Description

Technical Field

[0001] The present invention relates to the field of mechanical design, and in particular to a heating wire feeding assembly. Background Art

[0002] Heating wires, also known as electric heating wires, generate heat when powered and are widely used in a variety of products, such as rice cookers, water heaters, and soymilk makers. The heat generated by a heating wire is greatly affected by its resistance. Therefore, most common heating wires are designed in a spiral shape to increase their length. At the same time, the cross-section of the heating wire is made very small to increase its resistance and thus ensure the heating effect of the heating wire.

[0003] In the past, heating wire feeding mostly relied on manual wire feeding, but manual wire feeding has low efficiency, high work intensity and high labor cost. In order to improve market competitiveness, mechanized wire feeding has begun to be used in the market. Due to the long length and small cross-section of the heating wire, when a large number of heating wires to be fed are placed, they are prone to displacement and are often difficult to distribute evenly, which brings difficulties to mechanized wire feeding. Moreover, most common machines cannot control the timing of wire output after the wire is fed into place. Once the wire is fed into place, the subsequent receiving mechanism fails and it is often impossible to effectively stop the wire output, which poses certain hidden dangers. Summary of the Invention

[0004] The object of the present invention is to provide a heating wire feeding assembly that can solve one or more of the above problems.

[0005] According to one aspect of the present invention, a heating wire feeding assembly is provided, comprising a wire clamping device, a conveying device, a shaking device, a wire outlet switch device, a wire loading platform and a wire feeding platform, wherein the shaking device is mounted on the wire loading platform, the wire outlet switch device is mounted on the wire feeding platform, the wire clamping device is mounted on the conveying device, and the conveying device is used to make the wire clamping device reciprocate between the wire loading platform and the wire feeding platform.

[0006] The beneficial effects of the present invention are as follows: in the present invention, the wire loading platform can be used to store the heating wire to be fed, and by providing a wire clamping device and a conveying device, the heating wire on the wire loading platform can be conveniently clamped and fed to the wire feeding platform, and by providing a shaking device, the heating wire on the wire loading platform can be shaken so that it can be evenly distributed in the wire loading platform, thereby facilitating the clamping of the wire clamping device and reducing problems such as mis-clamping or multiple clamping, and the wire output switch device can conveniently control the timing of the wire output of the heating wire on the wire feeding platform, improve the flexibility of the wire output time, and avoid the problem of continuous wire output when problems occur in the subsequent receiving mechanism. Therefore, the present invention has a high degree of automation, can realize the wire feeding of the heating wire, and has strong working reliability and flexibility.

[0007] In some embodiments, the wire clamping device includes a clamping mechanism, a first cylinder, and a mounting base, wherein the first cylinder is mounted on the mounting base and connected to the clamping mechanism. The provision of the first cylinder facilitates the movement of the clamping mechanism.

[0008] In some embodiments, the wire clamping device includes a guide post and a guide sleeve. One end of the guide post is connected to the clamping mechanism. The guide sleeve is mounted on a mounting base and sleeved onto the guide post. The guide post and guide sleeve can guide the movement of the clamping mechanism, thereby ensuring the reliable movement of the clamping mechanism.

[0009] In some embodiments, the clamping mechanism includes a fourth cylinder, a connecting rod, a first clamping arm, a second clamping arm, and a mounting plate, wherein the mounting plate is connected to the first cylinder, the fourth cylinder is mounted on the mounting plate, the fourth cylinder is connected to the connecting rod, and the first and second clamping arms are both connected to the connecting rod. Thus, the fourth cylinder can drive the opening and closing of the first and second clamping arms via the connecting rod to achieve the clamping or releasing action of the clamping mechanism.

[0010] In some embodiments, the clamping mechanism includes a limit block connected to the fourth cylinder. The limit block is provided with a first limit arm and a second limit arm, wherein the first limit arm is located outside the first clamping arm, and the second limit arm is located outside the second clamping arm. The provision of the limit block can limit the movement limit of the first and second clamping arms, thereby preventing damage to the mechanism caused by the movement of the first and second clamping arms.

[0011] In some embodiments, the conveying device includes a lead screw, a nut, a guide rod, and a conveyor frame. The lead screw and guide rod are both mounted on the conveyor frame, the lead screw and guide rod being arranged in parallel. The nut is mounted on the lead screw and sleeved on the guide rod, and the wire clamping device is mounted on the nut. Thus, rotation of the lead screw can achieve linear motion of the nut, and the wire clamping device mounted on the nut can follow the rotation, thus achieving linear motion of the wire clamping device. The guide rod can guide the movement of the nut to ensure accurate movement of the nut.

[0012] In some embodiments, the shaking device includes a second cylinder, a movable block, and a cylinder seat. The cylinder seat is mounted on a wire loading platform, which is provided with a wire loading trough. The second cylinder is mounted on the cylinder seat and connected to the movable block, which extends into the wire loading trough. The wire loading trough facilitates the loading of the heating wire, and the second cylinder drives the movable block to move within the wire loading trough to achieve shaking of the heating wire within the wire loading trough, thereby ensuring that the heating wire is evenly distributed within the wire loading trough.

[0013] In some embodiments, the wire outlet switch device includes a third cylinder, a rotating shaft, and a baffle. The third cylinder is mounted on the wire feeder and connected to the rotating shaft. The wire feeder is provided with a wire outlet. The baffle is mounted on the rotating shaft and covers the wire outlet. The wire outlet facilitates the outlet of the heating wire. When the heating wire is located on the baffle, the third cylinder can drive the rotating shaft to rotate, thereby changing the position of the baffle so that the baffle no longer covers the wire outlet, allowing the heating wire to be discharged. Thus, the user can control the operation of the third cylinder to control the wire outlet timing.

[0014] In some embodiments, the wire outlet switch device includes a connecting block, the rotating shaft is installed on the wire feeding platform, one end of the connecting block is sleeved on the rotating shaft, and the other end is connected to the third cylinder.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] refer to Figures 1 to 8 A heating wire feeding assembly of the present invention includes a wire clamping device 1, a conveying device 2, a shaking device 3, a wire outlet switch device 4, a wire loading platform 5 and a wire feeding platform 6.

[0026] The wire clamping device 1 can be a mechanical clamping and releasing device, a vacuum adsorption device, or an electromagnetic adsorption device. In this embodiment, the wire clamping device 1 includes a clamping mechanism 11, a first cylinder 12, and a mounting base 13. The clamping mechanism 11 includes a fourth cylinder 111, a connecting rod 112, a first clamping arm 113, a second clamping arm 114, and a mounting plate 115. The cylinder body of the first cylinder 12 is fixedly mounted on the mounting base 13 by bolts, and the piston rod of the first cylinder 12 is fixedly connected to the mounting plate 115 of the clamping mechanism 11 by threaded engagement, so that the first cylinder 12 can drive the mounting plate 115 to move. In addition, the first cylinder 12 can also be replaced by a motor conveying device.

[0027] The cylinder body of the fourth cylinder 111 is fixedly mounted on the mounting plate 115 by bolts, the piston rod of the fourth cylinder 111 is fixedly connected to the connecting rod 112 by bolts, and the first clamping arm 113 and the second clamping arm 114 are both hinged to the connecting rod 112 through connecting arms.

[0028] The clamping mechanism 11 also includes a limit block 116, which is fixedly connected to the cylinder body of the fourth cylinder 111 by bolts. A first limit arm 117 and a second limit arm 118 are provided on the limit block 116. The first limit arm 117 is located on the outside of the first clamping arm 113, and the second limit arm 118 is located on the outside of the second clamping arm 114. The first limit arm 117 can serve as the limit position of movement of the first clamping arm 113, and the second limit arm 118 can serve as the limit position of movement of the second clamping arm 114. The distance from the first limit arm 117 to the first clamping arm 113 and the distance from the second limit arm 118 to the second clamping arm 114 can be adjusted according to the diameter of the heating wire to be clamped, so that it can match the use of heating wires of different diameters.

[0029] The wire clamping device 1 also includes a guide post 14 and a guide sleeve 15. One end of the guide post 14 is fixedly connected to the mounting plate 115 of the clamping mechanism 11, and the guide sleeve 15 is fixedly mounted on the mounting base 13 by bolts. The guide sleeve 15 is sleeved on the guide post 14, and the guide post 14 is arranged parallel to the piston rod of the first cylinder 12.

[0030] The conveying device 2 includes a lead screw 21, a nut 22, a guide rod 23, and a conveying frame 24. The lead screw 21 is mounted on the conveying frame 24 via a bearing, allowing the lead screw 21 to rotate on the conveying frame 24. The guide rod 23 is fixedly mounted on the conveying frame 24 via a threaded fit, and the lead screw 21 and the guide rod 23 are arranged in parallel. The nut 22 is mounted on the lead screw 21 via a threaded fit, and the nut 22 is also sleeved on the guide rod 23. The mounting seat 13 of the wire clamping device 1 is fixedly mounted on the nut 22 via bolts. The conveying frame 24 of the conveying device 2 is located adjacent to the wire feeding platform 6. The conveying device 2 can be used to transport the wire clamping device 1 back and forth between the wire loading platform 5 and the wire feeding platform 6. In addition, the conveying device 2 can also be a conveying structure such as a rodless cylinder to transport the wire clamping device 1 back and forth between the wire loading platform 5 and the wire feeding platform 6.

[0031] The shaking device 3 can be an electromagnetic direct vibration device. In this embodiment, the shaking device 3 includes a second cylinder 31, a movable block 32, and a cylinder base 33. The cylinder base 33 is fixedly mounted on the wire loading platform 5 via bolts. The wire loading platform 5 is provided with a wire loading slot 51, which can be used to accommodate multiple heating wires. The cylinder body of the second cylinder 31 is fixedly mounted on the cylinder base 33 via bolts. The piston rod of the second cylinder 31 is fixedly connected to the movable block 32 via bolts. The side of the wire loading slot 51 is provided with a notch, and the movable block 32 extends through the notch into the wire loading slot 51.

[0032] The wire outlet switch device 4 includes a third cylinder 41, a rotating shaft 42, a baffle 43, and a connecting block 44. The cylinder body of the third cylinder 41 is fixedly mounted on the wire feeder 6 by bolts, and one end of the connecting block 44 is hinged to the piston rod of the third cylinder 41. The rotating shaft 42 is rotatably mounted on the wire feeder 6, and the other end of the connecting block 44 is fixedly sleeved on the rotating shaft 42. That is, the piston rod of the third cylinder 41 is connected to the rotating shaft 42 via the connecting block 44. The baffle 43 is fixedly mounted on the rotating shaft 42 by a hinge. The wire feeder 6 is provided with a wire outlet 61, and the baffle 43 covers the wire outlet 61.

[0033] When the present invention is in use, the screw 21 of the conveying device 2 can be fixedly connected to the external motor through a coupling, so that the external motor can drive the screw 21 to rotate. Multiple heating wires to be fed can be placed in the wire loading groove 51 on the wire loading platform 5, and the above-mentioned heating wires will also be located on the movable block 32.

[0034] When the heating wires need to be evenly distributed within the wire loading slot 51, the second cylinder 31 can be activated. The piston rod of the second cylinder 31 can drive the movable block 32 to reciprocate, thereby causing the heating wires located on the movable block 32 to vibrate. After a certain period of vibration, the heating wires can gradually be evenly distributed within the wire loading slot 51, facilitating subsequent transportation and facilitating the placement of as many heating wires as possible. In addition, both the shaking device 3 and the wire loading slot 51 can be provided in pairs, so that the two shaking devices 3 can respectively vibrate the heating wires in the two wire loading slots 51.

[0035] When wire feeding is required, the external motor can be started, which drives the screw 21 to rotate. The rotation of the screw 21 drives the nut 22 to make a linear motion, and the wire clamping device 1 connected to the nut 22 moves accordingly, moving the wire clamping device 1 to the wire loading platform 5 and positioning the clamping mechanism 11 on the wire loading groove 51. The guide rod 23 can guide the movement of the nut 22 to ensure the accuracy of the movement of the nut 22, thereby ensuring the accuracy of the movement of the wire clamping device 1.

[0036] When the first air cylinder 12 is activated again, the piston rod of the first air cylinder 12 can drive the clamping mechanism 11 to move downward, so that the clamping mechanism 11 is close to the heating wire in the wire loading groove 51. The guide post 14 can move with the movement of the clamping mechanism 11 and guide the movement of the clamping mechanism 11 to ensure the movement accuracy of the clamping mechanism 11.

[0037] At the same time, the piston rod of the fourth cylinder 111 extends and drives the connecting rod 112 to move so that the first clamping arm 113 and the second clamping arm 114 move away from each other. When a heating wire in the wire loading slot 51 is between the first clamping arm 113 and the second clamping arm 114, the piston rod of the fourth cylinder 111 retracts and drives the connecting rod 112 to move so that the first clamping arm 113 and the second clamping arm 114 move closer together until the first clamping arm 113 and the second clamping arm 114 clamp the heating wire.

[0038] Start the first cylinder again, and the piston rod of the first cylinder 12 can drive the clamping mechanism 11 to move upward, so that the clamping mechanism 11 is away from the wire loading groove 51. Then start the external motor again to rotate the screw 21 to move the wire clamping device 1 to the wire feeding platform 6, and make the clamping mechanism 11 located on the wire outlet 61. Then rely on the first cylinder 12 to make the clamping mechanism 11 move down to contact the baffle 43 on the wire outlet 61, and rely on the fourth cylinder 111 to release the first clamping arm 113 and the second clamping arm 114 from clamping the heating wire, so that the heating wire can be placed on the baffle 43.

[0039] On the other hand, the clamping mechanism 11 and the first cylinder 12 in the wire clamping device 1 can be set to two, and different first cylinders 12 can drive different clamping mechanisms 11 to perform clamping actions, so as to clamp two heating wires at the same time, thereby improving the working efficiency of the present invention.

[0040] When the wire needs to be drawn out, the third cylinder 41 can be started, and the third cylinder 41 can drive the rotating shaft 42 to rotate through the connecting block 44, so that the baffle 43 installed on the rotating shaft 42 also rotates, so that the baffle 43 no longer blocks the wire outlet 61, and the heating wire on the baffle 43 can fall out of the wire outlet 61, thereby achieving wire drawing. In this way, the wire drawing switch device 4 can control the timing of the wire drawing out of the wire outlet 61, and the wire drawing switch device 4 and the wire outlet 61 can be set to two, so that the two wire drawing switch devices 4 can respectively control the timing of the wire drawing out of the two wire outlets 61.

[0041] The heating wire feeding assembly of the present invention can achieve wire feeding and wire extraction of a large number of heating wires in the wire loading slot 51 by repeating the above-mentioned operations.

[0042] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
