Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of decoration diamond production, especially relates to a double-station diamond screening structure of a plastic suction machine, which can be used for a four-station plastic suction machine. BACKGROUND

[0002] In the process of painting or silver plating of decoration diamonds, the decoration diamonds need to be fixed on a plastic suction sheet with a specific side exposed. The prior art can fix the decoration diamonds on the plastic suction sheet through a plastic suction machine. In order to improve efficiency, there are two-station or four-station plastic suction machines in the prior art.

[0003] For example, patent No. CN202210025044.4 discloses a decoration diamond plastic suction integrated device, which includes a first diamond screening station for screening decoration diamonds placed in the first diamond screening station, a second diamond screening station for screening decoration diamonds placed in the second diamond screening station, a plate combining station for combining the screening plate and the suction plate, a lower mechanical arm assembly for sending the screening plate to the plate combining station, a plate separating station for separating the suction plate from the screening plate and transferring the decoration diamonds to the suction plate, an upper mechanical arm assembly for transporting the combined suction plate and screening plate to the plate separating station and sending the separated screening plate to the first diamond screening station or the second diamond screening station, a plastic suction station for plastic suction treatment of the film and the decoration diamonds on the suction plate, and a rotating mechanical arm assembly for transferring the suction plate to the plastic suction station.

[0004] The existing double-station diamond screening structure includes two diamond screening stations arranged side by side, powder scattering mechanisms beside the diamond screening stations, mechanical arm assemblies above the diamond screening stations, and storage mechanisms below the diamond screening stations. Each diamond screening station is provided with one powder scattering mechanism and one storage mechanism, and the number of powder scattering mechanisms and storage mechanisms is two (the number of discharge mechanical arms is also two). The mechanical arm assemblies can move forward and backward and vertically, the powder scattering mechanisms can move forward and backward and vertically, and the diamond screening stations can be flipped to pour the decoration diamonds (flowing out of the discharge port) into the corresponding storage mechanisms.

[0005] In the prior art, the number of powder scattering mechanisms and storage mechanisms is two. The powder scattering mechanism (as shown in the prior art) needs to move vertically and forward and backward and needs to control the discharge, which results in a complex structure of the powder scattering mechanism. The bottom of the storage mechanism needs to be provided with a linear feeder, which is also relatively complex. This results in a complex overall structure of the diamond screening structure.

[0024] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in further detail below in conjunction with the drawings.

[0025] Embodiment 1

[0026] Referring to Figure 1-5 Embodiment 1 provides a double position sieve drilling structure of blister machine, which comprises a lifting mechanism 5, a powder scattering mechanism 2, a storage mechanism 4, a storage mechanism 4, a mechanical arm assembly and two sieve drilling positions 1.

[0027] The two sieve-drilling stations 1 are arranged side by side with a spacing therebetween. The jointing station is arranged in front of or behind the two sieve-drilling stations 1. The two sieve-drilling stations 1 share a storage mechanism 4, a powder scattering mechanism 2 and a mechanical arm assembly. The sieve-drilling stations 1 can be flipped to dump the decorative drills to the powder scattering mechanism 2. The sieve-drilling station 1 in front can be flipped backward and its discharge port (arranged in the left-right direction and provided with an openable valve) is located at the rear end. The sieve-drilling station 1 in the rear can be flipped forward and its discharge port is located at the front end. The sieve-drilling stations 1 can vibrate in the front-rear direction.

[0028] The mechanical arm assembly is arranged above the sieve-drilling stations 1 and can move in the front-rear direction and the vertical direction. It is used to transfer the sieve plate between the sieve-drilling station 1 (two) and the jointing station. The powder scattering mechanism 2 can move to below the discharge ports of the two sieve-drilling stations 1, directly above the two sieve-drilling stations 1 and directly below the high-position lifting mechanism 5. The discharge of the sieve-drilling stations 1 is poured into the powder scattering mechanism 2 (usually not output to the storage mechanism 4). That is, the powder scattering mechanism 2 has two inputs: one is the output of the sieve-drilling station 1 (to realize the recycling of excess decorative drills), and the other is the output of the lifting mechanism 5.

[0029] The powder scattering mechanism 2 can move in the front-rear direction and the vertical direction and is arranged between the two sieve-drilling stations 1 and on the left side of the sieve-drilling stations 1. Specifically, the powder scattering mechanism 2 includes a front-rear sliding structure (specifically a sliding seat) that can move in the front-rear direction on a lower sliding rail 6 (driven by a synchronous belt driving structure, a lead screw driving structure or a rack driving structure, etc.), a left vertical sliding rail arranged on the upper side of the front-rear sliding structure and in the vertical direction, a lifting sliding structure (specifically a sliding block) arranged on the left vertical sliding rail and sliding in the vertical direction (driven by a synchronous belt driving structure, a lead screw driving structure or a rack driving structure, etc.), a fixed arm arranged on the right side of the lifting sliding structure and in the left-right direction, and a feeding hopper (arranged in the left-right direction and tapered at the bottom) at the right end of the fixed arm.

The decorative drills in the storage mechanism 4 can be output to the lifting mechanism 5. When the lifting mechanism 5 is in the high position, it is directly above the powder scattering mechanism 2. The decorative drills in the lifting mechanism 5 can be output to the powder scattering mechanism 2.

[0031] Specifically, the lifting mechanism 5 includes a sliding block 51 slidingly arranged on the right vertical sliding rail 3, a driving assembly (a synchronous belt driving structure, a screw driving structure, or a rack driving structure, etc.) between the sliding block 51 and the right vertical sliding rail 3 and used for driving the vertical movement of the sliding block 51, a fixed plate 52 on the top left side of the sliding block 51, a skip 53 hingedly arranged on the lower side of the fixed plate 52, a turnover cylinder 54 used for driving the turnover of the skip 53, etc. The fixed plate 52 is specifically a rectangular plate arranged along the left-right direction.

When the skip 53 is located at the low position, it is located directly below the discharge port of the storage mechanism 4. When the skip 53 is located at the high position, the feeding hopper can move to be directly below the skip 53. When the turnover cylinder 54 is extended, the skip 53 is turned downward to pour the decorative diamonds into the feeding hopper.

Specifically, the recovery groove 42 of the front diamond screening station 1 is located below and behind the corresponding diamond screening station 1, and the recovery groove 42 of the rear diamond screening station 1 is located below and in front of the corresponding diamond screening station 1.

The discharge groove can be specifically a linear feeder (arranged along the left-right direction) as shown in CN202210025044.4. When the lifting mechanism 5 is located at the low position, the skip 53 is located below and right of the discharge groove. When the lifting mechanism 5 moves vertically, it can pass over the discharge groove. When the discharge groove is extended, the right end of the discharge groove is located directly above the skip 53 at the low position.
