Description

Technical Field

[0001] The utility model relates to the technical field of tableware grinding equipment, in particular to a grinding machine. Background Art

[0002] Stainless steel tableware generally includes stainless steel knives and forks and stainless steel spoons. In the production process of stainless steel spoons, in order to ensure the quality and appearance of the product, it is crucial to polish the edge of the spoon. This process is designed to remove burrs, improve the appearance and feel of the product, and thus enhance the consumer's experience.

[0003] In the existing production technology, the polishing process of spoons is usually completed by special grinders. The core component of these grinders is a rotating grinding belt driven by a motor. These grinders can usually only load one grinding belt. In order to improve the burr removal effect on the edge of the spoon during production, one side of the spoon usually needs to be polished twice by the grinding belt to ensure the smoothness of the spoon edge and the quality of the overall appearance. For this reason, the spoon needs to circulate through the grinder on the assembly line or set up two grinders to perform secondary polishing on one side. Although these two methods can improve product quality, they have the following problems:

[0004] 1. Cycle through the grinding machine: increases the production cycle time, resulting in reduced overall production efficiency;

[0005] 2. Set up two grinders: takes up a lot of space and is costly.

[0006] Therefore, it is urgent to develop a novel tableware grinding machine to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0053] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0054] Embodiment 1:

[0055] like Figures 1 to 7 As shown, the utility model discloses a grinding machine, a grinding machine, comprising a base 1, and also comprising:

[0056] Support frame 2;

[0057] The grinding motor 3, the support frame 2 and the grinding motor 3 are respectively installed on both sides of the upper end of the base 1, and a convex pulley 31 is installed at the output end of the grinding motor 3;

[0058] A conical transmission wheel, rotatably connected to the support frame 2;

[0059] First grinding belt 4;

[0060] The second grinding belt 5, the first grinding belt 4 and the second grinding belt 5 are sleeved on the outer sides of the conical transmission wheel and the convex belt wheel 31;

[0061] The radial outer side of the convex pulley 31 is circumferentially provided with a first convex contact surface and a second convex contact surface for tensioning the first grinding belt 4 and the second grinding belt 5 respectively.

[0062] By adopting the above technical solution, two grinding belts are arranged, so that the spoon can contact and grind with the two grinding belts at one time when passing through the grinder, and the traditional secondary grinding process is integrated into one grinder, which has low production cost and short production cycle, and effectively improves the processing efficiency of the spoon. In addition, by arranging the conical transmission wheel, the grinding belt can form a certain inclination angle, so that the spoon can better contact and grind with the grinding belt when passing through the grinding belt;

[0063] During the spoon processing, a clamping mechanism is usually used to clamp the spoon. The spoon can contact the grinding belt through the grinder through the horizontal movement of the clamping mechanism. The clamping mechanism is generally installed on the machine tool and driven to move by a chain. The grinder is placed on one side of the machine tool. The clamping mechanism includes a moving part connected to the machine tool, a moving plate that can extend the moving part is slidably connected to the moving part, and a clamping arm for clamping the spoon is installed on the moving plate. The machine tool is provided with a pressing die that matches the moving plate on the moving path of the clamping mechanism corresponding to the grinder. The contour of the pressing die is adapted to the contour of the edge of the spoon. When the clamping mechanism passes, one end of the moving plate is squeezed and abutted by the pressing die to displace, so that one end of the clamped spoon on the moving plate is extended, so that the moving path of the spoon when passing through the grinder is adapted to the contour of the outer edge of the spoon, so that the grinding belt can better fit the edge of the spoon.

[0064] Finally, the movable plate and the movable part are moved and reset by the reset spring connected thereto;

[0065] The outer edge of the spoon is generally composed of an arc section of the spoon body and an inclined section of the spoon handle. The setting of the conical transmission wheel forms a grinding belt with a certain inclination angle, which enables the edge of the spoon to be evenly stressed when the clamping mechanism drives the spoon to extend and contact the grinding belt, thereby ensuring processing accuracy and avoiding damage to the spoon caused by excessive processing;

[0066] In addition, the grinder of the present application can grind not only stainless steel spoons but also other stainless steel tableware such as stainless steel knives and forks, and has a wide range of applications.

[0067] Embodiment 2:

[0068] This embodiment provides a grinder, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0069] Further, the conical transmission wheel comprises:

[0070] A first conical wheel 6 is rotatably connected to the support frame 2;

[0071] The second conical wheel 7 is fixedly mounted on the end of the first conical wheel 6 away from the support frame 2;

[0072] A retaining ring 8 is fixedly mounted on one end of the second conical wheel 7 relative to the first conical wheel 6;

[0073] The first conical wheel 6 and the second conical wheel 7 are coaxial.

[0074] By adopting the above technical solution, one conical wheel forms an inclined angle for one grinding belt accordingly. When the two grinding belts contact the edge of the spoon, the two grinding belts will not contact and interfere with each other. Each grinding belt can be more accurately aligned with the edge of the spoon, thereby improving the grinding accuracy and quality.

The angle of the grinding area can be adjusted by the rotating member 13, so that the edge of the spoon can be better ground.

[0087] When grinding the spoon, in addition to grinding the vertical surface of the outer edge contour of the spoon, it is also necessary to grind the upper and lower edges of the vertical surface, a total of three surfaces. In the traditional grinding process, at least two grinders are required for each surface to be polished. In this application, a total of three grinders with adjusted swing arm angles are set on one side outside the machine tool, which greatly reduces the processing cost.
