Description

Technical Field

[0001] The utility model belongs to the technical field of picture frame processing equipment and relates to a nail gun device of a picture frame stretching machine. Background Art

[0002] Picture frames are important tools in the art field. During their production process, the edges of four wooden strips are first stapled into a wooden frame using a stapling machine, and then the cut-to-shape cloth board is stretched on the wooden frame and stapled tightly with staples. Currently, there are also some equipment for stretching picture frames on the market. However, during the stretching process, these devices cannot smoothly fold the edges of the cloth board folded into a vertical state inward, so it is difficult to eliminate wrinkles after the stretching is completed. Moreover, the spacing between adjacent stapling stations cannot be adjusted, the staple gun cannot be used for materials of different specifications and sizes, and the depth of the nails cannot be adjusted.

[0003] The inventor proposed a cloth clamping and tightening device for a CNC canvas frame stretching machine on June 30, 2020 (patent number CN202021259006.8). After several years of research and development and improvements, the inventor found that there were many elements in the original application document that needed to be improved, mainly reflected in the following points: First, the first clamping block and the second clamping block are prone to slipping on the cloth plate, resulting in wrinkles in the stretched cloth; secondly, the nail mouth of the nail gun is too far away from the clamping mouth, resulting in more cloth being consumed at the edge for the nail gun to be able to nail it, which indirectly wastes the cloth cost. Utility Model Content

[0004] The utility model aims to solve the problem of cloth slippage in existing step-frame cloth stretching machines and proposes a nail gun device for a picture frame cloth stretching machine.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] A nail gun device for a picture frame stretching machine is characterized in that it includes a fixed pallet that is fixedly arranged and a sliding pallet that is slidably arranged relative to the fixed pallet. The movement of the sliding pallet and the fixed pallet is realized by a bracket-driven cylinder. A plurality of placement blocks are arranged in parallel on the sliding pallet, and each placement block is provided with a nail gun. The bottom of the fixed pallet has a first clamping body, and the bottom of the sliding pallet has a second clamping body. A clamping opening for clamping fabric is formed between the first clamping body and the second clamping body. The ends of the first clamping body and the second clamping body are both folded line-shaped clamping mouths, so that the first clamping body and the second clamping body form crocodile clamping mouths.

[0007] In the above-mentioned nail gun device of a picture frame stretching machine, a concave opening is provided at the bottom of the placement block, the inner end surface of the concave opening is closer to the fixed support plate than the side surface of the placement block, and the bottom of the nail gun is embedded in the concave opening.

[0008] In the above-mentioned nail gun device of a picture frame stretching machine, a plurality of sliding rods are fixedly provided on the fixed support plate, a plurality of sliding sleeves corresponding to the positions of the sliding rods are fixedly provided on the sliding support plate, sliding holes are penetrated through the sliding sleeves, and the sliding sleeves are slidably sleeved on the sliding rods to form a sliding connection between the sliding support plate and the fixed support plate.

[0009] In the nail gun device of the above-mentioned picture frame stretcher, the placement block is slidably connected to the fixed support plate in the height direction, and the placement block is adjusted in height relative to the fixed support plate through a threaded screw.

[0010] Compared with the prior art, the fabric clamped by the nail gun device is less likely to slip, and the nail mouth of the nail gun is brought closer to the clamping mouth through reasonable design, thereby saving fabric in disguise. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 and Figure 2 As shown, the nail gun device of the picture frame stretching machine includes a fixed pallet 1 and a sliding pallet 2 slidably arranged relative to the fixed pallet. The movement of the sliding pallet 2 and the fixed pallet 1 is realized by a bracket-driven cylinder 3. A plurality of placement blocks 4 are arranged in parallel on the sliding pallet 2. Each placement block 4 is provided with a nail gun 5. The bottom of the fixed pallet 1 has a first clamp 6, and the bottom of the sliding pallet 2 has a second clamp 7. A clamp 8 for clamping the cloth is formed between the first clamp 6 and the second clamp 7. The ends of the first clamp 6 and the second clamp 7 are both folded line-shaped clamp mouths 9, so that the first clamp 6 and the second clamp 7 form a crocodile clamp mouth.

[0016] Compared with the patent document previously applied for by the inventor, this technical solution has an important improvement in that the bottom of the first clamp 6 and the second clamp 7 are no longer ordinary clamp mouths that are easy to slip, but have crocodile clamp mouths similar to pliers and crocodile clamps. In this way, the clamped fabric is difficult to slip out of the clamp mouth 8 during the pulling process, and the tightening function can be achieved without wrinkles.

[0017] A concave opening 10 is provided at the bottom of the placement block 4 , the inner end surface of the concave opening 10 is closer to the fixed support plate 1 than the side surface of the placement block 4 , and the bottom of the nail gun 5 is embedded in the concave opening 10 .

[0018] It can be seen from the drawings of the inventor's previous prior art patent documents that the distance between the nail mouth of the nail gun 5 and the clamping mouth 8 is very far, which requires reserving a long portion of cloth, otherwise the nail gun 5 cannot nail the cloth. In fact, the picture frame only needs the cloth clamped at the edge to be nailed to the wooden strips, and there is no need to reserve so much cloth, so this will greatly lead to the waste of cloth on the edge. Therefore, the present design improves the bottom of the placement block 4 by digging a groove to form a concave mouth 10, and then embeds the bottom of the nail gun 5 in the concave mouth 10, so that the nail gun 5 will be closer to the clamping mouth 8 than the prior art, so that the cloth can be nailed to the picture frame at a position closer to the edge of the picture frame, which saves cloth in disguise.

[0019] A plurality of slide rods 11 are fixed on the fixed support plate 1, and a plurality of slide sleeves 12 corresponding to the positions of the slide rods 11 are fixed on the sliding support plate 2. The slide sleeves 12 are penetrated to form slide holes. The slide sleeves 12 are slidably mounted on the slide rods 11 to form a sliding connection between the sliding support plate 2 and the fixed support plate 1.

[0020] The placement block 4 is slidably connected to the fixed support plate 1 in the height direction, and the placement block 4 is adjusted in height relative to the fixed support plate 1 through a threaded screw.

[0021] It should be understood that in the claims and description of the present utility model, all "including..." should be understood as open-ended, that is, its meaning is equivalent to "at least containing...", and should not be understood as closed-ended, that is, its meaning should not be understood as "only including...".

[0022] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
