Description

Technical Field

[0001] The present application relates to the field of vulcanizers, and in particular to a drum vulcanizer for rubber processing. Background Art

[0002] The drum vulcanizer is one of the indispensable equipment in the rubber processing process. It is mainly used for heating and vulcanizing the rubber belt. It can continuously vulcanize various rubber-coated fabrics. The main working parts are the vulcanization drum and the steel belt. The steel belt will press the rubber fabric tightly against the surface of the vulcanization drum, and vulcanize the rubber layer on the rubber fabric by heating. In the patent with the publication number of CN213890873U, a drum vulcanizer for rubber processing is disclosed. The support member in the support mechanism contacts the gauze wrapped around the outer side of the vulcanization drum, thereby preventing the gauze wrapped around the outer side of the vulcanization drum from detaching, so that the partially smooth rubber products will not be adhered to the vulcanization drum during the vulcanization process. After each vulcanization, only the gauze needs to be replaced, which is simple and convenient to use.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the above-mentioned patent has the defect that it is difficult to prevent the gauze from wrinkling. Since the above-mentioned patent only uses rollers to support the gauze, the gauze will inevitably move relative to the vulcanization drum during the rotation of the vulcanizing drum, thereby causing wrinkles in the gauze and affecting the processing of the rubber. Therefore, a drum vulcanizer for rubber processing is proposed to solve the above-mentioned problem.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem in the comparative patent that it is difficult to prevent the gauze from wrinkling, the present application provides a drum vulcanizer for rubber processing.

[0006] The present application provides a rubber processing drum vulcanizer adopts the following technical solution:

[0007] A drum vulcanizer for rubber processing comprises a vulcanizer body, a rotating shaft is mounted on the vulcanizer body, a roller is mounted on the side wall of the rotating shaft, gauze is mounted on the roller, two buckle plates are mounted on the outer wall of the gauze, the bottom walls of the two buckle plates are both against the side walls of the gauze, fixing rings are respectively mounted on the side walls at both ends of the rotating shaft, two fixing plates are mounted on the fixing rings, and a limiting mechanism is mounted between the fixing plates and the buckle plates.

[0008] Preferably, the cross-section of the gusset plate is "U"-shaped, a portion of the bottom wall of the gusset plate abuts against the side wall of the gauze, and another portion abuts against the side wall of the drum.

[0009] Preferably, the limiting mechanism includes a connecting rod, an extension rod, a first protrusion, a second protrusion, a translation rod and a plurality of springs, the connecting rod is installed on the side wall of the buckle plate, the top wall of the fixed plate is provided with a through hole, a working cavity is provided in the fixed plate, the through hole is communicated with the working cavity, the connecting rod is fixedly connected to the side wall of the extension rod through the through hole, the first protrusion is installed on the side wall of the extension rod, the translation rod is slidably connected to the side wall of the working cavity, the second protrusion is installed on the side wall of the translation rod, the side wall of the first protrusion is abutted against the side wall of the second protrusion, and the plurality of springs are respectively installed between the side wall of the working cavity and the side wall of the translation rod.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a drum vulcanizing machine for rubber processing. Figure 1 A drum vulcanizer for rubber processing comprises a vulcanizer body 1, a rotating shaft 2 is arranged on the vulcanizer body 1, a roller 3 is arranged on the side wall of the rotating shaft 2, a gauze 4 is arranged on the roller 3, two gussets 5 are arranged on the outer wall of the gauze 4, the bottom walls of the two gussets 5 are both against the side walls of the gauze 4, the cross section of the gusset 5 is "U" shaped, a part of the bottom wall of the gusset 5 is against the side wall of the gauze 4, and the other part is against the side wall of the roller 3, and the "U" shaped gusset 5 is more convenient to fit the roller 3, so that the gauze 4 is firmly fixed on the roller 3;

[0020] Reference Figure 2 , the side walls at both ends of the rotating shaft 2 are respectively provided with fixing rings 6, and two fixing plates 7 are installed on the fixing rings 6. The positions of the two fixing plates 7 correspond to the positions of the gusset plates 5, which can more conveniently fix the positions of the gusset plates 5;

[0021] Reference Figure 3 A limiting mechanism is installed between the fixed plate 7 and the gusset plate 5, and the limiting mechanism includes a connecting rod 8, an extension rod 9, a first protrusion 10, a second protrusion 11, a translation rod 12 and a plurality of springs 13. The connecting rod 8 is installed on the side wall of the gusset plate 5, a through hole 14 is opened on the top wall of the fixed plate 7, a working cavity is opened in the fixed plate 7, and the through hole 14 is connected to the working cavity. The connecting rod 8 passes through the through hole 14 and is fixedly connected to the side wall of the extension rod 9. The first protrusion 10 is installed on the side wall of the extension rod 9, and the translation rod 12 Slidingly connected with the side wall of the working chamber, the second protrusion 11 is installed on the side wall of the translation rod 12, the side wall of the first protrusion 10 is against the side wall of the second protrusion 11, the end of the first protrusion 10 close to the second protrusion 11 is designed in an arc shape, and the end of the second protrusion 11 close to the first protrusion 10 is also designed in an arc shape. The arc-shaped first protrusion 10 and the second protrusion 11 are more convenient for mutual extrusion, and one end is arc-shaped and the other end is not arc-shaped, which is convenient for the first protrusion 10 and the second protrusion 11 to limit each other's position;

[0022] A plurality of springs 13 are respectively installed between the side wall of the working chamber and the side wall of the translation rod 12. The springs 13 enable the first protrusion 10 to always keep in contact with the second protrusion 11, so that the position of the pinch plate 5 is fixed;

[0023] A moving rod 15 is installed on the side wall of the translation rod 12 away from the spring 13. The moving rod 15 passes through the side wall of the working chamber. A pull rod 16 is installed on one end of the two moving rods 15 away from the translation rod 12. The pull rod 16 can drive the two moving rods 15 at the same time, thereby improving the efficiency of replacing the gauze 4.

[0024] The implementation principle of a drum vulcanizer for rubber processing in an embodiment of the present application is as follows: when the rotating shaft 2 drives the roller 3 and the gauze 4 to rotate, the gauze 4 can prevent the rubber product from sticking to the roller 3, and the buckle plate 5 can firmly fix the gauze 4 on the roller 3, effectively preventing the gauze 4 from wrinkling during the rotation process. When the gauze 4 needs to be replaced, the pull rod 16 can be pushed inward, and the two moving rods 15 will drive the translation rod 12 to move together, while compressing the spring 13, making the second protrusion 11 move away from the second protrusion 11. At this time, the second protrusion 11 loses the restriction of the first protrusion 10, and the extension rod 9 and the connecting rod 8 will lose the force to restrict the position of the buckle plate 5, and the staff can easily remove the gauze 4 for replacement.
