Description

Technical Field

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

[0002] A tablecloth cutting machine is a specialized piece of equipment used to cut tablecloth raw materials. It can efficiently and accurately cut the fabric into the required size and shape and is widely used in tablecloth production lines.

[0003] When cutting tablecloths using a cutting machine, the tablecloth is placed on a conveyor belt. A motor is then started to rotate a cylindrical shaft, which in turn rotates the conveyor belt, transporting the tablecloth to the sliding frame. The internal drive mechanism of the sliding frame then activates, moving the cutting blade left and right to cut the tablecloth. This drive mechanism can be a motor-driven lead screw or a cylinder, so there is no fixed limitation. After cutting, another motor is started to rotate another cylindrical shaft and conveyor belt, conveying the cut tablecloth out. During the cutting process, if the sharpness of the cutting blade decreases, wrinkles or misalignments may occur in the fabric, affecting cutting accuracy and fabric neatness, thus reducing production efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that if the sharpness of the cutting part of the cutting blade decreases during the cutting process, it may cause wrinkles or misalignment of the fabric, affecting the cutting accuracy and the neatness of the fabric, thereby reducing production efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a tablecloth cutting machine, including a cutting machine body, a sliding frame provided on one side of the cutting machine body, a cutting blade slidably installed on the inner wall of the sliding frame, one end of the cutting blade inserted into the inner wall of the cutting machine body, a plurality of round shafts symmetrically installed through the inner wall of the cutting machine body, a conveyor belt sleeved on the outer surface of the round shafts, a motor symmetrically fixedly installed on one side of the cutting machine body, wherein the output end of the motor is fixedly connected to one side of the round shafts by means of a coupling, and a limit device is provided on both sides of the sliding frame. The limit device can drive the pressure rod to move downward through an electric telescopic rod, thereby limiting and fixing the tablecloth inside the sliding frame.

[0006] The aforementioned components achieve the following effect: During the production and processing of tablecloths, when the tablecloth is cut using the main body of the cutting machine, it is placed on a conveyor belt. Then, the motor is started to drive the rotating shaft, which in turn drives the conveyor belt to rotate, transporting the tablecloth into the sliding frame. Then, the limiting device presses the two sides of the tablecloth at the cutting position onto one side of the main body of the cutting machine. This prevents the tablecloth from wrinkling or misaligning even if the cutting edge of the cutting blade is not sharp enough during the cutting process, effectively improving the cutting accuracy, neatness, and production effect. At this time, the drive mechanism inside the sliding frame is started to drive the cutting blade to move left and right to cut the tablecloth. The drive mechanism can be a motor-driven lead screw or a cylinder-driven mechanism, so there is no fixed limitation. After the cutting process is completed, another motor is started to drive another rotating shaft and transmission belt to rotate, conveying the cut tablecloth out.

[0007] Preferably, the limiting device includes a groove frame, with a detachable mechanism between one end of the groove frame and one side of the sliding frame; an electric telescopic rod, with one end of the electric telescopic rod fixedly installed on one side of the groove frame; and a pressure rod, with one side of the pressure rod fixedly installed on the output end side of the electric telescopic rod.

[0008] The effect achieved by the above components is as follows: by setting a limiting device, after the tablecloth is transported into the sliding frame, the electric telescopic rod on the groove frame can be activated to drive the pressure rod to move downward, pressing the two sides of the tablecloth onto one side of the main body of the cutting machine, limiting and fixing the tablecloth located on both sides of the cutting blade. In this way, if the cutting edge of the cutting blade is not sharp enough during the cutting process, the tablecloth will not wrinkle or misalign. This effectively improves the accuracy and neatness of the cutting and the production effect.

[0009] Preferably, a limiting rod is symmetrically fixedly installed on one side of the pressure rod, and one end of the limiting rod is installed through the outer surface of the limiting rod on one side of the groove frame.

[0010] The effect achieved by the above components is that by setting the limiting rod, the two ends of the pressure rod can be slidably installed on one side of the groove frame, so that the pressure rod is not easy to shake when moving up and down, and the movement is more stable.

[0011] Preferably, a reinforcing rod is symmetrically fixedly installed on the outer surface of the output end of the electric telescopic rod, and one side of the reinforcing rod is fixedly installed on one side of the pressure rod.

[0012] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the output end of the electric telescopic rod and the pressure rod can be increased, making the connection more secure and less prone to breakage or damage.

[0013] Preferably, an anti-slip block is fixedly installed on one side of the pressure rod, and the anti-slip block is made of rubber.

[0014] The effect achieved by the above components is as follows: by setting anti-slip blocks, the contact friction on one side of the pressure bar can be increased, making it more secure when pressed against the surface of the tablecloth, and the tablecloth is less likely to loosen at the bottom of the pressure bar, thus improving the limiting and fixing effect.

[0015] Preferably, the detachable mechanism includes a locking block, one end of which is slidably mounted in the inner wall of one side of the groove frame. Rectangular grooves are provided on both sides of the sliding frame, and a locking hole is provided on one side of the inner wall of the rectangular groove. One end of the groove frame and one end of the locking block are respectively inserted into the inner walls of the rectangular groove and the locking hole. A spring is also included, with both ends of the spring being fixedly mounted on one side of the inner wall of the groove frame and one side of the locking block.

[0016] The effect achieved by the above components is as follows: by setting a detachable mechanism, when it is necessary to maintain or replace the groove frame and pressure rod, the locking block can be manually pressed down to a certain position in the inner wall of the groove frame, causing the spring to contract and pull one end out of the locking hole. Then, the groove frame can be pulled to the other end to pull it out of the rectangular groove and then removed from the sliding frame for easy replacement and maintenance.

[0017] Preferably, one end of the groove frame has a trapezoidal cross-section.

[0018] The effect achieved by the above-mentioned components is that by setting one end of the groove bracket in a trapezoidal shape, the area of ​​one end of the groove bracket can be reduced, so that it can be quickly aligned with the rectangular groove and inserted during installation, which facilitates installation.

[0019] Preferably, the detachable mechanism further includes a support telescopic rod, wherein the outer surface of the support telescopic rod is installed through the inner wall of the spring, and both ends are respectively fixedly installed on one side of the inner wall of the groove frame and one side of the locking block.

[0020] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use.

[0021] The beneficial effects of this utility model are:

[0022] By setting a limiting device, after the tablecloth is transported into the sliding frame, the electric telescopic rod on the groove frame can be activated to drive the pressure rod downward, pressing it onto one side of the main body of the cutting machine. This limits and fixes the tablecloth located on both sides of the cutting blade. In this way, if the cutting edge of the cutting blade is not sharp enough during the cutting process, the tablecloth will not wrinkle or misalign. This effectively improves the accuracy and neatness of the cutting and the production effect. Attached Figure Description

[0032] Figure 1-5The tablecloth cutting machine shown includes a cutting machine body 1. A sliding frame 3 is provided on one side of the cutting machine body 1. A cutting blade 4 is slidably installed on the inner wall of the sliding frame 3. One end of the cutting blade 4 is inserted into the inner wall of the cutting machine body 1. Several round shafts 5 are symmetrically installed through the inner wall of the cutting machine body 1. A conveyor belt 6 is sleeved on the outer surface of the round shafts 5. A motor 7 is symmetrically fixed on one side of the cutting machine body 1. The output end of the motor 7 is fixedly connected to one side of the round shafts 5 by means of a coupling. Limiting devices 2 are provided on both sides of the sliding frame 3. The limiting devices 2 can drive the pressure rod 24 to move downward through the electric telescopic rod 23, thereby limiting and fixing the tablecloth inside the sliding frame 3. When the tablecloth is cut using the main body 1 of the cutting machine, the tablecloth is placed on the conveyor belt 6. Then, the motor 7 is started to drive the round shaft 5 to rotate, which in turn drives the conveyor belt 6 to rotate, transporting the tablecloth into the sliding frame 3. Then, the limiting device 2 presses the two sides of the tablecloth at the cutting position onto one side of the main body 1 of the cutting machine. This prevents the tablecloth from wrinkling or misaligning even if the cutting blade 4 is not sharp enough during the cutting process, effectively improving the cutting accuracy, neatness, and production effect. At this time, the drive mechanism inside the sliding frame 3 is started to drive the cutting blade 4 to move left and right to cut the tablecloth. The drive mechanism can be driven by the motor 7 with a lead screw or by a cylinder, so there is no fixed limitation. After the cutting is completed, another motor 7 is started to drive another round shaft 5 and the transmission belt to rotate, conveying the cut tablecloth out.

[0033] Figure 1-5 The limiting device 2 shown includes a groove frame 21, with a detachable mechanism 22 between one end of the groove frame 21 and one side of the sliding frame 3; an electric telescopic rod 23, one end of which is fixedly installed on one side of the groove frame 21; and a pressure rod 24, one side of which is fixedly installed on the output end of the electric telescopic rod 23. By setting the limiting device 2, after the tablecloth is transported into the sliding frame 3, the electric telescopic rod 23 on the groove frame 21 can be activated to drive the pressure rod 24 downward, pressing both sides of the tablecloth onto one side of the cutting machine body 1, thus limiting and fixing the tablecloth located on both sides of the cutting blade 4. In this way, even if the cutting edge of the cutting blade 4 is not sharp during the cutting process, the tablecloth will not wrinkle or misalign, effectively improving the cutting accuracy, neatness, and production effect.

[0034] Figure 1-5A limiting rod 25 is symmetrically fixedly installed on one side of the pressure rod 24. One end of the limiting rod 25 is mounted through the outer surface of one side of the groove frame 21. By setting the limiting rod 25, both ends of the pressure rod 24 can be slidably mounted on one side of the groove frame 21, preventing the pressure rod 24 from wobbling during up-and-down movement and making the movement more stable. A reinforcing rod 26 is symmetrically fixedly installed on the outer surface of the output end of the electric telescopic rod 23. One side of the reinforcing rod 26 is fixedly installed on one side of the pressure rod 24. By setting the reinforcing rod 26, the connection area between the output end of the electric telescopic rod 23 and the pressure rod 24 can be increased, making the connection more secure and less prone to breakage. An anti-slip block 27, made of rubber, is fixedly installed on one side of the pressure rod 24. By setting the anti-slip block 27, the contact friction on one side of the pressure rod 24 can be increased, making it more secure when pressed against the surface of the tablecloth, preventing the tablecloth from loosening at the bottom of the pressure rod 24, and improving the limiting and fixing effect.

[0035] Figure 1-5 The detachable mechanism 22 shown includes a locking block 224, one end of which is slidably mounted in the inner wall of one side of the groove frame 21. Rectangular slots 221 are provided on both sides of the sliding frame 3, and a locking hole 222 is provided on one side of the inner wall of each rectangular slot 221. One end of the groove frame 21 and one end of the locking block 224 are respectively inserted into the inner walls of the rectangular slot 221 and the locking hole 222. A spring 223 is also included, with both ends of the spring 223 fixedly mounted on one side of the inner wall of the groove frame 21 and one side of the locking block 224. By providing the detachable mechanism 22, when maintenance or replacement of the groove frame 21 and the pressure rod 24 is required, the locking block 224 can be manually pressed downwards into the inner wall of the groove frame 21 to a certain position, causing the spring 223 to contract and one end to be pulled out of the locking hole 222. Then, by pulling the groove frame 21 to one end, it can be pulled out of the rectangular slot 221 and removed from the sliding frame 3 for easy replacement and maintenance.

[0036] Figure 1-5 The groove bracket 21 shown has a trapezoidal cross-section at one end. By making one end of the groove bracket 21 trapezoidal, the area of ​​one end of the groove bracket 21 can be reduced, allowing it to be quickly aligned with the rectangular slot 221 and inserted during installation, thus facilitating installation. The detachable mechanism 22 also includes a support telescopic rod 225, the outer surface of which is installed through the inner wall of the spring 223, and both ends are fixedly installed on one side of the inner wall of the groove bracket 21 and one side of the locking block 224, respectively. By setting the telescopic rod, the inner wall of the spring 223 can be supported and reinforced, making it less prone to damage during use.

[0037] Working principle: During the production and processing of the tablecloth, when the tablecloth is cut by the main body 1 of the cutting machine, the tablecloth is placed on the conveyor belt 6. Then, the motor 7 is started to drive the round shaft 5 to rotate, which in turn drives the conveyor belt 6 to rotate, transporting the tablecloth into the sliding frame 3. Then, the electric telescopic rod 23 on the groove frame 21 is activated to drive the pressure rod 24 to move downward. The limiting rods 25 at both ends slide downward on one side of the groove frame 21, pressing the two sides of the tablecloth against one side of the main body 1 of the cutting machine, thus limiting and fixing the tablecloth located on both sides of the cutting blade 4. This design ensures that even if the cutting blade 4 is not very sharp during the cutting process, the tablecloth will not wrinkle or misalign. This effectively improves the accuracy, neatness, and production efficiency of the cutting. At this point, the drive mechanism inside the sliding frame 3 is activated to move the cutting blade 4 left and right to cut the tablecloth. The drive mechanism can be a motor 7 driving a lead screw or a cylinder, so there is no fixed limitation. After the cutting process is completed, another motor 7 is activated to drive another round shaft 5 and the transmission belt to rotate, thus conveying the cut tablecloth out.

[0038] When it is necessary to maintain or replace the groove frame 21 and the pressure rod 24, the locking block 224 can be manually pressed down into the inner wall of the groove frame 21 to a certain position, causing the spring 223 to contract and pull one end out of the locking hole 222. Then, the groove frame 21 can be pulled out from the rectangular groove 221 and removed from the sliding frame 3 for easy replacement and maintenance.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
