Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening device technology, specifically to an online inspection and screening device for rubber preforms. Background Technology
[0002] In the rubber vulcanization process, the control and screening of rubber preforms is an essential step. While preforms are primarily supplied by the rubber extruder, they are not directly connected to the vulcanizing unit and require manual feeding and unloading. The quality of the rubber compound cut by the extruder is generally determined by its length. The extruder, integrated with the vulcanizing unit, is not in a stable operating state, frequently starting and stopping as needed by the vulcanization unit. Uncertainties such as temperature cross-sectional expansion rate and photoelectric reaction rate contribute to inconsistent quality; both excessively large and small sizes result in product defects. Therefore, to ensure the accuracy of vulcanization material usage, it is essential to add an online inspection and screening device for rubber preforms to the integrated automated vulcanization equipment. Utility Model Content
[0003] The purpose of this invention is to provide an online inspection and screening device for rubber preforms, which solves the problem of inconvenience in automatically screening and inspecting preforms during the processing of rubber preforms.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an online inspection and screening device for rubber preforms, comprising two mounting bases, one of which has a first profile fixedly connected to its top, and the other of which has a second profile fixedly connected to its top. Support bases are fixedly connected to the tops of both the first and second profiles. A mounting plate one is fixedly connected to the top of one of the support bases, and a mounting plate two is fixedly connected to the top of the other support base. A longitudinal cylinder is fixedly mounted on the top of the mounting plate one, and a transverse cylinder is fixedly mounted on the top of the mounting plate two. A material distribution frame is fixedly connected between the first and second profiles. A material distribution plate one, two, and three are slidably connected inside the material distribution frame. A material receiving plate is fixedly installed inside the material distribution frame. A weighing sensor is fixedly installed at the bottom of the material receiving plate. A sensor mounting plate is fixedly installed at the bottom of the weighing sensor, and a sensor support is fixedly connected to the bottom of the sensor mounting plate.
[0005] Preferably, the mounting base has multiple evenly distributed mounting holes inside. These mounting holes allow for the mounting base to be installed and secured.
[0006] Preferably, the sensor support has multiple evenly distributed mounting holes inside. These mounting holes allow for the installation and fixation of the sensor support.
[0007] Preferably, the sensor support is fixedly connected to the first profile and the sensor support is fixedly connected to the second profile. By designing the sensor support, the weighing sensor can be installed and supported.
[0008] Preferably, the output end of the transverse cylinder is slidably connected to the material distribution frame, and the output end of the transverse cylinder is fixedly connected to the material distribution plate. By designing the transverse cylinder, the material distribution plate can be moved.
[0009] Preferably, the output end of the longitudinal cylinder is slidably connected to the material distribution frame, and the output end of the longitudinal cylinder is fixedly connected to material distribution plate two and material distribution plate three.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention utilizes a weighing sensor to record the quality of the extruder's extruded rubber material as it falls onto a receiving plate. If the data is within a reasonable range, a signal is sent to the longitudinal cylinder module, which then pushes the rubber material onto the conveyor belt. If the data deviates too much, a transverse cylinder pushes the rubber material away from the receiving plate, thus connecting the extruder and vulcanizing machine. This eliminates the need for manual material inspection and ensures the integrity of the integrated automatic vulcanizing machine. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1 , Figure 2 An online inspection and screening device for rubber preforms includes two mounting bases 1. Each mounting base 1 has multiple evenly distributed mounting holes. These holes allow for the mounting and fixing of the mounting base 1. A first profile 2 is fixedly connected to the top of one mounting base 1, and a second profile 14 is fixedly connected to the top of the other mounting base 1. Support bases 10 are fixedly connected to the tops of both the first profile 2 and the second profile 14. A mounting plate 11 is fixedly connected to the top of one support base 10, and a mounting plate 12 is fixedly connected to the top of the other support base 10. The support bases 10 have mounting holes that mate with the mounting plates 11 and 12. These mounting holes allow the mounting plates 11 and 12 to be installed on the two support bases 10 respectively.
[0018] Please see Figure 1 , Figure 2 A longitudinal cylinder 16 is fixedly installed on the top of mounting plate 11. The output end of the longitudinal cylinder 16 is slidably connected to the material distribution frame 13. The output end of the longitudinal cylinder 16 is fixedly connected to the material distribution plate 8 and the material distribution plate 9. By designing the longitudinal cylinder 16, the material distribution plate 8 and the material distribution plate 9 can be moved. A transverse cylinder 7 is fixedly installed on the top of mounting plate 12. The output end of the transverse cylinder 7 is slidably connected to the material distribution frame 13. The output end of the transverse cylinder 7 is fixedly connected to the material distribution plate 6. By designing the transverse cylinder 7, the material distribution plate 6 can be moved.
[0019] Please see Figure 1 , Figure 2A material distribution frame 13 is fixedly connected between the first profile 2 and the second profile 14. A material distribution plate 6, a material distribution plate 8, and a material distribution plate 9 are slidably connected inside the material distribution frame 13. A material receiving plate 5 is fixedly installed inside the material distribution frame 13. A weighing sensor 4 is fixedly installed at the bottom of the material receiving plate 5. A sensor mounting plate 3 is fixedly installed at the bottom of the weighing sensor 4. A sensor support 15 is fixedly connected to the bottom of the sensor mounting plate 3.

The sensor support 15 has multiple evenly distributed mounting holes inside. By designing the mounting holes, the sensor support 15 can be installed and fixed.
[0020] The specific implementation process of this utility model is as follows: During use, the rubber material cut by the extruder in real time falls into the material receiving plate 5. The weighing sensor 4 records the quality data. If the data is within a reasonable range, the signal is fed back to the longitudinal cylinder 16 module, and the longitudinal cylinder 16 moves to push the rubber material into the conveyor belt. If the data deviation is too large, the transverse cylinder 7 pushes the rubber material away from the material receiving plate 5, realizing the connection between the extruder and the vulcanizing machine, eliminating the manual material inspection step, ensuring the integrity of the integrated automatic vulcanizing machine, the mechanism design is simple and clear, the failure rate is low, and maintenance is convenient; the purpose is clear, it can solve the problem with extremely low cost, and the benefit ratio is very high. The material distribution module composed of the material receiving plate 5 and the cylinder-alternating material distribution plate effectively realizes the movement of the rubber material in the longitudinal and transverse directions. At the same time, the rubber material will not go out of the range of the material receiving plate 5 under the restriction during the dropping process. Theoretically, the height difference between the extruder dropping port and the material receiving plate 5 is free, which is convenient for installation or improvement.
