Description

Technical Field

[0001] This utility model relates to a material bag feeding device, specifically an automatic material bag feeding device for thermoplastic resin processing, belonging to the technical field of material bag feeding devices. Background Technology

[0002] Thermoplastic resin is a material that softens when heated and hardens when cooled. Its characteristic is that no chemical reaction occurs during heating and cooling, so it can be reused multiple times. In the processing of thermoplastic resin, the raw material inside the bag needs to be fed into the processing equipment. Generally, a robotic arm automatically grabs the bag and moves it to the top of the feeding hopper. Then, the bag is moved so that the bottom of the bag comes into contact with the bag-breaking blade at the top of the feeding hopper. At this time, the bag-breaking blade will cut the bag, and the raw material inside the bag will fall into the feeding hopper under the action of gravity, thus realizing the automatic feeding of the bag.

[0003] However, a certain amount of dust is generated during the feeding process. This dust will pollute the surrounding environment when it is dispersed into the air, resulting in poor environmental friendliness. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding device for thermoplastic resin processing to solve the above problems. This device can remove dust generated during the feeding process, thus avoiding pollution to the surrounding environment and effectively improving the environmental friendliness of the device.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an automatic feeding device for thermoplastic resin processing, comprising a feeding hopper, a dust removal structure on the feeding hopper, the dust removal structure comprising a dust suction hood and a first connecting pipe, two dust suction hoods fixedly connected to the feeding hopper, a first connecting pipe fixedly connected to the dust suction hood, a second connecting pipe fixedly connected to the feeding hopper, one end of each of the two first connecting pipes fixedly connected to both sides of the second connecting pipe, a flange fixedly connected to one end of the second connecting pipe, an outer frame snapped onto the dust suction hood, a filter screen fixedly connected to the outer frame, and a fixing structure on the dust suction hood.

[0006] Preferably, the two dust hoods are symmetrically distributed about the middle of the feeding hopper, and the feeding hopper has an overall conical structure.

[0007] Preferably, the fixing structure includes a connecting seat and a rotating shaft. Two connecting seats are fixedly connected to both sides of the dust collection cover. A rotating shaft is rotatably connected to the connecting seat. A stop block is rotatably connected to the rotating shaft. The stop block abuts against the outer frame. The outer frame is provided with two slots.

[0008] Preferably, the width of the stop block cross section is smaller than the width of the slot cross section, and the stop block and the rotating shaft form an L-shaped structure.

[0009] Preferably, a connecting rod is fixedly connected to the feeding hopper, and a bag-breaking blade is installed on the connecting rod.

[0010] Preferably, the feeding hopper has an opening, and a protective net is fixedly connected inside the feeding hopper.

[0011] Preferably, a support frame is fixedly connected to the feeding hopper, and four support plates are fixedly connected to the bottom end of the support frame.

[0012] Preferably, the support plate has four mounting holes, and the support frame and the support plate form a T-shaped structure.

[0013] The beneficial effects of this utility model are as follows: During use, the air inlet pipe of the bag filter can be connected to the flange at the end of the second connecting pipe. Therefore, during the feeding process, dust will enter the interior of the two dust collection hoods under the action of the bag filter, and then enter the interior of the first connecting pipe, and then enter the interior of the second connecting pipe from the two first connecting pipes, and finally enter the interior of the bag filter for dust removal. This avoids dust generated during the feeding process from drifting into the air and causing pollution to the surrounding environment, effectively improving the environmental friendliness of the use. By setting a filter screen, large objects can be prevented from entering the dust collection system and causing blockage, thus effectively improving the stability of use. By removing the outer frame from the dust collection hood, the surface of the filter screen can be cleaned, thus preventing dust from clogging the mesh of the filter screen and causing a decrease in suction power, thereby effectively improving the stability of use.

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.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an automatic feeding device for thermoplastic resin processing includes a feeding hopper 1. The feeding hopper 1 is equipped with a dust removal structure 2, which includes a dust suction hood 201 and a first connecting pipe 202. Two dust suction hoods 201 are fixedly connected to the feeding hopper 1, and the first connecting pipe 202 is fixedly connected to the dust suction hood 201. A second connecting pipe 203 is fixedly connected to the feeding hopper 1. One end of each of the two first connecting pipes 202 is fixedly connected to both sides of the second connecting pipe 203. A flange 204 is fixedly connected to one end of the second connecting pipe 203. An outer frame 205 is snapped onto the dust suction hood 201, and a filter screen 206 is fixedly connected to the outer frame 205. A fixing structure 3 is provided on the dust suction hood 201.

[0021] As a technical optimization solution of this utility model, such as Figure 1 and Figure 2 As shown, the two dust hoods 201 are symmetrically distributed about the middle of the feeding hopper 1. The feeding hopper 1 has an overall conical structure. Therefore, by setting two dust hoods 201, dust can be sucked up better, thereby improving the dust removal effect.

[0022] As a technical optimization solution of this utility model, such as Figure 2 and Figure 3As shown, the fixing structure 3 includes a connecting seat 301 and a rotating shaft 302. Two connecting seats 301 are fixedly connected to both sides of the dust collection cover 201. The rotating shaft 302 is rotatably connected to the connecting seat 301. A stop block 303 is rotatably connected to the rotating shaft 302. The stop block 303 abuts against the outer frame 205. The outer frame 205 is provided with two slots 304, so the outer frame 205 can be quickly disassembled, which facilitates the cleaning of the filter screen 206.

[0023] As a technical optimization solution of this utility model, such as Figure 3 As shown, the width of the cross section of the stop block 303 is smaller than the width of the cross section of the slot 304. The stop block 303 and the rotating shaft 302 form an L-shaped structure, so the stop block 303 can pass through the slot 304, thereby realizing the disassembly of the outer frame 205.

[0024] As a technical optimization solution of this utility model, such as Figure 1 and Figure 2 As shown, a connecting rod 5 is fixedly connected to the feeding hopper 1, and a bag-breaking blade 6 is installed on the connecting rod 5, so that the bag can be cut open by the bag-breaking blade 6.

[0025] As a technical optimization solution of this utility model, such as Figure 1 and Figure 2 As shown, the feeding hopper 1 has an opening 7, and a protective net 4 is fixedly connected inside the feeding hopper 1, so as to prevent large debris from entering the inside of the feeding hopper 1.

[0026] As a technical optimization solution of this utility model, such as Figure 1 and Figure 2 As shown, a support frame 8 is fixedly connected to the feeding hopper 1, and four support plates 9 are fixedly connected to the bottom end of the support frame 8, so that the support frame 8 can support the feeding hopper 1.

[0027] As a technical optimization of this utility model, the support plate 9 is provided with four mounting holes 10, and the support frame 8 and the support plate 9 are in a T-shaped structure. Therefore, the support plate 9 can be installed and fixed by bolts through multiple mounting holes 10, thereby realizing the installation and fixing of the feeding device.

[0028] In use, this utility model connects the inlet pipe of the bag filter to the flange 204 at the end of the second connecting pipe 203. During feeding, a robotic arm grabs the material bag to the top of the feeding hopper 1. As the bag moves, the bag-breaking blade 6 cuts the bottom of the bag, and the material inside falls into the feeding hopper 1 under gravity, thus achieving automatic feeding. A protective net 4 prevents debris from entering the feeding hopper 1. A support frame 8 supports the feeding hopper 1, and a support plate 9 increases the contact area between the support frame 8 and the ground, improving stability. Bolts and mounting holes 10 allow the support plate 9 to be installed on the ground, securing the feeding device. During feeding, dust enters the two dust collection hoods 201 under the action of the bag filter, and then enters the second dust collection hood 203. The material enters the interior of a connecting pipe 202, then from the two first connecting pipes 202 into the interior of a second connecting pipe 203, and finally into the interior of a bag filter for dust removal. This prevents dust generated during the feeding process from being dispersed into the air and polluting the surrounding environment, effectively improving the environmental friendliness of the system. By setting up a filter screen 206, large objects can be prevented from entering the dust removal system and causing blockages, thus effectively improving the stability of operation. By rotating the two baffles 303 180 degrees, they are no longer obstructing the outer frame 205, and then the outer frame 205 can be removed from the dust collection hood 201. The filter screen 206 can be removed along with the outer frame 205, making it convenient to clean the dust on the surface of the filter screen 206. This prevents dust from clogging the mesh of the filter screen 206 and causing a decrease in suction power, thus effectively improving the stability of operation.
