[0039] Reference below Figures 1 to 3 A composite resin tile, a production device, a control method and a production method according to an embodiment of the present invention are described.

[0040] The composite resin tile of the first embodiment of the present invention, referring to Figure 2 , including a transversely extending metal plate 710, resin layers 720 are stacked on the upper and lower sides of the metal plate 710, the front side of each resin layer 720 is provided with a front edge protruding from the metal plate 710, the rear side of each resin layer 720 is provided with a rear edge protruding from the metal plate 710, the front edges of the two resin layers 720 are connected, and the rear edges of the two resin layers 720 are connected.

[0041] By setting the metal plate 710, even if the resin layer 720 is aged to a certain extent after long-term use, the strength of the composite resin tile is still relatively large, thereby avoiding the problem of the composite resin tile being broken through when encountering hail weather; the two resin layers 720 are respectively called the first layer and the second layer, and the first layer is arranged above the second layer, and the front edge of the first layer is adhered to and fixedly connected with the front edge of the second layer, and the rear edge of the first layer is adhered to and fixedly connected with the rear edge of the second layer, so as to make the structure more stable and avoid the problem of separation of the resin layer 720 and the metal plate 710; the left edge and the right edge of the resin layer 720 are both flush with the metal plate 710, so that when producing the composite resin tile, it can be produced continuously in the horizontal direction and then cut to a suitable length, which is convenient for production.

[0042] In some embodiments of the present invention, the two resin layers 720 are integrally formed components, so that the connection between the first layer and the second layer is more secure and the structure is more stable.

[0043] In some embodiments of the present invention, the metal plate 710 is an aluminum alloy material component. Aluminum alloy meets the material strength requirements and has a low density. It is a lightweight material that is easy to transport and install and is suitable for making composite resin tiles. Of course, the metal plate 710 can also be made of stainless steel or other suitable materials.

[0044] The production device of the second embodiment of the present invention is used to produce the above-mentioned composite resin tile, referring to Figure 1 , the production equipment includes:

[0045] The composite mold 300 has a composite channel disposed therein, which runs through the composite mold 300 in the transverse direction, and a pouring channel disposed on the side wall of the composite channel; one end of the pouring channel is connected to the composite channel, and the other end of the pouring channel extends to the outer surface of the composite mold 300, and liquid resin can be poured into the composite channel through the pouring channel when in use. The composite mold 300 is a metal material component, and an electric heating rod or other heating component is disposed in the composite mold 300, so that the resin in the composite channel can remain in a liquid or molten state, so as to facilitate adhesion to the surface of the metal plate 710.

[0046] The conveying mechanism includes a feeding module 600 arranged on the right side of the composite channel and a traction module 100 arranged on the left side of the composite channel. A plate channel is arranged between the traction module 100 and the feeding module 600. The plate channel runs through the composite flow channel. A gap is arranged between the inner wall of the composite flow channel and the plate channel. The front-to-back dimensions and vertical dimensions of the composite flow channel are larger than those of the plate channel. The metal plate 710 can be a plate with a smaller thickness, so that the metal plate 710 can be stored in the form of a coil; the feeding module 600 is used to feed the metal plate 710 to the left, and the feeding module 600 includes a reel, and the metal plate 710 can be continuously fed from the reel and conveyed to the left along the plate channel; the traction module 100 is used to pull the formed composite resin tile to the left, and the traction module 100 includes at least one roller group, and the roller group includes an upper roller and a lower roller. The axial directions of the upper roller and the lower roller are both front-to-back directions, and one of the upper roller and the lower roller is an active roller and is driven by a motor. The left end of the plate channel is arranged between the upper roller and the lower roller, so that the formed composite resin tile is clamped between the upper roller and the lower roller, and the rotation of the active roller can realize the traction of the formed composite resin tile to the left.

[0047] When in use, the conveying mechanism is used to drive the metal plate 710 to be conveyed to the left along the plate channel, and at the same time, resin is poured into the composite channel through the pouring channel, so that the resin can be attached to the surface of the metal plate 710, thereby achieving the purpose of producing the composite resin tile 700.

[0048] In some embodiments of the present invention, reference Figure 3The composite flow channel includes a composite section 320 and a molding section 310. The composite section 320 is arranged on the right side of the molding section 310. The radial dimension of the gap along the composite flow channel is called the thickness dimension. The thickness dimension of the gap in the molding section 310 is smaller than the thickness dimension of the gap in the composite section 320. The infusion channel is connected to the composite section 320. The cross-sectional shape of the molding section 310 is consistent with the cross-sectional shape of the composite resin tile. The molding section 310 is used to block excess resin so that the thickness of the resin layer 720 meets the preset thickness. By setting the traction module 100, the metal plate 710 has a certain tension during the composite process to prevent the metal plate 710 from touching the inner wall of the molding section 310, resulting in one of the resin layers 720 being too thick and the other resin layer 720 being too thin. By setting the composite section 320, the distance between the inner wall of the composite section 320 and the plate channel is large, and the resin is The flow resistance in section 320 is small, and the resin can flow evenly to the upper and lower sides of the plate channel; an opening for the metal plate 710 to enter the composite section 320 is provided at the right end of the composite section 320, and the plate channel passes through the opening. A sealing component 330 is provided between the plate channel and the side wall of the opening to prevent the resin from leaking from the right end of the composite mold 300. The sealing component 330 includes an upper piece and a lower piece, and the plate channel is provided between the upper piece and the lower piece. The upper piece and the lower piece are both elastic components, and the upper piece and the lower piece can be rubber material components.

[0049] In some embodiments of the present invention, the production device further includes a cooling mechanism 200 and a profiling mechanism 500. The profiling mechanism 500 is disposed between the feeding module 600 and the composite mold 300, and the cooling mechanism 200 is disposed between the traction module 100 and the composite mold 300. The profiling mechanism 500 includes a roller machine, which is a commonly used device in this field and can be directly purchased from the market. Its specific structure is not described in detail here. The profiling mechanism 500 is used to perform profiling treatment on the metal plate 710 to process the metal plate 710 into a corrugated shape. The cross-section of the forming section 310 of the composite flow channel is also corrugated, which is compatible with the metal plate 710 processed into a corrugated shape, so that the manufactured composite resin tile is also corrugated, which improves the structural strength and meets the use requirements.

[0050] The cooling mechanism 200 includes at least two fans 210, which are respectively arranged on the upper and lower sides of the plate channel. The air supply directions of the two fans 210 are both toward the plate channel, so that the composite resin tiles sent out from the composite mold 300 can be quickly cooled, the hardness of the two resin layers 720 can be increased, and dents can be prevented from being generated when the resin layers 720 come into contact with the traction device.

[0051] In some embodiments of the present invention, there are two infusion channels, which are respectively arranged above and below the plate channel. When used in this way, part of the resin material can be injected into the composite flow channel from above the plate channel, and part of the resin material can be injected into the composite flow channel from below the plate channel, which is conducive to making the resin flow evenly to the upper and lower sides of the metal plate 710.

[0052] In some embodiments of the present invention, the production device further includes a perfusion system, which includes a perfusion main pipe 400, the end of which is connected to two perfusion branch pipes 420, the two perfusion branch pipes 420 are connected to two perfusion channels one by one, and the perfusion main pipe 400 is provided with a metering pump 410. When in use, the resin is injected from the perfusion main pipe 400 through the two perfusion branch pipes 420 to the upper side and the lower side of the composite flow channel respectively. By providing the metering pump 410, it is helpful to accurately control the amount of resin added to the composite flow channel, and adapt to the speed of the conveying mechanism conveying the metal plate 710, so that the resin will not overflow due to excessive amount, and will not cause vacancies in the resin layer 720 due to insufficient amount.

[0053] In some embodiments of the present invention, the production device further includes a controller, two pressure sensors 440 are provided in the composite section 320, and the two pressure sensors 440 are respectively provided above and below the plate passage, one of the infusion branches 420 is provided with a proportional valve 430, and the proportional valve 430 and the two pressure sensors 440 are both electrically connected to the controller, and the controller is configured to control the opening of the proportional valve 430 according to the pressure signals obtained from the two pressure sensors 440. The two infusion branches 420 are respectively referred to as an upper branch and a lower branch, and the two pressure sensors 440 are respectively referred to as an upper sensor and a lower sensor, and the upper branch and the upper sensor are both provided above the plate passage, so that the upper branch can inject resin to the upper side of the plate passage, and the upper sensor can detect the pressure on the upper side of the plate passage, which is referred to as the upper side pressure; the lower branch and the lower sensor are both provided below the plate passage, so that the lower branch can inject resin to the lower side of the plate passage, and the lower sensor can detect the pressure on the lower side of the plate passage, which is referred to as the lower side pressure.

[0054] The proportional valve 430 is set on the upper branch pipe or the lower branch pipe. Taking the lower branch pipe as an example, a pressure difference range is set before production. During production, when the difference between the lower pressure and the upper pressure is greater than the maximum value of the pressure difference range, the opening of the proportional valve 430 is controlled to decrease, so that the lower pressure decreases and the upper pressure increases; when the difference between the lower pressure and the upper pressure is less than the minimum value of the pressure difference range, the opening of the proportional valve 430 is controlled to increase, so that the lower pressure increases and the upper pressure decreases, until the difference between the lower pressure and the upper pressure is within the pressure difference range. In this way, the vertical force on the metal plate 710 tends to be balanced, the metal plate 710 will not deviate up and down, and the thickness of the resin layer 720 of the manufactured composite resin tile is accurate.

[0055] The control method of the third embodiment of the present invention is applied to the above-mentioned production device, and the control method comprises the following steps:

[0056] Step S310, setting the feeding speed of the feeding module 600;

[0057] Step S320, determining the output flow rate of the metering pump 410 according to the feeding speed;

[0058] Step S330, obtaining pressure signals from two pressure sensors 440;

[0059] Step S340, controlling the opening of the proportional valve 430 according to the two pressure signals so that the pressure difference between the upper and lower parts of the plate passage is within a preset range.

[0060] When the opening of the proportional valve 430 is adjusted to control the pressure difference between the upper and lower parts of the plate passage, the total amount of resin injected into the composite mold 300 by the two injection pipes 420 will not change, thereby avoiding excessive or insufficient resin.

[0061] The production method of the fourth embodiment of the present invention uses the above-mentioned production device to produce composite resin tiles, and the production method comprises the following steps:

[0062] Step S100, using the feeding module 600 to feed out the metal plate 710;

[0063] Step S200, using the pressing mechanism 500 to process the metal plate 710 into a corrugated shape;

[0064] Step S300, using the composite mold 300 to composite the resin onto the surface of the metal plate 710 to form a composite resin tile;

[0065] Step S400, using the cooling mechanism 200 to cool the composite resin tile;

[0066] Step S500 , using the pulling module 100 to pull the composite resin tile in a direction away from the composite mold 300 .

[0067] It is understandable that if the metal plate 710 is first compounded with the resin material and then subjected to the press process, the metal plate 710 and the resin layer 720 may separate during the press process, resulting in an uncompact structure. In the present embodiment, when producing composite resin tiles, the metal plate 710 is fed out of the feeding module 600 and processed into a corrugated shape by the press mechanism 500, and then compounded with the resin material; the corrugated composite resin tiles can be continuously produced in the horizontal direction and then cut to a suitable length, and the production efficiency is high.
