Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor technology, and in particular to a structure for improving the tension of a motor in a forging conveyor belt. Background Technology
[0002] In the forging production process, the conveyor belt is the core conveying equipment that realizes the transfer of forgings from the forging station to subsequent processes (such as cooling, inspection, and storage). The transmission method of motor-driven conveyor belt is widely used in the power transmission system of forging conveyor belts due to its advantages such as low cost and convenient installation.
[0003] However, in actual production scenarios, V-belts, as flexible transmission components, are prone to loosening due to factors such as long-term high-load operation, changes in ambient temperature, and aging of their own materials. At the same time, the motors of traditional forged conveyor belts mostly adopt a fixed installation structure. Once the motor position is locked to the bracket with bolts, it cannot be easily adjusted. This makes it difficult for operators to quickly fine-tune the motor position to restore the effective tension of the V-belt after it loosens.
[0004] When the V-belt becomes slack to a certain extent, the power output from the motor cannot be effectively transmitted to the conveyor belt drive wheel, directly causing the conveyor belt to stop or its transmission efficiency to drop significantly. At this point, the forgings continuously produced at the forging station cannot be transported out by the conveyor belt in time and will quickly accumulate at the conveyor belt feed end or designated station. As the number of accumulated forgings increases, the forgings produced later will exert a continuous compressive force on the accumulated forgings. Utility Model Content
[0005] The purpose of this invention is to provide a motor tensioning improvement structure for a forging conveyor belt to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution, which includes a main mounting bracket, a motor mounting base on the main mounting bracket, a motor body on the motor mounting base, a V-belt pulley on the transmission end of the motor body, and an adjustment component on the main mounting bracket, the adjustment component being located on one side of the motor mounting base.
[0007] As a preferred embodiment of this utility model, the main mounting bracket is provided with two pairs of mounting and moving slots, and the bottom of the motor mounting base is symmetrically provided with fixing base plates on both sides. The fixing base plates are provided with positioning holes corresponding to the mounting and moving slots, and bolt groups are inserted into the positioning holes and mounting and moving slots. The fixing base plates are fixed to the main mounting bracket by bolt groups.
[0008] As a preferred embodiment of this utility model, the adjustment component includes a mounting block disposed on the main mounting bracket, a screw cylinder disposed on the top of the mounting block, a jacking screw disposed on the internal thread of the screw cylinder, a tail block disposed at the tail end of the jacking screw, a movable hole being opened on the tail block, a lever being movably disposed in the movable hole, and limit blocks being provided at both the upper and lower ends of the lever.
[0009] In a preferred embodiment of this utility model, a stop plate is provided on the side of one of the fixed base plates corresponding to the position of the jacking screw.
[0010] In a preferred embodiment of this utility model, an indicator ruler is provided between the pair of mounting movable slots. The top of the indicator ruler is provided with a tension value. A fixed handle is movably provided at the end of the jacking screw away from the tail block. The fixed handle can rotate around the front end of the jacking screw. An indicator arrow is provided at the bottom of the fixed handle. The indicator arrow is attached to the indicator ruler.
[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: 1. This utility model uses a sliding motor mounting base and adjustment components to allow the operator to simply rotate the lever to drive the jacking screw and move the motor, quickly restoring the tension of the V-belt. The entire process can be completed in a short time without disassembling the bolts, thus preventing power interruption of the conveyor belt, fundamentally eliminating the problem of forging accumulation and extrusion, reducing production line downtime losses, and ensuring production continuity.
[0012] 2. This utility model uses a lever structure that allows a single person to drive and adjust the motor without tools, saving effort. At the same time, the motor fixing bolts only need to be loosened without disassembly, and can be tightened after adjustment to fix it. This design eliminates repeated disassembly and assembly steps, greatly simplifies the operation, and can be completed by ordinary personnel after simple training, reducing labor costs and operating threshold, and improving on-site adjustment efficiency.
[0013] 3. This utility model uses a preset standard tension value on a scale. The rotating fixed handle drives the indicator arrow to always be in contact with the scale, allowing the operator to intuitively judge the tension status and quickly adjust it to the standard value. This avoids adjustment errors, reduces abnormal wear and tear on the V-belt, V-belt pulley, and motor, significantly extends the equipment life, and reduces spare parts replacement costs.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0017] like Figure 1-6 As shown, the present invention proposes a motor tension improvement structure for a forging conveyor belt. It includes a main mounting bracket 1, which is a basic bearing component used to fix and connect with the frame body of the forging conveyor belt, providing stable support for the entire motor installation and adjustment system. At a preset position of the main mounting bracket 1, a motor mounting seat 2 for fixing the motor is assembled. The motor body 5 is directly mounted on the motor mounting seat 2 by bolt group 6, and a V-belt pulley 50 adapted to the conveyor belt drive mechanism is coaxially mounted on the transmission end of the motor body 5. The V-belt pulley 50 cooperates with the driven pulley of the conveyor belt to realize power transmission. To achieve adjustable motor position, the main mounting bracket 1 has two pairs of mounting sliding slots 10, which extend along the motor drive direction and provide a guide trajectory for the movement of the motor mounting base 2. Correspondingly, fixed base plates 20 are symmetrically welded to both sides of the bottom of the motor mounting base 2. The fixed base plates 20 have positioning holes 21 that correspond one-to-one with the positions of the mounting sliding slots 10. Bolt sets 6 are inserted through the positioning holes 21 and the mounting sliding slots 10. When the motor position is not adjusted to the correct position, the bolt sets 6 are not fully locked, allowing the fixed base plates 20 to slide along the mounting sliding slots 10. When the motor position is adjusted to the target position, tightening the bolt sets 6 will firmly fix the fixed base plates 20 to the main mounting bracket 1, ensuring the stability of the motor during operation. To allow the motor mounting base 2 to slide along the mounting groove 10, an adjustment component 3 is also provided on the main mounting bracket 1. This component is located on one side of the motor mounting base 2 and acts directly on the motor mounting base 2 to achieve tightness adjustment. The adjustment component 3 specifically includes a mounting block 30 welded to the main mounting bracket 1. A screw cylinder 31 with internal threads is vertically fixed to the top of the mounting block 30. A jacking screw 32 is threaded through the internal threads of the screw cylinder 31. The tail of the jacking screw 32 (the end away from the motor) is integrally formed with a tail block 3. 5. A movable hole 36 is provided on the tail block 35 along the horizontal direction. A tossing rod 37 is inserted into the movable hole 36. Limiting blocks 38 are welded to both the upper and lower ends of the tossing rod 37. The diameter of the limiting blocks 38 is larger than the diameter of the movable hole 36, which can prevent the tossing rod 37 from falling out of the movable hole 36. In use, by rotating the tossing rod 37, the jacking screw 32 can be driven to move along the axial direction of the screw barrel 31. Compared with directly rotating the screw, the setting of the tossing rod 37 is more labor-saving and is especially suitable for convenient operation in the forging production site. To ensure that the thrust of the jacking screw 32 can be stably transmitted to the motor mounting base 2, a backing plate 22 is welded to the side of one of the fixed base plates 20 corresponding to the position of the jacking screw 32. The end face of the backing plate 22 is polished to ensure that the end of the jacking screw 32 can fit tightly with the backing plate 22. When the jacking screw 32 is pushed along the screw barrel 31 towards the motor, it will push the fixed base plate 20 and the motor mounting base 2 as a whole to move along the mounting groove 10 through the backing plate 22, thereby driving the V-belt pulley 50 to move closer to or away from the driven pulley, so as to realize the tension adjustment of the transmission belt. Conversely, when the jacking screw 32 is rotated in the opposite direction to make it move backward, the backing plate 22 can be loosened, which facilitates manual fine adjustment of the position of the motor mounting base 2. To further improve the accuracy of tension adjustment and avoid repeated trial adjustments, an indicator ruler 4 is embedded in the main mounting bracket 1 between one pair of mounting movable slots 10. The top of the indicator ruler 4 is printed with tension values 40 distributed along the length direction (this value is preset according to the standard tension requirements of the conveyor belt). At the same time, a fixed handle 33 is movable at the bottom of the end of the jacking screw 32 away from the tail block 35. The fixed handle 33 can rotate around the top of the jacking screw 32. An indicator arrow 34 extends vertically downward from the bottom of the fixed handle 33. The tip of the indicator arrow 34 is attached to the surface of the indicator ruler 4. When rotating the jacking screw 32 to adjust the motor position, the operator can intuitively judge the current tension of the belt by the tension value 40 indicated by the indicator arrow 34, and quickly adjust it to the standard value, which greatly improves the adjustment efficiency and accuracy and reduces the risk of equipment failure due to improper tension.

Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
