DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1 andFigure 3 As shown, the utility model is a continuous environmentally friendly and efficient alcoholysis machine, including a chassis 6, the chassis 6 is a rectangular parallelepiped structure, the outer wall of the chassis 6 uses insulation cotton to insulate the inside, the insulation cotton material includes but is not limited to glass wool, rock wool, aluminum silicate wool, and the outer surface of the chassis 6 is covered with a stainless steel mirror panel. The inner wall of the chassis 6 is provided with a coil 5, one end of the coil 5 is connected to an external steam pipe, and the other end is connected to an external condensate pipe. The temperature of the internal environment of the chassis 6 can be increased by steam heating, which is convenient for rapid temperature adjustment, so that the equipment can adapt to sudden changes in winter temperature.

[0030] The surface of the chassis 6 is also provided with a plurality of observation windows for observing the material condition inside the chassis 6 , and the top of the chassis 6 is provided with a plurality of inspection ports for convenient inspection of the components inside the chassis 6 .

[0031] Specifically, a feed port 61 is provided at the top of one end of the chassis 6, and a feed port 62 and a liquid outlet 63 are respectively provided at the side and bottom of the other end. A rebound material collecting slot is provided below the liquid outlet 63. Alcoholysis material can be put into the chassis 6 through the feed port 61, and the material is discharged through the feed port 62 after the reaction in the chassis 6. The liquid outlet 63 discharges the chemical liquid after the material reaction and the powdered rebound material in the equipment connected to the feed port 62. The chemical liquid and the powdered rebound material discharged from the liquid outlet 63 are recovered through the rebound material collecting slot.

[0032] A transmission device 1 is arranged on the side of one end of the chassis 6, and the transmission device 1 includes a motor reducer assembly 11, and the motor reducer assembly 11 includes a reducer. The reducer adopts a direct-connected frequency conversion structure to achieve stepless speed change. The reducer is fixed with an external bracket, and the output end of the reducer is connected to a sprocket mechanism 12. The sprocket mechanism 12 includes a driving sprocket, a chain and a passive sprocket. The sprocket mechanism 12 is connected to a driving wheel 13 through a driving shaft, and the sprocket mechanism 12 and the driving wheel 13 form a closed transmission structure through a belt.

[0033] The rotating shaft at the center of the driving wheel 12 is rotatably installed with the conveyor frame 2 through a bearing. The conveyor frame 2 is installed on the box base of the chassis 6, and the conveyor frame 2 and the chassis 6 are fixed by a fixed pressure block. The driving wheel 13 is connected to the conveyor belt 4. The conveyor belt 4 adopts an integral endless belt. Compared with the chain used in the prior art, the conveyor belt 4 without rivet joints has no hidden danger of rivet falling off.

[0034] It can be understood that due to the limited speed ratio of the reducer, by selecting the diameter specifications of the driving sprocket and the passive sprocket in the sprocket mechanism 12, further deceleration can be achieved on the basis of transmission, thereby reducing the rotation speed of the driving wheel 13, and then reducing the conveying speed of the conveyor belt 4 to meet the device's requirements for the material conveying speed.

[0035] See also Figure 2 ,Figure 4 As shown, the conveyor belt 4 is connected to the tension adjusting device 3. The tension adjusting device 3 includes a passive roller 36. The passive roller 36 is drivingly connected to the driving wheel 13 through the conveyor belt 4. After the conveyor belt 4 is tensioned by the driving wheel 13 and the passive roller 36, it is driven to run by friction. When the conveyor belt 4 passes through the conveyor frame 2, a number of support inclined rollers provided on both sides of the conveyor frame 2 recess the two sides of the conveyor belt 4 into a U shape (not shown in the figure). The inclination angle of the support inclined rollers is adjustable, so that the products on the conveyor belt 4 are not easily dropped, and at the same time, the appearance structure and geometric dimensions of the products after forming can meet the requirements.

[0036] The tension adjusting device 3 further includes a sliding bearing track 31. The sliding bearing track 31 is fixed to the conveyor frame 2. The sliding bearing track 31 is slidably connected to a sliding bearing 34. The sliding bearing 34 is rotatably connected to the passive roller 36. A guide block 33 is fixedly installed on one side of the sliding bearing 34. The guide block 33 is threadedly connected to a traction screw 32. The traction screw 32 is fixed to the conveyor frame 2 through a fixing nut 35.

[0037] In this embodiment, by rotating the traction screw 32, the guide block 33 can be pulled, thereby driving the sliding bearing 34 to move along the sliding bearing track 31. The sliding bearing 34 drives the passive roller 36 to move to adjust the tension of the conveyor belt 4 and keep the conveyor belt 4 in a tensioned state. When the conveyor belt 4 gradually relaxes, the sliding bearing 34 is moved in a direction away from the traction screw 32 by adjusting the traction screw 32. When the sliding bearing 34 moves to the maximum position (the maximum position can be calculated according to the material of the conveyor belt 4, which is a common technique for those skilled in the art, so no more details will be given here), if the conveyor belt 4 still cannot be tensioned, the wear degree of the conveyor belt 4 reaches the level that needs to be replaced. Through the tension adjusting device 3, not only can the conveyor belt 4 be tensioned to operate normally, but also the relaxation and wear conditions of the conveyor belt 4 can be intuitively reflected, which is convenient for timely maintenance and prevents the production from being affected due to equipment damage.

[0038] Please refer to Figure 6 As shown, the conveyor frame 2 is connected to the wrap angle control device 8. The wrap angle control device 8 includes an adjusting roller 81. The adjusting roller 81 is bolted with a slider 82. The slider 82 can slide axially along the conveyor frame 2. The slider 82 is connected to an adjusting screw 83. The adjusting screw 83 is installed on the conveyor frame 2. By rotating the adjusting screw 83, the slider 82 is driven to move, and then the adjusting roller 81 is driven to move. Since the adjusting roller 81 is in close contact with the conveyor belt 4, the moving distance of the adjusting roller 81 can adjust the wrap angle between the driving wheel 13 and the conveyor belt 4, so that the friction force between the adjusting roller 81 and the conveyor belt 4 changes to adjust the contact area between the conveyor belt 4 and the driving wheel 13, thereby improving the transmission efficiency and reducing slip, and significantly enhancing the stability and transmission efficiency of the transmission device 1.

[0039] Please refer to Figure 5 As shown, the conveying frame 2 is connected to the clamping and guiding device 7. The clamping and guiding device 7 includes a pressing roller 72. The pressing roller 72 is connected to one end of the connecting rod through a support bearing seat, and the other end of the connecting rod is hinged to the vertical rod on the conveying frame 2.

[0040] Furthermore, a cylinder 71 is fixedly installed on the conveying frame 2. The air source used by the cylinder 71 is an external compressed air interface of 0.4 MPa. The air source pipe is connected to the cylinder 71 through a valve and a pneumatic reversing valve. The telescopic end of the cylinder 71 slides on the connecting rod. The height of the pressing roller 72 can be adjusted through the cylinder 71. The pressing roller 72 and the passive roller 36 form a clamping structure, so that the material located below the pressing roller 72 on the conveyor belt 4 can be clamped by the clamping structure, which is convenient for shaping.

[0041] Please refer to Figure 1 、 Figure 5 As shown, in this embodiment, several guiding rollers 73 are arranged on one side of the pressing roller 72, and two left and right baffles 74 are arranged above the guiding rollers 73. The baffles 74 are in an eight-shaped state. The shaped material products are conveyed by the rotating guiding rollers 73, and the baffles 74 guide the material products, so that the final products can be discharged smoothly, continuously and accurately from the discharge port 62.

[0042] During use, the motor 11 operates and transmits kinetic energy to the reducer. The reducer drives the driving shaft to rotate. The driving shaft of the reducer drives the sprocket mechanism 12 to rotate, thereby driving the driving wheel 13 to rotate. The material is injected onto the conveyor belt 4 through the feed port 61 of the machine case 6 and is conveyed by the conveyor belt 4 to the discharge port 62. During the conveying process by the conveyor belt 4, the material will undergo a series of chemical reactions and then reach the end of the passive roller 36. After being shaped by the clamping and guiding device 7, it is discharged from the discharge port 62. The chemical liquid discharged from the liquid outlet 63 and the powdered rebounding material are recovered through the rebounding material collection tank, while the conveyor belt 4 circulates between the driving wheel 13 and the passive roller 36 to achieve continuous operation.

[0043] The inventor found that in the existing chain drive system, the chain needs to be adjusted and replaced frequently after wear, and in addition, the conveyor belt often breaks during operation due to insufficient tensile strength of the conveyor belt support, too large conveyor belt screw holes, insufficient bolt pressing force, deviation of the parallelism and tooth alignment of the main drive shaft sprocket, bending deformation of the main skeleton, and poor organic cooperation between the conveyor belt, alcoholysis machine support and conveyor belt bolts, etc., resulting in shutdown, which is difficult to meet the needs of continuous production and reduces production efficiency. Moreover, when repairing the chain drive system, the maintenance labor and material costs are relatively high, the labor intensity is large, the time is long, the labor protection requirements for the operator are relatively high, the operation is inconvenient, and there are relatively large potential production safety hazards.

[0044] In this application, the conveyor belt 4 is directly driven by the driving wheel 13 and the driven roller 36, replacing the chain drive in the prior art. The chain drive system has a relatively high maintenance frequency. The structure formed by the conveyor belt 4, the driving wheel 13 and the driven roller 36 adopted in this application is simple and compact, and can reduce the replacement frequency of the conveyor belt 4 and the material and labor costs required for mechanical maintenance.

[0045] It can be understood that since this equipment does not adopt a chain drive system, the inspection and maintenance time can be reduced, thereby effectively improving the production efficiency. It can also avoid the chips and oil stains caused by chain wear and lubricating oil addition from adhering to the product, further improving the product quality.

[0046] In addition, by directly driving the driving wheel 13 and the driven roller 36, the risk of deflagration caused by mechanical friction and ignition is reduced, thereby improving the safety performance of the equipment and realizing a safe, environmentally friendly, continuous and efficient production mode for chemical production.

[0047] Working principle: When in use, the motor 11 works and transmits kinetic energy to the speed reducer. The speed reducer drives the driving shaft to rotate, the driving shaft drives the sprocket mechanism 12 to rotate, the sprocket mechanism 12 drives the driving wheel 13 to rotate. Materials are injected onto the conveyor belt 4 through the feed inlet 61 of the machine case 6 and are conveyed by the conveyor belt 4 to the discharge outlet 62. During the conveying process by the conveyor belt 4, the materials will undergo a series of chemical reactions and reach the end of the driven roller 36. After being shaped by the clamping and guiding device 7, they are discharged from the discharge outlet 62. The conveyor belt 4 runs cyclically between the driving wheel 13 and the driven roller 36 to achieve continuous operation.

[0048] The above has described in detail an embodiment of the present utility model, but the content described is only a preferred embodiment of the present utility model and cannot be considered as used to limit the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the claims of the present utility model.
