Description

Technical Field

[0001] This utility model belongs to the field of bottle cap production technology, and more specifically, relates to a bottle cap assembly equipment. Background Technology

[0002] Some spray bottle caps include a cap body and a plug. The cap body has a hollow spray tube at the top, and the top of the spray tube has a protrusion. The side wall of the protrusion has a discharge port. The plug is fitted onto the top of the spray tube and has an opening at the top. The plug can move up and down. When the protrusion is embedded in the opening, it is in a closed state, and the plug will close the discharge port, preventing the spray tube from spraying material. When the protrusion is not embedded in the opening, it is in an open state, and the discharge port will connect with the opening, allowing the spray tube to spray material.

[0003] The nozzle and cap are molded as one piece, but the plug needs to be mechanically assembled onto the nozzle. In practice, after assembly, the sealing condition needs to be checked to ensure that the quality of the spray bottle cap is up to standard. This step is basically done by manual sampling, which is inefficient and inevitably some defective products will enter the market. Utility Model Content

[0004] The main purpose of this invention is to provide a bottle cap assembly device that allows for sealing tests after assembly, thereby improving efficiency.

[0005] According to a first aspect of the present invention, a bottle cap assembly device is provided, including a first base, a second base, a first cylinder and a second cylinder provided on the first base, and a first material conveying channel provided on the first base, wherein the length direction of the first material conveying channel is a first direction and the width direction of the first material conveying channel is a second direction.

[0006] The first cylinder is connected to the first material conveying channel, which is equipped with an assembly station. One end of the assembly station along the second direction has a feed inlet, and the other end along the second direction has a discharge outlet. Both the feed inlet and the discharge outlet are connected to the material conveying channel. The feed inlet is connected to an external cover conveying device, which conveys the covers one by one to the assembly station. The first cylinder is used to push the covers in the assembly station along the first material conveying channel.

[0007] The second base is located above the first material conveying channel. The second base has a second material conveying channel. The bottom of the second material conveying channel has a first through hole, and the top of the second material conveying channel has a second through hole. The first through hole and the second through hole are opposite to each other and are opposite to the assembly station. An external plug conveying device is connected to the second material conveying channel to convey plugs one by one into the second material conveying channel. The plugs of the second material conveying channel fall onto the cover of the assembly station through the first through hole.

[0008] The second cylinder is located above the second base. The output end of the second cylinder is provided with a pressure tube. Under the drive of the second cylinder, the pressure tube can pass through the first through hole and the second through hole to press the plug onto the cover. The inner diameter of the pressure tube is larger than the diameter of the plug opening, and the outer diameter of the pressure tube is smaller than the outer diameter of the plug.

[0009] The pressure pipe is connected to the air pressure detection module, and the bottom of the assembly station is provided with an air inlet. The air inlet is connected to an air supply unit for venting air into the interior of the cover in the assembly station.

[0010] In the bottle cap assembly equipment described above, the bottom of the pressure tube is provided with an annular rubber ring, which is coaxial with the pressure tube.

[0011] In the bottle cap assembly equipment described above, the air pressure detection module includes an adapter block and an air pressure gauge. The adapter block is fixed to the output end of the second cylinder. The pressure tube is inserted into the adapter block. A first air pipe is connected to the adapter block. The first air pipe connects the inside of the pressure tube to the air pressure gauge.

[0012] In the bottle cap assembly equipment described above, a third material conveying channel is provided on the first base, the third material conveying channel is connected to the inlet, and the external cap conveying equipment is connected to the third material conveying channel.

[0013] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0014] In this invention, the cover body is transported to the assembly station, and the plug falls onto the cover body through the first through hole. Under the action of the pressure tube, the plug can be pressed tightly onto the cover body, completing the assembly. At this time, the opening of the plug is blocked by the protrusion of the cover body. Since the pressure tube presses on the plug, and the inner diameter of the pressure tube is larger than the diameter of the plug opening, the inner cavity of the pressure tube is connected to the opening. At this time, gas is output through the gas supply unit, and the gas enters the interior of the cover body through the air inlet. If the seal between the plug and the cover body is not good, gas will leak into the inner cavity of the pressure tube, and the gas pressure detection module can detect the leak. If the product is deemed unqualified, the first cylinder will not activate. Once the next cover enters the assembly station, the unqualified product can be pushed out of the discharge port and fall into the waste bin. If the plug and cover have a good seal, the air pressure detection module will not detect a leak and will determine the product is qualified. The first cylinder will then activate, allowing the qualified product to move along the first conveying channel and leave the assembly station. Then, the next cover can enter the assembly station to continue assembly. This allows for direct sealing testing after cover assembly, greatly improving efficiency and accuracy.

[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0024] Reference Figures 1 to 4 As shown, a bottle cap assembly device includes a first base 1, a second base 2, a first cylinder 3 and a second cylinder 4 on the first base 1, and a first material conveying channel 11 on the first base 1. The length direction of the first material conveying channel 11 is a first direction, and the width direction of the first material conveying channel 11 is a second direction.

[0025] The first cylinder 3 is connected to the first material conveying channel 11. The first material conveying channel 11 is provided with an assembly station 111. One end of the assembly station 111 along the second direction is provided with a feed inlet 112, and the other end of the assembly station 111 along the second direction is provided with a discharge outlet 113. Both the feed inlet 112 and the discharge outlet 113 are connected to the material conveying channel. The feed inlet 112 is connected to an external cover conveying device, which conveys the covers one by one into the assembly station 111. The first cylinder 3 is used to push the covers in the assembly station 111 to move along the first material conveying channel 11.

[0026] The second base 2 is located above the first base 1. The second base 2 is provided with a second material conveying channel 21. The bottom of the second material conveying channel 21 is provided with a first through hole 22, and the top of the second material conveying channel 21 is provided with a second through hole 23. The first through hole 22 and the second through hole 23 are opposite to each other. The first through hole 22 is opposite to the assembly station 111. An external plug conveying device is connected to the second material conveying channel 21 to convey plugs one by one into the second material conveying channel 21. The plugs of the second material conveying channel 21 fall onto the cover of the assembly station 111 through the first through hole 22.

[0027] The second cylinder 4 is located above the second base 2. The output end of the second cylinder 4 is provided with a pressure tube 41. Under the drive of the second cylinder 4, the pressure tube 41 can pass through the first through hole 22 and the second through hole 23 to press the plug onto the cover. The inner diameter of the pressure tube 41 is larger than the diameter of the plug opening, and the outer diameter of the pressure tube 41 is smaller than the outer diameter of the plug.

[0028] The pressure pipe 41 is connected to the air pressure detection module 5. The bottom of the assembly station 111 is provided with an air inlet 6. The air inlet 6 is connected to an air supply unit (not shown in the figure) for venting air into the inside of the cover in the assembly station 111.

[0029] During operation, the external cover conveying device transports the cover to assembly station 111, and the external plug conveying device transports the plug to the second material conveying channel 21. The plug then gradually moves and falls onto the cover through the first through-hole 22. Under the action of the pressure pipe 41, the plug is pressed tightly onto the cover, completing the assembly. At this time, the opening of the plug is blocked by the protrusion of the cover. Because the pressure pipe 41 presses against the plug, and the inner diameter of the pressure pipe 41 is larger than the diameter of the plug opening, the inner cavity of the pressure pipe 41 is connected to the opening. At this point, gas is output through the air supply unit, and the gas enters the interior of the cover through the air inlet 6. If the seal between the plug and the cover is poor, gas will leak into the pressure pipe 41. In the cavity, the air pressure detection module 5 can detect air leakage and determine that the product is unqualified. In this case, the first cylinder 3 will not activate, and after the next cover enters the assembly station 111, the unqualified product can be pushed out from the discharge port 113 and fall into the waste box. If the plug and the cover have good sealing performance, the air pressure detection module 5 will not detect air leakage and will determine that the product is qualified. The first cylinder 3 will activate, allowing the qualified product to move along the first material conveying channel 11 and leave the assembly station 111. Then, the next cover can enter the assembly station 111 and continue assembly. In this way, the sealing test can be performed directly after the cover assembly is completed, which greatly improves efficiency and detection accuracy.

[0030] In this embodiment, the width of the second material conveying channel 21 is adapted to the outer diameter of the plug, ensuring that after the plug enters the second material conveying channel 21, it will move along the second material conveying channel 21. As the plug enters the second material conveying channel 21, the plug will push the plug to move, thereby causing the plug to fall out of the first through hole 22.

[0031] In this embodiment, a third cylinder can be installed on the second base 2. The output end of the third cylinder is provided with a first baffle. The second base 2 is provided with a first notch for the first baffle to enter and exit the second material conveying channel 21, and is equipped with a sensor to detect whether a plug enters the first through hole 22. When a plug is detected to have entered the first through hole 22, the third cylinder will drive the first baffle to extend into the second material conveying channel 21 to prevent other plugs from entering the first through hole 22. After the bottle cap is inspected at the assembly station 111, the third cylinder will drive the first baffle to leave the second material conveying channel 21.

[0032] In this embodiment, a third material conveying channel 114 is provided on the first base 1. The third material conveying channel 114 is connected to the inlet 112. An external cover conveying device is connected to the third material conveying channel 114. The width of the third material conveying channel 114 is adapted to the maximum outer diameter of the cover. The external cover conveying device conveys the covers one by one into the third material conveying channel 114. The cover will push the cover to move. The cover can only move along the third material conveying channel 114 and pass through the inlet 112 one by one into the assembly station 111.

[0033] In this embodiment, a fourth cylinder can be installed on the frame. The output end of the fourth cylinder is equipped with a second baffle. The first base block is provided with a second notch for the second baffle to enter and exit the third material conveying channel 114, and is equipped with a sensor to detect whether a cap enters the feed inlet 112. When a cap is detected to have entered the feed inlet 112, the fourth cylinder will drive the second baffle to extend into the third material conveying channel 114 to prevent other caps from entering the feed inlet 112. After the bottle cap is detected at the assembly station 111, the fourth cylinder will drive the second baffle to leave the third material conveying channel 114.

[0034] In this embodiment, both the external plug conveying device and the external cover conveying device utilize a vibratory feeder to ensure that the plug and cover are conveyed to the predetermined position in the correct posture.

[0035] In this embodiment, the bottom of the pressure tube 41 is provided with an annular rubber ring. The annular rubber ring is coaxial with the pressure tube 41 and can contact the plug, thereby improving the sealing effect between the pressure tube 41 and the plug and ensuring that the air pressure detection module 5 can detect when the plug opening leaks air.

[0036] In this embodiment, the air pressure detection module 5 includes an adapter block 51 and an air pressure gauge 52. The adapter block 51 is fixed to the output end of the second cylinder 4. The pressure tube 41 is inserted into the adapter block 51. A first air tube is connected to the adapter block 51. The first air tube connects the inside of the pressure tube 41 to the air pressure gauge 52. If the plug opening leaks air, the air pressure gauge 52 will show a significant change. The sealing performance is determined by detecting the range of air pressure changes.

[0037] In this embodiment, the gas supply unit includes a second gas pipe and a gas pump. The second gas pipe is connected to the air inlet 6 and the gas pump, and the gas is generated by the gas pump.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
