Description

Technical Field

[0001] This utility model belongs to the field of servo cutter technology, and in particular relates to a servo cutter mechanism. Background Technology

[0002] Plastic water spray plates are mainly used inside cooling equipment such as cooling towers or chillers to facilitate heat exchange. They are primarily made of corrosion-resistant plastics such as polypropylene or polyvinyl chloride, and are low in cost and easy to install and maintain.

[0003] In the preparation of plastic water spray sheets, it is necessary to cut the molded water spray sheets. During the cutting process, a cutter is used to cut the water spray sheets. In existing equipment, the cutter is generally driven by a cylinder. This adjustment method mainly relies on the operation of the cylinder. However, the cylinder has a short service life, requires frequent maintenance, and the cutting stability is seriously dependent on the stability of the air pressure. Moreover, the adjustment is cumbersome and inconvenient to use.

[0004] In view of this, we propose a servo-driven cutting mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a servo cutting mechanism to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a servo cutting mechanism, including a frame, a hydraulic cylinder detachably connected to the outside of the frame, and a fixing frame fixedly installed at the output end of the hydraulic cylinder; A linear guide rail is fixedly installed on the inner wall of the fixed frame. A fixed seat is slidably connected to the outer surface of the linear guide rail. A blade holder is fixedly installed on the lower surface of the fixed seat. A cutting blade is detachably connected to the outside of the blade holder. A positioning plate one and a positioning plate two are fixedly installed on one side of the fixed seat, respectively. The fixed frame has a drive shaft and a driven shaft rotatably connected inside. A motor synchronous pulley is fixedly installed on the outer surface of the drive shaft, and a tension synchronous pulley is fixedly installed on the outer surface of the driven shaft. Both the motor synchronous pulley and the tension synchronous pulley are covered with synchronous belts, and a clamping plate is slidably connected to the outer surface of the synchronous belts.

[0007] In this technical solution, a linear guide rail is used to support and limit the fixed seat, and a clamping plate is used to fix the timing belt between positioning plate one and positioning plate two. At this time, the fixed seat moves with the rotation of the timing belt, and the timing belt driven by the servo motor realizes the rapid adjustment of the cutter.

[0008] In the above technical solution, a fixing rod is detachably connected inside the frame, and a support ring is slidably connected to the outer surface of the fixing rod. The outer surface of the support ring is fixedly installed with the outer surface of the fixing frame.

[0009] In this technical solution, the fixing rod and the support ring can support the fixing frame and improve the stability of the fixing frame when it moves.

[0010] In the above technical solution, the active shaft and the driven shaft are located at the two ends of the fixed frame, and a servo motor assembly is fixedly installed at one end of the active shaft and fixed to one side of the fixed frame.

[0011] In this technical solution, the servo motor assembly can control the rotation of the drive shaft and the rotation of the synchronous belt to control the position of the cutter.

[0012] In the above technical solution, the linear guide rail is further defined as an I-beam structure with through slots at both ends, and the fixing seat slides linearly on both sides of the linear guide rail.

[0013] In this technical solution, the linear guide rail can limit and support the fixed seat, restricting the fixed seat to only be able to move in a straight line.

[0014] In the above technical solution, the synchronous belt is made of polyurethane as a whole, and a high-strength steel wire core is provided inside the synchronous belt as a reinforcing layer.

[0015] In this technical solution, the timing belt can control the movement of the cutter, making the operation faster.

[0016] In the above technical solution, the positioning plate one and the positioning plate two are arranged vertically, one side of the timing belt is located between the positioning plate one and the positioning plate two, and the internal thread of the positioning plate one is connected with multiple sets of fixing bolts.

[0017] In this technical solution, the timing belt can be fixed using fixing bolts, at which point both positioning plate one and positioning plate two are fixed to one side of the timing belt.

[0018] In the above technical solution, further, the adjacent outer surfaces of the clamping plate and the second positioning plate are provided with a grid-like anti-slip texture, the interior of the clamping plate is provided with a positioning hole, and one end of the fixing bolt is in contact with the interior of the positioning hole.

[0019] In this technical solution, the clamping plate and the positioning plate can clamp and fix the timing belt, and can stably connect the fixing seat and the timing belt.

[0020] The beneficial effects of this utility model are: 1. This servo cutter mechanism, through the cooperation between the synchronous belt and the linear guide rail, uses the linear guide rail to limit the movement trajectory of the fixed seat, so that the fixed seat and the cutter can only move in a straight line. The fixed seat and the synchronous belt are connected by a clamping plate. The rotation of the synchronous belt can control the rapid movement of the cutter outside the linear track, which can effectively improve the cutting speed and stability, realize the function of improving the stability of the cutter adjustment, and help to extend the service life during operation.

[0021] 2. This servo cutting mechanism, through the setting of components such as fixing bolts, has a long maintenance-free cycle for the servo motor, which can increase the service life during adjustment. The position of the clamping plate can be adjusted by using the fixing bolts. The timing belt is placed between positioning plate one and positioning plate two, and then the fixing bolts are tightened. At this time, the fixing bolts can connect the fixing seat to the timing belt, making installation and disassembly relatively convenient. Attached Figure Description
