Description

Technical Field

[0001] The present invention relates to the technical field of fabric detection, and specifically to a wear-resistant sandal fabric detection device and detection method based on conversion of different roughnesses. Background Art

[0002] The fabrics of wear-resistant sandals mainly select rubber, genuine leather or EVA materials. Among them, the sandals made of rubber and EVA materials are more popular with users because they are lighter and have higher wear resistance.

[0003] Before the production of sandals made of rubber and EVA materials, it is necessary to conduct wear resistance tests on the corresponding materials. The wear resistance of the shoe upper is generally determined by the peel strength of its fabric surface layer. The higher the peel strength, the better the quality of the shoes. For this, tests can be carried out by means of grinding and friction.

[0004] When the existing grinding detection device detects roughness, if different roughness detections are required for different materials, at this time, the corresponding friction parts need to be replaced, which involves operations such as installation and disassembly, resulting in a large amount of preparatory work and high operation difficulty in the early stage.

[0005] In order to address the above problems, most of the existing grinding devices have the function of switching friction parts. However, after the friction parts are switched, the stability is poor, and it is easy to deflect when stressed during friction, changing the friction length between the friction roller and the fabric, resulting in unstable detection results and low detection accuracy. Summary of the Invention

[0006] The purpose of the present invention is to provide a wear-resistant sandal fabric detection device and detection method based on conversion of different roughnesses to solve the problems raised in the above background art.

The inclined guiding surface can guide the second convex shaft into the fitting groove.

[0020] As a further solution of the present invention: It further includes:

[0021] A support table is arranged parallel to the workbench, and multiple groups of clamping jaws are rotatably installed on the support table. The rotating shaft of the clamping jaw is of a hollow structure;

[0030] A method for detecting the wear-resistant sandal fabric using the detection device as described above, including the following steps:

[0031] Step 1: Select a friction roller with a suitable roughness according to the material of the sandal fabric. Specifically, by controlling the action of the first electric telescopic rod, drive the support shaft to act relative to the fixed sleeve shaft, and under the cooperation of the first convex shaft and the guiding groove, the friction roller is switched, and the friction roller with the corresponding roughness is located directly above the support table;

[0032] Step 2: Place the sandal fabric to be detected on the support table, and then start the second electric telescopic rod;

[0033] Step 3: The second electric telescopic rod acts to drive the pulley to act along the horizontal groove and the vertical groove in sequence, so that the spiral drive structure acts first and drives the jaw to deflect to fix the sandal fabric, and then the support table rises until the sandal fabric abuts against the friction roller;

[0034] Step 4: Control the motor to rotate, so as to drive the corresponding friction roller to rotate;

[0035] Step 5: Remove the sandal fabric and observe its peel strength.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] Through the arranged guiding groove and the first convex shaft, during the process of the first electric telescopic rod driving the support shaft to perform a lifting action once, the first convex shaft can cooperate with the "Y"-shaped groove to drive the support shaft to rotate, so that the corresponding friction roller can be switched, and thus a friction roller with a suitable roughness can be selected according to actual needs for friction, reducing the workload and operation difficulty. Moreover, when the first convex shaft is in the vertical groove, it can prevent the support shaft from rotating relative to the fixed sleeve shaft, so that when the friction roller rotates to polish the sandal fabric, the position state of the friction roller is more stable and it is prevented from shifting. In addition, the cooperation between the first convex shaft and the vertical groove also has the effect of positioning the transmission shaft, so as to ensure that when the support shaft moves downward, it can drive the transmission shaft to insert into the connecting sleeve, further improving the position stability of the friction roller;

[0038] Through the arranged driving assembly, after the switching of the friction roller is completed, the transmission shaft connected to the friction roller can also be inserted into the connecting sleeve, and under the cooperation of the second convex shaft and the fitting groove, when the motor works, it can drive the corresponding friction roller to rotate. At the same time, due to the relatively long length of the friction roller, the transmission shaft and the bevel gear set can be used to support the friction roller, thereby improving the stability of the friction roller and making the detection result more stable, improving the detection accuracy;

[0039] Through the arranged support table, clamping jaws, screw drive structure and power assembly, when the second electric telescopic rod acts, it can first fix the sandal fabric, and then make the support table move upward and enter the detection station, which are carried out step by step. On the one hand, it improves the logicality of the actions of fixing and lifting the sandal fabric, and on the other hand, it further reduces the amount of manual operation.

Detailed implementation manners

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] In addition, the components in the present invention are referred to as "fixed to" or "arranged on" another component. It can be directly on another component or there may be an intermediate component. When a component is considered to be "connected to" another component, it can be directly connected to another component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation mode.

[0053] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a wear-resistant sandal fabric detection device based on conversion of different roughnesses includes: a workbench 1, a support shaft 2, a first convex shaft 202 and a driving component. When the first electric telescopic rod 5 drives the support shaft 2 to perform a lifting action once, the first convex shaft 202 can cooperate with the "Y"-shaped groove, and drive the support shaft 2 to rotate, so that the corresponding friction roller 21 can be switched, so that a friction roller 21 with a suitable roughness can be selected for friction according to actual needs, reducing the workload and operation difficulty. And when the first convex shaft 202 is in the vertical groove 3012, it can prevent the support shaft 2 from rotating relative to the fixed sleeve shaft 3, so that when the friction roller 21 rotates to polish the sandal fabric, the position state of the friction roller 21 is more stable and its deviation is prevented. Specifically as follows:

[0054] A fixed sleeve shaft 3 is installed on the workbench 1, and a guiding groove 301 is formed on the inner wall of the fixed sleeve shaft 3. Specifically, the guiding groove 301 includes a plurality of groups of "Y"-shaped grooves arranged at equal circumferential intervals in the fixed sleeve shaft 3 and connected end to end in sequence;

[0055] The "Y"-shaped groove includes a first arc-shaped inclined groove 3011, a vertical groove 3012 and a second arc-shaped inclined groove 3013. The length direction of the vertical groove 3012 is parallel to the axial direction of the fixed sleeve shaft 3. The first arc-shaped inclined groove 3011 and the second arc-shaped inclined groove 3013 are located on both sides of the vertical groove 3012 away from the workbench 1. Endpoints a and endpoints b are respectively formed at the connection points of the two sides of the first arc-shaped inclined groove 3011 and the second arc-shaped inclined groove 3013 of adjacent two groups of the "Y"-shaped grooves, and the endpoints a and endpoints b are misaligned in the horizontal plane;

[0056] A first inflection point d is formed at the connection of the first arc-shaped inclined groove 3011 and the vertical groove 3012, a second inflection point e is formed at the connection of the vertical groove 3012 and the second arc-shaped inclined groove 3013, and a third inflection point c is formed at the connection of the second arc-shaped inclined groove 3013 and the first arc-shaped inclined groove 3011. The first inflection point d and the third inflection point c are misaligned in the horizontal plane;

[0057] Specifically, referring to the attached Figure 5, where X represents the movement direction of the first convex shaft 202, and Y represents the descending direction of the support shaft 2. At this time, the end point b is located behind the end point a in the movement direction of the first convex shaft 202, and the third inflection point c is also located behind the first inflection point d in the movement direction of the first convex shaft 202. The end point b is located behind the end point a in the descending direction of the support shaft 2, and the third inflection point c is also located behind the first inflection point d in the descending direction of the support shaft 2.

[0058] The support shaft 2 is slidably sleeved with the fixed sleeve shaft 3. A plurality of friction rollers 21 are arranged at equal circumferential intervals at the upper end of the support shaft 2. Among them, along the circumferential direction of the support shaft 2, the roughness of the circumferential surfaces of the plurality of friction rollers 21 gradually changes;

[0059] The first convex shaft 202 is arranged at equal circumferential intervals on the support shaft 2. The first convex shaft 202 is matched with the guide groove 301, and when the support shaft 2 performs a lifting action relative to the fixed sleeve shaft 3 once, the support shaft 2 can be rotated by a predetermined angle;

[0060] An annular groove 201 is formed on the support shaft 2. A collar 4 is rotatably sleeved in the annular groove 201. The collar 4 is connected to a first electric telescopic rod 5 arranged on the workbench 1.

[0061] In this embodiment, a total of three groups of friction rollers 21 are provided. Correspondingly, three groups of first convex shafts 202 and three groups of "Y"-shaped grooves are provided. And in the initial state, the first convex shaft 202 is at the lower end of the vertical groove 3012 on one group of "Y"-shaped grooves. At this time, the first convex shaft 202 is matched with the vertical groove 3012, which can prevent the support shaft 2 from rotating relative to the fixed sleeve shaft 3, so that when the friction rollers 21 rotate to polish the sandal fabric, the position state of the friction rollers 21 is more stable and prevent them from shifting.

[0062] When switching the friction rollers 21, control the first electric telescopic rod 5 to act. At this time, the action end of the first electric telescopic rod 5 can drive the connected collar 4 to move upward, and thereby drive the support shaft 2 to move upward. During this process, the first convex shaft 202 will move upward along the vertical groove 3012 until the first convex shaft 202 abuts against the upper top wall of the second arc-shaped inclined groove 3013. Under the guidance of the upper top wall of the second arc-shaped inclined groove 3013, the support shaft 2 will rotate to drive the friction rollers 21 to perform a circular motion. And when the first convex shaft 202 moves to the end of the second arc-shaped inclined groove 3013 (i.e., the end point a), the first electric telescopic rod 5 will drive the support shaft 2 to move downward. At this time, the first convex shaft 202 will enter the vertical groove 3012 in another group of "Y"-shaped grooves under the guidance of the lower side wall of the first arc-shaped inclined groove 3011, so that the support shaft 2 continues to rotate and is locked.

[0063] With the above settings, during the process of the first electric telescopic rod 5 driving the support shaft 2 to perform a lifting action once, the first convex shaft 202 can cooperate with the "Y"-shaped groove, so as to drive the support shaft 2 to rotate, enabling the corresponding friction roller 21 to be switched. Thus, it is possible to select a friction roller 21 with an appropriate roughness for friction according to actual needs, reducing the workload and operation difficulty. Moreover, when the first convex shaft 202 is in the vertical groove 3012, it can prevent the support shaft 2 from rotating relative to the fixed sleeve shaft 3, making the position state of the friction roller 21 more stable when the friction roller 21 rotates to polish the sandal fabric and preventing it from shifting.

[0064] Please refer to Figure 3 , Figure 6 , the drive assembly is arranged on the workbench 1 and includes a transmission shaft 7 and a connecting sleeve 8. When the transmission shaft 7 and the connecting sleeve 8 are combined, the drive assembly can drive the friction roller 21 to rotate. The drive assembly further includes a motor 9 fixedly installed on the workbench 1, and the output shaft of the motor 9 is connected to the connecting sleeve 8. Specifically, the motor 9 is installed at the bottom of the workbench 1, and the output shaft of the motor 9 penetrates through the workbench 1 and is connected to the connecting sleeve 8;

[0065] A plurality of second convex shafts 701 are arranged on the transmission shaft 7 at equal circumferential intervals. The transmission shaft 7 is connected to the rotating shaft of the friction roller 21 through a bevel gear set 6. Since the friction roller 21 is relatively long, at this time, the transmission shaft 7 and the bevel gear set 6 can be used to support the friction roller 21, thereby improving the stability of the friction roller 21;

[0066] A plurality of fitting grooves 801 are arranged on the inner wall of the connecting sleeve 8 at equal circumferential intervals. Two inclined guiding surfaces 802 extend from the upper end of the fitting groove 801, and the two inclined guiding surfaces 802 between two adjacent fitting grooves 801 intersect. The inclined guiding surfaces 802 can guide the second convex shaft 701 into the fitting groove 801.

[0067] When the first convex shaft 202 is in the vertical groove 3012, the second convex shaft 701 is in the fitting groove 801. At this time, when the output shaft of the motor 9 rotates to drive the connecting sleeve 8 to rotate, the transmission shaft 7 can drive the friction roller 21 to rotate through the bevel gear set 6. When the support shaft 2 performs a lifting action to switch the friction roller 21 with the corresponding roughness, when the first convex shaft 202 moves upward along the vertical groove 3012, the second convex shaft 701 will also move upward along the fitting groove 801. Before the first convex shaft 202 abuts against the upper wall of the second arc-shaped inclined groove 3013, the transmission shaft 7 and the connecting sleeve 8 are completely misaligned (the second convex shaft 701 is separated from the fitting groove 801). At the same time, when the support shaft 2 rotates, the transmission shaft 7 connected to the friction roller 21 with the corresponding roughness will rotate to directly above the connecting sleeve 8. Subsequently, when the support shaft 2 moves downward, the transmission shaft 7 will be inserted into the connecting sleeve 8 again (the second convex shaft 701 enters the fitting groove 801), so that after the friction roller 21 is switched, when the motor 9 works, it can drive the switched friction roller 21 to rotate.

[0068] From the above working process, it is not difficult to conclude that the cooperation between the first convex shaft 202 and the vertical groove 3012 also has the effect of positioning the transmission shaft 7, so as to ensure that when the support shaft 2 moves downward, it can drive the transmission shaft 7 to be inserted into the connecting sleeve 8, ensuring that when the motor 9 works, it can drive the corresponding friction roller 21 to rotate.

[0069] Furthermore, when the transmission shaft 7 moves downward, the first convex shaft 202 can enter the fitting groove 801 under the guidance of the inclined guiding surface 802, and the inclined guiding surface 802 plays an anti-fooling effect, thereby improving the smoothness of the combination of the first convex shaft 202 and the fitting groove 801.

[0070] Through the above settings, after the friction roller 21 is switched, the transmission shaft 7 connected to the friction roller 21 can also be inserted into the connecting sleeve 8, and under the cooperation of the second convex shaft 701 and the fitting groove 801, when the motor 9 works, it drives the corresponding friction roller 21 to rotate.

[0071] Please refer to Figures 7 to 10 , the wear-resistant sandal fabric detection device based on different roughness conversions further includes: a support table 12, a screw drive structure, and a power assembly.

[0072] The support table 12 is parallel to the workbench 1, and multiple groups of clamping jaws 13 are rotatably installed on the support table 12. The rotating shaft of the clamping jaws 13 is a hollow structure. Among them, a telescopic rod 11 is connected to the support table 12, and the telescopic rod 11 is slidably sleeved with a guiding sleeve 10 arranged on the workbench 1;

[0073] The spiral drive structure is connected to the jaw 13, and the spiral drive structure can drive the jaw 13 to deflect towards the support table 12 to clamp the sandal fabric placed on the support table 12;

[0074] The spiral drive structure includes a transverse movement shaft 14 that is slidably sleeved on the rotating shaft of the jaw 13, and a spiral groove 1401 is provided in the axial direction of the transverse movement shaft 14;

[0075] The third convex shaft 1301 provided on the inner wall of the jaw 13 can slide in the spiral groove 1401.

[0076] When the transverse movement shaft 14 moves along the length direction of the rotating shaft of the jaw 13, the spiral groove 1401 can cooperate with the third convex shaft 1301 to drive the jaw 13 to rotate, and when the jaw 13 rotates towards the support table 12, it can fix the sandal fabric on the support table 12 to prevent the sandal fabric from shifting during the test.

[0077] Please refer to again Figures 7 to 10 , the power assembly is connected to the support table 12 and the transverse movement shaft 14, and the power assembly can drive the spiral drive structure to act and drive the support table 12 to move towards the friction roller 21 in sequence. The power assembly includes a second electric telescopic rod 16 and a guide plate 18 provided on the workbench 1. A vertical groove 1801 and a horizontal groove 1802 are provided on the guide plate 18. A pulley 17 connected to the moving end of the second electric telescopic rod 16 can roll in the vertical groove 1801 and the horizontal groove 1802. Among them, the second electric telescopic rod 16 is inclined;

[0078] The power assembly further includes a connection structure connecting the pulley 17, the support table 12 and the transverse movement shaft 14. The connection structure includes a connecting frame 15 connected to the rotating shaft of the pulley 17, and the connecting frame 15 is connected to the transverse movement shaft 14;

[0079] The connection structure further includes a support plate 19 connected to the rotating shaft of the pulley 17. A sliding connection portion 1901 is provided at one end of the support plate 19, and the sliding connection portion 1901 can slide in a guide member 20 installed on the support table 12.

[0080] In the initial state, the pulley 17 is at one end of the horizontal groove 1802 away from the vertical groove 1801. At this time, the clamping jaws 13 are in the open state, and at the same time, the support platform 12 is in a state away from the friction roller 21. After placing the sandal fabric on the support platform 12, the second electric telescopic rod 16 is controlled to act. At this time, the second electric telescopic rod 16 will drive the pulley 17 to act. In this process, the pulley 17 will first move along the horizontal groove 1802, driving the transverse movement shaft 14 to move transversely, causing the clamping jaws 13 to deflect and clamp the sandal fabric. Then the pulley 17 moves along the vertical groove 1801 to drive the support platform 12 to move upward until the sandal fabric abuts against the friction roller 21 and reaches the detection station.

[0081] Through the above settings, when the second electric telescopic rod 16 acts, the sandal fabric can be fixed first, and then the support platform 12 can be moved upward to enter the detection station. The two are carried out step by step. On the one hand, it improves the logicality of the actions of fixing and lifting the sandal fabric. On the other hand, it further reduces the amount of manual operation.

[0082] A method for detecting a wear-resistant sandal fabric using the detection device as described above includes the following steps:

[0083] Step 1: Select a friction roller 21 with an appropriate roughness according to the material of the sandal fabric. Specifically, by controlling the first electric telescopic rod 5 to act, driving the support shaft 2 to act relative to the fixed sleeve shaft 3, and under the cooperation of the first convex shaft 202 and the guiding groove 301, the friction roller 21 is switched, and the friction roller 21 with the corresponding roughness is positioned directly above the support platform 12;

[0084] Step 2: Place the sandal fabric to be detected on the support platform 12, and then start the second electric telescopic rod 16;

[0085] Step 3: The second electric telescopic rod 16 acts, driving the pulley 17 to move along the horizontal groove 1802 and the vertical groove 1801 in sequence, causing the spiral drive structure to act first and driving the clamping jaws 13 to deflect to fix the sandal fabric, and then the support platform 12 rises until the sandal fabric abuts against the friction roller 21;

[0086] Step 4: Control the motor 9 to rotate to drive the corresponding friction roller 21 to rotate;

[0087] Step 5: Remove the sandal fabric and observe its peel strength.
