Description

Technical Field

[0001] This utility model relates to the field of plywood technology, and in particular to a trimming machine for plywood production. Background Technology

[0002] In the plywood production process, the plywood needs to be sawed and sanded. Nowadays, sawing and sanding are done in two separate processes. The machine that saws the plywood is called an edge trimming machine. It cuts the four sides of the plywood to make the four sides more even.

[0003] In the prior art, such as the automatic edge-sawing machine for plywood production with announcement number CN214819215U, there is a machine base. An outer plate is vertically fixedly installed on the upper left side of the machine base. A rectangular through-hole is vertically opened on the left side of the machine base. The upper part of the outer plate is movably hinged to the upper part of the baffle plate by a pin. The guard plate set on the machine base in this utility model can improve safety. When the saw wheel needs to be inspected and replaced later, the fixing bolt is first rotated counterclockwise to separate it from the support plate. However, in the prior art, the automatic edge-sawing machine for plywood production cannot squeeze and fix the plywood during the cutting process, which makes the plywood easy to move during the cutting process, resulting in low processing accuracy of the plywood. Therefore, an edge-trimming machine for plywood production is proposed. Utility Model Content

[0004] In view of this, the present utility model aims to provide a trimming machine for plywood production to solve or alleviate the technical problems existing in the prior art. By installing a hydraulic cylinder, the extrusion plate can be pushed to slide, so that the extrusion plate can squeeze and fix the board during the sliding process. When the board is squeezed and fixed, the board is less likely to deviate during the cutting process, thereby making the cutting accuracy of the board higher.

[0005] The technical solution of this utility model embodiment is implemented as follows:

[0006] A plywood trimming machine includes a base assembly. A sliding seat is slidably mounted on the base assembly, and a fixed frame is fixedly mounted on the sliding seat. Two hydraulic cylinders are fixedly mounted on the fixed frame, and an extrusion plate is fixedly mounted on the output end of each of the two hydraulic cylinders. A first motor is fixedly mounted on the base assembly, and two side plates are slidably mounted on it. Two threaded rods, which are threadedly engaged with the two side plates respectively, are fixedly mounted on the output end of the first motor. A second motor is fixedly mounted on each of the two side plates, and a saw blade is fixedly mounted on the output end of each of the two second motors.

[0007] Preferably, the base assembly includes a fixed base and a fixed base plate fixedly mounted on the fixed base. The lower side of the fixed base is provided with four connecting legs, all of which are fixedly connected to the fixed base plate. The connecting legs facilitate the fixed connection between the fixed base plate and the fixed base.

[0008] Preferably, two first guide bars are fixedly installed on the lower surface of the sliding seat. Both first guide bars are inverted T-shaped structures and are slidably engaged with the fixed base. The installation of the first guide bars can guide the sliding seat during the sliding process, thereby making the sliding seat slide more smoothly.

[0009] Preferably, the lower side of the fixed frame is provided with four connecting square columns, each fixedly connected to the sliding seat. The output ends of the two hydraulic cylinders pass through the sliding seat. The upper surfaces of the two extrusion plates are respectively fixedly installed with four guide rods that pass through the fixed frame. The installation of the guide rods can guide the extrusion plates during the sliding process, thereby making the extrusion plates slide more smoothly.

[0010] Preferably, the fixed base plate is located at the bottom of the fixed base. The fixed base plate is a rectangular plate structure. The first motor is fixedly installed on the fixed base plate. Two second guide bars are fixedly installed on the fixed base plate. Both second guide bars are inverted T-shaped structures. The installation of the second guide bars can guide the side plate during the sliding process, thereby making the side plate slide more smoothly.

[0011] Preferably, the two ends of the two second guide bars pass through the two side plates, and each side plate has a threaded hole corresponding to the two threaded rods. The output ends of the two second motors pass through the two side plates respectively, and the two saw blades are located on both sides of the two side plates. The threaded holes facilitate the threaded engagement between the side plates and the threaded rods.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] I. This utility model uses a hydraulic cylinder to push the extrusion plate to slide, thereby squeezing and fixing the sheet material during the sliding process. Once the sheet material is squeezed and fixed, it is less likely to shift during the cutting process, thus resulting in higher cutting precision.

[0014] Second, by installing a first motor, this utility model can push the two side plates closer to each other or further apart. Because the two side plates can move closer to each other or further apart, the saw blades located on the two side plates can cut plates of different widths, thus enabling the trimming machine to cut plates of different widths.

[0015] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1-4As shown, this utility model embodiment provides a plywood trimming machine, including: a base assembly 1, a sliding seat 2 slidably fitted on the base assembly 1, a fixed frame 3 fixedly installed on the sliding seat 2, two hydraulic cylinders 4 fixedly installed on the fixed frame 3, an extrusion plate 5 fixedly installed on the output end of each of the two hydraulic cylinders 4, a first motor 6 fixedly installed on the base assembly 1, two side plates 7 slidably fitted on the base assembly 1, two threaded rods 8 respectively threadedly fitted to the two side plates 7 fixedly installed on the output end of the first motor 6, a second motor 9 fixedly installed on each of the two side plates 7, and a saw blade 10 fixedly installed on the output end of each of the two second motors 9.

[0025] In this embodiment, specifically: the base assembly 1 includes a fixed base 11 and a fixed base plate 12 fixedly installed on the fixed base 11. The lower side of the fixed base 11 is provided with four connecting legs, all of which are fixedly connected to the fixed base plate 12. The installation of the fixed base 11 facilitates the installation of the sliding seat 2.

[0026] In this embodiment, specifically: two first guide bars 13 are fixedly installed on the lower surface of the sliding seat 2. Both first guide bars 13 are inverted T-shaped structures. Both first guide bars 13 are slidably engaged with the fixed base 11. The installation of the sliding seat 2 facilitates the trimming machine to drive the board to slide.

[0027] In this embodiment, specifically: four connecting square columns are provided on the lower side of the fixed frame 3, each fixedly connected to the sliding seat 2; the output ends of the two hydraulic cylinders 4 pass through the sliding seat 2; and four guide rods 14, each passing through the fixed frame 3, are fixedly installed on the upper surface of the two extrusion plates 5. The installation of the guide rods 14 can guide the extrusion plates 5 during the sliding process, thereby making the extrusion plates 5 slide more smoothly.

[0028] In this embodiment, specifically: the fixed base plate 12 is located at the bottom of the fixed base 11. The fixed base plate 12 is a rectangular plate structure. The first motor 6 is fixedly installed on the fixed base plate 12. Two second guide bars 15 are fixedly installed on the fixed base plate 12. Both second guide bars 15 are inverted T-shaped structures. The installation of the first motor 6 facilitates the sliding of the two side plates 7.

[0029] In this embodiment, specifically: the two ends of the two second guide bars 15 pass through the two side plates 7, and the two side plates 7 are provided with threaded holes corresponding to the two threaded rods 8. The output ends of the two second motors 9 pass through the two side plates 7 respectively. The two saw blades 10 are located on both sides of the two side plates 7.

During the sliding process, the extrusion plate 5 presses and fixes the sheet material.

[0031] When the trimming machine needs to trim boards of different widths, the first motor 6 is turned on. The first motor 6 drives the two threaded rods 8 to rotate. The rotation of the threaded rods 8 causes the two side plates 7 to slide closer or further apart. At this time, the distance between the two saw blades 10 changes. Then the second motor 9 is turned on. The second motor 9 drives the two saw blades 10 to rotate. At this time, the saw blades 10 trim the boards during the rotation process.
