CN203200402U - Shredding device - Google Patents

Abstract

The utility model discloses a shredding device which comprises a base plate, a cutter, a bi-directional air cylinder and an electro-magnetic valve. A cutting opening is machined in the base plate, the cutter is placed on the base plate, the cutter is connected with the bi-directional air cylinder, and the electro-magnetic valve controls the bi-directional air cylinder to move, so that the cutter is driven to move on the cutting opening in a bi-directional mode to complete shredding and returning actions. Through the structure, shredding success rate of shreds is improved, the cutter does not need to be replaced, a thread suction nozzle is eliminated and gas cost is lowered.

Description

Chasing-attachment

Technical field

The utility model relates to the technical field of weaving, relates in particular to a kind of chasing-attachment.

Background technology

Chasing-attachment is an indispensable part in the spinning line.In the prior art; as shown in Figure 1; generally F2 installation spinnerets 101 sprays silk between spinning; and chasing-attachment is placed on F1 godet roller 102 and up-coiler 103 tops between coiling; namely be installed in A place, site; its basic principle is: when fracture of wire occurs; by corresponding fracture of wire inductor on the up-coiler 103; the induction local flaw signal after computer is processed, is delivered to the chasing-attachment electromagnetic valve; by special use collection silk device that all strands are integrated a branch of; deliver on the chasing-attachment, as shown in Figure 2, be the schematic diagram of chasing-attachment in the prior art; cutting knife 201 is alloy blade; return and to fix on the V-seat 202, be provided with aspirator and chew 203 above V-seat 202, the tightening force that relies on collection silk device and the inertia of the first roller rotate the pulling force of generation; cutting knife 201 cuts off strand; the strand of edge of a knife top is chewed 203 by special-purpose aspirator and is siphoned away, and prevents that strand from continuing to be wrapped on godet roller 102 and the up-coiler 103, reaches the purpose of protection equipment.But this device has open defect in design: (1) shearing force is provided by the tightening force of collection silk device and the inertia force of the first roller, and shearing force is obviously not enough in actual use, causes to can't cut silk; (2) after POLYAMIDE YARNS oiled, flatness was high, and toughness is strong, and strand easily slides at the edge of a knife, caused strand and cut constantly; (3) cutting knife 201 easy abrasions cause cutting continuous situation aggravation, and per season must be changed a cutting knife 201.

In view of this, the inventor studies and improves chasing-attachment, and this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of chasing-attachment that need not to change cutting knife, and improves the chopping success rate of strand.

For achieving the above object, technical solution of the present utility model is:

A kind of chasing-attachment comprises substrate, cutting knife, two-way cylinder and electromagnetic valve, is processed with otch on the substrate, cutting knife places on the substrate, be connected with two-way cylinder on the cutting knife, the motion of the two-way gas control of solenoid control, and then drive the bidirectional-movement of cutting knife on otch to finish chopping and playback action.

Further, be processed with two otch on the described substrate.

Further, described cutting knife is made by stainless steel material.

After adopting said structure, cutting knife of the present utility model is by two-way air cylinder driven, and when fracture of wire occured, local flaw signal was after computer is processed, deliver to electromagnetic valve, two-way cylinder action, cutting knife transverse shifting, cut off strand at otch, the corresponding rhizoid of each otch, thereby reduced requirement to shearing force; In addition, with this device and be installed in godet roller between coiling and the up-coiler isolation, be installed between spinning, strand can not be wrapped on godet roller and the up-coiler after cutting off, owing to having cancelled aspirator and chew, saves gas cost simultaneously.

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Description of drawings

Fig. 1 is prior art spinning process units schematic diagram;

Fig. 2 is the structural representation of prior art chasing-attachment;

Fig. 3 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 3, the utility model has disclosed a kind of chasing-attachment, comprise substrate 1, cutting knife 2, two-way cylinder 3 and electromagnetic valve 4, substrate 1 is rectangular slab, is processed with otch 11 in a side of rectangular slab, cutting knife 2 is made by stainless steel material, be F type structure, place on the substrate 1, an end of cutting knife 2 is connected with two-way cylinder 3, the motion of the two-way cylinder 3 of electromagnetic valve 4 controls, and then drive the bidirectional-movement of cutting knife 2 on otch 11 to finish chopping and playback action.

After adopting said structure, cutting knife 2 of the present utility model is driven by two-way cylinder 3, when fracture of wire occured, local flaw signal was delivered to electromagnetic valve 4 after computer is processed, two-way cylinder 3 actions, cutting knife 2 transverse shiftings cut off strand at otch 2, each otch 2 corresponding rhizoid, thereby requirement to shearing force, strand disengagement success ratio nearly 100% have been reduced; In addition, with this device and godet roller 102 and up-coiler 103 isolation, specifically, as shown in Figure 1, godet roller 102 and up-coiler 103 are installed on F1 between coiling, and this device is installed on the B point place of F2 between spinning, and strand can not be wound on godet roller 102 and the up-coiler 103 after cutting off, chew 203 owing to having cancelled aspirator simultaneously, save gas cost.

Below only be a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.

Claims (3)

1. chasing-attachment, it is characterized in that: comprise substrate, cutting knife, two-way cylinder and electromagnetic valve, be processed with otch on the substrate, cutting knife places on the substrate, be connected with two-way cylinder on the cutting knife, the motion of the two-way gas control of solenoid control, and then drive the bidirectional-movement of cutting knife on otch to finish chopping and playback action.
