[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 7This embodiment provides a double-head coating machine, including a processing support 1, a conveying device 2, a limiting and diverting device 3, a transfer device 4, a first processing device 5, and a second processing device 6. The processing support 1 is sequentially provided with a first discharge port 11, a first processing area 12, a feed port 13, a second processing area 14, and a second discharge port 15. The conveying device 2 is connected to the feed port 13 to convey materials to the feed port 13. The limiting and diverting device 3 includes a first limiting mechanism 31 and a second limiting mechanism 32, which are parallel to each other on both sides of the conveying device 2 along the feeding direction and can respectively enter or exit one side of the feed port 13 along the feeding direction to limit and divert the materials. The transfer device 4 is located on one side of the processing support 1 to transfer materials from the feed port 13 to the first processing area 12 or from the feed port 13 to the second processing area 14. The first processing device 5 includes a first spinning mechanism 51 and a first coating mechanism 52. The first spinning mechanism 51 is disposed on the first processing area 12 to drive the material to rotate, and the first coating mechanism 52 is disposed on one side of the first processing area 12 to wrap and attach the tape to the outer surface of the material when the material rotates. The second processing device 6 includes a second spinning mechanism 61 and a second coating mechanism 62. The second spinning mechanism 61 is disposed on the second processing area 14 to drive the material to rotate, and the second coating mechanism 62 is disposed on one side of the second processing area 14 to wrap and attach the tape to the outer surface of the material when the material rotates. During production, the material is conveyed to the feed inlet 13 by the conveying device 2, and then the material is diverted and limited by the limiting and diverting device 3. The material is then transferred to the first processing area 12 or the second processing area 14 by the transfer device 4. In the first processing area 12, the material is subjected to standardized coating processing by the first processing device 5, and in the second processing area 14, the material is subjected to standardized coating processing by the second processing device 6. The mechanical automation level is high, the production efficiency is high, and the coating quality is guaranteed.

[0026] Further, the conveying device 2 includes a first conveyor belt 21, which is provided with a unified conveying section 211, a transition conveying section 212, and a sequential conveying section 213 along the feeding direction. The unified conveying section 211 is provided with two parallel and opposite first conveying limiting plates 22, the sequential conveying section 213 is provided with two parallel and opposite second conveying limiting plates 23, and the transition conveying section 212 is provided with two conveying guiding mechanisms 24. Each conveying guiding mechanism 24 is connected at both ends to the adjacent first conveying limiting plate 22 and the second conveying limiting plate 23. Plate 23, the conveying and guiding mechanism 24 includes a first conveying wheel 241, a second conveying wheel 242, a conveying and guiding belt 243 connecting the first conveying wheel 241 and the second conveying wheel 242, and a conveying and guiding drive member 244 for driving the first conveying wheel 241 to rotate. The rotation shafts of the first conveying wheel 241 and the second conveying wheel 242 are perpendicular to the first conveying belt 21, so that the conveying and guiding belt 243 can drive the material from the side of the material to move from the first conveying limiting plate 22 to the second conveying limiting plate 23.

[0027] Specifically, the conveying and guiding drive component 244 is a motor, the output of which is connected to the first conveying wheel 241. When the conveying and guiding drive component 244 drives the first conveying wheel 241 to rotate, the second conveying wheel 242 is driven to rotate synchronously through the conveying guide belt 243. During production, a large batch of materials are uniformly placed into the unified conveying section 211. Under the conveying action of the first conveyor belt 21 and the limiting action of the first conveying limit plate 22, the materials move towards the transition conveying section 212. When passing through the transition conveying section 212, the materials located at the edge move towards the middle of the first conveyor belt 21 under the lateral force provided by the conveying and guiding mechanism 24, and move towards the sequential conveying section 213 under the conveying action of the first conveyor belt 21. When the materials enter the sequential conveying section 213 one by one, under the conveying action of the first conveyor belt 21 and the limiting action of the second conveying limit plate 23, they move steadily and sequentially towards the feed inlet 13. The distance between the two second conveying limit plates 23 is greater than the diameter of one material and less than the diameter of two materials, so that the materials can enter the conveying section 213 one by one and be conveyed along the conveying section 213 one by one.

[0028] Furthermore, the conveying device 2 also includes a second conveyor belt 25 disposed between the first conveyor belt 21 and the feed inlet 13. The width of the second conveyor belt 25 is smaller than the width of the first conveyor belt 21. The second conveyor belt 25 is provided with two parallel and opposite third conveying limiting plates 26. The limiting and diverting device 3 is disposed on the second conveyor belt 25 at one end near the feed inlet 13.

[0029] Specifically, the distance between the two third conveying limit plates 26 is equal to the distance between the two second conveying limit plates 23, and the distance between the first limiting mechanism 31 and the second limiting mechanism 32 is equal to the distance between the two third conveying limit plates 26. When the material enters the second conveyor belt 25 from the sequential conveying section 213 of the first conveyor belt 21, it continues to be conveyed sequentially to the feed inlet 13 under the limiting action of the third conveying limit plates 26.

[0030] Furthermore, the width of the second conveyor belt 25 is smaller than that of the first conveyor belt 21, resulting in a compact structure that effectively avoids unnecessary space occupation and achieves high space utilization. Moreover, the second conveyor belt 25 and the first conveyor belt 21 are driven independently by motors, and each of the second conveyor belt 25 and the first conveyor belt 21 is equipped with a counting sensor. The second conveyor belt 25 or the first conveyor belt 21 can be started or stopped based on the material quantity signal detected by the sensor, ensuring that the material is stably and sequentially supplied to the feed inlet 13 to meet production needs.

[0031] In addition, compared to the method where the first processing area 12 and the second processing area 14 each use a separate conveying device 2, this embodiment can simultaneously provide materials to the first processing area 12 and the second processing area 14 with a single conveying device 2. This results in a more compact structure, less space occupation, and a significant reduction in the cost of the conveying device 2.

[0032] Furthermore, the first limiting mechanism 31 includes a first limiting member 311 and a first limiting drive member 312. The first limiting member 311 extends along the feeding direction, and the first limiting drive member 312 is connected to the first limiting member 311 to drive the first limiting member 311 to enter or exit one side of the feed inlet 13 along the feeding direction. The second limiting mechanism 32 includes a second limiting member 321 and a second limiting drive member 322. The second limiting member 321 extends along the feeding direction, and the second limiting drive member 322 is connected to the second limiting member 321 to drive the second limiting member 321 to enter or exit the other side of the feed inlet 13 along the feeding direction.

[0033] Specifically, in this embodiment, the first limiting mechanism 31 is located on the side close to the first processing area 12, and the second limiting mechanism 32 is located on the side close to the second processing area 14.

[0034] When the first limiting drive member 312 drives the first limiting member 311 into one side of the feed inlet 13, and the second limiting drive member 322 drives the second limiting member 321 into the feed inlet 13, since the first limiting member 311 and the second limiting member 312 are simultaneously blocked on both sides of the feed inlet 13, the material can be effectively restricted from moving towards the first processing area 12 or towards the second processing area 14, ensuring that the material smoothly enters the feed inlet 13 from the conveying device 2 along the conveying direction.

[0035] When the first limiting drive member 312 drives the first limiting member 311 to enter the feed port 13 side, and the second limiting drive member 322 drives the second limiting member 321 to exit the feed port 13 side, the feed port 13 is limited and blocked by the first limiting member 311 on the side close to the first processing area 12, which can effectively restrict the material from moving towards the first processing area 12. At the same time, since the feed port 13 is not limited and blocked on the side close to the second processing area 14, the material can be driven to move towards the second processing area 14.

[0036] When the first limiting drive member 312 drives the first limiting member 311 to exit the feed port 13 side, and the second limiting drive member 322 drives the second limiting member 321 to enter the feed port 13 side, the feed port 13 is blocked by the second limiting member 321 on the side near the second processing area 14, which can effectively restrict the material from moving towards the second processing area 14. At the same time, since the feed port 13 is not blocked on the side near the first processing area 12, the material can be driven to move towards the first processing area 12.

[0037] Preferably, in this embodiment, both the first limiting drive member 312 and the second limiting drive member 322 are cylinders. The piston rod in the cylinder moves to move the first limiting member 311 and the second limiting member 321. By independently controlling the movement of the first limiting member 311 and the second limiting drive member 322, the movement of the first limiting member 311 and the second limiting member 321 is effectively limited and the material is diverted to the first processing area 12 and the second processing area 14.

[0038] Further, the transfer device 4 includes a first transfer mechanism 41, a second transfer mechanism 42, and a third transfer mechanism 43. The first transfer mechanism 41 includes a first transfer arm 411 and a first transfer drive member 412 connected to the first transfer arm 411. The first transfer arm 411 is provided with a plurality of first transfer grooves 4111 that cooperate with the material. The first transfer drive member 412 drives the first transfer arm 411 to move closer to or away from the processing bracket 1 from one side, so that the first transfer arm 411 clamps or releases the material from the material side. The second transfer mechanism 42 includes a second transfer arm 421 and a second transfer drive member 422 connected to the second transfer arm 421. The arm 421 is provided with a plurality of second transfer grooves 4211 that cooperate with the material. The second transfer drive member 422 drives the second transfer arm 421 to move closer to or away from the processing bracket 1 from one side, so that the second transfer arm 421 clamps or releases the material from the material side. The third transfer mechanism 43 connects the first transfer mechanism 41 and the second transfer mechanism 42, and is used to drive the first transfer mechanism 41 and the second transfer mechanism 42 to move back and forth synchronously along the length direction of the processing bracket 1, so that the first transfer mechanism 41 carries the material from the feed port 13 to the first processing area 12, or the second transfer mechanism 42 carries the material from the feed port 13 to the second processing area 14.

[0039] Specifically, when the third transfer mechanism 43 drives the first transfer mechanism 41 and the second transfer mechanism 42 to move synchronously from the first transfer groove 4111 on the first transfer mechanism 41 to the feed inlet 13, the first limiting mechanism 31 and the second limiting mechanism 32 cooperate to allow the material to be moved towards the first processing area 12. The first transfer drive member 412 in the first transfer mechanism 41 drives the first transfer arm 411 to approach the processing bracket 1 from one side of the processing bracket 1, so that the first transfer groove 4111 cooperates with the material, thereby enabling the first transfer... The feeding arm 411 clamps the material from one side of the material. Then, the third transfer mechanism 43 drives the first transfer mechanism 41 and the second transfer mechanism 42 to move synchronously toward the first processing area 12, so that the first transfer arm 411 carries the material from the feed port 13 to the first processing area 12. Then, the first transfer drive 412 drives the first transfer arm 411 away from the processing support 1 from one side of the processing support 1, so that the first transfer groove 4111 is disengaged from the material, thereby releasing the material from the material side of the first transfer arm 411 for subsequent processing.

[0040] Similarly, when the third transfer mechanism 43 drives the first transfer mechanism 41 and the second transfer mechanism 42 to move synchronously from the second transfer groove 4211 on the second transfer mechanism 42 to the inlet 13, the first limiting mechanism 31 and the second limiting mechanism 32 cooperate to allow the material to be moved towards the second processing area 14. Then, the second transfer drive member 422 in the second transfer mechanism 42 drives the second transfer arm 421 to approach the processing support 1 from one side of the processing support 1, so that the second transfer groove 4211 cooperates with the material, thereby enabling the second transfer... The feeding arm 421 clamps the material from one side. Then, the third transfer mechanism 43 drives the first transfer mechanism 41 and the second transfer mechanism 42 to move synchronously toward the second processing area 14, so that the second transfer arm 421 carries the material from the feed port 13 to the second processing area 14. Then, the second transfer drive 422 drives the second transfer arm 421 away from the processing support 1 from one side, so that the second transfer groove 4211 is disengaged from the material, thereby releasing the material from the material side for subsequent processing.

[0041] In this embodiment, the transfer device 4, through the orderly cooperation of the first transfer mechanism 41, the second transfer mechanism 42 and the third transfer mechanism 43, can efficiently and orderly transfer materials from the feed inlet 13 to the first processing area 12 or from the feed inlet 13 to the second processing area 14.

[0042] Furthermore, the first processing device 5 also includes a first flattening mechanism 53, which is located on one side of the first processing area 12 to flatten the end of the tape after the material is coated. The second processing device 6 also includes a second flattening mechanism 63, which is located on one side of the second processing area 14 to flatten the end of the tape after the material is coated. By flattening the end of the tape using the first flattening mechanism 53 and the second flattening mechanism 63, the coating can be more tightly adhered, more secure, and less prone to curling.

[0043] Furthermore, the first processing area 12 is provided with a first waiting station 121, a first coating station 122, and a first flattening station 123 in sequence from the inlet 13 to the outlet 11. The first coating station 122 and the first flattening station 123 are both provided with the first spinning mechanism 51. The first coating station 122 is provided with the first coating mechanism 52 on one side, and the first flattening station 123 is provided with the first flattening mechanism 53 on one side. The second processing area 14 is provided with a second waiting station 141, a second coating station 142, and a second flattening station 143 in sequence from the inlet 13 to the outlet 15. The second coating station 142 and the second flattening station 143 are both provided with the second spinning mechanism 61. The second coating station 142 is provided with the second coating mechanism 62 on one side, and the second flattening station 143 is provided with the second flattening mechanism 63 on one side.

[0044] Specifically, the first transfer arm 411 of the first transfer mechanism 41 is provided with three first transfer slots 4111. When the third transfer mechanism 43 drives the first transfer mechanism 41 and the second transfer mechanism 42 to move synchronously toward the first processing area 12 for the first time, the first transfer slot 4111 on the first transfer arm 411 closest to the second transfer mechanism 42 moves the first material from the feed inlet 13 to the first waiting station 121. When the third transfer mechanism 43 drives the first transfer mechanism 41 and the second transfer mechanism 42 to move synchronously toward the first processing area 12 for the second time, the first transfer slot 4111 on the first transfer arm 411 closest to the second transfer mechanism 42 moves the second material from the feed inlet 13 to the first waiting station 12. 1. Simultaneously, the first transfer groove 4111 located in the middle of the first transfer arm 411 moves the first material from the first waiting station 121 to the first coating station 122. The first spinning mechanism 51 drives the first material to rotate, and the first coating mechanism 52 performs coating processing on the first material. When the third transfer mechanism 43 drives the first transfer mechanism 41 and the second transfer mechanism 42 to move synchronously towards the first processing area 12 for the third time, the first transfer groove 4111 on the first transfer arm 411 closest to the second transfer mechanism 42 moves the third material from the feed port 13 to the first waiting station 121. At the same time, the first transfer groove 4111 located in the middle of the first transfer arm 411 moves the second material from the first waiting station 121 to the first waiting station 122. 1. The material moves to the first coating station 122, where the first spinning mechanism 51 drives the second material to rotate, and the first coating mechanism 52 performs coating processing on the second material. Simultaneously, the first transfer groove 4111 on the first transfer arm 411, located furthest from the second transfer mechanism 42, moves the first material to the first flattening station 123, where the first spinning mechanism 51 drives the first material to rotate, and the first flattening mechanism 53 performs flattening processing on the first material. When the third transfer mechanism 43 drives the first transfer mechanism 41 and the second transfer mechanism 42 to move synchronously towards the first processing area 12 for the fourth time, the first transfer groove 4111 on the first transfer arm 411, closest to the second transfer mechanism 42, moves the fourth material from the feed inlet 13. The material moves to the first waiting station 121. Simultaneously, the first transfer trough 4111 on the first transfer arm 411, located in the middle, moves the third material from the first waiting station 121 to the first coating station 122. The first spinning mechanism 51 rotates the third material, and the first coating mechanism 52 performs coating processing on the third material. At the same time, the first transfer trough 4111 on the first transfer arm 411, located furthest from the second transfer mechanism 42, moves the second material to the first flattening station 123. The first spinning mechanism 51 rotates the second material, and the first flattening mechanism 53 performs flattening processing on the second material. Simultaneously, the edge of the first transfer arm 411 furthest from the second transfer mechanism 42 pushes the first material to the first discharge port 11. The mechanisms work together in an orderly manner, resulting in high work efficiency.

[0045] Similarly, the working principle and motion relationship between the second transfer mechanism 42 and the second material waiting station 141, the second rubber coating station 142, the second flattening station 143, the second spinning mechanism 61, the second rubber coating mechanism 62 and the second flattening mechanism 63 in the second processing area 14 are the same and will not be described again.

[0046] Furthermore, both the first spinning mechanism 51 and the second spinning mechanism 61 include a rotating support 511, a rotating drive 512, a positioning pressure shaft 513, and a pressure shaft drive 514. The rotating support 511 is disposed on the processing bracket 1. The rotating drive 512 is connected to the rotating support 511 to drive the rotating support 511 to rotate the material. The positioning pressure shaft 513 is disposed above the rotating support 511. The pressure shaft drive 514 is connected to the positioning pressure shaft 513 to drive the positioning pressure shaft 513 closer to the rotating support 511 to position and press the material onto the rotating support 511, or to drive the positioning pressure shaft 513 away from the rotating support 511 to release the material. When the material is placed at the first coating station 122, the first leveling station 123, the second coating station 142, or the second leveling station 143, the pressure shaft drive 514 drives the positioning pressure shaft 513 to approach and press the material onto the rotating support 511. Subsequently, the rotation drive 512 drives the rotating support 511 to rotate, thereby causing the material to rotate. After the coating or leveling operation is completed, the rotation drive 512 drives the rotating support 511 to stop the material from rotating, and the pressure shaft drive 514 drives the positioning pressure shaft 513 away from the material, thereby releasing the material so that it can be moved to the next process. Preferably, in this embodiment, the pressure shaft drive 514 is a cylinder, and the rotation drive 512 is a motor.

[0047] Furthermore, both the first coating mechanism 52 and the second coating mechanism 62 include a guide roller 521, an arc-shaped guide plate 522, a pressure roller 523, a pressure roller seat 524, a pressure roller drive 525, a cutter 526, a cutter seat 527, and a cutter drive 528. The pressure roller 523 is disposed on the pressure roller seat 524, and the guide roller 521 and the arc-shaped guide plate 522 are disposed on one side of the pressure roller seat 524. The pressure roller drive 525 is connected to the pressure roller seat 524 to drive the pressure roller seat 524 to move the pressure roller 523 closer to or away from the material. The cutter 526 is disposed on the cutter seat 527, and the cutter seat 527 is connected to the pressure roller seat 524. The cutter drive 528 is connected to the cutter seat 527 to drive the cutter seat 527 to rotate the cutter 526 relative to the pressure roller seat 524, thereby cutting the tape. The tape is guided to the front end of the pressure roller 523 via the guide roller 521 and the arc-shaped guide plate 522. When it is necessary to coat the material with tape, the pressure roller drive 525 drives the pressure roller seat 524 to move the pressure roller 523 closer to the material, so that one end of the tape adheres to the material. When the material rotates under the drive of the first spinning mechanism 51 or the second spinning mechanism 61, the tape continues to wrap around and adhere to the outer surface of the material. Subsequently, the cutter drive 528 drives the cutter seat 527 to rotate the cutter 526 relative to the pressure roller seat 524, thereby cutting the tape. Then, the cutter drive 528 drives the cutter seat 527 to rotate the cutter 526 in the opposite direction relative to the pressure roller seat 524 to reset. The pressure roller drive 525 drives the pressure roller seat 524 to move the pressure roller 523 away from the material to reset. Preferably, in this embodiment, both the cutter drive 528 and the pressure roller drive 525 are cylinders.

[0048] Furthermore, both the first flattening mechanism 53 and the second flattening mechanism 63 include an elastic pressure plate 531 and a flattening drive member 532 for driving the elastic pressure plate 531 closer to or away from the material. One end of the elastic pressure plate 531 is connected to the flattening drive member 532, and the other end has a rebound space between it and the flattening drive member 532. When the material is placed into the first flattening station 123 or the second flattening station 143, the flattening drive member 532 drives the elastic pressure plate 531 closer to the material to apply pressure to the circumference of the rotating material, which can effectively press the end of the tape and improve the coating quality.

[0050] The above description is the preferred embodiment of this utility model.
