DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The embodiment of the present application provides a plastic press to solve the problem that the spiral extrusion equipment of many current plastic presses usually has no protection, has a high surface temperature, and poses a risk of scalding to personnel. The traditional method of installing a protective cover is fixed with multiple screws, which is inconvenient to disassemble and assemble, and it is not convenient to regularly inspect and maintain the spiral extrusion equipment.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] The utility model embodiment discloses a plastic press, according to the attached Figure 1-6 As shown, it includes a press support platform 1, a screw extruder 2 is fixedly connected to the press support platform 1, a feed hopper 3 is fixedly connected to the screw extruder 2, a protective mechanism is provided on the press support platform 1, and the protective mechanism includes a protective cover 4 slidably connected to the press support platform 1, guide rails 101 are provided on both sides of the press support platform 1, a socket seat 402 is fixedly connected to the protective cover 4, the socket seat 402 is socketed on the guide rail 101, and a card slot 401 corresponding to the position of the feed hopper 3 is opened on the protective cover 4;

[0028] A supporting and fixing plate 6 is fixedly connected to the protective cover 4, and a locking assembly is provided on the supporting and fixing plate 6. The locking assembly includes a locking sleeve 7 arranged on the supporting and fixing plate 6 and a locking pin 701 movably clamped on the locking sleeve 7. A sliding column 702 is slidably connected inside the locking sleeve 7. The sliding column 702 is used to support and limit the locking pin 701. A spring 703 is fixedly connected between the sliding column 702 and the locking sleeve 7. A pull rod 704 is fixedly connected to the sliding column 702. The pull rod 704 passes through the locking sleeve 7 and extends downward.

[0029] The locking component of the device is simply designed. Through the locking component design, the position of the protective cover 4 can be easily positioned and locked. The protective cover 4 can provide protection for the screw extruder 2 and its ancillary equipment. At the same time, it is also easy to quickly disassemble the protective cover 4, so that the screw extruder 2 and its ancillary equipment can be easily inspected and maintained.

[0030] A positioning plate 5 is provided at the bottom of the press support platform 1, and a first positioning hole 501 and a second positioning hole 502 are provided on the positioning plate 5. The lateral positions of the locking pin 701 are aligned with the first positioning hole 501 and the second positioning hole 502 respectively, and the locking pin 701 is movably connected to the inside of the positioning plate 5. When the locking pin 701 is inserted into the inside of the first positioning hole 501, the protective cover 4 provides protection for the top of the press support platform 1, protects the screw extruder 2 and its ancillary equipment, and prevents people from accidentally touching the screw extruder 2, thereby ensuring the safety of the people. When the locking pin 701 is inserted into the inside of the second positioning hole 502, the protective cover 4 is opened, which is convenient for people to inspect and maintain the screw extruder 2 and its ancillary equipment.

[0031] The bottom of the press support platform 1 is fixedly connected to a limit baffle 102. The design of the limit baffle 102 allows the protective cover 4 to be easily positioned during installation. When the protective cover 4 is in contact with the limit baffle 102, the locking pin 701 is aligned with the first positioning hole 501, making the installation of the protective cover 4 easy and easy to protect the device.

[0032] When installing the protective cover 4 of the plastic press, first pull the pull rod 704 downward, so that the pull rod 704 drives the sliding column 702 and the locking pin 701 to move as a whole and squeeze the spring 703. At this time, align the socket 402 and the guide bar 101, and then push the protective cover 4 horizontally, and use the protective cover 4 to provide protection for the upper part of the press support platform 1. When the protective cover 4 is in contact with the limit baffle 102, release the pull rod 704, and the spring 703 pulls and pushes the sliding column 702 and the locking pin 701 to move, so that the locking pin 701 is inserted into the first positioning hole 501, thereby realizing the loading positioning of the protective cover 4. When disassembling the protective cover 4, the above-mentioned installation process can be reversed.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
