Description

Technical Field

[0001] This invention belongs to the field of hawthorn product processing technology, and specifically relates to a conveying device for processing hawthorn products. Background Technology

[0002] Hawthorn products, a traditional snack food loved by consumers, have seen their processing gradually become continuous and automated. As a core auxiliary device connecting various processing stages, the stability and cleanliness of the conveyor system directly affect production efficiency and food safety. With the expansion of production scale and the increase in production line speed, higher demands are placed on the conveyor system. It not only needs stable conveying capacity but also the ability to maintain the cleanliness of the conveyor surface during continuous operation, ensuring that the product is not secondary contaminated or has its appearance affected by residues.

[0003] Traditional conveyor belt cleaning methods mostly involve fixed scrapers or stationary brushes. The contact time between the cleaning components and the conveyor belt is short, and it's difficult to repeatedly clean stubborn, adherent areas. The removal effect on hardened deposits such as pectin and sugar formed after high-temperature or long-term transport is very limited. Secondly, the residues from hawthorn products are highly viscous and prone to clumping. Ordinary cleaning components (such as brushes) quickly become ineffective due to sugar coagulation, and the lack of an effective online self-cleaning mechanism leads to a rapid decline in cleaning efficiency. Frequent shutdowns for brush replacement or cleaning are often necessary, severely impacting production continuity. Therefore, those skilled in the art have provided a conveyor device for hawthorn product processing to solve the problems mentioned in the background. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and reasonably designed conveying device for processing hawthorn products in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A conveying device for processing hawthorn products includes a conveyor belt, a lead screw rotatably mounted on one side of the conveyor belt, a slide bar mounted on the other side of the conveyor belt, a drive assembly for driving the lead screw to rotate forward and backward on the power shaft of the conveyor belt, a receiving assembly for receiving dirt threaded on the side wall of the lead screw, and a cleaning assembly for cleaning the surface of the conveyor belt body in the middle of the receiving assembly. The front side of the inner wall of the conveyor belt support frame is provided with a disinfection mechanism for disinfecting the surface of the conveyor belt body, and the rear side of the inner wall of the conveyor belt support frame is provided with a cleaning plate for cleaning the cleaning components. During the conveyor belt process, impurities remain on the surface of the belt. On the return section of the conveyor belt, the surface of the conveyor belt is cleaned by the cleaning component. The conveyor belt can be driven by the drive component to rotate the slide bar in both directions, so that the receiving component can move synchronously along the screw and follow the belt body of the conveyor belt, extending the cleaning time of the cleaning component on the conveyor belt body. Finally, the receiving component and the disinfection mechanism work together to clean the surface of the conveyor belt body after cleaning. After the receiving component returns, the cleaning plate is used to clean the cleaning component.

[0006] Preferably, the drive assembly includes a mounting frame fixedly connected to the side wall of the fixed end of the conveyor belt, a drive gear fixedly connected to one end of the power shaft at the output end of the conveyor belt, a spline rod slidably passing through the inner wall of the mounting frame, a reversing gear intermittently meshing with the drive gear fixedly sleeved on the side wall of the spline rod, a first electric telescopic rod rotatably connected to one side of the bottom end of the mounting frame, a limit plate fixedly connected to the inner wall of the mounting frame, an adjusting plate fixedly sleeved on the side wall of the limit plate and the side wall of the limit plate, and the output end of the first electric telescopic rod rotatably connected to the bottom end of the adjusting plate.

[0007] Preferably, the receiving assembly includes a waste bin threaded onto the side wall of the lead screw, and the other side of the waste bin is slidably fitted onto the side wall of the slide bar. Air blowers are fixedly inserted through both sides of the receiving assembly, and an industrial camera is fixedly connected to the side wall of the waste bin.

[0008] Preferably, the cleaning component includes a mounting plate fixedly connected to the inner wall of the waste bin, a second electric telescopic rod fixedly connected to the top of the mounting plate, a reciprocating module fixedly connected to the output end of the second electric telescopic rod, a brush fixedly connected to the moving end of the reciprocating module, a roller pressing valve fixedly connected to the middle of the top of the brush, and air jet pipes fixedly connected to both sides of the roller pressing valve.

[0009] Preferably, the disinfection mechanism includes a fixed plate fixedly connected to the side wall of the conveyor belt fixing frame, a fixed pressing valve fixedly connected to the middle of the top of the fixed plate, a spray head fixedly connected to the top of the fixed pressing valve, and a liquid storage tank fixedly connected to the bottom of the fixed plate.

[0010] Preferably, a plurality of cleaning racks are fixedly provided at the front end of the cleaning plate.

[0011] Preferably, one end of the spline rod is in sliding engagement with one end of the lead screw.

[0012] Preferably, the conveyor belt body is integrally molded by blending food-grade PU and 10% PTFE powder, and the surface of the conveyor belt body is molded to form an array of round dot protrusions.

[0013] Preferably, the bristle length of the brush is much greater than the height of the roller pressing valve.

[0014] The beneficial effects of this invention are as follows: 1. In this invention, by employing a drive assembly to drive the lead screw in both forward and reverse directions, the receiving assembly can move synchronously with the conveyor belt along the return section of the conveyor belt. This significantly extends the contact time between the cleaning assembly and the belt, improving cleaning efficiency. The first electric telescopic rod in the drive assembly pushes the spline rod axially through the adjusting plate, causing the reversing gears to mesh alternately on both sides of the drive gear, thereby achieving the periodic forward and reverse rotation of the lead screw. During this process, the receiving assembly reciprocates along the lead screw and slide bar below the return section of the conveyor belt, allowing the brush to repeatedly clean the same area on the surface of the belt. This is especially effective in removing sticky sugars, pectin, and fruit pulp fragments remaining on hawthorn products. Compared to traditional fixed cleaning methods, this structure allows the cleaning assembly to dynamically follow and reciprocate without stopping the conveyor belt while it is running continuously, greatly improving cleaning coverage and the ability to remove stubborn stains.

[0015] 2. In this invention, the linkage between the brush, roller pressing valve, and air jet pipe automatically sprays air during the cleaning process to reduce the surface temperature of residues on the conveyor belt, thereby reducing the stickiness of the residues and ensuring long-term cleaning stability. When there is too much residue on the conveyor belt, the second electric telescopic rod pushes the brush up to contact the conveyor belt body, and the roller pressing valve opens synchronously under pressure. Gas stored in the external air source or compressed air pipeline is sprayed at high speed onto the surface of the conveyor belt body. This linkage mechanism realizes an adaptive cleaning mode of spraying air upon contact and stopping upon lifting, without the need for additional sensors or independent control systems. Especially when dealing with high-sugar, high-viscosity materials such as hawthorn products, the brush bristles are prone to clumping and failure due to sugar coagulation. At the same time, the high-pressure gas sprayed from the air jet pipe not only cools and blows the surface of the conveyor belt, but also assists in blowing and cleaning the brush bristles, effectively preventing the accumulation and hardening of sugar on the bristles. Through this synergistic effect of "cleaning-cooling-self-cleaning", the brush can maintain its sharp peeling ability in each cleaning cycle, overcoming the defect of traditional cleaning devices where the bristles are easily contaminated by sticky materials and quickly fail.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example: Figure 1 , Figure 2 As shown, a conveying device for hawthorn product processing includes a conveyor belt 1, a lead screw 7 rotatably mounted on one side of the conveyor belt 1, and a slide bar 8 mounted on the other side of the conveyor belt 1. A drive assembly 2 is mounted on the drive shaft of the conveyor belt 1 to drive the lead screw 7 in both forward and reverse directions. A receiving assembly 3 for catching dirt is threaded onto the side wall of the lead screw 7, and the other end of the receiving assembly 3 is slidably mounted on the slide bar 8. A cleaning assembly 4 for cleaning the surface of the conveyor belt 1 is mounted in the middle of the receiving assembly 3. A disinfection mechanism 5 for disinfecting the surface of the conveyor belt 1 is mounted on the front side of the inner wall of the support frame of the conveyor belt 1. A cleaning plate 6 for cleaning the cleaning assembly 4 is mounted on the rear side of the inner wall of the support frame of the conveyor belt 1. By employing a linkage structure of the conveyor belt 1, drive assembly 2, receiving assembly 3, cleaning assembly 4, disinfection mechanism 5, and cleaning plate 6, the conveyor belt 1 can automatically clean, disinfect, and self-clean its brushes during operation, preventing hawthorn product residue from contaminating subsequent products.

[0020] like Figure 1 - Figure 10 As shown, during the conveyor belt 1's transport of hawthorn products, impurities such as sugar, pectin, or fruit pulp fragments may remain on its surface. When conveyor belt 1 returns to its return stroke, cleaning component 4 cleans the surface of conveyor belt 1. Conveyor belt 1 is driven by drive component 2 to rotate screw 7 in both directions, allowing receiving component 3 to move synchronously along screw 7, thus extending the contact time between cleaning component 4 and conveyor belt 1 and improving cleaning efficiency. After cleaning, the surface of conveyor belt 1 is further disinfected when passing through disinfection mechanism 5. Simultaneously, when receiving component 3 returns, cleaning plate 6 automatically cleans cleaning component 4 to restore its cleaning ability.

[0021] It should be noted that the conveyor belt 1 is integrally molded by blending food-grade PU with 10% PTFE powder, and the surface of the conveyor belt 1 is molded with a dotted protrusion array. This design can effectively reduce the adhesion of sugar or pectin on the surface of hawthorn products to the conveyor belt. At the same time, the dotted protrusion array can reduce the contact area, further improve the cleaning effect, and avoid residues from contaminating subsequent products. The two work together to not only improve the smoothness of the conveying process, but also greatly facilitate the subsequent cleaning work and avoid cross-contamination of subsequent products by residues.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly 2 includes a mounting bracket 204 fixedly connected to the side wall of the fixed end of the conveyor belt 1. A drive gear 201 is fixedly connected to one end of the power shaft at the output end of the conveyor belt 1. The drive gear 201 is an end face gear. A spline rod 202 slides through the inner wall of the mounting bracket 204. A reversing gear 203 that intermittently meshes with the drive gear 201 is fixedly sleeved on the side wall of the spline rod 202. A first electric telescopic rod 205 is rotatably connected to one side of the bottom end of the mounting bracket 204. A limit plate 207 is fixedly connected to the inner wall of the mounting bracket 204. An adjusting plate 206 that is fixedly sleeved on the side wall of the limit plate 207 is slidably sleeved on the side wall of the limit plate 207. The output end of the first electric telescopic rod 205 is rotatably connected to the bottom end of the adjusting plate 206. One end of the spline rod 202 and one end of the lead screw 7 are slidably engaged through a spline sleeve or other means, which can transmit torque and allow axial relative movement. Thus, when the power shaft of the conveyor belt 1 rotates, the intermittent meshing of the drive gear 201 with different reversing gears 203 drives the lead screw 7 to rotate intermittently in both directions, thereby driving the receiving component 3 to reciprocate along the return section of the conveyor belt 1.

[0023] It should be noted that during actual operation, the extension and retraction of the first electric telescopic rod 205 causes the adjusting plate 206 to move laterally and reciprocally under the constraint of the limiting plate 207. This, in turn, causes the spline rod 202 and the two reversing gears 203 fixed thereon to move axially synchronously, changing their meshing position with the drive gear 201. When the first electric telescopic rod 205 extends, causing the first reversing gear 203 to mesh with the drive gear 201, the lead screw 7 rotates in the forward direction. When the first electric telescopic rod 205 retracts, causing the first reversing gear 203 to disengage from the drive gear 201, and simultaneously the second reversing gear 203 to mesh with the drive gear 201, the lead screw 7 rotates in the reverse direction. By precisely controlling the intermittent duration and frequency of the first electric telescopic rod 205 through the control center, the receiving component 3 can achieve controllable reciprocating motion below the return section of the conveyor belt 1. This design enables the cleaning component 4 to synchronously move and clean the surface of the conveyor belt 1, significantly improving the cleaning coverage and the ability to remove stubborn stains.

[0024] It should be noted that the axial travel of the spline rod 202 was determined based on multiple tests conducted by those skilled in the art. This ensures that before one reversing gear 203 completely disengages, the other reversing gear 203 has already entered the pre-engagement area. This guarantees that during the alternation process, only one reversing gear 203 maintains contact with the drive gear 201 to transmit torque. There is no "gap period" where both gears disengage simultaneously, and there will be no misalignment or jamming phenomena such as tooth tipping, jamming, or misalignment impact. This achieves a seamless alternation connection that is self-guaranteed by the mechanical structure. like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the receiving component 3 includes a waste bin 301 threadedly fitted onto the side wall of the lead screw 7. The waste bin 301 is used to collect hawthorn residue and dirt brushed off the surface of the conveyor belt 1 to prevent secondary pollution. A discharge port is provided at the bottom of the waste bin 301 to discharge the impurities collected in the waste bin 301, avoiding long-term accumulation that could cause odor to develop on the inner wall of the waste bin 301. The other side of the waste bin 301 is slidably fitted onto the side wall of the slide rod 8. Air blowers 302 are fixedly inserted through both sides of the receiving component 3, and the two air blowers 302 are inclinedly arranged on the inner wall of the waste bin 301. Furthermore, a fan is installed at the end of the air duct 302. This fan is existing technology, and its airflow strength has been determined through multiple tests by those skilled in the art to prevent excessive airflow from causing debris to scatter, and insufficient airflow from failing to achieve the desired effect. During operation, the fan draws in external air and blows it onto the surface of the conveyor belt 1. Its functions include: firstly, physically cooling the surface of the conveyor belt 1, thereby reducing the stickiness of hawthorn product residues (especially sugar); and secondly, creating an airflow barrier that helps blow the brushed debris deep into the waste bin 301, preventing it from scattering. This design provides favorable conditions for the subsequent efficient cleaning by the brush 401.

[0025] It is worth noting that an industrial camera 303 is fixedly connected to the side wall of the waste bin 301. The industrial camera 303 is used to acquire real-time cleaning images of the surface of the conveyor belt 1 and feed them back to the control center for image analysis. Based on the image analysis results, the control center can perform precise control. When it is detected that a certain area of ​​the conveyor belt surface is not clean enough, such as the area or thickness of residue exceeding the threshold, the control center can execute an optimization strategy, namely, increasing the reciprocating frequency of the reciprocating module 402 in that area or extending the dwell time, while controlling the extension of the second electric telescopic rod 404, so that the roller pressing valve 405 makes greater pressure contact with the belt surface, thereby causing the two jet pipes 406 to spray stronger high-pressure gas into the cleaning area to assist in cooling and descaling. This closed-loop feedback control based on machine vision significantly improves the intelligence level of the cleaning system and the consistency of the cleaning effect.

[0026] like Figure 1 , Figure 2 , Figure 5 - Figure 8As shown, the cleaning component 4 includes a mounting plate 403 fixedly connected to the inner wall of the waste bin 301. A second electric telescopic rod 404 is fixedly connected to the top of the mounting plate 403. A reciprocating module 402 is fixedly connected to the output end of the second electric telescopic rod 404. A limiting frame connected to the reciprocating module 402 is provided at the top of the mounting plate 403, which can improve the stability of the reciprocating module 402 during movement. A brush 401 is fixedly connected to the moving end of the reciprocating module 402. The reciprocating module 402 is existing technology, and its main structure includes a drive motor and a reciprocating screw. A slider is connected to the bottom end of the brush 401. The reciprocating movement of the brush 401 in a direction perpendicular to the movement of the conveyor belt 1 is realized by the cooperation of the slider and the reciprocating screw. A roller pressing valve 405 is fixedly connected to the middle of the top of the brush 401. The roller pressing valve 405 is existing technology. Air jet pipes 406 are fixedly connected to both sides of the roller pressing valve 405.

[0027] It should be noted that the roller of the roller pressing valve 405 is lower than the bristle plane of the brush 401. When the second electric telescopic rod 404 drives the brush 401 to rise and contact the conveyor belt 1, the roller pressing valve 405 contacts the surface of the conveyor belt 1 and is compressed, thereby opening the internal air passage and causing the jet pipe 406 to spray high-pressure gas to both sides of the brush 401. This process achieves multiple effects: First, the high-pressure gas can force cooling of the cleaning area, further reducing the stickiness of residues such as sugar; second, the continuous extension of the second electric telescopic rod 404 will increase the pressure of the brush 401 on the surface of the conveyor belt 1, thereby simultaneously... The system improves the mechanical scraping efficiency of the bristles against stubborn stains. Finally, the ejected airflow also assists in cleaning the bristles of brush 401 by blowing air, preventing a rapid decline in cleaning effectiveness due to excessive residue buildup. Furthermore, the bristle length of brush 401 is significantly greater than the height of the roller press valve 405. This dimensional difference ensures that when the roller press valve 405 is triggered by the surface of the conveyor belt 1, the bristles of brush 401 are already appropriately bent and closely adhered to the surface of the conveyor belt 1 for cleaning. This also prevents damage to the roller press valve 405 due to excessive bristle compression, ensuring the optimal balance between the reliability of the air circuit triggering and the cleaning effect. It should be further explained that, in most cases, only a small amount of impurities adhere to the surface of conveyor belt 1. In this case, it is sufficient to keep the receiving component 3 stationary at its initial position and rely on the rotation or reciprocating motion of the brush 401 to clean the surface of conveyor belt 1, thus achieving ideal cleaning efficiency. Only when unexpected situations occur on conveyor belt 1, such as a large area of ​​impurities or strong adhesion due to the overturning of a large number of hawthorn products, will the control center activate the reciprocating movement mode of the receiving component 3, making it move synchronously with the conveyor belt 1, thereby extending the cleaning time of the cleaning component 4 for specific dirty areas. This tiered cleaning strategy meets daily cleaning needs while avoiding unnecessary mechanical movement, reducing energy consumption and component wear.

[0028] like Figure 1 , Figure 2 , Figure 10 As shown, the disinfection mechanism 5 includes a fixed plate 501 fixedly connected to the side wall of the conveyor belt 1 fixing frame. A fixed press valve 502 is fixedly connected to the middle of the top of the fixed plate 501. The fixed press valve 502 is existing technology. The output end of the fixed press valve 502 is fixedly connected to a spray head 503 fixedly connected to the top of the fixed plate 501. A liquid storage tank 504 is fixedly connected to the bottom of the fixed plate 501. The liquid storage tank 504 contains food-grade disinfectant, such as peracetic acid or hydrogen peroxide disinfectant. It can be used on food contact surfaces, and no rinsing is required after disinfection. It can effectively disinfect food contact surfaces. The disinfection mechanism 5 is designed to resist yeast, mold, and bacteria. The specific working process is as follows: when the receiving component 3, carrying the cleaning component 4, moves along the screw 7 to the end of its stroke, i.e., close to the disinfection mechanism 5, the side wall of the waste bin 301 touches and squeezes the fixed pressure valve 502. This mechanical triggering action causes the disinfectant in the storage tank 504 to be pumped and atomized through the spray head 503, then evenly sprayed onto the surface of the freshly cleaned conveyor belt 1, achieving simultaneous disinfection and effectively killing any microorganisms that may grow, ensuring the food safety of the subsequently transported hawthorn products.

[0029] like Figure 1 , Figure 2 , Figure 9 As shown, the front end of the cleaning plate 6 is fixedly equipped with several cleaning racks 601. When the receiving component 3 completes a single cleaning cycle and begins its reverse return movement, the cleaning racks 601 on the cleaning plate 6 precisely insert into the bristles of the brush 401. As the receiving component 3 moves, the racks 601 forcibly peel off stubborn impurities such as hawthorn fibers and sugar clumps that are entangled or adhered to the bristles, thereby ensuring that the brush 401 returns to a clean state before the start of the next cleaning cycle. This self-cleaning design effectively maintains the long-term cleaning efficiency of the brush 401 and reduces the frequency of manual maintenance.

[0030] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
