Description

Technical Field

[0001] This invention relates to the field of grinding machine technology, and more specifically to a side grinding machine. Background Technology

[0002] After the wood-plastic composite board is produced, there are rough edges on the sides of the board. The sides need to be sanded with a sander to improve the appearance quality of the board.

[0003] A patent with publication number CN217966398U discloses a side-grinding machine, including a frame with a transport component mounted on it. Material is transported from one end of the frame to the other by the transport component. A grinding component is also mounted to grind the material on the transport component. A clamping component, capable of lifting relative to the transport component, is mounted above it. A profile component, supporting the material, is located below the transport component. The main structural feature of this grinding machine is that the lifting adjustment is achieved through the clamping component, making it suitable for grinding plates of different thicknesses.

[0004] However, current grinding equipment has the following problems: after grinding, the surface of the sanding belt will be covered with debris. Generally, the debris is sucked off the surface of the sanding belt by an air suction device, but the cleaning effect is limited, resulting in the sanding belt debris not being effectively cleaned, which affects the subsequent grinding quality. Therefore, we need to consider how to clean the sanding belt at the same time during continuous grinding. In view of this, we propose a side grinding machine. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings mentioned in the background section and provide a side grinding machine.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A side grinding machine includes a conveying device for conveying a plate, and further includes:

[0008] The drive roller is rotatably mounted on the output side of the conveying device via a shaft, and is used to rotate as the plate moves;

[0009] Two grinding components, including a mounting plate on which a base plate is detachably mounted below, and multiple rollers mounted on the mounting plate by a motor, with a grinding belt sleeved on the multiple rollers, the grinding belt being used to grind the two sides of the plate body;

[0010] The chip removal section is used to remove the debris adhering to the abrasive belt during abrasion. It includes a ratchet mounted on the insert shaft and a mounting block mounted on the base plate and provided with a limiting lifting groove. A pawl corresponding to the ratchet is mounted in the limiting lifting groove.

[0011] A cleaning brush is connected above the pawl via a rod, and the cleaning brush is used to move up and down against the surface of the abrasive belt.

[0012] Preferably, the mounting block is provided with a vertical groove for inserting the ratchet and pawl, and the mounting block is provided with an insertion hole located above the limiting lifting groove;

[0013] The insertion rod is inserted into the insertion hole;

[0014] A base plate is detachably installed below the mounting block.

[0015] Preferably, the pawl has protrusions on both sides for sliding installation in the limiting lifting groove, and the insertion rod is installed on the protrusions;

[0016] A spring is fitted on the insert rod and located between the protrusion and the base plate.

[0017] Preferably, the mounting block is provided with a guide groove for moving the abrasive belt, and a cleaning chamber communicating with the guide groove;

[0018] The cleaning brush is inserted into the cleaning chamber.

[0019] Preferably, the cleaning chamber has a cavity after the cleaning brush is inserted, and a suction pipe is connected to the cavity for connecting an external suction device.

[0020] Preferably, the protrusion has a prism-shaped structure.

[0021] Preferably, the insert shaft is fixedly installed at the center of the transmission roller shaft, and the insert shaft is provided with a protruding structure;

[0022] The ratchet is slidably mounted on the insert shaft.

[0023] Preferably, the conveying device has a lower pressure plate that is lifted and lowered by a lifting cylinder, and multiple pressure rollers are rotatably mounted on the lower pressure plate.

[0024] Preferably, the grinding assembly is provided with a bottom fixing seat below it, and the bottom fixing seat is provided with a moving rail for slidingly mounting the bottom support plate;

[0025] A second electric cylinder for moving the grinding assembly is mounted on the bottom mounting base.

[0026] Preferably, an inner top plate is mounted on the mounting plate via a first electric cylinder, and the inner top plate is disposed inside the grinding belt.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This side grinding machine has a chip removal section between the grinding components and the drive roller. The drive roller is driven to rotate by the plate during the conveying process, which in turn causes the ratchet to rotate. If there is no plate grinding, the chip removal section will not move. This device can convert the forward conveying power of the conveyor into the cleaning power for cleaning the grinding belt, thereby cleaning the debris on the grinding belt. This helps to reduce the amount of residual debris on the belt and thus improves the quality of subsequent side grinding. Attached Figure Description

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1-6 The present invention will describe the above technical solution in detail through the following embodiments:

[0043] A side grinding machine includes a conveying device 2 for conveying a plate 1, a lower pressure plate 3 mounted on the conveying device 2 via a lifting cylinder 5, and a pressure roller 4 rotatably mounted on the lower pressure plate 3. The machine also includes:

[0044] Drive roller 6, such as Figure 1 The structure shown is rotatably mounted on the output side of the conveying device 2 via a shaft 61, and rotates as the plate 1 moves. The shaft 61 is fixedly mounted at the axis of the transmission roller 6, and the shaft 61 is provided with... Figure 2 , Figure 3 The raised structure shown.

[0045] Two grinding components 8 include a mounting plate 81 on which a base plate 84 is detachably mounted. Three rollers 83 are mounted on the mounting plate 81 via a motor 82. Abrasive belts 87 are fitted onto the rollers 83 and are used to grind the sides of the plate body 1. Specifically, as shown... Figure 3 and Figure 4 As shown in the structure, a bottom fixing seat 9 is provided below the grinding assembly 8. The bottom fixing seat 9 is provided with a moving rail 91 for slidingly mounting the bottom support plate 84. A second electric cylinder 10 for moving the grinding assembly 8 is installed on the bottom fixing seat 9. An inner top plate 85 is installed on the mounting plate 81 through a first electric cylinder 86. The inner top plate 85 is located inside the grinding belt 87 to maintain effective contact between the grinding surfaces and avoid the problem of weakening the grinding effect due to deformation of the grinding belt 87.

[0046] The chip removal section 7 is used to remove the debris adhering to the sanding belt 87 during sanding. It includes a ratchet 73 mounted on the insert shaft 61 and a mounting block 71 mounted on the base plate 84 and provided with a limiting lifting groove 716. A pawl 74 corresponding to the ratchet 73 is installed in the limiting lifting groove 716. A cleaning brush 77 is connected above the pawl 74 via an insert rod 76. The cleaning brush 77 is used to move up and down against the surface of the sanding belt 87.

[0047] like Figure 5 , Figure 6As shown in the structure, in this embodiment, the mounting block 71 is provided with a vertical groove 711 for inserting the ratchet 73 and the pawl 74, and the mounting block 71 is provided with an insertion hole 712 located above the limiting lifting groove 716, and the insertion rod 76 is inserted into the insertion hole 712; in this embodiment, a base plate 72 is detachably installed below the mounting block 71, which facilitates the insertion of the pawl 74 into the limiting lifting groove 716 from bottom to top.

[0048] like Figure 6 As shown in the structure, the pawl 74 has protrusions 741 on both sides for sliding installation in the limiting lifting groove 716. The insertion rod 76 is installed on the protrusions 741. In this embodiment, in order to avoid the pawl 74 from rotating and to allow it to move vertically, the protrusions 741 adopt a prism-shaped structure. At the same time, a spring 75 is sleeved on the insertion rod 76 and located between the protrusions 741 and the base plate 72. The spring 75 can be driven by the rotation of the ratchet 73 to push the pawl 74 down and reset it again, thus forming a reciprocating up and down movement.

[0049] In this embodiment, the mounting block 71 is provided with a guide groove 714 for moving the sanding belt 87, and a cleaning chamber 713 communicating with the guide groove 714. The cleaning brush 77 is inserted into the cleaning chamber 713. After the cleaning brush 77 is inserted into the cleaning chamber 713, a cavity is left. The cavity is connected to a suction pipe 715. The suction pipe 715 is used to connect an external suction device to suck out the debris after cleaning. In order to be suitable for sanding operations on boards 1 with different widths, in this embodiment, the ratchet 73 is slidably mounted on the insert shaft 61 and moves synchronously as the sanding distance between the two sanding components 8 is adjusted.

[0050] The working principle of the side sander in this embodiment is as follows: During the conveying process of the plate 1, it passes through the transmission roller 6. The transmission roller 6 rotates, which drives the ratchet 73 to rotate. During the rotation of the ratchet 73, it will squeeze the pawl 74 with the spring 75 installed below. After the pawl 74 is pressed down, the ratchet 73 continues to rotate forward. Then the pawl 74 returns to its original position. This process realizes the up and down movement of the pawl through the movement of the plate 1, which in turn drives the cleaning brush 77 to move up and down. The sanding belt 87 in contact with the cleaning brush is cleaned, and the debris is sucked out by the vacuum cleaner connected to the suction pipe 715.

[0051] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0052] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
