Description

Technical Field

[0001] The utility model relates to the technical field of medical paper plastic bag production, in particular to a winding roller for fixing a medical paper plastic bag substrate. Background Art

[0002] Paper-plastic bags, also known as three-in-one composite paper bags, are made of a compound of plastic and kraft paper. Usually, the plastic layer uses pp silk woven cloth with polypropylene as the base material, and the kraft paper uses refined composite special kraft paper. The two are bonded by hot laminating molten plastic. The kraft paper coated cloth is formed into bags and then processed and sewn into three-in-one paper-plastic bags.

[0003] During the production process of paper-plastic bags, the rolled paper substrate needs to be unwound and rewound multiple times. Since the winding tubes for winding the paper substrate are not uniform in size, the winding roller needs to meet the needs of fixing winding tubes of different sizes and prevent the fixed winding tubes from shaking left and right during rotation, so that the substrate can be transported straight during the processing. Utility Model Content

[0004] The utility model aims to solve the defects in the prior art and provides a winding roller for fixing a medical paper plastic bag substrate.

[0005] The utility model is achieved through the following technical solutions:

[0006] A winding roller for fixing a medical paper plastic bag substrate comprises a transmission rod, a cylinder seat, a cylinder, a support assembly and a locking seat, wherein the cylinder seat is fixedly arranged on the outside of one end of the transmission rod, the cylinder is installed on the outside of the cylinder seat, the support assembly is sleeved on the outside of the transmission rod, and the locking seat is clamped on the outside of the top of the support assembly, the support assembly comprises a fixed ring, a movable ring, a connecting plate, a support rod, a mounting seat, an inner support bar and a contact plate, the fixed ring is fixedly arranged on the outside of the transmission rod, the movable ring is sleeved on the outside of one end of the transmission rod, the connecting plate is fixedly arranged on the outside of the fixed ring and the movable ring, the support rod is movably connected to the connecting plate, the mounting seat is movably arranged on one end of the support rod, the inner support bar is fixed to the top of the mounting seat, and the contact plate is fixedly arranged on the outside of the movable ring.

[0007] In a preferred embodiment of the present invention, one end of the oil cylinder penetrates and extends to the outside of one side of the oil cylinder seat, and its telescopic end is fixed to the outside of the contact plate;

[0008] The oil cylinder drives the movable ring to move left and right to change the support angle of the support rod to the mounting seat, thereby controlling the height of the inner support bar and making the inner support bar fit the inner wall of the substrate winding tube to achieve a fixing effect.

[0009] In a preferred embodiment of the present invention, the locking seat is clamped on the top of the inner support, a sliding groove that cooperates with the inner support is opened on the inner side of the bottom of the locking seat, and a locking screw is provided on the side of the locking seat, and the end of the locking screw on the side of the locking seat contacts the side of the inner support;

[0010] The main function of the locking seat is to fix the two ends of the winding tube after the inner support bar is propped up inside the winding tube, effectively preventing the winding tube from moving left and right during the rotation of the transmission rod and affecting the winding or unwinding of the substrate.

[0011] In a preferred embodiment of the present invention, the top of the inner support bar is inclined, and an anti-slip groove is provided on its upper surface;

[0012] The anti-slip groove improves the fixing effect of the winding tube and better enables the inner support bar to fit the inner wall of the winding tube.

[0013] In a preferred embodiment of the present invention, the support rod is movably connected to the mounting seat and the connecting plate via a pin, and a slot is provided at one end of the support rod to cooperate with the mounting seat;

[0014] The card slot at the end of the support rod mainly provides sufficient space during the adjustment process of the mounting seat and the connecting plate to avoid interference between the support rod, the mounting seat and the connecting plate.

[0015] The beneficial effects of the utility model are:

[0016] The winding roller for fixing the medical paper plastic bag substrate can adjust the position of the support bar according to the inner diameter of the winding tube used for winding the substrate, ensuring that the winding tube and the transmission rod are arranged concentrically. The winding tube is easy to install and reliably fixed. The locking seats on the surface of the inner support bar effectively limit the two ends of the winding tube, thereby ensuring that the substrate will not be offset or creased during winding and unwinding.

[0022] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0023] like Figure 1-4 The shown winding roller for fixing a medical paper plastic bag substrate includes a transmission rod 1, a cylinder seat 2, a cylinder 3, a support assembly 4 and a locking seat 5. The cylinder seat 2 is fixedly arranged on the outside of one end of the transmission rod 1, the cylinder 3 is installed on the outside of the cylinder seat 2, the support assembly 4 is sleeved on the outside of the transmission rod 1, and the locking seat 5 is clamped on the outside of the top of the support assembly 4. The support assembly 4 includes a fixed ring 41, a movable ring 42, a connecting plate 43, a support rod 44, a mounting seat 45, an inner support bar 46 and a contact plate 47. The fixed ring 41 is fixedly arranged on the outside of the transmission rod 1, the movable ring 42 is sleeved on the outside of one end of the transmission rod 1, the connecting plate 43 is fixedly arranged on the outside of the fixed ring 41 and the movable ring 42, the support rod 44 is movably connected to the connecting plate 43, the mounting seat 45 is movably arranged at one end of the support rod 44, the inner support bar 46 is fixed to the top of the mounting seat 45, and the contact plate 47 is fixedly arranged at one end outside the movable ring 42.

[0024] Specifically, one end of the oil cylinder 3 passes through and extends to the outside of one side of the oil cylinder seat 2, and its telescopic end is fixed to the outside of the contact plate 47. The locking seat 5 is clamped on the top of the inner support bar 46. The inner side of the bottom of the locking seat 5 is provided with a sliding groove that cooperates with the inner support bar 46. A locking screw is provided on the side of the locking seat 5. The end of the locking screw on the side of the locking seat 5 contacts the side of the inner support bar 46. The top of the inner support bar 46 is inclined, and an anti-slip groove is provided on its upper surface. The support rod 44 is movably connected to the mounting seat 45 and the connecting plate 43 through a pin shaft, and a slot that cooperates with the mounting seat 45 is provided at one end of the support rod 44.

[0025] In this embodiment, when the substrate winding tube is installed, the cylinder 3 is first in a retracted state. At this time, the cylinder 3 drives the movable ring 42 to move backward. Under the pull of the support rod 44, the inner support bar 46 falls, so that the winding tube is sleeved on the outside of the support assembly 4. After the winding tube is sleeved at a predetermined position, the cylinder 3 on the outside of the cylinder seat 2 extends, so that under the forward push of the contact plate 47, the movable ring 42 moves forward, so that the angle formed by the support rod 44 and the transmission rod 1 changes, and the support rod 44 supports the bottom mounting seat 45 of the inner support bar 46, so that the top of the inner support bar 46 is effectively fitted with the inner wall of the winding tube. Since the top of the inner support bar 46 is inclined and provided with an anti-slip groove, the supporting and fixing effect of the inner support bar 46 on the inner wall of the winding tube is effectively guaranteed.

[0026] Furthermore, in order to prevent the risk of the fixed winding tube shaking left and right due to the driving motor driving the transmission rod 1 to rotate during use, thereby causing the risk of the substrate being wound or unwound to be offset or creased, it is necessary to set a locking seat 5 at both ends of the fixed winding tube. The locking seat 5 is movably connected to the inner support bar 46 through the sliding groove at the bottom. After sliding the locking seat 5 to the two ends of the winding tube, tighten the locking screws on both sides of the locking seat 5 so that the ends of the screws are in close contact with both sides of the inner support bar 46 to achieve a fixing effect, effectively avoiding the rotating winding tube from shaking left and right, and ensuring the winding and releasing effect.
