[0037] Example 1

[0038] This embodiment provides a blocking structure such as Figure 1-4 As shown, the blocking structure includes a driving unit 1, a rotating shaft 2, a baffle 3 and a first limiting unit 4. The output shaft of the driving unit 1 is connected to the input end of the rotating shaft 2 through the first limiting unit 4, so that the rotating shaft 2 can rotate synchronously with the output shaft of the driving unit 1, and the output end of the rotating shaft 2 is connected to the baffle 3 to drive the baffle 3 to rotate.

[0039] Specifically, in this embodiment, the drive unit 1 is used to provide power; the rotating shaft 2 is used to realize the transmission of power; the first limiting unit 4 is used to realize the connection and cooperation between the drive unit 1 and the rotating shaft 2; the baffle 3 can rotate to prevent materials from falling; for example, the blocking structure provided in the plate embodiment should be on the conveying device, which is arranged on the side of the conveying device, and the baffle 3 is rotated to a suitable position according to the actual situation to block the materials on the conveying device to prevent the materials from falling.

[0040] First, the blocking structure provided in this embodiment eliminates the reducer, thereby improving the transmission efficiency of the mechanism; in addition, the drive unit and the rotating shaft are limited by the first limiting unit, and no coupling connection is required, thereby eliminating the work of coupling assembly and maintenance. During the operation of the blocking structure, the drive unit, under the action of the first limiting unit, causes the rotating shaft to rotate synchronously, and the rotating shaft drives the blocking plate to rotate, and the blocking plate plays the role of blocking the material. The blocking structure provided in this embodiment is compact, has few parts, occupies little space, and has high reliability.

[0041] In a specific embodiment, the first limiting unit 4 includes a flat position 41 opened on the output shaft of the driving unit 1, and a cylindrical pin 42 inserted along the input end of the rotating shaft 2; after the output shaft of the driving unit 1 is matched with the center hole of the rotating shaft 2, the flat position 41 can be tangent to the cylindrical pin 42.

[0042] Specifically, Figure 3 and Figure 4 As shown, the flattened portion 41 is a plane formed on the output shaft of the drive unit 1 , that is, a portion of the output shaft of the drive unit 1 is cut off in the axial direction so that a portion of the surface of the output shaft of the drive unit 1 is a flat structure.

[0043] In order to achieve the cooperation between the rotating shaft 2 and the output shaft of the driving unit 1, the rotating shaft 2 is provided with a center hole, and the output shaft of the driving unit 1 can be inserted into the center hole; and in order to avoid relative rotation between the rotating shaft and the output shaft of the driving unit 1, a cylindrical pin 42 is inserted above the center hole in the axial direction of the rotating shaft 2, and the cylindrical pin 42 just contacts the flat part 41. At this time, the flat part 41 cooperates with the circular surface of the cylindrical pin 42 to avoid relative rotation between the two, so that the driving unit 1 can drive the rotating shaft 2 to rotate synchronously.

[0044] In addition, the first limiting unit 4 can also be other specific structures, for example: the rotating shaft 2 is connected to the output shaft of the driving unit 1 through a flat key, or the rotating shaft 2 is connected to the output shaft of the driving unit 1 through a fastening bolt, or the rotating shaft 2 is connected to the output shaft of the driving unit 1 through a top screw.

[0045] In a specific embodiment, the drive unit 1 includes a stepper drive and control integrated machine 11, a mounting seat 12, a bearing 13 and a sleeve 14. The stepper drive and control integrated machine 11 and the mounting seat 12 are fixedly connected. The mounting seat 12 has a hole 121. The bearing 13 is arranged in the hole 121. The sleeve 14 is arranged on the outer end surface of the bearing 13; the stepper drive and control integrated machine 11 passes through the sleeve 14 and the bearing 13 in sequence.

[0046] The stepper drive control integrated machine 11 integrates the motor body and the driver, and this arrangement facilitates wiring. The mounting seat 12 has two fixing surfaces arranged perpendicular to each other, so that the blocking structure can be installed in different directions; for example, in the horizontal direction or in the vertical direction. The mounting seat 12 is formed by sheet metal welding.

[0047] In addition, the opening formed between the above-mentioned fixing surfaces faces outward, and this arrangement makes the blocking structure easy to maintain; the mounting seat 12 is made by integral processing to ensure batch consistency.

[0048] In addition, the mounting seat 12 has a hole 121 , the bearing 13 is mounted in the hole 121 , the sleeve 14 is mounted on the outer end surface of the bearing 13 , and the end surface of the stepper drive control integrated machine 11 is in surface contact with the sleeve 14 to press the bearing 13 .

[0049] In a specific embodiment, the blocking structure further includes a second limiting unit 5 , which is disposed on the rotating shaft 2 to limit the axial movement of the rotating shaft 2 .

[0050] The second limiting unit 5 is mainly used to prevent the rotating shaft 2 from moving in the axial direction.

[0051] In a specific embodiment, the second limiting unit 5 is a clamping ring clamped on the rotating shaft 2 .

[0052] More specifically, a groove may be provided on the outer surface of the rotating shaft 2, and a retaining ring may be sleeved on the groove and further fixedly connected to the output shaft of the driving unit 1 inside the rotating shaft 2, thereby achieving a fixed connection between the rotating shaft 2 and the output shaft of the driving unit 1 and playing an axial limiting role.

[0053] In a specific embodiment, the blocking structure also includes a sensing unit 6, the moving end of the sensing unit 6 is arranged on the rotating shaft 2, and the fixed end of the sensing unit 6 is arranged on the mounting seat 12; the moving end rotates with the rotating shaft 2 to determine the position of the blocking piece 3 through the rotating shaft 2, and feed back the position to the fixed end.

[0054] In a specific embodiment, the sensing unit 6 includes a sensor 61 and a sensing sheet 62 . The sensing sheet 62 is fixedly connected to the rotating shaft 2 , and the sensor 61 is fixed on the mounting seat 12 .

[0055] Of course, in a specific embodiment, the blocking structure further includes a controller, and the controller can control the rotation angle of the blocking piece 3 through the driving unit 1 by receiving data collected by the sensing unit 6 .

[0056] More specifically, the sensing sheet 62 is fixedly connected to the rotating shaft 2 , and the sensor 61 can sense the position of the sensing sheet 62 , determine the rotation angle of the rotating shaft 2 through the position of the sensing sheet 62 , and further determine the position of the blocking sheet 3 at this time.

[0057] In a specific embodiment, two sensors 61 are provided, and the two sensors 61 are fixed on the mounting base 12 at an angle of 180°.

[0058] For better explanation, it is assumed that the two sensors 61 are the first sensor and the second sensor, the first sensor is arranged at the top of the mounting base 12, and the second sensor is arranged at the bottom of the mounting base 12. It is assumed that when the first sensor can sense the sensing sheet 62 and the second sensor cannot sense the sensing sheet 62, the baffle 3 is in the first position, and when the first sensor cannot sense the sensing sheet 62 and the second sensor can sense the sensing sheet 62, the baffle 3 is in the second position. The first position and the second position correspond to the start and stop of the drive unit 1, respectively. This setting method realizes the automation of the blocking structure. For example: when the stepper drive and control integrated machine 11 drives the rotating shaft 2 to rotate, when the sensing sheet 62 on the rotating shaft 2 triggers the first sensor, the stepper drive and control integrated machine 11 will stop working, and when the sensing sheet 62 triggers the second sensor, the stepper drive and control integrated machine 11 will start working.

[0059] Of course, the sensing unit 6 may also be other structures, such as a micro switch or a proximity switch.

[0060] The blocking structure provided in this embodiment has a mounting seat 12 fixedly connected to the stepper drive and control integrated machine 11, the output shaft of the stepper drive and control integrated machine is connected to the rotating shaft 2 through a shaft hole, the output shaft of the stepper drive and control integrated machine 11 is limited by installing a cylindrical pin 42 on the rotating shaft 2, the flat position 41 on the shaft of the stepper drive and control integrated machine 11 is tangentially limited to the cylindrical pin 42 surface, so that the rotating shaft 2 can rotate with the output shaft of the stepper drive and control integrated machine 11, and the rotating shaft 2 is connected to the bearing 13 at the same time, the bearing 13 is installed in the hole 121, and the shaft sleeve 14 is installed on the outer end surface of the bearing 13, the end surface of the stepper drive and control integrated machine 11 is in contact with the shaft sleeve 14 to press the bearing 13, the retaining ring is connected to the rotating shaft 2 to play a limiting role, the sensor sheet 62 is fixedly connected to the rotating shaft 2, the two sensors 61 are connected to the mounting seat 12, and the blocking sheet 3 is fixedly connected to the rotating shaft 2 by fixing bolts 7.

[0061] The stepper drive and control integrated machine 11 adopted in this embodiment integrates the driver and the motor body for convenient wiring. The mechanism eliminates the reducer, thereby improving the transmission efficiency of the mechanism. The output shaft of the stepper drive and control integrated machine 11 is limited by the cylindrical pin 42 and the flat position 41, and does not require a coupling connection, thereby eliminating the work of coupling assembly and maintenance. The baffle 3 serves to block the material. The mounting seat 12 has two fixed surfaces, so that the mechanism can be installed horizontally or vertically. The structural opening of the mounting seat 12 is designed to face outward, which is convenient for assembly and maintenance. The blocking mechanism provided in this embodiment is more compact, more consistent, smaller in size, and more stable and reliable in performance than the existing blocking mechanism.
