Description

Technical Field

[0001] This utility model relates to the field of labeling technology, specifically to a bottle inlet screw adjustment component for a labeling machine. Background Technology

[0002] Traditional bottle feeding screw devices have internal and external adjustment components, which can adjust the distance between the screw and the bottle body according to the bottle diameter to adapt to bottle shapes of different diameters. However, the distance between the center of the screw and the bottom of the bottle in traditional bottle feeding screw devices is generally 60 to 70 mm, and the height is fixed. This means that when the center of gravity of a shorter or taller bottle changes, the screw is prone to causing the bottle to tilt forward or backward when separating the bottles, thus affecting normal production. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bottle inlet screw adjustment component for a labeling machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0006] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0007] A screw jack can be used to adjust the height of bottles by using a lifting base and a motor support to drive the bottle-feeding screw device, thereby adapting to bottles of different heights and preventing the bottles from tilting forward or backward.

[0008] As a preferred embodiment, a further technical solution of this utility model is:

[0009] Preferably, the fixed base has a gate-shaped structure, the screw jack is placed in the fixed base, and the screw jack's lead screw extends upward through the fixed base.

[0010] Preferably, the guiding mechanism includes guide rods vertically arranged on both sides of the screw of the screw jack, guide sleeves slidably fitted on the guide rods, and mounting holes adapted to the guide rods on the lifting seat, with the guide sleeves placed in the mounting holes and fixed to the lifting seat.

[0011] Preferably, the sliding mechanism includes two horizontally opposite sliding rods, each sliding rod is provided with two sliders, two adjacent sliders on the two sliding rods form a group, a support plate is connected between each group of sliders, and the motor support is fixed on the support plate.

[0012] Preferably, each slider is provided with a threaded hole, and a screw is provided in the threaded hole, and the screw can abut against the slider.

[0013] Preferably, the motor support includes a vertically arranged fixed shaft, a shaft sleeve is rotatably sleeved on the fixed shaft, and a support plate is provided at the top of the shaft sleeve.

[0021] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0022] like Figures 1 to 5As shown in the figure, this embodiment provides a bottle feeding screw adjustment assembly for a labeling machine, including a fixed base 1, a screw lift 2 disposed in the fixed base 1, a lifting seat 4 disposed on the lead screw nut 3 of the screw lift 2, a guide mechanism 5 disposed on the fixed base 1 and slidingly engaging with the lifting seat 4, a sliding mechanism 6 disposed on the lifting seat 4, two motor supports 7 opposite each other on the sliding mechanism 6, a bottle feeding screw device 8 mounted on the top of the motor supports 7, and an inner and outer adjustment assembly 9 disposed between the middle of the two motor supports 7.

[0023] In practice, the fixed base 1 has a gate-shaped structure, the screw jack 2 is placed in the fixed base 1, and the screw jack 10 of the screw jack 1 extends upward through the fixed base 1.

[0024] The guiding mechanism 5 includes guide rods 11 vertically arranged on both sides of the screw 10 of the screw jack 2. Guide sleeves 12 are slidably fitted on the guide rods 11. The lifting seat 4 has mounting holes adapted to the guide rods 11. The guide sleeves 12 are placed in the mounting holes and fixed to the lifting seat 4.

[0026] Each slider 14 is provided with a threaded hole, and a screw 16 is provided in the threaded hole. The screw 16 can be pressed against the slide rod 13. The distance between the screw and the bottle body can be adjusted according to the bottle diameter by sliding the slider 14 on the slide rod 13, and then the screw 16 is used to lock and fix it.
