Description

Technical Field

[0001] This utility model relates to the technical field of tablet press auxiliary devices, specifically an anti-pinch device for a powder coating tablet press. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. Unlike ordinary solvent-based and water-based coatings, their dispersion medium is air, not solvent or water. A tablet press is a device that applies pressure to powder coatings.

[0003] However, in the tablet extruder, the molten material at the die head drips onto the rotating pressure rollers via free fluid movement, where it is cooled and extruded to form uniform thin sheets. A drawback of the original device is that the protective cover opening is too large, making it easy to reach in and cause injury in case of malfunction. Other issues include damage to the pressure rollers caused by foreign objects falling in. Utility Model Content

[0004] The purpose of this invention is to provide an anti-pinch device for a powder coating tablet press, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-pinch device for a powder coating tablet press, comprising a protective cover, wherein the protective cover includes a cover body and a cover plate disposed on the top of the cover body.

[0006] A hinge connects the cover body and the cover plate. A locking block is fixed to the side of the cover body, and the locking block has a slot with a locking screw hole. By connecting the cover plate and the cover body with the hinge, the cover plate can be opened. The locking block locks the cover plate in place.

[0007] A locking plate is fixed to the side of the cover plate, and the locking plate is engaged in a slot. The locking plate has a positioning groove, which is aligned with the locking screw hole and connected to a locking pin. The cover plate is fixed by the locking pin to prevent it from being opened.

[0008] As a preferred embodiment of this utility model, the cover plate is provided with a feeding gap on the side away from the hinge. After a protective cover is installed above the feeding port of the powder coating tablet press, the feeding gap is used for feeding, and the feeding gap is 10mm.

[0009] As a preferred embodiment of this utility model, the cover is U-shaped, with one end of its opening facing the powder coating tablet press, and the feeding gap is also located at one end of the U-shaped opening.

[0010] As a preferred embodiment of this utility model, a mounting plate is provided below the cover, and mounting holes are provided on the mounting plate. The mounting plate is used to fix the cover, which is fixed by bolts through the mounting holes, or other methods can be used for fixing.

[0011] As a preferred embodiment of this invention, the locking plate is L-shaped to facilitate inserting one side of the locking plate into the slot.

[0012] As a preferred embodiment of this utility model, an auxiliary handle is fixed above the cover plate, which is mainly for the convenience of opening the cover plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention improves operational safety and reliability by installing a protective cover above the original material discharge port, leaving only a single discharge gap. The cover is hinged for easy opening during machine shutdown. It also prevents personal injury from improper operation and damage to the pressure rollers from falling foreign objects.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an anti-pinch device for a powder coating tablet press, including a protective cover, the protective cover including a cover body 1 and a cover plate 2 disposed on the top of the cover body 1.

[0024] Furthermore, a hinge 3 connects the cover 1 and the cover plate 2. A locking block 101 is fixed to the side of the cover 1. The locking block 101 has a slot 1011 and a locking screw hole 1012. By connecting the cover plate 2 and the cover 1 with the hinge 3, the cover plate 2 can be opened. The locking block 101 locks the cover plate 2 in place.

[0025] Furthermore, a locking plate 201 is fixed to the side of the cover plate 2. The locking plate 201 is engaged in the slot 1011. The locking plate 201 has a positioning groove 2011, which is aligned with the locking screw hole 1012 and connected to a locking screw 4. The cover plate 2 is fixed by the locking screw 4 to prevent it from being opened.

[0026] Furthermore, a material feeding gap is provided on the side of the cover plate 2 away from the hinge 3. After a protective cover is installed above the material discharge port of the powder coating tablet press, the material feeding gap is used for material feeding, and the material feeding gap is 10mm.

[0027] Furthermore, the cover 1 is U-shaped, with one end of its opening facing the powder coating tablet press, and the material feeding gap is also located at one end of the U-shaped opening.

[0028] Furthermore, a mounting plate 102 is provided below the cover 1. The mounting plate 102 has mounting holes and is used to fix the cover 1. It is fixed by bolts through the mounting holes, or other methods can be used for fixing.

[0029] Furthermore, the locking plate 201 is L-shaped to facilitate inserting one side of the locking plate 201 into the slot 1011.

[0030] Furthermore, an auxiliary handle 202 is fixed above the cover plate 2. The auxiliary handle 202 is mainly designed to facilitate opening the cover plate 2.

[0031] In summary, when using this device, simply install the protective cover above the original material inlet. During the operation of the powder coating tablet press, the material feeding gap 203 on the protective cover is used for material feeding. During the process, the protective cover prevents injury from reaching in during malfunctions. It also prevents damage to the pressure rollers caused by foreign objects falling in. When it is necessary to open the cover plate 2 for operation, simply unscrew the locking pin 4 from the locking screw hole 1012. After unscrewing, the cover plate 2 can be opened, facilitating operation. To close the cover plate 2, reattach it to the cover body 1, insert the locking plate 201 into the slot 1011 on the locking block 101, and then insert the locking pin 4 from the positioning slot 2011 and screw it back into the locking screw hole 1012.

[0032] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
