Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production auxiliary equipment, in particular to a non-woven fabric stretching device. Background Art

[0002] When non-woven fabrics are produced and processed, tensile tests need to be carried out on them to avoid waste of work and materials due to unqualified products being found only after they are put on the machine; and the existing Chinese patent with the application number: 202222537660.6 discloses a non-woven fabric constant force tensile test device, including non-woven fabric clamps and a non-woven fabric body. There are two groups of the non-woven fabric clamps, and the two groups of non-woven fabric clamps are respectively connected to both ends of the non-woven fabric body. A fixing device is arranged on the surface of the non-woven fabric clamp above the non-woven fabric body, and a heavy hammer is fixedly installed on the bottom wall of the non-woven fabric clamp below the non-woven fabric body.

[0003] When the above technology is used, by clamping the non-woven fabric with two clamps and then hanging weights on the lower clamp, although it has a certain degree of non-woven fabric stretching detection effect, in the actual use process, due to its overly simple structure, when personnel detect the stretching length and rebound length of the non-woven fabric, additional measuring rulers are required for measurement, making the device less convenient to use; therefore, in order to solve the above technical problems, we propose a non-woven fabric stretching device. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a non-woven fabric stretching device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A non-woven fabric stretching device includes a mounting plate. Guide rails are symmetrically installed on the front side of the mounting plate. A set of sliders are installed at both the upper and lower ends of the guide rails. A fixing plate is commonly installed on the front side of the sliders at the upper end of the guide rails, and a base is commonly installed on the front side of the sliders at the lower end of the guide rails. Clamping plates are installed on the front sides of the mutually remote ends of the fixing plate and the base through bolts. The upper and lower ends of the non-woven fabric are clamped between the clamping plates, the fixing plate, and the base. A liquid storage cavity is arranged inside the base. One end of the fixing plate is connected to a driving component for driving it to move up and down. A sliding sleeve is arranged on one side of the base, and a column is slidably inserted inside the sliding sleeve. The upper and lower ends of the column are fixedly connected to the mounting plate, and scale marks are arranged on the outer circumferential surface of its rod body.

[0007] Preferably, the driving component includes a motor and a threaded rod. The motor is arranged at one end of the mounting plate, and the output end of the motor is connected to one end of the threaded rod. A threaded cylinder is arranged at one end of the fixing plate and is connected to the threaded rod. The threaded rod is located on the side away from the column.

[0008] Preferably, a placement board is provided at the bottom of the mounting board, and a liquid storage box is provided on the upper surface of the placement board.

[0009] Preferably, a drain pipe is provided at the bottom of the liquid storage chamber of the base, and a valve is provided on the pipe body of the drain pipe.

[0010] Preferably, rubber strips are provided on one side of the clamping plate, the fixing plate and the base away from the bolt, and anti-slip lines are provided on the surface of the rubber strips.

[0011] Preferably, the bolt is a claw bolt, and the base is a transparent seat body.

[0012] Preferably, injection ports are provided at both ends above the liquid storage chamber, and sealing plugs are provided in the injection ports.

[0013] A non-woven fabric stretching device proposed by the present utility model has the following beneficial effects:

[0014] 1: In the present utility model, since one end of the base is slidably sleeved with the column, and scale lines are provided on the surface of the column, that is, the operator only needs to compare the position of the scale lines between the fixing plate and the base at this time to obtain the stretching length of the non-woven fabric. Then, after taking out the non-woven fabric from between the clamping plate and the base, the rebound length can be measured through the column; at the same time, by injecting liquid into the liquid storage chamber to control the total weight of the base, different weights of the base can be used to stretch and measure the non-woven fabric to different degrees. That is, not only can the stretching force feedback to the non-woven fabric be precisely fine-tuned, but also the phenomenon that a large number of heavy weights are easily lost accidentally is avoided.

[0015] 2: The setting of the driving component in the present utility model enables the motor to drive the threaded rod to rotate, and when the threaded rod rotates, it can drive the fixing plate to move up and down. Therefore, when the operator needs to connect or separate the non-woven fabric from the fixing plate, the driving component can be used to conveniently drive the fixing plate to move downward, thus facilitating the separation or combination between the non-woven fabric and the fixing plate; the setting of the liquid storage box is convenient for storing liquid, so that the operator can inject the liquid in the liquid storage box into the liquid storage chamber, thereby increasing the gravity exerted by the base on the non-woven fabric, or pumping the liquid in the liquid storage chamber into the liquid storage box to reduce the gravity exerted by the base on the non-woven fabric; the setting of the rubber strip not only improves the clamping effect of the clamping plate on the non-woven fabric, but also reduces the phenomenon of scratching the surface of the non-woven fabric by the clamping plate.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Embodiment 1

[0023] Refer to Figures 1 - 4 , A non-woven fabric stretching device, including a mounting plate 1, guide rails 2 are symmetrically mounted on the front side of the mounting plate 1, a set of slide blocks 3 are mounted at both the upper and lower ends of the guide rails 2, a fixed plate 5 is commonly mounted on the front side of the slide blocks 3 located at the upper end of the guide rails 2, a base 6 is commonly mounted on the front side of the slide blocks 3 located at the lower end of the guide rails 2, clamping plates 8 are mounted on the front sides of the mutually remote ends of the fixed plate 5 and the base 6 through bolts 7, the upper and lower ends of the non-woven fabric are clamped between the clamping plates 8, the fixed plate 5 and the base 6, a liquid storage cavity 9 is provided inside the base 6, one end of the fixed plate 5 is connected to a driving component for driving it to move up and down, a sliding sleeve is provided on one side of the base 6 and a column 10 is slidably inserted inside the sliding sleeve, the upper and lower ends of the column 10 are fixedly connected to the mounting plate 1 and scale lines are provided on the outer circumferential surface of its rod body.

[0024] Embodiment 2

[0025] Refer to Figures 1 - 4 , In the case where other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 is:

[0026] The driving assembly includes a motor 11 and a threaded rod 12. The motor 11 is arranged at one end of the mounting plate 1, and the output end of the motor 11 is connected to one end of the threaded rod 12. One end of the fixing plate 5 is provided with a threaded cylinder and is connected to the threaded rod 12. The threaded rod 12 is located on the side away from the column 10. The setting of the driving assembly enables the motor 11 to drive the threaded rod 12 to rotate. When the threaded rod 12 rotates, it can drive the fixing plate 5 to move up and down. Thus, when the operator needs to connect or separate the non-woven fabric from the fixing plate 5, the driving assembly can conveniently drive the fixing plate 5 to move downward, thereby facilitating the separation or combination between the non-woven fabric and the fixing plate 5. A placement plate is provided at the bottom of the mounting plate 1, and a liquid storage box 13 is arranged on the upper surface of the placement plate. The setting of the liquid storage box 13 facilitates storing liquid, so that the operator can inject the liquid inside the liquid storage box 13 into the liquid storage cavity 9, thereby increasing the gravity exerted by the base 6 on the non-woven fabric or pumping the liquid inside the liquid storage cavity 9 into the liquid storage box 13, thus reducing the gravity exerted by the base 6 on the non-woven fabric. A drain pipe 14 is arranged at the bottom of the liquid storage cavity 9 of the base 6, and a valve is provided on the pipe body of the drain pipe 14. The setting of the drain pipe 14 facilitates the operator to control the total weight of the base 6, thereby facilitating the control of the gravity exerted by the base 6 on the non-woven fabric, that is, facilitating the control of the stretching of the non-woven fabric.

[0027] Rubber strips 15 are provided on the clamping plate 8, the fixing plate 5, and the side of the base 6 away from the bolt 7. Anti-slip patterns are provided on the surface of the rubber strips 15. The setting of the rubber strips 15 not only improves the clamping effect of the clamping plate 8 on the non-woven fabric but also reduces the phenomenon of scratching the surface of the non-woven fabric by the clamping plate 8. The bolt 7 is a toggle bolt, and the base 6 is a transparent seat body. The setting of the toggle bolt facilitates the operator to rotate the bolt 8. Liquid injection ports are provided at both ends on the upper side of the liquid storage cavity 9, and sealing plugs 4 are arranged in the liquid injection ports. The setting of the sealing plugs 4 facilitates sealing the inside of the liquid storage cavity 9, thereby preventing the liquid inside from being contaminated.

[0028] Principle of use and advantages: During the use of the utility model, the mounting plate 1 is fixed on an external vertical mounting surface. Subsequently, when a tensile test needs to be performed on the non-woven fabric, the operator first drives the threaded rod 12 to rotate through the motor 11, thereby controlling the fixed plate 5 to move downward until the operator's upper limb can conveniently operate the clamping plate 8 at the fixed plate 5. Then, the upper end of the non-woven fabric is clamped between the clamping plate 8 and the fixed plate 5, and then the lower end of the non-woven fabric is clamped between the clamping plate 8 and the base 6. At this time, as the fixed plate 5 continues to move, the non-woven fabric is stretched until the non-woven fabric is stretched to the maximum. During this process, since one end of the base 6 is slidably sleeved on the column 10 and the surface of the column 10 is provided with scale lines, that is, the operator only needs to compare the scale line positions between the fixed plate 5 and the base 6 at this time to obtain the length of the non-woven fabric at this time. Then, subtracting the original length of the non-woven fabric before stretching from the length at this time can obtain the tensile data of the non-woven fabric. Further, after the operator removes the non-woven fabric from between the clamping plate 8 and the base 6, the rebound length of the non-woven fabric can be measured through the column 10. At the same time, during the above process, the operator can control the total weight of the base 6 by injecting liquid into the liquid storage cavity 9, so that bases 6 of different weights can be used to perform tensile measurements on the non-woven fabric to different degrees. And because the weight of the base 6 is controlled by liquid, when the device is in use, there is no need to set multiple fixed-weight weights, that is, not only can the tensile force feedback from the device to the non-woven fabric be accurately fine-tuned, but also the phenomenon that a large number of weights are easily lost accidentally is avoided.

[0029] It should be further noted that the setting of the driving component enables the motor 11 to drive the threaded rod 12 to rotate, and when the threaded rod 12 rotates, it can drive the fixed plate 5 to move up and down. Therefore, when the operator needs to connect or separate the non-woven fabric from the fixed plate 5, the fixed plate 5 can be conveniently driven to move downward through the driving component, thereby facilitating the separation or combination between the non-woven fabric and the fixed plate 5. The setting of the liquid storage box 13 is convenient for storing liquid, so that it is convenient for the operator to inject the liquid in the liquid storage box 13 into the liquid storage cavity 9, thereby increasing the gravity exerted by the base 6 on the non-woven fabric or pumping the liquid in the liquid storage cavity 9 into the liquid storage box 13, thereby reducing the gravity exerted by the base 6 on the non-woven fabric. The setting of the rubber strip 15 not only improves the clamping effect of the clamping plate 8 on the non-woven fabric, but also reduces the phenomenon that the clamping plate 8 scratches the surface of the non-woven fabric. The bolt 7 is a toggle bolt, and the base 6 is a transparent seat body. The setting of the toggle bolt facilitates the operator to rotate the bolt 8. The setting of the sealing plug 4 is convenient for sealing the inside of the liquid storage cavity 9, thereby preventing the liquid inside from being contaminated.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
