Description

Technical Field

[0001] The utility model belongs to the technical field of resin processing, in particular to a raw material feeding structure for resin processing. Background Art

[0002] Resin usually refers to an organic polymer that softens or melts after being heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic products is called a resin. According to the source, it can be divided into natural resin and synthetic resin; according to the different characteristics of its processing behavior, it can be divided into thermoplastic resin and thermosetting resin. It can be used in water treatment, chemical industry, pharmaceutical industry, coatings and adhesives, packaging and construction. In the process of resin production and processing, the raw materials of resin often need to be heated and melted for subsequent processing, but the viscosity of hot-melt raw materials is high and it is not convenient to feed. Therefore, a feeding structure is set to feed the hot-melt raw materials to improve production efficiency, but it still has the following disadvantages in actual use:

[0003] 1. The utility model with publication number CN220390037U discloses a resin processing feeding device, wherein a first motor is installed on the upper end surface of the mixing drum, the output end of the first motor penetrates the upper end surface of the mixing drum and is installed with a stirring rod, and two scrapers distributed on the left and right and slidably connected to the inner wall of the mixing drum are installed at the bottom of the outer wall of the stirring rod, and a support plate is arranged on the right side of the mixing drum. The resin processing feeding device usually stirs and mixes the resin raw material in the mixing drum, and makes the resin hot-melted for the next processing. However, in actual operation, due to the high viscosity of the hot-melt resin raw material, the resin is directly hot-melted in the mixing drum, and the inner wall of the mixing drum and the surface of the stirring rod will adhere to the residual resin, and there will also be a large amount of resin residue in the feeding drum, and due to the presence of the stirring rod and the spiral rod, the cleaning dead angle in the device will be greatly increased, which is not convenient for cleaning in a simple way, and the cleaning difficulty of the staff is increased;

[0004] 2. In the process of feeding the hot-melt resin raw material, since the resin raw material will condense after returning to room temperature, it is necessary to use up all the resin raw materials in the feeding structure at one time to avoid the resin remaining in the structure solidifying and the screw rod being unable to rotate when it is used again. However, in the actual production process, it is inevitable that there are unexpected situations that require the raw materials to be retained in the feeding structure. In order to avoid clogging of the structure, the raw materials can only be poured out and heated and melted again during the next production, which is a cumbersome operation. Utility Model Content

[0005] The utility model aims to provide a raw material feeding structure for resin processing. Through a mixing barrel, a conveying pipe and an air pump, the utility model solves the problem that in actual use, after the raw material conveying is completed, a certain amount of resin will remain in the mixing barrel and the feeding barrel, and there are many cleaning dead corners in the structure, which is not convenient for cleaning. In order to avoid the raw materials condensing on the inner side of the structure and causing the device to malfunction during the feeding process, the remaining raw materials are usually poured out and all hot-melted again during the next processing, which is a cumbersome operation.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a raw material feeding structure for resin processing, comprising a mixing barrel, a conveying pipe and an air pump, wherein a second discharging hopper is fixedly connected in the mixing barrel, a stirring motor is arranged on the top of the mixing barrel, a conveying pipe is arranged at the bottom of the mixing barrel, a heating pipe is fixedly connected inside the conveying pipe, an air pump is arranged at one end of the conveying pipe, a slow flow pipe is penetrated and connected at the bottom of the air pump, and a vent pipe is penetrated and connected at the outer peripheral surface of the air pump;

[0008] When the raw materials are mixed and stirred, the stirring motor drives the stirring rod to rotate and stir the raw materials. When the mixture is uniform, the second discharge hopper can be opened to allow the mixed raw materials to fall to the bottom of the mixing barrel for storage, which is convenient for use at any time. A new portion of raw materials can be poured into the upper side of the second discharge hopper for stirring and mixing, thereby improving production efficiency. The mixed raw materials fall to the inside of the conveying pipe under the action of gravity and air flow, and move along the conveying pipe with the flow of air. The conveying pipe is heated by the heating pipe to further heat the raw materials, so that the raw materials are gradually melted during the conveying process. There is no need to melt the raw materials in the mixing barrel, thereby avoiding the problem of cooling the raw materials during the conveying process. When cleaning, only the inside of the conveying pipe needs to be cleaned, and there are fewer dead corners in the conveying pipe, which greatly reduces the difficulty of cleaning. The air flow driven by the air pump can increase the moving speed of the raw materials in the conveying pipe and improve the conveying efficiency. When the raw materials are not needed, the feeding structure can stop running at any time, so that the raw materials are retained in the structure. When processing is needed again, the heating pipe is opened again to heat the raw materials, thereby improving the convenience of use.

[0009] Furthermore, a top cover is fixedly connected to the top of the mixing barrel, a feed hopper is welded through the top of the top cover, the stirring motor is fixedly connected to the top of the top cover, a stirring rod is rotatably connected to the bottom of the stirring motor, stirring blades are fixedly connected to the outer peripheral surface of the stirring rod, and the stirring rod is suspended from the top of the second discharge hopper;

[0010] The stirring motor can drive the stirring blade to rotate, and further stir the raw materials in the mixing barrel. After the raw materials are evenly stirred, the second discharge hopper can be opened to allow the raw materials to fall to the bottom of the mixing barrel for storage and further feeding processing, and a new portion of multiple raw materials can be poured into the second discharge hopper again, and mixed again by the rotation of the stirring blade, thereby improving production efficiency.

[0011] Furthermore, a first discharging hopper is welded through the bottom of the mixing barrel, a feeding pipe is clamped through the bottom of the first discharging hopper, and a support frame is clamped and fixed around the bottom of the first discharging hopper;

[0012] By opening the first discharging hopper, the evenly mixed raw materials at the bottom of the mixing barrel can be discharged and fall into the conveying pipe for heating and conveying. The raw materials do not need to be heated in the mixing barrel, which avoids residual raw materials from adhering to the mixing barrel and reduces the cleaning difficulty for the staff.

[0013] Furthermore, a first one-way valve is inserted through one end of the outer circumference of the delivery pipe, a connecting pipe is inserted through the top of the outer circumference of the delivery pipe, and a water inlet pipe and an air inlet pipe are inserted through one end of the outer circumference of the delivery pipe. The first one-way valve is located between the air inlet pipe and the water inlet pipe, and the water inlet pipe is located between the connecting pipe and the first one-way valve. The connecting pipe is fixed to the bottom of the feeding pipe;

[0014] The first one-way valve can prevent the fallen raw materials from falling into the inner side of the ventilation pipe, and prevent the cleaning liquid from entering the inner side of the ventilation pipe when cleaning the conveying pipe, thereby preventing the ventilation pipe from being blocked. The raw materials that fall into the conveying pipe can be heated by the heating pipe, so that the raw materials can be hot-melted while being conveyed, thus avoiding the problem of cooling the raw materials during the conveying process. Moreover, when cleaning, only the inside of the conveying pipe needs to be cleaned, and there are fewer cleaning dead corners in the conveying pipe, thereby greatly reducing the difficulty of cleaning.

[0015] Furthermore, a partition net is fixedly connected inside the delivery pipe, one end of the delivery pipe penetrates and is connected to the outer peripheral surface of the slow flow pipe, the slow flow pipe is located at the other end of the delivery pipe relative to the air intake pipe, the mixing barrel is located between the slow flow pipe and the air intake pipe, and the ventilation pipe penetrates and is connected to one end of the air intake pipe;

[0016] The partition net can prevent the raw materials from entering the slow-flow tube and being discharged before they are hot-melted. When the raw materials are not needed, the feeding structure can stop running at any time, so that the raw materials are retained in the structure. When processing is needed again, the heating tube can be turned on again to heat the raw materials, thereby improving the convenience of use.

[0017] Furthermore, a second one-way valve is inserted through the bottom of the slow-flow pipe and connected thereto, a discharge pipe is inserted through the bottom of the second one-way valve and connected thereto, and the delivery pipe is located between the second one-way valve and the air pump;

[0018] The air in the conveying pipe is evacuated by an air pump, so that the raw materials move along the conveying pipe with the flow of air, thereby improving the conveying efficiency of the raw materials. The hot air can circulate through the ventilation pipe to avoid a large amount of heat loss, and the movement of the raw materials is driven by the airflow, which can simplify the structure of the conveying pipe and reduce costs.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model solves the problem that the resin processing feeding device usually stirs and mixes the resin raw materials in the mixing drum and melts the resin for the next step of processing by arranging a mixing barrel, a conveying pipe and an air pump. However, in actual operation, due to the high viscosity of the hot-melt resin raw materials, the resin is directly melted in the mixing barrel, and the inner wall of the mixing barrel and the surface of the stirring rod will adhere to the residual resin, and there will also be a large amount of resin residue in the feeding barrel. In addition, due to the presence of the stirring rod and the spiral rod, the cleaning dead angle in the device will be greatly increased, which is not convenient for cleaning in a simple way and increases the cleaning difficulty of the staff. After the raw materials are mixed evenly in the mixing barrel, they fall to the bottom of the mixing barrel, and another portion of raw materials is put into the second discharging hopper for mixing and stirring. The evenly mixed raw materials fall to the inside of the conveying pipe under the action of gravity and air flow. The air is circulated by the air pump, so that the raw materials are quickly moved along the conveying pipe with the air, thereby improving the conveying efficiency of the raw materials in the conveying pipe. After use, only the inside of the conveying pipe needs to be cleaned, and the movement of the raw materials is driven by the airflow, thereby greatly reducing the cleaning dead angle in the feeding structure and reducing the cleaning difficulty.

[0021] 2. The utility model solves the problem that in the process of feeding the hot-melt resin raw material, since the resin raw material will condense after returning to normal temperature, it is necessary to use up all the resin raw materials in the feeding structure at one time to avoid the resin remaining in the structure from solidifying and the spiral rod being unable to rotate when it is used again. However, in the actual production process, it is inevitable that there are unexpected situations where the raw materials need to be retained in the feeding structure. To avoid clogging of the structure, the raw materials can only be poured out and heated and melted again during the next production, which is a relatively cumbersome operation. The delivery pipe is heated by the heating pipe, and the raw materials passing through the delivery pipe are further heated to make the raw materials melt in the delivery pipe. When the raw materials are not needed, the feeding structure can be directly shut down, and the heating pipe can be started when it is needed again to melt the condensed raw materials in the delivery pipe. The operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

When the stirring of one portion of the raw materials is completed, the second discharge hopper 107 is opened to allow the raw materials to fall to the bottom of the mixing barrel 1, and fall to the inside of the conveying pipe 2 under the action of gravity. The air pump 3 evacuates the conveying pipe 2, allowing the air to enter the inside of the ventilation pipe 302 and then flow back into the conveying pipe 2, pushing the raw materials in the conveying pipe 2. When the raw materials move along the conveying pipe 2 with the air, the conveying pipe 2 is heated by the heating pipe 206. The raw material is further heated to melt the raw material. The raw material melted to liquid state falls to the inside of the slow flow tube 301 and is discharged under the action of gravity. When the raw material is not needed, the feeding structure is directly closed to allow the melted raw material to condense in the delivery tube 2. When it is needed again, the feeding structure is opened and the delivery tube 2 is heated again by the heating tube 206 to melt the raw material. When the feeding structure needs to be cleaned, water is pumped into the delivery tube 2 through the water inlet pipe 202. The water is heated in the delivery tube 2 and takes away the raw material remaining in the delivery tube 2.

[0033] Pour a portion of mixed raw materials into the feed hopper 103, and the raw materials fall into the mixing barrel 1 under the action of gravity. The stirring motor 101 drives the stirring rod 108 and the stirring blade 109 to rotate, and further stirs the raw materials in the mixing barrel 1. After the raw materials are evenly stirred, open the second discharge hopper 107 to allow the raw materials to fall to the upper side of the first discharge hopper 104, close the second discharge hopper 107 and pour another portion of mixed raw materials into the mixing barrel 1 through the feed hopper 103. When the resin raw material is needed, open the discharge pipe 105 to allow the raw materials to fall into the conveying pipe 2 for conveying under the action of gravity.

[0035] After the raw materials fall into the conveying pipe 2, the raw materials move along the conveying pipe 2 with the direction of the air flow, and the raw materials falling into the conveying pipe 2 are heated by the heating pipe 206, so that the raw materials are heat-melted while being conveyed. The raw materials that have not yet been heat-melted are blocked on one side of the partition net 205 when moving to the partition net 205, so as to avoid direct discharge of solid raw materials. When the feeding structure needs to be cleaned after use, the water inlet pipe 202 is opened to allow clean water to enter the conveying pipe 2, and the conveying pipe 2 is flushed with clean water to quickly clean the inside of the conveying pipe 2.
