Description

Technical Field

[0001] The invention relates to the technical field of can cover production and processing, and in particular to an automatic production line for glue injection and drying of can covers. Background Art

[0002] The existing can cover production line is mainly composed of a punching machine, a glue injection machine, a drying oven, and a feeding conveyor belt. The process of making can covers in the entire production line includes: first, the cut sheet material is punched and stretched into a cover blank by cutting and punching, and then the cover blank is stretched and formed multiple times on other punching machines - trimming - flanging - mouth turning - hooking to obtain a formed cover; then, the punched cover is transported to the glue injection machine for glue injection; finally, the glue-injected can cover is transported to the drying oven by the conveyor belt for drying. The existing can cover production line has the following shortcomings:

[0003] 1) When the traditional feeding conveyor belt transports the can lids into the drying oven, the can lids are placed flat or obliquely on the feeding conveyor belt for transportation. Both methods make the distance between two adjacent can lids larger, which easily leads to the problem of insufficient drying time for the can lids when the length of the drying oven is not very long. In order to solve the problem of insufficient drying time, the length of the drying oven needs to be increased, which leads to an increase in production costs and increases the space occupied by the equipment;

[0004] 2) Since the circumferential edge of the can cover is usually curled, the feeding conveyor belt is prone to unstable or uneven feeding when conveying the can cover to the drying oven, which affects the drying effect of the cover. Sometimes the can cover in the drying oven will get stuck, and even the cover in the oven will be scrapped due to over-baking due to the jam, affecting the operation of the production line.

The flipping and feeding station 1 provided in the present invention facilitates the can cover 4 to be transported from the discharge conveyor belt 32 of the glue injection machine 31 to the flipping and feeding station 1 after glue injection, and the can cover 4 is flipped to a vertical state by the flipping mechanism 11 of the flipping and feeding station 1, so that the can cover 4 can be vertically sleeved on the baking guide rod 24 above the feed guide groove 14, so that the can cover 4 on the baking guide rod 24 can be transported in an orderly manner.In the embodiment of the present invention, the flip mechanism 11 includes a flip driving shaft 111 and a flip wheel 112, the flip wheel 112 is sleeved on the flip driving shaft 111, and a magnet is fixed inside the flip wheel 112. By setting the magnet, the can cover 4 transported by the discharge conveyor belt 32 of the glue injection machine 31 can be better sucked and attached to the flip wheel 112 of the flip mechanism 11, so that the front can cover 4 can be pushed forward. The flip transmission mechanism 13 includes a flip driving wheel 132, a flip driven wheel 131, and a flip chain 133.

In specific implementation, the transmission assembly 2333 includes two groups of first pulley bearing seats 23331, a first driving sprocket 23333, a first driven sprocket 23332, and a first synchronous chain 23334. The driving roller 2334 passes through the two groups of first pulley bearing seats 23331 through the two ends of the first transmission driving shaft 2335 respectively. The first driven sprocket 23332 is sleeved on one end of the first transmission driving shaft 2335. The first synchronous chain 23334 is sleeved on the first driving sprocket 23333 and the first driven sprocket 23332.

The first active sprocket 23333 is driven to rotate by the driving motor 2332, and the first driven sprocket 23332 is rotated through the transmission action of the first synchronous chain 23334, thereby driving the first transmission driving shaft 2335 and the driving roller 2334 on the first driven sprocket 23332 to rotate, so as to transmit the cover conveyor belt 231; a protective cover 23336 is fixed to the outside of the first active sprocket 23333, the first driven sprocket 23332 and the first synchronous chain 23334, and the protective cover 23336 covers the outside of the first active sprocket 23333, the first driven sprocket 23332 and the first synchronous chain 23334, which can play a waterproof and dustproof role. The driven transmission mechanism 232 of the present invention comprises a second fixed seat 2321 and two groups of second belt pulley bearing seats 2322 mounted on the second fixed seat 2321, a driven roller 2323, and a second transmission driving shaft 2324.

The driven roller 2323 is sleeved on the outer surface of the second transmission driving shaft 2324. The driven roller 2323 passes through the two ends of the second transmission driving shaft 2324 and passes through the two groups of second belt pulley bearing seats 2322 and is fixed on the two groups of second belt pulley bearing seats 2322. The driven transmission mechanism 233 drives the driven roller 2323 to rotate, so that the can lid 4 passed through by the baking guide rod 24 at the upper end of the lid conveying belt 231 can be conveyed forward along the lid conveying belt 231.

[0040] The entire working principle of the automatic production line of the present invention includes the following processes:

[0041] Step 1) Glue injection: The tank cover 4 is transported to the glue injection machine 31 by the feeding conveyor belt 33. After the tank cover 4 is glued by the glue injection machine 31, it is transported to the turning feeding station 1 by the discharging conveyor belt 32.

[0042] Step 2) Flipping the feeding guide: The can cover 4 placed flat on the discharge conveyor belt 32 is flipped to a vertical state by the flipping wheel 112 of the flipping feeding station 1, and the can cover 4 is vertically sleeved on the baking guide rod 24. The reason for setting the flipping feeding station 1 is that the can cover 4 transported from the discharge conveyor belt 32 of the glue injection machine 31 is placed flat on the discharge conveyor belt 32. To allow the can cover 4 to be sleeved on the baking guide rod 24, it is necessary to flip the flipping wheel 112 of the flipping feeding station 1 to flip the flat can cover 4 to a vertical state. Compared with the traditional feeding method of placing the can cover 4 flat on the conveyor belt, the feeding method of the present invention can shorten the distance between the can covers 4 to the maximum extent, thereby shortening the distance between adjacent can covers 4 in the induction cooker 21, and allowing the can cover 4 to be in the best drying posture to ensure the drying effect of the can cover 4. At the same time, the induction cooker 21 can be made as short as possible under the premise of ensuring the drying effect, thereby reducing production costs and reducing floor space.

[0043] Step 3) Drying: The can cover 4 vertically mounted on the baking guide rod 24 can be stably and orderly transported along the heating tube channel 22 of the induction cooker 21 under the transmission and conveying action of the transmission structure, which is beneficial to uniform heating of the can cover 4 and exposes the surface of the can cover 4 to the drying area, thereby evaporating the glue on the surface of the can cover 4 and achieving a good drying effect.

[0044] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
