Description

Technical Field

[0001] The present application relates to the field of glue degassing equipment, and in particular to a degassing transmission device. Background Art

[0002] At present, latex or rubber products are common in industrial production and daily life. The glue raw materials used to produce and process such products are prone to produce bubbles inside the glue during the processing. Due to the high viscosity of the glue, it is difficult for the bubbles to escape from the glue on their own. In order to ensure the quality and appearance of the product, such products need to be degassed during the processing of the glue raw materials.

[0003] Related technologies usually use centrifugal degassing, which uses centrifugal force to make the glue with a larger specific gravity sink to the bottom, thereby forcing the bubbles with a lighter specific gravity to escape from the surface of the glue. The specific implementation method is usually to store the glue in a cylindrical mixing barrel, and drive the mixing barrel to rotate around its own axis through a motor. The motor and the mixing barrel are transmitted through a gear set. In order to improve the degassing effect, the rotation axis of the mixing barrel is usually set at an angle.

[0004] Regarding the above-mentioned related technologies, in order to facilitate installation, the rotation axis of the output end of the motor is usually set horizontally or vertically. Therefore, there is a certain angle between the rotation axis of the inclined mixing barrel and the rotation axis of the output end of the motor, which increases the complexity of the transmission structure of the gear set used for transmission between the motor and the mixing barrel, and increases the difficulty of installation and disassembly of the equipment. Summary of the invention

[0005] In order to simplify the transmission structure for driving the inclined stirring barrel to rotate, the present application provides a degassing transmission device.

[0006] The present application provides a degassing transmission device, which adopts the following technical solution:

[0007] A degassing transmission device comprises a mounting frame, a driving assembly arranged on the mounting frame, a driving gear and a transmission assembly, wherein the transmission assembly comprises a driving belt, a pressure wheel and a driven gear used to be coaxially connected to an inclined mixing barrel, wherein the driving gear, the driven gear and the pressure wheel are rotatably arranged on the mounting frame; the driving assembly is used to drive the driving gear to rotate, and the rotation axis of the driving gear is arranged vertically; the rotation axis of the driving gear is coplanar with the rotation axis of the driven gear, and an angle is arranged between the rotation axis of the driven gear and the rotation axis of the driving gear, and the plane where the rotation axis of the driving gear and the rotation axis of the driven gear are located together is a transmission reference plane;

[0008] One side surface of the transmission belt is provided with teeth for meshing with the driving gear and the driven gear, the transmission belt is simultaneously wound around and meshed between the driving gear and the driven gear, two groups of pressure wheels are provided, the two groups of pressure wheels are provided between the driving gear and the driven gear, the two groups of pressure wheels are respectively provided on both sides of the transmission reference plane, an angle is provided between the rotation axis of the pressure wheel and the transmission reference plane, and the peripheral side surfaces of the two groups of pressure wheels are simultaneously rolled and pressed against the transmission belt;

[0009] The pressure wheel is used to bend the transmission belt at the pressure wheel, and to make the straight line where the transmission direction of the transmission belt close to the driving gear is perpendicular to the rotation axis of the driving gear, and to make the straight line where the transmission direction of the transmission belt close to the driven gear is perpendicular to the rotation axis of the driven gear.

[0010] By adopting the above technical scheme, the driving gear drives the driven gear to rotate through the transmission belt. Due to the material characteristics of the transmission belt, the pressure wheel inclined relative to the transmission reference plane bends the transmission belt in the middle during the rolling and tight contact with the transmission belt, so that the transmission direction of the transmission belt near the driving gear is perpendicular to the rotation axis of the driving gear, and the straight line where the transmission direction of the transmission belt near the driven gear is perpendicular to the rotation axis of the driven gear, so as to avoid the transmission belt being worn or even the transmission belt being separated from the driving gear and the driven gear due to the inconsistency between the transmission direction of the transmission belt and the rotation direction of the driving gear and the driven gear during the transmission process as much as possible; and the pressure wheel can rotate with the transmission belt during the transmission of the transmission belt, and is not easy to affect the normal movement of the transmission belt; compared with the transmission through the gear set, the transmission structure for driving the inclined mixing barrel to rotate is greatly simplified by the transmission through the transmission belt, and the weight and cost of the transmission structure are greatly reduced.

[0011] The transmission assembly further comprises two sets of active tensioning wheels and two sets of driven tensioning wheels rotatably arranged on the mounting frame, the two sets of active tensioning wheels are respectively located on both sides of the active gear, and the two sets of driven tensioning wheels are respectively located on both sides of the driven gear; the side surface of the transmission belt with teeth is the outer peripheral surface of the transmission belt, the two sets of active tensioning wheels roll and press against the inner peripheral surface of the transmission belt, the outer peripheral surface of the transmission belt is meshed with the side of the driving gear close to the driven gear, and the two sets of active tensioning wheels are used to press the outer peripheral surface of the transmission belt against the side of the driving gear close to the driven gear; the two sets of driven tensioning wheels roll and press against the inner peripheral surface of the transmission belt, the outer peripheral surface of the transmission belt is meshed with the side of the driven gear close to the driving gear, and the two sets of driven tensioning wheels are used to press the outer peripheral surface of the transmission belt against the side of the driven gear close to the driving gear.

[0012] By adopting the above technical solution, two sets of active tension wheels press the outer circumference of the transmission belt tightly and mesh with the active gear, and the active gear drives the transmission belt to move; two sets of driven tension wheels press the outer circumference of the transmission belt tightly and mesh with the driven gear, and the moving transmission belt drives the driven gear to rotate; in this transmission mode, when the transmission belt is transmitting, the teeth are exposed on the outer circumference of the transmission belt, and personnel can check the teeth of the transmission belt at any time to detect wear in time.

[0013] Optionally, the transmission belt is located between two groups of pressure wheels, and one end of the pressure wheel away from the mounting frame is inclined toward the direction close to the transmission reference plane. The peripheral surface of the pressure wheel is provided with teeth, and one end of the peripheral surface of the pressure wheel close to the transmission reference plane is pressed against and meshed with the outer peripheral surface of the transmission belt.

[0014] By adopting the above technical scheme, the pressure wheel presses the transmission belt towards the transmission reference plane while bending the transmission belt, and presses the transmission belt against the driven tensioning wheel and the active tensioning wheel while tensioning the transmission belt, thereby improving the stability of the transmission belt during transmission; since the teeth of the transmission belt are arranged on the outer peripheral surface of the transmission belt, the pressure wheel meshes with the outer peripheral surface of the transmission belt while pressing the transmission belt, thereby improving the tightness of the transmission between the transmission belt and the pressure wheel, making it difficult for the transmission belt to separate from the pressure wheel during transmission.

[0015] Optionally, the mounting frame includes a base platform, an adjustment platform arranged on the base platform, a driven mounting platform and a support platform, the driving gear is arranged on the base platform, the pressure wheel is arranged on the adjustment platform, the driven gear and the driven tensioning wheel are rotatably connected to the driven mounting platform, an installation space is arranged between the driven mounting platform and the support platform, the driven gear is located in the installation space, and one end of the driven gear away from the driven mounting platform is rotatably connected to the support platform; the support platform is used for rotatably mounting a mixing barrel and for the mixing barrel to be coaxially connected to the driven gear.

[0016] By adopting the above technical solution, the mixing barrel filled with glue is installed on the support platform, and the support platform transmits the weight of the mixing barrel to the two mounting plates, so that the driven gear connected to the driving mixing barrel coaxially does not need to directly bear the weight of the mixing barrel, thereby reducing the load of the entire transmission component during the transmission process and improving the overall service life of the transmission component.

[0017] Optionally, two ends of the driven tension wheel are detachably and rotatably connected to the driven mounting platform and the supporting platform.

[0018] By adopting the above technical solution, since the transmission belt is pressed against and meshed with the outer peripheral surface of the transmission belt on the side of the peripheral surface of the driven gear close to the driving gear through two driven tensioning wheels, it is only necessary to remove the driven tensioning wheel from the driven mounting platform and the support platform, and then the transmission belt can be removed from between the driving gear and the driven gear. Compared with the transmission method in which the transmission belt is sleeved between the driving gear and the driven gear, when disassembling and installing the transmission belt, there is no need to remove the support platform and the mixing barrel arranged on the support platform as a whole, which facilitates the installation and disassembly of the transmission belt.

[0019] Optionally, the transmission components are provided in two groups, the driving gear is provided between the two groups of the transmission components, and the peripheral surface of the driving gear close to both ends of the two groups of the transmission components is meshed with the two transmission belts at the same time.

[0020] By adopting the above technical solution and a transmission method in which the outer peripheral surface of the transmission belt is meshed with the driving gear, the driving gear can be tightly meshed with two sets of belts at the same time, thereby realizing transmission through one driving gear cooperating with two transmission belts at the same time, thereby realizing one driving gear driving two driven gears to rotate, and then realizing the degassing operation of two mixing barrels at the same time, thereby improving the efficiency of degassing the glue solution in this application.

[0021] Optionally, a connecting member is provided between two adjacent active tensioning wheels respectively located in the two groups of the transmission components, and the connecting member is provided at one end of the active tensioning wheel away from the base platform, and both ends of the connecting member are respectively detachably rotatably connected to the two active tensioning wheels.

[0022] By adopting the above technical solution, the connecting piece connects the two sets of transmission components, thereby improving the overall stability of the two sets of transmission components during the transmission process; at the same time, the connecting piece limits the transmission belt from slipping off the active tensioning wheel in the direction away from the base platform. The transmission belt can be removed from the active tensioning wheel by removing the connecting piece, thereby facilitating the disassembly of the transmission belt.

[0023] Optionally, the angle between the rotation axis of the driven gear and the rotation axis of the driving gear ranges from 10 to 35 degrees, and the angle between the rotation axis of the pressure wheel and the transmission reference plane is three quarters of the angle between the rotation axis of the driven gear and the rotation axis of the driving gear.

[0024] By adopting the above technical scheme, 10-35 degrees is the commonly used inclination angle range of the mixing barrel during the degassing of the glue liquid. When the inclination angle is within this range, the degassing efficiency of the glue liquid is ensured while the glue liquid is not easy to overflow from the mixing barrel; and the inclination angle of the rotation axis of the pressure wheel is set to three quarters of the inclination angle of the driven gear, so that the pressure wheel can correct the deviation of the transmission belt near the driving gear and the driven gear while not causing the transmission belt to twist too much near the driving gear and the driven gear.

[0032] Reference Figure 1 and Figure 2 The mixing barrels 5 are arranged on both sides of the driving gear 3, the rotation axes of the two mixing barrels 5 are coplanar with the rotation axis of the driving gear 3, and the two mixing barrels 5 are symmetrically arranged relative to the rotation axis of the driving gear, and the plane where the rotation axes of the two mixing barrels 5 and the rotation axis of the driving gear 3 are located together is the transmission reference plane; the angle between the rotation axis of the mixing barrel 5 and the rotation axis of the driving gear 3 is in the range of 10-35 degrees. In the present embodiment, the angle between the rotation axis of the mixing barrel 5 and the rotation axis of the driving gear 3 is 25 degrees.

[0033] Reference Figure 1 and Figure 2 The mounting frame 1 includes a base platform 11, an adjustment platform 12, a driven mounting platform 13 and a support platform 14. The base platform 11 is composed of a mounting block 111 and two mounting plates 112. The driving component 2 is arranged at the bottom of the mounting block 111, and the driving gear 3 is rotatably arranged on the mounting block 111. The two mounting plates 112 are fixed to two sides of the mounting block 111 away from each other by bolts. The two mounting plates 112 are parallel to each other and symmetrically arranged relative to the mounting block 111.

[0034] Reference Figure 2 and Figure 3The transmission assembly 4 includes a transmission belt 41, a driven gear 42, two pressure wheels 43, two active tension wheels 44 and two driven tension wheels 45; the active tension wheels 44 in the two sets of transmission assemblies 4 are rotatably set on the base platform 11, two adjustment platforms 12 are provided, and the two ends of the adjustment platform 12 are respectively fixedly connected with two mounting plates 112 by bolts, and the pressure wheels 43 in the two sets of transmission assemblies 4 are respectively rotatably set on the two adjustment platforms 12; two driven mounting platforms 13 and supporting platforms 14 are each provided, and the fixed installation method of the driven mounting platforms 13 and the supporting platforms 14 is the same as the fixed installation method of the adjustment platform 12; the two adjustment platforms 12 are symmetrically arranged on both sides of the mounting block 111, The two driven mounting platforms 13 are symmetrically arranged on both sides of the mounting block 111 and the two adjustment platforms 12 are located between the two driven mounting platforms 13; the support platform 14 is located above the adjustment platform 12, the support platform 14 is arranged parallel to the driven mounting platform 13 and an installation space 15 is arranged between the support platform 14 and the driven mounting platform 13, the bottom of the mixing barrel 5 is rotatably arranged on the support platform 14, the driven gear 42 and the driven tensioning wheel 45 in the two sets of transmission components 4 are arranged in the installation space 15, the two ends of the driven gear 42 are rotatably connected to the driven mounting platform 13 and the support platform 14 respectively, the driven gear 42 and the bottom of the mixing barrel 5 are connected through the bearings and the reduction gear group inside the support platform 14 and are coaxially driven.

[0035] The mixing barrel 5 is installed on the support platform 14, and the support platform 14 transmits the weight of the mixing barrel 5 to the two mounting plates 112, so that the driven gear 42 coaxially connected to the driving mixing barrel 5 does not need to directly bear the weight of the mixing barrel 5, thereby reducing the load of the transmission component 4 as a whole during the transmission process and improving the service life of the transmission component 4 as a whole.

[0036] Reference Figure 2 and Figure 3 In one set of transmission components 4: the outer circumferential surface of the transmission belt 41 in the illustrated state is provided with teeth (not shown in the figure), the active tensioning wheel 44 and the driven tensioning wheel 45 are connected to the inner circumferential surface of the transmission belt 41, the two active tensioning wheels 44 press the outer circumferential surface of the transmission belt 41 and mesh with the side surface of the driving gear 3 close to the driven gear 42, the two driven tensioning wheels 45 press the outer circumferential surface of the transmission belt 41 and mesh with the side surface of the driven gear 42 close to the driving gear 3, the transmission belt 41 in the other set of transmission components 4 is pressed and meshed with the other side of the side surface of the driven gear 42, and the transmission belt 41 is in a tensioned state.

[0037] The two pressure wheels 43 are symmetrically arranged on both sides of the transmission reference plane, the rotation axes of the two pressure wheels 43 are coplanar, and the plane where the two pressure wheels 43 are located is perpendicular to the transmission reference plane; the two pressure wheels 43 are inclined toward each other from one end away from the adjustment platform 12, and the angle between the rotation axis of the pressure wheel 43 and the rotation axis of the driving gear 3 is 19 degrees, which is approximately three quarters of the angle reading value between the rotation axis of the driven gear 42 and the rotation axis of the driving gear 3.

[0038] The pressure wheel 43 is provided with teeth on the circumferential surface, and the transmission belt 41 is located between the two pressure wheels 43. The two ends of the circumferential surfaces of the two pressure wheels 43 that are close to each other are simultaneously pressed and meshed with the outer circumferential surface of the transmission belt 41. The pressure wheel 43 bends the transmission belt 41, and makes the transmission direction of the transmission belt 41 close to the driving gear 3 perpendicular to the rotation axis of the driving gear 3, and makes the transmission direction of the transmission belt 41 close to the driven gear 42 perpendicular to the rotation axis of the driven gear 42. Try to avoid the transmission belt 41 from being worn or even disengaged from the driving gear 3 and the driven gear 42 during the transmission process due to the inconsistency between the transmission direction of the transmission belt 41 and the rotation directions of the driving gear 3 and the driven gear 42. Compared with transmission through a gear set, transmission through the transmission belt 41 greatly simplifies the transmission structure for driving the inclined mixing barrel 5 to rotate, and the weight and cost of the transmission structure are greatly reduced.

[0039] The pressure wheel 43 presses the transmission belt 41 toward the transmission reference plane while bending the transmission belt 41, and presses the transmission belt 41 against the driven tensioning wheel 45 and the driving tensioning wheel 44 while tensioning the transmission belt 41, thereby improving the stability of the transmission belt 41 during transmission; since the teeth of the transmission belt 41 are arranged on the outer peripheral surface of the transmission belt 41, the pressure wheel 43 meshes with the outer peripheral surface of the transmission belt 41 while pressing the transmission belt 41, thereby improving the tightness of the transmission between the transmission belt 41 and the pressure wheel 43, making it difficult for the transmission belt 41 to separate from the pressure wheel 43 during the transmission process; the setting of the inclination angle of the pressure wheel 43 makes it difficult for the pressure wheel 43 to correct the deviation of the transmission belt 41 near the driving gear 3 and the driven gear 42, while preventing the transmission belt 41 from being twisted too much near the driving gear 3 and the driven gear 42.

[0040] Reference Figure 2The adjustment platform 12 includes a platform body 121 and two sliding blocks 122. The two pressure wheels 43 are rotatably connected to the two sliding blocks 122 respectively. Two waist-shaped holes are respectively opened at both ends of the platform body 121. The waist-shaped holes are arranged in parallel and the straight line where the length direction of the waist-shaped holes is perpendicular to the transmission reference plane. The sliding block 122 is fixed to the platform body 121 by two bolts (not shown in the figure) respectively penetrating the two waist-shaped holes. The bolts are loosened so that the bolts can slide in the waist-shaped holes, and the distance between the two pressure wheels 43 can be adjusted, thereby realizing the adjustment of the tension of the transmission belt 41 through the two pressure wheels 43.

[0041] Reference Figure 2 and Figure 3 , two active tensioning wheels 44 in one group of transmission components 4 are respectively located on both sides of the driving gear 3, and a connecting member 6 is provided between two adjacent active tensioning wheels 44 in the two groups of transmission components 4, and the connecting member 6 is a rectangular block. The active tensioning wheel 44 is sleeved on a rotating shaft vertically fixed on the base platform 11, and the active tensioning wheel 44 rotates around the transmission shaft through a bearing. The connecting member 6 is located at one end of the active tensioning wheel 44 away from the base platform 11, and the two ends of the connecting member 6 are respectively fixed to the two rotating shafts at the two active tensioning wheels 44 by bolts, so that the active tensioning wheel 44 can rotate relative to the connecting member 6; the connecting member 6 connects the two groups of transmission components 4, thereby improving the overall stability of the two groups of transmission components 4 during the transmission process; at the same time, the connecting member 6 serves to limit the transmission belt 41 from slipping off the active tensioning wheel 44 in the direction away from the base platform 11.

[0042] Reference Figure 3 and Figure 4The driven tensioning wheel 45 includes an adjusting rod 451 and a wheel body 452 sleeved on the adjusting rod 451, and the wheel body 452 rotates around the adjusting rod 451 through a bearing; two first guide grooves 131 are provided on the surface of the side opposite to the driven mounting platform 13 and the support platform 14, and the straight line where the length direction of the first guide groove 131 is parallel to the transmission guide surface and perpendicular to the rotation axis of the driven gear 42, and the two first guide grooves 131 are symmetrically arranged on both sides of the driven gear 42, and the side wall of the first guide groove 131 away from the driving gear 3 is penetrated and forms a first plug interface 132; two second guide grooves 141 are provided on the surface of the side opposite to the driven mounting platform 13, and the straight line where the length direction of the second guide groove 141 is parallel to the transmission guide surface and perpendicular to the rotation axis of the driven gear 42, The two second guide grooves 141 are symmetrically arranged on both sides of the driven gear 42, and the side wall of the second guide groove 141 away from the driving gear 3 is penetrated and formed with a second plug-in interface 142; the notch of the first guide groove 131 is arranged opposite to the notch of the second guide groove 141, and the two ends of the adjusting rod 451 can be correspondingly inserted into the first guide groove 131 and the second guide groove 141 arranged opposite to the notch at the same time, and one end of the adjusting rod 451 located in the first guide groove 131 is fixed to the groove wall on the side of the first guide groove 131 opposite to the first plug-in interface 132 by bolts, and the one end of the adjusting rod 451 located in the second guide groove 141 is fixed to the groove wall on the side of the second guide groove 141 opposite to the second plug-in interface 142, so as to fix the driven tensioning wheel 45 between the driven mounting platform 13 and the support platform 14.

[0043] Reference Figure 3 and Figure 4 When the transmission belt 41 needs to be replaced, first remove the connecting piece 6 from the active tensioning wheel 44, remove the transmission belt 41 from the active tensioning wheel 44, so that the transmission belt 41 is loose, and then unscrew the bolts used to fix the driven tensioning wheel 45, and slide the driven tensioning wheel 45 out of the first guide groove 131 and the second guide groove 141 in the direction away from the driving gear 3. Since the outer peripheral surface of the transmission belt 41 is meshed with the two sides of the driven gear 42 and the driving gear 3 that are close to each other, the transmission belt 41 can be directly removed from between the driving gear 3 and the driven gear 42 without disassembling the support platform 14, which facilitates the disassembly and installation of the transmission belt 41.

[0044] The implementation principle of a degassing transmission device in the embodiment of the present application is as follows: the driving gear 3 drives the driven gear 42 to rotate through the transmission belt 41. Due to the material characteristics of the transmission belt 41, the pressure wheel 43, which is inclined relative to the transmission reference plane, bends the transmission belt 41 in the middle during the rolling and pressing process with the transmission belt 41, so that the transmission direction of the transmission belt 41 near the driving gear 3 is perpendicular to the rotation axis of the driving gear 3, and the straight line where the transmission direction of the transmission belt 41 near the driven gear 42 is located is perpendicular to the rotation axis of the driven gear 42, so as to avoid the transmission belt 41 from being worn or even separated from the driving gear 3 and the driven gear 42 due to the inconsistency between the transmission direction of the transmission belt 41 and the rotation direction of the driving gear 3 and the driven gear 42 during the transmission process; and the pressure wheel 43 can rotate with the transmission belt 41 during the transmission process of the transmission belt 41, and is not easy to affect the normal movement of the transmission belt 41; compared with the transmission through the gear set, the transmission structure of driving the inclined mixing barrel 5 to rotate is greatly simplified by the transmission through the transmission belt 41, and the weight and cost of the transmission structure are greatly reduced.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
