Description

Technical Field

[0001] This utility model relates to the field of tray-feeding machine technology, and in particular to a tray-feeding device for tray-feeding machines. Background Technology

[0002] In the packaging industry, plastic trays are platforms that hold products, such as food trays and pharmaceutical trays. Pharmaceutical trays include trays for injections, oral liquids, or penicillin. Injection bottles, oral liquids, or penicillin vials are placed in the grooves of the plastic tray before being placed into the medicine box, ensuring stability within the box and preventing adjacent trays from colliding and breaking. A tray separating machine is specifically designed to automatically separate stacked plastic trays one by one using a suction head that generates negative pressure, allowing the trays to be placed individually on the production line, thus improving packaging efficiency. By equipping this machine with the front end of an automatic tray loading machine, the two machines can be connected and used in conjunction to complete a fully automated packaging production process.

[0003] The basic structure of the tray separating machine is as described in the prior art. Application number: CN202010399531.8, patent title: A tray separating machine, which includes a frame, a pushing mechanism, a tooth separation mechanism, a suction mechanism, and a tray conveying device. The pushing mechanism includes an upper platform on the frame, a groove along the pushing direction on the upper platform, a pushing frame movably disposed within the groove, a pushing plate extending from the upper part of the pushing frame into the groove, a guide rail at the bottom of the upper platform along the pushing direction, and a traction mechanism on the frame for pulling the pushing frame along the groove towards the tooth separation mechanism. The tooth separation mechanism is located at the end of the upper platform, the suction mechanism is located on the frame corresponding to the tooth separation mechanism, and the tray conveying device is located on the frame directly below the suction mechanism. An arc-shaped guide plate is provided on the frame between the upper platform and the tray conveying device, with the lower end of the arc-shaped guide plate connected to the tray conveying device. This design has the advantages of good suction effect, stable suction, stable pushing force, and no need for an additional power source. We understand that the tray sorting machine has a tray conveying device that transports stacks of plastic trays, and a suction head that generates negative pressure through a cylinder to suck up the trays one by one.

[0004] The fully automatic tray sorting machine we use, model FT-150, with the above conventional structure, requires the operator to manually hold the trays at the front end of the machine after they have finished loading, so that the forward trays can reach the suction cups in a stable stacked state for sorting. This increases the operator's workload, reduces the degree of automation, and the manual operation affects production efficiency.

[0005] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a pressing device for a tray-splitting machine. Utility Model Content

[0006] The purpose of this invention is to provide a pressing device for a tray-splitting machine to solve the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model discloses a pressing device for a tray sorting machine, comprising a tray conveying device and a suction cylinder on the main frame of the tray sorting machine. The suction cylinder has an adsorption head capable of generating negative pressure to adsorb plastic trays. The tray conveying device is used to convey stacked plastic trays toward the adsorption head. A gate-shaped bracket is fixedly connected above the tray conveying device on the main frame of the tray sorting machine. A support frame is connected to the top of the gate-shaped bracket. A support plate is provided on one side of the support frame above the tray conveying device. A distributing cylinder is provided on the support plate. A pressure plate is fixedly connected to the telescopic end of the distributing cylinder to press down on the plastic trays.

[0009] The suction cup cylinder and the air distribution cylinder share the same compressed air source.

[0010] Furthermore, the support plate has vertically formed strip-shaped assembly holes, and two sets of bolts are horizontally connected on the cylinder to pass through the strip-shaped assembly holes and be fastened together with nuts.

[0011] Furthermore, the lower surface of the pressure plate is covered with a silicone sheet.

[0012] Furthermore, the compressed air source for the suction cup cylinder is supplied via a main air pipe.

[0013] Furthermore, the portion of the air distribution cylinder into which the compressed air source enters is connected to an air distribution pipe, and a three-way connector is provided on the main air pipe to connect to the air distribution pipe so that the compressed air source can be simultaneously delivered to the air distribution cylinder through the air distribution pipe.

[0014] In the above technical solution, the pressing device for a tray-separating machine provided by this utility model has the following beneficial effects:

[0015] This device uses a separate air distribution cylinder to control the pressure plate to press down on the plastic tray, replacing the manual operation of stabilizing the plastic tray. The suction cup cylinder and the air distribution cylinder share the same compressed air source, allowing them to work simultaneously. As the pressure plate stabilizes the plastic tray, the suction head carries one tray away. Once the tray is carried away, the suction head retracts, and the pressure plate controlled by the air distribution cylinder retracts, allowing the plastic tray to continue moving forward and repeating the above operation. This eliminates the need for manual operation after the tray is loaded, resulting in a higher degree of automation and improved production efficiency. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1 A tray-pressing device for a tray-splitting machine includes a tray conveying device 1 and a suction cylinder 2 on the main frame of the tray-splitting machine. The suction cylinder 2 has a suction head 3 capable of generating negative pressure to adsorb plastic trays. The tray conveying device 1 conveys stacked plastic trays toward the suction head 3. After the plastic trays reach the working position of the suction head 3 on the suction cylinder 2, the suction cylinder 2 pushes the suction head 3 to the plastic tray to adsorb the plastic tray and removes one suction head to complete the work. A portal frame 4 is fixedly connected above the tray conveying device 1 on the main frame of the tray-splitting machine. A support frame 5 is connected to the top of the portal frame 4. One side of the support frame 5 is located on the tray conveying device 1. A support plate 6 is installed above the delivery device 1. Supported by the portal frame 4, it does not obstruct the forward movement of the plastic tray. The portal frame 4 then supports the support frame 5, so that the support frame 5 supports the support plate 6 above the plastic tray. An air distribution cylinder 7 is installed on the support plate 6. The support plate 6 supports the air distribution cylinder 7 above the plastic tray. A pressure plate 8 is fixedly connected to the telescopic end of the air distribution cylinder 7 to press down on the plastic tray. In order for the pressure plate 8 to press on the plastic tray close to the working position of the adsorption head 3, the pressure plate 8 is located below the crossbeam of the portal frame 4. The pressure of the pressure plate 8 on the plastic tray only serves to stabilize the plastic tray and does not affect the adsorption head 3 from adsorbing and removing a plastic tray.

[0022] The suction cylinder 2 and the air distribution cylinder 7 share the same compressed air source, so that the suction cylinder 2 and the air distribution cylinder 7 work at the same time. In this way, the pressure plate 8 stabilizes the plastic tray while the suction head 3 takes away a plastic tray. As the plastic tray is taken away, the suction head 3 is withdrawn and the pressure plate 8 controlled by the air distribution cylinder 7 is withdrawn, so that the plastic tray continues to move forward and repeats the above operation.

[0023] Furthermore, the support plate 6 has a vertically formed strip-shaped mounting hole 9. Two sets of bolts 10 are horizontally connected to the distribution cylinder 7, passing through the strip-shaped mounting hole 9 and being fastened with nuts. The support plate 6 and the distribution cylinder 7 are in an adjustable fixed connection relationship. The idle position of the distribution cylinder 7 is adjusted by vertically connecting the bolts 10, allowing the bolts 10 to be adjusted within the strip-shaped mounting hole 9, thereby adjusting the height of the distribution cylinder 7. Finally, the connection is tightened with nuts so that the distribution cylinder 7 can operate at a suitable height.

[0024] Furthermore, the lower surface of the pressure plate 8 is covered with a silicone plate 11 so that the pressure plate 8 contacts the plastic tray through the silicone plate 11, thus avoiding damage to the plastic tray due to rigid contact.

[0025] Furthermore, the compressed air source of the suction cylinder 2 is delivered through the main air pipe 12, which in turn drives the extension and retraction of the extension end of the suction cylinder 2.

[0026] Furthermore, the part of the air distribution cylinder 7 that receives the compressed air source is connected to an air distribution pipe 13. A three-way connector 14 is provided on the main air pipe 12 to connect to the air distribution pipe 13 so that the compressed air source can be simultaneously delivered to the air distribution cylinder 7 through the air distribution pipe 13. That is, the compressed air source delivered by the main air pipe 12 is diverted by the three-way connector 14 and simultaneously reaches the suction cup cylinder 2 and the air distribution cylinder 7 through the main air pipe 12 and the air distribution pipe 13, thereby enabling the suction cup cylinder 2 and the air distribution cylinder 7 to extend and retract simultaneously.

[0027] In summary, this device uses a separate air distribution cylinder to control the pressure plate to press down on the plastic tray, thus replacing the manual operation of stabilizing the plastic tray. Furthermore, the suction cup cylinder and the air distribution cylinder share the same compressed air source, allowing them to operate simultaneously. As the pressure plate stabilizes the plastic tray, the suction head carries one tray away. Simultaneously, the suction head retracts, and the pressure plate controlled by the air distribution cylinder retracts, allowing the plastic tray to continue moving forward and repeating the above operation. This eliminates the need for manual operation after loading, resulting in a higher degree of automation and improved production efficiency.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
