In an embodiment of the present utility model, described slide unit comprises a slide body, be provided with one on the described slide body and be used for the rotation hole that is connected with described Bidirectional-screw, the bottom of described slide body is provided with a guide holder, is provided with the guide pin bushing that is connected with described guide rod in the described guide holder.
Further, the top of described slide body is provided with a turning set, is provided with a wear-resistant sleeve in the described turning set.
Further again, the bottom of described turning set is connected with described slide body top by a fixed axis, one end of described fixed axis is connected to the bottom of described turning set, and the other end of described fixed axis is provided with a bearing, and described bearing is fixed on the top of described slide body by a bearing gland.
Further, side at described rotation hole is provided with moving block, be provided with the wear-resistant guiding piece in the described moving block, one end of described wear-resistant guiding piece is connected with Bidirectional-screw in the described rotation hole, the other end of described wear-resistant guiding piece is provided with spring, and described spring is fixed on the side of described slide body by a spring capping.
The row limit device of coiler for trimmings of the present utility model, compared with prior art, by the Bidirectional-screw rotation slide unit about doing, Bidirectional-screw is moved back and forth, the part material of phase mutual friction is high-abrasive material in the relative motion, reduced the frictional force in the running, increase the flexibility of mechanism, consumable accessory has been changed more convenient, reduced the processing cost of the consumable accessory of phase mutual friction; After the guide rod slip, reduced the bond area of pollutant, increased the resistant to pollution ability of mechanism, make mechanism's energy durable in use, realize the purpose of this utility model.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
Description of drawings

Fig. 2 is the structural representation of slide unit of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the row limit device of coiler for trimmings of the present utility model, it comprises a support 100 and a slide unit 200, the upper end of described support 100 is provided with a two-way screw mandrel 110, the lower end of described support 100 is provided with a guide rod 120, and described slide unit 200 moves back and forth about on the described guide rod 120 by described Bidirectional-screw 110.
As shown in Figure 2, described slide unit 200 comprises a slide body 210, be provided with one on the described slide body 210 and be used for the rotation hole 211 that is connected with described Bidirectional-screw 110, the bottom of described slide body 210 is provided with a guide holder 220, be provided with the guide pin bushing 221 that is connected with described guide rod 120 in the described guide holder 220, guide pin bushing 221 is wear-resisting tin bronze material, and contamination resistance can be realized self-lubricating by force, reduces the maintenance in the use procedure.
The top of described slide body 210 is provided with a turning set 230, is provided with a wear-resistant sleeve 240 in the described turning set 230; Wear-resistant sleeve 240 is 45 steel quenching materials, is fixed by screw, is convenient for changing after the wearing and tearing.
The bottom of described turning set 230 is connected with described slide body 210 tops by a fixed axis 231, one end of described fixed axis 231 is connected to the bottom of described turning set 230, the other end of described fixed axis 231 is provided with a bearing 250, and described bearing 250 is fixed on the top of described slide body 210 by a bearing gland 251; Turning set 230 has reduced frictional force, for exempting from lubricating structure by free to rotate under the cooperation of bearing 250.
Be provided with moving block 260 in the side of described rotation hole 211, be provided with wear-resistant guiding piece 270 in the described moving block 260, one end of described wear-resistant guiding piece 270 is connected with Bidirectional-screw 110 in the described rotation hole 211, the other end of described wear-resistant guiding piece 270 is provided with spring 280, and described spring 280 is fixed on the side of described slide body 210 by a spring capping 281; Wear-resistant guiding piece 270 is promoted by spring 280, but auto-compensation after the wearing and tearing reduces the maintenance maintenance time.
In the course of work, pass waste edge wire in the turning set 230, slide unit 200 drives turning set 230 and the limit silk is done left and right sides iterative motion, and turning set 230 angle in motion process can be regulated the power of reducing friction automatically; Guide pin bushing 221 and the guide rod 120 of guide holder 220 are slidingly matched, and have reduced frictional force thereby reduced contact area.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
