Description

Technical Field

[0001] This application relates to the technical field of hot pressing apparatus, and in particular to a hot pressing apparatus. Background Technology

[0002] Fabric hot presses play a vital role in modern industrial production, particularly in garment processing, heat transfer printing, and rhinestone printing. With the continuous changes and diversification of market demands, the development of fabric hot presses has also made significant progress. They not only improve production efficiency but also enhance product quality, meeting the fabric processing requirements of various processes. Whether for large-scale production or small-scale customization, fabric hot presses play an indispensable role, driving the development of related industries.

[0003] In the existing field of semi-automatic fabric hot press machines, to achieve processes such as hot pressing, bonding, and shaping of garment fabrics, a press head that can move up and down vertically is typically used to complete the pressing operation. For areas in garments connected with adhesive strips, the hot press head is generally used first for direct hot pressing, causing the adhesive strip to initially melt and achieve bonding. Subsequent processes, such as ensuring full penetration of the adhesive strip while avoiding indentations, often require manual intervention by an operator. This involves placing a partition between the hot press head and the garment and applying pressure again. This method is more common in small workshops and customized production because of its lower equipment cost, relatively flexible operation, and adaptability to certain production needs.

[0004] However, during the second partition pressing process, operators need to hold the partition with one hand to maintain stability while using the other hand to adjust and support the garment. This makes it impossible for them to use both hands to stretch and flatten the garment in the processing area. As a result, the fabric is very prone to wrinkles, twisting, or displacement during the pressing process. Moreover, once these wrinkles are fixed during the adhesive tape curing process, they will remain permanently on the surface of the garment, thus affecting the appearance quality and yield of the product. Summary of the Invention

[0005] In order to improve product quality, this application provides a hot pressing device.

[0006] This application provides a hot pressing device, which adopts the following technical solution: A hot pressing device includes a worktable, on which a hot pressing base is provided; A fixed column is provided on the workbench, and a support base is provided on the fixed column; The upper hot press block is disposed on the support base and located directly above the lower hot press base. The support base is provided with a driving component that drives the upper hot press block to slide up and down. The worktable is provided with a control component that controls the start of the driving component. A support frame is mounted on the workbench; A heat insulation strip is installed on the support frame, and the heat insulation strip passes between the upper hot-pressing block and the lower hot-pressing seat; The control shaft is rotatably connected between the support base and the worktable; A support plate is mounted on the control shaft; A heat insulation board is slidably mounted on the support plate, and the support plate is provided with an elastic support component to support the heat insulation board; The workbench is provided with a hot pressing area and a waiting pressing area. The hot pressing base is located in the hot pressing area. The hot pressing area and the waiting pressing area are spaced apart. The hot pressing area and the waiting pressing area are spaced apart circumferentially with the control axis as the center. A drive gear that rotates within the support is provided on the outer periphery of the control shaft, and a drive rack that meshes with the drive gear is slidably provided within the support. A power assembly is mounted on the support base. When the upper hot-press block moves upward away from the lower hot-press base, the power assembly drives the drive rack to slide. When the upper hot-press block slides upward twice in succession, the sliding direction of the drive rack is opposite.

[0007] By adopting the above technical solution, the workbench is equipped with a hot pressing base, a fixed column, and a support frame. A support seat is installed on the fixed column, and the support seat is equipped with a driving component that drives the hot pressing block to slide up and down and a control component that controls its start-up, which can realize the hot pressing operation of clothing fabric. The heat insulation tape passes between the hot pressing block and the hot pressing base to provide heat insulation. The control shaft is rotatably connected between the support seat and the workbench, and a bearing plate is installed on the control shaft. The heat insulation plate slides up and down on the bearing plate and is supported by an elastic support component, which can assist in the hot pressing of the fabric. The hot pressing area and the waiting area are arranged alternately on the workbench, circumferentially distributed with the control shaft as the center, which makes it easy to distinguish different processing states. The drive gear on the outer periphery of the control shaft meshes with the drive rack that slides inside the support seat. The power component drives the drive rack to slide when the hot pressing block moves upward away from the hot pressing base, and the two sliding directions are opposite, which can realize automatic control of different actions, improve the efficiency and quality of hot pressing, reduce the impact of manual operation on the fabric causing wrinkles, twists or displacement, and improve the product appearance quality and yield.

[0008] Optionally, the power assembly includes a power gear block, a power bar, a power gear, a reciprocating lead screw, and a power block; The power bar is located on the top of the hot press block. The power bar slides up and down on the support base. Multiple receiving grooves are evenly spaced on the vertical side wall of the power bar. The power bar is provided with a hinge shaft located at the bottom of the receiving groove. The power tooth block is rotatably connected to the hinge shaft. The reciprocating lead screw is rotatably connected to the support base, and the power gear is disposed on the outer periphery of the reciprocating lead screw. When the power bar slides upward, the power tooth block meshes with the power gear. When the power bar slides downward, the power tooth block flips upward, and at this time the power tooth block slides past the power gear. The power block is disposed on the top of the drive rack, and the power block is threadedly connected to the reciprocating lead screw.

[0009] By adopting the above technical solution, the power component can drive the drive rack to slide by sliding the hot pressing block up and down. It can also achieve that the drive rack slides in opposite directions when the hot pressing block slides up twice in succession, automatically completing the position switching of relevant components during the hot pressing process without manual operation to adjust. This improves the efficiency and automation of hot pressing operations and reduces errors and instability caused by manual intervention.

[0010] Optionally, the top of the drive rack is provided with a groove for the power block to slide, and the drive rack is provided with an elastic connector located in the groove. The elastic connectors are symmetrically arranged and located on both sides of the power block. The support base is slidably connected to a plug-in post perpendicular to the drive rack. The drive rack has a plug-in groove on the side away from the drive rack. The support base is provided with an elastic power member that drives the plug-in post to insert into the plug-in groove when the plug-in post is aligned with the plug-in groove. The support base is equipped with a transmission component. When the hot-pressing upper block slides downward, the transmission component drives the insertion post to disengage from the insertion slot.

[0011] By adopting the above technical solution, the power block can be made to slide stably by using the elastic connector. The position of the drive rack can be locked by the cooperation of the elastic power component and the plug-in column. When the hot pressing block slides down, the transmission component can make the plug-in column disengage from the plug-in slot, thereby realizing flexible control of the movement state of the drive rack, ensuring the stability and reliability of the hot pressing device, and improving the efficiency of hot pressing operation.

[0012] Optionally, the transmission assembly includes a transmission block and a transmission rope; The support base is provided with a bearing block at its bottom, the transmission block slides on the bearing block, and the end of the bearing block is provided with an arc surface structure; The transmission rope slides through the bearing block and the support base. One end of the transmission rope is connected to the side wall of the transmission block, and the other end of the transmission rope is connected to the plug-in post on the side away from the drive rack.

[0013] By adopting the above technical solution, the transmission block slides on the support block and is connected by the transmission rope, so that the insertion post can be driven to disengage from the insertion slot when the hot pressing block slides down. The arc-shaped structure at the end of the support block helps the transmission block slide smoothly, ensuring the operational stability of the device.

[0014] Optionally, the elastic power component is a power spring, which is sleeved on the outer periphery of the transmission rope. One end of the power spring abuts against the side of the insertion post away from the drive rack, and the other end abuts against the support seat.

[0015] By adopting the above technical solution, the power spring provides elastic driving force to the plug, so that the plug can be reliably inserted when it is aligned with the plug slot. It is also sleeved on the outer periphery of the transmission rope, which ensures stable force transmission, makes the plugging action more precise, and facilitates the transmission component to control the plug to disengage from the plug slot.

[0016] Optionally, the elastic connector is a connecting spring, one end of which is fixed to the groove wall on the side of the slide away from the power block, and the connecting spring and the power block abut against each other.

[0017] By adopting the above technical solution, the connecting spring can buffer and reset the power block, ensuring that the power block slides stably in the slide groove, thereby ensuring the smooth movement of the drive rack, making the motion coordination of each component of the hot pressing device better, and ensuring the normal operation of the hot pressing work.

[0018] Optionally, the elastic support assembly includes a support column and a support tension spring; The bottom of the support plate is provided with a connecting groove for the heat insulation plate to slide up and down. There are multiple support columns, which are respectively arranged on the top of the heat insulation plate. The support columns slide up and down on the support plate. The support spring is disposed in the connecting groove, with one end of the support spring fixed to the top of the heat insulation plate and the other end fixed to the top wall of the connecting groove.

[0019] By adopting the above technical solution, the heat insulation plate can be stably slid up and down on the bearing plate using the support column. The support spring can provide elastic support force, ensuring that the heat insulation plate can flexibly adapt to pressure changes during the hot pressing process, reducing damage caused by rigid contact, and at the same time helping the heat insulation plate to reset, thereby improving the reliability and service life of the hot pressing device.

[0020] Optionally, the driving component is a driving hydraulic cylinder, which is disposed on the top of the support base and drives the hot-pressed upper block to slide up and down.

[0021] By adopting the above technical solution and using the method of setting the driving hydraulic cylinder on the top of the support base, the hot pressing block can be effectively driven to slide up and down, thereby meeting the needs of the hot pressing device to press the garment fabric.

[0022] Optionally, the control element is a control pedal, which is electrically connected to the drive hydraulic cylinder.

[0023] By adopting the above technical solution, and using a control pedal electrically connected to the drive hydraulic cylinder, the operator can conveniently control the start of the drive hydraulic cylinder by stepping on the control pedal, thereby controlling the up and down sliding of the hot pressing block, and realizing convenient operation of the hot pressing device.

[0024] In summary, this application includes at least one of the following beneficial effects: 1. The installation of heat insulation tape and heat insulation board can replace manual hand-held partition, reducing the possibility that operators cannot stretch and flatten the garment with both hands due to holding the partition with one hand. It can reduce wrinkles, twists or displacement of fabric during the pressure process, and improve product appearance quality and yield. 2. The hot pressing zone and the waiting pressing zone are set separately, which can realize the partitioning of hot pressing operations at different stages and improve production efficiency.

[0027] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0028] This application discloses a hot pressing device. Example

[0029] See Figure 1 This application mainly uses a hot pressing device to automatically switch the hot pressing zone 15 and the waiting zone 16, as well as the heat insulation zone 171 and the heat insulation board 3 to assist in hot pressing. This reduces the possibility of fabric wrinkling caused by manual handling of the partition and improves product quality and yield. The following is a further detailed description of this application.

[0030] See Figure 1 and Figure 2 The hot pressing device provided in this application includes a worktable 1, a fixed column 12, a hot pressing block 14, a support frame 17, a heat insulation strip 171, a control shaft 18, a bearing plate 2, a heat insulation plate 3, and a power assembly.

[0031] See Figure 1 and Figure 3The workbench 1 provides the basic platform for the entire hot pressing operation. The fixed column 12 is fixed to the workbench 1, providing support for the support base 13, ensuring that the upper hot pressing block 14 is stably positioned directly above the lower hot pressing base 11, facilitating hot pressing operation. The upper hot pressing block 14 can slide up and down under the action of the driving component, cooperating with the lower hot pressing base 11 to complete the hot pressing process. The insulating tape 171 is installed on the support frame 17, passing between the upper hot pressing block 14 and the lower hot pressing base 11, serving to isolate heat and provide protection. The control shaft 18 is rotatably connected between the support base 13 and the workbench 1. The bearing plate 2 is installed on the control shaft 18, and the heat insulation plate 3 is slidably installed on the bearing plate 2. The elastic support assembly 4 supports the heat insulation plate 3, ensuring that the heat insulation plate 3 is in the appropriate position. The power unit can drive the control shaft 18 to rotate when the upper hot pressing block 14 moves upward away from the lower hot pressing seat 11, thereby switching the hot pressing zone 15 and the waiting pressing zone 16. This cooperative relationship enables the hot pressing device to work efficiently and stably, reducing the problem of fabric wrinkling caused by manual hand operation of the partition, and improving the appearance quality and yield of the product.

[0032] Specifically, the worktable 1 is a flat platform, usually made of metal materials such as steel plates, which have good strength and stability. Of course, high-strength plastic materials can also be used, as long as they can meet the pressure requirements during the hot pressing process. The worktable 1 is provided with a hot pressing zone 15 and a waiting pressing zone 16. The hot pressing zone 15 and the waiting pressing zone 16 are arranged circumferentially with the control shaft 18 as the center. The hot pressing base 11 is located within the hot pressing zone 15, providing support for the hot pressing of the fabric.

[0033] The fixing column 12 is also made of metal, such as stainless steel. One end of the fixing column 12 is fixed to the worktable 1, and the other end is fixedly installed with a support base 13. The support base 13 provides installation space and support for the hot press block 14 and related drive components. The overall structure is stable and can withstand the force during the hot pressing process. High-strength alloy materials can also be used to reduce weight while ensuring strength.

[0034] The upper hot press block 14 is mounted on the support base 13 and located directly above the lower hot press base 11. A driving component provides power for the up-and-down sliding of the upper hot press block 14. The driving component can be a hydraulic cylinder 5, which is fixedly mounted on the top of the support base 13. The piston rod extends and retracts due to changes in hydraulic oil pressure, thereby causing the upper hot press block 14 to slide up and down. Alternatively, an electric push rod can be used, which converts the rotation of a motor into linear motion, similarly enabling the movement of the upper hot press block 14. The worktable 1 is equipped with a control pedal 6, which is placed on the ground and electrically connected to the hydraulic cylinder 5. The operator can activate the hydraulic cylinder 5 by stepping on the control pedal 6, controlling the up-and-down movement of the upper hot press block 14. This method is simple, convenient, and easy to operate.

[0035] The support frame 17 is installed and fixed on the workbench 1 to support the heat insulation tape 171. The heat insulation tape 171 is usually made of cloth tape. During the hot pressing process, the heat insulation tape 171 passes between the upper hot pressing block 14 and the lower hot pressing seat 11, which can effectively transfer heat while avoiding direct contact between the upper hot pressing block 14 and the fabric.

[0036] See Figure 4 and Figure 5 The control shaft 18 is rotatably connected between the support base 13 and the worktable 1. A drive gear 181 is fixedly connected to the outer periphery of the top of the control shaft 18, and the drive gear 181 rotates within the support base 13. The control shaft 18 can be a solid or hollow metal shaft, such as a carbon steel shaft, which has high strength and wear resistance. An aluminum alloy shaft can also be used to reduce weight.

[0037] See Figure 3 and Figure 4 The support plate 2 is fixedly connected to the control shaft 18 and rotates with the rotation of the control shaft 18. A through hole extending vertically is provided on the support plate 2, allowing the upper hot-press block 14 to pass through when the support plate 2 is directly above the lower hot-press seat 11. A connecting groove 21 is provided at the bottom of the support plate 2, surrounding and communicating with the through hole, allowing the heat insulation plate 3 to slide up and down within the connecting groove 21. The elastic support assembly 4 includes support columns 41 and support springs 42. Multiple support columns 41 are respectively disposed on the top of the heat insulation plate 3, and the support columns 41 slide up and down on the support plate 2. The support springs 42 are disposed within the connecting grooves 21, with one end fixedly connected to the top of the heat insulation plate 3 and the other end fixedly connected to the top wall of the connecting groove 21. When the hot pressing upper block 14 passes through the through hole, the hot pressing upper block 14 drives the heat insulation plate 3 to cooperate with the hot pressing lower seat 11 to hot press the fabric. At this time, the heat insulation plate 3 pulls the support spring 42, so that the support spring 42 enters the elastic tension state until the hot pressing upper block 14 moves upward, and the support spring 42 pulls the heat insulation plate 3 to reset.

[0038] See Figure 6 and Figure 7 The power assembly includes a power gear block 71, a power bar 72, a power gear 73, a reciprocating lead screw 74, and a power block 7 (power block 7 is in...). Figure 5 (Winning bid).

[0039] See Figure 7 and Figure 8 The power strip 72 is fixedly connected to the hot press block 14 (the hot press block 14 is in Figure 6At the top (marked), the power bar 72 slides on the support base 13, and slides up and down together with the hot-pressing block 14. Multiple receiving grooves 721 are evenly spaced on the vertical sidewall of the power bar 72. The power bar 72 is fixedly connected to a hinge shaft 722 located within the receiving groove 721 and near the bottom. The power gear block 71 is rotatably connected to the hinge shaft 722. Initially, the power gear block 71 abuts against the bottom wall of the receiving groove 721 under gravity. The reciprocating screw 74 is rotatably connected to the support base 13, and the power gear 73 is fixedly connected to the outer periphery of the reciprocating screw 74, and is also rotatably connected to the support base 13. When the power bar 72 slides upward, the power gear block 71 meshes with the power gear 73, driving the reciprocating screw 74 to rotate; when the power bar 72 slides downward, the power gear block 71 flips upward and abuts against the top wall of the receiving groove 721, at which point the power gear block 71 slides past the power gear 73. The top of the drive rack 19 has an inverted "T"-shaped groove 191 extending along the sliding square groove of the drive rack 19. The power block 7 is disposed on the top of the drive rack 19 and slides within the groove 191. The power block 7 is threadedly connected to the reciprocating lead screw 74. The drive rack 19 is provided with elastic connecting members located within the groove 191. The elastic connecting members are symmetrically arranged on both sides of the power block 7. The elastic connecting members are connecting springs 192. One end of the connecting spring 192 is fixed to the groove wall of the groove 191 away from the power block 7, and the connecting spring 192 abuts against the power block 7. The connecting spring 192 plays a buffering and limiting role, so that when the drive rack 19 is in the limited state, the power block 7 can slide within the groove 191. At this time, the connecting spring 192 on the front side of the power block 7 is in an elastically compressed state. When the reciprocating lead screw 74 rotates, it drives the power block 7 to slide in the slide groove 191, and the power block 7 drives the drive rack 19 to slide through the connecting spring 192 on the front side of the slide, so that the drive gear 181 enters the rotation state.

[0040] See Figure 5 and Figure 6A plug-in post 131 perpendicular to the drive rack 19 is slidably connected within the support base 13. A plug-in groove 193 is formed on the side of the drive rack 19 away from the drive gear 181. An elastic power element is provided within the support base 13. When the plug-in post 131 is aligned with the plug-in groove 193, the elastic power element drives the plug-in post 131 to insert into the plug-in groove 193, thus locking the position of the drive rack 19. The support base 13 is equipped with a transmission assembly 8, which includes a transmission block 81 and a transmission rope 82. A bearing block 133 is fixedly connected to the bottom of the support base 13. The transmission block 81 slides horizontally on the bearing block 133. The end of the bearing block 133 has an arc-shaped structure located outside the bearing block 133. The transmission rope 82 slides through the bearing block 133 and the support base 13. One end of the transmission rope 82 is connected to the side wall of the transmission block 81, and the other end is connected to the side of the plug-in post 131 away from the drive rack 19. When the hot-pressing upper block 14 slides downward, it slides on the arc-shaped structure, pressing the transmission block 81 into the bearing block 133. At this time, the transmission block 81 pulls the transmission rope 82, causing the insertion post 131 to disengage from the insertion slot 193, so that the drive rack 19 can enter the sliding state. The elastic power component is a power spring 132, which is sleeved on the outer periphery of the transmission rope 82. One end of the power spring 132 abuts against the side of the insertion post 131 away from the drive rack 19, and the other end abuts against the support seat 13.

[0041] The implementation principle of a hot pressing device in this application embodiment is as follows: Initially, the heat insulation plate 3 is located in the hot pressing zone 15, and the power block 7 presses the connecting spring 192 on the side away from the power bar 72. When the upper hot pressing block 14 moves downward, it presses the transmission block 81 into the bearing block 133 as it passes the transmission block 81. At this time, the transmission rope 82 pulls the insertion post 131 out of the insertion slot 193, and the connecting spring 192 on the side away from the power bar 72 is released elastically, pushing the drive rack 19 to slide, so that the drive gear 181 drives the control shaft 18 to rotate, driving the heat insulation plate 3 from the hot pressing zone 15 to the waiting pressing zone 16. Then, the upper hot pressing block 14 cooperates with the lower hot pressing seat 11 to perform the first hot pressing on the fabric. After the first hot pressing is completed, the upper hot pressing block 14 moves upward. At this time, the power bar 72 moves upward. Before the power bar 71 contacts the power gear 73, the upper hot pressing block 14 passes the transmission block 81 first. Then the power gear 71 contacts the power gear 73, causing the power gear 71 to drive the power gear 73 to rotate. At this time, the reciprocating screw 74 drives the power block 7 to move from the side near the drive gear 181 to the side near the power gear 73. The power block 7 slides and squeezes the connecting spring 192 near the power bar 72 until the hot pressing upper block 14 squeezes the fabric for the second time. When the hot pressing upper block 14 moves downward again, it squeezes the transmission block 81, causing the bearing plate 2 to move to the hot pressing area 15. Then the hot pressing upper block 14 passes through the through hole and drives the heat insulation plate 3 to move downward, cooperating with the hot pressing lower seat 11 to squeeze the fabric again.

[0042] This hot-pressing device, through its rational structural design and coordinated operation of various components, achieves automation and high efficiency in the hot-pressing process. It reduces fabric wrinkling caused by manual operation of the partitions, improving product appearance quality and yield. The power unit automatically drives the control shaft 18 to rotate based on the up-and-down sliding of the upper hot-pressing block 14, switching between the hot-pressing zone 15 and the waiting-to-press zone 16, reducing manual intervention and improving production efficiency. The elastic support component 4 and elastic connectors ensure the stable operation of the heat insulation plate 3 and the power block 7, extending the equipment's service life.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
