Description

Technical Field

[0001] The invention relates to the technical field of heat-insulating material processing, in particular to a pressing device for multi-layer heat-insulating materials. Background Art

[0002] Thermal insulation material is a material with heat insulation, thermal insulation function and other special properties. Its main feature is that the thermal conductivity is small, which can play a good role in thermal insulation in the fields of construction, industry, etc. The main function of thermal insulation material is to insulate and preserve heat, which plays a role in energy saving and consumption reduction, and can also reduce environmental pollution. With the development of science and technology, thermal insulation materials are also constantly updated, and many different types and uses have emerged. Among them, multi-layer thermal insulation materials are deeply loved by the public because of their good thermal insulation effect. In the production process of multi-layer thermal insulation materials, in order to make the connection between the multi-layer materials closer, pressing equipment is often used to press the multi-layer thermal insulation materials. Pressing; In the prior art, when pressing multi-layer thermal insulation materials, it is necessary to place the multi-layer thermal insulation materials inside the mold, and use hydraulic equipment to apply a downward force to the upper mold of the mold, thereby realizing the pressing of the multi-layer thermal insulation materials. During the pressing process, the air between the multi-layer thermal insulation materials will be discharged outward due to the application of pressure, thereby ensuring the pressing effect of the multi-layer thermal insulation materials. However, some pressing equipment directly applies pressure to the multi-layer thermal insulation materials, and the surface of the multi-layer thermal insulation materials is subjected to downward pressure at the same time. Some air located in the middle of the multi-layer thermal insulation materials cannot be discharged outward in time, resulting in incomplete exhaust effect, which affects the pressing quality of the multi-layer thermal insulation materials.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a pressing device for multi-layer thermal insulation materials, comprising a workbench and a material pushing mechanism;

An oil pipe 1 is provided between the oil inlet and the oil outlet of the hydraulic station on the left, and the oil pipe 1 is connected in series with the hydraulic telescopic rod;

[0006] The ejecting mechanism is arranged at the lower end of the lower mold. Before the pressing begins, the air between the multiple layers of thermal insulation materials is gradually discharged from the middle to the outer edge, so that the air between the multiple layers of thermal insulation materials is discharged more thoroughly, thereby improving the pressing quality of the multiple layers of thermal insulation materials.

The lower end of the outer arc surface of the hollow disk is provided with a pressure plate. The lower end of the hollow disk is an open structure, and the multi-layer insulation material is pressed together by cooperating with the lower mold.

[0008] Furthermore, the upper mold also includes hollow disk 2, hollow disk 3 and hollow disk 4. The hollow disk 2 is vertically slidably connected to the inside of the hollow disk 1, and the upper and lower ends of the hollow disk 2 are both open structures. The inside of the hollow disk 2 is vertically slidably connected to the hollow disk 3, and the upper and lower ends of the hollow disk 3 are both open structures. The inside of the hollow disk 3 is vertically slidably connected to the hollow disk 4, and the upper end of the hollow disk 4 is an open structure, which gradually applies force to the multiple layers of thermal insulation material from the middle to the outer edge to discharge the air between the multiple layers of thermal insulation material.

Hollow disk 1 and oil pipe 2 are connected in series to provide power for the extension and contraction of hollow disk 2, hollow disk 3 and hollow disk 4.

[0011] Furthermore, the vertical height of the hollow disk 2, the hollow disk 3 and the hollow disk 4 is equal to the distance from the lower surface of the hollow disk to the top wall, ensuring that the upper and lower surfaces of the hollow disk 1, the hollow disk 2, the hollow disk 3 and the hollow disk 4 are in the same plane in the contracted state.

[0012] Furthermore, the ejection mechanism includes an outer top plate, a sliding column, a middle top plate and a spring.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When in use, place the multi-layer thermal insulation material inside the lower mold, start the hydraulic station, and make the telescopic end of the hydraulic telescopic rod drive the hollow disk one to move downward. At this time, the space formed by the hollow disk one, hollow disk two, hollow disk three and hollow disk four is filled with hydraulic oil. Under the action of oil pressure, the hollow disk four, hollow disk three and hollow disk two successively contact the multi-layer thermal insulation material and exert force on it, gradually expelling the air between the multi-layer thermal insulation material from the middle to the outer edge, and then stop the hydraulic station on the right side to keep the lower surfaces of the pressing plate, hollow disk one, hollow disk two, hollow disk three and hollow disk four in the same horizontal plane. Then, as the hydraulic telescopic rod is extended, the multi-layer thermal insulation material is pressed together. Before the pressing starts, the air between the multi-layer thermal insulation material is gradually discharged from the middle to the outer edge, so that the air between the multi-layer thermal insulation material is discharged more thoroughly, thereby improving the pressing quality of the multi-layer thermal insulation material.

[0017] 2. After the pressing is completed, the hollow disk 1 moves up, and the hollow disk 2, hollow disk 3 and hollow disk 4 are used to press the middle part of the multi-layer thermal insulation material, and the electric push rod is started to overcome the elastic force of the spring, drive the outer edge top plate to move upward, and exert an upward force on the outer edge of the multi-layer thermal insulation material, so that the outer edge of the multi-layer thermal insulation material is first separated from the inner wall of the lower mold, and then as the hollow disk 2, hollow disk 3 and hollow disk 4 gradually move upward, the pressure on the middle part of the multi-layer thermal insulation material is cancelled, and the cooperation of the outer edge top plate and the middle top plate is used to push the pressed multi-layer thermal insulation material out of the lower mold, first separating the multi-layer thermal insulation material from the mold from the outer edge, making the demoulding of the multi-layer thermal insulation material more stable and quick, reducing the damage to the multi-layer thermal insulation material, and facilitating the use of the multi-layer thermal insulation material pressing machine.

[0026] See also Figure 1-6 This embodiment provides a technical solution: a pressing device for multi-layer thermal insulation materials, including a workbench 1 and a material pushing mechanism 9.

[0027] A lower mold 2 is provided on the upper surface of the workbench 1, and a bracket 3 is provided at the rear end of the upper surface of the workbench 1. A support plate 4 is provided on the upper end of the bracket 3 to provide support for the setting of the pressing parts. A hydraulic telescopic rod 5 is provided in the middle of the support plate 4, and an upper mold 6 is provided at the lower end of the telescopic end of the hydraulic telescopic rod 5. The upper mold 6 is driven up and down by the extension and contraction of the hydraulic telescopic rod 5. The multi-layer thermal insulation material is pressed together by the cooperation of the upper mold 6 and the lower mold 2. A hydraulic station 8 is provided inside the workbench 1. An oil pipe 7 is provided between the oil inlet and the oil outlet of the hydraulic station 8 on the left. The oil pipe 7 is connected in series with the hydraulic telescopic rod 5 to provide power for the operation of the hydraulic telescopic rod 5. A control unit 10 is provided on the front surface of the workbench 1 to control the start and stop of the entire device. The signal controlled end of the hydraulic station 8 is electrically connected to the signal control end of the control unit 10.

[0028] The upper mold 6 includes a hollow disk 1 61 and a pressure plate 62. The hollow disk 1 61 is arranged at the lower end of the telescopic end of the hydraulic telescopic rod 5. The lower end of the outer arc surface of the hollow disk 1 61 is provided with a pressure plate 62. The lower end of the hollow disk 1 61 is an open structure. The upper mold 6 also includes a hollow disk 2 63, a hollow disk 3 64 and a hollow disk 4 65. The hollow disk 2 63 is vertically slidably connected to the inside of the hollow disk 1 61. The upper and lower ends of the hollow disk 2 63 are both open structures. The interior of the hollow disk 2 63 is vertically slidably connected to the hollow disk 3 64. The upper and lower ends of the disk 3 64 are both open structures. The interior of the hollow disk 3 64 is vertically slidably connected to the hollow disk 4 65. The upper end of the hollow disk 4 65 is an open structure. Through the sequential contraction of the hollow disk 4 65, the hollow disk 3 64 and the hollow disk 2 63, a force is gradually applied to the multi-layer insulation material from the middle to the outer edge, so that the air between the multi-layer insulation materials is discharged more thoroughly. The upper mold 6 also includes a sealing gasket 66, which is respectively arranged on the hollow disk 1 61, the hollow disk 2 63 and the hollow disk 3 64. The bottom wall seals the hollow disk 1 61, the hollow disk 2 63, the hollow disk 3 64 and the hollow disk 4 65. The upper ends of the inner arc surfaces of the hollow disk 2 63, the hollow disk 3 64 and the hollow disk 4 65 are all tapered. Under the action of oil pressure, the tapered arc surface is used to apply a downward force to the hollow disk 2 63, the hollow disk 3 64 and the hollow disk 4 65 to improve the sealing effect. The upper mold 6 also includes an oil pipe 2 67. The oil pipe 2 67 is arranged between the oil inlet and the oil outlet of the hydraulic station 8 on the right side. The hollow disk 1 61 and the oil pipe 2 67 are connected in series to provide power for the extension and retraction of hollow disk 2 63, hollow disk 3 64 and hollow disk 4 65. The vertical height of hollow disk 2 63, hollow disk 3 64 and hollow disk 4 65 is equal to the distance from the lower surface of hollow disk 1 61 to the top wall. When hollow disk 2 63, hollow disk 3 64 and hollow disk 4 65 are in the contracted state, the lower surfaces of pressure plate 62, hollow disk 1 61, hollow disk 2 63, hollow disk 3 64 and hollow disk 4 65 are in the same horizontal plane, which facilitates the application of uniform downward pressure on the multi-layer thermal insulation material.

[0029] The ejection mechanism 9 is arranged at the lower end of the lower mold 2. The ejection mechanism 9 includes an outer top plate 91, a sliding column 92, a middle top plate 93 and a spring 94. The outer top plate 91 is vertically slidably connected to the inside of the lower mold 2. The sliding holes on the bottom wall of the outer top plate 91 are slidably connected with sliding columns 92. A middle top plate 93 is provided between the upper ends of the sliding columns 92. Springs 94 are respectively provided between the lower surface of the middle top plate 93 and the bottom wall of the outer top plate 91. The springs 94 are respectively movably sleeved on the outer arc surface of the sliding columns 92. The ejection mechanism 9 also includes an electric push rod 95. The electric push rod 95 is respectively arranged in the mounting hole at the lower end of the lower mold 2. The upper ends of the telescopic ends of the electric push rod 95 are fixedly connected to the outer top plate 91. The signal-controlled end of the electric push rod 95 is electrically connected to the signal control end of the control unit 10.

[0030] A support 11 is provided in the middle of the bottom wall of the lower mold 2. The support 11 passes through the middle of the outer top plate 91 and is installed in conjunction with the middle top plate 93. During the pressing process, the outer top plate 91 contacts the bottom wall of the lower mold 2, and the middle top plate 93 contacts the support 11. Through the cooperation between the outer top plate 91 and the middle top plate 93, support is provided for the lower end of the multi-layer thermal insulation material. After the pressing is completed, the electric push rod 95 is started, and the telescopic end of the electric push rod 95 drives the outer top plate 91 to move upward. At this time, the hollow disk 2 63, the hollow disk 3 64 and the hollow disk 4 65 press the multi-layer thermal insulation material. A downward force is applied to press the middle part of the multi-layer thermal insulation material, overcoming the elastic force of the spring 94, so that the sliding column 92 and the outer edge top plate 91 slide relative to each other, and the outer edge top plate 91 is used to apply an upward force to the outer edge of the multi-layer thermal insulation material, so that the outer edge of the multi-layer thermal insulation material is first separated from the inner wall of the lower mold 2, and then as the hollow disk 2 63, the hollow disk 3 64 and the hollow disk 4 65 gradually move upward, the pressure on the middle part of the multi-layer thermal insulation material is cancelled, and the pressed multi-layer thermal insulation material is ejected from the interior of the lower mold 2 by using the cooperation of the outer edge top plate 91 and the middle top plate 93.

[0031] The working principle of the laminating device for multi-layer thermal insulation materials provided by the present invention is as follows:

[0032] When in use, the multi-layer thermal insulation material is placed inside the lower mold 2. At this time, the outer top plate 91 contacts the bottom wall of the lower mold 2, and the middle top plate 93 contacts the support 11. The cooperation between the outer top plate 91 and the middle top plate 93 provides support for the lower end of the multi-layer thermal insulation material. Then, the hydraulic station 8 is started by the control unit 10 to provide power for the extension and retraction of the hydraulic telescopic rod 5. The telescopic end of the hydraulic telescopic rod 5 drives the hollow disk 1 61 to move downward. At this time, the space formed by the hollow disk 1 61, the hollow disk 2 63, the hollow disk 3 64 and the hollow disk 4 65 is filled with hydraulic oil. Under the action of the oil pressure, the hollow disk 2 63, the hollow disk 3 64 and the hollow disk 4 65 are When the hollow disk 1 61 moves downward to its maximum position, as the hollow disk 1 61 moves downward, when the hollow disk 4 65 contacts the multi-layer thermal insulation material, the multi-layer thermal insulation material exerts a reaction force on the hollow disk 4 65, causing the hollow disk 4 65 to move upward. At the same time, the oil pressure is used to apply a force to the surface of the multi-layer thermal insulation material to pre-press the multi-layer thermal insulation material, so that the air between the multi-layer thermal insulation material is discharged. Similarly, the hollow disk 4 65, the hollow disk 3 64 and the hollow disk 2 63 are moved upward in sequence until the hollow disk 4 65, the hollow disk 3 64 and the hollow disk 2 63 contact the top wall of the hollow disk 1 61, and the air between the multi-layer thermal insulation material is gradually discharged from the middle to the outer edge, so that the multi-layer thermal insulation material is The air between the two layers is discharged more thoroughly, and then the hydraulic station 8 on the right is stopped. The hollow disc 2 63, the hollow disc 3 64 and the hollow disc 4 65 do not apply pressure to the multi-layer thermal insulation material, and the lower surfaces of the pressing plate 62, the hollow disc 1 61, the hollow disc 2 63, the hollow disc 3 64 and the hollow disc 4 65 are kept at the same horizontal plane. Then, as the hydraulic telescopic rod 5 is extended, downward pressure is evenly applied to the multi-layer thermal insulation material to press the multi-layer thermal insulation material. After the pressing is completed, the hydraulic telescopic rod 5 contracts, driving the upper mold 6 to reset, and at the same time, the hydraulic oil is restored to the inside of the upper mold 6, so that the hollow disc 2 63, the hollow disc 3 64 and the hollow disc 4 65 apply pressure to the multi-layer thermal insulation material. The downward force is applied to press the middle part of the multi-layer thermal insulation material, and then the electric push rod 95 is started. The telescopic end of the electric push rod 95 drives the outer edge top plate 91 to move upward, overcoming the elastic force of the spring 94, so that the sliding column 92 and the outer edge top plate 91 slide relative to each other, and the outer edge top plate 91 is used to apply an upward force to the outer edge of the multi-layer thermal insulation material, so that the outer edge of the multi-layer thermal insulation material is first separated from the inner wall of the lower mold 2, and then as the hollow disk 2 63, the hollow disk 3 64 and the hollow disk 4 65 gradually move upward, the pressure on the middle part of the multi-layer thermal insulation material is cancelled, and the pressed multi-layer thermal insulation material is pushed out of the lower mold 2 by the cooperation of the outer edge top plate 91 and the middle top plate 93.
