Description

Technical Field

[0001] This utility model relates to the field of chemical fiber raw material processing, and in particular to a chemical fiber raw material flattening device to prevent edge wrinkling. Background Technology

[0002] The core value of preventing wrinkling and flattening the edges of synthetic fiber raw materials lies in ensuring product quality, reducing raw material waste, improving production efficiency, and meeting high-end demands. Wrinkling leads to dimensional deviations and surface defects, causing product downgrading or scrapping; wrinkles force an increase in edge width of 20%-50%, resulting in annual waste costs exceeding one million yuan; at the same time, wrinkles easily cause equipment jams, increase cleaning frequency, and limit production line speed by 30%. In addition, stress concentration at wrinkles accelerates aging, and rough edges may cause equipment roller entanglement or electrostatic fires. Especially for high-end applications that require "zero-wrinkle edges," flattening can increase raw material utilization by more than 15% and reduce scrap rate by 50%, resulting in significant overall efficiency gains.

[0003] Existing devices often suffer from residual stress in the chemical fiber raw materials during the previous winding process before cutting. This stress can cause wavy wrinkles during subsequent unwinding, and uneven tension during transport can lead to localized arching, resulting in dimensional deviations in the subsequent cutting. Furthermore, the internal stress inherent in the raw materials is released during cutting, causing a sudden change in stress distribution at the cut point, which can lead to edge shrinkage or warping. Therefore, a chemical fiber raw material flattening device to prevent edge wrinkling is proposed to solve the above problems. Utility Model Content

A second transmission belt is driven to the other end of the shaft of the first roller. A second roller is driven to the inner wall of the second transmission belt.

[0007] As a further description of the above technical solution: the anti-wrinkle mechanism includes a first electric push rod, which is fixedly connected to the inner wall of the machine body.

[0026] Reference Figure 1As shown, one embodiment of this utility model is provided: a chemical fiber raw material flattening device to prevent edge wrinkling, including a machine body 1, with a feed inlet on the left side and a discharge outlet on the right side. A sliding groove 43 is provided on the inner wall of the machine body 1. A cutting roller 2 is rotatably connected to the inner wall of the machine body 1. The cutting roller 2 can cut the chemical fiber raw material and provide power to the flattening mechanism 3. The flattening mechanism 3 is provided on the outer wall of the cutting roller 2. The flattening mechanism 3 can eliminate wrinkles in the raw material and achieve flattening, thereby improving the subsequent cutting efficiency. An anti-wrinkle mechanism 4 is provided on the inner wall of the machine body 1. The anti-wrinkle mechanism 4 squeezes the edge of the raw material by pressing the pressure block to prevent wrinkling during processing.

[0027] Reference Figures 2-4 As shown, the flattening mechanism 3 includes a support 31, which can fix and support the roller of the flattening mechanism 3. The support 31 is fixedly connected to the outer wall of the machine body 1. A first bevel gear 38 is fixedly connected to the outer wall of the cutting roller 2. The first bevel gear 38 transmits the power of the cutting roller 2 to a second bevel gear 37. The first bevel gear 38 meshes with the second bevel gear 37. The second bevel gear 37 is rotatably connected to the inner wall of the support 31. The meshing of the second bevel gear 37 with the first bevel gear 38 changes the direction of power transmission. A connecting rod 36 is fixedly connected to the center of the inner wall of the second bevel gear 37. The connecting rod 36 can transmit the power of the bevel gear to the first transmission belt 34. The outer wall of the connecting rod 36 is connected to the first transmission belt 34. The first transmission belt 34 can transmit power from the connecting rod 36 to the first roller 35. The inner wall of the first transmission belt 34 is connected to the first transmission belt 35. There is a first roller 35, and two sets of first rollers 35 are provided. The two sets of first rollers 35 are connected by a cross drive belt 33. The first rollers 35 and the second rollers 32 are rotatably connected to the inner wall of the support 31. The first rollers 35 achieve bidirectional stretching and flattening of the raw materials through cross drive. The cross drive belt 33 is connected to the rotating shaft of the first rollers 35. The cross drive belt 33 can connect the two sets of first rollers 35 to achieve reverse rotation and enhance the flattening effect. The other end of the rotating shaft of the first rollers 35 is connected to a second drive belt 39. The second drive belt 39 can connect the first rollers 35 and the second rollers 32 to achieve synchronous drive. The inner wall of the second drive belt 39 is connected to a second roller 32. Two sets of second rollers 32 are provided. The second rollers 32 can cooperate with the first rollers 35 to flatten the raw materials and eliminate wrinkles.

[0028] Reference Figures 5-6As shown, the anti-crease mechanism 4 includes a first electric push rod 41, which can drive a first connecting block 42 to move a first pressure block 47 to adjust the pressure. The first electric push rod 41 is fixedly connected to the inner wall of the body 1, and the first connecting block 42 is fixedly connected to the outer wall of the first electric push rod 41. The first connecting block 42 and the second connecting block 44 are slidably connected in the slide groove 43. The first connecting block 42 connects the first electric push rod 41 and the first pressure block 47 to transmit driving force. The first pressure block 47 is fixedly connected to the side wall of the first connecting block 42. The first pressure block 47 and the second pressure block 46 are arranged in a transverse V-shape. The second pressure block 46 forms a V-shaped extrusion fit, allowing the raw material to pass through the V-shaped opening until it exits, eliminating residual wrinkles after cutting. The inner wall of the machine body 1 is fixedly connected to a second electric push rod 45, which can drive the second connecting block 44 to move the second pressure block 46 and adjust the pressure. The outer wall of the second electric push rod 45 is fixedly connected to a second connecting block 44, which connects the second electric push rod 45 and the second pressure block 46 to transmit driving force. The side wall of the second connecting block 44 is fixedly connected to a second pressure block 46, which cooperates with the first pressure block 47 to extrude and cut the raw material, eliminating wrinkles caused by cutting.

[0029] In use, the cutting roller 2 is powered by the first bevel gear 38 and the second bevel gear 37, and driven by the connecting rod 36 through the first transmission belt 34 to rotate the first roller 35. Then, the cross transmission belt 33 drives the two sets of first rollers 35 to rotate in opposite directions, forming a bidirectional stretching of the raw material. The second transmission belt 39 is linked with the second roller 32 to operate synchronously, working with the first roller 35 to stretch the raw material and eliminate wrinkles on the raw material.

[0030] To eliminate wrinkles caused by cutting, the first connecting block 42 and the second connecting block 44 are driven to slide along the slide groove 43 by the first electric push rod 41 and the second electric push rod 45 respectively. This causes the first pressing block 47 and the second pressing block 46 to move closer together, and the two pressing blocks form a V-shaped extrusion structure. Stable pressure is applied from both sides of the raw material edge to avoid new wrinkles after cutting and to ensure that the raw material is flat when entering the next process.
