Description

Technical Field

[0001] This invention relates to the field of film transport equipment technology, specifically a film production material transport equipment. Background Technology

[0002] A thin film is a thin, flexible, transparent sheet made of plastics, adhesives, rubber, or other materials. Scientifically, a thin film is a two-dimensional material formed by the deposition of atoms, molecules, or ions onto the surface of a substrate. Thin films are widely used in industries such as electronics, machinery, and printing. After the heating, blowing, and cooling processes in production, thin films are often packaged in rolls.

[0003] During film processing, the film transfer process needs to be further processed. Currently, most film rolls are directly stacked on the transport vehicle during film transfer. Due to uneven road surfaces, the film rolls may vibrate during the movement of the transport vehicle, causing them to shake and touch each other, which can easily damage the film surface. Summary of the Invention

The guide pulling part is disposed on the lower side of the bearing seat and is connected to the lower end of the inner switching rod assembly. When the inner switching rod assembly rotates around the axis of the bearing rotating shaft, the guide pulling part can push the inner switching rod assembly to move axially inside the bearing cylinder. A bearing base is disposed on the outer wall of the bearing cylinder near the rotating seat, and the bearing base is used to support the bottom of the film roll portion.

[0011] In one alternative embodiment: the support base includes a fixed support ring and a movable support ring, the fixed support ring is fixed on the support cylinder and the movable support ring is slidably disposed on the support cylinder, the movable support ring is used to support the bottom of the film roll portion fitted on the support cylinder and the movable support ring and the fixed support ring are connected by a support spring portion.

[0012] In one alternative embodiment: the end of the bearing shaft is provided with a gear, and the switching drive component includes a moving rod, a switching cylinder, and at least one vertical rod. The moving rod is slidably disposed on the side of the loading frame away from the roll sleeve mechanism, and the end of the moving rod passes through a clearance hole opened on the loading frame and extends to the side of the loading frame near the roll sleeve mechanism. The vertical rod is disposed at the end of the moving rod and is provided with multiple rack segments, which respectively mesh with the gears on multiple bearing shafts.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this invention, multiple film rolls are mounted on the roll mounting mechanism at an upward tilt.

[0018] 3. The present invention has a simple structure, and the film roll part is easy to install and disassemble. After being fitted onto the roll fitting mechanism, the film roll part is automatically clamped from both ends, ensuring the stability of the film roll part during transportation and effectively preventing the film on the film roll part from being damaged, which facilitates material transportation.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0028] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0029] In one embodiment, such as Figures 1-5As shown, a film production material handling equipment includes a material handling base 100, a loading frame 200, and multiple roll mounting mechanisms 500 for placing film rolls 700. The loading frame 200 is located at the upper end of the material handling base 100, and multiple casters 110 are installed at the lower end of the material handling base 100. Multiple equally spaced bearing shafts 400 are provided on one end face of the loading frame 200, and each bearing shaft 400 is rotatably connected to the end face of the loading frame 200 via multiple bearing seats 420. A switching drive component 600 is also provided on the material handling base 100. Furthermore, the switching drive component 600 is connected to the ends of multiple bearing shafts 400, and the switching drive component 600 is used to drive the multiple bearing shafts 400 to rotate synchronously; multiple roll mounting mechanisms 500 are divided into multiple groups, and multiple groups of roll mounting mechanisms 500 are respectively installed on multiple bearing shafts 400. The roll mounting mechanism 500 includes a bearing cylinder 510, a rotating seat 520, a bearing base 530, an inner switching rod assembly 540, an upper pressing component 550, and a guide pulling part. One end of the rotating seat 520 is fixed on the bearing shaft 400 and connected to one of the bearing seats 400. Correspondingly, the lower end of the bearing cylinder 510 is fixed on the rotating seat 520, and the film roll portion 700 can be sleeved on the bearing cylinder 510 from the top end. The inner switching rod assembly 540 is slidably disposed inside the bearing cylinder 510, and the lower end of the inner switching rod assembly 540 extends to the bottom of the bearing cylinder 510. The upper pressing member 550 is disposed on the inner wall of the top end of the bearing cylinder 510, and the top end of the inner switching rod assembly 540 is connected to the upper pressing member 550. When the inner switching rod assembly 540 moves axially inside the bearing cylinder 510, the upper pressing member 550 can support... The film roll section 700 is opened or closed inside the support cylinder 510, and the upper pressing component 550 is opened and pressed on the top end of the film roll section 700. The guide pulling part is provided on the lower side of the support seat 420 and is connected to the lower end of the inner switching rod assembly 540. When the inner switching rod assembly 540 rotates around the axis of the support rotating shaft 400, the guide pulling part can push the inner switching rod assembly 540 to move axially inside the support cylinder 510. The support cylinder 510 is provided with a support base 530 near the rotating seat 520 on its outer wall, and the support base 530 is used to support the bottom of the film roll section 700.

[0030] In this embodiment of the invention, initially, multiple carrier cylinders 510 are tilted upwards. When installing the film roll portion 700, the switching drive component 600 operates and drives multiple carrier rotating shafts 400 to rotate synchronously. The carrier rotating shafts 400 drive multiple roll mounting mechanisms 500 to rotate, and the roll mounting mechanisms 500 rotate from tilted upwards to a horizontal state. When the carrier cylinder 510 rotates to the horizontal state, the inner switching rod assembly 540 rotates with the carrier cylinder 510, and under the pull of the guide pull part, the bottom of the inner switching rod assembly 540 moves downwards along the axis inside the carrier cylinder 510. The upper pressing component 550 retracts into the carrier cylinder 510 under the pull of the inner switching rod assembly 540. Thus, when installing the film roll portion 700, the film roll portion 700 can be placed horizontally and pushed towards the carrier cylinder 510, thereby realizing the installation of the film roll portion 700. The film roll section 700 is quickly fitted onto the carrier cylinder 510. After the film roll section 700 is fitted onto each carrier cylinder 510, the switching drive component 600 starts working and multiple carrier rotating shafts 400 start to rotate synchronously in opposite directions. As a result, multiple roll fitting mechanisms 500 and film roll sections 700 rotate upward and to an inclined upward state. The bottom of the film roll section 700 is supported by the carrier base 530. When the inner switching rod assembly 540 rotates upward with the carrier cylinder 510, the guide pull part can push the inner switching rod assembly 540 to move upward along the axis of the carrier cylinder 510. The upwardly moving inner switching rod assembly 540 acts on the upper pressure component 550 and causes the upper pressure component 550 to open. The opened upper pressure component 550 presses on the top end of the film roll section 700, thereby realizing automatic clamping of the film roll section 700 and avoiding large vibrations of the film roll section 700 when the entire device moves.

[0031] In one embodiment, such as Figures 1-5 As shown, the guiding pull part includes an arc-shaped guide rod 560 and a push-pull movable seat 570. One end of the arc-shaped guide rod 560 is fixedly connected to the bottom of the bearing seat 420, and the other end of the arc-shaped guide rod 560 extends to the lower side of the bearing cylinder 510. The push-pull movable seat 570 is slidably sleeved on the arc-shaped guide rod 560 and is hinged to the bottom of the inner switching rod assembly 540. In this embodiment of the invention, when the bearing cylinder 510 and the inner switching rod assembly 540 rotate around the bearing pivot... When the 400 axis rotates, the inner switching rod assembly 540 drives the push-pull movable seat 570 to move on the arc-shaped guide rod 560. Since the center point of the arc-shaped guide rod 560 is not on the axis of the bearing rotating shaft 400, the distance between the connection point of the push-pull movable seat 570 and the inner switching rod assembly 540 and the axis of the bearing rotating shaft 400 will change. As a result, the push-pull movable seat 570 can pull and push the inner switching rod assembly 540 to move axially inside the bearing cylinder 510.

[0032] In one embodiment, such as Figures 2-6As shown, the top sidewall of the bearing cylinder 510 has multiple clearance notches 511, and the pressing component 550 includes multiple pressing rods 551 corresponding to the multiple clearance notches 511. A connecting shaft 553 is provided on the side of each pressing rod 551, and the connecting shaft 553 is rotatably connected to the inner wall of the corresponding pressing rod 551. A tail rod frame 552 is provided at the end of each pressing rod 551 facing the interior of the bearing cylinder 510. The inner switching rod assembly 540 includes a switching rod 541 and multiple branch rods 542. The switching rod 541 is axially slidably disposed inside the bearing cylinder 510, and its bottom end is hinged to the push-pull movable seat 570. Multiple branch rods 542 are disposed on the top of the switching rod 541, and each branch rod 542 corresponds one-to-one with a tail rod frame 552. An actuating roller 543 is provided on the top of each branch rod 542, and the actuating roller 543 passes through the corresponding tail rod frame 552. In this embodiment of the invention, when the switching rod 541... When the push-pull movable seat 570 moves axially inside the bearing cylinder 510, the branch rod 542 acts on the tail rod frame 552 and pushes or pulls the tail rod frame 552 upward or downward. Therefore, the clamping rod 551 rotates around the connecting shaft 553. The clamping rod 551 can rotate to a state parallel to the inside of the bearing cylinder 510 and to a state perpendicular to the axis of the bearing cylinder 510. When the clamping rod 551 is retracted inside the bearing cylinder 510, it facilitates the film roll section 7. The 00 insert is mounted on the support cylinder 510. When the clamping rod 551 is unfolded and kept perpendicular to the axis of the support cylinder 510, the clamping rod 551 presses against the top end of the film roll 700 to ensure the stability of the film roll 700. The end face of the clamping rod 551 pressing against the top of the film roll 700 has an air bladder 554. The air bladder 554 can prevent the film wound on the film roll 700 from being directly released from the clamping rod 551, thus avoiding tearing the film.

[0033] In one embodiment, such as Figures 3-6 As shown, the support base 530 includes a support fixing ring 531 and a support movable ring 532. The support fixing ring 531 is fixed on the support cylinder 510, and the support movable ring 532 is slidably disposed on the support cylinder 510. The support movable ring 532 is used to support the bottom of the film roll portion 700 fitted on the support cylinder 510, and the support movable ring 532 and the support fixing ring 531 are connected by a support spring portion 533. In this embodiment of the invention, since the support movable ring 532 can slide on the support cylinder 510 under the elastic damping action of the support spring portion 533, the film roll portion 700 can be elastically damped and pressed on the support cylinder 510, and the support spring portion 533 can play a certain buffering role.

[0034] In one embodiment, such as Figures 1-7As shown, the end of the bearing shaft 400 is provided with a gear part 410, and the switching drive component 600 includes a movable rod 610, a switching cylinder part 620, and at least one vertical rod part 630. The movable rod 610 is slidably disposed on the side of the loading frame 200 away from the roll sleeve mechanism 500, and the end of the movable rod 610 passes through the clearance hole 230 opened on the loading frame 200 and extends to the side of the loading frame 200 near the roll sleeve mechanism 500. The vertical rod part 630 is disposed at the end of the movable rod 610, and the vertical rod part 630 is provided with a gear part 410. Multiple rack segments 640 are respectively engaged with gears 410 on multiple bearing shafts 400; the switching cylinder 620 is provided on the material conveying base 100 and the top end of the switching cylinder 620 is connected to the moving rod 610; in this embodiment of the invention, the switching cylinder 620 drives the moving rod 610 to move up or down by telescoping, the moving rod 610 drives the vertical rod 630 to move vertically, and the vertically moving vertical rod 630 causes the bearing shaft 400 to rotate through the engagement of the rack segments 640 and the gears 410.

[0035] In one embodiment, such as Figure 1 , Figure 2 and Figure 7 As shown, the top of the material conveying base 100 is provided with a top guard plate 210, and the back of the loading frame 200 away from the roll sleeve mechanism 500 is provided with a handle 220, and both sides of the loading frame 200 are provided with side guard plates 300; in this embodiment of the invention, the top guard plate 210 and the side guard plates 300 can surround multiple roll sleeve mechanisms 500 from the top and sides, which can play a protective role.

[0036] In one embodiment, such as Figure 1 , Figure 2 and Figure 7As shown, the bottom of the side guard plate 300 is slidably connected to the side of the material conveying base 100. The two side guard plates 300 are connected to each other at least one upper connecting rod 310 away from the roll mounting mechanism 500. The movable rod frame 610 is provided with a fixed connecting rod 650 with its end fixedly connected, and the fixed connecting rod 650 is provided with at least one movable connecting rod 660. One end of the movable connecting rod 660 is rotatably connected to the fixed connecting rod 650 and the other end is rotatably connected to the upper connecting rod 310. In this embodiment of the invention, before installing the film roll 700, the switching cylinder 620 moves upward and drives the movable rod frame 610 to move upward. The upwardly moving movable rod frame 610 acts on the gear 410 through the vertical rod 630 and the rack section 640, causing the gear 410 to rotate. The moving rod 610 rotates the roll-on sleeve mechanism 500 to a horizontal position. At the same time, the moving rod 610 pushes the upper connecting rod 310 through the moving rod 610 and the movable connecting rod 660, causing the upper connecting rod 310 and the side guard plate 300 to move away from the roll-on sleeve mechanism 500 along the side of the material conveying base 100. The side guard plate 300 is no longer on the side of the roll-on sleeve mechanism 500, which facilitates the sleeve of the film roll 700. After the film roll 700 is sleeved, the moving rod 610 moves downward under the action of the switching cylinder 620. Therefore, the roll-on sleeve mechanism 500 rotates to an upward tilted position and the side guard plate 300 moves back to the front of the loading frame 200, which facilitates the protection of the film roll 700 on the roll-on sleeve mechanism 500.

[0037] The above embodiment proposes a film production material handling equipment. When installing the film roll section 700, the switching drive component 600 operates and drives multiple bearing shafts 400 to rotate synchronously. The bearing shafts 400 drive multiple roll-mounting mechanisms 500 to rotate, and the roll-mounting mechanisms 500 rotate from an inclined upward position to a horizontal position. When the bearing cylinder 510 rotates to the horizontal position, the inner switching rod assembly 540 rotates with the bearing cylinder 510, and under the pull of the guide pull part, the bottom of the inner switching rod assembly 540 moves downward along the axis inside the bearing cylinder 510. The upper pressing component 550 retracts into the bearing cylinder 510 under the pull of the inner switching rod assembly 540. Therefore, when installing the film roll section 700, the film roll section 700 can be placed horizontally and pushed towards the bearing cylinder 510, enabling the film roll section 700 to be quickly mounted. On each of the support cylinders 510, after a film roll portion 700 is fitted onto it, the switching drive component 600 operates and multiple support shafts 400 begin to rotate synchronously in opposite directions. As a result, multiple roll mounting mechanisms 500 and film roll portions 700 rotate upward and to an inclined upward state. The bottom of the film roll portion 700 is supported by the support base 530, and when the inner switching rod assembly 540 rotates upward with the support cylinder 510, the guide pull part can push the inner switching rod assembly 540 to move upward along the axis of the support cylinder 510. The upwardly moving inner switching rod assembly 540 acts on the upper pressure component 550 and causes the upper pressure component 550 to open and press on the top end of the film roll portion 700, thereby achieving automatic clamping of the film roll portion 700 and preventing the film roll portion 700 from vibrating significantly when the entire device moves.

[0038] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
