Description

Technical Field

[0001] This utility model relates to the field of cover film production technology, specifically a plastic granule hot-melt device for cover film production. Background Technology

[0002] Plastic cover film production often utilizes screw extruders. Plastic granules and modified materials are added to the screw extruder, where they melt and mix to produce plastic with the desired properties. Screw extruders typically use hoppers to hold the materials, but these hoppers generally only function to hold and discharge the materials. The plastic needs to be heated to a molten state inside the screw extruder to ensure uniform mixing with the modified materials. However, screw extruders generally use external heating, which results in longer heating times, lower efficiency, and hinders plastic processing, making it inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a plastic granule hot-melting device for producing cover film, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

The machine body includes a feeding port, the feeding mechanism is located above the feeding port, and the heating mechanism is fixedly connected to the bottom end of the feeding mechanism. The heating mechanism includes a fixing ring, which is detachably connected to the machine body. A rotating ring is rotatably sleeved on the inner side wall of the fixing ring, and the bottom surface of the rotating ring has multiple outflow holes. A cylinder is fixedly connected to the top surface of the rotating ring, and a connecting shell is provided inside the cylinder. A connecting cylinder is provided on the outer side wall of the cylinder, and both ends of the connecting cylinder are fixedly sleeved with fixing cylinders. One end of the two fixing cylinders is opposite to the other and is fixedly connected to the top surface of the fixing ring and the feeding mechanism, respectively. An annular shell is fixedly sleeved on the outer side wall of each of the two fixing cylinders. Electric heating devices are provided inside the connecting shell and the two annular shells. The ejection mechanism is fixedly connected to the two fixing cylinders.

[0007] Furthermore, the cylinder has a sealed structure at both ends, and the outer wall of the cylinder is provided with multiple protruding spike-like structures.

[0008] Furthermore, both the fixed cylinder and the connecting cylinder are made of copper.

[0009] Furthermore, the feeding mechanism includes:

[0010] The device includes a hopper for holding materials, a connecting plate, and a motor housing. The bottom of the hopper is fixedly connected to the top surface of an adjacent fixed cylinder. The connecting plate is fixedly connected to the top of the hopper. A pipe is rotatably connected to the top surface of the connecting plate, and the bottom of the pipe is fixedly connected to the top of the cylinder. A toothed ring is fixedly fitted onto the outer wall of the pipe, and multiple stirring rods are fixedly connected to the outer wall of the pipe. The motor housing is fixedly connected to the top surface of the connecting plate. A drive motor is installed inside the motor housing, and a gear is fixedly connected to the motor shaft of the drive motor. The gear meshes with the toothed ring.

[0011] Furthermore, the inner wall of the hopper is fixedly fitted with a partition, and the top surface of the partition is provided with multiple connecting grooves. The inner wall of the hopper is rotatably fitted with a collar, and the inner wall of the collar is fixedly connected with multiple baffles. One end of any baffle is fixedly connected to the outer wall of the pipe body, and the multiple baffles correspond one-to-one with the multiple connecting grooves.

[0012] Furthermore, the ejection mechanism includes:

[0013] The device comprises a ring body, multiple internally threaded cylinders, multiple arc-shaped plates capable of ejecting cooled plastic, and multiple sliding rods. Multiple support rods are fixedly connected between the ring body and the outer walls of the two fixed cylinders. One end of each internally threaded cylinder is rotatably connected to the inner wall of the ring body. Multiple arc-shaped plates are located inside the connecting cylinder. Multiple grooves are formed on the inner wall of the connecting cylinder, and each groove corresponds to one of the arc-shaped plates. Each arc-shaped plate is embedded within its corresponding groove. Multiple sliding rods correspond to one of the arc-shaped plates. One end of each sliding rod is fixedly connected to the center of one side of the corresponding arc-shaped plate, and the other end penetrates the outer wall of the connecting cylinder and is fixedly connected to a screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By connecting the fixed plate to the machine body, the drive motor is started, which drives the tube to rotate through gears and a gear ring. This causes the tube to intermittently disengage multiple baffles from the connecting groove, allowing material on the baffles to intermittently fall into the space between the cylinder and the connecting cylinder. Then, the electric heating equipment is started to heat the cylinder and the connecting cylinder. The thin space between the cylinder and the connecting cylinder improves the heating effect of the plastic, thus preheating the plastic before it is discharged into the machine body, reducing the preheating time of the plastic and improving the processing efficiency of the plastic. The tube can also drive the cylinder to rotate, causing the protrusions on the cylinder to agitate the plastic, facilitating the expulsion of air from the plastic. After use, coolant can be injected into the metal pipe to cool the cylinder and the connecting cylinder, causing the plastic between the cylinder and the connecting cylinder to solidify. Then, the internal threaded cylinder is rotated to move the arc plate and push the solidified plastic, while the cylinder is rotated at the same time, which facilitates the removal of residual plastic from the cylinder and the connecting cylinder, making it convenient for the user.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 In this embodiment of the present invention, a plastic granule hot-melting device for producing a cover film includes:

[0025] The machine body 100, capable of melting and mixing plastics, includes a feeding mechanism 200, a heating mechanism 300 for preheating the plastics, and an ejection mechanism 400. The machine body 100 includes a feeding inlet, the feeding mechanism 200 is located above the feeding inlet, and the heating mechanism 300 is fixedly connected to the bottom end of the feeding mechanism 200. The heating mechanism 300 includes a fixing ring 310, which is detachably connected to the machine body 100. A rotating ring 311 is rotatably sleeved on the inner wall of the fixing ring 310, and the bottom surface of the rotating ring 311 has multiple outflow holes. A cylinder 320 is fixedly connected to the top surface, and a connecting shell is provided inside the cylinder 320. A connecting cylinder 330 is provided on the outer wall of the cylinder 320, and a fixed cylinder 340 is fixedly sleeved at both ends of the connecting cylinder 330. The two fixed cylinders 340 are fixedly connected to the top surface of the fixed ring 310 and the feeding mechanism 200 respectively at opposite ends. An annular shell 341 is fixedly sleeved on the outer wall of the two fixed cylinders 340. Electric heating devices are provided inside the connecting shell and the two annular shells 341. The ejection mechanism 400 is fixedly connected to the two fixed cylinders 340.

[0026] Specifically, the machine body 100 is a screw extruder. The retaining ring 310 can be fixed to the feed inlet of the machine body 100 using a connector. Then, the material is fed into the feeding mechanism 200, causing the material to fall between the barrel 320 and the connecting cylinder 330. The annular shell 341 and the connecting shell are then heated by activating the electric heating device, and the temperature is transferred to the barrel 320 and the connecting cylinder 330, thus raising the temperature of the plastic between the barrel 320 and the connecting cylinder 330. Because the space between the barrel 320 and the connecting cylinder 330 is relatively thin, it is easier to increase the temperature of the plastic between the barrel 320 and the connecting cylinder 330. The heating effect is improved, and the plastic between the cylinder 320 and the connecting cylinder 330 can be stirred by rotating the cylinder 320, which facilitates the discharge of air after the plastic melts. The melted plastic can then be discharged into the machine body 100 through the outlet hole, thereby improving the heating effect of the plastic. The plastic is preheated before entering the machine body 100, reducing the preheating time of the plastic and facilitating the processing of the plastic. Stirring the melted plastic also facilitates the discharge of air in the plastic. The connecting shell can be connected to the outside through a rigid pipe so that the connecting shell does not rotate when the cylinder 320 rotates. The electric heating equipment is existing technology and will not be described in detail here.

[0027] Example 1

[0028] like Figure 4 As shown, in this embodiment, the cylinder 320 has a sealed structure at both ends, and the outer wall of the cylinder 320 is provided with multiple protruding spike structures. The two fixed cylinders 340 and the connecting cylinder 330 are all made of copper.

[0029] In this embodiment, the contact surface between the fixed cylinder 340 and the connecting cylinder 330 is relatively large, which allows for more uniform temperature transfer. When the electric heating device inside the annular shell 341 is activated and the annular shell 341 is heated, the heat from the annular shell 341 can be conducted by the copper with good thermal conductivity on the fixed cylinder 340, making the temperature of the fixed cylinder 340 more uniform. Then, the heat from the two fixed cylinders 340 can be conducted to the connecting cylinder 330, making the temperature of the connecting cylinder 330 more uniform. When the cylinder 320 rotates, it can use its own convex structure to stir and melt the plastic, which facilitates the expulsion of air from the plastic.

[0030] like Figure 1-2 and Figure 5 As shown, in this embodiment, the feeding mechanism 200 includes:

[0031] The system includes a hopper 210 for holding materials, a connecting plate 220, and a motor housing 240. The bottom of the hopper 210 is fixedly connected to the top surface of an adjacent fixed cylinder 340. The connecting plate 220 is fixedly connected to the top of the hopper 210. A pipe 221 is rotatably connected to the top surface of the connecting plate 220, and the bottom of the pipe 221 is fixedly connected to the top of the cylinder 320. A toothed ring is fixedly fitted onto the outer wall of the pipe 221, and multiple stirring rods 222 are fixedly connected to the outer wall of the pipe 221. The motor housing 240 is fixedly connected to the top surface of the connecting plate 220. The box 240 is equipped with a drive motor, and the motor shaft of the drive motor is fixedly connected to a gear 241. The gear 241 meshes with a gear ring. A partition 211 is fixedly sleeved on the inner wall of the hopper 210, and multiple connecting slots 212 are opened on the top surface of the partition 211. A collar 230 is rotatably sleeved on the inner wall of the hopper 210, and multiple baffles 231 are fixedly connected to the inner wall of the collar 230. One end of any baffle 231 is fixedly connected to the outer wall of the tube 221. The multiple baffles 231 correspond one-to-one with the multiple connecting slots 212.

[0032] In practice, the material is fed into the hopper 210 and naturally accumulates on the partition plate 211. The baffle plate 231 blocks the connecting groove 212. Then, the drive motor is started, which drives the gear ring and the tube body 221 to rotate through the gear 241. This causes the tube body 221 to drive the cylinder 320 to rotate synchronously. The tube body 221 can also cause the baffle plate 231 to intermittently move away from the connecting groove 212. When the baffle plate 231 does not block the connecting groove 212, the material piled on the partition plate 211 can naturally fall into the space between the cylinder 320 and the connecting cylinder 330 through the connecting groove 212. This allows for intermittent feeding into the space between the cylinder 320 and the connecting cylinder 330, preventing excessive material from affecting the heating effect of the plastic. When the tube body 221 rotates, it can also drive the stirring rod 222 to stir the material on the partition plate 211, making it easier for the material to pass through the connecting groove 212.

[0033] like Figure 2-4 As shown, in this embodiment, the ejection mechanism 400 includes:

[0034] The system comprises a ring body 410, multiple internally threaded cylinders 420, multiple arc-shaped plates 430 capable of ejecting cooled plastic, and multiple sliding rods 440. Multiple support rods are fixedly connected between the ring body 410 and the outer walls of the two fixed cylinders 340. One end of each of the multiple internally threaded cylinders 420 is rotatably connected to the inner wall of the ring body 410. The multiple arc-shaped plates 430 are located inside the connecting cylinder 330. Multiple grooves 331 are provided on the inner wall of the connecting cylinder 330, and each groove 331 corresponds to one of the multiple arc-shaped plates 430. Each arc-shaped plate 430 is embedded in the corresponding groove 331. Each of the multiple sliding rods 440 corresponds to one of the multiple arc-shaped plates 430. One end of each sliding rod 440 is fixedly connected to the center of one side of the corresponding arc-shaped plate 430, and the other end passes through the outer wall of the connecting cylinder 330 and is fixedly connected to a screw 441. Each of the multiple screws 441 corresponds to one of the multiple internally threaded cylinders 420, and each screw 441 is screwed into the corresponding internally threaded cylinder 420.

[0035] In practice, after the material is fed in, the electric heating equipment is turned off. The connecting shell and the two annular shells 341 all have metal pipes inside. By injecting coolant into these metal pipes, the pipes come into contact with the inner walls of the connecting shell or annular shell 341, allowing the coolant to cool the connecting shell or annular shell 341. This causes the plastic remaining in the space between the cylinder 320 and the connecting cylinder 330 to solidify upon cooling. The rigid pipe connected to the connecting shell is located inside the pipe body 221, and this rigid pipe prevents the connecting shell from rotating when the cylinder 320 rotates. Then, the inner... The threaded cylinder 420 drives the adjacent arc plate 430 to push out the adjacent groove 331. At the same time, the drive motor is started to drive the tube body 221 and the cylinder 320 to rotate through the gear 241 and the gear ring, making it easier for the solidified plastic to detach from the cylinder 320 and the connecting cylinder 330. Then, the solidified plastic is clamped out with pliers through the connecting groove 212, which makes it easier for the user to clean the space between the cylinder 320 and the connecting cylinder 330. The metal pipe can be a heat exchange pipe, which is existing technology and will not be described in detail here. The metal pipe can be laid in various parts of the annular shell 341 and the connecting shell as needed.

[0036] Example 2

[0037] Based on Embodiment 1, the exhaust pipe 213 and the frustum shell 223 are provided to facilitate use by the user.

[0038] like Figure 1 and Figure 5 As shown, in this embodiment, a frustum shell 223 is fixedly sleeved on the outer wall of the tube 221, and the frustum shell 223 is fixedly connected to the top of the cylinder 320. An exhaust pipe 213 is fixedly connected to the outer wall of the hopper 210, and the exhaust pipe 213 is located below the partition plate 211.

[0039] In practice, the frustum shell 223 facilitates the material to roll down its inclined surface into the space between the cylinder 320 and the connecting cylinder 330, thus guiding the material. The exhaust pipe 213 allows the air in the plastic between the cylinder 320 and the connecting cylinder 330 to be discharged, making it convenient for users to operate.
