Description

Technical Field

[0001] This utility model relates to the field of material stripping equipment technology, and more specifically, to a material stripping equipment with dual material belts. 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] In existing industrial production, strip stripping is a critical step in many manufacturing processes. For example, in industries such as lithium battery electrode production, flexible circuit board processing, and tape lamination, it is often necessary to strip or laminate materials such as protective films and substrates. Traditional stripping machines typically use a single-strip design, processing only one roll of strip at a time. When the production process requires processing two rolls of strips of different materials or specifications simultaneously, two independent machines are often required. This not only increases equipment costs and floor space but also leads to low production efficiency and poor operational coordination.

[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.

[0006] To solve the above-mentioned technical problems, this utility model provides a double-material stripping device. The stripping device includes a frame and a double-material pulling roller assembly mounted on the frame. The double-material pulling roller assembly includes a double-material pulling main shaft and a double-material pulling auxiliary shaft. The double-material pulling main shaft includes a first main shaft and a second main shaft coaxially arranged. A first motor and a second motor are also mounted on the frame. The first motor drives the first main shaft, and the second motor drives the second main shaft. The stripping device can accommodate two strips, namely a first strip and a second strip. The frame is also equipped with... There are two take-up shafts, namely a first take-up shaft and a second take-up shaft. Each take-up shaft includes a take-up center shaft, a first take-up tube and a second take-up tube sleeved on the take-up center shaft, and a pulley installed at the end of the take-up center shaft. The material strip includes a first layer of waste material and a bottom layer of waste material. The first take-up tube of the first take-up shaft is used to wind the first layer of waste material of the first material strip, and the first take-up tube of the second take-up shaft is used to wind the bottom layer of waste material of the first material strip. The second take-up tube of the first take-up shaft is used to wind the first layer of waste material of the second material strip, and the second take-up tube of the second take-up shaft is used to wind the bottom layer of waste material of the second material strip.

[0007] Preferably, the first spindle sequentially includes a first shaft end, a first shaft body, and a first shaft journal. The diameter of the first shaft body is larger than that of the first shaft end, and the diameter of the first shaft body is larger than that of the first shaft journal. The second spindle includes a second shaft body and a second shaft head. The second spindle is sleeved on the first shaft journal, and the first shaft journal extends from the second shaft head. A bearing is sleeved on the first shaft journal, and the second spindle is rotatably mounted on the first shaft journal via the bearing. A first driven wheel is mounted on the first shaft journal, and a second driven wheel is mounted on the second shaft head. The first motor is used for driving. The first driven wheel rotates, and the second motor drives the second driven wheel to rotate. The dual-material pulling sub-shaft includes a pulling sub-shaft central shaft, a first bushing and a second bushing sleeved on the pulling sub-shaft central shaft. The first bushing is fixedly installed on the pulling sub-shaft central shaft, and the second bushing is rotatably connected to the pulling sub-shaft central shaft through a third bearing and a fourth bearing. When the contact surfaces of the dual-material pulling sub-shaft and the dual-material pulling main shaft are pressed together, the first main shaft clamps and pulls the first material strip with the first bushing; the second main shaft clamps and pulls the second material strip with the second bushing of the sub-shaft.

[0008] Preferably, a feeding shaft is installed on the frame, and the first and second material strips are rotatably mounted on the feeding shaft. The first and second material strips are in the shape of a roll and are coaxially sleeved on the feeding shaft. The first material strip, the first take-up tube, the first main shaft, and the first bushing are aligned in a direction perpendicular to the feeding shaft. The second material strip, the second take-up tube, the second main shaft, and the second bushing are aligned in a direction perpendicular to the feeding shaft.

[0009] Preferably, the frame includes a back plate and a bearing seat located on the front side of the back plate. The two ends of the dual-material pulling main shaft are respectively mounted on the bearing seat and the back plate. Both the back plate and the bearing seat are provided with arc-shaped grooves. The two ends of the central shaft of the pulling auxiliary shaft are inserted into the arc-shaped grooves and can move along the arc-shaped grooves. When the stripping equipment is in working condition, the two ends of the central shaft of the pulling auxiliary shaft move along the arc-shaped grooves to a state where the dual-material pulling auxiliary shaft and the dual-material pulling main shaft are pressed together. The material strip passes between the dual-material pulling auxiliary shaft and the dual-material pulling main shaft and is pulled and moved by the dual-material pulling main shaft. When the stripping equipment is in material changing condition, the dual-material pulling auxiliary shaft moves along the arc-shaped grooves, so that a material passage gap is formed between the dual-material pulling main shaft and the dual-material pulling auxiliary shaft.

[0010] Preferably, the first main shaft further includes a first shaft head, which is disposed at the end of the first journal. The diameter of the first journal is larger than that of the first shaft head. A double-groove pulley is also installed at the end of the first shaft head. The pulley of the first take-up shaft is connected to the double-groove pulley via a first belt. The pulley of the second take-up shaft is connected to the double-groove pulley via a second belt. The first motor drives the first driven wheel to rotate. The first driven wheel drives the first main shaft to rotate. The first main shaft drives the first take-up shaft and the second take-up shaft to rotate. The inner walls of the first take-up tube and the second take-up tube are provided with a damping friction material layer. The damping friction material layer enables frictional engagement between the first take-up tube and the second take-up tube and the take-up center shaft. When there is a speed difference between the first take-up tube and the second take-up tube and the take-up center shaft, relative rotation can occur between the first take-up tube and the second take-up tube and the take-up center shaft. The frictional force generated by the damping friction material layer can achieve adaptive adjustment of the speed of the first take-up tube, the second take-up tube, and the take-up center shaft.

[0011] Preferably, the set linear speed of the first take-up shaft and the second take-up shaft is greater than the linear speed of the first main shaft and the second main shaft. After the frictional resistance generated by the material belt winding around the first take-up shaft and the second take-up shaft, the actual linear speed of the first take-up tube of the first take-up shaft and the second take-up shaft is reduced to be equal to that of the first main shaft, and the actual linear speed of the second take-up tube of the first take-up shaft and the second take-up shaft is reduced to be equal to that of the second main shaft.

[0012] Preferably, the frame is further provided with a film-tearing platform, and the material strip passes sequentially through the first take-up shaft, the upper surface of the film-tearing platform, the double material pulling roller shaft assembly, and the second take-up shaft. The frame is also provided with a vertically arranged film-tearing side plate located on the front side of the back plate, and the front and rear ends of the film-tearing platform are respectively installed between the film-tearing side plate and the back plate.

[0013] Preferably, the frame further includes a rotating shaft, with its front and rear ends respectively installed between the back plate and the film-tearing side plate. After passing through the film-tearing platform, the material strip passes around the rotating shaft and then passes through the dual-material pulling roller assembly.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that in the description of this invention, 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 invention, unless otherwise stated, "a plurality of" means two or more.

[0032] like Figure 1-3 The invention shown is a dual-material stripping device, 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.

[0033] like Figure 4-6 As 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 stripping device 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.

[0034] like Figure 9As shown, the dual-material pulling auxiliary shaft 8 includes a central shaft 81, a first bushing 82 and a second bushing 83 sleeved on the central shaft 81. The first bushing 82 is fixedly installed on the central shaft 81, and the second bushing 83 is rotatably connected to the central shaft 81 via 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 device 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, realizing synchronous stripping or composite processing and improving 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.

[0035] A feeding shaft 2 is mounted on the frame 1. The first material strip 21 and the second material strip 22 are rotatably mounted on the feeding shaft 2. The first material strip 21 and the second material strip 22 are in the form of rolls and are coaxially sleeved on the feeding shaft 2. The first material 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 material 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 control their speeds separately to adapt to the processing requirements of material strips of different materials or thicknesses. The two rolls of material share the same feeding shaft 2, ensuring that the initial feeding position is consistent and avoiding material strip offset or uneven tension caused by different shafts.

[0036] 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 stripping equipment 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 stripping equipment 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.

[0037] like Figure 7 and 8 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
