Description

Technical Field

[0001] The present application relates to the technical field of fabric processing, and in particular to a woven fabric cutting device. Background Art

[0002] With the continuous development of social economy and the increasing improvement of scientific and technological level, my country's textile industry is also booming. As a device for cutting fabrics, weaving cutting equipment can cut fabrics, making it convenient to put fabrics into the next production process, which plays an important role in the textile industry.

[0003] There is a kind of weaving cutting equipment in the prior art, which includes a machine body, a conveyor belt and a cutting mechanism are arranged on the machine body, the conveying direction of the conveyor belt is the length direction of the machine body, and the cutting mechanism is located above the conveyor belt and is used to cut the fabric on the conveyor belt. The machine body is provided with additional frames at both ends along its length direction, and each additional frame is provided with a mounting frame, a lifting member and an abutting roller, and the lifting member is installed on the additional frame and is used to drive the mounting frame to rise and fall. The abutting roller is rotatably connected with the additional frame, and the bottom end of the abutting roller abuts against the fabric on the conveyor belt. One of the additional frames is slidably connected with the machine body, and a driving mechanism is also arranged on the machine body, and the driving mechanism is used to drive the additional frame to slide along the length direction of the machine body. When in use, the two lifting members each drive the corresponding mounting frame to move downward, so that each abutting roller abuts against the fabric, and then the driving mechanism drives one of the additional frames to slide, so that the abutting roller on the additional frame is pressed tightly, driving the fabric to be straightened, and in this process, the cutting mechanism cuts the fabric.

[0004] With regard to the above-mentioned related technologies, in the process of straightening fabrics with poor elasticity and thinness, since the abutment roller has already been pressed against the upper surface of the fabric when the cutting mechanism cuts the fabric, when the abutment roller is driven by the driving mechanism to pull the fabric to be straightened, the fabric is easily damaged by continuous stretching due to the excessive friction between itself and the abutment roller, resulting in pilling or deformation of the fabric, thereby reducing the quality of the fabric after cutting. Utility Model Content

[0005] In order to reduce the probability of damage to the fabric when it is straightened, the present application provides a woven fabric cutting device.

[0006] The present application provides a woven fabric cutting device, which adopts the following technical solution:

[0007] A fabric cutting device comprises a machine body, a conveyor belt and a cutting mechanism. The machine body is also provided with a plurality of additional frames, each of which is provided with a mounting frame, a lifting member and an abutment roller. The lifting member is used to drive the corresponding mounting frame to rise and fall. Each mounting frame is provided with a sliding frame, each of which is slidably connected to the corresponding mounting frame. A pressure spring is also provided between the sliding frame and the mounting frame, and the two ends of the pressure spring are respectively abutted against the sliding frame and the mounting frame. The abutment roller is installed on the sliding frame.

[0008] By adopting the above technical scheme, compared with the prior art, the abutment roller is directly installed on the corresponding mounting frame, so that the abutment roller is displaced with the mounting frame. The present application arranges the sliding frame and the pressure spring so that after the abutment roller contacts the fabric and the mounting frame continues to slide downward under the drive of the lifting member, the sliding frame can slide relative to the mounting frame, thereby compressing the pressure spring, and then controlling the compression amount of the pressure spring to control the tightening effect of the abutment roller on the fabric, thereby reducing the probability of excessive friction between the abutment roller and the fabric, thereby reducing the probability of damage to the fabric when being straightened, and ensuring the quality of the fabric after cutting.

[0009] Preferably, the cutting mechanism includes a driving member and a cutting knife, the cutting knife is slidably connected to the machine body, the driving member is used to drive the cutting knife to slide, one of the additional frames is slidably connected to the machine body, the sliding direction of the additional frame is the conveying direction of the conveyor belt, and a linkage mechanism is also provided on the machine body, and the cutting knife drives the corresponding additional frame to slide through the linkage mechanism.

[0010] By adopting the above technical solution and setting the linkage mechanism, when the cutting knife slides downward under the drive of the driving member, the linkage mechanism can drive the additional frame that slides with the machine body to slide together, so that the abutment roller on the additional frame pulls one side of the fabric, so that the fabric is straightened, thereby ensuring the cutting effect of the fabric. At the same time, the existence of the linkage mechanism can also replace the driving mechanism in the prior art, saving energy consumption.

[0011] Preferably, the linkage mechanism includes a linkage frame, a rotating frame and a driven frame, one end of the linkage frame is rotatably connected to the cutting knife, the other end is rotatably connected to the top end of the rotating frame, the bottom end of the rotating frame is rotatably connected to the machine body, one end of the driven frame is rotatably connected to the top end of the rotating frame, and the other end of the driven frame is rotatably connected to the corresponding additional frame.

[0012] By adopting the above technical solution and specifically arranging the linkage mechanism, when the cutting knife moves downward, the linkage frame can drive the rotating frame to rotate, so that the top end of the rotating frame rotates in a direction away from the cutting knife, and then the rotating frame drives the corresponding additional frame to slide through the driven frame, thereby driving the additional frame. At the same time, the existence of the linkage frame, the rotating frame and the driven frame can also increase the stability of the linkage mechanism, ensure the service life of the linkage mechanism, and reduce the probability of excessive stress between the linkage frame, the rotating frame and the driven frame.

[0013] Preferably, the additional frame slidably connected to the machine body is further provided with rollers, and the rollers abut against the machine body.

[0014] By adopting the above technical solution and setting the roller, the sliding friction between the additional frame and the machine body can be converted into rolling friction between the roller and the machine body, thereby reducing the friction between the machine body and the additional frame, and further reducing the wear between the machine body and the additional frame, thereby ensuring the service life of the additional frame.

[0015] Preferably, the number of the linkage mechanisms is set to be several and arranged along the width direction of the body.

[0016] By adopting the above technical solution, the linkage mechanism is set up in several pieces, which can effectively ensure the linkage effect between the cutting knife and the corresponding additional frame, thereby ensuring the stability of the cutting knife when driving the additional frame, and also ensuring the stability of the additional frame when sliding, thereby ensuring the straightening effect of the fabric.

[0017] Preferably, an extension portion extends upward from the top end of the sliding frame, the extension portion is inserted into the corresponding mounting frame and is slidably connected to the corresponding mounting frame, and the pressure spring is sleeved on the corresponding extension portion.

[0018] By adopting the above technical solution, the setting of the extension part can effectively guide the sliding of the sliding frame. At the same time, the existence of the extension part can also increase the stability of the sliding frame during sliding, thereby reducing the wear of the sliding frame during sliding.

[0019] Preferably, the extension parts and the pressure springs on each of the sliding frames are provided in plurality, and the extension parts correspond to the pressure springs one by one, and each of the pressure springs is sleeved on the corresponding extension part.

[0020] By adopting the above-mentioned technical scheme, the sliding frame and the pressure spring are set to be several, which can further increase the stability of the sliding frame when sliding. At the same time, it can also increase the adjustment range of the elastic force applied to the sliding frame of the present application, thereby effectively increasing the adjustment range of the abutment roller on the fabric, thereby increasing the scope of application of the present application.

[0021] Preferably, each of the abutting rollers is provided with an anti-slip sleeve.

[0022] By adopting the above technical solution, the setting of the sliding sleeve can effectively increase the friction coefficient between the surface of the abutment roller and the fabric, thereby ensuring the straightening effect on the fabric and reducing the probability of the friction force on the fabric being too small due to the abutment roller surface being too smooth.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The setting of the sliding frame and the pressure spring enables the sliding frame to slide relative to the mounting frame after the abutting roller contacts the fabric and the mounting frame continues to slide downward under the drive of the lifting member, so that the pressure spring is compressed, and then the pressing effect of the abutting roller on the fabric is controlled by controlling the compression amount of the pressure spring, thereby reducing the probability of excessive friction between the abutting roller and the fabric, thereby reducing the probability of damage to the fabric when it is straightened, and ensuring the quality of the fabric after cutting;

[0025] 2. The setting of the linkage mechanism enables the cutting knife to slide downward under the drive of the driving member, and can drive the additional frame that slides with the machine body to slide together through the linkage mechanism, so that the fabric is straightened to ensure the cutting effect of the fabric. At the same time, the existence of the linkage mechanism can also replace the driving mechanism in the prior art, saving energy consumption. At the same time, the existence of the linkage frame, the rotating frame and the driven frame can also increase the stability of the linkage mechanism and ensure the service life of the linkage mechanism;

[0026] 3. The setting of the roller can convert the sliding friction between the additional frame and the machine body into rolling friction between the roller and the machine body, thereby reducing the friction between the machine body and the additional frame, and further reducing the wear between the machine body and the additional frame, thereby ensuring the service life of the additional frame.

The cutting knife 32 is fixedly installed at the bottom end of the fixing frame 321, and the blade of the cutting knife 32 is vertically downward.

[0034] Reference Figure 1 and Figure 2 The number of additional frames 4 on the machine body 1 is set to two, and they are respectively located at the two ends of the cutting mechanism 3 along the length direction of the machine body 1. One of the additional frames 4 is fixedly installed on the machine body 1 by bolts. The bottom end of the other additional frame 4 is in an inverted T shape and is embedded in the top wall of the machine body 1. The machine body 1 is provided with two sliding grooves 11 for the bottom ends of the additional frames 4 to be embedded.

The rollers 5 are all installed on the additional frames 4 and are located at the upper and lower sides of the bottom ends of the additional frames 4. The plurality of rollers 5 are respectively against the inner bottom wall and the inner top wall of the sliding groove 11.

[0035] Reference Figure 1The machine body 1 is provided with a plurality of linkage mechanisms 6. In the embodiment of the present application, the number of linkage mechanisms 6 is set to two, and they are respectively located on both sides of the fixed frame 321 along the width direction of the machine body 1. Each linkage mechanism 6 includes a linkage frame 61, a rotating frame 62 and a driven frame 63. The top end of each linkage frame 61 is rotatably connected to the corresponding end of the fixed frame 321 extending out of the machine body 1 through a pin shaft, and the other end of each linkage frame 61 is rotatably connected to the top end of the rotating frame 62 through a pin shaft.

[0036] Reference Figure 1 The bottom end of each rotating frame 62 is rotatably connected to the machine body 1 through a pin, and one end of each driven frame 63 is rotatably connected to the top of the rotating frame 62 through a pin. In the embodiment of the present application, the rotation axis of the rotation connection between the linkage frame 61 and the rotating frame 62 is the same as the rotation axis of the rotation connection between the rotating frame 62 and the driven frame 63. The other end of each driven frame 63 is rotatably connected to the additional frame 4 that slides with the machine body 1 through a pin.

[0037] Reference Figure 1 When the fixed frame 321 slides downward under the drive of the driving member 31, the linkage frame 61 is displaced, thereby driving the top of the rotating frame 62 to rotate away from the fixed frame 321. In this process, the rotating frame 62 drives the driven frame 63 to displace to adapt to the rotation of the rotating frame 62. At this time, the additional frame 4 slidably connected to the body 1 slides in the direction away from the fixed frame 321.

[0038] Reference Figure 1 and Figure 2 , each additional frame 4 is provided with two lifting members 42. In the embodiment of the present application, the lifting member 42 is set as an electric push rod, which is fixedly installed on the top of the additional frame 4 by bolts. The piston rod of the electric push rod is vertically arranged downward and is fixedly connected to the mounting frame 41 by bolts. A plurality of extensions 441 extend upward from the bottom end of each sliding frame 44. In the embodiment of the present application, two extensions 441 are provided at both ends of each sliding frame 44 along the machine width direction. The extensions 441 are integrally formed with the corresponding sliding frame 44.

[0039] Reference Figure 1 and Figure 2 Each extension portion 441 extends vertically upward into the corresponding mounting frame 41 and is slidably connected to the corresponding mounting frame 41. The sliding direction of each extension portion 441 is vertical. The cross-sectional area of ​​the top of each extension portion 441 is larger than the cross-sectional area of ​​the rest of itself. A pressure spring 45 is sleeved on each extension portion 441. The top of each pressure spring 45 abuts against the bottom of the mounting frame 41, and the bottom of each pressure spring 45 abuts against the top of the corresponding sliding frame 44.

[0040] Reference Figure 1and Figure 2 Each abutting roller 43 is rotatably connected to the corresponding sliding frame 44 at both ends along its length direction through bearings. Each abutting roller 43 is sleeved with an anti-slip sleeve 7. In the embodiment of the present application, the anti-slip sleeve 7 is made of rubber. The fabric on the conveyor belt 2 is located on the displacement path of the anti-slip sleeve 7.

[0041] Reference Figure 1 and Figure 2 After the lifting member 42 drives the corresponding mounting frame 41 to move downward, so that the anti-slip cover 7 on the abutting roller 43 abuts against the upper surface of the fabric, when the lifting member 42 continues to drive the mounting frame 41 to move downward, the sliding frame 44 slides relative to the corresponding mounting frame 41. During this process, the pressure spring 45 is compressed, so that the elastic force applied by the pressure spring 45 to the sliding frame 44 gradually increases, so that the abutting force of the abutting roller 43 on the fabric becomes larger, thereby realizing the control of the force between the abutting roller 43 and the fabric.

[0042] The implementation principle of a woven fabric cutting device in the embodiment of the present application is as follows: when the fabric needs to be cut, the lifting member 42 drives the corresponding mounting frame 41 to move downward, so that the anti-slip sleeve 7 on the abutment roller 43 abuts against the upper surface of the fabric. When the lifting member 42 continues to drive the mounting frame 41 downward, the sliding frame 44 slides relative to the corresponding mounting frame 41. During this process, the pressure spring 45 is compressed, so that the elastic force applied by the pressure spring 45 to the sliding frame 44 gradually increases, so that the abutment force of the abutment roller 43 on the fabric becomes larger, thereby achieving control of the force between the abutment roller 43 and the fabric. Then the driving member 31 drives the cutting knife 32 to move downward through the fixed frame 321 to cut the fabric. During this process, the fixed frame 321 drives the corresponding additional frame 4 to slide through the linkage mechanism 6, so that the corresponding abutment roller 43 straightens the fabric.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
