[0002] During the production process of electric heating tubes, it is often necessary to press rubber caps onto the electric heating tubes. At present, the pressing of the rubber caps is mostly done by workers through simple manual operation of tooling. However, this method requires a lot of manpower, with high labor costs, low degree of automation and work efficiency, low market competitiveness, and is difficult to meet large-scale production and processing.

[0003] In order to improve processing efficiency and automation, cap pressing machines for pressing rubber caps onto electric heating tubes are now beginning to appear on the market. However, since the lead-out rods on the electric heating tubes are long and have low strength, if the holes on the rubber caps and the lead-out rods cannot be effectively aligned, when the rubber caps are pressed onto the electric heating tubes, the lead-out rods may be easily damaged, and the rubber caps may not be accurately pressed onto the electric heating tubes, often resulting in crooked pressing.

[0040] When the present invention is used, on one hand, a large number of rubber caps to be processed can be placed in the vibration plate 81, and the vibration plate 81 vibrates them so that the rubber caps are neatly arranged and then sent out.

[0041] After the rubber cap reaches the discharge port of the vibration plate 81, the push cylinder 82 can be started, and the push cylinder 82 can drive the push block 83 to move, and the push block 83 can push the rubber cap located at the discharge port of the vibration plate 81 to the bottom of the ejector pin 85, and then the pressing cylinder 84 is started, and the pressing cylinder 84 can drive the ejector pin 85 to move downward, and the ejector pin 85 can press the rubber cap located below it into a rubber cap placement groove 11 of the rubber cap seat 1, and then the stepper motor 86 is started, and the slide rail 87 moves a certain distance, and the rubber cap seat 1 moves with the movement of the slide rail 87, so that another empty rubber cap placement groove 11 on the rubber cap seat 1 is located below the ejector pin 85. Repeat the above actions until all the rubber cap placement grooves 11 on the rubber cap seat 1 are placed with rubber caps, and at this time, multiple rubber cap placement grooves 11 are located below multiple pressing pins 53 in a one-to-one correspondence.

[0042] On the other hand, according to the length of the electric heating tube that needs to be processed, the adjustment motor 61 can be started so that the adjustment motor 61 drives the screw 63 to rotate, and the nut 62 located on the screw 63 can move linearly along the screw 63, so as to change the height of the lifting mechanism 3, and the height of the electric heating tube holder 2 connected to the lifting mechanism 3 can also be changed, and finally the height of the electric heating tube holder 2 can be adapted to the length of the electric heating tube that needs to be processed.

[0043] Afterwards, the electric heating tubes to be processed are placed on the electric heating tube mounting grooves 211 of the electric heating tube base 21 of the electric heating tube holder 2.

[0044] Then the lifting cylinder 31 is started, and the lifting cylinder 31 drives the electric heating tube base 21 to move upward. When the electric heating tube located on the electric heating tube base 21 reaches the clamping mechanism 4, the first clamping cylinder 42 and the second clamping cylinder 44 can be started, so that the first clamp 41 and the second clamp 43 are close to each other and clamp the electric heating tube, that is, the clamping mechanism 4 can be used to clamp the electric heating tube placed on the electric heating tube seat 2 to fix the electric heating tube to be processed.

[0046] In order to further improve the reliability of pressing, the first cap pressing cylinder 51 can be started, and the first cap pressing cylinder 51 can drive the pressing plate 52 to move downward. At the same time, the first clamping cylinder 42 and the second clamping cylinder 44 are also started, so that the first clamp 41 and the second clamp 43 are separated. The first clamp 41 and the second clamp 43 no longer clamp the electric heating tube that needs to be pressed again. At this time, the various pressing needles 53 on the pressing plate 52 can press multiple rubber caps onto the above-mentioned electric heating tube again.

[0047] After the pressing is completed, the lifting cylinder 31 can be started again, so that the lifting cylinder 31 drives the electric heating tube base 21 to move downward, and then the user can remove the electric heating tube with the pressed rubber cap from the electric heating tube base 21 and proceed to the next processing.
