Description

Technical Field

[0001] This utility model belongs to the field of packaging box forming and processing technology, specifically, it relates to a foam plastic packaging box forming and processing device. Background Technology

[0002] The foam plastic packaging box molding and processing equipment is a professional equipment system used to produce foam plastic packaging boxes. Its core function is to make packaging products with cushioning and heat insulation properties by foaming thermoplastic resins such as polystyrene and polypropylene.

[0003] The prior art discloses a foam box production device with a compaction component (CN218139419U), including a support base. The support base consists of a base plate with support plates symmetrically welded to its upper end. A through groove is formed on the side of the support plate, and grooves are symmetrically formed on both sides of the through groove. A movable groove is symmetrically formed at the lower end of the through groove. A fixed arm is provided between the two support plates. The beneficial effects of this invention are: after the foam box is compacted, the motor shaft drives the main gear to rotate, which in turn drives the transmission gear ring to rotate 180 degrees. The transmission gear ring then drives the lower mold base to rotate 180 degrees via a rotating shaft. Through the cooperation of a shaking mechanism and a reset mechanism, the movable plate shakes up and down. The movable plate, via the rotating shaft, drives the lower mold base to shake up and down, allowing the foam box inside the lower mold base to fall down quickly, thus unloading the formed foam box. The operation is simple and convenient, greatly improving work efficiency.

[0004] Research revealed that existing technologies use a rotating and flipping method to remove foam boxes from the mold base. However, this method ignores the adhesiveness of foam boxes during the thermoplastic molding process, causing the foam to soften and stick to the mold during demolding, resulting in defects in the foam box and affecting its appearance. Furthermore, existing technologies use a single workstation to process and mold foam boxes, which results in relatively low work efficiency and cannot meet the needs of mass production of foam boxes.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A foam plastic packaging box forming and processing device, including

[0008] The base has a control panel installed on one side. An upper mold base and a water-cooled mold base are installed inside the base. The base has a rotating station conversion component that changes the current molding station. The upper mold base is equipped with an air-cooling component for cooling the temperature. The water-cooled mold base is equipped with a water-cooling component for cooling.

[0009] The workstation conversion assembly includes a receiving base, a conversion plate, and a shift lever. A receiving base is fixedly installed at each of the four upper corners of the conversion plate. The conversion plate is rotatably mounted on the bottom inner side of the base. The shift lever is rotatably mounted on the top inner side of the base and moves correspondingly on the conversion plate.

[0010] In a preferred embodiment of this utility model, the base is generally L-shaped, and a hydraulic cylinder is fixedly provided on the top of one side of the base. The output end of the hydraulic cylinder passes through the top of the base and is connected to the top surface of the upper mold base. The control panel is electrically connected to the hydraulic cylinder.

[0011] In a preferred embodiment of the present invention, the air-cooling assembly includes an air supply pipe, an air jet ring pipe, and a telescopic pipe. An air pump is fixedly installed on the top of one side of the base. The air pump is located on one side of the hydraulic cylinder. The air supply pipe is connected to the top of the telescopic pipe through the air pump. The bottom of the telescopic pipe is connected to the air jet ring pipe. The outlet end of the air jet ring pipe is fixed through and fixed to the top of the upper mold base.

[0012] In a preferred embodiment of this utility model, the water-cooling assembly includes a water supply pipe and a circulating water pipe. A circulating water pump is fixedly installed on one outer wall of the base. The water supply pipe is connected to the circulating water pipe through the circulating water pump. Both ends of the circulating water pipe are connected to the circulating water pump. The circulating water pipe is installed inside the water-cooling mold base.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The air-cooling and water-cooling components work together.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] A foam plastic packaging box forming and processing device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including

[0029] The base 10 has a control panel 11 installed on one side. The upper mold base 16 and the water-cooled mold base 17 are installed inside the base 10. The base 10 has a rotating station conversion component that changes the current molding station. The upper mold base 16 is equipped with an air-cooling component for cooling the temperature. The water-cooled mold base 17 is equipped with a water-cooling component for cooling.

[0030] The workstation conversion assembly includes a receiving seat 18, a conversion plate 19, and a shift lever 28. A receiving seat 18 is fixedly installed at each of the four upper corners of the conversion plate 19. The conversion plate 19 is rotatably installed at the bottom inside the base 10. The shift lever 28 is rotatably installed at the top inside the base 10. The shift lever 28 is correspondingly movable on the conversion plate 19.

[0031] like Figure 1 As shown, the base 10 has an overall L-shaped structure. One side of the base 10 is provided with a support frame for processing and molding foam boxes, and the other side of the base 10 is provided with a closed frame for storing the workstation conversion components. A hydraulic cylinder 15 is fixedly provided on the top of one side of the base 10. The output end of the hydraulic cylinder 15 passes through the top of the base 10 and is connected to the top surface of the upper mold base 16. The control panel 11 is electrically connected to the hydraulic cylinder 15.

[0032] Specifically, the partitioned design of the base 10 ensures the openness of the processing area, facilitating operation and observation, while also properly storing complex conversion components to avoid external interference. A hydraulic cylinder 15 is securely mounted on the top side of the base 10, with its output end precisely penetrating the top of the base 10 and firmly connected to the top surface of the upper mold base 16. This ensures that during operation, the upper mold base 16 can move stably and accurately up and down under the drive of the hydraulic cylinder 15, providing reliable pressure for the molding of foam plastic packaging boxes. The control panel 11 is installed on one side of the base 10 for convenient operation and parameter setting by the operator. The control panel 11 establishes an electrical signal connection with the hydraulic cylinder 15, allowing the operator to conveniently control the working status of the hydraulic cylinder 15 through the control panel 11. This allows for precise control of the movement of the upper mold base 16. The air-cooling and water-cooling components work together. The air-cooling component quickly removes heat from the surface of the foam plastic packaging box, initially reducing its temperature. The water-cooling component penetrates deeper into the outer layer of the mold to further cool the foam plastic packaging box, ensuring that its internal structure is completely solidified and reducing quality problems such as product deformation caused by insufficient or uneven cooling. The device is equipped with a station conversion component that enables rapid station conversion without the need for manual mold replacement or waiting for mold reset. The four receiving seats 18 correspond to four different stations, allowing for simultaneous placement of raw materials, followed by sequential and orderly molding and cooling demolding, greatly improving production efficiency and meeting the needs of mass production of foam boxes.

[0033] like Figure 1 and Figure 3 As shown, the air-cooled assembly includes an air supply pipe 14, a jet ring pipe 25, and a telescopic pipe 26. An air pump 24 is fixedly installed on the top of one side of the base 10. The air pump 24 is located on one side of the hydraulic cylinder 15. The air supply pipe 14 is connected to the top of the telescopic pipe 26 through the air pump 24. The bottom of the telescopic pipe 26 is connected to the jet ring pipe 25. The outlet end of the jet ring pipe 25 is fixed through the top of the upper mold base 16. The jet ring pipe 25 consists of a square ring pipe and multiple jet pipes arranged in an array. Multiple through holes are arranged in an array on the upper mold base 16. The square ring pipe is fixed to the top surface of the upper mold base 16 by clamps and bolts. The jet pipes pass through the corresponding through holes. The air supply pipe 14 is connected to an external compressed air machine for supplying compressed air.

[0034] The working principle is as follows: When the equipment is working, the air pump 24 starts, and the external compressed air compressor delivers compressed air to the air pump 24 through the air delivery pipe 14. The air pump 24 further delivers the compressed air to the jet ring pipe 25 through the telescopic pipe 26. Due to the special structure of the jet ring pipe 25, the compressed air can be evenly sprayed from multiple jet pipes and evenly sprayed around the foam plastic packaging box, which cools the foam plastic packaging box formed in the upper mold base 16. The telescopic pipe 26 ensures that even if the upper mold base 16 moves up and down under the drive of the hydraulic cylinder 15 during the operation of the equipment, it will not affect the normal operation of the air cooling components, thus ensuring the continuity and stability of the air cooling.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, the water cooling assembly includes a water supply pipe 13 and a circulating water pipe 21. A circulating water pump 20 is fixedly installed on one outer wall of the base 10. The water supply pipe 13 is connected to the circulating water pipe 21 through the circulating water pump 20. Both ends of the circulating water pipe 21 are connected to the circulating water pump 20. The circulating water pipe 21 is installed inside the water cooling mold base 17.

[0036] like Figure 2 and Figure 4 As shown, the receiving seat 18 is correspondingly set at the bottom of the water-cooled mold base 17. The ejector plate 22 is snapped into the receiving seat 18. An electric push rod 23 is fixedly provided on the bottom surface of the receiving seat 18. The output end of the electric push rod 23 passes through the receiving seat 18 and connects to the bottom surface of the ejector plate 22. The ejector plate 22 slides through the inside of the water-cooled mold base 17.

[0037] The working principle is as follows: the water supply pipe 13 is connected to a cooling water tank. When the circulating water pump 20 is working, it draws the cooling water in the cooling water tank through the water supply pipe 13 and sends it into the circulating water pipe 21. The cooling water circulates in the circulating water pipe 21, carrying away the heat inside the water-cooled mold base 17, thereby cooling the foam plastic packaging box formed inside the water-cooled mold base 17. The circulating water pipe 21 ensures uniform contact and cooling with the mold base inside the water-cooled mold base 17, so that all parts of the foam plastic packaging box are cooled evenly, effectively avoiding product deformation or quality problems caused by uneven cooling.

[0038] like Figure 4 and Figure 5 As shown, a handle 12 is rotatably provided on the outer top surface of one side of the base 10. The output end of the handle 12 passes through the base 10 and is connected to the center of one end of the shift lever 28. A sleeve 27 is fixedly provided at each of the four corners of the conversion disc 19. The electric push rod 23 is embedded in the sleeve 27. The receiving seat 18 is fixedly provided on the top of the sleeve 27.

[0039] like Figure 4As shown, a cross groove 29 is provided at the center of the top surface of the conversion disk 19. The shift lever 28 is set off from the center of the conversion disk 19. The shift lever 28 rotates inside one corner of the cross groove 29. The conversion disk 19 consists of a disk and four connecting plates. The cross groove 29 is provided inside the disk. A sleeve 27 is installed on the top surface of the connecting plate away from the disk.

[0040] The working principle and specific implementation method are as follows: During use, according to production needs, set parameters such as the stroke and speed of the hydraulic cylinder 15, the air output of the air pump 24, and the water flow rate of the circulating water pump 20 on the control panel 11. Rotate the handle 12 to change the workstation to a suitable position, so that the receiving seat 18 is located below the water-cooled mold base 17. Place the foam plastic raw material into the water-cooled mold base 17 and the receiving seat 18. Start the hydraulic cylinder 15; the upper mold base 16 moves downward under the drive of the hydraulic cylinder 15, extruding and molding the foam plastic raw material between the upper mold base 16 and the water-cooled mold base 17. During the molding process, the air pump 24 can be started as needed to assist in cooling the raw material in the upper mold base 16 through the air-cooling component. To ensure molding quality, after molding is completed, the upper mold base 16 moves upward and resets under the drive of the hydraulic cylinder 15. At this time, the circulating water pump 20 is started, and the foam plastic packaging box in the water-cooled mold base 17 is cooled by water cooling components. At the same time, the air cooling components can continue to work to accelerate the cooling speed. After cooling is completed, the electric push rod 23 is started. The electric push rod 23 pushes the ejector plate 22 to eject the foam plastic packaging box from the water-cooled mold base 17. The operator takes out the product and selects to turn the handle 12. The handle 12 drives the shift rod 28 to rotate. Since the shift rod 28 is off the center of the conversion plate 19 and is in the cross groove 29, the rotation of the shift rod 28 will push the conversion plate 19 to rotate a certain angle, thereby realizing the conversion of the work position.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
