Description

Technical Field

[0001] The utility model relates to the technical field of coding devices, in particular to a coding device for plastic powder packaging bags. Background Art

[0002] The coding machine is a non-contact inkjet marking system controlled by a single chip. It controls the internal gear pump or supplies compressed gas from the outside of the machine to apply a certain pressure to the ink in the system, so that the ink is ejected through a nozzle with an aperture of tens of microns and hits different positions on the surface of the product to form various required texts, patterns and other markings. Using a coding machine to print on packaging bags can print dates, QR codes and instructions on packaging bags, but the coding machines in the prior art still have defects.

[0003] In the prior art, when coding a packaging bag using a coding device, a fixed method is used, wherein the packaging bag is transported by a conveyor, the packaging bag is transported to the bottom of the coding device, and then the packaging bag is coded by the coding device. For example, a packaging bag film coding machine disclosed in a Chinese patent with authorization announcement number CN218315899U has the following working principle: "First, the end of the packaging bag film wrapped on the unwinding roller is pulled out, and then it passes over the first support roller, then passes between the two deflection correction columns, and then passes over the second support roller and the deflection correction wheel, and finally is wound on the winding roller. Then, the unwinding roller, the winding roller and the coding machine body are started at the same time. During the movement of the packaging bag film, coding can be performed. During the coding process, if the packaging bag film deviates to the left, the packaging bag film will contact the deflection correction column on the left, and drive the mounting rod to move to the left. Under the joint action of the rocker and the auxiliary rocker, the deflection correction wheel rotates counterclockwise, so that the packaging bag film moves to the right until the packaging bag film is centered; on the contrary, if the packaging bag film deviates to the right, the packaging bag film will contact the deflection correction column on the right, and drive the mounting rod to move to the right. Under the joint action of the rocker and the auxiliary rocker, the deflection correction wheel rotates clockwise, so that the packaging bag film moves to the left until the packaging bag film is centered."

[0004] Among them, coding of packaging bags means coding of packaging bags when the packaging bags pass under the main body of the coding machine. The main body of the coding machine adopts a fixed method. When coding the packaging bags in a fixed manner, only the designated position of the packaging bags can be coded, and the coding range cannot be changed, so that coding of different areas cannot be completed, which reduces the coding efficiency.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] Please refer to Figure 1-Figure 6 As shown, the utility model provides a coding device for plastic powder packaging bags, including a conveyor belt 1, a door frame 2 and a coding terminal 32, the door frame 2 is fixedly arranged on both sides of the conveyor belt 1, and a connecting plate 21 is fixedly connected between the tops of the door frames 2, and a first cylindrical gear 3 for mounting the coding terminal 32 is slidably arranged left and right below the connecting plate 21, and a screw rod 4 for driving the first cylindrical gear 3 to slide is arranged on the connecting plate 21.

[0022] A power mechanism for driving the screw rod 4 to rotate is telescopically arranged on one side of the door frame 2, and one end of the power mechanism is slidably inserted into the screw rod 4.

[0023] An adjusting mechanism meshingly connected with the power mechanism is rotatably provided at the top end of the inner wall of the portal frame 2 , and the adjusting mechanism meshes with the first cylindrical gear 3 .

[0024] In the present case, the conveyor belt 1 is used to convey packaging bags for packaging plastic powder. The screw rod 4 is arranged to facilitate adjustment of the left and right positions of the coding terminal 32. The first cylindrical gear 3 can also be adjusted to a position engaged with the adjusting mechanism by the rotation of the screw rod 4. At this time, the power mechanism is extended and retracted so that the power mechanism is disengaged from the screw rod 4. At the same time, the power mechanism is engaged with the adjusting mechanism, so that the adjusting mechanism rotates, and then the coding angle of the coding terminal 32 is adjusted.

[0025] When the coding angle needs to be changed, the screw rod 4 is rotated to adjust the first cylindrical gear 3 to mesh with the adjusting mechanism, and then the power mechanism is adjusted to make one end of the power mechanism disengage from the screw rod 4. At this time, the power mechanism is engaged with the adjusting mechanism, and the adjusting mechanism is driven by the power mechanism to rotate, and the adjusting mechanism is engaged with the first cylindrical gear 3, so that the first cylindrical gear 3 can be rotated to adjust the angle of the coding terminal 32 installed on the bottom surface of the first cylindrical gear 3, and the coding angle can be changed. By adjusting the horizontal and angle of the coding terminal 32, the coding position can be adjusted in all directions, so as to facilitate coding of different areas of the packaging bag, which greatly improves the coding efficiency and coding range.

[0026] A slide rod 31 is rotatably arranged on the top surface of the first cylindrical gear 3 , a slide groove 211 for the slide rod 31 to slide left and right is opened on the connecting plate 21 , the screw rod 4 is rotatably arranged in the slide groove 211 , and the screw rod 4 is threadedly connected to the slide rod 31 .

[0027] Through the setting of the sliding rod 31 , the sliding rod 31 is rotationally connected with the first cylindrical gear 3 , so as to facilitate the angle adjustment and horizontal adjustment of the dock 32 .

[0028] The rotation of the slide bar 31 and the first cylindrical gear 3 is a damped rotation. The first cylindrical gear 3 will not rotate without the help of external force, so as to prevent the first cylindrical gear 3 from self-rotating.

[0029] The power mechanism includes a mounting plate 5, a servo motor 52 and a bevel gear 521. The mounting plate 5 is arranged on one side of the portal frame 2. The servo motor 52 is fixedly arranged on the side of the mounting plate 5 close to the portal frame 2. The power output end of the servo motor 52 is fixedly connected to the bevel gear 521. A limit rod 522 is fixedly connected to the bevel gear 521 and is slidably inserted in the screw rod 4. The limit rod 522 is a square structure, and a square groove 41 is opened at one end of the screw rod 4 for the limit rod 522 to be slidably inserted.

[0030] An electric telescopic rod 51 is fixedly connected between the mounting plate 5 and the portal frame 2 .

[0031] By setting the electric telescopic rod 51, it is convenient to change the position of the mounting plate 5 and adjust the position of the mounting plate 5. By adjusting the position of the mounting plate 5, it is convenient to insert the limit rod 522 into the square groove 41. At this time, the bevel gear 521 is disengaged from the meshing with the adjustment mechanism. The start of the servo motor 52 can drive the limit rod 522 to rotate. The limit rod 522 is a square structure, which is convenient to drive the screw rod 4 to rotate, thereby realizing the horizontal adjustment of the hitting dock 32; wherein, the mounting plate 5 is driven to move by starting the electric telescopic rod 51, so that the bevel gear 521 is engaged with the adjustment mechanism. At this time, the limit rod 522 is disengaged from the limit of the square groove 41, so that the screw rod 4 no longer rotates, and the rotation of the bevel gear 521 makes it convenient to change the angle with the hitting dock 32 to adjust the angle.

[0032] The adjusting mechanism includes a rotating rod 6, a gear sleeve 61 and a second cylindrical gear 62. The rotating rod 6 is rotatably set on the top surface of the inner wall of the door frame 2. The outer periphery of the rotating rod 6 is fixedly connected to the gear sleeve 61. The gear sleeve 61 is meshed with the bevel gear 521. The second cylindrical gear 62 is fixedly connected to the bottom end of the rotating rod 6. The second cylindrical gear 62 is meshed with the first cylindrical gear 3.

[0033] Through the setting of the gear sleeve 61, when the angle of the dock 32 needs to be adjusted, the bevel gear 521 can be meshed and connected with the gear sleeve 61 through the movement of the bevel gear 521, the gear sleeve 61 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the second cylindrical gear 62 to rotate. The rotation of the second cylindrical gear 62 can drive the first cylindrical gear 3 to rotate, thereby driving the angle of the dock 32.

[0034] The rotation of the rotating rod 6 and the door frame 2 is a damped rotation. The rotating rod 6 will not rotate without the help of external force, so as to prevent the second cylindrical gear 62 from rotating on its own.

[0035] The above are only embodiments of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
