Description

Technical Field

[0001] This utility model relates to the field of bottle cap production technology, specifically to a gripping mechanism for a bottle cap injection molding machine. Background Technology

[0002] Bottle caps are the lids that seal bottles, serving to maintain the airtightness of the contents, prevent tampering, and ensure security. Common types include plastic bottle caps, metal bottle caps, screw caps, and push-button caps. Among these, plastic bottle caps are the most common type, mainly used for various plastic-bottled foods and beverages.

[0003] Bottle caps are made of various materials such as plastic and aluminum, and come in many varieties. During the bottle cap processing, a gripping device is used to remove the bottle caps after they have been formed in the injection molding machine. However, most of the existing bottle cap injection molding machines use a clamping method to grip the bottle caps, which can easily cause the bottle caps to loosen and fall off. Therefore, a gripping mechanism for bottle cap injection molding machines is proposed. When the cylindrical block is inserted into the bottle cap, the first spring pushes the iron column to extend and press against the inside of the bottle cap, thereby fixing the bottle cap to the outside of the cylindrical block and making it less likely to fall off. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a gripping mechanism for a bottle cap injection molding machine. When the cylindrical block is inserted into the bottle cap, the first spring pushes the iron column to extend and press against the inside of the bottle cap, thereby fixing the bottle cap to the outside of the cylindrical block and making it less likely to fall off.

[0005] The technical solution adopted by this utility model to solve its technical problem is a gripping mechanism for a bottle cap injection molding machine, including a frame and a cylindrical block. A cylinder is fixed inside the frame by bolts. The cylindrical block is set on the output shaft at the bottom of the cylinder. Gripping components are provided on both sides of the cylindrical block. The gripping components include insulating sleeves embedded on both sides of the frame.

[0006] An iron sleeve is fixedly fitted inside the insulating sleeve. An electromagnetic coil is fitted on the outer side of the iron sleeve inside the insulating sleeve. A first spring is installed inside the iron sleeve. An iron post is fitted on one end of the iron sleeve.

[0007] By adopting the above technical solution, the cylinder can push the cylindrical block to move up and down, the first spring can push the iron column to extend, and the electromagnetic coil generates magnetism inside the iron sleeve after being energized, which can attract the iron column into the iron sleeve.

[0008] Specifically, a pushing component is provided at the bottom of the cylindrical block. The pushing component includes a limiting groove opened at the bottom of the cylindrical block, and a pushing column is sleeved at the bottom of the limiting groove.

[0009] Specifically, a second spring is fixed to the top of the limiting groove by bolts, and a second limiting plate is fixed to the top of the pusher column located inside the limiting groove by bolts.

[0010] Specifically, the iron column is fixed to a first limiting plate by bolts at one end inside the iron sleeve.

[0011] Specifically, the top of the cylindrical block is provided with a threaded groove, and the cylindrical block is fixed to the bottom output shaft of the cylinder through the threaded groove.

[0012] Specifically, a hanger is welded to the top of the frame.

[0013] The beneficial effects of this utility model are:

[0014] The present invention relates to a gripping mechanism for a bottle cap injection molding machine. An open cylinder pushes a cylindrical block downwards to insert it into the bottle cap. A first spring pushes an iron column outwards, with one end pressing against the inside of the bottle cap, thus fixing the bottle cap onto the cylindrical block and achieving the purpose of gripping it. Power is supplied to an electromagnetic coil to generate magnetism inside the iron sleeve, attracting the iron column into the iron sleeve.

[0015] The present invention describes a gripping mechanism for a bottle cap injection molding machine. When the cylindrical block is inserted into the bottle cap, the pusher is pushed into the limiting groove. When the iron column is adsorbed into the iron sleeve, the second spring pushes the pusher to extend through the second limiting plate, which can push the bottle cap out of the cylindrical block.

[0023] When the cylindrical block is inserted into the bottle cap, the first spring pushes the iron column outward, pressing against the inside of the bottle cap, thus securing the bottle cap to the outside of the cylindrical block and preventing it from easily falling off. Figure 1-4 As shown, the gripping mechanism of the bottle cap injection molding machine of this utility model includes a frame 1 and a cylindrical block 3. A cylinder 2 is fixed inside the frame 1 by bolts. The cylindrical block 3 is set on the output shaft at the bottom of the cylinder 2. Gripping components 4 are provided on both sides of the cylindrical block 3. The gripping components 4 include insulating sleeves 401 embedded on both sides of the frame 1.

[0024] An iron sleeve 402 is fixedly fitted inside the insulating sleeve 401. An electromagnetic coil 403 is fitted on the outer side of the iron sleeve 402 inside the insulating sleeve 401. A first spring 406 is provided inside the iron sleeve 402. An iron post 404 is fitted on one end of the iron sleeve 402.

[0025] When in use, cylinder 2 can push cylindrical block 3 to move up and down, first spring 406 can push iron column 404 to extend, and after electromagnetic coil 403 is energized, magnetism is generated inside iron sleeve 402, which can attract iron column 404 into iron sleeve 402.

[0026] For example, such as Figure 4 As shown, the present invention also includes a pusher assembly 5 at the bottom of the cylindrical block 3. The pusher assembly 5 includes a limiting groove 501 opened at the bottom of the cylindrical block 3, and a pusher post 502 is sleeved at the bottom of the limiting groove 501.

[0027] When in use, the pusher column 502 is fitted onto the bottom of the limiting groove 501 and can move up and down.

[0028] For example, such as Figure 4As shown, the present invention also includes a second spring 504 fixed to the top of the limiting groove 501 by bolts, and a second limiting plate 503 fixed to the top of the pusher column 502 located inside the limiting groove 501 by bolts.

[0029] In use, the second spring 504 can push the pusher column 502 downward, and the second limiting plate 503 can prevent the pusher column 502 from falling out of the limiting groove 501.

[0030] For example, such as Figure 3 As shown, the present invention also includes a first limiting plate 405 fixed to one end of the iron column 404 located inside the iron sleeve 402 by bolts.

[0031] When in use, the first limiting plate 405 is provided to prevent the iron column 404 from falling out of the iron sleeve 402.

[0032] For example, such as Figure 2 As shown, the present invention also includes a threaded groove 6 on the top of the cylindrical block 3, and the cylindrical block 3 is fixed to the bottom output shaft of the cylinder 2 through the threaded groove 6.

[0033] In use, the cylindrical block 3 is fixed to the conveying shaft of the cylinder 2 via the threaded groove 6.

[0034] For example, such as Figure 1 As shown, the present invention also includes a hanger 7 welded to the top of the frame 1.

[0035] When in use, the bracket 7 facilitates the fixing and installation of this device.

[0036] When using this utility model, personnel use bolts to fix the hanger 7 to equipment such as a robotic arm, use a power cord to connect the device to an external power source, and use an air pipe to connect the cylinder 2 to an external air supply device.

[0037] Power is supplied to the electromagnetic coil 403 to generate magnetism inside the iron sleeve 402, which attracts the iron column 404 into the iron sleeve 402. The cylinder 2 is opened to push the cylindrical block 3 down. After the cylindrical block 3 is inserted into the bottle cap, the power supply to the electromagnetic coil 403 is disconnected. The first spring 406 pushes the iron column 404 out, so that one end of it presses against the inside of the bottle cap, thereby fixing the bottle cap on the cylindrical block 3 and achieving the purpose of clamping it.

[0038] When it is necessary to loosen the bottle cap, power is supplied to the electromagnetic coil 403 to generate magnetism inside the iron sleeve 402, which attracts the iron column 404 into the iron sleeve 402.

[0039] When the cylindrical block 3 is inserted into the bottle cap, the pusher 502 is pushed into the limiting groove 501. When the iron column 404 is adsorbed into the iron sleeve 402, the second spring 504 pushes the pusher 502 out through the second limiting plate 503, which can push the bottle cap on the cylindrical block 3 out.
