Description

Technical Field

[0001] The invention relates to the field of plywood processing, in particular to a scrap material crushing device for plywood processing. Background Art

[0002] Plywood is a three-layer or multi-layer plate-like material made by cutting wood segments into veneers or planing wood into veneers, and then gluing them with adhesives. Usually, an odd number of veneers are used, and the fiber directions of adjacent veneers are glued perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major artificial boards. A group of veneers are usually assembled and glued according to the wood grain directions of adjacent layers that are perpendicular to each other. Usually, its surface board and inner layer board are symmetrically arranged on both sides of the center layer or the core. The scraps after plywood processing need to be crushed and reused; when the existing plywood scrap crushing device is in use, usually two sets of crushing rollers are used to rotate in opposite directions to crush the plywood scraps, and all the larger scraps in the plywood scraps are crushed. However, some of the scraps after crushing still do not meet the crushing requirements. A filter screen is installed in the existing crushing device to filter out the scraps with increased volume after crushing. At this time, the guide mechanism will filter the scraps above the filter screen. The material is introduced into the secondary crushing mechanism, and the filter is usually installed at an angle so that the scraps above the filter can slide down along the inclined surface into the secondary crushing mechanism. The secondary crushing mechanism is used to perform secondary crushing on these larger scraps. During use, in order to prevent the filter from being blocked, a vibration motor is used to vibrate the filter to prevent the filter from being blocked, or a driving mechanism is used to drive the scraper to continuously clean the filter to prevent the filter from being blocked. However, when the scraps on the filter enter the secondary crushing mechanism, blockage is likely to occur. Secondly, when a vibration motor is used to vibrate the filter, the vibration motor needs to be installed on the filter, which will cause the vibration motor to be installed in the inner cavity of the box. The heat generated by the vibration motor working for a long time is not easy to dissipate. If the scraper is used to move to clean the filter, the scraper will rub against the filter for a long time, which is easy to cause wear of the filter. For this reason, we propose a scrap material crushing device for plywood processing. Summary of the invention

[0035] A discharge hopper 30 is fixedly installed at the bottom of the box body 1, and the discharge hopper 30 is interconnected with the inner cavity of the box body 1; when in use, the scraps in the cylinder 2 pass through the through hole opened on the cylinder 2 and are discharged through the discharge hopper 30.

[0036] The working principle of the present invention is as follows: when in use, the plywood scraps are poured into the crushing box 6 from the feed hopper at the top of the crushing box 6, and at the same time, the motor 20 is started and the two groups of crushing rollers 20 are driven to rotate in opposite directions under the transmission of the two groups of mutually meshing gears 3 21. The two groups of crushing rollers 20 rotate in opposite directions to crush the plywood scraps, especially the plywood scraps with larger volumes. The scraps crushed by the crushing rollers 20 will fall on the dividing rollers 10, and the scraps will enter the dividing trough 11 opened by the dividing rollers 10; at the same time, the speed reducer 14 is started to drive the cutting shaft 4 to rotate, and the cutting shaft 4 rotates and drives the rotating shaft 7 to rotate under the transmission of the two groups of sprockets 12 and the chain 13. The rotation of the rotating shaft 7 drives the dividing roller 10 to rotate. The rotation of the dividing roller 10 will discharge the scraps in the dividing trough 11 and discharge them into the feeding pipe 5, and are blocked by the dividing roller 10, so that the crushed scraps in the crushing box 6 are gradually added to the feeding pipe 5;

[0037] The rotating shaft 7 rotates and under the transmission of the two sets of sprocket wheels 3 26 and the chain 3 27, the stirring shaft 25 is driven to rotate, and the rotation of the stirring shaft 25 drives the multiple sets of stirring blades 28 to rotate. The rotation of the multiple sets of stirring blades 28 will continuously stir the scraps above the dividing roller 10, preventing the scraps from accumulating between the dividing roller 10 and the crushing roller 20, and preventing the accumulation of scraps from affecting the dividing roller 20 from unloading the scraps;

[0038] The scraps entering the feed pipe 5 will slide down into the cylinder 2. At this time, the rotation of the cutting shaft 4 will drive the multiple sets of cutting blades 24 to rotate. The rotation of the multiple sets of cutting blades 24 will cut and crush the scraps in the cylinder 2. The scraps in the cylinder 2 can only pass through the through holes opened on the cylinder 2 after they reach a certain volume, and then can be discharged from the discharge hopper 30.

[0039] During use, the cutting shaft 4 rotates and under the transmission of the two sets of sprocket wheels 2 16 and the chain 2 17, the rotating rod 15 will be driven to rotate, the rotating rod 15 will drive the gear 18 to rotate, the gear 18 will drive the gear 2 19 to rotate, the gear 2 19 will drive the cylinder 2 to rotate, and the cylinder 2 and the cutting shaft 4 rotate in opposite directions. The rotation of the cylinder 2 can continuously stir the scraps in the cylinder 2, and can better throw the scraps of suitable size in the cylinder 2 out of the cylinder 2 through the through holes on the cylinder 2. When the cylinder 2 rotates continuously, the scraps in the cylinder 2 will not easily block the through holes on the cylinder 2. At the same time, the rotation of the rotating shaft 7 will drive the elliptical wheel 9 to rotate. During the rotation process, the elliptical wheel 9 can push the auxiliary plate 801 upward, and the upward movement of the auxiliary plate 801 will drive the elastic rod 802, the guide rod 804 and the rubber protection block 803 to move upward. At this time, the spring 806 will be stretched. As the elliptical wheel 9 rotates, the stretched spring 806 will be reset, and then the elastic rod 802 and the rubber protection block 803 will be driven to move downward and reset. The rubber protection block 803 will touch the cylinder 2 when it moves downward. Due to the special shape of the elliptical wheel 9, each rotation of the elliptical wheel 9 will cause the rubber protection block 803 to move downward twice to touch the cylinder 2.

[0040] Multiple groups of rubber protection blocks 803 continuously touching the cylinder 2 will cause the cylinder 2 to vibrate, which can shake off the scraps blocked in the through holes on the cylinder 2, and in the process of the rubber protection blocks 803 continuously touching the cylinder 2, the cylinder 2 also rotates continuously, so that the rubber protection blocks 803 touch and hit different positions of the cylinder 2, and then touch and vibrate different positions of the cylinder 2, thereby ensuring that the scraps in the through holes at different positions of the cylinder 2 can be shaken off; and the rubber protection blocks 803 touch and hit different positions of the cylinder 2, which can avoid the rubber protection blocks 803 touching and hitting the same position of the cylinder 2 for a long time, and can reduce damage to the cylinder 2. Secondly, the rubber protection blocks 803 are made of rubber and have good elasticity. Using the rubber protection blocks 803 to touch and hit the cylinder 2 can play a protective role.

[0041] It should be noted that when the device of the present invention is in use, it needs to be connected to a suitable external power supply and controller. The external power supply provides power support for the operation of the motor 20 and the reducer 14. The operation of the motor 20 and the reducer 14 can be controlled by the external controller, and the reducer 14 needs to adopt a reducer that meets the driving requirements of the device of the present invention.

[0042] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
