DETAILED DESCRIPTION

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 8 The present invention provides a technical solution: an automatic detection system for pre-packaged dairy products, including a water storage tank 1 filled with water, and further including: a vertical plate 2 fixed to the top of one side of the water storage tank 1, a fixed shaft 5 fixed to the outer wall of the vertical plate 2, and a rotating plate 6 that can rotate is installed on the fixed shaft 5.

[0032] The clamping assembly, mounted on the rotating plate 6, is used to clamp and fix the packaged products.

[0033] The first sleeve 19 is fixed to the outer wall of the rotating plate 6, and the first sleeve 19 is sleeved on the fixed shaft 5;

[0034] The second sleeve 20 is slidably mounted on the outer wall of the fixed shaft 5 via a flat key. A second spring 21 is connected between the second sleeve 20 and the vertical plate 2. The opposing surfaces of the first sleeve 19 and the second sleeve 20 are both provided with spiral inclined surfaces, and the two inclined surfaces slide against each other. When the rotating plate 6 drives the clamping assembly to be immersed in the water in the water storage tank 1, the most protruding parts of the inclined surfaces of the first sleeve 19 and the second sleeve 20 are offset from each other.

[0035] When in use, the automatic detection system for pre-packaged dairy products uses a clamping assembly to clamp and fix the packaged product to be tested. Then, an external mechanism drives the rotating plate 6 to rotate, so that the clamping assembly and the packaged product are immersed in water to achieve the purpose of testing its sealing performance.

[0036] It is worth noting that during the rotation of the rotating plate 6, the first sleeve 19 will rotate, and then, under the action of sliding and resisting on the spiral inclined plane, it will push the second sleeve 20 away from it. At the same time, the second spring 21 is compressed, accumulating elastic potential energy. For details, please refer to [link / reference needed]. Figures 7-8 Then, when the rotating plate 6 rotates and drives the clamping assembly to be immersed in the water in the water tank 1, the most protruding parts of the inclined surfaces of the first sleeve 19 and the second sleeve 20 are offset from each other. At this time, under the elastic force of the second spring 21, the second sleeve 20 and the first sleeve 19 collide. The vibration force generated by the collision shakes away the air bubbles attached to the surface of the clamping assembly and the packaged product, thereby avoiding misleading the sealing test of the packaged product and improving the accuracy of the sealing test.

[0037] Then the continued rotation of the rotating plate 6 makes the packaging product be placed underwater for a period of time to achieve the purpose of sealing detection. After the detection is completed, the rotating plate 6 turns out the clamping assembly and the packaging product from the water surface, and then the packaging product is replaced. Moreover, due to the spiral slope arrangement between the first sleeve 19 and the second sleeve 20, the rotating plate 6 will produce a knocking effect during each rotation, thereby achieving the effect of automatically eliminating the bubbles attached to the surface of the packaging product.

[0038] In one of the more preferred embodiments, the clamping assembly comprises a long slot 22 formed in the outer wall of the rotating plate 6, and a sliding block 7 is slidingly installed in the long slot 22. The outer wall of the sliding block 7 is fixed with a fixed block 8, and two curved claw pincers 9 are rotatably installed on the outer wall of the sliding block 7 on both sides of the fixed block 8. The two curved claw pincers 9 are symmetrically arranged about the vertical center line of the fixed block 8, and the outer wall of each of the two curved claw pincers 9 is fixed with a grabbing plate 10. A torsional spring is installed between each of the two curved claw pincers 9 and the sliding block 7 to make the curved claw pincers 9 rotate and open.

[0039] The clamping assembly further comprises a driving portion for driving the sliding block 7 to slide in the long slot 22, and when the sliding block 7 slides towards the fixed shaft 5, the curved portions of the two curved claw pincers 9 are in contact with and abut against the inner wall of the long slot 22 and relatively rotate.

[0040] The clamping assembly can be specifically referred to Figures 3-5 In the initial state, the driving portion makes the sliding block 7 be located at the position close to the end of the long slot 22, and the two curved claw pincers 9 are both extended out of the long slot 22 and are opened by the action of the torsional spring, thereby facilitating the placement of the packaging product to be tested between the two grabbing plates 10. Then, when the driving portion drives the sliding block 7 to move towards the fixed shaft 5, the curved portions of the two curved claw pincers 9 are in contact with and abut against the inner wall of the long slot 22, and relatively rotate under the extrusion of the long slot 22, thereby making the two grabbing plates 10 rotate to clamp and fix the packaging product. The specific process can be referred to Figures 3-5 , i.e., the state of the two grabbing plates 10 clamping.

[0041] In one of the more preferred embodiments, the driving portion comprises a fixed ring 16 fixed on the outer wall of the vertical plate 2, and the outer wall of the fixed ring 16 is provided with an adjusting sliding groove 17. The outer wall of the sliding block 7 is fixed with a pin block 18 which is inserted and slidingly installed in the adjusting sliding groove 17. The adjusting sliding groove 17 comprises a section a and a section b, and the radius of the section a gradually decreases along the rotation direction of the rotating plate 6.

[0042] The driving portion can be referred to Figure 3 and Figure 6In the initial state, the rotating plate 6 is in the vertical upward state, and at this time the two curved claw pincers 9 are also in the extended and open state, then after the packaging product is placed between the two clamping plates 10, the rotating plate 6 starts to rotate, and the pin block 18 slides along the a section of the adjusting sliding groove 17, because the radius of the a section gradually decreases, so the pin block 18 will drive the sliding block 7 to move towards the fixed shaft 5, that is, the sliding block 7 slides into the long slot 22, at this time, as known from the above, the two curved claw pincers 9 will drive the two clamping plates 10 to rotate relatively, and the clamping process is completed;

[0043] Then when the pin block 18 slides into the b section, the radius of the b section does not change, so the pin block 18 will not drive the sliding block 7 to continue to slide, so that the two clamping plates 10 remain in the clamped and fixed state, and as can be seen from the figure, at the b section, the clamping plate 10 and the packaging product are also immersed in water, at this time, the first sleeve 19 and the second sleeve 20 are impacted, and the bubbles on the surface of the first sleeve 19 and the second sleeve 20 are eliminated.

[0044] In one of the more preferred embodiments, the inner wall of the long slot 22 is rotatably installed with a limiting protruding rod 12, and the fixed block 8 is provided with a through hole for the limiting protruding rod 12 to pass through, the outer wall of the limiting protruding rod 12 is provided with a plurality of protrusions symmetrically arranged, and the end of the two curved claw pincers 9 is provided with a hook 23 arranged oppositely, and the two hooks 23 can be buckled between the protrusions on the two sides of the limiting protruding rod 12;

[0045] The adjusting sliding groove 17 further comprises a c section and a d section which are sequentially communicated with the b section, and the d section is communicated with the a section, the radius of the c section gradually decreases along the rotating direction of the rotating plate 6, the radius of the d section is greater than the maximum radius of the c section, and the connecting groove is arranged at the connection between the c section and the d section, and the first spring 11 is connected between the sliding block 7 and the inner wall of the long slot 22;

[0046] The outer wall of the fixed shaft 5 is fixedly provided with a fixed disc 14, the outer wall of the fixed disc 14 away from the center is fixedly provided with two arc-shaped rack gears 15, and the two arc-shaped rack gears 15 correspond to the a section and the c section of the adjusting sliding groove 17 respectively, and the limiting protruding rod 12 extending out of the end of the rotating plate 6 close to the fixed disc 14 is fixedly provided with a gear 13, when the gear 13 is engaged with the arc-shaped rack gear 15, the gear 13 rotates 90 degrees.

[0047] For details, please refer to Figure 3 and Figure 6 As can be known from the foregoing, when the pin block 18 slides in the b section, the elimination of the surface bubbles is completed, then with the continuous rotation of the rotating plate 6, when the pin block 18 slides to the c section, because the radius of the c section also gradually decreases, so the pin block 18 will continue to drive the sliding block 7 to continue to slide into the long slot 22, and the first spring 11 is also compressed, at this time, the hooks 23 at the ends of the two curved claw pincers 9 will contact the protrusions on the two sides of the limiting protruding rod 12, please refer to Figure 5Then when the sliding block 7 continues to move, the two hooks 23 will walk along the protrusions on both sides of the limiting convex rod 12, and in the process of walking, the hooks 23 will be continuously pushed outward, and then the bending part of the two curved claw pincers 9 will be continuously closed by the action of the torsional force of the torsional spring, so that the two clamping plates 10 continuously extrude the packaging product, and whether there is a bubble is observed by continuously extruding, so as to achieve the purpose of detecting the sealing performance thereof;

[0048] Then when the rotating plate 6 is about to rotate to the end of the c section, the gear 13 is engaged with the arc-shaped rack 15 at this time, and with the rotation of the rotating plate 6, the gear 13 also walks along the arc-shaped rack 15 and rotates, thereby driving the limiting convex rod 12 to rotate, when the pin block 18 slides to the connecting position of the c section and the d section, that is, the position of the connecting groove, at this time, the clamping plate 10 and the packaging product also separate from the water surface, and the detection is completed, at the same time, the limiting convex rod 12 also rotates to the position where the protrusions on both sides are separated from the hooks 23, at this time, under the action of the elastic force of the first spring 11, the sliding block 7 will move outwardly along the long groove 22 until the bending part of the curved claw pincers 9 is separated from the inner wall of the long groove 22, at this time, under the action of the torsional force of the torsional spring, the two clamping plates 10 are opened, the clamping action on the packaging product is released, and the packaging product is thrown out under the pushing force of the outward movement of the sliding block 7, thereby achieving the effect of automatic material removal, and improving the work efficiency;

[0049] After the material is removed, the rotating plate 6 continues to rotate, at this time, the pin block 18 slides to the d section, since the radius of the d section is greater than the maximum radius of the c section, and the d section is connected with the a section, therefore, the pin block 18 will rotate back to the a section, then continue to feed, and then continue to rotate the rotating plate 6.

[0050] In summary, the rotating plate 6 rotates one circle to eliminate the bubbles attached to the surface of the packaging product, and then detect the sealing performance thereof, thereby improving the detection accuracy.

[0051] In one of the more preferred embodiments, the vertical plate 2 is provided with a intermittent feeding hopper 3 near the outer wall of the top, and when the clamping plate 10 rotates to the lower side of the feeding hopper 3, the feeding hopper 3 is opened to feed.

[0052] For details, please refer to Figures 1-3 As can be seen from the foregoing, after the sliding block 7 slides to complete the material removal, the two clamping plates 10 are in an open state, then when it rotates to the top, the feeding hopper 3 can be opened to feed, thereby achieving the effect of automatic feeding, and further achieving the effect of automation of the whole process, greatly improving the work efficiency.

[0053] In one of the more preferred embodiments, it also includes a conveying assembly 4 for receiving materials, the conveying assembly 4 is arranged on one side of the water storage tank 1, and corresponds to the connecting position of the c section and the d section of the adjusting sliding groove 17.

[0054] The conveying assembly 4 is arranged on one side of the water storage tank 1 to receive the thrown packaging products, and the conveying assembly 4 can also adopt a conveying belt to facilitate subsequent conveying.

[0055] In one more preferred embodiment, the opposite surfaces of the two gripper plates 10 are both arc surfaces, and the surfaces of the arc surfaces are smooth. The smooth arc surfaces can help the gripper plates 10 to separate the bubbles adhered to the surfaces when the gripper plates 10 are vibrated, so as to facilitate the removal of the interference bubbles adhered from the outside, thereby reducing the probability of false measurement.

[0056] In one more preferred embodiment, the outer wall of the water storage tank 1 is made of transparent material.
