Description

Technical Field

[0001] This utility model relates to the field of knotting machine technology, and in particular to a knotting mechanism for a konjac knotting machine. Background Technology

[0002] Konjac is a perennial herbaceous plant whose main component is glucomannan. It also contains various amino acids that the human body cannot synthesize, as well as minerals such as calcium, zinc, and copper. It is a high-quality dietary fiber that is low in fat, sugar, and calories and cholesterol-free. Konjac strips are strip-shaped food products made from konjac starch. To facilitate consumption (mainly for easy handling with chopsticks), the konjac strips are usually knotted. Currently, knotting konjac strips is mainly done manually, which is inefficient, labor-intensive, costly, and results in low daily output, making it difficult to scale up production. This prevents many konjac food manufacturers from fulfilling large orders for konjac strip knots. Therefore, there is an urgent need to design a mechanical knotting structure to solve the problems of low efficiency and low output caused by manual knotting, which is of great significance.

[0028] See Figures 1-2 A knotting mechanism for a konjac knotting machine is installed on a machine body 1. The machine body 1 is provided with a knotting structure 2, and a guide belt structure 3 is provided below the knotting structure 2.

[0030] The rotation drive structure 21 includes a rotation drive motor 211, which is mounted on a U-shaped mounting bracket 213, which is installed on the inner wall of the machine body 1. The motor shaft of the rotation drive motor 211 passes through the side wall of the U-shaped mounting bracket 213 and is fixed to a drive wheel 212, located on one side of the drive wheel 212. A sleeve 218 is fixed to the machine body 1, and a hollow rotating shaft 216 passes through the sleeve 218. Both ends of the sleeve 218 are rotatably connected to the rotating shaft 216 via bearings. The inner end of the rotating shaft 216 is located inside the machine body 1 and is fixed to a driven wheel 215. The drive wheel 212 and the driven wheel 215 are connected via a drive conveyor belt 214. When the rotation drive motor 211 operates, it drives the drive wheel 212 to rotate. The drive wheel 212 drives the driven wheel 215 to rotate via the drive conveyor belt 214, thereby driving the rotating shaft 216 to rotate. The outer end of the rotating shaft 216 is equipped with a spring clamp 217 for winding and gripping materials. The spring clamp 217 includes a left clamp body 2170 fixed on the left side of the front end of the rotating shaft 216, and a right clamp body 2171 rotatably connected to the right side of the front end of the rotating shaft 216. A clamp body spring 2172 is connected between the inner ends of the left clamp body 2170 and the right clamp body 2171. A triangular trigger block 2173 is protruding from the outer side of the rear end of the right clamp body 2171. The trigger block 2173 is located behind the rotation point of the right clamp body 2171.

[0031] The forward and backward displacement structure 22 includes a fixed frame 222 fixed inside the body 1. A displacement drive motor 221 is mounted on the fixed frame 222. One end of an eccentric component 223 is fixed to the motor shaft of the displacement drive motor 221. The other end of the eccentric component 223 is connected to a connecting rod 225 via a fisheye connector 224. Specifically, one end of the fisheye connector 224 is connected to the connecting rod 225, and the other end of the fisheye connector 224 is rotatably connected to the other end of the eccentric component 223. One end of the connecting rod 225 is connected to a guide rod 227 via a ball joint bearing 226. The ball joint bearing 226 is a ball-end ball joint bearing. The guide rod 227 passes through the interior of the rotating shaft 216. The outer end of the rotating shaft 216 has guide holes 2160 on both side walls. The outer side of the rotating shaft 216 is movably fitted with a sliding push rod 228 for driving the spring clamp 217 to open and close and pushing away the material wrapped around the spring clamp 217. The end of the guide rod 227 is fixedly connected to the sliding push rod 228. Specifically, the sliding push rod 428 includes a fixed sleeve 2280 movably sleeved outside the rotating shaft 216. The end of the guide rod 227 is fixedly connected to the fixed sleeve 2280 by bolts passing through the guide hole 2160. A side connecting rod 2281 is provided on one side of the fixed sleeve 2280. A front protrusion 2282 is provided on the inner side wall of the front end of the side connecting rod 2281. An elongated adjustment hole 2285 is provided at the rear end of the side connecting rod 2281. A rear protrusion 2284 is provided on the inner side wall of the inner end of the side connecting rod 2281. An inclined surface is provided on the inner front end of the rear protrusion 2284. The rear protrusion 2284 is fastened to the side connecting rod 2281 by bolts passing through the adjustment hole 2285. The installation position of the rear protrusion 2284 on the side connecting rod 2281 can be flexibly adjusted by adjusting the position of the bolts in the adjustment hole 2285. The end of the side connecting rod 2281 is vertically connected to a U-shaped push block 2283. The spring clamp 217 is located inside the opening of the push block 2283. The top and bottom surfaces of the opening of the push block 2283 are close to the top and bottom surfaces of the spring clamp 217, respectively, but do not contact them. The displacement drive motor 220 rotates forward or backward, causing the eccentric component 223 to rotate, which in turn moves the connecting rod 225. Under the action of the spherical bearing 226, the guide rod 227 moves forward or backward along the inside of the rotating shaft 216, and the front protrusion 2282 and the rear protrusion 2284 move forward or backward accordingly. In the initial state, the front protrusion 2282 is located on the front inclined surface of the trigger block 2173, applying force to the trigger block 2713. The clamp spring 2172 is in a compressed state, causing the spring clamp 217 to be in an open state. When the displacement drive motor 221 works, the front protrusion 2282 moves forward away from the trigger block 2173, allowing the spring clamp 217 to close under the action of the clamp spring 2172, and the push block 2283 moves forward accordingly.When push block 2283 moves forward, push block 2283 pushes away the material wrapped around spring clamp 217, causing it to disengage from spring clamp 217.

[0032] The clamping structure 23 includes a mounting member 234 fixed to the top of the outer end of the rotating shaft 216. A rotating member 236 is rotatably connected to the left side of the mounting member 234. A spring clamp 235 is fixed to the top of the rotating member 236, and the spring clamp 235 can rotate back and forth as the rotating member 236 rotates. The spring clamp 235 includes a left clamping body 2350 fixed to the top of the rotating member 236. A right clamping body 2351 is rotatably connected to the left clamping body 2350. A clamping spring 2352 is connected between the ends of the left clamping body 2350 and the right clamping body 2351. An extension 2353 is provided at the bottom of the front end of the right clamping body 2351. The spring clamp 235 is initially in a closed state. A limiting plate 2360 is provided at the rear end of the rotating component 236, and a stop block 2340 is provided at the top of the rear end of the mounting component 234. The limiting plate 2360 is located in front of the stop block 2340 and is used to restrict the rotating component 236 from rotating backward. The stop block 4340 has a threaded hole 2341, and a screw is threaded into the threaded hole 2341. A swing arm 237 is rotatably connected to the bottom of the rear end of the mounting component 234. A cylindrical contact handle 2370 is rotatably connected to the bottom of one end of the swing arm 237, and an arc plate 238 is rotatably connected to the other end of the swing arm 237. The other end of the arc plate 238 is rotatably connected to the side wall of the rotating component 236. A spring connector 232 is installed above the top of the rotating shaft 216 located between the sleeve 218 and the sliding push rod 228. A return spring 233 is connected between the spring connector 232 and the rotating component 236. A fixed bracket 231 is installed at the front end of the sleeve 218. The fixed bracket 231 includes a fixing member 2310 fixed on the sleeve 218 and a support rod 2311 connected to the right side of the fixing member 2310. The end of the support rod 2311 is rotatably connected to a one-way rotating block 230, which is used to open the spring belt clip 235. Specifically, the one-way rotating block is provided with a connecting hole 2301 and a through hole 2302. The end of the support rod 2311 is provided with a connecting hole 2313 and a limiting groove 2312 located below and behind the rotating connecting hole 2313. A pin is fixed in the connecting hole 2313, and the connecting hole 2301 is fitted onto the pin. A limiting pin is installed in the through hole 2302 and is accommodated in the limiting groove 2312. The one-way rotating block 430 rotates around the pin and slides in the limiting groove through the limiting pin, so that the one-way rotating block can only rotate upward and not downward. The one-way rotating block 230 is used to open the spring clip 235.

[0033] like Figure 10As shown, the guide belt structure 3 includes a mounting plate 31 installed at the bottom of the machine body 1. A guide belt drive motor 30 is mounted on the mounting plate 31. A guide belt shaft 33 is fixed to the motor shaft of the guide belt drive motor 30. A guide belt shaft fixing seat 32 is installed on the front wall of the machine body 1. The guide belt shaft passes through the guide belt shaft fixing seat 32, and an L-shaped pressure rod 35 is fixed to its outer end. A guide belt head 34, fixed to the guide belt shaft 33, is provided on the side of the pressure rod 35 near the machine body 1. The guide belt head 34 includes a fixing plate 340. A guide arc 341 is provided on the outer edge of the fixing plate 340. The guide arc 341 is concentric with the fixing plate 340, and the central axis of the fixing plate 340 coincides with the central axis of the guide belt shaft 33. The surface height of the guide arc 341 exhibits a smooth and monotonous increase from low to high. In the initial state, the guide arc of the guide head 34 is located at the bottom, and the part of the guide head without a guide arc is located at the top, so it will not obstruct the rotational movement of the spring belt clip 235.

[0034] like Figure 11 As shown, the steps of the knotting machine of this utility model for knotting materials are as follows: Step 1: The drive motor 211 is turned to operate, causing the driving wheel 212 to rotate, which in turn drives the driven wheel 215 to rotate. This causes the rotating shaft 216 to rotate from its initial position towards the material-picking position. Simultaneously, the spring clamp 235 rotates clockwise towards the material-picking position. The right clamp 2351 of the spring clamp 235 abuts downward against the one-way rotating block 230 on the fixed bracket 231. At this time, the one-way rotating block 230 cannot rotate downward due to its one-way rotation characteristic, thus applying upward pressure to the right clamp 2351. 2351 rotates to the left and approaches the clamp 2350, the clamp spring 2352 is compressed, the spring belt clamp 235 opens, and at this time it is in the material picking position. The clamping end 90 of the material falls into the opening of the spring belt clamp 235. Then the drive motor 211 rotates in the opposite direction, causing the rotating shaft 216 to rotate counterclockwise to the left. The spring belt clamp 235 disengages from the pressure of the one-way rotating block 230. Under the reverse force of the clamp spring 2352, the opening of the spring belt clamp 435 closes and clamps the material clamping end 90 in the picking position.

[0035] Step 2: Rotate the drive motor 211 to continue working, so that the spring belt clamp 435 returns to the initial position with the material in its grip. At this time, the spring belt clamp 235 pulls out a section of material from the material pick-up position. This section is the movable part 91 for tying the material.

[0036] Step 3: The drive motor 211 continues to operate, causing the spring clamp 235 to continue rotating counterclockwise one revolution while holding the material and returning to its initial position. This causes the material to wrap around the spring clamp 217 once, forming the winding part 92 for material knotting. During the counterclockwise rotation of the spring clamp 235, the material output from the feeding position is pushed forward manually or by an external mechanism, causing the movable part 91 to cross behind the winding part 92. It should be noted that the external mechanism can be a lever that moves back and forth, such as a lever fixed to the top of the slider of the linear slide. The lever moves back and forth under the action of the linear slide, perpendicular to the material conveying direction. During the counterclockwise rotation of the spring clamp 235, it encounters the one-way rotating block 230. Since the one-way rotating block 230 can rotate upward but not downward, it rotates upward under the upward force applied by the spring clamp 235, ensuring that the rotation of the spring clamp 235 is not obstructed by the one-way rotating block 230.

[0037] Step 4: The belt drive motor 30 of the belt guide structure 3 operates, causing the belt guide shaft 33 to rotate and drive the belt guide head 34 and pressure rod 35 to rotate synchronously. The contact handle 2370 of the knotting mechanism 2 contacts the lower end of the guide arc 341 of the belt guide head 54. As the belt guide head 34 rotates, the contact height between the contact handle 2370 and the surface of the guide arc 341 continuously increases, thereby pushing the contact handle 2370 forward, causing the swing arm 237 to rotate backward. The rotating part 236 drives the spring belt clamp 235 to rotate forward and downward, so that the material knotting movable part 91 enters the opening of the spring clamp 217.

[0038] Step 5: The displacement drive motor 221 operates, causing the eccentric component 223 to rotate, which in turn drives the connecting rod 225 to move. Under the action of the spherical bearing 226, the guide rod 227 moves forward along the hollow structure inside the rotating shaft 216, thereby driving the sliding push rod 228 to move forward. The protrusion of the sliding push rod 228 moves forward accordingly, relieving the pressure of the front protrusion 2282 on the trigger block 2173. The spring clamp 217 closes under the elastic force of the clamp body spring 2172 and clamps the movable part 91 of the material. At the same time, the push block 2283 of the sliding push rod 228 pushes the winding part 92 of the material forward, causing the winding part 92 to move forward and disengage from the spring clamp 217, thus completing the knotting of the material. Subsequently, the knotted tail 93 of the material is cut manually or by an external cutting mechanism. The external cutting mechanism is a pneumatic scissor that moves back and forth, such as a pneumatic scissor set on the slider of a linear slide table. The sliding push rod 228 continues to move forward until the inclined surface of the rear protrusion 2284 contacts and presses against the rear inclined surface of the trigger block 2173 of the spring clamp 217, applying force to the rear end of the right clamp body 2171, causing the right clamp body to rotate around the rotation point. The spring clamp opens, releasing the clamping of the konjac knot movable part 91. Subsequently, the displacement drive motor 221 works in the opposite direction, causing the eccentric part 223 to rotate in the opposite direction, causing the guide rod 227 to move backward along the hollow structure inside the rotating shaft 416, thereby returning the sliding push rod 228 to its initial position. The pressure rod 35 of the guide belt structure 3 rotates to the spring belt clamp 235, and during the continued rotation, it applies pressure to the right side of the extension 2353 at the bottom of the right clamp body 2351 of the spring belt clamp 235, causing the spring belt clamp 235 to open and release the clamping of the material knotting clamping end 90.

[0039] Step six: After the knotted material falls into the receiving device, the belt drive motor starts working, causing the belt head and pressure bar to return to their initial state.

[0040] In the above knotting step, the material is knotted by the combination of knotting structure and guide belt structure. Compared with simply relying on manual knotting, the knotting efficiency is high and the output can be increased.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
