Description

Technical Field

[0001] This invention belongs to the technical field of vegetable processing equipment, and more specifically, it relates to a cabbage packaging machine. Background Technology

[0002] Chinese cabbage is a staple vegetable in Northeast and North China during winter and spring. In supermarkets, Chinese cabbage needs to be packaged before sale, typically by wrapping it with tape to prevent the leaves from scattering or getting damaged during the sales process. Currently, supermarket Chinese cabbage is packaged manually. This involves staff repeatedly taking vegetables, taking tape, wrapping tape, and placing vegetables back in, resulting in a heavy workload and low efficiency. Furthermore, the method of manually wrapping the tape is unpredictable, and the length of the tape used varies from person to person, leading to tape waste and inconsistent packaging results. Summary of the Invention

[0003] The purpose of this invention is to provide a cabbage packaging machine that can automate the packaging of cabbage, improve packaging efficiency and quality, and control the use of tape, thereby saving tape consumption.

[0004] To achieve the above objectives, the present invention provides a cabbage packaging machine, comprising a frame, a conveying mechanism, a glue supply mechanism, a flipping mechanism, a cutting mechanism, and a controller. The conveying mechanism includes a first driving device and two conveyor belts, which are spaced apart and rotatably connected to the frame. The first driving device is drivenly connected to each conveyor belt. The glue supply mechanism includes a glue-dispensing shaft and a glue-guiding roller arranged at intervals along the conveying direction of the cabbage, which are rotatably connected to the frame. The flipping mechanism includes a driving roller, a rotating roller, a second driving device, and a recognition device. The driving roller and the rotating roller are arranged at intervals along the conveying direction of the cabbage and rotatably connected to the frame. The driving roller is located between the glue-guiding roller and the rotating roller. The second driving device is drivenly connected to the driving roller. The recognition device is connected to the frame and located on one side of the rotating roller. The cutting mechanism is located between the glue-guiding roller and the driving roller. The controller is electrically connected to the first driving device, the second driving device, the recognition device, and the cutting mechanism.

[0005] Preferably, the conveying mechanism further includes a drive shaft and a driven shaft. The driven shaft and the drive shaft are arranged sequentially at intervals along the conveying direction of the Chinese cabbage and are rotatably connected to the frame. The guide roller, drive roller and rotating roller are located between the driven shaft and the drive shaft, respectively. The glue-dispensing shaft is arranged at intervals below the driven shaft. Each conveyor belt is sleeved on the drive shaft and the driven shaft. The first drive device is driven and connected to the drive shaft.

[0006] Preferably, the first driving device includes a first motor, a first driving pulley, a first driven pulley, and a first synchronous belt. The first motor is connected to the frame, the first driving pulley is connected to the output shaft of the first motor, the first driven pulley is connected to one end of the drive shaft, and the first driven pulley and the first driving pulley are connected by the first synchronous belt.

[0007] Preferably, the glue supply mechanism further includes a guide roller rotatably connected to the frame, the guide roller being located between the driven shaft and the guide roller.

[0008] Preferably, the number of guide rollers is two.

[0009] Preferably, a tape roll is fitted onto the tape release shaft, and the tape is pulled out from the tape roll and passes sequentially around the driven shaft and the guide roller, with the adhesive side of the tape end located above the guide roller.

[0010] Preferably, the second drive device includes a second motor, a second drive pulley, a second driven pulley, and a second synchronous belt. The second motor is connected to the frame, and the output shaft of the second motor is connected to the second drive pulley. The second driven pulley is connected to the shaft of the drive roller, and the second drive pulley and the second driven pulley are connected by the second synchronous belt.

[0011] Preferably, the cutting mechanism includes a third drive unit and a tape cutter, wherein the third drive unit is connected to the tape cutter to drive the tape cutter to rotate and cut the tape.

[0012] Preferably, the frame includes two longitudinal beams spaced apart, each longitudinal beam is connected to two columns spaced apart, and a crossbeam is connected between the two longitudinal beams, with the cutting mechanism connected to the crossbeam.

[0013] Preferably, each conveyor belt is fitted onto the outside of a longitudinal beam, and the two longitudinal beams are arranged in a one-to-one correspondence with the two conveyor belts.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: Adhesive tape is supplied to the cabbage via a glue supply mechanism. The tape-coated cabbage is then conveyed to a turning mechanism via a conveyor mechanism. When the identification device detects that the cabbage is on the drive roller and rotating roller, the conveyor mechanism stops, and the drive roller and rotating roller work together to turn the cabbage over, wrapping the tape around its exterior. After the turning mechanism stops, the cutting mechanism starts and cuts the tape, completing the packaging of the cabbage. This effectively prevents the cabbage from scattering or being damaged during sale, reducing waste. This invention automates the tape wrapping and cutting process through a conveyor mechanism, glue supply mechanism, turning mechanism, and cutting mechanism mounted on a frame, replacing manual operation, improving packaging efficiency and quality, and reducing tape waste.

The first motor 204 is electrically connected to the controller. During operation, the two ends of the cabbage are placed on two conveyor belts 201 respectively. The first motor 204 starts, causing the two conveyor belts 201 to run synchronously, achieving stable transportation of the cabbage.

[0020] In this embodiment, the glue supply mechanism 300 includes a glue-dispensing shaft 301 and a glue-guide roller 302 arranged sequentially at intervals along the conveying direction of the Chinese cabbage. The glue-dispensing shaft 301 and the glue-guide roller 302 are rotatably connected to the frame 100, with the glue-guide roller 302 located between the driven shaft 203 and the driving shaft 202. The glue-dispensing shaft 301 is spaced below the driven shaft 203. The glue supply mechanism 300 also includes a guide roller 303 rotatably connected to the frame 100, located between the driven shaft 203 and the guide roller 302. A tape roll 600 is fitted onto the glue-dispensing shaft 301. After the tape is pulled out from the tape roll 600, it passes sequentially around the driven shaft 203 and the guide roller 303, with the adhesive side of the tape end located above the guide roller 302. The tape is tensioned by the driven shaft 203 and the guide roller 303, preventing the tape from falling off. The guide rollers 302 are of two types, or more, to increase the contact area between the cabbage and the conveyor belt, thus ensuring full adhesion between them. During operation, the adhesive side of the conveyor belt faces upwards, passing over the driven shaft 203, then through the gap between the guide rollers 303 and 302 from below the steering roller 303. The adhesive side of the end of the conveyor belt is placed above the guide roller 302, and the cabbage is placed on the guide roller 302, making contact between the cabbage and the conveyor belt. Both ends of the cabbage are placed on the two conveyor belts 201, which then move the cabbage and conveyor belt towards the turning mechanism 400.

[0021] In this embodiment, the flipping mechanism 400 includes a drive roller 401, a rotating roller 402, a second drive device, and an identification device. The drive roller 401 and the rotating roller 402 are sequentially spaced apart along the conveying direction of the Chinese cabbage and rotatably connected to the frame 100. The drive roller 401 and the rotating roller 402 are respectively located between the driven shaft 203 and the drive shaft 202. The drive roller 401 is located between the guide roller 302 and the rotating roller 402. The second drive device is drivenly connected to the drive roller 401. The identification device is connected to the frame 100 and located on one side of the rotating roller 402. The second drive device includes a second motor 403, a second drive pulley 404, a second driven pulley 405, and a second synchronous belt 406. The second motor 403 is connected to the frame 100, and the output shaft of the second motor 403 is connected to the second drive pulley 404. The second driven pulley 405 is connected to the shaft of the drive roller 401. The second drive pulley 404 and the second driven pulley 405 are connected by the second synchronous belt 406. The identification device includes a photoelectric sensor 407. The photoelectric sensor 407 and the second motor 403 are electrically connected to the controller. During operation, when the photoelectric sensor 407 detects that the cabbage with adhesive tape has moved above the drive roller 401 and the rotating roller 402, the first motor 204 stops running and the second motor 403 starts. The drive roller 401 drives the cabbage to rotate in the direction of cabbage transmission, thereby causing the adhesive tape to wrap around the outside of the cabbage. After a preset time is reached, the second motor 403 stops running and the cutting mechanism 500 runs to cut the adhesive tape. After the cutting mechanism 500 stops running, the packaged cabbage can be removed or the first motor 204 can be started, and the conveyor belt 201 will transport the cabbage to the next process.

[0022] In this embodiment, the cutting mechanism 500 is located between the guide roller 302 and the drive roller 401. The cutting mechanism 500 includes a third driving device and a tape cutter 501. The third driving device is connected to the tape cutter 501 to drive the tape cutter 501 to rotate and cut the tape. The third driving device includes a third motor 502, the output shaft of which is connected to the tape cutter 501. The tape cutter 501 is located on one side of the tape. The third motor 502 drives the tape cutter 501 to rotate toward the tape, thereby cutting the tape. The third motor 502 is electrically connected to the controller.

[0023] In this embodiment, the frame 100 includes two spaced-apart longitudinal beams 101, each longitudinal beam 101 is connected to two spaced-apart uprights 102, and a crossbeam 103 connects the two longitudinal beams 101. The cutting mechanism 500 is connected to the crossbeam 103.

The crossbeam 103 is located between the guide roller 302 and the drive roller 401. The third motor 502 is fixedly installed on the crossbeam 103. The crossbeam 103 is not only used to install the third motor 502, but also to make the frame 100 structure more stable. Two columns 102 on the side near the dispensing shaft 301 are respectively connected to a bearing seat 304. The bearing seats 304 on the two columns 102 are rotatably connected to both ends of the dispensing shaft 301. A mounting beam 104 is connected between the two columns 102 connected to the same longitudinal beam 101. The mounting beam 104 is located below the longitudinal beam 101. The second motor 403 is fixedly installed on the mounting beam 104. The first motor 204 is fixedly installed on one of the columns 102 near it.

[0024] The working principle of the cabbage packaging machine according to this invention is as follows: During operation, the cabbage is placed on the guide roller 302, so that the cabbage comes into contact with the tape. Both ends of the cabbage are placed on the two conveyor belts 201 respectively. The two conveyor belts 201 drive the cabbage with tape to move towards the flipping mechanism 400. When the photoelectric sensor 407 detects that the cabbage is on the drive roller 401 and the rotating roller 402, the conveyor belt 201 stops running. At this time, the drive roller 401 rotates to one side of the rotating roller 402, so that the tape is wrapped around the outside of the cabbage. After a preset time is reached, the drive roller 401 stops rotating, and the tape cutter 501 rotates to one side of the tape until it is cut, thus completing the packaging of the cabbage.

[0025] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
