Description

Technical Field

[0001] This utility model relates to the field of automated cutting technology, and in particular to an electrical automation device for cutting. Background Technology

[0002] The function of automated cutting equipment is to achieve semi-automated or fully automated cutting operations on various materials (such as metals, acrylic, etc.) through the coordination of mechanical structure and electronic control system. Its main structure usually includes a power system, a cutting actuator, such as a cutting blade that directly acts on the material to complete the cutting, positioning (guide rail slide, clamping block), and an electronic control system, such as a PLC controller, sensors, and human-machine interface, which receives signals and controls the coordinated operation of various components.

[0003] Existing cutting devices suffer from the following common problems when cutting acrylic materials: The acrylic material, heated by the cutting blade, melts and adheres to the cutting disc, resulting in an uneven cut surface and even blade jamming. Currently, most devices use an anti-adhesion coating on the outer surface of the cutting blade; however, this coating often wears down significantly after only 10-20 uses, causing the melted acrylic material to still adhere to the cutting disc. Furthermore, the wear and tear from the coating can exacerbate blade jamming. Therefore, we propose an electrically automated cutting device to address these problems encountered in existing technologies. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0027] Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides an electrical automation device for cutting, including a workbench 1 and a PLC controller 2. A cutting blade 3 and a clamping block 8 are movably arranged on the upper end of the workbench 1. A stop block 9 is fixed on the upper end of the workbench 1. Heat-conducting components 4 are arranged on the front and rear sides of the cutting blade 3. The heat-conducting components 4 include a scraper 41 and steel balls 42. The aluminum scraper 41 is located on the front and rear sides of the cutting blade 3. The steel balls 42 are rotatably arranged on the side of the scraper 41 for rolling with the outer surface of the cutting blade 3.

[0028] Steel balls 42 are used to dissipate heat during the rotation of the cutting blade 3.

[0029] A cooling plate 43 and an axial fan 44 are provided on one side of the scraper 41;

[0030] The axial fan 44 is activated to maintain the low temperature of the cooler 43 and increase heat dissipation. It should be noted that the core material of the cooler 43 is a P-type and N-type semiconductor thermoelectric material based on bismuth telluride (Bi2Te3). The axial fan 44 accelerates the airflow around the heat-dissipating end, quickly removing the heat from the heat-dissipating end and preventing heat accumulation. This ensures that the cooling end of the cooler 43 can continuously and stably absorb heat, maintain a low temperature, and ultimately achieve the effect of cooling the scraper 41 and the cutting blade 3.

[0031] At a normal room temperature of 20-25℃, when the axial fan 44 dissipates heat from the heat-dissipating end of the cooling plate 43, the cutting blade 3 can be cooled to 5-15℃. If the ambient temperature is low, such as around 15℃, the temperature of the cutting blade 3 can be further reduced to -5 to 5℃. This temperature range can prevent the acrylic from melting and sticking due to the high temperature of the cutting blade, and also prevent the cutting blade 3 from condensing or affecting the stability of equipment operation due to excessively low temperature.

[0032] The thermoelectric cooler 43 typically has two pins, a positive and a negative terminal, which must be correctly connected to the DC power supply when powered on. The red wire of the thermoelectric cooler 43 is connected to the positive terminal of the power supply, and the black wire is connected to the negative terminal. Before powering on, ensure that the voltage and current of the power supply meet the specifications of the thermoelectric cooler. This is a common TEC1-12706 thermoelectric cooler, whose operating voltage is typically 12V and whose maximum current can reach 6A. Therefore, a suitable 12V DC power supply must be selected. This power supply method is existing technology and will not be described in detail. Example 2

[0033] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, Figure 1 In the middle, the upper surface of the workbench 1 is fixed with a stop block 9 by bolts. The stop block 9 is L-shaped. The top wall of the stop block 9 and the upper surface of the workbench 1 are both fixed with a second electric telescopic rod 7, and the output ends of the two second electric telescopic rods 7 are fixed with a clamping block 8 by bolts to fix the cutting parts.

[0035] The second electric telescopic rod 7 pushes the clamping block 8 to apply pressure from both sides of the cylindrical acrylic above, and the L-shaped stop block 9 fixes the cutting part in multiple directions to prevent the material from shifting during cutting.

[0036] Specifically, Figure 1 In the middle, the upper end of the workbench 1 is fixed with an electric slide rail 5 by a fixed seat, and the output end of the electric slide rail 5 is fixed with an electric telescopic rod 6.

[0037] The electric slide rail 5 drives the first electric telescopic rod 6 to move back and forth, adjusting the relative position of the cutting blade 3 and the cylindrical acrylic, thus providing a basis for position adjustment for cutting.

[0038] Specifically, Figure 1 and Figure 3 In the middle, the output end of the No. 1 electric telescopic rod 6 is fixed with a servo motor 10 through a bracket, and the output end of the servo motor 10 is fixed with a cutting blade 3 through a connecting shaft to drive the cutting blade 3 to rotate;

[0039] The servo motor 10 drives the cutting blade 3 to rotate at high speed, while the first electric telescopic rod 6 pushes the cutting blade 3 closer to and into contact with the material to achieve the cutting action.

[0040] Specifically, Figure 3 In the middle, two connecting brackets 48 are welded to the output end of the No. 1 electric telescopic pole 6, and one end of each connecting bracket 48 is fixed to the scraper 41 by bolts;

[0041] By fixing the scraper 41 close to the cutting blade 3, it is ensured that the scraper 41 can fit against the front and back sides of the cutting blade 3 during cutting. It should be noted that the distance between the inner wall of the two scrapers 41 and the front and back sides of the cutting blade 3 is 1mm. If it is greater than 1mm, it cannot scrape off, and if it is less than 1mm, it is easy to cause the cutting blade 3 to jam. Example 3

[0042] Reference Figure 2 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, Figure 2 In the middle, a bullseye bearing 47 is fixed to the right side of the scraper 41 by bolts. A steel ball 42 is installed inside the bullseye bearing 47, and the outer surface of the steel ball 42 abuts against the front and rear sides of the cutting blade 3.

[0044] The steel balls 42 reduce the friction between the scraper 41 and the cutting blade 3, ensuring the smooth rotation of the cutting blade 3. At the same time, the rolling of the steel balls 42 transfers the heat of the cutting blade 3 to assist in heat dissipation.

[0045] Specifically, Figure 2 In the middle, the scraper 41 is hollow;

[0046] The hollow design also reduces the weight of the scraper 41, lowers the load on the connecting frame 48, and enhances heat dissipation.

[0047] Specifically, Figure 2 In the middle, the front side of the scraper 41 is fixed with rivets to the cooling plate 43, and the front side of the cooling plate 43 is fixed with bolts to the axial fan 44;

[0048] The cooling plate 43 cools the scraper 41 and the cutting blade 3, and the axial fan 44 accelerates the airflow around the cooling plate 43 to enhance the heat dissipation effect and prevent the scraper 41 from heating up and causing the residual particles to stick together again.

[0049] Specifically, Figure 2 In the middle, at least four heat sinks 45 are integrally provided on the left side of each scraper 41; each heat sink 45 is provided with a through hole 46;

[0050] Each scraper 41 has at least four aluminum heat sinks 45 integrated on its left side with built-in through holes 46. The purpose of these heat sinks is to increase the heat dissipation area, improve the overall heat dissipation efficiency, ensure that the cutting blade 3 is at a suitable temperature, and reduce the melting and sticking of acrylic due to the heat generated by the cutting blade.

[0051] Working principle: PLC controller 2, as the core control unit, first receives the preset cutting parameters. After starting, it controls the extension of the second electric telescopic rod 7, pushing the two clamping blocks 8 to apply pressure from the top of both sides of the cylindrical acrylic material. Together with the L-shaped stop block 9 fixed on the worktable 1, the cylindrical acrylic material is firmly fixed from multiple directions to avoid material displacement during cutting and affect cutting accuracy.

[0052] Next, the electric slide rail 5 is controlled to drive the first electric telescopic rod 6 at its output end, which pushes the cutting blade 3, which is driven by the servo motor 10 to rotate at high speed, to approach and contact the cylindrical acrylic material, thereby realizing the cutting operation of the cylindrical acrylic material.

[0053] During the cutting process, the scraper 41, which is fixed to the output end of the No. 1 electric telescopic rod 6 through the connecting frame 48, always keeps in contact with the front and rear sides of the cutting blade 3, scraping away residual particles on the surface of the cutting blade 3 caused by the melting of acrylic due to heat in real time, preventing the accumulation of particles from causing the cutting surface to be rough.

[0054] Meanwhile, the steel ball 42 in the bullseye bearing 47 on the right side of the scraper 41 keeps in rolling contact with the outer surface of the cutting blade 3, ensuring that the cutting blade 3 rotates smoothly while transferring the heat generated by the cutting blade 3 through the rolling of the steel ball 42, thus assisting the cutting blade 3 in dissipating heat.

[0055] In addition, the axial fan 44 on the front side of the scraper 41 accelerates the airflow around the cooling plate 43, enhances the heat dissipation effect, and makes the cooling plate 43 work continuously to cool the scraper 41 and the cutting blade 3, so as to prevent the scraper 41 from heating up due to absorbing cutting heat, which would cause the scraped residual particles to stick to the scraper 41 or the cutting blade 3 again.

[0056] The heat sink 45 and the through hole 46 integrated on the left side of the scraper 41 further expand the heat dissipation area and improve the overall heat dissipation efficiency, ensuring that the cutting blade 3 is always at a suitable temperature, and reducing the possibility of acrylic melting and sticking due to the heat generated by the cutting blade 3.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
