Abstract
Provided is a low-noise error correction device of a needle printer. The device comprises a front upper paper transporting assembly, a front lower error correction assembly, and a lower paper supporting frame. The front upper paper transporting assembly comprises a paper transporting frame, a plurality of rollers and a plurality of corresponding compressed springs. The front upper paper transporting assembly is installed above the lower paper supporting frame, and a paper feeding channel is formed between the front upper paper transporting assembly and the lower paper supporting frame. The front lower error correction assembly is installed under the lower paper supporting frame, that is, the front lower error correction assembly is installed under the paper feeding channel. The front lower error correction assembly comprises a plurality of triangular error correction rollers, and width of the error correction roller is lower than width of the roller in the front upper paper transporting assembly, and the error correction rollers align with the roller in a central manner. An axial direction of the roller is designed in three-section type. The section on the center is provided with a slotting whose width is larger than that of the error correction roller, thereby preventing direct contact with the error correction roller, and noise in error correction is greatly reduced. The low-noise error correction device is suitable for the needle printer. In error correction, the rollers and the error correction rollers do not directly contact. Through a simple structure, noise in error correction is greatly reduced. The low-noise error correction device is simple in structure and low in cost.
Description
Technical field:
The utility model relates to a kind of error-correction structure that is applicable to a kind of low noise of impact printer.
Background technology:
Impact printer belongs to office equipment, when meeting increasing functional requirement, to noise, requires also more and more higher.
Utility model content:
The purpose of this utility model is to provide a kind of deviation correcting device of low noise of impact printer, is applicable to impact printer.
The technical solution of the utility model is achieved in that the deviation correcting device of the low noise of impact printer, it is characterized in that comprising front upper defeated paper assembly, front lower correction assembly, lower paper support, front upper defeated paper assembly comprises defeated paper frame, several rollers and corresponding stage clip, front upper defeated paper assembly is arranged on the top of lower paper support, and forms paper feed passage between lower paper support; Front lower correction assembly is arranged on the below that lower paper support is paper feed passage, comprises several leg-of-mutton deviation rectification rollers, and the width of deviation rectification roller is less than the roller width in front upper defeated paper assembly, and with roller align center; The axial design of described roller becomes three-section type, and a middle joint has the fluting that is greater than deviation rectification roller width; Can avoid contacting with the direct of deviation rectification roller the noise while greatly reducing correction.The utility model is applicable to impact printer.
Further, front lower correction assembly is through on axle by several triangle deviation rectification rollers, and deviation rectification roller width is less than the width of the middle joint of roller.
Further, roller and deviation rectification roller align center, when correction, roller and deviation rectification roller have interval; And not directly contact.
The beneficial effects of the utility model are: when correction, roller does not directly contact with deviation rectification roller.By simple frame mode, the noise while greatly reducing correction, simple in structure, with low cost.

Fig. 4 is the 3D topology view of low noise correction mode;
Fig. 5 is the side view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1,2,3,4, this deviation correction mechanism is mainly comprised of following parts: 1 defeated paper frame, 2 rollers, 3 stage clips, 4 axles, 5 deviation rectification rollers, 6 times paper supports.
Fig. 1 is the front view of front upper defeated paper assembly.Front upper defeated paper assembly is comprised of defeated paper frame 1, some rollers 2 and corresponding stage clip 3.As figure, stage clip 3 is contained on defeated paper frame, and the corresponding stage clip 3 of roller 2 snaps in the draw-in groove of defeated paper frame 1, the corresponding stage clip 3 of each roller 2, and when this contacts some rollers 2 simultaneously or separately with paper, the correction power of each roller 2 is consistent.
Fig. 2 a is the detailed view of roller 2.2b is the side view of Fig. 2 a.As figure, the structure of roller 2 is for being axially divided into three joints, centre is that width is the fluting of D, two ends are one section of face of cylinder that diameter is identical, the face of cylinder contacts with paper while rectifying a deviation, and guarantees required correction power, and wherein D is greater than the width of deviation rectification roller 5, avoid directly contacting with deviation rectification roller 5, greatly reduce correction noise.
Fig. 3 is the 3D view of front lower correction assembly.Some deviation rectification rollers 5 are all contained on axle 4, form front lower correction assembly.Deviation rectification roller 5 is designed to triangle, and the width of deviation rectification roller 5 is less than D, and when correction, deviation rectification roller 5 rotates jointly with the roller 2 in front upper defeated paper assembly like this, drives paper to advance.
Fig. 4 is the 3D topology view of low noise correction mode, and as figure, front upper defeated paper assembly is arranged on the top of lower paper support 6, forms paper feed passage with lower paper support 6; Front lower correction assembly is arranged on the below of lower paper support 6, deviation rectification roller 5 and roller 2 align centers.
When printer paper feed, front lower correction assembly rotates, roller 2 actings in conjunction in deviation rectification roller 5 and front upper defeated paper assembly, but directly contact produces frictional force forward, drives paper to advance.
As mentioned above, according to the utility model structure, when obtaining reliable rectifying effect, the noise while also greatly reducing correction, simple in structure, with low cost.
Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Under the utility model, in technical field, have and conventionally know the knowledgeable, within not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on claims person of defining.
