Description

Technical Field

[0001] This application relates to the technical field of heating plates, and in particular to a radiation heating plate. Background Art

[0002] In the industrial production of large containers, raw material plates are heated, and after the heating is completed, the raw material plates are then pressed, so as to improve the working efficiency and product quality of container pressing and forming. Currently, radiation heating plates are often used to heat raw material plates.

[0003] Currently, heating is often carried out by heating plates. The heating method of heating plates is usually overall uniform heating. Although overall uniform heating is simple and easy to implement, there is a problem of uneven heat distribution, and it cannot well meet the heating requirements of materials with different thicknesses. Especially when it comes to products with multi-layer composite materials or multi-chamber structures, in a multi-chamber structure, the chambers with deeper depths require more heat. Correspondingly, the chambers with shallower depths require less heat. A single power setting often causes overheating or poor heating linearity, and at the same time, it will also cause energy waste problems. Summary of the Invention

[0004] In order to enable the heating plate to adjust the temperature according to the requirements of different regions of the raw material, this application provides a radiation heating plate, which can save energy.

[0005] A radiation heating plate provided by this application adopts the following technical solutions: A radiation heating plate includes a housing. A reflector is installed at the bottom of the housing. A heating element is arranged at the bottom of the reflector. Installation components for installing the heating element are arranged at both ends of the heating element. The installation components are installed on the bottom surface of the reflector. The heating element is detachably connected to the installation components. A rotating component is arranged in the middle of the heating element. The other end of the rotating component is connected to the reflector. The rotating component can adjust the distance between the heating element and the reflector and the angle of the heating element. There are multiple heating elements. The multiple heating elements are arranged and distributed at the bottom of the reflector. The multiple heating elements are connected in parallel.

[0006] By adopting the above technical solution, multiple heating elements generate heat, and the heat is radiated outward in the form of infrared rays to transfer energy to the raw materials for heating. The multiple heating elements are connected in parallel, enabling independent operation among the multiple heating elements. When the raw materials need to be heated, adjustments are made according to the multi-chamber structure into which the raw materials need to be pressed. The deeper chambers require more heat, while the shallower chambers require less heat. Therefore, the multiple heating elements are partitioned according to the chambers of different depths. The heating elements located in the top area of the deeper chambers obtain a higher calorific value. Correspondingly, the heating elements located in the top area of the shallower chambers obtain a lower calorific value, so that the heating plate can adjust the temperature according to the requirements of different areas of the raw materials.

[0007] The heating element and the reflector are connected through a mounting assembly. The heating element and the mounting assembly are detachably connected, which can improve the convenience of disassembly and assembly between the heating element and the reflector. Under the action of the rotating assembly, the distance between the heating element and the reflector increases, adjusting the position of the heating element to an angle convenient for the user to wipe, thus facilitating the wiping of the surface of the reflector.

[0008] Preferably, the heating element is an "S"-shaped bent pipe.

[0009] By adopting the above technical solution, the heating element is an "S"-shaped bent pipe. Compared with the case where the heating element is a straight pipe, the "S" shape can increase the distribution density of the heating element per unit area through the bending path. Moreover, the "S"-shaped bending structure can diverge and radiate at multiple angles, enabling the infrared rays to be projected more comprehensively onto the target area, reducing the heating blind area. At the same time, the "S" shape can absorb the thermal expansion and contraction stress, reducing the risk of the heating element breaking.

[0010] Preferably, the mounting assembly includes a clamping sleeve. The clamping sleeve is arranged on one side of the reflector. The inside of the clamping sleeve has a clamping groove. One end of the clamping sleeve away from the reflector is provided with an opening, and the clamping groove communicates with the opening. One end of the heating element is inserted into the clamping groove.

[0011] By adopting the above technical solution, when the heating element needs to be installed on one side of the reflector, one end of the heating element enters from the opening close to it, and then one end of the heating element is inserted into the clamping groove. Correspondingly, when the heating element needs to be disassembled, a force is applied to the heating element away from the reflector, so that one end of the heating element is taken out from the opening, which can improve the convenience of disassembly and assembly between the heating element and the reflector.

[0012] Preferably, the mounting assembly further includes a baffle. The baffle is fixed at the outer edge of the inner wall of the clamping sleeve. The side wall of the heating element abuts against the inner wall of the baffle.

[0013] By adopting the above technical solution, under the action of the baffle, the heating element can be limited, reducing the situation where one end of the heating element passes through the outer end of the clamping sleeve. Thus, when the heating element is inserted into the clamping sleeve, it can be better positioned, enabling the heating element plug and the wire joint to be better aligned and connected.

[0014] Preferably, the rotating assembly includes a support column and a rotating column. One end of the support column is installed on one side of the reflector, one end of the rotating column is movably inserted into the support column, and the middle part of the heating element is connected to the end of the rotating column away from the support column.

[0015] By adopting the above technical solution, when it is necessary to wipe the heating element and the reflector, an outward force is applied to the rotating column. Then, the two ends of the heating element are respectively taken out from the opening, and an outward force is continuously applied to the clamping column to increase the distance between the heating element and the reflector, thus facilitating the wiping of the surface of the reflector. Rotating the rotating column can rotate and adjust the position of the heating element to an angle convenient for the user to wipe.

[0016] Preferably, the rotating assembly includes a clamping column. The end of the rotating column away from the reflector is fixed to the clamping column, and the middle part of the heating element is clamped into the clamping column.

[0017] By adopting the above technical solution, the middle part of the heating element is clamped into the clamping column, making the connection between the heating element and the rotating assembly a detachable connection, improving the disassembly and assembly convenience between the heating element and the rotating assembly. When the heating element is damaged or needs to be repaired, it is convenient to disassemble the heating element.

[0018] Preferably, a slider is fixed to the outer wall of the rotating column near the reflector end, and a sliding groove is opened on the inner wall of the support column. The sliding groove is arranged along the vertical direction of the support column, and the slider is movably inserted into one end of the sliding groove.

[0019] By adopting the above technical solution, under the action of the slider and the sliding groove, it can play a role in guiding the movement of the rotating column, making the rotating column move more stably along the vertical direction of the support column.

[0020] Preferably, a limiting groove is opened on the inner wall of the support column. The limiting groove is horizontally arranged, and one end of the limiting groove communicates with the end of the sliding groove away from the reflector.

[0021] By adopting the above technical solution, when it is necessary to wipe the heating element and the reflector, the user first holds the clamping column. When an outward force is applied to the clamping column, the two ends of the heating element are respectively taken out from the opening. After that, an outward force is continuously applied to the clamping column, so that the slider moves along the sliding groove, thereby increasing the distance between the heating element and the reflector. When the slider moves to one end of the limiting groove, the clamping column is rotated. The clamping column drives the rotating column to rotate, and the rotating column drives the slider to rotate, so that the slider enters the limiting groove and moves along the limiting groove, thereby enabling the position of the heating element to be rotated and adjusted to an angle convenient for the user to wipe. At the same time, the distance between the heating element and the reflector increases, thus facilitating the wiping of the surface of the reflector.

[0022] When the surfaces of the heating element and the reflector are wiped, the clamping column is rotated. After the slider is driven to move to one end of the sliding groove, an inward force is applied to the heating element to reduce the distance between the heating element and the reflector. Then, the two ends of the heating element are respectively inserted into the clamping sleeve to complete the installation of the heating element. Therefore, compared with the prior art where the heating element is disassembled, in this application, the distance between the heating element and the reflector is adjusted by the rotating assembly, and the angle of the heating element is adjusted to facilitate wiping, so that the situation of damage and loss caused by stacking between multiple heating elements can be reduced. At the same time, the installation efficiency between the heating element and the installation assembly can also be improved.

[0023] Under the action of the limiting groove, it can play a role in guiding the movement of the slider, and at the same time, it can also play a role in limiting. When the user wipes the heating element, the situation of the heating element shaking is reduced, further facilitating the user to wipe the heating element.

[0024] Preferably, the rotating assembly further includes a spring. The spring is arranged inside the rotating column. One end of the spring is rotatably connected to the support column, and the other end of the spring is connected to the inner wall of the rotating column.

[0025] By adopting the above technical solution, under the action of the spring, when the heating element and the installation assembly are in the installed state, the spring can provide a pulling force to the rotating column, thereby providing a pulling force to the clamping column, and further improving the connection stability between the reflector and the heating element. When the heating element is separated from the installation assembly, the slider is located in the limiting groove to adjust the angle of the heating element. When it is necessary to reset the heating element, the rotating column is rotated. When the slider moves to one end of the sliding groove, the spring can pull the slider to move along the sliding groove, reducing the time for manual probing and alignment with the sliding groove, thereby further accelerating the installation efficiency between the heating element and the installation assembly.

[0026] Preferably, a connecting block is arranged inside the support column. One end of the connecting block is movably inserted into the support column, and the connecting block is rotatably connected to the support column. One end of the spring is fixedly sleeved on the outer wall of the connecting block away from the reflector.

[0027] By adopting the above technical solution, the connecting block is rotatably connected to the support column, and one end of the spring is fixed to one end of the connecting block, so that the connection between the spring and the support column is a rotational connection. When the rotating column rotates, the spring can rotate along with it, reducing the influence of the spring on the rotation of the rotating column.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. Multiple heating elements generate heat, and the heat is radiated outward in the form of infrared rays to transfer energy to the raw material for heating. The multiple heating elements are connected in parallel, enabling them to work independently. When the raw material needs to be heated, it is adjusted according to the multi-chamber structure into which the raw material needs to be pressed. The deeper chambers require more heat, while the shallower chambers require less heat. Therefore, the multiple heating elements are partitioned according to the chambers of different depths. The heating elements located in the top area of the deeper chambers obtain a higher calorific value, and correspondingly, the heating elements located in the top area of the shallower chambers obtain a lower calorific value, so that the heating plate can adjust the temperature according to the requirements of different areas of the raw material.

[0029] 2. When it is necessary to wipe the heating element and the reflector, the user first holds the clamping column and applies an outward force to the clamping column to take out both ends of the heating element from the openings respectively. Then, continue to apply an outward force to the clamping column to make the slider move along the sliding groove, thereby increasing the distance between the heating element and the reflector. When the slider moves to one end of the limiting groove, rotate the clamping column, and the clamping column drives the rotating column to rotate. The rotating column drives the slider to rotate, causing the slider to enter the limiting groove and move along the limiting groove, so that the position of the heating element can be rotated and adjusted to an angle convenient for the user to wipe. At the same time, the distance between the heating element and the reflector increases, facilitating the wiping of the surface of the reflector.

[0030] When the surfaces of the heating element and the reflector are wiped, rotate the clamping column. After driving the slider to move to one end of the sliding groove, apply an inward force to the heating element to reduce the distance between the heating element and the reflector. Then, insert both ends of the heating element into the clamping sleeve respectively to complete the installation of the heating element. Therefore, compared with the prior art where the heating element is disassembled, the present application adjusts the distance between the heating element and the reflector through the rotating assembly and adjusts the angle of the heating element to facilitate wiping, which can reduce the damage and loss caused by the stacking of multiple heating elements, and at the same time, can also improve the installation efficiency between the heating element and the installation assembly.

Detailed implementation manners

[0038] The following Figures 1-6 will further describe the present application in detail.

[0039] The embodiment of the present application discloses a radiation heating plate.

[0040] Referring to Figure 1 and Figure 2 , a radiation heating plate includes a support frame 1. A mounting frame 2 is arranged at the top of the support frame 1. The long side of the mounting frame 2 is perpendicular to the long side of the support frame 1. Roller 21 is respectively arranged on both wide sides of the mounting frame 2. Roller 21 is rotatably connected to the bottom of the mounting frame 2 and is in rolling connection with the top of the support frame 1, so that roller 21 can roll along the long side of the support frame 1, and the mounting frame 2 can move along the long side direction of the support frame 1. The heating plate 3 is arranged at the bottom of the mounting frame 2. When the mounting frame 2 moves along the support frame 1, the heating plate 3 is driven to move along the long side direction of the support frame 1.

[0041] When the raw material is placed at the bottom of the end of the support frame 1 far from the mounting frame 2, the mounting frame 2 moves along the support frame 1 towards the end close to the raw material until the heating plate 3 is located on top of the raw material. After that, the heating plate 3 heats the raw material. After the raw material is heated, pressure is applied to the raw material to form a corresponding shape.

[0042] The heating plate 3 includes a housing 31, a reflector 32 and a heating component. The housing 31 is arranged in parallel at the bottom of the mounting bracket 2. The top of the housing 31 is fixed to the bottom of the mounting bracket 2 by bolts. The reflector 32 is installed at the bottom of the inner wall of the housing 31. The heating component is arranged at the bottom of the reflector 32. The heating component includes a heating element unit, and the heating element unit includes a plurality of heating elements 33. The plurality of heating elements 33 are evenly distributed along the wide side direction of the reflector 32. Correspondingly, there are a plurality of heating element units, and the plurality of heating element units are evenly distributed along the long side direction of the reflector 32, so that the plurality of heating elements 33 are evenly arranged and distributed at the bottom of the reflector 32.

[0043] Referring to Figure 2 , the plurality of heating elements 33 generate heat, and the heat is radiated outward in the form of infrared rays, and the energy is transferred to the raw material for heating. Under the action of the reflector 32, the reflector 32 reflects the infrared rays emitted by the heating element 33, making it concentrated in the area to be heated, reducing the loss of heat. Through reflection, the reflector 32 can redirect the heat that might have been dissipated in other directions to the target area, thereby improving the utilization efficiency of heat. The reflector 32 can reflect the infrared rays emitted by the heating element 33 to a specific direction, enhancing the radiation intensity of the target area, so that the surface of the raw material can receive more concentrated heat, thereby accelerating the heating speed.

[0044] The plurality of heating elements 33 are connected in parallel, so that the plurality of heating elements 33 can work independently. When the raw material needs to be heated, it is adjusted according to the multi-chamber structure that the raw material needs to be pressed into. The deeper chamber requires more heat, and the shallower chamber requires less heat. Therefore, the plurality of heating elements 33 are partitioned according to the chambers of different depths. The heating elements 33 located in the top area of the deeper chamber obtain a higher calorific value. Correspondingly, the heating elements 33 located in the top area of the shallower chamber obtain a lower calorific value, so that the heating plate 3 can adjust the temperature according to the requirements of different areas of the raw material.

[0045] Referring to Figure 3 , in the embodiment of the present application, the heating element 33 is an "S"-shaped bent pipe. Compared with the case where the heating element 33 is a straight pipe, the "S" shape can increase the distribution density of the heating element 33 per unit area through the bending path. Moreover, the "S"-shaped bending structure can diverge and radiate at multiple angles, making the infrared rays project more comprehensively to the target area, reducing the heating blind area. At the same time, the "S" shape can absorb the thermal expansion and contraction stress, reducing the risk of breakage of the heating element 33.

[0046] At both ends of the heating element 33, there are respectively provided mounting components 4 for its installation. The mounting components 4 are arranged on the side of the reflector 32 close to the heating element 33. The mounting components 4 include a mounting post 41 and a clamping sleeve 42. One end of the mounting post 41 is fixed on one side of the reflector 32, and one end of the clamping sleeve 42 is fixed at the end of the mounting post 41 away from the reflector 32. The inner part of the clamping sleeve 42 has a clamping groove 421, and an opening 422 is provided at the end of the clamping sleeve 42 away from the mounting post 41. The clamping groove 421 communicates with the opening 422. Correspondingly, the clamping sleeve 42 has elasticity, so that the diameter of the clamping groove 421 can be adjusted. One end of the wire passes through the mounting post 41, and the connector of the wire is located in the clamping groove 421. One end of the heating element 33 is inserted into the clamping sleeve 42, and one end of the heating element 33 is located in the clamping groove 421. The plug of the heating element 33 is electrically connected to the connector of the wire.

[0047] A baffle 43 is fixed along the inner wall edge of the clamping sleeve 42. The baffle 43 is located at the outer end of the clamping sleeve 42. The side wall of the heating element 33 abuts against the inner wall of the baffle 43. Under the action of the baffle 43, the heating element 33 can be limited, reducing the situation that one end of the heating element 33 passes through the outer end of the clamping sleeve 42. Thus, when the heating element 33 is inserted into the clamping sleeve 42, it can be better positioned, making the plug of the heating element 33 and the wire connector better aligned for connection.

[0048] Refer to Figure 3 , when it is necessary to install the heating element 33 on one side of the reflector 32, one end of the heating element 33 enters from the opening 422 close to it, and the side wall of the heating element 33 abuts against the inner wall of the baffle 43. Then, one end of the heating element 33 is inserted into the clamping groove 421. Correspondingly, when it is necessary to disassemble the heating element 33, a force is applied to the heating element 33 away from the reflector 32, so as to take out one end of the heating element 33 from the opening 422. Under the action of the mounting component 4, the disassembly and assembly convenience between the heating element 33 and the reflector 32 can be improved.

[0049] A rotating component 5 is arranged at the center of the heating element 33. The rotating component 5 includes a support post 51, a rotating post 52 and a clamping post 53. One end of the support post 51 is fixed on one side of the reflector 32. The support post 51 has a storage cavity inside. The end of the storage cavity away from the reflector 32 is through. The rotating post 52 is movably inserted into the storage cavity. The outer wall of the rotating post 52 abuts against the inner wall of the support post 51. The end of the rotating post 52 away from the reflector 32 is fixed to the clamping post 53. The middle part of the heating element 33 is clamped into the clamping post 53.

[0050] Refer to Figure 4 and Figure 5, a slider 521 is fixed to one end of the outer wall of the rotating column 52 close to the reflector 32. Correspondingly, a sliding groove 511 is formed in the inner wall of the support column 51. The sliding groove 511 is arranged along the vertical direction of the support column 51. One end of the slider 521 is movably inserted into the sliding groove, and the slider 521 can move along the long side direction of the sliding groove 511. Correspondingly, a limiting groove 512 is formed in the inner wall of the support column 51. The limiting groove 512 is horizontally arranged. One end of the limiting groove 512 communicates with one end of the sliding groove 511 away from the reflector 32. When the slider 521 moves along the sliding groove 511 to one end of the limiting groove 512, apply a force to the slider 521 at one end of the limiting groove 512 to make the slider 521 enter the limiting groove 512.

[0051] After the radiation heating plate 3 is used for a period of time, dust and stains will cover the surface of the reflector 32 or the surface of the heating element 33. The dust and stains will affect the heat transfer of the heating element 33 to the raw material. Therefore, after the radiation heating plate 3 is used for a period of time, a soft cloth needs to be used to wipe the surface of the reflector 32 and the surface of the heating element 33. However, the distance between two adjacent heating elements 33 and the distance between the heating element 33 and the reflector 32 are relatively small, making it difficult for the user to directly wipe. It is necessary to disassemble the heating element 33 before wiping. Since the number of heating elements 33 is large, after disassembling multiple heating elements 33, they need to be stacked on one side, and the multiple heating elements 33 stacked on one side are relatively easy to be lost or broken.

[0052] Refer to Figure 3 , under the action of the rotating assembly 5, when it is necessary to wipe the heating element 33 and the reflector 32, the user first holds the clamping column 53 and applies an outward force to the clamping column 53 to take out both ends of the heating element 33 from the opening 422 respectively. Then, continue to apply an outward force to the clamping column 53 to make the slider 521 move along the sliding groove 511, thereby increasing the distance between the heating element 33 and the reflector 32. When the slider 521 moves to one end of the limiting groove 512, rotate the clamping column 53. The clamping column 53 drives the rotating column 52 to rotate, and the rotating column 52 drives the slider 521 to rotate, so that the slider 521 enters the limiting groove 512 and moves along the limiting groove 512, thereby enabling the position of the heating element 33 to be rotationally adjusted to an angle convenient for the user to wipe. At the same time, the distance between the heating element 33 and the reflector 32 increases, facilitating the wiping of the surface of the reflector 32.

[0053] After the surfaces of the heating element 33 and the reflector 32 are wiped, rotate the clamping post 53. After driving the slider 521 to move to one end of the sliding groove 511, apply an inward force to the heating element 33 to reduce the distance between the heating element 33 and the reflector 32. Then, insert both ends of the heating element 33 into the clamping sleeve 42 respectively to complete the installation of the heating element 33. Therefore, compared with the prior art in which the heating element 33 is disassembled, in this application, the distance between the heating element 33 and the reflector 32 is adjusted by the rotating assembly 5, and the angle of the heating element 33 is adjusted to facilitate wiping, so as to reduce the damage and loss caused by the stacking of multiple heating elements 33. At the same time, the installation efficiency between the heating element 33 and the installation assembly 4 can also be improved.

[0054] Referring to Figure 6 , the rotating assembly 5 further includes a spring 55. A connecting block 54 is arranged in the support column 51. One end of the connecting block 54 is movably inserted into the support column 51, and the connecting block 54 is rotatably connected to the support column 51. The other end of the connecting block 54 is located in the storage cavity. One end of the spring 55 is fixedly sleeved on the outer wall of the part of the connecting block 54 located in the storage cavity, so that the spring 55 is rotatably connected to the support column 51. The spring 55 is located in the cavity of the rotating column 52, and the end of the spring 55 far from the connecting block 54 is fixed on the inner wall of the rotating column 52.

[0055] Under the action of the spring 55, when the heating element 33 and the installation assembly 4 are in the installed state, the spring 55 can provide a pulling force to the rotating column 52, so as to provide a pulling force to the clamping post 53, and further improve the connection stability between the reflector 32 and the heating element 33. When the heating element 33 is separated from the installation assembly 4, the slider 521 is located in the limiting groove 512 to adjust the angle of the heating element 33. When it is necessary to reset the heating element 33, rotate the rotating column 52. After the slider 521 moves to one end of the sliding groove 511, the spring 55 can pull the slider 521 to move along the sliding groove 511, reducing the time for manual trial alignment with the sliding groove 511, and thus further improving the installation efficiency between the heating element 33 and the installation assembly 4.

[0056] The above are all the preferred embodiments of this application. This embodiment is only an explanation of this application and does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
