[0041] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] In the actual production process of battery materials, foil is needed as a material. Some rolled foils, such as copper foil or aluminum foil, need to be scrapped due to factors such as being too short or exceeding the shelf life.

[0043] Take copper foil as an example. Copper foil in rolls can be reused as raw materials for electrolytic copper foil. However, copper foil in rolls cannot be directly put into copper dissolving tanks for dissolution. Copper foil in rolls is usually rolled up neatly and tightly. Air cannot enter between each layer, making it difficult to oxidize and dissolve. As time goes by, more copper foil in rolls accumulates in the copper dissolving tank, which seriously affects the copper dissolving speed of the copper dissolving tank and directly affects production. Therefore, the copper foil in rolls needs to be peeled off and loosened before being put into the copper dissolving tank so that it can be fully oxidized and dissolved.

[0044] In the prior art, the foil is usually peeled off by cutting it with a wallpaper knife, which is inefficient. In addition, since the copper foil is relatively thin, smooth and tight, the sharp wallpaper knife or the foil cut can easily scratch your hands. In addition, the foil can be transferred to other equipment for processing. Since the rolled copper foil weighs several tons, the transfer process is time-consuming and labor-intensive, inefficient, and there are safety hazards.

[0045] In view of this, the utility model provides a foil stripping device, which does not require workers to manually tear the incision of the foil, avoids the risk of scratching hands, improves the safety of use, and does not require the foil roll to be transferred. The operation is convenient and quick, and is used to solve the technical problems of inconvenient foil stripping and poor safety.

[0046] The foil stripping device provided by the embodiment of the utility model is described below with reference to the accompanying drawings.

[0047] refer to Figure 1 and Figure 2 As shown, the utility model provides a foil stripping device, including: a fixed seat 10, a connecting frame 20 and a cutting assembly 30, the fixed seat 10 is provided with a through slot 11, the connecting frame 20 is arranged on the fixed seat 10, the cutting assembly 30 is arranged on the connecting frame 20, and the cutting assembly 30 extends into the through slot 11, and the cutting assembly 30 is used to cut the foil.

[0048] The utility model provides a foil stripping device, which opens a through slot 11 in a fixing seat 10, arranges a cutting assembly 30 on a connecting frame 20, and extends the cutting assembly 30 into the through slot 11, thereby fixing the cutting assembly 30. During the movement of the fixing seat 10, the cutting assembly 30 can move along with the fixing seat 10 and slide from one end of the foil roll to the other end of the foil roll along the axial direction of the foil roll, thereby cutting the foil. There is no need for workers to manually tear the incision of the foil, which avoids the risk of scratching hands, improves the safety of use, and there is no need to transfer the foil roll, so the operation is convenient and quick.

[0049] In one possible implementation, the foil stripping device further includes a telescopic member 40 , the two ends of which are respectively hinged to the connecting frame 20 and the cutting assembly 30 , the cutting assembly 30 is hinged to the connecting frame 20 , and the telescopic member 40 is configured so that the cutting assembly 30 extends into the through slot 11 .

[0050] The utility model provides a foil stripping device. Under the action of the telescopic member 40, the cutting assembly 30 extends into the through slot 11, and then cooperates with the movement of the fixing seat 10 to enable the cutting assembly 30 to cut the foil. The cut foil is stripped from the winding shaft without transferring the foil to other equipment for processing, which saves time and effort and improves the efficiency of foil stripping.

[0051] The utility model provides a foil stripping device, which does not require an operator to hold a wallpaper knife and tear a sharp foil cut, thereby effectively preventing the problem of the sharp wallpaper knife or the foil cut scratching the hand and improving the safety of use.

[0052] In a possible implementation, the telescopic member 40 may be a cylinder, a hydraulic cylinder or an electric telescopic rod. The telescopic member 40 can drive the cutting assembly 30 to cut the foil and prevent the cutting assembly 30 from being separated from the foil.

[0053] When the telescopic member 40 is extended, the telescopic member 40 pushes the cutting assembly 30 into the through slot 11, which can increase the cutting depth; conversely, when the telescopic member 40 is shortened, the telescopic member 40 drives the cutting assembly 30 to withdraw to the outside of the through slot 11, which can reduce the cutting depth, thereby realizing flexible adjustment of the cutting depth of the foil material, which is convenient to use.

[0054] In one possible implementation, the cutting assembly 30 includes a knife arm 31 and a cutter 32 , wherein a first end of the knife arm 31 is disposed on the connecting frame 20 , the cutter 32 is connected to a second end of the knife arm 31 , and the cutter 32 extends into the inner side of the through slot 11 .

[0055] In one possible implementation, the cutter 32 may be a blade, for example in the shape of a strip, one end of the cutter 32 is connected to the second end of the blade arm 31, the end of the cutter 32 away from the blade arm 31 may be in the shape of an acute angle, the side of the cutter 32 facing the fixed seat 10 is the blade surface, and the side of the cutter 32 facing away from the fixed seat 10 is the back side of the blade.

[0056] Considering that the cutter 32 is easily worn after long-term use, in order to facilitate the replacement of the cutter 32 and ensure the cutting effect, the cutter 32 can be detachably connected to the second end of the knife arm 31. For example, the cutter 32 can be connected to the second end of the knife arm 31 by a fastener such as a screw.

[0057] In a possible implementation, the cutter 32 is circular, rotatably disposed at the second end of the knife arm 31, and has a blade at the edge of the cutter 32. With this structure, when the foil stripping device as a whole moves along the axial direction of the foil roll, the cutter 32 rotates to cut the foil roll along the axial direction of the foil roll, which can reduce the wear of the cutter 32 on the one hand, and reduce the thrust for pushing the foil stripping device as a whole to move along the axial direction of the foil roll on the other hand.

[0058] The cutter 32 has a mounting hole at its center, and the side wall of the second end of the knife arm 31 has a mounting shaft, the center axis of the mounting shaft is perpendicular to the axial direction of the foil, and the mounting hole of the cutter 32 is sleeved on the outer peripheral surface of the mounting shaft, so that when the foil stripping device as a whole moves along the axial direction of the foil roll, the cutter 32 rotates along the axial direction of the foil roll to cut the foil.

[0059] The mounting hole is located at the center of the cutter 32. When the cutter 32 rotates along the mounting axis, the cutter 32 is prevented from jumping. This is beneficial for maintaining the cutting depth of the cutter 32 consistent and achieving continuous cutting when the foil stripping device as a whole moves along the axial direction of the foil roll.

[0060] The cutter 32 may be made of tungsten steel, which has the characteristics of high hardness, wear resistance, strength and toughness.

[0061] In a possible implementation, the second end of the knife arm 31 has a motor, and the output shaft of the motor is connected to the cutter 32. The motor is used to drive the cutter 32 to rotate, so that the cutting of the foil roll is time-saving and labor-saving.

[0062] In one possible implementation, along the first direction, the projection of the inner wall surface of the fixing seat 10 is in an arc shape, that is, the inner wall surface of the fixing seat 10 is arched. This is because the outer surface of the foil roll is in an arc shape, so that the inner wall surface of the fixing seat 10 and the outer surface of the foil roll can better fit.

[0063] In one possible implementation, along the first direction, the projection of the inner wall surface of the fixing seat 10 may be 1 / 6 times, 1 / 5 times, or 1 / 4 times the entire circumference, which helps the fixing seat 10 to be suitable for foil rolls with different outer diameters.

[0064] In a possible implementation, the outer wall surface of the fixing seat 10 may be an arc surface or a plane surface.

[0065] The through slot 11 passes through the inner wall and the outer wall of the fixing seat 10 , so that the cutting assembly 30 can extend into the inner side of the fixing seat 10 through the through slot 11 and be inserted into the foil roll located inside the fixing seat 10 .

[0066] The through slot 11 may be a rectangular slot or a waist-shaped slot, and the length direction of the through slot 11 is arranged along the first direction. Under the action of the telescopic member 40, the cutting assembly 30 swings around the position where the crossbeam 22 hinges the cutting assembly 30, and the cutter 32 moves in the through slot 11. Of course, the through slot 11 may also be in other shapes, such as an elliptical slot.

[0067] Along the first direction, both ends of the through slot 11 may be limit surfaces, and the through slot 11 may be used to limit the sliding range of the cutter 32 along the first direction to prevent the cutter 32 from escaping from the through slot 11, thereby ensuring that the foil can be cut.

[0068] In one possible implementation, reference Figure 1 and Figure 2 As shown, the connecting frame 20 includes a crossbeam 22 and at least one column 21 . The column 21 is connected between the crossbeam 22 and the outer wall surface of the fixing seat 10 . The cutting assembly 30 and the telescopic member 40 are both hinged to the crossbeam 22 .

[0069] The column 21 may be a rectangular column or a circular column, and the bottom of the column 21 may be integrally connected to the fixing base 10. Of course, the bottom of the column 21 may also be connected to the fixing base 10 by welding or screw connection.

[0070] The included angle between the column 21 and the cross beam 22 may be, for example, 89°, 90° or 91°, and the cross beam 22 extends along the first direction.

[0071] The cross beam 22 has a lug on one side facing the fixed seat 10, and the first end of the knife arm 31 can be a lug hinged to the cross beam 22 through a first rotating shaft, and the first rotating shaft is passed through the first end of the knife arm 31 and the lug, so that the knife arm 31 can swing around the first rotating shaft. The first rotating shaft can be a pin or a pin shaft, etc.

[0072] The cutting assembly 30 , part of the telescopic member 40 and part of the cross beam 22 form a triangle shape.

[0073] In order to improve the stability of the connecting frame 20, there are two columns 21, which are arranged at intervals on the outer wall of the fixing seat 10 along the first direction, and the crossbeam 22 is connected between the two columns 21. The through slot 11 is located between the two columns 21.

[0074] In a possible implementation, the foil stripping device further includes an operating member 50, which is disposed on the outer wall of the fixed seat 10. The operating member 50 is provided to facilitate pushing or pulling the fixed seat 10 along the axial direction of the foil roll through the operating member 50 to achieve movement of the fixed seat 10.

[0075] The operating member 50 may be an operating handle, and the operating handle may be in a rod shape or a curved shape. The operating member 50 may be connected to the outer wall surface of the fixing seat 10 by welding or screw connection.

[0076] In a possible implementation, the foil stripping device further includes a handle 60, which is disposed on the outer wall of the connecting frame 20 or the fixing seat 10. The handle 60 is provided to facilitate the movement of the foil stripping device, so that after use, the foil stripping device can be taken away as a whole, and before use, the foil stripping device can be moved and placed on the foil roll.

[0077] In a possible implementation, the cutting assembly 30 and the telescopic member 40 are both hinged to the crossbeam 22, and along the first direction, the position where the crossbeam 22 is hinged to the cutting assembly 30 is spaced from the position where the crossbeam 22 is hinged to the telescopic member 40. This is to drive the cutting assembly 30 to cut the foil roll by means of the telescopic movement of the telescopic member 40.

[0078] In a possible implementation, a ball bearing is embedded in the fixing seat 10, and part of the ball bearing extends out of the inner wall surface of the fixing seat 10. The inner wall surface of the fixing seat 10 is the surface of the fixing seat 10 that is in contact with the foil roll. Such a structure can reduce the friction between the fixing seat 10 and the foil roll during the axial movement of the fixing seat 10 along the foil roll, so that the movement of the fixing seat 10 is smoother and it is more labor-saving to push the fixing seat 10 to move.

[0079] In a possible implementation, four balls are embedded in the fixing seat 10, and the four balls can be distributed at the four corners of the fixing seat 10, which helps to improve the balance of the movement of the fixing seat 10 and prevent the fixing seat 10 from tilting. Of course, the number of balls can be more to improve the smoothness of the movement of the fixing seat 10 on the outer wall of the foil roll.

[0080] In order to facilitate the installation of the ball, a rolling groove can be opened on the inner wall surface of the fixing seat 10, and the ball is arranged in the rolling groove so that the bottom end of the ball is exposed from the rolling groove.

[0081] During operation, the shielding effect of the fixing seat 10 can also prevent the cutter 32 from contacting the worker's hand, thereby avoiding the risk of cutting the hand and improving the safety of use.

[0082] The utility model provides a foil stripping device which can realize stable cutting of a foil roll. By changing the telescopic length of the telescopic member 40, the cutting depth of the foil can be controlled. The utility model is safe, reliable and has strong applicability.

[0083] The utility model provides a foil stripping device which is compact and easy to carry. The foil roll is not slipped during cutting. The cutting assembly 30 fits tightly with the rolled foil roll, and the cutting depth of the cutter 32 can be controlled by hand force.

[0084] When in use, a foil stripping device provided by the utility model is placed on a foil roll, the fixing seat 10 is tightly fitted with the foil roll, the operating member 50 is held by hand, a small force is applied to the fixing seat 10, and the fixing seat 10 is pulled, so that the cutter 32 of the cutting assembly 30 opens a cutting opening from the end face of the foil roll, and moves from one end of the foil roll to the other end of the foil roll along the axial direction of the foil roll, cutting several layers of the foil roll, completing the integrated operation of cutting and stripping, and the stripped foil is in the form of independent sheets, which can be directly placed in a copper melting tank for dissolution.

[0085] After peeling off several layers of foil, the foil peeling device is placed on the remaining foil roll for secondary cutting. When encountering a thick roll or a wide roll, the operation is repeated many times until the reel in the center of the foil roll is exposed, thus realizing the peeling operation of the entire foil roll from the inside to the outside, improving the peeling efficiency of the foil roll and saving time and effort.

[0086] By controlling the force applied by the hand to the operating member 50 , the cutting depth of the foil roll by the cutter 32 can be controlled.

[0087] When the operating member 50 applies a large force to the fixed seat 10, the knife arm 31 contracts. On the one hand, the knife arm 31 plays a supporting role. On the other hand, the knife arm 31 responds to the force applied by the operating member 50 to ensure the working stability of the foil stripping device. The knife arm 31 fluctuates up and down in the through groove 11 according to the force applied by the operating member 50. The cutter 32 is fixed at the bottom of the knife arm 31, and the cutter 32 rotates and cuts, cutting the foil back and forth.

[0088] The utility model provides a foil stripping device with a compact structure and convenient carrying. The foil can be processed in real time without being transferred to a specific place for cutting. The device is easy to operate and has strong applicability, and is applicable to waste foil rolls of various different materials.

[0089] The utility model provides a foil stripping device which can replace manual tearing and stripping of foil, thereby improving the foil stripping efficiency, solving the problem of easy injury caused by manual foil stripping, and having better safety.
