[0004] However, when the silicone product is conveyed above by this kind of silicone pressure roller, air bubbles are likely to be generated between the silicone product and the pressure roller. If the air bubbles are not removed, it is easy to cause uneven pressure during the extrusion process of the silicone product, resulting in problems with the product. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a pressure roller structure of silicone processing equipment to solve the problem that when the silicone product is conveyed above by the silicone pressure roller in the prior art, air bubbles are likely to be generated between the silicone product and the pressure roller. If the air bubbles are not removed, it is easy to cause uneven pressure during the extrusion process of the silicone product, resulting in problems with the product.

[0006] The purpose and effect of a pressure roller structure of silicone processing equipment of the utility model are achieved by the following specific technical means: a pressure roller structure of silicone processing equipment includes a frame, a mounting frame, and a pressure roller. The mounting frame is fixedly connected above the frame. The pressure roller is arranged on one side of the mounting frame. A feeding roller is rotatably connected above the frame. An installation cavity is opened on the inner wall of the frame. A fixed frame corresponding to the installation cavity is fixedly connected above the frame. An output roller is rotatably connected on the right side of the frame.

[0007] Preferably, two upper and lower pressing rollers are arranged correspondingly, and a sliding frame located in the mounting frame is rotatably connected to the side end of the upper pressing roller.

[0008] Preferably, an adjusting screw rod is threadedly connected above the mounting frame, and the sliding frame is threadedly connected to the adjusting screw rod.

[0009] Preferably, a bevel gear is fixedly connected to one side of the feeding roller and located in the mounting cavity. A transmission rod is meshed with the side of the bevel gear.

[0010] Preferably, a sliding sleeve is threadedly connected to the reciprocating lead screw rod. A tensioning roller is rotatably connected to one side of the sliding sleeve. One side of the tensioning roller penetrates through the side wall of the fixing frame.

[0011] Preferably, a plurality of mounting cavities are arranged in sequence. A push rod is fixedly connected to the side wall of the sliding sleeve on the rod of the reciprocating lead screw on the right side. An air bag located in the mounting cavity is fixedly installed at the side end of the push rod.

[0012] Preferably, an air guide port is arranged on one side of the discharging roller and located in the mounting cavity. An air outlet corresponding to the air guide port is arranged on the side wall of the air bag.

[0013] Preferably, a cavity corresponding to the air guide port is arranged inside the discharging roller, and air holes are arranged on the side wall of the cavity.

[0014] Beneficial effects:

[0015] 1. During the rotation of the bevel gear at one end of the feeding roller, the meshed transmission rod on the side will be driven to rotate in the mounting cavity. When the transmission rod rotates, the reciprocating lead screws meshed on the right side and above will be driven to rotate together. When the upper reciprocating lead screw rotates, the reciprocating lead screw will push the sliding sleeve threadedly connected to the rod to move up and down inside the fixing frame. When the sliding sleeve reciprocates up and down, it will drive the tensioning roller rotatably connected to the side end to move up and down. Thus, when the silicone product is transmitted between the pressing rollers for processing by the tensioning roller, the silicone product will be pushed up and down by the tensioning roller to stretch it. Therefore, when the silicone product is transmitted between the pressing rollers and extruded, no problems such as air bubbles are likely to occur between the silicone product and the pressing rollers, and the problem of uneven pressure will not occur during the extrusion of the silicone product, improving the yield of the silicone product.

[0016] 2. When driving the reciprocating screw rod on the right side to rotate through the transmission rod, the reciprocating screw rod on the right side will also push the sliding sleeve on the rod body to move. When the sliding sleeve moves, it will drive the push rod on the side to move together. During the left-right reciprocating movement of the push rod, the push rod will squeeze or stretch the airbag fixedly installed at the side end. After the airbag is squeezed, the airbag will be discharged into the installation cavity on the far right through the air outlet on the side. The air inlet at one end of the discharge roller is connected to the installation cavity, so that the air squeezed out inside the airbag will be transmitted to the cavity at the beginning inside the discharge roller. During the rotation of the discharge roller, the air is discharged from the air holes opened on the side wall. Therefore, when the discharge roller conveys and discharges the processed silicone product, the silicone product is not easily adhered to the upper part of the discharge roller, and the discharge of the silicone product is more efficient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0024] As shown in the attached Figure 1 to the attached Figure 4 figures:

[0025] A pressure roller structure of a silicone processing device, including a frame 1, a mounting frame 2 and a pressure roller 201. The mounting frame 2 is fixedly connected above the frame 1. The pressure roller 201 is rotatably connected to the side of the mounting frame 2, and a feeding roller 401 is rotatably connected above the frame 1. After the pressure roller 201 extrudes the silicone product, the feeding roller 401 will continuously transport it.

[0026] It should be understood that the above-mentioned fixed connection means that there is no relative movement between the two. There are various ways of fixed connection. Here, a bolt method can be used for fixation, making it more convenient to disassemble and maintain the pressure roller 201 later.

[0027] Since the pressure roller 201 is provided in two corresponding upper and lower parts, when the adjusting screw rod 301 threadedly connected above the mounting frame 2 is rotated, the adjusting screw rod 301 can push the carriage 3 threadedly connected to the rod body to slide on the inner wall of the mounting frame 2. The carriage 3 is clamped at both ends on the inner wall of the mounting frame 2, so that the carriage 3 will not rotate together with the adjusting screw rod 301. During the lifting process of the carriage 3, the pressure roller 201 rotatably connected to the side end will be driven to lift, and then the distance between the upper and lower pressure rollers 201 can be adjusted to facilitate the processing of silicone products of different sizes. When the feeding roller 401 rotates to transport the silicone product, one end of the feeding roller 401 penetrates into the installation cavity 4 starting from the side wall of the frame 1, so that the tapered gear 5 fixedly connected to one end of the feeding roller 401 will rotate in the installation cavity 4. During the rotation of the tapered gear 5, the transmission rod 402 meshed on the side will be driven to rotate in the installation cavity 4. When the transmission rod 402 rotates, the reciprocating screw rod 501 meshed on the right side and above will be driven to rotate together. When the upper reciprocating screw rod 501 rotates, the reciprocating screw rod 501 will push the sliding sleeve 502 threadedly connected to the rod body to lift and lower inside the fixed frame 6. The sliding sleeve 502 is limited in the limiting groove starting inside the fixed frame 6 by the clamping plates fixedly connected to both sides, so that the sliding sleeve 502 will not rotate together with the reciprocating screw rod 501. When the sliding sleeve 502 reciprocates up and down, it will drive the tension roller 601 rotatably connected to the side end to lift and lower. Then, when the tension roller 601 transports the silicone product between the pressure rollers 201 for processing, the silicone product will be pushed up and down by the tension roller 601 to stretch it. Thus, during the extrusion process of the silicone product between the pressure rollers 201, problems such as air bubbles are not likely to occur between the silicone product and the pressure roller 201, and the problem of uneven pressure will not occur during the extrusion process of the silicone product, improving the yield of the silicone product.

[0028] When the transmission rod 402 drives the reciprocating lead screw 501 on the right side to rotate, the reciprocating lead screw 501 on the right side will also push the sliding sleeve 502 threadedly connected to the rod body to move. The sliding sleeve 502 is fixedly connected to a push rod 7 penetrating into the right installation cavity 4 through both side walls. When the sliding sleeve 502 pushes the push rod 7 to move, the push rod 7 will also limit the sliding sleeve 502 to prevent the sliding sleeve 502 from rotating together with the reciprocating lead screw 501. During the left-right reciprocating movement of the push rod 7, the push rod 7 will squeeze or stretch the airbag 701 fixedly installed at the side end. After the airbag 701 is squeezed, the airbag 701 will be discharged into the rightmost installation cavity 4 through the air outlet on the side. The rightmost installation cavity 4 is rotatably connected to a discharge roller 8 at the side. The air guide port at one end of the discharge roller 8 communicates with the installation cavity 4, so that the air squeezed out inside the airbag 701 will be transmitted to the cavity 801 at the beginning inside the discharge roller 8. And when the push rod 7 returns to its original position, it will pull the airbag 701 to open. During the opening process of the airbag 701, the airbag 701 will inhale air through the air inlet opened on the side wall of the installation cavity 4. After the cavity 801 is filled with air, the discharge roller 8 will discharge the air from the air holes 802 opened on the side wall during the rotation process. Thus, when the discharge roller 8 conveys and discharges the processed silicone product, the silicone product is not easily adhered above the discharge roller 8, and the discharge of the silicone product is more efficient.

[0029] Working principle: When the feeding roller 401 transports the material to be processed between the pressing rollers 201, rotate the adjusting screw 301 above the mounting frame 2. The adjusting screw 301 will push the carriage 3 on the rod body to slide on the inner wall of the mounting frame 2. During the lifting and lowering process of the carriage 3, it will drive one of the upper pressing rollers 201 to lift and lower, so that the distance between the upper and lower pressing rollers 201 can be adjusted to facilitate the processing of silicone products of different sizes. When the feeding roller 401 rotates to transport the silicone product, the bevel gear 5 at one end of the feeding roller 401 will rotate in the installation cavity 4. During the rotation of the bevel gear 5, it will drive the transmission rod 402 meshed on the side to rotate in the installation cavity 4. When the transmission rod 402 rotates, it will drive the reciprocating screw rod 501 meshed on the right side and above to rotate together. When the upper reciprocating screw rod 501 rotates, the reciprocating screw rod 501 will push the sliding sleeve 502 on the rod body to lift and lower inside the fixed frame 6. When the sliding sleeve 502 reciprocates up and down, it will drive the tensioning roller 601 at the side end to lift and lower, so that the silicone product will be pushed up and down by the tensioning roller 601 to stretch it. Thus, when the silicone product is transported between the pressing rollers 201 and extruded, problems such as air bubbles are not likely to occur between the silicone product and the pressing rollers 201. When the transmission rod 402 drives the reciprocating screw rod 501 on the right side to rotate, the reciprocating screw rod 501 on the right side will also push the sliding sleeve 502 on the rod body to move. During the left and right reciprocating movement of the push rod 7, the push rod 7 will squeeze or stretch the airbag 701 at the side end. After the airbag 701 is squeezed, the airbag 701 will be discharged into the rightmost installation cavity 4 through the air outlet on the side. The air inside the installation cavity 4 will be transmitted to the cavity 801 inside the discharging roller 8 through the air guiding port. After the cavity 801 is filled with air, the discharging roller 8 will discharge the air from the air holes 802 on the side wall during rotation. Thus, when the discharging roller 8 transports and discharges the processed silicone product, the silicone product is not likely to adhere to the upper part of the discharging roller 8. And when the push rod 7 returns, it will pull the airbag 701 to open. During the opening process of the airbag 701, it will inhale air through the air inlet opened on the side wall of the installation cavity 4, so that the airbag 701 can be continuously used.
