Description

Technical Field

[0001] This utility model relates to the field of foam plastic molding machine technology, and in particular to a feeding structure for a foam plastic molding machine. Background Technology

[0002] A foam plastic molding machine is a device that heats and melts plastic raw materials, forms a porous structure through the action of a foaming agent, and finally solidifies into a specific shape. The feeding structure of the foam plastic molding machine is one of the core auxiliary systems. Its core function is to accurately, stably, and without loss deliver granular raw materials to the mold cavity of the molding machine or the pre-foaming machine.

[0003] Traditional foam plastic molding machines use feeding structures that suffer from high friction during raw material transport, leading to insufficient material flowability, increased feeding difficulty, and impacting production efficiency and product quality stability. Furthermore, the lack of precise metering devices for additive injection makes it impossible to accurately control the amount of detergent injected, often relying on manual experience or simple valve control, which can result in inaccurate detergent injection and compromise the quality of foam plastic molding. Therefore, those skilled in the art have provided a feeding structure for foam plastic molding machines to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a feeding structure for a foam plastic molding machine. Through a feeding and mixing device, it ensures that the laundry detergent adheres evenly to the surface of the raw material inside the feed tank, thereby improving the fluidity of the raw material by increasing the frictional force of the raw material during feeding.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding structure for a foam plastic molding machine, comprising a support frame and a material box, wherein the material box is located at the center of the upper end face of the support frame, a transparent PC barrel is provided at the center of the inside of the material box, four movable wheels are arranged in a rectangle at the center of the lower end face of the support frame, and a feeding and mixing device is provided on one side of the center of the upper end face of the material box.

[0006] The feeding and mixing device includes a metering pump, which is located on the upper end face of the material box. An input pipe is provided at the input end of the metering pump, a conveying hopper is provided at the input port of the input pipe, a storage tank is provided at the upper port of the conveying hopper, and an output pipe is provided at the output end of the metering pump. A rotary motor is provided at the center of the upper end face of the support frame, and a rotating rod is provided at the center of the inside of the transparent PC barrel. Four stirring blades are arranged in a rectangle at the center of the outer side of the rotating rod, and an adaptive stirring structure is provided at one end of each of the four stirring blades.

[0007] Through the above technical solution, the laundry detergent is stored in the storage tank by the staff, then transported by the conveyor bucket, and the injection volume of the laundry detergent can be accurately controlled by the metering pump. This ensures that the injection volume of the laundry detergent is not erroneous and avoids uneven foaming or performance fluctuations of the foam plastic caused by the imbalance of the ratio, thereby ensuring the molding quality of the foam plastic. Then, the rotating motor drives the rotating rod, which in turn drives the stirring blade to rotate and stir, so as to meet the condition that the laundry detergent is evenly attached to the surface of the raw material inside the material tank. This also realizes the friction of the raw material during feeding, thereby improving the flowability of the raw material.

[0008] Furthermore, the output pipe passes through the material box and the transparent PC barrel in sequence and extends to the inner wall of the transparent PC barrel;

[0009] The above technical solution, through the through-hole of the output pipe, enables the laundry detergent to be smoothly injected into the transparent PC drum for mixing.

[0010] Furthermore, the output end of the rotary motor passes through the material box and the transparent PC barrel in sequence and extends into the interior of the transparent PC barrel, and is fixedly connected to the end of the rotating rod;

[0011] Through the above technical solution, by passing through the output end of the rotary motor and fixing it to the rotating rod, the rotary motor can smoothly drive the stirring blades inside the transparent PC tub to rotate and stir, thus achieving the mixing of laundry detergent and raw materials.

[0012] Furthermore, a cap is fitted over the upper end of the storage tank;

[0013] The above technical solution forms a physical barrier by tightly sealing the upper port of the storage tank, isolating the internal space of the storage tank from the external environment, preventing external air, dust, moisture and other impurities from entering the storage tank, and avoiding contamination or oxidation of the laundry detergent.

[0014] Furthermore, the adaptive stirring structure on one side includes a square groove, which is located at the center of one side of the stirring blade and extends through one side of the stirring blade to an inner wall. The center of the upper and lower inner walls of the stirring blade is provided with a sliding groove on one side. A fixed block is slidably connected to the center of the stirring blade on one side. A slider is provided at the center of both the upper and lower end faces of the fixed block. A rubber block is provided on one side of the slider. An extension blade is provided on one side of the rubber block.

[0015] Through the above technical solution, the fixed block can slide and move in the groove of the stirring blade. The square groove provides guidance and limit to ensure the accuracy of movement. When the stirring blade rotates, the rubber block, as a flexible material, deforms during the contact with the material during rotation, which extends the blade to adjust the angle and increases the effective mixing area. This extends the mixing effect to the dead corners and inner wall areas near the container wall, thereby ensuring the overall uniformity of mixing and improving the mixing effect.

[0016] Furthermore, the fixing block and the rubber block are slidably connected to the square groove respectively;

[0017] The above technical solution allows for the extension and movement of the extension blades by slidingly connecting the fixed block and the rubber block with the square groove.

[0018] Furthermore, a controller is provided at the front center of the upper end face of the support frame;

[0019] The above technical solution enables the controller to receive flow sensor signals from the metering pump or output pipe, accurately calculate the amount of laundry detergent injected, monitor the real-time speed of the rotating motor, achieve precise speed regulation through the frequency converter, and feed this information back to the controller. The actuator is responsible for performing specific operations. This is a commonly used technical method in existing control systems, and will not be elaborated on further here.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when using the feeding structure of the foam plastic molding machine, the worker stores the laundry detergent into the storage tank, then conveys it through the conveying hopper, and the metering pump can accurately control the amount of laundry detergent injected, ensuring that the amount of laundry detergent injected is within tolerance and avoiding uneven foaming or performance fluctuations in the foam plastic due to imbalance in the ratio, thereby ensuring the quality of foam plastic molding. Then, the rotating motor drives the rotating rod, which in turn drives the stirring blade to rotate and stir, so as to meet the condition that the laundry detergent is evenly attached to the surface of the raw material inside the material box, realizing the friction of the raw material during feeding, thereby improving the fluidity of the raw material.

[0022] 2. In this utility model, the fixed block can slide and move in the groove of the stirring blade. The square groove provides guidance and limit to ensure the accuracy of movement. When the stirring blade rotates, the rubber block, as a flexible material, deforms during the rotation process when it comes into contact with the material, which extends the blade to adjust the angle and increases the effective mixing area. This extends the mixing effect to the dead corners and inner wall areas near the container wall, thereby ensuring the overall uniformity of mixing and improving the mixing effect.

[0030] 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.

[0031] Reference Figure 1-5 This utility model provides an embodiment of a feeding structure for a foam plastic molding machine, including a support frame 1 and a material box 2. The material box 2 is located at the center of the upper end face of the support frame 1. A transparent PC barrel 3 is located at the center of the inside of the material box 2. Four moving wheels 4 are arranged in a rectangle at the center of the lower end face of the support frame 1. A feeding mixing device 5 is located on one side of the center of the upper end face of the material box 2. The feeding mixing device 5 ensures that the laundry detergent is evenly attached to the surface of the raw material inside the material box 2, and realizes the friction of the raw material during feeding, thereby improving the flowability of the raw material.

[0032] The adaptive stirring structure 6 includes a square groove 601, which is located at the center of one side of the stirring blade 509 and extends through one side of the stirring blade 509 to an inner wall. Sliding grooves 602 are provided at the center of both the upper and lower inner walls of the stirring blade 509, near one side. A fixed block 603 is slidably connected to the center of the stirring blade 509, near one side. A slider 604 is provided at the center of both the upper and lower end faces of the fixed block 603. A rubber block 605 is provided on one side of the slider 604, and an extension blade 606 is provided on one side of the rubber block 605. The fixed block 603 can slide within the sliding groove 602 of the stirring blade 509. The square groove 601 provides guidance and limitation to ensure motion accuracy. When the stirring blade 509 rotates, the rubber block 605, as a flexible material, deforms during contact with the material, allowing the extension blade 606 to adjust its angle, increasing the effective stirring area and extending the mixing action to the dead corners and inner wall areas near the container wall, thereby ensuring overall mixing uniformity and improving the stirring effect.

[0033] The fixing block 603 and the rubber block 605 are slidably connected to the square groove 601, so that the extension blade 606 can be extended and moved.

[0034] A controller 7 is located at the front center of the upper end face of the support frame 1. The controller 7 receives the flow sensor signal from the metering pump 501 or the output pipe 506, accurately calculates the amount of laundry detergent injected, and monitors the real-time speed of the rotary motor 507. The speed is precisely adjusted by the frequency converter, and this information is fed back to the controller 7. The actuator is responsible for performing the specific operation. This is a common technical means in existing control systems, and will not be elaborated on here.

[0035] like Figure 1 , 2As shown in Figures 3 and 4, the feeding and mixing device 5 includes a metering pump 501, which is located on the upper surface of the material box 2. An input pipe 502 is located at the input end of the metering pump 501, and a conveying hopper 503 is located at the input port of the input pipe 502. A storage tank 504 is located at the upper port of the conveying hopper 503. An output pipe 506 is located at the output end of the metering pump 501. A rotary motor 507 is located at the center of the upper surface of the support frame 1. A rotating rod 508 is located at the center of the interior of the transparent PC barrel 3. Four stirring blades 509 are arranged in a rectangular pattern at the center of the outer side of the rotating rod 508. Each of the four stirring blades 509 has an adaptive stirring structure at one end. 6. The laundry detergent is stored in the storage tank 504 by the staff, and then transported by the conveyor hopper 503. The metering pump 501 can accurately control the amount of laundry detergent injected, ensuring that the amount of laundry detergent injected is accurate and avoiding uneven foaming or performance fluctuations of the foam plastic due to the imbalance of the ratio, thereby ensuring the quality of foam plastic molding. Then, the rotary motor 507 drives the rotating rod 508, which in turn drives the stirring blade 509 to rotate and stir, so as to meet the condition that the laundry detergent is evenly attached to the surface of the raw material inside the material box 2, and realize the friction of the raw material during feeding, thereby improving the flowability of the raw material.

[0036] The output pipe 506 passes through the material box 2 and the transparent PC bucket 3 in sequence and extends to the inner wall of the transparent PC bucket 3. The passage of the output pipe 506 enables the laundry detergent to be smoothly injected into the transparent PC bucket 3 for mixing.

[0037] The output end of the rotary motor 507 passes through the material box 2 and the transparent PC barrel 3 in sequence and extends into the interior of the transparent PC barrel 3. It is fixedly connected to the end of the rotating rod 508. Through the passage of the output end of the rotary motor 507 and its fixed connection with the rotating rod 508, the rotary motor 507 can smoothly drive the stirring blades 509 inside the transparent PC barrel 3 to rotate and stir, thus achieving the mixing of laundry detergent and raw materials.

[0038] A cap 505 is fitted onto the upper port of the storage tank 504. The cap 505 is tightly fitted onto the upper port of the storage tank 504 to form a physical barrier, which isolates the internal space of the storage tank 504 from the external environment, preventing external air, dust, moisture and other impurities from entering the storage tank 504 and avoiding contamination or oxidation of the laundry detergent.

[0039] Working principle: When the foam plastic molding machine is used with the feeding structure, the controller 7 receives the flow sensor signal from the metering pump 501 or the output pipe 506 to accurately calculate the amount of laundry detergent injected, and monitors the real-time speed of the rotary motor 507. The speed is precisely adjusted by the frequency converter, and this information is fed back to the controller 7. The actuator is responsible for performing the specific operation. This is a common technical means in the existing control system, and will not be elaborated on here.

[0040] The laundry detergent is stored in the storage tank 504 by staff, then conveyed by the conveyor hopper 503. The metering pump 501 precisely controls the amount of laundry detergent injected, ensuring that the injection amount is accurate and avoiding uneven foaming or performance fluctuations in the foam plastic caused by imbalance in the ratio. This ensures the quality of the foam plastic molding. The rotary motor 507 drives the rotating rod 508, which in turn drives the stirring blade 509 to rotate and stir. This ensures that the laundry detergent is evenly attached to the surface of the raw material inside the material tank 2, and achieves friction during material feeding, thereby improving the flowability of the raw material. Finally, the cap 505 is tightly fitted onto the upper port of the storage tank 504, forming a physical barrier to isolate the internal space of the storage tank 504 from the external environment. This prevents external air, dust, moisture and other impurities from entering the storage tank 504, avoiding contamination or oxidation of the laundry detergent.

[0041] When the stirring blade 509 rotates, its centrifugal force drives the fixed block 603 to slide in the groove 602 of the stirring blade 509. The square groove 601 provides guidance and limit to ensure the accuracy of the movement. The rubber block 605, as a flexible material, deforms during the rotation process when it comes into contact with the material, which extends the blade 606 to adjust the angle and increase the effective mixing area. This extends the mixing effect to the dead corners and inner wall areas near the container wall, thereby ensuring the overall uniformity of mixing and improving the mixing effect.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
