Description

Technical Field

[0001] The invention belongs to the technical field of high and low voltage switch cabinets, and relates to a semi-automatic laser feeder, in particular to a semi-automatic laser feeder for the production and processing of high and low voltage switch cabinet accessories. Background Art

[0002] As the name suggests, low-voltage switchgear is a device that connects high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for each power user. The low-voltage cabinets are nothing more than some protective devices such as switches and circuit breakers assembled into one electrical device.

[0003] In the prior art, after the casting process of high and low voltage switch cabinet accessories is completed, the surface temperature of the high and low voltage switch cabinet accessories is relatively high, and the accessories cannot be fed in time to complete the assembly of the high and low voltage switch cabinets. Instead, the high and low voltage switch cabinet accessories after casting need to be placed in a transfer box for cooling. The cooling process takes a certain amount of time, which greatly reduces the efficiency of the processing and production of high and low voltage switch cabinet accessories. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that after the casting process of high and low voltage switch cabinet accessories is completed, the surface temperature of the high and low voltage switch accessories is high, and the accessories cannot be fed in time to complete the assembly of the high and low voltage switch cabinets. Instead, the high and low voltage switch cabinet accessories after casting need to be placed in a transfer box for cooling, and the cooling process takes a certain amount of time, which greatly reduces the efficiency of the processing and production of high and low voltage switch cabinet accessories. A semi-automatic laser feeder for the production and processing of high and low voltage switch cabinet accessories is proposed.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A semi-automatic laser feeder for the production and processing of high and low voltage switch cabinet accessories, comprising a bracket, a receiving hopper, a condensation inlet pipe, a condensation outlet pipe, a water inlet pipe, a water outlet pipe, a diversion chamber, and a heat dissipation chamber. The receiving hopper is arranged on the bracket, and the receiving hopper is located directly below the discharging port of the cracking furnace. The top of the receiving hopper is a square structure, and the bottom is a conical structure.

[0007] A transport assembly is arranged directly below the discharge port of the receiving hopper, and the transport assembly includes a mounting frame, a conveyor belt, a driving motor, an active conveyor shaft, a roller, and a driven conveyor shaft. Two groups of mounting frames are arranged, and the mounting frames are arranged on the brackets. The active conveyor shaft and the driven conveyor shaft are respectively installed at both ends of the two groups of mounting frames, and the active conveyor shaft is connected to the output end of the driving motor. The driving motor is arranged on one group of mounting frames, and the output end of the driving motor is connected to the active conveyor shaft. The active conveyor shaft is connected to the driven conveyor shaft through the conveyor belt. Multiple groups of rollers are arranged side by side between the active conveyor shaft and the driven conveyor shaft, and the two ends of the rollers are rotatably arranged on the mounting frames respectively. The mounting frame is a hollow structure with a diverter cavity arranged inside, and the rollers are a hollow structure with a heat dissipation cavity arranged inside, and the diverter cavity is connected to the heat dissipation cavity.

[0008] Preferably, the side wall of the receiving hopper is a hollow structure, a condensation chamber is arranged in the side wall of the receiving hopper, a condensation inlet pipe is arranged at the bottom of one side wall of the receiving hopper, a condensation outlet pipe is arranged at the top of the other side wall of the receiving hopper, a guide plate is arranged in the middle of the inner cavity of the receiving hopper, the guide plate is an inverted V-shape, and an anti-slip layer is arranged on the inclined surface of the guide plate, two groups of rectangular discharge ports are formed between the bottom of the guide plate and the bottom of the receiving hopper, the guide plate is a hollow structure, and the inner cavity of the guide plate is connected to the condensation chamber in the receiving hopper.

[0009] Preferably, a water inlet pipe is installed on the side wall of one group of mounting frames, and a water outlet pipe is installed on the side wall of another group of mounting frames.

[0010] Preferably, a connecting plate is provided at one end of the two groups of mounting frames, and two groups of laser instruments are arranged side by side on the side wall of the connecting plate close to the conveyor belt, and the laser instruments are connected to the push mechanism signals.

[0011] Preferably, the pushing mechanism includes a pushing plate and a cylinder. The cylinder is symmetrically arranged on a mounting frame along the conveyor belt. The output end of the cylinder is connected to the pushing plate. The laser is communicatively connected to the cylinder. The pushing plate is located above the conveyor belt.

[0012] Preferably, the working method of the semi-automatic laser feeder comprises the following steps:

[0013] S1. After the high and low voltage switch cabinet accessories are cast, they first fall into the receiving hopper and fall along the guide channel between the receiving hopper and the guide plate. Since the guide plate is an inverted V-shaped, the inclined surface of the guide plate is provided with an anti-slip layer, so that the high and low voltage switch cabinet accessories are divided into two rows and fall on the conveyor belt. Since the side wall of the receiving hopper is a hollow structure, the inner wall of the receiving hopper is provided with a condensation cavity, the bottom side wall of the receiving hopper is provided with a condensation inlet pipe, and the other side wall of the receiving hopper is provided with a condensation outlet pipe. The inner cavity of the guide plate is connected with the condensation cavity in the receiving hopper. By introducing the condensation medium into the condensation inlet pipe, the condensation medium enters the condensation cavity in the receiving hopper and the inner cavity on the guide plate, and then is discharged from the condensation outlet pipe, so that the high and low voltage switch cabinet accessories after casting are cooled;

[0014] S2. High and low voltage switch cabinet accessories fall onto the conveyor belt along the rectangular discharge port. The high and low voltage switch cabinet accessories on the conveyor belt are transported by the driving motor driving the active transmission shaft to rotate. During the transportation of the high and low voltage switch cabinet accessories on the conveyor belt, the laser instrument detects whether the high and low voltage switch cabinet accessories in two rows are aligned. When the high and low voltage switch cabinet accessories are not aligned, the laser instrument transmits the signal to the cylinder, and the cylinder drives the push plate to work. The push plate pushes the offset high and low voltage switch cabinet accessories to the same horizontal line for neat loading;

[0015] S3. Since multiple groups of rollers are arranged side by side between the active transmission shaft and the driven transmission shaft, and the rollers are hollow structures with heat dissipation cavities arranged inside, condensed water enters the diversion cavity in the mounting frame through the water inlet pipe, and enters another group of mounting frames after passing through the heat dissipation cavity in the rollers, and is discharged from the water outlet pipe on the mounting frame of another group, so that the condensed water can further cool down the high and low voltage switch cabinet accessories being transported.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: after the high and low voltage switch cabinet accessories are cast, they first fall into the receiving hopper and fall along the guide channel between the receiving hopper and the guide plate. Since the guide plate is an inverted V-shape, the inclined surface of the guide plate is provided with an anti-skid layer, so that the high and low voltage switch cabinet accessories are divided into two rows and fall on the conveyor belt. Moreover, since the side wall of the receiving hopper is a hollow structure, the inner wall of the receiving hopper is provided with a condensation cavity, the bottom side wall of the receiving hopper is provided with a condensation inlet pipe, and the other side wall of the receiving hopper is provided with a condensation outlet pipe. The inner cavity of the guide plate is connected with the condensation cavity in the receiving hopper. By introducing the condensation medium into the condensation inlet pipe, the condensation medium enters the condensation cavity in the receiving hopper and the inner cavity on the guide plate, and then is discharged from the condensation outlet pipe, so that the high and low voltage switch cabinet accessories after the casting are cooled.

[0017] Then, the high and low voltage switch cabinet accessories fall onto the conveyor belt along the rectangular discharge port. The high and low voltage switch cabinet accessories on the conveyor belt are transported by the driving motor driving the active transmission shaft to rotate. During the transportation of the high and low voltage switch cabinet accessories on the conveyor belt, the laser instrument detects whether the high and low voltage switch cabinet accessories in two rows are aligned. When the high and low voltage switch cabinet accessories are not aligned, the laser instrument transmits the signal to the cylinder, and the cylinder drives the push plate to work. The push plate pushes the offset high and low voltage switch cabinet accessories to the same horizontal line for neat loading;

[0018] Since multiple groups of rollers are arranged side by side between the active transmission shaft and the driven transmission shaft, the rollers are of a hollow structure with a heat dissipation cavity arranged inside, so that condensed water enters the diversion cavity in the mounting frame through the water inlet pipe, enters another group of mounting frames after passing through the heat dissipation cavity in the rollers, and is discharged from the water outlet pipe on the mounting frame of the other group, so that the condensed water further cools the high and low voltage switch cabinet accessories being transported, thereby solving the problem in the prior art that after the casting process of the high and low voltage switch cabinet accessories is completed, the surface temperature of the high and low voltage switch accessories is high, and the accessories cannot be fed in time to complete the assembly of the high and low voltage switch cabinets. Instead, the high and low voltage switch cabinet accessories after casting need to be placed in a transfer box for cooling, and the cooling process takes a certain amount of time, thereby greatly reducing the efficiency of the processing and production of high and low voltage switch cabinet accessories.

[0032] The working method of the semi-automatic laser feeder comprises the following steps:

[0033] S1. After the high and low voltage switch cabinet accessories are cast, they first fall into the receiving hopper 2 and fall along the guide channel between the receiving hopper 2 and the guide plate 10. Since the guide plate 10 is an inverted V-shape, the inclined surface of the guide plate 10 is provided with an anti-slip layer 11, so that the high and low voltage switch cabinet accessories are divided into two rows and fall on the conveyor belt 5. Since the side wall of the receiving hopper 2 is a hollow structure, the inner wall of the receiving hopper 2 is provided with a condensation cavity, the bottom side wall of the receiving hopper 2 is provided with a condensation inlet pipe 3, and the other side wall of the receiving hopper 2 is provided with a condensation outlet pipe 13.

[0034] S2. The high and low voltage switch cabinet accessories fall onto the conveyor belt 5 along the rectangular discharge port. The high and low voltage switch cabinet accessories on the conveyor belt 5 are transported by the driving motor 6 driving the active transmission shaft 7 to rotate. During the transportation of the high and low voltage switch cabinet accessories on the conveyor belt 5, the laser instrument 12 detects whether the high and low voltage switch cabinet accessories in two rows are aligned. When the high and low voltage switch cabinet accessories are not aligned, the laser instrument 12 transmits a signal to the cylinder 20, and the cylinder 20 drives the push plate 19 to work. The push plate 19 pushes the offset high and low voltage switch cabinet accessories to be on the same horizontal line for neat loading;

[0035] S3. Since multiple groups of rollers 8 are arranged side by side between the active transmission shaft 7 and the driven transmission shaft 9, and the rollers 8 are hollow structures with a heat dissipation cavity 17 arranged inside, the condensed water enters the diversion cavity 16 in the mounting frame 4 through the water inlet pipe 14, and then enters another group of mounting frames 4 after passing through the heat dissipation cavity 17 in the rollers 8, and is discharged from the water outlet pipe 15 on the mounting frame 4 of another group, so that the condensed water can further cool down the high and low voltage switch cabinet accessories being transported.

[0036] Working principle of the present invention: After the high and low voltage switch cabinet accessories are cast, they first fall into the receiving hopper 2 and fall along the guide channel between the receiving hopper 2 and the guide plate 10. Since the guide plate 10 is an inverted V-shape, the inclined surface of the guide plate 10 is provided with an anti-slip layer 11, so that the high and low voltage switch cabinet accessories are divided into two rows and fall on the conveyor belt 5. Moreover, since the side wall of the receiving hopper 2 is a hollow structure, the inner wall of the receiving hopper 2 is provided with a condensation cavity, the bottom side wall of the receiving hopper 2 is provided with a condensation inlet pipe 3, and the other side wall of the receiving hopper 2 is provided with a condensation outlet pipe 13.

[0037] Then, the high and low voltage switch cabinet accessories fall onto the conveyor belt 5 along the rectangular discharge port.

[0038] Since multiple groups of rollers 8 are arranged side by side between the active transmission shaft 7 and the driven transmission shaft 9, the rollers 8 are of a hollow structure and are provided with a heat dissipation cavity 17 inside, so that condensed water enters the diversion cavity 16 in the mounting frame 4 through the water inlet pipe 14, and enters another group of mounting frames 4 after passing through the heat dissipation cavity 17 in the rollers 8, and is discharged from the water outlet pipe 15 on the mounting frame 4 of the other group, so that the condensed water further cools the high and low voltage switch cabinet accessories being transported, thereby solving the problem in the prior art that after the casting process of the high and low voltage switch cabinet accessories is completed, the surface temperature of the high and low voltage switch accessories is high, and the accessories cannot be fed in time to complete the assembly of the high and low voltage switch cabinets. Instead, the high and low voltage switch cabinet accessories after casting need to be placed in a transfer box for cooling, and the cooling process takes a certain amount of time, thereby greatly reducing the efficiency of the processing and production of high and low voltage switch cabinet accessories.
