Description

TECHNICAL FIELD

[0002] When the output shaft of the embroidery machine spindle motor is connected with a belt pulley and force is transmitted through a transmission belt, the distal end of the output shaft is suspended. In this case, when the motor is in a high-speed running state, the tension of the transmission belt will exert a bending moment on the output shaft, causing bending stress on the output shaft. Since the distal end is not additionally supported, this unilateral force makes the output shaft more prone to deformation or fatigue damage. As the rotational speed increases, the centrifugal force also increases, further exacerbating these effects and increasing the risk of deformation or even breakage of the output shaft. SUMMARY

[0027] Embodiments of the present disclosure will be described in more detail with reference to the drawings. While certain embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be interpreted as being limited to the embodiments set forth herein, but rather, these embodiments are provided so that the present disclosure can be more thoroughly and completely understood. It is understood that the drawings and embodiments of the present disclosure are for exemplary purposes only and are not intended to limit the scope of protection of the present disclosure.

[0028] In the description of embodiments of the present disclosure, the term "comprising" and its conjugates should be open-ended, i.e., "including, but not limited to". The term "based on" should be understood as "based at least on". The term "one embodiment" or "an embodiment" should be understood as "at least one embodiment". The terms "a first", "a second", etc. can refer to different or the same objects. Other explicit or implicit definitions can also be included below.

[0029] As mentioned before, when the output shaft of the embroidery machine main shaft motor is connected to a pulley and force is transmitted through a transmission belt, the distal end of the output shaft is suspended. In this case, when the motor is in a high-speed running state, the tension of the transmission belt will exert a bending moment on the output shaft, causing bending stress on the output shaft. Since the distal end is not additionally supported, this unilateral force makes the output shaft more prone to deformation or fatigue damage. Deformation of the output shaft can cause misalignment or sliding of the pulley, which in turn affects the tension and position of the transmission belt, ultimately affecting the accuracy and quality of the pattern. When the output shaft breaks, the embroidery machine needs to be stopped for repair, affecting production progress and efficiency.

[0030] To this end, the present embodiment provides an adjustable motor mount capable of supporting the distal end of the motor output shaft, reducing the bending and deformation of the main shaft motor output shaft during assembly and use of the embroidery machine, and reducing the failure rate of the embroidery machine and improving the stability of the embroidery machine. The principle of the adjustable motor mount according to the present embodiment will be described in detail below with reference to the drawings.

[0031] Figure 1A perspective view of an adjustable motor base according to an embodiment of the present disclosure is shown. As Figure 1 The adjustable motor base 10 includes a first mount 100 and a second mount 200. The first mount 100 is used to realize the installation of the motor base 10 on the embroidery machine. The second mount 200 is used to fix the main shaft motor 20 of the embroidery machine. A pulley 30 can be installed on the output shaft of the motor. The pulley 30 is connected to the main shaft of the embroidery machine through a transmission belt (not shown in the figure) to realize the driving of the main shaft of the embroidery machine by the motor 20. The second mount 200 can be connected and fixed with the motor 20 to realize the synchronous movement of the motor and the second mount. At the same time, the second mount 200 can adjust the position of the motor 20 relative to the first mount 100 by moving relative to the first mount 100, so as to tension the transmission belt installed on the pulley 30. Figure 2 A perspective view of the second mount according to an embodiment of the present disclosure is shown. As Figure 2 As shown, the second mount can include a motor fixing portion 210 for fixing the motor 20, a shaft supporting portion 220 for supporting the output shaft of the motor, and a transmission belt passing portion 230 for the transmission belt installed on the pulley 30 of the output shaft to pass through. The shaft supporting portion 220 is arranged in the axial direction of the output shaft of the motor and is spaced apart from the motor fixing portion 210, so that the pulley 30 installed on the output shaft is located between the shaft supporting portion 220 and the motor fixing portion 210, and the transmission belt passing portion 230 is also located between the motor fixing portion 210 and the shaft supporting portion 220 and is directed to the exit position of the belt on the pulley 30 of the output shaft.

[0032] In this way, by arranging the shaft supporting portion supporting the output shaft on the second mount, when the motor is installed on the second mount, the part of the output shaft close to the motor body is supported by the motor body, and the part relatively far away from the motor body is supported by the shaft supporting portion. When the pulley is connected and installed on the output shaft, the part of the output shaft on which the pulley is installed is just located between the motor fixing portion and the shaft supporting portion, so that the shaft section on which the pulley is installed on the output shaft is supported by the motor body and the shaft supporting portion at both ends. Therefore, during the subsequent movement of the second mount along the radial direction of the output shaft to adjust the position of the pulley on the motor to tension the transmission belt, the tension at the position of the pulley is evenly distributed to the output shaft on both sides of the pulley, avoiding the deformation of the output shaft due to the unilateral force when the pulley is tensioned. During the operation of the embroidery machine after the transmission belt is tensioned, the motor fixing portion and the shaft supporting portion of the second mount will continue to support the output shaft on both sides of the pulley, avoiding the deformation and fracture of the output shaft during the operation of the embroidery machine. Therefore, the failure rate of the embroidery machine can be reduced, and the stability of the embroidery machine can be improved.

[0033] The second mount can adopt any structure capable of mounting the motor. By mounting the motor to the second mount, the second mount can be moved synchronously with the motor, so as to adjust the position of the motor to tighten the transmission belt mounted to the motor through the pulley. Figure 3 A perspective view of the second mount according to an embodiment of the present disclosure is shown. As shown in the figure, the second mount can include a first mount 110 and a second mount 120. The first mount 110 can be mounted to the second mount 120 through a plurality of bolts 130. The first mount 110 can be mounted to the second mount 120 through the plurality of bolts 130, so as to be moved synchronously with the second mount 120. Figure 3As shown, the motor fixing part 210 can be a plate body for fixedly connecting with the main body of the motor. A through hole is provided in the plate body at a position corresponding to the motor output shaft 21. The end face of the main body of the motor for extending the output shaft is fixedly attached to one side face of the plate body. The output shaft passes through the through hole and extends to the other side face of the plate body. The shaft support part 220 is provided outside the other side face. In one or more embodiments of the present disclosure, the shaft support part 220 can include a bearing 221 capable of supporting the rotating shaft without affecting the rotation of the rotating shaft, including but not limited to a rolling bearing, a sliding bearing, a magnetic levitation bearing, an air shaft, and a composite bearing, etc. In one or more embodiments of the present disclosure, the bearing 221 can be installed by applying pressure, bolt fixing, or adhesive, etc. In one or more embodiments of the present disclosure, the shaft support part 220 further includes a bearing seat 220 for assisting the installation of the bearing 221. The bearing seat can provide a stable support base for the bearing, ensuring that the bearing maintains the correct axial and radial position during operation, thereby providing more stable support for the output shaft. In one or more embodiments of the present disclosure, the bearing can be provided with a bearing sleeve for cooperating with the motor output shaft to reduce wear and noise and improve the wear resistance of the bearing. In one or more embodiments of the present disclosure, there is a certain gap between the motor fixing part 210 and the shaft support part 220, so that the pulley 30 can be installed on the shaft segment of the output shaft between the shaft support part 220 and the motor fixing part 210. When adjusting the position of the motor to tension the drive belt, the motor fixing part, the motor, and the shaft support part will move as a whole with the second mounting seat. There is no relative displacement between the motor and the motor fixing part and the shaft support part. The shaft segments on both sides of the pulley installation position on the output shaft can be continuously and stably supported during the tensioning adjustment, reducing the risk of deformation. In order to facilitate the transmission belt installed on the pulley 30 to be connected in transmission with the embroidery machine spindle, in one or more embodiments of the present disclosure, a transmission belt passing part 230 is provided at the gap position between the motor fixing part 210 and the shaft support part 220. The transmission belt passing part 230 can be one or more spaces for the transmission belt to pass through. One end of the transmission belt can be sleeved on the pulley 30, and the other end of the transmission belt can be led out through the one or more spaces and installed on another pulley. When the second mounting seat 200 moves relative to the first mounting seat 100, the motor 20 will move with the second mounting seat 200. By moving the position of the second mounting seat, the distance between the pulley 30 installed on the motor output shaft and the other end pulley of the transmission belt can be adjusted, thereby tensioning the transmission belt. When the transmission belt is tensioned, the rotation of the output shaft 21 can drive the pulley 30 to rotate synchronously, thereby driving the transmission belt to drive the other end pulley to rotate synchronously.

[0034] In one or more embodiments of the present disclosure, the second mounting seat further includes a support body for supporting the shaft support part 220. Figure 4A perspective view of the support body according to an embodiment of the present disclosure is shown. As Figure 4 As shown, in one or more embodiments of the present disclosure, the second mounting base includes a support body 240 extending from the other side of the motor fixing portion 210 plate body towards the shaft support portion 220, the shaft support portion 220 is mounted on the support body 240, the support body 240 is connected with the motor fixing portion 210 through the support body 240, and the support body 240 is arranged between the motor fixing portion 210 and the shaft support portion 220. In one or more embodiments of the present disclosure, the support body 240 can be one support rod, support frame, support shell or hollow support column arranged on the side of the output shaft, or can be a plurality of support rods arranged around the output shaft, or can be a support frame, support shell or hollow support column arranged around the output shaft, and the support body 240 can even be any combination of the foregoing structures. In this way, the support body not only supports the installation of the shaft support portion, but when the support body is arranged around the output shaft, the pulley mounted on the output shaft can also be protected in the support body. In one or more embodiments of the present disclosure, a side support structure 241 for supporting the installation of the shaft support portion 220 is arranged at the extension end of the support body 240. For example, the side support structure can be a structure mounted on one or more support rods, the side support structure can also be a structure mounted on a support frame, support shell or support column, and the side support structure can also be a face of the support shell or support column opposite to the motor fixing portion 210. The bearing of the shaft support portion 220 can be directly pressed on the side support structure 241, or can be indirectly mounted on the side support structure 241 through a bearing seat. In the case of indirect mounting, the side support structure 241 further includes an opening or passage extending through the side support structure in the axial direction of the output shaft, so that the output shaft can pass through the passage to reach the shaft support portion 220 and be rotatably connected with the bearing. In this way, when the motor is mounted on the second mounting base, the distal end of the output shaft is sufficiently supported, reducing deformation or breakage of the output shaft.

[0035] In one or more embodiments of the present disclosure, the output shaft passing through the through hole of the motor fixing part can pass through from one side of the support body and be rotationally connected with the shaft support part installed on the support body, for example, pass through from one side of a single support rod, support frame, support shell or hollow support column, and the like, and one or more spaces between the motor fixing part and the shaft support part, i.e., the transmission belt passing part, through which the transmission belt passes, are formed. In one or more embodiments of the present disclosure, the output shaft passing through the through hole of the motor fixing part can also pass through one or more spaces formed inside the support body and be rotationally connected with the shaft support part installed on the support body, for example, pass through one or more spaces formed between a plurality of support rods, or pass through a space formed inside a support frame, support shell or hollow support column arranged around the output shaft, and the like, and one or more spaces formed between the plurality of support rods, i.e., the transmission belt passing part, through which the transmission belt passes, and the space formed inside the support frame, support shell or hollow support column arranged around the output shaft, i.e., the transmission belt passing part, through which the transmission belt passes. In one or more embodiments of the present disclosure, when the output shaft passes through the inner space surrounded by the support body, the transmission belt passing part includes a transmission belt passing hole that penetrates the support body in the radial direction of the output shaft. As Figure 4As shown, in one or more embodiments of the present disclosure, the support body 240 can be a hollow cylindrical shell arranged around the output shaft, and the bottom surface of the cylindrical shell opposite the motor mounting portion 210, i.e., the side support structure 241 for mounting the bearing, is provided with a connecting hole to connect the bearing seat of the shaft support portion 220. The transmission belt passing portion 230 includes a transmission belt passing hole 231 that penetrates the support body 240 in the radial direction of the output shaft. Through the transmission belt passing hole 231, the pulley mounted on the output shaft surrounded by the support body 240 can be led out of the support body 240. It should be noted that the "radial penetration" described in the present disclosure refers to penetrating the support body in at least one direction from the position of the output shaft towards the outside of the support body in the radial direction of the output shaft. In the axial direction of the output shaft 21, the transmission belt passing hole can penetrate the support body or not (for example, one end is connected to the outside of the support body, the other end is closed, or both ends are closed). In one or more embodiments of the present disclosure, in the axial direction of the output shaft, one end of the transmission belt passing hole 231 close to the motor mounting portion does not penetrate the support body 240, and the other end close to the shaft support portion 220 penetrates the support body 240, to facilitate the installation and removal of the pulley and the transmission belt. In one or more embodiments of the present disclosure, the support body 240 further includes a mounting hole 242 that penetrates the support body 240 in the radial direction of the output shaft. When the installation space must be narrow, the mounting hole can be used for position adjustment, tightening screws, and other installation operations of the pulley and the belt, making installation more convenient. In the axial direction of the output shaft, the mounting hole 242 can penetrate the support body or not (for example, one end is connected to the outside of the support body, the other end is closed, or both ends are closed). In one or more embodiments of the present disclosure, in the axial direction of the output shaft, neither end of the mounting hole 242 penetrates the support body, so that the hole area of the second opening is small, which is beneficial to ensure the structural strength and stability of the support body.

[0036] In one or more embodiments of the present disclosure, the first mounting seat includes a motor mounting portion for connecting with the motor mounting portion to mount and fix the motor, and a motor seat mounting portion for mounting and connecting the adjustable motor seat to the embroidery machine. The motor mounting portion can be any structure that can be movably connected with the second mounting seat, and the motor seat mounting portion can be any structure that can be connected with the embroidery machine (e.g., the frame of the embroidery machine). Figure 5 A perspective view of the first mounting seat 100 according to an embodiment of the present disclosure is shown. As Figure 5As shown, the motor mounting portion 110 can be a plate body for connecting and fixing with the motor fixing portion of the second mounting seat, and the motor base mounting portion 120 can also be a plate body for connecting and fixing with the frame of the embroidery machine. The relative positions of the motor mounting portion 110 and the motor base mounting portion 120 can be designed and changed according to the installation position of the motor base, the positions of the belt pulleys at both ends of the transmission belt, and other conditions in the actual application scene. In one or more embodiments of the present disclosure, the motor mounting portion 110 is vertically arranged on one side of the motor base mounting portion 120, and the opposite side of the motor base mounting portion 120 is used to connect with the embroidery machine. A reinforcing rib 130 is connected between the motor mounting portion 110 and the motor base mounting portion 120 to improve the structural strength of the first mounting seat 100. The motor mounting portion 110 includes a through hole 111 that penetrates the motor mounting portion 110 along the axial direction of the output shaft. The second mounting seat can move in the through hole 111 to adjust the position of the second mounting seat on the first mounting seat.

[0037] Figure 6 A schematic diagram showing the movement of the second mounting seat relative to the first mounting seat according to an embodiment of the present disclosure is shown. As shown in FIG. 1, the second mounting seat 200 is connected with the first mounting seat 100 through the motor mounting portion 110 and the motor base mounting portion 120. The motor mounting portion 110 and the motor base mounting portion 120 can be connected with each other through the reinforcing rib 130. Figure 6 As shown, in one or more embodiments of the present disclosure, the motor fixing portion 210 can be connected with the motor mounting seat 110 to fix the second mounting seat on the first mounting seat, and the motor fixing portion 210 can also move relative to the motor mounting seat 110 to adjust the position of the second mounting seat on the first mounting seat. The motor fixing portion 210 and the shaft support portion 220 of the second mounting seat are respectively arranged on both sides of the through hole 111, and the support body 240 between the motor fixing portion 210 and the shaft support portion 220 penetrates the through hole 111 along the radial direction of the output shaft. The length of the through hole 111 should be greater than the length of the support body 240, so that the support body 240 can move in the through hole 111 to tension the transmission belt. In the radial direction of the output shaft, the through hole 111 can penetrate the motor mounting portion 210, or can not penetrate the motor mounting portion (for example, one end is connected to the outside of the motor mounting portion, and the other end is closed, or both ends are closed). Figure 7 A schematic diagram showing the adjustable motor base before and after adjustment according to an embodiment of the present disclosure is shown. As shown in FIG. 2, the second mounting seat 200 is connected with the first mounting seat 100 through the motor mounting portion 110 and the motor base mounting portion 120. Figure 7 As shown, the movement of the second mounting seat 200 in the through hole 111 towards or away from the motor base mounting portion can adjust the position of the motor fixed on the second mounting seat 200, thereby adjusting the position of the belt pulley mounted on the output shaft of the motor, and tensioning the transmission belt.

[0038] In some embodiments of the present disclosure, the adjustable motor base further includes a connecting structure for fixing the motor fixing portion 210 with the motor mounting portion 110. Figure 8 A schematic diagram showing the connection of the motor fixing portion 210 with the motor 20 and the motor mounting portion 110 according to an embodiment of the present disclosure is shown. As shown in FIG. 3, the motor fixing portion 210 is connected with the motor 20 through the motor fixing portion 210 and the motor mounting portion 110. Figure 8As shown, the motor fixing portion 210 is provided with a first connecting hole 212 for connecting with the motor 20 around the output shaft, and the motor 20 is also provided with a corresponding second connecting hole 22, and the motor can be fixed on one side of the motor mounting portion by connecting members such as bolts passing through the two connecting holes. In one or more embodiments of the present disclosure, the motor fixing portion is also provided with a third connecting hole 213 for connecting with the first mounting seat, and the motor mounting portion 110 of the first mounting seat is provided with a long hole 112 for connecting the motor fixing portion, and the long hole 112 extends along the radial direction of the output shaft. The connecting structure can include connecting members such as bolts (not shown in the figure) connecting the motor fixing portion 210 and the motor mounting portion 110 through the long hole 112 and the third connecting hole 213. After adjusting the relative arrangement of the second mounting seat on the first mounting seat, the connecting members are used for fixing.

[0039] The above has described the embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments.
