Description

Technical Field

[0001] This utility model relates to the field of toothed roller crusher technology, and in particular to a toothed roller crusher roller spacing adjustment structure. Background Technology

[0002] Toothed roll crushers are equipment suitable for crushing raw materials in industries such as coal, metallurgy, mining, chemicals, and building materials. The roller spacing of a toothed roll crusher can be adjusted mechanically or hydraulically. Mechanical adjustment methods include wedge adjustment, shim adjustment, and top screw adjustment; hydraulic adjustment methods include hydraulic cylinder push-pull adjustment.

[0003] The hydraulic adjustment mechanism usually includes a buffer energy absorption component. When encountering a large hard object, the buffer component protects the movable roller by compressing and displacing it, and then returns to the initial position. When the distance between the movable roller and the fixed roller is small, but the recovery energy of the buffer component is large, the recovery stroke of the movable roller will be large, causing the movable roller and the fixed roller to squeeze and collide, which wears the crushing teeth on the two roller surfaces.

[0004] To address the aforementioned issues, a roller spacing adjustment structure for a toothed roller crusher is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a roller spacing adjustment structure for a toothed roller crusher, which solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A toothed roll crusher roller spacing adjustment structure includes a base, with several mounting grooves formed on both sides of the base, and a movable shaft seat slidably disposed in the mounting groove. The mounting groove is formed on both side walls of the base, and an adjustment component is provided on one side of the movable shaft seat, and a limit component is provided on the other side of the movable shaft seat.

[0008] The adjustment assembly includes an energy-absorbing spring fixedly connected to the movable shaft seat. The end of the energy-absorbing spring away from the movable shaft seat is fixedly connected to a connecting plate that slides along the mounting groove. An adjustment hydraulic cylinder fixed in the mounting groove is fitted to the outside of the connecting plate.

[0009] The limiting assembly includes a top plate that is in movable contact with the movable shaft seat. A symmetrical second displacement sensor is embedded in the side wall of the top plate that contacts the movable shaft seat. A push rod is fixedly connected to the outer side wall of the top plate. The push rod slides in a limiting manner against the inner wall of the mounting groove. A lead screw shaft is threadedly connected to the inner wall of the push rod. A power unit is provided at one end of the lead screw shaft that extends to the outside of the mounting groove.

[0010] Furthermore, a symmetrical first displacement sensor is provided on the outer wall of the movable shaft seat, and both the first displacement sensor and the second displacement sensor are laser displacement sensors.

[0011] Furthermore, the lead screw shaft is rotatably connected to the inner wall of the mounting groove via a bearing, and the power unit includes a driven bevel gear fixed to one end of the lead screw shaft, with a driving bevel gear meshing directly above the driven bevel gear.

[0012] Furthermore, the top of the active bevel gear is interference-fitted with a drive shaft, and the drive shaft passes through the top of the mounting groove and is welded with an internal hex nut.

[0013] Furthermore, one end of the lead screw shaft does not exceed the inner wall of the mounting groove.

[0014] Furthermore, a fixed shaft seat is also provided in the mounting groove.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] This utility model, through the design of a limiting component, allows manual control of the driving and driven bevel gears via an internal hexagonal nut knob, based on the adjustment distance of the hydraulic adjustment mechanism. This, in turn, drives the push rod to move, which in turn moves the top plate. The distance between the second displacement sensor and the movable roller bearing ensures that the top plate is tightly fitted to the positioned movable roller bearing, thus achieving the purpose of limiting and blocking. This prevents the gap between the movable roller and the fixed roller from being damaged by friction due to excessive recovery stroke of the movable roller caused by the buffer component.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-5 As shown, this embodiment provides a toothed roll crusher roller spacing adjustment structure, including a base 1. Several mounting grooves 103 are formed on both sides of the base 1. Movable bearing seats 10 are slidably disposed within the mounting grooves 103. The mounting grooves 103 are formed on both side walls of the base 1. An adjustment component 2 is provided on one side of the movable bearing seat 10, and a limit component 3 is provided on the other side of the movable bearing seat 10. The adjustment component 2 includes an energy-absorbing spring 203 fixedly connected to the movable bearing seat 10. A connecting plate slidably disposed along the mounting groove 103 is fixedly connected to one end of the energy-absorbing spring 203 away from the movable bearing seat 10. 202, an adjusting hydraulic cylinder 201 fixed in the mounting groove 103 is installed on the outer side of the connecting plate 202; the limiting component 3 includes a top plate 301 that is in movable contact with the movable shaft seat 10, a symmetrical second displacement sensor 301a is embedded in the side wall of the top plate 301 that contacts the movable shaft seat 10, a push rod 302 is fixedly connected to the outer wall of the top plate 301, the push rod 302 slides with the inner wall of the mounting groove 103, a lead screw shaft 303 is threadedly connected to the inner wall of the push rod 302, and a power unit is provided at one end of the lead screw shaft 303 that extends to the outside of the mounting groove 103.

[0026] In the above structure, the drive shaft 306 of the movable roller is connected to the movable bearing 10 through a bearing, and the energy-absorbing spring 203 and the movable bearing 10 move synchronously when adjusting the spacing.

[0027] Symmetrical first displacement sensors 101a are provided on the outer wall of the movable bearing 10. Both the first displacement sensor 101a and the second displacement sensor 301a are laser displacement sensors. The first displacement sensor 101a measures the distance between itself and the mounting groove 103 using a laser beam. After processing the data by a computer, the actual distance between the movable roller and the fixed roller is obtained. The second displacement sensor 301a measures the distance between itself and the outer wall of the movable bearing 10 using a laser beam. After calculation by a computer, the distance between the top plate 301 and the movable bearing 10 is obtained. The data from both sets of displacement sensors are displayed in real time on an external display of the toothed roller machine, which is convenient for users to watch and operate at the same time. Both sets of displacement sensors are set as two symmetrical sets, which can improve the accuracy of the measurement data.

[0028] The lead screw shaft 303 is rotatably connected to the inner wall of the mounting groove 103 via a bearing. The power unit includes a driven bevel gear 304 that is sleeved and fixed to one end of the lead screw shaft 303. A driving bevel gear 305 meshes directly above the driven bevel gear (304). The meshing of the two sets of bevel gears has a self-locking function to prevent the top plate 301 from shifting when limiting the movable shaft seat 10.

[0029] The top of the active bevel gear 305 is interference-fitted with a drive shaft 306. The drive shaft 306 passes through the top of the mounting groove 103 and is welded with an internal hex nut 307, which is convenient for users to operate with a wrench. During operation, two people can operate at the same time or one person at a time.

[0030] One end of the lead screw shaft 303 does not exceed the inner wall of the mounting groove 103. This arrangement allows the push rod 302 to fully enter the inner wall of the mounting groove 103, so that the top plate 301 is located on the outer wall of the mounting groove 103 when it is retracted, thus maintaining the maximum effective stroke of the movable shaft seat 10 when adjusting the spacing.

[0031] A fixed bearing 102 is also provided in the mounting slot 103.

[0032] The working principle of this device is as follows:

[0033] The device is connected to the control system and display of the toothed roll crusher. The two sets of regulating hydraulic cylinders 201 are supplied with oil through a unified oil pipeline and operated synchronously by a unified valve control.

[0034] When adjusting the spacing, the device is in a stopped state. Manually rotate the drive shaft 306 with an Allen wrench. The drive shaft 306 drives the active bevel gear 305 to rotate. The active bevel gear 305 meshes with the driven bevel gear 304 to drive the lead screw shaft 303 to rotate. The lead screw shaft 303 drives the push rod 302 to retract the top plate 301 back to the initial position along the inner wall of the mounting groove 103.

[0035] The telescopic joint of the hydraulic cylinder 201 drives the connecting plate 202, the energy-absorbing spring 203, and the movable shaft seat 10 to slide linearly along the inner groove of the base 1. When pulled, the movable shaft seat 10 moves away from the fixed shaft seat 102 to increase the distance. When pushed, the movable shaft seat 10 moves closer to the fixed shaft seat 102 to decrease the distance. At this time, the first displacement sensor (101a) located on the movable shaft seat 10 measures the distance between the movable shaft seat 10 and the mounting groove 103 through laser beam distance measurement. The distance between the movable shaft seat 10 and the fixed shaft seat 102 at this time is calculated by the external controller. The user can accurately control the synchronous adjustment of the movable shaft seats 10 on both sides through the external display.

[0036] After adjustment, the top plate 301, which is in the initial position, is moved in the opposite direction by manual operation. The distance between the top plate 301 and the movable shaft seat 10 is precisely adjusted according to the distance displayed by the second displacement sensor 301a on the display until the top plate 301 and the outer wall of the movable shaft seat 10 are aligned, thus completing the limit operation.

[0037] The above structure can limit and block the movable roller after the adjustment is completed, so that the gap between the movable roller and the fixed roller will not be damaged by friction due to the excessive recovery stroke of the movable roller caused by the buffer component.

[0038] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0039] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
