Description

Technical Field

[0001] This utility model relates to the field of chopstick misalignment separation technology, specifically a chopstick sharpening machine and chopstick misalignment separation device. Background Technology

[0002] Chopsticks are an extremely common dining utensil in daily life, and disposable chopsticks are widely used due to their low cost and convenience. During the production process, disposable chopsticks need to be separated to prevent multiple chopsticks from entering the sharpening mechanism simultaneously, which would result in uneven cutting force and inconsistent taper of the finished product.

[0003] The prior art, disclosed in CN211593106U, provides a chopsticks sharpening machine with a chopsticks misalignment separation device. This device includes a chopsticks separation device body. A funnel is fixedly mounted on the upper inner side of the body, and a baffle is fixedly mounted on the lower inner side of the funnel. A conveying roller is axially mounted on the inner side of the baffle, and a third pulley is fixedly mounted on one end of the conveying roller. A receiving groove is fixedly mounted on the lower inner side of the body, and a drive motor is fixedly mounted on one side of the receiving groove. A second pulley is driven on one side of the drive motor. A square sliding top rod is positioned corresponding to the front end of one of the grooves in the double-groove chopsticks conveying groove, precisely corresponding to the chopsticks inside the conveying roller. Each movement causes one chopstick to be pushed against by the square sliding top rod, separating it. The separated chopstick falls into the receiving groove and is discharged through the outlet. This design is more reasonable and optimized, meeting people's needs.

[0004] In the aforementioned patent, chopsticks are mainly fed into the conveying roller through a funnel for separation and transfer. However, since this method of feeding chopsticks lacks a squeezing and limiting structure, a large number of chopsticks will rush into the conveying roller together, making it impossible for chopsticks to enter the groove of the conveying roller individually. Consequently, it is impossible to stably perform the chopsticks separation operation, thus reducing the stability of the chopsticks transmission of the chopsticks separation device. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a chopsticks sharpening machine and chopsticks misalignment separation device, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chopsticks-sharpening machine chopsticks misalignment separation device, comprising a device body, a transmission component for chopstick transmission installed on one side of the device body, an anti-drop component for preventing chopsticks from falling fixedly installed on the top of the device body near the transmission component, and pushing components for squeezing and pushing chopsticks installed on both sides of the device body away from the anti-drop component. A controller is fixedly installed on the device body on a side different from the side where the pushing components are located, and the controller is used to control the electronic components within the chopsticks misalignment separation device. The device body includes a support body, and the support body has an inclined surface on the side near the pushing component for chopsticks to roll off. The inclined surface on the side near the pushing component allows chopsticks to automatically fall off during use, improving the convenience for the user during operation.

[0007] Furthermore, the support body has mounting frames fixedly installed on both sides of one end near the inclined surface. The pushing assembly includes multiple spring columns fixedly installed on the inner wall of the mounting frames. A support strip is fixedly installed on the end of each spring column away from the inner wall of the mounting frame. The support strip is located between the spring column and the outer wall of the support body. A shaft is fixedly installed on the end of the support strip away from the spring column, penetrating the upper end of the support body. A pushing strip for contacting the chopsticks is fixedly installed on the end of the shaft away from the support strip. The spring columns are used to constantly push the pushing strip, causing the pushing strip to concentrate the chopsticks. This continuous pushing of the spring columns to concentrate the pushing strip on the chopsticks allows the chopsticks moving inside the chopsticks-sharpening machine's chopsticks-misalignment separation device to be operated in a concentrated manner during use, improving the accuracy of chopstick movement within the device.

[0008] Furthermore, the end of the push bar away from the shaft has multiple grooves, and a pressing component for squeezing chopsticks is slidably mounted on the push bar in the grooves. This sliding mounting of the pressing component on the push bar allows the chopsticks in the chopsticks-sharpening machine to be squeezed up and down during use, ensuring that the chopsticks can only move in one direction, thus improving the practicality of the chopsticks-sharpening machine's chopsticks-sharpening and separating device.

[0009] Furthermore, the transmission assembly includes a frame fixedly mounted on a support body, a motor fixedly mounted inside the frame, a control box of the motor electrically connected to the controller, a rotating shaft fixedly connected to the output end of the motor, and a wheel assembly for placing chopsticks fixedly mounted at the center of the rotating shaft.

[0010] Furthermore, the wheel assembly includes a wheel fixedly mounted on a rotating shaft, and the outer surface of the wheel has multiple expanding grooves for storing individual chopsticks. The presence of these grooves ensures that only one chopstick can enter at a time for transmission, thus improving the practicality of the chopstick separation device in the chopstick sharpening machine.

[0011] Furthermore, the anti-drop component includes a fixed plate fixedly mounted on the support body, an electric push rod fixedly installed at the center of the fixed plate, the electric push rod being electrically connected to the controller, and an anti-drop arc plate for preventing chopsticks from falling from the transmission component being fixedly connected to the telescopic end of the electric push rod.

[0012] Furthermore, limiting strips for limiting the chopsticks are fixedly installed on both sides of the inclined surface near the transmission component. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features pushing components on both sides of the inclined surface where chopsticks slide down. As the chopsticks move along the inclined surface, they are squeezed up and down and pushed from both sides by the pushing components, allowing the chopsticks to slide down into the gradually expanding groove of the wheel assembly for transmission in a single and stable manner. This improves the quality and stability of the single transmission of chopsticks in the chopsticks sharpening machine's chopsticks misalignment separation device. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application provides a further detailed description of a chopsticks sharpening machine and chopsticks misalignment separation device, comprising a device body 1. A transmission component 5 for chopstick transmission is mounted on one side of the device body 1. An anti-drop component 2 for preventing chopsticks from falling is fixedly mounted on the top of the device body 1 near the transmission component 5. Pushing components 3 for squeezing and pushing chopsticks are mounted on both sides of the device body 1 away from the anti-drop component 2. A controller 4 is fixedly mounted on the side of the device body 1 different from the side where the pushing components 3 are located. The controller 4 controls the electronic components within the chopsticks misalignment separation device. The device body 1 includes a support body 11. 11 has an inclined surface 13 on the side near the pushing component 3 for the chopsticks to roll off. The support body 11 has mounting frames 12 fixedly installed on both sides of one end near the inclined surface 13. The pushing component 3 includes multiple spring posts 35 fixedly installed on the inner wall of the mounting frames 12. A support bar 36 is fixedly installed at the end of the spring post 35 away from the inner wall of the mounting frame 12. The support bar 36 is located between the spring post 35 and the outer wall of the support body 11. A shaft 34 is fixedly installed at the end of the support bar 36 away from the spring post 35. The shaft 34 penetrates the upper end of the support body 11. The end of the shaft 34 away from the support bar 36 is fixed... A pusher bar 33 for contacting chopsticks is installed, and a spring column 35 continuously pushes the pusher bar 33 to concentrate the chopsticks. Multiple grooves 32 are provided at the end of the pusher bar 33 away from the shaft 34. A pressing component 3 for squeezing the chopsticks is installed on the pusher bar 33, sliding on the grooves 32. The transmission component 5 includes a frame 53 fixedly mounted on the support body 11. A motor 54 is fixedly installed inside the frame 53. The control box of the motor 54 is electrically connected to the controller 4. A rotating shaft 52 is fixedly connected to the output end of the motor 54. A pressing component for squeezing the chopsticks is fixedly installed at the center of the rotating shaft 52. The wheel assembly 51 for placing chopsticks includes a rotating wheel 512 fixedly mounted on a rotating shaft 52. The outer surface of the rotating wheel 512 has multiple gradually expanding grooves 511 for storing a single chopstick. The anti-drop assembly 2 includes a fixing plate 23 fixedly mounted on a support body 11. An electric push rod 22 is fixedly mounted at the center of the fixing plate 23. The electric push rod 22 is electrically connected to the controller 4. The telescopic end of the electric push rod 22 is fixedly connected to an anti-drop arc plate 21 for preventing chopsticks from falling from the transmission assembly 5. Limiting strips 15 for limiting the chopsticks are fixedly mounted on both sides of the inclined surface 13 near the end of the transmission assembly 5.

[0025] The controller 4 contains a microcontroller control board, and the control boxes of the electric push rod 22 and the motor 54 are electrically connected to the microcontroller control board inside the controller 4. Therefore, the controller 4 can directly control the operation of the electric push rod 22 and the motor 54. Since the microcontroller control board inside the controller 4 is a common model available on the market, this utility model does not describe it in detail.

[0026] The part of the extrusion strip 31 that contacts the groove 32 is made of rubber, while the part of the extrusion strip 31 that extrudes the chopsticks is made of stainless steel. The two parts are bonded together with an adhesive. Therefore, when the user manually slides the extrusion strip 31 on the groove 32, when the extrusion strip 31 loses external force, the rubber part of the extrusion strip 31 will generate a large friction with the inside of the groove 32, preventing it from falling off and fixing it in the position where no external force is applied. The stainless steel part of the extrusion strip 31 is designed to ensure that the chopsticks can only roll off the inclined surface 13 one by one.

[0027] Since the shaft 34 can move within the support 11, and the push bar 33 and support bar 36 limit its movement, the thrust of the spring column 35 can push the shaft 34 toward the position of the push bar 33 at all times, so that the push bar 33 can push the chopsticks at all times, preventing chopsticks in different positions from falling stably into the expanding groove 511 of the rotating wheel 512.

[0028] The mounting slot 14 of the support body 11 is used to install the transmission component and the chopstick sharpening machine, so that after the chopsticks are separated by misalignment, they can be quickly transmitted through the transmission component and finally enter the chopstick sharpening machine for the corresponding sharpening operation.

[0029] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the chopsticks sharpening machine's chopsticks misalignment separation device are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the diagram. Before use, the user adjusts the height of the extrusion strip 31 according to the specific diameter of the chopsticks. When adjusting the height of the extrusion strip 31, the user only needs to manually move the extrusion strip 31 up and down within the groove 32 of the pusher strip 33. The friction between the groove 32 and the rubber part of the extrusion strip 31 fixes the extrusion strip 31 within the groove 32 of the pusher strip 33. The user can also adjust the length of the shaft 34 and the spring column 35 according to the specific length of the chopsticks, ensuring that when the chopsticks slide on the inclined surface 13, they can only slide one at a time along the inclined surface. 13 slides into the gradually expanding groove 511 of the rotating wheel 512. At this time, the controller 4 drives the wheel assembly 51 to rotate slowly. During the rotation of the wheel assembly 51, the anti-arc plate 21 controlled by the electric push rod 22 can block the chopsticks on the wheel assembly 51, so that the chopsticks on the wheel assembly 51 will not fall when they are below the anti-arc plate 21. When the wheel assembly 51 rotates to the side away from the inclined surface 13, they will fall. At this time, the subsequent transmission structure and the chopstick sharpening machine can perform the sharpening operation on the chopsticks one by one. Through the above structure, the chopsticks misalignment separation device of the chopstick sharpening machine can be used to squeeze and push the chopsticks, so that the chopsticks can fall steadily one by one along the inclined surface 13 into the gradually expanding groove 511 of the rotating wheel 512 and perform the corresponding subsequent operations, which greatly improves the stability and practicality of the chopsticks misalignment separation device of the chopstick sharpening machine.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
