Abstract
Description
Technical Field
[0001] This utility model relates to the field of biscuit packaging equipment technology, and in particular to a biscuit dispensing machine. Background Technology
[0002] In the packaging process after the cookies are made, the cookies from the production line need to be sorted according to packaging requirements. The required number of cookie layers in each bag is determined before they are sent to the packaging machine for smaller packaging. In traditional packaging production, this work is usually done manually, requiring a large workforce. Furthermore, manually stacked cookies are not very neat, which affects the packaging quality and increases production costs.
[0003] Currently, biscuit sorting equipment is generally used to solve the above-mentioned biscuit sorting problem. Although it can neatly sort the layers of biscuits, it also has certain problems. When the biscuits are pushed forward onto the conveyor belt after sorting, the pusher head used to push the biscuits only moves in a straight line. It pushes the biscuits forward onto the conveyor belt and then pulls them back in the opposite direction. When multiple layers of biscuits need to be pushed out at the same time, the biscuits above the pusher head that are ready to be pushed out in the next cycle will fall freely down to the support plate at the bottom of the biscuit chute after being pulled back. This process is extremely unstable and the biscuits are prone to tipping over, which seriously affects the packaging quality and packaging efficiency. Moreover, the biscuits will also break and be damaged while falling, affecting product quality and increasing production costs. Utility Model Content
[0004] The main technical problem solved by this utility model is to provide a biscuit dropping machine that can make the biscuit dropping process smooth, which is conducive to improving packaging quality and efficiency and reducing production costs.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0006] A pancake-making machine, comprising:
[0007] The cookie drop chute has a tray at the bottom for supporting the cookies;
[0008] The pusher head is located on one side of the bottom of the cake dropping chute;
[0009] The reciprocating drive mechanism is connected to the pusher head, which drives the pusher head to reciprocate in the vertical direction in the order of forward, downward, backward and upward. When the pusher head pushes forward, it pushes the biscuit unit to be pushed onto the conveyor belt. When it moves downward, it causes the biscuit above the pusher head to fall onto the tray at the bottom of the biscuit drop chute.
[0010] Furthermore, the tray is composed of support plates extending from the bottom two sides of the biscuit drop chute towards the center. The two sides of the biscuit are supported on the two support plates, and the space between the two support plates is a clearance space.
[0011] Furthermore, the pusher head has a frame-shaped structure and a supporting surface for supporting the biscuit above.
[0012] Furthermore, the biscuit dropping chute consists of side guards and a back plate. At the bottom of the biscuit dropping chute, there is a tray for supporting the biscuit. A baffle is installed on the guards, and an adjusting plate is installed at the bottom of the baffle. The baffle at least partially covers the back plate. The baffle and the guards are installed in a radially adjustable manner to limit the distance between the baffle and the back plate to match the size of the biscuit. The adjusting plate and the baffle are installed in a height adjustable manner to limit the thickness of the biscuit pushed out at one time.
[0013] Furthermore, the reciprocating drive mechanism includes a lifting drive mechanism and a horizontal drive mechanism. The horizontal drive mechanism is fixedly connected to the pusher head, and the horizontal drive mechanism and the pusher head are driven to move up and down by the lifting drive mechanism.
[0014] Furthermore, the horizontal drive mechanism includes a cylinder, which is fixed to the top of the lifting drive mechanism, and the telescopic guide rod of the cylinder is fixed to the pusher head.
[0015] Furthermore, the lifting drive mechanism includes,
[0016] The servo motor is mounted on a motor mount.
[0017] A lifting plate, wherein the horizontal drive mechanism is fixedly installed above the lifting plate;
[0018] The lifting mechanism has a fixed end connected to the output end of the servo motor and a lifting end fixed to the lifting plate, thereby driving the lifting plate to complete the lifting motion.
[0019] Furthermore, the lifting mechanism is a lifting screw pair, consisting of a screw and a nut sleeve. The lifting plate is a frame structure consisting of at least a top plate, a bottom plate, and a side plate. The horizontal drive mechanism is installed on the top plate of the lifting plate. The nut sleeve is fixed above the bottom plate of the lifting plate. The output end of the servo motor is fixedly connected to the screw. The screw passes upward through the bottom plate of the lifting plate and is threadedly connected to the nut sleeve.
[0020] Furthermore, the lifting drive mechanism also includes a linear guide rail pair extending in the vertical direction, which is fixed to the lifting plate and the frame plate respectively, and the top plate of the frame plate is fixedly connected to the bottom of the cake dropping chute.
[0021] Furthermore, the reciprocating drive mechanism also includes a biscuit unit layer detection device, which is connected to a controller. The controller is connected to a lifting drive mechanism, and the controller adjusts the lifting height of the pusher head in each cycle through the lifting drive mechanism.
[0022] In summary, the biscuit dropping machine provided by this utility model, by changing the movement trajectory of the pusher head from the single lateral movement in the prior art to a cyclical reciprocating motion of forward, downward, backward, and upward, can not only accurately push the sorted biscuit units onto the conveyor belt, but also use the pusher head to support the biscuits above and move them downward together, so that the biscuits can fall smoothly onto the tray at the bottom of the dropping chute. This avoids the possibility of the biscuits tipping over and breaking during the falling process, ensuring product quality, reducing production costs, and also significantly improving packaging quality and packaging efficiency.

Detailed Implementation
[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0037] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0039] like Figures 1 to 3 As shown, this utility model provides a cake-dispensing machine, including a cake-dispensing chute 1, a pusher head 2, and a reciprocating drive mechanism 3. The cake-dispensing chute 1, the pusher head 2, and the reciprocating drive mechanism 3 are all installed on one side of a conveyor belt (not shown in the figure).
[0040] The biscuit drop chute 1 consists of two side guard plates 11 and a back plate 12 between the two guard plates 11. At the bottom of the biscuit drop chute 1 is a tray 4 for supporting the biscuits. Biscuits placed from above the biscuit drop chute 1 fall downwards onto the tray 4. A pusher head 2 is located on one side of the bottom of the biscuit drop chute 1. A reciprocating drive mechanism 3 is connected to the pusher head 2, and the reciprocating drive mechanism 3 drives the pusher head 2 to reciprocate in a vertical direction in the order of forward, downward, backward, and upward.
[0041] Specifically, when the reciprocating drive mechanism 3 drives the pusher head 2 forward, it pushes the biscuit unit to be pushed onto the conveyor belt. The biscuit unit includes several layers of biscuits determined according to packaging requirements. At this time, the height of the pusher head 2 is the same as the height of the biscuit unit to be pushed. Each time the pusher head 2 pushes forward, it pushes the several layers of biscuits to be pushed onto the conveyor belt. While the pusher head 2 is pushing forward, the biscuits that do not belong to the biscuit unit to be pushed will be directly supported on the support surface 21 above the pusher head 2. When the pusher head 2 moves downward after being pushed forward to the position, it will move the biscuits supported on the pusher head 2 downward with the pusher head 2 and finally fall onto the tray 4 at the bottom of the biscuit drop chute 1. The reciprocating drive mechanism 3 then moves the pusher head 2 backward and then upward to the initial position to complete one cycle. After being pulled back, since the biscuits have fallen steadily onto the tray 4, the biscuits will not fall or break due to the retraction of the pusher head 2. This motion cycle repeats continuously, intermittently pushing biscuit units that meet the packaging layer requirements onto the conveyor belt. In this embodiment, the movement of the pusher head 2 ensures product quality, reduces production costs, and significantly improves packaging quality and efficiency.
[0042] In this embodiment, preferably, a baffle 6 is further installed on the biscuit drop chute 1. The baffle 6 at least partially covers the top of the back plate 12. The baffle 6 and the guard plate 11 are installed with a radially adjustable structure (i.e., the width direction of the guard plate 11) to limit the distance between the baffle 6 and the back plate 12 to match the size of the biscuit. This allows for easy adjustment of the distance between the baffle 6 and the back plate 12 according to the size of the biscuit, thereby ensuring that the biscuit can slide smoothly in the biscuit drop chute 1 and be stacked on the bottom tray 4. Specifically, the baffle 6 is connected to the guard plate 11 through a connecting plate 7.
[0043] In this embodiment, it is further preferred that the baffle 6 is divided into left and right parts, and the two baffles 6 are respectively fixedly connected to the corresponding side guard plate 11 by two connecting plates 7. The connecting plates 7 are welded to the baffle 6 and then fixed to the guard plate 11 by screws. Multiple mounting holes (not shown in the figure) are provided on the connecting plates 7 along the width direction of the guard plate 11. Correspondingly, mounting holes are also provided on the guard plate 11. By using the different mounting holes on the connecting plates 7 and the mounting holes on the guard plate 11 for fixed connection, the distance between the baffle 6 and the back plate 12 can be adjusted according to the size of the biscuit.
[0044] In this embodiment, it is further preferred that an adjusting plate 8 is installed at the bottom of the baffle 6. The adjusting plate 8 and the baffle 6 are installed with an adjustable structure in the height direction to limit the thickness of the biscuit pushed out at one time. This ensures that the pusher head 2 can smoothly push out the correct number of biscuit layers from the biscuit drop chute 1. Specifically, the adjusting plate 8 is provided with an elongated oval mounting hole extending in the height direction. The adjusting plate 8 is fixedly connected to the baffle 6 at any height position by screws.
[0045] In this embodiment, it is further preferred that the upper surface of the pallet 4 and the upper surface of the conveyor belt are on the same plane. This ensures that when the pusher head 2 pushes forward, the biscuit unit can fall smoothly onto the conveyor belt and will not fall over during the pushing process, which is conducive to further improving packaging quality and packaging efficiency.
[0046] like Figure 2 As shown, in this embodiment, preferably, the tray 4 has a clearance space to avoid the pusher head 2, so as to provide movement space for the pusher head 2 to move downward. More preferably, the tray 4 is composed of support plates 41 extending from the bottom sides of the biscuit drop chute 1 towards the center, and the two sides of the biscuit are supported on the two support plates 41, and the space between the two support plates 41 is the clearance space.
[0047] Correspondingly, an opening 5 with a bottom open section is provided on the back plate 12 at the bottom of the cake dropping chute 1, through which the pusher head 2 extends forward when pushed forward. The height of the opening 5 must be such that the pusher head 2 can pass through smoothly even when it is at its highest height.
[0048] like Figures 1 to 3 As shown in the figure, in this embodiment, the pusher head 2 preferably adopts a frame-shaped structure, which is preferably a rectangular frame structure as shown in the figure. This can ensure the stability of the pusher head 2 during movement. Of course, the frame-shaped structure can also adopt a simple inverted L-shaped or C-shaped structure, as long as the upper surface of the pusher head 2 can serve as the support surface 21 for supporting the upper biscuit, and the front side can push a multi-layered biscuit unit at the same time. After the pusher head 2 is pushed forward, the upper biscuit naturally falls onto the support surface 21 of the pusher head 2.
[0049] like Figures 1 to 3 As shown, in this embodiment, the reciprocating drive mechanism 3 includes a lifting drive mechanism 31 and a horizontal drive mechanism 32. The horizontal drive mechanism 32 is fixedly connected to the pusher head 2. The horizontal drive mechanism 32 and the pusher head 2 are driven by the lifting drive mechanism 31 to move up and down simultaneously.
[0050] In this embodiment, it is further preferred that the lifting drive mechanism 31 includes a servo motor 311, a lifting plate 312, and a lifting mechanism. The lifting mechanism preferably employs a lifting lead screw pair, which consists of a lead screw 313 and a nut sleeve 314. Of course, other transmission mechanisms can also be used, such as gear and rack transmission mechanisms, as long as they can achieve the lifting movement of the lifting plate 312. Using a servo motor 311 facilitates precise control of the lifting amplitude and speed of the pusher head 2.
[0051] The servo motor 311 is mounted on the motor mount 33, which is fixed to the frame plate 34. In this embodiment, because the lifting mechanism uses a lifting screw pair, the motor mount 33 preferably adopts an inverted L-shaped structure. The servo motor 311 is suspended below the horizontal mounting plate of the motor mount 33, and the output end of the servo motor 311 extends upward through the horizontal mounting plate of the motor mount 33. The vertical mounting plate of the motor mount 33 is fixedly mounted to the frame plate 34 with bolts. Multiple elongated oval mounting holes are provided on the vertical mounting plate of the motor mount 33 to facilitate adjustment of the mounting height of the servo motor 311.
[0052] The support plate 34 is fixedly installed below the cake dropping chute 1 and placed on one side of the conveyor belt. The top of the support plate 34 is fixedly connected to the bottom of the cake dropping chute 1 by welding. The top of the support plate 34 has a notch 35 that provides movement space for the pusher head 2. The notch 35 is correspondingly set with the opening 5 at the bottom of the cake dropping chute 1, forming the movement space of the pusher head 2 when it moves up and down.
[0053] In this embodiment, the lifting plate 312 is a frame structure composed of at least a top plate 3121, a bottom plate 3122, and a side plate 3123. This frame structure enhances the overall structural strength of the lifting plate 312 and provides the necessary mounting interfaces for the lifting screw pair and the horizontal drive mechanism 32. The horizontal drive mechanism 32 is fixed to the top plate 3121. The nut sleeve 314 (i.e., the lifting end) in the lifting screw pair is fixed above the bottom plate 3122. One end (i.e., the fixed end) of the screw 313 is fixedly connected to the output end of the servo motor 311. The screw 313 passes upward through the bottom plate 3122 of the lifting plate 312 and is threadedly connected to the nut sleeve 314. When the output end of the servo motor 311 rotates forward and backward, it drives the screw 313 to rotate forward and backward. Simultaneously, the nut sleeve 314 moves up and down along the screw 313, and under the action of the nut sleeve 314, the lifting plate 312 moves upward or downward to complete the lifting motion.
[0054] In this embodiment, the horizontal drive mechanism 32 is further preferably an air cylinder 321. The air cylinder 321 is fixed to the lifting plate 312 via a mounting base 322, and the mounting base 322 and the lifting plate 312 are fixedly connected by bolts. The front end of the telescopic guide rod (not shown in the figure) of the air cylinder 321 is fixed to the pusher head 2. The telescopic guide rod of the air cylinder 321 drives the pusher head 2 to move forward or backward. The horizontal drive mechanism 32 can also adopt other linear drive mechanisms in the prior art.
[0055] In this embodiment, the action of the control cylinder 321 can be used to control the pushing stroke of the pusher head 2 in the horizontal direction, so as to accurately push the biscuit unit onto the conveyor belt.
[0056] This embodiment also provides another implementation method, in which a stroke control switch is also included in the horizontal drive mechanism 32, which is installed on one side of the pusher head 2. The stroke control switch moves synchronously with the pusher head 2. When the stroke control switch moves forward and touches the cake dropping chute 1, the stroke control switch is activated, indicating that the pusher head 2 has run to the designated position, and controls the servo motor 311 to move, driving the pusher head 2 to move downward. The servo motor 311 controls the downward and upward movement distance of the pusher head 2.
[0057] In this embodiment, the lifting drive mechanism 31 further includes a linear guide pair 36 extending in the vertical direction. The linear guide pair 36 includes a linear guide 361 and a slider 362, which are respectively fixed to the side plates 3123 of the frame plate 34 and the lifting plate 312. The linear guide pair 36 can stabilize the sliding and ensure the sliding trajectory, ensuring that the pusher head 2 can accurately push the biscuit unit in front.
[0058] In this embodiment, a biscuit layer detection device (not shown in the figure) is further included, which is connected to the controller. The controller is connected to the lifting drive mechanism 31, and the controller adjusts the lifting height of the pusher head 2 through the lifting drive mechanism 31. The biscuit layer detection device preferably uses a thickness sensor. The controller stores or sets the correspondence between the total thickness of the biscuit unit and the number of biscuit layers in the biscuit unit in advance. For example, according to the packaging requirements, four biscuits are packaged in a packaging bag. The total thickness of the four biscuits is set in advance according to the thickness of each biscuit. The thickness sensor detects the thickness of the biscuit unit in real time. The controller compares the detected value with the set value and adjusts the lifting height of the pusher head 2 at any time according to the comparison result. That is, the lifting height of the pusher head 2 is fine-tuned each time to ensure that the pusher head 2 pushes forward a biscuit unit that meets the packaging requirements and can ensure a smooth push.
[0059] The steps for using this pancake dispenser are as follows:
[0060] 1. Workers put a certain number of cookies to be packaged into the cookie dropping chute 1 through the manual feeding port (not shown in the figure). The cookies fall down along the cookie dropping chute 1 and are neatly stacked in the cookie dropping chute 1, with the bottom of the cookies supported on the tray 4.
[0061] In this step, during the initial feeding, workers need to support the bottom of the biscuit with their hands to prevent it from breaking during the fall. After normal production begins, there are two feeding methods: The first is that workers continuously place biscuits into the biscuit drop chute 1, leaving a certain height of biscuits above the tray 4. The second is that workers continuously place biscuits onto the conveyor belt connected to the biscuit drop chute 1, and the conveyor belt continuously feeds the biscuits into the biscuit drop chute 1.
[0062] 2. After the reciprocating drive mechanism 3 is started, the thickness sensor detects the thickness of the biscuit unit in real time. The controller compares the detected value with the set value and adjusts the rising height of the pusher head 2 at any time according to the comparison result. After the pusher head 2 reaches the rising height, the horizontal drive mechanism 32 pushes the pusher head 2, and the pusher head 2 moves forward to push the biscuit unit that meets the specified number of layers onto the conveyor belt.
[0063] 3. After the pusher head 2 moves forward to the designated position, the cookies that do not belong to the cookie unit being pushed will be directly supported on the support surface 21 above the pusher head 2. Control the pusher head 2 to move downward, and the pusher head 2 will drive the cookies above to move downward together, so that the cookies finally fall onto the tray 4 at the bottom of the cookie drop chute 1.
[0064] 4. After the pusher head 2 moves downward to the designated position, it is then pulled back and moved upward to the initial position. During this process, the rising height of the pusher head 2 is adjusted again according to the thickness detection results. After reaching the designated height position, the pusher head 2 is pushed forward to continue the next cycle.
[0065] 5. In each cycle, each biscuit unit is arranged intermittently on the conveyor belt and moves forward with the conveyor belt. Finally, each biscuit unit is packaged at the packaging machine.
[0066] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
