Description

Technical Field

[0001] This utility model relates to the field of plastic cup production technology, and in particular to a plastic cup screening device. Background Technology

[0002] After the plastic cups are produced, they have various applications. Some plastic cups need to be repackaged, while others need to be mixed with other types of plastic cups according to different requirements. This necessitates precise screening and sorting of the plastic cups.

[0003] In practical use, there are significant problems in the current process of screening and sorting plastic cups. The existing screening system is a rotating shaft structure with multiple shafts rotating synchronously at different distances. Plastic cups are placed on the shafts and fall into the shafts with different spacing according to their size, thus achieving screening. In this method, plastic cups need to be released one by one. If multiple plastic cups are released at the same time, they are prone to collisions, causing smaller plastic cups to fall into the shafts with larger spacing. Furthermore, due to the existence of errors, the screened plastic cups cannot be transported directly and need to be screened again before transportation. This makes it impossible to efficiently meet the diverse production needs in the production process and greatly limits the flexibility and efficiency of plastic cup production. Utility Model Content

[0004] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a plastic cup screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A plastic cup screening device includes a conveying assembly and a screening assembly. The screening assembly is located on the upper right side of the conveying assembly, and has a feed inlet at its upper end. The screening assembly includes two sets of distribution ports, a left distribution port and a right distribution port. The opening of the left distribution port is smaller than that of the right distribution port. The lower end of each distribution port is inclined, and the inclined surfaces of each set of distribution ports are opposite. A feed inlet is fixed at the upper end of each distribution port, and there are two sets of feed inlets, which are perpendicularly corresponding to the positions of the two sets of distribution ports. The conveying assembly includes a conveying bracket, on which several distribution blocking plates are slidably mounted. The positions of the distribution blocking plates correspond to the distribution ports. When a distribution blocking plate is positioned at the opening of the right distribution port, the opening of the left distribution port is opened.

[0006] Preferably, hydraulic rods are installed on both sides of the conveying support, and a material distribution block plate is installed at the front end of the hydraulic rods.

[0012] This utility model has the following advantages and beneficial effects: In this invention, two sets of inlets can each introduce multiple different plastic cups, which, in conjunction with two sets of vertically aligned and oppositely inclined dispensing ports, precisely plan the plastic cup screening path to meet diverse screening needs. The conveying bracket of the conveying component provides stable support, and the hydraulic rod drives the dispensing blocking plate to flexibly control the opening and closing of the dispensing ports, achieving precise dispensing.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Example like Figures 1-4 As shown, a plastic cup screening device includes a conveying assembly 1 and a screening assembly 2. The screening assembly 2 is located on the upper right side of the conveying assembly 1. The screening assembly 2 has a feed inlet 3 at its upper end and includes a distribution port 21. The distribution port 21 includes a left distribution port 211 and a right distribution port 212. The opening of the left distribution port 211 is smaller than the opening of the right distribution port 212. There are two sets of distribution ports 21, and the lower end of each distribution port 21 is inclined. The inclined surfaces of each set of distribution ports 21 are opposite. In the state, the upper end of the distribution port 21 is fixed with a feed port 3. There are two sets of feed ports 3, and the positions of the two sets of feed ports 3 are perpendicular to the positions of the two sets of distribution ports 21. The conveying component 1 includes a conveying bracket 11. Hydraulic rods 23 are installed on both sides of the conveying bracket 11. A distribution blocking plate 22 is installed at the front end of the hydraulic rod 23. The position of the distribution blocking plate 22 is corresponding to the distribution port 21. When the distribution blocking plate 22 is placed at the opening position of the right distribution port 212, the opening of the left distribution port 212 is opened.

[0018] During operation, the feed inlet 3 is the entrance for the plastic cups to enter the screening component 2. There are two sets of distribution ports 21, each with an opposite slope. This design allows the plastic cups to slide in different directions based on their characteristics and screening requirements. First, the two distribution baffles 22 are placed below the right distribution port 212. The plastic cup is then placed into the left distribution port 211. Since the left distribution port 211 is smaller than the right distribution port 212, the smaller plastic cup slides from the opening of the left distribution port 211 onto the conveyor belt 16, while the larger plastic cup slides through. When a larger plastic cup blocks the opening of the left feed port 211, the larger plastic cup is removed and placed into the right feed port 212. During the removal of the plastic cup, the smaller plastic cup still falls onto the conveyor belt 16. After the plastic cups in the right feed port 212 fill the feed port 21, the feed blocking plate 22 slides to the bottom of the left feed port 211. At this time, the opening of the right feed port 212 is opened, and the larger plastic cup falls onto the conveyor belt 16 from the opening of the right feed port 212. At the same time, new plastic cups are continuously added into the left feed port 211.

[0019] The conveying bracket 11 provides a supporting structure for the entire conveying assembly 1; the hydraulic rod 23, driven by hydraulic pressure, can precisely control the opening and closing of the material distribution blocking plate 22, achieving flexible control of the material distribution port 21. It can quickly adjust the opening and closing state of the material distribution port 21 according to different screening requirements. The position of the material distribution blocking plate 22 corresponds to the material distribution port 21; when one material distribution port 21 in a group is opened, the other material distribution port 21 will be blocked. This design allows for flexible selection of the plastic cup's discharge path according to the screening requirements, achieving precise screening and material distribution, improving production efficiency and flexibility, and meeting diverse production needs.

[0020] like Figures 1-3 As shown, the upper end of the conveying bracket 11 is fixed to the material distribution baffle 17 by the connecting plate 4. The function of the connecting plate 4 is to establish a reliable connection between the conveying bracket 11 and the material distribution baffle 17, and to stably transmit the supporting force of the conveying bracket 11 to the material distribution baffle 17.

[0021] like Figures 1-2 As shown, drive rods 15 are installed at both ends of the conveyor bracket 11, and a conveyor belt 16 is installed in the middle of the drive rods 15. Driven by the drive rods 15, the conveyor belt 16 smoothly conveys the plastic cup from one end of the equipment to the other end.

[0022] like Figures 1-4 As shown, a material distribution baffle 17 is fixed in the middle of the connecting plate 4. The material distribution baffle 17 is located in the middle of the material distribution port 21. The material distribution baffle 17 can separate plastic cups of different types or specifications according to the preset screening criteria, so that the corresponding type of plastic cup can only flow out from the corresponding material distribution port 21 (smaller plastic cups are at the left end of the material distribution baffle 17, and larger plastic cups are at the right end of the material distribution baffle 17), avoiding the mixing of different plastic cups and achieving accurate material discharge.

[0023] The conveyor belt 16 is made of hard rubber, which gives it good wear resistance and allows it to withstand long-term, high-intensity use. Even during frequent conveying of plastic cups, it is not easy for it to wear out or break.

[0024] A conveyor motor 12 is installed at the lower right end of the conveyor bracket 11. Synchronous pulleys 13 are installed on the front side of the conveyor motor 12 and the front side of the drive rod 15. The two sets of synchronous pulleys 13 are connected by a synchronous belt 14. The teeth of the synchronous pulleys 13 are precisely meshed with the tooth grooves of the synchronous belt 14. When the conveyor motor 12 is running, the synchronous pulleys 13 on the front side of the motor rotate accordingly. With the help of the synchronous belt 14, the torque of the motor is transmitted to the synchronous pulleys 13 on the front side of the drive rod 15 without loss and with precision, thereby driving the drive rod 15 to rotate.

[0025] The drive motor that drives the conveyor belt is a stepper motor. The pulse frequency of the stepper motor can be precisely controlled according to the specific requirements of the screening process, thereby accurately adjusting the running speed and displacement of the conveyor belt 16 to make the conveyor belt 16 vibrate. During the conveying of plastic cups, since the conveyor belt 16 is connected to the screening component 2 through the material distribution baffle 17 and the connecting plate 4, the vibration of the conveyor belt 16 drives the screening component 2 to vibrate, preventing the plastic cups from clogging in the screening component 2 and increasing the screening efficiency.

[0026] When using the plastic cup screening equipment, different types or specifications of plastic cups are first introduced into the screening component 2 through the two sets of feed inlets 3. The conveyor motor 12 at the lower right side of the conveyor bracket 11 is started, and its front synchronous wheel 13 rotates under the drive of the motor. The torque is accurately transmitted to the front synchronous wheel 13 of the drive rod 15 through the synchronous belt 14. The drive rod 15 rotates, driving the rigid rubber conveyor belt 16 in the middle to run. During the conveying process, the pulse frequency and number of the stepper motor as the drive motor can be precisely controlled according to the screening process, and the running speed and displacement of the conveyor belt 16 can be precisely adjusted to ensure that the plastic cups can reach the screening component 2 at a suitable speed and position. The material distribution baffle 17, which is fixed to the upper end of the conveyor bracket 11 via the connecting plate 4, separates different plastic cups according to the preset screening standards when there is no need for mixing, so as to achieve accurate material discharge. The entire equipment can efficiently and flexibly complete the screening and material distribution of plastic cups and meet diverse production needs.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
