Description

Technical Field

[0001] This utility model relates to the field of PDI testing instrument technology, and in particular to a PDI testing instrument with a separation sieve. Background Technology

[0002] A PDI (Pre-Delivery Inspection) instrument is a specialized device used to detect minute particles, surface defects, or perform pre-shipment quality checks on products. It is widely used in industrial manufacturing, pharmaceuticals, semiconductors, and automotive industries. Its core function is to identify contaminants, flaws, or assembly problems through optical, electronic, or mechanical means to ensure products meet quality standards.

[0003] Existing PDI (Powder Dispersion Index) analyzers for feed pellet testing can detect the pulverization rate of feed pellets. However, using a PDI analyzer requires placing a certain amount of feed pellets in the testing tank and rotating it a certain number of times before measuring the weight of the remaining solid feed pellets. Because the testing tank of the PDI analyzer lacks components for separating powder and collecting feed pellets, manual collection of the tested feed pellets is required. Furthermore, the existing test tank cover is flip-top, which hinders the collection of feed pellets. Therefore, existing PDI analyzers for detecting the pulverization rate of feed pellets are inconvenient to use. To address this, we provide a PDI analyzer with a separating sieve. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing PDI detectors, which cannot separate and collect the tested feed particles, and to provide a PDI detector with a separation sieve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a PDI detector with a separating sieve, comprising: a detector body, a collection mechanism on both sides of the detector body, the collection mechanism including a sieve, a draw plate at the bottom of the sieve, the draw plate being sleeved inside the detector body, a locking block fixedly connected to one side of the sieve, a locking groove on the locking block, a connecting block one at the bottom of the locking block, an angled block sleeved inside the connecting block one, the angled block being slidably connected to the connecting block one, a moving block at one end of the angled block, a limiting rod fixedly connected to the outer surface of the moving block, a spring one sleeved on the outer surface of the limiting rod, and a fixing mechanism at one end of the draw plate, the fixing mechanism including a connecting block two.

[0006] In a preferred embodiment, the draw plate is slidably connected to the detector body, the first connecting block is fixedly connected to the detector body, the moving block is fixedly connected to the bevel block, the moving block is sleeved inside the first connecting block, the moving block is slidably connected to the first connecting block, the limiting rod is sleeved inside the first connecting block, and the limiting rod is slidably connected to the first connecting block.

[0007] In a preferred embodiment, the two ends of the spring are respectively fixedly connected to the outer surface of the movable block and the inner wall of the connecting block. One end of the movable block is provided with an adjusting block, which is fixedly connected to the movable block. One end of the draw plate is provided with a pull rod, which is fixedly connected to the draw plate.

[0008] In a preferred embodiment, the second connecting block is fixedly connected to the detector body, and a locking rod is sleeved inside the second connecting block and the draw plate, and the locking rod is slidably connected to both the draw plate and the second connecting block.

[0009] In a preferred embodiment, a limiting ring is fitted onto the outer surface of the clamp rod, and the limiting ring is fixedly connected to the clamp rod.

[0010] In a preferred embodiment, a second spring is sleeved on the outer surface of the lever, and a pull block is fixedly connected to one end of the lever.

[0011] In a preferred embodiment, the two ends of the second spring are fixedly connected to the outer surface of the limiting ring and the inner wall of the second connecting block, respectively.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, through the inclusion of a collection mechanism, allows the detector to conveniently sieve the feed particles after testing a certain amount, thus separating the pulverized feed particles from the solid feed particles. The collected solid feed particles can then be weighed directly by the testing personnel to achieve the purpose of testing the pulverization rate of the feed particles. The invention incorporates a locking block and an angled block, with the locking block having a groove that fits into the angled block, allowing the locking block to engage with the angled block. Therefore, the sieve remains stable during use, and even if the testing tank of the detector rotates, it will not affect the sieve. Furthermore, a fixing mechanism is included, which works in conjunction with a drawer plate to fix the drawer plate in place, preventing it from detaching from the detector body during rotation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1-5As shown, this utility model provides a technical solution: a PDI detector with a separating sieve, comprising: a detector body 1, with collection mechanisms 2 on both sides of the detector body 1, each collection mechanism 2 including a sieve 21, a draw plate 22 at the bottom of the sieve 21, the draw plate 22 being sleeved inside the detector body 1, a locking block 23 fixedly connected to one side of the sieve 21, a locking groove 24 on the locking block 23, a connecting block 25 at the bottom of the locking block 23, a beveled block 26 sleeved inside the connecting block 25, the beveled block 26 being slidably connected to the connecting block 25, a moving block 27 at one end of the beveled block 26, a limiting rod 28 fixedly connected to the outer surface of the moving block 27, a spring 29 sleeved on the outer surface of the limiting rod 28, and the draw plate 22... One end is provided with a fixing mechanism 3, which includes a second connecting block 31, a drawer plate 22 slidably connected to the detector body 1, a first connecting block 25 fixedly connected to the detector body 1, a moving block 27 fixedly connected to an angled block 26, the moving block 27 being sleeved inside the first connecting block 25, the moving block 27 being slidably connected to the first connecting block 25, a limiting rod 28 being sleeved inside the first connecting block 25, the limiting rod 28 being slidably connected to the first connecting block 25, the two ends of a spring 29 being fixedly connected to the outer surface of the moving block 27 and the inner wall of the first connecting block 25 respectively, an adjusting block 201 being provided at one end of the moving block 27, the adjusting block 201 being fixedly connected to the moving block 27, and a pull rod 202 being provided at one end of the drawer plate 22, the pull rod 202 being fixedly connected to the drawer plate 22.

[0025] In this embodiment, by setting up a collection mechanism 2, the feed after rotation detection can be collected, and the solid feed particles can be directly weighed, thereby improving the ease of use of the detector body 1. A screen 21 is provided and placed at the discharge port of the detection tank of the detector body 1, so that when the detection tank is inverted, the screen 21 can separate the solid and powdery feed inside the detection tank. A drawer 22 is provided to prevent feed particles inside the detection tank from leaking out when it rotates, thus not affecting the detection results. The device is equipped with a locking block 23 and an angled block 26, and the locking block 23 has a locking groove 24 that fits into the angled block 26. This allows the locking block 23 and the angled block 26 to be engaged and connected, making it easy to install and remove the screen 21. In addition, a limiting rod 28 is provided, which can limit the spring 29 so that the spring 29 will not twist when compressed. This allows the spring 29 to better assist the moving block 27 and the angled block 26 in their use, so that the angled block 26 can be tightly engaged inside the locking block 23.

[0026] Example 2

[0027] like Figures 1-5As shown, connecting block 2 31 is fixedly connected to the detector body 1. A locking rod 32 is sleeved inside connecting block 2 31 and the draw plate 22. The locking rod 32 is slidably connected to both the draw plate 22 and connecting block 2 31. A limiting ring 33 is sleeved on the outer surface of the locking rod 32. The limiting ring 33 is fixedly connected to the locking rod 32. A spring 2 34 is sleeved on the outer surface of the locking rod 32. A pull block 35 is fixedly connected to one end of the locking rod 32. The two ends of the spring 2 34 are respectively fixedly connected to the outer surface of the limiting ring 33 and the inner wall of connecting block 2 31.

[0028] In this embodiment, a fixing mechanism 3 is provided to fix the drawer plate 22, preventing it from detaching from the detection tank of the detector body 1. A locking rod 32 is also provided, which, when sliding, drives the limiting ring 33 to slide. This limiting ring 33 compresses the second spring 34, causing it to generate elastic force. This elastic force then reacts on the limiting ring 33 and the locking rod 32, causing them to reset. Consequently, the locking rod 32 automatically engages with the interior of the drawer plate 22, preventing it from being pulled.

[0029] Working principle:

[0030] like Figures 1-5As shown, in use, a certain amount of feed pellets can be placed in the detection tank of the detector body 1. Then, the pull plate 22 is fitted into the inside of the detection tank of the detector body 1. At the same time, the pull block 35 is pulled, which drives the locking rod 32 to slide. When the locking rod 32 slides, the limiting ring 33 compresses the second spring 34, causing the second spring 34 to generate elastic force. After the pull plate 22 is installed, the pull block 35 can be released, and the elastic force of the second spring 34 will be released instantly. Then, the locking rod 32 is reset so that it can be tightly engaged inside the drawer plate 22. Next, the screen 21 is installed at the outlet of the inspection tank. During installation, the screen 21 will cause the locking block 23 to enter the connecting block 25, and the locking block 23 will press the angled block 26, causing it to slide into the connecting block 25. Simultaneously, the angled block 26 will cause the moving block 27 and the limiting rod 28 to slide simultaneously, and the moving block 27 can move within the limiting rod 28. With the cooperation of spring 29, spring 29 is compressed, generating elastic force. When the locking block 23 is fully inserted into the connecting block 25, the elastic force of spring 29 is released instantly, resetting the beveled block 26 so that it can engage with the slot 24 on the locking block 23. This stabilizes the screen 21. Then, the detector body 1 can be started, and the appropriate number of rotations of the detection tank can be set. After the detection is completed, the pull block 35 is pulled again, causing the locking rod 32 to engage with the pull plate 22. After detaching, use the pull rod 202 to pull the draw plate 22, so that the feed mixture after the detection tank is inverted can leak into the inside of the screen 21. Then slide the adjusting block 201, and use the adjusting block 201 to drive the moving block 27 to slide. The moving block 27 will drive the angled block 26 to disengage from the locking block 23, and then the screen 21 can be removed. Then gently sift the screen 21 so that the powdered feed can be separated from the screen 21. Finally, weigh the solid feed particles inside the screen 21 to obtain the powdering rate of this type of feed.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
