Description

Knife bar heater with adjustable heating hood barrier structure

The present invention relates to a device for installing or removing a cutter, in particular to a knife bar heating machine with an adjustable heating hood barrier structure capable of adjusting and stably heating the heating hood provided with a barrier and an adjustable barrier group.

Heat shrinkable shank is a kind of shank that needs to be heated to expand the shank and expand the inner hole of the shank to accommodate the tool. When the shank is cooled, the inner hole will shrink to fix the tool and make the shank and tool Can be firmly combined.

Heat-shrinkable toolholders are usually heated by a toolholder heater. Common toolholder heaters generally use electromagnetic induction or hot air heating. Traditional hot-air toolholder heaters are equipped with a hot air gun and a heating cover; Wherein, the hot air gun can output hot air; the heating cover has opposite upper and lower ends, and a heating space extending above and below the heating cover. The hot air gun can output hot air to the heating space, and set the knife. However, the upper and lower ends of the heating hood of the existing hot air type knife shank heater lack a structure that blocks the heating space from the outside of the heating hood. Therefore, when the hot air gun outputs hot air to the heating space to perform knife setting When the rod is heated, hot air will directly flow out from the upper and lower ends of the heating cover, which causes a problem of low heating efficiency. It can be seen that the structure of the heating cover of the existing hot air knife rod heater has made progress and improvement. Space.

In order to solve the problem that the upper and lower ends of the heating hood of the existing hot air type knife bar heater have no barrier structure, the heating efficiency is not high. This creation proposes a knife bar heater with an adjustable heating shield barrier structure. The heating shield is provided with a barrier and an adjustable barrier group, which can control the flow of hot air from the heating shield to achieve the purpose of stable heating.

The cutter bar heating machine with adjustable heating hood barrier structure proposed by this creative solution to the technical problem includes a hot air gun assembly including a hot air gun, the hot air gun including a hot air outlet, and a heating hood which combines The hot air gun includes a heating space, a first through hole and a second through hole. The heating space is provided along the extending direction inside the heating cover and forms the first through hole and the second through hole. The heating space communicates with the hot air outlet; a blocking member, the blocking member includes a blocking member body and a through hole penetrating the blocking member body, and the blocking member body is detachably coupled to the heating cover and Capable of blocking the first through-hole and communicating the through-hole with the first through-hole; and an adjustable blocking group combined with the heating cover and including a two-leaf group capable of blocking the second through-hole, and A toggle member is rotatably disposed between the two blade groups, each blade group includes two or more blades, the two or more blades are arranged around the extension direction, and the two or more blades are arranged Can receive the dial The pushing member and to swing toward or away from each other.

In the cutter bar heater with adjustable heating hood barrier structure, the shifting member includes two or more first guide posts and two or more circularly distributed around the extending direction as a center. Each of the first guide post and each second guide post protrude in opposite directions; the leaves of each blade group include a guide hole having a long arc shape, and one of the leaves of the blade group A guide hole sleeve is provided on one of the first guide posts of the toggle member, and each blade of the other blade group is placed on one of the second guide columns of the toggle member by the provided guide hole sleeve.

In the knife bar heating machine with adjustable heating hood blocking structure, the two blade groups are arranged at an angle and offset.

In the knife bar heater with an adjustable heating hood barrier structure, the adjustable barrier group includes a container, the shifting member and the two blades are assembled in the container, and the switch The moving member includes a toggle protrusion protruding from the container.

The knife rod heater with the adjustable heating hood barrier structure, wherein the container shell includes two or more first pivot posts and two or more of the first and second pivot posts distributed in a circle around the extension direction. A second pivot post, each first pivot post and each second pivot post protruding opposite to each other; the blades of each blade group include a pivot hole, wherein each blade of the blade group is sleeved in the container with the provided pivot hole; One of the first pivot posts of the shell and the other blades of the other blade group are sleeved on one of the second pivot posts of the container with the pivot holes provided.

In the knife bar heater with the adjustable heating hood barrier structure, the blades of each blade group are set to two, and the number of the first guide post and the second guide post of the toggle member is correspondingly set to two. The number of the first pivot post and the second pivot post of the toggle member is correspondingly set to two.

In the knife rod heater with the adjustable heating hood barrier structure, the heating hood includes a U-shaped guide groove, which is adjacent to the first through opening; the barrier body can The guide groove is inserted to be detachably combined with the heating cover.

The improvement of the efficacy obtained by the technical means of this creation is that the knife bar heater with adjustable heating hood barrier structure of this creation is provided with removable barriers and adjustable adjustable barrier groups. Covering the first opening of the heating cover, the blades of the blade group of the adjustable blocking group can cover the second opening of the heating cover, and the insulation air is prevented from flowing out of the first and second openings of the heating cover, which can enhance the creation The heating efficiency of the cutter bar; furthermore, the blocking member can be replaced, so that the size of the through hole of the blocking member can be adjusted according to the size and type of the cutter, and the blades of the blade group of the adjustable blocking group can approach or leave each other. This creation can control the flow of hot air from the first and second openings of the heating hood to achieve the purpose of stable heating.
