Description

Technical Field

[0001] The present invention relates to the technical field of automobile floor mat production, in particular to a three-proof automobile floor mat based on a basalt fiber-ethylene propylene diene monomer rubber composite structure and a sewing process and application thereof. Background Art

[0002] Triple-proof car floor mats are functional interiors designed specifically for cars. They achieve three core properties: waterproof, dustproof, and anti-slip. They are mostly made of TPE, PVC, or environmentally friendly blister materials. TPE is the mainstream due to its high elasticity, wear resistance, and odor-free properties, while PVC improves its waterproofness through density modification.

[0003] Patent application number CN202410580889.9 discloses a moisture-proof and antibacterial car floor mat and a preparation method thereof. The car floor mat includes a non-woven fabric base, an antifouling and antibacterial TPE foam layer and a TPE leather layer. The antifouling and antibacterial TPE foam layer is located between the non-woven fabric base and the TPE leather layer. The TPE leather layer is provided with a number of quick-drying holes, which are connected to the antifouling and antibacterial TPE foam layer. The present invention obtains antifouling, antibacterial and moisture-proof car floor mats by adjusting the structure of the floor mat and introducing antifouling and antibacterial polyols.

[0004] Traditional car floor mats are usually made of a single material or a simple composite structure, with poor waterproof, wear-resistant and anti-slip properties. During the sewing process, due to the lack of stickiness and smooth surface of the edges of similar materials such as EPDM rubber, problems such as feeding difficulties, stitch skipping, and thread breakage are prone to occur, resulting in low production efficiency and unstable product quality. In addition, traditional sewing processes make it difficult to effectively seal pinholes, allowing moisture to easily penetrate into the interior of the floor mat, reducing the waterproof performance and service life of the floor mat.

[0005] In view of this, we propose a triple-proof car floor mat based on basalt fiber-EPDM rubber composite structure and its sewing process and application. Summary of the Invention

[0006] The purpose of the present invention is to provide a triple-proof car floor mat based on a basalt fiber-EPDM rubber composite structure and its sewing process and application. By adding a processing device to the needle and thread sewing area of ​​a sewing machine, the grinding disc of the grinding part is driven by the power of the motor to pre-treat the edge of the waterproof treading layer during the rotation process, so as to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: The sewing process of the triple-proof car floor mat based on the basalt fiber-EPDM rubber composite structure includes the following steps: S1. The operator feeds the edge of the half-wrapped pad into the sewing machine for wrapping with wear-resistant hemming. The motor in the driving unit of the processing device and the sewing machine are started synchronously. S2. After the motor is started, its output shaft drives the rotating shaft and the transmission rod to rotate synchronously, thereby driving the transmission shaft in the grinding part to rotate; S3: After the transmission shaft rotates, the worm at its end engages with the worm wheel, driving the grinding disc connected to the inside of the worm wheel to rotate at high speed; S4. When the shaft rotates, the upper convex rod on the top of the telescopic frame continuously moves along the cam groove track, driving the telescopic frame and the grinding disc inside it to move back and forth, thereby grinding the edge of the waterproof treading layer; S5. After the edge of the waterproof treading layer is covered with the wear-resistant edging, it enters under the rubber roller of the sealing part, and a layer of waterproof rubber strip is covered on the top surface of the wear-resistant edging; S6. At the same time, the left and right movement of the telescopic frame drives the feeding part in the sealing part to move synchronously, and the waterproof glue stick is intermittently fed into the interior of the heating element to complete the replenishment of the waterproof glue above the rubber roller; The above steps use a sewing machine in conjunction with a processing device to complete the sewing process of the half-covered pad.

[0008] In the technical solution of the present invention, the fixing part includes a fixing frame fixedly connected to the sewing machine processing table by screws and a pair of outriggers symmetrically welded to the left end side wall of the fixing frame, and a sliding groove is provided on the outer wall of the outrigger.

The motor is fixedly connected to the right end side wall of the fixed frame by screws. The rotating shaft is coaxially connected to the output shaft of the motor. The size of the rod teeth is smaller than the shaft teeth and is engaged with them. The end of the transmission rod is integrally formed with a number of regularly distributed convex strips.

[0011] This setting increases the rotation speed of the transmission rod by setting shaft teeth and rod teeth of different sizes, thereby ensuring the edge grinding performance of the grinding part.

[0012] In the technical solution of the present invention, the cross-section of the horizontal plate on the top surface of the telescopic frame is L-shaped and is slidably connected to the inside of the two outriggers. An outer frame is integrally formed on the top surface of the telescopic frame and is sleeved on the outside of the rotating shaft, and the upper protruding rod is welded to the top surface of the outer frame.

[0014] The above arrangement, through the design of the upper convex rod and the cam groove, enables the grinding part to move horizontally as a whole during the edge grinding process, thereby improving the processing effect on the edge of the material.

[0015] In the technical solution of the present invention, the sealing portion further includes a limit frame for limiting the insertion interval of the waterproof rubber stick, and the heating element is clamped and fixed on the processing table of the sewing machine.

[0016] This setting improves the waterproof performance of the material by applying the waterproof colloid through a rubber roller.

[0017] In the technical solution of the present invention, the feeding part includes a docking plate clamped on the bottom surface of the telescopic frame, two levers clamped on the bottom surface of the docking plate, a connecting rod sleeved on the outside of the bottom end of the lever, a bracket arranged at the end of the connecting rod and parallel to the waterproof rubber stick, a clamping frame arranged at the end of the bracket, a slide arranged below the clamping frame, and a positioning rod clamped on the top surface of the slide.

[0019] The above arrangement utilizes the power generated when the telescopic frame moves left and right to drive the internal structure of the feeding part to move, thereby completing the transportation of the waterproof rubber sticks, the raw materials of the waterproof rubber strips, and reducing the investment in additional driving equipment.

[0020] On the other hand, the present invention provides the following technical solutions: The triple-proof car floor mat based on a basalt fiber-EPDM composite structure is made using the above-mentioned triple-proof car floor mat sewing process based on a basalt fiber-EPDM composite structure, and includes a half-wrapped pad, wherein the interior of the half-wrapped pad is a fiber base material layer made of basalt fiber, a waterproof treading layer wrapped around the outside of the fiber base material layer and produced from EPDM as raw material, a wear-resistant edging sewn outside the edge of the waterproof treading layer by a sewing machine, a waterproof rubber strip adhered to the top surface of the wear-resistant edging, and an anti-slip adsorption layer adhered to the bottom surface of the waterproof treading layer.

DETAILED DESCRIPTION

[0026] The following will provide a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] See also Figures 1-10 As shown, this embodiment provides a technical solution: The sewing process of the triple-proof car floor mat based on the basalt fiber-EPDM rubber composite structure includes the following steps: S1. The operator feeds the edge of the half-wrapped pad 300 into the sewing machine 100 to perform the covering operation of the wear-resistant hemming 320. The motor 221 in the driving unit 220 of the processing device 200 is started synchronously with the sewing machine 100. S2. After the motor 221 is started, its output shaft drives the rotating shaft 223 and the transmission rod 225 to rotate synchronously, thereby driving the transmission shaft 233 in the grinding part 230 to rotate; S3: After the transmission shaft 233 rotates, the worm 234 at its end engages with the worm wheel 235, driving the grinding disc 236 engaged in the worm wheel 235 to rotate at high speed; S4. When the rotating shaft 223 rotates, the upper protruding rod 232 on the top of the telescopic frame 231 continuously moves along the track of the cam groove 2230, thereby driving the telescopic frame 231 and the grinding disc 236 inside it to move back and forth, thereby grinding the edge of the waterproof treading layer 310; S5, after the edge of the waterproof treading layer 310 is covered with the wear-resistant edging 320, it enters under the rubber roller 242 of the sealing part 240, and a layer of waterproof rubber strip 330 is covered on the top surface of the wear-resistant edging 320; S6. At the same time, the left and right movement of the telescopic frame 231 drives the feeding portion 245 in the sealing portion 240 to move synchronously, and the waterproof glue stick 243 is intermittently fed into the interior of the heating element 241 to complete the replenishment of the waterproof glue above the glue roller 242; The above steps use the sewing machine 100 in conjunction with the processing device 200 to complete the sewing process of the half pad 300. The processing device 200 includes a fixing portion 210, a driving portion 220 provided on the outer sides of both ends of the fixing portion 210, a polishing portion 230, and a sealing portion 240. See also Figure 1-Figure 3 As shown, in this embodiment, the fixing portion 210 includes a fixing frame 211 fixedly connected to the processing table of the sewing machine 100 by screws and a pair of outriggers 212 symmetrically welded to the left end side wall of the fixing frame 211, and a slide groove 2120 is provided on the outer wall of the outrigger 212.

[0028] Furthermore, the fixed frame 211 is used to provide a placement platform for the results in the driving section 220, while the outrigger 212 is used to limit the movement range of the internal structure of the polishing section 230. This arrangement enables the polishing section 230 and the sealing section 240 to perform edging and sealing operations on both sides near the sewing area.

[0029] See also Figure 2-Figure 4 As shown, in this embodiment, the driving portion 220 includes a motor 221 and a rotating shaft 223 and a transmission rod 225 driven by the motor 221 , and a cam groove 2230 is formed at the end of the rotating shaft 223 .

[0030] Specifically, the driving part 220 also includes shaft teeth 222 clamped on the outer wall of the rotating shaft 223 and rod teeth 224 clamped on the outer wall of the transmission rod 225. The motor 221 is fixedly connected to the right end side wall of the fixed frame 211 by screws. The rotating shaft 223 is coaxially connected to the output shaft of the motor 221. The rod teeth 224 are smaller than the shaft teeth 222 and mesh with them. The end of the transmission rod 225 is integrally formed with a number of regularly distributed convex strips.

[0031] Furthermore, after the motor 221 is started, it drives the rotating shaft 223 to rotate, and through the engagement of the shaft teeth 222 and the rod teeth 224, the transmission rod 225 can also be driven to rotate. This setting increases the rotation speed of the transmission rod 225 by setting shaft teeth 222 and rod teeth 224 of different sizes, thereby ensuring the edge grinding performance of the grinding part 230.

[0032] See also Figure 2-Figure 6 As shown, in this embodiment, the grinding part 230 includes a telescopic frame 231, an upper protrusion 232 arranged on the top surface of the telescopic frame 231 and the top end extending into the cam groove 2230, a transmission shaft 233 inserted into the end of the transmission rod 225, a worm 234 arranged at the end of the transmission shaft 233, a worm wheel 235 engaged with the worm wheel 235, and a grinding disc 236 clamped to the inside of the worm wheel 235 through the center axis.

[0033] Specifically, the cross-section of the top surface of the telescopic frame 231 is L-shaped and is slidably connected to the inside of the two outriggers 212. The top surface of the telescopic frame 231 is integrally formed with an outer frame that is sleeved on the outside of the rotating shaft 223, and the upper protruding rod 232 is welded to the top surface of the outer frame.

[0034] Furthermore, a slot 2330 matching the size of the transmission rod 225 is opened at the right end of the transmission shaft 233, and the worm 234 is fixedly engaged with the transmission shaft 233 and rotatably connected to the inside of the square frame on the bottom surface of the telescopic frame 231, and the central axis of the top of the grinding disc 236 is engaged with the bottom surface of the telescopic frame 231.

[0035] Furthermore, the upper protruding rod 232 in the outer frame of the telescopic frame 231 can always move along the trajectory of the cam slot 2230 when the rotating shaft 223 rotates, thereby driving the telescopic frame 231 to move back and forth as a whole. At the same time, the slot 2330 set at the end of the transmission shaft 233 makes the grinding part 230 as a whole move left and right, and the transmission rod 225 is always located inside the slot 2330 without affecting the transmission of power of the transmission rod 225. The rotation of the worm 234 will engage the worm gear 235, and drive the grinding disc 236 to rotate at high speed, thereby moving left and right during the grinding process of the edge of the material, thereby improving the effect and uniformity of the grinding. This setting, through the design of the upper protruding rod 232 and the cam slot 2230, makes the grinding part 230 as a whole move left and right during the grinding process, thereby improving the processing effect of the edge of the material.

[0036] See also Figure 2-Figure 8 As shown, in this embodiment, the sealing part 240 includes a heating element 241, a rubber roller 242 rotatably connected to the bottom of the glue outlet of the heating element 241, a waterproof rubber stick 243 inserted into the feeding end of the heating element 241, and a feeding part 245 that moves with the telescopic frame 231 and continuously feeds the waterproof rubber stick 243 into the interior of the heating element 241.

[0037] Specifically, the sealing portion 240 further includes a limiting frame 244 for limiting the insertion range of the waterproof glue stick 243 , and the heating element 241 is clamped and fixed on the processing table of the sewing machine 100 .

[0038] Furthermore, the feeding part 245 includes a docking plate 2450 clamped on the bottom surface of the telescopic frame 231, two levers 2451 clamped on the bottom surface of the docking plate 2450, a connecting rod 2452 sleeved on the outside of the bottom end of the lever 2451, a bracket 2453 arranged at the end of the connecting rod 2452 and parallel to the waterproof rubber stick 243, a clamping frame 2454 arranged at the end of the bracket 2453, a slide plate 2455 arranged below the clamping frame 2454 and a positioning rod 2456 clamped on the top surface of the slide plate 2455.

[0039] Furthermore, both ends of the connecting rod 2452 are rotatably connected to the shift rod 2451 and the positioning rod 2456 respectively, the clamping frame 2454 is rotatably connected to the end of the bracket 2453, and the slide plate 2455 is slidably connected to the inside of the limiting frame 244.

[0040] Furthermore, during the horizontal movement of the telescopic frame 231 to the left and right, the docking plate 2450 in the feeding part 245 and the levers 2451 at both ends of its bottom surface will be driven to move back and forth left and right. When the lever 2451 moves to the left, the inclination angle of the connecting rod 2452 on the positioning rod 2456 will be changed first, driving the end of the bracket 2453 to contact the outer wall of the waterproof rubber stick 243. When the slide plate 2455 is subsequently driven to move to the left on the limit frame 244, the two clamping frames 2454 will clamp the waterproof rubber stick 243 and move it a short distance toward the feed port of the heating element 241. When the lever 2451 moves to the right, the end of the bracket 2453 will be moved away from the waterproof rubber stick 243 first. This setting uses the power generated by the horizontal movement of the telescopic frame 231 to drive the internal structure of the feeding part 245 to move, thereby completing the transportation of the waterproof rubber stick 243, the raw material of the waterproof rubber strip 330, and reducing the investment in additional driving equipment.

[0041] The present invention also provides a triple-proof car floor mat based on a basalt fiber-EPDM rubber composite structure, which is made using the above-mentioned triple-proof car floor mat sewing process based on a basalt fiber-EPDM rubber composite structure, and includes a half-wrapped pad 300, a fiber base material layer 340 made of basalt fiber inside the half-wrapped pad 300, a waterproof treading layer 310 wrapped around the outside of the fiber base material layer 340 and produced from EPDM rubber as raw material, a wear-resistant edging 320 sewn outside the edge of the waterproof treading layer 310 by a sewing machine 100, a waterproof rubber strip 330 adhered to the top surface of the wear-resistant edging 320, and an anti-slip adsorption layer 350 adhered to the bottom surface of the waterproof treading layer 310.

[0042] Furthermore, the waterproof treading layer 310 is produced using EPDM rubber as raw material, mainly to improve the waterproof performance of the mat body. The wear-resistant edging 320 is combined with the waterproof tape 330, and after being processed by the sewing machine 100 and the processing device 200, the waterproof effect at the edge of the mat is improved. The fiber base material layer 340 utilizes the high strength and high modulus properties of basalt fiber, and through its excellent tensile and tear resistance, it effectively resists the friction and trampling of the car mat during long-term use, thereby improving the overall durability. The three-proof car mat based on the basalt fiber-EPDM composite structure is a product developed to address the performance defects of traditional mats. Basalt fiber, as a reinforcing material, has the characteristics of high strength, high temperature resistance, acid and alkali corrosion resistance, and environmental protection and degradability. Combined with the excellent weather resistance, ozone aging resistance and waterproof performance of EPDM rubber, a composite structure with wear resistance, waterproofness and flame retardancy is formed.

[0043] In addition, in the present invention, the application of the triple-proof car floor mat based on the basalt fiber-EPDM rubber composite structure, including the above-mentioned triple-proof car floor mat based on the basalt fiber-EPDM rubber composite structure, is based on the application of the basalt fiber-EPDM rubber composite structure in automobile interior accessories.
