Description

Technical Field

[0001] This invention relates to the field of food industrial processing technology, specifically a belt conveyor for food industrial processing. Background Technology

[0002] In automated food processing production lines, belt conveyors are the core conveying equipment, widely used for the transfer and conveying of various food materials such as dough, pastries, and pre-made ingredients. Their conveying stability, adaptability, and smooth feeding directly affect the production efficiency and product quality of food processing. Existing belt conveyors for food processing still have many technical shortcomings in practical applications: 1. Traditional conveyors mostly have a fixed conveying distance, which cannot be flexibly adjusted according to the different needs of food processing procedures, material specifications and production line layout. The equipment has poor adaptability and is difficult to adapt to the conveying and processing needs of multiple working conditions and multiple types of food. It lacks versatility. On the other hand, existing belt conveyors with adjustable conveying distance lack adaptive support mechanisms as the conveying distance increases. As a result, when the conveying distance increases, the middle of the conveyor belt is prone to collapse and sagging due to the weight of the food materials themselves, causing problems such as uneven material conveying. 2. The tensioning structure of conventional conveyor belts is mostly manually adjustable. During long-term conveying operations, the conveyor belt is prone to loosening due to stretching and wear. This can lead to problems such as conveyor belt slippage, conveying deviation, and running jams, affecting the continuity and stability of material conveying. It also requires staff to frequently stop the machine to adjust the tension, which greatly reduces the efficiency of continuous production in the food industry. Manual adjustment is inaccurate, time-consuming, and labor-intensive. 3. Sticky food materials such as dough and soft, glutinous pastries tend to stick to the conveyor belt surface during transportation. Existing conveyors lack targeted auxiliary feeding structures and rely solely on the material's own weight for feeding. This results in incomplete feeding and a large amount of residue, causing material to enter the return end of the conveyor belt. This not only wastes food materials but also interferes with subsequent conveying operations, significantly reducing the overall processing efficiency of the production line and failing to meet the high-precision, high-efficiency, and high-hygiene production standards required by modern food industry. Summary of the Invention

[0003] The purpose of this invention is to provide a belt conveyor for industrial food processing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a belt conveyor for industrial food processing, comprising a mounting frame, a support frame fixed to the side of the mounting frame, a motor fixed on the mounting frame, the output shaft of the motor fixed to a drive roller, a bearing connected to the mounting frame, the drive roller connected to a conveyor belt, and the conveyor belt connected to a tension control mechanism. The tension control mechanism utilizes gravity to adjust the tension of the conveyor belt. An adjustment mechanism is fixed on the support frame, which is used to adjust the conveying distance and provide support for the conveyor belt. An auxiliary feeding mechanism is installed on the adjustment mechanism to assist in feeding materials onto the conveyor belt.

[0005] Preferably, the tension control mechanism includes guide rollers connected to the mounting frame by bearings with equal spacing, and the guide rollers are connected to the conveyor belt. The normal operation of the conveyor belt can be ensured through the guiding effect of the guide rollers.

[0006] Preferably, the tension control mechanism further includes a first guide rail fixed on the mounting frame, and the first guide rail and the first slider are slidably connected. The first slider is symmetrically fixed on the counterweight plate, and the front and rear counterweight plates are connected to the movable rollers by bearings. The movable rollers are connected to the conveyor belt. Through the sliding action between the first guide rail and the first slider, the distance between the movable roller and the guide roller can be adjusted, thereby providing a basic guarantee for the control of the conveyor belt conveying distance. Furthermore, through the gravity of the counterweight plate and the first guide rail, the tension of the conveyor belt can be achieved by gravity, ensuring the normal operation of the device.

[0007] Preferably, the adjustment mechanism includes a cylinder fixed on the mounting frame, and a movable platform is fixed to the output end of the cylinder. A second slider is symmetrically fixed to the rear side of the movable platform, and the second slider is slidably connected to the second guide rail. The second guide rail is symmetrically fixed to the support frame. By extending and retracting the cylinder, the movable platform can be driven to move, thereby providing a basic guarantee for the control of the conveyor belt conveying distance. Furthermore, the sliding guidance between the second slider and the second guide rail can ensure the stability of the movable platform's movement.

[0008] Preferably, the movable platform is connected to a driven roller with a rough surface, and the driven roller is connected to the conveyor belt. The upper surface of the driven roller is flush with the upper surface of the driving roller. The movable platform drives the driven roller to move, thereby adjusting the distance between the driving roller and the driven roller, and thus realizing the adjustment of the conveyor belt length.

[0009] Preferably, a support is also fixed on the movable platform, and one end of the support is rotatably connected to the scissor-type telescopic frame. The other end of the scissor-type telescopic frame is rotatably connected to the horizontal plate, while the horizontal plate is fixed on the mounting frame. The movable platform drives the support to move, thereby driving one end of the scissor-type telescopic frame to move, thus providing a basic force for the retraction or expansion of the scissor-type telescopic frame and ensuring the normal operation of the device.

[0010] Preferably, the rotatable position on the central axis of the bracket is connected to the support frame via a rotating shaft, and the support frame is connected to a bearing with a roller. The roller contacts the conveyor belt to provide support, and the upper end face of the roller is flush with the upper end face of the driven roller. A T-shaped slider is also fixed to the rear end face of the support frame, and the T-shaped slider is slidably connected to the mounting frame and the support frame. By extending and retracting the scissor-type telescopic frame, the support frame can be moved, thereby achieving equal spacing adjustment between several support frames, and further achieving spacing adjustment between several rollers. This ensures the support effect of the rollers on the conveyor belt, avoids problems such as collapse and dent of the conveyor belt due to the weight of the material, and ensures the normal operation of the device. When the support frame moves, the sliding guide effect between the T-shaped slider and the mounting frame and the support frame can ensure the stability of the support frame movement.

[0011] Preferably, the auxiliary feeding mechanism includes a swing arm rotatably connected to the support frame, and a torsion spring connecting the swing arm and the support frame. A swing roller is connected to a bearing on both the front and rear swing arms, with the upper surface of the swing roller flush with the upper surface of the driven roller. The maximum swing angle of the swing roller is 45°. Through the rotational action between the swing arm and the support frame, the inclination angle of the conveyor belt between the swing roller and the driven roller can be adjusted, thereby increasing the peeling angle between the material and the conveyor belt, thus better separating the material from the conveyor belt. Furthermore, the elastic action of the torsion spring provides a basic force for the automatic reset of the swing arm and the swing roller, ensuring the normal operation of the device.

[0012] Preferably, the swing arm is also fixed with a protrusion, and the protrusion and the lever are slidably connected. The lever is symmetrically fixed on the rotation shaft of the driven roller. The driven roller drives the lever to rotate. With the contact sliding action between the lever and the protrusion, a basic force can be provided for the swing arm to swing, thereby ensuring the normal operation of the device.

[0013] Preferably, the lever and the side plate are slidably connected, and the side plate is symmetrically fixed to the base plate. A sliding rod is also symmetrically fixed to the base plate, and the sliding rod is slidably connected to the bracket. A spring is also fixed between the base plate and the bracket. The sliding rod is fixed to the fixed plate, and a top roller is connected to the fixed plate by a bearing. The top roller contacts the conveyor belt, and its upper surface is flush with the upper surface of the driven roller. Through the sliding action between the lever and the side plate, a basic force can be provided for the movement of the side plate, thereby providing a basic force for the movement of the base plate, sliding rod, fixed plate, and top roller. Combined with the elasticity of the spring, this provides a basic guarantee for the active reset of the base plate, sliding rod, fixed plate, and top roller. This allows the top roller to reciprocate against the conveyor belt, generating vibration and further reducing the adhesion between the material and the conveyor belt.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This belt conveyor for industrial food processing is equipped with a dedicated adjustment mechanism. Stable sliding is achieved by a cylinder-driven movable platform that works in conjunction with a second slider and a second guide rail. The conveying distance between the active and driven rollers can be flexibly adjusted to precisely adapt to the conveying needs of different food processing steps, material specifications, and production line layouts. This solves the problems of fixed conveying distances and poor adaptability of traditional conveyors. Furthermore, during the conveying distance adjustment process, adaptive compensation can be achieved through the length of the conveyor belt between the guide roller and the movable roller. No manual disassembly or modification of the equipment is required, making adjustment convenient and efficient. This significantly improves the equipment's versatility and applicability, adapting to the diverse production needs of the industrial food sector. 2. This belt conveyor for industrial food processing utilizes a gravity-based tension control mechanism. Relying on the weight of the counterweight plate, it continuously applies tension to the conveyor belt. Combined with the sliding guidance of the first slider and the first guide rail, it can achieve stable adaptive displacement of the movable roller. During the long-term operation of the conveyor belt, including stretching and conveying distance adjustment, it can automatically compensate for the slack of the conveyor belt in real time, always keeping the conveyor belt in a constant tension state. This completely eliminates faults such as conveyor belt slippage, deviation, and jamming, eliminating the need for frequent manual shutdowns for debugging. It effectively ensures the continuity and stability of food conveying operations, significantly reduces equipment maintenance costs and labor intensity, and improves the continuous operation efficiency of the production line. 3. This belt conveyor for industrial food processing, through the cooperative structure of scissor-type telescopic frame, bracket, and T-shaped slider, can synchronously achieve equal spacing adaptive adjustment of multiple sets of idlers as the conveying distance is adjusted. Under any conveying length condition, the idlers can uniformly support the conveyor belt conveying area, effectively counteracting the downward pressure force caused by the gravity of the food materials, avoiding the collapse and sagging of the middle of the conveyor belt, ensuring the flatness of the conveyor belt surface, preventing material deviation, accumulation, deformation, etc. during the conveying process, effectively ensuring the quality of conveyed food materials, and reducing the product defect rate; 4. This belt conveyor for industrial food processing employs an auxiliary feeding mechanism. On one hand, the driven roller rotates, driving the lever to periodically squeeze the side plate. Combined with the elastic restoring effect of the spring, this drives the top roller to perform orderly up-and-down reciprocating motion, causing slight vibrations at the feeding end of the conveyor belt. This effectively breaks the adhesion between sticky materials and the conveyor belt surface, weakening the material's bonding effect. On the other hand, the sliding lever squeezes the protrusion, driving the swing arm to deflect and causing the swing roller to swing downward, forming a material peeling angle. This creates an inclined angle at the feeding end of the conveyor belt, utilizing the normal separation force of the material's own weight to further reduce the adhesion area between the material and the conveyor belt. This dual action works synergistically to completely solve the problems of residue, adhesion, and jamming of sticky materials such as dough and soft, glutinous ingredients during feeding, significantly improving feeding thoroughness and reducing material waste.

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

[0018] Please see Figures 1-6 This invention provides a technical solution: a belt conveyor for industrial food processing, including a mounting frame 1, a support frame 2 fixed to the side of the mounting frame 1, a motor 3 fixed on the mounting frame 1, the output shaft of the motor 3 fixed to a drive roller 4, the drive roller 4 bearing connected to the mounting frame 1, the drive roller 4 connected to a conveyor belt 5, the conveyor belt 5 connected to a tension control mechanism 6, the tension control mechanism 6 using gravity to adjust the tension of the conveyor belt 5, an adjustment mechanism 7 fixed on the support frame 2, the adjustment mechanism 7 used to adjust the conveying distance and provide support for the conveyor belt 5, and an auxiliary feeding mechanism 8 installed on the adjustment mechanism 7, the auxiliary feeding mechanism 8 used to assist in the feeding of materials on the conveyor belt 5.

[0019] The tension control mechanism 6 includes guide rollers 601 connected to the mounting frame 1 by bearings at equal intervals, and the guide rollers 601 are interconnected with the conveyor belt 5; the tension control mechanism 6 also includes a first guide rail 602 fixed to the mounting frame 1, and the first guide rail 602 and the first slider 603 are slidably connected, and the first slider 603 is symmetrically fixed on the counterweight plates 604, while the front and rear counterweight plates 604 are connected to movable rollers 605 by bearings, and the movable rollers 605 are interconnected with the conveyor belt 5; the adjustment mechanism 7 includes a fixed A cylinder 701 is mounted on the mounting frame 1, and a movable platform 702 is fixed to the output end of the cylinder 701. A second slider 703 is symmetrically fixed to the rear side of the movable platform 702. The second slider 703 is slidably connected to the second guide rail 704, which is symmetrically fixed to the support frame 2. A driven roller 705 with a rough surface is connected to the movable platform 702 by a bearing. The driven roller 705 is connected to the conveyor belt 5, and the upper end face of the driven roller 705 is flush with the upper end face of the driving roller 4. When using this belt conveyor for industrial food processing, such as Figures 1-6As shown, firstly, the length of the conveyor belt 5 for material conveying is adjusted according to actual usage requirements. By controlling the extension and retraction of the cylinder 701, the movable table 702 can be moved. Combined with the sliding guidance between the second slider 703 and the second guide rail 704, the stability of the movable table 702's movement is ensured. The movement of the movable table 702 synchronously drives the driven roller 705 and the top roller 810 to move, thereby adjusting the distance between the driven roller 705 and the driving roller 4. When the driven roller 705 and the top roller 810 move, they generate a traction force on the conveyor belt 5. This causes the conveyor belt 5 to act on the movable roller 605, causing the movable roller 605 and the counterweight plate 604 to move relative to the guide roller 601, in conjunction with the second slider 703 and the second guide rail 704. The sliding action between the slider 603 and the first guide rail 602 ensures the stability of the movement of the counterweight plate 604 and the movable roller 605, thereby adjusting the length of the conveyor belt 5 between the guide roller 601 and the movable roller 605. By using the length of the conveyor belt 5 between the guide roller 601 and the movable roller 605 to compensate for the length of the conveyor belt 5 between the driven roller 705 and the driving roller 4, the conveyor belt 5 can be used to adjust the length of material conveying, so as to better meet the actual use requirements. During the process of adjusting the length of material conveying, the automatic gravity of the counterweight plate 604 and the movable roller 605 always exerts a force on the conveyor belt 5, thereby ensuring the tension of the conveyor belt 5 and preventing the conveyor belt 5 from becoming loose and affecting the normal operation of the device. A bracket 706 is fixed on the movable platform 702, and one end of the bracket 706 is rotatably connected to the scissor-type telescopic frame 707. The other end of the scissor-type telescopic frame 707 is rotatably connected to the horizontal plate 708, and the horizontal plate 708 is fixed on the mounting frame 1. The rotatable position on the central axis of the bracket 706 is connected to the bracket 709 through a rotating shaft. The bracket 709 is connected to the roller 710 by a bearing, and the roller 710 contacts the conveyor belt 5 to provide support. The upper end face of the roller 710 is flush with the upper end face of the driven roller 705. A T-shaped slider 711 is fixed on the rear end face of the bracket 709, and the T-shaped slider 711 is slidably connected to the mounting frame 1 and the support frame 2. When adjusting the length of conveyor belt 5 for conveying materials, such as Figures 1-6As shown, the movement of the movable platform 702 can synchronously drive the support 706 to move, thereby driving one end of the scissor-type telescopic frame 707 to move, thus realizing the contraction or extension of the scissor-type telescopic frame 707. When the scissor-type telescopic frame 707 contracts or extends, it can synchronously drive the bracket 709 to move. With the sliding guide effect between the T-shaped slider 711 and the mounting frame 1 and the support frame 2, the stability of the movement of the bracket 709 can be ensured, thereby realizing the equal spacing adjustment between several brackets 709, and thus realizing the equal spacing adjustment between several idlers 710. By supporting the material conveying length of the conveyor belt 5 with several idlers 710, the flatness of the material conveying length of the conveyor belt 5 can be ensured, avoiding problems such as the collapse of the conveyor belt 5 due to the gravity of the material, ensuring the normal operation of material conveying, and better meeting the actual use needs. The auxiliary feeding mechanism 8 includes a swing arm 801 rotatably connected to the support frame 2, with a torsion spring connecting the swing arm 801 to the support frame 2. Two swing arms 801 are connected to a swing roller 802 via bearings, with the upper surface of the swing roller 802 flush with the upper surface of the driven roller 705. The maximum swing angle of the swing roller 802 is 45°. A protrusion 803 is also fixed to the swing arm 801, and the protrusion 803 is slidably connected to a lever 804. The lever 804 is symmetrically fixed to the rotation shaft of the driven roller 705. 804 and side plate 805 are slidably connected, and side plate 805 is symmetrically fixed on base plate 806. Slide rod 807 is also symmetrically fixed on base plate 806. Slide rod 807 is slidably connected to bracket 706. Spring 808 is fixed between base plate 806 and bracket 706. Slide rod 807 is fixed to fixed plate 809. Top roller 810 is connected to fixed plate 809 by bearing. Top roller 810 is in contact with conveyor belt 5. The upper end face of top roller 810 is flush with the upper end face of driven roller 705. After adjusting the length of conveyor belt 5 for material conveying, as follows: Figures 1-6 As shown, the motor 3 drives the active roller 4 to rotate clockwise, which can drive the conveyor belt 5 to operate. With the frictional force between the conveyor belt 5 and the driven roller 705 and the swing roller 802, the driven roller 705 and the swing roller 802 can rotate clockwise synchronously. During the process of conveying sticky materials (such as dough) on the conveyor belt 5, the material moves from left to right on the conveyor belt 5 to achieve the conveying function. When the driven roller 705 rotates, it synchronously drives the lever 804 to rotate. When the lever 804 contacts and slides with the side plate 805, the side plate 805 is forced to move the bottom plate 806, slide bar 807, fixed plate 809 and top roller 810 upward a certain distance. At this time, the spring 808 is compressed. When the lever 804 separates from the side plate 805, the bottom plate 806, slide bar 807, fixed plate 809 and top roller 810 can automatically reset under the elastic action of the spring 808. According to the above principle, when the material moves to the top roller 810, the driven roller 705 drives the lever 804 to rotate. With the contact and sliding action between the lever 804 and the side plate 805 and the elastic action of the spring 808, the top roller 810 can move up and down in an orderly manner, thereby causing the conveyor belt 5 on the left side of the driven roller 705 to vibrate up and down, thereby effectively breaking the adhesion between the sticky material and the conveyor belt 5, so as to facilitate better subsequent material feeding. When the driven roller 705 drives the lever 804 to rotate, and the lever 804 slides in contact with the protrusion 803, the swing arm 801 can be deflected downwards by force, thereby driving the swing roller 802 to swing downwards. As a result, there is an angle (i.e., the peeling angle of the material) between the conveyor belt 5 between the swing roller 802 and the driven roller 705 and between the driven roller 705 and the driving roller 4. When the material moves from the conveyor belt 5 between the driven roller 705 and the driving roller 4 to the conveyor belt 5 between the swing roller 802 and the driven roller 705, the material layer is subjected to bending strain due to the peeling angle, causing the bonding interface between the material and the conveyor belt 5 to have a peeling tendency. Furthermore, since the conveyor belt 5 between the swing roller 802 and the driven roller 705 is inclined downwards, the component of the material's own weight along the normal direction of the conveyor belt 5 points in the separation direction, further weakening the effective bonding area between the material and the conveyor belt 5, and better separating the material from the conveyor belt 5, thus avoiding the adhesion of sticky materials to the conveyor belt 5 and affecting the normal feeding function.
