Description

Technical Field

[0001] This utility model belongs to the technical field of toothed roller crushers, specifically relating to a retraction mechanism for a toothed roller crusher. Background Technology

[0002] A toothed roll crusher is a mechanical device that uses two opposing rotating toothed rolls to crush materials. It is mainly used for coarse or medium crushing of brittle materials with medium hardness or less, such as coal, ore, and limestone. Its working principle is to crush materials into smaller particles through the shearing, squeezing, and splitting action of the roll teeth. It features simple structure, large processing capacity, and low over-crushing rate. Depending on the arrangement and structure of the roll teeth, it can be divided into double-toothed roll and single-toothed roll types, and is widely used in mining, metallurgy, and building materials industries.

[0003] A known authorized patent with application number 202320113247.9 discloses a retraction mechanism for a toothed roller crusher, comprising a toothed roller fixing seat, a fixing seat retraction component, and a crusher housing. The toothed roller fixing seat is used to install both ends of the toothed roller. To facilitate the retraction of the toothed roller, the toothed roller fixing seat is slidably installed on the crusher housing via a slide rail. The fixing seat retraction component is connected to the toothed roller fixing seat, and the toothed roller retraction is achieved through the fixing seat retraction component. A toothed roller retraction element is set inside the toothed roller fixing seat, and the crusher's toothed roller is installed inside the toothed roller fixing seat through the toothed roller retraction element, and the toothed roller retraction is achieved through the toothed roller retraction element. When the first-stage retraction stroke is insufficient, the toothed roller retraction element moves to further increase the retraction stroke of the toothed roller, ensuring that the crushing roller is not damaged when encountering large foreign objects, and further ensuring the service life of the crusher.

[0004] However, during the implementation of the relevant technology, the following problems were found with the above technical solution: when in use, after the device performs a crash action, there is no controllable reset device, which makes it impossible to reset in time, resulting in reduced production efficiency.

[0005] Therefore, a retraction mechanism for a toothed roll crusher is proposed to solve the above problems. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Implementation

[0027] Please see Figure 1-4, a retraction mechanism for a toothed roll crusher, comprising: a frame 1, a crushing roll 2, a drive assembly 3, a fixing assembly 6, and a retraction assembly 14. The crushing roll 2 is rotatably disposed inside the frame 1, and the drive assembly 3 is disposed on the outer wall of the frame 1.

[0028] The fixing component 6 is fixedly connected to the outer wall of the equipment frame 1. The outer wall of the fixing component 6 is slidably connected to the fixing frame 8. A piezoelectric device 11 is provided on one side of the equipment frame 1. Fixing blocks 9 are slidably connected to both ends of the fixing frame 8. A rubber pad 10 is provided on the outer wall of the piezoelectric device 11. A positioning frame 15 is provided on the outer surface of the equipment frame 1.

[0029] A second linear motor 13 is provided on the outer wall of the equipment frame 1;

[0030] The positioning frame 15 contains a crash component 14.

[0031] The technical solution provided in this embodiment is as follows: In use, the drive motor 31 is first started. The power of the drive motor 31 is transmitted to the driven disc 34 through the belt 33, thereby driving the crushing roller 2. When the crushing roller 2 jams, the slight displacement of the jammed roller is transmitted to the jamming block 143. The jamming block 143 transmits the displacement to the fixed frame 8 that is jammed with it. The moving chamber fixed block 9 of the fixed frame 8 moves to one side. At the same time, the rubber pad 10 provides sufficient support force. When the force of the jammed roller is greater than the support force of the rubber pad 10, the fixed block 9 contacts and squeezes the piezoelectric device 11, causing it to generate current. After the current is generated, the first linear motor 63 starts first, quickly pulling out the insertion rod 64. At the same time, the second linear motor drive 13 starts. When the fixed frame 8 is lifted upwards, the engagement between the fixed frame 8 and the locking block 143 is released. Under the action of the tension spring 142, it quickly retracts, completing the flashback action. At the same time, the lifting rod 4 rises to prevent the belt 33 from loosening and falling off due to the retraction of the crushing roller 2, keeping the belt 33 taut at all times. After the flashback, the hydraulic rod 7 is activated, pushing the limit rod 141. At the same time, the second linear motor 13 is activated, pulling up the fixed frame 8. The limit rod 141 pushes the locking block 143 backwards, and the crushing roller 2 resets. After moving to the correct position, the second linear motor 13 pushes the fixed frame 8 downwards, and the first linear motor 63 inserts the insertion rod 64 into the interior of the moving rod 62 to reposition the fixed frame 8.

[0032] Furthermore, the fixing component 6 includes a limiting frame 61, a moving rod 62, a first linear motor 63, and an insert rod 64. The limiting frame 61 is fixedly connected to the outer wall of the equipment frame 1. The moving rod 62 is sleeved inside the limiting frame 61. The insert rod 64 is inserted into the limiting frame 61 and the moving rod 62. The first linear motor 63 is fixedly connected to the outer wall of the equipment frame 1. The output end of the first linear motor 63 is fixedly connected to the insert rod 64. One end of the moving rod 62 is fixedly connected to one end of the second linear motor 13. The end of the moving rod 62 is slidably connected to the fixing frame 8.

[0033] Specifically, by setting the fixing component 6, the fixing frame 8 can be fixed, preventing the fixing frame 8 from shifting during normal operation and affecting the breaking effect of the device.

[0034] Furthermore, the retraction assembly 14 includes a limiting rod 141, a tension spring 142, and a locking block 143. The locking block 143 is slidably connected inside the positioning frame 15, and the shaft of the crushing roller 2 is rotatably connected to the inner wall of the locking block 143. One end of the tension spring 142 is fixedly connected to the outer wall of the positioning frame 15, and the other end of the tension spring 142 is fixedly connected to the outer wall of the locking block 143. The limiting rod 141 is fixedly connected to the outer wall of the locking block 143 and passes through the positioning frame 15.

[0035] Both the lower wall of the fixed frame 8 and the upper wall of the locking block 143 are provided with locking teeth 12, and the fixed frame 8 and the locking block 143 are engaged by the locking teeth 12.

[0036] Specifically, by setting the flashback component 14, when the fixed frame 8 separates from the card block 143, the crushing roller 2 is quickly pulled to one side under the action of the tension spring 142, thereby increasing the distance between the two crushing rollers 2.

[0037] Furthermore, a hydraulic rod 7 is provided on the outer wall of the equipment frame 1, and the output end of the hydraulic rod 7 corresponds to the position of the limiting rod 141.

[0038] Specifically, the hydraulic rod 7 can reset the crushing roller 2 by moving the limit rod 141.

[0039] Furthermore, the drive assembly 3 includes a drive motor 31, a drive disc 32, a belt 33, and a driven disc 34. The drive motor 31 is fixedly connected to the outer wall of the equipment frame 1. The drive disc 32 is fixedly connected to the output end of the drive motor 31. The driven disc 34 is fixedly connected to one end of the crushing roller 2. The belt 33 is sleeved on the outer wall of the driven disc 34 and the drive disc 32. A lifting rod 4 is fixedly connected to the outer wall of the equipment frame 1. A top wheel 5 is provided at the output end of the lifting rod 4, and the top wheel 5 is in contact with the belt 33.

[0040] Specifically, the transmission via belt 33 ensures that after the equipment retracts, the top pulley 5 keeps belt 33 taut, guaranteeing uninterrupted power transmission.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
