Description

Technical Field

[0001] The present invention relates to the field of production of iron straps, and particularly to an iron strap slitting machine for pipeline production. Background Art

[0002] In pipeline production, iron straps are required to fix and protect pipelines. However, in the process of using a slitting machine to slit a sheet material to form iron straps, in order to avoid burrs on the cutting edges of the iron straps from scratching workers, additional grinding equipment is needed to process the burrs on the cutting edges of the iron straps, resulting in high costs. Furthermore, existing slitting machines usually apply a shearing force to the sheet material by two adjacent upper and lower slitting knives for slitting operations. However, after the sheet material is subjected to the shearing force of the two adjacent upper and lower slitting knives, as Figure 5 、 Figure 13 shown, the two cutting edges of the obtained straps will contract towards the middle, resulting in the overall arc shape of the strap, which affects the stable conveying and stable winding of the strap after slitting. Summary of the Invention

[0003] In order to overcome the disadvantages that in the process of using an existing slitting machine to slit a sheet material to form iron straps, additional grinding equipment is needed to process the burrs on the cutting edges of the iron straps, resulting in high costs, and during the slitting process, the two cutting edges of the obtained straps will contract towards the middle, resulting in the overall arc shape of the strap, which affects the stable conveying and stable winding of the strap after slitting, the present invention provides an iron strap slitting machine for pipeline production.

[0004] The technical implementation solution of the present invention is as follows: An iron strap slitting machine for pipeline production includes a slitting machine; two first connecting rollers arranged symmetrically up and down are rotatably connected to the slitting machine, and a plurality of slitting knives are arranged on each first connecting roller; a second connecting roller, a limiter, and a pressing ring are further included; two second connecting rollers arranged symmetrically up and down are rotatably connected to the slitting machine, and the second connecting rollers are located on the right side of the first connecting rollers; a plurality of limiters are arranged on each second connecting roller, and each limiter is provided with a first fixing portion and a second fixing portion for fixing the strap; the first fixing portion of each upper limiter is in contact with the second fixing portion of the corresponding lower limiter, and the first fixing portion of each lower limiter is in contact with the second fixing portion of the corresponding upper limiter; each limiter is provided with a grinding portion for grinding the burrs on the edge of the iron strap; a plurality of pressing rings for flattening the strap are fixedly connected to each second connecting roller, and the pressing rings are located between two adjacent first fixing portions.

[0005] More preferably, the width of the second fixing portion is greater than the width of the first fixing portion.

[0006] More preferably, it further includes an extrusion plate; a plurality of extrusion plates distributed in an annular array are slidably connected to each extrusion ring, and a spring is arranged between the extrusion plate and the extrusion ring.

[0007] More preferably, a first round roller is rotatably connected to one end of each extrusion plate away from the extrusion ring.

[0008] More preferably, all the slitting knives are slidably connected to the first connecting roller; all the limiters are slidably connected to the second connecting roller, all the extrusion rings are slidably connected to the second connecting roller, and locking bolts are arranged on all the slitting knives, all the limiters and all the extrusion rings.

[0009] More preferably, it further includes a connecting seat, an oil pipeline, a connecting frame, a coating plate, an elastic member and a connecting plate; at least two connecting seats are fixedly connected to the slitter; an oil pipeline is fixedly connected by the two connecting seats together; a connecting frame is slidably connected by the two connecting seats together; an elastic member is fixedly connected between all the connecting seats and the connecting frame; a plurality of coating plates for applying antirust oil to the cutting edge of the tape are arranged on the connecting frame, the coating plate is Z-shaped, and a sponge layer is arranged on the surface of the coating plate; all the coating plates are communicated with the oil pipeline; a connecting plate is arranged on one side of the connecting frame facing the limiter, and the connecting plate is located on the rotation path of the lower extrusion plate.

[0010] More preferably, the coating plate is slidably connected to the connecting frame through an electric slider; a chute for the electric slider to slide is arranged on the connecting frame.

[0011] More preferably, the oil pipeline is connected to all the coating plates through a hose.

[0012] More preferably, a second round roller is rotatably connected to one side of the connecting plate facing the limiter.

[0013] More preferably, the elastic force of the spring between the extrusion plate and the extrusion ring is greater than the elastic force of the elastic member.

[0014] The beneficial effects of the present invention are as follows: The present invention polishes the cutting edge of the tape through the polishing part, avoiding burrs remaining on the cutting edge of the tape, which may scratch workers during manual traction and subsequent use, and there is no need to use additional equipment to remove burrs before the tape is conveyed to an external winder, reducing costs.

[0015] The tape is flattened by the extrusion ring, solving the problem that when the sheet is slit by the slitting knife, the sheet is subjected to the shearing force of the upper and lower adjacent slitting knives, resulting in the front and rear cutting edges of the tape contracting towards the middle, causing the cutting edge of the tape to be far from the limiter, affecting the stable conveying and stable winding of the tape, and affecting the polishing of the cutting edge of the tape by the polishing part.

[0016] The flattening operation of the binding tape is performed by using the extrusion plate to replace the outer ring surface of the extrusion ring, avoiding the failure of flattening the binding tape due to the limited movement space of the binding tape after being fixed by the restrictor.

[0017] By setting the width of the second fixing part to be greater than that of the first fixing part, when the extrusion plate replaces the outer ring surface of the extrusion ring to perform the flattening operation on the binding tape, the second fixing part is used to ensure the support of the cutting edge of the binding tape, avoiding the cutting edge of the binding tape from detaching from the second fixing part to ensure the flattening effect of the extrusion plate on the binding tape.

[0018] The present invention also has the following beneficial effects: The first round roller is used to contact the binding tape instead of the extrusion plate, and during the flattening process, the first round roller rotates self - sufficiently, avoiding abrasion on the surface of the binding tape and affecting subsequent use.

[0019] When slitting the sheet material, the locking bolts on the slitting knife, restrictor and extrusion ring can be loosened, and then according to the width requirement of the binding tape, the slitting knife, restrictor and extrusion ring are pushed, and the locking bolts are tightened again to achieve the controllability of the slitting width of the binding tape.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1 As Figures 1-8 and Figure 13 shown, an iron strap slitter for pipeline production includes a slitter 1; two first connecting rollers 1001 arranged symmetrically up and down are rotatably connected to the slitter 1, and a plurality of slitting knives 1002 are arranged on each first connecting roller 1001; It further includes a second connecting roller 101, a restrictor 102 and an extrusion ring 103; two second connecting rollers 101 which are symmetrically arranged up and down are rotatably connected to the slitter 1, and the second connecting rollers 101 are located on the right side of the first connecting roller 1001; a plurality of restrictors 102 are arranged on each second connecting roller 101, and each restrictor 102 is provided with a first fixing portion 10201 and a second fixing portion 10203; the first fixing portion 10201 of each upper restrictor 102 is in contact with the second fixing portion 10203 of the corresponding lower restrictor 102, and the first fixing portion 10201 of each lower restrictor 102 is in contact with the second fixing portion 10203 of the corresponding upper restrictor 102; a grinding portion 10202 is arranged on each restrictor 102; a plurality of extrusion rings 103 are fixedly connected to each second connecting roller 101, and the extrusion rings 103 are located between two adjacent first fixing portions 10201.

[0024] Four servo motors 1003 are fixedly connected to the slitter 1, and the output ends of the two servo motors 1003 on the left are fixedly connected to the adjacent first connecting roller 1001, and the output ends of the two servo motors 1003 on the right are fixedly connected to the adjacent second connecting roller 101.

[0025] The width of the second fixing portion 10203 is greater than the width of the first fixing portion 10201.

[0026] It further includes an extrusion plate 104; a plurality of extrusion plates 104 distributed in an annular array are slidably connected to each extrusion ring 103, and a spring is arranged between the extrusion plate 104 and the extrusion ring 103.

[0027] One end of each extrusion plate 104 away from the extrusion ring 103 is rotatably connected to a first round roller 10401.

[0028] All the slitting knives 1002 are slidably connected to the first connecting roller 1001; all the restrictors 102 are slidably connected to the second connecting roller 101, all the extrusion rings 103 are slidably connected to the second connecting roller 101, and locking bolts are arranged on all the slitting knives 1002, all the restrictors 102 and all the extrusion rings 103, and the locking bolts are used to fix the slitting knives 1002 and the restrictors 102 on the corresponding first connecting roller 1001 and second connecting roller 101.

[0029] The working principle of the above embodiment is as follows: First, taking Figure 1 as the perspective reference, the side where the label of the slitter 1 is located is the left; When in use, as Figure 5As shown, the sheet is pushed between all the slitting knives 1002 by the staff or an external traction device. Then, the servo motor 1003 drives all the slitting knives 1002 through the first connecting roller 1001 to slit the sheet. After the sheet is slit, a number of strap tapes 111 are formed. Then, the staff or an external traction device pushes the slit strap tapes 111 between all the limiters 102. At this time, the servo motor 1003 drives all the limiters 102 through the second connecting roller 101 to convey the strap tapes 111 to the right; As Figure 6 shown, the cutting edges of the strap tapes 111 are fixed by the upper and lower adjacent limiters 102. After the strap tapes 111 are just conveyed out of the limiters 102, the strap tapes 111 are first pushed to an external winding device by the staff or an external traction device for winding.

[0030] It should be noted that, as Figure 6 shown, the first fixing part 10201 of each upper limiter 102 contacts the second fixing part 10203 of the corresponding lower limiter 102, and the first fixing part 10201 of each lower limiter 102 contacts the second fixing part 10203 of the corresponding upper limiter 102, so that the strap tapes 111 are discharged in a vertically staggered distribution after being limited by the corresponding limiters 102, which is convenient for the staff or an external traction device to perform traction operations on the strap tapes 111.

[0031] Furthermore, as Figure 7 shown, during the process of the limiter 102 conveying the strap tapes 111 to the right, the cutting edges of the strap tapes 111 are polished by the polishing part 10202 provided on the limiter 102, avoiding burrs remaining on the cutting edges of the strap tapes 111, which may scratch the staff during manual traction and subsequent use. Moreover, there is no need to use additional equipment to remove burrs before the strap tapes 111 are conveyed to the external winding device, reducing costs.

[0032] Furthermore, when the servo motor 1003 drives all the limiters 102 through the second connecting roller 101 to convey the strap tapes 111 to the right, the second connecting roller 101 also drives all the pressing rings 103 to rotate. Referring to Figure 4 , the outer ring surface of the pressing ring 103 contacts the middle part of the strap tapes 111. Thus, as the sheet is slit and the strap tapes 111 enter between the limiters 102, the outer ring surface of the pressing ring 103 presses the middle part of the strap tapes 111 to flatten the strap tapes 111, solving the problem that when the sheet is slit by the slitting knives 1002, the sheet is subjected to the shearing force of the upper and lower adjacent slitting knives 1002, causing the front and rear cutting edges of the strap tapes 111 to contract towards the middle, and the overall shape of the strap tapes 111 is Figure 13 shown as an arc shape, resulting in the cutting edges of the strap tapes 111 being far away from the limiters 102, affecting the stable conveyance and stable winding of the strap tapes 111, and affecting the polishing of the cutting edges of the strap tapes 111 by the polishing part 10202.

[0033] Furthermore, by arranging a plurality of extrusion plates 104 on the extrusion ring 103, during the rotation of the extrusion ring 103, the extrusion plates 104 replace the outer ring surface of the extrusion ring 103 to flatten the wrapping belt 111. Since the extrusion plates 104 protrude from the outer ring surface of the extrusion ring 103, that is, before the wrapping belt 111 enters between all the limiters 102, the extrusion plates 104 first flatten the wrapping belt 111, thereby preventing the wrapping belt 111 from being restricted in its movable space after being fixed by the limiters 102. The limit causes the packing tape 111 to fail to be flattened, which affects the conveying of the packing tape 111 and the grinding of the cutting edge. It should be noted that when the extrusion plate 104 rotates and contacts the packing tape 111, while the extrusion plate 104 applies pressure to the packing tape 111, the packing tape 111 also applies a reaction force to the extrusion plate 104, causing the extrusion plate 104 to move toward the inside of the extrusion ring 103, and the spring between the extrusion plate 104 and the extrusion ring 103 is compressed until the extrusion plate 104 is completely retracted into the extrusion ring 103.

[0034] Further, by setting the width of the second fixing portion 10203 to be greater than the width of the first fixing portion 10201, as Figure 6 As shown, when the extrusion plate 104 replaces the outer ring surface of the extrusion ring 103 to flatten the strap 111, the second fixing portion 10203 ensures that the cut edge of the strap 111 is supported to prevent the cut edge of the strap 111 from detaching from the second fixing portion 10203, thereby ensuring the flattening effect of the extrusion plate 104 on the strap 111.

[0035] On the basis of the above technical effects, the present invention also has the following advantages: like Figure 8 As shown, when the extrusion plate 104 replaces the extrusion ring 103 to flatten the outer ring surface of the wrapping tape 111, the first round roller 10401 provided on the extrusion plate 104 contacts the wrapping tape 111. After the first round roller 10401 contacts the wrapping tape 111, as the extrusion plate 104 rotates following the extrusion ring 103, relative friction is generated between the first round roller 10401 and the wrapping tape 111, and the first round roller 10401 rotates on itself to avoid causing wear on the surface of the wrapping tape 111 and affecting subsequent use.

[0036] like Figure 4 As shown, when the sheet is cut, the locking bolts on the slitting knife 1002, the limiter 102 and the extrusion ring 103 can be loosened manually in advance, and then the slitting knife 1002, the limiter 102 and the extrusion ring 103 can be pushed to the appropriate position according to the width requirement of the wrapping tape 111, and the locking bolts can be tightened again to achieve controllable cutting width of the wrapping tape 111.

[0037] Example 2 On the basis of Example 1, Figure 1 and Figures 9-12As shown in the figure, it further includes a connecting seat 201, an oil delivery pipe 202, a connecting frame 203, a coating plate 204, an elastic member 205 and a connecting plate 206; two connecting seats 201 are fixedly connected to the slitter 1; a single oil delivery pipe 202 is fixedly connected to the two connecting seats 201 together, and the oil delivery pipe 202 is connected to an external delivery pump, and the delivery pump is used to deliver the rust preventive oil into the oil delivery pipe 202; a connecting frame 203 is slidably connected to the two connecting seats 201 together; an elastic member 205, which is a spring, is fixedly connected between all the connecting seats 201 and the connecting frame 203; a plurality of coating plates 204 are arranged on the connecting frame 203, the coating plate 204 is arranged in a Z shape, and a sponge layer 20401 is arranged on the surface of the coating plate 204; all the coating plates 204 communicate with the oil delivery pipe 202; a connecting plate 206 is arranged on the side of the connecting frame 203 facing the limiter 102, and the connecting plate 206 is located on the rotation path of the lower pressing plate 104.

[0038] The coating plate 204 is slidably connected to the connecting frame 203 through an electric slider 20402; a chute for the electric slider 20402 to slide is arranged on the connecting frame 203.

[0039] The oil delivery pipe 202 is connected to all the coating plates 204 through hoses.

[0040] A second round roller 20601 is rotatably connected to the side of the connecting plate 206 facing the limiter 102.

[0041] The spring force between the pressing plate 104 and the pressing ring 103 is greater than the elastic force of the elastic member 205 to ensure that the pressing plate 104 stably pushes the connecting frame 203 downward.

[0042] The working principle of the above embodiment is as follows: When the tape 111 is conveyed to the right through the limiter 102 described in Embodiment 1: As Figure 9 shown, the cutting edge of the tape 111 will contact the coating plate 204, so as to apply the rust preventive oil to the cutting edge of the polished tape 111 through the coating plate 204, ensuring the rust prevention performance of the cutting edge of the tape 111, and avoiding that when the tape 111 is used to protect the pipeline subsequently, the cutting edge of the tape 111 is quickly corroded, resulting in the penetration of corrosive substances such as external water vapor through the tape 111 to corrode the pipeline; in addition, in the present invention, the cutting edge of the tape 111 is automatically coated with rust preventive oil during the slitting process, without the need to set up additional equipment for coating the cutting edge of the tape 111 with rust preventive oil, reducing costs; it should be noted that the rust preventive oil is replenished into the coating plate 204 through the oil delivery pipe 202, and the rust preventive oil in the coating plate 204 is discharged onto the sponge layer 20401 through the pores thereon; it should be noted that by flattening the tape 111 with the pressing plate 104, it is also possible to ensure that the cutting edge of the tape 111 contacts the coating plate 204, ensuring the coating of the rust preventive oil on the cutting edge of the tape 111.

[0043] Further, as Figure 11 shown, when the lower extrusion ring 103 drives the extrusion plate 104 thereon to rotate and flatten the wrapping tape 111, the extrusion plate 104 on the lower extrusion ring 103 will contact the connecting plate 206. As the extrusion plate 104 follows the extrusion ring 103 to rotate, the extrusion plate 104 exerts a downward thrust on the connecting plate 206, causing the connecting frame 203 to drive the coating plate 204 to move downward, and the elastic member 205 is compressed. After the extrusion plate 104 passes by the connecting plate 206, at this time, the connecting frame 203 resets upward under the action of the elastic member 205. In this way, during the process of the extrusion plate 104 flattening the wrapping tape 111, the connecting frame 203 drives the coating plate 204 to reciprocate up and down to apply anti-rust oil to the cutting edge of the wrapping tape 111, solving the problem that the cutting edge of the wrapping tape 111 always contacts the coating plate 204 at the same position, resulting in more serious wear of the sponge layer 20401 at the contact part and the need to frequently replace the sponge layer 20401. At the same time, it solves the problem that the contact position between the sponge layer 20401 and the cutting edge of the wrapping tape 111 is always squeezed by the wrapping tape 111, resulting in inconvenient flow of anti-rust oil and the inability to fully apply anti-rust oil to the cutting edge of the wrapping tape 111.

[0044] Further, by driving the coating plate 204 to reciprocate up and down through the connecting frame 203 to apply anti-rust oil to the cutting edge of the wrapping tape 111, it can also avoid the problem of waste of anti-rust oil at the remaining positions of the coating plate 204 due to insufficient use of the coating plate 204.

[0045] Based on the above technical effects, the present invention further has the following advantages: As Figure 10 shown, when manually adjusting the slitting knife 1002 and the restrictor 102 according to the width requirement of the wrapping tape 111, the operator can control the electric slider 20402 to drive the coating plate 204 to move horizontally along the connecting frame 203 to adjust the position of the coating plate 204 to adapt to the application of anti-rust oil to wrapping tapes 111 of different widths.

[0046] As Figure 10 shown, the oil delivery pipe 202 is connected to all the coating plates 204 through hoses, avoiding the oil delivery pipe 202 from blocking the movement of the coating plate 204.

[0047] As Figure 10 shown, when the lower extrusion plate 104 contacts the connecting plate 206 and pushes the connecting plate 206 to move upward, the first round roller 10401 on the extrusion plate 104 contacts the second round roller 20601 on the connecting plate 206, and the first round roller 10401 and the second round roller 20601 rotate by rubbing against each other, reducing the wear of the extrusion plate 104 and the connecting plate 206 and improving the service life.

[0048] It should be understood that this embodiment is only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
