Description

Technical Field

[0001] The utility model relates to a multi-channel material screening mechanism, which is used for material screening and flow diversion in a vacuum secondary packaging process. Background Art

[0002] From the current market perspective, vacuum secondary packaging requires hardness screening of vacuum materials, and the mainstream implementation methods can be roughly divided into two types, which are temporarily referred to as "pressing type" and "limited width type". The pressing type is to apply a certain pressure to the material to observe whether it is deformed, so as to distinguish between soft and hard. There are various ways to apply pressure, but considering that excessive pressure will leave marks on the material, materials with unclear soft and hard characteristics are often not screened out. The pressing type generally has a larger volume after including the screening mechanism. The limited width type achieves screening through a conveyor line with a left and right side conveyor belt clamping the material to provide power, and an unsupported bottom. Whenever the material width is less than the preset width, the conveyor belts on both sides fail to effectively clamp the material to provide friction, and the material falls naturally. However, the rejection rate is often artificially high due to the natural error of the material width. Utility Model Content

[0028] The soft bag detection component of the utility model basically adopts the pressing type. Different from the common pressing type, its pressure is divided into two parts. The first part is the large-area pressure of the material clamping plate, which does not require pressure, but is more for determining the reference and positioning the material; the second part is the telescopic top column pressing, which has a relatively large pressure. The telescopic top column adopts a rubber head, which does not cause much damage to the material. In addition, this mechanism adds a lifting platform and a straight conveyor belt as a screening method, so that there are more choices for the flow direction of the material.

[0029] In the embodiment of the utility model, the lifting platform is arranged above the straight conveyor belt, and the lifting platform is driven to rise and fall by the first cylinder 7, so that the feed side of the lifting platform is connected with or disconnected from the discharge end of the feed conveyor belt.

[0030] In the embodiment of the utility model, the first cylinder is arranged at both ends of the lifting platform, the double piston rods of the first cylinder are fixedly connected to the lifting platform upward, and the cylinder body of the first cylinder is installed on the external frame.

[0031] In the embodiment of the utility model, the straight-through conveyor belt is installed on a conveyor belt frame 8, and the end side of the conveyor belt frame away from the feed conveyor belt is hinged on an external frame. The end side of the conveyor belt frame close to the feed conveyor belt is driven to swing by a second cylinder 9 serving as a driving component to connect or disconnect the feed side of the straight-through conveyor belt with the discharge end of the feed conveyor belt.

[0032] In the embodiment of the utility model, the piston rod of the second cylinder is hinged on the conveyor frame, and the cylinder body of the second cylinder is hinged on the external frame.

[0033] In an embodiment of the utility model, the feed conveyor belt is arranged for horizontal transmission.

[0034] In the embodiment of the utility model, the soft bag detection assembly includes a fixed frame 10 located above the feed conveyor belt, and an open clamp cylinder 11 is fixedly connected to the fixed frame. The material clamp has two pieces and is respectively fixedly connected to the piston rods at both ends of the open clamp cylinder.

[0035] In the embodiment of the utility model, there are two material clamping plates and they are located above the feed conveyor belt, and the two material clamping plates are arranged opposite to each other.

[0036] In the embodiment of the utility model, the telescopic push column is arranged on one of the material clamping plates, which is provided with a push column clearance hole 12, and a telescopic cylinder 13 for detection is fixedly connected to the non-clamping surface side of the material, and the push column is fixedly connected to the piston rod of the telescopic cylinder for detection.

[0037] In the embodiment of the utility model, the top column adopts a cylindrical rubber head.

[0038] In the embodiment of the utility model, the working principle of the multi-channel material screening mechanism is:

[0039] 1. By Figure 1-Figure 3 visible, Figure 1-Figure 3 These are the three working modes of the organization. Figure 1 In the general working mode, the inspected materials enter the lifting platform and go to the upper level for packaging. Figure 2 The rejection mode is required for screening out materials. At this time, unqualified materials fall into the straight conveyor belt, and the straight conveyor belt briefly reverses (counterclockwise) to send the materials under the feed conveyor belt. Figure 3In the straight-through conveying mode, the straight-through conveyor belt connects to the feed conveyor belt, and the straight-through conveyor belt rotates forward (clockwise). The material passes through the equipment directly. Products that do not require secondary bagging skip this process and directly enter the next process on the production line. At this time, the material does not need to be screened, and there is no problem of the screening function being occupied.

[0040] 2. Principle of soft package detection component: Figure 4 and Figure 5 Represent the retracted and extended states respectively. Figure 7 As shown, the open clamp cylinder and the detection telescopic cylinder on the air path are connected in parallel and act synchronously. When the open clamp is clamped, the top column extends together. At this time, if there is no obstruction, the top column will exceed the material clamping surface. When the open clamp is opened, the top column retracts together, and at this time, the top column retracts to within the material clamping surface. When there is material 14 and the material hardness is sufficient, the top column will be flush with the material clamping surface, and the detection telescopic cylinder moves to a fixed stroke position. Only at this moment can the material be judged as qualified.

[0041] 3. If Figure 7 It can be seen that the pressure of the opening clamp cylinder and the telescopic cylinder for testing are adjusted synchronously, and the diameter of the opening clamp cylinder is slightly larger than that of the telescopic cylinder for testing, which can ensure that the top column will not push the opening clamp cylinder in the opposite direction. And according to the material hardness testing standard, the pressure regulating table can be adjusted to meet different hardness requirements.

[0042] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms.
