Description

Technical Field

[0001] The invention relates to the technical field of rubberized cloth detection, in particular to a device for detecting the elastic tension of rubberized cloth. Background Art

[0002] Dipped cloth is a fabric material treated by a special process. Its core feature is that the base cloth (such as polyester, cotton or glass fiber, etc.) is impregnated in a colloid solution, so that the rubber material evenly penetrates into the gaps between the fibers and forms a protective layer. By immersing the base cloth in the glue solution and drying and curing it, a composite material with both fabric flexibility and glue layer functionality is formed. Different types of dipped cloth need to be tested for their elasticity by stretching. The tensile test is mainly used to determine their elastic deformation ability and tensile strength under stress, measure the ability of the dipped cloth to return to its original shape after being stretched by external force, and test the maximum force value that the dipped cloth can withstand during the stretching process and the elongation before breaking.

[0003] The invention with publication number CN115753394A discloses a mechanism for detecting elastic stretching of rubberized cloth. By setting a first fixed column, a first clamping plate and a first sliding block, the rubberized cloth body is placed above the fixed plate. The user pushes the first clamping plate to drive the first sliding block to slide inside the connecting frame, and the first clamping plate slides inside the first fixed column. The two sides of the rubberized cloth body can be fixed by utilizing the snap connection between the first fixed column and the first clamping plate, and the force is evenly applied to the fixed positions of the four sides of the rubberized cloth to prevent the rubberized cloth from breaking due to uneven force, thereby improving the protective effect of the device on the rubberized cloth.

[0004] The invention with announcement number CN119000299B discloses a fabric stretch detection device. When the end of a thicker elastic fabric is clamped and fixed by two clamping plates in a clamping mechanism, the nail rod in the upper clamping mechanism will be inserted into the fabric at an angle upward, and the nail rod in the lower clamping mechanism will be inserted into the fabric at an angle downward. When the fabric is subjected to tension testing, the nail rod is not easy to detach from the fabric, thereby avoiding the influence caused by deformation when the elastic fabric is stretched, and the fixing effect is good.

[0005] However, the elastic stretching detection mechanism for the rubberized cloth (cloth) disclosed above still has the following problems when in use: although the detection is achieved by the positioning and stretching mechanisms distributed in opposite directions, such positioning mechanisms operate independently and cannot make the left and right ends of the rubberized cloth be pressed with the same force, which can easily cause one side of the rubberized cloth to slide during stretching and affect the test value. At the same time, the rubberized cloth is sticky and easily adheres to the positioning mechanism after being pressed, which affects the subsequent separation and removal.

[0006] Therefore, we propose a device for detecting the elastic tension of rubber-impregnated cloth in order to solve the above-mentioned problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a device for detecting the elastic tension of rubberized cloth, in order to solve the problem that the existing detection is achieved through positioning and stretching mechanisms distributed in opposite directions, but such positioning mechanisms operate separately, and cannot make the left and right ends of the rubberized cloth be pressed with the same force, which easily causes one side of the rubberized cloth to slide during stretching and affects the test value. At the same time, the rubberized cloth is sticky, and after being pressed under force, it is easy to stick to the positioning mechanism more firmly, affecting the subsequent separation and removal.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for detecting the elastic tension of rubberized cloth, comprising a device body, and guide slots provided on the front and rear sides of the top of the device body to achieve internal and external communication; and further comprising:

[0009] A stretching mechanism is provided on both the left and right sides of the top surface of the device body, and the stretching mechanism includes a bidirectional threaded rod, and both the left and right ends of the bidirectional threaded rod are threadedly connected to the bottom end of the stretching slide;

[0010] A positioning mechanism is provided above the symmetrically arranged stretching slide, and the positioning mechanism includes a main positioning tooth plate and an auxiliary positioning tooth plate, and the main positioning tooth plate and the auxiliary positioning tooth plate are distributed in an up-down opposite manner;

[0011] A jacking mechanism is provided in the middle of the top surface of the device body, and the jacking mechanism includes a jacking inclined plate, and a jacking slide plate is slidably fitted on the top surface of the jacking inclined plate.

[0012] Preferably, the bidirectional threaded rod included in the stretching mechanism is rotatably installed on the front and rear sides of the device body through bearings, and the stretching slides on the left and right sides of the bidirectional threaded rod slide through the guide groove inside the device body. The stretching slide and the positioning mechanism above drive the dipped cloth to position and then achieve stretching.

[0013] Preferably, the positioning mechanism includes a positioning top plate, and guide slide rods are slidably installed at the four corners of the bottom surface of the positioning top plate, and the bottom end of the guide slide rod is fixedly installed inside the stretching slide, and the top surface of the stretching slide and the bottom surface of the positioning top plate are respectively fixedly installed with a main positioning tooth plate and a secondary positioning tooth plate.

[0014] Preferably, the positioning mechanism includes a transmission shaft, and the transmission shaft is rotatably installed on the left side of the top surface of the device body through a bearing, and the left end of the transmission shaft is fixedly connected to the output shaft of the servo motor, and the outer wall of the transmission shaft is symmetrically provided with a locking groove.

[0015] Preferably, the positioning mechanism includes a threaded sleeve, and the threaded sleeve is rotatably installed on the front and rear sides of the stretching slide through a bearing, and the bottom ends of the symmetrically distributed threaded sleeves are connected through a pulley assembly, and the internal thread of the threaded sleeve is connected to the lower end of the lifting screw, and the top end of the lifting screw is fixedly connected to the front and rear sides of the interior of the positioning top plate.

[0016] Preferably, the positioning mechanism includes a driven gear fixedly mounted on the outside of the upper end of the threaded sleeve, and a driving gear meshing with the driven gear is rotatably provided on the top surface in front of the stretching slide through a bearing, and the top end of the rotating shaft of the driving gear is meshed with the outer wall of the transmission shaft through a bevel gear group.

[0017] Preferably, the positioning mechanism includes a transmission shaft whose outer wall includes a bevel gear group with symmetrically provided engaging protrusions, and the transmission shaft is slidably connected to the engaging protrusions on the inner side of the bevel gear group through the engaging grooves provided on the outer wall, and a retaining frame is fixedly provided on the outer side of the front end of the stretching slide, and the upper end of the retaining frame is in contact with the outer side of the bevel gear group on the outer wall of the transmission shaft.

[0018] Preferably, the jacking mechanism includes a jacking inclined plate fixedly installed on the left and right sides of the top surface of the device body, and the middle part of the jacking inclined plate is arranged between the stretching slide and the main positioning tooth plate, and the top surface of the jacking slide is fixedly installed with jacking slide tubes at equal distances, and the upper end of the jacking slide tube slides through the outside of the top surface of the main positioning tooth plate.

[0019] Preferably, the jacking mechanism includes an elastic air supply bag, and the elastic air supply bag is fixedly installed at the lower inside of the jacking inclined plate, and the elastic air supply bag and the jacking slide are interconnected through a corrugated conveying pipe, and the jacking slide and the jacking slide are interconnected, so that air is ejected upward through the top of the jacking slide.

[0020] Preferably, the lifting slide included in the lifting mechanism slides outward with the stretching slide and then descends to the inside of the main positioning tooth plate to avoid affecting the engagement of the main positioning tooth plate and the auxiliary positioning tooth plate. When the stretching slide moves inward, the lifting slide and the lifting slide rise, and the jet is used to penetrate the main positioning tooth plate to prevent the pressurized dipped cloth from sticking excessively and affecting separation and removal.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the main positioning tooth plate and the auxiliary positioning tooth plate are used for the elastic tension detection device of the dipped cloth to perform the same pressure positioning on the end of the dipped cloth, and the stretching slide moves outward to perform the stretching detection, and when sliding inward, the positioning slide column cooperates with the air jet to lift the dipped cloth to reduce the stickiness, thereby facilitating the subsequent separation and removal. The specific contents are as follows:

[0022] 1. The end of the dipped cloth is placed on the main positioning tooth plate on the top surface of the stretching slide, and is adhered to the dipped cloth through the jacking slide pipe passing through the top of the main positioning tooth plate, thereby positioning the dipped cloth to avoid wrinkles and dislocation during subsequent pressing and positioning.

[0023] 2. The bidirectional threaded rod inside the device body rotates, driving the threaded stretching slides on the left and right sides and the sticky rubberized cloth to stretch. The jacking slide above the stretching slide gradually slides downward through the inclined surface of the jacking inclined plate, driving the jacking slide tube and the sticky rubberized cloth to descend and contact the main positioning tooth plate to avoid affecting subsequent positioning.

[0024] 3. After the transmission shaft rotates, it drives the driving gear and the driven gear to rotate through the bevel gear group. The driven gear drives the threaded sleeve to rotate, so that the threaded lifting screw drives the auxiliary positioning tooth plate on the positioning top plate and the bottom surface to descend, so that the auxiliary positioning tooth plate and the main positioning tooth plate engage with each other, thereby pressurizing the end of the impregnated cloth.

[0025] The two ends of the rubberized cloth are pressed by the main positioning tooth plate and the auxiliary positioning tooth plate with the same pressing force, thereby preventing the ends of the rubberized cloth from sliding and dislocating when it is subjected to ultimate stretching, affecting its elastic deformation capacity and tensile strength data.

[0026] 4. The stretching slide slides inward, and the jacking inclined plate rises synchronously with the jacking slide tube through the inclined surface to resist the jacking slide plate, so that the impregnated cloths stuck to the top of the main positioning tooth plate are separated from each other. At the same time, after the stretching slide squeezes the elastic air supply bag, it discharges the air through the top of the jacking slide tube through the through-connected corrugated conveying pipe, so as to reduce the degree of adhesion between the impregnated cloth and the jacking slide tube, which is convenient for subsequent separation and removal.

[0027] 5. During the process of testing the stickiness of the impregnated cloth, the outer end of the impregnated cloth is placed on the top surface of the main positioning tooth plate, and the auxiliary positioning tooth plate is driven to slide downward by the positioning top plate, so that the impregnated cloth is adhered to the top surface of the main positioning tooth plate through the sticky surface, and then the main positioning tooth plate is driven to move outward by the stretching slide to detect the stickiness of the impregnated cloth.

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] See also Figures 1-11 , the present invention provides the following technical solutions:

[0042] Example 1: In order to solve the problems existing in the existing elastic tension detection of dipped cloth, this embodiment discloses the following technical solutions: a device for detecting the elastic tension of dipped cloth, comprising a device body 1, and a guide slide 2 opened on the front and rear sides of the top of the device body 1 to realize internal and external penetration; a positioning mechanism is provided above the symmetrically arranged stretching slide 4, and the positioning mechanism includes a main positioning tooth plate 5 and a secondary positioning tooth plate 6, and the main positioning tooth plate 5 and the secondary positioning tooth plate 6 are distributed in an upper and lower opposite manner; the positioning mechanism includes a positioning top plate 9, and guide slide rods 10 are slidably installed at the four corners of the bottom surface of the positioning top plate 9, and the bottom end of the guide slide rod 10 is fixedly installed inside the stretching slide 4, and the top surface of the stretching slide 4 and the bottom surface of the positioning top plate 9 are respectively fixedly installed with the main positioning tooth plate 5 and the secondary positioning tooth plate 6.

[0043] The positioning mechanism includes a transmission shaft 11, and the transmission shaft 11 is rotatably mounted on the left side of the top surface of the device body 1 through a bearing, and the left end of the transmission shaft 11 is fixedly connected to the output shaft of the servo motor, and the outer wall of the transmission shaft 11 is symmetrically provided with a locking groove 12; the positioning mechanism includes a threaded sleeve 13, and the threaded sleeve 13 is rotatably mounted on the front and rear sides of the interior of the stretching slide 4 through a bearing, and the bottom ends of the symmetrically distributed threaded sleeves 13 are connected through a pulley assembly 14, and the internal thread of the threaded sleeve 13 is fixedly connected to the top surface of the device body 1 through a bearing. It is connected to the lower end of the lifting screw 15, and the top of the lifting screw 15 is fixedly connected to the front and rear sides of the interior of the positioning top plate 9; the positioning mechanism includes a transmission shaft 11 included in the outer wall of the bevel gear group 18 with symmetrical engaging protrusions 19 on the inner side, and the transmission shaft 11 is slidably connected to the engaging protrusions 19 on the inner side of the bevel gear group 18 through the engaging groove 12 opened on the outer wall, and a retaining frame 20 is fixedly provided on the outer side of the front end of the stretching slide 4, and the upper end of the retaining frame 20 is in contact with the outer side of the bevel gear group 18 on the outer wall of the transmission shaft 11.

[0044] like Figure 3-Figure 4 、 Figure 9-10 As shown, when performing elastic stretching test on the dipped cloth, the dipped cloth is first placed above the stretching slides 4 on the left and right sides of the top surface of the device body 1, and the outer bottom surface of the dipped cloth is placed in contact with the top of the lifting slide 21 passing through the main positioning tooth plate 5. The dipped cloth is connected to the top surface of the lifting slide 21 through the viscosity of the dipped cloth to avoid wrinkles or dislocations in the subsequent positioning process that affect the stretching test.

[0045] Furthermore, the servo motor drives the transmission shaft 11 on the top surface of the device body 1 to rotate, which is connected to the engaging protrusion 19 on the inner side of the bevel gear group 18 through the engaging groove 12 on the outer wall, thereby driving the connected driving gear 17 and the meshing driven gear 16 to rotate. At the same time, the driven gear 16 drives the threaded sleeve 13 connected through the pulley assembly 14 to rotate inside the stretching slide 4, and the lifting screw 15 threadedly connected to the threaded sleeve 13 is positioned through the positioning top plate 9 at the top, and then the lifting screw 15 drives the positioning top plate 9 to slide downward along the guide slide 10 through threaded transmission, and drives the auxiliary positioning tooth plate 6 on the bottom surface to descend and engage with the main positioning tooth plate 5, so as to press the end of the dipped cloth, and the pressing on the left and right sides is in a synchronous state, so that the pressure is the same, avoiding the situation where one end slips sideways and affects the detection data during subsequent stretching.

[0046] Example 2: In order to solve the problems existing in the existing elastic tension detection of dipped cloth, this embodiment discloses the following technical solution, wherein stretching mechanisms are provided on both the left and right sides of the top surface of the device body 1, and the stretching mechanism includes a bidirectional threaded rod 3, and the left and right ends of the bidirectional threaded rod 3 are threadedly connected to the bottom end of the stretching slide 4; the bidirectional threaded rod 3 included in the stretching mechanism is rotatably installed on the front and back sides of the inside of the device body 1 through bearings, and the stretching slides 4 on the left and right sides of the bidirectional threaded rod 3 slide through the guide slide 2 inside the device body 1, and the stretching slide 4 and the positioning mechanism above drive the dipped cloth to be positioned and then stretched.

[0047] like Figure 2-Figure 3 As shown, the bidirectional threaded rod 3 installed on the front and rear sides of the device body 1 is rotated (the bidirectional threaded rod 3 is driven by the motor built into the device body 1), so that the stretching slide 4 threadedly connected to the left and right sides of the bidirectional threaded rod 3 drives the dipped cloth positioned above to be stretched. The dipped cloth positioned by the engagement of the main positioning tooth plate 5 and the auxiliary positioning tooth plate 6 is subjected to the same pressure at its outer end during stretching, thereby avoiding sliding during the extreme stretching process. At the same time, the fracture detector installed at the rear of the top surface of the device body 1 can perform real-time detection on the dipped cloth during stretching, so as to monitor the tensile limit and fracture position of the dipped cloth.

[0048] Furthermore, during the movement, the stretching slide 4 is in contact with the bevel gear set 18 on the outer wall of the transmission shaft 11 through the retaining frame 20 installed on the front side, thereby preventing the mutually meshing bevel gear sets 18 from falling off during movement and affecting the transmission effect.

[0049] Example 3: In order to solve the problems existing in the existing elastic tension detection of dipped cloth, this embodiment discloses the following technical solution, wherein a lifting mechanism is provided in the middle of the top surface of the device body 1, and the lifting mechanism includes a lifting inclined plate 7, and the top surface of the lifting inclined plate 7 is fitted with a lifting slide 8 for sliding; the positioning mechanism includes a driven gear 16 fixedly mounted on the outside of the upper end of the threaded sleeve 13, and the top surface in front of the stretching slide 4 is provided with a driving gear 17 meshing with the driven gear 16 through a bearing, and the top end of the rotating shaft of the driving gear 17 is meshed with the outer wall of the transmission shaft 11 through a bevel gear group 18.

[0050] The jacking mechanism includes a jacking inclined plate 7 fixedly installed on the left and right sides of the top surface of the device body 1, and the middle part of the jacking inclined plate 7 is arranged between the stretching slide 4 and the main positioning tooth plate 5, and the top surface of the jacking slide 8 is fixedly installed with a jacking slide tube 21 at equal distances, and the upper end of the jacking slide tube 21 slides through the outside of the top surface of the main positioning tooth plate 5.

[0051] The lifting mechanism includes an elastic air supply bag 22, and the elastic air supply bag 22 is fixedly installed at the bottom of the inner part of the lifting inclined plate 7, and the elastic air supply bag 22 and the lifting slide 8 are interconnected through the corrugated conveying pipe 23, and the lifting slide 8 is interconnected with the lifting slide 21, so that the air is ejected upward through the top of the lifting slide 21.

[0052] The lifting mechanism includes a lifting slide 21 that slides outward following the stretching slide 4 and then descends to the inside of the main positioning tooth plate 5 to avoid affecting the engagement of the main positioning tooth plate 5 and the auxiliary positioning tooth plate 6. When the stretching slide 4 moves inward, the lifting slide 8 and the lifting slide 21 rise, and the jet is cooperated with the jet to penetrate the main positioning tooth plate 5 to avoid excessive stickiness of the pressurized impregnated cloth, which affects separation and removal.

[0053] like Figure 2 、 Figure 6 As shown, the stretching slide 4 moving outward drives the upper jacking slide 8 to move synchronously, and the bottom surface of the jacking slide 8 is in contact with the top surface of the jacking inclined plate 7, so that the jacking slide 8 and the jacking slide tube 21 on the top surface gradually descend during sliding, and are finally received inside the main positioning tooth plate 5, so that the dipped cloth can be stably pressed through the main positioning tooth plate 5 and the auxiliary positioning tooth plate 6, without affecting the subsequent elastic stretching test of the dipped cloth.

[0054] After the dipped rubber cloth is inspected, the stretching slides 4 on the left and right sides drive it to move inward, and at the same time, the jacking inclined plate 7 gradually lifts the jacking slide plate 8 and the jacking slide tube 21 upward through the inclined surface, so that the top end of the jacking slide tube 21 passes through the top of the main positioning tooth plate 5, and lifts up the dipped rubber cloth stuck to the top surface of the main positioning tooth plate 5.

[0055] Furthermore, the stretching slide 4 sliding inward squeezes the elastic air supply bag 22 inside the jacking inclined plate 7, so that the elastic air supply bag 22 transports the internal air to the jacking slide 21 through the corrugated conveying pipe 23 and the jacking slide plate 8, and sprays it out from the outside of the top of the jacking slide 21. The air sprayed from the top of the jacking slide 21 further reduces the stickiness of the lifted dipped cloth, so as to facilitate separation and collection by the testers.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
