Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capping machines, in particular to an automatic capping machine. Background Art
[0002] In modern production, automated capping machines are key equipment on the packaging production line, and their performance and efficiency directly affect the packaging quality and production efficiency of the products. Traditional automated capping machines typically use multiple motors or drive devices to control the steps of picking up, conveying, capping, and resetting. This not only leads to complex equipment structure and high maintenance costs, but also increases energy consumption. In addition, during the capping process, various factors (such as differences in bottle cap material, size, and uneven capping force) may cause the capping quality to substandard. Traditional capping machines often lack corresponding detection methods, making it difficult to detect and handle substandard products in a timely manner, thus affecting the overall quality of the product. Utility Model Content
[0003] In view of the deficiencies in the prior art, the present invention provides an automatic capping machine, which has the advantages of automatic capping, clever structure and low cost, and solves some problems raised in the background technology.

[0005] Furthermore, a pickup tray is fixedly mounted on the outer side of the transmission shaft near the machine, the right side of the pickup tray is on the upper side of the conveying device, and a limiting rail is fixedly installed on the upper end of the machine near the outer circle of the pickup tray. The upper end of the machine is consistent in height with the conveyor belt of the conveying device, ensuring the rationality of the structural design.
[0006] Furthermore, a slave bevel gear is fixedly sleeved on the outer side of the rotating shaft near the upper side, and a rotatable differential is fixedly installed on the vertical frame between the slave bevel gear and the main bevel gear. The main bevel gear is connected to the slave bevel gear through the differential, that is, while the pickup disk rotates relatively slowly, the pressing operation of the pressing shaft will be faster and faster under the influence of the differential, thereby avoiding greater wear on the pickup disk.
[0007] Furthermore, the right end of the stand is fixedly connected to a guide plate at the lower side of the fixed block, the lower end of the pressure cover shaft passes through the guide plate, and the pressure cover shaft is slidably sleeved with two groups of symmetrical spring seats on the outer side of the thin rod at the lower end. A return spring is provided between the two groups of spring seats on the outer side of the pressure cover shaft, and the spring seat on the lower side is fixedly connected to the guide plate. The guide plate can not only fix the spring seat on the lower side to ensure the rebound effect, but also improve the structural stability of the pressure cover shaft.
[0008] Furthermore, a height-adjustable laser sensor is fixedly installed at the rear end of the stand, and the laser beam of the laser sensor is on the rotating track of the pickup tray, that is, the bottle body will definitely undergo laser detection during the rotation process, but the laser will only be blocked when the bottle cap does not meet the standards.
[0009] Furthermore, a fixing bracket is fixedly installed at the upper end of the conveying device near the rear side of the pickup plate, and an electric push rod is fixedly installed at the middle of the lower end of the fixing bracket.

The electric push rod is signal-connected to the laser sensor.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. This automatic capping machine device uses an ingenious transmission system to achieve the operation of driving the pickup disk to rotate and pick up the items and the capping and reset operations of the capping shaft through a stepper motor. This design not only simplifies the equipment structure and makes it more compact, but also significantly reduces the use cost and energy consumption.
[0012] 2. This automatic capping machine is also equipped with a laser sensor. When the pickup tray continues to drive the capped bottle to rotate, the laser sensor will emit a scanning laser and detect whether there is an obstacle blocking the laser and the target point. Once an obstacle blocks the bottle, the laser sensor will immediately detect the change and feedback information, indicating that the capping is unqualified. It will automatically control and open the electric push rod, so that its output end drives the retaining rail to descend to the inside of the conveying device, so that the unqualified bottle can re-participate in the capping operation under the rotation of the pickup tray, thereby avoiding the situation of substandard capping and ensuring product quality. This design not only improves the product qualification rate, but also reduces the economic losses caused by unqualified products, and has significant social benefits.

[0020] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0021] See also Figures 1-6 , an automatic capping machine, including a conveying device 1, a machine table 2 is set at the left end of the conveying device 1, a transmission shaft 3 is rotatably installed on the machine table 2, and a main bevel gear 6 is fixedly sleeved on the transmission shaft 3 near the upper side. A stand 7 is fixedly installed on the upper end of the machine table 2 at the middle of the left side of the pickup tray 4, and a rotating shaft 9 is rotatably installed on the stand 7 near the middle of the left side. A fixed block 12 is fixedly connected to the middle of the right end of the stand 7, and a capping shaft 11 is passed through the interior of the fixed block 12. The left and right ends of the rotating shaft 9 are fixedly connected to limit blocks 13 near the lower side. The interior of the capping shaft 11 is provided with a slide groove 14, and the limit block 13 is slidably connected to the interior of the slide groove 14. The left and right ends of the capping shaft 11 are fixedly connected with guide blocks 15 near the middle. The left and right inner walls of the fixed block 12 are provided with inclined grooves 16, and the guide blocks 15 are slidably connected to the interior of the inclined grooves 16. When the device is in use, the bottle body to be capped is transported to the pickup tray 4 through the conveying device 1, and the stepping motor in the machine 2 is driven to rotate the transmission shaft 3. The rotation of the transmission shaft 3 can drive the pickup tray 4 to rotate, so that the bottle is taken out by the rotation of the pickup tray 4. The main bevel gear 6 is driven by the main bevel gear 6, and the differential gear 8 is driven by the main bevel gear 6 to rotate. The rotation of the bevel gear 10 drives the rotating shaft 9 to rotate. Due to the limiting effect of the limit block 13 and the slide groove 14, the rotation of the rotating shaft 9 can drive the gland shaft 11 to rotate. When the gland shaft 11 rotates and drives the guide block 15 to rotate, the gland shaft 11 will move downward while rotating due to the downward guiding effect of the inclined groove 16. The bottle body is moved, and the return spring 19 is compressed at this time. When the lower end of the capping shaft 11 drops to a certain height, the bottle body is driven to the lower side of the capping shaft 11 by the removal disk 4. Under the speed-increasing effect of the differential 8, the capping shaft 11 will drop quickly to perform a hammering action, thereby performing a capping operation on the cap placed at the bottle mouth by a bottle cap placing device such as an automatic capping machine. The device can realize the rotation and removal of the removal disk 4 and the capping and resetting operations of the capping shaft 11 by a stepping motor. The structure is ingenious and compact, which reduces the use cost and energy consumption.
[0022] See also Figure 1-Figure 2 The outer side of the transmission shaft 3 is fixedly sleeved with a pickup tray 4 near the machine 2. The right part of the pickup tray 4 is on the upper side of the conveying device 1. The upper end of the machine 2 is fixedly installed with a limiting rail 5 near the outer circle of the pickup tray 4. The upper end of the machine 2 is at the same height as the conveyor belt of the conveying device 1, which ensures that the bottle body will not cause any obstruction when moving from the conveying device 1 to the machine 2. The bottle body can be limited by the limiting rail 5 so that it can move synchronously driven by the pickup tray 4.
[0023] See also Figure 2-Figure 4The outer side of the rotating shaft 9 is fixedly sleeved with a slave bevel gear 10 near the upper side. A rotatable differential 8 is fixedly installed on the frame 7 between the slave bevel gear 10 and the main bevel gear 6. The main bevel gear 6 is connected to the slave bevel gear 10 through the differential 8. The right end of the frame 7 is fixedly connected with a guide plate 17 at the lower side of the fixed block 12. The lower end of the gland shaft 11 passes through the guide plate 17. The gland shaft 11 is slidably sleeved with two sets of symmetrical elastic springs on the outer side of the thin rod at the lower end. Spring seat 18, a return spring 19 is provided on the outside of the capping shaft 11 between the two sets of spring seats 18, and the lower spring seat 18 is fixedly connected to the guide plate 17. When the capping shaft 11 descends, the rotating shaft 9 and the limit block 13 will slide toward the upper end of the slide groove 14. At the same time, the picking plate 4 will pause slightly under the control of the stepper motor, so that the capping shaft 11 has time to reset under the rebound action of the return spring 19, thereby preparing for the next set of capping operations.
[0024] See also Figure 1-Figure 2 The rear end of the stand 7 is fixedly equipped with a height-adjustable laser sensor 20, and the laser beam of the laser sensor 20 is on the rotating track of the pickup tray 4. The upper end of the conveyor device 1 is fixedly equipped with a fixing frame 21 near the rear side of the pickup tray 4, and the middle of the lower end of the fixing frame 21 is fixedly equipped with an electric push rod 22. The lower output end of the electric push rod 22 is fixedly connected with a blocking rail 23, which fits with the limit rail 5 and is stuck in the interior of the conveyor device 1. When the pickup tray 4 continues to drive the bottle body after capping to rotate, when an obstacle appears between the scanning laser emitted by the laser sensor 20 and the target point and is blocked, the laser sensor 20 will detect this change and feedback information, indicating that the capping is unqualified, thereby controlling and opening the electric push rod 22 so that its output end drives the blocking rail 23 to descend to the interior of the conveyor device 1, blocking the bottle body with unqualified capping so that it can re-participate in the capping operation under the rotation of the pickup tray 4, thereby avoiding the situation of substandard capping, ensuring the quality of the product, and having a simple and practical structure.
[0025] When the bottle body to be capped is transported to the picking plate 4 by the conveying device 1, the stepping motor in the machine table 2 is turned on to drive the transmission shaft 3 to rotate. The rotation of the transmission shaft 3 can drive the picking plate 4 to rotate, so that the bottle body is brought into the groove by the rotation of the picking plate 4 and then rotated to the capping shaft 11. In this process, the rotation of the transmission shaft 3 can also drive the main bevel gear 6 to rotate, and the rotation of the main bevel gear 6 can drive the differential gear 8 to rotate the slave bevel gear 10, and the rotation of the slave bevel gear 10 drives the rotating shaft 9 to rotate. Due to the limiting effect of the limit block 13 and the slide groove 14, the rotation of the rotating shaft 9 can drive the capping shaft 11 to rotate. When the capping shaft 11 rotates and drives the guide block 15 to rotate, due to the downward guiding effect of the inclined groove 16, the capping shaft 11 will rotate and move downward. At this time, the reset spring 19 is compressed. When the lower end of the capping shaft 11 drops to a certain height, the bottle body is driven by the picking plate 4 to the lower side of the capping shaft 11 at the differential gear 13. Under the accelerating action of the speed reducer 8, the capping shaft 11 will quickly descend and perform a hammering action, thereby performing a capping operation on the cap placed at the bottle mouth by the bottle cap placing device such as the automatic capping machine. In this process, when the capping shaft 11 descends, the rotating shaft 9 and the limit block 13 will slide to the upper end of the slide groove 14. At the same time, the picking plate 4 will pause slightly under the control of the stepper motor, so that the capping shaft 11 has time to reset under the rebound action of the reset spring 19, thereby preparing for the next set of capping operations. In addition, when the picking plate 4 continues to drive the bottle body after capping to rotate, when an obstacle appears between the scanning laser emitted by the laser sensor 20 and the target point and is blocked, the laser sensor 20 will detect this change and feedback information, indicating that the capping is unqualified, thereby controlling and opening the electric push rod 22 so that its output end drives the blocking rail 23 to descend to the inside of the conveying device 1, blocking the bottle body with unqualified capping so that it can re-participate in the capping operation under the rotation of the picking plate 4.
