Description

Technical Field

[0001] The invention relates to the field of packaging machinery and equipment, and more particularly to a clamping structure for dispensing bottles of a filling machine. Background Art

[0002] With the development of mechanical automation, many production steps in traditional production processes are gradually replaced by automated machinery, which not only greatly improves production efficiency, but also saves a lot of labor costs. Filling machines are mainly a type of packaging machine, mainly used for fluid packaging. Usually, after a large number of products are uniformly produced, they are packaged according to different bottle capacity specifications through filling machines.

[0003] A Chinese patent application numbered CN201420351393.6 discloses a filling device, including a frame and a filling device and a weighing device mounted on the frame. The filling device is connected to a drainage tube, through which liquid is filled into a sub-filling bottle, and the filling amount is controlled by a weighing device to achieve liquid sub-filling.

[0004] Although the above filling equipment realizes liquid sub-packaging, during the filling process, the sub-filling bottle placed on the weighing device is easily misaligned with the discharge port of the drainage tube due to external force, causing the liquid in the drainage tube to drip outside the sub-filling bottle and cause waste. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a clamping structure for sub-filling bottles of a filling machine, which has the advantage of reducing the waste caused by liquid dripping outside the sub-filling bottle during the filling process.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A clamping structure for filling bottles of a filling machine comprises a filling machine with a discharge port on its outer surface and a clamping piece, wherein the clamping piece is arranged below the discharge port of the filling machine in a vertical direction, the clamping piece comprises a silicone sheet and a lower clamping cover for fixing the silicone sheet, the surface of the silicone sheet away from the lower clamping cover is abutted against an upper clamping cover, a clamping opening for fixing the filling bottles is opened in the middle of the clamping piece, a protrusion is provided on the inner wall of the silicone sheet towards the center direction of the silicone sheet, and a plurality of protrusions are arranged along the circumference of the inner wall of the clamping opening.

[0008] By adopting the above technical solution, the bottle mouth of the sub-filling bottle enters the clamping mouth and the end of the protrusion away from the inner wall of the clamping mouth abuts against the outer surface of the sub-filling bottle, thereby fixing the sub-filling bottle to the outer surface of the filling machine.

[0009] Compared with fixing the bottle body of the sub-filling bottle, the sub-filling bottle is fixed by clamping the bottle mouth, which reduces the restriction on the outer surface shape of the sub-filling bottle; in the process of fixing the sub-filling bottle by the clamping piece, the sub-filling bottle is moved from the bottom of the clamping mouth in the vertical direction, so that the bottle mouth of the sub-filling bottle passes through and protrudes from the clamping mouth, and the protrusion in the clamping mouth limits the movement of the bottle mouth, so that the sub-filling bottle is fixed, the operation is simple, the additional disassembly and installation structure of the sub-filling bottle is reduced, and the production cost is reduced; by arranging the clamping piece below the discharge port in the vertical direction, the bottle mouth of the sub-filling bottle is oriented toward the receiving port The convex part is arranged in a circumferential direction along the inner wall of the clamping mouth, and the bottle mouth is in a stable state under the joint force of the multiple protrusions on the bottle mouth, thereby increasing the contact area between the outer wall of the bottle mouth and the protrusion, thereby increasing the friction between the outer wall of the bottle mouth and the protrusion, and strengthening the fixation of the clamping piece to the bottle mouth.

[0010] Preferably, the number of the protrusions is set to 8 to 10, and the intervals between adjacent protrusions are the same.

[0011] By adopting the above technical scheme, when the number of protrusions is set to be less than 8, the intervals between adjacent protrusions are large, the contact area between the protrusions and the bottle mouth of the sub-packaging bottle is small, and the sub-packaging bottle is easy to fall off from the clamp; when the number of protrusions is set to be greater than 10, the intervals between adjacent protrusions are small, the moving range of the protrusions is small, and it is difficult to clamp the sub-packaging bottle with a larger outer diameter of the bottle mouth; the intervals between adjacent protrusions are the same, so that when the bottle mouth of the sub-packaging bottle passes through the silicone sheet, the forces exerted by each protrusion on the sub-packaging bottle tend to be equal, thereby keeping the sub-packaging bottle stable in the supporting mechanism and reducing the occurrence of the sub-packaging bottle falling from the clamping mechanism due to uneven force.

[0012] Preferably, the filling machine is provided with a scale head bracket arranged in a horizontal direction, one end of the scale head bracket is connected to a weight sensor, and one end of the scale head bracket away from the weight sensor is connected to a clip.

[0013] By adopting the above technical solution, the clip is connected to the weight sensor through the clamping mechanism, so that the clamping mechanism can monitor the weight of the sub-filling bottle in real time while fixing the sub-filling bottle, thereby improving the filling accuracy of the filling machine for the sub-filling bottle.

[0014] Preferably, a neodymium magnet is provided at one end of the scale head bracket away from the weight sensor, and the scale head bracket is magnetically connected to the clip.

[0015] By adopting the above technical solution, the magnetic connection between the scale head bracket and the clip is a detachable connection, and the clip can be replaced to match the outer diameter of the bottle to be packaged; the scale head bracket with a neodymium magnet is connected to the clip by magnetic connection, which reduces the need to set the installation site in the connection between the scale head bracket and the clip, reduces the need to drill holes on the clip, reduces damage to the clip, and protects the clip.

[0016] Preferably, a bracket panel is detachably connected to the surface of the filling machine, the bracket panel has a through hole for accommodating a scale head bracket, an electronic scale bracket is connected to the surface of the bracket panel facing the interior of the filling machine, and the weight sensor is fixed to the upper surface of the electronic scale bracket.

[0017] By adopting the above technical solution, the weight sensor can be removed or installed from the filling machine by removing the bracket panel from the filling machine, and the electronic scale bracket provides a fixed space for the weight sensor on the bracket; since the weight of the sub-filled bottles changes during the filling process, the scale head bracket connected with the clip will move in the vertical direction, and the through hole provides space for the scale head bracket to move, reducing the restriction of the bracket panel on the scale head bracket, thereby reducing the impact on the filling accuracy of the filling machine.

[0018] Preferably, the weight sensor is connected to a control system of the filling machine, and the control system is connected to a flow control mechanism for controlling the flow of liquid in the discharge port.

[0019] By adopting the above technical solution, through the connection between the weight sensor and the control system, when the weight of the sub-bottle fixed in the clamp changes during the filling process of the sub-bottle, the weight is transmitted to the control system through the weight sensor. When the weight sensor detects that the weight of the sub-bottle in the clamp reaches the set value, the control system sends a signal to the flow control mechanism to stop the filling work, thereby realizing the automation of filling and reducing the filling volume difference caused by manual operation.

[0020] Preferably, the flow control mechanism comprises a motor arranged in the filling machine, the output end of the motor is connected with a flow control clamp, the discharge port is connected with a flow guide pipe, and the flow control clamp is sleeved outside the flow guide pipe.

[0021] By adopting the above technical solution, the motor drives the flow control clamp to squeeze the guide tube toward the middle of the guide tube, blocking the flow of liquid in the guide tube, thereby preventing the liquid in the guide tube from continuing to flow into the sub-filling bottle, reducing the impact on the filling accuracy of the filling machine.

[0022] Preferably, an end of the current control clamp away from the motor is connected to a spring sheet, and the spring sheet is arranged to be inclined upward along a horizontal plane toward the flow guide pipe.

[0023] By adopting the above technical solution, since the spring piece is arranged to be inclined upward along the horizontal plane toward the end of the guide tube, the end of the spring piece in contact with the guide tube has a tendency to move upward in the vertical direction during the process of the spring piece squeezing the guide tube, thereby driving the liquid in the guide tube to move upward along the length direction of the guide tube, reducing the internal air pressure at the lower end of the guide tube in the vertical direction, preventing the liquid inside the lower end of the guide tube from dripping under its own gravity, reducing the probability of the liquid in the guide tube continuing to drip into the sub-filling bottle, and improving the filling accuracy.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. The protrusion is used to abut against the outer wall of the bottle mouth of the sub-filling bottle to fix the sub-filling bottle on the outer surface of the filling machine, which reduces the dislocation of the sub-filling bottle from the discharge port of the filling machine during the filling process due to the influence of the external environment, and reduces the waste caused by the liquid to be filled falling outside the sub-filling bottle;

[0026] 2. By connecting the clip and the scale head bracket, the clamping mechanism can monitor the weight change of the sub-filled bottle in real time, thereby improving the filling accuracy;

[0027] 3. The filling work is automated through the clamping mechanism composed of the clamping piece, weight sensor and control system, reducing the filling volume difference caused by manual operation. BRIEF DESCRIPTION OF THE DRAWINGS
