[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 3 As shown, it is an IBC ton barrel 800 liner automatic valve tightening machine 10 according to an embodiment of the present invention, comprising: a support seat 100, a support plate 210, a rotating plate 220, a rotating driver 230, a vertical driver 240 and a valve tightening assembly 300;

[0028] The support seat 100 includes a base 110 and a longitudinal support 120 fixedly connected to the base 110, the longitudinal support 120 is perpendicular to the upper surface of the base 110, a first slide rail 121 is arranged on the longitudinal support 120, the first slide rail 121 is arranged along the vertical direction, the support plate 210 is slidably arranged on the first slide rail 121, the vertical driver 240 is arranged on the longitudinal support 120, the vertical driver 240 is drivingly connected to the support plate 210, and the vertical driver 240 is used to drive the support plate 210 to slide along the first slide rail 121 in the vertical direction;

[0029] The bottom end of the rotating plate 220 is rotatably connected to the bottom end of the supporting plate 210, the rotating driver 230 is disposed on the supporting plate 210, the rotating driver 230 is drivingly connected to the rotating plate 220, the rotating driver 230 is used to drive the rotating plate 220 to rotate on the supporting plate 210 relative to the supporting plate 210, and the valve twisting assembly 300 is disposed on a side of the rotating plate 220 facing away from the supporting plate 210.

[0030] In this embodiment, the valve twisting assembly 300 is used to grab or suck the valve cover 810 of the ton barrel 800. Specifically, when grabbing the valve cover 810, the rotary driver 230 drives the rotating plate 220 to rotate relative to the support plate 210, so that the rotating plate 220 rotates to be perpendicular to the support plate 210, and the rotating plate 220 is parallel to the horizontal direction, so that the valve twisting assembly 300 faces downward, toward the valve cover 810, and the vertical driver 240 drives the support plate 210 to move downward along the first slide rail 121, so that the valve twisting assembly 300 is close to the valve cover 810. After the valve twisting assembly 300 grabs the valve cover 810, the vertical driver 240 drives the support plate 210 along the first slide rail 121 again. 21 moves upward, when the rotating plate 220 gradually aligns with the barrel mouth of the ton barrel 800 during the upward process, the rotating driver 230 drives the rotating plate 220 to rotate relative to the support plate 210 again, until the side of the rotating plate 220 facing the support plate 210 is parallel to the side of the support plate 210 facing the rotating plate 220. At this time, the rotating plate 220 is parallel to the support plate 210, and the rotating plate 220 is parallel to the vertical direction. At this time, the valve assembly 300 is screwed toward the barrel mouth in the horizontal direction, and then the valve assembly 300 is screwed close to the barrel mouth, and the valve cover 810 is screwed at the barrel mouth, and then the valve assembly 300 is reset, and the above process is repeated to tighten the next valve cover 810.

[0031] The valve tightening machine in this embodiment has a simple structure and does not require a complex mechanical arm. By driving the rotating plate 220 to rotate, the valve tightening assembly 300 can be adjusted at different angles, thereby achieving the gripping and tightening of the valve cover 810 by the valve tightening assembly 300, which can effectively improve the tightening efficiency of the valve cover 810 and help reduce the production cost of the ton barrel 800. In addition, the valve tightening machine has a simple structure, which reduces the requirements for mechanical precision and can effectively improve the accuracy of gripping and tightening the valve cover 810.

[0032] In order to drive the rotating plate 220 so that the rotating plate 220 can rotate relative to the supporting plate 210, in one embodiment, Figures 3 to 5 As shown, the rotation driver 230 is a rotation drive cylinder, the cylinder body of the rotation drive cylinder is rotatably disposed on the top of the support plate 210 , and the piston rod of the rotation drive cylinder is rotatably connected to the top of the rotating plate 220 .

[0033] In this embodiment, the rotation drive cylinder drives the top end of the rotating plate 220 away from or close to the supporting plate 210 by extending and contracting the piston rod, so that the bottom end of the rotating plate 220 rotates relative to the bottom end of the supporting plate 210, thereby realizing the rotation drive of the rotating plate 220, and then driving the angle of the valve screw assembly 300 located on the rotating plate 220 to rotate. Figure 5As shown, when the piston rod of the rotating driving cylinder is extended, the top end of the rotating plate 220 is driven away from the supporting plate 210. At this time, the rotating plate 220 is rotated to be parallel to the horizontal direction, and the valve assembly 300 is turned downward. When the piston rod of the rotating driving cylinder is retracted, the top end of the rotating plate 220 is driven close to the supporting plate 210. At this time, the rotating plate 220 is rotated to be parallel to the vertical direction, and the valve assembly 300 is turned toward the horizontal direction.

[0034] In order to make the rotating plate 220 rotate more flexibly, in one embodiment, as Figures 3 to 5 As shown, a first rotating bracket 211 is provided at the top of the support plate 210, a second rotating bracket 221 is provided at the top of the rotating plate 220, and the height of the first rotating bracket 211 relative to the base 110 is greater than the height of the second rotating bracket 221 relative to the base 110, and a third rotating bracket 213 is provided on the side of the bottom end of the support plate 210 facing the rotating plate 220, the front end of the cylinder body of the rotating driving cylinder is rotatably connected to the first rotating bracket 211 through the first rotating shaft 212, the piston rod of the rotating driving cylinder is rotatably connected to the second rotating bracket 221 through the second rotating shaft 222, and the bottom end of the rotating plate 220 is rotatably connected to the third rotating bracket 213 through the third rotating shaft 214.

[0035] In this embodiment, by setting a first rotating bracket 211 at the top of the support plate 210 to support the movement of the cylinder body of the rotating driving cylinder, the cylinder body can adjust the angle with the movement of the rotating plate 220 during the driving process, making the driving more flexible. By setting a second rotating bracket 221 at the top of the rotating plate 220, the piston rod of the rotating driving cylinder can rotate freely relative to the rotating plate 220, thereby better driving the top of the rotating plate 220 to rotate. In addition, a third rotating bracket 213 is set at the bottom end of the support plate 210, so that the rotating plate 220 can rotate with the third rotating shaft 214 as the axis, and the rotating plate 220 can rotate at a larger angle and can be parallel to the surface of the support plate 210, so that the rotating plate 220 can be completely retracted.

[0036] In order to enable the rotation drive cylinder to drive the rotating plate 220 to rotate relative to the supporting plate 210, in one embodiment, as Figure 4 and Figure 5As shown, the axial direction of the piston rod of the rotation driving cylinder is inclined to the side of the support plate 210 facing the rotating plate 220. In this embodiment, the length direction of the cylinder body of the rotation driving cylinder is inclined to the side of the support plate 210 facing the rotating plate 220. In this embodiment, the piston rod of the rotation driving cylinder is inclined to the support plate 210, and the angle between the axial direction of the piston rod of the rotation driving cylinder and the side of the support plate 210 facing the rotating plate 220 is less than 90 degrees, so that when the piston rod of the cylinder of the rotation driving driver 230 is pushed out, the rotating plate 220 can be driven to rotate in a direction perpendicular to the support plate 210.

[0037] In one embodiment, if Figure 4 and Figure 5 As shown, the piston rod of the rotation driving cylinder gradually tilts downward from the end away from the rotating plate 220 to the end close to the rotating plate 220. In this embodiment, the cylinder body of the rotation driving cylinder gradually tilts downward from the end away from the supporting plate 210 to the end close to the supporting plate 210.

[0038] In this embodiment, Figure 5 As shown, since the piston rod of the rotating driving cylinder gradually tilts downward from far to near, the rear plug rod can extend downward when being pushed out, so that the top of the rotating plate 220 gradually rotates downward, so that the top of the rotating plate 220 rotates to be on the same horizontal plane as the bottom of the rotating plate 220, so that the rotating plate 220 rotates to a horizontal direction, perpendicular to the support plate 210, so that the valve assembly 300 on the rotating plate 220 can face the valve cover 810. Figure 4 As shown, when the piston rod contracts, the piston rod moves upward, driving the top of the rotating plate 220 to gradually rotate upward until it is parallel to the support plate 210, so that the rotating plate 220 rotates to be parallel to the vertical direction, and the rotating plate 220 is returned. In this embodiment, the piston rod of the rotation driving cylinder gradually tilts downward from the end away from the rotating plate 220 to the end close to the rotating plate 220, which can effectively improve the driving efficiency of the rotation of the rotating plate 220 and make the rotation drive of the rotating plate 220 more flexible.

[0039] In order to tighten the valve cover 810 on the barrel mouth, in one embodiment, as Figure 2 and Figure 3As shown, the valve twisting assembly 300 includes a driving motor 310, a reducer 320 and a valve twisting cylinder 330, the driving motor 310 is arranged on the rotating plate 220, the driving motor 310 is connected to the input end of the reducer 320, the reducer 320 is arranged on the side of the rotating plate 220 facing away from the support plate 210, and the output end of the reducer 320 is drivingly connected to the valve twisting cylinder 330, the valve twisting cylinder 330 is hollow, and the side walls of both sides of the valve twisting cylinder 330 away from the reducer 320 are provided with clamping grooves.

[0040] In this embodiment, the driving motor 310 is used to output power to drive the valve cylinder 330 to rotate, and the reducer 320 is used to reduce the rotation speed and amplify the torque. Through the reducer, the torque of the valve cylinder 330 can be effectively increased, so that the valve cylinder 330 can tighten the valve cover 810 at the barrel mouth. In addition, in this embodiment, the clamping groove provided at the open end of the valve cylinder 330 is used to allow the valve cover convex shaft and the valve cover twisting handle on the valve cover 810 to be embedded. When the valve cylinder 330 approaches the valve cover 810 under the drive of the support plate 210 sliding downward, the valve cover convex shaft and the valve cover twisting handle are respectively embedded in the clamping grooves of the side walls on both sides of the valve cylinder 330. Subsequently, when the valve cylinder 330 approaches the barrel mouth, the valve cylinder 330 rotates under the drive of the driving motor 310. The valve cylinder 330 drives the valve cover 810 to rotate through the cooperation of the clamping groove, the valve cover convex shaft and the valve cover twisting handle, which plays a good anti-slip effect.

[0041] In order to enable the valve cover 810 to be firmly grasped by the valve cylinder 330, in one embodiment, the automatic valve tightening machine 10 further includes a vacuum component (not shown), and a vacuum hole is provided at the bottom of the valve cylinder 330, and the vacuum component is connected to the vacuum hole. In this embodiment, the vacuum component is used to generate a vacuum, that is, to generate a negative pressure, so that the vacuum hole has an adsorption force through the negative pressure. When the valve cylinder 330 is sleeved on the valve cover 810, the vacuum component works, so that the vacuum hole generates a negative pressure, and the valve cover 810 is sucked into the valve cylinder 330, thereby achieving the grasping of the valve cover 810, and enabling the valve cover 810 to be grasped by the valve cylinder 330 more firmly.

[0042] To achieve the delivery of the valve cover 810, in one embodiment, as Figure 1As shown, the automatic valve tightening machine 10 further includes a valve cover conveyor belt 410, and the valve cover conveyor belt 410 is transmission-arranged below the rotating plate 220. In this embodiment, the valve tightening machine further includes a frame 400, and the valve cover conveyor belt 410 is transmission-arranged on the frame 400. A first conveying driver for driving the valve cover conveyor belt 410 is arranged on the frame 400, and the first conveying driver drives the valve cover conveyor belt 410 to transmit. The valve cover conveyor belt 410 is located below the rotating plate 220, and the valve cover conveyor belt 410 transmits through the rotating plate 220. In this embodiment, the conveying driver can be a stepper motor, which drives the valve cover conveyor belt 410 through the stepper motor, so that the valve cover conveyor belt 410 steps a certain distance at intervals, so that each time the valve cover conveyor belt 410 steps, a valve cover 810 is placed on the valve cover conveyor belt 410, so that the valve covers 810 are placed on the valve cover conveyor belt 410 at equal distances, so that each valve cover 810 passes under the rotating plate 220 in turn, and the valve cover 810 is grabbed by the valve screwing assembly 300 and screwed on the barrel mouth of the ton barrel 800. It is worth mentioning that the conveying driver can also be driven by other types of motors, which will not be described in detail in this embodiment.

[0043] In order to realize the delivery of the ton barrel 800, in one embodiment, please refer again to Figure 1 The automatic valve tightening machine 10 also includes a ton barrel conveyor belt 420, which is arranged parallel to the valve cover conveyor belt 410, and the ton barrel conveyor belt 420 is arranged on a side of the valve cover conveyor belt 410 away from the support seat 100.

[0044] In this embodiment, the ton barrel conveyor belt 420 is arranged on the frame 400, and the ton barrel conveyor belt 420 is used to convey the ton barrel 800. Specifically, a second conveying driver for driving the ton barrel conveyor belt 420 is arranged on the frame 400, and the second conveying driver drives the ton barrel conveyor belt 420 to transmit, and the ton barrel conveyor belt 420 transmits through the rotating plate 220. The valve cover conveyor belt 410 is located between the ton barrel conveyor belt 420 and the support seat 100, so that after the valve assembly 300 grabs the valve cover 810 on the valve cover conveyor belt 410, it moves toward the ton barrel conveyor belt 420, so that the valve cover 810 can be screwed on the barrel mouth of the ton barrel 800.

[0045] In order to enable the valve assembly 300 to be close to or away from the tote 800, in one embodiment, Figure 2As shown, the automatic valve tightening machine 10 also includes a fixed seat 510 and a horizontal driver 530. The fixed seat 510 is arranged on one side of the valve cover conveyor belt 410. The fixed seat 510 is provided with a second slide rail 520 perpendicular to the conveying direction of the valve cover conveyor belt 410. The base 110 is slidably arranged on the second slide rail 520. The horizontal driver 530 is arranged on the fixed seat 510, and the horizontal driver 530 is driven and connected to the base 110. The horizontal driver 530 is used to drive the base 110 to slide along the second slide rail 520.

[0046] In this embodiment, the fixing seat 510 is arranged on the frame 400, and the base 110 can slide along the second slide rail 520 to approach the ton barrel conveyor belt 420 or move away from the ton barrel conveyor belt 420. In this embodiment, the horizontal driver 530 is a horizontal driving cylinder, and the base 110 can drive the valve screwing assembly 300 to approach the ton barrel conveyor belt 420 under the drive of the horizontal driving cylinder. In this way, when the valve screwing assembly 300 grabs the valve cover 810, the driving base 110 of the horizontal driving cylinder approaches the ton barrel conveyor belt 420 and screws the valve cover 810 on the barrel mouth of the ton barrel 800.

[0047] The following is the specific implementation process:

[0048] Please combine Figures 1 to 5The valve cover 810 is transported on the valve cover conveyor belt 410 and transported to the bottom of the valve screw assembly 300. At the same time, the ton barrel conveyor belt 420 transports the ton barrel 800 to align with the valve screw assembly 300. The rotary driver 230 drives the rotary plate 220 to rotate to a horizontal direction, so that the opening of the valve screw cylinder 330 of the valve screw assembly 300 faces downward, and the vertical driver 240 drives the support plate 210 to move downward, driving the valve screw cylinder 330 to move downward and sleeved on the valve cover 810. The valve screw cylinder 330 grabs the valve cover 810. Subsequently, the vertical driver 240 drives the support plate 210 to move upward, driving the valve screw cylinder 330 to move upward, and the rotary driver 230 drives the rotary plate 220 to rotate to a vertical direction, so that the opening of the valve screw cylinder 330 of the valve screw assembly 300 faces the ton barrel 800, and the vertical driver 240 drives the support plate 210 to move downward again, so that the valve screw cylinder 330 is aligned. At the mouth of the ton barrel 800, the horizontal driver 530 drives the base 110 to slide on the second slide rail 520, so that the valve cylinder 330 is close to the mouth of the ton barrel 800, and the driving motor 310 drives the valve cylinder 330 to rotate, and the valve cover 810 on the valve cylinder 330 is rotated and screwed on the mouth of the barrel. Then, the horizontal driver 530 drives the base 110 away from the ton barrel conveyor belt 420, so that the valve cylinder 330 is separated from the valve cover 810 that has been screwed on the mouth of the barrel, and the valve cover conveyor belt 410 steps a distance, so that the next valve cover 810 is aligned with the valve assembly 300 and is located below the valve assembly 300. The above process is repeated to screw each valve cover 810 on the ton barrel 800 in turn.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
