Description

Technical Field

[0001] This utility model relates to the technical field of plastic product processing equipment, specifically a feeding structure for a bag making machine used for PE bag processing. Background Technology

[0002] In the automated production process of PE (polyethylene) bags, the bag making machine is the core equipment. Its feeding structure is responsible for stably and evenly conveying PE raw material granules (usually a mixture of virgin material, recycled material and additives such as color masterbatch) to the extruder. The extruder heats, melts, and pressurizes the uniformly plasticized melt into the mold, and finally blow-molded or calendered it into a film to make a plastic bag.

[0003] However, the main function of the current feeding structure extrusion auger is conveying and melting, with limited mixing capacity and a unidirectional piston flow, resulting in extremely poor axial mixing. For various raw materials with large differences in density and particle size (such as virgin materials and recycled materials, color masterbatches), stratification or uneven dispersion can easily occur in the storage hopper and extruder, leading to problems such as uneven color, crystal points, fish eyes, or inconsistent physical properties in the final PE bags. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding structure for a bag making machine for PE bag processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A feeding structure for a bag-making machine used in PE bag processing includes:

[0007] The pre-mixing structure includes a cap, the bottom of which is rotatably mounted with a feeding auger;

[0008] A storage tank, including a tank body, wherein the upper opening of the tank body and the cover engage with each other;

[0009] The feeding extrusion structure includes an extrusion tube, one end of which is connected to the lower end of the tank.

[0010] Furthermore, the sealing cover has several locking hooks arranged in a ring at equal angles on its side surface, and lifting rings are fixedly installed on both sides of the upper surface of the sealing cover.

[0011] Furthermore, a No. 1 motor is fixedly installed in the middle of the upper surface of the cover, and the output end of the No. 1 motor is fixedly connected to the upper end of the feeding auger. The diameter of the upper half blade of the feeding auger is twice the diameter of the lower half blade.

[0012] Furthermore, several pull buckles are fixedly installed in a ring at equal angles on the upper edge of the side surface of the tank, and a feeding hopper is fixedly installed at the bottom of the tank, with a heating resistance wire embedded inside the feeding hopper.

[0013] Furthermore, several heat insulation sleeves are fixedly installed in the middle of the extrusion tube, and electromagnetic coils are wound inside the heat insulation sleeves, with each electromagnetic coil connected in series.

[0014] Furthermore, an extrusion auger is rotatably installed inside the extrusion tube, a heat insulation block is fixedly installed at one end of the extrusion tube, a second motor is fixedly installed on one side of the heat insulation block, and the output end of the second motor passes through the heat insulation block and is fixedly connected to the extrusion auger.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The entire device is fixedly installed at the raw material inlet of the bag making machine. One end of the extrusion tube is connected to the extrusion molding die. When in use, the various raw material granules are first poured into the tank, and then the cover is closed so that the feeding auger is inserted into the tank. The feeding auger is rotated in the opposite direction to continuously lift the raw material in the middle, so that a cavity is formed in the middle of the bottom layer. The raw material on the outer side of the bottom flows into the middle of the bottom side. The lifted material in the middle is squeezed into the outer side of the upper layer, realizing continuous turning and pre-stirring of the various raw materials fed in, avoiding relying entirely on the extrusion auger for mixing and improving the mixing effect.

[0017] The material fed into the extrusion tube by the feeding hopper is transported forward by the extrusion auger driven by motor No. 2. During the transport process, the extrusion auger is used for further mixing. At the same time, the extrusion auger is induction heated in sections by electromagnetic coils. The extrusion auger then completely melts the material and finally sends it to the extrusion die. This process achieves segmented mixing and segmented heating, improving the mixing effect while optimizing energy consumption efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 In this embodiment of the utility model, a feeding structure for a bag making machine for PE bag processing includes a pre-mixing structure 1, a storage tank 2, and a feeding extrusion structure 3. The pre-mixing structure 1 includes a cover 101, and a feeding auger 105 is rotatably installed at the bottom of the cover 101. The storage tank 2 includes a tank body 201, and the upper opening of the tank body 201 is engaged with the cover 101. The feeding extrusion structure 3 includes an extrusion tube 301, and one end of the extrusion tube 301 is connected to the lower end of the tank body 201.

[0025] Specifically, the entire device is fixedly installed at the raw material inlet of the bag making machine. One end of the extrusion tube 301 is connected to the extrusion molding die. In use, the various raw material granules are first poured into the tank 201, and then the cover 101 is closed so that the feeding auger 105 is inserted into the tank 201. The feeding auger 105 is rotated in the opposite direction to continuously lift the raw material in the middle, so that a cavity is formed in the middle of the bottom layer. The raw material on the outer side of the bottom flows into the middle of the bottom side. The lifted material in the middle is squeezed into the outer side of the upper layer, realizing continuous turning and pre-stirring of the various raw materials fed in, avoiding complete reliance on the extrusion auger 304 for mixing and stirring, and improving the mixing effect. Example

[0026] like Figure 1As shown, in this embodiment, a number of locking hooks 102 are fixedly installed in a ring at equal angles on the side surface of the cover 101, and lifting rings 103 are fixedly installed on both sides of the upper surface of the cover 101; a No. 1 motor 104 is fixedly installed in the middle of the upper surface of the cover 101, and the output end of the No. 1 motor 104 is fixedly connected to the upper end of the feeding auger 105. The diameter of the upper half blade of the feeding auger 105 is twice the diameter of the lower half blade; a number of pull buckles 202 are fixedly installed in a ring at equal angles on the upper edge of the side surface of the tank body 201, and a feeding hopper 203 is fixedly installed at the bottom of the tank body 201. A heating resistance wire 204 is embedded inside the feeding hopper 203.

[0027] In this embodiment, the lifting ring 103 is connected to the lifting structure such as the sling to realize opening and closing. When the cover 101 and the tank 201 are closed, they are locked by the buckle 202 and the locking hook 102. The narrower lower half of the feeding auger 105 is inserted into the bottom outlet of the feeding hopper 203. After the stirring work is completed, the feeding auger 105 is rotated in the forward direction and the lower half of the feeding auger 105 is used for auxiliary feeding. Before feeding, the heating resistance wire 204 is energized to generate heat to preheat the raw materials. Example

[0028] Based on Example 1, in order to supplement the specific method of completely melting and extruding the material through the feeding extrusion structure 3, which was not mentioned in Example 1, this method is proposed.

[0029] like Figure 4 As shown, in this embodiment, several heat insulation sleeves 302 are fixedly installed in the middle of the extrusion tube 301. Electromagnetic coils 303 are wound inside the heat insulation sleeves 302, and each electromagnetic coil 303 is connected in series with the others. An extrusion auger 304 is rotatably installed inside the extrusion tube 301. A heat insulation block 305 is fixedly installed at one end of the extrusion tube 301. A second motor 306 is fixedly installed on one side of the heat insulation block 305. The output end of the second motor 306 passes through the heat insulation block 305 and is fixedly connected to the extrusion auger 304.

[0030] In practice, the material fed into the extrusion tube 301 by the feeding hopper 203 is transported forward by the extrusion auger 304 driven by the second motor 306. During the transport process, the extrusion auger 304 is used for further mixing. At the same time, the extrusion auger 304 is induction heated in stages by the electromagnetic coil 303. The extrusion auger 304 then completely melts the material and finally sends it to the extrusion die. This achieves staged mixing and staged heating, improving the mixing effect while optimizing energy consumption efficiency.
