[0017] The present invention provides a mask transmission device for mask processing, which has the following beneficial effects:

[0018] 1. The present invention sets a feeding mechanism, and the feeding box and the inlet mask fall toward the center and rotate on the bearing sheet, so that the sheet-shaped packaged masks put into the inlet mask and the feeding box can be shaken out with the swinging movement, and the masks concentrated in the inlet mask and the feeding box can be prevented from being squeezed and unable to be fed due to the friction between each other. Through the swinging, the masks in the lower feeding box are subjected to the centrifugal force of the swinging of the feeding box, and the masks are accelerated to be thrown downward, thereby improving the feeding speed and feeding stability.

[0019] 2. The present invention sets a feeding mechanism. When the bearing sheet and the feeding box swing, the ventilation slots opened on one side of the feeding box allow the external air to circulate with the inside of the feeding box when the feeding box swings, so that the sheet-shaped packaged masks inside the feeding box are pushed by the air to vibrate, further reducing the congestion and blockage problems caused by the feeding of masks, improving the smoothness of the feeding of masks, and the feeding box is connected inside and outside to avoid the problem of internal negative pressure causing the mask to be difficult to fall.

[0020] 3. The present invention sets a feeding mechanism. When the feeding box hits the next billiard ball during its swinging, it will continue to be pushed by the next billiard ball, thereby realizing the reciprocating swinging effect of the feeding box. When the feeding box contacts the billiard ball during its swinging, it will collide with the billiard ball and generate vibration. The vibration generated by the collision between the billiard ball and the feeding box during the swinging will shake off a large number of sheet-shaped packaged masks flowing through the feeding box, thereby further improving the feeding speed of the masks and reducing the problem of jamming and blockage.

[0021] 4. The present invention sets a feeding mechanism so that when the feeding box swings, the sliding block will descend on the sliding bar to push the masks in the feeding box, push the masks that are entangled together apart and break them up, and apply downward pressure. When the feeding box contacts the billiard ball again and is slowly pushed by the billiard ball, the feeding box no longer swings with inertia. At this time, the sliding block is no longer affected by the centrifugal force and is pulled back to its original position by the elastic force of the elastic rope, thereby achieving a reciprocating working state in which the sliding block continuously performs a cyclic working process of rising and falling on the sliding bar, thereby completing the work process of lifting and breaking up and pressing down the masks inside the feeding box, thereby improving the efficiency of breaking up and feeding the masks.

[0022] 5. The present invention sets a separation mechanism, and the sheet-shaped packaged masks falling through the discharge box will contact the triangular block outside the rotating shaft and be separated by the tip of the top of the triangular block and the separation plates on both sides of the triangular block, so that the masks can be separated as much as possible when they fall onto the conveyor, reducing the accumulation of masks and making the masks as flat as possible for subsequent picking and other work. In addition, due to the presence of the counterweight block at the bottom of the triangular block, the tip of the top of the triangular block remains stable and always points upward. The separation plate can also be kept stable by the fixed column and will not be affected by the rotation of the rotating shaft, thereby maintaining the stable separation effect of the triangular block and the separation plate on the masks.

[0023] 6. The present invention sets a separation mechanism so that the triangular block can perform a slight back and forth deflection vibration, and utilizes the elasticity of the spring to make the triangular block also have a certain up and down vibration range. The triangular block also drives the separation plate to vibrate synchronously through the fixed column. Then, under the vibration of the triangular block, the mask packaging sheet that falls on the triangular block and the separation plate will accelerate its fall on the surface of the triangular block and the separation plate as it vibrates, reducing the problem of the mask packaging sheet being difficult to fall due to the friction between the triangular block and the separation plate, thereby improving the work efficiency of mask separation and flattening.

DETAILED DESCRIPTION

[0039] Example 1: Please refer to Figure 1-4 , the present invention provides a technical solution: a mask transmission device for mask processing, comprising a bracket 2, a conveyor 1 is fixedly connected to the top of the bracket 2, and a feeding mechanism 3 is arranged on the top of the conveyor 1;

[0040] The unloading mechanism 3 comprises:

[0041] The fixing rod 301 is an inverted L-shaped rod structure. The bottom end of the fixing rod 301 is fixedly connected to the top of the conveyor 1. The other end of the fixing rod 301 is fixedly connected to a bearing sheet 302. One side of the bearing sheet 302 is rotatably connected to a material discharge box 304 and an inlet mask 303. The fixing rod 301 is used to support the material discharge box 304 and the inlet mask 303. The inlet mask 303 and the material discharge box 304 are used to collect and discharge masks in a centralized manner.

[0042] The ventilation slot 305 is a long strip slot-shaped structure. The ventilation slot 305 is provided on both sides of the material box 304. The material box 304 is connected to the outside through the ventilation slot 305. There are two fixed rods 301. The outer wall of the fixed rod 301 on the left side is fixedly connected to the motor 306. The ventilation slot 305 is used to make the material box 304 communicate with the inside and outside.

[0043] When in use, after the masks are packaged in a transparent bag in pieces, they are automatically received by the inlet cover 303, enter the inlet cover 303, and then enter the discharge box 304 below, and then fall evenly and concentratedly on the conveyor 1 through the discharge box 304, so that the conveyor 1 performs subsequent transmission work to complete the centralized collection and transmission of the masks after being packaged in pieces;

[0044] Example 2: Please refer to Figure 1-11On the basis of the first embodiment, the present invention provides a technical solution: the output end of the motor 306 is fixedly connected with a rotating shaft 307, the outer wall of the rotating shaft 307 is fixedly connected with a connecting sleeve 308, and the outer wall of the connecting sleeve 308 is fixedly connected with a connecting plate 309.

[0045] One end of the connecting plate 309 is fixedly connected with a billiard ball 310 , which is a spherical structure, and the inlet housing 303 is a hollow trapezoidal structure.

[0046] The inner wall of the material discharge box 304 is fixedly connected with a sliding bar 311 , the outer wall of the sliding bar 311 is slidably connected with a sliding block 312 , and the top of the sliding block 312 is fixedly connected with an elastic rope 313 .

[0047] One end of the elastic rope 313 is fixedly connected to a baffle 314, and one side of the baffle 314 is fixedly connected to one side of the inner wall of the unloading box 304;

[0048] During the transmission process, the motor 306 is started at the same time, and the motor 306 controls the rotation of the shaft 307. When the shaft 307 rotates, the connecting sleeve 308 and the connecting plate 309 of the outer wall are driven to rotate synchronously. When the connecting plate 309 rotates, the billiard ball 310 is driven to rotate. When the billiard ball 310 rotates, it will contact the upper material box 304 and be moved by the billiard ball 310. The material box 304 and the inlet cover 303 swing on one end of the fixed rod 301 through the bearing sheet 302. When one of the billiard balls 310 moves the material box 304 and detaches from the material box 304, The discharge box 304 and the inlet cover 303 will swing and rotate on the bearing sheet 302 as they fall toward the center, so that the sheet-shaped packaged masks put into the inlet cover 303 and the discharge box 304 can be shaken out with the swinging movement, and the masks concentrated in the inlet cover 303 and the discharge box 304 can be shaken out, so as to prevent the problem of being unable to discharge materials due to the friction between them. When swinging, the masks in the discharge box 304 below are subjected to the centrifugal force of the swinging of the discharge box 304, so that the masks are accelerated to be thrown downward, thereby improving the discharge speed and the discharge stability;

[0049] When the bearing sheet 302 and the material box 304 are swinging, the ventilation slots 305 provided on one side of the material box 304 allow the external air to circulate with the inside of the material box 304 when the material box 304 is swinging, so that the sheet-shaped packaged masks inside the material box 304 are pushed by the air to vibrate, further reducing the congestion and blockage problem when the masks are unloaded, improving the smoothness of the unloading of the masks, and the inside and outside of the material box 304 are connected, avoiding the problem that the masks are difficult to fall due to the generation of internal negative pressure;

[0050] When the material box 304 hits the next billiard ball 310 during its swing, it will continue to be pushed by the next billiard ball 310, thereby realizing the reciprocating swinging action of the material box 304. When the material box 304 contacts the billiard ball 310 during its swing, it will collide with the billiard ball 310 and generate vibration. The vibration generated by the collision between the billiard ball 310 and the material box 304 during the swinging will shake off a large number of sheet-shaped packaged masks flowing through the material box 304, further improving the material discharge speed of the masks and reducing the jamming problem.

[0051] When the material box 304 is swung, since the center of the swinging circle is centered on the bearing plate 302, the sliding block 312 inside the material box 304 will be driven by the sliding bar 311 on the inner wall of the material box 304 to swing in a circle when the material box 304 is swung. When the sliding block 312 is swung, it will be affected by the centrifugal force because it is far away from the center of the bearing plate 302, and will slide down on the outer wall of the sliding bar 311, and pull the elastic rope 313 to deform it, so that when the material box 304 is swung, the sliding block 312 will move down on the sliding bar 311 to push the masks in the material box 304, and the masks will be entangled. The masks that are together are pushed apart and pressure is applied downwards. When the material box 304 contacts the billiard ball 310 again and is slowly pushed by the billiard ball 310, the material box 304 no longer swings with inertia. Then, the sliding block 312 is no longer subjected to the centrifugal force and is pulled back to its original position by the elastic force of the elastic rope 313. Thus, in this reciprocating working state, the sliding block 312 continuously performs a cyclic working process of rising and falling on the sliding bar 311, and then completes the work process of lifting and breaking up the masks inside the material box 304 and pressing and pushing them out, thereby improving the efficiency of breaking up and unloading the masks.

[0052] Example 3: Please refer to Figure 1-14 On the basis of the first and second embodiments, the present invention provides a technical solution: a separation mechanism 4 is provided on the outer wall of the rotating shaft 307 , and the separation mechanism 4 includes a fixing sleeve 401 , and the inner wall of the fixing sleeve 401 is fixedly connected to the outer wall of the rotating shaft 307 .

[0053] A magnetic groove 407 is provided on the outer wall of the fixing sleeve 401, and a lifting block 404 is slidably connected to the outer wall of the fixing sleeve 401. Triangular blocks 402 are slidably connected on both sides of the lifting block 404. A groove 403 is provided on the inner wall of the triangular block 402. The triangular block 402 is slidably connected to the outer wall of the lifting block 404 through the groove 403 on the inner wall.

[0054] A spring 405 is fixedly connected to the outer wall of the lifting block 404, one end of the spring 405 is fixedly connected to the inner wall of the groove 403, and fixed columns 408 are fixedly connected to both sides of the triangular block 402, and one end of the fixed column 408 is fixedly connected to a separation plate 409;

[0055] The sheet-shaped packaged masks falling from the discharge box 304 will contact the triangular block 402 outside the rotating shaft 307, and will be separated by the top tip of the triangular block 402 and the separation plates 409 on both sides of the triangular block 402, so that when the masks fall onto the conveyor 1, they are separated as much as possible, reducing the accumulation of masks and making the masks as flat as possible for subsequent picking and other work. In addition, due to the presence of the counterweight block 406 at the bottom of the triangular block 402, the top tip of the triangular block 402 is kept stable and always pointing upward. The separation plate 409 can also be kept stable by the fixed column 408 and will not be affected by the rotation of the rotating shaft 307, thereby maintaining the triangular block 402 and the separation plate 409 to always stably separate the masks.

[0056] During the rotation of the rotating shaft 307, the fixed sleeve 401 on the outer wall will be driven to rotate. The outer wall of the fixed sleeve 401 is provided with a magnetic groove 407. The magnetic groove 407 and the lifting block 404 slidably connected on the outer wall of the fixed sleeve 401 are magnets that attract each other. Therefore, during the rotation of the rotating shaft 307, the fixed sleeve 401 and the magnetic groove 407 will be driven to rotate synchronously. When the magnetic groove 407 rotates, it uses the magnetic attraction with the lifting block 404 to drive the lifting block 404 to deflect slightly. The lifting block 404 drives the triangular block 402 to deflect slightly on the inner wall of the groove 403. After the triangular block 402 is deflected, due to the existence of the counterweight block 406, the force of the counterweight block 406 returning to the positive position will overcome the magnetic attraction between the lifting block 404 and the rotating shaft 307, so that the rotating shaft 307 07 is separated from the magnetic attraction of the lifting block 404, then the triangular block 402 and the counterweight block 406 drive the lifting block 404 in the inner wall of the groove 403 to return to the normal position, so that the triangular block 402 performs a slight back and forth deflection vibration, and uses the elasticity of the spring 405 to make the triangular block 402 also have a certain range of up and down vibration, and the triangular block 402 also drives the separation plate 409 to vibrate synchronously through the fixed column 408, and then under the vibration of the triangular block 402, the mask packaging sheet that falls on the triangular block 402 and the separation plate 409 will accelerate the fall on the surface of the triangular block 402 and the separation plate 409 with its vibration, reducing the problem that the mask packaging sheet is difficult to fall due to the friction between the triangular block 402 and the separation plate 409, and improving the work efficiency of the mask separation and flattening. The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution and its inventive concept of the present invention, is equivalently replaced or changed, which should be covered within the protection scope of the present invention.
