Description

Technical Field

[0001] This utility model relates to the field of polyester resin production technology, and more specifically, to a reaction vessel injection device for the production of unsaturated polyester resin. Background Technology

[0002] The vacuum feeding device for the reactor used in the production of unsaturated polyester resin is a sample feeding system that achieves automatic material conveying through negative pressure suction. It mainly consists of a vacuum pump, a sealed silo, a filter, a conveying pipeline, and a control system. Its working principle is to use vacuum negative pressure to suck powder or liquid raw materials from the storage tank into the reactor. It has the advantages of high efficiency, airtightness, pollution prevention, and reduced dust spillage. It is suitable for flammable and explosive or high cleanliness production environments.

[0003] The existing unsaturated polyester resin production reactor feeding device lacks a hopper-vibration structure, which causes powder or viscous materials to easily adhere to the inner wall of the hopper and accumulate. This adhesion phenomenon can lead to incomplete material conveying, affect the accuracy of the proportioning, and even cause pipeline blockage in severe cases. The material residue problem is more prominent when dealing with high-viscosity raw materials or in humid environments, which not only reduces production efficiency but also increases the workload of subsequent cleaning and maintenance.

[0004] In summary, to improve the batching accuracy and conveying efficiency of unsaturated polyester resin production, it is necessary to solve the problem of materials easily adhering to the inner wall of the hopper during vacuum feeding, so that the raw materials can smoothly and thoroughly enter the reactor, thereby ensuring the continuity of the production process and the stability of product quality. Utility Model Content

[0005] The present invention provides a sample feeding device for a reactor used in the production of unsaturated polyester resin, which aims to solve the problem that existing sample feeding devices for reactors used in the production of unsaturated polyester resin lack a structure for striking and vibrating the hopper, causing materials to easily stick to the inner wall of the hopper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reaction vessel feeding device for unsaturated polyester resin production, comprising a hopper, a feeding pipe at the bottom of the hopper, the feeding pipe being connected to an external vacuum feeder pipe, a set of first bearing seats installed on both the left and right sides of the hopper, a first drive shaft connected between each set of first bearing seats, a protrusion fixed to the outer side of the first drive shaft, a first bevel gear installed at the front end of the first drive shaft, a set of second bearing seats fixed to the front side of the hopper, a second drive shaft connected between the second bearing seats, second bevel gears fixed to both the left and right ends of the second drive shaft, the second bevel gears meshing with the corresponding first bevel gears, a transmission mechanism provided on the front side of the hopper for driving the second drive shaft to rotate, and a positioning component provided on the rear side of the hopper.

[0007] In a preferred embodiment, the transmission mechanism includes a support component and a drive component, wherein the support component is used to mount the drive component and the drive component is used to drive the second transmission shaft to rotate.

[0008] In a preferred embodiment, the support assembly includes a fixing plate fixed to the front side of the hopper, and two support rods are installed at the bottom of the fixing plate, the support rods being fixedly connected to the hopper.

[0009] In a preferred embodiment, the drive assembly includes a drive motor mounted on the top of a fixed plate, a drive gear mounted on the output end of the drive motor, and a driven gear mounted on the outer side of the second transmission shaft, with the drive gear meshing with the driven gear.

[0010] In a preferred embodiment, the positioning component includes an adjustment component and a limiting component, wherein the adjustment component is used to adapt to an external fixing bracket, and the limiting component is used to limit the adjustment component.

[0011] In a preferred embodiment, the adjusting assembly includes a mounting frame fixed to the rear side of the hopper, a bidirectional lead screw rotatably connected inside the mounting frame, a knob connected to the right end of the bidirectional lead screw through the mounting frame, the knob being used to drive the bidirectional lead screw to rotate, and two movable seats threadedly connected to the outer side of the bidirectional lead screw.

[0012] In a preferred embodiment, the limiting component includes a limiting frame fixed to the rear side of the hopper, a limiting rod fixed inside the limiting frame, two sliding blocks slidably connected through the outer side of the limiting rod, a connecting rod fixed between the sliding blocks and the corresponding movable seats, and a mounting plate fixed to the rear side of both the sliding blocks and the movable seats.

[0013] The beneficial effects of this utility model are as follows: This invention, by incorporating protrusions, ensures that the hopper experiences continuous and uniform impact vibration during the feeding process. This effectively solves the problem of material easily adhering to the inner wall in traditional vacuum feeding devices. This design significantly improves the flowability of powdered or viscous materials, ensuring that raw materials can fully and thoroughly enter the reactor, avoiding proportioning deviations and batch contamination caused by material residue. At the same time, the automated vibration method reduces the cleaning frequency, thereby improving production efficiency and reducing raw material waste. It is particularly suitable for conveying high-humidity environments or high-viscosity resin raw materials, providing a reliable guarantee for the continuous production of unsaturated polyester resin.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Refer to the instruction manual appendix Figures 1 to 5 A sample feeding device for a reactor used in the production of unsaturated polyester resin includes a hopper 1, a feeding pipe 2 at the bottom of the hopper 1, which is connected to an external vacuum feeder pipe. A set of first bearing seats 3 are installed on both the left and right sides of the hopper 1. A first drive shaft 4 is connected between each set of first bearing seats 3. A protrusion 5 is fixed on the outside of the first drive shaft 4. A first bevel gear 6 is installed at the front end of the first drive shaft 4. A set of second bearing seats 7 is fixed on the front side of the hopper 1. A second drive shaft 8 is connected between the second bearing seats 7. A second bevel gear 9 is fixed at both ends of the second drive shaft 8. The second bevel gear 9 meshes with the corresponding first bevel gear 6. A transmission mechanism is provided on the front side of the hopper 1 to drive the second drive shaft 8 to rotate. A positioning component is provided on the rear side of the hopper 1.

[0022] It should be noted that when the transmission mechanism is in operation, it can drive the second transmission shaft 8 to rotate. The second transmission shaft 8 is rigidly connected to the second bevel gear 9, thereby driving the second bevel gear 9 to rotate synchronously. When the second bevel gear 9 rotates, it drives the first transmission shaft 4 to rotate under the cooperation of the first bearing seat 3 through meshing transmission with the first bevel gear 6. The protrusion 5 is made of flexible rubber. The rotation of the first transmission shaft 4 drives the protrusion 5 to rotate synchronously, thereby striking the side wall of the hopper 1 to prevent the material from sticking to the side wall.

[0023] Refer to the instruction manual appendix Figure 1 and Figure 2 The transmission mechanism includes a support assembly and a drive assembly. The support assembly is used to mount the drive assembly, and the drive assembly is used to drive the second transmission shaft 8 to rotate.

[0024] It should be noted that the drive assembly is mounted on the support assembly, and the drive assembly can drive the second drive shaft 8 to rotate when it is in operation.

[0025] Refer to the instruction manual appendix Figure 1 and Figure 2 The support assembly includes a fixing plate 101 fixed to the front side of the hopper 1, and two support rods 102 are installed at the bottom of the fixing plate 101. The support rods 102 are fixedly connected to the hopper 1.

[0026] It should be noted that the support plate can provide support for the bottom of the fixed plate 101, thereby increasing the support strength of the fixed plate 101.

[0027] Refer to the instruction manual appendix Figure 2 The drive assembly includes a drive motor 103 mounted on the top of the fixed plate 101, a drive gear 104 mounted on the output end of the drive motor 103, and a driven gear 105 mounted on the outer side of the second transmission shaft 8. The drive gear 104 meshes with the driven gear 105.

[0028] It should be noted that when the drive motor 103 is in operation, it can drive the drive gear 104 to rotate. The drive gear 104 meshes with the driven gear 105 to drive the second transmission shaft 8 to rotate.

[0029] Refer to the instruction manual appendix Figure 4 and Figure 5 The positioning component includes an adjustment component and a limiting component. The adjustment component is used to adapt to the external fixed bracket, and the limiting component is used to limit the adjustment component.

[0030] It should be noted that both the adjustment component and the limit component are installed on the rear side of the hopper 1 for installation with the external fixed bracket.

[0031] Refer to the instruction manual appendix Figure 4 and Figure 5 The adjustment assembly includes a mounting frame 111 fixed to the rear side of the hopper 1. A bidirectional lead screw 112 is rotatably connected inside the mounting frame 111. A knob 113 is connected through the right end of the bidirectional lead screw 112 through the mounting frame 111. The knob 113 is used to drive the bidirectional lead screw 112 to rotate. Two movable seats 114 are threadedly connected through the outer side of the bidirectional lead screw 112.

[0032] It should be noted that rotating the knob 113 drives the bidirectional lead screw 112 to rotate, and when the bidirectional lead screw 112 rotates, it drives the two moving seats 114 that are threadedly engaged with it to move relative to each other.

[0033] Refer to the instruction manual appendix Figure 4 and Figure 5 The limiting component includes a limiting frame 115 fixed to the rear side of the hopper 1. A limiting rod 116 is fixed inside the limiting frame 115. Two slides 117 are slidably connected through the outer side of the limiting rod 116. A connecting rod 119 is fixed between the slides 117 and the corresponding moving seat 114. A mounting plate 118 is fixed to the rear side of both the slides 117 and the moving seat 114.

[0034] It should be noted that by setting the connecting rod 119, the slide 117 and the movable seat 114 can be linked together. When the movable seat 114 moves, it can adjust the distance between the two mounting plates 118, so that the mounting plates 118 can be adapted to different external fixed brackets.

[0035] Working principle: Material enters the external vacuum feeder pipe through hopper 1. When the drive motor 103 operates, it drives the drive gear 104 to rotate. The drive gear 104 meshes with the driven gear 105, causing the second drive shaft 8 to rotate in the second bearing seat 7. The second bevel gear 9 on the second drive shaft 8 meshes with the first bevel gear 6 fixed at the front end of the first drive shaft 4, causing the first drive shaft 4 to rotate in the first bearing seat 3. When the first drive shaft 4 rotates, the protrusion 5 fixed on its outer side rotates synchronously, striking the side wall of hopper 1 to prevent material from sticking. At the same time, rotating the knob 113 drives the bidirectional lead screw 112 to rotate in the mounting frame 111. The bidirectional lead screw 112 causes the two moving seats 114 to move relative to each other. The moving seats 114 drive the slide seat 117 to slide on the limit rod 116 through the connecting rod 119, thereby adjusting the distance between the mounting plate 118 fixed on the back of the slide seat 117 and the moving seat 114 to adapt to the external fixed bracket.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
