller 22 and the second unwinding roller 23 both unwind the material strip to the lower side of the trigger roller through the unwinding space, which can reduce the unwinding path of the material strip and the structural setting of the laminating device 20, thereby reducing the overall structural complexity of the laminating device 20 and improving production efficiency. Of course, in other embodiments, the first unwinding roller and the second unwinding roller unwind from opposite sides of the mounting frame 21 respectively.

[0070] In some embodiments, when the trigger roller is at the trigger position, the stitching machine is located at the upstream side of the trigger roller. Specifically, when the trigger roller falls from the feeding position to the trigger position, under the action of gravity, the trigger roller can pull the tail section of the material strip directly onto the stitching table, so that there is no need to set up other mechanisms to pull the tail section of the material strip, thereby simplifying the overall structure of the laminating device 20 and reducing the overall structural complexity of the laminating device 20. Of course, in other embodiments, when the trigger stick is at the trigger position, the stitching machine is located at the downstream side of the trigger roller.

[0071] In some embodiments, the first unwinding roller 22 and the second unwinding roller 23 are both driven by motors. When the sensor is triggered and the first preset condition is reached, the motor of the second unwinding roller 23 is turned on until the second preset condition is reached, so that the first section of the material tape released by the second unwinding roller 23 is stacked on the tail section of the material tape released by the first unwinding roller 22, and then the first section of the material tape released by the second unwinding roller 23 is sewn with the tail section of the material tape released by the first unwinding roller 22 by a sewing machine.

[0072] Specifically, the sensor is electrically connected to the motors of the first unloading roller 22 and the second unloading roller 23. When the tail section of the material belt released by the first unloading roller 22 falls from the first unloading roller 22, the trigger roller will fall from the feeding position to the trigger position. At this time, the control device of the blister molding production system will drive the material belt to be transported for another section according to the setting of the first preset condition, until the tail section of the material belt is transported to the sewing table, and the control device controls the second unloading roller 23 to start according to the second preset condition. The unwinding operation is started to be carried out, so that the first section of the material tape delivered by the second unwinding roller 23 is delivered to the sewing table and stacked with the tail section of the material tape delivered by the first unwinding roller 22, and then the second unwinding roller 23 is controlled to stop delivering, and the sewing machine is controlled to sew the tail section of the material tape delivered by the first unwinding roller 22 and the first section of the material tape delivered by the second unwinding roller 23. Then, the control device controls the second unwinding roller 23 to start the unwinding operation, and the sewn material tape is gradually tensioned, and the trigger roller is lifted to the feeding position under the tensioning force.

[0073] Among them, the first preset condition and the second preset condition can be set to the unwinding time of the material strip unwound by the first unwinding roller 22 and the second unwinding roller 23, or set to the number of unwinding rotations of the first unwinding roller 22 and the second unwinding roller 23, which can be set specifically according to actual conditions.
