[0009] Specifically, the guide frame is provided with a blade groove perpendicular to the direction of travel of the liquid storage cotton, and the blade groove is adapted to the cutting blade so that the cutting blade can pass through the guide hole along the blade groove, thereby avoiding rigid collision between the cutting blade and the guide frame and reducing the wear rate of the equipment.

[0010] Specifically, the guide frame is provided with guide seats distributed at intervals, the guide holes are distributed on the guide seats, and the guide seats are detachably connected to the guide frame to facilitate the installation, removal and replacement of the guide seats.

[0011] Furthermore, the blade holder is provided with a U-shaped groove corresponding to the guide seat, and the cutting blade is detachably arranged in the corresponding U-shaped groove to facilitate the installation, removal and replacement of the cutting blade.

[0012] Specifically, a guide groove that is contracted along the traveling direction of the liquid storage cotton is provided upstream of the guide hole, thereby accurately guiding the liquid storage cotton into the guide hole.

[0013] Specifically, the liquid storage cotton cutting mechanism also includes:

[0014] a driving member, which is drivingly connected to the blade holder;

[0015] The guide piece is used to guide the movement of the blade holder.

[0016] In addition, the utility model also provides a liquid storage cotton discharging device, including a discharging part and a cutting part arranged in sequence along the material travel direction, wherein the discharging part is used to transport the formed liquid storage cotton to the cutting part, and then the liquid storage cotton is cut into a set length by the cutting part, and the cutting part adopts the above-mentioned liquid storage cotton cutting mechanism.

[0017] Specifically, the discharging portion includes a plurality of pairs of discharging rollers sequentially arranged along the direction of material travel, thereby realizing the traction and transportation of the formed liquid storage cotton.

[0026] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] Reference Figure 1 The utility model provides a liquid storage cotton cutting mechanism, comprising:

[0028] The guide frame 31 is provided with guide holes 33 distributed in a row for guiding the discharge of the liquid storage cotton;

[0029] The blade holder 35 is provided with a cutting blade 37 , which drives the cutting blade 37 to penetrate the guide hole 33 in a direction perpendicular to the moving direction of the liquid storage cotton to cut the liquid storage cotton in the guide hole 33 .

[0030] Among them, the guide hole 33 is preferably a circular hole, the aperture size of which is adapted to the formed liquid storage cotton, and the specific number and distribution position are adapted to the upstream hot melt channel; the cutting blade 37 can use a large blade, or a combination of multiple small blades, the number and distribution position of which can vertically penetrate the liquid storage cotton in each guide hole 33.

[0031] Specifically, the guide frame 31 is provided with a blade slot 34 perpendicular to the direction of travel of the liquid-reservoir cotton. The blade slot 34 is adapted to the cutting blade 37 so that the cutting blade 37 can pass through the guide hole 33 along the blade slot 34. On the one hand, this prevents the cutting blade 37 from rigidly colliding with the guide frame 31, greatly reducing the wear rate of the equipment. On the other hand, it ensures that the cutting blade 37 completely cuts through the liquid-reservoir cotton, effectively improving cutting efficiency and accuracy.

[0032] Preferably, the guide frame 31 is provided with guide seats 32 spaced apart from each other, the guide holes 33 are distributed on the guide seats 32, and the guide seats 32 are detachably connected to the guide frame 31. This modular design can reduce the difficulty of manufacturing the guide frame 31 and facilitate the assembly, disassembly and replacement of the guide seats 32, effectively reducing production and maintenance costs.

[0033] Furthermore, the blade holder 35 is provided with a U-shaped groove 36 corresponding to the guide seat 32. The shape and size of the U-shaped groove 36 are preferably adapted to the guide seat 32. Of course, it can also be larger than the size of the guide seat 32 to avoid the blade holder 35 from colliding with the guide seat 32 during the cutting process; the cutting blade 37 is detachably arranged in the corresponding U-shaped groove 36. On the one hand, it is convenient to realize the loading and unloading and replacement of the cutting blade 37, effectively reducing the maintenance cost; on the other hand, it can enhance the fixing strength of the cutting blade 37 and effectively improve the cutting stability.

[0034] For example, referring to Figure 1 、 Figure 2 The guide frame 31 is provided with 6 guide seats 32 distributed at equal intervals, each guide seat 32 is provided with a corresponding guide hole 33, and the guide seat 32 is provided with a blade groove 34 running through the middle of the guide hole 33; the blade holder 35 is provided with a U-shaped groove 36 corresponding to the guide seat 32, and a corresponding cutting blade 37 is fixed to the end of each U-shaped groove 36. In addition, based on the force direction of the liquid storage cotton, the guide hole 33 downstream of the blade groove 34 can adopt a half-hole design, and the end of the blade groove 34 adopts a chamfered design, which is conducive to the smooth entry of the cutting blade 37 into the blade groove 34. Of course, in other embodiments, the guide seat 32 can also be integrally provided on the guide frame 31, and a complete cutting blade 37 can also be directly fixed to the end of the U-shaped groove 36.

[0035] Preferably, refer to Figure 3 A guide groove 39 is provided upstream of the guide hole 33 , which is contracted along the direction of travel of the liquid storage cotton, thereby accurately guiding the liquid storage cotton into the guide hole 33 .

[0036] Furthermore, the liquid storage cotton cutting mechanism also includes:

[0037] a driving member 38 drivingly connected to the blade holder 35;

[0038] The guide member is used to guide the movement of the blade holder 35.

[0039] Specifically, the driving member 38 is fixedly connected to the guide frame 31, and its output end is drivingly connected to the blade frame 35, thereby driving the blade frame 35 to perform linear reciprocating motion relative to the guide frame 31; the guide member is arranged between the blade frame 35 and the guide frame 31, thereby achieving motion guidance of the blade frame 35. For example, referring to Figure 1The driving member 38 is a driving cylinder, the main body of which is fixedly connected to the guide frame 31 through a fixed frame. At the same time, a plurality of linear bearing assemblies are provided between the fixed frame and the blade frame 35 to guide the movement of the blade frame 35. In addition, the linear reciprocating drive of the blade frame 35 can also be achieved by other means to ensure the cutting accuracy of the cutting blade 37.

[0040] Reference Figure 3 The present invention also provides a liquid storage cotton discharging device, comprising a discharging portion 20 and a cutting portion 30 arranged in sequence along the material travel direction, wherein the discharging portion 20 is used to transport the formed liquid storage cotton to the cutting portion 30, and then the liquid storage cotton is cut into a set length by the cutting portion 30, and the cutting portion 30 adopts the above-mentioned liquid storage cotton cutting mechanism.

[0041] Specifically, the discharge section 20 includes multiple pairs of discharge rollers 21 arranged sequentially along the material's travel direction. This ensures that the liquid-reservoir cotton is accurately transported to the cutting section 30 while preventing it from bending or shifting during transport. Furthermore, the discharge section 20 includes an adjustment mechanism for adjusting the spacing between each pair of discharge rollers 21 to accommodate the production requirements of different types of liquid-reservoir cotton. The discharge rollers 21 are fitted with lawn strips, which are cost-effective and effectively increase friction and traction on the liquid-reservoir cotton.

[0042] For example, referring to Figure 3 The discharge section 20 and cutting section 30 are arranged vertically on the tooling support 10 to facilitate longitudinal material movement. The discharge section 20 comprises two pairs of horizontally arranged discharge rollers 21, one above the other. The lower pair of discharge rollers 21 are driven in opposite directions by servo motors 22 and are connected to the upper discharge rollers 21 via lawn belts, forming two sets of pulley conveyor mechanisms. Furthermore, the two pulley conveyor mechanisms are mounted on corresponding mounting brackets 23. The spacing between the two mounting brackets 23 is adjusted by two sets of left and right screw assemblies 24. Several linear bearing assemblies provide telescopic guidance between the two mounting brackets 23. To ensure synchronous locking of the two screw assemblies 24, a synchronous belt mechanism 25 provides synchronous transmission between the two screw assemblies 24. Of course, in other embodiments, the discharge section 20 and cutting section 30 can also be arranged horizontally to facilitate horizontal material movement.
