Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic air curtain type inflatable plate presses, in particular to an automatic air curtain type inflatable plate press. Background Art
[0002] The automatic air curtain inflatable plate press is a high-end precision pressure equipment used in printing, packaging, and paper processing. It is mainly composed of an operating table, a drive motor, a placement plate, a hydraulic cylinder, and an air curtain inflatable plate.
[0003] When the automatic air curtain inflatable plate press of the existing technology processes paper products, two pieces of paper are first placed on the placement plate, and then the driving motor drives the placement plate to rotate, aiming to accurately position the paper directly under the inflatable plate. Then the hydraulic cylinder drives the inflatable plate downward to apply uniform pressure on the paper with its flexible surface. However, the positioning accuracy of the placement plate depends on the driving motor. If the motor itself is not accurate enough or wears out due to long-term operation, it will directly lead to deviations in the rotation positioning of the placement plate. This deviation will cause the paper to be unable to be accurately placed in the preset processing position (directly under the inflatable plate), and the pressure applied by the inflatable plate will not be able to act evenly and accurately on the target area of the paper, which will ultimately seriously affect the accuracy and consistency of processing effects such as lamination and hot stamping, and reduce the practical effect of the equipment. Utility Model Content
[0004] The purpose of the utility model is to provide an automatic air curtain type inflatable plate press to solve the problem that the positioning accuracy of the placement plate in the existing automatic air curtain type inflatable plate press depends on the driving motor. If the motor itself is not accurate enough or wears out due to long-term operation, it will directly lead to deviation in the rotation positioning of the placement plate.
[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0006] The utility model is an automatic air curtain type inflatable plate press, comprising a base, a cover plate installed on the upper surface of the base, a support frame installed at one end of the base, a hydraulic cylinder installed on the upper surface of the support frame, the output end of the hydraulic cylinder passes through the support frame and is installed with an inflatable plate, a placement plate is provided on the upper surface of the cover plate, a placement groove is provided on the upper surface of the base, a drive assembly is provided inside the placement groove, a limiting assembly is provided on the lower surface of the cover plate, the limiting assembly is located at the upper end of the drive assembly, the drive assembly comprises a rotating shaft, one end of the rotating shaft is rotatably connected to the inner bottom of the placement groove, the other end of the rotating shaft passes through the cover plate and is installed with the placement plate, one end of the base is hinged with a side plate, and the outer surface of the side plate is provided with a pull block.
[0007] Further, the limiting component includes a connecting disk, the connecting disk is installed on the outer surface of the rotating shaft, a limiting hole and an inclined sliding groove are formed on the upper surface of the connecting disk, and one end of the inclined sliding groove is communicated with the limiting hole.
[0008] Further, a housing is installed on the lower surface of the cover plate, a baffle is installed on the lower surface of the housing, a slider is slidably connected inside the housing, a limiting rod is installed on the lower surface of the slider, one end of the limiting rod penetrates through the baffle and extends downward, a spring is installed on the upper surface of the slider, and the other end of the spring is installed on the inner top of the housing.
[0009] Further, one end of the limiting rod moves along the axis direction of the inclined sliding groove, and the limiting rod is fitted and installed inside the limiting hole.
[0010] Further, an auxiliary groove is formed on the inner surface of the housing, an auxiliary block is arranged on the outer surface of the slider, and the auxiliary block is slidably connected inside the auxiliary groove.
[0011] Further, a toothed ring is installed on the outer surface of the connecting disk, a driving motor is installed inside the placement groove, a driving wheel is installed at the output end of the driving motor, and the driving wheel is meshed and connected with the toothed ring.
[0012] The utility model has the following beneficial effects:
[0013] (1) During the rotation and positioning of the placement plate of the utility model, the connecting disk rotates synchronously with the rotating shaft. At this time, the lower end of the limiting rod fixed under the cover plate is forced to slide along the inclined sliding groove on the upper surface of the connecting disk. The rising slope of the inclined sliding groove forces the limiting rod to move upward, thereby driving the slider to compress the spring inside the housing and store elastic potential energy. When the connecting disk rotates to a preset angle, the limiting rod just slides to the position above the limiting hole. At this time, the constraint of the inclined sliding groove on the limiting rod disappears, and the compressed spring restores its elasticity and releases the stored energy, pushing the slider and the limiting rod downward. Driven by the strong force of the spring, the limiting rod accurately inserts downward into the limiting hole in the vertical direction. When the limiting rod is completely inserted into the limiting hole, the circumferential rotation freedom of the connecting disk is rigidly restricted. Therefore, even if the driving motor itself has insufficient accuracy or the final stop position of driving the driving wheel and the toothed ring is deviated due to long-term operation and wear, the forced mechanical engagement between the limiting rod and the limiting hole can ensure that the connecting disk and the rotating shaft and the placement plate rigidly connected thereto are accurately locked at the preset target working position, eliminating the positioning deviation of the placement plate caused by motor error or wear, thereby ensuring the accuracy of the pressure application position of the subsequent inflatable plate on the paper and the consistency of the processing effect.
[0014] (2) In the present utility model, through the sliding connection between the auxiliary groove and the auxiliary block, this sliding fit forms a rigid guiding constraint, eliminating the possible radial offset or rotational tendency of the slider during movement. The movement trajectory of the slider is forced to be vertical, and the movement trajectory of the limiting rod rigidly connected thereto is also strictly restricted to be vertical. This enables the limiting rod to always accurately align with the lower limiting hole during the downward insertion process, avoiding poor insertion or angular deviation caused by lateral friction or jamming.
[0015] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1 - 4 As shown in the figure, the present utility model is an automatic air curtain type inflatable plate press, which includes a base 1. A cover plate 2 is installed on the upper surface of the base 1. One end of the base 1 is installed with a support frame 3. A hydraulic cylinder 4 is installed on the upper surface of the support frame 3. The output end of the hydraulic cylinder 4 penetrates through the support frame 3 and is installed with an inflatable plate 5. A placement plate 6 is arranged on the upper surface of the cover plate 2. A placement groove is opened on the upper surface of the base 1. A driving component is arranged inside the placement groove. A limiting component 8 is arranged on the lower surface of the cover plate 2. The limiting component 8 is located above the driving component. The driving component includes a rotating shaft 701. One end of the rotating shaft 701 is rotatably connected to the inner bottom of the placement groove. The other end of the rotating shaft 701 penetrates through the cover plate 2 and is installed with the placement plate 6. One end of the base 1 is hinged with a side plate 9. A pulling block 901 is arranged on the outer surface of the side plate 9;
[0025] By providing the limiting component 8, the circumferential rotational freedom of the placement plate 6 is rigidly restricted. Therefore, the positioning deviation of the placement plate 6 caused by motor error or wear is eliminated, thereby ensuring the accuracy of the pressure application position of the inflatable plate 5 on the paper during subsequent pressing and the consistency of the processing effect;
[0026] The limiting component 8 includes a connecting disc 801. The connecting disc 801 is installed on the outer surface of the rotating shaft 701. A limiting hole 802 and an inclined sliding groove 803 are opened on the upper surface of the connecting disc 801. One end of the inclined sliding groove 803 is communicated with the limiting hole 802;
[0027] A housing 804 is installed on the lower surface of the cover plate 2. A baffle 805 is installed on the lower surface of the housing 804. A slider 806 is slidably connected inside the housing 804. A limiting rod 807 is installed on the lower surface of the slider 806. One end of the limiting rod 807 penetrates through the baffle 805 and extends downward. A spring 808 is installed on the upper surface of the slider 806. The other end of the spring 808 is installed on the inner top of the housing 804;
[0028] One end of the limiting rod 807 moves along the axial direction of the inclined sliding groove 803. The limiting rod 807 is fitted and installed inside the limiting hole 802;
[0029] An auxiliary groove 809 is opened on the inner surface of the housing 804. An auxiliary block 8010 is arranged on the outer surface of the slider 806. The auxiliary block 8010 is slidably connected inside the auxiliary groove 809;
[0030] Through the sliding connection between the auxiliary groove 809 and the auxiliary block 8010, this sliding fit forms a rigid guiding constraint, eliminating the possible radial offset or rotational tendency of the slider 806 during movement. The movement trajectory of the slider 806 is forced to be vertical, and the movement trajectory of the limiting rod 807 rigidly connected to it is also strictly restricted to be vertical. This enables the limiting rod 807 to always accurately align with the lower limiting hole 802 during the downward insertion process, avoiding unsmooth insertion or angular deviation caused by lateral friction or jamming.
[0031] A toothed ring 702 is installed on the outer surface of the connecting disk 801, a driving motor 703 is installed inside the placement groove, and a driving wheel 704 is installed at the output end of the driving motor 703. The driving wheel 704 is meshed and connected with the toothed ring 702.
[0032] During use, first, two pieces of paper are accurately placed on the placement plate 6. Subsequently, the driving motor 703 is started, and its output shaft directly drives the driving wheel 704 rigidly connected to it to rotate. The rotation of the driving wheel 704 drives the meshing toothed ring 702 to rotate synchronously through the meshing action. Since the toothed ring 702 is coaxially fixed with the connecting disk 801, and the connecting disk 801 is fixedly connected to the rotating shaft 701, the rotational movement of the toothed ring 702 is transmitted to the rotating shaft 701, driving the rotating shaft 701 to rotate around its axis. Finally, the rotational movement of the rotating shaft 701 directly drives the placement plate 6 fixed at its upper end to rotate, sending the carried paper directly below the inflatable plate 5. The driving motor 703 is temporarily turned off. Then, the hydraulic cylinder 4 drives the inflatable plate 5 to press down, evenly pressing the paper with its flexible surface to perform pressing processing on the paper. After the paper is processed, the output end of the hydraulic cylinder 4 is operated to reset, so that the inflatable plate 5 cancels the acting force on the paper. Then, the driving motor 703 is operated to make the placement plate 6 rotate, so that the processed paper is separated from directly below the inflatable plate 5. After that, the paper can be removed from the placement plate 6 to complete the processing operation.
[0033] During the rotational positioning of the placement plate 6, the connecting plate 801 rotates synchronously with the rotating shaft 701. At this time, the lower end of the limiting rod 807 fixed under the cover plate 2 is forced to slide along the inclined chute 803 on the upper surface of the connecting plate 801. The upward slope of the inclined chute 803 forces the limiting rod 807 to move upward, thereby driving the slider 806 to compress the spring 808 in the outer shell 804 and store elastic potential energy. When the connecting plate 801 rotates to a preset angle, the limiting rod 807 just slides to a position above the limiting hole 802. At this time, the constraint of the inclined chute 803 on the limiting rod 807 disappears, and the compressed spring 808 restores its elasticity and releases the stored energy, pushing the slider 806 and the limiting rod 807 downward. Driven strongly by the spring 808, the limiting rod 807 accurately inserts vertically downward into the limiting hole 802. When the limiting rod 807 is completely inserted into the limiting hole 802, the circumferential rotational freedom of the connecting plate 801 is rigidly restricted. Therefore, even if the driving motor 703 has insufficient accuracy itself or there is a deviation in the final stop position of its driving the driving gear 704 and the gear ring 702 due to long-term operation wear, the forced mechanical engagement between the limiting rod 807 and the limiting hole 802 can ensure that the connecting plate 801, as well as the rotating shaft 701 and the placement plate 6 rigidly connected thereto, are accurately locked at the preset target working position, eliminating the positioning deviation of the placement plate 6 caused by motor error or wear, thereby ensuring the accuracy of the pressure application position of the subsequent inflatable plate 5 on the paper and the consistency of the processing effect.
