Description

Technical Field

[0001] This utility model relates to heat press machines, specifically to a dual-station heat press machine. Background Technology

[0002] In existing heat press machine technology, a rigid pressing and feeding platform is commonly used to flatten the object being pressed. Traditional heat press machines use at least one motor as their power source. The motor drives a transmission assembly, which in turn connects to a lifting mechanism, which in turn drives the pressing plate. This rigid connection of the entire drive system easily leads to deformation of parts, thus reducing the lifespan of the transmission components.

[0003] Existing heat press machine technology lacks an automatic alignment function, which can easily cause the pressure plate to shift off the feeding platform during the switching between two workstations, resulting in poor heat press quality and increased defect rate.

[0004] In addition, the existing heat press machine's heat plate section lacks an effective orientation mechanism during movement, and is prone to deviation when swinging horizontally, further affecting the accuracy and quality of the heat pressing.

[0005] In view of this, there is an urgent need for a new type of heat press machine that can solve the above problems. Utility Model Content

[0022] Furthermore, the linkage orientation mechanism includes:

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0044] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0045] Example 1: The specific structure of this utility model is as follows:

[0046] Please refer to the appendix. Figure 1-8 This utility model discloses a dual-station heat press machine, including a frame 1 and two sets of feeding platforms 5 disposed on the upper surface of the frame 1 and spaced apart by a certain distance. The two sets of feeding platforms 5 form a dual-station structure. The heat press machine also includes:

[0047] A reciprocating drive mechanism 4 is provided on the frame 1. The power source of the reciprocating drive mechanism 4 is a first cylinder 48. The tail end of the first cylinder 48 is rotatably connected to the frame 1. The reciprocating drive mechanism also includes a swing arm mechanism that is driven and connected to the drive shaft of the first cylinder 48.

[0048] The hot plate part 7 is driven and connected to the reciprocating drive mechanism 4 and can be driven by the reciprocating drive mechanism 4 to perform reciprocating motion in a dual-station manner. The hot plate part 7 has a lifting mechanism and a hot plate 2 driven and connected to the lifting mechanism. The power source of the lifting mechanism is a second cylinder 71.

[0049] The swing arm mechanism includes:

[0050] Vertical rod 47 is vertically and rotatably connected to the end of the drive shaft of the power source;

[0051] A rotating spindle 43 is rotatably mounted on the frame 1. The rotating spindle is a tubular structure. Inside the rotating spindle 43 is a vertical shaft fixed to the frame 1. The upper and lower sides of the vertical shaft are connected to the rotating spindle 43 through a spherical bearing 400.

[0052] Angle plate 45 is sleeved and fixed to the circumferential surface of the rotating spindle 43, and limit stops are provided on both sides of it; it is used to cooperate with the angle limiting structure to limit the rotation angle of the rotating spindle 43.

[0053] The first end of the swing arm 49 is vertically fixed to the upper end of the rotating main shaft 43 and moves synchronously with the rotating main shaft 43. The hot plate part 7 is rotatably mounted on the second end of the swing arm 49.

[0054] The transmission system between the heating plate part 7 and the reciprocating drive mechanism 4 is also provided with a linkage orientation mechanism that maintains the orientation of the lifting mechanism and the orientation of the heating plate 2 during horizontal swing.

[0055] The heating plate part 7 is also provided with an automatic alignment structure, which includes a radial joint bearing 76 provided on the heating plate part 7. The radial joint bearing 76 is located between the movable end of the lifting mechanism and the support seat assembly 75 at the end of the reciprocating drive mechanism 4.

[0056] The lifting mechanism also includes a lifting plate 710, which is connected to the lower end of the piston rod of the second cylinder 71. The lifting plate 710 is connected to the hot plate 2 through multiple sets of elastic pressing components.

[0057] The radial spherical bearing 76, the spherical bearing 400, and the multiple sets of elastic clamping components constitute a structure capable of eliminating elastic deformation caused during the use of the dual-station heat press machine. The radial spherical bearing 76 enables the lifting plate 710 to rotate at multiple angles relative to the support base assembly 75, thereby driving the heat press plate 2 to automatically adjust its position, ensuring that the heat press plate 2 is precisely aligned with the feeding platform 5, and realizing the automatic alignment function.

[0058] The reciprocating drive mechanism also includes an angle limiting structure that restricts the rotation angle of the swing arm mechanism. This angle limiting structure includes two sets of limiting components, which are fixed to the frame 1 and located on both sides of the rotating spindle 43. The rotation path of the limiting stop can reach the corresponding limiting component. When the rotating spindle 43 drives the angle plate 45 to rotate, the limiting stop will rotate with the angle plate 45. When the limiting stop contacts the adjusting rod 44, the rotating spindle 43 stops rotating, achieving precise positioning of the workstation. The hydraulic buffer 46 can apply a buffering force to the limiting stop when it approaches the adjusting rod 44, avoiding rigid collision between the limiting stop and the adjusting rod 44.

[0059] The limiting assembly includes a limiting bracket, a hydraulic buffer 46, and an adjusting rod 44, with the limiting bracket fixed inside the frame 1.

[0060] The hydraulic damper 46 and the adjusting rod 44 are mounted side by side and vertically on the limiting bracket, and both the hydraulic damper 46 and the adjusting rod 44 are on the rotation path of the limiting stop.

[0061] The linkage orientation mechanism includes:

[0062] The directional flange 42 is fixedly installed at the upper end of the vertical shaft, and its two ends extend outward to form cantilever.

[0063] Two equal-length connecting rods 41 are rotatably connected to the two cantilevered ends of the directional flange 42, one-to-one. The outer ends of the two equal-length connecting rods 41 are rotatably connected to the heating plate part 7. The two equal-length connecting rods 41 remain parallel during movement. When the reciprocating drive mechanism 4 drives the heating plate part 7 to swing between the two workstations, the two equal-length connecting rods 41 remain parallel, forming a parallelogram connecting rod structure, which restricts the rotation of the support base assembly 75 and ensures that the heating plate part 7 will not deflect during horizontal swing, thereby maintaining the orientation of the lifting mechanism and the heating plate 2.

[0064] The elastic clamping assembly includes:

[0065] A plug bolt 77 is movably connected at one end to the lifting plate 710, and the lower end of the plug bolt 77 is fixed to the heating plate 2;

[0066] A compression spring 78 is sleeved on the rod of the plug bolt 77. One end of the compression spring 78 abuts against the lifting plate 710, and the other end abuts against the hot plate 2.

[0067] The heating plate 2 is equipped with a heating element 21, which is connected to an external temperature control system via wires. The temperature control system can adjust the heating temperature of the heating element 21 as needed to ensure a stable surface temperature of the heating plate 2. During the heating process, the second cylinder 71 pushes the lifting plate 710 down. The lifting plate 710 transmits pressure to the heating plate 2 through a compression spring 78. The elastic deformation of the compression spring 78 can absorb impact and compensate for the elastic deformation of the parts, ensuring that the pressure of the heating plate 2 on the workpiece is uniform.

[0068] The heating plate 2 is covered by a protective cover 8, which covers the upper surface and peripheral sides of the heating plate 2 with a gap between the protective cover 8 and the heating plate 2. Preferably, the protective cover 8 is designed with a hollow structure. The protective cover 8 allows the operator to easily observe the working status of the heating plate 2 and prevents burns to the operator.

[0069] Example 2:

[0070] The following is the working process of this dual-station heat press machine:

[0071] 1. Preparation: Place the two objects to be heat-pressed onto the two sets of feeding platforms 5 respectively. Set the heating temperature of the heating tube 21 through the external control system. After the temperature of the heat-pressing plate 2 reaches the set value, start the equipment.

[0072] II. Heat Transfer at the First Station: The first cylinder 48 in the reciprocating drive mechanism 4 drives the vertical rod 47 to move. The vertical rod 47 drives the rotating spindle 43 to rotate. The rotating spindle 43 drives the swing arm 49 and the heat transfer plate 7 to swing above the first set of feeding platforms 5. At this time, one side of the limiting stop on the corner plate 45 contacts the corresponding side adjusting rod 44, the rotating spindle 43 stops rotating, and the heat transfer plate 7 is precisely positioned above the first station. Subsequently, the second cylinder 71 in the lifting mechanism drives the piston rod to extend downward, causing the lifting plate 710 and the heat transfer plate 2 to descend. The heat transfer plate 2 contacts the workpiece at the first station and applies pressure. The heat generated by the heating tube 21 is transferred to the workpiece through the heat transfer plate 2, completing the heat transfer operation at the first station.

[0073] III. Station Switching: After the heat transfer printing at the first station is completed, the second cylinder 71 drives the piston rod to retract upwards, causing the heat transfer plate 2 to rise and reset. Next, the first cylinder 48 drives the vertical rod 47 to move in the opposite direction, causing the rotating spindle 43 to rotate in the opposite direction. The swing arm 49 and the heat transfer plate 7 then swing to above the second set of feeding platforms 5. At this time, the limiting stop on the other side of the corner plate 45 contacts the adjusting rod 44 on the corresponding side, the rotating spindle 43 stops rotating, and the heat transfer plate 7 is precisely positioned above the second station. During the swinging process of the heat transfer plate 7, the two equal-length connecting rods 41 in the linkage orientation mechanism remain parallel, ensuring that the heat transfer plate 2 does not deflect; the radial joint bearing 76 in the automatic alignment structure automatically adjusts the position of the heat transfer plate 2, ensuring that the heat transfer plate 2 is precisely aligned with the feeding platform 5 of the second station.

[0074] IV. Second Station Heat Transfer: The second cylinder 71 drives the piston rod to extend downwards, causing the heat transfer plate 2 to descend and perform heat transfer on the object being processed at the second station. At the same time, the operator can remove the object that has been heat transferred at the first station and place a new object to be heat transferred, preparing for the next round of heat transfer.

[0075] V. Cyclic Operation: Repeat the above workstation switching and heat transfer process to achieve continuous and efficient operation of the dual workstations.

[0076] This utility model heat press machine features a self-aligning structure. Through the use of radial joint bearings, multiple joint bearings, and multiple sets of elastic clamping components, it solves the problem of existing heat press machines being unable to eliminate elastic deformation. This significantly improves the heat pressing effect and avoids damage to the object being pressed due to excessive machine rigidity.

[0077] This utility model heat press machine is oriented: the parallel arrangement of two equal-length connecting rods in the linkage orientation mechanism ensures that the lifting mechanism and the heat press remain oriented during the horizontal swing of the heat press section, effectively avoiding the offset of the heat press during the movement and improving the accuracy and quality of the heat pressing.

[0078] This utility model heat press machine adopts a dual-station high-efficiency operation: the dual-station structure formed by two sets of feeding platforms enables the heat press machine to simultaneously heat the objects to be pressed at two stations, improving work efficiency and reducing equipment downtime.

[0079] This utility model heat press machine is safe and reliable: the hydraulic buffer and adjusting rod in the angle limiting structure can limit the rotation angle of the swing arm mechanism, prevent it from rotating excessively, protect the equipment, and improve the safety and reliability of the equipment operation.
