Each product is made by bonding hundreds or thousands of gauze pieces, so it gets its name. It uses alumina as the abrasive, with the base material being cloth - based. The gauze is made through an assembly line, and then the gauze layers are laminated and fully resin - pasted. Grooves are opened on the upper and lower parts of the chuck to fix the abrasive discs between the upper and lower chucks. At both ends of the inner side of the abrasive disc, an L - shaped buckle groove and a fastening ring are respectively arranged. The fastening ring is fixedly connected with the buckle groove, and the fastening ring is cured and bonded with the buckle groove through glue to form a thousand - page wheel.

[0003] A handle - type impeller is a kind of abrasive disc. During the processing of the handle - type impeller, a handle - type impeller forming machine is used to process the workpiece in sequence. For example, a handle - type impeller forming machine with the application number CN201510630905.1 is a processing device. However, during the processing of the workpiece, the material is only conveyed and fed once through the feeding mechanism. Due to the resilience of the mold and the material piece, the material piece will rebound to a certain extent, affecting the processing accuracy of the feeding. Therefore, a secondary feeding mechanism for a handle - type impeller forming machine is needed to solve the above problems. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a secondary feeding mechanism for a handle - type impeller forming machine, which well solves the problems in the prior art.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Next, in conjunction with the attached Figures 1 - 3 A further detailed description will be made of the specific implementation manners of the present invention.

[0022] As Figures 1 - 3 shown, the present invention includes a machine body 1, a moving plate 2 that can move back and forth on the upper side of the machine body 1, and a processing station 3. In order to accurately push the material for the blade, the processing station 3 is located at the rear side of the moving plate 2. A feeding channel 4 is provided at the front side of the processing station 3. A cutting platform 5 is fixedly connected to the left side of the rear end of the feeding channel 4. A cutter holder 6 that can move left and right is provided on the right side of the cutting platform 5. The cutter holder 6 and the cutting platform 5 cooperate with each other to form a structure for cutting materials. A first pusher 7 that can move back and forth is provided on the left side of the feeding channel 4. A second pusher 8 is provided on the left side of the first pusher 7;

[0023] During use, the material mold can be placed on the upper side of the processing station 3. The feeding channel 4 is used for conveying the uncut material. After the material is conveyed to the rearmost end of the feeding channel 4, it will be cut under the action of the cutter holder 6. At this time, the material (material piece) behind the cutter holder 6 has been conveyed into the mold. Then, with the rotation of the processing station 3, the workpiece mold is driven to rotate. At this time, the first pusher 7 and the second pusher 8 will move backward in sequence as the workpiece rotates, and push the material piece twice. When processing the handle-type impellers with different diameters, by adjusting the position of the moving plate 2 relative to the machine body 1, the processing radius of the first pusher 7, the second pusher 8, and the cutter holder 6 relative to the workpiece can be adjusted, so that the device can be adapted to workpieces with different diameters;

[0024] It should be noted that after the sheet is pushed into the mold, due to the resilience of the mold and the sheet, the sheet will rebound to a certain extent, affecting the processing accuracy of the pushing. Through the two-stage pushing by the first pushing frame 7 and the second pushing frame 8, the pushing position accuracy of the sheet can be higher.

[0025] In addition, during the processing of the workpiece, the moving directions of the first pushing frame 7 and the second pushing frame 8 both coincide with the rotation axis of the processing station 3, and can push the sheet from the radial direction of the processing station 3 to achieve a good pushing effect.

[0026] Furthermore, as shown by Figures 1 - 3 To facilitate the conveyance of the material, two guide wheels 9 rotatably connected to the moving plate 2 are provided on the front side of the feeding channel 4. A driving wheel 10 and a driven wheel 11 are respectively provided on the left and right sides in the middle of the feeding channel 4. A feeding motor 12 fixedly connected to the moving plate 2 is provided below the driving wheel 10. The feeding motor 12 is a servo motor, which is a prior art and will not be described in detail herein.

[0027] Furthermore, as shown by Figures 1 - 3 To facilitate the replacement of the material, a clamping plate 13 slidably connected to the moving plate 2 is rotatably connected below the driven wheel 11. A first cylinder 14 is provided on the right side of the clamping plate 13. The first cylinder 14 is connected to the moving plate 2 by bolts.

[0028] During use, the material passes between the two guide wheels 9 and is placed between the driving wheel 10 and the driven wheel 11. The driving wheel 10 is driven to rotate by the feeding motor 12, and then the conveyance of the material is completed in cooperation with the driven wheel 11. When the material needs to be replaced, the first cylinder 14 can be started to drive the driven wheel 11 to move to the right by the output end of the first cylinder 14, so that the driven wheel 11 is disengaged from the driving wheel 10, and the material can be replaced.

[0029] Furthermore, as shown by Figures 1 - 3 To achieve a better processing effect, a detachable cutting tool 15 is provided on the rear side of the cutting platform 5. A linear reciprocating mechanism 16 is respectively connected to the front side of the first pushing frame 7, the left side of the second pushing frame 8, and the right side of the cutting tool holder 6.

[0030] It should be noted that the structures of the three linear reciprocating mechanisms 16 are the same, and their sizes, setting directions, and connection directions of each component can be adjusted according to actual needs.

[0031] During use, through the three linear reciprocating mechanisms 16, the material can be cut by the cutting tool holder 6, the cut material can be pushed for the first time by the first pushing frame 7, and the cut material can be pushed for the second time by the second pushing frame 8 respectively.

[0032] Further, as Figures 1 - 3 shown, in order to be able to process workpieces of different sizes, a first hydraulic cylinder 17 fixedly connected to the machine body 1 is provided on the front side of the moving plate 2. The moving plate 2 is fixedly connected to the output end of the first hydraulic cylinder 17. A plurality of guide sliders 18 fixedly connected to the base body are provided on the lower side of the moving plate 2. Each guide slider 18 is slidably connected to the moving plate 2;

[0033] During use, through the first hydraulic cylinder 17, the position of the moving plate 2 relative to the machine body 1 can be adjusted. Since the position of the processing station 3 relative to the machine body 1 does not change, workpieces of different diameters can be processed. Through the guide sliders 18, the forward and backward movement of the moving plate 2 can be made more stable.

[0034] Further, as Figures 1 - 3 shown, in order to achieve a better processing effect, the linear reciprocating mechanism 16 includes a power motor 19 connected to the moving plate 2. Each power motor 19 is connected to the moving plate 2 by bolts, and the position of the power motor 19 can be adjusted as needed. A counterweight wheel 20 is fixedly connected to the output end of the power motor 19. One end of a connecting rod 21 is eccentrically connected to the end of the counterweight wheel 20 away from the power motor 19. One side of the connecting rod 21 away from the counterweight wheel 20 is rotatably connected to a linear slider 22. The linear slider 22 is slidably connected to the moving plate 2;

[0035] During use, after the power motor 19 is started, the power motor 19 drives one end of the connecting rod 21 to move through the counterweight wheel 20. Since the counterweight wheel 20 and one end of the connecting rod 21 are eccentrically arranged, one end of the connecting rod 21 will be driven to rotate around the output shaft of the power motor 19, thereby driving the linear slider 22 to perform linear reciprocating movement through the connecting rod 21. It should be further noted that a counterweight block is fixedly connected to the side of the counterweight wheel 20 away from the connecting rod 21, which can offset the acting force between the counterweight wheel 20 and the connecting rod 21 when the counterweight wheel 20 rotates.

[0036] Further, as Figures 1 - 3 shown, in order to facilitate the adjustment of the feeding angle, the first pusher frame 7, the second pusher frame 8, and the cutter frame 6 are respectively fixedly connected to the corresponding linear sliders 22 by bolts;

[0037] It should be noted that long through slots are provided on both the second pusher frame 8 and the cutter frame 6. Through the long through slots and at least two bolts, the directions and positions of the second pusher frame 8 and the cutter frame 6 relative to the corresponding linear sliders 22 can be fixed. A short through slot is provided on the second pusher frame 8. By cooperating with a bolt through the short through slot, the relative angle between the second pusher frame 8 and the corresponding linear slider 22 can be adjusted, so that the second pusher frame 8 can push the material better.

[0038] It should be further noted that the feeding motor 12 and the power motor 19 are both servo motors, which are prior arts and will not be described in detail here. The first cylinder 14 and the first hydraulic cylinder 17 are a cylinder and a hydraulic cylinder respectively, which are also prior arts and will not be described in detail here. In addition, the device is internally provided with a controller, and the above-mentioned electronic components (such as the feeding motor 12, the power motor 19, the first cylinder 14, the first hydraulic cylinder 17, etc.) are all electrically connected to the controller and controlled by the controller. This application does not make improvements to the circuit part, and the control method of the controller is very mature in the prior art and will not be described in the text.

[0039] When the present utility model is in use, first, the material mold can be placed on the upper side of the processing station 3. The feeding channel 4 is used to convey the uncut material. After the material is conveyed to the rearmost end of the feeding channel 4, it will be cut under the action of the cutter holder 6. At this time, the material (material sheet) behind the cutter holder 6 has been conveyed into the mold. Then, with the rotation of the processing station 3, the workpiece mold is driven to rotate. At this time, the first pusher 7 and the second pusher 8 will move backward in sequence as the workpiece rotates, pushing the material sheet twice. When processing a shank impeller with different diameters, the position of the moving plate 2 relative to the machine body 1 can be adjusted, and thus the processing radius of the first pusher 7, the second pusher 8, and the cutter holder 6 relative to the workpiece can be adjusted, enabling the device to be adapted to workpieces with different diameters.

[0040] The structure of the present utility model is novel, ingeniously conceived, and simple and convenient to operate. Through this design, accurate pushing of the material sheet can be achieved, it can be adapted to workpieces with different diameters, facilitating the conveyance of materials and the replacement of materials, achieving a better processing effect, capable of processing workpieces of different sizes, and facilitating the adjustment of the feeding angle.

[0041] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
