[0056] Advantageously, by arranging the first plug board on the first inclined wall, the first plug board can be inclined, avoiding the first plug board being obtrusive and not affecting the conveyance of the product to be ground.

[0057] According to some embodiments of the present invention, there are two guide wheels, two transmission shafts, two gearboxes and two driven gears, and the driven gears are arranged on one side of the two gearboxes away from each other.

[0058] Advantageously, firstly, by arranging two guide wheels, two transmission shafts, two gearboxes and two driven gears, the clamping conveyance of the feeding device can be realized, overcoming the defect that the contact surface between the guide wheel and the product is small and the friction force is small, and preventing the guide wheel from slipping relative to the product to be ground.

[0059] Secondly, the driven gears are arranged on one side of the two gearboxes away from each other, which can prevent the two driven gears from touching each other and reduce the risk of failure.

[0060] Finally, the driven gears are arranged on one side of the two gearboxes away from each other, which also makes the two gearboxes closer to each other. Furthermore, the positions of the two guide wheels can be closer, facilitating the clamping conveyance of thinner products.

[0061] According to some embodiments of the present invention, the gearbox is provided with a first jack for accommodating the transmission shaft, the first jack allows the transmission shaft to be pulled out or inserted, and a key and a keyway are arranged between the first jack and the transmission shaft.

[0063] According to some embodiments of the present invention, a worm and worm gear transmission structure is arranged in the gearbox, the worm is coaxially connected with the driven gear, and the worm gear is coaxially connected with the transmission shaft.

[0064] Advantageously, by arranging the worm and worm gear transmission mechanism, and coaxially connecting the worm with the driven gear and the worm gear with the transmission shaft, the volume of the gearbox can be reduced, especially the volume in the axial direction of the guide wheel, reducing the height of the feeding device.

[0065] According to some embodiments of the present invention, the axial length of the driving gear is set to be unequal to the axial length of the driven gear.

[0066] Advantageously, by relatively extending the axial length of the gear, the meshing range is increased, facilitating the adjustment of the translation seat. At the same time, transmission failure is avoided.

[0067] According to some embodiments of the present invention, the axial length of the driving gear is greater than the axial length of the driven gear.

[0068] Advantageously, by making the axial length of the driving gear greater than the axial length of the driven gear, the adjustment requirements of the translation seat can be met. At the same time, the axial length of the driven gear is relatively reduced, the occupied space of the transmission component is decreased, and contact between the driven gear and the support plate is avoided. Thus, the translation seat has a larger adjustment range.

[0069] According to some embodiments of the present invention, the drive shaft is arranged on the side of the translation seat away from the grinding disc of the grinding machine.

[0070] Advantageously, by arranging the drive shaft on the side of the translation seat away from the grinding disc of the grinding machine, the drive shaft can be kept away from the grinding disc, and at the same time, the guide wheel is closer to the grinding disc, facilitating the guiding of the product to be ground to the grinding disc.

[0071] Moreover, the drive shaft and the drive motor are kept away from the environment of coolant or cooling water, improving the environment where the drive shaft and the drive motor are located.

[0072] According to some embodiments of the present invention, the drive motor is located in the axial direction of the drive shaft, and a coupling is arranged between the drive motor and the drive shaft.

[0073] Advantageously, first, by arranging the drive motor in the axial direction of the drive shaft, the drive motor is kept away from the moving route of the product to be ground, reducing the risk of the drive motor adhering to the coolant and protecting the drive motor.

[0075] Finally, the connection between the drive motor and the drive shaft is also very convenient, facilitating maintenance and repair.

[0076] According to some embodiments of the present invention, it further includes a third cover, and the drive motor is arranged inside the third cover.

[0077] Advantageously, by arranging the third cover, the splashing coolant can be blocked, preventing the coolant from adhering to the drive motor and effectively protecting the drive motor.

[0078] According to some embodiments of the present invention, the third cover is provided with a first box body, the first box body is provided with a wire inlet, the wire inlet accommodates a wire for connecting the drive motor, and the wire inlet is arranged on a horizontal side of the first box body.

[0079] Advantageously: First, by providing the first box body, it is convenient to arrange the control part of the drive motor and also avoid coolant contamination.

[0081] According to some embodiments of the present invention, the wire inlet is arranged on a side of the first box body away from the drive shaft.

[0082] Advantageously: By arranging the wire inlet on a side of the first box body away from the drive shaft, it can prevent the coolant from directly flushing into the first box body.

[0083] According to some embodiments of the present invention, the first box body is provided with a wire outlet, the wire inlet accommodates a wire for connecting the drive motor, the wire outlet is arranged on a horizontal side of the first box body, the wire outlet is arranged on a side of the first box body close to the drive shaft, the wire outlet is provided with a protective cover, and a first notch for accommodating the wire to pass through is arranged at the bottom of the protective cover.

[0084] Advantageously: First, by providing the wire outlet, the wiring requirements can be met, the cable arrangement can be simplified, and the connection is convenient.

[0085] Secondly, by providing the protective cover, it can prevent the coolant from flying in, protect the relevant components, and avoid short circuits.

[0087] According to some embodiments of the present invention, the first box body and the third cover are separately manufactured.

[0088] Advantageously: By separate manufacturing, the manufacturing difficulty is reduced and the manufacturing cost is reduced.

[0089] According to some embodiments of the present invention, the first box body is located on a side of the third cover away from the translation seat.

[0090] Advantageously: The first box body can be far away from the spindle box of the grinding machine, and further, the space occupation is reduced, making the feeding device closer to the grinding disc of the grinding machine.

[0148] In order to mount the gearbox 180, in this embodiment, the translation base 100 includes a translation plate 190 and a first side plate 200 connecting to the edge of the translation plate 190. The guide wheel 120 is mounted on the top of the translation plate 190, and the gearbox 180 is mounted on the first side plate 200.

[0149] Correspondingly, referring to Figure 5 , the translation plate 190 is provided with a first hole portion for accommodating the transmission shaft 170 drivingly connected to the guide wheel 120.

[0150] In this embodiment, by providing the translation plate 190, thus, a large plane is formed, which can facilitate the installation of the guide wheel 120. At the same time, the area occupied by the sliding fit is enlarged, the swaying of the translation base 100 is reduced, and further, the swing of the guide wheel 120 is reduced, so that the guide wheel 120 contacts the product to be ground at multiple positions, ensuring reliable feeding.

[0151] At the same time, by providing the first side plate 200, the gearbox 180 can be conveniently installed, the installation structure of the gearbox 180 is simplified, the installation strength of the translation plate 190 is prevented from being reduced, and the stability of the feeding device is further improved.

[0152] Referring to Figure 7 , in some preferred embodiments, the frame can have a base plate 210. The translation plate 190 is provided on the top of the base plate 210, the gearbox 180 is provided at the bottom of the base plate 210, a guide rail structure is provided between the base plate 210 and the translation plate 190, and the base plate 210 is provided with a second through hole for accommodating the transmission shaft 170 drivingly connected to the guide wheel 120.

[0157] In this embodiment, by providing the first groove, the first pad 220 can be defined to prevent the first pad 220 from deflecting. At the same time, the cooperation between the first pad 220 and the first groove can define the movement range of the translation plate 190, and further define the stroke range of the translation seat 100.

[0158] Refer to Figure 8 , in some preferred embodiments, the driven gear 160 may be arranged on one side away from the two gearboxes 180.

[0159] In this embodiment, first, by providing two guide wheels 120, two transmission shafts 170, two gearboxes 180, and two driven gears 160, the clamping and conveying of the feeding device can be realized, overcoming the defect that the contact surface between the guide wheel 120 and the product is small and the friction force is small, and preventing the guide wheel 120 from slipping relative to the product to be ground.

[0160] Secondly, the driven gear 160 is arranged on one side away from the two gearboxes 180, which can prevent the two driven gears 160 from touching each other and reduce the risk of failure.

[0161] Finally, the driven gear 160 is arranged on one side away from the two gearboxes 180, which also makes the two gearboxes 180 closer to each other. Furthermore, the positions of the two guide wheels 120 can be closer, facilitating the clamping and conveying of thinner products.

[0162] In some preferred embodiments, the gearbox 180 may be provided with a first jack 260 for accommodating the transmission shaft 170. The transmission shaft 170 can be pulled out or inserted into the first jack 260, and a key and a keyway are provided between the first jack 260 and the transmission shaft 170.

[0163] In this embodiment, by providing the first jack 260, the key and the keyway, the transmission shaft 170 can be easily disassembled and assembled with the gearbox 180, simplifying the installation and the manufacture of the gearbox 180.

[0164] In some preferred embodiments, a worm and worm gear transmission structure may be provided in the gearbox 180. The worm is coaxially connected to the driven gear 160, and the worm gear is coaxially connected to the transmission shaft 170.

[0165] In this embodiment, a worm and worm gear transmission mechanism is provided, and moreover, the worm is coaxially connected to the driven gear 160, and the worm gear is coaxially connected to the transmission shaft 170, which can reduce the volume of the gearbox 180, especially the volume along the axis direction of the guide wheel 120, and reduce the height of the feeding device.

[0166] To provide power to the guide wheel 120, referring to Figure 2 , in this embodiment, a driving mechanism is further provided for driving the guide wheel 120 to rotate, which includes a driving gear 130, a driving shaft 140 for mounting the driving gear 130, and a driving motor 150 for driving the driving shaft 140 to rotate. The axis of the driving shaft 140 is arranged along the moving direction of the translation seat 100.

[0167] In some preferred embodiments, the first side plate 200 can be located between the transmission 180 and the driving shaft 140.

[0168] In this embodiment, by making the first side plate 200 located between the transmission 180 and the driving shaft 140, the transmission 180 is close to the driving shaft 140, avoiding unnecessary increase in the volume of the transmission 180 and reducing the weight and cost of the feeding device.

[0169] In some preferred embodiments, it may further include two support plates located at both ends in the length direction of the substrate 210. Both support plates are provided with mounting plates, and the mounting plates are provided with mounting holes for accommodating the driving shaft 140.

[0170] In this embodiment, by providing the support plates, a cavity can be formed at the bottom of the substrate 210, facilitating the accommodation of the transmission 180 and making the structure more compact.

[0171] By providing the mounting plates, the position of the driving shaft 140 is relatively fixed with respect to the support plates and the substrate 210, facilitating assembly and ensuring good meshing transmission between the driving gear 130 and the driven gear 160.

[0172] In some preferred embodiments, the first cover 230 can be provided with a first inclined wall 250, and the driving shaft 140 is arranged at the bottom of the first inclined wall 250.

[0173] In this embodiment, by providing the first inclined wall 250, the occupied space of the first cover 230 can be reduced, making the structure of the feeding device more compact. Moreover, the bottom of the first inclined wall 250 is used to accommodate the driving shaft 140. Therefore, providing the first inclined wall 250 can also prevent incorrect installation.

[0174] In some preferred embodiments, the first plug board can be arranged on the first inclined wall 250.

[0175] In this embodiment, by arranging the first plug board on the first inclined wall 250, the first plug board can be inclined, avoiding the first plug board being obtrusive and not affecting the conveyance of the product to be ground.

[0176] In summary, in this embodiment, first, by providing the guide wheel 120, the translation seat 100, and the power member 110, the position of the guide wheel 120 can be adjusted to form clamping spaces of different sizes, thereby facilitating the clamping of products of different specifications.

[0177] Secondly, by setting the drive shaft 140 such that the axis of the drive shaft 140 is arranged along the moving direction of the translation base 100, it is possible to reduce the height of the feeding device, facilitating its arrangement on various grinding machines without affecting the cooling arrangement of the grinding wheel of the grinding machine, especially in the case where the feeding device is close to the grinding wheel.

[0178] Finally, by setting the transmission mechanism, the direction of rotation is changed to ensure that power can be transmitted to the guide wheel 120, ensuring that the guide wheel 120 can rotate to convey the product to be ground.

[0179] Moreover, the driven gear 160 and the driving gear 130 are arranged in parallel. Therefore, when the translation base 100 is translated and adjusted, the driving gear 130 and the driven gear 160 can still remain engaged, avoiding transmission failure.

[0180] Furthermore, the entire feeding device does not require a separate motor for each guide wheel 120, reducing the number of components and the manufacturing cost.

[0181] At the same time, the motor for driving the guide wheel 120 can also be arranged at a position far from the grinding wheel, reducing the restrictions in arrangement, improving the environment where the motor is located, and prolonging the service life of the motor.

[0182] In some preferred embodiments, the axial length of the driving gear 130 can be set to be unequal to the axial length of the driven gear 160.

[0183] In this embodiment, by relatively extending the axial length of the gear, the meshing range is increased, facilitating the adjustment of the translation base 100. At the same time, transmission failure is avoided.

[0184] In some preferred embodiments, the axial length of the driving gear 130 can be greater than the axial length of the driven gear 160.

[0185] In this embodiment, by making the axial length of the driving gear 130 greater than the axial length of the driven gear 160, the adjustment requirements of the translation base 100 can be met. At the same time, the axial length of the driven gear 160 is relatively reduced, reducing the occupied space of the transmission component and avoiding the driven gear 160 from touching the support plate. Thus, the translation base 100 has a larger adjustment range.

[0186] In some preferred embodiments, the drive shaft 140 can be arranged on the side of the translation base 100 away from the grinding wheel of the grinding machine.

[0187] In this embodiment, by arranging the drive shaft 140 on the side of the translation base 100 away from the grinding wheel of the grinding machine, the drive shaft 140 can be kept away from the grinding wheel, and at the same time, the guide wheel 120 can be made closer to the grinding wheel, facilitating the guiding of the product to be ground to the grinding wheel.

[0188] Moreover, the drive shaft 140 and the drive motor 150 are kept away from the environment of coolant or cooling water, improving the environment where the drive shaft 140 and the drive motor 150 are located.

[0189] In some preferred embodiments, the drive motor 150 can be located in the axial direction of the drive shaft 140, and a coupling is provided between the drive motor 150 and the drive shaft 140.

[0190] In this embodiment, first, by arranging the drive motor 150 in the axial direction of the drive shaft 140, the drive motor 150 is kept away from the movement route of the product to be ground, reducing the risk of the drive motor 150 adhering to the coolant and protecting the drive motor 150.

[0191] Secondly, the drive motor 150 can be easily disassembled from the drive shaft 140, facilitating the arrangement of the feeding device on the grinding machine and reducing the adjustment weight and difficulty.

[0192] Finally, the connection between the drive motor 150 and the drive shaft 140 is also very convenient, facilitating maintenance.

[0193] Refer to Figure 1 , in some preferred embodiments, a third cover can also be included, and the drive motor 150 is arranged inside the third cover.

[0194] In this embodiment, by providing the third cover, the splashing coolant can be blocked, preventing the coolant from adhering to the drive motor 150 and effectively protecting the drive motor 150.
