Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a lifting device for a pelletizer roller grinder. Background Technology

[0002] In the production process of industries such as plastics, rubber, and chemical fibers, pelletizers are key equipment for turning raw materials into granular products. As a core component, the cutting performance of pelletizer cutters directly affects product quality. With the development of the industry, the requirements for the precision and service life of pelletizer cutters are increasing, which makes the grinding of cutters particularly important.

[0003] Traditional grinding machine lifting devices are mostly simple in structure and single in function, only capable of single lifting and lowering movements. They can only grind one hob at a time. During the grinding process, after one hob is finished, it needs to be removed from the grinding machine and a new hob to be ground needs to be installed. This makes it impossible for multiple grinding machines to work together, which limits the processing volume of the grinding machine per unit time and makes it difficult to adapt to the pace of high-efficiency production. Frequent hob loading and unloading operations not only increase the labor intensity of operators, but also easily cause inaccurate hob installation position due to human factors, affecting grinding accuracy. Therefore, we propose a new type of lifting device for pellet mill hob grinding machines. Utility Model Content

[0004] This utility model provides the following technical solution: a lifting device for a pelletizer roller grinder, comprising a worktable, two through-type T-shaped grooves on the upper end of the worktable, lifting plates slidably connected in both T-shaped grooves, limiting members on the side ends of both lifting plates, motor mounting plates fixedly mounted on the upper ends of both lifting plates, mounting plates connected to the two motor mounting plates via sliding members, roller clamps fixedly mounted on the opposite sides of the two mounting plates, pushing members on the opposing sides of the two mounting plates, lifting gear plates fixedly mounted on the opposite sides of the two lifting plates, lifting gears meshing between the two lifting gears, and servo motors fixedly mounted on the side ends of the lifting gears.

[0005] Preferably, the sliding member includes a groove, which is formed at the upper end of the motor mounting plate. Two limiting slide grooves are formed at the side end of the groove. Limiting slide plates are slidably connected in both limiting slide grooves. A movable plate is fixedly installed on the side wall between the two limiting slide plates.

[0006] Preferably, the pushing component includes a telescopic cylinder, the telescopic end of which is fixedly installed on the side end of the second mounting plate, and a first mounting plate is fixedly installed on one end of the telescopic cylinder, which is fixedly installed on the side end of the motor mounting plate.

[0007] Preferably, the limiting component includes two limiting slide grooves, each of which is provided at both ends of the T-shaped groove. Each of the two limiting slide grooves is slidably connected to a limiting slide plate, and the two limiting slide plates are fixedly installed on both sides of the lifting plate.

[0008] Preferably, a motor mounting plate is fixedly installed on the side end of the servo motor, and the motor mounting plate is fixedly installed on the bottom end of the worktable.

[0009] Preferably, a baffle plate is fixedly installed on the upper end of the second mounting plate, and the baffle plate is set at an angle.

[0010] Preferably, the bottom of the workbench is fixedly equipped with four support legs.

[0011] Preferably, both of the lifting gear plates are connected to the lifting plate by bolts, and the lifting gear is connected to the servo motor by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention enables two grinding machines to work simultaneously, one above the other, by driving a gear plate with a motor. This changes the traditional single-machine sequential grinding mode, allowing the grinding of two hobs to be completed in the same amount of time. This significantly shortens the processing cycle, doubles the production capacity, and meets the quantity requirements of pelletizer hobs for large-scale production. When one grinding machine rises to the grinding station, the other grinding machine descends to a position that is convenient for operators to load and unload the hobs. Loading and unloading are seamlessly connected with grinding, and operators do not need to wait for grinding to be completed before proceeding to the next step. This reduces frequent loading and unloading operations, lowers labor intensity, and improves operational convenience. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a lifting device for a pelletizer roller grinder, including a worktable 1. The upper end of the worktable 1 has two through-type T-slots 2. Lifting plates 3 are slidably connected in both T-slots 2. Limiting members are provided on the side ends of both lifting plates 3. Motor mounting plates 7 are fixedly installed on the upper ends of both lifting plates 3. Mounting plates 2 18 are connected to both motor mounting plates 7 through sliding members. Roller clamps 19 are fixedly installed on the opposite side ends of mounting plates 2 18. Pushing members are provided on the opposite side ends of the two mounting plates 2 18. Lifting gear plates 4 are fixedly installed on the opposite side ends of both lifting plates 3. Lifting gear plates 4 are meshed with lifting gears 5. Servo motors 6 are fixedly installed on the side ends of lifting gears 5.

[0022] In an optional embodiment: the slider includes a groove 13, which is formed on the upper end of the motor mounting plate 7. Two limiting slide grooves 14 are formed on the side end of the groove 13. Limiting slide plates 15 are slidably connected in both limiting slide grooves 14. A movable plate 16 is fixedly installed on the side wall between the two limiting slide plates 15.

[0023] It should be noted that this ensures that the hob clamp 19 always maintains a linear motion under the push of the telescopic cylinder 11, avoiding deviation in the hob grinding position due to lateral offset.

[0024] In an optional embodiment: the pusher includes a telescopic cylinder 11, the telescopic end of which is fixedly mounted on the side of the mounting plate 18, and one end of the telescopic cylinder 11 is fixedly mounted on the mounting plate 10, which is fixedly mounted on the side of the motor mounting plate 7.

[0025] It should be noted that the clamped hob is pushed toward the grinding position.

[0026] In an optional embodiment: the limiting member includes two limiting slide grooves 8, both of which are provided at both ends of the T-shaped groove 2, and both limiting slide plates 9 are slidably connected in the two limiting slide grooves 8, and the two limiting slide plates 9 are fixedly installed on both sides of the lifting plate 3.

[0027] It should be noted that this design prevents the lifting gear plate 4 from shifting laterally during sliding, ensuring that it moves precisely in the vertical direction. This avoids poor meshing between the lifting gear 5 and the motor mounting plate 7 due to the offset of the motor mounting plate 7, reduces jamming and noise during equipment operation, extends the service life of the equipment, and makes the grinding machine run more smoothly, ensuring grinding accuracy.

[0028] In an optional embodiment: a motor mounting plate 7 is fixedly mounted on the side of the servo motor 6, and the motor mounting plate 7 is fixedly mounted on the bottom of the worktable 1.

[0029] It should be noted that the servo motor 6 is mounted under the worktable 1 via the motor mounting plate 7.

[0030] In an optional embodiment: a baffle plate 12 is fixedly installed on the upper end of the mounting plate 2 18, and the baffle plate 12 is set at an angle.

[0031] It should be noted that some waste material will be sprayed during grinding. The baffle plate 12 can block the waste material and prevent it from entering the interior of the hob clamp 19 and affecting the jamming of the hob clamp 19.

[0032] In an optional embodiment: a support leg 17 is fixedly installed at the bottom of the workbench 1, and the number of support legs 17 is four.

[0033] It should be noted that the four support legs 17 are arranged in a rectangular shape, providing a stable support structure for the worktable 1. Compared with fewer supports, the four-point support can better distribute the weight of the worktable 1 and the grinding machine, hob, etc. placed on it, and evenly bear the load, ensuring that the entire device will not tilt or shake due to an unstable center of gravity during operation, thus creating a stable foundation for precise grinding operations.

[0034] In an optional embodiment: both lifting gear plates 4 are connected to the lifting plate 3 by bolts, and the lifting gear 5 is connected to the servo motor 6 by bolts.

[0035] It should be noted that with prolonged use of the grinding machine, the tooth surfaces of the lifting gear 5 and the lifting gear plate 4 will gradually wear down and need to be replaced. By removing the bolts, both can be replaced to ensure the normal operation of the grinding machine.

[0036] In practical use, the working principle of this utility model is as follows:

[0037] During operation, the servo motor 6 is connected to an external power source. The output of the servo motor 6 rotates clockwise and counterclockwise, thereby causing the lifting gear 5 to rotate clockwise and counterclockwise. Since the lifting gear 5 is meshed with both lifting gear plates 4, during the rotation of the lifting gear 5, each tooth interacts sequentially with the teeth of the two lifting gear plates 4. Assuming the gear rotates clockwise, the part meshing with the left lifting gear plate 4 will push the upper gear plate upward. At the same time, the lower part of the lifting gear 5 meshes with the right lifting gear plate 4. The lower teeth of the lifting gear 5 gradually contact the teeth of the right lifting gear plate 4 from top to bottom and transmit force, causing the right lifting gear 5 to move downward. The lifting gear 5 rotates in the same direction, generating opposing pushing forces on the two lifting gear plates 4 at different positions, thus achieving the up-and-down movement of the two lifting gear plates 4. Conversely, when the lifting gear 5 rotates counterclockwise, it will push the right lifting gear plate 4 to move along the line, and the left lifting gear plate 4 to move downward, thereby achieving the up-and-down movement of the lifting plate 3 and the motor mounting plate 7. When one motor mounting plate 7 rises to the grinding station, the other motor mounting plate 7 descends to a position that is convenient for the operator to load and unload the hob. Loading and unloading are seamlessly connected with grinding, and the operator does not need to wait for the grinding to be completed before proceeding to the next operation, reducing frequent loading and unloading actions, reducing labor intensity, and improving operational convenience.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
