Description

Technical Field

[0001] This utility model belongs to the technical field of cutting and cutting equipment that moves along the cutting path, and in particular relates to a tool cooling device for cutting and cutting equipment that moves along the cutting path. Background Technology

[0002] Automatic cutting machines, also known as automatic cutting beds, are industrial automation equipment that achieves efficient and precise cutting through computer numerical control technology. They are adaptable to various materials such as clothing, leather, and fabrics, and have automatic layout and rapid cutting functions. They are widely used in clothing manufacturing, home textiles, automotive interiors, and industrial manufacturing.

[0003] Currently, when cutting equipment operates continuously, the cutting blades generate high temperatures due to high-speed friction, leading to a decrease in blade hardness, accelerated wear, and even material adhesion or rough cut surfaces. Therefore, it is necessary to cool the cutting blades. Existing cutting equipment generally uses air cooling to cool the cutting blades, relying solely on airflow to blow heat off the blade surface. Since the airflow cannot continuously cover the moving blade edge, and the contact time between the airflow and the high-temperature blade is short, the heat dissipation efficiency is low, which cannot effectively prevent the blade from continuously heating up, affecting the blade hardness and reducing the cutting effect.

[0004] To address these issues, we provide a blade cooling device for a cutting machine that operates while moving, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a tool cooling device for a cutting machine that moves along with the cutting process. By combining a contact cooling component and an airflow cooling component, this invention solves the problem in the prior art where the tool cooling device for a cutting machine that moves along with the cutting process relies solely on airflow, resulting in discontinuous heat dissipation, low cooling efficiency, and an inability to effectively suppress the continuous heating of the tool.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a blade cooling device for a cutting machine that operates while moving, comprising a fixed frame, a contact cooling assembly, and an airflow cooling assembly. A blade disc is fixedly connected to the bottom of the fixed frame, and a cutting blade is fixedly connected to the blade head at the top of the fixed frame. The bottom of the cutting blade extends through to the bottom of the blade disc. The contact cooling assembly includes a cooling shell, the bottom of which is movably connected to the blade disc via a telescopic rod. Electric push rods are fixedly connected to both sides of the inner cavity of the cooling shell. A conveying shell is fixedly connected to the output ends of the two electric push rods on opposite sides. The front sides of the two conveying shells are connected via a flexible hose. Heat-conducting plates are fixedly connected to the opposite sides of the two conveying shells. The airflow cooling assembly includes a cooling shell, the right side of which is fixedly connected to the cooling shell. A cooler is located at the bottom of the cooling shell, and the cooling end at the top of the cooler extends through to the inner cavity of the cooling shell. An air inlet is located on the left side of the cooling shell, and a fan is connected to the top of the cooling shell. The air outlet on the right side of the fan extends through to the inner cavity of the conveying shell.

[0008] The present invention is further configured such that an exhaust pipe is provided at the bottom of the cooling shell, an exhaust hole is provided on the surface of the exhaust pipe, the top of the exhaust pipe penetrates through the cooling shell and is connected to the conveying shell through a corrugated pipe, and the air circulating out of the conveying shell is discharged through the exhaust pipe and the exhaust hole to blow air to cool the surface of the cutting blade, thereby improving the cooling effect and using the fast-flowing airflow to remove excess heat.

[0009] The present invention is further configured such that both sides of the inner cavity of the conveying shell are fixedly connected to a sliding sleeve by a mounting bracket, and a sliding rod is slidably connected to the inner wall of the sliding sleeve. The opposite sides of the two sliding rods are fixedly connected to the conveying shell. The mounting bracket can increase the stability of the sliding sleeve installation and fixation.

[0010] The present invention is further provided that the top and bottom of the cooling shell are provided with movable openings for use with the cutting blade, and the surface of the cooling shell is provided with heat dissipation holes. The movable openings facilitate the cutting blade to move up and down quickly, so as to cut the raw material. The heat dissipation holes can increase the heat dissipation effect of the cooling shell, so that the internal heat can be quickly discharged.

[0011] The present invention is further configured such that guide rails are fixedly connected to both sides of the top of the inner cavity of the cooling shell, and linear bearings are slidably connected to the surface of the guide rails. The bottom of the linear bearings is fixedly connected to the conveying shell. The guide rails and linear bearings can increase the limiting effect on the conveying shell and prevent it from deviating during movement.

[0012] The present invention is further configured such that a heat dissipation fin is fixedly connected to the top of the cooler, and the opposite sides of the two heat-conducting fins both penetrate into the inner cavity of the conveying shell. The heat dissipation fins can increase the cooling effect of the cooler and increase the contact area between the air and its cold end. One side of the heat-conducting fin penetrates into the interior of the conveying shell to increase its contact area with the cold airflow.

[0013] The present invention is further configured such that the telescopic rod includes a base and a movable rod, the bottom of the base is fixedly connected to the cutter head, the surface of the movable rod is slidably connected to the inner wall of the base, and the top of the movable rod is fixedly connected to the cooling shell.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a contact cooling component and an electric push rod to drive the conveying shell so that the heat-conducting sheet actively contacts the cutting blade. The heat of the blade is directly conducted through physical contact, and the heat-conducting sheet exchanges heat with the circulating cold air in the conveying shell. This greatly improves the continuity of blade heat dissipation, solves the problem of low efficiency of air cooling and inability to effectively suppress the continuous temperature rise of the blade, and prevents the blade from becoming less hard or rough on the cutting surface due to overheating.

[0016] 2. This utility model uses an airflow cooling component to generate low-temperature airflow through a cooler, which is then injected into the conveying shell by a fan for circulation. This, combined with heat-conducting plates, efficiently cools the core area of ​​the cutting tool. At the same time, the circulated airflow is guided to the surface of the cutting tool through an exhaust pipe for auxiliary air cooling. This dual heat dissipation method enhances the overall cooling efficiency, suppresses the continuous heating of the cutting tool, and avoids the problem of uneven material cutting surfaces.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model relates to a blade cooling device for a cutting machine that operates while moving, comprising a fixed frame 1, a contact cooling assembly 4, and an airflow cooling assembly 5. A blade disc 2 is fixedly connected to the bottom of the fixed frame 1, and a cutting blade 3 is fixedly connected to the blade head at the top of the fixed frame 1. The bottom of the cutting blade 3 extends through to the bottom of the blade disc 2. The contact cooling assembly 4 includes a cooling shell 41, the bottom of which is movably connected to the blade disc 2 via a telescopic rod 42. Electric push rods 43 are fixedly connected to both sides of the inner cavity of the cooling shell 41, and the output ends of the two electric push rods 43 on opposite sides are fixedly connected to… The two conveyor shells 44 are connected by a hose 45 at their front sides. Heat-conducting plates 46 are fixedly connected to the opposite sides of the two conveyor shells 44. The airflow cooling assembly 5 includes a cooling shell 51. The right side of the cooling shell 51 is fixedly connected to the cooling shell 41. A cooler 52 is provided at the bottom of the cooling shell 51. The cooling end of the cooler 52 extends into the inner cavity of the cooling shell 51. An air inlet 53 is provided on the left side of the cooling shell 51. A fan 54 is connected to the top of the cooling shell 51. The air outlet on the right side of the fan 54 extends into the inner cavity of the conveyor shell 44.

[0027] Specifically: The cooling shell 41 facilitates the installation and fixation of the conveyor shell 44 and the electric push rod 43. The electric push rod 43 is used to control the position of the conveyor shell 44. When the cutting blade 3 performs up-and-down reciprocating cutting operations, the electric push rod 43 controls the movement of the two conveyor shells 44, so that the two heat-conducting plates 46 are in contact with the cutting blade 3. Then, the airflow cooling component 5 is used to reduce the temperature of the outside air. The low-temperature air continuously circulates inside the conveyor shell 44, and the heat-conducting plates 46 are used to cool the cutting blade 3, so that it is always kept at the normal working temperature and avoids the temperature from becoming too high. The outside air enters the cooling shell 51 through the air inlet 53, and its temperature is reduced by the cooler 52. Then, the fan 54 is used to transport the low-temperature air into the conveyor shell 44 to continuously carry out airflow cooling work, so as to prevent the cutting blade 3 from becoming high temperature during the cutting operation.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, the bottom of the cooling shell 51 is provided with an exhaust pipe 6, and the surface of the exhaust pipe 6 is provided with exhaust holes 7. The top of the exhaust pipe 6 passes through the cooling shell 41 and is connected to the conveying shell 44 through a corrugated pipe. Both sides of the inner cavity of the conveying shell 44 are fixedly connected to the sliding sleeves 8 by mounting brackets. The inner wall of the sliding sleeves 8 is slidably connected to the sliding rods 9. The opposite sides of the two sliding rods 9 are fixedly connected to the conveying shell 44. The top and bottom of the cooling shell 41 are provided with movable openings for use with the cutting blade 3. The surface is provided with heat dissipation holes. Guide rails are fixedly connected to both sides of the top of the inner cavity of the cooling shell 41. Linear bearings are slidably connected to the surface of the guide rails. The bottom of the linear bearings is fixedly connected to the conveying shell 44. Heat dissipation fins 10 are fixedly connected to the top of the cooler 52. The opposite sides of the two heat conduction fins 46 penetrate into the inner cavity of the conveying shell 44. The telescopic rod 42 includes a base and a movable rod. The bottom of the base is fixedly connected to the cutter disc 2. The surface of the movable rod is slidably connected to the inner wall of the base. The top of the movable rod is fixedly connected to the cooling shell 41.

[0030] Specifically: the air circulating from the conveyor housing 44 is discharged through the exhaust pipe 6 and exhaust hole 7, blowing air to cool the surface of the cutting blade 3, improving its cooling effect. The fast-flowing airflow carries away excess heat. The mounting bracket increases the stability of the sliding sleeve 8. The sliding sleeve 8 can cooperate with the sliding rod 9 to limit the two conveyor housings 44, allowing them to move smoothly left and right. The movable opening facilitates the rapid up and down reciprocating movement of the cutting blade 3, enabling it to cut the raw materials. The heat dissipation hole increases the heat dissipation effect of the cooling housing 41, allowing its internal heat to be quickly discharged. The guide rail and linear bearing increase the limiting effect of the conveyor housing 44, preventing it from shifting during movement. The heat dissipation fins 10 increase the cooling effect of the cooler 52, increasing the contact area between the air and its cold end. One side of the heat-conducting plate 46 extends into the interior of the conveyor housing 44, increasing its contact area with the cold airflow. The movable rod and the base cooperate to allow the cooling housing 41 to move up and down with the cutting blade 3.

[0031] The working principle of this utility model is as follows: When the cutting blade 3 performs the cutting operation, the electric push rod 43 is activated. The electric push rod 43 controls the movement of the two conveying shells 44, so that the heat-conducting plates 46 controlled by the two conveying shells 44 are in contact with the surface of the cutting blade 3. The height of the cooling shell 41 is adjusted synchronously by the telescopic rod 42 so that it always moves with the cutting blade 3. Heat is quickly transferred through direct contact with the heat-conducting plates 46. Subsequently, the cooler 52 works to generate a low-temperature environment. External air enters the cooling shell 51 through the air inlet 53 and is cooled by the cooler 52. After cooling, the fan 54 pumps cold air into the conveying shell 44. The cold airflow circulates within the conveying shell 44 and absorbs heat through the heat-conducting plate 46, greatly improving the continuity of heat dissipation of the cutting edge. This solves the problem of low air cooling efficiency and inability to effectively suppress the continuous heating of the cutting tool, preventing the cutting tool from becoming less hard or rough due to overheating. The circulated airflow is then guided through the corrugated pipe to the exhaust pipe 6, and then discharged from the exhaust hole 7 and blown onto the surface of the cutting blade 3, achieving secondary air cooling, suppressing the continuous heating of the cutting tool, and avoiding the problem of uneven material cutting surface.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
