[0074] See also Figures 1 to 9 The present embodiment provides a gypsum board cutting device, including a frame 10, a cutter 20, a first driving mechanism 30 and a cleaning device.

[0075] The frame 10 is arranged on the assembly line, and the cutter 20 is arranged on the frame 10 so as to be vertically movable. The cutter 20 is used to cut the gypsum board on the assembly line. The first driving mechanism 30 is used to drive the cutter 20 to move. The first driving mechanism 30 can be a hydraulic cylinder, which is arranged on the frame 10, and the output end of the hydraulic cylinder is connected to the upper end of the cutter 20. The cleaning device is used to clean the lower ends of both sides of the cutter 20.

[0076] In this embodiment, the cutter 20 moves up and down to cut the gypsum board on the assembly line, and the cleaning device cleans the contact position between the lower end of the cutter 20 and the gypsum board from both sides of the cutter 20 to prevent the gypsum slurry from adhering to the cutter 20, thereby preventing the gypsum slurry adhered and accumulated on the cutter 20 from adhering to the gypsum board when contacting the cut of the gypsum board when the cutter 20 is cutting the gypsum board, thereby reducing the generation of gypsum board waste.

[0077] In one embodiment, the cleaning device includes two cleaning mechanisms 40 ; the two cleaning mechanisms 40 are symmetrically arranged on both sides of the cutter 20 .

[0078] The cleaning mechanism 40 includes a support frame 41 , a second driving mechanism 43 and a cleaning column 44 .

[0079] The second driving mechanism 43 can drive the support frame 41 to move closer to or away from the lower end of the cutter 20, the second driving mechanism 43 can drive the support frame 41 to rotate, and the second driving mechanism 43 can also lock the support frame 41. Three cleaning columns 44 are provided, and the three cleaning columns 44 are parallel to each other, and the three cleaning columns 44 are all connected to the support frame 41. The axis of the cleaning column 44 is parallel to the rotation center line of the support frame 41; the axial direction of the cleaning column 44 is parallel to the cutting edge direction of the cutter 20; each cleaning column 44 can be against the lower end of the cutter 20 after rotation. The cleaning column 44 can be made of sponge material.

[0080] In practice, it is found that ordinary cleaning members, such as sponge cleaning members, are used to wipe off the gypsum slurry adhered to the cutter 20 after being abutted against the lower end of the cutter 20. After a while, the gypsum slurry adheres to the cleaning member, and the cleaning effect of the cleaning member on the cutter 20 will decrease, requiring the cleaning member to be replaced more frequently.

[0081] In this embodiment, the second driving mechanism 43 drives the support frame 41 to approach the cutter 20, and the cleaning column 44 on the support frame 41 abuts against the lower end of the cutter 20, and then moves upward to clean the cutter 20. Since the second driving mechanism 43 can drive the support frame 41 to rotate, the three cleaning columns 44 can be replaced in sequence during the cleaning process of the cutter 20, and the three cleaning columns 44 are replaced together after the gypsum slurry is adhered to them, so the replacement frequency is reduced.

[0082] In one embodiment, two second driving mechanisms 43 are provided; the two second driving structures are symmetrically arranged on the outer sides of the two ends of the support frame 41; the frame 10 includes two symmetrically arranged support seats 11; the support seat 11 corresponds to the second driving mechanism 43 on the same side.

[0083] The second driving mechanism 43 includes a slider 431 , a driving rod 432 and a motor 433 .

[0084] The slider 431 is slidably disposed on the support seat 11. Specifically, the support seat 11 is generally C-shaped as a whole, and the slider 431 slides in the support seat 11. The slider 431 can slide close to or away from the cutter 20, and a first hole 431a is provided on the slider 431. One end of the driving rod 432 passes through the first hole 431a, and the driving rod 432 is threadedly connected to the first hole 431a. The motor 433 is connected to the support seat 11, and the output end of the motor 433 is coaxially connected to the driving rod 432; the support frame 41 is connected to the slider 431.

[0085] In this embodiment, the motors 433 of the two second driving mechanisms 43 drive the driving rod 432 to rotate, driving the two sliders 431 to slide closer to or away from the cutter 20, so that the support frame 41 together with the cleaning column 44 on the support frame 41 moves closer to or away from the cutter 20.

[0086] In one embodiment, the support frame 41 includes a support rod 42, a second hole 431b is formed on the slider 431, and two ends of the support rod 42 respectively pass through the second holes 431b on the same side. The ends of the support rod 42 are rotatably connected to the second holes 431b.

[0087] The second driving mechanism 43 further includes a first gear 434 and a locking disk 435 .

[0088] The first gear 434 is coaxially sleeved on the end of the support rod 42, and a missing tooth on the first gear 434 forms a missing groove 434a, which is usually formed by a missing tooth of the first gear 434. The locking disc 435 is connected to the slider 431, and the outer wall of the locking disc 435 abuts against both sides of the mouth of the missing groove 434a.

[0089] In this embodiment, the outer wall of the locking disk 435 abuts against both sides of the mouth of the missing groove 434a, so that the first gear 434 cannot rotate, and the support rod 42 cannot rotate, thereby achieving locking of the support frame 41 together with the cleaning column 44.

[0090] In one embodiment, three missing grooves 434 a are provided on the first gear 434 ; the three missing grooves 434 a are evenly distributed circumferentially around the axis of the first gear 434 .

[0091] The locking disc 435 is rotatably connected to the slider 431; the locking disc 435 rotates with the help of the movement of the slider 431. A plurality of meshing grooves 435a extending along the axial direction are provided on the outer wall of the locking disc 435. The plurality of meshing grooves 435a can mesh with the gear teeth between two adjacent missing grooves 434a on the first gear 434, and the number of the meshing grooves 435a is the same as the number of the gear teeth between two adjacent missing grooves 434a on the first gear 434.

[0092] The second driving mechanism 43 further includes a docking ring 436 , docking teeth 437 and a trigger assembly 438 .

[0093] The docking ring 436 is coaxially connected to the end of the first gear 434. Three docking teeth 437 are provided, and the docking teeth 437 are connected to the outer wall of the docking ring 436. The three docking teeth 437 correspond to the three missing grooves 434a. The trigger assembly 438 can complete the multiple meshing grooves 435a, and the trigger assembly 438 can drive the docking teeth 437 to rotate around the axis of the first gear 434 after abutting against the docking teeth 437.

[0094] In this embodiment, when the trigger assembly 438 completes the meshing groove 435a, the outer peripheral wall of the locking disk 435 is a circumferential wall, so that the locking disk 435 can lock the first gear 434, so that the first gear 434 cannot rotate. Once the trigger assembly 438 no longer completes the meshing groove 435a, the meshing groove 435a on the rotating locking disk 435 moves to the gear teeth of the first gear 434, and the trigger assembly 438 drives the docking tooth 437 to move, so that the first gear 434 starts to rotate. At this time, the gear teeth on the first gear 434 mesh with the meshing groove 435a, thereby rotating the support rod 42. Since there are three missing grooves 434a on the first gear 434 and they are evenly distributed circumferentially on the first gear 434, after the first gear 434 is driven by the meshing groove 435a to rotate 120 degrees, the gear teeth on the first gear 434 disengage from the meshing groove 435a on the locking disk 435; then, the outer peripheral surface of the locking disk 435 cooperates with the missing groove 434a on the first gear 434 again to lock the first gear 434, so that the support frame 41 maintains the angle unchanged.

[0095] In one embodiment, a square third hole 435b is provided on the locking disc 435, and a penetrating fourth hole 431c is provided on the slider 431. A clearance groove 435c is provided on the side of the locking disc 435 away from the slider 431, and a clearance hole 435d is provided on the side of the locking disc 435 away from the slider 431, and the clearance hole 435d is located on one side of the engagement groove 435a. The bottom of the clearance groove 435c is connected with a plurality of engagement grooves 435a and the clearance hole 435d. Specifically, the mouth of the clearance hole 435d is located at the bottom of the clearance groove 435c, and the open end of one side of the engagement groove 435a is located at the bottom of the clearance groove 435c.

[0096] The trigger assembly 438 includes a connecting cylinder 438a, a square rod 438b, a connecting piece 438c, a trigger column 438d and a plurality of complementary columns 438e.

[0097] One end of the connecting tube 438a is coaxially connected to the inner wall of the fourth hole 431c, and the other end of the connecting tube 438a is coaxially connected to the locking disc 435; specifically, a bearing is connected to the outer sleeve of one end of the connecting tube 438a, and the bearing is fixedly connected to the inner wall of the fourth hole 431c. One end of the square rod 438b can be slidably inserted into the third hole 435b, and the square rod 438b slides in the third hole 435b. Specifically, the square rod 438b can be driven by a driving structure to achieve its sliding in the third hole 435b. The connecting member 438c is connected to the end of the square rod 438b, and the connecting member 438c can be embedded in the clearance groove 435c as the square rod 438b slides. One end of the trigger column 438d is connected to the connecting member 438c, and the other end of the trigger column 438d is slidably inserted into the clearance hole 435d, and can be against the docking tooth 437. One end of the complement column 438e is connected to the connecting member 438c, and the other end of the complement column 438e can be slidably inserted into the corresponding engagement groove 435a.

[0098] In this embodiment, when the slider 431 moves on the support seat 11 and approaches or moves away from the cutter 20, the locking disc 435 rotates. When the square rod 438b slides toward the middle of the support rod 42, the connecting member 438c drives the trigger column 438d to insert into the clearance hole 435d, the completion column 438e is inserted into the engagement groove 435a, and the connecting member 438c is embedded in the clearance groove 435c. At this time, the locking disc 435 is a cylinder, and the locking disc 435 locks the first gear 434. When the square rod 438b slides away from the middle of the support rod 42, the square rod 438b slides out of the third hole 435b, the connecting piece 438c slides out of the clearance groove 435c, the trigger rod slides out of the clearance hole 435d, and the completion column 438e slides out of the engagement groove 435a. Then, during the rotation of the locking disk 435, the trigger rod abuts against the docking tooth 437 on the first gear 434, driving the first gear 434 to rotate, and the gear teeth on the first gear 434 engage with the engagement groove 435a, thereby causing the first gear 434 to rotate 120 degrees.

[0099] In one embodiment, the second driving mechanism 43 further includes a driving rack 45 and a second gear 46 .

[0100] The driving rack 45 is disposed on the support seat 11 and is disposed along the axis of the driving rod 432. The second gear 46 is sleeved outside the connecting tube 438a and meshes with the driving rack 45.

[0101] In this embodiment, as the slider 431 slides on the support seat 11, the slider 431 is located on one side of the driving rack 45, and the second gear 46 rotates as the slider 431 slides, thereby driving the connecting tube 438a and the locking disk 435 to rotate.

[0102] In one embodiment, three fifth holes 421 are respectively formed at both ends of the support rod 42 , and there are six fifth holes 421 in total.

[0103] The support frame 41 further includes a connecting rod 47 and a support shaft 50 .

[0104] Six connecting rods 47 are provided, and one end of each connecting rod 47 slides through the corresponding fifth hole 421. Two limiting rings 48 are sleeved on each connecting rod 47, and the two limiting rings 48 are located on both sides of the support rod 42. Two first springs 49 are sleeved on each connecting rod 47, and the two first springs 49 are located on both sides of the support rod 42.

[0105] Three support shafts 50 are provided, and the two ends of the support shafts 50 are respectively connected to the ends of the corresponding connecting rods 47, and the support shafts 50 are parallel to the support rods 42. The cleaning column 44 is coaxially sleeved on the corresponding support shaft 50 through an opening; among the three connecting rods 47 at one end of the support rod 42, the angle between two adjacent connecting rods 47 is 60 degrees; the two ends of the first spring 49 are respectively connected to the corresponding limit ring 48 and the support rod 42.

[0106] In this embodiment, when the slider 431 moves close to the cutter 20, the cleaning columns 44 on both sides of the cutter 20 approach each other and rest against the cutter 20. Due to the presence of the first spring 49, the cleaning columns 44 and the cutter 20 can be tightly pressed against each other, thereby achieving a better cleaning effect.

[0107] In one embodiment, both ends of the support rod 42 are provided with a matching disk 51; the matching disk 51 is slidably sleeved on the outside of the support rod 42 through an opening; the matching disk 51 is located between the connecting rod 47 and the slider 431; the side of the matching disk 51 facing the connecting rod 47 is a conical surface; the side of the matching disk 51 away from the connecting rod 47 can be abutted against the square rod 438b; each of the connecting rods 47 is connected to a supporting rod 52 of different lengths; the end of the supporting rod 52 away from the connecting rod 47 can be abutted against the conical surface of the matching disk 51;

[0108] The second driving mechanism 43 also includes a reset plate 439 extending axially along the driving rod 432; the reset plate 439 includes a first portion 439a close to the motor 433 and a second portion 439b away from the motor 433; the distance between the first portion 439a and the driving rod 432 is smaller than the distance between the second portion 439b and the driving rod 432; the first portion 439a facing the driving rod 432 and the second portion 439b facing the driving rod 432 are inclined transitions; the reset plate 439 abuts against the end of the square rod 438b away from the driving block. The matching disk 51 and the reset plate 439 are respectively located on both sides of the slider 431, and the matching disk 51 and the reset plate 439 can cooperate with the moving trend of the slider 431 to make the square rod 438b slide back and forth in the square hole.

[0109] In this embodiment, the motor 433 pushes the slider 431 to slide on the support seat 11 through the driving rod 432. When there is no need to switch the cleaning column 44, when the slider 431 is close to the cutter 20, the cleaning columns 44 on both sides of the cutter 20 rest against the cutter 20, and the cutter 20 moves vertically to achieve its own cleaning, and then the slider 431 retreats to prepare for the next cleaning of the cutter 20.

[0110] When one cleaning column 44 is dirty and the support column needs to be switched, in the process of the slider 431 approaching the cutter 20, the cleaning columns 44 on both sides of the cutter 20 approach each other to clean the cutter 20; then the slider 431 further approaches the cutter 20, and the cleaning column 44 abutting against the cutter 20 drives the connecting rod 47 to slide in the fifth hole 421, and the abutting rod 52 connected to the connecting rod 47 approaches the axis of the support rod 42. At this time, the end of the moving abutting rod 52 moves on the conical surface of the matching disk 51, thereby pushing the matching disk 51 to slide on the support rod 42 and approach the slider 431, and then the square rod 438b is pushed out from the square hole toward the reset plate 439. At this time, the end of the square rod 438b is close to the second part 439b, and the square rod 438b drives the connecting piece 438c, the trigger column 438d and the complementary column 438e to move, thereby exposing the meshing groove 435a. When the slider 431 moves back away from the cutter 20 , the locking disc 435 rotates while following the rear side of the slider 431 , and the trigger column 438 d abuts against the docking tooth 437 to drive the first gear 434 to rotate, thereby realizing the rotation of the support frame 41 by 120 degrees and the switching of the cleaning column 44 .

[0111] In one embodiment, the support seat 11 is tilted so that the slider 431 is tilted relative to the assembly line when sliding. The cleaning mechanism 40 includes a cleaning tank 53; both ends of the cleaning tank 53 are respectively connected to the corresponding support seat 11; the cleaning tank 53 has a cleaning slope. The cross section of the cleaning tank 53 is V-shaped. A plurality of strip protrusions 54 are arranged on the cleaning slope; the strip protrusions 54 can contact with the corresponding cleaning columns 44; when the slider 431 moves away from the cutter 20, the cleaning column 44 moves along the cleaning slope to the bottom of the cleaning tank 53.

[0112] In this embodiment, when the slider 431 slides toward or away from the cutter 20, there is always a cleaning column 44 in the cleaning groove 53, and as the slider 431 slides, the cleaning column 44 reciprocates at the bottom of the cleaning groove 53 and on the strip protrusion 54, and the cleaning column 44 can rotate on the support shaft 50, so that the cleaning column 44 is cleaned in the cleaning groove 53. In addition, when the cleaning column 44 passes through the strip protrusion 54, the water in the cleaning groove 53 absorbed by the cleaning column 44 is squeezed out, so that the water on the cleaning column 44 will not be brought to the cutter 20 and affect the gypsum board. Moreover, the device is provided with three cleaning columns 44. When the cleaning columns 44 are switched, one of the cleaning columns 44 has been suspended in the air for a period of time, so that the switched cleaning column 44 has less water in it and will not bring excess water to the cutter 20.
