Abstract

A kind of center veneer lathe that has with automatic bar pressing includes clamp system, feed mechanism, bar-pressing mechanism, it is characterised in that the bar-pressing mechanism is divided into pressure thick stick and pushes thick stick, and upper pressure thick stick is located at the surface of log, and pushing thick stick is located at the obliquely downward of log.The utility model is novel in design, clever structure, by upper and lower thick stick to the uniform pressurization of the small wooden diameter round log, ensure that the stabilization of log jerk value during rotary-cut, keeps the leather thickness of back-out uniform, and surface smoothness is good, reduces work difficulty, saves artificial.

Description

It is a kind of to have center veneer lathe with automatic bar pressing

Technical field

The utility model belongs to wood processing machinery equipment, and specifically a kind of thick stick with pressure has center veneer lathe.

Background technology

It is veneer processing first in wood based panel manufacturing machinery's process equipment, there are two types of different equipment for veneer machining tool.One Kind is that have center veneer lathe, and another kind is exactly card-less rotary cutter.There is center veneer lathe to fix the center of round log by chuck, passes through Drive round log rotation, feed screw that feeding is pushed to complete rotary-cut.Currently, well known have center veneer lathe that cannot process log diameter Below at 0.2 meter, the reason is that in rotary-cut round log, the too small easy bounce of the wooden diameter causes slab became uneven even, flatness and Finish is unstable, causes product unqualified, and using effect cannot meet the needs of client, therefore related peeler urgent need wants one Kind automatic pressurizing mechanism carrys out stably and controllable pressing pressure, manually presses in the past to ensure to beat, but is difficult to control, and takes a lot of work, expense When, it is laborious, labor intensity is big, and ideal effect is not achieved.

Invention content

In order to overcome it is existing have the center veneer lathe rotary-cut small wooden diameter round log when round log bounce that generates caused by a series of problems, What the utility model provided a kind of new belts automatic bar pressing has center veneer lathe, can prevent from justifying when the rotary-cut small wooden diameter round log Wood bounce so that the leather uniformity, surface smoothness achieve the effect that customer satisfaction.

Technical solution adopted by the utility model to solve its technical problems is：Have center veneer lathe clamp leading screw just on Side and side-lower install additional and push thick stick, by chain connection the feeding of knife platform, upper and lower pressure bar feeding synchronization onwards come so that small wood Upper and lower pressure bar synchronizes elongation with the reduction of the wooden diameter during diameter round log rotary-cut, and lower compression roller can remain phase in guarantee On same pressure top to round log, and then in a certain range jerk value control of round log during rotary-cut.

The utility model has the beneficial effects that pressure is uniform, stablizes in rotary-cut minor diameter round log and do not beat, slab surface Flat smooth, thickness are uniform.

Specific implementation mode

It show same equipment shown in Fig. 1, Fig. 2 and Fig. 3, is a kind of to have center veneer lathe with automatic bar pressing.Originally there is card rotation The machine of cutting includes the rotation clamp system of main frame, knife platform feed mechanism, bar-pressing mechanism, round log.The knife platform feed mechanism includes Feed screw 22, nose bar 20 and knife platform 21.The knife platform 21 is located at the front of log 17, on arrived equipped with rotary-cut.The nose bar position Right over knife platform, play the role of being oriented to pressure skin.The pressure lever mechanism includes upper pressure thick stick set 15, upperpush rod 16, upper pressure thick stick roller Son 23 pushes thick stick set 25, down-pressed pole 18, lower compression roller 24.The round log clamp system includes clamping leading screw 26 and clamping F.F. skin Belt wheel.The upper and lower compression bar 16,18 is sleeved in upper and lower pressure thick stick set 15,25, and upperpush rod 16 is located at right over log 17, down-pressed pole 18 are located at the obliquely downward of log 17.

When equipment works, clamping motor 3 drives the clamping feeding of leading screw 26 to block round log both ends by clamping belt wheel 2.Greatly The driving of bevel pinion 1 clamps the rotation of 26 clamping log 17 of lead screw, is driven by the way that sprocket wheel 8,10,12,13,14 is synchronous with feed screw 22 Moving knife platform 21 is fed and upper pushing thick stick adds the reality of log pressure.Pass through above-mentioned transmission mechanism so that upper lower compression roller can revolve It remains that constant pressure is pressed on round log 26 during circle of contact wood, and then reaches ideal rotary-cut effect.

When the wooden diameter is thinner, needs are pressurizeed with pressure thick stick, and the fast stepper motor of pressure thick stick 9 passes through compression bar F.F. belt pulley 11 Drive sprocket 12,13,14 drives upper and lower compression bar 16,18 in turn, and pressure roller 23 and lower compression roller 24 is made to be pressed onto on round log.

Claims

1. a kind of having center veneer lathe, including clamp system, feed mechanism, bar-pressing mechanism with automatic bar pressing, it is characterised in that：Institute It states bar-pressing mechanism and is divided into pressure thick stick and down-pressed pole, upper pressure thick stick is located at the surface of log, pushes the obliquely downward that thick stick is located at log.

A kind of there is center veneer lathe with automatic bar pressing 2. according to claim 1, it is characterised in that：The compression bar of upper and lower pressure bar The direction being oriented to along compression bar set moves, and there are two short pressure rollers for upper pressure thick stick, push thick stick and there was only a long pressure roller.

A kind of there is center veneer lathe with automatic bar pressing 3. according to claim 1, it is characterised in that：Two upperpush rod leading portions There are one pressure roller, two down-pressed pole tops to push roll end with a root long and connect for each installation.
