Description

Technical Field

[0001] The invention relates to a ceramic tile processing device, in particular to an inkjet head of ceramic tile packaging equipment. Background Art

[0002] During the packaging process of ceramic tiles, it is necessary to print designated numbers or other identifications on the outer packaging of the ceramic tiles for subsequent classification and storage. For the outer packaging of ceramic tiles of different sizes or types, it is necessary to print numbers with different thicknesses of lines, so that the overall visual appearance of the ceramic tile outer packaging is clearer and more beautiful. The inkjet head of the printing device in the prior art generally changes the magnetism of the limit rod by energizing and de-energizing the coil, thereby achieving the movement of the ink blocking rod by absorbing or repelling the ink blocking rod, and then achieving the opening and closing of the ink outlet. In addition, the adjustment end of the limit rod in the prior art is connected to the shell of the inkjet head by a threaded structure. When adjusting the ink output, the position of the limit rod is adjusted by rotating the limit rod, thereby changing the distance between the limit end of the limit rod and the moving end of the ink blocking rod, so that the sliding distance of the ink blocking rod changes when power is turned on, thereby changing the gap between the tight end of the ink blocking rod and the ink outlet, and changing the ink output. However, this adjustment method has the following problems: when the limit rod rotates, it will produce relative movement with the sealing element, or drive the sealing element to rotate at the same time, resulting in a certain amount of friction between the sealing element and the limit rod or other components, thereby causing damage to the sealing element or even displacement, seriously affecting the sealing effect, and making it easy for ink leakage to occur. Summary of the Invention

[0003] The object of the present invention is to overcome the deficiencies of the prior art and to provide an inkjet head for a tile packaging device, which has a simple structure, is convenient for controlling and adjusting the inkjet amount, and has good sealing performance.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A inkjet head for ceramic tile packaging equipment, characterized in that it includes a shell, a coil arranged in the shell, an ink blocking rod and a limit rod; an ink storage chamber is provided in the shell, the ink storage chamber is connected to an ink supply device, and an ink outlet for inkjet is provided in the ink storage chamber; the coil is connected to a power supply, and the moving end of the ink blocking rod and the limiting end of the limit rod are both arranged in the coil; wherein, in a non-working state, a sliding gap is left between the moving end of the ink blocking rod and the limiting end of the limit rod, the abutting end of the ink blocking rod extends to the corresponding position of the ink outlet and blocks the ink outlet; the adjusting end of the limit rod extends outside the shell, and an elastic element is provided between the limit rod and the shell to always urge the limit rod to have a tendency to slide outward; an adjusting block is provided outside the shell to prevent the limit rod from sliding outward, the adjusting block is arranged corresponding to the adjusting end of the limit rod, and the adjusting block and the shell are locked to the shell by a locking connection structure.

[0006] The working principle of the inkjet head of the above-mentioned tile packaging equipment is as follows:

[0007] During operation, the power is turned on and the coil is energized, causing the magnetic property of the limiting rod arranged inside the coil to change. The limiting rod exerts an attracting force on the ink-blocking rod, causing the moving end of the ink-blocking rod to slide towards the limiting end of the limiting rod and the two to attract each other; at this time, the pressing end of the ink-blocking rod leaves the ink outlet of the ink storage cavity. Under the action of the ink supply device, the ink in the ink storage cavity is ejected through the ink outlet, thus achieving the purpose of inkjet printing. After the inkjet is completed, the power is disconnected and the coil is de-energized. The magnetic property of the limiting rod returns to its initial state, and the limiting rod exerts a repulsive force on the ink-blocking rod. The moving end of the ink-blocking rod leaves the limiting rod and slides to its initial position. The pressing end of the ink-blocking rod is pressed against the ink outlet under the repulsive force of the limiting rod, and the ink in the ink storage cavity no longer ejects. When it is necessary to adjust the ink output of the ink outlet, the position of the adjusting block is adjusted through the locking connection structure, specifically by moving it outward or inward along the extension direction of the limiting rod. Thus, under the elastic force of the elastic element or the pressure of the adjusting block, the limiting rod is driven to move outward or inward, realizing the increase or decrease of the sliding gap, achieving the purpose of changing the sliding distance of the ink-blocking rod, and further changing the gap between the pressing end of the ink-blocking rod and the ink outlet during operation, completing the adjustment of the ink output. Since during the adjustment process of the ink output, by changing the position of the adjusting block and combining with the elastic force of the elastic element, the limiting rod only moves in the length direction, avoiding the rotation of the limiting rod, thus avoiding damage to the sealing element, ensuring the sealing performance of the entire inkjet head, and preventing ink leakage.

[0008] In a preferred embodiment of the present invention, a connection block is provided at the adjustment end of the limiting rod. The connection block is larger than the limiting rod. The elastic element is arranged between the connection block and the housing, and the adjusting block is correspondingly arranged with the connection block.

[0009] Preferably, an open installation cavity is provided inside the housing. The connection block and the elastic element are arranged in the open installation cavity, and the connection block extends outside the housing.

[0010] Preferably, the connection block and the adjustment end of the limiting rod are connected through a threaded connection structure. Specifically, an internal threaded hole is provided at one end of the connection block corresponding to the adjustment end of the limiting rod, and a matching external thread is provided at the adjustment end of the limiting rod.

[0011] Preferably, the elastic element is a spring. The spring is sleeved on the limiting rod, and one end of the spring acts on the connection block, and the other end acts on the inner bottom surface of the open installation cavity.

[0012] In a preferred embodiment of the present invention, the locking connection structure includes a screw and a threaded hole. The threaded hole is provided on the housing, and the adjusting block is provided with a connection hole for the screw to pass through. After the screw passes through the connection hole, it is fitted and installed in the threaded hole of the housing.

[0013] Preferably, a groove is provided on the housing, and the groove is correspondingly arranged with the adjusting block.

[0014] In a preferred embodiment of the present invention, a guiding installation tube is further provided inside the housing, and the coil, the limiting rod, and the ink-blocking rod are all arranged in the guiding installation tube; one end of the guiding installation tube is communicated with the opening installation cavity, and the other end is communicated with the ink storage cavity.

[0015] In a preferred embodiment of the present invention, an ink-blocking head is provided at the pressing end of the ink-blocking rod. The ink-blocking head in this embodiment can be made of a flexible material or other materials with strong sealing performance.

[0016] In a preferred embodiment of the present invention, an ink supply tube is provided inside the housing. One end of the ink supply tube is communicated with the ink storage cavity, and the other end extends along the length direction of the housing and extends outside the housing; an ink supply connection head connected to the ink supply tube is provided outside the housing.

[0017] The present invention has the following beneficial effects compared with the prior art:

[0018] By adjusting the position of the adjusting block through the locking connection structure and cooperating with the elastic force of the elastic element, the present invention realizes the adjustment of the position of the limiting rod, so that the sliding gap between the limiting rod and the coating rod changes accordingly, thereby achieving the purpose of changing the sliding distance of the ink-blocking rod. Furthermore, the gap between the pressing end of the ink-blocking rod and the ink outlet during operation is changed, and finally the adjustment of the ink output is completed. During the whole adjustment process, by changing the position of the adjusting block and combining with the elastic force of the elastic element, the limiting rod only moves in the length direction, avoiding the rotation of the limiting rod, thereby avoiding the damage to the sealing element, ensuring the sealing performance of the whole inkjet head, and avoiding ink leakage.

[0022] See Figure 3 , a connecting block 6 is provided at the adjusting end of the limiting rod 9, and the connecting block 6 is larger in diameter than the limiting rod 9, and the elastic element is arranged between the connecting block 6 and the housing 1, and the adjusting block 3 is correspondingly arranged with the connecting block 6. By providing the connecting block 6 with a larger diameter, it is convenient for the installation of the elastic element, so that the elastic force of the elastic element can act fully on the connecting block 6, thereby realizing the acting tendency on the limiting block. At the same time, the connecting block 6 with a larger diameter is convenient for cooperating with the adjusting block 3, which is beneficial to improving the stability of the limit.

[0023] See Figure 3 , an open mounting cavity 7 is provided in the housing 1, the connecting block 6 and the elastic element are arranged in the open mounting cavity 7, and the connecting block 6 extends outside the housing 1. Through the setting of the open mounting cavity 7, the connecting block 6 and the elastic element can be embedded and arranged in the housing 1, and only one end of the connecting block 6 needs to extend outside the housing 1, making the structure of the entire inkjet head more compact and the appearance more beautiful.

[0024] See Figure 3 , the connecting block 6 and the adjusting end of the limiting rod 9 are connected through a threaded connection structure. Specifically, an internal threaded hole 5 is provided at one end of the connecting block 6 corresponding to the adjusting end of the limiting rod 9, and a matching external thread is provided at the adjusting end of the limiting rod 9. This can realize the detachable connection between the connecting block 6 and the adjusting end of the limiting rod 9, which is convenient for installation and disassembly, and the compression degree of the elastic element can be adjusted by adjusting the depth of the adjusting end of the limiting rod 9 embedded in the internal threaded hole 5 of the connecting block 6 for debugging.

[0025] See Figure 3, the elastic element is a spring 8, which is sleeved on the limiting rod 9, and one end of the spring 8 acts on the connecting block 6, and the other end acts on the inner bottom surface of the opening mounting cavity 7. Using the spring 8 as the elastic element has a simple structure and is convenient for installation.

[0026] See Figure 3 , the locking connection structure includes a screw (not shown in the figure) and a threaded hole 5. The threaded hole 5 is provided on the housing 1. The adjusting block 3 is provided with a connecting hole 4 for the screw to pass through. After the screw passes through the connecting hole 4, it is fitted and installed in the threaded hole 5 on the housing 1. There are two groups of the locking connection structures in this embodiment. The connecting holes 4 of the two groups of locking connection structures are respectively arranged at both ends of the adjusting block 3. Two threaded holes 5 are correspondingly arranged on the housing 1. The middle position of the adjusting block 3 is tightly pressed against the connecting block 6. When the ink output needs to be adjusted, by rotating the screw, changing the depth of the screw in the threaded hole 5 can change the position of the adjusting block 3, so that under the action of the elastic element, the position of the limiting rod 9 can be adjusted to realize the adjustment of the ink output. The locking connection structure can also be provided with multiple groups as needed.

[0027] See Figure 3 , the housing 1 is provided with a groove 14, which is correspondingly arranged with the adjusting block 3. Through the arrangement of the groove 14, the adjusting block 3 can be embedded in the groove 14, avoiding excessive protrusion on the housing 1, which is beneficial to making the whole structure more compact.

[0028] See Figure 3 , a guiding installation tube 13 is further arranged in the housing 1. The coil 10, the limiting rod 9 and the ink blocking rod 12 are all arranged in the guiding installation tube 13. One end of the guiding installation tube 13 is communicated with the opening mounting cavity 7, and the other end is communicated with the ink storage cavity 15. Through the arrangement of the guiding installation tube 13, it is convenient for the arrangement of the coil 10, the limiting rod 9 and the ink blocking rod 12, and makes the sliding of the ink blocking rod 12 more stable.

[0029] See Figure 3 , the pressing end of the ink blocking rod 12 is provided with an ink blocking head 16. The ink blocking head 16 in this embodiment can be made of a flexible material or other materials with strong sealing performance. Through the arrangement of the ink blocking head 16, it is beneficial to effectively seal and block the ink outlet 17 in the ink storage cavity 15, avoiding ink leakage in the non-working state.

[0030] See Figure 4, an ink supply tube 18 is provided inside the housing 1. One end of the ink supply tube 18 is connected to the ink storage chamber 15, and the other end extends along the length direction of the housing 1 and extends outside the housing 1; an ink supply connector 2 connected to the ink supply tube 18 is provided outside the housing 1. Through the arrangement of the ink supply tube 18, the connection between the ink supply device and the ink storage chamber 15 is made more convenient, and the connection end of the ink supply device and the ink storage chamber 15 is far away from the ink outlet 17, which is beneficial to the ejection of ink. In this embodiment, the ink supply tube 18 includes two shunt tubes and a main tube; the main tube is connected to the ink supply connector 2; one ends of the two shunt tubes are both connected to the main tube, and the other ends are both connected to the ink storage chamber 15.

[0031] See Figures 1 - 4 , the working principle of the inkjet head of the tile packaging equipment in this example is:

[0032] During operation, the power is turned on, the coil 10 is energized, so that the magnetism of the limiting rod 9 arranged inside the coil 10 changes. The limiting rod 9 has an attracting effect on the ink blocking rod 12, making the moving end of the ink blocking rod 12 slide towards the limiting end of the limiting rod 9 and attracting each other; at this time, the abutting end of the ink blocking rod 12 leaves the ink outlet 17 of the ink storage chamber 15. Under the action of the ink supply device, the ink in the ink storage chamber 15 is ejected through the ink outlet 17, so as to achieve the purpose of inkjet printing; after the inkjet is completed, the power is turned off, the coil 10 is de-energized, the magnetism of the limiting rod 9 returns to the initial state, the limiting rod 9 has a repulsive effect on the ink blocking rod 12, the moving end of the ink blocking rod 12 leaves the limiting rod 9 and slides to the initial position, and the abutting end of the ink blocking rod 12 abuts against the ink outlet 17 under the repulsive effect of the limiting rod 9, and the ink in the ink storage chamber 15 no longer ejects. When it is necessary to adjust the ink ejection amount of the ink outlet 17, the position of the adjusting block 3 is adjusted through the locking connection structure, specifically moving outward or inward along the extension direction of the limiting rod 9. Thus, under the elastic force of the elastic element or the pressure of the adjusting block 3, the limiting rod 9 is driven to move outward or inward, realizing the increase or decrease of the sliding gap 11, achieving the purpose of changing the sliding distance of the ink blocking rod 12, and further changing the gap between the abutting end of the ink blocking rod 12 and the ink outlet 17 during operation to complete the adjustment of the ink ejection amount. Since during the adjustment process of the ink ejection amount, by changing the position of the adjusting block 3 and combining with the elastic force of the elastic element, the limiting rod 9 only moves in the length direction, avoiding the rotation of the limiting rod 9, thereby avoiding the damage to the sealing element, ensuring the sealing performance of the entire inkjet head, and avoiding ink leakage.
