Description

Technical Field

[0001] The utility model relates to the field of plastic product production, in particular to an automatic gate cutting device. Background Art

[0002] In the process of plastic injection molding, the plastic melt is injected into the mold through the nozzle of the injection molding machine, and after cooling and solidifying, a product is formed. The gate is the channel connecting the product and the nozzle of the injection molding machine, and usually needs to be removed after the product is formed to obtain a complete product. Manual gate cutting is easily affected by the operator's skill level, resulting in unstable product quality. The automatic gate cutting device can ensure the accuracy and consistency of each cutting, thus improving the product quality.

[0003] First, the plastic product is taken out of the mold. The sensors (such as photoelectric sensors, proximity sensors, etc.) of the automatic gate cutting device will detect the position of the product and transmit the information to the control system. According to the position information provided by the sensors, the control system commands the robotic arm to move the product to the cutting device. After the product reaches this position, the cutting device (such as scissors, blades, etc.) starts to work and cuts the gate from the product.

[0004] However, some gate cutting devices can cut too few gates at a time and cannot cut continuously, reducing the efficiency of gate cutting. In addition, after the gate is cut off, it cannot collect the gate, resulting in the gate being scattered on the workbench of the gate cutting device, affecting the subsequent processing or packaging process. Therefore, an automatic gate cutting device is proposed to solve the above problems. Summary of the Utility Model

[0008] As a further description of the above technical solution: the opposite ends of the two springs are fixedly connected to the opposite ends of the two moving grooves respectively, and the knobs are located at the outer ends of the fixing plates.

[0009] As a further description of the above technical solution: the moving blocks are all slidably connected to the moving grooves on the same side, and the internally threaded blocks and the externally threaded blocks are all slidably connected to the fixing plates on the same side.

[0010] As a further description of the above technical solution: the internally threaded blocks are engaged with the clamping grooves on the same side.

[0011] As a further description of the above technical solution: The picking and placing component includes a cylinder.

Since the opening of the guide groove is communicated with the top circumference, the cut gates will enter the interior of the collection box for collection. The collected gates can be reused, saving resources. Description of the Drawings

[0024] First, fix the top perimeter 26 through the fixed component, so that the top opening of the top perimeter 26 is aligned with the bottom of the guide groove 17, which is convenient for collecting the gates sheared by the scissors 16. By starting the motor 5, the turntable 4 can be driven to rotate, thereby driving the four picking and placing components at the bottom of the turntable 4 to rotate, so as to realize the continuous gate-cutting operation and improve the gate-cutting efficiency.

[0025] Refer to Figure 2 andFigure 3 , both fixed components include a fixed plate 18, the top ends of the fixed plates 18 are fixedly connected to the bottom of the workbench 14, movable slots 19 are provided in the middle of the fixed plates 18, moving blocks 20 are arranged at opposite ends of the movable slots 19, external threaded blocks 21 are rotatably connected to the middle parts of the moving blocks 20, internal threaded blocks 22 are threadedly connected to opposite ends of the external threaded blocks 21, knobs 24 are fixedly connected to opposite ends of the external threaded blocks 21 away from each other, springs 23 are fixedly connected to opposite ends of the moving blocks 20 away from each other outside the external threaded blocks 21, opposite ends of the two springs 23 are respectively fixedly connected to opposite ends of the movable slots 19, the knobs 24 are located at the outer ends of the fixed plates 18, the moving blocks 20 are all slidably connected to the same-side movable slots 19, the internal threaded blocks 22 and the external threaded blocks 21 are all slidably connected to the same-side fixed plates 18, and the internal threaded blocks 22 are snap-fitted with the same-side card slots 27.

[0026] By aligning the card slot 27 with the same-side internal threaded block 22, the spring 23 drives the moving block 20 to move towards the same-side card slot 27, and then the same-side knob 24 is rotated to make the external threaded block 21 drive the internal threaded block 22 to be snap-fitted with the card slot 27. At this time, the top of the top perimeter 26 is located directly below the guiding slot 17, which is convenient for collecting the gate cut by the scissors 16.

[0027] Refer to Figure 1 and Figure 4 , the picking and placing component includes a cylinder 7, the input end of the cylinder 7 is fixedly connected to the bottom end of the turntable 4, the output end of the cylinder 7 is fixedly connected to a connecting block 8, four suction components 13 are fixedly connected to the bottom end of the connecting block 8 at equal distances, a placement slot 9 is provided inside the connecting block 8, a vacuum pump 10 is fixedly connected to the top end of the connecting block 8 on one side outside the cylinder 7, the output end of the vacuum pump 10 is fixedly connected to a main pipe 11, the end of the main pipe 11 is fixedly connected to the middle of the bottom end of the placement slot 9, four branch pipes 12 are fixedly connected to the outside of the bottom end of the main pipe 11 at equal distances, and the ends of the four branch pipes 12 are all communicated with the top ends of the same-side adjacent suction components 13.

[0028] By starting the cylinder 7, the connecting block 8 is driven to move downward, so that the bottom of the suction component 13 is attached to the top of the plastic product placed on the conveyor belt. Then, the vacuum pump 10 is started, so that the branch pipes 12 and the main pipe 11 suck out the air inside the adjacent suction components 13, thereby enabling the suction components 13 to adsorb the plastic product. Then, the cylinder 7 is started to drive the connecting block 8 to rise. By starting the vacuum pump 10, the main pipe 11 sucks the external air into the suction component 13, which can enable the suction component 13 to unload the plastic product.

[0029] Working principle: First, start the cylinder 7 on the right side and the vacuum pump 10, so that the four suction parts 13 on the right side adsorb the plastic products arranged on the conveyor belt. Then, the cylinder 7 drives the connecting block 8 to rise, start the motor 5, and make the turntable 4 rotate. When the position of the suction part 13 on the adsorbed plastic product corresponds to the position of the scissors 16 on the workbench 14, start the cylinder 7 to drive the connecting block 8 to move downwards, so that the four scissors 16 can accurately cut off the gates on the corresponding plastic products. The cut-off gates slide into the interior of the collection box 25 through the guide groove 17 for collection. When the cutting of the plastic product gates on the connecting block 8 is completed, start the motor 5 again to move the connecting block 8 to the rear side, and then place the plastic products with the gates cut off at the collection place, and the cutting of the plastic product gates can be carried out continuously.
