Description

Technical Field

[0001] The utility model relates to the technical field of film production, and specifically to a core transfer trolley. Background Art

[0002] In the film industry, the film is wound around a core to form the final film product. The core is widely used as an indispensable packaging auxiliary material. However, due to the shape characteristics of the core, it is extremely vulnerable to collision during transportation, loading, unloading, and handling. Damage to the surface of the core will cause defects such as wrinkles and bumps on the film wound around it, affecting the quality of the film product. Therefore, special core transfer equipment is needed to transport the core.

[0003] In the prior art, for example, the utility model patent with the application number CN202320394124.7 discloses a core storage and transfer trolley, which includes a straight plate and a slide rail. The straight plate is installed at the left end of the upper surface of the base, and the included angle between the straight plate and the base is greater than 90°. One end of the slide rail is connected to the straight plate, and the other end is a free end; the distance between adjacent slide rails is greater than the outer diameter of the core; the diameter of the smallest circle that can accommodate the cross-section of the slide rail is less than the inner diameter of the core; anti-collision strips are provided on the upper and lower parts of the area on the straight plate that contacts the slide rail.

[0004] During the use of this transfer trolley, the collision between the core and the vehicle frame can be reduced. However, in actual use, since the core diameter is greater than the slide rail diameter, as the transfer trolley moves, the core will also shake in the up and down direction, causing bumps on the inner wall of the core and even deforming the outside of the core.

[0005] Therefore, it is necessary to propose a core transfer trolley to at least partially solve the problems existing in the prior art. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will clearly and completely describe the technical solutions of the present utility model with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present utility model belong to the scope of protection of the present utility model.

[0032] Embodiment

[0033] The following will further describe the present utility model with reference to the drawings.

[0034] As Figures 1-3 shown, the die transfer cart provided in this embodiment includes:

[0035] A frame, with a plurality of die support frames 2 connected to the side of the frame. The top end of the die support frame 2 is connected with rollers 3, and the bottom end of the die support frame 2 is rotatably connected with an inner support frame 4. The die 1 is sleeved on the die support frame 2, and the inner wall of the die 1 abuts against the rollers 3 and the inner support frame 4.

[0036] The working principle and beneficial effects of the present utility model are as follows:

[0037] When the die transfer cart provided in this embodiment transfers the die 1, the die 1 is sleeved into the free end of the die support frame 2. The top end of the inner wall of the die 1 is supported on the rollers 3 and moves along the rollers 3 until it contacts the side of the frame; then the inner support frame 4 is rotated downward so that the inner support frame 4 abuts against the bottom end of the inner wall of the die 2 to fix it; the frame is pushed to transfer the die 1 to the designated position, and then the inner support frame 4 is rotated in the reverse direction to make it retract again, and the die 1 can be removed from the die support frame 2. Through the above structural design, in the form of a combination of the rollers 3 and the inner support frame 4, the top and bottom of the die 1 are respectively supported and fixed, reducing the vertical shaking of the die 1, keeping the die 1 stable when moving with the frame, and avoiding the deformation of the external structure caused by the collision of the inner wall of the die 1; when the die 1 is installed and disassembled, it rolls along the rollers 3, and the transfer is labor-saving and convenient.

[0038] Among them, the frame includes a bottom plate 11 and side plates 12. A lockable universal wheel 13 is connected to the bottom of the bottom plate 11, and a handle 14 is connected to the outside of the side plate 12.

[0039] The lockable universal wheel 13 is arranged on the frame bottom plate 11, which is convenient for the movement of the frame and can be locked at any use position. The handle 14 is arranged on the frame side plate 12, which is convenient for the staff to push.

[0040] Among them, a plurality of die support frames 2 are arranged at a preset interval. The die support frames 2 are inclined, and the lower end of the die support frame 2 is connected to the side plate 12.

[0041] By arranging the die support frame 2 to be inclined, after the die 1 is installed on the die support frame 2, its end abuts against the frame side plate 12 under the action of gravity, reducing the shaking of the die 1 during the transfer process and preventing the die 1 from coming out.

[0042] As Figures 2-4 shown, in one embodiment, a transmission groove 21 is provided at the bottom of the die support frame 2, and the transmission groove 21 includes:

[0043] A worm 22, which is rotatably connected to both ends of the transmission groove 21;

[0044] The motor 23 is installed at the end of the die carrier support 2, and the output end of the motor 23 is connected to the worm 22.

[0045] The worm gear 24 is rotatably connected to the side wall of the transmission groove 21. The worm gear 24 is meshed and connected with the worm 22, and the worm gear 24 is connected to the inner support frame 4.

[0046] The inner support frame 4 includes: a sleeve 25, a telescopic rod 26 and a sphere 27. The end of the sleeve 25 is connected to the worm gear 24; one end of the telescopic rod 26 is slidably arranged in the sleeve 25, and a spring 28 is connected between the end of the telescopic rod 26 and the inner wall of the sleeve 25; the sphere 27 is connected to the other end of the telescopic rod 26.

[0047] A rubber pad 29 is wrapped around the sphere 27.

[0048] The working principle and beneficial effects of the above technical solution are as follows:

[0049] The expansion and retraction of the inner support frame 4 are adjusted by the motor 23. When the inner support frame 4 needs to be expanded, the motor 23 is started to drive the worm 22 to rotate forward. The worm 22 is in meshing transmission with the worm gear 24, driving the worm gear 24 to rotate clockwise. The worm gear 24 drives the inner support frame 4 to expand downward; the telescopic rod 26 of the inner support frame 4 contacts the bottom of the inner wall of the die 1. After being pressed by the pipe wall, the telescopic rod 26 contracts into the sleeve 25, and at the same time stores energy in the spring 28; the sphere 27 at the bottom of the telescopic rod 26 abuts against the inner wall of the die 1 and forms a preset angle with the die 1. When the inner support frame 4 needs to be retracted, the motor 23 is started to drive the worm 22 to rotate reversely, driving the inner support frame 4 to rotate upward and separate from the inner wall of the die 1, and retracting into the transmission groove 21, so that the die 1 can be taken out from the die carrier support 2.

[0050] Through the above structural design, the elastically arranged inner support frame 4 can adjust the total length of the inner support frame 4 according to the different inner diameters of the die 1 when fixing the die 1, so that it can abut against the die 1 and cooperate with the roller 3 to achieve the function of fixing the die 1, and can adapt to the transfer of different specifications of the die 1; when the inner support frame 4 is expanded, the die 1 rotates towards the side plate 12. A rubber pad 29 is wrapped around the sphere 27, and there is friction between the rubber pad 29 and the die 1. Under the action of the friction, the die 1 is assisted to closely adhere to the side plate 12, and the installation stability is higher.

[0051] Among them, as Figures 2-5 shown, a limiting plate 30 is connected to the side wall of the transmission groove 21. A through hole 31 is provided at the center of the limiting plate 30, and the worm 22 passes through the through hole 31; an arc-shaped limiting groove 32 is provided at the bottom of the limiting plate 30, and the top end of the telescopic rod 26 contacts the arc-shaped limiting groove 32.

[0052] The through hole 31 allows the worm 22 to pass through; when the inner support frame 4 is retracted into the transmission groove 21, the inner support frame 4 is limited by the arc-shaped limiting groove 32 to prevent interference between the inner support frame 4 and the worm 22.

[0053] Among them, a buffer plate 15 is connected to the side plate 12, and the end of the tube core 1 contacts the buffer plate 15.

[0054] Through the setting of the buffer plate 15, during the sliding process of the tube core 1 in the direction of the side plate 12 during installation and during the transfer by the cart, the impact on the end of the tube core 1 caused by the shaking and hitting of the side plate 12 is reduced, and damage to the end of the tube core 1 is avoided.

[0055] Among them, the center line of the worm gear 24 is located on the side of the center line of the roller 3 close to the side plate 12.

[0056] Among them, both the rollers 3 and the inner support frames 4 are provided in multiple numbers and are evenly arranged along the length direction of the tube core support frame 2, and the positions of the rollers 3 and the inner support frames 4 correspond one by one.

[0057] Through the above structural design, after the inner support frame 4 rotates, the contact position between the sphere 27 and the tube core 1 can be close to the position of the roller 3, and the top and bottom of the tube core 1 at the adjacent positions are supported, and the fixing effect is better.

[0059] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
