Description

TECHNICAL FIELD

[0001] The utility model belongs to the production technical field of composite current collector, specifically relates to a fixed structure of over roller edge. BACKGROUND

[0002] In the current film production process, the unwinding operation of the horizontal coating line is a key link. In the actual production process, the unwinding pressure point abnormality is often encountered, which has an adverse effect on the normal unwinding of the film and the subsequent coating process. In order to solve the problem of unwinding pressure point abnormality, the existing technology adopts the method of sleeving the mesh cover on the over roller at the unwinding end, and practice proves that this method can indeed effectively solve the problem of unwinding pressure point abnormality to a certain extent. However, in the process of using this mesh cover to assist in solving the unwinding pressure point abnormality, the following problems have appeared:

[0003] 1. The cable is easy to shift: the cable is used to fix the mesh cover sleeved on the over roller at the unwinding end, and the stability of the cable itself is poor, which is easy to shift in the production process. This shift is difficult to effectively control and avoid, thereby laying hidden dangers for a series of subsequent problems.

[0004] 2. High risk of film rupture: after the mesh cover is loose, uneven force or abnormal friction will be generated on the film during the unwinding process, which makes the film at the unwinding end prone to rupture. Film rupture is a serious production accident, which directly destroys the continuity of production.

[0005] 3. Serious waste of production materials: each film rupture means that the part of the production materials being processed cannot continue to complete the subsequent process, and can only be discarded, resulting in a lot of unnecessary waste of production materials and increasing the production cost.

[0006] 4. Interruption of production process: film rupture will inevitably force the entire production process to be interrupted, and the related equipment needs to be shut down for troubleshooting, cleaning and re-preparation, which seriously affects the production efficiency, makes the production plan unable to proceed as expected, and may cause a series of problems such as order delivery delay.

[0007] In summary, in the production process, the mesh cover is easy to shift when fixed by the cable, which makes the mesh cover loose and unstable, and further causes the film at the unwinding end to rupture. Film rupture not only causes serious waste of production materials, but also forces the entire production process to be interrupted, greatly affects the production efficiency, increases the production cost, and becomes a technical problem to be solved in the current horizontal coating line production process. UTILITY MODEL CONTENTS

[0008] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a fixed structure of over roller edge.

[0009] To achieve the above object and other related objects, the technical scheme of the utility model provides a kind of over roller edge fixed structure, including the over roller body for conveying film, the over roller body is equipped with elastic sleeve at unwinding end, and the elastic sleeve is tightened in the unwinding end of the over roller body by a fastener;The unwinding end of the over roller body is also provided with a limiting piece, and the limiting piece is arranged on the elastic sleeve.

[0010] In the present scheme, a limiting piece is arranged at the unwinding end of the over roller body, even if the fastener is displaced during production, the displacement range can be effectively limited by the limiting piece, so that it will not extend to the forming area, thereby avoiding a series of problems such as film rupture caused by the displacement of the fastener to the forming area, which affects the normal production.

[0011] Further, the limiting piece is a winding band-shaped body with adhesive layer on one side.In the present scheme, the limiting piece is a winding band-shaped body, which is easy to operate and low in cost, and the adhesive layer on one side of the limiting piece can ensure firm adhesion and ensure the limiting effect.

[0012] Further, the length of the over roller body is L1, the incoming length of the film is L2, and the length of the limiting piece from the proximal end surface of the over roller body is D, and 2D

[0013] Further, the limiting piece is fixed on the elastic sleeve in a completely overlapping winding manner.In the present scheme, the limiting piece is wound on the elastic sleeve in a completely overlapping manner, which ensures the stability of the limiting.

[0014] Further, the number of winding turns of the limiting piece is Q, and 3≤Q≤10.In the present scheme, the number of winding turns of the limiting piece is not less than 3 turns, which can ensure the firmness of the limiting piece after winding, and the number of winding turns is not more than 10 turns, which can avoid material waste.

[0015] Further, a limiting groove is formed in the unwinding end of the over roller body along its circumference, and the groove width and opening position of the limiting groove are correspondingly arranged with the limiting piece, and the limiting piece is embeddedly arranged in the limiting groove.In the present scheme, the limiting groove is formed in the unwinding end and the limiting piece is embedded in the limiting groove, which improves the stability of the limiting structure.

[0016] Further, the winding thickness of the limiting piece is T1, and T1≥3mm;The groove depth of the limiting groove is T2, and T2≤3mm.In the present scheme, the groove depth of the limiting groove is not greater than the winding thickness of the limiting piece, which avoids the damage to the elastic sleeve during installation of the limiting piece due to the excessive depth of the limiting groove.

[0017] Further, the opening of the limiting groove is provided with a rounded corner. In this scheme, the limiting groove opening is provided with a rounded corner, which can avoid scratching the elastic sleeve body when the limiting piece is wound around the elastic sleeve body.

[0018] Further, the width W of the limiting piece is 10mm~20mm. In this scheme, the limiting piece adopts a width not more than 20mm, which can avoid limiting the axial distance of the over roller body too much to affect the conveying of the film, and also avoid causing material waste.

[0019] Further, the limiting piece is a masking tape. In this scheme, the masking tape is resistant to high temperature and chemical solvents, and has good adhesion and simple use.

[0020] Due to the use of the above technical scheme, the present application has the following beneficial effects compared with the prior art:

[0021] 1. The structure designed in the present application can stabilize the state of the elastic sleeve body: the limiting piece is wound to a specific thickness on both sides of the over roller with the elastic sleeve body at the unwinding end, which increases the limiting, effectively limits the displacement range of the fastener, and avoids the loosening of the elastic sleeve body caused by the displacement of the fastener. The elastic sleeve body can maintain a relatively stable state, thereby exerting a relatively uniform force on the film during unwinding, greatly reducing the risk of film rupture caused by uneven force or abnormal friction due to loosening of the elastic sleeve body.

[0022] 2. The structure designed in the present application can ensure the continuity of production: since the possibility of film rupture is effectively reduced, the production material being processed can smoothly pass through the unwinding and subsequent processes, reducing the situation that the material being processed has to be discarded due to film rupture, thereby significantly reducing the waste of production materials and helping to save production costs.

[0023] 3. The structure designed in the present application can avoid process interruption: film rupture often forces the entire production process to be interrupted, requiring a large amount of time for fault diagnosis, cleaning and re-preparation after equipment shutdown. This scheme reduces the risk of film rupture, effectively avoids such production process interruption, enables production to continue smoothly according to the plan, and thus improves production efficiency, helping to ensure that orders can be delivered on time.

[0024] 4. The structure is easy to implement: the scheme of winding the limiting piece to a specific thickness on both sides of the roller is relatively simple and easy to implement, without the need for large-scale modification of existing equipment or the use of overly complex technical means. Enterprises can conveniently operate and implement according to the scheme in the actual production process, and can be quickly applied to the existing horizontal film coating line unwinding end related process, and has good operability and practicality.

[0025] 5. The structure of the utility model design takes into account the short-term and long-term: the current limiting piece winding scheme can be used as a transitional measure to effectively solve the problem of film rupture caused by fastener displacement in the short term, while meeting the current production needs and reducing production failures, it also lays a foundation for subsequent more thorough and optimized equipment improvement, so that enterprises can gradually promote technology upgrading without affecting current production.

[0034] Example 1:

[0035] See appendix Figure 1 As shown, this embodiment provides a roller edge fixing structure, including a roller body 1 for conveying film. An elastic sleeve 2 is fitted onto the unwinding end of the roller body 1, and the elastic sleeve 2 is fastened to the unwinding end of the roller body 1 by a fastener 3. A limiting member 4 is also provided at the unwinding end of the roller body 1, and the limiting member 4 is disposed on the elastic sleeve 2. By providing the limiting member 4 at the unwinding end of the roller body 1, even if the fastener 3 shifts during production, its shift range can be effectively limited by the limiting member 4, preventing it from extending into the forming area. This avoids a series of problems affecting normal production, such as film breakage, caused by the fastener 3 shifting into the forming area.

[0036] The elastic sleeve 2 can be, but is not limited to, a nylon mesh cover with a certain degree of elasticity and wear resistance. Any material and elasticity that can meet the requirements of assisting unwinding on the unwinding end roller can be selected.

[0037] Fastener 3 can be, but is not limited to, cable ties; any structure that can fasten the elastic sleeve 2 without damaging the roller body 1 can be used.

[0038] The limiting member 4 is a single-sided adhesive layer provided with a winding belt body. The limiting member 4 adopts a winding belt body, which is convenient to operate and low in cost. The limiting member 4 is provided with a single-sided adhesive layer, which can ensure firm adhesion and limiting effect. The width W of the limiting member 4 is 10 mm-20 mm, and the width of the limiting member 4 is 10 mm, 12 mm, 15 mm, 18 mm or 20 mm. The limiting member 4 adopts a width of not more than 20 mm, which can avoid affecting the transmission of the film due to excessive axial distance limiting of the over roller body 1, and also avoid material waste.

[0039] The limiting member 4 can be, but is not limited to, a masking tape. The masking tape is resistant to high temperature and chemical solvents, and has good adhesion and simple and convenient use.

[0040] The limiting member 4 is fixed on the elastic sleeve body 2 in a completely overlapping winding manner. The limiting member 4 is wound on the elastic sleeve body in a completely overlapping manner, which ensures the stability of the limiting. The number of winding turns of the limiting member 4 is Q, and 3≤Q≤10. The number of winding turns of the limiting member 4 is not less than 3 turns, which can ensure the firmness of the limiting member 4 after winding; and the number of winding turns is not more than 10 turns, which can avoid material waste.

[0041] The length of the over roller body 1 is L1, the incoming length of the film is L2, the length of the limiting member 4 from the proximal end surface of the over roller body 1 is D, and 2D DETAILED DESCRIPTION

[0043] 1. Prepare an appropriate amount of masking tape, the width of which should be selected according to the size of the over roller and the convenience of actual winding operation. Generally, a masking tape with a width of about 10 mm-20 mm can be selected to ensure that it can be completely wound on both sides of the over roller and reach the required thickness.

[0044] 2. Confirm that the mesh cover used is of good quality, has no damage, filament extraction, etc., and its material and elasticity can meet the needs of assisting unwinding on the unwinding end over roller.

[0045] 3. Prepare a conventional cable tie, the length and width of which should be suitable for fixing the position of the mesh cover on the over roller, and at the same time, the material of the cable tie should have a certain toughness to firmly bind the mesh cover. However, attention should also be paid to the fact that the displacement of the cable tie in the subsequent production process is one of the key problems to be solved by the utility model.

[0046] 4. At the unwinding end of the horizontal coating line, first ensure that the over roller with the mesh cover at the unwinding end is clean, free of oil stains and debris, so as to avoid affecting the adhesion effect of the masking tape and the normal work of the mesh cover and the cable tie. Clean cloth can be used to dip an appropriate amount of cleaning solvent (such as alcohol, etc.) to wipe the surface of the over roller, and wait for the surface of the over roller to dry completely after wiping.

[0047] 5. At both sides of the over roller with the mesh cover at the unwinding end, accurately measure the position 20mm away from the edge of the over roller. A tape measure or other suitable measuring tool can be used for measurement and positioning.

[0048] 6. Tear off a section of masking tape from the masking tape roll, align one end of the masking tape with the edge of the over roller at the measured 20mm position, and start winding around the over roller at a uniform speed and force. During the winding process, attention should be paid to the close fit between the masking tapes to avoid gaps or wrinkles, so as to avoid affecting the limiting effect.

[0049] 7. Continue to wind the masking tape, and use a thickness measuring tool (such as a caliper, etc.) to measure the thickness of the wound masking tape in real time, so that it meets the requirement of 3mm. If the thickness is found to be insufficient during winding, the number of winding layers can be appropriately increased or the tightness of winding can be adjusted until the specified thickness is reached.

[0050] 8. Put the mesh cover on the over roller that has completed the winding of the masking tape, and make sure that the mesh cover covers the surface of the over roller evenly and smoothly, without twisting or accumulation.

[0051] 9. Use the cable tie to fix the mesh cover, pass the cable tie through the mesh cover and around the over roller, and bind it at the appropriate position. The binding force should be moderate, which can ensure that the mesh cover is firmly fixed on the over roller, and also cannot damage the mesh cover or affect its elasticity due to too tight binding. Usually, cross binding or other conventional fixing methods can be used, but attention should be paid to whether the cable tie has shifted during the subsequent production process.

[0052] Example Two:

[0053] Referring to the drawings Figure 2As shown, the embodiment is a further improvement based on the first embodiment, and the specific method is that a limiting groove 5 is formed in the circumference of the unwinding end of the roller body 1, the groove width and the opening position of the limiting groove 5 are correspondingly arranged with the limiting piece 4, and the limiting piece 4 is embeddedly arranged in the limiting groove 5. The limiting groove 5 is opened at the unwinding end, and the limiting piece 4 is embedded in the limiting groove 5 for installation, thereby improving the stability of the limiting structure. The winding thickness of the limiting piece 4 is T1, and T1≥3mm; the groove depth of the limiting groove 5 is T2, and T2≤3mm. The groove depth of the limiting groove 5 is not greater than the winding thickness of the limiting piece 4, so as to avoid that the limiting piece 4 is damaged when installed due to the too large depth of the limiting groove 5. The opening of the limiting groove 5 is provided with a rounded corner 6. The rounded corner 6 arranged at the opening of the limiting groove 5 can avoid scratching the elastic sleeve body 2 when the limiting piece 4 winds the elastic sleeve body 2.

[0054] The over roller edge fixing structure designed in the utility model sets a limiting piece at the unwinding end of the over roller body, effectively limits the displacement range of the fastener, avoids that the elastic sleeve body is loosened due to the displacement of the fastener, even if the fastener is displaced during the production process, the displacement range of the fastener can be effectively limited by the limiting piece, so that the fastener will not extend to the forming area, thereby avoiding that a series of problems such as film rupture are caused due to the displacement of the fastener to the forming area, and affecting the normal production.

[0055] The above embodiments are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model.
