Description

Technical Field

[0001] The utility model relates to the technical field of plate cutting, in particular to a clamping mechanism and a plate cutting machine with the mechanism. Background Art

[0002] A board cutting machine is a device for cutting wood and is commonly used in some home furnishing manufacturing companies.

[0003] In order to ensure cutting stability, current cutting machines generally fix the wood on the cutting table of the cutting machine through the clamping mechanism of the cutting machine. However, a large amount of wood chips will be generated during the cutting process. Therefore, when the wood is loaded or clamped, these wood chips will exist between the wood and the cutting table or between the wood and the clamping mechanism. Therefore, when the wood is moved, there is a defect that the wood is scratched, which affects the production quality of the company's products. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a clamping mechanism and a plate cutting machine having the mechanism, aiming to solve the problems arising from the above-mentioned background technology.

[0005] The technical solution of the utility model is implemented as follows: a plate cutting machine, comprising a cutting table supported by a frame, a cutting device for cutting the plate and a clamping mechanism of the utility model, wherein the clamping mechanism of the utility model can be installed on the cutting table; wherein the clamping mechanism comprises:

[0006] A clamping frame, comprising a first bracket and a second bracket arranged longitudinally;

[0007] The cylinder is arranged on the first bracket or the second bracket and can control the first bracket and the second bracket to move closer to or farther from each other;

[0008] A conveying roller is rotatably disposed on the first bracket and the second bracket;

[0009] Wherein, a dust collecting body is formed on the first bracket and / or the second bracket, and a dust collecting port is formed on a side of the dust collecting body close to the conveying roller.

[0010] By adopting the above technical solution:

[0011] The utility model is provided with a conveying roller on the clamping mechanism, and the conveying roller can assist in the loading and unloading of wood. Compared with the loading method in the prior art (i.e., pushing the wood onto the cutting table), the utility model can reduce the wear on the wood by assisting the wood loading with the conveying roller, and uses the cylinder to control the distance between the first bracket and the second bracket, and can also use the conveying roller to clamp and fix the wood, thereby ensuring the stability of wood cutting.

[0012] Preferably, the dust collecting body comprises:

[0013] An outer body is mounted on the first bracket or the second bracket and is located between the conveying rollers;

[0014] Telescopic cavities are formed at both ends of the outer body and correspond to each conveying roller;

[0015] The inner body is arranged in each telescopic cavity, connected to the cavity bottom of the telescopic cavity through a limit spring, and has a dust suction cavity;

[0016] A dust extraction pump is connected to the dust suction chamber through a dust extraction pipe;

[0017] The electromagnet is disposed in the outer body and between the telescopic cavities;

[0018] The inner body is opened at one end close to the conveying roller, and the contact surfaces of the outer body and the inner body are provided with a first dust suction hole and a second dust suction hole which can be displaced or connected to each other.

[0019] Preferably, the open end of the inner body is rolled outward to form a folded edge, so that the input end of the dust suction chamber forms a trumpet-shaped dust suction port;

[0020] When the electromagnet is energized and produces magnetism, the inner body is attracted to move into the telescopic cavity, and the folded edge contacts the cavity opening of the telescopic cavity;

[0021] When the electromagnet is powered off and loses its magnetism, the inner body is controlled by the limit spring to move out of the telescopic cavity and abut against the conveying roller.

[0022] Preferably, the diameter of the first dust suction hole gradually decreases from the air intake direction.

[0023] Preferably, the folded edge is wrapped with a rubber layer.

[0024] By adopting the above technical solution:

[0025] In order to further reduce the wear of wood chips on wood, the utility model provides a dust collector on the clamping frame, which can clean the conveying roller in time. At the same time, in order to ensure the stability of clamping, the inner body can be controlled by a limit spring to contact with the conveying roller to fix the conveying roller, thereby improving the stability of fixing the wood.

[0026] In addition, other advantages of the present invention will be demonstrated in the embodiment section of the present invention, thereby making the beneficial effects of the present invention more significant. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example 1

[0034] like Figure 1-2 As shown, the utility model discloses a plate cutting machine, including a cutting table 11 supported by a frame 10, a cutting device for cutting the plate (not shown) and a clamping mechanism of this embodiment, which can be installed on the cutting table 11.

[0035] In this embodiment, since the cutting device is a relatively mature existing technology, it is not described in detail in this embodiment. Nevertheless, this embodiment still extends the mounting table 110 on the front and rear sides of the cutting table 11, and a cutting groove 111 is set on the cutting table 11 and the mounting table 110. Therefore, in order to ensure that the plate on the cutting table can be cut, the cutting device can ensure that the cutting groove can reciprocate (in the Z direction) in the cutting groove during installation, so that the plate can be cut.

[0036] In this embodiment, the important clamping mechanism can assist the loading, unloading and clamping of the plate on the cutting table 11, and the clamping mechanism includes:

[0037] The clamping frame is composed of a first bracket 21 and a second bracket 22 arranged longitudinally;

[0038] The cylinder 23 is disposed on the first bracket 21 and is capable of controlling the first bracket 21 and the second bracket 22 to move closer to or farther from each other;

[0039] The conveying roller 24 is rotatably disposed on the first bracket 21 and the second bracket 22;

[0040] A dust collecting body 25 is formed on the first bracket 21 and / or the second bracket 22 , and a dust collecting port 26 is formed on a side of the dust collecting body 25 close to the conveying roller 24 .

[0041] In this embodiment, to ensure the stable movement of the first bracket 21 and the second bracket 22, a guide column 30 is provided on the first bracket 21, and a guide cavity 31 for the movement of the guide column 30 is provided on the second bracket 22, and the guide cavity 31 is provided to penetrate the second bracket 22 longitudinally.

[0042] refer to Figure 1-2 When this embodiment is in use, the plate is pushed onto the cutting table from one side (x direction) of the cutting table, and guided by the conveying roller, the two sides of the plate are located on the clamping mechanisms on both sides of the cutting table, and the second bracket is controlled to descend and clamp the plate by driving the motor to complete the fixation. After the cutting is completed, the cylinder controls the second bracket to rise and release the plate, and the cut plate can be moved out from both sides of the cutting table.

[0043] In this embodiment, a dust collector is arranged between the conveying rollers of the first bracket and the second bracket. When in use, the dust collector is connected to the dust pump through a dust suction pipe (the first bracket and the second bracket are provided with a dust suction nozzle 32 for connecting the dust suction pipe). Therefore, when the dust suction pump is started, impurities (such as wood chips) on the conveying roller can be sucked away, thereby preventing the wood chips on the conveying roller from scratching the wood during loading.

[0044] Embodiment 2 is different from Embodiment 1 in that

[0045] like Figure 3-4 As shown, in this embodiment: the dust collecting body 25 includes:

[0046] The outer body 40 is mounted on the first bracket 21 or the second bracket 22 (the dust collecting body 25 on the first bracket 21 is taken as an example in this embodiment) and is located between the conveying rollers 24;

[0047] The telescopic chambers 41 are formed at both ends of the outer body 40 and correspond to the conveying rollers 24;

[0048] The inner body 42 (made of metal material) is disposed in each telescopic cavity 41 and connected to the cavity bottom of the telescopic cavity 41 through a limit spring 43, and has a dust suction cavity 420;

[0049] A dust extraction pump (not shown) is connected to the dust suction chamber 420 through a dust extraction pipe;

[0050] The electromagnet 44 is disposed in the outer body 40 and between the telescopic chambers 41;

[0051] The inner body 42 is opened at one end close to the conveying roller 24 , and the contact surfaces of the outer body 40 and the inner body 42 are provided with a first dust suction hole 45 and a second dust suction hole 46 which can be displaced or connected to each other.

[0052] In this embodiment: the open end of the inner body 42 is rolled outward to form a folded edge 42a, so that the input end of the dust suction chamber 420 forms a trumpet-shaped dust suction port;

[0053] When the electromagnet 44 is energized to generate magnetism, the inner body 42 is attracted to move into the telescopic cavity 41, and the folded edge 42a contacts the cavity opening of the telescopic cavity 41;

[0054] When the electromagnet 44 is powered off and loses its magnetism, the inner body 42 is controlled by the limit spring 43 to move out of the telescopic cavity 41 and abut against the conveying roller 24 .

[0055] In this embodiment, the diameter of the first dust suction hole 45 gradually decreases from the air intake direction, so that the shape of the first dust suction hole 45 forms a trumpet shape, thereby improving the dust suction effect.

[0056] In this embodiment: the folded edge 42a is wrapped with a rubber layer 42b to increase the friction when the folded edge contacts the conveying roller 42, and also to increase the sealing effect when the folded edge 42a contacts the opening of the telescopic cavity or the conveying roller.

[0057] refer to Figure 3-4 The principle of this embodiment is that, in order to ensure the stability of the first bracket and the second bracket in clamping the wood, when clamping, the electromagnet is powered off, and the inner body is controlled by the limit spring to contact with the conveying roller and limit the rotation of the conveying roller (providing a "brake" function for the conveying roller). Therefore, when the first bracket and the second bracket clamp the wood through the conveying roller, it can be more stable, thereby ensuring the stability of cutting;

[0058] When the cutting is completed, in order to improve the dust suction effect, the electromagnet can be energized in this embodiment (the inner body is separated from the conveying roller). In this way, when the wood is removed, the conveying roller can be selected normally, and the energization of the electromagnet attracts the inner body to move into the telescopic cavity, and aligns the first dust suction hole and the second dust suction hole. In this way, when the dust pump is started, the conveying roller can be cleaned through the dust suction port at one end of the inner body, and the wood can be cleaned through the first dust suction hole and the second dust suction hole, thereby improving the cleaning effect.

[0059] It is worth mentioning that in this embodiment, when the conveying roller is fixed by the inner body, the first dust suction hole and the second dust suction hole are offset from each other. In this way, when cutting, the dust suction pump is started to use the dust suction port on one side of the inner body to absorb the conveying roller, thereby further fixing the conveying roller and ensuring the stability of clamping.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
