Description

Technical Field

[0001] This utility model belongs to the field of face towel testing technology, and specifically relates to a face towel tensile strength testing device. Background Technology

[0002] Face towels are now a standard item in most households. Most face towels are made of pure cotton, which is not easy to tear. They not only avoid the problem of bacteria and mites growing on towels after prolonged use, but also provide convenience for each use. After use, face towels are also used to wipe tables or floors, making them very practical. Before being mass-produced and entering the market, face towels need to undergo random testing of tensile strength to ensure that their toughness meets the standards.

[0003] Chinese patent CN202222492823.3 discloses a plastic tensile testing device, including a frame base and fixed seats welded to the bottom of both sides of the frame base. The device is characterized by mounting brackets vertically arranged on both sides of the frame base, a workpiece seat mounted in the middle of the frame base via fixing screws, a plastic workpiece placed on the workpiece seat, an assembly channel within the mounting brackets, a tensile mechanism movably mounted within the assembly channel extending towards one side of the workpiece seat, and an upper and lower thickness adaptive mechanism driven and connected to the tensile mechanism mounted on the fixed seats.

[0004] Currently, when conducting random inspections of face towels, the manufacturer's testing personnel typically manually pull the face towels to observe their deformation. However, the physical exertion of the personnel pulling the face towels can cause deviations in the tensile strength test, resulting in inaccurate tensile strength tests and reducing the overall accuracy of the tensile strength test.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a device for testing the tensile strength of a face towel, comprising a fixed base and two auxiliary bevel gears.

One end of each of the two reinforcing rods is connected to a main bevel gear. The two auxiliary bevel gears mesh with the two main bevel gears respectively. The top end of the fixed base is connected to a support frame. A tensile assembly is provided on the fixed base. The tensile assembly includes two first lead screws, four main hinge seats, four auxiliary hinge seats, and two limiting slide rods. The surfaces of the two first lead screws respectively mesh with the two auxiliary bevel gears. The inner sides of the bevel gears are connected. The top ends of the two first lead screws are each connected to a second lead screw. The surfaces of the two first lead screws and the surfaces of the two second lead screws are threadedly connected to connecting plates via lead screw nuts.

[0010] Furthermore, the bottom ends of both first lead screws are rotatably connected to the inner side of the bottom end of the support frame via bearings.

[0011] Furthermore, the other side of each of the four connecting plates is slidably attached to the inner wall of the support frame.

Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a test device for the tensile strength of a face towel, including a fixed base 1 and two auxiliary bevel gears 6. The bottom end of the fixed base 1 is connected to a first drive source 3, and the power output end of the first drive source 3 is connected to two reinforcing rods 4. One end of each of the two reinforcing rods 4 is connected to a main bevel gear 5. The two auxiliary bevel gears 6 are respectively meshed with the two main bevel gears 5. The top end of the fixed base 1 is connected to a support frame 7. The fixed base 1 is provided with a tensile assembly 2, which includes two first lead screws 201, four main hinge seats 204, four auxiliary hinge seats 206, and two limiting slide rods 209. The surfaces of the two first lead screws 201 are respectively in contact with the inner sides of the two auxiliary bevel gears 6. The connection is as follows: the top ends of the two first lead screws 201 are each connected to a second lead screw 202; the surfaces of the two first lead screws 201 and the surfaces of the two second lead screws 202 are threadedly connected to a connecting plate 203 via lead screw nuts; each main hinge seat 204 is respectively disposed on one side of each connecting plate 203; each surface of the main hinge seat 204 is hinged to a connecting rod 205; the surface of each secondary hinge seat 206 is respectively hinged to the inner side of each connecting rod 205; a fixing block 207 is connected to one side of each pair of secondary hinge seats 206; a mechanical claw 208 is connected to one side of each pair of fixing blocks 207; and two limiting slide rods 209 are disposed on the inner side of the bottom end of the support frame 7.

[0030] First, when testing the tensile strength of a face towel, the staff places the sample horizontally between the mechanical grippers 208. Then, the two mechanical grippers 208 clamp the face towel. Next, the first drive source 3 drives the two reinforcing rods 4 to rotate, which in turn drives the two main bevel gears 5 and the auxiliary bevel gear 6 meshing with the main bevel gears 5 to rotate. This drives the two first lead screws 201 to rotate the two second lead screws 202 with opposite thread directions, thereby causing the longitudinal connecting plates 203 to move towards each other. At this point, the longitudinal connecting plates 203 separate in pairs, thus creating a connection at the main hinge seat 204. The hinge action with the secondary hinge seat 206 causes the corresponding connecting rod 205 to tilt accordingly, which in turn drives the two mechanical claws 208 to separate the washcloth to both sides. The mechanical claws 208 will then pull the washcloth to both sides. The tester observes the pulling of the washcloth at this time, such as whether there is any breakage or lint shedding, and obtains the test results of the tensile strength. Compared with manual pulling test, it is more labor-saving and will not affect the accuracy of the tensile strength test results due to human fatigue. In addition, the limiting slide rod 209 improves the stability of the movement of the connecting plate 203 and prevents tilting.

[0031] Two mechanical claws 208 facilitate clamping and limiting the washcloth. The first drive source 3 facilitates the rotation of the reinforcing rod 4 and the main bevel gear 5. The main bevel gear 5 facilitates the rotation of the meshing secondary bevel gear 6, which in turn facilitates the rotation of the first lead screw 201 and the second lead screw 202. This facilitates the separation of the longitudinal connecting plate 203. Under the hinge action of the main hinge seat 204 and the secondary hinge seat 206, the secondary hinge seat 206 tilts accordingly, facilitating the clamping and pulling of the washcloth to both sides. The tester can then observe the pulling condition of the washcloth, such as whether there is breakage or lint shedding. This method facilitates the testing of the washcloth's tensile strength and is more labor-saving than manual pulling tests, avoiding the possibility of human fatigue affecting the accuracy of the tensile strength test results.

[0032] In one embodiment, for the first lead screw 201, the thread direction of each first lead screw 201 is opposite to the thread direction of each second lead screw 202.

[0033] First, when testing the tensile strength of a face towel, the staff places the sample horizontally between the mechanical grippers 208. Then, the two mechanical grippers 208 clamp the face towel. Next, the first drive source 3 drives the two reinforcing rods 4 to rotate, which in turn drives the two main bevel gears 5 and the auxiliary bevel gear 6 meshing with the main bevel gears 5 to rotate. This drives the two first lead screws 201 to rotate the two second lead screws 202 with opposite thread directions, thereby causing the longitudinal connecting plates 203 to move towards each other. At this point, the longitudinal connecting plates 203 separate in pairs, thus creating a connection at the main hinge seat 204. The hinge action with the secondary hinge seat 206 causes the corresponding connecting rod 205 to tilt accordingly, which in turn drives the two mechanical claws 208 to separate the washcloth to both sides. The mechanical claws 208 will then pull the washcloth to both sides. The tester observes the pulling of the washcloth at this time, such as whether there is any breakage or lint shedding, and obtains the test results of the tensile strength. Compared with manual pulling test, it is more labor-saving and will not affect the accuracy of the tensile strength test results due to human fatigue. In addition, the limiting slide rod 209 improves the stability of the movement of the connecting plate 203 and prevents tilting.

[0034] Two mechanical claws 208 facilitate clamping and limiting the washcloth. The first drive source 3 facilitates the rotation of the reinforcing rod 4 and the main bevel gear 5. The main bevel gear 5 facilitates the rotation of the meshing secondary bevel gear 6, which in turn facilitates the rotation of the first lead screw 201 and the second lead screw 202. This facilitates the separation of the longitudinal connecting plate 203. Under the hinge action of the main hinge seat 204 and the secondary hinge seat 206, the secondary hinge seat 206 tilts accordingly, facilitating the clamping and pulling of the washcloth to both sides. The tester can then observe the pulling condition of the washcloth, such as whether there is breakage or lint shedding. This method facilitates the testing of the washcloth's tensile strength and is more labor-saving than manual pulling tests, avoiding the possibility of human fatigue affecting the accuracy of the tensile strength test results.

[0035] In one embodiment, for the first lead screw 201, the bottom ends of both first lead screws 201 are rotatably connected to the inner side of the bottom end of the support frame 7 through bearings, thereby improving the stability of the first lead screw 201 when driving the second lead screw 202 to rotate.

[0036] In one embodiment, for the connecting plates 203, the other side of each of the four connecting plates 203 is slidably attached to the inner wall of the support frame 7, thereby preventing the connecting plates 203 from wobbling when moving horizontally up and down.

[0037] In one embodiment, for the connecting plate 203, the inner side of each pair of connecting plates 203 is slidably connected to the surface of each limiting slide rod 209, thereby further improving the stability of the connecting plate 203 when moving horizontally and preventing the connecting plate 203 from tilting.

[0038] In one embodiment, the two mechanical claws 208 are symmetrically arranged on the left and right sides of the vertical center line of the fixed base 1, which facilitates the clamping of the face towel by the mechanical claws 208 and subsequent random inspection of the face towel's tensile strength.

[0039] In one embodiment, for the aforementioned fixed base 1, the bottom end of the fixed base 1 is connected to two support rods 8, and the surfaces of the two reinforcing rods 4 are respectively rotatably connected to the inner sides of the two support rods 8 and the inner side of the support frame 7, thereby facilitating the provision of support force to the reinforcing rods 4 when the first drive source 3 drives the reinforcing rods 4 to rotate, preventing the first drive source 3 from bearing the weight of the reinforcing rods 4 themselves, and improving the stability of the rotation of the reinforcing rods 4.

[0040] In summary, using the above-mentioned technical solution of this utility model, when it is necessary to test the tensile strength of a face towel, the staff places the sample horizontally between the mechanical grippers 208. Then, the two mechanical grippers 208 are driven to clamp the face towel. Then, the first drive source 3 drives the two reinforcing rods 4 to rotate, which in turn drives the two main bevel gears 5 and the secondary bevel gears 6 meshing with the main bevel gears 5 to rotate. This drives the two first lead screws 201 to drive the two second lead screws 202 with opposite thread directions to rotate, thereby driving the longitudinal connecting plates 203 to move towards each other. That is, at this time, the longitudinal connecting plates 203 are moved in pairs. The phases separate, and under the hinge action of the main hinge seat 204 and the secondary hinge seat 206, the corresponding connecting rod 205 tilts accordingly, which in turn drives the two mechanical claws 208 to separate the washcloth to both sides. The mechanical claws 208 will then pull the washcloth to both sides, and the tester can observe the pulling of the washcloth at this time, such as whether there is any breakage or lint shedding. The operation is simple and saves more physical effort than manual pulling test. There will be no situation where human fatigue affects the accuracy of the tensile strength test results. In addition, the limiting slide bar 209 improves the stability of the movement of the connecting plate 203 and prevents the tilting situation.

[0041] Through the above technical solution, the two mechanical claws 208 facilitate the clamping and limiting of the washcloth, the first drive source 3 facilitates the rotation of the reinforcing rod 4 and the main bevel gear 5, the main bevel gear 5 facilitates the rotation of the meshing secondary bevel gear 6, facilitates the rotation of the first lead screw 201 and the second lead screw 202, facilitates the separation of the longitudinal connecting plate 203, and facilitates the tilting of the secondary hinge seat 206 under the hinge action of the main hinge seat 204 and the secondary hinge seat 206, which facilitates the clamping and pulling of the washcloth to both sides. The tester can observe the pulling condition of the washcloth, such as whether there is breakage or lint shedding. This facilitates the tensile performance testing of the washcloth and is more labor-saving than manual pulling testing, avoiding the situation where human fatigue affects the accuracy of the tensile performance test results.
