Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a ton bag feeding device for epoxy resin production. Background Art

[0002] In the production of epoxy resin, a variety of raw materials, including silica powder, resin, etc., need to be put into production in a certain proportion, and after stirring and extrusion, the finished products are formed; in the feeding production link, a gantry crane is required to lift the ton bag above the feeding rack and put the materials in the ton bag into the leakage hopper. Since the ton bag is large and the materials inside are heavy, congestion and stagnation will occur when the materials fall, resulting in difficulty for the materials to enter the leakage hopper.

[0003] When the existing feeding device guides the feeding of materials, it drives a push plate with an inclined angle to push the ton bag, so that the materials in the ton bag can smoothly fall into the feeder. Since the materials in the ton bag contain silica powder, dust will be generated in the leakage hopper during the feeding process, causing the silica powder to spread into the surrounding environment and easily affecting the health of the staff. Content of the Utility Model

[0004] The technical problems solved by this solution are as follows:

[0005] (1) How to solve the problem that dust is generated in the leakage hopper during the feeding process, causing the silica powder to spread into the surrounding environment and easily affecting the health of the staff.

[0006] The purpose of the utility model can be achieved by the following technical solutions: a ton bag feeding device for epoxy resin production, including a working frame and a mounting plate fixedly installed in the middle thereof. A leakage hopper for collecting materials is fixedly inserted on the mounting plate. A cleaning mechanism for processing the residual materials in the ton bag is arranged on the mounting plate on one side of the leakage hopper. A shielding mechanism for preventing the diffusion of silica powder is arranged between the cleaning mechanism and the leakage hopper.

[0007] The shielding mechanism includes a U-shaped shielding cover fixedly connected to the top of the leakage hopper. A rotating seat is fixedly installed at the bottom of the opening of the U-shaped shielding cover. A turning plate is rotatably arranged on the top of the rotating seat. An inclined plate is fixedly connected to the side of the turning plate away from the U-shaped shielding cover. The inclined surface of the inclined plate faces the mounting plate. A positioning block for limiting the turning plate is fixedly installed on the inner wall of the U-shaped shielding cover.

[0008] A further technical improvement of the utility model lies in that: a cylinder is fixedly inserted on the mounting plate. A first roller is rotatably arranged at the top of the extending end of the cylinder, and a trapezoidal block is fixedly installed in the middle of the extending end of the cylinder. The first roller is in rolling connection with the inclined plate.

[0009] A further technical improvement of the present utility model lies in that: the cleaning mechanism includes an adjusting cylinder fixedly connected to the mounting plate. Both sides of the top of the adjusting cylinder are respectively communicated with a first hose and a second hose. The output end of the first hose penetrates through the turning plate and corresponds to the position of the positioning block. The output end of the second hose is provided with an impact unit for impacting the ton bag.

[0010] A further technical improvement of the present utility model lies in that: an air pump is further provided on the mounting plate. The output end of the air pump is communicated with the middle part of the adjusting cylinder through an air inlet pipe. A first piston is slidably arranged on the inner wall of the adjusting cylinder. A transmission rod is fixedly connected to the side surface of the first piston. One end of the transmission rod movably penetrates through the adjusting cylinder and a second roller is rotatably arranged. The position of the second roller corresponds to the position of the trapezoidal block. A thrust spring is elastically arranged between the side surface of the first piston away from the transmission rod and the inner wall of the adjusting cylinder. By controlling the extension of the extending end of the cylinder to the longest, the first roller rolls on the inclined plate, so that the turning plate rotates to the set position. At this time, the turning plate contacts the positioning block. Due to the action of the thrust spring, the first piston is located between the output end of the air inlet pipe and the input end of the first hose. Then the air pump is turned on, and the air flow entering the adjusting cylinder enters the guide pipe through the second hose, pushing the second piston to slide towards the exhaust hole. After the second piston passes through the exhaust hole, the second piston is pulled back to its original position by the tension spring, so that the second piston makes a reciprocating movement, driving the impact head to continuously impact the middle part of the ton bag, thereby facilitating the feeding of the materials inside the ton bag into the leakage hopper. At the same time, the dust-proof area formed by the U-shaped shielding cover and the turning plate shields the silicon powder diffused during feeding, preventing it from polluting the surrounding environment and affecting the health of the staff.

[0011] A further technical improvement of the present utility model lies in that: the impact unit includes a guide pipe fixedly inserted on the turning plate. A second piston is slidably arranged on the inner wall of the guide pipe. An impact rod is fixedly connected to the side surface of the second piston. One end of the impact rod movably penetrates through the guide pipe and an impact head is fixedly installed.

[0012] A further technical improvement of the present utility model lies in that: an exhaust hole is opened on the middle side wall of the guide pipe. A tension spring is fixedly connected between the side surface of the second piston away from the impact rod and the inner wall of the guide pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] When the utility model is in use, by controlling the extension end of the cylinder to extend to the longest, the first roller rolls on the inclined plate, so that the turning plate rotates to a set position. At this time, the turning plate contacts the positioning block. Due to the action of the thrust spring, the first piston is located between the output end of the air inlet pipe and the input end of the first hose. Then, the air pump is turned on, and the air flow entering the adjusting cylinder enters the guide pipe through the second hose, pushing the second piston to slide towards the exhaust hole. After the second piston passes through the exhaust hole, the second piston is pulled back to its original position by the tension spring, so that the second piston moves reciprocally, driving the impact head to continuously impact the middle of the ton bag, thereby facilitating the feeding of the materials inside the ton bag into the leakage hopper. At the same time, the dust-proof area formed by the U-shaped shielding cover and the turning plate shields the silicon powder diffused during feeding, avoiding its pollution of the surrounding environment and affecting the health of the staff.

[0024] Please refer to Figures 1-3 As shown in the figure, the above-mentioned cleaning mechanism 3 includes an adjusting cylinder 35 fixedly connected to the mounting plate 5. The two sides of the top of the adjusting cylinder 35 are respectively communicated with a first hose 31 and a second hose 32. The output end of the first hose 31 penetrates through the turning plate 66 and corresponds to the position of the positioning block 65. The output end of the second hose 32 is provided with an impact unit for impacting the bulk bag.

[0025] Please refer to Figures 1-3As shown in the figure, an air pump 4 is further provided on the above-mentioned mounting plate 5. The output end of the air pump 4 is communicated with the middle of the adjusting cylinder 35 through an air inlet pipe 34. A first piston 33 is slidably arranged on the inner wall of the adjusting cylinder 35. A transmission rod 36 is fixedly connected to the side surface of the first piston 33. One end of the transmission rod 36 movably penetrates through the adjusting cylinder 35 and is rotatably provided with a second roller. The position of the second roller corresponds to the position of the trapezoidal block 62. A thrust spring is elastically arranged between the side surface of the first piston 33 away from the transmission rod 36 and the inner wall of the adjusting cylinder 35. By controlling the extension of the extending end of the air cylinder 63 to the longest, the first roller 61 rolls on the inclined plate 64, so that the turning plate 66 rotates to a set position. At this time, the turning plate 66 contacts the positioning block 65. Due to the action of the thrust spring, the first piston 33 is located between the output end of the air inlet pipe 34 and the input end of the first hose 31. Then, the air pump 4 is turned on. The air flow entering the adjusting cylinder 35 enters the guide pipe 37 through the second hose 32, pushing the second piston to slide towards the exhaust hole. After the second piston passes through the exhaust hole, the second piston is pulled back to its original position by the tension spring, causing the second piston to move reciprocally, driving the impact head to continuously impact the middle of the ton bag, so as to facilitate the feeding of the materials inside the ton bag into the leakage hopper 7. At the same time, the dust-proof area formed by the U-shaped shielding cover 8 and the turning plate 66 shields the silicon powder diffused during feeding, avoiding polluting the surrounding environment and affecting the health of the staff.

[0026] Please refer to Figures 1-3 As shown in the figure, the above-mentioned impact unit includes a guide pipe 37 fixedly inserted on the turning plate 66. A second piston is slidably arranged on the inner wall of the guide pipe 37. An impact rod is fixedly connected to the side surface of the second piston.

The end of the guide pipe 37 away from the impact head is communicated with the output end of the second hose 32.

[0027] Please refer to Figure 3 As shown in the figure, an exhaust hole is opened on the middle side wall of the above-mentioned guide pipe 37. A tension spring is fixedly connected between the side surface of the second piston away from the impact rod and the inner wall of the guide pipe 37.

[0028] Please refer to Figure 1 As shown in the figure, a hook 1 for placing a ton bag is fixedly installed on the top of the above-mentioned working frame 2.

[0029] Working principle: When the utility model is in use, first, the extending end of the air cylinder 63 is at the shortest position, and the turning plate 66 does not block the opening of the U-shaped shielding cover 8. The ton bag is passed through the opening of the U-shaped shielding cover 8 by an external transfer device, and its top is hung on the hook 1. The bottom of the ton bag is opened, and the materials inside it are slowly put into the leakage hopper 7; then, the extending end of the air cylinder 63 is controlled to extend to the longest. The first roller 61 rolls on the inclined plate 64, so that the turning plate 66 rotates to the set position. At this time, the turning plate 66 contacts the positioning block 65; due to the action of the thrust spring, the first piston 33 is located between the output end of the air inlet pipe 34 and the input end of the first hose 31. Then, the air pump 4 is started, and the air flow entering the adjusting cylinder 35 enters the guiding pipe 37 through the second hose 32, pushing the second piston to slide towards the exhaust hole. After the second piston passes through the exhaust hole, the second piston is pulled back to its original position by the tension spring, so that the second piston makes a reciprocating movement, driving the impact head to continuously impact the middle part of the ton bag, thereby facilitating the materials inside the ton bag to be put into the leakage hopper 7. At the same time, the dust-proof area formed by the U-shaped shielding cover 8 and the turning plate 66 shields the silicon powder diffused during feeding, preventing it from polluting the surrounding environment and affecting the health of the staff; after the materials in the ton bag are put out, the extending end of the air cylinder 63 is controlled to contract to the shortest, so that the first roller 61 is separated from the inclined plate 64. At this time, the second roller rolls along the inclined surface of the trapezoidal block 62 to the side away from the air cylinder 63, so that the transmission rod 36 pushes the first piston 33 to slide between the output end of the air inlet pipe 34 and the input end of the second hose 32, so that the air flow enters the first hose 31 and then is ejected from the output end of the first hose 31, cooperating with the positioning block 65 to block it, providing a reaction force to the turning plate 66, so that the turning plate 66 is reset and turned over, facilitating the unloading of the empty ton bag.
