Description

Technical Field

[0001] This application relates to the field of lamination technology, and more specifically, to a sponge lamination machine. Background Technology

[0002] A sponge laminating machine is a device used to laminate sponges with thin films. It primarily uses processes such as heating and pressing to attach films like PE and PVC to the sponge surface, forming a protective composite layer. This improves the sponge's waterproof and abrasion-resistant properties, enhances its surface texture, and is commonly used in the processing of sponge products in furniture, packaging, and other fields. It automates the laminating process, improving production efficiency and product quality.

[0003] In practice, traditional sponge laminating machines have difficulty adjusting the pressing distance to accommodate sponges and films of different thicknesses. Furthermore, the heating and extrusion processes are not synchronized, which can easily lead to uneven melting of the adhesive layer, resulting in bubbles, poor adhesion, and other issues that affect the lamination quality and product consistency.

[0004] In view of this, this application proposes a sponge coating machine. Utility Model Content

[0005] The purpose of this application is to provide a sponge coating machine that solves the technical problems mentioned in the background art.

[0006] This application provides a sponge laminating machine, including a worktable, an installation groove on the upper surface of the worktable, and a laminating mechanism above the worktable;

[0007] The coating mechanism includes a fixed cylinder located above the workbench, an extrusion cylinder below the fixed cylinder, an electric heating cylinder fixedly connected to the outer wall of the extrusion cylinder, a conveying cylinder inside the mounting groove, a pair of fixing strips on one side below the fixed cylinder, and the fixing strips are fixedly connected to a fixing plate. A brush strip is fixedly connected to one side of the two fixing strips that are close to each other's end faces, and a silicone strip is fixedly connected to the other side of the two fixing strips that are close to each other's end faces.

[0008] Optionally, a fixing plate is fixedly connected to one side of the workbench, a sliding groove is opened through the inside of the fixing plate, and a fixing frame is fixedly connected to the side wall of the fixing plate.

[0009] Optionally, rotating rods are fixedly inserted inside the fixed cylinder, extrusion cylinder, and conveying cylinder, and one end of each rotating rod passes through the fixed plate.

[0010] Optionally, the fixing frame has a first bearing ring inside, a second bearing ring below the first bearing ring, and an electric telescopic rod is fixedly connected between the outer walls of the first bearing ring and the second bearing ring.

[0011] Optionally, one end of the rotating rod inside the fixed cylinder extends into the first bearing ring and is fixedly connected to the inner ring of the first bearing ring; another end of the rotating rod inside the extrusion cylinder passes through the slide groove and extends into the interior of the second bearing ring, and is fixedly connected to the inner ring of the second bearing ring.

[0012] Optionally, a motor is fixedly connected to the lower part of the side wall of the fixed frame, and the output end of the motor is fixedly connected to one end of the rotating rod inside the conveying cylinder.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0014] This application utilizes an electric telescopic rod to adjust the downward pressing distance of the extrusion cylinder, accommodating sponges and sponge films of varying thicknesses and enhancing the device's versatility. Upon activation of the heating cylinder, heat is evenly transferred to the sponge film adhesive layer, causing it to melt rapidly and adhere tightly to the sponge surface, ensuring bonding strength and preventing air bubbles or detachment. A motor-driven conveyor cylinder rotates, propelling the sponge forward. Simultaneously, the extrusion cylinder and heating cylinder rotate with the sponge, creating synchronized pressing and conveying, ensuring a smooth and even adhesion between the sponge film and the sponge, and improving coating uniformity.

[0015] When the sponge film passes through the brush strip, the surface dust is effectively brushed off, preventing impurities from affecting the bonding quality, ensuring the cleanliness of the coated surface, and improving the finished product qualification rate. The sponge film then passes through the silicone strip, which increases friction to keep the sponge film taut, preventing loosening or wrinkles during transportation, and ensuring coating accuracy and aesthetics.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-3 This application provides a sponge laminating machine, including a worktable 1. An installation groove 2 is formed on the upper surface of the worktable 1, and a laminating mechanism 5 is located above the worktable 1. The laminating mechanism 5 includes a fixed cylinder 501 located above the worktable 1, an extrusion cylinder 502 located below the fixed cylinder 501, and an electric heating cylinder 503 fixedly connected to the outer wall of the extrusion cylinder 502. A conveying cylinder 504 is located inside the installation groove 2, and a pair of fixing strips 506 are provided on one side below the fixed cylinder 501, and the fixing strips 506 are fixedly connected to a fixing plate 3. Two fixing strips 506 are each fixedly connected to a brush strip 507 on one side of their respective end faces, and two fixing strips 506 are each fixedly connected to a silicone strip 508 on the other side of their respective end faces. When the sponge film passes through the brush strip 507, the surface dust is effectively brushed off, preventing impurities from affecting the bonding quality, ensuring the cleanliness of the coated surface, and improving the finished product qualification rate. The sponge film then passes through the silicone strip 508, and the silicone strip 508 increases friction to keep the sponge film in a taut state, preventing loosening or wrinkling during transportation, and ensuring the coating accuracy and aesthetics.

[0022] A fixed plate 3 is fixedly connected to one side of the workbench 1. A sliding groove 6 is opened through the inside of the fixed plate 3. A fixed frame 7 is fixedly connected to the side wall of the fixed plate 3. Rotating rods 505 are fixedly inserted into the inside of the fixed cylinder 501, the extrusion cylinder 502 and the conveying cylinder 504. One end of each of the multiple rotating rods 505 passes through the fixed plate 3. A motor 4 is fixedly connected to the lower side wall of the fixed frame 7. The output end of the motor 4 is fixedly connected to one end of the rotating rod 505 inside the conveying cylinder 504. The sliding groove 6 plays a good limiting role, making the movement of the extrusion cylinder 502 and the rotating rod 505 inside the extrusion cylinder 502 more stable.

[0023] The fixed frame 7 has a first bearing ring 509 inside, and a second bearing ring 510 below the first bearing ring 509. An electric telescopic rod 511 is fixedly connected between the outer walls of the first bearing ring 509 and the second bearing ring 510. One end of the rotating rod 505 inside the fixed cylinder 501 extends into the first bearing ring 509 and is fixedly connected to the inner ring of the first bearing ring 509. One end of the rotating rod 505 inside the extrusion cylinder 502 passes through the slide groove 6 and extends into the interior of the second bearing ring 510 and is fixedly connected to the inner ring of the second bearing ring 510. The downward pressing distance of the extrusion cylinder 502 can be adjusted by the electric telescopic rod 511 to adapt to sponges and sponge films of different thicknesses, thereby improving the versatility of the device. After the electric heating cylinder 503 is started, the heat is evenly conducted to the sponge film adhesive layer, which melts quickly and adheres tightly to the sponge surface, ensuring the bonding strength and avoiding bubbles or detachment. Motor 4 drives the conveyor cylinder 504 to rotate and push the sponge to move. At the same time, the extrusion cylinder 502 and the electric heating cylinder 503 rotate with the movement of the sponge, forming a synchronous pressing and conveying, which ensures that the sponge film and the sponge are flat and improves the uniformity of film coating.

[0024] Working principle: The sponge film roll is fitted onto the fixing cylinder 501. The sponge film is pulled out of the roll, and one end of the sponge film passes through the brush strip 507 and silicone strip 508 between the two fixing strips 506, moving to the bottom of the extrusion cylinder 502. The worker places the sponge to be coated onto the workbench 1 and starts the electric telescopic rod 511. The telescopic end of the electric telescopic rod 511 moves downward, causing the second bearing ring 510 to move downward. The movement of the second bearing ring 510 causes the rotating rod 505 inside the extrusion cylinder 502 to move downward inside the slide groove 6 until the electric heating cylinder 503 on the extrusion cylinder 502 presses the sponge film onto the sponge. Start the heating cylinder 503 and motor 4. The heating cylinder 503 releases heat and heats the sponge film, melting the adhesive layer of the sponge film and adhering it to the sponge. The motor 4 drives the output end to rotate, which in turn drives the rotating rod 505 inside the conveying cylinder 504 to rotate. The rotating rod 505 drives the conveying cylinder 504 to rotate, which in turn pushes the sponge to move. The movement of the sponge pulls the sponge film and drives the extrusion cylinder 502 and the heating cylinder 503 to rotate. The heating cylinder 503 continuously presses the sponge and sponge film. The movement of the sponge film drives the fixed cylinder 501 to rotate. The fixed cylinder 501 rotates and continuously feeds the sponge film through the brush strip 507 and silicone strip 508. The brush strip 507 brushes off the dust on the surface of the moving sponge film to prevent dust from entering the adhesive layer and affecting the adhesion effect with the sponge. The silicone strip 508 increases friction, keeping the sponge film taut during conveying. After the sponge is coated, turn off all electrical appliances, cut the sponge film, and remove the sponge.
