[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The invention relates to a mesh belt conveyor device with a slide rail for a food quick-freezing machine. Through the setting of the conveying mechanism, when in use, the driving motor is matched with a gearbox, and the output speed and torque can be flexibly adjusted according to actual needs to ensure that it can fit various conveying scenarios. Through the coordinated operation of the transmission shaft, sprocket and chain, the stable transmission of power is guaranteed, so that the mesh belt can continuously and evenly convey objects, thereby improving production efficiency. The slide rail provides guidance and support for the slider and the conveying mechanism, effectively maintaining the stability of the chain movement path to avoid deviation or shaking. Multiple groups of sliders arranged at equal intervals evenly disperse the bearing pressure of the chain to prevent the chain from being damaged due to excessive local force. The chain is symmetrically distributed around the central axis of the mesh belt and matched with two groups of sprockets to ensure that the mesh belt is evenly stressed, eliminate the distortion and deviation of the mesh belt, and ensure the smooth conveying of objects. The mesh belt adopts a mesh structure, which can not only stably carry objects, but also allow cold air to fully pass through, and perfectly cooperates with the freezing function of the food quick-freezing machine, significantly improving the quick-freezing effect of food and ensuring product quality.
[0018] The present invention sets a tensioning adjustment mechanism. When in use, the threaded rod is driven by a servo motor, and the moving distance of the adjusting column is accurately controlled by the principle of thread transmission, thereby realizing precise adjustment of the chain tension. The chain tension can be flexibly adjusted according to different working conditions to ensure that the chain runs in the best state, avoid slipping due to excessive looseness, or wear and energy loss due to excessive tightness, and extend the service life of the chain. The cooperation between the limit groove and the limit block ensures the linear motion of the adjusting column and enhances the stability of the adjustment process. The first fixed plate and the second fixed plate provide reliable support and positioning for the threaded rod to ensure the stable rotation of the threaded rod. The multiple groups of rollers on the fixed column work together with the rollers on the adjusting column to assist in supporting and guiding the chain, reduce the friction between components, and make the chain move smoother. At the same time, when adjusting the tension, the chain and the slider are helped to better align with the eight-shaped head and stably enter the slide rail, thereby improving the reliability of the entire conveying system.
[0019] The present invention provides a cleaning mechanism. When in use, the cylinder drives the cylinder rod through the cylinder to drive the connecting plate to move up and down. Under the precise limiting and guidance of the limiting column, the cleaning action is ensured to be accurate and stable. The cleaning plate and the brush plate act successively to effectively remove ice and debris on the surface of the mesh belt, brush off residual materials and dust, keep the mesh belt clean, prevent pollutants from affecting the normal operation of the equipment and product quality, extend the service life of the equipment, and reduce maintenance costs. The fixed groove provides a reasonable movement space for the cleaning components, while limiting the movement range of the connecting plate to prevent excessive movement of the cleaning mechanism, thereby ensuring that the entire cleaning process is carried out within a safe and stable design range.

Detailed implementation manners
[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
[0031] Please refer to Figures 1-9, the present invention provides a technical solution: a belt conveyor device with a slide rail for a food quick-freezing machine, including a bottom plate 1, the upper surface of the bottom plate 1 is fixedly connected with side plates 2, the upper surface of the side plates 2 is fixedly connected with a food quick-freezing machine 3, one side surface of the side plates 2 is fixedly connected with a baffle 4, a conveying mechanism 5 is arranged on the inner surface of the side plates 2, the side plates 2 are connected with a tension adjusting mechanism 6, and a cleaning mechanism 7 is arranged on the upper surface of the side plates 2.
[0032] The conveying mechanism 5 includes a slide rail 501, an eight-shaped head 502, a slider 503, a chain 504, a mesh belt 505, a sprocket 506, a transmission shaft 507, a gearbox 508 and a driving motor 509. The inner surface of the side plate 2 is fixedly connected with the slide rail 501, and the two ends of the slide rail 501 are respectively fixedly connected with the eight-shaped head 502. The eight-shaped head 502 is a two arc-shaped plate structure, and the shape is close to the Chinese character "八". The inner surface of the slide rail 501 is slidably connected with the slider 503, and the one side surface of the slider 503 is fixedly connected with the chain 504, and the one side surface of the chain 504 is fixedly connected with the mesh belt 505. The outer surface of the chain 504 is meshed with the sprocket 506. A transmission shaft 507 is fixedly connected to the surface of one side, a gearbox 508 is fixedly connected to one end of the transmission shaft 507, and a drive motor 509 is fixedly connected to the surface of the gearbox 508 on one side. Through the arrangement of the slide rail 501, the eight-shaped head 502, the slider 503, the chain 504, the mesh belt 505, the sprocket 506, the transmission shaft 507, the gearbox 508 and the drive motor 509, when in use, the drive motor 509 is started, and the transmission shaft 507 is driven to rotate through the gearbox 508. The gearbox 508 can adjust the output speed and torque according to actual needs to meet different conveying requirements. The rotation of the transmission shaft 507 will drive the sprocket 506 to rotate, and the sprocket 506 can rotate. The rotation will drive the chain 504 meshing therewith to move. Since the chain 504 has a certain rigidity and strength, it can perform a circular motion under the drive of the sprocket 506. When the sprocket 506 rotates, it will drive the chain 504 to perform continuous motion through the chain links of the chain 504. The slider 503 slides on the inner surface of the slide rail 501. When the chain 504 moves, the slider 503 moves with the chain 504 and slides along the slide rail 501 at the same time. This can ensure that the chain 504 maintains a stable path during the movement, avoids its deviation or shaking during the movement, and ensures the quick freezing effect and product quality. At the same time, the mesh belt 505 is fixedly connected to the chain 5 04, with the movement of chain 504, mesh belt 505 will also move together. Mesh belt 505 can be used to carry items that need to be transported. Due to its mesh structure, it can not only ensure the carrying of items, but also allow cold air to pass through, thereby ensuring the freezing effect of food quick freezer 3. Slide rail 501 guides and supports slider 503 and the entire conveying mechanism 5. The eight-shaped head 502 is fixed at one end of the slide rail 501. After the slider 503 slides out of the slide rail 501, the slider 503 can be better returned to the slide rail 501, which plays a guiding role. The mesh belt 505 will not deviate, thereby increasing the uniformity of quick freezing, extending the service life, and reducing production costs.
[0033] Further, the side plates 2 are symmetrically arranged with respect to the central axis of the food quick-freezing machine 3, and the baffle plates 4 are symmetrically arranged with respect to the central axis of the food quick-freezing machine 3. By providing the baffle plates 4, during use, it can prevent the materials from overflowing from the side plates 2 during the conveying process. At the same time, the baffle plates 4 can, to a certain extent, assist the gas circulation inside the food quick-freezing machine 3 and prevent cold air from overflowing.
[0034] Further, multiple groups of sliders 503 are arranged at equal intervals on the surface of the chain 504. By providing the sliders 503, during use, arranging multiple groups of sliders 503 at equal intervals can evenly distribute the load-bearing capacity on the chain 504, prevent the chain 504 from deforming or being damaged due to excessive local stress, and ensure the smoothness and reliability of the conveying process.
[0035] Further, two chains 504 are symmetrically arranged with respect to the central axis of the mesh belt 505, two sets of slide rails 501 are correspondingly provided, and two sets of sprockets 506 are arranged on the outer surface of the transmission shaft 507. By providing the chains 504, during use, the chains 504 on both sides of the mesh belt 505 can simultaneously and evenly apply tension to the mesh belt 505, ensuring that the mesh belt 505 will not be distorted, deviated, etc. due to uneven stress during operation, and ensuring that the items can be smoothly conveyed on the mesh belt 505.
[0036] Furthermore, the tension adjustment mechanism 6 includes a limit groove 601, a limit block 602, an adjustment column 603, a threaded rod 604, a servo motor 605, a first fixing plate 606, a second fixing plate 607, a fixing column 608, a roller 609, and a sliding column 610. A limit groove 601 is provided on the inner surface of the side plate 2. The inner surface of the limit groove 601 is slidably connected to a limit block 602. One side surface of the limit block 602 is fixedly connected to an adjustment column 603. A threaded rod 604 is threadedly connected inside the adjustment column 603. One end of the threaded rod 604 is fixedly connected to a servo motor 605. One side surface of the side plate 2 is fixedly connected to a first fixing plate 606. One side surface of the side plate 2 is fixedly connected to a second fixing plate 607. The other side surface of the side plate 2 is fixedly connected to a fixing column 608. The outer surface of the fixing column 608 is fixedly connected to a roller 609. A sliding column 610 penetrates through the outer surface of the adjustment column 603. Through the settings of the limit groove 601, the limit block 602, the adjustment column 603, the threaded rod 604, the servo motor 605, the first fixing plate 606, the second fixing plate 607, the fixing column 608, the roller 609, and the sliding column 610, during use, the servo motor 605 is started to drive the threaded rod 604 to rotate. According to the principle of screw drive, when the threaded rod 604 rotates, the adjustment column 603 will move along the axial direction of the threaded rod 604. The limit block 602 will slide inside the limit groove 601 to prevent it from rotating during the movement, ensuring that the adjustment column 603 can only perform linear motion. The adjustment column 603 is connected to the chain 504 through the roller 609. When the adjustment column 603 moves downward, it will pull the chain 504 to make the chain 504 in a tensioned state. When the adjustment column 603 moves upward, it will loosen the chain 504, thereby realizing the tension adjustment of the chain 504. By precisely controlling the rotation angle of the servo motor 605, the moving distance of the adjustment column 603 can be precisely controlled, and then the precise adjustment of the tension of the chain 504 can be realized to meet the requirements of the tension of the chain 504 under different working conditions, ensure the normal operation of the chain 504, prevent the chain 504 from slipping due to being too loose, or increasing wear and energy loss due to being too tight. The first fixing plate 606 and the second fixing plate 607 play a role in supporting and positioning the threaded rod 604 to ensure that the threaded rod 604 can rotate stably. The roller 609 on the surface of the fixing column 608 will be connected to the chain 504, which can assist in supporting and guiding the chain 504. During the tension adjustment, the chain 504 and the slider 503 can be better aligned with the eight-head 502, and the chain 504 and the slider 503 can enter the slide rail 501 more stably. At the same time, the roller 609 can reduce the friction between components, making the chain 504 and the like move more smoothly during the movement.
[0037] Further, the inner dimension of the limit groove 601 matches the outer dimension of the limit block 602. The limit blocks 602 are symmetrically arranged with respect to the central axis of the adjustment column 603. Through the arrangement of the limit groove 601 and the limit block 602, during use, the limit block 602 slides inside the limit groove 601, and the limit groove 601 limits the limit block 602, making the movement of the adjustment column 603 more stable.
[0038] Further, both the first fixing plate 606 and the second fixing plate 607 are rotatably connected to the threaded rod 604. Two groups of fixing columns 608 are arranged on the surface of the side plate 2. Through the arrangement of the first fixing plate 606 and the second fixing plate 607, during use, they can play a role in supporting and positioning the threaded rod 604, ensuring that the threaded rod 604 can rotate stably and providing reliable support for the movement of the adjustment column 603.
[0039] Further, multiple groups of rollers 609 are arranged on the outer surface of the fixing column 608, and rollers 609 are also arranged on the outer surface of the adjustment column 603. Through the arrangement of the fixing column 608 and the rollers 609, during use, they can assist in supporting and guiding the chain 504. During tension adjustment, the chain 504 and the slider 503 can be better aligned with the eight-shaped head 502, and the chain 504 and the slider 503 can enter the slide rail 501 more stably. At the same time, the rollers 609 can reduce the friction between components, making the chain 504 and the like move more smoothly during the movement process.
[0040] Further, the cleaning mechanism 7 includes a flat plate 701, a support frame 702, a cylinder 703, a cylinder rod 704, a connecting plate 705, a limiting column 706, a fixing groove 707, a connecting block 708, a cleaning plate 709, a brush plate 710 and a hard brush 711. The upper surface of the side plate 2 is fixedly connected with the flat plate 701. The upper surface of the flat plate 701 is fixedly connected with the support frame 702. The upper surface of the support frame 702 is fixedly connected with the cylinder 703. The lower surface of the cylinder 703 is fixedly connected with the cylinder rod 704. The lower surface of the cylinder rod 704 is fixedly connected with the connecting plate 705. The upper surface of the connecting plate 705 is penetrated by the limiting column 706. The surface of the flat plate 701 is provided with the fixing groove 707. The lower surface of the connecting plate 705 is fixedly connected with the connecting block 708. One side surface of the connecting block 708 is fixedly connected with the cleaning plate 709. One side surface of the connecting block 708 is fixedly connected with the brush plate 710. The lower surface of the brush plate 710 is fixedly connected with the hard brush 711. Through the settings of the flat plate 701, the support frame 702, the cylinder 703, the cylinder rod 704, the connecting plate 705, the limiting column 706, the fixing groove 707, the connecting block 708, the cleaning plate 709, the brush plate 710 and the hard brush 711, when in use, starting the cylinder 703 can push the cylinder rod 704 to extend or retract. When the cylinder rod 704 expands and contracts, it will drive the connecting plate 705 to move up and down. The upper part of the connecting plate 705 is penetrated by the limiting column 706. The limiting column 706 plays a role in limiting and guiding, which can ensure that the connecting plate 705 keeps in the vertical direction during the up and down movement, avoiding tilting or deviation and ensuring the accuracy and stability of the cleaning action. The lower part of the connecting plate 705 is connected with the connecting block 708. The connecting block 708 is connected with the cleaning plate 709 and the brush plate 710. When the cylinder 703 pushes the cylinder rod 704 to extend, the cleaning plate 709 will contact the surface of the mesh belt 505 to shovel the ice or other sundries on its surface. The hard brush 711 under the brush plate 710 will clean the mesh belt 505 to brush off the residual materials, dust, etc. on the conveyor belt to keep the conveyor belt clean and prevent these pollutants from affecting the normal operation of the equipment and the product quality, so as to keep the mesh belt 505 clean and ensure the normal operation of the equipment and the product quality.
[0041] Further, there are two groups of support frames 702 symmetrically arranged with respect to the central axis of the flat plate 701. The limiting columns 706 are symmetrically arranged with respect to the central axis of the support frame 702. The inner size of the fixing groove 707 matches the outer sizes of the cleaning plate 709 and the brush plate 710. Through the setting of the fixing groove 707, when in use, the fixing groove 707 provides a certain space for the movement of the cleaning components, and at the same time can also limit the movement range of the connecting plate 705 to prevent it from moving excessively, ensuring that the entire cleaning mechanism 7 works safely and stably within the designed range.
[0042] Working principle: Start the drive motor 509, drive the drive shaft 507 to rotate through the gearbox 508. The gearbox 508 can adjust the output speed and torque according to actual requirements to meet different conveying requirements. The rotation of the drive shaft 507 will drive the sprocket 506 to rotate, and the rotation of the sprocket 506 will drive the engaged chain 504 to move. Since the chain 504 has a certain rigidity and strength, it can perform a cyclic motion under the drive of the sprocket 506. When the sprocket 506 rotates, it will drive the chain 504 to perform continuous motion through the chain links of the chain 504. The slider 503 slides on the inner surface of the slide rail 501. When the chain 504 moves, the slider 503 will move along with the chain 504 and slide along the slide rail 501 at the same time. This can ensure that the chain 504 maintains a stable path during the movement process, avoiding deviation or shaking during the movement process, ensuring the quick-freezing effect and product quality. At the same time, the mesh belt 505 is fixedly connected to one side surface of the chain 504. As the chain 504 moves, the mesh belt 505 will also move together. The mesh belt 505 can be used to carry the items to be conveyed. Due to its mesh structure, it can not only ensure the loading of the items, but also allow cold air to pass through, ensuring the freezing effect of the food quick-freezing machine 3. The slide rail 501 plays a guiding and supporting role for the slider 503 and the entire conveying mechanism 5. The eight-head 502 is fixed at one end of the slide rail 501. After the slider 503 slides out of the slide rail 501, it can make the slider 503 return to the slide rail 501 better, playing a guiding role, and the mesh belt 505 will not deviate, increasing the uniformity of quick-freezing and extending the service life, thereby reducing production costs. Then, the servo motor 605 can be started to drive the threaded rod 604 to rotate. According to the principle of screw drive, when the threaded rod 604 rotates, the adjusting column 603 will move along the axial direction of the threaded rod 604. The limit block 602 will slide on the inner side of the limit groove 601 to prevent it from rotating during the movement process, ensuring that the adjusting column 603 can only perform linear motion. The adjusting column 603 is connected to the chain 504 through the roller 609. When the adjusting column 603 moves downward, it will pull the chain 504 to make the chain 504 in a tensioned state. When the adjusting column 603 moves upward, it will relax the chain 504, thereby realizing the tension adjustment of the chain 504. By accurately controlling the rotation angle of the servo motor 605, the moving distance of the adjusting column 603 can be accurately controlled, and then the accurate adjustment of the tension of the chain 504 can be realized to meet the requirements of the tension of the chain 504 under different working conditions, ensuring the normal operation of the chain 504, preventing the chain 504 from slipping due to being too loose or increasing wear and energy loss due to being too tight. The first fixing plate 606 and the second fixing plate 607 play a role in supporting and positioning the threaded rod 604 to ensure that the threaded rod 604 can rotate stably. The roller 609 on the surface of the fixing column 608 will be connected to the chain 504, which can assist in supporting and guiding the chain 504. During the tension adjustment, it can make the chain 504 and the slider 503 better align with the eight-head 502.The chain 504 and the slider 503 can enter the slide rail 501 more stably. At the same time, the roller 609 can reduce the friction between components, making the chain 504 and the like move more smoothly during the movement.
[0043] When it is necessary to clean the mesh belt 505, the air cylinder 703 is started, which can push the air cylinder rod 704 to extend or retract. When the air cylinder rod 704 expands and contracts, it will drive the connecting plate 705 to move up and down. A limit post 706 penetrates through the upper part of the connecting plate 705. The limit post 706 plays a role in limiting and guiding, which can ensure that the connecting plate 705 remains vertical during the up and down movement, avoiding tilting or deviation, and ensuring the accuracy and stability of the cleaning action. The fixed groove 707 provides a certain space for the movement of the cleaning components, and at the same time, it can also limit the movement range of the connecting plate 705 to prevent it from moving excessively, ensuring that the entire cleaning mechanism 7 works safely and stably within the designed range. The lower part of the connecting plate 705 is connected to a connecting block 708, and the connecting block 708 is connected to a cleaning plate 709 and a brush plate 710. When the air cylinder 703 pushes the air cylinder rod 704 to extend, the cleaning plate 709 will contact the surface of the mesh belt 505, shoveling the ice or other sundries on its surface. The hard brush 711 under the brush plate 710 will clean the mesh belt 505, brushing off the residual materials, dust, etc. on the conveyor belt to keep the conveyor belt clean and prevent these pollutants from affecting the normal operation of the equipment and the product quality, so as to keep the mesh belt 505 clean and ensure the normal operation of the equipment and the product quality.
[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
