Description

Technical Field

[0001] This utility model relates to the field of preform dust removal, and in particular to a preform rotary dust removal device. Background Technology

[0002] Preforms are formed by injection molding, where raw materials are filled into a mold under specific temperature and pressure conditions and the preform is formed under the working conditions of an injection molding machine. After injection molding, it becomes an intermediate semi-finished product, and then it is blow molded into an end product.

[0003] CN217857864U discloses a dust removal and turning device for bottle preforms, which includes a support base, a fixed platform fixedly connected to the top of the support base, a support column fixedly connected to the center of the top of the fixed platform, and multiple dust removal devices on the outer wall of the top of the support column. The dust removal device includes a support frame that uses dust removal devices and mechanical clamps to fix the bottle preform with the bottle mouth facing upward. An electric actuator causes a telescopic rod to extend and retract, which drives a rotating motor. The rotating motor drives a rotating rod, which rotates the cleaning cotton board and dust removal soft head on the surface to reach the bottom of the bottle, performing the first dust removal on the inside of the bottle preform. The drive motor then turns the bottle preform fixed on the mechanical clamp so that the bottle mouth faces downward. A fan then blows out the internal dust. The process is repeated to make the inside of the bottle preform cleaner and to improve the dust removal efficiency.

[0004] Although the aforementioned dust removal and turning device for bottle preforms has certain advantages in dust removal capabilities, it still requires manual loading and unloading of bottle preforms by workers, which is inefficient and labor-intensive. In particular, when continuous mass production is required, manual loading and unloading will become a production bottleneck. Utility Model Content

[0025] Chinese utility model patent with publication number CN216032410U discloses a plastic preform stretching device with a clamping structure. The device consists of a machine base, a motor, a lead screw, a first slide, a support base, a drive motor, a drive assembly, a clamping platform, and an auxiliary clamping plate. The preform is placed on two clamping platforms. The drive motor drives the drive rod to move clockwise. The drive rod quickly adjusts the two push rods so that the two clamping platforms can quickly clamp the preform. The auxiliary clamping plate, in conjunction with a spring, improves the clamping effect between the clamping platform and the preform.

[0026] The clamping component 45 can use the clamping mechanism of the above-mentioned patent to clamp and fix the preform, ensuring that it will not slide or shift during the dust removal process.

[0027] Please see Figure 4 and Figure 5 This utility model provides a rotary dust removal device for bottle preforms. The dust removal structure 5 includes a scissor-type telescopic frame 51, a housing 52, a second motor 53, a second rotating shaft 54, a worm 55, a worm wheel 56, and a dust removal brush 57. The housing 52 is installed on the upper end face of the scissor-type telescopic frame 51, and the second motor 53 is installed on the left end face of the housing 52. The output end of the second motor 53 extends into the housing 52 and is connected to one end of the second rotating shaft 54. The other end of the second rotating shaft 54 ​​is rotatably connected to the inner wall of the housing 52 through a bearing. The worm 55 is fitted on the outer side of the second rotating shaft 54 ​​and is meshed with the worm wheel 56. The dust removal brush 57 is fitted on the inner wall of the worm wheel 56. The lower end of the dust removal brush 57 is rotatably connected to the inner wall of the housing 52 through a bearing, and the upper side of the dust removal brush 57 extends out of the housing 52. The scissor-type telescopic frame 51 is located on the rear side of the mounting base 41.

[0028] The working principle is as follows:

[0029] First, place the new device in the desired location and connect the circuitry.

[0030] Second, the preform is first correctly placed on the placement rack 32. Since the placement rack 32 is set to an inclined state, the preform will slide to the left. The limiting structure 35 can block the preform and flip the clamping component 45 to avoid motion interference. The conveyor belt 1 is controlled to operate. The conveyor belt 1 drives the transmission shaft 37 to rotate through the pulley group 2. The transmission shaft 37 drives the second bevel gear 36 to rotate. The second bevel gear 36 drives the first bevel gear 34 to rotate. The first bevel gear 34 drives the third rotating shaft 351 to rotate. The third rotating shaft 351 drives the rotating block 352 to rotate. The rotating block 352 drives the fixed plate 353 to rotate. The fixed plate 353 drives the limiting plate 354 to rotate. After the conveyor belt 1 moves a certain distance, a preform is released by the rotation of the limiting plate 354. The preform is guided and buffered by the guide plate 38, so that the preform moves to the upper end of the conveyor belt 1.

[0031] Third, since the position of the bottle preform is matched with the position of the gripper of the clamping component 45, after the bottle preform is moved into place, the operation of the conveyor belt 1 is stopped, the clamping component 45 is controlled to flip and reset, the gripper of the control component 45 clamps and fixes the bottle preform, the first motor 43 is controlled to rotate, and the output end of the first motor 43 drives the clamping component 45 to flip 180 degrees again through the first rotating shaft 44.

[0032] Fourth, by controlling the extension of the scissor-type telescopic frame 51, the outer shell 52 is raised, allowing the dust removal brush 57 to be inserted into the preform. The second motor 53 is then operated, and its output drives the second rotating shaft 54 ​​to rotate. The second rotating shaft 54 ​​drives the worm gear 55 to rotate, which in turn drives the worm wheel 56 to rotate. The worm wheel 56 then drives the dust removal brush 57 to rotate, thus removing dust from the inside of the preform. The dust and impurities are then collected by an external vacuum cleaner. After dust removal, the dust removal structure 5 is reset, and the clamping assembly 45 places the preform back onto the upper surface of the conveyor belt 1 and flips it again. This allows the conveyor belt 1 to transport the dust-removed preform from the left side to the next process step, while the remaining un-dusted preforms are continuously transported. This achieves continuous dust removal of the preforms, facilitating loading and unloading, improving production efficiency, and reducing labor intensity.
