Abstract
Description
Technical Field
[0001] The utility model relates to bag-making equipment, in particular to an adjustable handle positioning and pushing device of a bag-making machine. Background Art
[0002] A bag-making machine is a special device used for automatically forming packaging bags. One type of packaging bag has a handle attached to the bag body. During the production process, the formed handle needs to be pushed to the handle-attaching station by a handle-pushing device to attach the handle to the bag body. Currently, the handle-pushing device on the market mainly includes a pushing chain, on which a pushing member is provided. By controlling the movement of the pushing chain, the pushing member can be driven to move to achieve the pushing operation of the handle. The defect of the above structure is that the pushing member is often fixed on the pushing chain, which results in a fixed pushing path of the pushing member. However, in actual use, the handles have many different specifications. If the handle is large, it may cause the handle to be pushed too far, or the front and rear pushed handles may be squeezed and stacked. If the handle is small, it may cause the handle to be pushed too close, both of which will affect the subsequent handle bonding operation. Utility Model Content
[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide an adjustable handle positioning and pushing device for a bag making machine for solving the above-mentioned problem.
[0004] To this end, the present invention is implemented by adopting the following scheme:
[0005] The adjustable handle positioning and pushing device of the bag making machine includes a pushing chain, and a pushing platform is arranged below the pushing chain, which is characterized in that: an L-shaped pushing piece is rotatably arranged on the pushing chain, and an elastic reset piece is arranged corresponding to the pushing piece, and an extrusion plate is arranged above the bottom end of the pushing chain, and the extrusion plate is slidably arranged on the mounting frame and locked by a locking assembly. When the pushing chain drives the pushing piece to move and contact with the extrusion plate, the extrusion plate will squeeze the pushing piece and rotate to the pushing angle, so that the pushing part on the pushing piece swings downward to push the handle, and when the pushing piece is separated from the extrusion plate, the elastic reset piece drives the pushing piece to rotate so that the pushing part swings upward.
[0006] The elastic reset member is a torsion spring, and the torsion spring can drive the pushing member to rotate so that the pushing portion swings upward.
[0007] The extrusion plate is provided with a strip groove, and the fastener passes through the strip groove and is screwed to the mounting frame to lock the extrusion plate on the mounting frame.
[0008] The mounting frame is liftably arranged on the fixing frame. An adjusting screw is rotatably arranged on the fixing frame. The adjusting screw is threadedly connected to the mounting frame.
[0009] The adjustable handle positioning and pushing device of the bag making machine of the above technical solution realizes the rotation of the pushing piece by setting an extrusion plate and cooperating with the pushing piece, so that the pushing part on the pushing piece swings downward to push the handle, and cooperates with an elastic reset piece to drive the pushing piece to reset and rotate so that its pushing part swings upward and separates from the handle. By adjusting the position of the extrusion plate and changing the separation position of the extrusion plate and the pushing piece, the separation position of the pushing piece and the handle can be adjusted, thereby adapting to the positioning and pushing of handles of different specifications.

[0014] As shown in the figure, the adjustable handle positioning and pushing device of the bag making machine disclosed by the present invention includes a pushing chain 7, a pushing platform 1 is provided below the pushing chain 7, an L-shaped pushing member 9 is rotatably provided on the pushing chain 7, and an elastic reset member is provided corresponding to the pushing member 9. In this embodiment, the elastic reset member is a torsion spring 10, which can drive the pushing member 9 to rotate so that the pushing portion 8 swings upward. Of course, the elastic reset member can also be a spring, one end of the spring is connected to the pushing member 9, and the other end is connected to the pushing chain 7. An extrusion plate 2 is provided above the bottom end of the pushing chain 7. The extrusion plate 2 is slidably provided on the mounting frame 4 and is locked by a locking assembly. Specifically, a strip groove 3 is provided on the extrusion plate 2, and a fastener passes through the strip groove 3 and is screwed to the mounting frame 4 to lock the extrusion plate 2 to the mounting frame 4. By loosening the fastener, the extrusion plate 2 is controlled to move forward and backward, and then the fastener is passed through the strip groove 3 and screwed to the mounting frame 4 to fix the extrusion plate 2. When the push chain 7 drives the pusher 9 to move to contact with the extrusion plate 2, the extrusion plate 2 will squeeze the pusher 9 and rotate it to the pushing angle, so that the pusher portion 8 on the pusher 9 swings downward to push the handle. When the pusher 9 is separated from the extrusion plate 2, the elastic reset member drives the pusher 9 to rotate so that the pusher portion 8 swings upward. Furthermore, the mounting frame 4 is arranged on the fixed frame 5 in a liftable manner. The fixed frame 5 is rotatably provided with an adjusting screw 6. The adjusting screw 6 is screwed to the mounting frame 4. By controlling the rotation of the adjusting screw 6, the mounting frame 4 and the extrusion plate 2 can be driven to move up and down, and the height of the extrusion plate 2 can be adjusted, so that the angle at which the extrusion plate 2 squeezes the pusher 9 can be adjusted, ensuring that the pusher 9 can be rotated to a suitable angle and thus stably push the handle to move on the pushing platform 1.
[0015] The working principle of the present utility model is as follows: the handle is sent to the pushing platform 1, and then the pushing chain 7 drives the pushing piece 9 to move to the right side of the extrusion plate 2, the extrusion part 11 on the pushing piece 9 is squeezed by the extrusion plate 2, and the pushing piece 9 is rotated, and the pushing part 8 on the pushing piece 9 swings downward and is against the handle on the pushing platform 1. As the pushing chain 7 continues to move, the pushing part 8 pushes the handle to the subsequent bonding station, and when the pushing piece 9 is separated from the extrusion plate 2, the elastic reset part will drive the pushing piece 9 to reverse and reset, and the pushing part 8 swings up and separates from the handle. By adjusting the front and rear position of the end of the extrusion plate 2, the positioning of the final pushing position of the handle can be achieved, which is suitable for handles of different specifications.
[0016] The structure of the present invention realizes the rotation of the pushing piece by arranging an extrusion plate to cooperate with the pushing piece, thereby making the pushing part on the pushing piece swing downward to push the handle, and is cooperated with an elastic reset piece to drive the pushing piece to reset and rotate so that its pushing part swings upward and separates from the handle. By adjusting the position of the extrusion plate and changing the separation position of the extrusion plate and the pushing piece, the separation position of the pushing piece and the handle can be adjusted, thereby adapting to the positioning and pushing of handles of different specifications.
