Technical Field

The utility model relates to a peeler technical field specifically is a no calorie of axle peeler cam activity sword seam device.

Background

With the continuous development of society, the demand for plywood is also higher and higher, and the rotary cutter is the main equipment of plywood panel production, and it is vital to improving the quality of rotary cutter panel to improve the quality of plywood.

The raw wood processed by the rotary cutter has great difference in softness, hardness, humidity and the like, and some raw wood needs movable blade points and some raw wood needs dead knife seams. Some eccentric wheels are adopted to adjust the knife gap, and quality problems can occur in the uniformity of the plate due to the fact that the feeding speed of the plate is not matched with the feeding speed of the log.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a no calorie of axle peeler cam activity sword seam device has changed the clearance between single roller and the rotary-cut sword, and the curve of cam matches with the speed of feeding, and the size of sword seam is along with seeing feed rate balanced change completely for the power that the log received is balanced, and has reduced the third load power, has guaranteed the degree of consistency of panel, can solve the problem among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme:

the cam movable knife gap device of the veneer lathe without the clamping shaft comprises a knife rest, wherein a support is installed at the top end of the knife rest, a single roller box is installed at the top end of the support through screws, the single roller box is connected with a push rod in a transmission mode, the push rod is connected with a cam through swinging of a rocker arm, the cam is connected with a bearing in the support in a high-pair mode, one end of the support is installed on the knife rest through a pin shaft, a single roller is further installed at one end of the support, and a rotary cutter installed on the knife rest is arranged below the single roller in an inclined mode.

Furthermore, a transmission mechanism in the single-roller box is in transmission connection with the push rod.

Furthermore, the knife point of the rotary cutter is close to the single roller.

Further, the rotary cutter is fixedly arranged on the cutter platform.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the cam movable knife gap device of the veneer lathe without the clamping shaft has the advantages that the push rod drives the rocker arm to rotate around the central axis of the cam, the curve of the cam is gradually raised along with the rotation of the cam to jack up the bearing, so that the bracket, the single roller box and the single roller cylinder simultaneously rotate around the pin shaft, the gap between the single roller cylinder and the rotary cutter is changed, the knife gap is gradually reduced when the single roller box is fed and advances, the knife gap is gradually increased when the single roller box is retreated, the rotary lathe can randomly switch (dead knife gap or movable knife gap) according to the rotary cutting of logs made of different materials, the size of the knife gap is completely changed along with the feeding speed due to the matching of the curve of the cam and the feeding speed, the force borne by the logs is balanced, one-third load force is reduced, and the uniformity of the plates is guaranteed.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a cam; 2. a bearing; 3. a support; 4. a single roll box; 5. a pin shaft; 6. a single roller; 7. A rotary cutter; 8. a tool post; 9. a push rod.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a cam movable knife gap device of a spindle-free rotary cutter comprises a knife rest 8, a support 3 is mounted at the top end of the knife rest 8, a single roller box 4 is mounted at the top end of the support 3 through screws, the single roller box 4 can synchronously move when the support 3 swings, a transmission mechanism in the single roller box 4 is in transmission connection with a push rod 9, the push rod 9 is moved by feeding of the single roller box 4, the push rod 9 is connected with a cam 1 through a rocker 10 in a swinging mode, the rocker 10 is driven by the push rod 9 to rotate around the central axis of the cam 1, the cam 1 is in high-pair connection with a bearing 2 in the support 3, the curve of the cam 1 gradually rises along with the rotation of the cam 1 to jack up the bearing 2, one end of the support 3 is mounted on the knife rest 8 through a pin 5, the support 3 can rotate around the pin 5, a single roller 6 is further mounted at one end of the support 3, and, The single roller 6 rotates around the pin shaft 5 simultaneously, the rotary cutter 7 fixedly installed on the cutter table 8 is arranged obliquely below the single roller 6, the cutter point of the rotary cutter 7 is close to the single roller 6, and after the single roller 6 is driven to rotate, the gap between the single roller 6 and the rotary cutter 7 is changed, when the single roller box 4 advances in a feeding mode, the cutter gap gradually becomes smaller, and when the single roller box 4 retreats, the cutter gap gradually becomes larger.

The working principle is as follows: the push rod 9 is moved by the feeding of the single roller box 4, the push rod 9 drives the rocker arm 10 to rotate around the central axis of the cam 1, the bearing 2 is jacked up by the curve of the cam 1 along with the gradual rising of the rotation of the cam 1, the bracket 3, the single roller box 4 and the single roller 6 rotate around the pin shaft 5 simultaneously by the gradual rising of the bearing 2, so that the gap between the single roller 6 and the rotary cutter 7 is changed, the cutter gap is gradually reduced when the single roller box 4 is fed forwards, and the cutter gap is gradually increased when the single roller box 4 is backwards moved.

In summary, the following steps: according to the cam movable knife seam device of the veneer lathe without the clamping shaft, the push rod 9 drives the rocker arm 10 to rotate around the central axis of the cam 1, the curve of the cam 1 gradually rises along with the rotation of the cam, so that the bearing 2 is jacked up, the bracket 3, the single roller box 4 and the single roller 6 simultaneously rotate around the pin shaft 5, the gap between the single roller 6 and the rotary cutter 7 is changed, the knife seam is gradually reduced when the single roller box 4 is fed and moved forward, the knife seam is gradually enlarged when the single roller box 4 is moved backward, the rotary lathe can randomly switch (dead knife seam or movable knife seam) according to rotary cutting logs of different materials, and because the curve of the matching of the cam 1 and the feeding speed, the size of the knife seam is completely changed in a balanced manner along with the feeding speed, the force borne by the logs is balanced, one-third load force is reduced, and the uniformity of the plates is ensured.
