Technical Field

[0001] This utility model belongs to the field of roller press technology, and in particular relates to a roller press that facilitates the replacement of pressure rollers. Background Technology

[0002] Roller press, also known as extrusion mill, roller mill, or double roller mill, is a new type of energy-saving cement grinding equipment. Due to its high efficiency and energy saving, it presents unique advantages and prospects in the crushing industries such as cement, metallurgy, and ore. It can crush materials by extruding and grinding them through internal extrusion rollers. The roller press consists of two rollers that rotate synchronously in opposite directions. The material is fed from above the two rollers and is continuously carried by the rollers into the space between the two extrusion rollers for crushing and grinding. Finally, it is discharged from below.

[0003] Currently, the existing roller press assembly structure is relatively complex. The internal pressure rollers are mostly fixed and installed by flanges and multiple bolts, which makes the installation and fixing of the pressure rollers quite troublesome. Moreover, after a long period of use, when the pressure rollers need to be disassembled and replaced, multiple bolts need to be loosened one by one, which is cumbersome and affects the efficiency of the installation, fixing and disassembly / replacement of the pressure rollers.

[0004] To address the above issues, we propose a roller press that allows for easy replacement of the pressure rollers. Utility Model Content

[0026] This specific embodiment is a roller press that facilitates the replacement of pressure rollers, such as... Figures 1-10As shown, the roller press for easy replacement of pressure rollers includes a roller press body 1 and a front baffle 2. The roller press body 1 has a notch on the front side, and the front baffle 2 cooperates with the notch. Two roller shafts 3 are arranged opposite each other inside the roller press body 1. A pressure roller body 4 is fixedly sleeved on the outer wall of the roller shafts 3. Two sleeves 5 are rotatably embedded on the roller press body 1. Several first slots 6 are opened on the inner wall of the sleeves 5. Several first blocks 7 are fixed on the rear side of the outer wall of the roller shafts 3. The first blocks 7 cooperate with the first slots 6. An avoidance groove is opened on the inner side of the front baffle 2. The front end of the roller shaft 3 cooperates with the avoidance groove. A limiting member is provided on the front baffle 2. A second slot 8 is opened on the front end of the roller shaft 3. The limiting member cooperates with the second slot 8. A connecting member is provided between the front baffle 2 and the roller press body 1.

[0027] In the above structure, by inserting the rear end of the roller shaft 3 into the sleeve 5, and with the cooperation of the first locking block 7 and the first locking groove 6, the rear end of the roller shaft 3 is easily limited and locked. At the same time, the cooperation of the front baffle 2 with the notch, and the cooperation of the front end of the roller shaft 3 with the clearance groove, facilitates the adjustment of the front baffle 2 to seal the notch, and the clearance groove effectively supports the front end of the roller shaft 3. Combined with the limiting component, the front end of the roller shaft 3 is limited and locked, thus realizing the installation and fixing of the roller shaft 3, and thereby achieving the purpose of installing and fixing the pressure roller body 4, without the need for flanges and a large number of bolts. The design facilitates quick disassembly and replacement later, solving the problem of relatively complex assembly structures in existing roller presses. The internal rollers are mostly fixed with flanges and multiple bolts, making installation and fixing cumbersome. Furthermore, after prolonged use, disassembly and replacement of the rollers requires loosening each bolt individually, which is tedious and affects the efficiency of installation, fixing, disassembly, and replacement. The connecting piece facilitates the fixed connection of the front baffle 2 to the roller press body 1, ensuring the stability of the roller body 4 and simplifying its use.

[0028] The limiting component includes a U-shaped frame 9, a lead screw 10, a movable plate 11, a connecting post 12, and a second locking block 13. The U-shaped frame 9 is fixed to the outer side of the front baffle 2. There are two through holes on the front baffle 2. The lead screw 10 is located between the U-shaped frame 9 and the front baffle 2. The movable plate 11 is threaded onto the lead screw 10. The two connecting posts 12 are rotatably connected to the side of the movable plate 11 near the front baffle 2. The second locking block 13 is fixed to the side of the connecting post 12 away from the movable plate 11. Both the connecting post 12 and the second locking block 13 are movablely engaged with the through holes. The second locking block 13 is engaged with the second locking groove 8.

[0029] The connector includes a first positioning hole 14, a first positioning rod 15, a rectangular groove 16, a fixing rod 17, a rectangular plate 18, a second positioning hole 20, and a second positioning rod 21. A T-shaped groove 22 is provided at the bottom of the inner wall of the notch. A T-shaped block 23 is slidably arranged in the T-shaped groove 22 and fixed to the bottom of the front baffle 2. Several first positioning holes 14 are all opened on one side of the roller press body 1. Several first positioning rods 15 are relatively fixed on one side of the front baffle 2. The first positioning rods 15 correspond one-to-one with the first positioning holes 14 and cooperate with each other.

[0030] A rectangular groove 16 is formed through one side of the U-shaped frame 9. One end of the fixing rod 17 is fixedly connected to one side of the movable plate 11, and the other end of the fixing rod 17 passes through the rectangular groove 16 and is fixedly connected to the rectangular plate 18. The fixing rod 17 and the rectangular groove 16 are movably engaged. Several through holes 19 are provided on the front baffle 2. Several second positioning holes 20 are formed opposite to each other on one side of the inner wall of the notch. Several second positioning rods 21 are fixed opposite to each other on the side of the rectangular plate 18 away from the fixing rod 17. The second positioning rods 21 cooperate with the through holes 19 and the second positioning holes 20.

[0031] Support rods 24 are provided on both sides of the lead screw 10. The support rods 24 are fixed between the front baffle 2 and the U-shaped frame 9. The support rods 24 pass through the movable plate 11. The movable plate 11 and the support rods 24 are slidably engaged, which effectively supports and limits the movement of the movable plate 11, ensuring the stability of the movable plate 11 during movement. A knob is rotatably provided on the U-shaped frame 9. The end of the knob near the front baffle 2 is fixedly connected to the lead screw 10.

[0032] A gear 25 is fixedly fitted on the rear side of the outer wall of the sleeve 5. The two gears 25 mesh with each other. A motor 26 is installed on the rear side of the roller press body 1 through a bracket. The output end of the motor 26 is connected to the rear end of the sleeve 5 on the left side. The motor 26 can easily drive the corresponding sleeve 5 to rotate. Under the meshing action of the two gears 25, the two sleeves 5 are driven to rotate synchronously in opposite directions. Combined with the mutual cooperation of the first locking block 7 and the first locking groove 6, the two roller shafts 3 are driven to rotate synchronously, so as to achieve the purpose of adjusting the synchronous operation of the two pressure roller bodies 4, which is convenient for use.

[0033] Example:

[0034] In the initial state, the front baffle 2 is detached from the main body 1 of the roller press. When installing and fixing the pressure roller, first adjust the pressure roller body 4 to be placed inside the main body 1 of the roller press, and insert the end of the roller shaft 3 with the first locking block 7 into the sleeve 5, and insert the first locking block 7 into the corresponding first locking groove 6 on the inner wall of the sleeve 5.

[0035] Secondly, the end of the T-block 23 near the first positioning rod 15 slides into the T-groove 22 through one end, pushing the front baffle 2 to slide along the direction of the T-groove 22, so that the front end of the roller 3 is placed in the clearance groove. As the front baffle 2 continues to slide, until the end face of the front baffle 2 near the first positioning rod 15 abuts against the roller press body 1, thereby driving the first positioning rod 15 to insert into the corresponding first positioning hole 14 and pass out from the other side of the first positioning hole 14;

[0036] At this time, the round hole on the front baffle 2 is on the same axis as the roller 3, and the through hole 19 is on the same axis as the corresponding second positioning hole 20;

[0037] Then, turn the knob to drive the lead screw 10 to rotate. With the threaded engagement between the movable plate 11 and the lead screw 10, and the sliding engagement between the movable plate 11 and the support rod 24, the movable plate 11 moves steadily towards the front baffle 2. Under the action of the connecting column 12, the second locking block 13 moves synchronously until the connecting column 12 passes through the round hole and abuts against the front end of the roller shaft 3. At this time, the second locking block 13 is fully inserted into the second locking groove 8 at the front end of the roller shaft 3, thereby achieving the purpose of limiting and locking the front end of the roller shaft 3, and thus achieving the purpose of installing and fixing the pressure roller body 4. There is no need to use flanges and a large number of bolts for fixing, which solves the drawback that the existing roller press assembly structure is relatively complex, and the internal pressure rollers are mostly fixed and installed by flanges and multiple bolts, which makes the installation and fixing of the pressure rollers more troublesome.

[0038] With the rotational cooperation between the connecting column 12 and the movable plate 11, it is convenient to rotate the second locking block 13 during the adjustment of the movement of the movable plate 11, so that the second locking block 13 is aligned with the second locking slot 8, making it convenient for the second locking block 13 to be inserted into the second locking slot 8.

[0039] When the adjusting plate 11 moves closer to the front baffle 2, it drives the fixing rod 17 to move synchronously along the rectangular groove 16. Under the action of the rectangular plate 18, the second positioning rod 21 passes through the corresponding through hole 19 and is inserted into the bottom of the corresponding second positioning hole 20. Combined with the first positioning rod 15 being inserted into the first positioning hole 14, the purpose of fixing the front baffle 2 and the roller press body 1 together is achieved, thereby ensuring the stability of the second card block 13 inserted into the second card groove 8.

[0040] When the pressure roller body 4 needs to be disassembled and replaced after a long period of use, simply turn the knob in reverse according to the above steps. With the cooperation of the screw 10, the movable plate 11, and the connecting column 12, the second locking block 13 will be driven to disengage from the corresponding second locking groove 8. Under the joint action of the fixed rod 17 and the rectangular plate 18, the second positioning rod 21 will be driven to disengage from the corresponding second positioning hole 20. The front baffle 2 will be slid away from the first positioning hole 14 until the T-shaped block 23 slides out of the T-shaped groove 22. At this time, the pressure roller body 4 together with the roller shaft 3 will be moved forward, so that the rear end of the roller shaft 3 will be disengaged from the sleeve 5. This achieves the purpose of quickly disassembling the pressure roller body 4 and replacing it with a new pressure roller body 4. This solves the problem that the existing roller press assembly structure is relatively complex. Most of the internal pressure rollers are fixed by flanges and multiple bolts. After a long period of use, when the pressure roller needs to be disassembled and replaced, multiple bolts need to be loosened one by one, which is cumbersome and affects the efficiency of the installation, fixing and disassembly of the pressure roller.

[0041] It should be further noted that the installation structure, connection method or setting method of each component in this utility model are all common mechanical methods. As long as they can achieve their beneficial effects, they can be implemented. At the same time, the motor 26 in this utility model is purchased from the market. Those skilled in the art can install and use it according to the requirements.

[0042] The cooperation between the first locking block 7 and the first locking groove 6, combined with the cooperation between the second locking block 13 and the second locking groove 8, facilitates the rotation of the roller shaft 3, and thus facilitates the rotation of the pressure roller body 4 during use.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
