Description

Technical Field

[0001] This utility model belongs to the field of cutting machines, and in particular relates to a waterjet cutting device. Background Technology

[0002] Waterjet cutting machines use a high-pressure pump to pressurize ordinary water into high-pressure water, which is then delivered through pipes to the waterjet cutting head. The water jet from the head acts on the material being cut, thus completing the cut. Waterjet cutting can process materials that are difficult or impossible to process using traditional or other methods, such as stone, glass, ceramics, cemented carbide, diamond, and carbon fiber composites. Furthermore, it can perform not only straight cuts but also curved cuts, bevel cuts, and other cutting methods, meeting diverse processing needs.

[0003] Currently, to achieve different cutting shapes, 3D scanning technology can be used in conjunction with waterjet cutting. The data provided by 3D scanning technology can be used to support the waterjet cutting path, such as the method for measuring the length and radius of ultra-high pressure water jets used in waterjet cutting disclosed in existing patent CN201010153616.4. However, most waterjet cutting equipment is equipped with a 3D scanning camera and a waterjet cutting machine, so the cut products are relatively simple. Some materials whose own margin does not meet the corresponding cutting shape requirements will be classified as defective products. However, these defective materials can actually be processed into products of other shapes. Therefore, existing equipment is not conducive to making full use of materials and increasing production costs. Furthermore, the sorting steps involved after the product is output from the cutting machine will be completed separately in the next set of equipment, which will also increase production costs to some extent. In addition, existing waterjet cutting machines are mostly used in the metal cutting industry. If applied to the food industry production line, new requirements will be placed on the waterjet cutting machine. Utility Model Content

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Examples, such as Figures 1-4 As shown, the waterjet cutting equipment provided by this utility model includes a scanning station 1 and a cutting station 2. The scanning station 1 is equipped with two sets of 3D scanning cameras 21 distributed along the material conveying direction. The cutting station 2 is equipped with four sets of waterjet cutting machines 31 distributed along the material conveying direction. A feeding station 1 is provided on the feeding side of the scanning station 1, and a grading station 5 is provided on the discharging side of the cutting station 2. A stainless steel mesh belt conveyor 4 is provided on the inner side of the scanning station 1 and the cutting station 2, which is connected to the feeding station 1 and the grading station 5. The grading station 5 includes a chain plate conveyor 51. Multiple pairs of material-removing robotic arms 52 distributed along the material conveying direction are provided on both sides of the chain plate conveyor 51. A material drop hopper 53 is provided below the material-removing robotic arms 52.

[0016] Specifically, the machine provided by this utility model is a two-channel design. Two relatively independent 3D scanning cameras 21 collect product image data for their respective channels and send it to a computer. The computer system in the workshop where this equipment is located can collect scanning data, plan cutting paths, and control the operation of the entire machine. The images captured by the 3D scanning cameras 21 are used as the cutting basis for the cutting station 2. Furthermore, each channel of this equipment is equipped with two waterjet cutting machines 31, each with a high-pressure waterjet cutting head 312 at its end, connected to a high-pressure water pipe 313. A motion controller controls their movements to complete different shape cutting requirements. That is, every two waterjet cutting machines 31 correspond to one 3D scanning camera 21, with a total of four waterjet cutting machines 31 engaged in cutting operations. This improves the equipment's cutting capability and can meet multiple different cutting requirements. By setting a grading station 5 on the output side of the cutting station 2, product grading can be achieved without transferring products to the next workshop for grading, thus shortening the production line length. This utility model has a reasonable design, simple structure, good processing capacity, product screening capability, and can meet the requirements of food processing workshops, with a high utilization rate.

[0017] To recycle the wastewater and waste residue generated at the cutting station 2, this invention provides a wastewater collection hopper 6 inside the stainless steel mesh belt conveyor 4, which corresponds vertically to the cutting station 2. The wastewater collection hopper 6 corresponds to the upper part of the stainless steel mesh belt conveyor 4. The wastewater generated during cutting falls from the upper part of the stainless steel mesh into the wastewater collection hopper 6. The wastewater collection hopper 6 is tilted towards the rear of the entire machine for easy centralized discharge. Furthermore, a waste residue collection hopper 7 is provided below the stainless steel mesh belt conveyor 4 near its conveying end. The waste residue from the conveying surface of the stainless steel mesh belt conveyor 4 falls into the waste residue collection hopper 7, which centrally discharges the waste residue.

[0018] Furthermore, the waterjet cutting machine 31 provided by this utility model includes a cutting robotic arm 311, which is a two-axis robot. The execution end of the cutting robotic arm 311 is equipped with a waterjet cutting head 312, and a high-pressure water pipe 313 is provided on the waterjet cutting head 312. The supply end of the high-pressure water pipe 313 is equipped with a high-pressure water pump and a valve (not shown in the figure). The terminal of the waterjet cutting machine 31 controls the opening and closing of the waterjet cutting head 312 through electricity / pneumatic control. The two-axis robot is used to control the real-time working position of the waterjet cutting head 312. By changing the position, different processing curves are obtained, thereby meeting the product shape requirements under different waterjet cutting heads 312, so as to correspond to the grading standards of the subsequent grading station 5.

[0019] To improve the utilization rate of this equipment, the high-pressure water pump provided by this utility model is a food-grade booster pump. The food-grade booster pump has excellent sealing performance, which can prevent material leakage or the mixing of external impurities, avoid cross-contamination between different batches and different types of food, and especially ensure the hygiene of food products, which is conducive to ensuring the safety of food products. Furthermore, the food-grade booster pump used in this utility model can reach a maximum pressure of 413 MPa, which, together with the water softening equipment, ensures food hygiene.

[0020] To improve the grading effect of the grading station 5, the grading station 5 provided by this utility model includes a middle partition plate 54 distributed near the middle position of the chain conveyor 51. A gate-shaped mounting frame 55 is provided on the top of the middle partition plate 54, and the mounting frame 55 is connected to the body of the chain conveyor 51. Materials fed to the feeding station 1 can be distributed in a staggered manner, passing orderly through the stainless steel mesh belt conveyor 4. Upon entering the chain conveyor 51, the middle partition plate 54 further ensures the left-right distribution of the materials, which helps to ensure the accuracy of material removal by the material-removing robotic arms 52 distributed in different positions.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
