[0014] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0015] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

Therefore, they should not be construed as limitations on this utility model.

[0016] like Figures 1 to 4As shown, a heat-sealing and cutting device for plastic bags with point breaks includes: a worktable 1, with multiple fixed frames 101 on the outer side of the worktable 1, each fixed frame 101 having a rotating roller 102 inside; and a processing assembly, disposed on the outer side of the worktable 1, for processing plastic bags. The processing assembly includes a support member 2 and a heat-melting component 3. The support member 2 is disposed on the outer side of the worktable 1 for mounting the heat-melting component 3, and the heat-melting component 3 is disposed inside the support member 2 for cutting the plastic bags. The support member 2, in conjunction with the heat-melting component 3, continuously processes the plastic bags. Specifically, when processing plastic bags is required, the roll of plastic bag to be processed is first mounted on the fixed frame 101 and rotating roller 102 at one end of the worktable 1, and the roll of plastic bag is then cut. The plastic bag is pulled from one end to the top of the workbench 1, passes under the processing component, and is finally fixed on the rotating roller 102 at the other end of the workbench 1. The servo motor on the outside of the fixing frame 101 is started, and the motor drives the rotating roller 102 to rotate. Through the winding action, the plastic bag moves continuously at a stable speed on the top of the workbench 1. During the movement, the support member 2 supports the heat-melting component 3 to work synchronously. The heating element 303 in the heat-melting component 3 heat-presses the plastic bag at the position that needs to be sealed. The cutter 304 cuts at the preset break point at the heat-sealed position to form a tear line that is easy to tear. Since the rotating roller 102 at both ends of the workbench 1 continuously winds up and unwinds, in conjunction with the real-time operation of the processing component, the heat sealing and cutting can be completed without pausing the movement of the plastic bag, realizing continuous processing.

[0017] like Figures 1 to 4 As shown, the support component 2 includes a support frame 201, and there are multiple support frames 201. The support frames 201 are arranged on both sides of the workbench 1. A rotating block 202 and a fixed plate 203 are arranged sequentially on the opposite side of the support frame 201. The rotating block 202 is rotatably connected to the support frame 201. The fixed plate 203 has a sliding groove 204 on the side opposite to the rotating block 202. There are multiple sliding grooves 204. Each of the opposite sides of the fixed plate 203 has a through groove 205. The through grooves 205 correspond one-to-one with the sliding grooves 204 and are connected to each other. Specifically, during use, the support frame 201 is fixed on both sides of the workbench 1. The rotating block 202 and the fixed plate 203 provide stable support. The motor on the outside of the support frame 201 transmits power to the rotating block 202 through the transmission box, driving the rotating block 202 to rotate at a set speed, which in turn drives the fixed plate 203 connected to it to rotate synchronously. The sliding groove 204 and the through groove 205 on the fixed plate 203 provide moving tracks for the sliding block 307 and the connecting block 206 of the hot melt component 3, respectively, ensuring that the hot melt component 3 can flexibly adjust its position along the track while rotating with the fixed plate 203, and always maintain precise contact with the moving plastic bag, thereby cooperating with the hot melt component 3 to complete continuous heat sealing and cutting operations, and ensuring processing stability.

[0018] like Figures 1 to 4As shown, the hot melt component 3 includes multiple sliding blocks 307, each corresponding to a sliding groove 204. The sliding blocks 307 slide within the sliding groove 204. Springs 306 are provided on the outer side of each sliding block 307. A connecting block 206 and a fixing block 302 are sequentially provided on the opposite side of each sliding block 307. The connecting block 206 slides within the through groove 205. A heating element 303 and a cutter 304 are respectively provided on the opposite side of the fixing block 302. Specifically, during the processing of the plastic bag, the fixing plate 203 rotates with the rotating block 202, causing the fixing block 302, heating element 303, and cutter 304 connected to the sliding block 307 to perform circular motion. When the heating element 303 and the cutter... When 304 rotates to the position of contact with the plastic bag, the fixed block 302 is pushed by the force, which drives the sliding block 307 to slide along the sliding groove 204 towards the plastic bag. At the same time, the connecting block 206 slides synchronously in the through groove 205 to ensure stable movement trajectory. At this time, the spring 306 on the outside of the sliding block 307 is compressed, generating a reverse elastic force, which not only ensures that the pressure of the heating element 303 and the cutter 304 on the plastic bag is moderate, avoiding pressure damage or insufficient contact, but also drives the sliding block 307 to reset when rotating out of contact. Through this process, the heating element 303 can make synchronous contact with the plastic bag in the direction of movement to achieve uniform heat sealing, while the cutter 304 precisely cuts out dotted lines with consistent intervals, completing the processing without stopping.

[0019] like Figures 1 to 4 As shown, a connecting rod 301 is also provided on one side of the opposite side of the fixed block 302. Specifically, during use, the connecting rod 301 connects the fixed blocks 302 on both sides laterally, so that multiple fixed blocks 302 form an integral structure. When the fixed plate 203 rotates or the sliding block 307 drives the fixed blocks 302 to move, the connecting rod 301 can ensure that the movement rhythm of all fixed blocks 302 is completely consistent, avoiding misalignment of the heating element 303 or the cutter 304 due to the offset of a single fixed block 302. For example, in the heat sealing stage, the connecting rod 301 can ensure that the heating elements 303 on both sides contact the corresponding positions of the plastic bag at the same time, ensuring that the heat sealing width is uniform. In the cutting stage, it can make the cutter 304 exert force synchronously, avoiding point breakage and line skew due to force on one side, thereby ensuring processing accuracy.

[0020] like Figures 1 to 4As shown, the sliding block 307 is also equipped with a guide rod 305 inside. The guide rod 305 slides on the outside of the sliding block 307 and is connected to the fixed plate 203. Specifically, during use, one end of the guide rod 305 is fixed to the fixed plate 203, and the other end passes through the sliding block 307 and is slidably connected to it. Together with the sliding groove 204, it forms a double guide structure. When the sliding block 307 slides along the sliding groove 204 under the action of the spring 306, the guide rod 305 can restrict the movement direction of the sliding block 307 to prevent it from deviating or rotating due to uneven force. For example, when the heating element 303 contacts the plastic bag and generates a reaction force, the guide rod 305 can ensure that the sliding block 307 only moves in a straight line direction close to or away from the plastic bag, avoiding non-perpendicular contact between the heating element 303 or the cutter 304 and the plastic bag, thereby ensuring the heat sealing quality and the regularity of the point break line, while reducing component wear and extending the service life of the device.

[0021] like Figures 1 to 4 As shown, the working state of the heat-sealing and cutting device for point-cutting of plastic bags is as follows: During use, the plastic bag is first placed on the top of the worktable 1 through the cooperation of the fixed frame 101 and the rotating roller 102. Then, the heating element 303 and the cutter 304 are driven to contact the plastic bag through the rotating block 202 and the fixed plate 203, thereby realizing the continuous processing of plastic.

[0022] In summary, this utility model includes: a workbench 1, with multiple fixed frames 101 on the outer side of the workbench 1, each fixed frame 101 having a rotating roller 102 inside; and a processing assembly, located on the outer side of the workbench 1, for processing plastic bags. The processing assembly includes a support member 2 and a heat-melting component 3. The support member 2 is located on the outer side of the workbench 1 and is used to install the heat-melting component 3. The heat-melting component 3 is located inside the support member 2 and is used to cut the plastic bags. The support member 2 works in conjunction with the heat-melting component 3 to continuously process the plastic bags. Through the arrangement of the support member 2 and the heat-melting component 3, this utility model achieves the processing of continuously moving plastic bags by coordinating the support frame 201, rotating block 202, fixed plate 203, sliding groove 204, through groove 205, connecting block 206, connecting rod 301, fixed block 302, and sliding block 307, controlling the heating element 303 and the cutter 304. This allows the plastic bags to move continuously, improving the production speed of plastic bags.
