Description

Technical Field

[0001] This utility model relates to a rewinding machine for preventing foil from loosening and retracting. Background Technology

[0002] A winding machine is the receiving part of a roll material processing production line. It mechanically winds materials into rolls and is widely used in paper rolls, cloth rolls, plastic rolls, and metal roll processing production lines. When winding materials, the foil winding machine pulls the foil, and then the winding roller rotates to wind the foil into a bundle. During this process, due to the pulling of the winding roller, the aluminum foil is not easy to loosen or shrink back.

[0003] The existing winding machine does not have a structure to prevent the foil from loosening and shrinking. During the winding process, problems with the foil may occur due to tension issues. If the tension is too high, the foil will be stretched and deformed. If the tension is too low, the foil will loosen and shrink due to the lack of tensile force, resulting in the entire roll of material becoming loose and easily causing winding failure or foil damage. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a winding machine that prevents foil from loosening and retracting.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A winding machine for preventing foil from loosening and retracting includes a winding machine frame, a drive mechanism, a winding roller, a winding drum detachably mounted on the winding roller, and a pressure roller, the pressure roller being located in front of the winding roller. The winding machine also includes a foil tension clamping mechanism located between the winding roller and the pressure roller. The foil tension clamping mechanism includes a horizontal shaft rotatably mounted on the winding machine frame, side rods fixedly mounted at both ends of the horizontal shaft, a foil clamping roller mounted at one end of the two side rods, a tension adjusting roller mounted at the other end of the two side rods, and an elastic traction assembly disposed between the winding machine frame and the side rods.

[0006] Preferably, the elastic traction assembly includes a first hook fixed to the side mounting rod, a second hook fixed to the winding frame, and elastic elements with their two ends respectively hooked to the first hook and the second hook.

[0007] Furthermore, the elastic element is a spring.

[0008] Preferably, the drive mechanism includes a drive motor and a reducer connected to the output end of the drive motor. The output end of the reducer is provided with a drive gear, and the corresponding end of the take-up roller is provided with a driven gear that meshes with the drive gear.

[0009] Preferably, the upper end of the winding frame is provided with a U-shaped groove for supporting the winding roller, the outer side of the U-shaped groove is provided with a detachable anti-deviation baffle, and the upper part is provided with a detachable fixing block.

[0010] Furthermore, the take-up roller has anti-detachment protrusions evenly spaced on its surface, which cooperate with the inner wall of the take-up drum to transmit torque.

[0011] Preferably, the foil pressing roller and the tension adjusting roller are located on the same side of the horizontal axis and are respectively installed at the lower end of the side mounting rod.

[0012] Preferably, the foil strip tensioning mechanism is fixedly mounted on the winding machine frame via a bearing seat.

[0013] Preferably, the pressure roller is fixedly mounted on the winding machine frame via a bearing seat.

[0014] Preferably, the winding frame has support plates on both sides of the feed end, and feed rollers with the same height as the pressure roller are mounted on the support plates via bearing seats. The upper end of the support plate has a downward-facing mounting groove.

[0015] The beneficial effects of this utility model are as follows: 1. The foil tensioning mechanism uses the tension of a spring to force the foil tensioning roller to continuously and actively press against the surface of the foil roll being wound. When the foil tensioning roller is pulled towards the foil roll, the tension adjusting roller at the other end will inevitably tilt upward. This action lifts the incoming foil, and under the combined action of the pressure roller, the tension on the foil path is significantly increased. In addition, the foil tensioning roller prevents the outer layer of the foil from loosening, and the increased tension prevents the inner layer from loosening and shrinking due to insufficient tension. It can directly and effectively solve the problems of loosening, interlayer slippage, "necking" or overall shrinkage that easily occur when the foil is wound. 2. The U-shaped groove facilitates the quick placement of the take-up roller with bearing housing, the anti-deviation baffle effectively restricts the axial movement of the take-up roller, and the fixing block is fastened with bolts to provide final positioning. The entire take-up roller can be easily removed for roll change operations simply by removing the fixing block, which greatly improves production efficiency. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0018] Example like Figures 1-3 As shown, a winding machine for preventing foil from loosening and retracting includes a winding machine frame 1, a drive mechanism, a winding roller 2, a winding drum 3 detachably mounted on the winding roller 2, and a pressure roller 6, wherein the pressure roller 6 is located in front of the winding roller 2.

[0019] The winding frame 1 has support plates 7 on both sides of the feed end, and feed rollers 8 with the same height as the pressure roller 6 are installed on the support plates 7 through bearing seats.

[0020] The winding machine also includes a foil strip tensioning mechanism 9, which is fixedly mounted on the winding machine frame 1 via a bearing seat.

[0021] In this embodiment, the winding frame 1 consists of two parallel side plates and a square tube fixed to the lower end of the two side plates by bolts. Specifically, the winding roller 2, the pressure roller 6 and the foil tensioning mechanism 9 installed in conjunction with it maintain the structural stability of the winding frame 1.

[0022] The upper end of the winding frame 1 is provided with a U-shaped groove 11 for supporting the winding roller 2. A detachable anti-deviation baffle 12 is provided on the outside of the U-shaped groove 11, and a detachable fixing block 13 is provided on the top.

[0023] It should be further explained that by placing the take-up roller 2 with bearing housing on the U-shaped groove 11, and using the anti-deviation baffle 12 to further limit the left and right deviation of the take-up roller 2, and then fixing it with the fixing block 13, the take-up roller 2 can stably drive the take-up drum 3 to wind up the foil. Moreover, the take-up roller 2 can be removed by removing the fixing block 13, thereby replacing the take-up drum 3 that has not been wound with foil. Therefore, the entire take-up roller 2 can be easily removed for roll change operations simply by removing the fixing block 13, which greatly improves production efficiency.

[0024] The take-up roller 2 has anti-detachment protrusions 22 evenly spaced on its surface, which are used to cooperate with the inner wall of the take-up drum 3 to transmit torque. The drive mechanism includes a drive motor 5 and a reducer 4 connected to the output end of the drive motor 5. The output end of the reducer 4 is provided with a drive gear 41, and the corresponding end of the take-up roller 2 is provided with a driven gear 21 that meshes with the drive gear 41.

[0025] The pressure roller 6 is fixedly mounted on the winding machine frame 1 via a bearing seat.

[0026] The upper end of the support plate 7 has a downward-facing mounting groove 71, which allows the bearing seats at both ends of the feed roller 8 to be inserted into the mounting groove 71, thereby stabilizing the feed roller 8.

[0027] The foil strip tension pressing mechanism 9 is located between the take-up roller 2 and the pressure roller 6. The foil strip tension pressing mechanism 9 includes a horizontal shaft 91 rotatably mounted on the take-up frame 1, side rods 92 fixedly mounted at both ends of the horizontal shaft 91, foil pressing rollers 94 mounted at one end of the two side rods 92, and tension adjusting rollers 93 mounted at the other end of the two side rods 92, as well as an elastic traction assembly disposed between the take-up frame 1 and the side rods 92.

[0028] The elastic traction assembly is used to apply an elastic tension to the side mounting rod 92, causing the foil pressing roller 94 to continuously press against the foil roll surface on the take-up drum 3. Under the action of the elastic tension, the foil pressing roller 94 presses the foil roll surface, and at the same time the tension adjusting roller 93 is pulled up, thereby working in conjunction with the pressure roller 6 to increase the tension on the foil take-up path.

[0029] The elastic traction assembly includes a first hook 95 fixed to the side mounting rod 92, a second hook 97 fixed to the winding frame 1, and an elastic element 96 with its two ends respectively hooked to the first hook 95 and the second hook 97.

[0030] In this embodiment, the elastic element 96 is a spring.

[0031] The foil pressing roller 94 and the tension adjusting roller 93 are located on the same side of the horizontal axis 91 and are respectively installed at the lower end of the side mounting rod 92.

[0032] Specifically, by utilizing the contraction force of the elastic element 96, the side rod 92 can be pulled towards the take-up roller 2, causing the foil pressing roller 94 to press tightly against the surface of the foil roll on the take-up drum 3. Meanwhile, the tension adjusting roller 93 installed at the lower end of the side rod 92 is lifted by force, raising the input foil. This, together with the pressure roller 6, increases the tension of the foil, preventing the foil from loosening and causing the foil roll to retract.

[0033] like Figure 4As shown, in the winding operation state, under the contraction tension of the elastic element 96, the side rod 92 is pulled in the direction of arrow a. At this time, the foil strip tightening roller 94 continuously and actively presses against the surface of the foil strip roll being wound. When the foil strip tightening roller 94 is pulled towards the foil strip roll, the tension adjusting roller 93 at the other end will inevitably tilt upward. This action lifts the incoming foil strip. Under the combined action of the pressure roller 6, the tension on the foil strip path is significantly increased. The increased tension prevents the inner layer from loosening and shrinking due to insufficient tension. It can directly and effectively solve the problems of loosening, interlayer slippage, "necking" or overall shrinkage that easily occur when the foil is wound.

[0034] As the foil roll in the take-up drum 3 gradually increases in size, the force of the foil roll lifting the foil tension roller 94 is greater than the contraction tension of the elastic element 96. Therefore, the foil tension roller 94 is subjected to the tension in the direction of arrow a of the elastic element 96, and at the same time, it is also subjected to the lifting force in the direction of arrow b of the foil roll lifting the foil tension roller 94. At this time, the tension adjusting roller 93 will gradually rotate downward, which will not only adaptively adjust the tension, but also make it more conducive to the foil being wound up by the take-up drum 3.

[0035] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
