[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.

[0030] According to an embodiment of the utility model, on the one hand, a feeding mechanism is provided, which includes: a feeding device 1, having a turntable 11 and a first driving member 12; the turntable 11 stores sealing strips 9 to be cut, and the sealing strips 9 are continuous strips and are coiled and stacked on the turntable 11.

[0031] The first traction device 2 has a second driving member 22, a clamping wheel 23 and a driving wheel 24; the clamping wheel 23 and the driving wheel 24 are respectively arranged on opposite sides of the sealing strip 9 in the radial direction, and clamp the sealing strip 9; the driving wheel 24 is coaxially fixed with the output shaft of the second driving member 22, and the second driving member 22 drives the driving wheel 24 to rotate; the first traction device 2 also has a fourth driving member 25; the clamping wheel 23 is rotatably connected to the bracket 26, the output shaft of the fourth driving member 25 is fixedly connected to the bracket 26, the fourth driving member 25 drives the bracket 26 to move, and the bracket 26 drives the clamping wheel 23 to approach or move away from the driving wheel 24, so that the clamping wheel 23 clamps or loosens the sealing strip 9.

[0032] After the sealing strip 9 is led out from the first traction device 2, the strip body is surrounded to form at least one material storage buffer portion 3; the material storage buffer portion 3 has a free side 31. In this embodiment, the free side 31 is a part of the strip body located at the bottom of the material storage buffer portion 3. The sealing strip 9 at the free side 31 has no other structural constraints and is used to reflect the material storage amount of the material storage buffer portion 3; specifically, when the material storage amount of the material storage buffer portion 3 is too large, the sealing strip 9 will relax and the height of the free side 31 will decrease. When the material storage amount of the material storage buffer portion 3 is too small, the sealing strip 9 will be tightened and the height of the free side 31 will increase.

[0033] The second traction device 4 has a second roller 41 and a third driving member 42; the second roller 41 abuts against a portion of the sealing strip at the material storage buffer portion 3, and the second roller 41 is coaxially connected to the output shaft of the third driving member 42, and the third driving member 42 drives the second roller 41 to rotate, and the second roller 41 pushes the sealing strip 9 forward.

[0034] The specific use process of the feeding mechanism is as follows: the continuous sealing strip 9 passes through the first traction device 2, and the pressure wheel 23 in the first traction device 2 moves toward the direction close to the driving wheel 24 under the action of the fourth driving member 25, so that the pressure wheel 23 and the driving wheel 24 are clamped on both sides of the sealing strip 9, and the third driving member 42 rotates the driving wheel 24, and the friction force is generated between the driving wheel 24 and the sealing strip 9 due to the extrusion and relative movement, and the sealing strip 9 moves forward under the action of the friction force; the pressure wheel 23 passively rotates and always remains pressed on the sealing strip 9; after the sealing strip 9 is sent out from the first traction device 2, a material storage buffer part 3 is formed around the strip body, and the sealing strip 9 at the material storage buffer part 3 passes through the second traction device 4, and the second roller 41 in the second traction device 4 contacts the sealing strip 9, and the second roller 41 is driven by the third driving member 42 to rotate actively, thereby pushing the sealing strip 9 forward; the sealing strip 9 enters the cutting mechanism 8, and the cutting assembly 82 in the cutting mechanism 8 cuts the continuous sealing strip 9 to obtain a finished sealing strip.

[0035] The use process of the feeding mechanism also includes that a first detection member 54 is provided at a position of the feeding mechanism close to the free side 31, and the first detection member 54 is electrically connected to the second driving member 22, and the first detection member 54 is used to detect the height of the free side 31 of the material storage buffer 3, and to obtain the storage amount in the material storage buffer 3 according to the height of the free side 31; if the height of the free side 31 is lower than a certain value A, it means that the storage amount in the material storage buffer 3 is too large and reaches the upper limit of the storage, so that the sealing strip 9 has a certain degree of slack, and the second driving member 22 stops, and the driving wheel 24 temporarily no longer plays a driving role, and the driving wheel 24 becomes a passive rotation conveyor, and only relies on the third driving member 42 and the second roller 41 to drive the sealing strip 9 forward to slow down the feeding, reduce the feeding, eliminate the slackness of the sealing strip 9, and the sealing strip 9 is in a natural state; when the height of the free side 31 When it is higher than a certain value B, it means that the storage amount in the storage buffer 3 is too small and reaches the lower limit of the storage amount, causing the sealing strip 9 to be tensioned to a certain extent. The first driving member 12 and the second driving member 22 are started and drive the driving wheel 24 to rotate. The driving wheel 24 rotates to drive the sealing strip 9 forward to increase the feeding. With the increase of feeding, the tension of the sealing strip 9 is eliminated and the sealing strip 9 is in a natural state. In summary, the first detection member 54, the free side 31 and the second driving member 22 cooperate with each other. When the storage amount in the storage buffer 3 is too small or too large during the conveying process of the sealing strip 9, the sealing strip 9 will be tensioned or relaxed. The feeding device 1 can automatically adjust the feeding speed to eliminate the overflow or insufficient storage amount in the storage buffer 3, thereby eliminating the bad state of the sealing strip 9, ensuring that the sealing strip 9 is always in a natural state, and further ensuring the dimensional stability of the finished sealing strip.

[0036] In this embodiment, a driving wheel 24, a pressing wheel 23 and a second roller 41 are arranged at the conveying path of the sealing strip 9, and the sealing strip 9 is driven forward by the friction between the roller and the sealing strip 9. At the same time, a material storage buffer 3 formed by the sealing strip 9 is arranged. The height of the free side 31 of the material storage buffer 3 is used to reflect the amount of material stored in the material storage buffer 3, and then the real state of the sealing strip 9 during the conveying process is reflected. When the sealing strip 9 has a certain degree of relaxation or tension, the material feeding is timely slowed down or increased, thereby eliminating the relaxation or tension, and the material storage under the action of the double angle is maintained. The sealing strip 9 is ensured to be in a natural state at all times, so that the sealing strip 9 is not stretched or deformed during the feeding process and the size of the finished sealing strip is stable, thereby effectively improving the production accuracy and efficiency. The sealing strip 9 is driven forward by rotating the roller, so that the forward speed of the sealing strip 9 is increased while ensuring that the sealing strip 9 is almost not stretched. The cooperation of the material storage buffer 3, the first detection member 54 and the second driving member 22 ensures that the sealing strip 9 is always in a natural state during the feeding process. The roller and the material storage buffer 3 provide double insurance for the feeding process of the sealing strip 9, ensuring that the fixed-length cutting production of the sealing strip 9 is carried out smoothly.

[0037] The use process of the feeding mechanism also includes that after the sealing strip 9 is fed out from the feeding device 1, it first passes through the feeding operating device 7, and the feeding operating device 7 can ensure that the fed sealing strip 9 is in the correct position without deflection during the forward movement; the second detection member 72 in the feeding operating device 7 can detect the angle of the sealing strip 9, and the second detection member 72 is electrically connected to the first driving member 12, and the second detection member 72 can control the movement of the turntable 11 with the help of the first driving member 12; if the sealing strip 9 is deflected, the second detection member 72 can obtain the deflection direction and angle of the sealing strip 9, and control the movement of the turntable 11 according to the deflection direction and angle, and the turntable 11 rotates and drives the sealing strip to rotate to eliminate the deflection and ensure that the fed sealing strip 9 moves forward in the correct position.
