Description

Technical Field

[0001] The utility model relates to the technical field of flat plate vulcanizing machines, in particular to a flat plate vulcanizing machine with adjustable spacing. Background Art

[0002] Vulcanization refers to the process in which rubber macromolecules react chemically with the cross-linking agent sulfur under heating to form a three-dimensional network structure. The rubber after vulcanization is called vulcanized rubber. Vulcanization is the last step in rubber processing, which can obtain finalized rubber products with practical value. The flat vulcanizer is the equipment used for the vulcanization of rubber products.

[0003] When the flat plate vulcanizer is in use, due to the different thickness of rubber, it is sometimes necessary to adjust the distance between the two hot pressing plates in the flat plate vulcanizer. However, the conventional flat plate vulcanizer has only one hot pressing plate that is hydraulically driven to lift and lower to complete the vulcanization operation, while the other hot pressing plate is fixed to the bracket by fasteners, which also makes it troublesome and inconvenient to adjust the maximum distance between the two plates.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 5 A plate vulcanizing machine with adjustable spacing includes a base 1, a top plate 8 is arranged on the base 1, guide shafts 2 are vertically installed at the bottom corners of the top plate 8, and the bottom of the guide shaft 2 is vertically fixed on the base 1;

[0026] A first mounting plate 3 is also provided above the base 1. The corners of the first mounting plate 3 are slidably mounted on the guide shaft 2 through sliding seats, and a first hydraulic cylinder 4 is vertically mounted at the bottom of the first mounting plate 3. The first hydraulic cylinder 4 is fixed on the base 1, and a first hot pressing plate 5 is installed on the top of the first mounting plate 3; a second mounting plate 6 is provided above the first mounting plate 3 in parallel. The edge of the second mounting plate 6 is slidably mounted on the guide shaft 2 through sliding seats, and a second hydraulic cylinder 7 is vertically mounted on the top of the second mounting plate 6. The second hydraulic cylinder 7 is fixed on the top plate 8, and a second hot pressing plate 9 is installed at the bottom of the second mounting plate 6. The second hydraulic cylinder 7 drives the second mounting plate 6 to rise and fall, so that the distance between the second mounting plate 6 and the first mounting plate 3 is adjustable; and the first hydraulic cylinder 4 can push the first hot pressing plate 5 close to the second hot pressing plate 9, so as to perform vulcanization operation on the rubber placed on the first hot pressing plate 5.

[0027] Furthermore, the top of the first hydraulic cylinder 4 is fixed to the bottom of the first mounting plate 3 by fasteners, and the bottom of the second hydraulic cylinder 7 is fixed to the second mounting plate 6 by fasteners, and the fasteners are bolts or screws, so that the mounting plate and the hot pressing plate can be removed from the guide shaft 2.

[0028] A hydraulic station is arranged in the base 1, and the hydraulic station is connected to the first hydraulic cylinder 4 and the second hydraulic cylinder 7 through conduits to provide power for the operation of the hydraulic cylinders; a controller is also arranged in the base 1, and the controller is connected to the hydraulic station through a wire. In actual use, the controller is a control host or a PLC logic controller.

[0029] Further, such as Figure 2 As shown, a accommodating cavity 27 is opened on the side of the base 1, and the hydraulic station and the controller are placed in the accommodating cavity 27, and a cover plate 28 is installed on the end of the accommodating cavity 27, so that the accommodating cavity 27 can be opened to perform maintenance and repair on the hydraulic station, the controller, etc.; in actual use, heat dissipation holes are also opened on the cover plate 28 to ventilate the interior of the accommodating cavity 27.

[0030] like Figure 1 and Figure 4 As shown, a plurality of first cavities 10 arranged at intervals are provided on one side of the first hot pressing plate 5, a first heating rod 11 is built in the first cavity 10, a first transmission line 12 is connected to the first heating rod 11, the other end of the first transmission line 12 is connected to a second transmission line 13, and the second transmission line 13 is connected to a controller;

[0031] A plurality of second cavities 14 are arranged at intervals on one side of the second hot pressing plate 9 close to the first transmission line 12. A second heating rod 15 is built in the second cavity 14. A third transmission line 16 is connected to the second heating rod 15. The other end of the third transmission line 16 is connected to a fourth transmission line 17. The other end of the fourth transmission line 17 is connected to the second transmission line 13.

[0032] Among them, the second transmission line 13 and the fourth transmission line 17 are both spiral wires, so that when the two mounting plates are moved, the second transmission line 13 and the fourth transmission line 17 can be freely extended and retracted, so that the transmission line is pulled due to the lifting and lowering of the mounting plates, thereby causing damage to the transmission line; a fixing frame 18 is arranged above the third transmission line 16, and the third transmission line 16 is fixed to the fixing frame 18 by a clamp 21, and a baffle 19 is installed at the bottom of the fixing frame 18, and a strip groove 20 is opened on the baffle 19, and the strip groove 20 runs through the bottom of the baffle 19, and the first transmission line 12 and the fourth transmission line 17 are connected to the fixing frame 18. The three transmission lines 16 all correspond to the strip grooves 20, and a strip plate 22 is provided below the fixing frame 18. The strip plate 22 is fixed to the base 1 through the fixing plate 24. A limiting groove 23 is provided on the strip plate 22, and the baffle 19 is placed in the limiting groove 23. The second transmission line 13 and the fourth transmission line 17 with telescopic bending are placed on the side of the baffle 19 away from the hot pressing plate, so as to shield the second transmission line 13 and the fourth transmission line 17 to prevent the second transmission line 13 and the fourth transmission line 17 from falling between the two hot pressing plates when bent and twisted, thereby causing damage.

[0033] like Figure 1 As shown, a compression spring 26 is sleeved on the guide shaft 2, the top of the compression spring 26 is fixed on the second mounting plate 6, and the bottom of the compression spring 26 is fixed on the limit seat 25. The limit seat 25 is slidably installed on the guide shaft 2 through a sliding seat, which acts as a buffer for the process of the first hot pressing plate 5 approaching the second hot pressing plate 9, thereby preventing the rubber from being damaged due to the instantaneous increase in pressure.

[0034] When in use, first control the second mounting plate 6 to be close to the first mounting plate 3 according to the thickness of the rubber, so as to adjust the distance between the two hot pressing plates, then take the rubber and place it on the first hot pressing plate 5, and start the heating rod to heat the hot pressing plate, then raise the first hot pressing plate 5, and squeeze the rubber through the two hot pressing plates to complete the vulcanization operation of the rubber.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
