Description

Technical Field

[0001] The utility model belongs to the technical field of woodworking band saw machines and related accessories, in particular to a woodworking band saw brake mechanism. Background Art

[0002] With the development of society and technology, equipment in various fields has been greatly improved. A woodworking band saw is a sawing machine that uses a ring-shaped endless band saw blade as a sawing tool, which is wound around two saw wheels for unidirectional continuous linear motion to cut wood. The woodworking band saw is started by pressing the start button, and stopped by pressing the stop button or the emergency stop button. The downtime is about 30 seconds, so the downtime will be very long.

[0003] However, it still has the following disadvantages in actual use:

[0004] The existing woodworking band saw machine cannot be stopped quickly by pressing the stop or emergency stop button when encountering an emergency. To this end, we provide a woodworking band saw brake mechanism to solve the above problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a brake mechanism for a woodworking band saw, comprising a base and a body installed at the center of the upper surface of the base, a lower chamber body is arranged on one side of the bottom of the body, one side of the inner wall of the lower chamber body is movably connected with the inner side end of a connecting plate through a left end bolt, a mounting plate is arranged on the inner side of the outer wall of the connecting plate, a friction plate is arranged on the bottom of the mounting plate, and a tension spring is arranged above the middle part of the outer wall of the connecting plate.

[0008] The utility model is further configured that a band saw body is arranged inside the machine body, a hanging rod is fixedly connected to the outer side of the inner wall of the lower chamber body, and a lower wheel is installed inside the lower chamber body.

[0009] The utility model is further configured that a driving mechanism is arranged at the rear end of the lower wheel, and a middle bolt is installed at the middle part of the front end surface of the connecting plate.

[0010] The utility model is further configured that the outer end of the connecting plate is fixedly connected with a pedal, and both sides of the front end surface of the mounting piece are provided with mounting bolts at positions corresponding to the connecting plate.

[0011] The utility model is further arranged that the bottom end of the tension spring is sleeved on the outer wall of the middle bolt, and the top end of the tension spring is hung on the outer wall of the hanging rod.

[0012] The utility model has the following beneficial effects: the utility model provides a friction plate and a tension spring, and under the action of the elastic properties of the tension spring, the connecting plate can make a circular motion with the left end bolt as the center, and the friction plate can quickly brake the inner wall of the wheel hub of the lower wheel, so that the woodworking band saw machine can be quickly stopped within a few seconds. The utility model has a simple structure and a convenient and fast operation process, which can help the staff to quickly stop the woodworking band saw machine, and solves the problem that the existing woodworking band saw machine cannot be quickly stopped by the stop or emergency stop button when encountering an emergency.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0022] See also Figures 1 to 3 The utility model is a woodworking band saw brake mechanism, including a base 1 and a body 101 installed at the center of its upper surface, a lower chamber body 103 is arranged on one side of the bottom of the body 101, one side of the inner wall of the lower chamber body 103 is movably connected with the inner side end of a connecting plate 106 through a left end bolt, a mounting plate 108 is installed on the inner side of the outer wall of the connecting plate 106, a friction plate 2 is arranged at the bottom of the mounting plate 108, and a tension spring 3 is arranged above the middle of the outer wall of the connecting plate 106.

[0023] Specifically, a band saw body 102 is arranged inside the machine body 101, a hanging rod 1031 is fixedly connected to the outer side of the inner wall of the lower chamber body 103, a lower wheel 104 is installed inside the lower chamber body 103, a driving mechanism 105 is arranged at the rear end of the lower wheel 104, a middle bolt 1061 is installed in the middle of the front end face of the connecting plate 106, a pedal 107 is fixedly connected to the outer end of the connecting plate 106, mounting bolts 1081 are provided on both sides of the front end face of the mounting plate 108 at positions corresponding to the connecting plate 106, the bottom end of the tension spring 3 is sleeved on the outer wall of the middle bolt 1061, and the top end of the tension spring 3 is hung on the outer wall of the hanging rod 1031.

[0024] Furthermore, the machine body 101, the band saw body 102, the lower chamber body 103, the lower wheel 104, the driving mechanism 105, etc. are all prior arts, so they are not elaborated here. When braking is needed, the user applies force to the pedal 107, so that the outer end of the connecting plate 106 is subjected to force and rotates around the left end bolt at the inner edge, so that the connecting plate 106 moves in an arc downward, and the tension spring 3 can be stretched by the middle bolt 1061 and the hanging rod 1031, and the connecting plate 106 can be moved under the action of the elastic properties of the tension spring 3. The bottom of the mounting plate 108 is in an arc shape, and the curvature is the same as the curvature of the inner wall of the lower wheel 104. The mounting plate 108 can be quickly installed and removed by the mounting bolt 1081, so as to achieve the purpose of replacing the friction plate 2.

[0025] The operation process of this embodiment is as follows: the lower wheel 104 is driven to rotate by the driving mechanism 105 and the band saw body 102 is moved to work. After the operation is completed, the driving mechanism 105 stops driving the lower wheel 104, and at the same time, the staff steps on the pedal 107. The pedal 107 is forced to drive the outer end of the connecting plate 106 to move downward, wherein the inner end of the connecting plate 106 is movably connected to the inner wall of the lower chamber body 103 through the left end bolt, and a tension spring 3 is hung between the middle bolt 1061 on the connecting plate 106 and the hanging rod 1031 on the inner wall of the lower chamber body 103. Therefore, after the connecting plate 106 is forced to rotate downward with the left end bolt as the center, , and pull the tension spring 3. At the same time, the tilting rotation of the connecting plate 106 will drive the mounting plate 108 on its outer wall to move downward in an arc, and make the friction plate 2 at the bottom of the mounting plate 108 contact the inner wall of the lower wheel 104. At the same time, the friction plate 2 can quickly apply friction brake to the lower wheel 104, so that the woodworking band saw machine can be quickly stopped within a few seconds, and the pedal 107 is released. Under the action of the elastic performance of the tension spring 3, the relevant components can be reset, so that the friction plate 2 leaves the inner wall of the wheel hub of the lower wheel 104, and the braking process ends. It has a simple structure and a convenient and quick operation process, which can help the staff to achieve a quick shutdown of the woodworking band saw machine.
