Description

Technical Field

[0001] This invention relates to the field of servo motor technology, and in particular to a servo motor for an unmanned packaging machine. Background Technology

[0002] Servo motors can control speed and position with extremely high accuracy. They convert voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, they are used as actuators and have characteristics such as a small electromechanical time constant and high linearity. They can convert received electrical signals into angular displacement or angular velocity output on the motor shaft. Servo motors are divided into two main categories: DC and AC servo motors. Their main characteristic is that they do not rotate when the signal voltage is zero, and their speed decreases uniformly as the torque increases.

[0003] Servo motors offer precise positioning, making them widely used in various fields. Currently, unmanned packaging machines complete the entire process from automatic unpacking → automatic packing → automatic weighing → inkjet coding → automatic I-shaped sealing → automatic four-corner sealing → automatic cross-shaped strapping → palletizing system → automatic pallet packaging → automatic horizontal strapping → automatic online wrapping. Most of the drive mechanisms utilize servo motors.

[0004] However, the mounting base of existing servo motors is fixed. If the mounting point cannot match the mounting base, it needs to be installed through a custom connecting flange, which is troublesome and time-consuming. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a servo motor for an unmanned packaging machine, which solves the problem that the mounting base of the existing servo motor is fixed, and if the mounting point cannot match the mounting base, it needs to be installed through a customized connecting flange, which is troublesome and time-consuming.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A servo motor for an unmanned packaging machine includes a motor body and a mounting mechanism. The mounting mechanism includes two identical fixing components, which are symmetrically arranged on both sides of the motor body. Each fixing component includes a fixing plate and a connecting plate. The fixing plate and the connecting plate are rotatably connected. The fixing plate is provided with fixing ears. A connecting component is provided between the connecting plate and the motor body. The connecting component includes a connecting strip, one end of which is hinged to the motor body and the other end of which is hinged to the connecting plate.

[0008] Furthermore, a limiting component is provided on the fixed plate. The limiting component includes a limiting plate and a limiting rod. The limiting rod is fixedly connected to the limiting plate and passes through the fixed plate and the connecting strip in sequence to be inserted into the motor body.

[0009] Furthermore, the fixing plate has stepped holes, the bottom of the connecting plate has stepped grooves, and the connecting plate is inserted into the stepped holes.

[0010] Furthermore, a first hinge joint is provided at the bottom of the connecting plate, and a hinge groove is provided at one end of the connecting strip, with the first hinge joint hinged in the hinge groove.

[0011] Furthermore, the motor body has a first mounting groove at the position corresponding to the fixing component, a second mounting groove is provided on one side of the first mounting groove, a hinge seat is provided at the connection between the first mounting groove and the second mounting groove, and a second hinge joint is provided at the end of the connecting strip away from the connecting plate, and the second hinge joint is hinged to the hinge seat.

[0012] Furthermore, the fixing plate is provided with an installation cylinder, the limiting plate is slidably disposed in the installation cylinder, the top of the installation cylinder is provided with a limiting ring, the limiting ring is provided with a threaded hole, a bolt is threadedly connected in the threaded hole, the bottom of the bolt abuts against the limiting plate, the bottom of the limiting plate is provided with an elastic element, one end of the elastic element is connected to the limiting plate, and the other end is connected to the fixing plate.

[0013] Furthermore, an adjusting cap is provided at the outer end of the bolt, and several anti-slip protrusions are provided on the outer circumference of the adjusting cap.

[0014] The beneficial effects of this invention are:

[0015] 1. By setting a fixing plate, connecting plate, and connecting strip, and rotating the connecting plate and connecting strip, the fixing ears on the fixing plate can face multiple mounting surfaces of the motor body, so that the motor body can be used for different mounting points. This avoids the situation where the mounting point cannot match the fixing ears, and there is no need to customize the connecting flange separately. It is simple, quick, and saves time.

[0016] 2. By setting a limiting component and screwing in the bolt, the limiting plate and limiting rod can be adjusted to limit and fix the fixing plate and connecting strip; when the bolt is unscrewed, the spring causes the limiting plate and limiting rod to spring up, thus eliminating the limitation and fixation of the fixing plate and connecting strip.

Detailed Implementation

[0022] 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.

[0023] like Figures 1-4 As shown, a servo motor for an unmanned packaging machine according to the present invention includes a motor body 1 and a mounting mechanism. In this embodiment, the motor body 1 is a servo motor for an unmanned packaging machine using existing technology. The mounting mechanism includes two identical fixing components symmetrically arranged on both sides of the motor body 1. Each fixing component includes a fixing plate 2 and a connecting plate 3. The fixing plate 2 and the connecting plate 3 are rotatably connected. The fixing plate 2 is provided with fixing ears 21, which are used to fix the motor body 1 at the mounting point. A stepped hole 22 is provided on the fixing plate 2, and a stepped groove 31 is provided at the bottom of the connecting plate 3. The connecting plate 3 is inserted into the stepped hole 22, so that the connecting plate 3 is rotatably connected to the fixing plate 2. For ease of understanding of this embodiment, as shown... Figure 4 As shown, the fixing surfaces of the motor body 1 include surface A, surface B, surface C, surface D, and surface E. At this time, the two sets of fixing components are located on surface B and surface C respectively, and the fixing ears 21 of the two fixing plates 2 face surface A. This allows for the fixing of the upper and lower sides of surface A of the motor body 1. Furthermore, by rotating the fixing plates 2 so that the fixing ears 21 of the two fixing plates 2 face surface D or surface E, the motor body 1 can be fixed to surface D or surface E.

[0024] A connecting assembly is provided between the connecting plate 3 and the motor body 1. The connecting assembly includes a connecting strip 4, one end of which is hinged to the motor body 1, and the other end of which is hinged to the connecting plate 3. A first hinge joint 32 is provided at the bottom of the connecting plate 3. A hinge groove 41 is provided at one end of the connecting strip 4, and the first hinge joint 32 is hinged within the hinge groove 41, thereby achieving the hinge connection between the connecting strip 4 and the connecting plate 3 and fixing the connecting plate 3 within the stepped hole 22. This prevents the connecting plate 3 from moving arbitrarily.

[0025] A first mounting groove 11 is provided on the motor body 1 at the position corresponding to the fixing component. A second mounting groove 12 is provided on one side of the first mounting groove 11. A hinge seat 13 is provided at the connection between the first mounting groove 11 and the second mounting groove 12. A second hinge joint 42 is provided at the end of the connecting strip 4 away from the connecting plate 3. The second hinge joint 42 is hinged to the hinge seat 13. This achieves the hinge connection between the connecting strip 4 and the motor body 1. By providing the first mounting groove 11 and the second mounting groove 12, the connecting strip 4 can be embedded in the first mounting groove 11 and the second mounting groove 12, preventing the connecting strip 4 from protruding outside the motor body 1, ensuring that the exterior of the motor body 1 is flat, and avoiding affecting the installation of the motor body 1.

[0026] By rotating the connecting strip 4 in the first mounting slot 11 into the second mounting slot 12, and causing the fixing components to rotate together, the two sets of fixing components are positioned on surfaces D and E respectively. Figure 4 As shown, the fixing ears 21 of the two fixing plates 2 face side A. At this time, the left and right sides of side A of the motor body 1 can be fixed. Furthermore, by rotating the fixing plates 2, the fixing ears 21 of the two fixing plates 2 can face side B or side C, thereby fixing side B or side C of the motor body 1. This allows for fixing to the upper and lower sides of side A, the left and right sides of side A, side B, side C, side D, and side E of the motor body 1, fully adapting to the location of the installation point. No separate connecting flange is required, making it simple, quick, and time-saving.

[0027] A limiting component is provided on the fixed plate 2 to limit the movement of the fixed plate 2 and the connecting strip 4, preventing them from moving freely. The limiting component includes a limiting plate 51 and a limiting rod 52. The limiting rod 52 is integrally formed with the limiting plate 51 and passes through the fixed plate 2 and the connecting strip 4 in sequence before being inserted into the motor body 1, thus limiting the movement of the fixed plate 2 and the connecting strip 4. In this embodiment, multiple limiting rods 52 are provided, all of which pass through the fixed plate 2 and are inserted into the motor body 1 to ensure the limiting effect on the fixed plate 2 and prevent it from loosening.

[0028] A mounting cylinder 23 is provided on the fixed plate 2. The limiting plate 51 is slidably disposed within the mounting cylinder 23. A limiting ring 24 is provided at the top of the mounting cylinder 23 to prevent the limiting plate 51 from sliding out of the mounting cylinder 23. A threaded hole 241 is provided on the limiting ring 241, and a bolt 6 is threaded into the threaded hole 241. The bottom of the bolt 6 abuts against the limiting plate 51. Rotating the bolt 6 can push the limiting plate 51 downward, so that the limiting rod 52 at the bottom of the limiting plate 51 is firmly inserted into the motor body 1. An elastic element 7 is provided at the bottom of the limiting plate 51. One end of the elastic element 7 is connected to the limiting plate 51, and the other end is connected to the fixed plate 2. In this embodiment, the elastic element 7 is preferably a spring. The spring is normally in a compressed state. When the bolt 6 is screwed upward, the spring pushes the limiting plate 51 upward, so that the limiting plate 51 moves the limiting rod 52 upward, thereby releasing the limitation on the fixed plate 2 and the connecting strip 4, so that the fixing assembly can be adjusted.

[0029] An adjusting cap 61 is provided at the outer end of the bolt 6. Several anti-slip protrusions 611 are provided on the outer circumference of the adjusting cap 61. By providing the adjusting cap 61 and the anti-slip protrusions 611, it is easy to rotate the bolt 6.

[0030] When using the servo motor for the unmanned packaging machine of the present invention, the position of the fixing component is adjusted according to the actual position of the installation point, so that the fixing ears 21 on the fixing plate 2 correspond to the position of the installation point; under normal conditions, the two sets of fixing components are located on the B side and the C side respectively, and the fixing ears 21 of the two fixing plates 2 face the A side, so that the left and right sides of the A side of the motor body 1 can be fixed.

[0031] If it is necessary to fix the D side of the motor body 1, unscrew the bolt 6 upwards, and the spring pushes the limiting plate 51 upwards, causing the limiting plate 51 to move the limiting rod 52 upwards, releasing the limitation on the fixing plate 2 and the connecting strip 4. Then, rotate the two fixing plates 2 so that the fixing ears 21 of the two fixing plates 2 face the D side. Finally, screw in the bolt 6 and push the limiting plate 51 downwards so that the limiting rod 52 at the bottom of the limiting plate 51 is firmly inserted into the motor body 1 for fixation. Similarly, rotate the two fixing plates 2 so that the fixing ears 21 of the two fixing plates 2 face the E side to fix the E side of the motor body 1.

[0032] If it is necessary to fix the left and right sides of the A side of the motor body 1, unscrew the bolt 6, rotate the connecting strip 4 in the first mounting groove 11 to the second mounting groove 12, and drive the fixing components to rotate together, so that the two sets of fixing components are located on the D side and the E side respectively, and the fixing ears 21 of the two fixing plates 2 face the A side, so that the left and right sides of the A side of the motor body 1 can be fixed.

[0033] If it is necessary to fix the B side of the motor body 1, rotate the two fixing plates 2 so that the fixing ears 21 of the two fixing plates 2 face the B side; similarly, rotate the two fixing plates 2 so that the fixing ears 21 of the two fixing plates 2 face the C side, and the C side of the motor body 1 can be fixed.
