An electric push rod is arranged at the upper end of the base, when a screw button is rotated to make a fixing block move forwards, a sliding block can stably move in a second limiting groove, a sliding rod on a sliding sleeve moves in a third limiting groove through transmission, and when the fixing block stably moves forwards to extrude a bag opening, bristles are triggered to synchronously trigger the bag opening up and down in a reciprocating mode; and when the sliding rod operates in the third limiting groove, the multi-angle and multi-layer touch effect can be formed on the bag opening, and therefore the problems that when food and other objects are attached to the inner side of the bag opening, the bag opening positioning and sealing effect is greatly reduced, and consequently a follow-up sealing machine cannot conduct normal sealing operation are solved.

Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, and specifically relates to a packaging machine with a positioning structure. Background Technique

[0002] A beef ball food packaging machine is a machine specifically used for automatically packaging foods such as beef balls. It can automatically load beef balls into bags or boxes and complete packaging operations such as sealing and labeling.

[0003] According to a disclosed food packaging machine with a positioning structure (Publication No.: CN220263389U), in the above application, by applying pressure on the positioning mechanism, the positioning frame can be lifted and lowered on the support rod, so that the positioning mechanism can package food packaging bags at different heights, which greatly improves the flexibility and applicability of the packaging machine. By rotating the hand-tightening rod, the adjusting plate can be moved, and the balance blocks on both sides of the adjusting plate will move on the connecting rod, so as to ensure that the adjusting plate can more stably position the bag mouth of the packaging bag, thereby improving the accuracy and stability of packaging.

[0004] However, during the actual use of the above device, although the adjusting plate can be moved by rotating the hand-tightening rod to ensure that the adjusting plate can more stably position the bag mouth of the packaging bag, when there are objects such as food attached to the inner side of the bag mouth, the bag mouth positioning and sealing effect will be greatly reduced, resulting in the subsequent sealing machine being unable to perform normal sealing operations. In view of this, we propose a packaging machine with a positioning structure. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A packaging machine with a positioning structure, including a base, a blanking assembly is arranged at the upper end of the base, a sealing and pressing assembly is arranged at the upper end of the base, a positioning assembly is arranged at the upper end of the base, the positioning assembly includes an electric push rod, an electric push rod is arranged at the upper end of the base, the output end of the electric push rod is fixedly connected with a fixed sleeve, a first limiting groove is opened on the outer surface of the fixed sleeve, a second limiting groove is opened on the inner wall of the first limiting groove, a first installation groove is opened on the inner wall of the first limiting groove, a third limiting groove is opened on the inner wall of the first limiting groove, a screw button is threadedly connected to the outer surface of the fixed sleeve, the end of the screw button is fixedly connected with a fixed block, the outer surface of the fixed block is fixedly connected with a sliding block, the outer surface of the sliding block is movably connected to the outer wall of the second limiting groove, a U-shaped frame is fixedly connected to the side wall of the fixed block, and a sliding sleeve is slidably connected to the outer surface of the U-shaped frame;

[0007] The outer wall of the sliding sleeve is fixedly connected with a touching brush hair. The side wall of the sliding sleeve is fixedly connected with a sliding rod. The end of the sliding rod is movably connected to the inner wall of the third limiting groove. The inner wall of the first installation groove is provided with an elastic telescopic plate. The outer surface of the sliding rod is movably connected to the top end of the elastic telescopic plate. The outer wall of the elastic telescopic plate is fixedly connected with a connecting rod. The end of the connecting rod is fixedly connected to the outer wall of the elastic telescopic plate. The outer surface of the connecting rod is fixedly connected with a mounting plate. The outer surface of the connecting rod is fixedly connected with a contact rubber plate.

[0008] Preferably, the third limiting groove is arranged in a wavy shape, so that the sliding rod can move smoothly in the third limiting groove.

[0009] Preferably, the center lines of the second limiting groove and the first installation groove are in the same plane, so that the whole can operate smoothly.

[0010] Preferably, the number of the touching brush hairs is several, and the several touching brush hairs are arranged in a linear array on the outer wall of the sliding sleeve, so that the touching brush hairs can touch the bag mouth in contact when moving.

[0011] Preferably, an optimization component is arranged on the outer surface of the sliding sleeve. The optimization component includes a first tooth clip. The first tooth clip is fixedly connected to the outer wall of the sliding sleeve. The second tooth clip is fixedly connected to the outer wall of the mounting plate.

[0012] Preferably, the first tooth clip and the second tooth clip are arranged in a staggered form, so that the bag mouth of the packaging bag can be better sealed.

[0013] Compared with the prior art, the utility model provides a packaging machine with a positioning structure, and has the following beneficial effects:

[0014] 1. For the packaging machine with a positioning structure, when the fixed block moves forward by rotating the screw knob, the sliding block will move smoothly in the second limiting groove. Through transmission, the sliding rod on the sliding sleeve will move in the third limiting groove. When the fixed block moves forward smoothly and squeezes the bag mouth, the touching brush hairs can reciprocate up and down the bag mouth synchronously. And when the sliding rod moves in the third limiting groove, through transmission, the elastic telescopic plate will drive the contact rubber plate to touch the other side of the bag mouth. Finally, when the fixed block squeezes the bag mouth, a multi-angle and multi-layer touching effect can be formed on the bag mouth, so as to solve the problem that when there are objects such as food attached to the inner side of the bag mouth, the positioning and sealing effect of the bag mouth will be greatly reduced, resulting in the subsequent sealing machine being unable to perform normal sealing operation.

[0015] 2. For the packaging machine with a positioning structure, when the sliding rod on the sliding sleeve moves within the third limiting groove through transmission to form a situation where the fixed block moves forward steadily to squeeze the bag mouth, and the bristles are touched to reciprocate up and down on the bag mouth synchronously, the first tooth clip will also operate synchronously. Eventually, the first tooth clip and the second tooth clip form a further positioning and sealing effect on the bag mouth, enabling better sealing operation of the subsequent sealing function, and thus greatly improving the overall practicality.
