Abstract
Description
Technical Field
[0001] This utility model relates to the field of paint filling technology, and in particular to a paint filling machine discharge pipe for preventing paint from drying. Background Technology
[0002] As a key piece of equipment in a paint production line, the performance of a paint filling machine directly affects the quality of paint products and production efficiency. During the paint filling process, the discharge pipe is the crucial channel through which paint flows from the storage device to the packaging container; its rational design plays a vital role in the filling effect.
[0003] At the outlet of the filling machine's discharge pipe, residue is easily left after filling stops. Due to factors such as air circulation and temperature, the coating dries and clumps, and when the discharge is stopped for a long time, it can easily block the discharge port and cause waste of coating. Utility Model Content
[0004] To overcome the above-mentioned shortcomings, this utility model provides a discharge pipe for a paint filling machine that prevents paint from drying. It can tightly block and control the temperature at the outlet of the discharge pipe, thus delaying paint drying, and also allows for the cleaning of residual paint inside the discharge pipe after filling is completed.
[0005] The technical solution of this utility model is: a discharge pipe for a paint filling machine to prevent paint from drying, comprising: a discharge pipe, a flange at one end of the discharge pipe, a covering assembly on the discharge pipe, and a blowing assembly on the discharge pipe, wherein the blowing assembly is connected to the covering assembly.
[0006] In one embodiment, the covering assembly includes: an electric push rod fixed to the discharge pipe, an extrusion rod with an extrusion groove fixed to the telescopic end of the electric push rod, a rotating bucket rotatably connected to the opening of the discharge pipe, the rotating bucket being slidably connected to the extrusion groove of the extrusion rod, and a waste discharge pipe disposed on the rotating bucket.
[0007] In one embodiment, the rotating bucket is provided with a rubber ring.
[0008] In one embodiment, the blowing assembly includes: a connecting rod fixed to the extrusion rod, a rack fixed to the connecting rod, an air blowing pipe fixed to the discharge pipe, the air blowing pipe communicating with the discharge pipe, a control valve provided on the discharge pipe, a gear fixed to the valve stem of the control valve, the gear meshing with the rack, and a fixed housing fixed to the air blowing pipe, with both the gear and the rack located inside the fixed housing.
[0009] In one embodiment, the blowing pipe has several branch pipes.
[0010] In one embodiment, a temperature control wire is also included, which is disposed outside the outlet of the discharge pipe and fixed to the outer shell of the outlet of the discharge pipe, with the temperature control wire located inside the shell.
[0011] 1. The rotating bucket is reset by the resetting of the extrusion rod, blocking the outlet of the discharge pipe. When the discharge stops, the outlet of the discharge pipe is blocked. By isolating the air, slowing down solvent evaporation, preventing moisture loss and avoiding the mixing of impurities, the drying of the coating is effectively delayed.
[0012] 2. When the discharge pipe stops discharging, the residual paint inside the pipe is automatically cleaned by blowing air after each filling to prevent paint residue from causing blockage or contamination and to keep the pipeline unobstructed; the discharge pipe is heated by a temperature control wire and maintained at a suitable temperature to prevent the paint from drying out due to temperature in a short period of time.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0019] Example 1: A paint filling machine discharge pipe to prevent paint from drying, such as... Figure 1-4 As shown, it includes: a discharge pipe 1, a flange 2 disposed at one end of the discharge pipe 1, a cover assembly disposed on the discharge pipe 1, and a blow-off assembly disposed on the discharge pipe 1, the blow-off assembly being connected to the cover assembly.
[0020] The covering assembly includes: an electric push rod 3 fixed to the discharge pipe 1, an extrusion rod 4 with an extrusion groove fixed to the telescopic end of the electric push rod 3, a rotating bucket 5 rotatably connected to the opening of the discharge pipe 1, the rotating bucket 5 being slidably connected to the extrusion groove of the extrusion rod 4, and a waste discharge pipe provided on the rotating bucket 5.
[0021] The rotating bucket 5 is equipped with a rubber ring for sealing the opening of the discharge pipe 1.
[0022] The blowing assembly includes: a connecting rod 7 fixed to the extrusion rod 4, a rack 8 fixed to the connecting rod 7, and an air blowing pipe 9 fixed to the discharge pipe 1. The air blowing pipe 9 communicates with the discharge pipe 1. A control valve 10 is provided on the discharge pipe 1. A gear 12 is fixed to the valve stem of the control valve 10. The gear 12 meshes with the rack 8. A fixed housing 11 is fixed to the air blowing pipe 9. Both the gear 12 and the rack 8 are located inside the fixed housing 11.
[0023] The air blowing pipe 9 has several branch pipes for uniformly dispersing the airflow.
[0024] It also includes a temperature control wire 13, which is located on the outside of the outlet of the discharge pipe 1 and fixed to the outer shell 14 on the outside of the outlet of the discharge pipe 1. The temperature control wire 13 is located inside the outer shell 14.
[0025] In use, the operator first installs the discharge pipe 1 via the flange 2. Initially, the control valve 10 is open, the air blowing pipe 9 is connected to the air pump, and the slag discharge pipe 6 is connected to the collection bottle. When discharge is needed, the operator controls the extension end of the electric push rod 3 to extend. The extension end of the electric push rod 3 drives the extrusion rod 4 to move. As the extrusion rod 4 moves, it causes the rotating bucket 5 to rotate at a certain angle under the action of the extrusion groove. The movement of the extrusion rod 4 also drives the rack 8 to move via the connecting rod 7. Under the action of the gear 12, the control valve 10 closes, and the rotating bucket 5 no longer blocks the opening of the discharge pipe 1. The operator controls the discharge pipe 1 to discharge normally. When the discharge pipe 1 stops discharging, the operator controls the extension end of the electric push rod 3 to retract, causing the extrusion rod 4 to reset. As the extrusion rod 4 resets, it causes the rotating bucket 5 to reset under the action of the extrusion groove, and the rotating bucket 5 blocks the discharge pipe 1 again. When discharging stops, the outlet of the discharge pipe 1 is blocked. This effectively delays the drying of the coating by isolating air, slowing solvent evaporation, preventing moisture loss, and avoiding the mixing of impurities. Simultaneously, the extrusion rod 4 resets, and the rack 8 resets via the connecting rod 7. Under the action of the gear 12, the control valve 10 opens, and the air pump blows a high-speed airflow through the air blowing pipe 9. This airflow blows down the coating residue inside the discharge pipe 1, which flows into the rotating hopper 5 and is discharged through the slag discharge pipe 6. Afterwards, the operator turns off the air pump. This automatic cleaning of residual coating inside the discharge pipe 1 after each filling process prevents coating residue from causing blockage or contamination, keeping the pipeline unobstructed. During short-term discharge pauses, the operator controls the temperature control wire 13 without turning on the air pump. The temperature control wire 13 heats the discharge pipe 1 and maintains it at a suitable temperature to prevent the coating from drying out due to temperature issues in a short period.
[0026] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
