Abstract
Description
Technical Field
[0001] This utility model relates to the field of foaming agent dispensing technology, and in particular to a foaming agent dispensing device for footwear. Background Technology
[0002] Shoes are an essential item for everyone, and we all own a certain number of them. In particular, sneakers and canvas shoes can be considered shoes for all seasons. These shoes are comfortable to wear and do not cause blisters. The reason why they can provide such comfort is that foaming agents are added to the soles during the manufacturing process, which increases comfort.
[0003] A foaming agent dispensing device for footwear, disclosed in Chinese patent CN215283014U, includes a bracket and a dispensing tank fixedly mounted on the bracket. The dispensing tank has a dispensing port and an output pipe at its top. The dispensing port is sealed with a sealing cap. A discharge buffer is installed at the output end of the output pipe. A vertically arranged support shaft is installed inside the dispensing tank, and a piston is fixedly mounted on the top of the support shaft. A guide groove cooperating with the support shaft is provided in the middle of the bottom of the dispensing tank. A linear bearing cooperating with the support shaft is fixedly mounted in the guide groove. A support spring connects the bottom of the support shaft to the bottom of the guide groove. A high-pressure air source is connected to the bottom of the dispensing tank via a pressurization pipe, and a pressurization control valve is installed on the pressurization pipe.
[0004] When the existing foaming agent dispensing device is used, a discharge buffer is installed at the end of the output pipe so that the foaming agent pushes the buffer block away from the output pipe during dispensing, causing the foaming agent to be squeezed out from between the conical protrusion and the output pipe. However, when the foaming agent is output, it is sprayed outward 360 degrees from the output pipe, which causes the foaming agent to disperse and not concentrate, making it inconvenient to integrate and use.
[0005] To address the aforementioned problems, this utility model proposes a foaming agent dispensing device for footwear. Utility Model Content
[0006] To address the problems existing in the background art, this utility model proposes a foaming agent injection device for footwear.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a foaming agent dispensing device for footwear, comprising a dispensing tank, an output pipe fixedly connected to the side wall of the dispensing tank, a baffle plate limited and installed at one end of the output pipe away from the dispensing tank, a buffer block slidably and sealed inside the output pipe, a plurality of through holes uniformly and annularly opened on the baffle plate corresponding to the output port of the output pipe, a plurality of first grooves opened inside the buffer block, the first grooves being arranged corresponding to the through holes; a second groove is opened inside the output pipe at the position corresponding to the first groove; the second grooves are connected to the inside of the output pipe; a piston is provided for vertical movement limitation inside the dispensing tank.
[0008] Preferably, multiple guide sleeves are evenly fixedly installed on the outer wall of the output pipe around the axis of the output pipe. Each guide sleeve has a guide rod slidably installed on it. One end of the guide rod is fixedly connected to the baffle. The other end of the guide rod is fixedly connected to a stop block. A buffer spring is sleeved on the outside of the guide rod. One end of the buffer spring is fixedly connected to the stop block, and the other end of the buffer spring is fixedly connected to the guide sleeve.

[0011] Preferably, a pressurization pipe is fixedly connected to the bottom of the side wall of the filling tank. One end of the pressurization pipe extending into the filling tank has an air outlet, and the other end of the pressurization pipe is fixedly connected to a high-pressure air source. A pressurization control valve is installed on the outside of the pressurization pipe.
[0012] Preferably, a support frame is fixedly installed at the bottom of the filling tank.
[0013] Beneficial effects
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This foaming agent dispensing device for footwear uses a piston to squeeze the foaming agent. The pressure of the foaming agent pushes the buffer block, and under the elastic force of the buffer spring, it is evenly output.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0022] Please see Figure 1-3 This utility model provides a technical solution: a foaming agent filling device for footwear, including a filling tank 2, with a support frame 1 fixedly installed at the bottom of the filling tank 2.
[0023] A filling pipe is fixed to the upper end face of the filling tank 2, and a sealing cap 3 is installed at the top of the filling pipe.
[0024] An output pipe 4 is fixedly connected to the side wall of the filling tank 2, and a baffle 21 is installed at the end of the output pipe 4 away from the filling tank 2.
[0025] Specifically, multiple guide sleeves 16 are evenly fixedly installed on the outer wall of the output pipe 4 around its axis. Guide rods 15 are slidably installed on each guide sleeve 16, with one end of the guide rod 15 fixedly connected to the baffle 21. A stop block 18 is fixedly connected to the other end of the guide rod 15. A buffer spring 17 is sleeved on the outer side of the guide rod 15, with one end of the buffer spring 17 fixedly connected to the stop block 18 and the other end of the buffer spring 17 fixedly connected to the guide sleeve 16.
[0026] A buffer block 14 is slidably installed inside the output pipe 4. Multiple through holes 22 are evenly distributed in a ring on the baffle 21 corresponding to the output port of the output pipe 4. Multiple first grooves 19 are formed inside the buffer block 14, corresponding to the through holes 22. Second grooves 20 are formed inside the output pipe 4 at positions corresponding to the first grooves 19. The second grooves 20 communicate with the interior of the output pipe 4.
[0027] The internal vertical movement limit of the filling tank 2 is provided by a piston 5.
[0028] Specifically, a guide groove 7 is fixedly installed at the bottom of the filling tank 2. A linear bearing 8 is fixedly installed inside the guide groove 7. A support shaft 6 is slidably installed inside the linear bearing 8. The piston 5 is fixedly connected to the top of the support shaft 6. A support spring 9 is fixedly connected to the bottom of the support shaft 6. The bottom of the support spring 9 is fixedly connected to the bottom surface of the guide groove 7.
[0029] A pressurizing pipe 10 is fixedly connected to the bottom of the side wall of the filling tank 2. One end of the pressurizing pipe 10 extending into the interior of the filling tank 2 is provided with an air outlet 13. The other end of the pressurizing pipe 10 is fixedly connected to a high-pressure air source 11. A pressurizing control valve 12 is installed on the outside of the pressurizing pipe 10.
[0030] Working principle:
[0031] When using, open the sealing cap 3, add foaming agent into the injection tube, and then tighten the sealing cap 3 after filling.
[0032] When the pressurization control valve 12 is opened, the gas in the high-pressure gas source 11 is ejected from the gas outlet 13 through the pressurization pipe 10, increasing the gas pressure at the bottom of the piston 5, thereby pushing the piston 5 to move upward.
[0033] Since the support shaft 6 is restricted to vertical movement within the guide groove 7, the piston 5 can move smoothly up and down within the filling tank 2, and the support spring 9 provides cushioning when the support shaft 6 moves up and down.
[0034] Piston 5 squeezes the foaming agent in filling tank 2, and the foaming agent is squeezed into output pipe 4. The pressure continuously increases, and part of the foaming agent flows into the second groove 20, while part of the foaming agent pushes the buffer block 14 to move out of the output pipe 4. The buffer block 14 pushes the baffle 21 to move. Due to the elastic force of the buffer spring 17 on the baffle 21, the foaming agent can move evenly. The buffer block 14 and the baffle 21 are always in contact until the end of the first groove 19 in the buffer block 14 near the filling tank 2 is aligned with the end of the second groove 20 in the output pipe 4 away from the filling tank 2. At this time, the buffer spring 17 just reaches its maximum limit, and the buffer block 14 no longer moves outward. At this time, the pressure reaches equilibrium, and the foaming agent flows into the first groove 19 through the second groove 20 and is evenly output from the through hole 22.
[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
