Detailed Description

In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

Example 1:

referring to fig. 1 and 2, the present embodiment provides a packing and cutting mechanism, including: the clamp plate assembly, the clamp plate driving assembly and the cutter assembly.

Specifically, the clamping plate assembly comprises a pair of symmetrically arranged clamping plates 31, and symmetrically distributed grooves 32 are respectively formed on the opposite facing end surfaces of the pair of clamping plates 31; and a clamp driving assembly including a clamp driving structure connected to the pair of clamps 31 in a one-to-one correspondence to drive the pair of clamps 31 to move toward and away from each other. The cutter assembly comprises a cutter blade 33 embedded in the groove 32 of one clamping plate 31 of the pair of clamping plates 31, a pair of connecting columns 38 fixedly connected with the two ends of the cutter blade 33 in the width direction respectively, and a cutter blade driving structure which is matched and connected with the connecting columns 38 simultaneously and is suitable for driving the cutter blade 33 to reciprocate relative to the other clamping plate 31.

It should be noted that the width of the groove 32 in this embodiment is greater than the width of the blade 33, so that the width of the groove 32 does not limit the moving track of the blade 33 during the process of cutting the packaging bag by moving the blade 33 in the groove 32, that is, the groove 32 forms a movable knife slot of the blade 33; with this structure, the blade 33 can be completely inserted into the groove 32 during the packing operation of the packing bag by the clamp plate 31, and the situation that the blade 33 contacts the packing bag before the packing bag is not packed to damage the packing bag can not occur.

In detail, the clamp driving structure includes a movable plate 35 connected to the clamp plate 31 by a pair of links 34, and a first driving cylinder 36 connected to the movable plate 35; the first driving cylinder 36 is fixed to a cylinder fixing plate 37. In view of improving the accuracy of the tracks of the pair of clamping plates 31 during the movement of the two clamping plates towards and away from each other, a guide post 42 is further provided between the cylinder fixing plates 37 corresponding to the pair of clamping plates 31; the movable plate 35 is movably sleeved and matched with the guide post 42.

In addition, the blade driving structure of the present embodiment includes a push plate 39 connected to the pair of connecting posts 38 in a mating manner, and a pneumatic spring 40 connected to the push plate 39; in which a pneumatic spring 40 is fixed to the cylinder fixing plate 37.

In summary, the specific use principle of the packing and cutting mechanism of the embodiment is as follows:

before the packing and cutting mechanism does not perform an operation for the packing bag, the pair of clamp plates 31 are in a separated state, a section through which the packing bag passes is formed between the pair of clamp plates 31, and the blade 33 is completely built in the groove 32 of one of the clamp plates 31.

When the packing bag is sealed, the pair of clamping plates 31 move oppositely under the action of the first driving cylinders 36 corresponding to the clamping plates 31, so that the pair of clamping plates 31 clamp and seal the packing bag; after the packing of the packing bag is completed, the blade 33 cuts the packing bag by the pneumatic spring 40 to form a zigzag groove on the packing bag.

After the packing and cutting operations for the packing bag are completed, the blade 33 is returned to the original position under the action of the pneumatic spring 40, and then the first driving cylinder 36 is used for realizing the separation movement of the pair of clamping plates 31, so that the packing bag can be circulated continuously to facilitate the packing and cutting mechanism to carry out a new round of packing and cutting operations for the next to-be-operated part of the packing bag.

Example 2:

referring to fig. 1 to 10, based on the packing and cutting mechanism of embodiment 1, the present embodiment provides a workpiece conveying and packaging device, including: a workpiece conveying mechanism, a discharge pipe 9 connected with the workpiece conveying mechanism, a packaging mechanism matched with the discharge pipe 9, and the packing and cutting mechanism of the embodiment 1.

Specifically, the bag feeding assembly includes a winding roller 102 that winds a bag material 101 (the bag material 101 referred to in this embodiment refers to a raw material for forming a packaging bag), and a plurality of guide rollers 103 that guide out the bag material 101; that is, the packaging bag material is wound around the winding roller 102, passes through the plurality of guide rollers 103, and is introduced into the bag winding structure.

In order to facilitate the bag material 101 to be drawn out from the material winding roller 102, the bag feeding assembly of the embodiment further comprises a first driving structure connected with the material winding roller 102 to drive the material winding roller 102 to rotate; for example, in an alternative case, the first driving structure includes a first driving wheel 105 disposed at one end of the winding roller 102, a first driving chain 106 connected to the first driving wheel 105, and a first driving wheel 107 connected to one end of the first driving chain 106 away from the first driving wheel 105; wherein the first driving wheel 107 is connected with a first power structure suitable for driving the first driving wheel to rotate.

The bag 101 fed from the guide roll 103 is still planar, and is rolled into an arc-shaped configuration by the bag-rolling pipe 400.

Finally, the bag assembly comprises a through-connected double-cavity sleeve 500 which is suitable for forming a double-bag body after the bag material 101 is embedded, and a pair of symmetrically arranged hot sealing structures which are positioned below the double-cavity sleeve 500; one of the pair of heat seal structures is used for embedding the heat seal bag material 101 in the longitudinal opening 201 formed in the double-cavity sleeve 500, and the other heat seal structure is used for embedding the heat seal bag material 101 in the middle seam 202 formed in the double-cavity sleeve 500; specifically, for the planar bag material 101, the bag structure of one bag cavity can be formed by hot sealing the longitudinal opening 201 formed after the bag material is folded in half, and on the basis, the bag structure of two bag cavities can be formed by hot sealing the middle seam 202 position after the bag material is folded in half. It should be noted that, in the case of discharge pipe 9 inserted into double-lumen cannula 500, there is a gap between the outer wall of discharge pipe 9 and the inner wall of double-lumen cannula 500, so that bag material 101 is inserted between the inner wall of double-lumen cannula 500 and the outer wall of discharge pipe 9 to be curled into an arc-shaped configuration.

Still further referring to the drawings, the pair of ironing structures adopted in the present embodiment each include a pair of ironing wheels 301 disposed oppositely to be suitable for clamping two side end faces of the bag material 101 rolled into an arc shape, and a second driving structure respectively connected to the pair of ironing wheels 301 to drive the ironing wheels 301 to rotate.

It should be noted that, for a pair of ironing and sealing wheels 301 respectively located at two side end surfaces of the bag material 101, the rotation directions thereof are opposite, and the clamping of the two side end surfaces of the bag material 101 is realized through the opposite rotation directions, in this process, in addition to the ironing and sealing of the bag material 101, the bag material 101 can also be pulled by the ironing and sealing wheels 301, so that the bag material 101 is pulled out from the winding roller 102 by combining with the first power structure connected with the winding roller 102, and then the bag material 101 sequentially passes through the guide roller 103 and the bag rolling structure and enters the bag forming assembly to form a bag body structure with two bag cavities.

Regarding the pair of hot sealing structures of the present embodiment, in the two hot sealing wheels 301 respectively included in the pair of hot sealing structures, the two hot sealing wheels 301 located on the same side of the bag material 101 may be sleeved on the same connecting shaft 302, and the rotation of one hot sealing wheel 301 of the pair of hot sealing structures is realized by the connecting shaft 302, so that the structure can be simplified. And a heating rod 305 is arranged in the connecting shaft 302 so that the hot sealing wheel 301 can form a hot sealing effect on the surface of the bag material 101. That is, the pair of heat sealing structures of the present embodiment requires two connecting shafts 302 in total.

The rotary drive for the coupling shaft 302 can be realized by the following structure:

the two connecting shafts 302 are respectively connected with a driving shaft 303, namely, a total of two driving shafts 303 are needed, and optionally, a heat insulation sleeve is arranged at the connecting part of the connecting shafts 302 and the driving shafts 303; the two driving shafts 303 are respectively and fixedly sleeved with a gear disc 306, the gear discs 306 sleeved on the two driving shafts 303 are in a meshed relation, and at the moment, the rotation of the two driving shafts 303 can be realized only by realizing the rotation driving of one gear disc 306 through a belt wheel structure 307 and a motor 308, for example, but not limited to.

In summary, the packaging mechanism of the present embodiment: by sending a bag subassembly output bag material 101, through roll up bag structure with planar bag material 101 batching arc form, form the bag body that has two pockets at last by the bagging subassembly again, so can two pockets of one shot forming, also can pack two work pieces 2000 simultaneously to improve work piece 2000's packing efficiency.

Next, more specifically, the workpiece conveying mechanism of the present embodiment includes: the automatic stacking and discharging device comprises a workpiece conveying disc 7001 in a disc-shaped structure, a workpiece output disc 7002 in a disc-shaped structure, and a plurality of stacking and discharging assemblies 4, wherein the workpiece conveying disc 7001 is coaxially arranged with the workpiece conveying disc 7001, the workpiece output disc 7002 is arranged below the workpiece conveying disc 7001 in the disc-shaped structure, and the stacking and discharging assemblies 4 are arranged between the workpiece conveying disc 7001 and the workpiece output disc 7002 at intervals along the circumferential direction of the workpiece conveying disc 7001; and a feed pipe 8000 corresponding to the stacked discharging assembly 4 is also provided above the workpiece transfer tray 7001.

The workpiece transport tray 7001 in detail next:

the workpiece transport tray 7001 is adapted to make a circular motion. The stacking and discharging assembly 4 is synchronously driven to do circular motion in the process of making circular motion of the workpiece conveying disc 7001. And two workpiece transfer units which are concentrically distributed and have an annular structure and are correspondingly matched with the stacking discharge assemblies 4 one by one are arranged on the workpiece conveying disc 7001, and in the circular motion process of the workpiece conveying disc 7001, the two workpiece transfer units respectively and independently realize the transfer conveying operation of the workpieces 2000.

Further, the work output tray 7002 of the present embodiment:

in the case where two work transfer units are provided on the work transfer tray 7001 in the drawing, two discharge ports 7003 concentrically arranged one by one in correspondence with the two work transfer units are provided on the work output tray 7002, and one discharge pipe 9 is connected to each discharge port 7003. That is, for the plurality of stacked outfeed assemblies 4 corresponding to each workpiece transfer unit, the plurality of stacked outfeed assemblies 4 sequentially communicate with the outfeed opening 7003 with the circular movement of the workpiece transport tray 7001 to finally discharge the workpiece 2000 from the outfeed opening 7003 into the outfeed pipe 9.

Furthermore, a feeding pipe 8000 corresponding to the stacking and discharging assembly 4 is arranged above the workpiece conveying disc 7001, and the workpiece 2000 is thrown into the feeding hole of the first material passing pipe 1000 through the feeding pipe 8000 and finally discharged out of a discharging hole 7003 on the workpiece output disc 7002.

It should be noted that, in the present embodiment, the stacked discharging assembly 4 is fixedly connected to the end face of the workpiece transfer tray 7001 facing the workpiece output tray 7002, and the stacked discharging assembly 4 itself is in contact fit with the workpiece output tray 7002 or is not in direct contact but has a slight gap, because even if a slight gap exists, the entry of the workpiece 2000 into the discharging opening 7003 is not affected, and this embodiment is not limited in any way.

Further, the work output tray 7002 of the present embodiment is configured to be coaxially distributed with the work conveyance tray 7001 by the connection shaft 5, but the work output tray 7002 is rotationally engaged with the connection shaft 5 by, for example, a bearing structure; and the workpiece transfer tray 7001 is fixedly connected with the connecting shaft 5, that is, during the process that the workpiece transfer tray 7001 makes circular motion along with the connecting shaft 5, the workpiece output tray 7002 is kept relatively static relative to the connecting shaft 5 and does not rotate along with the connecting shaft 5. With such a structure, the circular motion of the workpiece conveying disc 7001 can be realized only by the power structure capable of driving the connecting shaft 5 to rotate, the power structure in this embodiment is not absolutely limited, and may be the matching between the gear 6 sleeved on the connecting shaft 5 and a speed reduction motor assembly adapted to drive the gear 6 to rotate, and with reference to the attached drawings, the speed reduction motor assembly in this embodiment includes a transmission gear 71 engaged with the gear 6, a driving wheel (not shown in the drawings, and disposed in the housing) coaxially connected with the transmission gear 71, a synchronous belt structure 73 connected with the driving wheel, and a second driving motor 74 connected with the synchronous belt structure 73.

It will be further described that, during the packaging of the workpieces 2000, the discharge rate of the workpieces 2000 from the stack discharge assembly 4 to the discharge opening 7003 needs to be controlled so that the workpieces 2000 discharged from each discharge opening 7003 can be packaged one by one, thereby avoiding the problem of two workpieces 2000 entering the same packaging bag. In this case, for the automatic packaging device, in the transmission process before the workpiece 2000 is packaged, if there is no control in the transmission process of the workpiece 2000, it is easy to cause two or even a plurality of workpieces 2000 to enter into one packaging bag, which not only causes confusion of the process, but also may cause the packaging process to malfunction, thereby affecting the stability and the service life of the device.

Therefore, based on the above problems, the present embodiment employs the following specific structure of the stack discharging assembly 4:

It should be noted that, in consideration of the effective blocking effect of the bosses 3003 of the pair of stop rings on the workpiece 2000, the bosses 3003 of the pair of stop rings in this embodiment correspond to the 1/4-1/2 circles of the hollow material passing cavity 1001, that is, in an alternative implementation, the bosses 3003 of the pair of stop rings may be directly joined together to form a circular structure conforming to the inner cavity wall of the hollow material passing cavity 1001, that is, the boss 3003 of any one stop ring at this time is a semicircular structure corresponding to the hollow material passing cavity 1001.

It should be further noted that, in the present embodiment, the top end and the bottom end of the workpiece 2000 to be transported respectively have annular chamfer structures 2001, the boss 3003 of the present embodiment extends from the inner cavity wall of the hollow material passing cavity 1001 to the corresponding chamfer structures 2001 of the two longitudinally stacked workpieces 2000, that is, the chamfer structures 2001 respectively provided on each of the two longitudinally stacked workpieces 2000 form an interval suitable for the boss 3003 to extend into, so that a barrier for the two workpieces 2000 can be formed.

On the basis of the above structure, in further detail, the limiting ring adopted in this embodiment includes a body 3001 movably embedded in the inner wall of the first material passing pipe 1000, an engaging ring integrally connected with the outer circumferential surface of the body 3001, and a stop ring 3002 integrally connected with the inner circumferential surface of the body 3001; the boss 3003 is arranged on the side end face of the stop ring 3002 facing the hollow material passing cavity 1001; and a recessed groove 3008 is formed by the engagement ring and the stop ring 3002 with respect to the body 3001. That is, the body 3001 and the engagement ring cooperate with the inner cavity wall of the hollow material passing cavity 1001 to achieve the blocking effect of the projection 3003 on the stop ring 3002 on the circulation process of the workpiece 2000.

In addition, the material limiting structure adopted by the embodiment further comprises a first elastic structure and a second elastic structure. Specifically, the first elastic structure includes arc-shaped elastic bodies 4001 disposed between the limiting ring and the first material passing pipe 1000 in a one-to-one correspondence manner; the arc-shaped elastic body 4001 partially protrudes from the feeding hole of the first material passing pipe 1000; and the specific arc elastomer 4001 is arranged between the side wall of the connecting ring corresponding to the top end of the connecting ring and the first material passing pipe 1000. The second elastic structure comprises arc-shaped elastic pieces 4002 which are arranged between the limiting ring and the first material passing pipe 1000 in a one-to-one correspondence manner; and the concrete arc elastic piece 4002 is arranged between the side wall of the connecting ring corresponding to the bottom end of the connecting ring and the first material passing pipe 1000. Under such a structure, when the portion of the arc-shaped elastic body 4001 protruding from the feeding hole of the first feeding pipe 1000 is pressed from one axial end, the arc-shaped elastic body 4001 is drawn into a space formed between the first feeding pipe 1000 and the adapter ring under the action of pressure, so that a pushing force on the adapter ring in the radial direction of the hollow feeding cavity 1001 can be generated by the arc-shaped elastic body 4001, and the stopper ring can move in the radial direction of the first feeding pipe 1000 to protrude the boss 3003 from the inner wall of the first feeding pipe 1000 toward the inner wall of the hollow feeding cavity 1001 to form a stopper for the workpiece 2000 outside the feeding hole of the first feeding pipe 1000. It should be noted that, for the arc-shaped elastic body 4001 of the present embodiment, in the process that the arc-shaped elastic body 4001 is gradually gathered into the space formed between the first material passing pipe 1000 and the engaging ring after being pressed, the maximum pressing degree of the arc-shaped elastic body 4001 is that the arc-shaped elastic body 4001 is pressed until the top end surface of the arc-shaped elastic body 4001 is flush with the end surface where the feeding hole of the first material passing pipe 1000 is located, so that the force applying component pressing the arc-shaped elastic body 4001 does not enter the space formed between the first material passing pipe 1000 and the engaging ring.

In addition, for the adapter ring of the present embodiment, the following structure is adopted:

the connecting ring comprises a base 3005 integrally connected with the body 3001 and an inner matching ring 3006 which is vertically connected with the base 3005 towards the pipe orifice end of the first material passing pipe 1000 and has a trapezoidal structure in section; the end face of the inner fitting ring 3006 facing away from the hollow material passing cavity 1001 is a tapered face abutting against the arc-shaped elastic body 4001, and the vertical distance between the abutting end of the inner fitting ring 3006 and the arc-shaped elastic body 4001 and the axis of the hollow material passing cavity 1001 is greater than the vertical distance between the end of the inner fitting ring 3006 connected with the base 3005 and the axis of the hollow material passing cavity 1001. With such a structure, the conical surface of the inner fitting ring 3006 is fitted with the arc-shaped elastic body 4001, so that the arc-shaped elastic body 4001 is pressed, so that the movement process of the arc-shaped elastic body 4001 along the axial direction parallel to the hollow material passing cavity 1001 can be converted into the movement process of the engaging ring, namely the limiting ring along the radial dimension of the hollow material passing cavity 1001. And the side end face of base 3005 deviating from body 3001 then butts with arc elastic component 4002, under such structure for the motion process of spacing ring along the radial dimension of cavity 1001 is crossed to the cavity, and arc elastic component 4002 is by tensile deformation, and at this moment, after the roof pressure effect to arc elastic component 4001 disappears, the spacing ring can realize automatic re-setting under arc elastic component 4002's elasticity restoring effect.

It is to be noted that the specific structure of the assembly between the first material passing tube 1000 and the limiting ring is as follows:

an assembly groove 1002 for assembling a limiting ring is concavely arranged at the feed inlet of the first material passing pipe 1000, and an arc-shaped embedded part 1003 suitable for being embedded into the concave groove 3008 is arranged in the assembly groove 1002; a yielding part 1006 suitable for being embedded into the stop ring 3002 is formed between the arc-shaped embedded part 1003 and the inner wall of the hollow material passing cavity 1001 corresponding to the first material passing pipe 1000; and the feed inlet of the first material passing pipe 1000 is further provided with a movable groove which is communicated with the assembling groove 1002 and is used for being embedded into the arc-shaped elastic piece 4002. It should be noted that the arcuate insert 1003 and the recessed groove 3008 are limited only along the axial layer of the hollow material passing cavity 1001, and do not limit the movement of the retainer ring along the radial layer of the hollow material passing cavity 1001, that is, the arcuate insert 1003 and the recessed groove 3008 are in clearance fit, that is, the fit clearance between the two is the space required for the operation of the radial dimension of the retainer ring.

In summary, the specific implementation principle of the stacking discharge assembly 4 of the present embodiment is as follows:

the arc-shaped elastic body 4001 is pressed against the part protruding out of the feeding hole of the first material passing pipe 1000, so that the movement process of the arc-shaped elastic body 4001 along the axial direction parallel to the hollow material passing cavity 1001 is converted into the movement process of the connecting ring, namely the movement process of the limiting ring along the radial dimension of the hollow material passing cavity 1001, in the process, the boss 3003 on the limiting ring forms that only one workpiece 2000 can enter the hollow material passing cavity 1001, and the rest workpieces 2000 can only be isolated outside the feeding hole of the first material passing pipe 1000 above the limiting ring. Specifically, the boss 3003 extends from the inner cavity wall of the hollow material passing cavity 1001 to the corresponding chamfer structures 2001 of the two longitudinally stacked workpieces 2000, that is, the chamfer structures 2001 respectively provided on each of the two longitudinally stacked workpieces 2000 form an interval suitable for the boss 3003 to extend into, so that a barrier can be formed for the two workpieces 2000.

On the basis of the above structure, further, the end surface of the feeding pipe 8000 facing to the pipe orifice of the first material passing pipe 1000 of the stacking material discharging assembly 4 is provided with a top ring 8001 suitable for pushing the arc-shaped elastic body 4001; and the feed tube 8000 is also coupled to a dither drive assembly adapted to dither the feed tube 8000. In an alternative embodiment, the dither drive assembly includes a support post 9001 secured to the feed tube 8000, and a cylinder 9002 coupled to the support post 9001. The shaking driving component can shake the feeding pipe 8000 to prevent the workpiece 2000 in the feeding pipe 8000 from blocking, and the feeding pipe 8000 can press the arc elastomer 4001 under the action of the shaking driving component; thus, the use requirement of the invention can be satisfied at one stroke by the simplified structure.

Example 3:

referring to fig. 11 to 15, on the basis of the workpiece conveying and packaging device of embodiment 2, the workpiece conveying and packaging device of this embodiment further includes a second material passing pipe 5000 in sleeve fit with the first material passing pipe 1000; the second material passing pipe 5000 is provided with a hollow cavity 5001 communicated with the hollow material passing cavity 1001; the first through pipe 1000 is inserted into the second through pipe 5000 from the pipe orifice of the second through pipe 5000; it should be noted that, in the present embodiment, the axial depth of the hollow cavity 5001 of the second material passing pipe 5000 is greater than the axial depth of the hollow material passing cavity 1001 of the first material passing pipe 1000, and with such a structure, the axial depth of the whole stacked material discharging assembly 4 of the present embodiment for flowing through the workpiece 2000 is greater than the axial depth of the whole stacked material discharging assembly 4 of the embodiment 1 for flowing through the workpiece 2000.

The outer wall of the second through pipe 5000 in this embodiment is fixedly connected with the workpiece conveying tray 7001 so as to realize the matching and fixing of the stacked discharging assembly 4 and the workpiece conveying tray 7001.

It should be noted that, for the stacked discharging assembly 4 of embodiment 2, in order to effectively achieve the effect that the workpieces 2000 enter the hollow material passing cavity 1001 of the first material passing pipe 1000 one by one, the axial depth of the hollow material passing cavity 1001 of the first material passing pipe 1000 in the stacked discharging assembly 4 of embodiment 1 matches with the axial length of the workpieces 2000, that is, when the boss 3003 extends into the chamfering structure 2001 between two longitudinally stacked workpieces 2000, the bottom of the lower workpiece 2000 that has entered the hollow material passing cavity 1001 is just flush with the bottom end of the hollow material passing cavity 1001, so that the use requirement can be met. Therefore, the stacked discharging assembly 4 in embodiment 2 can only be used by matching the first material passing pipe 1000 of one specification and size with one workpiece 2000, and when the discharging regulation and control of workpieces 2000 of different specification and size are required, the first material passing pipe 1000 needs to be replaced, so that the application range of the stacked discharging assembly 4 in this case is narrow. Therefore, the second material passing pipe 5000 matched with the first material passing pipe 1000 is used for realizing adaptability to workpieces 2000 with different specifications and sizes, so that the application range of the stacking material discharging assembly 4 of the embodiment is widened. That is, in this embodiment, the axial depth of the hollow cavity 5001 of the second material passing pipe 5000 is greater than the axial length of the largest-sized workpiece 2000 in a certain specification and size range, and the axial depth of the hollow material passing cavity 1001 of the first material passing pipe 1000 at this time is less than or equal to the axial length of the smallest-sized workpiece 2000 in a certain specification and size range.

Specifically, a plurality of L-shaped elastic pieces 6000 are arranged between the bottom end of the first material passing pipe 1000 and the inner cavity wall of the hollow cavity 5001 of the second material passing pipe 5000 at intervals along the circumferential direction of the first material passing pipe 1000. It should be noted that the included angle formed between the two wing arms of the L-shaped elastic piece 6000 is an obtuse angle structure. And the inner cavity wall of the hollow cavity 5001 is provided with an annular step 5002 suitable for supporting the L-shaped elastic sheet 6000. One of the wing arms of the L-shaped elastic piece 6000 is located between the outer sidewall of the first material passing tube 1000 and the inner sidewall of the hollow cavity 5001, and the other wing arm of the L-shaped elastic piece 6000 is located between the bottom end of the first material passing tube 1000 and the step portion 5002, and the end of the wing arm located between the bottom end of the first material passing tube 1000 and the step portion 5002 is suitable for partially extending into the interval of the hollow cavity 5001 corresponding to the circulating workpiece 2000, that is, the L-shaped elastic piece 6000 can form an obstruction effect on the circumferential layer of the workpiece 2000 circulating in the hollow cavity 5001.

In addition to the above structure, the first material passing pipe 1000 according to the present embodiment includes a tubular body 1004 and annular fins 1005 integrally provided on the circumferential side of the distal end portion of the tubular body 1004; an accommodating groove 5003 communicated with the hollow cavity 5001 and used for accommodating the annular wing 1005 is formed in the hollow cavity 5001 from the pipe orifice of the second material passing pipe 5000 inwards; and the annular wing 1005 is adapted to reciprocate along the axial direction of the receiving groove 5003; and when the annular fin 1005, i.e., the first material passing tube 1000, performs the axial reciprocating movement, the tubular body 1004 is driven to perform the synchronous movement to press and release the L-shaped elastic piece 6000.

Specifically, when the first material passing tube 1000 moves toward the L-shaped elastic piece 6000, the first material passing tube 1000 generates a pressing force on the wing arm between the bottom end of the first material passing tube 1000 and the step portion 5002 in the L-shaped elastic piece 6000, so that the wing arm deforms and withdraws from the end portion of the section of the hollow cavity 5001 corresponding to the circulating workpiece 2000, that is, the workpiece 2000 cannot be blocked by the L-shaped elastic piece 6000 in the hollow cavity 5001 and can smoothly circulate.

The power for the annular wing 1005 to reciprocate along the axial direction of the accommodating groove 5003 is the power from the shaking driving assembly, namely the shaking driving assembly or the first material passing pipe 1000 to move towards the L-shaped elastic sheet 6000; therefore, the shaking driving component can meet the using requirement of the invention by three steps through the simplified structure.

In summary, the specific use principle of the workpiece conveying mechanism of the workpiece conveying and packaging device in this embodiment is as follows:

during the circular motion of the workpiece transport tray 7001, when the feed pipe 8000 is aligned with the feed opening of the first through pipe 1000 of the stacked discharge assembly 4 on the workpiece transport tray 7001, at this point, the workpiece transfer pallet 7001 stops its circular motion, the feed pipe 8000 is depressed by the cylinder 9002, so that the top ring 8001 on the feeding pipe 8000 presses the arc-shaped elastomer 4001 to protrude from the part of the feeding hole of the first material passing pipe 1000, so that the movement process of the arc-shaped elastomer 4001 along the axial direction parallel to the hollow material passing cavity 1001 is converted into the movement process of the connecting ring, namely the limiting ring along the radial dimension of the hollow material passing cavity 1001, in the process, the boss 3003 on the limiting ring forms that only one workpiece 2000 can enter the hollow material passing cavity 1001, and the rest of the workpieces 2000 can only be isolated outside the feed inlet of the first material passing pipe 1000 above the limiting ring, so that the separation effect between two longitudinally stacked workpieces 2000 is realized. Specifically, the boss 3003 extends from the inner cavity wall of the hollow material passing cavity 1001 to the corresponding chamfer structures 2001 of the two longitudinally stacked workpieces 2000, that is, the chamfer structures 2001 respectively provided on each of the two longitudinally stacked workpieces 2000 form an interval suitable for the boss 3003 to extend into, so that a barrier can be formed for the two workpieces 2000.

In the above process, the bottom end of the workpiece 2000 entering the hollow cavity 5001 is directly mounted on the wing arm of the L-shaped shrapnel 6000, or the axial side wall of the workpiece 2000 is clamped and clamped by the wing arm of the L-shaped shrapnel 6000; after the arc-shaped elastic body 4001 is completely pressed to the bottom, the cylinder 9002 acts on the feeding pipe 8000, the top ring 8001 of the feeding pipe 8000 is pushed to the first material passing pipe 1000 through the transition connection of the arc-shaped elastic body 4001, so that the first material passing pipe 1000 moves towards the L-shaped elastic piece 6000 and the wing arm deforms to withdraw the end portion of the interval which originally extends into the hollow cavity 5001 and corresponds to the circulating workpiece 2000, and the workpiece 2000 can not be blocked by the L-shaped elastic piece 6000 in the hollow cavity 5001 to smoothly circulate.

In the process, the air cylinder 9002 lifts the feeding pipe 8000 to reset the first material passing pipe 1000, and after the first material passing pipe 1000 is reset to the right position, the air cylinder 9002 continues to lift, at the moment, the arc-shaped elastic body 4001 gradually recovers, in the process, the workpiece conveying disc 7001 starts to rotate circumferentially synchronously, so that the workpiece 2000 which cannot enter the first material passing pipe 1000 leaves the first material passing pipe 1000 of the previous stacked material discharging assembly 4 along with the operation of the workpiece conveying disc 7001, and is conveniently fed into the first material passing pipe 1000 of the next stacked material discharging assembly 4. In this process, the workpieces 2000 are temporarily stored in the hollow cavity 5001 of the stacked material discharge assembly 4, and the workpiece transport tray 7001 is operated so that the workpieces 2000 originally temporarily stored in the hollow cavity 5001 of the stacked material discharge assembly 4 can be discharged from the material discharge opening 7003 when the stacked material discharge assembly 4 corresponds to the material discharge opening 7003.
