Description

Technical Field

[0001] This utility model specifically relates to an emulsifying pot linkage ratchet feeding device. Background Technology

[0002] Emulsifying pots are used in emulsifying machines. Their main structure includes an automatic lifting pot lid and a tilting pot body. Their main function is to store materials and facilitate mixing (i.e., emulsification). After emulsification, the pot needs to be tilted to pour out the materials inside.

[0003] For example, Chinese utility model patent document with publication number "CN209597107U" discloses a discharging device for an emulsifier. This discharging device mainly consists of the emulsifier body, frame, fixing rod, cylinder rod, fixing frame, and rotating shaft. The rotating shaft is rotatably connected to both ends of the emulsifier body, with the outer end connected to the frame. A third motor and control panel are connected to the right side of the frame. The third motor controls the rotation of the rotating shaft to cause the emulsification pot to tilt, thereby achieving the discharging of the material.

[0004] However, this pouring device has the following drawbacks: it relies on a motor as the main driving and turning component, resulting in poor reliability. In the event of a power outage or motor failure, the force exerted by the motor on the shaft will immediately disappear, leaving the shaft primarily subjected to the force exerted by the emulsifying pot. Due to the weight of the emulsifying pot, the shaft will rotate, causing the pot to swing back and forth and the liquid inside to splash out. If the liquid is corrosive or has high-temperature properties, this poses an extreme danger to workers. Therefore, the pouring device has poor reliability and needs improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an emulsifying pot linkage ratchet unloading device to address the shortcomings of the prior art. This device ensures the continuity and reliability of the operation, effectively locks the position of the rotating shaft, prevents accidental swinging caused by motor failure, reduces liquid splashing or leakage caused by the swinging of the emulsifying pot, and improves operational safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an emulsifying pot linkage ratchet dispensing device, comprising a frame and a rotating shaft rotatably mounted on the frame, one end of the rotating shaft being fixedly connected to the side of the emulsifying pot, characterized in that: a ratchet is linked to the other end of the rotating shaft, the outermost ring of the ratchet having multiple sets of first helical teeth evenly distributed, each set of first helical teeth being inclined in the same direction, pawls distributed on the outside of the ratchet, one end of the pawl having multiple sets of second helical teeth, a hinge shaft rotatably connected to the middle, and a pressure rod linked to the other end, the pressure rod being able to drive the pawl to swing around the hinge shaft, a mounting plate being provided between the frame and the pressure rod, the mounting plate being detachably connected to the frame by screws, a guide cylinder being provided on the upper part of the mounting plate, a sliding groove penetrating the guide cylinder along the axis of the guide cylinder being provided inside the guide cylinder, the pressure rod being movably inserted into the sliding groove, and the hinge shaft being fixed to the mounting plate.

[0007] Using the above technical solution, pushing the pressure rod downwards causes it to slide within the groove, and its lower end drives the pawl to swing around the hinge axis. This causes the second helical tooth on the pawl to separate from the first helical tooth, allowing the ratchet to be rotated manually or by motor, thus rotating the shaft and overturning the emulsifying pot for easy discharge. After discharge, pulling the pressure rod upwards resets it, causing the second helical tooth on the pawl to engage with the first helical tooth, limiting the ratchet and preventing the shaft from rotating. By employing a ratchet and pawl mechanical structure, the improved discharging device no longer relies entirely on motor drive. Even in the event of a power outage or motor failure, this structure allows for manual control of the emulsifying pot's tilting and reset, ensuring continuous and reliable operation. It effectively locks the shaft position, preventing accidental swaying caused by motor failure, thus reducing liquid splashing or leakage caused by the emulsifying pot's swaying, lowering the potential dangers to workers from corrosive or high-temperature liquids, and improving operational safety.

[0008] The aforementioned emulsifying pot linkage ratchet feeding device can be further configured as follows: the lower end of the pressure rod is provided with a strip-shaped hole, the other end of the ratchet is provided with a connecting pin, the end of the connecting pin is movably inserted into the strip-shaped hole, and the upper end of the pressure rod is provided with an operating handle, the lateral dimension of the operating handle being larger than the lateral dimension of the pressure rod.

[0009] Using the above technical solution, the design incorporates a slotted hole and connecting pin to accommodate the oscillation of the pawl and the linear movement of the pressure lever, preventing jamming between the two. An operating handle is added for convenient manual control of the pressure lever.

[0010] The emulsifying pot linkage ratchet feeding device described above can be further configured such that: the other end of the ratchet is also linked to a first return spring, and the end of the first return spring located away from the ratchet is connected to a positioning pin, which is fixed to the mounting plate.

[0011] The above technical solution facilitates the automatic reset of the pawl.

[0012] The aforementioned emulsifying pot linkage ratchet feeding device can be further configured as follows: the frame is provided with a limiting mechanism distributed on one side of the mounting plate. The limiting mechanism includes a limiting pin, a second return spring, a fastener, and a support sleeve. The support sleeve is fixedly installed on the frame. The support sleeve has a sliding hole. The fastener is located at one end of the sliding hole and is threadedly connected to the support sleeve. The limiting pin is located in the sliding hole. The second return spring is located in the sliding hole. One end of the second return spring is in contact with the fastener, and the other end of the second return spring is in contact with the limiting pin. The limiting pin can contact the side of the mounting plate under the push of the second return spring.

[0013] By adopting the above technical solution, the limiting pin can make tight contact with the side of the mounting plate under the push of the second return spring, thereby effectively preventing the mounting plate from shaking and ensuring the stability of the entire unloading device during operation. In addition, the limiting mechanism also allows workers to manually adjust the limiting position when needed, improving the applicability and flexibility of the limiting mechanism.

[0014] The aforementioned emulsifying pot linkage ratchet feeding device can be further configured as follows: an installation assembly is provided between the ratchet and the rotating shaft. The installation assembly includes a front mounting circular plate and a rear mounting flange plate. The rear mounting flange plate has a cylindrical hole shaft sleeved on the outer circumference of the rotating shaft in the middle. The cylindrical hole shaft and the rotating shaft are fastened together by a pin. The front mounting circular plate is sleeved on the cylindrical hole shaft and the two are interference-fitted. The ratchet is sleeved on the cylindrical hole shaft and distributed between the front mounting circular plate and the rear mounting flange plate. The ratchet has multiple sets of fan-shaped grooves in the middle. The front mounting circular plate has a set of screw holes corresponding to each set of fan-shaped grooves. The front mounting circular plate and the ratchet are connected by bolts. The bolts pass through the fan-shaped grooves and the screw holes in sequence.

[0015] The above technical solution includes a front mounting plate, a rear mounting flange, and related fastening elements. These components work together to achieve precise alignment between the ratchet and the rotating shaft. The cylindrical bore of the rear mounting flange is fitted onto the outer circumference of the rotating shaft and fastened to it with a pin, ensuring the stability of the connection between the rear mounting flange and the rotating shaft. The front mounting plate is fitted onto the cylindrical bore and has an interference fit, increasing the tightness of the connection between the front mounting plate and the rear mounting flange. The ratchet is fitted onto the cylindrical bore and located between the front mounting plate and the rear mounting flange. This arrangement allows the ratchet to stably transmit torque. The fan-shaped groove in the middle of the ratchet corresponds to the screw holes on the front mounting plate and is connected by bolts. This facilitates the assembly and disassembly of the ratchet and the front mounting plate and allows the installation angle of the ratchet to be adjusted according to actual conditions for better engagement with the pawl.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3The emulsifying pot linkage ratchet feeding device shown includes a frame 1 and a rotating shaft 2 rotatably mounted on the frame 1. One end of the rotating shaft 2 is fixedly connected to the side of the emulsifying pot, and the other end of the rotating shaft 2 is linked to a ratchet 3. The outermost ring of the ratchet 3 has multiple sets of first helical teeth 4 evenly distributed, and each set of first helical teeth 4 is inclined in the same direction. Pads 5 are distributed on the outside of the ratchet 3. One end of the pawl 5 is provided with multiple sets of second helical teeth 6, the middle is rotatably connected to a hinge shaft 7, and the other end is linked to a pressure rod 8. The pressure rod 8 can drive the pawl 5 to swing around the hinge shaft 7. A mounting plate 9 is provided between the frame 1 and the pressure rod 8. The mounting plate 9 is detachably connected to the frame 1 by screws. A guide cylinder 10 is provided on the upper part of the mounting plate 9. A sliding groove 11 is provided inside the guide cylinder 10 along the axis of the guide cylinder 10. The pressure rod 8 is movably inserted into the sliding groove 11. The hinge shaft 7 is fixed on the mounting plate 9. Pushing the pressure rod 8 downwards causes it to slide within the groove 11, and its lower end drives the pawl 5 to swing around the hinge shaft 7. This causes the second helical tooth 6 on the pawl 5 to separate from the first helical tooth 4, allowing the ratchet 3 to be rotated manually or by motor, thus rotating the shaft 2 and turning the emulsifying pot over for easy discharge. After discharge, pulling the pressure rod 8 upwards resets it, causing the second helical tooth 6 on the pawl 5 to engage with the first helical tooth 4, limiting the ratchet 3 and preventing the shaft 2 from rotating. By adopting the mechanical structure of the ratchet 3 and pawl 5, the improved discharging device no longer relies entirely on motor drive. Even in the event of a power outage or motor failure, this structure allows for manual control of the emulsifying pot's tilting and resetting, ensuring continuous and reliable operation. It effectively locks the position of the shaft 2, preventing accidental swaying caused by motor failure, thus reducing liquid splashing or leakage caused by the emulsifying pot's swaying, lowering the potential danger to workers from corrosive or high-temperature liquids, and improving operational safety.

[0023] The lower end of the pressure lever 8 has a slotted hole 12, and the other end of the pawl 5 has a connecting pin 13. The end of the connecting pin 13 is movably inserted into the slotted hole 12. The upper end of the pressure lever 8 has an operating handle 14, the lateral dimension of which is larger than the lateral dimension of the lever 8. The design of the slotted hole 12 and the connecting pin 13 is to accommodate the swinging motion of the pawl 5 and the linear motion of the pressure lever 8, preventing them from jamming. The addition of the operating handle 14 facilitates manual control of the pressure lever 8.

[0024] The other end of the pawl 5 is also linked to a first return spring 15. The end of the first return spring 15 located away from the pawl 5 is connected to a positioning pin 16, which is fixed to the mounting plate 9. This facilitates the automatic reset of the pawl 5.

[0025] The frame 1 is equipped with a limiting mechanism 17 distributed on one side of the mounting plate 9. The limiting mechanism 17 includes a limiting pin 18, a second return spring 19, a fastener 20, and a support sleeve 21. The support sleeve 21 is fixedly installed on the frame 1 and has a sliding hole 22 inside. The fastener 20 is located at one end of the sliding hole 22 and is threadedly connected to the support sleeve 21. The limiting pin 18 is located in the sliding hole 22, and the second return spring 19 is located inside the sliding hole 22. One end of the second return spring 19 is in contact with the fastener 20, and the other end is in contact with the limiting pin 18. Under the push of the second return spring 19, the limiting pin 18 can abut against the side of the mounting plate 9. The limiting pin 18 can abut against the side of the mounting plate 9 under the push of the second return spring 19, thereby effectively preventing the mounting plate 9 from shaking and ensuring the stability of the entire unloading device during operation. In addition, the limit mechanism 17 allows workers to manually adjust the limit position when needed, improving the applicability and flexibility of the limit mechanism 17.

[0026] A mounting assembly 22 is provided between the ratchet 3 and the rotating shaft 2. The mounting assembly 22 includes a front mounting circular plate 23 and a rear mounting flange plate 24. The rear mounting flange plate 24 has a cylindrical bore shaft 25 in the middle, which is fitted onto the outer circumference of the rotating shaft 2. The cylindrical bore shaft 25 and the rotating shaft 2 are fastened together by a pin. The front mounting circular plate 23 is fitted onto the cylindrical bore shaft 25 with an interference fit. The ratchet 3 is fitted onto the cylindrical bore shaft 25 and is distributed between the front mounting circular plate 23 and the rear mounting flange plate 24. The ratchet 3 has multiple sets of fan-shaped slots 26 in the middle. The front mounting circular plate 23 has a set of screw holes corresponding to each set of fan-shaped slots 26. The front mounting circular plate 23 and the ratchet 3 are connected by bolts, which pass through the fan-shaped slots 26 and the screw holes in sequence. The mounting assembly 22 includes the front mounting circular plate 23, the rear mounting flange plate 24, and related fastening elements. These components work together to achieve precise docking between the ratchet 3 and the rotating shaft 2. The cylindrical bore shaft 25 of the rear mounting flange 24 is sleeved on the outer circumference of the rotating shaft 2 and fastened to the rotating shaft 2 by a pin, ensuring the connection stability between the rear mounting flange 24 and the rotating shaft 2. The front mounting circular plate 23 is sleeved on the cylindrical bore shaft 25 and is interference-fitted with it, increasing the tightness of the connection between the front mounting circular plate 23 and the rear mounting flange 24. The ratchet 3 is sleeved on the cylindrical bore shaft 25 and located between the front mounting circular plate 23 and the rear mounting flange 24. This layout allows the ratchet 3 to stably transmit torque. The fan-shaped groove 26 designed in the middle of the ratchet 3 corresponds to the screw hole on the front mounting circular plate 23 and is connected by bolts. This facilitates the disassembly and assembly of the ratchet 3 and the front mounting circular plate 23, and also allows the installation angle of the ratchet 3 to be adjusted according to actual conditions for better cooperation with the pawl 5.

[0027] The working principle of material discharge in this embodiment is as follows: When the pressure rod 8 is pushed downward, it slides in the groove 11 inside the guide cylinder 10, causing the pawl 5 to swing and the second helical tooth 6 to separate from the first helical tooth 4. At this time, the ratchet 3 can be rotated manually or by a motor, thereby driving the rotating shaft 2 and the emulsifying pot to flip, facilitating material discharge. After material discharge is completed, the pressure rod 8 is pulled upward, and the pawl 5 automatically resets under the action of the first return spring 15. The second helical tooth 6 re-engages into the first helical tooth 4, locking the ratchet 3 and preventing the rotating shaft 2 from rotating freely.
