Description

Technical Field

[0001] The utility model relates to a foaming board production technology, in particular to a foaming board extrusion molding device. Background Art

[0002] Foam board is a lightweight, porous sheet material, typically made from a foamable resin material, formed by heating and foaming. It offers advantages such as light weight, excellent thermal insulation, and good sound absorption, making it widely used in construction, furniture, electronics, and other fields.

[0003] During the production of foam board, the raw material particles and additives are first mixed at high temperature and high speed according to the process requirements. After reaching a certain temperature, the mixture is quickly placed in a cold mixing kettle to cool. Then, an extruder is used to extrude the material through the die, where foam is formed. After cooling and setting, the sheet is transferred by a haul-off machine to a cutting platform, where it is cut according to the required specifications to produce the foam board of the desired size.

[0004] Currently, most foam board extrusion systems utilize a screw extruder. Driven by the screw extruder and fed through a die at the output end, the raw material in the system is squeezed into a mold, where it is transferred via a conveyor belt to the next foam board. However, the raw material extruded by this extruder is not evenly distributed within the mold, and bubbles form within the raw material, leading to uneven distribution and poor foam board production quality. For these reasons, it is necessary to design a foam board extrusion system that can degas and disperse the extruded raw material, thereby improving the uniformity and quality of the foamed board. Utility Model Content

[0005] In view of the above problems existing in the prior art, the purpose of the present invention is to provide a foam board extrusion molding device, which can exhaust and disperse the extruded raw materials and increase the uniformity and quality of the foam board.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are described in more detail below in conjunction with the drawings of the embodiments. Note: The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0027] As attached Figure 1 To the attached Figure 4As shown, the foam board extrusion molding device provided by the embodiment of the utility model is used to extrude the raw materials and disperse the exhaust gas, thereby increasing the uniformity and manufacturing quality of the production template 13. In the production process of the foam board extrusion molding device, the existing foam board processing technology is applied, and the conveying roller 12 is the material moving structure of the machine body 1. During processing, multiple templates 13 will first be placed on the conveying roller 12 at the input end of the workbench 11. Through the rotation of the conveying roller 12, the multiple templates 13 are sequentially conveyed to the feeding end of the machine body 1. The raw materials are extruded from the die through the spiral extrusion device and can be squeezed into the template 13 for foaming reaction. After that, the next stage of cooling and solidification is carried out through the driving output of the conveying roller 12. In order to exhaust and evenly treat the raw materials in the template 13, an output rack 4 can be set at the output end of the workbench 11 as the discharge interval of the device, and a conveying seat 2 is set at the lower end of the template 13 to move the position of the template 13 on the conveying roller 12 and the output rack 4, which can also facilitate the uniform dispersion of the raw materials; then, a dispersion component 3 is set in the middle between the template 13 and the conveying seat 2. The template 13 is driven by the vibration of the dispersion component 3 to disperse the raw materials in the template 13, exhaust and evenly shake the raw materials in the interval of multiple conveying rollers 12, and then move to the interval of the output rack 4 to maintain the smooth output of the template 13, facilitate the transfer of the template 13, and provide favorable conditions for the solidification and cooling of the raw materials in the template. When the template 13 is in use, the conveyor base 2 at the bottom of the template 13 is placed on the upper side of multiple conveyor rollers 12. The rotation of the conveyor rollers 12 drives the template 13 toward the machine body 1. Through the cooperation of the output rack 4 and the conveyor rollers 12, and the driving inertia of the conveyor rollers 12, the template 13 can use the conveyor base 2 to move from the conveyor rollers 12 to the output rack 4, and the raw materials in the template 13 can be processed in different states. This facilitates the template 13 to vibrate the raw materials between the multiple conveyor racks 4, expelling gas from the raw materials and increasing the uniformity of the raw materials. When the template 13 moves to the output rack 4, the output rack 4 is used to slide out of the machine body 1, providing favorable conditions for the production of foamed boards.

[0028] It is worth noting that in some embodiments, such as those shown in Figures 5 and 6, the conveyor base 2 may include a buffer member 21 connected to the template 13 and a conveyor pad 22 disposed at the lower end of the buffer member 21. The conveyor pad 22 may be made of rubber. When the conveyor base 2 is placed on the conveyor rollers 12, the conveyor rollers 12 rotate and drive the conveyor base 2 and the upper template 13, moving the template 13 toward the machine body 1 to facilitate loading and feeding the template 13. The provision of the buffer member 21 facilitates increased stability in the movement of the template 13 between the multiple conveyor rollers 12, ensuring safe vibration and dispersion of the template 13, and improving the production efficiency of the template 13.

[0029] In some embodiments, as Figure 2 and 3As shown, to increase the reaction quality of the raw materials in the template 13, the output rack 4 is larger than the conveyor pad 22. Furthermore, the output rack 4 is positioned at the same height as the upper end of the conveyor roller 12. A transition portion 41 is provided on the lower side of the conveyor roller 12 at the end of the output rack 4 near the conveyor roller 12, facilitating the transfer of the template 13. When the template 13 is being processed on the workbench 11, this transition portion 41 allows it to smoothly move from the conveyor roller 12 to the output rack 4. This ensures smooth movement of the template 13 within the output rack 4, facilitates the stable solidification of the raw materials, and facilitates the transfer of the template 13.

[0030] Among them, it is worth mentioning that Figure 3 and 6 As shown, in order to ensure the smooth movement of the template 13 on the multiple conveying rollers 12 and increase the stability of the movement of the template 13 on the multiple conveying rollers 12, in some embodiments, the buffer member 21 includes a support plate 211 connected to the template 13, a positioning seat 212 is fixed on the support plate 211, and the positioning seat 212 can be made of rubber material. Then, a positioning sleeve 213 is set in the positioning seat 212, and a buffer spring 214 connected to the template 13 is fixed between the positioning sleeve 213 and the positioning seat 212, and rubber pads are provided at both ends of the buffer spring 214. When the buffer spring 214 is deformed by force, the positioning sleeve 213 can move linearly in the vertical direction in the positioning seat 212, and the elastic deformation of the rubber pad weakens the force on the buffer spring 214, thereby achieving stable movement of the conveying seat 2, preventing the template 13 from deflecting or falling, and increasing the safety of the extrusion molding device in producing foamed boards.

[0031] Among them, it is worth mentioning that Figure 5 As shown, the vibration-dispersing assembly 3 may include a vibration motor 32 fixed to the template 13, and a battery 31 arranged on one side of the vibration motor 32, and the battery 31 and the vibration motor 32 are both located in the middle of the bottom surface of the template 13. By applying the power work technology of the existing vibration motor 32, the vibration motor 32 can use the electricity in the battery 31 to vibrate the template 13, thereby discharging the gas in the raw material and shaking the raw material uniformly. In addition, when used in conjunction with the buffer 21, the extrusion molding device can not only discharge the gas in the raw material, but also ensure the uniform production of the foam board, realize the continuous production of the device, and improve the production efficiency of the device.

[0032] In order to further ensure the exhaust and vibration of the raw materials in the template 13, a limiting structure can be set on the body 1 to limit the exhaust and vibration intervals of the template 13, so as to achieve accurate injection of raw materials and stable movement of multiple conveying rollers 12. Figure 1 and 4As shown, two symmetrically distributed clamping plates 5 can be set at the input end of the body 1, and the clamping plates 5 include multiple elastic tubes 51 connected to the body 1 and a transition plate 53 and a horizontal plate 54 connected to the multiple elastic tubes 51. In addition, the transition plate 53 is opened outward at one end away from the body 1, and the horizontal plate 54 is distributed parallel to the body 1. The two outwardly opened transition plates 53 facilitate the guiding processing of the input template 13, so that the template 13 can be input into the body 1 in a straight line, and loaded and output after being limited by the horizontal plate 54.

[0033] Furthermore, to facilitate the movement of the template 13 on the multiple conveyor rollers 12 and to degas and disperse the raw materials, the elastic tube 51 may be made of silicone material and provided with a tubular spring 52 to increase the stability of the elastic tube 51 in limiting the transition plate 53. Furthermore, multiple rotating rollers 55 are rotatably provided on the horizontal plate 54 to provide a lubricating structure at the horizontal plate 54, allowing for quick movement to the output rack 4 and removal, facilitating the template 13's movement to the horizontal plate 54 and separation from the two clamping plates, providing favorable conditions for loading the next template 13 and improving the production efficiency of the device.

[0034] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
