Description

Technical Field

[0001] The utility model relates to the technical field of rubber corner jointing machines, in particular to a rubber corner jointing machine with an auxiliary rubber clamping plate. Background Art

[0002] The rubber jointing machine is a special mechanical equipment used to produce rubber products. Its main function is to hot-press the rubber strips at both ends to form an integrated rubber joint. It is widely used in the production of various rubber products such as sealing strips, tapes, shock absorbers, etc. The equipment is usually composed of a heating device, a pressure device, a transmission device, a control device and other parts. By precisely controlling parameters such as temperature, pressure and time, high-temperature vulcanization and joining of rubber strips can be achieved, thereby ensuring the wear resistance, sealing and strength of the joint.

[0003] In combination with the rubber corner joining machines in the prior art, it is found that when the rubber corner joining machines are used, the heating and melting steps of the colloid in the existing rubber corner joining machines during the production process have problems such as low heating efficiency, high energy consumption and uneven heating, which can easily lead to the problem of low quality of rubber jointing. In addition, the corner joining mold also has stability problems, especially the situation that the colloid injection is prone to misalignment, which may cause the corner joining operation to fail.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a fixing mechanism is provided. By means of pneumatic adsorption, the fixing mechanism can stably fix the mold and ensure the position stability of the mold on the auxiliary clamping plate, thereby reducing the dislocation phenomenon of colloid injection caused by mold movement and improving the success rate of corner connection operation. After the stability of the mold is enhanced, the operator can complete the positioning and corner connection operation of the mold more quickly, thereby improving the overall production efficiency and reducing production interruptions caused by operational errors. The stabilizing effect of the fixing mechanism reduces the wear of the mold caused by frequent movement or instability, extends the service life of the mold, and reduces maintenance costs.

[0014] 2. In the utility model, a preheating mechanism is provided. The preheating mechanism ensures that a large amount of glue liquid is available at any time by heating a variety of colloids in advance, reduces production delays caused by waiting for the glue liquid to be heated, and improves the overall corner joint efficiency. The preheating mechanism ensures that the colloid is fully melted before entering the mold through long-term heating, thereby ensuring the quality of the glue liquid and improving the sealing and durability of the corner joint. Since the preheating mechanism can preheat the colloid before production, the need for immediate heating of the colloid during the production process is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

The fixing mechanism 8 includes an auxiliary splint 801, an air groove 802, an air guide pipe 803, an air pump body 804, a pump body bracket 805 and a hydraulic rod 806. A hydraulic rod 806 is fixedly installed on the bottom end of the machine room 1, and an auxiliary splint 801 is fixedly connected to the upper end of the hydraulic rod 806. An air groove 802 is opened inside the auxiliary splint 801, and the air groove 80 2 is fixedly connected with an air guide pipe 803, an end of the air guide pipe 803 away from the air groove 802 is fixedly installed with an air pump body 804, a pump body bracket 805 is fixedly installed at the lower end of the air pump body 804, and the pump body bracket 805 is fixedly installed at the left end of the auxiliary clamping plate 801, a transmission rod 3 is arranged below the hydraulic cylinder 2, the transmission rod 3 is fixedly connected to the transmission end of the hydraulic cylinder 2, a liquid guide pipe 4 is arranged below the transmission rod 3, a mounting seat 5 is arranged outside the liquid guide pipe 4, the mounting seat 5 is fixedly installed on the cabin 1, a mold 6 is arranged below the mounting seat 5, and a rubber block 7 is arranged in the middle of the mold 6;

[0027] Through the air groove 802 and the air guide pipe 803, the auxiliary splint 801 can stably adsorb the mold 6, ensuring its position stability on the auxiliary splint 801, thereby reducing the phenomenon of colloid injection dislocation and improving the success rate of the corner connection operation. The air pump body 804 draws air from the air groove 802 through the air guide pipe 803 to generate sufficient negative pressure, so that the auxiliary splint 801 can stably adsorb the mold 6, providing a stable working environment for the operator. The air guide pipe 803 connects the air pump body 804 and the air groove 802 to provide the necessary gas flow path for pneumatic adsorption, ensuring the pneumatic performance of the fixing mechanism 8

[0028] The preheating mechanism 9 includes a heating chamber 901, a placement seat 902, a heating wire 903, a preheating box 904 and a liquid injection bucket 905. The heating chamber 901 is fixedly installed at both ends of the hydraulic cylinder 2. The placement seat 902 is installed inside the heating chamber 901. The heating wire 903 is installed on the placement seat 902. The preheating box 904 is arranged above the heating wire 903. Multiple groups of placement seats 902, heating wires 903 and preheating boxes 904 are distributed from top to bottom on the inner side of the heating chamber 901. The liquid guide pipe 4 is plugged with a liquid injection bucket 905.

[0029] The heating wire 903 heats the preheating box 904 for a long time, and heats the colloids of various properties to a molten state in advance, thereby ensuring the supply efficiency of the glue liquid, and also improving the temperature uniformity of the glue liquid, ensuring the quality of the joint. The preheating box 904 is used to place the colloid that needs to be preheated.

[0030] The working principle of the utility model is as follows: the rubber angle jointing machine with auxiliary rubber splints is additionally provided with a fixing mechanism 8 and a preheating mechanism 9. Before using the rubber angle jointing machine with auxiliary rubber splints, it is necessary to pre-connect the hydraulic cylinder 2, the air pump body 804, the hydraulic rod 806 and the heating wire 903 to electricity and connect to the control terminal. When using the rubber angle jointing machine with auxiliary rubber splints, firstly place the rubber block 7 to be connected on the mold 6, and place the mold 6 on the auxiliary splint 801, then activate the fixing mechanism 8, start the air pump body 804 to extract air from the air guide pipe 803 and the air groove 802, so as to achieve the effect of stable adsorption of the mold 6 and ensure the stability of the mold 6 on the auxiliary splint 801. At the same time, the user selects the glue liquid to be injected, activates the preheating mechanism 9 (the heating wire 903 in the preheating mechanism 9 is heated for a long time, which can melt the colloid in the preheating box 904 and obtain the glue liquid that can be directly used), removes the preheating box 904, and preheats the preheating box 904. The glue in the hot box 904 is injected into the liquid guiding pipe 4 through the liquid injection bucket 905. At this time, the hydraulic cylinder 2 and the hydraulic rod 806 are started. The hydraulic rod 806 pushes the auxiliary splint 801 and the mold 6 upward, so that the slot on the mold 6 is opposite to and fits with the liquid guiding pipe 4. Then the hydraulic cylinder 2 is started to push the transmission rod 3 downward. The transmission rod 3 presses down the glue in the liquid guiding pipe 4, so that the glue enters the mold 6 and achieves the effect of docking the rubber block 7. In summary, the fixing mechanism 8 adopts a pneumatic adsorption method, and cooperates with the auxiliary splint 801 to fix the mold 6, ensuring the position stability of the mold 6, so that the slot on the mold 6 is opposite to the liquid guiding pipe 4, which improves the stability and reliability of the subsequent addition of glue. In addition, the preheating mechanism 9 adopts an advance heating method to place colloids of various properties in the preheating box 904, preheat a variety of colloids in advance, obtain a large amount of glue, thereby ensuring the supply efficiency of the glue and improving the corner joining efficiency of the rubber corner joining machine.
