Description

Technical Field

[0001] This utility model relates to the field of flame-retardant plastic production technology, and in particular to a pressing device for flame-retardant plastic production. Background Technology

[0002] Flame retardant materials are a class of materials that can inhibit or delay combustion and are themselves not easily combustible. They are widely used in clothing, petroleum, chemical, metallurgy, shipbuilding, fire protection, national defense, and many other fields. These materials consist of a base material and a top material. The current production steps are as follows: First, the base material is placed on a workbench. Then, adhesive is manually applied to the surface of the base material. Next, the top material is manually placed on top of the base material, using the adhesive on the base material to bond the two materials together. Finally, a pressing device is manually operated to press the bonded base and top materials together.

[0003] In current flame-retardant plastic production pressing equipment, when spraying adhesive onto flame-retardant plastic substrates of different sizes, the adhesive sprayed within a fixed range often exceeds the edge of the substrate and is directly sprayed onto the workbench or equipment frame, resulting in ineffective waste. At the same time, when the adhesive between the upper and lower materials is compressed, the excess adhesive will be squeezed out along the edge of the substrate in large quantities. This overflowing adhesive cannot participate in effective bonding and will fall into the gaps between the equipment or the ground due to gravity, resulting in a significant waste of adhesive. Therefore, this application provides a flame-retardant plastic production pressing device to meet the needs. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide a pressing device for the production of flame-retardant plastics. This device addresses the issue that, when applying adhesive to flame-retardant plastic substrates of different sizes, the adhesive sprayed from a fixed area often exceeds the edge of the substrate and is directly sprayed onto the workbench or equipment frame, resulting in ineffective waste. Furthermore, when the adhesive between the upper and lower materials is pressed and squeezed, the excess adhesive is squeezed out along the edge of the substrate. This overflowing adhesive cannot participate in effective bonding and will fall into the gaps between equipment or onto the ground due to gravity, leading to significant waste of adhesive.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A pressing device for producing flame-retardant plastics includes a processing frame, a preset area on the top of the processing frame, a mounting frame fixed in the middle of the preset area, clamping mechanisms on both sides of the middle of the preset area, a spraying mechanism mounted on the upper and lower parts of the processing frame table, a hydraulic cylinder mounted on the top of the processing frame, and a pressing plate connected to the extended end of the hydraulic cylinder, the spraying mechanism including a displacement component mounted on the top of the processing frame table, the displacement component including a guide frame, and uniform spraying components arranged on the upper and lower parts of the guide frame, a receiving frame connected to the bottom of the processing frame, and a drain port connected to one end of the receiving frame.

[0007] Optionally, the displacement component includes a preset groove, which is located on one side above the processing table surface. A transmission screw is installed in the middle of the preset groove, and a second motor is installed at one end of the transmission screw. A second screw sleeve is screwed around one side of the transmission screw, and a guide frame is fixed above the second screw sleeve. A guide groove is provided on the other side above the processing table surface.

[0008] Optionally, the guide frame and its guide groove are connected by a movable guide connection.

[0009] Optionally, the uniform spraying assembly includes a plunger pump, which is mounted above the guide frame. The two ends of the plunger pump are connected to connecting pipes, and one end of the connecting pipe is connected to an adhesive tank. A mounting block is fixed on one side of the guide frame, and a spraying frame is installed in the lower middle part of the guide frame. Spraying heads are provided at the bottom of the spraying frame, and external threads are provided around the bottom of the spraying heads. Thread plugs are screwed around the external threads.

[0010] Optionally, an adhesive tank is mounted on top of the mounting block.

[0011] Optionally, the threaded plug utilizes a threaded assembly connection formed between the external thread and the spray head.

[0012] Optionally, the receiving rack has an inclined interior design and is fixedly connected to the bottom of its processing rack.

[0013] Optionally, the clamping mechanism includes a sliding groove, which is disposed on both sides of the center of the preset area. A positive and negative lead screw is installed in the center of one of the sliding grooves, and a first motor is installed at one end of the positive and negative lead screw. First lead screw sleeves are screwed on both sides of the center of the positive and negative lead screws, and clamping plates are fixed on the inner sides of the two first lead screw sleeves. A blocking plate is fixed on the upper part of the two sliding grooves.

[0014] Optionally, the sliding groove is horizontally guided to its two clamping plates.

[0015] Optionally, the shielding plate is inclined and fixed to the upper inner side of the two sliding grooves.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting up a spraying mechanism, the operator can start a plunger pump, which, guided by connecting pipes at both ends, transports the adhesive from the adhesive tank to the spraying frame in the middle of the guide frame. The adhesive is then sprayed out through the spraying heads at the bottom of the spraying frame, thus achieving adhesive spraying on the surface of the flame-retardant substrate. During this process, the second motor is started simultaneously to rotate the transmission screw. At this time, the second screw sleeve, which interacts with the screw, will carry the above-mentioned spraying components to move horizontally under the guidance of the guide groove, thereby ensuring uniform spraying on the surface of the flame-retardant plastic substrate. After the spraying is completed, the operator can cover the adhesive on the surface of the substrate with the top layer material, and then use a hydraulic cylinder to drive the pressing plate to press the material together. When different sized substrates are involved, the operator can install threaded plugs under the corresponding spraying heads through external threads according to the actual situation, thereby reducing the adhesive spraying range and reducing waste. Excess adhesive overflowing from the edges during the pressing process will fall into the receiving rack and be discharged from the drain port through the inclined structure of the receiving rack. The operator only needs to use a collection box to receive the adhesive to complete the adhesive recycling.

[0018] By setting up a clamping mechanism, the operator can pre-place the flame-retardant plastic substrate in the upper central area of ​​the mounting frame, and then start the first motor to rotate the positive and negative lead screws. At this time, the two first lead screw sleeves that interact with the lead screws will carry their respective fixed clamping plates and move in opposite directions under the guidance of the sliding groove until they are stably clamped on both sides of the substrate. This structure is suitable for clamping and fixing substrates of different sizes. Attached Figure Description
