Description

Technical Field

[0001] The present application relates to the field of mechanical transmission technology, and in particular to a motor base device. Background Art

[0002] In mechanical equipment, the motor is typically mounted on a motor base. The motor is typically used in conjunction with mechanical structures such as a motor reducer and pulleys to transmit motion. However, with traditional motors and motor bases, when a belt is used to connect the motor to a transmission device such as a reducer, if the distance between the motor and the pulley is too large, the belt becomes difficult to install. However, if the distance is too small, the belt becomes loose. Both situations shorten the belt's service life and lead to frequent failures.

[0003] Among the industrial machinery used in plastic product production, extruders are widely used in chemical fiber production lines, sheet production lines, pipe production lines, profile production lines, and more. Extruders are crucial equipment in plastic extrusion production and processing, and the stability of the extruder motor directly impacts the operating quality and stability of chemical fiber equipment.

[0018] In order to describe the technical content, structural features, achieved purposes and effects of the invention in detail, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the presence of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0019] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0020] Furthermore, in this application, spatially relative terms such as "under," "beneath," "under," "down," "above," "upper," "above," "higher," "side" (e.g., as in "sidewall"), etc., are used to describe the relationship of one element to another (other) element as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, an element described as "under" or "beneath" other elements or features would subsequently be positioned "above" the other elements or features. Thus, the exemplary term "under" can include both above and below orientations. Furthermore, the device can be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0021] This application relates to a motor base device for chemical fiber extrusion equipment, which is installed on the frame of the chemical fiber extrusion equipment. The motor base plate moves back and forth by rotating the screw rod to adjust the distance between the pulley and the motor, thereby adjusting the tension and parallelism between the motor and the pulley, and maintaining the belt in an optimal stress state.

[0022] See also Figure 1 、 2 As shown, the motor base device includes: a ground fixing base 2, a motor base frame 5, a motor base plate 4 movably mounted on the motor base frame 5, and a screw 10 rotatably mounted on the motor base frame 5. The motor base frame 5 is welded to the top of the ground fixing base 2, and the ground fixing base 2 is locked and fixed to the ground by expansion screws. The ground fixing base 2 can fix the motor to the ground to eliminate vibration, and the use of screws to fix it to the ground can also adjust the parallelism of the entire motor with the horizontal plane. In some embodiments, the ground fixing base 2 can also be locked and fixed to the frame of other mechanical equipment.

[0023] The motor base frame 5 has a square frame structure, which is located between the ground fixing base 2 and the motor base plate 4. Specifically, there is a pair of slides 3 on both sides of the motor base frame 5. The motor base plate 4 is placed on the motor base frame 5 and is in sliding friction contact with the upper surface of the pair of slides 3.

[0024] A cover plate 11 is fixedly mounted on the front side of the motor base frame 5, and a screw rod 10 is rotatably mounted on the cover plate 11. A screw rod seat 9 is fixedly mounted below the motor base plate 4. The screw rod seat 9 and the screw rod 10 form a screw-nut transmission, so that when the screw rod 10 is rotated, the screw rod seat 9 can drive the motor base plate 4 to move forward and backward relative to the motor base frame 5, thereby adjusting the position of the motor.

[0025] Specifically, the front end of the screw rod 10 has a pulley mounting end 8 for mounting a pulley, and the pulley mounting end 8 is located outside the motor base frame 5. In actual use, a pulley is coaxially fixed to the pulley mounting end 8 of the screw rod 10, and the motor is fixedly mounted on the motor base plate 4. The screw rod 10 is adjusted to adjust the position of the motor so that the distance and angle between the motor and the pulley are at the optimal fit, and then the belt is installed.

[0026] To facilitate adjustment and locking of the motor base plate, two pairs of slotted holes 13 are defined in the motor base plate 4, one on each side of the lead screw. These slotted holes 13 extend parallel to the axial direction of the lead screw 10, i.e., the front-to-back direction. Multiple locking bolts 1 are threadedly connected to the motor base frame 5. The nuts of these locking bolts 1 are located above the motor base 5. The lower portions of these locking bolts 1 extend through each slotted hole 13 and are threadedly secured to the flanges on either side of the motor base frame 5.

[0027] Preferably, the screw rod 10 is nitrided. By subjecting the screw rod to high-temperature heat treatment, its hardness, wear resistance and strength can be improved, and then it is blackened to prevent rust.

[0028] Further, a plurality of screw holes for mounting the motor are provided on the motor base plate 4. In order to cooperate with the use of motors of various models and sizes, a plurality of groups of screw holes that can respectively cooperate with different motors can be provided on the motor base plate, which has better versatility.

[0029] The welding of the motor base frame 5 and the ground fixing base 2 must be stress-relieved to lay a solid foundation for later deformation and ensure a smooth and beautiful weld. The screw seat is made of 45# steel, which has higher strength and deformation resistance.

[0030] The locking bolt 1 adopts a 12.9-grade strength bolt, which has the advantages of better locking performance, high strength, and prevention of thread slippage.

[0031] A fixing block is welded to the bottom of the motor base plate 4, which cooperates with the motor base frame 5 to prevent the motor from moving left and right when installed on the motor base frame 5. This would cause the motor pulley and the pulleys of transmission components such as the reducer to be out of line, causing the belt to wear rapidly due to oblique tension. The screw 10 is connected to the screw base 9. Adjusting the screw 10 can drive the motor base plate 4 to move back and forth, thereby adjusting the tension and parallelism between the motor and the pulley, so that the belt is in an optimal stress state, thereby significantly improving the operating quality and stability of the equipment.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
