Description

Technical Field

[0001] The present invention relates to the technical field of tool sharpness detection, and particularly relates to a device for detecting the sharpness of food knives. Background Art

[0002] The sharpness of food knives directly affects the efficiency and quality of food processing. After the food knives are manufactured, it is usually necessary to detect their sharpness. For example, in the patent with the application number 202322368386.9, a tool sharpness detection mechanism is disclosed, which includes a workbench and side plates. The outer wall of the workbench is connected with a slide rail, a sliding block is arranged inside the slide rail, a sliding groove is opened inside the sliding block, a bidirectional lead screw is connected inside the sliding groove, and one end of the bidirectional lead screw is connected with a motor. In this tool sharpness detection mechanism, through the setting of the bidirectional lead screw and the sliding block, when it is necessary to detect the sharpness of the tool, only need to turn on the motor, so that the motor drives the bidirectional lead screw to rotate, thereby driving the clamp to slide oppositely or reversely inside the sliding groove, adjusting the distance between the clamps to adapt to tools of different lengths and sizes. When adjusted to the appropriate position, then turn on the reciprocating motor to make the tool reciprocate to cut the object placed in the placement groove, thus different from the traditional type of manual testing, and relatively reducing the potential safety hazards.

[0003] Traditionally, the detection of tool sharpness mainly relies on the experience of workers or simple cutting tests to judge the sharpness of the tool. However, only a single tool can be tested at a time, and when testing through the mechanism, after the first test, since the test cutting edge will be left on the test object, during the second test, manual movement and adjustment are required, which is rather troublesome. Summary of the Invention

[0004] To solve the problems in the background art, the present invention provides a device for detecting the sharpness of food knives, which can clamp three groups of knives. Driven by an electric push rod, when the three groups of knives move leftward, it can also drive the outer clamping frame to move downward, and then cut and test the three groups of test objects clamped into the U-shaped clamping frame. And when the outer clamping frame moves rightward to reset, it can also push the test object clamping structure forward for a certain distance, so that the three groups of knives can be tested again.

[0005] A device for detecting the sharpness of food knives provided by the present invention specifically includes: a main body frame, a tool clamping structure, an electric push rod, and a test object clamping structure;

[0006] The tool clamping structure includes an outer clamping frame, side clamping plates, inner pressing plates, round plates, support springs, and top pressing plates;

[0007] The overall external card frame is an inverted U-shaped structure. Outer connecting rods are fixedly connected to the front and rear sides of the external card frame respectively. The outer connecting rods pass upward through the horizontal strip holes on the top side of the main frame, and slide through the round plate and the supporting spring. The top ends of the outer connecting rods are also connected to the top pressing plate through bolts inserted therethrough;

[0008] The side clamping plate is arranged at the front end inside the external card frame, and the inner pressing plate is arranged at the upper end inside the external card frame;

[0009] A fixed pushing plate is also arranged at the right end of the top side of the external card frame. When the outer connecting rod is at the rightmost end of the horizontal strip hole, the top end of the fixed pushing plate is inside the square hole of the main frame;

[0010] The electric push rod is hoisted and fixed inside the main frame through two sets of clamps. The telescopic rod of the electric push rod passes through the vertical sliding hole on the fixed pushing plate and is fixed in position by a nut;

[0011] The test object clamping structure is slidably installed at the lower end inside the main frame and is obliquely opposite to the external card frame up and down;

[0012] A linkage shaft is also installed inside the main frame. An upper linkage gear is installed at the upper end of the linkage shaft, and a lower linkage gear is installed at the lower end. A ratchet mechanism is installed inside the upper linkage gear.

[0013] Further, an upper inclined plate is arranged at the rear end of the top side of the external card frame, and the upper inclined plate is in contact with the inclined pressing plate inside the main frame.

[0014] Further, a wide rack is fixedly installed at the lower end of the rear side of the external card frame, and the wide rack meshes with the upper linkage gear during the movement following the external card frame.

[0015] Further, a side guiding frame is connected to the outer side of the side clamping plate. A clamping spring is sleeved on the side guiding frame and slidably passes through the front side of the external card frame. The end of the long connecting plate on one side of the side clamping plate is connected with an insertion post through a thread, and the other side is connected with a supporting frame through a long connecting plate. A supporting plate is arranged on the upper side of the supporting frame. A U-shaped guiding frame is fixed to the bottom side of the supporting plate. The U-shaped guiding frame slidably passes through the supporting frame. An adjusting screw is also connected to the supporting frame through a threaded engagement. The top end of the adjusting screw is in contact with the bottom side of the supporting plate.

[0016] Further, an upper guiding frame is connected to the top end of the inner pressing plate. A compression spring is sleeved on the upper guiding frame and slidably passes through the top side of the external card frame. Two sets of tool partition plates are also arranged on the bottom side of the inner pressing plate, and the thicknesses of the two sets of tool partition plates are less than the length of the wide rack.

[0017] Further, the test object clamping structure includes a U-shaped clamping frame, a test object clamping plate and a bottom connecting plate;

[0018] There are three groups of U-shaped card frames, and there is a set of test object clamping plates on the inner sides of the three groups of U-shaped card frames respectively. A front guide frame is fixed on the front side of the test object clamping plate. A spring is sleeved on the front guide frame and slidably penetrates through the front side of the U-shaped card frame.

[0019] The bottom connecting plates respectively slide and penetrate through the longitudinal strip holes at the lower end of the inner side of the main frame and are fixedly connected to the bottom sides of the three groups of U-shaped card frames. A driving rack is fixed on one side of the bottom connecting plate, and the driving rack meshes with the lower linkage gear.

[0020] Furthermore, there are conical thorns respectively at the middle and rear sides of the bottom sides of the three groups of U-shaped card frames and on the inner sides of the test object clamping plates.

[0021] Furthermore, when the outer connecting rod is at the leftmost end of the transverse strip hole, the bottom end of the tool does not contact the bottom end of the U-shaped card frame.

[0022] A food ingredient knife sharpness detection device provided by the present invention has the following beneficial effects:

[0023] The present invention can clamp three groups of knives. Driven by the electric push rod, when the three groups of knives move to the left, it can also drive the outer card frame to move downward, and then cut and test the three groups of test objects clamped into the U-shaped card frames. And when the outer card frame moves to the right and resets, it can also push the test object clamping structure forward for a certain distance so that the three groups of knives can be tested again.

[0024] In addition, by setting the knife clamping structure, the three groups of knives are clamped by the side clamping plates and the inner pressing plates, which is convenient for clamping the three groups of knives into the outer card frame. The height of the knife handle can also be adjusted by rotating the adjusting screw rod to make the three groups of knives in an overall horizontal state, so as to facilitate the test of the sharpness of the three groups of knives.

[0025] In addition, by setting the test object clamping structure, by pulling the front guide frame, and under the action of the spring and the conical thorns on the front guide frame, the three groups of test objects (such as pork) are clamped into the three groups of U-shaped card frames to facilitate the test of the sharpness of the knives.

[0026] In addition, during the process of driving the outer card frame to move by the electric push rod, under the relative pressing of the inclined pressing plate and the upper inclined plate, when the three groups of knives move to the left, they drive the outer card frame to move downward, and then cut and test the three groups of test objects clamped into the U-shaped card frames. And when the outer card frame moves to the right and resets, the wide rack meshes with the upper linkage gear, driving the linkage shaft and the lower linkage gear to rotate, and then pushing the test object clamping structure forward for a certain distance so that the three groups of knives can be tested again.

[0043] In order to make the purpose, scheme and advantages of the technical scheme of the present invention clearer, the technical scheme of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the ordinary meanings in the art. The same reference numerals in the drawings represent the same components.

[0044] Example 1: Please refer to Figures 1 to 11 :

[0045] The present invention provides a device for detecting the sharpness of food knives, including: a main frame 1, a tool clamping structure 2, an electric push rod 3 and a test object clamping structure 4;

[0046] The tool clamping structure 2 includes an outer clamping frame 201, a side clamping plate 202, an inner pressure plate 204, a round plate 205, a support spring 206 and a top pressure plate 207;

[0047] The outer clamping frame 201 is of an inverted U-shaped structure as a whole. Outer connecting rods 2012 are fixedly connected to the front and rear sides of the outer clamping frame 201 respectively. The outer connecting rods 2012 respectively pass upward through the horizontal strip holes 101 on the top side of the main frame 1, and slide through the round plate 205 and the support spring 206, and the top ends of the outer connecting rods 2012 are also connected to the top pressure plate 207 through bolt insertion;

[0048] The side clamping plate 202 is arranged at the front end inside the outer clamping frame 201, and the inner pressure plate 204 is arranged at the upper end inside the outer clamping frame 201;

[0049] A fixed push plate 2013 is also arranged at the right end of the top side of the outer clamping frame 201. When the outer connecting rod 2012 is at the rightmost end of the horizontal strip hole 101, the top end of the fixed push plate 2013 is inside the square hole 102 of the main frame 1;

[0050] The electric push rod 3 is fixed to the inner side of the main frame 1 by two sets of clamps, and the telescopic rod of the electric push rod 3 passes through the vertical sliding hole on the fixed push plate 2013 and is fixed by a nut;

[0051] The test object clamping structure 4 is slidably mounted on the inner lower end of the main frame 1 and is diagonally opposite to the outer clamping frame 201;

[0052] A linkage shaft 105 is also installed in the main frame 1 , and an upper linkage gear 1051 is installed at the upper end of the linkage shaft 105 , and a lower linkage gear 1052 is installed at the lower end. A ratchet mechanism is installed inside the upper linkage gear 1051 .

[0053] In the embodiment of the present invention, an upper inclined plate 2011 is provided at the rear end of the top side of the outer card frame 201, and the upper inclined plate 2011 is in contact with the inclined pressure plate 103 on the inner side of the main frame 1. When the outer card frame 201 is driven to move to the left by the electric push rod 3, the inclined pressure plate 103 and the upper inclined plate 2011 are pressed relative to each other, so that the three groups of cutting tools move to the left and also drive the outer card frame 201 to move downward, so as to facilitate the testing of the sharpness of the three groups of cutting tools.

[0054] In the embodiment of the present invention, Figure 5 and Figure 6 As shown, a wide rack 2014 is also fixed to the lower end of the rear side of the outer card frame 201, and the wide rack 2014 meshes with the upper linkage gear 1051 during the movement of following the outer card frame 201. When the outer card frame 201 is driven to move to the left by the electric push rod 3, although the wide rack 2014 meshes with the upper linkage gear 1051, since a ratchet mechanism is installed on the inner side of the upper linkage gear 1051, it will not drive the linkage shaft 105 to rotate. When the outer card frame 201 is driven to move to the right and reset by the electric push rod 3, the wide rack 2014 meshes with the upper linkage gear 1051, driving the linkage shaft 105 and the lower linkage gear 1052 to rotate, and under the meshing action of the lower linkage gear 1052 and the driving rack 4041, the test object clamping structure 4 is pushed forward for a distance.

[0055] In the embodiment of the present invention, Figure 1 , Figure 2 , Figure 9 and Figure 10As shown in the figure, a side guide frame 2023 is connected to the outer side of the side clamping plate 202. A clamping spring is sleeved on the side guide frame 2023 and slidably inserted through the front side of the outer clamping frame 201. The end of the long connecting plate on one side of the side clamping plate 202 is threadedly connected with an inserting post 2021. The other side is connected with a supporting frame 2022 through a long connecting plate. A supporting plate 203 is arranged on the upper side of the supporting frame 2022. A U-shaped guide frame 2031 is fixed to the bottom side of the supporting plate 203. The U-shaped guide frame 2031 is slidably inserted through the supporting frame 2022. An adjusting screw rod 2032 is also threadedly engaged and connected to the supporting frame 2022. The top end of the adjusting screw rod 2032 is in contact with the bottom side of the supporting plate 203. The top end of the inner pressing plate 204 is connected with an upper guide frame 2042. A compression spring is sleeved on the upper guide frame 2042 and slidably inserted through the top side of the outer clamping frame 201. Two groups of tool partition plates 2041 are also arranged on the bottom side of the inner pressing plate 204. The thicknesses of the two groups of tool partition plates 2041 are smaller than the length of the wide rack 2014. By pulling the side guide frame 2023, three tools to be detected are placed side by side inside the outer clamping frame 201. The three tools are separated by the tool partition plates 2041, and the tool handles are placed on the supporting plate 203. Then, the inserting post 2021 passes through the threaded hole at the end of the long connecting plate on one side of the side clamping plate 202 through threads and penetrates into the round holes at the front ends of the three tools to be detected. The inner pressing plate 204 is used to press on the top sides of the three tools, so as to clamp the three tools inside the outer clamping frame 201.

[0056] In the embodiment of the present invention, as Figure 11 shown, the test object clamping structure 4 includes a U-shaped clamping frame 401, a test object clamping plate 402 and a bottom connecting plate 404. There are three groups of U-shaped clamping frames 401. A group of test object clamping plates 402 are respectively arranged inside the three groups of U-shaped clamping frames 401. A front guide frame 4021 is fixed to the front side of the test object clamping plate 402. A spring is sleeved on the front guide frame 4021 and slidably inserted through the front side of the U-shaped clamping frame 401. The bottom connecting plate 404 is respectively slidably inserted through the longitudinal strip holes 104 at the lower end inside the main body frame 1 and is fixedly connected to the bottom sides of the three groups of U-shaped clamping frames 401. A driving rack 4041 is fixed to one side of the bottom connecting plate 404. The driving rack 4041 is meshed with the lower linkage gear 1052. Cone thorns 403 are respectively arranged in the middle, rear side of the bottom sides of the three groups of U-shaped clamping frames 401 and the inner side of the test object clamping plate 402. By pulling the front guide frame 4021 and under the action of the spring on the front guide frame 4021 and the cone thorns 403, three test objects (such as pork) are clamped into the three groups of U-shaped clamping frames 401, so as to test the sharpness of the tool.

[0057] In the embodiment of the present invention, as Figure 7 and Figure 8As shown, when the outer connecting rod 2012 is at the leftmost end of the transverse strip hole 101, the bottom end of the tool does not contact the bottom end of the U-shaped frame 401. During the test of the sharpness of the tool, the U-shaped frame 401 will not be cut, and the tool and the U-shaped frame 401 will not be damaged.

[0058] Specific usage and function of this embodiment: In the present invention,

[0059] By pulling the side guide frame 2023, the three groups of tools to be tested are placed side by side on the inner side of the outer card frame 201, and the three groups of tools are separated by the tool partition plate 2041, and the tool handles are placed on the support plate 203, and then the plug column 2021 is threaded through the threaded hole at the end of the long connecting plate on one side of the side clamping plate 202, and inserted into the circular hole at the front end of the three groups of tools to be tested, and the inner pressure plate 204 is used to press on the top side of the three groups of tools, and the three groups of tools are clamped on the inner side of the outer card frame 201;

[0060] By pulling the front guide frame 4021, under the action of the spring on the front guide frame 4021 and the cone thorn 403, three groups of test objects (such as pork) are clamped into the three groups of U-shaped clamping frames 401;

[0061] Then, the outer clamping frame 201 is driven to move to the left by the electric push rod 3. Under the relative pressure of the inclined pressure plate 103 and the upper inclined plate 2011, the three sets of cutting tools move to the left and also drive the outer clamping frame 201 to move downward, so as to perform cutting tests on the three sets of test objects inserted into the U-shaped clamping frame 401. When the outer clamping frame 201 is driven to move to the right and reset by the electric push rod 3, the wide rack 2014 engages with the upper linkage gear 1051, driving the linkage shaft 105 and the lower linkage gear 1052 to rotate, and under the meshing action of the lower linkage gear 1052 and the driving rack 4041, the test object clamping structure 4 is pushed forward for a distance, so that the three sets of cutting tools can perform cutting tests again.
