Description

Technical Field

[0001] The utility model belongs to the technical field of glass jar production, and in particular relates to a large-diameter glass jar grinding device. Background Art

[0002] Glass jars are a type of chemical container commonly used in food packaging, gift packaging, and medicinal packaging. They can also be used as a medium for chemical reactions, allowing the reaction process of chemicals to be clearly observed. When used as a medium for chemical reactions, glass jars are used to pour chemicals or are used repeatedly. In this case, the mouth of the jar is prone to wear, which seriously affects the use effect and service life of the glass jar, and even affects the efficiency and quality of the chemical reaction. At present, the mouth of the glass jar has been polished by a grinding device. Although the mouth of the jar can be kept smooth and flat, it cannot effectively clamp the glass jar when clamping, which makes it easy to break during the grinding process, seriously affecting the grinding effect and greatly hindering the subsequent use of the glass jar.

[0003] In the prior art, there are studies on a series of problems caused by the inability of the grinding device to effectively clamp the glass jar, such as patent application CN215847399U, which is an automatic grinding device with a reaction force, etc., which uses a limit rotating disk to touch the container, so that the container can generate a force opposite to the rotation direction of the grinding mechanism under the limit top contact of the limit rotating disk to complete the grinding of the container mouth, which solves the problem that the current grinding device cannot effectively clamp the glass jar, but the existing grinding device is only suitable for small-diameter glass jars or glass parts, but for large-diameter glass jars, a multi-person grinding method is required (multi-person grinding requires at least two people to work together to turn the glass jar upside down on the metal grinding disk, add an appropriate amount of water and sand, and use their hands to push and pull the glass jar on the grinding disk to grind it back and forth). This multi-person grinding method is time-consuming and labor-intensive, extremely slow and inefficient, and is very easy to damage the glass jar due to unstable center of gravity. The metal grinding disk is very easy to wear and has a high cost. It is difficult to accurately control the grinding flatness of the mouth of the large-diameter glass jar, which seriously affects its sealing. Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

The tripod 15 is suspended from the glass tank body 3 by the lifting motor 16, the belt rope 18 and the hook 17.

[0031] See also Figure 1 and Figure 4 A controller 19 for control is fixed on the console 5, and the controller 19 is electrically connected to the lifting motor 16 and a rotating motor 20 for driving the rotating shaft 7 to rotate. The rotating motor 20 is fixed on the side of the bottom of the clamping platform 6 and its output end is connected to the rotating shaft 7 by belt transmission;

[0032] The rotating shaft 7 is rotationally connected to the three-jaw chuck 201 through the controller 19 and the rotating motor 20 . The three-jaw chuck 201 is synchronously rotated with the clamping plate 11 , the frosted chuck 202 and the glass jar body 3 through the rotating shaft 7 .

[0033] The working principle and use process of the utility model: Figure 1-Figure 5 As shown in the figure, after the large-diameter glass jar grinding device is assembled, the operator lifts the glass jar body 3 to the fixed frame 1 through the belt rope 18 fixed with the hook 17, and makes the glass jar body 3 vertical and rotates on the fixed frame 1. The purpose is to solve the problem of unstable center of gravity damage caused by the inverted push-pull grinding of the large-diameter glass jar, so that the operator can easily and quickly complete the grinding of the top jar mouth, and at the same time solve the time-consuming, labor-intensive and slow speed problems caused by multiple people's operation, greatly improve the grinding effect and efficiency, so that the grinding flatness of the jar mouth of the large-diameter glass jar body 3 can be accurately controlled, the loss rate is reduced, the sealing of the large-diameter glass jar body 3 is ensured, and the purpose of semi-automatic operation of the large-diameter glass jar body 3 grinding is achieved.

[0034] When it is necessary to grind a large-diameter glass jar, the operator first rotates the tripod 15 through the rotating buckle 21 to make the tripod 15 in a position where the glass jar body 3 can be lifted, and then operates the controller 19 to start the lifting motor 16. At this time, the belt rope 18 will be driven by the lifting motor 16 to descend to the position of the glass jar body 3, and then the lifting motor 16 will be turned off. Then, the hook 17 at the end of the belt rope 18 will be used to hook the glass jar body 3, and then the lifting motor 16 will be turned on through the controller 19. At this time, the belt rope 18 will be driven by the lifting motor 16 to rise with the glass jar body 3 to the bottom of the tripod 15. , turn off the lifting motor 16, and then drive the tripod 15 to rotate through the rotating buckle 21, so that the glass jar body 3 is pulled to the upper part of the three-claw chuck 201 under the rotation of the tripod 15, and turn on the lifting motor 16 again, so that the bottom of the glass jar body 3 can be against the frosting chuck 202, and then operate the clamping plate 11 on the three-claw chuck 201 to be clamped to the periphery of the frosting chuck 202 through the clamping plate clamping mouth 12 and make it closely against the side wall of the glass jar body 3. At the same time, the mudguard 8 will also assist the clamping plate 11 to contact the side wall of the glass jar body 3, effectively preventing the glass jar body 3 from tilting during grinding. After the glass tank body 3 is clamped and fixed, the operator turns on the rotating motor 20 through the controller 19. At this time, the rotating shaft 7 will drive the three-jaw chuck 201 to rotate under the drive of the rotating motor 20, and the clamping plate 11, the frosting chuck 202 and the glass tank body 3 will rotate synchronously with the rotation of the three-jaw chuck 201. Since the side of the workbench 4 is equipped with a step 401, the polishing personnel will climb onto the operating platform 402 of the workbench 4 via the step 401, apply a proper amount of water and sand on the filling mouth surface of the glass tank body 3, hold the frosting board 13 and press it to the filling mouth of the glass tank body 3, and as the glass tank body 3 is rotated to grind the filling mouth of the glass jar body 3 until the filling mouth of the glass jar body 3 is polished and smooth, then the clamping plate 11 and the fender 8 clamped on the glass jar body 3 are closed and removed, and finally the motor 20 is rotated by the controller 19, and the lifting motor 16 is turned on to lift the glass jar body 3 out of the clamping platform 6 through the belt rope 18 and place it in the specified position. This operation process does not require multiple people to operate, and one person can grind the large-diameter glass jar body 3, which saves time and labor, and the frosted surface of the glass is flat and uniform, with a low loss rate, which greatly improves production efficiency and achieves the purpose of semi-automatic operation of grinding large-diameter glass jar bodies 3.
