DETAILED DESCRIPTION
[0020] The following is combined with Figure 1-Figure 2 This application is described in further detail.
[0021] The present application embodiment discloses a desktop straw machine. Figure 1 and Figure 2 The desktop straw machine includes a base 1, which is horizontally arranged and in the shape of a rectangular parallelepiped. The base 1 is used as the base of the desktop straw machine and is placed on the desktop. At the same time, a storage box 2, a forming mold 4 and a push cylinder 3 are arranged on the base 1. The storage box 2 is used to store a plurality of stacked papers. The push cylinder 3 is located on one side of the storage box 2 and is used to realize the discharge of the paper. The forming mold 4 is located on the other side of the storage box 2 and is used to form the paper.
[0022] Specifically, the storage box 2 is arranged in a rectangular shape, and the storage box 2 can be slidably arranged on the upper surface of the base 1 in the horizontal direction. A plurality of material bins 21 are arranged inside the storage box 2. In the present embodiment, there are preferably three material bins 21, and the three material bins 21 are arranged at intervals in the horizontal direction. The three material bins 21 are respectively used to store different types of paper. Correspondingly, three discharge ports 22 are correspondingly opened on the side wall of the storage box 2, and the three discharge ports 22 are arranged at intervals in the horizontal direction. Each discharge port 22 is connected to a corresponding one of the material bins 21 and is located on the bottom side of the material bin 21.
[0023] Correspondingly, the forming molds 4 are provided with several groups. In the present embodiment, the forming molds 4 are preferably provided in three groups. The three groups of forming molds 4 are located on one side of the storage box 2. A rotating frame 11 is rotatably supported on the top of the base 1. The axis of the rotating frame 11 is horizontally arranged and arranged along the length direction of the base 1. At the same time, three connecting rods 111 are fixed to the outer periphery of the rotating frame 11. The angle between two adjacent connecting rods 111 is 120°. The three groups of forming molds 4 are respectively and sequentially installed on the three connecting rods 111. In the present embodiment, the three groups of forming molds 4 have different sizes, but the same components, so as to adapt to different types of paper. Among them, the forming mold 4 located at the top corresponds to the processing station of the desktop straw machine in the present application.
[0024] In an embodiment of the present application, a control component 5 for controlling the movement of the material storage box 2 and the switching of the forming modules is provided on the base 1, which is specifically used to control the sliding of the material storage box 2 so that one of the material bins 21 is connected with the forming mold 4, and also simultaneously controls the rotation of the rotating frame 11 so that one group of the forming molds 4 is connected with the material storage box 2.
[0025] Therefore, the control component 5 controls the storage box 2 to slide in the horizontal direction so that one of the bins 21 is connected to the forming mold 4. Since there are three bins 21 inside the storage box 2, each bin 21 stores different types of paper. By controlling the sliding of the storage box 2, different paper types can be switched to meet the production requirements of different types of straws.
[0026] Meanwhile, three connecting rods 111 are fixed on the rotating frame 11, and a group of forming molds 4 are installed on each connecting rod 111, and the angle between adjacent connecting rods 111 is 120°. The control component 5 simultaneously controls the rotation of the rotating frame 11, so that one group of forming molds 4 is connected with the storage box 2. Since the three groups of forming molds 4 have different sizes but the same components, this design enables the device to automatically switch to the appropriate forming mold 4 according to the type of paper selected to produce straws of different sizes or characteristics.
[0027] Correspondingly, the control component 5 includes a control motor 51, a first transmission gear 52 and a first transmission rack 53. The control motor 51 is installed on the base 1. The output shaft of the control motor 51 is arranged along the width direction of the base 1. The first transmission gear 52 is connected to the output shaft of the control motor 51. The first transmission rack 53 is meshed with the first transmission gear 52 and slides in the horizontal direction. The first transmission rack 53 is fixed to the storage box 2.
[0028] Specifically, two bevel gears 12 are rotatably carried on the base 1, and the two bevel gears 12 are meshed with each other. A pulley transmission mechanism 13 is provided between one of the bevel gears 12 and the output shaft of the control motor 51, and one of the pulleys of the pulley transmission mechanism 13 is coaxially fixed with the output shaft of the control motor 51, and the other pulley of the pulley transmission mechanism 13 is coaxially fixed with one of the bevel gears 12. In addition, the first transmission gear 52 is coaxially fixed with the other bevel gear 12.
[0029] Therefore, when the control motor 51 is started, the power is transmitted to the bevel gear 12 through the pulley transmission mechanism 13, and then the first transmission gear 52 is driven to rotate through the bevel gear 12. The rotation of the first transmission gear 52 causes the first transmission rack 53 to slide in the horizontal direction, thereby driving the storage box 2 to slide, thereby achieving precise connection between different material bins 21 and the forming mold 4.
[0030] In addition, a worm 511 is coaxially fixed to the output shaft of the control motor 51, and a worm wheel 112 is coaxially arranged on the rotating frame 11. The worm 511 and the worm wheel 112 are meshed with each other. When the control motor 51 is started, the worm 511 is synchronously driven to rotate, so that the worm wheel 112 meshed with the worm 511 rotates, and then the rotating frame 11 is driven to rotate, and then the molding die 4 is replaced. Among them, due to the low speed ratio characteristics of the worm wheel 112 and the worm 511, a good self-locking function is also provided, ensuring the accuracy and safety of the replacement process of the molding die 4.
[0031] On the other hand, the desktop straw machine in the present application also includes a control system, which consists of a programmable logic controller, an order processing unit, a communication network unit and a human-computer interaction interface. The order information processing unit parses the order information and sends the key parameters to the programmable logic controller. The programmable logic controller generates a control signal according to the control logic and sends it to the control motor 51 through the I / O module. The human-computer interaction interface displays the production status. The operator can input production parameters or handle abnormal situations through the human-computer interaction interface and interact with the programmable logic controller.
[0032] In combination with the above content, the embodiments of the present application are described below.
[0033] First, the order information processing unit receives and parses the order information, and extracts key parameters therefrom, such as straw type, size, quantity, etc. These parameters are crucial for determining the required silo 21 and forming mold 4.
[0034] At the same time, the analyzed key parameters are sent to the programmable logic controller. The programmable logic controller generates corresponding control signals according to the preset control logic. These signals include instructions for switching the silo 21 and the forming mold 4 to match the type of straw on the order.
[0035] Furthermore, the programmable logic controller sends a control signal to the control motor 51 through the I / O module, and the control motor 51 is started according to the signal to drive the worm gear 112 and the worm 511 mechanism, thereby realizing automatic switching between the silo 21 and the molding die 4.
[0036] In addition, operators can monitor production status in real time, input production parameters, or intervene in abnormal situations through the human-computer interaction interface. The interface displays the current production progress, silo and mold status, and any potential fault information, ensuring that operators can respond in time to keep the production process smooth.
[0037] Finally, throughout the entire process, the communication network unit ensures data transmission between various parts of the control system, including real-time updates of order information, control signals, and production status, ensuring the accuracy and timeliness of information.
[0038] On the other hand, the specific structure of the forming mold 4 for realizing paper forming is as follows.
[0039] Specifically, the molding mold 4 includes an inner cylinder 41, an outer cylinder 42 and a hot pressing assembly 43. The outer cylinder 42 is sleeved on the outside of the inner cylinder 41 to form a molding groove 411. The outer wall of the inner cylinder 41 and the inner wall of the outer cylinder 42 are fixedly connected by a connecting block. The diameter of the notch of the molding groove 411 gradually decreases from one end close to the storage box 2 toward the other end. The hot pressing assembly 43 is used to press and fix the overlapping areas on both sides of the paper.
[0040] Furthermore, the hot pressing assembly 43 includes a driving motor 431, a hot pressing roller 432 and a driven roller 433. The driving motor 431 is installed on the outer wall of the outer cylinder 42, the hot pressing roller 432 is rotatably supported on the outer cylinder 42, the hot pressing roller 432 is coaxially fixed with the output shaft of the driving motor 431, the driven roller 433 is rotatably supported on the inner cylinder 41, and the gap formed between the hot pressing roller 432 and the driven roller 433 is located in the molding groove 411.
[0041] Therefore, when the push cylinder 3 pushes a part of the paper into the forming groove 411 through the push plate, the drive motor 431 is started, and its output shaft drives the coaxially fixed hot pressing roller 432 to rotate. The hot pressing roller 432 is located on the outer cylinder 42, and is arranged opposite to the driven roller 433, and the gap formed between the two is just located in the forming groove 411. When the paper passes through the forming groove 411, the cooperation between the hot pressing roller 432 and the driven roller 433 applies pressure to the overlapping areas on both sides of the paper. At the same time, the temperature of the hot pressing roller 432 ensures that the paper can be hot-pressed and bonded, thereby completing the forming of the straw, and also drives the paper to move toward the notch of the forming groove 411 to deliver the paper. This process, under the guidance of the gradually decreasing notch diameter of the forming groove 411, ensures that the paper can accurately form the required straw shape, and the precise control of the hot pressing assembly 43 ensures the stable production of the straw.
[0042] On the other hand, an isolation cover 6 is provided on the base 1, and the isolation cover 6 is arranged on the outside of the material storage box 2, the forming mold 4, the pushing cylinder 3 and the control component 5. The side wall of the isolation cover 6 is provided with an inspection door 61, and the inspection door 61 is hinged to the isolation cover 6. The side wall of the isolation cover 6 is provided with a through opening 62, and the through opening 62 is connected to the groove of the forming groove 411.
[0043] Therefore, the isolation cover 6 can effectively isolate the external environment from the interference of the storage box 2, the forming mold 4, the push cylinder 3 and the control component 5, ensuring that these key components operate in a clean and stable environment, improving the stability of the production process and the product quality. Secondly, the side wall of the isolation cover 6 is provided with a through hole 62, which is connected to the notch of the forming groove 411, ensuring that the formed straw can be smoothly output from the through hole 62, while preventing dust or debris from escaping during the production process, and keeping the work area clean.
[0044] Furthermore, a cover plate 63 is hinged on the inner wall of the isolation cover 6, and the cover plate 63 is used to seal the opening 62. A transmission assembly 7 is arranged between the cover plate 63 and the pushing cylinder 3. The transmission assembly 7 includes a lifting ring 72 and a push rod 71. The lifting ring 72 is hung on the top inner wall of the isolation cover 6, and the push rod 71 is fixed to the side wall of the piston rod of the pushing cylinder 3. The push rod 71 movably passes through the lifting ring 72, and one end of the push rod 71 is hinged to the cover plate 63.
[0045] Therefore, when the piston rod of the push cylinder 3 extends, the push rod 71 fixed on its side wall moves accordingly, and the push rod 71 movably penetrates the hanging ring 72, and one end of the push rod 71 is hinged to the cover plate 63, thereby driving the cover plate 63 to rotate around the hinge point, opening the opening 62 on the isolation cover 6, so that the push cylinder 3 can push out the formed straw. When the piston rod retracts, the reverse movement of the push rod 71 prompts the cover plate 63 to close the opening 62, effectively preventing external impurities from entering, and protecting the operator from being harmed by high-speed moving parts.
[0046] In addition, a bearing seat 14 is disposed on the upper surface of the base 1 . The bearing seat 14 is located at one side of the through opening 62 . The bearing seat 14 is used to bear the straw, so that the operator can take the straw easily.
[0047] The implementation principle of the desktop straw machine in the embodiment of the present application is: First, the stacked paper stored in the storage box 2 is sent to the forming mold 4 through the discharge port 22. In the forming mold 4, the outer cylinder 42 is sleeved on the outside of the inner cylinder 41 to form a forming groove 411, and the caliber of the groove is designed to gradually decrease from one end of the storage box 2 to the other end to adapt to the size change during the straw forming. The hot pressing assembly 43, including a driving motor 431, a hot pressing roller 432 and a driven roller 433, is used to press the overlapping areas on both sides of the paper and utilize the temperature and pressure of the hot pressing roller 432 to make the paper bond and form into a straw. The formed straw is pushed by the push plate set at the end of the piston rod of the push cylinder 3, pushed out of the forming groove 411, and the push plate is movably inserted into the storage box 2 and passes through the discharge port 22 to push the formed straw to the specified position. The whole process realizes the continuous automatic production from paper to straw, which not only saves space, but also improves production efficiency and convenience.
[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
