Description

TECHNICAL FIELD

[0001] The application relates to a roll material feeding mechanism. BACKGROUND

[0002] Roll material feeding is a common material loading link in industrial production, mainly referring to accurately installing a rolled raw material to a specified position of a production device, so as to subsequently perform processing operations such as slitting, printing, compounding and bag making.

[0003] In addition, the existing patent with the publication number CN217894602U discloses a heavy roll double-screw automatic feeding and discharging mechanism.

[0004] Firstly, the feeding process of the device needs to drive the lead screw to rotate through the lifting motor, so as to complete the feeding of the roll material. Since the transmission system composed of the left lead screw, the right lead screw and the synchronous shaft is relatively complex, the lead screw is prone to wear and deformation after long-term use, which leads to a decrease in transmission precision and affects the lifting stability of the material loading assembly. At the same time, the speed of the lead screw transmission is relatively slow, which will reduce the overall efficiency of the feeding operation. In order to improve the efficiency of roll material feeding, the present application provides a roll material feeding mechanism facilitating material replacement. CONTENT OF THE INVENTION

[0005] In order to improve the low efficiency of roll material replacement, the application provides a roll material feeding mechanism facilitating material replacement.

[0008] Through the above technical solution, the support assembly provides necessary support and assistance for the roll material replacement process. It can effectively position and fix the roll material, facilitate the replacement operation of the operator, and ensure the efficiency, accuracy and safety of the replacement process. The feeding assembly realizes the feeding operation of the roll material. It can transport the roll material from the initial position to the specified working position, and prepare for the subsequent processing or use. The driving assembly is installed in the middle of the feeding assembly. It is the power source of the feeding assembly. The driving assembly provides appropriate power to drive the feeding assembly to complete various actions, so that the roll material can be smoothly fed.

[0009] Preferably, the supporting assembly comprises a threaded rod rotationally connected with the base, a lifting plate threadedly connected with the threaded rod, one end of the lifting plate movably penetrating a limiting column, the top end of the lifting plate symmetrically fixedly provided with a first support, a first arc-shaped groove being formed in the top of the first support, and a slope being formed in the top of the first support at one side of the first arc-shaped groove.

[0010] By adopting the above technical scheme, the lifting plate is threadedly connected with the threaded rod, and is driven to move linearly along the limiting column under the rotation of the threaded rod. The lifting plate serves as a mounting base of the first support, bears the weight of the first support and the coiled material placed on the first support, and adjusts the height of the coiled material by itself to meet the height requirement during material replacement. The limiting column movably penetrates the lifting plate, limits and guides the movement of the lifting plate, ensures that the lifting plate can only move linearly along the direction of the limiting column under the driving of the threaded rod, prevents the lifting plate from deviating or shaking during movement, and ensures the stability and accuracy of the movement. The first arc-shaped groove is located at the top of the first support, and the arc-shaped design thereof is matched with the outer surface of the winding drum to increase the contact area with the coiled material, better support the coiled material, reduce the risk of rolling or sliding of the coiled material during placement, and ensure the stability of the coiled material placement.

[0011] Preferably, the first support is fixedly provided with a support block at one side, the support block is fixedly provided with a first servo motor at the top, and the output end of the first servo motor is fixedly connected with a poking plate penetrating the first support.

[0012] By adopting the above technical scheme, the first servo motor is installed at the top of the support block and serves as a power source. The first servo motor can accurately control the rotation speed, torque and position of the output, and provides power for the movement of the poking plate. The poking plate is fixedly connected with the output end of the first servo motor and is driven to rotate or swing by the first servo motor. The poking plate serves to push the coiled material during material replacement, assist the coiled material to separate from the current position, and the like, so as to realize a more efficient and accurate material replacement process.

The sliding groove is arranged in the second support to provide a track for sliding of the sliding rod and the limiting rod, limits the movement path of the sliding rod and the limiting rod, ensures that the sliding rod and the limiting rod can slide in a specific direction, and ensures the directionality and stability of the feeding action. The sliding rod is in sliding connection with the sliding groove and can freely slide in the sliding groove. The sliding rod penetrates the rotating disc to drive the rotating disc to move in the direction limited by the sliding groove, is a key component for linear displacement of the feeding assembly, provides a translational motion for position adjustment in the process of feeding the coiled material, and is fixedly penetrated by the sliding rod and can move with the sliding rod. The arc-shaped hole in the rotating disc provides a sliding space for the limiting rod. When the sliding rod drives the rotating disc to move, the rotating disc will rotate due to sliding of the limiting rod in the arc-shaped hole to provide a rotating action for feeding the coiled material. The limiting rod is in sliding connection with the sliding groove and the arc-shaped hole. On one hand, the limiting rod slides in the sliding groove to limit the movement path of the limiting rod. On the other hand, the limiting rod slides in the arc-shaped hole to control rotation of the rotating disc by cooperation with the arc-shaped hole, plays a role of connecting and coordinating linear motion of the sliding rod and rotational motion of the rotating disc, and ensures the coordination and stability of movement of the feeding assembly.

[0015] Preferably, the sliding rod is symmetrically and movably penetrated by a support plate, and a second arc-shaped groove is arranged at the top of the support plate.

[0016] By adopting the technical scheme, the second arc-shaped groove arranged at the top of the support plate can be used for placing the coiled material to provide support and positioning for the coiled material and assist in stable placement of the coiled material in the feeding process. The sliding rod is symmetrically and movably penetrated by the rotating block on one side of the support plate. The rotating block can move on the sliding rod to prepare for subsequent installation of a driving device.

[0019] Preferably, the driving assembly comprises a cylinder fixedly connected with the rotating block, a rotating plate is fixedly arranged at the mounting end of the cylinder, and a fixed block fixedly connected with the base is hingedly arranged on the rotating plate.

[0020] By adopting the technical scheme, the cylinder is fixedly connected with the rotating block, serves as a power output component, provides power for the rotating block through telescopic movement, drives the rotating block to move when the cylinder telescopes, and thus causes the support plate associated with the rotating block to change position correspondingly to realize the action of feeding.

[0021] Preferably, a groove is formed at one end of the top of the base away from the lifting plate, and a limiting groove is formed above the groove.

[0037] The embodiment of the application discloses a roll material feeding mechanism facilitating material replacement.

[0038] Referring to Figure 1 、 Figure 2 、 Figure 6 As shown in the drawings, a roll material feeding mechanism facilitating material replacement comprises a base 1, and a support assembly for roll material replacement is arranged at one end of the top of the base 1, the support assembly comprises a threaded rod 2, the bottom end of the threaded rod 2 is rotationally connected to the side surface of one end of the base 1, the threaded rod 2 is threadedly connected to a threaded hole arranged at one end of a lifting plate 3, a circular hole is arranged at the end of the lifting plate 3 away from the threaded rod 2, a limiting column 4 is movably penetrated into the circular hole, a threaded column 103 is installed at the top of the base 1 and located in the middle of the bottom of the lifting plate 3, a jacking block 104 is threadedly connected to the top end of the threaded column 103, the jacking block 104 abuts against the middle of the bottom of the lifting plate 3, a side plate 105 is fixedly connected to one side of the jacking block 104, first supports 5 are symmetrically fixedly connected to the top end of the lifting plate 3, a first arc-shaped groove 6 is arranged at one side of the top of the first support 5, an arc-shaped protrusion is arranged at one side of the first arc-shaped groove 6, a slope 7 is arranged at the top of the first support 5, one end of the slope 7 is connected to the first arc-shaped groove 6, a support block 8 is fixedly installed at one side of the first support 5 and close to the upper side, the support block 8 is fixedly connected to the mounting seat of a first servo motor 9 at the top, and a poking plate 10 is fixedly connected to the output end of the first servo motor 9 through a circular hole arranged at the side of the first support 5.

[0039] By rotating the threaded rod 2, since the threaded rod 2 is threadedly connected with the lifting plate 3, the lifting plate 3 is guided and limited by the limiting column 4, the lifting plate 3 will make linear lifting movement along the limiting column 4, so as to adjust the height of the first support 5, then the threaded column 103 is installed on the top of the base 1 and in the middle of the bottom of the lifting plate 3, then the side plate 105 on one side of the jacking block 104 at the top of the threaded column is rotated, so that the top end of the jacking block 104 abuts against the middle position of the top of the lifting plate 3, thereby playing a reinforcing role, so that the first support 5 is in a suitable material changing position to adapt to the subsequent installation of the air inflation shaft, when the coiled material is on the slope 7 at the top of the first support 5, the coiled material will roll along the slope 7 into the first arc-shaped groove 6 under the action of its own gravity, the arc-shaped protrusion can prevent the coiled material from rolling or sliding excessively, and ensure that the coiled material is stably placed, when the coiled material is finished, the output end of the first servo motor 9 is started to drive the rotating plate 10 to rotate, the rotating plate 10 is used for pushing the coiled material, and the material changing action of the coiled material is assisted to be completed, so that the subsequent feeding process can be smoothly carried out.

[0040] Referring to Figure 2 Figure 4 As shown in the drawings, the top of the base 1 is provided with a feeding assembly for coiled material feeding near one side of the supporting assembly, the feeding assembly comprises second supports 11 symmetrically and fixedly installed at the top of the base 1, two sliding grooves 12 are formed in the second supports 11 along the inclined direction of the second supports 11, a sliding rod 13 is slidably connected in one of the sliding grooves 12, two rotating discs 14 are fixedly penetrated through the sliding rod 13, a gear slot is formed in the outer peripheral surface of one of the rotating discs 14, arc-shaped holes 1401 are formed in the interiors of the two rotating discs 14, a limiting rod 15 is slidably connected in the arc-shaped holes 1401, the limiting rod 15 is slidably connected with the other sliding groove 12, the sliding rod 13 symmetrically and movably penetrates through the second arc-shaped groove 17 formed in the top of a supporting plate 16, an arc-shaped protruding block is arranged on one side of the supporting plate 16, rotating blocks 18 with flat side surfaces are symmetrically movably penetrated through one side of the supporting plate 16, a fixed plate 22 with a circle formed in the side surface is fixedly installed at the top of the second support 11, one side of the fixed plate 22 is fixedly connected with the mounting seat of a second servo motor 23, the output end of the second servo motor 23 is fixedly connected with the rotating disc 14 penetrating through the circular hole of the fixed plate 22, a gear slot is formed in the outer peripheral surface of the rotating disc 14, and the rotating disc 14 is meshingly connected with a driving wheel 24.

[0041] ​The second servo motor 23 is started by connecting an external power supply to the control device connected to the second servo motor 23, and the output position, speed and acceleration of the motor are precisely controlled by a closed-loop control system (including a servo driver, a servo motor and a feedback device such as an encoder). The output end of the second servo motor 23 drives the driving wheel 24 to rotate. Since the driving wheel 24 is engaged with the tooth groove on the outer periphery of the rotating disc 14, the rotating disc 14 rotates. The arc-shaped hole 1401 in the rotating disc 14 is in sliding connection with the limiting rod 15, and the limiting rod 15 is fixed in the other sliding groove 12. Therefore, when the rotating disc 14 rotates, the limiting rod 15 rotates in the arc-shaped hole 1401 in the rotating disc 14. At the same time, since the sliding rod 13 is fixed through the support plate 16, the sliding rod 13 drives the support plate 16 to rotate synchronously. The second arc-shaped groove 17 at the top of the support plate 16 is used to carry the coiled material. When the support plate 16 is inclined at a certain angle, the coiled material in the second arc-shaped groove 17 will be affected by gravity and roll down to the slope 7 on the top of the first support 5, thereby completing the feeding of the coiled material.

[0042] It should be noted that the first servo motor 9 and the second servo motor 23 are both ASD-B2 series servo motors of Delta. The first servo motor 9 and the second servo motor 23 need to be connected to Delta servo ASD-B2-0721-B servo drivers and be provided with controllers. The electrical signals generated by the servo drivers are transmitted to the controllers through lines. After receiving and analyzing these signals, the controllers generate corresponding control instructions according to the preset program and transmit the instructions to the first servo motor 9 and the second servo motor 23 through lines, so as to accurately control the running state of the first servo motor 9 and the second servo motor 23, such as adjusting the rotating speed, starting and stopping, etc. The first servo motor 9 and the second servo motor 23 and their connecting lines are prior art and mature, so the specific connection relationship will not be described in detail. The existing connection assembly can be installed and used.

[0043] Referring to Figure 1 , Figure 5 As shown in the drawings, the middle part of the feeding assembly is provided with a driving assembly. The driving assembly includes a cylinder 19. One side of the cylinder 19 is fixedly connected with a rotating block 18. The mounting end of the cylinder 19 is fixedly connected with a rotating plate 20 with a circular hole in the side surface. The rotating plate 20 is hingedly connected with a fixed block 21 at the circular hole. The bottom end of the fixed block 21 is fixedly connected with a base 1. A recess 101 is horizontally formed in the top of the base 1 away from one end of the lifting plate 3. A limiting groove 102 with the same width as the size of the coiled material is formed in the top of the base 1 above the recess 101.

[0044] The extension and contraction of the pneumatic driver driving cylinder 19 drives the rotating block 18, the mounting end of the cylinder 19 is fixedly connected with the rotating plate 20, the rotating plate 20 is hinged with the fixed block 21 through a circular hole, and the rotating plate 20 will rotate around the hinge point with the fixed block 21 during the extension and contraction of the cylinder 19, thereby providing flexible support for the cylinder 19 and ensuring smooth extension and contraction of the cylinder 19. The rotating block 18 is movably penetrated by the sliding rod 13, and the movement of the rotating block 18 drives the sliding rod 13 to slide in the sliding groove 12 of the second support 11, and the sliding rod 13 drives the support plate 16 connected thereto to move, thereby adjusting the position of the feeding assembly and completing the feeding of the coiled material. When the cylinder 19 is fully extended, the sliding rod 13 is located at the upper end of the sliding groove 12, and when the cylinder 19 is fully retracted, the sliding rod 13 is located at the lower end of the sliding groove 12. The coiled material to be fed is placed in the limiting groove 102 in advance to prepare for subsequent feeding and improve the efficiency of feeding.

[0045] It should be noted that the cylinder 19 is preferably a multi-stage cylinder and uses the product of Guoying Fluid Technology (Jiangsu) Co., Ltd. A pneumatic driver is arranged for controlling the cylinder 19. The cylinder 19 and the driver are prior art and mature, and thus the specific connection relationship will not be described in detail. The existing connection assembly can be installed for use.

[0046] The implementation principle of the coiled material feeding mechanism facilitating material replacement is as follows: first, the base 1 is moved so that the base 1 can be docked at the feeding end of the discharging device, then the threaded rod 2 is rotated, the threaded rod 2 is threadedly connected with the lifting plate 3, the lifting plate 3 is guided and limited by the limiting column 4, the lifting plate 3 moves linearly along the limiting column 4, thereby adjusting the height of the first support 5 so that the first support 5 is at a suitable material replacement position, and the subsequent installation of the gas inflation shaft (the gas inflation shaft uses the device in Patent No. CN217894602U, and the gas inflation shaft is fixed by being inserted into the pipe of the coiled material) is adapted, the second servo motor 23 drives the driving wheel 24 to rotate, the driving wheel 24 is engaged with the outer peripheral tooth groove of the rotating disc 14 to drive the rotating disc 14 to rotate (it should be noted that the driving wheel 24 needs to be slightly rotated to enhance the engagement with the rotating disc 14 when the driving wheel 24 is engaged with the rotating disc 14), the sliding rod 13 drives the support plate 16 to rotate synchronously, and when the support plate 16 is inclined to 90 degrees, the coiled material in the second arc-shaped groove 17 rolls onto the slope 7 on the top of the first support 5 under the action of gravity, and the preliminary feeding is completed.

[0047] Then the extension and contraction end of the cylinder 19 drives the rotating block 18 to move, the rotating block 18 drives the sliding rod 13 to slide in the sliding groove 12 of the second support 11, the sliding rod 13 drives the support plate 16 to move, the sliding rod 13 is located at the upper end of the sliding groove 12 when the cylinder 19 is fully extended, and the sliding rod 13 is located at the lower end of the sliding groove 12 when the cylinder 19 is fully retracted, thereby completing the final feeding of the coiled material.

[0048] When the winding material unloading ends, the first servo motor 9 drives the rotating plate 10 to rotate, the rotating plate 10 drives one end of the winding drum, the winding drum is extruded by the rotating plate 10, and gradually separates from the first arc-shaped groove 6 along the slope at one end of the first support 5, thereby assisting to complete the separation of the old winding material and recycling the old winding drum through the recycling box, preparing for the feeding of the new winding material.

[0049] The above is only an optional embodiment of the present disclosure and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
