Description
Technical field:
The utility model relates to fuse machine technical field, refers in particular to fuse machine hot melt head.
Background technology:
Need to use fuse machine by pre-for pcb board riveted in pcb board manufacture process, see shown in Fig. 1,2, the heat fusion joint of the hot melt head 1 ' that current fuse machine uses is 2 heated types, namely at rear end projection two heat fusion joints 2 ' of hot melt head, hot melt area is little, and Btu utilization is insufficient, and heating effect is bad, and the sunk part in the middle of two heat fusion joints 2 ' is when clearing up, the resin be stained with in more difficult cleaning reflow process; The second half section of hot melt head 1 ' is flat structure in addition, makes the position overall volume near two heat fusion joints 2 ' less, is unfavorable for that heat stores.
Utility model content:
The purpose of this utility model is exactly the deficiency that exists for prior art and provides a kind of and can increase the clean fuse machine hot melt head of good, the convenient maintenance of hot melt area, heating effect.
To achieve these goals, the technical solution adopted in the utility model is: fuse machine hot melt head, it includes cylindrical hot melt head body, the front end of hot melt head body has protruded out cylindrical projection, be convexly equipped with strip hot melt bar in the middle part of the rear end face of hot melt head body, the two ends of hot melt bar extend to the circumferential exterior surface place of hot melt head body respectively.
The width of described hot melt bar and the ratio of this body diameter of hot melt head are 1/4 ~ 1/3.
The front end face of described hot melt bar is planar structure.
The external diameter of described projection is less than the external diameter of hot melt head body.
Described projection front end edge axle center offers endoporus, and endoporus extends to hot melt head body interior near the position of rear end, and hot melt head body circumferential exterior surface offers the position, hole be communicated with endoporus.
The utility model beneficial effect is: the fuse machine hot melt head that the utility model provides, it includes cylindrical hot melt head body, the front end of hot melt head body has protruded out cylindrical projection, strip hot melt bar is convexly equipped with in the middle part of the rear end face of hot melt head body, the two ends of hot melt bar extend to the circumferential exterior surface place of hot melt head body respectively, the utility model utilizes hot melt bar as heat fusion joint, increase hot melt area, improve heat utilization ratio, heating effect is good, and strip hot melt bar eliminates the recess space between conventional hot melt two heat fusion joints, can not cull, the maintenance after hot melt is facilitated to clean, hot melt head body is cylindrical structural in addition, increases the volume of heat storage structure, is beneficial to store heat energy, shortens the distance of heat trnasfer, to conduct heat rapidly simultaneously.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of existing hot melt head.
Fig. 2 is the rearview of existing hot melt head.
Fig. 3 is the cut-away view of the utility model hot melt head.
Fig. 4 is the rearview of the utility model hot melt head.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described, see shown in Fig. 3 ~ 4, the utility model includes cylindrical hot melt head body 1, the front end of hot melt head body 1 has protruded out cylindrical projection 2, be convexly equipped with strip hot melt bar 3 in the middle part of the rear end face of hot melt head body 1, the two ends of hot melt bar 3 extend to the circumferential exterior surface place of hot melt head body 1 respectively.
The width of hot melt bar 3 and the ratio of hot melt head body 1 external diameter are 1/4 ~ 1/3, and hot melt area is large.The front end face of hot melt bar 3 is planar structure, and hot melt is effective.The external diameter of projection 2 is less than the external diameter of hot melt head body 1.Projection 2 front end edge axle center offers endoporus 4, and endoporus 4 extends to the inner position near rear end of hot melt head body 1, and hot melt head body 1 circumferential exterior surface offers the position, hole 5 be communicated with endoporus 4, and endoporus 4 can place heater.
The utility model utilizes hot melt bar 3 as heat fusion joint, increases hot melt area, improves heat utilization ratio, heating effect is good, and strip hot melt bar 3 eliminates the recess space between conventional hot melt two heat fusion joints, can not cull, facilitate the maintenance after hot melt to clean; Hot melt head body 1 is cylindrical structural in addition, increases the volume of heat storage structure, is beneficial to store heat energy, shortens the distance of heat trnasfer simultaneously, to conduct heat rapidly, and increases the front end of internal cavities, to put more powerful heater.The utility model hot melt head uses low-voltage, high current heater, during the cooling of hot melt head, and the heat of heater energy heat make-up loss at once.
Certainly, the above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
