Description

Technical Field

[0001] The invention relates to the technical field of production and processing of printing consumables, and in particular to ink bottle sealing processing equipment, a processing technology and an ink bottle. Background Art

[0002] During the printing process of the printer, corresponding printing consumables need to be used. Ink printers need to use printer ink bottles during the printing process to supply ink for the printing process.

[0003] Existing printer ink bottles generally consist of a bottle body, a bottle cover and a bottle outer cover. During the production process, in order to ensure the sealing of the ink bottle, a sealing circular film is welded between the bottle body and the bottle cover, and the opening of the bottle body is initially sealed by the sealing circular film. The sealing circular film needs to be broken during use. On the basis of the sealing circular film, the bottle cover and the bottle body are threadedly connected, and the bottle cover is fixed to the bottle body by the threaded connection. However, since there is a certain structural gap in the threaded connection, in order to enhance the sealing, a sealing ring is added between the lower end of the bottle cover and the bottle body through electromagnetic welding to prevent the bottle cover and the bottle body from rotating. In addition, the bottle outer cover is also threadedly connected to the bottle cover and a sealing ring is added through electromagnetic welding.

[0004] During the production and processing of the above-mentioned existing printer ink bottle, a series of steps are required, such as welding the sealing circular film, testing the sealing performance of the circular film, threading the bottle cover and the bottle body, and electromagnetic welding the sealing ring, which will make the overall processing equipment more complicated. Moreover, if the sealing circular film is not welded in place, it is very easy to cause ink leakage in the printer ink bottle. At the same time, the threaded connection between the bottle cover and the bottle body requires the use of a more precise clamping fixture, otherwise the threaded connection between the bottle body and the bottle cover will be loose, which will also cause the problem of ink leakage.

DETAILED DESCRIPTION

[0030] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0031] Refer to the instruction manual Figure 1-4 , an ink bottle sealing processing equipment is used in conjunction with an ink bottle for a printer. The ink bottle sealing processing equipment is provided with a conveying device for conveying the ink bottles. The conveying device adopts a conveyor belt. The ink bottles to be filled are conveyed to corresponding workstations one by one through the conveyor belt. At the same time, in order to better enable subsequent workstations to process the ink bottles, a bottle separation baffle 24 that can block the ink bottles one by one is provided at the starting position of the conveyor belt. The bottle separation baffle 24 can be inserted between two adjacent ink bottles.

[0032] A weighing and filling structure, a bottle cap placement structure and an ultrasonic welding structure 1 are sequentially arranged along the conveying direction of the ink bottle, wherein the weighing and filling structure is used to fill ink into the ink bottle, the bottle cap placement structure is used to place the bottle cap on the ink bottle that has been filled with ink, and at the same time the bottle cap is buckled on the ink bottle to cover the opening of the ink bottle, and the ultrasonic welding structure 1 applies an ultrasonic welding force to the ink bottle with the bottle cap placed thereon, and completes the sealing welding under the condition of ultrasonic vibration.

[0033] The ultrasonic welding structure 1 uses a relatively mature ultrasonic welding device. Since the contact area between the bottle cap and the bottle body 18 is small and the thickness between the bottle cap and the bottle body 18 is thin, the ultrasonic welding device is limited to a device that can generate an ultrasonic frequency of 40kHz to 60kHz.

[0034] The bottle cap placement structure includes a bottle cap loading assembly, a bottle body positioning assembly and a bottle cap transfer assembly. The bottle cap loading assembly is arranged on one side of the ink bottle conveying direction for conveying the ink bottle cap, the bottle body positioning assembly is arranged at a position perpendicular to the ink bottle conveying direction for fixing and positioning the ink bottle body, and the bottle cap transfer assembly is used to transfer the bottle cap at the bottle cap loading assembly and snap it to the ink bottle opening at the bottle body positioning assembly.

[0035] The bottle cap loading assembly adopts a vibrating loading plate and a loading lifting belt 25, which can lift the bottle cap in a lower position to the level of the equipment, and then move it to the opening of the ink bottle body 18 through the bottle cap transfer assembly.

[0036] The bottle cap transfer assembly includes a bottle cap clamp 2 and a transfer component. The bottle cap clamp 2 is used for grasping and placing ink bottle caps. The transfer component is used for moving the end of the bottle cap clamp 2. The transfer component includes a fixed plate 3, a concave groove, a rotating arm 5 and a supporting plate 6. The concave groove 4 is provided on the fixed plate 3 to provide a sliding track for the supporting plate 6. The rotating arm 5 is rotatably connected to the fixed plate 3 and is provided with a sliding groove 7. The supporting plate 6 is provided with an auxiliary shaft 8 whose end is located in the concave groove 4 and inserted into the sliding groove 7. The bottle cap clamp 2 is fixedly connected to the supporting plate 6.

[0037] The vertical cross-section of the concave groove 4 along the moving direction of the ink bottle is in a concave shape, with the concave notch facing the ink bottle. The positioning and guiding of the support plate 6 is achieved by setting the concave groove 4. A sliding groove 7 is provided on the rotating arm 5. In order for the support plate 6 to move along the concave groove 4, the rotating arm 5 provides corresponding power for the support plate 6.

[0038] The bottle cap clamp 2 here adopts an air-driven multi-claw fixed structure, including a fixed block 22, a plurality of limit claws 23 arranged around the center of the fixed block 22, and a connecting air path is opened at the ends of the plurality of limit claws 23, and the retraction and extension of the limit claws 23 are achieved by the positive and negative pressure of the gas.

[0039] In order to place the bottle cap more stably, a bottle body positioning assembly is provided. The bottle body positioning assembly includes positioning plates 9 arranged on both sides of the ink bottle conveying direction. One end of the two positioning plates 9 is fixedly connected via a two-way cylinder 10, and the output end of the two-way cylinder 10 is fixedly connected to the positioning plate 9 on the corresponding side.

[0040] The weighing and filling structure includes an ink filling machine 11, a weighing platform 12 and an ink bottle moving auxiliary component. The output end of the ink filling machine 11 is inserted into the ink bottle to fill the ink bottle. The weighing platform 12 is used in conjunction with the ink filling machine 11 for ink filling and weighing. The ink bottle moving auxiliary component is used to smoothly move the filled ink bottle.

[0041] The ink filling machine 11 is divided into two groups. The first group is rough filling. The ink filling machine 11 fills ink into the ink bottle through the ink outlet and stops when the liquid level in the ink bottle reaches 5 cm from the bottle mouth. The second group is fine filling. The ink filling machine 11 fills the liquid level from 5 cm to 1 cm from the bottle mouth.

[0042] In order to accurately achieve the filling position of the ink bottle liquid level, a weighing comparison is performed through a weighing platform 12 arranged under the ink filling machine 11.

[0043] The ink bottle moving auxiliary component includes a clamping plate 13, a driving motor 14 and a linear motor guide pair 15. The clamping plate 13 is arranged in parallel on both sides of the ink bottle conveying direction. The output end of the driving motor 14 is fixedly connected to a rotating shaft 16. Both ends of the rotating shaft 16 are provided with threads with opposite rotation directions. The rotating shaft 16 is threadedly connected to the clamping plate 13 on the corresponding side through a nut. The linear motor guide pair 15 is used to drive the driving motor 14 to move slowly along the ink bottle conveying direction.

[0044] An isosceles trapezoidal limiting groove 17 is provided on the clamping plate 13, and the ink bottle body 18 can be located in the limiting groove 17. The ink bottle filled with ink is limited and fixed by the limiting groove, and the moving stability of the linear motor guide pair 15 is used to ensure the smooth operation of the ink bottle during the movement.

[0045] In combination with the above processing equipment, a processing technology for sealing an ink bottle includes the following steps:

[0046] Step 1: filling ink and weighing: filling ink into the ink bottle by the ink filling machine 11, judging the ink filling degree by the weighing platform 12, and obtaining the filled ink bottle;

[0047] In step 1, the ink filling machine 11 is divided into two groups, the first group is for rough filling, and the second group is for fine filling. The ink bottle is smoothly moved between the first group and the second group through the ink bottle moving auxiliary component.

[0048] Step 2: Place and snap the bottle caps together. Use the ink bottle moving auxiliary assembly to smoothly move the ink bottles filled in step 1 to the bottle body positioning assembly one by one. Use the two-way cylinder 10 and the fixing plate 3 to clamp and fix the ink bottles. The bottle cap clamps 2 place the bottle caps on the ink bottles and snap them together to obtain the ink bottles with the bottle caps snapped on.

[0049] Step 3, ultrasonic welding, the ink bottle with the bottle cap obtained in step 2 is smoothly moved to the ultrasonic welding structure 1 through the ink bottle moving auxiliary component, the ultrasonic welding structure 1 acts on the bottle cap, and under the action of ultrasonic welding, the bottle cap is sealed and installed on the ink bottle to obtain a sealed ink bottle;

[0050] In step 3, the ultrasonic welding frequency is 40kHz or 60kHz.

[0051] Finally, the sealed ink bottle was subjected to a sealing test, and the sealing integrity of the sealed ink bottle was found to be 98%.

[0052] Refer to the instruction manual Figure 5 The ink bottle for a printer is different from the conventional ink bottle for a printer in that no welding film is required in the ink bottle, and the bottle cap of the ink bottle and the bottle body 18 do not need to be screwed together, so the bottle cap can be installed on the bottle body 18 more directly.

[0053] The ink bottle includes a bottle body 18 and a cover body 19. A stepped bearing surface is provided at the opening of the bottle body 18. The cover body 19 is also provided with an ultrasonic welding surface 21 that is in contact with the stepped bearing surface 20. The ultrasonic welding surface 21 on the cover body 19 is in contact with the bearing surface on the bottle body 18 and a certain ultrasonic welding force is applied, so that the cover body 19 and the bottle body 18 are sealed.

[0054] In summary, the present application changes the existing sealing process of the ink bottle, which reduces the number of sealing steps and improves the sealing integrity compared to the existing ink bottle sealing process of first pasting a round film after filling, then screwing the bottle cap, and finally electromagnetic welding.

[0055] When installing the bottle cap of the present application, due to the structural change of the ink bottle, there is no need to spirally rotate the cover body 19 and the bottle body 18, which reduces the complexity of the installation structure and can better realize and facilitate subsequent maintenance.
