Description

Technical Field

[0001] The utility model relates to a component on a bag feeding machine, in particular to a machine clamp following clamping mechanism of the bag feeding machine. Background Art

[0002] The structure of the machine clamp on the bag feeding machine mainly includes a turntable and machine clamp components evenly distributed on the circumference of the turntable. The packaging bag is clamped by the machine clamp components so that the bag opening is opened for feeding or the bag is closed for heat sealing. When the bag feeding machine is packaging some strip-shaped or plate-shaped food materials, after these materials are put into the bag, the rotation of the turntable will cause the materials to move up and down and left and right in the packaging bag. After the materials are packaged, the packaging bag can be seen through and it can be found that the materials are not neat, which greatly affects the appearance of the material packaging, thus greatly reducing the purchaser's desire to buy and having a great impact on the sales volume of the goods. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a machine clamp follower clamping mechanism of a bag feeding machine, the purpose of which is to position the material in time after it enters the bag, prevent the material from moving randomly in the packaging bag, and thus ensure the quality of the material packaging.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a machine clamp following clamping mechanism of a bag feeding machine, comprising a turntable installed on a rotating shaft, the rotating shaft is driven by a motor, and a machine clamp component evenly distributed around the circumference is arranged at the edge of the turntable, the machine clamp component comprises two symmetrically arranged clamping arms, the tail ends of the two clamping arms are respectively provided with mutually meshing fan gears, the front ends of the two clamping arms are respectively provided with openable and closable bag mouth clamps, a clamping assembly for clamping the bag body is arranged on the clamping arm, and a control mechanism for controlling the opening and closing of the clamping assembly is arranged corresponding to the clamping assembly.

[0005] The clamping assembly includes a bracket connected to the clamping arm, a finger cylinder is installed on the bracket, and clamping plates are respectively installed on the two finger parts of the finger cylinder. The control mechanism includes a mechanical valve that corresponds to and is connected to the finger cylinder one by one. The mechanical valve is installed on the turntable, and an arc-shaped cam circle is set on the inner circle of the turntable. An elastic switch is arranged on the mechanical valve, and a roller is arranged on the elastic switch. The roller contacts the high point or low point on the cam circle during the rotation of the turntable.

[0006] The control mechanism also includes a cylinder, which is arranged at the notch position of the cam ring. When the mechanical valve moves to the notch position of the cam ring, the output shaft of the cylinder controls the elastic switching action of the mechanical valve.

[0007] The beneficial effect of the utility model is that the clamping components rotating with the turntable clamp the two sides of the bag opening of the packaging bag. After the material is loaded, the bag body can be clamped in time by the clamping components, so that the material in the bag body is positioned. In this way, the material can be positioned in time after entering the bag, preventing the material from moving randomly in the packaging bag, thereby ensuring the quality of the material packaging.

DETAILED DESCRIPTION

[0013] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.

[0014] like Figure 1 — Figure 3 As shown, the present embodiment discloses a machine clamp following clamping mechanism of a bag feeding machine, including a turntable 1 mounted on a rotating shaft, the rotating shaft is driven by a motor, a machine clamp component 2 evenly distributed around the circumference is arranged on the edge of the turntable 1, the machine clamp component 2 includes two symmetrically arranged clamping arms 21, the tail ends of the two clamping arms 21 are respectively provided with mutually meshing fan gears, the front ends of the two clamping arms 21 are respectively provided with openable and closable bag mouth clamps, and the two clamping arms 21 are both provided with clamping components 3 for clamping the bag body. Of course, the clamping component 3 can also be provided on one of the clamping arms 21, so that the clamping component 3 can follow the clamping arm 21, and the corresponding clamping component 3 is provided with a control mechanism 4 for controlling the opening and closing of the clamping component 3.

[0015] The clamping assembly 3 includes a bracket 5 connected to the clamping arm 21, a finger cylinder 6 is installed on the bracket 5, and clamping plates 7 are respectively installed on the two finger pieces of the finger cylinder 6. The clamping plate 7 needs to clamp the middle position of most of the bag body, so the size needs to be adapted according to the specifications of the bag body. The control mechanism 4 includes a mechanical valve 41 that corresponds to and is connected to the finger cylinder 6, so that the mechanical valve 41 controls the opening and closing of the finger cylinder 6, and then controls the opening and closing of the clamping plate 7. The mechanical valve 41 is installed on the turntable 1, and an arc-shaped convex The wheel rim 42 and the mechanical valve 41 are provided with an elastic switch 411, and the elastic switch 411 is provided with a roller. The roller will contact with the high point or the low point on the cam ring 42 during the rotation of the turntable 1, so that the clamping plate 7 can be controlled to follow the operation of the clamping arm 21, so that the roller always rolls on the high point of the cam ring 42 in the bag loading station, the unloading station and the heat sealing station, so that the clamping plate 7 always remains in a closed state. At the bag dropping station, the roller moves from the high point of the cam ring 42 to the low point, so that the clamping plate 7 is converted into an open state to facilitate bag dropping.

[0016] The mechanical valve is an SMC-5-way mechanically controlled valve, model VZM550-01-01S.

[0017] The control mechanism 4 also includes a cylinder 43, which is arranged at the notch position of the cam ring. When the mechanical valve moves to the notch position of the cam ring 42, the output shaft of the cylinder 43 controls the elastic switch action of the mechanical valve. The cylinder 43 corresponds to the bag loading and unloading stations of the bag feeding machine. When the two clamping arms 21 rotate to the loading station, before the turntable 1 starts after the bag is loaded, the mechanical valve 41 is driven by the cylinder 43 to compress, so that the clamping plate 7 is closed to avoid the clamping plate 7 opening and colliding with the bag loading column during operation. At the unloading station, before the turntable 1 starts after the material is bagged, the mechanical valve is driven by the cylinder 43 to compress, so that the clamping plate 7 is closed to clamp the material. The rear section makes the clamping plate 7 in a compressed state through the high point of the cam ring 42 to avoid the material from being scattered and dislocated during intermittent operation. At the heat sealing station, the mechanical valve 41 runs from the high point to the low point on the cam ring 42 after heat sealing. During operation, the mechanical valve is reset to open the clamping plate 7 to facilitate safe bag dropping at the bag dropping station.

[0018] By adopting the above technical scheme, the clamping component 2 rotating with the turntable 1 clamps the two sides of the bag opening of the packaging bag. After the material is loaded, the bag body and the material can be clamped in time by the clamping component 3, so that the material in the bag body can be positioned. In this way, the material can be positioned in time after entering the bag to prevent the material from moving randomly in the packaging bag, thereby ensuring the quality of the material packaging.

[0019] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0020] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
