Description

Technical Field

[0001] This utility model belongs to the field of metering and packaging technology, and in particular relates to a slide rail device for a feeding and metering mechanism of a packaging machine. Background Technology

[0002] With the improvement of economic and technological levels, the variety of industrial products has become more diverse. Some granular products need to have their filling capacity or weight controlled during packaging to ensure the weight of the packaged product.

[0003] Most existing packaging equipment for granular products directly moves the metering chamber. During the feeding process, the feeding channel needs to be closed first, and the metering chamber needs to be transferred to the discharge port for discharge. This results in slow production efficiency. Due to the low precision of the fit between the various components, granular products will scatter during the material transfer process, which not only wastes materials, but also affects the normal operation of the equipment if they accumulate in the long term.

[0004] Therefore, we need to design a slide rail device for the feeding and metering mechanism of a packaging machine to solve these problems. Utility Model Content

[0005] The problem to be solved by this utility model is to provide a slide rail device for the feeding and metering mechanism of a packaging machine.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] Example: Figures 1-4As shown, a slide rail device for a feeding and metering mechanism of a packaging machine includes a base 1, a mounting seat 3 connected to the base 1, a guide groove 17 provided on the mounting seat 3, a slider 8 provided in the guide groove 17, a feeding hole 11 provided on the slider 8, a support seat 4 provided above the slider 8, the support seat 4 being connected to the mounting seat 3, an installation groove 18 provided on the support seat 4 located above the feeding hole 11, a guide tube 7 provided in the installation groove 18, the free end of the guide tube 7 slidingly engaging with the slider 8, a rotating shaft 14 symmetrically arranged along the guide tube 7 in the installation groove 18, a pusher block 15 rotatably mounted on the rotating shaft 14, the pusher block 15 slidingly engaging with the slider 8, the contact surface between the pusher block 15 and the slider 8 being located between the guide tube 7 and the rotating shaft 14, a spring 16 also provided in the installation groove 18 between the guide tube 7 and the rotating shaft 14, the spring 16 being connected to the pusher block 15 and the inner wall of the installation groove 18 respectively.

[0027] Specifically, a push cylinder 10 is provided on the mounting base 3 on one side of the slider 8. The output end of the push cylinder 10 is connected to the slider 8. A discharge hole 12 is provided in the guide groove 17 on the other side of the slider 8. When the slider 8 slides back and forth along the guide groove 17, the feeding hole 11 will alternately connect with the discharge hole 12 and the guide pipe 7.

[0028] The discharge hole 12 is funnel-shaped, and the diameters at both ends of the discharge hole 12 are not less than the diameter of the feeding hole 11. The small opening end of the discharge hole 13 is fixedly connected to the discharge pipe 13.

[0029] Specifically, the top of the slider 8 located below the mounting groove 18 is provided with a slide groove 9, the feeding hole 11 is located in the slide groove 9, the free end of the guide tube 7 is inserted into the slide groove 9 and slides against the bottom surface of the slide groove 9, and the pusher block 15 slides against the inner wall of the slide groove 9.

[0030] Specifically, a hopper 6 is provided on the support base 4, the output end of the hopper 6 is located above the guide pipe 7, and the output end of the hopper 6 is connected to the bottom of the guide pipe 7.

[0031] The support base 4 is equipped with a insert frame 5, and the hopper 6 is connected to the support base 4 through the insert frame 5.

[0032] Specifically, a lifting cylinder 2 is fixedly installed on the base 1, and the mounting seat 3 is located at the output end of the lifting cylinder 2 and connected to the base 1 through the lifting cylinder 2.

[0033] The working process of this embodiment is as follows: When working, the granular products to be packaged are put into the hopper 6. After entering the hopper 6, the granular products will enter the guide tube 7 along the hopper 6. If the guide tube 7 is aligned with the upper feeding hole 11 of the slider 8, the granular products will fall into the feeding hole 11. If the granular products are not aligned with the feeding hole 11, the granular products will be blocked in the guide tube 7.

[0034] When the cylinder 10 extends to move the slider 8, the granular product will fall into the feeding hole 11 after the slider 8 moves, and move to the top of the discharge hole 12 under the action of the feeding hole 11. Then the granular product in the feeding hole 11 will fall into the discharge hole 12, and pass through the discharge hole 12 to enter the packaging bag or packaging box from the discharge pipe 13. Then the cylinder 10 will shorten to reset the slider 8, so that the feeding hole 11 on the slider 8 is aligned with the guide pipe 7 again.

[0035] As the feed hole 11 moves toward the discharge hole 12, the pusher block 15 on the side closer to the discharge hole 12 will push the granular product in the chute 9 to move as it slides along the chute 9. When the feed hole 11 moves toward the discharge hole 12 and then toward the guide tube 7, the granular product in the chute 9 will move along the chute 9 and will be blocked by the pusher block 15 on the side away from the discharge hole 12, thus preventing the granular product from spilling onto the equipment as it moves with the slider 8, which could cause equipment malfunction.

[0036] When there is a large amount of granular product in the chute 9, it will accumulate near the guide tube 7. Before the slider 8 moves to the feeding hole 11 and aligns with the guide tube 7, some of the granular product will fall into the feeding hole 11, reducing packaging loss and production costs.

[0037] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
