Abstract
Description
Technical Field
[0001] This utility model relates to an open-type rubber mixing mill, and in particular to a baffle structure for an open-type rubber mixing mill. Background Technology
[0002] An open-type rubber mixing mill generally includes: a frame, two rollers, a motor to drive the rollers, and a baffle structure. The functions of the baffle structure are: 1. To block the axial sides of the two rollers, restricting the flow of rubber material within the working area of the two rollers and preventing rubber material from leaking out from both ends of the rollers; 2. To guide the rubber material backflow, allowing the rubber material to return to the gap between the two rollers as they rotate.
[0003] Existing baffle structures generally include: a mounting frame fixedly connected to the equipment frame; two mounting parts adjusted axially along the rollers and positioned on the mounting frame; and two plates adjusted vertically in the positions of the two mounting parts. Each plate has two arc-shaped notches that mate with the two rollers, and the plates also serve to block the rubber material. Adjusting the mounting parts to the mounting frame position adjusts the distance between the two plates, primarily for different types and quantities of rubber. Adjusting the plates to the mounting parts position adjusts the distance between the arc-shaped notches and the outer wall of the rollers to a small gap, ensuring that there is no rigid contact between the arc-shaped notches and the outer wall of the rollers while preventing rubber leakage. In existing baffle structures, the adjustment of the mounting parts' positions on the mounting frame and the plates' positions is generally achieved through guide components (such as linear guides or guide posts) and locking components (such as clamps or bolts). After the locking components are released, the mounting parts / plates are manually moved to the corresponding positions, and the locking components are then re-locked.
[0004] The existing baffle structure still has problems: the manual pushing of the mounting part / plate makes it inconvenient to control the specific position, especially for the adjustment of the plate. Utility Model Content
[0005] This application provides a baffle structure for an open rubber mixing mill, which can solve the problems mentioned in the background art.
[0006] This application provides a baffle structure for an open-type rubber mixing mill, comprising: The mounting bracket has two mounting positions on its bottom surface, corresponding to the two horizontal sides respectively. The two first guide members are horizontal and are fixedly connected to the mounting bracket; The rack is horizontal and is fixedly connected to the mounting bracket. Both sets of baffle assemblies include: a first mounting part, an adjusting gear, a plate body, two second guide members, a worm gear module, and a connecting member; The first mounting part is slidably connected to two first guide members, and is also provided with two first locking members matching the first guide members; the adjusting gear is rotatably connected to the first mounting part and also meshes with the rack; Two second guide members are disposed between the plate and the first mounting part, for the plate to slide up and down and be connected to the first mounting part; the plate or the first mounting part is also provided with two second locking members that match the second guide members; The worm gear module is located in the first mounting part; the connecting piece is located between the worm gear and the plate body, and is used to convert the rotation of the worm gear into the linear movement of the plate body.
[0007] In some embodiments, the connector includes: a groove rail disposed on the plate and being horizontal and longitudinal, and a pin disposed on the worm gear and entering the groove rail to form a groove pin pair.
[0008] In some embodiments, the second guide member is a guide post, and the bottom ends of the two second guide members are detachably fixed to the plate; the second locking member is provided with the first mounting part.
[0009] In some embodiments, the second guide member is a threaded section below, the threaded section is threaded with a locking nut, and the bottom end of the threaded section is fixed with an insertion block; the top surface of the plate has two insertion slots, which are inserted into or separated from the insertion block along the horizontal direction.
[0010] In some embodiments, the two locking elements are collets.
[0011] In some embodiments, the first guide is a linear guide, and the first locking element is a guide rail clamp.
[0012] In summary, this application discloses a baffle structure for an open-type rubber mixing mill, comprising: a mounting frame, two first guide members, a rack, and two sets of baffle assemblies. With the first mounting part sliding relative to the mounting frame, manually rotating the adjusting gear allows for relatively smooth horizontal movement of the first mounting part. With the plate body sliding relative to the first mounting part, manually rotating the input shaft drives the output shaft to rotate via a worm gear transmission, which in turn drives the plate body to move up and down via a connecting member. After the plate body moves to the corresponding position, the worm gear self-locks, and the plate body remains in that position even after the input shaft is released. Because one rotation of the screw corresponds to one tooth rotation of the worm gear, the plate body can move slightly, easily achieving a small gap between the two arc-shaped notches of the plate body and the outer walls of the two rollers. The beneficial effect is that adjusting the plate body's position in the horizontal and vertical directions is more convenient. Attached Figure Description

[0017] Please see Figure 1 and Figure 2 A baffle structure for an open rubber mixing mill includes: a mounting frame 1, two first guide members 2, a rack 3, and two sets of baffle assemblies 4.
[0018] The bottom surface of the mounting bracket 1 has two mounting positions 1a, which are fixedly connected to the equipment frame of the open rubber mixing mill, positioning the baffle structure above the two rollers. For ease of explanation of the orientation later, the two mounting positions 1a are defined as corresponding to the horizontal sides respectively.
[0019] More specifically, the mounting bracket 1 may include: two mounting plates 11, multiple mounting strips 12 fixedly connected between the two mounting plates 11, and two mounting positions 1a respectively at the bottom of the two mounting plates 11.
[0020] The two first guide members 2 are horizontal and are fixedly connected to the mounting bracket 1. More specifically, there can be two mounting strips 12, and the two first guide members 2 are fixedly connected to the two mounting strips 12 respectively.
[0021] In some embodiments, the first guide member 2 is selected to be a linear guide.
[0022] The rack 3 is horizontal and is fixedly connected to the mounting bracket 1. More specifically, the rack 3 can be a cylindrical rack 3, and both ends of the rack 3 can be fixedly connected to the two mounting plates 11 by screws.
[0023] The two sets of baffle assemblies 4 have the same structure and are mirror-symmetrical about the longitudinal vertical plane. The baffle assembly 4 includes: a first mounting part 41, an adjusting gear 42, a plate body 43, two second guide members 44, a worm gear module 45, and a connecting member 46.
[0024] The first mounting part 41 is slidably connected to two first guide members 2. If a linear guide is selected for the first guide members 2, then the first mounting part 41 is fixedly connected to the mounting slider 2a on the linear guide.
[0025] The first mounting section 41 is also provided with two first locking members 5 that match the first guide member 2. Since the first guide member 2 is selected as a linear guide, the first locking member 5 is selected as a guide rail clamp. Manually rotating the handle of the guide rail clamp allows the first mounting section 41 to switch between two states: fixed relative to the mounting bracket 1 and sliding relative to the mounting bracket 1.
[0026] The adjusting gear 42 is rotatably connected to the first mounting part 41 and also meshes with the rack 3. When the first mounting part 41 is in a sliding state relative to the mounting bracket 1, manually rotating the adjusting gear 42 can smoothly drive the first mounting part 41 to move horizontally. After the first mounting part 41 moves to the corresponding position, manually rotating the handle of the guide rail clamp switches the first mounting part 41 to a fixed state relative to the mounting bracket 1.
[0027] Two second guide members 44 are disposed between the plate 43 and the first mounting part 41, for the plate 43 to slide up and down and be connected to the first mounting part 41.
[0028] Please see Figure 2 and Figure 3 Specifically, the first guide member 2, the adjusting gear 42, and the plate 43 all need to be connected to the first mounting part 41. More specifically, the first mounting part 41 may include an upper part 411, a middle part 412, and a lower part 413. The upper part 411 and the middle part 412 each have a set of through holes, and the lower part 413 has a set of threaded holes. Screws are threaded through the upper part 411 and the middle part 412 to the lower part 413, thereby fixing the upper part 411, the middle part 412, and the lower part 413 together to form the first mounting part 41. The upper part 411 is used for connecting the adjusting gear 42. The middle part 412 is used for connecting to the first guide member 2. The lower part 413 is used for connecting the plate 43.
[0029] The plate 43 or the first mounting part 41 is also provided with two second locking members 6 that match the second guide member 44. Referring to the function of the first locking member 5, the second locking members 6 switch the plate 43 between two states: fixed relative to the first mounting part 41 and sliding relative to the first mounting part 41.
[0030] Please see Figure 3 and Figure 9The worm gear module 45 is disposed on the first mounting part 41. More specifically, the worm gear module 45 may include: a second mounting part 451, an input shaft 452 with a worm 452a, and an output shaft 453 with a worm gear 453a. The second mounting part 451 is fixedly connected to the first mounting part 41, and the input shaft 452 and the output shaft 453 are both rotatably connected to the second mounting part 451.
[0031] Please see Figure 7 The connecting piece 46 is disposed between the worm gear 453a and the plate 43, and is used to convert the rotation of the worm gear 453a into the linear movement of the plate 43.
[0032] With plate 43 sliding relative to the first mounting part 41, manually rotating the input shaft 452 drives the output shaft 453 to rotate via the worm gear 452a and worm wheel 453a, which in turn drives plate 43 to move up and down via connecting piece 46. After plate 43 moves to the corresponding position, the worm wheel 453a self-locks, and plate 43 remains in the same position even after the input shaft 452 is released. Manually operating the second locking piece 6 switches plate 43 to a fixed state relative to the first mounting part 41. Because one rotation of the screw corresponds to one tooth rotation of the worm wheel 453a, plate 43 can move slightly, easily achieving a small gap between the two arc notches 43b of plate 43 and the outer walls of the two rollers.
[0033] The function of the connecting member 46 is to convert the rotary motion into linear motion. The connecting member 46 can be a connecting rod, with the worm gear 453a as the crank and the plate 43 as the slider, forming a crank-slider mechanism.
[0034] Please see Figure 3 , Figure 7 and Figure 8 The connector 46 may also include: a groove 461 disposed on the plate 43 and being horizontal and longitudinal, and a pin 462 disposed on the worm gear 453a and entering the groove 461 to form a groove pin pair.
[0035] More specifically, a turntable 453b can be fixedly mounted on the end of the output shaft 453 away from the worm gear 453a; the fixed connection position of the second mounting part 451 to the first mounting part 41 can be: the side of the first mounting part 41 away from the plate 43; the first mounting part 41 can also have a hole 41a for the turntable 453b to enter; the pin 462 can be a needle roller bearing, the turntable 453b has a protruding post for the inner ring of the needle roller bearing to be inserted, and the outer ring diameter of the needle roller bearing is equal to the width of the groove 461 in the vertical direction; after the second mounting part 451 is fixedly connected to the first mounting part 41, the turntable 453b is in the hole 41a, and the pin 462 is inserted into the groove 461 of the plate 43.
[0036] The pin 462 is offset from the axis of the output shaft 453. During the rotation of the worm gear 453a, the movement of the pin 462 can be decomposed into: vertical movement and horizontal longitudinal movement. The horizontal longitudinal movement is offset by the movement of the pin 462 in the groove 461, while the vertical movement is retained, thereby driving the plate 43 to move up and down.
[0037] Compared to the crank-slider mechanism, the slotted pin pair has a simpler structure and is easier to assemble.
[0038] Please see Figure 3 and Figure 4 In some embodiments, based on the use of a slotted pin pair for the connector 46, the second guide member 44 is selected to be a guide post, and the bottom ends of the two second guide members 44 are detachably fixed to the plate body 43. Correspondingly, the second locking member 6 is provided with a first mounting part 41.
[0039] The pin 462 enters the groove 461 horizontally. The plate 43 connects to or disconnects from the two second guide members 44 by moving horizontally. At the same time, the groove 461 and the pin 462 can also be connected or disconnected. After the distance between the two rollers is adjusted, the plate 43 can be replaced very easily.
[0040] Please see Figure 4 , Figure 5 and Figure 6 Furthermore, the connection method between the bottom of the plate 43 and the second guide member 44 is as follows: the lower part of the second guide member 44 is a threaded section, which is threadedly connected to a locking nut 44b, and the bottom end of the threaded section is fixed with a plug-in block 44a. The top surface of the plate 43 has two plug-in grooves 43a, which are inserted into or separated from the plug-in block 44a along the horizontal direction.
[0041] More specifically, the plug-in block 44a and the plug-in groove 43a can be trapezoidal. Under the action of gravity, the plug-in groove 43a presses down against the plug-in block 44a, and then the locking nut 44b is tightened to press down against the plate 43, thus fixing the plate 43 to the two plug-in blocks 44a.
[0042] Please see Figure 4 , Figure 5 and Figure 6 Furthermore, the second locking element 6 is selected to be a collet with a matching guide post.
[0043] More specifically, the second locking member 6 may include: a first cylinder 61 fixedly connected to the first mounting part 41, a second cylinder 62 having a gap 62a, and a nut 63 threadedly connected to the first cylinder 61.
[0044] The lower part of the first cylinder 61 is snapped and fixed to the first mounting part 41. The inner diameter of the lower part of the first cylinder 61 is smaller and matches the outer diameter of the guide post. The inner diameter of the upper part of the first cylinder 61 is larger and matches the outer diameter of the second cylinder 62. The outer wall of the upper part of the first cylinder 61 has threads for threaded connection of the nut 63.
[0045] The second cylinder 62 is inserted into the upper part of the first cylinder 61. The inner diameter of the second cylinder 62 is also matched with the outer diameter of the guide post. The outer edge of the top of the second cylinder 62 is also chamfered.
[0046] The through hole of nut 63 is stepped, with a smaller inner diameter at the top and a chamfered angle. It fits the top of the second cylinder 62, which has a larger inner diameter and an internal thread that fits the upper part of the first cylinder 61. When nut 63 is tightened, the outer wall of the second cylinder 62 is subjected to radial pressure, the gap 62a closes, and the inner wall grips the second guide 44, thus achieving locking.
