Description

Technical Field

[0001] This utility model relates to the field of candy production technology, specifically a candy sorting and screening machine with foreign object recognition. Background Technology

[0002] Candy screening machines are used in various candy production lines to screen candies of different particle sizes. They are key equipment for removing defective products and ensuring the quality of candy production.

[0003] In the existing technology, most candy screening machines adopt linear screening machines, which are usually composed of a frame, a vibrating motor, a screening chamber and a screen. The vibrating motor drives the screening chamber to vibrate, which in turn drives the screen to vibrate, so that candy or other impurities with a particle size smaller than the mesh size can fall off the screen, thus achieving the purpose of screening candy.

[0004] However, most existing candy sorting machines typically have a fixed number of screen layers. When the screen has only a single layer, the equipment can only be used for sorting one particle size specification. When the screen has multiple layers, the mesh size usually decreases from top to bottom, and candy can only fall from the top screen to the bottom. If the user only wants to start filtering from the bottom screens with smaller mesh sizes, the equipment cannot meet the sorting requirements. Clearly, existing candy sorting machines have certain limitations and are difficult to adapt to various sorting needs. Therefore, this invention proposes a candy sorting machine with foreign object recognition to effectively solve the above-mentioned drawbacks. Utility Model Content

[0005] The purpose of this invention is to provide a candy sorting and screening machine with foreign object recognition, which solves the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a candy sorting machine with foreign object recognition, including a sorting chamber, the sorting chamber having a main inlet and a main outlet, a foreign object recognition module fixedly installed at the main outlet, the main inlet including a first inlet and a second inlet opened at the top of the sorting chamber, a first screen and a second screen arranged sequentially from top to bottom in the sorting chamber, the aperture of the first screen being larger than that of the second screen, and the second screen being detachably installed in the sorting chamber; When the candy enters the screening chamber from the first feed inlet, the candy passes through the first screen and the second screen in sequence. When the candy enters the screening chamber from the second feed inlet, the candy is only screened by the second screen.

[0007] Optionally, a first partition, a second partition, and a third partition are fixedly arranged sequentially along the length of the screening chamber. The first feed inlet is formed by the second and third partitions, and the second feed inlet is formed by the first and second partitions. A feed hopper is slidably arranged on the top of the screening chamber along its length. The widths of the first and second feed inlets are equal to the width of the bottom opening of the feed hopper. Symmetrically distributed baffles are fixed on the left and right sides of the bottom of the feed hopper, and the width of the baffles is not less than the width of the first or second feed inlet.

[0008] Optionally, spring beads are fixedly provided on the top of the first partition and the top of the third partition, and through holes for the spring beads to be inserted are provided on both partitions.

[0009] Optionally, the second partition is L-shaped, the first screen is fixedly installed on the bottom plate of the second partition, and the second screen is detachably connected to the first partition.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 5 This application proposes a candy sorting machine with foreign object recognition, including a sorting chamber 1. The sorting chamber 1 has a main inlet and a main outlet. A foreign object recognition module 7 is fixedly installed at the main outlet. The foreign object recognition module 7 includes a color CCD camera or metal detector fixedly installed at several outlets, and a PLC controller electrically connected to the color CCD camera or metal detector. This allows the foreign object recognition module 7 at different outlets to photograph or detect metal in the candies at different outlets, thereby assisting workers in quickly determining which outlet contains foreign objects. This facilitates the collection of candies with foreign objects for further sorting, or the removal of foreign objects manually.

[0019] The system includes a color CCD camera (model BFS-U3-04S2C-CS) with 720×540 pixels, responsible for capturing images of the candy surface and identifying foreign objects with color differences, such as black plastic, hair, and adhering fragments. A metal detector (model FMD4012) with a sensing accuracy of at least 0.5mm metal uses a high-frequency oscillating probe to identify metal impurities such as iron powder from equipment wear and aluminum foil fragments. The PLC controller has a data analysis and processing module that processes and analyzes the received signals and displays the detection results on a screen for staff to view. The color CCD camera and metal detector can also be used together to identify and detect even more foreign objects.

[0020] Furthermore, the main feed inlet includes a first feed inlet 101 and a second feed inlet 102 located at the top of the screening chamber 1. Inside the screening chamber 1, a first screen 2 and a second screen 3 are arranged sequentially from top to bottom. The aperture of the first screen 2 is larger than that of the second screen 3, and the second screen 3 is detachably installed inside the screening chamber 1. The first screen 2 and the second screen 3 can filter candies with particle sizes smaller than the aperture to the bottom of the screening chamber 1, and also allow small foreign objects mixed within the candies to fall to the bottom, thus achieving the purpose of removing foreign objects.

[0021] Furthermore, when the candy enters the screening chamber 1 through the first inlet 101, it passes through the first screen 2 and the second screen 3 sequentially, allowing the candy to pass through multiple layers of screening from the top down. When the candy enters the screening chamber 1 through the second inlet 102, it only passes through the second screen 3, bypassing the first screen 2. After the second screen 3 is removed, the candy enters the screening chamber 1 through the first inlet 101 again, passing through only the first screen 2.

[0022] The second screen 3 can be disassembled and replaced with screens of different aperture sizes, further improving the applicability of the equipment to meet more screening needs.

[0023] Specifically, a first partition 103, a second partition 104, and a third partition 105 are fixedly arranged sequentially along the length of the screening chamber 1, and all three partitions extend along the height of the screening chamber 1. The first inlet 101 is formed by the second partition 104 and the third partition 105, and the second inlet 102 is formed by the first partition 103 and the second partition 104. A feeding hopper 4 is slidably arranged on the top of the screening chamber 1 along its length. The size of the first inlet 101 is the same as the size of the second inlet 102, and the size of the bottom opening of the feeding hopper 4 is the same as the size of the first inlet 101 and the second inlet 102, so that when the bottom opening of the feeding hopper 4 is aligned with the first inlet 101 or the second inlet 102, the candy can enter the screening chamber 1 from different feeding hoppers.

[0024] To prevent candy from splashing into the wrong inlet when it enters from one inlet, this application provides symmetrically distributed baffles 401 on the left and right sides of the bottom of the feed hopper 4. The width of the baffles 401 is not less than the width of the first inlet 101 or the second inlet 102. This allows the baffles 401 to block and close the first inlet 101 or the second inlet 102 when the feed hopper 4 moves on top of the screening chamber 1, thereby preventing candy from splashing into the wrong inlet.

[0025] The bottom of the feed hopper 4 and the baffle 401 are slidably connected to the top edge of the screening chamber 1 along the length of the screening chamber 1, and the bottom of the feed hopper 4 and the baffle 401 are in contact with the top of the first partition 103, the second partition 104 and the third partition 105.

[0026] On the other hand, spring-loaded balls 5 are fixedly installed on the top of the first partition 103 and the top of the third partition 105, and through holes for the spring-loaded balls 5 are opened on both baffles 401. The movable end of the spring-loaded ball 5 can elastically extend and retract vertically. When the through hole on the baffle 401 and the spring-loaded ball 5 are aligned, the movable end of the spring-loaded ball 5 can pop up under the action of the spring, thereby passing through the through hole to limit the baffle 401, preventing the feed hopper 4 and the baffle 401 from sliding on the top of the screening chamber 1, and thus completing the blocking operation of the first feed port 101 or the second feed port 102.

[0027] In this embodiment, the second partition 104 is L-shaped, the first screen 2 is fixedly installed on the bottom plate of the second partition 104, and the second screen 3 is detachably connected to the first partition 103. The outer fixing frame of the first screen 2 is provided with a rectangular frame, which is fixedly connected to the second partition 104 and the side wall of the screening chamber 1 by screws, bolts and other connecting parts, so that the first screen 2 can be stably installed in the screening chamber 1.

[0028] Furthermore, the outer fixed frame of the second screen 3 is provided with an installation frame 301, and the first partition 103 is provided with a through opening for the second screen 3 and the installation frame 301 to pass through along the length of the screening chamber 1, so that the second screen 3 and the installation frame 301 can be disassembled and assembled from the side close to the first partition 103.

[0029] like Figure 4 As shown, the side of the mounting frame 301 away from the discharge port of the screening chamber 1 is fixedly and detachably connected to the first partition 103. Mounting plates are fixedly installed on the upper and lower sides of the mounting frame 301. Circular holes are opened on the mounting plates. Threaded holes are opened on the first partition 103 directly opposite the circular holes. The sizes of the circular holes and the threaded holes are matched. Bolts are inserted into both the circular holes and the threaded holes to fix the mounting plates to the first partition 103, thus completing the installation operation of the mounting frame 301, and then completing the installation operation of the second screen 3.

[0030] Furthermore, a disassembly port 106 is provided on the side of the screening chamber 1 away from the discharge port, through which the second screen 3 and the mounting frame 301 can be disassembled and assembled. The disassembly port 106 is connected to a chamber door via a hinge. After opening the chamber door, the second screen 3 and the mounting frame 301 inside the screening chamber 1 can be disassembled. After pulling the second screen 3 and the mounting frame 301 out from the disassembly port 106, screens of different aperture sizes can be replaced.

[0031] To ensure greater stability of the second screen 3 and the mounting frame 301 within the screening chamber 1, this application includes a slide rail 6 fixedly installed on the side wall of the screening chamber 1 for the mounting frame 301 to slide along the length of the screening chamber 1. The slide rail 6 has a groove on its inner side that matches the shape of the mounting frame 301. The two side frames of the mounting frame 301 slide into the groove, and the slide rail 6 supports the mounting frame 301 to ensure the stability of the second screen 3.

[0032] It should be noted that the main discharge outlet includes a first discharge outlet 107, a second discharge outlet 108, and a third discharge outlet 109. The first discharge outlet 107 is connected to the first inlet 101, the second discharge outlet 108 is connected to the second inlet 102, and the third discharge outlet 109 is connected to the cavity between the second screen 3 and the bottom wall of the screening chamber 1. Therefore, candies on the first screen 2 will fall from the first discharge outlet 107, candies on the second screen 3 will fall from the second discharge outlet 108, and candies at the bottom of the screening chamber 1 will fall from the third discharge outlet 109, facilitating the collection of candies of different particle sizes by the staff.

[0033] The working principle and usage process of this utility model are as follows: When only single-layer screening is required, the candy is poured into the screening chamber 1 from the second inlet 102, and the candy only passes through the second screen 3. By replacing the second screen 3 with different aperture sizes, more screening needs can be met. Alternatively, the second screen 3 can be disassembled, and the candy can be poured into the first inlet 101, in which case the candy only passes through the first screen 2. When multi-layer screening is required, the second screen 3 is installed in the screening chamber 1, and the candy is poured into the first inlet 101, so that the candy can pass through the first screen 2 and the second screen 3 for multi-layer screening.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
