The support frame 1 is fixedly connected with the support plate 801, and the sector gear disc frame 802 is rotatably connected to the support plate 801. A torsion spring 803 is connected between the support plate 801 and the sector gear disc frame 802. The overrunning clutch 805 is fixedly connected to one side of the support frame 1. The overrunning clutch 805 is used to transmit power to the support frame 1.

A part of the movable push rod 906 is located in the corrugated slotted plate 904, and a second compression spring 907 is connected between the movable push rod 906 and the corrugated slotted plate 904. A push rod 908 is connected to one end of the movable push rod 906 away from the corrugated slotted plate 904, and the push rod 908 is slidably matched with the swing grip 807.

[0028] The chopstick compression test mechanism 10 includes an L-shaped support rod 1001, a guide frame 1002, a movable plate 1003, a pressure test frame 1004, a third compression spring 1005 and a push plate 1006. The top surface of the support frame 1 is distributedly fixed with an L-shaped support rod 1001, the top surface of the L-shaped support rod 1001 away from the guide plate 905 is fixed with a guide frame 1002, and a movable plate 1003 is in sliding contact with the guide frame 1002. A pressure test frame 1004 is connected between the movable plates 1003 on both sides. The pressure test frame 1004 is used to apply pressure to the chopsticks to make the chopsticks bend and deform, and observe whether the bent and deformed chopsticks will break, so as to judge the compression resistance of the chopsticks. A third compression spring 1005 is connected between the guide frame 1002 and the movable plate 1003, and a push plate 1006 is connected to one end of the movable plate 1003 near the fan-shaped gear disc frame 802.

[0029] The chopstick flattening mechanism 11 includes a guide sleeve 1101, a rack rod 1102, a fourth compression spring 1103, an equal-interval missing gear 1104, a connecting plate 1105, a slotted inclined plate 1106 and a pushing bar 1107. A guide sleeve 1101 is fixedly connected to one side of the support frame 1 away from the fan-shaped gear disc frame 802. The rack rod 1102 is slidably connected to the guide sleeve 1101. A fourth compression spring 1103 is connected between the guide sleeve 1101 and the rack rod 1102. The fourth compression spring 1103 passes through the rack rod 1104. 02, one end of the spline shaft 804 away from the fan-shaped gear disc frame 802 is connected to an equal-interval missing gear 1104, one end of the rack rod 1102 away from the interval missing gear 1104 is connected to a connecting plate 1105, one end of the connecting plate 1105 is connected to a slotted inclined plate 1106, and a pushing bar 1107 is fixedly connected to one side of the movable frame 2. The pushing bar 1107 and the slotted inclined plate 1106 are slidably matched to make the movable frame 2 connected to the pushing bar 1107 move relative to each other, so that the chopsticks dropped into the rubber block on the inner-toothed flat belt 7 can be placed flat.

[0030] When the newly produced family-size chopsticks need to be subjected to a compression test, the worker holds the swing handle 807 and pushes it toward the movable frame 902. The swing handle 807 swings to the position of the limit plate 808. The limit plate 808 prevents the swing handle 807 from swinging too much. The swing handle 807 drives the fan-shaped gear disc frame 802 to rotate clockwise, thereby driving the rotating gear 806 to rotate clockwise by one-third of a circle, transmitting the power to the input shaft of the overrunning clutch 805. The overrunning clutch 805 only transmits the power transmitted counterclockwise. Therefore, the output shaft of the overrunning clutch 805 will not have power transmission, the swing grip 807 swings toward the direction close to the movable frame 902, the swing grip 807 pulls the push rod 908 and the device thereon to move toward the direction close to the support frame 1, the second compression spring 907 in a normal state is compressed, and the movable push rod 906 and the corrugated slotted plate 904 are slidably matched to make the movable frame 902 reciprocate and shake left and right, so that the chopsticks in the movable frame 902 can fall onto the inner tooth flat belt 7 through the slot of the movable frame 902. Since chopsticks are placed in the inner tooth flat belt 7 just below the slot of the movable frame 902, and the inner tooth flat belt 7 does not move at this time, the chopsticks in the movable frame 902 will not fall onto the surface of the inner tooth flat belt 7 through the slot of the movable frame 902. When the push rod 908 and the device thereon move to the bottom of the guide plate 905, the movable push rod 906 pushes the push plate 1006 to move towards the support frame 1, and the movable plate 1003 drives the pressure test frame 1004 to move towards the chopsticks. The pressure test frame 1004 applies pressure to the chopsticks to make the chopsticks bend and deform, and observes whether the bent and deformed chopsticks will break, so as to judge the pressure resistance of the chopsticks. Chopsticks that have poor pressure resistance and break need to be manually picked out by workers and eliminated to prevent them from entering the market.

[0031] The worker manually pushes the swing handle 807 to reset, and the swing handle 807 swings away from the movable frame 902. The swing handle 807 pulls the push rod 908 and the device thereon to move away from the support frame 1, and the second compression spring 907 in the compressed state resets, and the movable push rod 906 no longer presses the movable plate 1003, and the pressure test frame 1004 and the chopsticks on the inner toothed flat belt 7 are no longer in contact. Through the sliding cooperation between the movable push rod 906 and the corrugated slotted plate 904, the movable frame 902 is reciprocated and shakes left and right, which makes it easier for the chopsticks to fall through the slots of the movable frame 902 and fall between the rubber blocks distributed on the inner toothed flat belt 7. When the swing handle 807 swings away from the movable frame 902, the swing handle 807 drives the fan-shaped gear disc frame 802 to rotate counterclockwise, thereby driving the rotating gear 806 to rotate counterclockwise one-third of a circle, and the rotating gear 806 transmits power to the input shaft of the overrunning clutch 805, and then the power is transmitted to the output shaft of the overrunning clutch 805 through the input shaft of the overrunning clutch 805, so that the spline shaft 804 rotates and drives the driving gear 6 and the device thereon to rotate counterclockwise, and the chopsticks that have completed the pressure test on the inner-toothed flat belt 7 move in the direction away from the pressure test frame 1004, and the chopsticks that fall through the slot of the movable frame 902 move on the inner-toothed flat belt 7 in the direction close to the pressure test frame 1004, and the counterclockwise rotation stroke of the inner-toothed flat belt 7 drives the chopsticks to move by an amount that just corresponds to the number of pressure test plates on the pressure test frame 1004. When the spline shaft 804 rotates, it drives the equal-interval gap gear 1104 to rotate counterclockwise for one-third of a turn. When the rack on the rack rod 1102 meshes with the equal-interval gap gear 1104, the equal-interval gap gear 1104 rotates for one-third of a turn to push the rack rod 1102 and the device thereon to move away from the pressure test frame 1004. The fourth compression spring 1103 is stretched, and the connecting plate 1105 drives the slotted inclined plate 1106 to slide with the push bar 1107, so that the movable frame 2 connected to the push bar 1107 makes relative movement, and the reset spring 3 is compressed. It can be known from the number of teeth on the missing gear 1104 that the equal-interval missing gear 1104 is separated from the rack on the rack rod 1102 after rotating one-third of a circle, and the stretched fourth compression spring 1103 returns to a normal state, and the rack rod 1102 and the device thereon move toward the direction close to the movable frame 902, and the reset spring 3 is reset, pushing the movable frame 2 and the device thereon to reset, and by making the movable frames 2 on both sides do reciprocating motion, the chopsticks dropped into the rubber block on the inner-toothed flat belt 7 can be placed flat, allowing the subsequent pressure test to be carried out smoothly and orderly, and the above operation is repeated until the pressure test of the chopsticks is completed.

[0032] Example 2

[0033] On the basis of Example 1, Figure 7As shown, a guide strip 12 is also included. One end of the L-shaped support rod 1001 away from the support frame 1 is connected to the guide strip 12. The guide strip 12 is used to keep the chopsticks in the same horizontal plane.

[0034] The symmetrically installed guide strips 12 guide the chopsticks when they move toward the pressure test frame 1004, so that the chopsticks are on the same horizontal plane.
