Description

Technical Field

[0001] This utility model relates to the technical field of zipper production equipment, and in particular to a zipper head screening device. Background Technology

[0002] Zipper heads are typically produced through injection molding or die casting. Multiple zipper heads can be produced in a single injection molding or die casting process, but these heads are all connected to sprue material, requiring separation and screening. Existing screening devices mainly rely on screening drums to separate and screen the zipper heads from the sprue material. A screen plate is installed on one side of the screening drum. After placing the zipper head and sprue material inside, the drum rotates, causing the zipper head to separate from the sprue material and fall out through the screen plate. However, sprue material is usually long and narrow, and during drum rotation, there is still a chance that some sprue material will fall out, leading to a mixture of zipper heads and sprue material after screening. Summary of the Invention

[0003] This utility model mainly solves the above-mentioned problems by providing a zipper head screening device that can perform two screenings, reducing the situation where zipper heads and sprue material are mixed after screening.

[0004] The technical solution adopted by this utility model to solve its technical problem is a zipper head screening device, including a frame, a screening roller, a discharge plate, a screening frame, a receiving frame, and a drive motor. The screening roller is rotatably arranged on the upper part of the frame, the discharge plate is rotatably arranged in the middle of the frame, and a spring support mechanism is slidably arranged on the side of the discharge plate. The screening frame is slidably arranged in the lower part of the frame, and the receiving frame is slidably arranged at the bottom of the frame. The drive motor drives the screening roller to roll and the screening frame to reciprocate through a transmission mechanism.

[0005] As a preferred embodiment of the above solution, the blanking plate includes a plate body and rotating columns disposed on both sides of one end of the plate body.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below through embodiments and in conjunction with the accompanying drawings.

[0019] Example:

[0020] This embodiment provides a zipper head screening device, such as... Figure 1 and Figure 2 As shown, the system includes a frame 1, a screening drum 2, a discharge plate 3, a screening frame 4, a receiving frame 5, and a drive motor. The screening drum 2 is rotatably mounted on the upper part of the frame 1, the discharge plate 3 is rotatably mounted in the middle of the frame 1, and a spring support mechanism is slidably mounted on the side of the discharge plate 3. The screening frame 3 is slidably mounted on the lower part of the frame, and the receiving frame 5 is slidably mounted on the bottom of the frame. The receiving frame 5 is equipped with a handle for easy pulling out. The drive motor drives the screening drum 2 and the screening frame 4 to reciprocate through a transmission mechanism.

[0021] The screening drum 1 is cylindrical, and in this embodiment, it is a hexagonal prism. An opening is provided on one side of the screening drum 1, and a detachable screen plate is mounted on the opening. Injection-molded or die-cast products are placed into the screening drum 1 through the opening. After the screen plate is installed, the screening drum is rotated by a drive motor to separate the zipper head from the sprue material. During the rotation of the screening drum, whenever the opening faces downwards, the zipper head separated from the sprue material can fall through the screen plate onto the discharge plate. In this process, because the sprue material is elongated, there is a certain probability that the sprue liquid can fall through the screen plate onto the discharge plate.

[0022] like Figure 3 As shown, the discharge plate 3 includes a plate body 18 and rotating columns 17 located on both sides of one end of the plate body 18. The plate body 18 is rotatably connected to the frame through the rotating columns 17. Each side of the plate body 18 near the rotating columns is provided with a first sliding groove 12. The spring support mechanism is slidably connected to the plate body through the first sliding groove. The spring support mechanism includes a support plate 15, a spring 14, and a sliding column 13. The support plate 15 is fixedly installed on the outer wall of the frame. One end of the spring 14 is fixedly installed on the support plate 15, and the other end of the spring 14 is connected to the sliding column 13. The sliding column 13 passes through the side wall of the frame and is slidably connected to the first sliding groove 12 on the discharge plate. In addition, a pressure sensor 16 is provided between the support plate and the spring. In this embodiment, the right end of the discharge plate 3 is rotatably connected to the frame and is tilted and rotated from left to right under the action of the spring support mechanism. When the zipper head and a small amount of sprue material fall from the screening roller, the zipper head and a small amount of sprue material fall to the right half of the discharge plate and fall along the discharge plate into the screening frame. The discharge plate can be regarded as a lever with the fulcrum on the right end, and the spring support mechanism has a large lever arm. Therefore, when the zipper head and sprue material fall onto the discharge plate, the pressure sensor can detect a large pressure. Based on this, it can detect whether there is an object falling into the screening drum. After the screening drum has not dropped any object for a period of time, the screening drum can be stopped to rotate, thereby achieving energy saving and emission reduction.

[0023] The bottom surface of the screening frame 4 is provided with several screen holes, and the side surface of the screening frame 4 is provided with sliding blocks 10. The side wall of the frame 1 is provided with a second sliding groove 9. The sliding block 10 is slidably connected to the second sliding groove 9 and extends out of the second sliding groove 9. The drive motor is connected to the sliding block through a transmission mechanism. The transmission mechanism includes a drive wheel 6, a driven wheel 7, a transmission belt 8, and a connecting rod 11. The drive wheel 6 is connected to the drive motor, and the driven wheel 7 is connected to the screening drum. The drive wheel 6 and the driven wheel 7 are driven by the transmission belt 8. One end of the connecting rod 11 is rotatably mounted on the drive wheel 6, and the other end of the connecting rod 11 is rotatably connected to the sliding block 10. When the drive motor is running, the drive motor drives the drive wheel to rotate, and the drive wheel drives the driven wheel to rotate through the rotating belt, which in turn drives the screening drum to rotate. In addition, the drive wheel, connecting rod, and sliding block form a crank-slider mechanism, which converts the rotation output by the drive motor into the translation of the sliding block, thereby causing the screening frame to continuously reciprocate and translate to achieve secondary screening. After secondary screening, the zipper head falls through the screen holes on the bottom of the screening frame into the receiving frame 5, while the sprue material remains in the screening frame.

[0024] The zipper head screening device in this embodiment performs secondary screening of zipper heads and sprue material through screening drum and screening frame, which can reduce the situation of zipper heads and sprue material being mixed after screening. It is equipped with spring support mechanism and pressure sensor. The pressure sensor can detect whether there is an object falling on the screening drum so as to stop the machine in time and reduce energy waste.
