Description

Technical Field

[0001] This invention relates to the field of paper-faced gypsum board technology, and more specifically to a gypsum board crushing and separating device for use in a universal board production line. Background Art

[0002] On production lines that use gypsum board as the substrate to manufacture universal boards, the substrate needs to be cut to full dimensions. To ensure sustainable resource utilization, the gypsum and paper surfaces of the remaining material need to be separated for subsequent reuse in gypsum board production.

[0003] In existing technologies, methods for separating gypsum board from paper mainly fall into two categories. The first category involves first crushing the gypsum board and then sieving the crushed gypsum board. However, this method results in some paper scraps being mixed into the gypsum powder, severely affecting the purity of the gypsum refining and recycling, leading to low-quality recycled gypsum. The second category uses rollers to crush the gypsum in the middle of the gypsum board to achieve separation from the paper. However, this method results in a large amount of gypsum failing to detach from the paper surface, making the separation effect less than ideal. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention designs a gypsum board crushing and separation device for a multi-purpose board production line, comprising: a support frame; a crushing and separation chamber, mounted on the support frame, for crushing gypsum board scraps from the multi-purpose board production line; a material inlet, located at the top of the crushing and separation chamber, through which gypsum board scraps from the multi-purpose board production line enter the crushing and separation chamber; a material outlet, located at the bottom of the crushing and separation chamber, through which the crushed gypsum board scraps from the multi-purpose board production line are discharged; and a motor, mounted on the support frame and connected to the crushing and separation chamber, for providing power to the crushing and separation chamber for crushing the gypsum board scraps from the multi-purpose board production line.

[0005] Preferably, the crushing and separation chamber crushes the gypsum board residue on the universal board production line through a roller set, wherein the roller set includes 2n+1 pairs of rollers, where n is a positive integer.

[0006] Preferably, the roller set includes: a first pair of rollers, which is disposed below the material inlet; and a second-level roller set, which includes 2n pairs of rollers, where n is a positive integer, and the 2n pairs of rollers are symmetrically and evenly disposed on both sides below the first pair of rollers.

[0007] Preferably, a separator is provided between the first pair of rollers and the second pair of rollers.

[0008] Preferably, the secondary roller group consists of two pairs of rollers, namely the second pair of rollers and the third pair of rollers, which are symmetrically arranged on both sides below the first pair of rollers.

[0009] Preferably, a synchronization assembly is provided outside the crushing and separation chamber, and there are two sets of synchronization assemblies. One set of synchronization assemblies is used to control the left roller shafts of the first pair of rollers, the second pair of rollers and the third pair of rollers to rotate synchronously, and the other set of synchronization assemblies is used to control the right roller shafts of the first pair of rollers, the second pair of rollers and the third pair of rollers to rotate synchronously.

[0010] Preferably, there are two motors, and the two sets of motors are connected to two sets of synchronization components respectively.

[0011] Preferably, the synchronization components include a timing pulley and a timing belt.

[0012] Preferably, a dustproof curtain is installed at the material inlet.

[0013] Preferably, the motor is equipped with an overload protection controller.

[0014] Compared with the closest prior art, the beneficial effects of the present invention are as follows:

[0015] 1. After the gypsum board of the present invention is crushed by the first pair of rollers, it is divided into two parts by a separator. One half enters the secondary roller group on one side below the first pair of rollers, and the other half enters the secondary roller group on the other side below the first pair of rollers. This allows the gypsum in the middle of the gypsum board to directly contact the roller shaft, eliminating the need to crush the gypsum in the middle of the gypsum board through paper, thus enhancing the crushing effect.

[0016] 2. When the overload protection controller of this invention detects that the motor current is too high, it automatically switches the rotation direction of the motor to push the gypsum board residue back a small distance. At this time, the overload protection controller automatically switches the rotation direction again to crush the residue, thus achieving stable crushing of the residue. Attached Figure Description

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] like Figures 1-6 As shown, the present invention provides a gypsum board crushing and separating device for a universal board production line, comprising: a support frame 1; a crushing and separating chamber 2, installed on the support frame 1, for crushing gypsum board scraps from the universal board production line; a material inlet 3, located at the top of the crushing and separating chamber 2, through which gypsum board scraps from the universal board production line enter the crushing and separating chamber 2; a material outlet 4, located at the bottom of the crushing and separating chamber 2, through which the crushed gypsum board scraps from the universal board production line are discharged; and a motor 5, installed on the support frame 1 and connected to the crushing and separating chamber 2, for providing power to the crushing and separating chamber 2 for crushing the gypsum board scraps from the universal board production line.

[0027] Preferably, the crushing and separating chamber 2 crushes the gypsum board residue on the universal board production line using a roller set, wherein the roller set includes 2n+1 pairs of rollers, where n is a positive integer. Using multiple pairs of rollers to crush the gypsum board avoids the situation where the gypsum in the middle of the gypsum board cannot be completely crushed in one go, ensuring that the gypsum separates from the paper surface and enhancing the separation effect between the gypsum and the paper.

[0028] Preferably, the roller set includes: a first pair of rollers 7, which is disposed below the material inlet 3; and a second-stage roller set, which includes 2n pairs of rollers, where n is a positive integer, and the 2n pairs of rollers are symmetrically and evenly disposed on both sides below the first pair of rollers 7.

[0029] Preferably, a separator 10 is provided between the first pair of rollers 7 and the secondary pair of rollers. After the gypsum board is crushed by the first pair of rollers 7, it is divided into two parts by the separator 10. One half enters the secondary pair of rollers on one side below the first pair of rollers 7, and the other half enters the secondary pair of rollers on the other side below the first pair of rollers 7. This allows the gypsum in the middle of the gypsum board to directly contact the roller shaft, eliminating the need to crush the gypsum in the middle of the gypsum board through paper, thus enhancing the crushing effect.

[0030] Preferably, the secondary roller group consists of two pairs of rollers, namely the second pair of rollers 8 and the third pair of rollers 9, which are symmetrically arranged on both sides below the first pair of rollers 7.

[0031] Preferably, a synchronization component 6 is provided outside the crushing and separation chamber 2, and there are two sets of synchronization components. One set of synchronization components 6 is used to control the left roller shafts of the first pair of rollers 7, the second pair of rollers 8 and the third pair of rollers 9 to rotate synchronously, and the other set of synchronization components 6 is used to control the right roller shafts of the first pair of rollers 7, the second pair of rollers 8 and the third pair of rollers 9 to rotate synchronously.

[0032] Preferably, there are two motors 5, and the two sets of motors 5 are respectively connected to two sets of synchronization components 6.

[0033] Preferably, the synchronization component 6 includes a synchronization pulley and a synchronization belt. Alternatively, a synchronization gear and a synchronization chain may be used.

[0034] Preferably, a dust curtain is installed at the material inlet 3. The dust curtain effectively prevents gypsum powder in the crushing and separation chamber 2 from entering the air, thus preventing air pollution.

[0035] Preferably, the motor 5 is equipped with an overload protection controller. The main components of gypsum board scrap are gypsum and facing paper. In particular, gypsum is sticky and will fill and squeeze the rollers during the crushing process, causing the instantaneous current of the motor to be too high. At this time, the overload protection controller plays a role: when the overload protection controller detects that the motor current is too high, it automatically switches the rotation direction of the motor, pushing the gypsum board scrap back a small distance. Then, the overload protection controller automatically switches the rotation direction again to crush the scrap, thus achieving stable crushing of the scrap.
