Description

Technical Field

[0001] The utility model relates to the technical field of filling object launching, in particular to a launching mechanism. Background Art

[0002] When the filler is launched, the launching mechanism needs to complete a long-stroke push in a short time to complete the launching action. The short time here usually refers to 1-1.5s, and the long stroke refers to a stroke of 800-900mm. To achieve this indicator, the launching mechanism needs to provide a thrust of about 20 tons for the filler.

[0003] Electric cylinders have become the first choice for launching mechanisms because they can achieve precise linear motion and withstand large loads. However, most electric cylinders currently available on the market use ball screws, which can only transmit at 1900-2300rpm, still unable to meet the requirement of providing 20 tons of thrust.

Detailed Description of the Preferred Embodiment

[0033] The present utility model will be described in detail below with reference to the accompanying drawings.

[0034] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0035] Embodiment 1

[0036] A launching mechanism, as Figure 1-4 shown, includes a launching mechanism body 3. The launching mechanism body 3 includes a driving module 35 and an execution module. The execution module includes a roller screw rod 34, a push rod 31 and a cylinder barrel 33. The roller screw rod 34 is rotatably connected inside the cylinder barrel 33. A threaded hole matching the roller screw rod 34 is provided in the length direction of the push rod 31. The push rod 31 is sleeved on the roller screw rod 34 through the threaded hole. The driving module 35 can drive the roller screw rod 34 to rotate so that the push rod 31 extends out of or retracts into the cylinder barrel 33.

[0037] One end of the push rod 31 in the length direction is provided with an opening of the threaded hole, and the other end is connected with a propulsion head 32 that can act on the filling.

[0038] The propulsion head 32 is a conical structure that gradually converges along the extending direction.

[0039] The propulsion head 32 is made of a flexible material to avoid rigid contact between the push rod 31 and the filling.

[0040] The driving module 35 and the execution module are arranged side by side, making the overall structure compact. The driving module 35 is rotatably connected to the roller screw rod 34 through a transmission structure 36. Preferably, the driving module 35 is a launching driving motor.

[0041] In the application of a certain launching mechanism, the power of the launching driving motor is 144 kW, the rated speed is 3000 rpm, the lead of the roller screw rod 34 is 36 mm, and the Dn value is 160000. The reduction ratio of the transmission structure 36 can be 1:2. The total time of the launching action process of the launching mechanism body 3 acting on the filling is 1.37 s, including an acceleration section of 0.4 s, a constant speed section of 0.52 s, and a deceleration section of 0.45 s. Among them, the travel in the acceleration section and the constant speed section is 650 mm, corresponding to the rapid propulsion of the filling, and the travel in the deceleration section is 200 mm, corresponding to the extrusion propulsion of the filling. In the deceleration section, the push rod 31 will move 200 mm and the speed will drop to 0 under the combined action of the resistance of the filling, inertia force, linear load, motor torque, friction resistance, etc.; thus, a propulsion travel of 850 mm can be completed in 1.37 s. It can be understood that the above travel setting is only for this embodiment, and travel settings with other values are also regarded as falling within the protection scope of this application.

[0042] Embodiment 2

[0043] Embodiment 2 is a further improvement on Embodiment 1; for further illustration, the same components will not be elaborated here, such as Figure 5-8 As shown, the main body 3 of the launching mechanism is installed on the adjusting bracket 42, and a loading bin 2 for providing loading materials is also carried on the adjusting bracket 42. The loading bin 2 is arranged side by side with the main body 3 of the launching mechanism. The adjusting bracket 42 can drive one of the loading bin 2 and the main body 3 of the launching mechanism to match with the loading port 411, and the loading port 411 corresponds to the launcher. Preferably, a pair of loading bins 2 are arranged side by side on both sides of the main body 3 of the launching mechanism, enabling dual-bin supply of loading materials. The dual-loading-bin 2 structure is convenient for carrying more types of loading materials for launching selection. More preferably, while the operation of launching and loading the loading materials is carried out in one loading bin 2, the operation of selecting the loading materials can be synchronously carried out in the other loading bin 2, effectively shortening the cycle time of launching the loading materials. The adjusting bracket 42 can move horizontally relative to the loading port 411 to make any loading bin 2 correspond to the loading port 411.

[0044] The adjusting bracket 42 moves relative to the connecting flange 41 through an adjusting drive assembly 43. The adjusting drive assembly 43 includes slide rails 431, sliders 432, gears 433, racks 434, an adjusting drive motor 435, and an adjusting reduction motor 436. A pair of slide rails 431 are respectively arranged at the top and bottom of the corresponding sides of the connecting flange 41 and the adjusting bracket 42. Racks 434 are also arranged at the corresponding sides of the connecting flange 41 and the adjusting bracket 42. The slide rails 431 are parallel to the racks 434. A number of sliders 432 matching the slide rails 431 are provided on the adjusting bracket 42. In this embodiment, each slide rail 431 corresponds to two sliders 432. An adjusting drive motor 435 is also installed on the adjusting bracket 42. The adjusting drive motor 435 is connected to the gear 433 through the adjusting reduction motor 436. The gear 433 meshes with the rack 434. After the adjusting drive motor 435 is started, it drives the gear 433 to rotate, causing the gear 433 to move along the rack 434, thereby driving the adjusting bracket 42 to move with the gear 433. At the same time, it also drives the sliders 432 on the adjusting bracket 42 to slide along the slide rails 431. Since the self-weight of the equipment is relatively large, and it is unreliable to rely only on the two slide rails 431 to bear the self-weight and the generated overturning moment, a sliding support device 5 is installed below the displacement area of the adjusting bracket 42. A number of universal balls 51 are arrayed and assembled at the corresponding positions on it and the adjusting bracket 42. Both ends of the sliding support device 5 are connected to the rocker 4. The sliding support device 5 provides an upward supporting force for the adjusting bracket 42, reducing the overturning moment of the slide rails 431. The adjusting bracket 42 can slide on the universal balls 51 along the moving direction, with high reliability, small frictional resistance, and low driving energy consumption.

[0045] Embodiment 3

[0046] Embodiment 3 is a further improvement of Embodiment 2; for further illustration, the same components will not be described again here. For example, Figure 9 , Figure 10 as shown, it further includes a cradle 4 that can adjust its position and pose according to the launching requirements, where the position and pose adjustment includes one or a combination of horizontal rotation, pitch adjustment, roll adjustment, and translation adjustment. The launcher and the adjustment bracket 42 are arranged inside the cradle 4. A connecting flange plate 41 is arranged between the launcher and the adjustment bracket 42. The connecting flange plate 41 is provided with a loading port 411 that can match the launcher. The adjustment bracket 42 can move horizontally along the connecting flange plate 41 and drive either the loading bin 2 or the launching mechanism body 3 to match the loading port 411.

[0047] A backstop mechanism 412 that can limit the one-way passage of the loaded object is provided at the loading port 411, and the backstop mechanism 412 can elastically yield under an external force.

[0048] A pushing mechanism 1 is assembled at the loading bin 2. The pushing mechanism 1 provides a moving thrust for the loading material in the loading bin 2. The loading material in the loading bin 2 can move from the pushing side of the loading bin 2 to the loading port 411 under the action of the moving thrust. A backstop mechanism 412 capable of elastic yielding is provided at the loading port 411. When the loading material passes through the loading port 411, under the action of the thrust, the backstop mechanism 412 matches the head end of the loading material and is compressed by the loading material to achieve elastic yielding. After the loading material passes through the loading port 411, the backstop mechanism 412 can extend out again under the action of the elastic force and restrict the tail end of the loading material to prevent the loading material from retreating during the pitching adjustment of the rocker 4. After the loading material moves in place, the pushing mechanism 1 retracts, and the adjusting bracket 42 moves relative to the connecting flange plate 41, so that the launcher body 3 is aligned with the loading port 411. The push rod 31 of the launcher body 3 extends out and acts on the loading material at the loading port 411, quickly pushing the loading material into the launcher for launching. After the launching is completed, the push rod 31 of the launcher body 3 retracts; the push rod 31 of the launcher body 3 can extend into the loading port 411 and provide a launching thrust for the loading material at the loading port 411. The loading material at the loading port 411 can be launched from the launcher under the action of the launching thrust; the launching thrust is greater than the moving thrust. The launching process of the loading material is divided into two stages. The first stage is that the pushing mechanism 1 provides a moving thrust to make the loading material move from the replenishing end 212 of the loading channel 21 to the loading port 411 of the connecting flange plate 41. The second stage is that the launcher body 3 provides a launching thrust to make the loading material quickly move into the launcher and be extruded for launching. Here, the launching thrust is much greater than the moving thrust. The moving thrust provided by the pushing mechanism 1 can be used for the loading material to move in the loading bin 2. The maximum launching thrust of the launcher body 3 is 20 tons. It can be understood that the value of the maximum launching thrust here can be set according to requirements. The maximum launching thrust of other values should also be regarded as falling within the protection scope of this application. Through the staged launching of the loading material, the excessive stroke of the launcher body 3 can be avoided, the equipment volume can be effectively reduced, the pitching moment of the launching device can be balanced, and the power of the whole machine can be reduced. The loading material can be restricted at the backstop mechanism 412, so the pushing mechanism 1 can push the loading material at any time during the pitching and direction movements, achieving the effect of flexibility and time saving.
