Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a woodworking cold press that facilitates the alignment of the sides of boards. Background Technology

[0002] There are two types of gluing processes for plywood: hot pressing and cold pressing. The plywood produced by different gluing processes also has certain differences. The advantages of cold pressing are that the finished product has less internal stress, less deformation, and less wood compression loss. The disadvantages are that the production cycle is longer. When cold pressing, the plasticity of the wood and the fluidity of the adhesive are poor, requiring a slightly higher unit pressure. When using urea-formaldehyde resin for cold pressing, the unit pressure is 1.2 MPa, and the gluing time is 6 to 8 hours. The boards are cold pressed in piles, and a pad is placed at certain intervals to ensure that the boards are evenly stressed and that the surface of the board is flat.

[0003] However, existing cold presses generally require manual placement and alignment of the boards before cold pressing. This method results in inconsistent horizontal alignment between the board sides and the mold sides, causing the mold to press against the board sidewalls during descent, leading to a decrease in cold pressing quality. Therefore, those skilled in the art have proposed a woodworking cold press that facilitates board side alignment to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a woodworking cold press that facilitates the alignment of board sides. This woodworking cold press uses a lead screw motor to drive the connecting lead screw to rotate, causing the lead screw slider to slide within the lead screw groove. This, in turn, drives the connecting frame to move within the movable groove, allowing the side baffle to move horizontally and be aligned according to the required alignment position of the board.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A woodworking cold press for facilitating side alignment of boards includes a cold press housing. Screw grooves are formed on the bottom of one side wall of the cold press housing at both the front and rear sides. Screw motors are bolted to one side wall of the cold press housing, located on the side wall of each of the two screw grooves. Movable grooves are formed on the lower side wall of the cold press housing, directly above each of the two screw grooves. The movable ends of the two screw motors penetrate one side wall of the cold press housing and are connected to connecting screws via couplings. The other ends of the two connecting screws are connected to the other side wall of the screw grooves via bearings. Screw sliders are threaded to the outer sides of the two connecting screws. Connecting frames are bolted to the upper side walls of the two screw sliders. The two connecting frames are respectively disposed on the outside of the cold press housing via two movable grooves. Side baffles are bolted to the other ends of the two connecting frames.

[0007] The above technical solution uses a lead screw motor to drive the connecting lead screw to rotate, causing the lead screw slider to slide in the lead screw groove, thereby driving the connecting frame to move in the movable groove. This allows the side baffle to move horizontally, enabling it to be aligned according to the required alignment position of the sheet material. Furthermore, this device is not installed on the processing table of the cold press, so it will not affect the processing of the sheet material.

[0008] Furthermore, a pusher cylinder is bolted to the middle position of the bottom of the other side wall of the cold press housing, and the movable end of the pusher cylinder passes through the other side wall of the cold press housing and is connected to a pusher plate.

[0009] The above technical solution uses a pusher plate to push the sheet material closer to the cold pressing mold.

[0010] Furthermore, a mounting bracket is bolted to the other side wall of the cold press housing, directly below the pusher cylinder, and the other end of the mounting bracket is bolted to both sides of the pusher cylinder.

[0011] The above technical solution secures the pusher cylinder with a mounting bracket, preventing it from becoming loose.

[0012] Furthermore, hydraulic cylinders are bolted to the upper sidewall of the cold press housing at both the front and rear ends. The movable ends of the two hydraulic cylinders penetrate the upper sidewall of the cold press housing and are connected to connecting rods. The bottom of the two connecting rods is connected to a cold press mold.

[0013] The above technical solution uses a hydraulic cylinder to lift and lower the cold pressing mold, while a connecting rod connects the cold pressing mold and the hydraulic cylinder.

[0014] Furthermore, a sliding groove is provided in the middle of both the front and rear side walls of the cold press housing;

[0015] The above technical solution uses a sliding groove to limit the position of the cold pressing mold.

[0016] Furthermore, connecting blocks are fixedly connected to the front and rear side walls of the cold pressing mold, and several pulleys arranged in a linear array are installed on the side walls of the two connecting blocks.

[0017] The above technical solution utilizes pulleys to allow the connecting block to slide within the groove.

[0018] Furthermore, several of the pulleys contact the adjacent sidewall of the slide groove;

[0019] With the above technical solution, the connecting block rolls on the side wall of the slide when passing through the pulley, making the cold pressing mold more stable and less prone to shaking when lifting and lowering.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the connecting screw is driven to rotate by the screw motor, so that the screw slider slides in the screw groove, thereby driving the connecting frame to move in the movable groove, so that the side baffle can move in the horizontal direction and be aligned according to the required alignment position of the plate. Moreover, the device is not installed on the processing table of the cold press, so it will not affect the processing of the plate.

[0022] 2. In this utility model, the connecting block rolls on the side wall of the slide groove by means of pulleys, which makes the cold pressing mold more stable and less prone to shaking when it is raised and lowered, and makes the raising and lowering process of the mold more stable.

[0023] 3. In this utility model, the sheet material is pushed towards the cold pressing mold by the pusher plate, eliminating the need for manual pushing of the sheet material. This is more convenient and avoids the risks associated with manual operation. The pusher cylinder is stabilized by the mounting bracket to prevent it from becoming loose.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-5 This utility model provides an embodiment of a woodworking cold press that facilitates the alignment of board edges. It includes a cold press housing 1. Screw grooves 10 are formed on the bottom of one side wall of the cold press housing 1, near the front and rear sides. Screw motors 12 are bolted to one side wall of the cold press housing 1, located at the side wall of each of the two screw grooves 10. Movable grooves 15 are formed on the lower side wall of the cold press housing 1, directly above each of the two screw grooves 10. The movable ends of the two screw motors 12 penetrate one side wall of the cold press housing 1 and are connected to connecting screws 14 via couplings. The other ends of the two connecting screws 14 are connected to the other side wall of the screw grooves 10 via bearings. Two connecting screws 14 are threaded to the outer walls of their outer sides with screw sliders 13. The upper walls of the two screw sliders 13 are bolted to connecting frames 11. The two connecting frames 11 are respectively set on the outer side of the cold press housing 1 through two movable slots 15. The other ends of the two connecting frames 11 are bolted to side baffles 4. The connecting screws 14 are rotated by the screw motor 12, causing the screw sliders 13 to slide in the screw slots 10, thereby driving the connecting frames 11 to move in the movable slots 15. This allows the side baffles 4 to move horizontally, so that they can be aligned according to the required alignment position of the sheet metal. This device is not installed on the processing table of the cold press, so it will not affect the processing of the sheet metal.

[0033] A pusher cylinder 8 is bolted to the middle of the bottom of the other side wall of the cold press housing 1. The movable end of the pusher cylinder 8 passes through the other side wall of the cold press housing 1 and is connected to a pusher plate 9. The pusher plate 9 pushes the plate closer to the cold press mold 3. A mounting bracket 7 is bolted to the other side wall of the cold press housing 1 and directly below the pusher cylinder 8. The other end of the mounting bracket 7 is bolted to both sides of the pusher cylinder 8. The mounting bracket 7 stabilizes the pusher cylinder 8 and prevents it from becoming loose.

[0034] Hydraulic cylinders 2 are bolted to the upper sidewall of the cold press housing 1 at both the front and rear ends. The movable ends of the two hydraulic cylinders 2 pass through the upper sidewall of the cold press housing 1 and are connected to connecting rods 6. The bottom of the two connecting rods 6 is connected to the cold press mold 3. The cold press mold 3 is raised and lowered by the hydraulic cylinders 2. The connecting rods 6 are used to connect the cold press mold 3 and the hydraulic cylinders 2. Slide grooves 5 are opened in the middle of the front and rear sidewalls of the cold press housing 1. The cold press mold 3 is limited by the slide grooves 5. Connecting blocks 16 are fixedly connected to the front and rear sidewalls of the cold press mold 3. Several pulleys 17 are installed on the sidewalls of the two connecting blocks 16 in a linear array. When using the pulleys 17, the connecting blocks 16 can slide in the slide grooves 5. Several pulleys 17 contact the sidewalls of the adjacent slide grooves 5. When using the pulleys 17, the connecting blocks 16 roll on the sidewalls of the slide grooves 5, making the cold press mold 3 more stable and less prone to shaking when it is raised and lowered.

[0035] Working principle: The pusher plate 9 pushes the sheet material closer to the cold press mold 3, eliminating the need for manual pushing and making it more convenient while avoiding the risks associated with manual operation. The mounting bracket 7 stabilizes the pusher cylinder 8 to prevent it from becoming loose. The lead screw motor 12 drives the connecting lead screw 14 to rotate, causing the lead screw slider 13 to slide within the lead screw groove 10. This, in turn, moves the connecting bracket 11 within the movable groove 15, allowing the side baffle 4 to move horizontally and align according to the required position of the sheet material. Since this device is not installed on the processing table of the cold press, it will not affect the processing of the sheet material. The pusher plate 9 and the side baffle 4 work together to easily align the side edges of the sheet material. The connecting block 16 rolls on the side wall of the slide groove 5 via the pulley 17, making the cold press mold 3 more stable and less prone to shaking during lifting and lowering, thus making the lifting and lowering process of the mold more stable.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
