Description

Technical Field

[0001] The invention relates to the technical field of conveying chain plates, and in particular to a side-driven turning chain plate. Background Art

[0002] Conveyor chain usually refers to a device used to transport or lift materials. It consists of a spiral chain or belt power transmission system and a series of plates connected to the chain. It is usually used in the process of material conveying, lifting or handling in industrial production.

[0003] The working principle of conveyor chain is to drive the plates connected to the chain through the rotation of the chain or belt to convey or lift the materials along a specific path of the equipment. Conveyor chain is widely used in many industrial fields, such as metallurgy, chemical industry, building materials, food processing, etc. They can be customized according to specific process requirements and working environment to meet the material conveying needs in different scenarios.

[0004] Conventional conveyor chain plates are mostly driven by chain transmission to move them, so as to complete the conveying of items placed on the surface. For example, a spiral machine chain plate with the authorization announcement number CN206511504U, by fixing two relative guide bearings on the outside of the support seat, contacts the support rail, and changes the previous sliding friction into rolling friction, which greatly reduces the running resistance, runs more smoothly, and avoids the situation of chain breakage. In actual use, it is found that since the chain is set at the bottom of the support seat, if the conveying equipment needs to turn, the chain needs to be set and adjusted, and the turning radius of the chain is large. In the food packaging workshop, since food processing requires quantitative weighing, putting it into the packaging container, and sealing the packaging container, in order to improve the utilization rate of the workshop space and limited by the space layout, adjacent workstations often need to use the conveyor chain plate conveying equipment for turning guidance. The conveyor chain plate with the chain as the conductive structure has a large turning radius, and the chain is set below the support seat, resulting in a large overall thickness. Under the condition of constant conveying height, the ground clearance of the bottom of the equipment is small. The equipment needs to be raised during subsequent maintenance, resulting in great inconvenience in maintenance.

[0005] For this purpose, we propose a side-driven turning chain plate. Summary of the invention

[0006] The main purpose of the present invention is to provide a side-driven turning chain plate, which adopts a side-driven method through a keel sprocket and a spiral transmission, which is different from a chain transmission structure, so that the overall thickness of the equipment is smaller, which is convenient for subsequent maintenance, and the transmission is more stable and efficient, with a smaller turning radius and smoother movement.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] A side-driven turning chain plate comprises an upper cover, a spiral, a track and a keel sprocket. The spiral is arranged below the upper cover, and a groove is constructed on the surface of the spiral for limiting the position of the upper cover. The spirals are connected end to end in sequence. The track is symmetrically arranged below the upper cover, and the inner wall of the track is rollingly connected to both sides of the spiral to limit and guide the spiral. The keel sprocket is meshed and connected between adjacent spiral side walls, and the spiral can be driven to move by rotating the keel sprocket.

[0009] Preferably, the upper cover includes a cover plate, a semicircular notch, a semicircular protrusion and an arc-shaped limit block. The cover plate is distributed in a horizontal array, a semicircular notch is constructed on one side of the cover plate, and a semicircular protrusion adapted to the semicircular notch is integrally formed on the other side of the cover plate, and the arc-shaped limit block is arranged on the bottom surface of the semicircular protrusion.

[0010] Preferably, the spiral includes a head ring, a pin hole, a side panel, a connecting pin, a fitting sheet and an engaging opening, the head ring is arranged below the upper cover, the side panels are symmetrically arranged and integrally formed on the outer periphery of the head ring, the fitting sheet is integrally formed on the surface of the side panel, and the fitting sheet extends toward the side away from the side panel, the outer wall of the fitting sheet is constructed with an engaging opening adapted to the keel sprocket, the outer periphery of the head ring and the side of the side panel away from the head ring are constructed with pin holes, and connecting pins that pass through the head ring are passed through the pin holes of the side panel.

[0011] Preferably, the spiral further comprises hook feet and a vertical bearing, the hook feet are symmetrically arranged and integrally formed on the separated sides of the side plates, and the vertical bearing is rotatably installed between the hook feet and the side walls of the side plates.

[0012] Preferably, the spiral further comprises a horizontal bearing, the side wall of the side plate is constructed with a rectangular groove located below the bonding sheet, and the horizontal bearing is rotatably installed in the rectangular groove.

[0013] Preferably, the upper cover further comprises a side baffle, which is integrally formed on the edge side of the cover plate surface and is arranged on the side of the cover plate surface away from the keel sprocket.

[0014] Preferably, one side surface and the other side bottom surface of the cover plate are both configured with docking grooves, and the docking grooves are connected to the semicircular notch and the semicircular protrusion.

[0015] Preferably, the surface of the bonding sheet is configured with an arc-shaped limiting groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention can drive the upper cover to move by limiting the spiral from the side through the spiral and keel sprockets. Different from the traditional chain drive method, the overall thickness of the equipment is small, and the bottom gap of the equipment is larger when the conveying surface height is constant after the equipment is assembled. The operating space is larger during subsequent maintenance, and the possibility of lifting the equipment is lower. In addition, the precise matching of the meshing mouth of the keel sprocket and the spiral side wall makes the transmission more stable and efficient, which can meet the food processing requirements of glass-filled food industries such as beverages, canned food and brewing. The transmission structure of the keel sprocket and the spiral makes the upper cover have a smaller turning radius, so as to facilitate the transfer of workstations in the food production workshop.

[0018] 2. The hooks, vertical bearings and horizontal bearings provided in the present invention ensure that when the spiral moves between the tracks, the vertical bearings and horizontal bearings respectively roll in contact with the horizontal and vertical surfaces inside the tracks, which not only limits the position of the spiral but also makes the spiral move more smoothly between the tracks, thereby ensuring quality and reliability.

[0019] 3. The upper cover of the present invention has a side barrier strip on the surface of the upper cover, which can block and limit the objects when the objects move and turn with the upper cover, thereby preventing the objects from falling from the edge of the cover surface under the action of centrifugal force.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figure 1-8 As shown, a side-driven turning chain plate includes an upper cover 1, a spiral 2, a track 3 and a keel sprocket 4. The spiral 2 is arranged below the upper cover 1, and a groove is constructed on the surface of the spiral 2 for limiting the placement of the upper cover 1. The spirals 2 are connected end to end in sequence. The track 3 is symmetrically arranged below the upper cover 1, and the inner wall of the track 3 is rollingly connected to both sides of the spiral 2, which plays a limiting and guiding role for the spiral 2. The keel sprocket 4 is meshed and connected between adjacent side walls of the spiral 2, and the spiral 2 can be driven to move by rotating the keel sprocket 4.

[0031] An upper cover 1 is provided above the spiral 2 in a one-to-one corresponding manner. The upper cover 1 is limitedly overlapped on the surface of the spiral 2 and moves smoothly with the spiral 2. The keel sprocket 4 is concentrically driven by a limit driving device. When the keel sprocket 4 rotates, it can drive the spiral 2 to move smoothly to one side.

[0032] In this embodiment, refer to Figure 5-8 The upper cover 1 includes a cover plate 11, a semicircular notch 12, a semicircular protrusion 13 and an arc-shaped limit block 16. The cover plate 11 is distributed in a horizontal array. A semicircular notch 12 is constructed on one side of the cover plate 11, and a semicircular protrusion 13 adapted to the semicircular notch 12 is integrally formed on the other side of the cover plate 11. The arc-shaped limit block 16 is arranged on the bottom surface of the semicircular protrusion 13.

[0033] The semicircular notch 12 and the semicircular protrusion 13 facilitate the placement of the cover plate 11 on the surface of the spiral 2. In addition, under the action of the semicircular notch 12 and the semicircular protrusion 13, the gap between adjacent cover plates 11 is transformed from a straight line to a curve, which effectively prevents the linear protrusion from getting stuck when transporting packaging cans with linear protrusions on the bottom.

[0034] In this embodiment, refer to Figure 5-7The spiral 2 includes a head ring 21, a pin hole 22, a side plate 23, a connecting pin 24, a fitting piece 27 and an engagement opening 28. The head ring 21 is arranged below the upper cover 1, and the side plates 23 are symmetrically arranged and integrally formed on the outer periphery of the head ring 21. The fitting piece 27 is integrally formed on the surface of the side plate 23, and the fitting piece 27 extends toward the side away from the side plate 23. The outer wall of the fitting piece 27 is constructed with an engagement opening 28 adapted to the keel sprocket 4. Pin holes 22 are constructed on the outer periphery of the head ring 21 and on the side of the side plate 23 away from the head ring 21, and a connecting pin 24 that passes through the head ring 21 is inserted between the pin holes 22 of the side plate 23, and an arc-shaped limit groove is constructed on the surface of the fitting piece 27.

[0035] The meshing opening 28 meshes with the keel sprocket 4, making the transmission more stable and efficient, so that when the object is transferred to the next station, the relative position on the upper cover 1 is not easily changed, and the adjacent spirals 2 are conveniently connected by the connecting pin 24.

[0036] In this embodiment, refer to Figure 5-7 The spiral 2 also includes a hook foot 25 and a vertical bearing 26. The hook foot 25 is symmetrically arranged and integrally formed on the separated side of the side plate 23. The vertical bearing 26 is rotatably installed between the hook foot 25 and the side wall of the side plate 23. The spiral 2 also includes a horizontal bearing 29. The side wall of the side plate 23 is constructed with a rectangular groove located below the bonding sheet 27, and the horizontal bearing 29 is rotatably installed in the rectangular groove.

[0037] The horizontal bearing 29 contacts the inner vertical surface of the track 3, and can provide horizontal limit for the spiral 2 located between the track 3 to prevent excessive contact between the outer diameter side of the spiral 2 and the track 3 when turning, which may cause severe wear of the track 3. At the same time, it can also provide certain support for the spiral 2 to ensure the stability of the spiral 2 when moving. The vertical bearing 26 is supported on the inner horizontal surface of the track 3, which is beneficial to reduce the friction between the spiral 2 and the track 3 when moving, thereby extending the service life of the equipment.

[0038] In this embodiment, refer to Figure 1 The upper cover 1 further includes a side baffle 15 , which is integrally formed on the edge of the cover plate 11 , and is arranged on the side of the cover plate 11 away from the keel sprocket 4 .

[0039] At the turning part, since the objects will move outward due to the influence of centrifugal force, and it is not convenient to set a slope on the upper cover 1 to reduce the centrifugal force, a side guard bar 15 is set on the outer side of the turn of the cover plate 11 to limit and intercept the objects, so as to prevent the objects from falling from the edge of the cover plate 11 under the action of centrifugal force.

[0040] In this embodiment, refer to Figure 5 A docking groove 14 is constructed on one side surface and the other side bottom surface of the cover plate 11 , and the docking groove 14 is connected to the semicircular notch 12 and the semicircular protrusion 13 .

[0041] Under the action of the docking groove 14, the influence of the gap between adjacent cover plates 11 on the conveying of articles can be further reduced, the width of the gap between adjacent cover plates 11 can be effectively reduced, and the protrusion at the bottom of the article can be prevented from being stuck in the gap.

[0042] It should be noted that the present invention is a side-driven turning chain plate. When assembling, the adjacent spirals 2 are connected head to tail, and the spirals 2 are located inside the closed track 3. The head ring 21 of the rear spiral 2 is placed between the side plates 23 of the front spiral 2, and a connecting pin 24 is inserted between the side plates 23. At the same time, the connecting pin 24 passes through the pin hole 22 of the inner head ring 21, thereby completing the connection of the adjacent spirals 2. The horizontal bearing 29 and the vertical bearing 26 of the spiral 2 are aligned with the vertical surface and the horizontal surface of the inner wall of the track 3 and then placed inside the track 3. The keel sprocket 4 installed on the output shaft of the driving device is engaged with the engagement opening 28 on one side of the spiral 2 fitting piece 27 (keel sprocket 4 is kept on the inner bend side of the turn), and then the cover plate 11 is placed on the surface of the spiral 2 fitting piece 27 according to the corresponding orientation. When the keel sprocket 4 is rotated by the driving device, the spiral 2 is driven to move between the tracks 3. Thanks to the dual support and limitation of the horizontal bearing 29 and the vertical bearing 26, the spiral 2 moves smoothly, and the food packaging container placed on the surface of the cover plate 11 moves to the next workstation with the cover plate 11.

[0043] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
