Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for a cloth packaging machine. Background Art

[0002] A packaging machine is a type of machine that packages products to protect and beautify them. Packaging machines are mainly divided into two aspects: assembly line-type overall production packaging and product peripheral packaging equipment. The punching device is used to punch holes in the packaging bag to ensure air permeability.

[0003] For example, the public document with application number 202220213463.6 discloses a hydraulic drilling device for oil pipes. The utility model holds the middle of the first connecting rod tightly to pass one end of the annular handle through the inner wall of the pipe to be drilled, and places the drilling head at the top of the position to be drilled. Then, the annular handle is rotated to drive the third connecting rod to rotate, and one end of the first support rod moves upward until the support block touches the inner wall of the pipe. The spring supports the support block, and the top of the support block fits the inner wall of the pipe to be drilled. The hydraulic lifting rod is started to drive the drilling head to touch the outer wall of the pipe, so as to achieve the effect of supporting the pipe and preventing the pipe from deforming after drilling. However, the drilling device uses a hydraulic cylinder to drill holes. During the drilling process, it is necessary to continuously drive the hydraulic cylinder piston rod to extend and retract. The high-frequency changes will cause serious wear of the sealing ring of the hydraulic cylinder, resulting in oil leakage from the hydraulic cylinder, thereby reducing the service life of the device.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a punching device for a cloth packaging machine is proposed. Utility Model Content

[0007] Preferably, the circulation mechanism includes a driving motor arranged at the upper end of the outer surface of the installation box, and the output end of the driving motor passes through the installation box and is provided with a roller, the surface of the roller is provided with a vertical slide, the surface of the roller is provided with an arc slide on one side of the vertical slide, two groove plates are fixedly installed on the front side of the surface of the installation box, a tension spring is fixedly installed on the top end of the inner surface of the groove plate, a movable plate is fixedly installed on the lower end of the tension spring, and a transmission rod is fixedly installed on the middle part of the rear side of the surface of the movable plate.

[0008] Preferably, the bottom end of the roller is rotatably disposed on the inner surface of the mounting box via a bearing, and the vertical slide is connected to the arc-shaped slide.

[0009] Preferably, the rear end of the transmission rod is slidably located inside the two slideways, and the punching head is fixedly connected to the middle part below the surface of the movable plate.

[0010] Preferably, limit rollers are rotatably arranged on both left and right sides of the groove of the punching table through bearings, and fixing frames are fixedly installed on the front and rear sides of the left end above the outer surface of the punching table.

[0011] Preferably, a focusing roller is rotatably provided on the upper side of the opposite side of the fixing frame via a bearing, and a rotating motor is installed at the front end of the focusing roller passing through the fixing frame, and the rotating motor is fixedly connected to the surface of the front fixing frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can reciprocate and drive the punching head to move up and down to perform fully automatic cyclic punching through the arrangement of a circulation mechanism, a driving motor, a rotating roller, a vertical slideway, an arc-shaped slideway, a groove plate, a tension spring, a movable plate, a transmission rod and a punching head, and the rotation speed of the rotating roller remains unchanged, and the time interval of the up and down movement of the punching head is the same.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 2 As shown, a punching device of a fabric packaging machine comprises a punching table 1, a support frame 2 is fixedly installed on the right side above the outer surface of the punching table 1, a mounting box 3 is fixedly installed through the middle part of the upper part of the support frame 2, a circulation mechanism 4 is arranged on the surface of the mounting box 3, a punching head 5 is arranged on the front lower side of the mounting box 3, the circulation mechanism 4 comprises a driving motor 401 arranged on the upper end of the outer surface of the mounting box 3, and a roller 402 is arranged on the output end of the driving motor 401 through the mounting box 3, a vertical slide 403 is opened on the surface of the roller 402, and the surface of the roller 402 is located on one side of the vertical slide 403 An arc-shaped slide 404 is provided, and two groove plates 405 are fixedly installed on the front side of the surface of the installation box 3. A tension spring 406 is fixedly installed on the top of the inner surface of the groove plate 405, and a movable plate 407 is fixedly installed on the lower end of the tension spring 406. A transmission rod 408 is fixedly installed on the middle part of the rear side of the surface of the movable plate 407. The bottom end of the roller 402 is rotatably arranged on the inner surface of the installation box 3 through a bearing. The vertical slide 403 is connected to the arc-shaped slide 404, and the rear end of the transmission rod 408 is slidably located inside the two slides, and the punching head 5 is fixedly connected to the middle part below the surface of the movable plate 407.

[0021] Furthermore, the arc-shaped slideway 404 on the surface of the roller 402 will change position as the roller 402 rotates, and then use the arc-shaped inclined surface to push the transmission rod 408 downward, driving the movable plate 407 and the punching head 5 to move downward for punching.

[0022] Furthermore, the vertical slide 403 is opened in a vertical state, and there is a vertical cavity above it, which will not push or press the transmission rod 408. At this time, the transmission rod 408 can quickly rebound and move upward to reset through the tension spring 406.

[0023] Furthermore, the vertical slide 403 and the arc slide 404 are connected, and when the roller 402 rotates, the positions of the two slides are constantly changing, so that the transmission rod 408 can continuously move in the two slides, thereby driving the punching head 5 to continuously move up and down in a circular motion, performing automatic and efficient cyclic punching work.

[0024] like Figure 1 and Figure 3 As shown, limiting rollers 6 are rotatably provided on the left and right sides of the groove of the punching table 1 through bearings, and fixing frames 7 are fixedly installed on the front and rear sides of the left end above the outer surface of the punching table 1, and a focusing roller 8 is rotatably provided on the opposite side of the fixing frame 7 through bearings, and a rotating motor 9 is installed at the front end of the focusing roller 8 through the fixing frame 7, and the rotating motor 9 is fixedly connected to the surface of the front fixing frame 7.

[0025] Furthermore, the limiting roller 6 can effectively limit the surface of the packaging bag inside the groove to ensure that the packaging bag remains flat during the punching process.

[0026] Furthermore, the collecting roller 8 is located on the left side of the punching head 5 and can automatically collect the punched packaging bags.

[0027] Furthermore, when collecting the packaging bags, the focusing roller 8 will also pull the subsequent un-punched packaging bags to move, while the rotation collection rate of the focusing roller 8 remains unchanged, the packaging bag traction movement rate is a constant speed, and the rotation rate of the rotating roller 402 remains unchanged, that is, the up and down movement rate and time interval of the punching head 5 are the same. The combination of the two can make the holes on the surface of the packaging bag have a consistent and even distribution.

[0028] Working principle: When using the punching device of the fabric packaging machine, first, pass one end of the packaging bag through the bottom of the limiting roller 6 and fix it on the gathering roller 8, start the rotating motor 9 and the driving motor 401 synchronously, the driving motor 401 drives the roller 402 to rotate, so that the positions of the vertical slide 403 and the arc slide 404 are constantly changing, and the arc slide 404 will use its own inclined surface to push the transmission rod 408 to gradually move downward, thereby driving the movable plate 407 to move downward, and stretching the tension spring 406, so that the punching head 5 moves downward to punch holes in the packaging bag. When the arc slide 404 ends, the transmission rod 408 will enter the vertical slide 403, and the vertical slide 403 cannot push the transmission rod 408, and then under the rebound force of the tension spring 406, it will Quickly pull the movable plate 407 and the transmission rod 408 upward, thereby driving the punching head 5 to move upward. Since the vertical slide 403 and the arc slide 404 are connected, as the roller 402 continues to rotate, the transmission rod 408 will once again enter the arc slide 404, and the punching head 5 will be driven to move up and down reciprocatingly to perform fully automatic cyclic punching work, and the rotating motor 9 will drive the gathering roller 8 to rotate, automatically collect the punched packaging bags, and pull the unpunched packaging bags into the punching table 1, while the rotation and winding speed of the gathering roller 8 remains unchanged, so that the movement speed of the packaging bag remains constant, and the punching head 5 moves up and down at a constant interval, so that the interval of the holes on the entire packaging bag surface remains consistent. This is the working principle of the punching device of the fabric packaging machine.
