Description

Technical Field

[0001] The utility model relates to the technical field of automatic laminators, in particular to a fully automatic laminator for products. Background Art

[0002] The plastic sealing process is to use a polyester film coated with hot melt adhesive to bond the sealed items to the plastic film through the processing of the plastic sealing machine. Since the processing is carried out under a certain pressure and high temperature, and uses high-quality polyester film and hot melt adhesive with good transparency, it can not only ensure that the plastic sealed items are not damaged at room temperature, but also increase the visual effect of the items. In this process, the technical performance of the plastic sealing machine is the key to ensuring the quality of plastic sealing.

[0003] In the prior art, a fully automatic laminator proposed by announcement number CN218704223U includes a base, a laminator assembly fixedly connected to the top of the base, and a feed assembly installed at one end of the top of the base; the feed assembly includes a No. 1 conveyor, a fixed frame installed at one end of the No. 1 conveyor, a No. 1 electric push rod fixedly connected to the top of one side of the fixed frame, a movable part fixedly connected to the telescopic end of the No. 1 electric push rod, and a No. 2 electric push rod fixedly connected to the inside of the fixed frame. The utility model, through the provision of the feed assembly, allows workers to place rectangular objects on the No. 1 conveyor, and the rectangular objects can be stacked instead of being placed one by one. This method saves human resources. Since the objects can be stacked, but the laminator assembly is still processed individually, the correlation between the laminator's working efficiency and the worker's placement speed is reduced, thereby improving the working efficiency of the fully automatic laminator.

[0004] When in use, this application can push stackable rectangular items into the laminator for laminating through the cooperation of electric push rod No. 1 and electric push rod No. 2, thereby reducing the correlation between the speed of item placement and workers, and thereby improving the efficiency of the automatic laminator. However, this application requires reciprocating control of electric push rod No. 1 and electric push rod No. 2, which takes a certain amount of time. The time to push the items to be laminated to the laminator is prolonged, which easily affects the laminating efficiency of the laminator. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a fully automatic product laminating machine so as to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A fully automatic product laminating machine comprises a base frame, a laminating mechanism is provided on the base frame, a feeding support is fixedly connected to the end of the base frame, a feeding bracket is fixedly connected to the top side of the feeding bracket, a conveying mechanism is provided on the feeding bracket, and a limiting mechanism is provided on the feeding bracket;

[0008] The conveying mechanism includes a hydraulic cylinder, a splint, a rotating shaft, an airbag cover and a driving motor. The hydraulic cylinder is fixedly installed on the top of the feeding bracket, and the output end of the hydraulic cylinder extends into the feeding bracket. The splint is fixedly installed on the output end of the hydraulic cylinder, and the rotating shaft is rotatably installed in the splint. The airbag cover is fixedly installed on the outer peripheral side of the rotating shaft, and the airbag cover completely wraps the circumferential side of the rotating shaft. A gap is left between the outer peripheral side of the airbag cover and the top side of the feeding support. The driving motor is fixedly installed on the outer end of the splint, and the output end of the driving motor is drivingly connected to the end of the rotating shaft.

[0009] In a preferred example, the present invention can be further configured as follows: the limiting mechanism includes a limiting groove, the limiting groove is opened on the top side of the feeding support, a supporting plate is slidably connected in the limiting groove, a reset groove is opened on the bottom side of the limiting groove, a reset spring is fixedly connected to the bottom side wall of the reset groove, the top end of the reset spring is fixedly connected to an insertion rod, and the top end of the insertion rod is fixedly connected to the supporting plate.

[0010] In a preferred example, the present invention can be further configured as follows: the length of the rotating shaft is greater than the length of the supporting plate, and a plurality of protrusions are fixedly connected to the outer peripheral side of the airbag cover.

[0011] In a preferred example, the present invention can be further configured as follows: a positioning groove is opened in the limiting groove on a side away from the plastic sealing mechanism, an electromagnetic lock is provided in the positioning groove, and a suction plate is inserted into and fixedly connected to the side of the supporting plate close to the electromagnetic lock.

[0012] In a preferred example, the present invention can be further configured as follows: the feeding bracket is J-shaped, and a gap is left between the end of the feeding bracket and the top side of the feeding support.

[0013] In a preferred example, the present invention can be further configured as follows: the top side of the feeding support is aligned with the top side of the base frame.

[0014] In summary, the present invention has at least one of the following beneficial technical effects:

[0015] 1. This fully automatic laminator ensures that the outer periphery of the airbag cover is always in contact with the product being conveyed. The drive motor continuously rotates the airbag cover, eliminating the need to repeatedly control the conveying mechanism for adjustment and conveying. Furthermore, the machine can automatically limit the conveying of stacked products, ensuring that each product is conveyed individually. This reduces product pushing time and improves laminating efficiency.

[0016] 2. This fully automatic laminator is designed for products that are stacked and moved horizontally onto the carrier plate. After the bottom portion of the product has been moved onto the carrier plate, the carrier plate is subjected to a certain amount of pressure, causing it to be pushed down and moved. This can easily cause the stacked products to tilt or even collapse. Therefore, an electromagnetic lock can be set up to absorb the suction plate and thus limit the carrier plate. After the stacked products are completely moved onto the carrier plate, the electromagnetic lock can be opened, allowing the stacked products to enter the limited slot and prevent the stacked products from tilting or collapsing.

[0017] 3. This fully automatic laminator has a J-shaped feed bracket, and a gap is left between the end of the feed bracket and the top side of the feed support, so that the transport mechanism can transport the stacked products to the carrier plate, providing appropriate space for the transport mechanism to transport the stacked products.

DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1-Figure 3 The utility model discloses a fully automatic laminating machine, comprising a base frame 1, a laminating mechanism 2 being provided on the base frame 1, a feeding support 3 being fixedly connected to the end of the base frame 1, a feeding bracket 4 being fixedly connected to the top side of the feeding bracket 3, a conveying mechanism 5 being provided on the feeding bracket 4, and a limiting mechanism 6 being provided on the feeding bracket 4;

[0026] The conveying mechanism 5 includes a hydraulic cylinder 7, a splint 8, a rotating shaft 9, an airbag cover 10 and a drive motor 11. The hydraulic cylinder 7 is fixedly installed on the top of the feeding bracket 4, and the output end of the hydraulic cylinder 7 extends into the feeding bracket 4. The splint 8 is fixedly installed on the output end of the hydraulic cylinder 7. The rotating shaft 9 is rotatably installed in the splint 8. The airbag cover 10 is fixedly installed on the outer peripheral side of the rotating shaft 9, and the airbag cover 10 completely wraps the circumferential side of the rotating shaft 9. A gap is left between the outer peripheral side of the airbag cover 10 and the top side of the feeding support 3. The drive motor 11 is fixedly installed on the outer end of the splint 8, and the output end of the drive motor 11 is drivingly connected to the end of the rotating shaft 9.

[0027] In this embodiment, when in use, the stacked products are transported to the feeding support 3 by the transport mechanism, and then the stacked products are limited by the limiting mechanism 6. At this time, the hydraulic cylinder 7 is started, so that the hydraulic cylinder 7 drives the splint 8 to move downward, and then drives the rotating shaft 9 and the airbag cover 10 to move downward until the airbag cover 10 is pressed down to the product at the top. Then the drive motor 11 is started, and the drive motor 11 will drive the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it will also drive the airbag cover 10 to rotate. The airbag cover 10 is made of rubber or silicone material. At the same time, the airbag cover 10 will deform after being squeezed by the product, thereby increasing the friction between the airbag cover 10 and the product, so that when the airbag cover 10 rotates, the friction between the product and the airbag cover 10 drives the product to be pushed to the plastic sealing mechanism 2 for plastic sealing. The limiting mechanism 6 is set to limit the stacked products, so that the product conveyed each time is always single, and after the top product is conveyed out, the lower product is automatically pushed to the airbag cover 10 by the limiting member, so as to facilitate continuous conveying of products for plastic sealing.

[0028] In a further preferred embodiment of the present invention, Figure 1-3As shown, the limiting mechanism 6 includes a limiting groove 12, which is opened on the top side of the feeding support 3, and a supporting plate 13 is slidably connected in the limiting groove 12. A reset groove 14 is opened on the bottom side of the limiting groove 12, and a reset spring 15 is fixedly connected to the bottom side wall of the reset groove 14. The top of the reset spring 15 is fixedly connected to the insertion rod 16, and the top of the insertion rod 16 is fixedly connected to the supporting plate 13.

[0029] In this embodiment, the limiting groove 12 can be used for the supporting plate 13 to slide up and down inside. In the initial state, the top side of the supporting plate 13 is aligned with the top side of the feeding support 3. Then, after the stacked products are transported to the top side of the supporting plate 13, the supporting plate 13 will be pressed down, and the insertion rod 16 will also be pressed down, so that the insertion rod 16 enters the reset groove 14 and squeezes the spring. When the product at the top is transported for plastic sealing, the pressure on the spring is reduced, and it will be pulled back by the force, thereby driving the supporting plate 13 to move upward. At the same time, when the product is transported, the remaining products are limited by the inner side wall of the limiting groove 12 to prevent the remaining products from following the plastic sealing mechanism 2 and affecting the plastic sealing of the product by the plastic sealing mechanism 2.

[0030] In addition, if the spring rebounds and drives more than one product over the inner wall of the limiting groove 12, the hydraulic cylinder 7 can be used to drive the clamping plate 8 to press down, so that the distance between the squeezed airbag cover 10 and the top side of the feeding support 3 is only sufficient for transporting a single product.

[0031] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the length of the rotating shaft 9 is greater than the length of the supporting plate 13 , and a number of protrusions 17 are fixedly connected to the outer peripheral side of the airbag cover 10 .

[0032] In this embodiment, the length of the rotating shaft 9 is greater than the length of the supporting plate 13, so that the contact area between the airbag cover 10 and the product is maximized. At the same time, the plurality of protrusions 17 are pressed against the product, thereby increasing the friction between the airbag cover 10 and the product, and further improving the stability of the airbag cover 10 when conveying the product.

[0033] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a positioning groove 18 is provided in the limiting groove 12 on a side away from the plastic sealing mechanism 2 , an electromagnetic lock 19 is provided in the positioning groove 18 , and a suction plate 20 is inserted and fixedly connected to the side of the carrying plate 13 close to the electromagnetic lock 19 .

[0034] In this embodiment, since the stacked products are moved horizontally onto the supporting plate 13, after the part of the product located at the bottom has moved onto the supporting plate 13, the supporting plate 13 will be subjected to a certain pressure and thus pressed downward. At this time, the stacked products are prone to tilting or even collapsing. Therefore, the electromagnetic lock 19 can be set to adsorb the suction plate 20 to limit the supporting plate 13. After the stacked products are completely moved onto the supporting plate 13, the electromagnetic lock 19 can be opened to facilitate the stacked products to enter the limiting groove 12, thereby preventing the stacked products from tilting and collapsing.

[0035] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the feeding bracket 4 is J-shaped, and a gap is left between the end of the feeding bracket 4 and the top side of the feeding support 3.

[0036] In this embodiment, the feeding bracket 4 is J-shaped, and a gap is left between the end of the feeding bracket 4 and the top side of the feeding support 3, so that the transportation mechanism can transport the stacked products to the supporting plate 13, providing appropriate space for the transportation mechanism to transport the stacked products.

[0037] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the top side of the feed support 3 is aligned with the top side of the base frame 1 .

[0038] In this embodiment, the top side of the feeding support 3 is aligned with the top side of the base frame 1, so that the top side of the feeding support 3 is aligned with the top side of the transportation mechanism on the plastic sealing mechanism 2, thereby avoiding the jamming phenomenon caused by the difference in height between the two places when the product is transported to the plastic sealing mechanism 2, thereby affecting the plastic sealing work of the product.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
