Description

Technical Field

[0001] The embodiments of this utility model relate to the field of packaging technology, specifically to an automatic bolt packaging machine. Background Technology

[0002] Bolts are fasteners widely used in the production and processing of parts. Because they are manufactured in mass production, bolts are usually packaged by conveying them at a certain speed and then weighing them for a rough count.

[0003] Patent document CN109292158A discloses an automatic bolt packaging machine, including a storage hopper, a chain conveyor, a control box, a guide plate, a feeding unit, a detection unit, a dispensing unit, and a sealing machine. The feeding unit includes a first cylinder, a first telescopic rod, a first fixed seat, a second fixed seat, a baffle, a feeding channel, and a vibrating plate. The guide plate is located on the vibrating plate. The detection unit includes a second cylinder, a second telescopic rod, a third fixed seat, a fourth fixed seat, a weighing hopper, and a first guiding channel. The dispensing unit includes a second guiding channel, a fixed plate, a third guiding channel, and a first material box.

[0004] The aforementioned application document describes a method where bolts are fed to a feeding channel via a vibratory feeder. A first cylinder controls the retraction of a first telescopic rod, which in turn drives a second fixed seat to rotate a baffle clockwise around a second rotating shaft. This opens the feeding channel, allowing a certain amount of bolts to fall into the weighing hopper of the detection unit. The overall conveying process is relatively sealed, which is not conducive to subsequent sorting and packaging and therefore needs improvement. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides an automatic bolt packaging machine, which solves the problem that the overall conveying in the prior art is relatively sealed, which is not conducive to subsequent sorting and packaging.

[0006] According to one aspect, at least one embodiment of the present invention provides an automatic bolt packaging machine, comprising: a base and a conveyor belt; a placement box and a machine body are fixedly connected to the top of the base; an opening is provided on the side of the placement box; a feeding plate is fixedly connected to the side of the placement box; a driving roller and a driven roller are rotatably connected to the inner side of the machine body; the driven roller is drivenly connected to the driving roller via the conveyor belt; a conveyor motor is fixedly installed at the front end of the machine body; a sorting and packaging mechanism is provided on the top of the base; and an intermittent feeding mechanism is provided at the front end of the placement box; the sorting and packaging mechanism includes a placement tray and a guide. The tray and packaging box are fixedly connected to the top of the base. The packaging box is placed on the top of the base. A baffle is fixedly connected to the top of the tray. A feeding port is opened on the top of the tray. A rotating shaft is rotatably connected inside the tray. A rotating plate is fixedly connected to the surface of the rotating shaft. A rotating block is fixedly connected to the end of the rotating shaft away from the tray. A torsion spring is fixedly connected to the end of the rotating block near the tray. A rotating rod is rotatably connected through the top of the tray. A scraper is fixedly connected to the surface of the rotating rod. A rotating motor is fixedly installed at the bottom of the tray.

[0007] For example, in at least one embodiment of the present invention, an automatic bolt packaging machine is provided, which further includes: a feeding plate is fixedly connected to the surface of the conveyor belt, and the end of the unloading plate away from the placement box is close to the conveyor belt. The movement of the conveyor belt drives the feeding plate to move and transport the bolts upward. The bolts falling from the unloading plate will fall onto the feeding plate.

[0008] The output shaft of the conveyor motor is fixedly connected to the drive roller. The diameters of the drive roller and the driven roller are equal. When the conveyor motor is started, it will drive the drive roller to rotate through its output shaft. The rotation of the drive roller, in conjunction with the driven roller, drives the conveyor belt to move.

[0009] The guide plate and the packaging box are both set in two sets, and the two sets of guide plates and the packaging box are symmetrically arranged in a rotating manner. The bolts of different weights are transported to their respective packaging boxes through the two sets of guide plates.

[0010] The top of one set of guide plates is close to the bottom of the rotating plate, and the top of the other set of guide plates is close to the bottom of the discharge port. Bolts falling from the rotating plate and the discharge port will fall onto the two sets of guide plates respectively.

[0011] The output shaft of the rotating motor is fixedly connected to the rotating rod. The bottom of the scraper is close to the top of the placement tray. When the rotating motor is turned on, its output shaft will drive the rotating rod to rotate. When the scraper rotates, it will drive the bolts inside the placement tray to move.

[0012] The rotating block is initially set horizontally. The end of the torsion spring away from the rotating block is fixedly connected to the side of the placement plate. When the rotating block is affected by a heavy bolt, it will deflect and the torsion spring will deform.

[0013] According to another aspect, at least one embodiment of the present invention also provides an intermittent feeding mechanism, including an eccentric ring and a pneumatic chamber. The eccentric ring is fixedly connected to the surface of the output shaft of the conveying motor. The pneumatic chamber passes through and is fixedly connected to the front end of the placement box. An air bladder is provided at one end of the pneumatic chamber, and a piston rod is slidably connected to the piston inside the other end of the pneumatic chamber. A baffle is fixedly connected to the end of the piston rod away from the pneumatic chamber.

[0014] For example, in at least one embodiment of the present invention, an automatic bolt packaging machine is provided, which further includes: the width of the baffle is greater than the width of the opening, and the baffle is close to the opening, and the opening will be closed when the baffle moves to the rear end.

[0015] The end of the airbag furthest from the pressure chamber is close to the eccentric ring, and the airbag is initially in an inflated state. When the eccentric ring rotates with the output shaft of the conveyor motor, it will repeatedly squeeze the airbag. When the airbag is squeezed, the air pressure inside it will enter the pressure chamber and push the piston rod to move to the rear end.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. This utility model incorporates a sorting and packaging mechanism. When the conveyor motor is turned on to transport the bolts to the top and into the placement tray, the rotating motor can be activated to drive the rotating rod to rotate. The rotating rod then drives the scraper to rotate, which in turn moves the bolts in the placement tray. Larger bolts will be deflected by gravity and fall onto the guide plate at their bottom, while lighter bolts will fall from the discharge port and finally slide into their respective packaging boxes, thus achieving the effect of automatic sorting and packaging.

[0018] 2. In this utility model, by setting an intermittent feeding mechanism, when the conveyor motor is turned on to feed the bolts, the baffle is driven to move repeatedly to the rear end through the cooperation of components such as the eccentric ring, air bag, and air pressure chamber. The opening is closed intermittently by the repeated movement of the baffle to the rear end, preventing too many bolts from being fed into the opening at one time. Attached Figure Description

[0032] like Figures 1-5 The diagram illustrates an automatic bolt packaging machine according to an embodiment of the present invention, comprising: a base 1 and a conveyor belt 9; a placement box 2 and a machine body 5 are fixedly connected to the top of the base 1; an opening 3 is provided on the side of the placement box 2; a feeding plate 4 is fixedly connected to the side of the placement box 2; a driving roller 6 and a driven roller 7 are rotatably connected to the inner side of the machine body 5; the driven roller 7 is driven by the driving roller 6 via the conveyor belt 9; a conveyor motor 8 is fixedly installed at the front end of the machine body 5; a sorting and packaging mechanism 11 is provided on the top of the base 1; and an intermittent feeding mechanism 12 is provided at the front end of the placement box 2; the sorting and packaging mechanism 11 includes a placement tray 111, a guide plate 112, and a packaging box 113; the placement tray 111 and the guide plate 112... All are fixedly connected to the top of the base 1. The packaging box 113 is placed on the top of the base 1. The top of the placement tray 111 is fixedly connected to the baffle 114. The top of the placement tray 111 has a discharge port 115. The interior of the placement tray 111 is rotatably connected to the rotating shaft 116. The surface of the rotating shaft 116 is fixedly connected to the rotating plate 119. The end of the rotating shaft 116 away from the placement tray 111 is fixedly connected to the rotating block 117. The end of the rotating block 117 close to the placement tray 111 is fixedly connected to the torsion spring 118. The top of the placement tray 111 is rotatably connected to the rotating rod 1110. The surface of the rotating rod 1110 is fixedly connected to the scraper 1111. The bottom of the placement tray 111 is fixedly installed with the rotating motor 1112.

[0033] In some examples, the surface of the conveyor belt 9 is fixedly connected to the upper plate 10, and the end of the lower plate 4 away from the placement box 2 is close to the conveyor belt 9. The movement of the conveyor belt 9 drives the upper plate 10 to move and transport the bolts upward. The bolts falling from the lower plate 4 will fall onto the upper plate 10.

[0034] The output shaft of the conveyor motor 8 is fixedly connected to the drive roller 6. The diameters of the drive roller 6 and the driven roller 7 are equal. When the conveyor motor 8 is started, it will drive the drive roller 6 to rotate through its output shaft. The rotation of the drive roller 6, in conjunction with the driven roller 7, drives the conveyor belt 9 to move.

[0035] Both the guide plate 112 and the packaging box 113 are set in two sets, and the two sets of guide plates 112 and the packaging box 113 are symmetrically arranged with a rotating rod 1110. Bolts of different weights are transported to their respective packaging boxes 113 through the two sets of guide plates 112.

[0036] The top of one set of guide plates 112 is close to the bottom of the rotating plate 119, and the top of the other set of guide plates 112 is close to the bottom of the discharge port 115. Bolts falling from the rotating plate 119 and the discharge port 115 will fall onto the two sets of guide plates 112 respectively.

[0037] The output shaft of the rotating motor 1112 is fixedly connected to the rotating rod 1110. The bottom of the scraper 1111 is close to the top of the placement tray 111. When the rotating motor 1112 is turned on, its output shaft will drive the rotating rod 1110 to rotate. When the scraper 1111 rotates, it will drive the bolts inside the placement tray 111 to move.

[0038] The rotating block 117 is initially set horizontally. The end of the torsion spring 118 away from the rotating block 117 is fixedly connected to the side of the placement plate 111. When the rotating block 117 is affected by a heavy bolt, it will deflect and the torsion spring 118 will deform.

[0039] For example, such as Figures 1-5As shown, when a large batch of bolts needs to be sorted and packaged, the bolts are placed into the placement box 2. The bolts will fall from the side opening 3 of the placement box 2 through the feeding plate 4 onto the feeding plate 10 on the conveyor belt 9. Turning on the conveyor motor 8 will drive the drive roller 6 to rotate through its output shaft. The rotation of the drive roller 6 will work with the driven roller 7 to move the conveyor belt 9. The movement of the conveyor belt 9 will move the feeding plate 10, and the movement of the feeding plate 10 will move the bolts upward. Subsequently, the bolts will fall from the feeding plate 10 onto the placement tray 111. Then, the rotation motor 1112 can be turned on. The rotation motor 1112 will drive the rotating rod 1110 to rotate. The rotation of the rotating rod 1110 will... The rotating scraper 1111 moves the bolts inside the placement tray 111. When the bolts move onto the rotating plate 119, if the bolts are large and heavy, gravity will cause the rotating plate 119 to rotate, and the torsion spring 118 will deform. At this time, the bolts will fall onto the guide plate 112 below the rotating plate 119 and slide into the packaging box 113. Then the torsion spring 118 will rebound and cause the rotating plate 119 to return to its original position. If the bolts are small and light, they will fall from the discharge port 115 and slide from the guide plate 112 below the discharge port 115 into the packaging box 113 at the other end, thus achieving the effect of sorting and packaging.

[0040] like Figures 1-5 As shown, it illustrates an intermittent feeding mechanism 12 in another embodiment of the present invention, including an eccentric ring 121 and a pressure chamber 122. The eccentric ring 121 is fixedly connected to the surface of the output shaft of the conveying motor 8. The pressure chamber 122 passes through and is fixedly connected to the front end of the placement box 2. An air bladder 123 is provided at one end of the pressure chamber 122. A piston rod 124 is slidably connected to the piston inside the other end of the pressure chamber 122. A baffle 125 is fixedly connected to the end of the piston rod 124 away from the pressure chamber 122.

[0041] In some examples, the width of the baffle 125 is greater than the width of the opening 3, and the baffle 125 is close to the opening 3. When the baffle 125 moves to the rear end, it will close the opening 3.

[0042] The end of the airbag 123 away from the pressure chamber 122 is close to the eccentric ring 121, and the airbag 123 is initially in an inflated state. When the eccentric ring 121 rotates with the output shaft of the conveyor motor 8, it will repeatedly squeeze the airbag 123. When the airbag 123 is squeezed, the air pressure inside it will enter the pressure chamber 122 and push the piston rod 124 to move to the rear end.

[0043] For example, such as Figures 1-5As shown, when the conveyor motor 8 is turned on and drives the active roller 6 to rotate through its output shaft, the eccentric ring 121 will repeatedly squeeze the airbag 123 as it rotates with the output shaft of the conveyor motor 8. When the airbag 123 is squeezed, the air pressure inside it will enter the air pressure chamber 122 and push the piston rod 124 to move to the rear end. The piston rod 124 moving to the rear end will drive the baffle 125 to move to the rear end. When the eccentric ring 121 leaves the airbag 123, the airbag 123 will rebound. The air pressure inside the air pressure chamber 122 will drive the piston rod 124 and the baffle 125 to move to the front end to restore their original position. The baffle 125 will intermittently close the opening 3 by repeatedly moving to the rear end to prevent too many bolts from being fed into the opening 3 at once.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
