[0002] Space mesh fabric, also known as hollow mesh fabric, has been continuously updated and iterated since the invention of warp knitting machines. Space mesh fabric is a typical product of warp knitting machines. Its unique three-dimensional structure with double-layer fabric surfaces embedded with wire drawing can be applied to many specific products, which makes space mesh fabric very popular in the market. When processing space mesh fabric, space mesh fabric processing equipment is needed to facilitate subsequent further processing operations on the space mesh fabric.

[0003] When processing space mesh fabric, space mesh fabric processing equipment is needed. Among them, the "warp knitting space mesh fabric double-sided variable weft density mechanism" disclosed in the patent with the publication number of "CN217438401U" has solved various drawbacks that the mesh fabric cannot be processed into a specific curvature.

[0004] However, there are still many defects in the actual use of space mesh fabric processing equipment with similar structures, such as: in the prior art, the device for changing the weft density of space mesh fabric has a complex structure, requires operators to interfere with the weft density operation, increases the work intensity of the operators, reduces the automation effect of the device, reduces the efficiency of changing the weft density of space mesh fabric, and is not convenient for the device to be popularized and used. Therefore, a warp knitting space mesh fabric double-sided variable weft density mechanism is proposed. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a warp knitting space mesh fabric double-sided variable weft density mechanism to solve the above problems.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: a warp knitting space mesh fabric double-sided variable weft density mechanism, including a carrier, on one side of the top of the carrier, a driving mechanism for changing the weft density of the space mesh fabric is fixedly installed, and on one side of the driving mechanism, a deformation prevention mechanism is fixedly installed;

[0007] The driving mechanism includes two groups of mounting frames. On the top of one side of the mounting frame, a first motor is fixedly installed.

On one side of the first transmission mechanism, a second motor for providing a power source for the lower roller is fixedly installed. At the bottom of the back of the mounting frame, a second transmission mechanism is fixedly installed, and on one side of the second transmission mechanism, a planetary reducer for adjusting the rotation speed of the lower roller is fixedly installed;

[0008] The anti-deformation mechanism comprises a hollow seat, and a shell is fixedly installed on the top of the hollow seat.

[0011] Preferably, a fixing frame is fixedly mounted on one side of the anti-deformation mechanism, and a winding roller is rotatably mounted inside the fixing frame.

[0012] Preferably, a fixing seat is fixedly mounted on the top of the carrier away from the anti-deformation mechanism, a uniform speed motor is fixedly mounted on one side of the fixing seat, and a discharge roller is fixedly mounted on the output end of the uniform speed motor.

[0014] Beneficial Effects

[0015] The utility model provides a double-sided variable weft density mechanism for warp knitted space mesh fabric. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The upper roller is driven to rotate by energizing the first motor, and the first transmission mechanism is driven to rotate by energizing the second motor. The rotating first transmission mechanism can drive the lower roller to rotate, and the rotating lower roller can drive the second transmission mechanism to rotate. The rotation speed of the second transmission mechanism can be limited by the preset value of the planetary reducer, so that there is a rotation speed difference between the lower roller and the upper roller. The space mesh cloth is pulled to move its position by an external winding device. The two groups of rollers with different rotation speeds can push the internal fibers of the space mesh cloth, so that the density of the fibers on both sides of the space mesh cloth is different, and the function of automatically changing the weft density of the space mesh cloth is realized. The device has the characteristics of simple structure and high reliability, effectively reduces the economic expenditure on changing the weft density of the space mesh cloth, improves the efficiency of changing the weft density of the space mesh cloth, shortens the time for processing the changing weft density of the space mesh cloth, and is convenient for the popularization and use of the device.

[0017] 2. After being connected to the external atomizing equipment through the nozzle, the atomized water source can be transported to the inside of the shell, and then the heating wire is energized to generate heat and heat the atomized water source, so that the heated water source is vaporized into high-temperature steam and transported to the surface of the space mesh through the slot for ironing operation. In addition, the function of preventing the space mesh from being deformed is achieved by cooperating with the resistance roller, thereby avoiding the deformation of the space mesh caused by heat during the subsequent further processing of the space mesh, and reducing the effect of unified specifications of the subsequent finished space mesh products.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1-4 , the utility model provides two technical solutions:

[0025] The first embodiment: a double-sided weft density changing mechanism for a warp knitted space mesh cloth, comprising a carrier 1, a driving mechanism 2 for changing the weft density of the space mesh cloth is fixedly installed on one side of the top of the carrier 1, and an anti-deformation mechanism 4 is fixedly installed on one side of the driving mechanism 2;

[0026] The driving mechanism 2 includes two sets of mounting brackets 201. At the top of one side of the mounting bracket 201, a first motor 202 is fixedly installed. At the output end of the first motor 202, an upper roller 203 is fixedly installed. At the bottom inside the mounting bracket 201, a lower roller 204 is rotatably installed. At the bottom of the front of the mounting bracket 201, a first transmission mechanism 205 is fixedly installed, and the first transmission mechanism 205 is fixedly connected to one side of the lower roller 204. On one side of the first transmission mechanism 205, a second motor 206 for providing a power source for the lower roller 204 is fixedly installed. At the bottom of the back of the mounting bracket 201, a second transmission mechanism 207 is fixedly installed, and on one side of the second transmission mechanism 207, a planetary reducer 208 for adjusting the rotation speed of the lower roller 204 is fixedly installed;

[0027] The anti-deformation mechanism 4 includes a hollow seat 401. At the top inside the hollow seat 401, a housing 402 is fixedly installed. At the bottom of the anti-deformation mechanism 4, a support frame 3 is fixedly installed, and the bottom of the support frame 3 is fixedly connected to one side of the top of the carrier 1;

[0028] On one side of the anti-deformation mechanism 4, a fixed frame 5 is fixedly installed. Inside the fixed frame 5, a winding roller 501 is rotatably installed. On one side of the top of the carrier 1 away from the anti-deformation mechanism 4, a fixed seat 6 is fixedly installed. On one side of the fixed seat 6, a constant-speed motor 601 is fixedly installed, and at the output end of the constant-speed motor 601, a feeding roller 602 is fixedly installed.

[0029] By energizing and operating the constant-speed motor 601 to drive the feeding roller 602 to rotate, the space fabric can be fed through the rotating feeding roller 602, facilitating subsequent processing operations on the space fabric. The support frame 3 can provide an installation position for the anti-deformation mechanism 4, ensuring the stable installation position of the anti-deformation mechanism 4;

[0030] By energizing and operating the first motor 202 to drive the upper roller 203 to rotate, and then by energizing and operating the second motor 206, the first transmission mechanism 205 can be driven to rotate. The rotating first transmission mechanism 205 can drive the lower roller 204 to rotate;

[0031] The rotating lower roller 204 can drive the second transmission mechanism 207 to rotate. Then, the preset value of the planetary reducer 208 can limit the rotation speed of the second transmission mechanism 207, so that there is a rotation speed difference between the lower roller 204 and the upper roller 203. Then, the space fabric is pulled by an external winding device to move its position. The two rollers with different rotation speeds can push the fibers inside the space fabric, making the fiber tightness on both sides of the space fabric different, realizing the function of automatically changing the weft density of the space fabric.

[0032] The fixing bracket 5 provides a placement position for the winding roller 501. The cooperation of the fixing bracket 5 and the winding roller 501 facilitates the winding operation of the space fabric. At the same time, the open structure on one side of the fixing bracket 5 facilitates the separation of the winding roller 501 from the inside of the fixing bracket 5, providing convenience for replacing the winding roller 501.

[0033] The second embodiment is mainly different from the first embodiment in that: a protective box 7 is fixedly installed outside the constant-speed motor 601, and one side of the protective box 7 is fixedly connected to one side of the fixed seat 6; the top inside the housing 402 is equidistantly installed with coiled spray pipes 403, the bottom inside the housing 402 is equidistantly installed with heating wires 404 that cooperate with the spray pipes 403, the bottom inside the housing 402 is equidistantly provided with slot holes 405, and two sets of abutting rollers 406 are rotatably installed outside the housing 402.

[0034] The protective box 7 provides an installation position for the constant-speed motor 601, ensuring the stable effect of the installation position of the constant-speed motor 601 and preventing the constant-speed motor 601 from falling off its installation position due to external impacts on the device;

[0035] After the spray pipes 403 are connected to an external atomization device, the atomized water source can be transported into the housing 402. Then, the heating wires 404 are energized to generate heat and heat the atomized water source, so that the heated water source is vaporized into high-temperature steam and transported to the surface of the space fabric through the slot holes 405 for ironing operations, and the function of preventing the deformation of the space fabric is achieved by cooperating with the abutting rollers 406.

[0036] At the same time, the content not described in detail in this specification belongs to the well-known prior art in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.
