Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0023] Please also read Figures 1 to 4The rubber coil trimming device provided by the utility model is now described. The rubber coil 20 deflection correction and trimming mechanism 30 comprises a frame 10, a trimming mechanism 30, a deflection correction mechanism 40, a refrigeration unit 50 and a winding mechanism 60. A placing roller 11 for placing the rubber coil 20 is provided on the frame 10; the trimming mechanism 30 is arranged at an interval with the placing roller 11, and the trimming mechanism 30 has two trimming output ends, which are respectively used to cut the two side edges of the rubber coil 20; the deviation correction mechanism 40 is arranged on the frame 10 and is located between the trimming mechanism 30 and the placing roller 11, and the deviation correction mechanism 40 is used to guide the unfolded rubber coil 20 to maintain a straight line; the refrigeration component 50 is arranged on the frame 10 and is located between the trimming mechanism 30 and the placing roller 11, and the refrigeration component 50 is used to cool the rubber coil 20; the winding mechanism 60 is arranged on the side of the trimming mechanism 30 away from the placing roller 11, and is used to wind the rubber coil 20 after trimming, and pull the rubber coil 20 to unwind on the placing roller 11.
[0024] The working process of a rubber coil trimming device provided by the utility model is as follows: the rubber coil 20 in the initial stage of forming is wound on the placing roller 11 on the frame 10, and the rubber coil 20 is unwound under the traction of the winding mechanism 60; during the unwinding process, the deviation correction mechanism 40 corrects the deviation of the rubber coil 20 that has been offset; the refrigeration component 50 cools the rubber coil 20 that has passed through the limiting component 43, and specifically, the refrigeration component 50 can be a low-temperature circulation machine, which performs heat exchange with the inside of the device to reduce the surface temperature of the rubber coil 20; the rubber coil 20 passes through the trimming mechanism 30, and the two trimming output ends trim the edges of the rubber coil 20 on both sides, and then the unwound rubber coil 20 is wound by the winding mechanism 60 to complete the winding.
[0025] The beneficial effect of the rubber coil trimming device provided by the utility model is that, compared with the prior art, by arranging the deviation correction mechanism 40 before the trimming mechanism 30, it can ensure that the rubber coil 20 always passes through the trimming mechanism 30 in a straight line at the target position, avoiding the rubber coil 20 from running off and affecting the trimming neatness, which is beneficial to improving the trimming quality of the rubber coil 20; at the same time, by using the refrigeration component 50, the rubber coil 20 with a high temperature in the initial molding stage can be cooled, avoiding the knife sticking phenomenon during the cutting process, improving the work efficiency, and trimming the rubber coil 20 after cooling can improve the edge neatness and smoothness, avoid the generation of burrs, and further improve the trimming quality of the rubber coil 20.
[0026] In one possible implementation, see Figure 2The deviation correction mechanism 40 includes a driving roller 41, a pressure roller 42, a limiting assembly 43, a driving motor 44 and two rotating driving members 45. The driving roller 41 is connected to the frame 10 and is used to roll and support the rubber coil 20; the pressure roller 42 is arranged on the frame 10 and is located directly above the driving roller 41. Two rollers 421 are arranged on the pressure roller 42 at intervals. The two rollers 421 roll the edges of the rubber coil 20 on both sides respectively; the limiting assembly 43 is arranged on the frame 10 and is located between the driving roller 41 and the trimming mechanism 30. The limiting assembly 43 has two limiting plates 431 that are distributed at intervals. A space suitable for the rubber coil 20 to pass through is formed between the two limiting plates 431; the driving motor 44 is arranged on the frame 10 and the output end is connected to the driving roller 41; the two rotating driving members 45 are arranged on the frame 10, and the output ends of the two rotating driving members 45 are respectively connected to the two rollers 421.
[0027] It should be noted that the driving motor 44 provides power to the driving roller 41, so that the rubber coil 20 can obtain the power to be transported forward when being pressed. The pressure roller 42 is located above the driving roller 41, and the roller 421 on the pressure roller 42 can press the rubber coil 20 against the driving roller 41. If the rubber coil 20 deviates to one side, the rotating driving member 45 on the same side is started to drive the roller 421 on the side to accelerate the rolling, and the speed difference on both sides of the rubber coil 20 is used to make the rubber coil 20 return to its original position. Two spaced-apart limiting plates 431 can allow the rubber coil 20 to always pass through the trimming mechanism 30 in a fixed position in a straight line to ensure the trimming neatness.
[0028] For some examples, see Figure 2 The limiting assembly 43 includes a limiting roller 432 and two limiting plates 431. The limiting roller 432 is arranged on the frame 10 and rolls on the upper surface of the rubber coil 20; the two limiting plates 431 are respectively rotatably connected to the limiting roller 432, and both have the freedom to slide along the axial direction of the limiting roller 432.
[0029] It should be noted that, in the process of the rubber coil 20 being conveyed from the driving roller 41 to the trimming mechanism 30, the limiting roller 432 increases the force acting on the upper surface of the rubber coil 20, making the conveying process of the rubber coil 20 more stable. The limiting plates 431 are slidably arranged on the limiting rollers 432, and the spacing between the limiting plates 431 can be adjusted according to the rubber coil 20 of different sizes, so as to constrain the position of the rubber coil 20 and improve the applicability of the equipment.
[0030] For some examples, see Figure 2 The limiting roller 432 is a hollow roller, and the output end of the refrigeration component 50 is connected to the limiting roller 432 for circulating the refrigerant into the limiting roller 432 .
[0031] It should be noted that the limiting roller 432 is a hollow thin-walled structure, and the refrigerant can be cooling water or cold air. The refrigeration component 50 inputs the refrigerant from one end of the limiting roller 432 and discharges it from the other end to realize the circulation of the refrigerant in the limiting roller 432, so that the limiting roller 432 and the refrigerant can exchange heat efficiently, and the surface temperature of the limiting roller 432 can be reduced. When the rubber coil 20 passes through the limiting roller 432, the rubber coil 20 will be cooled by the limiting roller 432 with a low-temperature outer surface. The cooled rubber coil 20 is not easy to stick to the knife when being cut, and the rubber coil 20 is not easy to have rough edges on both sides after cutting.
[0032] In one possible implementation, see Figure 3 A guide rail 46 extending along the axial direction of the limiting roller 432 is provided on the frame 10 or the trimming mechanism 30 , and the two limiting plates 431 are both slidably connected to the guide rail 46 .
[0033] It should be noted that both limit plates 431 contain self-locking switches. When the operator needs to fix the limit plates 431 that are slidably connected to a certain position on the guide rail 46 according to the specifications of the rubber coil 20, he presses the self-locking switch to fix the limit plates 431 on the guide rail 46. The guide rail 46 is located directly below the two limit plates 431, so that the two limit plates 431 can slide on the guide rail 46, thereby changing the relative distance between the two limit plates 431. The limit plates 431 are connected to the frame 10 or the trimming mechanism 30 through the guide rail 46, which increases the connection strength of the limit plates 431. The limit plates 431 can be fixed vertically on the overall device and will not rotate with the rolling of the limit rollers 432.
[0034] In one possible implementation, see Figure 3 The trimming mechanism 30 includes a trimming frame 31, a trimming shaft 32 and a trimming drive 34. The trimming frame 31 is provided with a conveying roller 311 for conveying the rubber coil 20; the trimming shaft 32 is provided on the frame 10 and is located above the conveying roller 311, and two circular cutters 33 are spaced apart along the axial direction of the trimming shaft 32, and each circular cutter 33 forms a trimming output end; the trimming drive 34 is fixedly provided on the trimming frame 31, and the output end of the trimming drive 34 is connected to the trimming shaft 32.
[0035] It should be noted that the circular cutter 33 performs rotary cutting on the rubber coil 20. The circular cutter 33 can adjust the axial position on the trimming shaft 32, and can perform trimming of different sizes on the rubber coil 20 according to production requirements. The trimming shaft 32 is connected to both sides with a trimming drive 34, which drives the circular cutter 33 to rotate and trim the rubber coil 20.
[0036] For some examples, see Figure 3The trimming frame 31 is provided with two rubber wheels 35 , the two rubber wheels 35 are located between the circular cutter 33 and the deviation correction mechanism 40 , and the two rubber wheels 35 are used to roll the edges of the rubber coil 20 on both sides.
[0037] It should be noted that the rubber wheel 35 presses the rubber coil 20 against the conveying roller 311. The rubber wheel 35 is located in front of the circular cutter 33. Before the circular cutter 33 trims the rubber coil 20, the rubber coil 20 is pressed against the conveying roller 311 to prevent the rubber coil 20 from warping and affecting the trimming quality, so that the trimming process proceeds smoothly and ensures that the two sides of the rubber coil 20 remain flush after trimming.
[0038] In one possible implementation, see Figure 3 Two recovery boxes 36 are provided on the trimming frame 31 , and the two recovery boxes 36 are respectively located directly below the two circular cutting knives 33 .
[0039] It should be noted that in order to prevent the cut rubber coil 20 waste from being discarded at the bottom of the device, a recovery box 36 for holding the cut waste is provided below the two circular cutters 33, and a door is provided on the side of the recovery box 36 for taking out the waste, so as to avoid safety hazards caused by approaching the circular cutters 33 when taking out the waste through the opening above the recovery box 36.
[0040] In one possible implementation, see Figure 4 The winding mechanism 60 includes a winding frame 61 and a winding roller 62. The winding roller 62 is rotatably connected to the winding frame 61 and parallel to the conveying roller 311, and is used to wind the trimmed rubber coil 20; wherein the winding roller 62 is drivingly connected to the trimming shaft 32 or the conveying roller 311.
[0041] It should be noted that the reel 62 automatically reels the rubber coil 20, and the trimming shaft 32 or the conveying roller 311 is in transmission connection with the reel 62, driving the reel 62 to roll and reel, thereby saving the subsequent manual reeling operation and labor.
[0042] In one possible implementation, see Figures 1 to 4 At least one end of the winding roller 62 is sleeved with a first transmission wheel 70 , and at least one end of the trimming shaft 32 is sleeved with a second transmission wheel 80 . The second transmission wheel 80 is connected to the first transmission wheel 70 through a conveyor belt 90 .
[0043] It should be noted that the second transmission wheels 80 are sleeved on both ends of the trimming shaft 32, the first transmission wheel 70 and the second transmission wheel 80 are connected by a conveyor belt 90, and the trimming drive 34 provides power for the trimming shaft 32. The second transmission wheel 80 on the trimming shaft 32 drives the first transmission wheel 70 to rotate through the conveyor belt 90, so as to achieve the purpose of the reeling mechanism 60 to reel the rubber coil 20, and at the same time, it can also provide traction to the rubber coil 20, so that the rubber coil 20 drives the placement roller 11 to rotate automatically and unwind, which is conducive to improving the synchronization of reeling and unwinding of the rubber coil 20. The structure composed of the first transmission wheel 70, the second transmission wheel 80 and the conveyor belt 90 makes it unnecessary to configure a power device on the reeling mechanism 60, thereby improving the utilization rate of the trimming drive 34.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
