[0045] A zipper machine is a device used to manufacture zippers. The wire is supplied to a zipper tooth implanting machine through a wire supply device, and the zipper tooth implanting machine then combines the wire and the tape together to manufacture a zipper.

[0046] The wire feeding device generally includes a base and a motor disposed on the base. A bobbin with wires wound on it is placed on the base, and the motor drives the bobbin to rotate to release the wires in sequence.

[0047] A zipper tooth implanting machine generally includes a wire feeding device for intermittently feeding the wire, a chain belt feeding device for intermittently feeding the chain belt, an engaging device for forming the wire into chain teeth and engaging the chain teeth with the chain belt to form a chain belt, and a chain belt feeding device for feeding the chain belt out.

[0048] When replacing the spool, the old spool is manually lifted off the base, and the new spool (with wire) is then lifted and placed on the base. However, since the spool with wire is heavy, especially when the spool has metal wire, it often weighs more than 100 kilograms, so replacing the entire spool is time-consuming and laborious, and it is easy to cause safety problems.

[0049] In order to solve this technical problem, the present application provides a wire feeding device 1, which can be used to replace the wire spool more conveniently and efficiently.

[0050] The wire feeding device 1 of the present application includes: a base 11, which includes a left frame 111, a right frame 112, and a front frame 113; two support rollers 12, the two ends of the support rollers 12 are respectively connected to the left frame 111 and the right frame 112, the support rollers 12 are arranged in the left-right direction and the two support rollers 12 are spaced apart in the front-back direction to form a wire bearing support position 13; wherein the front frame 113 has a front side inclined surface 1131, and under the action of external force, the wire spool can enter the wire bearing support position 13 through the front side inclined surface 1131.

[0051] Compared with the prior art, the wire feeding device 1 of the present application sets a front inclined surface 1131 on the front frame 113 to allow the wire spool to pass through and enter the wire bearing support position 13 under the action of external force. When in use, the operator only needs a small force to push the wire spool through the front inclined surface and roll into the wire bearing support position 13 of the base 11, making the replacement of the wire spool more convenient and efficient.

[0052] Among them, in the present application, the left frame 111 and the right frame 112 are both provided with installation spaces 1111 and 1121, and the installation spaces 1111 and 1121 are provided with bearing seats 1112 and 1122, and the support roller 12 is connected to the bearing seats 1112 and 1122; the base 11 has a top surface 114, and the top surface 114 is located on the first plane a, and the bearing seat 1112 is located below the first plane a.

[0053] By setting the bearing seat 1112 at a position lower than the first plane a, the height of the line bearing support 13 formed by the two support rollers 12 can be at least lower than the top surface 114 of the base 11. At this time, the third plane c where the two support rollers 12 are located is lower than the first plane a, or is flush with the first plane a. Of course, it is also feasible that the third plane c formed is slightly higher than the first plane a. When replacing the bobbin, under the action of external thrust such as that of an operator, the bobbin can roll directly into the line bearing support 13 through the front inclined surface 1131. At this time, the climbing height of the bobbin on the base 11 is less than the thickness of the base 11, and the operation is more convenient and labor-saving.

[0054] In order to allow the spool to enter the spool bearing support 13 more easily, the front inclined surface 1131 is further provided with a spool entrance 11311, and the spool entrance 11311 is located on the second plane b, and the first plane a is higher than the second plane b, thereby shortening the climbing distance of the spool.

[0055] The two support rollers 12 are located on the third plane c, and the second plane b is higher than the third plane c, so that the bobbin can more easily enter the bobbin support position 13 after passing through the bobbin entrance 11311. Due to the reduced height, it can save more effort.

[0056] In order to allow the spool to enter the spool bearing support 13 more easily, the base 11 has a bottom surface 115; the bottom surface 115 is recessed upward to form a mounting groove 116, and a supporting foot 117 is provided in the mounting groove 116, so that the bottom surface 115 is at a distance L from the placement plane, thereby further reducing the distance from the spool bearing support 13 to the placement platform, that is, reducing the height, making it easier for the spool to enter the supporting platform.

[0057] Preferably, the support foot 117 is a roller 1171, or the support foot 117 is a roller 1171 and the distance from the bottom surface 115 to the placement plane is smaller than the radius R of the roller 1171. The distance from the linear bearing support 13 to the placement platform is further reduced.

[0058] The wire supply device 1 of the present application further includes: a support column 14 , which is disposed on the base 11 ; a rotary arm 15 , which is disposed on the support column 14 , and a wire wheel 151 and a weight 152 are respectively disposed at both ends of the rotary arm 15 .

[0059] One end of the support roller 12 is connected to a transmission wheel 121, and the transmission wheels 121 of the two support rollers 12 are connected through a transmission member 122; under the action of the driving device, the two support rollers 12 rotate synchronously to drive the bobbin placed in the bobbin support position 13 to rotate. The transmission wheel 121 can be a sprocket, a pulley, a gear, etc., and the driving device can be a motor, an electric motor, etc. The transmission member 122 can be a belt, a chain, etc.

[0060] When the driving device is working, the spool rotates to release the wire wound on the spool, the force applied by the wire on the wire wheel 151 is reduced, and the swing arm 15 rotates under the action of the weight until a stop signal is triggered to control the driving device to stop working.

[0061] As the zipper tooth implanting machine 2 continues to feed the wire, the wire is gradually tightened, the force applied by the wire to the wire wheel 151 gradually increases, and the swing arm 15 rotates in the opposite direction until a start signal is triggered to control the drive device to start working. This reciprocating process allows the wire feeding device 1 to achieve intermittent wire release.

[0062] Specifically, in some embodiments, this can be achieved by presetting the working time and the preset stop time. When the driving device is working, the spool rotates to release the wire wound on the spool, and the force exerted by the wire on the wire wheel 151 is reduced. The arm 15 rotates to the preset stop position under the action of the weight. At the preset stop position, a stop signal will be triggered to control the driving device to stop working. As the zipper tooth implanting machine 2 continues to feed the wire, the wire is gradually tightened, and the force exerted by the wire on the wire wheel 151 gradually increases, and the cantilever 15 rotates in the opposite direction until it reaches the preset start position. At the preset start position, a start signal will be triggered to control the driving device to start working. The wire feeding device 1 continues to release the wire to achieve intermittent release. The triggering and control of the driving device at the preset stop position and the preset start position can be achieved through a travel switch or a sensor.

[0063] In other embodiments, it can also be achieved by presetting the working time and the stopping time. When the driving device is working, the bobbin rotates to release the wire wound on the bobbin, and the force exerted by the wire on the wire wheel 151 is reduced. The swing arm 15 rotates under the action of the weight until the preset working time is over, triggering the generation of a stop signal to control the driving device to stop working. Entering the preset stop time, as the zipper tooth implanting machine 2 continues to feed the wire, the wire is gradually tightened, and the force exerted by the wire on the wire wheel 151 gradually increases. The cantilever 15 rotates in the opposite direction until the preset stop time is over, triggering the generation of a start signal to control the driving device to start working. The wire supply device 1 continues to release the wire to achieve intermittent release.

[0064] like Figure 1 As shown, a wire feeding device 1 provided in an exemplary embodiment of the present application includes: a base 11, two support rollers 12, a support column 14 and a rotary arm 15.

[0065] like Figure 2 , Figure 3As shown, the base 11 includes a top surface 114 and a bottom surface 115, and the top surface 114 is located on the first plane a. Specifically, the base includes a left frame 111, a right frame 112, a front frame 113, and a rear frame. The inner side surface of the left frame 111 is recessed outward to form the installation space 1111, and the inner side surface of the right frame 112 is recessed outward to form the installation space 1121. In other embodiments, the installation spaces 1111 and 1121 can also be formed by the top surfaces 114 of the left frame 111 and the right frame 112 being recessed downward, and the installation spaces 1111 and 1121 on the left frame 111 and the right frame 112 have holes in the axial direction of the support roller 12 suitable for the support roller to pass through.

[0066] like Figure 4 As shown, the front side surface of the front frame 113 is an inclined surface to form the front inclined surface 1131, and a bobbin entrance 11311 is provided on the front inclined surface 1131. The bobbin entrance 11311 is located on the second plane b.

[0067] The bottom surface 115 of the front frame 113 is recessed upward to form a mounting groove 116, and the bottom surface 115 of the rear frame is also recessed upward to form a mounting groove 116. A roller 1171 is provided in the mounting groove 116. As shown in the figure, four rollers 1171 are provided. And the distance L from the bottom surface 115 of the base 11 to the placement plane is less than the radius R of the roller 1171.

[0068] In other embodiments, the mounting groove 116 may also be provided on the bottom surface 115 of the left frame 111 and the right frame 112, the bottom surface 115 of the left frame 111, the right frame 112 and the front frame 113, and the bottom surface 115 of the left frame 111, the right frame 112 and the rear frame.

[0069] The two ends of the support roller 12 are respectively connected to the left frame 111 and the right frame 112, and the support roller 12 is arranged in the left-right direction and the two support rollers 12 are arranged at intervals in the front-back direction to form a linear bearing support 13. The two support rollers 12 are located in the third plane c. It should be understood that the third plane c is the plane where the highest point of the support roller 12 in the vertical direction is located.

[0070] In this embodiment, the first plane a is higher than the second plane b, and the second plane b is higher than the third plane c.

[0071] like Figure 5 , Figure 6As shown, in the installation spaces 1111 and 1121 of the left frame 111 and the right frame 112, bearing seats 1112 and 1122 are provided, the support roller 12 is connected to the bearing seats 1112 and 1122, one end of the support roller 12 is connected to a sprocket, and the sprockets of the two support rollers 12 are connected by a chain; the motor is also driven and connected to one of the support rollers by means of a sprocket and a chain, and under the action of the motor, the two support rollers 12 rotate synchronously to drive the rotation of the wire shaft placed in the wire bearing support position 13.

[0072] like Figure 7 As shown, further, in order to prevent the spool from axially deviating along the support roller 12 during rotation, flanges 123 are provided at both ends of the support roller 12 in this embodiment, and the flanges 123 protrude from the inner side surface of the left frame 111 or the right frame 112.

[0073] When the bobbin needs to be replaced, the operator applies an external force to push the bobbin, which enters the bobbin entrance 11311 through the front inclined surface 1131, and then enters the bobbin support surface 13, so that the bobbin is placed between the two support rollers 12. The entire operation process is convenient and efficient, and is much more labor-saving and safer than the existing technology.

[0074] like Figure 8 As shown, the support column 14 is arranged on the top surface 114 of the base 11, specifically, on the left frame 111 or the right frame 112 or the rear frame.

[0075] The rotary arm 15 is disposed on the support column 14 , and a wire wheel 151 and a weight 152 are respectively disposed at two ends of the rotary arm 15 .

[0076] When the drive device is working, the spool rotates to release the wire wound on the spool, and the force exerted by the wire on the reel 151 is reduced. The arm 15 rotates to the preset stop position under the action of the weight 152. At the preset stop position, a stop signal is triggered to control the drive device to stop working. As the zipper tooth implanting machine 2 continues to feed wire, the wire is gradually tightened, and the force exerted by the wire on the reel 151 gradually increases, and the cantilever 15 rotates in the opposite direction until it reaches the preset start position. At the preset start position, a start signal is triggered to control the drive device to start working. The wire feeding device 1 continues to release the wire to achieve intermittent release. The triggering and control of the drive device at the preset stop position and the preset start position can be achieved through a travel switch or a sensor.

The zipper machine also includes: a frame 3, which includes an upper installation space 31 and a lower installation space 32, a zipper tooth implanting machine 2, which is arranged in the upper installation space 31; and two wire feeding devices 1, which are arranged in the lower installation space 32.

[0078] Preferably, a first pre-fixing member 33 is provided on the frame 3 , and a second pre-fixing member 16 cooperating with the first pre-fixing member 33 is provided on the base 11 .

[0079] When the old bobbin needs to be replaced, the wire feeding device 1 of the present application is pulled out from the lower installation space 32. Due to the setting of the roller, the whole operation is labor-saving. When replacing a new bobbin, firstly, the second pre-fixing member 16 is used to pre-fix the matching fixing member with the first pre-fixing member 33 on the frame 3, and then a thrust is applied to push the wire into the wire bearing support position. Then the pre-fixing state is released, and the wire feeding device is pushed into the lower installation space.
