Description

Technical Field

[0001] The invention relates to the field of sheet material production, and in particular to an oven device used in a sheet material production line and a control method thereof. Background Art

[0002] Sheet production generally refers to the process of converting raw materials into sheet materials through different processing methods during industrial manufacturing. This production method is widely used in many industries, including but not limited to plastics, metals, paper, composite materials, polymer materials, etc.

[0003] Certain polymer materials or additives (such as nylon, polycarbonate) have high hygroscopicity and easily absorb moisture from the air. Such materials almost always need to be dried before processing to reduce the moisture content and avoid processing defects and product quality problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an oven device for a sheet production line and a control method thereof.

[0005] In a first aspect, the present invention provides an oven device for a sheet production line, comprising a cylinder, the top of the cylinder is fixedly connected to a feed hopper, the bottom of the cylinder is fixedly connected to a lower hopper, and further comprising:

[0006] A crushing assembly installed inside the feed hopper;

[0007] A rotary drying assembly is installed inside the cylinder, and the rotary drying assembly arranges the raw materials in equal intervals through the interval spaces arranged in a circumferential array. The rotary drying assembly also includes an air flow conveying assembly, which conveys air flow to one of the interval spaces, and the air flow is discharged from the air flow conveying assembly after passing through each interval space in turn;

[0008] A guide hopper is fixed inside the cylinder and located above the rotary drying assembly, and is used to guide the raw materials dropped from the feed hopper into the rotary drying assembly for rotary drying;

[0009] A material feeding amount control component is installed inside the cylinder and below the guide bucket, and is used to control the amount of the raw materials dropped from the feed hopper to control the amount of the raw materials entering the guide bucket;

[0010] The raw material enters the interior of the cylinder from the feed hopper and then passes through the material discharge quantity control component, which controls the feed amount of the raw material. After passing through the material discharge quantity control component, the raw material reaches the guide bucket and enters the rotary drying component under the guidance of the guide bucket. The raw material enters one of the interval spaces in the rotary drying component. As the rotary drying component rotates, the interval spaces are driven to rotate, so that the raw material enters the interior of each interval space in turn. Under the control of the material discharge quantity control component on the feed amount, the amount of raw material entering each interval space is the same, which is conducive to the same amount of raw material being dried in each interval space, and the airflow conveying component can transport The air supply flows to the inside of one of the interval spaces, so that the dry low-temperature airflow rotates one circle along the trajectory of the interval space, which is beneficial to drying the raw materials inside each interval space through the airflow. The flow direction of the airflow is opposite to the rotation direction of the interval space, so that the initial dry airflow dries the driest raw material, which is beneficial to improve the drying effect of the raw material. The raw material rotates one circle with the rotation of the interval space and is discharged. The raw material is discharged from the lower hopper to complete the drying of the raw material, which is beneficial to low-temperature drying of the raw material, thereby helping to avoid processing defects and product quality caused by excessive moisture content in the raw material.

[0011] Preferably, the rotary drying assembly comprises:

[0012] A rotating shaft is rotatably mounted inside the cylinder and driven to rotate by a driving assembly;

[0013] A plurality of partitions are fixed on the outer wall of the rotating shaft in a circumferential array, the partition space is generated by the partitions, the top of the partition space matches the bottom opening of the guide bucket, the bottom of the cylinder is provided with a discharge port connected to the discharge hopper, the bottom of the partition space matches the discharge port, and the interior of the partition is provided with an inner groove;

[0014] An air inlet is arranged one-to-one with the partitions and is opened on one side of the corresponding partition;

[0015] The air outlet is arranged one by one corresponding to the partitions and is opened on the other side of the corresponding partition;

[0016] One-way ventilation components are arranged one by one in correspondence with the partition spaces and are installed at the bottom of the corresponding partition spaces so that air flows along the air outlet through the one-way ventilation components and enters the partition spaces in one direction;

[0017] A material unloading mechanism, installed inside the partition space, for unloading and conveying the raw materials inside the partition space;

[0018] After the driving assembly is started, the rotating shaft is driven to rotate, and after the rotating shaft rotates, the partition is driven to rotate, thereby driving the interval space formed by the partition to rotate. When the interval space is aligned with the bottom opening of the guide bucket, the raw material falls from the inside of the guide bucket to the inside of the interval space, and then with the rotation of the interval space, the raw material is driven to rotate until the interval space rotates to the bottom and is aligned with the discharge opening opened at the bottom of the cylinder. At this time, the discharge mechanism is started, so that the raw material falls from the inside of the interval space to the discharge hopper and is discharged, thereby forming a rotation transfer of the raw material;

[0019] After the airflow conveying component conveys airflow to the interior of one of the partition spaces, the air pressure inside the partition space increases, and the airflow enters the interior of the partition along the air inlet of the partition, and is then discharged from the air outlet of the partition, so that the airflow flows in sequence between the partition spaces until the airflow flows to the partition space connected to the exhaust pipe, and then the airflow is discharged along the exhaust pipe, thereby realizing the flow of airflow inside the partition space. Taking one of the partition spaces as an example, it is regarded as the initial partition space. After the raw material enters the initial partition space, as the initial partition space rotates, it first rotates to the position connected to the exhaust pipe, so that the humidity of the airflow flowing through the raw material is the highest, and then as the initial partition space rotates, the humidity of the airflow As the initial interval space rotates, the humidity of the air flow passing through the raw materials gradually decreases, until the final initial interval space rotates to a position connected to the air pump, so that the dry air flow input by the air pump passes through the initial interval space, so that during the rotation of the raw materials driven by the initial interval space, the air flow passing through the raw materials gradually becomes dry, thereby achieving drying treatment of the raw materials, thereby rotating the direction of the air flow and the raw materials, which is beneficial to improving the drying effect of the raw materials, and through the dispersed treatment of the raw materials, real-time drying and dispersed drying of the raw materials are achieved, which is beneficial to improving the drying effect of the raw materials, and the dried raw materials immediately enter the production line, which is beneficial to avoiding the situation where the raw materials are damp again during the storage process after drying.

[0020] Preferably, the one-way ventilation assembly comprises:

[0021] A fixed box, located at the bottom of the partition space, with one side fixedly connected to the side of the partition, so that the fixed box is connected to the air outlet through one side;

[0022] An inclined surface is arranged on the top of the fixed box;

[0023] One-way valves are divided into two groups, and the two groups of one-way valves are fixed inside the fixed box in a linear array, and the one-way valves penetrate the inclined surface on the top of the fixed box, and the airflow enters the interval space from the inside of the fixed box through the one-way valves in one direction;

[0024] The airflow enters the interior of the fixed box along the air outlet, and the fixed box is connected with all the one-way valves, so that the airflow can be ejected along each one-way valve after having a certain air pressure. An inclined surface is arranged on the top of the fixed box. Due to the setting of the inclined surface, the top of the fixed box presents a depression, and the raw materials are accumulated inside the depression, and one end of the one-way valve is located on the inclined surface, so that when the airflow is ejected from the one-way valve, the airflow is ejected along the inclined surface, so that the ejected airflow is ejected obliquely from the bottom of the accumulated raw materials, which is conducive to the airflow fully contacting with the raw materials when ejected, and the raw materials can be pushed to turn over by the ejection of the airflow to the left and right, which is conducive to the full drying of the raw materials.

[0025] Preferably, the unloading mechanism comprises:

[0026] A lifting box, wherein the middle part of the fixed box is a hollow through slot, the lifting box is clamped in the middle part of the fixed box, and the side wall of the lifting box abuts against the inner wall of the hollow through slot of the fixed box;

[0027] A cylinder fixed to the side wall of the partition;

[0028] A lifting block is fixed to the bottom of the telescopic rod of the cylinder, the lifting block is vertically slidably inserted into the bottom of the fixed box, and the lifting block is fixedly connected to the lifting box;

[0029] After the cylinder is started, the lifting block is driven to move through the telescopic rod, and the lifting block drives the lifting box to move vertically. When the side wall of the lifting box is against the inner wall of the hollow groove of the fixed box, the raw materials are accumulated in the depression formed by the top of the lifting box and the inclined surface of the fixed box. When the lifting box moves downward, the side wall of the lifting box is separated from the inner wall of the hollow groove of the fixed box, so that a gap is formed between the two. At this time, the raw materials can fall from the gap between the two, thereby realizing the unloading of the raw materials.

[0034] When the raw materials are accumulated on the top of the lifting box, the debris in the raw materials falls along the filter screen to the inside of the lifting box, so that the debris in the raw materials can be separated, which is beneficial to avoid the debris in the raw materials from accumulating at the one-way valve outlet under the impact of the airflow and causing blockage. After the debris enters the interior of the lifting box, when the lifting box moves downward, the discharge port on the side wall of the lifting box is exposed, and a solenoid valve is installed inside the discharge port. When the debris in the raw materials is the fragments dropped from the raw materials, the solenoid valve is controlled to open. At this time, after the discharge port is exposed, the debris falls under the guidance of the guide slope, and thus falls together with the raw materials and is discharged through the lower hopper. When the debris in the raw materials is impurities mixed in during the storage and transportation of the raw materials, the solenoid valve is controlled to close. At this time, after the discharge port is exposed, the debris is still stored in the interior of the lifting box until the raw materials are processed. The solenoid valve is opened so that the debris is discharged from the discharge port for cleaning when the lifting box moves downward, which is beneficial to control the collection of the debris or discharge with the raw materials according to the nature of the debris in the raw materials, which is beneficial to avoid causing processing defects and affecting product quality.

[0038] When the airflow flows through the raw materials, as the equipment works, there is a situation where the equipment generates heat. When the temperature of the equipment rises, the temperature of the airflow gradually rises. After the temperature of the airflow rises, there is a situation where the raw materials are unstable. When the airflow flows through the heat conduction plate, because the opening at the top of the trumpet-shaped groove is large and the opening at the bottom is small, when the airflow flows through the trumpet-shaped groove from top to bottom, the temperature of the airflow decreases, which helps to alleviate the situation of airflow heating.

[0039] Preferably, it also includes:

[0040] A cooling cylinder is fixed inside the rotating shaft, a connecting block is fixed on the side wall of the heat conducting plate, and the connecting block penetrates the partition plate and is connected to the cooling cylinder;

[0044] The liquid inlet pipe is connected to an external water pump, so that water flows into the liquid inlet along the transfer space, and then the water flows along the cooling pipe to the discharge port, and is discharged from the discharge pipe after passing through the transfer space of the outer circle, thereby realizing water cooling of the cooling pipe. The cooling pipe is connected to the heat conduction plate through a connecting block, thereby realizing cooling of the heat conduction plate, thereby cooling the airflow passing through the inside of the heat conduction plate, which is beneficial to avoid the occurrence of airflow temperature rise.

[0048] The controller sends the material unloading control information to the cylinder to control the corresponding cylinder to start;

[0049] When the spacing space is aligned with the unloading hopper, the first pressure sensor of the cylinder inside the corresponding spacing space is pressurized. When the first pressure sensor is pressurized, pressure information is generated and the pressure information is sent to the controller.

DETAILED DESCRIPTION

[0077] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0078] like Figures 2 to 12 The oven device for a sheet production line shown in the figure comprises a cylinder 1, the top of the cylinder 1 is fixedly connected to a feed hopper 2, the bottom of the cylinder 1 is fixedly connected to a lower hopper 19, and further comprises:

[0079] A crushing assembly is installed inside the feed hopper 2;

[0080] The rotary drying assembly is installed inside the cylinder 1. The rotary drying assembly arranges the raw materials in equal intervals through the interval spaces arranged in a circumferential array. The rotary drying assembly also includes an air flow conveying assembly. The air flow conveying assembly conveys air flow to one of the interval spaces. The air flow passes through each interval space in turn and is discharged by the air flow conveying assembly.

[0081] The guide hopper 6 is fixed inside the cylinder 1 and located above the rotary drying assembly, and is used to guide the raw materials dropped from the feed hopper 2 into the rotary drying assembly for rotary drying;

[0082] The material feeding control assembly is installed inside the cylinder 1 and below the guide bucket 6, and is used to control the amount of the raw materials dropped from the feed hopper 2, so as to control the amount of the raw materials entering the guide bucket 6;

[0083] Some polymer materials or additives such as nylon and polycarbonate have high hygroscopicity and easily absorb moisture from the air. Such materials almost always need to be dried before processing to reduce the moisture content and avoid processing defects and product quality problems.

[0084] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the raw material enters the interior of the cylinder 1 from the feed hopper 2, and then passes through the material discharge quantity control component. The material discharge quantity control component controls the feed amount of the raw material. After passing through the material discharge quantity control component, the raw material reaches the guide bucket 6, and enters the rotary drying component under the guidance of the guide bucket 6. The raw material enters one of the interval spaces in the rotary drying component. As the rotary drying component rotates, the interval space is driven to rotate, so that the raw material enters the interior of each interval space in turn. Under the control of the material discharge quantity control component on the feed amount, the amount of raw material entering each interval space is the same, which is conducive to the same amount of raw material in each interval space. The airflow conveying component can convey the airflow to the inside of one of the partition spaces, so that the dry low-temperature airflow rotates one circle along the trajectory of the partition space, which is beneficial to drying the raw materials inside each partition space through the airflow, and the flow direction of the airflow is opposite to the rotation direction of the partition space, so that the initial dry airflow dries the driest raw material, which is beneficial to improve the drying effect of the raw material. The raw material rotates one circle with the rotation of the partition space and is discharged, and is discharged from the lower hopper 19 to complete the drying of the raw material, which is beneficial to low-temperature drying of the raw material, thereby helping to avoid processing defects and product quality caused by excessive moisture content in the raw material.

[0085] As an optional embodiment, the air flow conveying component includes:

[0086] The air pump 15 is fixed on the outer wall of the cylinder 1, and the output end of the air pump 15 is connected to one of the compartments inside the cylinder 1;

[0087] The exhaust pipe 16 is fixed on the outer wall of the cylinder 1 and communicates with one of the compartments inside the cylinder 1;

[0088] The output end of the air pump 15 and the exhaust pipe 16 are respectively located on both sides of the bottom opening of the guide bucket 6;

[0089] A desiccant 17 is fixed inside the exhaust pipe 16;

[0090] After the air pump 15 is started, the conveying air flow flows to one of the interval spaces. After the air flow enters the interior of the interval space, it flows along the interval spaces in sequence until the air flow flows to the interior of the interval space connected to the exhaust pipe 16. The air flow is then discharged from the exhaust pipe 16, thereby forming a flow trajectory of the air flow. During the process of being discharged from the exhaust pipe 16, the air flow is dried by the desiccant 17, so that the external moisture will not enter the interior of the interval space through the exhaust pipe 16 and cause the raw materials to become damp again.

[0091] As an optional embodiment, the material feeding quantity control component includes:

[0092] The rotating transfer plate 5 is rotatably mounted inside the cylinder 1 through the top and bottom partitions;

[0093] The spacing openings 501 are formed in a circular array and are opened through the top of the rotating transfer plate 5;

[0094] A second motor 506 is fixed to the top of the cylinder 1, and a third gear 505 is fixed to the output shaft of the second motor 506;

[0095] The second gear 504 is rotatably mounted on the top of the cylinder 1. The rotating shaft of the second gear 504 passes through the top of the cylinder 1 and is coaxially fixedly connected with the top of the rotating transfer plate 5.

[0096] The first opening 502 is formed through the top partition of the rotating transfer plate 5 and communicates with the bottom of the feed hopper 2 and the partition opening 501;

[0097] The second opening 503 is formed through the bottom partition of the rotating transfer plate 5 and connects the guide hopper 6 with the partition opening 501;

[0098] After the second motor 506 is started, it drives the third gear 505 connected to it to rotate through the output shaft, and the third gear 505 drives the second gear 504 meshing with it to rotate, and the second gear 504 drives the rotating transfer plate 5 to rotate, and the rotating transfer plate 5 drives the spacing opening 501 to rotate. When the spacing opening 501 rotates to align with the first opening 502, the raw materials in the feed hopper 2 can enter the interior of the spacing opening 501 through the first opening 502, and when the spacing opening 501 rotates to align with the second opening 503, the raw materials can enter the interior of the guide bucket 6 through the second opening 503, thereby driving the raw materials to pass through the rotating transfer plate 5. By controlling the rotation speed of the rotating transfer plate 5, the conveying speed of the raw materials can be controlled, which is beneficial to controlling the conveying amount of the raw materials, and is beneficial to avoiding excessive loading of raw materials, resulting in excessive amount of raw materials accumulated inside the spacing space, thereby affecting the efficiency of the airflow passing through the raw materials to dry the raw materials.

[0099] As an optional embodiment, the crushing assembly includes:

[0100] Two crushing rollers 3 are rotatably mounted inside the feed hopper 2. The rotating shafts of the two crushing rollers 3 penetrate the side wall of the feed hopper 2 and are fixed with first gears 302. The two first gears 302 are meshed with each other.

[0101] The screen 4 is fixed inside the feed hopper 2 and is located below the two crushing rollers 3;

[0102] The first motor 301 is fixed on the side wall of the feed hopper 2, and the output shaft of the first motor 301 drives one of the first gears 302 to rotate;

[0103] After the first motor 301 is started, the output shaft drives the first gear 302 connected thereto to rotate, and the first gear 302 drives another first gear 302 meshing therewith to rotate, thereby driving the two crushing rollers 3 to rotate through the two first gears 302. When the raw materials fall from the feed hopper 2, small particles of the raw materials pass through the screen 4 and fall, while large particles of the raw materials are intercepted by the screen 4. When the intercepted raw materials reach a certain amount, the first motor 301 is started, thereby driving the crushing rollers 3 to rotate and crush the raw materials, which is conducive to allowing the raw materials to enter the interior of the rotary drying component for drying after crushing, thereby helping to avoid the situation where the drying efficiency is different due to the raw materials being too large, thereby causing some raw materials to be not dried thoroughly, thereby helping to avoid processing defects and product quality problems.

[0104] As an optional embodiment, the rotary drying component includes:

[0105] The rotating shaft 703 is rotatably mounted inside the cylinder 1 and driven to rotate by the driving assembly;

[0106] A plurality of partitions 7 are fixed on the outer wall of the rotating shaft 703 in a circumferential array, and the partition space is generated by the partitions 7. The top of the partition space matches the bottom opening of the guide bucket 6. A discharge port connected to the discharge hopper 19 is provided at the bottom of the cylinder 1. The bottom of the partition space matches the discharge port. The partitions 7 are all provided with inner grooves.

[0107] The air inlet 701 is arranged in one-to-one correspondence with the partition 7 and is opened on one side of the corresponding partition 7;

[0108] The air outlet 702 is arranged one by one corresponding to the partition 7 and is opened on the other side of the corresponding partition 7;

[0109] One-way ventilation components are arranged one by one in correspondence with the partitions and installed at the bottom of the corresponding partitions, so that air flows along the air outlet 702 through the one-way ventilation components and enters the partitions in one direction;

[0110] A material unloading mechanism is installed inside the partition space and is used for unloading and conveying the raw materials inside the partition space;

[0111] After the driving assembly is started, the rotating shaft 703 is driven to rotate. After the rotating shaft 703 rotates, the partition plate 7 is driven to rotate, thereby driving the partition space formed by the partition plate 7 to rotate. When the partition space is aligned with the bottom opening of the guide bucket 6, the raw material falls from the inside of the guide bucket 6 to the inside of the partition space. Then, as the partition space rotates, the raw material is driven to rotate until the partition space rotates to the bottom and is aligned with the discharge opening opened at the bottom of the cylinder 1. At this time, the discharge mechanism is started, so that the raw material falls from the inside of the partition space to the discharge hopper 19 and is discharged, thereby forming a rotary transfer of the raw material;

[0112] After the airflow conveying component conveys air to the interior of one of the partition spaces, the air pressure inside the partition space increases, and the airflow enters the interior of the partition 7 along the air inlet 701 of the partition 7, and is then discharged from the air outlet 702 of the partition 7, so that the airflow flows in sequence between the partition spaces until the airflow flows to the partition space connected to the exhaust pipe 16, and then the airflow is discharged along the exhaust pipe 16, thereby realizing the flow of airflow inside the partition space. Taking one of the partition spaces as an example, it is regarded as the initial partition space. After the raw material enters the initial partition space, as the initial partition space rotates, it first rotates to the position connected to the exhaust pipe 16, so that the humidity of the airflow flowing through the raw material is the highest, and then as As the initial interval space rotates, the humidity of the air flow passing through the raw materials gradually decreases until the initial interval space finally rotates to a position connected to the air pump 15, so that the dry air flow input by the air pump 15 passes through the initial interval space, and the air flow passing through the raw materials gradually becomes dry during the rotation of the raw materials by the initial interval space, thereby achieving drying of the raw materials. The rotation of the air flow and the direction of the raw materials is beneficial to improving the drying effect of the raw materials, and through the dispersed processing of the raw materials, real-time drying and dispersed drying of the raw materials are achieved, which is beneficial to improving the drying effect of the raw materials.
