Description

Technical Field

[0001] The invention relates to the technical field of plastic products, and in particular to a packaging bottle handle separation device. Background Art

[0002] PET packaging bottles have always been a non-mainstream product in the packaging material market, but they are an indispensable product for medium and high capacity PET bottles on the market. For example, edible oil, soy sauce, etc. are all using PET packaging bottles with handles as containers. Traditional glass bottles have the disadvantages of being fragile, heavy, high energy consumption in the process, and high transportation costs. PET packaging bottles with handles can overcome the above disadvantages. At present, glass bottles are gradually being replaced by PET packaging bottles.

[0003] In order to facilitate taking, there are two production methods. One is the front-inserted handle bottle: the handle and the embryo tube are placed in the bottle blowing mold at the same time, and the handle is tightly joined to the bottle body; the other is the rear-inserted handle bottle: the bottle body is blown first, and then the handle is combined with the bottle body.

[0004] In recent years, with the growth of market demand, the enhancement of people's energy-saving and environmental protection awareness, and the increase in human resource costs, the front-inserted handle-automatic bottle blowing machine has become one of the key research and development projects of various equipment manufacturers. However, the problem of poor production efficiency has not been solved. In the process of production, defective products are produced. When dealing with defective products, since the handles of the bottles with handles are generally made of PP material and the bottle body is made of PET material, the combination of two different materials leads to difficulties in the treatment of defective products. At present, the manufacturers of PET packaging bottles basically adopt the following treatment methods for the treatment of defective products: no separation and recycling, directly selling them to waste recyclers as waste rubber, which can save labor costs for treatment, but requires a large loss of raw material costs; or separate the handle and the PET packaging bottle body, and use manual separation to separate the handle and the bottle body, but because the handle is covered by the PET bottle body, it is relatively difficult to separate. Each worker can only handle about 2,000 to 3,000 bottles in an 8-hour working day, and the labor cost is too high. Therefore, it is particularly important to provide a device that can save labor costs when separating the handle and can separate the handle and the bottle body. Summary of the invention

[0005] The object of the present invention is to provide a packaging bottle handle separation device capable of saving labor costs, so as to solve the technical problem of high labor costs in manually separating defective handles and bottle bodies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a packaging bottle handle separation device, which is used for separating the bottle body and the handle of the packaging bottle, and the device comprises a supporting device and a separating device fixed on the supporting device; the separating device comprises a driving assembly, a conveying assembly and a limiting assembly; the driving assembly is used to drive the conveying assembly to operate; the conveying assembly is used to continuously convey the packaging bottle to the limiting assembly to realize the separation of the bottle body and the handle, a handle hanging plate is fixed on the conveying assembly, the packaging bottle is hung on the conveying assembly through the handle hanging plate, the handle hanging plate is curved, and the curved opening of the handle hanging plate faces the conveying direction of the conveyor belt; the limiting assembly comprises a fixing plate and a pressing plate fixed on the fixing plate, when the packaging bottle moves to contact the pressing plate, the pressing plate blocks the bottle body of the packaging bottle, hinders the bottle body from continuing to move, and promotes the separation of the bottle body and the handle.

[0007] Preferably, there are at least two pressing plates, the two pressing plates are parallel to each other and form an angle with the fixed plate, the spacing distance between the two pressing plates is greater than the length of the handle, and when the handle and the bottle body are transported to the pressing plate, the intersection of the pressing plate and the fixed plate first contacts the bottle body, and at this time the bottle body is stuck on the sides of the two pressing plates away from the fixed plate.

[0008] Preferably, the conveying assembly includes a conveyor belt, and the handle hanging plate is fixed on the conveyor belt.

[0009] Preferably, the fixed plate is in the shape of a groove, and the conveyor belt passes through the groove cavity of the groove; at least four fixed sub-plates are also fixed on the fixed plate, and the four fixed sub-plates are used to fix the two ends of the two pressing plates.

[0010] Preferably, a fixing groove penetrating through the fixing sub-plate is provided in the middle thereof, for adjusting the angle between the pressing plate and the fixing plate.

[0011] Preferably, a handle collecting and transporting assembly is further provided on the supporting device, and the handle collecting and transporting assembly is fixed directly below the pressing plate and is used for collecting and transporting fallen handles.

[0012] Preferably, a collecting guide is also fixed on the supporting device, and the collecting guide is fixed to the end of the handle collecting and transporting assembly.

[0013] Preferably, a guide plate is also fixed on the supporting device, and the guide plate is located directly below the pressing plate and is inclined, so as to guide the fallen handle.

[0014] Preferably, the thickness of the portion of the handle hanging plate close to the conveyor belt and the curved portion is greater than the thickness of the portion of the handle hanging plate away from the conveyor belt.

[0015] Compared with the prior art, the present invention has the following beneficial effects: the handle on the bottle body is hung on the handle hanging plate, and the driving component drives the conveying component to move the packaging bottle. When the bottle body moves to contact the pressure plate, the bottle body is blocked by the pressure plate and cannot continue to move, while the handle is hung on the handle hanging plate and continues to move forward with the transmission of the conveying component, so that the force directions of the bottle body and the handle are opposite, and the pulling force on the bottle body and the handle increases with the increase of the moving distance of the handle. When the pulling force reaches the separation force between the bottle body and the handle, the handle and the bottle body are separated, and the bottle body pops outward and falls due to inertia, and the handle detaches from the opening of the handle hanging plate under the action of inertia and reaction force, and the handle and the bottle body are separated, without manual separation, thereby reducing labor costs and solving the technical problem of high labor costs for manual separation of defective products.

[0022] The present invention provides an embodiment of a bottle handle separation device. For details, please refer to Figures 1 to 3 .

[0023] A bottle handle separation device is used to separate the bottle body and handle of the bottle, the device comprises a device housing 1, a supporting device arranged in the device housing 1, and a separation device 2 fixed on the supporting device; the separation device 2 comprises a driving component, a conveying component and a limiting component; the driving component is used to drive the conveying component to operate; the conveying component is used to continuously convey the bottle to the limiting component to realize the separation of the bottle body and the handle, a handle hanging plate 6 is fixed on the conveying component, the bottle is hung on the conveying component through the handle hanging plate 6, the handle hanging plate 6 is curved, and the curved opening of the handle hanging plate 6 faces the conveying direction of the conveyor belt 9; the limiting component comprises a fixing plate 15 and a pressing plate 8 fixed on the fixing plate 15, when the bottle moves to contact the pressing plate 8, the pressing plate 8 blocks the bottle body of the bottle, hinders the bottle body from continuing to move, and promotes the separation of the bottle body and the handle.

[0024] It should be noted that the supporting device includes a supporting frame with four supporting legs 13, and at least one stabilizing plate 12 is fixed between each of the four supporting legs 13 for maintaining stability between the four supporting legs 13. The space between the supporting legs 13 is blocked by a limiting plate 3, and the driving component is a first motor fixed on one of the limiting plates 3 for driving the conveying component to operate.

[0025] The separation device 2 includes a handle hanging plate 6 and a bottle body pushing member; the handle hanging plate 6 is fixed on the conveyor belt 9 and moves with the conveying component. The handle hanging plate 6 is a curved plate-like structure. In this embodiment, the handle hanging plate 6 is plate-shaped and its bending angle is 90 degrees. The opening of the handle hanging plate 6 faces the direction of movement of the conveying component, which is used to place the handle and ensure that the handle can fall off the handle hanging plate 6 after being separated from the bottle body.

[0026] Specifically, there are at least two pressing plates 8, the two pressing plates 8 are parallel to each other and form an angle with the fixing plate 15, the spacing distance between the two pressing plates 8 is greater than the length of the handle, when the handle and the bottle body are transported to the pressing plate 8, the intersection of the pressing plate 8 and the fixing plate 15 first contacts the bottle body, and at this time the bottle body is stuck on the sides of the two pressing plates 8 away from the fixing plate 15, the pressing plate 8 limits the bottle body, preventing the bottle body from moving with the handle, forcing the handle and the bottle body to generate pulling forces in opposite directions.

[0027] Specifically, the conveying assembly includes two gears 5 and a conveyor belt 9 , and the handle hanging plate 6 is fixed on the conveyor belt 9 for conveying the packaging bottle to the pressing plate 8 .

[0028] Specifically, the fixing plate 15 is in a groove shape, and the conveyor belt 9 passes through the groove cavity of the groove; at least four fixing sub-plates 14 are also fixed on the fixing plate 15, and the four fixing sub-plates 14 are used to fix the two ends of the two pressing plates 8.

[0029] Specifically, a fixing groove is formed in the middle of the fixing sub-plate 14 and penetrates the fixing sub-plate 14 , so as to adjust the angle between the pressing plate 8 and the fixing plate 15 .

[0030] In this embodiment, one end of the four fixed sub-plates 14 is fixed to the two side surfaces of the fixed plate 15 respectively, the first ends of the four pressing plates 8 are fixed to the two side surfaces of the fixed plate 15, and the second ends are fixed to the other ends of the two fixed sub-plates 14, see Figure 3 In this embodiment, there are two pressing plates 8, and two limiting support structures 7 are fixed on the support frame. The limiting support structure 7 is in an inverted "U" shape. The bottom of the limiting support structure 7 is fixedly connected to the support device, and the two sides of the opening are respectively fixedly connected to two fixing plates 15. The two fixing plates 15 are respectively located on both sides of the transmission component, and the conveyor belt 9 on the transmission component passes through the groove cavity of the fixing plate 15; a fixing groove penetrating the fixing sub-plate 14 is opened in the middle of the fixing sub-plate 14, and the second end of the pressing plate 8 is fixed to the fixing sub-plate 14 by a bolt passing through the fixing groove, so as to adjust the angle between the pressing plate 8 and the fixing plate 15.

[0031] Specifically, a handle collecting and transporting assembly is also provided on the supporting device. The handle collecting and transporting assembly is fixed directly below the pressing plate 8 and is used for collecting and transporting fallen handles.

[0032] In this embodiment, the handle collecting and conveying assembly is a conveyor belt 9 device, which includes a conveyor belt and a second motor. The conveyor belt is located directly below the pushing member. There are two handle collecting and conveying assemblies, which are symmetrical about the connecting axis of the two gears 5 and are used to receive packaging bottles that may have fallen before the handles are separated.

[0033] Specifically, a collecting guide is also fixed on the supporting device, and the collecting guide is fixed to the end of the handle collecting and transporting assembly. The collecting guide in this embodiment is two guiding collecting plates 4 arranged obliquely to each other, which are fixed on the limiting plate 3 close to the supporting frame.

[0034] Specifically, a guide plate 10 is fixed to the supporting device. The guide plate 10 is located directly below the pressing plate 8 and is inclined, so as to guide the fallen handle.

[0035] Specifically, the thickness of the handle hanging plate near the conveyor belt 9 and the bent portion is greater than the thickness of the handle hanging plate 6 away from the conveyor belt 9. That is, when the bottle body and the handle are removed, the portion where the handle exerts a pulling force on the handle hanging plate 6 is thickened, thereby improving the strength of the handle hanging plate 6 and preventing deformation.

[0036] In this embodiment, the handle on the bottle body is hung on the handle hanging plate 6, and the driving component drives the conveying component to move the packaging bottle. When the bottle body moves to contact the pressure plate 8, the bottle body is blocked by the pressure plate 8 and cannot continue to move, while the handle is hung on the handle hanging plate 6 and continues to move forward with the transmission of the conveying component. In this way, the force directions of the bottle body and the handle are opposite, and the pulling force on the bottle body and the handle increases with the increase of the moving distance of the handle. When the pulling force reaches the separation force between the bottle body and the handle, the handle and the bottle body are separated, and the bottle body pops outward and falls due to inertia. The handle detaches from the opening of the handle hanging plate 6 under the action of inertia and reaction force, and the handle and the bottle body are separated. There is no need for manual separation, which reduces labor costs and solves the technical problem of high labor costs for manual separation of defective products.

[0037] The above disclosures are only several preferred embodiments of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
