Description

Technical Field

[0001] The invention relates to the field of container production, in particular to a blow molding device and a method for manufacturing a cosmetic bottle using the blow molding device. Background Art

[0002] In the packaging field, blow molding technology is used to produce various plastic bottles, cosmetic bottles and other containers. The basic principle of blow molding technology is to heat the plastic raw materials to a molten state, and then form the molten plastic in a mold by blowing. During the blow molding process, the plastic raw materials gradually fit the inner wall of the mold under the action of the blowing pressure, and finally form the desired plastic products. However, due to the instability of the contact between the blowing pressure and the inner wall of the mold, direct blowing will cause irregular convex spots to form on the outer surface of the mold.

[0003] Therefore, the existing production process usually extends additional raised space on the basis of the shaping mold, thereby introducing gas into the raised space to reduce the impact with the inner wall of the mold, and then the raised part is cut off and sent out for secondary hot melt molding. However, when the existing blow molding device is performing the cutting and sending process, residues will be retained on the cross section of the mold, and the mold is easily offset during the sending process, thereby affecting the subsequent secondary hot melt process. Summary of the invention

[0010] By adopting the above technical solution, the air pressure pipe is connected to the external air pressure generating device, so as to transmit air pressure to make the air pressure clamp perform a clamping action, thereby providing power for grasping the bottle body mold.

[0011] Preferably, a sliding groove is provided downwardly at the top of the connecting crossbeam, and a guide block is protrudingly provided at the position of the sliding groove on the lower end surface of the movable seat, and the guide block is movably plugged into the sliding groove.

[0012] By adopting the above technical solution, the guide block is movably inserted in the slide groove. When the moving seat moves along the guide rod, the guide block moves in the slide groove, thereby improving the stability of both ends of the moving seat.

[0013] Preferably, a discharge trough is provided in the middle of the surface of the main body base, a plurality of support plates are fixedly provided on the inner wall of the discharge trough, slide rails are fixedly provided on both sides of the top of the plurality of support plates, and both slide rails are connected to an external driving device.

[0016] By adopting the above technical solution, the tray moves along the slide rail, thereby driving multiple bottle molds to move, and at the same time the bottle molds and multiple pneumatic clamps remain aligned, so that the pneumatic clamps can descend to grab and displace the bottle molds.

[0017] Preferably, a stabilizing plate is fixedly provided on the other side of the fixing plate relative to the fixture workpiece, and both sides of the lower end surface of the stabilizing plate are fixedly connected to the supporting columns.

[0020] By adopting the above technical solution, the installation frame connects the fan body and the fixing plate, thereby maintaining the overall stability of the fan body. At the same time, the installation frame can be movably disassembled, and then the fan body can be disassembled for easy replacement and maintenance.

[0021] Preferably, a movable groove is provided on the other side of the main body base relative to the discharge chute, a conveying belt is arranged in the movable groove, and the conveying belt is connected to an external rotating device. The surface of the main body base is protrudingly provided with extended baffles on both sides of the discharge chute, and the tops of the two extended baffles are flush with the bottle body mold placed on the surface of the tray.

[0022] By adopting the above technical solution, the movable groove is opened to reserve a fixed space for the installation of the conveyor belt. The surface of the conveyor belt is used to place the bottle mold transported by the pneumatic clamp and transport the processed bottle mold to the next process. At the same time, two extended baffles protrude from the surface of the main base to cover the pallet in the unloading chute. At the same time, the bottle mold on the surface of the pallet is flush with the top of the extended baffle, thereby preventing external debris from contacting the bottle mold.

[0023] A method for manufacturing a cosmetic bottle by a blow molding device, used for the above-mentioned blow molding device, comprises the following steps: S01. After the bottle mold is initially shaped, it is fixed on the surface of the pallet. The two slide rails drive the pallet to move horizontally. When the pallet passes under the fan body, the fan body runs to blow air downward to reduce the surface temperature of the bottle mold.

[0024] S02. As the pallet continues to move, when the pallet drives the bottle body mold to be located under the fixture workpiece and is aligned with the center points of the two pinch-off pliers, the first electric push rod drives the disassembly plate to move downward, and the disassembly plate drives the two fixture workpieces to descend. When the protrusion of the pinch-off pliers on the bottle body mold breaks, the two pinch-off pliers pinch off the protrusion, and then the first electric push rod drives the fixture workpiece to disengage the two pinch-off pliers.

[0025] S03. When the bottle body mold is clamped off by the clamping pliers, the air delivery seat transmits high-temperature airflow, so that the universal bamboo tube blows air to the cross section of the bottle body mold after clamping off, so that the high-temperature airflow is blown downward from the fracture surface of the bottle body mold to form a smooth treatment.

[0026] S04. The slide rail drives the pallet to move to the bottom of the pneumatic clamp, and the second electric push rod drives the connecting block to descend, and the connecting block drives the two lower pressure plates to descend synchronously. When the clamping end at the bottom of the pneumatic clamp is located on the surface of the bottle mold, the pneumatic tube transmits air pressure to make the pneumatic clamp clamp the bottle mold, and then the second electric push rod contracts to make the bottle mold separate from the pallet, and move from the moving seat to the top of the conveyor track to place the bottle mold.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects: 1. Use the tray to drive the bottle mold to move to the bottom of the fixture workpiece, so that the clamping pliers can clamp and cut off the protrusion of the bottle mold, and then the universal bamboo tube transmits high-temperature airflow to contact the surface of the bottle mold, so that the surface of the bottle mold is smooth. At the same time, the gas blows off the residue on the cross section of the bottle mold to avoid the residue on the surface of the bottle mold affecting the subsequent secondary hot melt process. At the same time, the surface of the cut end of the cosmetic bottle is smoother without burrs; 2. The bottle mold is plugged into the protruding fixed points on the surface of the tray to keep the bottle mold fixed when the tray moves. The soft pad covered on the clamping end of the pneumatic clamp improves the friction. The pneumatic clamp is then moved by the moving seat to shift the bottle mold to prevent the bottle mold from shifting during the movement, thereby eliminating the subsequent secondary hot melt positioning process for the bottle mold and improving production efficiency.

At the same time, the upper end surface of the disassembly plate 53 is located between the fixture workpieces 51. The position of the gas supply seat 58 is fixedly provided. The gas supply seat 58 is connected to the external airflow generating equipment, and the two sides of the upper end surface of the gas supply seat 58 are respectively connected with universal bamboo tubes 59. The two universal bamboo tubes 59 extend along the two fixture workpieces 51 respectively, and the distance between the nozzles of the two universal bamboo tubes 59 and the tray 9 is greater than the distance between the two clamping pliers 57 and the bottle body mold 10.

[0034] Reference Figure 2 , Figure 3 , Figure 8 , the difference between this embodiment and embodiment 1 is that a method for manufacturing a cosmetic bottle by a blow molding device includes a connecting beam 3 fixed to the upper end surfaces of two rows of support columns 2 by screws, the upper end surfaces of the two connecting beams 3 are both provided with grooves downward, two guide rods 4 are fixed between the two connecting beams 3, and mounting plates are fixed at both ends of the two guide rods 4, and the two mounting plates are fixed to the two connecting beams 3 by screws, and the shifting mechanism 6 includes a moving seat 61 arranged to move laterally along the surface of the guide rod 4, one end of the side surface of the moving seat 61 is connected to an external linear driving mechanism, and guide blocks 67 are protruding from the positions of the grooves on both sides of the lower end surface of the moving seat 61, and the two guide blocks 67 are engaged with the two grooves; A second electric push rod 62 is fixedly provided on the lower end surface of the movable seat 61, and the telescopic end of the second electric push rod 62 extends downward, and auxiliary support rods are fixedly provided on both sides of the telescopic end of the second electric push rod 62, and a connecting block 63 is fixedly provided at the end of the telescopic end of the second electric push rod 62, and lower pressure plates 64 are fixedly connected to both sides of the lower end surface of the connecting block 63, and through holes are opened at the positions of the two auxiliary support rods in the connecting block 63, and the two through holes respectively penetrate the bottom of the two lower pressure plates 64, and the two through holes are movably connected to the two auxiliary support rods, and multiple pneumatic clamps 65 (the number of pneumatic clamps 65 is at least four) are threadedly fixed on the surface of the two lower pressure plates 64, and the air connecting ends of the multiple pneumatic clamps 65 are located on the upper end surface of the lower pressure plate 64, and the clamping ends of the multiple pneumatic clamps 65 protrude from the lower end surface of the lower pressure plate 64.

[0035] It should be noted that the clamping end surfaces of the multiple pneumatic clamps 65 are wrapped with soft pads to increase friction, the air connecting ends of the multiple pneumatic clamps 65 are sealed and connected to the pneumatic tubes 66, and the connecting points between the multiple pneumatic tubes 66 are covered with sealing joints to maintain sealing and connectivity.

[0036] The two connecting beams 3 are fixedly connected to the support columns 2, thereby forming a fixation with the main base 1. The two guide rods 4 are connected to the two connecting beams 3 through the mounting plates on both sides, forming a fixed connection between the guide rods 4 and the main base 1, and the two guide rods 4 are movably plugged in at both sides of the movable seat 61, so that the movable seat 61 can move laterally while maintaining the balance of the movable seat 61 during movement. The movable seat 61 drives the second electric push rod 62 to move, and the telescopic end of the second electric push rod 62 extends to move the connecting block 63 downward. The connecting block 63 drives the two lower pressure plates 64 downward to make the pneumatic clamp 65 contact with the mold surface, and the external air pressure is transmitted by the pneumatic tube 66 to tighten the clamping ends at the bottom of the pneumatic clamp 65 toward each other, thereby clamping the mold.

[0037] Reference Figure 4 , Figure 5 , Figure 6 A discharge groove 7 is opened inwardly at the middle of the upper end surface of the main body base 1, and a plurality of support plates 12 are transversely fixed on the inner wall of the discharge groove 7, and slide rails 8 are fixed on both sides of the upper end surfaces of the plurality of support plates 12, and one end of the slide rail 8 extends to dock with an external driving device to maintain transmission, and a tray 9 is movably connected in the two slide rails 8, and a cylindrical fixed point is fixed on the upper end surface of the tray 9, and a plurality of convex points are arranged around the outer surface of the fixed point to increase friction, and a bottle body mold 10 is placed on the outer surface of each fixed point (the number of the bottle body mold 10 is the same as the number of the pneumatic clamp 65); Four horizontal plates extend laterally from one side of the fixing plate 14 close to the tray 9, and the ends of the four horizontal plates are located above the two shorter support columns 2, and the lower end surfaces of the four horizontal plates are fixed with stabilizing plates 13 by screws, and the lower end surfaces of the stabilizing plates 13 are also fixed to the two shorter support columns 2 by screws, and multiple mounting frames 16 are screwed between each of the four horizontal plates, and fan bodies 15 are arranged around the outer surfaces of the two rows of mounting frames 16, and the wiring terminals of the fan bodies 15 are connected to an external power supply device through a circuit, and the air outlets of the two rows of fan bodies 15 are longitudinally aligned with the bottle body mold 10.

[0038] It should be noted that a movable groove 17 is opened inwardly on the other side of the main body base 1 relative to the discharge chute 7, and a conveying crawler 18 is rotatably arranged in the movable groove 17. The rotating shaft of the conveying crawler 18 is connected to the external rotating device through a coupling, and the conveying crawler 18 is kept centrally aligned with the tray 9. At the same time, the upper end surface of the main body base 1 is located on both sides of the discharge chute 7 and protrudes with extended baffles 11. The height of the extended baffle 11 is consistent with the height of the top of the placed bottle body mold 10, thereby shielding and protecting the structure in the discharge chute 7.

[0039] The unloading chute 7 is provided with a reserved installation space for fixing multiple support plates 12 and the slide rail 8. The slide rail 8 is docked with an external driving device, thereby driving the tray 9 to move along the track of the slide rail 8. As the tray 9 moves, multiple bottle molds 10 are driven to move synchronously, thereby moving the bottle molds 10 to below the pinch-off clamp 57, the universal bamboo tube 59 and the pneumatic clamp 65 respectively. At the same time, when the bottle mold 10 moves to below the pinch-off clamp 57, multiple fan bodies 15 rotate to generate wind force, thereby blowing air to the bottle mold 10, reducing the overall temperature of the bottle mold 10 and increasing the hardness, which is convenient for pinching by the pinch-off clamp 57 and preventing external debris from adhering to the surface of the bottle mold 10 during the feeding process.

[0040] Among them, the device also includes a clamp workpiece 51, a first electric push rod 54, a universal bamboo tube 59, a second electric push rod 62, a pneumatic clamp 65, a fan body 15 and a conveyor belt 18, which are all existing technologies and their structural principles will not be repeated. At the same time, the driving device docked with the slide rail 8, the rotating device docked with the conveyor belt 18, the air pressure generating device connected to the air pressure pipe 66, and the air flow generating device connected to the air supply seat 58 are not the main technologies and will not be described in detail.

[0041] Example 2, reference Figures 1 to 8 , a method for manufacturing a cosmetic bottle by a blow molding device, comprising the following steps: S01. After the bottle body mold 10 is initially shaped, the bottle mouth is inserted into the fixed point on the surface of the tray 9 to form a horizontal fixation, and then the two slide rails 8 are operated to make the tray 9 translate along the track of the slide rails 8. When the tray 9 moves to the bottom of the fan body 15, the fan blades inside the fan body 15 rotate to generate wind force, thereby blowing air downward to contact the surface of the bottle body mold 10, thereby reducing the overall temperature of the bottle body mold 10 and increasing the hardness, which is convenient for the subsequent pinching process.

[0042] S02. After the bottle body mold 10 is cooled down, the tray 9 continues to translate. When the tray 9 moves to the bottom of the fixture workpiece 51, the bottle body mold 10 is aligned with the center point of the two pinch-off pliers 57. The first electric push rod 54 extends to drive the disassembly plate 53 to move downward. At this time, the two fixture workpieces 51 are connected to the disassembly plate 53 and descend synchronously. When the pinch-off pliers 57 break the preset protrusion of the bottle body mold 10, the circuit tube 52 transmits electricity to control the two pinch-off pliers 57 to rotate towards each other to pinch off the protrusion. Then the first electric push rod 54 is retracted upward to drive the disassembly plate 53 to rise, so that the two pinch-off pliers 57 are separated from the bottle body mold 10 as a whole.

[0043] S03. When the pinch-off pliers 57 pinch off the second group of bottle body molds 10, the air delivery seat 58 transmits high-temperature airflow to make the universal bamboo tube 59 blow air to the bottle body mold 10 that has completed the pinch-off operation, so that the high-temperature airflow is blown downward from the fracture surface of the bottle body mold 10, contacts with the surface of the bottle body mold 10 to generate high temperature, and cooperates with the wind force to deform the surface of the bottle body mold 10 to improve the smoothness.

[0044] S04. After the bottle body mold 10 is completely clamped and cut, the slide rail 8 drives the tray 9 to move to the bottom of the pneumatic clamp 65, and the center of the bottle body mold 10 is aligned with the center of the clamping end of the pneumatic clamp 65, and the second electric push rod 62 is extended, thereby driving the connecting block 63 to descend, and the two lower pressure plates 64 fixed to the connecting block 63 are synchronously descended. When the clamping end of the bottom of the pneumatic clamp 65 is located in the middle of the surface of the bottle body mold 10, the pneumatic tube 66 transmits air pressure to cause the clamping end of the pneumatic clamp 65 to contract, thereby clamping the bottle body mold 10, and then the second electric push rod 62 contracts, driving the clamped bottle body mold 10 to move upward out of the range of the tray 9, and move from the moving seat 61 to above the conveying crawler 18, and then cooperate with the descent of the second electric push rod 62 and the relaxation of the second electric push rod 62, thereby completing the displacement and placement process of the bottle body mold 10.

[0045] The implementation principle of Example 2 is as follows: after the bottle body mold 10 is initially shaped, the driving device drives the two slide rails 8 to run, and the two slide rails 8 run to make the tray 9 move along the track of the slide rails 8. At this time, the bottle body mold 10 is plugged into the fixed point on the surface of the tray 9, and the movement of the tray 9 drives the bottle body mold 10 to move horizontally. When the tray 9 moves to the bottom of the fan body 15, the external power supply device is energized to make the fan blades in the fan body 15 rotate, thereby blowing air downward to reduce the surface temperature of the bottle body mold 10; As the tray 9 continues to move, when the tray 9 moves to the bottom of the fixture workpiece 51 and the protrusion of the bottle body mold 10 is located between the pinch-off pliers 57, the slide rail 8 stops running, and the telescopic end of the first electric push rod 54 extends (the extension distance is set with a fixed value, and no personnel control pause is required), driving the disassembly plate 53 to move downward, and the disassembly plate 53 drives the two fixture workpieces 51 to descend. When the bottom of the pinch-off pliers 57 completely covers the protrusion of the bottle body mold 10, the circuit tube 52 transmits electricity to control the fixture workpiece 51, so that the pinch-off pliers 57 pinches off the protrusion, and then the telescopic end of the first electric push rod 54 contracts, and the slide rail 8 moves according to the set fixed parameter distance (the distance parameter is adjusted according to the actual situation), so that the next group of bottle body molds 10 are located below the pinch-off pliers 57, and the first electric push rod 54 repeats the decline, and then the pinch-off operation is performed; When the pinch-off pliers 57 process the next group of bottle body molds 10, the air delivery seat 58 transmits high-temperature airflow, so that the universal bamboo tube 59 blows air to the previous group of bottle body molds 10 that have been pinched off, so that the high-temperature airflow is blown downward from the fracture surface of the bottle body mold 10, so that the outer surface of the bottle body mold 10 is smoothed and the residue on the cross section is blown off; After the cross section of the bottle body mold 10 is completed, the slide rail 8 drives the tray 9 to move to the position directly below the pneumatic clamp 65, and the telescopic end of the second electric push rod 62 is extended to drive the connecting block 63 to descend, and the connecting block 63 drives the two lower pressure plates 64 to descend synchronously. When the clamping end at the bottom of the pneumatic clamp 65 is located in the middle of the surface of the bottle body mold 10, the air pressure generating device transmits air pressure through the air pressure pipe 66, so that the clamping end of the pneumatic clamp 65 clamps the bottle body mold 10, and then with the contraction of the telescopic end of the second electric push rod 62, the bottle body mold 10 is separated from the surface of the tray 9, and the driving device drives the moving seat 61 to move to the top of the conveyor belt 18 for descending and relaxing operations. Finally, the conveyor belt 18 sends the bottle body mold 10 to the next process for secondary hot melt molding.

[0046] Example 3, reference Fig. 9 , Fig.10A blow molding device comprises a sealing cylinder 19 which is surrounded by a sleeve on the outer surface of the nozzle end of a universal bamboo joint tube 59, a telescopic sleeve 20 is fixedly arranged on the lower end surface of the sealing cylinder 19, and the telescopic sleeve 20 can be movably telescopic. A sealing ring 21 is fixedly connected to one end surface of the sealing cylinder 19 of the telescopic sleeve 20. The sealing ring 21 is made of silicone rubber and has good high temperature resistance. At the same time, an inner cylinder 22 which is connected to the nozzle end of the universal bamboo joint tube 59 is arranged inside the sealing cylinder 19, and a plurality of guide surfaces 23 are arranged around the inner wall of the inner cylinder 22. The guide surfaces 23 are inclined from bottom to top, and the inclination angle is 60°. A circulation cavity 24 for gas circulation is reserved between the outer surface of the inner cylinder 22 and the inside of the sealing cylinder 19. An air outlet pipe 25 is sealantly connected to one end of the outer surface of the sealing cylinder 19. The air outlet pipe 25 passes through the sealing cylinder 19 and is connected to the circulation cavity 24, and the end of the air outlet pipe 25 away from the sealing cylinder 19 is connected to an air flow generating device.

[0047] It should be noted that the inner circle width of the guide surface 23 is greater than the outer surface width of the bottle body mold 10 , and the distance between the sealing ring 21 and the tray 9 is consistent with the distance between the pinch clamp 57 and the preset fracture of the bottle body mold 10 .

[0048] The implementation principle of Example 3 is as follows: when the pinch-off pliers 57 pinch off the second group of bottle body molds 10, the disassembly plate 53 is lowered as a whole, thereby driving the gas delivery seat 58 to press down the nozzle of the universal bamboo tube 59, and as the nozzle is pressed down, the sealing cylinder 19 is pressed down synchronously. When the pinch-off pliers 57 are lowered to the fracture of the bottle body mold 10, the sealing cylinder 19 is pressed down to drive the sealing ring 21 to abut against the surface of the tray 9 to form a seal, and the telescopic sleeve 20 has a certain elasticity to prevent the sealing cylinder 19 from being excessively pressed down to cause the sealing ring 21 to be squeezed and deformed to cause air leakage; At this time, the inner wall of the inner cylinder 22 and the surface of the bottle mold 10 are in an inserted state, and the guide surface 23 is arranged around the outer surface of the bottle mold 10. When the universal bamboo tube 59 sprays the high-temperature airflow downward, the airflow first contacts the circular surface at the top of the bottle mold 10 and then diffuses obliquely around, so that part of the high-temperature gas flows downward into the side surface of the bottle mold 10, and the remaining high-temperature gas contacts the guide surface 23 and flows upward along the inner cylinder 22 under the oblique guidance, thereby forming a reflux, and then blown downward from the top of the bottle mold 10 again. The multiple guide surfaces 23 allow the high-temperature gas to form a second or even multiple circulation, thereby improving the smooth effect of the bottle mold 10. Then, the airflow flowing out from the bottom of the inner tube 22 is blocked by the tray 9, and the universal bamboo tube 59 continuously outputs high-temperature airflow to form thrust, so that the outflowing airflow is blown upward along the flow cavity 24, and then flows back to the airflow generating device through the air outlet pipe 25 for secondary utilization.

For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
