Description

Technical Field

[0001] This utility model relates to the field of foam box production technology, specifically to a foam box rapid cooling and shaping frame. Background Technology

[0002] Cooling and shaping are key steps in the production of foam boxes, and cooling and shaping devices are often needed during the shaping process.

[0003] Patent CN222886176U discloses a cooling device for finished foam box production, relating to the field of foam box production and processing technology. It includes a frame, a conveyor belt inside the frame, a power mechanism inside the conveyor belt, a fan hood above the frame, an air duct above the fan hood, a motor outside the air duct, and fan blades fixedly mounted on the output shaft of the motor.

[0004] Although the device utilizes the coordination between the fan shroud, air duct, and motor one—where motor one provides rotational power to drive the fan blades, which in turn drive airflow—and guides the airflow into the fan shroud through the air duct, thus confining the airflow and increasing its utilization rate, and the conveyor belt rotates the foam box to move its position, ensuring even contact with the flowing air and carrying away residual heat, thereby increasing the cooling speed and improving production efficiency, this device relies solely on fan blades for cooling. When the ambient temperature is high, the fan alone is insufficient for rapid cooling of the foam box. Furthermore, it is difficult to evenly distribute the cooler air over the foam box, resulting in long cooling times, high energy consumption, and uneven cooling that affects product strength and stability, reducing product yield. Therefore, we propose a rapid cooling and shaping frame for foam boxes. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid cooling and shaping frame for foam boxes. By setting a cooling mechanism, it solves the problems of traditional cooling methods, such as difficulty in adjusting the cooling position according to the size of the foam box, low cooling efficiency, and uneven cooling.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid cooling and shaping frame for foam boxes includes a work plate, a cooling box fixed to the top surface of the work plate, a door hinged to the front surface of the cooling box via two hinges, several air vents on the top surface of the cooling box, and a placement mechanism for placing the foam box on the inner bottom surface of the cooling box. The frame also includes:

[0008] A cooling mechanism, located inside the cooling box, is used to rapidly cool the foam box placed inside the cooling box. The cooling mechanism includes a vent box, an air outlet pipe fixed to the bottom surface of the vent box and connected to its inner cavity, a rotary joint mounted on the bottom surface of the air outlet pipe, a rotating pipe mounted on the bottom surface of the rotary joint, a jet nozzle mounted on the bottom surface of the rotating pipe, a motor mounted on the bottom surface of the vent box for driving the rotating pipe to rotate, an electric cylinder mounted on the top surface of the cooling box for driving the vent box to lift and lower, and a cold air generator mounted on the top surface of the cooling box for supplying cold air to the inside of the vent box.

[0009] In a preferred embodiment, the placement mechanism includes a placement plate fixed to the bottom surface of the cooling box by a plurality of fixing rods, the top surface of the placement plate is provided with a mounting groove, and a rubber plate is embedded inside the mounting groove on the top surface of the placement plate;

[0010] This design provides a stable placement space for the foam box. The placement mechanism, including the placement plate, fixing rod, and rubber plate, makes the foam box more stable and less prone to damage when placed.

[0011] In a preferred embodiment, the vent box is located inside the cooling box, the cylinder body of the electric cylinder is mounted on the top surface of the cooling box, the piston rod of the electric cylinder passes through the top surface of the cooling box and extends into the cooling box, and the vent box is fixed to the bottom surface of the piston rod of the electric cylinder.

[0012] In a preferred embodiment, the inner cavities of the air outlet pipe and the rotating pipe are both connected to the inner cavity of the rotary joint, the inner cavity of the jet nozzle is connected to the inner cavity of the rotating pipe, and an air inlet pipe connected to its inner cavity is fixed on the left side surface of the air box. The cooling mechanism also includes an air inlet pipe with one end tightly connected to the air outlet of the cold air generator, and the other end of the air inlet pipe is located inside the cooling box. The air inlet pipe is connected to the air inlet pipe through a corrugated pipe. The air inlet pipe, corrugated pipe, air outlet pipe, rotary joint, rotating pipe, and jet nozzle are all located inside the cooling box, and the position of the jet nozzle corresponds to the placement plate and their dimensions are compatible.

[0013] In a preferred embodiment, the vent pipe is provided with a sealing ring at the air outlet and air inlet of the air generator, the vent box is provided with a sealing ring at the air inlet and air outlet, the rotary joint is provided with a sealing ring at the air outlet and rotary tube, and the rotary tube is also provided with a sealing ring at the air jet head.

[0014] In a preferred embodiment, the cooling mechanism further includes a rotating shaft coaxially connected to the motor output shaft, two pulleys located inside the cooling box and connected by belt drive, and the two pulleys are respectively coaxially fixed on the outer circumferential wall of the rotating shaft and the rotating tube;

[0015] These four settings allow the jet head to be adjusted in height according to the size of the foam box, ensure that the cold air can be smoothly delivered to the jet head, guarantee the sealing of the cooling mechanism to prevent cold air leakage, and enable the jet head to rotate and diffuse the cold air.

[0016] In a preferred embodiment, a plurality of support columns arranged in a matrix are fixed on the bottom surface of the working plate, and a support plate is fixed on the bottom surface of the support columns.

[0018] These two features make the entire cooling and shaping rack more stable and make the door easier to open and close; the filter screen of the air vent on the top of the cooling box prevents dust and other impurities from easily entering the cooling box.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model achieves the function of stably placing foam boxes that need to be cooled by setting up a working plate, a cooling box, and a placement mechanism. The placement plate in the placement mechanism is fixed to the bottom surface of the cooling box by a fixing rod, and the rubber plate embedded in the groove on the top surface of the placement plate can not only play a buffering role to avoid damage to the foam box during placement, but also increase the friction between the plate and the foam box, making the foam box more stable and achieving the effect of providing a safe and stable placement environment for cooling the foam box.

[0021] 2. This utility model achieves rapid and efficient cooling of foam boxes through its cooling mechanism. The electric cylinder in the cooling mechanism drives the air box to rise and fall, thereby adjusting the distance between the air jet and the foam box, allowing for adaptive adjustments based on different foam box sizes. The motor drives the rotating pipe and air jet via belt drive, ensuring more even and widespread diffusion of cold air within the cooling box, allowing the foam box to fully contact the cold air. The cold air generator produces cold air and delivers it to the air jet through the air inlet pipe, corrugated pipe, and other components. Compared to traditional water cooling and air cooling methods, this cooling mechanism avoids problems such as water stains and equipment corrosion that may occur with water cooling, and overcomes the shortcomings of low efficiency and uneven cooling in air cooling. It significantly improves the cooling speed and effect of foam boxes, increases production efficiency, and ensures the quality of the foam boxes. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Please see Figure 1 , Figure 3 This utility model provides a technical solution: a foam box rapid cooling and shaping frame, including a working board 1, a cooling box 2 fixed on the top surface of the working board 1, a box door 21 that is hinged to the front surface of the cooling box 2 by two hinges, and a number of air vents on the top surface of the cooling box 2.

[0033] Several support columns 11 arranged in a matrix are fixed on the bottom surface of the working plate 1, and support plates 12 are fixed on the bottom surface of the support columns 11.

[0034] The support columns 11 and support plates 12 on the bottom of the working plate 1 ensure that the cooling and shaping frame is placed stably. The matrix arrangement of the support columns 11 and the support plates 12 increases the contact area with the ground, enhances stability, and prevents equipment shaking from affecting the cooling effect of the foam box and ensuring operational safety.

[0035] A handle 22 is installed on the front surface of the door 21 near the right end. A filter screen 23 is installed inside several air vents on the top surface of the cooling box 2, and the size of the filter screen 23 is adapted to the size of the air vents on the top surface of the cooling box 2.

[0036] The handle 22 of the door 21 makes it easy to open and close the door 21. The handle 22 makes it easy for operators to open and close the cooling box 2 and to place and take out the foam box. The filter screen 23 of the air outlet on the top surface of the cooling box 2 makes it difficult for dust and other impurities to enter the cooling box 2. The filter screen 23 blocks external impurities, keeps the inside of the cooling box 2 clean, prevents contamination of the foam box, and ensures product quality.

[0037] In this embodiment, as Figure 2 , Figure 4 As shown, the inner bottom surface of the cooling box 2 is provided with a placement mechanism 3 for placing foam boxes. The placement mechanism 3 includes a placement plate 31 fixed to the inner bottom surface of the cooling box 2 by a number of fixing rods 32. The top surface of the placement plate 31 is provided with an installation groove, and a rubber plate 33 is embedded in the installation groove on the top surface of the placement plate 31.

[0038] The placement plate 31, fixing rod 32 and rubber plate 33 in the placement mechanism 3 make the foam box stable and not easily damaged. The fixing rod 32 fixes the placement plate 31 to the bottom of the cooling box 2. The mounting groove of the placement plate 31 cooperates with the rubber plate 33 to prevent the foam box from sliding and to buffer and reduce shock, thus protecting the surface quality of the foam box.

[0039] In addition, such as Figures 1-2 , Figures 5-7 As shown, it also includes: a cooling mechanism 4, which is installed inside the cooling box 2 and is used to quickly cool the foam box placed inside the cooling box 2. The cooling mechanism 4 includes a vent box 41, an air outlet pipe 45 fixed to the bottom surface of the vent box 41 and connected to its inner cavity, a rotary joint 46 installed on the bottom surface of the air outlet pipe 45, a rotating pipe 47 installed on the bottom surface of the rotary joint 46, a jet nozzle 48 installed on the bottom surface of the rotating pipe 47, a motor 49 installed on the bottom surface of the vent box 41 and used to drive the rotating pipe 47 to rotate, an electric cylinder 42 installed on the top surface of the cooling box 2 and used to drive the vent box 41 to lift and lower, and a cold air generator 44 installed on the top surface of the cooling box 2 and used to supply cold air to the inside of the vent box 41.

[0040] The vent box 41 is located inside the cooling box 2. The cylinder body of the electric cylinder 42 is installed on the top surface of the cooling box 2. The piston rod of the electric cylinder 42 passes through the top surface of the cooling box 2 and extends into the interior of the cooling box 2. The vent box 41 is fixed on the bottom surface of the piston rod of the electric cylinder 42.

[0041] The electric cylinder 42 allows the jet head 48 to be flexibly adjusted in height. For foam boxes of different sizes, the electric cylinder 42 drives the vent box 41 to raise and lower the jet head 48, precisely controlling the distance of cold air injection to ensure that the cold air acts efficiently on the foam box, thereby improving the cooling effect and applicability.

[0042] The inner cavities of the exhaust pipe 45 and the rotating pipe 47 are connected to the inner cavity of the rotary joint 46. The inner cavity of the jet head 48 is connected to the inner cavity of the rotating pipe 47. An intake pipe 43 connected to its inner cavity is fixed on the left side surface of the ventilation box 41. The cooling mechanism 4 also includes an exhaust pipe 410 with one end tightly connected to the exhaust end of the cold air generator 44. The other end of the exhaust pipe 410 is located inside the cooling box 2. The exhaust pipe 410 is connected to the intake pipe 43 through the corrugated pipe 411. The intake pipe 43, the corrugated pipe 411, the exhaust pipe 45, the rotary joint 46, the rotating pipe 47, and the jet head 48 are all located inside the cooling box 2. The position of the jet head 48 corresponds to that of the placement plate 31 and their sizes are compatible.

[0043] The gas delivery channel, consisting of components such as the vent box 41, the air inlet pipe 43, and the corrugated pipe 411, allows cold air to be stably delivered to the jet head 48. The interconnected design of each component, combined with the flexibility of the corrugated pipe, ensures smooth delivery of cold air and provides a stable cold source for the rapid cooling of the foam box.

[0044] A sealing ring is provided at the part where the vent pipe 410 contacts the outlet end of the air generator 44 and the inlet pipe 43. A sealing ring is provided at the part where the vent box 41 contacts the inlet pipe 43 and the outlet pipe 45. A sealing ring is provided at the part where the rotary joint 46 contacts the outlet pipe 45 and the rotary pipe 47. A sealing ring is also provided at the part where the rotary pipe 47 contacts the jet head 48.

[0045] The sealing rings at the joints of each component ensure good sealing of the cooling mechanism 4, prevent cold air leakage, maintain the concentration of cold air in the cooling box 2, reduce energy loss, improve cooling efficiency, and ensure that the foam box can be quickly shaped in a sufficient cold air environment.

[0046] The cooling mechanism 4 also includes a rotating shaft 414 coaxially connected to the output shaft of the motor 49, and two pulleys 412 located inside the cooling box 2 and connected by a belt 413. The two pulleys 412 are coaxially fixed on the outer circumference of the rotating shaft 414 and the rotating tube 47, respectively.

[0047] The motor 49, rotating shaft 414, pulley 412 and belt 413 enable the jet head 48 to rotate and diffuse the cold air. The motor 49 drives the rotating shaft 414 to rotate, and the belt 413 drives the jet head 48 to rotate, expanding the coverage of the cold air and allowing the foam box to come into full contact with the cold air, resulting in more uniform and efficient cooling.

[0048] It should be added that the air conditioning generator 44, electric cylinder 42, and motor 49 are all electrically connected to an external PLC via wires, and the air conditioning generator 44, electric cylinder 42, and motor 49 are all electrically connected to an external power supply via wires, and the external PLC is also electrically connected to an external power supply via wires.

[0049] Finally, it should be noted that the components involved in this utility model, such as the air-generating device 44, electric cylinder 42, and motor 49, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0050] In this embodiment, during actual use, the operator first opens the box door 21, places the foam box on the top surface of the rubber plate 33 of the placement mechanism 3, and then closes the box door 21.

[0051] Subsequently, the cold air generator 44 is activated by sending a command through an external PLC. The generated cold air enters the ventilation box 41 through the ventilation pipe 410, the corrugated pipe 411, and the air inlet pipe 43, and then passes through the air outlet pipe 45, the rotary joint 46, and the rotating pipe 47 in sequence, and is finally ejected by the jet nozzle 48.

[0052] At the same time, the external PLC controls the electric cylinder 42 to start, and adjusts the height of the jet head 48 according to the size of the foam box to ensure that the cold air is sprayed accurately. Then, the external PLC controls the motor 49 to start. The motor 49 drives the rotating pipe 47 and the jet head 48 to rotate through the rotating shaft 414, pulley 412 and belt 413, so that the cold air is evenly diffused in the cooling box 2 and contacts the foam box in all directions to achieve rapid cooling.

[0053] After cooling is complete, the external PLC controls the motor 49 and the air generator 44 to stop working, the electric cylinder 42 resets, and the operator opens the box door 21 to take out the cooled and shaped foam box, thus ending the entire cooling process.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
