Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene product production equipment, and in particular to a waste rejection device. Background Technology

[0002] On June 17, 2016, the applicant filed a Chinese application (CN201620602717.8) entitled "A Novel Waste Removal Device," which discloses a device comprising a frame, a conveyor mounted on the frame, the conveyor including a drive wheel rotatably mounted on the frame, a driven wheel rotatably mounted on the frame, a conveyor belt covering the drive wheel and the driven wheel, and a drive device mounted on the frame for driving the drive wheel to rotate. The conveyor belt has a plurality of through holes evenly distributed on it. Two adsorption devices for adhering items tightly to the conveyor belt are located on the inner side of the frame, and an air blowing device is located between the two adsorption devices. This patent discloses a waste removal structure commonly found in the field of disposable hygiene products.

[0003] Existing waste removal structures often use air blowing to remove waste. While this can effectively remove waste, the air blowing uses high-pressure air, resulting in a large volume of waste gas and slow high-speed response. Furthermore, it is difficult to remove waste items with small intervals, which may lead to waste removal failure. In such cases, manual sorting is still required, resulting in low work efficiency. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model provides a waste rejection device, which mainly solves the problem of low accuracy of waste rejection devices in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rejecting device includes a frame, a clamping and conveying mechanism, a rejecting mechanism, a reject collection box, and a reversing conveying mechanism. The clamping and conveying mechanism is mounted on the frame and includes an upper belt conveyor assembly and a lower belt conveyor assembly. A first conveying channel for conveying products is formed between the upper and lower belt conveyor assemblies. The clamping and conveying mechanism and the reversing conveying mechanism are spaced apart. The rejecting mechanism and the reject collection box are located between the clamping and conveying mechanism and the reversing conveying mechanism, with the rejecting mechanism distributed on the upper side of the reject collection box and the upper side of the first conveying channel. The rejecting mechanism includes a bracket, a support, a servo motor, a coupling, a rotating shaft, bearings, and a rejecting plate. The bracket is welded to the frame, and the support is locked to the bracket. The two ends of the rotating shaft are rotatably mounted on the support via bearings. The servo motor is connected to the rotating shaft via a coupling. The rejecting plate is mounted on the rotating shaft. When there is a defective product, the rotating shaft rotates, causing one end of the rejecting plate to swing downwards and enter the first conveying channel.

[0007] Furthermore, the reversing conveying mechanism includes a fixed base, a connecting assembly, a drive cylinder, an upper pulley assembly, and a lower pulley assembly. A second conveying channel is formed between the upper pulley assembly and the lower pulley assembly. The upper pulley assembly includes an upper drive roller, an upper driven roller, and an upper belt wound around the upper drive roller and the upper driven roller. The lower pulley assembly includes a lower drive roller, a lower driven roller, and a lower belt wound around the lower drive roller and the lower driven roller. The fixed base is mounted on the frame. The upper drive roller and the lower drive roller are rotatably mounted on the fixed base. The upper driven roller and the lower driven roller are connected by a connecting assembly. The two ends of the drive cylinder are connected to the frame and the connecting assembly, respectively. The drive cylinder drives the upper driven roller and the lower driven roller to move through the connecting assembly, thereby moving the output end of the second conveying channel.

[0008] Furthermore, the connecting assembly includes an upper connecting seat connected to the upper pulley assembly, a lower connecting seat connected to the lower pulley assembly, and a connecting rod connecting the upper connecting seat and the lower connecting seat. The upper end of the upper connecting seat is provided with a mounting part for connecting to the drive cylinder.

[0009] Furthermore, the waste removal plate includes a straight plate, a Z-shaped plate, and two side plates. One end of the Z-shaped plate is fixed to the back of the straight plate and located on the longitudinal side of the vertical line of the straight plate. The other end of the Z-shaped plate is located on a rotating shaft. The two side plates are located on the transverse sides of the Z-shaped plate and are connected to the straight plate.

[0010] Furthermore, both ends of the straight plate are provided with arc-shaped guide portions.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This rejection device, by setting up a rejection mechanism including a servo motor driving a rotating shaft to drive a rejection plate, when there are defective products, the rotating shaft rotates, causing one end of the rejection plate to swing downwards and enter the first conveying channel, so that the defective products in the first conveying channel are pushed into the waste collection box by the rejection plate. This mechanical rejection method can more accurately reject defective products. At the same time, the servo motor drives the rotating shaft to rotate, realizing the swing rejection of the rejection plate, improving the response speed and effectively solving the problem of low accuracy of rejection devices in the prior art, thus improving the accuracy and success rate of rejection. Furthermore, the clamping conveying mechanism forms a first conveying channel for conveying products through the upper belt conveying assembly and the lower belt conveying assembly. The rejection mechanism and the waste collection box are located between the clamping conveying mechanism and the reversing conveying mechanism, and the rejection mechanism is distributed on the upper side of the waste collection box and the upper side of the first conveying channel. This layout makes the rejection process smooth, the structure stable and reliable, and helps to improve the working stability of the entire rejection device. Attached Figure Description

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] The embodiment of this utility model is as follows:

[0018] refer to Figures 1 to 4As shown, a waste rejection device includes a frame 1, a clamping and conveying mechanism 2, a waste rejection mechanism 3, a waste collection box 4, and a reversing conveying mechanism 5. The clamping and conveying mechanism 2 is mounted on the frame 1 and includes an upper belt conveyor assembly 21 and a lower belt conveyor assembly 22. A first conveying channel 23 for conveying products is formed between the upper belt conveyor assembly 21 and the lower belt conveyor assembly 22. The clamping and conveying mechanism 2 and the reversing conveying mechanism 5 are spaced apart. The waste rejection mechanism 3 and the waste collection box 4 are located between the clamping and conveying mechanism 2 and the reversing conveying mechanism 5, with the waste rejection mechanism 3 positioned above the waste collection box 4. The rejection mechanism 3 is distributed on the upper side of the first conveying channel 23. It includes a bracket 31, a support 32, a servo motor 33, a coupling 34, a rotating shaft 35, a bearing 36, and a rejection plate 37. The bracket 31 is welded to the frame 1, and the support 32 is locked to the bracket 31. The two ends of the rotating shaft 35 are rotatably mounted on the support 32 through the bearings 36. The servo motor 33 is connected to the rotating shaft 35 through the coupling 34. The rejection plate 37 is mounted on the rotating shaft 35. When there is a defective product, the rotating shaft 35 rotates, causing one end of the rejection plate 37 to swing downward and enter the first conveying channel 23.

[0019] This rejection device employs a rejection mechanism comprising a servo motor 33 driving a rotating shaft 35 to move a rejection plate 37. When a defective product is present, the rotating shaft 35 rotates, causing one end of the rejection plate 37 to swing downwards into the first conveying channel 23. This allows the defective product in the first conveying channel 23 to be pushed into the waste collection box 4 by the rejection plate 37. This mechanical rejection method can more accurately remove defective products. Simultaneously, the servo motor 33 drives the rotating shaft 35 to rotate, realizing the swing rejection of the rejection plate 37, thus improving response speed. This effectively solves the problem of low accuracy in existing rejection devices, improving the accuracy and success rate of rejection. Furthermore, the clamping and conveying mechanism 2 forms a first conveying channel 23 for conveying products through the upper belt conveying assembly 21 and the lower belt conveying assembly 22. The rejection mechanism 3 and the waste collection box 4 are located between the clamping and conveying mechanism 2 and the reversing conveying mechanism 5, with the rejection mechanism 3 distributed on the upper side of the waste collection box 4 and the upper side of the first conveying channel 23. This layout makes the rejection process smooth, the structure stable and reliable, and helps to improve the working stability of the entire rejection device.

[0020] Specifically, the reversing conveying mechanism 5 includes a fixed base 51, a connecting assembly 52, a drive cylinder 53, an upper pulley assembly 54, and a lower pulley assembly 55. A second conveying channel 56 is formed between the upper pulley assembly 54 and the lower pulley assembly 55. The upper pulley assembly 54 includes an upper drive roller 541, an upper driven roller 542, and an upper belt 543 wound around the upper drive roller 541 and the upper driven roller 542. The lower pulley assembly 55 includes a lower drive roller 554, a lower driven roller 552, and a lower belt 553 wound around the lower drive roller 554 and the lower driven roller 552. The fixed base 51 is mounted on the frame 1. The upper drive roller 541 and the lower drive roller 551 are rotatably mounted on the fixed base 51. The upper driven roller 542 and the lower driven roller 552 are connected via the connecting assembly 52. The cylinder 53 is connected to the frame 1 and the connecting assembly 52 at both ends. The cylinder 53 drives the upper driven roller 542 and the lower driven roller 552 to move through the connecting assembly 52, so that the output end of the second conveying channel 56 moves. This allows the output end position of the second conveying channel 56 to be adjusted according to actual production needs, increasing the flexibility of the second conveying channel 56 and realizing the diversion function, thereby improving the subsequent packaging efficiency. The upper pulley assembly 54 and the lower pulley assembly 55 form the second conveying channel 56 through the upper drive roller 541, the upper driven roller 542, the upper belt 543, and the lower drive roller 551, the lower driven roller 552, and the lower belt 553, respectively. This pulley assembly design can provide stable conveying power, ensure that the product is transported smoothly in the second conveying channel, reduce shaking and deviation during the conveying process, and improve the conveying quality.

[0021] Furthermore, the connecting assembly 52 includes an upper connecting seat 521 connected to the upper pulley assembly 54, a lower connecting seat 522 connected to the lower pulley assembly 55, and a connecting rod 523 connecting the upper connecting seat 521 and the lower connecting seat 522. The upper end of the upper connecting seat 521 is provided with a mounting part 524 for connecting to the drive cylinder 53, which makes the installation and connection between the connecting assembly 52 and the drive cylinder 53, as well as the upper pulley assembly 54 and the lower pulley assembly 55, more convenient and quick, reduces the installation difficulty, improves the assembly efficiency, and also facilitates subsequent maintenance and repair work. The upper connecting seat 521 and the lower connecting seat 522 are connected by the connecting rod 523 to form an integral structure, which can better transmit the force of the drive cylinder 53, so that the upper driven roller 542 and the lower driven roller 552 move synchronously, ensuring the stability and consistency of the adjustment of the second conveying channel 56, and enhancing the integrity and reliability of the entire reversing conveying mechanism 5 structure.

[0022] Furthermore, the rejection plate 37 includes a straight plate 101, a Z-shaped plate 102, and two side plates 103. One end of the Z-shaped plate 102 is fixed to the back of the straight plate 101 and located on the longitudinal side of the vertical line of the straight plate 101. The other end of the Z-shaped plate 102 is located on the rotating shaft 35. The two side plates 103 are located on the transverse sides of the Z-shaped plate 102 and connected to the straight plate 101. This makes the force on the rejection plate 37 more uniform and reasonable when it swings to reject defective products, which can improve the strength and stability of the rejection plate 37, extend its service life, and also help to more effectively remove defective products from the first conveying channel 23. In addition, during the swinging process of the rejection plate 37, defective products can be separated more quickly and effectively, improving rejection efficiency, reducing rejection time, and thus improving the working efficiency of the entire rejection device.

[0023] In this embodiment, both ends of the straight plate 101 are provided with arc-shaped guide portions 104. When the rejection plate 37 swings to reject defective products, the arc-shaped guide portions 104 can play a buffering and guiding role, avoiding rigid collision between the end of the straight plate 101 and the product, reducing damage to the product, and ensuring the integrity of the product. Especially for some easily damaged products, this design can effectively improve the product pass rate. In addition, the design of the arc-shaped guide portions 104 makes the rejection plate 37 more smoothly contacting and separating from the product, reducing jamming and obstruction in the rejection process, making the rejection action smoother, improving the stability and reliability of rejection, and further ensuring the normal operation of the rejection device.
