[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0029] Reference Figures 1 to 6 As shown, a feeding device for gaskets of a glue needle machine comprises a mounting seat 1, a knife seat 2, and a baffle plate 3 connected in sequence, wherein the baffle plate 3 is provided with a pin slot 31, and the mounting seat 1 is provided with a pushing module 11, and the pushing module 11 pushes the gasket into the pin slot 31; a gap is left between the knife seat 2 and the baffle plate 3, a blade 4 is rotatably provided on the knife seat 2, and the blade 4 is located in the gap, and a first cylinder 12 is provided at one end of the mounting seat 1 away from the knife seat 2, and the output end of the first cylinder 12 can move horizontally, and a chamber 13 is provided in the mounting seat 1, and a transmission mechanism 14 is provided in the chamber 13, and the transmission mechanism 14 is transmission-connected with the output end of the first cylinder 12 and the blade 4, so that the blade 4 can swing and cut the gasket;

[0030] During use: when the pushing module 11 on the mounting seat 1 pushes the gasket into the pin slot 31 of the baffle 3, the first cylinder 12 will start and move horizontally, which will cause the transmission mechanism 14 in the chamber 13 to swing, thereby driving the blade 4 on the knife seat 2 to swing to cut the gasket, thereby completing the separation of the gasket. After the gasket cutting is completed, the first cylinder 12 is reset to reset the transmission mechanism 14, thereby driving the blade 4 to reset, thereby preparing for the cutting and separation of the next gasket; by adopting a horizontal arrangement, there is no need to reserve enough space under the knife seat 2 to install the first cylinder 12 and the transmission mechanism 14, thereby improving the utilization of space and facilitating the installation of workers.

[0031] Preferably, the knife seat 2 is provided with a track groove 21, and the track groove 21 is used to cooperate with the baffle 3 to form a gap;

[0032] By providing a track groove 21 on the knife seat 2, the track groove 21 cooperates with the baffle 3 to form a gap, and the blade 4 is hinged on the knife seat through a rotating shaft, and the blade 4 is located in the gap. In this way, when the output end of the first cylinder 12 moves horizontally, the transmission mechanism 14 will move in the track groove 21, and the blade 4 is hidden in the gap, which can avoid the blade 4 from colliding with other objects and extend the service life of the blade 4.

[0033] Preferably, the track groove 21 is provided with a waist-shaped hole, and one end of the transmission mechanism 14 passes through the waist-shaped hole and is connected to the blade 4;

[0034] Furthermore, the blade 4 also has a waist-shaped hole 211 that matches the waist-shaped hole 211 in the trajectory groove 21. The two waist-shaped holes 211 are arranged in a cross, and can better guide the swing of the transmission mechanism 14 by cooperating with each other, ensuring that the connecting rod 141 can move along the path of the waist-shaped hole 211, and can also play a limiting role.

[0035] In this embodiment, the transmission mechanism 14 includes a connecting rod 141, an elastic component 142, and a wedge block 143 arranged on the output end of the first cylinder 12, the middle part of the connecting rod 141 is hinged to the bottom of the chamber 13, one end of the connecting rod 141 passes through the waist-shaped hole 211 and is connected to the blade 4, the elastic component 142 connects the end of the connecting rod 141 away from the blade 4 and the upper wall of the chamber 13, and the end of the connecting rod 141 away from the blade 4 rests on the wedge block 143;

[0036] The first cylinder 12 drives the wedge block 143 to move horizontally to allow the connecting rod 141 to swing;

[0037] The wedge block 143 has an inclined surface, which is inclined downward in a direction close to the blade seat 2, and the end of the connecting rod 141 away from the blade 4 rests on the inclined surface;

[0038] Specifically, when cutting the gasket, the first cylinder 12 drives the wedge block 143 to move horizontally. Since the end of the connecting rod 141 in the chamber 13 away from the blade 4 is placed on the inclined surface of the wedge block 143, when the wedge block 143 moves horizontally, the end of the connecting rod 141 placed on the inclined surface will swing upward and compress the elastic component 142, while the end connected to the blade 4 will swing downward along the path of the waist-shaped hole 211, thereby driving the blade 4 to swing and cut the gasket in the pin slot 31. After the cutting is completed, the first cylinder 12 drives the wedge block 143 to reset. At the same time, the elastic component 142 resets the connecting rod 141 to apply force downward to the end of the connecting rod 141 close to the wedge block 143 to reset the connecting rod 141, thereby preparing for the cutting of the next gasket.

[0039] In this embodiment, the connecting rod 141 is provided with a first arcuate surface 1411, and the end surface of the connecting rod 141 close to the wedge block 143 is transitionally connected to the bottom surface of the connecting rod 141 through the first arcuate surface 1411; the wedge block 143 is provided with a second arcuate surface 1431, and the end surface of the wedge block 143 close to the connecting rod 141 is transitionally connected to the top surface of the wedge block 143 through the second arcuate surface 1431;

[0040] Specifically, the end of the connecting rod 141 away from the blade 4 is placed on the wedge block 143, that is, the first arc surface 1411 and the second arc surface 1431 are in contact with each other. Then, when the first cylinder 12 drives the wedge block 143 to move horizontally and then drives the connecting rod 141 to swing, the wedge block 143 continues to move forward, and the end of the connecting rod 141 placed on the wedge block 143 will continue to swing upward along the second arc surface 1431 and compress the elastic component 142. The mutual contact between the two arc surfaces reduces the contact area between each other, reduces the friction, and makes the connecting rod 141 become smoother when swinging.

[0041] Preferably, the elastic component 142 is a first spring; the first spring is used to reset the connecting rod 141, thereby continuously cutting the gasket.

[0042] More preferably, the pusher module 11 includes a second cylinder 111 and a slider 112 arranged on the output end of the second cylinder 111, the second cylinder 111 is located at one end of the mounting seat 1 away from the knife seat 2, the first cylinder 12 and the second cylinder 111 are arranged side by side, a material shifting block 113 is rotatably arranged on the slider 112, a feeding cutter head 114 is arranged on the material shifting block 113, the slider 112 has an assembly groove 115, the material shifting block 113 is located in the assembly groove 115, and a second spring (not shown in the figure) is arranged between one end of the material shifting block 113 away from the feeding cutter head 114 and the assembly groove 115;

[0043] Specifically, the material shifting block 113 is rotatable and is powered by the second cylinder 111. When the material shifting block 113 moves away from the end of the pin slot 31, the second spring is compressed. When the material shifting block 113 moves toward the end close to the pin slot 31, the second spring is reset and the feeding cutter head 114 is inserted into the hole of the gasket. Moreover, the first cylinder 12 and the second cylinder 111 are arranged side by side, which can better improve the utilization of space.

[0044] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
