Description

Technical Field

[0001] The utility model belongs to the technical field of extrusion equipment and relates to wire extrusion auxiliary equipment. Background Art

[0002] In the field of 3D printing filament production, the filament needs to be cooled during the extrusion process. This means that the extruded filament must be manually connected to the cooling equipment. While manual pulling of single-strand filament is acceptable, most companies are currently opting for multi-strand filament extrusion to improve efficiency. This can easily lead to interference between the extruders, and the high temperature of uncooled filament. Manual removal of this interference often results in uneven force, which negatively impacts both filament quality and production efficiency. Currently, there is no automated wire-pulling equipment available for filament extrusion. Utility Model Content

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The wire extrusion auxiliary equipment described in the present invention uses an extruder head to extrude wire. Since the hardness of the wire is not high before cooling, the wire will droop to the cutting assembly when it is not pulled. The wire diameter detection device is used to detect the diameter of the wire extruded from the extruder head. When the wire diameter meets the standard, the cutting assembly is used to perform a cutting operation, and the wire that does not meet the standard at the front end is cut off and falls into the collection box.

The present invention uses a wire diameter detection device to detect the wire diameter, which avoids defects caused by human eye errors, effectively improves the qualified rate of the extruded wire, and improves the quality of the extruded wire while reducing labor costs. Substandard wires are removed by cutting components, and the substandard wires are collected using a collection box. This not only achieves the removal of substandard wires, prevents substandard wires from entering the final product, and improves the wire qualification rate, but also collects the removed wires for later secondary use. Moreover, the automatic removal by the cutting component avoids the impact of manual removal on production efficiency. After removing substandard wires, the utility model uses a wire balance wheel to preliminarily pick up and carry qualified wires to the preset position required for the next step. This design can conveniently pick up qualified wires after removing substandard wires and carry them to the preset position for subsequent processes, reducing human pulling, avoiding the tediousness of manual operation, and improving production efficiency. The utility model has a compact structure, a wide range of applications, and high production efficiency.

[0019] Furthermore, the utility model divides a stream of material into several strands by setting a diversion channel insert, so that one extruder head can extrude several strands of wire at a time. Compared with the existing single-strand extrusion production line, it greatly improves the production efficiency from the source and reduces the production cost.

[0031] In the present invention, the extrusion direction of the wire material in the extrusion equipment is taken as the front.

[0032] like Figure 1 、 Figure 2 and Figure 4 As shown, the wire extrusion auxiliary device of the present invention includes: an extruder head 10, a wire diameter detection device 20 and a wire bonding device 40; the wire diameter detection device 20 is used to detect the diameter of the wire extruded from the extruder head 10;

[0033] The wire-laying device 40 includes a wire collection box 41, a wire-laying balance wheel 45, a balance wheel driving device 46 and a cutting assembly; the wire collection box 41 is located below the extrusion port of the extruder head 10, and a cutting assembly is arranged between the wire collection box 41 and the extrusion port of the extruder head 10, and the cutting assembly is used to cut the wire that is extruded from the extrusion port of the extruder head 10 and droops and has a diameter that does not meet the standard; the lower end of the wire-laying balance wheel 45 is connected to the output end of the balance wheel driving device 46, and a guide groove 48 is arranged on the upper end face of the wire-laying balance wheel 45, and the guide groove 48 is used to carry the wire extruded from the extrusion port of the extruder head 10 after the cutting assembly completes the cutting operation and transport the wire to a preset position.

[0034] The working principle of the wire extrusion auxiliary equipment is as follows: the wire is extruded using the extruder head 10. Usually, the diameter of the wire extruded at the beginning does not meet the standard, that is, the diameter of the wire is uneven (sometimes thick, sometimes thin) and does not meet the diameter requirements. Therefore, the wire extruded in the early stage is not pulled and cooled, but is cut off as waste. Since the temperature of the extruded wire is very high and the hardness is not high before cooling, it will fall vertically downward due to gravity when it is not pulled. Therefore, the wire extruded from the extrusion port of the extruder head 10 will sag. The wire diameter detection device 20 is used to detect the diameter of the wire extruded from the extruder head 10. When the diameter of the wire meets the standard, the cutting assembly is used to perform a cutting operation, and the wire that does not meet the standard at the front end is cut off and falls into the collection box 41. The wire that does not meet the standard can be collected and reused, saving production costs. The balance wheel driving device 46 is used to drive the wire-taking balance wheel 45 to rotate in the longitudinal plane. When the cutting operation of the cutting assembly is completed, the balance wheel driving device 46 is used to drive the wire-taking balance wheel 45 to rotate in the longitudinal plane, so that the qualified wire extruded by the extruder head 10 is loaded on the guide groove 48 of the wire-taking balance wheel 45 and lifted to a preset position at the same height as the subsequent cooling device to enter the subsequent cooling process.

[0035] The present invention adopts a wire diameter detection device 20 to detect the diameter of the wire, avoiding the defects caused by the error of the human eye, effectively improving the qualified rate of the extruded wire, and improving the quality of the extruded wire while reducing the labor cost. The substandard wires are cut off by the cutting assembly, and the substandard wires are collected by the collection box 41. Not only the substandard wires are cut off, avoiding the substandard wires from entering the final product and affecting the qualified rate of the product, but also the cut wires are collected for easy secondary use in the later stage. Moreover, the automatic cutting method of the cutting assembly avoids the impact of manual cutting on production efficiency. After cutting off the substandard wires, the present invention performs preliminary picking up of the qualified wires by the wire balance wheel 45, so that it reaches a position flush with the next cooling device. This design can conveniently pick up the qualified wires after cutting off the substandard wires and carry them to the preset position for subsequent operations, avoiding the tedious manual operation and improving efficiency.

[0036] When in use, the extruder head 10 is assembled at the front end of the extruder. Figure 3As shown, in a specific embodiment of the present invention, the extruder head 10 includes a main channel insert 11, a main channel fixing block 12, a branch channel insert 13, a branch channel fixing block 14 and an extrusion insert 15. The main channel fixing block 12 is arranged on the periphery of the main channel insert 11 and the branch channel insert 13, and the main channel insert 11 and the branch channel insert are fixedly connected together through the main channel fixing block 12; thus, the main channel fixing block 12 defines the position of the main channel insert 11 and the branch channel insert 13, and the fixed connection between the two can be ensured without bolts. The branch channel insert 13 and the extrusion insert 15 are fixed together through the branch channel fixing block 14, and the position of the branch channel insert 13 and the extrusion insert 15 is defined by the branch channel fixing block 14, ensuring the effective connection between the flow channel of the branch channel insert 13 and the flow channel of the extrusion insert 15, ensuring that the material flow of the wire is evenly distributed and does not interfere during the extrusion process.

[0037] A main channel is provided in the main channel insert 11, and a plurality of first branch channels are provided in the branch channel insert 13, and the outlet of the main channel is connected with the inlet of all the first branch channels; the number of the extrusion inserts 15 is consistent with the number of the first branch channels, and each extrusion insert 15 is provided with an extrusion channel, and the outlet of the first branch channel is connected with the inlet of the extrusion channel in a one-to-one correspondence.

[0038] The extruder head 10 used in the present invention includes a plurality of extrusion channels. Therefore, multiple strands of wire can be extruded simultaneously through one extruder head, thereby effectively improving production efficiency while reducing equipment costs.

[0039] In a preferred embodiment, four first branch channels are provided in the branch channel insert 13, four extrusion inserts 15 are provided, and each extrusion insert 15 is provided with an extrusion channel, and the outlets of the four first branch channels in the branch channel insert are connected to the inlets of the four extrusion channels in a one-to-one correspondence.

[0040] As a further optimization solution, the axes of the four extrusion channels are parallel to each other and are distributed in a trapezoidal shape, so that the distance between the four wire strands extruded by the four extrusion inserts 15 is large enough to avoid adhesion and interference of the four wire strands after extrusion.

[0041] To avoid adhesion problems that may result from direct contact between the runner insert 13 and the extrusion insert 15, in one embodiment, a second runner is provided within the runner fixing block 14. The number of the second runners is the same as the number of the first runners, and each first runner is connected to the corresponding extrusion runner via a second runner. In one embodiment, the axes of the four second runners are parallel to each other and arranged in a trapezoidal pattern. The axes of the four second runners are coaxial with the axes of the four extrusion runners, and the axes of the extrusion runners are parallel to the axes of the main runner within the main runner insert 11.

[0042] In the present invention, the wire diameter detection device 20 is located in the upper front of the extruder head 10. The position of the wire diameter detection device 20 can be adjusted according to the size of the extruded wire and the space requirements of the factory. In a specific embodiment of the present invention, the wire diameter detection device 20 is a visual diameter measuring component supported and fixed by a bracket. The visual diameter measuring component is used to detect the diameter of the wire extruded from the extruder head 10.

[0043] The visual diameter measurement component's detection standards and accuracy range can be customized based on actual needs. The model number for this component is MV-CE100-31GM. Once the visual diameter measurement component detects that the wire extruded by the rear extruder head 10 meets the required diameter, the wire-tapping device 40 removes the waste material (i.e., the wire whose front end diameter does not meet the required diameter). Meeting the required wire diameter means that the measured wire diameters within a preset time period are all within a preset wire diameter range.

[0044] The use of visual diameter measuring components to detect wire diameter is a non-contact measurement method. It can measure the diameters of multiple wires at the same time. It is more accurate and does not cause any damage to the wires themselves. It effectively improves the product qualification rate and avoids defects caused by human eye errors. While reducing labor costs, it also improves the quality of extruded wire.

[0045] In order to improve the detection accuracy of the visual caliper, the present invention further includes an illumination device 30. The light from the illumination device 30 is directed to the extrusion port area of ​​the extruder head 10, providing sufficient light for the visual caliper, thereby ensuring the accuracy of the detection results of the visual caliper. In a specific embodiment of the present invention, the illumination device 30 is a circular ring structure, the lens of the visual caliper is coaxial with the circular ring structure, and the diameter of the lens of the visual caliper is no larger than the inner diameter of the circular ring structure.

[0046] The bracket of the utility model is made of high-temperature resistant and rust-proof materials, or is coated with high-temperature resistant, anti-oxidation and anti-rust coatings to avoid the influence of high temperature on the bracket.

[0047] In a specific embodiment of the present invention, the cutting assembly includes a tool 43, a tool groove 42 cooperating with the tool 43, and a tool driving device 44. The tool driving device 44 is used to drive the tool 43 to insert into the tool groove 42 to cut off wires that do not meet the diameter standards, and the wires that do not meet the standards fall into the wire collection box 41.

[0048] Because the wire extruded by the extruder head 10 has a very high temperature and low hardness before cooling, it will fall vertically downward due to gravity. Therefore, the collection box 41, the knife groove 42 and the tool 43 are set below the extrusion port area of ​​the extruder head 10. Before the wire directly meets the standard, the wire hangs down to the gap between the knife groove 42 and the tool 43. When the wire directly meets the standard, the tool 43 can be used to cut off the wire that does not meet the standard and drop it into the collection box 41 for collection.

[0049] In a specific embodiment, the tool drive 44 can be a pneumatic cylinder, such as a CTSI-32×25-H model, and is located below the balance drive 46. The balance drive 46 can be a pneumatic cylinder, such as a MSZB 20A-A90L rotary cylinder. The balance drive 46 is mounted above the tool drive 44 and maintains consistent drive. That is, when the tool drive is activated to cut the wire, the balance drive is activated to connect the wire to the next cooling stage.

[0050] The cutter 43 can be replaced according to the strength of the wire to ensure smooth cutting. The utility model does not limit the size and shape of the junction box 41, and can be designed with high temperature and corrosion resistant materials to avoid damage to the junction box caused by the initial substandard wire being too hot.

[0051] The tool drive device 44 is controlled by the feedback command of the wire diameter detection device 20. When the four strands of extruded wire meet the standards, the wire diameter detection device 20 transmits a signal to the tool drive device 44, so that the tool drive device 44 controls the tool 43 to cut the four strands of extruded wire at the same time. This method avoids the impact of manual cutting on production efficiency.

[0052] The wire-laying device 40 may further include a wire-laying bracket 47 , on which the wire collection box 31 , the cutting assembly, the wire-laying balance wheel 45 and the balance wheel driving device 46 are all disposed.

[0053] The above detailed description is a specific description of a feasible embodiment of the present invention. The embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not deviate from the present invention should be included in the patent scope of this case.
