Specifically, the slide base 1 can be a rectangular bottom plate structure, and baffles 11 perpendicular to the rectangular bottom plate structure are provided on three sides of the rectangular bottom plate structure to achieve. The slide cover 2 can be covered on the slide base 1 to form a cavity structure, so that components such as the front slide 3, the rear slide 4, and the gate 5 are installed in the cavity structure; to avoid dust generation during material filling of the device, preferably, the slide base 1 has a structure with baffles 11 on three sides, and the slide cover 2 has a structure with flanges 21 on three sides. The slide cover 2 is buckled on the slide base 1, and the three flanges 21 are buckled on the outer periphery of the three baffles 11, so that the cavity surrounded by the slide base 1 and the slide cover 2 is a cuboid structure with one side (such as Figure 3 the bottom surface shown) open; that is to say, both the slide base 1 and the slide cover 2 are rectangular plate-like structures. Baffles 11 perpendicular to the slide base 1 are provided on three sides of the slide base 1, and flanges 21 perpendicular to the slide cover 2 are provided on three sides of the slide cover 2. The three flanges 21 are respectively pressed and contacted and buckled on the three baffles 11 to achieve three-sided sealing of the cavity structure for shielding and protection, so as to avoid material flying and forming dust when the front slide 3, the rear slide 4, and the gate 5 are severely worn and the filled material leaks. Even if there is leakage, dust can be avoided, and foreign objects can also be prevented from entering the cavity structure to interfere with the internal components; at the same time, the opening of the bottom surface of the cavity can also enable the material to be discharged from the bottom opening, avoiding the accumulation of the material in the cavity and interfering with the swinging opening and closing of the gate 5. Even if there is leakage, the interference of the material on the swinging of the gate 5 can be avoided.

[0024] The front slide plate 3 is arranged inside the cavity structure; the rear slide plate 4 is arranged between the front slide plate 3 and the slide plate base 1 inside the cavity structure, and the rear slide plate 4 and the front slide plate 3 are arranged side by side along the thickness direction of the cavity structure (such as the horizontal direction shown in Figure 3 ); the gate plate 5 is clamped between the front slide plate 3 and the rear slide plate 4. Specifically, the front slide plate 3 and the rear slide plate 4 are arranged side by side inside the cavity structure along the thickness direction of the cavity structure (such as the horizontal direction shown in Figure 3 ), and the front slide plate 3 and the rear slide plate 4 are pressed and clamped on the left and right sides of the gate plate 5 (relative to the position shown in Figure 3 ) so that the gate plate 5 is clamped between the front slide plate 3 and the rear slide plate 4; when the gate plate 5 swings relative to the front slide plate 3 and the rear slide plate 4, the contact surface between the gate plate 5 and the front slide plate 3 and the contact surface between the gate plate 5 and the rear slide plate 4 generate friction; to improve the service life of the front slide plate 3, the rear slide plate 4, and the gate plate 5, preferably, the front slide plate 3, the rear slide plate 4, and the gate plate 5 can all be wear-resistant plates to reduce the wear caused by their friction, and further avoid the generation of gaps among the three, thereby further avoiding the occurrence of ash leakage. To improve the sealing performance between the slide plate cover 2 and the front slide plate 3, preferably, a rubber pad 8 is provided between the slide plate cover 2 and the front slide plate 3 to seal between the slide plate cover 2 and the front slide plate 3 to prevent ash leakage between the slide plate cover 2 and the front slide plate, so that the slide plate cover 2 and the front slide plate 3 fit and seal better; that is, from right to left (relative to the position shown in Figure 3 ), they are the slide plate cover 2, the rubber pad 8, the front slide plate 3, the gate plate 5, the rear slide plate 4, and the slide plate base 1 in sequence. In this embodiment, the gate plate 5 can be driven to rotate by the rotating shaft 7. Of course, the gate plate 5 can also move up and down relative to the front slide plate 3 and the rear slide plate 4 to align or block the discharge port, that is, to open and close the gate plate 5.

[0025] The elastic pressing assembly 6 is connected to the slide plate cover 2 to apply an elastic force to the slide plate cover 2 so that the slide plate cover 2 applies an elastic clamping force to the front slide plate 3, making the front slide plate 3, the rear slide plate 4, and the gate plate 5 fit tightly together. Specifically, the elastic pressing assembly 6 can also be connected to the slide plate base 1 to limit the slide plate base 1; the elastic pressing assembly 6 is also connected to the slide plate cover 2 to apply an elastic force to the slide plate cover 2, making the slide plate cover 2 press tightly against the right side wall of the rubber pad 8 (relative to the position shown in Figure 3At the position shown, an elastic clamping force is applied to the rubber pad 8 and is sequentially transmitted to the front slide plate 3, the gate plate 5, the rear slide plate 4, and the slide plate base 1, so that the contact surfaces between any two adjacent parts among the slide plate cover 2, the rubber pad 8, the front slide plate 3, the gate plate 5, the rear slide plate 4, and the slide plate base 1 are closely attached, thereby avoiding any gaps between any two adjacent parts and thus avoiding the occurrence of material leakage. In this embodiment, there are four elastic pressing components 6, which are respectively arranged at the four corners of the slide plate cover 2 to apply an elastic force to the four corners of the slide plate cover 2 and improve the tight fit degree among the front slide plate 3, the rear slide plate 4, and the gate plate 5. The arrangement of the elastic pressing components 6 always makes the front slide plate 3, the rear slide plate 4, and the gate plate 5 closely attached through the elastic force, and also allows the gate plate 5 to swing on its plane, that is, swing relative to the front slide plate 3 and the rear slide plate 4. This can not only avoid the existence of gaps, but also help to compensate for the thermal expansion and contraction of parts, and can overcome the influence of any back pressure change on the seal and prevent materials from entering the contact surfaces between any two of the front slide plate 3, the rear slide plate 4, and the gate plate 5, thus avoiding the occurrence of material leakage.

[0026] The rotating shaft 7 is rotatably passed through the slide plate base 1 and the rear slide plate 4, and the end of the rotating shaft 7 located inside the cavity structure (such as Figure 3 the right end shown) is cooperatively connected with the gate plate 5 to drive the gate plate 5 to swing so as to control the opening and closing of the gate plate 5 and realize the filling and stopping of materials. Specifically, the right end of the rotating shaft 7 (such as Figure 1 the right end shown) is provided with a transmission block 71 having a square cross-sectional structure, which is cooperatively connected with the square eccentric hole provided on the gate plate 5 to drive the gate plate 5 to swing, so that the discharge port provided on the gate plate 5 swings to a position coaxial with the discharge ports of the slide plate cover 2, the rubber pad 8, the front slide plate 3, the rear slide plate 4, and the slide plate base 1, that is, the opening of the gate plate 5 is realized, and the materials sequentially pass through the slide plate base 1, the rear slide plate 4, the gate plate 5, the front slide plate 3, the rubber pad 8, and the slide plate cover 2 to realize the filling of materials; or drive the gate plate 5 to swing to block the discharge port of the rear slide plate 4 through the gate plate 5, that is, the closing of the gate plate 5 is realized, and the filling of materials is stopped. To avoid interference between the slide plate base 1, the rear slide plate 4, the front slide plate 3, the rubber pad 8, etc. and the swing of the rotating shaft 7, preferably, an interference fit is provided between the rotating shaft 7 and the slide plate base 1, the rear slide plate 4, the front slide plate 3, and the rubber pad 8, that is, the rotating shaft 7 is rotatably passed through the slide plate base 1, the rear slide plate 4, the front slide plate 3, and the rubber pad 8.

[0027] In this embodiment, a discharge port in the form of a circular through-hole structure is provided on the skateboard base 1; in order to realize the positioning of the rear skateboard 4, preferably, the inner wall of the skateboard base 1 is provided with an inner boss structure at the discharge port of the skateboard base 1, which is used to position the rear skateboard 3, so that the discharge port of the rear skateboard 3 is clamped at the inner boss structure; of course, the outer wall of the skateboard base 1 is provided with an outer boss structure at the discharge port of the skateboard base 1, which is used to clamp and position it on a gate device such as a cement packaging machine, so that the device is clamped and positioned on the cement packaging machine as a whole. Among them, the inner boss structure and the outer boss structure can be an integrated structure to form a boss structure 12, and the boss structure 12, the three baffles 11 and the skateboard base 1 can all be an integrated structure to ensure the stability of the skateboard base 1.

[0028] In this embodiment, the slide cover 2 is provided with a discharge port in a circular through-hole structure; in order to avoid clogging of the material, preferably, the slide cover 2 is provided with an air inlet 22 on the outer periphery of the discharge port of the slide cover 2, for introducing compressed air, so as to activate the material to push the material to be quickly discharged from the discharge port of the slide cover 2, and avoid the clogging of the discharge port of the slide cover 2 by the material. Further preferably, an air supply ring 9 is provided on the inner wall of the slide cover 2 at the discharge port of the slide cover 2, and the air supply ring 9 is provided with an air supply hole (not shown in the figure) connected to the air supply hole 22, so that the compressed air passes through the air inlet 22 and the air supply hole of the air supply ring 9 in turn, activates the material in the discharge port, and pushes the material to be quickly discharged, and prevents clogging of the mouth. In order to avoid ash leakage between the air supply ring 9 and the slide cover 2, preferably, a felt ring 10 is provided between the air supply ring 9 and the slide cover 2 to seal the air supply ring 9 and the slide cover 2 to avoid leakage of materials from between the air supply ring 9 and the slide cover 2 during air supply and to avoid blockage caused by materials entering the air supply ring. The felt ring 10 is air permeable to prevent material transportation and allows compressed air to pass through and be blown into the air supply holes of the air supply ring 9. The air supply ring 9 and the felt ring 10 are also provided with a discharge port for material transportation. In this embodiment, one side of the air supply ring 9 (such as Figure 1 The right side of the figure is provided with an annular limiting notch 91 for limiting the position of the felt ring 10 so that the felt ring 10 is sleeved on the outer periphery of the annular limiting notch 91; in order to facilitate the fixing of the air supply ring 9 and the felt ring 10, preferably, the inner wall of the slide cover 2 (such as Figure 3 A clearance groove 23 is provided on the left side wall of the slide cover 2 at the discharge port of the slide cover 2, and the felt ring 10 and the air supply ring 9 are arranged in the clearance groove 23. At the same time, the left side wall of the air supply ring 9 is pressed against the left side wall of the rubber pad 8 to achieve the horizontal limit fixation of the air supply ring 9, and the rubber pad 8 can be used to achieve the sealing between the air supply ring 9 and the front slide 3 to prevent the material from leaking from between the air supply ring 9 and the front slide 3. Among them, the air inlet holes 22 can be multiple and arranged in a circle along the circumference of the discharge port of the slide cover 2 to ensure the uniformity of air supply; Figure 2As shown, in this embodiment, four are taken as examples for illustration. Of course, other quantities are also possible, and no limitation is made thereto in this embodiment.

[0029] Continue to refer to Figures 1 to 3 , the elastic pressing assembly 6 includes: a connecting rod 61, a first limiting member (not shown in the figure), a second limiting member 62, and a spring 63; wherein,

[0030] The connecting rod 61 passes through the skateboard base 1, the skateboard cover 2, the front skateboard 3, and the rear skateboard 4. Specifically, there is no connection relationship between the gate plate 5 and the connecting rod 61. At the same time, there is a gap between the connecting rod 61 and the gate plate 5 to avoid interfering with the swinging opening and closing of the gate plate 5. The connecting rod 61 can pass through the skateboard base 1, the rear skateboard 4, the front skateboard 3, the rubber pad 8, and the skateboard cover 2 in sequence from left to right, and both ends of the connecting rod 6 can be arranged outside the wall structure.

[0031] The first limiting member is arranged on the connecting rod 61 for pressing against the outer wall of the skateboard base 1 (such as Figure 3 the left side wall shown). Specifically, the first limiting member can be located on the side of the skateboard base 1 facing away from the skateboard cover 2 (such as Figure 3 the left side shown) to press against the outer wall of the skateboard base 1 to achieve the limitation of the outer wall of the skateboard base 1. The first limiting member can be connected to the connecting rod 61 in a position-adjustable manner along the length direction of the connecting rod 61 (such as Figure 3 the horizontal direction shown). For example, the first limiting member is sleeved on the connecting rod 62 and is threadedly connected to the connecting rod 62 so as to adjust the position of the first limiting member, and further adjust the limiting position of the skateboard base 1; of course, the first limiting member can also be fixedly connected to the connecting rod 61. For example, the first limiting member and the connecting plate 61 can be an integral structure, and no limitation is made to the connection relationship between the first limiting member and the connecting rod 61 in this embodiment.

[0032] The second limiting member 62 is arranged on the side of the skateboard cover 2 facing away from the skateboard base 1 (such as Figure 3 the right side shown), and the second limiting member 62 is connected to the connecting rod 61 in a position-adjustable manner along the length direction of the connecting rod 61. Specifically, the second limiting member 62 can be sleeved on the connecting rod 61 and is threadedly connected to the connecting rod 61 to adjust the position along the length direction of the connecting rod 62, that is, to move closer to or away from the skateboard cover 2, and further adjust the compression degree of the spring 63, that is, adjust the elastic force of the spring 63.

[0033] The spring 63 is sleeved outside the connecting rod 61, and the spring 63 is located between the slide plate cover 2 and the second limiting member 62 to apply an elastic force to the slide plate cover 2, so that the slide plate base 1, the slide plate cover 2, the front slide plate 3, and the rear slide plate 4 are clamped between the first limiting member and the spring 63. Specifically, after the elastic performance of the spring 63 decreases after long-term use, the compression amount of the spring 63 can be adjusted by adjusting the position of the second limiting member 62 along the connecting rod 61 to ensure the close fit among the front slide plate 3, the rear slide plate 4, and the gate plate 5.

[0034] In this embodiment, the connecting rod 61 can be a double-headed bolt, and the first limiting member and the second limiting member 62 are respectively nuts threadedly connected to both ends of the double-headed bolt. Of course, it can also be of other structures, and no limitation is made thereto in this embodiment. Among them, the first limiting member can also be fixedly connected to the slide plate base 1 to realize the connection and fixation between the connecting rod 61 and the first limiting member by screwing the connecting rod 61. To improve the connection stability between the slide plate base 1 and the rear slide plate 4, preferably, a limiting protrusion 611 is further provided on the connecting rod 61 to limit the rear slide plate 4, so that the rear slide plate 4 is limited between the first limiting member and the limiting protrusion 611, thereby fixing the rear slide plate 4 to the slide plate base 1, and at the same time, the detachable connection between the slide plate base 1 and the rear slide plate 4 can be realized; meanwhile, the limiting protrusion 611 can also be a hexagonal protrusion structure corresponding to a wrench to cooperate with the wrench to screw the connecting rod 61, thereby facilitating the disassembly and assembly of each component. Among them, the thickness of the limiting protrusion 611 is less than the thickness of the gate plate 5 to avoid interfering with the pressing of the front slide plate 3 on the gate plate 5.

[0035] In this embodiment, the material can be not only cement ash but also other materials, and no limitation is made thereto in this embodiment; that is to say, this new type of gate plate device can be not only applied to a cement packing machine but also to equipment for controlling the inlet and outlet of materials to control the inlet and outlet of materials, etc.

[0036] In summary, the novel gate device provided by this embodiment forms a partially sealed cavity structure through the slide base 1 and the slide cover 2; an elastic force is applied to the slide cover 2 through the elastic pressing component, so that the slide cover 2 applies an elastic clamping force to the front slide 3, and further enables the gate 5 to be closely attached and clamped between the front slide 3 and the rear slide 4, avoiding gaps between the front slide 3, the gate 5 and the rear slide 4, and thus avoiding the occurrence of material leakage. At the same time, the setting of the elastic pressing component 6 always makes the front slide 3, the rear slide 4 and the gate 5 closely attached through the elastic force, and allows the valve plate 5 to swing on its plane, that is, move relative to the front slide 3 and the rear slide 4. This not only can avoid the existence of gaps, that is, no dust leakage will occur during the process of opening and closing the gate, but also helps to compensate for the thermal expansion and contraction of parts, and can overcome the influence of any back pressure change on the seal and prevent materials from entering the close contact surfaces between any two of the front slide 3, the rear slide 4 and the gate 5, avoiding the occurrence of material leakage; in addition, the shield composed of the slide base 1 and the slide cover 2 can ensure that no dust will be raised even if dust leakage occurs in time.
