Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only one sub-embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic view illustrating a top view structure of an unwinding apparatus according to an embodiment of the present invention, the unwinding apparatus 100 includes: the device comprises a mounting plate 10, a tensioning shaft 20, a sliding plate 12, a screw rod assembly 30 and a first guide assembly 40.

Referring also to fig. 3, the mounting plate 10 may be a fixed plate. The tension shaft 20 is rotatably connected to the mounting plate 10 and can axially move relative to the mounting plate 10. It is understood that the tensioning shaft 20 can rotate relative to the mounting plate 10, and the tensioning shaft 20 can also move relative to the mounting plate 10 along the axial direction of the tensioning shaft 20. The tensioning shaft 20 is used for placing the material roll 11, and the material roll 11 is placed at one end of the tensioning shaft 20, so that the material roll 11 can be unreeled through the tensioning shaft 20. It should be understood that the tensioning shaft 20 is a whole body having the function of tensioning and loosening the material roll 11, and is not a single shaft or an end part.

The sliding plates 12 are arranged in parallel at intervals on one side of the mounting plate 10, and the area of the sliding plates 12 may be smaller than that of the mounting plate 10. The sliding plate 12 is connected with one end of the tension shaft 20 by fixed sleeving, welding or using a fastener, so long as the sliding plate 12 is fixed with one end of the tension shaft 20.

The screw rod assembly 30 is disposed on the mounting plate 10 and connected to the sliding plate 12, it can be understood that one end of the screw rod assembly 30 can be fixedly connected to the mounting plate 10, and the other end penetrates through the sliding plate 12. The screw rod assembly 30 is used for driving the sliding plate 12 and the tensioning shaft 20 to axially move relative to the mounting plate 10, and the screw rod assembly 30 can convert the rotary motion into a linear motion, so that when the screw rod assembly 30 is driven to rotate by other power driving parts (e.g., a motor, etc.), the sliding plate 12 penetrating through the screw rod assembly 30 relatively makes a linear motion.

The first guide assembly 40 is disposed on the mounting plate 10 and connected to the sliding plate 12, one end of the first guide assembly 40 is fixed on the mounting plate 10, and the other end penetrates through the sliding plate 12.

It can be understood that when the screw assembly 30 drives the sliding plate 12 to move, since the first guide assembly 40 is disposed on the sliding plate 12 and parallel to the screw assembly 30, the sliding plate 12 and the tensioning shaft 20 move linearly along the first guide assembly 40, and the first guide assembly 40 can perform a good guiding function.

In some application scenarios, only a single rod or shaft is generally used in the unwinding mechanism, and the single rod or shaft not only needs to bear the pressure, gravity and the like of related components, but also needs to transmit driving force, so that under a long-time high-intensity working environment, the structure of the single rod or shaft is easily damaged or even completely destroyed, and in a severe case, other components are even affected. By arranging the first guide assembly 40, part of the force on the screw rod assembly 30 can be transferred to the first guide assembly 40 through the sliding plate 12, and the first guide assembly 40 not only plays a role in stable guiding, but also plays a role in sharing the force as a firm rigid support.

The lead screw fixing base 301 may be fixedly attached to the mounting plate 10, for example, by a fastener or the like. The screw 302 is rotatably connected with the screw fixing seat 301, that is, the screw 302 can rotate along the axial direction of itself relative to the screw fixing seat 301 under the action of an external driving force. The lead screw 302 may be a T-lead screw, a ball screw, or the like. The feed screw nut 303 is sleeved on the feed screw 302 and connected with the sliding plate 12, that is, the center of the feed screw nut 303 is sleeved on the feed screw 302, and the outer edge can be connected with the sliding plate 12 through a fastener. The lead screw 302 is parallel to the first guide bar 401.

The unwinding apparatus 100 may further include a connection block 320, and the connection block 320 connects the lead screw 302 and the first guide rod 401. It is understood that the lead screw 302 can be sleeved with a first bearing (not shown), and the first bearing is fixed in the connecting block 320. The connection of the connection block 320 may be a detachable fixed connection, so that it may be conveniently installed or detached.

Through the mode, the rotation of the screw rod 302 can be more stable, and the probability of deviation in the rotation process of the screw rod 302 can be further reduced.

The connection between the second guide bar 421 and the second guide sleeve 422 is the same as the connection between the first guide bar 401 and the first guide sleeve 402, and reference may be made to the description of the above embodiments. And will not be described in detail herein.

The third guide assembly 44 may further include a third guide rod 441 and a third guide sleeve 442, the third guide sleeve 442 being disposed on the mounting plate 10. It is understood that the third guide sleeve 442 may be fixed to the mounting plate 10 through the side facing the connecting plate 14. The third guide sleeve 442 is slidably connected with a third guide rod 441, one end of the third guide rod 441 is connected with the connecting plate 14, and the other end of the third guide rod is inserted into the mounting plate 10 and connected with the second roller 52. The connection between the third guide rod 441 and the third guide sleeve 442 is the same as the connection between the first guide rod 401 and the first guide sleeve 402, and reference may be made to the description of the above embodiments. And will not be described in detail herein.

Wherein the first guide bar 401, the second guide bar 421 and the third guide bar 441 are parallel to each other. The first and

second rollers

50, 52 are adapted to receive the web of material paid out from the roll 11 so that the web of material is output in a first direction. The first direction may be upward as shown in fig. 3, but may be other directions that may keep the tape straight. It is understood that the tension shaft 20, the end of the material roll 11, the first roller 50 and the second roller 52 are all located on the side of the mounting plate 10 away from the sliding plate 12. And the tensioning shaft 20, the first roller 50 and the second roller 52 are parallel to each other.

Through the above manner, when the sliding plate 12 moves along the axial direction of the first guide rod 401 relative to the mounting plate 10, the sliding plate 12 drives the first roller 50 and the second roller 52 to move synchronously, so that the first roller 50, the second roller 52 and the tensioning shaft 20 are kept relatively still all the time in the deviation rectifying process, thereby facilitating synchronous discharging of the material roll 11.

In some embodiments, referring to fig. 1 and 3, the unwinding apparatus 100 may further include a first driving assembly 70. The first driving assembly 70 is disposed on the first guide bar 401. The first driving assembly 70 may further include a first fixing base 701, a first driving member 702, and a first driving wheel 703.

The first fixing seat 701 is fixedly connected with one end of the first guide bar 401. The first driving member 702 is disposed on the first fixing seat 701, and the first driving member 702 may be a driving motor. The driving end of the first driver 702 is connected to a first driver 703. One end of the screw rod 302 can be further provided with a first driven wheel 704, and the first driving wheel 703 is connected with the first driven wheel 704 in a matching way. For example, the first driving wheel 703 and the first driven wheel 704 may be connected by a belt 705, or may be connected by gear engagement or the like. The first driving member 702 is used to drive the first driving wheel 703 to rotate the first driven wheel 704, so that the sliding plate 12 moves relative to the mounting plate 10 along the axial direction of the first guide rod 401.

Through the mode, the first guide rod 401 can be used as a main support to bear the first driving assembly 70, so that the influence of the gravity of the first driving assembly 70 on the screw rod assembly 30 is reduced, the bearing load of the screw rod assembly 30 can be reduced, and the probability of damage to the screw rod assembly 30 is reduced.

In some embodiments, with continued reference to fig. 1 and 3, a deviation sensor 60 may also be positioned between the first pass roller 50 and the second pass roller 52. The deviation sensor 60 is used to detect deviation of the tape outputted in the first direction. The deviation sensor 60 may be electrically connected to a control device (not shown), which may be a PLC (Programmable Logic Controller) or the like. That is, the deviation rectifying sensor 60 can feed back a corresponding electrical signal to the control device, and the control device controls the first driving member 702 to rectify the deviation.

It can be understood that the material roll 11 on the tension shaft 20 is deviated along the width direction of the material roll during unwinding (i.e. along the axial direction of the tension shaft 20 in fig. 1), so that the material roll is deviated along the axial direction of the first roller 50 and the second roller 52 during unwinding from the first roller 50 and the second roller 52. Therefore, the deviation rectifying sensors 60 are arranged on the first roller 50 and the second roller 52, so that whether the material roll 11 has a position deviation in the unreeling process can be accurately detected, if so, an electric signal can be fed back to the control device through the deviation rectifying sensors 60, and the control device controls the first driving member 70 to drive the sliding plate 12 to drive the tensioning shaft 20, the first roller 50 and the second roller 52 to move close to or away from the mounting plate 10, so that the deviation rectification is realized.

In some embodiments, referring to fig. 1, the unwinding apparatus 100 may further include a second driving assembly 72. The second drive assembly 72 is disposed on the slide plate 12. The second driving assembly 72 may further include a second fixing seat 721, a second driving member 722, and a second driving wheel 723.

The second fixed base 721 is connected to the sliding plate 12. The second driving member 722 is disposed on the second fixing seat 721, that is, the second driving member 722 is fixed on the second fixing seat 721. The second driving member 722 may be a driving motor or the like. The driving end of the second driving member 722 is connected with the second driving wheel 723. One end of the tensioning shaft 20 may further be provided with a second driven wheel 724, and the second driving wheel 723 is connected with the second driven wheel 724 in a matching manner, for example, may be connected through a belt 726 or connected through gear engagement or the like. The second driving member 722 can be used to drive the second driving wheel 723 to drive the second driven wheel 724 to rotate, so that the tensioning shaft 20 rotates relative to the mounting plate 10.

Alternatively, the second fixed base 721 may be connected to the sliding plate 12 through the connecting rod 725, so that an accommodating space may be provided between the second fixed base 721 and the sliding plate 12. The second driving pulley 723 and the second driven pulley 724 can be located in the accommodating space, so that the overall structure can be more compact.

In some embodiments, referring to fig. 4, 5 and 6, the tensioning shaft 20 may further include a tensioning sleeve 201 and a rotating shaft 203. The tensioning sleeve 201 is fixedly connected with the rotating shaft 203. One end of the rotating shaft 203 is fixedly connected with the tensioning sleeve 201, and the other end of the rotating shaft 203 is sleeved with a second driven wheel 724. It can be understood that the second driving member 722 drives the second driving wheel 723 to rotate the second driven wheel 724, and the second driven wheel 724 can further drive the rotating shaft 203 to rotate, so as to drive the tensioning sleeve 201 to rotate, thereby discharging the material roll 11.

Optionally, the surface of the tensioning sleeve 201 is provided with a guide wheel 22. The number of the guide wheels 22 may be multiple, and the guide wheels 22 may be uniformly distributed along the circumferential direction of the tensioning sleeve 201. It is understood that the guide wheel 22 may be an elongated shape extending along the axial direction of the tension sleeve 201, and the elongated guide wheel 22 may further include a plurality of small rollers side by side therein.

Referring to fig. 1 and 2 together, the unwinding apparatus 100 may further include a sensing sheet 62 and a sensor 64. The sensing sheet 62 may be a photoelectric sensing sheet or the like, and the sensor 64 may be a photoelectric sensor or the like. The sensing piece 62 is disposed on the second driven wheel 724. That is, the sensing piece 62 is fixed on the outer edge of the second driven wheel 724 and keeps rotating synchronously with the second driven wheel 724. The sensing piece 62 has a corresponding relationship with the guide wheel 22. It can be understood that the second driven wheel 724 is sleeved on the rotating shaft 203, and the sensing piece 62 is aligned with the guide wheel 22 (i.e. located on the same axis) relative to the axial direction of the rotating shaft 203, or the sensing piece 62 is not aligned with the guide wheel 22 relative to the axial direction of the rotating shaft 203, but has a certain angle difference relative to the cross section (the cross section is perpendicular to the axis of the rotating shaft 203).

Wherein the sensor 64 corresponds to the position of the sensing piece 62. The sensor 64 may be fixed on the sidewall of the connecting rod 725 through a fixing seat, for example, the sensor 64 may be U-shaped, so that the sensing piece 62 may rotate to the U-shaped position to realize detection, and of course, other detection methods may be used as long as the requirement for detecting the sensing piece 62 is met. The sensor 64 is used to detect the rotational position of the sensing piece 62 to determine whether the guide wheel 22 is rotated to a predetermined position. The predetermined position may be upward, i.e., the guide wheel 22 is oriented opposite to the direction of gravity of the roll 11.

It can be understood that in some application scenarios, when the material roll 11 is placed on the tension sleeve 201 (i.e. feeding), since the material roll 11 is heavy, the feeding process often needs to cooperate with each other in many ways, which is likely to cause low production efficiency. Because of the corresponding relationship between the sensing piece 62 and the guide wheel 22, the angle of rotation of the sensing piece 62 is always the same as the angle of rotation of the guide wheel 22.

Therefore, in the above manner, before feeding, the second driving element 722 drives the tensioning shaft to rotate, and when the sensor 64 detects the signal of the sensing sheet 62, it indicates that the guide wheel 22 on the tensioning sleeve 201 has reached the predetermined position (upward), so that during feeding, the material roll 11 abuts against the guide wheel 22, the material roll 11 can slide to the designated position on the guide wheel 22, and the feeding efficiency of the material roll 11 can be improved.

Optionally, referring to fig. 1, 4, 5 and 6, the tensioning shaft 20 may further include a sleeve 205. The sleeve 205 is sleeved on the rotating shaft 203, and for example, a plurality of second bearings 206, for example, 2 or 3, may be disposed on the rotating shaft 203. The second bearing 206 is fitted over the rotating shaft 203, and the sleeve 205 is fitted over the second bearing 206. So that rotation of the rotation shaft 203 relative to the sleeve 205 can be achieved.

Wherein, the mounting plate 10 may further be provided with a support base 16. At least one end of the supporting base 16 is provided with a roller base 162. For example, a roller seat 162 is provided at one end of the support base 16 facing the slide plate 12, at one end of the tension sleeve 201, or at both ends of the support base 162. The number of the roller bases 162 may be plural, for example, 3, 4, or 5. The roller base 162 is provided with a plurality of first rollers 164. The number of the first rollers 164 is the same as that of the roller holders 162. The sleeve 205 is inserted through the support base 16. The plurality of first rollers 164 are uniformly provided along the circumferential direction of the sleeve 205 and abut against the outer circumferential surface of the sleeve 205.

Through the above manner, the moving process of the sleeve 205 relative to the supporting seat 16 can be more stable, and the stability of the moving process of the tension shaft 20 relative to the mounting plate 10 can be further improved.

Optionally, referring to fig. 3, 4, 5, and 6, the tension shaft 20 may further include a guide sleeve 202, a driving shaft 204, a first spring 209, a pushing block 210, a tension block 211, a spring pressing block 212, a connecting end cover 213, a slip ring 214, and a sliding rod 215. The rotating shaft 203 is sleeved on the driving shaft 204 through the guide sleeve 202. The slip ring 214 is sleeved on the rotating shaft 203, and the slip ring 214 is connected with the rotating shaft 203 in a sliding manner.

The rotating shaft 203 may also be provided with a chute 216. The first spring 209 is disposed in the sleeve 205 and is fitted over the rotary shaft 203. The first spring 209 is located between the slip ring 214 and the second bearing 206 on the side close to the tension block 211. The driving shaft 204 is fixedly connected with the pushing block 210 through the connecting end cover 213, so that the pushing block 210 can be driven by the driving shaft 204 to move in the tensioning sleeve 201. It can be understood that, for example, when the driving shaft 204 moves to the right, the driving shaft 204 can drive the sliding rod 215 to move to the right, and further can drive the sliding ring 214 to compress the first spring 209, and the first spring 209 has a good buffering and damping effect. Therefore, the whole axial movement process can be more stable in the mode, and the probability of abrasion of parts is reduced.

The number of the tension blocks 211 can be 2, 3, 4 or 5, etc. The tensioning blocks 211 are uniformly distributed along the circumferential direction of the tensioning sleeve 201, and the tensioning blocks 211 can also slide along the sliding groove arranged on the tensioning sleeve 201 in the radial direction. One side of the tension block 211 abuts against the push block 210, the spring pressing block 212 is arranged on the tension sleeve 201, a second spring (not shown) is arranged between the spring pressing block 212 and the tension block 211, and the second spring abuts against the other side, far away from the push block 210, of the tension block 211. When the pushing block 210 moves rightwards, the second spring drives the tensioning block 211 to move radially inwards to enable the material roll 11 to be loosened; when the pushing block 210 moves to the left, the pushing block 210 drives the tension block 211 to move radially outward against the elastic force of the second spring so that the material roll 11 is fixed.

In some embodiments, referring to fig. 4, the unwinding apparatus 100 may further include a third driving assembly 74. A third drive assembly 74 is provided on the slide plate 12. The third driving assembly 74 may further include a third fixing seat 741, a third driving member 742, a latch 743, a second roller 744 and a connecting head 745. The third driver 742 may be a cylinder or the like. The third fixing seat 741 is connected to the second fixing seat 721. The third driving member 742 is disposed on the third fixing seat 741, and the third driving member 742 is fixed on the third fixing seat 741. The driving end of the third driving member 742 is connected to the latching 743, the second rollers 744 are located at two opposite ends of the latching 743, the second rollers 744 are connected to the connecting head 745, and the connecting head 745 is connected to the driving shaft 204 of the tensioning shaft 20.

It can be understood that the third driving member 742 can drive the driving shaft 204 to reciprocate along its own axis, and the second driven wheel 724 can drive the rotating shaft 203 to rotate, so that the pushing block 21 is fixed in the tensioning sleeve 201, and thus the driving shaft 204 is driven to rotate, so that the driving shaft 204 can move axially and also rotate. Through the above manner, the second roller 744 can roll in the slot of the connector 745, so that friction can be reduced, and further, axial movement and rotational movement of the driving shaft 204 can be free from interference.

Optionally, referring to fig. 6, the tensioning shaft 20 may further include an end cap 207. The end cover 207 is located at one end of the tensioning sleeve 201 far away from the rotating shaft 203, and the end cover 207 and the tensioning sleeve 201 are fixedly connected to seal the tensioning sleeve 201. The end cap 207 may also have a positioning groove 208. The positioning groove 208 is used for interfacing with other mechanisms (such as a discharging shaft and the like) to realize charging and discharging. The opening width of the positioning groove 208 is gradually reduced in the direction approaching the rotation axis 203, but may be kept constant. As long as it can meet the requirement of interfacing with other mechanisms.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
