Description

Technical Field

[0001] This utility model relates to the field of shaping equipment technology, and in particular to a biodegradable food tray vacuum adsorption shaping device. Background Technology

[0002] Biodegradable food trays are environmentally friendly food containers that can decompose into harmless substances (such as carbon dioxide and water) through the action of microorganisms in the natural environment. Vacuum adsorption shaping equipment is an automated molding machine designed specifically for environmentally friendly materials and is mainly used to produce food trays made of biodegradable materials.

[0003] Existing biodegradable food tray vacuum adsorption shaping equipment involves fixing the mold to the machine body, placing the tray sheet on the mold, and then using a cylinder to drive the heating chamber to close with the machine body, enveloping the mold and tray sheet. The tray sheet is heated and softened to 120-200℃ by an electric heating furnace inside the heating chamber. Then, a vacuum pump inside the machine body generates negative pressure, causing the sheet to adhere to the mold surface and form. After forming, the tray is cooled, completing the shaping process.

[0004] However, because the tray adheres tightly to the mold surface after adsorption and shaping, the operating space for personnel is limited, making it inconvenient to pick up materials and affecting the efficiency of material retrieval. Utility Model Content

[0005] The technical problem this invention aims to solve is that the tray adheres tightly to the mold surface after adsorption and shaping, resulting in limited operating space for personnel, making material retrieval inconvenient and affecting the efficiency of material retrieval.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a biodegradable food tray vacuum adsorption shaping device, comprising: a body, which is placed on the ground and used to control and support the overall components; a heating chamber, which is set on the body and used to heat the tray material; a mold, which is set on the body and used to shape the tray material; and a material picking device, which is set on the body, wherein personnel use the material picking device to separate the shaped tray from the mold.

[0007] Preferably, the material handling device includes: a frame, which is detachably mounted on the machine body via a connecting assembly; a support, the surface of which is slidably connected to the inner wall of the frame, wherein a first electric telescopic rod is fixedly connected to one side of the support; a suction cup, which is fixedly connected to the moving end of the first electric telescopic rod, wherein the first electric telescopic rod drives the suction cup to move up and down, wherein a sealing strip is fixedly connected to the side of the suction cup near the machine body; and an air cylinder, which is fixedly connected to the support, wherein the air cylinder and the suction cup are connected via a flexible hose, wherein a piston plate is slidably connected to the inner wall of the air cylinder, wherein the piston plate is driven by a second electric telescopic rod, wherein the second electric telescopic rod is fixedly connected to the support.

[0008] The effects achieved by the above components are as follows: By setting up the material handling device, the support is first manually moved, causing it to slide along the inside of the frame, which in turn moves the suction cup. When the suction cup moves to the position directly above the mold, the first electric telescopic rod is activated, causing the suction cup to move in the opposite direction towards the mold. When the suction cup moves to the position where it is in contact with the surface of the tray on the mold, the second electric telescopic rod is activated, causing the piston plate to move along the inside of the air cylinder away from the support. During the movement, the piston plate draws air from inside the suction cup through the hose, creating a negative pressure inside the suction cup and generating suction to tightly adhere the tray. Then, the first electric telescopic rod is used to move the tray away from the mold through the suction cup, separating the tray from the mold. This achieves rapid demolding and material handling of the tray, reducing the limited operating space and inconvenience of material handling caused by the tray being tightly attached to the mold surface after adsorption and shaping. It also reduces direct contact between the hands and the tray, reducing the risk of burns.

[0009] Preferably, a support rod is fixedly connected to one side of the frame, wherein the support rod is fixed at an angle.

[0010] The effect achieved by the above components is that by setting up support rods, the frame can be further supported, reducing the swaying of the frame during use and affecting the stability of material handling.

[0011] Preferably, a limiting plate is fixedly connected to the side of the support near the frame, wherein the surface of the limiting plate is larger than the inner wall of the frame, and the surface of the limiting plate is in contact with the surface of the frame.

[0012] The effect achieved by the above components is that by setting a limiting plate, the limiting plate can fit against the frame surface to limit the support, reducing the tilting of the support during the sliding process.

[0013] Preferably, a handle is fixedly connected to one side of the support, wherein the inner side of the handle is provided with multiple anti-slip protrusions.

[0014] The effect achieved by the above components is that by setting handles, a point of leverage can be provided for personnel, allowing them to move the support by manually moving the handles, thus improving the convenience of manually moving the support.

[0015] Preferably, the connecting assembly includes a rectangular tube fixed to the machine body, wherein bolts are threaded onto the inner wall of the rectangular tube, and the frame is placed inside the rectangular tube and fixed by bolts.

[0016] The effect achieved by the above components is as follows: by setting the connecting components, the frame is first manually moved to the position of being inserted into the rectangular tube, so that the inner wall of the hole on the rectangular tube coincides with the inner wall of the hole on the frame. At this time, the bolts are manually screwed into the rectangular tube and the frame to fix the frame, thereby achieving the assembly and fixation between the frame and the machine body. At the same time, the frame can be disassembled later, improving the flexibility of use and the convenience of maintenance of the material handling device.

[0017] Preferably, the surface of the bolt is fixedly connected with a plurality of anti-slip strips, wherein the anti-slip strips are arranged at equal intervals.

[0018] The effect achieved by the above components is that by setting anti-slip strips, the friction between the hand and the bolt surface can be increased, reducing the chance of slipping when manually turning the bolt.

[0019] Preferably, it further includes: a cooling assembly, the cooling assembly comprising: a fan duct fixedly connected to a support, wherein a fan is fixedly connected to one side of the fan duct; and a perforated plate fixedly connected to the side of the fan duct away from the fan, wherein the perforated plate intercepts large-volume debris from the outside.

[0020] The effect achieved by the above components is as follows: by setting up the cooling components, the fan is first started to deliver airflow into the air duct, so that the airflow is discharged through the air duct and blown onto the surface of the pallet, accelerating the airflow speed on the surface of the pallet, increasing the heat dissipation speed of the pallet surface, thereby achieving auxiliary cooling of the pallet, reducing the residual heat on the surface of the pallet, which could cause personnel to burn their hands when picking up materials, and improving the cooling and shaping efficiency of the pallet.

[0021] The beneficial effects of this utility model are:

[0022] By setting up a material handling device, personnel can quickly demold the tray, reducing the situation where the tray is tightly attached to the mold surface after adsorption and shaping, resulting in limited operating space and inconvenience in material handling. At the same time, it reduces direct contact between the hands and the tray, reducing the risk of burns. Attached Figure Description

[0031] Figure 1-4 The illustrated biodegradable food tray vacuum adsorption shaping device includes: a body 1, which is placed on the ground and used to control and support the overall components; a heating chamber 2, which is disposed on the body 1 and used to heat the tray material; a mold 3, which is disposed on the body 1 and used to shape the tray material; and a material picking device 4, which is disposed on the body 1, wherein personnel use the material picking device 4 to separate the shaped tray from the mold 3.

By setting up the material handling device 4, the support 43 is first manually moved, causing the support 43 to slide along the inside of the frame 41, thereby causing the support 43 to drive the suction cup 46 to move. When the suction cup 46 moves to the mold 3, When directly above the mold 3, the first electric telescopic rod 45 is activated, causing the suction cup 46 to move in the opposite direction towards the mold 3. When the suction cup 46 moves to a position where it is in contact with the tray surface on the mold 3, the second electric telescopic rod 48 is activated, causing the piston plate 49 to move along the inside of the air cylinder 47 away from the support 43. During the movement, the piston plate 49 draws air from inside the suction cup 46 through the hose, creating a negative pressure inside the suction cup 46 and generating suction to tightly adhere the tray. Then, the first electric telescopic rod 45 is used again to move the tray away from the mold 3 through the suction cup 46, separating the tray from the mold 3. This achieves rapid demolding and material removal of the tray, reducing the limited operating space and inconvenience of material removal caused by the tray being tightly attached to the surface of the mold 3 after adsorption and shaping. It also reduces direct contact between the hands and the tray, reducing the risk of burns.

[0033] Figure 2 , Figure 3 and Figure 4 A support rod 42 is fixedly connected to one side of the frame 41 shown. The support rod 42 is fixed at an angle. By setting the support rod 42, the frame 41 can be auxiliaryly supported, reducing the shaking of the frame 41 under force during use and affecting the stability of material handling. A limit plate 44 is fixedly connected to the side of the support 43 near the frame 41. The surface of the limit plate 44 is larger than the inner wall of the frame 41, and the surface of the limit plate 44 is in contact with the surface of the frame 41. By setting the limit plate 44, the limit plate 44 can fit against the surface of the frame 41 to limit the support 43, reducing the tilting of the support during sliding.

[0034] Figure 2 , Figure 3 and Figure 4A handle 410 is fixedly connected to one side of the support 43 shown. The inner side of the handle 410 is provided with multiple anti-slip protrusions. By setting the handle 410, a point of leverage can be provided for personnel, so that personnel can manually move the handle 410 to drive the support 43 to move, thereby improving the convenience of manually moving the support 43.

[0035] Figure 2 The connecting component 5 shown includes a rectangular tube 51, which is fixed to the machine body 1. Bolts 52 are threaded onto the inner wall of the rectangular tube 51. The frame 41 is placed inside the rectangular tube 51 and fixed by the bolts 52. By setting the connecting component 5, the frame 41 is first manually moved to the position of being inserted into the rectangular tube 51, so that the inner wall of the hole on the rectangular tube 51 coincides with the inner wall of the hole on the frame 41. At this time, the bolts 52 are manually screwed into the positions inside the rectangular tube 51 and the frame 41 to fix the frame 41, thereby achieving the assembly and fixation between the frame 41 and the machine body 1. At the same time, the frame 41 can be disassembled later, improving the flexibility of use and the convenience of maintenance of the material handling device 4. Multiple anti-slip strips 53 are fixedly connected to the surface of the bolts 52. The anti-slip strips 53 are arranged at equal intervals. By setting the anti-slip strips 53, the friction between the hand and the surface of the bolts 52 can be increased, reducing the possibility of slippage when manually turning the bolts 52.

[0036] Figure 3 and Figure 4 The system also includes a cooling assembly 6, which comprises: a duct 62 fixed to the support 43, wherein a fan 61 is fixed to one side of the duct 62; and a perforated plate 63 fixed to the side of the duct 62 away from the fan 61. The perforated plate 63 intercepts large debris from the outside. By setting up the cooling assembly 6, the fan 61 is first started to deliver airflow into the duct 62, so that the airflow is discharged through the duct 62 and blown onto the surface of the pallet, accelerating the airflow speed on the surface of the pallet and increasing the heat dissipation speed of the pallet surface, thereby achieving auxiliary cooling of the pallet, reducing the residual heat on the pallet surface, which could cause burns to the hands of personnel when handling materials, and improving the cooling and shaping efficiency of the pallet.

[0037] Working principle: During processing, mold 3 is fixedly installed on machine body 1, and then the pallet sheet is placed on mold 3. Then, the heating chamber 2 is driven by a cylinder to close with machine body 1, enclosing mold 3 and pallet sheet inside. The pallet sheet is heated and softened to 120-200℃ by the electric heating furnace inside heating chamber 2. Then, the vacuum pump inside machine body 1 generates negative pressure, causing the sheet to adhere to the surface of mold 3 and form. After forming, it is allowed to cool, completing the shaping process of the pallet.

[0038] First, manually move the frame 41 to the position where it is inserted into the rectangular tube 51, so that the inner wall of the hole on the rectangular tube 51 coincides with the inner wall of the hole on the frame 41. Then, manually screw the bolt 52 into the rectangular tube 51 and the frame 41 to fix the frame 41, thereby achieving the assembly and fixation between the frame 41 and the machine body 1. Then, manually move the support 43 so that the support 43 slides along the inside of the frame 41, causing the support 43 to drive the suction cup 46 to move. When the suction cup 46 moves to the position directly above the mold 3, activate the first electric telescopic rod 45, so that the first electric telescopic rod 45 drives the suction cup 46 closer to the mold 3. When the mold 3 moves in the reverse direction, and the suction cup 46 moves to the position where it fits against the surface of the tray on the mold 3, the second electric telescopic rod 48 is activated. This causes the second electric telescopic rod 48 to drive the piston plate 49 to move along the inside of the air cylinder 47 away from the support 43. During the movement, the piston plate 49 draws air from the inside of the suction cup 46 through the hose, creating a negative pressure inside the suction cup 46 and generating suction to tightly adhere the tray. Then, the first electric telescopic rod 45 is used to drive the tray away from the mold 3 through the suction cup 46, separating the tray from the mold 3, thereby achieving rapid demolding and material removal of the tray.

[0039] At the same time, the fan 61 is started to deliver airflow into the air duct 62, so that the airflow is discharged through the air duct 62 and blown onto the surface of the tray, accelerating the airflow speed on the surface of the tray and increasing the heat dissipation speed of the tray surface, thereby achieving auxiliary cooling of the tray.
