Background technique

Paper containers have the advantages of convenient use, safety and hygiene, and are more environmentally friendly than plastic containers. They are being used in more and more fields. The bottom press is a device used to press and seal the cup and bottom of the paper container. Existing bottom pressers are all suitable for cylindrical paper containers, which use a rolling bottom inner mold to perform planetary movement along the inner cavity of the bottom rolling outer mold, thereby pressing the paper container cup body and bottom to seal the bottom. The bottom presser of this structure is not suitable for the bottom cover of the square paper container with a square inner cavity of the outer mold for rolling the bottom.

Utility model content

The utility model provides a rolling bottom type bottom presser.

The purpose of this utility model is to solve the problem that the existing bottom presser structure is only suitable for cylindrical paper containers, but not suitable for the bottom sealing of square paper containers with a square inner cavity of the outer mold for rolling the bottom.

The technical scheme adopted by the utility model to solve the technical problem is: a rolling bottom presser, including a knurled outer mold base, an inner spline sleeve, a lifting mechanism, and a rotating mechanism. There is a knurled outer mold, the inner spline sleeve is provided with a large gear middle cylinder, the large gear middle cylinder is provided with a slider and a slider sleeve, and a slider is provided between the slider and the slider sleeve Spring, the upper side of the slider is provided with a knurling wheel, and the lower side is provided with a thimble wheel, the knurling wheel corresponds to the position of the knurling outer mold, and a large spline shaft is inserted in the inner spline sleeve. A large spline shaft spring is arranged between the large spline shaft and the inner spline sleeve, the upper end of the large spline shaft corresponds to the position of the thimble wheel, the lower end is connected with the lifting mechanism, and the rotating mechanism is connected with the small spline shaft. The small spline shaft is connected with the middle cylinder of the large gear through a gear.

Preferably, a dustproof cover is provided above the slider.

Preferably, the large spline shaft is provided with an oil injector.

Preferably, the inner cavity of the knurled outer mold has a rounded square structure, the upper end of the large spline shaft has a slope groove structure, and the outer side of the ejector pin wheel section has a slope structure.

The beneficial effects of the utility model are: the rolling bottom presser described in the utility model makes the knurling wheel and the knurling outer mold squeeze the paper through the inclined surface groove structure at the upper end of the large spline shaft, and rotates the middle cylinder of the large gear Make the knurling wheel roll around along the knurling outer mold to complete the bottom cover of the square paper container. The utility model overcomes the deficiency that the existing planetary bottom presser can only be used for sealing the bottom of a cylindrical paper container, and can be used for bottom sealing of a square paper container with a square inner cavity of a rolling bottom outer mold.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in the figure, an embodiment of the rolling bottom presser of the present invention is provided, including a knurled outer mold base 2, an inner spline sleeve 5, a lifting mechanism, and a rotating mechanism. The knurled outer mold base 2 is provided with There is a knurled outer mold 1, the inner spline sleeve 5 is provided with a large gear middle cylinder 7, and the large gear middle cylinder 7 is provided with a slider 15 and a slider cover 9, and the slider 15 and the slider A slider spring 10 is arranged between the sleeves 9, the upper side of the slider 15 is provided with a knurling wheel 12, and the lower side is provided with a thimble wheel 14, and the knurling wheel 12 corresponds to the position of the knurling outer mold 1. The inner spline sleeve 5 is inserted with a large spline shaft 6, a large spline shaft spring 8 is arranged between the large spline shaft 6 and the inner spline sleeve 5, and the upper end of the large spline shaft 6 is connected to the thimble wheel 14 Corresponding positions, the lower end is connected with the lifting mechanism, the rotating mechanism is connected with the small spline shaft 3, and the small spline shaft 3 is connected with the middle cylinder 7 of the large gear through the gear 4.

A dustproof cover 11 is arranged above the slider 15 .

The large spline shaft 6 is provided with an oil injector 13 .

The inner cavity of the knurled outer mold 1 has a square structure with rounded corners, the upper end of the large spline shaft 6 has a slope groove structure, and the outer side of the ejector pin wheel 14 has a slope structure.

Its working principle is: the lifting mechanism drives the large spline shaft 6 to move upward, the upper end of the large spline shaft 6 is in contact with the thimble wheel 14, and the slope groove structure at the upper end of the large spline shaft 6 pushes the thimble wheel 14 to move, driving the slider 15 Move to drive the knurling wheel 12 to move and compress the knurling outer mold 1, which is used to compress the paper sheets. The rotating mechanism drives the small spline shaft 3 to rotate, thereby driving the middle barrel 7 of the large gear to rotate through the gear 4, and finally drives the slider 15 and the knurled wheel 12 to rotate, and the knurled wheel 12 that has pressed the paper sheet rotates with the slider 15 And roll around along the inner cavity of the knurled outer mold 1, so as to realize the sealing of the bottom of the paper container.

The rolling bottom presser described in the utility model makes the knurling wheel and the knurling outer mold squeeze the paper through the inclined groove structure at the upper end of the large spline shaft, and the knurling wheel is rotated along the knurling outer The mold is rolled around to complete the bottom cover of the square paper container. The utility model overcomes the deficiency that the existing planetary bottom presser can only be used for sealing the bottom of a cylindrical paper container, and can be used for bottom sealing of a square paper container with a square inner cavity of a rolling bottom outer mold.
