Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slitting machine, in particular to an automatic winding device of slitting machine. BACKGROUND

[0002] The slitting machine is an automatic slitting device for cutting wide materials into multiple narrow materials. During the operation of the slitting machine, a plurality of winding assemblies arranged side by side are needed to wind the cut materials, and the cut materials are wound into a plurality of cut winding film rolls. The winding assembly of the slitting machine generally includes two winding arms provided with winding chucks. One of the winding arms is a driving winding arm, and the other is a non-driving winding arm. The winding chucks on the two winding arms are coaxially arranged. The winding chucks are rotatably arranged on the upper part of the winding arms. The driving winding arm is provided with a motor to drive the corresponding winding chuck to rotate. The winding chuck of the non-driving winding arm is not driven by power. The winding arms are slidably arranged on the guide rails of the machine frame. The winding arms are slid along the guide rails by a manual pushing mode or a driving mode by an electric actuator. The winding arms are usually provided with locking mechanisms, such as locking mechanisms formed by locking bolts, to lock and fix the winding arms on the machine frame.

[0003] In actual application, the two winding arms of the winding assembly are moved to clamp the winding core between the winding chucks on the two winding arms. The winding chucks are inserted into the inner holes at both ends of the winding core. Then, the locking mechanism is locked and fixed on the machine frame. Then, the motor on the driving winding arm drives the winding chuck to rotate, driving the winding core to rotate, and winding the cut materials. After the winding of a winding film roll is completed, the slitting machine and the winding assembly stop working. The locking mechanism is first loosened, and then the two winding arms of the winding assembly are separated by moving the two winding arms. Then, the completed winding film roll is removed. The cycle is repeated. For example, the Chinese patent CN210619682U discloses an automatic counter-station winding arm of a slitting machine, which includes a base and a winding arm. The base is provided with a guide rail. The winding arm is slidably connected to the guide rail. The base is provided with a rack parallel to the guide rail. The winding arm is further provided with a locking device cooperating with the rack to lock the winding arm and the rack. The winding arm can be locked with the rack by the locking device to prevent the displacement of the winding arm. The winding core is clamped or the winding film roll is removed by moving the winding arm along the guide rail.

[0004] The present application discloses a kind of automatic winding device of slitting machine, including winding assembly, it includes:

[0005] On the other hand, since the two winding arms of the current winding assembly are independently sliding on the guide rail, there may be a gap or installation error between the winding arm and the guide rail, which makes the coaxiality of the winding chuck on the two winding arms of the same winding assembly poor, resulting in the winding chuck on the two winding arms rotating the winding core barrel. During the winding process of the slitted material, the film roll is prone to large round runout, affecting the winding quality of the film roll (including affecting the winding density of the film roll and the flatness of the two ends of the film roll). SUMMARY

[0006] The first object of the present application is to provide an automatic winding device for a slitting machine that can facilitate the installation of the winding core barrel and the disassembly of the wound film roll without affecting the normal operation of the winding assembly, simplifying the operation steps and improving the slitting production efficiency. And it is beneficial to improve the layout compactness between the winding assemblies.

[0007] The second object of the present application based on the first object is to provide an automatic winding device for a slitting machine that can effectively improve the coaxiality of the winding chuck on the two winding arms of the same winding assembly, thereby effectively solving the problem of poor coaxiality of the winding chuck on the two winding arms of the same winding assembly, which causes the film roll to be prone to large round runout during the winding process, affecting the winding quality of the film roll.

[0008] The technical solution of the present application is:

[0009] An automatic winding device for a slitting machine, comprising a winding assembly, which includes:

[0010] Two winding arms provided with winding chucks, the winding arms are slidingly arranged on the rack of the slitting machine;

[0011] A locking mechanism for locking the winding arms on the rack;

[0012] One of the winding arms is provided with a chuck translation mechanism and a winding drive mechanism, the chuck translation mechanism comprises:

[0013] The outer sleeve is rotationally arranged on the winding arm, and the inner wall of the outer sleeve is provided with a spiral groove.

[0014] The inner sleeve is axially slidably arranged in the outer sleeve, and the inner sleeve is coaxially arranged in the outer sleeve, and the inner sleeve is provided with a matching pin which extends into the spiral groove.

[0015] The handle is fixed on the outer sleeve to drive the rotation of the outer sleeve.

[0016] The inner sleeve is rotationally arranged on the winding arm, and the inner sleeve is coaxially arranged in the outer sleeve, and the inner sleeve is provided with a matching pin which extends into the spiral groove.

[0017] In actual production process, according to the width of the film roll to be wound (the width of the film roll to be wound in the same production batch is consistent, i.e. the width of the film roll to be wound in the same production batch is consistent), the two winding arms of the winding assembly are moved to adjust the distance between the two winding arms of the winding assembly; then, the winding arms are locked and fixed on the rack by the locking mechanism. After that, the film roll winding operation of the same production batch is as follows,

[0018] First, drive the corresponding winding chuck in the winding assembly to move through the chuck translation mechanism, so that the winding chucks on the two winding arms in the same winding assembly are separated from each other. Specifically, the outer sleeve is driven to rotate (for example, the handle drives the outer sleeve to rotate clockwise by a set angle), and during the rotation of the outer sleeve, the matching pin on the inner sleeve cooperates with the spiral groove on the outer sleeve to drive the inner sleeve, the central shaft and the corresponding winding chuck to translate axially along the outer sleeve, so that the distance between the winding chucks on the two winding arms in the same winding assembly is increased, so that the winding core can be placed between the winding chucks of the two winding arms of the winding assembly, or the wound film roll can be taken out from between the winding chucks of the two winding arms.

[0019] Second, place the winding core between the winding chucks on the two winding arms.

[0020] Then, the corresponding winding chuck in the winding assembly is driven to move by the chuck translation mechanism, so that the winding chucks on the two winding arms in the same winding assembly are close to each other; specifically, the outer sleeve is driven to rotate (for example, the outer sleeve is counterclockwise rotated by a set angle) by the handle, and in the process of rotating the outer sleeve, the inner sleeve, the center shaft and the corresponding winding chuck are driven to translate axially along the outer sleeve by the cooperation of the helical groove on the outer sleeve and the matching pin on the inner sleeve, so that the winding chucks on the two winding arms in the same winding assembly are close to each other, thereby clamping the winding core between the winding chucks on the two winding arms, and the winding chucks extend into the inner holes at both ends of the winding core.

[0021] Then, the center shaft is driven to rotate by the winding drive mechanism, thereby driving the winding chucks and the winding core to rotate, and the cut material is wound.

[0022] Thirdly, after the winding of a film roll is completed, the slitting machine and the winding assembly stop working; then, the first step is returned, and the wound film roll is removed.

[0023] Fourthly, the second step is returned, and the cycle is repeated. In this way, during the winding operation of the film roll of the same production batch, only the outer sleeve is driven to rotate by a set angle by the handle of the chuck translation mechanism to drive the corresponding winding chuck in the winding assembly to move, so that the winding chucks on the two winding arms in the same winding assembly are separated or close to each other, thereby completing the installation of the winding core and the removal of the wound film roll, without the need to loosen or lock the winding arms by operating the locking mechanism, and without the need to move the winding arms, so that the operation process can be simplified without affecting the normal work of the winding assembly, the installation of the winding core and the removal of the wound film roll are facilitated, and the slitting production efficiency is improved.

[0024] On the other hand, during the winding operation of the film roll of the same production batch, the winding arms do not need to be moved, so that space is left for the movement of the winding arms when the winding core is installed or the film roll is removed, so that the winding arms of the two adjacent winding assemblies can be close to or even close to each other, thereby improving the layout compactness between the winding assemblies.

[0025] Preferably, the winding assembly further comprises a positioning mechanism, which comprises:

[0026] A positioning groove is arranged on the same part of the two winding arms, and the positioning groove is parallel to the rotation axis of the winding chuck;

[0027] A straight positioning rod cooperates with the positioning groove,

[0028] The pressing device is arranged on each of the two winding arms, and the pressing device simultaneously presses and fixes the straight positioning rod in the positioning groove of the two winding arms, so as to ensure coaxial distribution of the winding chucks on the two winding arms. In this way, the positions of the two winding arms of the same winding assembly can be corrected by cooperation of the straight positioning rod and the positioning grooves on the two winding arms of the same winding assembly, coaxial distribution of the winding chucks on the two winding arms is ensured, the stability of the film roll in the winding process is improved, the winding quality of the film roll is improved, and the cooperation gap or installation error between the winding arm and the guide rail is effectively solved. The coaxiality of the winding chucks on the two winding arms of the same winding assembly is poor, the winding chucks on the two winding arms drive the winding core to rotate, and the film roll is prone to have large round runout in the process of winding the slit material, thereby affecting the winding quality of the film roll (including affecting the winding density of the film roll and the flatness of both ends of the film roll).

[0029] Preferably, the positioning groove is semicircular, and the pressing device comprises:

[0030] The pressing plate is rotationally arranged on the winding arm.

[0031] The locking bolt locks the pressing plate on the winding arm, and the pressing plate presses the straight positioning rod in the positioning groove. In this way, the operation of the pressing device is facilitated.

[0032] Preferably, the winding assembly further comprises a linkage mechanism arranged on the same winding arm as the chuck translation mechanism, and the linkage mechanism comprises:

[0033] The linkage swing rod is rotationally arranged on the winding arm, and the winding arm is provided with a limiting piece.

[0034] The limiting rod is axially slidably arranged on the winding arm.

[0035] The connecting rope connects the limiting rod and the linkage swing rod.

[0036] The first elastic member drives the limiting rod to move and drives the linkage swing rod to rotate upward and abut against the limiting piece through the connecting rope. At this time, a part of the linkage swing rod is located in the positioning groove, and the limiting rod extends into the handle movement track to limit the rotation angle of the handle driving the outer sleeve.

[0037] When the pressing device presses and fixes the straight positioning rod in the positioning groove, the straight positioning rod abuts against the linkage swing rod and pushes the linkage swing rod to rotate. In this process, the linkage swing rod drives the limiting rod to move to the outside of the handle movement track through the connecting rope, thereby releasing the restriction on the handle driving outer sleeve. Since the straight positioning rod of the alignment mechanism is not installed, the winding assembly can still perform winding operation. Therefore, in the actual operation process, the operator may forget to install the straight positioning rod or intentionally not install the straight positioning rod, which causes the alignment mechanism to fail and affects the winding quality of the film roll. In order to solve this problem, the linkage mechanism is specially arranged, and specifically,

[0038] In the actual operation process, if the operator does not install the straight positioning rod of the alignment mechanism, at this time, the limiting rod extends into the handle movement track under the action of the first elastic member, thereby blocking the handle and limiting the rotation angle of the handle driving outer sleeve. In this way, the operator cannot rotate the handle driving outer sleeve by a sufficient angle, cannot drive the inner sleeve, the central shaft and the corresponding winding chuck to move axially along the outer sleeve to the specified position, and the winding core barrel cannot be smoothly placed between the winding chucks of the two winding arms of the winding assembly. Therefore, the operator is forced to install the straight positioning rod of the alignment mechanism, thereby effectively solving the problem that the operator does not install the straight positioning rod of the alignment mechanism, which causes the alignment mechanism to fail and affects the winding quality of the film roll.

[0039] When the pressing device presses and fixes the straight positioning rod in the positioning groove, the straight positioning rod abuts against the linkage swing rod and pushes the linkage swing rod to rotate. In this process, the linkage swing rod drives the limiting rod to move to the outside of the handle movement track through the connecting rope, thereby releasing the restriction on the handle driving outer sleeve. Therefore, as long as the operator installs the straight positioning rod of the alignment mechanism according to the installation specification, the normal work of the chuck translation mechanism will not be affected.

[0040] Preferably, an installation sleeve is arranged at the upper part of the winding arm on which the outer sleeve is arranged, and the outer sleeve is rotatably arranged in the installation sleeve. The chuck translation mechanism further comprises an arc-shaped groove arranged on the side wall of the installation sleeve, which extends circumferentially around the installation sleeve. The handle extends radially relative to the outer sleeve, and the handle passes through the arc-shaped groove. In this way, the rotation angle of the handle can be limited by the arc-shaped groove, thereby facilitating accurate control of the movement distance of the winding chuck in the actual operation.

[0041] Preferably, the chuck translation mechanism further comprises a locking mechanism, which comprises:

[0042] A locking sleeve is arranged on the handle, and the locking sleeve is located outside the installation sleeve;

[0043] A second elastic member is arranged to drive the locking sleeve to move and abut against the outer side surface of the installation sleeve;

[0044] A locking groove is arranged on the outer side surface of the installation sleeve at one end of the arc-shaped groove.

[0045] When the handle moves to one end of the arc-shaped groove, the winding chuck of the two winding arms of the same winding assembly are close to each other to clamp the winding core between the winding chucks on the two winding arms, and the locking sleeve is clamped into the locking groove under the action of the second elastic member to lock the handle position.

[0046] During the winding operation of the winding assembly, the worker may accidentally touch the handle to drive the outer sleeve to rotate, which increases the distance between the winding chucks on the two winding arms in the same winding assembly, causes the film roll to loosen, and affects the winding quality of the film roll. In order to solve this problem, the locking mechanism is specially provided. When the handle moves to one end of the arc-shaped groove to clamp the winding core between the winding chucks on the two winding arms, the locking sleeve is clamped into the locking groove under the action of the second elastic member to lock the handle position. In this way, during the winding operation of the winding assembly, even if the worker accidentally touches the handle, the handle will not drive the outer sleeve to rotate; thus, the problem that the worker accidentally touches the handle to drive the outer sleeve to rotate, which increases the distance between the winding chucks on the two winding arms in the same winding assembly, causes the film roll to loosen, and affects the winding quality of the film roll can be effectively solved.

[0047] Preferably, the chuck translation mechanism further comprises an axial guide groove provided on the outer wall of the inner sleeve and a clamping block fixedly provided on the winding arm, and the clamping block extends into the axial guide groove. In this way, it is ensured that the inner sleeve can only slide axially along the outer sleeve and cannot rotate.

[0048] Preferably, the winding drive mechanism comprises:

[0049] A rotating member is rotatably provided on the outer sleeve or the winding arm, comprising a driving sleeve, the driving sleeve is slidably sleeved on the central shaft, and the driving sleeve and the central shaft cannot rotate relative to each other, and the rotation axis of the rotating member, the driving sleeve and the inner sleeve are coaxial;

[0050] A motor drives the rotating member to rotate. In this way, the motor can drive the rotating member to rotate, and the central shaft and the corresponding winding chuck are driven to rotate by the driving sleeve; at the same time, the movement of the inner sleeve central shaft and the corresponding winding chuck driven by the chuck translation mechanism is not affected.

[0051] Preferably, the motor is located between the two winding arms of the same winding assembly, the motor is fixed to the lower part of one of the winding arms, the other winding arm is provided with a avoiding groove, the slot of the avoiding groove faces the motor, and the motor can extend into the avoiding groove.

[0052] Since the motor is located between the two winding arms of the same winding assembly, the winding arms of the two adjacent winding assemblies can be close to each other or even tightly close to each other, thereby improving the layout compactness between the winding assemblies. Meanwhile, since the other winding arm is provided with the avoiding groove, the groove opening of the avoiding groove faces the motor, and the motor can extend into the avoiding groove, so that the two winding arms of the same winding assembly can be closer, thereby enabling the winding of the film roll with smaller width between the two winding arms of the winding assembly to adapt to the winding of the film roll with smaller width.

[0053] As preferred, the rack is provided with horizontally distributed guide rails, the winding assemblies are multiple, each winding assembly is sequentially distributed along the guide rails, the winding arms slide along the guide rails, and the locking mechanism comprises a locking screw threadedly connected to the lower part of the winding arm.

[0054] The present application has the following beneficial effects:

[0055] Firstly, during the winding operation of the film roll of the same production batch, only the handle of the chuck translation mechanism is needed to drive the outer sleeve to rotate to set the angle, to drive the corresponding winding chuck in the winding assembly to move, so that the winding chucks on the two winding arms in the same winding assembly are separated or close to each other, thereby completing the installation of the winding core barrel and the disassembly of the winding film roll, without the need to operate the locking mechanism to loosen or lock the winding arm, and without the need to move the winding arm, so that the normal work of the winding assembly is not affected, the operation process steps are simplified, the installation of the winding core barrel and the disassembly of the winding film roll are facilitated, and the slitting production efficiency is improved.

[0056] Secondly, since the winding arm does not need to be moved during the winding operation of the film roll of the same production batch, the space for moving the winding arm is left out, thereby improving the layout compactness between the winding assemblies.

[0057] Thirdly, the positions of the two winding arms of the same winding assembly can be corrected by cooperating the same straight positioning rod with the positioning grooves on the two winding arms of the same winding assembly, to ensure the coaxial distribution of the winding chucks on the two winding arms, improve the stability of the film roll during winding, thereby improving the winding quality of the film roll, effectively solving the cooperation gap or installation error between the winding arm and the guide rail, so that the coaxiality of the winding chucks on the two winding arms of the same winding assembly is poor, the winding chucks on the two winding arms drive the winding core barrel to rotate, the film roll is easily large in round runout during the winding of the slit material, and the winding quality of the film roll is affected (including affecting the winding compactness of the film roll and the flatness of both ends of the film roll).

[0078] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0079] Specific Implementation Example 1, such as Figures 1-7 As shown, an automatic winding device for a slitting machine includes a winding assembly 2. The winding assembly 2 includes two winding arms 2.1 equipped with winding clamps 2.0 and a locking mechanism 2.2. One of the winding arms 2.1 in the winding assembly 2 is equipped with a clamp translation mechanism 2.3 and a winding drive mechanism 2.4.

[0080] The winding chuck 2.0 is rotatably mounted on the winding arm 2.1. The winding chucks 2.0 on the two winding arms 2.1 are coaxially distributed. The winding chucks 2.0 correspond one-to-one with the winding arms 2.1. The winding chucks 2.0 in the same winding assembly 2 are located between the two winding arms 2.1.

[0081] Both take-up arms 2.1 of the take-up assembly 2 are slidably mounted on the frame 1 of the slitting machine. The locking mechanism 2.2 is used to lock the take-up arms 2.1 onto the frame 1. The rotation axis of the take-up chuck 2.0 is parallel to the sliding direction of the take-up arms 2.1.

[0082] The chuck translation mechanism 2.3 includes an outer sleeve 2.32, an inner sleeve 2.33, and a handle 2.31.

[0083] The outer sleeve 2.32 is rotatably mounted on the take-up arm 2.1. The rotation axis of the outer sleeve 2.32 is parallel to the sliding direction of the take-up arm 2.1. The inner wall of the outer sleeve 2.32 is provided with a spiral groove 2.310, which extends spirally along the axial direction of the outer sleeve 2.32.

[0084] The handle 2.31 is fixed to the outer cover 2.32, and the handle 2.31 is used to drive the outer cover 2.32 to rotate.

[0085] The inner sleeve 2.33 slides axially along the outer sleeve 2.32. The inner sleeve 2.33 can only slide axially along the outer sleeve 2.32 and cannot rotate. The inner sleeve 2.33 is coaxially disposed within the outer sleeve 2.32. The inner sleeve 2.33 is provided with a mating pin 2.311, which extends into the spiral groove 2.310.

[0086] The inner sleeve 2.33 is provided with a central shaft 2.34 rotating therein. The central shaft 2.34 is coaxially distributed with the inner sleeve 2.33. The central shaft 2.34 is rotatingly provided in the inner sleeve 2.33 through a bearing. The winding chuck 2.0 on the winding arm 2.1 where the inner sleeve 2.33 is located is fixed on the central shaft 2.34. In this embodiment, the winding chuck 2.0 on the winding arm 2.1 where the inner sleeve 2.33 is located is fixed on the end face of the central shaft 2.34 through a bolt. Of course, the winding chuck 2.0 on the winding arm 2.1 where the inner sleeve 2.33 is located can also be fixed on the central shaft 2.34 in other ways, for example, the winding chuck 2.0 can also be fixed on the central shaft 2.34 through welding and clamping.

[0087] The winding drive mechanism 2.4 drives the rotation of the central shaft 2.34, thereby driving the rotation of the winding chuck 2.0 on the central shaft 2.34.

[0088] The specific use of the automatic winding device of the slitting machine in this embodiment is as follows,

[0089] In actual production process, according to the width of the film roll to be wound (the slitting width of the film roll of the same production batch is consistent, that is, the width of the film roll to be wound in the same production batch is consistent), the two winding arms 2.1 of the winding assembly 2 are moved to adjust the distance between the two winding arms 2.1 of the winding assembly 2; then, the winding arm 2.1 is locked and fixed on the rack 1 through the locking mechanism. Thereafter, the film roll winding operation of the same production batch is as follows (hereinafter one of the winding assemblies 2 is taken as an example for description),

[0090] Firstly, the corresponding winding chuck 2.0 in the winding assembly 2 is driven to move by the chuck translation mechanism 2.3, so that the winding chucks 2.0 on the two winding arms 2.1 in the same winding assembly 2 are separated from each other. Specifically, the outer sleeve 2.32 is driven to rotate by the handle 2.31 (for example, the handle 2.31 drives the outer sleeve 2.32 to rotate clockwise by a set angle), and in the process of rotating the outer sleeve 2.32, the outer sleeve 2.32 is matched with the matching pin 2.311 on the inner sleeve 2.33 through the spiral groove 2.310 on the outer sleeve 2.32, so as to drive the inner sleeve 2.33, the central shaft 2.34 and the corresponding winding chuck 2.0 to translate along the axial direction of the outer sleeve 2.32, so that the distance between the winding chucks 2.0 on the two winding arms 2.1 in the same winding assembly 2 is increased, so that the winding core can be put between the winding chucks 2.0 of the two winding arms 2.1 of the winding assembly 2, or the winding film roll after winding can be taken out from between the winding chucks 2.0 of the two winding arms 2.1.

[0091] Secondly, the winding core 3 is placed between the winding chucks 2.0 on the two winding arms 2.1;

[0092] Then, as Figures 1-7As shown, the two winding chucks 2.0 on the two winding arms 2.1 of the same winding assembly 2 are moved closer to each other by driving the corresponding winding chuck 2.0 in the winding assembly 2 to move through the chuck translation mechanism 2.3. Specifically, the sleeve 2.32 is driven to rotate by the handle 2.31 (for example, the sleeve 2.32 is driven to rotate counterclockwise by a set angle by the handle 2.31), and during the rotation of the sleeve 2.32, the sleeve 2.32 is matched with the matching pin 2.311 on the inner sleeve 2.33 through the helical groove 2.310 on the sleeve 2.32 to drive the inner sleeve 2.33, the central shaft 2.34 and the corresponding winding chuck 2.0 to translate along the sleeve 2.32 in the axial direction, so that the two winding chucks 2.0 on the two winding arms 2.1 of the same winding assembly 2 are moved closer to each other, thereby clamping the winding core barrel 3 between the two winding chucks 2.0 on the two winding arms 2.1, and the winding chuck 2.0 extends into the inner hole of the two ends of the winding core barrel 3.

[0093] Then, the winding drive mechanism 2.4 drives the central shaft 2.34 to rotate, thereby driving the winding chuck 2.0 and the winding core barrel to rotate, and the cut material is wound.

[0094] Thirdly, after the winding of the film roll is completed, the slitting machine and the winding assembly 2 stop working; then, return to the first step, and remove the wound film roll.

[0095] Fourthly, return to the second step, and repeat the above steps. In this way, during the winding operation of the film roll of the same production batch, only the handle 2.31 of the chuck translation mechanism 2.3 is needed to drive the sleeve 2.32 to rotate by a set angle to drive the corresponding winding chuck 2.0 in the winding assembly 2 to move, so that the two winding chucks 2.0 on the two winding arms 2.1 of the same winding assembly 2 are separated or moved closer to each other, thereby completing the installation of the winding core barrel and the removal of the wound film roll, without the need to operate the locking mechanism 2.2 to loosen or lock the winding arms 2.1, and without the need to move the winding arms 2.1, so that the operation process steps can be simplified without affecting the normal working of the winding assembly 2, the installation of the winding core barrel and the removal of the wound film roll are facilitated, and the slitting production efficiency is improved.

[0096] On the other hand, during the winding operation of the film roll of the same production batch, the winding arms 2.1 do not need to be moved, so that the space for moving the winding arms 2.1 is left out for the installation of the winding core barrel or the removal of the film roll, and the winding arms 2.1 of the adjacent two winding assemblies 2 can be moved closer to each other or even close to each other, thereby improving the layout compactness between the winding assemblies 2.

[0097] Specifically, as shown in Figure 1 , Figure 2 The machine frame 1 is provided with horizontally distributed guide rails 1.1. The winding assemblies 2 are multiple. The winding assemblies 2 are distributed side by side along the guide rails 1.1 in sequence. The winding arms 2.1 of the winding assemblies 2 slide along the guide rails 1.1.

[0098] Each winding arm 2.1 is provided with a locking mechanism 2.2. In the embodiment, the locking mechanism 2.2 comprises a locking screw 2.21 screwed on the lower part of the winding arm 2.1. By tightening the locking screw 2.21, the locking screw 2.21 is abutted against the rack 1, so that the winding arm 2.1 is locked on the rack 1. The locking screw 2.21 is further provided with a driving handle or hand wheel, by which the locking screw 2.21 is tightened or loosened, so as to facilitate the actual operation. Of course, the locking mechanism 2.2 can also adopt other structures, for example, the locking mechanism 2.2 adopts a pneumatic cylinder or an electric cylinder, and the winding arm 2.1 is locked on the rack 1 by abutting the piston rod of the pneumatic cylinder or the electric cylinder against the rack 1. Or the locking mechanism 2.2 adopts an electromagnet, and the winding arm 2.1 is locked on the rack 1 by energizing the electromagnet.

[0099] In the embodiment, as shown in Figure 5 The chuck translation mechanism 2.3 further comprises an axial guide groove 2.39 provided on the outer wall of the inner sleeve 2.33 and a clamping block 2.38 fixedly provided on the winding arm 2.1, and the axial guide groove 2.39 extends along the axial direction of the inner sleeve 2.33. The clamping block 2.38 is fixed on the winding arm 2.1 by bolts. The clamping block 2.38 extends into the axial guide groove 2.39. In this way, it is ensured that the inner sleeve 2.33 can only slide along the axial direction of the outer sleeve 2.32, and the inner sleeve 2.33 cannot rotate.

[0100] Further, as shown in Figures 1-4 The winding drive mechanism 2.4 comprises a rotating member 2.42 and a motor 2.41. The rotating member 2.42 is rotatably arranged on the outer sleeve 2.32 or the winding arm 2.1. In the embodiment, the rotating member 2.42 is rotatably arranged on the outer sleeve 2.32 through a bearing. The rotating member 2.42 comprises a driving sleeve 2.43. The driving sleeve 2.43 is integrated with the rotating member 2.42. The driving sleeve 2.43 is slidably sleeved on the central shaft 2.34. The driving sleeve 2.43 and the central shaft 2.34 cannot rotate relative to each other. The rotation axis of the rotating member 2.42, the driving sleeve 2.43 and the inner sleeve 2.33 are coaxial. The motor 2.41 is fixed on the winding arm 2.1, and the motor 2.41 drives the rotating member 2.42 to rotate. In this way, the motor 2.41 can drive the rotating member 2.42 to rotate, and the central shaft 2.34 and the corresponding winding chuck 2.0 are driven to rotate by the driving sleeve 2.43; at the same time, the movement of the inner sleeve 2.33, the central shaft 2.34 and the corresponding winding chuck 2.0 driven by the chuck translation mechanism 2.3 is not affected.

[0101] The driving sleeve 2.43 is not rotatable relative to the central shaft 2.34. Specifically, the central shaft 2.34 and the driving sleeve 2.43 are provided with an axially extending key groove and a protruding key matched with the key groove, respectively, so that the driving sleeve 2.43 is not rotatable relative to the central shaft 2.34. For example, the central shaft 2.34 is a spline shaft including a plurality of protruding keys; the inner hole of the driving sleeve 2.43 is a spline hole including a plurality of key grooves; the spline shaft and the spline hole are matched, so that the driving sleeve 2.43 is slidably sleeved on the central shaft 2.34, and the driving sleeve 2.43 is not rotatable relative to the central shaft 2.34.

[0102] In an example, the winding driving mechanism 2.4 further includes a belt transmission mechanism, and the rotating member 2.42 is driven by the belt transmission mechanism relative to the output shaft of the motor 2.41. The belt transmission mechanism includes a driving pulley and a driven pulley, wherein the driving pulley is connected with the output shaft of the motor 2.41. The driven pulley is fixedly connected with the rotating member 2.42; or the driven pulley constitutes the rotating member 2.42.

[0103] In another example, the winding driving mechanism 2.4 further includes a gear transmission mechanism, and the rotating member 2.42 is driven by the gear transmission mechanism relative to the output shaft of the motor 2.41. The gear transmission mechanism includes a driving gear and a driven gear, wherein the driving gear is connected with the output shaft of the motor 2.41. The driven gear is fixedly connected with the rotating member 2.42; or the driven gear constitutes the rotating member 2.42.

[0104] Further, as shown in Figure 1 、 Figure 3 、 Figure 7 , the motor 2.41 is located between the two winding arms 2.1 of the same winding assembly 2. The motor 2.41 is fixed on the lower part of one of the winding arms 2.1, and the other winding arm 2.1 is provided with an avoiding slot, the slot opening of the avoiding slot faces the motor 2.41, and the motor 2.41 can extend into the avoiding slot. Since the motor 2.41 is located between the two winding arms 2.1 of the same winding assembly 2, the winding arms 2.1 of the adjacent two winding assemblies 2 can be close to each other or even tightly close to each other, thereby improving the layout compactness between the winding assemblies 2. At the same time, since the other winding arm 2.1 is provided with the avoiding slot, the slot opening of the avoiding slot faces the motor 2.41, and the motor 2.41 can extend into the avoiding slot, so that the two winding arms 2.1 of the same winding assembly 2 can be closer, thereby enabling the film roll with smaller width to be wound between the two winding arms 2.1 of the winding assembly 2 to adapt to the winding of the film roll with smaller width.

[0105] Further, as shown in Figure 1 、 Figure 4 、 Figure 5As shown in the figure, the upper part of the winding arm 2.1 where the outer sleeve 2.32 is located is provided with a mounting sleeve 2.11. The outer sleeve 2.32 is rotatably arranged in the mounting sleeve 2.11. The chuck translation mechanism 2.3 further comprises an arc-shaped groove 2.12 arranged on the side wall of the mounting sleeve 2.11. The arc-shaped groove 2.12 extends circumferentially around the mounting sleeve 2.11, and the arc-shaped groove 2.12 communicates the inner and outer side walls of the mounting sleeve 2.11. The handle 2.31 extends radially along the outer sleeve 2.32. The handle 2.31 passes through the arc-shaped groove. In this way, the rotation angle of the handle 2.31 can be limited by the arc-shaped groove 2.12, which facilitates accurate control of the movement distance of the winding chuck 2.0 in actual operation.

[0106] Further, as shown in the figure, Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 The chuck translation mechanism 2.3 further comprises a locking mechanism. The locking mechanism comprises a locking sleeve 2.35, a second elastic member 2.36, and a locking groove 2.37. The locking sleeve 2.35 is slidably sleeved on the handle 2.31. The locking sleeve 2.35 is located outside the mounting sleeve 2.11. The second elastic member 2.36 drives the locking sleeve 2.35 to move and abuts against the outer side surface of the mounting sleeve 2.11. In this embodiment, one end of the handle 2.31 is fixedly connected with the outer sleeve 2.32, and the other end of the handle 2.31 is provided with a stop block. A stepped surface is arranged on the inner wall of the locking sleeve 2.35. The second elastic member 2.36 is a second compression spring, which is sleeved on the handle 2.31 and abuts between the stop block and the stepped surface. The locking groove 2.37 is arranged on the outer side surface of the mounting sleeve 2.11 at one end of the arc-shaped groove.

[0107] When the handle 2.31 moves to one end of the arc-shaped groove, the winding chucks 2.0 of the two winding arms 2.1 of the same winding assembly 2 are close to each other, so as to clamp the winding core between the winding chucks 2.0 on the two winding arms 2.1, and the locking sleeve 2.35 is clamped into the locking groove 2.37 under the action of the second elastic member 2.36, so as to lock the position of the handle 2.31.

[0108] During the winding operation of the winding assembly 2, the handle 2.31 may be accidentally touched by the operator, causing the outer sleeve 2.32 to rotate, the distance between the winding chucks 2.0 on the two winding arms 2.1 in the same winding assembly 2 to increase, and the film roll to loosen, thereby affecting the winding quality of the film roll. In order to solve this problem, the locking mechanism is specially provided in this scheme, and specifically,

[0109] When the handle 2.31 drives the outer sleeve 2.32 to rotate, and the handle 2.31 is moved to one end of the arc-shaped slot, the winding chuck 2.0 on the two winding arms 2.1 in the same winding assembly 2 are close to each other, and the winding core cylinder is clamped between the winding chucks 2.0 on the two winding arms 2.1, at the same time, the locking sleeve 2.35 is clamped into the locking slot 2.37 under the action of the second elastic element 2.36, so as to lock the position of the handle 2.31. In this way, during the winding operation of the winding assembly 2, even if the operator accidentally touches the handle 2.31, the handle 2.31 will not drive the outer sleeve 2.32 to rotate; thus, the problem that the distance between the winding chucks 2.0 on the two winding arms 2.1 in the same winding assembly 2 is increased due to the accidental touch of the handle 2.31 by the operator, the rotation of the outer sleeve 2.32, and the loosening of the film roll, which affects the winding quality of the film roll, can be effectively solved.

[0110] When the winding of one film roll is completed, the slitting machine and the winding assembly 2 stop working; then, the operator moves the locking sleeve 2.35 along the handle 2.31 out of the locking slot 2.37, and then drives the outer sleeve 2.32 to rotate through the handle 2.31, so that the distance between the winding chucks 2.0 on the two winding arms 2.1 in the same winding assembly 2 is increased, and the completed winding film roll can be taken out from between the winding chucks 2.0 of the two winding arms 2.1.

[0111] In the second embodiment, the remaining structures of the embodiment are the same as those of the first embodiment, and the difference lies in that,

[0112] As shown in Figure 1 , Figure 2 , the winding assembly 2 further comprises a positioning mechanism 2.5. The positioning mechanism 2.5 comprises a positioning slot 2.51, a straight positioning rod 2.50 matched with the positioning slot 2.51, and a pressing device.

[0113] The same part of the two winding arms 2.1 of the same winding assembly 2 is provided with the positioning slot 2.51. The positioning slot 2.51 is a through slot. The positioning slot 2.51 is parallel to the rotation axis of the winding chuck 2.0 (not shown in the figure). Figure 1 In the embodiment, the positioning slot 2.51 is semicircular, and the straight positioning rod 2.50 corresponds to a circular rod.

[0114] The two winding arms 2.1 are each provided with the pressing device. The pressing device simultaneously presses and fixes the straight positioning rod 2.50 in the positioning slot 2.51 of the two winding arms 2.1 of the same winding assembly 2, so as to ensure that the winding chucks 2.0 on the two winding arms 2.1 are coaxially distributed.

[0115] In this embodiment, the positions of the two winding arms 2.1 of the same winding assembly 2 are corrected by the cooperation of the same linear positioning rod 2.50 with the positioning grooves 2.51 on the two winding arms 2.1 of the same winding assembly 2. This ensures that the winding chucks 2.0 on the two winding arms 2.1 are coaxially distributed, improving the stability of the film roll during the winding process and thus improving the winding quality of the film roll. This effectively solves the problem of poor coaxiality of the winding chucks 2.0 on the two winding arms 2.1 of the same winding assembly 2 due to the fit gap or installation error between the winding arm 2.1 and the guide rail 1.1. As a result, the winding chucks 2.0 on the two winding arms 2.1 drive the winding core cylinder to rotate, and the film roll is prone to large circular runout during the winding process of the slit material, which affects the winding quality of the film roll (including affecting the winding density of the film roll and the flatness of the two ends of the film roll).

[0116] In one example, the clamping device includes a pressure plate 2.52 and a locking bolt 2.53. The pressure plate 2.52 is rotatably mounted on the winding arm 2.1. The linear positioning rod 2.50 and the positioning groove 2.51 are located on the same side of the pressure plate. The locking bolt 2.53 locks the pressure plate onto the winding arm 2.1, and the pressure plate presses the linear positioning rod 2.50 into the positioning groove 2.51. This facilitates the operation of the clamping device.

[0117] Furthermore, the clamping device includes a return spring, which is sleeved on the locking bolt and located between the pressure plate and the winding arm 2.1. When the locking bolt is loosened, the pressure plate opens due to the return spring, facilitating the installation and removal of the linear positioning rod 2.50.

[0118] In another example, the clamping device includes a pressure plate and locking bolts. The linear positioning rod 2.50 and the positioning groove 2.51 are located on the same side of the pressure plate. The pressure plate is mounted on the winding arm 2.1 by the locking bolts, and the pressure plate presses the linear positioning rod 2.50 into the positioning groove 2.51. This facilitates the operation of the clamping device.

[0119] In this specific embodiment, the remaining structure is the same as in specific embodiment two, except that...

[0120] like Figure 8 , Figure 9 As shown, the winding assembly 2 also includes a linkage mechanism 2.6. The linkage mechanism 2.6 and the chuck translation mechanism 2.3 are mounted on the same winding arm 2.1.

[0121] The linkage mechanism 2.6 includes a linkage lever 2.61, a limiting lever 2.62, a connecting rope 2.63, and a first elastic element 2.64.

[0122] The linkage swing lever 2.61 is rotatably arranged on the winding arm 2.1, and the winding arm 2.1 is provided with a limiting piece 2.68. The limiting piece 2.68 is used for limiting the linkage swing lever 2.61. In the embodiment, the linkage mechanism 2.6 further comprises a containing groove 2.67, which is arranged on the winding arm 2.1 and communicates with the bottom surface of the positioning groove 2.51. The linkage swing lever 2.61 is rotatably arranged in the containing groove 2.67. The limiting piece 2.68 is arranged on the side wall of the containing groove 2.67, and the limiting piece 2.68 is located above the linkage swing lever 2.61.

[0123] The limiting rod 2.62 is axially slidably arranged on the winding arm 2.1 along the outer sleeve 2.32. In the embodiment, the linkage mechanism 2.6 further comprises a guide sleeve 2.65. The guide sleeve 2.65 is fixed on the winding arm 2.1 and close to the arc-shaped groove. The guide sleeve 2.65 extends axially along the outer sleeve 2.32, and the limiting rod 2.62 is slidably arranged in the guide sleeve 2.65.

[0124] The connecting rope 2.63 connects the limiting rod 2.62 and the linkage swing lever 2.61. In the embodiment, the linkage mechanism 2.6 further comprises one or more guide wheels 2.66, which are rotatably arranged on the winding arm 2.1. One end of the connecting rope 2.63 is connected with one end of the limiting rod 2.62, and the other end of the connecting rope 2.63 is sequentially wound around each guide wheel 2.66 and connected with the linkage swing lever 2.61.

[0125] The first elastic member 2.64 drives the limiting rod 2.62 to move, so that the connecting rope 2.63 is in a taut state, and the linkage swing lever 2.61 is driven by the connecting rope 2.63 to rotate upward and abut against the limiting piece 2.68. At this time, a part of the linkage swing lever 2.61 is located in the positioning groove 2.51, and the limiting rod 2.62 extends into the movement track of the handle 2.31 to limit the rotation angle of the outer sleeve 2.32 driven by the handle 2.31. Specifically, the first elastic member 2.64 is a first compression spring, which is located in the guide sleeve 2.65 and abuts between the limiting rod 2.62 and the end surface of the guide sleeve 2.65. The first compression spring drives the limiting rod 2.62 to extend into the arc-shaped groove. When the straight positioning rod 2.50 is not installed into the positioning groove 2.51, the first elastic member 2.64 drives the limiting rod 2.62 to move, so that the connecting rope 2.63 is in a taut state, and the linkage swing lever 2.61 is driven by the connecting rope 2.63 to rotate upward and abut against the limiting piece 2.68. At this time, a part of the linkage swing lever 2.61 is located in the positioning groove 2.51, and the limiting rod 2.62 extends into the arc-shaped groove to limit the rotation angle of the outer sleeve 2.32 driven by the handle 2.31.

[0126] When the pressing device presses and fixes the straight positioning rod 2.50 in the positioning groove 2.51, the straight positioning rod 2.50 abuts against the linkage swing rod 2.61 and pushes the linkage swing rod 2.61 to rotate, in the process, the linkage swing rod 2.61 drives the limiting rod 2.62 to move to the outside of the movement track of the handle 2.31 (the limiting rod 2.62 moves to the outside of the arc-shaped groove) through the connecting rope 2.63, and the restriction on the handle 2.31 driving the outer sleeve 2.32 is released.

[0127] Since the straight positioning rod 2.50 of the alignment mechanism 2.5 can be omitted even if it is not installed, the winding assembly 2 can still perform the winding operation, thus in the actual operation process, the operator may omit the installation of the straight positioning rod 2.50 due to unfamiliarity with the operation specification, or the straight positioning rod 2.50 may not be installed due to theft, which causes the alignment mechanism 2.5 to fail and affects the winding quality of the film roll. In order to solve this problem, the linkage mechanism 2.6 is specially provided, and specifically,

[0128] In the actual operation process, if the operator does not install the straight positioning rod 2.50 of the alignment mechanism 2.5, at this time, the limiting rod 2.62 extends into the movement track of the handle 2.31 under the action of the first elastic member 2.64, blocks the handle 2.31, and limits the rotation angle of the handle 2.31 driving the outer sleeve 2.32. In this way, the operator will not be able to drive the outer sleeve 2.32 to rotate by a sufficient angle through the handle 2.31, and will not be able to drive the inner sleeve 2.33, the central shaft 2.34 and the corresponding winding chuck 2.0 to axially translate along the outer sleeve 2.32 to the specified position, so that the winding core cannot be smoothly placed between the winding chucks 2.0 of the two winding arms 2.1 of the winding assembly 2; thereby forcing the operator to install the straight positioning rod 2.50 of the alignment mechanism 2.5, thereby effectively solving the problem that the alignment mechanism 2.5 fails and affects the winding quality of the film roll due to the operator not installing the straight positioning rod 2.50 of the alignment mechanism 2.5.

[0129] When the pressing device presses and fixes the straight positioning rod 2.50 in the positioning groove 2.51, the straight positioning rod 2.50 abuts against the linkage swing rod 2.61 and pushes the linkage swing rod 2.61 to rotate, in the process, the linkage swing rod 2.61 drives the limiting rod 2.62 to move to the outside of the movement track of the handle 2.31 (the limiting rod 2.62 moves to the outside of the arc-shaped groove) through the connecting rope 2.63, and the restriction on the handle 2.31 driving the outer sleeve 2.32 is released. Thus, as long as the operator installs the straight positioning rod 2.50 of the alignment mechanism 2.5 in a standard manner, the normal work of the chuck translation mechanism 2.3 will not be affected.

[0130] The above is only a preferred embodiment of the present application, and does not limit the present application in any way. Any simple modification, change and equivalent transformation of the above embodiment according to the technical essence of the present application still belongs to the protection scope of the technical solution of the present application.
