Description

Technical Field

[0001] This utility model relates to the field of sponge product processing technology, and in particular to a device for processing irregularly shaped sponges. Background Technology

[0002] In many areas of modern industrial production and daily life, irregularly shaped sponges play an indispensable role. From irregularly shaped sponge pads that provide cushioning protection for precision components in electronic products, to irregularly shaped sponge ornaments that fit unique spatial designs in home decoration, and to irregularly shaped sponge components such as seats and armrests in automotive interiors designed according to ergonomics, their presence is ubiquitous. Due to their unique shapes, irregularly shaped sponges can meet various special needs scenarios, which has made irregularly shaped sponge cutting technology a crucial link in modern industrial production. The optimization and upgrading of irregularly shaped sponge cutting methods and the intelligent development of control systems are of paramount importance for improving production efficiency, reducing production costs, and ensuring product quality.

[0003] Existing sponge cutting devices use a single cutting blade to cut the sponge layer by layer when cutting it into multiple blocks of the same thickness, which is inefficient.

[0004] An existing patent (publication number: CN221697014U) discloses a sponge processing device. Through the cooperation of a first servo motor, a first lead screw, a slide groove, and a first slider, multiple cutting blades can be driven to slide synchronously left and right to cut the sponge. The simultaneous cutting of the sponge by multiple cutting blades results in a fast cutting speed. Through the cooperation of a second servo motor, a second lead screw, a slide bar, a second slider, a third slider, and a hinge, the spacing between the multiple cutting blades can be adjusted synchronously to cut the sponge into different thicknesses, thus having a wide range of applications.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing irregularly shaped sponge processing devices typically lack the ability to flexibly adjust the tilt angle of the cutting blade, making it difficult to adapt to the cutting requirements of complex irregularly shaped sponges. This necessitates multiple replacements of the cutting blade or adjustments to the equipment angle, impacting processing efficiency. Furthermore, existing irregularly shaped sponge processing devices typically employ traditional mechanical clamps to compress and fix the sponge, which is not convenient for quickly fixing sponges of different thicknesses and shapes. Consequently, clamping time is long and frequent clamp adjustments are required, affecting production efficiency.

[0006] To address this, a device for processing irregularly shaped sponges is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a non-standard sponge processing device that solves the problems of existing non-standard sponge processing devices that typically lack flexible adjustment of the cutting blade tilt angle, making it difficult to adapt to the cutting needs of complex non-standard sponge contours. This necessitates multiple replacements of cutting blades or adjustments of equipment angles, affecting processing efficiency. Furthermore, existing non-standard sponge processing devices typically use traditional mechanical clamps to compress and fix the sponge, which is not convenient for quickly fixing sponges of different thicknesses and shapes, resulting in long clamping times and frequent clamp adjustments, thus affecting production efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a processing device for irregularly shaped sponges, including a processing table, a horizontal moving mechanism fixedly connected to the bottom of the processing table, a vertical moving mechanism provided at the top of the horizontal moving mechanism, a cutting component provided at the top of the vertical moving mechanism, and a fixing component provided at the front side of the processing table;

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application enables the electric heating knife to flexibly adjust its tilt angle by setting the cutting component, so as to adapt to the cutting needs of complex contours of irregularly shaped sponges, improve processing flexibility, and be more efficient than traditional fixed-angle cutting. Moreover, its electric heating knife has a built-in heating element, which can melt the sponge fibers instantly by rapidly heating up, avoiding the edge roughness or deformation caused by pulling in traditional mechanical cutting, improving the flatness and precision of the cutting surface, and ensuring product quality.

[0019] 2. This application can quickly fix the sponge to be processed by setting a fixing component, effectively reducing the vibration caused by the contact of the cutting tool during the cutting process and improving the smoothness of the cutting surface. Compared with the traditional mechanical clamping method of squeezing and fixing, this fixing component will not apply local pressure to the sponge surface, avoiding sponge deformation or internal structure damage caused by squeezing.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A special-shaped sponge processing device includes a processing table 1, a transverse moving mechanism 2 fixedly connected to the bottom of the processing table 1, a longitudinal moving mechanism 3 provided at the top of the transverse moving mechanism 2, a cutting component 4 provided at the top of the longitudinal moving mechanism 3, and a fixing component 5 provided at the front side of the processing table 1.

[0029] The cutting assembly 4 includes a fixed base 401 fixedly connected to the outside of the longitudinal moving mechanism 3. A lifting cylinder 402 is fixedly connected to the top of the fixed base 401. A connecting plate 403 is fixedly connected to the output end of the lifting cylinder 402. A guide rod 404 is fixedly connected to the top of the connecting plate 403. The guide rod 404 is slidably connected to the fixed base 401. A drive motor 405 is fixedly connected to the bottom plate of the connecting plate 403. A drive gear 406 is fixedly connected to the output end of the drive motor 405. A driven connecting rod 407 is meshed with the outside of the drive gear 406. The driven connecting rod 407 is rotatably connected to the connecting plate 403. An electric heating knife 408 is fixedly connected to the bottom of the driven connecting rod 407.

[0030] In this embodiment: the horizontal axis moving mechanism drives the fixed base 401 to move along the limiting slide rail 6, while the vertical moving mechanism 3 drives the cutting assembly 4 to move along the vertical axis, precisely positioning the electric heating knife 408 to the starting coordinate position of the sponge to be cut. Subsequently, the lifting cylinder 402 is activated, and its output end pushes the connecting plate 403 and the drive motor 405 below it, as well as the electric heating knife 408, to rise and fall as a whole. The guide rod 404 at the top of the connecting plate 403 slides along the guide hole on the fixed base 401, ensuring that the electric heating knife 408 rises and falls vertically to a height matching the surface of the sponge to be cut, thus completing the setting of the cutting depth. If an irregular contour is encountered that requires inclined cutting, the drive motor 405 is activated, driving the drive gear 406 to rotate. Through meshing with the outer rack of the driven connecting rod 407, the driven connecting rod 407 rotates around... The rotating connection with the connecting plate 403 swings, thereby causing the bottom electrothermal knife 408 to tilt to the left or right to the target angle to adapt to the cutting requirements of the irregular contour. After the angle adjustment is completed, the heating element built into the electrothermal knife 408 is energized and heated to the preset temperature. At this time, the horizontal moving mechanism 2 and the vertical moving mechanism 3 work together according to the preset cutting path program to drive the electrothermal knife 408 to move at a constant speed along the contour line of the irregular sponge. At the same time, the tilt angle and height of the electrothermal knife 408 are dynamically adjusted according to the contour changes to ensure cutting accuracy. After completing a section of irregular contour cutting, the drive motor 405 reverses to make the electrothermal knife 408 return to the vertical state so as to perform straight cutting or switch to the next section of contour cutting. After all cutting tasks are completed, the lifting cylinder 402 drives the electrothermal knife 408 to rise and reset.

[0031] Specifically, such as Figure 3 As shown, the fixing component 5 includes a support frame 501 fixedly connected to the top of the processing table 1. A vacuum adsorption plate 502 is fixedly connected inside the support frame 501, and a vacuum sensor 503 is provided on the outside of the support frame 501.

[0032] Specifically, such as Figure 3 As shown, a vacuum pump 504 is fixedly connected to the bottom of the processing table 1. A filter plate 505 is fixedly connected to the air inlet end of the vacuum pump 504. An air supply pipe 506 is connected to the output end of the vacuum pump 504. The air supply pipe 506 is connected to the vacuum adsorption plate 502.

[0033] Specifically, such as Figure 3 As shown, a control valve 507 is installed on the outside of the gas pipeline 506.

[0034] In this embodiment: During the processing of irregularly shaped sponges, the sponge to be processed is first placed on the vacuum adsorption plate 502 within the support frame 501, ensuring that the sponge completely covers the effective working area of ​​the adsorption plate. Then, the operator starts the vacuum pump 504. After the vacuum pump 504 starts working, air is drawn into the vacuum adsorption plate 502 through the air supply pipe 506, gradually creating a negative pressure environment on the surface of the adsorption plate. At this time, the vacuum sensor 503 monitors the pressure changes within the vacuum adsorption plate 502 in real time and feeds the data back to the control system. When the vacuum level reaches the preset adsorption pressure value, the control system confirms that the sponge has been firmly adsorbed. At this point, a signal is sent to close the control valve 507 to maintain the current vacuum state, completing the sponge fixing operation. Then, the sponge is cut... When the cutting component 4 processes the sponge, the vacuum pump 504 continuously operates, and the vacuum adsorption plate 502 maintains a stable negative pressure, effectively reducing the vibration caused by the contact of the cutting tool during the cutting process and ensuring the smoothness of the cut surface. If the part of the sponge to be processed changes, the operator can briefly open the control valve 507 through the control system to briefly increase the pressure in the vacuum adsorption plate 502. After the sponge position is adjusted, the control valve 507 is closed again to re-establish the negative pressure environment and achieve rapid repositioning of the sponge. When the cutting task is completed, the operator opens the control valve 507 to allow external air to enter the air supply pipe 506 and the vacuum adsorption plate 502, releasing the negative pressure state. At this time, the processed sponge product can be easily removed.

[0035] Specifically, such as Figure 5 As shown, the transverse movement mechanism 2 includes a servo motor 201 fixedly connected to the outside of the processing table 1. The output end of the servo motor 201 is fixedly connected to a horizontal axis lead screw 202. The outer side of the horizontal axis lead screw 202 is threadedly connected to a connecting seat 203. The outer side of the connecting seat 203 is fixedly connected to a support frame 204.

[0036] Specifically, such as Figure 4 As shown, the longitudinal moving mechanism 3 includes a motor body 301 fixedly connected to the top of the support frame 204. The output end of the motor body 301 is fixedly connected to a longitudinal axis lead screw 302. The outer side of the longitudinal axis lead screw 302 is threadedly connected to a movable seat 303, and the movable seat 303 is fixedly connected to the fixed seat 401.

[0037] In this embodiment: by setting up a servo motor 201, a horizontal axis lead screw 202, a connecting seat 203, and a support frame 204, the servo motor 201 drives the horizontal axis lead screw 202 to rotate. Through threaded transmission, the connecting seat 203 drives the support frame 204 to move laterally along the limit slide rails 6 on both sides of the processing table 1, thereby adjusting the horizontal axis coordinate of the electrothermal knife 408 on the horizontal plane. This ensures that the electrothermal knife 408 is accurately aligned with the starting point of the area to be cut in the sponge, while ensuring smooth and unbiased lateral movement. This meets the requirements for positioning accuracy and stability in processing complex contours of irregularly shaped sponges. The machine body 301, longitudinal lead screw 302, and moving seat 303 are connected by a motor. The motor body 301 drives the longitudinal lead screw 302 to rotate, and the moving seat 303 moves along the longitudinal axis through threaded transmission. This, in turn, drives the fixed seat 401 and the electrothermal knife 408, which are fixedly connected to the moving seat 303, to adjust the longitudinal axis coordinates. This allows for precise adjustment of the longitudinal axis coordinates of the electrothermal knife 408 on the horizontal plane. The system is linked with the transverse moving mechanism 2 to form a two-dimensional planar positioning system. This system can flexibly plan the cutting path according to different sponge processing requirements, significantly improving the adaptability and production efficiency of the device for processing diverse irregular sponges.

[0038] Specifically, such as Figure 4 As shown, both sides of the processing table 1 are fixedly connected to limit slide rails 6, and the outer side of the limit slide rails 6 is slidably connected to limit sliders 7, which are fixedly connected to the support frame 204.

[0039] Specifically, such as Figure 1 As shown, an anti-slip pad 8 is attached to the bottom of the processing table 1. The anti-slip pad 8 is made of rubber.

[0040] In this embodiment: by setting the limiting slide rail 6 and the limiting slider 7, when the support frame 204 moves, the limiting slider 7 at its bottom slides outside the limiting slide rail 6 on both sides of the processing table 1, thereby limiting the movement trajectory of the support frame 204 and providing guidance, effectively suppressing the lateral swaying and offset during the movement of the support frame 204, and ensuring the trajectory accuracy when the lateral moving mechanism 2 drives the cutting component 4 to move. By setting the anti-slip pad 8, the rubber anti-slip pad 8 can effectively prevent the processing table 1 from being displaced due to vibrations caused by motor operation, tool movement, etc. during the cutting process. At the same time, its elastic buffering performance absorbs the vibration energy of the equipment, reducing the transmission of vibration to the ground and the noise of equipment operation.

[0041] Working Principle: In the process of using the irregularly shaped sponge processing device, the sponge to be processed is first placed inside the support frame 501 in front of the processing table 1, covering the surface of the vacuum adsorption plate 502. Then, the vacuum pump 504 at the bottom of the processing table 1 is started, drawing air into the vacuum adsorption plate 502 through the air supply pipe 506, creating negative pressure in the surface adsorption pores. Under this negative pressure, the sponge is tightly adhered and fixed, preventing displacement during cutting. The vacuum sensor 503 on the outside of the support frame 501 monitors the pressure in real time. When the vacuum reaches a preset value, the system confirms firm adsorption and allows the cutting operation to begin. The filter plate 505 intercepts sponge fiber debris, preventing it from entering the vacuum pump 504 and causing blockage. The control valve 507 on the outside of the air pipe 506 is used to flexibly start and stop vacuum adsorption for easy workpiece replacement. Then, the servo motor 201 is started, which drives the horizontal axis lead screw 202 to rotate. Through threaded transmission, the connecting seat 203 and the support frame 204 above it move laterally along the limit slide rails 6 on both sides of the processing table 1, adjusting the horizontal axis coordinate of the hot knife 408 on the horizontal plane so that it is aligned with the starting position of the area to be cut on the sponge. Then, the motor body 301 is started, which drives the vertical axis lead screw 302 to rotate, causing the moving seat 303 to move along the vertical axis. The moving seat 303 is connected to the fixed seat 401 of the cutting assembly 4, thereby adjusting the vertical axis of the hot knife 408. When the heating knife 408 is positioned on the horizontal plane, the lifting cylinder 402 on the top of the fixed base 401 is activated, and the piston rod pushes the connecting plate 403 to move downwards in the vertical direction. At this time, the guide rod 404 on the top of the connecting plate 403 slides synchronously in the slide inside the fixed base 401 to ensure that the connecting plate 403 descends vertically and avoids angular deviation when the heating knife 408 contacts the sponge due to tilting. After the connecting plate 403 descends to the preset height, the heating knife 408 contacts the sponge surface. Its built-in heating element has been preheated and can instantly melt the sponge fibers to achieve tear-free cutting. Two drive motors 405 are installed at the bottom of the connecting plate 403, and their output ends are respectively connected to drive gears 40. 6. The drive gear 406 meshes with the driven connecting rod 407. When the drive motor 405 starts, the output shaft drives the drive gear 406 to rotate. The drive gear 406, through meshing transmission, causes the driven connecting rod 407 to reciprocate around its hinge point with the connecting plate 403, thereby driving the bottom electric heating knife 408 to swing synchronously, realizing the change of tilt angle. When only the left drive motor 405 starts, the electric heating knife 408 tilts to the left, and with the movement of the horizontal axis, a left oblique cut can be completed. When only the right drive motor 405 starts, the electric heating knife 408 tilts to the right, and with the movement of the horizontal axis, a right oblique cut can be completed. After the cutting is completed, the vacuum pump 504 and the control valve 507 are turned off, and then the processed sponge is taken out.

[0042] 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, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
