Description

Technical Field

[0001] This utility model relates to the field of transmission technology, and in particular to a transmission structure for a knife grinding machine. Background Technology

[0002] As is well known, the transmission structure of a knife grinding machine is a mechanical system used to transmit power and drive the grinding blades to rotate or reciprocate to achieve knife grinding. It is usually composed of a motor, reducer, transmission belt, transmission shaft and grinding blade clamp, etc. The motor outputs power, the speed and torque are adjusted by the reducer, and then transmitted to the grinding blades by the transmission belt or gears, so that they move along a set trajectory. This structure is widely used in the fields of knife processing and hardware manufacturing. It is necessary to ensure smooth transmission and accurate speed to meet the grinding requirements of different knives.

[0003] In existing electric knife sharpening machines, the transmission mechanism has movable grooves at both ends of the cylindrical grinding wheel bearings, with springs installed in the grooves. However, only one end of the cylindrical grinding wheel is connected to the drive belt. When the drive belt is tensioned, only one end of the cylindrical grinding wheel is directly subjected to the tension of the drive belt. This can easily lead to different spring extension and contraction at the two ends of the cylindrical grinding wheel, causing the two ends of the cylindrical grinding wheel to shift. As a result, the axes of the two cylindrical grinding wheels are not parallel, which will affect the quality of sharpening.

[0004] An existing patent (publication number: CN211388003U) discloses a transmission mechanism for a knife sharpening machine. This utility model provides a transmission mechanism for a knife sharpening machine comprising: a frame, a motor, a drive pulley, a fixed grinding wheel shaft, a driven pulley, a drive bevel gear, a fixed grinding wheel, a movable grinding wheel, a movable grinding wheel shaft, a driven bevel gear, a bevel gear shaft mounting plate, a bevel gear shaft, a first transmission bevel gear, a second transmission bevel gear, a gear positioning ring, a first spring, and a second spring. This mechanism enables synchronous, opposite-direction rotation of the fixed and movable grinding wheels. The movable grinding wheel's position can be adaptively adjusted via the first spring. The second transmission bevel gear maintains engagement with the driven bevel gear under the force of the second spring. Driven bevel gears are provided at both ends of the movable grinding wheel shaft, and the forces on the driven bevel gears at both ends can be kept consistent, ensuring that the movable grinding wheel shaft remains parallel to the fixed grinding wheel shaft. This prevents the movable grinding wheel from shifting relative to the fixed grinding wheel, thus guaranteeing the quality of the knife sharpening.

[0005] To address the aforementioned issues, existing patents offer solutions. However, when driving a belt-driven knife sharpener, the lack of a structure for adjusting the belt drive orientation prevents real-time adjustments based on the required support orientation for the knife, thus reducing the flexibility in adjusting the sharpening orientation.

[0006] Therefore, a transmission structure for a knife grinding machine is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a transmission structure for a knife sharpening machine that can solve the problem that existing belt-driven knife sharpening machines lack a structure for adjusting the orientation of the belt drive, thus making it impossible to adjust in real time according to the different orientations required for sharpening, which reduces the flexibility of adjusting the orientation of the sharpening machine.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a transmission structure for a knife grinding machine, comprising an adjustment mechanism and a transmission mechanism, wherein the transmission mechanism is located in front of the adjustment mechanism;

[0009] The adjustment mechanism includes a positioning frame, guide slides, a guide frame, an electric spacing adjustment screw, an electric height adjustment screw, and an adjustment slider. The two guide slides are fixedly connected to the bottom of both sides of the positioning frame. The guide frame is fixedly connected to the side of the guide slides away from the positioning frame. The electric spacing adjustment screw is fixedly connected to the top of the guide frame. The electric height adjustment screw is fixedly connected to the inside of the positioning frame. The adjustment slider is slidably connected to the inside of the positioning frame. The inside of the adjustment slider is threadedly connected to the surface of the electric height adjustment screw.

[0010] Preferably, the transmission mechanism includes an adaptation component and a grinding component. The adaptation component is located at the bottom of the surface of the electric pitch adjusting screw, and the bottom of the adaptation component contacts the top of the guide slide. The grinding component is located on the front side of the adjusting slider and the front side of the adaptation component, respectively.

[0011] Preferably, the adaptation component includes an adaptation frame, an electric adaptation adjustment screw, an adaptation guide plate, and an adaptation slider. The two adaptation guide plates are respectively threaded to the surface of the electric pitch adjustment screw. The adaptation frame is fixedly connected to the bottom of the adaptation guide plate. The electric adaptation adjustment screw is fixedly connected to the inner side of the adaptation guide plate. The adaptation slider is slidably connected to the inner side of the adaptation frame. The inner side of the adaptation slider is threadedly connected to the surface of the electric adaptation adjustment screw.

[0012] Preferably, the polishing assembly includes an adjusting electric rotating plate, a transmission electric wheel, an adapting electric wheel, and a polishing belt. The adjusting electric rotating plate is fixedly connected to the front side of the adjusting slider. The two transmission electric wheels are respectively fixedly connected to the two sides of the front side of the adjusting electric rotating plate. The two adapting electric wheels are respectively fixedly connected to the front side of the two adapting sliders. The polishing belt is respectively sleeved on the surface of the transmission electric wheel and the surface of the adapting electric wheel.

[0013] Preferably, limiting plates are fixedly connected to both sides of the top of the positioning frame, and the two sides of the limiting plates are rotatably connected to the side of the electric spacing adjustment screw near the positioning frame.

[0014] Preferably, guide plates are fixedly connected to both sides of the inner side of the positioning frame, and the surface of the guide plates is slidably connected to both sides of the adjusting slider.

[0015] Preferably, an auxiliary guide sleeve is fixedly connected to the bottom of the adaptation frame, and the bottom of the auxiliary guide sleeve is slidably connected to the top of the guide rod.

[0016] Preferably, anti-deviation plates are fixedly connected to the front side of both the transmission electric wheel and the adaptation electric wheel, and the inner side of the anti-deviation plate is in contact with the surface of the grinding belt.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting an adjustment mechanism, allows the positioning frame to cooperate with the guide slide, guide frame, electric pitch adjustment screw, electric height adjustment screw, and adjustment slider. The positioning frame supports and limits the guide slide and electric height adjustment screw, allowing the guide slide to support the guide frame. The guide frame also supports and limits the electric pitch adjustment screw, enabling the guide slide and electric pitch adjustment screw to guide and limit the movement of the transmission mechanism using the positioning frame and electric pitch adjustment screw as support points. This facilitates adaptive orientation adjustment of the transmission mechanism, allowing it to adapt to the required grinding orientation. The electric pitch adjustment screw drives the transmission mechanism to adjust the pitch, and the electric height adjustment screw drives the adjustment slider to adjust the height, thereby changing the height orientation of the transmission mechanism and allowing it to adapt to different tool grinding orientation requirements.

[0019] 2. This application, by setting a transmission mechanism, allows the adapting component to cooperate with the grinding component. The adapting guide plate, driven by the adjustment mechanism, can adjust the orientation of the adapting component and the adapting electric wheels, changing the distance between them to accommodate the deformation required by the grinding belt. The electric adapting adjustment screw can drive the adapting slider to adjust the height of the adapting electric wheels, further accommodating the deformation required by the grinding belt. The adjusting electric rotating plate can adjust the angle of the transmission electric wheels, further adjusting their orientation when limiting the grinding belt. By moving the grinding belt across the surfaces of the transmission and adapting electric wheels at different orientations, the distance between the grinding belt and each transmission and adapting electric wheel can be changed. As the distance decreases, the tension of the grinding belt increases, thereby improving the stability during tool grinding. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A transmission structure for a knife grinding machine includes an adjustment mechanism 1 and a transmission mechanism 2, wherein the transmission mechanism 2 is located in front of the adjustment mechanism 1;

[0030] The adjustment mechanism 1 includes a positioning frame 11, guide slide rods 12, guide frame 13, electric spacing adjustment screw 14, electric height adjustment screw 15, and adjustment slider 16. The two guide slide rods 12 are fixedly connected to the bottom of both sides of the positioning frame 11, and the guide frame 13 is fixedly connected to the side of the guide slide rods 12 away from the positioning frame 11. The electric spacing adjustment screw 14 is fixedly connected to the top of the guide frame 13, and the electric height adjustment screw 15 is fixedly connected to the inner side of the positioning frame 11. The adjustment slider 16 is slidably connected to the inner side of the positioning frame 11, and the inner side of the adjustment slider 16 is threadedly connected to the surface of the electric height adjustment screw 15.

[0031] In this embodiment: By setting the adjustment mechanism 1, the positioning frame 11 can cooperate with the guide slide rod 12, the guide frame 13, the electric pitch adjustment screw 14, the electric height adjustment screw 15, and the adjustment slider 16. The positioning frame 11 supports and limits the guide slide rod 12 and the electric height adjustment screw 15, allowing the guide slide rod 12 to support the guide frame 13. The guide frame 13 supports and limits the electric pitch adjustment screw 14, allowing the guide slide rod 12 and the electric pitch adjustment screw 14 to guide and limit the movement of the transmission mechanism 2 with the positioning frame 11 and the electric pitch adjustment screw 14 as support points. This facilitates the adaptive orientation adjustment of the transmission mechanism 2, enabling it to adapt to the required grinding orientation. The electric pitch adjustment screw 14 can drive the transmission mechanism 2 to adjust the pitch, and the electric height adjustment screw 15 can drive the adjustment slider 16 to adjust the height, thereby changing the height orientation of the transmission mechanism 2 and allowing it to adapt to different tool grinding orientation requirements.

[0032] Specifically, such as Figure 4 As shown, the transmission mechanism 2 includes an adaptation component 21 and a grinding component 22. The adaptation component 21 is located at the bottom of the surface of the electric pitch adjusting screw 14, and the bottom of the adaptation component 21 contacts the top of the guide slide 12. The grinding component 22 is located on the front side of the adjusting slider 16 and the front side of the adaptation component 21, respectively.

[0033] Specifically, such as Figure 5 As shown, the adaptation component 21 includes an adaptation frame 211, an electric adaptation adjustment screw 212, an adaptation guide plate 213, and an adaptation slider 214. The two adaptation guide plates 213 are respectively threaded to the surface of the electric pitch adjustment screw 14. The adaptation frame 211 is fixedly connected to the bottom of the adaptation guide plate 213. The electric adaptation adjustment screw 212 is fixedly connected to the inner side of the adaptation guide plate 213. The adaptation slider 214 is slidably connected to the inner side of the adaptation frame 211. The inner side of the adaptation slider 214 is threadedly connected to the surface of the electric adaptation adjustment screw 212.

[0034] Specifically, such as Figure 6As shown, the grinding assembly 22 includes an adjusting electric rotating plate 221, a transmission electric wheel 222, an adapting electric wheel 223, and a grinding belt 224. The adjusting electric rotating plate 221 is fixedly connected to the front side of the adjusting slider 16. The two transmission electric wheels 222 are respectively fixedly connected to the two sides of the front side of the adjusting electric rotating plate 221. The two adapting electric wheels 223 are respectively fixedly connected to the front side of the two adapting sliders 214. The grinding belt 224 is respectively sleeved on the surface of the transmission electric wheel 222 and the surface of the adapting electric wheel 223.

[0035] In this embodiment: by setting the transmission mechanism 2, the adapting component 21 can cooperate with the grinding component 22. With the adjustment mechanism 1 driving the adjusting guide plate 213, the adapting frame 211 can adjust the position of the adapting component 21 as a whole and the adapting electric wheel 223, changing the distance between the adapting electric wheels 223 to adapt to the deformation required by the grinding belt 224. The electric adapting adjustment screw 212 can drive the adapting slider 214 to adjust the height of the adapting electric wheel 223, thereby further adapting to the deformation required by the grinding belt 224. Adjusting the electric rotating plate 221 can drive the transmission electric wheel 222 to adjust its angle, thereby further adjusting the position of the transmission electric wheel 222 when limiting the grinding belt 224. By moving the transmission electric wheel 222 and the adapting electric wheel 223 on the surface of the grinding belt 224 in different positions, the distance between the grinding belt 224 and the various transmission electric wheels 222 and adapting electric wheels 223 can be changed. As the distance decreases, the tension of the grinding belt 224 will increase, thereby improving the stability of the tool grinding.

[0036] Specifically, such as Figure 3 As shown, limiting plates 17 are fixedly connected to both sides of the top of the positioning frame 11, and the two sides of the limiting plates 17 are rotatably connected to the side of the electric spacing adjustment screw 14 near the positioning frame 11.

[0037] Specifically, such as Figure 3 As shown, guide plates 18 are fixedly connected to both sides of the inner side of the positioning frame 11, and the surface of the guide plates 18 is slidably connected to both sides of the adjusting slider 16.

[0038] In this embodiment: by setting a limiting plate 17 and a guide plate 18, the limiting plate 17 can cooperate with the electric pitch adjusting screw 14. The limiting plate 17 provides auxiliary limiting for the side of the electric pitch adjusting screw 14 near the positioning frame 11, which can further increase the stability of the electric pitch adjusting screw 14 when rotating. The guide plate 18 can cooperate with the adjusting slider 16. The guide plate 18 guides the sliding of the adjusting slider 16, which can further increase the stability of the adjusting slider 16 when moving within the positioning frame 11.

[0039] Specifically, such as Figure 5 As shown, an auxiliary guide sleeve 215 is fixedly connected to the bottom of the adaptation frame 211, and the bottom of the auxiliary guide sleeve 215 is slidably connected to the top of the guide rod 12.

[0040] Specifically, such as Figure 6 As shown, anti-deviation plates 225 are fixedly connected to the front side of the transmission electric wheel 222 and the front side of the adaptation electric wheel 223, and the inner side of the anti-deviation plate 225 is in contact with the surface of the sanding belt 224.

[0041] In this embodiment: by setting an auxiliary guide sleeve 215 and an anti-deviation plate 225, the auxiliary guide sleeve 215 can cooperate with the guide rod 12. By sliding the auxiliary guide sleeve 215 on the guide rod 12, the movement of the adaptation frame 211 can be further guided, increasing the stability of the adaptation frame 211 during movement. The anti-deviation plate 225 can cooperate with the transmission electric wheel 222 and the adaptation electric wheel 223. By limiting the surface of the sanding belt 224, the anti-deviation plate 225 can further increase the stability of the sanding belt 224 when it moves on the surface of the transmission electric wheel 222 and the adaptation electric wheel 223.

[0042] Working principle: First, after connecting the adjustment mechanism 1 and transmission mechanism 2 to the remote control terminal and powering it on, the user can then operate the adjustment mechanism 1 and transmission mechanism 2 through the remote control terminal. When the tool needs to be sharpened, the electric height adjustment screw 15 will drive the adjustment slider 16 to move up and down within the positioning frame 11. At the same time, the electric spacing adjustment screw 14 will drive the adaptation guide plate 213 to adjust the orientation of the adaptation frame 211 left and right. Simultaneously, the electric adaptation adjustment screw 212 will drive the adaptation slider 214 to adjust up and down along the adaptation frame 211. At this time, the electric adjustment rotating plate 221 will move with the movement of the adjustment slider 16, and the adaptation electric wheel 223 will... As the adapting slider 214 moves, the abrasive belt 224 adjusts its shape accordingly with the movement of the drive electric wheel 222 and the adapting electric wheel 223. Once the adapting electric wheel 223 and the drive electric wheel 222 have moved to the desired position, the adjusting electric rotating plate 221 will drive the drive electric wheel 222 to rotate, thereby further adjusting the position of the top of the abrasive belt 224 until it has rotated to the desired angle. Then, the drive electric wheel 222 and the adapting electric wheel 223 will be activated, and the abrasive belt 224 will move. At this point, the tool to be abraded can be placed on the abrasive belt 224 for abrasion.

[0043] 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, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
