Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing and agitating technology, and in particular to a movable sealing device for a bottom-discharge mixing and agitating machine. Background Technology
[0002] The discharge port of the existing bottom discharge mixing mixer is located at the bottom of the mixing pot. The discharge port is closed or opened by the up and down movement of the sealing plate located below the mixing pot. Since the material discharged from the discharge port needs to be conveyed to the front or left and right sides of the machine, the sealing plate usually moves along the center of the mixing pot towards the rear of the machine after completing the vertical opening action. Otherwise, it will hinder the conveying of the material after it falls.
[0003] As the sealing disc moves backward, a gap gradually forms between the sealing disc and the discharge port at the bottom of the mixing pot. The mixed material inside the mixing pot will fall freely through this gap for discharge. During this process, a certain amount of material will adhere to the sealing disc. Before the next mixing operation, the material adhering to the sealing disc must be cleaned to ensure good sealing conditions.
[0004] However, because the sealing disc is located below the mixing pot and at the rear of the machine, cleaning the material stuck to the sealing disc is time-consuming, laborious, and inefficient. Utility Model Content
[0005] The purpose of this invention is to provide a mobile sealing device for a bottom-discharge mixing mixer to solve the problems existing in the above-mentioned related technologies and facilitate the cleaning of materials adhering to the sealing disc.
[0006] To achieve the above objectives, this utility model provides the following solution:
[0007] This utility model provides a movable sealing device for a bottom-discharge mixing mixer, including a support base, a horizontal linear slide rail, a sealing disc, a vertical moving mechanism, and a front-back moving mechanism. The front end of the support base has a vertically arranged discharge channel, the upper end of which communicates with the discharge port of the mixing pot. The horizontal linear slide rail is fixed to the bottom of the front end of the support base and extends in the front-back direction. At least two horizontal linear slide rails are provided, each located on one side of the discharge channel. The sealing disc is positioned between the two horizontal linear slide rails via the vertical moving mechanism. The front-back moving mechanism is located at the bottom of the rear end of the support base and can drive the vertical moving mechanism to slide along the two horizontal linear slide rails. When the vertical moving mechanism slides to a position close to the discharge channel, it can move the sealing disc up and down to seal or open the discharge channel. The front end of the support base has a cleaning port. When the vertical moving mechanism slides to a position close to the cleaning port, the cleaning port exposes the sealing disc for cleaning.
[0008] Preferably, the cleaning port is U-shaped.
[0009] Preferably, the vertical moving mechanism includes a cylinder connecting plate and a vertical cylinder. The two sides of the cylinder connecting plate are slidably connected to the two horizontal linear slide rails via a sliding block. The vertical cylinder is disposed below the cylinder connecting plate and is fixedly connected to the cylinder connecting plate. The piston rod of the vertical cylinder is vertically upward and passes through the cylinder connecting plate to connect to the sealing disc. The piston rod of the vertical cylinder can drive the sealing disc to move up and down.
[0010] Preferably, the vertical moving mechanism further includes a bearing assembly, and the piston rod of the vertical cylinder is connected to the sealing disc through the bearing assembly.
[0011] Preferably, the vertical hydraulic cylinder is a lifting hydraulic cylinder.
[0012] Preferably, the forward and backward moving mechanism includes a horizontal hydraulic cylinder, which is disposed at the rear end of the support base, and the piston rod of the horizontal hydraulic cylinder is horizontally forward and connected to the hydraulic cylinder connecting plate.

[0015] Preferably, the horizontal hydraulic cylinder is a telescopic hydraulic cylinder.
[0016] Preferably, the discharge channel is a cylindrical channel, and the upper opening of the discharge channel is a frustum-shaped opening; the sealing disc has a frustum structure and matches the upper opening of the discharge channel.
[0017] This utility model achieves the following technical advantages compared to related technologies:
[0018] The movable sealing device for a bottom-discharge mixing mixer provided by this utility model includes a support base, horizontal linear slide rails, a sealing disc, an up-and-down moving mechanism, and a front-and-back moving mechanism. In use, the discharge channel at the front end of the support base is aligned with the discharge port of the mixing pot of the bottom-discharge mixing mixer. First, the up-and-down moving mechanism is driven by the front-and-back moving mechanism to slide forward along the two horizontal linear slide rails at the front end of the support base until the up-and-down moving mechanism is located close to the discharge channel. Then, the sealing disc is driven by the up-and-down moving mechanism to move upward to seal the discharge channel.

The sealing disc is then exposed through the cleaning port, making the subsequent cleaning of the material adhering to the sealing disc simple and easy to operate. Attached Figure Description

[0027] The purpose of this invention is to provide a mobile sealing device for a bottom-discharge mixing mixer to solve the problems existing in related technologies and facilitate the cleaning of materials adhering to the sealing disc.
[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] like Figure 1As shown, this embodiment provides a movable sealing device for a bottom-discharge mixing mixer, including a support base 1, a horizontal linear slide rail 2, a sealing disc 3, a vertical moving mechanism 4, and a front-back moving mechanism 5. A discharge channel 101 is vertically arranged at the front end of the support base 1, and the upper end of the discharge channel 101 is used to communicate with the discharge port of the mixing pot body 01. The horizontal linear slide rail 2 is fixed to the bottom of the front end of the support base 1 and extends in the front-back direction. At least two horizontal linear slide rails 2 are provided, with the two horizontal linear slide rails 2 located on both sides of the discharge channel 101. The sealing disc 3 is arranged between the two horizontal linear slide rails 2 via the vertical moving mechanism 4, and the front-back moving mechanism 5 is arranged on the support base. The bottom of the rear end of the support base 1 can drive the up and down moving mechanism 4 to slide along two horizontal linear slide rails 2; when the up and down moving mechanism 4 slides to a position close to the discharge channel 101, the up and down moving mechanism 4 can move the sealing disc 3 up and down to seal or open the discharge channel 101; the front end of the support base 1 is provided with a cleaning port 102. When the up and down moving mechanism 4 slides to a position close to the cleaning port 102, the cleaning port 102 can expose the sealing disc 3 for cleaning; specifically, the cleaning port 102 at the front end of the support base 1 is preferably a U-shaped port, the size of the cleaning port 102 matches the sealing disc 3, and the rear end of the support base 1 is supported on the ground by the base 103.
[0030] In this embodiment, the vertical moving mechanism 4 includes a cylinder connecting plate 401 and a vertical cylinder 402. The two sides of the cylinder connecting plate 401 are slidably connected to two horizontal linear slide rails 2 via a slide block. Specifically, in this embodiment, the two slide blocks are slidably connected to the two horizontal linear slide rails 2, and the upper surfaces of the two slide blocks are screwed to the lower surfaces of the two sides of the cylinder connecting plate 401. In this embodiment, the vertical cylinder 402 is preferably a lifting cylinder. The vertical cylinder 402 is located below the cylinder connecting plate 401 and is fixedly connected to the cylinder connecting plate 401. The piston rod of the vertical cylinder 402 is vertically upward and passes through the cylinder connecting plate 401 to connect to the sealing disc 3. The piston rod of the vertical cylinder 402 can drive the sealing disc 3 to move up and down.
[0031] Furthermore, the vertical moving mechanism 4 also includes a bearing assembly. The piston rod of the vertical cylinder 402 is connected to the sealing disc 3 through the bearing assembly. Specifically, the bearing assembly in this embodiment includes a rolling bearing 403 and a bearing end cap 404. Both the rolling bearing 403 and the bearing end cap 404 are disposed inside the sealing disc 3. The piston rod of the vertical cylinder 402 is connected to the bearing inner hole of the rolling bearing 403. The upper surface of the cylinder body of the vertical cylinder 402 is screwed to the lower surface of the cylinder connecting plate 401. The center of the sealing disc 3 can coincide with the center of the mixing pot body 01. Under the action of hydraulic pressure, the piston rod of the vertical cylinder 402 can drive the sealing disc 3 to complete the vertical opening and sealing action.
[0032] In this embodiment, the forward and backward moving mechanism 5 includes a horizontal cylinder 501. The horizontal cylinder 501 in this embodiment is preferably a telescopic cylinder. The horizontal cylinder 501 is located at the rear end of the support base 1, and the piston rod of the horizontal cylinder 501 is horizontally forward and connected to the cylinder connecting plate 401. The piston rod of the horizontal cylinder 501 can drive the cylinder connecting plate 401 to move forward and backward.
[0033] In this embodiment, the forward and backward moving mechanism 5 also includes a first bearing seat 502 and a second bearing seat 503. The piston rod of the horizontal cylinder 501 is hinged to the cylinder connecting plate 401 through the first bearing seat 502, and the shaft of the first bearing seat 502 extends in the vertical direction. The tail end of the horizontal cylinder 501 is hinged to the support seat 1 through the second bearing seat 503, and the shaft of the second bearing seat 503 extends in the horizontal direction. Specifically, under the action of the horizontal cylinder 501, the cylinder connecting plate 401 can drive the sealing disc 3 to move along the horizontal linear slide rail 2 from the center of the mixing pot 01 to the rear of the bottom discharge mixing mixer to the maximum position, so that the machine can perform the discharge action. After the discharge is completed, under the action of the horizontal cylinder 501, the cylinder connecting plate 401 drives the sealing disc 3 to move along the horizontal linear slide rail 2 from the center of the mixing pot 01 to the front of the bottom discharge mixing mixer to the maximum position. Since the front end of the support seat 1 is provided with a cleaning port 102, the sealing disc 3 can be exposed in a certain area, which facilitates cleaning.
[0034] In this embodiment, the discharge channel 101 is a cylindrical channel, and the upper opening of the discharge channel 101 is a frustum-shaped opening; the sealing disc 3 is a frustum structure and matches the upper opening of the discharge channel 101. When the piston rod of the vertical cylinder 402 drives the sealing disc 3 to move upward to the upper opening of the discharge channel 101, the sealing disc 3 can block the upper opening of the discharge channel 101.
[0035] The usage process of the movable sealing device for the bottom-discharge mixing mixer provided in this embodiment is as follows:
[0036] In use, align the discharge channel 101 at the front end of the support base 1 with the discharge port of the mixing pot 01 of the bottom discharge mixer. First, drive the up and down moving mechanism 4 to slide forward along the two horizontal linear slide rails 2 at the front end of the support base 1 through the forward and backward moving mechanism 5 until the up and down moving mechanism 4 is located close to the discharge channel 101. Then, drive the sealing plate 3 to move upward through the up and down moving mechanism 4 to seal the discharge channel 101.
[0037] When material needs to be discharged, the sealing disc 3 is first moved downward by the up-and-down moving mechanism 4, and then the up-and-down moving mechanism 4 is moved backward along the two horizontal linear slide rails 2 at the front end of the support base 1 by the front-back moving mechanism 5, until the up-and-down moving mechanism 4 is located away from the discharge channel 101. Figure 2As shown, this allows the material inside the mixing pot 01 to fall smoothly from the discharge channel 101 without affecting the subsequent transportation of the falling material.
[0038] When the sealing disc 3 needs to be cleaned, the forward and backward moving mechanism 5 drives the up and down moving mechanism 4 to move forward along the two horizontal linear slide rails 2 at the front end of the support base 1 until the up and down moving mechanism 4 is located near the cleaning port 102 at the front end of the support base 1. Figure 3 As shown, the sealing disc 3 is exposed through the cleaning port 102, which makes the subsequent cleaning of the material adhering to the sealing disc 3 simple and easy to operate.
[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
