[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] like Figure 1-Figure 3As shown, the embodiment of the present application provides a motor reducer supporting device, which is applied to a shredder in a cigarette factory. The shredder is used in the shredding process of the cigarette factory, and it cuts tobacco leaves or tobacco stems into required shredded tobacco and shredded stems. The shredder is provided with upper and lower copper chains, namely an upper copper chain and a lower copper chain. The upper and lower copper chains are arranged at a certain angle to form a wedge-shaped channel. The upper and lower copper chains cooperate with each other to convey and extrude the material, and extrude the material into a tobacco cake. Then, at the outlet of the equipment, a high-speed rotating shredder cuts the tobacco cake into shredded tobacco and shredded stems of required width. On the shredder, the upper and lower copper chains are driven by a driving motor and a reducer. The reducer is installed On the equipment frame, the driving motor is installed on the reducer. Since the material needs to be squeezed into a pancake shape, the driving force on the copper chain is relatively large, and the output shaft of the reducer needs to generate a large output torque. The reducer is connected to the equipment frame through its own casing, which causes a large concentrated stress to be generated locally in the reducer casing, which can easily cause deformation of the reducer casing and even cause cracks in the reducer casing, affecting the strength of the reducer casing and further affecting the installation strength of the reducer. The motor reducer support device of the present application is intended to improve the installation strength of the reducer and prevent the reducer casing from deforming during equipment operation.

[0023] The motor reducer support device includes a first mounting member 100 and a second mounting member 200. The first mounting member 100 is arranged in a flat shape. The first mounting member 100 is used to be installed on the equipment frame, and the plane where the flat direction of the first mounting member 100 is located is perpendicular to the axis of the output shaft of the motor reducer 90. The motor reducer 90 is installed on the flat side of the first mounting member 100, and one side of the shell of the motor reducer 90 is connected to the flat side of the first mounting member 100. The first mounting member 100 is connected to the equipment frame, thereby forming a connection between the outer side of the motor reducer 90 and the equipment frame. Preferably, the flat side of the first mounting member 100 is attached to the equipment frame, and the motor reducer 90 is arranged on the other side of the first mounting member 100. The flat side has a higher installation stability. The second mounting member 200 is also arranged in a flat shape. The second mounting member 200 is provided with a first mounting surface and a second mounting surface. The first mounting surface is used for attaching and installing on the equipment frame, and the second mounting surface is used for installing the motor reducer 90. One side of the outer side of the motor reducer 90 is arranged on the second mounting surface, and then the first mounting surface is attached to the equipment frame, thereby realizing the connection between one side of the motor reducer 90 housing and the equipment frame. Therefore, under the action of the first mounting member 100 and the second mounting member 200, two different positions of the motor reducer 90 housing can be connected to the equipment frame. When the output shaft of the motor reducer 90 outputs torque, the force strength of the motor reducer 90 housing can be effectively improved. The installation strength of the motor reducer 90 is greatly improved, and the deformation of the motor reducer 90 housing can be prevented. Preferably, the arrangement direction of the first mounting surface and the second mounting surface is coplanar with the axis of the output shaft of the motor reducer 90. In this embodiment, the first mounting surface and the second mounting surface are arranged linearly, and the linear arrangement direction of the two is coplanar with the output shaft of the motor reducer 90. It should be noted that the arrangement direction of the first mounting surface and the second mounting surface has no restriction requirements on the posture of the first mounting surface or the second mounting surface itself, as long as the arrangement direction of the two is coplanar with the output shaft axis of the motor reducer 90. For example, for the arrangement of the first mounting surface and the second mounting surface, the second mounting surface is farther away from the first mounting member 100 than the first mounting surface. When the first mounting surface When the vertical direction of the flat surface of a mounting member 100 is in the left-right direction, it is preferred that the first mounting surface and the second mounting surface are arranged roughly in the left-right direction as a whole. One side of the motor reducer 90 housing is connected to the first mounting member 100, and the other side of the motor reducer 90 housing is connected to the second mounting surface. The first mounting surface is attached to the equipment frame, the flat side of the first mounting member 100 is attached to the equipment frame, one side of the motor reducer 90 housing is set on the other flat side of the first mounting member 100, and the other side of the outer side of the motor reducer 90 is set on the second mounting surface. In this way, when the motor reducer 90 outputs torque, the first mounting member 100 and the second mounting member 200 apply limiting forces to the housing of the motor reducer 90 in two dimensions.The first mounting member 100 generates limiting stress on the motor reducer 90 housing in a plane perpendicular to the axis of the motor reducer 90 output shaft, and the second mounting member 200 generates limiting stress on the motor reducer 90 housing in a circumferential section of the motor reducer 90 output shaft, which greatly improves the stress strength of the motor reducer 90 housing, effectively improves the installation strength of the motor reducer 90 housing, and can avoid deformation or cracks in the motor reducer 90 housing.

[0024] Preferably, the flat surface of the first mounting member 100 is parallel to the first mounting surface, that is, the first mounting member 100 is attached to one side of the equipment rack, and the first mounting surface can be attached to different positions on the same side of the equipment rack. In this way, the installation operation is more convenient. More preferably, the first mounting surface is perpendicular to the second mounting surface. In this embodiment, the first mounting surface and the second mounting surface form an L-shape as a whole. When the side of the equipment rack for installing the first mounting member 100 and the second mounting member 200 is a vertical surface, the installation height of the second mounting member 200 on the equipment rack is lower than the installation height of the first mounting member 100 on the equipment rack. The second mounting member 200 includes a first connecting portion 201 and a second connecting portion. The first connecting portion 201 and the second connecting portion are both plate-shaped components. One side of the first connecting portion 201 is vertically connected to one side of the second connecting portion to form an L-shape. The outer side surface of the first connecting portion 201 constitutes the first mounting surface, and the outer side surface of the second connecting portion constitutes the second mounting surface. In this way, the first connection part 201 and the second connection part form an L-shaped structure as a whole, and the second mounting member 200 is located below the first mounting member 100 as a whole. Taking the left part of the second connection part connected to the top of the first connection part 201 as an example, the top side surface of the second connection part is the second mounting surface, the left side surface of the first connection part 201 is the first mounting surface, the left side surface of the first connection part 201 is attached and installed on the right side surface of the equipment rack, the first mounting member 100 is located above the second mounting member 200, and the left side surface of the first mounting member 100 is attached and installed on the right side surface of the equipment rack. In this way, the motor reducer 90 can be seated downward on the top side surface of the second connection part, the bottom of the outer shell of the motor reducer 90 is connected to the top side of the second connection part, the output shaft of the motor reducer 90 extends from the left side to the left, and the left side of the outer shell of the motor reducer 90 is connected to the left side of the first mounting member 100. In this way, the installation stability of the motor reducer 90 is further improved, and the installation operation is also convenient.

[0025] Preferably, a reinforcing rib 300 is arranged between the first connecting part 201 and the second connecting part, one side of the reinforcing rib 300 is connected to the first connecting part 201, and the other side of the reinforcing rib 300 is connected to the second connecting part. The reinforcing rib 300 is arranged at the connection between the first connecting part 201 and the second connecting part to improve the local connection strength. Two reinforcing ribs 300 are arranged, and the reinforcing ribs 300 are located at both ends of the inner angle of the corner where the first connecting part 201 and the second connecting part are connected. In this way, the load-bearing performance of the second mounting part 200 is greatly improved, which is beneficial to improving the installation stability of the motor reducer 90.

[0026] In one example, the second connection portion includes a first section 41 and a second section 42, and the first section 41 and the second section 42 are arranged in a direction away from the first connection portion 201. The second section 42 is farther away from the first connection portion 201 than the first section 41, and the thickness of the second section 42 is greater than the thickness of the first section 41. The reinforcing rib 300 extends to the area of ​​the first section 41. In this embodiment, the first connection portion 201 is a plate-like structure, and the second connection portion is arranged in a plate-like structure. The first connection portion 201 and the second connection portion form an L-shaped structure as a whole. The first section 41 is arranged in a plate-like structure, and the second section 42 is arranged in a plate-like structure. The flat surface of the first section 41 is parallel to the flat surface of the second section 42. The left part of the first section 41 is connected to the top of the first connection portion 201, and the right part of the first section 41 is connected to the left part of the second section 42. The reinforcing rib 300 is a plate-like component. 0 is connected to the right side of the first connection part 201, the left part of the reinforcing rib 300 extends to the right vertical area of ​​the first connection part 201, the top of the reinforcing rib 300 is connected to the bottom of the second connection part, the top of the reinforcing rib 300 extends to the first section 41 but not to the second section 42, and the thickness of the second section 42 is greater than the thickness of the first section 41. Preferably, the top of the first section 41 is flush with the top of the second section 42, the bottom of the second section 42 protrudes downward from the bottom of the first section 41, and the right side of the reinforcing rib 300 is transitionally connected to the second section 42. In this way, on the one hand, material can be saved, and on the other hand, under the reaction force of the output torque and the gravity of the motor reducer 90, the reinforcing rib 300 will apply a reaction support force to the bottom of the second connection part as a whole, so that a bonding stress is generated between the reinforcing rib 300 and the second section 42, thereby improving the overall load-bearing strength of the second connection part.

[0027] More preferably, it also includes a sleeve 500, which is arranged in a cylindrical shape, and the output shaft of the motor reducer 90 passes through the sleeve 500, and one end of the sleeve 500 is used to connect with the first mounting member 100. In an example, it also includes a first flange 601 and a second flange 602. The first flange 601 is coaxially arranged at one end of the sleeve 500, and the first flange 601 and the second flange 602 cooperate to connect the sleeve 500 to the first mounting member 100. One end of the sleeve 500 is connected to the first mounting member 100, and the other end of the sleeve 500 extends into the motor reducer 90. The outer shell of the motor reducer 90 contacts the outer wall of the sleeve 500, and the output shaft of the motor reducer 90 rotates inside the sleeve 500.

[0028] In this embodiment, the sleeve 500 is passed through by the output shaft of the power supply motor reducer 90, and the output shaft of the motor reducer 90 passes through the sleeve 500 and then passes through the first mounting member 100, and then a transmission structure such as a gear is set at the end of the output shaft of the motor reducer 90, and the left end of the sleeve 500 is coaxially connected to the first flange 601, and the left side of the first flange 601 abuts against the right side of the first mounting member 100, and a through hole is set on the first mounting member 100 for the output shaft of the power supply motor reducer 90 to pass through, and the second flange 602 abuts against the left side of the first mounting member 100, and the first mounting member 100 is fixed by a bolt assembly. The flange 601 and the second flange 602 are connected to realize the connection between the sleeve 500 and the first mounting member 100. The right part of the sleeve 500 can partially extend into the interior of the motor reducer 90 housing, and the outer wall of the sleeve 500 is in contact with the motor reducer 90 housing to form a limited contact. The output shaft of the motor reducer 90 passes through the sleeve 500 and the output shaft can rotate freely. The left side of the motor reducer 90 housing is also connected to the first mounting member 100 by bolts or screws, and the bottom of the motor reducer 90 housing and the second connecting part are connected by bolts or screws.

[0029] In this way, when the output shaft of the motor reducer 90 outputs torque, limiting stress will be generated between the sleeve 500 and the motor reducer 90 housing, between the motor reducer 90 housing and the first mounting member 100, and between the motor reducer 90 housing and the second mounting member 200. In this way, the force strength of the motor reducer 90 housing is greatly improved, the installation strength of the motor reducer 90 housing is significantly improved, and the motor reducer 90 housing is prevented from being deformed, etc., which is beneficial to improving the overall operating stability of the equipment.
