Description

Technical Field

[0001] The utility model relates to the technical field of tableware processing, and specifically relates to a forming device for tableware production. Background Technique

[0002] Melamine is a thermosetting plastic with a highly cross-linked molecular structure that forms a three-dimensional network structure. This dense structure endows melamine with excellent hardness, heat resistance, and chemical corrosion resistance, making it widely used in the fields of tableware, dinner plates, etc. However, the molecular chains in melamine are tightly bonded and lack flexibility, resulting in poor toughness and easy brittle fracture. Especially during mechanical processing such as grinding, the melamine material is extremely prone to stress concentration, thus causing defects such as chipping and cracking, seriously affecting the product yield.

[0003] To solve the brittleness problem of melamine materials during processing, the traditional process usually adopts the method of preheating and edging. By preheating, the glass transition temperature of the melamine material can be temporarily reduced, and the activity of its molecular chains can be increased, thereby slowing down stress concentration and reducing the risk of brittle fracture. However, the preheating process requires additional heating equipment and energy consumption, increasing production costs, and the control of the preheating temperature is also relatively complex. Therefore, it is of great practical significance to design a forming device for tableware production that saves preheating energy consumption. Content of the Utility Model

[0032] As shown in the attached Figure 1-7 A molding device for tableware production shown in the figure includes a conveyor belt 1; a molding mechanism is arranged at one end of the conveyor belt 1, and the materials processed by the molding mechanism are automatically conveyed to the next processing step through the conveyor belt 1, improving production efficiency. The molding mechanism includes a frame 21, a hydraulic column 22, an upper mold 221 and a demolding assembly 23. The hydraulic column 22 is fixedly installed on the frame 21, and the movable end of the hydraulic column 22 is fixedly connected to the upper mold 221. The molding mechanism realizes the precise molding of materials through the cooperation of the hydraulic column 22 and the upper mold 221.

[0033] The demolding assembly 23 is arranged on the lower mold 231; a cavity 2311 is formed on the surface of the lower mold 231, and a plurality of chutes 2312 are arranged around the cavity 2311 of the lower mold 231, and through holes 2313 are formed in the bottom surface of the chutes 2312. The demolding assembly 23 includes a telescopic rod 25 and a demolding seat 232, and the movable end of the telescopic rod 25 passes through the through hole 2313 and is fixedly connected to the demolding seat 232.

[0034] In this embodiment, the telescopic rod 25 can be a mechanical push rod, an electric push rod or a hydraulic rod, etc. Since its structure is well known to those skilled in the art, it will not be described in detail in this specification.

[0035] A grinding assembly and a dust suction assembly are further arranged on the conveyor belt 1. The grinding assembly grinds the formed product to improve the surface quality of the product, while the dust suction assembly effectively collects the dust generated during the grinding process to keep the production environment clean.

[0036] In some embodiments, the grinding assembly includes a first vertical hydraulic column 31, a second vertical hydraulic column 32 and a suction cup 33. The movable end of the first vertical hydraulic column 31 is connected to a moving plate 34, and a grinding machine is fixedly connected to the moving plate 34. The moving plate 34 connected to the movable end of the first vertical hydraulic column 31 drives the grinding machine to move up and down. The suction cup 33 is coaxially arranged below the grinding machine, and the suction cup 33 is fixedly connected to the movable end of the second vertical hydraulic column 32. The second vertical hydraulic column 32 can move the suction cup 33 in a direction close to or away from the grinding machine. The design of the suction cup 33 ensures that the product can be stably fixed below the grinding machine during the grinding process, avoiding the movement or deviation of the product during the grinding process.

[0037] In some embodiments, the grinding assembly further includes a horizontal push rod 36. The horizontal push rod 36 is arranged on the left and right sides of the grinding machine, and the movable end of the horizontal push rod 36 is fixedly connected with a centering jaw 361. The horizontal push rod 36 can move in a direction close to or away from each other at the same time. By setting the centering jaw 361, not only can the tableware be firmly clamped during the grinding process to avoid movement or deviation and improve the grinding accuracy, but also the center of the tableware can be adjusted during the clamping process of the tableware, so that the tableware is in a position coaxial with the grinding machine, thereby improving the grinding effect on the tableware.

[0038] When the formed tableware is conveyed to the grinding assembly by the conveyor belt 1, at this time, the horizontal push rod 36 moves in the direction of approaching each other to grip the tableware, and under the action of the centering jaw 361, the position of the tableware is adjusted so that the tableware is in a position coaxial with the grinding machine. Subsequently, the first vertical hydraulic cylinder 31 drives the moving plate 34 and the grinding machine to move downward, so that the grinding machine abuts against the upper end surface of the tableware. The second hydraulic cylinder 32 drives the suction cup 33 to move upward, so that the suction cup 33 abuts against the lower end surface of the tableware and evacuates the air between the lower end of the dinner plate and the suction cup 33, so that the tableware is fixed on the suction cup 33. Cooperating with the grinding machine to apply a certain pressure to the tableware at the upper and lower ends of the tableware, bringing a better fixing effect on the tableware. Finally, the grinding machine grinds the tableware.

[0039] In some embodiments, the grinding machine includes a grinding frame 352 and a grinding motor 351 drivingly connected to the grinding frame 352. Grinding sheets are provided on both the inner side wall and the inner top wall of the grinding frame 352. Thus, the tableware can be comprehensively ground during the grinding process, improving the surface quality of the product. At the same time, the grinding frame 352 also plays a certain fixing role, further preventing the tableware from shaking during the grinding process.

[0040] In some embodiments, the dust collection assembly includes a collection chamber 41. A negative pressure fan 42 is provided in the collection chamber 41. A slant guide plate 43 is fixed above the negative pressure fan 42. An openable cavity 44 is provided at the bottom of the collection chamber 41. A folded channel is provided between the cavity 44 and the negative pressure fan 42. The guide plate 43 is used to direct impurities to the side away from the negative pressure fan 42 to prevent impurities from directly falling into the negative pressure fan 42. The folded channel is used to prevent larger particulate impurities from entering, so as to achieve the separation of dust and larger particulate matter and avoid damage to the negative pressure fan 42 caused by larger particulate matter. The impurities in the collection chamber 41 can be quickly cleaned through the openable cavity 44.

[0041] In some embodiments, the folded channel includes a first baffle 451 fixed to the lower part of the end of the guide plate 43 away from the negative pressure fan 42. A second baffle 452 is fixed on the inner wall of the collection chamber 41 between the first baffle 451 and the negative pressure fan 42. The first baffle 451 and the second baffle 452 form a folded channel, which does not affect the air flow effect of the negative pressure fan 42, and can prevent larger particulate matter from entering the negative pressure fan 42 through the second baffle 452, realizing the separation of dust and larger impurities and protecting the negative pressure fan 42.

[0042] In some embodiments, the demolding seat 232 includes a seat body 2321 and a movable rod 2322 hinged to the seat body 2321, one end of the movable rod 2322 hinged to the seat body 2321 is connected to a fan tooth 23221, a motor 2323 is fixedly arranged on the seat body 2321, and a worm 23231 is provided at the output end of the motor 2323, which is transmission-connected to the fan tooth 23221, and the movable rod 2322 is rotated in a clockwise or counterclockwise direction by the motor 2323.

[0043] In some embodiments, a plurality of jet holes 23211 are formed at the top of the seat body 2321 . The jet holes 23211 are connected to an air pump, and the air pump sprays gas out of the jet holes 23211 .

[0044] In some embodiments, the molding mechanism further includes a hydraulic pushing column 24, which is fixedly mounted on the frame 21, and a push plate 241 is connected to the movable end of the hydraulic pushing column 24. The hydraulic pushing column 24 can move toward or away from the conveyor belt 1.

[0045] The working principle of the utility model is as follows:

[0046] During processing, the melamine block is placed on the vertical center axis of the cavity 2311. After the upper mold 221 and the lower mold 231 on the molding mechanism are pressed together, most of the melamine block is pressed and covers the cavity 2311 to form a disc shape, while a small part of the excess melamine block is pushed and overflows on the upper end surface of the seat 2321 and the movable rod 2322, thereby forming uneven scraps at the edge of the disc-shaped tableware. Subsequently, the telescopic rod 25 drives the seat 2321 to move upward in the slide groove 2312, thereby driving the entire demoulding seat 232 to move upward, thereby evenly loosening the entire disc-shaped tableware and the cavity 2311. At the same time, the air pump sprays gas from the top of the seat 2321 to the surrounding area through the jet hole 23211, so that the gas flows into the space between the disc-shaped tableware and the seat 2321, which is conducive to the separation of the disc-shaped tableware from the seat 2321. At the same time, the motor 2323 is started, driving the movable rods 2322 to rotate in a direction away from each other, thereby opening a gap so that the tableware can be pushed out smoothly.

[0047] Subsequently, the hydraulic pushing column 24 is started, driving the pushing plate 241 to move toward the conveyor belt 1, thereby pushing the formed tableware onto the conveyor belt 1. Under the action of the conveyor belt 1, the tableware is conveyed to the polishing assembly for polishing. Finally, the conveyor belt 1 conveys the polished tableware to the next step.

[0048] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
