Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric heat sealing technology, specifically to a heat sealing machine for antibacterial, biodegradable, and environmentally friendly composite nonwoven fabrics. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It possesses characteristics such as moisture resistance, breathability, flexibility, lightweight, non-flammability, easy decomposition, non-toxicity, non-irritation, antibacterial and biodegradable properties, and recyclability. To improve the tensile and tear strength of non-woven fabrics and extend their service life, two pieces are often heat-sealed together. This involves using an electric heating plate to heat-press the stacked non-woven fabrics together, binding their components to form a strong textile. However, the following problems are frequently encountered during the heat-sealing process:

[0003] A single electric heating plate heats and presses the nonwoven fabric from one side of the stacked nonwoven fabric, which makes it difficult for the temperature of the other side of the stacked nonwoven fabric to rise synchronously, which is not conducive to achieving uniform heating and pressure on the top and bottom surfaces of the nonwoven fabric.

[0004] The heat-pressed side of the non-woven fabric will absorb dust and impurities in the workshop. If the dust on the surface of the non-woven fabric is not cleaned, it will easily affect the quality of the heat-sealed fabric later.

[0005] The nonwoven fabric wound on the nonwoven fabric take-up roller cannot be guaranteed to be wound straight, resulting in wrinkles in the nonwoven fabric released from the nonwoven fabric take-up roller. If the wrinkled areas are not straightened, it will directly affect the straight heat sealing of the two nonwoven fabrics in the later stage.

[0006] Harmful gases are produced during the heat sealing process of non-woven fabrics. Most heat sealing machines do not easily absorb and collect these harmful gases during the heat sealing process, which affects the health of workers. Summary of the Invention

[0007] To overcome the aforementioned technical problems, the present invention aims to provide an antibacterial, biodegradable, and environmentally friendly composite nonwoven fabric heat sealing machine. This machine arranges two pieces of nonwoven fabric in a V-shape, then brings two heat sealing boxes close together to clamp the two pieces. Under the pressure of the heat sealing boxes, the nonwoven fabric overcomes the elastic force of the return spring on the telescopic component, dragging the fabric rollers and thus keeping the nonwoven fabric to be heat-sealed taut. A dust-collecting plate is placed against the side of the nonwoven fabric to be heat-sealed, with its mesh in contact with the nonwoven fabric. An external vacuum cleaner draws air into the suction chamber of the dust-collecting plate through its suction pipe. The airflow draws in air, which removes dust and impurities adhering to the surface of the nonwoven fabric, ensuring the nonwoven fabric is clean and tidy before hot pressing and improving the quality of the fabric after heat sealing. Two hot pressing plates heat and pressurize the top and bottom surfaces of the nonwoven fabric simultaneously, ensuring uniform heating and pressure on both surfaces and improving the effect of hot pressing. After hot pressing, an electric push rod moves the hot pressing plates away from the nonwoven fabric, and then an external air pump draws air into the exhaust pipe of the heat sealing box, causing harmful gases in the space where the nonwoven fabric is hot pressed to be drawn away and collected, preventing harmful gases from being absorbed by the staff.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A heat-sealing machine for antibacterial, biodegradable, and environmentally friendly composite nonwoven fabric includes a base plate. Two support frames are fixed to one end of the top surface of the base plate. Movable blocks are slidably engaged at the top and bottom of each support frame. A connecting shaft is detachably and rotatably inserted between two movable blocks arranged opposite each other on the two support frames. A weaving roller is fixed to the outside of the connecting shaft. Tensioning mechanisms are provided at the top and bottom of each support frame. Each tensioning mechanism includes two positioning wheels, two positioning wheels, and a movable wheel. A telescopic component is connected to the movable wheels and the support frames. A belt is connected to multiple positioning wheels and movable wheels. The base plate... Two C-shaped plates are fixed in the middle of the top surface. A bidirectional lead screw and a guide shaft are respectively installed inside the two C-shaped plates. A heat sealing box is screwed to the top and bottom of the bidirectional lead screw. A hot pressure plate is slidably connected to the open end of the heat sealing box. A guide frame is fixed in the middle of the top surface of the bottom plate. A bidirectional lead screw is rotatably connected inside the guide frame. A support assembly is screwed to both ends of the bidirectional lead screw. A positioning shaft is fixed at the top of the support assembly. A dust suction plate is rotatably connected to one end of the positioning shaft. Two columns are fixed to one end of the top surface of the bottom plate away from the support frame. Two limiting rollers are rotatably connected between the two columns.

[0010] Furthermore, the support assembly includes a support base that is screwed into the bidirectional lead screw. A rectangular blind hole is provided on the top of the support base. An electric push rod is fixed inside the rectangular blind hole. A support block is fixed at the output end of the electric push rod. The support block is inserted and fixed to the positioning shaft at the corresponding position.

[0011] Furthermore, one end of the guide frame is fixed with a motor for driving the bidirectional lead screw to rotate, and one side of the dust collection plate is fixed with a fixed seat that is rotatably sleeved with the positioning shaft at the corresponding position. A torsion spring is provided between the fixed seat and the positioning shaft.

[0012] Furthermore, the suction plate has a mesh opening on the side near the non-woven fabric, and a suction chamber communicating with the mesh opening is opened inside the suction plate. A nozzle communicating with the suction chamber is fixed at the edge of the suction plate, and a suction pipe is connected and fixed to the outside of the nozzle. The suction pipe is connected and fixed to the suction pipe of an external vacuum cleaner.

[0013] Furthermore, the outer side of the heat sealing box is connected and fixed with a second connector, and the outer side of the second connector is connected and fixed with an air extraction pipe. The air extraction pipe is connected and fixed to the air extraction end of an external air pump through a flexible hose. The inner side of the heat sealing box has two electric push rods, and the output end of the electric push rods is fixedly connected to the heat pressure plate.

[0014] Furthermore, both ends of the bidirectional lead screw are rotatably connected to the inverted plate, both ends of the guide shaft are fixedly connected to the inverted plate, and a connecting block fixedly connected to the base plate is fixed on the bottom surface of the inverted plate. A motor for driving the bidirectional lead screw to rotate is fixed inside one of the inverted plates.

[0015] Furthermore, a dual-axis motor is fixed between the top and bottom of the two support frames, wherein one of the positioning wheels is fixedly connected to the output end of the dual-axis motor, the other positioning wheel is fixedly connected to the connecting shaft, and the positioning wheel is rotatably connected to the support frame.

[0016] Furthermore, the telescopic component includes a sleeve, a sliding rod is slidably inserted inside the sleeve, the sliding rod is rotatably connected to a moving wheel, a return spring is fixed between the sleeve and the sliding rod, and both ends of the support frame are fixed with fixing seats that are respectively fixedly connected to the sleeve at the corresponding position.

[0017] The beneficial effects of this invention are:

[0018] 1. By gathering the non-woven fabric on two spinning rollers to the positions of two limiting rollers, heat sealing boxes are arranged on the outer sides of the two non-woven fabrics. The motor drives the bidirectional lead screw to rotate, causing the two heat sealing boxes to move closer to each other, thereby squeezing the two non-woven fabrics between the two hot press plates. This allows the top and bottom surfaces of the two non-woven fabrics stacked together to be heated and squeezed, achieving uniform heating and pressure on the top and bottom surfaces of the non-woven fabrics and improving the effect of hot pressing of the non-woven fabrics.

[0019] 2. A dust-collecting plate is placed against the side of the non-woven fabric to be heat-pressed. The mesh on the dust-collecting plate contacts the non-woven fabric. An external vacuum cleaner draws airflow into the suction chamber of the dust-collecting plate through the suction pipe, thereby removing dust and impurities adhering to the surface of the non-woven fabric. This ensures the cleanliness of the non-woven fabric before heat pressing, improving the quality of the subsequent heat-sealed fabric. As the heat-pressing plate moves down and squeezes the non-woven fabric, the inclined dust-collecting plate can rotate to a straight position. Then, the electric push rod inside the support assembly, through the support block, allows... Two suction plates in a flat position move closer to each other, allowing them to suction dust while simultaneously supporting the non-woven fabric with a hot press plate. When the non-woven fabric is sandwiched between the suction plate and the hot press plate, it can be preheated with the help of the hot press plate. In addition, a torsion spring is sleeved between the suction plate and the positioning shaft. When the suction plate rotates from an inclined state to a flat state, the torsion spring is in a torsional contraction state. The elastic force of the torsion spring makes the suction plate press the non-woven fabric tightly against the hot press plate for preheating, thus improving the preheating effect.

[0020] 3. By moving the two heat sealing boxes closer to each other, the included angle between the two non-woven fabrics arranged in a V-shape gradually decreases. During the process of the heat sealing boxes pressing down on the non-woven fabric, the non-woven fabric drags the two spinning rollers to move along the center of the support frame. The elasticity of the return spring on the telescopic component hinders the movement of the spinning rollers, thereby keeping the non-woven fabric to be heat-pressed in a taut state and preventing wrinkles in the part of the non-woven fabric from affecting the heat-pressing of the two non-woven fabrics.

[0021] 4. The motor drives the two-way lead screw to rotate, causing the two support components and the two dust suction plates to move in opposite directions, thus removing the dust suction plates from the non-woven fabric. At this time, the two stacked non-woven fabrics are clamped between the two hot press plates. Then, the two hot press plates continue to move closer and press the stacked non-woven fabrics together. The non-woven fabric after hot pressing is transferred out from the two limit rollers. After hot pressing is completed, the electric push rod drives the hot press plate away from the non-woven fabric. Then, the external air pump draws air into the exhaust pipe of the heat sealing box, so that the harmful gases in the space where the non-woven fabric is hot pressed are drawn away and collected, preventing the harmful gases from being absorbed by the staff.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-8As shown, a heat-sealing machine for antibacterial, biodegradable, and environmentally friendly composite nonwoven fabric includes a base plate. Two support frames 100 are fixed to one end of the top surface of the base plate. Movable blocks 110 are slidably engaged at the top and bottom of each support frame 100. A connecting shaft 200 is detachably and rotatably inserted between the two movable blocks 110 arranged opposite each other on the two support frames 100. A weaving roller 210 is fixed to the outside of the connecting shaft 200. Tensioning mechanisms 300 are provided at the top and bottom of each support frame 100. The tensioning mechanism 300 includes two positioning wheels 310, two positioning wheels 320, and a movable wheel 330. A telescopic component 340 is connected to the movable wheel 330 and the support frame 100. A belt is connected to the multiple positioning wheels 310, positioning wheels 320, and movable wheels 330. Two C-shaped plates 400 are fixed in the middle of the top surface of the base plate. Inside the two C-shaped plates 400, a bidirectional lead screw 410 and a guide shaft 420 are respectively installed. The top and bottom ends of the bidirectional lead screw 410 are screwed to a heat sealing box 500. The open end of the heat sealing box 500 is slidably connected to a heat pressing plate 510. A guide frame 600 is fixed in the middle of the top surface of the base plate. A bidirectional lead screw 610 is rotatably connected inside the guide frame 600. Both ends of the bidirectional lead screw 610 are screwed to a support assembly 700. A positioning shaft 800 is fixed at the top of the support assembly 700. A dust suction plate 810 is rotatably connected to one end of the positioning shaft 800. Two columns 900 are fixed at one end of the top surface of the base plate away from the support frame 100. Two limit rollers 910 are rotatably connected between the two columns 900.

[0033] The support assembly 700 includes a support base 710 screwed into the bidirectional lead screw 610. A rectangular blind hole is provided at the top of the support base 710, and an electric push rod 720 is fixed inside the rectangular blind hole. A support block 730 is fixed to the output end of the electric push rod 720. The support block 730 is inserted and fixed to a corresponding positioning shaft 800. The electric push rod 720, moving the support block 730 up and down, allows the positioning shaft 800 to move the flat dust collection plate 810 up and down, facilitating the flattening of the non-woven fabric between the two dust collection plates 810. A motor 620 for driving the bidirectional lead screw 610 to rotate is fixed to one end of the frame 600. A fixed seat 813 is fixed to one side of the dust suction plate 810 and rotates with the positioning shaft 800 at the corresponding position. A torsion spring is provided between the fixed seat 813 and the positioning shaft 800. The fixed seats 813 on the two dust suction plates 810 are staggered so that the fixed seats 813 do not interfere with the movement of the dust suction plates 810 when the two dust suction plates 810 move close to each other. The elastic force of the torsion spring can make the dust suction plate 810 press the non-woven fabric tightly against the hot press plate 510.

[0034] The suction plate 810 has a mesh 811 on the side near the non-woven fabric. A suction chamber communicating with the mesh 811 is located inside the suction plate 810. A nozzle communicating with the suction chamber is fixed to the edge of the suction plate 810. A suction pipe 812 is fixedly connected to the outside of the nozzle and is connected to the suction pipe of an external vacuum cleaner. This allows dust on the non-woven fabric to be sucked into the suction chamber by the mesh 811 and then transported to the outside through the suction pipe 812. The heat sealing box 500 has a fixedly connected... The second connector has an externally fixed air extraction pipe 520. The air extraction pipe 520 is connected to the air extraction end of an external air pump via a flexible hose. Inside the heat sealing box 500, there are two fixed electric push rods 530. The output end of the electric push rods 530 is fixedly connected to the heat pressing plate 510. After the heat pressing plate 510 leaves the non-woven fabric, the second connector connects the space between the non-woven fabric and the heat pressing plate 510, and then the air extraction pipe 520 draws air from the second connector to remove harmful gases generated during the heat pressing process of the non-woven fabric.

[0035] Both ends of the bidirectional lead screw 410 are rotatably connected to the C-shaped plate 400, and both ends of the guide shaft 420 are fixedly connected to the C-shaped plate 400. A connecting block fixedly connected to the base plate is fixed on the bottom surface of the C-shaped plate 400. A motor 430 for driving the bidirectional lead screw 410 is fixed inside one of the C-shaped plates 400. The motor 430 drives the bidirectional lead screw 410 to rotate, facilitating the movement of the two heat sealing boxes 500 towards each other or away from each other. A dual-axis motor 120 is fixed between the top and bottom of the two support frames 100. One positioning wheel 310 is fixedly connected to the output end of the dual-axis motor 120, and the other positioning wheel 310 is fixedly connected to the connecting shaft 200. The second positioning wheel 320 is connected to the support frame 100. The system is connected by a dual-axis motor 120 that drives a positioning wheel 310 to rotate. Under the transmission of the belt, another positioning wheel 310 drives a connecting shaft 200 to rotate, which in turn causes the spinning roller 210 to rotate and release the nonwoven fabric. The telescopic component 340 includes a sleeve with a sliding rod slidably inserted inside. The sliding rod is rotatably connected to a moving wheel 330. A return spring is fixed between the sleeve and the sliding rod. Both ends of the support frame 100 are fixed with fixing blocks 130 that are fixedly connected to the corresponding sleeves. As the spinning roller 210 moves along the support frame 100, the belt pulls the moving wheel 330. The moving wheel 330 squeezes the return spring through the sliding rod, so that the nonwoven fabric drags the spinning roller 210 to move. It needs to overcome the elastic force of the return spring, and the elastic force of the return spring keeps the nonwoven fabric in a taut state.

[0036] Working principle: Refer to the instruction manual for usage. Figure 1The nonwoven fabric on the two spinning rollers 210 is arranged in a V-shape and gathered at the positions of the two limiting rollers 910. During hot pressing, the motor 430 drives the bidirectional lead screw 410 to rotate, causing the two heat sealing boxes 500 to move closer to the nonwoven fabric. At this time, one end of the heat sealing box 500 is gradually pressing down on the nonwoven fabric, and the nonwoven fabric begins to drag the spinning rollers 210 towards the middle of the support frame 100. The moving blocks 110 at both ends of the spinning rollers 210 slide along the support frame 100. At this time, the moving wheel 330 on the tensioning mechanism 300 pushes the slide bar, causing the slide bar to squeeze the return spring inside the sleeve, so that the nonwoven fabric can overcome the return spring during the movement. The compression force of the positioning spring keeps the non-woven fabric between the heat-sealing plate 510 and the suction plate 810 taut (the dual-axis motor 120 can rotate appropriately to make the belt drive the positioning wheel 310 at the end of the connecting shaft 200 to rotate, so that the fabric roller 210 can rotate to release the non-woven fabric and avoid the non-woven fabric from being too taut). As the heat-sealing box 500 moves towards the non-woven fabric, the suction plate 810 gradually rotates on the positioning shaft 800 to a flat state. Then, the mesh 811 on the suction plate 810 comes into contact with the non-woven fabric. The external vacuum cleaner draws airflow into the suction chamber of the suction plate 810 through the suction pipe 812, thereby making the non-woven fabric... Dust and impurities on the fabric surface are sucked away to ensure the nonwoven fabric is clean and tidy before hot pressing. Furthermore, a torsion spring is fitted between the suction plate 810 and the positioning shaft 800. When the suction plate 810 rotates from an inclined state to a straight state, the torsion spring is in a torsional contraction state. The spring force allows the suction plate 810 to tightly press the nonwoven fabric against the hot pressing plate 510. At this time, the hot pressing plate 510 can preheat the nonwoven fabric. Then, the motor 620 drives the bidirectional lead screw 610 to rotate, causing the two support components 700 to move the two suction plates 810 away from the nonwoven fabric, ensuring there is no gap between the two pieces of nonwoven fabric. The dust-collecting plate 810 and the two heat-sealing boxes 500 continue to move closer to each other, so that the heat-pressing plate 510 is pressed onto the stacked non-woven fabric, thus achieving heat pressing of the non-woven fabric. The electric push rod 530 inside the heat-sealing box 500 takes the heat-pressing plate 510 away from the non-woven fabric, so that the nozzle 2 connected to the air extraction pipe 520 is facing the heat-pressed non-woven fabric. The external air pump draws air into the air extraction pipe 520 through the hose, so that the harmful gases generated on the surface of the non-woven fabric after the heat pressing is completed are concentrated and sucked out. Then, the external winding roller rotates to wind up the heat-pressed non-woven fabric, and the weaving roller 210 rotates to release the new non-woven fabric to be heat-pressed. The two heat-sealing boxes 500 leave the non-woven fabric.
