Description

Technical Field

[0001] This utility model relates to the field of foam processing technology, and in particular to substrate-free foam bonding equipment. Background Technology

[0002] Substrate-free generally refers to materials and processes that do not rely on traditional substrates (such as paper, metal, plastic, etc.). Foam laminating equipment is used to bond foam materials with other materials (such as plastic, metal, paper, etc.), and is widely used in industries such as packaging, automotive, electronics, furniture, and construction.

[0003] In existing technologies, some equipment, when processing foam materials, causes material breakage and tearing due to tensile force, especially when processing foams with uneven thickness or high flexibility, where the impact of tensile force is more pronounced. This not only increases production costs and reduces production efficiency, but also, in some high-precision applications, errors caused by tensile force prevent products from meeting design standards. Therefore, a substrate-free foam lamination device is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a substrate-free foam bonding device, which aims to improve the problem of excessive tension in some existing devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A substrate-free foam laminating device includes a support frame, an externally fixedly connected suction conveyor belt, a centrally controlled lightweight pressure roller fixedly connected to the top of the suction conveyor belt, a pressing device fixedly connected to the top of the suction conveyor belt, an externally fixedly connected movable clamping belt, multiple feeding rollers (first and second) fixedly connected to the top of the support frame, multiple receiving rollers fixedly connected to the top of the support frame, and two sliding components providing left and right movement force fixedly connected to the external sides of the centrally controlled lightweight pressure roller.

[0007] As a further description of the above technical solution:

[0008] The sliding assembly includes a linear guide rail, which is fixedly connected to the outside of the central control lightweight pressure roller, and a slider is slidably connected to the outside of the linear guide rail.

[0009] As a further description of the above technical solution:

[0010] The slider is externally fixed to a fixed post, and a movable ball is rotatably connected to the inside of the fixed post.

[0011] As a further description of the above technical solution:

[0012] The movable ball is fixedly connected to a connecting post, and the connecting post is fixedly connected to a storage box.

[0013] As a further description of the above technical solution:

[0014] The top of the storage box is fixedly connected to an inlet, and the inside of the connecting column is fixedly connected to a transport column.

[0015] As a further description of the above technical solution:

[0016] A cleaning sponge is fixedly connected to the outside of the storage box, and the inside of the cleaning sponge is fixedly connected to the outside of the transport column.

[0017] As a further description of the above technical solution:

[0018] The transport column is externally slidably connected to the outside of the central control lightweight pressure roller, and the central control lightweight pressure roller is externally slidably connected to the outside of the fixed column.

[0019] As a further description of the above technical solution:

[0020] The bottom of the support frame is fixedly connected to multiple wheels, and the bottom of the support frame is fixedly connected to a support column.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the suction adsorbs the material to fix it, the movable card limits the range, and the conveyor belt drives the movement of the substrate-free foam, so that it moves forward with the conveyor belt and adheres to the double-sided adhesive without being pulled. Thus, the material feeding process is basically without tension, eliminating the stretching and deformation of the material caused by tension.

[0023] 2. In this utility model, the slider slides upward by activating the linear guide rail. When it slides to the central control lightweight pressure roller, the cleaning sponge is squeezed and tilted under the pressure. Because there is a movable ball and connecting column at the rear, the cleaning sponge is not damaged. Furthermore, the pressure roller rotates outside the cleaning sponge, squeezing and rotating it, thus achieving the cleaning effect of the pressure roller. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 3This utility model provides an embodiment of a substrate-free foam bonding device, including a support frame 1. The support frame 1 is the main frame of the entire substrate-free foam bonding device, a three-dimensional structure made of metal, welded from high-strength steel. A suction conveyor belt 2 is fixedly connected to the outside of the support frame 1. The suction conveyor belt 2 is a specially designed conveyor belt with a main body of an annular plastic material, possessing good flexibility and wear resistance. A central control lightweight pressure roller 3 is fixedly connected to the top of the suction conveyor belt 2. The central control lightweight pressure roller 3 is made of lightweight metal material, such as aluminum alloy, which reduces the weight of the pressure roller while ensuring a certain strength. A pressing device 4 is fixedly connected to the top of the suction conveyor belt 2. The pressing device 4 is a key component for bonding substrate-free foam, and its outer shell is made of metal material, such as stainless steel, to ensure the strength and stability of the device. A movable clamp is fixedly connected to the outside of the support frame 1. Belt 5, the movable conveyor belt 5, is a component used to assist in material conveying and positioning. It is made of high-strength plastic belt material and is long and strip-shaped. Multiple feeding rollers 6, 7, and 8 are fixedly connected to the top of the support frame 1. The feeding rollers 6, 7, and 8 are all cylindrical roller structures made of metal, such as stainless steel. Two sliding components that provide left and right movement force are fixedly connected to the outer sides of the central control lightweight pressure roller 3. The sliding components include linear guide rails 9, which are long and strip-shaped metal guide rails made of high-strength alloy steel and are rectangular in shape. The linear guide rails 9 are fixedly connected to the outside of the central control lightweight pressure roller 3. A slider 10 is slidably connected to the outside of the linear guide rails 9. The slider 10 is a block structure that matches the linear guide rails 9 and is made of metal, such as aluminum alloy.

[0032] Reference Figure 3 , Figure 4The slider 10 is externally fixedly connected to a fixed post 11, which is a cylindrical metal rod made of high-strength alloy steel. A movable ball 12 is rotatably connected inside the fixed post 11. The movable ball 12 is a spherical metal component with a smooth surface, capable of free rotation within the fixed post 11. A connecting post 13 is externally fixedly connected to the movable ball 12. The connecting post 13 is a cylindrical metal rod with similar material and dimensions to the fixed post 11. A storage box 14 is externally fixedly connected to the connecting post 13. The storage box 14 is a container for storing cleaning fluid, cylindrical in shape and made of plastic. A filling port 15 is fixedly connected to the top of the storage box 14. The filling port 15 is a circular opening located at the top of the storage box 14, surrounded by a sealing device to prevent material leakage. A transport post 17 is internally fixedly connected to the connecting post 13. A cleaning sponge 16 is fixedly connected to the outside of the storage box 14. The cleaning sponge 16 is a porous sponge-like material with good water absorption and flexibility, which can clean the dust on the storage box 14. The cleaning sponge 16 is fixedly connected to the outside of the transport column 17. The outside of the transport column 17 is slidably connected to the outside of the central control lightweight pressure roller 3. The outside of the central control lightweight pressure roller 3 is slidably connected to the outside of the fixed column 11. Multiple wheels 18 are fixedly connected to the bottom of the support frame 1. The wheels 18 are circular rolling parts installed at the bottom of the support frame 1. They are made of rubber tires, have good elasticity and wear resistance, and can roll smoothly on the ground, reducing vibration when the equipment moves. A support column 19 is fixedly connected to the bottom of the support frame 1. The support column 19 is a cylindrical metal column made of high-strength alloy steel to prevent the equipment from shaking and moving during operation.

[0033] Working Principle: First, after the equipment is started, the suction conveyor belt 2 begins to run, transporting the foam material to be laminated to the working area of ​​the laminating equipment 4. The special design of the suction conveyor belt 2 allows it to firmly clamp the foam during transport, preventing material movement and deformation. As the foam material advances, the centrally controlled lightweight pressure roller 3 applies appropriate pressure through its lightweight structure, ensuring a tight bond between the foam material and the substrate. The laminating equipment 4 performs a uniform lamination process on the foam, ensuring the stability and consistency of the lamination effect.

[0034] Furthermore, the cleaning fluid in the storage box 14, through the cooperation of the connecting column 13 and the transport column 17, can be replenished to the cleaning sponge 16 in a timely manner, ensuring that it remains clean at all times to prevent dust and impurities from affecting the bonding quality. During equipment operation, the cleaning sponge 16 can effectively clean dust from the surface of the foam material, ensuring the cleanliness of the bonding surface.

[0035] Finally, the laminated foam material is smoothly conveyed to subsequent processes and packaging stages via the cooperation of feed roller 6, feed roller 7, and take-up roller 8. The entire equipment's design and process optimization ensure that the foam material is free from stretching and deformation caused by tension during the feeding process. Furthermore, because there is no tension throughout the process, the laminated material will not shrink during secondary processing due to prolonged storage, preventing defective finished products. The conveyor-type lamination method is independent of human factors and saves time compared to traditional tension adjustment methods, thus improving efficiency.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
