Description

Technical Field

[0001] This utility model relates to the field of chemical fiber production, and in particular to a rapid cutting device for chemical fiber production. Background Technology

[0002] Chemical fibers are fibers with textile properties produced by using natural or artificially synthesized polymers as raw materials, through processes such as preparing spinning solutions, spinning, and post-treatment. Processed chemical fibers are widely used in clothing, furniture, and industrial fields due to their advantages such as high strength, good abrasion resistance, excellent wrinkle resistance, strong dimensional stability, and relatively low price. After production, chemical fibers need to be cut to the required size to facilitate further embellishment and decoration.

[0003] To address this issue, Chinese Patent Publication No. CN219213346U discloses a rapid cutting device for chemical fiber production, comprising a cutting table. Support legs are welded to the four corners of the bottom of the cutting table, and a support platform is welded to the top of the front surface of each support leg. An automatic conveying device is installed on the top of the support platform. First support plates are fixedly connected to the left and right sides of the top of the cutting table. A rectangular slide rod is fixedly connected to the top of the inner side of the first support plate. A slider is movably fitted around the outer ring of the rectangular slide rod, and a first bolt is provided on the top of the slider. This invention solves the problems of fixed cutting blades (only one blade), which prevents blade adjustment based on the required carpet area and blade spacing for cutting multiple carpets at once, resulting in low production efficiency. Furthermore, cutting after pressing and fixing the carpet can lead to the carpet becoming immobile, requiring manual adjustment and causing cumbersome operation.

[0004] Although the aforementioned patent allows for adjustment of the spacing between the blades, this adjustment requires manual adjustment. This manual operation can lead to errors in the spacing, resulting in dimensional errors in the final cut carpet and ultimately wasting materials. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this device provides a rapid cutting device for chemical fiber production. This device can more accurately adjust the spacing between each cutting blade, and at the same time, it presses the carpet during cutting to prevent the carpet from slipping and shifting, thereby improving the accuracy of the carpet's dimensions after cutting.

[0006] The purpose of this utility model is to provide a rapid cutting device for chemical fiber production, including a cutting table, support legs fixedly connected to the four corners of the bottom of the cutting table, a gantry frame fixedly connected to the top of the cutting table body, a first electric push rod fixedly connected to the bottom of the gantry frame, a cutting mechanism fixedly connected to the extended end of the first electric push rod, a plurality of cutting blades with adjustable spacing slidably connected laterally to the bottom of the cutting mechanism, pressing mechanisms fixedly connected to both sides of the gantry frame, and a traction mechanism for traction of carpet fixedly connected to the front end of the top of the cutting table.

[0007] Furthermore, the cutting mechanism includes a lifting block, the top of which is fixedly connected to the bottom of the extended end of the first electric push rod. A transverse slide rail is fixedly connected to the front end of the lifting block, and multiple moving blocks are slidably connected to the surface of the transverse slide rail. Cutting blades are threadedly connected to the bottom of each moving block. An adjustment frame is vertically slidably connected to the front end of the lifting block, and multiple adjustment slots are radially distributed through the surface of the adjustment frame. Pins are fixedly connected to the front ends of the moving blocks, and the pins are slidably connected to the corresponding adjustment slots. A second electric push rod for adjusting the lifting height of the adjustment frame is fixedly connected to the rear end of the adjustment frame. The extended end of the second electric push rod is fixedly connected to the upper surface of the rear end of the adjustment frame, and the fixed end of the second electric push rod is fixedly connected to the top of the rear end of the lifting block.

[0008] Furthermore, the pressing mechanism includes a pressing roller, with longitudinal sliders rotatably connected to both ends of the pressing roller. Fixed blocks are fixedly connected to both sides of the top of the cutting table. Longitudinal grooves are opened on the inner side of the fixed blocks. The longitudinal sliders at both ends of the pressing roller are slidably connected in the corresponding longitudinal grooves. Springs are fixedly connected between the longitudinal grooves and the longitudinal sliders.

[0009] Furthermore, a limiting shaft is vertically fixedly connected inside the longitudinal slide groove. The limiting shaft is slidably connected to the fixed block. A spring is sleeved on the radial surface of the limiting shaft. The top end of the spring is fixedly connected to the top end of the longitudinal slide groove, and the bottom end of the spring is fixedly connected to the upper surface of the cutting table.

[0010] Furthermore, the traction mechanism includes two longitudinally distributed traction rollers. The two ends of the two traction rollers are rotatably connected to baffles fixedly connected to both sides of the top of the cutting table. One end of the two traction rollers passes through one of the baffles and is coaxially fixedly connected to a first spur gear and a second spur gear. The first spur gear and the second spur gear mesh with each other. A drive motor is fixedly connected to the top of the cutting table on the same side as the first spur gear and the second spur gear. The output end of the drive motor is coaxially fixedly connected to the second spur gear.

[0011] Furthermore, the top of the lifting block is fixedly connected to two symmetrically arranged stabilizing shafts, which are splinedly connected to the gantry frame.

[0012] The working principle and usage principle of this utility model are as follows: First, the pressing rollers on the front and rear sides of the gantry frame are lifted upwards, and the carpet is placed on the upper surface of the cutting table. The pressing mechanism is used to press the carpet downwards onto the cutting table surface to prevent the carpet from sliding. The cutting blade is brought into contact with the carpet by the control of the first electric push rod. Then, one end of the carpet is placed between the two traction rollers. The carpet is moved by the rotation of the two traction rollers. During the movement of the carpet, the cutting blade cuts the carpet. When it is necessary to adjust the spacing between multiple cutting blades, the second electric push rod is used to control the adjustment frame to move upwards along the lifting block. At this time, the pins at the front ends of multiple moving blocks move from the top end of the adjustment groove to the bottom end of the adjustment groove. At this time, the horizontal slide rail is used to control the multiple moving blocks to synchronously shrink the spacing, thereby realizing the adjustment of the cutting blade spacing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Compared with the prior art, the present invention can control multiple cutting blades to adjust their spacing synchronously through the cutting mechanism, making the distance between the cutting blades more accurate when adjusting the spacing, avoiding the errors caused by manual spacing adjustment, and avoiding errors in carpet cutting dimensions.

[0015] 2. Compared with the prior art, this utility model allows the carpet to move above the cutting table through the cooperation of the pressing mechanism and the traction mechanism, and at the same time, the carpet can be pressed, so as to avoid the carpet displacement during cutting and affect the carpet segment cutting effect.

[0022] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0023] according to Figures 1 to 5 As shown, a rapid cutting device for chemical fiber production includes a cutting table 1, with support legs fixedly connected to the four corners of the bottom of the cutting table 1, a gantry frame 2 fixedly connected to the top of the cutting table 1, a first electric push rod 7 fixedly connected to the bottom of the gantry frame 2, a cutting mechanism 3 fixedly connected to the extended end of the first electric push rod 7, and multiple cutting blades 6 with adjustable spacing slidably connected laterally to the bottom of the cutting mechanism 3, pressing mechanisms 4 fixedly connected to both sides of the gantry frame 2, and a traction mechanism 5 for traction of carpet fixedly connected to the front end of the top of the cutting table 1.

[0024] In practice, the entire carpet can be placed on the upper surface of the cutting table 1. At this time, the pressing mechanism 4 can press the carpet, and the traction mechanism 5 can pull the carpet from back to front. Under the control of the first electric push rod 7, the cutting mechanism lowers its height so that the cutting blade 6 contacts the carpet surface. Then, under the traction of the traction mechanism 5, the carpet is cut into sections. At the same time, the spacing between multiple cutting blades 6 can be controlled synchronously through the cutting mechanism 3, avoiding the problem of inconsistent section sizes caused by manually adjusting the cutting blades 6.

[0025] Furthermore, the cutting mechanism 3 includes a lifting block 31. The top of the lifting block 31 is fixedly connected to the bottom of the extended end of the first electric push rod 7. A transverse slide rail 33 is fixedly connected to the front end of the lifting block 31. Multiple moving blocks 34 are slidably connected to the surface of the transverse slide rail 33. Cutting blades 6 are threadedly connected to the bottom of each moving block 34. An adjustment frame 32 is vertically slidably connected to the front end of the lifting block 31. Multiple adjustment slots 36 are opened through the surface of the adjustment frame 32 and are radially distributed. Pins 35 are fixedly connected to the front ends of the moving blocks 34 and are slidably connected to the corresponding adjustment slots 36. A second electric push rod 37 for adjusting the lifting height of the adjustment frame 32 is fixedly connected to the rear end of the adjustment frame 32. The extended end of the second electric push rod 37 is fixedly connected to the upper surface of the rear end of the adjustment frame 32, and the fixed end of the second electric push rod 37 is fixedly connected to the top of the rear end of the lifting block 31.

[0026] In practical implementation, the second electric push rod 37 can control the adjusting frame 32 to slide up and down along the lifting block 31. Multiple radially arranged adjusting slots 36 are distributed radially around a central adjusting slot 36. The top and bottom ends of the multiple adjusting slots 36 are equidistant, but the distance between the top ends is greater than the distance between the bottom ends. When it is necessary to reduce the distance between the multiple cutting blades 6, the second electric push rod 37 controls the adjusting frame 32 to move upward along the lifting block 31. The pins 35 at the front ends of the multiple moving blocks 34 move from the top to the bottom of the adjusting slot 36. When the pins 35 move within the adjusting slot 36, the multiple moving blocks 34 move laterally. The slide rail 33 slides laterally left and right to reduce the gap. The reduction in the gap between the moving blocks 34 leads to the adjustment of the gap between the bottom cutting blades 6. Conversely, when the second electric push rod 37 controls the adjustment frame 32 to move downward along the lifting block 31, the pins 35 at the front end of the multiple moving blocks 34 move from the bottom end to the top end of the adjustment groove 36. When the pins 35 move in the adjustment groove 36, the multiple moving blocks 34 slide laterally left and right on the surface of the slide rail 33 to increase the gap. The increase in the gap between the moving blocks 34 leads to the adjustment of the gap between the bottom cutting blades 6, so as to achieve more precise adjustment of the gap between each cutting blade 6.

[0027] Furthermore, the pressing mechanism 4 includes a pressing roller 41, with longitudinal sliders 42 rotatably connected to both ends of the pressing roller 41. Fixing blocks 43 are fixedly connected to both sides of the top of the cutting table 1. A longitudinal groove 46 is provided on the inner side of the fixing block 43. The longitudinal sliders 42 at both ends of the pressing roller 41 are slidably connected in the corresponding longitudinal grooves 46. A spring 45 is fixedly connected between the longitudinal grooves 46 and the longitudinal sliders 42.

[0028] In practice, the longitudinal sliders 42 at both ends of the pressing roller 41 are slidably connected to the longitudinal grooves 46 opened in the corresponding fixed blocks 43. The spring 45 at the top of the longitudinal slider 42 applies a downward elastic force to the longitudinal slider 42. The friction between the carpet and the surface of the pressing roller 41 can make the pressing roller 41 rotate. At the same time, the downward elastic force applied by the spring 45 drives the pressing roller 41 to fit tightly with the carpet to press the carpet downward, thus preventing the carpet from slipping when it moves forward.

[0029] Furthermore, a limiting shaft 44 is vertically fixedly connected inside the longitudinal slide groove 46. The limiting shaft 44 is slidably connected to the fixing block 43. A spring 45 is sleeved on the radial surface of the limiting shaft 44. The top end of the spring 45 is fixedly connected to the top end of the longitudinal slide groove 46, and the bottom end of the spring 45 is fixedly connected to the upper surface of the cutting table 1.

[0030] In practical implementation, the limiting shaft 44 is longitudinally arranged between the fixed block 43 and the cutting table 1, and the longitudinal slider 42 is provided with limiting holes that slide with the limiting shaft 44. The setting of the limiting shaft 44 and the limiting holes restricts the downward movement direction of the longitudinal slider 42, avoiding the problem of displacement of the pressing roller 41 caused by the displacement of the longitudinal slider 42 when the spring 45 applies a downward elastic force to the longitudinal slider 42.

[0031] Furthermore, the traction mechanism 5 includes two longitudinally distributed traction rollers 51. The two ends of the two traction rollers 51 are rotatably connected to baffles 52 fixedly connected to the top of the cutting table 1 on both sides. One end of the two traction rollers 51 passes through one of the baffles 52 and is coaxially fixedly connected to a first spur gear 53 and a second spur gear 54. The first spur gear 53 and the second spur gear 54 mesh with each other. A drive motor 55 is fixedly connected to the top of the cutting table 1 on the same side as the first spur gear 53 and the second spur gear 54. The output end of the drive motor 55 is coaxially fixedly connected to the second spur gear 54.

[0032] In practice, the carpet passes through the gap between the two traction rollers 51. One end of the two traction rollers 51, which are positioned vertically, is controlled by the first spur gear 53 and the second spur gear 54 to rotate. When the drive motor 55 controls the second spur gear 54 to rotate, the second spur gear 54 drives the first spur gear 53 to rotate. In turn, the rotation of the first spur gear 53 and the second spur gear 54 drives the two traction rollers 51 to rotate axially. When the two traction rollers 51 rotate, the friction generated when the traction rollers 51 contact the upper and lower surfaces of the carpet causes the carpet to be pulled forward. At the same time, in order to increase the friction between the traction rollers 51 and the carpet, the surfaces of the two traction rollers 51 can be set with elastic anti-slip pads. The anti-slip pads increase the friction between the traction rollers 51 and the carpet, and the elastic anti-slip pads can meet the traction requirements of carpets of various thicknesses.

[0033] Furthermore, the top of the lifting block 31 is fixedly connected to two symmetrically arranged stabilizing shafts 8, and the stabilizing shafts 8 are splinedly connected to the gantry frame 2.

[0034] In practical implementation, two stabilizing shafts 8 are fixedly connected to the top of the lifting block 31, and the top ends of the two stabilizing shafts 8 pass through the gantry frame 2. The stability of the lifting block 31 during lifting is achieved through the spline connection between the two stabilizing shafts 8 and the gantry frame 2. This avoids the difference in cutting depth of the left and right cutting blades 6 caused by the inconsistent horizontal height of the left and right ends of the lifting block 31 during lifting, which would prevent the carpet from being cut and divided in one go, thus improving the cutting effect of the cutting blades 6 on the carpet.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
