Description
Technical Field
[0001] This utility model relates to the technical field of inflatable cushioning and vibration damping pad production equipment, specifically to an inflatable cushioning and vibration damping pad hot pressing line generation device. Background Technology
[0002] The hot-pressing line generating device for inflatable cushioning and vibration damping pads is the production equipment for inflatable cushioning and vibration damping pads. The inflatable cushioning and vibration damping pads not only include the cushioning and vibration damping pad body composed of two layers of thick plastic film, but also include an air valve composed of two layers of plastic film. During production, the above-mentioned film layers are stacked together, and then the hot-pressing line generating device for inflatable cushioning and vibration damping pads is used to hot-press the film layers together. During hot pressing, there are not only continuous hot-pressing lines, but also non-connected hot-pressing lines. For continuous hot-pressing lines, a closed connection is formed between the layers, while for non-connected hot-pressing lines, a non-closed connection is used between the layers. The gap between the hot-pressing points is an airflow port.
[0003] In the existing hot-pressing line production device for inflatable cushioning and vibration damping pads, after the upper and lower hot-pressing molds have finished hot-pressing the film, the film cannot be removed from the lower hot-pressing mold in time. The high-temperature lower hot-pressing mold continues to heat the film, and the overheated film will be damaged, resulting in a low yield of the produced inflatable cushioning and vibration damping pads. Utility Model Content
[0004] The purpose of this invention is to provide an inflatable cushioning and vibration damping pad hot pressing line generation device that can improve the hot pressing effect and product yield.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A device for generating hot-pressed lines on an inflatable cushioning and vibration damping pad includes a base, a hot-pressing support body, an upper hot-pressing die, a lower hot-pressing die, a drive mechanism, a transmission pressing component, and a spring-loaded separation platform. The upper hot-pressing die and the transmission pressing component are located on the lower surface of the hot-pressing support body, and the lower hot-pressing die is located on the upper surface of the base and below the upper hot-pressing die. The spring-loaded separation platform is located on the base, and the hot-pressed film is located on the surface of the spring-loaded separation platform. The drive mechanism is used to drive the upper hot-pressing die and the transmission pressing component to move up and down through the hot-pressing support body. The transmission pressing component is used to press the spring-loaded separation platform downward, so that the spring-loaded separation platform is compressed downward until the hot-pressed film contacts the lower hot-pressing die. The upper hot-pressing die and the lower hot-pressing die are used to heat-press the hot-pressed film from the top and bottom respectively, so as to form hot-pressed lines on the surface of the hot-pressed film. The spring-loaded separation platform is used to separate the hot-pressed film and the lower hot-pressing die after the hot-pressed lines are generated.
[0006] Furthermore, the rebound separation platform includes a guide column, a separation plate, and a spring. The guide column is mounted on the machine base. The separation plate has a guide hole and a through hole on its surface. A guide sleeve is installed in the guide hole. The separation plate passes through the guide sleeve onto the guide column. The spring is mounted on the guide column and is located between the separation plate and the machine base. The through hole is located above the lower die of the hot press. The transmission pressing component presses the separation plate downward, and the lower die of the hot press passes upward through the through hole.
[0007] Furthermore, the spring-loaded separation platform also includes a left spring-loaded limiting plate, a left spring-loaded limiting post, a left locking screw, a right spring-loaded limiting plate, a right spring-loaded limiting post, and a right locking screw. Both the left and right spring-loaded limiting plates have vertical elongated holes on their surfaces. The left and right locking screws pass through these elongated holes to fix the left and right spring-loaded limiting plates to the left and right side walls of the machine base, respectively. The left and right locking screws are used to adjust the distance between the separation plate and the machine base to adjust the spring force. The left and right spring-loaded limiting posts are fixed to the left and right sides of the separation plate and are respectively inserted into the elongated holes of the left and right spring-loaded limiting plates. When the separation plate moves up and down, the left and right spring-loaded limiting posts slide along the elongated holes.
[0008] Furthermore, there are two guide columns, which are located on both sides of the hot press lower mold.
[0009] Furthermore, the upper end of the guide column is provided with a fixed connecting plate, and the two ends of the fixed connecting plate are respectively fixedly connected to the upper ends of the two guide columns, and the driving mechanism is installed on the fixed connecting plate.
[0010] Furthermore, the driving mechanism is a cylinder or an electric push rod.
[0011] Furthermore, the transmission pressing component includes a screw and a locking nut. The locking nut fixes the screw to the hot-pressing support and can adjust the height of the screw.
[0012] Furthermore, the hot-pressing line has mounting holes on the die, through which an electric heating rod is inserted. This mounting structure greatly facilitates the subsequent maintenance of the electric heating rod.
[0013] Furthermore, the hot-pressed support body is a buffered elastic support body.
[0014] Furthermore, the buffer elastic support body includes an upper support plate, a lower support plate, a left connecting plate, a left connecting screw, a left sliding column, a right connecting plate, a right connecting screw, a right sliding column, and a buffer spring. The upper and lower support plates are inserted into the guide column, and the buffer spring is fitted onto the guide column and located between the upper and lower support plates. The left and right connecting plates are fixed to the left and right ends of the lower support plate by the left and right connecting screws, respectively. The left and right sliding columns are fixed to the left and right ends of the upper support plate and are inserted into the elongated sliding holes on the surface of the left and right connecting plates, respectively. When the buffer spring extends or retracts, the left and right sliding columns slide along the elongated sliding holes. The upper support plate is installed at the lower end of the power output rod of the drive mechanism, and the hot-pressing line mold is installed on the lower support plate of the buffer elastic support body.
[0015] The beneficial effects of this utility model are as follows: This application adds a spring-loaded separation platform to the machine base. The transmission top pressing component and the spring-loaded separation platform cooperate to make the hot-pressed film and the lower die of the hot pressing machine come into contact. After the hot pressing is completed, the transmission top pressing component moves up and resets quickly. The spring-loaded separation platform can quickly separate the hot-pressed film and the lower die of the hot pressing machine under its own elasticity. This solves the problem of damage to the hot-pressed film caused by excessive heating of the lower die of the hot pressing machine due to the hot-pressed film remaining on it, and improves the hot pressing effect and the yield of the product.

During hot pressing, the drive mechanism 5 drives the hot pressing upper die 3 and the transmission top pressing component 6 to move downward. The transmission top pressing component applies pressure to the spring-loaded separation platform, causing the spring-loaded separation platform to move downward and the hot pressing lower die 4 to pass upward through the through hole 12, so as to achieve the purpose of contact between the hot-pressed film and the hot-pressed lower die. After hot pressing is completed, the spring-loaded separation platform can quickly separate the hot-pressed film and the hot-pressed lower die, so as to solve the problem of damage to the hot-pressed film due to excessive heating caused by the hot-pressed film remaining on the hot-pressed lower die, thereby improving the hot pressing effect and the product yield.
