Description

Technical Field

[0001] The utility model relates to the field of manual filling machines, in particular to a quantitative manual filling machine. Background Art

[0002] Filling machines can be divided into manual filling machines, semi-automatic filling machines and fully automatic filling machines according to the degree of automation. Most of the existing liquid or paste filling machines use CNC to perform fully automatic or semi-automatic filling. For home workshops or small and micro factories with low workload, the price of automated equipment is high, the maintenance cost is high, and the cost performance is extremely low. Therefore, home workshops and small and micro factories often use more flexible and simple manual filling machines.

[0003] When unloading materials from traditional manual filling machines, the filling personnel need to keep a close eye on the filling bottles or bags to ensure the filling volume. It is impossible to accurately determine the filling volume before filling, which is prone to operating errors such as overfilling or underfilling. At the same time, most manual filling machines have fixed discharge ports, which generally cannot be adjusted or can only slightly adjust the height of the filling nozzle. When filling bottles with high filling heights, due to the large height difference between the filling nozzle and the bottom of the filling bottle, it is easy to generate a lot of foam or cause raw materials to splash, thus affecting the filling effect.

[0023] Reference Figure 1-4 , the working principle of this embodiment:

[0024] When filling is required, the user can push the operating rod 891 backwards, and the adjusting wheel 892 in the operating rod 891 can push the second driving wheel 62 to reverse, and the second driving wheel 62 reverses to drive the driving screw 61 to reverse, and the quantitative piece 64 screwed to the driving screw 61 will gradually rise, and the rise of the quantitative piece 64 drives the push plate 66 to rise along the inner wall of the quantitative cylinder 4, thereby releasing the blockage of the feeding pipe 5 and the through hole 82; at the same time, since the inner cavity of the quantitative cylinder 4 is a sealed environment, when the push plate 66 rises, the liquid generated in the cavity The low pressure and the atmospheric pressure form a pressure difference, and the raw materials in the feed hopper 3 will be pressed into the metering cylinder 4 through the delivery pipe 5 by the atmospheric pressure. The user can push the operating rod 891 backward to different degrees according to the position of the push plate 66 and the scale line 9 on the upper end of the metering cylinder 4 to adjust the filling amount of raw materials, thereby realizing the function of regulating the filling amount before filling; after the quantitative measurement is completed, it is only necessary to press the operating rod 891 forward and downward. When the operating rod 891 rotates, the worm 89 at the tail of the operating rod 891 will drive the first driving wheel 88 to rotate, and when the first driving wheel 88 rotates, The meshing teeth 71 drive the discharge pipe 7 to move downward, and the discharge pipe 7 can be inserted into the filling bottle or filling bag for filling, so as to avoid the large height difference between the discharge pipe 7 and its bottom, which may cause the raw material to fall and produce foam or splash out of the filling bottle due to excessive impact force; at the same time, when the operating rod 891 is pressed forward, the adjusting wheel 892 in the worm 89 can reverse the operation in the quantitative mechanism 6, push the push plate 66 to move downward along the inner wall of the quantitative cylinder 4 and squeeze the raw material in the quantitative cylinder 4 downward. Due to the setting of valve 51, the raw materials cannot pass into the feeding pipe 5. When the raw materials are squeezed downward, the raw materials can only flow into the through hole 82. When the squeezing force is greater than the elastic force of the spring 86 at the through hole 82, the baffle 85 will move downward along the telescopic rod 84 to open the through hole 82. At this time, the raw materials can enter the discharge pipe 7 through the through hole 82 for filling, thereby completing the filling function of the filling machine; when all the raw materials are squeezed into the discharge port, the squeezing force disappears, and the baffle 85 can be restored under the push of the spring 86 to seal the through hole 82 again and restore itself.

[0025] Reference Figure 1-4 As a specific embodiment of the improvement, this quantitative manual filling machine includes a base 1, a support frame 2 is provided at the upper end of the base 1, and is characterized in that a feed hopper 3 is provided above the support frame 2, a quantitative cylinder 4 is provided at the lower end of the feed hopper 3, a delivery pipe 5 is connected to the lower end of the feed hopper 3, and the other end of the delivery pipe 5 is connected to the side wall of the bottom end of the quantitative cylinder 4, a quantitative mechanism 6 is provided in the quantitative cylinder 4, and a discharge pipe 7 is provided at the lower end of the quantitative cylinder 4, and the discharge pipe 7 is connected to the quantitative cylinder 4 through an extension mechanism 8.

[0026] Through the setting of the quantitative mechanism 6, when filling is required, the user can push the operating rod 891 backward to drive the quantitative sheet 64 in the quantitative mechanism 6 to gradually rise along the outer side of the driving screw 61 through the operating rod 891, thereby driving the push plate 66 to rise along the inner wall of the quantitative cylinder 4. During the rising process of the push plate 66, the blockage of the feed pipe 5 and the through hole 82 will be released. At the same time, the low pressure generated in the quantitative cylinder 4 when the push plate 66 rises will suck the raw materials in the feed hopper 3 into the quantitative cylinder 4 through the feed pipe 5. At this time, the user can push the operating rod 891 backward to different degrees according to the filling needs to adjust the amount of raw materials sucked in, thereby realizing precise control of the quality of the filling raw materials before filling.

[0027] Through the setting of the extension mechanism 8, after the user has quantitatively drawn the filling raw materials into the metering cylinder 4 through the metering mechanism 6, he only needs to press the operating rod 891 forward and downward. When the operating rod 891 rotates, the first driving wheel 88 in the extension mechanism 8 can drive the discharge pipe 7 to move downward. At this time, the discharge pipe 7 can be inserted into the filling bottle or filling bag for filling, avoiding a large height difference between the discharge pipe 7 and its bottom, resulting in excessive impact force when the raw materials fall to produce foam or splashing of the raw materials out of the filling bottle, thereby improving the filling effect.

[0028] Reference Figure 2-3 As an improved specific embodiment, the extension mechanism 8 includes a shell 81, the shell 81 is fixed to the lower end of the quantitative cylinder 4, the shell 81 is provided with a through hole 82, the through hole 82 is connected to the lower end of the quantitative cylinder 4, a support rod 83 is horizontally fixed in the through hole 82, the middle section of the support rod 83 is arranged on the telescopic rod 84, the upper end of the telescopic rod 84 is provided with a baffle 85 for blocking the through hole 82, and the outer side of the telescopic rod 84 is also provided with a spring 86 for supporting the baffle 85, the upper and lower ends of the spring 86 are abutted between the support rod 83 and the baffle 85, and the lower end of the through hole 82 is fixed A telescopic tube 87 is provided, and the telescopic tube 87 is connected between the discharge tube 7 and the through hole 82. The side wall of the discharge tube 7 is also provided with meshing teeth 71, and the meshing teeth 71 are meshed with the first driving wheel 88. The first driving wheel 88 is rotatably connected in the shell body 81. The side wall of the shell body 81 is also provided with a worm 89 for driving the first driving wheel 88. One end of the worm 89 passes through the shell body 81 and is rotatably connected to the side wall of the shell body 81, and the other end is meshed with the meshing teeth 71 above the first driving wheel 88. One end of the worm 89 passing through the shell body 81 is also provided with an operating rod 891 for adjusting the extension mechanism 8.

[0029] Through the setting of the extension mechanism 8, after the user quantitatively draws the filling raw material into the quantitative cylinder 4 through the quantitative mechanism 6, he only needs to press the operating rod 891 forward and downward. When the operating rod 891 rotates, it can drive the worm 89 at its tail to rotate. When the worm 89 rotates, it will drive the first driving wheel 88 to rotate. When the first driving wheel 88 rotates, it will drive the discharge pipe 7 to move downward through the meshing teeth 71 on the side wall of the discharge pipe 7. At this time, the discharge pipe 7 can be inserted into the filling bottle or the filling bag for filling, so as to avoid the large height difference between the discharge pipe 7 and its bottom, resulting in excessive impact force when the raw material falls, foam or splashing of the raw material out of the filling bottle. At the same time, the telescopic tube 87 can be unfolded or retracted following the movement of the discharge pipe 7, so as to ensure the normal conveying function of the raw material when the discharge pipe 7 moves.

[0030] At the same time, the spring 86 and the baffle 85 are combined and arranged. When the user presses the operating rod 891 forward to adjust the position of the discharge pipe 7, the adjusting wheel 892 in the worm 89 can push the second driving wheel 62 to rotate, and the second driving wheel 62 will drive the driving screw 61 to rotate in situ. At this time, the quantitative piece 64 screwed to the driving screw 61 will gradually move downward along the outer side of the driving screw 61. During the downward movement of the quantitative piece 64, the piston shaft 65 will drive the push plate 66 to move downward along the inner wall of the quantitative cylinder 4. During the downward movement of the push plate 66, the raw material in the quantitative cylinder 4 will be squeezed downward. When the squeezing force is greater than the elastic force of the spring 86 at the through hole 82, the baffle 85 will move downward along the telescopic rod 84 to open the through hole 82. At this time, the raw material can enter the discharge pipe 7 through the through hole 82 for filling. When the raw material is completely squeezed into the discharge port, the baffle 85 can be restored and sealed again under the push of the spring 86, thereby preventing the raw material from leaking from the through hole 82 when the quantitative mechanism 6 quantifies the raw material.

[0031] At the same time, the meshing teeth 71 are only distributed on the side wall from the tail end to the middle of the discharge pipe 7. When the metering mechanism 6 is metered, the first driving wheel 88 is only meshed with the bottom part of the meshing teeth 71. When the first driving wheel 88 rotates, it will not continue to drive it to move upward, thereby avoiding the influence of the metering mechanism 6 on the extension mechanism 8 when metering.

[0032] Reference Figure 2 As an improved specific implementation, the through hole 82 is designed to be smaller at the top and larger at the bottom, and the baffle 85 is the same size as the upper end of the through hole 82.

[0033] Through the arrangement of the baffle 85 and the through hole 82, when the filling machine is not filling, the baffle 85 is pushed by the elastic force of the spring 86 to always abut against the upper end of the through hole 82, closing the through hole 82 to prevent leakage of raw materials; when the filling machine is filling, the raw materials are squeezed to flow downward and the thrust is greater than the baffle 85, the raw materials push the baffle 85 to move backward, and the raw materials can flow into the discharge pipe 7 through the gap at the lower end for filling. The combination of the two can realize the sealing and opening functions of the through hole 82, thereby ensuring the normal operation of the filling machine.

[0034] Reference Figure 2-3 As an improved specific embodiment, an adjusting wheel 892 is provided at the worm 89 in the shell 81, and the quantitative mechanism 6 includes a driving screw 61, the top of the driving screw 61 is rotatably connected to the bottom of the feed hopper 3, and the bottom end of the driving screw 61 passes through the shell 81 and is placed in the shell 81, and a second driving wheel 62 is fixed to the bottom end of the driving screw 61, and the second driving wheel 62 is meshed with the adjusting wheel 892, and the second driving wheel 62 is driven by the adjusting wheel 892, and the driving screw 61 is located on the outer part of the shell 81 and is screwed with a quantitative sheet 64, and a piston shaft 65 is also provided at the lower end of the quantitative sheet 64, and a push plate 66 for sucking raw materials is provided in the piston shaft 65, and the push plate 66 is movably connected to the quantitative cylinder 4, and when the push plate 66 is not in operation, it is placed at the bottom of the quantitative cylinder 4 to block the through hole 82 and the feed pipe 5, and when the push plate 66 is in operation, the feed pipe 5 can be unblocked and the baffle 85 can be pushed to open the through hole 82.

[0035] Through the setting of the quantitative mechanism 6, when filling is required, the user can push the operating rod 891 backwards, and the adjusting wheel 892 in the operating rod 891 can push the second driving wheel 62 to reverse, and the second driving wheel 62 will drive the driving screw 61 to reverse in situ. At this time, the quantitative sheet 64 screwed to the driving screw 61 will gradually rise along the outer side of the driving screw 61. During the rising period of the quantitative sheet 64, the piston shaft 65 will drive the push plate 66 at the lower end to rise. When the push plate 66 rises along the inner wall of the quantitative cylinder 4, it will release the The feed pipe 5 and the through hole 82 are blocked. At the same time, since the inner cavity of the metering cylinder 4 is a sealed environment, when the push plate 66 rises, the low pressure generated in the cavity forms a pressure difference with the atmospheric pressure, and the raw materials in the feed hopper 3 will be pressed into the metering cylinder 4 through the feed pipe 5 by the atmospheric pressure. At this time, the user can compare the position of the push plate 66 with the position of the scale line 9 at the upper end of the metering cylinder 4 according to the filling requirements, and push the operating rod 891 backward to different degrees to adjust the filling amount of raw materials, thereby realizing precise control of the quality of the filling raw materials before filling.

[0036] Reference Figure 2 As an improved specific implementation, a rubber plug 661 is sleeved on the outer side of the push plate 66.

[0037] By disposing the rubber plug 661 , the rubber plug 661 wrapped around the outer side of the push plate 66 can better fit the push plate 66 with the metering cylinder 4 , thereby preventing the raw material from leaking from the gap.

[0038] Reference Figure 1 As an improved specific implementation, it is characterized in that a check valve 51 is provided in the feed conveying pipe 5 .

[0039] By setting the check valve 51, it is possible to prevent the raw materials in the feeding pipe 5 from flowing back and affecting the accuracy of the quantitative mechanism 6, thereby improving the quantitative effect.

[0040] Reference Figure 1 As an improved specific implementation, the quantitative cylinder 4 is made of a transparent material, and a scale line 9 is provided on the front end side wall of the quantitative cylinder 4 .

[0041] By making the metering cylinder 4 of transparent material, the user can observe the position of the liquid or the baffle 85 in the metering cylinder 4 and compare it with the scale line 9 to adjust the raw material content before filling, thereby improving the filling accuracy.
