Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, and in particular to an automatic preform feeding device for blow molding machines. Background Technology

[0002] In the plastic bottle manufacturing industry, blow molding machines are the core equipment for realizing the blow molding of bottle preforms, and the performance of automatic preform feeding devices, as a key component of blow molding machines, directly affects production efficiency and product quality.

[0003] Traditional preform feeding devices are prone to vibration and jamming during operation. Due to uneven friction and track tolerances on components such as the feeding disc and turntable, preforms are easily misaligned and squeezed together, leading to conveying interruptions, frequent shutdowns for adjustments, and severely impacting production continuity. This is especially true for thin-walled and irregularly shaped preforms, where conventional conveying structures struggle to ensure stable transport, resulting in a higher preform breakage rate. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the conveying mechanism of the preform feeding device is prone to shaking and jamming during operation, and the bottle preforms are prone to positional deviation and mutual compression on the preform feeding plate, turntable and other components due to uneven friction and track tolerance, resulting in conveying interruption, frequent machine stoppage for adjustment, and serious impact on production continuity. Therefore, an automatic preform feeding device for blow molding machines is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic preform feeding device for a blow molding machine, comprising a preform feeding disc, an arc hole on the surface of the preform feeding disc, an arc groove on the top of the preform feeding disc, heating arc plates fixedly connected to the inner walls on both sides of the arc groove, a convex groove on the top of the preform feeding disc near the center, a drive motor embedded and fixedly connected inside the convex groove, a turntable fixedly connected to the output end of the drive motor, and grooves evenly spaced on the surface of the turntable near the edge; and a blow molding assembly, the blow molding assembly being fixedly installed inside the arc hole.

[0006] Preferably, the bottom of the embryo feeding disc is fixedly connected to four support columns.

[0007] Preferably, the groove is located above the arc groove.

[0008] Preferably, the blow molding assembly includes a movable mold and a fixed mold, both of which are located inside an arc hole. An electric push rod is fixedly connected to one side of the arc wall of the arc hole, and the output end of the electric push rod is fixedly connected to the movable mold. The blow molding machine body is fixedly installed on the top of the fixed mold.

[0009] Preferably, both ends of the fixed mold are fixedly connected to a fixed plate, and the other end of the fixed plate is fixedly connected to the inner wall of the arc hole.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, a stable preform conveying track is formed through the structural design of the preform infeeding tray, turntable, and arc grooves and recesses, reducing vibration and jamming during preform conveying. Simultaneously, the support columns ensure the overall stability of the device, and the arc holes and fixing plates work together to limit the position of the components, ensuring the preforms maintain a regular posture during conveying. Even for thin-walled and irregularly shaped preforms, stable and continuous conveying can be achieved, reducing preform breakage rates, ensuring uninterrupted production, and improving production efficiency. At the same time, the heating arc plate provides precise regional heating of the preforms on the turntable, and the arc grooves guide the heating to ensure uniformity. Attached Figure Description
