Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tensile testing equipment, in particular to a black tape tensile testing device. BACKGROUND

[0002] Black tape is a kind of adhesive material with diverse functions and wide applications. Its performance and application vary significantly due to different material components, production processes and structural designs. In practical applications, the mechanical properties of black tape, especially the tensile strength, are important indicators for evaluating its quality and applicability. Therefore, it is of great significance to accurately test the tensile properties of black tape.

[0003] Currently, the commonly used testing equipment in the prior art is a general-purpose tensile testing machine. Although such equipment has good testing accuracy and wide applicability, it still has many shortcomings when applied to the detection of black tape. First, such equipment usually only has one clamping mechanism, which results in the testing of only one sample at a time. This single testing mode not only has low efficiency, but also requires the black tape samples to be cut and pretreated one by one before testing, which is a tedious and time-consuming process, increases the possibility of human intervention, and thus introduces human errors, affecting the consistency and accuracy of the test results.

[0004] In addition, since black tape has a single-sided adhesive structure (i.e., one side coated with adhesive), it is prone to sample slipping or even falling off when using traditional clamps for clamping, which affects the stability and reliability of the test data. Although some clamps have anti-slip patterns or grooves on their surfaces to enhance clamping force, due to uneven distribution of adhesive on the surface of the tape and difficulty in effectively controlling the clamping pressure, it is still difficult to fundamentally solve the problem of slipping.

[0005] In view of the above technical defects, it is necessary to design a black tape tensile testing device. The device should have a multi-station synchronous testing function to reduce the sample cutting and pretreatment steps and improve the testing efficiency. At the same time, a more stable clamping structure is adopted to effectively prevent the black tape from slipping or falling off during testing, thereby improving the reliability of the test data.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be described in further detail below with reference to the drawings. It is hereby declared that the up, down, left, right, front, back, inner and outer directions appearing or about to appear in the present application are based on the drawings of the present application, and are not specific limitations on the present application.

[0031] Embodiment: A black tape tensile resistance detection device, as shown in the figure, comprises: Figures 1-5

[0032] The rack 1 is the main load-bearing support carrier of the device;

[0033] The clamping stretching part 2 comprises the extension frames 21 symmetrically arranged on the front side of the rack 1, and the electric push rods 22 are fixedly installed on the extension frames 21. The buckling plates 23 are connected to the telescopic ends of the two electric push rods 22, and the air cylinders 24 with the telescopic ends downward are arranged on the top of the buckling plates 23. The clamping plates 25 are fixedly arranged on the telescopic ends of the air cylinders 24. The telescopic action of the air cylinders 24 can drive the connected clamping plates 25 to move up and down. The clamping plates 25 have protruding ends distributed at intervals for enhancing the fitting effect during clamping;

[0034] ​The transmission part 3 for batch conveying the black tape body 100 to be detected includes side plates 31 fixedly arranged on the left and right sides of the rack 1, and a chain conveying assembly 32 is also arranged around the rack 1. The chain conveying assembly 32 is composed of a driving member (such as a driving motor) and a chain transmission mechanism, which is used to realize cyclic conveying. Here, details are not repeated. The chain conveying assembly 32 is provided with a partition plate 33 on the chain. The partition plate 33 is symmetrically provided with a moving plate 34 inside. The end of the moving plate 34 is provided with a clamping block 35 which is slidably connected with the same side plate 31. The clamping block 35 is provided with a pressure sensor. The clamping block 35 is connected with the same side buckle plate 23. The clamping block 35 is provided with a matching frame 36 which is slidably embedded. The matching frame 36 is matched with the protruding end of the same side clamping plate 25. The matching frame 36 is provided with an elastic member 37 between the inner wall of the corresponding clamping block 35. In this embodiment, the elastic member 37 is a spring which provides necessary elastic support for the reset and movement of the matching frame 36.

[0035] Further, through the cooperative arrangement between the clamping stretching part 2 and the transmission part 3, the chain conveying assembly 32 drives the partition plate 33 to run circularly, realizing the continuous and orderly conveying of the black tape body 100, significantly improving the automation degree and working efficiency of the device, making the detection process more batch, and being suitable for efficient tensile resistance performance detection of multiple batches of black tape bodies 100.

[0036] During clamping, the clamping plate 25 and the clamping block 35 form a concave-convex matching structure through the protruding end and the matching frame 36, thereby enhancing the clamping stability and effectively reducing the risk of the black tape body 100 falling during clamping, further ensuring the accuracy and repeatability of the detection data. In addition, since the matching frame 36 is slidably embedded and cooperates with the elastic member 37, the clamping surface of the clamping block 35 can be adaptively switched between the flat state and the concave-convex matching state during clamping and releasing, which can be flexibly converted between the flat state and the concave-convex matching state, which not only meets the clamping demand, but also facilitates subsequent cleaning treatment, improving the applicability and maintenance efficiency of the device.

[0037] To simplify the pretreatment process, the device adopts the "tear and stick" feeding mode: after the black tape body 100 is directly pulled out from the roll and unfolded, it can be attached between the clamping blocks 35 to complete the assembly operation without additional cutting or positioning treatment, realizing "take and use", further improving the operation convenience and overall detection efficiency.

[0038] As Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the cleaning part 4 further comprises an assembly frame 41 arranged at the bottom of the rack 1, and a hot air blower 44 is arranged on the assembly frame 41. The outlet of the hot air blower 44 is connected with a spray pipe I 45 and a spray pipe II 46. The spray pipe I 45 and the spray pipe II 46 are arranged inside the assembly frame 41, so that the spray pipe I 45 and the spray pipe II 46 can spray hot air to the clamping block 35 to soften the adhesive. The assembly frame 41 is provided with inclined blades 48 arranged in front of and behind the inner wall of the assembly frame 41 and in contact with the clamping block 35. The inclined blades 48 are designed with different inclined angles to better fit the clamping surface of the clamping block 35. In this way, the inclined blades 48 can effectively scrape off the residual adhesive softened by the hot air, achieving efficient cleaning operation.

[0039] Particularly, during the rotating process, the fitting frame 36 of the clamping block 35 is in a non-compressed state, so that the clamping surface is restored to a plane, which can facilitate cleaning, improve cleaning efficiency, and simplify the cleaning process.

[0040] As shown in Figure 6 and Figure 7 , the cleaning part 4 further comprises a filter pipe 47 connected to the air inlet of the hot air blower 44. The tail end of the filter pipe 47 is connected to the assembly frame 41, forming a closed air circulation state. A guide plate 49 is arranged at the rear side of the assembly frame 41 to guide the scraped residual adhesive to be discharged, ensuring that waste does not accumulate to affect subsequent operations.

[0041] As shown in Figure 6 and Figure 7 , the cleaning part 4 further comprises protruding rods 411 arranged symmetrically on the left and right sides of the rear end of the assembly frame 41. A closing frame 42 is hingedly arranged on the rear end of the assembly frame 41. The closing frame 42 is provided with limit plates 43 arranged symmetrically on the left and right sides and connected with the protruding rods 411. The closing frame 42 can be easily opened for maintenance or waste removal.

[0042] As shown in Figure 1 and Figure 8 , the cutting part 5 comprises inclined frames 51 arranged symmetrically on the top of the rack 1. The inclined frames 51 are arranged in a rear-opening angle structure. The cutting knives 52 are arranged on the inclined frames 51 in an inclined state. A leakage frame 53 is arranged on each of the left and right sides of the rack 1 to guide the discharged adhesive tape after cutting.

[0043] Further, the rear-opening angle structure of the inclined frames 51 allows the black tape body 100 to naturally approach the cutting knives 52 during the conveying process. The cutting knives 52 are installed at an inclined angle, which is more consistent with the stress trend of the movement direction of the black tape body 100 during conveying, which helps to realize smooth and continuous cutting action, thereby improving the cutting efficiency and quality.

[0044] As shown inFigure 1 、 Figure 8 and Figure 9 Further, as shown in

[0045] Specifically, since the driving shaft 63 adopts an eccentric structure, the branch end of the poking frame 64 produces periodic displacement changes relative to the attachment barrels 61 during rotation. When the poking frame 64 rotates downward, its branch end gradually embeds between the two attachment barrels 61, and the black tape body 100 attached thereto is naturally adhered to the surface of the attachment barrels 61, thereby achieving automatic peeling of the detected black tape body 100. When the poking frame 64 rotates upward, its branch end gradually separates from the area between the attachment barrels 61 and is exposed, so as to contact and hook a new black tape body 100 to be peeled, completing a new round of peeling cycle.

[0046] In addition, the branch end of the poking frame 64 is in a bent state, which can better adhere to the black tape body 100, ensure stable hooking and effective peeling of the black tape body 100 during rotation, reduce manual intervention, and improve the overall automation degree and operation efficiency.

[0047] As shown in Figure 8 and Figure 9 Further, a horizontal plate 65 is arranged on the extension frame 21, and a U-shaped guide frame 66 is arranged between the two horizontal plates 65. The U-shaped guide frame 66 is designed to be open backward, and the upper end of the U-shaped guide frame 66 passes between the corresponding black tape body 100 and the partition plate 33, for limiting and guiding the black tape body 100. A notch is formed in the lower end of the U-shaped guide frame 66 to allow the branch of the poking frame 64 to pass through, so as to ensure that the poking frame 64 can pass through smoothly during rotation and complete the peeling operation of the black tape body 100.

[0048] In use, first ensure that the device is placed stably, and then prepare the black tape roll batch to be detected. Then, the black tape body 100 is pulled out from the roll and expanded, and the black tape body 100 is adhered between the two clamping blocks 35 of the rear partition plate 33 together with the roll, and the roll is placed outside the clamping blocks 35. The chain conveying assembly 32 is started at the same time, so that the chain runs and drives the partition plate 33 and the components thereon to be conveyed from the rear to the front, and the above operation is repeated, so as to realize the sequential feeding of the black tape body 100 in cooperation with the conveying trend of the whole device.

[0049] The black tape body 100 after feeding gradually moves forward with the conveying until reaching the cutting part 5. Since the inclined frame 51 has an opening angle structure facing backward, the black tape body 100 gradually approaches the cutting knife 52 above it in the process of approaching the inclined frame 51, so as to be cut and separated by the cutting knife 52. The separated roll falls into the frame 53 by inertia and is discharged, completing the cutting operation of the black tape body 100.

[0050] With the continuation of the conveying, the clamping block 35 gradually approaches the clamping and stretching part 2. At this time, the clamping block 35 is along the disengagement side plate 31, and forms a buckling connection with the buckling plate 23 on the same side. Then stop the conveying, start the air cylinder 24, make its telescopic end elongate, drive the connected clamping plate 25 to move downward until the clamping plate 25 is attached to the clamping block 35. Under the action of the protruding end of the clamping plate 25, the embedded frame 36 is pressed and slides down, and the elastic member 37 is deformed accordingly, so that the clamping surface of the clamping block 35 forms a concave matching the protruding end of the clamping plate 25, thereby realizing the concave-convex matching, firmly fixing the end part of the black tape body 100 placed therein, and further stabilizing the detection position of the whole black tape body 100 through the cooperative clamping of the two sides.

[0051] After clamping, start the electric push rod 22 on both sides, make its telescopic end shorten, pull the buckling plate 23 on both sides to move outward, and then drive the clamping block 35 to open to both sides, and the moving plate 34 slides along the partition plate 33 synchronously, so as to exert a stretching force on the black tape body 100 for tensile resistance performance detection, while the pressure sensor on the clamping block 35 collects data in real time and feeds back to the background, achieving tensile resistance detection of the black tape body 100.

[0052] After detection, reset the electric push rod 22 and the air cylinder 24, so that the moving plate 34 and the clamping block 35 return to the original position, the clamping plate 25 is disengaged from the clamping block 35, the embedded frame 36 is released from the limit, and the elastic member 37 is reset, so that the clamping surface of the clamping block 35 returns to the flat state. Then restart the conveying, and the stretched black tape body 100 continues to convey forward, and when passing through the U-shaped guide frame 66, the upper end of the U-shaped guide frame 66 will be embedded between the black tape body 100 and the partition plate 33 by inertia.

[0053] When the stretched black tape body 100 is conveyed to the front end of the device and enters the rotating area, the black tape body 100 is located at the bottom of the frame 1. At this time, the motor 62 is turned on, the drive shaft 63 rotates, and drives the actuating frame 64 to rotate. The actuating frame 64 passes through the lower end slot of the U-shaped guide frame 66, actuating the black tape body 100 that has moved there, causing it to detach and attach to the branch end of the actuating frame 64. As the actuating frame 64 continues to rotate, due to its eccentric setting with the attachment cylinder 61, the branch end with the attached black tape body 100 naturally embeds between the two attachment cylinders 61, causing the black tape body 100 to bend and adhere to the surface of the attachment cylinder 61. Finally, with the further rotation of the actuating frame 64, it detaches from the actuating frame 64 and adheres to the attachment cylinder 61, completing the peeling operation of the black tape body 100 after the stretching test.

[0054] Subsequently, the used clamping block 35 is conveyed into the assembly frame 41. The hot air blower 44 starts working, spraying hot air bidirectionally through nozzle 45 and nozzle 46 to soften the residual adhesive on the surface of the clamping block 35. Then, the clamping block 35 moves to the oblique blade 48, where it scrapes off the remaining adhesive through close contact. At this time, the clamping surface of the clamping block 35 is in a flat state, making it easier to clean and achieving the purpose of efficiently removing residual adhesive.

[0055] Finally, the limiting plate 43 is rotated to disengage it from the protruding rod 411, opening the closing frame 42, and the scraped-off excess adhesive is guided out by the guide plate 49. This completes one cycle of the entire process, achieving batch and integrated pre-processing for the black tape inspection process.

[0056] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
