Description

Technical Field

[0001] The present invention relates to the technical field of pressure difference measuring devices, and in particular to automatic quality inspection equipment for rubber product production. Background Art

[0002] Rubber products refer to the production of various rubber products using natural and synthetic rubber as raw materials. It also includes rubber products produced from waste rubber. The quality inspection of rubber products includes testing of their tensile properties, hardness and environmental adaptability.

[0003] Existing quality inspection devices for rubber products usually use a knife to dig out a portion of the surface of the rubber product, and then take samples from the inside of the rubber product for testing to obtain the pressure difference at the sampling point. However, the pressure difference at the sampling point is affected by temperature and frequency of use, which will produce certain errors, resulting in a certain impact on the accuracy of the test results. In addition, the sampling points of rubber products are mostly unable to be repaired later, resulting in the scrapping of the samples for sampling testing. At the same time, the process of inspecting the sampled materials using specific instruments is complicated and cannot quickly complete batch testing. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art that rubber products after sampling are difficult to repair later and the quality inspection process is complicated, batch inspection cannot be completed quickly, and the accuracy of the pressure difference at the inspection point is affected by the use conditions. An automatic quality inspection equipment for rubber product production is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic quality inspection equipment for rubber product production, including a screw-in assembly installed on a quality inspection frame, a downward pressure assembly provided on the screw-in assembly, and a central driving motor and a closed disk connected to the downward pressure assembly through a bracket assembly. A through hole is provided in the middle of the output shaft of the central driving motor, and a telescopic assembly is inserted into the inner wall of the through hole. A placement cavity is provided in the middle of the closed disk, and a central driving disk is inserted at the center of the placement cavity. An air cavity is provided inside the central driving disk, and the top of the air cavity is fixed to the output end of the central driving motor and is connected to the through hole. A transmission gear disc is hinged to the inner wall of the placement cavity through an axis, and the transmission gear disc is meshed with the central driving disk. A sampling knife is fixed to the bottom end of the transmission gear disc, and an outer peripheral cutting surface is provided on the outer side of the sampling knife, and a material discharge groove is provided on the inner side of the sampling knife.

[0007] Preferably, the central drive motor is coaxial with the closing disk, and a closing inclined surface is provided on the outer side of the closing disk.

[0008] Preferably, an extension sleeve is fixed to the top of the closing disk, and the outer surface of the extension sleeve is a polished surface.

[0009] Preferably, the precession assembly includes a precession motor fixed to the bottom of the quality inspection frame, the precession motor is coaxial with the central drive motor, and a fixed disk is fixed to the output end of the precession motor.

[0010] Preferably, the pressing assembly includes telescopic gas pressure rods fixed to the inner wall of the arc groove of the fixed disk, and there are three telescopic gas pressure rods.

[0011] Preferably, the bracket assembly includes a suspension frame fixed to the output end of the telescopic pneumatic rod, the bottom of the suspension frame is fixed to the top of the closing disk, a transverse arm is fixed to the side of the suspension frame, and one end of the transverse arm is fixed to the outside of the central drive motor.

[0012] Preferably, the telescopic assembly includes a punching rod plugged into the inner wall of the through hole, and an outer shell frame of the punching rod is fixed to the output end of the central drive motor.

[0013] Preferably, the sampling knife is arranged in an arc shape, and the long end of the sampling knife is the cutting end.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides a sampling knife. The sampling knife can complete the process of drilling and sampling under the drive of the screw-in motor. Sampling the sampling point by drilling can facilitate the later repair of the sampling point. At the same time, when the sampling knife is drilling and sampling, the central driving motor drives the central driving disk to change the opening angle of the sampling knife, so that irregular tooth-like patterns are formed on the side of the drilled hole, so that the fracture surface or bubble point of the detection point is fully exposed, which is convenient for later pressurization in the drilled hole, so that the gas is fully diffused into the layered surface or bubble point in the drilled hole, so that the measured value of the pressure difference at the detection point is more authentic and accurate. After the drilling is completed, the telescopic pneumatic rod can be used to inflate the drilled hole for pressure detection. In addition, the later repair is convenient, the pressure detection step is simple, and it is more suitable for large-scale quality inspection work.

[0016] 2. The present invention provides a peripheral cutting surface, which can form a triangular cutting surface on the outer side of the sampling knife. The hole wall cut by the triangular cutting surface can be corrugated. When the detection point is subjected to stamping detection, the corrugated hole wall has an uneven surface, which makes it easier for gas to diffuse to the rubber layer, exposing the internal delamination of the rubber product, thereby improving the accuracy and authenticity of the detected pressure difference.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances.

[0027] Example, see Figures 1 to 6 An automatic quality inspection equipment for rubber product production includes a screw-in assembly installed on a quality inspection frame. Furthermore, the screw-in assembly includes a screw-in motor 12 fixed to the bottom of the quality inspection frame. The screw-in motor 12 is coaxial with the central drive motor 1, and a fixed disk 13 is fixed to the output end of the screw-in motor 12.

[0028] A further advantage of adopting the above method is that the screw-in motor 12 serves as the power source for the sampling knife 7 to complete the drilling work. The screw-in motor 12 can drive the telescopic pneumatic rod 14, the suspension frame 15, the closing disk 2 and the sampling knife 7 connected to the closing disk 2 to complete the rotation movement through the fixed disk 13. The outer shell of the screw-in motor 12 is fixed to the bottom of the quality inspection frame.

[0029] A pressing assembly is provided on the screw-in assembly. Further, the pressing assembly includes a telescopic gas pressure rod 14 fixed to the inner wall of the arc groove of the fixed plate 13. There are three telescopic gas pressure rods 14.

[0030] A further advantage of adopting the above method is that the telescopic pneumatic rod 14 can drive the suspension frame 15 and the closing disk 2 connected to the suspension frame 15 to move up and down, so as to cooperate with the rotation of the central drive motor 1 to enable the sampling knife 7 to drill holes of different depths, so as to facilitate the subsequent inflation of the drilled hole to measure the pressure difference.

[0031] The downward pressure assembly is connected to the central drive motor 1 and the closing disk 2 through a bracket assembly. Furthermore, the bracket assembly includes a suspension frame 15 fixed to the output end of the telescopic pneumatic rod 14, the bottom of the suspension frame 15 is fixed to the top of the closing disk 2, and a horizontal arm 16 is fixed to the side of the suspension frame 15, and one end of the horizontal arm 16 is fixed to the outside of the central drive motor 1.

[0032] A further advantage of adopting the above arrangement is that the suspension frame 15 can connect the closing disc 2 with the telescopic pneumatic rod 14 , and the transverse arm 16 can connect the suspension frame 15 with the central drive motor 1 .

[0033] The central driving motor 1 is coaxial with the closing disk 2 , and a closing inclined surface 10 is provided on the outer side of the closing disk 2 .

[0034] The closed bevel 10 can make the closing disk 2 fit together with the connection between the borehole opening and the cavity, preventing the air cavity 5 from depressurizing when the borehole is inflated and pressurized under the action of the punching rod 17, affecting the accuracy of the pressure difference detection during pressurization. After the repair fluid is added to the borehole at the later stage, the punching rod 17 can be used to repeatedly impact the borehole to allow the repair fluid to fully diffuse into the stratification and bubble holes in the borehole to improve the repair integrity.

[0035] An extension sleeve 11 is fixed to the top of the closing disk 2 , and the outer surface of the extension sleeve 11 is a polished surface.

[0036] The outer surface of the extension sleeve 11 is a polished surface in order to further improve the sealing performance of the device and to avoid the accuracy of the detected pressure difference being affected by gas leakage when the borehole is inflated to measure the pressure difference.

[0037] A through hole is opened in the middle of the output shaft of the central drive motor 1, and a telescopic component is inserted into the inner wall of the through hole. Furthermore, the telescopic component includes a punching rod 17 inserted into the inner wall of the through hole, and the outer shell frame of the punching rod 17 is fixed to the output end of the central drive motor 1. The central drive motor 1 is an existing technology, and the specific reference can be made to the hollow shaft motor.

[0038] Further advantages of adopting the above method are: the output end of the punching rod 17 performs piston motion on the inner wall of the through hole of the central drive motor 1. First, by repeatedly inflating and pressurizing the drilled hole, the gas can be fully diffused into the rubber layer surface or bubble point to measure the pressure difference multiple times. Second, the punching rod 17 will generate heat during the high-frequency pressurization process to soften the rubber, so that the hidden layer surface in the rubber is quickly exposed, and the gas can quickly diffuse into the gap of the layer surface or the bubble point, avoiding the impact on the accuracy and authenticity of the detected pressure difference due to untimely or gradual exposure of the fracture surface.

[0039] A placement cavity 3 is provided in the middle of the closing disk 2, and a central drive disk 4 is inserted at the center of the placement cavity 3. An air cavity 5 is provided inside the central drive disk 4. The top of the air cavity 5 is fixed to the output end of the central drive motor 1 and is connected to the through hole. The inner wall of the placement cavity 3 is hinged with a transmission gear disk 6 through an axis. The transmission gear disk 6 is meshed with the central drive disk 4. A sampling knife 7 is fixed to the bottom end of the transmission gear disk 6. The sampling knife 7 is arranged in an arc shape, and the long end of the sampling knife 7 is a cutting end. The outer side of the sampling knife 7 is provided with an outer cutting surface 8, and the inner side of the sampling knife 7 is provided with a material discharge groove 9.

[0040] When drilling, the sampling knife 7 can drive the transmission gear disc 6 through the central drive motor 1 to change the opening angle of the sampling knife 7, so that holes of different diameters can be drilled. Due to the change in the opening angle of the sampling knife 7 during drilling, grooves of varying depths can also appear on the hole wall, which is beneficial for exposing hidden dangers in rubber products. The sampling knife 7 needs to be unfolded when working, so that the front end of the sampling knife 7 is located outside and the rear end can cross to cut the middle part.

[0041] When the present invention is in use, the sampling knife 7 is attached to the sampling surface of the rubber product, and the central drive motor 1, the telescopic pneumatic rod 14 and the screw-in motor 12 work together to drill holes of different diameters and depths as needed. The diameter of the drilled hole is fixed, and the diameter of the drilled hole changes according to the opening angle of the sampling knife 7 (the sampling knife 7 needs to be unfolded when working, so that the front end of the sampling knife 7 is located outside and the rear end can cross to cut the middle part);

[0042] After the drilling is completed, the closing disk 2 moves upward under the drive of the telescopic gas pressure rod 14, so that the closing inclined surface 10 abuts against the connection between the drill hole and the hole wall. The output end of the punching rod 17 performs a high-frequency piston motion on the inner wall of the through hole of the central drive motor 1, and the pressure in the drill hole is increased through the air cavity 5. When the drill hole continues to expand, the gas fully enters the gaps or bubble points of the rubber layer surface, making it convenient for the pressure detection device to record the pressure in the drill hole and obtain the pressure difference.

[0043] After the pressure difference test is completed, the repair liquid is added to the drill hole and the air cavity 5, and the repair liquid is repeatedly impacted by the output end of the punch rod 17, so that the repair liquid is fully diffused on the inner wall of the drill hole, as well as the rubber delamination and bubble holes, thereby improving the repair integrity of the rubber product. This process is simple to operate, takes a short test time, and is more suitable for large-scale testing.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
