Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing. Specifically, it relates to an internal mixer for rubber support preparation with a waste slot for rubber material. Background Technique

[0002] The internal mixer is a kind of plastic mixing equipment that has been applied earlier in plastic product factories. In the calender production line, the internal mixer is located in front of the calender and behind the mixer. Its function is to mix and plasticize the uniformly mixed raw materials to provide a relatively uniformly mixed and plasticized molten material for the calender to calender and form plastic products. When producing cable materials, the internal mixer can directly plasticize the powdered materials mixed according to the formula into molten materials, then compress them into sheet-like tapes, and cut them into granules by a granulator. In the floor covering production line, it can directly provide a uniformly mixed and plasticized bottom coating for the fabric-based leather. It can also re-plasticize and recycle the recycled waste plastic film sheets on the internal mixer. When processing rubber hoses, a rubber internal mixer is needed;

[0003] According to a publicly disclosed internal mixer for rubber support preparation with a waste slot for rubber material (Publication No.: CN216884716 U): It includes a base and a pressure roller. A mounting plate is fixedly connected to the top of the base. A guiding mechanism is arranged on one side of the mounting plate, and a material spreading mechanism is arranged on one side of the mounting plate; the guiding mechanism includes a guiding plate, a guide rail, a dialing plate, a movable plate, and a magnetic attracting member. The guiding plate is fixedly connected to one side of the mounting plate. In the above application, a guiding mechanism is arranged on one side of the mounting plate, and a material spreading mechanism is arranged on one side of the mounting plate. After the internal mixer finishes working, the residual rubber materials inside the internal mixer are not cleaned, and manual cleaning is required, which needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an internal mixer for rubber support preparation with a waste slot for rubber material. By using a cleaning device to clean the inside of the internal mixer, when the internal mixer finishes working, there will be waste materials during the working process inside the mixing device. At this time, the mixing device is cleared by the material cleaning device. By starting the driving motor, the output shaft of the driving motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the gear to rotate. The rotation of the gear drives the rack to move. The rack slides through the moving groove. The movement of the rack drives the cleaning plate to move, and at the same time drives the brush to clean. During the movement of the cleaning plate, it will hit the force-bearing plate. The force-bearing plate drives the rotating shaft to rotate. The rotation of the rotating shaft drives the knocking plate to rotate. During the rotation of the knocking plate, it will knock on the baffle plate, generating vibrations, so that the waste materials sticking to the side of the baffle plate will fall off, solving the existing problems.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model relates to an internal mixer with a waste slot for rubber bearing preparation, which comprises a workbench. A work frame is fixedly connected to the top of the workbench, and an internal mixing device is fixedly connected inside the work frame;

[0015] Further, a second spring is fixedly connected to the inner wall of the waste box. One end of the second spring is fixedly connected to a pressure-receiving plate. The side surface of the pressure-receiving plate is elastically connected to the inner wall of the waste box through the second spring. The purpose of one end of the second spring being fixedly connected to the pressure-receiving plate is that when the waste in the waste box reaches a certain quantity, the pressure-receiving plate starts the alarm button through the second spring.

[0016] Further, the control end of the alarm button is located on the displacement track on the side of the pressure-receiving plate. The waste box is located below the waste chute. The inner shape of the discharge port is set as an inclined plane. The alarm button is located on the displacement track of the pressure-receiving plate so that the pressure-receiving plate can squeeze the alarm button during the movement. The waste box is located below the waste chute so that the waste can fall into the waste box when passing through the waste chute. The inner shape of the discharge port is set as an inclined plane to reduce the manual labor when taking out the waste box.

[0017] The working principle and beneficial effects of the present utility model are as follows:

[0018] The present utility model uses a cleaning device to clean the inside of the open mill. When the open mill finishes working, there will be waste generated during the working process inside the open mill device. At this time, the cleaning device is used to clean the open mill device. Through the mutual cooperation among components such as the driving motor, gears, and racks of the cleaning device, the brush is used for cleaning. During the movement of the cleaning plate, it will impact the force-receiving plate. The force-receiving plate drives the rotating shaft to rotate. The rotating shaft drives the knocking plate to rotate. During the rotation of the knocking plate, it will knock on the material blocking plate, generating vibrations, so that the waste adhering to the side of the material blocking plate will fall off. When the force-receiving plate is not impacted by the cleaning plate, the rotating shaft is reset through the torsion spring. The cleaning device can achieve the effect of automatically cleaning the inside of the open mill.

[0019] The present utility model collects the waste through a waste collection device. The waste enters the waste chute through the cleaning of the brush and then enters the waste box. When the waste accumulated in the waste box reaches a certain amount, the weight of the waste squeezes the pressure-receiving plate. The pressure-receiving plate squeezes the alarm button through the second spring. When the alarm button is triggered, the alarm light emits alarm light and flashes, thus reminding the staff that the waste box has reached the quantity that needs to be cleaned. At this time, the staff moves the blocking box door upward through the door handle. The blocking box door moves upward through the second chute. When the blocking box door leaves the discharge port, the waste box pops out elastically through the first spring, facilitating the staff to clean the waste inside the waste box.

[0020] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. Description of the Drawings
