Description

Technical Field

[0001] The invention relates to the technical field of fast granulator, and in particular to a testing system and a testing method for components of a fast granulator. Background Art

[0002] Rapid granulator is widely used in pharmaceutical, chemical and food industries with good effect. After the processed raw materials enter the feed port, they fall into the conical screen. The rotating rotary knife exerts a swirling effect on the raw materials and throws the particles to the screen surface with centrifugal force. At the same time, the high-speed rotation of the rotary knife and the screen surface produce a shearing effect. The particles are crushed into small particles between the rotation and the screen and discharged through the screen. The size of the crushed particles is adjusted by the number of screens, the distance between the rotary knife and the screen, and the speed of rotation. It can be seen that the screen and the rotary knife are extremely important components of the rapid granulator.

[0003] During the use of the rapid granulator, the material inside the screen generates an impact force on the screen under the centrifugal force of the rotating knife, and the screen has to withstand the extrusion force of the material under the shearing effect, which makes the screen with poor strength easy to deform. Since the distance between the rotating knife and the screen determines the size of the particles to be crushed, the deformed screen body makes it impossible for the rapid granulator to control the particle size. Therefore, it is necessary to test the strength of the screen.

[0004] Therefore, it is necessary to provide a testing system and a testing method for fast granulator components, which can achieve the effect of continuous testing. Summary of the invention

A plurality of screen bodies 6 are stacked and placed in the loading barrel 2. The loading barrel 2 is used to load the screen bodies 6 into the support seat 9 in sequence.

[0049] The rotating workbench 7 drives the screen body 6 to pass through the lower side of the loading barrel 2, the test assembly and the visual inspection mechanism 5 in sequence;

[0050] The test assembly includes a test wheel 101, a rotating shaft 102 is provided on one side of the test wheel 101, a pressing plate 103 is provided on the upper end of the rotating shaft 102, a pressing ring 104 is fixedly connected to the lower end of the pressing plate 103, and a lifting assembly is provided on the upper side of the pressing plate 103.

[0051] The visual inspection mechanism 5 performs visual inspection on the screen body 6 after the test.

[0052] When the test work is needed, firstly, a batch of screen bodies 6 are placed in the loading barrel 2 manually, and then the support seat 9 can be driven to move by the rotating workbench 7. The support seat 9 first moves to the lower side of the loading barrel 2, and the screen bodies 6 are sequentially unloaded into the support seat 9 through the loading barrel 2 for loading. The screen bodies 6 fall into the support seat 9, and the upper edge portion is supported by the support seat 9; then the rotating workbench 7 drives the support seat 9 and the screen body 6 to move to the lower side of the test assembly, and the pressing plate 103 is driven down by the lifting assembly, so that the test wheel 101 extends into the inside of the screen body 6, and the pressing ring 104 presses the upper edge portion of the screen body 6 onto the support seat 9; then the test wheel 101 is driven to move in a circular manner by the rotating shaft 102, so that the test The wheel 101 continuously performs rolling tests on the inner side of the screen body 6, thereby simulating the squeezing effect of the internal powder on the screen body 6 caused by the high-speed rotation of the rotary knife; after the test, the screen body 6 is moved to the lower side of the visual inspection mechanism 5, and the deformation of the screen body 6 after the test is detected by the visual inspection mechanism 5 (the visual inspection mechanism is a prior art, so it is not described in detail here), so as to judge whether the use strength of the screen body 6 is qualified, and the inspection of the screen body 6 can be completed, and then the staff will remove the screen body 6 after the inspection, and the support seat 9 will be moved to the lower side of the upper barrel 2 again to carry out a new round of inspection work, so as to realize the continuous inspection of a batch of screen bodies 6, greatly improve the work efficiency, and is suitable for large-scale inspection;

[0053] Preferably, four support seats 9 are provided so that the four processes of loading, testing, detecting and taking out can be carried out simultaneously, thereby further improving the working efficiency;

[0054] Preferably, the test wheel 101 is made of rubber material, so as to avoid serious damage to the screen body 6 during the test, and can further simulate the softness of the material, which is highly practical.

[0055] There are several groups of test wheels 101, and several test wheels 101 are symmetrically distributed on both sides of the lower end of the rotating shaft 102. Limiting grooves 105 are opened on both sides of the lower end of the rotating shaft 102. A pair of spring contraction rods 106 are penetrated through the inner side of the limiting grooves 105. The two ends of the spring contraction rods 106 are connected to special-shaped blocks 107. Several test wheels 101 are rotatably connected to one side of the special-shaped block 107 and are distributed in a stepped shape.

[0056] Preferably, in order to further increase the test pressure on the screen body 6 to achieve a more comprehensive test result, a special-shaped block 107 is provided. Specifically, several test wheels 101 on both sides are distributed in a stepped manner on a pair of special-shaped blocks 107, so that the test wheels 101 are adapted to the internal shape of the conical screen body 6. In the initial state, the spring contraction rod 106 makes the pair of special-shaped blocks 107 close to the limiting groove 105, thereby facilitating the extension of several test wheels 101 into the screen body 6. Then, the rotating shaft 102 can drive the pair of special-shaped blocks 107 to rotate, so that several test wheels 101 are fitted inside the screen body 6 for rolling. Then, by driving the pair of special-shaped blocks 107 to move relative to each other, several test wheels 101 on both sides move outward, and while rolling along the inside of the screen body 6, outward pressure is applied to it, thereby further increasing the test pressure of the screen body 6, so as to simulate the long-term squeezing of the screen body 6 by the material during actual use, quickly detect the use intensity of the screen body 6, and improve work efficiency.

[0057] The upper end of the limiting groove 105 is slidably matched with a triangular wedge block 108, and the upper end of the special-shaped block 107 is provided with an inclined surface, and the triangular wedge block 108 is adapted to the inclined surface of the special-shaped block 107. The lower end of the pressing plate 103 is provided with a plurality of guide telescopic rods 109, and the lower end of the guide telescopic rod 109 is provided with a lifting ring 110. The lifting ring 110 is sleeved on the outer side of the rotating shaft 102 and is threadedly connected thereto, and the lower end of the lifting ring 110 is rotatably connected to the triangular wedge block 108.

[0058] Preferably, when it is necessary to drive the special-shaped block 107 to move, the rotating shaft 102 is rotated, and the rotating shaft 102 is threadedly connected to the lifting ring 110, and under the guiding action of the guide telescopic rod 109, the lifting ring 110 is driven by the rotating shaft 102 to move downward, and the lifting ring 110 pushes the triangular wedge block 108 to descend, and the triangular wedge block 108 pushes the special-shaped block 107 along the inclined surface, so that a pair of special-shaped blocks 107 can be separated from each other. At the same time, the rotating shaft 102 also drives the special-shaped block 107 to rotate, so that the test wheel 101 rolls, so that the test wheel 101 rolls and the screen body 6 is applied with pressure, and the two have good synchronization and high degree of automation. When the lifting ring 110 drops to a predetermined height, it means that the test standard pressure value is applied to the screen body 6, and the rotating shaft 102 can be reset and rotated, so that the special-shaped block 107 and the test wheel 101 are reset, and the test is completed.

[0059] The lifting assembly includes a plurality of guide telescopic columns 3, the upper ends of the guide telescopic columns 3 are connected to the top plate 1, the lower ends of the guide telescopic columns 3 are connected to the pressing plate 103, the upper end of the top plate 1 is fixedly connected to a motor component 4, the lower end of the motor component 4 is driven by a screw rod 301, the lower end of the screw rod 301 is threadedly connected to a nut sleeve 302, and the nut sleeve 302 is used to drive the pressing plate 103 to rise and fall.

[0060] Preferably, when the test wheel 101 and the pressing ring 104 need to be driven to rise and fall, the motor 4 drives the screw 301 to rotate, and the screw 301 is threadedly connected to the nut sleeve 302. Under the guidance of the guide telescopic columns 3, the nut sleeve 302 pushes the pressing plate 103 to rise and fall.

[0061] The nut sleeve 302 passes through the pressing plate 103 and is rotatably connected thereto. The lower end of the nut sleeve 302 is fixedly connected to the upper end of the rotating shaft 102. A fixing ring 309 is fixedly connected to the outer side of the nut sleeve 302. A spring telescopic rod 305 is provided at the lower end of the fixing ring 309. A brake ring 306 is provided at the lower end of the spring telescopic rod 305. A pair of clamping plates 307 are fixedly connected to the lower end of the brake ring 306. An annular clamping slot 308 is provided at the upper end of the pressing plate 103. The clamping plate 307 is adapted to the annular clamping slot 308.

[0062] A step groove is provided on the inner side of the annular card slot 308, and a driving ring 304 is provided in the step groove. The driving ring 304 slides with the nut sleeve 302, and an extension rod 310 is fixedly connected to the inner side of the driving ring 304. A plurality of vertical grooves are penetrated through the lower side of the nut sleeve 302, and the extension rod 310 passes through the vertical grooves and slides with the extension rod 310. A disk 311 is provided on the inner side of the nut sleeve 302, and the disk 311 is located on the lower side of the extension rod 310. A connecting rod 312 is fixedly connected to the upper end of the disk 311. A hollow groove is provided at the upper end of the screw rod 301, and the upper end of the connecting rod 312 passes through the hollow groove and is fixedly connected to a baffle plate 313.

[0063] Preferably, in the initial state, the spring telescopic rod 305 keeps a distance between the brake ring 306 and the fixing ring 309, so as to ensure that the clamping plate 307 is always clamped in the annular clamping slot 308, so that the nut sleeve 302 is fixed. At this time, the screw rod 301 rotates to drive the nut sleeve 302 to move downward, and the nut sleeve 302 pushes the pressing plate 103, so that the test wheel 101 can be lowered to the inside of the screen body 6, and the pressing ring 104 presses the screen body 6. Then, the brake ring 306 is driven to rise, so that the clamping plate 307 is away from the annular clamping slot 308, so that the nut sleeve 302 loses its restriction and can rotate. At this time, the screw rod 301 continues to rotate, which can drive the nut sleeve 302 to rotate synchronously, and the nut sleeve 302 can drive the rotating shaft 102 to rotate, thereby driving a plurality of test wheels 101 to roll along the inside of the screen body 6 while applying outward pressure to it for detection. That is to say, the pressing plate 103 can be lowered by rotating the screw rod 301, and the detection function can be further realized, with a high degree of automation.

[0064] Preferably, when it is necessary to drive the brake ring 306 to rise, a connecting rod 312 and a driving ring 304 are provided. Specifically, in the initial state, the disc 311 falls on the upper end surface of the rotating shaft 102, and the baffle plate 313 is also at the uppermost end of the hollow groove. At this time, the card plate 307 is inserted into the annular card slot 308, and the screw 301 drives the pressing plate 103 to descend, so that the baffle plate 313 also moves downward from the upper end of the hollow groove until the baffle plate 313 moves to the lowermost end of the hollow groove, and the height positions of the baffle plate 313, the connecting rod 312 and the disc 311 remain unchanged, and the pressing plate 103 continues to move downward, and the disc 311 contacts the extension rod 310, so that the driving ring 304 also maintains its height. The driving ring 304 limits the height of the clamping plate 307 to remain stationary, so that the pressing ring 104 and the annular clamping slot 308 are lowered separately until the clamping plate 307 is completely separated from the annular clamping slot 308. At this time, the pressing ring 104 also presses the screen body 6. Since the clamping plate 307 is completely separated from the annular clamping slot 308, when the screw rod 301 continues to rotate, it will directly drive the nut sleeve 302 to rotate, and the rotating shaft 102 can be driven to rotate to perform the test work. In other words, no additional driving components or control programs are required. Only the rotation of the screw rod 301 can independently complete the descent of the test wheel 101 and perform the rolling test on the screen body 6, thereby saving costs.

[0065] Preferably, a plurality of brake blocks 401 are fixedly connected to the lower end of the pressing plate 103, and the brake blocks 401 limit the highest position of the lifting ring 110. When resetting is required, the screw rod 301 is reversed to first drive the rotating shaft 102 to reverse, thereby driving the lifting ring 110 to rise and reset. When contacting with the brake block 401, the lifting ring 110 is reset and cannot continue to rise, causing the rotating shaft 102 to be unable to continue to reverse, so that the nut sleeve 302 is fixed. At this time, the screw rod 301 is reversed alone, which can directly drive the nut sleeve 302 to rise and reset, and also allows the clamping plate 307 to be re-inserted into the annular clamping slot 308 to prepare for the next work.

[0066] A hollow ring 201 is fixedly connected to the lower side of the upper barrel 2, and a plurality of spring telescopic rods 202 are arranged on the inner side of the hollow ring 201. An arc-shaped inclined block 203 is arranged at one end of the spring telescopic rod 202. The arc-shaped inclined block 203 passes through the upper barrel 2 and slides with it. The inclined surface of the arc-shaped inclined block 203 faces upward, and the plurality of arc-shaped inclined blocks 203 limit the falling of the screen body 6.

[0067] The four sides of the upper barrel 2 are provided with square openings, and slide plates 204 are slidably fitted in the square openings. The slide plates 204 are used to press down a plurality of screen bodies 6 .

[0068] Preferably, when a batch of screen bodies 6 are placed in the loading barrel 2, a plurality of arc-shaped inclined blocks 203 are arranged at their lower ends for blocking. When a single screen body 6 needs to be screened out and unloaded, a plurality of screen bodies 6 are pressed down by the slide plate 204. The inclined surface of the arc-shaped inclined block 203 is subjected to pressure and displaced toward the outer hollow ring 201, so that the screen body 6 at the lower end falls. Then, under the resetting action of the spring telescopic rod 202, the arc-shaped inclined block 203 is reset, and the upper screen body 6 is re-stuck to limit its falling, thereby realizing the single screening and falling of the screen body 6.

[0069] A plurality of guide plates 207 are fixedly connected to the outer side of the upper barrel 2. The guide plates 207 are arranged at both ends of the square opening. An inclined opening 205 is arranged on the upper side of the square opening. An inclined groove is opened on the inner side of the upper end of the guide plate 207. The inclined opening 205 and the inclined groove are connected to each other. Limiting rods 206 are fixedly connected to both ends of the slide plate 204. When the limiting rods 206 are at the upper end of the inclined groove, the inner end surface of the slide plate 204 is flush with the inner wall of the upper barrel 2.

[0070] Preferably, in order to prevent the slide plate 204 from being inside the upper barrel 2 and thereby obstructing the subsequent feeding of the screen body 6, an inclined mouth 205 and an inclined groove are provided.
