Description

TECHNICAL FIELD

[0001] The utility model relates to the field of winding gasket manufacturing, especially to a pin type winding mechanism of winding gasket. BACKGROUND

[0002] In the production process of metal graphite winding gasket, one end of the steel belt needs to be connected to the winding wheel, so that the winding wheel can roll the steel belt when rotating. Currently, the method of connecting the steel belt to the winding wheel is to set a sheet-shaped slot on the surface of the winding wheel, and then insert one end of the steel belt into the slot. In this way, the winding wheel can roll the steel belt when rotating. However, with this connection method, after the winding gasket is produced, the end of the steel belt inserted into the slot will leave a redundant hook-shaped object, which needs to be removed by additional manual labor.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] As attached Figs. 1 to 3 The described pin-type winding mechanism for a wound gasket includes a winding wheel 1 and a top wheel 2 arranged opposite to each other. The winding wheel 1 can rotate actively, and a metal strip 3 is wound around the winding wheel 1 to form a wound gasket. In practical applications, the metal strip 3 is generally a steel strip, and the metal strip 3 and the graphite strip are wound together on the winding wheel 1 to form a metal-graphite wound gasket.

[0017] Pins 4 are provided on the surface of the winding wheel 1. Before winding the metal strip 3, as shown in the attached... Fig. 3 As shown, a connecting hole 5 is provided at one end of the metal strip 3. When it is necessary to wind the metal strip 3 onto the winding wheel 1, the pin 4 is inserted into the connecting hole 5 at one end of the metal strip 3. Then, when the winding wheel 1 rotates, the winding wheel 1 can wind the metal strip 3 through the engagement of the pin 4 and the connecting hole 5.

[0018] The winding wheel 1 has a hole 6 on its surface, and the depth direction of the hole 6 is radial to the winding wheel 1. The pin 4 is retractably disposed in the hole 6. After the winding pad is processed, the pin 4 can be retracted into the hole 6, so that the pin 4 is disengaged from the connecting hole 5 on the metal strip 3, making it convenient to remove the processed winding pad.

[0019] An elastic element 7 is provided between the pin 4 and the socket 6; under the elastic action of the elastic element 7, the pin 4 has a tendency to extend out of the socket 6; when the pin 4 retracts into the socket 6, it compresses the elastic element 7.

[0020] The elastic member 7 is a telescopic spring, and the elastic member 7 is arranged at the bottom of the insertion hole 6, as shown in the accompanying drawings. Fig. 2 As shown in the accompanying drawings, one end of the telescopic spring abuts against the bottom of the insertion hole 6, and the other end of the telescopic spring abuts against the insertion pin 4.

[0021] An adjusting sliding groove 8 is arranged on the side profile surface of the winding wheel 1, and the adjusting sliding groove 8 is in communication with the insertion hole 6. The adjusting sliding groove 8 is an elongated groove body, and the length direction of the adjusting sliding groove 8 is consistent with the depth direction of the insertion hole 6. One side of the insertion pin 4 is connected with an adjusting pin 9, and the adjusting pin 9 is correspondingly arranged in the adjusting sliding groove 8. Due to the existence of the adjusting pin 9, the insertion pin 4 will not be separated from the insertion hole 6 under the elastic force of the elastic member 7. In addition, when the adjusting pin 9 is displaced along the length direction of the adjusting sliding groove 8, the insertion pin 4 will be telescoped in the insertion hole 6. Workers can manually control the insertion pin 4 to be retracted into the insertion hole 6 through the adjusting pin 9, so as to conveniently take off the processed winding gasket.

[0022] One side of the insertion pin 4 is provided with a screw hole. One end of the adjusting pin 9 is provided with an external thread structure, and the end of the adjusting pin 9 is threadedly connected with the screw hole, so that the adjusting pin 9 is detachably connected with the insertion pin 4, and the insertion pin 4 is conveniently assembled into the insertion hole 6. In actual assembly, the telescopic spring is only needed to be firstly put into the insertion hole 6, and then the insertion pin 4 is put into the insertion hole 6. The insertion pin 4 is rotated, so that the screw hole on the insertion pin 4 is aligned with the adjusting sliding groove 8. Then the adjusting pin 9 is screwed into the screw hole, so that the insertion pin 4 is assembled on the winding wheel 1.

[0023] The top wheel 2 is movably arranged, and the top wheel 2 can be movably close to or away from the winding wheel 1. After the insertion pin 4 is inserted into the connecting hole 5, the top wheel 2 is close to the winding wheel 1, and the top wheel 2 is clamped and pressed with the winding wheel 1 to press the metal belt 3, so that the winding wheel 1 and the top wheel 2 cooperate to process the winding gasket.

[0024] The working mode of the utility model is as follows: when the metal graphite winding gasket needs to be processed, the connecting hole 5 is arranged at one end of the metal belt 3, then the insertion pin 4 on the winding wheel 1 is inserted into the connecting hole 5, the top wheel 2 is close to the winding wheel 1, then the winding wheel 1 is rotated and the metal belt 3 is wound, after the metal belt 3 is wound for many turns, one end of the graphite belt is inserted into the space between the metal belt 3 and the winding wheel 1, so that the graphite belt is also wound on the winding wheel 1, after the metal belt 3 and the graphite belt are wound for many turns, the graphite belt and the metal belt 3 are disconnected, so that the winding gasket is processed; the top wheel 2 is gradually away from the winding wheel 1 during the processing of the winding gasket; after the winding gasket is processed, the worker manually drives the adjusting pin 9, so that the insertion pin 4 is retracted into the insertion hole 6, and then the winding gasket is taken off. Compared with the prior art, the utility model can save the process of manually removing the residual hook-shaped object, so that the labor is saved.

[0025] The above merely is the preferred implementation form of the present application, and it should be noted that for the ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
