Description

Technical Field

[0001] The utility model relates to the technical field of buffer mechanisms, in particular to a film-feeding buffer mechanism for a packaging machine. Background Art

[0002] A packaging machine is a machine that puts items into packaging cans or bags for easy storage and transportation. Packaging machines usually seal the bags by moving film, which is usually done by using multiple sets of rollers.

[0003] However, the existing film feeding rollers are not equipped with a buffer mechanism. Therefore, when the pulling force changes during the film feeding process, for example, if the force is large during the film feeding process, the film may break, and when the pulling force is small, the film may loosen, which is inconvenient to use. Therefore, we propose a film feeding buffer mechanism for a packaging machine to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art involved in the background technology and proposes a film-feeding buffer mechanism for a packaging machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A film buffer mechanism for a packaging machine comprises a packaging machine body, a side wall of the packaging machine body is provided with a placement roller, a mounting frame is provided at the other end of the side wall of the packaging machine body, a connecting roller is provided inside the mounting frame, both ends of the connecting roller are provided with sliding blocks, both sides of the inner wall of the mounting frame are provided with sliding grooves, the sliding block extends to the inside of the sliding groove, a connecting rod is provided at the top of the sliding block, and the top end of the connecting rod passes through the mounting frame and extends to the top;

[0007] The film body is placed inside the placing roller, and then the film is pulled out and wrapped around the inside of multiple groups of connecting rollers in turn. The first group of connecting rollers can slide, thereby completing the buffering of the film moving process to avoid excessive or insufficient force affecting the efficiency of the film moving.

[0008] Preferably, a fixed shaft is provided inside the sliding slot, and the sliding block is sleeved on the outside of the fixed shaft;

[0009] The connecting roller can make the sliding block more stable, thus preventing the connecting roller from tilting and falling off.

[0010] Preferably, a mounting rod is provided above the mounting frame, and both ends of the mounting rod are fixedly connected to the connecting rod;

[0011] The strength of the connecting roller can be adjusted by controlling the strength of the mounting rod, making the buffering efficiency of the connecting roller more convenient.

[0012] Preferably, two groups of mounting seats are arranged at the top of the mounting frame, a connecting shaft is arranged between the two groups of mounting seats, and the mounting rod is sleeved on the outside of the connecting shaft;

[0013] The sliding stability of the mounting rod can be improved to prevent it from shaking and tilting.

[0014] Preferably, an extrusion adjustment block is sleeved on the outside of the connecting shaft rod, and a first support spring is also sleeved on the outside of the connecting shaft rod, one end of the first support spring is fixedly connected to the extrusion adjustment block, and the other end of the first support spring is fixedly connected to the mounting rod;

[0015] The first supporting spring can support the mounting rod, thereby completing the elastic force buffering of the mounting rod, and at the same time, the mounting rod controls the buffering of the sliding block and the connecting roller through the connecting rod.

[0016] Preferably, both ends of the extrusion adjustment block are inserted with limit rods, a pulling plate is provided at the top of the extrusion adjustment block, both ends of the pulling plate are fixedly connected to the ends of the limit rods, and the top of the mounting frame is provided with an embedding groove that is mutually compatible with the limit rods;

[0017] The pulling plate can be pulled so that the pulling plate drives the limiting embedded rod to disengage from the embedded groove at the top of the mounting frame, and then the position of the extrusion adjustment block can be adjusted so that the extrusion adjustment block squeezes the first support spring, thereby changing the buffering force of the first support spring on the mounting rod.

[0018] Preferably, a second support spring is sleeved on the outside of the limiting embedded rod, one end of the second support spring is fixedly connected to the pulling plate, and the other end of the second support spring is fixedly connected to the end of the extrusion adjustment block;

[0019] When the pulling plate is released, the second supporting spring drives the limiting embedded rod to recover, so that the limiting embedded rod is better embedded in the embedding groove, and the limiting embedded rod is prevented from being separated from the embedding groove.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The utility model can make the connecting roller drive the sliding block to slide inside the sliding groove, and at the same time drive the connecting rod and the mounting rod to move. The mounting rod contacts the first supporting spring during the movement, so that the first supporting spring can buffer the movement of the mounting rod, thereby completing the buffering of the connecting roller, avoiding the influence of the film walking force change on the film walking, and making the film walking effect better.

[0022] 2. The utility model can pull the pulling plate so that the pulling plate drives the limiting embedded rod to leave the embedded groove at the top of the mounting frame, and then the position of the extrusion adjustment block can be adjusted, which is convenient for adjusting the elastic coefficient of the first support spring. The buffering force can be adjusted according to the membranes of different thicknesses, further improving the buffering effect of the membrane. BRIEF DESCRIPTION OF THE DRAWINGS
