Description

Technical Field

[0001] This utility model relates to the technical field of plastic rattan processing equipment, and in particular to a plastic rattan fixed-length cutting device. Background Technology

[0002] In the plastics manufacturing and processing industry, plastic rattan is a common product widely used in furniture making, garden decoration, handicrafts, and many other fields. With the continuous growth and diversification of market demand, higher requirements are being placed on the processing precision and production efficiency of plastic rattan. Traditional methods of cutting plastic rattan often rely on manual operation, with workers using simple cutting tools (such as knives and scissors) to manually measure and cut the rattan based on experience. This method has many drawbacks:

[0003] (a) Low work efficiency

[0004] Manual measurement and cutting are slow, especially in mass production, which cannot meet the demand for efficient production, leading to longer production cycles and increased production costs.

[0005] Workers need to work continuously for long periods of time, which can easily lead to fatigue, further affecting work efficiency and the stability of cutting quality.

[0006] (ii) Poor cutting accuracy

[0007] Human measurement inevitably introduces certain errors, making it difficult to guarantee consistent dimensional accuracy at each cutting point, resulting in inconsistent product quality.

[0008] The lack of precise positioning and guiding devices makes the cutter prone to deviation during the cutting process, resulting in an uneven cut surface that affects the product's appearance and performance.

[0009] (III) Security Issues

[0010] When workers use cutting tools, they are prone to accidental injuries, such as cutting their fingers, due to improper operation or lack of concentration.

[0011] Some cutting tools may generate spatter during operation, posing a threat to the surrounding environment and the safety of operators.

[0012] (iv) Waste of resources

[0013] Because the cutting precision cannot be guaranteed, some plastic rattan may be discarded due to non-compliance with size requirements, resulting in a waste of raw materials.

[0014] Improper cutting operations may also damage the vines, reduce their utilization rate, and further waste resources.

[0015] In order to overcome the shortcomings of traditional plastic rattan cutting methods, improve production efficiency, cutting accuracy and product quality, and at the same time ensure the safety of operators and reduce resource waste, there is an urgent need to develop a plastic rattan fixed-length cutting device with a high degree of automation, high precision and safety.

[0016] Chinese patent discloses a plastic pipe cutting machine (publication number: CN 213765997 U). The support frame is an inverted U-shaped structure, vertically fixed on the main frame. The positioning frame is divided into a horizontal frame and a vertical frame. The front end of the horizontal frame is equipped with a feeding bucket, and the rear end is fixed with a positioning baffle and supported by the vertical frame. The downward push cylinder, cutting cylinder, blade and mold of the cutting mechanism are located in the support frame. The downward push cylinder is located above the baffle. However, this plastic pipe cutting machine has low working efficiency and poor cutting accuracy. Human measurement inevitably has a certain error, making it difficult to ensure that the dimensional accuracy of each cutting point is consistent, resulting in inconsistent product quality. The lack of precise positioning and guiding devices makes the cutter prone to deviation during the cutting process, resulting in an uneven cut surface, affecting the appearance and performance of the product. Therefore, a plastic rattan fixed length cutting device is needed. Utility Model Content

[0017] The purpose of this utility model is to solve the shortcomings of existing plastic pipe cutting machines, such as low working efficiency, poor cutting accuracy, inevitable errors in human measurement, difficulty in ensuring consistent dimensional accuracy at each cutting point, resulting in inconsistent product quality, and lack of precise positioning and guiding devices, which makes the cutter prone to deviation during the cutting process, resulting in uneven cut surfaces and affecting the appearance and performance of the product. Therefore, a plastic rattan fixed-length cutting device is proposed.

[0018] The technical solution adopted by this utility model to solve its technical problem is as follows: A plastic rattan fixed-length cutting device, comprising a base, characterized in that: a mounting frame is provided on the base, the mounting frame is composed of a mounting plate and several connecting rods, a cutting component is provided on the mounting frame, a conveying component is provided on one side of the cutting component, a laser positioning component is provided on one side of the conveying component, and a collection frame is provided on the other side. By setting the mounting frame composed of the mounting plate and connecting rods on the base, the structure of the entire device is more stable and robust, the installation position of each component is relatively accurate and reliable, which is beneficial to improving the overall stability and operating accuracy of the device, and reducing errors and malfunctions caused by structural instability; the coordinated use of the cutting component, the conveying component, and the laser positioning component realizes the automated fixed-length cutting process of plastic rattan. The conveying component can continuously and stably transport the rattan to the designated position, the laser positioning component can accurately measure and determine the cutting point, and the cutting component performs accurate cutting operations according to the settings, which greatly improves the efficiency and accuracy of cutting and reduces the errors and inconsistencies that may be caused by manual operation. The collection box effectively solves the problem of storing the cut rattan, preventing the rattan from scattering everywhere. This not only makes the working environment cleaner and more orderly, but also facilitates the subsequent unified collection, sorting and transfer of the cut rattan, improving work efficiency and the convenience of production management.

[0019] Preferably, the cutting assembly includes a drive motor, one end of which is connected to a motor shaft, the other end of which is connected to a transmission shaft, and the other end of which is connected to a main transmission gear. A secondary transmission gear is located below the main transmission gear, and a transmission belt is shared by both the main and secondary transmission gears. Using a drive motor as the power source provides a stable and adjustable power output, capable of adapting to the cutting needs of plastic rattan of different thicknesses and materials. By controlling parameters such as the motor's speed and torque, the cutting speed and force can be flexibly adjusted, ensuring the stability and reliability of the cutting process. The transmission system composed of the motor shaft, transmission shaft, main and secondary transmission gears, and transmission belt forms a multi-stage transmission structure.

[0020] Preferably, one end of the main drive gear passes through the mounting plate and is connected to a drive wheel. One end of the drive wheel is provided with a connecting rod, one end of the connecting rod is provided with a drive rod, and one end of the drive rod is provided with a connecting block. A cutter is located at the bottom of the connecting block, and a first linear slide rail is provided on one side of the connecting block. The first linear slide rail is associated with the mounting plate. The main drive gear transmits power to the cutter through a series of components such as the drive wheel, connecting rod, and drive rod. This transmission method converts rotational motion into linear reciprocating motion of the cutter, achieving effective cutting of the plastic rattan. Moreover, through reasonable design and layout, the movement amplitude and speed of the cutter can be adjusted according to actual needs to adapt to the cutting requirements of rattan of different diameters and materials. The association design between the first linear slide rail and the mounting plate provides precise motion guidance for the connecting block and the cutter. During the movement of the cutter along the linear slide rail, it can always maintain a perpendicular cutting angle with the plastic rattan, resulting in a smoother and flatter cut surface, improving cutting quality and product appearance. Simultaneously, the linear motion also helps reduce cutter wobbling and deviation during the cutting process, improving cutting stability and accuracy, and reducing the scrap rate.

[0021] Preferably, one end of the secondary transmission gear passes through the mounting plate and is connected to a roller. There are two rollers, arranged vertically and correspondingly. A track frame is provided between the rollers, and a track groove is provided on the track frame. A conveyor belt is provided on one side of the track frame. The cooperation between the rollers and the track groove significantly improves the stability and accuracy of the movement of the secondary transmission gear and related components. The rolling of the rollers within the track groove effectively limits the radial and axial displacement of the components, reducing swaying and vibration, making the entire transmission system more stable and reliable during operation. The conveyor belt, working in conjunction with the rollers and other components, achieves stable transport and accurate positioning of the plastic rattan.

[0022] Preferably, the roller is coated with a polyurethane coating. The application of the polyurethane coating significantly improves the roller's wear resistance and service life. During prolonged use, the roller needs to roll frequently and come into contact with other components. Ordinary roller surfaces are prone to wear, leading to dimensional changes and increased surface roughness, affecting the normal operation of the device. The polyurethane coating effectively resists these wear factors, maintaining the flatness and dimensional accuracy of the roller surface, ensuring stable and efficient operation. Due to the polyurethane coating's excellent coefficient of friction and grip, the roller can better cooperate with the track or other contact surfaces during rotation, reducing slippage and ensuring the accuracy and stability of power transmission. This not only helps improve the overall working efficiency of the device but also reduces abnormal friction and heat generation between components caused by slippage, lowering the equipment's failure rate and maintenance costs.

[0023] Preferably, the laser positioning component includes a support block, a second linear slide rail at the top center of the support block, a sliding block on the second linear slide rail, and a laser rangefinder above the sliding block. The structural system consisting of the support block, the second linear slide rail, and the sliding block provides the laser rangefinder with highly precise position adjustment capabilities. In actual operation, depending on the specifications and shapes of the plastic rattan and the cutting requirements, the laser rangefinder can be quickly and accurately adjusted to a suitable measurement position by moving the sliding block on the second linear slide rail, ensuring that the laser beam can perpendicularly irradiate the part of the rattan to be cut, thereby achieving high-precision positioning measurement.

[0024] The advantages of this utility model are:

[0025] This application achieves automated conveying, positioning, and cutting of plastic rattan by coordinating the operation of a motor-driven conveyor belt, main drive gear, and auxiliary drive gear. This significantly reduces manual intervention and improves production efficiency. Compared to traditional manual cutting methods, it can complete the cutting of a large number of plastic rattan strips in a short time, effectively shortening the production cycle. The laser positioning system is precise and reliable. The laser rangefinder can accurately measure the length of the plastic rattan strips in real time and transmit the measurement data to the control system. The control system precisely controls the action of the cutting components according to the set cutting length, ensuring that the dimensional accuracy of each cutting point reaches a high level, effectively avoiding dimensional inconsistencies caused by human measurement errors. Due to the use of precise laser positioning and a stable mechanical transmission structure, the device can ensure that the cutting length and cut surface quality of each plastic rattan strip are basically consistent, greatly improving the stability of product quality. This is of great significance for subsequent production, processing, and use, reducing problems such as increased defect rates and customer complaints caused by unstable product quality. Safety devices such as safety guards and safety railings are provided to effectively prevent operators from accidentally coming into contact with moving parts during equipment operation, reducing the risk of safety accidents.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] Example

[0033] Please see Figure 1-3 As shown, a plastic rattan fixed-length cutting device includes a base 8. The base 8 is characterized by a mounting frame 16, which is composed of a mounting plate 2 and several connecting rods 3. A cutting assembly is mounted on the mounting frame 16, a conveying assembly is located on one side of the cutting assembly, a laser positioning assembly is located on one side of the conveying assembly, and a collection frame 9 is located on the other side. By setting the mounting frame 16, composed of the mounting plate 2 and connecting rods 3, on the base 8, the entire device structure is more stable and robust, and the installation positions of each component are relatively accurate and reliable. This improves the overall stability and operational accuracy of the device, reducing errors and malfunctions caused by structural instability. The coordinated use of the cutting assembly, conveying assembly, and laser positioning assembly enables an automated fixed-length cutting process for the plastic rattan. The conveying component can continuously and stably transport the rattan to the designated position, the laser positioning component can accurately measure and determine the cutting point, and the cutting component performs accurate cutting operations according to the settings, which greatly improves the efficiency and accuracy of cutting and reduces the errors and inconsistencies that may be caused by manual operation. The collection box 9 effectively solves the problem of storing the cut rattan, preventing the rattan from scattering everywhere. This not only makes the working environment more tidy and orderly, but also facilitates the subsequent unified collection, sorting and transfer of the cut rattan, improving work efficiency and the convenience of production management.

[0034] In this embodiment, the cutting assembly includes a drive motor 1, one end of which is connected to a motor shaft 19, and the other end of which is connected to a transmission shaft 18. A main transmission gear 17 is connected to one end of the transmission shaft 18, and a secondary transmission gear 21 is located below the main transmission gear 17. A transmission belt 20 is shared by the main transmission gear 17 and the secondary transmission gear 21. Using the drive motor 1 as a power source provides stable and adjustable power output, adapting to the cutting needs of plastic rattan of different thicknesses and materials. By controlling parameters such as the motor's speed and torque, the cutting speed and force can be flexibly adjusted, ensuring the stability and reliability of the cutting process. The transmission system composed of the motor shaft 19, the transmission shaft 18, the main and secondary transmission gears 21, and the transmission belt 20 forms a multi-stage transmission structure.

[0035] In this embodiment, one end of the main drive gear 17 passes through the mounting plate 2 and is connected to a drive wheel 4. One end of the drive wheel 4 is provided with a connecting rod 5, and one end of the connecting rod 5 is provided with a drive rod 6. One end of the drive rod 6 is provided with a connecting block 14. A cutter 7 is located at the bottom of the connecting block 14, and a first linear slide rail 15 is provided on one side of the connecting block 14. The first linear slide rail 15 is associated with the mounting plate 2. The main drive gear 17 transmits power to the cutter 7 through a series of components such as the drive wheel 4, connecting rod 5, and drive rod 6. This transmission method can convert rotational motion into linear reciprocating motion of the cutter 7, achieving effective cutting of plastic rattan. Moreover, through reasonable design and layout, the movement amplitude and speed of the cutter 7 can be adjusted according to actual needs to adapt to the cutting requirements of rattan of different diameters and materials. The associated design of the first linear slide rail 15 with the mounting plate 2 provides precise motion guidance for the connecting block 14 and the cutter 7. As the cutter 7 moves along the linear guide rail, it maintains a perpendicular cutting angle to the plastic rattan, resulting in a smoother, flatter cut surface and improved cutting quality and product appearance. Simultaneously, the linear motion helps reduce wobble and deviation of the cutter 7 during the cutting process, enhancing cutting stability and precision, and lowering the scrap rate.

[0036] In this embodiment, one end of the secondary transmission gear 21 passes through the mounting plate 2 and is connected to a roller 12. There are two rollers 12 arranged vertically, with a track frame 10 between them. The track frame 10 has a track groove 11, and a conveyor belt 25 is provided on one side of the track frame 10. The cooperation between the rollers 12 and the track groove 11 significantly improves the stability and accuracy of the movement of the secondary transmission gear 21 and related components. The rolling of the rollers 12 within the track groove 11 effectively limits the radial and axial displacement of the components, reducing swaying and vibration, making the entire transmission system more stable and reliable during operation. The conveyor belt 25, working in conjunction with the rollers 12 and other components, achieves stable transport and accurate positioning of the plastic rattan.

[0037] In this embodiment, the roller 12 is provided with a polyurethane coating 13. The application of the polyurethane coating 13 greatly improves the wear resistance and service life of the roller 12. During long-term use, the roller 12 needs to roll frequently and come into contact with other components. Ordinary roller 12 surfaces are prone to problems such as dimensional changes and increased surface roughness due to wear, affecting the normal operation of the device. The polyurethane coating 13 can effectively resist these wear factors, maintain the flatness and dimensional accuracy of the roller 12 surface, and ensure that the roller 12 can always work stably and efficiently. Because the polyurethane coating 13 has a good coefficient of friction and grip, the roller 12 can better cooperate with the track or other contact surfaces during rotation, reducing slippage and ensuring the accuracy and stability of power transmission. This not only helps to improve the overall working efficiency of the device, but also reduces abnormal friction and heat generation between components caused by slippage, reducing the failure rate and maintenance costs of the equipment.

[0038] In this embodiment, the laser positioning component includes a support block. A second linear slide rail 24 is located at the top center of the support block. A sliding block 23 is mounted on the second linear slide rail 24, and a laser rangefinder 22 is positioned above the sliding block 23. The structural system consisting of the support block, the second linear slide rail 24, and the sliding block 23 provides the laser rangefinder 22 with highly precise position adjustment capabilities. In actual operation, depending on the specifications and shapes of the plastic rattan and the cutting requirements, the laser rangefinder 22 can be quickly and accurately adjusted to a suitable measurement position by moving the sliding block 23 on the second linear slide rail 24, ensuring that the laser beam can perpendicularly irradiate the part of the rattan to be cut, thereby achieving high-precision positioning measurement.

[0039] The implementation principle of this embodiment is as follows:

[0040] (I) Preparation Stage

[0041] Place the plastic rattan length-cutting device in a suitable work area, ensuring it is installed stably and securely, and properly connected to a power supply source. Adjust the cutting assembly (including main drive gear 17, secondary drive gear 21, connecting rod 5, transmission rod 6, connecting block 14, and cutter 7) to a suitable initial position via the first linear slide rail 15, so that the cutter 7 is ready to cut. Adjust the position of the laser positioning assembly (including laser rangefinder 22 and laser light) via the second linear slide rail 24 on the support block according to the required specifications and length of the plastic rattan to be cut, so that it can accurately measure the position on the rattan that needs to be cut.

[0042] (II) Transportation Stage

[0043] The plastic rattan is placed on the conveyor belt 25, and the drive motor 1 of the conveyor belt 25 is turned on, causing the conveyor belt 25 to rotate at a constant speed. Driven by the conveyor belt 25, the plastic rattan is stably conveyed towards the cutting assembly. During the conveying process, the speed of the conveyor belt 25 can be adjusted according to actual production needs to ensure it matches the working rhythm of the cutting assembly. When the plastic rattan is conveyed close to the cutting position, the laser positioning assembly begins to perform real-time positioning measurement of the rattan. The laser rangefinder 22 emits a laser beam, illuminating the surface of the plastic rattan, and transmits the measurement data to the control system.

[0044] (III) Cut-off stage

[0045] The control system determines whether the plastic rattan has reached the set cutting length based on data measured by the laser rangefinder 22. When the set length is reached, the control system immediately issues a command to stop the drive motor 1, causing the transmission belt 20 to stop conveying the plastic rattan. Simultaneously, the main drive gear 17 starts rotating under the drive of the motor, transmitting power to the connecting rod 5 through a series of transmission components such as the drive shaft 18, universal joint, and drive rod 6. The connecting rod 5 drives the connecting block 14 to move linearly along the first linear slide rail 15, thereby moving the cutter 7 downward to cut the plastic rattan. During the cutting process, the secondary drive gear 21 also rotates synchronously under the drive of the motor, cooperating with the track groove 11 on the track frame 10 through the roller 12 to ensure the stability and accuracy of the entire cutting process. After cutting, the control system issues another command to perform the next cutting operation. This cycle repeats continuously to achieve continuous fixed-length cutting of the plastic rattan.

[0046] (iv) Collection Phase

[0047] The cut plastic rattan falls into the collection box 9 under the influence of gravity. The collection box 9 is located at the bottom of the device for easy collection and sorting of the cut rattan.
