DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0027] In the description of the present invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] In the description of the present invention, it should be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be intermediate elements at the same time. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0029] In one embodiment, see Figures 1 to 5 A wire drawing mechanism 100 comprises: a sliding assembly 110, a floating plate 120, and a connecting rod assembly 130, wherein the floating plate 120 is slidably arranged on the sliding assembly 110, and the connecting rod assembly 130 is rotatably connected to the sliding assembly 110; a first motor 141, a first reducer 142, a first bearing seat 143, a wire drawing wheel 144 and a wheel axle 145, wherein the power output shaft of the first motor 141 is connected to the input shaft of the first reducer 142, the power output shaft of the first reducer 142 is connected to the connecting rod assembly 130, the input shaft of the first reducer 142 is used to drive the wheel axle 145 to rotate, the first reducer 142 and the first bearing seat 143 are arranged on the floating plate 120, the wire drawing wheel 144 is mounted on the wheel axle 145, and the wheel axle 145 is rotatably mounted on the first bearing seat 143.

[0030] When the wire drawing mechanism 100 is working, the power output shaft of the first motor 141 drives the input shaft of the first reducer 142 to rotate, and the power output shaft of the first reducer 142 drives the connecting rod assembly 130 to rotate. During the rotation of the connecting rod assembly 130, the floating plate 120 is pushed back and forth to slide back and forth along the sliding assembly 110, and the floating plate 120 drives the wire drawing wheel 144 to move back and forth; at the same time, the power input shaft of the first reducer 142 drives the wire drawing wheel 144 to rotate. In this way, when the wire drawing wheel 144 rotates to contact the product 300 for wire drawing, the wire drawing wheel 144 can move back and forth synchronously, so that snowflake patterns can be formed on the surface of the product 300. In this way, there is no need to move the product 300 back and forth manually, and there is no need to add other driving devices to drive the product 300 to move back and forth. In addition, the structure of the wire drawing mechanism 100 is relatively simple, the device volume is small, and the space occupied is small.

[0031] In one embodiment, the wire drawing mechanism 100 further includes a dust box 150. The wire drawing wheel 144 is rotatably mounted in the dust box 150, and the dust box 150 is provided with an opening 151 exposing the outer side wall of the wire drawing wheel 144. In this way, the outer side wall of the dust box 150 exposing the wire drawing wheel 144 can contact the product 300 and perform wire drawing on the surface of the product 300. In addition, the dust generated by the wire drawing on the surface of the product 300 will be sucked into the dust box 150 or fall into the dust box 150 due to its own gravity, which can prevent the dust from sticking to the product 300 and ensure the cleanliness of the product 300. Specifically, the opening 151 is opened at the top of the dust box 150, so that the product 300 passes through the top of the dust box 150, and the dust generated during the grinding process will naturally fall into the dust box 150 due to its own gravity. Of course, the opening 151 can also be opened at the side or bottom of the dust box 150.

[0032] Furthermore, the wire drawing mechanism 100 further includes a vacuum cleaner 160. The vacuum box 150 is provided with an air suction port, and the vacuum connector of the vacuum cleaner 160 is connected to the air suction port. In this way, the vacuum cleaner 160 provides power to suck the dust in the vacuum box 150 into the dust storage box of the vacuum cleaner 160.

[0033] Furthermore, the dust box 150 is provided with an openable cover 152. Thus, by opening the cover 152, the wire drawing wheel 144 can be loaded into or taken out of the dust box 150. Specifically, the bottom side of the cover 152 is rotatably arranged on the dust box 150 through a hinge, and the top side of the cover 152 is fastened to the dust box 150 through a buckle. All dust generated during operation enters the dust box 150 through the opening 151 and is sucked into the dust storage box of the vacuum cleaner 160. When the wire drawing wheel 144 needs to be replaced, only the buckle needs to be opened, and the cover 152 needs to be turned outward to replace the wire drawing wheel 144.

[0034] Furthermore, the wire drawing mechanism 100 further includes a seat plate 146 and a plurality of support rods 147 disposed between the seat plate 146 and the floating plate 120. The dust collecting box 150 and the first bearing seat 143 are mounted on the seat plate 146.

[0035] Specifically, a first pulley 171, a second pulley 172 and a driving belt 173 are provided between the output shaft of the first reducer 142 and the wheel shaft 145. The first pulley 171 is connected to the output shaft of the first reducer 142, the second pulley 172 is connected to the wheel shaft 145, and the driving belt 173 connects the first pulley 171 and the second pulley 172. Specifically, a tensioning wheel 174 is also provided between the input shaft of the first reducer 142 and the wheel shaft 145, and the tensioning wheel 174 is rotatably disposed on the seat plate 146, and is used to keep the driving belt 173 in a tensioned state. Optionally, the first pulley 171 and the second pulley 172 may also be sprockets, and driven by a driving chain.

[0036] Furthermore, the sliding assembly 110 includes a bottom plate 111 and a guide rail 112. The swimming plate 120 is connected with a slider 121 that is slidably matched with the guide rail 112, and the slider 121 is slidably arranged on the guide rail 112. Specifically, there may be more than two guide rails 112, and the more than two guide rails 112 are arranged in parallel and at intervals on the bottom plate 111. In this way, it can be ensured that the swimming plate 120 slides along the guide rail 112 more stably.

[0037] Furthermore, the connecting rod assembly 130 includes a crank 131 and a connecting rod 132, the power output shaft of the first reducer 142 is connected to one end of the crank 131, the other end of the crank 131 is rotatably connected to one end of the connecting rod 132, and the other end of the connecting rod 132 is rotatably connected to a fixed fulcrum on the base plate 111.

[0038] In one embodiment, please refer to Figures 6 to 9 A wire drawing device comprises the wire drawing mechanism 100 described in any of the above embodiments, and also comprises a feeding mechanism 200, wherein the feeding mechanism 200 is used to convey the product 300 whose surface is to be wire drawn to contact the outer wall of the wire drawing wheel 144.

[0039] Since the above-mentioned wire drawing device includes the above-mentioned wire drawing mechanism 100, its technical effect is brought by the wire drawing mechanism 100 and will not be described in detail.

[0040] In one embodiment, the feeding mechanism 200 includes a vacuum box 210, a first conveyor belt 220, a first active roller 231, a first driven roller 232 and a second motor 233. A strip-shaped opening 211 is provided on the bottom plate of the vacuum box 210 and is arranged along the conveying direction of the product 300. The vacuum box 210 is provided with a suction pipe 212 and is used to connect a suction device through the suction pipe 212. The second motor 233 drives the first active roller 231 to rotate, and the first conveyor belt 220 is arranged around the first active roller 231 and the first driven roller 232. The vacuum box 210 is located between the first active roller 231 and the first driven roller 232, and the bottom plate of the vacuum box 210 is in contact with the first conveyor belt 220. The first conveyor belt 220 is provided with a plurality of through holes 221 at intervals along the conveying direction of the product 300 . The through holes 221 are arranged corresponding to the strip-shaped openings 211 . The first conveyor belt 220 is arranged above the wire drawing wheel 144 of the wire drawing mechanism 100 .

[0041] The above-mentioned feeding mechanism 200, when feeding is working, the suction device is connected to the vacuum box 210 through the suction pipe 212, for example, the air inlet of the high-pressure fan is connected to the suction pipe 212, so that a negative pressure is formed at the strip opening 211 on the bottom plate of the vacuum box 210. Since the strip opening 211 is correspondingly connected to the through hole 221 on the first conveyor belt 220, the through hole 221 of the first conveyor belt 220 has an adsorption function, so that the product 300 to be subjected to surface wire drawing treatment can be adsorbed on the through hole 221 of the first conveyor belt 220, and transported by the first conveyor belt 220 to the top of the wire drawing wheel 144 of the wire drawing mechanism 100. When the wire drawing wheel 144 performs surface wire drawing treatment on the product 300, the dust generated falls directly downwards and will not stick to the surface of the product 300. This can improve the cleanliness of the wire drawing treatment and reduce the amount of cleaning on the surface of the product 300.

[0042] In one embodiment, the feeding mechanism 200 further includes a second bearing seat 234 and a second reducer 235. The first active roller 231 is provided with a first linkage shaft, and the first linkage shaft is rotatably mounted on the first bearing seat 143. The second motor 233 is connected to the first linkage shaft through the second reducer 235. In this way, when the second motor 233 is working, after the second reducer 235 stabilizes the speed, it drives the first linkage shaft to rotate, and the first linkage shaft drives the first active roller 231 to rotate. Optionally, the second motor 233 is directly connected to the first linkage shaft, so that there is no need to set the second reducer 235.

[0043] Specifically, the feeding mechanism 200 further includes a first support frame 236 . The first driven roller 232 is rotatably mounted on the first support frame 236 , and the vacuum box 210 is mounted on the first support frame 236 .

[0044] Further, the feeding mechanism 200 also includes a support seat 237 and a lifting and adjusting mechanism 238. The first support frame 236 is connected to the chassis 180 through the lifting and adjusting mechanism 238, and the second bearing seat 234 is installed on the support seat 237, and the support seat 237 is used to be arranged on the chassis 180. In this way, the support seat 237 and the lifting and adjusting mechanism 238 can make the first conveyor belt 220 and the chassis 180 have a gap, and the gap can be used to accommodate the wire drawing mechanism 100. In addition, the lifting and adjusting mechanism 238 can lift the first support frame 236, so as to adjust the gap between the first conveyor belt 220 and the wire drawing wheel 144, so as to achieve a better grinding effect of the wire drawing wheel 144 on the product 300. Among them, the lifting and adjusting mechanism 238 is specifically a universal ball foot, which has a simple structure and is more flexible and convenient to lift and lower. In addition, the lifting and adjusting mechanism 238 can also be a screw mechanism, a cylinder drive mechanism, etc., which will not be repeated.

[0045] Furthermore, the feeding mechanism 200 further includes a discharge guide plate 239. The discharge guide plate 239 is mounted on the first support frame 236, and the discharge guide plate 239 is spaced apart from the first conveyor belt 220, and the space between the discharge guide plate 239 and the first conveyor belt 220 can pass the product 300. In this way, after the wire drawing mechanism 100 performs wire drawing on the surface of the product 300, the product 300 continues to be conveyed forward by the first conveyor belt 220, and enters the space between the discharge guide plate 239 and the first conveyor belt 220, and is guided to the outside by the discharge guide plate 239. In addition, in order to facilitate the product 300 to enter the space between the discharge guide plate 239 and the first conveyor belt 220, one end of the discharge guide plate 239 close to the first active roller 231 is in an arc shape or an inclined plane shape inclined relative to the first conveyor belt 220.

[0046] For further information, please also refer to Figure 5 The feeding mechanism 200 further includes a feed guide plate 241, a second conveyor belt 242, a second active roller 243, a second driven roller 244, a transmission assembly and a second support frame 245. The second active roller 243 is provided with a second linkage shaft, and the first linkage shaft is connected to the second linkage shaft through the transmission assembly. The second conveyor belt 242 is arranged around the second active roller 243 and the second driven roller 244. The feed guide plate 241 is arranged on the second support frame 245 and is arranged corresponding to the output end of the second conveyor belt 242. The feed guide plate 241 is located below the first conveyor belt 220 and is arranged at a distance from the first conveyor belt 220. The distance between the feed guide plate 241 and the first conveyor belt 220 can pass the product 300. In this way, when the first active roller 231 rotates, the first linkage shaft of the first active roller 231 drives the second linkage shaft of the second active roller 243 to rotate, that is, the second active roller 243 rotates synchronously, and the second active roller 243 drives the second conveyor belt 242 to move, and the second conveyor belt 242 conveys the product 300 above it forward, and guides it to the first conveyor belt 220 through the feed guide plate 241.

[0047] Specifically, the transmission assembly includes a first gear 246 and a second gear 247. The first gear 246 and the second gear 247 are meshed with each other, the first gear 246 is mounted on the first linkage shaft, and the second gear 247 is mounted on the second linkage shaft.

[0048] In one embodiment, the feeding mechanism 200 further includes a first limiting plate 248 and a second limiting plate 249. The first limiting plate 248 and the second limiting plate 249 are arranged in parallel and spaced apart above the second conveyor belt 242, and the first limiting plate 248 and the second limiting plate 249 are used to respectively contact the two sides of the product 300. In this way, when the second conveyor belt 242 transports the product 300, the product 300 is limited by the first limiting plate 248 and the second limiting plate 249 on both sides thereof, ensuring that the product 300 enters the first conveyor belt 220 without deflection or tilt. Specifically, a plurality of products 300 are sequentially bonded to the tape, and the first limiting plate 248 and the second limiting plate 249 are respectively contacted on both sides of the tape, ensuring that the tape enters the first conveyor belt 220 in a preset direction. The adhesive tape is equivalent to a carrier, and is more easily adsorbed by the first conveyor belt 220 than a single product 300, so that each product 300 can be sequentially passed through the drawing wheel 144. When the product 300 on the adhesive tape passes through the drawing wheel 144, the drawing wheel 144 will perform surface drawing treatment.

[0049] In addition, the first limiting plate 248 is fixed to the second support frame 245 through the first positioning rod 251. The second limiting plate 249 is installed on the second positioning rod 252. The second support frame 245 is provided with a mounting plate 253. The mounting plate 253 is provided with a screw hole. The second positioning rod 252 is a screw corresponding to the screw hole. The second positioning rod 252 is installed in the screw hole. In this way, by adjusting the position of the second positioning rod 252 on the mounting plate 253, the distance between the second limiting plate 249 and the first limiting plate 248 can be adjusted to adapt to products 300 of different sizes.

[0050] In one embodiment, there are more than two suction pipes 212, and there is more than one partition in the vacuum box 210, and the partition divides the vacuum box 210 into more than two chambers. The suction pipe 212 is connected to the chamber. In this way, the vacuum box 210 is divided into more than two chambers, and each chamber has a corresponding suction pipe 212 connected to the suction device, which can ensure that the vacuum box 210 has a better adsorption effect and higher compatibility. Specifically, there are three suction pipes 212 and two partitions, which divide the vacuum box 210 into three chambers. In addition, in order to make the first conveyor belt 220 have a better adsorption effect on the product 300, the strip-shaped openings 211 on the bottom plate of the vacuum box 210 are specifically multiple, and accordingly, the through holes 221 on the first conveyor belt 220 are multiple rows, and each row of through holes 221 corresponds to a strip-shaped opening 211. When the first conveyor belt 220 rotates, each row of through holes 221 moves along the strip-shaped opening 211 and is connected with the strip-shaped opening 211, so that the first conveyor belt 220 can better adsorb the product 300.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
