Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to an automatic cleaning rubber sheet cutting device. Background Technology

[0002] The adhesive sheet protects internal phone components, reduces impact damage, fills gaps between parts, improves assembly stability, and isolates dust and moisture, ensuring phone performance and lifespan. Cleaning the adhesive sheet after cutting and engraving is crucial. Residual debris adhering to the surface can affect the bonding precision between the adhesive sheet and phone components, leading to assembly gaps and reducing protective or auxiliary functions. Debris may also scratch the adhesive sheet surface, affecting appearance. In addition, a clean adhesive sheet prevents impurities from interfering with subsequent processes such as film application and bonding, ensuring phone assembly quality and reducing the risk of debris entering the phone and damaging components, thus ensuring phone performance and lifespan.

[0003] For example, in Chinese utility model publication CN214604614U entitled "A Silicone Sheet Cutting Device," a frame, a transverse motion mechanism, a longitudinal motion mechanism, and a cutting mechanism are included. A work platform is mounted on the upper end of the frame. The transverse motion mechanism includes a slide rail, a sliding frame, a first lead screw, and a motor. Slide rails are mounted on both sides of the frame. One end of the first lead screw is rotatably engaged with one end of the frame, and the other end passes through the frame and is connected to the motor shaft of the motor via a coupling. The two sides of the frame are slidably engaged with the sliding frame. A groove is provided at the lower end of the sliding frame, and the slide rail is placed within the groove. One sliding frame is fixedly connected to a lead screw nut, and the lead screw nut engages with the first lead screw. While this prior art can cut silicone sheets, it cannot clean them after cutting. Therefore, an automatically cleaning silicone sheet cutting device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed automatic cleaning rubber sheet cutting device to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An automatically cleaning rubber sheet cutting device includes a base, with a support plate one and a support plate two fixed to the top two sides of the base respectively. A cutting assembly is disposed between the base and the support plate two. A cleaning assembly is fixed to one side of the base. The cleaning assembly includes a cleaning tank fixed to one side of the base. A water pump is fixed to the outer wall of the cleaning tank. A conveying chamber connected to the output end of the water pump is fixed to the top of the cleaning tank. Several inverted conical fixing rings are disposed at the bottom of the conveying chamber inside the cleaning tank. A strainer is disposed inside the cleaning tank. A hollow rotating shaft is fixed to the top of the inverted conical fixing rings. A conveying pipe connected to the conveying chamber is fixed to the top of the hollow rotating shaft. A triangular fixing tube is rotatably connected to the bottom of the hollow rotating shaft. A nozzle is obliquely fixed to the bottom of each end of the triangular fixing tube.

[0007] As a further optimization of this utility model, the cutting assembly is provided with two pressing components, and the top of the base is provided with a conveyor belt that is below the cutting assembly and cooperates with the mesh.

[0008] As a further optimization of this utility model, the cutting assembly includes a servo motor three fixed to the outer wall of the support plate one, a guide box fixed between the base and the support plate two, a threaded rod fixed to the output end of the servo motor three rotating inside the guide box, a threaded fixing plate sliding on the inner wall of the guide box being threadedly sleeved on the outer wall of the threaded rod, an electric telescopic rod fixed to one side of the top of the threaded fixing plate, a motor base being fixed to the output end of the electric telescopic rod sliding through the threaded fixing plate, a cutting blade being fixed to the output end of the motor inside the motor base, and a debris collection groove cooperating with the cutting blade being opened on the top of the base.

[0009] As a further optimization of this utility model, the pressing assembly includes a sliding limiting rod that slides inside both sides of the threaded fixing plate. A fixing cover is fixed to the bottom of the sliding limiting rod. A spring is sleeved on the outer wall of the sliding limiting rod and fixed between the threaded fixing plate and the fixing cover.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, after the rubber sheet is cut, it is conveyed by a conveyor belt to the strainer in the cleaning assembly. The water pump is started to draw clean water and deliver it to the conveying chamber. Then, it is delivered to the nozzle through the conveying chamber. Under the action of the water flow, the nozzle rotates to clean, increasing the cleaning area. The water flow directly acts on the surface of the rubber sheet to wash away the debris remaining after cutting, thereby realizing automatic cleaning of the rubber sheet and maintaining the cleanliness of the rubber sheet surface.

The second servo motor drives the lower roller to rotate, and the rubber sheet is smoothly transported to the cutting area. First, the first servo motor drives the roller with blade to complete the longitudinal cutting. Then, the third servo motor drives the threaded rod to move. The height of the blade is adjusted with the electric telescopic rod. The motor drives the blade to rotate to achieve the transverse cutting. Finally, the rubber sheet is accurately cut, and the debris falls into the collection trough at the same time. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 6As shown, an automatically cleaning rubber sheet cutting device includes a base 1, which provides rigid support for the entire device to prevent displacement during cutting that could affect accuracy. The base 1 is characterized by having support plates 1-2 and 2-10 fixed to its top two sides, respectively, providing mounting support for rotating components. A cleaning assembly 9 is fixed to one side of the base 1. This cleaning assembly 9 is used for automatic cleaning of the cut rubber sheet, removing surface debris. The cleaning assembly 9 includes a cleaning box 902 fixed to one side of the base 1, providing a closed space for cleaning operations and preventing... To prevent wastewater splashing, a water pump 901 is fixed to the outer wall of the cleaning tank 902. An ISG50-160 pipeline centrifugal pump is selected, which provides the power for transporting the cleaning water. Its working principle is to generate pressure through impeller rotation to draw water out. A conveying chamber 903 is fixed to the top of the cleaning tank 902. The conveying chamber 903 is used to divert the cleaning water to each inverted conical fixing ring. The conveying chamber 903 is connected to the water pump 901, and this connection design ensures smooth water flow. Several inverted conical fixing rings 904 are set at the bottom of the conveying chamber 903. This design uses six inverted conical fixing rings; the specific number can be adjusted according to actual needs. Adjustments are made based on the actual situation. An inverted conical retaining ring 904 secures subsequent components. Located inside the cleaning tank 902, the inverted conical retaining ring 904 ensures that water flows directly onto the rubber sheet. A strainer 905 is installed inside the cleaning tank 902 to hold the rubber sheet and separate wastewater from debris for easy cleaning. A hollow rotating shaft 906 rotates at the top of the inverted conical retaining ring 904, facilitating the rotation of subsequent components. A conveying pipe 909 is fixedly connected to the top of the hollow rotating shaft 906, and this pipe connects to the conveying chamber 903 to provide water for subsequent operations. The hollow rotating shaft 906 has a fixed connection to a triangular fixing tube 907 at its bottom. The hollow rotating shaft 906 delivers water into the triangular fixing tube 907, facilitating the rotation of the triangular fixing tube 907. A nozzle 908 is fixed at an angle at the bottom of the triangular fixing tube 907. The nozzle 908 is fixed downward at the bottom of the triangular fixing tube 907. The reaction force of the water jet drives the nozzle 908, causing the nozzle 908 to drive the triangular fixing tube 907 to rotate horizontally, facilitating subsequent work. A conveyor belt 8 is provided on the top of the base 1. The conveyor belt 8 is used to transport the rubber sheet onto the strainer 905 for subsequent cleaning.

[0024] like Figure 1 , Figure 2 , Figure 4As shown, a cutting assembly 3 is provided between the base 1 and the support plate 2 10. The cutting assembly 3 is used to achieve transverse cutting of the rubber sheet. A guide box 302 is fixed between the base 1 and the support plate 2 10. The guide box 302 provides the mounting and guiding foundation for the threaded rod 303. The threaded rod 303 rotates inside the guide box 302. The threaded rod 303 drives the threaded fixing plate 304 to move through the threaded transmission. The threaded rod 303 is fixed to the output end of the servo motor 3 301 to ensure direct transmission of motor power. The threaded fixing plate 304 is sleeved on the outer wall of the threaded rod 303. The threaded fixing plate 304 converts the rotational motion into linear motion. The threaded fixing plate 304 slides on the inner wall of the guide box 302. The guide box 302 has a groove to limit the sliding trajectory of the threaded fixing plate 304 and ensure smooth movement. An electric telescopic rod 305 is fixed to the top of the threaded fixing plate 304. The electric telescopic rod is model DTZ300. The telescopic rod operates by extending and retracting a lead screw driven by a motor to achieve lifting and lowering. The output end of the electric telescopic rod 305 slides through the threaded fixing plate 304 to ensure stable extension and retraction of the telescopic rod. A motor base 306 is fixed to the output end of the electric telescopic rod 305. The motor base 306 is used to install the motor that drives the cutting blade. The output end of the motor inside the motor base 306 is fixed with the cutting blade 307. A three-phase asynchronous motor of model YS7124 is selected, which provides cutting power. The working principle is to drive the rotor to rotate through electromagnetic induction, which drives the cutting blade 307 to rotate at high speed to achieve cutting. A circular saw blade is selected as the tool, and the specific selection can be adjusted according to the actual situation. A debris collection groove 308 is opened on the top of the base 1. The debris collection groove 308 is used to collect the debris generated during cutting and keep the device clean. The debris collection groove 308 cooperates with the cutting blade 307 to ensure that the debris falls directly into the groove.

[0025] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the cutting assembly 3 is equipped with a pressing assembly 11. The pressing assembly 11 is used to fix the rubber sheet during cutting and prevent the rubber sheet from shifting. The pressing assembly 11 includes a sliding limiting rod 1101 that slides inside both sides of the threaded fixing plate 304. The sliding limiting rod 1101 restricts the movement direction of the fixing cover 1103. The fixing cover 1103 is fixed to the bottom of the sliding limiting rod 1101. The fixing cover 1103 fixes the rubber sheet by pressing. A spring 1102 is sleeved on the outer wall of the sliding limiting rod 1101. The spring 1102 provides elastic pressure to ensure that the fixing cover 1103 fits tightly against the rubber sheet without damaging the rubber sheet. The spring 1102 is fixed between the threaded fixing plate 304 and the fixing cover 1103 to achieve stable installation of the spring. A pulley 1104 rotates inside the fixing cover 1103. The pulley 1104 converts sliding friction into rolling friction, reducing the resistance when the rubber sheet is conveyed.

[0026] like Figure 1 , Figure 2 As shown, a servo motor 12, model SG-M200A, is fixed to the outer wall of support plate 12. Its function is to provide longitudinal cutting power. The working principle is to control the rotation angle through pulse signals to ensure cutting accuracy. A roller 4 is fixed to the output end of servo motor 12. Roller 4 drives the variable-pitch blades 5 to rotate synchronously. Roller 4 rotates between support plate 12 and support plate 20, ensuring stable rotation. Roller 4 is located on one side of the cutting assembly 3, achieving orderly connection between longitudinal and transverse cutting. Several variable-pitch blades 5 are sleeved on the outer wall of roller 14. This solution uses eight variable-pitch blades 5, which can be adjusted according to actual conditions. The variable-pitch blades 5 are used for longitudinal cutting of the rubber sheet. The spacing can be adjusted according to requirements. A servo motor 213 is fixed on one side of the base 1. The servo motor is model SG-M180A. Its function is to provide power for conveying the rubber sheet. The working principle is to receive signals to adjust the speed and achieve uniform feeding. A roller 37 is fixed at the output end of the servo motor 213. The roller 37 drives the rubber sheet to move through friction. The roller 37 is on one side of the roller 14 to ensure that the rubber sheet is conveyed to the longitudinal cutting station. The roller 37 rotates inside the base 1 to ensure that the roller is installed firmly. A roller 26 is set directly above the roller 37. The roller 26 and the roller 37 cooperate to clamp the rubber sheet to prevent slippage during conveying. The roller 26 rotates between the support plate 12 and the support plate 210 to ensure stable operation of the roller.

[0027] It should be noted that, in use, this self-cleaning rubber sheet cutting device first feeds the rubber sheet into the device between roller 6 and roller 7. Then, servo motor 13 is started, which drives roller 7 to rotate, thereby causing the rubber sheet to slide onto the pre-adjusted variable-pitch blade 5. Servo motor 12 drives roller 4, which in turn drives the variable-pitch blade 5 to perform longitudinal cutting of the rubber sheet. Then, servo motor 301 drives threaded rod 303, which in turn drives threaded fixing plate 304. Finally, electric telescopic rod 305 pushes the electric... The machine base 306 contains a motor that drives the cutting blade 307 to rotate, making horizontal cuts on the rubber sheet. When cleaning is required, the conveyor belt 8 carries the rubber sheet into the cleaning assembly 9 and onto the strainer 905. Then, the water pump 901 injects water into the conveying chamber 903 and then through the conveying pipe 909. The water is then conveyed by the conveying pipe 909 to the triangular fixing pipe 907, and then by the triangular fixing pipe 907 to the nozzle 908 that is tilted and fixed at the bottom of the triangular fixing pipe 907. The water flow drives the nozzle 908 to rotate, thereby cleaning a larger area of ​​the rubber sheet.

[0028] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
