Technical Field

[0001] The utility model belongs to the technical field of material sorting, and in particular relates to a glass block transmission mechanism and a sorting weighing machine. Background Art

[0002] The utility model is based on the prior application of publication number CN103272781A, an automatic sorting and weighing machine and the technical basis of the working process. The above equipment conveying device adopts a direct vibration type, which relies entirely on the centrifugal force of the product for sorting. The original structure adopts a V-shaped guide groove and uses a linear vibrator to feed the material forward. In the process of sorting and weighing the glass blocks, there are the following problems:

[0004] (2) The direct vibration stop has braking and inertia time, which will cause a large error in the weight of the glass, which is not conducive to the accuracy of sorting.

[0005] (3) The direct vibration type will cause the glass products to overlap during the movement, thus affecting the quantity statistics of the sorting. Utility Model Content

[0022] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0023] Example 1

[0024] This embodiment provides a glass block transmission mechanism. Figure 1 , 2 , including: a transmission mechanism, the transmission mechanism includes a driving wheel 1, a driven wheel 2 and a transmission belt 3, the driving wheel 1 is connected to a servo motor, the servo motor drives the driving wheel 1 to rotate, and drives the transmission belt 3 to run. The precise control ability of the servo motor enables the transmission belt 3 to start and stop stably, ensuring the stability of the material transmission process.

[0025] The feeding end of the transmission belt 3 is provided with a blocking mechanism 4 and a first photoelectric switch 5. The first photoelectric switch 5 is located at the feeding end of the transmission belt 3 and is used to detect the feeding situation. Its laser generating end 14 and receiving end are installed on baffles 11 on both sides of the transmission belt 3. When the material passes, the laser beam is blocked, the photoelectric switch senses the presence of the material, and the signal is fed back to the controller. The blocking mechanism 4 is composed of baffle 2 and a cylinder arranged in a vertical manner. The cylinder is installed at the top of the feeding channel, and baffle 2 is connected to the output end of the cylinder. When the first photoelectric switch 5 detects that the feeding speed is too fast, the controller controls the cylinder to move, move baffle 2 downward, temporarily close the feeding channel, and prevent material accumulation.

[0026] The discharging end of the transmission belt 3 is provided with a second photoelectric switch 6, which is located at the discharging end of the transmission belt 3 and is used to monitor the discharging of materials. Its working principle is similar to that of the first photoelectric switch 5, and it sends a signal to the controller by sensing the passing of materials.

[0027] The first photoelectric switch 5 , the second photoelectric switch 6 and the servo motor are all electrically connected to the controller.

[0028] By implementing the above technical solution, the following technical effects can be achieved:

[0029] Reduce the breakage rate: adopt high-performance anti-skid transmission belt 3, the transmission process is smooth, and the breakage of glass blocks caused by collision and extrusion in the vibration extrusion method is avoided.

[0030] Improve transmission efficiency and stability: The precise control of the servo motor enables the transmission belt 3 to start and stop stably, reduces the error caused by inertia, and improves the stability of the transmission process.

[0031] Achieve precise control and monitoring: The photoelectric switch monitors the material in and out in real time and feeds the data back to the controller. The controller adjusts the speed of the servo motor based on the feedback to ensure that the material enters the next process at an appropriate speed and frequency.

[0032] Prevent material accumulation and overlap: The blocking mechanism 4 closes the feeding channel in time when there is too much material to prevent material accumulation and ensure smooth transmission. In addition, through reasonable control, ensure that the material enters the weighing device 8 in an orderly manner to avoid overlap and ensure the accuracy of weighing and sorting.

[0033] In this embodiment, the transmission belt 3 is arranged horizontally, the feeding end is connected to a container 7, and the discharging end is connected to a weighing device 8. When in use, materials are added to the container 7, and the materials in the container 7 enter the conveying device along the conveying channel, and the transmission speed and frequency of the materials are controlled by the transmission belt 3, and the materials enter the weighing device 8 one by one for weighing.

[0034] In this embodiment, a rectangular feeding channel is provided above the transmission belt 3, and the rectangular feeding channel is composed of two baffles 11 on both sides of the transmission belt 3, and the baffles 11 are parallel to the length direction of the transmission belt 3. These baffles 11 ensure that the material remains within the predetermined path during the transmission process to avoid lateral movement or falling.

[0035] The installation method is that the baffle 11 is fixed on both sides of the transmission belt 3 to ensure that the distance and height with the transmission belt 3 are consistent, so that the material can smoothly pass through the rectangular feeding channel. The height and width of the baffle 11 are reasonably designed to adapt to the size of the glass block to ensure that the glass block will not get stuck or tilted during the transmission process.

[0036] Description of the function of the baffle 11: The main function of the baffle 11 is to guide and ensure that the glass block moves along the center line of the transmission belt 3 to avoid lateral deviation, so as to ensure that the material can accurately enter the subsequent weighing and sorting device 9. The baffle 11 plays a protective role in the transmission process, preventing the glass block from being damaged due to lateral collision, and also preventing external interference from entering the transmission path.

[0037] In this embodiment, the first photoelectric switch 5 includes a laser generating end 14 and a laser receiving end 15. The laser generating end 14 is mounted on the left side baffle 11 of the transmission belt 3, and emits a stable and continuous laser beam. The laser receiving end 15 is mounted on the right side baffle 11 of the transmission belt 3, opposite to the laser generating end 14, and receives the laser beam.

[0038] Working principle: The laser generating end 14 continuously emits a laser beam, and the laser receiving end 15 continuously receives the laser beam. When the glass block passes the photoelectric switch position on the transmission belt 3, the laser beam is temporarily blocked. The laser receiving end 15 detects the interruption of the laser beam and transmits this signal to the controller. The controller can determine the passing condition of the material by the number and frequency of the laser beam interruption.

[0039] In this embodiment, the blocking mechanism 4 includes a baffle plate 2 and a cylinder. The baffle plate 2 is arranged vertically and has a rectangular shape that matches the rectangular feeding channel, ensuring that the feeding channel can be completely covered to effectively block the material. The cylinder is installed at the top of the feeding channel to drive the baffle plate 2 to move up and down. The cylinder is connected to the upper part of the feeding channel and is connected to the baffle plate 2 through its output end.

[0040] Working principle:

[0041] Baffle 2 movement control: The cylinder drives baffle 2 to move up and down in the feeding channel by controlling the telescopic action of its output end. The specific operation is as follows:

[0042] Closing the feeding channel: When it is necessary to prevent the material from continuing to enter the transmission belt 3, the controller sends a signal to the cylinder. After receiving the signal, the output end of the cylinder extends downward, pushing the baffle plate 2 to move downward until the baffle plate 2 completely closes the rectangular feeding channel. By closing the feeding channel in time, excessive material is prevented from entering the transmission belt 3, avoiding accumulation and blockage, and improving the stability of the transmission system.

[0043] Open the feeding channel: When the feeding needs to be resumed, the controller sends a signal to the cylinder. After receiving the signal, the output end of the cylinder contracts upward, pushing the baffle plate 2 to move upward until the baffle plate 2 completely opens the rectangular feeding channel, allowing the material to continue to enter the transmission belt 3.

[0044] By precisely controlling the opening and closing of the baffle plate 2, the material feeding speed can be precisely adjusted, which effectively prevents material accumulation, improves the stability and safety of the feeding process, and ensures the continuity and reliability of the glass block transmission process.

[0045] In this embodiment, the second photoelectric switch 6 includes a photoelectric detection device arranged at the top of the rectangular feeding channel and a sensing paddle 12 inside the rectangular feeding channel. The sensing paddle 12 is installed between the baffles 11 by rotating the shaft. The second photoelectric device is used to sense the position of the sensing paddle 12. When the material passes through the rectangular feeding channel, it will hit the sensing paddle 12, pushing it to rotate around the shaft. The sensing paddle 12 moves under the action of the material and returns to the initial position. The position change of the sensing paddle 12 will be captured by the photoelectric detection device. The photoelectric detection device determines whether the position of the sensing paddle 12 changes by detecting the change of the reflected light signal, thereby determining whether there is material passing through, and determining the amount of material on the material bag according to the length of the gap time when the material passes through. Feedback is given to the controller. Through the combination of the induction paddle 12 and the photoelectric detection device, the system can accurately detect the passage of materials and provide real-time feeding speed and gap time data. Through feedback control, the controller can automatically adjust the speed of the servo motor according to the real-time detection data to ensure that the material enters the weighing device 8 at an appropriate speed, avoid multiple materials entering the weighing device 8 at the same time, ensure the order of transportation of the discharged materials, form a chain state, and enter the weighing device 8 one by one for weighing, thereby ensuring the accuracy of weighing and avoiding the trouble of multiple materials entering the weighing device 8 at the same time.

[0046] In a further embodiment, the photoelectric detection device includes a laser generating end 14 and a laser receiving end 15 which are oppositely arranged on the baffle 11. The laser generating end 14 is arranged on one side of the baffle 11 for emitting a laser beam. The laser receiving end 15 is arranged on the other side of the baffle 11, opposite to the laser generating end 14, for receiving a laser beam. The sensing paddle 12 is installed inside the rectangular feeding channel and is connected between the baffles 11 through a rotating shaft, and its upper end is located on the laser beam path. When the sensing paddle 12 is stationary, the laser receiving end 15 cannot receive the laser signal. When the sensing paddle 12 moves, the sensing paddle 12 contacts the laser and the laser receiving end 15 receives the laser sensing signal. By detecting the gap time, the material speed can be calculated.

[0047] Example 2

[0048] A sorting and weighing machine, see Figure 3, including a base 13, a container 7 arranged above the base 13 and fixedly connected thereto, and the above-mentioned glass block transmission mechanism connected to the container 7 and arranged on the base 13, and a weighing device 8 connected to the glass block transmission mechanism and arranged on the base 13, and a sorting device 9 connected to the weighing device 8, and a material receiving device 10 connected to the sorting device 9. Among them, the base 13 serves as a supporting platform for the entire device and has sufficient stability and load-bearing capacity. The container 7 is installed above the base 13 and is used to store and preliminarily distribute materials. The container 7 is connected to the conveying device to ensure that the materials can smoothly enter the conveying channel. The conveying device includes a transmission mechanism, a driving wheel 1, a driven wheel 2, a transmission belt 3, a blocking mechanism 4, a photoelectric switch and other components, which are used to control the transmission speed and frequency of the materials. The weighing device 8 is installed on the base 13 and connected to the conveying device, and is used to accurately weigh the incoming materials. The sorting device 9 is connected to the weighing device 8, and is used to classify and distribute the materials according to the weighing results. The material receiving device 10 is connected to the sorting device 9 and is used for receiving and collecting the sorted materials.

[0049] After the power is turned on, the entire weighing machine system is started through the controller. The controller will first activate the container 7 and start feeding the conveying device. The weighing machine is turned on through the controller, and the material enters the conveying channel from the container 7. The transmission belt 3 starts working. The transmission speed is adjusted by the controller to ensure that the material is transmitted at the set frequency and speed. During the material transmission process, the photoelectric switch monitors the passage of the material in real time, feeds back the signal to the controller, adjusts the transmission speed, and ensures that the material enters the weighing device 8 one by one. After the material enters the weighing device 8, the weighing device 8 accurately weighs each material and transmits the weighing data to the controller. The controller determines the classification of the material based on the weighing data and sends a signal to the sorting device 9. The sorting device 9 classifies the material according to the instructions of the controller and distributes the materials of different weights or specifications to the corresponding receiving channels. The sorted materials enter the receiving device 10. A container is placed at the bottom of each receiving channel for collecting materials of the corresponding category. The receiving device 10 ensures that the material can enter the container smoothly and prevents the material from being mixed or damaged during the receiving process.

[0050] The technical effects achieved through the implementation of the above technical solution are as follows:

[0051] Efficient transmission and weighing: By precisely controlling the transmission speed and material frequency, materials are ensured to enter the weighing device 8 one by one, thus avoiding weighing errors.

[0052] Accurate sorting and collection: The sorting device 9 accurately distributes the materials according to the weighing results, and the receiving device 10 efficiently collects the sorted materials to ensure accurate classification and orderly collection.

[0053] System stability and reliability: The entire system, from feeding, transmission, weighing, sorting to receiving, all links work closely together to ensure smooth and efficient transmission and weighing processes, reduce material loss and damage, and improve work efficiency and accuracy.

[0054] In summary, this embodiment achieves efficient, accurate and stable operation of the sorting and weighing machine by describing in detail the structural composition, working principle and technical details of each component, ensuring smooth and error-free operation of the entire process from material feeding to weighing, sorting and receiving.
