Description

Technical Field

[0001] The utility model relates to the field of industrial printers, in particular to a paper placing weight adjustment component and an industrial printer. Background Art

[0002] Digital industrial printers are devices that print patterns on textile fabrics. Compared with traditional printing equipment, digital industrial printers have many advantages, such as small footprint, high degree of automation, less labor, low energy consumption and high efficiency. They are widely used in clothing, home furnishing fabrics, sampling, T-shirts, canvas bags, cushions, scooters, flags, textile fabrics, etc. Existing digital industrial printers mainly use U-shaped tension rollers to keep the printing medium tensioned, but the U-shaped tension roller can only be used as a constant tension roller and cannot adjust the tension it can provide.

[0003] The utility model patent with the authorization announcement number CN218057634U discloses an adjustable tension swing roller for a digital printing printer, including a swing roller body, a rotating roller and a counterweight roller, which are arranged side by side, and a swing frame is arranged at both ends of the three roller bodies; the swing roller body and the rotating roller are connected to the swing frame through a rotating shaft, and the rotating shafts at both ends of the rotating roller are provided with mounting shafts through the swing frame; the rotating roller is arranged between the swing roller body and the counterweight roller, the swing roller body and the rotating roller are arranged close to one end of the swing frame, the counterweight roller is arranged at the other end of the swing frame, and an adjustment slot is arranged on the swing frame, and a slider is installed at the end of the counterweight roller, and the slider is arranged in the adjustment slot and slides along the adjustment slot. The swing roller provided by the adjustable tension swing roller for the digital printing printer changes the center of gravity position of the overall structure by setting a counterweight roller, thereby changing the tension that the swing roller body can provide, and can better perform paper feeding and ensure the stability of printing. However, the adjustable tension swing roller has high requirements on the installation space size of the mechanism, and cannot accurately control the tension size. Utility Model Content

[0008] Based on the above, in order to accurately feedback the sliding position of the slider, a plurality of position sensors are vertically arranged on the printer stand, and the position sensors are located on one side of the slider.

[0009] Based on the above, in order to facilitate the replacement of counterweights of different weights, the counterweight is detachably connected to the chain via a movable bolt.

[0010] Based on the above, the length of the chain is greater than the vertical length of the bar-shaped hole.

[0011] Based on the above, a pair of cloth winding rollers are arranged on the top of the printer stand, and the pair of cloth winding rollers are symmetrically distributed on both sides above the tension roller.

[0012] The utility model also provides an industrial printer, which is equipped with the paper placing weight adjustment component.

[0013] The present invention has substantial features and progress over the prior art. Specifically, the paper placing counterweight adjustment component and the industrial printer provided by the present invention are slidably arranged on the printer vertical plate by cooperating the two ends of the tension roller through the slider and the slide rail, and the counterweight blocks are connected to the two ends of the tension roller through the cooperation of the chain and the sprocket. Thus, on the basis of the existing industrial printer structure, the weight of the tension roller itself and the weight of the counterweight block can be used to provide a stable tension to the printing medium, and the tension can be accurately controlled and adjusted according to the weight of the counterweight block and the weight of the tension roller.

[0014] Furthermore, the tension of the tension roller can be adjusted by replacing the size of the counterweight, and the replacement procedure is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
