Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging machines, in particular to a special bag-grabbing device for automatic packaging machines. Background Art

[0002] The bag-grabbing device is an important part of an automatic packaging machine. Its main function is to automatically grab and position the packaging bag for subsequent packaging operations such as sealing. Under the current trend of intelligentization and automation in the packaging machine industry, the technology of packaging machines needs to be continuously updated. There are various types of packaging bags involved in automatic packaging machines. During the automatic sealing process, the bag mouth of the packaging bag is prone to collapse, resulting in the bag mouth of the packaging bag not being able to smoothly enter the sealing mechanism, and manual intervention is required to adjust the bag mouth of the packaging bag. Especially for packaging bags with softer materials, the bag mouth of the packaging bag needs to be manually adjusted at all times, increasing the labor intensity of workers and reducing work efficiency. At the same time, after the packaging bag is filled with materials, the packaging bag has a certain weight. When the existing bag-grabbing device grabs the packaging bag and moves, the packaging bag is very easy to slide off. Therefore, a special bag-grabbing device for automatic packaging machines is needed to meet the market demand. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a special bag-grabbing device for an automatic packaging machine with good grasping effect and capable of adapting to the sealing of various packaging bags.

[0004] To achieve the above technical purpose, the utility model proposes the following technical solution: A special bag-grabbing device for an automatic packaging machine, including an automatic packaging machine body, a bottom plate slidably arranged on the automatic packaging machine body. The bottom plate is provided with a left clamp and a right clamp. The left clamp and the right clamp are symmetrically arranged. The left clamp and the right clamp both include a mounting plate, a main grasping plate, a secondary grasping plate, and a cylinder 1. The main grasping plate and the secondary grasping plate are both arranged on one side of the mounting plate, and the main grasping plate and the secondary grasping plate are hinged. The cylinder 1 is arranged on the mounting plate and the cylinder 1 drives the secondary grasping plate to open and close. Both the main grasping plate and the secondary grasping plate are provided with an air inlet pipeline. A plurality of air outlet ports respectively communicated with the air inlet pipeline are opened on the top side surfaces of the main grasping plate and the secondary grasping plate. An air pipe joint is installed at the air inlet of the air inlet pipeline.

[0005] Further, inclined ripple grooves are provided on the inner walls of both the main grasping plate and the secondary grasping plate.

[0006] Further, the inclined ripple grooves are arranged in a downward inclination, and the inclined ripple grooves on the main grasping plate and the inclined ripple grooves on the secondary grasping plate fit each other.

[0007] Further, one end of the main grasping plate is provided with a hinge seat. One end of the hinge seat is arranged on the mounting plate. One end of the secondary grasping plate is provided with a connecting plate of a Y-shaped structure. One end of the connecting plate is connected to the hinge seat through a pin shaft, and the other end of the connecting plate is hinged to the piston rod of the cylinder 1.

[0008] Furthermore, the mounting plates are all slidably mounted on the bottom plate. Two cylinders II are provided in the middle of the bottom plate, and the two cylinders II respectively drive the left clamp and the right clamp to slide.

[0009] Compared with the prior art, the beneficial effects produced by the present utility model are as follows: The structure of the present utility model is novel, ingeniously conceived, and simple and convenient to operate. Compared with the prior art, it has the following advantages: The present utility model increases the friction force through the obliquely downward inclined ripple grooves where the main clamping plate and the auxiliary clamping plate are in contact, and further tightens the bag mouth to stabilize the bag from slipping; through structures such as the air inlet pipeline and the air outlet, continuous upward blowing can ensure that the packaging bag with a softer material can keep the bag mouth upright, ensuring that the bag can be smoothly fed into the sewing bag mechanism without manual intervention, thereby improving the work efficiency.

Specific Embodiments

[0017] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the drawings. However, the present utility model is not limited to these embodiments. At the same time, it should be noted that the present utility model is applicable not limited to the intermediate link of moving the bag to the sealing mechanism when the feeding of the packaging bag is completed.

[0018] Such as Figures 1-5As shown in the figure, the utility model provides a bag-grabbing device special for an automatic packaging machine, which comprises an automatic packaging machine body 1. The automatic packaging machine body 1 includes a filling mechanism 16 and a sealing mechanism 17. It further includes a bottom plate 2 slidably arranged on the automatic packaging machine body 1. A left clamp 3 and a right clamp 4 are arranged on the bottom plate 2. The left clamp 3 and the right clamp 4 are symmetrically arranged. Both the left clamp 3 and the right clamp 4 include a mounting plate 5, a main gripping plate 6, a secondary gripping plate 7 and a cylinder 1 8. The main gripping plate 6 and the secondary gripping plate 7 are both arranged on one side of the mounting 5, and the main gripping plate 6 and the secondary gripping plate 7 are hinged. The cylinder 1 8 is arranged on the mounting plate 5 and the cylinder 1 8 drives the secondary gripping plate 7 to open and close. An air inlet pipeline 9 is arranged on both the main gripping plate 6 and the secondary gripping plate 7. A plurality of air outlet holes 10 communicated with the air inlet pipeline 9 are respectively opened on the top sides of the main gripping plate 6 and the secondary gripping plate 7. An air pipe joint 11 is installed at the air inlet of the air inlet pipeline.

[0019] As Figures 1-5 shown, the main gripping plate 6 is in a fixed state relative to the secondary gripping plate 7. The secondary gripping plate 7 realizes the grasping and opening of the packaging bag through the telescopic movement of the cylinder 1 8. The air pipe joint 11 is connected with an air delivery mechanism. Gas is delivered to the air inlet pipeline 9 through the air pipe joint 11, and the gas on the air inlet pipeline 9 is discharged from the air outlet holes 10. Specifically, the left clamp 3 and the right clamp 4 respectively clamp both sides of the packaging bag. Gas is continuously delivered to the air inlet pipeline 9 through the air delivery mechanism. The gas continuously blows upward, which can ensure that the packaging bag with a relatively soft material can keep the bag mouth upright, ensuring that the packaging bag can be smoothly sent into the sealing mechanism 17 for sealing without manual intervention.

[0020] Ripple grooves 12 with inclined lines are arranged on the inner walls of both the main gripping plate 6 and the secondary gripping plate 7.

[0021] As Figure 4 and 5 shown, when the main gripping plate 6 and the secondary gripping plate 7 clamp the packaging bag, the ripple grooves 12 with inclined lines can increase the friction force between the main gripping plate 6 and the secondary gripping plate 7 and the packaging bag, preventing the packaging bag from sliding down.

[0022] The ripple grooves 12 with inclined lines are arranged in a downward inclined manner, and the ripple grooves 12 with inclined lines on the main gripping plate 6 and the ripple grooves 12 with inclined lines on the secondary gripping plate 7 fit with each other.

[0023] As Figure 3 shown, under the action of the gravity of the material, the packaging bag slides downward. If the packaging bag slides downward, the downward force is guided by the ripple grooves 12 with inclined lines into a tendency of the bag mouth to move obliquely downward to both sides, further tightening the bag mouth and increasing the friction force to stabilize the packaging bag from sliding down.

[0024] One end of the main grab plate 6 is provided with a hinge seat 13, one end of the hinge seat 13 is installed on the mounting plate 5 by bolts, one end of the auxiliary grab plate 7 is provided with a Y-shaped connecting plate 14, one end of the connecting plate 14 is connected to the hinge seat 13 by a pin shaft, and the other end of the connecting plate 14 is hinged to the piston rod of the cylinder 8.

[0025] like Figure 4 and Figure 5 As shown, the main grab plate 6 and the hinge seat 13 are an integrally formed structure, and the auxiliary grab plate 7 and the connecting plate 14 are an integrally formed structure. The connecting plate 14 is pulled to control the opening and closing of the auxiliary grab plate 7 by extending and retracting the cylinder 8.

[0026] The mounting plates 5 are all slidably mounted on the bottom plate 2. Two cylinders 15 are provided in the middle of the bottom plate 2. The two cylinders 15 drive the left clamp 3 and the right clamp 4 to slide respectively.

[0027] like Figure 2 As shown, the spacing between the left clamp 3 and the right clamp 4 is controlled by the cylinder 2 15 to flatten the mouth of the packaging bag so as to achieve automatic sealing of the packaging bag without manual intervention. It is also suitable for grasping packaging bags of various sizes.

[0028] Principle of use: under the action of the filling mechanism 16, the material is poured into the packaging bag, and the left clamp 3 and the right clamp 4 clamp the two sides of the packaging bag respectively. Specifically, the piston rod of the cylinder 8 extends, and the auxiliary gripping plate 7 moves toward the main gripping plate 6 until the oblique corrugated groove 12 on the main gripping plate 6 is embedded with the oblique corrugated groove 12 on the auxiliary gripping plate 7, so as to stabilize the packaging bag from sliding down. After grabbing the packaging bag, gas is injected into the air inlet pipe 9 through the air pipe joint 11, and the gas is discharged from the air outlet 10. The gas is continuously blown upwards, which can ensure that the packaging bag with a softer material can keep the bag mouth upright, and ensure that the packaging bag can be smoothly delivered to the packaging mechanism 17 for sealing without human intervention. After years of market exploration, the bag grabbing device can meet the automatic packaging and sealing of 98% of the bags in the market.

[0029] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
