Description

Technical Field

[0001] The present application relates to the technical field of honeycomb panel forming, and in particular to a honeycomb panel core material forming device. Background Art

[0002] Honeycomb panels are a type of panel made of multiple layers of materials, which are characterized by light weight, high strength, good rigidity and earthquake resistance. Honeycomb panels include core materials and surface layers attached to both sides of the core materials. The name of honeycomb panels comes from the core material structure inside. The core material usually includes many hexagonal honeycomb units. The core material can be made of metal, plastic or other materials; the surface layer and the core material work together to improve the stability and load-bearing capacity of the structure.

[0003] The core material of honeycomb panels has many types, which can be honeycomb-shaped or other geometric shapes and layouts to meet different application needs and performance requirements. When making the core material, it is usually necessary to first extrude the sheet through an extruder, then punch the sheet through a stamping die, form the required shape of the structure on the sheet, and then send the sheet to the next process for processing. When punching the sheet, the sheet needs to be in a stationary state, so the punching process will take a certain amount of time, which is easy to affect work efficiency in continuous production.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses a honeycomb panel core material forming device. Figure 1 The core material in this embodiment is a double-layer structure composed of a first molding plate 7 and a second molding plate. The first molding plate 7 and the second molding plate have the same structure. Both the first molding plate 7 and the second molding plate are provided with grooves and protrusions along their width directions.

[0035] The honeycomb panel core material forming device comprises a first forming mechanism 1, a steering conveying mechanism 2 and a second forming mechanism 3. During the forming process, the first forming mechanism 1 first forms a first forming plate 7 with a concave-convex shape, and then conveys the first forming plate 7 to the steering conveying mechanism 2; the steering conveying mechanism 2 cuts the first forming plate 7 into blocks, and conveys the blocks of the first forming plate 7 along the extension direction of its own groove to the second forming mechanism 3; the second forming mechanism 3 forms a second forming plate with a concave-convex structure, and then presses the second forming plate onto the top surface of the first forming plate 7, thereby forming a double-layer core material structure.

[0036] The first forming mechanism 1 includes a first frame, a first die head 11, a first vacuum forming roller 12 and a first pulling roller 13. The height direction of the first frame is vertically arranged. The first die head 11 is fixedly connected to the first frame; the first die head 11 is connected to the output end of an extruder, and the length direction of the output end of the first die head 11 is horizontally arranged. The first vacuum forming roller 12 and the first pulling roller 13 are both rotatably arranged on the first frame, both are located at the discharge end of the first die head 11, and the axes of both are parallel to the length direction of the first die head 11.

[0037] Reference Figure 1 and Figure 2 The first forming part is fixedly connected to the outer wall of the first vacuum forming roller 12. The first forming part is a convex strip 121. The length direction of the convex strip 121 is parallel to the axis direction of the first vacuum forming roller 12. There are multiple convex strips 121, which are arranged in a circular array. The outer side of the convex strips 121 and the surface of the first vacuum forming roller 12 between two adjacent convex strips 121 are evenly spaced along the length direction of the first vacuum forming roller 12. A flow channel connected to the suction holes 6 is provided in the first vacuum forming roller 12, and the end of the flow channel is connected to the vacuum pump. Therefore, after the vacuum pump is started, under the action of the suction holes 6, the plate outside the first vacuum forming roller 12 can be closely attached to the surface of the first vacuum forming roller 12, so that a concave-convex structure is formed on the planar plate to form the first forming plate 7.

[0038] The first traction roller 13 is arranged above the first vacuum forming roller 12 at an interval, and the plate can pass between the first traction roller 13 and the first vacuum forming roller 12, so that the first vacuum forming roller 12 below can form the plate, and the first traction roller 13 above is pressed against the top surface of the plate. The rotating first traction roller 13 drives the plate and the formed first forming plate 7 to move along its own length direction.

[0039] Reference Figure 1The steering conveying mechanism 2 includes a support platform 21, a cutting assembly and a conveying assembly. The support platform 21 is arranged on one side of the first frame, and the top surface of the support platform 21 is horizontal; the cutting assembly and the conveying assembly are both arranged on the top surface of the support platform 21. The cutting assembly includes a cutter, a rotating power member and a driving member. The rotating power member is a motor, and the rotating power member is arranged above the support platform 21; the output shaft of the rotating power member is arranged horizontally, and the output shaft of the rotating power member is perpendicular to the axis of the first traction roller 13. The cutter is fixedly connected to the output shaft of the rotating power member, so that after the rotating power member is started, the cutter can be rotated in a plane in the width direction of the first forming plate 7, so that the first forming plate 7 can be cut along its own width direction. The driving member is a mechanical arm whose output end can move in two directions, and the rotating power member is fixedly connected to the output end of the driving member. The driving member can drive the rotating power member to move in the vertical direction and the width direction of the first forming plate 7, so the driving member drives the rotating power member to move to cut the first forming plate 7.

[0040] A limiting member 211 is also fixedly connected to the top surface of the support platform 21. The limiting member 211 is a long strip of profile, and the length direction of the limiting member 211 is parallel to the axial direction of the first traction roller 13; therefore, when the end of the first forming plate 7 abuts against the limiting member 211, the first forming plate 7 can stop moving, and then the first forming plate 7 can be cut to a required length.

[0041] The conveying assembly is a conveyor belt arranged on the top surface of the support platform 21, the belt surface of the conveyor belt is horizontal, and the length direction of the conveyor belt is parallel to the axis of the first traction roller 13; therefore, the conveyor belt can transport the block-shaped first forming plate 7 on the top surface to one side.

[0042] Furthermore, a first conveying roller 4 is arranged between the first vacuum forming roller 12 and the support platform 21, and the first conveying roller 4 is parallel to the first vacuum forming roller 12; the first conveying roller 4 is rotatably arranged on the first frame, and two first conveying rollers 4 are arranged in an upper and lower arrangement. A limiting strip 41 is fixedly connected to the outer wall of the first conveying roller 4 located at the top, and the shape of the limiting strip 41 is the same as the shape of the convex strip 121; the limiting strip 41 is arranged along the axial direction of the first conveying roller 4, and a plurality of limiting strips 41 are arranged in a circular array. Therefore, when the first forming plate 7 passes between the two first conveying rollers 4, the limiting strip 41 on the first conveying roller 4 located at the top can fit with the groove on the first forming plate 7, so that the first conveying roller 4 and the first forming plate 7 fit more closely, which helps to enhance the conveying effect of the first forming plate 7.

[0043] The second forming mechanism 3 includes a second frame, a forming assembly 31, a second vacuum forming roller 32 and an abutting roller 33. The second frame is arranged on one side of the support platform 21, and the second frame is arranged along the axial direction of the first traction roller 13. The forming assembly 31 is arranged on the second frame, and is used to form a second forming plate with the same structure as the first forming plate 7. The second vacuum forming roller 32 and the abutting roller 33 are both parallel to the length direction of the first forming plate 7, and the second vacuum forming roller 32 and the abutting roller 33 are both rotatably arranged on the second frame; the abutting roller 33 is arranged below the second vacuum forming roller 32. When the first forming plate 7 and the second forming plate pass between the second vacuum forming roller 32 and the abutting roller 33, the abutting roller 33 can press the two forming plates tightly, so that the two forming plates are better pressed together, thereby forming a double-layer core material structure.

[0044] The forming assembly 31 includes a second die head 311 and a second traction roller 312. The second die head 311 is fixedly connected to the second frame, and the second die head 311 is connected to the output end of an extruder, and the output end of the second die head 311 is tilted downward, and the output end of the second die head 311 is toward the side close to the support platform 21; the length direction of the output end of the second die head 311 is parallel to the axis of the second vacuum forming roller 32. The second vacuum forming roller 32 and the second traction roller 312 are both arranged at the discharge end of the second die head 311, and the second traction roller 312 is arranged at an interval obliquely above the second vacuum forming roller 32, and the sheet output from the second die head 311 can pass through the gap between the second traction roller 312 and the second vacuum forming roller 32, so that the second vacuum forming roller 32 forms the sheet.

[0045] Reference Figure 1 and Figure 3 , a second forming part is provided on the outer wall of the second vacuum forming roller 32, and the second forming part is a convex ring 321 coaxially fixedly connected to the outer wall of the second vacuum forming roller 32; there are multiple convex rings 321, and they are evenly spaced and arranged along the axial direction of the second vacuum forming roller 32; the cross section of the convex ring 321 is the same as the cross section of the convex strip 121. Suction holes 6 are provided on the outer wall of the convex ring 321 and on the surface of the second vacuum forming roller 32 between two adjacent convex rings 321, and a flow channel connected to the suction hole 6 is provided inside the second vacuum forming roller 32, and the flow channel is connected to the vacuum pump. Therefore, after the vacuum pump is started, under the action of the suction hole 6, the sheet output by the second die head 311 can be closely attached to the surface of the second vacuum forming roller 32, so that the sheet output by the second die head 311 is processed into a second forming plate.

[0046] The second frame is also provided with a second conveying roller 5 which is rotatably disposed between the support platform 21 and the second traction roller 312. The second conveying roller 5 is parallel to the second traction roller 312, and multiple groups of second conveying rollers 5 are provided, each group including two rollers arranged vertically. The conveying belt can convey the block-shaped first forming plate 7 to between the two second conveying rollers 5 arranged vertically, and then the second conveying roller 5 conveys the first forming plate 7 to the abutting roller 33, so as to press the first forming plate 7 and the second forming plate together.

[0047] The block-shaped first forming plate 7 conveyed by the second conveying roller 5 is located in the lower layer, and the second forming plate conveyed by the second traction roller 312 is located in the upper layer. The upper and lower forming plates pass between the second vacuum forming roller 32 and the abutting roller 33 to form a double-layer core material structure, and then move to the next process.

[0048] The sheet material is a material impregnated with resin. After the sheet is extruded by the extruder and output through the second die head 311, the temperature of the sheet is relatively high and it is easy to deform. After the sheet is processed into a second molded plate by the second vacuum forming roller 32, the first molded plate 7 and the second molded plate are adhered to each other under the action of the abutting roller 33 and the second vacuum forming roller 32. At this time, the two can be hot-melt connected, thereby fixing the two to form a stable double-layer core material structure.

[0049] In this embodiment, driving members for driving each roller to rotate are disposed on both the first frame and the second frame.

[0050] The implementation principle of a honeycomb panel core material forming device of the embodiment of the present application is as follows: after the first die head 11 outputs the plate, the plate enters between the first traction roller 13 and the first vacuum forming roller 12. Under the vacuuming action of the first vacuum forming roller 12, the plate adheres to the surface of the convex strip 121, thereby processing the plate into a first formed plate 7. Then the first traction roller 13 drives the first formed plate 7 to move to the first conveying roller 4, and the first conveying roller 4 then conveys the first formed plate 7 to the top surface of the conveyor belt on the top of the support table 21. When one end of the first formed plate 7 abuts against the limiter 211, the first traction roller 13 and the first conveying roller 4 stop rotating, so that the first formed plate 7 stops moving; at this time, the driving component drives the rotating cutter to move along the width direction of the first formed plate 7, thereby cutting off the end of the first formed plate 7 to form a block-shaped first formed plate 7. Then the conveyor belt drives the block-shaped first formed plate 7 to move to the second conveying roller 5, and the second conveying roller 5 drives the first formed plate 7 to move to the contact roller 33.

[0051] While the second conveying roller 5 is working, the second forming mechanism 3 is also in working state. The second vacuum forming roller 32 forms the plate output by the second die head 311 to process the plate into a second formed plate, and conveys the second formed plate to the abutting roller 33 through the second traction roller 312 .

[0052] The first forming plate 7 conveyed by the second conveying roller 5 is located at the bottom, and the second forming plate conveyed by the second traction roller 312 is located at the top. The upper and lower forming plates pass between the second vacuum forming roller 32 and the abutting roller 33. The abutting roller 33 is pressed against the bottom of the first forming plate 7, thereby pressing the first forming plate 7 and the second forming plate to form a double-layer core material structure; then the core material structure is conveyed to the next process.

[0053] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
