Description

Technical Field

[0001] This utility model relates to the field of material peeling machine technology, and more specifically, to a material peeling machine with double-sided feeding. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] Traditional stripper machines typically use a single-sided feeding method, processing only one strip at a time, resulting in low production efficiency. To increase capacity, some machines have attempted to use a dual-strip processing method, but since the two strips can only be loaded and unloaded from the same side, the loading and unloading processes interfere with each other. When loading or unloading is needed, it affects the operation of the other strip, impacting production efficiency and equipment stability.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that in the description of this utility model, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] like Figure 1-3 The invention shown is a dual-material stripping machine, which includes a frame 1 and a dual-material pulling roller assembly mounted on the frame 1. The dual-material pulling roller assembly includes a dual-material pulling main shaft 7 and a dual-material pulling auxiliary shaft 8.

[0034] like Figure 6-8As shown, the dual-material feeding spindle 7 includes a first spindle 71 and a second spindle 72. The first spindle 71 includes a first shaft end 711, a first shaft body 712, a first shaft journal 713, and a first shaft head 714. The diameter of the first shaft body 712 is larger than that of the first shaft end 711, the diameter of the first shaft body 712 is larger than that of the first shaft journal 713, and the diameter of the first shaft journal 713 is larger than that of the first shaft head 714. The second spindle 72 includes a second shaft body 721 and a second shaft head 722. The second spindle 72 is sleeved on the first shaft journal 713. The first shaft journal 713 extends from the second shaft head 722. A bearing is sleeved on the first shaft journal 713. 2. The bearing is rotatably mounted on the first journal 713. The first journal 713 is equipped with a first driven wheel 74. The second shaft head 722 is equipped with a second driven wheel 73. The frame 1 is also equipped with a first motor 5 and a second motor 6. The first motor 5 is used to drive the first driven wheel 74 to rotate, and the second motor 6 is used to drive the second driven wheel 73 to rotate. The dual-material stripper can be equipped with two material strips, namely a first material strip 21 and a second material strip 22. The first material strip 21 passes around the first main shaft 71 and is driven by the first main shaft 71. The second material strip 22 passes around the second main shaft 72 and is driven by the second main shaft 72.

[0035] like Figure 11 As shown, the dual-material pulling auxiliary shaft 8 includes a pulling auxiliary shaft center shaft 81, a first bushing 82 and a second bushing 83 sleeved on the pulling auxiliary shaft center shaft 81. The first bushing 82 is fixedly installed on the pulling auxiliary shaft center shaft 81, and the second bushing 83 is rotatably connected to the pulling auxiliary shaft center shaft 81 through a third bearing 84 and a fourth bearing 85. When the contact surfaces of the dual-material pulling auxiliary shaft 8 and the dual-material pulling main shaft 7 are pressed together, the first main shaft 71 clamps and pulls the first material strip 21 with the first bushing 82; the second main shaft 72 clamps and pulls the second material strip 22 with the second bushing 83 of the auxiliary shaft. The dual-material stripping machine of the present invention, through the design of the dual-material pulling roller shaft assembly, can simultaneously drive two rolls of material (the first material strip 21 and the second material strip 22) to run independently, realize synchronous stripping or composite processing, and improve production efficiency. In addition, this application adopts a dual-motor independent drive design, which allows the first spindle 71 and the second spindle 72 to run at different speeds, thereby meeting the differentiated stripping requirements of different material strips.

[0036] like Figure 4 and 5As shown, a feeding rack is installed on the frame 1. The feeding rack includes a feed rack 23 and a feeding shaft 2 extending in the front-to-back direction, mounted on the feed rack. The first feed strip 21 and the second feed strip 22 are rotatably mounted on the feeding shaft 2 from the front and rear sides, respectively. The feed rack 23 is mounted on the base plate, and the bottom of the feed rack 23 is fixed to the base plate by multiple triangular fasteners 24. The first feed strip 21 and the second feed strip 22 are in the form of a roll and are coaxially sleeved on the feeding shaft 2. The first feed strip 21, the first take-up tube 32, the first main shaft 71, and the first bushing 82 are aligned in a direction perpendicular to the feeding shaft 2; the second feed strip 22, the second take-up tube 33, the second main shaft 72, and the second bushing 83 are aligned in a direction perpendicular to the feeding shaft 2. The two systems can be controlled at their speeds separately to adapt to the processing needs of feed strips of different materials or thicknesses. The two rolls of material share the same feeding shaft 2, which ensures that the initial feeding position is consistent and avoids material belt deviation or uneven tension caused by different shafts.

[0037] like Figure 1 As shown, the frame 1 includes a back plate and a bearing 9 located on the front side of the back plate. The two ends of the double-material pulling main shaft 7 are respectively mounted on the bearing 9 and the back plate. Both the back plate and the bearing 9 are provided with arc-shaped grooves 91. The two ends of the pulling auxiliary shaft center shaft 81 are inserted into the arc-shaped grooves 91 and can move along the arc-shaped grooves 91. When the double-material stripper is in working condition, the two ends of the pulling auxiliary shaft center shaft 81 move along the arc-shaped grooves 91 to a state where the double-material pulling auxiliary shaft 8 and the double-material pulling main shaft 7 are pressed together. The material strip passes between the double-material pulling auxiliary shaft 8 and the double-material pulling main shaft 7 and is pulled and moved by the double-material pulling main shaft 7. When the double-material stripper is in material changing condition, the double-material pulling auxiliary shaft 8 moves along the arc-shaped grooves 91, so that a material passage gap is formed between the double-material pulling main shaft 7 and the double-material pulling auxiliary shaft 8. The arc-shaped groove 91 adjustment mechanism allows the dual-material feeding spindle 7 to quickly switch between working / material changing states, improving operational efficiency.

[0038] like Figure 9 and 10 As shown, the frame 1 is also equipped with two take-up shafts, namely a first take-up shaft 3 and a second take-up shaft 4. The take-up shaft includes a take-up center shaft 37, a first take-up tube 32 and a second take-up tube 33 sleeved on the take-up center shaft 37, and a pulley installed at the end of the take-up center shaft 37. The material strip includes first-layer waste and bottom-layer waste. The first take-up shaft 3 is used to wind the first-layer waste, and the second take-up shaft 4 is used to wind the bottom-layer waste.

[0039] A double-groove pulley 75 is also installed at the end of the first shaft head 714. The pulley of the first take-up shaft 3 is connected to the double-groove pulley 75 via a first belt 31. The pulley of the second take-up shaft 4 is connected to the double-groove pulley 75 via a second belt 41. The first motor 5 drives the first driven wheel 74 to rotate. The first driven wheel 74 drives the first main shaft 71 to rotate. The first main shaft 71 drives the first take-up shaft 3 and the second take-up shaft 4 to rotate. The first take-up tube 32... The inner wall of the second receiving tube 33 is provided with a damping friction material layer. The damping friction material layer enables the first receiving tube 32 and the second receiving tube 33 to form a frictional fit with the receiving center shaft 37. When there is a speed difference between the first receiving tube 32 and the second receiving tube 33 and the receiving center shaft 37, the first receiving tube 32 and the second receiving tube 33 can rotate relative to the receiving center shaft 37. The friction force generated by the damping friction material layer can realize the adaptive adjustment of the speed of the first receiving tube 32, the second receiving tube 33 and the receiving center shaft 37. Specifically, the set linear speeds of the first take-up shaft 3 and the second take-up shaft 4 are greater than the linear speeds of the first main shaft 71 and the second main shaft 72. After the frictional resistance generated by the material belt winding around the first take-up shaft 3 and the second take-up shaft 4, the actual linear speed of the first take-up tube 32 of the first take-up shaft 3 and the second take-up shaft 4 decreases to be equal to that of the first main shaft 71, and the actual linear speed of the second take-up tube 33 of the first take-up shaft 3 and the second take-up shaft 4 decreases to be equal to that of the second main shaft 72. A double-groove pulley 75 is provided at the end of the first main shaft 71, driving the first take-up shaft 3 through the first belt 31 and the second take-up shaft 4 through the second belt 41, so that a single first motor 5 can synchronously drive the first main shaft 71, the first take-up shaft 3, and the second take-up shaft 4, reducing the need for additional power sources. The theoretical linear speed set values ​​of the first take-up shaft 3 and the second take-up shaft 4 are higher than the main shaft's linear speed to ensure initial traction. During actual operation, due to the frictional resistance generated by the material belt winding, the actual linear speed of the take-up tube automatically decreases to be synchronized with the main shaft, forming a dynamic balance. This structure enables the strip to maintain constant tension during winding, avoiding problems such as strip deformation and breakage caused by loose winding or excessive winding.

[0040] The frame 1 is also equipped with a film-tearing platform 10 and a roller 20. The material strip passes sequentially through a first take-up shaft 3, a roller 20, the upper surface of the film-tearing platform 10, a dual-material pulling roller assembly, and a second take-up shaft 4. The first take-up shaft 3 is used to take up the first layer of waste material from the material strip, the film-tearing platform 10 is used for operation, and the second take-up shaft 4 is used to take up the bottom layer of waste material from the material strip. The dual-material pulling roller assembly is used to drive the material strip's movement.

[0041] The frame 1 is also provided with a vertically arranged film-tearing side plate located on the front side of the back plate. The front and rear ends of the film-tearing platform 10 are respectively installed between the film-tearing side plate and the back plate. The frame 1 also includes a rotating shaft 30, the front and rear ends of which are respectively installed between the back plate and the film-tearing side plate. After passing through the film-tearing platform 10, the material strip passes around the rotating shaft 30 and then passes through the dual-material pulling roller assembly.
