Description

Technical Field

[0001] The present invention relates to gypsum board production equipment technology, in particular to a cutting device and a cutting knife adjustment device thereof. Background Art

[0002] In the gypsum board production line, various dry and wet materials and auxiliary materials are mixed by a mixer, sprayed between the upper and lower facing papers, and then pressed into gypsum boards of a certain thickness by an extrusion molding table. After the gypsum boards are formed and finally set, they are cut into required lengths (such as 2.0 meters, 2.4 meters, 3.0 meters, etc.) by a cutting machine, and then transported and dried by secondary controlled conveying equipment and drying equipment to produce qualified gypsum boards.

[0003] Due to the increase in production speed, according to the speed of gypsum board forming, the gypsum board is just final set from the forming to the cutting point, ensuring normal cutting. The cutting system is an important equipment and a link between the forming equipment and drying. In the normal production process, the cutting machine smoothly cuts through the misaligned bite of the upper and lower cutter teeth. When the cutter wears or there is a gap in the mechanical parts, the upper and lower cutter teeth cannot achieve accurate bite, which will cause the board to come out of the bevel, causing the board to overlap during transportation or the cutter cannot be cut directly, causing a malfunction and shutdown. When such a situation occurs, the position of the cutter teeth is roughly adjusted by the staff on duty each time by loosening the locking device and opening the tensioning device. This adjustment method is not precise enough on the one hand, and it is easy to cause a larger error after adjustment on the other hand. Therefore, it is very important to solve the precise adjustment of the upper and lower cutter teeth of the cutting machine.

[0004] This problem is also a common problem faced by some gypsum board production factories. This is a problem existing at the current technical level and also a shortcoming of the current technology. Summary of the invention

[0029] like Figure 1-6 As shown, an embodiment of the present application provides a cutting device 100, which is mainly used for cutting plates, such as gypsum boards.

[0030] like Figure 1 As shown, the cutter device 100 comprises a frame 1, at least one cutter assembly 2 mounted on the frame 1, and an adjusting device 3 mounted in cooperation with the cutter assembly 2 and adjusting the position of the cutter assembly 2.

[0031] like Figure 1 , Figure 3 As shown, the cutter assembly 2 includes a first cutter assembly 21 and a second cutter assembly 22. Figure 1 , Figure 6 As shown, the adjustment device 3 includes a first adjustment mechanism 31 which is installed in cooperation with the first cutter assembly 21 and adjusts the position of the first cutter assembly 21 , and a second adjustment mechanism 32 which is installed in cooperation with the second cutter assembly 22 and adjusts the position of the second cutter assembly 22 .

[0032] like Figure 1 , Figure 3 As shown, the first cutter assembly 21 includes a first cutter holder 210 and a cutter 211 connected to the first cutter holder 210. The first cutter holder 210 includes a first end 2101 mounted in cooperation with the first adjustment mechanism 31, a second end 2102 connected to the first cutter 211, and a first rotating portion 2103 located between the first end 2101 and the second end 2102 and rotatably connected to the frame 1.

[0033] Likewise, if Figure 1 , Figure 3 As shown, the second cutter assembly 22 includes a second cutter holder 220 and a second cutter 221 connected to the second cutter holder 220. The second cutter holder 220 includes a first end 2201 mounted in cooperation with the second adjustment mechanism 32, a second end 2202 connected to the second cutter 221, and a second rotating portion 2203 located between the first end and the second end and rotatably connected to the frame 1.

[0034] like Figure 3 As shown, during operation, the first cutter assembly 21 is located above the plate, and the second cutter assembly 22 is located below the plate. The first cutter 211 of the first cutter assembly 21 and the second cutter 221 of the second cutter assembly 22 engage with each other to cut the plate A.

[0035] like Figure 4 As shown, the first adjustment mechanism 31 includes a first drive mechanism 311 and a second drive mechanism 312. The first drive mechanism 311 and the second drive mechanism 312 are respectively arranged on opposite sides of the first end 2101 of the first tool holder 210 (see Figure 1 shown).

[0036] like Figure 5 As shown, the first driving mechanism 311 includes a first sliding member 3110, a first power conversion assembly 3111 for driving the first sliding member 3110 to move, and a first power member 3112. The first power conversion assembly 3111 includes a first main shaft 3111-a installed on the frame 1, a first slave shaft 3111-b (shown by the dotted line position in the figure) installed in cooperation with the first sliding member 3110, and a first adjusting wheel group 3111-c connecting the first main shaft 3111-a and the first slave shaft 3111-b.

[0037] The first main shaft 3111-a is connected to the first power member 3112, and the first slave shaft 3111-b is threadedly connected to the first sliding member 3110. The movement of the first slave shaft 3111-b drives the first sliding member 3110 to move. The first adjustment wheel group 3111-e is a bevel gear group. In this embodiment, the first power member 31110 adopts a first motor. The rotation of the first motor drives the first adjustment wheel group 3111-e to rotate, and the rotation of the first adjustment wheel group 3111-e drives the first sliding member 31110 to move. The first slave shaft 3111-b is perpendicular to the first main shaft 3111-a.

[0038] The second driving mechanism 321 includes a second sliding member 3210, a second power conversion assembly 3211 for driving the second sliding member 3210 to move, and a second power member 3212. The second power conversion assembly 3211 includes a second main shaft 3211-a installed on the frame 1, a second slave shaft 3211-b installed in cooperation with the second sliding member 3210, and a second adjustment wheel set 3211-e connecting the second main shaft 3211-a and the second slave shaft 3211-b. The second main shaft 3211-a is connected to the second power member 3212, and the second slave shaft 3211-b is threadedly connected to the second sliding member 3210. The second adjustment wheel set 3211-e is a bevel gear set. In this embodiment, the first adjusting wheel 3111-e group adopts a bevel gear, and the second adjusting wheel group 3211-e adopts a bevel gear group, so that the first sliding member 3112 and the second sliding member 3212 can move one toward the first tool holder 210 and the other toward a direction away from the first tool holder 210. In this embodiment, the second power member 3212 adopts a second motor. The rotation of the second motor drives the second adjusting wheel group 3211-e to rotate, and the rotation of the second adjusting wheel group 3211-e drives the second sliding member 3212 to move. The second main shaft 3211-a and the second slave shaft 3211-b are perpendicular, and the first slave shaft 3111-b and the second slave shaft 3211-b are located inside the first main shaft 3111-a and the second main shaft 3211-a, forming a gap for installing the first tool holder 210.

[0039] When adjusting the cutting depth of the first cutter 210, the first motor 3112 and the second motor 3212 rotate toward or away from each other, and the first drive mechanism 311 and the second drive mechanism 321 simultaneously drive the first cutter 211 to rotate clockwise or counterclockwise. During the movement, one of the first drive mechanism 311 and the second drive mechanism 321 performs tensioning and loosening of the first cutter assembly 21 (the sliding member moves away from the first tool holder), and the other performs locking and tightening of the first cutter assembly 21 (the sliding member moves toward the first tool holder). The two cooperate with each other to complete the adjustment of the cutting depth of the first cutter 211, thereby avoiding the situation where the first cutter 211 is loose due to tensioning or inadequate adjustment when adjusting. The first slide 3110 and the second slide 3110 use a slide with the same pitch, so that the same displacement can be ensured at the same speed during adjustment.

[0040] like Figure 2As shown, when the cutting depth of the first cutter assembly 21 needs to be increased, the first end of the first knife holder 210 rotates counterclockwise, so the first drive mechanism 311 tensions and releases the first cutter assembly 21, and the second drive mechanism 321 locks and tightens the first cutter assembly 21. When the first end 2101 of the first knife holder 210 rotates clockwise, the second end 2102 of the first knife holder 210 rotates clockwise, and the first cutter is pressed down, thereby increasing the cutting depth of the first cutter 210. On the contrary, the cutting depth of the first cutter assembly 21 can be reduced.

[0041] like Figure 5 As shown, since the first cutter assembly 21 has a certain length, the first adjustment mechanism 31 includes a first adjustment mechanism 31 along the length direction of the cutter (see Figure 5 The first drive mechanism 311 of the first adjustment mechanism 31 of the first group shares the main shaft 3111-a of the first drive mechanism 311 of the first adjustment mechanism 31 of the second group, and thus can share the first drive member 3112. The second drive mechanism 312 of the first adjustment mechanism 31b of the first group shares the main shaft 3211-a of the second drive mechanism 312 of the first adjustment mechanism 31b of the second group, and thus can share the second drive member 3212. The two groups of first adjustment mechanisms 31 are respectively arranged at the axial ends of the first main shaft 3111-a and the axial ends of the second main shaft 3211-a.

[0042] like Figure 1 , Figure 4-6 As shown, the structure and working principle of the second adjustment mechanism 32 are similar to those of the first adjustment mechanism 31, and the main difference lies in the movement direction: the second cutter 220 is pressed upward to increase the cutting depth, and is lowered to reduce the cutting depth. The specific structure and working principle are not described here, and reference may be made to the first adjustment mechanism 31.

[0043] like Figure 1 As shown, if the cutting depth of the cutter device 100 needs to be adjusted, it can be achieved in three ways: the first is to adjust the first cutter assembly 21; the second is to adjust the second cutter assembly 22; the third is to adjust the first cutter assembly 21 and the second cutter assembly 22 at the same time.

[0044] When the first case is adopted, for example, the first cutter 211 of the first cutter assembly 21 is adjusted downward, and the motor on the left side of the first adjustment mechanism 31 needs to rotate counterclockwise, and the motor on the right side needs to rotate clockwise, and the two motors rotate at the same position and speed. Similarly, when the first cutter 211 of the first cutter assembly 21 needs to be adjusted upward, the motor on the left side of the first adjustment mechanism 31 needs to rotate clockwise, and the motor on the right side needs to rotate counterclockwise, and the two motors rotate at the same position and speed. The same control method is used to adjust the cutter of the second cutter assembly 22, and the corresponding motors are adjusted to run at the same position while ensuring the same speed. The second case is similar to the first case, mainly in that the adjustment direction is opposite, which will not be repeated here.

[0045] The cutter device 100 of the embodiment of the present application can achieve precise adjustment of the cutter, which has a positive effect on the normal production cutting of the plate. Compared with the current manual cutter adjustment method, it has higher accuracy and lower failure rate during adjustment. The tooth adjustment position is directly input through the modified upper computer, which is more convenient and quicker for personnel who are not familiar with the cutter adjustment mechanism.

[0046] It will be appreciated by those skilled in the art that all or some of the steps, systems, and functional modules / units in the methods disclosed above may be implemented as software, firmware, hardware, and appropriate combinations thereof. In hardware implementations, the division between the functional modules / units mentioned in the above description does not necessarily correspond to the division of physical components; for example, a physical component may have multiple functions, or a function or step may be performed by several physical components in cooperation. Some or all components may be implemented as software executed by a processor, such as a digital signal processor or a microprocessor, or implemented as hardware, or implemented as an integrated circuit, such as an application-specific integrated circuit. Such software may be distributed on a computer-readable medium, which may include a computer storage medium (or non-transitory medium) and a communication medium (or temporary medium). As known to those skilled in the art, the term computer storage medium includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information (such as computer-readable instructions, data structures, program modules, or other data). Computer storage media include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tapes, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and can be accessed by a computer. In addition, it is well known to those of ordinary skill in the art that communication media typically contain computer-readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism, and may include any information delivery media.
