Description

Technical Field

[0001] The present application relates to the field of rubber pad processing, and in particular to a rubber pad embossing production line and a production method. Background Art

[0002] At present, rubber mat products such as floor mats and yoga mats are widely used in life. Due to the aesthetics of the products, it is often necessary to process patterns on the rubber mats.

[0003] In the related art, in order to process patterns on rubber pads, laser marking or direct embossing using a mold is usually used.

[0004] The above-mentioned related technologies have the following defects: the efficiency of laser marking is low, and because rubber has elasticity, the embossing is easy to rebound when the mold is used for direct embossing, and the embossing effect is poor. Summary of the invention

[0005] In order to improve the embossing efficiency while ensuring the embossing quality, the present application provides a rubber pad embossing production line and a production method.

[0006] The present application provides a rubber pad embossing production line and production method using the following technical solutions: A rubber pad embossing production line comprises a frame, a drying box, a conveyor mesh belt, a first pressing assembly and a second pressing assembly, wherein the drying box and the conveyor mesh belt are both installed on the frame along the length direction of the frame; The middle part of the conveyor mesh belt is located in the drying box, and a plurality of forming holes are arranged on the belt surface of the conveyor mesh belt; The first pressing assembly is located at the feeding side of the drying box; the first pressing assembly includes a first static pressure roller and a first dynamic pressure roller which are parallel to each other, the first static pressure roller is arranged on the inner side of the conveying mesh belt and is rotatably connected to the frame; the first dynamic pressure roller is arranged above the conveying mesh belt, is rotatably connected to the frame, and can move toward the first static pressure roller; The second pressing assembly is located in the drying box; the second pressing assembly includes a second static pressure roller and a second dynamic pressure roller parallel to each other, the second static pressure roller is arranged on the inner side of the conveyor mesh belt and is rotatably connected to the frame; the second dynamic pressure roller is arranged above the conveyor mesh belt, is rotatably connected to the frame, and can move toward the second static pressure roller.

[0007] By adopting the above technical solution, when producing a rubber pad, the first release film, liquid rubber and the second release film are taken as raw materials, the liquid rubber is spread flat between the first release film and the second release film, and on the conveying surface of the conveyor mesh belt, the first release film, the liquid rubber and the second release film are sequentially attached from bottom to top to form a composite layer. When the composite layer passes through the first pressing component, the first dynamic pressure roller moves toward the first static pressure roller to pre-press the composite layer, and the liquid rubber enters the forming hole on the conveyor mesh belt under the pressure of the first dynamic pressure roller and the action of its own weight. The conveyor mesh belt conveys the composite layer to the drying box, and when the liquid rubber is baked in the drying box to form a semi-solid rubber pad, the second dynamic pressure roller moves toward the second static pressure roller, and presses the composite layer on the conveyor mesh belt again, and then forms a preset pattern on the semi-solid rubber pad. Then the drying box continues to dry the semi-solid rubber pad, so that the semi-solid rubber pad is completely solidified and fixed into a rubber pad. After the conveyor belt conveys the composite layer to the outside of the drying box, the first release film and the second release film are torn off the rubber pad, and the rubber pad is collected. In addition, the present application realizes the continuous production of the rubber pad while ensuring the embossing quality, and improves the embossing efficiency of the rubber pad.

[0008] Preferably, the feed end and the discharge end of the drying box are respectively provided with a semi-curing chamber and a full-curing chamber, and the semi-curing chamber is connected to the full-curing chamber; The semi-curing chamber is provided with a feed inlet at one end away from the full-curing chamber; The full curing chamber is provided with a discharge port at one end away from the semi-curing chamber; The middle belt body of the conveyor mesh belt passes through the feed port, the semi-curing chamber, the full-curing chamber and the discharge port in sequence; The second pressing assembly is located in the semi-curing chamber.

[0009] By adopting the above technical solution, when the first pressing component pre-presses the composite layer, the liquid rubber itself cannot be shaped yet. If it is directly dried at this time, the texture on the surface of the rubber pad is prone to defects. After the composite layer enters the semi-curing chamber, the liquid rubber is baked by the semi-curing chamber to form a semi-solid rubber pad. The semi-solid rubber pad now has certain shaping and shaping capabilities. At this time, the second pressing component presses the composite layer on the conveyor belt again, and a stable preset pattern can be formed on the semi-solid rubber pad. After the conveyor belt transports the composite layer to the full curing chamber, the semi-solid rubber pad is dried and shaped by the full curing chamber to form a completely solidified and fixed rubber pad. The design of the semi-curing chamber and the full curing chamber enables the liquid rubber to be gradually cured at different stages, which is conducive to the effective molding of the texture on the surface of the rubber pad.

[0010] Preferably, the first static pressure roller, the first dynamic pressure roller, the second static pressure roller and the second dynamic pressure roller are all arranged along the width direction of the conveyor mesh belt.

[0011] By adopting the above technical solution, the strength and direction of the composite layer when being pressed at the front and back are consistent, thereby avoiding quality defects of the rubber pad caused by uneven pressure.

[0012] Preferably, a tension adjustment roller and a plurality of supporting rollers are provided on the inner side of the conveyor mesh belt, and the plurality of supporting rollers are distributed along the circumference of the conveyor mesh belt and are all rotatably connected to the frame; The tension adjustment roller is installed on the frame in a liftable manner and is also rotatably connected to the frame.

[0013] By adopting the above technical solution, the tension adjustment roller can effectively adjust the tension of the conveyor belt, ensuring that the conveyor belt always maintains appropriate tension during the production process, avoiding material deviation or accumulation caused by relaxation. At the same time, multiple supporting rollers are evenly distributed along the circumference of the conveyor belt, further improving the stability and carrying capacity of the conveyor belt, reducing jitter and deformation during the conveying process, thereby ensuring product quality and production efficiency.

[0014] Preferably, both ends of the conveyor mesh belt are provided with a reversing roller rotatably connected to the frame, and the reversing roller is sleeved with two spaced-apart limiting rings, and the limiting rings are slidably connected to the reversing roller; The conveyor belt is located between the two limiting rings.

[0015] By adopting the above technical solution, the two limit rings on the reversing roller can effectively prevent the conveyor belt from deflecting or falling off during operation, ensuring the stability and reliability of the conveyor belt. At the same time, the design of the sliding connection between the limit ring and the reversing roller allows the position of the limit ring to be adjusted according to actual needs, further improving the adaptability and flexibility of the equipment.

[0016] Preferably, the reversing roller comprises an outer circle and inner hexagonal tube, a bidirectional screw rod, two nuts and two sleeves, and the outer circle and inner hexagonal tube are rotatably connected to the frame; The side walls at both ends of the outer circle inner hexagonal tube are respectively provided with side long holes; Both ends of the outer hexagonal inner tube are closed, the bidirectional screw rod is coaxially arranged in the outer hexagonal inner tube, and the two ends of the bidirectional screw rod are respectively connected to the two closed ends of the outer hexagonal inner tube; The two nuts are both arranged in the outer circle inner hexagonal tube, and are both slidably connected to the outer circle inner hexagonal tube, and are also respectively threadedly connected to the two ends of the bidirectional screw rod; The two sleeves are correspondingly arranged with the two nuts, the sleeves are sleeved on the outer circle inner hexagonal tube, and the first ends of the sleeves are connected with the corresponding nuts via a connecting piece located in the side long hole; The two sleeves are correspondingly arranged with the two limiting rings, and the second ends of the sleeves are coaxially connected with the corresponding limiting rings.

[0017] By adopting the above technical solution, the design of the reversing roller enables the limit ring to be accurately adjusted in the width direction of the conveyor belt, thereby effectively avoiding the problem of belt deviation during transportation. At the same time, the coordinated use of the bidirectional screw and nut enables the rapid adjustment of the position of the limit ring and improves production efficiency. In addition, the design structure is simple and compact, which is convenient for maintenance and replacement of parts.

[0018] Preferably, the first end of the supporting roller, the first end of the tension adjusting roller, the first end of the outer circle inner hexagonal tube, the first end of the first static pressure roller, the first end of the first dynamic pressure roller, the first end of the second static pressure roller and the first end of the second dynamic pressure roller are all rotatably connected to the first end of the frame in the width direction; In the width direction of the frame, a side door is provided on a side of the drying box away from the first end of the frame.

[0019] By adopting the above technical solution, the conveyor mesh belt plays the role of a mold during the liquid rubber shaping process. When processing rubber pads with different patterns, the conveyor mesh belt with corresponding shaped forming holes needs to be replaced. When replacing the conveyor mesh belt, open the side door, adjust the position of the tension adjustment roller to loosen the conveyor mesh belt, move the conveyor mesh belt to the second end of the supporting roller, so that the conveyor mesh belt is detached from the supporting roller, the tension adjustment roller, the outer circle inner hexagonal tube, the first static pressure roller, the first dynamic pressure roller, the second static pressure roller and the second dynamic pressure roller, and then put the new conveyor mesh belt on the supporting roller, the tension adjustment roller, the outer circle inner hexagonal tube, the first static pressure roller, the first dynamic pressure roller, the second static pressure roller and the second dynamic pressure roller, and adjust the position of the tension adjustment roller to tighten the conveyor mesh belt, thereby realizing the rapid replacement of the conveyor mesh belt. At the same time, it is convenient for operators to maintain and clean the interior of the drying box and the conveyor mesh belt, thereby improving production efficiency and equipment reliability.

[0020] Preferably, the feed end of the conveyor mesh belt is provided with a first unwinding roller and a second unwinding roller, the first unwinding roller is arranged on the lower side of the conveyor mesh belt, and the second unwinding roller is arranged on the upper side of the conveyor mesh belt, and both are rotatably connected to the frame.

[0021] By adopting the above technical solution, it is possible to more conveniently unwind and pull the material during the production process, ensuring that the first release film and the second release film can enter the subsequent process straight and stably, thereby improving the continuity and efficiency of production. At the same time, this design can also effectively reduce product defects caused by material wrinkles or deviations, and improve product quality and consistency.

[0022] A rubber pad embossing production method, based on the above-mentioned rubber pad embossing production line, comprises the following steps: S1, loading, putting the first release film roll on the first unwinding roller, and putting the second release film roll on the second unwinding roller; S2, preheating the drying box, operating the drying box, and raising the internal temperature of the drying box to 120° C.-130° C.; S3, pulling the first release film and the second release film, and pulling the leading end of the first release film roll and the leading end of the second release film roll to between the first static pressure roller and the first dynamic pressure roller; S4, applying liquid rubber on the first release film, placing liquid rubber between the first release film and the second release film, applying the liquid rubber evenly on the first release film, and laminating the first release film, the liquid rubber and the second release film in sequence from bottom to top to form a composite layer; S5, initially pressing the liquid rubber onto the conveyor mesh belt, the conveyor mesh belt conveying the composite layer through the drying box, when the composite layer passes through the first pressing assembly, the first dynamic pressure roller moves toward the first static pressure roller to pre-press the composite layer, and the liquid rubber enters the forming hole on the conveyor mesh belt under the pressure of the first dynamic pressure roller and the action of its own weight; S6, pressing the liquid rubber onto the conveyor mesh belt for a second time, the conveyor mesh belt conveying the composite layer into the semi-curing chamber, the liquid rubber being baked into a semi-solid rubber pad by the semi-curing chamber, the second dynamic pressure roller moving toward the second static pressure roller, pressing the composite layer onto the conveyor mesh belt again, and then forming a preset pattern on the semi-solid rubber pad; S7, drying and shaping the semi-solid rubber pad, after the conveyor mesh conveys the composite layer to the full curing chamber, the semi-solid rubber pad is dried and shaped by the full curing chamber to form a completely solidified rubber pad; S8, discharging: after the conveyor belt conveys the composite layer to the outside of the drying box, the first release film and the second release film are torn off from the rubber pad, and the rubber pad is collected.

[0023] By adopting the above technical solution, by respectively sleeved the first release film roll and the second release film roll on the first unwinding roller and the second unwinding roller, the stable supply of materials is ensured and the degree of automation of production is improved. The temperature inside the drying box is increased to 120℃-130℃, which ensures the rapid curing of the liquid rubber in the subsequent process, shortens the production cycle, and improves the product quality. The first release film and the second release film are pulled between the first static pressure roller and the first dynamic pressure roller to ensure the accurate position and close fit of the materials and avoid the generation of bubbles and wrinkles. The liquid rubber is evenly spread on the first release film to form a flat composite layer with uniform thickness, which provides a good foundation for subsequent molding. The composite layer is pre-pressed by moving the first dynamic pressure roller toward the first static pressure roller, so that the liquid rubber enters the molding hole on the conveyor belt under pressure, and the pattern structure is initially formed, which enhances the aesthetics and functionality of the product. The conveyor belt conveys the composite layer into the semi-curing chamber. After the liquid rubber is dried to a semi-solid state, the second dynamic pressure roller presses the composite layer onto the conveyor belt again, further deepening the fineness of the pattern and ensuring the clarity and consistency of the pattern. The composite layer is thoroughly dried and shaped in the full curing chamber, and finally forms a stable rubber pad, ensuring the durability and stability of the product. The composite layer is sent out of the drying box, and the first release film and the second release film are torn off the rubber pad, realizing the automatic collection of the finished product, improving production efficiency and product yield. The rubber pad embossing production method can efficiently and continuously produce patterns on the rubber pad while ensuring the embossing quality, thereby improving the embossing efficiency on the rubber pad.

This application realizes the continuous production of rubber pads while ensuring the embossing quality, and improves the embossing efficiency of rubber pads 2. The present application provides a first pressing component and a second pressing component, so that the liquid rubber can be pressed for a second time after the initial forming, thereby ensuring that the liquid rubber fully fills the forming holes on the conveyor belt, improving the clarity and stability of the embossing, and solving the embossing rebound problem caused by direct embossing with a mold in the prior art; 3. The present application divides the drying box into a semi-curing chamber and a full-curing chamber, so that the liquid rubber can be dried to a semi-solid state after the initial embossing, and then the secondary embossing is performed, which further improves the quality and efficiency of the embossing and avoids the uneven phenomenon that may be caused by a single drying process; BRIEF DESCRIPTION OF THE DRAWINGS In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings required for use in the description of the embodiments will be briefly introduced below.

[0041] Reference Figure 4 A rubber pad embossing production method, based on the above-mentioned rubber pad embossing production line, comprises the following steps: S1, loading, rolling the first release film 71 onto the first unwinding roller 7, and rolling the second release film 81 onto the second unwinding roller 8; S2, preheating the drying box 2, operating the drying box 2, and raising the internal temperature of the drying box 2 to 120°C-130°C; S3, pulling the first release film 71 and the second release film 81, and pulling the leading end of the first release film 71 roll and the leading end of the second release film 81 roll to between the first static pressure roller 51 and the first dynamic pressure roller 52; S4, applying liquid rubber 9 on the first release film 71, placing liquid rubber 9 between the first release film 71 and the second release film 81, applying liquid rubber 9 evenly on the first release film 71, and laminating the first release film 71, liquid rubber 9 and second release film 81 in sequence from bottom to top to form a composite layer; S5, the liquid rubber 9 is initially pressed onto the conveyor mesh belt 3, and the conveyor mesh belt 3 conveys the composite layer to the drying box 2. When the composite layer passes through the first pressing assembly 5, the first dynamic pressure roller 52 moves toward the first static pressure roller 51 to pre-press the composite layer. The liquid rubber 9 enters the forming hole 301 on the conveyor mesh belt 3 under the pressure of the first dynamic pressure roller 52 and the action of its own weight; S6, the liquid rubber 9 is pressed onto the conveyor mesh belt 3 for a second time, the conveyor mesh belt 3 conveys the composite layer into the semi-curing chamber 202, the liquid rubber 9 is baked into a semi-solid rubber pad by the semi-curing chamber 202, the second dynamic pressure roller 62 moves toward the second static pressure roller 61, and the composite layer is pressed onto the conveyor mesh belt 3 again, thereby forming a preset pattern on the semi-solid rubber pad; S7, drying and shaping the semi-solid rubber pad. After the conveyor belt 3 conveys the composite layer to the full curing chamber 203, the semi-solid rubber pad is dried and shaped by the full curing chamber 203 to form a completely solidified rubber pad; S8, discharging: after the conveyor belt 3 conveys the composite layer to the outside of the drying box 2, the first release film 71 and the second release film 81 are torn off from the rubber pad, and the rubber pad is collected.

[0042] Reference Figure 4 In the embodiment of the present application, by respectively sleeve-mounting the first release film 71 and the second release film 81 on the first unwinding roller 7 and the second unwinding roller 8, the stable supply of materials is ensured and the degree of automation of production is improved. The internal temperature of the drying box 2 is increased to 120°C-130°C, which ensures the rapid curing of the liquid rubber 9 in the subsequent process, shortens the production cycle, and improves the product quality. The first release film 71 and the second release film 81 are pulled between the first static pressure roller 51 and the first dynamic pressure roller 52 to ensure the accurate position and close fit of the materials and avoid the generation of bubbles and wrinkles. The liquid rubber 9 is evenly spread on the first release film 71 to form a smooth composite layer with uniform thickness, which provides a good foundation for subsequent die pressing. The composite layer is pre-pressed by moving the first dynamic pressure roller 52 toward the first static pressure roller 51, so that the liquid rubber 9 enters the forming hole 301 on the conveyor mesh belt 3 under pressure, and a pattern structure is initially formed, which enhances the aesthetics and functionality of the product. The conveyor mesh belt 3 delivers the composite layer to the semi-curing chamber 202. After the liquid rubber 9 is dried to a semi-solid state, the second dynamic pressure roller 62 presses the composite layer onto the conveyor mesh belt 3 again, further deepening the fineness of the pattern and ensuring the clarity and consistency of the pattern. The composite layer is thoroughly dried and shaped in the full curing chamber 203, and finally forms a stable rubber pad, ensuring the durability and stability of the product. The composite layer is sent out of the drying box 2, and the first release film 71 and the second release film 81 are torn off the rubber pad, realizing the automatic collection of the finished product, improving the production efficiency and product yield. The rubber pad embossing production method can efficiently and continuously produce patterns on the rubber pad while ensuring the embossing quality, thereby improving the embossing efficiency on the rubber pad.

[0043] The implementation principle of a rubber pad embossing production line and production method in the embodiment of the present application is as follows: The first release film 71 is rolled onto the first unwinding roller 7, and the second release film 81 is rolled onto the second unwinding roller 8. Then, the drying box 2 is operated, and the internal temperature of the drying box 2 is preheated to 120°C-130°C.

[0044] The first end of the first release film 71 roll and the first end of the second release film 81 roll are pulled between the first static pressure roller 51 and the first dynamic pressure roller 52. The liquid rubber 9 is placed between the first release film 71 and the second release film 81, and the liquid rubber 9 is evenly spread on the first release film 71. The first release film 71, the liquid rubber 9 and the second release film 81 are sequentially attached from bottom to top to form a composite layer.

[0045] The conveyor mesh belt 3 and the drying box 2 convey the composite layer. When the composite layer passes through the first pressing component 5, the first dynamic pressure roller 52 moves toward the first static pressure roller 51 to pre-press the composite layer. The liquid rubber 9 enters the forming hole 301 on the conveyor mesh belt 3 under the pressure of the first dynamic pressure roller 52 and the action of its own weight.

[0046] The conveyor mesh belt 3 conveys the composite layer to the semi-curing chamber 202, and the liquid rubber 9 is baked in the semi-curing chamber 202 to form a semi-solid rubber pad. The second dynamic pressure roller 62 moves toward the second static pressure roller 61, and presses the composite layer on the conveyor mesh belt 3 again, thereby forming a preset pattern on the semi-solid rubber pad. After the conveyor mesh belt 3 conveys the composite layer to the full curing chamber 203, the semi-solid rubber pad is dried and shaped by the full curing chamber 203 to form a completely solidified rubber pad.

[0047] After the conveyor mesh belt 3 conveys the composite layer to the outside of the drying box 2, the first release film 71 and the second release film 81 are torn off from the rubber pad, and the rubber pad is collected.
