Abstract
The utility model provides a timber cutting apparatus comprising a timber roller (5), a pinch roller (4), a vertical elevating system braking the pinch roller to perform vertically elevating motions and a fixing rack (6). The pinch roller (4) is arranged just over the timber roller (5); the timber roller (5) is connected to the vertical elevating system; the vertical elevating system is fastened on the fixing rack (6); and the fixing rack (6) is fixedly connected to a timber cutting machine or the ground. By the use of the vertical elevating system, compact and separation between the pinch roller and the timber are achieved, so that planks like light timber, thin board or plank with poor cutting performance cannot slide relative to the timber during cutting operation, thereby accomplishing cutting work according to technological requirements.
Description
Technical field
The utility model relates to a kind of timber process equipment, particularly relates to a kind of timber cutter sweep.
Background technology
The advantage such as that wooden boards has is lightweight, strength ratio is high, good springiness, shock-resistant, unity and coherence in writing tone enrich attractive in appearance, handling ease has resource regeneration simultaneously, and wooden boards all occupies an important position in national economy to the present from ancient times.The wooden boards processing industry is mainly processed with mechanical means take wooden boards as raw material.In existing timber circular sawing machine, on the timber roller that timber is placed on setting, roller rotates drive timber and moves to the circular saw head, completes the straight cuts of timber during through the circular saw head.Yet, such as lightweight timber, thin plate timber due to lightweight, it is poor that the maximum static friction force that is produced by the gravity of timber own between itself and timber roller can not overcome Cutting Drag or the cutting performance of timber own of itself and circular saw head, the maximum static friction force that can produce on the timber roller greater than the gravity of timber own with respect to circular saw head Cutting Drag, cause timber with respect to the timber wheel slip, timber can not be completed cutting by technological requirement.
The utility model content
For solve above-mentioned such as lightweight timber, thin plate timber due to lightweight, perhaps the cutting performance of timber own is poor, be not enough to overcome the problem of the cutting resistance between timber and circular saw head in the maximum static friction force power that produces on the timber roller by the gravity of timber own, the utility model provides a kind of timber cutter sweep.
For achieving the above object, the utility model is by the following technical programs: a kind of timber cutter sweep, comprise the timber roller, also comprise pinch roller, brake vertical lifting system and fixed mount that pinch roller is done the vertical lifting motion, described pinch roller be arranged on the timber roller directly over, described timber roller is connected in the vertical lifting system, and described vertical lifting system is fixed on fixed mount, and described fixed mount is fixedly connected on timber cutting bed vise frame or on the ground large.
Driving pinch roller by the vertical lifting system presses down, make the wooden boards that is placed between timber roller and pinch roller produce larger normal pressure to the timber roller, increase the maximum static friction force of wooden boards and timber roller, thereby make the frictional force between wooden boards and timber roller can overcome timber and circular saw head Cutting Drag, complete smoothly cutting; System drives the pinch roller rising when vertical lifting, forms the space between pinch roller and timber roller, completes the replacing of wooden boards.
As preferably, described pinch roller employing center is provided with the nylon wheel of bearing.Pinch roller employing center is provided with the nylon wheel of bearing, and the bearing of setting can reduce the resistance that pinch roller moves timber as far as possible, and nylon wheel has good wearability and intensity, satisfies to be subjected to force intensity and durable.
As preferably, described vertical lifting system comprises cylinder, horizon bar and bearing rod, the inner ring interference fit of the bearing that arranges on described bearing rod one end and pinch roller, and the other end is welded on the side of described horizon bar; The upper surface of described horizon bar is connected with the external part end face of cylinder piston rod; The other end that described cylinder is connected with horizon bar relatively is fixedly connected with fixed mount.Employing comprises the jacking system processing of cylinder, horizon bar and bearing rod and easy to manufacture, easy to maintenance.
As preferably, described cylinder adopts the single-cylinder single-acting cylinder.To the cylinder air feed, to cylinder exhaust, described horizon bar, bearing rod and pinch roller rise under the elastic force effect of cylinder piston other end spring when realizing that pressure head rises when realizing that pressure head presses down.Namely select simple, easy operating cylinder form satisfy technological requirement.
Further, described pinch roller axial direction is parallel with the axial direction of timber roller.This be provided with reason guarantee pinch roller when pressing down with timber between for line contacts, can avoid under required normal pressure because of pinch roller and the too small damage timber of timber contact area.
Further, the material of described horizon bar and bearing rod is the 20# steel.20# steel good processability, low price.
The utility model compared with prior art has following beneficial effect:
A kind of timber cutter sweep that the utility model provides, by the vertical lifting system that arranges, the compression that can realize pinch roller and timber with separate, when compressing by being applied to the normal pressure on plank, make plank with respect to larger maximum static friction force is arranged between timber, make the frictional force of timber and roller can overcome the circular saw head resistance that motion produces to timber and the force of rolling friction of pinch roller, making such as the poor plank of lightweight timber, thin plate or cutting performance can with respect to the timber wheel slip, not make timber complete cutting by technological requirement when cutting.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of a kind of timber cutter sweep of the present utility model;
Fig. 2 is the left view of a specific embodiment of a kind of timber cutter sweep of the present utility model.
Name corresponding to graphical indicia is called: 1, cylinder, 2, horizon bar, 3, bearing rod, 4, pinch roller, 5, the timber roller, 6, fixed mount.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment:
Embodiment 1:
As Fig. 1, a kind of timber cutter sweep that the utility model provides, comprise timber roller 5, also comprise pinch roller 4, brake vertical lifting system and fixed mount 6 that pinch roller is done the vertical lifting motion, described pinch roller 4 be arranged on timber roller 5 directly over, described timber roller 5 is connected in the vertical lifting system, and described vertical lifting system is fixed on fixed mount 6, and described fixed mount 6 is fixedly connected on timber cutting bed vise frame or on the ground large.
Driving pinch roller by the vertical lifting system presses down, make the wooden boards that is placed between timber roller and pinch roller produce larger normal pressure to the timber roller, increase the maximum static friction force of wooden boards and timber roller, thereby make the frictional force between wooden boards and timber roller can overcome timber and circular saw head Cutting Drag, complete smoothly cutting; System drives the pinch roller rising when vertical lifting, forms the space between pinch roller and timber roller, completes the replacing of wooden boards.
Embodiment 2:
The present embodiment further improves below having made on the basis of embodiment 1: as shown in Figure 1, described a kind of timber cutter sweep of the present utility model, comprise pinch roller 4, described pinch roller 4 is set to the nylon wheel that the center is provided with bearing, described bearing adopts the deep groove ball bearing with dust cap, and the deep groove ball bearing low price, coefficient of friction is very little and can bear larger axial load; The dust that the dust cap that arranges is conducive to stop the timber cutting to produce enters between bearing outer ring and inner ring, extends bearing service life.
