DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0026] Embodiment one

[0027] As shown in Figures 1-3 , 7, the embodiment discloses a portable edge band puncher, which comprises a mounting seat 1 and a die holder 2 arranged above the mounting seat 1. The die holder 2 is detachably arranged above the mounting seat 1, a punching hole 21 corresponding to the position of a punch 5 is arranged through the die holder 2, a material channel 22 for the edge band to pass through is arranged on one side of the die holder 2, and the material channel 22 is in communication with the middle part of the punching hole 21. The die holder 2 is fixed to the mounting seat 1 by bolts, and users can replace the die holder 2 with different sizes of punching holes 21 to punch different sizes of perfect pastes.

[0028] An installation cavity 3 is arranged in the mounting seat 1, a driving block 4 connected to the punch 5 is arranged in the installation cavity 3 and can slide up and down; the punch 5 is threadedly connected to the driving block 4, and users can disassemble the punch 5 so that the punch 5 can be replaced and adjusted according to the size of the die holder 2.

[0029] As shown in Figure 2As shown, the mechanical structure for driving the driving block 4 to reciprocate up and down includes a rotating member 6 rotatably arranged on the mounting base 1, and the rotating member 6 is in transmission connection with the driving block 4 through a transmission assembly 7 to realize the up-and-down sliding of the driving block 4. The rotating member 6 is a columnar member rotatably arranged on one side of the mounting base 1 through a bearing, and in this application, a screw hole 61 is arranged on the end surface exposed to the outside, which is a hexagonal screw hole 61 or a quadrangular screw hole 61. This screw hole 61 is matched with the drill bit of an electric drill, so that the user can drive the rotating member 6 to rotate through the electric drill which will be used to cut during the work, thereby realizing the perfect patch production. The external power source includes but is not limited to the electric drill, and some commonly used tools such as hexagonal wrenches can also be used to manually drive the rotating member 6 to work. These tools are commonly used in furniture installation and production sites, so there is no need to carry additional power sources or air pumps and other electrical elements, thereby reducing the burden on the workers and reducing the size of the equipment, making it more convenient to carry. Moreover, the electric drill can drive the punch 5 to work, which can realize the continuous work of the punch 5 compared with the air pump and the air cylinder, thereby improving the efficiency of the perfect patch production.

[0030] As shown in Figure 3 The transmission assembly 7 can adopt a cam structure but is not limited to the cam structure. Specifically, the cam structure includes an eccentric cam 71 eccentrically arranged on the side of the rotating member 6 opposite to the driving block 4 and protrudingly arranged. The driving block 4 is provided with a sliding groove 72 in abutting and sliding cooperation with the circumferential side of the eccentric cam 71. The sliding groove 72 is provided with a lower driving surface and an upper driving surface. The lower driving surface is located on the side of the driving block 4 away from the mold base 2, and is used to cooperate with the eccentric cam 71 to drive the driving block 4 to approach the mold base 2. The upper driving surface is arranged opposite to the lower driving surface.

[0031] When the tool is actually working, when using the portable edge strip punch, the user first places the edge strip in the material channel 22 of the mold base 2, adjusts the position of the edge strip according to the position of the circular gasket (perfect patch) to be punched out, and then selects a suitable power source to drive the rotating member 6 to rotate, for example, connects the screw hole 61 on the rotating member 6 with the electric drill, and after starting the electric drill, the rotating member 6 starts to rotate. Then the rotating member 6 rotates to drive the eccentric cam 71 to rotate. The eccentric cam 71 first pushes the driving block 4 to move towards the mold base 2 through the lower driving surface, so that the punch 5 approaches and punches the edge strip. Then the eccentric cam 71 continues to rotate and contacts with the upper driving surface. The driving block 4 moves away from the mold base 2 under the driving of the upper driving surface, thereby completing a reciprocating punching action. In this way, a plurality of circular gaskets can be continuously punched out, and finally the perfect patch production is completed.

[0032] The cam structure does not need a large movement space, thereby not increasing the size of the equipment.

[0033] Through the above structure, a mechanical transmission structure is adopted, without external devices such as air pumps and power supplies, only necessary mechanical components are reserved to realize the driving of the punching knife 5, compared with the traditional scheme, the space occupation is greatly reduced, the overall volume is significantly reduced, and it is convenient for carpenters to carry and operate at various furniture installation sites.

[0034] On the basis of the above, the existing edge strip puncher can only realize simple perfect paste production, the function is single, the practicability is low, therefore, as Figures 1-2 Indicated, the round wood turning mechanism 8 is detachably arranged on the mounting seat 1, and the round wood turning mechanism 8 can turn the wood stick rotating under the action of external force to process the wood stick into a cylindrical structure.

[0035] Because in the furniture manufacturing and installation process, not only the perfect paste needs to cover the screw hole, but also the wood sticks of different sizes need to be processed for use as connecting pieces to realize the connection of furniture parts; by integrating the round wood turning mechanism 8 on the portable edge strip puncher, if the wood turning processing of the round wood is needed after the operation of punching out the perfect paste by the edge strip puncher, a separate turning tool does not need to be found and prepared. The time for preparing the tool and adjusting the working state is saved. For example, when assembling a furniture, the carpenter may first use the puncher to punch out the perfect paste for the edge strip, and then need to turn a wood stick used to make a furniture handle. He can quickly switch the operation without leaving the working position, realizing efficient continuous operation.

[0036] At the same time, for the furniture manufacturing site with limited working space, the integrated tool has more advantages. If the round wood turning mechanism 8 is a separate tool, it needs to occupy additional space and needs a special storage place when in use. By integrating it on the puncher, no additional space is needed for storage, and it forms a whole with the puncher, which is convenient for carrying and management. When the working position needs to be moved, only the integrated tool needs to be moved, reducing the difficulty of tool management and the occupied space.

[0037] Moreover, this integrated design makes a tool have two functions, enhances its applicability in different stages, and can reduce the procurement cost of the tool to a certain extent and improve the comprehensive utilization rate of the tool.

[0038] Among them, as Figures 1-2As shown, the log turning mechanism 8 includes a fixed block 81 provided on the mounting base 1, the fixed block 81 is provided with a positioning through hole 82, the inlet end of the positioning through hole 82 is provided with a cutting edge 83; One side of the mounting base 1 is provided with a clamping groove 84, the fixed block 81 is located in the clamping groove 84 and is fixedly connected with the mounting block through bolts; The fixed block 81 can be fixed in the clamping groove 84 by bolts, so as to fix the position of the fixed block 81, and through bolt mounting, the fixed block 81 can be conveniently disassembled, so that different sizes of fixed blocks 81 with different sizes of positioning through holes 82 can be replaced to process different sizes of log rods.

[0039] As shown in Figure 6 Whether it is a punch or a log turning mechanism 8, its position needs to be fixed during use, so as to avoid the influence of position deviation on material processing during use. Among them, the existing punch is fixed on the table through screws. This way not only causes disassembly and transportation trouble, but also damages the table top.

[0040] Therefore, a clamping seat 9 is arranged at the bottom of the mounting base 1, the clamping seat 9 includes a one-word sliding rail 91 which is in sliding fit with the bottom of the mounting base 1 and a bottom plate 92 corresponding to the mounting base 1, the bottom plate 92 is provided with a threaded hole, a bolt is threadedly connected in the threaded hole, and a locking piece 93 parallel to the bottom surface of the mounting base 1 is arranged at the end of the bolt; It also includes a pair of vertically distributed connecting grooves 94 arranged at the bottom of the mounting base 1, and the sliding rail 91 is in sliding fit with the two connecting grooves 94 respectively.

[0041] The two connecting grooves 94 are arranged in a cross shape and are in sliding connection with the one-word sliding rail 91, so that the user can change the installation direction of the punch and the log turning mechanism 8 by changing the position of the sliding rail 91, thereby making the user use more convenient and handy.
