Description

Technical Field

[0001] The invention relates to the technical field of blister machines, in particular to a HDPE blister tray forming device for packaging in an automobile production line. Background Art

[0002] HDPE (High Density Polyethylene) is a commonly used plastic material with good durability and strength, suitable for making various packaging trays and trays. In the automotive production line, this blister tray is often used to transport and store parts or components to protect them from damage or contamination. HDPE blister trays need to be blister-formed during the production process. The thermoplastic plastic sheet is heated to the softening point, and then the softened plastic sheet is pressed against the mold surface by vacuum adsorption or compressed air. After cooling, the product is formed into the desired shape.

[0003] In the process of blister forming, a blister machine is needed for blister forming. A general blister machine includes a workbench, a blister slot, a mold, a heating device, a fixing device, an air suction device and an air blowing device. When blister forming, the staff first places the HDPE sheet on the workbench, aligns it with the blister slot, and then uses a fixing device to fix the HDPE sheet. Then the heating device is moved to the top of the HDPE sheet to heat the HDPE sheet to soften the HDPE sheet. Then the heating device is removed, and the air blowing device blows air under the HDPE sheet to make the middle part of the HDPE sheet bulge. At this time, the mold rises, and then the air suction device sucks away the air between the HDPE sheet and the mold, so that the softened HDPE sheet is tightly attached to the mold. After the HDPE sheet is cooled and hardened, the formed HDPE sheet is cut to complete the forming process of the HDPE blister tray.

[0004] As in the prior art, the patent with patent authorization announcement number CN114407343B discloses a blister machine for door panel processing, including a film roll, a blister assembly, a mounting platform, a compaction and heating device, a film processing device and a cutting device. The film roll, the blister assembly and the compaction and heating device are all fixedly arranged on the ground, the mounting platform is fixedly arranged on the blister assembly, the compaction and heating device is located on the upper side of the mounting platform, the film processing device and the cutting device are fixedly arranged on the mounting platform, the blister assembly includes a suction device and a ventilation box fixedly arranged on the ground, a bearing platform is fixedly arranged on the upper surface of the ventilation box, the mounting platform is fixedly arranged on the outside of the ventilation box as a bearing platform for each component, the compaction and heating device includes a compaction power cylinder fixedly arranged on the ground, the piston rod of the compaction power cylinder is fixedly connected to the fixed plate, a compaction and heating hood is fixedly arranged on the fixed plate, the compaction and heating hood is a hood with an opening facing downward, and a heating device for heating is arranged inside the compaction and heating hood.

[0005] The existing blister machines have certain defects when in use; some processing aids, such as heat stabilizers, antioxidants, etc., are added to the HDPE sheets during the production process. The decomposition temperature of these substances is lower than that of the HDPE material. Therefore, during the heating and softening process of the HDPE sheets, these processing aids may decompose before the HDPE material and release harmful gases. The existing blister machines cannot remove these harmful gases. The released harmful gases will accumulate in the working environment, causing the air quality to deteriorate. Long-term exposure to such an environment may irritate the respiratory system, skin and eyes of factory employees, causing more serious health problems. At the same time, these harmful gases may also be corrosive, causing corrosion to the metal parts inside the blister machine, shortening the life of the equipment and increasing the cost of maintenance and replacement of parts.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] See also Figure 1-Figure 14 A HDPE blister tray forming device for packaging of an automobile production line comprises a workbench 1 and a blister groove 2 arranged on the workbench 1, a connecting ring 3 is connected to the surface of the workbench 1, the blister groove 2 is located at the center of the connecting ring 3, a plurality of air suction ports 4 are equidistantly provided on the inner side of the connecting ring 3, a plurality of air guide grooves 5 connected to the air suction ports 4 are provided in the connecting ring 3, a plurality of exhaust pipes 6 are fixedly connected to the outer side of the connecting ring 3, the exhaust pipes 6 are connected to the air guide grooves 5 in a one-to-one correspondence, an air guide pipe 7 is connected to the surface of the workbench 1, the air guide pipe 7 comprises an annular pipe 71 and a connecting pipe 72, the exhaust pipes 6 are all connected to the annular pipe 71, an adsorption component 8 is fixedly connected to one end of the connecting pipe 72, a guide sleeve 9 is connected to the bottom of the adsorption component 8, an exhaust fan 10 is fixedly connected to the lower end of the guide sleeve 9, and the exhaust fan 10 and the adsorption component 8 are both fixedly connected to the side wall of the workbench 1.

[0038] The HDPE blister tray forming device for automobile production line packaging in the present invention, when blister forming the HDPE sheet, first put the HDPE sheet in the middle of the connecting ring 3, align it with the blister groove 2, and then fix the HDPE sheet. Then the heating device moves to the HDPE sheet to heat and soften the HDPE sheet. At this time, the exhaust fan 10 is started. With the operation of the exhaust fan 10, the volatile organic compounds and other harmful gases generated in the heating process are quickly and effectively sucked in through the air intake port 4, and then transmitted to the exhaust pipe 6 along the air guide groove 5, and then enter the adsorption component 8 through the annular pipe 71 and the connecting pipe 72. The volatile organic compounds and other harmful gases in the gas are adsorbed by the adsorption component 8, leaving only relatively clean gas, which is then discharged to the outside of the workshop by the exhaust fan 10. Through the mutual cooperation of the exhaust fan 10 and the connecting ring 3, the harmful gases generated in the heating and softening process of the HDPE sheet are treated, and the pollution of the workshop environment by harmful substances and the potential threat to the health of employees are avoided. , achieving effective protection of the working environment and efficient purification of the gas, while reducing corrosion to the metal parts inside the equipment, extending the service life of the equipment, and reducing the frequency and cost of replacing parts; on the other hand, the heating device often emits strong light and heat. Long-term direct exposure will not only cause eye fatigue to the staff, but may also cause problems such as blurred vision and dry eyes, affecting work efficiency and employee health. The connecting ring 3 can block the heating device, and reduce the intensity of light directly irradiating the working area by physical blocking, creating a more comfortable visual environment for the staff, helping to maintain good visual health and improve work durability, while also reducing operational errors caused by visual fatigue and improving production safety; the suction generated by the exhaust fan 10 can also take away dust above the HDPE sheet, avoiding dust from adhering to the heated and softened HDPE sheet, which may cause defects on the surface of the finished product, helping to ensure a smooth and clean surface of the blister tray and improve the overall quality of the product.

[0039] As a preferred technical solution of the present invention, the adsorption assembly 8 includes a fixed cover 81, a connecting tube 82, a sieve plate 83 and activated carbon 84. The top of the fixed cover 81 is connected to the connecting pipe 72, the top of the connecting tube 82 is detachably connected to the lower part of the fixed cover 81, the lower end of the connecting tube 82 is fixedly connected to the upper end of the guide sleeve 9, the inner wall of the connecting tube 82 is fixedly connected with the sieve plate 83, and the activated carbon 84 is placed on the surface of the sieve plate 83.

[0040] Specifically, as a highly efficient adsorption material, activated carbon 84 has a large number of microporous structures inside that can effectively adsorb and lock volatile organic compounds and other harmful gas molecules, and separate harmful substances from the gas through the dual effects of physical adsorption and chemical adsorption. Compared with other adsorption materials, after being saturated with adsorption, activated carbon 84 can be regenerated by heating or treating with chemical reagents under specific conditions to restore its adsorption capacity, which has a longer service life and can reduce long-term treatment costs, in line with the principle of sustainable development.

[0041] As a preferred technical solution of the present invention, the connecting ring 3 includes a front plate 31, two side plates 32 and a back plate 33. Three rotating components are connected to the surface of the workbench 1. The rotating components correspond to the positions of the front plate 31 and the two side plates 32 respectively. The rotating components include a fixed block 11 and a rotating shaft 13. The outer sides of the bottoms of the front plate 31 and the two side plates 32 are provided with fixed grooves 12 corresponding to the positions of the fixed blocks 11. The rotating shaft 13 is fixedly connected to the fixed block 11. The inner wall of the fixed groove 12 is provided with a rotating groove 14 corresponding to the position of the rotating shaft 13. Limiting components are connected to both ends of the surface of the front plate 31.

[0042] Specifically, when the staff is placing and taking the HDPE sheet, the connecting ring 3 will cause certain obstacles to the staff. At this time, the staff opens the limit assembly and then rotates the front plate 31 and the side plate 32 along the rotating shaft 13, which can significantly enhance the accessibility of the working area and provide the staff with a more spacious and barrier-free operating space, so that they can more conveniently place and adjust the position of the HDPE sheet and reduce the risk of misoperation.

[0043] As a preferred technical solution of the present invention, the limiting assembly includes a limiting member 18, which is a U-shaped rod. The surfaces of the front plate 31 and the side plate 32 are respectively provided with limiting holes 17 corresponding to the positions of the two ends of the limiting member 18.

[0044] Specifically, when it is necessary to open the connecting ring 3, the staff can pull out the limit piece 18 upwards to separate the limit piece 18 from the limit hole 17, and then rotate the front plate 31 and the side plate 32 to put in or take out the HDPE sheet; when it is necessary to fix the front plate 31 and the side plate 32, the two ends of the limit piece 18 are inserted into the preset limit holes 17 on the surface of the front plate 31 and the side plate 32. The design of the U-shaped rod can tightly clamp the limit hole 17 to ensure that during the vacuum forming process, the connecting ring 3 remains fixed and will not move accidentally due to machine vibration or external force, thereby ensuring the processing accuracy and safety.

[0045] As a preferred technical solution of the present invention, rotating rods 15 are fixedly connected on both sides of the front plate 31, and the two side plates 32 are fixedly connected on one side close to the front plate 31. The outer wall of each rotating rod 15 is fixedly connected to a bevel gear 16, and the bevel gear 16 located on the front plate 31 is meshed with the bevel gear 16 located on the side plate 32.

[0046] Specifically, when the staff rotates the front plate 31, the rotating rods 15 installed on both sides of the front plate 31 rotate accordingly, and then the bevel gears 16 fixed on the outer wall of the rotating rods 15 also start to rotate. Since these bevel gears 16 are meshed with the bevel gears 16 installed on the two side plates 32, the rotational motion is transmitted to the bevel gears 16 on the side plates 32 through the gear transmission mechanism, thereby driving the two side plates 32 to rotate synchronously; through this arrangement, the staff only needs to rotate the front plate 31 to open and close the front plate 31 and the side plates 32, which simplifies the operation process, makes the whole process smoother and faster, and improves the operation convenience and safety of the entire blister molding device.

[0047] As a preferred technical solution of the present invention, a handle 26 is fixedly connected to the middle of the surface of the front plate 31 , and an insulating sleeve 27 is provided on the outer wall of the handle 26 .

[0048] Specifically, the handle 26 can bring convenience to the staff to rotate the front plate 31, so that the staff has a clear and comfortable fulcrum when rotating the front plate 31, which improves the convenience and comfort of operation and significantly reduces the difficulty of operation; the insulation sleeve 27 is arranged on the outer wall of the handle 26, and its main function is to isolate heat. During the heating and blister forming process, some parts of the equipment may become quite hot. The insulation sleeve 27 can effectively prevent heat from being transferred to the surface of the handle 26, thereby protecting the staff from burns, ensuring safe operation, and preventing the staff from slipping.

[0049] As a preferred technical solution of the present invention, the inner bottom of the front panel 31, the side panel 32 and the back panel 33 are all fixedly connected to the limiting plate 19, the bottom surface of each limiting plate 19 close to the blister groove 2 is fixedly connected to the positioning rod 20, and the bottom surface of the back panel 33 is connected to the lifting assembly.

[0050] Specifically, before placing the HDPE sheet, the front plate 31 and the side plate 32 will be opened, and the back plate 33 will rise under the action of the lifting component. At this time, the staff will place one side of the HDPE sheet under the limit plate 19 connected to the back plate 33, align the HDPE sheet with the blister groove 2, and then the lifting component will drive the back plate 33 to descend, so that the limit plate 19 on the back plate 33 is close to the HDPE sheet until the positioning rod 20 contacts the HDPE sheet to fix one side of the HDPE sheet. Then the staff will rotate the front plate 31 through the handle 26. At this time, the limit plate 19 connected to the front plate 31 and the side plate 32 will rotate accordingly, so that the four positioning rods 20 will contact the four sides of the HDPE sheet respectively, and fix the four sides of the HDPE sheet, thereby ensuring the stability of the position of the HDPE sheet during the entire heating and molding process, avoiding movement or offset, and improving the molding accuracy and quality of the finished product.

[0051] As a preferred technical solution of the present invention, the lifting assembly includes a movable plate 24, a spring 22 and a positioning column 23. The limit plates 19 located on the two side plates 32 are fixedly connected to the movable plate 24 at one end close to the back plate 33. The bottom surface of the movable plate 24 is in contact with the surface of the limit plate 19 connected to the back plate 33. Two symmetrically arranged connecting grooves 21 are provided on the bottom surface of the back plate 33. A spring 22 is fixedly connected in each connecting groove 21. The other end of the spring 22 is fixedly connected to the surface of the workbench 1. Two positioning columns 23 corresponding to the positions of the connecting grooves 21 are fixedly connected to the surface of the workbench 1.

[0052] Specifically, when the staff needs to lower the back plate 33, the front plate 31 rotates, and the front plate 31 drives the side plate 32 to rotate, and the connected movable plate 24 on the side plate 32 rotates accordingly. During the rotation, the movable plate 24 will contact the limit plate 19 on the back plate 33, press the limit plate 19 downward, and then drive the back plate 33 to descend, thereby fixing the HDPE sheet; when the back plate 33 needs to be lifted, the front plate 31 is opened, and the limit plate 19 is separated from the movable plate 24. At this time, under the pressure of the spring 22, the back plate 33 will move along the positioning column 23, thereby realizing the rising of the back plate 33; through this setting, through clever mechanical linkage, the staff only needs to control the rotation of the front plate 31 to control the lifting and lowering of the back plate 33, which simplifies the operation process, improves work efficiency, reduces the complexity and time of manual intervention, and reduces the possibility of operation errors, ensuring the stability and consistency of each operation.

[0053] As a preferred technical solution of the present invention, a threaded tube 25 is fixedly connected to the top of the connecting tube 82 , and the bottom inner wall of the fixed cover 81 is threadedly connected to the outer wall of the threaded tube 25 .

[0054] Specifically, by using the threaded tube 25, the staff can easily separate the connecting tube 82 from the fixed cover 81, so as to replace and regenerate the activated carbon 84 in the connecting tube 82 and clean the connecting tube 82, thereby improving the convenience of maintenance and the continuous operation capability of the system.

[0055] As a preferred technical solution of the present invention, magnetic plates 28 are fixedly connected on both sides of the front panel 31, and magnetic plates 28 are fixedly connected on one side of the two side panels 32 close to the front panel 31. The magnetic plates 28 connected to the front panel 31 are adsorbed one by one with the magnetic plates 28 connected to the side panels 32.

[0056] Specifically, the magnetic plate 28 is made of high-temperature resistant magnetic materials, such as neodymium iron boron alloy; after the limit member 18 has been used for a long time, the limit member 18 and the limit hole 17 will be worn, resulting in a gap at the connection between the front plate 31 and the side plate 32. During the overall operation of the device, the front plate 31 and the side plate 32 will continue to shake and collide, generating noise. At this time, the magnetic force of the magnetic plate 28 can effectively shorten and maintain the distance between the front plate 31 and the side plate 32, make up for the gap caused by wear, ensure the firmness of the connection, and avoid shaking and unnecessary collisions caused by loose connections, thereby significantly reducing the mechanical vibration and noise during equipment operation, creating a quieter working environment for operators, and helping to improve the comfort of the workplace.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
