Description

Technical Field

[0001] This utility model relates to the field of plastic packaging barrels, and in particular to a multi-layer composite high-strength polymer plastic packaging barrel. Background Technology

[0002] Plastic packaging drums are containers used for transporting or storing various liquids. They are mostly used to hold liquids in industries such as chemicals, pesticides, pharmaceuticals, food, hardware, electronics, and electromechanical products. Plastic packaging drums have excellent properties, such as being unbreakable, rust-free, lightweight, and having excellent oil and strong corrosion resistance.

[0003] Most existing plastic packaging buckets are made of polyethylene, polypropylene, and other plastics through blow molding and injection molding. They lack impact resistance and are easily deformed and damaged when subjected to external impact. In addition, most existing plastic packaging buckets have a pouring spout at the top of the bucket to drain the liquid inside. However, at the moment of pouring, due to the weight of the liquid and the impact force generated during the pouring process, liquid splashing often occurs. This not only causes waste, but if the poured liquid is corrosive, it can also cause personal injury.

[0004] Therefore, those skilled in the art have provided a multi-layer composite high-strength polymer plastic packaging barrel to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-layer composite high-strength polymer plastic packaging bucket. By setting anti-collision and buffer structures, the anti-collision capability of the plastic packaging bucket is enhanced, extending its service life. By setting a slow-flow cover, the speed of liquid outflow during pouring is slowed down, preventing liquid from spraying out from the outlet pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite high-strength polymer plastic packaging barrel, comprising a barrel body, the barrel body comprising an inner barrel, a support layer fixedly disposed on the outer side of the inner barrel, a buffer structure disposed inside the support layer, the buffer structure comprising two symmetrical air chambers, springs fixedly disposed on the inner walls of the upper and lower sides of the two air chambers, and a piston fixedly disposed on the other end of the springs, the piston being slidably sleeved inside the air chambers;

[0007] An anti-collision structure is fixedly installed on the outside of the support layer. The anti-collision structure includes multiple anti-collision tubes. The multiple anti-collision tubes are divided into upper and lower groups and a connecting tube is fixedly sleeved near the buffer structure. A gas guide tube is fixedly sleeved on the side of the connecting tube near the support layer. The other end of the gas guide tube passes through the support layer and leads to the inside of the air chamber. The end of the gas guide tube leading to the inside of the air chamber is located between two pistons.

[0008] Furthermore, the outer side of the anti-collision structure is provided with an outer shell, which is fixedly connected to the anti-collision tube.

[0009] Furthermore, a flow-slowing cover is threaded onto the upper end of the barrel body. The flow-slowing cover includes a barrel lid, and a flow-slowing cavity is opened inside the barrel lid. A fixed shaft is fixedly installed between the inner walls on both sides of the flow-slowing cavity, and a fan wheel is rotatably installed on the shaft of the fixed shaft.

[0010] Furthermore, a funnel groove is provided at the lower end of the bucket lid, and a flow groove is provided at the bottom of the funnel groove, which is connected to the slow flow cavity.

[0011] Furthermore, a liquid outlet pipe is fixedly sleeved on the upper end of the bucket lid, the liquid outlet pipe is connected to the slow flow chamber, and a sealing cap is threaded onto the upper end of the liquid outlet pipe.

[0012] Furthermore, a handle is fixedly provided at the center of the upper end of the bucket lid, and a support ring is fixedly provided at the upper edge of the bucket lid. The support ring has a notch near the sealing cover, and the upper surface of the support ring is flush with the upper surface of the handle and the upper surface of the sealing cover.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model proposes a multi-layer composite high-strength polymer plastic packaging bucket. By setting up an anti-collision structure and a buffer structure, when the outer shell of the plastic packaging bucket is impacted and squeezed, the stress point of the outer shell will squeeze the anti-collision tube. The air inside the anti-collision tube is squeezed and enters the air chamber through the air guide tube, pushing two pistons. When the external force disappears, the piston, under the action of the spring, squeezes the gas that entered the air chamber from the inside of the anti-collision tube and expels it from the air chamber. The gas then enters the anti-collision tube through the air guide tube. Thus, the anti-collision tube supports the outer shell and restores its original shape, effectively preventing the plastic packaging bucket from deforming and being damaged after being impacted and squeezed.

[0015] 2. The multi-layer composite high-strength polymer plastic packaging bucket proposed in this utility model has a slow-flow cover. When liquid is poured, the liquid flows into the slow-flow chamber through the flow channel and drives the fan wheel to rotate. Since the flow channel has a turning angle near the slow-flow chamber, the speed at which the liquid flows into the slow-flow chamber is slowed down. In addition, the flow velocity of the liquid will decrease again when it drives the fan wheel to rotate, which slows down the high flow velocity generated by the liquid due to gravity and the impact force of pouring, thereby effectively preventing the liquid from spraying directly out of the liquid outlet pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Reference Figure 1-6 One embodiment provided by this utility model:

[0026] A multi-layer composite high-strength polymer plastic packaging barrel includes a barrel body 1, the barrel body 1 includes an inner barrel 101, a support layer 102 is fixedly disposed on the outer side of the inner barrel 101, a buffer structure 105 is disposed inside the support layer 102, the buffer structure 105 includes two vertically symmetrical air chambers 10501, springs 10502 are fixedly disposed on the inner walls of the upper and lower sides of the two air chambers 10501, and a piston 10503 is fixedly disposed on the other end of the springs 10502, the piston 10503 is slidably sleeved inside the air chambers 10501;

[0027] An anti-collision structure 103 is fixedly installed on the outside of the support layer 102. The anti-collision structure 103 includes multiple anti-collision tubes 10302. The multiple anti-collision tubes 10302 are evenly divided into upper and lower groups. A connecting tube 10301 is fixedly sleeved near the buffer structure 105. An air guide tube 10303 is fixedly sleeved on the side of the connecting tube 10301 near the support layer 102. The other end of the air guide tube 10303 passes through the support layer 102 and leads to the interior of the air chamber 10501. One end of the air guide tube 10303 leading to the interior of the air chamber 10501 is located between the two pistons 10503.

[0028] The outer side of the anti-collision structure 103 is provided with a shell 104, and the shell 104 is fixedly connected to the anti-collision tube 10302;

[0029] Specifically, the inner drum 101 is made of oil-resistant and corrosion-resistant polymer plastic, while the outer shell 104 is made of tough polymer material. The outer shell 104 protects the interior of the plastic packaging drum from damage. The anti-collision tubes 10302 help to mitigate impacts on the inner drum 101 and support the outer shell 104. The connecting pipe 10301 facilitates the collection of gas from the multiple anti-collision tubes 10302. The air guide pipe 10303 facilitates gas flow between the air chamber 10501 and the anti-collision tubes 10302. The piston 10503 and spring 10502 facilitate the flow of gas from the anti-collision tubes 10302. 02 The gas entering the air chamber 10501 is returned to the anti-collision tube 10302. The inner walls of the fixed spring 10502 in the air chamber 10501 are provided with air passages so that the piston 10503 can move normally. By setting the plugging rings between the outer shell 104 and the support layer 102 on the upper and lower sides of the anti-collision structure 103 to prevent foreign objects from entering and affecting the anti-collision effect, the three form an anti-collision chamber. The air holes opened in the plugging rings can balance the air pressure in the anti-collision chamber and prevent the gas inside the anti-collision chamber from entering the air chamber 10501 through the air passages after the plastic packaging barrel is squeezed, thus affecting the movement of the piston 10503 and thus affecting the buffering effect.

[0030] Reference Figure 4-6 The upper end of the barrel body 1 is threaded with a slow-flow cover 2. The slow-flow cover 2 includes a barrel cover 201. A slow-flow cavity 204 is opened inside the barrel cover 201. A fixed shaft 205 is fixedly installed between the inner walls on both sides of the slow-flow cavity 204. A fan wheel 206 is rotatably installed on the shaft of the fixed shaft 205.

[0031] Specifically, by setting up the fan wheel 206, the liquid enters the slow-flow chamber 204 and drives the fan wheel 206 to rotate, thereby slowing down the flow rate of the liquid.

[0032] Reference Figure 5The lower end of the bucket lid 201 is provided with a funnel groove 202, the bottom of the funnel groove 202 is provided with a flow groove 203, the flow groove 203 is connected to the slow flow chamber 204, the upper end of the bucket lid 201 is fixedly sleeved with a liquid outlet pipe 207, the liquid outlet pipe 207 is connected to the slow flow chamber 204, and the upper end of the liquid outlet pipe 207 is threaded with a sealing cap 208.

[0033] Specifically, by setting the funnel groove 202, the liquid can flow out of the inner barrel 101 completely when poured. By setting the flow channel 203, the flow rate of the liquid is reduced when it flows through the right-angle corner of the flow channel 203. By setting the sealing cover 208, the liquid is prevented from spilling.

[0034] Reference Figure 5-6 A handle 3 is fixedly installed at the center of the upper end of the bucket lid 201, and a support ring 4 is fixedly installed at the upper edge of the bucket lid 201. A notch 5 is opened on the support ring 4 near the sealing cover 208. The upper surface of the support ring 4 is flush with the upper surface of the handle 3 and the upper surface of the sealing cover 208.

[0035] Specifically, the handle 3 facilitates the rotation and unscrewing of the lid 201, the support ring 4 makes the plastic packaging buckets more stable when stacked, and the notch 5 prevents the support ring 4 from obstructing the pouring of liquid.

[0036] Working principle: When the plastic packaging barrel is impacted or squeezed, the stress point of the outer shell 104 will squeeze the anti-collision tube 10302. When the anti-collision tube 10302 is squeezed, the internal air will enter the air chamber 10501 through the connecting pipe 10301 and the air guide pipe 10303 and push the piston 10503 to move to both sides. At this time, the piston 10503 squeezes the spring 10502. When the external force disappears, the spring 10502 pushes the piston 10503 to discharge the gas back into the anti-collision tube 10302. Thus, the anti-collision tube 10302 supports the outer shell 104 and restores its original shape.

[0037] Secondly, when pouring liquid, the liquid enters the flow channel 203 through the funnel trough 202. When the liquid passes through the right-angle corner of the flow channel 203, it will slow down and enter the slow flow chamber 204. When the liquid flows in the slow flow chamber 204 and is driven to rotate the fan wheel 206, its speed will decrease again. Finally, the liquid that has been slowed down twice will flow out from the liquid outlet pipe 207.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
