Description

Technical Field

[0001] This utility model relates to the technical field of processing equipment in the filling industry, specifically to an empty can rejection device for a can line. Background Technology

[0002] Existing methods for removing empty cans generally rely on manual monitoring, which requires dedicated monitoring stations, resulting in wasted manpower. Furthermore, the accuracy of monitoring is highly dependent on the worker's attentiveness, necessitating continuous on-site observation by designated personnel. This inherent limitation makes it easy for empty cans to be missed. Another more conventional method is magnetic attraction for removal. However, this method requires specialized equipment or personnel to collect the attracted cans, and it only works on ferrous cans, not plastic or aluminum cans, further limiting its applicability. Therefore, a can-pulling line empty can removal device is needed to meet these needs. Utility Model Content

[0003] The purpose of this invention is to provide an empty can rejection device for can delivery lines, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an empty can rejection device for a can-pulling line, comprising a device body, a drive box installed at one end of the device body, a drive motor installed at one end of the drive box, a push rod installed at one end of the drive motor, a flexible sheet installed at one end of the push rod, a transmission plate provided on the side of the device body, a detection sensor installed at one end of the transmission plate, a conveyor belt installed inside the transmission plate, and a guide plate installed on the side of the transmission plate.

[0005] Preferably, a lifting rod is installed at one end of the main body of the device, and one end of the lifting rod is connected to the drive box.

[0006] Preferably, the side of the transmission plate is provided with a sliding groove, and a slider is installed at one end of the guide plate, and the sliding groove is adapted to the slider.

[0007] Preferably, a fixing rod is installed inside the guide plate, and multiple blocking strips are installed on the side of the fixing rod.

[0008] Preferably, a fixing plate is installed at one end of the main body of the device, a limiting groove is formed in the fixing plate, a limiting block is installed in the limiting groove, a threaded hole is formed at one end of the limiting block, and a rotating rod is rotatably installed at one end of the fixing plate.

[0009] Preferably, a pressure plate is installed at one end of the limiting block, and one end of the threaded hole is threaded to the side of the rotating rod.

[0010] Preferably, the transmission plate is adapted to the fixing plate, and the side of the transmission plate abuts against the side of the pressure plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) By setting up a drive box and a drive motor, when the can is being transported on the conveyor belt, the detection sensor detects the can passing through and determines whether the can is empty. When an empty can is detected, the detection sensor sends a sensor signal to the control system, which then starts the control drive motor to move the push rod forward. The can is pushed into the guide plate on one side of the transmission plate and removed by contacting one end of the flexible sheet with the can wall.

[0013] (2) By setting up a guide plate and lifting rod, the can falls into the guide plate and is blocked by multiple blocking strips on the side of the fixing rod, which slows down the falling speed of the can and prevents the can from falling directly, thus protecting the shape of the can. The pressure plate can be moved by rotating the rotating rod. One end of the transmission plate is clamped by the fixing plate and the pressure plate, which fixes the position of the main body of the device, making it more stable when pushed by the drive box and improving the applicability of the main body of the device.

[0021] 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 protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: an empty can rejection device for a can delivery line, comprising a main body 1, a drive box 2 installed at one end of the main body 1, a drive motor 3 installed at one end of the drive box 2, a push rod 4 installed at one end of the drive motor 3, a flexible sheet 5 installed at one end of the push rod 4, a transmission plate 6 provided on the side of the main body 1, a detection sensor 7 installed at one end of the transmission plate 6, a conveyor belt 8 installed inside the transmission plate 6, a guide plate 9 installed on the side of the transmission plate 6, a fixing rod 13 installed inside the guide plate 9, and multiple blocking strips 14 installed on the side of the fixing rod 13. When the can is conveyed on the conveyor belt 8, it passes through the detection sensor... The device 7 uses multiple sets of sensors to detect the cans and determine whether they are empty. When a can is empty, it sends a sensor signal to the main body 1, which triggers the drive box 2 via a pre-compiled system. The drive motor 3 moves the push rod 4 forward, causing one end of the flexible sheet 5 to contact the side of the can, pushing the can into the guide plate 9. The fixed rod 13 and the blocking strip 14 inside the guide plate 9 provide some resistance when the can falls, preventing it from falling too fast and causing impacts that could deform the can. Through the cooperation of the detection sensors 7 and the drive box 2, empty cans are rejected, improving the pass rate of the production line.

[0023] Example 2: As Figure 2 and 4 As shown, a lifting rod 10 is installed at one end of the main body 1 of the device, and one end of the lifting rod 10 is connected to the drive box 2. A sliding groove 11 is opened on the side of the transmission plate 6. A slider 12 is installed at one end of the guide plate 9. The sliding groove 11 and the slider 12 are adapted to each other. A fixing plate 15 is installed at one end of the main body 1 of the device. A limit groove 16 is opened in the fixing plate 15. A limit block 17 is installed in the limit groove 16. A threaded hole 18 is opened at one end of the limit block 17. A rotating rod 19 is rotatably installed at one end of the fixing plate 15. A pressure plate 20 is installed at one end of the limit block 17. One end of the threaded hole 18 is threaded to the side of the rotating rod 19. The transmission plate 6 is adapted to the fixing plate 15. The side of the transmission plate 6 abuts against the side of the pressure plate 20. When the drive box 2 is adjusted... When the push rod 4 is pushed, the main body 1 of the device may shake to a certain extent. By rotating the rotating rod 19, the limiting block 17 is moved to slide in the limiting groove 16, thereby moving the pressure plate 20. The pressure plate 20 is clamped by the fixing plate 15 and installed at the bottom of the transmission plate 6, so that the position of the main body 1 of the device is fixed. When it is necessary to adjust the height of the drive box 2, the lifting rod 10 is raised to drive the drive box 2 to rise. When it is necessary to adjust the position of the rejection, one end of the guide plate 9 can be lifted and the slider 12 slides in the slide groove 11 to move the guide plate 9 to a suitable position. After being lowered, the slider 12 at one end of the guide plate 9 is supported by the weight of the guide plate 9 and abuts against the inner wall of the slide groove 11, so that the slider 12 will not slide. The remaining features are the same as in embodiment 1.

[0024] The working principle is as follows: When the can is conveyed on the conveyor belt 8, the detection sensor 7 detects the can through multiple sets of sensors to determine whether the can is empty. When the can is empty, a sensor signal is sent to the main body 1 of the device. The pre-compiled system starts the drive box 2 to react, and the drive motor 3 moves the push rod 4 forward, so that one end of the flexible sheet 5 contacts the side of the can, pushing the can into the guide plate 9. The fixing rod 13 and the blocking strip 14 in the guide plate 9 provide a certain degree of obstruction when the can falls, preventing the can from falling too fast and causing collisions and deformation. When the drive box 2 moves the push rod 4, the main body 1 of the device may shake a little. By rotating the rotating rod 1, the device can be controlled. 9. The limiting block 17 slides within the limiting groove 16, thereby moving the pressure plate 20. The pressure plate 20 is clamped by the fixing plate 15 and installed at the bottom of the transmission plate 6, fixing the position of the main body 1 of the device. When the height of the drive box 2 needs to be adjusted, the lifting rod 10 is raised to drive the drive box 2 to rise. When the rejection position needs to be adjusted, one end of the guide plate 9 can be lifted, and the slider 12 slides within the slide groove 11 to move the guide plate 9 to the appropriate position. After being lowered, the slider 12 at one end of the guide plate 9 is pressed against the inner wall of the slide groove 11 by the weight of the guide plate 9, preventing the slider 12 from sliding. Through the cooperation of the detection sensor 7 and the drive box 2, empty cans are rejected, improving the pass rate of the production line.
