Description

Technical Field

[0001] The present invention relates to the technical field of trimming shears, and in particular to a chute structure for trimming shears and the trimming shears. Background Art

[0002] The trimming shear is an important equipment of the cold rolling continuous trimming production line. When producing trimming materials, the waste edges after trimming will move to the shredder through the waste chute, and then the shredder will break the waste edges, and finally be transported to the waste hopper by the conveyor belt for recycling. At present, the waste chute is prone to blockage during the production process, and since the existing waste chute's dredging slot and the slot pressure cover are often connected by bolts, on the one hand, when the waste chute is blocked, the connecting bolts need to be frequently removed, which is not convenient for operators to dredge the waste chute. On the other hand, the bolt connection method is not convenient for operators to find the blockage at the first time. Sometimes, the blockage problem can only be found when a large amount of waste edges accumulate inside the waste chute, causing shearing abnormality. At this time, it is extremely inconvenient to dredge the waste channel, which leads to a large waste of labor costs and time costs. At the same time, the large amount of waste edges will also affect the normal operation of the trimming shear, affecting production efficiency and product quality. Utility Model Content

[0047] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0048] like Figure 1 and Figure 2 As shown, according to the first aspect of the embodiment of the present disclosure, a chute structure for a trimming shear is proposed, comprising: a bracket portion 100; a trough body portion 200, which is provided with a connected material transfer channel and a slot, the slot is opened along the extension direction of the material transfer channel, and the feed end of the material transfer channel is used to correspond to the waste discharge side arrangement of the trimming shear; a pressure cover portion 300, rotatably arranged on the bracket portion 100, for covering or opening the slot, and the pressure cover portion 300 has a covering position and an opening position along the rotation direction; wherein, when the pressure cover portion 300 is in the covering position, the pressure cover portion 300 covers the slot; when the pressure cover portion 300 is in the opening position, the pressure cover portion 300 opens the slot.

[0049] A chute structure for a trimming shear proposed in an embodiment of the present disclosure comprises: a bracket portion 100, a trough portion 200 and a pressure cover portion 300, wherein the trough portion 200 is used to receive and guide the waste edges generated by the trimming shear, the trough portion 200 is provided with a connected feed channel and a notch, the feed end of the feed channel is used to be arranged corresponding to the waste discharge side of the trimming shear, that is, the feed channel is located on the side where the trimming shear generates waste edges, and is arranged corresponding to the waste edge discharge area generated by the trimming shear, so that the feed channel can receive the waste edges generated by the trimming shear and guide the waste edges generated by the trimming shear to the edge shear for breaking, the notch is opened along the extension direction of the feed channel, when the feed channel is blocked, it is convenient to dredge the feed channel, the pressure cover portion 300 is rotatably arranged on the bracket portion 100, and rotates along the rotation direction, the pressure cover portion 300 By rotating at different angles, the cover portion 300 can have a covering position and an open position relative to the notch. When the cover portion 300 is in the covering position, the cover portion 300 can cover the notch of the trough body portion 200. By rotating the cover portion 300 at a certain angle, the notch of the trough body portion 200 can be completely opened. At this time, the cover portion 300 is in the open position. In practical applications, the rotation range of the cover portion 300 can be set between the covering position and the open position, that is, when the cover portion 300 is between the open position and the covering position, the cover portion 300 can open part of the notch. Such a setting can make it more convenient and flexible for the cover portion 300 to cover or open the notch, and the cover portion 300 can be rotated at different angles according to actual conditions, so that it is easier to operate the cover portion 300 to open part of the notch to clear the material passage.

[0050] It can be understood that in actual applications, the trough body 200 can be arranged on the bracket part 100, so that the trough body 200 and the pressure cover part 300 are relatively fixed, so that the pressure cover part 300 can cooperate with the slot; the trough body 200 can also be arranged on the frame of the trimming shear, so that the trough body 200 and the frame of the trimming shear are relatively fixed, so as to facilitate the feed end of the feed channel to receive the waste edges generated by the trimming shear; the trough body 200 can also be arranged on the bracket part 100 and the frame of the trimming shear at the same time, which is convenient for the feed end of the trough feed channel to receive the waste edges generated by the trimming shear, and for the pressure cover part 300 to cooperate with the slot.

[0051] It is understandable that the feed channel can be arranged at an angle so that the feed end of the feed channel is higher than the discharge end of the feed channel, so that the waste edges can move through the feed channel under the action of gravity to the scrap shear for shredding.

[0052] It should be noted that, under normal circumstances, the waste edges generated by the trimming shear will move to the edge crushing shear through the waste channel of the waste chute. However, since the working state of the trimming shear is usually maintained in a high-speed shearing state, the waste edges generated by the trimming shear will hit the inner wall of the waste channel, causing the waste edges to bend, and thus easily accumulate inside the waste channel and cannot enter the edge crushing shear normally. Among them, waste edges are very likely to accumulate in the slot. In the current traditional technology, the unblocking slot of the waste chute and the slot pressure cover are often connected by bolts. On the one hand, the connecting bolts need to be removed every time the waste chute is blocked, and due to the squeezing of the waste edges, it is not convenient to remove the connecting bolts, which makes it inconvenient for the operator to dredge the waste chute. On the other hand, the bolted connection method is not easy for the operator to find the blockage at the first time. Sometimes, the blockage problem will not be discovered until a large amount of waste edges accumulate in the waste chute, causing shearing abnormality. At this time, it is extremely inconvenient to clear the waste channel, which results in a large waste of labor costs and time costs. At the same time, the large amount of waste edges accumulated will also affect the normal operation of the trimming shears, affecting production efficiency and product quality. Compared with the conventional technology, the trimming shear chute structure proposed in the first aspect of the embodiment of the present disclosure is based on the aforementioned setting, which can make the covering and opening of the slot more convenient. When the waste edges block the material transfer channel, it is convenient for the operator to clear the material transfer channel through the slot. At the same time, if the waste edges accumulated in the slot will lift up the pressure cover part 300, the pressure cover part 300 will rotate and open part of the slot, so that the operator can find the blockage problem according to the situation of the pressure cover part 300, thereby avoiding the large amount of waste edges accumulated in the material transfer channel, affecting the normal operation of the trimming shears and causing the reduction of product quality. At the same time, it is also conducive to the rapid response and efficient processing of the waste edge blockage problem, which can save labor costs and time costs and improve production efficiency.

[0053] In some examples, such as Figure 1 and Figure 2 As shown, the cover part 300 includes: a spindle 310, which is arranged on the bracket part 100, and the spindle 310 is arranged along the width direction of the slot body part 200; a connecting rod 320, which is rotatably connected to the spindle 310, and the extension direction of the connecting rod 320 is different from the extension direction of the spindle 310; a cover body 330, which is connected to one end of the connecting rod 320 and is used to cover or open the slot; wherein, when the cover part 300 is in the covering position, the cover body 330 covers the slot; when the cover part 300 is in the opening position, the cover body 330 opens the slot.

[0054] In the above technical solution, the gland part 300 includes a spindle 310, a connecting rod 320 and a gland body 330, wherein the gland body 330 is used to cover or open the slot, the gland body 330 is connected to one end of the connecting rod 320, the connecting rod 320 is rotatably connected to the spindle 310, and the spindle 310 is arranged on the bracket. Such an arrangement allows the connecting rod 320 to rotate relative to the bracket with the spindle 310 as the axis, and at the same time, the connecting rod 320 will drive the gland body 330 to rotate together, the spindle 310 can be arranged along the width direction of the slot body 200, and the extension of the connecting rod 320 The extension direction is different from the extension direction of the core shaft 310, so that the rotation of the cover body 330 is a change of position along the extension direction of the chute, so that the cover body 330 covers or opens the slot, that is, when the cover part 300 is in the covering position, the cover body 330 covers the slot; when the cover part 300 is in the opening position, the cover body 330 opens the slot, and at the same time, the core shaft 310 is arranged along the width direction of the trough body 200, which can also constrain the range of movement of the cover part 300, which is beneficial to reduce the space occupied and is convenient for arranging the cover part 300 in actual applications.

[0055] It can be understood that the extension direction of the connecting rod 320 is different from the extension direction of the main shaft 310, so that during the rotation process, the pressure cover body 330 has a certain rotation radius relative to the rotation axis, that is, the pressure cover body 330 has a certain rotation radius relative to the main shaft, thereby ensuring that the pressure cover body 330 rotates a certain distance to cover or open the slot.

[0056] Exemplarily, the shape of the gland body 330 can be adapted to the groove shape setting, and the material of the gland body 330 can be 16Mn and tempered to make the hardness range HRC53 to HRC60 and the surface roughness Ra0.8, which can improve the wear resistance of the gland body 330 and make the surface smooth, which is conducive to the smooth movement of the waste edge in the waste chute.

[0057] In some examples, such as Figure 1 and Figure 2 As shown, the connecting rod 320 includes: a connecting block 321, which is provided with a connecting hole; a copper sleeve, which is inserted into the connecting hole, and the outer circumferential wall of the copper sleeve is interference fit with the connecting block 321, and the inner circumferential wall of the copper sleeve is clearance fit with the central shaft 310; a first connecting rod 322, one end of the first connecting rod 322 is connected to the connecting block 321, and the other end is connected to the pressure cover body 330, and the extension direction of the first connecting rod 322 is different from the extension direction of the central shaft 310.

[0058] In the above technical solution, the connecting rod 320 includes a connecting hole, a copper sleeve and a first connecting rod 322. The connecting block 321 is provided with a connecting hole, and the copper sleeve is inserted into the connecting hole. The outer circumferential wall of the copper sleeve and the connecting block 321 are interference fit to prevent the copper sleeve from moving relative to the connecting block 321. The copper sleeve is used to pass the spindle 310, and the inner circumferential wall of the copper sleeve and the spindle 310 are clearance fit to facilitate the copper sleeve to rotate relative to the spindle 310, that is, the connecting block 321 can rotate relative to the spindle 310. The first connecting rod 322 is used to connect the gland body 330 and the connecting block 321. One end of the first connecting rod 322 is connected to the connecting block 321, and the other end is connected to the gland body 330. The extension direction of the first connecting rod 322 is different from the extension direction of the spindle 310, which can extend the rotation radius of the gland body 330, so that the gland body 330 can rotate a certain angle to cover or open the slot.

[0059] It can be understood that a copper sleeve is provided between the connecting hole and the spindle 310 to protect the connecting block 321 and the spindle 310, and to avoid direct contact between the connecting block 321 and the spindle 310, which is beneficial to reducing the wear of the connecting block 321 and the spindle 310, and is beneficial to increasing the service life of the connecting block 321 and the spindle 310. At the same time, if the copper sleeve is worn, it is also convenient for maintenance and replacement.

[0060] For example, the interference fit tolerance between the outer circumferential wall of the copper sleeve and the connecting block 321 may adopt the tolerance grade H7 / p6, and the clearance fit tolerance between the inner circumferential wall of the copper sleeve and the spindle 310 may adopt the grade H7 / h6.

[0061] In some examples, such as Figure 1 and Figure 2 As shown, the connecting rod 320 further includes: a first stopper 323 disposed at one end of the spindle 310, the connecting block 321 is located between the first stopper 323 and the bracket portion 100, and the first stopper 323 covers one end of the connecting hole.

[0062] In the above technical solution, the connecting rod 320 also includes a first limit member 323, which is arranged at one end of the main shaft 310. The first limit member 323 is used to limit the connecting block 321. The connecting block 321 is located between the first limit member 323 and the bracket part 100. At the same time, the first limit member 323 also covers one end of the connecting hole. The first limit member 323 and the bracket part 100 are arranged in this way to limit the connecting block 321 from both ends of the main shaft 310 in the axial direction to prevent the connecting block 321 from axial movement on the main shaft 310.

[0063] In some examples, such as Figure 1 and Figure 2As shown, the connecting rod 320 also includes: a second limit member 324, which is arranged on the bracket part 100. When the pressure cover body 330 covers the slot, the second limit member 324 abuts against the first connecting rod 322, and the second limit member 324 is located between the feed end of the feed channel and the first connecting rod 322.

[0064] In the above technical solution, the connecting rod 320 also includes a second limit member 324, which is arranged on the bracket part 100. When the pressure cover body 330 covers the notch, the second limit member 324 is located between the feed end of the feed channel and the first connecting rod 322, and the second limit member 324 abuts against the first connecting rod 322. The second limit member 324 is used to limit the rotation of the first connecting rod 322, thereby limiting the rotation of the pressure cover body 330, so that the pressure cover body 330 can only rotate toward the discharge end of the feed channel in the covering position, and cannot rotate directly from the covering position to the feed end. When the feed channel is blocked, the pressure cover body 330 is rotated to open the notch. At this time, space can be left between the feed end and the notch of the feed channel, which is convenient for the operator to clear the accumulated waste edges to the discharge end of the feed channel.

[0065] For example, a top screw may be arranged on the first connecting rod 322 , and the top screw is used to abut against the second limiting member 324 , so that the covering position of the pressure cover portion 300 can be adjusted by adjusting the length of the top screw.

[0066] In some examples, such as Figure 1 and Figure 2 As shown, the gland portion 300 further includes: a weight assembly 340 disposed on the connecting rod 320 . When the gland body 330 covers the notch, the weight assembly 340 is used to apply torque to the connecting rod 320 to limit the first connecting rod 322 from being away from the second limiting member 324 .

[0067] In the above technical solution, the pressure cover part 300 also includes a counterweight assembly 340, which is arranged on the connecting rod 320. When the pressure cover body 330 covers the slot, the counterweight assembly 340 can be used to apply torque to the connecting rod 320. The counterweight assembly 340 can make the first link 322320 of the connecting rod 320 generate a torsional force close to the second limit member 324 to limit the first link 322 and prevent the first link 322 from moving away from the second limit member 324, thereby limiting the pressure cover body 330 and preventing the pressure cover body 330 from opening the slot.

[0068] It can be understood that the scrap edge will produce a certain impact force under the action of the trimming shears, thereby causing the scrap edge to move from the feed end of the material transfer channel to the discharge end of the material transfer channel. The scrap edge will impact the pressure cover body 330 during the movement. The impact force of the scrap edge impacting the pressure cover body 330 will cause the pressure cover body 330 to rotate from the covering slot to the open slot, and the torque of the counterweight assembly 340 can offset the impact force generated by the scrap edge impacting the pressure cover, thereby preventing the pressure cover body 330 from being frequently lifted under the impact of the scrap edge.

[0069] In some examples, such as Figure 1 and Figure 2 As shown, the counterweight assembly 340 includes: a support rod 341, which is arranged on the connecting rod 320, the support rod 341 extends along the radial direction of the central shaft 310, and the support rod 341 is formed with an external thread; a counterweight block 342, which is provided with an internal thread, and the counterweight block 342 is threadedly engaged with the support rod 341, so that the position of the counterweight along the radial direction of the central shaft 310 can be adjusted.

[0070] In the above technical solution, the counterweight assembly 340 includes a support rod 341 and a counterweight block 342. The support rod 341 is arranged on the connecting rod 320. The support rod 341 is formed with an external thread, and the counterweight block 342 is formed with an internal thread. The counterweight block 342 and the support rod 341 are threadedly matched, so that the counterweight block 342 can be adjusted on the support rod 341. When the counterweight block 342 is on the support rod 341, the counterweight block 342 will apply gravity to the support rod 341, so that the support rod 320 is smooth. 41 generates a torque for rotating relative to the main shaft 310, that is, the counterweight block 342 can make the connecting rod 320 generate an applied torque for rotating relative to the main shaft 310. Adjusting the position of the counterweight block 342 on the support rod 341 can change the size of the force arm generated by the counterweight block 342, thereby changing the size of the torque for rotating the connecting rod 320 relative to the main shaft 310. The support rod 341 extends in the radial direction of the main shaft 310, and the size of the generated torque can be easily changed by adjusting the position of the counterweight block 342.

[0071] Exemplarily, the support rod 341 may include two parts: an optical axis and a threaded shaft. The optical axis is used to connect the connecting rod 320, and the threaded shaft is used to cooperate with the counterweight block 342. The optical axis and the connecting rod 320 are connected by screws and positioning parts, so that the optical axis cannot move relative to the connecting rod 320.

[0072] In some examples, the gland body 330 is formed with a material receiving end. When the gland body 330 covers the slot, the material receiving end is arranged toward the feed end of the material passage, and the material receiving end is formed with a rounded corner structure.

[0073] In the above technical solution, the cover body 330 is formed with a material-meeting end, which is used to meet the impact of the waste edge. When the cover body 330 covers the notch, the material-meeting end is arranged toward the feed end of the material-transfer channel, and the material-meeting end is formed with a rounded corner structure. When the waste edge impacts the cover body 330, the rounded corner structure can make the waste edge continue to move toward the discharge end of the material-transfer channel under the guidance of the rounded corner, so as to avoid the waste edge being stuck at the material-meeting end of the cover body.

[0074] In some examples, such as Figure 1 and Figure 2 As shown, it also includes: a detection unit 350, which is arranged on the bracket and is used to detect the position information of the pressing cover unit 300; a control unit, whose signal is connected to the detection unit 350; and an alarm unit, whose signal is connected to the control unit; wherein the control unit is configured to control the alarm unit to generate alarm information according to the position information.

[0075] In the above technical solution, the chute structure for the trimming shear also includes a detection unit 350, a control unit and an alarm unit, wherein the detection unit 350 is arranged on the bracket, the control unit is connected to the detection unit 350 by signal, and the alarm unit is connected to the control unit by signal. The detection unit 350 is used to detect the position information of the capping unit 300 and transmit the position information to the control unit. When the position information of the capping unit 300 is different from the position where the capping unit 300 covers the slot, the control unit will control the alarm unit to generate an alarm message to remind the operator that the position of the capping unit 300 has changed and it is necessary to check whether the waste edges in the material transfer channel are accumulated and blocked.

[0076] It is understandable that the control unit can also be used to connect the signal to the trimming shears. When the position information of the capping part 300 is different from the position where the capping part 300 covers the notch, the trimming shears can be controlled to slow down or stop.

[0077] According to a second aspect of an embodiment of the present disclosure, a side trimmer is provided, comprising: a side trimmer chute structure as provided in any one of the first aspects above.

[0078] Since the trimming shears provided in the embodiment of the present disclosure include the trimming shears chute structure as proposed in any one of the first aspects above, they have all the beneficial effects of the trimming shears chute structure, which will not be elaborated here.
