The side of the static resistance block opposite to the dynamic resistance block is in the shape of an inclined surface.

[0034] On the other hand, the present invention further provides a masterbatch detection method, using any of the masterbatch detection devices described above, comprising the following steps:

[0035] Step, pour the masterbatches of different batches to be tested from the feeding funnel into the interior of the cylindrical shell. The cylindrical shell is made of transparent material, so it can be observed whether the top port of the loading cavity on the loading column is aligned with the feeding channel. When aligned, pour the masterbatches from the feeding funnel into the corresponding loading cavity for temporary storage. As the cross shaft drives the test seat to rotate, the test seat drives the feeding gear to rotate through the test seat, thereby driving the loading column to rotate. Since the test seat rotates intermittently and the feeding gear at the end of the test seat stops when separated, the guide tube is located above the positioning hole. At the same time, the feeding gear drives the loading cavity on the loading column to rotate to the guide tube position, so that the masterbatch in the loading cavity at this position flows out from the guide tube and falls into the positioning hole at the end of the test seat. As the test seat rotates intermittently, the masterbatch feeding into the positioning holes at the ends of the test seats can be realized.

[0036] Step, when the test seat with masterbatch in the positioning hole rotates to the position below the test component along the cross shaft, the pressure supply hydraulic cylinder provides a preset pressure for the detection hammer head, so that the detection hammer head is inserted into the positioning hole to squeeze the masterbatch therein with the preset pressure, and the toughness test of the masterbatch is performed. After the test, the detection hammer head moves up and resets. During the downward movement of the detection hammer head, the positioning pressure block squeezes the upper sleeve, so that the upper sleeve moves down along the axial direction of the guide rod and drives the cleaning plate to move down and rotate at the same time, so that the scraper piece keeps rotating in the same horizontal plane as the bottom end of the detection hammer head and moves down synchronously with the detection hammer head, so that the scraper piece can rotate from one side of the detection hammer head to the other side position, and in the upward reset process of the detection hammer head, the scraper piece rotates in the opposite direction and moves up. At this time, the scraper piece can scrape the surface of the bottom end of the detection hammer head, peel off the broken masterbatch debris adhered to the bottom end of the detection hammer head, and make the masterbatch debris enter the positioning hole below through the guiding effect of the leakage hole, so that the bottom end of the detection hammer head will not be adhered to the masterbatch debris after the test is completed;

[0037] Step 1: After the test seat continues to rotate, it moves from the detection hammer head position to the arc cover body position. During this process, the driving convex block contacts the toggle rod and pushes it to move along the second arc hole, which can drive the nozzle head to move along the first arc hole, and at the same time push the arc piston cylinder to move along the piston rod direction, so that the sealing piston and the inner cavity of the arc piston cylinder move relative to each other, so that the gas in the arc piston cylinder is squeezed out from the nozzle head, so that the nozzle head can blow air vertically downward. During this process, the nozzle head is always located above the positioning hole, and the test bench has a through hole connected to the feed hole. , the masterbatch debris adhered to the inner wall of the positioning hole can be blown into the receiving box by wind force, so as to clean the inner wall of the positioning hole. When the toggle rod moves to its end position along the limit track, the thickness difference at the end of the limit track is utilized so that when the toggle rod moves to the end position of the limit track, it can automatically retract into the inner side of the arc cover body by the elastic thrust provided by the guide slider and separate from the driving protrusion. At this time, the jet head, the arc piston cylinder and the arc piston cylinder can be automatically reset by the elastic thrust provided by the arc spring, and the test seat can continue to rotate to perform the masterbatch detection work of the downward movement round.

[0038] Compared with the prior art, the technical effects of the present invention are:

[0039] (1) The masterbatch detection device provided by the present invention can complete the automated detection process of masterbatch loading, testing and unloading through the test component, positioning component and feeding component in the toughness test mechanism, thereby reducing the investment in manpower costs and realizing the processing of residual debris after the detection of unqualified masterbatch, thereby avoiding affecting the subsequent detection of masterbatch, improving the detection efficiency of masterbatch and ensuring the detection quality of masterbatch.

[0040] (2) The present invention installs a driving protrusion composed of an upper sleeve, a guide rod, a first spring, a rotating sleeve, a follower protrusion, a spiral track groove, a cleaning plate and a scraper sheet on the test seat. When the test seat rotates, the driving protrusion can not only push the toggle rod and the air jet head to move and clean the masterbatch debris remaining on the inner wall of the positioning hole, but also can peel off the masterbatch debris remaining at the bottom of the detection hammer head during the resetting process of the detection hammer head, so that no masterbatch debris remains on the positioning hole and the detection hammer head, thereby eliminating the influence of the masterbatch debris on the subsequent masterbatch toughness test and ensuring the quality of the subsequent masterbatch test.

[0041] (3) The present invention installs a sealing piston, an arc piston cylinder, a piston rod and an arc spring in the arc cover body to supply air to the nozzle, and then cooperates with the toggle rod and the limit track so that the driving protrusion can drive the nozzle to maintain a position above the positioning hole when the test seat rotates, and at the same time realizes blowing into the positioning hole. After reaching the preset position, the toggle rod automatically retracts and separates from the driving protrusion, completing the blowing and cleaning of the inside of the positioning hole while ensuring the smooth rotation of the test seat, making the cleaning work inside the positioning hole more convenient and efficient.

[0057] The positioning assembly 400 includes a cross shaft 402 and a test seat 401. The cross shaft 402 is rotatably connected to the middle of the test bench 100. A driving unit for driving the cross shaft 402 to rotate intermittently is arranged on the inner side of the test bench 100. The test seats 401 are multiple and fixedly connected to the outer wall of the cross shaft 402 at intervals. A positioning hole 403 for accommodating masterbatch is arranged at the end of the test seat 401 away from the cross shaft 402. A meshing tooth portion 404 is arranged on one side of the test seat 401 away from the cross shaft 402. In the prior art, the driving unit can be It is composed of a stepper motor and a controller to realize the intermittent rotation drive of the cross shaft 402, so that the cross shaft 402 can drive the test seat 401 at different positions to rotate to the position below the test component 300 and pause for a period of time to ensure that the test component 300 can smoothly detect the masterbatch. The masterbatch can be blocked and limited by the positioning hole 403 on the test seat 401. At the same time, as the test seat 401 rotates, the masterbatch in the positioning hole 403 can be driven to move to the position below the test component 300, so as to achieve the positioning of the masterbatch toughness detection.

[0058] Among them, the test component 300 includes a pressure supply hydraulic cylinder 301 and a detection hammer 302. The pressure supply hydraulic cylinder 301 is fixedly connected to the side of the top of the support frame 201, and the telescopic end of the pressure supply hydraulic cylinder 301 extends to the bottom of the support frame 201. The detection hammer 302 is fixedly connected to the bottom of the telescopic end of the pressure supply hydraulic cylinder 301, and the detection hammer 302 is located directly above the positioning hole 403 at the corresponding position. The pressure supply hydraulic cylinder 301 can be electrically connected to an external control terminal, and the pressure value provided on the pressure supply hydraulic cylinder 301 can be accurately controlled through the external control terminal to achieve toughness testing of masterbatch under different pressures.

[0059] Furthermore, since the masterbatch in the positioning hole 403 will be crushed after the extrusion test of the detection hammer head 302, the unqualified masterbatch will be crushed, which will result in the positioning hole 403 and the detection hammer head 302 having residual crushed masterbatch debris. If it is not cleaned in time, it will affect the subsequent toughness test of the masterbatch. Traditionally, it is cleaned manually. Therefore, in this embodiment, a cleaning mechanism is provided on the side of the top of the test bench 100, and the cleaning mechanism is used to clean the masterbatch debris remaining in the positioning hole 403. A material receiving box 101 is provided on the inner side of the test bench 100 and below the cleaning mechanism. A feeding hole 102 connected to the top of the test bench 100 is provided on one side of the top of the material receiving box 101 close to the test component 300. The material receiving box 101 A pad 103 is fixedly connected to the bottom of the inner cavity away from the feed hole 102, and a filter plate 104 is fixedly connected between the top of the pad 103 and the top of the inner wall of the receiving box 101 close to the feed hole 102. When the positioning hole 403 on the test seat 401 moves with the test seat 401 to the port position of the feed hole 102 on the receiving box 101, the cleaning mechanism is activated to peel off the masterbatch debris from the inner wall of the positioning hole 403, and enter the receiving box 101 from the feed hole 102 for collection. At the same time, in this process, the masterbatch that has passed the inspection will also fall from the feed hole 102 to the receiving box 101 due to gravity, and the screening effect of the filter plate 104 is used to achieve the separation between the complete masterbatch and the masterbatch debris, which is convenient for subsequent classification and collection;

[0060] Among them, the cleaning mechanism includes an arc cover body 406, a second arc hole 409, a limiting track 415 and a driving protrusion 405. A nozzle 407 is movably provided on the inner top of the arc cover body 406. The second arc hole 409 is opened on the side of the arc cover body 406 close to the cross shaft 402. A toggle rod 410 is slidably connected in the second arc hole 409. The toggle rod 410 is used to drive the nozzle 407 to move. The limiting track 415 is fixedly arranged on the inner wall of the arc cover body 406. One end of the toggle rod 410 is against the side wall of the limiting track 415. The limiting track 415 is used to guide the extension and contraction of the toggle rod 410. The driving protrusion 405 is fixedly connected to the end of the top of the test seat 401 close to the positioning hole 403.

As the test seat 401 continues to rotate, the driving protrusion 405 pushes the toggle rod 410 to move, and the toggle rod 410 drives the arc piston cylinder 411 and the nozzle head 407 to move synchronously, so that the relative movement between the sealing piston 412 and the arc piston cylinder 411 can be achieved, so that the gas in the arc piston cylinder 411 is pressed into the nozzle head 407 and discharged vertically downward, so that not only the synchronous movement of the nozzle head 407 and the positioning hole 403 is achieved, but also during this process, the nozzle head 407 continues to blow air into the positioning hole 403, and the positioning hole 403 is made to move by wind force. The masterbatch debris adhered to the inner wall is separated and falls into the receiving box 101. During the movement of the toggle rod 410, the guiding effect of the limit track 415 and the elastic thrust provided by the guide slider 418 to the toggle rod 410 are used to make the toggle rod 410 move to the inclined surface position at the tail end of the limit track 415, and then gradually retract into the arc cover 406 until it is completely separated from the driving protrusion 405. At this time, the test seat 401 can continue to rotate, and the toggle rod 410, the nozzle 407 and the arc piston cylinder 411 are reversely moved and reset by the elastic thrust provided by the arc spring 414, so as to clean the position of the positioning hole 403 on the subsequent test seat 401.

The upper sleeve 4001 is slidably sleeved on the outer wall of the guide rod 4002 and can move axially along the guide rod 4002. A first spring 4003 is fixedly connected between the upper sleeve 4001 and the guide rod 4002. One end of the cleaning plate 4007 is fixedly connected to a rotating sleeve 4004, and the rotating sleeve 4004 is rotatably connected to the upper sleeve 4001. At the bottom of the outer wall of the sleeve 4001, a follower protrusion 4005 is fixedly connected to the inner side of the rotating sleeve 4004, and the end of the follower protrusion 4005 extends to the inner side of the spiral track groove 4006 and is slidably connected to the inner wall of the spiral track groove 4006. An upwardly protruding scraper piece 4008 is provided on the side of the top of the cleaning plate 4007, and a leakage hole 4009 is provided at the end of the cleaning plate 4007 away from the rotating sleeve 4004. A positioning block 4010 is fixedly connected to the bottom of the outer wall of the detection hammer head 302, and the detection hammer head 302 provides downward pressure on the upper sleeve 4001 through the positioning block 4010; By setting the driving protrusion 405 into the above-mentioned structure, and cooperating with the setting of the positioning pressing block 4010 on the outer wall of the detection hammer head 302, the detection hammer head 302 can press the upper sleeve 4001 during the downward movement, and the rotating sleeve 4004 can guide the follow-up protrusion 4005 through the spiral track groove 4006 while the upper sleeve 4001 moves downward, so that the rotating sleeve 4004 can drive the cleaning plate 4007 to rotate while moving downward, so that the scraper sheet 4008 can always be kept at the horizontal plane position at the bottom end of the detection hammer head 302, and the detection hammer head 302 can be used for cleaning. Before the test, it is wiped. The side of the scraper piece 4008 close to the detection hammer head 302 can be a wiping brush structure. After the detection hammer head 302 is moved up and reset after the test is completed, the cleaning plate 4007 drives the scraper piece 4008 to scrape the bottom end of the detection hammer head 302, and the masterbatch debris remaining at the bottom is scraped off and dropped to the leakage hole 4009. The leakage hole 4009 can collect materials and guide them to fall into the positioning hole 403 below, thereby ensuring the surface cleanliness of the detection hammer head 302 before and after the detection, and avoiding affecting the toughness test of the masterbatch.

[0062] Example 2, based on Example 1, further discloses a feeding assembly 500, wherein the feeding assembly 500 includes a cylindrical shell 501 and a loading column 504, the cylindrical shell 501 is fixedly connected to the side of the bottom end of the support frame 201, the bottom of the side wall of the cylindrical shell 501 is fixedly connected to a guide tube 502, the bottom of the inner cavity of the guide tube 502 is provided with a guide slope 503, the loading column 504 is rotatably connected to the inner cavity of the cylindrical shell 501, the bottom of the loading column 504 extends to the bottom of the cylindrical shell 501 and is fixedly connected to a feeding gear 506, and the test seat 401 is engaged with the tooth portion 404 is meshed and connected with the feeding gear 506, and the side wall of the loading column 504 is provided with a loading cavity 505 connected with the guide tube 502; there are multiple loading cavities 505 and they are spaced apart in a circular array, the top of the loading cavity 505 is connected with the top of the loading column 504, and the bottom of the loading cavity 505 is connected with the side wall of the loading column 504, a feeding funnel 511 is fixedly provided on the top side of the support frame 201, and a feeding channel 512 connected with the feeding funnel 511 is opened at the top of the cylindrical shell 501, and the feeding channel 512 is located just above the top port of the loading cavity 505 at the corresponding position; When the test seat 401 rotates to the position of the feeding assembly 500, the test seat 401 meshes with the feeding gear 506 through the meshing tooth portion 404, thereby driving the loading column 504 to rotate at a preset angle, so that when the port of the loading chamber 505 reaches the position of the guide tube 502, the positioning hole 403 on the test seat 401 moves to the lower position of the guide tube 502. By setting the guide slope 503 at the bottom of the guide tube 502, the masterbatch can accurately enter the positioning hole 403, so that the masterbatch temporarily stored in the loading chamber 505 can be automatically fed into the positioning hole 403. , realizing automatic feeding and positioning of the masterbatch to be tested, and because there are multiple loading cavities 505 on the loading column 504, multiple batches of masterbatch to be tested can be classified and stored at the same time, so that the toughness test of multiple batches of masterbatch can be completed continuously, which is helpful to improve work efficiency; and the coordination of the feeding funnel 511 and the feeding channel 512 and the use of transparent material for the cylindrical shell 501 can facilitate the user to feed different batches of masterbatch into the loading cavities 505 at different positions on the loading column 504 from the position of the feeding funnel 511, making the feeding operation more convenient.

[0063] Furthermore, dynamic resistance blocks 507 are fixedly connected at the top of the outer wall of the loading column 504 and the corresponding positions of the loading chamber 505. The inner cavity of the cylindrical shell 501 is in a stepped shape with a wide top and a narrow bottom. A damping frame 508 is fixedly connected to the top of the inner wall of the cylindrical shell 501. Static resistance blocks 509 are slidably connected to the top and bottom of the inner side of the damping frame 508. A return spring 510 is fixedly connected between the static resistance block 509 and the damping frame 508. The side opposite to the dynamic resistance block 507 is in the shape of an inclined surface. When the loading chamber 505 is about to reach the position of the guide tube 502, the outer wall of the loading column 504 The dynamic resistance block 507 of the wall enters the position between the two static resistance blocks 509, and the elastic thrust provided by the reset spring 510 creates an extrusion force between the static resistance block 509 and the dynamic resistance block 507, thereby increasing the friction resistance between the two and forming a damping effect. In this way, when the meshing tooth portion 404 on the test seat 401 is separated from the feeding gear 506, the loading column 504 will not rotate a certain angle more due to inertia, so that the positioning of the loading cavity 505 on the loading column 504 can be more accurate, thereby making the feeding of the masterbatch in the positioning hole 403 more accurate.

[0064] In addition, this embodiment also provides a masterbatch detection method, using a masterbatch detection device in the above embodiment, including the following steps:

[0065] Step 1: Pour the masterbatch of different batches to be tested from the feeding funnel 511 into the interior of the cylindrical shell 501. The cylindrical shell 501 is made of transparent material, and it is possible to observe whether the top port of the loading cavity 505 on the loading column 504 is aligned with the feeding channel 512. When aligned, pour the masterbatch from the feeding funnel 511 into the corresponding loading cavity 505 for temporary storage. As the cross shaft 402 drives the test seat 401 to rotate, the test seat 401 drives the feeding gear 506 to rotate, which drives the loading column 504 to rotate. Since the test seat 401 is an intermediate The feeding gear 506 at the end of the test seat 401 stops rotating intermittently and is separated. At this time, the guide tube 502 is located above the positioning hole 403. At the same time, the feeding gear 506 drives the loading cavity 505 on the loading column 504 to rotate to the position of the guide tube 502, so that the masterbatch in the loading cavity 505 at this position flows out of the guide tube 502 and falls into the positioning hole 403 at the end of the test seat 401. As the test seat 401 rotates intermittently, the masterbatch feeding into the positioning holes 403 at the ends of multiple test seats 401 can be realized;

[0066] Step 2, when the test seat 401 with the masterbatch in the positioning hole 403 rotates to the position below the test assembly 300 along with the cross shaft 402, the pressure supply hydraulic cylinder 301 provides a preset pressure for the detection hammer head 302, so that the detection hammer head 302 is inserted into the positioning hole 403 to squeeze the masterbatch therein with a preset pressure, and the toughness test of the masterbatch is performed. After the test, the detection hammer head 302 moves up and resets. During the downward movement of the detection hammer head 302, the positioning pressing block 4010 squeezes the upper sleeve 4001, so that the upper sleeve 4001 moves downward along the axial direction of the guide rod 4002, drives the cleaning plate 4007 to move downward and rotates at the same time, so that the scraper sheet 4008 is kept The scraper 4008 rotates in the same horizontal plane as the bottom end of the detection hammer 302 and moves downward synchronously with the detection hammer 302, so that the scraper 4008 can rotate from one side of the detection hammer 302 to the other side. During the upward reset process of the detection hammer 302, the scraper 4008 rotates in the opposite direction and moves upward. At this time, the scraper 4008 can scrape the surface of the bottom end of the detection hammer 302, peel off the broken masterbatch debris adhered to the bottom end of the detection hammer 302, and guide the masterbatch debris through the leakage hole 4009 into the positioning hole 403 below, so that the bottom end of the detection hammer 302 will not be adhered to the masterbatch debris after the test is completed.

[0067] Step 3, the test seat 401 continues to rotate and moves from the position of the detection hammer head 302 to the position of the arc cover body 406. During this process, the driving block 405 contacts the toggle rod 410 and pushes it to move along the second arc hole 409, which can drive the nozzle 407 to move along the first arc hole 408, and at the same time push the arc piston cylinder 411 to move along the direction of the piston rod 413, and the sealing piston 412 and the inner cavity of the arc piston cylinder 411 move relative to each other, so that the gas in the arc piston cylinder 411 is squeezed out from the nozzle 407, so that the nozzle 407 can blow air vertically downward. During this process, the nozzle 407 is always located above the positioning hole 403, and the test bench 100 has a position corresponding to the feed hole 102. The connected through hole can utilize wind force to blow the masterbatch debris adhered to the inner wall of the positioning hole 403 into the receiving box 101, so as to clean the inner wall of the positioning hole 403. When the toggle rod 410 moves to its end position along the limiting track 415, the thickness difference at the end of the limiting track 415 is utilized to make the toggle rod 410 move to the end position of the limiting track 415 and can automatically retract into the inner side of the arc cover body 406 through the elastic thrust provided by the guide slider 418, and separate from the driving protrusion 405. At this time, the nozzle 407, the arc piston cylinder 411 and the arc piston cylinder 411 can be automatically reset by the elastic thrust provided by the arc spring 414, and the test seat 401 can continue to rotate to perform the masterbatch detection work of the downward movement round.
