Abstract

The utility model discloses a guiding device or a paper feeding device of a paper cutting machine. A shell body of the paper feeding device of the utility model, a left connecting plate, a right connecting plate, a force transferring beam are formed into a rectangular rigid frame which transversely surrounds a workbench for one circle, wherein the left connecting plate and the right connecting plate are arranged on both sides of the shell body, and the force transferring beam is positioned below the workbench. One linear guide rail which is extended along the moving direction of the paper feeding device is fixedly arranged on the surface of the workbench, wherein at least one linear slider which is in sliding fit with the guide rail is installed on the guide rail. Fixed connection is formed between the linear slider and the force transferring beam, and the force transferring beam is driven by a straight line reciprocatingly moving mechanism which acts on the force transferring beam. The utility model has the advantages that the linear slider on the linear guide rail limits the upper, the lower, the left and the right degrees of freedom of the paper feeding device of the paper cutting machine. Therefore, an error which is caused by the disalignment of two guide rails to the paper feeding device can be avoided to increase the operational accuracy of the paper feeding device. Since a groove does not need to be arranged in the middle of the workbench, the rigidity and the strength of the workbench are increased.

Description

The paper pulling device of paper cutter guider

Technical field

The utility model relates to the feeder in the paper cutter, relates in particular to the guider of feeder.

Background technology

The feeder of existing paper cutter all moves on workbench, its motion is had plenty of by the elongated slot in the middle of the workbench, by force-transmitting block by the screw mandrel transmission under the workbench, the guide rail guiding, guide rail and screw mandrel place respectively near the both sides under the elongated slot, because structural limitations causes the middle fluting of workbench, has reduced the strength and stiffness of workbench.Though the motion of some paper pulling device of paper cutter is by a horizontal Rectangular Rigid framework transmission around one week of workbench, lead by parallel two linear guides that are fixed under the workbench, because the linear slide block on each root linear guides has limited four frees degree in upper and lower, left and right, again that the rigid frame of two linear guides and rectangle is affixed, the guiding mechanism that causes feeder was a location structure.Because in reality processing and assembling process, two parallel linear guides can not be parallel to each other fully, make feeder in the process of front and back operation, can't compensate because of two not parallel errors of bringing of guide rail, cause the two ends of feeder its working face in running can not be synchronous, thereby bring the error that can't remedy to complete machine.

The utility model content

Technical problem to be solved in the utility model provides a kind of paper pulling device of paper cutter guiding and puts, and this device can not only improve the running precision of feeder, and the rigidity of paper cutter workbench and intensity are greatly improved.

The technical scheme that its technical problem that solves the utility model adopts is: paper pulling device of paper cutter guider of the present utility model, the left connecting plate of its feeder housing and both sides, right connecting plate (22) and the transfer beam that is positioned at workbench below constitute horizontal Rectangular Rigid framework around one week of workbench, it is characterized in that: be set with a linear guides that extends along the feeder direction of motion on the described workbench lower surface; The linear slide block that at least one is slidingly matched with it is installed on the linear guides, forms a fixed connection between this linear slide block and the described transfer beam; Transfer beam is driven by the linear reciprocating mechanism that is applied to it.

The beneficial effects of the utility model are, four frees degree in upper and lower, left and right of paper pulling device of paper cutter have been limited by the linear slide block on the single line guide rail, can avoid bringing error for the motion of feeder, thereby improve the running precision of feeder because of two guide rails are not parallel; Need not slot in the middle of the workbench, can improve the rigidity and the intensity of workbench greatly.

Description of drawings

This specification comprises following two width of cloth accompanying drawings:

Fig. 1 is the structural representation of the utility model paper pulling device of paper cutter guider;

Fig. 2 is the local enlarged diagram of the utility model paper pulling device of paper cutter guider structure.

Parts, position and numbering among the figure: workbench 10, linear guides 11, slide block 12, pressing board 13, feeder housing 20, left connecting plate 21, right connecting plate 22, transfer beam 23, Connection Block 24, screw mandrel 30.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Figure 1, paper pulling device of paper cutter guider of the present utility model, left connecting plate 21, the right connecting plate 22 of its feeder housing 20 and both sides and the transfer beam 23 that is positioned at workbench 10 belows constitute horizontal Rectangular Rigid framework around one week of workbench.On workbench 10 lower surfaces, be set with a linear guides 11 that extends along the feeder direction of motion.At least one linear slide block that is slidingly matched with it 12 is installed on the linear guides 11, forms a fixed connection between this linear slide block 12 and the transfer beam 23.In order to increase the guiding rigidity and the intensity of linear guides 11, a plurality of linear slide blocks 12 can be installed simultaneously thereon.Limited four frees degree in paper pulling device of paper cutter upper and lower, left and right by the linear slide block on the single line guide rail, can avoid bringing error for the motion of feeder, thereby improved the running precision of feeder because of two guide rails are not parallel.Need not slot in the middle of the workbench 10, can improve its rigidity and intensity greatly.

Transfer beam 23 is driven by the linear reciprocating mechanism that is applied to it.Described linear reciprocating mechanism can adopt screw mandrel nut mechanism, hydraulic mechanism, pinion and rack etc.For guaranteeing the running precision of feeder, reduce the wearing and tearing of linear guides 11 and each moving component as far as possible, the center line of linear guides 11 should coincide with the center line of workbench 10.

Linear slide block 12 can be directly fixed on the transfer beam 23, also can fixedly install Connection Block 24 in transfer beam 23, and linear slide block 12 is fixedly connected on this Connection Block 24.As shown in Figure 2, when adopting leading screw and nut mechanism to drive feeder, screw mandrel 30 passes Connection Block 24, and nut is then fixedlyed connected with Connection Block 24.

It is pointed out that top described principles more of the present utility model that just explain through diagrams, because the those of ordinary skill in constructed field is easy to carry out on this basis some modifications and change.Therefore, this specification be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
