Description

Technical Field

[0001] This utility model relates to the field of bag making machinery technology, and in particular to a bag opening punching mechanism for a bag making machine. Background Technology

[0002] In the field of packaging machinery, the bag opening punching mechanism of a bag making machine directly affects the forming quality of the packaging bag.

[0003] The existing patent authorization announcement number: CN220763717U, discloses a punching device for a bag making machine, including a side plate. A rectangular groove is fixedly provided on the upper surface of the side plate. A threaded rod is rotatably provided inside the rectangular groove. A first screw is threaded at one end of the threaded rod. A threaded sleeve is threaded on the outside of the threaded rod. A cylinder is fixedly provided at the lower part of the threaded sleeve. A rectangular frame is fixedly provided in the middle of the side plate. This utility model, through the arrangement of the threaded rod and threaded sleeve, allows the operator to rotate the handle to rotate the threaded rod, adjust the hydraulic press to the desired position, and rotate the first screw to fix the threaded sleeve. The threaded rod, through its threaded arrangement, drives the threaded sleeve to move left and right on its surface. The lower end of the threaded sleeve is fixedly connected to the hydraulic press through the cylinder. The displacement of the threaded sleeve drives the displacement of the hydraulic press, thereby achieving the effect of adjusting the opening position and avoiding the inability to adapt to different punching positions.

[0004] However, this device has the following drawbacks: it only achieves lateral fine-tuning through a screw, failing to simultaneously compensate for longitudinal deviations, leading to punching position errors. Furthermore, the adjustment of the hollow circular groove and hydraulic column requires step-by-step operation, easily introducing secondary errors. To address these shortcomings, we propose a bag-mouth punching mechanism for a bag-making machine. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a bag punching mechanism for a bag making machine, including a positioning base, which is composed of a left fixed seat 10 and a right fixed seat 20. A clamping assembly is provided below the left fixed seat 10 and the right fixed seat 20. The clamping assembly includes a clamping plate 60, a fixing bolt 61 threadedly connected to the surface of the clamping plate 60, and threaded holes opened on the lower surfaces of the left fixed seat 10 and the right fixed seat 20. A clamping groove 62 with anti-slip rubber pads is opened on the upper surface of the clamping plate 60 and the lower surface of the left fixed seat 10 and the right fixed seat 20. The groove shape of the clamping groove 62 matches the mounting bracket of the bag punching machine.

[0027] Place the left fixed seat 10 and the right fixed seat 20 on the bag punching machine mounting bracket. Then place the clamping plate 60 on the other side of the bag punching machine mounting bracket. The left fixed seat 10 and the right fixed seat 20 can be installed on the bag punching machine mounting bracket by clamping plate 60 and fixing bolt 61. After tightening the fixing bolt 61, clamping plate 60 presses the bracket. The anti-slip rubber pad in the clamping groove 62 contacts the bracket to enhance friction, prevent processing vibration from causing loosening and ensure stability.

[0028] A lateral adjustment assembly is provided between the left fixed seat 10 and the right fixed seat 20. The lateral adjustment assembly includes two lateral guide rods 50 symmetrically fixed to the right side of the left fixed seat 10, a through lateral guide hole opened on the left side of the right fixed seat 20, and an adjusting screw 51 threadedly connected to the right side of the right fixed seat 20. The end of the adjusting screw 51 passes through the right fixed seat 20 and is rotatably connected to the right end of the left fixed seat 10. The lateral guide rods 50 and the lateral guide holes are slidably engaged. When the right fixed seat 20 is fixed on the external bag making machine mounting bracket and the left fixed seat 10 is kept sliding on the external bag making machine mounting bracket, rotating the adjusting screw 51 can push the left fixed seat 10 to move, thereby finely adjusting the left and right positions between the left fixed seat 10 and the right fixed seat 20. The lateral guide rods 50 and the lateral guide holes ensure smooth movement without deviation.

[0029] A device base 30 is provided above the left fixed seat 10. The left fixed seat 10 has a longitudinal adjustment component inside. The device base 30 is fixed to the bag punching machine 40 by bolts.

[0030] The longitudinal adjustment assembly includes a longitudinal guide rod 70 symmetrically fixedly mounted on the inner wall of the left fixed seat 10, a through longitudinal guide hole opened on the surface of the equipment base 30, a threaded rod 71 rotatably connected to the inner wall of the left fixed seat 10, and a nut seat 72 that is helically driven with the threaded rod 71. The upper end of the nut seat 72 is fixedly connected to the lower end of the equipment base 30. The end of the threaded rod 71 is provided with a handwheel, the axis of rotation of which is parallel to the longitudinal guide rod 70, and the longitudinal guide rod 70 is slidably engaged with the longitudinal guide hole.

[0031] By rotating the handwheel at the end of the threaded rod 71, the nut seat 72 is driven to move back and forth along the longitudinal guide rod 70, which in turn drives the equipment base 30 to move back and forth, thereby realizing the adjustment of the front and back position of the bag punching machine 40. The longitudinal guide rod 70 and the longitudinal guide hole cooperate to ensure that the movement trajectory is stable and without deviation.

[0032] After the bag punching machine 40 is installed on the equipment base 30, the device can adjust the lateral position of the equipment base 30 by using the lateral adjustment component and adjust the front and rear position of the equipment base 30 by using the longitudinal adjustment component, thus solving the position error problem caused by single-axis adjustment in the existing technology.

[0033] Both the equipment base 30 and the right-side fixed seat 20 are equipped with locking components. The locking components include sliding grooves respectively opened in the inner walls of the transverse guide hole and the longitudinal guide hole, locking clamps 80 slidably installed in the inner walls of the sliding grooves, and locking bolts 81 threadedly connected to the surfaces of the equipment base 30 and the right-side fixed seat 20. The clamping surface of the locking clamps 80 is provided with rubber anti-slip texture. The threaded end of the locking bolts 81 extends into the interior of the sliding groove and is rotatably connected to the locking clamps 80. When the locking bolts 81 are rotated, their threaded end pushes the locking clamps 80 to move along the sliding groove. The rubber anti-slip texture forms a friction lock with the transverse guide rod 50 and the longitudinal guide rod 70. After the position of the bag punching machine 40 is adjusted, the locking bolts 81 are tightened, so that the locking clamps 80 can be used to clamp the longitudinal guide rod 70 and the transverse guide rod 50 respectively, thereby improving stability.

[0034] Specifically, the working principle and operation method of this utility model are as follows:

[0035] 1. Install positioning base
