Description

Technical Field

[0001] This utility model relates to the field of timer switches, and in particular to a timer start device for a shaping device for embroidered lace fabrics. Background Technology

[0002] The embroidered lace fabric setting device is a device used to set the shape of embroidered lace fabrics. It uses a hot-pressing heating plate on a hot-pressing frame to heat-press the embroidered fabric placed on the work platform, so as to use high temperature to set the shape of the fabric.

[0003] The equipment used for fabric setting in production units is usually kept on for long periods of time for convenience, which leads to a high rate of equipment damage. However, the fabric setting equipment in many positions is used intermittently, which increases the unnecessary cost of spare parts procurement and maintenance manpower.

[0004] Therefore, given that the fabric setting equipment in the aforementioned positions is usually used intermittently but is kept on for extended periods for convenience, thus increasing the damage rate of the fabric setting equipment to some extent, a timed start device for embroidered lace fabric setting equipment can be designed. This device uses a high-resistance block to allow the fabric setting equipment to operate at low power under normal conditions. When the external motor switch is pressed, the low-resistance block contacts the conductive disc within a limited time, allowing the fabric setting equipment to operate at full power for a limited time. This solves the aforementioned problem while saving the preheating time of the fabric setting equipment. Utility Model Content

[0005] In order to overcome the problem that the fabric setting equipment in the above-mentioned positions is usually used intermittently, but is kept on for a long time for convenience, which to some extent increases the damage rate of the fabric setting equipment.

[0006] The technical solution of this utility model is as follows: a timing start device for a shaping device of embroidered lace fabric, including a wheel frame; and a high-resistance block. Two partitions are fixed inside the wheel frame, and a high-resistance block is fixed between the two partitions. A low-resistance block is fixed outside the two partitions. Conductive discs are provided on both sides of the high-resistance block. A rigid input wire is fixed on one side of the conductive disc, and a rigid output wire is fixed on the other side of the conductive disc. Wires are installed inside both the rigid input and rigid output wires. An upper gear is fixed to one side of the wheel frame via a connecting shaft. A clockwork timer is installed on one side of the upper gear. A compound gear meshes with the lower end of the upper gear. A servo motor is installed on one side of the compound gear. A passive stop block is provided at the rear end of the lower end of the compound gear, and a built-in motor switch is installed at the rear end of the passive stop block.

[0007] Preferably, the power switch is connected to the power supply, and the rigid output conduit is connected to the fabric setting device. Under normal conditions, both conductive discs are in contact with the high-resistance block to reduce the voltage when current enters the fabric setting device after passing through the high-resistance block, thereby reducing the operating power of the fabric setting device and preventing it from operating at full power. Only the heating platen of the fabric setting device is kept at a relatively low temperature. When the user needs to use the fabric setting device, pressing the external motor switch causes the servo motor to rotate the compound gear forward, which in turn rotates the upper gear until the active stop block touches the internal motor switch, thus shutting off the servo motor. The power is stopped, and then the clockwork timer causes the upper gear to rotate slowly and uniformly. The upper gear then causes the compound gear to rotate slowly and uniformly in reverse. Before the active stop block re-contacts the front end of the passive stop block due to the reversal of the compound gear, the blocks in contact with the conductive disk will change from high-resistance blocks to low-resistance blocks. This allows the current to enter the fabric setting equipment with a higher voltage after passing through the low-resistance blocks, enabling the fabric setting equipment to operate at a higher power. This allows the hot pressing heating plate of the fabric setting equipment to be heated to its maximum temperature. The clockwork timer also limits the time for the high-resistance blocks to re-contact the conductive disk, thus achieving a timed switch between high-power operation and low-power operation of the fabric setting equipment.

[0008] Preferably, the compound gear consists of a lower gear, a fixed disk, and a driving stop block. The lower gear meshes with the lower end of the upper gear, the fixed disk is fixed to one side of the lower gear, and the driving stop block is fixed to the lower end of the fixed disk.

[0009] Preferably, the conductive disk is located on the inner side of the wheel frame, and the conductive disk is slidably connected to the wheel frame, while the servo motor is electrically connected to the built-in motor switch.

[0010] Preferably, a power switch is fixedly connected to one side of the front end of the rigid input conduit, and the power switch is electrically connected to a conductive disk on one side through the wire inside the rigid input conduit. An external motor switch is electrically connected to the front end of the servo motor.

[0011] Preferably, multiple annular heat dissipation fins are fixed to the outer side of the wheel rim, a first housing is installed on the outer side of the servo motor, a second housing is installed on one side of the first housing, and a heat dissipation groove is opened at the upper end of the second housing.

[0012] Preferably, the wheel rim is installed in the heat dissipation groove, and the wheel rim is rotatably connected to the second housing, while the lower end face of the passive abutment is fixedly connected to the first housing.

[0013] Preferably, a rigid input conduit passes through the front end face of the first housing and is fixedly connected to the first housing, and a rigid output conduit passes through the side end face of the second housing and is fixedly connected to the second housing. The external motor switch and the power switch are both installed on the front end face of the first housing.

[0014] The beneficial effects of this utility model are:

[0015] By configuring the wheel frame, high-resistance block, low-resistance block, and clockwork timer, both conductive discs are normally in contact with the high-resistance block. This reduces the voltage of the current entering the fabric setting equipment after passing through the high-resistance block, thus lowering the operating power of the fabric setting equipment. This prevents the equipment from operating at full power, keeping only the heating platen at a relatively low temperature. When the user needs to use the fabric setting equipment, pressing the external motor switch activates the servo motor to rotate the compound gear forward, which in turn rotates the upper gear until the active stop block contacts the internal motor switch. This shuts down the servo motor and stops applying force. The clockwork timer then causes the upper gear to slowly and uniformly rotate back, which in turn causes the compound gear to slowly and uniformly rotate backward. The active stop block then re-engages with the passive stop block due to the reverse rotation of the compound gear. Before the front end of the device contacts the conductive disk, the high-resistance block changes to a low-resistance block. This allows the current to flow through the low-resistance block and enter the fabric setting equipment with a higher voltage, enabling the fabric setting equipment to operate at higher power. This allows the hot-pressing heating plate of the fabric setting equipment to be heated to its maximum temperature. The spring-loaded timer limits the time when the high-resistance block re-contacts the conductive disk, enabling the fabric setting equipment to switch from high-power operation to low-power operation at a timed interval. This avoids the equipment operating at high temperature and high power for a long time, reducing the aging rate and the probability of damage. Furthermore, the hot-pressing heating plate of the fabric setting equipment does not need to be heated from ambient temperature to the maximum temperature during use, but rather from a relatively lower temperature to the maximum temperature, saving preheating time and improving both efficiency and ease of operation.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment: a timed start device for shaping embroidered lace fabric, including a wheel frame 1; it also includes a high-resistance block 3. Two partitions 2 are fixedly connected inside the wheel frame 1, and the high-resistance block 3 is fixedly connected between the two partitions 2. A low-resistance block 4 is fixedly connected to the outside of the two partitions 2. Conductive disks 5 are provided on both sides of the high-resistance block 3. A rigid input wire conduit 6 is fixedly connected to one conductive disk 5, and a rigid output wire conduit 7 is fixedly connected to the other conductive disk 5. Wires are installed inside both the rigid input wire conduit 6 and the rigid output wire conduit 7. One side of the wheel frame 1 is open to… An upper gear 8 is fixedly connected to a connecting shaft. A spring-loaded timer 9 is installed on one side of the upper gear 8. A compound gear 10 meshes with the lower end of the upper gear 8. A servo motor 11 is installed on one side of the compound gear 10. A passive stop block 12 is provided at the rear end of the lower end of the compound gear 10. An internal motor switch 13 is installed at the rear end of the passive stop block 12. The power switch 15 is connected to the power supply, and the rigid output cable 7 is connected to the fabric setting equipment. Under normal conditions, both conductive discs 5 are in contact with the high-resistance block 3 to reduce the voltage when the current enters the fabric setting equipment after passing through the high-resistance block 3, thereby reducing the fabric setting voltage. The operating power of the equipment is adjusted so that the fabric setting equipment does not operate at full power, but only keeps the heating plate of the fabric setting equipment at a relatively low temperature. When the user needs to use the fabric setting equipment, pressing the external motor switch 14 causes the servo motor 11 to rotate the compound gear 10 in the forward direction, and the compound gear 10 causes the upper gear 8 to rotate until the active stop block 1003 touches the internal motor switch 13, which then stops the servo motor 11 from exerting force. Subsequently, the spring timer 9 causes the upper gear 8 to slowly and uniformly rotate back, and the upper gear 8 then causes the compound gear 10 to slowly and uniformly rotate back. In the rapid reversal, before the active stop block 1003 re-contacts the front end face of the passive stop block 12 due to the reversal of the compound gear 10, the blocks in contact with the conductive disk 5 will change from high resistance block 3 to low resistance block 4. This allows the current to enter the fabric setting equipment with a higher voltage after passing through the low resistance block 4, enabling the fabric setting equipment to operate at a higher power. This allows the hot pressing heating plate of the fabric setting equipment to be heated to its maximum temperature. Meanwhile, the spring timer 9 limits the time for the high resistance block 3 to re-contact the conductive disk 5, thus realizing the timed switching of the fabric setting equipment from high power operation to low power operation.

[0024] Please see Figures 1-3In this embodiment, the compound gear 10 consists of a lower gear 1001, a fixed disk 1002, and a driving stop 1003. The lower gear 1001 meshes with the lower end of the upper gear 8. The fixed disk 1002 is fixed to one side of the lower gear 1001. The driving stop 1003 is fixed to the lower end of the fixed disk 1002. The conductive disk 5 is disposed on the inner side of the wheel frame 1 and is slidably connected to the wheel frame 1. The servo motor 11 is electrically connected to the built-in motor switch 13. The conductive disk 5 is used to contact the high-resistance block 3 or the low-resistance block 4. It is connected to the rigid input conduit 6 or the rigid output conduit 7 to realize the circuit connection. A power switch 15 is fixedly connected to one side of the front end of the rigid input conduit 6, and the power switch 15 is electrically connected to the conductive disk 5 on one side through the wire in the rigid input conduit 6. An external motor switch 14 is electrically connected to the front end of the servo motor 11. The power switch 15 is used to control the disconnection and connection of the circuit between the fabric shaping equipment and the power supply. The external motor switch 14 is used together with the built-in motor switch 13 to control the operation and shutdown of the servo motor 11.

[0025] Please see Figures 4-5 In this embodiment, a plurality of annular heat dissipation fins 16 are fixedly connected to the outer side of the wheel frame 1. A first housing 17 is installed on the outer side of the servo motor 11. A second housing 18 is installed on one side of the first housing 17. A heat dissipation groove 19 is provided at the upper end of the second housing 18. The heat dissipation groove 19 and the annular heat dissipation fins 16 are used to accelerate the heat dissipation of the wheel frame 1, the high resistance block 3 and the low resistance block 4. The wheel frame 1 is installed in the heat dissipation groove 19 and the wheel frame 1 is rotatably connected to the second housing 18. The lower end face of the passive stop block 12 is fixedly connected to the first housing 17. The rigid input cable 6 passes through the front end face of the first housing 17 and is fixedly connected to the first housing 17. The rigid output cable 7 passes through the side end face of the second housing 18 and is fixedly connected to the second housing 18. The external motor switch 14 and the power switch 15 are both installed on the front end face of the first housing 17.

[0026] In use, first, connect the power switch 15 to the power supply, and connect the rigid output conduit 7 to the fabric setting device. Normally, both conductive discs 5 are in contact with the high-resistance block 3 to reduce the voltage when current enters the fabric setting device after passing through the high-resistance block 3, thereby reducing the operating power of the fabric setting device and preventing it from operating at full power. Only the heating platen of the fabric setting device is kept at a relatively low temperature. When the user needs to use the fabric setting device, press the external motor switch 14 to cause the compound gear 10 to rotate forward via the servo motor 11, which in turn causes the upper gear 8 to rotate until the active stop block 1003 touches the internal motor switch 13, thereby activating the servo motor 11. Motor 11 is turned off and stops generating power. Then, the clockwork timer 9 causes the upper gear 8 to rotate slowly and uniformly. The upper gear 8 then causes the compound gear 10 to rotate slowly and uniformly in reverse. Before the active stop block 1003 re-contacts the front end of the passive stop block 12 due to the reversal of the compound gear 10, the blocks in contact with the conductive disk 5 will change from high resistance block 3 to low resistance block 4. This allows the current to enter the fabric setting equipment with a higher voltage after passing through the low resistance block 4, allowing the fabric setting equipment to operate at a higher power. This allows the hot pressing heating plate of the fabric setting equipment to be heated to its maximum temperature. The clockwork timer 9 also limits the time for the high resistance block 3 to re-contact the conductive disk 5, thus realizing the timed switching of the fabric setting equipment from high power operation to low power operation.

[0027] As a supplement, the conductive disk 5 is used to contact the high-resistance block 3 or the low-resistance block 4 and to connect to the rigid input conduit 6 or the rigid output conduit 7 to realize the connection of the circuit. The power switch 15 is used to control the disconnection and connection of the circuit between the fabric shaping equipment and the power supply, while the heat dissipation groove 19 and the annular heat dissipation fins 16 are used to accelerate the heat dissipation of the wheel frame 1, the high-resistance block 3 and the low-resistance block 4.

[0028] Through the above steps, by setting the wheel frame 1, high-resistance block 3, low-resistance block 4, and clockwork timer 9, both conductive discs 5 are in contact with the high-resistance block 3 under normal conditions. This reduces the voltage when current enters the fabric setting equipment after passing through the high-resistance block 3, thereby reducing the operating power of the fabric setting equipment. This prevents the fabric setting equipment from operating at full power, keeping only the hot-pressing heating plate of the fabric setting equipment at a relatively low temperature. When the user needs to use the fabric setting equipment, pressing the external motor switch 14 causes the servo motor 11 to rotate the compound gear 10 forward, which in turn causes the upper gear 8 to rotate until the active stop block 1003 touches the internal motor switch 13. This causes the servo motor 11 to stop and cease exerting force. Subsequently, the clockwork timer 9 causes the upper gear 8 to rotate slowly and uniformly back, and the upper gear 8 then causes the compound gear 10 to rotate slowly and uniformly back, until the active stop block 1003 touches the internal motor switch 13. This causes the servo motor 11 to stop and cease exerting force. Then, the clockwork timer 9 causes the upper gear 8 to rotate slowly and uniformly back, and the upper gear 8 then causes the compound gear 10 to rotate slowly and uniformly back. Before the compound gear 10 re-engages with the front end of the passive stop block 12 due to the reverse rotation, the high-resistance block 3 in contact with the conductive disk 5 will change to the low-resistance block 4. This allows the current to enter the fabric setting equipment with a higher voltage after passing through the low-resistance block 4, enabling the fabric setting equipment to operate at a higher power. This allows the hot-pressing heating plate of the fabric setting equipment to be heated to its maximum temperature. The spring timer 9 limits the time for the high-resistance block 3 to re-engage with the conductive disk 5, thus achieving a timed switch between high-power and low-power operation of the fabric setting equipment. This avoids the equipment operating at high temperature and high power for a long time, reducing the aging rate and probability of damage. It also allows the hot-pressing heating plate of the fabric setting equipment to be heated from a relatively lower temperature to the maximum temperature instead of from the ambient temperature, saving preheating time and improving both efficiency and ease of operation.
