Description

Technical Field

[0001] The utility model relates to the technical field of ointment filling, in particular to an ointment precision-controlled filling device. Background Art

[0002] Ointment is a dosage form made by boiling the drug with water or vegetable oil and removing the residue. There are two types: oral and external use. There are three types of oral use: decoction, fluid extract and extract; there are two types of external use: ointment and hard plaster. Hard plaster can be divided into black plaster and rubber plaster according to the different bases used.

When the working environment temperature is lower than the standard filling temperature, the electric heating box and the air guide fan are started by an external control device, and the heat generated after the electric heating box is powered on is blown out along the air guide ring tube inside the heating plate under the wind pressure of the air guide fan, and the hot air is blown to the filling tube surface of the filling joint, and the hot air is relatively evenly blown to the filling tube from multiple directions, keeping the temperature of the filling tube surface suitable for the normal circulation of the paste, so that during the filling process, the paste can be evenly and smoothly discharged from the opening position of the filling tube, thereby improving the accuracy of the filling.

[0004] According to the above patent, hot air is used to heat the filling tube to keep the paste temperature inside the filling tube at an appropriate level. However, since the heat transfer coefficient of hot air is low, the efficiency of hot air heating the filling tube is not high. In addition, when the hot air comes into contact with the filling tube, it will mix with the air at normal temperature, causing most of the heat to be carried away by the air at normal temperature, resulting in low utilization rate of thermal energy and increased cost of maintaining the temperature of the filling tube.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0024] Reference Figure 1 - Figure 5The utility model discloses a precise control filling device for ointment, comprising a base 1, a filling rack 2 is fixedly connected to one side of the top of the base 1, a filling head 3 is fixedly connected to the bottom of the filling rack 2, a plurality of filling tubes 4 for filling ointment are arranged at equal intervals in the horizontal direction on the side of the filling head 3 away from the filling rack 2, a sleeve 5 is arranged at the bottom of the filling head 3, the sleeve 5 is provided with a number of through grooves 6 equal to the number of the filling tubes 4 in the horizontal direction, and the filling tubes 4 are connected one by one, the inner side wall of the through groove 6 is concave to form a heating cavity 7 for heating the filling tube 4, a water tank 8 is fixedly connected to the outer wall of the filling rack 2 on the side close to the filling tube 4, and a diversion component 9 for inputting hot water into the heating cavity 7 is arranged on the outer wall of the water tank 8.

[0025] In this embodiment, observe Figure 1 It can be found that a placement groove for placing a container is provided on the top of the base 1, which can be used to place the container for the ointment at the bottom of the filling tube 4. After the container is placed, the filling head 3 of the filling rack 2 is used to squeeze the ointment through the filling tube 4 to complete the filling of the ointment.

[0026] Because the paste will change its viscosity due to the influence of temperature, the extrusion amount of the paste will change, affecting the filling accuracy of the paste. Therefore, a shell 5 is provided on the outer wall of the filling tube 4 of the paste. The shell 5 can provide insulation effect for the filling tube 4 to reduce the influence of the external temperature on the paste.

[0027] Since the paste will dissipate heat naturally, the heat preservation treatment alone cannot effectively ensure the consistency of the paste's flow viscosity. Figure 3 It can be found that a heating chamber 7 is provided in the casing 5. Figure 2 It can be found that the water tank 8 is connected to the casing 5 through the shunt component 9, and the hot water in the water tank 8 can be transported to the heating chamber 7 through the shunt component 9 to heat the filling tube 4, which can be used to compensate for the heat naturally lost by the ointment, so as to ensure the consistency of the flow viscosity of the ointment, make the filling accuracy of the ointment higher, and keep the amount of ointment in each container consistent.

[0028] Among them, the above method adopts the heat exchange method of hot water, using the heat storage capacity of water which is much higher than that of air, which can effectively extend the heating time of the filling tube 4 by hot water. At the same time, the hot water is isolated from the outside world by the shell 5, which can reduce the heat loss of hot water, thereby improving the heat utilization efficiency and effectively reducing the cost required to maintain the temperature of the filling tube 4.

[0029] In a further preferred embodiment of the present invention, Figure 3As shown, the diversion assembly 9 includes a water pump 91, a water outlet pipe 92, a water inlet pipe 93, a transfer pipe 94 and a diversion pipe 95. The water outlet pipe 92 and the water inlet pipe 93 are respectively connected to the top and the bottom of the water tank 8. The water inlet pipe 93 and the end of the water outlet pipe 92 away from the water tank 8 are fixedly connected with a transfer pipe 94. The transfer pipe 94 is close to the casing 5 and is horizontally provided with a number of diversion pipes 95 equal to the number of the heating chamber 7, and is connected to the heating chamber 7. The middle part of the water outlet pipe 92 is provided with a water pump 91 for driving the flow of hot water.

[0030] In this embodiment, the water in the water tank 8 can be pumped out through the water outlet pipe 92 by the provided water pump 91, and then the hot water is diverted into each diversion pipe 95 by the transfer pipe 94, and then the hot water is injected into the independent heating chamber 7 through the independent diversion pipe 95, so as to heat each independent filling tube 4 and compensate for the heat loss of the paste in the corresponding filling tube 4.

[0031] Because the hot water compensates for the heat loss of the paste in the filling tube 4, the temperature of the hot water itself will drop, which will cause the effect of hot water in maintaining the temperature of the paste in the filling tube 4 to deteriorate. Figure 3 It can be found that a shunt pipe 95 is also provided at the bottom of the heating chamber 7. At this time, as the water pump 91 continues to pump in hot water, the new hot water will squeeze out the old hot water through the shunt pipe 95 at the bottom of the heating chamber 7. The old hot water will then converge in the corresponding transfer pipe 94 through the shunt pipe 95, and then flow back into the water tank 8 through the water inlet pipe 93 for heating, so as to complete the circulation of hot water, so that the hot water in the heating chamber 7 can always keep the filling tube 4 at a suitable temperature.

[0032] In a further preferred embodiment of the present invention, Figure 3 As shown, the transfer pipe 94 connected to the water outlet pipe 92 is provided with pressure valves 10 equal in number to the diversion pipes 95 , and are arranged one by one at the intersection of the diversion pipes 95 and the transfer pipe 94 .

[0033] In the present embodiment, because the cross-section of the water outlet end of the water outlet pipe 92 is much smaller than the sum of the cross-sections of the water inlet ends of the multiple diversion pipes 95, the water outlet pipe 92 cannot cover all the diversion pipes 95, so the hot water at the output end of the water outlet pipe 92 will be discharged preferentially through the nearest diversion pipe 95, resulting in the water flow velocity in the diversion pipe 95 close to the water outlet pipe 92 being higher than the water flow velocity in the remaining diversion pipes 95, resulting in differences in the hot water circulation speeds in different diversion pipes 95, thereby affecting the viscosity of the paste in different filling tubes 4, resulting in slight differences in the filling amount.

[0034] Therefore, a pressure valve 10 is provided in the transfer pipe 94 located on one side of the water outlet pipe 92, and the number of the pressure valves 10 is the same as the number of the branch pipes 95, so that each pressure valve 10 is connected to the corresponding branch pipe 95, so that the hot water entering the transfer pipe 94 will be blocked by the pressure valve 10 and cannot be discharged until the hot water fills the transfer pipe 94. The water pressure in the transfer pipe 94 will increase with the continuous pumping of the water pump 91 until the water pressure exceeds the threshold of the pressure valve 10. The pressure valve 10 then opens synchronously to allow the hot water to enter the branch pipe 95 synchronously, which can be used to ensure that the water flow rate in each branch pipe 95 is the same, so that the hot water circulation speed in different heating chambers 7 is kept consistent, thereby keeping the filling accuracy of the filling tube 4 consistent.

[0035] In a further preferred embodiment of the present invention, Figure 5 As shown, a heating wire 11 for heating water is fixedly connected in the water tank 8, and the heating wire 11 is located between the water inlet pipe 93 and the water outlet pipe 92. The outer wall of the water tank 8 is connected to a controller 12 for controlling the heating temperature of the heating wire 11.

[0036] In this embodiment, by arranging an electric heating wire 11 in the water tank 8, it can be used to heat the hot water in the water tank 8, so that the hot water in the heating chamber 7 always maintains a suitable heating temperature, thereby ensuring that the flow viscosity of the ointment in the filling tube 4 is consistent, and by arranging a controller 12 on the outside of the water tank 8, it can be used to control the heating temperature of the electric heating wire 11 to meet the filling temperature requirements of a variety of different ointments.

[0037] By locating the heating wire 11 between the water inlet pipe 93 and the water outlet pipe 92, the low-temperature water returning from the water inlet pipe 93 can be heated by the heating wire 11 when entering the water outlet pipe 92. This can prevent the hot water heated by the heating wire 11 from pushing the low-temperature water upward when diffusing upward, causing the hot water and the low-temperature water to mix and affect the temperature control, thereby making the temperature control effect of the controller 12 better.

[0038] In a further preferred embodiment of the present invention, Figure 3 As shown, a heat-conducting sleeve 13 is fixedly connected to the opening of the heating chamber 7, and the top and bottom of the heat-conducting sleeve 13 are respectively in contact with the inner top wall and inner bottom wall of the heating chamber 7, so that the heat-conducting sleeve 13 separates the heating chamber 7 from the filling tube 4.

[0039] In this embodiment, the heat-conducting sleeve 13 is provided to prevent hot water from directly contacting the outer wall of the filling tube 4 and causing corrosion of the filling tube 4, and to effectively improve the protection of the filling tube 4 to prevent the filling tube 4 from being damaged and causing hot water to be injected into the paste and causing the paste to be contaminated.

[0040] In a further preferred embodiment of the present invention, Figure 2As shown, a water inlet 14 and a water outlet 15 are respectively provided at the top of the water tank 8 , and a filter 16 is provided in the middle of the water inlet 14 .

[0041] In this embodiment, the water inlet 14 and the water outlet 15 are provided to replace the water in the water tank 8, and a filter 16 is provided in the middle of the water inlet 14 to perform preliminary filtration on the water entering the water tank 8 to reduce impurities in the water, thereby reducing scale generated after the water is heated, so as to avoid scale adhering to the heat conductive sleeve 13 and affecting the heat conduction efficiency.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
