[0029] See also Figure 1-Figure 7 , the present invention provides three technical solutions:

[0030] Embodiment 1

[0031] See also Figure 1 In an embodiment of the present invention, a quality inspection device for preparing a new material plastic barrel includes a test bench 1, a protective component 2 for preventing plastic barrel fragments from splashing is arranged on the upper part of the test bench 1, and an L-shaped seat 3 is installed on the back of the test bench 1, and a moving sleeve 4 is arranged on the outer longitudinal sliding sleeve of the L-shaped seat 3, and a crossbeam 6 is arranged on one side of the moving sleeve 4, and a test piece 7 is arranged on the side of the crossbeam 6 away from the moving sleeve 4, and a test drive component 5 for driving the moving sleeve 4 to move longitudinally is arranged on the side of the L-shaped seat 3 away from the crossbeam 6.

[0032] See also Figure 1-Figure 2In the embodiment of the present invention, the protection component 2 includes a concave protection plate 21 that is longitudinally slidably inserted into the upper part of the test bench 1 and a lifting hydraulic cylinder 22 installed on the side of the test bench 1 away from the L-shaped seat 3. A limit plate 23 is provided at the upper edge of the side of the concave protection plate 21 away from the L-shaped seat 3. The output shaft of the lifting hydraulic cylinder 22 is connected to the bottom of the limit plate 23. A connecting rod 24 is hinged at the inner upper edge of the concave protection plate 21, and a scraper 25 is hinged at one end of the connecting rod 24 away from the inner side of the concave protection plate 21.

[0033] See also Figure 1-Figure 2 In the embodiment of the present invention, when the concave protective plate 21 is fully raised to the upper part of the test bench 1, the scraper 25 is located exactly on the inner side of the concave protective plate 21. When the concave protective plate 21 is lowered to make the bottom of the limit plate 23 fit the upper part of the test bench 1, the scraper 25 is located exactly on the upper edge of one side of the test bench 1 close to the L-shaped seat 3.

[0034] In the above scheme: the plastic barrel to be tested is placed on the test bench 1, and then the lifting hydraulic cylinder 22 drives the limit plate 23 to move upward, and the limit plate 23 drives the concave protective plate 21 to move upward, and the concave protective plate 21 blocks the plastic barrel, so that during the compression test, the crushed plastic barrel fragments will not splash to personnel, and while the concave protective plate 21 moves upward, the connecting rod 24 will drive the scraper 25 to move toward the inner side of the concave protective plate 21, so that the scraper 25 moves to the position inside the concave protective plate 21, so that it does not affect the compression test of the plastic barrel, when the test is completed, the concave protective plate 21 moves downward, and the concave protective plate 21 will cause the connecting rod 24 to drive the scraper 25 to move away from the inner side of the limit plate 23, and the scraper 25 will scrape off the plastic barrel debris on the test bench 1, and clean the table top of the test bench 1.

[0035] For further information, see Figure 1-Figure 2 In the embodiment of the present invention, the protection component 2 also includes a limit shaft 26 arranged at the edge of the scraper 25 away from the connecting rod 24 and a limit seat 27 arranged on one side of the L-shaped seat 3. The end of the limit seat 27 away from the L-shaped seat 3 is laterally slidably sleeved on the outside of the limit shaft 26. When the scraper 25 moves, its bottom is always in contact with the upper part of the test bench 1. When the scraper 25 moves, the limit shaft 26 will slide on the limit seat 27 to limit the scraper 25.

[0036] The second embodiment is different from the first embodiment in that:

[0037] See also Figure 3-Figure 4In the embodiment of the present invention, the test piece 7 includes a test seat 71 arranged at the end of the beam 6 away from the movable sleeve 4, an open groove 72 is arranged at the bottom of the test seat 71, and a test hydraulic cylinder 73 is installed on the upper part of the test seat 71, the output shaft of the test hydraulic cylinder 73 is located in the test seat 71 and is horizontally connected with a movable bar 74, and a test spike 75 corresponding to the open groove 72 is arranged at the lower part of the movable bar 74.

[0038] See also Figure 3-Figure 4 In the embodiment of the present invention, the bottom of the test seat 71 is provided with through limit grooves 77 at both sides of the opening groove 72, and moving blocks 78 are provided in the two limit grooves 77. The moving blocks 78 are connected to the test seat 71 in a transverse sliding manner, and a fixed shaft 79 is connected in the limit groove 77. The moving blocks 78 are transversely slidably sleeved on the outside of the fixed shaft 79. The upper sides of the two moving blocks 78 are located in the test seat 71 and are hinged with adjustment rods 711. The ends of the two adjustment rods 711 away from the moving blocks 78 are hinged to the bottom of the moving bar 74 and are respectively located on both sides of the test spike 75. The lower sides of the two moving blocks 78 are provided with pressure plates 710.

[0039] See also Figure 3-Figure 4 In the embodiment of the present invention, when the lower end of the test spike 75 extends out of the opening slot 72 and is lower than the position of the pressure plate 710, the two pressure plates 710 just open the opening slot 72 at the bottom of the test seat 71. When the two pressure plates 710 are combined to close the opening slot 72 at the bottom of the test seat 71, the test spike 75 is just located in the test seat 71.

[0040] In the above scheme: when the two pressing plates 710 are combined, the plastic barrel can be subjected to a flat pressure test, such as Figure 3 As shown, when point pressure is needed, the test hydraulic cylinder 73 drives the moving bar 74 to move downward, and the moving bar 74 causes the adjusting rod 711 to drive the moving block 78 to slide on the fixed shaft 79, so that the two pressing plates 710 open the opening slot 72 at the bottom of the test seat 71. When the moving bar 74 moves downward, it drives the test spike 75 to move downward, so that the lower end of the test spike 75 passes through the opening slot 72 and is lower than the position of the pressing plate 710. In this way, the test spike 75 can perform point pressure test on the plastic barrel.

[0041] For further information, see Figure 2-Figure 3 In the embodiment of the present invention, guide grooves 76 are provided on both sides of the interior of the test seat 71, and the two ends of the movable bar 74 are respectively provided in the two guide grooves 76 and are longitudinally slidably connected with the test seat 71. The guide grooves 76 play a guiding and limiting role for the movement of the movable bar 74.

[0042] Embodiment 3 is different from Embodiment 1 in that:

[0043] See also Figure 5-Figure 7In the embodiment of the present invention, the test drive assembly 5 includes a fixed seat 51 arranged at the upper edge of the side of the L-shaped seat 3 away from the crossbeam 6, a servo motor 52 is installed on the upper part of the fixed seat 51, the output shaft of the servo motor 52 is located at the lower part of the fixed seat 51 and is connected with a screw 53, the outer part of the screw 53 is screwed with a moving seat 54 through a thread, and the moving seat 54 is provided with an active cavity 55 on the side close to the moving sleeve 4, a positioning block 56 is connected to the active cavity 55 in a transverse sliding manner, one side of the positioning block 56 is located in the active cavity 55 and is integrally formed with an iron plate 57, a side of the iron plate 57 away from the positioning block 56 is fixedly connected to the inner side of the active cavity 55 by two springs 58, and a magnetic block 59 is provided on the inner side of the active cavity 55 at a position between the two springs 58.

[0044] See also Figure 5-Figure 7 In the embodiment of the present invention, when the spring 58 is in an elastic reset state, the side of the positioning block 56 away from the iron plate 57 extends out of the movable cavity 55, and the side of the movable sleeve 4 away from the crossbeam 6 is provided with a positioning groove 41 corresponding to the positioning block 56, so that the side of the positioning block 56 away from the iron plate 57 can be just inserted into the positioning groove 41 on the movable sleeve 4, and the suction force of the magnetic block 59 on the iron plate 57 is greater than the elastic force of the spring 58. When the positioning block 56 is completely moved into the movable cavity 55, the side of the positioning block 56 away from the iron plate 57 just leaves the positioning groove 41 on the movable sleeve 4.

[0045] See also Figure 5-Figure 7 In the embodiment of the present invention, an infrared transmitter 510 is embedded in the side of the positioning block 56 away from the iron plate 57, and an infrared receiver 42 corresponding to the infrared transmitter 510 is arranged on the inner side of the positioning groove 41. The infrared receiver 42 transmits the signal emitted by the infrared transmitter 510 to an external control device. After the infrared receiver 42 receives the signal of the infrared transmitter 510, the positioning block 56 can be aligned with the positioning groove 41, so that the positioning block 56 can be inserted into the positioning groove 41 conveniently.

[0046] In the above scheme: when it is necessary to perform a continuous pressure test on the plastic barrel, the servo motor 52 drives the screw 53 to rotate, and the screw 53 drives the moving seat 54 to move. When the infrared transmitter 510 on the positioning block 56 corresponds to the infrared receiver 42 inside the positioning groove 41, the signal emitted by the infrared transmitter 510 will be received by the infrared receiver 42, and the infrared receiver 42 will transmit the signal to the external control device. The control device turns off the power supply of the magnetic block 59, and the spring 58 will reset the positioning block 56 to move outward, and the positioning block 56 will be inserted into the positioning groove 41 on the moving sleeve 4, and then the servo motor 52 will drive the moving seat 54 to move downward, and the moving seat 54 will drive the moving sleeve 4 to move downward, and the moving sleeve 4 will move downward. The sleeve 4 drives the test piece 7 to move downward, and after it moves to the position of the plastic barrel, it continues to move downward, thereby realizing a continuous pressurization test on the plastic barrel. When the plastic barrel needs to be pressurized instantaneously, first, according to the above method, the movable seat 54 is fixed on the movable sleeve 4, and then the servo motor 52 continues to work. After the test piece 7 is moved to a suitable height, the power of the magnetic block 59 is turned on, and the magnetic block 59 will adsorb the iron plate 57 on the positioning block 56. At this time, the spring 58 is in a compressed state, so that the positioning block 56 is completely moved into the active cavity 55, and will not be inserted into the positioning groove 41. In this way, under the action of gravity, the movable sleeve 4 will move downward, so that the test piece 7 hits the plastic barrel, realizing the effect of falling instantaneous pressure resistance test.

[0047] Working principle: put the plastic barrel to be tested on the test bench 1, and then the lifting hydraulic cylinder 22 drives the limit plate 23 to move upward, and the limit plate 23 drives the concave protective plate 21 to move upward, and the concave protective plate 21 blocks the plastic barrel, so that during the compression test, the crushed plastic barrel fragments will not splash to personnel, while the concave protective plate 21 moves upward, the connecting rod 24 will drive the scraper 25 to move toward the inner side of the concave protective plate 21, so that the scraper 25 moves to the position inside the concave protective plate 21, so that it does not affect the compression test of the plastic barrel, when the test is completed, the concave protective plate 21 moves downward, and the concave protective plate 21 will cause the connecting rod 24 to drive the scraper 25 to move away from the inner side of the limit plate 23, and the scraper 25 will scrape off the plastic barrel debris on the test bench 1, and clean the table of the test bench 1;

[0048] When the two pressing plates 710 are combined, a flat pressure test can be performed on the plastic barrel, such as Figure 3 As shown, when point pressure is needed, the test hydraulic cylinder 73 drives the moving bar 74 to move downward, and the moving bar 74 causes the adjusting rod 711 to drive the moving block 78 to slide on the fixed shaft 79, so that the two pressing plates 710 open the opening slot 72 at the bottom of the test seat 71, and when the moving bar 74 moves downward, it drives the test spike 75 to move downward, so that the lower end of the test spike 75 passes through the opening slot 72, so that the test spike 75 is lower than the position of the pressing plate 710, so that the test spike 75 can perform point pressure test on the plastic barrel;

[0049] When it is necessary to perform a continuous pressurization test on the plastic barrel, the servo motor 52 drives the screw 53 to rotate, and the screw 53 drives the moving seat 54 to move. When the infrared transmitter 510 on the positioning block 56 corresponds to the infrared receiver 42 inside the positioning groove 41, the signal emitted by the infrared transmitter 510 will be received by the infrared receiver 42, and the infrared receiver 42 will transmit the signal to the external control device. The control device turns off the power supply of the magnetic block 59, and the spring 58 will reset the positioning block 56 to move outward. The positioning block 56 will be inserted into the positioning groove 41 on the moving sleeve 4, and then the servo motor 52 will drive the moving seat 54 to move downward, and the moving seat 54 will drive the moving sleeve 4 to move downward, and the moving sleeve 4 will drive the test piece 7 to move downward, so that after it moves to the plastic barrel position, it continues to move downward, thereby realizing a continuous pressurization test on the plastic barrel;

[0050] When it is necessary to pressurize the plastic barrel instantaneously, first fix the movable seat 54 on the movable sleeve 4 according to the above method, then the servo motor 52 continues to work, and after the test piece 7 is moved to a suitable height, the power of the magnetic block 59 is turned on, and the magnetic block 59 will adsorb the iron plate 57 on the positioning block 56. At this time, the spring 58 is in a compressed state, so that the positioning block 56 is completely moved into the movable cavity 55 without being inserted into the positioning groove 41. In this way, under the action of gravity, the movable sleeve 4 will move downward, so that the test piece 7 hits the plastic barrel, achieving the effect of falling instantaneous pressure resistance test.
