Description

Technical Field

[0001] The invention relates to the technical field of universal parts of machines, in particular to a slitting machine cone head. Background Art

[0002] Aluminum foil slitting machine is a high-performance aluminum foil finishing equipment, which can complete the slitting of large diameter aluminum foil rolls into two, and can also complete the trimming and rewinding of incoming large diameter aluminum foil rolls, realizing two functions of one machine. The process flow of aluminum foil slitting machine mainly includes unwinding, internal winding, slitting, external winding and other processes. The unwinding mechanism is an important part of the aluminum foil slitting unit. Its main function is to clamp the coil, realize the horizontal centering of the coil, and establish the unwinding tension. Figure 1 As shown, the structure of the unwinding mechanism mainly includes two clamping and centering cylinders 1, two boxes 2, two cone heads 4, and also includes a reduction box 7, a motor 8 and a base 9. The box 2 is slidably arranged on the base 9, and the clamping and centering cylinder 1 can drive the two boxes 2 to move relative to or away from each other. The cone head 4 is rotatably installed on the top of the box 2 through a support shaft, and a reduction box 7 and a motor 8 are provided on one side of one of the boxes. The motor 8 is used to drive the support shaft to rotate, thereby driving the cone head 4 to rotate, and the rotation of the cone head 4 can drive the aluminum foil roll 200 located between the two cone heads 4 to rotate. The aluminum foil roll 200 includes a reel 202 and aluminum foil wrapped around the outer periphery of the reel 202. The operation process of the unwinding mechanism is to use a crane to lift the aluminum foil roll 200 to the middle of the two cone heads 4 of the unwinding mechanism, and the clamping and centering cylinders 1 on both sides drive the box 2 to move toward the middle, and the cone heads 4 on both sides clamp the reel 202 to achieve horizontal centering of the aluminum foil roll. Then start the motor, the cone head drives the aluminum foil roll to rotate, and establishes the unwinding tension.

[0003] In the process of the cone heads on both sides moving toward the middle and clamping the roll of aluminum foil, since the cone heads and the roll are not aligned and there is a certain eccentric distance, the cone heads and the inner wall of the roll are only partially in contact at the beginning. At the same time, due to the large mass of the aluminum foil roll, a large friction force is generated between the surface of the cone heads and the inner wall of the roll. At the same time, as the cone heads on both sides continue to move toward the middle and clamp the roll, long-term use will cause greater wear on the cone heads and the roll, which will affect the alignment effect and further affect the subsequent slitting of the aluminum foil. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention proposes a slitting machine cone head to solve the technical problem in the prior art that the cone head and the reel are prone to significant wear and tear, thereby affecting the centering effect.

[0007] Furthermore, a mounting groove is provided on one side end face of the support ring, and one end of the support petal is slidably arranged in the mounting groove along the axial direction of the support ring. Elastic parts are respectively connected between each of the support petals and the support ring so that the support petal and the support ring are elastically floatingly connected together, and the support petal and the support ring are anti-rotationally matched so that the support petal can be driven to rotate synchronously when the support ring rotates.

[0008] Furthermore, a first keyway is provided on the outer circumferential surface of the support petal, and a first key is provided in the mounting groove of the support ring, and the first key cooperates with the first keyway to realize anti-rotation cooperation between the support petal and the support ring.

[0009] Furthermore, one end of each supporting petal located in the installation groove is connected to a guide column, a guide hole is opened in the installation groove, and the guide column is inserted into the guide hole.

[0010] Furthermore, the elastic member is a coil spring, each coil spring is respectively sleeved on the guide column, and the coil spring is located in the guide hole.

[0011] Furthermore, a spiral track groove extending along the circumferential direction of the support shaft is provided on the outer circumferential surface of the support shaft, and a sleeve coaxial with the support ring is provided on the side of the support ring away from the support petal, and a slider is connected to the side wall of the sleeve, and the slider is located in the spiral track groove. When the first driving mechanism drives the support ring to rotate, the slider slides along the extension direction of the spiral track groove to drive the support ring to move axially along the support shaft.

[0012] Furthermore, the end of the support shaft facing the reel is set as the first end, and the end away from the reel is set as the second end, and the pitch of the spiral track groove gradually decreases from the second end to the first end of the support shaft.

[0013] Furthermore, a transmission gear is provided on the sleeve, and the transmission gear is slidably arranged along the axial direction of the sleeve. A second key is provided on the transmission gear, and a second keyway is provided on the outer circumferential surface of the sleeve. The second key cooperates with the second keyway. The first driving mechanism has an output shaft, and a driving gear is fixed on the output shaft. The driving gear is meshed with the transmission gear to realize the transmission connection between the first driving mechanism and the support ring.

[0014] Furthermore, a threaded hole is provided on the side wall of the sleeve, and the sliding block is a bolt installed in the threaded hole, and one end of the bolt extends into the spiral track groove.

This method of rotating and moving toward the aluminum foil roll can make the inner wall of the roll drum of the aluminum foil roll approach and support each other with the support petal in a spiral movement manner, and finally realize the clamping and centering of the aluminum foil roll. Compared with the method of directly moving toward the aluminum foil roll and supporting the aluminum foil roll in the prior art, this method can reduce the friction between the support petal and the inner wall of the roll drum, reduce wear, and thus ensure the centering effect.

[0017] Furthermore, by elastically floating the support flaps on the end face of the support ring, each support flap takes turns to support the reel of the aluminum foil roll, and takes turns to move toward the inside of the reel along with the support shaft. Compared with the method of directly forcing the inside of the reel in the prior art, this method of alternatingly supporting the aluminum foil roll and moving toward the inside of the reel reduces the friction between the support flaps and the inner wall of the reel, thereby reducing the wear on the surface of the support flaps and the inner wall of the reel, ensuring the centering effect of the aluminum foil roll, and will not affect the subsequent operation of the aluminum foil slitting machine.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] An embodiment of a slitting machine cone head of the present invention is as follows Figures 2 to 9 As shown, the slitter cone head 100 is used in the unwinding mechanism of the aluminum foil slitter. When in use, the slitter cone head 100 is respectively installed on the two side boxes of the unwinding mechanism. The boxes on both sides move relative to each other, so that the slitter cone heads 100 on both sides clamp the aluminum foil roll 200 located between the two slitter cone heads 100 (only one side of the slitter cone head 100 is shown in the figure). It should be noted here that the aluminum foil roll 200 includes a reel 202 and an aluminum foil 201 wound on the reel 202. The slitter cone head 100 in the present invention includes a support shaft 101, a support ring 102 and a plurality of support petals 104. The support shaft 101 is used to be rotatably installed on the box of the aluminum foil slitter, and the support ring 102 is rotatably sleeved on the support shaft 101. The support shaft 101 is provided with a first driving mechanism (not shown in the figure), and the first driving mechanism is connected to the support ring 102 in a transmission manner to drive the support ring 102 to rotate relative to the support shaft 101, and the support ring 102 can move along the axial direction of the support shaft 101 when rotating relative to the support shaft 101. The plurality of support petals 104 are evenly distributed along the circumference of the support shaft 101, and the outer periphery of each support petal 104 is provided with a conical inclined surface for matching with the inner wall of the reel 202 of the aluminum foil roll 200. In this embodiment, two adjacent support petals 104 fit each other, so that the plurality of support petals 104 can just form a conical ring structure.

[0031] In the present invention, each support petal 104 is connected to the support ring 102 respectively. When the aluminum foil roll 200 in the middle needs to be clamped, the support shaft 101 located on both sides of the aluminum foil roll 200 gradually moves toward the aluminum foil roll 200 in the middle. When the support shaft 101 moves toward the aluminum foil roll 200, it drives the support ring 102 and the support petal 104 thereon to move toward the aluminum foil roll 200 in the middle. After the support shaft 101 moves a set distance toward the aluminum foil roll 200, the first drive mechanism is started to drive the support ring 102 to rotate relative to the support shaft 101, and the support shaft 101 does not rotate at this time. When the support ring 102 rotates relative to the support shaft 101, it can drive each support petal 104 to rotate synchronously along the circumference of the support shaft 101 and move along the axial direction of the support shaft 101. In order to realize the axial movement of the support ring 102 along the support shaft 101 when it rotates, in this embodiment, a spiral track groove 1011 extending along the circumferential direction of the support shaft 101 is opened on the outer peripheral surface of the support shaft 101, and a sleeve coaxial with the support ring 102 is provided on the side of the support ring 102 away from the support petal 104, and a slider 107 is connected to the side wall of the sleeve, and the slider 107 is located in the spiral track groove 1011. When the first driving mechanism drives the support ring 102 to rotate, the slider 107 slides along the extension direction of the spiral track groove 1011, thereby driving the support ring 102 to move axially along the support shaft 101, so that each support petal 104 is respectively supported on one end of the reel 202 of the aluminum foil roll 200, thereby realizing that the slitting machine cone heads 100 on both sides clamp the aluminum foil roll 200 in the middle and realize the centering of the aluminum foil roll 200. When the slitting machine cone heads 100 on both sides clamp the aluminum foil roll 200, the support shaft 101 rotates and drives the support ring 102 and the support petal 104 to rotate synchronously, thereby driving the middle aluminum foil roll 200 to rotate, thereby realizing the unwinding process of the aluminum foil 201 on the roll 202.

[0032] In this embodiment, each support petal 104 is elastically and floatingly connected to the support ring 102. Specifically, a mounting groove is provided on one end surface of the support ring 102, and one end of the support petal 104 is slidably arranged in the mounting groove along the axial direction of the support ring 102. An elastic member is connected between each support petal 104 and the support ring 102, and the support petal 104 is elastically and floatingly connected to the support ring 102 through the elastic member. In this embodiment, in order to achieve the anti-rotation fit between the support petal 104 and the support ring 102, a first key groove 1041 is provided on the outer circumference of the support petal 104, and a first key is provided in the mounting groove of the support ring 102. The first key and the first key groove 1041 are guided to achieve the anti-rotation fit between the support petal 104 and the support ring 102, and at the same time, the support petal 104 is guided to slide along the extension direction of the first key groove 1041.

[0033] By elastically floating the support petals 104 on the end surface of the support ring 102, when the support petals 104 and the aluminum foil roll 200 begin to contact, the support petals 104 that first press against the inner wall of the roll 202 are pressed against by the roll 202, and shrink toward the support ring 102 and squeeze the elastic member, and the other support petals 104 that are not in contact with the inner wall of the roll 202 will move toward the inside of the roll 202 as the support ring 102 moves. At the same time, as the support ring 102 drives all the support petals 104 to rotate along the circumferential direction of the support shaft 101, the support petals 104 that were originally not in contact with the inner wall of the roll 202 will switch to contact with the inner wall of the roll 202, and the support petals 104 that were originally in contact with the inner wall of the roll 202 will switch to not press against the inner wall of the roll 202 due to the rotation of the support ring 102, and under the action of the elastic member, this part of the support petals 104 will be driven to move toward the inside of the roll 202. Since the support petals 104 that are not supported against the inner wall of the roll 202 extend into the interior of the roll 202 as the support ring 102 moves, as the surrounding support petals 104 switch in turn, each support petal 104 takes turns supporting the roll 202 of the aluminum foil roll 200, and takes turns moving toward the interior of the roll 202 along with the support shaft 101. Compared with the method of directly forcibly squeezing toward the interior of the roll 202 in the prior art, this method of alternately supporting the aluminum foil roll 200 and alternately moving toward the interior of the roll 202 reduces the friction between the support petals 104 and the inner wall of the roll 202, thereby reducing the wear on the surface of the support petals 104 and the inner wall of the roll 202, ensuring the centering effect of the aluminum foil roll 200, and will not affect the subsequent operation of the aluminum foil slitting machine.

[0034] In this embodiment, one end of each support petal 104 located in the installation slot is connected to a guide post 105, a guide hole is provided in the installation slot, and the guide post 105 is inserted into the guide hole. The elastic member is a coil spring 106, each coil spring 106 is respectively sleeved on the guide post 105, and the coil spring 106 is located in the guide hole.

[0035] In this embodiment, the end of the support shaft 101 facing the reel 202 is set as the first end, and the end away from the reel 202 is set as the second end, and the pitch of the spiral track groove 1011 gradually decreases from the second end to the first end of the support shaft 101. After such a setting, the closer the support ring 102 is to the aluminum foil roll 200, the slower it moves along the axial direction of the support shaft 101, ensuring that the support petal 104 and the reel 202 can move slowly after being supported.

[0036] Regarding the transmission structure between the first drive mechanism and the support ring 102, in this embodiment, the sleeve is provided with a transmission gear 103, and the transmission gear 103 is slidably arranged along the axial direction of the sleeve. Specifically, the transmission gear 103 is provided with a second key, and the outer peripheral surface of the sleeve is provided with a second keyway 1021, and the second key cooperates with the second keyway 1021, thereby realizing the anti-rotation cooperation between the transmission gear 103 and the support ring 102, and realizing the axial sliding of the transmission gear 103 along the sleeve, so that when the support ring 102 moves along the axial direction of the support shaft 101, the transmission gear 103 can always be connected to the first drive mechanism. The first drive mechanism includes a first drive motor and a reducer, and the first drive mechanism has an output shaft, and a drive gear is fixed on the output shaft, and the drive gear is meshed with the transmission gear 103 to realize the transmission connection between the first drive mechanism and the support ring 102.

[0037] In this embodiment, a threaded hole is provided on the side wall of the sleeve, and the slider 107 is a bolt installed in the threaded hole, and one end of the bolt extends into the spiral track groove 1011. The inner side surface of each support petal 104 is an arc-shaped surface, and a roller 1042 is rotatably provided on the inner side surface of each support petal 104. The roller 1042 rolls with the outer peripheral surface of the support shaft 101 to reduce the friction resistance of the support petal 104 when it rotates relative to the support shaft 101.

[0038] The slitting machine cone head 100 of the present invention is installed on the two side boxes of the unwinding mechanism of the aluminum foil slitting machine when in use. When working, the aluminum foil roll 200 is first lifted between the two slitting machine cone heads 100 by the overhead crane, and then the two side boxes are driven to move toward the aluminum foil roll 200 in the middle, and the slitting machine cone heads 100 on both sides gradually approach the aluminum foil roll 200. When the slitting machine cone head 100 moves to a part of the support flap 104 and first presses against the inner wall of the roll drum 202 of the aluminum foil roll 200, as shown in FIG. Figure 7In the state shown, the boxes on both sides stop moving, and then the first driving mechanism is started, driving the support ring 102 to rotate relative to the support shaft 101. At the same time, under the cooperation of the slider 107 and the spiral track groove 1011, the support ring 102 moves toward the aluminum foil roll 200, and then drives the support petals 104 on both sides to support the aluminum foil roll 200 toward the middle, so as to clamp the aluminum foil roll 200 and realize the centering of the aluminum foil roll 200. In the process of the support petals 104 clamping the aluminum foil roll 200, the support petals 104 that first press against the inner wall of the reel 202 are pressed by the reel 202, and shrink toward the support ring 102 and squeeze the elastic member, and the other support petals 104 that are not in contact with the inner wall of the reel 202 will move toward the inside of the reel 202 as the support ring 102 moves. At the same time, as the support ring 102 drives all the support petals 104 to rotate circumferentially along the support shaft 101, the support petals 104 that were originally not supported against the inner wall of the reel 202 will switch to contact with the inner wall of the reel 202, and the support petals 104 that were originally supported against the inner wall of the reel 202 will switch to not supporting the inner wall of the reel 202 due to the rotation of the support ring 102, and under the action of the elastic member, this part of the support petals 104 will be driven to move toward the inside of the reel 202. Since the support petals 104 that are not supported against the inner wall of the reel 202 extend into the interior of the reel 202 as the support ring 102 moves, as the surrounding support petals 104 switch in turn, each support petal 104 takes turns supporting the reel 202 of the aluminum foil roll 200, and takes turns moving toward the interior of the reel 202 along with the support shaft 101, thereby achieving the goal of the support petals 104 on both sides clamping the aluminum foil roll 200 in the middle and centering the aluminum foil roll 200.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
