Description

Technical Field

[0001] This utility model relates to the field of webbing processing technology, specifically a high-precision webbing slitting device. Background Technology

[0002] Ribbons are narrow strips of flexible fabric made from natural fibers, synthetic fibers, or high-performance composite yarns through weaving, knitting, or machine weaving processes.

[0003] As a basic industrial material, webbing has formed a diversified application system due to its high strength, wear resistance, and high plasticity: in the field of people's livelihood, it is widely used in daily life scenarios such as clothing accessories, shoe reinforcement, and bag handles; in the industrial field, it is used in load-bearing components such as automotive seat belt core materials, engineering hoisting belts, and agricultural machinery transmission belts; in the special field, it serves precision scenarios such as military equipment carrying gear, spacecraft restraint devices, and medical polymer bandages.

[0004] In actual processing, the webbing produced by the braiding machine is usually a very wide and long strip, which needs to be cut in the length or width direction. As described in the published patent CN222412386U, in some uses of webbing, it is necessary to cut the webbing into specific lengths. However, since the webbing itself is soft, it is easy for the webbing to shift during cutting, resulting in incorrect cutting dimensions and waste products.

[0005] In summary, during the length-direction slitting process of webbing, especially for highly elastic webbing, the webbing itself is prone to deformation, which can lead to dimensional deviations and affect the slitting quality. Utility Model Content

Detailed Implementation

[0037] 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.

[0038] Please see Figure 1-11 A high-precision webbing slitting device includes a base 101, and a feeding component 102, a guiding component 103, a marking component 104, a straightening component 105 and a cutting component 106 are arranged sequentially from front to back along the longitudinal direction above the base 101.

[0039] The feeding assembly 102 includes a feeding plate 107 fixed on the base 101, and a feeding roller 108 is rotatably mounted on the feeding plate 107.

[0040] The material guiding assembly 103 includes a material guiding plate 109 fixed on the base 101, and a plurality of material guiding rollers 110 are rotatably arranged on the material guiding plate 109 from front to back.

[0041] A slitting frame 111 is fixed on the base 101. The marking assembly 104 includes a marking guide rail 112 fixed laterally on the slitting frame 111 and a marking material roller 113 rotatably mounted laterally on the slitting frame 111. A plurality of laser marking heads 114 are equidistantly arranged on the packaging guide rail. The marking material roller 113 is located below the laser marking heads 114.

[0042] The material preparation assembly 105 includes a first tensioning assembly 115 and a second tensioning assembly 116 arranged sequentially from front to back on the slitting frame 111. The first tensioning assembly 115 includes a first tensioning shaft 117 and a first support roller 118 that are laterally rotatably arranged on the slitting frame 111. The first tensioning shaft 117 is provided with a plurality of first tensioning wheels 119 that are mutually clamped and cooperated with the first support roller 118 at equal intervals. The second tensioning assembly 116 includes a second tensioning shaft 120 and a second support roller 121 that are laterally rotatably arranged on the slitting frame 111. The second tensioning shaft 120 is provided with a plurality of second tensioning wheels 122 that are mutually clamped and cooperated with the second support roller 121 at equal intervals.

[0043] The cutting component 106 is disposed between the first tensioning component 115 and the second tensioning component 116. The cutting component 106 includes a first cutting shaft 123 and a second cutting shaft 124 that are laterally rotatably disposed on the cutting frame 111. A plurality of first ring cutting blade groups 125 are fixedly fixed at equal intervals on the first cutting shaft 123, and a plurality of second ring cutting blade groups 126 that are aligned and cooperate with the first ring cutting blade groups 125 are fixedly fixedly at equal intervals on the second cutting shaft 124.

[0044] like Figure 1 As shown, during the use of the high-precision webbing slitting device of this utility model, the first tensioning shaft 117 and the second tensioning shaft 120 are rotated and adjusted by external power components, the first slitting shaft 123 and the first slitting shaft 123 are rotated and adjusted by external power components, and a take-up roller is provided at the rear of the slitting device for taking up the webbing.

[0045] First, the tension-adjustable feeding roller 108 of the feeding assembly 102 achieves uniform release of the webbing. Combined with the multi-stage guide roller 110 of the guide assembly 103, which adopts a high-low staggered arrangement design, it reduces the friction on the surface of the webbing and forms a progressive guide path, avoiding lateral deviation of the webbing due to inertia or external disturbances during the conveying process.

[0046] The marking assembly 104 forms micron-level positioning marks with programmable spacing on the surface of the webbing through closed-loop synchronous control of the marking roller 113 driven by the servo motor and the laser marking head 114. During the marking process, the roller and the laser are matched in real time.

[0047] The integral material assembly 105 adopts a differentiated two-stage tensioning strategy. The first tensioning assembly 115 forms a clamping structure with the first tensioning roller 119 and the first support roller 118 to apply clamping force to the webbing. The second tensioning assembly 116 forms a clamping structure with the second tensioning roller 122 and the second support roller 121. The first tensioning assembly 115 and the second tensioning assembly 116 apply "differential" tensioning to the webbing, applying dynamic tension to the webbing before slitting, forming a prestress equilibrium state of the elastic webbing, and suppressing the slitting offset caused by the elastic deformation of the material during slitting.

[0048] The "differential" tensioning specifically means that when the first tensioning shaft 117 rotates at speed A and the second tensioning shaft 120 rotates at speed B, there will be a speed difference between the first tensioning assembly 115 and the second tensioning assembly 116. Due to the existence of the speed difference, the elastic webbing is tensioned between the first tensioning assembly 115 and the second tensioning assembly 116.

[0049] The cutting component 106 adopts dual-axis servo linkage technology. The first cutting axis 123 and the second cutting axis 124 achieve reverse synchronous rotation through a gearbox. Under the laser positioning mark, the tensioned elastic webbing is cut according to the laser positioning mark, so it is suitable for cutting different elastic webbing and different tension. No matter how elastic the elastic webbing is, or how much tension is between the first tensioning component 115 and the second tensioning component 116, the position to be cut can always be accurately located by the laser positioning mark. It is especially suitable for high elastic webbing containing composite yarns.

[0050] Each component achieves action timing optimization through a central controller, and parameters such as the linear speed of the guide roller 110, marking interval, tension shaft pressure, and slitting shaft torque form a closed-loop feedback;

[0051] This utility model's high-precision webbing slitting device achieves precise slitting through the coordinated operation of streamlined components. The feeding component 102 uses an adjustable feeding roller 108 to ensure uniform webbing supply. The guiding component 103 employs multi-stage guiding rollers 110 to reduce conveying friction. The marking component 104 uses a laser marking head 114 in conjunction with a synchronously rotating marking roller 113 to form precise positioning marks on the webbing surface. The straightening component 105 uses a first tensioning component 115 and a second tensioning component 116 to form a dynamic tension balance, effectively suppressing the elastic deformation of the elastic webbing during slitting and reducing slitting offset caused by elastic deformation. The cutting component 106 is equipped with a dual-axis linkage ring cutting system, where the first ring cutting blade group 125 and the second ring cutting blade group 126 form an interlaced shearing structure, achieving high-precision synchronous cutting at the laser positioning mark.

[0052] In this embodiment of the utility model, the outer side of the slitting frame 111 is provided with a first tensioning gear 127 fixedly connected to the first tensioning shaft 117 and a second tensioning gear 128 fixedly connected to the first support roller 118. The second tensioning gear 128 meshes with the first tensioning gear 127 for transmission, and the second gear is connected to an external power component for transmission.

[0053] The outer side of the slitting frame 111 is provided with a third tensioning gear 129 fixedly connected to the second tensioning shaft 120 and a fourth tensioning gear 130 fixedly connected to the second support roller 121. The fourth tensioning gear 130 meshes with the third tensioning gear 129 for transmission, and the fourth gear is connected to an external power component for transmission.

[0054] The outer side of the slitting frame 111 is provided with a first slitting gear 131 fixedly connected to the first slitting shaft 123 and a second slitting gear 132 fixedly connected to the second slitting shaft 124. The second slitting gear 132 meshes with the first slitting gear 131 for transmission, and the second slitting component is connected to an external power component for transmission.

[0055] like Figure 1 and 2 As shown, this utility model achieves power coordination between the tensioning and cutting components 106 through a gear meshing transmission system. Multiple sets of gear components are provided on the outside of the cutting frame 111 and are fixedly connected to the tensioning shaft, the support roller and the cutting shaft respectively. The first tensioning gear meshes with the second tensioning gear to drive the first tensioning component 115 to form a rotational clamp, and the third tensioning gear meshes with the fourth tensioning gear to drive the second tensioning component 116 to apply force synchronously.

[0056] All gears are driven by the same external power source, and the power is evenly distributed to each execution unit through meshing transmission. This ensures that the pressure applied by the tensioning cam to the webbing, the rotation feedback of the support roller, and the cutting action of the ring cutter group are strictly synchronized. This avoids the accumulation of local deformation caused by the delay in power transmission during the slitting process, thereby ensuring the dynamic coordination between tensioning and precise cutting at the mechanical structure level, and significantly improving the stability of the slitting process and the consistency of products.

[0057] In this embodiment of the present invention, the first tensioning component 115 and the second tensioning component 116 are arranged on the cutting frame 111 in an inclined upward manner, the cutting component 106 is located at the middle position of the inclined line connecting the first tensioning component 115 and the second tensioning component 116, an auxiliary roller 134 is provided between the first tensioning component 115 and the second tensioning component 116, and the first tensioning component 115, the auxiliary roller 134 and the second tensioning component 116 are arranged in a "F" shape.

[0058] like Figure 3 and 4As shown in the figure, the utility model improves the slitting stability by optimizing the spatial layout of the tensioning component and the cutting component 106: First, the auxiliary roller 134 and the second tensioning component 116 are distributed in the slitting frame 111 in an inclined upward manner, forming a "factory"-shaped tension buffer belt for the webbing conveying path, so that the webbing before slitting is evenly stretched under inclined traction and forms a directional pre-tightening force. The cutting component 106 is precisely arranged at the middle balance position of the connection line of the two obliquely arranged tensioning components, and uses the symmetric transmission of the tension on both sides to offset the impact vibration during cutting; the inclined layout decomposes and releases the clamping force of the tensioning cam on the webbing obliquely, which not only avoids fiber damage caused by vertical pressure, but also realizes the gradient neutralization of elastic deformation through the spatial dislocation design of the cutting point and the tensioning point, ensuring that the webbing is always in a dynamic balance state during the cutting process, so as to maintain the incision flatness and dimensional accuracy under complex slitting conditions.

[0059] In the embodiment of the utility model, the first circumferential cutting knife group 125 includes a first knife seat 135 sleeved on the first slitting shaft 123. A blade installation groove 136 is opened on the outer wall of the first knife seat 135, and a circumferential cutting blade 137 is installed in the blade installation groove 136. A plurality of locking installation grooves 138 are evenly opened in the circumferential direction on the inner ring of the first knife seat 135. Locking connecting rods 139 are respectively installed in the plurality of locking installation grooves 138. The plurality of locking connecting rods 139 are evenly surrounded and abutted against the first slitting shaft 123. One end of the locking connecting rod 139 is rotatably connected in the locking installation groove 138 and obliquely contracts towards the other end. A locking ring 140 is sleeved on the other end of the locking connecting rod 139, and the locking ring 140 is screwed with the locking connecting rod 139;

[0060] As Figure 10 shown in the figure, the utility model realizes the rapid and precise adjustment of the circumferential cutting knife group through a modular blade locking structure: The circumferential locking installation groove 138 provided on the first knife seat 135 cooperates with the obliquely contracting locking connecting rod 139. When the locking ring 140 is rotated, it drives the locking connecting rod 139 to generate a gradually tightening contraction force in the circumferential direction, so that the locking connecting rod 139 is evenly pressed and fixed along the circumferential direction of the first slitting shaft 123;

[0061] This design allows for fine adjustment of the blade tightness by rotating the locking ring 140 during the non-stop state.配合刀片安装槽136的定向定位功能,既可快速更换不同规格刀片以适应分切需求,又能确保刀片与分切轴的同心度,使环切过程中刀刃受力分布均匀,有效防止因刀片偏摆或松动引发的切口毛刺或纤维层错位问题,显著提升裁切稳定性和设备维护效率。With the directional positioning function of the blade installation groove 136, different specifications of blades can be quickly replaced to meet the slitting requirements, and the concentricity between the blade and the slitting shaft can be ensured, so that the force distribution of the cutting edge is uniform during the circumferential cutting process, effectively preventing problems such as incision burrs or fiber layer misalignment caused by blade deflection or loosening, and significantly improving the cutting stability and equipment maintenance efficiency.

[0062] In this embodiment of the present invention, the second ring cutter assembly 126 includes a second cutter holder 141 sleeved on the second cutting shaft 124. The outer wall of the second cutter holder 141 is provided with a cutting receiving groove 142 that aligns with the ring cutter blade 137. The upper end of the second cutter holder 141 aligns with the upper end of the first cutter holder 135. The upper end of the second cutter holder 141 is provided with an arc-shaped guide surface 143. The inner bottom surface of the cutting receiving groove 142 is provided with a through bolt mounting hole 144.

[0063] like Figure 11 As shown, the cutting receiving groove 142 of the second blade holder 141 and the first ring cutting blade 137 form a precise nested cutting space, which, together with the upper end alignment design, realizes the dynamic self-calibration of the double blade group to ensure cutting accuracy.

[0064] The arc-shaped guide surface 143 guides the fiber layer to be smoothly introduced into the shearing zone in the early stage of contact between the second cutter holder 141 and the webbing. At the same time, after the ring cutter 137 and the cutting groove 142 cut the material, the arc-shaped guide surface 143 can make the cut surface slide out smoothly, making the operation process more stable.

[0065] The bolt mounting holes 144 at the bottom of the cutting receiving groove 142 achieve rigid locking between the second blade holder 141 and the second cutting shaft 124 through modular connection. While maintaining high cutting accuracy, it allows for quick disassembly and maintenance. The overall design, through geometrically adapted cutting space, progressive guide surface and detachable fixing structure, improves the stability of the blade assembly and reduces the blade wear rate, significantly extending the continuous cutting life of the equipment.

[0066] In this embodiment of the present invention, the slitting frame 111 is symmetrically arranged on the left and right sides. The first lifting adjustment component 145 is symmetrically fixed on the inner wall of the slitting frame 111. The first lifting adjustment component 145 includes a first lifting adjustment frame 146, a first lifting cylinder component 147, and a first lifting slider 148. The first lifting adjustment frame 146 is fixed on the inner wall of the slitting frame 111. The first lifting cylinder component 147 is fixed on the upper end of the first lifting adjustment frame 146. The first lifting slider 148 is slidably disposed in the first lifting adjustment frame 146 and fixedly connected to the working shaft of the first lifting cylinder component 147. The first lifting slider 148 is slidably connected to the inner walls on both sides of the first lifting adjustment frame 146. The end of the first slitting shaft 123 is fixed on the first lifting slider 148.

[0067] like Figure 6As shown, the symmetrical layout of the slitting frame 111 and the mirror distribution of the first lifting adjustment component 145 form a bidirectional balanced support structure. The first lifting cylinder drives the first lifting slider 148 to slide vertically along the inner wall of the adjustment frame, thereby achieving stepless adjustment of the slitting axis height while suppressing lateral offset. This not only adapts to the slitting depth requirements of webbing of different thicknesses, but also increases operational stability through the synchronous action of the symmetrical cylinders.

[0068] In this embodiment of the present invention, a flattening component 149 is further provided between the marking component 104 and the material preparation component 105. The flattening component 149 includes a second lifting adjustment component 150 fixed on the inner wall of the cutting frame 111. The second lifting adjustment component 150 includes a second lifting adjustment frame 151, a second lifting cylinder component 152, and a second lifting slider 153. The second lifting adjustment frame 151 is fixed on the inner wall of the cutting frame 111, the second lifting cylinder component 152 is fixed on the upper end of the lifting adjustment frame, and the second lifting slider 153 is slidably disposed in the second lifting adjustment frame 151 and fixedly connected to the working shaft of the second lifting cylinder component 152. The second lifting slider 153 is slidably connected to the inner walls on both sides of the second lifting adjustment frame 151. A first flattening roller 154 is fixed on the second lifting slider 153, and a second flattening roller 155 that abuts against and cooperates with the first flattening roller 154 is fixed on the cutting frame 111.

[0069] This invention optimizes the flatness and slitting quality of the webbing through dynamic pressure control of the flattening component 149. The second lifting adjustment component 150 added between the marking and finishing components 105 drives the first flattening roller 154 to rise and fall vertically through a cylinder-driven slider, forming an adjustable gap elastic clamping area with the fixed second flattening roller 155. This allows for adaptive adjustment of the roller pressure gap according to the webbing thickness, and also guides the webbing to smoothly transition to the finishing station through the double roller curved surface contact.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
