Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0037] As attached Figure 1 ~Appendix Figure 3 As shown, this embodiment provides an auxiliary fixing device for hot stamping on bamboo products, which is installed on a hot stamping machine 1; the hot stamping machine 1 includes at least a cylinder 11, a lifting plate 12 connected to the cylinder 11, and a hot stamping plate 13 installed on the end of the lifting plate 12 away from the cylinder 11; the lifting plate 12 moves along a first direction D1 or the opposite direction of the first direction D1; the installation direction of the hot stamping plate 13 is parallel to the second direction D2.
[0038] It is understood that the hot stamping machine mentioned in this embodiment is prior art, generally including a frame module, a heating and pressurizing module, etc. The frame module mainly includes a base for placing the hot stamping plate, and the upper surface of the base is provided with a high-temperature resistant ceramic panel. The heating and pressurizing module mainly includes a cylinder 11, a lifting plate 12, and a hot stamping plate 13. A precision pressure regulating valve can be installed at the cylinder 11. The lifting plate 12 is mainly used to install the hot stamping plate 13, and a buffer layer or buffer spring can be provided between the two. The hot stamping plate 13 is equipped with common components such as a heating plate and a temperature sensor. The first direction D1 refers to the downward direction of the hot stamping plate 13, and the second direction D2 is perpendicular to the first direction D1 and parallel to the surface of the base.
[0039] The auxiliary fixture provided in this embodiment mainly serves to position and fix the board to be hot-stamped. Its specific structure is as follows:
[0040] The auxiliary fixing device includes a fixing structure 2 connected to the lifting plate 12, and a pressure plate structure 3 slidably connected to the fixing structure 2 and moving along a first direction D1 or the opposite direction of the first direction D1. The fixing structure 2 has at least one sliding groove 21 and a support spring 22 installed in the sliding groove 21; the pressure plate structure 3 includes at least a moving rod 31 slidably connected to the sliding groove 21; the end of the moving rod 31 located in the sliding groove 21 is connected to the support spring 22, and the end of the moving rod 31 located outside the sliding groove 21 is connected to a pressure plate body 32 arranged along a second direction D2.
[0041] The movable rod 31 can move within the sliding groove 21 along the first direction D1 or in the opposite direction of the first direction D1. The support spring 22 provides support force to the movable rod 31 along the first direction D1. When the pressure plate body 32 is not subjected to a force in the opposite direction D1, the support spring 22 is in a stretched state. At this time, the depth of the movable rod 31 in the sliding groove 21 is the smallest, and the height of the pressure plate body 32 is less than the height of the hot stamping plate 13. When the cylinder 11 drives the hot stamping plate 13 to descend along the first direction D1, the pressure plate body 32 contacts the hot stamping plate body before the hot stamping plate 13, and the force between the two gradually increases as it descends. At this time, the support spring 22 is compressed, and the movable rod 31 retracts into the sliding groove 21. When the support spring 22 is compressed to near its limit, the pressure plate body 32 exerts the greatest force on the hot stamping plate body. Therefore, the support spring 22 is one of the key components to ensure a good fixing effect. Ideally, the support spring 22 should be close to its compression limit when the hot stamping plate 13 is in pressure contact with the plate to be stamped. At this point, the hot stamping effect is best, and the fixing effect of the pressure plate body 32 is also optimal. Understandably, to reduce damage to the plate to be stamped, a buffer layer can be provided on the lower surface of the pressure plate body 32. The buffer layer can be made of commonly used materials, such as a rubber layer with a thickness of approximately 0.5~1.0 mm.
[0042] It is worth noting that the number of fixing structures 2 and pressure plate structures 3 corresponds one-to-one. In order not to interfere with the operation of the hot stamping plate 13, the pressure plate structure 3 is mainly used to fix the corners of the hot stamping plate. Therefore, the number of pressure plate structures 3 should be two in a group, and the two in a group are used to fix the two symmetrically arranged corners of the hot stamping plate. Therefore, the total number of auxiliary fixing devices is at least two, and they are symmetrically arranged on both sides of the lifting plate 12.
[0043] In this embodiment, the fixing structure 2 includes a fixing cylinder 23 and a fixing cover 24; the sliding groove 21 is disposed through the fixing cylinder 23; the middle part of the fixing cover 24 is connected to the end of the support spring 22, and an annular extension 241 distributed along the first direction D1 is provided on the periphery of the fixing cover 24; an internal thread is provided on the inner wall of the annular extension 241, and an external thread matching the internal thread is provided on the outer periphery of the end of the fixing cylinder 23 away from the pressure plate body 32.
[0044] The fixing cover 24 is designed primarily to facilitate the removal of the support spring 22. As mentioned above, the support spring 22 directly affects the fixing effect and the hot stamping effect. Therefore, different specifications of support spring 22 need to be selected for different hot stamping objects. Furthermore, the support spring 22 needs to be replaced promptly after repeated use when it becomes fatigued or worn out. The support spring 22 can be easily removed individually by unscrewing the fixing cover 24.
[0045] In this embodiment, the fixed cylinder 23 has a slot 25 on its end near the pressure plate body 32, which communicates with the sliding groove 21. The pressure plate body 32 retracts into the slot 25. "The pressure plate body 32 retracts into the slot 25" refers to a special state in which the support spring 32 is close to its maximum compression state, the moving rod 31 is inserted to the maximum depth into the sliding groove 21, and part or all of the pressure plate body 32 can retract into the slot 25. The slot 25 has a certain limiting effect on the position of the pressure plate body 32, thereby improving the stability of the pressure plate body 32 before entering this state.
[0046] As some preferred embodiments, the auxiliary fixation device further includes a correction structure 4; the correction structure 4 includes a fixing plate 41 disposed on the surface of the pressure plate body 32 near the fixing structure 2, an adjusting plate 42 slidably connected to the fixing plate 41 along a second direction D2 or the opposite direction of the second direction D2, and a lever plate 43 disposed at the end of the adjusting plate 42 away from the fixing plate 41 and distributed along a first direction D1; the height of the lever plate 43 is greater than the thickness of the pressure plate body 32.
[0047] The sliding connection between the fixed plate 41 and the adjusting plate 42 allows the position of the dial plate 43 to move along the second direction D2 or in the opposite direction of the second direction D2. The relative position between the fixed plate 41 and the adjusting plate 42 can be locked, thus fixing the position of the dial plate 43. The position of the dial plate 43 is determined by the edge position of the lettering plate, that is, the angle formed between the dial plate 43 and the adjusting plate 42 engages with the edge corner of the lettering plate, thereby further defining the fixed position of the lettering plate and strengthening the fixing effect. Preferably, the adjusting plate 42 is provided with scale lines 49 to facilitate position adjustment. Before the pressure plate body 32 contacts the lettering plate, the dial plate 47 first contacts the side of the lettering plate; the two opposing dial plates 47 define the positions of the two sides of the lettering plate, which helps to improve the accuracy of the lettering position. It is worth noting that the pawl 47 has a corrective effect on the position of a lettering plate that is slightly tilted. Furthermore, the two opposing pawls 47 can extend at different heights along the first direction D1, so that the two sides of the lettering plate come into contact with the two pawls 47 at different times. This time difference helps to correct the tilt of the lettering plate. Moreover, a slope 47 is formed on the end of the pawl 43 near the pressure plate body 32. The slope 47 reduces the pressure wear between the pawl 43 and the side of the lettering plate.
[0048] Specifically, one example of the locking structure between the fixed plate 41 and the adjusting plate 42 is as follows: the fixed plate 41 is provided with an adjusting groove 44 that is slidably connected to the adjusting plate 42, and the adjusting plate 42 is provided with a plurality of threaded holes 45 spaced apart along the second direction. A fastening bolt 46 is screwed into the threaded hole 45, which penetrates the adjusting plate 42 and whose end abuts against the bottom surface of the adjusting groove 44.
[0049] As some preferred embodiments, a specific structure is proposed for the correction structure 4 to be installed on the pressure plate structure 3: the end of the fixing plate 41 away from the lever plate 43 is formed with an opening groove 411 that faces the moving rod 31 and is engaged with the moving rod 31, and at least two oppositely arranged fixing screw holes 412 are provided on the groove wall of the opening groove 411; a fixing bolt 48 is provided and installed in the two fixing screw holes 412, and the side of the fixing bolt 48 abuts against the side of the moving rod 31.
[0050] The opening slot 412 is a C-shaped slot, and the bottom arc-shaped part of the slot matches the shape of the moving rod 31 to improve the fixing effect. The fixing bolt 48 is used to abut against the other side of the moving rod 31 to ensure the tight connection between the fixing plate 41 and the moving rod 31.
[0051] In some preferred embodiments, a connecting plate 5 is provided between the two symmetrically distributed auxiliary fixators; the two ends of the connecting plate 5 are respectively connected to the two correction structures 4; and the end of the connecting plate 5 has an insert plate 51 that is inserted into the opening slot 411, and the insert plate 51 is provided with mounting screw holes 52 that match the fixing screw holes 412.
[0052] The fixing screw holes 412 are arranged in pairs, with at least one additional pair for matching the mounting screw holes 52 on the insert plate 51. The insert plate 51 can directly replace the fixing bolt 48 and abut against the moving rod 31, or it can abut against the side of the fixing bolt 48 away from the moving rod 31. In this case, at least one additional fixing bolt 48 is required to fix the insert plate 51. The main function of the insert plate 51 is to connect two oppositely arranged auxiliary fixing devices. Since the auxiliary fixing devices are located directly above the corner of the lettering plate, the added insert plate 51 will not interfere with the operation of the lettering plate 13. The main function of the insert plate 51 is to enhance the synchronization of the two auxiliary fixing devices, thereby improving the fixing effect on the lettering plate.
[0053] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
