Technical Field

[0001] This application relates to the field of sponge processing equipment technology, and in particular to a sponge end cutting device. Background Technology

[0002] Due to its porous structure, softness, water absorption, and elasticity, sponge is in high demand in various fields such as cleaning and maintenance, product protection, liquid management, and sealing and sound insulation.

[0003] In related technologies: After sponge is foamed by foaming equipment in industrial production, its ends often have unevenness and insufficient foaming uniformity, which need to be trimmed by a cutting device. At present, the industry generally uses a combination of conveyor belt conveying and cutting tools to handle this.

[0004] Existing sponge end cutting devices have the following problems: sponge displacement during the cutting process leads to uneven cuts. In recent years, with the popularization of high-density sponge materials, higher requirements have been placed on the stability of cutting equipment. Summary of the Invention

[0005] To improve cutting stability, this application provides a sponge end cutting device.

[0006] The sponge end cutting device provided in this application adopts the following technical solution: A sponge end cutting device includes a support assembly, a conveying assembly, a cutting assembly, and a clamping assembly. The support assembly consists of a top beam and two columns. The cutting assembly is fixed to the top beam. The conveying assembly includes a plurality of parallel and symmetrically arranged conveying rollers mounted between the two columns and a conveyor belt laid on the conveying rollers. The clamping assembly includes two clamping panels arranged opposite each other with the center line of the conveying rollers as an axis. The two clamping panels can slide opposite each other along the length direction of the conveying rollers.

[0007] By adopting the above scheme, the rotation of the conveyor roller group drives the conveyor belt to rotate at a constant speed, transporting the sponge to the cutting station. The clamping assembly is activated, causing the two clamping panels to slide in opposite directions and apply balanced pressure from both sides of the sponge, thereby reducing sponge deviation. At the same time, it works with the cutting assembly to complete the end cutting and improve cutting stability.

[0008] Preferably, the clamping assembly further includes a first fixing frame and a cylinder, the cylinder being supported on the first fixing frame, and the telescopic rod of the cylinder being fixedly connected to the back of the clamping panel.

[0009] By adopting the above scheme, the cylinder directly drives the clamping panel to move in opposite directions through the telescopic rod, thereby improving the linearity and precision control of the clamping panel's movement.

[0010] Preferably, the clamping surface of the clamping assembly is provided with a multi-layer elastic composite material, including a surface silicone layer and a bottom airbag layer.

[0011] By adopting the above solution, scratches on the sponge surface are reduced, thus lowering the scrap rate.

[0012] Preferably, it further includes a control component, which includes a controller and an encoder disposed on the clamping panel, the encoder being electrically connected to the controller.

[0013] By adopting the above scheme, the encoder monitors the displacement of the clamping panel in real time and transmits the data to the controller to achieve closed-loop control.

[0014] Preferably, the control component further includes a width sensor disposed on the column, the width sensor being electrically connected to the controller.

[0015] By adopting the above scheme, a non-contact method is used to measure the width of the sponge, which, combined with the position data of the encoder, effectively improves the clamping accuracy and stability of the clamping panel.

[0016] Preferably, the cutting assembly includes a cutter, a second fixing frame, and a third fixing frame. The second fixing frame is fixed to the top beam, and the third fixing frame is coaxially fixed below the conveyor roller corresponding to the second fixing frame. The two ends of the cutter are respectively connected to the second fixing frame and the third fixing frame.

[0017] By adopting the above solution, the cutter is set perpendicular to the ground, and the direction of force is consistent with the direction of gravity, which reduces the deformation of the sponge caused by lateral vibration. The cutter blade completely penetrates the sponge during cutting, thus improving the cutting quality.

[0018] Preferably, the second and third fixing frames cooperate through a bottom motor and a chain and sprocket structure to enable the cutter to slide along the length direction of the top beam.

[0019] By adopting the above solution, transmission efficiency is improved and cutting continuity is ensured.

[0020] Preferably, the blade of the cutter is densely covered with fine serrations.

[0021] By adopting the above solution, the cutting contact area is reduced to increase pressure, effectively improving cutting efficiency and maintaining a smooth and flat cutting surface.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotating conveyor roller group drives the conveyor belt to rotate at a constant speed, transporting the sponge to the cutting station. The clamping assembly is activated, causing the two clamping panels to slide towards each other and apply balanced pressure from both sides of the sponge, thereby reducing sponge offset. At the same time, it works with the cutting assembly to complete the end cutting and improve cutting stability. 2. Improved the cutting efficiency and accuracy of the device; 3. Reduce mechanical damage to the sponge surface and lower the scrap rate. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a sponge end cutting device. (Refer to...) Figure 1-3 A sponge end cutting device includes a support assembly, a conveying assembly 2, a cutting assembly 4, and a clamping assembly 3. The support assembly consists of a top beam 12 and two columns 11, and the cutting assembly 4 is fixed on the top beam 12.

[0029] Furthermore, the conveying assembly 2 includes multiple parallel and symmetrically arranged conveying rollers 21 mounted between two columns 11 and a conveyor belt 22 laid on the conveying rollers 21. The clamping assembly 3 includes two clamping panels 33 arranged opposite each other with the center line of the conveying rollers 21 as the axis. The two clamping panels 33 can slide opposite each other along the length direction of the conveying rollers 21.

[0030] Correspondingly, the sponge blank is placed at the starting point of the conveyor belt 22. Multiple sets of conveyor rollers 21 rotate synchronously, driving the conveyor belt 22 to rotate at a uniform speed. After the sponge is transported to the cutting station, the clamping assembly 3 is activated. The two clamping panels 33 slide relative to each other until they abut against the two sides of the sponge and apply balanced pressure. At the same time, the cutting assembly 4 completes the end cutting of the sponge according to the preset path. Then the clamping panels 33 are reset, and the conveyor belt 22 sends out the sponge with the end trimmed. At the same time, new blanks enter, forming a continuous operation cycle.

[0031] In summary, the sponge is fixed without offset by applying pressure through the contact of the opposing surfaces of the two clamping panels 33, which reduces cutting errors and improves the cutting stability of the device.

[0032] Specifically, in this embodiment, the clamping assembly 3 further includes a first fixing frame 31 and a cylinder 32. The cylinder 32 is supported on the first fixing frame 31. The cylinder 32 is connected to an air supply device located below the conveyor roller 21 via an air pipe, and the telescopic rod of the cylinder 32 is fixedly connected to the back of the clamping panel 33.

[0033] Therefore, the cylinder 32 directly drives the clamping panel 33 to move horizontally through the telescopic rod and generates a constant clamping force. At the same time, it precisely controls the extension or retraction speed of the telescopic rod to reduce the slippage or deformation of the sponge during the cutting process. Compared with motor drive, there is no obvious heat generation problem, which reduces the risk of damage to the sponge structure.

[0034] Furthermore, the clamping surface of the clamping component 3 is fixed with a multi-layer elastic composite material, including a surface silicone layer and a bottom air bladder layer (not shown in the attached figure). The surface silicone layer is non-slip and wear-resistant, reducing mechanical contact and pinching damage to the sponge surface, thus reducing the scrap rate. At the same time, the bottom air bladder layer automatically conforms to the sponge thickness fluctuations through internal filling gas, dynamically compensating for the sponge's minor deformations and absorbing and attenuating the cutting amplitude during sponge cutting, reducing the load fluctuation of the cylinder 32 and extending its service life.

[0035] In summary, this structural design combines rigid clamping with flexible adaptation by fixing the surface silicone layer and equalizing the pressure of the bottom airbag layer, achieving adaptive and stable clamping, reducing the problem of single metal clamps easily crushing the sponge, and improving cutting quality.

[0036] On the other hand, in this embodiment, a control component 5 is also included. The control component 5 includes a controller (not shown in the figure), an encoder 51 fixed on the clamping panel 33, and a width sensor 52 fixed on the column 11. The encoder 51 and the width sensor 52 are both electrically connected to the controller.

[0037] Correspondingly, the width sensor 52 continuously monitors the width fluctuation of the sponge using a non-contact method, while the encoder 51 synchronously tracks the displacement of the clamping panel 33. Both convert physical parameters into electrical signals and transmit them to the controller.

[0038] Furthermore, the controller has a built-in PID algorithm that generates adjustment commands in real time by comparing electrical signal data with preset parameters. It automatically compensates for the pressure of cylinder 32 to maintain clamping stability, effectively reducing the risk of sponge deformation due to overpressure or slippage due to underpressure, and indirectly improving the yield rate. It is suitable for clamping cycles on automated production lines.

[0039] In addition, the cutting assembly 4 includes a cutter 41, a second fixing frame 43 and a third fixing frame 44. The second fixing frame 43 is fixed on the top beam 12, and the third fixing frame 44 is coaxially fixed below the conveyor roller 21 corresponding to the second fixing frame 43. The two ends of the cutter 41 are fixedly connected to the second fixing frame 43 and the third fixing frame 44 respectively, and the blade of the cutter 41 is densely covered with small serrations (not shown in the figure).

[0040] Therefore, the second fixed frame 43 and the third fixed frame 44 form a vertical axis reference, ensuring that the movement trajectory of the cutter 41 is orthogonal to the conveying direction, reducing the deformation of the sponge or the tilting of the cut caused by the lateral vibration of the cutter 41, and ensuring that the cutter cuts completely through the sponge, reducing the generation of irregular cuts such as wavy cuts. The impact force of the cutter 41 when it contacts the material can be absorbed by the two fixed frames, thus comprehensively improving the cutting accuracy and cutting quality.

[0041] Furthermore, in this embodiment, the fine serrations integrally formed on the blade increase pressure by reducing the cutting contact area, thereby achieving efficient cutting and reducing the occurrence of tearing or jamming of the cutter 41 in the sponge.

[0042] Specifically, in this embodiment, the second fixed frame 43 and the third fixed frame 44 are both equipped with the same chain sprocket structure 42, and the sprockets on the same side of the two chain sprocket structures 42 are rotatably connected to the bearing through a rotating shaft, and are driven by the bottom motor 45 to achieve synchronous transmission up and down, thereby driving the cutter 41 to move horizontally along the length direction of the top beam 12.

[0043] Furthermore, the chain and sprockets rarely experience elastic slippage or slippage during engagement, and the movement of the cutter 41 is strictly synchronized with the motor speed, effectively improving transmission efficiency. If the cutting resistance changes abruptly, the rigid engagement characteristics of the chain can reduce the risk of power interruption and maintain cutting continuity.

[0044] Meanwhile, a top motor 46 is fixed on the second fixed frame 43. The second fixed frame 43 has an eccentric wheel structure built in it. The circular surface of the eccentric wheel is fixedly connected to the output shaft of the top motor 46, and the curved surface of the eccentric wheel is hinged to the end of the cutter 41 that is away from the ground.

[0045] Therefore, when the output shaft of the motor rotates, it drives the eccentric wheel to rotate, and through the hinge structure, it drives the cutter 41 to move up and down within a small range, converting the rotational motion into the reciprocating motion of the vertical stroke of the cutter 41, ensuring a stable cutting trajectory, a smooth and flat cut without burrs or tears, which is especially suitable for elastic materials such as sponge, and improves the consistency of finished product dimensions.

[0046] Furthermore, the chain is made of high-strength alloy, which can withstand the impact load and high torque requirements in cutting operations. It has a longer maintenance cycle than traditional screw drive structures and is suitable for the horizontal long-distance movement of the cutter 41 in large cutting equipment.

[0047] The implementation principle of the sponge end cutting device in this application embodiment is as follows: After the sponge blank is accurately transported to the cutting station by the conveyor belt 22 driven synchronously by multiple conveyor rollers 21, the clamping panel 33 controlled by the cylinder 32 starts the opposing clamping program and applies balanced pressure to both sides of the sponge to achieve three-dimensional positioning and clamping, reducing the displacement of the material during the cutting process. The cutting component 4 then completes the end face trimming along the preset trajectory. The entire cycle enters the next cycle after the clamping component 3 is reset, realizing continuous and stable operation.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
