Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for an extruder used in the production of thermoplastic elastomers. Background Technology

[0002] Thermoplastic elastomers, also known as synthetic rubber or artificial rubber, possess the excellent properties of traditional cross-linked vulcanized rubber, such as high elasticity, aging resistance, and oil resistance, while also having the advantages of ordinary plastics, such as ease of processing and wide range of processing methods. In the production process of thermoplastic elastomers, extruders are usually used for processing. However, during the use of the extruder, it is necessary to continuously add material particles into the extruder. Usually, the material bags containing the material particles need to be manually moved to the feeding hopper, which results in a relatively high workload for the workers. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Please see Figure 1-5In this embodiment of the present invention, the feeding device of the extruder for producing thermoplastic elastomers includes a lifting module 100 and a feeding module 200.

[0034] The lifting module 100 is capable of lifting materials;

[0035] The feeding module 200 is located at the bottom of the lifting module 100. The feeding module 200 includes a fixed frame 210. Lifting mechanisms 220 are provided on both sides of the inner side of the fixed frame 210. A support frame 240 and a receiving frame 250 are slidably connected to the inner side of the fixed frame 210. The bottom surface of the support frame 240 is fixedly connected to the top surface of the receiving frame 250. Several round rods 241 are provided on the inner side of the support frame 241. Both ends of the round rods 241 are rotatably connected to sliding seats 242 that are slidably connected to the inner side of the support frame 240. A telescopic cloth tube 243 is fixedly connected to the side of the sliding seat 242. The inner side of the support frame 242 is fixedly connected to the end of the telescopic cloth tube 243 on the side away from the lifting module 100. The telescopic cloth tube 243 is fixedly connected between two adjacent sliding seats 242, and the telescopic cloth tube 243 blocks the space between two adjacent sliding seats 242.

[0036] Specifically, the material bag can be conveyed onto the support frame 240. Due to the inclined setting of the support frame 240, the material bag will slide down along the round rod 241 onto the support frame 240. The support frame 240 can support the material bag through the round rod 241. Then, the support frame 240 can be lifted by the lifting mechanism 220. In this way, after the material bag is opened, the material can slide out of the bag and fall to the bottom of the lifting module 100. The lifting module 100 lifts the material to the discharge port of the extruder. The support frame 240 is relatively low, and the lifting mechanism 220 lifts the material bag, which makes it easy to transport the material bag onto the support frame 240, thus reducing the workload of the workers.

[0037] Example 1

[0038] like Figure 2-4 As shown, in this embodiment, a fixing rod 230 is fixedly connected to the top surface of the fixing frame 210, and a plurality of plug-in rods 231 are fixedly connected to the bottom surface of the fixing rod 230. The fixing rod 230 is located on the side of the fixing frame 210 away from the lifting module 100.

[0039] The lifting mechanism 220 includes a connecting frame 221, a sliding frame 222, and a hydraulic rod 223;

[0040] The connecting frame 221 is fixedly connected to the inner side of the fixed frame 210. The sides of the support frame 240 and the receiving frame 250 are slidably connected to the sides of the connecting frame 221. The sliding frame 222 is slidably connected to the inner side of the connecting frame 221. The sides of the support frame 240 and the receiving frame 250 are fixedly connected to the sides of the sliding frame 222. The hydraulic rod 223 is fixedly connected to the inner bottom surface of the connecting frame 221. The output end of the hydraulic rod 223 is connected to the inner top surface of the sliding frame 222. The hydraulic rod 223 can support the support frame 240 and the receiving frame 250 through the sliding frame 222.

[0041] In practice, after the material bag is moved onto the support frame 240, the sliding frame 222 can be moved upward by the hydraulic rod 223. The sliding frame 222 can drive the support frame 240 and the receiving frame 250 to move upward, thereby raising the material bag to facilitate the pouring out of the material. After the material bag is raised, the insertion rod 231 can be inserted into the material bag to restrict the position of the material bag.

[0042] like Figure 1-2 As shown, in this embodiment, the lifting module 100 includes a lifting frame 110, two transmission rollers 120, a transmission belt 130, and two pads 140.

[0043] The lifting frame 110 is fixedly connected to the inner side of the fixed frame 210. A support frame 111 is fixedly connected to the side of the lifting frame 110. A U-shaped frame 112 is fixedly connected to the top of the side of the lifting frame 110. The U-shaped frame 112 is located at the top opening of the lifting frame 110. A power motor is installed at the top of the side of the lifting frame 110. Two transmission rollers 120 are rotatably connected to the inner side of the lifting frame 110. The output end of the power motor is connected to the end of the top transmission roller 120. A transmission belt 130 is connected to the two transmission rollers 120. Several push plates 131 are fixedly connected to the side of the transmission belt 130. Two pads 140 are fixedly connected to the inner side of the lifting frame 110.

[0044] A partition plate 211 is fixedly connected to the inner side of the fixed frame 210. The sides of the support frame 240 and the receiving frame 250 are slidably connected to the side of the partition plate 211. A guide plate 212 is fixedly connected to the side of the partition plate 211 and is fixedly connected to the side of the lifting frame 110. The guide plate 212 corresponds to the bottom opening of the lifting frame 110.

[0045] In specific implementation, after the support frame 240 and the receiving frame 250 are raised by the lifting mechanism 220 so that the receiving frame 250 corresponds to the top of the partition 211, and the position of the material is restricted by the insertion rod 231, the material bag can be opened. At this time, the material in the material bag can pass through the round rod 241 and fall onto the receiving frame 250, and then slide down along the receiving frame 250 onto the guide plate 212. The material on the guide plate 212 can pass through the bottom opening of the lifting frame 110 and fall into the lifting frame 110. At this time, the top transmission roller 120 can be driven to rotate by the power motor. The transmission roller 120 can drive the transmission belt 130 to move. The transmission belt 130 can push the material to move through the push plate 131, thereby lifting the material to the top of the lifting frame 110. When the push plate 131 moves to the position of the U-shaped frame 112 after passing the top transmission roller 120, the material can pass through the top opening of the lifting frame 110 along the push plate 131 and fall into the U-shaped frame 112, and then fall from the U-shaped frame 112 into the feed port of the extruder.

[0046] Example 2

[0047] Based on Example 1, such as Figure 5-6 As shown, in this embodiment, several limiting ropes 245 are provided on both sides of the inner side of the support frame 240 corresponding to the sliding seats 242. The opposite surfaces of two adjacent sliding seats 242 are fixedly connected to the ends of the corresponding limiting ropes 245. The inner side of the support frame 240 is fixedly connected to the end of the connecting rope 244 on the side away from the lifting module 100. Both ends of the limiting ropes 245 are fixed on the corresponding sliding seats 242. The position of adjacent sliding seats 242 can be restricted inside the support frame 240 by the limiting ropes 245. The position of adjacent sliding seats 242 can be restricted by the limiting ropes 245, thereby maintaining the position of several round rods 241.

[0048] A drive motor 251 is fixedly connected to the inner side of the receiving frame 250. The output end of the drive motor 251 is connected to a winding rod 252 that is rotatably connected to the inner side of the support frame 240. A connecting rope 1 244 and a connecting rope 246 are fixedly connected to the side of the sliding seat 242 located near the lifting module 100. The connecting rope 1 244 passes through the interior of several sliding seats 242 and is wound around the side of the winding rod 252. One end of the connecting rope 246 passes around the bottom of the support frame 240 and extends into the interior of the receiving frame 250. One end of the connecting rope 246 is wound around the side of the winding rod 252.

[0049] In practice, after the support frame 240 is raised and the material bag is opened, the drive motor 251 can drive the winding rod 252 to rotate. The winding rod 252 can wind up the connecting rope 1 244 and release the connecting rope 246. In this way, the connecting rope 1 244 can pull the sliding seat 242 located away from the drive motor 251 to move, causing the corresponding round rod 241 to move. This allows the end of the material bag to hang down, allowing the material in the material bag to fall out smoothly. The sliding seat 242 can push the adjacent sliding seat 242 to move, thus allowing several round rods to move. Rod 241 moves sequentially toward drive motor 251, allowing the material in the material bag to fall out smoothly without the need for manual emptying, which helps reduce the workload of workers. After the material is emptied, drive motor 251 can be used to rotate the winding rod 252 in the opposite direction, thereby releasing connecting rope 1 244 and winding up connecting rope 246. After tightening connecting rope 246, it can be used to pull the corresponding sliding seat 242 to move, thereby moving the sliding seat 242 and the round rod 241 to their original positions.
