[0001] The invention relates to the technical field of automatic cloth-pulling machines, and in particular to an automatic cloth-pulling machine with a tensioning self-adjusting function. Background Art

[0002] Since most fabrics are produced and transported in rolls, an important step in processing the fabrics in the factory is to turn the rolled materials into a multi-layer flat state so that they can be easily cut and used. Therefore, an automatic fabric stretching machine is needed to stretch and lay the fabrics.

[0003] However, due to differences in factors such as fabric material and thickness, as well as improper tension control of the fabric pulling machine, the fabric may easily become unevenly tensioned during the pulling process, resulting in inaccurate fabric size after cutting, affecting product quality and consistency. Excessive or uneven tension may damage the fabric, affecting its quality and service life. When there is a problem with the tension of the fabric, manual adjustment is usually required. Frequent manual adjustments and fabric damage will lead to production interruptions, affecting production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] Based on the problem that the cloth tension of the existing cloth stretching machine needs to be adjusted manually, which reduces the production efficiency and even causes cloth damage, this embodiment provides an automatic cloth stretching machine with a tension self-adjusting function, please refer to Figure 1-Figure 6 The embodiment provides an automatic cloth-pulling machine with a tension self-adjusting function, which can automatically adjust the tension of the cloth to avoid damage to the cloth. The automatic cloth-pulling machine with a tension self-adjusting function includes a cloth-pulling machine 2 installed on a cloth-laying table 1, and a tension adjustment mechanism 3 for adjusting the tension of the cloth is provided on the cloth-pulling machine 2. The tension of the cloth is automatically adjusted by the tension adjustment mechanism 3 when the cloth-pulling machine 2 is laying the cloth, without manual adjustment, which is more convenient and quick, and better protects the cloth.

[0032] Since the cloth tension of the existing cloth pulling machine needs to be adjusted manually, which reduces the production efficiency and even causes cloth damage, the device is provided with a tensioning adjustment mechanism 3, which includes an electric telescopic rod 301 installed on the cloth pulling machine 2, and a U-shaped frame 302 is installed at the free end of the electric telescopic rod 301. A tensioning roller 303 is rotatably connected inside the U-shaped frame 302, and a self-adjusting component 304 for automatically adjusting the cloth tension is provided between the electric telescopic rod 301 and the U-shaped frame 302, and a static electricity elimination component 305 for eliminating static electricity on the cloth is provided on the tensioning roller 303.

[0033] The self-adjusting component 304 includes a sleeve 3041 installed at the free end of the electric telescopic rod 301, a flexible spring 3042 is installed in the sleeve 3041, and a slider 3043 slidably connected to the inner wall of the sleeve 3041 is installed at the other end of the flexible spring 3042, a slide bar 3044 slidably connected to the sleeve 3041 is installed on the slider 3043, and the top of the slide bar 3044 is connected to the U-shaped frame 302. First, the electric telescopic rod 301 is started to push the U-shaped frame 302 up until the tension roller 303 rotating inside it fits the surface of the fabric, and as the U-shaped frame 302 continues to move, the tension roller 303 rotates in the U-shaped frame 302. The sliding rod 3044 rises, and the sliding rod 3044 is squeezed to slide toward the inside of the sliding sleeve 3041 and slightly compress the flexible spring 3042, thereby providing initial tension for the cloth laying process. When the cloth is being laid, if the cloth becomes slightly loose, the pressure on the flexible spring 3042 becomes smaller, thereby releasing a certain elastic force. When the cloth is too tight, the flexible spring 3042 continues to be compressed under pressure, thereby utilizing the elasticity of the flexible spring 3042 to adaptively adjust the tension of the cloth, thereby better protecting the cloth, and eliminating the need for repeated stops to adjust the tension of the cloth by manpower, thereby improving production efficiency.

[0034] When the fabric is too loose or too tight and reaches the adaptive adjustment limit value of the self-adjusting component 304, the device symmetrically installs electric contacts 3045 located in the flexible spring 3042 on the bottom wall of the sleeve 3041 and the slider 3043, and symmetrically installs electric contact rings 3046 in the installation grooves opened on the top of the slider 3043 and the top wall of the sleeve 3041. When the fabric is too tight, the pressing slide bar 3044 pushes the slider 3043 to compress the flexible spring 3042 to the limit value. At this time, the electric contacts 3045 on the bottom wall of the sleeve 3041 and the slider 3043 contact and send out an electrical signal, sounding an alarm to remind the worker to readjust the tension through the electric telescopic rod 301 in time. When the fabric is too loose and the tensioning roller 303 cannot fit the fabric, the elasticity of the flexible spring 3042 is completely released, so that the two electric contact rings 3046 contact and send out corresponding alarms, which is convenient for the worker to make timely adjustments.

[0035] Since some fabric materials may have a certain amount of static electricity, when the fabric is stretched and laid, it will cause adhesion between the fabrics, affecting subsequent processing. Therefore, the device is also provided with a static electricity elimination component 305, and the static electricity elimination component 305 includes an installation bin 3051 opened in the tensioning roller 303, and a static electricity eliminator 3052 is installed in the installation bin 3051. The tensioning roller 303 is provided with an electromagnetic ring sleeve 3053, and the electromagnetic ring sleeve 3053 is electrically connected to the static electricity eliminator 3052. A gathering component 306 for gathering the fabric is provided on the electromagnetic ring sleeve 3053, and a dust removal component 307 for removing impurities adsorbed by static electricity on the electromagnetic ring sleeve 3053 is provided on the outer side of the electromagnetic ring sleeve 3053. When the tensioning roller 303 rotates to discharge the material, the static electricity eliminator 3052 is started, and the static electricity on the fabric is eliminated through the electromagnetic ring sleeve 3053 electrically connected to it and sleeved on the tensioning roller 303, so as to avoid the subsequent fabric adhesion.

[0036] Since the cloth may tilt or even detach from the tensioning roller 303 when it is stretched and laid, the device is provided with a gathering component 306, which includes a T-shaped slide groove 3061 symmetrically arranged on both sides of the electromagnetic ring sleeve 3053 with equal distances around the center of the end face thereof, a T-shaped slider 3062 is slidably connected in the T-shaped slide groove 3061 and is interlocked with the T-shaped slide groove 3061, a gathering bar 3063 is installed on the outer side of the T-shaped slider 3062, and a connecting bar 3064 attached to the surface of the electromagnetic ring sleeve 3053 is installed between the two groups of gathering bars 3063.

[0037] The T-shaped slide groove 3061, the T-shaped slider 3062 and the pulling bar 3063 are all V-shaped structures, and the T-shaped slider 3062 and the pulling bar 3063 are all made of flexible rubber material. The pulling bar 3063, which is symmetrically installed on both sides of the tensioning roller 303 through the V-shaped structure, generates an inward centripetal force when the tensioning roller 303 rotates, thereby driving the cloth to gather and center on the tensioning roller 303, avoiding the cloth from escaping from the tensioning roller 303, and the T-shaped slide groove 3061 and the T-shaped slider 3062 are interlocked with each other, so that it is easier to replace the pulling bar 3063 or replace it with a brush to adapt to different cloth pulling situations.

[0038] Electric guide rails 4 are installed on the front and rear sides of the cloth spreading table 1. A guide rail groove that interlocks with the electric guide rails 4 is provided at the bottom of the cloth spreading machine 2. The cloth spreading machine 2 cooperates with the electric guide rails 4 to achieve left and right movement of the cloth spreading machine 2 to spread the cloth. An electric control box 5 is installed on the cloth spreading machine 2. The tension adjustment mechanism 3 and the electric guide rails 4 are electrically connected to the electric control box 5. The normal operation of the device is controlled by the electric control box 5.

[0039] Example 2

[0040] On the basis of Example 1, Figure 1-Figure 6As shown, when the static electricity elimination component 305 eliminates the static electricity on the cloth, the static magnetic field generated by itself will also absorb some impurities on the cloth, and as the impurities accumulate and wrap the electromagnetic ring sleeve 3053, it will affect the effect of static electricity elimination. Therefore, the device is also provided with a dust removal component 307, which includes a brush 3071 rotatably connected to the U-shaped frame 302 and located below the electromagnetic ring sleeve 3053, a side baffle 3072 is installed on the U-shaped frame 302, and a cloth spreading table 1 is installed. A vacuum cleaner 3073, the suction port of the vacuum cleaner 3073 is installed with a connecting pipe 3074, the top of the connecting pipe 3074 is installed with a dust suction pipe 3075, and the dust suction pipe 3075 extends into the inner side of the side baffle 3072. As the tensioning roller 303 drives the electromagnetic ring sleeve 3053 to rotate, the brush 3071 is driven to rotate, so that the impurities on the surface of the electromagnetic ring sleeve 3053 are brushed off by the brush 3071, and then the vacuum cleaner 3073 is started to suck away the brushed dust through the connecting pipe 3074 and the dust suction pipe 3075.
