[0024] To maintain cutting accuracy and prevent deformation of the cut edge when cutting electrical installation rails, a limiting cutting mechanism is installed, such as... Figures 1-2 and Figure 4 The limiting cutting mechanism includes a cutting blade 2, which performs the cutting action on the guide rail.

[0025] The limiting cutting mechanism also includes a cutting bracket 201. A protective plate 202 is fixedly connected to the surface of the cutting bracket 201.

A cutting groove 206 is provided on the surface of the cutting bracket 201. The surface of the cutting blade 2 is slidably connected to the surface of the cutting groove 206.

[0028] Furthermore, multiple cutting cylinders 205 drive the cutting blade 2 to cut at a uniform speed. The cutting blade 2 cuts downwards from the side of the electrical mounting rail, improving cutting efficiency.

A limiting spring 209 is provided on the outer side of the limiting guide rod 207.

[0030] Furthermore, the cutting blade 2 moves downward, and at the same time, the limiting spring 209 drives the limiting slider 208 to limit and fix the electrical installation guide rail.

[0031] To automate the feeding and quantitative cutting of electrical installation rails and reduce manual operation, a feeding and metering mechanism is installed, such as... Figures 1-3 The conveying and metering mechanism includes a conveying roller 3, which guides and conveys the guide rail.

[0032] The conveying metering mechanism also includes a guide seat 301. The surface of the guide seat 301 is fixedly connected to the surface of the workbench 1. A guide groove 302 is provided on the surface of the guide seat 301. The surface of the conveying roller 3 is slidably connected to the surface of the guide seat 301. Both ends of the conveying roller 3 are rotatably connected to the surface of the cutting bracket 201. A conveying motor 303 is fixedly connected to the surface of the cutting bracket 201. The output shaft of the conveying motor 303 is fixedly connected to one end of the conveying roller 3 through a coupling. The conveying motor 303 is electrically connected to the control panel 203.

[0033] Furthermore, the conveyor motor 303 drives the conveyor roller 3 to rotate, conveying the electrical installation rail placed inside the guide chute 302.

[0034] A positioning rod 304 is fixedly connected to the surface of the cutting bracket 201. A meter counter 305 is rotatably connected to the surface of the positioning rod 304.

A collection box 306 is provided below the cutting blade 2. The surface of the collection box 306 is fixedly connected to the surface of the workbench 1.

[0035] Furthermore, a meter counter 305 is installed behind the conveyor roller 3 to measure the cutting length, and the cut guide rail is collected by the collection box 306 below.

[0036] By setting up a limiting cutting mechanism and a conveying metering mechanism, the limiting cutting mechanism cuts the guide rail with the cutting blade 2, and the conveying metering mechanism guides and conveys the guide rail with the conveying roller 3, thus solving the technical problem that the existing cutting device still requires manual control of the movement of the guide rail and the cutting of the trough.

[0037] Working principle:

[0038] Before use, adjust the cutting length and quantity via the control panel 203 located above the workbench 1. The conveyor motor 303 on the surface of the cutting bracket 201 drives the conveyor roller 3 to rotate. The protective plate 202 in front of the conveyor roller 3 protects the inside of the cutting device. The safety light curtain 204 in front of the conveyor roller 3 stops the cutting device immediately when a person is detected passing through, preventing injury to personnel. Push the electrical installation rail to be cut under the conveyor roller 3 through the guide groove on the surface of the guide seat 301. The conveyor roller 3 guides the electrical installation rail... The surface of the conveyor roller 3 engages with the guide rail, causing it to move backwards. A meter counter 305 (Jiakong JK72S) located behind the conveyor roller 3 rolls on the surface of the guide rail, measuring the length of the guide rail as it enters the rear. The measured length is fed back to the control panel 203 (Panasonic MK500). When one end of the guide rail extends beyond the guide seat 301 and reaches above the collection box 306, the conveyor motor 303 stops driving the conveyor roller 3, the guide rail stops moving and remains in place, and the cutting cylinder 205 located above the cutting bracket 201 drives the cutting blade 2 along... The surface of the cutting chute 206 moves downward, and the limiting slider 208 contacts the surface of the guide rail. The cutting blade 2 continues to move downward, and the surface of the cutting blade 2 presses down on the surface of the limiting slider 208 through the limiting spring 209 set on the outside of the limiting guide rod 207. The limiting slider 208, together with the guide seat 301, clamps the guide rail. The cutting blade 2 continues to move downward, cutting the end of the guide rail, keeping one end of the guide rail cut flush. The meter counter 305 is reset to zero and starts counting again. The cut guide rail is collected through the mobile phone box below. After the action is completed, the cutting cylinder 205 drives the cutting blade 2 to rise, and the limit guide rod 207 drives the limit slider 208 to relax the limit on the guide rail. The conveying motor 303 continues to drive the conveying roller 3 to rotate and convey the guide rail. When the meter counter 305 measures the cutting length set by the control panel 203, the conveying motor 303 stops again and the guide rail is cut at the same time. This is repeated until the cutting quantity set by the control panel 203 is reached. The conveying motor 303 drives the conveying roller 3 to rotate in the opposite direction and pushes the excess guide rail out from the front of the cutting device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
