Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic packaging bag blow molding technology, and in particular to a plastic packaging bag blow molding device. Background Technology
[0002] A plastic packaging bag blow molding machine is a device used to produce plastic bags and plastic films. It mainly adopts the blow molding process. The principle is that plastic granules are heated and melted under high temperature and high pressure by an extruder, and then drawn out into a tubular shape through a die head. Then, it is cooled and solidified by a cooling air ring. Next, with the help of a traction device, it is stretched to form a flat plastic film or bag. Finally, the film or bag is cut by a cutter to complete the entire molding process.
[0003] In the process of blow molding plastic packaging bags, the inventors have discovered that when plastic granules are injected, they can clog the feed port, causing the device to malfunction. Therefore, we propose a blow molding device for plastic packaging bags. Utility Model Content
[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0005] Specifically, the technical problem to be solved by this utility model is to provide a plastic packaging bag blow molding device to solve the technical problem that plastic particles will block the feed port during the injection of plastic particles, causing the device to malfunction.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0007] A blow molding apparatus for plastic packaging bags includes a frame, the top of which has an integrally formed support plate on which a blow molding machine is mounted;
[0008] The blow molding machine is equipped with a detachable anti-blocking channel via fasteners. Multiple connecting plates are fixedly installed on the inner wall of the anti-blocking channel. A cone block is fixedly installed at the end of the connecting plate away from the anti-blocking channel. The anti-blocking channel is vibrated by a drive device. A feeding hopper is detachably installed at the end of the anti-blocking channel away from the blow molding machine via fasteners.
[0009] As an improved technical solution, a feeding channel is installed at the feed inlet of the blow molding machine. The outer surface of the end of the feeding channel away from the blow molding machine has an integrally formed lower fixing ring. The lower fixing ring has multiple lower fixing holes, and the multiple lower fixing holes are equidistantly arranged along the axial direction of the feeding channel.
[0010] Both ends of the anti-blocking channel have an integrally formed central fixing ring on their outer surfaces. The central fixing ring has multiple central fixing holes, which are equidistant from each other along the axial direction of the anti-blocking channel. The feeding channel and the central fixing ring are fixed together by fasteners that pass through the lower fixing holes and the central fixing ring.
[0011] As an improved technical solution, the bottom outer surface of the hopper has an integrally formed upper fixing ring, the upper fixing ring has multiple upper fixing holes, and the multiple upper fixing holes are equidistantly arranged along the axial direction of the hopper. The upper fixing ring and the middle fixing ring are fixed together by fasteners passing through the upper fixing holes and the middle fixing ring.
[0012] As an improved technical solution, the driving device includes a vibration motor, which is arranged parallel to the anti-blocking channel. A fixing plate is fixedly installed on the outer surface of the anti-blocking channel, and the vibration motor is installed on the inner side of the fixing plate.
[0013] As an improved technical solution, multiple connecting plates are equidistantly arranged along the axial direction of the anti-blocking channel.
[0014] As an improved technical solution, the tip of the cone faces upward, and the central axis of the cone's cross-section coincides with the central axis of the anti-blocking channel's cross-section.
[0015] As an improved technical solution, the fastener consists of a fixing bolt that can pass through the lower fixing hole, the middle fixing hole and the upper fixing hole, and a fixing nut that is threadedly connected to the fixing bolt.
[0016] After adopting the above technical solution, the beneficial effects of this utility model are:
[0017] 1. By injecting plastic granules into the hopper, the granules enter the anti-blocking channel through the hopper's inner cavity. Simultaneously, the vibration motor is started, causing the anti-blocking channel to vibrate. The anti-blocking channel, in turn, vibrates the connecting plate and the cone block, allowing the plastic granules in the anti-blocking channel to smoothly enter the feeding channel and finally into the blow molding machine. The blow molding machine heats and melts the plastic granules under high temperature and pressure, and then draws them out through the die head to form a tubular shape. The tubular shape is then cooled and solidified by a cooling air ring. Next, with the help of the traction device, the plastic granules are stretched to form a flat bag. This effectively prevents the plastic granules from clogging at the feeding port, thereby improving processing efficiency.
[0018] 2. By assembling the anti-clogging channel onto the blow molding machine and using fasteners, the middle fixing ring and the lower fixing ring are in contact, and the lower fixing hole and the middle fixing hole are coaxial. The fixing bolt passes through the lower fixing hole and the middle fixing hole, and the middle fixing ring and the lower fixing ring are fixed together using a fixing nut. Then, the hopper is assembled onto the anti-clogging channel and assembled together using fasteners. At this time, the middle fixing ring and the upper fixing ring are in contact, and the upper fixing hole and the middle fixing hole are coaxial. The fixing bolt passes through the upper fixing hole and the middle fixing hole, and the middle fixing ring and the upper fixing ring are fixed together using a fixing nut. This process is repeated until the assembly is complete. If the anti-clogging channel needs to be disassembled, the above steps are reversed, making it convenient to assemble and disassemble the anti-clogging channel, and the operation is simple and quick.

[0035] Reference Figure 1 , Figure 2 as well as Figure 4 The driving device includes a vibration motor 7, which is arranged parallel to the anti-blocking channel 3. A fixing plate 6 is fixedly installed on the outer surface of the anti-blocking channel 3, and the vibration motor 7 is installed on the inner side of the fixing plate 6 so as to drive the anti-blocking channel 3 to vibrate, thereby preventing the anti-blocking channel 3 from being blocked.

If it is necessary to disassemble the anti-blocking channel 3, the above steps can be reversed, which makes it convenient to disassemble and assemble the anti-blocking channel 3 and the operation is simple and quick.
[0040] Next, plastic granules are injected into the feeding hopper 8. At this time, the plastic granules enter the anti-blocking channel 3 through the inner cavity of the feeding hopper 8. At the same time, the vibration motor 7 fixed on the fixed plate 6 is started. The vibration motor 7 drives the anti-blocking channel 3 to vibrate, and the anti-blocking channel 3 drives the connecting plate 4 and the cone block 5 to vibrate, so that the plastic granules in the anti-blocking channel 3 can smoothly enter the feeding channel 201 and finally enter the blow molding machine 2. The blow molding machine 2 heats and melts the plastic granules under high temperature and high pressure, and leads them out into a formed tube through the die head.
