Description

Technical Field

[0001] The invention relates to the field of extruded board production, in particular to a foaming device for XPS extruded boards. Background Art

[0002] As is well known, XPS (Extruded Polystyrene) extruded board is a lightweight, high-strength, low-thermal-conductivity, and waterproof insulation material widely used in construction, refrigeration, transportation, and other fields. Its production process involves the use of a foaming device. Existing foaming devices typically undergo the following steps before use: (1) Mold cleaning: Before each production, the inner wall of the mold must be thoroughly cleaned to remove the foaming agent, foam and other impurities remaining in the previous production process.

[0003] (2) Mold drying: After cleaning, the inner wall of the mold must be completely dry to ensure that the subsequent foaming process will not affect the quality and performance of the foam due to residual moisture.

[0004] (3) Coating of release agent: In order to ensure that the foamed product can be demoulded smoothly, the inner wall of the mold needs to be coated with a release agent.

[0005] However, the existing foaming device involves a wide range of equipment in the cleaning, drying and release agent coating processes before use. That is, each process requires specific equipment to implement, such as using a cleaning machine for cleaning, a dryer for drying, and finally spraying the release agent through a spraying device. This not only leads to a decrease in production efficiency, but may also affect the quality and performance of the final product. In addition, each process requires independent equipment to handle, which increases the complexity of the entire production system. Summary of the Invention

[0021] The following description is merely illustrative in nature and is not intended to limit the present disclosure, its applications, or uses. It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure. Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0022] Example 1 like Figures 1-11 As shown: This embodiment provides a technical solution: a foaming device for XPS extruded board, which is used in the production process of XPS extruded board to shape and foam the extruded material of the extruder, including a foaming mold 1, the foaming mold 1 includes a lower mold body 11 in a fixed position and an upper mold body 10 that can move up and down, and a cleaning and coating integrated mechanism 2 is provided on the side of the foaming mold 1. The cleaning and coating integrated mechanism 2 is installed above the lower mold body 11 through a support control mechanism 3. The cleaning and coating integrated mechanism 2 can move between the upper mold body 10 and the lower mold body 11 under the control and drive of the support control mechanism 3, and clean, dry and spray the release agent on the inner walls of the upper mold body 10 and the lower mold body 11. It should be noted that the upper mold body 10 has a channel that can guide the extruded material of the extruder to flow into the upper mold body 10 and the lower mold body 11 for shaping and foaming, and the channel can be connected to the discharge port of the extruder.

[0023] Specifically, such as Figure 3 As shown, in order to realize that the cleaning and coating integrated mechanism 2 can clean, dry and spray the inner wall of the upper mold body 10 and the lower mold body 11 in an integrated manner, in this embodiment, the cleaning and coating integrated mechanism 2 includes a main pipe 21, a functional pipe group 22 and a second motor 23, wherein three guide flow channels are provided inside the main pipe 21, namely, a drying gas flow channel 210, a cleaning liquid flow channel 211 and a release agent flow channel 212; The functional pipe group 22 includes a drying gas pipeline 221, a cleaning liquid pipeline 222, and a release agent pipeline 223. The drying gas pipeline 221, the cleaning liquid pipeline 222, and the release agent pipeline 223 are respectively connected to the drying gas flow channel 210, the cleaning liquid flow channel 211, and the release agent flow channel 212 in the main pipe 21. A plurality of nozzles 220 are evenly installed on the drying gas pipeline 221, the cleaning liquid pipeline 222, and the release agent pipeline 223. It should be noted that the drying gas pipeline 221, the cleaning liquid pipeline 222, and the release agent pipeline 223 all adopt a U-shaped structure, and the nozzles 220 are located on the outside of the U-shaped structure. Therefore, when the main pipe 21 rotates, the nozzles 220 can respectively correspond to the inner wall of the cavity 15 from a predetermined distance. In this way, whether it is cleaning or subsequent spraying of the release agent, it can achieve the effect of comprehensive cleaning and spraying the release agent without dead angles. The output shaft of the second motor 23 is connected to one end of the main pipe 21, so that it can control the rotation of the functional pipe group 22 and adjust the position of each pipe in the functional pipe group 22, thereby realizing the integrated cleaning, drying and spraying of the inner wall of the upper mold body 10 and the lower mold body 11. The working principle is: before the device foams, it is necessary to apply the mold release agent to the cavity 15 inside the upper mold body 10 and the lower mold body 11, and before applying the mold release agent, it is necessary to clean the inside of the cavity 15 to achieve the effect of ensuring the molding quality of the foamed product in the later stage. When the device is in use, the dry gas flow channel 210, the cleaning liquid flow channel 211 and the release agent flow channel 212 in the main pipe 21 are first connected to the external equipment respectively, and the external equipment is used to respectively clean the cavity 15 and the lower mold body 11. Drying gas, cleaning liquid and releasing agent are supplied to the drying gas flow channel 210, the cleaning liquid flow channel 211 and the releasing agent flow channel 212, and then the functional tube group 22 is controlled by the support control mechanism 3 to move in the upper mold body 10 and the lower mold body 11 (at this time, the upper mold body 10 and the lower mold body 11 are in a separated state, and the gap between the upper mold body 10 and the lower mold body 11 can allow the functional tube group 22 to move). During the movement, the cleaning liquid pipeline 222, the drying gas pipeline 221, and the releasing agent pipeline 223 are respectively controlled by the second motor 23 to be parallel to the inner wall of the cavity 15 in turn, thereby achieving the effect of cleaning first, then drying, and then coating. This not only reduces the tedious process of spraying the releasing agent, but also improves the processing efficiency.

[0024] Specifically, such as Figure 5-Figure 7As shown, since the main pipe 21 needs to be rotated during use to achieve the effect of adjusting each pipeline, the pipeline connected to the main pipe 21 from the outside needs to be a hose. This causes the hose to easily become tangled and messy during the rotation and movement of the main pipe 21. In order to solve this problem, in this embodiment, a control pipe assembly 20 is provided at the position of the main pipe 21 on the foaming mold. The control pipe assembly 20 includes a accommodating shell 204 with a circular structure and two side panels 201 installed parallel to both sides of the accommodating shell 204. Three delivery hoses 205 are connected to the main pipe 21, each delivery hose 205 corresponds to a diversion channel, and the connection position of the delivery hose 205 is located inside the accommodating shell 204. Such a structural arrangement ensures that during the movement and rotation of the main pipe 21, the part pulled by the delivery hose 205 is always located inside the accommodating shell 204, and does not cross-affect the pipeline outside the accommodating shell 204.

[0025] Specifically, such as Figure 5-Figure 7 As shown, in order to prevent the part pulled by the delivery hose 205 from interlacing inside the accommodating shell 204, thereby affecting the rotation of the main pipe 21, in this embodiment, two movable shafts 203 and two fixed shafts 202 are provided at the corresponding position of each delivery hose 205 inside the accommodating shell 204, wherein the two movable shafts 203 are symmetrically installed and can move under external constraints, and the two fixed shafts 202 are installed in parallel. The delivery hose 205 passes around the top of the two movable shafts 203 and then passes through between the two fixed shafts 202 to the outside of the accommodating shell 204. Such a structural arrangement ensures that when the main pipe 21 rotates, although the position of each delivery hose 205 will still change, its moving position is always limited by the movable shaft 203 and the fixed shaft 202, so there will be no mutual interlacing, thereby ensuring the stable operation of the equipment.

[0026] It should be noted that although the delivery hose 205 is a hose, it needs to have a certain hardness to ensure the delivery effect due to the need to transport the medium, and some delivery hoses 205 also need to be equipped with a heating structure to prevent the medium from cooling. Therefore, when the delivery hose 205 is staggered, it is easy for it to get stuck inside the accommodating shell 204.

[0027] Specifically, such as Figure 5-Figure 7As shown, since the main pipe 21 needs to rotate in two directions when rotating, the pipeline installation cannot achieve continuous rotation in one direction, so the delivery hose 205 will bend and stretch. In order to ensure that the delivery hose 205 can cope with this situation and keep the delivery hose 205 in a tensioned state at all times, in this embodiment, sliders 206 are provided at the ends of the two movable shafts 203, and guide grooves 2010 are provided on the inner sides of the side panels 201 in the moving direction of the movable shafts 203. The sliders 206 at both ends of the movable shaft 203 are respectively engaged in the corresponding guide grooves 2010 on the two side panels 201, and a pressing spring 207 is provided in the guide groove 2010 to provide a return elastic force to the slider 206. Such a structural arrangement ensures that, under the elastic force of the pressing spring 207, the two movable shafts 203 always have a thrust away from the connection position of the delivery hose 205 and the main pipe 21. This thrust can keep the delivery hose 205 in a tensioned state regardless of whether the main pipe 21 rotates forward or reverse, thereby ensuring stable medium transportation.

[0028] Specifically, such as Figure 5-Figure 7 As shown, in order to increase the tensioned controllable length of the delivery hose 205 within a limited space, in this embodiment, the moving paths of the two movable shafts 203 at the corresponding positions of each delivery hose 205 are in a V-shaped structure, so that when the two movable shafts 203 move toward the front end of the path, the two movable shafts 203 move away from each other. At this time, the length of the delivery hose 205 pulled on the two movable shafts 203 increases.

[0029] Example 2 like Figure 3 、 Figure 5 and Figure 6 As shown, this embodiment provides a technical solution: a foaming device for XPS extruded board. In order to achieve the control and driving effect of the support control mechanism 3 on the cleaning and coating integrated mechanism 2, on the basis of Example 1, a lower mold base 13 is provided at the bottom of the lower mold body 11, and an upper mold base 12 is provided at the top of the upper mold body 10. The four corners of the lower mold base 13 and the upper mold base 12 are movably connected by columns 14; The support and control mechanism 3 is arranged above the lower mold base 13, and the support and control mechanism 3 includes a bracket 30 and a slide 303, wherein there are two brackets 30 in a total of a U-shaped structure, which are respectively installed above the lower mold base 13 at both ends of the lower mold body 11 and parallel to the width direction of the lower mold body 11. There are two slides 303 in a total of ...

[0030] Specifically, such as Figure 3 、 Figure 5 and Figure 6 As shown, in order to realize the movement control of the slide 303, in this embodiment, a track groove 300 is opened on the upper edge of the bracket 30 along the length direction, and a screw rod 301 is rotatably installed inside the track groove 300 along the length direction. A first motor 304 is fixedly installed at one end of the bracket 30, and the output shaft of the first motor 304 is connected to one end of the screw rod 301; A slider 302 is installed at the bottom of the slide 303, and a screw nut adapted to the screw rod 301 is nested inside the slider 302. The slider 302 is slidably assembled in the track groove 300, and the screw rod 301 inside the track groove 300 is sleeved with the screw nut inside the slider 302, so that when the first motor 304 is running, it drives the screw rod 301 to rotate, thereby driving the slide 303 to slide along the length direction of the bracket 30 with the cooperation of the screw nut.

[0031] Example 3 Specifically, such as Figure 10 As shown, in order to provide a temperature inside the upper mold body 10 and the lower mold body 11 to meet the foaming needs of the extruded board, in this embodiment, a heating plate 111 is provided inside the upper mold body 10 and the lower mold body 11, and the heating plate 111 adopts an annular structure to surround the upper mold body 10 and the lower mold body 11.

[0032] Specifically, such as Figure 11 As shown, in order to quickly cool down the extruded board after foaming and molding, and improve the demolding efficiency, in this embodiment, a cooling channel 110 is further provided inside the upper mold body 10 and the lower mold body 11. The cooling channel 110 has a multi-section continuous bending structure, which is flattened on the upper wall of the upper mold body 10 and the lower wall of the lower mold body 11 to form a cooling structure. When in use, the cooling liquid is passed into the cooling channel 110 to achieve rapid cooling of the upper mold body 10 and the lower mold body 11.
