Description

Technical Field

[0001] This utility model relates to the field of planing devices, specifically to a planing device for wood products. Background Technology

[0002] When mass-producing wood products in a factory, a wood belt sander is needed to facilitate surface sanding and polishing. The wood belt sander mainly consists of a polishing assembly, a pressing assembly, a support frame, a mounting base, and a fixing plate. Both the support frame and the mounting base have lugs welded to both sides, with threaded holes in the center of each lug. When the fixing base is placed on top of the support frame, the lugs and threaded holes on both sides are aligned, and bolts are used to secure them together. The polishing assembly mainly consists of a roller, sanding belt, pulleys, and a drive motor. During installation, the sanding belt is fitted onto the outer wall of the roller, with the roller positioned at both ends of the sanding belt. Drive shafts are symmetrically installed at the center of both ends of the roller. A bearing seat is installed in the center of one end of the fixing plate. The fixing plate is then attached to both ends of the roller, ensuring the roller... The drive shaft at the center of the end passes through the bearing housing. The end of the fixing plate furthest from the bearing housing is then attached to the two sides of the fixing base. A pulley is bolted to one end of the drive shaft, and the pulley is connected to the output end of the drive motor via a belt (the drive motor is mounted inside a fixed frame, which is bolted to the front of the bracket). This facilitates the rotation of the drive roller, which in turn drives the sanding belt to rotate reciprocally. When the wood board is placed on the sanding belt surface, the top of the board is pressed down by the roller (one end of the roller is connected to the output shaft of the rotary motor, allowing the roller to be driven to rotate; a cylinder can also adjust the roller's height). The reciprocating sanding belt polishes the lower surface of the wood board (see the attached diagram in the instruction manual). Figure 5 (This is a diagram of an existing product assembly).

[0003] However, when sanding boards of different sizes, different widths of sanding belts and different lengths of rollers are required. When sanding a large flat area of ​​a wide board, a wide sanding belt is needed, and the rollers connected to both ends of the sanding belt must also be changed to a length suitable for the wide sanding belt to improve coverage efficiency and avoid the sanding belt being too narrow to fully cover the board surface, resulting in an uneven planed surface. When sanding and planing the curved surfaces and corners of wooden sticks, strips, or some boards, a narrower sanding belt is needed to avoid occupying too much area and to better control the sanding area, avoiding over-sanding. When installing or changing sanding belts of different widths, rollers of corresponding lengths must also be changed, otherwise the sanding belt may slip or break. In the existing technology, the dimensions of the bracket and the fixed base are fixed, and it is impossible to adjust the spacing to accommodate rollers of different lengths. This means that the entire belt sander can only install one type of roller and sanding belt, resulting in poor overall adjustability.

[0004] Therefore, it is necessary to invent a planing device for wood products. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wood product surface planing device, comprising a polishing component, a bracket, a fixing seat, and a fixing plate. The fixing seat is installed on the upper end of the bracket, the fixing plate is symmetrically installed at both ends of the fixing seat, the polishing component is installed between the fixing seat and the fixing plate, a support is fixedly installed at the lower end of the fixing seat, a reinforcing component is installed in the middle of the bracket, and a limiting component is installed on one side of the upper end of the reinforcing component.

[0007] Based on the above features: when it is necessary to change rollers of different lengths and sanding belts of different widths, the limiting component can be pulled open, and then the fixing seat can be pulled in opposite directions. At this time, the bracket and the fixing plate will also move synchronously, which makes it convenient to adjust the distance between the bracket and the fixing seat. It is convenient to install rollers of different lengths and sanding belts of different widths between the fixing seat and the fixing plate. The lower end of the fixing seat is supported on the upper end of the reinforcing component by the support, which increases the force-bearing area. After the distance of all parts is adjusted, the limiting component can be inserted into the inside of the reinforcing component to fix it, preventing the bracket and the fixing seat from shifting on their own, and making it convenient to quickly disassemble and adjust.

[0008] Preferably, the fixing seat has a U-shaped structure.

[0009] Based on the above features: the sanding belt is conveniently located inside the U-shaped fixing seat, and both the fixing seat and the bracket are divided into two parts from the middle, which facilitates pulling and adjusting the spacing in opposite directions.

[0010] Preferably, the reinforcement component includes a first connecting plate and a second connecting plate, wherein a plug plate is fixedly installed on the side of the first connecting plate near the second connecting plate, and the plug plate has interlocking holes spaced apart on its surface.

[0011] Based on the above features: the first connecting plate is movably connected to the second connecting plate through the insert plate; the ends of the first and second connecting plates that are far apart from each other are fixedly connected to the inner wall of the bracket; and the ends of the first and second connecting plates that are close to each other are detachable, so that the first and second connecting plates can be moved synchronously according to the bracket and the fixed seat.

[0012] Preferably, the second connecting plate has a slot in the middle and a through hole at the upper end of the side of the second connecting plate near the first connecting plate.

[0013] Based on the above features: the first connecting plate is inserted into the inside of the slot through the insert plate, and the limiting component can be inserted into the socket from top to bottom through the through hole to connect and fix the insert plate.

[0014] Preferably, the limiting component includes a positioning plate and a movable hole in the middle of the upper end of the positioning plate, through which a pull rod is movably inserted.

[0015] Based on the above features: the pull rod can be raised and lowered in the middle of the positioning plate through the movable hole, which facilitates the limiting and fixing of the insertion plate.

[0016] Preferably, a baffle is fixedly installed at the lower end of the pull rod, a buffer spring is installed at the upper end of the baffle, the buffer spring is sleeved on the outside of the pull rod, and a limit rod is fixedly installed at the lower end of the baffle.

[0017] Based on the above features: when the pull rod is pulled upward, the baffle will simultaneously drive the limit rod to lift and disengage from the insertion hole, facilitating the displacement of the insertion plate. When the pull rod is released, the buffer spring will push the return baffle and the limit rod downward, allowing the limit rod to be inserted into the insertion hole through the through hole to fix the insertion plate, preventing the insertion plate from shifting on its own. This facilitates quick disassembly and assembly of the first connecting plate and the second connecting plate, adjusting the distance between the bracket and the fixing seat, thereby allowing for the fixing of both sides of rollers of different lengths.

[0018] Preferably, the baffle and the buffer spring are located in the middle of the positioning plate, and the diameter of the baffle and the buffer spring is larger than that of the through hole and the movable hole.

[0019] Based on the above features: to prevent the pull rod or limit rod from separating from the positioning plate, and to allow the pull rod and limit rod to move vertically.

[0020] The beneficial effects of this utility model are: 1. Both the fixed base and the bracket are divided in half from the middle, which makes it easier for the fixed base and the bracket to move the fixed plate to adjust the spacing. This allows for fixing of rollers of different lengths on both sides. The reinforcement components improve the fixing effect between the fixed base and the bracket. When it is necessary to replace rollers of different lengths and sanding belts of different widths, the fixed base can be pulled in opposite directions. At this time, the bracket and the fixed plate will also move synchronously to widen the spacing, making it easier to install rollers of different lengths. The brackets are connected and fixed together by a first connecting plate and a second connecting plate. The lower end of the fixed base is also supported above the first connecting plate and the second connecting plate by a support, thereby improving the overall support strength. 2. By setting up reinforcement components and limiting components, the fixed seat and bracket can be quickly moved horizontally or fixed in place. When the pull rod is pulled up, the baffle will simultaneously drive the limiting rod to rise and disengage from the insertion hole. At this time, the bracket and fixed seat can be pulled to adjust the distance between them. After the position of the bracket and fixed seat is adjusted, the pull rod is released, allowing the limiting rod to move down through the through hole and insert into the insertion hole to fix the insertion plate, preventing the fixed seat and bracket from shifting on their own.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] See attached document Figure 5 The existing product structure includes a polishing assembly, a bracket 1, a fixed base 2, and a fixed plate 3. The fixed base 2 is installed on the upper end of the bracket 1, and the fixed plate 3 is symmetrically installed at both ends of the fixed base 2. The polishing assembly is installed between the fixed base 2 and the fixed plate 3. The polishing assembly mainly consists of a roller, a sanding belt, a pulley, and a drive motor. During installation, the sanding belt is sleeved on the outer wall of the roller, and the roller is located at both ends of the sanding belt. Drive shafts are symmetrically installed at the center of both ends of the roller. A bearing seat is installed in the middle of one end of the fixed plate 3. The fixed plate 3 is attached to both ends of the roller body, so that the drive shafts at the center of both ends of the roller pass through the bearing seats. Then, the end of the fixed plate 3 away from the bearing seats is fixed to the two sides of the fixed base 2. When the roller is driven to rotate, it can drive the sanding belt to rotate back and forth. When the wood board is placed on the surface of the sanding belt, the reciprocating sanding belt can polish the lower surface of the wood board.

[0025] See attached document Figure 1-4This utility model provides a wood product surface planing device, including a support 1 and a fixed base 2. The fixed base 2 has a U-shaped structure and is installed above the support 1. Both the support 1 and the fixed base 2 are divided into two parts in the middle and can move in opposite directions. Fixed plates 3 are symmetrically installed on both sides of the fixed base 2 (with a roller rotatably connected in the middle of the fixed plate 3) to facilitate the limiting and fixing of the roller. A support 4 is fixedly installed at the lower end of the fixed base 2. A reinforcing component 5 is installed in the middle of the bracket 1. The reinforcing component 5 is divided into upper and lower layers. The lower end of the fixed seat 2 is supported by the upper reinforcing component 5 through the support 4 to increase the bearing area. The two layers of reinforcing components 5 have the same structure (the two layers of reinforcing components 5 are symmetrically arranged with inclined reinforcing ribs to improve the reinforcement effect). The reinforcing component 5 includes a first connecting plate 51 and a second connecting plate 52. The ends of the first connecting plate 51 and the second connecting plate 52 that are far apart from each other are fixedly connected to the inner wall of the bracket 1. The ends of the first connecting plate 51 and the second connecting plate 52 that are close to each other are detachable. When it is necessary to replace the sanding belt with a wider one, the roller can be removed from the middle of the fixed plate 3. Then, the bracket 1 and the fixed seat 2 can be pulled to move one side (the side of the bracket 1 and the fixed seat 2 that is far away from the drive motor can remain still or move in opposite directions) to increase the distance between the bracket 1 and the fixed seat 2. At this time, a longer roller can be replaced and connected to the middle of the fixed plate 3 to facilitate the adjustment of the distance between the bracket 1 and the fixed seat 2 according to the length of the roller and the width of the sanding belt. The second connecting plate 52 has a slot 521 in the middle and a through hole 522 on the upper side of the second connecting plate 52 near the first connecting plate 51. A plug plate 53 is fixedly installed at one end of the first connecting plate 51. The diameter of the plug plate 53 matches the slot 521, so that the plug plate 53 can be inserted into the inside of the slot 521. The surface of the plug plate 53 has holes 54 spaced apart. The diameter of the holes 54 is the same as that of the through hole 522. The distance between adjacent holes 54 is 2cm. When the distance between the bracket 1 and the fixed base 2 is increased or decreased, the plug plate 53 will also be pulled out and inserted into the inside of the slot 521 accordingly, so as to prevent the first connecting plate 51 and the second connecting plate 52 from separating after being pulled apart.

[0026] See attached document Figure 3-4A limiting component 6 is installed on the upper end of the second connecting plate 52 near the first connecting plate 51. The limiting component 6 includes a positioning plate 61, which is fixed to the upper end of the second connecting plate 52. A movable hole 62 is opened in the middle of the upper end of the positioning plate 61. The diameter of the movable hole 62 is the same as that of the through hole 522 and the insertion hole 54. A pull rod 63 is movably passed through the movable hole 62. A baffle 631 is fixedly installed at the lower end of the pull rod 63. A buffer spring 632 is fixedly installed at the upper end of the baffle 631. The buffer spring 632 is sleeved on the outside of the pull rod 63. The diameter of the baffle 631 and the buffer spring 632 is larger than that of the movable hole 62 and the through hole 522. The baffle 631 and the buffer spring 632 are located in the middle of the positioning plate 61. A limiting rod 633 is fixedly installed at the lower end of the baffle 631. The diameter of the limiting rod 633 matches that of the through hole 522 and the insertion hole 54. When the pull rod 63 is pulled upward, the baffle 631 will simultaneously drive the limiting rod 633 to rise and disengage from the insertion hole 54. At this time, the buffer spring 632 will be squeezed and deformed because it cannot pass through the through hole 522. When one side of the bracket 1 and the fixed seat 2 is pulled to the position of the widening gap, the insertion plate 53 can be pulled out or inserted into the slot 521 for adjustment. After the position of the bracket 1 and the fixed seat 2 is adjusted, ensure that one of the insertion holes 54 on the surface of the insertion plate 53 is aligned with the through hole 522. Finally, release the pull rod 63. At this time, the buffer spring 632 will push the rebound baffle 631 and the limiting rod 633 downward, so that the limiting rod 633 can be inserted into the insertion hole 54 through the through hole 522 to fix the insertion plate 53, preventing the insertion plate 53 from shifting on its own. This facilitates quick disassembly and assembly of the first connecting plate 51 and the second connecting plate 52 to adjust the gap between the bracket 1 and the fixed seat 2, thereby fixing the two sides of rollers of different lengths.

[0027] The usage process of this utility model is as follows: When it is necessary to replace a wider sanding belt, the roller smaller than the width of the sanding belt can be removed from the middle of the fixed plate 3. Then, the pull rod 63 can be pulled up to lift the limiting rod 633 out of the insertion hole 54. Next, the support 1 and the fixed seat 2 are moved to increase the distance between the support 1 and the fixed seat 2. Then, the long roller matching the wide sanding belt is connected in the middle of the fixed plate 3 (the wide sanding belt will cover the outside of the long roller). When the distance between the support 1 and the fixed seat 2 is increased or decreased, the insertion plate 53 will also be pulled out and inserted into the inner side of the slot 521 accordingly, so that the first connecting plate 51 and the second connecting plate 52 will not separate. After the positions of the support 1 and the fixed seat 2 are adjusted, ensure that one of the insertion holes 54 on the surface of the insertion plate 53 is aligned with the through hole 522. Finally, the pull rod 63 is released so that the limiting rod 633 is inserted into the insertion hole 54 through the through hole 522 to fix the insertion plate 53, and the support 1 and the fixed seat 2 will not move on their own.
