[0002] As a common packaging container, paper cups are widely used in catering, food, beverages and other fields. Therefore, the quality of paper cups has an important impact on food safety and consumer health. In the production process of paper cups, it is necessary to test its size, capacity, cup body stiffness, cup bottom strength and leakage to ensure that the quality of paper cups meets the requirements. Among them, cup body stiffness is one of the important safety performance parameters of paper cup quality. It refers to the degree of deformation of the cup body under the action of force. If the cup body of the paper cup is not stiff enough, it will lead to problems such as unstable placement and easy deformation, and even affect the safety of use. Therefore, the cup body stiffness test of paper cups is one of the important links in paper cup quality inspection.

[0003] In the related art, a Chinese patent with publication number CN211825481U proposes a paper cup compression test device, which includes a placement plate for paper cups, two sets of lifting rods vertically arranged on the placement plate, a pressure plate and a receiving plate slidably sleeved on the two sets of lifting rods at both ends, locking parts are arranged between the two ends of the receiving plate and the lifting rods, and a through hole is opened on the receiving plate for the paper cup to pass through. The pressure plate is provided with an annular cylinder perpendicular to the pressure plate, the top of the annular cylinder is open, and a weight for pressing down the paper cup is placed in the annular cylinder. Through the above scheme, a safer and faster compression test of paper cups is achieved.

[0004] The above-mentioned related technologies have the following defects: when testing the stiffness of paper cups, there may be inaccurate positioning problems during the placement and lifting of the paper cups. If the paper cups are not placed in the center or are eccentric, the pressure on the paper cups during the test will not be centered, which will directly affect the accuracy of the test results.

[0019] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0020] The present application embodiment discloses a paper cup quality detection device for paper cup production. Figure 1 and Figure 2 A paper cup quality inspection device for paper cup production includes a machine 1, a cross bar 2 is mounted on the machine 1, and two lifting rods 3 fixed to the machine 1 are vertically fixed at the lower edges of both ends of the cross bar 2, a hook 21 for hanging a weight 22 is fixed to the middle of the cross bar 2, and a platform 4 for placing paper cups is provided directly below the hook 21. The platform 4 is lifted and set on the machine 1, and a plurality of centering rods 6 are hinged on the peripheral side of the upper end surface of the platform 4. At least three groups of centering rods 6 are provided, and the centering rods 6 are arranged in an arc shape and the inner arc side thereof is close to the center of the platform 4. The platform 4 is also provided with a centering mechanism for driving the plurality of centering rods 6 to turn over synchronously. A lifting rod is connected between the lower end surface of the platform 4 and the machine 1, and the lifting rod is composed of a plurality of circular tubes with decreasing or increasing diameters in sequence, and a sealing ring is also provided at the joint of two adjacent circular tubes to form a sliding damping effect.

[0021] With such arrangement, when the paper cup is subjected to a compression test, the weight 22 is first hung on the hook 21 on the crossbar 2, and the paper cup is placed on the platform 4. Then, the centering mechanism is used to drive multiple centering rods 6 to rotate simultaneously and approach the centering rod 6 to center the paper cup. After the centering is completed, the centering mechanism is used to drive multiple centering rods 6 on the platform 4 to rotate away from each other to prevent the peripheral side of the paper cup from receiving the pushing effect of the centering rod 6 during the compression test and affecting the test result. Then, the platform 4 is pushed to move up slowly until the paper cup is obviously deformed after supporting the weight 22, and the load-bearing test is completed. In addition, the arc surface of the centering rod 6 can increase the contact area with the paper cup, thereby ensuring the non-destructive centering effect of the centering rod 6 on the paper cup, thereby improving the accuracy of the paper cup test result.

[0022] Specifically, refer to Figure 1 and Figure 2The centering mechanism includes an outer ring 5 coaxially arranged with the platform 4, and a shift block 51 is fixedly connected to the outer ring 5. The side of the centering rod 6 away from the middle of the platform 4 is hinged to the outer ring 5. The centering rod 6 is provided with a long groove 61 arranged along its length direction. A fixed shaft 41 penetrating the long groove 61 is fixedly connected to the platform 4, and the centering rod 6 is hinged to the platform 4 through the fixed shaft 41.

[0023] And, refer to Figure 2 A reset structure 7 is provided on the platform 4 for driving the outer ring 5 to reset after rotation. The reset structure 7 is configured as a tension spring connected between the outer ring 5 and the platform 4; and a buffer 62 is installed on the side of the centering rod 6 close to the middle of the platform 4, and the buffer 62 is configured as a sponge block.

[0024] After such arrangement, the centering rod 6 coaxially hinged on the outer ring 5 can be synchronously flipped and rotated on the outer ring 5, and the long groove 61 can adjust the centering effect according to the size of the paper cup. The long groove 61 is fixed by the fixed shaft 41 to ensure the stability and accuracy of the paper cup during the lifting and lowering process of the platform 4 after the paper cup is centered. After the paper cup test is completed, the paper cup is taken out, and the reset structure 7 set on the outer ring 5 of the platform 4 can generate an opposite elastic force to help the centering rod 6 return to its original position; the sponge buffer 62 in the middle of the centering rod 6 can effectively buffer the pressure generated by the paper cup during centering to prevent the paper cup from breaking or deforming.

[0025] At the same time, refer to Figure 1 A force balancing plate 8 is also provided between the crossbar 2 and the platform 4, and both ends of the force balancing plate 8 are respectively sleeved on the two lifting rods 3. After such a setting, the force balancing plate 8 is placed between the paper cup to be tested and the weight 22, and the platform 4 is lifted, so that the paper cup lifts the weight 22 through the force balancing plate 8. The force balancing plate 8 can balance the weight of the weight 22 and disperse the downward pressure of the weight 22, so as to avoid excessive concentration of pressure and damage to the paper cup.

[0026] And, refer to Figure 1 A limit block 31 located below the force equalizing plate 8 is fixedly connected to the lifting rod 3, and the distance between the limit block 31 and the platform 4 is greater than the height of the paper cup to be tested; a rough structure is provided on the side of the force equalizing plate 8 close to the platform 4, and the rough structure is arranged opposite to the platform 4, and the rough structure can be a frosted surface or a rubber sheet.

[0027] After such arrangement, the limit block 31 on the lifting rod 3 prevents the force equalizing plate 8 from sliding downward, so as to improve the convenience of installing the paper cup. At the same time, the rough structure on the force equalizing plate 8 can reduce the possibility of the paper cup moving sideways after being pressed, thereby further ensuring that the axial pressure is applied to the paper cup during the test, so as to improve the accuracy of the test result.

[0028] The implementation principle of a paper cup quality detection device for paper cup production in the embodiment of the present application is as follows:

[0029] When performing a compression test on a paper cup, first hang the weight 22 on the hook 21 on the crossbar 2, place the paper cup on the platform 4, and then drive the multiple centering rods 6 to rotate simultaneously and approach the centering rod 6 through the centering mechanism to center the paper cup; after the centering is completed, the multiple centering rods 6 on the platform 4 are driven to rotate away from each other through the centering mechanism at the same time, so as to prevent the peripheral side of the paper cup from receiving the pushing effect of the centering rod 6 during the compression test and affecting the test result; and the arc surface of the centering rod 6 can increase the contact area with the paper cup, thereby ensuring the non-destructive centering effect of the centering rod 6 on the paper cup, thereby improving the accuracy of the paper cup test result.
