Description

Technical Field

[0001] The invention belongs to the technical field of cable production, and in particular relates to a cable core coating molding device for cable production. Background Art

[0002] When processing existing wires and cables, it is necessary to coat the core wires, but currently most of the coating treatments are directly injected with liquid sheath raw materials on the outside of the core wires, and then the raw materials are cooled and formed; for example, the Chinese patent with application number CN202310564442.8 discloses a coating device with high stability for cable production, which specifically relates to the field of cable production technology, including a device base, a support device is provided on the left side of the upper end of the device base, and a conical barrel is provided on the upper ends of the two second support frames, and two third support frames are symmetrically provided on the right side of the upper end of the device base, and the upper ends of the two third support frames are provided with a mounting barrel, and a plurality of spray heads are provided in a circular array on the left side of the inner cavity of the mounting barrel, and a cooling pipe is provided on the right side of the inner cavity of the mounting barrel. The supporting device includes two first support frames, and a first supporting ring is provided on the upper end of the first support frame, and an inner gear ring is provided in the second mounting groove, and a plurality of guide devices are provided in a circular array in the inner cavity of the first mounting groove. The coating device with high stability for cable production described in the present invention adopts the design of the support device and the conical barrel so that the device can be applied to cables with different numbers of cells, which increases the applicability of the device when used.

[0003] In the above patent, the battery cells are inserted into the second support ring, and the second support rings are driven by the guiding device to bring the battery cells closer to each other for folding; however, in the above patent, when folding, only the battery cells whose diameters are equal to the inner diameters of the second support rings have a better folding effect. If the battery cell diameter is smaller than the inner diameter of the second support ring, the battery cell can swing freely on the inner side of the second support ring, and the distribution positions of the battery cells after folding are uncertain, resulting in that the battery cells after folding may not be evenly distributed in a ring shape around the central axis of the conical barrel, which in turn causes problems such as poor folding effect and uneven subsequent spraying; therefore, there is a problem in the prior art that it is only suitable for folding and coating battery cells of a specific diameter.

[0037] The first support ring 401 is provided with an inner lining core 600 coaxially placed with the first support ring 401, and a plurality of placement grooves 601 evenly distributed in an annular shape are provided on the outer peripheral wall of the inner lining core 600. The placement grooves 601 are equal in number and correspond one to one with the pressure strips 403. The placement grooves 601 are coaxially placed with the inner lining core 600, and the placement grooves 601 are coaxially placed with the battery cells 700. The peripheral walls of the placement grooves 601 are in contact with the peripheral walls of the battery cells 700, and the peripheral walls of two adjacent battery cells 700 are tangent to each other, and the pressure strips 403 are in contact with the peripheral walls of the corresponding battery cells 700 away from the inner lining core 600.

[0038] The device is used in conjunction with a pulling device in the prior art. After the battery cells 700 and the inner lining core 600 are gathered and compacted by the gathering mechanism, the gathered battery cells 700 and the inner lining core 600 are sequentially passed through the first support ring 401 and the second support ring 501, and connected to the pulling device in the prior art. The pulling mechanism pulls the battery cells 700 and the inner lining core 600 to continuously pass through the spraying mechanism, and the coating material is sprayed on the outer surface of the assembly of the battery cells 700 and the inner lining core 600 by the spraying mechanism.

[0039] In the present application, the inner lining wire is prefabricated according to the diameter of the gathered battery cell 700;

[0040] When in use, first pass one end of the lining core 600 through the first support ring 401 and the second support ring 501 in sequence, and adjust the placement angle of the lining core 600 so that each placement groove 601 faces the corresponding pressure strip 403; then place the corresponding battery cell 700 in each placement groove 601 in sequence, and pass the end of the battery cell 700 through the first support ring 401 and the second support ring 501 in sequence, then turn on each telescopic cylinder 402 to drive the pressure strip 403 close to the battery cell 700, and keep the extended length of the output end of each telescopic cylinder 402 consistent, and squeeze each battery cell 700 through multiple pressure strips 403 evenly distributed in an annular shape to keep the collapsed battery cell 700 and the lining core 600 as a whole always coaxially placed with the second support ring 501, and each battery cell 700 is always evenly distributed in an annular shape around the central axis of the second support ring 501, so as to facilitate the subsequent spray coating mechanism to spray and coat them, thereby improving the uniformity of the coating spray;

The groove 4031 is coaxially placed with the pressure strip 403 and passes through both ends of the pressure strip 403. The cross-section of the groove 4031 along the axial direction is an isosceles triangle, and the symmetry planes of the two groove walls of the groove 4031 pass through the central axis of the first support ring 401. When the pressure strip 403 contacts the battery cell 700, the groove walls on both sides of the groove 4031 are tangent to the peripheral wall of the battery cell 700, which can improve the stability of the placement of the battery cell 700 and avoid the dislocation and sliding of the battery cells 700 and the liner core 600 as a whole between the multiple pressure strips 403 after folding.

[0043] Preferably, the two groove walls of the groove 4031 are smooth, which is convenient for pulling the battery cell 700 to move and reduces the wear on the surface of the battery cell 700.

[0044] The second support ring 501 is in the shape of a sealed shell with a hollow interior, and the ends of the injection heads 502 away from the central axis of the second support ring 501 are connected to delivery pumps 503, and the delivery pumps 503 are located inside the second support ring 501; the second support ring 501 stores coating paint or sol for coating, and the delivery pumps 503 facilitate pressurizing the coating paint or sol and spraying it out through the injection head 502.

[0045] Two injection rings are arranged in the second support ring 501 along the axial direction, and the orthographic projection of any injection head 502 in any injection ring along the axial direction of the second support ring 501 is located between two adjacent injection heads 502 in the other injection ring; the uniformity of the coating injection can be further improved by staggered arrangement of the injection heads 502 in the two injection rings.

[0046] The upper end of the second support ring 501 is connected to a feed pipe 504, which is connected to the inside of the second support ring 501; the feed pipe 504 is used to timely replenish the coating paint or sol in the second support ring 501. When necessary, the coating paint or sol in the second support ring 501 must always be kept full;

[0048] A pair of symmetrically placed connecting plates 404 are fixed on the outer peripheral wall of the first support ring 401, and the lower end surfaces of the connecting plates 404 are both in contact with the first support seat 200, and the connecting plates 404 and the first support seat 200 are threadedly connected by bolts 405; the connecting plates 404 and the first support seat 200 are threadedly connected by bolts 405, which is convenient for disassembly and assembly of the folding mechanism. Preferably, a variety of folding mechanisms of different specifications can be provided, and each folding mechanism has a different number of telescopic cylinders 402, so that a suitable folding mechanism can be selected according to the number of battery cells 700 to be coated.

The conical sleeve 800 can be made of elastic rubber, silicone, etc., and the battery cell 700 and the inner liner core 600 are further gathered and compacted by the conical sleeve 800 shell to prevent the battery cell 700 and the inner liner core 600 from loosening in the middle position between the first support ring 401 and the second support ring 501.
