DETAILED DESCRIPTION
[0027] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.
[0028] According to the embodiment of the utility model, a kind of discharge door structure is provided, and discharge door structure is arranged at the discharge port 1 of equipment main body, please refer to Figures 1 to 5The device includes: a discharge gate 2, which is used to open and close the discharge port 1. A sealing surface 21 is provided on the side of the discharge gate 2 near the discharge port 1. The discharge gate 2 is movably arranged along the discharge direction of the discharge port 1 so that the sealing surface 21 is sealed or disconnected from the end face of the discharge port 1; and a guide device, which includes a guide rod 31, which extends along the moving direction of the discharge gate 2 and is slidably connected to the discharge gate 2 and the guide rod 31.
[0029] Compared with the discharge gate in the prior art, the opening method of the discharge gate 2 in this embodiment is changed from a vertical force-bearing method to a parallel force-bearing method. This change in force-bearing method makes the force borne by the discharge gate 2 during opening and closing more reasonable, and the force-bearing method is more advantageous.
[0030] In this way, by controlling the horizontal movement of the discharge gate 2, the optimized force distribution allows the sealing surface 21 to fit better, ensuring that the sealing surface 21 can tightly fit the end face of the discharge port 1 when the discharge gate 2 is closed, thereby achieving an effective seal. Compared with the traditional vertical discharge gate, this method can provide a tighter and more reliable sealing effect. The guide device ensures that the discharge gate 2 moves along a predetermined trajectory during opening and closing, guaranteeing the accuracy and stability of the movement, while also providing reliable support for the discharge gate 2, further ensuring the sealing performance of the discharge gate.
[0031] The use of a horizontal discharge gate ensures that no material remains on the discharge gate 2 when it is open, and there is no gap between the sealing surface 21 and the discharge port 1 when it is closed. This prevents material leakage or gaps caused by residual material in the discharge port 1 being trapped between the sealing surface 21 and the discharge port 1, thus enhancing the overall sealing performance of the discharge gate and solving the technical problem of poor sealing of the discharge gate in extrusion equipment in related technologies.
[0032] Understandably, since the sealing surface 21 is an exposed surface, its processing technology is simpler and easier to manufacture compared to traditional sealing structures. This not only reduces the processing difficulty but also effectively reduces processing time and costs, solving the problems of difficult and costly processing of existing discharge doors.
[0033] In the discharge gate structure of this embodiment, see Figure 3 The guiding device includes a guide slider 32, which is fixedly mounted on the discharge gate 2 and slidably connected to the guide rod 31. By setting the guide slider 32, the guide slider 32 and the guide rod 31 cooperate with each other to ensure the stability of the movement of the discharge gate 2 and make the movement of the discharge gate 2 smoother.
[0034] In the discharge gate structure of this embodiment, see Figure 1The discharge gate structure includes: a mounting frame 4, on which the discharge gate 2 is mounted. There are two mounting frames 4, each positioned on opposite sides of the discharge gate 2. This arrangement allows the mounting frames 4 to mount the discharge gate 2, and the use of two mounting frames 4 enhances the stability of the discharge gate structure.
[0035] In the discharge gate structure of this embodiment, see Figure 3 The guide rod 31 is fixedly mounted on the mounting bracket 4. There are at least two guide rods 31, and the at least two guide rods 31 are located on two mounting brackets 4 respectively.
[0036] In some embodiments, the guide slider 32 may include at least two, and the at least two guide sliders 32 are configured in a one-to-one correspondence with at least two guide rods 31.
[0037] Specifically, the guide rod 31 is installed on the mounting bracket 4, and the discharge gate 2 is connected to the discharge gate 2 through the guide rod 31 and the guide slider 32, thereby realizing the installation and fixation of the discharge gate 2.
[0038] In some embodiments, see Figure 3 The mounting frame 4 has a clearance cavity 41, which accommodates the discharge gate 2 to facilitate the connection between the head of the piston rod 52 and the discharge gate 2. At the same time, a guide rod 31 is installed on the top or bottom of the clearance cavity 41. The guide rod 31 is inserted through the clearance cavity 41. Placing the guide rod 31 on the top or bottom of the clearance cavity 41 can maximize the area of the discharge gate 2 and make the whole structure more compact.
[0039] In the discharge gate structure of this embodiment, see Figure 1 and Figure 3 The discharge gate structure includes a drive cylinder 51, which is mounted on a mounting bracket 4. The piston rod 52 of the drive cylinder 51 is telescopically arranged along the discharge direction of the discharge port 1, and the head of the piston rod 52 is connected to the discharge gate 2. At least two drive cylinders 51 are included, each mounted on one of two mounting brackets 4. Compared to traditional power methods, the distribution of at least two drive cylinders 51 on both sides provides more even and stable power, resulting in smoother opening and closing of the discharge gate and more balanced force distribution.
[0040] In some embodiments, the drive cylinder 51 is a hydraulic cylinder, and the hydraulic cylinders on both sides are used as the power source for opening and closing the door. The hydraulic cylinders on both sides can provide power more evenly and stably.
[0041] In the discharge gate structure of this embodiment, see Figures 4-5The discharge gate structure includes a fixing device 61, which includes a fixing pin 611 located at the discharge port 1. The extension direction of the fixing pin 611 is perpendicular to the discharge direction of the discharge port 1. The discharge gate 2 is provided with a fixing slot 621 corresponding to the fixing pin 611. The fixing slot 621 is used to accommodate the fixing pin 611. The fixing pin 611 is telescopically oriented to connect or disconnect with the fixing slot 621. With this configuration, in the closed state, when the discharge gate 2 moves into position, the fixing pin 611 is controlled to extend or retract, thereby inserting the fixing pin 611 into the fixing slot 621. This prevents gaps from forming between the end faces of the discharge gate 2 and the discharge port 1. This design ensures extremely high stability of the discharge gate in the closed state, effectively preventing loosening of the discharge gate due to external forces or media pressure, thus improving sealing performance.
[0042] In the discharge gate structure of this embodiment, see Figure 4 The fixing pins 611 include multiple pins, which are spaced apart circumferentially along the discharge port 1. This arrangement of multiple fixing pins 611 ensures that the discharge gate has extremely high stability when closed, further improving the sealing performance of the discharge gate 2.
[0043] In the discharge gate structure of this embodiment, see Figure 4 The fixing device 61 includes multiple fixing devices 61, which are arranged at intervals around the periphery of the discharge port 1.
[0044] It is understandable that the number of fixing devices 61 can be set according to actual needs. For example, when the discharge gate structure is applied to the extrusion equipment, since the bottom of the discharge gate needs to discharge, in order to prevent material residue on the fixing devices 61, the fixing devices 61 can be set only on the top surface and / or side wall of the discharge port of the extrusion equipment.
[0045] Preferably, three fixing devices 61 are provided at the top and two sides of the discharge gate 2.
[0046] In some embodiments, an end plate 7 is provided on the end face of the discharge port 1, and a fixing device 61 is installed on the side of the end plate 7 away from the discharge gate 2. The fixing device 61 also includes a fixing base 612, and a plurality of fixing pins 611 are fixedly disposed on the fixing base 612. The discharge gate structure also includes a push plate 72 and a driving component 73 connected to the push plate 72. The driving component 73 is used for the push plate 72 to reciprocate. The push plate 72 has an abutting part that abuts against the fixing base 612. The push plate 72 pushes the fixing base 612 to reciprocate, thereby allowing the plurality of fixing pins 611 to be retractably disposed.
[0047] In some embodiments, the drive component 73 is a hydraulic cylinder.
[0048] In some embodiments, the discharge port includes a support plate 71 fixedly mounted on the end plate 7. The support plate 71 has multiple guide channels 711 that correspond one-to-one with multiple fixing pins 611. The guide channels 711 accommodate the fixing pins 611, thereby guiding the fixing pins 611 during their movement.
[0049] In some embodiments, fixing pins 611 are provided at the top and two sides of the end plate 7 to further improve the stability of the discharge gate.
[0050] In the discharge gate structure of this embodiment, see Figure 3 The discharge port 1 includes a baffle 62, which protrudes from the discharge gate 2 along the direction close to the discharge port 1. A fixing slot 621 is provided on the baffle 62. Multiple baffles 62 are arranged circumferentially around the discharge gate 2 and located on the periphery of the discharge port 1. By setting the baffles 62 around the discharge port 1, the opening direction of the fixing slot 621 corresponds to the fixing pin 611.
[0051] In the discharge gate structure of this embodiment, see Figure 3 The discharge gate 2 includes: a sealing groove 22, which is recessed on the sealing surface 21 and corresponds to the discharge port 1; and a sealing ring 23, which is embedded in the sealing groove 22. When the sealing surface 21 is sealed to the end face of the discharge port 1, the sealing ring 23 abuts against the end face of the discharge port 1. Thus, by opening the sealing groove 22 and embedding the sealing ring 23 on the discharge gate 2, leakage of the medium can be effectively prevented, greatly improving the sealing performance of the discharge gate 2.
[0052] Preferably, the sealing ring 23 is a rubber sealing ring, which gives the sealing ring 23 good elasticity and sealing performance, and can fit tightly in the sealing groove. When in contact with the medium, it can effectively prevent the leakage of the medium.
[0053] In practical applications, the discharge gate 2 is first installed in the main body of the equipment at the location of the pipeline where material flow needs to be controlled. When the discharge gate 2 needs to be opened, the two drive cylinders 51 are activated, pushing the discharge gate 2 to move parallel to the guide direction of the guide rod 31, thus opening the discharge gate 2. When closing the discharge gate 2, the two drive cylinders 51 move in the opposite direction, pushing the discharge gate 2 to the closed position. Then, the drive component 73 is activated, causing the fixing pins 611 on the top and two sides to extend and firmly fix the discharge gate 2. At this time, the sealing ring 23 is tightly fitted onto the sealing surface 21, effectively preventing material leakage. Throughout the process, the guide rod 31 and the guide slider 32 always provide accurate guidance and stable support for the movement of the discharge gate 2, ensuring that the discharge gate 2 can operate stably and reliably.
[0054] Applying the discharge gate structure of this embodiment to a material extrusion device enables the discharge port of the extrusion device to open and close horizontally. This effectively solves the problems of poor sealing, high cost, and difficult processing of the discharge gate of existing material extrusion devices. It has significant practicality and innovation, and brings positive impact and economic benefits.
