Description

[0002] Thermal insulation sheet is a material used to block heat transfer and is widely used in construction, electronics, automobiles, aviation and other fields; especially with the vigorous development of the new energy vehicle industry, thermal insulation sheet is widely used in new energy vehicles.

[0003] Thermal insulation sheets typically consist of an insulation layer and a sealing film. The insulation layer can be made of materials such as aerogel, ceramic fiber, and asbestos, while the sealing film can be made of polymer materials such as PET, PI, and PVC. The performance of the insulation sheet is primarily determined by the thermal conductivity of the insulation layer and the sealing properties of the sealing film.

[0004] The production process of thermal insulation sheet generally includes the following steps: first, the insulation layer and sealing film are cut and spliced ​​to form the product to be packaged; then, the product to be packaged is placed in the packaging machine, and operations such as vacuuming, heating, and pressing are performed to ensure that the sealing film and the insulation layer are tightly attached, and bubbles and wrinkles are eliminated to form a complete thermal insulation sheet; finally, the packaged thermal insulation sheet is removed for subsequent processing such as inspection and packaging;

[0005] However, the traditional packaging process requires placing the product in a frame and then placing it in a packaging machine. This is time-consuming and labor-intensive, and requires strict control of the size of the product and the frame. In addition, traditional packaging machines have difficulty fully eliminating bubbles between the sealing film and the insulation sheet in the product, and a small amount of air still remains in the final product, resulting in room for improvement in product quality.

[0036] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] Example 1: The present invention provides a technical solution: a fully automatic hot-pressing packaging production process for thermal insulation sheets, the process comprising the following steps:

[0038] S1. Place the product to be packaged: manually open the cabinet door 3, then place the product to be packaged on the bottom carrier 101, and then close the cabinet door 3;

[0039] S2. Pre-evacuation: The air in the package housing 1 is evacuated to a vacuum state through the cooperation of the driven guide rod 20, the piston cylinder 21, the piston plate 22, the one-way air inlet valve 23 and the one-way air outlet valve 24;

[0040] S3, sliding extrusion: The electrically heated scraper 5 slides on the product to be packaged to squeeze the air between the sealing film and the heat insulation sheet on the product to be packaged, making the sealing film and the heat insulation sheet fit more tightly and removing wrinkles at the same time;

[0041] S4, heating treatment: After the electric heating scraper 5 is connected to the power supply, the electrical energy is converted into heat energy to accelerate the packaging efficiency and quality;

[0042] S5, material taking operation: The four electrically heated scrapers 5 and the contraction scraping strips 9 thereon move centripetally to scoop up the packaged products, and then the cabinet door 3 is manually opened to manually take out the scooped products. Example 2:

[0043] On the basis of Example 1, further: it includes a packaging shell 1, the surface of the packaging shell 1 is provided with a display screen 2 for displaying production data and a cabinet door 3 for placing and taking materials, the packaging shell 1 is provided with a C-shaped arm 4 driven to move horizontally back and forth, the bottom of the C-shaped arm 4 is slidingly connected to an electric heating scraper 5, the surface of the electric heating scraper 5 is fixedly connected to a connecting plate 6 arranged parallel to the C-shaped arm 4, the connecting plate 6 and the opposite surface of the C-shaped arm 4 parallel thereto are fixedly connected with a telescopic spring 7, the lower surface of the packaging shell 1 is penetrated and detachably installed with a bottom carrier plate 101 for supporting the product to be packaged.

[0044] Refer to Figures 1 and 2;

[0045] The entire device is sealed and supported by the packaging shell 1, and the air pressure, temperature and other data information inside the packaging shell 1 are displayed on the display screen 2; the cabinet door 3 facilitates the product to be taken out and put in;

[0046] The C-shaped arm 4 drives the electric heating scraper 5 to move synchronously. The lower surface of the electric heating scraper 5 contacts and squeezes the upper surface of the product. When the four electric heating scrapers 5 with downward pressure move synchronously on the upper surface of the product, the bubbles between the sealing film and the heat insulation sheet in the product can be squeezed out smoothly, and the potential wrinkles on the sealing film can be smoothed.

[0047] The connection plate 6 and the telescopic spring 7 cooperate to enable the electric heating scraper 5 to perform limited sliding and reset movement on the C-shaped arm 4; this can further increase the centripetal limit position of the four electric heating scrapers 5 and bring the centripetal ends of the four electric heating scrapers 5 closer together, thereby further improving the degree of extrusion and scraping of the product surface.

[0048] By providing the bottom carrier plate 101, when the product is not easy to be placed from the cabinet door 3 to the lower surface of the electric heating scraper 5, the bottom carrier plate 101 can be manually removed, and then the product is placed on the upper surface of the bottom carrier plate 101, and finally the bottom carrier plate 101 is installed on the packaging shell 1, thereby smoothly placing the product on the lower surface of the electric heating scraper 5;

[0049] The direction indicated by arrow A in FIG3 of this solution is the moving direction of the electric heating scraper. Example 3:

[0050] On the basis of Example 2, further:

[0051] The electric heating scraper 5 is provided with a side sealing device for sealing the side of the product. The side sealing device includes a receiving groove 8 opened on the lower surface of the electric heating scraper 5. The inner wall of the receiving groove 8 is connected to the upper and lower limit sliding connection with a retractable scraper strip 9. The top of the retractable scraper strip 9 is fixedly connected to an auxiliary spring 91. The top of the auxiliary spring 91 is fixedly connected to the inner top wall of the receiving groove 8.

[0052] The upper and lower surfaces of the product are squeezed and scraped by the opposing extrusion between the electrically heated scraper 5 and the transmission plate 10. When the electrically heated scraper 5 moves to the edge of the product and is about to leave the upper surface of the product, the bottom of the auxiliary spring 91 will then break away from the upper surface of the product during the movement. Under the elastic force of the auxiliary spring 91, the bottom of the auxiliary spring 91 will be quickly ejected and abut against the upper surface of the bottom carrier plate 101, and then the movement stops. The movement continues for a period of time, and the side of the product is continuously sealed by high temperature.

[0053] Furthermore, there are four electric heating scrapers 5 , which are evenly distributed on the bottom carrier plate 101 .

[0054] The four electrically heated scrapers 5 and their uniform distribution make the surface force of the product more balanced, the movement more stable, and the extrusion and scraping of the product more sufficient. Example 4:

[0055] On the basis of Example 3, further:

[0056] A pressing auxiliary device is provided above the bottom carrier plate 101, and the pressing auxiliary device includes a central pressing plate 11 provided above the bottom carrier plate 101, and a shrinkage column 12 is fixedly connected to the upper surface of the central pressing plate 11. A transmission plate 10 is provided above the central pressing plate 11, and the transmission plate 10 is penetrated and slidably connected by the shrinkage column 12.

[0057] Referring to Figure 3, considering that under extreme circumstances, the centripetal ends of the four electric heating scrapers 5 are still unable to contact and extrude the center of the product, a central pressure plate 11 is provided. As the shrinkage column 12 moves downward, the lower surface of the central pressure plate 11 can contact and extrude the center of the upper surface of the product, and since the shrinkage column 12 can perform a shrinkage operation, the extrusion operation can continue, and after the transmission plate 10 is penetrated by the shrinkage column 12, the movement of the shrinkage column 12 can be limited and supported.

[0058] Furthermore, the shrinkage column 12 includes a shrinkage sleeve 121 and a telescopic push rod 122 that vertically and axially penetrates the shrinkage sleeve 121. The shrinkage sleeve 121 is provided with a compression spring that is vertically placed and abuts against the telescopic push rod 122. The shrinkage sleeve 121 vertically penetrates the transmission plate 10 and is axially slidably connected to the transmission plate 10.

[0059] Refer to Figures 3 and 4.

[0060] In the evacuation to vacuum operation disclosed later, the evacuation operation is carried out continuously. The evacuation operation will continue during the time when the lower surface of the central pressure plate 11 contacts the upper surface of the product and generates extrusion, and the telescopic push rod 122 moves relative to each other in the shrink sleeve 121. This provides time for the evacuation operation and avoids the subsequent electric heating scraper 5 performing heating and scraping operations before vacuum is drawn, causing the residual air to transfer heat and cause waste of heat energy. Under theoretical conditions, the thermal conductivity of the vacuum is zero; therefore, it is necessary to provide the running time of the evacuation operation as much as possible. Secondly, under this operation, a continuous time is also provided for the extrusion exhaust at the center of the product. Example 5:

[0061] On the basis of Example 4, further:

[0062] Four symmetrical and obliquely arranged guide arms 13 are fixedly connected to the upper surface near the edge of the transmission plate 10, and a guide groove 14 is provided on the upper surface near the top of the C-shaped arm 4 to match the inclination angle of the guide arm 13. The surface near the top of the contraction column 12 passes through and is axially limited and slidably connected to a carrier plate 15 supported and fixed by a bracket in the packaging shell 1. The lower surface of the carrier plate 15 is fixedly connected to a limiting arm 16. A section of the limiting arm 16 away from the carrier plate 15 is a horizontal section. The horizontal section on the limiting arm 16 passes through the C-shaped arm 4 and is limited and slidably connected to the C-arm 4.

[0063] Referring to FIG3 , the carrier plate 15 provides support for the equipment running within the packaging housing 1 , and the transmission plate 10 drives the guide arms 13 to rise and fall synchronously. Under the conditions of cooperation with the guide arms 13 on the C-shaped arm 4, the inclined setting of the guide arms 13, and the horizontal section of the limit arm 16 penetrating the C-shaped arm 4 and restricting the movement trajectory of the C-shaped arm 4, when the transmission plate 10 moves downward with the guide arms 13, the four C-shaped arms 4 will synchronously perform horizontal centrifugal motion, and the electrically heated scrapers 5 on the C-arms 4 will also synchronously perform centrifugal motion, thereby achieving a dynamic extrusion operation of the electrically heated scrapers 5 on the product surface;

[0064] Further:

[0065] A synchronous pressure ring 17 penetrates and is fixedly connected to the surface of the shrink sleeve 121 , and the lower surface of the synchronous pressure ring 17 is movably connected to the upper surface of the transmission plate 10 .

[0066] 3 , through the arrangement of the synchronous pressure ring 17 , when the synchronous pressure ring 17 moves downward synchronously with the contraction column 12 , when the lower surface of the synchronous pressure ring 17 contacts and squeezes the upper surface of the transmission plate 10 , the transmission plate 10 will be synchronously moved downward, thereby achieving the related operations caused by the downward movement of the transmission plate 10 described above;

[0067] In actual use, in order to enable the transmission plate 10 to perform the reset operation smoothly, a reset spring for resetting and moving upward can be set on the lower surface of the transmission plate 10. This operation and the reset spring structure are existing technologies well known to those skilled in the art, so they are not shown in the figure. Example 6:

[0068] On the basis of Example 5, further:

[0069] The top of the shrink sleeve 121 is penetrated and threaded with a screw 18, and the top of the screw 18 is coaxially fixedly connected to a cylindrical cam 19. A driven guide rod 20 is slidably connected in the sliding groove on the outer contour of the cylindrical cam 19. The upper surface of the carrier 15 is fixedly connected to the piston cylinder 21. The bottom of the driven guide rod 20 penetrates the upper surface of the piston cylinder 21 and is fixedly connected to a piston plate 22. The surface of the piston plate 22 is slidably connected to the inner wall of the piston cylinder 21. The surface near the bottom of the piston cylinder 21 is penetrated and fixedly connected with a one-way air inlet valve 23 and a one-way air outlet valve 24.

[0070] Refer to Figures 3 and 5;

[0071] Through the screw connection between the screw 18 and the shrinking column 12 and the limited rotation of the shrinking column 12, when the screw 18 rotates, the shrinking column 12 can be raised and lowered accordingly. The specific upward and downward movement is determined by the rotation direction of the screw 18.

[0072] The rotation of the cylindrical cam 19 drives the synchronous rotation of the screw 18. In this solution, the cylindrical cam 19 is driven to rotate by the power mechanism. After the vertical section on the driven guide rod 20 passes through the piston cylinder 21, its motion trajectory is restricted and it cannot rotate. It can only move vertically. As a result, relative motion is generated between the rotating cylindrical cam 19 and the driven guide rod 20. Under the guidance of the outer contour groove on the cylindrical cam 19, the driven guide rod 20 can be raised and lowered. The piston plate 22 on the bottom of the driven guide rod 20 is lifted and lowered accordingly, so that the space at the bottom of the piston cylinder 21 can be increased or decreased, and the air pressure in the space changes accordingly.

[0073] When the volume increases and the air pressure decreases, the air in the packaging shell 1 will enter the bottom space of the piston cylinder 21 through the one-way air inlet valve 23. Conversely, the high-pressure air in the bottom space of the piston cylinder 21 will be transferred outward through the one-way air outlet valve 24. In actual use, an air duct is connected to the exhaust port of the one-way air outlet valve 24 to transfer the air discharged from the one-way air outlet valve 24 to the outside of the packaging shell 1, thereby achieving a vacuum operation of the internal space of the packaging shell 1.

[0074] In this solution, there are four piston cylinders 21, thereby further improving the efficiency of vacuuming;

[0075] The vibration generated by the driven guide rod 20 during the lifting process in the piston cylinder 21 can be transmitted to further improve the efficiency of discharging bubbles in the product;

[0076] Worth mentioning:

[0077] In this solution, the retractable scraper 9 will not be actively received in the receiving groove 8. When the four electrically heated scrapers 5 are moved centripetally by the reverse rotation operation of the cylindrical cam 19, the retractable scraper 9 is in close contact with the edge of the product, and the product can be directly scooped up by the edge of the product, thereby facilitating subsequent manual material collection and improving work efficiency.

[0078] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
