Description

Coding feeding and pinching machine for metal pipe fittings

technical field

The invention relates to a code-spraying and feeding pinch machine for metal pipe fittings, which belongs to the technical field of manufacturing metal pipe fittings.

Background technique

With the prosperity and development of the market economy, the cast iron and plastic pipes used in the water supply and heating of the existing construction industry have gradually been replaced by copper water pipes with long life, green environmental protection and easy installation. Many problems have been brought about in the production process and use process, such as: copper water pipes have many specifications and models, and the varieties are complex. There are American standards, European standards, and national standards. Marking products by means of inkjet printers has a positive effect on production and user use.

There are two main methods of inkjet coding at present, one is manual screen printing, the disadvantage is: the printing operation on the surface of the copper tube is troublesome, the copper tube needs to be fixed first, and then printed one by one, the production efficiency is low , the production cost is high; another method is to use advanced inkjet equipment, this method is to fix the inkjet equipment first, put the copper pipe in a groove, and adjust the distance between the inkjet nozzle and the outer surface of the copper pipe , and then manually push them one by one to spray the characters on the outer surface of the copper tube, but the disadvantage is that due to the uneven pushing speed, the size of the sprayed fonts is different and the fonts are deformed. In addition, the above two methods are not applicable to the needs of mass production.

Contents of the invention

The object of the present invention is to provide a pinch feeding machine for coding, feeding and pinching metal pipe fittings with reasonable design, simple structure, convenient operation and reliable operation.

The present invention is a pinch feeding machine for metal pipe fittings, which is characterized in that it includes a base with a motor and a support column, placed on an upper fixed plate with a central shaft on the top of the support column, and placed on the upper fixed plate to mesh with the central shaft and connect with traction The transmission gear of the screw; the fixed block and the adjustment block set in the middle of the supporting column, the fixed block wheel shaft with the transmission wheel and the transmission sprocket placed on the fixed block, the adjustment block wheel shaft with the pressure wheel placed on the adjustment block; the transmission chain The wheel is connected with the motor through a transmission chain, and the bottom of the traction screw is placed in the adjustment block; the top of the traction screw can be fixed on the transmission gear through the traction screw shaft.

The motor can be controlled and driven by a controller placed on the support column.

Compared with the prior art, the present invention has the following outstanding advantages and positive effects:

1. An adjustment block that can adjust the position relative to the fixed block is set on the support column, which can be adjusted at will according to the outer diameter of the copper pipe. A variety of models and specifications can be processed on one machine, which improves the equipment efficiency. Utilization rate: The fonts sprayed out by the pinch machine have a neat appearance, the quality of the outer surface of the product has been improved, the whole machine runs stably and reliably, the floor space is small, the space is saved, and the utilization rate of the plant is improved.

2. Use the controller to adjust the motor's stepless speed, and the printing speed can be adjusted according to different products, making the operation more flexible.

3. The invention is reasonable in design, simple in structure, convenient and practical in operation, and reliable in operation. It is suitable for coding, feeding and pinching of various metal pipe fittings such as copper water pipes. It can effectively improve production efficiency, improve product quality, shorten production cycle, and reduce production. cost.

Detailed ways

The present invention is mainly composed of a base 14 with a motor 13 and a supporting column 7, placed on the upper fixed plate 6 with the central shaft 3 on the top of the supported column 7, and placed on the upper fixed plate 6 to engage with the central axis 3 to connect with the transmission of the traction screw 8. Gears 1 and 4; the fixed block 10 and the adjusting block 9 sleeved in the middle of the support column 7 are placed on the fixed block 10 with a transmission wheel 19 and the fixed block wheel shaft 18 of the transmission sprocket 20, and placed on the adjusting block 9 with pressure The adjusting block wheel shaft 16 of the wheel 17 is formed; the transmission sprocket 20 is connected with the motor 13 through the transmission chain 12, and the bottom of the traction screw 8 is placed in the adjusting block 9; the motor 13 is controlled by the controller 15 placed on the support column 7 Driven, the top of the traction screw 8 is fixed on the transmission gear 1,4 by the traction screw shaft 2,5.

Taking the processing of copper pipes as an example, when working, first adjust the gap between the pressure wheel 17 and the transmission wheel 19 according to the outer diameter of the copper pipe 11. Mesh rotation, the traction screw 8 is rotated simultaneously through the traction screw shafts 2 and 5 respectively, and the adjustment block 9 is driven to rise or fall along the support column 7 according to the rotation direction of the central axis 3, so as to adjust the gap.

Then, turn on the power supply, adjust the knob on the controller 15, so that the feeding speed is suitable for the working conditions, and the operator sends the copper tube 11 into the gap between the pressure roller 17 and the transmission wheel 19 from the feeding table in the direction shown by the arrow in Figure 1 , the machine automatically pinches the copper pipe 11 to the discharge table, installs the inkjet printer nozzle 21 at the outlet of the pinch machine, and sprays the characters to be sprayed on the outer surface of the copper pipe. Repeat the above action to pinch the next pipe again.
