[0005] The existing technology described above allows for the use of two or more suction heads to pick up multiple labels, but the number of suction heads is fixed during use and cannot be increased or decreased according to the number of labels. Therefore, we need a labeling machine with a quick-change suction head structure. Utility Model Content

[0006] The purpose of this invention is to provide a quick-change suction head structure for a labeling machine, so as to solve the problem mentioned in the background art that the number of suction heads is fixed and cannot be increased or decreased according to the number of labels.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a quick-change suction head structure for a labeling machine, including a mounting plate, a mounting base fixedly connected to one end of the mounting plate, and an mounting groove provided on the inner wall of the mounting base. An mounting block is fixedly connected to the inner wall of the mounting groove by bolts, and a fixing rod is fixedly connected to the bottom of the mounting block. An installation component is provided at one end of the fixing rod.

[0008] The mounting assembly includes a fixing block, and a T-slot is provided on one side of the fixing block. A first threaded hole is provided on the top of the fixing block. A T-block is fixedly connected to the other side of the fixing block, and a second threaded hole is provided on the top of the T-block. A fastening bolt is provided on the top of the fixing block, and a suction head assembly is provided on the outer wall of the fixing block.

[0009] The suction head assembly includes a circular groove, and a sliding rod is slidably connected to the inner wall of the circular groove. One end of the sliding rod is fixedly connected to a limit block, and a spring is provided on the outer wall of the sliding rod. The other end of the sliding rod is fixedly connected to a suction head seat, and an air inlet pipe is provided on the outer wall of the suction head seat. A threaded groove is opened on the inner wall of the suction head seat, and a sealing gasket is provided on the inner wall of the threaded groove. A threaded head is threadedly connected to the inner wall of the threaded groove, and a suction head body is fixedly connected to one end of the threaded head. A circular through hole is opened on the inner wall of the suction head body.

[0010] Preferably, the inner wall shape and size of the mounting groove match the outer wall shape and size of the mounting block, and the inner wall of the mounting groove fits into the outer wall of the mounting block.

[0011] Preferably, the inner wall shape and size of the T-slot match the outer wall shape and size of the T-block, and the inner wall of the T-slot fits into the outer wall of the T-block.

[0012] Preferably, the fixing block and the T-block are fixed together by fastening bolts, and one end of the fastening bolt is threaded through the first threaded hole and extends into the second threaded hole for connection.

[0013] Preferably, the number of circular grooves is four, and two circular grooves form a group, with the two groups of circular grooves symmetrically opened on the fixed block.

[0014] Preferably, one end of the sliding rod passes through the spring and the circular groove and is connected to the suction head seat, and the outer wall of the sliding rod is in contact with the inner wall of the circular groove.

[0015] Preferably, the suction head seat forms a threaded structure with a threaded groove and a threaded head, and one end of the threaded head extends into the threaded groove for connection.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] First, this utility model is equipped with a fixing block, a T-slot, a first threaded hole, a T-block, a second threaded hole, and a fastening bolt. Through the cooperation of the T-slot and the T-block, the fixing block can be easily added or removed. When it is necessary to increase the number of suction heads, the T-block on the new fixing block is slid into the T-slot of the existing fixing block, and then the fastening bolt is passed through the first threaded hole and the second threaded hole to fix it, thus completing the addition of the suction head assembly. Conversely, by unscrewing the fastening bolt and sliding out the corresponding fixing block, the number of suction heads can be reduced.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4As shown, a quick-change suction head structure for a labeling machine includes a mounting plate 1, a mounting base 2 fixedly connected to one end of the mounting plate 1, and a mounting groove 3 provided on the inner wall of the mounting base 2. A mounting block 4 is fixedly connected to the inner wall of the mounting groove 3 by bolts, and a fixing rod 5 is fixedly connected to the bottom of the mounting block 4. A mounting component 6 is provided at one end of the fixing rod 5.

[0026] The mounting component 6 includes a fixing block 601, and a T-slot 602 is provided on one side of the fixing block 601. A first threaded hole 603 is provided on the top of the fixing block 601. A T-block 604 is fixedly connected to the other side of the fixing block 601, and a second threaded hole 605 is provided on the top of the T-block 604. A fastening bolt 606 is provided on the top of the fixing block 601, and a suction head assembly 7 is provided on the outer wall of the fixing block 601.

[0027] The suction head assembly 7 includes a circular groove 701, and a sliding rod 702 is slidably connected to the inner wall of the circular groove 701. One end of the sliding rod 702 is fixedly connected to a limit block 703, and a spring 704 is provided on the outer wall of the sliding rod 702. The other end of the sliding rod 702 is fixedly connected to a suction head seat 705, and an air inlet pipe 706 is provided on the outer wall of the suction head seat 705. A threaded groove 707 is opened on the inner wall of the suction head seat 705, and a sealing gasket 708 is provided on the inner wall of the threaded groove 707. A threaded head 709 is threadedly connected to the inner wall of the threaded groove 707, and a suction head body 710 is fixedly connected to one end of the threaded head 709. A circular through hole 711 is opened on the inner wall of the suction head body 710.

[0028] Through the above technical solution, the T-slot 602 and T-block 604 can easily increase or decrease the number of fixing blocks 601. When it is necessary to increase the number of suction heads, slide the T-block 604 on the new fixing block 601 into the T-slot 602 of the existing fixing block 601, and then fix it by passing the fastening bolt 606 through the first threaded hole 603 and the second threaded hole 605. Conversely, unscrewing the fastening bolt 606 and sliding out the corresponding fixing block 601 will reduce the number of suction heads. It can be flexibly adjusted according to the number of labels, meeting diverse production needs and improving the versatility of the equipment. The suction head body 710 is threadedly connected to the threaded groove 707 of the suction head seat 705 through the threaded head 709, and the sealing gasket 70 is set. 8. To ensure a tight seal, when the suction head body 710 is worn, damaged, or needs to be replaced with a different type of suction head to adapt to different labels, simply unscrew the suction head body 710 and replace it with a new suction head body 710 with a suitable threaded head 709. The operation is simple and quick, without complicated tools and steps, shortening the replacement time and improving production efficiency. Through the sliding rod 702 sliding in the circular groove 701, in conjunction with the action of the spring 704, the suction head body 710 has a certain buffering capacity when contacting the label and the target object. This buffering effect can prevent rigid collisions between the suction head body 710 and the label or target object, protecting both the suction head body 710 and the label, and ensuring close contact between the suction head body 710 and the label, thus ensuring stable adsorption effect.

[0029] Specifically, the inner wall shape and size of the mounting groove 3 match the outer wall shape and size of the mounting block 4, and the inner wall of the mounting groove 3 fits into the outer wall of the mounting block 4.

[0030] With the above technical solution, the mounting block 4 is slidably installed in the mounting base 2, which avoids the mounting block 4 from shaking or shifting in the mounting groove 3. The mounting block 4 can be fixed in the mounting base 2 by using bolts, which enhances stability.

[0031] Specifically, the inner wall shape and size of the T-slot 602 match the outer wall shape and size of the T-block 604, and the inner wall of the T-slot 602 fits into the outer wall of the T-block 604.

[0032] The above technical solution enables the T-block 604 to slide into the T-groove 602 during installation, and the two fit tightly together. This not only facilitates the quick splicing of the fixing blocks 601, but also ensures the stability of the connection between the fixing blocks 601 after splicing. After the T-block 604 slides into the T-groove 602, the first threaded hole 603 and the second threaded hole 605 can be quickly aligned.

[0033] Specifically, the fixing block 601 is fixed to the T-block 604 by fastening bolt 606, and one end of the fastening bolt 606 is threaded through the first threaded hole 603 and extends into the second threaded hole 605 for connection.

[0034] Through the above technical solution, the fastening bolt 606 can firmly fix the T-block 604 in the T-slot 602, strengthen the connection strength between it and the fixing block 601, prevent the fixing block 601 from loosening or falling off during the operation of the labeling machine, ensure the structural stability after the number of suction heads is adjusted, and ensure the normal operation of the equipment.

[0035] Specifically, there are four circular grooves 701, and two circular grooves 701 form a group, with the two groups of circular grooves 701 symmetrically opened on the fixed block 601.

[0036] Through the above technical solution, the four circular grooves 701 correspond to the four sliding rods 702 respectively. When the four sliding rods 702 slide, they ensure the stability of the suction head seat 705 during the movement process and prevent the suction head seat 705 from tilting, thereby ensuring that the suction head body 710 can accurately adsorb and stick the label.

[0037] Specifically, one end of the sliding rod 702 passes through the spring 704 and the circular groove 701 and is connected to the suction head seat 705, and the outer wall of the sliding rod 702 is in contact with the inner wall of the circular groove 701.

[0038] The above technical solution makes the sliding rod 702 slide more smoothly in the circular groove 701, avoids jamming, ensures the flexible movement of the suction head seat 705, and the circular groove 701 can guide the sliding rod 702 to ensure the stable movement of the sliding rod 702.

[0039] Specifically, the suction head seat 705 forms a threaded structure with the threaded head 709 through the threaded groove 707, and one end of the threaded head 709 extends into the threaded groove 707 for connection.

[0040] Through the above technical solution, the threaded connection method makes the connection and disassembly of the suction head body 710 and the suction head base 705 more convenient and quick. Installation or replacement can be completed simply by rotating the suction head body 710. At the same time, the threaded connection has good sealing and firmness, which can ensure that the suction head body 710 will not easily fall off during operation, ensuring the normal operation of the adsorption work.

[0041] In use, first slide the mounting block 4 into the mounting groove 3 of the mounting base 2, and then fix the mounting block 4 in the mounting base 2 with bolts to complete the basic installation. The number of suction heads can be flexibly adjusted according to the number of labels required for production. When it is necessary to increase the number of suction heads, use the cooperation between the T-slot 602 and the T-block 604 to slide the T-block 604 on the new fixing block 601 into the T-slot 602 of the existing fixing block 601. At this time, the T-slot 602 and the T-block 604 fit tightly, ensuring the stability of the connection between the fixing blocks 601 after splicing, and enabling rapid assembly. Align the first threaded hole 603 and the second threaded hole 605, and then fix them by passing the fastening bolt 606 through the first threaded hole 603 and the second threaded hole 605, thus increasing the number of suction heads. Conversely, when it is necessary to reduce the number of suction heads, simply unscrew the corresponding fastening bolt 606 and slide out the corresponding fixing block 601. In this way, the number of suction heads can be flexibly adjusted according to the number of labels, meeting diverse production needs and improving the versatility of the equipment. When the suction head body 710 is worn, damaged, or needs to be replaced with a different type of suction head to adapt to different labels, the suction head can be adjusted accordingly. To disassemble the suction head body 710, simply rotate the suction head body 710 and remove the threaded head 709 from the threaded groove 707. For installation, screw the threaded head 709 onto the suction head body 710 into the threaded groove 707. The threaded head 709 presses against the sealing gasket 708, enhancing the seal. The operation is simple and quick, requiring no complicated tools or steps, shortening replacement time and improving production efficiency. When adsorbing labels, connect the air inlet pipe 706 to the air source. The through hole 711 on the suction head body 710 generates adsorption force. When the suction head body 710 moves down to contact the label... The sliding rod 702 slides within the circular groove 701. The fixed block 601 presses down on the spring 704, causing it to deform and contract. The elasticity of the spring 704 provides a certain buffer for the suction head body 710, preventing rigid collisions between the suction head body 710 and the label. This protects both the suction head body 710 and the label, while ensuring close contact between them and guaranteeing stable adsorption. The suction head body 710 then adsorbs the label, thus completing the entire process. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
