Detailed Description
For the purpose of facilitating understanding, the present invention will be described in detail below with reference to the accompanying drawings.
The utility model provides a cut card machine pickup roller, includes cylindric pickup roller body 10, coaxial mounting hole 11 that runs through that is equipped with on the pickup roller body 10, the laminating is equipped with elasticity pickup roller skin 20 on the wheel face of pickup roller body 10, for the joint cooperation between pickup roller skin 20 and the pickup roller body 10, both guaranteed that the laminating of pickup roller skin 20 is fixed on pickup roller body 10, avoided the various problems that glue bonding mode produced again, the mode of joint connection between pickup roller skin 20 and the pickup roller body 10 makes pickup roller skin 20's dismouting more convenient simultaneously, improves user experience. The paper twisting wheel body 10 penetrates through the mounting hole 11 and is arranged on a rotating shaft at a paper inlet of the card cutting machine, a paper twisting wheel skin 20 outside the paper twisting wheel body 10 is pressed on the surface of paper, the rotating shaft drives the paper twisting wheel body 10 to rotate, the paper advances under the pushing of the paper twisting wheel skin 20, and the paper feeding of the card cutting machine is completed.
A clamping groove 12 with a notch pointing outwards is arranged on the wheel surface of the paper rolling wheel body 10, and the clamping groove 12 is in a closing shape with a large groove cavity and a small notch; the paper twisting wheel leather 20 is provided with a lug 21 matched with the clamping groove 12, and the lug 21 is inserted into the clamping groove 12. Specifically, the section of the groove cavity of the clamping groove 12 is circular, the section of the lug 21 is circular matched with the circular, the clamping fit is formed between the groove cavity and the lug, the elastic paper rolling wheel leather 20 is in a stretching state on the wheel surface of the paper rolling wheel body 10, and the paper rolling wheel leather 20 is ensured to be tightly attached to the wheel surface of the paper rolling wheel body 10.
As shown in fig. 1, 2 and 3, the groove length direction of the clamping grooves 12 is the same as the axial direction of the paper rolling wheel body 10, and two groups of clamping grooves 12 are arranged at intervals along the circumferential direction of the paper rolling wheel body 10; the two groups of lugs 21 are arranged at two ends of the paper rolling wheel leather 20, and the length direction of the lugs 21 is consistent with the axial direction of the paper rolling wheel body 10. The lugs 21 arranged at the two ends of the paper rolling wheel skin 20 are clamped in the two clamping grooves 12, so that the paper rolling wheel body 10 is divided into a paper rolling arc section with the paper rolling wheel skin 20 and a static arc section without the paper rolling wheel skin 20, and the paper rolling arc section is a working section for pushing paper to advance by the paper rolling wheel skin 20 on the paper rolling wheel body 10 when the paper rolling wheel body 10 rotates along with the rotating shaft; the static arc section is that when the pickup roller body 10 rotates along with the rotating shaft, the pickup roller leather 20 on the pickup roller body 10 does not push paper, and the paper is static relative to the paper inlet of the card cutter.
In another embodiment, the two slots 12 may also be arranged such that the slots 12 are arranged along the circumferential direction of the pickup roller body 10 and have the same radian, and the two slots 12 are arranged along the axial direction of the pickup roller body 10 and are respectively disposed at two edges (no view is shown); the two lugs 21 are arranged along two side edges of the paper rolling wheel leather 20.
Because the paper pickup wheel is sleeved on the rotating shaft, the rotating shaft is arranged on the card cutting machine, when the paper pickup wheel needs to be replaced, the paper pickup wheel needs to be taken down from the rotating shaft, and in order to facilitate the disassembly and assembly of the paper pickup wheel on the rotating shaft, a notch 13 which penetrates along the axial direction is arranged between the two clamping grooves 12 on the paper pickup wheel body 10, the notch 13 radially extends from the wheel surface of the paper pickup wheel body 10 to be communicated with the mounting hole 11, the width size of the notch 13 is convenient for the paper pickup wheel body 10 to be arranged on the rotating shaft through the notch 13, the paper pickup wheel body 10 can synchronously rotate along with the rotating shaft, and the paper pickup wheel skin 20 is positioned at the position of avoiding the notch 13. The setting of breach 13 on the pickup roller body 10 need not to dismantle the pivot and can realize the dismouting of pickup roller in the pivot, when pickup roller skin 20 need be changed, or pickup roller body 10 need be changed, pulls the pickup roller, and the pivot shifts out from breach 13, can realize the dismouting, and the width of breach 13 has following several kinds of implementation modes: firstly, the width of the gap 13 is consistent with the diameter of the mounting hole 11, the mounting hole 11 of the paper rolling wheel body 10 is just mounted on the rotating shaft, and the paper rolling wheel body 10 can synchronously rotate along with the rotating shaft; secondly, the width of the notch 13 is slightly smaller than the diameter of the mounting hole 11, and because the paper rolling wheel body 10 is made of plastic, the notch 13 has slight elasticity, and the rotating shaft can enter the mounting hole 11 through the notch 13; thirdly, the width of the notch 13 is slightly larger than the diameter of the mounting hole 11, but has no influence on the synchronous rotation of the paper wheel body 10 along with the rotating shaft.
