Description

Technical Field

[0001] The utility model relates to the field of coating machine rollers, in particular to a multifunctional coating machine roller. Background Art

[0002] The coating machine is mainly used for surface coating production of cloth, film, paper, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and cuts it into sheets or reels after drying. It uses a special multi-functional coating head and can realize various forms of surface coating. The rewinding and unwinding of the coating machine are equipped with full-speed automatic film splicing mechanism and PLC program tension closed-loop automatic control.

[0003] In order for a coating machine to process fabric, the fabric needs to be moved in the machine. Most of the time, rollers at both ends are used for retraction and extension. The roller is a common and simple load-bearing device. The overall structure is a long cylindrical part. It is used in equipment and mechanisms with winding requirements. Since the width of the fabric processed by the coating machine may be different, the traditional use of rollers with fixed sizes may cause the fabric movement path to deviate due to a certain step in the operation when collecting the fabric. Then, the ends of the fabric rolls collected on the rollers and reels will be uneven. To deal with this situation, cutting equipment can be used to cut off the uneven parts at both ends, but this will undoubtedly increase labor and material costs and cause waste.

[0004] A multifunctional coater roller is provided for this purpose. Utility Model Content

[0005] 1. Technical Problems Solved

[0006] The technical problem to be solved by the utility model is that the roller in the existing coating machine is simple and factors such as length cannot be adjusted. When the technical parameters of the processed fabric change, it cannot effectively adapt to and achieve good clamping of the fabric roll.

[0007] 2. Technical Solution

[0008] In order to solve the above technical problems, the technical solution provided by the present invention is: a multifunctional coating machine roller, comprising a machine base, wherein both ends of the machine base are respectively connected with a spreading end and a winding end.

[0009] The machine base is located at the bottom of the unfolding end and the winding end, and is rotatably connected with a screw, and one end of the screw is commonly connected with a chain groove chain transmission mechanism, and the external thread structures at both ends of the screw are arranged in opposite directions. The machine base is located on one side of the winding end and is connected with a No. 1 motor that cooperates with the screw, and the two ends of the screw are connected with a driving block with an internal thread structure. The lower ends of the machine base are connected with a limiting slide, and the bottom of the driving block is downwardly connected with a sliding column extending into the limiting slide, and a bracket one is connected above the driving block, and a roller bearing mechanism is rotatably connected between the brackets one.

[0010] Furthermore, the roller bearing mechanism includes a support shaft, which is rotatably connected inside the top of the bracket one, and a No. 2 motor that cooperates with the support shaft is connected to the side above the winding end. The support shaft is connected to a bracket two at one end away from the bracket one, and a clamping mechanism is connected to the bracket two.

[0011] Furthermore, the clamping mechanism includes a bolt, which is rotatably connected inside the second bracket, and the bolt is connected to a support rod at one end away from the support shaft. The two ends of the second bracket are rotatably connected to clamping rods with a V-shaped structure, and a driving rod is rotatably connected between the middle position of the clamping rod and one end of the support rod, and the clamping rod is connected to an interference end at one end away from the second bracket.

[0012] Furthermore, a handle is connected to one end of the bolt away from the support rod, and the upper and lower ends of the handle protrude from the upper and lower sides of the bracket 2. In this way, in the narrow space formed by the bracket 2 and other components, the bolt can be rotated by simply touching the top of the handle with a finger and turning it.

[0013] Furthermore, the second bracket is connected to a ring-shaped abutment plate near the abutment end, which is mainly used to provide a limiting effect on the winding path for the cloth collected on the roller bearing mechanism on the winding end side, so as to avoid uneven edges of the cloth roll after winding.

[0014] 3. Beneficial Effects

[0015] The advantages of the present invention over the prior art are that the versatility of the roller device is reflected in the matching support for the width of the fabric and the clamping of rolls of different specifications for the wound fabric. First, it drives the brackets at both ends of the roller to freely approach and move away from each other through the rotation of the screw, thereby supporting the roll while adapting to different roll lengths. Secondly, it transforms the traditional cylindrical roller with a simple structure into two groups of brackets with clamping mechanisms and abating plates. By rotating the bolts, the width of the clamping mechanism is adjusted to adapt to rolls of different diameters. It has a high degree of adaptability and selectivity.

DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] Combined with attachment Figure 1-3 The present invention also provides a plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings of the plurality of couplings

[0025] The two ends of the coating machine, namely the unwinding end 2 and the winding end 3, are originally supported by rollers, which are set as two brackets 10, and a screw 4 with symmetrical threads is set below it. The machine base 1 is a part of the body of the coating machine itself, and serves as the supporting body of the roller device. A No. 1 motor 5 is installed on one side of the machine base 1 to cooperate with the screw 4 at the winding end 3 to provide power support for the rotation of the screw 4. The common chain groove chain transmission mechanism 6 between this screw 4 and the screw 4 at the unwinding end 2 matches each other and maintains synchronous rotation. When the two screws 4 rotate, the slide column 8 extending into the limiting slide groove 9 under the driving block 7 drives the two brackets 10 to move away from or approach each other under the provided limiting conditions. On the one hand, the reel for winding the fabric is clamped from both ends. On the other hand, due to the moving effect provided by the screw 4, the roller device can clamp a reel of any length within a certain range, so as to meet the processing requirements of fabrics of different widths on the coating machine equipment.

[0026] Example 2

[0027] Combined with attachment Figure 1-5 , the roller bearing mechanism includes a support shaft 11, the support shaft 11 is located in the top of the bracket 10 and is rotatably connected. A second motor 12 is connected to the upper side of the winding end 3 and matches the support shaft 11. The support shaft 11 is connected to a bracket 2 13 at one end away from the bracket 10. A clamping mechanism is connected to the bracket 2 13. The clamping mechanism includes a bolt 15, and the bolt 15 is located in the bracket 2 13 and is rotatably connected. The bolt 15 is connected to a handle 16 at one end away from the support rod 17. The upper and lower ends of the handle 16 protrude from the upper and lower sides of the bracket 2 13. In this way, in the narrow space composed of the bracket 2 13 and other components, only a finger touches the handle. By toggling the top of the handle 16, the bolt 15 can be rotated. The bolt 15 is connected to a support rod 17 at one end away from the support shaft 11, and the two ends of the bracket 2 13 are rotatably connected to a clamping rod 19 with a V-shaped structure. A driving rod 18 is rotatably connected between the middle position of the clamping rod 19 and one end of the support rod 17. The clamping rod 19 is connected to a resistance end 20 at one end away from the bracket 2 13, and the side of the bracket 2 13 close to the resistance end 20 is connected to a resisting disk 14 with a ring structure. This is mainly for providing a limiting effect on the winding path for the cloth collected on the roller bearing mechanism on the side of the winding end 3, so as to avoid uneven edges of the cloth roll after winding.

[0028] Through two unconnected brackets 2 13, fixed on two brackets 10, instead of the traditional simple cylindrical roller, although the bracket 2 13 is not a cylindrical structure that can match the circular roll, the bracket 2 13 is provided with a clamping mechanism that can be tightened from one end of the circular roll. By rotating the bolt 15, the support rod 17 at the end and the clamping rod 19 can be moved. By rotating the driving rod 18 connected to the clamping rod 19 and the support rod 17, the clamping rod 19 connected to the bracket 2 13 at one end is rotated. The two clamping rods 19 are rotated with the bolt 15 as the center. They are symmetrically arranged and each has a V-shaped structure. The sharp corners of the bottom end of the V are close to each other. The other end connected to the bracket 13 is provided with a contact end 20, and a suitable material such as a rubber block can be used here. When the contact ends 20 are away from each other, they slowly approach the inner wall of the reel and tighten it in a stretched manner. This clamping method can, on the one hand, support the reel for holding the fabric more firmly. On the other hand, since the distance between the clamping rods 19 can be changed under the action of the rotation of the bolt 15, reels of different diameters can be effectively fixed and clamped to a certain extent.

[0029] During the specific implementation of the present invention, when using a coating machine containing the roller mechanism, a roller carrying the cloth roll to be processed and a roller for collecting the processed cloth will be respectively installed on the rollers at the unwinding end 2 and the winding end 3 of the machine base 1, that is, in the roller bearing mechanism proposed in this specification, the two rollers are installed in the same way. First, one end of the roller is placed on the bracket 2 13, so that the two contact ends 20 are located inside the roller, and the end face of the roller contacts the abutment disk 14 on this side. One hand holds the roller and keeps pressing on the abutment disk 14. Based on the consistent fit between the end face of the roller and the abutment disk 14, the current horizontal position of the roller is guaranteed. Then the other hand moves the handle inside the bracket 2 13 Hand 16, let the bolt 15 rotate and move, so that the distance between the contact ends 20 will be enlarged, until it is tightly against the inner wall of the roll and fixed. After ensuring that the rolls on the unwinding end 2 and the winding end 3 have been installed, rotate the screw 4 to make the brackets 10 on both sides approach the middle position of the screw 4 until the other end face of the roll is in contact with the other contact disk on the roller. At this time, the two contact ends 20 at the other end of the roller also extend into the interior of the roll, and the corresponding contact ends 20 are made to press against the inner wall of the roll by turning the handle 16. After the above steps are completed in this operation, the installation process is completed. After the coating machine is completed, the disassembly operation can be performed in the opposite steps of the installation method.

[0030] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
