Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printing, in particular to a positioning device for an inkjet printing device and the inkjet printing device. Background Art

[0002] During the long-term use of an inkjet printing device, the channels need to be maintained from time to time. Most of the existing channels are movable channels. For example, a ceramic tile decoration device with clear decoration effect disclosed in the patent application No. CN202020986084.1 has the above-mentioned structure, which is a common movable channel structure. It can move and has the characteristic of convenient maintenance. However, after the maintenance is completed, it needs to be reset. Currently, maintenance personnel usually judge whether the reset is completed based on experience. During the judgment process, the machine needs to reprint a color registration chart to judge whether the reset is completed, which may lead to inaccurate judgment, wasting manpower and material resources and affecting the continuation of work.

[0003] Therefore, the prior art lacks an inkjet printing device that can quickly complete positioning for convenient reset. Summary of the Utility Model

[0004] In view of the above defects or improvement requirements of the prior art, the present utility model provides a positioning device for an inkjet printing device and the inkjet printing device, aiming to provide a positioning device for an inkjet printing device and the inkjet printing device, thereby solving the technical problem that the judgment during the reset process is inaccurate due to relying on experience. The detailed technical solution of the present utility model is as follows.

[0005] The present utility model protects a positioning device for an inkjet printing device, including a first positioning mechanism connected to the channel body, an observation part and a sensing part connected to the connection platform. When the channel body is connected to the connection platform and located at a preset position, the first positioning mechanism abuts against the sensing part.

[0006] Preferably, the first positioning mechanism includes an adjusting micrometer head. A connecting seat is connected to the front end of the top of the channel body, and the adjusting micrometer head is rotatably connected to the connecting seat.

[0007] Preferably, the positioning device further includes a knob and a locking bolt connected to the knob. The knob is rotatably connected to the connecting seat, and a threaded hole is correspondingly formed in the front end of the connection platform. The locking bolt is detachably threadedly connected to the threaded hole.

[0008] Preferably, the sensing part is in a boss structure.

[0009] Preferably, the observation part is a micrometer. When the channel body is connected to the connection platform and located at a preset position, the probe of the observation part abuts against the connection seat.

[0010] Preferably, the sensing part is a pressure sensor.

[0011] Preferably, the observation part is a pressure gauge electrically connected to the sensing part.

[0012] Preferably, the positioning device further includes a buffer mechanism. The buffer mechanism is connected to the front end of the connection platform, and a buffer groove is correspondingly and adaptively formed on the connection seat. When the channel body is connected to the connection platform and located at a preset position, the buffer mechanism abuts against the inner wall of the buffer groove.

[0013] Preferably, the positioning device further includes a second positioning mechanism. A connection bracket is connected to the rear end of the connection platform, and the second positioning mechanism is connected to the connection bracket;

[0014] When the channel body is connected to the connection platform and located at a preset position, the second positioning mechanism abuts against the rear end of the channel body.

[0015] The present invention also protects an inkjet printing device including the positioning device.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) Based on the cooperation and abutment of the first positioning mechanism and the sensing part, when the channel body is connected to the connection platform and located at a preset position, a corresponding reading will be displayed on the observation part, thus facilitating quick reset.

[0018] (2) The present invention fixes the channel body through a knob, a locking bolt, and a threaded hole. At the same time, with the cooperation of the first positioning mechanism, the sensing part, and the observation part, it is convenient and fast to set the feed amount of the corresponding channel body at the preset position, so as to quickly reset after each maintenance. At the same time, it can also avoid the situation that when the observation part is integrated into the knob, if the channel body is stretched out for maintenance, accidentally touching the knob will cause the reading on the observation part to change, resulting in inaccurate subsequent readings and inability to reset.

[0019] (3) The present invention also performs pre-positioning through the second positioning mechanism and provides a limit position, and cooperates with the first positioning mechanism to complete the multi-degree-of-freedom locking of the channel body. Description of the Drawings

[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, this embodiment specifically protects a positioning device for an inkjet printing device, including a first positioning mechanism connected to the channel body 10, an observation part 21 and a sensing part 22 connected to the connection platform 20. When the channel body 10 is connected to the connection platform 20 and is located at a preset position, the first positioning mechanism abuts against the sensing part 22.

[0029] Specifically, the preset position is the working position of the channel body 10 in the working state, that is, the position where precise inkjet printing can be continuously performed on the printing target. This working position has been debugged and set before the inkjet printing device leaves the factory. At the same time, there will be corresponding preset readings on the observation part 21;

[0030] It should be noted that the connection between the connection platform 20 and the channel body 10 is realized by a slide rail and slider structure 30 to achieve a sliding connection in the horizontal direction, so that the channel body 10 can be quickly pulled out when maintenance is required and quickly pushed back after the maintenance is completed. Figure 1 The S direction in [description] is the sliding direction of the channel body 10. When the channel body 10 needs to be maintained, pulling out the channel body 10 is the maintenance state.

[0031] As a preferred specific embodiment, the first positioning mechanism includes an adjusting micrometer head 41. A connecting seat 11 is connected to the front end of the top of the channel body 10, and the adjusting micrometer head 41 is rotatably connected to the connecting seat 11.

[0032] As a preferred embodiment, the positioning device further includes a knob 51 and a locking bolt 52 connected to the knob 51. The knob 51 is rotatably connected to the connecting seat 11, and a threaded hole 23 is correspondingly formed in the front end of the connecting platform 20, and the locking bolt 52 is detachably threadedly connected to the threaded hole 23.

[0033] As one of the preferred embodiments, the sensing part 22 is a boss structure.

[0034] As a preferred specific embodiment, the observation part 21 is a dial indicator. When the channel body 10 is connected to the connecting platform 20 and located at a preset position, the probe of the observation part 21 abuts against the connecting seat 11.

[0035] Through the above design, at this time, the observation part 21 and the adjusting micrometer head 41 are arranged in a staggered manner, the connecting seat 11 is close to the connecting platform 20, and at the same time, when the adjusting micrometer head 41 abuts against the sensing part 22 first, and then the connecting seat 11 contacts the probe of the observation part 21 to form a reading on the observation part 21. When the reading on the observation part 21 is the preset reading, that is, the reset of the channel body 10 is completed. At this time, the adjusting micrometer head 41 and the sensing part 22 with a boss structure are used to shorten the detection stroke, so as to cooperate with the locking bolt 52 to complete the reset positioning work.

[0036] As one of the preferred embodiments, the sensing part 22 is a pressure sensor.

[0037] As a preferred specific embodiment, the observation part 21 is a pressure gauge electrically connected to the sensing part 22.

[0038] With the above design, the differential head 41 is adjusted to contact the sensing part 22 first at this time. The pressure change forms an electrical signal, which is then fed back to the pressure gauge and forms a corresponding reading. When the reading on the observation part 21 is the preset reading, it means that the reset of the channel body 10 is completed. The advantage of this design is that the sensing part 22 and the observation part 21 are electrically connected, and the observation part 21 can be set at any convenient position for observation, so that the channel body 10 and the connection platform 20 can be designed more diversely.

[0039] It should be noted that the pressure gauge and the pressure sensor are both common technical solutions in the prior art, and their specific principles and structures will not be elaborated here.

[0040] As a preferred embodiment, the positioning device further includes a buffer mechanism 24. The buffer mechanism 24 is connected to the front end of the connection platform 20. A buffer groove 12 is correspondingly provided on the connection seat 11 in an adapted manner. When the channel body 10 is connected to the connection platform 20 and is in the preset position, the buffer mechanism 24 abuts against the inner wall of the buffer groove 12.

[0041] The buffer mechanism 24 is used to generate a damping feeling when the locking bolt 52 is screwed into the threaded hole 23 and is about to approach the sensing part 22, so that the maintenance personnel can clearly sense that it is about to reach the preset position, thereby slowing down the rotation speed of the knob 51 to avoid exceeding the preset position.

[0042] The specific buffer mechanism 24 can be a buffer or a damper, etc., which are common structures in the prior art. Specifically, it can be a spring or an oil buffer, or a technical solution that uses the same principle but different media to achieve the buffer damping effect, such as a structure that uses gas as the medium to achieve the air pressure buffer effect. Among them, the spring and the oil buffer are common technical solutions in the prior art, and their specific structures and principles will not be elaborated here. The structure that can achieve the air pressure buffer effect can be implemented by referring to the oil buffer and will not be elaborated here.

[0043] As Figure 6 shown, as a preferred embodiment, the positioning device further includes a second positioning mechanism 60. A connection bracket 25 is connected to the rear end of the connection platform 20, and the second positioning mechanism 60 is connected to the connection bracket 25;

[0044] When the channel body 10 is connected to the connection platform 20 and is in the preset position, the second positioning mechanism 60 abuts against the rear end of the channel body 10.

[0045] Specifically, the second positioning mechanism 60 can be a conical structure or a cylindrical structure. Correspondingly, in order to increase the positioning accuracy, a groove (not shown in the figure) is correspondingly provided on the rear end of the channel body 10, and the second positioning mechanism 60 can be embedded into the groove to complete the primary positioning of the channel.

[0046] This embodiment also protects an inkjet printing device, including a positioning device.

[0047] Working process:

[0048] When maintenance is required, by rotating the knob 51, the locking bolt 52 is screwed out of the threaded hole 23, thereby releasing the fixed connection relationship between the channel body 10 and the connection platform 20, so that the channel body 10 can be pulled out along the length direction of the slide rail and maintained;

[0049] After the maintenance work is completed, the channel body 10 is pushed back along the length direction of the track, and first abuts against the second positioning mechanism 60 to complete the initial positioning. Then, the knob 51 is rotated in the reverse direction to screw the locking bolt 52 into the threaded hole 23. When the channel body 10 is about to reach the preset position, the buffer mechanism 24 abuts against the inner wall of the buffer groove 12 first to generate a damping feeling. After the maintenance personnel feel the damping feeling, they slow down the rotation speed of the knob 51 and observe the observation part 21. Until the first positioning mechanism abuts against the sensing part, the reading of the observation part 21 changes, and a preset reading appears on the observation part 21 after continuous rotation. At this time, stop rotating the knob 51, and the channel body 10 is reset.

[0050] Those skilled in the art can easily understand that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
