Description

Technical Field

[0001] This application relates to the field of rubber cutting technology, and in particular to a rubber block cutting device. Background Technology

[0002] Rubber is a highly elastic and tough solid. Rubber is usually cut using a rubber cutter, which is a rubber processing device that cuts natural or synthetic rubber blocks into smaller blocks that are easier to process.

[0003] A search revealed that CN213197688U discloses a novel rubber block cutting device. During operation, a third motor is activated, driving a first rotating roller to rotate via a reducer. The first rotating roller feeds the rubber block via a conveyor belt. The first motor then activates a gear, which, through meshing with a rack, moves a first sliding block. A second motor then activates a telescopic rod, moving a second sliding block up and down. The second sliding block moves an ultrasonic cutting blade up and down, which cuts the rubber block on the conveyor. This increases the cutting efficiency, reduces manual labor, and is equipped with casters for easy movement of the equipment.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need to be improved: the aforementioned equipment only achieves a single cutting effect. However, when cutting rubber blocks, due to the high elasticity of rubber, the blade may be "clamped" by the elastic material or result in an uneven cut when cutting directly, thereby increasing the cutting resistance and reducing the cutting accuracy. Utility Model Content

[0005] This application provides a rubber block cutting device to improve the following technical problems: the above-mentioned device only achieves a single cutting effect. However, when cutting rubber blocks, due to the high elasticity of rubber, the blade may be "clamped" by the elastic material or cause uneven cuts when cutting directly, thereby increasing cutting resistance and reducing cutting accuracy.

[0006] This application provides a rubber block cutting device, which adopts the following technical solution:

[0007] A rubber block cutting device includes a cutting table, a sliding support bracket, a cutting machine body, an X-axis moving stage, a positioning component, a pre-deformation component, and a rotary clamping component. The sliding support bracket is slidably connected to the outside of the cutting table. The cutting machine body is installed on the top outside of the sliding support bracket. The X-axis moving stage is slidably connected to the top of the cutting table. The positioning component is sleeved on the bottom inside of the sliding support bracket. The pre-deformation component is installed on both sides of the top of the sliding support bracket. The rotary clamping component is installed on one side of the X-axis moving stage.

[0008] The cutting table is used to place the rubber block. The sliding support bracket, in conjunction with the positioning component, is used to adjust the cutting position of the rubber block. The cutting machine body is used to cut the rubber block. The X-axis moving table is used to support the rotating clamping component and move close to the rubber block. The rotating clamping component is used to fix the rubber block and rotate and cut in conjunction with the cutting machine body. The pre-deformation component is used to release the internal stress of the rubber block and prevent the rubber cutting edge from clamping the cutting blade of the cutting machine body.

[0009] In one feasible technical solution of this application, the pre-deformation component includes an inclined bracket, a DC motor, a positioning shaft, a rotating disk, and a rubber abutment. The inclined bracket is fixedly connected to the top of the sliding support bracket, the DC motor is installed on one side of the inclined bracket, the positioning shaft is fixedly connected to the outside of the output end of the DC motor, the rotating disk is fixedly connected to the outside of the output end of the positioning shaft, and the rubber abutment is fixedly connected to the outside of the rotating disk and is used to abut against both sides of the rubber cutout.

[0010] In one feasible technical solution of this application, the rotary clamping assembly includes a geared motor, a connecting shaft, a locking gear, a guide shaft, and a pneumatic clamping arm. The connecting shaft is fixedly connected to the outside of the output end of the geared motor. The locking gear is respectively sleeved on the outside of the connecting shaft and the guide shaft, and the external teeth of the locking gear mesh with each other. The pneumatic clamping arm is installed on the outside of the guide shaft.

[0011] In one feasible technical solution of this application, the positioning component includes a stepper motor, a transmission gear and a transverse rack. The stepper motor is installed on the inner bottom of the sliding support bracket. The transmission gear is installed below the output end of the stepper motor and meshes with the outer teeth of the transverse rack.

[0012] In one feasible technical solution of this application, a power motor and a bidirectional screw are also provided on both sides of the cutting table. The power motor is installed on the outside of the cutting table, and the output end of the power motor is fixedly connected to one end of the bidirectional screw. The bidirectional screw is threaded on the inner bottom of the X-axis moving table.

[0013] In one feasible technical solution of this application, the top of the X-axis moving stage is further provided with an electric push rod and a Y-axis sliding frame. The output end of the electric push rod is fixedly connected to the surface of the Y-axis sliding frame, and the Y-axis sliding frame is slidably connected to the top of the X-axis moving stage and screwed to the surface of the reduction motor.

[0014] In one feasible technical solution of this application, the two sides of the cutting table are also fixedly connected with linear axes for limiting the movement path of the X-axis moving table.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This device uses a DC motor to drive a rotating disk to adjust the pressure of the abutment rod. Before cutting, the rubber abutment rod applies localized compression or stretching deformation to both sides of the cut, causing the rubber molecular chains to pre-orient themselves in the cutting area, reducing the clamping force on the blade due to elastic rebound. The continuous pressure of the abutment rod counteracts the elastic contraction of the rubber, preventing material rebound and wrapping around the blade during cutting, thereby reducing cutting resistance. The pre-deformed cut surface is smoother, with fewer burrs, improving cutting accuracy. Furthermore, the inclined support and guide shaft can dynamically adjust the angle and pressure of the abutment rod with the cutting depth, thus adapting to rubbers of different hardness.

[0036] The pre-deformation assembly 6 includes an inclined bracket 61, a DC motor 62, a positioning shaft 63, a rotating disk 64, and a rubber abutment 65. The inclined bracket 61 is fixedly connected to the top of the sliding support bracket 2. The DC motor 62 is installed on one side of the inclined bracket 61. The positioning shaft 63 is fixedly connected to the outside of the output end of the DC motor 62. The rotating disk 64 is fixedly connected to the outside of the output end of the positioning shaft 63. The rubber abutment 65 is fixedly connected to the outside of the rotating disk 64 and is used to abut against both sides of the rubber cutout.

[0037] The rotary clamping assembly 7 includes a geared motor 71, a connecting shaft 72, a locking gear 73, a guide shaft 74, and a pneumatic clamping arm 75. The connecting shaft 72 is fixedly connected to the outside of the output end of the geared motor 71. The locking gear 73 is respectively sleeved on the outside of the connecting shaft 72 and the guide shaft 74, and the external teeth of the locking gear 73 mesh with each other. The pneumatic clamping arm 75 is installed on the outside of the guide shaft 74.

[0038] The positioning component 5 includes a stepper motor 51, a transmission gear 52, and a transverse rack 53. The stepper motor 51 is installed on the bottom inner side of the sliding support bracket 2. The transmission gear 52 is installed below the output end of the stepper motor 51 and meshes with the outer teeth of the transverse rack 53. The transverse rack 53 is fixedly connected to one side surface of the cutting table 1.

[0039] The cutting table 1 is also equipped with a power motor 8 and a bidirectional screw 9 on both sides. The power motor 8 is installed on the outside of the cutting table 1, and the output end of the power motor 8 is fixedly connected to one end of the bidirectional screw 9. The bidirectional screw 9 is threaded on the bottom inner side of the X-axis moving table 4.

[0040] The top of the X-axis moving stage 4 is also provided with an electric push rod 10 and a Y-axis sliding frame 11. The output end of the electric push rod 10 is fixedly connected to the surface of the Y-axis sliding frame 11. The Y-axis sliding frame 11 is slidably connected to the top of the X-axis moving stage 4 and screwed to the surface of the reduction motor 71.

[0041] The cutting table 1 is also fixedly connected to both sides of a linear axis 12 for limiting the movement path of the X-axis moving table 4.

[0042] The general process of using the rubber block cutting device in this embodiment is as follows:

[0043] The rubber block is placed flat in the center of the cutting table 1. The linear shafts 12 on both sides ensure that the movement path of the X-axis moving stage 4 is not deviated. The power motor 8 is turned on, driving the bidirectional screw 9 to move the X-axis moving stage 4 along the linear shaft 12 and the groove direction of the built-in threaded groove 13 to the initial position. Then, the reduction motor 71 is started, which drives the connecting shaft 72 to drive the meshing locking gear 73 and the guide shaft 74 to rotate synchronously. The pneumatic clamping arm 75 clamps the two sides of the rubber block. The electric push rod 10 is adjusted to push the Y-axis sliding frame 11, and the clamping position is finely adjusted to adapt to workpieces of different thicknesses and to move closer to the cutting machine body 3. The stepper motor 51 drives the transmission gear 52 to move along the transverse rack 53, accurately positioning the sliding frame height bracket 2 to the target cutting line. The DC motor 62 is started, and the positioning shaft 63 drives the rotating disk 64 to adjust the angle, so that the rubber abutment 65 presses against the two sides of the cut, maintaining the pressure for 3 to 5 seconds, so that the rubber molecular chains are oriented and released local internal stress. Next, the cutting machine body 3 moves down along the sliding support bracket 2, and the blade contacts the pre-deformation area. Simultaneously, the reduction motor 71 is started, and through the engagement of the locking gear 73, it drives the rubber block to slowly rotate and cut in a straight or curved line. During this process, the rubber abutment 65 of the pre-deformation component 6 maintains pressure throughout the cutting process to prevent the cut from closing and clamping the blade.

[0044] The beneficial technical effects of the rubber block cutting device according to the embodiments of this application are roughly as follows:

[0045] This device uses a DC motor 62 to drive a rotating disk 64 to adjust the pressure of the abutment rod. Before cutting, the rubber abutment rod 65 applies local compression or stretching deformation to both sides of the cut, causing the rubber molecular chains to pre-orient in the cutting area, reducing the clamping force on the blade due to elastic rebound. The continuous pressure of the abutment rod counteracts the elastic contraction of the rubber, preventing material rebound and wrapping around the blade during cutting, thereby reducing cutting resistance. The pre-deformed cut surface is smoother, with fewer burrs, improving cutting accuracy. Furthermore, the inclined bracket 61 and the positioning shaft 63 can dynamically adjust the angle and pressure of the abutment rod with the cutting depth, thus adapting to rubbers of different hardness.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
