[0051] It should also be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0052] See also Figure 1 , which is a schematic diagram of a feeding device provided in an embodiment of the present application. Figure 2 , which is a schematic diagram of a spraying device provided in an embodiment of the present application.

[0053] like Figure 1 and Figure 2 As shown, the loading spraying device provided in the embodiment of the present application includes: a feeding device and a spraying device. The feeding device includes a material placement shaft 101, a tensioning wheel assembly 102, a material placement plate 103 and a conveying mechanism assembly 104, and the spraying device includes a spray gun slide rail 201 and a spray gun 202.

[0054] The material placement shaft 101 is used to place rolled materials. The first end of the material is connected to the material placement shaft 101. The second end of the material is laid on the material placement plate 103 through the tensioning wheel set 102. The tensioning wheel set 102 is used to tension the material so that the material is flat on the material placement plate 103. The transport mechanism assembly 104 is arranged at one end of the material placement plate 103 away from the tensioning wheel set 102. The transport mechanism assembly 104 is used to move the unsprayed material to the material placement plate 103. The spray gun slide rail 201 is connected to the spray gun 202. The spray gun 202 is used to move through the spray gun slide rail 201 to spray the target area of ​​the material on the material placement plate 103.

[0055] It should be noted that the material in the embodiment of the present application can be a non-woven fabric or other materials that can be rolled. The spraying raw material sprayed by the spray gun in the embodiment of the present application can be latex or other spraying raw materials that can be sprayed, which is not limited in the embodiment of the present application. The material placement shaft in the embodiment of the present application can be an inflatable shaft, which is not limited in the embodiment of the present application.

[0056] The transport mechanism assembly in the embodiment of the present application can move the material placed on the material placement plate away from one end of the tensioning wheel group, so that the unsprayed material can be moved to the material placement plate through the tensioning wheel group, thereby realizing automatic feeding and leveling of the material. Specifically, the transport mechanism assembly in the embodiment of the present application can include a transport clamp, which can clamp the material and move the material in a direction away from the tensioning wheel group, so that the unsprayed material can be moved to the material placement plate. After the unsprayed material is placed on the material placement plate, the spray gun in the present application can be moved by the spray gun slide rail, and the spray gun can spray the unsprayed material on the material placement plate while moving, so that the target area on the material is sprayed and a sprayed product is obtained.

[0057] The loading spraying device provided in the embodiment of the present application can automatically lay the rolled material on the material placement shaft on the material placement plate through the feeding device, and automatically spray the target area of ​​the material by moving the spray gun through the spray gun slide rail in the spraying device. In this way, the loading spraying device provided in the present application can automatically spray the material to obtain a sprayed product on the one hand, and on the other hand, the loading spraying device provided in the present application has a high accuracy in placement and spraying, which can improve the consistency between the multiple sprayed products obtained and the quality of the sprayed products.

[0058] As a possible implementation, Figure 3 As shown, the tension wheel set 102 in the embodiment of the present application includes: a first tension wheel 112, a second tension wheel 122, a third tension wheel 132 and a fourth tension wheel 142. The second end of the material passes through the first tension wheel 112, the second tension wheel 122, the third tension wheel 132 and the fourth tension wheel 142 in sequence and is laid on the material placement plate 103. As an example, in the embodiment of the present application, the height of the second tension wheel 122 and the height of the material placement shaft 101 are not lower than the height of the first tension wheel 112, and the height of the second tension wheel 122 and the height of the fourth tension wheel 142 are not lower than the height of the third tension wheel 132. It should be noted that the height difference between the material placement shaft 101, the first tension wheel 112, the second tension wheel 122, the third tension wheel 132 and the fourth tension wheel 142 in the embodiment of the present application is to tension the material passing through the tension wheel set. In actual applications, the height of the tensioning wheel group in the embodiment of the present application can also be kept consistent, or arranged according to other height rules. The embodiment of the present application does not limit the relative heights between the first tensioning wheel 112, the second tensioning wheel 122, the third tensioning wheel 132 and the fourth tensioning wheel 142. As long as the purpose of tensioning the material can be achieved, it should be within the scope outlined by the technical solution of the present application.

[0059] In an embodiment of the present application, the conveying mechanism assembly can move the material on the material placement plate a first preset distance away from the fourth tensioning wheel after the spray gun completes one spraying operation, so that the spray gun can spray the unsprayed material again, thereby realizing the automation of the entire feeding and spraying process.

[0060] The third tensioning wheel can be connected to the tensioning wheel servo motor; the tensioning wheel servo motor is used to move the third tensioning wheel upward or in other directions by a second preset distance when the conveying mechanism assembly moves the material on the material placement plate, thereby reducing the length of the material between the second tensioning wheel and the fourth tensioning wheel, that is, partially moving the unsprayed material originally between the second tensioning wheel and the fourth tensioning wheel to the material placement plate.

[0061] As an example, Figure 3 As shown, the tension wheel servo motor can move the third tension wheel 132 upward, so that the material length between the second tension wheel 122 and the fourth tension wheel 142 is reduced. It should be noted that in the embodiment of the present application, the third tension wheel is continuously moved upward to approach the fourth tension wheel. When the height of the third tension wheel is higher than or equal to the first height, the third tension wheel cannot continue to reduce the material length between the second tension wheel 122 and the fourth tension wheel 142 by moving it upward, or the reduction in the length of the material between the second tension wheel 122 and the fourth tension wheel 142 is very small. At this time, the third tension wheel can be moved back to the lowest point. As a possible implementation, a positioning sensor (not shown in the figure) can be provided on the third tension wheel 132. The positioning sensor is used to detect the height of the third tension wheel 132 to detect the size relationship between the height of the third tension wheel 132 and the first height.

[0062] In the embodiment of the present application, the tensioner servo motor is also used to control the third tensioner to descend a third preset distance after the height of the third tensioner is higher than or equal to the first height, so that the third tensioner moves back to the lowest point. Figure 3 As shown, the material placement shaft 101 is connected to the feeding motor 105; the feeding motor 105 is used to control the rotation of the material placement shaft 101 when the third tensioning wheel 132 descends, so that the material on the material placement shaft 101 moves toward the first tensioning wheel 112. While the third tensioning wheel 132 descends, the material placement shaft 101 in the embodiment of the present application begins to discharge the material, increasing the length of the material between the second tensioning wheel 122 and the fourth tensioning wheel 142, so that the third tensioning wheel 132 moves upward again, so that the unsprayed material between the second tensioning wheel 122 and the fourth tensioning wheel 142 is partially moved to the material placement plate 103. It can be seen that in the embodiment of the present application, through the cooperation between the third tensioning wheel and the material placement shaft, the flatness of the material on the material placement plate can be better guaranteed while realizing automatic feeding, so that the subsequent spraying is more uniform and the quality of the obtained sprayed product is better.

[0063] In the embodiments of the present application, Figure 3 The feeding device shown also includes a clamping plate 106; the clamping plate 106 is arranged at both ends of the material placement plate 103; the clamping plate 106 is used to fix the material on the material placement plate 103 when the spray gun is spraying; the clamping plate 106 is also used to loosen the material on the material placement plate 103 when the material on the material placement plate 103 moves, so that the unsprayed material can move to the material placement plate 103.

[0064] As a possible implementation, the feeding device may further include a non-return eccentric wheel 107. The non-return eccentric wheel 107 is disposed on one end of the material placement plate 103 close to the fourth tensioning wheel 142. The non-return eccentric wheel 107 is used to prevent the material on the material placement plate 103 from moving toward the fourth tensioning wheel 142. It should be noted that the non-return eccentric wheel 107 can prevent the material from moving back after the conveying mechanism assembly 104 moves the material, thereby making the target area of ​​the subsequent spraying inaccurate.

[0065] like Figure 3 As shown, the feeding device provided in the embodiment of the present application may also include a material presence sensor 108, which can detect whether the material has been sprayed. When the material has been sprayed, new material needs to be placed on the material placement shaft 101 for subsequent spraying. The material placement shaft 101 in the embodiment of the present application may also be connected to a material position adjustment mechanism 109 to adjust materials in different positions or different sizes in the future.

[0066] The above introduces the loading device provided in the embodiment of the present application. The following introduces the spraying device provided in the embodiment of the present application.

[0067] like Figure 4 As shown, the spraying device also includes a protective cover 203, a waste liquid tank 204 and an exhaust filter 205. The protective cover 203 is arranged on the material placement plate 103, and the spray gun 202 is arranged inside the protective cover 203. The waste liquid tank 204 is arranged below the material placement plate 103, and the dust cover 203 is also provided with a through hole connected to the exhaust filter 205. It should be noted that the protective cover 203 can prevent the spraying raw materials sprayed from the spray gun 202 from diffusing. The exhaust filter 205 is arranged on the protective cover 203 to filter the gas containing the spraying raw materials in the protective cover 203. The waste liquid tank 204 can collect the excess spraying raw materials after spraying. The spray gun slide rail 201 in the present application can also be provided with a spray gun adjustment mechanism 207, and the spray gun adjustment mechanism 207 can adjust the angle or height of the spray gun 202 to achieve a better spraying effect.

[0068] like Figure 5As shown, the spray gun slide rail 201 in the embodiment of the present application can be a linear slide rail, and the spray gun 202 is connected to the spray gun servo motor 206. The spray gun servo motor 206 drives the spray gun 202 to move linearly on the linear slide rail so as to spray the material linearly.

[0069] The spraying device provided in the embodiment of the present application may also include a syringe pump 208, an agitator 209 and a digital pressure gauge 210. The agitator 209 is used to stir the spraying raw material; the syringe pump 208 is used to input the spraying raw material into the spray gun 202 at a preset flow rate. It should be noted that the agitator 209 in the present application may be a magnetic agitator. As an example, the spraying raw material in the present application may specifically include C-line latex and T-line latex. The C-line latex and T-line latex are stored in different containers, respectively, and the agitator 209 stirs them respectively, and then injects them into two different spray guns 202 through two different syringe pumps 208 for spraying.

[0070] In summary, the loading spraying device provided in the embodiment of the present application can automatically lay the rolled material on the material placement shaft on the material placement plate through the feeding device, and automatically spray the target area of ​​the material by moving the spray gun through the spray gun slide rail in the spraying device. In this way, the loading spraying device provided in the present application can, on the one hand, automatically spray the material to obtain a sprayed product, and on the other hand, the loading spraying device provided in the present application has a high accuracy in placement and spraying, which can improve the uniformity between the obtained sprayed products and the quality of the sprayed products.
