Description

Technical Field

[0001] The utility model relates to the field of plane belt conveyors, in particular to an adjustable plane belt conveyor. Background Art

[0002] Logistics equipment is one of the main operating tools of modern enterprises and the basis for the rational organization of batch production and mechanized assembly line operations. There are many types of belt conveyors, among which flat belt conveyors are more widely used. The existing flat belt conveyors have an upward lifting function, which mainly relies on the friction of the belt itself to achieve anti-slip of items. However, the belts are greatly worn, and their service life will be greatly reduced after long-term use. Therefore, in order to solve the deficiencies in the existing technology, it is necessary to design a simple and adjustable flat belt conveyor. Utility Model Content

[0003] The utility model provides an adjustable flat belt conveyor to solve the problems of the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: an adjustable flat belt conveyor comprises: an inclined frame, an outer conveyor belt, an inner conveyor belt and a limit assembly, the outer conveyor belt is arranged on the inclined frame and is symmetrically arranged, a gap is provided between the outer conveyor belts, the inner conveyor belt is arranged on the inclined frame and is located in the gap, the limit assembly is provided with several groups, the limit assembly comprises a base, a guide rod, a guide plate, a push rod, a spring and a limit head, the base is fixed on the inner conveyor belt, the guide rod is fixed on the base, the guide plate is slidably arranged on the guide rod, a fixed sleeve is provided on the base, the spring is arranged in the fixed sleeve, the lower end of the push rod is arranged in the fixed sleeve, the push rod is fixedly connected to the guide plate, the limit head is fixed to the top of the push rod, and a guide surface is provided on the left side of the limit head.

[0005] As a further improvement, anti-slip protrusions are provided at intervals on the outer conveyor belt.

[0006] As a further improvement, a plug is provided at the upper end of the guide rod, the plug is located at the upper end of the guide plate, and the guide rod is symmetrically arranged in two groups.

[0007] As a further improvement, the push rod is threadedly connected with blocks at the upper and lower sides, and the two groups of blocks are located at the upper and lower sides of the guide plate.

[0008] As a further improvement, the limit head is arranged on the top of the push rod through a threaded connection.

[0009] Compared with the prior art, the adjustable flat belt conveyor of the utility model has the following beneficial effects:

[0010] The objects are lifted upward by two sets of outer conveyor belts. During the lifting process, the objects push the limit head downward along the guide surface until the objects move to the right side of the limit head. The limit head rebounds under the action of the lower end spring. During the process of the objects climbing upward through the outer conveyor belt, the limit head climbs upward synchronously through the inner conveyor belt. At the same time, the limit head is located on the left side of the objects to prevent them from falling, which greatly reduces the wear of the conveyor belt and increases its service life.

DETAILED DESCRIPTION

[0015] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] Below is a combination of the embodiments and the attached Figures 1 to 3 , the technical solution of the utility model is further elaborated.

[0018] Example 1

[0019] An adjustable flat belt conveyor comprises: an inclined frame 1, an outer conveyor belt 2, an inner conveyor belt 3 and a limit assembly 4, wherein the outer conveyor belt 2 is arranged on the inclined frame 1 and is symmetrically arranged, a gap is provided between the outer conveyor belts 2, the inner conveyor belt 3 is arranged on the inclined frame 1 and is located in the gap, the limit assembly 4 is provided with several groups, the limit assembly 4 comprises a base 41, a guide rod 42, a guide plate 43, a push rod 44, a spring 45 and a limit head 47, the base 41 is fixed on the inner conveyor belt 3, the guide rod 42 is fixed on the base 41, the guide plate 43 is slidably arranged on the guide rod 42, a fixing sleeve 46 is provided on the base 41, the spring 45 is arranged in the fixing sleeve 46, the lower end of the push rod 44 is arranged in the fixing sleeve 46, the push rod 44 is fixedly connected to the guide plate 43, the limit head 47 is fixed to the top of the push rod 44, and a guide surface 471 is provided on the left side of the limit head 47.

[0020] like Figure 1 to Figure 3 As shown, the working principle of the utility model is as follows: the articles are lifted upward by two sets of outer conveyor belts 2, and during the lifting process, the articles push the limit head 47 downward along the guide surface 471 until the articles move to the right side of the limit head 47, and the limit head 47 rebounds under the action of the lower end spring 45, and during the process of the articles climbing upward through the outer conveyor belt 2, the limit head 47 synchronously climbs upward through the inner conveyor belt 3, and at the same time, the limit head 47 is located on the left side of the articles to prevent the articles from falling, thereby greatly reducing the wear of the conveyor belt and increasing the service life.

[0021] As a further preferred embodiment, anti-skid protrusions 21 are provided at intervals on the outer conveyor belt 2, and the anti-skid protrusions 21 increase the friction force during the lifting process of the objects.
