Description

Technical Field

[0001] The utility model relates to the technical field of hot presses, in particular to a bottom-mounted fully automatic multi-layer hot press. Background Art

[0002] When the hot pressing process is carried out after the slab is glued, assembled and pre-pressed, the hot pressing plate is required to be able to close and pressurize quickly, thereby completing the working process of the hot pressing machine, so that the slab can be hot pressed between multiple layers of hot pressing plates.

[0003] In the prior art, the Chinese patent with the authorization announcement number CN115122697A discloses a multi-layer hot press, including a hot press drive mechanism, a base, a movable plate, a fixed seat, multiple pressing plates, multiple guide pillars, multiple heating plates and multiple gravity compensation mechanisms, multiple guide pillars are connected between the base and the fixed seat, the movable plate is located on one side of the base, multiple pressing plates are located between the movable plate and the fixed seat, the hot press end of the hot press drive mechanism is used to apply hot pressure to the movable plate, the pressing plate located on one side of the fixed seat and the fixed seat, between two adjacent pressing plates, and between the pressing plate located on one side of the movable plate and the movable plate are respectively connected via a gravity compensation mechanism, and the side of the movable plate close to the pressing plate, the two sides of the pressing plate, and the side of the fixed seat close to the pressing plate are equipped with heating plates. It realizes the hot pressing treatment of multiple materials at one time, improves the hot pressing efficiency, eliminates the influence of gravity, makes the hot pressure of each material equal, and improves the effect and quality of hot pressing treatment.

[0004] The above mechanism eliminates the influence of gravity to make the thermal pressure on the material equal. However, in actual use, the heating plates are connected by guide pillars, which causes the distance between multiple heating plates to be controlled separately. At the same time, the traditional hot plate mold closing process from bottom to top needs to overcome the self-weight lifting of all hot pressing plates. According to the law of conservation of energy, increasing the speed will inevitably increase the power source. Excessive power source will increase the equipment cost and the corresponding power supply power on site. Utility Model Content

[0005] The purpose of the utility model is to provide a bottom-mounted fully automatic multi-layer hot press to solve the problem that the traditional hot platen needs to overcome the self-weight lifting of all hot press plates in the process of closing the mold from bottom to top as proposed in the above background technology. According to the law of conservation of energy, increasing the speed will inevitably increase the power source. An excessively large power source will increase the equipment cost and the corresponding power supply power on site.

[0006] To achieve the above object, the utility model provides the following technical solution: a bottom-mounted fully automatic multi-layer hot press, comprising a support leg, a mounting frame is installed on the top of the support leg, and a pneumatic telescopic rod is fixedly connected to one side of the mounting frame, and a hot pressing plate is arranged at one end between the mounting frames;

[0007] Both ends of one side of the hot pressing plate are rotatably connected with a first limit block, and both ends of the first limit block are provided with a distance control mechanism for controlling the distance between the hot pressing plates, the distance control mechanism includes a limit groove, and the limit groove is opened at both ends of the other end of the hot pressing plate, the interior of the limit groove is slidably connected with a sliding block, and one end of the sliding block is rotatably connected with a second limit block, and one end of the first limit block and the second limit block are fixedly connected with a hinge rod;

[0008] A mounting plate is fixedly connected to one side of the mounting frame, and a feeding mechanism for auxiliary feeding is snap-fitted and connected between the mounting plates.

[0009] Furthermore, a limiting mechanism for controlling the hinged rod is provided on one side inside the limiting groove, and the limiting mechanism includes a movable plate, and the movable plate is slidably connected to the inside of the limiting groove, one side of the movable plate and one side inside the limiting groove are both fixedly connected with conductive sheets, and the positions of the conductive sheets correspond to each other, and one side of the sliding block is fixedly connected with a connecting rod.

[0010] Furthermore, a limiting mechanism for controlling the hinged rod is provided on one side inside the limiting groove, and the limiting mechanism includes a movable plate, and the movable plate is slidably connected to the inside of the limiting groove, one side of the movable plate and one side inside the limiting groove are both fixedly connected with conductive sheets, and the positions of the conductive sheets correspond to each other, and one side of the sliding block is fixedly connected with a connecting rod.

[0011] Furthermore, the feeding mechanism includes a feeding roller, and the feeding roller is arranged on one side between the mounting plates, connecting plates are arranged at both ends of the feeding roller, and the connecting plates and the feeding roller are rotatably connected, the four corners on one side of the connecting plate are fixedly connected with fixing blocks, and the four corners on one side of the mounting plate are provided with fixing grooves matching the fixing blocks.

[0012] Furthermore, both ends of the mounting frame are fixedly connected with mounting boxes, and one side inside the mounting box is slidably connected with a limiting rod, and one side of the limiting rod passes through and extends to the outside of the mounting plate.

[0013] Furthermore, a slot is provided on one side of the mounting plate, and a block matching the slot is fixedly connected to the outer side of the limiting rod.

[0014] Furthermore, a return spring is fixedly connected to one side of the limit rod, and one side of the return spring is connected to one side inside the installation box to form an elastic structure:

[0015] 1. According to the hot pressing process, the slab needs to be closed quickly before hot pressing, and the mold needs to be opened slowly after hot pressing. The hot pressing plate itself has a certain weight. Using this, the mold is closed by descending by its own weight. This function only needs to increase the descending control valve. The mold opening process relies on lifting the pneumatic telescopic rod to open the mold slowly, which meets the overall hot pressing process requirements. The output end of the pneumatic telescopic rod can drive the upper frame and the hot pressing plate to move, so that the height of the hot pressing plate is increased. The hot pressing plates are hinged by hinged rods, so that the separable distance between the hot pressing plates is fixed, which is convenient for loading and processing the slabs between the hot pressing plates;

[0016] Furthermore, in the process of separating the hot pressing plates, the hinge rod can be used to limit the distance between the hot pressing plates. At the same time, through the rotation of the first limit block and the second limit block, the hinge rod can be rotated to different angles according to different needs to control the distance between the hot pressing plates. In the process of rotating the hinge rod, due to the change in the distance between the hot pressing plates, the sliding block slides inside the limit groove to adjust the distance between the second limit block and the first limit block, so that the rotation adjustment of the hinge rod can be smoother.

[0017] Furthermore, during the rotation adjustment process of the hinged rod, the connecting rod at one end of the hinged rod slides inside the limiting groove, so that one side of the connecting rod fits with the movable plate, and then the connecting rod pushes the movable plate inward, so that the conductive sheet on one side of the movable plate contacts and is energized with the conductive sheet inside the limiting groove, and the first limiting block and the second limiting block are controlled to stop rotating, and at the same time, the first limiting block and the second limiting block of the next layer are controlled to rotate, so as to control the hinged rod of the next layer to rotate and pull to adjust the spacing of the hot pressing plates;

[0018] 2. The feeding roller can be used to guide the slab during feeding. The rotation of the feeding roller also makes it easier to push the slab between the hot pressing plates, thereby reducing the time wasted during feeding. The clamping block is pulled outward by pulling the limit rod, and the limit rod pops out by the elastic force of the return spring. The clamping block passes through the clamping slots provided on the mounting plate and the connecting plate, and is engaged and limited with the lower end of the clamping slot. The fixing block is engaged with the fixing slot, so that the connecting plate is fixed to one side of the mounting plate, thereby realizing the basic fixation of the position of the feeding roller, thereby realizing the secondary limit of the position of the feeding roller, and avoiding the feeding roller from falling due to the repeated movement of the slab during the feeding process.

[0019] Furthermore, the elastic force of the return spring can assist the limit rod in resetting its position during disassembly, avoiding the need to repeatedly manually adjust the position of the limit rod. At the same time, when the limit rod and the slot are engaged, the elastic force of the limit rod can also pull the limit rod in the opposite direction, so that the limit rod and the slot can be engaged more tightly.

[0035] In this example, during the separation of the hot pressing plates 3, the hinged rod 8 can be used to limit the distance between the hot pressing plates 3. At the same time, through the rotation of the first limit block 5 and the second limit block 6, the hinged rod 8 can be rotated to different angles according to different needs to control the distance between the hot pressing plates 3.
