Description

Technical Field

[0001] This utility model relates to the field of bread sieving machine technology, specifically a new type of toast bread sieving machine that prevents dust from scattering. Background Technology

[0002] Bread making sieving machines are mainly used for flour impurity removal, grading, and breadcrumb screening. There are various types of existing equipment, and the selection should be based on production needs. Flour impurity removal sieves are used to remove foreign objects such as threads and insect eggs from flour. 10-40 mesh screens are commonly used. The combination of drum and air classifier models reduces breadcrumb damage and improves output and quality through double screening drums and dust collection boxes.

[0003] For small-volume dusty materials, most screening machines currently lack shielding devices, causing dust to spill out during the screening process and affecting air quality.

[0004] To overcome the above-mentioned defects, existing technology (Chinese Patent No. CN112620066A, Publication Date: 2021-04-09) discloses a screening machine and screening method to prevent dust spillage. A bag containing material is placed with its opening facing downwards into the feed hood. The material enters the screening cylinder along the feed hood. A baffle plate is rotated around a second rotating shaft and fixed above the feed hood, thus closing the upper opening of the screening cylinder and preventing dust from spilling out of the screening cylinder during the screening process. The material overflows from above. The motor drives the screening cylinder to rotate. The filter screen is installed on the side of the screening cylinder. Centrifugal force is used to throw out small-volume materials. After screening is completed, before the next screening, the pull plate is pulled outward and the fan is started to blow air inward, blowing the residual dust to the outside of the screening cylinder and spraying it out through the discharge port. A collection bag is installed below the discharge port. When the cover is opened, the cover will drive the air to flow outward, preventing the residual dust in the screening cylinder from overflowing outward with the airflow.

[0005] While the above design can solve the aforementioned problems, the existing design lacks sufficient sieving capabilities for flour, resulting in low sieving efficiency and requiring manual collection, which reduces the intelligence and efficiency of the equipment. Furthermore, dust is generated during processing, creating a poor processing environment that affects worker health, and the inability to monitor the processing status of the equipment further hinders its ease of use.

[0006] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0007] The main objective of this invention is to provide a novel sieving machine for toast bread that prevents dust dispersion, thereby addressing the shortcomings in the existing flour sieving design mentioned in the background art. These shortcomings result in low sieving efficiency and the need for manual collection, reducing the intelligence and efficiency of the equipment. Furthermore, dust dispersion occurs during processing, creating a poor processing environment that affects worker health, and the inability to monitor the processing status further hinders the ease of use of the equipment.

[0008] To achieve the above objectives, the solution of this utility model is: a novel sieving machine for toast bread that prevents dust dispersion, comprising a bottom support frame, a rotating drive block installed inside the bottom support frame, and a sliding sieving mechanism for swinging the bottom receiving box installed above the rotating drive block. The sliding sieving mechanism includes a first swing plate, which is fixedly installed on the outer surface of the output end of the rotating drive block. A first sliding inner groove is provided on the upper surface of the bottom support frame, and a transmission dustproof mechanism for external protection of the dust screen is installed inside the first sliding inner groove.

[0009] Furthermore, the transmission dustproof mechanism includes a protective support frame, and the bottom of the protective support frame is slidably installed inside the first sliding inner groove. A dustproof fan is installed on the top of the protective support frame, and the lower working position of the dustproof fan corresponds to the installation position of the dust screen.

[0010] Furthermore, a contact rotating plate is installed on the side of the protective support frame, and a reset contraction spring is installed on the side of the contact rotating plate. The moving trajectory of the contact rotating plate is in contact with the dust screen, and a rotating support frame is installed on the upper surface of the bottom support frame.

[0011] Furthermore, a connecting rod is installed inside the other end of the first swing plate, and a corresponding sliding block is installed inside the other end of the bottom support frame. The corresponding end of the connecting rod is rotatably installed on the side of the corresponding sliding block, and elastic moving parts are installed at both ends of the inner surface of the bottom support frame.

[0012] Furthermore, the elastic moving parts are respectively fixedly installed on the outer surfaces of the rotating drive block and the corresponding sliding block, and a bottom receiving box is installed on the top of the corresponding sliding block, a bottom receiving box is installed on the top of the rotating drive block, and a dust screen is installed on the top of the rotating drive block.

[0013] Furthermore, the bottom support frame has second sliding inner grooves on its left and right sides, and the dust screen slides laterally along the inside of the second sliding inner groove. The installation position of the bottom receiving box corresponds to the lower screening position of the dust screen, and the two sides of the dust screen contact the inner surface of the second sliding inner groove to form a sliding structure.

[0014] Furthermore, the rotating support frame is equipped with a fitting swing plate inside, and the inner surface of the protective support frame is equipped with fitting and bonding frames on both sides. The end of the fitting swing plate is nested inside the fitting and bonding frame, and the upper surface of the bottom support frame is equipped with a magnetic fastener.

[0015] Compared with the prior art, the beneficial effects of this utility model are: When the new type of toast bread sieving machine that prevents dust dispersion needs to sieve the flour, the rotating drive block is directly started and the corresponding sliding block is driven through the first swing plate and the connecting rod. At this time, the rotating drive block and the corresponding sliding block will drive the dust screen and the bottom receiving box to slide through the elastic moving part. This design makes the equipment better for sieving flour, improves the sieving efficiency, and eliminates the need for manual collection, thus improving the intelligence and efficiency of the equipment.

[0016] Furthermore, when it is necessary to perform dust prevention operations on the outside of the dust screen, the oscillating plate is pressed down directly to make the protective support frame slide in a limited position until the dust fan moves above the dust screen. At this time, the position of the protective support frame is exactly connected and fixed with the magnetic fastener. This design prevents dust from scattering, improves the processing environment, and allows for observation of the processing status of the equipment, thus improving the ease of use of the equipment.

[0017] Furthermore, the installation position of the bottom receiving box corresponds to the position below the dust screen. During the sliding process, finer flour can be screened and fall into the bottom receiving box. This design makes the use of the equipment more intelligent and convenient.

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] 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.

[0027] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: a novel sieving machine for toast bread that prevents dust dispersion, comprising a bottom support frame 1, a rotating drive block 12 installed inside the bottom support frame 1, and a sliding sieving mechanism for swinging the bottom receiving box 17 installed above the rotating drive block 12, such as... Figure 3 As shown, the sliding screening mechanism includes a first swing plate 13, which is fixedly installed on the outer surface of the output end of the rotating drive block 12. The upper surface of the bottom support frame 1 is provided with a first sliding inner groove 2, and a transmission dustproof mechanism for external protection of the dust screen 16 is installed inside the first sliding inner groove 2.

[0028] like Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the shortcomings of existing flour sieving designs, which result in low sieving efficiency and the need for manual collection, reducing the intelligence and efficiency of the equipment. It discloses the following: a connecting rod 14 is installed inside the other end of the first swing plate 13, and a corresponding sliding block 15 is installed inside the other end of the bottom support frame 1. The corresponding end of the connecting rod 14 is rotatably mounted on the side of the corresponding sliding block 15. Elastic moving parts 11 are installed at both ends of the inner surface of the bottom support frame 1, and are respectively fixedly mounted on the outer surfaces of the rotating drive block 12 and the corresponding sliding block 15. A bottom receiving box 17 is installed on the top of the corresponding sliding block 15. Figure 4 As shown, a bottom receiving box 17 is installed on the top of the rotating drive block 12, and a dust screen 16 is installed on the top of the rotating drive block 12. The left and right sides of the bottom support frame 1 are provided with second sliding inner grooves 18, and the left and right sides of the dust screen 16 slide laterally along the inside of the second sliding inner groove 18. The installation position of the bottom receiving box 17 corresponds to the lower screening position of the dust screen 16, and the two sides of the dust screen 16 contact the inner surface of the second sliding inner groove 18 to form a sliding structure.

[0029] When flour needs to be sifted, the flour is placed directly into the dust sieve 16. The rotating drive block 12, nested inside the bottom support frame 1, is then activated. This rotation drives the first swing plate 13, fixed externally at the output end, to rotate. The rotation of the first swing plate 13 then synchronously drives the connecting rod 14, which is also rotatably mounted at the other end. Since the other end of the connecting rod 14 is nested and rotatably mounted on both sides of the corresponding sliding block 15, the corresponding sliding block 15 will slide laterally along the bottom support frame 1 in a limited manner. When the connecting rod 14 drives the rotating drive block 12 and the corresponding sliding block 15, as... Figure 4 As shown, the rotating drive block 12 and the corresponding sliding block 15 will press against the elastic moving part 11 fixedly installed at the corresponding position inside the bottom support frame 1 to generate a contraction operation. During the sliding process of the rotating drive block 12, the dust screen 16 fixedly installed at the top will be driven synchronously. The sliding operation of the dust screen 16 will be limited to sliding along the second sliding inner groove 18 opened at the corresponding positions on both sides of the bottom support frame 1. At the same time, the movement of the corresponding sliding block 15 can synchronously drive the bottom receiving box 17 fixedly installed at the top. During this process, the flour placed inside the dust screen 16 can be sieved. During this process, the finer flour can fall into the bottom receiving box 17 for collection. This design makes the use of the equipment more convenient and efficient.

[0030] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown addresses the problems of dust dispersion during equipment processing, resulting in a poor processing environment that affects worker health and hindering ease of use due to the inability to monitor the processing status. It discloses a dustproof transmission mechanism including a protective support frame 3, with the bottom of the protective support frame 3 slidably installed inside a first sliding inner groove 2. A dustproof fan 4 is installed on the top of the protective support frame 3, with the lower working position of the dustproof fan 4 corresponding to the installation position of the dust screen 16. An abutment rotating plate 5 is installed on the side of the protective support frame 3. Figure 5As shown, a reset spring 6 is installed on the side of the contact rotating plate 5, the moving trajectory of the contact rotating plate 5 is in contact with the dust screen 16, and a rotating support frame 7 is installed on the upper surface of the bottom support frame 1. A fitting swing plate 8 is installed inside the rotating support frame 7, and fitting and attaching frames 10 are installed on both sides of the inner surface of the protective support frame 3. The end of the fitting swing plate 8 is nested inside the fitting and attaching frame 10, and a magnetic fixing member 9 is installed on the upper surface of the bottom support frame 1.

[0031] When the dust screen 16 is performing sliding sieving, the flour placed inside will scatter. At this time, during the rotation of the drive block 12, it directly presses down on the fitting swing plate 8. The fitting swing plate 8 can then rotate within the rotating support frame 7 fixedly installed on the upper surface of the bottom support frame 1. Since the end of the fitting swing plate 8 is nested inside the fitting and bonding frame 10, and the fitting and bonding frame 10 is fixedly installed on the inner surface of the protective support frame 3, as the fitting swing plate 8 rotates, as... Figure 6 As shown, the protective support frame 3 can be driven to slide laterally along the first sliding inner groove 2 opened on the upper surface of the bottom support frame 1. During the sliding process of the protective support frame 3, the abutting rotating plate 5 will be driven synchronously until the abutting rotating plate 5 abuts against the outside of the dust screen 16. At this time, the dust screen 16 can rotate along the inside of the top of the protective support frame 3 until the protective support frame 3 slides to the corresponding position of the magnetic fixing part 9 fixedly installed above the bottom support frame 1 to complete the fixing work. At this time, after the abutting rotating plate 5 loses its abutment, the reset contraction spring 6 fixedly installed at the top will rebound and reset in the opposite direction. At this time, the protective support frame 3 and the abutting rotating plate 5 can completely protect the outside of the dust screen 16. In addition, the dustproof fan 4 installed inside the top of the protective support frame 3 will rotate the flour to prevent dust during the processing. This design makes the use of the equipment more intelligent and stable.

[0032] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
