Description

TECHNICAL FIELD

[0001] A smooth transition device and a plate discharging machine belong to the technical field of gypsum board equipment transportation. BACKGROUND

[0002] With the needs of economic development, the demand for gypsum board in the construction industry is increasing, and gypsum board is widely used in various buildings such as residential buildings, office buildings, stores, hotels and industrial plants. In order to improve the production efficiency of gypsum board, after drying, the gypsum board is transported from the outlet of the drying machine to the inclined roller way of the plate discharging machine, and gradually changes from multiple layers to one layer. The upper layer of dried gypsum board enters the next layer through the inclined roller way.

[0003] When the gypsum board is transported to the lower layer transportation device by the upper layer transportation device with a height difference, as the gypsum board is transported, the front end of the gypsum board is in a suspended state. When the center of gravity of the gypsum board passes the end of the upper layer transportation device, the front end of the gypsum board falls onto the lower layer transportation device, and the front end of the gypsum board and the end of the upper layer transportation device serve as a fulcrum to lift the rear end of the entire gypsum board, forming a head lifting phenomenon, until the end of the gypsum board falls onto the lower layer transportation device. The head lifting phenomenon of the end of the gypsum board not only causes certain damage to the frame and sensor of the upper layer transportation device, but also causes certain damage to the gypsum board itself when it falls from the upper layer transportation device to the lower layer transportation device.

[0004] In order to improve the transportation quality of the gypsum board, in the prior art such as patent CN113895928A, a smooth transition device is provided between the two transportation devices. The smooth transition device is fixedly arranged between the two transportation devices, and the smooth transition device reduces the collision of the gypsum board by means of the inclined transition plate. However, the transition device in the patent cannot adapt to the transportation angle of the gypsum board due to its fixed arrangement, and the front end of the gypsum board still directly falls from the suspended state to the smooth transition device or the lower layer transportation device. The problem of gypsum board loss caused by the height difference is not effectively solved, and the head lifting of the end of the gypsum board is also not effectively solved. In other patents, multiple adjusting devices are arranged on the lower side of the transition plate. The structure is complex, and the adjusting devices are not sensitive after a long time of use, so the smooth transition function cannot be achieved, and the gypsum board is still damaged to a certain extent.

PREFERRED EMBODIMENT

[0021] Figs. 1-2 It is the best embodiment of the utility model, and the following will be combined with the attached Figs. 1-2 The utility model is further explained.

[0022] Refer to Figs. 1-2 The plate discharging machine of the utility model includes a plurality of layer transport devices and a stable transition device arranged between two layer transport devices with height difference, in order to facilitate description, the upper layer transport device and the lower layer transport device are used instead of the two layer transport devices, and it is not clear which two layer transport devices are, and the stable transition device is arranged at the end of the upper layer transport device.

[0023] The utility model discloses a conveying device for conveniently conveying gypsum board, which is provided with a certain inclination angle, and the original inclination angle of the smooth transition device is adjusted by adjusting the adjusting plate 12 arranged between the upper conveying device and the lower conveying device. Specifically, the two ends of the belt roller 11 are connected to the cross beams of the upper conveying device and the lower conveying device through bearings, one end of the rack 10 is rotatably connected to the belt roller 11, and the other end is connected to the cross beam of the lower conveying device through the adjusting plate 12. The adjusting plate 12 is provided with a plurality of adjusting plate adjusting holes 1201 and is fixed to the rack 10 through bolts. The adjusting plate adjusting holes 1201 are fixed at different heights, so that the rack 10 has a certain inclination angle.

[0024] The smooth transition device comprises a rotating shaft 1, a following plate 2, a rotating sleeve 3, a crank arm 4 and a counterweight 5. The rotating shaft 1 is arranged in parallel to the belt roller 11 of the upper conveying device and has a height lower than that of the belt roller 11. The rotating shaft 1 is rotatably arranged on the rack 10 through two bearings. The triangular rotating sleeve 3 is fixedly arranged on the rotating shaft 1, and one of the oblique sides of the rotating sleeve 3 is arranged in parallel to the inclination angle of the upper conveying device. A plurality of following plates 2 are arranged on the oblique side of the rotating sleeve 3 in the conveying direction at intervals. A fixing plate is arranged between the lower side of each following plate 2 and the rotating sleeve 3. The length of the fixing plate is less than that of the following plate 2. The following plate 2 is arranged in parallel to the inclination angle of the upper conveying device, and the end thereof is lower than the front end and faces the lower conveying device.

[0025] The crank arm 4 is arranged in the opposite direction to the following plate 2 at the end of the rotating shaft 1 and is coaxially arranged with the rotating shaft 1. The extension direction of the arm is opposite to the conveying direction. A plurality of crank arm adjusting holes 401 are arranged in parallel on the crank arm 4, and the counterweight 5 is fixed in the crank arm adjusting holes 401. The arrangement of the counterweight 5 ensures that the initial state of the following plate 2 is always parallel to the inclination angle of the upper conveying device. When the following plate 2 is subjected to the change of gravity caused by the forward movement of the gypsum board, the balance state changes. The gravity on one side of the following plate 2 passes through the length of the rotating shaft 1 to form a moment, and the gravity of the gypsum board itself forms an applied force, so as to overcome the gravity of the counterweight 5 and the distance between the counterweight 5 and the crank arm 4 to form a moment. When the moments are equal, the balance is maintained, and when the moments are not equal, the gypsum board is inclined. The greater the gravity on one side of the gypsum board, the greater the inclination angle. By adjusting the position of the counterweight 5 on the crank arm 4, the moment on one side of the counterweight 5 is changed, so as to adapt to the gypsum board with different lengths.

[0026] The end of the crank arm 4 is also provided with a limiting device to limit the angle of rotation of the crank arm 4, the limiting device comprises an upper limiting device and a lower limiting device, the upper limiting device and the lower limiting device are arranged on the side wall of the upper conveying device, and one end of the crank arm 4 is arranged between the upper limiting device and the lower limiting device. The upper limiting device comprises an L-shaped upper mounting plate 6 and a circular upper limiting block 7, the vertical section of the upper mounting plate 6 is fixed on the side wall by bolts, the parallel section is arranged vertically to the side wall, and the upper limiting block 7 is arranged on the lower side of the parallel section; the lower limiting device comprises an L-shaped lower mounting plate 8 and a circular lower limiting block 9, and the lower limiting device is arranged upside down on the rack 10, the vertical section of the lower mounting plate 8 is fixed on the side wall, the parallel section is arranged on the upper side of the vertical section, and the lower limiting block 9 is arranged on the upper side of the parallel section.

[0027] The cantilever end of the crank arm 4 is arranged between the upper limiting block 7 and the lower limiting block 9, the crank arm 4 is always placed on the lower limiting block 9 due to the weight of the counterweight 5 when not subjected to the pressure of the gypsum board, and when subjected to the pressure of the gypsum board, the shaft 1 rotates along the bearing to drive the cantilever end of the crank arm 4 to be raised, and the maximum height of the raised crank arm 4 is limited by the upper limiting block 7 and the lower limiting block 9 which are made of soft rubber.

[0028] Working process:

[0029] During the conveying process, when the front end of the gypsum board passes through the shaft 1 and is conveyed forward along the inclined plate 2, the inclination angle of the inclined plate 2 is consistent with the inclination angle of the upper conveying device, so that the front end of the gypsum board is smoothly transferred to the lower conveying device.

[0030] The gypsum board continues to advance, and when the center of gravity of the gypsum board passes through the shaft 1, the pressure borne by the inclined plate 2 is greater than the weight of the counterweight 5 at this time, so that the counterweight 5 is completely lifted and limited by the upper limiting block 7, and the front end of the inclined plate 2 contacts the lower conveying device, so that the end of the gypsum board can be smoothly transferred to the lower conveying device.

[0031] After the gypsum board completely separates from the inclined plate 2, the shaft 1 returns to the initial position due to the weight of the counterweight 5, and the cycle is repeated.

[0032] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to obtain equivalent embodiments. However, any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belongs to the protection scope of the technical scheme of the present application.
