Description

Technical Field

[0001] This utility model relates to the field of mold adjustment equipment technology, and in particular to a mold adjustment device for rotating the head of a wire mesh equipment. Background Technology

[0002] During the operation of the rotating head mesh equipment, the thickness of the mesh and the fineness of the mesh lines are mainly controlled by the forming openings of the inner and outer molds and the gap between the inner and outer molds. The forming openings of the inner and outer molds are formed by the combination of the groove opening on the outer circumference of the inner mold and the groove opening on the inner circumference of the annular outer mold. The groove openings can be arc-shaped, semi-circular, square, prismatic, etc. The gap between the inner and outer molds is generally relatively small.

[0003] In existing technologies, molds may develop dimensional errors during processing, storage, and transportation. Furthermore, wear and tear during continuous use can affect mold precision. Since the inner mold of the rotating head in wire mesh production equipment is mounted on a rotating mandrel, while the outer mold is mounted on the rotating gear of the head, changes in the gap between the inner and outer molds may occur during their relative counter-rotation. In some cases, the inner and outer molds may even come into contact on one side, causing rotational jamming. Generally, this requires removing the mold for reprocessing, which not only reduces the forming quality of the wire mesh and delays processing, but also carries the risk of mold failure in severe cases. Utility Model Content

[0004] This application provides a mold adjustment device for a rotating head of a wire mesh equipment. It can directly fine-tune the position of the outer mold on the rotating head of the wire mesh equipment, thereby flexibly adjusting the gap between the inner mold and the outer mold. This ensures the forming quality of the wire mesh and avoids the need to disassemble the mold for reprocessing, thus ensuring the forming efficiency of the wire mesh.

[0005] This application provides a mold adjustment device for a rotating head of a wire mesh equipment, used to adjust the position of the outer mold relative to the inner mold on the rotating head of the wire mesh equipment. The rotating head includes a rotating mandrel and a rotating gear extending coaxially. The rotating gear is fitted onto the rotating mandrel with a clearance fit and rotates in the opposite direction to the rotating mandrel. The mold adjustment device includes an inner mold, an outer mold, a positioning adjustment ring, and adjustment bolts. The inner mold is coaxially mounted on the rotating mandrel. The outer mold is annular and connected to the rotating gear by connecting bolts evenly distributed circumferentially. The positioning adjustment ring is distributed around the outer ring of the outer mold and fixedly connected to the rotating gear. The inner mold, the outer mold, and the positioning adjustment ring all extend in the same direction axially from the rotating mandrel. Multiple adjustment bolts are evenly installed circumferentially on the positioning adjustment ring, with the bolt head abutting against the outer periphery of the outer mold and the head of the adjustment bolt located outside the positioning adjustment ring.

[0006] In one possible implementation, the rotating mandrel includes a rod body and a mandrel, wherein the mandrel is coaxially connected to the outer end of the rod body and the diameter of the mandrel is smaller than the diameter of the rod body. The inner mold is sleeved on the mandrel and the inner mold is fixedly connected to the rod body by circumferentially distributed fastening screws.

[0007] In one possible implementation, the mandrel portion and the rod portion are an integral structure, or the mandrel portion is connected to the rod portion by welding.

[0008] In one possible implementation, the mold adjustment device further includes a feeler gauge for rapidly rotating the adjusting bolt or for detecting the gap between the inner mold and the outer mold.

[0009] In one possible implementation, a fastening nut is also threaded onto the screw of the adjusting bolt, and the fastening nuts are located on both sides of the positioning adjusting ring.

[0010] Beneficial effects: Compared with the prior art, the mold adjustment device for the rotating head of the wire mesh equipment provided in this application can directly finely adjust the position of the outer mold relative to the inner mold on the rotating head of the wire mesh equipment through the cooperation of the positioning adjustment ring and the adjustment bolt, so as to ensure that the outer mold and the inner mold can maintain a suitable discharge gap, thereby ensuring the forming quality of the wire mesh, while avoiding the need to disassemble the mold for reprocessing, and ensuring the forming efficiency of the wire mesh.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0017] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] refer to Figures 1 to 4This application provides a mold adjustment device for a rotating head of a wire mesh equipment, used to adjust the position of the outer mold relative to the inner mold on the rotating head of the wire mesh equipment. The rotating head 100 of the wire mesh equipment includes a rotating mandrel (not shown in the figure) extending coaxially and a rotating gear 50. The rotating gear 50 is fitted onto the rotating mandrel in a clearance fit and rotates in the opposite direction to the rotating mandrel. That is, there is a clearance fit positional relationship and an opposite rotational movement relationship between the rotating gear 50 and the rotating mandrel. Since the rotating gear 50 and the rotating mandrel rotate in opposite directions and are installed on two different devices, the mold (including the inner mold and the outer mold) will have dimensional deviations during processing, storage, transportation, and long-term use, which will affect the accuracy of the mold.

[0020] The mold adjustment device includes an inner mold 10, an outer mold 20, a positioning adjustment ring 30, and an adjustment bolt 40. Under normal circumstances, there is a forming gap α between the inner mold 10 and the outer mold 20, and the outer circumference of the inner mold 10 and the inner circumference of the outer mold 20 are respectively provided with forming grooves β. The inner mold 10 is coaxially mounted on the rotating mandrel. The outer mold 20 is annular and connected to the rotating gear 50 by connecting bolts 21 evenly distributed in the circumferential direction. The positioning adjustment ring 30 is distributed on the outer ring of the outer mold 20 and fixedly connected to the rotating gear 50. The inner mold 10, the outer mold 20, and the positioning adjustment ring 30 all extend in the same direction along the axial direction of the rotating mandrel. Multiple adjusting bolts 40 are present, and these multiple adjusting bolts 40 are evenly distributed in the circumferential direction. The adjusting bolts 40 are evenly installed on the positioning adjustment ring 30, and the screw 41 of the adjusting bolt 40 abuts against the outer periphery of the outer mold 20. At the same time, the head 42 of the adjusting bolt 40 is located on the outside of the positioning adjustment ring 30. In this way, when workers find that the thickness and thickness of the mesh material change significantly during the production process, or find that the inner and outer molds are stuck, they can stop the machine and observe the gap between the inner mold 10 and the outer mold 20, or judge the gap between the inner mold 10 and the outer mold 20 by the thickness and thickness of the mesh material.

[0021] For example, if the mesh material is found to be thicker on the left and thinner on the right, it indicates that the outer mold 20 has shifted as a whole. The gap between the inner mold 10 and the outer mold 20 is larger on the left and smaller on the right. Adjustments can then be made directly on the rotating head 100 of the mesh material processing equipment without removing the molds. The adjustment process is roughly as follows: First, loosen the connecting bolt 21; Then fine-tune the adjusting bolt 40 on the right side. Rotate the adjusting bolt 40 on the right side to move it slightly outward. The closer to the right side, the greater the displacement of the adjusting bolt 40, but the maximum axial displacement generally will not exceed 0.2mm. Then, fine-tune the left adjusting bolt 40 by rotating it to move it slightly inward, that is, slightly towards the side closer to the rotating mandrel. The closer to the left, the greater the displacement of the adjusting bolt 40, thereby pushing the outer mold 20 to move slightly to the right. Finally, when it is determined by visual inspection or by using a feeler gauge that the gaps on the left and right sides are not significantly different or are equal, first tighten the connecting bolt 21, and then tighten the adjusting bolt 40 on the right side.

[0022] When the outer mold 20 deforms, for example, the left side of the mesh is thicker while the right side still has a normal-sized gap, then only the left adjusting bolt 40 needs to be finely adjusted. That is: first loosen the connecting bolt 21, then finely adjust the left adjusting bolt 40 by rotating the left adjusting bolt 40 to move it slightly inward, that is, slightly towards the side closer to the rotating mandrel. The maximum axial displacement generally will not exceed 0.2mm. Compress the gap on the left side of the inner and outer molds. When it is judged by the naked eye or by a feeler gauge that the gaps on the left and right sides are not much different or equal, tighten the connecting bolt 21.

[0023] It should be noted that the connecting bolt 21 has a threaded engagement with both the outer mold 20 and the rotating gear 50. When the connecting bolt 21 is loosened, there is still a certain clearance engagement between the connecting bolt 21, the outer mold 20, and the rotating gear 50. Therefore, when fine-tuning the adjusting bolt 40, it is not necessary to remove the connecting bolt 21 within the maximum adjustment stroke range of ±0.2mm. The relative position of the outer mold 20 can still be adjusted by rotating the adjusting bolt 40.

[0024] In addition, the positioning adjustment ring 30 is provided with a corresponding threaded through hole 301 that mates with the adjustment bolt 40.

[0025] In a preferred embodiment, the mold adjustment device further includes a feeler gauge, which is used to quickly rotate the adjusting bolt 40 or to detect the gap between the inner mold 10 and the outer mold 20. The feeler gauge being used to quickly rotate the adjusting bolt 40 means that, for locations with larger gaps, a feeler gauge of appropriate thickness can be inserted into the gap first, and then the adjusting bolt 40 can be quickly rotated until it is precisely inserted into the gap between the inner and outer molds, indicating that the adjustment is in place, thus improving adjustment efficiency. The feeler gauge being used to detect the gap between the inner mold 10 and the outer mold 20 means that, when the mesh thickness changes, the feeler gauge can be used to detect the gap between the inner mold 10 and the outer mold 20, thereby determining how to rotate the adjusting bolt 40. It can also be used to check whether the adjustment is satisfactory after completion.

[0026] In one embodiment, the rotating mandrel includes a rod body and a mandrel, wherein the mandrel is coaxially connected to the outer end of the rod body and the diameter of the mandrel is smaller than the diameter of the rod body. The inner mold 10 is sleeved on the mandrel and is fixedly connected to the rod body by circumferentially distributed fastening screws 11. The sleeve relationship between the inner mold 10 and the mandrel, such as an interference fit or a transition fit, can form a radial limiting effect to prevent radial displacement of the inner mold 10. At the same time, the fastening screws 11 fix the inner mold 10 to the rod body, which can form an axial limiting effect to prevent axial movement inside. Ultimately, the inner mold 10 can be well fixed, and only the outer mold 20 needs to be adjusted during the gap adjustment process.

[0027] In one embodiment, the mandrel portion and the rod portion are an integral structure, which has high structural strength and is convenient to use. Alternatively, the mandrel portion is welded to the rod portion, which can be easily manufactured separately through a split processing method.

[0028] The die adjustment device for the rotating head of the wire mesh equipment provided in this application directly adjusts the relative position of the outer die 20 on the rotating head of the wire mesh equipment. Although the outer die 20 is fixed axially by the connecting bolt 21 and radially by the adjusting bolt 40, with the increase of use time, the adjusting bolt 40 may still loosen due to slight vibration of the machine, which may again affect the positional accuracy of the outer die 20. Therefore, in one embodiment, a fastening nut 43 is also threaded onto the screw 41 of the adjusting bolt 40. At the same time, the fastening nut 43 is located on both sides of the positioning adjustment ring 30. Thus, after the adjusting bolt 40 is rotated into place, the fastening nut 43 can be rotated to make it fit tightly against both sides of the positioning adjustment ring 30, which can further fix the adjusting bolt 40 and strengthen the locking effect of the adjusting bolt 40 on the outer die 20, thereby further ensuring the positional accuracy and stability of the outer die 20.

[0029] It should be noted that although the mold adjustment device provided in this application has a very simple structure, it is highly practical and especially suitable for manual adjustment by operators of small and medium-sized enterprises. It is low in cost, has little impact on work efficiency, and is not likely to damage the mold.

[0030] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
