Description

Technical Field

[0001] The present invention relates to the technical field of filling, and particularly to an automatic filling device. Background Art

[0002] Existing filling devices generally adopt a linear assembly line. When the container moves below the filling head, the filling head descends and injects liquid for filling. The problems of this type of device are as follows: On the one hand, the linear assembly line device occupies a large space, and filling devices generally need to be set in a dust-free and clean space, so the production cost is high; on the other hand, in this type of device, the container is generally transported dynamically by a conveyor belt, and the position of the filling mechanism is designed to be fixed. Therefore, when the container reaches the filling mechanism, the conveyor belt needs to stop moving, and after filling is completed, it needs to be started again. This leads to frequent start-stop of the entire production line, low production efficiency, and relatively large equipment noise and losses. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an automatic filling device to solve the technical problems of low production efficiency and large space occupation of existing filling devices.

[0048] Please refer to Figures 2 to 5 , this embodiment provides a liquid filling head, which includes: a first pipe fitting 311, a second pipe fitting 313, an elastic member 312, and an infusion tube 314; the lower part of the first pipe fitting 311 is sleeved on the upper part of the second pipe fitting 313, the elastic member 312 has a top end 3121 and a bottom end 3122, the elastic member 312 is sleeved outside the first pipe fitting 311 and the second pipe fitting 313, and the top end 3121 abuts against the outer wall of the first pipe fitting 311, the bottom end 3122 abuts against the outer wall of the second pipe fitting 313, the infusion tube 314 penetrates through the through cavities of the first pipe fitting 311 and the second pipe fitting 313, that is, through cavities are provided inside both the first pipe fitting 311 and the second pipe fitting 313, and the lower end of the infusion tube 314 extends out of the second pipe fitting 313.

[0049] In this embodiment, the elastic member 312 is a spring, and the spring is sleeved outside the first pipe fitting 311 and the second pipe fitting 313. In other embodiments, the elastic member 312 can be an elastic sleeve, an elastic sheet, etc. Its function is that after the first pipe fitting 311 and the second pipe fitting 313 are sleeved, when an external pressure is applied, the relative positions of the first pipe fitting 311 and the second pipe fitting 313 can be changed. As will be introduced below, the change in the relative positions of the first pipe fitting 311 and the second pipe fitting 313 is to control the opening or closing of the liquid outlet of the infusion tube 314.

[0050] Specifically, as Figure 2 shown, the first pipe fitting 311 includes: a pipe body 3111, a limiting portion 3112 is provided on the outer wall of the pipe body 3111, and the top end 3121 of the elastic member 312 abuts against the limiting portion 3112.

[0051] Among them, the limiting portion 3112 is an annular platform portion protruding from the outer wall of the pipe body 3111. In this embodiment, the annular platform portion is provided at the middle position of the pipe body 3111.

[0052] Please refer to again Figure 3 , the second pipe fitting 313 includes: a tubular body 3131, a limiting platform 3132 extending outward from the peripheral edge of the lower end of the tubular body 3131, and a hollow tube 3133 extending from the lower end face of the tubular body 3131. The bottom end 3122 of the elastic member 312 abuts against the limiting platform 3132, and the lower part of the infusion tube 314 penetrates through the hollow tube 3133. It can also be understood as: a limiting platform 3132 is provided at the lower end of the tubular body 3131, a communication hole communicating with the through cavity of the tubular body 3131 is provided on the limiting platform 3132, the hollow tube 3133 is provided on the connection hole, and the infusion tube 314 penetrates through the hollow tube 3133.

[0053] Further, the outer wall of the tubular body 3131 is further provided with a first installation groove 31311, a second installation groove 31312, and a third installation groove 31313 for connecting sealing rings. A first sealing ring is provided in the first installation groove 31311, a second sealing ring is provided in the second installation groove 31312, and a third sealing ring is provided in the third installation groove 31313. Attached Figure 2 Among them, the above-mentioned first sealing ring, second sealing ring, and third sealing ring are not shown. The first sealing ring, second sealing ring, and third sealing ring cooperate with the through cavity of the first pipe fitting 311 to prevent liquid leakage.

[0054] Please refer to again Figure 4 , the infusion tube 314 includes: an infusion tube body 3141, a guiding head 3143 connected to the lower end of the infusion tube body 3141, and a liquid outlet 31412 provided on the outer wall of the lower part of the infusion tube body 3141. The infusion tube body 3141 is a tube body, and the guiding head 3143 is connected to the lower end of the tube body.

[0055] As Figure 5 shown, the outer wall of the infusion tube body 3141 is further provided with a hanging portion 31411. A fixing plate 316 is provided on the hanging portion 31411. The fixing plate 316 is divided into a first fixing plate 3161 and a second fixing plate 3162. The first fixing plate 3161 and the second fixing plate 3162 jointly enclose a hanging hole 31611 for supporting and fixing the hanging portion 31411. The first fixing plate 3161 and the second fixing plate 3162 are supported on the upper end of the first pipe fitting 311. Among them, a circular platform is further provided at the opening edge of the upper end of the tube body 3111 of the first pipe fitting 311. The first fixing plate 3161 and the second fixing plate 3162 are installed on the circular platform. The first fixing plate 3161 is further provided with a hollow hole 31612, and the second fixing plate 3162 is further provided with a hollow 31621. The reason for designing the fixing plate 316 in the form of a combination of the first fixing plate 3161 and the second fixing plate 3162 is mainly to facilitate disassembly, cleaning, and disassembly. When disassembling, only need to insert a tool into the hollow hole to remove the fixing plate 316, and then, the first pipe fitting 311 can be directly pulled out from the second pipe fitting 313, and further the infusion tube 314 can be pulled out from the hollow tube 3133, and finally each part can be cleaned or repaired. Compared with other existing fixing structures, this structure is ingeniously designed, simple in itself, convenient for disassembly and cleaning, and greatly improves production efficiency.

[0056] In this embodiment, the hanging portion 31411 is an annular groove recessed in the outer wall of the infusion tube body 3141. Of course, in other embodiments, the hanging portion 31411 may also be an annular end wall protruding from the outer wall of the infusion tube body 3141.

[0057] Specifically, the guiding head 3143 is a conical head, and a diversion head 3142 protrudes from the end face of the conical head. The diversion head 3142 is located in the through cavity of the infusion tube body 3141, and the bottom of the diversion head 3142 is higher than the lowest point of the liquid outlet 31412. The diversion head 3142 is in a pointed shape to prevent liquid from accumulating in the lower cavity of the infusion tube body 3141. The guiding head 3143 is used for quickly inserting into the container opening, and the end face of the guiding head 3143 is slightly larger than the lower end face of the hollow tube 3133. During assembly, the guiding head 3143 is hooked on the lower end face of the hollow tube 3133. A sealing ring 3144 is also provided at the liquid outlet 31412 of the infusion tube body 3141 for sealing the conical head and the lower end face of the hollow tube 3133.

[0058] Please refer to again Figure 2 It further includes a plastic head 315. A connection hole is provided on the plastic head 315, and the connection hole is inserted into the upper end of the infusion tube 314, and the plastic head 315 abuts against the first fixing plate 3161 and the second fixing plate 3162.

[0059] The working principle of the liquid filling head is briefly introduced as follows: When it is necessary to open the liquid outlet 31412, an external force is applied to the plastic head 315 (generally, the external infusion tube port end applies the pressure). At this time, the plastic head 35 acts on the first pipe fitting 311, and the first pipe fitting 311 compresses the spring 312, thereby pushing the lower end of the infusion tube 314 to extend downward, so that the liquid outlet 31412 is exposed from the hollow tube 3133. At this time, the liquid can be output from the liquid outlet 31412. On the contrary, when the external force is released, under the restoring force of the elastic member 312, the infusion tube 314 is pushed upward, thereby closing the liquid outlet 31412, and the outward transportation of the liquid stops.

[0060] The liquid filling head, through the cooperation of the first pipe fitting, the second pipe fitting and the elastic member, an external force is applied to the first pipe fitting, so that the lower end of the infusion tube extends out, exposing the liquid outlet, and the liquid is transported outward. When the external force is released, the infusion tube automatically rebounds and closes the liquid outlet. In addition, the first fixing plate and the second fixing plate are used to realize the fixed hooking of the infusion tube, which is convenient for disassembly, cleaning, and assembly. The overall structure of the filling head is simple, which can meet the needs of rapid production, and the control of the infusion volume is accurate and reliable.

[0061] The working process of the automatic filling equipment of this embodiment is as follows:

[0062] First of all, the first dial 12 of the loading and unloading mechanism 100 sequentially feeds containers such as glass bottles onto the card seat 43, and the card seat 43 rotates synchronously and controllably with the rotating shaft 51;

[0063] When the card seat 43 rotates a certain distance, while the card seat 43 rotates, it is guided by the guide ring 42 to move upward until the lower end of the hollow tube 3133 of the filling head 31 is inserted into the container.

[0064] When the card holder 43 rotates to the first paddle 33, the first paddle 33 pushes the swing handle to rotate, so that the switching valve opens. During the subsequent rotational stroke at one end, the filling head 31 injects liquid into the container, and during this process, the filling head 31 is kept in close contact with the opening of the container to prevent liquid from spilling.

[0065] When the card holder 43 continues to rotate to the second paddle 34, the second paddle 34 pushes the swing handle of the switching valve to rotate in the reverse direction. At this time, the switching valve closes and stops injecting liquid into the container. During this process, the rotational stroke corresponds to the capacity of the container, and the time is just right to complete one filling of the liquid.

[0066] Finally, when the card holder 43 moves to the guide plate 14, the guide plate 14 pushes out the already filled container to complete the discharging.

[0067] Compared with the prior art, in the automatic filling equipment of the present invention, the material storage mechanism, the filling head and the card holder mechanism are all set in a synchronous rotation mode. The whole equipment occupies a small space, and in cooperation with the loading and unloading mechanism, the loading, unloading and filling processes of the container are carried out synchronously, improving the filling efficiency and reducing the production cost.

[0068] The above only uses embodiments to further illustrate the technical content of the present invention to make it easier for readers to understand, but it does not mean that the implementation mode of the present invention is limited to this. Any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
