Description

Technical Field

[0001] This utility model relates to the field of key production, and in particular to a conveying mechanism for a key polishing machine. Background Technology

[0002] A key polishing machine is a device used to polish the surface of keys. It removes burrs, rust, scratches, and other imperfections from the key surface using mechanical or chemical methods, resulting in a smooth and shiny finish. During polishing, a conveyor mechanism transports the key blank to the polishing head. The conveyor mechanism uses a conveyor belt, and a mold for placing the key blank is set on the surface of the conveyor belt. The key blank is placed in a groove within the mold and then transported to the polishing head for polishing.

[0003] Existing conveyor mechanisms are inconvenient for tension adjustment. The drive rollers of the conveyor mechanism are all fixed to the conveyor frame with bolts. When adjusting the tension of the conveyor belt, it is necessary to remove the bolts at both ends of the drive roller, move the drive roller to the required position, and then tighten the bolts at both ends. The adjustment process is cumbersome, increases workload, and reduces adjustment efficiency. Moreover, this adjustment method makes it difficult to ensure that the two ends of the drive roller are in the same position, causing the drive roller to tilt and affecting the conveying effect. It is also inconvenient to change the mold. Generally, key molds can only hold moving key blanks. When polishing different key blanks, the mold needs to be changed. However, the mold is generally fixed with multiple bolts, which makes it difficult to change, increases workload, and reduces change efficiency. In order to solve the above problems, we propose a conveyor mechanism for a key polishing machine. Utility Model Content

[0004] The purpose of this invention is to provide a conveying mechanism for a key polishing machine, which has the advantages of easy tension adjustment and easy mold replacement.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a key polishing machine conveying mechanism, including a support frame, a conveying mechanism provided on the inner wall of the support frame, a telescopic frame slidably sleeved on the inner wall of the support frame, a screw threadedly connected to the inner wall of the telescopic frame, and the screw rotatably sleeved with the inner wall of the support frame, a first bevel gear fixedly sleeved at one end of the screw, a second bevel gear meshing with the surface of the first bevel gear, and a rotating shaft fixedly sleeved at the axis of the second bevel gear, and the rotating shaft rotatably sleeved with the inner wall of the support frame.

[0006] By adopting the above technical solution, by loosening the fixing bolts and rotating the turntable, the rotating shaft drives the second bevel gear to rotate. The rotation of the second bevel gear drives the first bevel gear to rotate the screw. The rotation of the screw drives the telescopic frame to move the second transmission roller. This method can facilitate the adjustment of tension, reduce the workload, improve the adjustment efficiency, and ensure the adjustment accuracy.

[0007] The present invention is further configured such that: a plurality of fixed seats are bolted to the surface of the conveying mechanism; a mold is provided on the surface of the fixed seats; four mounting rods are slidably sleeved on the inner wall of the fixed seats, and one end of the mounting rod is bolted to the surface of the mold; two sliding grooves are formed on the inner wall of the fixed seats; a sliding rod is slidably connected between the inner walls of the sliding grooves; a bidirectional lead screw is threaded to the inner wall of the sliding rod, and the bidirectional lead screw is rotatably sleeved with the inner wall of the fixed seats; a fixed rod is bolted to the surface of the sliding rod, and the fixed rod is inserted into the inner wall of the mounting rod.

[0008] By adopting the above technical solution, the bidirectional lead screw is rotated to drive the sliding rod to move in opposite directions. The movement of the sliding rod in opposite directions causes the fixed rod to disengage from the mounting rod, allowing the mold to be removed and replaced. This method facilitates mold replacement, as only the rotating head needs to be turned to replace the mold, reducing workload and improving replacement efficiency.

[0009] The present invention is further configured such that: the conveying mechanism includes a first transmission roller and a second transmission roller, both ends of the first transmission roller are rotatably sleeved with the inner wall of the support frame, both ends of the second transmission roller are rotatably sleeved with the inner wall of the telescopic frame, one end of the first transmission roller is bolted with a motor, and the motor is bolted to the surface of the support frame, and the surfaces of the first transmission roller and the second transmission roller are connected to a conveyor belt, and the surface of the conveyor belt is bolted to a fixed seat.

[0010] By adopting the above technical solution and setting up a conveying mechanism, it is easy to transport the key blank and facilitate polishing.

[0011] The present invention is further configured such that: a fixing block is rotatably sleeved on the surface of the rotating shaft, and the fixing block is bolted to the surface of the support frame; a fixing bolt is threadedly connected to the inner wall of the fixing block, and the inner end of the fixing bolt is in contact with the surface of the rotating shaft.

[0012] By adopting the above technical solution, the rotating shaft is fixed by setting a fixing block and fixing bolts, thereby improving stability.

[0013] The present invention is further configured such that a turntable is bolted to one end of the rotating shaft.

[0014] By adopting the above technical solution, a turntable is set up to facilitate the rotation of the shaft.

[0015] The present invention is further configured such that a rotating head is bolted to one end of the bidirectional lead screw.

[0016] By adopting the above technical solution, a rotating head is set up to facilitate the rotation of the bidirectional lead screw.

[0017] The present invention is further configured such that a support plate is bolted between the inner walls of the support frame.

[0018] By adopting the above technical solution, the conveyor belt is supported by a support plate, thereby improving the stability of the conveying process.

[0019] The present invention is further configured such that: a slider is bolted to the surface of the telescopic frame, and a groove is slidably connected to the surface of the slider, and the groove is formed on the inner wall of the support frame.

[0020] By adopting the above technical solution, the sliding block and slide groove are set to prevent the telescopic frame from shifting and improve stability.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model achieves the purpose of easy tension adjustment by loosening the fixing bolts, rotating the turntable to make the rotating shaft drive the second bevel gear to rotate, the rotation of the second bevel gear to drive the first bevel gear to rotate, and the rotation of the screw to move the telescopic frame to move the second transmission roller. This reduces the workload, improves the adjustment efficiency, and ensures the adjustment accuracy.

[0023] 2. This utility model achieves the purpose of convenient mold replacement by rotating the rotating head to make the bidirectional lead screw drive the sliding rod to move in opposite directions. The movement of the sliding rod in opposite directions causes the fixed rod to disengage from the mounting rod, thereby removing and replacing the mold. The mold can be replaced simply by rotating the rotating head, which reduces the workload and improves the efficiency of replacement. Attached Figure Description

Both ends of the first transmission roller 15 are rotatably sleeved with the inner wall of the support frame 1, and both ends of the second transmission roller 17 are rotatably sleeved with the inner wall of the telescopic frame 3. One end of the first transmission roller 15 is bolted with a motor 18, and the motor 18 is bolted to the surface of the support frame 1. The surfaces of the first transmission roller 15 and the second transmission roller 17 are connected to a conveyor belt 19, and the surface of the conveyor belt 19 is bolted to the fixed seat 8. By setting the conveying mechanism 2, it is convenient to convey the key blank and facilitate polishing.
