Description

Technical Field

[0001] The utility model relates to the technical field of rubber grinding equipment, in particular to a tool for grinding flash of rubber products. Background Art

[0002] The reasons for the formation of flash on molded rubber products include unreasonable mold structure, improper processing technology, low processing accuracy, unclean parting surface of mold deformation, excessive glue filling, etc. The formation of flash on the parting surface of rubber products not only causes material waste and increased process costs, but also affects product performance and causes environmental pollution. In the production and processing of rubber products, the treatment of flash is a very important process.

[0003] At present, most of the burrs are trimmed after freezing using a freezing trimmer, but the existing equipment lacks the ability to grind the edges of the rubber parts after the burrs are sheared. A Chinese patent with the authorization announcement number CN215036135U discloses a device for processing flash of rubber parts, including two upper and lower mounting seats rotatably mounted via a rotating shaft, a driving motor is provided between the mounting seats, and a telescopic member is coaxially provided at the output end of the driving motor, a height-adjustable grinding mechanism is arranged between the mounting seats via the telescopic member, and a shearing mechanism that can rotate with the rotating shaft is provided on the rotating shaft. The device can not only realize the cutting process of the flash of rubber parts on one device, but also grind the cut portion of the rubber parts after cutting, which greatly improves the efficiency of the device in processing the flash of rubber parts.

[0004] However, the above scheme still has certain shortcomings. After the rubber part is placed on the fixing frame and fixed, the shearing mechanism can only shear two side edges of the rubber part, while the shearing and grinding of the other two side edges of the rubber part requires the rubber part to be rotated and fixed again. The whole adjustment process is time-consuming and labor-intensive, and the shearing and grinding efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 2 , the utility model provides a technical solution:

[0026] like Figure 1-Figure 2 As shown, a tool for grinding flash of rubber products comprises a fixing component 1, a shearing component 2 and a grinding component 3, wherein the shearing component 2 is located above the fixing component 1, and the grinding component 3 is located at one side of the fixing component 1;

[0027] The fixing assembly 1 includes a rotating mechanism and a vacuum suction cup 104, wherein the vacuum suction cup 104 is located above the rotating mechanism, and the rubber member 4 is located above the vacuum suction cup 104 and is fixed by the vacuum suction cup 104;

[0028] The shearing assembly 2 includes a frame 206, a synchronous reverse adjustment mechanism and a cutter head 204, and the distance between the two cutter heads 204 is adjusted by the synchronous reverse adjustment mechanism;

[0029] The grinding assembly 3 includes a support platform 307, a first cylinder 304 and a belt 306 transmission mechanism. The support platform 307 is slidably connected to the base plate through the first cylinder 304. A grinding wheel cloth is provided on the outer side of the belt 306 of the belt 306 transmission mechanism. The belt 306 transmission mechanism is placed horizontally, and the height of the belt 306 transmission mechanism is adapted to the height of the vacuum suction cup 104.

[0030] Through the above technical solution, the center of the rubber part 4 is placed on the vacuum suction cup 104, the rubber part 4 is sucked and fixed by the vacuum suction cup 104, and then the positions of the two cutting heads 204 are adjusted according to the width of the rubber part 4, and the flash on both sides of the rubber part 4 are sheared through the shearing component 2.

[0031] After the shearing is completed, the shearing assembly 2 is reset, and the first cylinder 304 drives the support platform 307 and the belt 306 transmission mechanism on the support platform 307 to approach the rubber member 4, and then the belt 306 transmission mechanism is started. The rotation of the belt 306 transmission mechanism drives the grinding wheel cloth to rotate, thereby grinding the flash of the rubber member 4 after shearing.

[0032] When the grinding of one side of the rubber member 4 is completed, the first cylinder 304 drives the support platform 307 to return to its original position, and then the rotating mechanism drives the rubber member 4 to rotate 180° to grind the other side of the rubber member 4 .

[0033] Furthermore, the direction of the rubber member 4 can be adjusted by the rotating mechanism, and the cutter head 204 can be readjusted to adapt to the width of the other two sides of the rubber member 4 by the synchronous reverse adjustment mechanism, and then the other two sides of the rubber member 4 are sheared by the shearing assembly 2, and then the grinding process is repeated.

[0034] Through the above solution, the four side edges of the rubber member 4 can be sheared and polished, thereby improving the shearing and polishing effect of the flash edge, and at the same time improving work efficiency and saving manpower.

[0035] Furthermore, the rotating mechanism includes a turntable 101, a rotating shaft 102 and a gear shaft 103, one end of the rotating shaft 102 is connected to the turntable 101, the other end of the rotating shaft 102 is rotatably connected to the base plate, the gear shaft 103 is meshed with the turntable 101, and one end of the gear shaft 103 is connected to the driving motor.

[0036] Furthermore, the base of the vacuum suction cup 104 is fixed above the turntable 101, the rotating shaft 102 is a hollow structure, an opening is provided in the middle of the turntable 101, the air pipe of the vacuum suction cup 104 passes through the turntable 101 and the rotating shaft 102 to be connected to an external air source, and the air pipe of the vacuum suction cup 104 and the connector of the vacuum suction cup 104 are rotating joints.

[0037] Through the above technical solution, since the vacuum suction cup 104 is fixed on the turntable 101, when the turntable 101 rotates, the vacuum suction cup 104 and the rubber part 4 will be driven to rotate, so the air pipe connector of the vacuum suction cup 104 adopts a rotating joint to ensure that the vacuum suction cup 104 can absorb the rubber part 4 without being affected by the rotation.

[0038] Furthermore, the synchronous reverse adjustment mechanism includes a support rod 201, a double-headed reverse screw 202 and a slider 203, the positive thread end and the reverse thread end of the double-headed reverse screw 202 respectively pass through the two sliders 203, the middle part of the double-headed reverse screw 202 is rotatably connected to the support rod 201, the slider 203 is slidably connected to the support rod 201, and the cutter head 204 is fixed under the slider 203.

[0039] Through the above technical solution, by twisting the double-ended reverse threaded screw 202, the two sliders 203 can be driven to move closer or farther at the same time, and then the distance between the two cutter heads 204 can be synchronously adjusted. It can be known that the center lines of the rubber member 4, the vacuum suction cup 104, and the double-ended reverse threaded screw 202 are the same line, which facilitates the adjustment of the symmetrical cutter heads 204 to shear the flash of the rubber member 4.

[0040] Furthermore, the frame 206 is an L-shaped structure, the upper end of the frame 206 is located above the synchronous reverse adjustment mechanism, and a second cylinder 205 is provided between the support rod 201 and the frame 206 .

[0041] According to the above technical solution, the second cylinder 205 is used to control the support rod 201 to move up and down, thereby controlling the cutter head 204 to shear the flash of the rubber member 4. After the flash on both sides of the rubber member 4 are sheared, the second cylinder 205 is used to reset the rubber member 4, which is convenient for the grinding assembly 3 to grind the sheared rubber member 4 and also convenient for the rotation of the rotating mechanism without interfering with the cutter head 204.

[0042] Furthermore, the belt 306 transmission mechanism includes a belt 306, a driving wheel 301, a driven wheel 302, a tensioning mechanism 303 and a rotating motor, the rotating motor is located in the support platform 307, the driving wheel 301 and the driven wheel 302 are located on the side of the support platform 307 close to the fixed component 1, the driving wheel 301 and the driven wheel 302 extend out of the support platform 307, and the distance between the driving wheel 301 and the driven wheel 302 is greater than the length of the rubber member 4.

[0043] Through the above technical solution, the rotating motor in the support platform 307 drives the driving wheel 301 to rotate, and then drives the belt 306 to rotate through the cooperation of the driven wheel 302. A grinding cloth is attached to the outer side of the belt 306. The rotation of the belt 306 drives the rotation of the grinding cloth to grind the rubber member 4. The belt 306 and the grinding cloth near the side of the rubber member 4 extend out of the support platform 307, so that the grinding cloth can contact and rub against the rubber member 4. At the same time, the belt 306 can be tensioned by the tensioning mechanism 303 to prevent the belt 306 from slipping and falling.

[0044] Furthermore, the driving wheel 301 and the driven wheel 302 are I-shaped wheels, and the width of the grinding wheel cloth is greater than the thickness of the rubber member 4 .

[0045] The I-shaped wheel can limit the belt 306 from coming out, thereby ensuring the transmission of the belt 306. Meanwhile, the width of the belt 306 and the grinding wheel cloth is greater than the thickness of the rubber member 4, so the entire side of the rubber member 4 can be polished to improve the polishing effect.

[0046] Furthermore, a slide rail 305 is provided between the support platform 307 and the bottom plate, and the first cylinder 304 is located on a side of the support platform 307 away from the fixing assembly 1 .

[0047] Through the above technical solution, the first cylinder 304 drives the support platform 307 to slide along the slide rail 305 on the bottom plate, which makes it convenient for the grinding component 3 to grind the rubber part 4, and also facilitates the resetting of the grinding component 3, and facilitates the subsequent rotation of the rotating mechanism and the shearing of the shearing component 2.
