Description

Technical Field

[0001] The invention relates to the technical field of plastic bottle annular load conveying and bottle unscrambling, and in particular to a plastic bottle annular load conveying and bottle unscrambling system. Background Art

[0002] At present, in various fields involving plastic bottle filling, such as food processing and pharmaceutical processing, it is necessary to use a bottle unscrambler to sort the plastic bottles so that they are evenly arranged, and the openings of the plastic bottles face upward to facilitate subsequent filling and capping operations.

[0003] According to patent No. CN113264348A, the publication (announcement) date is: 2021-08-17, an automatic bottle unscrambling device for plastic bottles is disclosed, including: a bottle unscrambling bin, which is a chamber with an open top, and a circular shell is provided in the bottle unscrambling bin, and the angle between the axis of the circular shell and the horizontal plane is 60 to 80 degrees, and a bottle outlet is opened on the side of the highest point of the circular shell; a main shaft is installed in the center of the circular shell and is coaxial with the circular shell; a turntable is installed on the main shaft and has the freedom of rotation, the turntable is a geared disc, and the tooth grooves on the geared disc are used to clamp the bottle body, and the tooth grooves constrain the height of the plastic bottle to be less than the length of the bottleneck of the plastic bottle and greater than or equal to 5 cm; a conveyor line is installed at the bottle outlet, used to guide and convey the plastic bottles out; a first drive mechanism is used to drive the turntable to rotate.

[0004] In the prior art including the above patent, the disordered plastic bottles can be evenly arranged by using a bottle unscrambler for subsequent filling operations. Fig.10 The guide frame d shown in the figure and the guide plate a rotating on the guide frame d, while using the notches b arranged in a circular array on the outer wall of the guide plate a, the bottle unscrambler is used to push the sorted plastic bottles c to squeeze into the notches b, and then during the rotation of the guide plate a, the two adjacent notches b on the guide plate a are located on the same axis, as shown in FIG. Fig.10 The guide plate a is rotated in the direction of the arrow X shown in the figure, and then the filling machine moves down in the vertical direction to fill the two plastic bottles c on the same axis. In order to avoid the outer wall of the plastic bottle c being scratched due to excessive friction between the plastic bottle c and the guide frame d and the smoothness of the rotation of the guide plate a, a certain gap is left between the guide plate a and the guide frame d, thereby avoiding the problems of squeezing and pinching of the plastic bottle c caused by the close distance between the guide plate a and the guide frame d. However, due to the gap between the guide plate a and the guide frame d, the filling machine is prone to squeezing and colliding with the bottle mouth of the plastic bottle c during the downward movement of the filling machine, thereby affecting the quality of the plastic bottle c to a certain extent. At the same time, the number of single fillings using the rotation of the guide plate a is limited. Summary of the invention

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] like Figure 1-10 As shown, a plastic bottle annular load conveying and unscrambling system comprises a symmetrically arranged stand 1 and a conveying chain belt movable between the two, and the conveying chain belt comprises:

[0046] There are multiple hinge plates 5, and every two hinge plates are hinged to each other to form a ring;

[0047] A boss 51 is provided on the conveying surface of the hinge plate 5;

[0048] A clamping plate assembly symmetrically disposed on opposite sides of the boss 51;

[0049] It also includes a conveyor belt 42 that is rotatably arranged on the top of the two stands 1. The conveyor belt 42 keeps synchronization with the conveyor chain belt, and the clamping plate group is driven along with the hinge plate 5 to switch between the following two stations:

[0050] At station 1, when the hinge plate 5 and the top of the stand 1 are located at the same horizontal plane, the clamping plate group clamps the plastic bottle 2 set on the top of the hinge plate 5, and the clamping plate group squeezes and pushes the plastic bottle 2 to make it located in the limiting groove 43 opened on the conveyor belt 42;

[0051] At station two, when the hinge plate 5 and the top of the stand 1 are not located in the same horizontal plane, the clamping plate group is released.

[0052] Specifically, the limit groove 43 and the hinge plate 5 match each other, and the conveyor belt 42 and the conveyor chain belt keep synchronization during the transmission of the hinge plate 5, so that the limit groove 43 corresponds to the hinge plate 5 in sequence. The clamping plate group is a clamping plate member 6 symmetrically hingedly arranged on the boss 51, and the clamping plate member 6 is accommodated in the boss 51 in the default state. The driving roller 3 and the driven roller 31 are rotatably arranged between the two vertical platforms 1, and the hinge plate 5 is movably arranged on the driving roller 3 and the driven roller 31. The tops of the two vertical platforms 1 are respectively rotatably arranged with a main conveying roller 4 and an auxiliary conveying roller 41, and the conveyor belt 42 is movably arranged on the main conveying roller 4 and the auxiliary conveying roller 41. A guide plate 11 is fixedly installed on one side of the top of the two stands 1 close to the driving roller 3, and a main inlet 12 and two branch channels 13 connected to the main inlet 12 are provided on the guide plate 11. The two branch channels 13 are matched with the opposite sides of the boss 51 respectively, that is, the opposite sides of the boss 51 are located at the outlet positions of the two branch channels 13, so that the diverted plastic bottle parts 2 can move to the hinge plate 5 and move synchronously with the hinge plate 5.

[0053] Then, the plastic bottles 2 pushed by the bottle unscrambler and other equipment along the main entrance 12 are diverted under the guidance of the two diversion channels 13, and then accompanied by the transmission of the hinge plate 5, the plastic bottles 2 are respectively located on the hinge plate 5 and on the opposite sides of the boss 51, and then under the transmission of the hinge plate 5, the multiple plastic bottles 2 are respectively located at the first station of the hinge plate 5. At this time, the multiple plastic bottles 2 are located at the same level, and are clamped and pushed by the two clamping plate members 6 of the clamping plate group, so as to limit the position of the plastic bottles 2, and The plastic bottle 2 is pushed into the limiting groove 43 for positioning under the clamping of the two clamping members 6. At this time, the limiting groove 43 is positioned to keep multiple plastic bottle members 2 on the same axis, so that the filling machine can be used for precise filling operations. After the filling of the plastic bottle 2 is completed, the hinge plate 5 is located in the second station. At this time, the hinge plate 5 and the top of the stand 1 are not located in the same horizontal plane. At the same time, the two clamping members 6 of the clamping group release the clamping of the plastic bottle 2 to facilitate the subsequent movement of the plastic bottle 2 for capping and other operations.

[0054] By using multiple plastic bottles 2 on the hinge plate 5, the efficiency of filling is accelerated, and the conveyor belt 42 and the conveyor chain belt are synchronized to reduce the friction and scratches on the plastic bottle 2 when transporting the plastic bottle 2. In addition, by placing the plastic bottle 2 on opposite sides of the boss 51, two production lines are separated under the drive of the hinge plate 5, so as to increase the production line and speed up the processing of the plastic bottle 2 after filling.

[0055] Furthermore, the driving roller 3 and the driven roller 31 may drive the hinge plate 5 to transmit by a motor driving the driving roller 3 or the driven roller 31; or the driving roller 3 and the driven roller 31 may be driven by two motors at the same time; or any other method known to those skilled in the art to drive the driving roller 3 and the driven roller 31 to drive the hinge plate 5 may be adopted.

[0056] The main conveying roller 4 and the auxiliary conveying roller 41 may drive the conveyor belt 42 to transmit the power by means of a motor driving the main conveying roller 4 or the auxiliary conveying roller 41; or the main conveying roller 4 and the auxiliary conveying roller 41 may be driven by two motors at the same time; or the main conveying roller 4 and the auxiliary conveying roller 41 may be driven by means of any method known to those skilled in the art to drive the conveyor belt 42.

[0057] The two clamping plates 6 can flip and clamp the plastic bottle 2 by a motor, an electric push rod and a connecting rod, or any other method known to those skilled in the art.

[0058] Furthermore, a plurality of support rollers 33 arranged in a linear array are rotatably provided between the two stands 1, and the support rollers 33 are attached to the bottom of the hinge plate 5 which is kept at the same horizontal plane as the top of the stand 1, so as to support the hinge plate 5 during transmission.

[0059] In the above technical scheme, the plastic bottle parts 2 are moved along with the hinge plate 5 at the workstation one so that the multiple plastic bottle parts 2 are located on the same horizontal plane, and then the clamping plate group is used to squeeze and push the hinge plate 5 located on the same horizontal plane so that the plastic bottle parts 2 are embedded in the limiting groove 43 opened on the conveyor belt 42, and then under the clamping and squeezing of the clamping plate group and the limiting positioning of the limiting groove 43, the multiple plastic bottle parts 2 can be more accurately poured by the filling machine at the same time. The simultaneous pouring of multiple plastic bottle parts 2 improves the pouring efficiency, and the damage to the bottle body of the plastic bottle part 2 is reduced under the synchronous movement of the conveyor belt 42 and the hinge plate 5.

[0060] As an embodiment further provided by the present invention, it also includes a driving unit for driving the conveyor belt 42 and the hinge plate 5 to drive synchronously, and the driving unit includes:

[0061] The main shaft rod 32 is used to drive the hinge plate 5 and the two conveyor belts 42 at the same time.

[0062] Specifically, Figure 3 As shown, the main shaft 32 is fixedly installed on the driving roller 3 along the axis of the driving roller 3, and the main shaft 32 is rotatably set on the two vertical platforms 1, and the two main conveying rollers 4 are respectively fixedly installed with a first shaft 38 and a second shaft 35 that rotate on the vertical platform 1 along the axis, and the first end of the driving roller 3 and one end of the first shaft 38 are respectively fixedly installed with first wedge gears 37 that mesh with each other, and at the same time, the second end of the driving roller 3 and the outer wall of the second shaft 35 are respectively fixedly installed with second wedge gears 34 that mesh with each other, and one end of the second shaft 35 is fixedly installed on the output end of the main motor 36 fixedly installed in the vertical platform 1. Therefore, when the main motor 36 is used to drive the second shaft 35 to rotate, the main shaft 32 and the second shaft 35 are rotated synchronously under the action of the second wedge gear 34. At the same time, the main shaft 32 and the first shaft 38 are meshed through the first wedge gear 37, so that the first shaft 38 and the main shaft 32 are rotated synchronously. Then, under the action of the main motor 36, the second shaft 35, the main shaft 32 and the first shaft 38 are rotated synchronously, and then the two main conveying rollers 4 and the driving roller 3 are driven to rotate synchronously. Under the rotation of the two main conveying rollers 4 and the driving roller 3, the driven roller 31 and the two auxiliary conveying rollers 41 are matched, so that the hinge plate 5 is transmitted to the driving roller 3 and the driven roller 31, and the conveying belt 42 is transmitted to the main conveying roller 4 and the auxiliary conveying roller 41. At the same time, the transmission direction of the two conveying belts 42 is consistent with the hinge plate 5.

[0063] Then, when the driving roller 3 rotates to convey the hinge plate 5 , the conveyor belt 42 keeps synchronization with the hinge plate 5 in the conveyor chain belt to convey the plastic bottle 2 .

[0064] As another embodiment provided by the present invention, two branch channels 13 arranged between the two stands 1 are located on the transmission path of the hinge plate 5, and the symmetrically arranged clamping plate members 6 in the clamping plate group are respectively hinged on the boss 51, and the two clamping plate members 6 are flipped in turn to limit the plastic bottle member 2 in different positions, wherein:

[0065] The first clamping plate 6 is turned over to block the plastic bottle 2 discharged along the branch channel 13;

[0066] The second clamping plate 6 is turned over to move the plastic bottle 2 close to the limiting groove 43 .

[0067] Specifically, the plastic bottle 2 discharged along the two branch channels 13 moves to the hinge plate 5 in the transmission. When the plastic bottle 2 moves from the branch channel 13 to the hinge plate 5, the boss 51 on the hinge plate 5 corresponding to it and the first clamping plate 6 on the two sides of the boss 51 away from the branch channel 13 are flipped, so as to block and limit the plastic bottle 2 sliding onto the hinge plate 5. At this time, the boss 51 on the two sides corresponds to the limiting grooves 43 on the top conveyor belts 42 of the two vertical platforms 1 respectively. The first clamping plate 6 is flipped to make the plastic bottle 2 located on one side of the limiting groove 43, and then the second clamping plate 6 is flipped to move the plastic bottle 2 close to the limiting groove 43. At this time, the two clamping plate 6 are jointly squeezed and limited to make the plastic bottle 2 accurately embedded and fit on the inner wall of the limiting groove 43, so as to achieve precise alignment of the plastic bottle 2. At the same time, under the flipping and blocking of the first clamping plate 6, the plastic bottle 2 discharged along the branch channel 13 is blocked and limited, and the plastic bottle 2 between the two hinge plates 5 is separated, so that the subsequent plastic bottle 2 can accurately correspond to the limiting groove 43, avoiding the problem that the clamping plate 6 cannot move the plastic bottle 2 when the plastic bottle 2 moves to the connection between the two hinge plates 5, or the clamping plate 6 squeezes the bottle body of the plastic bottle 2 when it is flipped and moved.

[0068] Furthermore, the two clamping plate members 6 are flipped over respectively to achieve accurate positioning, which facilitates the subsequent filling work of the filling machine.

[0069] The two clamping parts 6 can be turned over in sequence by two motors respectively; or by two electric push rods respectively pushing the two clamping parts 6 to turn over in sequence; or by any method known to those skilled in the art to drive the two clamping parts 6 to turn over in sequence.

[0070] As another embodiment provided by the present invention, force blocks 52 are slidably arranged at both ends of the boss 51, and the force blocks 52 respectively maintain transmission with the clamping parts 6 at the same position on the opposite sides of the boss 51. The elastic airbag 63 arranged on the moving path of the force block 52 is squeezed and deformed when the force block 52 moves.

[0071] Specifically, Figure 7 and Fig. 9As shown, transmission gears 71 are symmetrically arranged on both sides of the force block 52 in the boss 51, and the transmission gears 71 are respectively meshed with the main tooth openings 54 arranged on the outer walls of the opposite sides of the force block 52, and the force gear 72 is fixedly installed on the hinge shaft of the clamping plate 6, and double-sided gear rods 7 are symmetrically slidably arranged on both sides of the force block 52 in the boss 51, and the double-sided gear rods 7 are located between the transmission gear 71 and the force gear 72 and are respectively meshed with the transmission gear 71 and the force gear 72.

[0072] Therefore, when it is necessary to control the first clamping piece 6 on the opposite sides of the boss 51 to flip, the force block 52 corresponding to the first clamping piece 6 is driven to slide, so that the main tooth mouth 54 on the force block 52 and the transmission gear 71 on the opposite sides of the force block 52 are engaged. At this time, the transmission gear 71 rotates to engage with the double-sided gear rod 7, and the double-sided gear rod 7 slides to engage with the force gear 72. At this time, the first clamping piece 6 located on the opposite sides of the control boss 51 is synchronously flipped to protrude from the side wall of the boss 51, thereby blocking and limiting the plastic bottle part 2 discharged along the diversion channel 13. At the same time, the elastic airbag 63 is squeezed and deformed due to the sliding of the force block 52.

[0073] When it is necessary to control the second clamping plate 6 on the opposite sides of the boss 51 to flip, the force blocks 52 corresponding to the second clamping plate 6 are driven to slide, so that the main tooth openings 54 on the force blocks 52 are meshed with the transmission gears 71 on the opposite sides of the force blocks 52, and then the transmission gears 71 rotate to mesh with the double-sided gear rods 7, and the double-sided gear rods 7 slide to mesh with the force gears 72. At this time, the second clamping plate 6 on the opposite sides of the control boss 51 is synchronously flipped to protrude from the side wall of the boss 51 and move the plastic bottle 2 close to the limit groove 43, and the elastic airbag 63 is squeezed and deformed. Therefore, by driving the two force blocks 52 in the boss 51 to slide, the clamping plate 6 on the opposite sides of the boss 51 can be synchronously controlled to flip.

[0074] The two force blocks 52 in the boss 51 can slide separately by two electric push rods; or by two motors in conjunction with gears and racks; or by driving the two clamping plates 6 to flip in sequence in a manner known to those skilled in the art.

[0075] As another embodiment provided by the present invention, an expansion airbag 61 is fixedly installed on one adjacent side of the two clamping plates 6 , and the two expansion airbags 61 expand to push the plastic bottle 2 when the two clamping plates 6 clamp the plastic bottle 2 .

[0076] Specifically, by utilizing the expansion airbag 61, when the two clamping plates 6 clamp the plastic bottle 2 to limit its position, the expansion airbag 61 is driven to expand so as to push the plastic bottle 2 toward the limiting groove 43, thereby making the plastic bottle 2 fit more closely to the inner wall of the limiting groove 43.

[0077] The expansion airbag 61 may be inflated by setting an airbag component connected to the two expansion airbags 61 between the two clamping parts 6, and squeezing the airbag component by flipping the two clamping parts 6, thereby expanding the expansion airbag 61; or the elastic airbag 63 may be connected to the expansion airbag 61, and then when the elastic airbag 63 is squeezed, the expansion airbag 61 expands; or any other method known to those skilled in the art to drive the expansion airbag 61 to expand is possible.

[0078] As the best embodiment provided by the present invention, the elastic airbag 63 is respectively connected to the expansion airbags 61 at the same position on the opposite sides of the boss 51, and the expansion airbags 61 expand when the clamping plate 6 is turned over.

[0079] Specifically, the elastic airbag 63 is fixedly mounted on the force block 52, and a T-slot 53 connected to the elastic airbag 63 is provided on the force block 52. Hoses 62 fixedly connected to the T-slot 53 are respectively provided on opposite sides of the force block 52, and one end of the hose 62 is fixedly connected to the expansion airbag 61.

[0080] Therefore, when the force block 52 slides, the transmission gear 71, the double-sided gear rod 7 and the force gear 72 are used to flip the splint part 6 and make the force block 52 squeeze the elastic airbag 63. At this time, since the elastic airbag 63 is squeezed, the gas in the elastic airbag 63 is squeezed into the expansion airbag 61 along the T-slot 53 and the hose 62 to expand the expansion airbag 61, so that the flipping of the splint part 6 is used to move the plastic bottle part 2, and the expansion of the expansion airbag 61 pushes the plastic bottle part 2 to move closer to the limiting groove 43, so that the plastic bottle part 2 fits more closely to the inner wall of the limiting groove 43.

[0081] Furthermore, by controlling the flipping angle of the splint part 6, the splint part 6 can be used to realize the movement and limitation of the plastic bottle part 2, and then the elastic airbag 63 is squeezed and the expansion airbag 61 is expanded to push the plastic bottle part 2 to move and embed into the limiting groove 43, so that the expansion airbag 61 can be used to achieve soft contact between the splint part 6 and the plastic bottle part 2, avoiding the quality problem of deformation of the plastic bottle part 2 caused by only squeezing and pushing the splint part 6.

[0082] As another embodiment provided by the present invention, when the hinge plate 5 moves along the bottom of the branch channel 13 to one side of the branch channel 13, the two force-bearing blocks 52 on the hinge plate 5 are squeezed in sequence, and the elastic airbag 63 is squeezed and deformed to store force.

[0083] Specifically, the flow channel 13 is located on one side of the driving roller 3. When the hinge plate 5 is driven along the driving roller 3, the hinge plate 5 passes under the flow channel 13 and moves upward to one side of the flow channel 13. Figure 4As shown, when the hinge plate 5 is driven on the driving roller 3, there is a certain angle between the two hinge plates 5, and the angles are used to keep the force blocks 52 between the two hinge plates 5 at a distance. Therefore, when the hinge plate 5 transitions from the inclined state to being on the same horizontal plane as the top of the stand 1, the force blocks 52 on the inclined hinge plate 5 are squeezed to squeeze the force blocks 52 on the same horizontal plane as the top of the stand 1 and adjacent to the inclined hinge plate 5, so that the force blocks 52 on the inclined hinge plate 5 are squeezed and slide. When the force blocks 52 on the inclined hinge plate 5 slide, the main tooth openings 54 on the sliding force blocks 52 are meshed with the transmission gears 71 on the opposite sides of the force blocks 52. The gear 71 is engaged with the toothed bar 7 and the toothed bar 72 is engaged with the toothed bar 73. At this time, the first toothed bar 71 is engaged with the toothed bar 73 on both sides of the control boss 51. At this time, the first toothed bar 71 is engaged with the toothed bar 73 on both sides of the control boss 51. At this time, the second toothed bar 71 is engaged with the toothed bar 7 and the toothed bar 72 is engaged with the toothed bar 73. At this time, the second toothed bar 71 is engaged with the toothed bar 7 and the toothed bar 72 is engaged with the toothed bar 73. At this time, the second toothed bar 71 is engaged with the toothed bar 7 and the toothed bar 72 is engaged with the toothed bar 73. The clamping plate 6 is synchronously flipped to protrude the side wall of the boss 51 and move the plastic bottle 2, so that the plastic bottle 2 is located on one side of the limiting groove 43 under the limitation of the two clamping plate members 6. At the same time, the two force blocks 52 on the hinge plate 5 are squeezed and slid to further squeeze the elastic airbag 63, so that the squeezed gas of the elastic airbag 63 is rushed into the expansion airbag 61 to make the expansion airbag 61 expand to push the plastic bottle 2 to move and embed into the limiting groove 43, thereby achieving the effect of positioning the plastic bottle 2.

[0084] Therefore, the effects of shielding, limiting, pushing and positioning the plastic bottle 2 are achieved by utilizing the movement of the hinge plate 5 and the cooperation between the plurality of hinge plates 5 .

[0085] As another embodiment provided by the present invention, when the hinge plate 5 and the top of the stand 1 are switched from the same horizontal plane, the two elastic air bags 63 on the hinge plate 5 are deformed and reset in sequence to push the force-bearing block 52 .

[0086] Specifically, by utilizing the symmetrically sliding force blocks 52 on the boss 51, when the hinge plate 5 moves along the bottom of the diversion channel 13 to one side of the diversion channel 13, the force blocks 52 between every two hinge plates 5 push and slide against each other, so that the two force blocks 52 on the boss 51 move into the boss 51 in turn, thereby compressing the two elastic air bags 63 in the boss 51 in turn to deform the elastic air bags 63.

[0087] Furthermore, as the hinge plate 5 moves on the driving roller 3 and the driven roller 31, the hinge plate 5 gradually moves away from the branch channel 13. After the plurality of hinge plates 5 are moved and are in the same horizontal plane with the top of the stand 1, the movement of the hinge plate 5 is stopped, and then the plastic bottles 2 on the plurality of hinge plates 5 on the horizontal plane are poured. After the pouring is completed, the hinge plate 5 is driven again to switch from being in the same horizontal plane with the top of the stand 1, and then the hinge plate 5 begins to move toward the side of the driven roller 31. At this time, the hinge plate 5 adjacent to the hinge plate 5 and located on the driven roller 31 is tilted. Because an angle is formed between the hinge plate 5 in the same horizontal plane with the top of the stand 1 and the hinge plate 5 tilted on the driven roller 31, the gap between the hinge plate 5 and the adjacent hinge plate 5 is increased. At this time, due to the increase in the gap The force blocks 52 on the two adjacent hinged plates 5 are deformed and reset by the elastic airbag 63, pushing the force blocks 52, thereby causing the first clamping plate 6 on the hinged plate 5 on the same horizontal plane as the top of the stand 1 to flip over and be accommodated in the boss 51, thereby removing the obstruction of the plastic bottle part 2, and then with the movement of the hinged plate 5, the hinged plate 5 begins to move along the driven roller 31 and tilts. At this time, an angle begins to appear between the hinged plate 5 and its adjacent hinged plate 5 on the same horizontal plane as the top of the stand 1, and the gap between the hinged plate 5 and the adjacent hinged plate 5 increases. At this time, due to the increase in the gap, the force blocks 52 on the two adjacent hinged plates 5 are deformed and reset by the elastic airbag 63, pushing the force blocks 52 to slide, thereby causing the second clamping plate 6 on the hinged plate 5 to flip over and be accommodated in the boss 51.

[0088] Therefore, by moving the hinge plate 5 on the same horizontal plane as the top of the stand 1 and switching it to an inclined state, the first clamping plate 6 and the second clamping plate 6 are successively accommodated in the boss 51 to release the limiting effect on the plastic bottle 2, thereby facilitating the subsequent transportation of the released plastic bottle 2 to another production process.

[0089] As another embodiment further provided by the present invention, a shovel plate 17 located on the moving path of the hinge plate 5 is respectively provided on the top of the stand 1, and an arc-shaped guide plate 16 for guiding the movement of the plastic bottle 2 is provided on the shovel plate 17.

[0090] Specifically, Figure 8 As shown, the shovel plate 17 is fixedly mounted on the top of the stand 1, and the end of the shovel plate 17 is located on the moving path of the hinge plate 5, and the arc guide plate 16 is fixedly mounted on the top of the shovel plate 17, as shown in FIG. Figure 6 The arc-shaped guide plate 16 is located on one side of the conveyor belt 42 on the auxiliary conveyor roller 41 , and the shovel plate 17 is located above the driven roller 31 .

[0091] Furthermore, during the transmission of the hinge plate 5, the first clamping plate 6 and the second clamping plate 6 in the boss 51 are successively received in the boss 51 to release the limiting effect on the plastic bottle 2. Then, during the transmission and conveying process of the hinge plate 5, the plastic bottle 2 is squeezed and pushed and slides along the top surface of the shovel plate 17, so that the plastic bottle 2 is transported to the top of the stand 1 under the guidance of the arc guide plate 16, so as to facilitate subsequent processing and achieve the effect of diverting the plastic bottle 2.

[0092] As a further optimal embodiment of the present invention, when the hinge plate 5 and the top of the stand 1 are switched from the same horizontal plane, the two clamping plate members 6 located on the same side of the boss 51 are respectively located in two states, wherein:

[0093] One of the clamping plates 6 is turned over and stored in the boss 51;

[0094] Another clamping plate member 6 moves along with the hinge plate 5 to push the plastic bottle member 2 to slide on the shovel plate 17 .

[0095] Specifically, a side plate 14 is fixedly installed on the top of the stand 1 , and an extension rod 15 fixedly installed on the side plate 14 is located above the conveyor belt 42 , and the plastic bottle 2 moves between the side plate 14 and the arc-shaped guide plate 16 .

[0096] The plastic bottles 2 pushed by the bottle unscrambler and other equipment along the main entrance 12 are diverted under the guidance of the two branch channels 13, and then the main motor 36 is used to drive the second shaft 35 to rotate. At this time, under the action of the second wedge gear 34, the main shaft 32 and the second shaft 35 are rotated synchronously. At the same time, the main shaft 32 and the first shaft 38 are meshed through the first wedge gear 37, so that the first shaft 38 and the main shaft 32 are rotated synchronously, and then under the action of the main motor 36, the second shaft 35, the main shaft 32 and the first shaft 38 are rotated synchronously, and then the two main conveying rollers 4 and the driving roller 3 are driven to rotate synchronously. Under the rotation of the two main conveying rollers 4 and the driving roller 3, the driven roller 31 and the two auxiliary conveying rollers 41 are matched, so that the hinge plate 5 is transmitted to the driving roller 3 and the driven roller 31, and the conveyor belt 42 is transmitted to the main conveying roller 4 and the auxiliary conveying roller 41. At the same time, the transmission direction of the two conveyor belts 42 is consistent with the hinge plate 5.

[0097] Then, when the driving roller 3 rotates to convey the hinge plate 5, the conveyor belt 42 keeps synchronization with the hinge plate 5 in the conveyor chain to convey the plastic bottle 2. At this time, the plastic bottle 2 is discharged along the branch channel 13 along with the driving of the hinge plate 5. When the hinge plate 5 is driven along the driving roller 3, the hinge plate 5 passes under the branch channel 13 and moves up to one side of the branch channel 13. Figure 4 As shown, at this time, there is a certain angle between the two hinge plates 5, and the angles are used to keep the force blocks 52 between the two hinge plates 5 at a distance. Therefore, when the hinge plate 5 transitions from the inclined state to being on the same horizontal plane as the top of the stand 1, the force blocks 52 on the inclined hinge plate 5 are pressed against the force blocks 52 on the same horizontal plane as the top of the stand 1 and adjacent to the inclined hinge plate 5, so that the force blocks 52 on the inclined hinge plate 5 are pressed and slide. When the force blocks 52 on the inclined hinge plate 5 slide, the main tooth openings 54 on the sliding force blocks 52 mesh with the transmission gears 71 on the opposite sides of the force blocks 52. At this time, the transmission gear 71 rotates to engage with the double-sided gear rod 7, and makes the double-sided gear rod 7 slide and engage with the force-bearing gear 72. At this time, the first clamping plate 6 located on the opposite sides of the control boss 51 is synchronously flipped to protrude from the side walls of the boss 51. At this time, the plastic bottle parts 2 discharged along the two branch channels 13 move to the inclined hinge plate 5 and are respectively located on the opposite sides of the boss 51 on the hinge plate 5. At this time, the protruding first clamping plate 6 is used to block and limit the plastic bottle parts 2 and provide a certain supporting effect.

[0098] Then, the hinge plate 5 continues to move along with the tilt, and the hinge plate 5 switches to a state where it is located at the same horizontal plane as the top of the stand 1. Then, when the hinge plate 5 in the subsequent adjacent tilted state transitions to the same horizontal plane as the top of the stand 1, it squeezes another force-bearing block 52 of the hinge plate 5, so that the main tooth opening 54 on the force-bearing block 52 and the transmission gears 71 on the opposite sides of the force-bearing block 52 are meshed with each other under the movement of the other force-bearing block 52. At this time, the transmission gear 71 rotates to mesh with the double-sided gear rod 7, and the double-sided gear rod 7 slides to mesh with the force-bearing gear 72. At the same time, the second clamping plate members 6 located on the opposite sides of the control boss 51 are synchronously flipped to protrude from the side walls of the boss 51 and move the plastic bottle member 2, so that the plastic bottle member 2 is located on one side of the limiting groove 43 under the limitation of the two clamping plate members 6, and at the same time, the two force blocks 52 on the hinge plate 5 are squeezed and slid to further squeeze the elastic airbag 63, so that the squeezed gas of the elastic airbag 63 is rushed into the expansion airbag 61 to make the expansion airbag 61 expand to push the plastic bottle member 2 to move and embed into the limiting groove 43, thereby achieving the effect of positioning the plastic bottle member 2.

[0099] Furthermore, by driving the hinge plates 5 to drive multiple plastic bottles 2 to be located on the multiple hinge plates 5, and making these hinge plates 5 and the top of the stand 1 to be located at the same horizontal plane and all embedded in the limiting grooves 43, it is convenient to perform simultaneous and more precise infusion operations on multiple plastic bottles 2.

[0100] After the infusion is completed, the hinge plate 5 is driven again to switch from being on the same horizontal plane with the top of the stand 1, and then the hinge plate 5 starts to move toward the side of the driven roller 31. At this time, the hinge plate 5 adjacent to the hinge plate 5 and located on the driven roller 31 is tilted. Because an angle appears between the hinge plate 5 on the same horizontal plane with the top of the stand 1 and the hinge plate 5 tilted on the driven roller 31, the gap between the hinge plate 5 and the adjacent hinge plate 5 increases. At this time, due to the increase in the gap, the force blocks 52 on the two adjacent hinge plates 5 are deformed and reset by the elastic airbag 63 to push the force blocks 52, and then the first clamping plate 6 on the hinge plate 5 on the same horizontal plane with the top of the stand 1 is flipped to be stored in the boss 51, thereby removing the obstruction of the plastic bottle 2. Then, with the movement of the hinge plate 5, as shown in FIG. Figure 8 As shown, by utilizing the second clamping plate 6 and the hinge plate 5 that keep the side wall of the turned-out boss 51 to move synchronously to approach the shovel plate 17, the turned-out second clamping plate 6 is utilized to move the plastic bottle 2, so that the plastic bottle 2 can continue to remain embedded in the limiting groove 43, so that the plastic bottle 2 can continue to move with the conveyor belt 42 and be driven onto the shovel plate 17. At this time, the arc-shaped guide plate 16 is utilized to shield the plastic bottle 2, so that the plastic bottle 2 can remain embedded in the limiting groove 43 and be driven by the conveyor belt 42 to slide on the shovel plate 17, and then Figure 6 As shown in the figure, the extension rod 15 is used to block the plastic bottle 2 in the limiting groove 43, so that the plastic bottle 2 is separated from the limiting groove 43 under the obstruction of the extension rod 15, and then accompanied by the squeezing and pushing movement between multiple plastic bottle pieces 2, so as to facilitate subsequent operations such as capping.
