Description

Technical Field

[0001] This utility model belongs to the field of transportation and transfer technology, specifically a high-load mold transfer device. Background Technology

[0002] To ensure that certain agricultural products have a uniform appearance when sold, they are often shaped by pressing. During the pressing process, a certain amount of time is needed to maintain the shape. Therefore, they are stored and transported by stacking them one by one, which solves the problems of production cycle and shaping time. After the shaping time is up, the mold needs to be removed for demolding. The molds are usually stacked from bottom to top. This not only ensures the normal operation of the entire production line, but also keeps the mold with the longest shaping time on top. Therefore, it can be directly removed without any other operations.

[0003] The problem in reality is that, due to the long shaping time of these fruits, the molds are stacked very high from bottom to top. When it is necessary to remove the molds from the high position, the traditional robotic arm cannot achieve the appropriate stroke. Moreover, the molds themselves are very heavy. If a long stroke robotic arm is used to transfer the molds, it will not only affect the service life of the robotic arm but also affect the accuracy of the mold placement during the transfer process, which in turn will affect the production progress of the entire production line. Therefore, a mold transfer device that can adapt to high-load work is proposed. Utility Model Content

[0004] To address the above problems, this utility model provides a high-load mold transfer device to solve the problem that existing robotic arms cannot transport and transfer heavy molds with long strokes, high loads, and accurate positioning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-load mold transfer device includes a symmetrically arranged and synchronously moving transmission chain assembly. The transmission chain assembly is arranged vertically in the conveying direction. A support plate is fixedly installed on the transmission chain of the transmission chain assembly. When the support plate moves to the middle, it forms a support platform for supporting the mold.

[0007] The conveyor chain assembly has a first guard plate on its side, and a second guard plate is fixedly mounted on the first guard plate. The area enclosed by the first guard plate and the second guard plate forms a protective cavity for the conveyor chain assembly. The second guard plate has outwardly extending bends. A first roller is connected to the support plate. The first roller and the bends on the second guard plate roll against each other to prevent the support plate from tilting when placing the mold.

[0008] As a further improvement to the above solution, a connecting plate is also fixedly installed on the transmission chain assembly, and a second roller is connected to the connecting plate. The second roller rolls against the bends on the second guard plate, so that the transmission chain assembly can move vertically within the protective cavity formed by the first guard plate and the second guard plate.

[0009] As a further improvement to the above solution, the support plate includes a vertically arranged connecting part and a horizontally arranged support part, the connecting part being used to fix itself to the conveyor chain on the conveyor chain assembly.

[0010] The top surface of the support is provided with steps to limit the side position of the mold and prevent the mold from slipping.

[0011] As a further improvement to the above solution, a support is fixedly installed on the side of the support plate, and the first roller is rotatably arranged on the support. The first rollers are arranged in pairs on the support to prevent the mold from tilting after it is placed on the support plate.

[0012] As a further improvement to the above scheme, there is a gap between the first roller and the support plate, which allows the second guard plate to pass through it to make contact with and guide the first roller.

[0013] As a further improvement to the above solution, a support frame is provided on the outside of the transmission chain assembly, the conveyor sprockets of the transmission chain assembly are rotatably mounted on the support frame, and a drive mechanism is fixedly provided at the bottom of the support frame. The drive mechanism drives the symmetrically arranged conveyor sprockets of the transmission chain assembly to rotate synchronously through the chain.

[0014] As a further improvement to the above solution, a tensioning mechanism for controlling the tension of the chain is fixedly installed on the side of the support frame.

[0015] The tensioning mechanism includes a fixed seat that is fixedly disposed between the fixed seat and the support frame, an adjustable slide seat that is mounted on the fixed seat, and a sliding column that slides up and down and guides the fixed seat.

[0016] A tension sprocket is rotatably mounted on the slide and is connected to the chain for transmission. When the tension sprocket is adjusted up and down, it pulls the chain to tension.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model adopts a symmetrically arranged transport chain assembly. With the support of the support plate on the mold, the mold is transported and transferred synchronously downwards. This method can adapt to the transportation requirements of long strokes. Especially for very heavy molds, the transport chain assembly has a strong load-bearing capacity, can adapt to high-load operation requirements, and has a longer service life. Moreover, a first guard plate and a second guard plate are set on the side of the conveyor chain of the transport chain assembly for protection, which can prevent jamming or swinging during operation. With the interaction of the second guard plate and the first roller, the mold can be prevented from tilting to the middle due to gravity after being placed on the support plate, and the mold can be kept moving vertically downwards smoothly.

[0019] 2. By setting the second roller, the conveyor chain of the transmission chain assembly can be kept in a vertical state when the second roller rolls on the second guard plate, reducing the swaying and tilting phenomena during its movement, making the transportation more stable, and ensuring the accurate positioning of the final mold when it is transported to the corresponding position.

[0020] 3. By using a drive mechanism to synchronously drive the symmetrical transmission chain components through chain transmission, the use of electrical components such as controllers can be reduced. This allows for synchronous movement through mechanical transmission, avoiding safety hazards caused by asynchronous movement of the transmission chain components on both sides in the event of power failure or other malfunctions.

[0033] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0034] like Figure 1-11 As shown, the specific solution of this embodiment is: a high-load mold transfer device, including symmetrically arranged and synchronously moving transmission chain assemblies 1. Specifically, in this embodiment, four sets of transmission chain assemblies 1 are arranged, with two transmission chain assemblies 1 on each side forming a set, and the conveying sprockets are all coaxially driven, symmetrical on both sides, and the conveying direction of the transmission chain assemblies 1 is vertically arranged vertically, as shown. Figure 1 As shown, a support frame 8 is provided on the outer side of the transmission chain assembly 1. The conveyor sprocket of the transmission chain assembly 1 is rotatably mounted on the support frame 8, and a drive mechanism is fixedly mounted at the bottom of the support frame 8. The drive mechanism includes a drive motor connected to a reducer. The reducer has two output ends. The two output ends of the drive mechanism drive the symmetrically arranged conveyor sprockets of the transmission chain assembly 1 to rotate synchronously through a chain. In this embodiment, mechanical transmission is used to achieve synchronous transmission, which can reduce the use of electrical components. In particular, it can avoid the phenomenon that the two sides of the transmission chain assembly 1 are not synchronized in the event of a power outage or electrical fault, thereby avoiding safety hazards.

[0035] A support plate 2 is fixedly installed on the conveyor chain of the transmission chain assembly 1, as shown in the attached figure. Figure 4As shown, the support plate 2 includes a vertically arranged connecting part 21 and a horizontally arranged support part 22. The connecting part 21 is used to fix itself to the conveyor chain on the conveyor chain assembly 1. The top surface of the support part 22 is provided with a step to limit the side position of the mold and prevent the mold from slipping. When the support plate 2 moves to the middle, it forms a support platform for supporting the mold. See attached figure. Figure 1 , 2 As shown in Figures 5 and 9, when the two symmetrical support plates 2 move to the middle position, the two support plates 2 are at the same height. After the mold is placed on the two support plates 2, it can realize the function of a support platform for transmitting the mold downward.

[0036] The conveyor chain assembly 1 has a first guard plate 3 on its side, as shown in the attached diagram. Figure 11 The first guard plate 3 is fixedly mounted on the support frame 8, and the second guard plate 4 is fixedly mounted on the first guard plate 3. The area enclosed by the first guard plate 3 and the second guard plate 4 forms a protective cavity for the conveyor chain assembly 1. This protective cavity is mainly used to temporarily separate the conveyor chain on the conveyor chain assembly 1 to prevent jamming or swaying during the downward movement of the transport mold. The second guard plate 4 has outwardly extending bends and is in an "L" shape. The support plate 2 is connected to a first roller 5. The first roller 5 rolls against the bends on the second guard plate 4 to prevent the support plate 2 from tilting when placing the mold. Specifically, refer to the attached document. Figure 4 As shown, a support plate 2 is fixedly provided with a support 10 on its side. The first roller 5 is rotatably arranged on the support 10, and the first roller 5 is arranged in pairs on the support 10 to prevent the mold from tilting after it is placed on the support plate 2. There is a gap between the first roller 5 and the support plate 2. This gap allows the second guard plate 4 to pass through it to make contact and guide with the first roller 5. Therefore, the second guard plate 4 plays a supporting and guiding role for the first roller 5, so that the support plate 2 can descend vertically when conveying the mold downwards, avoiding the phenomenon of unstable mold placement caused by tilting.

[0037] like Figure 1 As shown, in a preferred embodiment, the transmission chain assembly 1 is further fixedly provided with a connecting plate 6. Multiple connecting plates 6 are provided and arranged between the two support plates 2. A second roller 7 is connected to the connecting plate 6. The second roller 7 rolls against the bend on the second guard plate 4, so that the transmission chain assembly 1 can move vertically within the protective cavity formed by the first guard plate 3 and the second guard plate 4. In this embodiment, by providing multiple connecting plates 6 and second rollers 7, the transmission chain assembly 1 can be confined within the protective cavity of the first guard plate 3 and the second guard plate 4, reducing the swinging and tilting of the transmission chain assembly 1 during the movement process, making the transportation more stable, and ensuring the accurate positioning of the final mold when transported to the corresponding position.

[0038] like Figure 2 , 10 As shown, in a preferred embodiment, a tensioning mechanism for controlling chain tension is fixedly provided on the side of the support frame 8; the tensioning mechanism includes a fixed seat 9 fixedly provided with the support frame 8, a slide seat 91 adjustablely provided on the fixed seat 9, and a slide column 93 fixedly provided on the slide seat 91 for sliding and guiding each other up and down with the fixed seat 9; a tensioning sprocket 92 rotatably provided on the slide seat 91 and connected to the chain for transmission, and the tensioning sprocket 92 pulls the chain to tension when it is adjusted up and down.

[0039] The specific working principle of this utility model is as follows: When in use, the conveyor sprocket of the transmission chain assembly 1 is driven to rotate synchronously by the drive mechanism, so that the symmetrically arranged transmission chain assemblies 1 on both sides move synchronously in the vertical direction; when the support plates 2 on both sides move to the middle position with the conveyor chain, the support plates 2 on both sides form a horizontal support platform at the same height. At this time, the mold to be transferred can be placed on the step surface of the support part 22. The step structure can effectively limit the side position of the mold and prevent the mold from slipping.

[0040] After the mold is placed, the drive mechanism continues to drive the transmission chain assembly 1 to move downward. During this process, the first roller 5 on the support plate 2 rolls in close contact with the bent part of the second guard plate 4. Under the guidance of the second guard plate 4, the support plate 2 is kept horizontal at all times to avoid tilting due to the weight of the mold. At the same time, the second roller 7 on the connecting plate 6 rolls along the second guard plate 4 to further limit the swing of the conveyor chain of the transmission chain assembly 1 in the protective cavity and ensure the overall transportation stability, thereby transferring the mold downward during the downward movement of the support plate 2.

[0041] If the chain becomes slack during transportation, the tensioning sprocket 92 can be moved up and down by adjusting the slide 91 of the tensioning mechanism, thereby pulling the chain to tension and ensuring the synchronous transmission accuracy of the transmission chain assembly 1. When the mold is transported to the lowest target position, the high-load, long-stroke stable transfer of the mold is completed, and the mold is continuously transferred downward according to the actual situation.
