Description

Technical Field

[0001] This utility model relates to the field of fabric leveling devices, and in particular to a flat scraping bed adjustment mechanism for a fabric scraping machine. Background Technology

[0002] After fabric production, uneven areas, loose threads, and pilling are inevitable on the surface. These are typically addressed using a scraper to smooth the fabric and achieve a smoother surface. The scraper is usually mounted on a support frame, with a roller below the frame to support and spread the fabric. The fabric is wrapped around the roller, and the scraper is positioned above it. The fabric passes under the scraper. However, after prolonged use, especially when working in conjunction with the roller, wear and tear on the roller or scraper can lead to imbalances, even with adjustments at both ends. Furthermore, if the fabric is too wide, the scraper or roller may be too long, causing the middle section to sag. Existing adjustment devices often struggle to compensate for this error, affecting the fabric's surface finish. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a flat scraping bed adjustment mechanism for a fabric scraping machine.

[0004] This utility model is achieved by the following technical solution: a flat scraper adjustment mechanism for a fabric scraping machine, including an up-and-down adjustment component, the up-and-down adjustment component including a coarse adjustment part and a fine adjustment part, the coarse adjustment part being used to adjust the up-and-down movement of the scraper, and the fine adjustment part being used to tighten the scraper and push the edge of the scraper to abut against it;

[0005] Both the scraper and the coarse adjustment part are mounted on the support frame. The two ends of the scraper are mounted on the support frame. The coarse adjustment part is mounted on the support frame and abuts against the end of the scraper. The fine adjustment part is mounted on the support frame and is evenly distributed along the length of the scraper and abuts against the scraper.

[0006] The coarse adjustment part includes a coarse adjustment sleeve, a coarse adjustment screw, and a rotating wrench. The coarse adjustment sleeve is fixed on the support frame. The coarse adjustment screw is inserted into the coarse adjustment sleeve and passes through the coarse adjustment bar, pressing against the end of the scraper and rotating with the end of the scraper. The coarse adjustment sleeve has a thread inside that mates with the coarse adjustment screw. The rotating wrench is located at the end of the coarse adjustment screw away from the scraper. Pushing the rotating wrench causes the coarse adjustment screw to rotate, which in turn causes the scraper to move up and down.

[0007] The support frame has a limiting waist hole, and the end of the scraper is inserted into the limiting waist hole. The limiting waist hole is arranged along the height direction of the support frame. The top opening of the limiting waist hole is used to pass through the coarse adjustment screw. The rotation of the coarse adjustment screw drives the scraper to move along the limiting waist hole.

[0008] The fine-tuning unit includes fine-tuning cylinders, which are fixed on the support frame and whose extension shafts abut against the scraper. The fine-tuning cylinders are spaced apart on the support frame and evenly distributed along the length of the scraper.

[0009] The scraper includes a back and a blade. The end of the back is mounted on a support frame. A mounting groove is formed on one side of the back. The blade is inserted into the mounting groove. A fixing hole is formed on the side wall of the mounting groove. A corresponding hole is formed on the blade and it is fixed in the mounting groove by bolts.

[0010] Compared to existing technologies, this invention utilizes the cooperation of two sets of adjustment parts to achieve more precise adjustment of the scraper, counteracting the deformation caused by an excessively long scraper. This results in a more precise gap between the scraper and the roller, ensuring that the stretched fabric makes full contact with the roller when passing through this gap, leading to more accurate surface treatment of the fabric.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0014] Reference Figure 1 A flat scraping bed adjustment mechanism for a fabric scraping machine includes an up-and-down adjustment assembly. The assembly includes a coarse adjustment section 1 and a fine adjustment section 2. The coarse adjustment section 1 adjusts the up-and-down movement of a scraper 3, while the fine adjustment section 2 tightens the scraper 3 and pushes its edge against the roller. Both the scraper 3 and the coarse adjustment section 1 are mounted on a support frame 4. The two ends of the scraper 3 are mounted on the support frame 4, with the coarse adjustment section 1 resting on the support frame 4 and abutting against the ends of the scraper 3. The fine adjustment section 2 is mounted on the support frame 4 and evenly distributed along the length of the scraper 3, also resting against the scraper 3. The coarse adjustment section 1 adjusts the relative position between the scraper 3 and the roller. When the scraper 3 is too long, causing the middle section to sag and the scraper 3 to bend, the fine adjustment section 2 pulls the scraper 3 back, offsetting the deformation caused by its excessive length. This ensures a more precise gap between the scraper 3 and the roller, allowing the stretched fabric to fully contact the roller when passing through this gap, resulting in more precise surface treatment of the fabric.

[0015] In this embodiment, the coarse adjustment part 1 includes a coarse adjustment sleeve 11, a coarse adjustment screw 12, and a rotating wrench 13. The coarse adjustment sleeve 11 is fixed on the support frame 4. The coarse adjustment screw 12 is inserted into the coarse adjustment sleeve 11 and passes through the coarse adjustment bar, pressing against the end of the scraper 3 and rotating with the end of the scraper 3. The coarse adjustment sleeve 11 has a thread inside that mates with the coarse adjustment screw 12. The rotating wrench 13 is fitted on the end of the coarse adjustment screw 12 away from the scraper 3. Pushing the rotating wrench 13 drives the coarse adjustment screw 12 to rotate, causing the scraper 3 to move up and down. The cooperation between the coarse adjustment thread and the coarse adjustment screw 12 can finely adjust the position of the scraper 3. If the scraper 3 is too long, the fine adjustment part 2 can be adjusted to pull back the scraper 3. The cooperation of the two sets of adjustment parts can achieve more precise adjustment of the scraper 3 and counteract the deformation caused by the excessive length of the scraper 3. This makes the gap between the scraper 3 and the roller more precise, so that when the fabric passes through the gap, the stretched fabric can make full contact with it, making the surface treatment of the fabric more precise.

[0016] In this embodiment, the fine-tuning unit 2 can be a fine-tuning cylinder 21. The fine-tuning cylinder 21 is fixed on the support frame 4, and its extension shaft abuts against the scraper 3. The fine-tuning cylinders 21 are spaced apart on the support frame 4 and evenly distributed along the length of the scraper 3. Each fine-tuning cylinder 21 can be controlled independently, allowing for precise adjustment to make the gap between the scraper 3 and the roller more accurate. When the fabric passes through this gap, the stretched fabric can fully contact the roller, resulting in more precise surface treatment of the fabric. The cooperation of two sets of adjustment units achieves more precise adjustment of the scraper 3, offsetting the deformation caused by the excessive length of the scraper 3. This makes the gap between the scraper 3 and the roller more accurate, ensuring that the stretched fabric can fully contact the roller when the fabric passes through this gap, resulting in more precise surface treatment of the fabric.

[0017] In this embodiment, a limiting waist hole can also be provided on the support frame 4. The end of the scraper 3 is inserted into the limiting waist hole. The limiting waist hole is arranged along the height direction of the support frame 4. The top opening of the limiting waist hole is used to pass through the coarse adjustment screw 12. The rotation of the coarse adjustment screw 12 drives the scraper 3 to move along the limiting waist hole. The purpose of providing the waist hole is to limit the stroke of movement.

[0018] The scraper 3 in this embodiment includes at least a back of blade 31 and a cutting edge 32. The end of the back of blade 31 is mounted on the support frame 4. A mounting groove is formed on one side of the back of blade 31, and the cutting edge 32 is inserted into the mounting groove. A fixing hole 33 is formed on the side wall of the mounting groove, and a corresponding hole is formed on the cutting edge 32, which is then fixed in the mounting groove with bolts. The cutting edge 32 can be easily disassembled and replaced when needed, making it more convenient to use.

[0019] Compared to existing technologies, this invention utilizes the cooperation of two sets of adjustment parts to achieve more precise adjustment of the scraper 3, offsetting the deformation caused by the excessive length of the scraper 3. This makes the gap between the scraper 3 and the roller more precise, ensuring that the stretched fabric can fully contact the roller when passing through this gap, resulting in more precise surface treatment of the fabric.

[0020] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
