Description

Technical Field

[0001] This utility model relates to the field of patterned roller processing technology, and in particular to a grinding machine specifically designed for the fine finishing of patterned roller surfaces. Background Technology

[0002] Steel plates with patterns on their surface are called patterned plates. The patterns include lentil-shaped, diamond-shaped, round bean-shaped, and mixed flat and round shapes, with the lentil-shaped being the most common. Patterned plates have many advantages such as beautiful appearance, anti-slip properties, enhanced performance, and steel saving. They are widely used in transportation, construction, decoration, equipment base plates, machinery, shipbuilding and other fields. When rolling patterned plates, patterned rolls must be installed on the work rolls or lower work rolls of the last stand of the finishing mill.

[0003] A patent with publication number CN213795196U discloses a CNC grinding machine for processing patterned rollers, including a CNC grinding machine base, rollers, multiple grinding heads, and milling cutters. Two fixed plates are fixedly connected to the top of the CNC grinding machine base. Rotation holes are formed on the outer walls of the fixed plates, and roller clamping rods are rotatably connected to the inner walls of the rotation holes. A first motor is fixedly connected to the end of one of the roller clamping rods, and a positioning groove is formed at the end of the roller clamping rod. The inner walls of the two positioning grooves are fixedly set with the rollers. Two fixing grooves are formed at the bottom of the CNC grinding machine base. This device, through the cooperation of the fixed plates, roller clamping rods, positioning grooves, threaded rods, a first moving table, a second moving table, and an adjustment device, mounts multiple grinding heads on the outer walls of the rollers. The position of the grinding heads is adjusted by rotating the rollers, thereby achieving the purpose of changing the grinding heads. Compared to the traditional method of directly changing grinding heads, this device is more time-saving, labor-saving, and convenient.

[0004] The applicant found that the above-mentioned patent did not describe in detail the dust removal method during the engraving process. According to the existing pattern roller surface finishing grinding machine, in order to avoid the impact of the engraving debris on the pattern, a high-pressure fan is usually set on one side of the equipment to blow away the debris in time to avoid this problem. However, this dust removal method will cause dust to enter the air, posing a safety hazard to the surrounding workers. Based on this, we propose an improvement for a pattern roller surface finishing grinding machine. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding machine specifically for finishing the surface of patterned rollers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grinding machine specifically for precision machining of patterned roller surfaces, comprising a frame, a lead screw rotatably connected to the upper end face of the frame near the front side, an engraving machine threaded onto the outer wall of the lead screw, a support frame fixedly connected to the upper end of the frame, an air guide tube fixedly connected between the two vertical plates of the support frame, a dust suction hood fixedly connected to the lower end face of the air guide tube, an exhaust fan provided on one side of the outer wall of the support frame, the output end of the air guide tube fixedly connected to the input end of the exhaust fan, an exhaust pipe fixedly connected to the output end of the exhaust fan, and a center clamp one and a top clamp two rotatably and slidably connected to the two vertical plates of the support frame, respectively, with a roller sleeved between the center clamp one and the top clamp two.

[0007] Through the above technical solution, when the exhaust fan is working, it can drive the airflow from the dust collection hood into the air guide tube, and then discharge it through the exhaust pipe. Therefore, the waste chips and dust generated by roller engraving can be removed in time, avoiding any impact on the health of the surrounding workers.

[0008] As a further description of the above technical solution:

[0009] A motor is fixedly connected to the upper end of the frame, one end of the lead screw is fixedly connected to the output shaft of the motor, and the lower end of the engraving machine is slidably attached to the upper end of the frame.

[0010] The above technical solution allows the engraving machine to move by rotating the lead screw driven by the motor. The lower end of the engraving machine is in contact with the upper end of the frame to prevent it from flipping over with the lead screw, which would affect the engraving accuracy.

[0011] As a further description of the above technical solution:

[0012] There are multiple dust hoods, and all of the dust hoods are positioned above the roller.

[0013] Through the above technical solution, the dust collection hood can promptly remove the waste chips and dust generated during roller engraving.

[0014] As a further description of the above technical solution:

[0015] An installation component is fixedly connected to the outer wall of the support frame. The exhaust fan is fixedly connected to the installation component. A drive motor is fixedly connected to the outer wall of one vertical plate of the support frame. The output end of the drive motor is fixedly connected to one end of the first top clamp. An installation frame is fixedly connected to the outer wall of the other vertical plate of the support frame. A cylinder is fixedly connected to the installation frame. The output end of the cylinder is fixedly connected to one end of the second top clamp.

[0016] Through the above technical solution, the cylinder can drive the top clamp two to extend, and cooperate with the center clamp one to hold and fix the roller. Then, the drive motor is started to drive the center clamp one to rotate, which in turn drives the roller to rotate, which facilitates processing.

[0017] As a further description of the above technical solution:

[0018] A rectangular slot is provided in the middle of the frame, and a dust collection box is fixedly connected to the lower end of the frame. The rectangular slot is located above the dust collection box, and a filter frame is slidably sleeved inside the dust collection box. The exhaust end of the exhaust pipe passes through one side of the dust collection box.

[0019] The above technical solution collects the waste and dust discharged from the exhaust pipe through the dust collection box, and the airflow is filtered through the filter screen in the filter frame and continues to rise through the rectangular slot to form an airflow circulation, thereby improving the waste cleaning efficiency.

[0020] As a further description of the above technical solution:

[0021] The filter frame is positioned above the air outlet of the exhaust pipe, and support plates are fixedly connected to both inner walls of the dust collection box. The filter frame is slidably mounted on the support plates.

[0022] The above technical solution uses a support plate to provide auxiliary support for the filter frame, making it easier for the filter frame to slide inside the dust collection box.

[0023] This utility model has the following beneficial effects:

[0024] 1. Compared with existing technologies, this grinding machine, which is specifically designed for the fine finishing of patterned roller surfaces, effectively removes the debris generated during the engraving process by absorbing it through the coordinated structure of a support frame, air duct, dust hood, exhaust fan, and exhaust pipe, thus preventing it from entering the air and affecting the surrounding workers.

[0025] 2. Compared with existing technologies, this grinding machine specifically designed for the finishing of patterned roller surfaces, by setting up a dust collection box, support plate, and filter frame structure in conjunction with an exhaust fan, can guide debris into the dust collection box through the exhaust pipe for centralized collection, avoiding the need for dust collection. At the same time, the filter screen on the filter frame can filter waste debris, facilitating airflow through the rectangular slot to flow upward, which can further assist the airflow in drawing waste debris into the dust collection hood, making it convenient and time-saving. The support plate can easily support the filter frame, making it easy to disassemble and assemble, and facilitating the cleaning of the filter screen. Attached Figure Description

There is an exhaust fan 6, and the output end of the air guide tube 3 is fixedly connected to the input end of the exhaust fan 6. The output end of the exhaust fan 6 is fixedly connected to the exhaust pipe 7. After the exhaust fan 6 is turned on, the waste chips and dust generated by grinding are sucked into the air guide tube 3 through the dust suction hood 4, and then discharged through the exhaust pipe 7 to prevent the waste chips and dust from entering the air. The two vertical plates of the support frame 2 are respectively rotatably and slidably connected to the top clamp 1 9 and the top clamp 2 12. A roller 13 is sleeved between the top clamp 1 9 and the top clamp 2 12.

[0033] Through the above technical solution, when the exhaust fan 6 is working, it can drive the airflow from the dust collection hood 4 into the air guide duct 3, and then discharge it through the exhaust pipe 7. Therefore, the waste chips and dust generated by the roller 13 engraving can be removed in time, avoiding the impact on the health of the surrounding workers.

[0037] A rectangular slot 16 is provided in the middle of the frame 1. A dust collection box 17 is fixedly connected to the lower end face of the frame 1. The rectangular slot 16 is located above the dust collection box 17. A filter frame 19 is slidably sleeved inside the dust collection box 17. The air outlet of the exhaust pipe 7 is set through one side of the dust collection box 17. The dust collection box 17 collects the waste and dust discharged from the exhaust pipe 7. The airflow is filtered through the filter screen in the filter frame 19 and continues to rise through the rectangular slot 16 to form an airflow circulation, thereby improving the waste cleaning efficiency.

[0038] The filter frame 19 is set above the air outlet of the exhaust pipe 7. Support plates 18 are fixedly connected to the inner walls on both sides of the dust collection box 17. The filter frame 19 is slidably set on the support plates 18. The support plates 18 provide auxiliary support for the filter frame 19, making it easy for the filter frame 19 to slide in the dust collection box 17.

[0039] Working principle: One end of the roller 13 is sleeved on the outer end of the top clamp 9. Then, the cylinder 11 drives the top clamp 12 to extend and hold the other end of the roller 13 in place. Then, the drive motor 8 is started to drive the top clamp 9 to rotate, which in turn drives the roller 13 to rotate. At the same time, the motor drives the lead screw 14 to rotate and control the engraving machine 15 to move and engrave the surface of the roller 13. At the same time, the exhaust fan 6 is started to draw air. The waste generated by the engraving is drawn into the air guide duct 3 through the dust suction hood 4, and then discharged into the dust collection box 17 through the exhaust pipe 7. After the airflow is filtered by the filter screen on the filter frame 19, it continues to rise through the rectangular slot 16, thus forming an airflow circulation, which can better carry the waste into the air guide duct 3.
