Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin production equipment, specifically to a cotton core cutting roller for sanitary napkin processing. Background Technology

[0002] Cutting the sanitary napkin core is a crucial step in the manufacturing process. Currently, existing cutting equipment uses a fixed cutter structure, where the cutter and mold roller are integrally formed. Once the cutter wears out or is damaged, or if different sizes or shapes of sanitary napkin cores need to be cut, the entire cutter and mold roller must be disassembled and replaced. This not only increases production costs but also reduces production efficiency, failing to meet the high requirements of modern sanitary napkin manufacturing for equipment flexibility. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned technical problems and provide a cotton core cutting roller for sanitary napkin processing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a cotton core cutting roller for sanitary napkin processing, comprising a cutting roller body, cutting blades, and quick-release devices. The cutting roller body includes a roller body portion and a rotating shaft portion. The rotating shaft portion has two shafts, which are symmetrically arranged on both sides of the roller body portion. The roller body portion is provided with a cutting groove. The cutting blade has two blades, which are symmetrically arranged in the cutting groove. The quick-release devices are disposed between the cutting blade and the side wall of the cutting groove for quickly removing or installing the cutting blade. The quick-release devices are provided in eight sets, with two sets of quick-release devices arranged on each side of each cutting blade.

[0005] Furthermore, the cutting blade includes a blade holder and a blade, the blade being disposed on the blade holder and integrally formed with the blade holder.

[0006] Furthermore, the quick-release device includes a mounting cavity, a spring, a slot, and a locking post. The mounting cavity is disposed on the side wall of the blade holder, the spring is disposed within the mounting cavity, the slot is disposed on the side wall of the blade slot, and the locking post is disposed within the mounting cavity. One end of the locking post is connected to the spring, and the other end of the locking post extends out of the mounting cavity and is engaged in the slot.

[0007] Furthermore, the snap-fit ​​post has a cylindrical structure.

[0008] Furthermore, the end of the snap-fit ​​post is provided with a tapered structure.

[0009] Furthermore, the sidewall of the blade groove is provided with a guide groove for guiding the snap-fit ​​pin into the snap-fit ​​groove.

[0010] Furthermore, the tool holder is provided with a pin hole, which communicates with the mounting cavity, and the pin hole is provided with a limiting pin for preventing the locking post from disengaging from the mounting cavity.

[0011] Furthermore, a cold air channel for cooling the cutting blade is provided above the cutting roller body.

[0012] As can be seen from the above description of the present invention, compared with the prior art, the cotton core cutting roller for sanitary napkin processing provided by the present invention has the following advantages: by setting a quick-release device, the cutting blade can be quickly installed and removed. When the cutting blade is worn or needs to be changed in cutting size or shape, it is not necessary to disassemble the entire cutting roller body, but only to disassemble the cutting blade for replacement, which greatly improves production efficiency and reduces production costs.

[0017] The technical solutions of this 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 this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0018] Reference Figures 1-4As shown, a cotton core cutting roller for sanitary napkin processing includes a cutting roller body 1, cutting blades 2, and quick-release devices 3. The cutting roller body 1 includes a roller body portion 11 and a rotating shaft portion 12. Two rotating shaft portions 12 are symmetrically arranged on both sides of the roller body portion 11, used to install the cutting roller body 1 onto a sanitary napkin processing equipment and drive the cutting roller body 1 to rotate via a motor or other drive device to cut the sanitary napkin cotton core. The roller body portion 11 is provided with a blade groove 111. Two cutting blades 2 are symmetrically arranged within the blade groove 111. The quick-release devices 3 are disposed between the cutting blades 2 and the sidewalls of the blade groove 111 for quick removal or installation of the cutting blades 2. Eight sets of quick-release devices 3 are arranged on each side of each cutting blade 2 to ensure the stability and secure installation of the cutting blades 2.

[0019] The cutting blade 2 includes a blade holder 21 and a blade 22. The blade 22 is disposed on the blade holder 21 and is integrally formed with the blade holder 21.

[0020] The quick-release device 3 includes a mounting cavity 31, a spring 32, a slot 33, and a locking post 34. The mounting cavity 31 is disposed on the side wall of the blade holder 21, the spring 32 is disposed in the mounting cavity 31, the slot 33 is disposed on the side wall of the blade groove 111, and the locking post 34 is disposed in the mounting cavity 31. One end of the locking post 34 is connected to the spring 32, and the other end of the locking post 34 extends out of the mounting cavity 31 and is locked into the slot 33, thereby realizing the quick installation and fixation of the cutting blade 2 and the cutting roller body 1.

[0021] The locking post 34 has a cylindrical structure, and the end of the locking post 34 is provided with a tapered structure 341, which facilitates the end of the locking post 34 to be locked into the locking groove 33.

[0022] The side wall of the blade groove 111 is provided with a guide groove 1111 for guiding the snap-fit ​​post 34 into the snap-fit ​​groove 33, which further improves the ease of installation.

[0023] The tool holder 21 is provided with a pin hole 211, which communicates with the mounting cavity 31. The pin hole 211 is provided with a limiting pin 4 to prevent the snap-fit ​​post 34 from disengaging from the mounting cavity 31, thus ensuring the reliability of the quick-release device 3.

[0024] A cold air channel 5 is provided above the cutter roller body 1 for cooling the cutter 2. The cold air channel 5 is connected to an external air conditioner so that the cold air channel 5 is filled with cold air to cool the cutter 2, reduce the impact of heat generated by friction during the cutting process on the cutter 2, and extend the service life of the cutter 2.

[0025] Specifically, when installing the cutting blade 2, the locking pin 34 is pressed into the mounting cavity 31, so that one end of the locking pin 34 can enter the guide groove 1111. Then, the cutting blade 2 is pushed further until it is fully placed into the blade groove 111. At this time, the locking pin 34 automatically engages with the groove 33 under the elastic force of the spring 32, realizing the quick installation of the cutting blade 2. When the cutting blade 2 needs to be replaced, simply insert a screwdriver into the groove 33 and push the locking pin 34 out of the groove 33 to quickly remove the cutting blade 2.

[0026] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
