Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing technology, and more specifically, to a deburring device for plastic sheets. Background Technology

[0002] Dry ice polishing equipment, commonly known as dry ice blasting cleaning machines or dry ice deburring machines, removes burrs by high-speed blasting of dry ice particles, utilizing both low-temperature embrittlement and kinetic impact. An existing publication (CN207874001U) describes an automatic dry ice deburring device, whose structure includes a frame, a dry ice granulator mounted on the frame, and a four-axis robot; it also includes a dry ice supply pipe connected to the dry ice granulator, and a spray gun connected to the four-axis robot drive; the dry ice supply pipe is connected to the spray gun; and it includes a masking fixture for holding several silicone products, with a work platform on the frame where the masking fixture is placed; the spray gun is positioned above the masking fixture.

[0003] However, in the above solution, when the spray gun sprays dry ice to remove burrs from the workpiece, some irregularly shaped dry ice can easily accumulate in the inner cavity of the spray gun, which can easily cause blockage. Blockage may cause a sudden increase in internal pressure of the nozzle, resulting in deformation or breakage of the spray gun. Utility Model Content

[0004] The main purpose of this utility model is to provide a deburring device for plastic sheets, which can effectively solve the problem in the background art where some irregularly shaped dry ice can easily accumulate in the inner cavity of the spray gun when spraying dry ice to remove burrs from the workpiece, which can easily cause blockage. Blockage may lead to a sudden increase in internal pressure of the nozzle, causing the spray gun to deform or break.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A deburring device for plastic sheets includes a support base, on the upper surface of which a dry ice pelletizer is mounted. A nozzle is fixedly installed at the output end of the dry ice pelletizer via a corrugated pipe. An installation ring is fitted on the outer wall of the nozzle. A handle is fixedly installed on the outer wall of the installation ring. A vibration transmission component is provided on the outer wall of the nozzle. A striking component for striking is provided on one side of the installation ring.

[0007] Preferably, the delivery assembly includes several copper rods, each of which is fixedly installed through the outer wall of the nozzle, and a first annular copper plate is fixedly installed at one end of each of the copper rods.

[0008] Preferably, the striking assembly includes a plurality of slide bars, each slide bar being slidably disposed through one side of the mounting ring, a spherical block being fixedly mounted at one end of each slide bar, and a limit ring being fixedly mounted at the other end of each slide bar;

[0009] Each of the slide rods is fitted with a positioning ring on the side near the spherical block, and each of the slide rods is fitted with a spring that can be compressed and reset on the side near the positioning ring.

[0010] Preferably, a second annular copper plate is fixedly installed at the other end of each of the copper rods.

[0011] Preferably, a support plate is fitted onto the surface of the grip, a motor is fixedly mounted on one side of the upper surface of the support plate, and a rotating block is fixedly mounted on the output shaft of the motor.

[0012] A push plate is fixedly installed on the outer wall of the limiting ring via a connecting frame.

[0013] Preferably, a support frame is fixedly installed on the surface of the dry ice pellet machine, and a slot is opened on one side of the upper surface of the support frame, with the handle interlocking with the slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) During dry ice transport, the operator controls the movement of the slide bar to move the spherical block. The spring is compressed by the force. Then the operator releases the slide bar, the spring returns to its original position and moves the spherical block in the opposite direction, so that the spherical block can strike the first annular copper plate. The resulting vibration is transmitted to the dry ice inside the nozzle through the copper rod. This process is repeated, causing the dry ice to vibrate and separate from the adjacent dry ice, thereby avoiding blockage and preventing damage to the nozzle. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-8 As shown, a deburring device for plastic sheets includes a support base 1. A dry ice pelletizer 2 is disposed on the upper surface of the support base 1. A nozzle 3 is fixedly installed at the output end of the dry ice pelletizer 2 through a corrugated pipe 201. An installation ring 4 is sleeved on the outer wall of the nozzle 3. A handle 5 is fixedly installed on the outer wall of the installation ring 4. A transmission component 6 for transmitting vibration is disposed on the outer wall of the nozzle 3. A striking component 7 for striking is disposed on one side of the installation ring 4.

[0027] The transfer component 6 includes several copper rods 601, each of which is fixedly installed through the outer wall of the nozzle 3, and a first annular copper plate 602 is fixedly installed at one end of each copper rod 601.

[0028] The striking component 7 includes several slide rods 701, each slide rod 701 is slidably disposed on one side of the mounting ring 4, a ball block 702 is fixedly installed at one end of each slide rod 701, and a limit ring 703 is fixedly installed at the other end of each slide rod 701.

[0029] Each slide rod 701 has a positioning ring 704 fitted on the side of its shaft near the spherical block 702, and each slide rod 701 has a spring 705 that can be compressed and reset on the side of its shaft near the positioning ring 704.

[0030] The operator starts the dry ice pelletizer 2 to produce small dry ice pellets, which are then pumped through a bellows 201 to the nozzle 3. The nozzle 3 sprays the dry ice onto the workpiece to remove burrs. During the dry ice transport, the operator controls the slide bar 701 to move, causing the spherical block 702 to move. The spring 705 is compressed. Then, the operator releases the slide bar 701, the spring 705 returns to its original position, and the spherical block 702 moves in the opposite direction, striking the first annular copper plate 602. The resulting vibration is transmitted to the dry ice inside the nozzle 3 through the copper rod 601. This process is repeated, causing the dry ice to vibrate and separate from adjacent dry ice particles, thus preventing blockage and damage to the nozzle 3.

[0031] In another embodiment of this utility model, a second annular copper plate 8 is fixedly installed at the other end of each copper rod 601.

[0032] By setting a second annular copper plate 8, the vibration transmission area is increased, thus improving the unblocking effect.

[0033] In another embodiment of the present invention, a support plate 9 is sleeved on the surface of the grip 5, a motor 10 is fixedly installed on one side of the upper surface of the support plate 9, and a rotating block 11 is fixedly installed on the output shaft of the motor 10.

[0034] The outer wall of the limiting ring 703 is fixedly mounted with a push plate 1201 via a connecting bracket 12.

[0035] The operator starts the motor 10, causing its output shaft to drive the rotating block 11 to rotate. The rotating block 11 pushes the push plate 1201, causing the slide bar 701 to move. The spring 705 is compressed. As the rotating block 11 continues to rotate, it disengages from the push plate 1201, allowing the spring 705 to return to its original position. The spherical block 702 can then perform its striking function. As the output shaft of the motor 10 continues to rotate, high-frequency vibration is achieved. The operator does not need to manually move the slide bar 701, thus reducing the operator's workload.

[0036] In another embodiment of this utility model, a support frame 13 is fixedly installed on the surface of the dry ice pellet machine 2, and a slot 14 is opened on one side of the upper surface of the support frame 13, and the handle 5 is inserted into the slot 14.

[0037] By setting up a support frame 13 with slots 14, it is convenient for staff to store the nozzles 3, and the nozzles 3 are prevented from being trampled on when placed on the ground.

[0038] The working principle of this deburring device for plastic sheets:

[0039] In use, the operator starts the dry ice pellet machine 2 to produce small dry ice pellets, which are then transported to the nozzle 3 through the bellows 201 via a delivery pump. The nozzle 3 then sprays the dry ice onto the workpiece to remove burrs. During the dry ice transport, the operator controls the slide bar 701 to move, causing the spherical block 702 to move. The spring 705 is compressed under force. Then, the operator releases the slide bar 701, the spring 705 returns to its original position, and the spherical block 702 moves in the opposite direction, allowing it to strike the first annular copper plate 602. The resulting vibration is transmitted to the dry ice inside the nozzle 3 through the copper rod 601. This process is repeated, causing the dry ice to vibrate and separate from adjacent dry ice particles, thus preventing blockage and damage to the nozzle 3.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
