Sponges with different characteristics are bonded together by flame compounding to achieve a firm compounding effect. As users' requirements for mattress functions increase, functional particles need to be laid between two layers of materials. The existing processing method requires workers to cooperate with the flame compounding machine to achieve this. During processing, workers sprinkle the functional particles on the top surface of the lower layer of material so that the upper layer of material and the upper layer of material can clamp the functional particles when they are flame compounded, which plays a role in clamping and positioning the functional particles. The use of manual material spreading not only affects production efficiency and increases production costs, but also leads to uneven distribution of functional particles, resulting in large differences in the number of functional particles in each area of ​​the composite material, resulting in reduced product quality and affecting the user experience.

DETAILED DESCRIPTION

[0025] The essential features of the present utility model are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 The flame composite device with a material spreading component shown in the figure comprises a first supply component 1, a second supply component 2, a flame composite component 3 and a finished product collection component 4. The flame composite component 3 receives the lower layer material from the first supply component 1 and the upper layer material from the second supply component 2 and conveys them to the finished product collection component 4 after flame composite. A material spreading component 5 for spreading functional particles on the top surface of the lower layer material is arranged between the first supply component 1 and the flame composite component 3, so that the lower layer material and the upper layer material are bonded and clamped by flame composite. A material spreading component 5 is arranged between the flame composite component and the first supply component 1, and the material spreading component 5 evenly spreads the functional particles on the top surface of the upper layer material from the first supply component 1, so that the upper layer material can play a role in clamping and positioning the functional particles when it is bonded with the lower layer material by flame composite, thereby processing to form a composite material clamping the functional particles, which can replace manual material spreading, save labor costs, improve processing efficiency, and improve material spreading uniformity, ensure the balanced number of functional particles in each area of ​​the composite material, ensure product quality, and improve the use experience.

[0027] In actual operation, the first supply component 1 provides the lower layer material to the scattering component 5, and the lower layer material obtains the evenly scattered functional particles at the scattering component 5 and is then transported to the flame composite component 3. The second supply component 2 transports the upper layer material to the flame composite component. The upper layer material is heated and softened by the flame sprayed by the flame exhaust 10, and then overlaps and adheres with the lower layer material to form a composite material with functional particles sandwiched therein. The processed composite material is wound and collected by the finished product collection component 4.

[0028] In actual operation, the material spreading assembly 5 includes a material spreading platform for driving the lower layer material to be transported horizontally, a material spreading roller 6 arranged above the material spreading platform, and a material storage funnel 7 (such as Figure 2 As shown in the figure, the functional particles output from the bottom of the storage hopper 7 are evenly spread on the lower material through the spreading roller 6. The spreading platform includes two supporting rollers 9 arranged in a front-to-back direction. The lower material is overlapped on the supporting rollers 9 and transported horizontally. The spreading platform not only drives the lower material forward, but also ensures that the lower material maintains a horizontal posture, ensures that the scattered functional particles can be evenly spread, and prevents deviation and slippage. The functional particles in the storage hopper 7 are scattered on the lower material through the spreading roller 6, which not only ensures that the functional particles are evenly scattered, but also effectively improves production efficiency.

[0029] In actual operation, the bottom of the storage funnel 7 is provided with an opening, and the periphery of the opening fits with the top surface of the spreading roller 6. The surface of the spreading roller 6 is provided with dense concave points, and the functional particles in the storage funnel 7 fall into the concave points, and the functional particles leave the opening with the concave points and fall on the lower layer of material. The vertical projection of the opening completely falls into the top surface of the spreading roller 6, and the periphery of the opening fits tightly with the surface of the spreading roller 6. By eliminating the gap between the two, the functional particles in the storage funnel 7 are prevented from leaking outward. When in use, the concave points on the spreading roller 6 move into the opening and provide an embedding space for the functional particles. The functional particles are embedded and hidden in the concave points and leave the storage funnel 7 after smoothly passing through the periphery of the opening. The functional particles in the concave points rotate with the spreading roller 6 and fall to the top surface of the lower layer of material by their own gravity. The number of functional particles scattered can be controlled by controlling the density of the concave points. The distribution density of the functional particles on the lower layer of material is adjusted by adjusting the relationship between the rotation speed of the spreading roller 6 and the conveying speed of the lower layer of material, thereby meeting the processing requirements.

[0030] In actual operation, the material spreading assembly 5 includes a brush roller 8 (such as Figure 3 As shown in the figure, the brush roller 8 rotates and sweeps off the functional particles adsorbed on the spreading roller 6, so that the functional particles are scattered on the lower layer of material. The spreading roller 6 rotates continuously, and the concave points on it first pass through the opening to obtain the functional particles, and then expose downward to make the functional particles fall to the top surface of the lower layer of material, and finally the brush roller 8 drives the functional particles adhering to the concave points to detach, so that the concave points can enter the opening again and obtain the functional particles, ensuring that the spreading roller 6 can continuously transport the functional particles between the storage funnel 7 and the lower layer of material.

[0031] In actual operation, the flame composite assembly 3 includes a pressure roller group and a flame row 10 (such as Figure 4 As shown in the figure, the roller group includes an upper roller 12 and a middle roller 13 arranged adjacent to each other from top to bottom. The upper material is heated by the flame ejector 10 and transferred to the surface of the middle roller 13 through the upper roller 12, and then adhered to the lower material to form a composite finished product with functional particles. The bottom surface of the upper material is first heated and melted by the flame ejector 10 and then adhered to the top surface of the lower material, which not only ensures that the upper material and the lower material are firmly adhered, but also plays a role in adhesion and positioning of the scattered functional particles, ensuring that the functional particles are always evenly dispersed.

[0032] In actual operation, the pressure roller assembly includes a lower pressure roller 14 arranged below the middle pressure roller 13 and a receiving roller 11 arranged above the upper pressure roller 12. The middle pressure roller 13 cooperates with the lower pressure roller 14 to perform secondary extrusion on the composite finished product, and the receiving roller 11 is adjacent to the upper pressure roller 12 and cooperates to receive the upper layer of material from the second supply assembly 2. During processing, first, the receiving roller 11 receives the upper layer material from the second feeding assembly and adjusts the moving angle of the upper layer material so that the bottom surface of the upper layer material can be effectively heated and softened by the flame exhaust 10; then, the upper layer material will be adhered to the lower layer material and tightly fitted with the middle pressure roller 13 under the guidance of the upper pressure roller 12, so that the upper layer material and the lower layer material are adhered to each other and fixedly bonded to form a composite material; then, the composite material will be tightly fitted with the surface of the middle pressure roller 13 under the limiting action of the lower pressure roller 14, and the lower pressure roller 14 and the middle pressure roller 13 are used to achieve secondary extrusion, so as to further improve the adhesion strength between the upper layer material and the lower layer material; finally, the processed composite material is separated from the flame composite assembly and is wound and collected by the finished product collection assembly 4.

[0033] In actual operation, the middle pressure roller 13 is arranged at the same height as the supporting roller 9, so that the lower layer of materials receives the functional particles in a horizontal posture and transfers them to the flame composite assembly 3. The top edge of the middle pressure roller 13 is arranged at the same height as the top edge of the supporting roller 9, so that the lower layer of materials receiving the functional particles can be transported from the bulk material platform to the flame composite assembly 3 in a horizontal posture, preventing the functional particles from deviating, converging or slipping during transportation, and ensuring that the functional particles are evenly dispersed before being adhered and positioned by the upper layer of materials.

[0034] In actual operation, the first supply assembly 1, the second supply assembly 2 and the finished product collection assembly 4 all include a reel portion 18 and a material storage portion (such as Figure 6As shown in the figure, the material storage part includes an upper part and a lower part which correspond vertically and are used for reciprocating winding of the fabric vertically. The material storage part adjusts the length of the stored fabric by controlling the distance between the upper part and the lower part, so that the reel part 18 can switch between the rotating state and the reel changing state. The reel part 18 is provided with a reel for winding the upper layer material, the lower layer material or the composite material, which is convenient for taking, placing and transporting. The material storage part is arranged between the reel part 18 and the flame composite component 3. The length of the fabric stored in the material storage part is adjustable. The material storage part is used to play the role of buffer storage, so that the reel part 18 can switch between the rotating state and the reel changing state. Specifically, when the roll section 18 in the first feeding assembly or the second feeding assembly needs to replace the roll, the corresponding storage section continuously supplies material to the flame composite assembly 3 by reducing the length of the stored cloth, and consumes the cloth stored in the storage section to cope with the cloth consumption during the continuous processing of the flame composite assembly, thereby providing a time window for the roll section 18 to replace the roll. After the roll replacement is completed, the roll section 18 continuously outputs cloth, providing cloth for both the flame composite assembly 3 and the storage section, so that the length of the cloth stored in the storage section is increased, in preparation for replacing the roll again. Preparation; when the roll in the finished product collection component 4 needs to be replaced, the corresponding storage section receives the composite material produced by the flame composite component 3 by increasing the length of the stored cloth, and the storage section independently receives the composite material produced by the continuous processing of the flame composite component, providing a time window for the roll section 18 to replace the roll. After the roll replacement is completed, the roll section 18 quickly receives the composite material, which effectively receives the composite material continuously produced by the flame composite component 3 and the composite material stored in the storage section, so that the length of the cloth stored in the storage section is reduced, preparing for replacing the roll again.

[0035] In actual operation, the storage sections in the first and second feeding assemblies usually store longer-sized cloths, and the storage section in the finished product collection assembly 4 usually stores shorter-sized composite materials to ensure that roll replacement will not affect the continuous operation of the flame composite assembly 3.

[0036] In actual operation, both the first feeding assembly and the second feeding assembly are provided with a high temperature clamping plate, which is arranged at the storage portion facing the corresponding reel portion 18. The high temperature clamping plate can perform hot melt bonding on the independent ends of the cloth after the reel is replaced, so that the flame composite assembly 3 can continue to operate. The finished product collection assembly 4 is provided with a cutting piece to cut the continuously produced composite material, so that the finished product collection assembly 4 can perform the reel replacement operation.

[0037] In actual operation, the upper member includes a plurality of feed rollers 15 arranged in a forward and backward direction and guiding the cloth to turn, and the lower member includes a plurality of feed rollers 16 arranged in a forward and backward direction and guiding the cloth to turn. The cloth reciprocates vertically and winds around the corresponding feed rollers 15 and feed rollers 16 in sequence (such as Figure 5As shown). The vertical projection of the upper material roller 15 and the vertical projection of the lower material roller 16 are alternately staggered so that there is a movable gap between each vertical section formed by the vertical reciprocating winding of the cloth. By setting a plurality of upper material rollers 15 and lower material rollers 16, the number of reciprocating bending times of the cloth is increased, thereby increasing the cloth storage length in the effective space, and reserving a longer operation time for changing the roll. When the distance between the upper and lower parts increases, the distance between the corresponding upper material roller 15 and lower material roller 16 of the cloth increases, so that the length of the cloth stored in the storage section increases. Conversely, when the distance between the upper and lower parts decreases, the distance between the corresponding upper material roller 15 and lower material roller 16 of the cloth decreases, so that the length of the cloth stored in the storage section decreases.

[0038] In actual operation, the distance between the upper part and the lower part is adjusted by the cylinder 17, the loading roller 15 on the upper part can be raised and lowered synchronously, and the unloading roller 16 on the lower part can be raised and lowered synchronously. By adjusting the lifting speed between the upper part and the lower part, the increase and decrease speed of the cloth length in the storage part is ensured to be consistent with the processing speed of the flame composite component 3, so as to prevent the cloth from being torn due to pulling.

[0039] In actual operation, the upper layer material and the lower layer material can be sponge, cloth, etc., which should be regarded as specific embodiments of the present invention. The functional particles can be massage particles, activated carbon particles, etc., and the corresponding functions are obtained by adding functional particles, which should be regarded as specific embodiments of the present invention.
