Description

Technical Field

[0001] The present invention relates to the technical field of hot presses, and in particular to an electric intelligent flat hot press. Background Art

[0002] An electric flat hot press can transfer various heat transfer prints onto fabrics such as cotton, linen, and chemical fibers through heat transfer, and can also perform heat treatment processes such as screen printing, plastisol, and foaming. It can also bake color labels, portrait photos, landscape patterns, etc. onto porcelain plates and metal plates, and is particularly suitable for making medals, commemorative badges, cultural shirts, etc., which are economical and practical with exquisite patterns.

[0003] An electric flat hot press consists of a frame, an electric drive system, a heating system, upper and lower pressure plates, a temperature and pressure control system, etc. Among them, the electric drive system generally includes a power source and a transmission mechanism. The power source can use a planetary reduction motor or a turbine reduction motor to provide precise displacement and pressure control. The common transmission mechanism is a ball screw, which converts the rotational motion of the motor into a linear motion; some models may incorporate hydraulic assistance (electro-hydraulic hybrid) to enhance pressure output. For example, Chinese Patent CN202320316710.X discloses an automatic hot press. In this solution, the up-and-down translation drive of the hot press plate assembly is completed by the motor + screw method. However, in actual use, the pressure provided to the hot press plate assembly by this direct drive downward method is not enough, only 20 - 80 kg, which will result in a general hot stamping effect when performing product hot stamping.

[0004] In addition, in the above solution, since structures such as the motor and screw are all installed on the upper support, and the upper support is fixed on one side of the side support. When the overall weight of the upper support is relatively heavy, it will inevitably cause a very large force at the connection between the upper support and the side support, and has relatively high requirements for the material of the outer shell and the stability of the assembly structure. And in actual use, since there is no space provided between the support and the base in the electric flat hot press of the above solution, only the fabric to be hot pressed can be placed above the support. If it is necessary to perform hot pressing on clothes, simply placing the clothes cannot accurately place the clothes in the appropriate position in the first place, and the clothes are also prone to displacement after being placed. Summary of the Invention

[0005] To solve the above problems, the present invention proposes an electric intelligent flat hot press.

[0006] The technical solution adopted by the present invention is: an electric intelligent flat hot press, comprising:

[0007] A base;

[0008] A main beam frame, fixed on the base and having an external beam frame extending outside the base;

[0009] The upper heating plate includes a fixing bracket fixed on the external beam frame. A linkage rod arranged vertically is penetrated through the fixing bracket. A heating plate main body is fixed below the linkage rod. A reset structure is arranged between the linkage rod and the fixing bracket.

[0020] Preferably, the heating plate main body sequentially includes a connecting frame, a first heat insulation frame, a heat preservation layer and a heating plate from top to bottom. The lower end of the linkage rod is fixed on the connecting frame. The lower support plate is in an "I" shape and sequentially includes a support plate main body, a connecting part and a sliding part from top to bottom. Front and rear spaces are respectively arranged on the front and rear sides of the connecting part. The sliding part is slidably installed on the main beam frame in the front-rear direction.

[0021] Preferably, shaft wheels and pressing-down ends are respectively arranged at two ends of the lever. Among them, the shaft wheel abuts above the nut seat, and the pressing-down end abuts above the linkage rod.

[0022] Preferably, the lever driving and pressing device further includes a rotating positioning frame fixed between the two external beam plates, and a guiding opening for the lever to pass through is arranged on the rotating positioning frame.

[0023] Preferably, the reset structure is a reset spring sleeved outside the linkage rod. A limiting piece is fixed on the linkage rod. The reset spring is arranged between the limiting piece and the fixed bracket. In the working state, the pressing-down end drives the linkage rod and the main body of the heating plate to move downward together, and the reset spring is compressed.

[0024] Preferably, a second micro switch is arranged on the mounting bracket. The hot press further includes a standby state. In the standby state, there is a distance between the main body of the heating plate and the lower support plate, and the lower end of the nut seat abuts on the second micro switch.

[0025] Preferably, slide ways are respectively arranged on the left and right sides of the main beam frame. Guide rails are respectively arranged at the left and right ends of the sliding part. The guide rails are slidably connected in the slide ways. A first micro switch is arranged at the front end of the main beam frame. A handle is installed on the outer side of the front end of the sliding part. In the working state, the inner side of the front end of the sliding part abuts on the first micro switch.

[0026] Preferably, an upper cover shell is arranged above the base. An outer cover shell is arranged outside the main beam frame. The outer cover shell at least includes a base plate. The external beam frame and the integrated circuit board are both fixed on the base plate. A flange protruding upward is arranged at a position corresponding to above the shaft rod on the outer cover shell. A display pcb and a control board are installed at the front end of the upper position of the outer cover shell. A display screen is installed on the display pcb. The display screen is obliquely arranged on the outer surface of the outer cover shell. A plurality of control buttons are installed on the control board.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Install a lever driving and pressing device at the rear side of the external beam frame. The driving motor drives the screw rod to rotate, and drives the nut seat installed on the screw rod to move up and down. By skillfully using the lever principle, when one end of the lever is driven by the nut seat to rise, the lever rotates around the shaft rod, and the other end of the lever is driven to press down the linkage rod, thereby greatly increasing the downward pressure on the linkage rod. Since the linkage rod is fixed on the main body of the heating plate, when hot pressing the product, the pressure between the main body of the heating plate and the lower support plate will be large enough, and the hot pressing effect is good.

[0030] 2. The lower support plate is slidably installed on the main beam frame in the front-back direction through a sliding part. The user can pull out the lower support plate forward through the handle to place the product on the lower support plate. Since there is a connecting part between the second heat insulation frame and the sliding part, and there are spaces on both the front and rear sides of the connecting part (the overall shape of the lower support plate is "I" shaped), when the user needs to press and iron clothes, the clothes can be put on the lower support plate, and the fixing effect is good and it is convenient to use.

[0031] 3. Install heavier components such as the motor and the screw rod at the rear side of the external beam frame. The weight of the front part of the external beam frame is reduced, and the weight distribution of the external beam frame and the components installed on it will be more reasonable, and the overall structure of the machine has good stability.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0057] Specific implementation: Refer to Figures 1 - 19 , the present invention is an electric intelligent flat hot press, including:

[0058] Base 1;

[0059] Main beam frame, fixed on the base 1 and having an external beam frame extending outside the base 1;

[0060] Upper heating plate 3, including a fixed bracket 31 fixed on the external beam frame, a linkage rod 33 arranged vertically is penetrated through the fixed bracket 31, a heating plate main body is fixed below the linkage rod 33, and a reset structure is provided between the linkage rod 33 and the fixed bracket 31;

[0061] Lever 47 driving and pressing device 4, at least including a shaft rod 46 installed on the external beam frame, at least one lever 47 rotatably arranged on the shaft rod 46, and a driving source installed at one end of the lever 47 and driving the lever 47 to rotate around the shaft rod 46. The other end of the lever 47 away from the driving source abuts against or is fixed to the upper end of the linkage rod 33;

[0062] Lower support plate 5, installed on the base 1 or the main beam frame. The hot press has a working state, and in the working state, the lower support plate 5 is arranged directly below the heating plate main body;

[0063] Integrated circuit board 7, installed in the base 1 or the main beam frame, and the upper heating plate 3 and the driving source are both electrically connected to the integrated circuit board 7.

[0064] As a preferred implementation manner of this embodiment, please refer to Figures 4 - 8 , it can be seen that the main beam frame includes two main beam plates 2 arranged opposite to each other left and right. The main beam plates 2 have external beam plates extending outside the base 1, and the driving source includes:

[0065] Mounting bracket 41, fixed between the two external beam plates;

[0066] Driving motor 42, installed on the mounting bracket 41;

[0067] Lead screw, arranged vertically and linked to the driving motor 42;

[0068] The upper connecting frame 45 is fixed between two external beam plates and is used to cooperate with the end of the feeding screw rod for rotational installation.

[0069] The nut seat is installed on the screw rod, and one end of the lever 47 abuts against or is installed on the nut seat.

[0070] Next, please refer to Figure 14 、 Figure 18 and Figure 19 . It can be seen that in this embodiment, the heating plate body sequentially includes a connecting frame 32, a first heat insulation frame 35, a heat preservation layer 36, and a heating plate 37 from top to bottom. The lower end of the linkage rod 33 is fixed on the connecting frame 32. The lower support plate is in an "I" shape and sequentially includes a support plate body, a connecting portion 54, and a sliding portion 55 from top to bottom. The support plate body sequentially includes a second heat insulation frame 51, a heat insulation layer 52, and a support panel 53 from bottom to top. Front and rear spaces 56 and 57 are respectively provided on the front and rear sides of the connecting portion 54, and the sliding portion 55 is slidably installed on the main beam frame in the front-rear direction.

[0071] In this embodiment, the heating plate 37 uses a die-cast aluminum double-tube double-control design, two-way temperature probes, and two-way temperature constant components on the main board, making the temperature difference inside and outside the heating plate 37 smaller.

[0072] In addition, please refer to Figure 19 . It can be seen that a plurality of buckles 531 are provided upward on the outer periphery of the support panel 53, and the buckles 531 can be used to cooperate with the high-temperature cloth placed above the support panel 53 for clamping and fixing.

[0073] Here, by respectively providing a front space and a rear space on the front and rear sides of the connecting portion 54, after pulling the lower support plate 5 forward from the main beam frame, the clothes to be heat-pressed can be put on the lower support plate 5, and the fixation is very firm. And because the front space and the rear space are large enough, the clothes can be put on normally or reversely according to needs. When printing clothes, it is not necessary to lay them on the workbench on both sides at the same time, preventing the reverse penetration of colors to the other side of the clothes.

[0074] Please continue to refer to Figure 16 and Figure 17 . It can be seen that in this embodiment, the main beam frame further includes a cross beam frame plate 22 provided between two main beam plates 2. A first micro switch 23 is provided at the front end of the cross beam frame plate 22. In the working state, the inner front end of the sliding portion 55 abuts against the first micro switch 23.

[0075] Here, only when the first micro switch 23 senses that the sliding portion 55 has not been pulled out can the heat-pressing action start, otherwise a prompt will appear on the display screen 81.

[0076] And, please refer to Figure 15 and Figure 16, in this embodiment, slideways 21 are respectively arranged on the left and right sides of the main beam frame, guide rails 551 are respectively arranged at the left and right ends of the sliding part 55, the guide rails 551 are slidably connected in the slideways 21, and a handle is installed on the outer side of the front end of the sliding part 55.

[0077] Here, please refer to Figure 12 and Figure 14 , when it is necessary to pull the lower support disc 5 forward out of the main beam frame, the user can grab the handle and pull the sliding part 55 forward, and the guide rail 551 slides along the slideway 21.

[0078] In addition, in this embodiment, there are two levers 47, which are respectively arranged on the left and right sides of the lead screw. Shaft wheels 471 and pressing ends 472 are respectively arranged at both ends of the lever 47. Among them, the shaft wheel 471 abuts above the nut seat, and the pressing end 472 abuts above the linkage rod 33.

[0079] Next, please refer to Figure 7 and Figure 11 , it can be seen that in this embodiment, the lever 47 driving device 4 further includes a rotating positioning frame 48 fixed between two external beam plates, and a guiding opening 481 for the lever 47 to pass through is arranged on the rotating positioning frame 48.

[0080] In this embodiment, since there are two levers 47, two guiding openings 481 need to be arranged on the rotating positioning frame 48 to respectively position the two levers 47, preventing the left and right position offsets from occurring during the rotation of the two levers 47 around the shaft rod 46, and the rotational stability of the lever 47 rotating around the shaft rod 46 will be better.

[0081] Moreover, in this embodiment, two shaft sleeves 461 are sleeved on the shaft rod 46, and the shaft sleeves 461 are arranged between the external beam plates and the lever 47. The arrangement of the shaft sleeves 461 can cooperate with the rotating positioning frame 48 to further prevent the left and right position offsets of the lever 47 during the rotation process.

[0082] Please refer to Figure 9 , Figure 10 and Figure 18 , it can be seen that in this embodiment, the reset structure is a reset spring 34 sleeved outside the linkage rod 33. A limiting piece 331 is fixed on the linkage rod 33, and the reset spring 34 is arranged between the limiting piece 331 and the fixed bracket 31. In the working state, the pressing end 472 drives the linkage rod 33 and the main body of the heating disc to move downward together, and the reset spring 34 is compressed.

[0083] Working principle of the lever drive device: When it is necessary to press down the upper heating plate 3, the drive motor 42 operates and drives the lead screw to rotate. Since the nut seat is mounted on the lead screw, the nut seat can be driven to rise along the lead screw. During the rising process of the nut seat, since the shaft wheel 471 at one end of the lever 47 abuts above the nut seat, the lever 47 will be driven to rotate counterclockwise around the shaft rod 46. At this time, the pressing end 472 at the other end of the lever 47 will press down the linkage rod 33 and drive the linkage rod 33 to translate downward (in this embodiment, the fixed bracket 31 is provided with a shaft hole 311 for the linkage rod 33 to pass through). During the downward translation of the linkage rod 33, the spring provided between the limit piece 331 and the fixed part will be compressed, and the heating plate main body fixed below the linkage rod 33 will follow the linkage rod 33 to translate downward together until it abuts against the lower support plate 5, and the fabric to be hot-pressed is clamped between the heating plate main body and the lower support plate 5.

[0084] Note that in this embodiment, the lever 47 is a labor-saving lever, that is, the power arm is greater than the resistance arm, which can effectively increase the output torque on the linkage rod 33. With the same drive motor 42, a greater downward pressure can be generated compared with the prior art. After actual testing, in the flat hot press of this embodiment, the pressure between the heating plate main body and the lower support plate 5 can reach 50 - 280 kg, and the hot-pressing effect of the product is very good.

[0085] Then, please refer to Figure 6 , and it can be seen that in this embodiment, the mounting bracket 41 is provided with a second microswitch 49. The hot press also includes a standby state. In the standby state, there is a spacing between the heating plate main body and the lower support plate 5, and the lower end of the nut seat abuts on the second microswitch 49.

[0086] After the hot pressing work is completed, the drive motor 42 operates and drives the lead screw to rotate in the reverse direction. Similarly, at this time, the nut seat descends, and the downward pressure of the pressing end 472 of the lever 47 on the linkage rod 33 gradually decreases. The return spring 34 gradually restores its deformation and drives the heating plate main body to rise. When the lower end of the nut seat abuts on the second microswitch 49, the second microswitch 49 sends a signal to the integrated circuit board 7, and the integrated circuit board 7 controls the drive motor 42 to stop operating.

[0087] Please refer to Figures 1 - 5It can be seen that in this embodiment, the base 1 includes a bottom plate and an upper cover shell 13 fixed above the bottom plate (the setting of the upper cover shell 13 will not affect the forward and backward sliding of the sliding part 55), an outer cover shell 6 is provided on the outside of the main beam frame, and the outer cover shell 6 at least includes a substrate 61, and the external beam frame and the integrated circuit board 7 are fixed on the substrate 61. The outer cover shell 6 is provided with an upwardly protruding flange 62 corresponding to the position above the shaft rod 46, and a display PCB 8 and a control board 9 are installed at the front end of the upper position of the outer cover shell 6. A display screen 81 is installed on the display PCB 8, and the display screen 81 is arranged obliquely on the outer surface of the outer cover shell 6. A plurality of control buttons 91 are installed on the control board 9, and the control buttons 91 extend to the outer surface of the outer cover shell 6.

[0088] In this embodiment, the control button 91 can be made of silicone material, which has a better hand feel, and the control button 91 includes a power button, a temperature button, a time button, a start button, an increase button and a decrease button, etc., which can be adjusted according to actual conditions. The silicone button + touch button design has a reasonable layout, a humanized program design, and a simpler user operation.

[0089] In addition, in this embodiment, the pressure is adjustable in four levels: 80, 120, 160, and 280KG. Under the maximum pressure, the color fastness and color uniformity of the hot-pressed products can be significantly improved.

[0090] Furthermore, in this embodiment, the display screen 81 may choose to use a touch screen, so that the functions of some setting buttons can be transferred to the display screen 81 for operation, and the control buttons 91 will be more concise.

[0091] Note: See Figure 1 It can be seen that in this embodiment, the display screen 81 is fixed on the outer cover shell 6 and is placed at an angle of 60 degrees, which makes it more convenient for the user to observe the data on the display screen 81.

[0092] In this embodiment, a connecting plate 24 is fixed below the two main beams, and the connecting plate 24 is fixed to the bottom plate of the base 1 , thereby fixing the main beams to the base 1 .

[0093] More specifically, the left and right sides of the lower end of the base 1 are provided with a make way recess 11, the lower end of the base 1 is provided with a plurality of bottom pads 12, an upper cover shell 38 is installed above the first heat insulation frame 35, an external sleeve 381 is installed on the upper cover shell 38, an internal sleeve 63 is installed on the base plate 61, the external sleeve 381 is sleeved on the outer periphery of the internal sleeve 63, the linkage rod 33 is arranged on the inner periphery of the internal sleeve 63, and a power supply accessory 10 is provided at the lower rear end of the outer cover shell 6, and an electrical socket and a main power switch 101 are provided on the power supply accessory 10.

[0094] Here, the setting of the inner sleeve 63 and the outer sleeve 381 is mainly used to cover the internal structure, which will make it more beautiful.
