Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for a foaming machine. Background Technology

[0002] Foaming machines, also known as foaming machines, originally used rotating impellers to create foam, which was then expanded by high-pressure air inflation. Foaming machines need to be used in conjunction with foaming agents. To facilitate the mixing of raw materials and foaming agents, a feeding device is often used to add the mixed raw materials. Since foaming machines need to be used in conjunction with foaming agents, an appropriate proportion of foaming agent needs to be added to the raw materials before foaming. Therefore, the feeding device also needs to process the raw materials for proportioning.

[0003] Chinese utility model patent CN220095298U discloses a feeding device for a foaming machine that facilitates proportioning and feeding. The device includes a feeding hopper, a feeding pipe fixedly connected to the bottom surface of the feeding hopper, a support frame fixedly connected to the top surface of the feeding hopper, a proportioning tank fixedly connected to the top surface of the support frame, graduation lines on the surface of the proportioning tank, a material injection pipe fixedly inserted into the top surface of the proportioning tank, and a material conveying pipe fixedly inserted into the bottom surface of the proportioning tank, with the material conveying pipe fixedly inserted into the feeding hopper.

[0004] The aforementioned foaming machine feeding device requires operators to constantly observe the readings on the scale on the mixing tank during the process of mixing raw materials and foaming agents to determine the height of the material descent, thereby ensuring the mixing ratio of raw materials and foaming agents. This is inconvenient to use and does not improve the efficiency of the device's mixing operation. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a feeding device for a foaming machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding device for a foaming machine, comprising a feeding tank and a discharge assembly disposed on the feeding tank for discharging the mixture in the feeding tank. The top of the feeding tank is fixed and connected to two sets of injection pipes. The top of the injection pipes is fixed and connected to a mixing tank. A sealing piston is slidably connected inside the mixing tank. The number of mixing tanks, the number of sealing pistons, and the number of injection pipes are all equal and their positions correspond one-to-one. The feeding tank is provided with a lifting mechanism for driving the two sets of sealing pistons to rise and fall synchronously. The injection pipes are provided with sealing assemblies for discharging material into the feeding tank through the injection pipes when the sealing pistons rise or remain stationary. The mixing tanks are provided with a feeding assembly for feeding the material.

[0007] By adopting the above technical solution, during the process of mixing raw materials and foaming agent, the lifting mechanism drives two sets of sealing pistons to descend synchronously. The two sets of sealing pistons simultaneously compress the air in the two sets of mixing tanks, increasing the pressure in the two sets of mixing tanks. The materials and foaming agent are discharged into the feeding tanks through the two sets of injection pipes respectively. Since the two sets of sealing pistons descend at the same speed, a one-to-one ratio of raw materials to foaming agent is achieved. Throughout the process, there is no need for operators to constantly observe the descent of materials in the mixing tanks, making operation more convenient and improving the efficiency of the mixing work of the device.

[0008] Furthermore, the lifting mechanism includes an installation assembly, which includes a mounting frame fixed to the top of the feeding tank, a driven column rotatably mounted on the mounting frame, and an active column rotatably mounted on the mounting frame. The lifting mechanism also includes a lifting assembly and a drive assembly for synchronous rotation of the driven column and the active column. The number of lifting assemblies is equal to the number of feeding tanks and their positions correspond one-to-one. Each lifting assembly includes a vertical rod that passes through the top of the feeding tank and is slidably connected. The lower end of the vertical rod is fixed to the top of the sealing piston. The lifting assembly also includes a connecting rod rotatably mounted on the vertical rod, a horizontal rod rotatably mounted on the connecting rod, and a turntable rotatably mounted on the end of the horizontal rod away from the connecting rod. The horizontal rod and the turntable are eccentrically arranged. One of the turntables is fixed to the driven column and coaxially arranged, and the other turntable is fixed to the active column and coaxially arranged.

[0009] By adopting the above technical solution, during the process of mixing raw materials and foaming agent, the driven component drives the driven column and the driving column to rotate synchronously for one revolution. This causes the two sets of turntables connected to the driven column and the driving column, the crossbars connected to the two sets of turntables, and the connecting rods connected to the two sets of crossbars to all rotate synchronously for one revolution. During this process, the connecting rod is first forced to lower the sealing piston and compress the air in the mixing tank. Finally, the vertical rod drives the sealing piston to rise and reset, thereby achieving the purpose of mixing raw materials and foaming agent. In addition, the amount of raw materials and foaming agent mixed each time can be controlled by controlling the rotation angle of the turntables, and the operation of the device can be adjusted according to specific needs.

[0010] Furthermore, the drive assembly includes a drive motor fixed on the mounting bracket, a drive gear fixedly sleeved on the drive motor, a driven gear fixedly sleeved on the drive column and meshing with the drive gear, a main synchronous pulley fixedly sleeved on the drive column, a driven synchronous pulley fixedly sleeved on the driven column, and a synchronous belt for connecting the main synchronous pulley and the driven synchronous pulley, wherein both the main synchronous pulley and the driven synchronous pulley mesh with the synchronous belt.

[0011] By adopting the above technical solution, after the drive motor works, it drives the drive gear to rotate, which causes the driven gear meshing with the drive gear, the drive column connected to the driven gear, and the main synchronous pulley connected to the drive column to rotate. Since the synchronous belt is used to connect the main synchronous pulley and the driven synchronous pulley, both the main synchronous pulley and the driven synchronous pulley mesh with the synchronous belt, thereby causing the driven column connected to the driven synchronous pulley to rotate, thus achieving the purpose of synchronous rotation of the two sets of turntables.

[0012] Furthermore, the sealing assembly includes a connecting plate fixed to the bottom of the injection tube, an mounting sleeve fixed to the lower end of the connecting plate, a slide rod inserted into and connected to the inner wall of the mounting sleeve, a spring fixed between the bottom of the slide rod and the inner bottom wall of the mounting sleeve, a sealing ball fixed to the upper end of the slide rod, and a sealing sleeve fixedly sleeved on the slide rod and slidably connected to the inner side wall of the mounting sleeve. The inner top wall of the injection tube is provided with a discharge through hole, and the distance between the discharge through hole and the axis of the injection tube gradually increases from top to bottom. The sealing ball abuts against the discharge through hole.

[0013] By adopting the above technical solution, during the descent of the sealing piston, the pressure inside the mixing tank increases, the sealing ball is subjected to force and descends, causing the sliding rod connected to the sealing ball and the sealing sleeve connected to the sliding rod to descend as well. The spring is subjected to force and gradually contracts until the sealing ball separates from the discharge hole. At this point, the material first flows into the injection pipe through the discharge hole, and finally flows into the feeding tank through the gap between the injection pipe, the mounting sleeve, and the connecting plate. When the sealing piston is stationary, the pressure inside the mixing tank gradually returns to its initial pressure due to the discharge of material. The spring gradually extends and resets, causing the sliding rod, sealing sleeve, and sealing ball to rise and reset until the sealing ball is pressed tightly against the discharge hole. This achieves the purpose of preventing material from flowing into the feeding tank through the injection pipe when the sealing piston is stationary or rising.

[0014] Furthermore, a sliding groove is provided through the turntable, and an adjustment assembly is provided on the turntable. The number of adjustment assemblies and the number of sliding grooves are equal to the number of turntables, and their positions correspond one-to-one. The adjustment assembly includes a slider that is slidably installed in the sliding groove and a threaded rod that is rotatably installed in the sliding groove and threadedly connected to the slider. The threaded rod passes through the top of the sliding groove and is rotatably connected. The crossbar is rotatably connected to the slider. The top of both sets of threaded rods is provided with an auxiliary groove.

[0015] By adopting the above technical solution, rotating the threaded rod causes the slider connected to the threaded rod, the horizontal bar connected to the slider, the connecting rod connected to the horizontal bar, the vertical bar connected to the connecting rod, and the sealing piston connected to the vertical bar to all rise and fall. This adjusts the distance between the slider and the axis of the turntable, as well as the height of the sealing piston inside the mixing tank. During the rotation of the turntable, the distance of the adjustable sealing piston's rise and fall is changed, thus controlling the amount of material discharged from the mixing tank into the feeding tank. By adjusting one set of sealing pistons, the ratio of material discharged from the two mixing tanks into the feeding tank can be changed, expanding the applicability of the device.

[0016] Furthermore, the feeding tank is equipped with a stirring assembly, which includes a stirring rod rotatably mounted on the top wall inside the feeding tank, stirring blades fixed on the stirring rod, and a stirring motor fixed to the top of the feeding tank and driving the stirring rod to rotate.

[0017] By adopting the above technical solution, during the process of raw materials and foaming agent entering the feeding tank, the stirring motor drives the stirring rod to rotate, which causes the stirring blades connected to the stirring rod to rotate and stir and mix the raw materials and foaming agent, thereby improving the mixing speed of raw materials and foaming agent.

[0018] Furthermore, an indicator block is fixed on the slider, and a scale line is provided on the side wall of the turntable near the indicator block.

[0019] By adopting the above technical solution, the setting of the indicator block and scale line facilitates the adjustment of the distance between the slider and the axis of the turntable.

[0020] Furthermore, the discharge assembly includes a discharge pipe fixed and connected to the bottom of the feeding tank and an electric valve disposed on the discharge pipe, and the feeding assembly includes a feed pipe fixed and connected to the bottom of the injection pipe and a solenoid valve disposed on the feed pipe.

[0021] By adopting the above technical solution, when the sealing piston descends to the lowest position, the solenoid valve is opened, and then the sealing piston rises. At this time, the pressure inside the mixing tank increases, and the material will be sucked into the mixing tank through the feed pipe for subsequent mixing of raw materials and foaming agent.

[0022] In summary, this utility model has the following beneficial effects: In this application, by setting up a feeding pipe, a mixing tank, a sealing piston and a lifting mechanism, the tedious operation of the staff constantly observing the descent height of the material in the mixing tank is eliminated, thus improving the efficiency of the device's mixing operation.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-5As shown in the figure, this application discloses a feeding device for a foaming machine, including a feeding tank 1, a discharging assembly 2, a feeding assembly 13, a lifting mechanism 6, a sealing assembly 7, a chute 9, and a stirring assembly 8. Two sets of injection pipes 3 are fixedly connected to the top of the feeding tank 1. Discharge holes are provided through the inner top wall of each injection pipe 3, and the distance between the discharge holes and the axis of the injection pipe 3 gradually increases from top to bottom. A mixing tank 4 is fixedly connected to the top of the injection pipe 3. A sealing piston 5 is slidably connected inside the mixing tank 4. The number of mixing tanks 4, the number of sealing pistons 5, and the number of injection pipes 3 are all equal, and their positions correspond one-to-one. The discharging assembly 2 is disposed on the feeding tank 1 and is used to discharge the mixture inside the feeding tank 1. The discharging assembly 2 includes a discharging pipe 21 and an electric valve 22. The discharging pipe 21 is fixedly connected to the bottom of the feeding tank 1, and the electric valve 22 is disposed on the discharging pipe 21. The feeding assembly 13 includes a feed pipe 131 and a solenoid valve 132. The feed pipe 131 is fixed and connected to the bottom of the injection pipe 3, and the solenoid valve 132 is installed on the feed pipe 131. In this example, the feed pipe 131 is externally connected to a conveying pipe that is connected to the raw material storage tank.

[0031] By adopting the above technical solution, during the mixing of raw materials and foaming agent, the lifting mechanism 6 drives two sets of sealing pistons 5 to descend synchronously. The two sets of sealing pistons 5 simultaneously compress the air in the two sets of mixing tanks 4, increasing the pressure inside. The materials and foaming agent are then discharged into the feeding tank 1 through the two sets of injection pipes 3. Since the two sets of sealing pistons 5 descend at the same speed, a one-to-one ratio of raw materials to foaming agent is achieved. Throughout the process, operators do not need to constantly monitor the descent of materials in the mixing tanks 4, making operation more convenient and improving the efficiency of the mixing process. When the sealing piston 5 descends to its lowest position, the solenoid valve 132 is opened, causing the sealing piston 5 to rise. At this time, the pressure inside the mixing tank 4 increases, and materials are drawn into the mixing tank 4 through the feed pipe 131 for subsequent mixing of raw materials and foaming agent.

[0032] The lifting mechanism 6 is mounted on the feeding tank 1. The lifting mechanism 6 includes a mounting assembly 61, a lifting assembly 62, and a drive assembly 63. The mounting assembly 61 includes a mounting frame 611, a driven column 612, and a driving column 613. The mounting frame 611 is fixed to the top of the feeding tank 1. The driven column 612 is rotatably mounted on the mounting frame 611, and the driving column 613 is rotatably mounted on the mounting frame 611. The number of lifting assemblies 62 is equal to the number of batching tanks 4, and their positions correspond one-to-one. Each lifting assembly 62 includes a vertical rod 621, a connecting rod 622, a horizontal rod 623, and a turntable 624. The vertical rod 621 passes through the top of the batching tank 4 and is slidably connected. The lower end of the vertical rod 621 is fixed to the top of the sealing piston 5. The connecting rod 622 is rotatably mounted on the vertical rod 621, and the horizontal rod 623 is rotatably mounted on the connecting rod 622. The crossbar 623 and the turntable 624 are eccentrically positioned, with the turntable 624 rotatably located at the end of the crossbar 623 away from the connecting rod 622. One turntable 624 is fixed and coaxially mounted with the driven column 612, while the other turntable 624 is fixed and coaxially mounted with the driving column 613.

[0033] The drive assembly 63 is used for the driven column 612 and the driving column 613 to rotate synchronously. The drive assembly 63 includes a drive motor 631, a driving gear 632, a driven gear 633, a main synchronous pulley 634, a driven synchronous pulley 635, and a synchronous belt 636. The drive motor 631 is fixed to the mounting bracket 611, and the driving gear 632 is fixedly sleeved on the drive motor 631. The driven gear 633 is fixedly sleeved on the driving column 613 and meshes with the driving gear 632. The main synchronous pulley 634 is fixedly sleeved on the driving column 613. The driven synchronous pulley 635 is fixedly sleeved on the driven column 612. The synchronous belt 636 is used to connect the main synchronous pulley 634 and the driven synchronous pulley 635, and both the main synchronous pulley 634 and the driven synchronous pulley 635 mesh with the synchronous belt 636.

[0034] During the process of mixing raw materials and foaming agent, the drive motor 631 drives the drive gear 632 to rotate, causing the driven gear 633 meshing with the drive gear 632, the drive pin 613 connected to the driven gear 633, and the main synchronous pulley 634 connected to the drive pin 613 to rotate. Since the synchronous belt 636 is used to connect the main synchronous pulley 634 and the driven synchronous pulley 635, both the main synchronous pulley 634 and the driven synchronous pulley 635 mesh with the synchronous belt 636, thereby causing the driven pin 612 connected to the driven synchronous pulley 635 to rotate. During the rotation of the driven column 612 and the driving column 613, the two sets of turntables 624 connected to the driven column 612 and the driving column 613, the horizontal bar 623 connected to the two sets of turntables 624, and the connecting rod 622 connected to the two sets of horizontal bars 623 all rotate synchronously. In this process, the connecting rod 622 is first forced to lower the sealing piston 5 and compress the air in the mixing tank 4. Finally, the vertical rod 621 drives the sealing piston 5 to rise and return to its original position, thereby achieving the purpose of proportioning the raw materials and foaming agent. Furthermore, controlling the rotation angle of the turntable 624 controls the amount of raw materials and foaming agent mixed each time, allowing for operation of the device according to specific needs.

[0035] A sealing assembly 7 is installed on the injection pipe 3. The sealing assembly 7 prevents material from being discharged from the injection pipe 3 into the feeding tank 1 when the sealing piston 5 is rising or stationary. The sealing assembly 7 includes a connecting plate 71, a mounting sleeve 72, a sliding rod 73, a spring 74, a sealing ball 75, and a sealing sleeve 76. The connecting plate 71 is fixed to the bottom of the injection pipe 3, and the mounting sleeve 72 is fixed to the lower end of the connecting plate 71. The sliding rod 73 is inserted into the inner wall of the mounting sleeve 72, and the spring 74 is fixed between the bottom of the sliding rod 73 and the inner bottom wall of the mounting sleeve 72. The sealing ball 75 is fixed to the upper end of the sliding rod 73 and abuts against the discharge through hole. The sealing sleeve 76 is fixedly sleeved on the sliding rod 73 and slidably connected to the inner side wall of the mounting sleeve 72.

[0036] During the descent of the sealing piston 5, the pressure inside the mixing tank 4 increases, causing the sealing ball 75 to be stressed and descend. This causes the sliding rod 73 connected to the sealing ball 75 and the sealing sleeve 76 connected to the sliding rod 73 to descend as well. The spring 74 is stressed and gradually contracts until the sealing ball 75 separates from the discharge hole. At this point, the material first flows from the discharge hole into the injection pipe 3, and finally flows from the injection pipe 3, the mounting sleeve 72, and the connecting plate 71 into the feeding tank 1. When the sealing piston 5 is stationary, the pressure inside the mixing tank 4 gradually returns to its initial pressure due to the discharge of material. The spring 74 gradually extends and resets, causing the sliding rod 73, the sealing sleeve 76, and the sealing ball 75 to rise and reset until the sealing ball 75 is pressed against the discharge hole. This achieves the purpose of preventing material from flowing from the injection pipe 3 into the feeding tank 1 when the sealing piston 5 is stationary or rising.

[0037] A slide groove 9 is provided through the turntable 624. An adjustment assembly 10 is provided on the turntable 624. The number of adjustment assemblies 10 and the number of slide grooves 9 are equal to the number of turntables 624, and their positions correspond one-to-one. The adjustment assembly 10 includes a slider 101 and a threaded rod 102. The slider 101 is slidably installed within the slide groove 9. A crossbar 623 is rotatably connected to the slider 101, and the threaded rod 102 is rotatably installed within the slide groove 9 and threadedly connected to the slider 101. The threaded rod 102 passes through the top of the slide groove 9 and is rotatably connected. An auxiliary groove 12 is provided at the top of both sets of threaded rods 102.

[0038] Rotating the threaded rod 102 causes the slider 101 threadedly connected to the threaded rod 102, the horizontal bar 623 connected to the slider 101, the connecting rod 622 connected to the horizontal bar 623, the vertical bar 621 connected to the connecting rod 622, and the sealing piston 5 connected to the vertical bar 621 to all rise and fall. This adjusts the distance between the slider 101 and the axis of the turntable 624, as well as the height of the sealing piston 5 inside the mixing tank 4. As the turntable 624 rotates, the distance of the adjustable sealing piston 5 is changed, thus controlling the amount of material discharged from the mixing tank 4 into the feeding tank 1. By adjusting one set of sealing pistons 5, the ratio of material discharged from the two mixing tanks 4 into the feeding tank 1 can be changed, expanding the applicability of the device.

[0039] A mixing assembly 8 is mounted on the feeding tank 1. The mixing assembly 8 includes a mixing rod 81, mixing blades 82, and a mixing motor 83. The mixing rod 81 is rotatably mounted on the inner top wall of the feeding tank 1. The mixing blades 82 are fixed to the mixing rod 81, and the mixing motor 83 is fixed to the top of the feeding tank 1 and drives the mixing rod 81 to rotate. During the process of raw materials and foaming agent entering the feeding tank 1, the mixing motor 83 drives the mixing rod 81 to rotate, causing the mixing blades 82 connected to the mixing rod 81 to rotate and mix the raw materials and foaming agent, thereby increasing the mixing speed of the raw materials and foaming agent.

[0040] An indicator block 11 is fixed on the slider 101, and a scale line is provided on the side wall of the turntable 624 near the indicator block 11. The indicator block 11 and the scale line facilitate the adjustment of the distance between the slider 101 and the axis of the turntable 624.

All technical solutions falling within the scope of this utility model's concept are protected.
