Description

Technical Field

[0001] The present invention relates to the technical field of agricultural and sideline product packaging, in particular to a post-processing packaging production line for agricultural and sideline products. Background Art

[0002] When selling garlic, it is usually placed in a mesh strip bag. When packing, workers need to unfold the mesh bag and put it on a standing hollow plastic tube. Then, they need to take out six garlic heads from a pile of garlic of similar size and put them into the hollow tube. Then, they hold the outer end of the mesh bag, take the mesh bag out of the hollow plastic tube, and tie a knot at the opening of the outer end of the mesh bag to complete the bagging of a group of garlic.

[0003] Patent document CN202010265816.2 discloses a quantitative packaging device for fixed-point or temporary sales, including a driving cavity at the bottom of the main body and a rotating cavity at the top of the main body, which is in a semi-open state; the control electrical box is installed on the top of the main body, and the control electrical box is connected to the external power supply line; the storage funnel is installed on the top end face of the main body; the mesh bag inside each storage tube is filled with six garlic cloves to ensure the equality of the amount of garlic inside the storage tube.

[0004] However, during actual use, the inventors found that the garlic packed in the strip mesh bag had poor stability and was easily rotated and turned by external forces, resulting in inconsistent orientation of the garlic stems, which affected the aesthetics of the garlic packaging and was not conducive to the sale of the garlic. In addition, during transportation, the garlic array in the mesh bag was easily bent by external forces, resulting in the mesh bag being broken or the garlic being damaged. Summary of the Invention

[0005] The object of the present invention is to address the deficiencies of the prior art and provide a post-packaging production line for processing agricultural and sideline products. The production line can automatically complete the unloading, arrangement and stringing of garlic bulbs through the cooperation of a supporting mechanism and a threading mechanism. A plurality of garlic bulbs are stringed and limited by a hollow webbing to ensure that the garlic stalks are oriented in the same direction, thereby improving the neatness and aesthetics of garlic packaging. The garlic queue is not easily bent, thus avoiding the rupture of the net bag or the damage of the garlic bulbs, thereby improving the packaging effect of the garlic bulbs. The technical problems of poor stability of garlic in the existing strip net bag, inconsistent orientation of the garlic stalks, and susceptibility of the garlic queue to bending due to external force during transportation, which may lead to the rupture of the net bag or damage of the garlic, are solved.

[0026] Beneficial effects of the present invention:

[0027] (1) The present invention cooperates with the supporting mechanism and the threading mechanism. On the one hand, before the garlic is packed in the net bag, the hollow webbing is used to limit the position of the multiple garlic heads in series, thereby improving the stability between the garlic heads, ensuring that the garlic stems are oriented in the same direction, improving the neatness and beauty of the garlic packaging, and better meeting market demand. In addition, the garlic head queue with limit position in series is not easy to bend, thus avoiding the net bag from breaking or the garlic heads from being damaged. On the other hand, the garlic can be automatically cut, arranged and connected in series, with good structural linkage, thereby improving the packaging effect of the garlic heads, and enabling batch production of packaged garlic heads, thereby increasing the efficiency of the enterprise.

[0028] (2) The present invention cooperates with the straightening component and the clamping component. On the one hand, the garlic stems on the clamping plate can be automatically straightened downward, ensuring the smoothness of the garlic perforation and improving the perforation effect of the garlic. On the other hand, while straightening the garlic stems downward, there is also a corresponding pulling effect on the garlic, so that the garlic is tightly pressed in the semicircular clamping hole of the clamping plate, preventing the garlic from shaking during the perforation process, and improving the stability of the garlic perforation.

[0029] (3) The powder injection component and the gathering component provided in the present invention cooperate with each other. On the one hand, the moisture-proof agent powder can be automatically injected into the hollow ribbon of the connected garlic heads, which not only increases the storage time of the garlic heads and ensures the sales quality of the garlic heads, but also the moisture-proof agent powder is filled in the hollow ribbon, which can improve the overall hardness of the hollow ribbon and further prevent the connected garlic heads from bending. On the other hand, the connected garlic heads can be gathered together so that the connected garlic heads are in close contact with each other, thereby improving the stability of the garlic heads.

[0051] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0052] Example 1

[0053] like Figure 1-20 As shown, a post-packaging production line for agricultural and sideline products processing includes a carrying mechanism 2, a feeding mechanism 3, a threading mechanism 4 and a filling mechanism 5 arranged on a conveyor frame 1;

[0054] The threading mechanism 4 includes a punching assembly 41 arranged on the conveying frame 1 and used to punch holes in the middle of the garlic on the carrying mechanism 2 from top to bottom, a waste cleaning assembly 42 arranged on the conveying frame 1, a lead assembly 43 arranged on the punching assembly 41 and used to pull the hollow ribbon from bottom to top and insert it into the middle of the garlic, and a slitting assembly 44 arranged on the conveying frame 1 and used to cut the hollow ribbon.

[0055] It is worth mentioning that after the pre-processing of screening, the specifications of the garlic are basically the same, and the garlic stems are shed and strung downward.

[0056] It should be noted that after the garlic bulbs are connected and tied together, the connected garlic bulbs are transferred to the next existing process for mesh bag packaging.

[0057] In this embodiment, by cooperating with the supporting mechanism 2 and the threading mechanism 4, on the one hand, before the garlic is packed in the net bag, the hollow webbing is used to limit the position of multiple garlic heads in series, thereby improving the stability between the garlic heads, ensuring that the garlic stems are oriented in the same direction, improving the neatness and aesthetics of the garlic packaging, and better meeting market demand. In addition, the garlic head queue with limit in series is not easy to bend, thus avoiding the rupture of the net bag or the damage of the garlic heads. On the other hand, the unloading, arrangement and connection of the garlic heads can be completed automatically, the structural linkage is good, the packaging effect of the garlic heads is improved, and the packaged garlic heads can be mass-produced to increase the efficiency of the enterprise.

[0058] In detail, the conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the unloading mechanism 3 and then stops. The blanking component 32 releases individual garlic heads onto the clamping component 21 in sequence under the control of the material control component 33. The straightening component 22 straightens the stalks of the garlic heads downwards. Then, the conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the threading mechanism 4 and then stops. The perforating component 41 punches holes in the middle of the garlic heads on the clamping component 21 from top to bottom in sequence. The waste cleaning component 42 collects the waste generated by the punching. The lead component 43 pulls the hollow webbing from bottom to top and inserts it into the middle of the garlic heads in sequence. The slitting component 44 cuts the hollow webbing. The first clamp 433 and the second clamp 434 respectively clamp the lower end and the upper end of the cut hollow webbing. Then, the conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the filling mechanism 5 and then stops. During operation, the clamping assembly 21 opens and releases the connected garlic heads, and the gathering assembly 54 gathers the connected garlic heads to the middle position of the hollow ribbon so that the connected garlic heads are in close contact with each other. Then, the first clamping strip 433 releases the lower end of the hollow ribbon, and the heat-sealing assembly 55 retracts the lower end of the hollow ribbon upward and performs heat-sealing and splicing. Then, the second clamping strip 434 opens the upper end of the hollow ribbon, and the powder injection tube 523 descends into the upper end of the hollow ribbon. The air blowing assembly 53 blows air into the hollow ribbon to fill and expand the hollow ribbon. The powder injection tube 523 then injects a certain amount of moisture-proof agent powder into the hollow ribbon. Then, the second clamping strip 434 releases the upper end of the hollow ribbon, and the heat-sealing assembly 55 retracts the upper end of the hollow ribbon downward and performs heat-sealing and splicing, thereby completing the string splicing work of the garlic heads, and then transferring to the next existing process for mesh bag packaging.

[0059] Further, if Figure 2-9 As shown, the carrying mechanism 2 includes a clamping assembly 21 provided on the conveyor belt 11 of the conveyor frame 1 and used to support multiple layers of multiple groups of garlic bulbs, and a straightening assembly 22 provided on the clamping assembly 21 and used to straighten the garlic bulb stems;

[0060] The clamping assembly 21 includes a frame 211 arranged on the conveyor belt 11, several groups of L-shaped support plates 212 that pass through and are slidably arranged on the inner wall of the frame 211, a clamping plate 213 arranged at the end of the L-shaped support plate 212, several groups of semicircular clamping holes 214 opened on the side of the clamping plate 213, a first elastic member 215 arranged between the L-shaped support plate 212 and the outer wall of the frame 211, an extension rod 216 arranged on the side of the L-shaped support plate 212, a first hydraulic member 217 arranged on the outer wall of the frame 211, and a push rod 218 arranged at the output end of the first hydraulic member 217 and used to drive the extension rod 216 to open the clamping plate 213.

[0061] It should be noted that the semicircular clamping holes 214 on the sides of the two clamping plates 213 are used to clamp the garlic with the stem facing downward. The upper edge of the semicircular clamping holes 214 is provided with a sloped rubber pad. On the one hand, it prevents the garlic from being crushed on the semicircular clamping holes 214. On the other hand, it prevents the garlic from rotating during the perforation process, increases the friction between the semicircular clamping holes 214 and the garlic, and ensures the perforation effect of the garlic.

[0062] In this embodiment, the clamping assembly 21 is provided to automatically clamp and support the garlic in multiple layers to ensure the serial connection of the garlic.

[0063] In detail, the conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the unloading mechanism 3 and then stops. The first hydraulic component 217 drives the push rod 218 to move synchronously to both sides with the L-shaped support plate 212 through the extension rod 216, thereby opening the two clamping plates 213. Then, the blanking barrel 322 of the blanking assembly 32 descends to the bottom of the frame 211 between the two opened clamping plates 213. The first hydraulic component 217 drives the push rod 218 to reset, so that the clamping plates 213 are synchronously pressed against both sides of the outer wall of the blanking barrel 322. Then, the blanking barrel 322 intermittently rises a specified distance. After the lower end of the blanking barrel 322 detaches from a group of clamps 213, the two clamps 213 of the group are reset to contact under the drive of the first elastic member 215, and the blanking barrel 322 releases a single garlic into the semicircular clamping hole 214 of the two clamps 213 of the group. Thus, as the blanking barrel 322 intermittently rises, the garlic is released from the semicircular clamping holes 214 of multiple groups of clamps 213 from bottom to top in turn, achieving the effect of automatically clamping and supporting the garlic in multiple layers.

[0064] Further, if Figure 3-6As shown, the straightening assembly 22 includes a hanging plate 221 arranged on the lower surface of the clamping plate 213, an inclined straightening plate 222 hingedly arranged at the bottom of the hanging plate 221, a second hydraulic component 223 arranged on the lower surface of the clamping plate 213 and used to drive the inclined straightening plate 222, and a semicircular straightening hole opened on the side of the inclined straightening plate 222 and adapted to the garlic stem.

[0065] In this embodiment, by cooperating with the straightening component 22 and the clamping component 21, on the one hand, the garlic stems on the clamping plate 213 can be automatically straightened downward, ensuring the smoothness of the garlic perforation and improving the perforation effect of the garlic; on the other hand, while straightening the garlic stems downward, there is also a corresponding pulling effect on the garlic, so that the garlic is tightly pressed in the semicircular clamping hole 214 of the clamping plate 213, preventing the garlic from shaking during the perforation process, and improving the stability of the garlic perforation.

[0066] In detail, the second hydraulic component 223 drives the inclined stroking plate 222 to rotate downward, so that the sides of the two inclined stroking plates 222 approach each other, so that the semicircular stroking holes of the inclined stroking plates 222 straighten the garlic stems downward.

[0067] Further, if Figure 2-9 As shown, the feeding mechanism 3 includes a first lifting assembly 31 provided on the conveying frame 1, a feeding assembly 32 provided on the first lifting assembly 31 and containing a plurality of groups of garlic bulbs, and a material control assembly 33 provided on the feeding assembly 32 and used to control the falling of a single garlic bulb.

[0068] The first lifting assembly 31 includes a bracket 311 provided on the conveyor frame 1, two sets of first screw rods 312 vertically rotatably provided on the bracket 311, and a first stepper motor 313 provided on the bracket 311 and used to drive the first screw rods 312;

[0069] The blanking assembly 32 includes a first lifting plate 321 threadedly mounted on the first screw rod 312 and a plurality of blanking barrels 322 arranged side by side on the first lifting plate 321 , with the garlic stalks in the blanking barrels 322 facing downward.

[0070] It should be noted that after the blanking barrel 322 descends to the bottom of the frame 211, it intermittently rises a specified distance. After each time the blanking barrel 322 rises a specified distance, the distance from the lower end of the blanking barrel 322 to the clamping plate 213 is equal to the height of one garlic head, ensuring that the penultimate garlic head falls into the semicircular clamping hole 214 of the clamping plate 213, and the penultimate garlic head does not completely break away from the lower end of the blanking barrel 322, so that the oblique grasping plate 331 of the material control component 33 can grasp the penultimate garlic head, thereby achieving the purpose of the blanking barrel 322 releasing a single garlic head each time to fall into the semicircular clamping hole 214 of the clamping plate 213.

[0071] In this embodiment, by cooperating with the blanking assembly 32 and the clamping assembly 21, individual garlic bulbs can be released sequentially from bottom to top onto the multi-layer clamping plates 213, thereby achieving the effect of automatic garlic blanking.

[0072] In detail, the conveyor belt 11 carries the carrying mechanism 2 to the position just below the unloading mechanism 3 and then stops. After the splints 213 of the carrying mechanism 2 are opened to both sides, the first stepping motor 313 of the first lifting assembly 31 drives the first screw rod 312 to drive the first lifting plate 321 to descend, so that the lower end of the blanking barrel 322 drops to the bottom of the frame 211, and then the splint 213 is against the two sides of the outer wall of the blanking barrel 322, and the first lifting assembly 31 drives the blanking barrel 322 to rise a specified distance. After the lower end of the blanking barrel 322 disengages from a group of splints 213, the splints 213 are reset and contacted, and the material control assembly 33 controls the blanking barrel 322 to release a garlic and fall into the semicircular clamping hole 214 of the two splints 213 of the group, and then, the first lifting assembly 31 drives the blanking barrel 322 to rise a specified distance again, thereby releasing a single garlic onto the multiple layers of splints 213 in turn.

[0073] Further, if Figure 7-9 As shown, the material control assembly 33 includes two groups of oblique grab plates 331 symmetrically hingedly arranged at the lower end of the blanking barrel 322, two groups of shafts 332 arranged at the lower end of the blanking barrel 322 and used to drive the oblique grab plates 331 to open and close, a first gear 333 arranged at the end of the shaft 332, a third hydraulic component 334 arranged at the bottom of the first lifting plate 321, and two groups of racks 335 arranged at the output end of the third hydraulic component 334 and used to drive the first gear 333 respectively.

[0074] In this embodiment, the material control assembly 33 is provided to control the blanking assembly 32 to release a single garlic bulb each time.

[0075] In detail, after the first lifting assembly 31 drives the blanking barrel 322 to rise a specified distance, the third hydraulic component 334 drives the rack 335 to descend, so that the rack 335 drives the oblique grasping plate 331 to open to both sides through the first gear 333 and the shaft 332, so that the penultimate garlic bulb falls into the semicircular clamping hole 214 of the clamping plate 213. Then, the third hydraulic component 334 drives the rack 335 to rise and reset, so that the oblique grasping plate 331 clamps and grasps the penultimate garlic bulb.

[0076] Further, if Figure 10-14 As shown, the threading mechanism 4 further includes a second lifting assembly 45 provided on the conveying frame 1 , and the punching assembly 41 is provided on the second lifting assembly 45 ;

[0077] The perforating assembly 41 includes a second lifting plate 411 disposed on the second lifting assembly 45, a plurality of perforated tubes 412 that penetrate and rotate on the second lifting plate 411, second gears 413 disposed on the outer walls of the perforated tubes 412 and meshing with each other, a third gear 414 disposed on the second lifting plate 411 and used to drive the second gears 413, a second stepping motor 415 disposed at the bottom of the second lifting plate 411 and used to drive the third gear 414, and a negative pressure machine 416 disposed on the second lifting plate 411 and connected to the upper ends of the perforated tubes 412 through hoses.

[0078] The waste cleaning assembly 42 includes several groups of leakage holes 421 opened on the bottom of the frame 211 and the conveyor belt 11 for the perforated tube 412 to pass through, a fourth hydraulic component 422 arranged at the inner end of the perforated tube 412, a push plate 423 arranged at the output end of the fourth hydraulic component 422 and used to push the waste in the perforated tube 412 out, a waste collection box 424 arranged on the conveyor frame 1, and a blower 425 arranged on the side wall of the waste collection box 424 and used to blow the waste to one side.

[0079] It should be noted that the second lifting assembly 45 has the same structure as the first lifting assembly 31 , and the second lifting plate 411 is threadedly disposed on the first screw rod 312 of the second lifting assembly 45 .

[0080] In this embodiment, by cooperating with the provided perforating assembly 41 and the waste cleaning assembly 42, multiple layers of garlic can be perforated sequentially from top to bottom, and the waste generated by the perforation can be cleaned.

[0081] In detail, the conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the threading mechanism 4 and then stops, the second lifting assembly 45 drives the second lifting plate 411 to descend, and the second lifting plate 411 descends with the perforated tube 412. At the same time, the second stepper motor 415 drives the perforated tube 412 to rotate through the third gear 414 and the second gear 413, thereby punching the middle position of the garlic. At the same time, the negative pressure machine 416 forms a negative pressure in the perforated tube 412, so that the perforated tube 412 is punched. The generated waste is sucked into the perforated tube 412. After the multiple layers of garlic are punched, the lower end of the perforated tube 412 continues to descend into the waste collection box 424 through the leakage hole 421. Then, the fourth hydraulic component 422 drives the push plate 423 to push the waste in the perforated tube 412 into the waste collection box 424. At the same time, the blower 425 blows the waste to one side of the waste collection box 424 to prevent the waste from accumulating in the guide hole of the waste collection box 424, so as to facilitate the operation of the lead assembly 43.

[0082] Further, if Figure 4-5 and Figure 10-14As shown, the cutting assembly 44 includes several groups of fifth hydraulic components 441 symmetrically arranged on the inner side wall of the waste collection box 424, a mounting plate 442 arranged at the output end of the fifth hydraulic component 441, a clamping block 444 arranged on the mounting plate 442 via an elastic telescopic member 443, and a cutter 445 arranged on the mounting plate 442, wherein the clamping block 444 is in contact with the inner bottom of the waste collection box 424;

[0083] The lead assembly 43 includes several groups of rollers 431 with hollow webbings arranged on the conveying frame 1, a guide hole opened at the bottom of the waste collection box 424 for the hollow webbing to pass through, a suction cup 432 arranged at the bottom of the push plate 423 and connected to the negative pressure machine 416 through a hose, two groups of first clamps 433 arranged on the side wall of the frame 211 through the sixth hydraulic component and used to clamp the lower end of the hollow webbing, two groups of second clamps 434 arranged on the side wall of the frame 211 through the seventh hydraulic component and used to clamp the upper end of the hollow webbing, and several groups of vacuum suction holes 435 arranged on the second clamps 434 and used to open the upper end of the hollow webbing. An existing vacuum generator is set on the side wall of the frame 211, and the vacuum generator is connected to the vacuum suction hole 435 through a hose.

[0084] In this embodiment, the provided lead assembly 43 and the slitting assembly 44 cooperate to automatically pull the hollow ribbon from bottom to top through the middle position of the multi-layer garlic.

[0085] In detail, after the push plate 423 pushes out the waste in the perforated tube 412, the fifth hydraulic component 441 of the slitting assembly 44 drives the mounting plate 442 to move to both sides, so that the two cutters 445 are separated first. At the same time, the push plate 423 continues to descend above the two clamping blocks 444, and the vacuum suction hole 435 at the bottom of the push plate 423 sucks the upper end of the hollow webbing. Then, the two clamping blocks 444 are opened, the perforated tube 412 rises, and the hollow webbing of a specified length is pulled from the reel 431. The fifth hydraulic component 441 drives the mounting plate 442 to reset, so that the two clamping blocks 444 first clamp the hollow webbing, and the two cutters 445 cut the hollow webbing again. Then, the first clamping strip 433 clamps the lower end of the hollow webbing, and the second clamping strip 434 clamps the upper end of the hollow webbing. Finally, the vacuum suction hole 435 releases the hollow webbing, and the push plate 423 rises and resets for next use.

[0086] Further, if Figure 3-4 and Figure 15-20As shown, the filling mechanism 5 is used to fill the interior of the hollow ribbon at the middle of the garlic heads with moisture-proof agent powder, and includes a third lifting assembly 51 provided on the conveying frame 1, a powder injection assembly 52 provided on the third lifting assembly 51, a blast assembly 53 provided on the powder injection assembly 52 and used to expand the hollow ribbon, a gathering assembly 54 provided on the third lifting assembly 51 and used to drive several groups of garlic heads on the same hollow ribbon to move closer together, and a heat sealing assembly 55 provided on the gathering assembly 54 and used to seal the hollow ribbon.

[0087] The powder injection assembly 52 includes a third lifting plate 521 provided on the third lifting assembly 51, a powder storage box 522 provided on the third lifting plate 521, and a powder injection pipe 523 provided at the bottom of the powder storage box 522;

[0088] The air blowing assembly 53 includes a vent pipe 531 that is sleeved on the outside of the powder injection pipe 523 and a blower 532 that is installed on the third lifting plate 521 and connected to the vent pipe 531 through a hose.

[0089] The folding assembly 54 includes a hanger 541 fixedly mounted on the bracket 311 of the third lifting assembly 51, a second screw rod 542 vertically mounted on the hanger 541, two sets of lifting blocks 543 threadedly mounted on the second screw rod 542, an eighth hydraulic component 544 mounted on the lifting blocks 543, a mounting bracket 545 mounted on the output end of the eighth hydraulic component 544, two sets of heat-sealing plates 546 symmetrically slidably mounted on the mounting bracket 545, and a ninth hydraulic component 547 mounted on the mounting bracket 545 and used to drive the heat-sealing plates 546. The second screw rod 542 is driven by a third stepping motor.

[0090] The heat sealing assembly 55 includes an extension plate 551 arranged on the heat sealing plate 546, a retraction roller 552 slidably arranged on the extension plate 551 through a sliding hole, and a second elastic member 553 arranged inside the sliding hole and used to drive the retraction roller 552 to reset. The retraction roller 552 is driven by a fourth stepper motor.

[0091] It should be noted that the third lifting assembly 51 has the same structure as the first lifting assembly 31 , and the third lifting plate 521 is threadedly disposed on the first screw rod 312 of the third lifting assembly 51 .

[0092] In this embodiment, the powder injection component 52 and the gathering component 54 cooperate to automatically inject moisture-proof powder into the hollow ribbon of the connected garlic heads, which not only increases the storage time of the garlic heads and ensures the sales quality of the garlic heads, but also fills the hollow ribbon with moisture-proof powder, which can increase the overall hardness of the hollow ribbon and further prevent the series of garlic heads from bending; on the other hand, the series of garlic heads can be gathered together so that the series of garlic heads are in close contact with each other, thereby improving the stability of the garlic heads.

[0093] In detail, the conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the threading mechanism 4 and then stops. The eighth hydraulic component 544 drives the mounting frame 545 to move, so that the heat sealing plates 546 are respectively inserted on both sides of the upper end and the lower end of the hollow webbing. Then, the clamping plates 213 of the clamping assembly 21 open to both sides and disengage from the garlic. The third stepper motor drives the heat sealing plates 546 to retract the garlic through the second screw rod 542, so that the garlic gathers to the middle position of the hollow webbing. Then, the first clamping strip 433 releases the lower end of the hollow webbing. The ninth hydraulic component 547 drives the heat sealing plate 546 to clamp and seal the hollow webbing. At the same time, the retracting roller 552 rotates, so that the retracting roller 552 retracts the lower end of the hollow webbing upward to the heat sealing plate 546, so that the heat sealing plate 546 seals the lower end of the hollow webbing. Afterwards, the vacuum suction hole 435 of the second clamping strip 434 opens the upper end of the hollow webbing, and the third lifting assembly 51 drives the powder injection assembly 52 to descend, so that the powder injection tube 523 descends to the upper end of the hollow webbing, and the blower 532 inflates the hollow webbing through the vent pipe 531, so that the hollow webbing is filled and expanded. Then, the powder injection tube 523 injects a certain amount of moisture-proof agent powder into the filled hollow webbing, and the powder injection tube 523 rises and resets, and the second clamping strip 434 releases the upper end of the hollow webbing, and the retracting roller 552 rotates to retract the upper end of the hollow webbing downward to the heat sealing plate 546, so that the heat sealing plate 546 seals the upper end of the hollow webbing. Finally, the ninth hydraulic component 547 drives the heat sealing plate 546 to reset, so that the heat sealing plate 546 is transferred with the connected garlic, and the empty carrying mechanism 2 is recycled.

[0094] Example 2

[0095] like Figure 2 and Figure 15 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0096] Further, if Figure 2 and Figure 15As shown, it also includes a discharge mechanism 6 arranged on the hanger 541 and used to remove the bunches of garlic from the collection component 54, the discharge mechanism 6 includes rake teeth arranged on the hanger 541, and the heat sealing component 55 passes through the middle of the rake teeth.

[0097] It is worth mentioning that when the heat-sealing plate 546 is transferring the garlic bulbs in series, the garlic bulbs in series are separated from the heat-sealing plate 546 when passing through the rake teeth of the unloading mechanism 6 and are output to the next process for mesh bag packaging.

[0098] Working process:

[0099] The conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the unloading mechanism 3 and then stops. The unloading component 32 releases individual garlic bulbs onto the clamping component 21 in sequence under the control of the material control component 33. The straightening component 22 straightens the stalks of the garlic bulbs downwards. Then, the conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the threading mechanism 4 and then stops. The punching component 41 punches holes in the middle of the garlic bulbs on the clamping component 21 from top to bottom in sequence. The waste cleaning component 42 collects the waste generated by the punching. The lead component 43 pulls the hollow webbing from bottom to top and inserts it into the middle of the garlic bulbs in sequence. The slitting component 44 cuts the hollow webbing. The first clamping strip 433 and the second clamping strip 434 respectively clamp the lower end and the upper end of the cut hollow webbing. Then, the conveyor belt 11 carries the carrying mechanism 2 forward to the position just below the filling mechanism 5 and then stops. The clamping assembly 21 opens to release the connected garlic heads, and the gathering assembly 54 gathers the connected garlic heads to the middle position of the hollow ribbon so that the connected garlic heads are in close contact with each other. Then, the first clamping strip 433 releases the lower end of the hollow ribbon, and the heat-sealing assembly 55 retracts the lower end of the hollow ribbon upward and performs heat-sealing and tying. Then, the second clamping strip 434 opens the upper end of the hollow ribbon, and the powder injection tube 523 descends into the upper end of the hollow ribbon. The air blowing assembly 53 blows air into the hollow ribbon to fill and expand the hollow ribbon. The powder injection tube 523 then injects a certain amount of moisture-proof agent powder into the hollow ribbon. Then, the second clamping strip 434 releases the upper end of the hollow ribbon, and the heat-sealing assembly 55 retracts the upper end of the hollow ribbon downward and performs heat-sealing and tying, thereby completing the stringing and tying of the garlic heads, and then transferring to the next existing process for mesh bag packaging.
