Description

Technical Field

[0001] This utility model relates to the field of open mill technology, specifically to an open mill mechanism for silicone tube production. Background Technology

[0002] An open mill is short for an open-type rubber mixing mill. It is a type of rubber mixing machine with exposed rollers, typically used for preparing plasticized rubber, compounding rubber, or for hot refining and molding. Open mills are one of the earliest plastic mixing equipment used in plastic product manufacturing plants. When producing silicone tubes, the raw materials need to be processed, which requires the use of an open mill.

[0003] A silicone open mixing mill, with publication number CN219705744U, includes a frame, a front roller, and a rear roller. Both the front and rear rollers are fitted inside the frame, and a reduction gearbox associated with the rear roller is fixedly mounted on the outside of the frame. This silicone open mixing mill, through the coordinated use of a drive motor, a threaded rod, a sliding sleeve, and a cutting blade, allows the drive motor to start and rotate the threaded rod in the fixed frame via its drive shaft when a scoring operation is required on the silicone material. The threaded rod's external threads then push the sliding sleeve to slide within the movable cavity of the fixed frame, thereby driving the cutting blade to score the silicone material outside the front roller. This design ensures that the silicone open mixing mill does not occupy additional space outside the frame during scoring operations, thus reducing the space required for scoring silicone material while maintaining the mill's operational status.

[0004] The aforementioned disclosed technology has some defects in actual use. The patented technology uses two handwheels to drive the front roller to rotate, but there is no transmission connection between the two handwheels. This can easily lead to the two handwheels rotating out of sync during actual use, causing the front roller to move and deviate, affecting the normal operation of the device. At the same time, the aforementioned patented technology only uses the cooling pipe inside the cutting blade for cooling, and its cooling effect is also poor. Utility Model Content

[0005] The purpose of this invention is to provide a two-roll mill mechanism for silicone tube production, which solves the problems of asynchronous adjustment of the front roller and poor cooling effect in existing two-roll mills.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silicone tube production open milling mechanism, comprising a base plate, support plates fixedly connected to both sides of the top of the base plate, a fixed roller installed between the two support plates, an adjusting roller provided on one side of the fixed roller, sleeve pipes fixedly connected to both ends of the fixed roller and the adjusting roller, a support frame installed on the top of the support plate, and a transmission rod installed at the top of the base plate away from the fixed roller;

[0007] The support plate has rectangular holes at both ends near the adjusting roller. A slider is slidably connected inside the rectangular hole, and a lead screw is threaded inside the slider.

[0008] The sleeves at both ends of the adjusting roller are rotatably connected to the slider, and the sleeves at both ends of the fixed roller penetrate the interior of the support plate.

[0009] Both ends of the transmission rod are fixedly connected to the outer wall of the drive helical gear, and the side of the drive helical gear closest to the support plate is meshed with the driven helical gear.

[0010] Preferably, one end of each sleeve is rotatably connected to a bent pipe, and a spiral cooling pipe is arranged around the inside of both the fixed roller and the adjusting roller. The spiral cooling pipe is in contact with the inner wall of the fixed roller and the adjusting roller, and both ends of the spiral cooling pipe penetrate the inside of the sleeve and the bent pipe.

[0011] Preferably, one end of the bent pipe is bent toward one side of the base plate, and multiple cooling blades are installed on the inner walls of the fixed roller and the adjusting roller. The interiors of the fixed roller and the adjusting roller are connected to the bent pipe through sleeves.

[0012] Preferably, a rotating gear is fixedly connected to the outer wall of the sleeve at one end of the fixed roller, a drive gear is meshed with one side of the rotating gear, a drive motor is installed at the center of the drive gear, and the drive gear is rotatably connected to the outer wall of the support plate through a rotating shaft.

[0013] Preferably, one end of the lead screw is rotatably connected to the inside of the rectangular hole via a rotating shaft, and the end of the lead screw near the transmission rod passes through the rectangular hole and is fixedly connected to the driven helical gear.

[0014] Preferably, the top of the support frame has a strip-shaped hole, a movable block is slidably connected to the top of the support frame, a cutting plate is slidably connected to the center of the movable block, the cutting plate penetrates the interior of the cutting plate, a fixing bolt is threaded to one side of the movable block, and one end of the fixing bolt is attached to the outer wall of the cutting plate.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. Rotating the transmission rod causes the two driving helical gears to rotate, which in turn drives the driven helical gears to rotate, causing the two lead screws to rotate. This causes the slider to move synchronously inside the rectangular hole, which in turn facilitates the movement of the sleeves at both ends of the adjusting roller. This achieves synchronous movement of both ends of the adjusting roller, preventing skewing. Furthermore, the operation is more convenient as it only requires rotating the transmission rod.

[0017] 2. The corresponding cooling water is delivered to the spiral cooling pipes inside the fixed roller and the adjusting roller to cool them. At the same time, during use, cold air can be conveniently delivered to the bushing pipe through the fan via the bend pipe, and then delivered to the inside of the fixed roller and the adjusting roller through the bushing pipe. Since the fixed roller and the adjusting roller are equipped with multiple cooling blades, the cooling blades can be easily cooled, thereby improving the cooling efficiency of the fixed roller and the adjusting roller.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5The diagram shows an open milling mechanism for producing silicone tubes, comprising a base plate 1, with support plates 2 fixedly connected to both sides of the top of the base plate 1, a fixed roller 3 installed between the two support plates 2, an adjusting roller 301 provided on one side of the fixed roller 3, sleeves 4 fixedly connected to both ends of the fixed roller 3 and the adjusting roller 301, a support frame 5 installed on the top of the support plate 2, and a transmission rod 7 installed at the top of the base plate 1 away from the fixed roller 3; rectangular holes 201 are provided at both ends of the support plate 2 near the adjusting roller 301, sliders 202 are slidably connected inside the rectangular holes 201, and screw rods 203 are threadedly connected inside the sliders 202; the sleeves 4 at both ends of the adjusting roller 301 are rotatably connected to the sliders 202, and the sleeves 4 at both ends of the fixed roller 3 penetrate the interior of the support plate 2; a driving helical gear 701 is fixedly connected to the outer wall at both ends of the transmission rod 7, and a driven helical gear 702 is meshed with the side of the driving helical gear 701 near the support plate 2.

[0028] The cutting plate 502 can be easily moved along the strip hole 503 to cut the material, facilitating further mixing and processing. Simultaneously, the transmission rod 7 can be easily rotated according to processing requirements, causing the transmission rod 7 to rotate and drive the two active helical gears 701 to rotate. This, in turn, causes the active helical gears 701 to drive the driven helical gears 702 to rotate, which in turn causes the two lead screws 203 to rotate. This, in turn, causes the slider 202 to move synchronously within the rectangular hole 201, thus easily moving the sleeves 4 at both ends of the adjusting roller 301. This achieves synchronous movement of both ends of the adjusting roller 301, preventing skewing.

[0029] The corresponding cooling water is delivered to the spiral cooling pipe 303 inside the fixed roller 3 and the adjusting roller 301, thereby cooling the fixed roller 3 and the adjusting roller 301. At the same time, during use, cold air can be conveniently delivered to the sleeve pipe 4 through the bend pipe 401 by the fan, and then delivered to the interior of the fixed roller 3 and the adjusting roller 301 through the sleeve pipe 4. Since the fixed roller 3 and the adjusting roller 301 are equipped with multiple cooling blades 302, the cooling blades 302 can be easily cooled, thereby improving the cooling efficiency of the fixed roller 3 and the adjusting roller 301.

[0030] like Figure 1 , Figure 5As shown, one end of the sleeve 4 is rotatably connected to a bend 401. Both the fixed roller 3 and the adjusting roller 301 are surrounded by spiral cooling pipes 303. The spiral cooling pipes 303 are in contact with the inner walls of the fixed roller 3 and the adjusting roller 301. Both ends of the spiral cooling pipes 303 penetrate the sleeve 4 and the interior of the bend 401. One end of the bend 401 is bent towards one side of the base plate 1. Multiple cooling blades 302 are installed on the inner walls of the fixed roller 3 and the adjusting roller 301. The interiors of the fixed roller 3 and the adjusting roller 301 are connected by the sleeve 4. 4 is connected to the bend pipe 401, and the corresponding cooling water is transported to the spiral cooling pipe 303 inside the fixed roller 3 and the adjusting roller 301, thereby cooling the fixed roller 3 and the adjusting roller 301. At the same time, during use, cold air can be conveniently transported to the sleeve pipe 4 through the bend pipe 401 by the fan, and then transported to the inside of the fixed roller 3 and the adjusting roller 301 through the sleeve pipe 4. Since the fixed roller 3 and the adjusting roller 301 are equipped with multiple cooling blades 302, the cooling blades 302 can be conveniently cooled.

[0031] like Figure 2 , Figure 3 As shown, a rotating gear 6 is fixedly connected to the outer wall of the sleeve 4 at one end of the fixed roller 3. A drive gear 601 is meshed with one side of the rotating gear 6. A drive motor is installed at the center of the drive gear 601. The drive gear 601 is rotatably connected to the outer wall of the support plate 2 through a rotating shaft. When the drive motor is started, the drive gear 601 rotates, causing the rotating gear 6 to rotate, which in turn causes the sleeve 4 to rotate, thereby driving the fixed roller 3 to rotate.

[0032] like Figure 2 , Figure 3 As shown, one end of the lead screw 203 is rotatably connected to the inside of the rectangular hole 201 via a rotating shaft. The end of the lead screw 203 near the transmission rod 7 passes through the rectangular hole 201 and is fixedly connected to the driven helical gear 702. Rotating the transmission rod 7 causes the transmission rod 7 to rotate, thereby driving the two driving helical gears 701 to rotate, which in turn causes the driving helical gears 701 to rotate, and thus causes the two lead screws 203 to rotate.

[0033] like Figure 1 , Figure 3 As shown, the top of the support frame 5 has a strip-shaped hole 503. A moving block 501 is slidably connected to the top of the support frame 5. A cutting plate 502 is slidably connected to the center of the moving block 501. The cutting plate 502 penetrates the interior of the cutting plate 502. A fixing bolt 504 is threadedly connected to one side of the moving block 501. One end of the fixing bolt 504 is attached to the outer wall of the cutting plate 502, which allows the cutting plate 502 to be moved easily along the strip-shaped hole 503 to cut the material and facilitate further mixing and processing.

[0034] In use, the drive motor can be easily started, causing the drive gear 601 to rotate, which in turn rotates the rotating gear 6, causing the sleeve 4 to rotate, which in turn drives the fixed roller 3 to rotate. At this time, the material to be processed can be easily placed between the adjusting roller 301 and the fixed roller 3 for mixing and processing. The cutting plate 502 can be easily moved along the strip hole 503 to cut the material, facilitating further mixing and processing. At the same time, the transmission rod 7 can be easily rotated according to processing requirements, causing the transmission rod 7 to rotate, which in turn drives the two active helical gears 701 to rotate, which in turn drives the driven helical gears 702 to rotate, which in turn causes the two lead screws 203 to rotate, thereby driving the slider 202 to move synchronously inside the rectangular hole 201. This facilitates the movement of the sleeves 4 at both ends of the adjusting roller 301, thus achieving synchronous driving and movement of both ends of the adjusting roller 301 and avoiding skewing. Moreover, adjustment can be achieved simply by rotating the transmission rod 7, making operation more convenient.

[0035] In use, one end of the spiral cooling pipe 303 can be easily connected to an external cooling water pump via a conduit, and the bottom of the bent pipe 401 at one end can be connected to a corresponding cooling fan via a conduit. Thus, when cooling is required, the corresponding cooling water can be easily delivered to the spiral cooling pipe 303 inside the fixed roller 3 and the adjusting roller 301, thereby achieving cooling of the fixed roller 3 and the adjusting roller 301. At the same time, during use, cold air can also be easily delivered to the sleeve pipe 4 via the fan through the bent pipe 401, and then delivered to the interior of the fixed roller 3 and the adjusting roller 301 through the sleeve pipe 4. Since the fixed roller 3 and the adjusting roller 301 are equipped with multiple cooling blades 302, the cooling blades 302 can be easily cooled, thereby improving the cooling efficiency of the fixed roller 3 and the adjusting roller 301.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
