[0005] When the utility model is in use, a straw is placed on a fixed platform, the straw is extended horizontally, the front half of the straw is located on the fixed platform, and the back half is located directly above the roller, then the fixed plate and the bending plate are driven to move downward, so that the bending plate moves downward to drive the back half of the straw to bend, and the bent straw is pushed onto the roller, thereby testing the compressive strength of the straw, and at the same time the fixed plate and the fixed platform limit the straw to prevent the front half of the straw from tilting up, thereby realizing the test of the bending of the straw.

[0006] Preferably, a groove adapted for the straw is provided on the surface of the fixing platform, and the groove extends laterally toward the bending platform and passes through the fixing platform.

[0011] This preferred solution facilitates adjustment of the distance between the magnet block and the straw by providing the magnet block and the limiting iron block, that is, adjustment of the length of the straw on the fixed platform, thereby facilitating adjustment of the bending length of the straw.

[0013] When this preferred solution is in use, a driving device drives the fixed block and the bending plate to move downward at the same time. After the fixed block hits the fixed platform, the driving device continues to move downward, and the bending plate continues to move downward. At the same time, the fixed column top is pressed against the spring, compressing the spring upward, thereby realizing the bending of the straw using the same driving device.

[0014] Preferably, the driving device includes an electric push rod.

[0015] The beneficial effects of the utility model are as follows: a straw is placed on a fixed table, the straw is extended horizontally, the front half of the straw is located on the fixed table, and the back half is located directly above the roller, and then the fixed plate and the bending plate are driven to move downward, so that the bending plate moves downward to drive the back half of the straw to bend, and the bent straw is pushed onto the roller, thereby testing the compressive strength of the straw. At the same time, the fixed plate and the fixed table limit the straw to prevent the front half of the straw from tilting up, thereby realizing the test of the bending of the straw; through the setting of the suction pipe, when the straw is placed on the fixed table, The straw is fixed in the groove by suction through the suction pipe; the distance between the magnet block and the straw is adjusted by the setting of the magnet block and the limit iron block, that is, the length of the straw on the fixed platform is adjusted, so as to adjust the bending length of the straw; a driving device drives the fixed block and the bending plate to move downward at the same time. After the fixed block reaches the fixed platform, the driving device continues to move downward, and the bending plate continues to move downward, while the top of the fixed column is fixed to the spring, and the spring is compressed upward, so that the straw can be bent using the same driving device.

[0021] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0022] Refer to the attached Figure 1-3 The utility model provides a straw bending testing device, including a frame, on which a fixing platform 1 and a bending platform are arranged in sequence along the transverse direction. The bending platform includes a plurality of rollers 2 arranged along the bending curve of the straw and connected to the frame. A bending plate 4 for driving the straw to bend is provided above the bending platform. The bottom surface of the bending plate 4 is an arc surface adapted to the bending curve of the straw. The straw bending curve is the curve formed after the second half of the straw is bent.

[0023] A groove adapted for the straw is provided on the surface of the fixed platform 1. The groove extends horizontally toward the bending platform and passes through the fixed platform 1. The fixed platform 1 is also provided with an air intake pipe 13 connected to the bottom of the groove. The air intake pipe 13 is connected to the air pump. A magnet block 12 is also provided in the groove. Several limiting iron blocks 11 are provided between the magnet block 12 and the straw.

[0024] A fixed plate 3 is provided above the fixed platform 1 to limit the tilting of the front end of the straw. A fixed block 6 is provided directly above the fixed plate 3. A sliding cavity 9 is provided in the fixed block 6. A slider slidingly connected to the sliding cavity 9 and a spring 10 above the slider are provided in the sliding cavity 9. The bottom surface of the slider is connected to a fixed column 5 that passes through the fixed block 6 and is fixed to the fixed plate 3. The fixed block 6 and the bending plate 4 are both connected to the top plate 7. A driving device 8 for driving the top plate 7 to move vertically is provided on the frame. The driving device 8 includes an electric push rod.

[0025] In particular, see the attached Figure 1 , the horizontal direction is the horizontal direction, and the vertical direction is the vertical direction.

[0026] When the utility model is in use, the straw is placed in the groove of the fixed platform 1, and the straw is extended horizontally, so that the front half of the straw is located on the fixed platform 1 and the back half is located directly above the rotating roller 2. The air pump is driven to drive the suction pipe 13 to suck air, so that the suction pipe 13 sucks the straw;

[0027] Then the driving device 8 is driven to move the fixed plate 3 and the bending plate 4 downward. After the fixed plate 3 hits the fixed platform 1, the bending plate 4 is driven downward, and the bending plate continues to move downward. At the same time, the fixed column 5 hits the spring 10, compressing the spring 10 upward, so that the fixed plate 3 hits the fixed platform 1. At the same time, the fixed plate 3 and the fixed platform 1 also play a role in preventing the front half of the straw from tilting upward;

[0028] As the bending plate 4 moves downward, the bending plate drives the second half of the straw to bend, and the bent straw is pushed onto the roller 2 to test the compressive strength of the straw, thereby achieving the test of the bending and strength of the straw.
