Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat sealing machine technology, and in particular to a heat pressing and edge cutting integrated machine. Background Technology
[0002] A heat sealing machine is a device used to heat seal plastic films or packaging materials. It uses high-temperature heating elements to heat the plastic film to its melting point and applies external force to make it come into contact with other surfaces and cool it, thereby achieving the purpose of sealing.
[0003] Currently available heat sealing machines generally include a base, on which a base plate and a heat sealing mold are mounted. The heat sealing mold slides vertically on the base. A cylinder on the base drives the heat sealing mold to move up and down. A push plate is also mounted at the output end of the cylinder, and a spring is installed between the push plate and the heat sealing mold. During operation, the product is placed on the base plate, then the cylinder is activated, driving the push plate and heat sealing mold to move downwards together. When the heat sealing mold presses against the product, the spring is compressed, thus heat sealing the product.
[0004] However, the aforementioned heat sealing machine has a drawback: a spring is installed between the push plate and the hot pressing mold. The product is hot-pressed by the spring force in conjunction with the hot pressing mold. However, due to different degrees of spring deformation, the resulting elastic force is also different. The pressure exerted on the product by the spring gradually increases during the deformation process. Therefore, it is difficult to control and adjust the final pressure on the product during the hot pressing process. If the final pressure is too low, the two heat-sealed films are easy to separate. If the pressure is too high, the film is easy to be burned. Moreover, different film thicknesses require different pressure levels. If a different type of film product is used, different springs and other parts need to be replaced and adjusted again, which is quite troublesome to operate. Utility Model Content

The first cylinder is provided with a conduit connected to an air pump and, after being inflated, causes the piston rod of the first cylinder to be in an extended state. A pressure relief valve is connected to the conduit.
[0008] Optionally, the hot die head is connected to the piston rod end of the first cylinder by bolts. The hot die head is provided with a through groove for the threaded section of the bolt to pass through. The piston rod end of the first cylinder is provided with a threaded hole that matches the bolt. The hot die head is provided with a stepped groove for the nut end of the bolt to be hidden.

[0013] In summary, this application includes at least one of the following beneficial technical effects:
[0014] This application discloses a hot pressing and trimming integrated machine. During operation, an air pump continuously inflates the first cylinder, keeping the piston rod of the first cylinder in an extended state. The air pressure inside the first cylinder is controlled by a pressure relief valve. When the hot pressing mold reaches the set value, the drive device continues to push the push plate downwards, causing the piston rod of the first cylinder to retract inwards, increasing the air pressure inside the first cylinder. When the air pressure inside the first cylinder exceeds the value set by the pressure relief valve, the pressure relief valve releases pressure, ensuring that the air pressure inside the first cylinder does not exceed the set standard. Therefore, during the hot pressing process, the pressure exerted on the product is kept as balanced as possible, and the pressure can be adjusted simply by adjusting the pressure relief valve, making adjustment more convenient and quick.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0021] This application discloses a hot pressing and edge-cutting integrated machine. (Refer to...) Figure 1 and Figure 2The system includes a base 2, on which a base 3 and a hot press mold 4 are mounted. The base 3 and the hot press mold 4 are arranged vertically and vertically respectively. The hot press mold 4 is slidably connected to the base 2. The base 2 is equipped with a drive device 5 for driving the hot press mold 4 to move up and down. The hot press mold 4 includes a mold base 41 and a hot mold head 42. The mold base 41 is connected to the output end of the drive device 5. The mold base 41 is equipped with a slide groove 6 for the hot mold head 42 to slide up and down. The hot mold head 42 is slidably mounted in the slide groove 6. The mold base 41 is equipped with a first cylinder 7, a second cylinder 8, and a third cylinder 9. The piston rod 10 of the first cylinder 7 passes through the mold base 41 and is connected to the hot mold head 42. The mold base 41 is provided with a through hole 8 for the piston rod 10 of the first cylinder 7 to slide up and down. The sliding direction of the piston rod 10 of the first cylinder 7 is the same as the sliding direction of the hot mold head 42. The end of the hot mold head 42 relative to the base 3 extends to the outside of the slide groove 6. The first cylinder 7 is provided with a conduit 9 connected to an air pump. The air pump continuously fills the first cylinder 7 with air, so that the piston rod 10 of the cylinder is always in an extended state. A pressure relief valve 1 is connected to the conduit 9. During the hot pressing process, the pressure of the pressure relief valve 1 is pre-adjusted. Then, the product to be hot pressed is placed on the base 3, and the hot pressing mold 4 is pushed down by the drive device 5 so that the hot mold head 42 presses onto the product. The drive device 5 continues to push the mold base 41 down. During this process, the hot mold head 42 and the mold base 41 will move relative to each other. The hot mold head 42 will move into the slide groove 6. At the same time, the piston rod 10 of the first cylinder 7 will also move up with the hot mold head 42. The air pressure inside the first cylinder 7 will increase. When the air pressure inside the first cylinder 7 is greater than the value set by the pressure relief valve 1, the pressure relief valve 1 will release the internal pressure so that the air pressure inside the first cylinder 7 will not exceed the set standard. This allows the pressure of the hot pressing on the product to be kept as balanced as possible. Moreover, the pressure of the hot pressing can be adjusted by simply adjusting the pressure relief valve 1, making the adjustment more convenient and quick.
[0022] The hot die head 42 is connected to the end of the piston rod 10 of the first cylinder 7 by bolts 12. The hot die head 42 has a through groove 11 for the threaded section of the bolt 12 to pass through, and the end of the piston rod 10 of the first cylinder 7 has a threaded hole 13 that matches the bolt 12. The hot die head 42 also has a stepped groove 14 for concealing the nut end of the bolt 12. The connection between the hot die head 42 and the end of the piston rod 10 of the first cylinder 7 by bolts 12 allows for easy replacement of different hot die heads 42 to accommodate more hot pressing requirements.
[0023] The mold base 41 includes a base body 411 and an annular cutter 412. A mounting groove 413 is provided on the base body 411, and the annular cutter 412 is fixedly installed within the mounting groove 413, with its cutting edge protruding outside the groove 413. A hot mold head 42 is slidably mounted within the annular cutter 412, with its end protruding outside the cutter. When the hot mold head 42 is hot-pressed onto the product, the base body 411 and the annular cutter 412 move downwards together under the action of the drive device 5. The hot mold head 42 slides into the base body 411. When the annular cutter 412 contacts the product, it can perform annular cutting. Thus, the product can be annularly cut immediately after hot pressing, allowing both processes to be completed on one machine, improving processing efficiency.
[0024] Reference Figure 1 , Figure 2 and Figure 3 The base 2 includes an upper plate 21 and a lower plate 22. Four guide posts 23 are provided between the upper plate 21 and the lower plate 22. The guide posts 23 are fixed to the upper plate 21 and the lower plate 22 by screws. The drive device 5 includes a second cylinder 51, a push plate 52, a sliding sleeve 53 and four connecting posts 54. The push plate 52 is provided with a mounting hole 55 for mounting the sliding sleeve 53. The sliding sleeve 53 includes a sleeve body 531 and a flange 532. The sleeve body 531 and the flange 532 are integrally set. The sleeve body 531 passes through the mounting hole 55 and the flange 532 is fixed to the push plate 52 by screws. The sliding sleeve 53 is slidably sleeved on the guide posts 23. The connecting posts 54 are connected between the push plate 52 and the base 411.
[0025] Reference Figure 4 The base 3 is provided with an elastic clip 15 for fixing the product. One end of the elastic clip 15 is fixed to the base 3 by screws. The base 3 is provided with a limiting strip 16, and the limiting strip 16 is provided with a waist-shaped hole 17. The limiting strip 16 is fixed to the base 3 by screws.
[0026] The pressure relief valve 1 is fixedly installed on the upper plate 21 by screws. The conduit 9 includes a first tube 91 and a second tube 92. The first tube 91 is connected to the pressure relief valve 1 and the first cylinder 7 respectively, and the second tube 92 is connected to the pressure relief valve 1 and the air pump respectively.
[0027] The implementation principle of the hot pressing and trimming integrated machine in this application embodiment is as follows: Before hot pressing, first confirm the set value of the pressure relief valve 1, and adjust it to the corresponding value if necessary. Then, start the air pump to inflate the first cylinder 7 so that the piston rod 10 of the first cylinder 7 is in the extended state. Then, start the drive device 5, which pushes the hot pressing mold 4 downward. When the hot mold head 42 presses against the product, the hot mold head 42 will stop moving, and the mold base 41 will continue to move downward for a certain distance before stopping. During this process, the hot mold head 42 and the mold base 41 will generate relative... As the hot mold head 42 moves into the slide groove 6, the piston rod 10 of the first cylinder 7 also moves upward along with the hot mold head 42, increasing the air pressure inside the first cylinder 7. When the air pressure inside the first cylinder 7 exceeds the value set by the pressure relief valve 1, the pressure relief valve 1 will release the internal pressure to ensure that the air pressure inside the first cylinder 7 does not exceed the set standard. The product is hot-pressed by the pressure of the hot mold head 42 and the air pressure inside the first cylinder 7. After the hot pressing is completed, the drive device 5 drives the mold base 41 to move downward, and the product is then circumferentially cut by the annular cutter 412.
[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
