AI Technical Summary
Existing vibratory boxes make it difficult for dust covers and grinding stones to exchange and grind within a wide range of angles within the vibratory plate, resulting in incomplete removal of burrs from some dust covers.
The dust cover production process employs a deburring device that includes a stirring mechanism. The stirring mechanism consists of a stirring blade, a movable shaft, a transmission device, a servo motor, and a cylinder. The servo motor drives the stirring blade to rotate, and the cylinder pushes the movable shaft to rise and fall. Combined with the vibration of the vibrating box, this achieves uniform mixing between the dust cover and the grinding stones.
It effectively eliminates mixing dead zones, ensuring full contact between the dust cover parts and the grinding stone, thus improving the efficiency and thoroughness of burr removal.

Technical Field
[0001] This invention relates to a device for removing burrs during the production of dust covers, belonging to the technical field of dust cover processing equipment. Background Technology
[0002] Dust cover is a general term referring to a protective cover used to cover items to prevent dust, dirt, liquids, scratches or other potential damage; in industrial equipment, dust covers are usually made of various rubber materials using a mold in a one-time injection molding process. When using mold injection molding to form dust covers, when molten plastic (injection molding) or metal (die casting) materials are squeezed into the tiny gaps of the mold under high pressure during the stamping process, a very thin layer of excess material will be formed after cooling and solidification. This is called "flash". In related technologies, the deflashing of large-scale dust covers made of plastic materials is generally carried out by a vibrating box. The vibrating box includes a vibrating plate and a base. The lower end of the vibrating plate is connected to the base by multiple springs arranged in a ring. A vibrating motor is located at the middle of the upper end of the base, and the output end of the vibrating motor is connected to the axis of the vibrating plate. When using this vibratory box to remove burrs from dust covers, place the dust cover parts and grinding stones together in the vibratory plate, then start the vibratory motor. The vibratory motor outputs kinetic energy to make the vibratory plate vibrate. In addition, the lower end of the vibratory plate is connected to the base through multiple springs arranged in a ring. Therefore, when the vibratory motor outputs kinetic energy, the elastic variable generated by the deformation of the springs can improve the vibration effect of the vibratory plate. Ultimately, the dust cover parts inside the vibratory plate and the grinding stones can achieve full contact and mixed friction, which greatly improves the burr removal operation of the dust cover. This vibratory box can perform basic deburring operations on dust covers, but it also has obvious problems and defects. For example, due to the accumulation of dust covers and grinding stones in the vibratory plate, and the fact that the kinetic energy output of the vibratory motor to the vibratory plate is generally small, it is difficult to make the dust covers and grinding stones in the vibratory plate exchange and grind at a wide range of angles, resulting in grinding dead corners and incomplete deburring of some dust covers. Summary of the Invention To solve the above-mentioned technical problems, the present invention provides a dust cover deburring device for dust cover production, which solves the problem in the background art that the vibrating box is difficult to make the dust cover and the grinding stone in the vibrating plate exchange and grind at a wide range of angles, resulting in grinding dead corners and incomplete deburring of some dust covers.
[0003] The technical solution adopted by this invention to solve its technical problem is: A flash removal device for dust cover production, the flash removal device comprising: A stirring mechanism, comprising a stirring component and a driving component, wherein the stirring component is located at the upper end of the driving component; The stirring assembly includes stirring blades and a movable shaft. One end of the movable shaft is connected to the center of the stirring blades, and the other end of the movable shaft is connected to the drive assembly. The drive assembly includes a transmission, a servo motor, and a cylinder. The end of the movable shaft that passes through the transmission is connected to the output end of the cylinder. The output end of the servo motor is located inside the transmission. The cylinder, transmission, and servo motor are arranged in an L-shape.
[0004] Preferably, the cross-section of the stirring blade is installed at an angle to the horizontal line, and the angle between the cross-section of the stirring blade and the horizontal line is controlled between 30 and 45°.
[0005] Preferably, the portion of the movable shaft located inside the transmission is provided with a secondary bevel gear, the axis of which meshes with the outer wall of the movable shaft; the output end of the servo motor located inside the transmission is provided with a main bevel gear, the outer side of which meshes with the outer side of the secondary bevel gear.
[0006] Preferably, the dust cover production deflashing device further includes: a vibrating box and a base, wherein a vibration chamber is formed inside the vibrating box, and a discharge port is connected to one side of the lower end of the vibration chamber; the lower end of the vibrating box is connected to the base through a vibration spring; the stirring blade of the stirring assembly is rotatably installed inside the vibration chamber, and a stop is installed on the part of the movable shaft between the vibrating box and the base; the drive assembly's transmission, servo motor, and cylinder are all located inside the base.
[0007] Preferably, the base is also equipped with a positioning frame, which is located inside the base between the transmission and the cylinder; the movable shaft passes through the transmission and then through the positioning frame to connect with the output end of the cylinder.
[0008] Preferably, a magnetic switch and a timer are also installed on both sides of the cylinder.
[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: Compared with the current method of removing flash from dust cover parts using a vibrating box, the aforementioned flash removal device for dust cover production has the following advantages: It consists of a vibration box and a base, with the lower end of the vibration box connected to the base via a vibration spring. It also includes a stirring mechanism comprising a stirring assembly and a drive assembly. The stirring assembly includes a stirring blade and a movable shaft. One end of the movable shaft is connected to the center of the stirring blade, and the other end is connected to the drive assembly. The drive assembly includes a transmission, a servo motor, and a cylinder. The end of the movable shaft, passing through the transmission, is connected to the output end of the cylinder. The output end of the servo motor is located inside the transmission. The cylinder, transmission, and servo motor are arranged in an L-shape. The vibrating box forms a vibration chamber, and the stirring blades of the stirring assembly are rotated and installed inside the vibration chamber; a stop is installed on the part of the movable shaft between the vibrating box and the base; the transmission, servo motor and cylinder of the drive assembly are all located inside the base; By activating the servo motor, the servo motor outputs kinetic energy, which drives the movable shaft to rotate via the transmission. This, in turn, causes the stirring blades mounted on the movable shaft to rotate, mixing the dust cover and grinding stones placed inside the vibration chamber. During the rotation of the stirring blades, the cylinder can also be activated to output kinetic energy to drive the movable shaft to rise and fall. At intervals, the working height of the stirring blades inside the vibration chamber is adjusted, while the stop blocks reciprocate to impact the vibration box. Since the vibration box and the base are connected by multiple vibration springs, when the stop blocks impact the vibration box, the vibration springs are stretched and elastically deformed, causing the vibration box to vibrate. This causes the dust cover parts and grinding stones at different locations inside the vibration chamber to tumble and mix evenly, eliminating grinding dead corners. As a result, the grinding stones can remove the burrs from different locations on the dust cover. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figure 1-5 The present invention provides a technical solution: A flash removal device for dust cover production, the flash removal device comprising: The stirring mechanism is capable of stirring the dust cover parts and the grinding stone together. During the stirring process, the grinding stone can perform friction polishing on the dust cover parts, i.e., deburring. The stirring mechanism includes a stirring component and a driving component, with the stirring component located at the upper end of the driving component; The stirring assembly includes a stirring blade 3 and a movable shaft 6. One end of the movable shaft 6 is connected to the axis of the stirring blade 3, and the other end of the movable shaft 6 is connected to the drive assembly. The drive assembly includes a transmission 9, a servo motor 10, and a cylinder 12. One end of the movable shaft 6 passes through the transmission 9 and its end portion is connected to the output end of the cylinder 12. The output end of the servo motor 10 is located inside the transmission 9. The cylinder 12, the transmission 9, and the servo motor 10 are arranged in an L-shape. In an embodiment of the present invention, when the stirring mechanism is used to stir the dust cover parts and grinding stones mixed together to achieve the deburring operation of the dust cover parts, the servo motor 10 is started. The servo motor 10 outputs kinetic energy through the transmission 9 to drive the movable shaft 6 to rotate. When the movable shaft 6 rotates, it can drive the stirring blade 3 installed at one end of the movable shaft 6 to rotate, which is used to stir the dust cover parts and grinding stones. During the process of stirring the dust cover parts and grinding stones by rotating the stirring blade 3, the cylinder 12 can also be activated to push the movable shaft 6 up and down at a set time interval. While adjusting the working height position of the stirring blade 3, it can also cause vibration to the tank containing the dust cover parts and grinding stones, which is used to flip the up and down height positions of the dust cover parts and grinding stones respectively, thereby improving the efficiency of the dust cover parts deburring operation. Please refer to Figure 14 for the vibration box. In one embodiment of the present invention, the cross section of the stirring blade 3 is installed at an angle to the horizontal line, and the angle between the cross section of the stirring blade 3 and the horizontal line is controlled to be 30-45°. By designing and installing the stirring blade 3 at an inclined angle, strong axial flow (up and down circulation) and radial flow (pushing outwards towards the tank wall) are generated simultaneously when the stirring blade 3 rotates. This three-dimensional asymmetric flow field can effectively push the material from the top of the tank to the bottom of the tank, and then roll it up from the bottom of the tank, greatly eliminating the mixing dead angle and realizing the rapid and uniform mixing of the dust cover parts and the grinding stone. Please see Figure 5 In one embodiment of the present invention, a secondary bevel gear 16 is provided on the portion of the movable shaft 6 located inside the transmission 9, and the axial position of the secondary bevel gear 16 meshes with the outer wall of the movable shaft 6; a main bevel gear 15 is installed on the portion of the output end of the servo motor 10 located inside the transmission 9, and the outer side of the main bevel gear 15 meshes with the outer side of the secondary bevel gear 16. In an embodiment of the present invention, when the cylinder 12 is started, since the outer wall of the movable shaft 6 is meshed with the axis of the secondary bevel gear 16, when the cylinder 12 outputs kinetic energy, the movable shaft 6 can be pushed to slide along the axis of the secondary bevel gear 16. When the servo motor 10 outputs kinetic energy, it can drive the main bevel gear 15 to rotate. Since the outer side of the main bevel gear 15 meshes with the outer side of the secondary bevel gear 16, the rotation of the main bevel gear 15 will drive the secondary bevel gear 16 to rotate, ultimately causing the movable shaft 6 installed at the axial position of the secondary bevel gear 16 to rotate. Please refer to Figure 14, the vibration chamber. In one embodiment of the present invention, the dust cover production deflashing device further includes: The vibrating box 1 and the base 5 are provided. The vibrating box 1 forms a vibrating cavity 2 inside, and the lower end of the vibrating cavity 2 is connected to the discharge port 7. The lower end of the vibrating box 1 is connected to the base 5 through a vibrating spring 4. The stirring blade 3 of the stirring assembly is rotatably installed inside the vibration chamber 2, and the movable shaft 6 is equipped with a stop 8 on the part between the vibration box 1 and the base 5; the transmission 9, servo motor 10 and cylinder 12 of the drive assembly are all located inside the base 5. In an embodiment of the present invention, when the dust cover production deburring device is used, the dust cover to be processed and the grinding stone are thrown together into the vibration chamber 2 formed by the vibration box 1, and then the servo motor 10 is started. The servo motor 10 outputs kinetic energy to drive the movable shaft 6 to rotate through the transmission 9, thereby causing the stirring blade 3 installed on the movable shaft 6 to rotate, which is used to stir and mix the dust cover and grinding stone put into the vibration chamber 2. During the rotation of the stirring blade 3, the kinetic energy output by the starting cylinder 12 can be used to drive the movable shaft 6 to rise and fall. While adjusting the working height position of the stirring blade 3 inside the vibration chamber 2 at intervals, the baffle 8 can also reciprocate to strike the vibration box 1 at intervals. Since the vibration box 1 and the base 5 are connected by multiple vibration springs 4, when the baffle 8 strikes the vibration box 1, the vibration spring 4 will be stretched and elastically variable, which will cause the vibration box 1 to vibrate. This will cause the dust cover parts and grinding stones at different positions inside the vibration chamber 2 to tumble up and down and mix evenly, so that the grinding stones can remove the burrs at different positions of the dust cover. Please see Figure 4 Specifically, the base 5 is also equipped with a positioning frame 11, which is located inside the base 5 between the transmission 9 and the cylinder 12. The movable shaft 6 passes through the transmission 9 and then through the positioning frame 11 to connect with the output end of the cylinder 12. The positioning frame 11 is used to limit the displacement of the movable shaft 6. Meanwhile, magnetic switches 13 and timers 14 are installed on both sides of cylinder 12. The magnetic switch 13 serves as a position detection sensor for the movable shaft 6; the timer 14 serves as an intermediate delay control unit, instructing the solenoid valve of cylinder 12 to switch, thereby changing the air intake direction of cylinder 12 and realizing the reciprocating motion of the movable shaft 6. The specific process is as follows: When the piston at one end of the movable shaft 6 moves to a specific position, it will trigger the magnetic switch 13. The magnetic switch 13 sends a signal to the controller, which then controls the solenoid valve of the cylinder 12 to switch directions, thereby realizing an infinite cycle of "extending to the end -> retracting -> retracting to the end -> extending again" to complete the reciprocating motion of the movable shaft 6. The workflow of this embodiment is as follows: After the dust cover and grinding stone are put into the vibration chamber 2, the servo motor 10 is started. The servo motor 10 outputs kinetic energy to drive the movable shaft 6 to rotate through the transmission 9, which in turn causes the stirring blade 3 installed on the movable shaft 6 to rotate, so as to stir and mix the dust cover and grinding stone put into the vibration chamber 2. During the rotation of the stirring blade 3, the kinetic energy output by the starting cylinder 12 can be used to drive the movable shaft 6 to rise and fall. While adjusting the working height of the stirring blade 3 inside the vibration chamber 2 at intervals, the baffle 8 can also repeatedly strike the vibration box 1 to cause the vibration box 1 to vibrate, so that the dust cover parts and grinding stones at different positions inside the vibration chamber 2 can roll up and down and mix evenly. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
