Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, and specifically relates to a device for evenly sizing textile fabrics. Background Art

[0002] A device for evenly sizing textile fabrics is equipment in the textile industry used to evenly coat the surface of a fabric body with sizing agent; its main function is to evenly size the surface of the fabric body through a certain process, thereby enhancing the properties of the fabric body, such as wrinkle resistance, gloss, hand feeling, dimensional stability, etc.; although the commonly used sizing devices can size the entire fabric body, there are certain defects in technology; the commonly used sizing devices cannot well control the thickness, evenness, and flatness of the sizing on the surface of the fabric body, resulting in uneven sizing of the fabric body.

[0003] In response to the above problems, some solutions have been proposed in the prior art. For example, Chinese Patent Application No.: CN202110159230.2 discloses a device for sizing a fabric body. In this solution, a first drive roller, a sizing roller, a second drive roller, and a third drive roller are sequentially arranged in a box along the transmission direction of the fabric body. An upper sizing tank and a recovery tank are provided on the inner bottom wall of the box. Above the recovery tank, a support is provided in the box, and the supports are respectively located above and below the fabric body. A sizing mechanism for evenly sizing the fabric body is symmetrically installed on each support. This solution transports the fabric body into the upper sizing tank through the first drive roller, the sizing roller, the second drive roller, and the third drive roller. When the fabric body is fully saturated with the sizing agent, the excess sizing agent on the upper and lower surfaces of the fabric body is scraped off through the sizing mechanism, and the parts of the fabric body that are not sized or have insufficient sizing are filled with sizing agent to make the sizing of the fabric body uniform; however, there are still some problems with the above solution. When sizing a fabric body with a relatively high yarn density, simply sizing by the impregnation method cannot evenly penetrate the sizing agent into the fabric body, resulting in uneven coating of the sizing agent inside the fabric body and affecting the final performance of the fabric body.

[0004] Therefore, in view of the problem that when sizing a fabric body with a relatively high yarn density, the sizing agent cannot evenly penetrate into the fabric body, resulting in uneven coating of the sizing agent inside the fabric body and affecting the final performance of the fabric body, a device for evenly sizing textile fabrics is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for evenly sizing textile fabrics to solve the problem that when sizing a fabric body with a relatively high yarn density, the sizing agent cannot evenly penetrate into the fabric body, resulting in uneven coating of the sizing agent inside the fabric body and affecting the final performance of the fabric body.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A uniform sizing device for textile fabrics, comprising a sizing bath, a driving roller, a motor, an upper squeegee and a lower squeegee. A plurality of driving rollers are rotatably connected in the sizing bath. The motor is installed on the outer side wall of the sizing bath. A plurality of the driving rollers are all connected to the motor. A fabric body rolls on the plurality of driving rollers. Both ends of the upper squeegee and the lower squeegee are connected to the inner wall of the sizing bath. The upper squeegee and the lower squeegee are respectively in contact with the upper and lower sides of the fabric body. A sizing assembly is arranged in the sizing bath. A suction cup is arranged on the sizing assembly. And the sizing agent in the sizing bath submerges the suction cup. The sizing assembly drives the driving roller through the motor to drive the suction cup to move towards the fabric body, and squeezes the sizing agent inside the suction cup into the fabric body through the pressure of the suction cup, avoiding the problem that when the uniform sizing device for textile fabrics sizes a fabric body with a high yarn density, the sizing agent cannot uniformly penetrate into the fabric body, resulting in uneven coating of the sizing agent inside the fabric body and affecting the final performance of the fabric body, and ensuring the uniformity during sizing of the uniform sizing device for textile fabrics.

[0008] Preferably, the sizing assembly includes a transmission group, a first crank and a first sizing plate. The transmission group is installed on the outer side wall of the sizing bath. The shaft ends of a plurality of the first cranks are rotatably connected to the inner side wall of the sizing bath. The connecting rod ends are respectively and pairwise rotatably connected to both ends of the first sizing plate. Both ends of the transmission group are respectively connected to the motor and the first crank. A plurality of the suction cups are all installed on the lower end surface of the first sizing plate. The openings of a plurality of the suction cups all point to the upper end surface of the fabric body, avoiding the problem that when a plurality of suction cups size the fabric body, the contact surfaces of the plurality of suction cups with the fabric body are not aligned, resulting in side leakage of the sizing agent extruded by the suction cups and the sizing agent not being completely extruded into the fabric body, and further resulting in uneven coating of the sizing agent inside the fabric body and affecting the final performance of the fabric body, and ensuring the uniformity during sizing of the uniform sizing device for textile fabrics.

[0009] Preferably, a plurality of second cranks and a plurality of second sizing plates are further provided in the sizing tank. The shaft ends of the plurality of second cranks are rotatably connected to the inner side wall of the sizing tank, and the connecting rod ends are rotatably connected to both ends of the second sizing plate in pairs. The first crank and the first sizing plate are both arranged above the fabric body, and the second crank and the second sizing plate are both arranged below the fabric body. The first crank and the second crank are meshed through a transmission wheel. A plurality of suction cups are also installed on the upper end surface of the second sizing plate, and the openings of the plurality of suction cups on the second sizing plate all point to the lower end surface of the fabric body. The plurality of suction cups on the second sizing plate and the plurality of suction cups on the first sizing plate are installed staggeredly, avoiding the problem that when the plurality of suction cups size the fabric body, one side of the fabric body is under pressure, resulting in side leakage of the sizing paste extruded by the suction cups and unable to be completely extruded into the fabric body, thereby causing uneven coating of the sizing paste inside the fabric body and affecting the final performance of the fabric body. This ensures the uniformity during sizing of the uniform sizing device for textile fabrics. At the same time, the staggered installation of the plurality of suction cups on the second sizing plate and the plurality of suction cups on the first sizing plate can improve the sizing efficiency of the uniform sizing device for textile fabrics.

[0010] Preferably, a connecting plate is installed at one end of the plurality of suction cups close to the fabric body, and the plurality of suction cups are all connected to the connecting plate. An anti-slip pad is installed at one end of the connecting plate close to the fabric body. The anti-slip pad is made of rubber material, and anti-slip lines are processed on one side of the anti-slip pad close to the fabric body. The anti-slip lines are in a grid shape, avoiding the problem that when the plurality of suction cups size the fabric body, relative displacement occurs between the fabric body and the plurality of suction cups, resulting in side leakage of the sizing paste extruded by the suction cups and unable to be completely extruded into the fabric body, thereby causing uneven coating of the sizing paste inside the fabric body and affecting the final performance of the fabric body. This ensures the uniformity during sizing of the uniform sizing device for textile fabrics. At the same time, the connecting plate connected to the plurality of suction cups can also avoid the problem that the sizing paste inside the fabric body is unevenly coated and the final performance of the fabric body is affected due to incomplete stretching of a single or multiple suction cups.

[0011] Preferably, a plurality of connecting grooves are formed at one end of the first sizing plate and the second sizing plate close to the fabric body. A plurality of connecting rods are installed at one end of the plurality of connecting plates away from the fabric body. The plurality of connecting rods are respectively slidably connected in the plurality of connecting grooves. A plurality of connecting springs are sleeved on the plurality of connecting rods, and both ends of the plurality of connecting springs are connected to the connecting plate and the first sizing plate or the second sizing plate respectively, avoiding the problem that when the plurality of suction cups size the fabric body, the contact pressure between the plurality of suction cups and the fabric body is insufficient, resulting in side leakage of the sizing paste during extrusion or back suction of the suction cups and unable to be completely extruded into the fabric body, thereby causing uneven coating of the sizing paste inside the fabric body and affecting the final performance of the fabric body. This ensures the uniformity during sizing of the uniform sizing device for textile fabrics.

[0012] Preferably, the driving wheels on the first crank and the second crank are in gear meshing. When the first crank and the second crank rotate, the rotational states of the connecting rod ends of the first crank and the second crank away from and close to the fabric are the same. The linear speeds of the first crank and the second crank driving the suction cup to rotate are the same as the linear speed of the transmission roller, avoiding the problem that when the first crank and the second crank rotate, different rotation angles result in different sizing times of the first sizing plate and the second sizing plate on the fabric, and further causing uneven sizing of the slurry inside the fabric body, which affects the final performance of the fabric body. This ensures the uniformity during sizing of the uniform sizing device for textile fabrics. And the linear speeds of the first crank and the second crank driving the suction cup to rotate are the same as the linear speed of the transmission roller, avoiding the problem that when the suction cup contacts the fabric body, relative displacement occurs between the suction cup and the fabric body, resulting in wear of the suction cup and the fabric body, and ensuring the service life of the uniform sizing device for textile fabrics.

[0013] Preferably, the suction cup is provided with a pre-pressing section, a stamping section, and a back-suction section. The pre-pressing section is the stage when the suction cup just contacts the fabric body. The stamping section is the stage when the suction cup squeezes the slurry into the fabric body after contacting the fabric body. The back-suction section is the stage when the suction cup gradually moves away from the fabric body after squeezing the slurry. Both the pre-pressing section and the back-suction section of the suction cup are assisted by the elastic force of the connecting spring to drive the suction cup to tightly adhere to the surface of the fabric body. The stamping section of the suction cup is driven by the pressure of the first sizing plate and the second sizing plate on the fabric body to squeeze the slurry inside the suction cup into the fabric body. At the same time, in the back-suction section, the suction cup generates negative pressure inside the suction cup through the elastic force of the connecting spring and itself, and attracts the slurry to pass through the fabric body and enter the suction cup, avoiding the problem that when the suction cup squeezes or back-sucks, the slurry leaks laterally and cannot be completely squeezed into the fabric body, resulting in uneven sizing of the slurry inside the fabric body and affecting the final performance of the fabric body, and ensuring the uniformity during sizing of the uniform sizing device for textile fabrics.

[0014] Preferably, a loosening elastic sheet is installed in each of the plurality of suction cups. The plurality of loosening elastic sheets are elastic elements. The plurality of loosening elastic sheets are installed in a C-shaped manner inside the suction cup, and the opening faces the fabric body side. Both ends of the loosening elastic sheet are connected to the inner side wall of the suction cup. A loosening groove is provided in each of the plurality of suction cups, and a loosening rod is slidably connected in each of the plurality of loosening grooves. The plurality of loosening rods are respectively connected to the middle parts of the plurality of loosening elastic sheets, avoiding the problem that when the plurality of suction cups size the fabric body, the yarns in some areas inside the fabric body are too tight, resulting in the slurry extruded by the suction cup not being completely squeezed into the fabric body in this area, and further causing uneven sizing of the slurry inside the fabric body and affecting the final performance of the fabric body, and ensuring the uniformity during sizing of the uniform sizing device for textile fabrics.

[0015] Preferably, a loosening grid is installed at one end of each of the plurality of loosening rods connected to the loosening elastic sheet. The plurality of loosening grids are all in a grid shape, which avoids the problem that when the loosening elastic sheet loosens the fabric body, the loosening elastic sheet cannot evenly disperse the elastic force to each position of the fabric body, resulting in a decrease in the loosening effect of the loosening elastic sheet. It ensures the loosening effect when the loosening elastic sheet of the textile fabric sizing device loosens the fabric, and at the same time, through the grid design of the loosening grid, the resistance when the loosening elastic sheet applies elastic force to the fabric body is reduced.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, a sizing component is provided in the sizing tank. A suction cup is provided on the sizing component, and the sizing material in the sizing tank submerges the suction cup. The sizing component drives a transmission roller through a motor to drive the suction cup to move towards the fabric body, and squeezes the sizing material inside the suction cup into the fabric body through the pressure of the suction cup, avoiding the problem that when the textile fabric sizing device sizes a fabric body with a high yarn density, the sizing material cannot evenly penetrate into the fabric body, resulting in uneven coating of the sizing material inside the fabric body and affecting the final performance of the fabric body, and ensuring the uniformity during sizing of the textile fabric sizing device.

[0018] 2. In the present invention, a plurality of second cranks and a plurality of second sizing plates are further provided in the sizing tank. The openings of the plurality of suction cups on the second sizing plates all point to the lower end surface of the fabric body. The plurality of suction cups on the second sizing plates and the plurality of suction cups on the first sizing plate are staggeredly installed, avoiding the problem that the fabric body is unilaterally pressured, resulting in side leakage of the sizing material, and further resulting in uneven coating of the sizing material inside the fabric body and affecting the final performance of the fabric body, ensuring the uniformity during sizing of the textile fabric sizing device. At the same time, the plurality of suction cups on the second sizing plate and the plurality of suction cups on the first sizing plate are staggeredly installed, which can improve the sizing efficiency of the sizing device.

[0019] 3. In the present invention, a plurality of connecting grooves are provided at one end of the first sizing plate and the second sizing plate close to the fabric body. A plurality of connecting rods are installed at one end of the plurality of connecting plates away from the fabric body. The plurality of connecting rods are respectively slidably connected in the plurality of connecting grooves, and connecting springs are sleeved on the plurality of connecting rods, avoiding the problem that when the plurality of suction cups size the fabric body, the contact pressure between the plurality of suction cups and the fabric body is insufficient, resulting in side leakage of the suction cups and being unable to be completely squeezed into the fabric body, and further resulting in uneven coating of the sizing material inside the fabric body and affecting the final performance of the fabric body, and further ensuring the uniformity during sizing of the textile fabric sizing device.

Detailed implementation manners

[0029] Please refer to Figures 1 to 8 , the present invention provides a uniform sizing device for textile fabrics, and the technical solution is as follows:

[0030] A uniform sizing device for textile fabrics, comprising a sizing bath 1, driving rollers 2, a motor 3, an upper squeegee 401 and a lower squeegee 402. A plurality of driving rollers 2 are rotatably connected inside the sizing bath 1. The motor 3 is installed on the outer side wall of the sizing bath 1. A plurality of driving rollers 2 are all connected to the motor 3. A fabric body 5 rolls on the plurality of driving rollers 2. Both ends of the upper squeegee 401 and the lower squeegee 402 are connected to the inner wall of the sizing bath 1. The upper squeegee 401 and the lower squeegee 402 are respectively in contact with the upper and lower sides of the fabric body 5. A sizing assembly is arranged inside the sizing bath 1. A suction cup 601 is arranged on the sizing assembly, and the sizing agent in the sizing bath submerges the suction cup 601. The sizing assembly drives the driving roller 2 through the motor 3 to drive the suction cup 601 to move towards the fabric body 5, and squeezes the sizing agent inside the suction cup 601 into the fabric body 5 through the pressure of the suction cup 601, avoiding the problem that when the uniform sizing device for textile fabrics sizes the fabric body 5 with a relatively high yarn density, the sizing agent cannot uniformly penetrate into the fabric body 5, resulting in uneven coating of the sizing agent inside the fabric body 5 and affecting the final performance of the fabric body 5, and ensuring the uniformity during sizing of the uniform sizing device for textile fabrics.

[0031] Please refer to Figures 1 to 8 , the sizing assembly includes a transmission group 602, a first crank 603 and a first sizing plate 604. The transmission group 602 is installed on the outer side wall of the sizing bath 1. The shaft ends of a plurality of first cranks 603 are rotatably connected to the inner side wall of the sizing bath 1. The connecting rod ends are respectively rotatably connected to both ends of the first sizing plate 604 in pairs. Both ends of the transmission group 602 are respectively connected to the motor 3 and the first crank 603. A plurality of suction cups 601 are all installed on the lower end surface of the first sizing plate 604. The openings of the plurality of suction cups 601 all point to the upper end surface of the fabric body 5. The plurality of suction cups 601 are uniformly installed on the first sizing plate 604. The first sizing plate 604 is pushed towards the fabric body 5 by rotating a plurality of cranks at the same angle, avoiding the problem that when a plurality of suction cups 601 size the fabric body 5, the contact surfaces of the plurality of suction cups 601 with the fabric body 5 are not aligned, resulting in side leakage of the sizing agent extruded by the suction cups 601 and the sizing agent not being completely squeezed into the fabric body 5, and further resulting in uneven coating of the sizing agent inside the fabric body 5 and affecting the final performance of the fabric body 5, and ensuring the uniformity during sizing of the uniform sizing device for textile fabrics.

[0032] It should be noted that there are also a plurality of second cranks 605 and a plurality of second sizing plates 606 provided in the sizing tank 1. The shaft ends of the plurality of second cranks 605 are rotatably connected to the inner side wall of the sizing tank 1, and the connecting rod ends are rotatably connected to both ends of the second sizing plate 606 in pairs. The first crank 603 and the first sizing plate 604 are both provided above the fabric body 5, and the second crank 605 and the second sizing plate 606 are both provided below the fabric body 5. The first crank 603 and the second crank 605 are meshed through a transmission wheel 607. A plurality of suction cups 601 are also installed on the upper end surface of the second sizing plate 606, and the openings of the plurality of suction cups 601 on the second sizing plate 606 all point to the lower end surface of the fabric body 5. The plurality of suction cups 601 on the second sizing plate 606 and the plurality of suction cups 601 on the first sizing plate 604 are installed staggeredly. A plurality of suction cups 601 are installed on both sides of the fabric body 5, and the pressure of the motor 3 is transmitted to the first sizing plate 604 and the second sizing plate 606 through the transmission wheel 607, driving the first sizing plate 604 and the second sizing plate 606 to apply pressure to the fabric body 5 at the same time, avoiding the problem that when the plurality of suction cups 601 size the fabric body 5, the fabric body 5 is unilaterally pressed, resulting in side leakage of the sizing paste extruded by the suction cups 601 and unable to be completely extruded into the fabric body 5, thereby causing uneven coating of the sizing paste inside the fabric body 5 and affecting the final performance of the fabric body 5. It ensures the uniformity during sizing of the uniform sizing device for textile fabrics. At the same time, the plurality of suction cups 601 on the second sizing plate 606 and the plurality of suction cups 601 on the first sizing plate 604 are installed staggeredly, which can also improve the sizing efficiency of the uniform sizing device for textile fabrics.

[0033] It is also worth noting that a connecting plate 701 is installed at one end of the plurality of suction cups 601 close to the fabric body 5, and the plurality of suction cups 601 are all connected to the connecting plate 701. An anti-slip pad 702 is installed at one end of the connecting plate 701 close to the fabric body 5. The anti-slip pad 702 is made of rubber material. Anti-slip lines 703 are processed on one side of the anti-slip pad 702 close to the fabric body 5. The anti-slip lines 703 are in a grid shape. When the suction cups 601 on both sides of the fabric body 5 come into contact with the fabric body 5 at the same time, the anti-slip pads 702 on the suction cups 601 on both sides of the fabric body 5 also come into contact and are pressed at the same time, avoiding the problem that when the plurality of suction cups 601 size the fabric body 5, relative displacement occurs between the fabric body 5 and the plurality of suction cups 601, resulting in side leakage of the sizing paste extruded by the suction cups 601 and unable to be completely extruded into the fabric body 5, thereby causing uneven coating of the sizing paste inside the fabric body 5 and affecting the final performance of the fabric body 5. It ensures the uniformity during sizing of the uniform sizing device for textile fabrics. At the same time, the connecting plate 701 connected to the plurality of suction cups 601 can also avoid the problem that uneven coating of the sizing paste inside the fabric body 5 and affecting the final performance of the fabric body 5 due to incomplete stretching of one or more suction cups 601.

[0034] A plurality of connecting grooves 704 are formed at one end of the first sizing plate 604 and the second sizing plate 606 close to the fabric body 5. A plurality of connecting rods 705 are installed at one end of the plurality of connecting plates 701 away from the fabric body 5. The plurality of connecting rods 705 are respectively slidably connected in the plurality of connecting grooves 704. A connecting spring 706 is sleeved on each of the plurality of connecting rods 705. Two ends of the plurality of connecting springs 706 are respectively connected to the connecting plate 701 and the first sizing plate 604 or the second sizing plate 606, which avoids the problem that when the plurality of suction cups 601 size the fabric body 5, the contact pressure between the plurality of suction cups 601 and the fabric body 5 is insufficient, resulting in side leakage of the sizing material when the suction cups 601 are squeezed or sucked back, and the sizing material cannot be completely squeezed into the fabric body 5, thereby causing uneven coating of the sizing material inside the fabric body 5 and affecting the final performance of the fabric body 5, and ensures the uniformity of sizing when the sizing device for textile fabrics is sizing.

[0035] The suction cup 601 is provided with a pre-pressing section, a stamping section and a suction-back section. The pre-pressing section is the stage when the suction cup 601 just contacts the fabric body 5. The stamping section is the stage when the suction cup 601 squeezes the sizing material into the fabric body 5 after contacting the fabric body 5. The suction-back section is the stage when the suction cup 601 gradually moves away from the fabric body 5 after squeezing the sizing material. The pre-pressing section and the suction-back section of the suction cup 601 are both assisted by the elastic force of the connecting spring 706 to drive the suction cup 601 to closely adhere to the surface of the fabric body 5. The stamping section of the suction cup 601 is driven by the pressure of the first sizing plate 604 and the second sizing plate 606 on the fabric body 5 to squeeze the sizing material inside the suction cup 601 into the fabric body 5. At the same time, in the suction-back section, the suction cup 601 generates negative pressure inside the suction cup 601 through the elastic force of the connecting spring 706 and itself, and attracts the sizing material to pass through the fabric body 5 and enter the suction cup 601, which avoids the problem that when the suction cup 601 is squeezed or sucked back, the sizing material leaks sideways and cannot be completely squeezed into the fabric body 5, resulting in uneven coating of the sizing material inside the fabric body 5 and affecting the final performance of the fabric body 5, and ensures the uniformity of sizing when the sizing device for textile fabrics is sizing.

[0036] Preferably, the transmission wheels 607 on the first crank 603 and the second crank 605 are in gear engagement. When the first crank 603 and the second crank 605 rotate, the rotational states of the connecting rod ends of the first crank 603 and the second crank 605 away from and close to the fabric are the same. The linear velocity of the first crank 603 and the second crank 605 driving the suction cup 601 to rotate is the same as the linear velocity of the transmission roller 2, avoiding the problem that when the first crank 603 and the second crank 605 rotate, different rotation angles result in different sizing times of the first sizing plate 604 and the second sizing plate 606 on the fabric, and further causing uneven sizing of the slurry inside the fabric body 5, which affects the final performance of the fabric body 5. This ensures the uniformity during sizing of the textile fabric uniform sizing device. And the linear velocity of the first crank 603 and the second crank 605 driving the suction cup 601 to rotate is the same as the linear velocity of the transmission roller 2, avoiding the problem of relative displacement between the suction cup 601 and the fabric body 5 when the suction cup 601 contacts the fabric body 5, resulting in wear of the suction cup 601 and the fabric body 5, and ensuring the service life of the textile fabric uniform sizing device.

[0037] Please refer to Figure 7 and Figure 8 , loose material elastic pieces 801 are installed in multiple suction cups 601. The multiple loose material elastic pieces 801 are elastic elements. The multiple loose material elastic pieces 801 are installed in a C shape inside the suction cup 601, and the opening faces the side of the fabric body 5. Both ends of the loose material elastic piece 801 are connected to the inner side wall of the suction cup 601. Loose material grooves 802 are opened in multiple suction cups 601. Loose material rods 803 are slidably connected in multiple loose material grooves 802. The multiple loose material rods 803 are respectively connected to the middle parts of the multiple loose material elastic pieces 801. When the multiple suction cups 601 move towards the fabric body 5, the suction cups 601 are gradually compressed and contracted. When the loose material rod 803 contacts the end of the loose material groove 802 away from the fabric body 5, the loose material elastic piece 801 is pushed by the force of the loose material rod 803 towards the fabric body 5. At this time, the midpoint of the C shape of the loose material elastic piece 801 is pressed, and the loose material elastic piece 801 gradually becomes straight. After the loose material elastic piece 801 is pressed into a straight line, the continuously pushed loose material rod 803 will trigger the loose material elastic piece 801 to quickly pop out towards the side of the fabric body 5, avoiding the problem that when the multiple suction cups 601 size the fabric body 5, the yarns in some areas inside the fabric body 5 are too tight, resulting in the slurry extruded by the suction cup 601 not being completely extruded into the inside of the fabric body 5 in this area, and further causing uneven sizing of the slurry inside the fabric body 5, which affects the final performance of the fabric body 5. This ensures the uniformity during sizing of the textile fabric uniform sizing device.

[0038] It should be noted that loose material gratings 804 are installed at one ends of multiple loose material rods 803 connected to the loose material elastic pieces 801. The multiple loose material gratings 804 are all in a grid shape. When the loose material elastic pieces 801 quickly pop out towards the fabric body 5, the elastic force on the loose material elastic pieces 801 will be applied to the loose material gratings 804 and evenly applied to each point of the fabric body 5 through the loose material gratings 804, avoiding the problem that when the loose material elastic pieces 801 loosen the fabric body 5, the loose material elastic pieces 801 cannot evenly disperse the elastic force to each position of the fabric body 5, resulting in a decrease in the loose material effect of the loose material elastic pieces 801, ensuring the loose material effect when the loose material elastic pieces 801 of the textile fabric sizing device loosen the material. At the same time, through the grid design of the gratings, the loose material gratings 804 reduce the resistance when the loose material elastic pieces 801 apply elastic force to the fabric body 5.

[0039] During operation, please refer to Figures 1 to 8, the motor 3 drives multiple transmission rollers 2 to rotate synchronously. The multiple transmission rollers 2 drive the fabric body 5 to move. At the same time, the motor 3 drives the first crank 603 to rotate by driving the transmission group 602. The first crank 603 makes the second crank 605 rotate in the reverse direction through the meshing transmission wheel 607. The rotation of the first crank 603 and the second crank 605 simultaneously drives the first sizing plate 604 and the second sizing plate 606 to move synchronously towards the fabric body 5. When the multiple suction cups 601 on the first sizing plate 604 and the second sizing plate 606 come into contact with the fabric body 5, the anti-slip pads 702 on the upper and lower sides of the multiple suction cups 601 contact each other. At this time, the suction cups 601 are in the pre-pressing section, avoiding the problem that the multiple suction cups 601 slide on the fabric body 5, resulting in the side leakage of the slurry extruded by the suction cups 601 and being unable to be completely extruded into the fabric body 5, thus causing uneven coating of the slurry inside the fabric body 5 and affecting the final performance of the fabric body 5. When the first sizing plate 604 and the second sizing plate 606 continue to move towards the fabric body 5, the multiple suction cups 601 on the upper and lower sides of the fabric body 5 are simultaneously pressed. At this time, the slurry inside the multiple suction cups 601 is pressed and penetrates into the fabric body 5, and passes through the whole fabric body 5 and flows out from the other side of the fabric body 5. At this time, the suction cups 601 are in the stamping section, avoiding the problem that when the sizing device for textile fabrics sizes the fabric body 5 with a higher yarn density, the slurry cannot penetrate evenly into the fabric body 5, resulting in uneven coating of the slurry inside the fabric body 5 and affecting the final performance of the fabric body 5. Further, the first crank 603 and the second crank 605 drive the first sizing plate 604 and the second sizing plate 606 to move towards the side away from the fabric body 5. At this time, the suction cups 601 are in the re-suction section. The suction cups 601 make the side close to the fabric body 5 of the multiple suction cups 601 closely contact the fabric body 5 through the elastic force of the connecting spring 706. When the first sizing plate 604 and the second sizing plate 606 gradually move towards the side away from the fabric body 5, a negative pressure will be generated inside the multiple suction cups 601. This negative pressure attracts the slurry on the other side of the fabric body 5 to pass through the fabric body 5 and enter the suction cups 601, further improving the uniformity during sizing of the sizing device for textile fabrics.

[0040] It should be noted that when multiple suction cups 601 move towards the fabric body 5 in the stamping section, the suction cups 601 are gradually compressed and contracted. When the material loosening rod 803 contacts the end of the material loosening groove 802 away from the fabric body 5, the material loosening elastic piece 801 is pushed by the force of the material loosening rod 803 towards the fabric body 5. At this time, the midpoint of the C-shaped material loosening elastic piece 801 is compressed, and the material loosening elastic piece 801 gradually becomes straight. After the material loosening elastic piece 801 is compressed into a straight line, the continuously pushed material loosening rod 803 will trigger the material loosening elastic piece 801 to quickly pop out towards the fabric body 5 side, avoiding the problem that when multiple suction cups 601 apply sizing to the fabric body 5, the yarns in some areas inside the fabric body 5 are too tight, resulting in the sizing extruded by the suction cups 601 not being completely extruded into the inside of the fabric body 5 in this area, and further causing uneven coating of the sizing inside the fabric body 5 and affecting the final performance of the fabric body 5.

[0041] It is also worth noting that when the material loosening elastic piece 801 quickly pops out towards the fabric body 5 side, the elastic force on the material loosening elastic piece 801 will be applied to the material loosening grid 804 and evenly applied to each point of the fabric body 5 through the material loosening grid 804, avoiding the problem that when the material loosening elastic piece 801 loosens the fabric body 5, the material loosening elastic piece 801 cannot evenly disperse the elastic force to each position of the fabric body 5, resulting in a decrease in the material loosening effect of the material loosening elastic piece 801. At the same time, through the grid mesh design of the material loosening grid 804, the resistance when the material loosening elastic piece 801 applies elastic force to the fabric body 5 is reduced.

[0042] The above has described in detail a specific implementation manner of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described implementation manner. For those skilled in the art, without departing from the principles and ideas of the present invention, various changes, modifications, substitutions, and variations made to these implementation manners should still fall within the protection scope of the present invention.
