Description

Technical Field

[0001] The utility model relates to the technical field of automatic heat-sealing devices, and more specifically, it relates to an automatic heat-sealing device for hexagonal boron nitride finished products. Background Art

[0003] For example, the existing patent retrieved is: CN219728739U, which discloses an automatic heat-sealing device for hexagonal boron nitride finished products. This existing technology uses this movement law to control the adhesion and separation of the abutment plate and the clamping plate, and at the same time, the heat-sealing film is heat-melted by the heating plate. At the same time, the cutting knife between the two heating plates will cut the sealed heat-sealing film, thereby automatically realizing the sealing and packaging operation of the heat-sealing film, thereby improving the working efficiency of the device.

[0022] See also Figure 1-4 , the utility model provides the following technical solutions:

[0023] Specifically, it refers to an automatic heat-sealing device for hexagonal boron nitride finished products, including an operating table 1, a rear column 2 is fixedly installed on the rear side surface of the operating table 1, a side of the rear column 2 is rotatably connected to a rotating shaft 3, and a mounting shaft 4 is fixedly installed on the other end of the rotating shaft 3. Therefore, when in use, a heat-sealing film roll can be sleeved on the outer surface of the mounting shaft 4, and the mounting shaft 4 is controlled to rotate clockwise, so that the heat-sealing film roll can transport the heat-sealing film.

[0024] A cylinder 5 is fixedly installed on the upper surface of the operating table 1, and a push plate 6 is fixedly installed on one end of the telescopic rod of the cylinder 5. The push plate 6 slides on the operating table 1. Two sliding rods 7 are fixedly installed on the surface of the push plate 6 facing away from the cylinder 5. A support plate 8 is fixedly installed on the operating table 1. The support plate 8 is arranged on the side close to the installation axis 4. The other ends of the two sliding rods 7 slide through the support plate 8. One end of the two sliding rods 7 passing through the support plate 8 is fixedly connected with a clamping plate 9. A heating plate and a cutting knife are arranged on the opposite surfaces of the clamping plate 9 and the support plate 8. The heating plate and the cutting knife are both known technologies in the existing patent: CN219728739U, and no excessive elaboration is made here;

[0025] When in use, the bottom of the heat-sealing film passes through between the clamping plate 9 and the supporting plate 8, and at the same time, the cylinder 5 is started, and the telescopic rod of the cylinder 5 can pull the clamping plate 9 to move to one side of the supporting plate 8, so that the heating plate and the cutting knife between the clamping plate 9 and the supporting plate 8 can heat-seal the heat-sealing film.

[0026] The interior of the rear column 2 is hollow, and a connecting slide groove 11 connected to the interior of the rear column 2 is provided on the surface of one side of the rear column 2 facing the cylinder 5, and a connecting slide rod 12 is fixedly connected between the inner walls of the upper and lower sides of the connecting slide groove 11, and a connecting slide sleeve 13 is slidably sleeved on the outer surface of the connecting slide rod 12, one side of the connecting slide sleeve 13 extends out of the outer surface of the rear column 2, and the other side extends into the rear column 2, and a driving component for controlling the rotation of the rotating shaft 3 is provided on the side of the connecting slide sleeve 13 located in the rear column 2, and a sleeve plate 10 is slidably sleeved on the outer surface of the slide rod 7, and bolts are provided on the sleeve plate 10, and the sleeve plate 10 is fixedly installed on the slide rod 7 by bolts, and a first rotating plate 14 is hingedly connected to the connecting sleeve 13 on the surface of one side outside the rear column 2, and a second rotating plate 15 is hingedly connected to the surface of the sleeve plate 10 on the side facing the rear column 2, and the other side of the second rotating plate 15 slides through the first rotating plate 14, and the first rotating plate 14 is also provided with bolts, and the bolts can fix the second rotating plate 15 to the first rotating plate 14;

[0027] When the heat-sealing film is heat-sealed again, the telescopic rod of the cylinder 5 pushes the clamping plate 9 to move to the side away from the supporting plate 8, so that the sleeve plate 10 will form a thrust on the second rotating plate 15, and the first rotating plate 14 will synchronously push the connecting sliding sleeve 13 to move upward for a distance. At this time, the driving component controls the rotating shaft 3 to rotate clockwise, so that the heat-sealing film on the mounting shaft 4 is transported downward for a distance. When it is necessary to adjust the downward conveying distance of the heat-sealing film, it is only necessary to adjust the displacement of the sleeve plate 10 on the sliding rod 7. At the same time, the second rotating plate 15 also needs to adjust the contraction degree in the first rotating plate 14. When the sleeve plate 10 is adjusted to the side close to the rear plate 2, the distance that the first rotating plate 14 pushes the connecting sleeve 13 to move upward is shorter, and the rotation angle of the rotating shaft 3 is also smaller. When the sleeve plate 10 is adjusted to the side away from the rear plate 2, the distance that the first rotating plate 14 pushes the connecting sleeve 13 to move upward is longer, and the rotation angle of the rotating shaft 3 is also larger. Therefore, the length of the heat-sealing film conveying can be adjusted under the same operating steps, and is no longer limited to one length. It can be adjusted according to actual conditions, which further ensures the effect of the device in heat sealing the finished hexagonal boron nitride product.

[0028] The driving assembly includes a rack 16, which is fixedly mounted on one side of the connecting sleeve 13 located inside the rear column 2. The other side of the rack 16 is meshedly connected with a gear 18. The side of the gear 18 is fixedly connected with a gear shaft 17. The other end of the gear shaft 17 is rotatably connected to the inner wall of the rear column 2. Therefore, when the connecting sleeve 13 moves upward, the rack 16 can mesh with the transmission gear 18 and rotate in a clockwise direction.

[0029] An inner cavity 19 is provided in the gear 18, and one end of the rotating shaft 3 away from the mounting shaft 4 rotates and penetrates into the inner cavity 19, and a plurality of pushing plates 20 are fixedly connected to the annular inner wall of the inner cavity 19, and a hinge seat 21 is fixedly connected to the outer surface of the rotating shaft 3 located in the inner cavity 19, and a contact plate 22 is rotatably connected to the hinge seat 21, and the other side of the contact plate 22 contacts the pushing plate 20, and a torsion spring is provided between the contact plate 22 and the hinge seat 21, so that the contact plate 22 is vertical in the initial state under the action of the torsion spring, and an L-shaped gear lever 23 is fixedly connected to the rear side surface of the contact plate 22, and the lower end of the vertical rod of the L-shaped gear lever 23 contacts the outer surface of the rotating shaft 3, and the L-shaped gear lever 23 is provided on one side of the clockwise rotation direction of the contact plate 22;

[0030] When the gear 18 rotates clockwise, the push plate 20 rotates synchronously. Since the contact plate 22 is blocked by the L-shaped gear lever 23 and cannot rotate, the push plate 20 can drive the contact plate 22 to rotate synchronously, thereby synchronously driving the rotating shaft 3 to rotate clockwise. When the gear 18 rotates counterclockwise, the push plate 20 will form a thrust on the contact plate 22. Since the L-shaped gear lever 23 is arranged on one side of the clockwise rotation direction of the contact plate 22, it cannot limit the contact plate 22, so that the rotating shaft 3 will not rotate with the gear 18. The above structure is adopted to avoid the situation where the mounting shaft 4 rolls up the heat-sealing film when the splint 9 is heat-sealing the heat-sealing film, thereby further ensuring the stability of the device during operation.

[0031] The working principle of the automatic heat sealing device for hexagonal boron nitride finished products provided by the utility model is as follows: after the heat-sealed film is heat-sealed again, the telescopic rod of the cylinder 5 pushes the clamping plate 9 to move to the side away from the supporting plate 8, so that the sleeve plate 10 will form a thrust on the second rotating plate 15, and the first rotating plate 14 synchronously pushes the connecting sleeve 13 to move upward for a distance. At this time, the driving component controls the rotating shaft 3 to rotate clockwise, so that the heat-sealed film on the mounting shaft 4 is transported downward for a distance. When it is necessary to adjust the downward conveying distance of the heat-sealed film, it is only necessary to adjust the displacement of the sleeve plate 10 on the sliding rod 7, and the second rotating plate 15 also needs to adjust the contraction degree in the first rotating plate 14. When the sleeve plate 10 is adjusted to the side close to the rear plate 2, the distance that the first rotating plate 14 pushes the connecting sleeve 13 to move upward is shorter, and the rotation angle of the rotating shaft 3 is also reduced. When the sleeve plate 10 is adjusted to the side away from the rear plate 2, the distance that the first rotating plate 14 pushes the connecting sleeve 13 to move upward is longer, and the rotation angle of the rotating shaft 3 is also increased.
