Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of bamboo toothbrush forming methods, specifically relating to a continuous forming device and method for bamboo toothbrushes. Background Technology
[0002] Bamboo toothbrushes are made from bamboo. They are characterized by their toughness, wear resistance, softness, and smoothness.
[0003] The process of making bamboo toothbrush handles from bamboo strips involves numerous steps and is inefficient. A search reveals that the existing automatic milling machine for round-handled bamboo toothbrushes, disclosed in patent CN 213165863 U, uses a three-axis structure, processing only one product at a time. It employs front loading and unloading, which cannot be done simultaneously. The head uses a pneumatic finger gripping method or a buffer-back-support method; the pneumatic fingers must be released after one side is processed before the other side can be clamped and processed. This clamping structure is inefficient, processing only about 120 toothbrushes per hour, and the clamping force is insufficient, leading to workpiece displacement and large tolerances (up to 0.4mm). Because the toothbrush head is asymmetrical, clamping the top and bottom surfaces while processing the sides causes vertical displacement. The three-axis structure cannot simultaneously chamfer the top and bottom edges when milling the sides, requiring secondary chamfering.
[0004] Patent CN102441930A discloses a method for manufacturing a bamboo toothbrush handle and its forming grinding machine device. The forming steps of the handle are as follows: using a grinding machine equipped with different grinding wheels to process each axial surface of the bamboo segment to obtain a brush handle blank. The main problem is that the operation steps are relatively cumbersome, requiring grinding each axial surface of the brush handle, involving multiple grinding wheels and cutting tools, resulting in insufficient stability and low processing efficiency during the processing.
[0005] The main problems currently existing in the processing of bamboo toothbrush handles are the design of milling fixtures, low processing efficiency, and large product variability.
[0006] Based on this, a continuous forming equipment and method for bamboo toothbrushes is proposed. By directly processing 2m long bamboo strips, 10 bamboo toothbrushes can be milled at one time, improving processing efficiency and ensuring processing homogeneity. Summary of the Invention
[0007] The technical problem to be solved by the present invention is to provide a continuous forming device and method for bamboo toothbrushes to address the shortcomings of the prior art mentioned above.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0009] In a first aspect, a continuous forming device for bamboo toothbrushes includes a main frame and an auxiliary frame, wherein the auxiliary frame is bolted into the main frame and a toothbrush collecting groove is installed in the auxiliary frame;
[0010] A clamp slide is slidably connected to the top surface of the main frame. A rack is provided inside the main frame near the top. A drive gear is connected to the clamp slide through a servo motor. The drive gear and the rack are meshed together.
[0011] The bottom surface of the clamp slide is movably connected to a clamping plate by two transverse cylinders that are symmetrically fixed to the bottom surface of the clamp slide. The clamping plate is used to perform clamping operations on the ends of the raw bamboo material.
[0012] A feeding rack is provided at the feed inlet of the main frame, and a milling cutter support plate is provided inside the main frame near the feeding rack. A milling cutter motor is slidably connected to the milling cutter support plate near the feeding rack, and a milling arc cutter is installed on the milling cutter motor.
[0013] A dividing support frame is vertically slidably connected to the middle of the top surface of the auxiliary frame via a lifting cylinder. Ten dividing cavities are installed at equal intervals on the dividing support frame. Each dividing cavity has a hollow cavity in the middle. A support plate is rotatably connected to the top opening of each dividing cavity. An arc-shaped dividing blade is rotatably connected to the other end of the top surface of the dividing cavity opposite to the pivot of the support plate. The other end of the arc-shaped dividing blade is slidably connected to the support plate.
[0014] Furthermore, the fixture slide is equipped with two transverse roller groups and two longitudinal roller groups. Each roller group consists of two symmetrical rollers. The lateral sliding connection of the fixture slide on the main frame is completed by the cooperation of the four roller groups.
[0015] Furthermore, the clamping center line of the clamping plate and the feeding center line of the feeding rack are on the same straight line.
[0016] Furthermore, two transversely arranged milling cutter cylinders are symmetrically installed inside the milling cutter support plate, and the milling cutter motor is installed at the end of the telescopic shaft of the milling cutter cylinder.
[0017] Furthermore, a miniature hydraulic rod is rotatably connected inside the hollow cavity of the segmented cavity, and the top end of the miniature hydraulic rod is rotatably connected to the inner bottom surface of the support plate.
[0018] Furthermore, a limiting groove is formed on the top surface of the support plate, and a limiting ball is fixed at the other end of the arc-shaped dividing blade, with the limiting ball slidably connected within the limiting groove.
[0019] Furthermore, when the support plate is in the open state, the lower end of the support plate faces the material collection port of the toothbrush collection groove.
[0020] Secondly, a continuous forming method for a bamboo toothbrush includes the following steps:
[0021] S1. First, use the servo motor to drive the active gear to rotate the clamp slide to move to the feeding rack. Then open the clamp plate and pass the bamboo strip raw material with a size of 2000×13×7mm through the feeding rack, and clamp the end of the bamboo strip in the clamp plate.
[0022] S2. Then, the servo motor drives the active gear to rotate the fixture slide to move the distance of a single bamboo toothbrush handle, and then the servo motor stops.
[0023] S3. Use the milling cutter cylinder to push the milling cutter motor close to the processing area of the bamboo strip, and then use the milling cutter motor to drive the milling arc cutter to rotate and process. After a single processing is completed, use the milling cutter cylinder to pull the milling cutter motor away to complete the single processing of the bamboo toothbrush handle.
[0024] S4. Repeat S2-S3 until the processing of ten bamboo toothbrush handles is completed. After processing, use a servo motor to adjust the position of the bamboo strips so that the dividing position of the ten bamboo toothbrush handles is aligned with the position of the arc-shaped dividing blade on the dividing support frame.
[0025] S5. Then, use the lifting cylinder to vertically raise the dividing support frame until the top surface of the dividing lifting frame touches the bottom surface of the processed bamboo strip.
[0026] S6. Using a miniature hydraulic rod to open and drive the support plate to rotate upward, the support plate rotates upward and drives the arc-shaped dividing blade to move upward, completing the division of the bamboo toothbrush handle, and completing the division of ten bamboo toothbrush handles.
[0027] S7. After the bamboo toothbrush handle is split, it slides down the support plate and falls into the toothbrush collection slot to complete the collection, thus completing the processing of a single bamboo strip.
[0028] Furthermore, a feed roller is rotatably connected inside the feed rack.
[0029] Furthermore, the length of the main frame is greater than the length of the auxiliary frame.
[0030] Compared with the prior art, the present invention has the following advantages:
[0031] 1. The present invention installs an auxiliary frame inside the main frame with bolts. A toothbrush collecting groove is installed inside the auxiliary frame. A clamping slide is slidably connected to the top surface of the main frame. A rack is provided inside the main frame near the top. A clamping plate is movably connected to the bottom surface of the clamping slide through two transverse cylinders that are symmetrically fixed to the bottom surface of the clamping slide. The clamping plate is used to complete the clamping operation of the end of the raw bamboo material.
[0032] 2. This invention symmetrically installs two transversely arranged milling cutter cylinders inside the milling cutter support plate. The milling cutter motor is installed at the end of the telescopic shaft of the milling cutter cylinder, and a milling arc cutter is installed on the milling cutter motor. The milling arc cutter can be used to process bamboo strips.
[0033] 3. In this invention, a segmentation support frame is vertically slidably connected to the middle of the top surface of the auxiliary frame via a lifting cylinder. Ten segmentation cavities are installed at equal intervals on the segmentation support frame. A hollow cavity is opened in the middle of each segmentation cavity. A support plate is rotatably connected to the top opening of each segmentation cavity. An arc-shaped segmenting blade is rotatably connected to the other end of the top surface of the segmentation cavity opposite to the pivot of the support plate. The other end of the arc-shaped segmenting blade is slidably connected to the support plate. A miniature hydraulic rod is rotatably connected inside the hollow cavity of the segmentation cavity. The top end of the miniature hydraulic rod is rotatably connected to the inner bottom surface of the support plate.
[0034] In practice, the process begins by using a servo motor to drive the drive gear, rotating the fixture slide to the feeding rack. Then, the clamping plate is opened, allowing the bamboo strip to pass through the feeding rack, and the end of the bamboo strip is secured within the clamping plate. Next, the servo motor drives the drive gear again, rotating the fixture slide a single distance for the bamboo toothbrush handle. The servo motor is then stopped, and a milling cutter cylinder pushes the milling cutter motor closer to the processing area of the bamboo strip. The milling cutter motor then drives the milling cutter to rotate and process the bamboo strip. After each processing cycle, the milling cutter cylinder pulls the milling cutter motor away, completing the single processing of the bamboo toothbrush handle. This process is repeated until ten bamboo toothbrush handles are processed. After processing, the position of the bamboo strip is adjusted using a servo motor until the dividing positions of the ten bamboo toothbrush handles are aligned with the position of the arc-shaped dividing blade on the dividing support frame. Then, the dividing support frame is vertically raised using a lifting cylinder until the top surface of the dividing lifting frame rests against the bottom surface of the processed bamboo strip. A micro hydraulic rod is used to open and drive the support plate to rotate upward. During the upward rotation of the support plate, the arc-shaped dividing blade moves upward, completing the dividing position of the bamboo toothbrush handles. After the bamboo toothbrush handles are divided, they slide down along the support plate and fall into the toothbrush collection slot for collection, thus completing the processing of a single bamboo strip.
