Description

Technical Field

[0001] The invention belongs to the technical field of paper tray production inspection, and specifically relates to a quality inspection device for paper tray production and a use method thereof. Background Art

[0002] A paper tray is a paper product used to support items. The advantages of a paper tray include low cost, environmental protection, recyclability, and light weight. Its production process and shape can be designed and customized according to different needs. During the production process, the finished product needs to be tested for strength to determine the pressure limit that the paper tray can withstand when it is reused, so as to ensure the reliability of the paper tray.

[0003] Most of the existing paper support strength testing devices have simple structures and are single-point tests. When increasing pressure to push the paper support downward, the pressure is easily too concentrated, which makes it easier to cause the paper support to bend or break. When the paper support is in use, the supported objects are often spread all over the paper support, so the same weight pressure will not cause the paper support to bend or break, which will lead to inaccurate detection.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0010] The positioning spraying mechanism is installed in the operating support platform, and is used to support the paper support, so as to facilitate the positioning and calibration of the paper support, and has the function of flaw detection and marking of the paper support;

[0011] Among them, the positioning spraying mechanism includes a supporting pile, on which a flaw detector and multiple intelligent control valves are installed, multiple nozzles are fixedly connected to the intelligent control valve, and a storage tank is also threadedly connected below the intelligent control valve. The flaw detector includes a monitoring module, a positioning module and a control module.

[0013] In one or more embodiments of the present invention, a plurality of sliding grooves are formed on the operating support platform to provide space for the sliding of the sliding support block, so that the sliding positioning block has space to move, and the circular paper holder can be pushed to the bottom of the lower pressure column block. A driving motor is installed on the side wall of the sliding groove to drive the rotation of the driving screw to provide power for positioning the paper holder. The driving motor is fixedly connected with a driving screw to drive the movement of the sliding support block to play a role in transmitting power.

[0014] A sliding support block is threadedly connected to the driving screw, and the sliding support block is fixedly connected to the sliding positioning block. The driving screw is used to drive the sliding support block to move, thereby achieving the effect of driving the sliding positioning block, and also has the function of supporting the sliding positioning block to prevent the sliding positioning block from falling off.

[0015] In one or more embodiments of the present invention, a first fixed bearing is fixedly connected between the end of the driving screw away from the driving motor and the operating support platform, which is used to fix the driving screw to prevent the driving screw from shaking or tilting, thereby improving the stability of the device and not affecting the rotation of the driving screw, thereby facilitating the sliding of the sliding support block. A second fixed bearing is fixedly connected between the downward pressure control screw and the downward pressure splint, which is used to support the downward pressure splint to prevent the downward pressure splint from falling off and ensure that the rotation of the downward pressure control screw will not drive the rotation of the downward pressure splint.

[0016] In one or more embodiments of the present invention, a first contraction cavity is excavated in the sliding positioning block to provide space for the sliding of the first limit support block, so that the fixed column has a certain movement space, and a first limit support block is slidably arranged in the first contraction cavity to support the fixed column and squeeze the first push spring;

[0017] The first limit support block is fixedly connected with a fixing column, which is used to support the fixing column so that the fixing column will not fall off, and has the function of pushing the fixing column to move outward, thereby playing an auxiliary role in clamping the circular paper holder, and the other end of the fixing column is fixed with a push plate;

[0018] A first pushing spring is fixedly connected between a side of the first limit support block away from the fixed column and the sliding positioning block, and is used to push the first limit support block, so that the fixed column always has a force to push the push plate outward, and only when the circular paper holder is positioned directly below the downward pressure column block, can multiple push plates contact the trigger sheet at the same time.

[0019] In one or more embodiments of the present invention, a storage groove matching the push plate is further bored on the sliding positioning block to facilitate the insertion of the push plate and realize the contact between the push plate and the trigger plate. A trigger plate is installed on the side wall of the storage groove. Only when multiple push plates are in contact with the trigger plate, it indicates that the circular paper support is fixed in place and is directly below the downward pressure column block, and then it can be pressurized for detection.

[0020] In one or more embodiments of the present invention, a groove is chiseled on the lower pressure column block to facilitate the setting of the tensioning spring, thereby pulling the uniform force rotating plate. A tensioning spring is fixedly connected between the uniform force rotating plate and the lower pressure column block to pull the uniform force rotating plate and prevent the uniform force rotating plate from shaking.

[0021] In one or more embodiments of the present invention, a second shrinkage cavity is excavated in the uniform force rotating plate to provide space for the sliding of the second limit support block, a second limit support block is slidably arranged in the second shrinkage cavity to support the limit clamping block to prevent the limit clamping block from falling off, and a limit clamping block is fixed on the second limit support block to clamp the clamping ring, so that the clamping ring is not easy to move, and then the clamping ring is used to clamp multiple uniform force rotating plates to prevent them from shaking;

[0022] A plurality of second pushing springs are fixedly connected between a side of the second limit support block away from the limit clamping block and the uniform force rotating plate, which are used to push the second limit support block, so that the second limit support block drives the limit clamping block to extend outward, and then the limit clamping block is used to clamp the clamping ring to achieve the function of fixing the plurality of uniform force rotating plates. The plurality of limit clamping blocks are buckled with clamping rings to fix the plurality of uniform force rotating plates, so that the plurality of uniform force rotating plates cannot be stretched out, thereby reducing the force area of ​​the circular paper holder and realizing the detection of multiple states.

[0023] In one or more embodiments of the present invention, a plurality of protrusions are fixed on the storage tank to facilitate the staff to rotate the storage tank, thereby facilitating the disassembly and installation of the storage tank. A supporting electric push rod is installed below the supporting pile to control the lifting and lowering movement of the lifting column rod, thereby facilitating the control of the lifting and lowering movement of the supporting pile.

[0024] A lifting column rod is fixedly connected between the supporting electric push rod and the supporting pile, and is used to support the lifting column rod and drive the lifting column rod to move up and down.

[0025] A method for using a quality inspection device for paper tray production, comprising the following steps:

[0026] S1. The staff places the produced circular paper holder on the support pile, and then starts multiple driving motors at the same time, and drives the movement of the sliding support block by rotating the driving screw, thereby driving multiple sliding positioning blocks to move together, so that the multiple sliding positioning blocks push the circular paper holder to move toward the central axis position of the operating support platform, and finally the multiple sliding positioning blocks will push the circular paper holder to be located directly below the lower pressure column block;

[0027] S2. Moreover, the circular paper holder can be scooped up by the push shovel and moved onto the push shovel. During the fixing process, the circular paper holder can push the fixing column to retract into the storage slot. When all the fixing columns are in contact with the trigger sheet, the positioning of the circular paper holder is completed. Then the staff rotates the downward control screw to drive the downward clamping plate to descend, thereby clamping and fixing the circular paper holder.

[0028] S3, then, start the supporting electric push rod, so that the supporting electric push rod controls the lifting column rod to descend, so that there is no support under the circular paper support, and then start the pressurizing cylinder to control the pressing column block to gradually descend through the pressurizing cylinder, so that the pressing column block drives multiple uniform force rotating plates to press on the circular paper support, so as to achieve the purpose of checking the quality of the paper support;

[0029] S4. The lower end of the uniform force rotating plate will drive the stretching roller to slide on the circular paper holder, so that the multiple uniform force rotating plates can be stretched out, thereby increasing the contact area of ​​the force applied to the circular paper holder and improving the detection effect. When the uniform force rotating plate is blocked by the limit block and cannot continue to rotate, the lowest point of the stretching roller will be flush with the lowest point of the lower pressure column block, thereby ensuring the uniformity of the pressure applied to the circular paper holder;

[0030] S5. During the process of the pressure applied by the pressing column block to the circular paper support, the flaw detector will continue to detect the bottom of the circular paper support. When the applied pressure increases to a certain extent, the circular paper support will be deformed, and the flaw detector can detect it immediately.

[0031] S6. When the flaw detector detects that the round paper tray is deformed or bulged, it can quickly organize the data and determine the location of the bulge through the positioning module. Then, the control module starts the intelligent control valve in the corresponding area, so that multiple nozzles can spray paint outward, thereby achieving a marking effect and facilitating subsequent observation by staff.

[0032] Compared with the prior art, the present invention improves the stability of paper support detection by setting up corresponding mechanisms, and disperses the pressure on the paper support, thereby making the paper support evenly subjected to pressure, thereby improving the accuracy of paper support detection.

[0044] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0045] like Figure 1-Figure 8 As shown, a quality inspection device for paper tray production in one embodiment of the present invention includes: a supporting pad 1, a positioning and fixing mechanism 2, a pressurizing inspection mechanism 3 and a positioning spraying mechanism 4.

[0046] like Figure 1-Figure 5As shown, the positioning and fixing mechanism 2 is installed on the support pad 1, and the positioning and fixing mechanism 2 includes an operating support platform 201, which is used to support the paper holder and provide conditions for fixing the paper holder. A plurality of evenly distributed sliding positioning blocks 202 are slidably arranged on the operating support platform 201, which are used to push the circular paper holder to the bottom of the pressing column block 303, so as to facilitate pressurization detection. A push shovel 203 is fixedly connected to one side of the plurality of sliding positioning blocks 202, and the cross section of the push shovel 203 is a right-angled trapezoid, which is convenient for shoveling the push shovel 203, so as to make the bottom of the circular paper holder suspended in the air, so as to facilitate pressurization detection.

[0047] like Figure 1-Figure 2 As shown, a downward pressing clamp 204 is provided on one side of the sliding positioning block 202, and a downward pressing control screw 205 is rotatably connected to the downward pressing clamp 204. The downward pressing control screw 205 is threadedly connected to the sliding positioning block 202. By rotating the downward pressing control screw 205, the downward pressing control screw 205 drives the downward pressing clamp 204 to move downward, and then the circular paper holder is pressed by the downward pressing clamp 204 to fix the circular paper holder.

[0048] Among them, a plurality of support column legs 206 are fixedly connected between the bottom of the operation support platform 201 and the support pad 1, which are used to support the operation support platform 201, ensure the stability of the operation support platform 201, and prevent the operation support platform 201 from being skewed, thereby ensuring the level of the circular paper tray and preventing uneven force during pressurization detection, thereby affecting the accuracy of pressurization detection.

[0049] like Figure 1-Figure 2 As shown, a plurality of sliding grooves 207 are formed on the operating support platform 201 to provide space for the sliding of the sliding support block 211, so that the sliding positioning block 202 has space to move, and the circular paper holder can be pushed to the right below the pressing column block 303. A driving motor 208 is installed on the side wall of the sliding groove 207 to drive the rotation of the driving screw 209 to provide power for positioning the paper holder. The driving motor 208 is fixedly connected with the driving screw 209 to drive the movement of the sliding support block 211 to play the role of transmitting power.

[0050] like Figure 1-Figure 2 As shown, a sliding support block 211 is threadedly connected to the driving screw 209, and the sliding support block 211 is fixedly connected to the sliding positioning block 202. The driving screw 209 drives the sliding support block 211 to move, thereby achieving the effect of driving the sliding positioning block 202, and also has the function of supporting the sliding positioning block 202 to prevent the sliding positioning block 202 from falling off.

[0051] like Figure 1-Figure 2As shown, a first fixed bearing 210 is fixedly connected between the end of the driving screw 209 away from the driving motor 208 and the operating support platform 201, which is used to fix the driving screw 209 to prevent the driving screw 209 from shaking or tilting, improve the stability of the device, and will not affect the rotation of the driving screw 209, thereby facilitating the sliding of the sliding support block 211. A second fixed bearing 212 is fixedly connected between the pressing control screw 205 and the pressing clamping plate 204, which is used to support the pressing clamping plate 204 to prevent the pressing clamping plate 204 from falling off, and ensure that the rotation of the pressing control screw 205 will not drive the rotation of the pressing clamping plate 204.

[0052] like Figure 1-Figure 2 As shown, a first contraction cavity 213 is excavated in the sliding positioning block 202 to provide space for the sliding of the first limit support block 214, so that the fixed column 215 has a certain moving space. The first limit support block 214 is slidably arranged in the first contraction cavity 213 to support the fixed column 215 and squeeze the first push spring 217.

[0053] Specifically, a fixing column 215 is fixedly connected to the first limiting support block 214, which is used to support the fixing column 215 so that the fixing column 215 will not fall off, and has the function of pushing the fixing column 215 to move outward, thereby assisting in clamping the circular paper holder. A push plate 216 is fixed to the other end of the fixing column 215.

[0054] In addition, a first pushing spring 217 is fixedly connected between the side of the first limit support block 214 away from the fixed column 215 and the sliding positioning block 202, which is used to push the first limit support block 214, so that the fixed column 215 always has the force to push the push plate 216 outward, and only when the circular paper holder is positioned directly below the downward pressure column block 303, can multiple push plates 216 contact the trigger plate 218 at the same time.

[0055] like Figure 1-Figure 2 As shown, a storage groove matching the push plate 216 is also excavated on the sliding positioning block 202 to facilitate the insertion of the push plate 216 and realize the contact between the push plate 216 and the trigger plate 218. A trigger plate 218 is installed on the side wall of the storage groove. Only when multiple push plates 216 are in contact with the trigger plate 218, it indicates that the circular paper holder is fixed in place and is directly below the downward pressure column block 303, and then it can be pressurized for detection.

[0056] like Figure 1-Figure 6As shown, the pressure detection mechanism 3 is installed on one side of the operating support platform 201. The pressure detection mechanism 3 includes a support frame 301, which provides support force for the pressure cylinder 302 to prevent the pressure cylinder 302 from shaking or falling off. The pressure cylinder 302 is installed on the support frame 301, which is used to drive the lifting and lowering movement of the pressure column block 303. The pressure cylinder 302 is fixedly connected with the pressure column block 303 below, which is used to push the paper support downward, so that the paper support is subjected to pressure to achieve the effect of pressure detection. A plurality of uniform force rotating plates 304 are rotatably connected to the pressure column block 303, which are used to assist in squeezing and pushing the circular paper support downward, thereby achieving the effect of pressure detection.

[0057] like Figure 1-Figure 8 As shown, a fixed shaft rod 312 is fixed on the other end of the uniform force rotating plate 304, and a stretching roller 313 is rotatably connected to the fixed shaft rod 312, so that multiple uniform force rotating plates 304 can be stretched out to increase the pressurized contact area. Multiple limit blocks 305 are fixed on the lower pressure column block 303 to limit the uniform force rotating plate 304 and prevent the uniform force rotating plate 304 from rotating excessively. When the uniform force rotating plate 304 is blocked by the limit blocks 305 and cannot continue to rotate, the lowest point of the stretching roller 313 is at the same horizontal position as the lowest point of the lower pressure column block 303, so that pressure can be evenly applied to the circular paper holder.

[0058] Specifically, a pair of display screens 306 are installed on the support frame 301 for electrically connecting to the pressurizing cylinder 302, so that the real-time pressurizing value can be displayed on the groove 315, which is convenient for the staff to observe. A groove 315 is cut on the pressing column block 303 to facilitate the setting of the tension spring 307, so as to pull the uniform force rotating plate 304. The tension spring 307 is fixedly connected between the uniform force rotating plate 304 and the pressing column block 303, and is used to pull the uniform force rotating plate 304 to prevent the uniform force rotating plate 304 from shaking.

[0059] like Figure 1-Figure 4 As shown, a second shrinkage cavity 308 is excavated in the uniform force rotating plate 304 to provide space for the sliding of the second limit support block 309. The second limit support block 309 is slidably arranged in the second shrinkage cavity 308 to support the limit clamping block 310 to prevent the limit clamping block 310 from falling off. The second limit support block 309 is fixed with the limit clamping block 310 to clamp the clamping ring 311, so that the clamping ring 311 is not easy to move, and then the clamping ring 311 is used to clamp the multiple uniform force rotating plates 304 to prevent them from shaking.

[0060] Specifically, a plurality of second push springs 314 are fixedly connected between the side of the second limit support block 309 away from the limit clamping block 310 and the uniform force rotating plate 304, and are used to push the second limit support block 309, so that the second limit support block 309 drives the limit clamping block 310 to extend outward, and then the limit clamping block 310 clamps the clamping ring 311 to achieve the function of fixing the plurality of uniform force rotating plates 304. The plurality of limit clamping blocks 310 are buckled with the clamping ring 311, and are used to fix the plurality of uniform force rotating plates 304, so that the plurality of uniform force rotating plates 304 cannot be stretched, thereby reducing the force area of ​​the circular paper holder, and achieving the detection of multiple states.

[0061] like Figure 1-Figure 7 As shown, the positioning spraying mechanism 4 is installed in the operating support platform 201. The positioning spraying mechanism 4 is used to support the paper support, so as to facilitate the positioning and calibration of the paper support, and has the function of flaw detection and marking of the paper support. Among them, the positioning spraying mechanism 4 includes a support pile 401, which is used to provide support for fixing and positioning the circular paper support. A flaw detector 402 and a plurality of intelligent control valves 403 are installed on the support pile 401. The flaw detector 402 is used to perform flaw detection on the paper support, and can control the opening and closing of the intelligent control valve 403 in the first time after detection. The intelligent control valve 403 is used to control whether the paint is sprayed, and then it can mark the circular paper support when deformation or bulge is detected.

[0062] like Figure 1-Figure 7 As shown, a plurality of nozzles 404 are fixedly connected to the intelligent control valve 403 for spraying paint outward to achieve a marking effect. A storage tank 405 is also threadedly connected below the intelligent control valve 403 for storing paint, and a high-pressure gas is arranged inside, so that the intelligent control valve 403 can spray paint outward after opening. The flaw detector 402 includes a monitoring module, a positioning module and a control module.

[0063] Specifically, a plurality of protrusions 406 are fixed on the storage tank 405, which are used to facilitate the staff to rotate the storage tank 405, thereby facilitating the removal and installation of the storage tank 405. A support electric push rod 407 is installed below the support pile 401, which is used to control the lifting and moving of the lifting column 408, thereby facilitating the control of the lifting and moving of the support pile 401. A lifting column 408 is fixedly connected between the support electric push rod 407 and the support pile 401, which is used to support the lifting column 408 and drive the lifting and moving of the lifting column 408.

[0064] A method for using a quality inspection device for paper tray production, comprising the following steps:

[0065] S1. The staff places the produced circular paper holder on the support pile 401, and then starts multiple driving motors 208 at the same time, and drives the sliding support block 211 to move by rotating the driving screw 209, thereby driving multiple sliding positioning blocks 202 to move together, so that the multiple sliding positioning blocks 202 push the circular paper holder to move toward the central axis position of the operating support platform 201, and finally the multiple sliding positioning blocks 202 will push the circular paper holder to be located directly below the pressing column block 303;

[0066] S2. Moreover, the circular paper holder can be scooped up by the push shovel 203 and moved onto the push shovel 203. During the fixing process, the circular paper holder can push the fixing column 215 to retract into the storage slot. When all the fixing columns 215 are in contact with the trigger sheet 218, the positioning of the circular paper holder is completed. Then, the staff member rotates the downward control screw 205, and the downward clamping plate 204 is driven to descend by the downward control screw 205, so that the circular paper holder can be clamped and fixed.

[0067] S3, then, start the supporting electric push rod 407, so that the supporting electric push rod 407 controls the lifting column rod 408 to descend, so that there is no support under the circular paper holder, and then start the pressurizing cylinder 302, and control the pressing column block 303 to gradually descend through the pressurizing cylinder 302, so that the pressing column block 303 drives multiple uniform force rotating plates 304 to press on the circular paper holder, so as to exert force on the circular paper holder, so as to achieve the purpose of checking the quality of the paper holder;

[0068] S4. The lower end of the uniform force rotating plate 304 drives the stretching roller 313 to slide on the circular paper holder, so that the multiple uniform force rotating plates 304 can be stretched, thereby increasing the contact area of ​​the force applied to the circular paper holder and improving the detection effect. When the uniform force rotating plate 304 is blocked by the limit block 305 and cannot continue to rotate, the lowest point of the stretching roller 313 will be flush with the lowest point of the pressing column block 303, thereby ensuring the uniformity of the pressure applied to the circular paper holder.

[0069] S5. During the process of the pressure applied by the pressing column block 303 to the circular paper holder, the flaw detector 402 will continue to detect the bottom of the circular paper holder. When the applied pressure increases to a certain extent, the circular paper holder will be deformed, and the flaw detector 402 can detect it immediately.

[0070] S6. When the flaw detector 402 detects that the circular paper holder is deformed or bulged, it can quickly organize the data and determine the location of the bulge through the positioning module. Then, the intelligent control valve 403 in the corresponding area is activated through the control module, so that multiple nozzles 404 can spray paint outward, thereby achieving a marking effect and facilitating subsequent observation by staff.

[0071] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0072] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.

10. The method for using the quality inspection equipment for paper tray production according to claim 9, characterized in that: The following steps are involved: S1. The staff places the produced circular paper holder on the support pile, and then starts multiple driving motors at the same time, and drives the movement of the sliding support block by rotating the driving screw, thereby driving multiple sliding positioning blocks to move together, so that the multiple sliding positioning blocks push the circular paper holder to move toward the central axis position of the operating support platform, and finally the multiple sliding positioning blocks will push the circular paper holder to be located directly below the lower pressure column block; S2. Moreover, the circular paper holder can be scooped up by the push shovel and moved onto the push shovel. During the fixing process, the circular paper holder can push the fixing column to retract into the storage slot. When all the fixing columns are in contact with the trigger sheet, the positioning of the circular paper holder is completed. Then the staff rotates the downward control screw to drive the downward clamping plate to descend, thereby clamping and fixing the circular paper holder. S3, then, start the supporting electric push rod, so that the supporting electric push rod controls the lifting column rod to descend, so that there is no support under the circular paper support, and then start the pressurizing cylinder to control the pressing column block to gradually descend through the pressurizing cylinder, so that the pressing column block drives multiple uniform force rotating plates to press on the circular paper support, so as to achieve the purpose of checking the quality of the paper support; S4. The lower end of the uniform force rotating plate will drive the stretching roller to slide on the circular paper holder, so that the multiple uniform force rotating plates can be stretched out, thereby increasing the contact area of ​​the force applied to the circular paper holder and improving the detection effect. When the uniform force rotating plate is blocked by the limit block and cannot continue to rotate, the lowest point of the stretching roller will be flush with the lowest point of the lower pressure column block, thereby ensuring the uniformity of the pressure applied to the circular paper holder; S5. During the process of the pressure applied by the pressing column block to the circular paper support, the flaw detector will continue to detect the bottom of the circular paper support. When the applied pressure increases to a certain extent, the circular paper support will be deformed, and the flaw detector can detect it immediately. S6. When the flaw detector detects that the round paper tray is deformed or bulged, it can quickly organize the data and determine the location of the bulge through the positioning module. Then, the control module starts the intelligent control valve in the corresponding area, so that multiple nozzles can spray paint outward, thereby achieving a marking effect and facilitating subsequent observation by staff.
