Technical Field

[0001] This utility model relates to the field of laminating machines, and in particular to a laminating machine receiving device. Background Technology

[0002] Plastic sealing involves bonding the items to be sealed within a polyester film coated with hot melt adhesive using a laminating machine. Because the process is carried out under certain pressure and high temperature, and uses high-quality polyester film and highly transparent hot melt adhesive, it not only ensures that the sealed items are not damaged at room temperature, but also enhances the visual appeal of the items.

[0003] According to the prior art, "A material receiving device for a plastic sealing machine" with the announcement number "CN218022551U", when the material needs to be transferred, the device can prevent the material from being damaged by bumps and vibrations during the transfer of the trolley body through springs and buffers. However, when the material is picked up, if the impact of the material falling is large, the single buffering effect may be ineffective, resulting in the material shaking after thermoforming.

[0004] Therefore, a material receiving device for a plastic sealing machine is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a material receiving device for a plastic sealing machine to solve the above-mentioned problems. This device improves the situation where the impact of falling material is large, which may lead to poor single buffering effect and cause the material to shake after thermoforming.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a material receiving device for a sealing machine, comprising: a guide frame, the upper end of which is fixedly connected to two side strips; a buffer mechanism, which is installed at the end of the guide frame; wherein, the buffer mechanism includes a bracket installed at the end of the guide frame, a baffle is fixedly connected to the side of the bracket away from the guide frame, two side grooves are opened on both sides of the bracket, a bottom buffer assembly is provided on the inner bottom wall of the bracket, and a contact buffer assembly is provided above the bottom buffer assembly.

[0007] Preferably, the contact buffer assembly includes a support plate slidably connected to the inner wall of the bracket. A round rod is fixedly connected to the lower end of the support plate, and a base plate is fixedly connected to the lower end of the round rod. A spring is sleeved on the surface of the round rod. The falling support plate compresses the spring, and the lower end of the spring is fixedly connected to the upper end of the fixed plate.

[0008] Preferably, the bottom buffer assembly includes multiple circular tubes fixedly connected to the inner bottom wall of the bracket. The multiple circular tubes are arranged in an array. A fixing plate is fixedly connected to the upper end of each circular tube, and a side groove is formed on one side of each circular tube. The bottom plate is located below the fixing plate, and when the support plate moves downward, it drives the bottom plate to move downward synchronously.

[0009] Preferably, two guide strips are fixedly connected to both ends of the supporting plate, and the guide strips are slidably connected to the inner wall of the adjacent side groove. When the material is above the supporting plate, the supporting plate moves downward with the assistance of the four guide strips and the side groove, thus buffering the falling material again.

[0010] Preferably, a cone head is fixedly connected to the lower end of the base plate, and a bottom hole is provided on the lower end of the base plate near the adjacent cone head.

[0011] Preferably, an airbag is fixedly connected to the lower end of the fixing plate, and the airbag is fixedly connected to the inner bottom wall of the bracket. By moving the bottom plate downward, the airbag is compressed to form a buffer.

[0012] Preferably, a connector is embedded in one side of the airbag, and an air guide is fixedly connected to the inner wall of the connector. This allows the gas inside the airbag to be slowly discharged to the outside through the air guide and the connector.

[0013] Preferably, a soft rubber telescopic tube is fixedly connected to the inner top wall of the airbag, and the soft rubber telescopic tube is sleeved on the outside of the round tube.

[0014] Preferably, a plurality of buffer rubber rods are fixedly connected to the upper end of the support plate, and the plurality of buffer rubber rods are arranged in an array along the upper end of the support plate.

[0015] Preferably, the other end of the air guide head penetrates the airbag, and the surface of the air guide head is mounted on one side of the bracket.

[0016] The beneficial effects of this utility model are:

[0017] 1. The above-mentioned material receiving device of the sealing machine can perform preliminary buffering operation on the material above the support plate under the action of the contact buffer component. The device works with the buffer rubber rod and the spring to achieve the effect of buffering the falling material when the material is above the support plate and contacts the buffer rubber rod. The falling support plate squeezes the spring, and the lower end of the spring is fixedly connected to the upper end of the fixed plate. Under the action of the elastic potential energy of the spring, the material is buffered for a second time, reducing the shaking of the material after thermoforming.

[0018] 2. By setting a bottom buffer component, the device can buffer the falling support plate. The device moves the bottom plate down and squeezes the air bag, so that the gas inside the air bag is slowly discharged to the outside through the set air guide head and connector, which reduces the shaking of the material during the falling process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In practical implementation: such as Figure 1-5As shown, a material receiving device for a sealing machine includes: a guide frame 1, with two side strips 2 fixedly connected to the upper end of the guide frame 1; a buffer mechanism 3 installed at the end of the guide frame 1; wherein, the buffer mechanism 3 includes a bracket 33 installed at the end of the guide frame 1, a baffle 34 fixedly connected to the side of the bracket 33 away from the guide frame 1, two side grooves 331 opened on both sides of the bracket 33, a bottom buffer assembly 32 provided on the inner bottom wall of the bracket 33, and a contact buffer assembly 31 provided above the bottom buffer assembly 32;

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the contact buffer assembly 31 includes a support plate 311 slidably connected to the inner wall of the bracket 33. Multiple buffer rubber rods 312 are fixedly connected to the upper end of the support plate 311. The multiple buffer rubber rods 312 are arranged in an array along the upper end of the support plate 311. A round rod 313 is fixedly connected to the lower end of the support plate 311. A base plate 314 is fixedly connected to the lower end of the round rod 313. A spring 315 is sleeved on the surface of the round rod 313. Two guide strips 316 are fixedly connected to both ends of the support plate 311. The guide strips 316 are slidably connected to the inner wall of the adjacent side groove 331. A cone head 318 is fixedly connected to the lower end of the base plate 314. A bottom hole 317 is opened at the lower end of the base plate 314 near the adjacent cone head 318.

[0028] The device mitigates the impact of falling objects by using the inclined slope of the guide frame 1. When the device comes into contact with the goods, the buffer rubber rod 312 at the upper end of the support plate 311 provides initial cushioning. When the material is above the support plate 311, the support plate 311 moves downward with the cooperation of four guide bars 316 and side grooves 331, which further cushions the falling material. The falling support plate 311 compresses the spring 315, the lower end of which is fixedly connected to the upper end of the fixed plate 322. The spring 315 keeps the support plate 311 away from the fixed plate 322 under normal conditions.

[0029] like Figures 2-5 As shown, the bottom buffer assembly 32 includes multiple round tubes 321 fixedly connected to the inner bottom wall of the bracket 33. A fixing plate 322 is fixedly connected to the upper end of the round tube 321. A side groove 323 is opened on one side of the round tube 321. An airbag 324 is fixedly connected to the lower end of the fixing plate 322. The airbag 324 is fixedly connected to the inner bottom wall of the bracket 33. A connector 327 is embedded in one side of the airbag 324. An air guide head 326 is fixedly connected to one side of the connector 327. The other end of the air guide head 326 extends to the outside of the bracket 33. A soft rubber telescopic tube 325 is fixedly connected to the inner top wall of the airbag 324. The soft rubber telescopic tube 325 is sleeved on the outside of the round tube 321.

[0030] The base plate 314 is located at the lower end of the fixed plate 322, and when the support plate 311 moves downward, it drives the base plate 314 to move downward synchronously. As the base plate 314 moves downward, it compresses the air bladder 324, which in turn causes the gas inside the air bladder 324 to be slowly discharged to the outside through the air guide head 326 and the connector head 327. This reduces the shaking of the material during the falling process and reduces the possibility of material breakage due to bumping after thermoplasticization.

[0031] In use, the goods will contact the buffer rubber rod 312 at the upper end of the support plate 311. When the material is above the support plate 311, it moves downward with the assistance of the four guide bars 316 and the side groove 331. The falling support plate 311 compresses the spring 315 and drives the bottom plate 314 to move downward below the fixed plate 322 through the round rod 313. The bottom plate 314 is located at the lower end of the fixed plate 322. When the support plate 311 moves downward, it drives the bottom plate 314 to move downward synchronously. As the bottom plate 314 moves downward, the gas inside the airbag 324 is slowly discharged to the outside through the air guide head 326 and the connector head 327, which alleviates the shaking of the material during the falling process and reduces the possibility of material breakage due to bumping after thermoforming.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
