Description

Technical Field

[0001] The invention relates to the technical field of preparation of highly flame-retardant foamed silicone strips, and in particular to a method for preparing highly flame-retardant ceramic foamed silicone strips. Background Art

[0002] This high-stress silicone foam material features low density and excellent compression set resistance. Compared to traditional carbon-based foam materials, it offers superior high and low temperature resistance (-55-200°C) and a high flame retardancy rating of V-0. Furthermore, its excellent aging and weathering resistance makes it an ideal material for various applications, including shock absorption, cushioning, support, sound insulation, protection, insulation, and fire protection.

[0003] However, in the preparation process of the existing highly flame-retardant foamed silicone strips, the foamed silicone strips need to be compounded with a sticky tape backing paper first. The tape backing paper can make the foamed silicone strips have adhesion properties and can be applied to more working conditions, especially for the field of new energy batteries. After the tape backing paper is compounded, the two ends of the foamed silicone strips need to be cut to form concave and convex parts, and then glue is applied on the side walls of the concave and convex parts, and the ends of the foamed silicone strips are connected to form a silicone ring for use. The cutting, gluing and connection of the existing foamed silicone strips are all done manually, so there is an urgent need for a preparation method that can automatically complete the gluing and connection.

[0004] In addition, manual gluing and connection of the foamed silicone strips is difficult to ensure the accuracy of the size of the foamed silicone strips, the precision of the docking, and the uniformity of the gluing during the cutting, gluing and connection processes due to the flexible characteristics of the foamed silicone strips. Summary of the Invention

[0005] In response to the above problems, the present invention provides a method for preparing highly flame-retardant ceramic foamed silicone strips. By adjusting the existing method for preparing foamed silicone strips, a method for automatically preparing foamed silicone strips that can replace manual processing is provided. After the foamed silicone strips are cut, they can be directly coated with glue, docked and connected without the need for transfer. The entire process is completed automatically, without the need for manual operation, and the processing accuracy is higher.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A method for preparing a highly flame-retardant ceramic foamed silicone strip comprises the following steps:

[0008] Step a: Positioning and installing: installing the two ends of the foamed silicone strip into the positioning groove of the cutting seat, and the two ends of the foamed silicone strip are positioned by the positioning blocks vertically arranged in the positioning groove;

[0009] Step b: cutting. The positioning block and the cutting knife located above the positioning block are lowered in sequence. The positioning block presses and fixes the two ends of the foamed silicone strip. The cutting knife passes through the positioning block and cuts the two ends of the foamed silicone strip, so that the two ends of the foamed silicone strip form a convex portion and a concave portion respectively.

[0010] Step c, outputting the waste, the carrying plate carrying the convex and concave parts in the positioning groove is recovered into the cutting seat, so that the leakage channel below the carrying plate is opened, and the waste cut from the two ends of the foamed silicone strip is output through the leakage channel;

[0011] Step d, applying glue. Simultaneously with step c, when the carrier plate is retracted, the positioning block descends to form a glue groove between the two ends of the foamed silicone strip. The glue bags on both sides of the glue groove are squeezed to spray atomized glue into the glue groove. The atomized glue is applied to the side walls of the convex portion and the concave portion.

[0012] Step e, docking, is synchronized with step d. During the glue coating process, the clamping components arranged on the two side walls of the positioning groove clamp the two ends of the foamed silicone strip and slide them close to each other. The convex part and the concave part are interlaced, so that the two ends of the foamed silicone strip are spliced ​​by glue. After the splicing is finalized, the foamed silicone strip is removed from the positioning groove to complete the processing.

[0013] As an improvement, the positioning block and the supporting plate are both driven by a lifting cylinder installed at the bottom of the cutting seat to move.

[0014] As an improvement, the positioning block includes a positioning block body and a connecting block body that are integrally connected;

[0015] The positioning block is arranged in a square shape;

[0016] The connecting blocks are symmetrically arranged on both sides of the positioning block, and a glue outlet hole is opened on the connecting blocks.

[0017] As an improvement, the bearing plate includes a plate body and a tooth portion that are integrally connected;

[0018] The plate body is arranged to move horizontally, and the plate body is arranged to be flush with the bottom of the positioning groove;

[0019] The tooth portion is arranged in the cutting seat, and the tooth portion slides synchronously with the plate body. A corresponding gear is arranged above the tooth portion, and a lifting rack is arranged between the tooth portions. The rack drives the plate body to slide horizontally through the cooperation of the gear and the tooth portion, and the rack is installed and connected to the lifting cylinder.

[0020] As an improvement, the positioning block and the cutting knife are driven to rise and fall synchronously by a downward pressure cylinder, and a buffer spring is provided between the positioning block and the cutting knife. After the positioning block presses down the foamed silicone strip, the cutting knife compresses the buffer spring and descends to cut the foamed silicone strip.

[0021] As an improvement, the positioning pressing block includes an integrally arranged insert, a pressing block and a knife hole;

[0022] The insert is in a square shape and is used to embed and install the positioning pressing block;

[0023] The pressing blocks extend downward from the insert blocks, and a groove for accommodating the positioning blocks is provided between the pressing blocks;

[0024] The knife holes penetrate the insert block and the pressing block, and are arranged in a herringbone shape.

[0025] As an improvement, the cutting knife includes a panel and a cutting knife column;

[0026] The panel is in the form of a flat plate and is used for embedding and installing the cutting knife;

[0027] The cutting blade column is provided in the form of a hollow square column and is installed on the panel in a herringbone shape.

[0028] As an improvement, an exhaust groove is provided on the side wall of the cutting blade column, and an elastic floating spring plate is provided in the cavity of the cutting blade column.

[0029] As an improvement, the glue bag is connected to an external glue supply box through a pipe. The glue bag is telescopically squeezed to output glue, and a push head for squeezing is provided on the outside of the glue bag.

[0030] As an improvement, the clamping assembly includes a pushing cylinder, a moving block, a clamping bar, a driving block, a driving spring and a guide rod unit;

[0031] The pushing cylinder drives the moving block to slide along the positioning groove;

[0032] The moving block is arranged in a cross shape, and the moving block is placed in the positioning groove, and an extrusion push block is connected and arranged on both sides of the moving block. The extrusion push block moves synchronously with the moving block, and an oblique guide groove is provided on the extrusion push block, and the oblique guide groove is sleeved with the guide column on the push head;

[0033] The clamping strips are telescopically installed in the two side walls of the moving block, and the clamping strips are closed to clamp the foamed silicone strips;

[0034] A driving block is provided on the inner side of the moving block, and a driving spring is provided between the driving block and the moving block so as to abut against each other. The driving spring drives the moving block to move and push the clamping strip out of the moving block.

[0035] The guide rod unit is arranged on the other side of the moving block opposite to the pushing cylinder, and the guide rod unit is used for slidingly guiding the moving block.

[0036] The beneficial effects of the present invention are:

[0037] (1) The present invention adjusts the existing method for preparing foamed silicone strips to provide an automated method for preparing foamed silicone strips that can replace manual processing, so that after the foamed silicone strips are cut, they can be directly coated with glue, docked and connected without the need for transfer. The entire process is completed automatically without manual operation, and the processing accuracy is higher.

[0038] (2) The present invention uses the cooperation of the positioning block, the positioning groove and the positioning pressure block to wrap and fix the foamed silicone strip in all directions during the cutting process, so that the originally flexible foamed silicone strip is restrained and will not be misaligned during the cutting process, thereby ensuring the accuracy of the dimensions of the convex and concave parts formed after cutting, and providing a guarantee for subsequent connection and cooperation;

[0039] (3) When applying glue, the present invention utilizes the cooperation of the convex part, the concave part and the positioning groove to form a glue groove, so that the glue sprayed out can only be applied to the edges of the convex part and the concave part in the glue groove. At this time, the supporting plate shrinks, and the glue will not adhere to the bottom of the foamed silicone strip. Instead, the excess atomized glue will be discharged outward through the leakage channel, ensuring that the foamed silicone strip will not adhere to the positioning groove during the subsequent docking connection process.

[0040] (4) When docking, the present invention clamps and moves the foamed silicone strips together through the clamping assembly, so that the concave and convex parts are interlaced, and then adhered by glue. The entire connection process is fully automatic and does not require manual operation, which greatly ensures the accuracy of the connection.

[0041] In summary, the present invention has the advantages of high degree of automation, high processing precision, high stability, etc., and is particularly suitable for the technical field of preparation of highly flame-retardant foamed silicone strips. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0061] Example 1:

[0062] like Figures 1 to 8 As shown, a method for preparing a highly flame-retardant ceramic foamed silicone strip comprises the following steps:

[0063] Step a, positioning and mounting, mounting the two ends of the foamed silicone strip 1 into the positioning groove 21 of the cutting seat 2, and positioning the two ends of the foamed silicone strip 1 by means of the positioning blocks 22 vertically arranged in the positioning groove 21 for abutment and positioning;

[0064] Step b, cutting, the positioning block 3 and the cutting knife 4 located above the positioning block 22 are lowered in sequence, the positioning block 3 presses and fixes the two ends of the foamed silicone strip 1, and the cutting knife 4 passes through the positioning block 3 and cuts the two ends of the foamed silicone strip 1, so that the two ends of the foamed silicone strip 1 form a convex portion 11 and a concave portion 12 respectively;

[0065] Step c, outputting the waste, the carrying plate 23 in the positioning groove 21 that carries the convex portion 11 and the concave portion 12 is recovered into the cutting seat 2, so that the leakage channel 24 below the carrying plate 23 is opened, and the waste cut from the two ends of the foamed silicone strip 1 is output through the leakage channel;

[0066] Step d, applying glue. Simultaneously with step c, when the carrier plate 23 is retracted, the positioning block 22 descends, so that a glue groove 25 is formed between the two ends of the foamed silicone strip 1. The glue bags 26 located on both sides of the glue groove 25 are squeezed, and atomized glue is sprayed into the glue groove 25. The atomized glue is applied to the side walls of the convex portion 11 and the concave portion 12;

[0067] Step e, docking, is synchronized with step d. During the glue coating process, the clamping components 5 arranged on the two side walls of the positioning groove 21 clamp the two ends of the foamed silicone strip 1 and slide them close to each other. The convex portion 11 and the concave portion 12 are interlaced, so that the two ends of the foamed silicone strip 1 are spliced ​​by glue. After the splicing is finalized, the foamed silicone strip 1 is removed from the positioning groove 21 to complete the processing.

[0068] It should be noted that the foamed silicone strip in this application is a square frame with open ends. After the tape backing paper is pasted, the two ends of the foamed silicone strip need to be cut to form convex and concave parts at both ends and then interlaced and connected to form a complete circle of closed foamed silicone strip.

[0069] It should be further explained that due to the flexibility of the foam silicone strips themselves, during the manual cutting, glue coating, docking and connection process, due to the problem of force, it is easy to cause cutting misalignment, connection deformation and other problems at the connection position of the foam silicone strips. In order to effectively ensure the connection stability of the foam silicone strips, this application directly adopts an automatic connection method instead of manual connection.

[0070] Specifically, the bottom of the cutting seat 2 is suspended by the bottom bracket 101, and the positioning block 3 and the cutting knife 4 are respectively installed through the mounting plate 300, and then the mounting plate 300 is guided by the guide rod 302, and the guide rod 302 is vertically installed on the cutting seat 2. When installing, the two ends of the foamed silicone strip 1 are first limited and blocked by the positioning block 22, and then the positioning block 3 above is pressed down to fix the two ends of the foamed silicone strip 1 that need to be cut. It should be emphasized here that due to the flexibility of the foamed silicone strip 1, when the positioning block 3 is pressed down, the positioning block 3 will press the foamed silicone strip 1 downward for a distance, so that the foamed silicone strip 1 is squeezed, and thus it will not be deformed during cutting.

[0071] After the cutter 4 passes through the positioning pressing block 3 to cut the foamed silicone strip 1, a convex portion 11 and a concave portion 12 are formed at the two ends of the foamed silicone strip 1, respectively. The convex portion 11 and the concave portion 12 can just fit together. Even after the cutter 4 completes the cutting, the cutter 4 and the positioning pressing block 3 are reset, and then the glue is applied and connected. The recovery performance of the foamed silicone strip 1 makes the squeezed part of the foamed silicone strip 1 recover again, but the recovery ratio of the convex portion 11 and the concave portion 12 is equal, so the two ends of the foamed silicone strip 1 after recovery can still be accurately docked.

[0072] Afterwards, the waste output process, glue coating process and docking process are all carried out simultaneously. First, the carrying plate 23 needs to be recovered into the cutting seat 2. During the recovery of the carrying plate 23, the positioning block 22 will first descend. During the descending process of the positioning block 22, the glue outlet hole 223 on the positioning block 22 will be aligned with the glue outlet of the glue bag 26. When aligned, the carrying plate 23 has been recovered in place, and the waste falls directly through the leakage channel. After the waste falls, the clamping assembly 5 will start to clamp the foamed silicone strip 1 for a long distance contact surface, so that the foamed silicone strip 1 is clamped and moved a distance to complete the docking of the convex part 11 and the concave part 12. During the docking process, the glue in the glue bag 26 will first output atomized glue to the outside through the glue outlet hole 223 to coat the contact surface of the convex part 11 and the concave part 12. The excess atomized glue will also be output to the outside through the waste channel. Then the convex part 11 and the concave part 12 are spliced ​​and connected by glue.

[0073] It is further explained that the positioning block 22 and the carrying plate 23 are both driven by a lifting cylinder 220 installed at the bottom of the cutting seat 2 to move.

[0074] The specific solution is as follows: the positioning block 22 includes a positioning block body 221 and a connecting block body 222 which are integrally connected;

[0075] The positioning block 221 is arranged in a square shape;

[0076] The connecting blocks 222 are symmetrically arranged on both sides of the positioning block 221 , and a glue outlet hole 223 is opened on the connecting block 222 .

[0077] Furthermore, the supporting plate 23 includes a plate body 231 and a tooth portion 232 that are integrally connected;

[0078] The plate 231 is arranged to move horizontally, and the plate 231 is arranged to be flush with the bottom of the positioning groove 21;

[0079] The tooth portion 232 is arranged in the cutting seat 2, and the tooth portion 232 slides synchronously with the plate body 231. A corresponding gear 233 is provided above the tooth portion 232, and a lifting rack 234 is provided between the tooth portions 232. The rack 234 drives the plate body 231 to slide horizontally through the cooperation of the gear 233 and the tooth portion 232. The rack 234 is installed and connected to the lifting cylinder 220.

[0080] During operation, the positioning block 22 is first driven downward by the lifting cylinder 220. During the downward movement of the positioning block 22, the rack 234 moves downward synchronously. During the downward movement of the rack 234, the rack 234 cooperates with the gear 233, and the gear 233 rotates. Through cooperation with the tooth portion 232, the supporting plate 231 is recovered and retracted into the cutting seat 2.

[0081] Example 2:

[0082] like Figures 4 to 12 As shown, the differences of Example 2 of the present invention are described with reference to Example 1:

[0083] The positioning block 3 and the cutting knife 4 are driven to rise and fall synchronously by the downward pressure cylinder 30, and a buffer spring 301 is provided between the positioning block 3 and the cutting knife 4. After the positioning block 3 presses down the foamed silicone strip 1, the cutting knife 4 compresses the buffer spring 301 and descends to cut the foamed silicone strip 1.

[0084] Furthermore, the positioning pressing block 3 includes an integrally arranged insert 31, a pressing block 32 and a knife hole 33;

[0085] The insert 31 is square and is used to embed and install the positioning block 3;

[0086] The pressing block 32 extends downward from the insert block 31 , and a groove 321 for accommodating the positioning block 22 is provided between the pressing blocks 32 ;

[0087] The knife holes 33 are provided through the insert block 31 and the pressing block 32 , and the knife holes 33 are arranged in a herringbone shape.

[0088] Furthermore, the cutting knife 4 includes a panel 41 and a cutting knife column 42;

[0089] The inlay plate 41 is a flat plate, and is used to embed and install the cutting knife 4;

[0090] The cutting blade column 42 is provided as a hollow square column and is installed on the panel 41 in a herringbone shape.

[0091] In addition, an exhaust groove 421 is formed on the side wall of the cutting blade column 42 , and an elastically floating spring plate 422 is provided in the cavity of the cutting blade column 42 .

[0092] It should be noted that when the downward pressure cylinder 30 drives the positioning pressure block 3 and the cutting knife 4 to move downward, the positioning pressure block 3 will first contact the foamed silicone strip 1, and then the cutting knife 4 continues to press down, and the buffer spring 301 between the cutting knife 4 and the positioning pressure block 3 is compressed, and the cutting knife 4 will pass through the pressure block 32 through the knife hole 33 to cut the foamed silicone strip 1.

[0093] It is further explained that when the cutting column 42 cuts the foamed silicone strip 1, the waste material cut off from the foamed silicone strip 1 will be ejected by the elastic plate 422 to prevent the waste material from being inserted into the cutting column 42 and to prevent the interior of the cutting column 42 from being blocked by the waste material.

[0094] Example 3

[0095] like Figures 13 to 16 As shown, the differences of Example 3 of the present invention are described with reference to Examples 1-2:

[0096] The glue bag 26 is connected to an external glue supply box through a pipeline. The glue bag 26 is extended and squeezed to output glue, and a pusher head 261 for squeezing is provided on the outside of the glue bag 26.

[0097] Furthermore, the clamping assembly 5 includes a pushing cylinder 51, a moving block 52, a clamping bar 53, a driving block 54, a driving spring 55 and a guide rod unit 56;

[0098] The pushing cylinder 51 drives the moving block 52 to slide along the positioning groove 21;

[0099] The moving block 52 is arranged in a "F" shape and is placed in the positioning groove 21. Extrusion push blocks 521 are provided on both sides of the moving block 52. The extrusion push blocks 521 move synchronously with the moving block 52. The extrusion push blocks 521 are provided with oblique guide grooves 522, which fit with the guide posts 262 on the push head 261.

[0100] The clamping strips 53 are telescopically installed in the two side walls of the moving block 52, and the clamping strips 53 are closed to clamp the foamed silicone strip 1;

[0101] A driving block 54 is provided inside the moving block 52 , and a driving spring 55 is provided between the driving block 54 and the moving block 52 to abut against each other. The driving spring 55 drives the moving block 52 to move, thereby pushing the clamping bar 53 out of the moving block 52 .

[0102] The guide rod unit 56 is provided on the other side of the moving block 52 opposite to the pushing cylinder 51 , and the guide rod unit 56 is used to guide the moving block 52 for sliding.

[0103] It should be noted that when the clamping assembly 5 is working, the moving block 52 is first moved by the pushing cylinder 51. When the moving block 52 initially moves, the end of the driving block 54 passing through the moving block 52 will lose contact with the cutting seat 2, and the driving spring 55 will push the driving block 54 to move. The ramp block set on the driving block 52 and the ramp block set on the moving block 52 will cooperate with each other, so that the moving block 52 extends from the driving block 54, and the moving blocks 52 on both sides will cooperate with each other to complete the clamping of the foamed silicone strip 1. After that, as the pushing cylinder 51 pushes, the convex part 11 and the concave part 12 of the foamed silicone strip 1 will intersperse with each other to complete the docking.

[0104] It is further explained that when the pushing cylinder 51 pushes, the extrusion pushing block 521 that moves synchronously with the moving block 52 will drive the pushing head 261 to move, and the pushing head 261 squeezes the glue bag 26, so that the glue in the glue bag 26 is sprayed out and coated on the side walls of the convex part 11 and the concave part 12. It should be emphasized here that the glue will be sprayed out in an atomized state, and each time the glue bag 26 sprays out glue, it can be replenished through the external glue storage box.

[0105] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
