[0002] In the technical field of storage box manufacturing, the appearance design, structural strength and durability of storage boxes have always been important considerations in the production process. With the increasing diversification of market demands and the continuous improvement of consumers' requirements for product quality, the wrapping treatment of the storage box skin has become particularly important.

[0003] The wrapping of the storage box skin usually includes the process of closely fitting decorative materials on the surface of the storage box matrix. Most of the traditional devices for wrapping the storage box skin have problems such as single function, low automation degree, unsatisfactory edge treatment effect, complex operation, and difficulty in meeting the requirements of large-scale production. Therefore, an extrusion device for wrapping and hemming the skin of a storage box is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages of single function, low automation degree, unsatisfactory edge treatment effect, complex operation, and difficulty in meeting the requirements of large-scale production in the prior art, and to propose an extrusion device for wrapping and hemming the skin of a storage box.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An extrusion device for wrapping and hemming the skin of a storage box, including a device main body. A wrapping and hemming mechanism for wrapping the skin on the storage box and hemming is provided on the inner wall of the top of the device main body, and a support and extrusion mechanism for placing the storage box and squeezing and closing the edge is provided on the inner wall of the bottom of the device main body;

[0007] The wrapping and hemming mechanism includes an electric hydraulic cylinder. The electric hydraulic cylinder is fixedly connected to the inner wall of the top of the device main body. The bottom of the piston rod of the electric hydraulic cylinder is fixedly connected to a limit plate. Below the limit plate is an upper mold. Four corners of the bottom of the upper mold are fixedly connected with mounting blocks. The same rotating shaft is rotatably connected between two corresponding mounting blocks through bearings. A hemming block for hemming is fixedly connected to the circumferential outer wall of the rotating shaft. A plurality of mounting seats are fixedly connected to the bottom of the limit plate and the tops of a plurality of hemming blocks. The same rotating pin is rotatably connected to the inner walls on both sides of the mounting seat. The same support rod is fixedly connected between two vertically corresponding rotating pins.

[0008] In a possible design, a plurality of first limiting rods are fixedly connected between the inner wall of the top and the inner wall of the top of the device main body, and the plurality of first limiting rods slidably penetrate through the limit plate.

[0009] In a possible design, an annular receiving groove is formed in the inner wall of the upper mold, and a plurality of heating tubes for heating the skin are arranged in the receiving groove.

[0010] In a possible design, the support and extrusion mechanism includes a lower mold, the lower mold is fixedly connected to the bottom inner wall of the equipment main body, a plurality of sliding grooves are formed in the top of the lower mold, a second limiting rod is slidably connected in the sliding grooves, and the tops of the plurality of second limiting rods are fixedly connected to the same support plate.

[0011] In a possible design, a reset mechanism for resetting the equipment is provided between the upper mold and the limiting plate and between the support plate and the lower mold.

[0012] In a possible design, the reset mechanism includes an outer sleeve, a slider is slidably connected in the outer sleeve, the tops of the two outer sleeves are respectively fixedly connected to the bottoms of the limiting plate and the support plate, the bottoms of the two sliders are respectively fixedly connected to the tops of the upper mold and the lower mold, a first limiting protrusion integrally formed with the outer sleeve is arranged at the bottom of the circumferential inner wall of the outer sleeve, a second limiting protrusion integrally formed with the slider is arranged at the top of the circumferential outer wall of the slider, and the reset mechanism further includes a reset spring. The tops and bottoms of the two reset springs are respectively fixedly connected between the limiting plate and the upper mold and between the support plate and the lower mold.

[0013] In this application, when people need to cover the skin of a storage box, first, the storage box to be covered is inverted and buckled on the support plate, then the pretreated skin to be covered is aligned and placed at the bottom of the storage box, then the equipment is started through the control panel, then the electric hydraulic cylinder is started, and the covering and folding mechanism is pressed down as a whole by the piston rod of the electric hydraulic cylinder. The folding block will cover the skin on the surface of the storage box during the continuous pressing process. During this process, the heating tubes on the inner wall of the mounting block will heat the skin, making the skin fit more tightly on the surface of the storage box. When the storage box contacts the top inner wall of the upper mold, both reset mechanisms are compressed inward. The folding block will rotate along the rotating shaft under the push of the support rod and the pull of the mounting block, thereby realizing the folding of the edge of the skin. Then the electric hydraulic cylinder continues to press down, and the folded skin will be folded inward under the extrusion of the lower mold. Then wait for a certain time for the skin to be shaped. Then the piston rod of the electric hydraulic cylinder contracts, and the equipment resets under the elastic force of the reset spring. Then the storage box can be taken away.

[0017] In the present utility model, through the precise control of the electric hydraulic cylinder, the rapid and uniform wrapping of the skin material is realized, and the edge is finely folded by the folding edge block. This process not only improves the production efficiency, but also significantly improves the flatness and sealing performance of the edge, solving the problem of unsatisfactory edge treatment effect of traditional equipment.

[0024] Embodiment 1

[0025] Referring to Figures 1-4 , a wrapping and hemming extrusion device includes an equipment main body 1, which is a solid frame structure to support the internal components and bear the pressure and load during work. An electric hydraulic cylinder 5 is installed on the inner wall of the top of the equipment main body 1, and the electric hydraulic cylinder 5 is firmly fixed on the inner wall of the top by bolts or other fastening methods. The bottom of the piston rod of the electric hydraulic cylinder 5 is connected with a limiting plate 6. Below the limiting plate 6, an upper die 8 is provided. The shape of the upper die 8 is customized according to the size and shape of the storage box to ensure that the skin can be closely attached and wrapped on the storage box. The four corners of the bottom of the upper die 8 are connected with hemming blocks 11 through mounting blocks 9 and rotating shafts 10. The hemming blocks 11 are designed to be rotatable structures along with the rotating shafts 10 to realize the hemming operation during the skin wrapping process. To ensure the synchronous movement between the hemming blocks 11 and the limiting plate 6, they are connected through a mounting seat 12 and a support rod 14. The two ends of the support rod 14 are respectively rotatably connected with the mounting seat 12 through a rotating pin 13 to realize flexible relative movement;

[0026] To improve the adhesion between the skin and the storage box, an annular accommodating groove 15 is opened on the inner wall of the upper die 8, and a plurality of heating pipes 16 are arranged in the accommodating groove 15. The heating pipes 16 are controlled by a power supply and can be preheated to a set temperature before work to ensure that the skin remains soft and sticky during the wrapping process;

[0027] On the inner bottom wall of the device main body 1, the lower mold 17 is fixedly installed. A chute 18 is opened at the top of the lower mold 17. A second limiting rod 19 is slidably connected in the chute 18. A plurality of second limiting rods 19 jointly support the support plate 20.
