Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a quantitative packaging device for sodium gluconate products. Background Technology

[0002] Sodium gluconate belongs to the class of organic acid salts, specifically the sodium salt of gluconic acid. It is a carboxylate salt formed by the neutralization reaction of gluconic acid with sodium hydroxide, possessing the properties of both carboxylate and sodium ions. It is widely used in food, medicine, construction, and chemical industries.

[0003] Before sodium gluconate leaves the factory, it needs to be repackaged. Chinese utility model patent CN207258095U discloses an actuator for separating and transporting bags, including: a bag-pressing mechanism for separating the bag tail, a bag-feeding mechanism for suction cups and transporting the bag head, and a switching mechanism for bag replenishment. The bag-pressing mechanism first separates the tail of the outermost bag from the other bags and presses the tail of the remaining bags to ensure that the bag-feeding mechanism does not simultaneously suction the outermost bag. After the bag-pressing mechanism completes its operation, the bag head of the outermost bag is suctioned by the bag-feeding mechanism and transported to the next work position. When the bags are used up, the switching mechanism pushes pre-prepared bags to the work area for replenishment.

[0004] Although the above-mentioned device can achieve bag separation and conveying, its vacuum generator needs to keep supplying air in order to maintain the suction function of the suction cup, which consumes a lot of energy and poses a risk of bag falling off due to sudden air interruption.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Those skilled in the art will recognize that the invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by illustrating examples of it.

[0036] The directional terms used in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of the invention. It should also be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] like Figure 1 As shown, this invention provides a quantitative packaging device for sodium gluconate, comprising a bag feeding mechanism 1, a bag supporting mechanism 2, a filling mechanism 3, a bag supporting mechanism 4, and a storage platform 5. The storage platform 5 is used to temporarily store the packaging bags and continuously supply material to the bag feeding mechanism 1. The bag feeding mechanism 1 realizes automatic separation and conveying of the packaging bags, while the bag supporting mechanism 4 mechanically expands the bag opening to ensure unobstructed filling channels. The filling mechanism 3 completes the filling of sodium gluconate, and the bag supporting mechanism 2 stabilizes the bag body during filling and conveying, preventing tilting or collapse.

[0038] like Figure 2 and Figure 3 As shown, the bag feeding mechanism 1 includes a first frame 6. A horizontal plate 9 is fixed to one side of the first frame 6, and the horizontal plate 9 is horizontally arranged above the storage platform 5. A first cylinder 8 is vertically mounted on the top of the horizontal plate 9, forming a vertical lifting drive unit. The piston rod end of the first cylinder 8 is rigidly connected to the first mounting frame 10, driving it to move along the Z-axis. A mounting plate 13 is hinged to the bottom of the first mounting frame 10, and multiple sets of floating suction cups 12 are fixed on the mounting plate 13. The piston rod end of the second cylinder 11 is hinged to the mounting plate 13, and the cylinder body end of the second cylinder 11 is hinged to the first mounting frame 10. The second cylinder 11 adjusts the pitch angle of the mounting plate 13 through telescopic movement to realize the picking and conveying of packaging bags. An electric cylinder slide 7 is mounted on the top of the first frame 6, and a mounting frame 15 is fixed to the slide of the electric cylinder slide 7. Multiple sets of finger cylinders 16 that are inclined downward toward the floating suction cups 12 are fixed on the mounting frame 15.

[0039] like Figure 4As shown, the first frame 6 has a horizontally arranged platform 14. A drive roller 18 is installed on the lower end face of the platform 14, which is driven to rotate by a first motor 17 fixed to one side of the platform 14. An opening 19 is provided at the end of the platform 14 near the filling mechanism 3, allowing the drive roller 18 to be partially exposed, and the roller surface of the drive roller 18 contacts the packaging bag through the opening 19. A vertically arranged fourth cylinder 24 is mounted on the first frame 6 above the drive roller 18. The piston rod end of the fourth cylinder 24 is rigidly connected to the second mounting frame 25, driving it to move along the Z-axis. Multiple sets of rollers 20 are installed at the bottom of the second mounting frame 25, facing the drive roller 18, forming a clamping channel with the drive roller 18.

[0040] A lower mounting plate 21 is fixed to the side of the first frame 6 facing the filling mechanism 3. A third cylinder 23 is mounted on the side wall of the first frame 6. An upper mounting plate 22 is fixed to the piston rod end of the third cylinder 23, which is directly opposite the lower mounting plate 21. Multiple sets of floating suction cups 12 are symmetrically arranged on the lower mounting plate 21 and the upper mounting plate 22 to form an upper and lower clamping mechanism.

[0041] like Figure 5 As shown, the floating suction cup 12 consists of a suction cup body and a base body. The suction cup body and the base body are slidably connected and the air passage is opened through relative sliding.

[0042] The base includes a first spring 27, a cylinder 28, and a pressure cap 41. One end of the cylinder 28 has a fourth chamber 39, and the other end has a second chamber 36 communicating with the fourth chamber 39. The inner diameter of the second chamber 36 is smaller than the inner diameter of the fourth chamber 39. The pressure cap 41 is fixed to one end of the cylinder 28 to seal the fourth chamber 39. A rubber gasket 40 is added at the connection between the cylinder 28 and the pressure cap 41 to block the gas leakage path of the fourth chamber 39.

[0043] The pressure cap 41 has a quick connector 42 in the middle that connects to the fourth chamber 39, allowing for quick insertion and removal of the endotracheal tube with one hand. The fourth chamber 39 contains a perforated piston 38 with several through holes along its edge. A first spring 27 abuts against the perforated piston 38 and the pressure cap 41, causing the perforated piston 38 to rest against the cavity boss (the junction of the fourth chamber 39 and the second chamber 36). A sleeve 30 is fixed to the end of the perforated piston 38 facing the second chamber 36, and the outer wall of the sleeve 30 has multiple sets of second air holes 35 connecting to its inner cavity.

[0044] The suction cup body includes a mounting base 31 and a second spring 32. The mounting base 31 has a first chamber 34 extending through both ends. One end of the mounting base 31 passes through a second chamber 36 and is fixedly connected to the sleeve 30. The other end of the mounting base 31 is fixed with a suction cup 33. The outer diameter of the mounting base 31 is adapted to the inner diameter of the second chamber 36, and the interior of the second chamber 36 is provided with multiple sealing rings. The gap between the inner wall of the mounting base 31 and the outer wall of the sleeve 30 forms a third chamber 37. The outer wall of the mounting base 31 is provided with multiple sets of first air holes 29 communicating with the third chamber 37. The mounting base 31 has a flange, and the second spring 32 abuts against the flange and the sleeve 28.

[0045] The third chamber 37 serves as an airflow transfer chamber, balancing the pressure difference between the fourth chamber 39 and the first chamber 34 to prevent adsorption failure due to instantaneous pressure fluctuations.

[0046] Under the thrust, the lip of the suction cup 33 is pressed into contact with the surface of the packaging bag, and the cylinder 28 and the mounting base 31 slide relative to each other, compressing the first spring 27 and the second spring 32. The perforated piston 38 moves away from the cavity boss, the through hole is fully exposed, and the air passage is open. The external vacuum generator draws air through the quick connector 42, and the gas in the suction cup 33 is discharged through the first chamber 34, the inner cavity of the sleeve 30, the second air hole 35, the third chamber 37, the first air hole 29, the through hole, the fourth chamber 39, and the quick connector 42, forming a complete air passage. A vacuum seal is formed between the suction cup 33 and the packaging bag, completing the adsorption and locking.

[0047] After the thrust is removed, the first spring 27 and the second spring 32 return to their original positions simultaneously. The perforated piston 38 fits against the cavity boss, and the through hole and the first air hole 29 are respectively sealed by the cavity boss and the inner wall of the second chamber 36, interrupting the air passage. However, the first chamber 34 and the suction cup 33 still maintain negative pressure, achieving effective adsorption of the packaging bag.

[0048] like Figures 6 to 9 As shown, the bag-supporting mechanism 2 includes a support frame 46, which is installed on one side of the filling mechanism 3. The lower end face of the support frame 46 is slidably connected to a support plate 60 via a slide rail assembly 54, and the support plate 60 is provided with two sets of symmetrically arranged bag-supporting assemblies 47.

[0049] A second motor 44 is fixed to the end of the support frame 46 away from the filling mechanism 3, and a main synchronous pulley 49 is fixed to the output shaft of the second motor 44. A secondary synchronous pulley 52 is installed on one side of the support frame 46, and the secondary synchronous pulley 52 is connected to the main synchronous pulley 49 through a synchronous belt 51. A connecting block 55 is fixed to the body of the synchronous belt 51, and one end of the connecting block 55 is fixedly connected to the support plate 60.

[0050] The bag support assembly 47 includes a support arm 59 and a sixth cylinder 61. A baffle 57 is fixed to one end of the support arm 59, and two sets of first parallel linkage assemblies 56 are mounted on the other end of the support arm 59. The two sets of first parallel linkage assemblies 56 are mounted on both sides of the support plate 60. One end of the sixth cylinder 61 is hinged to the support plate 60, and the other end of the sixth cylinder 61 is hinged to one of the first parallel linkage assemblies 56. A clamping plate 58 is also fixed to the support arm 59, and the clamping plate 58 is located above the baffle 57.

[0051] A bag clamping assembly is also provided at the end of the support frame 46 away from the bag-holding assembly 47. The bag clamping assembly includes two sets of conveyor belt modules 48, which are symmetrically hinged to the lower end face of the support frame 46. A fifth cylinder 53 is hinged to one side of the conveyor belt module 48, and one end of the fifth cylinder 53 is hinged to the support frame 46. A linear gearbox 50 is fixed to the upper end face of the support frame 46. A third motor 45 is installed at the input end of the linear gearbox 50, and the two output ends of the linear gearbox 50 are respectively connected to the input ends of the two sets of conveyor belt modules 48.

[0052] like Figure 10 As shown, the filling mechanism 3 includes a second frame 43 and a first crossbeam 63. Stands 62 are fixed to both sides of the top of the second frame 43, and the first crossbeam 63 is slidably installed between the two sets of stands 62. A seventh cylinder 65 is installed on the top of each stand 62, and the piston rod end of the seventh cylinder 65 is fixedly connected to the first crossbeam 63. A hopper opening 64 for connecting to the hopper is fixed to the middle of the first crossbeam 63, and a gate control assembly 67 is provided at the bottom of the hopper opening 64. Bag clamping assemblies 66 are hinged to both sides of the bottom of the first crossbeam 63, and the two sets of bag clamping assemblies 66 are located on both sides of the gate control assembly 67.

[0053] like Figure 11 As shown, the bag clamping assembly 66 includes an eighth cylinder 68 and a support plate 70. A ninth cylinder 75 is fixed to the top of the support plate 70, and a connecting seat 71 is fixed to the piston rod end of the ninth cylinder 75. Clamping arms 73 are symmetrically hinged to both sides of the bottom of the support plate 70, and each clamping arm 73 is hinged to the connecting seat 71 via a first connecting rod 74. Anti-slip blocks 72 are fixed to one side of the end of each clamping arm 73, and the two sets of anti-slip blocks 72 are arranged in a relatively meshing layout. Second parallel connecting rod assemblies 69 are symmetrically installed on both sides of the top of the support plate 70, and the second parallel connecting rod assemblies 69 are mounted on the first crossbeam 63. The cylinder body end of the eighth cylinder 68 is hinged to the first crossbeam 63, and the piston rod end of the eighth cylinder 68 is hinged to one of the second parallel connecting rod assemblies 69.

[0054] like Figure 12As shown, the gate control assembly 67 includes two independently operating gates 76. The two gates 76 are symmetrically mounted on both sides of the bottom of the first crossbeam 63 via lateral hinges, forming a complete seal to the outlet of the chamber 64 when normally closed. Eleventh cylinders 79 are hinged to both sides of the first crossbeam 63, with the piston rod ends of each cylinder hinged to the drive lugs of the corresponding gate 76, forming a dual-cylinder synchronous push-pull mechanism to achieve precise opening and closing control of the gates. A pressure plate 77 is hinged to one side of each gate 76, and a tenth cylinder 78 is hinged to one side of the pressure plate 77, with one end of the tenth cylinder 78 hinged to the gate 76 on that side.

[0055] like Figure 13 As shown, the bag-supporting mechanism 4 includes a twelfth cylinder 85 and a fourth motor 86. The filling mechanism 3 has a second crossbeam 80. The fourth motor 86 is bolted to one end of the second crossbeam 80, and its output shaft is connected to a second rotating shaft 87 via a coupling. The second rotating shaft 87 is mounted on the second crossbeam 80 via a double-row bearing housing. Two sets of spaced straight arms 81 are fixed to the second rotating shaft 87. A first rotating shaft 82 is mounted between the two sets of straight arms 81 via deep groove ball bearings, with its two ends extending beyond the end faces of the straight arms 81 to form a cantilever structure. A fisheye connector is provided in the middle of the first rotating shaft 82. One end of the twelfth cylinder 85 is hinged to the fisheye connector, and the other end of the twelfth cylinder 85 is hinged to the inner wall of one of the straight arms 81. Insert plates 84 are fixed to both ends of the first rotating shaft 82, and bag-supporting assemblies 83 are fixed to the ends of the insert plates 84.

[0056] like Figure 14 As shown, the bag-supporting assembly 83 includes a thirteenth cylinder 92. The thirteenth cylinder 92, acting as a linear drive element, is mounted on the insert plate 84, providing the opening and closing power. A cover 90 is fixed to one end of the thirteenth cylinder 92, and pawls 88 are symmetrically hinged to both sides of the cover 90. A support plate 91 is fixed to one side of each pawl 88. The pawls 88 rotate around the hinge points on both sides of the cover 90, driving the support plate 91 to achieve the opening and closing action. A second connecting rod 89 is fixed to the output end of the thirteenth cylinder 92, forming a T-shaped connection structure. Both ends of the second connecting rod 89 are hinged to the pawls 88 on both sides, forming a double rocker mechanism.

[0057] The following are the specific working principles and technical details of the quantitative packaging equipment for this sodium gluconate product.

[0058] Packaging bags are stacked on storage platform 5, completing bag supply preparation. First cylinder 8 pushes mounting plate 13 downwards, using floating suction cups 12 to hold the topmost single packaging bag. Then, first cylinder 8 resets, and second cylinder 11 pushes mounting plate 13 to rotate around the hinge point, so that the edge of the packaging bag faces finger cylinder 16. Next, finger cylinder 16 closes, pneumatic jaws grip the edge of the packaging bag, and electric cylinder slide 7 drives mounting frame 15 to reset horizontally, removing the packaging bag and transferring it above platform 14. Finger cylinder 16 releases the bag, and the packaging bag falls freely onto platform 14.

[0059] The first motor 17 starts, driving the transmission roller 18 to rotate. The fourth cylinder 24 pushes the roller 20 to move down synchronously, forming a clamping channel with the transmission roller 18, moving the packaging bag towards the filling station, ensuring that the bag opening is transferred to the preset position between the lower mounting plate 21 and the upper mounting plate 22. The first motor 17 stops, and the fourth cylinder 24 resets and lifts the roller 20. The third cylinder 23 pushes the upper mounting plate 22 down, causing the floating suction cups 12 symmetrically arranged on the upper and lower mounting plates to respectively adhere to the upper and lower surfaces of the bag opening. The third cylinder 23 resets and lifts the upper mounting plate 22, and the bag opening is opened under the action of the suction force on both sides.

[0060] The twelfth cylinder 85 drives the first rotating shaft 82 to rotate around its axis, and the insert plate 84 drives the bag-supporting assembly 83 to extend into the bag opening. Subsequently, the thirteenth cylinder 92 pushes the second connecting rod 89 to move outward, and the two arm claws 88 are driven to extend outward simultaneously via the double rocker mechanism. The support plate 91 expands radially to a set width, forming a surface contact support with the inner wall of the bag opening. Then, the fourth motor 86 starts, and drives the straight arm 81 to rotate around its axis via the second rotating shaft 87, moving the opened packaging bag directly below the gate control assembly 67.

[0061] Two sets of seventh cylinders 65 synchronously drive the first crossbeam 63 downwards, causing the lower ends of the two sets of gates 76 to insert into the bag opening. Subsequently, the tenth cylinder 78 pushes the pressure plate 77 to rotate around the hinge point, pressing the bag opening against the gate 76, completing the initial fixation of the bag. The thirteenth cylinder 92 operates synchronously with the tenth cylinder 78, pulling the second connecting rod 89 inwards, causing the arm claw 88 to retract the support plate 91 to its minimum opening, disengaging the support plate 91 from the inner wall of the bag opening. The twelfth cylinder 85 retracts, pulling the first rotating shaft 82 to rotate, causing the insert plate 84 to pull the bag support assembly 83 out of the bag opening. The fourth motor 86 starts, driving the straight arm 81 back to its initial position via the second rotating shaft 87, awaiting the next work cycle. During the backswing of the straight arm 81, the eighth cylinders 68 on both sides synchronously push the second parallel connecting rod assembly 69 hinged to them, moving the support plate 70 above the bag opening. The ninth cylinder 75 pulls back the connecting seat 71, which drives the clamping arm 73 to rotate inward around the hinge point via the first connecting rod 74, clamping the corner of the bag opening and completing the secondary fixation of the packaging bag. Finally, the eleventh cylinders 79 on both sides simultaneously pull the gate 76 to open the compartment opening 64 and complete the filling operation.

[0062] During the filling process, the second motor 44 drives the synchronous belt 51 to rotate, which in turn drives the pallet 60 to move horizontally through the connecting block 55, moving the bag-supporting assembly 47 to both sides of the packaging bag being filled. After filling is completed, the eighth cylinder 68, the ninth cylinder 75, the tenth cylinder 78, and the eleventh cylinder 79 reset, the hopper opening 64 recloses, and the filled packaging bag falls onto the conveyor belt below (not shown in the figure). The sixth cylinder 61 drives the support arm 59 through the first parallel linkage assembly 56, the baffle 57 clamps the bag body from both sides, and the clamping plate 58 presses the bag opening from both sides. The second motor 44 drives the synchronous belt 51 in the opposite direction, and the return speed of the bag-supporting assembly 47 matches the conveying speed of the conveyor belt. In the initial state, the two sets of conveyor belt modules 48 are unfolded in a figure-eight shape, leaving space for the bag opening to be inserted. When the bag-supporting assembly 47 moves with the packaging bag to the conveyor belt module 48, the sixth cylinder 61 resets. The fifth cylinder 53 pushes the conveyor belt module 48 to rotate inward around its rotation axis, and the conveyor belt module 48 presses the two sides of the bag opening. The third motor 45 drives the conveyor belt on the conveyor belt module 48 to rotate through the in-line gearbox 50, flattening the bag opening, eliminating bag opening wrinkles, and preparing for the sealing process.
