Technical Field

[0001] The utility model relates to the field of blade detection, in particular to a blade detection device. Background Art

[0002] A kitchen blender is a household blending and crushing device, which mainly uses a blending blade to blend and crush food. It can blend meat, or blend some fruits and vegetables for making fruit juice or vegetable juice. When in use, the food is placed in the kitchen blender, and the motor drives the blending blade to rotate at high speed. The blending blade blends and crushes the food during the rotation. In order to ensure the crushing effect of the blending blade, a blade will be polished on one side of the blending blade, and the sharpness of the blade will be tested at the same time. The existing blade sharpness test is generally performed by the tester using the blade to scratch the test object to test the sharpness.

[0003] According to the search, a Chinese patent with application number 202321899379.5 discloses a stirring blade sharpness detection device, which regulates the detection by installing a motor to control the feed speed, cutting speed, feed depth and cutting depth. However, scratches will be left on the detected object after the detection, and the scratches are embedded in the detected object, which is not easy to measure and observe, and there will be deviations only through manual observation. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a blade detection device to solve the technical problem that scratches are embedded in the detection object, are not easy to measure and observe, and there are deviations only through manual observation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blade detection device, comprising two detection components that can move toward each other, the detection components comprising a first detection chamber and a second detection chamber that can interchange positions, a detection object is fixed on the first detection chamber, the detection object is used to produce scratches under the action of the blade assembly, and a deformable block is fixed on the second detection chamber, wherein the deformable block in the second detection chamber on one side produces a protruding mark when it approaches the detection object in the first detection chamber on the other side and contacts and squeezes the scratch thereon, and the protruding mark completely matches the scratch.

[0006] By adopting the above technical solution, the sharpness of the blade can be tested and the test results can be verified respectively, thereby improving the accuracy and reliability of the test. The combination of the scratches on the test object and the protrusions on the deformable block makes the test results more intuitive and convenient for measurement and observation.

[0007] Furthermore, the blade detection device also includes a base, and the two detection components are movably arranged on the base and arranged opposite to each other. A cavity is opened inside the base, and a bidirectional screw rod is arranged in the cavity. Two oppositely arranged screw rod sleeves are installed on the bidirectional screw rod, and the detection component is rotatably connected to the screw rod sleeve.

[0008] By adopting the above technical solution, the cavity can effectively utilize the space, provide installation positions for the bidirectional screw and other components, make the device structure more compact, and the bidirectional screw can realize motion control in two directions, so that the relative position between the two detection components can be easily adjusted, making the operation more flexible. At the same time, the detection component is rotatably installed on the screw sleeve, and the two first detection chambers are relatively fixed during detection. When the convex mark is printed, the detection component can be rotated in the opposite direction, so that the second detection chamber in the detection component on one side is opposite to the first detection chamber in the detection component on the other side, and the deformable block is brought close to the detection object and contacts the extrusion scratch through the bidirectional screw, thereby generating a convex mark.

[0009] Furthermore, the bidirectional screw rod passes through the outer end of the base and is connected to a turntable.

[0010] By adopting the above technical solution, the turntable connected to the outer end is used to operate the bidirectional lead screw, which saves time and effort. The staff can control the movement of the lead screw by rotating the turntable without directly contacting the lead screw, thereby improving the convenience of operation.

[0011] Furthermore, a limiting groove is provided on the top of the base, and the limiting groove is used to limit the sliding of the screw sleeve.

[0012] By adopting the above technical solution, the limit groove provides a fixed sliding path for the screw sleeve, ensuring the linearity and stability of the detection component on the screw sleeve when moving, and maintaining the correct position and direction of the detection component.

[0013] Furthermore, a second screw is threaded through the top of each of the first detection chamber and the second detection chamber, a knob is fixed to the top of the second screw, a pressure plate is rotatably connected to the bottom of the knob, and the first detection chamber and the second detection chamber are separated by a vertical plate.

[0014] By adopting the above technical solution, fine adjustment of the position of the pressure plate can be achieved. The design of the knob makes the operation more convenient. The staff can easily rotate the knob by hand without using tools, which improves the operating efficiency.

[0015] Furthermore, the deformable block is rubber clay.

[0016] By adopting the above technical solution, since rubber clay, as the material of the deformable block, has good flexibility and plasticity, the impact of the blade on the test object can be accurately recorded on the rubber clay during the detection process, ensuring the accuracy and reliability of the detection results.

[0017] Furthermore, the blade assembly includes a cylinder, an adjusting arm, a motor, a rotating shaft, a first screw, and a blade. The cylinder is fixedly connected to the base, the output end of the cylinder is equipped with the laterally arranged adjusting arm, the end of the adjusting arm is equipped with the motor, the output end of the motor is connected to the rotating shaft, the end of the rotating shaft is fixed with the first screw, and the end of the first screw is fixed with the blade.

[0018] By adopting the above technical solution, the cylinder provides precise force output and can accurately control the height of the adjustment arm, thereby ensuring the correct position of the motor and the rotating shaft, being able to adapt to blades of different sizes and shapes, and improving the versatility of the device.

[0019] To sum up, the utility model mainly has the following beneficial effects: by setting up two groups of detection chambers, each group of detection chambers includes a first detection chamber and a second detection chamber, the first detection chamber fixes the detection object, and the second detection chamber fixes the deformable block. After the sharpness detection of the blade is completed, the blade will leave scratches on the detection object. At this time, the staff rotates one group of detection components, matches the deformable block with the detection object of the other group, and then rotates the turntable to squeeze the deformable block with the detection object, thereby printing a convex mark on the deformable block. The convex mark protrudes from the deformable block, which is beneficial for the staff to measure with a ruler or scale. The measurement data is accurate and intuitive, which avoids errors in staff observation and is beneficial for use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] Embodiment 1:

[0029] A blade detection device, such as Figure 2-Figure 4 As shown, it includes a detection assembly 6 and a blade assembly on the left and right sides, and the detection assembly 6 includes a first detection chamber 61 and a second detection chamber 63. A detection object 64 is fixed on the first detection chamber 61. When the sharpness of the blade assembly is detected, the two detection objects 64 on the left and right sides are arranged face to face. When the blade assembly is in action, scratches 641 will be generated on the two detection objects 64. A deformable block 65 is fixed on the second detection chamber 63. When the detection result is verified, the positions of the first detection chamber 61 and the second detection chamber 63 on one of the detection assemblies 6 are swapped. For example, the deformable block 65 on the left is arranged face to face with the detection object 64 on the right. When the deformable block 65 on the left contacts and squeezes the detection object 64 on the right, a protruding mark 651 that completely matches the scratch 641 will be generated on the deformable block 65 on the left. The protruding mark 651 is printed on the deformable block 65, and the staff can use a ruler or a scale to accurately measure the protruding mark 651, which reduces the error of subjective judgment and improves the accuracy of the measurement data.

[0030] See also Figure 1The blade detection device also includes a base 1, two detection components 6 are movably arranged on the base and arranged oppositely, a cavity is opened inside the base 1, a bidirectional screw rod 5 is arranged in the cavity, two oppositely arranged screw rod sleeves 51 are installed on the bidirectional screw rod 5, and the detection component 6 is rotatably arranged on the screw rod sleeve 51. The cavity can effectively utilize the space, provide installation positions for the bidirectional screw rod 5 and other components, and make the device structure more compact. The bidirectional screw rod 5 can realize the motion control of the detection component 6 in two directions, so that the position of the detection component 6 can be easily adjusted, making the operation more flexible. The two oppositely arranged screw rod sleeves 51 can ensure the symmetry of the detection component 6 and ensure the stability and balance during the detection process.

[0031] See also Figure 1 The bidirectional screw rod 5 passes through the base 1 and is connected to a turntable 52 at the outer end. The turntable 52 connected to the outer end is used to operate the bidirectional screw rod 5, which saves time and effort. The staff can control the movement of the bidirectional screw rod 5 by rotating the turntable 52 without directly contacting the bidirectional screw rod 5, which improves the convenience of operation. The design of the bidirectional screw rod 5 passing through the base 1 makes the movement of the bidirectional screw rod 5 more stable, because it can be supported in the cavity of the entire base 1, which helps to evenly distribute the force and reduce wear or deformation caused by excessive local force.

[0032] See also Figure 2 The tops of the first detection chamber 61 and the second detection chamber 63 are both threaded with a second screw 68, the top of the second screw 68 is fixed with a knob 67, the bottom of the knob 67 is rotatably connected to a pressure plate 66, the first detection chamber 61 and the second detection chamber 63 are separated by a vertical plate 62, and the position of the pressure plate 66 can be finely adjusted. The design of the knob 67 makes the operation more convenient, and the staff can easily rotate the knob 67 by hand without using tools, thereby improving the operating efficiency.

[0033] Embodiment 2:

[0034] See also Figure 1 A limiting groove 11 is provided on the top of the base 1. The limiting groove 11 provides a fixed sliding path for the screw sleeve 51, so that the screw sleeve 51 can slide in a limited position, ensuring the linearity and stability of the detection component 6 when moving, and preventing the detection component 6 from being offset or twisted during operation, thereby maintaining the correct position and direction of the detection component 6. The limiting groove 11 guides the screw sleeve 51, making the screw sleeve 51 smoother when sliding, reducing the risk of wear and damage caused by friction or misalignment. The staff can easily position the screw sleeve 51 to the desired position without the need for additional tools or complicated adjustment steps, thereby simplifying the operation process.

[0035] See also Figure 2 and Figure 5The deformable block 65 is made of rubber clay. Rubber clay is used as the material of the deformable block 65. Since rubber clay has good flexibility and plasticity, the influence of the blade assembly on the test object 64 during the detection process can be accurately and clearly recorded on the deformable block 65, which is convenient for staff to observe and measure, reduces errors caused by inaccurate observation, and ensures the accuracy and reliability of the test results.

[0036] See also Figure 1 The blade assembly includes a cylinder 2, an adjusting arm 3, a motor 4, a rotating shaft, a first screw 41, and a blade. The cylinder 2 is vertically installed on one side of the top of the base 1. The output end of the cylinder 2 is installed with a horizontally arranged adjusting arm 3. The end of the adjusting arm 3 is installed with a motor 4. The output end of the motor 4 is connected to the rotating shaft. The end of the rotating shaft is fixed with a first screw 41, and the end of the first screw 41 is fixed with a blade. Specifically, a nut is screwed on the first screw 41. The combination of the first screw 41 and the nut can realize the rapid installation and disassembly of the blade to be tested. This design makes it simple and quick to replace different blades for testing, and improves the detection efficiency. At the same time, the nut is screwed to the first screw 41 to ensure the stability of the blade during the detection process and prevent the blade from shifting or loosening due to vibration or rotational force. In this embodiment, the cylinder 2 provides precise force output and can accurately control the height of the adjusting arm 3, thereby ensuring the correct position of the motor 4 and the rotating shaft. It can adapt to blades of different sizes and shapes, thereby improving the versatility of the device. The blade to be tested is fixed by the first screw 41, which enables rapid installation and replacement of the blade. When the blade needs to be replaced for testing, the staff can operate quickly, thereby improving work efficiency.

[0037] The implementation principle of the utility model is as follows: first, the base 1 is installed and the power is turned on. When the blade is to be inspected, the staff installs the blade to be inspected on the first screw rod 41 and fixes it with a nut to ensure that it is tightened. Then, the inspection object 64 is placed in the first inspection chamber 61, and the knob 67 is rotated to press the pressure plate 66 downward to press and fix the inspection object 64. Then, the cylinder 2 is contracted to move the adjustment arm 3 downward to place the blade to be inspected between the two inspection objects 64. Then, the staff rotates the turntable 52 to make the two inspection objects 64 close to each other. The detection components 6 of the first group are brought close to each other so that the blade contacts the detection object. At this time, the motor 4 is turned on, and the motor 4 drives the blade to rotate, leaving scratches on the detection object 64. At this time, the staff rotates one group of detection components 6 to match the deformable block 65 with the detection object 64 of the other group, and then rotates the turntable 52 to squeeze the deformable block 65 with the detection object 64, thereby printing a convex mark 651 on the deformable block 65. The convex mark 651 protrudes from the deformable block 65. The staff measures with a ruler or a scale, and the measurement data is accurate and intuitive.
