Description

Technical Field

[0001] This utility model relates to the field of grinding wheel processing technology, specifically to an easily adjustable feeding device for grinding wheel processing. Background Technology

[0002] A grinding wheel is a porous cutting tool made by pressing and sintering abrasive, binder, and pores in a certain proportion. Its cutting ability comes from the sharp edges of the abrasive particles. Grinding wheels are one of the most important types of grinding tools used in workpiece grinding operations. Most are circular with a through hole in the center. Grinding wheels are generally formed by extruding abrasive and binder materials inside a mold. During the processing, a feeding device is required to feed the abrasive used in grinding wheels into the mold.

[0003] A feeding device is required in the grinding wheel processing. Chinese utility model patent CN218057575U discloses an easily adjustable feeding device for grinding wheel processing, including a feeding box. Support legs are vertically fixed at both ends of the bottom of the feeding box, and a top cover is provided at the bottom of the feeding box. A feed inlet is fixed at the top of the top cover. In use, after the abrasive material is introduced into the feeding box, a first drive motor can be started to rotate the shaft. The rotation of the shaft drives multiple sets of externally fixed sleeves to rotate, which in turn drives externally fixed crushing blades to rotate. This auxiliary agitation and crushing of the abrasive inside the feeding box effectively breaks up any clumps, facilitating feeding and pressing into the grinding wheel. This solves the problem of the difficulty in auxiliary crushing and breaking up of the abrasive inside the feeding device.

[0004] However, this utility model does not have an anti-clogging structure during use. Since the raw material in the grinding wheel is usually in powder form, it is very easy to get clogged during the feeding process, which requires manual unblocking by the staff, affecting the actual feeding efficiency and failing to meet production needs. Therefore, an easily adjustable feeding device for grinding wheel processing is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an easily adjustable feeding device for grinding wheels, which has the advantage of preventing clogging. This solves the problem that existing feeding devices do not have an anti-clogging structure. Since the raw materials in the grinding wheel are usually in powder form, clogging is very likely to occur during the feeding process, requiring manual unclogging by workers, which affects the actual feeding efficiency and cannot meet production needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easily adjustable feeding device for grinding wheel processing, comprising a worktable and a feeding box disposed on the top of the worktable, wherein the bottom of the feeding box is provided with an anti-clogging mechanism that can prevent abrasive clogging;

[0007] The anti-clogging mechanism includes a feeding hopper fixedly connected to the bottom of the feeding box, a support frame extending to the top of the feeding box fixedly connected to the outside of the feeding box, a drive motor fixedly connected to the top of the support frame, a drive shaft extending into the inside of the feeding hopper fixedly connected to the output shaft of the drive motor, a discharge pipe fixedly connected to the bottom of the feeding hopper, a connecting shaft extending into the inside of the discharge pipe fixedly connected to the bottom end of the drive shaft, and a spiral feeder fixedly connected to the outside of the connecting shaft.

[0008] Furthermore, the outer surface of the spiral feeder is in contact with the inner wall of the discharge pipe, and a dispersing frame located inside the feed hopper is fixedly connected to the outside of the drive shaft.

[0009] Furthermore, a screening plate connected to the feeding hopper is fixedly connected to the inner bottom wall of the feeding box, and a cleaning plate is fixedly connected to the outside of the drive shaft, with the lower surface of the cleaning plate abutting against the upper surface of the screening plate.

[0010] Furthermore, a vibration motor is fixedly connected to the lower surface of the feeding box, and a main controller capable of driving the vibration motor is fixedly connected to the front of the workbench.

[0011] Furthermore, a support column is fixedly connected to the upper surface of the workbench, and a support spring is fixedly connected between the support column and the feeding box.

[0012] Furthermore, there are four support columns and four support springs, with the four support columns symmetrically distributed on the left and right sides of the vibration motor.

[0013] Furthermore, the bottom of the workbench is fixedly connected with four cushioning pads, which are evenly distributed on the bottom of the workbench.

[0014] Compared with the prior art, this utility model provides an easily adjustable feeding device for grinding wheels, which has the following advantages:

[0015] 1. This easily adjustable feeding device for grinding wheels can drive a drive shaft to rotate via a drive motor. The drive shaft can then simultaneously drive a connecting shaft and a screw feeder to rotate, thereby agitating the abrasive inside the feeding pipe and preventing abrasive blockage. Furthermore, by setting up a screening plate and a cleaning plate, the abrasive can be screened and large pieces of abrasive on the screening plate can be dispersed, thus ensuring the uniformity of abrasive feeding.

[0016] 2. This easily adjustable feeding device for grinding wheels uses a vibrating motor to drive the feeding box to vibrate, thereby feeding the abrasive inside the feeding box. This vibration further prevents the abrasive from clogging on the screening plate, ensuring smooth feeding. This solves the problem that existing feeding devices lack anti-clogging structures. Since the raw materials in the grinding wheels are usually in powder form, clogging is very likely to occur during the feeding process, requiring manual unclogging by workers, which affects the actual feeding efficiency and cannot meet production needs.

[0021] 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.

[0022] Please see Figures 1 to 3 This embodiment provides an easily adjustable feeding device for grinding wheels, including a worktable 1 and a feeding box 2 located on top of the worktable 1. The bottom of the feeding box 2 is provided with an anti-clogging mechanism to prevent abrasive clogging. The anti-clogging mechanism includes a feeding hopper 3 fixedly connected to the bottom of the feeding box 2. A support frame 4 extending to the top of the feeding box 2 is fixedly connected to the outside of the feeding box 2. A drive motor 5 is fixedly connected to the top of the support frame 4. A drive shaft 6 extending into the inside of the feeding hopper 3 is fixedly connected to the output shaft of the drive motor 5. A discharge pipe 8 is fixedly connected to the bottom of the feeding hopper 3. A connecting shaft 9 extending into the inside of the discharge pipe 8 is fixedly connected to the bottom end of the drive shaft 6. A spiral feeder 10 is fixedly connected to the outside of the connecting shaft 9.

[0023] Specifically, the outer surface of the spiral feeder 10 is in contact with the inner wall of the discharge pipe 8, the drive shaft 6 is fixedly connected to the outside of the dispersing frame 7 located inside the feeding hopper 3, the inner bottom wall of the feeding box 2 is fixedly connected to the screening plate 12 which is connected to the feeding hopper 3, the drive shaft 6 is fixedly connected to the outside of the cleaning plate 11, and the lower surface of the cleaning plate 11 abuts against the upper surface of the screening plate 12.

[0024] It should be noted that the inner bottom wall of the feeding box 2 has a certain inclination angle and is inclined towards the screening plate 12. By setting the drive motor 5, the drive shaft 6 can be driven to rotate. The drive shaft 6 can then drive the connecting shaft 9 and the screw feeder 10 to rotate simultaneously, thereby stirring the abrasive inside the feeding pipe 8 and preventing abrasive blockage.

[0025] Please see Figure 1 In this embodiment, a vibration motor 13 is fixedly connected to the lower surface of the feeding box 2, a main controller capable of driving the vibration motor 13 is fixedly connected to the front of the workbench 1, a support column 14 is fixedly connected to the upper surface of the workbench 1, and a support spring 15 is fixedly connected between the support column 14 and the feeding box 2.

[0026] Specifically, there are four support columns 14 and four support springs 15. The four support columns 14 are symmetrically distributed on the left and right sides of the vibration motor 13. The bottom of the worktable 1 is fixedly connected with four buffer pads, which are evenly distributed on the bottom of the worktable 1.

[0027] It should be noted that by setting the vibration motor 13, the feeding box 2 can be driven to vibrate, thereby vibrating and feeding the abrasive inside the feeding box 2. Through vibration, the abrasive on the screening plate 12 can be further prevented from clogging, and the smoothness of feeding can be further guaranteed.

[0028] It should be noted that by setting up cushioning pads, the impact of the workbench 1 on the ground can be reduced, thereby reducing ground vibration.

[0029] The working principle of the above embodiments is as follows:

[0030] First, the worker pours the abrasive from the grinding wheel into the feeding box 2. Then, the vibration motor 13 is started to vibrate and feed the abrasive. After that, the drive motor 5 is started to drive the drive shaft 6 to rotate. At this time, the abrasive is screened by the screen plate 12. When the abrasive enters the feeding hopper 3, the dispersing frame 7 can disperse the screened abrasive a second time and mix it. Then, under the guidance of the spiral feeder 10, it can be fed through the feeding pipe 8.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
