Description

Technical Field

[0001] The present invention relates to the technical field of thermoplastic panel manufacturing equipment, and particularly to a feeding hopper for thermoplastic panel injection molding with an anti-blocking function. Background Technique

[0002] Thermoplastics have high molecular weight, and polymer chains are bound by intermolecular forces, which weaken rapidly with increasing temperature, producing a viscous liquid. In this state, thermoplastics can be reshaped. Thermoplastic sheets are used as raw materials to manufacture plastic products through thermoforming. During forming, a sheet cut into a certain size and fixed shape is clamped on a set frame and heated to the thermoelastic state, and then, by applying pressure, it is made to conform to the mold surface, thus obtaining a shape similar to the mold surface. After cooling and solidifying, it is taken out of the mold and, after appropriate trimming, becomes a thermoformed product. The characteristics of thermoformed products are thin walls because the thickness of the sheet used as the raw material is generally only 1 - 2 mm, and the thickness of the final product is always smaller than this value. The production process of thermoformed products is simple, the equipment cost is low (especially the mold), the production efficiency is high, and the economic benefit is good. For the production of plastic products with less strict requirements for geometric dimensions and shapes, it is a forming method worthy of priority consideration.

[0003] There are many types of raw materials for manufacturing thermoplastic panels, such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, and polyoxymethylene, etc. To ensure the melting rate of raw materials during the panel manufacturing process, the raw materials are usually in the form of granules. The process of manufacturing the panel includes steps such as raw material transportation, material melting, liquid material extrusion, and cooling and forming. When transporting the raw materials, a feeding hopper is usually used to achieve this.

[0004] However, the existing feeding hoppers have the following deficiencies:

[0005] The hopper is divided into two parts, namely a material receiving bin and a feeding pipe. To ensure that materials do not scatter during the feeding process, the feeding pipe is usually directly inserted into the heating component. As a result, the high temperature released inside the heating component will affect some positions of the feeding pipe, causing the temperature of some inner walls of the pipe to continue to increase. Due to the relatively simple internal structure of the existing equipment, it is impossible to control the falling rate of materials inside the equipment, resulting in too many materials coming into contact with the inside of the pipe. Under the action of high temperature, the materials in contact with it will melt, and finally cover the inner wall of the pipe, gradually reducing the inner diameter of the feeding pipe, and ultimately causing the problem of material blockage inside the equipment.

[0006] Therefore, we propose a feeding hopper for thermoplastic panel injection molding with an anti-blocking function to facilitate solving the problems mentioned above. Summary of the Invention

[0007] The object of the present invention is to provide a feeding hopper for thermoplastic panel injection molding with anti-blocking function. Due to the restriction of the baffle on the material, the falling rate of the material is controlled. At this time, the driving device in the material stirring mechanism is started to drive the pushing plate to continuously stir the material in the storage sleeve. At this time, the material in contact with the moving track of the pushing plate will be pressed by the side of the pushing plate and squeezed into part of the discharge holes and fall into the inner part of the blanking pipe. At the same time, because the quantity of the material falling in each stage is small, the probability of the material contacting the inner wall of the blanking pipe is smaller. At the same time, the driving component in the air-cooling cooling mechanism is started. The cold air generated by the operation of the fan blades inside it will be discharged from the air outlet pipe and continuously blow on the surface of the blanking pipe. At the same time, the low temperature will continuously penetrate into the inner part of the blanking pipe, so that the inner wall of the blanking pipe always maintains a relatively constant temperature range.

A hollow shell is fixedly installed on the inner wall of the installation hole, and a group of stoppers are fixedly installed on the inner wall of the hollow shell.

The outer wall of the transmission rod B is movably arranged inside the limiting sleeve B.

[0014] Preferably, the outer wall of the transmission rod B is fixedly sleeved with a joint, and the outer wall of the joint is movably arranged inside the hollow shell. A group of metal elastic sheets are fixedly inserted on the outer wall of the hollow shell.

[0019] Preferably, the outer wall of the inner connecting ring A is fixedly installed on the inner wall of the storage sleeve, and the outer wall of the installation hole is fixedly inserted into the interior of the storage sleeve to determine the connection relationship between the inner connecting ring A and the installation hole and the overall device.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Through the material stirring mechanism and the air-cooling temperature reduction mechanism of the present invention, after the materials are poured into the interior of the storage sleeve, due to the restriction of the baffle on the materials, the falling rate of the materials is controlled. At this time, the driving device in the material stirring mechanism is started to drive the pushing plate to continuously stir the materials in the storage sleeve. At this time, the materials in contact with the moving track of the pushing plate will be pressed on the side of the pushing plate and squeezed into some of the discharge holes and fall into the interior of the blanking pipeline. At the same time, because the quantity of materials falling in each stage is small, the probability of contact between the materials and the inner wall of the blanking pipeline is smaller. Meanwhile, the driving component in the air-cooling temperature reduction mechanism is started, and the cold air generated by the rotation of the fan blades inside it will be discharged from the air outlet pipeline and continuously blow on the surface of the blanking pipeline. At the same time, the low temperature will continuously penetrate into the interior of the blanking pipeline, so that the inner wall of the blanking pipeline always maintains a relatively constant temperature range. The device controls the falling rate of the materials and the temperature of the inner wall of the blanking pipeline to avoid the phenomenon that the materials melt after contacting the heated inner wall of the pipe, effectively solving the deficiencies existing in the prior art, preventing the melted materials from covering the inner wall of the pipe and causing the reduction of the inner diameter of the pipe, and reducing the probability of material blockage in the device.

[0022] 2. The present invention is provided with an oscillation generating mechanism, which utilizes the mutual contact between the driving components and the structure of the mechanism to generate a strong vibration effect. Since the hollow shell is located inside the storage sleeve, the external force generated can directly act on the inside of the storage sleeve. When the material is squeezed into the discharge hole under the push of the push plate, the vibration effect inside the storage sleeve can accelerate the material to quickly detach from the inner wall of the discharge hole.

[0023] 3. The present invention is provided with a material detection mechanism. When the material in the storage sleeve is completely released, the movable buckle without material support will move toward the inside of the storage sleeve under the action of the active spring, and make the contact head separate from the surface of the sensor. At the same time, the information obtained in the sensor will be quickly input into the interior of the receiver, and the alarm light and the speaker will be controlled to turn on. Finally, the eyes and ears of the operator will be stimulated by the transmission of light and sound, reminding the operator that the required materials need to be added to the equipment.

[0037] according to Figures 5-6 As shown, the vibration generating mechanism 4 includes a mounting hole 401, and the mounting hole 401 is opened on the outer wall of the material storage sleeve 1. A hollow shell 402 is fixedly installed on the inner wall of the mounting hole 401, and a group of blocks 403 are fixedly installed on the inner wall of the hollow shell 402. Through the connection relationship between the hollow shell 402 and the material storage sleeve 1, the vibration force generated by the mechanism can be directly applied to the interior of the material storage sleeve 1.

[0038] according to Figure 6 As shown, a U-shaped frame 404 is welded to the outer wall of the storage sleeve 1, a group of metal frames 405 are fixedly inserted into the outer wall of the U-shaped frame 404, an external sleeve ring 406 is fixedly sleeved between the outer walls of the group of metal frames 405, and a servo motor B407 is fixedly inserted into the inner wall of the external sleeve ring 406.

[0039] according to Figure 6 As shown, a limiting sleeve B408 is fixedly installed on the outer wall of the servo motor B407, and a transmission rod B409 is fixedly installed on the output end of the servo motor B407. The outer wall of the transmission rod B409 is movably arranged inside the limiting sleeve B408. By setting the limiting sleeve B408, the left and right swing amplitude of the transmission rod B409 during rotation is effectively limited, thereby improving the stability of the servo motor B407 during operation.

[0040] As shown in Figure 6 Figure, the outer wall of the transmission rod B409 is fixedly sleeved on the joint 410, the outer wall of the joint 410 is movably arranged inside the hollow shell 402, and a group of metal elastic pieces 411 are fixedly inserted on the outer wall of the hollow shell 402. By arranging the metal elastic pieces 411, the shock effect generated by continuously impacting the surface of the hollow shell 402 driven by the driving component is utilized to provide conditions for improving the falling of the material.

[0041] As shown in Figure 8 Figure, the material detection mechanism 6 includes an installation hole 601, the installation hole 601 is opened on the inner wall of the storage sleeve 1, a sensor 602 is arranged inside the storage sleeve 1, and the wiring terminal of the sensor 602 is connected to the internal wiring in the storage sleeve 1. By arranging the sensor 602, the volume of the material is detected through the signal generated by the contact between the object and the surface of the sensor 602.

[0042] As shown in Figures 8-9 Figure, an active spring 603 is welded on the inner wall of the installation hole 601, a movable buckle 604 is fixedly installed on the outer wall of the active spring 603, a connecting rod 605 is fixedly inserted inside the movable buckle 604, and a contact head 606 is fixedly sleeved on the outer wall of the connecting rod 605. By arranging the active spring 603, the movable buckle 604 can be made to have the ability to move flexibly by using its own characteristics, so as to control the contact between the contact head 606 and the sensor 602.

[0043] As shown in Figure 2 Figure, a receiver 607 is fixedly installed on the outer wall of the storage sleeve 1, the wiring terminal of the receiver 607 is connected to the internal wiring in the storage sleeve 1, a group of alarm lights 608 are arranged on the outer wall of the storage sleeve 1, a rectangular groove 609 is opened on the outer wall of the receiver 607, a loudspeaker is arranged inside the rectangular groove 609, and a slotted baffle is fixedly installed on the inner wall of the rectangular groove 609. By arranging the rectangular groove 609 and the loudspeaker, the filling of the material in the storage sleeve 1 can be timely reminded to nearby operators by the transmission of light and sound, stimulating their vision and hearing.

[0044] As shown in Figures 1-3 and Figure 7 Figure, a feeding port 8 is opened on the top of the top cover 7, a group of material guiding channels 9 are fixedly communicated with the bottom of the top cover 7, and a group of handrails 10 are welded on the outer wall of the top cover 7. By arranging the material guiding channels 9, when the material is poured from the feeding port 8, the material guiding channels 9 can be used to guide the material, preventing the smaller materials from directly falling into the driving component.

[0045] As shown in Figures 1-3As shown, the outer surface wall of the inner connecting ring A301 is fixedly installed on the inner surface wall of the material storage sleeve 1, and the outer surface wall of the installation hole 401 is fixedly inserted into the inside of the material storage sleeve 1 to determine the connection relationship between the inner connecting ring A301 and the installation hole 401 and the overall device.

[0046] The effect achieved by the entire mechanism is as follows: When the device is connected to the injection molding device, first insert the top cover 7 equipped with the material guiding channel 9 into the space formed by every two support rods 302 in sequence. Finally, the bottom of the top cover 7 fully contacts the top of the material storage sleeve 1, and then pour the material to be processed from the feed port 8. At this time, the material will continuously pour into the inside of the material storage sleeve 1 from the material guiding channel 9.

[0047] When the device discharges materials, start the servo motor A304 in the connecting sleeve 303 and act on the transmission rod 306 to drive the pushing plate 308 on the connecting collar 307 to rotate evenly, thereby pushing the materials in contact with it. During this process, when some materials contact the discharge hole 311 and are pressed under the bottom of the pushing plate 308, the materials are extruded into the inner wall of the discharge hole 311 and finally fall into the inside of the discharge pipe 2.

[0048] When the compression molding device works, start the fresh air unit 502 in the grafting plate 501. The fan blades inside rotate and generate strong cold air, which is continuously transported through the air transportation pipe 507 and flows into the inside of the intersection ring box 505. Due to the continuous injection of cold air, the air pressure inside the intersection ring box 505 gradually increases. Finally, the cold air retained in the intersection ring box 505 will be evenly discharged from the air outlet pipe 506 and blow on the surface of the discharge pipe 2. When the cold air in the air flow penetrates into the inside of the discharge pipe 2, the temperature control of the inner wall of the discharge pipe 2 is realized.

[0049] When the device is discharging materials, start the servo motor B407 in the external collar 406 and act on the transmission rod B409 to drive the joint 410 equipped with the metal elastic sheet 411 to rotate inside the hollow shell 402. At this time, multiple metal elastic sheets 411 will continuously impact on the surface of the block 403 and produce a strong shock effect. The vibration force will continuously act on the inside of the material storage sleeve 1 to increase the rate of the material falling from the metal elastic sheet 411. When the metal elastic sheet 411 contacts the surface of the block 403, the metal elastic sheet 411 will deform under the extrusion effect. When the metal elastic sheet 411 detaches from the block 403, it will rebound to its original state again and provide conditions for the subsequent impact on the block 403.

[0050] As the material in the storage sleeve 1 is gradually released, when the material is fully pressed on the surface of the movable buckle 604, the active spring 603 is in a compressed state. At this time, the movable buckle 604 is in contact with the material, and the reaction force generated by the active spring 603 will push the movable buckle 604 to move toward the inside of the storage sleeve 1, and drive the contact head 606 on the connecting rod 605 to separate from the surface of the sensor 602. The signal obtained in the sensor 602 is quickly transmitted to the inside of the receiver 607 through the internal wiring of the equipment, and the receiver 607 controls the opening of the alarm light 608 and the speaker, emitting light and sound respectively, to remind the operator to fill the material inside the storage sleeve 1 in time.

[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
