Description

Technical Field

[0003] In the existing heat-sealing device, the tension of the protective clothing is often controlled manually during the heat-sealing process. However, due to the uneven experience of the heat-sealing workers themselves, the control effect of the tension is extremely unstable. Some workers are inexperienced and find it difficult to accurately grasp the appropriate tension, which may make the protective clothing too loose, which may easily cause wrinkles, poor fit and other undesirable phenomena during heat-sealing, seriously affecting the heat-sealing quality. Although some workers have certain experience, there may be operational deviations, which may make the protective clothing too tight, which not only easily damages the material, but also may affect the subsequent performance. This method of relying on manual experience to control the tension greatly limits the improvement of heat-sealing efficiency and quality, and in large-scale production, this uncertainty will bring more quality risks and increased costs.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the practical embodiment clearer, the technical solution in the practical embodiment is clearly and completely described. Obviously, the described embodiment is a part of the practical embodiment, not all of the embodiments. Based on the embodiments in this practical, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical.

[0024] The embodiment of the present application provides a heat-sealing device for protective clothing production, which solves the technical problem that it is inconvenient to control the tension of the protective clothing during heat-sealing, and it is difficult to ensure the accuracy and consistency of the heat-sealing position. In actual use, the tension of the protective clothing is controlled during heat-sealing, and the accuracy and consistency of the heat-sealing position are ensured.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-6, a heat sealing device for protective clothing production, comprising: a heat sealing device body 1, used for heat sealing a sealing strip and protective clothing; a heat sealing wheel 2, located on the heat sealing device body 1, and the heat sealing wheel 2 is used for heat sealing a sealing strip and protective clothing; two movable parts 3 are provided, and the movable parts 3 are located on the heat sealing device body 1 and are located on both sides of the heat sealing wheel 2; a plurality of threaded rods 4 are provided, and the threaded rods 4 are located on both sides of the movable part 3, and the threaded rods 4 are meshed and connected with the motor in the movable part 3 through a gear set 9; a plurality of auxiliary parts 5 are provided, and the auxiliary parts 5 are located on the threaded rod 4, and the auxiliary parts 5 are threadedly connected to the threaded rod 4; a plurality of tensioning wheels 6 are provided, and the tensioning wheels 6 are located on the auxiliary parts 5, and the tensioning wheels 6 are rotatably connected to the auxiliary parts 5; a connecting part 101 is firmly connected to the heat sealing device body 1 and is located on both sides of the heat sealing wheel 2; an auxiliary roller 102 is rotatably connected to the connecting part 101, and the auxiliary roller 102 is adapted to the tensioning wheel 6.

[0027] Through the mutual cooperation between the above-mentioned structures, the tension of the protective clothing during heat sealing can be controlled to ensure that the protective clothing remains flat and appropriately tensioned during the heat sealing process to avoid wrinkles or sagging.

[0028] There are multiple limit rods 301, one end of which is firmly connected to the movable part 3, and the other end passes through the auxiliary part 5. The limit rods 301 are located on both sides of the threaded rod 4 to limit the rotation of the auxiliary part 5.

[0029] The limiting rod 301 can prevent the auxiliary component 5 from rotating along with the threaded rod 4 , thereby preventing the tensioning wheel 6 from rotating along with the threaded rod 4 .

[0030] The sliding member 302 is stably connected below the movable member 3, and the sliding member 302 is slidably connected to the heat sealing device body 1; the screw rod 8 is stably connected inside the heat sealing device body 1, and the screw rod 8 is threadedly connected to the sliding member 302, for driving the sliding member 302 to move.

[0031] The position of the movable part 3 can be adjusted by the mutual cooperation between the sliding parts 302 through the threaded rod 4.

[0032] The detection device 7 is located on the top of the movable part 3, and the detection device 7 is firmly connected to the movable part 3. The detection device 7 is used to detect the position of the sewing line of the protective clothing.

[0033] The detection device 7 can detect the position of the sewing line of the protective clothing so as to perform accurate heat sealing.

[0034] The friction force of the auxiliary roller 102 surface on the protective clothing is smaller than the friction force of the tensioning wheel 6 surface on the protective clothing.

[0035] The friction force of the auxiliary roller 102 surface on the protective clothing is smaller than that of the tensioning wheel 6 surface on the protective clothing, so that the tensioning wheel 6 can better play the tensioning role, while the auxiliary roller 102 mainly plays the role of auxiliary pressing and matching.

[0036] The total length of the auxiliary roller 102 is greater than the maximum distance between two tensioning wheels 6 .

[0037] The total length of the auxiliary roller 102 is greater than the maximum distance between the two tensioning wheels 6, which can ensure that the auxiliary roller 102 can fully contact the protective clothing and play a better auxiliary role.

[0038] One end of the threaded rod 4 outside the movable part 3 is connected to a limiting member for preventing the auxiliary part 5 from being separated from the threaded rod 4 .

[0039] The limiting member can prevent the auxiliary member 5 from accidentally disengaging from the threaded rod 4, thereby ensuring the normal operation of the device.

[0040] The detection device 7 is located on the movable part 3 at the feeding end of the heat sealing wheel 2 .

[0041] The detection device 7 is located on the movable part 3 at the feeding end of the heat sealing wheel 2, and can detect the position of the suture line in advance to prepare for the subsequent heat sealing operation.

[0042] During use, when the heat sealing device for the production of protective clothing is used, the sealing strip and protective clothing to be heat sealed are first placed on the heat sealing device body 1, and passed between the heat sealing wheel 2 and the auxiliary roller 102; the motor is started, and the threaded rod 4 is driven to rotate through the gear set 9, so that the auxiliary part 5 moves on the threaded rod 4, thereby adjusting the position of the tensioning wheel 6 to tension the protective clothing; at this time, the tensioning wheel 6 and the auxiliary roller 102 work together to keep the protective clothing flat and moderately tensioned; during the heat sealing process, the detection device 7 detects the position of the sewing line of the protective clothing in real time and feeds back the information to the control system; the control system drives the sliding part 302 to move through the screw 8 according to the detection result, and then adjusts the activity The position of the movable part 3 is adjusted so that the movable part 3 can drive the protective clothing to move through the cooperation of the tension wheel 6 and the auxiliary roller 102, so that the suture line is accurately aligned with the position of the heat sealing wheel 2; when the suture line moves to the appropriate position, the heat sealing wheel 2 applies pressure and drives the protective clothing to move, thereby heat-sealing the sealing strip to the protective clothing; during the heat sealing process, the limit rod 301 limits the rotation of the auxiliary part 5 to ensure that it can only move along the threaded rod 4; at the same time, the total length of the auxiliary roller 102 is greater than the maximum distance between the two relative tension wheels 6, ensuring that the auxiliary roller 102 can fully contact the protective clothing and play a better auxiliary role; when the heat sealing is completed, the motor is turned off, and the heat sealing wheel 2 stops heating and applying pressure. The operator takes out the heat-sealed protective clothing and proceeds with the subsequent production process.

[0043] The control system, protective device, driving device and tension detection structure required in the above-mentioned device all belong to the existing technology and are non-essential technical features in this application, so they are not described or drawn in the documents and drawings of this application.

[0044] In summary, compared with the prior art, the present invention has the following beneficial effects: through the cooperation of the tensioning wheel and the auxiliary roller, the protective clothing can be kept flat and moderately tensioned during the heat sealing process to avoid wrinkles or looseness, thereby improving the quality and effect of heat sealing; the detection device can accurately detect the position of the seam line of the protective clothing, and drive the tensioning wheel to move through the sliding part and the movable part, so that the seam line is in the center position of the heat sealing wheel, thereby ensuring the accuracy and consistency of the heat sealing position; the design also improves the heat sealing efficiency, reduces production costs, and improves the degree of production automation.
