[0003] The existing roller chip conveyor device processes the rubber material on the outer wall of the roller by always keeping a scraper against the outer wall of the roller, and then driving the roller to fit the end of the scraper and rotate continuously to perform the cleaning operation. However, over time, the outer wall of the roller will be rubbed, causing wear and damage to the roller, thus affecting the service life of the roller. In view of this, a double-layer scraper roller chip conveyor device which has been used for machine tools is proposed. Summary of the invention

An auxiliary device for improving the cleaning effect is arranged on the top of the connecting frame, a transmission device is arranged on the side of the No. 1 scraper away from the driving device, and a striking device for knocking the outer wall of the roller is arranged on the bottom of the connecting frame; wherein the auxiliary device comprises a cylinder, an L-shaped connecting block, a No. 2 scraper, a sponge pad, a ramp block, a moving block, a transmission spring, a bending rod, a box body, a fixed plate and a baffle plate; the cylinder is fixed to the side wall of the connecting frame, the L-shaped connecting block is slidably mounted on the top of the connecting plate, the side wall of the L-shaped connecting block is fixedly connected to the output end of the cylinder, the side of the L-shaped connecting block away from the cylinder is slidably connected to the side wall of the No. 2 scraper, and a sponge pad is fixed on the side of the No. 2 scraper away from the L-shaped connecting block. When the cylinder is started, the L-shaped connecting block can be driven to approach the roller, so that the sponge pad and the outer wall of the roller are closely fitted.

[0007] According to the above technical solution, one side of the transmission spring is fixed to the top of the moving block, and the other side of the transmission spring is fixed to the inner wall of the fixed plate. When the moving block moves upward, the transmission spring will be compressed.

[0008] According to the above technical scheme, the transmission device includes a connecting seat, a rotating shaft, a roller, an extrusion rod, a triangular block, a connecting spring, a cam, a baffle, a reset spring, a movable seat, an inclined groove, a sliding rod and a blocking plate; the connecting seat is fixed to the side wall of the L-shaped connecting block, the rotating shaft passes through the connecting seat and is rotatably connected at the penetration point, the roller is fixed to the outer wall of the rotating shaft, the triangular block is fixed to the side wall of the second scraper, the extrusion rod is fixed to the side wall of the roller, and the cam is fixed to the end point of the rotating shaft. When the L-shaped connecting block moves, it can drive the connecting seat to move, and can drive the roller to fit with the outer wall of the roller, and then when the roller rotates, the roller can be driven to rotate by friction. When the roller rotates, it can drive the extrusion rod to rotate, so that the extrusion rod will contact the arc surface of the triangular block, so that the extrusion rod can squeeze the triangular block and the second scraper to move, so that the connecting spring is deformed, and when the extrusion rod rotates to no longer contact the triangular block, the second scraper can be reset by the connecting spring.

When the rotating shaft rotates, the cam can be driven to rotate. When the end with a small radius of the cam rotates to the bottom of the rotating shaft, the cam will squeeze the baffle to move downward, causing the return spring to stretch. When the end with a large radius of the cam rotates to the bottom of the rotating shaft, the cam will not contact the baffle, and the return spring can drive the baffle to move upward for reset.

[0010] According to the above technical solution, the outer wall of the movable seat is slidably connected to the inner wall of the connecting frame, the inclined groove is opened on the movable seat, and the inner wall of the inclined groove is in contact with the outer wall of the sliding rod. When the baffle moves downward, the sliding rod can move in the inclined groove, so that the sliding rod squeezes the inclined groove and drives the movable seat to move in the connecting frame.

[0011] According to the above technical solution, one side of the connecting spring is fixed to the inner wall of the No. 2 scraper, and the other side of the connecting spring is fixed to the side wall of the L-shaped connecting block.

[0013] According to the above technical solution, one end of the articulated rod is hinged on the L-shaped transmission plate, the other end of the articulated rod is hinged on the side wall of the slider, and the knocking ball is fixed on the side of the slider away from the articulated rod. When the baffle moves downward, the baffle drives the L-shaped transmission plate to move downward, causing the L-shaped transmission plate to squeeze the articulated rod, causing the articulated rod to rotate at the hinge, thereby allowing the articulated rod to push the slider to move, allowing the knocking ball to knock on the outer wall of the roller.

[0014] The present invention provides a double-layer scraper roller chip conveyor device for a machine tool. It has the following beneficial effects:

[0015] (1) The present invention sets an auxiliary device to maintain a certain gap between the first scraper and the outer wall of the roller, so that the thicker rubber attached to the outer wall of the roller can be scraped off first. After the thicker rubber is cleaned, the cylinder is started to make the sponge pad of the second scraper fit tightly with the outer wall of the roller, so that the roller can rotate in accordance with the sponge pad, thereby cleaning off the thinner layer of rubber left on the outer wall of the roller; and through the cooperation of the inclined block, the moving block and the bending rod, the shielding plate moves upward without blocking the liquid outlet pipe of the box body, so that the cleaning liquid in the box body is discharged from the liquid outlet pipe and drips on the outer wall of the roller, so that the cleaning liquid cooperates with the sponge pad to achieve a better cleaning effect.

[0016] (2) The present invention sets a transmission device. When the L-shaped connecting block moves toward the roller, it can drive the roller to contact the outer wall of the roller, so that the friction force enables the roller to drive the roller to rotate. Through the cooperation of the extrusion rod, the triangular block and the connecting spring, when the roller is in contact with the sponge pad and rotates, the sponge pad also moves back and forth, so that the sponge pad can better clean the outer wall of the roller; when the roller drives the rotating shaft to rotate, the cam can be rotated to squeeze the baffle back and forth to move. Through the cooperation of the reset spring, the sliding rod, the moving seat, the inclined groove and the blocking plate, when the No. 2 scraper drives the sponge pad to move back and forth, the No. 1 scraper moves back and forth in the connecting plate. When the No. 1 scraper moves into the connecting plate, the blocking plate can block the rubber scraped off the surface of the No. 1 scraper, so that the rubber falls from the No. 1 scraper, which is convenient for the next cleaning operation.

[0017] (3) The present invention provides a striking device. When the baffle moves downward, the L-shaped transmission plate moves downward, so that the L-shaped transmission plate squeezes the hinge rod, causing the hinge rod to rotate at the hinge, so that the hinge rod can push the slider to move toward the roller, thereby driving the striking ball to strike the outer wall of the roller, knocking the rubber material remaining on the outer wall of the roller off, thereby further improving the effect of cleaning the roller.

The baffle plate 810 is fixed to the end of the bending rod 89 away from the moving block 87, and the side wall of the baffle plate 810 is in contact with the inner wall of the box body 86. One side of the transmission spring 88 is fixed to the top of the moving block 87, and the other side of the transmission spring 88 is fixed to the inner wall of the fixed plate 85.

[0028] By maintaining a certain gap between scraper No. 11 and roller 3, scraper No. 11 does not fit tightly against the outer wall of roller 3 when roller 3 rotates, thereby preventing roller 3 from always fitting against the outer wall of scraper No. 11, causing large-area wear on the outer wall of roller 3, causing damage to roller 3 and affecting service life. Scraper No. 11 scrapes off the thicker rubber material attached to the outer wall of roller 3 first, leaving a relatively thin rubber material on the outer wall of roller 3.

[0029] By setting a No. 2 scraper 82 and a sponge pad 83 at the cleaning position of the No. 2 scraper 82, when the No. 1 scraper 11 finishes cleaning, the sponge pad 83 is fitted with the outer wall of the roller 3 through the cylinder 81, so that the roller 3 is fitted with the outer wall of the sponge pad 83 and rotates to clean the relatively thin rubber on the outer wall of the roller 3. Due to the flexibility and deformability of the sponge pad 83, the sponge pad 83 will not cause greater wear to the outer wall of the roller 3, and it is convenient to clean the thinner rubber.

[0030] When the L-shaped connecting block 811 moves, it can squeeze the moving block 87 and the bending rod 89 to move upward, so that the shielding plate 810 moves upward without blocking the liquid outlet pipe of the box 86, and the cleaning liquid is added to the box 86, so that the cleaning liquid in the box 86 is discharged from the liquid outlet pipe and drips on the outer wall of the roller 3, so that the cleaning liquid cooperates with the sponge pad 83, so that the cleaning effect is better.

[0031] When the present embodiment is working, when the roller 3 needs to be cleaned, the motor is started to make the small gear rotate forward, so that the small gear can drive the large gear 5 to rotate reversely, so that the large gear 5 drives the roller 3 to rotate in contact with the outer wall of the first scraper 11. The first scraper 11 can scrape off a certain thickness of the rubber on the outer wall of the roller 3, so that a small amount of relatively thin rubber is attached to the outer wall of the roller 3. When the rubber on the outer wall of the roller 3 needs to be cleaned, the cylinder 81 is started, The cylinder 81 drives the L-shaped connecting block 811 to approach the roller 3, so that the sponge pad 83 on the second scraper 82 can be pressed against the outer wall of the roller 3. When the L-shaped connecting block 811 approaches the roller 3, the inclined surface of the inclined surface block 84 will squeeze the bottom of the moving block 87, so that the moving block 87 will move upward under the squeezing force, and the transmission spring 88 will be compressed. When the moving block 87 moves upward, it can drive the bending rod 89 to move upward. When the bending rod 89 moves upward, The shielding plate 810 is moved upward in the box 86 to shield the liquid outlet pipe of the box 86, so that the cleaning liquid in the box 86 flows into the outer wall of the roller 3 through the liquid outlet pipe, and the roller 3 rotates in contact with the sponge pad 83, so that the sponge pad 83 can clean a small amount of thin rubber attached to the outer wall of the roller 3. When the sponge pad 83 is not needed to clean the outer wall of the roller 3, the cylinder 81 can be started to drive the L-shaped connecting block 81 to move the cleaning liquid to the outer wall of the roller 3. 11 moves away from the roller 3, so that the L-shaped connecting block 811 drives the second scraper 82 and the sponge pad 83 to move away. When the L-shaped connecting block 811 is reset, the L-shaped connecting block 811 will not squeeze the moving block 87. Since the transmission spring 88 is in a compressed state, the transmission spring 88 can push the moving block 87 to move downward, so that the moving block 87 drives the bending rod 89 to move downward, and the shielding plate 810 can shield the liquid outlet pipe of the box body 86, so that the cleaning liquid discharge operation is no longer performed.

[0032] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a transmission device is provided on the side of the first scraper 11 away from the driving device 4, a striking device for striking the outer wall of the roller 3 is provided at the bottom of the connecting frame 6, and the transmission device includes a connecting seat 91, a rotating shaft 92, a roller 93, an extrusion rod 94, a triangular block 95, a connecting spring 96, a cam 97, a baffle 98, a reset spring 99, a moving seat 910, a chute 911, a slide bar 912 and a blocking plate 913; the connecting seat 91 is fixed to the side wall of the L-shaped connecting block 811, the rotating shaft 92 passes through the connecting seat 91, and the penetration is rotatably connected, the roller 93 is fixed to the outer wall of the rotating shaft 92, and the triangular block 95 is fixed to the side wall of the second scraper 82, The extrusion rod 94 is fixed to the side wall of the roller 93, the cam 97 is fixed to the end point of the rotating shaft 92, the baffle 98 is slidably installed on the inner side of the connecting frame 6, one side of the reset spring 99 is fixed to the inner side of the connecting frame 6, and the other side of the reset spring 99 is fixed to the top of the baffle 98, the slide bar 912 is fixed to the side wall of the baffle 98, the outer wall of the movable seat 910 is slidably connected to the inner wall of the connecting frame 6, the inclined groove 911 is opened on the movable seat 910, and the inner wall of the inclined groove 911 is fitted with the outer wall of the slide bar 912, one side of the connecting spring 96 is fixed to the inner wall of the No. 2 scraper 82, and the other side of the connecting spring 96 is fixed to the side wall of the L-shaped connecting block 811, and the side wall of the No. 1 scraper 11 is fixedly connected to the side wall of the movable seat 910.

[0033] When the L-shaped connecting block 811 moves toward the roller 3, it can drive the roller 93 to contact the outer wall of the roller 3. The roller 3 rotates and the roller 93 is driven to rotate due to the friction force. Through the cooperation of the extrusion rod 94, the triangular block 95 and the connecting spring 96, when the roller 3 is attached to the sponge pad 83 and rotates, the sponge pad 83 also moves back and forth left and right, increasing the friction force with the outer wall of the roller 3, so that the sponge pad 83 has a better effect of cleaning the outer wall of the roller 3.

[0034] When the roller 93 drives the rotating shaft 92 to rotate, the cam 97 can be rotated to squeeze the baffle 98 back and forth to move. Through the cooperation of the reset spring 99, the slide rod 912, the moving seat 910, the inclined groove 911 and the blocking plate 913, when the No. 2 scraper 82 drives the sponge pad 83 to move back and forth, the No. 1 scraper 11 moves back and forth in the connecting plate 7. When the No. 1 scraper 11 moves toward the connecting plate 7, the blocking plate 913 can block the rubber scraped off the surface of the No. 1 scraper 11, so that the rubber falls from the No. 1 scraper 11, which is convenient for the next cleaning operation. The distance from the center of the rotating shaft 92 to the end of the cam 97 away from the rotating shaft 92 is shorter than the distance from the center of the roller 93 to the outer wall. Therefore, when the roller 93 contacts the roller 3, the cam 97 rotates without contacting the roller 3.

[0035] The striking device includes an L-shaped transmission plate 101, a hinged rod 103, a knocking ball 105, a slider 104 and a support platform 102; the L-shaped transmission plate 101 is fixed to the side wall of the baffle 98, the support platform 102 is fixed to the bottom of the connecting frame 6, the slider 104 is slidably installed on the inner side of the support platform 102, one end of the hinged rod 103 is hinged on the L-shaped transmission plate 101, the other end of the hinged rod 103 is hinged on the side wall of the slider 104, and the knocking ball 105 is fixed to the side of the slider 104 away from the hinged rod 103.

[0036] There are multiple groups of sliders 104 and knocking balls 105, and the multiple groups of sliders 104 and knocking balls 105 are arranged in a linear array on the support platform 102. The knocking balls 105 knock the outer wall of the roller 3 back and forth, so that the rubber and the like remaining on the outer wall of the roller 3 can be knocked off, further improving the cleaning effect of the roller 3.

[0037] When the present embodiment is working, when the L-shaped connecting block 811 approaches the roller 3, the L-shaped connecting block 811 can drive the connecting seat 91 to move. When the connecting seat 91 moves, the rotating shaft 92 can drive the roller 93 to approach the roller 3, so that the outer wall of the roller 93 contacts the outer wall of the roller 3. When the roller 3 reverses, the roller 3 can rub the roller 93 to rotate, driving the squeezing rod 94 fixed on the surface of the roller 93 to rotate. When the squeezing rod 94 rotates to contact the inclined surface of the triangular block 95, the inclined surface of the triangular block 95 is affected. The squeezing force causes the triangular block 95 to move away from the roller 93, and causes the triangular block 95 to drive the second scraper 82 to move, causing the connecting spring 96 to deform. When the squeezing rod 94 rotates to no longer contact the triangular block 95, the connecting spring 96 is in a deformed state, so that the connecting spring 96 can drive the second scraper 82 to reset. Therefore, when the roller 93 drives the squeezing rod 94 to rotate, the triangular block 95 can drive the second scraper 82 to move back and forth, so that the sponge pad 83 fits the outer wall of the roller 3 and moves back and forth, increasing the contact between the sponge pad 83 and the roller 3. The friction between the rollers 3 enables the sponge pad 83 to better remove the thinner rubber material attached to the outer wall of the roller 3, and when the roller 93 rotates, it can drive the shaft 92 and the cam 97 to rotate. When the end of the cam 97 with a smaller radius rotates to the bottom of the shaft 92, the shaft 92 will squeeze the baffle 98, so that the baffle 98 moves downward, and the return spring 99 is stretched. When the end of the cam 97 with a larger radius rotates to the bottom of the shaft 92, the cam 97 does not squeeze the baffle 98, and the return spring 99 is in a compressed state, so that The baffle plate 98 is driven to move upward to reset. When the baffle plate 98 moves downward, the slide bar 912 can move downward, so that the slide bar 912 can move in the inclined groove 911 provided on the moving seat 910. The slide bar 912 squeezes the inclined groove 911, so that the inclined groove 911 is squeezed to drive the moving seat 910 away from the roller 3, so that the moving seat 910 drives the first scraper 11 to move toward the connecting plate 7. The impurities such as rubber on the first scraper 11 can be blocked by the blocking plate 913, so that the rubber and impurities attached to the first scraper 11 can be discharged;

[0038] When the baffle 98 moves downward, it can drive the L-shaped transmission plate 101 to move downward, so that the L-shaped transmission plate 101 can squeeze the hinged rod 103, so that the hinged rod 103 rotates at the hinge, so that the hinged rod 103 can squeeze the slider 104 to get close to the roller 3, and the slider 104 can drive the knocking ball 105 to move toward the roller 3, so that the knocking ball 105 can knock on the outer wall of the roller 3. When the baffle 98 drives the L-shaped transmission plate 101 to move upward, the L-shaped transmission plate 101 can pull the hinged rod 103, so that the hinged rod 103 can pull the slider 104 away from the roller 3, so that the knocking ball 105 returns to its original position, and the knocking ball 105 can knock back and forth on the outer wall of the roller 3 through the back and forth movement of the baffle 98.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
