Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting device technology, specifically to a sponge cutting device. Background Technology
[0002] Throughout human history, sponges have been widely used for various purposes. Currently, in order to reduce the cost of using sponges and promote their use, artificial sponges have been developed. The processing of artificial sponges generally involves material preparation, foaming, molding, cutting, packaging, and conveying. Among these, cutting is done to adapt the artificial sponge to the usage requirements, and to ensure cutting efficiency, it is usually completed by a cutting device.
[0003] Existing cutting devices can be broadly categorized into two types based on their cutting method: thermal cutting and blade cutting. When sponges are cut using thermal cutting tools such as hot wires, the high temperature of the tool causes thermal decomposition of the sponge material itself, producing smoke and odors. To ensure the health of workers, blade cutting devices are mostly used in sponge production workshops for this purpose.
[0004] However, during the cutting process of sponge, due to the special nature of its cutting method, the blade will generate a certain amount of sponge debris (chips). Over time, these chips will accumulate on the cutting device or machinery, affecting the normal use of the cutting device and even its service life. When cleaning the chips, it is necessary to stop the cutting of the sponge board, thus affecting the production efficiency of the sponge. Utility Model Content
[0005] This invention proposes a sponge cutting device that solves the problem of easy accumulation of cutting material on the cutting device in related technologies.
[0006] The technical solution of this utility model is as follows:
[0007] A sponge cutting device includes a device body, the device body including a cutting mechanism, the cutting mechanism including a cutting blade and a cutting tool spindle, the cutting blade being fixedly connected to the cutting tool spindle and linked with the cutting tool spindle, characterized in that the cutting mechanism further includes an air pump, the cutting blade having a cleaning air passage, the air outlet of the air pump communicating with the cleaning air passage, the cleaning air passage including a delivery chamber and a plurality of air jets; each of the air jets is opened on the circumferential surface of the cutting blade; the cutting blade includes a cutting tool body and a plurality of cutting blades, each of the cutting blades being evenly distributed circumferentially around the cutting tool body, each of the air jets being located between adjacent cutting blades; the cutting tool body includes a cutting section and a second air jet section, the second air jet section being located between the cutting section and the cutting tool spindle, each of the cutting blades being located on the cutting section, the second air jet section having a plurality of second air jets, the opening direction of each second air jet being parallel to the axial direction of the cutting blade.
[0008] Furthermore, each of the air jets is arranged sequentially along the axial direction of the cutting blade.
[0009] Furthermore, the projection surface of each of the jet nozzles in its opening direction is an arched structure.
[0010] Furthermore, each of the cutting blades is provided with an anti-clogging body at the end near the second air outlet. Each anti-clogging body is located below each second air outlet and is integrally formed with the cutting blade. The width of the end of the anti-clogging body near the second air outlet is smaller than the width of the end of the anti-clogging body away from the second air outlet.
[0011] The working principle and beneficial effects of this utility model are as follows:
[0012] The cutting mechanism in this invention differs from traditional cutting mechanisms. It incorporates an air pump, and the cutting blade, which performs the cutting action, has a cleaning air passage designed to cooperate with the air pump's nozzles. Specifically, the cleaning air passage includes a delivery pipe and several nozzles, each connected to the delivery pipe, which in turn connects to the air pump's outlet. This allows the airflow generated by the air pump to flow along the delivery pipe to each nozzle, ultimately exiting from each nozzle. As the cutting blade cuts the sponge, it also emits airflow from its surface. This airflow exerts an impact force on the shavings produced during cutting, thus washing them away and completing the shavings cleaning process. Attached Figure Description

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0022] like Figure 1 As shown, this embodiment proposes a sponge cutting device, which mainly includes a device body. The device body includes a cutting mechanism that performs the cutting function and a moving mechanism for moving the cutting mechanism to complete the cutting work. The moving mechanism is preferably a linear moving component such as a cable chain or a hydraulic lifting cylinder, so that the cutting mechanism can move in the three axes of "X", "Y" and "Z". That is, through the cooperation between the moving mechanism and the cutting mechanism, sponges of various shapes can be cut from the sponge board. The sponge shapes include, but are not limited to, cylindrical shapes.
[0023] like Figure 1 , Figure 5 As shown, the cutting mechanism in this embodiment mainly includes a cutting blade 1 and a cutting spindle 2. The cutting blade 1 is fixedly connected to the cutting spindle 2 and is linked with the cutting spindle 2. Preferably, the cutting blade 1 is fixed to the cutting spindle 2 by an external handle, thereby ensuring that the cutting blade 1 can perform cutting work under the rotational drive of the cutting spindle 2. The cutting mechanism also includes an air pump 3. The cutting blade 1 is provided with a cleaning air passage 11. The air outlet of the air pump 3 is connected to the cleaning air passage 11. Specifically, the cleaning air passage 11 includes a conveying pipe 111 and several air jets 112. The conveying pipe 111 is connected to the air outlet of the air pump 3, and each air jet 112 is connected to the conveying pipe 111. That is, the airflow generated by the operation of the air pump 3 flows along the conveying pipe 111 to each air jet 112 and is ejected from the air jet 112. Thus, during the cutting process, the surface of the cutting blade 1 in this embodiment will also eject airflow, which will impact the chips generated by cutting, thereby washing away the chips and completing the chip cleaning work.
[0024] Preferably, a rotary joint is provided between the air outlet of the air pump 3 and the cutting blade 1 to ensure that the gas delivery path between the air pump 3 and the cleaning air passage 11 is not affected by the rotation of the cutting blade 1, thereby ensuring the stability of gas delivery.
[0025] like Figures 2-4 As shown, in this embodiment, each air jet 112 is opened on the circumferential surface of the cutting blade 1. If the air jet 112 is located at the bottom of the cutting blade 1, there may be a situation where some sponge is squeezed into the interior of the cutting blade 1 along the air jet 112 during the cutting process (moving along the "Z" axis), which will interfere with the air output of the cutting blade 1 and thus affect the stability of the cleaning operation in this embodiment.
[0026] Meanwhile, the cutting blade 1 includes a blade body 12 and several cutting blades 13. Each cutting blade 13 is evenly distributed circumferentially around the blade body 12 to effectively disperse cutting force, reduce localized load, and thus improve machining stability and accuracy. Each air nozzle 112 is located between adjacent cutting blades 13, preventing contact between the air nozzles 112 and the sponge board being cut during the cutting process. This effectively reduces the possibility of the air nozzles 112 being blocked by the sponge, further improving the stability of the cleaning operation.
[0027] Each air nozzle 112 is arranged sequentially along the axial direction of the cutting blade 1, that is, each air nozzle 112 is distributed along the length direction of the cutting blade 13. Multiple air nozzles 112 can more effectively remove chips and impurities generated during the cutting process from the surface of the tool. By distributing air nozzles along the length direction of the cutting blade 1, uniform cleaning of the entire tool surface can be ensured, avoiding excessive chip residue in certain areas, thereby improving the overall cleaning efficiency.
[0028] The cutting blade 1 includes a cutting section 121 and a second air jet section 122. In this embodiment, the cutting blade 1 has more than one air jet section; the cleaning effect is improved through the cooperation of these various air jet sections. Specifically, the second air jet section 122 is located between the cutting section 121 and the blade spindle 2. Each cutting edge 13 is located on the cutting section 121. The second air jet section 122 is provided with several second air jet ports 1221. The opening direction of each second air jet port 1221 is parallel to the axial direction of the cutting blade 1. That is, the airflow direction from each second air jet port 1221 is perpendicular to the airflow direction from each air jet port 112. The two airflows cooperate to effectively clean the chips in the length and width directions of the cutting edge 13.
[0029] Each cutting blade 13 has an anti-clogging body 131 at one end near the second air outlet 1221. Each anti-clogging body 131 is located below each second air outlet 1221 and is integrally formed with the cutting blade 13 to ensure the connection strength between each cutting blade 13 and each anti-clogging body 131. The width of the end of the anti-clogging body 131 near the second air outlet 1221 is smaller than the width of the end of the anti-clogging body 131 away from the second air outlet 1221. That is, the anti-clogging body 131 is used to prevent the cutting blade 13 itself from blocking the second air outlet 1221 and disrupting the airflow path from the second air outlet 1221, so as to ensure that the airflow from the second air outlet 1221 can effectively act on the corresponding cutting blade 13, thus fully guaranteeing the cleaning effect of this embodiment.
[0030] Each jet nozzle 112 has an arched projection surface in its opening direction. Compared with the traditional circular opening, the arched opening can more effectively transfer pressure to the adjacent parts by taking advantage of its structural characteristics. This reduces the impact of the jet nozzle 112 on the overall structural strength of the cutting blade 1, making the overall structure of the cutting blade 1 more stable and ensuring the stability of the cutting operation.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
