Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a thermal cutting device for plastic strapping. Background Technology

[0002] A plastic strapping thermal cutting machine is a specialized device that uses heat energy to melt and cut plastic strapping. It mainly uses heating elements to generate high temperatures, causing the strapping to partially melt and break, achieving a fast and neat cutting effect. It is an indispensable practical tool in the modern packaging and logistics field.

[0003] When using a plastic cable tie thermal cutting machine to perform thermal melting cuts on plastic cable ties, the area of ​​the cable tie to be melted needs to be brought close to the thermal melting blade to melt the cable tie. However, if the operator is not focused enough, their hand may come into contact with the thermal melting blade, resulting in burns to the operator's hand. This reduces the safety performance of the plastic cable tie thermal cutting machine. Utility Model Content

[0004] This utility model proposes a plastic strapping thermal cutting device to address the problem that if operators are not focused enough during operation, their hands may come into contact with the hot melt blade, resulting in burns and reducing the safety performance of the plastic strapping thermal cutting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plastic strapping hot cutting device, comprising a base plate, an organism mounted on one side of the top of the base plate, connecting blocks mounted on one side of the top of the organism and the other side of the top of the base plate, a same hot melt blade detachably mounted in the middle of one side of the two connecting blocks, the hot melt blade being inclinedly arranged on the top of the base plate, a fan being fixedly mounted on the other side of the top of the organism, and a protective device provided on the top of the hot melt blade, the protective device blocking the two sides of the top of the hot melt blade by setting two baffles.

[0006] The effect achieved by the above components is as follows: by setting two baffles to block the two sides of the top of the hot melt blade, it is difficult for the operator to directly touch the hot melt blade when performing the hot melt blade to cut the cable tie. This helps to prevent the operator from touching the hot melt blade due to inattention or other reasons, and improves the safety of the cable tie hot cutting device.

[0007] Preferably, the protective device includes two baffles, which are symmetrically arranged on both sides of the hot melt blade. The two ends of the baffles are slidably installed on one side of the two connecting blocks, and connecting plates are symmetrically fixedly installed on the bottom of one side of the two connecting blocks. The baffles are arranged on the top of the connecting plates, and the same spring is fixedly installed on the side of the baffles and the connecting plates that are close to each other.

[0008] The effect achieved by the above components is as follows: the cable tie to be melted is placed on the two baffles, and at the same time, the two ends of the cable tie apply a force perpendicular to the direction of the baffle's inclination, causing the baffle to move towards the connecting plate. During this process, the cable tie will gradually approach the hot melt blade, and the baffle will compress the spring, causing the spring to deform until the cable tie touches the hot melt blade. Under the compression of the cable tie against the hot melt blade and the high temperature of the hot melt blade, the cable tie will melt. At this time, the baffle loses the external force, the spring will reset, and drive the baffle to move upward. Throughout the process, the two baffles will always block the hot melt blade, making it difficult for the operator's hand to touch the hot melt blade.

[0009] Preferably, the spring has a round rod inside, one end of which is fixedly installed at the bottom of the baffle, and the round rod is slidably installed on the inner wall of the connecting plate.

[0010] The effect achieved by the above components is that by setting up the round rod, the round rod can guide and limit the spring, which helps to prevent the spring from easily bending during deformation.

[0011] Preferably, a stop block is fixedly installed on each of the two springs on the side away from each other. The stop block is fixedly installed on one side of the baffle, and one side of the stop block is in contact with one side of the connecting plate.

[0012] The effect achieved by the above components is as follows: Since the spring is made of metal, it will also have a high temperature due to the influence of the hot melt blade. The stop block can block one side of the spring, which helps to prevent the operator's hand from touching the spring and causing burns.

[0013] Preferably, the baffle, connecting plate, and stop block are all made of high-temperature resistant transparent resin material, and the baffle, connecting plate, and stop block are made of resin material.

[0014] The effect achieved by the above components is that the resin material has poor thermal conductivity, and its surface can still maintain a relatively low temperature under the influence of the hot melt blade for a long time, thereby improving the overall safety performance of the hot melt cutting device.

[0015] Preferably, a fixing component is provided between the connecting plate and the baffle, a threaded pin is fixedly installed in the middle of the bottom of the connecting plate, the threaded pin is slidably installed on the inner wall of the connecting plate, and a nut is threadedly connected to the outer surface of the threaded pin, the nut being located at the bottom of the connecting plate.

[0016] The effect achieved by the above components is as follows: when the baffle moves toward the connecting plate, it will drive the threaded pin to slide synchronously on the inner wall of the connecting plate until one side of the connecting plate abuts against one side of the baffle. Then, the nut is rotated so that one side of the nut abuts against one side of the connecting plate, which can fix the baffle and the connecting plate. This allows the two baffles to be kept away from the hot melt blade, making it easier to maintain and replace the hot melt blade.

[0017] Preferably, a rubber pad is fixedly installed on one side of the nut, the rubber pad is disposed between the nut and the connecting plate, and the rubber pad is sleeved on the outer surface of the threaded rod.

[0018] The effect achieved by the above components is that by setting a rubber pad, the rubber pad can replace one side of the nut and abut against one side of the connecting plate, and increase the friction between the nut and the connecting plate, making the nut less likely to loosen.

[0019] Preferably, a round block is fixedly installed at one end of both the threaded pin and the round rod.

[0020] The effect achieved by the above components is that by setting a circular block at one end of the threaded pin and the round rod, one end of the threaded pin and the round rod can be blocked, which helps to prevent the threaded pin and the round rod from disengaging from the inner wall of the connecting plate due to misoperation.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, two baffles are set to block the two sides of the top of the hot melt blade. This makes it difficult for the operator to directly touch the hot melt blade when performing the hot melt blade operation on the cable tie. This helps to prevent the operator from touching the hot melt blade due to inattention or other reasons, and improves the safety of the cable tie hot cutting device. Attached Figure Description

[0029] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a plastic strapping thermal cutting device, including a base plate 1. A body 2 is mounted on one side of the top of the base plate 1. Connecting blocks 3 are mounted on one side of the top of the body 2 and the other side of the top of the base plate 1. A single hot melt blade 4 is detachably mounted in the middle of one side of each of the two connecting blocks 3. The hot melt blade 4 is obliquely positioned on the top of the base plate 1. The hot melt blade 4 is essentially a thermistor. A power supply module is installed inside the body 2, which can supply power to the hot melt blade 4 through a circuit to generate heat. A fan 5 (model such as Aimee) is fixedly mounted on the other side of the top of the body 2. The FA18-X115 is mainly used to blow away the fumes generated during the process of melting and cutting cable ties. The top of the hot melt blade 4 is equipped with a protective device 6. The protective device 6 blocks the two sides of the top of the hot melt blade 4 by setting two baffles 61. By setting two baffles 61 to block the two sides of the top of the hot melt blade 4, it is difficult for the operator to directly touch the hot melt blade 4 when performing the hot melt blade 4 melting and cutting operation on the cable ties. This helps to prevent the operator from touching the hot melt blade 4 due to inattention or other reasons, and improves the safety of the cable tie hot cutting device.

[0030] Reference Figure 2 and Figure 3As shown, the protective device 6 includes two baffles 61, which are symmetrically arranged on both sides of the hot melt blade 4. The two ends of the baffles 61 are slidably mounted on one side of two connecting blocks 3. Connecting plates 62 are symmetrically fixedly mounted on the bottom of one side of each of the two connecting blocks 3. The baffles 61 are positioned on top of the connecting plates 62. A spring 63 is fixedly mounted on the side of the baffles 61 and the connecting plates 62 that are close to each other. The cable tie to be melted is placed on the two baffles 61, and simultaneously, the two ends of the cable tie apply a force perpendicular to the inclined direction of the baffles 61, causing the baffles 61 to move towards the connecting plates 62. During this process, the cable tie gradually approaches the hot melt blade 4, and the baffles 61 compress the spring 63, causing the spring 63 to... The cable tie deforms until it touches the hot melt blade 4. Under the pressure of the cable tie on the hot melt blade 4 and the high temperature of the hot melt blade 4, the cable tie will melt and break. At this time, the baffle 61 loses the external force, the spring 63 will reset, and drive the baffle 61 to move upward. Throughout the process, the two baffles 61 will always block the hot melt blade 4, making it difficult for the operator's hand to touch the hot melt blade 4. The spring 63 is provided with a round rod 64 inside. One end of the round rod 64 is fixedly installed at the bottom of the baffle 61, and the round rod 64 is slidably installed on the inner wall of the connecting plate 62. By setting the round rod 64, the round rod 64 can guide and limit the spring 63, which helps to prevent the spring 63 from easily bending during the deformation process.

[0031] Reference Figure 2 and Figure 3 As shown, a stop block 65 is fixedly installed on the side of each of the two springs 63 that are far apart. The stop block 65 is fixedly installed on one side of the baffle 61, and one side of the stop block 65 is in contact with one side of the connecting plate 62. Since the spring 63 is made of metal, it will also have a high temperature due to the influence of the hot melt blade 4. The stop block 65 can shield one side of the spring 63, which helps to prevent the operator's hand from touching the spring 63 and causing burns. The baffle 61, the connecting plate 62 and the stop block 65 are all made of high temperature resistant transparent resin. By setting the baffle 61, the connecting plate 62 and the connecting block 3 made of resin, the thermal conductivity of the resin material is poor, and its surface can still maintain a relatively low temperature under the influence of the hot melt blade 4 for a long time, thereby improving the overall safety performance of the hot melt cutting device.

[0032] Reference Figure 4 and Figure 5As shown, a fixing component 7 is provided between the connecting plate 62 and the baffle 61. A threaded pin 71 is fixedly installed in the middle of the bottom of the connecting plate 62. The threaded pin 71 is slidably installed on the inner wall of the connecting plate 62. A nut 72 is threadedly connected to the outer surface of the threaded pin 71. The nut 72 is located at the bottom of the connecting plate 62. When the baffle 61 moves toward the connecting plate 62, it will drive the threaded pin 71 to slide synchronously on the inner wall of the connecting plate 62 until one side of the connecting plate 62 abuts against one side of the baffle 61. Then, the nut 72 is rotated so that one side of the nut 72 abuts against one side of the connecting plate 62, thereby fixing the baffle 61 and the connecting plate 62. This allows the two baffles 61 to be kept away from the hot melt blade 4, which facilitates the maintenance and replacement of the hot melt blade 4.

[0033] Reference Figure 4 and Figure 5 As shown, a rubber pad 73 is fixedly installed on one side of the nut 72. The rubber pad 73 is positioned between the nut 72 and the connecting plate 62 and is sleeved on the outer surface of the threaded rod. By setting the rubber pad 73, the rubber pad 73 can replace one side of the nut 72 to abut against one side of the connecting plate 62 and increase the friction between the nut 72 and the connecting plate 62, making it less likely for the nut 72 to loosen. A round block 74 is fixedly installed on one end of both the threaded pin 71 and the round rod 64. By setting the round block 74 on one end of the threaded pin 71 and the round rod 64, one end of the threaded pin 71 and the round rod 64 can be blocked, which helps to prevent the threaded pin 71 and the round rod 64 from disengaging from the inner wall of the connecting plate 62 due to misoperation.

[0034] Working principle: The cable tie to be melted is placed on two baffles 61, and simultaneously, a force perpendicular to the inclined direction of the baffles 61 is applied to both ends of the cable tie, causing the baffles 61 to move towards the connecting plate 62. During this process, the cable tie gradually approaches the hot melt blade 4, and the baffles 61 compress the spring 63, causing the spring 63 to deform until the cable tie touches the hot melt blade 4. Under the compression of the cable tie against the hot melt blade 4 and the high temperature of the hot melt blade 4, the cable tie will melt. At this time, the baffles 61 lose the external force, the spring 63 will return to its original position, and drive the baffles 61 to move upward. Throughout the process, the two baffles 61 always block the hot melt blade 4, making it difficult for the operator's hand to touch the hot melt blade 4; at the same time, the stop block 65 can... Spring 63 provides obstruction, and baffle 61, connecting plate 62, and connecting block 3 are all made of resin. Resin has poor thermal conductivity, and its surface can still maintain a relatively low temperature under the long-term influence of the hot melt blade 4, thereby further improving the overall safety performance of the hot melt cutting device. When the baffle 61 is pushed towards the connecting plate 62, the threaded pin 71 will slide synchronously on the inner wall of the connecting plate 62 until one side of the connecting plate 62 abuts against one side of the baffle 61. Then, the nut 72 is rotated so that the rubber pad 73 on one side of the nut 72 abuts against one side of the connecting plate 62, thus fixing the baffle 61 and the connecting plate 62. This allows the two baffles 61 to be kept away from the hot melt blade 4, facilitating the maintenance and replacement of the hot melt blade 4.
