[0041] The following will describe the present experimental novelty in detail with reference to the accompanying drawings:

[0042] Figure 1-7 A full-automatic phenolic paper tube tube-removing machine of the present utility model is shown, including:

[0043] A base 10, on which a rotating motor 11 is evenly arranged;

[0044] A support frame 20, which is arranged on the base 10;

[0045] A telescopic rod 30, which is arranged at the center of the base 10;

[0046] A tube core 40, which is sleeved inside the support frame 20. The top end of the tube core 40 is detachably connected to the telescopic rod 30, the lower end of the tube core 40 is in contact connection with the rotating motor 11 of the base 10, and a phenolic paper tube 50 is sleeved on the outer wall of the tube core 40.

[0047] Working principle:

[0048] The specific steps of the tube-removing operation of the present utility model for the phenolic paper tube are as follows. First, the bottom end of the made phenolic paper tube 50 and the tube core 40 are clamped into the rotating motor 11 to complete the contact connection. Then, the outer wall of the phenolic paper tube 50 is fixed on the base 10 through the support frame 20. The way that the top end of the tube core 40 is detachably connected to the telescopic rod 30 is bolt fixation;

[0049] During operation, the rotating motor 11 drives the tube core 40 to rotate, and the telescopic rod 30 stretches and reciprocates up and down to make the phenolic paper tube 50 fall off the tube core 40;

[0050] This equipment simulates manual pulling, places the tube core 40 vertically, and realizes the phenolic paper tube detube operation by rotating and stretching back and forth. The fully automated design reduces the error of manual operation and saves time and effort to complete the phenolic paper tube detube operation.

[0051] As in the above solution, the structure of the base 10 includes:

[0052] A plurality of grooves 12 are evenly distributed on the base 10;

[0053] The rotating motor 11 is fixed in the groove 12 . A rectangular stopper 110 is provided on the motor shaft of the rotating motor 11 . The rectangular stopper 110 is sleeved and connected with the bottom end of the tube core 40 .

[0054] Working principle:

[0055] The bottom end of the tube core 40 is directly sleeved with the rectangular stopper 110 on the motor shaft of the rotating motor 11. Since only the tube core 40 is connected to the motor shaft of the rotating motor 11, and the phenolic paper tube 50 on the outer wall of the tube core 40 is fixed by the support frame 20, when the rotating motor 11 starts to rotate, it will drive the tube core 40 to rotate in the phenolic paper tube 50, and the bonded inner wall of the phenolic paper tube 50 and the outer wall of the tube core 40 are separated little by little, completing the first step of removing the tube;

[0056] The utility model is provided with a plurality of grooves 12 for the purpose of simultaneously performing the tube removal operation on a plurality of tube cores. In actual use, grooves 12 with different radii can be provided according to different models to perform the tube removal operation on phenolic paper tubes of different sizes.

[0057] As in the above solution, the structure of the support frame 20 includes:

[0058] A support rod 21, which is fixed on the base 10, and the support rod 21 is symmetrically arranged on both sides of the groove 12;

[0059] The semi-arc fixing frame 22 is sleeved on the support rod 21 , and protruding connection blocks 23 are symmetrically arranged at both ends of the semi-arc fixing frame 22 . The tube core 40 is bolted to the support frame 20 through the connection blocks 23 placed opposite to each other.

[0060] Working principle:

[0061] After the die 40 is sleeved in the groove 12 of the bottom plate 10, the semi-circular fixing frame 22 sleeved on the support rod 12 is moved to the middle of the phenolic paper tube 50 on the outer wall of the die 40 (in actual use, multiple semi-circular fixing frames 22 can be sleeved according to the length of the phenolic paper tube for limit fixing, or semi-circular fixing frames 22 with different radii can be sleeved according to phenolic paper tubes of different sizes for limit fixing. Other actual situations can vary according to on-site use, and will not be elaborated here).

[0062] The connecting block 23 is provided with a threaded through hole. By bolt-connecting two relatively placed connecting blocks 23, the outer wall of the phenolic paper tube 50 is fixed on the support frame 20, ensuring that the phenolic paper tube 50 does not shift during the tube removal operation of the phenolic paper tube 50. At the same time, the position of the phenolic paper tube 50 is fixed and limited from the outside, allowing the inner die 40 to fall off smoothly.

[0063] In the above solution, the structure of the telescopic rod 30 includes:

[0064] A telescopic main rod 31, which is fixed at the center of the circle of the base 10. An electric telescopic cylinder is arranged inside the telescopic main rod 31, and a plurality of extension rods 32 are evenly arranged at the top of the telescopic main rod 31;

[0065] A telescopic sub-rod 33, whose top is bolt-connected to the bottom end of the extension rod 32;

[0066] A rotary joint 34, with a thread arranged inside the protruding part in the middle. The rotary joint 34 is thread-connected to the telescopic sub-rod 33. Ear plates 341 with through holes are symmetrically arranged on both sides of the rotary joint 34, and the ear plates 341 are bolt-connected to the top end of the die 40.

[0067] In the above solution, the structure of the die 40 includes:

[0068] An upper groove 41, which is arranged at the center position of the top end of the die 40, and the upper groove 41 is in contact connection with the protruding part of the rotary joint;

[0069] Bolt holes 42, which are symmetrically arranged on both sides of the upper groove 41, and the bolt holes 42 are bolt-connected to the ear plates 341;

[0070] A rectangular groove 43, which is arranged at the bottom end of the die 40, and the limit block 110 of the rotary motor 11 is embedded in the rectangular groove 43 for movable connection.

[0071] Working principle:

[0072] The way the bottom end of the tube core 40 is in contact connection with the rotary motor 11 is that the rectangular groove 43 provided at the bottom end of the tube core 40 is adapted to the rectangular limit block 110 provided on the motor shaft of the rotary motor 11, so that the rectangular limit block 110 on the rotary motor 11 is directly embedded in the rectangular groove 43 to complete the connection, realizing that the lower end of the tube core 40 is fixed and driven to rotate by the rotary motor 11;

[0073] The detachable connection mode between the top end of the tube core 40 and the telescopic rod 30 is that the middle protruding part of the rotary joint 34 provided on the telescopic sub-rod 33 is sleeved in the upper groove 41 on the top end of the tube core 40, and then the ear plates 341 provided on both sides of the rotary joint 34 are bolt-connected with the bolt holes 41 on the top end of the tube core 40 to complete the fixation;

[0074] When starting the operation of removing the phenolic paper tube from the tube core, the electric telescopic cylinder in the telescopic main rod 31 starts to work, and is transmitted through the telescopic sub-rod 33 bolt-connected with the extension rod 32 (the way of spiral connection between the extension rod 32 and the telescopic sub-rod 33 can replace the telescopic sub-rod 33 according to the phenolic paper tubes of different length dimensions in actual use to meet the actual needs), and the tube core 40 starts to move up and down in a reciprocating manner, simulating the manual pulling method to gradually separate the phenolic paper tube from the tube core 40;

[0075] In this working process, due to the connection mode of the rotary joint 34 itself, the tube core 40 will not drive the telescopic sub-rod 33 to rotate during the self-rotation of the rotary motor 11, and the rotary motor 11 and the telescopic rod 30 cooperate with each other without affecting each other to complete the operation of removing the phenolic paper tube from the tube core.

[0076] Although the embodiments of the present invention have been disclosed above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those who are familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
