At present, S-shaped metal honeycomb carriers with the advantages of durability, better turbulent flow formation and the like are used as basic structures. But the processing of the S-shaped metal honeycomb carrier is also complex and difficult. The winding device of the S-shaped metal honeycomb carrier on the market cannot meet the winding requirement of industrial large-diameter (150-800mm) metal carriers. Specifically, the winding device of the metal honeycomb carrier in the prior art has the following structure and working principle: the holding block is arranged on the outer side of the winding core rod in the circumferential direction, one end of the holding block is rotatably connected to the rotary table, and the other end of the holding block is a swinging end. When the winding operation is carried out, the winding core rod rotates and drives the strip to be wound on the winding core rod, and meanwhile, the holding block compresses the strip tightly. However, when the industrial metal carrier with a large diameter is wound, the winding radius is gradually increased, and the rotation driving force of the winding mandrel is also continuously increased, so that a plurality of problems occur: the belt material is torn, the core lattice is largely deformed and lost, the core body clearance is large, the efficiency is low, the qualified rate is low, and the production cost is high.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the application, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

As shown in fig. 1 and 2, the winding apparatus of the metal honeycomb carrier of the present embodiment includes a fixed tray 10, a rotary tray 30, and a cohesion block 40. Wherein, a winding core rod 20 is arranged on the fixed disc 10. The turntable 30 is rotatably provided below the fixed disk 10. The holding blocks 40 are movably arranged on the rotary disc 30 along the radial direction of the rotary disc 30, the holding blocks 40 are multiple, the holding blocks 40 are arranged at intervals along the circumferential direction of the winding core rod 20, and the holding blocks 40 surround the outer side of the fixed disc 10.

By applying the technical solution of the present embodiment, when performing winding work, the winding mandrel 20 is disposed on the fixed disk 10 and the winding mandrel 20 does not rotate, the turntable 30 rotates, and the holding block 40 moves towards the center of the turntable 30, so that the strip is wound on the winding mandrel 20. In the above-mentioned structure, the effort of exerting on winding plug 20 is less when carrying out winding work to prevent that the strip from tearing, the condition that the core check warp in a large number and go out to lose takes place, thereby better be applicable to major diameter industry metal honeycomb carrier. Therefore, the technical scheme of the embodiment solves the problem that the winding equipment of the metal honeycomb carrier in the prior art cannot be suitable for winding the large-diameter industrial metal honeycomb carrier.

As shown in fig. 1 and 2, in the solution of the present embodiment, the clasping block 40 includes a clasping section 41 and a stroking tooth 42. Wherein, the inner surface of the cohesion section 41 is a cambered surface. Both end surfaces of the clasping section 41 along the circumferential direction of the fixed disk 10 are provided with material smoothing teeth 42. The surface of the stripping teeth 42 facing the winding mandrel 20 is bent outward relative to the inner surface of the looping section 41, wherein the stripping teeth 42 on the opposite surface of adjacent looping sections 41 are offset.

Specifically, as can be seen from fig. 1, the two sides of each embracing block 40 in the circumferential direction are provided with the above-mentioned stripping teeth 42. The stripping teeth 42 on the opposite surfaces of adjacent looping sections 41 are offset (not shown), i.e. the stripping teeth 42 of adjacent looping blocks 40 can be inserted into each other when the adjacent looping blocks 40 are moved inward. Further, when the tooth ends of the stroking teeth 42 of the adjacent holding blocks 40 are in contact, a closed space is formed among the holding blocks 40. Since the surface of the stripping teeth 42 facing the winding mandrel 20 is bent outward relative to the inner surface of the looping section 41, the inner surface of the looping section 41 does not yet press the strip. That is, the structure enables the belt materials to be sealed into a closed space in advance when the belt materials are not compacted, prevents the belt materials from being clamped when the belt materials continue to be clasped, and reduces the friction force between the belt materials when the belt materials are wound.

Therefore, in the embodiment, the material smoothing teeth on the cohesive block are beneficial to winding the wound belt material into a closed cavity in advance, so that the possibility of material clamping during cohesive is reduced, and the friction force between the belt materials in the winding process is reduced.

As shown in fig. 1 and 2, in the solution of the present embodiment, when the plurality of clasping blocks 40 are moved until the roots of the fingers 42 of adjacent clasping blocks 40 contact, the inner surfaces of the clasping sections 41 are rounded. Specifically, after the tooth ends of the stroking teeth 42 of adjacent ones of the clasping blocks 40 are contacted, the clasping blocks 40 continue to move inward. Until the roots of the stripping teeth 42 of adjacent holding blocks 40 are in contact, the inner surfaces of the holding blocks 40, that is, the surfaces of the holding blocks 40 facing the winding mandrel 20, together form a complete circle, thereby completing the holding of the strip.

As shown in fig. 1, in the solution of the present embodiment, the arc of the inner surface of the clasping section 41 is 45 degrees. In particular, the inner surface of the looping section 41 refers to the surface of the looping section 41 facing the winding mandrel 20. Of course, the arc may be adaptively adjusted by those skilled in the art.

As shown in fig. 1, in the embodiment of the present invention, the surface of the stripping tooth 42 facing the winding core rod 20 is an arc surface. Preferably, the arc of the surface of the stripping teeth 42 facing the winding mandrel 20 is in the range of 15 to 45 degrees. Of course, the arc may be adaptively adjusted by those skilled in the art.

As shown in fig. 1, in the solution of the present embodiment, the intersection of the surface of the stripping tooth 42 facing the winding core rod 20 and the inner surface of the looping section 41 forms an angle in the range of 15 to 40 degrees. Specifically, the inner surfaces of the fingers 42 are inclined outward relative to the inner surface of the clasping section 41, so that the structure is such that when the tips of the fingers 42 contact each other, the inner surface of the clasping section 41 is not yet fully enclosed, thereby enclosing the strap in a closed space in advance before clasping.

As shown in fig. 1 and 2, in the present embodiment, there are a plurality of the raking teeth 42, and the plurality of the raking teeth 42 are provided at intervals on the end surface of the clasping section 41 in the circumferential direction of the fixed disk 10. Specifically, in the present embodiment, a plurality of stripping teeth 42 are provided on each side of the looping section 41, and the plurality of stripping teeth 42 are provided in a manner that satisfies the following condition: on two opposite sides of two adjacent embracing blocks 40, a plurality of stripping teeth 42 are arranged in a staggered manner. As shown in fig. 2, the fingers 42 of one block 40 are then inserted into the spaces between the fingers 42 of an adjacent block 40 as the blocks 40 move inward.

As shown in fig. 1 and 2, in the solution of the present embodiment, there are four embracing blocks 40, and the four embracing blocks 40 are uniformly arranged along the circumferential direction. Specifically, in the present embodiment, the clasping block 40 is composed of four pieces, and four pieces of the same power are respectively pushed from four equal angles to the center of the circle, so as to meet the requirement of the large-diameter metal honeycomb carrier on the clasping power. The core grid gap caused by the unbalanced stress due to insufficient power is overcome.

The industrial carrier is large and high in diameter, and when the industrial carrier is wound and clasped, the tension inside the core body is large, and the clasping force needs to be large. The four embracing blocks are synchronously pushed and rotated under the control of a computer driven by four motors respectively, so that sufficient power is provided for embracing the four embracing blocks, and the core body is prevented from generating gaps. And the overlapped strip materials are put into the cavity, and the opening is relatively large, so that the strip materials can smoothly enter the cavity without large resistance, and the deformation and loss of core grids at the periphery of the core rod are reduced. Four embracing blocks are adopted to propel the embracing, the embracing power is sufficient, the acting force is divided into four blocks to equally point to the center, the S shape of the wound core body is smooth, no gap exists, and the core lattices around the central hole are not lost.

In this embodiment, the winding apparatus further includes a first driving mechanism, a second driving mechanism, and a control device. Wherein, the first driving mechanism is connected with the rotating disc 30 and drives the rotating disc 30 to rotate. The second driving mechanism is connected with the clasping block 40 and drives the clasping block 40 to move. The control device is connected with the first driving mechanism and the second driving mechanism, and controls the second driving mechanism to drive the holding blocks 40 to move while controlling the first driving mechanism to drive the turntable 30 to rotate, and the second driving mechanism drives the holding blocks 40 to move towards the fixed disk 10 at the same speed, so that the strip winding work is completed.

The rotary table rotates, and the cohesion block rotates along with the rotary table, so that the belt material is driven to wind; meanwhile, the holding block is pushed towards the center of the fixed disc along a straight line. Rotation is coordinated with propulsion.

The material smoothing teeth on the cohesion block are beneficial to winding the wound belt materials into a closed cavity in advance, so that the possibility of material clamping during cohesion is reduced, and the friction force between the belt materials in the winding process is reduced.

The clasping block consists of four pieces, and four pieces of same power are respectively pushed to the circle center from four equal angles, so that the requirement of the large-diameter metal honeycomb carrier on the clasping power is met.
