Description

Technical Field

[0001] This utility model relates to the field of flip-plate drying, and in particular to a multi-layer flip-plate drying device. Background Technology

[0002] Tilting dryer, also known as multi-layer conveyor dryer, uses tilting plates to carry materials. The tilting plates move periodically and flip over to unload the materials onto the next tilting plate. During this process, heated air introduced by the blower penetrates the material layer, allowing the moisture in the material to evaporate.

[0003] Existing technologies, such as the utility model patent with announcement number CN2569063Y, disclose a tracked flip-plate type low-temperature dryer. This patent includes a casing with an air inlet, an air outlet, a material inlet, and a material outlet. The casing contains a multi-layer tracked flip-plate device. This device includes a rotatable sprocket and a track driven by the sprocket. The track includes a belt base that connects the flip-plates in series and flip-plates hinged to the belt base. The flip-plates have through holes. This machine is used in conjunction with a hot air furnace. The drying platform consists of chain-driven tracked flip-plates with mesh, arranged in multiple layers for reciprocating movement. The compact structure allows for a long material path within the machine with minimal impact, effectively reducing the temperature of the hot air furnace, decreasing material breakage, and minimizing dust pollution.

[0004] The inventors discovered the following problems during the use of multi-layer flip-plate dryers in their daily work: When wet materials (especially those with a certain degree of stickiness or that are prone to absorbing moisture and clumping) are conveyed to the feeding frame by the feeding device and fall into the drying chamber, they are very prone to blockage, bridging, or adhesion in the feeding frame channel. Blockage of materials at the feeding frame will directly interrupt the continuity of the drying process, resulting in uneven material distribution on the upper flip-plate, and even causing the equipment to run idle or overload, which seriously affects the drying efficiency and product quality stability. Traditional solutions often rely on manual intervention, such as poking and stirring with sticks after the machine is stopped. This not only increases the labor intensity and safety hazards of the operators, but also significantly reduces the production efficiency of the equipment due to frequent shutdowns. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where wet materials easily clog the feed frame, affecting the drying effect and reducing work efficiency.

[0006] To solve the above technical problems, this utility model provides a multi-layer flip-plate drying device, including: a flip-plate drying box, a driving mechanism installed on the lower surface of the flip-plate drying box, an air inlet fan installed on one side of the flip-plate drying box, an air collecting device installed on the upper surface of the flip-plate drying box, a feeding device installed on the side of the flip-plate drying box away from the air inlet fan, a feeding frame fixedly connected to the upper surface of the flip-plate drying box corresponding to the position of the feeding device, a discharging frame fixedly connected to the lower surface of the flip-plate drying box, an adjusting structure provided on the upper surface of the flip-plate drying box corresponding to the position of the feeding frame, the adjusting structure including a fixed frame, the fixed frame being fixedly connected to the flip-plate drying box, a screw rotatably connected to the inner wall of the fixed frame, a servo motor fixedly connected to one side of the fixed frame, the output end of the servo motor being fixedly connected to the screw, and a support frame threadedly connected to the arc surface of the screw. The inner wall of the support frame is slidably connected to the inner wall of the fixed frame. A round rod is fixedly connected to the inner wall of the support frame, and the arc surface of the round rod is slidably connected to the support frame. Two support rods are fixedly connected to the inner wall of the support frame, and a support plate is slidably connected to the arc surfaces of the two support rods. The support plate is slidably connected to the inner wall of the support frame. An installation frame is fixedly connected to the side of the support plate away from the support frame. An installation rod is slidably connected to the upper surface of the installation frame. A spring is fitted onto the arc surface of the installation rod, and both ends of the spring are fixedly connected to the installation rod and the installation frame, respectively. A connecting rod is slidably connected to the inner wall of the installation frame. An installation hole is opened at the end of the connecting rod near the installation frame, and the inner wall of the installation hole is engaged with the installation rod. An adjustment groove is opened at the side of the feed frame near the fixed frame, and the inner wall of the adjustment groove is slidably connected to the connecting rod. An agitator is fixedly connected to the end of the connecting rod away from the installation frame.

[0007] The effect achieved by the above components is as follows: the servo motor drives the screw to rotate, which in turn moves the support frame horizontally, thereby causing the connecting rod and the stirring block to reciprocate along the adjusting groove, stirring the material in the feeding frame, effectively preventing material blockage and ensuring smooth feeding.

[0008] Preferably, the stirring block has a pointed cone shape around its perimeter, and the stirring block is specifically a hollow stainless steel block.

[0009] The effects achieved by the above components are as follows: the pointed cone design makes it easier for the agitator to cut into and disperse materials, improving agitation efficiency; the hollow stainless steel structure reduces the weight of the agitator, reduces the driving load, and at the same time has corrosion resistance and durability, making it suitable for humid environments.

[0010] Preferably, a protective shell is fixedly connected to one side of the mounting bracket at the position corresponding to the servo motor.

[0011] The above components achieve the following effects: the protective shell can effectively protect the servo motor from dust, moisture or external impact, extend the motor's service life, and ensure the stable operation of the adjustment structure.

[0012] Preferably, the upper end of the mounting rod is rotatably connected to a pull ring, which is specifically a stainless steel ring.

[0013] The effects achieved by the above components are as follows: the pull ring design makes it easy for the operator to manually pull the mounting rod, simplifying the disassembly and installation process; the stainless steel ring is wear-resistant and corrosion-resistant, improving durability and ease of operation.

[0014] Preferably, the lower end of the mounting rod is arc-shaped.

[0015] The effect achieved by the above components is that the arc-shaped lower end makes it easier to align the mounting rod with and insert it into the mounting hole of the connecting rod, reducing jamming and wear, and ensuring a firm connection and smooth operation.

[0016] Preferably, a roller is rotatably connected to the arc surface of the connecting rod at the position corresponding to the adjustment groove, and the roller is slidably connected to the inner wall of the adjustment groove, wherein the adjustment groove is a corrugated groove.

[0017] The effects achieved by the above components are as follows: the rollers and corrugated grooves work together to reduce the frictional resistance when the connecting rod moves, making the horizontal and vertical reciprocating motion smoother; the corrugated groove design converts the horizontal motion into vertical motion, enhances the mixing effect of the agitator, and prevents the material from clumping.

[0018] Preferably, a curtain sleeve is fixedly connected to the upper surface of the feeding frame, and the end of the curtain sleeve away from the feeding frame is fixedly connected to the feeding device.

[0019] The effects achieved by the above components are: the curtain sleeve can effectively seal the connection between the feed frame and the feeding device, prevent material leakage and contamination, maintain a dry environment, and improve the hygiene and operating efficiency of the equipment.

[0020] Compared with related technologies, the multi-layer flip-plate drying equipment provided by this utility model has the following beneficial effects: This utility model provides a multi-layer flip-plate drying device. Through an adjustable structure, a servo motor drives a screw to rotate, causing the support frame and connecting rod to perform regular horizontal and vertical compound movements along a corrugated adjusting groove. This results in the stirring block forming multi-dimensional reciprocating agitation within the feeding frame, effectively breaking up any material arches or adhered clumps, ensuring continuous and uniform feeding. This automatic anti-clogging mechanism significantly reduces downtime for cleaning due to blockages, improving the overall operating efficiency and capacity of the drying equipment. Furthermore, the structure features a quick-release module; simply pulling the installation rod releases the fixing of the connecting rod, facilitating the removal of the stirring block from the feeding frame for replacement or maintenance. This greatly reduces the difficulty and time cost of maintenance, ensuring long-term stable production capacity. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 4 This utility model provides a multi-layer flip-plate drying device, comprising: a flip-plate drying box 1, a drive mechanism 2 installed on the lower surface of the flip-plate drying box 1, an air inlet fan 3 installed on one side of the flip-plate drying box 1, an air collecting device 4 installed on the upper surface of the flip-plate drying box 1, a feeding device 5 installed on the side of the flip-plate drying box 1 away from the air inlet fan 3, a feeding frame 6 fixedly connected to the upper surface of the flip-plate drying box 1 at the position corresponding to the feeding device 5, a discharging frame 7 fixedly connected to the lower surface of the flip-plate drying box 1, and an adjustment structure 8 provided on the upper surface of the flip-plate drying box 1 at the position corresponding to the feeding frame 6.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 4The adjusting structure 8 includes a fixed frame 801, which is fixedly connected to the flip-plate drying box 1. A screw 802 is rotatably connected to the inner wall of the fixed frame 801. A servo motor 803 is fixedly connected to one side of the fixed frame 801, and the output end of the servo motor 803 is fixedly connected to the screw 802. A support frame 805 is threadedly connected to the arc surface of the screw 802. The support frame 805 is slidably connected to the inner wall of the fixed frame 801. A round rod 806 is fixedly connected to the inner wall of the support frame 805, and the arc surface of the round rod 806 is slidably connected to the support frame 805. Two support rods 807 are fixedly connected to the inner wall of the support frame 805. A support plate 808 is slidably connected to the arc surface of the 07 support frame 805. The support plate 808 is slidably connected to the inner wall of the support frame 805. A mounting frame 809 is fixedly connected to the side of the support plate 808 away from the support frame 805. A mounting rod 810 is slidably connected to the upper surface of the mounting frame 809. A spring 811 is sleeved on the arc surface of the mounting rod 810. The two ends of the spring 811 are fixedly connected to the mounting rod 810 and the mounting frame 809, respectively. A connecting rod 813 is slidably connected to the inner wall of the mounting frame 809. A mounting hole 814 is opened at the end of the connecting rod 813 near the mounting frame 809. The inner wall of the mounting hole 814 is engaged with the mounting rod 810. The feed frame 6 is close to... An adjustment groove 815 is provided on one side near the fixed frame 801. The inner wall of the adjustment groove 815 is slidably connected to the connecting rod 813. An agitator 817 is fixedly connected to the end of the connecting rod 813 away from the mounting frame 809. The servo motor 803 drives the screw 802 to rotate, causing the support frame 805 to move horizontally. This causes the connecting rod 813 and the agitator 817 to reciprocate along the adjustment groove 815, agitating the material in the feed frame 6, effectively preventing material blockage and ensuring smooth feeding. The agitator 817 has a pointed cone shape around its perimeter. Specifically, the agitator 817 is a hollow stainless steel block. The pointed cone design makes it easier for the agitator 817 to cut into and disperse materials. The hollow stainless steel structure reduces the weight of the stirring block 817, lowers the drive load, and is corrosion-resistant and durable, making it suitable for humid environments. A protective shell 804 is fixedly connected to one side of the fixing bracket 801 at the position corresponding to the servo motor 803.

A pull ring 812 is rotatably connected to the upper end of the mounting rod 810. The pull ring 812 is specifically a stainless steel ring. The pull ring 812 is designed to make it easy for the operator to manually pull the mounting rod 810, simplifying the disassembly and installation process.The stainless steel ring is wear-resistant and corrosion-resistant, improving durability and ease of operation. The lower end of the mounting rod 810 is arc-shaped, making it easier to align and insert the mounting rod 810 into the mounting hole 814 of the connecting rod 813, reducing jamming and wear, ensuring a firm connection and smooth operation. A roller 816 is rotatably connected to the arc surface of the connecting rod 813 at the position corresponding to the adjusting groove 815. The roller 816 slides against the inner wall of the adjusting groove 815, which is a corrugated groove. The roller 816 mates with the corrugated groove, reducing jamming and wear. The frictional resistance of the connecting rod 813 during movement makes the horizontal and vertical reciprocating motion smoother; the corrugated groove design converts the horizontal motion into vertical motion, enhances the mixing effect of the stirring block 817, and prevents material from clumping. A curtain sleeve 818 is fixedly connected to the upper surface of the feed frame 6. The end of the curtain sleeve 818 away from the feed frame 6 is fixedly connected to the feeding device 5. The curtain sleeve 818 can effectively seal the connection between the feed frame 6 and the feeding device 5, prevent material leakage and contamination, maintain a dry environment, and improve the hygiene and operating efficiency of the equipment. The working principle of the multi-layer flip-plate drying device provided by this utility model is as follows: By setting the adjustment structure 8, the servo motor 803 is first started. The output end of the servo motor 803 drives the screw 802 to rotate along the fixed frame 801. During this process, the screw 802 drives the support frame 805 to move horizontally along the inner wall of the fixed frame 801 and the round rod 806 via the thread. After the support frame 805 moves to one end of the fixed frame 801, the servo motor 803 is controlled to reverse, so that the support frame 805 moves horizontally and repeatedly within the fixed frame 801. During this process, the support frame 805 also drives the connecting rod 813 to move through the support plate 808 and the mounting frame 809, so that the connecting rod 813 moves along the… The adjusting groove 815 on the feed frame 6 slides, and the corrugated inner wall of the adjusting groove 815 exerts a vertical force on the connecting rod 813, causing the connecting rod 813 to reciprocate in the vertical direction. The connecting rod 813 drives the stirring block 817 to move, and the stirring block 817 agitates the material flowing through the feed frame 6 to prevent material blockage. When the connecting rod 813 moves in the vertical direction, the connecting rod 813 drives the support plate 808 to move up or down along the inner wall of the support frame 805 and the round rod 806 through the mounting frame 809. After the stirring block 817 needs to be replaced after a certain period of use, the mounting rod 810 moves upward and moves away from the connecting rod along the mounting frame 809. The mounting hole 814 on 813 releases the limiting position on the connecting rod 813, and the spring 811 is in a stretched state. Then, the connecting rod 813 is moved away from the mounting frame 809, so that the connecting rod 813 successively disengages from the mounting frame 809 and the adjusting groove 815 on the feed frame 6. Then, the connecting rod 813 and the stirring block 817 are taken out from the bottom of the feed frame 6. A new stirring block 817 and the connecting rod 813 are taken and put back into the mounting frame 809. The mounting rod 810 is released, and the mounting rod 810 is inserted downward into the mounting hole 814 under the action of the spring force of the spring 811, so that the position of the connecting rod 813 is fixed. The protective shell 804 can effectively protect the servo motor 803 from dust, moisture or external impact, and extend the motor's lifespan. The service life ensures stable operation of the adjustment structure 8; the pull ring 812 design facilitates manual pulling of the mounting rod 810 by the operator; the arc-shaped lower end makes it easier for the mounting rod 810 to be aligned and inserted into the mounting hole 814 of the connecting rod 813, reducing jamming and wear, ensuring a firm connection and smooth operation; the roller 816 cooperates with the corrugated groove to reduce the frictional resistance when the connecting rod 813 moves, making the horizontal and vertical reciprocating motion smoother; the corrugated groove design converts horizontal motion into vertical motion, enhancing the mixing effect of the stirring block 817 and preventing material agglomeration; the curtain sleeve 818 can effectively seal the connection between the feed frame 6 and the feeding device 5, preventing material leakage and contamination, maintaining a dry environment, and improving the hygiene and operating efficiency of the equipment.
