Detailed Implementation

[0031] 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.

[0032] Please see Figure 1-7 A multifunctional blade head structure for webbing includes a mounting roller 101. Multiple blade head assemblies 102 are equidistantly arranged on the mounting roller 101. Each blade head assembly 102 includes an annular mounting seat 103 fixedly mounted on the mounting roller 101. An upwardly protruding mounting side plate 104 is formed on the annular mounting seat 103. A first annular member 105 and a second annular member 106 are sleeved on the annular mounting seat 103. The first annular member 105 is fixedly mounted on the annular mounting seat 103. An annular mounting groove 107 is formed between the first annular member 105 and the mounting side plate 104. The second annular member 106 rotates within the annular mounting groove 107.

[0033] An auxiliary side plate 108 is formed protruding downward on the first annular part 105, and a cutter head mounting plate 109 is formed protruding downward on the second annular part 106. A cutter head mounting position 110 is formed between the auxiliary side plate 108 and the cutter head mounting plate 109.

[0034] A heating element 111 is fixedly mounted on the cutting head mounting plate 109, and a cutting head 112 is fixedly mounted on the side wall of the heating element 111.

[0035] A pressure plate 113 is fixedly provided on the lower end face of the auxiliary side plate 108. A cutter head mounting groove 114 is provided on the pressure plate 113, and the cutter head 112 extends downward from the cutter head mounting groove 114.

[0036] The upper end of the mounting side plate 104 is equipped with a telescopic component 115. The upper end of the telescopic component 115 is rotatably engaged on the mounting side plate 104. The working shaft of the telescopic component 115 is rotatably connected to the cutter head mounting plate 109.

[0037] This utility model arranges multiple independent cutter head assemblies 102 at equal intervals on the mounting roller 101. Each assembly is modularly assembled through the nesting structure of the annular mounting base 103 and the first and second annular parts 106, making independent adjustment of the cutter head more convenient.

[0038] The fixed fit between the first annular component 105 and the annular mounting base 103 forms a rigid support base. The rotational freedom of the second annular component 106 within the annular mounting groove 107 allows the cutter head component 112 to dynamically adjust its angle around the axis of the mounting roller 101. Combined with the real-time adjustment of the cutter head mounting plate 109 by the telescopic component 115, the cutting parameters can be precisely adapted to webbing of different materials and thicknesses, significantly improving the flexibility and adaptability of the slitting process.

[0039] Traditional melting and cutting processes are prone to molten material sticking to the cutter head due to uneven temperature conduction or excessive contact between the cutter head and the webbing. By having the cutter head 112 adhere to the side wall of the heating element 111, the heating of the cutter head 112 becomes more uniform. The pressure plate 113 mechanically limits the extension of the cutter head, restricting the part of the cutter head that contacts the webbing, thus preventing excessive contact between the cutter head and the webbing and reducing the phenomenon of molten material sticking to the cutter.

[0040] On the one hand, the blade mounting groove 114 of the pressure plate 113 provides precise guidance for the blade 112, ensuring the straightness and stability of the cutting trajectory and avoiding rough cuts caused by blade offset in traditional free melting cutting; on the other hand, the pressure plate 113 can apply constant pressure in real time during the cutting process, which not only avoids molten layer residue (clumping) but also prevents webbing deformation caused by excessive pressure. The blade 112 cuts into the webbing with constant pressure under heating, so that a uniform molten sealing layer is formed on the cutting surface, which has both flatness and anti-fraying performance.

[0041] The modular cutter head assembly 102 adopts a split assembly structure (such as the first and second annular parts 106 being detachably connected, and the heating element 111 and the cutter head assembly 112 being installed independently). When a single cutter head is damaged or needs to be replaced, only the corresponding component needs to be disassembled without the need for overall machine shutdown for maintenance, which greatly reduces maintenance costs and time. At the same time, the equidistant layout design of the mounting rollers 101 supports simultaneous operation of multiple cutter heads or differentiated parameter settings, which can achieve efficient continuous slitting and meet the parallel requirements of different cutting widths and depths in complex webbing slitting processes, significantly improving equipment utilization and production efficiency.

[0042] This utility model adopts a double-ring component cooperative structure. The second ring component 106 achieves cutter head angle adjustment through rotation. Combined with the combined assembly structure of heating component 111 and cutter head component 112, the cutter head forms a precise positioning and cutting within the cutter head mounting groove 114 of the pressure plate 113, effectively reducing the sticking phenomenon. Through the adjustable pressure control system and precise cutter head extension, it avoids the sticking defect caused by excessive melting of the webbing cutting surface. The synergistic effect of mechanical pressure and thermal cutting ensures the flatness of the cut. At the same time, the modular structure design achieves the unity of efficient cutting of multi-specification webbing and convenient equipment maintenance, significantly improving the webbing processing quality and production adaptability.

[0043] In this embodiment of the present invention, a first collection cavity 116 and a second collection cavity 117 are respectively provided on the left and right side walls of the blade mounting groove 114. A scraper assembly 118 is respectively installed on the opposite side of the first collection cavity 116 and the second collection cavity 117. The scraper assembly 118 includes a cleaning scraper 119 rotatably mounted on the inner bottom surface of the collection cavity. A triangular limiting block 120 is fixed on the left and right side walls of the blade mounting groove 114. The cleaning scraper 119 abuts against the triangular limiting block 120 to make the cleaning scraper 119 tilted upward.

[0044] like Figure 6As shown, a first collection cavity 116 and a second collection cavity 117 are provided on the left and right side walls of the cutter head mounting groove 114, and a scraper assembly 118 with a cleaning scraper 119 is configured. The scraper is arranged at an angle by the abutting cooperation between the triangular limiting block 120 and the cleaning scraper 119. During the upward movement of the cutter head 112, the cleaning scraper 119 rotates to make room. During the downward movement of the cutter head 112, the limiting effect of the triangular limiting block 120 prevents molten debris adhering to the cutter head 112 from being cut. As the blade head 112 moves downward, the cleaning scraper 119 scrapes away debris in real time and guides it into the collection cavity, preventing debris from accumulating in the blade head mounting groove 114 and causing blockage or secondary adhesion. To improve the cleaning effect, the telescopic component 115 can drive the blade head 112 up and down multiple times. The dynamic cleaning effect of the angled scraper, combined with the rigid constraint of the triangular limiting block 120, ensures that the scraper and the side wall of the blade head 112 are in continuous contact to improve cleaning efficiency. The cavity debris collection design also enables the directional collection of debris, further ensuring the stability of the cut quality.

[0045] In this embodiment of the utility model, the end of the cleaning scraper 119 is provided with an oblique abutment surface 121, which is close to and parallel to the blade head 112.

[0046] like Figure 6 As shown, by designing the end of the cleaning scraper 119 as an oblique contact surface 121, it is parallel to and closely fitted with the side wall of the blade head 112. During the downward movement of the blade head 112, the oblique contact surface 121 moves close to the blade head surface with a constant contact pressure, accurately scraping away the molten residue attached to the side wall of the blade head. The parallel fit design not only enhances the dynamic fit stability between the scraper and the blade head 112, but also reduces the wear rate of the scraper and the blade head by uniformly dispersing the scraping stress. Ultimately, it achieves dual optimization of blade head self-cleaning and long-term durability, ensuring continuous and efficient slitting process and consistent cut quality.

[0047] In this embodiment of the utility model, the lower end face of the pressure plate 113 is provided with a pressure surface 122 that abuts against the product to be processed;

[0048] like Figure 5 As shown, by setting a pressure plane 122 on the lower end face of the pressure plate 113 that is in contact with the surface of the webbing to be processed, the pressure applied to the webbing is evenly distributed through planar contact during the cutting process. This not only prevents the webbing from wrinkling or shifting due to uneven pressure, thus affecting the cutting accuracy, but also suppresses the interference of cutting vibration on the flatness of the cut through full-fit support. The continuous and stable contact between the pressure plane 122 and the surface of the webbing also plays a limiting and guiding role, ensuring that the cutter head 112 cuts accurately along the preset path, while reducing the deformation and shift of the webbing cutting area caused by heat melting and shrinkage.

[0049] In this embodiment of the utility model, the telescopic component 115 includes a telescopic cylinder component 123 rotatably disposed on the upper end of the mounting side plate 104, a rotating connecting rod 124 is fixedly disposed on the cutter head mounting plate 109, and a converter component 125 is rotatably connected to the rotating connecting rod 124. The converter component 125 is fixedly connected to the working shaft of the telescopic cylinder component 123.

[0050] like Figure 3 As shown, the telescopic cylinder 123 is fixed to the upper end of the mounting side plate 104 in a rotating manner. Its working shaft is connected to the rotating connecting rod 124 of the cutter head mounting plate 109 via the adapter 125 to form a hinge transmission, so that the cylinder power output is converted into the adjustment of the cutter head mounting plate 109. This structure can dynamically adjust the cutting angle and depth of the cutter head 112 during the cutting process.

[0051] In this embodiment of the utility model, a pull rod 126 is fixedly provided on the adapter 125, and a pull rod mounting plate 127 is fixedly provided on the telescopic cylinder 123. A pull rod mounting hole 128 is provided on the pull rod mounting plate 127, and the pull rod 126 extends upward from the pull rod mounting hole 128.

[0052] The tie rod mounting plate 127 is provided with a buckle 129 that is snapped and fixed to the tie rod 126. One end of the buckle 129 is rotatably connected to the tie rod mounting plate 127, and the other end of the buckle 129 is provided with a buckle groove 130, which is snapped and engaged with the tie rod 126.

[0053] like Figure 2 and 3 As shown, by setting a modular quick-release structure consisting of a tie rod 126, a tie rod mounting plate 127, and a snap fastener 129, the tie rod 126 passes through the tie rod mounting hole 128 to achieve precise axial positioning. The snap fastener 129 forms an openable and closable snap-lock by cooperating with the snap fastener groove 130 through the rotation end, so that the connection between the adapter 125 and the telescopic cylinder 123 has both quick disassembly and rigid fixation characteristics. The one-way rotation unlocking design of the snap fastener 129 allows the operator to release or lock the tie rod 126 with one hand, which significantly reduces maintenance complexity and downtime. At the same time, the multi-point contact constraint between the snap fastener groove 130 and the tie rod 126 effectively disperses the load stress.

[0054] In this embodiment of the utility model, a mounting gap 131 is preset between the heating element 111 and the cutter head mounting plate 109, and a plurality of cutter head positioning holes 132 for mounting the cutter head 112 are fixed on the side wall of the heating element 111.

[0055] like Figure 4As shown in the embodiment of this utility model, by pre-setting an installation gap 131 between the heating element 111 and the cutter head mounting plate 109, redundant space is provided for the thermal expansion of the cutter head 112, avoiding stress concentration or structural deformation between the cutter head mounting plate 109 and the heating element 111 due to thermal deformation. At the same time, the heat insulation buffer formed by the gap can reduce the direct conduction of heat to the cutter head mounting plate 109, preventing overheating in non-cutting areas from affecting the life of the component. The multiple cutter head positioning holes 132 provided on the side wall of the heating element 111 support the modular and rapid assembly of cutter head components 112 of different specifications. The cutting angle, extension length and arrangement density of the cutter head can be flexibly adjusted through the differentiated layout of the holes, which can adapt to the needs of various types of webbing melting and cutting processes.

[0056] In this embodiment of the utility model, the upper end of the first annular member 105 is provided with an annular member fixing hole 133, and a bolt fixing member 134 that is fixedly connected to the annular mounting seat 103 is installed in the annular member fixing hole 133.

[0057] like Figure 7 As shown, by opening an annular fixing hole 133 at the upper end of the first annular part 105 and configuring a bolt fixing part 134, the first annular part 105 and the annular mounting seat 103 are rigidly connected by a bolt through-locking design. This not only strengthens the structural stability of the annular mounting groove 107 to resist high-frequency vibration and lateral load during the cutting process, but also achieves rapid positioning and repeated disassembly and assembly of the modular components through standardized thread fastening.

[0058] In one embodiment, the heating element 111 includes a polygonal heating block made of 304 stainless steel, on which a Watlow Firerod series cylindrical heater is mounted, with a built-in K-type thermocouple for precise temperature control, and a cutter head positioning hole 132 is provided on the side wall of the heating block.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. 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. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
