[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution: a pad printer with a replaceable pad head, comprising a pad printer housing 1, the upper surface of the pad printer housing 1 being provided with a lifting structure and a positioning structure, a lifting seat 5 being installed on the lifting structure, a detachable pad head body 8 being provided below the lifting seat 5, a mounting groove 51 for mounting the pad head body 8 being provided on the lower surface of the lifting seat 5, a locking assembly 6 for positioning the pad head body 8 being provided in the mounting groove 51, a side groove 55 being provided on one side of the lifting seat 5, an unlocking assembly 7 being slidably provided in the side groove 55 and being slidably provided with two sets of locking assemblies 6;

[0024] The locking assembly 6 includes a card plate 61, with a card block 62 fixedly connected to both ends of one side of the card plate 61, a telescopic rod 66 fixedly connected to the other side of the card plate 61, a first spring 67 is sleeved on the outer side of the telescopic rod 66, and a right-angle block 64 is fixedly connected to the side of the card plate 61 adjacent to the telescopic rod 66;

[0025] The unlocking component 7 includes a resisting block 71. Both corners on one side of the resisting block 71 are inclined. One ends of two groups of right-angle blocks 64 are provided with inclined portions 65 that抵触 the resisting block 71.

[0026] The upper end of the rubber head body 8 is provided with a connecting column 81 inserted into the installation groove 51. Two groups of card slots 82 for inserting the card slots 82 are opened on the outer side of the connecting column 81. The card slots 82 are arranged in a circular shape. By using the card slots 82 on the connecting column 81, it is convenient to install the rubber head body 8 at different angles, thereby reducing the installation difficulty and improving the disassembly and assembly efficiency.

[0027] Both sides of the inner cavity of the installation groove 51 are provided with sliding grooves 52 for the sliding setting of the clamping plates 61. The bottom of the sliding groove 52 is provided with a bottom groove 53 for installing the telescopic rod 66. One side of the inner cavity of the sliding groove 52 is provided with a guiding groove 54 for the sliding setting of the right-angle block 64. The guiding groove 54 is arranged in a U shape. By means of the right-angle block 64, the stability of driving the clamping plate 61 to move is improved, so as to facilitate the synchronous movement of the clamping plate 61, so as to disassemble and assemble the rubber head body 8, and the stability of the rubber head body 8 during disassembly and assembly is improved.

[0028] Both sides of the clamping plate 61 adjacent to the telescopic rod 66 are fixedly connected with first limiting blocks 63. Both sides of the inner cavity of the sliding groove 52 are provided with first grooves (not shown in the figure) for the sliding setting of the first limiting blocks 63. By sliding the first limiting blocks 63 in the grooves, the stability of the movement of the clamping plate 61 is improved, so as to ensure the stability of the engagement between the clamping block 62 and the card slot 82.

[0029] The other side of the resisting block 71 is fixedly connected with a button 74. One end of the resisting block 71 adjacent to the button 74 is cylindrical. The outer side of the resisting block 71 is sleeved with a second spring 73 that抵触 the button 74. The upper surface of the resisting block 71 is fixedly connected with a second limiting block 72. The top of the inner cavity of the side groove 55 is provided with a second groove (not shown in the figure) for the sliding setting of the second limiting block 72. The second spring 73 can quickly drive the button 74 to reset, so as to facilitate the next disassembly of the rubber head body 8. Secondly, the second limiting block 72 can prevent the resisting block 71 from falling off.

[0030] The lifting structure includes a guiding frame 2, a motor 3 and a screw rod 4. The screw rod 4 is rotatably arranged in the inner cavity of the guiding frame 2. The upper end of the screw rod 4 penetrates through the guiding frame 2 and is driven by the motor 3. The lifting seat 5 is provided with a limiting groove 56 that slides with the guiding frame 2. The lower end of the screw rod 4 is threadedly connected with the lifting seat 5. By driving the screw rod 4 by the motor 3, it is convenient to adjust the height of the lifting seat 5, so as to facilitate the rubber head body 8 to print the product and improve the printing efficiency.

[0031] The positioning structure includes two groups of fixed plates 9 fixedly connected to the upper surface of the pad printing machine housing 1. Cylinders 10 are provided on opposite sides of the two groups of fixed plates 9. The telescopic ends of the cylinders 10 pass through the fixed plates 9 and are fixedly connected to clamps 11. One side of the clamps 11 is fixedly connected to a guide rod 12 passing through the fixed plates 9. The guide rod 12 improves the stability of the movement of the clamps 11, thereby improving the stability of the products to be printed and improving the printing quality.

[0032] When the damaged rubber head body 8 is disassembled, the staff applies pressure on the button 74, compressing the second spring 73 while causing the resisting block 71 to conflict with the inclined portion 65 of the right-angled block 64, so that the right-angled block 64 drives the card plate 61 to move along the slide groove 52. At the same time, the right-angled block 64 slides in the guide groove 54 and the first limit block 63 slides in the first groove, thereby improving the sliding stability of the card plate 61 in the slide groove 52. The card plate 61 compresses the first spring 67 on the telescopic rod 66, and the block 62 on the card plate 61 disengages from the slot 82 of the connecting column 81, thereby facilitating the connection column 81 to be drawn out of the mounting slot 51, thereby improving the disassembly efficiency of the rubber head pump body. The pressure on the button 74 is released, and the card plate 61 and the resisting block 71 are reset under the elastic potential energy of the first spring 67 and the second spring 73.

[0033] When installing a new rubber head body 8, align the connecting column 81 with the installation groove 51 and apply upward thrust. The top edge of the connecting column 81 and the lower edge of the upper slot 82 are both rounded, and the lower corner of the block 62 is rounded, so as to reduce the resistance of the connecting column 81 to the installation groove 51, and the first spring 67 is compressed during the friction process. When the slot 82 of the connecting column 81 and the block 62 fit into the same plane, under the action of the elastic potential energy of the first spring 67, the block 62 on the card plate 61 is pushed and embedded in the slot 82, thereby completing the fixation of the connecting column 81, and the rubber head body 8 can be quickly installed, thereby improving the installation efficiency.

[0034] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
