Description

Technical Field

[0001] This utility model relates to the technical field of grinding machine equipment, specifically a grinding machine protection device. Background Technology

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are applied to any part of the human body surface, such as skin, hair, nails, lips, and teeth, by means of smearing, spraying, or other similar methods, to achieve the purpose of cleaning, maintaining, beautifying, modifying and altering appearance, or correcting body odor and maintaining a good condition.

[0003] Three-roll mills are commonly used equipment in cosmetic processing. They achieve the grinding effect by pressing the surfaces of three horizontal rollers against each other and rubbing at different speeds. They are the most effective grinding and dispersing equipment for high-viscosity materials.

[0004] Three-roll mills are extremely dangerous equipment, prone to accidents that can lead to serious injuries. To reduce the risk of injury, a safety line (such as a safety line) is installed above the three-roll mill. Figure 1 As shown, when a person touches the safety line, the sensor will be triggered, which will then alarm or shut down the equipment. This method can reduce safety hazards, but the detection range is small and the sensitivity is low.

[0005] In view of this, there is an urgent need for a grinding machine protection device to overcome the shortcomings of the existing technology. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A grinding machine protection device includes: a support frame, a protection device, and a sensor. The protection frame includes a detection rod and two detection frames. The detection rod is horizontally mounted on the support frame, and the two detection frames are mounted on the detection rod. The detection frames extend downward at an angle from one side of the detection rod, and the two detection frames are symmetrically arranged with respect to a vertical plane.

[0009] The sensor is used to detect the activity state of the detection rod.

[0010] The testing frame is U-shaped, and both ends of the testing frame are connected to the testing rod.

[0011] The downward angle between the two testing frames is between 40 and 150 degrees.

[0012] The downward angle between the two testing frames is between 90 and 110 degrees.

[0013] The downward angle between the two testing frames is 90 degrees.

[0014] Two support frames are provided, and the two ends of the detection rod are respectively rotatably mounted on the two support frames.

[0015] A U-shaped detection plate is provided at one end of the detection rod. The opening direction of the detection plate is perpendicular to the axis of the detection rod, and the detection end axis of the sensor passes through the opening of the detection plate.

[0016] The opening of the detection plate faces directly downwards.

[0017] The sensor is an infrared sensor.

[0018] The testing frame is fixed to the testing rod by welding.

[0019] The above-described structure of this utility model can achieve the following beneficial effects:

[0020] In use, the protective frame is set above the three-roll mill using a support frame. The two detection frames are balanced by gravity, and the area within the two detection frames is the protection zone. If an operator accidentally enters the protection zone with their arm or other part of their body, they will touch the detection frame, disrupting the balance of the two detection frames and causing the detection rod to rotate. At this time, the sensor detects the movement of the detection rod, issuing an alarm or stopping the equipment, thus protecting the operator and reducing safety hazards. Furthermore, the symmetrical arrangement of the two detection frames expands the monitoring range, provides high sensitivity, and has a low manufacturing cost. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0028] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0029] refer to Figure 2 and Figure 3 The grinding machine protection device shown includes: a support frame 1, a protection device and a sensor 2. The protection frame includes a detection rod 3 and two detection frames 4. The detection rod 3 is horizontally arranged on the support frame 1, and the two detection frames 4 are both arranged on the detection rod 3. The detection frames 4 extend downward at an angle from one side of the detection rod 3, and the two detection frames 4 are symmetrically arranged with respect to the vertical plane.

[0030] Based on the above structure, during use, the protective frame is set above the three-roll mill via the support frame 1. The two detection frames 4 are balanced by gravity, and the area where the two detection frames 4 are located is the protection range. When personnel operate, if their arms or other parts accidentally enter the protection range, they will touch the detection frames 4, disrupting the balance of the two detection frames 4 and causing the detection rod 3 to rotate. At this time, the sensor 2 detects the movement of the detection rod 3 and issues an alarm or stops the equipment through the corresponding device to protect the personnel and reduce safety hazards.

[0031] like Figures 2-4 As shown, in order to expand the protection range, the detection frame 4 is U-shaped, and both ends of the detection frame 4 are connected to the detection rod 3. In this way, the two U-shaped detection frames 4 extend inclined to both sides, thereby expanding the monitoring range and improving the protection effect. The downward angle between the two detection frames 4 can be 40 degrees to 150 degrees (e.g., 40 degrees, 60 degrees, 90 degrees, 120 degrees or 150 degrees), and the optimal angle is 90 degrees to 110 degrees (e.g., 90 degrees, 100 degrees or 110 degrees). In this embodiment, the angle is set to 90 degrees.

[0032] like Figure 2 As shown, in order to improve the stability of the support, there are two support frames 1. The two ends of the detection rod 3 are respectively rotatably mounted on the two support frames 1 to support the detection rod 3 from both sides.

[0033] like Figure 3 As shown, in order to monitor the movement of the detection rod 3, a U-shaped detection plate 5 is provided at one end of the detection rod 3. The opening direction of the detection plate 5 is perpendicular to the axis of the detection rod 3. The detection end axis of the sensor 2 (the sensor 2 can be an infrared sensor, etc.) passes through the opening of the detection plate 5. The optimal orientation of the opening of the detection plate 5 is directly downward. That is to say, under normal conditions, the sensor 2 will not detect the two sides of the opening of the detection plate 5 (the detection plate 5 is not within the detection range of the sensor 2). When the detection rod 3 rotates, the detection plate 5 rotates accordingly, so that one side of the opening of the detection plate 5 moves into the detection range of the sensor 2, thereby realizing monitoring, playing a protective role, and having high sensitivity.

[0034] A further optimization is that the detection frame 4 and the detection rod 3 can be made of stainless steel tubing, and the detection frame 4 is fixed to the detection rod 3 by welding. This gives the present application a longer service life and makes it easier to process.

[0035] In summary, during use, the protective frame is placed above the three-roll mill using the support frame 1. The two detection frames 4 are balanced by gravity, and the area where the two detection frames 4 are located is the protection range. If an operator accidentally enters the protection range with their arm or other part, they will touch the detection frame 4, disrupting the balance of the two detection frames 4 and causing the detection rod 3 to rotate. At this time, the sensor 2 detects the movement of the detection rod 3, issuing an alarm or stopping the equipment, thus protecting the operator and reducing safety hazards. Furthermore, the symmetrical arrangement of the two detection frames 4 expands the monitoring range, provides high sensitivity, and has a low manufacturing cost.

[0036] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
