[0002] Cotton fabric is a woven fabric made from cotton yarn. Different varieties are derived from different weave specifications and post-processing methods. Cotton fabric is characterized by its softness and comfort, warmth, moisture absorption, breathability, and ease of dyeing and finishing. Due to these natural properties, it has long been loved by people and has become an indispensable basic necessity in life. Cotton fabric is a necessity in people's daily lives, with wide applications in clothing, bedding, home furnishings, and interior decoration. It also has extensive applications in packaging, industry, medicine, and the military. The production and processing of cotton fabric involves cutting processes. For example, after the cotton fabric is rolled or coiled to a certain size, it needs to be cut. Cutting cotton fabric into pieces of a certain area for subsequent processes also requires cutting. General cutting equipment uses conveyor rollers for transport. During the cutting process, the cotton fabric needs to be kept under tight pressure; otherwise, the cotton fabric may not be in close contact with the conveyor roller, resulting in idle rotation. Therefore, a cutting device for cotton fabric production is proposed to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the embodiments, by Figure 1-5 A cutting device for cotton fabric production is provided, comprising a machine body 1, a drive shaft 2 rotatably connected to the inner side of the machine body 1, an active roller 3 fixedly connected to the outer side of the drive shaft 2, resistance-increasing grooves 9 provided on the outer side of the active roller 3, a drive mechanism 4 for driving the drive shaft 2 installed at the bottom end of the machine body 1, a pressing mechanism 5 for pressing the cotton fabric on the machine body 1, and a cutting mechanism 6 for cutting the cotton fabric on the machine body 1.

[0026] The pressing mechanism 5 includes guide blocks 51. Four guide blocks 51 are fixedly connected to the inner side of the machine body 1. Bearing seats 52 are slidably connected between two adjacent guide blocks 51 on the left and right sides. A rotating shaft 53 is rotatably connected between two bearing seats 52. A pressing roller 54 is fixedly connected to the outer side of the rotating shaft 53. A slide groove 55 is provided on the machine body 1. The rotating shaft 53 is slidably connected to the inner side of the slide groove 55.

[0027] With the above setup, one end of the cotton cloth is first passed between the pressing roller 54 and the drive roller 3, and then through the cutting mechanism 6. Since the pressing roller 54 has its own weight, and the bearing seat 52 slides between the two guide blocks 51, the pressing roller 54 can press the cotton cloth tightly between the pressing roller 54 and the drive roller 3. The drive mechanism 4 is started, and the drive shaft 2 is driven to rotate through the drive mechanism 4, thereby driving the drive roller 3 to rotate. Due to the action of the resistance-increasing groove 9, the cotton cloth will be transmitted backward under the action of friction as the drive roller 3 rotates. Then, the cotton cloth is cut by the cutting mechanism 6.

[0028] Reference Figure 1-5 The machine body 1 is also equipped with an adjustment mechanism 7 for adjusting the relative distance between the drive roller 3 and the pressing roller 54;

[0029] With the above-mentioned structural configuration, the adjustment mechanism 7 can adjust the relative distance between the drive roller 3 and the pressure roller 54 to adapt to the cutting of cotton fabrics of different thicknesses.

[0030] Reference Figure 1-5 The adjustment mechanism 7 includes an adjustment cylinder 71. The adjustment cylinder 71 is fixedly connected to the inner side of the body 1. An adjustment cylinder push rod 72 is slidably connected to the inner side of the adjustment cylinder 71. A U-shaped lifting plate 73 is fixedly connected to the top of the adjustment cylinder push rod 72. The U-shaped lifting plate 73 is fixed to the bottom of the two bearing seats 52 respectively. Two U-shaped grooves 74 are opened on the U-shaped lifting plate 73. The drive shaft 2 is located inside the two U-shaped grooves 74.

[0031] With the above-described structure, the adjusting cylinder 71 is activated, which drives the adjusting cylinder push rod 72 to move upward or retract downward, thereby driving the U-shaped lifting plate 73 to move upward or retract downward. The U-shaped lifting plate 73 is fixed to the bottom ends of the two bearing seats 52 respectively. Therefore, the two bearing seats 52 move upward or retract downward, thereby adjusting the relative distance between the drive roller 3 and the pressing roller 54.

[0032] Reference Figure 1-5 In this case, gears 8 are fixedly connected to the outer sides of both the drive shaft 2 and the rotating shaft 53, and the two gears 8 mesh with each other;

[0033] With the above structural configuration, the drive shaft 2 can drive the rotating shaft 53 to rotate through the transmission of gear 8, thereby improving the effect of transmitting cotton cloth.

[0034] Reference Figure 1-5 The drive mechanism 4 includes a mounting plate 41. The bottom end of the body 1 is fixedly connected to the mounting plate 41. The right end of the mounting plate 41 is fixedly connected to the drive motor 42. The output end of the drive motor 42 is fixedly connected to the transmission mechanism 43. The transmission mechanism 43 is fixedly connected to the outside of the drive shaft 2.

[0035] With the above structural setup, the drive motor 42 is started, and the power generated by the drive motor 42 is transmitted to the drive shaft 2 through the transmission mechanism 43. It should be noted that the transmission mechanism 43 can be either a belt pulley transmission mechanism or a chain sprocket transmission mechanism.

[0036] Reference Figure 1-5 The cutting mechanism 6 includes a cutting cylinder 61. The cutting cylinder 61 is fixedly connected to the top of the machine body 1. A cutting cylinder push rod 62 is slidably connected to the inner side of the cutting cylinder 61. An upper knife holder 63 is fixedly connected to the outer side of the cutting cylinder push rod 62. An upper knife 64 is fixedly connected to the upper knife holder 63. A lower knife holder 65 is fixedly connected to the machine body 1. Two guide pillars 66 are fixedly connected to the inner side of the machine body 1. The upper knife holder 63 is slidably connected to the outer side of the two guide pillars 66. Two pressing guide pillars 67 are slidably connected to the inner side of the upper knife holder 63. A spring is provided at the top of each of the two pressing guide pillars 67. The bottom of each of the two pressing guide pillars 67 is fixedly connected to a pressing plate 68.

[0037] With the above structural setup, the cutting cylinder 61 is activated, which drives the cutting cylinder push rod 62 to extend. The upper blade holder 63 slides downward along the outer side of the two guide pillars 66, thereby driving the upper blade 64, the two pressing guide pillars 67, and the pressing plate 68 to move downward. After the pressing plate 68 presses down on the cotton cloth (to prevent the cotton cloth from shifting during the cutting process and affecting the cutting effect), the upper blade 64 continues to move downward. At this time, the spring gradually contracts until the upper blade 64, together with the lower blade holder 65, cuts the cotton cloth. The cutting cylinder push rod 62 is then controlled to contract, and the upper blade holder 63 slides upward along the outer side of the two guide pillars 66, thereby driving the upper blade 64, the two pressing guide pillars 67, and the pressing plate 68 to move upward. The spring gradually returns to its initial state, and finally the upper blade 64, the two pressing guide pillars 67, and the pressing plate 68 all return to their original positions.
