DETAILED DESCRIPTION
[0028] A preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings.
[0029] To achieve the above purpose, the embodiment of the present invention adopts the following technical solution: Figure 1 , Figure 3 A valve seat ring finished product weight online automatic detection device includes a material receiving and steering mechanism 10, a weighing mechanism 20 and a screening mechanism 30. Further, the material receiving and steering mechanism is used to receive materials conveyed by a front-end device. The weighing mechanism is arranged at the output end of the material receiving and steering mechanism. It should be noted that the weighing mechanism can weigh the materials during the material conveying process, and the screening mechanism is arranged at the output end of the weighing mechanism. The screening mechanism can separate qualified products from unqualified products based on the weighing results of the weighing mechanism. When used The valve seat rings are transported online one by one to the material receiving and steering mechanism, and then are transported to the weighing mechanism after being transmitted by the material receiving and steering mechanism. When passing through the weighing table, the valve seat rings can be dynamically weighed using a weighing device such as an electronic scale, and the weighing results can be transported to the screening mechanism. The screening mechanism can remove abnormal parts whose weight does not meet the product specification value, specifically, the abnormal parts are pushed into the abnormal parts collection assembly, while the normal parts flow into the subsequent process. The present invention can realize online weighing and detection of valve seat rings, and can effectively remove abnormal parts to ensure that no products with unqualified weight flow out.
[0030] Reference Figure 2 As a preferred technical solution of this embodiment, the material receiving and steering mechanism includes a mounting frame 110 and a steering assembly, and the steering assembly is fixedly arranged on the inner side of the mounting frame. Further, the steering assembly includes a material receiving box 121, a feed baffle 122 and a slope 123. It should be noted that the side wall of the material receiving box 121 is provided with a feed end, and the feed baffle 122 is arranged at the feed end of the material receiving box, and the feed baffle 122 forms a through hole for feeding the valve seat ring into the material receiving box at the feed end position, and at the same time, a slope 123 inclined downward is provided at the bottom of the material receiving box. When in use, the valve seat ring conveyed to the rear through the previous process enters the material receiving box from the aforementioned through hole. Due to the existence of the slope, the valve seat ring will be conveyed outward in a manner of sliding downward along the slope. In this way, the valve seat ring conveyed in the vertical direction can be converted into horizontal conveying through the slope to ensure the stability of the valve seat ring conveying.
[0031] Furthermore, a transfer conveying mechanism is also provided at the output end of the material receiving and steering mechanism, and the transfer conveying mechanism includes a transfer frame 131, a transfer conveyor belt 132 and a guide assembly. Specifically, the transfer conveyor belt 132 is arranged on the top of the transfer frame, and the guide assembly is arranged on the top of the transfer conveyor belt, and the guide assembly is located on both sides of the steering assembly. At the same time, the guide assembly includes a mounting plate 133 and a guide plate 134. The mounting plate 133 is fixedly arranged at the two side edges of the transfer conveyor belt, and the mounting plate is distributed parallel to the conveying direction of the transfer conveyor belt. At the same time, the guide plate 134 is arranged on the inner side of the mounting plate, and the guide plate extends from the inner side of the mounting plate to the center position of the transfer conveyor belt, that is, the distance between the guide plates on both sides near the center position of the transfer conveyor belt becomes shorter and shorter, so that the valve seat ring transported by the steering assembly can be transported outward via the transfer conveyor belt, and under the guiding limit action of the guide plates on both sides of the guide assembly, the position of the valve seat ring is adjusted to adjust the valve seat ring to a suitable position, thereby facilitating transportation.
[0032] Reference Figure 3 As a preferred technical solution of this embodiment, the weighing mechanism includes a weighing base 210, an electronic scale unit 220, a weighing frame 230 and a weighing conveyor belt 240. The electronic scale unit 220 is arranged on the top of the weighing base, the weighing frame 230 is arranged on the top of the electronic scale unit, and the weighing conveyor belt 240 is arranged on the top of the weighing frame. At the same time, a position sensor 250 is also arranged at the output end of the weighing conveyor belt 240. When in use, the valve seat ring transported by the transfer conveyor belt is transported to the weighing conveyor belt backwards. Since the weighing conveyor belt is located on the top of the electronic scale unit, the valve seat ring can be weighed and detected during the movement of the valve seat ring along the load-bearing conveyor belt. At the same time, the weighing detection result can be transmitted to the screening mechanism, so that the screening mechanism can perform further operation processing. In addition, the presence of the position sensor can sense the position information of the valve seat ring passing through the weighing mechanism.
[0033] Reference Figure 4 As a preferred technical solution of this embodiment, the screening mechanism includes a screening frame 310, a screening conveyor belt 320, a pushing assembly and a collecting assembly. Furthermore, the screening conveyor belt 320 is arranged on the top of the screening frame, and the pushing assembly and the collecting assembly are arranged relatively to each other. Specifically, the pushing assembly is arranged at one side of the screening conveyor belt, and the collecting assembly is arranged at the other side of the screening conveyor belt. When in use, the valve seat ring transported by the weighing conveyor belt enters the screening conveyor belt. When it is detected that the weight of the valve seat ring does not meet the set requirement value, the pushing assembly at this time pushes the unqualified product out of the screening conveyor belt, and the pushed valve seat ring enters the collecting assembly for collection and processing, while the qualified products continue to be transported along the screening conveyor belt to the rear process.
[0034] Furthermore, the pushing assembly includes a pushing seat 331, a pushing cylinder 332 and a pushing rod 333. The pushing seat 331 is fixedly set on the side wall of the screening frame 310, the pushing cylinder 332 is set on the top of the pushing seat, and the pushing rod 333 is set at the output end of the pushing cylinder, and the pushing rod is distributed parallel to the conveying direction of the screening conveyor belt. When in use, when it is necessary to remove the unqualified valve seat ring detected by weighing, the pushing cylinder is actuated at this time, driving the pushing rod to move along the conveying direction perpendicular to the screening conveyor belt, thereby pushing out the unqualified products conveyed along the screening conveyor belt, and finally making the products fall into the collecting assembly.
[0035] Further, see Figure 5 The collecting assembly includes a collecting box 341 and a blanking plate 342. The collecting box 341 is fixedly arranged on the side wall of the screening frame 310, and the blanking plate 342 is arranged inside the collecting box 341. It should be noted that an inlet is provided on the side wall of the collecting box close to the screening frame, and the blanking plate is inclined from the inlet of the collecting box to the bottom of the box. When in use, the valve seat ring with unqualified weight pushed by the push rod enters the collecting box through the inlet when it moves out of the screening conveyor belt, and finally enters the bottom of the collecting box along the blanking plate for collection and processing.
[0036] Reference Figure 6 As a preferred technical solution of this embodiment, the valve seat ring finished product weight online automatic detection device also includes a feeding mechanism 40 arranged at the output end of the screening mechanism, the feeding mechanism includes a feeding frame 410, a feeding conveyor belt 420 and a feeding baffle 430, the feeding conveyor belt 420 is arranged on the top of the feeding frame, and the feeding baffle 430 is arranged on both sides of the feeding conveyor belt. When in use, the qualified products screened by the screening mechanism continue to be transported backward along the screening conveyor belt, and the qualified products further enter the feeding conveyor belt and are further transferred through the feeding conveyor belt. The existence of the feeding baffle can prevent the products transported by the feeding conveyor belt from falling.
[0037] Reference Figure 7 Furthermore, a material receiving mechanism 50 is also provided at the output end of the unloading mechanism, and the material receiving mechanism includes a material receiving seat 510, a material receiving turntable 520 and a material receiving frame 530. The material receiving turntable 520 is arranged on the top of the material receiving seat, and the number of material receiving frames is several, and the material receiving frame 530 is arranged on the top of the material receiving turntable. When in use, qualified products conveyed by the unloading mechanism are discharged into the material receiving frame. After a material receiving frame is full of material, the material receiving frame that is not full of material can be rotated to the unloading position of the unloading conveyor belt by rotating the material receiving turntable to achieve effective material receiving.
[0038] When in use, the valve seat rings are transported online one by one to the material receiving and steering mechanism, and then transported to the weighing mechanism after being transmitted by the material receiving and steering mechanism. The valve seat rings passing through the weighing table are dynamically weighed using an electronic scale unit, and the weighing results can be transported to the screening mechanism. The pushing component in the screening mechanism can remove abnormal parts whose weight does not meet the product specification value, specifically, the abnormal parts are pushed into the abnormal parts collection component, while the normal parts flow into the subsequent process, specifically, the qualified products enter the unloading conveyor belt of the unloading mechanism, and are transported to the receiving frame on the top of the receiving turntable through the unloading conveyor belt. The present invention can realize online weighing and detection of valve seat rings, and can effectively remove abnormal parts, ensuring that no products with unqualified weight flow out.
