DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Embodiment: please refer to Figures 1 to 4 A pad printing machine convenient for replacing glue head, comprising a pad printing machine body 1, the pad printing machine body 1 is connected with mounting seat 2 through lifting mechanism, the bottom of mounting seat 2 is detachably connected with glue head body 3, the lifting mechanism generally adopts air cylinder, the mounting seat 2 is driven to move downward by air cylinder, that is, the pattern is transferred on the printed matter by glue head body 3, this is prior art, and will not be repeated here.

[0029] The embodiment also includes fixed plate 4, first mounting sleeve 5, second mounting sleeve 6, mounting column 8, four mounting grooves 9, four limiting pieces 10 and two pressing rods 12.

[0030] The fixing plate 4 is fixed to the bottom of the mounting base 2 and used for connecting with other components. The first mounting sleeve 5 is fixed to the middle of the fixing plate 4. The second mounting sleeve 6 is located below the first mounting sleeve 5 and the lower end surface is attached to the glue head body 3. A plurality of fixing rods 7 are fixedly connected between the second mounting sleeve 6 and the fixing plate 4, used for fixedly connecting the second mounting sleeve 6 and the fixing plate 4. In this embodiment, the first mounting sleeve 5 and the second mounting sleeve 6 have the same structure and coaxial, facilitating the installation column 8 to be inserted into the first mounting sleeve 5 and the second mounting sleeve 6.

[0031] The installation column 8 is fixed to the upper end of the glue head body 3 and moves through the second mounting sleeve 6 and the first mounting sleeve 5 in the vertical direction. When it is necessary to replace the glue head body 3, the installation column 8 is pulled out of the second mounting sleeve 6 and the first mounting sleeve 5, and the glue head body 3 can be removed.

[0032] It should be noted that the four installation grooves 9 are evenly distributed on the bottom of the first mounting sleeve 5 and the top of the second mounting sleeve 6. The two installation grooves 9 on the bottom of the first mounting sleeve 5 and the two installation grooves 9 on the top of the second mounting sleeve 6 are symmetrically arranged along the axis of the installation column 8, so as to facilitate the two pressing rods 12 to move close to or away from each other.

[0033] Preferably, the bottom of the second mounting sleeve 6 is fixedly provided with two positioning columns 14 symmetrically arranged left and right. The top of the glue head body 3 is provided with positioning holes 15 corresponding to the positioning columns 14 one by one. Each positioning column 14 is movably inserted into the corresponding positioning hole 15 in the vertical direction. When installing the glue head body 3, the positioning column 14 is inserted into the positioning hole 15, so that the position of the installation column 8 can be positioned. After the installation column 8 is inserted into the second mounting sleeve 6 and the first mounting sleeve 5, the limiting part 10 can be aligned with the limiting hole 11 to avoid deviation.

[0034] The limiting part 10 is described as follows:

[0035] The four limiting parts 10 are movably arranged in the corresponding installation grooves 9. The installation column 8 is provided with limiting holes 11 corresponding to the limiting parts 10 one by one. Each limiting part 10 is movably inserted into the corresponding limiting hole 11 in the horizontal direction, so that the installation column 8 cannot rotate or move axially, thereby being able to be fixedly installed with the glue head body 3. Moreover, this kind of multi-point fixing method can more stably fix the glue head body 3. In the use process, the glue head body 3 is not easy to fall off or shake.

[0036] Specifically, the limiting part 10 includes a movable plate 1001 movably arranged in the installation groove 9 in the vertical direction. A plurality of limiting columns 1002 are fixedly arranged on the movable plate 1001 in parallel and at intervals. Each limiting column 1002 is movably inserted into the corresponding limiting hole 11 in the horizontal direction, thereby fixing the installation column 8.

[0037] Further, the mounting slot 9 is fixed with a sliding rod 18 movably penetrating the movable plate 1001 in the horizontal direction, and a second spring 19 is sleeved on the sliding rod 18, which always applies an outward elastic force to the movable plate 1001 to ensure that the limiting column 1002 can normally penetrate into the corresponding limiting hole 11, thereby ensuring the stability of the installation of the mounting column 8.

[0038] The linkage mechanism 13 is described as follows:

[0039] The two pressing rods 12 are located on the two sides of the mounting column 8, and the upper and lower ends of each pressing rod 12 movably extend into the corresponding mounting slot 9, and a linkage mechanism 13 is connected between each pressing rod 12 and the corresponding limiting piece 10; when the two pressing rods 12 are close to each other, the limiting piece 10 is driven by the linkage mechanism 13 to disengage from the limiting hole 11.

[0040] In this embodiment, the mounting slot 9 is fixed with a guide rod 16 movably penetrating the pressing rod 12 in the horizontal direction, and a first spring 17 is sleeved on the guide rod 16, which always applies an outward elastic force to the pressing rod 12, so that in the normal state, the pressing rod 12 can be away from the mounting column 8 under the action of the elastic force of the first spring 17.

[0041] Specifically, the linkage mechanism 13 includes a linkage wheel 1301 rotating in the mounting slot 9 through a rotating shaft, and a first linkage rod 1302 and a second linkage rod 1303 are respectively hinged at the upper and lower ends of the linkage wheel 1301; one end of the first linkage rod 1302 away from the linkage wheel 1301 is hinged with the limiting piece 10, and one end of the second linkage rod 1303 away from the linkage wheel 1301 is hinged with the pressing rod 12. When the linkage wheel 1301 rotates, the limiting piece 10 and the pressing rod 12 can be brought close to or away from each other through the cooperation of the first linkage rod 1302 and the second linkage rod 1303.

[0042] The working principle is as follows:

[0043] When it is necessary to replace the rubber head body 3, the operator holds the two pressing rods 12 with one hand and holds the rubber head body 3 with the other hand, and then makes the two pressing rods 12 close to each other, which can drive the linkage wheel 1301 to rotate through the second linkage rod 1303, thereby driving the movable plate 1001 to move towards the linkage wheel 1301 through the first linkage rod 1302, so that the limiting column 1002 can disengage from the limiting hole 11, and then the mounting column 8 can be pulled out from the second mounting sleeve 6 and the first mounting sleeve 5, so that the rubber head body 3 can be removed.

[0044] The operator holds the new rubber head body 3, inserts the mounting column 8 on the new rubber head body 3 into the second mounting sleeve 6 and the first mounting sleeve 5, and in the process, the positioning column 14 needs to be inserted into the positioning hole 15 to position the mounting column 8 and avoid misalignment of the limiting column 1002 and the limiting hole 11. When the mounting column 8 is inserted to the limiting position, the operator releases the two pressing rods 12, so that the linkage wheel 1301 is rotated under the action of the first spring 17 and the second spring 19, the pressing rod 12 and the movable plate 1001 are reset, and then the limiting column 1002 is inserted into the corresponding limiting hole 11, that is, the installation of the rubber head body 3 is completed, and the operation is relatively convenient without the aid of tools.

[0045] Therefore, the limiting member can be driven by the linkage mechanism to be separated from the limiting hole; at the same time, the other hand of the operator holds the rubber head body, and the mounting column is pulled out from the first mounting sleeve and the second mounting sleeve, so that the rubber head body can be disassembled without the aid of a wrench or other tools, and the disassembly and installation of the rubber head body are more convenient and fast.

[0046] It should be noted that in this text, relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment. Without more limitations, the element defined by the statement "including a" does not exclude the presence of another identical element in the process, method, article or equipment including the element.

[0047] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
