Description

TECHNICAL FIELD

[0001] The utility model relates to a fiber production equipment field, specifically provides a new type of pulp iron wire shearing device. BACKGROUND

[0002] In the viscose fiber production process, the raw material pulp is generally stored, transported, etc. in the form of pulp bag. When the pulp is discharged, the pulp bag needs to be pretreated, that is, the iron wire and the packaging paper on the pulp bag are removed, and then the material is fed into the immersion barrel. The traditional iron wire removal method is that workers use diagonal pliers to manually cut the iron wire. However, due to the close adhesion of the iron wire and the pulp, it is difficult to operate with ordinary diagonal pliers, and the iron wire is prone to slipping, which is not conducive to quickly and efficiently completing the pretreatment process of the pulp bag. Although there are automatic pulp iron wire shearing devices at present, most ordinary automatic devices only simulate manual shearing methods, and the shearing tongs have low positioning efficiency, the iron wire still slips during shearing, and the automatic device configuration is complex and the equipment manufacturing cost is high, which is not conducive to production application. Therefore, an iron wire shearing device with low cost and convenient and efficient iron wire removal is proposed. SUMMARY

[0003] The utility model provides a new type of pulp iron wire shearing device to solve the problem of low efficiency of shearing the iron wire on the pulp bag.

[0004] The technical scheme of the utility model is as follows:

[0005] A new type of pulp iron wire shearing device, comprising a shearing frame, a power part and a shearing tongs part arranged on the shearing frame, the shearing tongs part comprising left and right tongs knives arranged symmetrically, the left and right tongs knives being provided with a wire hook at the bottom, the power part controlling the left and right tongs knives to close and open in opposite directions, and the wire hook being able to be inserted between the iron wire and the pulp when the left and right tongs knives close in opposite directions.

[0006] In this scheme, when the device is used to shear the pulp iron wire, the wire hook is inserted between the iron wire and the pulp during the closing process of the left and right tongs knives, the iron wire is slightly lifted, providing space for the shearing of the left and right tongs knives, and avoiding the slipping of the iron wire, which facilitates quick and efficient shearing.

[0007] Preferably, the left and right tongs knives are rotationally connected, the power link in the power part is rotationally connected with the right tongs knife or the left tongs knife, the power link is a telescopic rod, and the power link controls the closing and opening of the left and right tongs knives.

[0008] Preferably, the upper end of the left plier blade is rotationally connected with the shearing frame, and the lower end is provided with a beveled blade; the upper end of the right plier blade is connected with the power connecting rod, and the lower end is also provided with the beveled blade. In this scheme, the power connecting rod and the left and right plier blades form a crank slider mechanism, and by controlling the extension and retraction of the power connecting rod, the right plier blade is driven to move, so that the left and right plier blades are closed or moved away in opposite directions, and the structure is simple.

[0009] Preferably, the shearing plier part further comprises a connecting plate, the two ends of the connecting plate are respectively rotationally connected with the middle part of the left plier blade and the middle part of the right plier blade, and the beveled blades in the shearing plier part are in the same plane.

[0010] In this scheme, the left plier blade and the right plier blade are rotationally connected through the connecting plate, so that the rotation centers of the left plier blade and the right plier blade have a certain distance when they are closed, so that the angle between the beveled blades of the left plier blade and the right plier blade is as small as possible during the closing process, the outward sliding force of the iron wire during shearing is reduced, and the sliding of the iron wire is further avoided; at the same time, the beveled blades in the shearing plier part are in the same plane, so that the two beveled blades are extruded and sheared when shearing the iron wire, the force is dispersed on the cutting surface of the entire beveled blade, the iron wire can be better cut off, instead of concentrating force at the intersection of the two blades like a scissors, thereby avoiding the sliding of the iron wire.

[0011] Preferably, the extension and retraction directions of the power connecting rod are opposite to the length of the connecting plate, so as to ensure the stability of the posture of the shearing plier part when the power connecting rod is extended and retracted, so that the movement path of the left plier blade and the right plier blade is the same each time, which is beneficial to the positioning of the iron wire during shearing.

[0012] Preferably, the wire hook of the left plier blade and the wire hook of the right plier blade are respectively arranged on the two sides of the shearing plier part, so as to avoid the interference between the wire hooks of the left plier blade and the right plier blade when they are closed, and after the two wire hooks are inserted between the iron wire and the pulp, the iron wire at the shearing position is separated from the pulp and in a suspended state, which is convenient for the left plier blade and the right plier blade to cut off the iron wire. (Preferably, a holding handle is arranged on the shearing frame, which is convenient for workers to hold and use, and improves the shearing distance of the device.

[0013] Preferably, the power connecting rod is a hydraulic rod connected with a pressure pump, the working rod of the hydraulic rod is rotationally connected with the right plier blade, and the positioning rod of the hydraulic rod is fixed on the shearing frame. In this scheme, the opening and closing of the left plier blade and the right plier blade are controlled through the hydraulic rod, the labor intensity of workers is reduced, and the hydraulic rod can exert greater force on the left plier blade and the right plier blade compared with manpower, which is more conducive to the cutting of the iron wire.

[0014] Preferably, the beveled blade on the right plier blade is detachably connected with the right plier blade, and the beveled blade on the left plier blade is detachably connected with the left plier blade.

[0015] In the scheme, since the height of the wire lifting hook lifting the iron wire is certain, the position of the beveled blade contacting the iron wire is fixed, long-term use will cause the beveled blade to wear or be damaged, through the detachable setting of the beveled blade, only replacing the low-cost blade can continue to use the device, greatly reducing the maintenance cost of the equipment.

[0016] The present application has the following advantages:

[0017] When the device is used to cut the pulp iron wire, the wire lifting hook is first inserted between the iron wire and the pulp during the closing process of the left and right shears, and the iron wire is lifted, providing space for the cutting of the left and right shears, the two wire lifting hooks lift the iron wire from both sides, limiting the displacement of the iron wire, avoiding the slipping of the iron wire during the closing and cutting process of the left and right shears, so as to quickly and efficiently complete the cutting of the iron wire.

DETAILED DESCRIPTION

[0024] In combination with the drawings, the specific implementation mode of the embodiments of the present application is used to clearly and completely illustrate the technical scheme of the present application.

[0025] Embodiment one:

[0026] A novel pulp iron wire cutting device, such as Figure 1As shown, it comprises a shearing frame 1, a power unit 2 and a shearing jaw unit 3 arranged on the shearing frame 1, the shearing jaw unit 3 comprises a left jaw blade 31 and a right jaw blade 32 arranged symmetrically, the bottom of the left jaw blade 31 and the right jaw blade 32 is provided with a wire hook 33, the power unit 2 controls the closing and opening of the left jaw blade 31 and the right jaw blade 32, when the left jaw blade 31 and the right jaw blade 32 are closed, the wire hook 33 can be inserted between the iron wire 4 and the pulp 5, and then the iron wire 4 is lifted, providing space for the shearing of the left jaw blade 31 and the right jaw blade 32.

[0027] Further, the upper end of the left jaw blade 31 is rotationally connected with the shearing frame 1, and the lower end is provided with a beveled blade 34, the upper end of the right jaw blade 32 is connected with the power connecting rod 21, and the lower end is also provided with the beveled blade 34. The power connecting rod 21 and the left and right jaw blades 32 form a crank slider mechanism, by controlling the extension and retraction of the power connecting rod 21, the right jaw blade 32 is driven to move, so that the left and right jaw blades 32 can be closed or moved away from each other, the left jaw blade 31 and the right jaw blade 32 are rotationally connected, one jaw blade can rotate relative to the other jaw blade, the rotational connection mode can be that the left jaw blade 31 and the right jaw blade 32 rotate around the same rotation axis, like scissors, or rotate around their own rotation axes. Figure 1 and Figure 2 As shown, the shearing jaw unit further comprises a connecting plate 35, the two ends of the connecting plate 35 are respectively rotationally connected with the middle part of the left jaw blade 31 and the middle part of the right jaw blade 32, the left jaw blade 31 and the right jaw blade 32 are rotationally connected through the connecting plate 35, so that the rotation centers of the left jaw blade 31 and the right jaw blade 32 have a certain distance when they are closed, so that the angle between the beveled blades 34 of the left jaw blade 31 and the right jaw blade 32 is as small as possible during the closing process, reducing the outward sliding force of the iron wire 4 during shearing, and further avoiding the sliding of the iron wire 4.

[0028] Specifically, the beveled blades 34 in the shearing jaw unit are connected by the connecting plate 35 and are in the same plane, when the left jaw blade 31 and the right jaw blade 32 are in an open state, the adjacent surfaces of the upper half of the left jaw blade 31 and the right jaw blade 32 are parallel to each other, and the lower half forms an acute angle opening, when the power connecting rod 21 is retracted, the upper end of the right jaw blade 32 moves away from the upper end of the left jaw blade 31, at this time, the right jaw blade 32 in action makes the connecting plate 35 rotate the left jaw blade 31, the upper half of the left jaw blade 31 and the right jaw blade 32 forms an acute angle opening, and the lower half is closed, that is, the blades of the beveled blades 34 on the left jaw blade 31 and the right jaw blade 32 contact each other to perform shearing action. And the two beveled blades 34 are extruded and sheared when shearing the iron wire 4, the force is dispersed on the cutting surface of the entire beveled blade 34, which can better cut off the iron wire 4, rather than concentrating the force at the intersection of the two blades like scissors.

[0029] Further, the power link 21 in the power unit 2 is rotatably connected with the right jaw 32 or the left jaw 31, and the power link 21 is telescopic, providing power for the opening and closing of the shearing jaw unit, and the power link 21 can be driven by an automatic power element such as a hydraulic rod connected with the driving unit, reducing the labor intensity of workers, and being able to exert greater force on the left jaw 31 and the right jaw 32, while also being able to be manually driven by rotating the handle, and the specific manual driving scheme refers to the transmission mode of the existing manual clamping jaw, and it is preferred that the telescopic power link 21 is controlled by a hydraulic rod.

[0030] It should be noted that, as shown in Figure 3 the wire hook 33 includes a mounting plate 331 and a hook tip 332, the mounting plate 331 is mounted on the side of the left jaw 31 and the right jaw 32, so that the hook tip 332 protrudes along the bottom surface of the left jaw 31 and the right jaw 32 towards the opposite jaw, and the distance from the hook tip 332 of the wire hook 33 on the left jaw 31 to the rotation center of the left jaw 31 is greater than the distance from the lowermost end of the beveled blade 34 on the left jaw 31 to the rotation center of the left jaw 31, and the distance from the hook tip 332 of the wire hook 33 on the right jaw 32 to the rotation center of the right jaw 32 is greater than the distance from the lowermost end of the beveled blade 34 on the right jaw 32 to the rotation center of the right jaw 32, which can avoid the interference between the wire hook 33 when the left jaw 31 and the right jaw 32 are closed, while ensuring that the wire hook 33 can be inserted between the iron wire 4 and the pulp 5 before the left jaw 31 and the right jaw 32 are completely closed, that is, the wire hook 33 hooks the iron wire 4 before the beveled blade 34 contacts the iron wire 4, so that the iron wire 4 at the shearing position is separated from the pulp 5 and is in a suspended state, facilitating the left jaw 31 and the right jaw 32 to cut the iron wire 4.

[0031] Further, since the height at which the wire hook 33 lifts the iron wire 4 is constant, the position at which the beveled blade 34 contacts the iron wire 4 is fixed, and long-term use can cause the beveled blade 34 to wear or be damaged, so the beveled blade 34 on the right jaw 32 is detachably connected with the right jaw 32, and the beveled blade 34 on the left jaw 31 is detachably connected with the left jaw 31, and through the detachable setting of the beveled blade 34, only the low-cost blade needs to be replaced to continue using the device, greatly reducing the maintenance cost of the equipment.

[0032] Embodiment Two:
