Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, and in particular to a braking conveying device in a drying machine layer. Background Art

[0002] As a dryer special drying equipment for gypsum board, chain transmission is indispensable in the drying section. The chain will wear and break after long-term operation, causing failure of the dryer, and then the drive chain of the faulty layer needs to be repaired.

[0003] In order to repair the transmission chain of the faulty layer, the prior art usually requires stopping the entire dryer to inspect the transmission chain.

[0004] In the prior art, if the entire dryer is shut down for maintenance due to a failure of a transmission chain, a large number of gypsum boards will be over-fired due to the shutdown, resulting in the production of defective products. Summary of the invention

[0005] To this end, the present invention provides a braking conveying device in a dryer layer to solve the technical problem that when a transmission chain of a layer of a dryer fails in the prior art, the entire dryer needs to be shut down for maintenance.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] A brake-type conveying device in a dryer layer, comprising a transition roller arranged at the entrance and exit of each layer of the dryer, a main drive sprocket being installed at the end of the transition roller, and the main drive sprocket being capable of driving the transition roller to rotate;

[0008] A fixed wheel is installed at the end of the transition roller away from the main transmission sprocket, and a driven sprocket is clamped on the side of the fixed wheel. The driven sprocket drives the transmission roller in the corresponding layer of the dryer to rotate through the transmission chain;

[0009] The driven sprocket is provided with an axis groove, and a sliding sleeve shaft is installed in the axis groove, and the driven sprocket can slide on the sliding sleeve shaft and can rotate around the sliding sleeve shaft;

[0010] A shift fork is arranged on the side of the driven sprocket, and the shift fork can be shifted to adjust the position of the driven sprocket on the sliding sleeve shaft, and the driven sprocket can be separated from the fixed wheel when being shifted.

[0011] Furthermore, a first sliding surface is provided on one side of the driven sprocket, and a second sliding surface is provided on one side of the fixed wheel;

[0012] When the driven sprocket and the fixed wheel are close to each other, the first sliding surface and the second sliding surface are engaged.

[0013] Furthermore, a fixing seat is provided on one side of the sliding sleeve shaft, the end of the shift fork is hinged on the fixing seat, and the shift fork can rotate around the fixing seat and shift the driven sprocket to translate axially along the sliding sleeve shaft.

[0014] Furthermore, the shift fork is a Y-shaped shift fork.

[0015] Furthermore, the driven sprocket is connected with a shaft sleeve, and the shaft sleeve is sleeved outside the sliding sleeve shaft;

[0016] The shaft sleeve is provided with a groove for the end of the shift fork to be placed in.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention utilizes a shift fork to shift the shaft sleeve to axially translate outwardly along the axis of the sliding sleeve, driving the driven sprocket away from the fixed wheel, so that the driven sprocket is separated from the main transmission speed and remains stationary. When the transmission chain is repaired, the shaft sleeve is shifted to drive the driven sprocket to axially translate inwardly close to the fixed wheel and engage with the sliding surface thereof. The transmission chain on the driven sprocket can be synchronously transmitted with the transmission chain on the main transmission sprocket, thereby achieving braking of the faulty layer and repairing of the transmission chain without affecting the operation of the entire dryer.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, the present invention provides a braking conveying device in a drying machine layer, comprising a transition roller 1 arranged at the entrance and exit of each layer of the drying machine, a main transmission sprocket 5 is installed at the end of the transition roller 1, and the main transmission sprocket 5 can drive the transition roller 1 to rotate;

[0025] A fixed wheel 2 is installed at the end of the transition roller 1 away from the main transmission sprocket 5, and a driven sprocket 3 is clamped on the side of the fixed wheel 2. The driven sprocket 3 drives the transmission roller in the corresponding layer of the dryer to rotate through the transmission chain;

[0026] An axis groove is formed in the driven sprocket 3, and a sliding sleeve shaft 4 is installed in the axis groove. The driven sprocket 3 can slide on the sliding sleeve shaft 4 and can rotate around the sliding sleeve shaft 4.

[0027] A shift fork 6 is provided on the side of the driven sprocket 3 , and the shift fork 6 can be moved to adjust the position of the driven sprocket 3 on the sliding sleeve shaft 4 , and the driven sprocket 3 can be separated from the fixed wheel 2 when being moved.

[0028] In order to facilitate the control of the engagement between the fixed wheel 2 and the driven sprocket 3, a first sliding surface is provided on one side of the driven sprocket 3, and a second sliding surface is provided on one side of the fixed wheel 2;

[0029] When the driven sprocket 3 and the fixed wheel 2 are close to each other, the first sliding surface and the second sliding surface are engaged.

[0030] In the present invention, the shift fork 6 is designed to drive the driven sprocket 3 to translate axially along the sleeve shaft 4. Therefore, the present invention makes the following design: a fixed seat 7 is provided on one side of the sleeve shaft 4, the end of the shift fork 6 is hinged on the fixed seat 7, and the shift fork 6 can rotate around the fixed seat 7;

[0031] Since the shift fork 6 can rotate around the fixed seat 7 , shifting the shift fork 6 can drive the shaft sleeve and the driven sprocket 3 to translate along the axial direction of the transition roller 1 as a whole.

[0032] In order to keep the shaft sleeve moving smoothly when the fork 6 is used to shift the shaft sleeve, the shaft sleeve needs to be evenly stressed. Therefore, the fork 6 is designed to be Y-shaped, and grooves are symmetrically opened on the shaft sleeve for the plug end of the fork 6 to be placed.

[0033] In order to enable the shaft sleeve to slide axially along the sleeve shaft 4 , the inner wall diameter of the shaft sleeve is designed to be larger than the diameter of the sleeve shaft 4 .

[0034] In the present invention, the main transmission sprocket 5 is externally connected to a driving device, and the driving device drives the transition roller 1 to rotate by driving the main transmission sprocket 5 to rotate;

[0035] The shift fork 6 in the present invention is used to shift and adjust the position of the transmission chain in the fault layer to cut off the transmission relationship between the transition roller 1 in the fault layer and other transmission rollers in the dryer.

[0036] When the transmission chain on the driven sprocket 3 fails, the maintenance personnel can drive the shaft sleeve and the driven sprocket 3 to move axially outward along the sliding sleeve shaft 4 by shifting the shift fork 6, so that the driven sprocket 3 is out of the engagement state with the fixed wheel 2. In this way, the speed at which the driven sprocket 3 is out of the main transmission remains stationary, and the maintenance personnel can repair the transmission chain on the driven sprocket 3;

[0037] When the drive chain on the driven sprocket 3 is repaired, the maintenance personnel also shifts the shift fork 6 to drive the sleeve and the driven sprocket 3 to move axially inward along the sleeve shaft 4, so that the sliding section of the driven sprocket 3 is engaged with the sliding section of the fixed wheel 2 to form a whole, and the drive chain on the driven sprocket 3 can keep up with the rotation speed of the main drive sprocket 5 to perform normal conveying work.

[0038] In summary, in order to solve the problem that the entire dryer needs to be shut down for maintenance when a transmission chain of a certain layer of the dryer fails in the prior art, the present invention designs a braking transmission device in the dryer layer, which drives the driven sprocket 3 away from the fixed wheel 2 by using the shift fork 6 to shift the shaft sleeve 4 axially outward, so that the driven sprocket 3 is separated from the main transmission speed and remains stationary. When the transmission chain is repaired, the shaft sleeve is moved to drive the driven sprocket 3 to shift axially inward to close to the fixed wheel 2 and engage with its sliding surface, so that the transmission chain on the driven sprocket 3 can be synchronously driven with the transmission chain on the main transmission sprocket 5. The dryer does not need to be stopped during the maintenance process, so the maintenance of the faulty transmission chain is completed without affecting the normal operation of the dryer.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
