Description

Technical Field

[0001] This invention relates to the field of conveyor technology, and specifically to a feeding conveyor for a wet almond peeling machine. Background Technology

[0002] In existing almond wet peeling production lines, food-grade belt or chain conveyors are commonly used for material transfer during the feeding and conveying process. The main body of the equipment uses a 304 stainless steel frame, paired with a food-grade conveyor belt or perforated chain plate, to meet the hygiene and corrosion resistance requirements of wet processing. The conveyor typically consists of a drive unit, driving and driven rollers, a conveying surface, and a frame. Some models are equipped with a feed hopper and guide baffles to stabilize the material flow and ensure uniform feeding. This type of conveying device has a mature structure and reliable operation, and is widely used in nut wet processing scenarios, meeting the basic requirements for automated feeding.

[0003] In existing technologies, the conveyor lacks angle and height adjustment capabilities; its conveying angle and height are completely fixed. This means it can only serve a specific peeling machine at a specific height and location. In actual installation sites, even slight differences in ground level or slight deviations in the peeling machine's feed inlet from the original design can prevent the conveyor from being installed and used properly, resulting in poor equipment versatility. Furthermore, in existing technologies, almonds, especially after long-term storage or preliminary screening, often have a large amount of dust on their surface during transport. Without a dust collection device, this dust will be blown into the air during conveyor belt vibration and material tumbling, permeating the entire workshop. Additionally, existing technologies lack tension adjustment components. When the conveyor belt inevitably stretches after a period of use, the slack belt will severely slip on the drive rollers, causing the conveyor belt to stop or operate weakly. Material accumulates at the feed end and cannot be conveyed, essentially losing its feeding function. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a feeding conveyor for a wet almond peeling machine, which solves the problems in related technologies where the conveyor does not have angle and height adjustment functions, and its conveying angle and height are completely fixed, resulting in it only serving a specific peeling machine at a specific height and position; during the conveying process, especially after long-term storage or preliminary screening, the surface of almonds often has a large amount of dust, affecting the working environment; and when the conveyor belt inevitably stretches after a period of use, the loose conveyor belt will severely slip on the drive roller.

[0005] At least one embodiment of the present invention provides a feeding conveyor for a wet almond peeling machine, comprising: A cross-shaped base, the bottom of which is fixedly connected to four casters, all of which are self-locking casters; An angle adjustment assembly is disposed on top of the cross base and is used to adjust the pitch angle and horizontal rotation of the conveyor.

A connecting block is rotatably connected to the top of each of the two connecting rods, and a connecting rod is rotatably connected to the top of each of the two connecting blocks. The tops of the two connecting rods are close to each other and rotatably connected to a fixed frame. The two connecting rods and the two connecting rods form a parallelogram structure.

[0009] According to one embodiment of this application, a motor three is fixedly connected to the front side wall of the front connecting block, the output shaft of the motor three passes through the rear side wall of the front connecting block and is fixedly connected to a lead screw, the rear connecting block is threaded to the outer wall of the lead screw through an internal threaded hole, and a limit block is fixedly connected to the rear end of the lead screw.

[0010] According to one embodiment of this application, the top of the base plate is fixedly connected to two left-right symmetrical limiting telescopic rods, and the tops of the two limiting telescopic rods are fixedly connected to the bottom of the fixed frame.

[0011] According to one embodiment of this application, a conveyor cleaning assembly includes a conveyor frame, which is a rectangular frame structure. The conveyor frame is fixedly connected to a fixed frame. Conveyor rollers are rotatably connected to both the left and right sides inside the conveyor frame. A conveyor motor is fixedly connected to the left side inside the conveyor frame. The output shaft of the conveyor motor passes through the rear side wall of the conveyor frame and is fixedly connected to a toothed pulley. The rear end of the left conveyor roller passes through the rear side wall of the conveyor frame and is fixedly connected to a toothed pulley. A synchronous toothed belt is sleeved on the outer wall of the toothed pulley and the toothed pulley and the toothed pulley rotate through the sleeved synchronous toothed belt.

[0012] According to one embodiment of this application, the inner top wall of the conveyor frame is fixedly connected to two symmetrical and downwardly extending supports. The bottom of each of the two supports is rotatably connected to a transmission roller. A conveyor belt is sleeved on the outside of the two transmission rollers and the two transmission rollers. The surface of the conveyor belt is provided with micro-through holes, and a number of convex strips distributed at equal intervals on the left and right are fixedly connected to the surface of the conveyor belt.

[0013] According to one embodiment of this application, two conveyor rollers separate the conveyor belt and the top of the conveyor frame into a dust collection space. An open dust collection box located in the dust collection space is fixedly connected to the top of the conveyor frame. Several dust collection pipes are fixedly connected to the rear side of the open dust collection box. A vacuum cleaner is fixedly connected to the top of the cross base. A dust collection duct is fixedly connected to the air inlet of the vacuum cleaner. The end of the dust collection duct away from the vacuum cleaner is fixedly connected to several dust collection pipes. A dust collection box is fixedly connected to the top left side of the cross base. The air outlet of the vacuum cleaner communicates with the inside of the dust collection box through a duct.

[0014] According to one embodiment of this application, the conveyor belt tension adjustment assembly includes two fixed plates, which are respectively fixedly connected to the left side of the front and rear sides of the conveyor frame.

[0015] This invention provides a feeding conveyor for a wet almond peeling machine. Compared with existing technologies, by incorporating angle and height adjustment components, operators can flexibly adjust the conveyor's pitch angle according to actual site conditions. This ensures the conveyor's discharge end precisely aligns with the peeling machine's inlet, preventing material spillage or accumulation due to height mismatch. This flexibility allows one device to adapt to various peeling machines of different specifications, greatly improving the equipment's versatility and applicability. Furthermore, the conveyor's discharge end can be precisely adjusted to the required height, ensuring the material falls accurately and smoothly into the peeling machine, achieving seamless connection between devices. The included conveyor cleaning component further enhances the cleaning capabilities during material transport. Simultaneously, continuous negative pressure suction is applied to the surface of the conveyor belt and its surrounding environment. This design allows dust adhering to the surface of the raw materials and impurities such as outer skin debris that falls off due to friction during transportation to be sucked away and collected immediately, improving the workshop production environment and realizing integrated transportation and cleaning operations. This avoids the need for additional cleaning procedures before materials enter the next process. Through the set conveyor belt tension adjustment component, operators can adjust the height of the tension roller at any time, thereby increasing the positive pressure between the conveyor belt and the drive roller and restoring sufficient friction. This can effectively prevent slippage and idling caused by the conveyor belt being too loose, ensuring that the power output of the motor can be stably transmitted to the conveyor belt, and ensuring continuous and reliable feeding operations.

The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] like Figures 1-2 As shown, it illustrates a feeding conveyor for a wet almond peeling machine according to an embodiment of the present invention, comprising: The cross base 1 has four casters 10 fixedly connected to its bottom, and all four casters 10 are self-locking casters. Angle adjustment component 2 is located on top of cross base 1 and is used to adjust the pitch angle and rotate the conveyor horizontally. Height adjustment component 3 is located on top of angle adjustment component 2 and is used to adjust the height of the conveyor. Conveyor cleaning component 4 is located on top of height adjustment component 3 and is used to perform dust extraction when conveying almond raw materials. The conveyor belt tension adjustment component 5 is located on the left side of the conveyor cleaning component 4 and is used to adjust the tension of the conveyor belt.

[0026] In some examples, the cross base 1 serves as the mounting base for the entire device. It is welded from high-strength stainless steel and has a stable structure. Four casters 10 are fixedly connected to the four ends of the bottom of the cross base 1. For example, the Greesky 4-inch heavy-duty casters are used. These casters have a built-in brake and self-locking function, which facilitates positioning and fixing of the device after it is moved.

[0027] like Figure 3 As shown, an angle adjustment component 2 is illustrated in another embodiment of the present invention. The angle adjustment component 2 includes two side plates 20, which are fixedly connected to the front and rear sides of the top of the cross base 1. A rotating shaft 21 is rotatably connected to the opposite surfaces of the front and rear side plates 20. A rotating ring 22 is rotatably connected to the side of the front and rear side plates 20 that is far apart from each other. A rotating frame 23 is fixedly connected to the outer wall of the two rotating rings 22. A motor 24 fixedly connected to the top of the cross base 1 is provided in front of the front side plate 20, and a motor 25 fixedly connected to the top of the cross base 1 is provided behind the rear side plate 20.

[0028] The output shaft of motor 1 24 passes through the front rotating ring 22 and the front side plate 20 and extends to the rear side wall of the front side plate 20, and is fixedly connected to the rotating shaft 21. The output shaft of motor 25 is fixedly connected to the rear rotating ring 22. A bevel gear 1 26 is fixedly connected to the outer wall of the rotating shaft 21. A bevel gear 27 is meshed with the top of bevel gear 1 26. A rotating column 28 is fixedly connected to the top of bevel gear 27. The top of the rotating column 28 passes through to the top of the rotating frame 23 and its outer wall is rotatably connected to the rotating frame 23.

[0029] In some examples, two side plates 20 are vertically fixed to the front and rear sides of the top of the cross base 1. The opposite surfaces of the front and rear side plates 20 are rotatably connected to a rotating shaft 21 via bearings. The sides of the front and rear side plates 20 that are far apart from each other are rotatably connected to a rotating ring 22 via bearings. The outer walls of the two rotating rings 22 are fixedly connected to an inverted "U"-shaped rotating frame 23. Motor 1 24 and Motor 2 25 can be speed-regulating motors with reducers, such as YSJ series gear reducers.

[0030] Furthermore, the output shaft of motor 24 passes through the front rotating ring 22 and the front side plate 20 via a key connection, and extends to the rear side wall of the front side plate 20. It is fixedly connected to the front end of the rotating shaft 21 via a coupling. The output shaft of motor 25 is fixedly connected to the rear rotating ring 22 via a key connection. A bevel gear 26 is fixedly connected to the outer wall of the rotating shaft 21 via a key. A bevel gear 27 is meshed with the top of bevel gear 26. A rotating column 28 is fixedly connected to the top of bevel gear 27. The top of the rotating column 28 extends to the top of the rotating frame 23. Furthermore, its outer wall is rotatably connected to the through hole at the top of the rotating frame 23 via a bearing. When the first motor 24 drives the rotating shaft 21 to rotate, the first bevel gear 26 drives the second bevel gear 27 and the rotating column 28 to rotate. At the same time, the second motor 25 drives the rotating ring 22 to rotate, causing the entire rotating frame 23 and the components above it to rotate around the axis of the rotating shaft 21. Through the coordinated action of the first motor 24 and the second motor 25, the combined motion of the rotating column 28 rotating itself and the rotating frame 23 swinging as a whole can be achieved, thereby precisely adjusting the pitch angle and horizontal rotation of the upper conveyor.

[0031] like Figure 4 As shown, a height adjustment component 3 is illustrated in another embodiment of the present invention. The height adjustment component 3 includes a base plate 30, which is fixedly connected to the top of the rotating column 28. Two front-to-back symmetrical connecting rods 31 are rotatably connected to the top center of the top of the base plate 30. A connecting block 32 is rotatably connected to the top of each of the two front-to-back connecting rods 31. A connecting rod 33 is rotatably connected to the top of each of the two front-to-back connecting blocks 32. The tops of the two connecting rods 33 are close to each other and rotatably connected to a fixing frame 36. The two connecting rods 31 and the two connecting rods 33 form a parallelogram structure.

[0032] A motor 34 is fixedly connected to the front side wall of the front connecting block 32. The output shaft of the motor 34 passes through the rear side wall of the front connecting block 32 and is fixedly connected to a lead screw 35. The rear connecting block 32 is threadedly connected to the outer wall of the lead screw 35 through an internal threaded hole. A limit block is fixedly connected to the rear end of the lead screw 35.

[0033] Two left-right symmetrical limiting telescopic rods 37 are fixedly connected to the top of the base plate 30, and the top of the two limiting telescopic rods 37 are fixedly connected to the bottom of the fixed frame 36.

[0034] In some examples, the base plate 30 is fixedly connected to the top of the rotating column 28. The top center of the base plate 30 is rotatably connected to two symmetrical connecting rods 31. The tops of the two connecting rods 31 are rotatably connected to connecting blocks 32 via pins. The tops of the two connecting blocks 32 are rotatably connected to connecting rods 33 via pins. The tops of the two connecting rods 33 are close to each other and are rotatably connected to a fixed frame 36 via pins. The two connecting rods 31, the two connecting rods 33, the base plate 30, and the connecting blocks 32 together constitute a telescopic parallelogram lifting mechanism, ensuring the stability of the lifting process.

[0035] To achieve automated lifting, a motor 34 is fixedly connected to the front wall of the front connecting block 32. The motor 34 can be a 57BYG250B stepper motor, used with a driver to achieve precise displacement control. The output shaft of the motor 34 passes through the rear wall of the front connecting block 32 via a coupling and is fixedly connected to a lead screw 35. The rear connecting block 32 is threaded to the outer wall of the lead screw 35 through a precision threaded hole. A limit block is fixedly connected to the rear end of the lead screw 35 to prevent the connecting block from coming off. When the motor 34 drives the lead screw 35 to rotate, since the front connecting block 32 is fixed, the rear connecting block 32 will move back and forth along the lead screw 35, thereby changing the included angle between the two connecting rods 1 31 and 2 33, realizing the lifting and lowering of the fixed frame 36. To increase stability, two symmetrical left and right limiting telescopic rods 37 are fixedly connected to the top of the base plate 30. The tops of the two limiting telescopic rods 37 are fixedly connected to the bottom of the fixed frame 36 to guide and limit the lifting and lowering of the fixed frame 36.

[0036] like Figures 5-7 As shown, a conveyor cleaning assembly 4 according to another embodiment of the present invention is illustrated. The conveyor cleaning assembly 4 includes a conveyor frame 40, which is a rectangular frame structure. The conveyor frame 40 is fixedly connected to a fixed frame 36. Conveyor rollers 41 are rotatably connected to both the left and right sides inside the conveyor frame 40. A conveyor motor 411 is fixedly connected to the left side inside the conveyor frame 40.

A dust collection box 410 is fixedly connected to the top left side of the cross base 1. The air outlet of the vacuum cleaner 48 is connected to the inside of the dust collection box 410 through a duct.

[0039] In some examples, the conveyor frame 40 is a rectangular frame structure welded from stainless steel square tubing. The conveyor frame 40 is fixedly connected to the fixed frame 36. Conveyor rollers 41 are rotatably connected to the left and right sides of the conveyor frame 40 via bearings. A conveyor motor 411 is fixedly connected to the left side of the conveyor frame 40. The conveyor motor 411 can be an S9 series geared motor with a power of 1.1kW and waterproof and dustproof functions. The output shaft of the conveyor motor 411 extends through the rear wall of the conveyor frame 40 and is fixedly connected to a toothed pulley 412. The rear end of the left conveyor roller 41 extends through the rear wall of the conveyor frame 40 and is fixedly connected to a toothed pulley 414. The outer walls of the toothed pulleys 412 and 414 are fitted with… There is a synchronous toothed belt 413. The conveyor motor 411 drives the left conveyor roller 41 to rotate through the synchronous belt transmission mechanism composed of toothed pulley 412, synchronous toothed belt 413 and toothed pulley 414. Two symmetrical and downward extending brackets 44 are fixedly connected to the inner top wall of the conveyor frame 40. The bottom of the two brackets 44 is rotatably connected to the driven roller of the transmission roller 45 through the bearing. The two conveyor rollers 41 and the two transmission rollers 45 are covered with a conveyor belt 42. The surface of the conveyor belt 42 has a large number of micro-holes to facilitate dust collection. Several equidistant convex strips 43 are fixedly connected to the surface of the conveyor belt 42 by heat fusion or bonding to prevent almonds from slipping and rolling on the conveyor belt and to ensure conveying efficiency.

[0040] Furthermore, two conveyor rollers 45 separate a dust collection space between the conveyor belt 42 and the top of the conveyor frame 40. An open dust collection box 46 located in this dust collection space is fixedly connected to the top of the conveyor frame 40. The opening of the open dust collection box 46 faces the conveyor belt 42. Several dust collection pipes 47 are fixedly connected to the rear side of the open dust collection box 46 through pipe joints. A vacuum cleaner 48 is fixedly connected to the top of the cross base 1. The vacuum cleaner 48 can be a Nitto industrial vacuum cleaner, model AT-360, which has a strong negative pressure suction. The air inlet of the vacuum cleaner 48 is fixedly connected to a dust collection duct 49 through a clamp. The end of the dust collection duct 49 away from the vacuum cleaner 48 is fixedly connected to and communicates with several dust collection pipes 47 through a multi-port connector. A dust collection box 410 is fixedly connected to the top left side of the cross base 1. The air outlet of the vacuum cleaner 48 communicates with the inside of the dust collection box 410 through a duct. Almond skin fragments and other debris are sucked into the dust collection box 410 for centralized processing.

[0041] like Figures 7-8 As shown, this invention illustrates a conveyor belt tension adjustment assembly 5 in another embodiment. The conveyor belt tension adjustment assembly 5 includes two fixed plates 50, which are respectively fixedly connected to the left side of the front and rear sides of the conveyor frame 40. Each of the two fixed plates 50 has a vertically arranged slide groove 51 inside, and a slider 52 is limited and slidably mounted inside each of the two slide grooves 51. A tension roller 55 is rotatably connected to the opposite face of the two sliders 52. The upper outer wall of the tension roller 55 rolls and fits against the lower outer wall of the conveyor belt 42. The bottom of each of the two fixed plates 50 is threadedly connected to a screw 53 through a threaded hole. The top of the screw 53 extends into the interior of the slide groove 51 and is rotatably connected to the slider 52. A knob 54 is fixedly connected to the bottom of the screw 53.

[0042] In some examples, two fixed plates 50 are vertically fixed to the lower left sides of the front and rear sides of the conveyor frame 40, respectively. Each fixed plate 50 has a vertically arranged groove 51 inside. A slider 52 is slidably installed inside each groove 51, with a clearance fit between the slider 52 and the groove 51. A tension roller 55 is rotatably connected to the opposing surfaces of the two sliders 52 via bearings. The upper outer wall of the tension roller 55 rolls against the lower outer wall of the conveyor belt 42. A screw 53 is threadedly connected to the bottom of each fixed plate 50 through threaded holes. 53 is a T-shaped thread with self-locking properties. The top of the screw 53 extends into the interior of the slide groove 51 and is rotatably connected to the bottom of the slider 52 through a thrust bearing. This allows the slider 52 to move up and down without rotating when the screw 53 rotates. A manual knob 54 is fixedly connected to the bottom of the screw 53 for easy operation. By rotating the knob 54, the operator can drive the screw 53 to rotate, thereby causing the slider 52 to slide up and down in the slide groove 51. This adjusts the height of the tension roller 55, achieving precise adjustment of the tension of the conveyor belt 42 and preventing the conveyor belt from running off-track or slipping.

[0043] The working principle and usage process of this invention: The operator first pushes the cross base 1 and uses the four casters 10 installed at its bottom to move the entire equipment to the feed port of the wet peeling machine. After reaching the designated position, the operator steps on the brake pedal of the casters 10 to lock the equipment firmly and prevent displacement during operation.

[0044] When the pitch angle of the conveyor needs to be adjusted, motors 24 and 25 in the angle adjustment assembly 2 are activated. Motor 24 drives the rotating shaft 21, which is fixedly connected to its output shaft, to rotate. The bevel gear 26 on the rotating shaft 21 rotates accordingly, and drives the bevel gear 27, which meshes with it, to rotate. This causes the rotating column 28, which is fixed to the bevel gear 27, to rotate under the support of the top bearing of the rotating frame 23. At the same time, motor 25 drives the rotating ring 22, which is fixedly connected to its output shaft, to rotate. Since the rotating ring 22 is fixedly connected to the rotating frame 23, the rotation of the rotating ring 22 will drive the entire rotating frame 23 and all components installed above the rotating frame 23, including the height adjustment assembly 3 and the conveyor cleaning assembly 4, to pitch and swing around the rotating shaft 21. Through the combined motion of motors 24 and 25, the overall pitch angle of the conveyor can be swung, and it can also be rotated horizontally to finely adjust the orientation of the upper components, thereby accurately aligning the discharge end of the conveyor frame 40 with the feed inlet of the peeling machine.

[0045] After initial angle adjustment, the motor 34 in the height adjustment assembly 3 is activated. The motor 34 drives the lead screw 35, which is fixedly connected to its output shaft, to rotate. Since the front connecting block 32 is fixed to the housing of the motor 34, and the rear connecting block 32 engages with the lead screw 35 through a threaded hole, the rotation of the lead screw 35 drives the rear connecting block 32 to move along the axial direction of the lead screw 35. The movement of the rear connecting block 32 changes the included angle between the two connecting rods 1 31 and 2 33. When the rear connecting block 32 moves forward and approaches the front connecting block 32, the included angle between the connecting rods 1 31 and 2 33 increases. The lifting mechanism, composed of a parallelogram structure, raises the fixed frame 36 and the conveyor frame 40 above it; conversely, it lowers it. During this process, the two limiting telescopic rods 37 extend and retract with the lifting of the fixed frame 36, ensuring the vertical stability of the lifting process and preventing the conveyor frame 40 from swaying. In this embodiment, by setting the angle adjustment component 2 and the height adjustment component 3, the operator can flexibly adjust the pitch angle of the conveyor according to the actual situation on site, so that the discharge end of the conveyor can accurately connect with the feed inlet of the peeling machine, avoiding material spillage or accumulation due to height mismatch. This flexibility allows one device to be adapted to a variety of peeling machines of different specifications, greatly improving the versatility and applicability of the equipment. At the same time, through simple operation (such as motor-driven lead screw), the discharge end of the conveyor can be precisely adjusted to the required height, ensuring that the material can fall accurately and smoothly into the peeling machine, realizing seamless connection between devices.

[0046] Then, the conveyor motor 411 is started, and its output shaft drives the toothed pulley 412 to rotate. The toothed pulley 412 transmits torque to the toothed pulley 414 through the synchronous toothed belt 413, thereby driving the left conveyor roller 41 (drive roller) which is coaxially and fixedly connected to the toothed pulley 414 to rotate. The rotation of the drive roller drives the conveyor belt 42 to circulate on the right conveyor roller 41 (driven roller) and the two transfer rollers 45 through friction. The almond raw material to be processed is placed at the feed end of the conveyor belt 42. As the conveyor belt 42 moves, the raw material moves steadily towards the discharge end under the obstruction and pushing of multiple protrusions 43 fixedly connected to the surface of the conveyor belt 42, and finally falls into the feed hopper of the peeling machine. The design of the protrusions 43 effectively prevents the almonds from rolling and sliding during inclined conveying.

[0047] While the conveyor belt 42 is running, the vacuum cleaner 48 is activated. The vacuum cleaner 48 generates a strong negative pressure at its air inlet. This negative pressure is transmitted through the suction duct 49 and multiple suction pipes 47 to the open suction box 46 fixed at the top inside the conveyor frame 40. Since the opening of the open suction box 46 faces the inner surface of the conveyor belt 42, and the two transmission rollers 45 separate the conveyor belt 42 and the top inside the conveyor frame 40 into a relatively closed suction space, when the conveyor belt 42 passes through this area, the suction generated at the opening of the open suction box 46 will draw the debris, dust, etc. that are attached to the surface of the almonds or fall off the almonds and onto the conveyor belt 42 during the conveying process into the open suction box 46 through the micro-holes opened on the surface of the conveyor belt 42. Then, through the suction pipes 47, the suction duct 49, and the vacuum cleaner 48, it is finally discharged into the dust collection box 410 for centralized collection. This process realizes the integration of conveying and cleaning, and avoids the flying almond peels polluting the environment. In this embodiment, the conveyor cleaning component 4 can continuously perform negative pressure suction on the surface of the conveyor belt and the surrounding environment while the material is being conveyed. This design allows dust adhering to the surface of the raw materials and impurities such as outer skin debris that fall off due to friction during the conveying process to be sucked away and collected in the first instance, improving the workshop production environment and realizing the integrated operation of conveying and cleaning, thus avoiding the need to arrange additional cleaning steps before the material enters the next process.

[0048] During long-term use, the conveyor belt 42 may become loose, leading to slippage or deviation. In this case, the operator can manually rotate the knob 54 in the conveyor belt tension adjustment component 5. The knob 54 drives the screw 53 to rotate in the threaded hole of the fixed plate 50. Since the top of the screw 53 is rotatably connected to the slider 52 and does not produce axial displacement, the rotation of the screw 53 will drive the slider 52 to slide vertically in the groove 51. When the knob 54 is rotated clockwise, the slider 52 moves upward, driving the tension roller 55 rotatably connected to it to move, thereby increasing the pressure of the tension roller 55 on the lower surface of the conveyor belt 42 and making the conveyor belt 42 tensile. Conversely, when the knob 54 is rotated counterclockwise, the tension decreases. In this way, the tension of the conveyor belt 42 can be easily adjusted to ensure the smooth operation of the conveyor belt 42. In this embodiment, the conveyor belt tension adjustment component 5 allows the operator to adjust the height of the tension roller at any time, thereby increasing the positive pressure between the conveyor belt and the drive roller and restoring sufficient friction. This can effectively prevent slippage and idling caused by the conveyor belt being too loose, ensuring that the power output of the motor can be stably transmitted to the conveyor belt and guaranteeing the continuous and reliable feeding operation.
