Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and more specifically, to a continuous material bag shearing device. Background Art

[0002] At present, instant noodles, hot pot and other foods occupy an important position in people's lives, and the various seasoning packages directly determine the taste. With the increasing demand for such convenient foods, the demand for continuous packaging bag production is increasing. While focusing on increasing production, food safety is also particularly important.

[0003] The problem of material jamming is prone to occur during the production process of continuous packaging bags, that is, the seasoning is caught at the connection between two bags due to equipment or other reasons, or the seasoning or sauce leaks due to poor sealing. Oil pollution may cause deterioration or even mildew, thus affecting the quality and safety of food; it violates the provisions of the Food Safety Law that "it is prohibited to produce food and food additives that are corrupt, rancid, moldy, filthy, mixed with foreign matter, adulterated, or have abnormal sensory properties." In the entire field of convenient foods, it is not uncommon for oil stains to appear in barrels / bowls / bags when continuous packaging bags are damaged (or intact).

[0004] At present, the production of continuous packaging bags generally adopts filling machines for mass production. However, in order to deal with the problems of material clamping and leakage at the sealing point, the industry still adopts the traditional detection method of manual naked eye. Through spot checks and gradual inspections with the naked eye, the continuous packaging bags with material clamping and other unqualified continuous packaging bags are manually cut off and removed through the cutting mechanism. Then, the continuous packaging bag strips are manually bonded with tape. There are problems such as low detection efficiency, high labor intensity, poor spot check results, high detection costs, and troublesome removal and bonding. Obviously, it can no longer meet the needs of modern enterprise development. Since the continuous packaging bags need to be cut and then pasted together in the process, the cutting mechanism and the pasting mechanism need to be set at the same time in the local adjacent position. This requires the cutting mechanism to be small in size and compact in structure, leaving installation and operation space for the pasting mechanism. However, there is no such structure on the market that can solve the above problems well. Utility Model Content

During the movement of the chain, the Z-direction guide rail and the pneumatic scissors are driven to move downward along the vertical part of the L-shaped slide groove, and then move to the bottom of the L-shaped slide groove, and then drive the Z-direction guide rail and the pneumatic scissors to move horizontally along the L-shaped slide groove. While the Z-direction guide rail moves horizontally, it also moves horizontally relative to the X-direction guide rail, and moves horizontally to the end of the horizontal part of the L-shaped slide groove. The pneumatic scissors are in the shearing position state, indicating that the pneumatic scissors have moved into place, and the pneumatic scissors are driven The pneumatic scissors are opened after the action of closing and shearing the material strip is completed, and the driving chain moves in the opposite direction to make the pneumatic scissors return to the initial position along the L-shaped slide groove, leaving operating space for the subsequent pasting mechanism action; in the continuous material bag shearing device of the utility model, the transmission mechanism is cleverly arranged, and the up and down and lateral movements of the scissors are realized by a driving motor at the same time, which simplifies the structure and equipment composition, and the overall volume occupied by the mechanism is small, which is conducive to docking and coordination with other equipment and mechanisms.

[0017] The Z-guide rail is connected to the chain through the fork assembly and the guide bearing. The guide bearing and the fork assembly are tightly connected and rolled with friction. The friction is small, which is beneficial to reduce device wear, extend device service life and reduce work consumption. A roller is set at the outer end of the guide bearing's mounting shaft and the roller and the L-shaped slide groove are rolled and guided to reduce friction and improve the smoothness of the pneumatic scissors movement. When two guide bearings are set, they have a better matching and supporting effect.

[0018] The Z-direction limit screw and the X-direction limit screw are used to limit the Z-direction position end and the X-direction position end of the Z-direction guide rail and the pneumatic scissors respectively. The limit screws are fixed on the limit plate by threaded installation. The position of the limit screws can be rotated to adjust the Z-direction position end and the X-direction position end of the pneumatic scissors;

[0019] The purpose of setting the Z-direction slot photoelectric and the X-direction slot photoelectric is to sense whether the pneumatic scissors have moved into place. When the pneumatic scissors move to the cutting position, the X-direction slot photoelectric sends a cutting in place signal to the controller, and the controller can control the pneumatic scissors to perform the cutting action; when the pneumatic scissors return to the initial position, the Z-direction slot photoelectric sends an initial in place signal to the controller, and the controller can control the subsequent mechanism (such as the pasting mechanism) to act, and the automatic cutting and pasting assembly line operation of the material strip is realized through the sensor element and the controller without interference.

In this embodiment, the roller constitutes a guide member in the L-shaped slide groove, and the roller and the L-shaped slide groove 136 maintain rolling friction cooperation, which reduces the friction force and ensures that the pneumatic scissors 123 move smoothly and steadily. A guide bearing 108 is also installed on the mounting shaft 109, and the chain is connected to the guide bearing 108 through a fork assembly, wherein the fork assembly includes two U-shaped forks 135 and a connecting shaft 110, and the two U-shaped forks 135 are respectively located on both sides of the chain, and the U-shaped fork 135 includes a bottom and two fork arms extending outward along the bottom, and the bottom of the U-shaped fork 135 is connected to the chain, and the connecting shaft 110 is connected between the fork arms of the two U-shaped forks, and is used to limit the guide bearing 108 inside the fork assembly and roll with the guide bearing 108. In specific operation, the chain 102 drives the Z guide rail 111 to move through the fork assembly and the knife shaft bearing.

The Z-direction limit plate 106 and the X-direction limit plate 125 are respectively threadedly mounted with adjustable Z-direction limit screws 107 and X-direction limit screws 124. By adjusting the extension length of the Z-direction limit screws 107 and the X-direction limit screws 124, the position of the Z-direction stroke end and the X-direction stroke end can be changed.

In addition to controlling the connection of the pneumatic scissors, the controller is also connected to other mechanisms on the filling machine, such as a pasting mechanism. The pneumatic scissors have the following features: Figure 3 As shown in FIG. 1 , the L-shaped chute is moved to the initial position of the vertical end of the L-shaped chute, and also has the following Figure 5 As shown, the pneumatic scissors move to the shearing position state of the horizontal end of the L-shaped slide groove. When the pneumatic scissors are in the shearing position state, the X-direction slot photoelectric senses the X-direction signal board and sends a shearing in place signal to the controller. The controller receives the shearing in place signal and controls the scissors to cut; when the pneumatic scissors are in the initial position state, the Z-direction slot photoelectric senses the Z-direction signal board and sends an initial in place signal to the controller. The controller receives the initial in place signal, indicating that the pneumatic scissors are fully retracted and the pasting mechanism can be operated to act, thereby ensuring automated and interference-free operation.

[0034] When the continuous material bag shearing device is in use, in the initial position state, the driving element drives the active sprocket to rotate and makes the chain move, and the chain drives the Z-guide rail and the pneumatic scissors to move downward along the L-shaped slide groove, and when it moves to the intersection of the horizontal part and the vertical part of the L-shaped slide groove, it drives the Z-guide rail and the pneumatic scissors to move horizontally along the L-shaped slide groove. At the same time, the Z-guide rail also moves horizontally relative to the X-guide rail. When the Z-guide rail moves to the horizontal end of the L-shaped slide groove, the X-direction slot photoelectric senses that the X-direction signal board sends a shearing in place signal to the controller, and the controller controls the pneumatic scissors to close and shear the material strip. After the shearing is completed, the pneumatic scissors open; the driving chain moves in the opposite direction to make the pneumatic scissors return to the initial position state along the L-shaped slide groove, and the Z-direction slot photoelectric senses that the Z-direction signal board sends an initial in place signal to remind the pneumatic scissors that they have been fully retracted and make room for the subsequent pasting mechanism action, and the controller operates the subsequent pasting mechanism action.

[0035] In summary, the utility model realizes the horizontal and vertical movement of the pneumatic scissors simultaneously through a driving motor. The transmission mechanism structure is ingenious, which simplifies the structure and equipment composition, makes the overall equipment occupy a small volume, and is convenient for docking with other equipment and mechanisms. It can not only reduce labor intensity, but also improve the mechanization level of the production process. It has low cost, strong practicality, and is suitable for popularization.
