[0024] like Figure 1 and Figure 2As shown, the present application provides an embodiment of a winding mechanism for forklift up and down material taking, which is applied to the winding of film material slitting machine. The winding mechanism for forklift up and down material taking includes a fixed bracket and a winding assembly 200. The fixed bracket has two parallel side panels 100 on the left and right. The bottom ends of the two side panels 100 are separated and fixedly connected by a bottom plate. The winding assembly 200 includes a plurality of translation guide rails 210 fixed on the side panels 100. The translation guide rails 210 on the two side panels 100 are symmetrically arranged. A translation slider 220 is provided on the translation guide rail 210, and a contraction guide rail 230 and a contraction motor 240 are provided on each side of the translation slider 220. A contraction slider 290 is provided on the contraction guide rail 230, and the contraction motor 240 is connected to the contraction slider 290 to drive the contraction slider 290 to move left and right. A winding head 250 is fixed on each contraction slider 290, and a rotating motor 260 is also provided on one side of the contraction slider 290, and the rotating motor 260 is connected to the contraction slider 290 on the side. 0, the two retracting sliders 290 move relative to each other so that the two retracting heads 250 clamp the film material roll 1 for rewinding, and the two retracting sliders 290 move oppositely so that the two retracting heads 250 release the film material roll 1 for unloading, that is, when the two retracting heads 250 move along the retracting guide rails 230 toward the center position of the two side plates 100, the two retracting heads 250 clamp the fixed film material roll 1, and the two retracting heads 250 move along the retracting guide rails 230 away from the two side plates 100. When the material roll is moved to the center position, the two winding machine heads 250 release the material roll 1, so that the forklift forks the material roll 1 from under the material roll 1 for transportation; the synchronization rod 270 is connected between the translation sliders 220 on both sides, and the translation motor 280 is connected to the synchronization rod 270, so that the translation sliders 220 on both sides can be translated synchronously, with the feeding direction of the material roll as the front and the winding direction as the rear, the translation slider 220 translates backward close to the outside of the fixed bracket to facilitate unloading. After unloading is completed, the translation slider 220 translates forward and returns to the working position.

[0025] like Figure 2 As shown, each translation slider 220 is connected to two translation rails 210, which are arranged horizontally and vertically in parallel, and each contraction slider 290 is connected to two contraction rails 230, which are arranged horizontally and in parallel in the transverse direction, thereby ensuring smooth translation and contraction processes. In particular, the translation rails 210 and the contraction rails 230 are in a vertical relationship.

[0026] The rotating head can be extended and retracted to clamp the material shaft of the rotating head to ensure the normal winding, or the rotating head can be extended and retracted to loosen the material shaft of the rotating head to ensure the normal removal of the coil; the fixed axis of the winding can be moved by setting the translation guide rail 210 and the translation slider 220. When winding, the translation slider 220 moves to the set position so that the rotating head moves to the working position to ensure the normal winding of the film material; when unloading, the translation slider 220 moves to another set position, and the rotating head drives the material shaft of the wound film material to translate to the rear side of the fixed bracket, that is, close to the side of the forklift, so that ordinary lifting forklifts can complete the material collection and unloading from bottom to top. The translation forms a dislocation to avoid spatial interference. Ordinary lifting forklifts can lift the material roll 1 up and down for unloading, and there is no need to use a special unloading forklift. At the same time, the layout of the slitting machine is made more compact.

[0027] Only one side of the rotating head is connected to the rotating motor 260, and the rotating head on the opposite side rotates accordingly through the transmission of the material shaft, ensuring the synchronization of the rotation of the two rotating heads, thereby ensuring the stability of the winding process, avoiding deviation or wrinkling during the winding process, and ensuring the winding quality. In addition, a pressure roller is also provided in the winding structure. During the winding process, the pressure roller is always pressed on the winding film to ensure the compactness of the film winding.

[0028] like Figure 2 As shown, in one embodiment, translation gears 2701 are respectively provided at both ends of the synchronization rod 270, and a translation rack 500 is fixed on the side plate 100 corresponding to the translation gear 2701. The translation gear 2701 on the same side meshes with the translation rack 500, and the translation motor 280 is fixed on the translation slider 220 on one side. A pair of synchronous wheels are provided on the rotation axis of the translation motor 280 and the synchronization rod 270, and the synchronous belt connects the synchronous wheels. The synchronization rod 270 and the translation motor 280 rotate synchronously, so that the translation slider 220 translates along the translation rack 500. The translation motor 280 is fixed on the translation slider 220, and the connection between the translation motor 280 and the synchronization rod 270 is realized by the synchronous wheel and the synchronous belt, which drives the rotation of the synchronization rod 270. The rotation of the synchronization rod 270 causes the step roller to roll on the synchronous rack, thereby promoting the translation of the translation slider 220. Changing the rotation direction of the translation motor 280 changes the direction of translation. The translational structural design of the present application is ingenious and simple, and the movement of the translation sliders 220 on both sides is always kept synchronous, which facilitates the precise conversion of the unloading and winding work positions and ensures the stability of the winding quality.

[0029] In one embodiment, there are two retracting guide rails 230 on each translation slider 220, and the parallel retracting guide rails 230 are provided with a screw rod, and a screw rod nut is passed through the screw rod, and the screw rod nut is fixed on the retracting slider 290. The screw rod is connected to the retracting motor 240. A pair of synchronous wheels are provided at one end of the screw rod and the rotating end of the retracting motor 240, and a synchronous belt is connected to the synchronous wheels. The retracting motor 240 rotates synchronously with the screw rod, so that the retracting slider 290 moves left and right on the retracting guide rail 230. The screw rod is driven, with low friction, low noise and low energy consumption.

[0030] In one embodiment, a sprocket is connected to the outer side of the winding head 250 , and the rotary motor 260 is chain-connected to the sprocket to drive the winding head 250 to rotate.

[0031] In one embodiment, first limiting columns are provided at both ends of the translation guide rail 210 on the side plate 100 , and the first limiting columns are used to prevent the translation slider 220 from sliding off the translation guide rail 210 .

[0032] In one embodiment, a second limiting column is disposed at the top of the retractable guide rail 230 , and the second limiting column is used to prevent the retractable slider 290 from sliding off the retractable guide rail 230 .

[0033] In one embodiment, the winding assembly 200 is divided into multiple groups and arranged vertically on a fixed bracket. Generally, the number of winding assemblies 200 can be confirmed according to actual production requirements. Figure 1 As shown, the winding assembly 200 is generally divided into two groups. After winding is completed, when taking the upper layer of film material, the winding assembly 200 of the lower layer drives the coiled material to move forward to avoid it, and the winding assembly 200 of the upper layer drives the coiled material to move backward and slide out, and the forklift grabs the barrel from bottom to top to take the material; when taking the lower layer of film material, the winding assembly 200 of the upper layer does not move, and the winding assembly 200 of the lower layer moves backward and slides out, and the forklift grabs the barrel from bottom to top to take the material. This unloading method can be adapted to various types of forklifts, and there is no need to make a dedicated side-loading forklift. In other embodiments, the winding assembly 200 can be three or more groups, and the material taking principle is similar, all of which are staggered and translated to avoid spatial interference, so that the forklift grabs the barrel from bottom to top to take the material.

[0034] In one embodiment, a drag chain 300 is provided on the translation slider 220 of the winding assembly 200, and the cables of the winding assembly 200 are gathered in the drag chain 300 and connected to the electric box. The drag chain 300 gathers the cables connected to the winding assembly 200 to prevent the cables from becoming scattered due to translation, thereby protecting the safety of the cables during translation. The drag chain 300 can protect the cables from stably following the translation slider 220, thereby preventing the obstruction caused by the cables falling during translation.

[0035] A supporting foot is provided at the bottom end of the fixed bracket, and the height of the supporting foot is adjustable to facilitate the horizontal placement of the device and ensure the normal high-precision winding.

[0036] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0037] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
