Description

Technical Field

[0001] This utility model relates to the field of raw material mixing, and more specifically to an environmentally friendly plastic cup raw material mixing device. Background Technology

[0002] The commonly used raw material for eco-friendly plastic cups is polylactic acid (PLA) granules, made from plant resources such as corn and cassava. They are generally transparent or semi-transparent and granular. Plastic cups made from PLA are biodegradable in the natural environment, making them suitable for scenarios with high environmental requirements, such as disposable cups used in high-end organic beverage shops and environmentally themed events. Additives, such as plasticizers, antioxidants, and heat stabilizers, are added to the PLA granules. Plasticizers improve the flexibility and processing performance of PLA; antioxidants and heat stabilizers are present in smaller amounts to prevent oxidation and thermal degradation of PLA during processing and use. In processing eco-friendly plastic cups, the additives and PLA granules are mixed, the PLA granules are melted, and then the plastic cups are made from the PLA granules. However, in existing technologies, the bottom of the container where the additives and PLA granules are mixed has a right angle. After mixing, material residue easily accumulates at the right angle, making it difficult to wipe clean with a cloth. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides an environmentally friendly plastic cup raw material mixing device. Its advantages are that there are no right angles at the bottom of the mixing container, and after the plastic cup raw materials are mixed, there is not much raw material residue, and it is easy to wipe and clean with a cloth.

[0004] An environmentally friendly plastic cup raw material mixing device includes a mixing container, which is a cylindrical body with a rounded chamfer on the lower inner edge and a cover that can be opened or closed.

[0005] A control handle is fixed to the mixing container, and a grip is fixed to the front of the control handle.

[0006] A slider is fixed to one side of the cover plate, and the slider is slidably connected to the control handle.

[0007] A control lever is fixed on the slider.

[0008] The handle has multiple axial anti-slip ridges integrally formed.

[0009] The handle has multiple axial anti-slip ridges integrally formed, and grooves are formed between the multiple axial anti-slip ridges, with the control rod located in the grooves.

[0010] A ring is fixed to the end of the control lever.

[0011] The control handle is provided with a straight edge, and the slider is slidably connected to the straight edge.

[0012] One side of the cover plate is rotatably connected to the mixing container, and the other side of the cover plate is connected to a spring piece that can abut against the inner wall of the mixing container. The spring piece and the inner wall of the mixing container can generate frictional resistance to prevent the cover plate from rotating open. When an external force pushes the cover plate to drive it to rotate open, it overcomes the frictional resistance between the spring piece and the inner wall of the mixing container, causing the spring piece to slide out from the inner wall of the mixing container.

[0013] The spring is L-shaped, and the L-shaped spring can abut against the inner wall of the mixing container to generate frictional resistance and prevent the cover from rotating open. Attached Figure Description

[0021] like Figure 1 As shown, this example demonstrates how mixing container 1 can be easily wiped clean with a cloth.

[0022] An environmentally friendly plastic cup raw material mixing device includes a mixing container 1, which is a cylindrical body. The lower inner edge of the mixing container 1 has an integrally formed rounded chamfer. After the plastic particles and additives are poured into the mixing container 1, the plastic particles and additives can be mixed by shaking the mixing container 1 by hand. After the mixing is completed, the plastic particles are poured out. The rounded chamfer on the lower inner edge of the mixing container 1 is easy to wipe and clean with a cloth, which is easier to wipe and clean with a cloth than the right angle of traditional containers.

[0023] like Figure 1 As shown, this example demonstrates how to easily mix the raw materials for environmentally friendly plastic cups.

[0024] Because the front of the mixing container 1 is welded with a cylindrical control handle 8, the control handle 8 is easy to hold and allows people to control the shaking of the mixing container 1 by hand, thereby facilitating the mixing of the environmentally friendly plastic cup raw materials.

[0025] like Figure 1 As shown, this example can achieve the effect of making the grip of the control handle 8 more comfortable.

[0026] Because a cylindrical control handle 8 is welded to the front of the mixing container 1, and a handle 6 is sleeved on the front of the control handle 8, the handle 6 is a hollow cylinder, and the handle 6 is interference-fitted onto the control handle 8. The handle 6 is thicker than the control handle 8, making it easier to grip and more comfortable to hold the control handle 8.

[0027] like Figure 1-2 As shown, this example can prevent slippage when holding handle 6.

[0028] Because a cylindrical control handle 8 is welded to the front of the mixing container 1, and a handle 6 is sleeved on the front of the control handle 8, and multiple axial anti-slip ridges 7 are integrally formed on the handle 6, the multiple axial anti-slip ridges 7 are integrally formed on the handle 6, which increases the friction between the palm and the handle 6 and prevents slipping when holding the handle 6. The handle 6 can be made of rubber or polyethylene to improve the anti-slip effect.

[0029] like Figure 1-2 As shown, this example can achieve the effect of preventing raw materials from flying out of the mixing container 1 when the mixing container 1 is shaken.

[0030] Since the mixing container 1 is covered with a cover plate 2 that can be opened and closed, after the raw materials are poured into the mixing container 1, the cover plate 2 is placed on the mixing container 1. The cover plate 2 can be opened and closed by sliding or by rotating. When the cover plate is slid closed, it can fit tightly with the mixing container 1, forming a good sealing effect. When the cover plate is rotated open and closed, the rotational opening method is usually based on simple mechanical structures such as pivots and hinges. This structure is simpler than the track, slider and other components of the sliding opening method, has a lower manufacturing cost, and is less prone to failure. After the cover plate 2 is closed, it can prevent the raw materials from flying out of the mixing container 1 when the mixing container 1 shakes.

[0031] like Figure 1-3 As shown, this example demonstrates how to control the opening and closing of cover 2.

[0032] Since a slider 3 is integrally formed on one side of the cover plate 2, the slider 3 is slidably connected to the control handle 8. The slider 3 is provided with a through hole corresponding to the control handle 8. The slider 3 is inserted into the control handle 8 through the gap of the through hole to achieve a sliding connection. When the control handle 8 slides, the slider 3 drives the cover plate 2 to slide on the upper side of the mixing container 1, thereby controlling the opening and closing of the cover plate 2.

[0033] like Figure 1-3 As shown, this example can achieve the effect of controlling the cover plate 2 to slide on the upper side of the mixing container 1.

[0034] Since there are two control levers 4 welded on the slider 3, by holding the two control levers 4 with your fingers, you can easily control the slider 3 to slide on the control handle 8, and thus control the cover plate 2 to slide on the upper side of the mixing container 1.

[0035] like Figure 2-3 As shown, this example can achieve the effect of preventing raw materials from flying out.

[0036] Because the handle 6 has multiple axial anti-slip ridges 7 integrally formed, and grooves are formed between the multiple axial anti-slip ridges 7, the two control rods 4 fit into the grooves on the handle 6. When a person holds the handle 6, they can press on the two control rods 4 at the same time, thereby fixing the two control rods 4, fixing the slider 3, and fixing the cover plate 2 to the mixing container 1. When the handle 6 is held and the mixing container 1 is shaken, the cover plate 2 can be fixed to the mixing container 1 by the gripping force of the hand, preventing the raw materials from flying out.

[0037] like Figure 1-2 As shown, this example demonstrates how to conveniently store an eco-friendly plastic cup mixing device by hanging it on a hook in a cabinet using a rope.

[0038] The ends of the two control levers 4 are integrally formed with rings 5, which can be used to easily tie ropes, and then conveniently hang the environmentally friendly plastic cup raw material mixing device on the hook in the cabinet for storage.

[0039] like Figure 1-2 As shown, this example can achieve a more stable effect when the cover plate 2 is placed on the mixing container 1.

[0040] Because the control handle 8 has a straight ridge 9 integrally formed, and the cross-section of the straight ridge 9 is rectangular, the slider 3 is provided with a slot corresponding to the shape of the straight ridge 9. The slider 3 is inserted into the straight ridge 9 through the slot gap fit to complete the sliding connection. The straight ridge 9 makes the slider 3 more stable when sliding on the straight ridge 9, so that the slider 3 cannot rotate in the circumferential direction of the control handle 8, so that the cover plate 2 is not easy to shake, and the cover plate 2 is more stable when covering the mixing container 1.

[0041] like Figure 4-5 As shown, this example can prevent the cover plate 2 from rotating open.

[0042] Since one side of the cover plate 2 is rotatably connected to the mixing container 1 via a hinge, and the other side of the cover plate 2 is connected to a spring piece 10 that can abut against the inner wall of the mixing container 1 via a rivet, the spring piece 10 and the inner wall of the mixing container 1 can generate resistance to prevent the cover plate 2 from rotating open. The spring piece 10 presses against the inner wall of the mixing container 1 with elasticity, generating frictional resistance to prevent the cover plate 2 from rotating open. When the cover plate 2 is pushed upward by hand to drive the cover plate 2 to rotate open, the frictional force between the spring piece 10 and the inner wall of the mixing container 1 is overcome, causing the spring piece 10 to slide out from the inner wall of the mixing container 1, thereby rotating the cover plate 2 open.

[0043] like Figure 4-5 As shown, this example can achieve the effect of preventing the cover plate 2 from rotating open by using the L-shaped spring 10.

[0044] Because one side of the cover plate 2 is hinged to the mixing container 1, and the other side of the cover plate 2 is connected by rivets to an L-shaped spring piece 10 that can abut against the inner wall of the mixing container 1, the L-shaped spring piece 10 can easily abut against the inner wall of the mixing container 1 with elastic force. The L-shaped spring piece 10 and the inner wall of the mixing container 1 can generate resistance to prevent the cover plate 2 from rotating open. The L-shaped spring piece 10 presses against the inner wall of the mixing container 1 with elastic force, generating frictional resistance to prevent the cover plate 2 from rotating open. When the cover plate 2 is pushed upward by hand to drive the cover plate 2 to rotate open, the friction between the spring piece 10 and the inner wall of the mixing container 1 is overcome, so that the L-shaped spring piece 10 slides out from the inner wall of the mixing container 1, thereby rotating the cover plate 2 open.

[0045] In addition, the spring 10 can also be connected to the outer surface of the non-rotating shaft side of the cover plate 2 by rivets or screws, so that the spring 10 and the outer wall of the mixing container 1 can generate resistance to prevent the cover plate 2 from rotating open. The spring 10 presses against the outer wall of the mixing container 1 with elasticity to generate frictional resistance and prevent the cover plate 2 from rotating open. When the cover plate 2 is pushed upward by hand to drive the cover plate 2 to rotate open, the friction between the spring 10 and the outer wall of the mixing container 1 is overcome, so that the spring 10 slides out from the outer wall of the mixing container 1, thereby rotating the cover plate 2 open.

[0046] Furthermore, the spring 10 connected to the outer surface of the non-rotating shaft side of the cover plate 2 can also be L-shaped, so that the bottom of the L-shaped spring 10 hooks onto the bottom of the mixing container 1, thereby achieving a more stable connection effect and preventing the cover plate 2 from rotating open; when the L-shaped spring 10 is pushed outward by hand, the bottom of the spring 10 is separated from the bottom of the mixing container 1, and then the cover plate 2 can be rotated open by hand.

[0047] Furthermore, each spring 10 can be wrapped with a layer of rubber to increase the frictional resistance between the spring 10 and the mixing container 1, thereby preventing the cover plate 2 from rotating open.
