Description

Technical Field

[0001] The invention relates to the technical field of furniture production and processing, and in particular to a trimming device for producing and processing wooden furniture. Background Art

[0002] In the production and processing of wooden furniture, trimming is a crucial process. It not only affects the aesthetics of the furniture, but also directly affects the structural stability and durability of the furniture. The main purpose of trimming is to remove burrs, uneven parts and excess wood materials on the edges of the wood, making the edges of the furniture smoother and neater, thereby improving the overall quality. In addition, trimming can also be used to chamfer the edges of the furniture, which can not only enhance the safety performance of the furniture and prevent sharp edges from causing harm to users, but also give the furniture more rounded and elegant lines to meet the aesthetic needs of modern homes.

[0003] In order to achieve efficient trimming, handheld trimmers have become an indispensable tool in the production and processing of wooden furniture. With its flexible and portable features, handheld trimmers can easily cope with the edge trimming needs of wooden furniture of various complex shapes. It is usually equipped with a high-speed rotating trimming head, which is driven by a motor to perform fine cutting on the edge of the wood at an extremely high speed. The operator only needs to hold the trimmer and push it steadily along the edge of the furniture to complete high-quality trimming.

[0004] However, although handheld trimmers play an important role in the production and processing of wooden furniture, there are still some problems in the prior art that need to be solved. The most critical one is the matching problem between the rotation direction of the trimming head of the trimmer and the pushing direction of the handheld trimmer along the edge of the wooden furniture. Since the working speed of the trimmer is usually fast, this feature requires the operator to ensure that the moving direction is highly consistent with the rotation direction of the trimming head when pushing the trimmer.

[0005] However, in actual operation, especially when used by novice operators, due to lack of experience or careless operation, it is easy to cause the pushing direction of the handheld trimmer to not match the rotation direction of the trimming head of the trimmer. In this case, the trimmer may become stuck, that is, the trimming head encounters too much resistance on the edge of the wood and cannot rotate smoothly, which in turn causes the machine to jam or even shut down. What is more serious is that when the trimmer is subjected to excessive reaction force, it may slip out of the hand, causing the trimmer to pop out out of control, which is not only likely to cause damage to the trimmer itself, but also may pose a serious safety threat to the operator. For example, the popped-out trimmer may injure the operator, or when the high-speed rotating trimming head accidentally touches the operator's fingers, it may twist them into the machine, causing irreversible damage and posing a safety hazard.

The pulley 16 is used to reduce the friction between the bottom backrest 4, the bottom plate 72 and the clamping plate 13 and the side backrest 9, thereby promoting the smooth movement of the trimmer 1.

[0032] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0033] Step 1. When in use, the first screw rod 3 is rotated according to the chamfering depth or trimming depth required for the wooden furniture. The rotational force generated by the rotation of the first screw rod 3 can cause the bottom support 4 to move up and down along the slide rail 2, so that the length of the bottom end of the trimmer 1 extending from the bottom end of the bottom support 4 can be adjusted until it is adjusted to a suitable position. The device is placed in a suitable position to cause the bottom end of the trimmer 1 to align with the edge of the wooden furniture, start the trimmer 1, press the side support 9 with one hand, hold the trimmer 1 with the other hand, and push the trimmer 1 to move to the left along the edge of the wooden furniture. In the process of the trimmer 1 moving to the left, Under the cooperation of the gear 710 and the rack 11, the gear 710 drives the ratchet 74 to rotate through the rotating cylinder 73. The rotation of the ratchet 74 can push the pawl 78 and cause the coil spring 77 to undergo elastic deformation until the trimmer 1 moves to a suitable position. Under the elastic force of the coil spring 77, the pawl 78 can be restored to its initial position. Therefore, under the cooperation of the ratchet 74 and the pawl 78, the gear 710 cannot drive the rotating cylinder 73 to rotate in the opposite direction, and the trimmer 1 cannot move to the right, thereby limiting the pushing and moving direction of the trimmer 1. At this point, the trimmer 1 can be used to chamfer or trim the edges of wooden furniture.

[0034] Step 2: When it is necessary to move the trimmer 1 to the right, turn the knob 76, which can drive the pawl 78 to rotate through the rotating rod 75, and cause the coil spring 77 to elastically deform until the pawl 78 and the ratchet wheel 74 are separated. At this time, the trimmer 1 can be slid to the right. After the trimmer 1 moves to a suitable position, release the knob 76, and the pawl 78 can be restored to its initial position through the rotating rod 75 under the elastic force of the coil spring 77.

[0035] Step 3: When it is necessary to separate the trimmer 1 and the side support 9, rotate the nut 15 until the nut 15 is separated from the outer wall of the second screw rod 12, so as to release the fixation of the pressing plate 14, remove the pressing plate 14 from the outer wall of the second screw rod 12, remove the clamping plate 13 from the outer wall of the guide rod 8, and pull the guide rod 8 out of the inner cavity of the movable groove 10, so as to separate the trimmer 1 and the side support 9;

[0036] Step 4. This device effectively limits the pushing direction of the trimmer through the cooperation mechanism of the ratchet and pawl, ensuring its high consistency with the rotation direction of the trimming cutter head, thereby avoiding safety hazards such as cutter jamming, machine jamming, and slipping of the hands due to improper operation, significantly improving the efficiency and safety of trimming operations, protecting operators from accidental injuries, and also ensuring the smooth progress of the trimmer and furniture processing process.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
