Description

Technical Field

[0001] This invention belongs to the field of waterproof membrane production, and particularly relates to a continuous apparatus for EPDM waterproof membrane production. Background Technology

[0002] EPDM rubber waterproof membranes are widely used in waterproofing applications such as building roofs, underground engineering, and water conservancy facilities due to their excellent weather resistance, aging resistance, and good physical and mechanical properties. Backed EPDM waterproof membranes typically have a non-woven fabric laminated to one side of the substrate as a reinforcing backing to improve their tensile strength and construction adaptability.

[0003] In the production process of EPDM waterproof membrane, after the raw materials are melted in the internal mixer, a vulcanizing agent needs to be added. However, because the internal temperature of the internal mixer is too high, the vulcanizing agent cannot be added during the mixing process. Therefore, after the material is melted, it needs to be fed into an open mill. After the melted raw material is slightly cooled, it is thinned by the open mill, and then the vulcanizing agent is added to the thinned material. In order to fully incorporate the vulcanizing agent into the raw material, it is necessary to stack the material together and then thin it again to obtain the preliminary shaped material. In the operation, multiple pieces of equipment need to work together at the same time, and the vulcanizing agent also needs to be added manually. Therefore, the work efficiency needs to be improved.

[0004] Therefore, there is an urgent need to develop a continuous EPDM waterproof membrane device that automatically adds vulcanizing agents and integrates the function of preliminary raw material forming. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a continuous device for EPDM waterproof membrane that automatically adds vulcanizing agent and integrates the function of preliminary raw material forming.

[0006] The technical solution is as follows: A continuous device for EPDM waterproof membrane includes a frame, a first thinning mechanism, a vulcanizing agent adding mechanism, a second thinning mechanism, a gathering mechanism, and a discharge conveying mechanism. The first thinning mechanism is installed in the lower part of the frame, and is used for the first and third thinning of the material. The vulcanizing agent adding mechanism is installed on the side of the first thinning mechanism. After the material is thinned for the first time, it enters the vulcanizing agent adding mechanism. The second thinning mechanism is set on the frame above the first thinning mechanism, and is used for the second thinning of the material. The gathering mechanism is set on the frame on the side of the second thinning mechanism, and gathers the material after the first thinning. The gathering mechanism is located above the vulcanizing agent adding mechanism. The discharge conveying mechanism is rotatably installed on the upper part of the frame, and the position of the discharge conveying mechanism can be changed.

[0007] Furthermore, the first thinning mechanism includes a first roller, a second roller, a first motor, a first pulley, a first guide rail, a second pulley, a spring, and a flat belt. The first roller and the second roller are symmetrically rotatably mounted on the lower part of the frame. The first motor is mounted on the side of the frame, and the output shaft of the first motor is connected to one end of the first roller. The first pulley is connected to one end of the first roller and the second roller on the same side. The first guide rail is mounted on the frame on the side of the first pulley. The second pulley is symmetrically slidably connected in the first guide rail. A spring is connected between the second pulley and the first guide rail. The flat belt is wound around the first pulley and the second pulley. The spring is in a deformed state, so that the flat belt is in a taut state. The flat belt rotates the first roller and the second roller in opposite directions.

[0008] Furthermore, the vulcanizing agent adding mechanism includes a placement frame, a steering shaft, and brushes. An upward-facing placement frame is provided on the frame on the side of the first roller. A steering shaft parallel to the first roller is rotatably installed inside the placement frame. Brushes are symmetrically arranged at the opening at the top of the placement frame.

[0009] Furthermore, the second thinning mechanism includes a third roller, a fourth roller, gears, and a second motor. The third roller, parallel to the first roller, is rotatably mounted on the upper part of the frame, and the fourth roller is rotatably mounted on the frame below the third roller. Gears are provided on the same side of both the third and fourth rollers, and the two gears mesh to keep the third and fourth rollers in opposite motion states. The second motor is provided on the side of the frame, and the output shaft of the second motor is connected to the end of the third roller.

[0010] Furthermore, the gathering mechanism includes a first lead screw, a third motor, a limit rod, a nut, a clamping rod, and a fastening screw. The limit rod is symmetrically and rotatably mounted on the frame on the side of the fourth roller. The first lead screw is rotatably mounted on the frame below the limit rod. The third motor is mounted on the frame at the end of the first lead screw. The output shaft of the third motor is connected to the end of the first lead screw. Two nuts are threadedly connected to the first lead screw. Each nut is equipped with a clamping rod, which is positioned between the two limit rods to limit and guide the clamping rod. The nuts are threadedly connected with fastening screws.

[0011] Furthermore, the discharge conveying mechanism includes a swing arm, a conveying shaft, and a limiting shaft. The swing arm is rotatably mounted on the side of the frame, and the end of the swing arm is rotatably mounted with a conveying shaft parallel to the third roller. A positioning groove is provided on the side of the swing arm, and a limiting shaft is provided on the frame along the rotation path of the positioning groove. When the conveying shaft is above the frame, it is in a retracted state, and when the swing arm rests on the limiting shaft, it is in a conveying state.

[0012] Furthermore, it also includes a material gathering mechanism. The material gathering mechanism is provided above the first roller and the second roller. The material gathering mechanism includes a bidirectional lead screw, a connecting rod and a clamping plate. The bidirectional lead screw is rotatably mounted on the frame above the first roller and the second roller. The two ends of the bidirectional lead screw are threadedly connected to the connecting rod. The end of the connecting rod is connected to the clamping plate. The bottom of the clamping plate is located between the first roller and the second roller. The first roller and the second roller limit the clamping plate.

[0013] Furthermore, it also includes a scraping mechanism. The scraping mechanism is installed on the frame at the third and fourth rollers. The scraping mechanism includes a first scraper and a second scraper. Both the first scraper and the second scraper are rotatably mounted on the frame by torsion springs. The side of the first scraper contacts the surface of the third roller, and the side of the second scraper contacts the surface of the fourth roller.

[0014] Furthermore, it also includes a cutting mechanism. The cutting mechanism is installed on the frame on the side of the first roller. The cutting mechanism includes a cylinder, a second guide rail, a reciprocating screw, a cutter, a limit switch, and rollers. Cylinders are installed on the frames at both ends of the first roller. The output ends of the cylinders are connected to the second guide rail. The reciprocating screw is rotatably connected to the second guide rail. The cutter is connected to the reciprocating screw. Limit switches are installed at both ends of the second guide rail. The limit switches are linearly connected to the cylinders. Rollers are connected to both ends of the reciprocating screw.

[0015] Furthermore, it also includes a collection frame, which is installed on the frame at the bottom of the first thinning mechanism.

[0016] This invention uses a first thinning mechanism to thin the material into a carpet-like shape. After the first thinning, the material enters a vulcanizing agent addition mechanism for automatic vulcanizing agent addition. A second thinning mechanism then thins the material a second time, allowing the vulcanizing agent to be better incorporated into the material. After the second thinning, the material returns to the first thinning mechanism for a third thinning. By integrating the material thinning and vulcanizing agent addition into one process, the equipment is easier to operate and reduces the labor intensity of workers. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0029] Example: A continuous device for EPDM waterproof membrane, such as... Figures 1-7As shown, the assembly includes a frame 1, a first thinning mechanism 2, a vulcanizing agent adding mechanism 3, a second thinning mechanism 4, a gathering mechanism 5, and a discharge conveying mechanism 6. The first thinning mechanism 2 is installed in the lower part of the frame 1, and is connected to the left and right walls of the frame 1. The first thinning mechanism 2 is used for the first and third thinning of the material, thinning it by rotation. The vulcanizing agent adding mechanism 3 is installed on the side of the first thinning mechanism 2. After the material undergoes the first thinning, it enters the vulcanizing agent adding mechanism 3, where the vulcanizing agent is added to the thinned material. This allows for better addition of the vulcanizing agent to the thinned material. The frame 1 is located above the first thinning mechanism 2. A second thinning mechanism 4 is provided on the upper part of the frame 1, which is installed between the left and right walls. The second thinning mechanism 4 is used to thin the material a second time. The second thinning mechanism 4 also thins the material by rotation. A gathering mechanism 5 is provided on the frame 1 on the side of the second thinning mechanism 4. The gathering mechanism 5 gathers the material after the first thinning and then enters the second thinning mechanism 4 for thinning again, so that the vulcanizing agent can be added to the material better, which facilitates the subsequent vulcanization of the material. The gathering mechanism 5 is above the vulcanizing agent adding mechanism 3. A discharge conveying mechanism 6 is rotatably installed on the upper part of the frame 1. The position of the discharge conveying mechanism 6 can be changed.

[0030] In use: After being mixed, the material is placed on the first thinning mechanism 2, which then performs the first thinning, pressing the material into a carpet-like shape. After the first thinning, the material enters the vulcanizing agent adding mechanism 3, where vulcanizing agent is added. The material is then placed on the gathering mechanism 5, where it is gathered and enters the second thinning mechanism 4 for a second thinning, during which the vulcanizing agent is better incorporated. After the second thinning, the material returns to the first thinning mechanism 2. At this point, the discharge conveying mechanism 6 is rotated to the front of the frame 1, and the material after the third thinning is discharged from the discharge conveying mechanism 6. This equipment integrates thinning and vulcanizing agent addition, making the equipment simpler to operate and reducing the labor intensity of workers.

[0031] like Figure 3As shown, the first thinning mechanism 2 includes a first roller 21, a second roller 22, a first motor 23, a first pulley 24, a first guide rail 25, a second pulley 26, a spring 27, and a flat belt 28. The first roller 21 and the second roller 22 are symmetrically mounted on the lower part of the frame 1. The left and right ends of the first roller 21 and the second roller 22 are rotatably connected to the frame 1. The first motor 23 is fixedly mounted on the side of the frame 1 by bolts. The output shaft of the first motor 23 is connected to the right end of the first roller 21, driving the first roller 21 to rotate. The left ends of both the first roller 21 and the second roller 22 are connected to the first pulley 24. The frame 1 is mounted on the side of the first pulley 24. A first guide rail 25 is installed on the upper part, and a second pulley 26 is symmetrically slidably connected inside the first guide rail 25. A spring 27 is connected between the second pulley 26 and the first guide rail 25. A flat belt 28 is wound around the first pulley 24 and the second pulley 26. The spring 27 is in a deformed state, so that the flat belt 28 is in a taut state. The flat belt 28 rotates the first roller 21 and the second roller 22 in opposite directions. The material is placed between the first roller 21 and the second roller 22. The first motor 23 drives the first roller 21 to rotate. The material is squeezed and thinned by the oppositely rotating first roller 21 and second roller 22. The thinned material is then conveyed downward.

[0032] like Figure 4 As shown, the vulcanizing agent adding mechanism 3 includes a placement frame 31, a steering shaft 32, and a brush 33. The frame 1 on the side of the first roller 21 is provided with an upward-facing placement frame 31. The placement frame 31 is installed parallel to the first roller 21. The vulcanizing agent is placed in the placement frame 31. The steering shaft 32, which is parallel to the first roller 21, is rotatably installed inside the placement frame 31. After the material is thinned for the first time, it is wrapped around the steering shaft 32 from the rear side and then leaves the placement frame 31 from the front side of the steering shaft 32. The material inside the placement frame 31 is subjected to the addition of vulcanizing agent. The brush 33 is symmetrically arranged at the opening at the top of the placement frame 31. The material coming out of the placement frame 31 passes through the brush 33, and the brush 33 scrapes off the excess material on the surface.

[0033] like Figure 5As shown, the second thinning mechanism 4 includes a third roller 41, a fourth roller 42, a gear 43, and a second motor 44. The third roller 41, parallel to the first roller 21, is rotatably mounted between the left and right walls of the upper part of the frame 1. The fourth roller 42 is rotatably mounted between the left and right walls of the frame 1 below the front side of the third roller 41. Gears 43 are provided on the right side of both the third roller 41 and the fourth roller 42. The two gears 43 mesh, so that the third roller 41 and the fourth roller 42 maintain opposite motion. The second motor 44 is fixed to the right side of the frame 1 by bolts. The output shaft of the second motor 44 is connected to the end of the third roller 41. The second motor 44 drives the third roller 41 to rotate, and the gear 43 drives the fourth roller 42 to rotate in the opposite direction. After the material is gathered by the gathering mechanism 5, the material enters between the third roller 41 and the fourth roller 42. The material is thinned a second time by the oppositely rotating third roller 41 and the fourth roller 42. The thinned material is then conveyed downward.

[0034] like Figure 6 As shown, the gathering mechanism 5 includes a first lead screw 51, a third motor 52, a limit rod 53, a nut 54, a clamping rod 55, and a fastening screw 56. The limit rod 53 is rotatably mounted between the left and right walls of the frame 1 on the front side of the fourth roller 42. The first lead screw 51 is rotatably mounted between the left and right walls of the frame 1 below the limit rod 53. The third motor 52 is fixed to the frame 1 at the end of the first lead screw 51 by bolts. The output shaft of the third motor 52 is connected to the end of the first lead screw 51, and the first lead screw 51 is rotated by the third motor 52. Two nuts 54 are threadedly connected to the first lead screw 51. Each nut 54 is provided with a clamping rod 55. The clamping rod 55 is located between the two limit rods 53, which limit and guide the clamping rod 55. The first lead screw 51 drives the nuts 54 and the clamping rod 55 to move synchronously. The nuts 54 are threadedly connected with fastening screws 56.

[0035] After the material completes its first thinning operation through the first thinning mechanism 2 and passes through the vulcanizing agent addition mechanism 3, the material passes through the limiting rod 53 between the clamping rods 55 and then enters the second thinning mechanism 4. At this time, because the distance between the clamping rods 55 is less than the width of the material, the material needs to be stacked and folded together to pass through the limiting rod 53. After the vulcanizing agent is added to the material, the material is folded together before entering the second thinning mechanism 4, so that the vulcanizing agent added to the material can be better added into the material. When the second thinning mechanism 4 thins the material, the third motor 52 can be controlled to rotate, driving the nut 54 and the clamping rods 55 to move to the left or right, so that the material feeding position is changed, thereby realizing the material feeding in a dispersed manner. If the material needs to be fed in one place, the third motor 52 stops working and the nut 54 is tightened by the fastening screw 56, so that the nut 54 cannot move in a certain way during the feeding process, thereby fixing the feeding position.

[0036] like Figure 7 As shown, the discharge conveying mechanism 6 includes a swing arm 61, a conveying shaft 63, and a limiting shaft 64. The swing arm 61 is rotatably mounted on the left side of the frame 1. The end of the swing arm 61 is rotatably mounted with a conveying shaft 63 parallel to the third roller 41. The conveying shaft 63 extends to the right. A semi-circular positioning groove 62 is opened on the side of the swing arm 61. The limiting shaft 64 is provided on the frame 1 along the rotation path of the positioning groove 62. When the conveying shaft 63 is above the frame 1, it is in a retracted state. When the swing arm 61 rests on the limiting shaft 64, it is in a conveying state. After the material is squeezed by the second thinning mechanism 4, it is conveyed downward to the first thinning mechanism 2 for a third thinning. After the third thinning is completed, the conveying shaft 63 is rotated forward. The positioning groove 62 rests on the limiting shaft 64, so that the conveying shaft 63 is in front of the second thinning mechanism 4. The material is pulled forward and rests on the conveying shaft 63. The conveying shaft 63 supports the material, so that the material can be conveyed out better.

[0037] like Figure 8As shown, it also includes a material gathering mechanism 7. The material gathering mechanism 7 is arranged above the first roller 21 and the second roller 22. The material gathering mechanism 7 includes a bidirectional lead screw 71, a connecting rod 72, and a clamping plate 73. The bidirectional lead screw 71 is rotatably installed between the left and right walls of the frame 1 above the first roller 21 and the second roller 22. The two ends of the bidirectional lead screw 71 are threadedly connected to the connecting rod 72. The end of the connecting rod 72 is connected to the clamping plate 73. The bottom of the clamping plate 73 is located between the first roller 21 and the second roller 22. The first roller 21 and the second roller 22 limit the clamping plate 73. Before the material is placed for thinning, the bidirectional lead screw 71 is rotated to move the clamping plates 73 closer or further apart according to the required thinning width of the material. This adjusts the distance between the clamping plates 73 until the distance between the clamping plates 73 is equal to the required compression width of the material. Then, the bidirectional lead screw 71 is stopped, and the position between the clamping plates 73 is fixed, thereby controlling the width of the material thinning.

[0038] like Figure 9 As shown, it also includes a scraping mechanism 8. The scraping mechanism 8 is installed on the frame 1 at the third roller 41 and the fourth roller 42. The scraping mechanism 8 includes a first scraper 81 and a second scraper 82. The first scraper 81 and the second scraper 82 are both rotatably mounted on the frame 1 by torsion springs. The side of the first scraper 81 contacts the surface of the third roller 41, and the side of the second scraper 82 contacts the surface of the fourth roller 42. During the rotation of the third roller 41 and the fourth roller 42, the first scraper 81 and the second scraper 82 can scrape off the residue on the third roller 41 and the fourth roller 42 and let it fall down onto the first thinning mechanism 2 for the next thinning.

[0039] like Figure 10As shown, it also includes a cutting mechanism 9. The cutting mechanism 9 is installed on the frame 1 on the side of the first roller 21. The cutting mechanism 9 includes a cylinder 91, a second guide rail 92, a reciprocating screw 93, a cutter 94, a limit switch 95, and a roller 96. Cylinders 91 are bolted to the frame 1 at both ends of the first roller 21. The output ends of the cylinders 91 are connected to the second guide rail 92. The reciprocating screw 93 is rotatably connected to the second guide rail 92. The cutter 94 is connected to the reciprocating screw 93. Limit switches 95 are provided at both ends of the second guide rail 92. The limit switches 95 are linearly connected to the cylinders 91. Both ends of the rod 93 are connected to rollers 96. When it is necessary to cut the material on the first roller 21, the control cylinder 91 extends to drive the second guide rail 92 and its components to approach the first roller 21. After the cutter 94 contacts the first roller 21, the rollers 96 also contact the first roller 21. The rollers 96 rotate under the action of the first roller 21, causing the reciprocating screw 93 to rotate, driving the cutter 94 to move horizontally to cut the material. When the cutter 94 contacts the limit switch 95, the cylinder 91 retracts to drive the second guide rail 92 and its components to reset, and the cutter 94 and rollers 96 disengage from the first roller 21.

[0040] like Figure 1 and Figure 2 As shown, it also includes a collection frame 10. The collection frame 10 is provided on the frame 1 at the lower part of the first thinning mechanism 2 for collecting materials that fall from the first thinning mechanism 2.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
