Description

Technical Field

[0001] This invention relates to the field of biscuit feeding and packaging technology, and more specifically, to a food quantitative feeding device. Background Technology

[0002] After the dough is prepared, rolled, baked, and cooled, the biscuits are conveyed to a packaging machine for quantitative packaging, which can be divided into large, medium, and small packages according to demand. Currently, quantitative packaging equipment on the market uses multiple biscuit conveyor lines to feed the biscuits in parallel, stacking them sequentially on the conveyor entering the packaging equipment, so that the biscuits are stacked into large, medium, and small finished packages.

[0003] The aforementioned packaging effectively achieves quantitative biscuit packaging; however, due to the need for multiple conveyor lines installed in parallel, it is difficult to adapt to some small factories. Existing biscuit quantitative dispensing equipment occupies a large dedicated space during installation, making it difficult to meet the installation needs of factories of varying sizes. Therefore, there is an urgent need for an improved food quantitative dispensing device based on existing equipment, which significantly reduces the dedicated installation space required and can accommodate installations in a wider range of factories of different sizes. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a food quantitative feeding device, which completes the quantitative feeding of biscuits through a set of conveying components and a receiving plate that can move up and down, thereby reducing the installation space occupied and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a food quantitative feeding device, comprising a frame and packaging equipment, wherein the packaging equipment is located at the end of the frame, only one set of conveying components is mounted on the top of the frame, a second conveyor chain is mounted on the frame, and a weighting component is mounted at the bottom of the conveying components; The end of the conveyor is bent vertically, and its opening is provided with multiple tubular structures that bend along the conveyor belt. The tubular structures are connected by horizontal pipe fittings to form a protective cover. The component includes a U-shaped base. The base and the conveyor are adjustable vertically. Two receiving plates and two unloading plates are set on one side of the base. The receiving plates are located directly below the conveyor and are set horizontally. The end of the receiving plate is rotatably connected to the unloading plate. The unloading plate is set at an angle. Two side plates are installed on the frame, and two conveyor chains are respectively installed on the sides of the two side plates; Two sets of conveyor chains are set between the two conveyor chains. A lever is installed between the two conveyor chains via a connecting shaft. Torsion springs are installed at both ends of the connecting shaft. Under normal conditions, the lever is perpendicular to the conveyor chain.

[0006] In a preferred embodiment, the lever passes through the recessed position of the base, and two feed plates are located on both sides of the movement path of the lever.

[0007] In a preferred embodiment, a stopper is provided on the frame, and the connecting shaft can contact the stopper; The blocking component is a metal plate with a rubber strip at its bottom. Both ends of the connecting shaft extend through the chain plate of the first conveyor chain and contact the rubber strip.

[0008] In a preferred embodiment, torsion springs at both ends of the connecting shaft reset the lever when the connecting shaft disengages from the blocking member.

[0009] In a preferred embodiment, the installation height of conveyor chain one is lower than that of conveyor chain two, and the end of conveyor chain one is inclined downward through a set of gears.

[0010] In a preferred embodiment, a torsion spring structure is provided on the connecting shaft between the feeding plate and the receiving plate, and a limiting structure is provided at the end of the receiving plate to restrict the rotation range of the feeding plate.

[0011] In a preferred embodiment, a fixing member is installed in the adjustment hole, the base is fixed to the side of the conveyor by the fixing member, and the distance between the receiving plate and the bottom of the conveyor is adjustable.

[0012] In a preferred embodiment, the two ends of the first conveyor chain are driven by a gear structure, and the gear structure at the end of the first conveyor chain causes the end of the first conveyor chain to tilt.

[0013] The technical effects and advantages of this invention are as follows: 1. The quantitative feeding of biscuits can be completed by installing only one set of conveyor components, which abandons the traditional solution that requires multiple conveyor components to be installed in parallel to control the quantitative feeding of biscuits. This greatly reduces the installation space and meets the installation needs of various small and medium-sized processing plants. 2. By moving the base of the component up and down, the distance between the receiving plate and the bottom of the conveyor can be adjusted, thereby precisely controlling the number of cookies stacked on the receiving plate. The farther the receiving plate is from the bottom of the conveyor, the more cookies can be stacked. The operation is simple and the adjustment is convenient. 3. The first conveyor chain drives the lever to rotate. The lever enters from the retraction position of the component and pushes the biscuit from the horizontal section of the receiving plate to the unloading plate. Following the movement of the lever, the biscuit is conveyed to the second conveyor chain. At the same time, a stopper is set on the frame. The friction between the connecting shaft and the stopper causes the lever to rotate in the opposite direction of the conveying. This prevents the lever from affecting the verticality of the stacked biscuits when it retracts, ensuring that the biscuits are stacked neatly and that the quantitative feeding is accurate and reliable.

[0022] 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.

[0023] After the dough is prepared, rolled, baked, and cooled, the biscuits are conveyed to the packaging machine for quantitative packaging. They can be divided into large, medium, and small packaging quantities according to demand. Currently, quantitative packaging equipment on the market uses multiple biscuit conveyor lines to feed the biscuits in parallel, stacking them one by one on the conveyor entering the packaging equipment, so that the biscuits are stacked into large, medium, and small finished product packages.

[0024] Currently, the aforementioned packaging can effectively handle the quantitative dispensing and packaging of biscuits. However, because it requires multiple conveyor lines to be installed in parallel, it is difficult to adapt to some small factories. Therefore, improvements have been made to the existing biscuit quantitative dispensing equipment to significantly reduce its installation space, making it suitable for installation in factories of varying sizes.

[0025] As attached Figure 1 With appendix Figure 7The food quantitative feeding device shown includes a frame 1 and a packaging device 7 located at the end of the frame 1. In a conventional packaging line, multiple conveyor components 6 are arranged side by side along the length of the top of the frame 1. In the design solution of this application, only one set of conveyor components 6 is arranged.

[0026] A second conveyor chain 5 is set on the frame 1, and a weighting component 4 is set at the bottom of the conveyor 6 to quantitatively convey the number of biscuits. The biscuits fall into the second conveyor chain 5 after passing through the weighting component 4, and are then put into the packaging equipment to complete the packaging.

[0027] The end of the conveyor 6 is bent vertically and faces the frame 1. The entire conveyor 6 is installed on the frame 1 through a bracket (not shown in the figure). The conveyor 6 specifically includes a conveyor belt, which can be bent vertically by rollers. Adaptive side plate structures are set on both sides of the conveyor belt to ensure that the biscuits can be stably conveyed on the conveyor belt. The conveyor 6 is prior art and is not an improvement of the technical solution of this application. Unlike the prior art, at the opening of the conveyor, the traditional closed cover is replaced with multiple tubular structures that bend along the conveyor belt. The multiple tubular structures are then connected by multiple horizontally placed pipes to form an enclosure 601, forming a protective cover installed on the conveyor to prevent the biscuits from falling. Compared with the traditional completely enclosed protective equipment, the conveying of the biscuits can be directly observed and adjustments can be made in time.

[0028] The component 4 specifically includes a U-shaped base. Two receiving plates 404 and two unloading plates 405 are provided on one side of the base. The base is installed on the side plate of the conveyor 6 via a fixing member 403. The receiving plates 404 are integrally set with the base and are horizontally positioned directly below the conveyor 6. The ends of the receiving plates 404 are rotatably connected to the unloading plates 405 via a shaft. A limiting structure is provided at the ends of the receiving plates 404. The unloading plates 405 are inclined. A torsion spring structure is provided on the connecting shaft between the unloading plates 405 and the receiving plates 404 to ensure that the unloading plates 405 can rotate around the receiving plates 404 within a certain range and form an angle of 155-165 degrees with the plane of the frame 1. There is a gap between the two receiving plates 404 and the unloading plates 405, and the gap is smaller than the diameter of the biscuit.

[0029] An adjustment hole 401 is provided on the base. A fixing component 403, such as a bolt, can be installed in the adjustment hole 401 to fix the base to the side of the conveyor 6. By adjusting the installation of the base, the distance between the receiving plate 404 and the bottom of the conveyor 6 is controlled, thereby controlling the number of cookies stacked on the receiving plate 404. The farther the receiving plate 404 is from the bottom of the conveyor 6, the more cookies can be stacked. A clearance position 402 is also provided on the base. The width of the clearance position 402 is the same as the distance between the unloading plate 404 and the unloading plate 404.

[0030] Two side plates 2 are set on the frame 1, with a gap between the two side plates 2. Two conveyor chains 2 5 are respectively set on the sides of the two side plates 2. The gap between the two conveyor chains 2 5 is smaller than the diameter or width of the biscuit. When the biscuit falls into the conveyor chain 2 5 through the feeding plate 405, it is fed into the packaging equipment for packaging.

[0031] To ensure that the biscuits can slowly fall from the feed plate 405 into the second conveyor chain 5, a first conveyor chain 3 is set between the two second conveyor chains 5. The first conveyor chain 3 is a chain plate structure and two sets are set. A lever 301 is installed between the two first conveyor chains 3 via a connecting shaft 303. The two ends of the connecting shaft 303 pass through the chain plates of the first conveyor chain 3, and torsion springs (not shown in the figure) are set at both ends of the connecting shaft 303. The lever 301 can rotate on the chain plate, and a limiting structure (not shown in the figure) is set on the chain plate. Under normal conditions, the lever 301 is in a vertical state with the first conveyor chain 3.

[0032] The conveyor chain 3 is driven to rotate at both ends by gear structures, and an additional gear structure is added at the end of the conveyor chain 3 to ensure that the end of the conveyor chain 3 is inclined. When the conveyor chain 3 is moving, the biscuit slides down from the feed plate 405 through the lever 301 structure. During operation, the lever 301 rotates to the bottom of the component 4, enters from the base clearance position 402 of the component 4, pushes the biscuit from the horizontal section of the receiving plate 404 to the feed plate 405, and follows the movement of the lever 301 to the conveyor chain 5 for conveying. The lever 301 passes between the two feed plates 404 during its movement.

[0033] An extension plate 101 is provided at the end of the frame 1 for mounting the gear structure of the conveyor chain 3.

[0034] The rotation speed of conveyor chain 25 is faster than that of conveyor chain 113, ensuring that if the biscuits are stacked when passing through the inclined section of the feed plate 405, they will lean against the lever 301. As the biscuits continue to be pushed forward when conveying to conveyor chain 25, the lever 301 will swing the biscuits to ensure that the biscuits are stacked neatly. During installation, the height of conveyor chain 13 is lower than that of conveyor chain 25 to ensure that the biscuits can contact the conveying surface of conveyor chain 25 after falling from the feed plate 405.

[0035] To prevent the lever 301 from interfering with the biscuit packaging process, a set of gears tilts the end of conveyor chain 3 downwards, ensuring that the lever 301 can naturally move downwards and exit the conveying surface of conveyor chain 5 when it rotates to the end. Furthermore, to ensure that the downward movement of the lever 301 does not affect the neatness of the stacked biscuits, the lever 301 must rotate backwards, i.e., in the opposite direction to the biscuit conveying direction, as it moves downwards.

[0036] refer to Figure 5 and Figure 6 To this end, a stopper 302 is installed on the frame 1 via a connecting rod. The organizing member 301 is a metal plate with a rubber strip at the bottom. The connecting shaft 303 for mounting the lever 301 extends through the chain plate at both ends and contacts the rubber strip structure at the bottom of the stopper 302. When the conveyor chain 3 moves, the friction between the connecting shaft 303 and the organizing member 302 causes the lever 301 to rotate in the opposite direction of the conveying direction, thereby preventing the lever 301 from affecting the verticality of the biscuit stack. When the conveyor chain 3 continues to move, when the connecting shaft 303 retracts from contact with the organizing member 302, the connecting shaft 303 automatically resets via a torsion spring structure.

[0037] Compared to existing products, this product can quantitatively feed biscuits using only one set of conveyor components 6, eliminating the need for multiple conveyor components 6 installed side-by-side to control the quantitative feeding. This significantly reduces installation space and meets the installation needs of various small and medium-sized processing plants. In operation, the number of biscuits is controlled by adjusting the distance between the receiving plate 404 and the conveyor component 6 by moving the base of the conveyor component 4 up and down. Initially, the biscuits are conveyed under the conveyor component 6. This can be achieved manually by placing the biscuits on the receiving plate 404, or through other automated equipment; this part is not considered an improvement in this application.

[0038] As a technical solution to replace manual labor, a counting sensor (not shown in the figure) is installed above the starting end of the conveyor 6. This counting sensor is electrically connected to the drive motor of the conveyor 6. When the counting sensor detects that the number of cookies passing through the conveyor 6 has reached a preset threshold, it sends a pause signal to the drive motor, causing the conveyor 6 to stop conveying. At this time, the cookies that have been conveyed to the receiving plate 404 fall onto the surface of the receiving plate 404 by gravity and are stacked. After a preset delay, the drive motor restarts and continues to convey cookies to the receiving plate 404. The counting sensor can be a photoelectric sensor or a laser sensor.

[0039] Alternatively, a rotatable baffle (not shown in the figure) can be installed at the end of the conveyor 6, which is electrically connected to the controller. When cookies need to be stacked, the controller controls the baffle to rotate to the outlet at the end of the conveyor 6, temporarily blocking the cookies from falling, so that the subsequently conveyed cookies are stacked sequentially above the receiving plate 404. After the number of stacked cookies reaches the set value, the controller controls the baffle to rotate away from the outlet, and the stacked cookies fall to the horizontal section of the receiving plate 404. The baffle can be driven by an electromagnet or a small cylinder.

[0040] The food dispensing device also includes a controller (not shown in the figure), which is electrically connected to the drive motors of conveyor 6, conveyor chain 3, and conveyor chain 5. The controller is a programmable logic controller or a microcontroller.

[0041] The controller controls the coordinated operation of each component according to the following timing sequence: First, the conveyor 6 and conveyor chain 3 are started, causing the conveyor 6 to transport biscuits to the receiving plate 404. At the same time, the conveyor chain 3 drives the lever 301 to move towards the component 4. When the lever 301 moves to below the retraction position 402, the controller records the current position signal of the lever 301. This signal is obtained through an encoder or proximity switch installed on the shaft of the conveyor chain 3. According to the position signal of the lever 301, the controller controls the start and stop of the conveyor 6 to ensure that a predetermined number of biscuits are stacked on the receiving plate 404 before each lever 301 reaches the retraction position 402. After the lever 301 passes through the retraction position 402, it pushes the biscuits on the receiving plate 404 to the unloading plate 405. The biscuits slide down the unloading plate 405 to the conveyor chain 5. At the same time, the controller controls the conveyor chain 5 to operate at a speed higher than that of the conveyor chain 3, so that the biscuits are quickly sent away from the unloading area after falling into the conveyor chain 5, avoiding interference with the subsequently falling biscuits.

[0042] The controller is equipped with an operation panel (not shown in the figure), which includes numeric input keys and a display screen. The operator inputs the required number of biscuits to be stacked through the operation panel. The controller automatically calculates and controls the pause time of the conveyor 6 or the operating frequency of the baffle based on the input value, thereby realizing the rapid switching of different quantitative requirements.

[0043] The speed difference between conveyor chain 3 and conveyor chain 5 is independently controlled by a controller. Conveyor chain 3 is driven by a first motor, and conveyor chain 5 is driven by a second motor. The controller outputs pulse signals of different frequencies or different analog voltage values ​​to the first and second motors respectively, so that the speed of the second motor is higher than that of the first motor. The speed difference ranges from 1.2 to 1.8 times, that is, the linear speed of conveyor chain 5 is 1.2 to 1.8 times that of conveyor chain 3, to ensure that the biscuits can be carried away in time after falling from the feed plate 405 onto conveyor chain 5. At the same time, the lever 301 produces a slight oscillating and tidying effect on the stacked biscuits during the conveying process, improving the neatness of the biscuit stack.

[0044] A first positioning sensor (not shown in the figure) is installed above the horizontal section of the receiving plate 404, and a second positioning sensor (not shown in the figure) is installed at the outlet of the discharge plate 405. The first positioning sensor is used to detect whether the receiving plate 404 is filled with a predetermined number of cookies. When the stacking height or quantity is detected to be up to standard, a push permission signal is sent to the controller. The second positioning sensor is used to detect whether the cookies have fallen smoothly from the discharge plate 405 to the conveyor chain 5. If no cookies are detected falling within a preset time, the controller issues an alarm signal and suspends the operation of the equipment, waiting for the operator to check and troubleshoot the fault.
