Description

Technical Field

[0001] The present invention relates to the technical field of cloth strength detection, and in particular to a coral fleece cloth strength detection device. Background Art

[0002] For coral fleece fabric, fabric strength is one of the key indicators to measure its quality and performance. When testing the tensile strength of coral fleece fabric, a fabric strength testing device is required.

[0003] In order to ensure the compression and fixing strength of the coral fleece fabric during the detection process, the existing detection device often sets a multiple compression form for the two mechanisms for compressing and fixing the two ends of the coral fleece fabric. The multiple compression function needs to be implemented by at least two compression components. However, the numerous compression components on the two compression fixations need to be tightened and loosened in steps, which is cumbersome and inconvenient to operate. As a result, the detection device cannot ensure the efficiency of the tightening operation of the coral fleece fabric while ensuring the stable clamping of the coral fleece fabric, and its practicality is poor. Summary of the Invention

[0004] In view of this, the present invention provides a coral fleece fabric strength detection device to solve the problem that the existing detection device cannot ensure the stable clamping of the coral fleece fabric while taking into account the efficiency of the tightness operation of the coral fleece fabric.

[0005] The technical solution proposed by the present invention is: a coral fleece fabric strength detection device for detecting the tensile strength of coral fleece fabric, specifically comprising a rectangular carrier frame, on which two rectangular holding frames are symmetrically slidably mounted; The wheelbase is shortened and the shifting position is adjusted accordingly, and the two trains are arranged in a row The upper and lower ends of the wheelbase are rotated to form a circle, and the rotation of the wheel base is adjusted accordingly.

[0006] Further, there are two clamping spaces formed by the longitudinal clamping plates and the upper and lower side plates of the rectangular holding frame at intervals. The two end portions of the coral fleece fabric to be detected are in a U-shaped structure, and the upper and lower horizontal cloth layers of these two portions are respectively inserted into the upper and lower clamping spaces formed inside the corresponding rectangular holding frame.

[0007] Further, the longitudinal drive shaft is rotatably and penetratingly fitted with the middle parts of the two vertical side plates of the rectangular holding frame; On the middle section of one long side rod of the rectangular carrier frame, a U-shaped positioning frame is welded and suspended, and the horizontal sliding rod is slidably installed on the U-shaped positioning frame; A handwheel is welded to the head end of the longitudinal drive shaft, and the tail end of the pull rod is rotatably connected to a part of the longitudinal drive shaft close to the horizontal sliding rod.

[0008] Further, two bushings are symmetrically welded to the bottom of the rectangular holding frame, and the two bushings are slidably fitted with the two long side rods of the rectangular carrier frame correspondingly, and the head end of the pull rod is rotatably connected to the bushing at the corresponding position; Two longitudinal sliding plates are symmetrically and slidably installed on the two long side rods of the rectangular carrier frame, and the two longitudinal sliding plates are arranged on both sides of the two rectangular holding frames respectively; A lifting lug is welded to the part of the bottom of the rectangular holding frame between the two bushings, and a tension sensor is connected to the lifting lug and the longitudinal sliding plate in a threaded screwing manner.

[0009] Further, a horizontal drive shaft is rotatably installed through the middle parts of the two short side rods of the rectangular carrier frame, and two externally threaded portions with reverse thread directions are symmetrically provided on the part of the horizontal drive shaft inside the rectangular holding frame, and the two externally threaded portions are threadedly screwed with the two longitudinal sliding plates correspondingly; The tension sensor is located on one side of the horizontal drive shaft.

[0010] Further, two T-shaped brackets are symmetrically welded to the bottoms of both ends of the rectangular carrier frame.

[0011] Further, an electric control box is fixedly installed at a position slightly above the middle of the vertical support rod of one T-shaped bracket.

[0012] Further, a controller adapted to the tension sensor and two contactors for respectively controlling the forward and reverse rotations of the torque motor are arranged inside the electric control box. An LED screen and two push-button switches are embedded and installed on the front side box wall of the electric control box. The two push-button switches are both used to control the start and stop of the torque motor, and respectively control the torque motor to rotate forward and reverse when starting.

[0013] Furthermore, the torque motor is electrically connected to two contactors, the two contactors are electrically connected to the controller, the two tension sensors are communicatively connected to the controller, the two button switches are communicatively connected to the controller, and the controller is communicatively connected to the LED screen.

[0014] The coral fleece fabric strength detection device provided by the present invention has the following beneficial effects: 1. The four longitudinal splints can implement double clamping on the two ends of the coral fleece fabric twice, which can effectively improve the clamping and fixing effect of the testing device on the coral fleece fabric as a whole, and greatly reduce the probability of the two ends of the coral fleece fabric being pulled off from the two rectangular holding frames during the tensile test, ensuring the continuous and normal progress of the testing operation.

[0015] Second, through the power transmission of the chain and the three sprockets, the longitudinal drive shaft is twisted forward and backward, which can drive the two longitudinal drive shafts to rotate synchronously forward and backward, control the synchronous relative sliding of the four longitudinal splints, and complete the loosening and tightening operation of the coral fleece fabric at one time. This can save the tedious steps of twisting the two longitudinal drive shafts forward and backward in steps to loosen and tighten the coral fleece fabric. The operation is convenient, so that the detection device can ensure the clamping stability of the coral fleece fabric while taking into account the loosening and tightening operation efficiency of the coral fleece fabric, and has better practicality.

[0016] 3. The longitudinal drive shaft, the transverse slide bar, the two pull rods and the two shaft sleeves connected to the two pull rods are connected together to form a crank slider mechanism. Through this mechanism, the two rectangular retaining frames and the two shaft sleeves can drive the longitudinal drive shaft, the lower sprocket and the transverse slide bar to slide up and down along the convex positioning frame when they are pushed forward relative to each other. During this process, the two upper sprockets can follow the up and down sliding of the lower sprocket and slide relative to each other. In this way, the three sprockets can follow the relative sliding of the two rectangular retaining frames, change the tensioning form of the chain in real time, and always keep the chain in a tensioned state, ensuring that the longitudinal drive shaft is continuously and effectively connected to the two longitudinal drive shafts, avoiding the relative sliding action of the two rectangular retaining frames, interrupting the transmission connection between the longitudinal drive shaft and the two longitudinal drive shafts, and causing the synchronous driving function of the longitudinal drive shaft to the two longitudinal drive shafts to fail. 4. As can be seen from the above, the relative sliding movement of the two rectangular retaining frames will cause technical obstacles to the configuration of synchronous drive mechanisms for the two longitudinal drive shafts. The present invention overcomes the above technical obstacles by setting the chain's tightening shape to a design that utilizes the above crank slider mechanism for real-time adjustment, and successfully sets up a synchronous drive mechanism for the two longitudinal drive shafts. It has ingenious conception, reasonable design, and excellent performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is a detailed description of the specific details, implementation steps, functions and interrelationships of the above features, as well as their roles in implementing the present invention: During testing, the coral fleece fabric 2 to be tested needs to be clamped and fixed between the two rectangular holding frames 5. After the testing is completed, the tested coral fleece fabric 2 needs to be removed from between the two rectangular holding frames 5. By clamping the two ends of the coral fleece fabric 2, the clamping operation of the coral fleece fabric 2 as a whole between the two rectangular holding frames 5 can be implemented. When clamping the two ends of the coral fleece fabric 2, the upper and lower horizontal fabric layers of the two ends of the coral fleece fabric 2 need to be respectively passed through the upper and lower clamping spaces formed inside the corresponding side rectangular holding frames 5 (refer to Figure 2 When the four vertical clamping plates 504 slide up and down in opposite directions, the upper and lower horizontal cloth layers at both ends of the coral fleece fabric 2 can be pressed and fixed on the upper and lower side plates of the rectangular holding frame 5, thereby clamping the two ends of the coral fleece fabric 2 to be inspected. When the four vertical clamping plates 504 slide up and down in opposite directions, the two ends of the coral fleece fabric 2 can be loosened, and the coral fleece fabric 2 can be disassembled after inspection.

[0032] The two threaded rings 507, the two longitudinal splints 504 and the connecting rod 506 connected therebetween are connected together to form a crank slider mechanism. Through these two sets of such mechanisms, the two longitudinal drive shafts 501 can be rotated forward and reverse synchronously, which can drive the four longitudinal splints 504 to slide up and down synchronously, thereby tightening and loosening the two end portions of the coral fleece fabric 2. Through the power transmission of the chain 8 and the three sprockets 10, the longitudinal drive shaft 7 can be twisted forward and reverse, which can drive the two longitudinal drive shafts 501 to rotate forward and reverse synchronously.

[0033] The transverse drive shaft 102 can rotate forward and reverse through two external threads arranged in counter-rotating directions thereon to drive the two longitudinal slides 103 to slide in reverse or toward each other. When the two longitudinal slides 103 slide in reverse, the two rectangular retaining frames 5 can be driven by two tension sensors 9 to slide in reverse along the two long side rods of the rectangular support frame 1, and the coral fleece fabric 2 to be tested clamped and fixed between the two rectangular retaining frames 5 is pulled and tightened, and the tensile strength test of the coral fleece fabric 2 is performed. When the two longitudinal slides 103 slide in reverse, the two rectangular retaining frames 5 are driven to slide in reverse along the two long side rods of the rectangular support frame 1 to reset, so as to restore the tested coral fleece fabric 2 to a relaxed state, thereby facilitating the disassembly of the tested coral fleece fabric 2; the torque motor 6 can drive the transverse drive shaft 102 in forward and reverse rotation.

[0034] During the detection process, two tension sensors 9 are used to monitor the back tension of the two rectangular holding frames 5 on the coral fleece fabric 2 in real time. The two tension sensors 9 transmit the back tension monitored in real time to the controller. After receiving the two opposite tensions, the controller adds the two tensions and transmits the total tension obtained in real time on the LED screen for real-time viewing by the staff. The total tension is the detection tension that the coral fleece fabric 2 has to withstand. The total tension gradually increases as the horizontal drive shaft 102 continuously pushes the two rectangular holding frames 5 in the back direction. When the total tension value displayed on the LED screen reaches the specified detection tension value, the torque motor 6 is turned off to keep the coral fleece fabric 2 in a taut state under the pulling action of the specified detection tension for a period of time. After the waiting holding time is reached, observe whether the coral fleece fabric 2 is broken or obviously damaged. If so, the tensile strength of the coral fleece fabric 2 is judged to be unqualified, otherwise the tensile strength of the coral fleece fabric 2 is judged to be qualified; the start and stop and forward and reverse rotation functions of the torque motor 6 are respectively controlled by two button switches. The operation process of the inching control is that during the detection process, the button switch used to control the forward rotation of the torque motor 6 is pressed. After the button switch is pressed, it transmits the forward rotation instruction to the controller. After receiving the forward rotation instruction, the controller supplies power to the contactor that controls the forward rotation of the torque motor 6 and controls the contactor to be attracted. After the contactor is attracted, the air cylinder starts the torque motor 6 and controls the torque motor 6 to rotate forward. After the detection is completed, press the other button switch to control the torque motor 6 to reverse.

[0035] The four vertically arranged clamps 504 can respectively implement two double clamping operations on the two end portions of the coral fleece fabric 2, which can effectively improve the clamping and fixing effect of the detection device on the entire coral fleece fabric 2, and greatly reduce the probability of the two end portions of the coral fleece fabric 2 being pulled away from the two rectangular retaining frames 5 during the tensile test process, thereby ensuring the continuous and normal progress of the detection operation.

[0036] Through the power transmission of the chain 8 and the three sprockets 10, the longitudinal drive shaft 7 is twisted forward and backward, which can drive the two longitudinal drive shafts 501 to rotate forward and backward synchronously, and control the synchronous relative sliding of the four longitudinal clamps 504, so as to complete the loosening and tightening operation of the coral fleece fabric 2 at one time. This can save the tedious steps of twisting the two longitudinal drive shafts 501 forward and backward step by step to loosen and tighten the coral fleece fabric 2, and the operation is convenient. The detection device can ensure the clamping stability of the coral fleece fabric 2 while taking into account the loosening and tightening operation efficiency of the coral fleece fabric 2, and has better practicality.

[0037] The longitudinal drive shaft 7, the transverse slide bar 103, the two pull rods 701 and the two shaft sleeves 502 connected to the two pull rods 701 are connected together to form a crank slider mechanism. Through this mechanism, the two rectangular retaining frames 5 and the two shaft sleeves 502 can drive the longitudinal drive shaft 7, the lower sprocket 10 and the transverse slide bar 103 to slide up and down along the convex positioning frame 104 when they are relatively pushed and driven. During this process, the two upper sprockets 10 can slide relative to each other following the up and down sliding of the lower sprocket 10. In this way, the three sprockets 10 can follow the relative sliding of the two rectangular retaining frames 5, change the tightening form of the chain 8 in real time, and always keep the chain 8 in a tightened state, ensuring that the longitudinal drive shaft 7 is continuously and effectively transmitted to the two longitudinal drive shafts 501. The connection avoids the relative sliding movement of the two rectangular retaining frames 5, interrupts the transmission connection between the longitudinal drive shaft 7 and the two longitudinal drive shafts 501, and causes the synchronous drive function of the longitudinal drive shaft 7 on the two longitudinal drive shafts 501 to fail. It can be seen from the above that the relative sliding movement of the two rectangular retaining frames 5 will cause technical obstacles to the configuration of a synchronous drive mechanism for the two longitudinal drive shafts 501. The present invention overcomes the above technical obstacles by setting the tightening form of the chain 8 to a design that utilizes the above crank slider mechanism for real-time adjustment, and successfully sets a synchronous drive mechanism for the two longitudinal drive shafts 501 (the synchronous drive mechanism in the present invention is composed of a chain 8, three sprockets 10 and the longitudinal drive shaft 7). It is ingenious in conception, reasonable in design, and has excellent performance.
