[0016] The following is a detailed description of this design solution with reference to the drawings:

[0017] A special maintenance auxiliary device for a press includes a lead screw 4, a baffle 5, a stop block 6, and a lead screw hole 7. There are three baffles 5, which are evenly distributed on the top surface of the plunger head 1 and fixedly connected thereto. Half of the baffle 5 is fixedly connected to the plunger head 1, and the other half is in movable contact with the top surface of the paste cylinder 9. The plunger head 1 is in movable contact with the paste cylinder 9. Both the main cylinder head 2 and the plunger head 1 are provided with two lead screw holes 7 and are communicated. The hole in the main cylinder head 2 is provided with a thread for fixing the lead screw 4 to be fixedly connected to the main cylinder head 2. There are two lead screws 4, both of which are in sliding contact with the two lead screw holes provided inside the plunger head 1. The bottoms of the two lead screws 4 are provided with threads and are threadedly connected to the lead screw holes 7 provided inside the main cylinder head 2. The top end of the lead screw 4 is fixedly connected to the middle of the bottom of the stop block 6;

[0018] In some embodiments, one end of the main cylinder rod 3 is fixedly connected to the main cylinder head 2. The main cylinder rod 3 drives the main cylinder head 2 to move synchronously. The main cylinder head 2 is provided with a lead screw hole 7 threadedly connected to the lead screw 4 and drives the lead screw 4 to move synchronously;

[0019] In some embodiments, when the plunger head 1 is separated from the main cylinder head 2, when the plunger head 1 makes a return movement in the main cylinder head 2, it abuts against the top surface of the paste cylinder 9 through the baffle 5, so that the plunger head 1 is separated from the main cylinder head 2;

[0020] In some embodiments, when the stop block 6 provided at the top of the lead screw abuts against the top surface of the plunger head 1, the bottom of the stop block 6 is fixedly connected to the top surface of the plunger head 1. When the plunger head 1 makes a forward movement in the main cylinder head 2, the plunger head 1 is pushed out by driving the lead screw 4;

[0021] In some embodiments, the center of the baffle 5 and the lead screw 4 are located on the same central axis to prevent the lead screw 4 from shifting when the main cylinder head 2 reciprocates;

[0022] In some embodiments, the length of the lead screw 4 is longer than the total length of the lead screw hole 7 provided in the plunger head 1, the lead screw hole 7 provided in the main cylinder head 2, and the electric heating rod 8, so that the length of the lead screw 4 is sufficient to completely take out the plunger head 1 and replace the electric heating rod 8.

[0023] Working principle:

[0024] Combined with Figure 1-2 As shown, the working principle and usage process of the present utility model are as follows: First, the two lead screws 4 are respectively passed through the two lead screw holes provided on the plunger head 1, and then the thread provided at one end of the lead screw 4 is connected to the thread of the lead screw 4 hole provided in the main cylinder head 2. One end of the three baffles 5 provided on the top surface of the plunger head 1 is fixedly connected to the plunger head 1, and the other half abuts against the top surface of the paste cylinder 9. By the return movement of the main cylinder rod 3, the main cylinder head 2 is driven to move synchronously. Due to the thread provided in the main cylinder head 2, the lead screw 4 is driven to move. The lead screw 4 slides and contacts in the lead screw hole 7 provided in the plunger head 1. There are three baffles 5 provided on the top surface of the plunger head 1, and the other half of the baffle 5 abuts against the paste cylinder 9, so that the plunger head 1 is separated from the main cylinder head 2.

[0025] When the block 6 provided at the top end of the lead screw 4 abuts against the top end of the plunger head 1, after the bottom of the block 6 is fixedly connected to the top surface of the plunger head 1, when the main cylinder rod 3 makes a forward movement, the lead screw 4 is driven to move synchronously. The thread provided at the bottom end of the lead screw 4 is threadedly connected to the main cylinder head 2, and the block 6 provided at the top end of the lead screw 4 is fixedly connected to the top surface of the plunger head 1. By the forward movement of the main cylinder rod 3, the plunger head 1 is driven to move synchronously, so that it is pushed out of the paste cylinder 9, and thus the electric heating rod 8 can be replaced.
