DETAILED DESCRIPTION

[0032] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0033] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0034] This embodiment relates to a conveyor belt system, such as Figures 1-6 As shown, it includes: a first conveyor belt assembly 100 and a second conveyor belt assembly 200.

[0035] The first conveyor belt assembly 100 includes: a first frame 110, a first driving wheel 120 and a first driven wheel 130 arranged on the first frame 110, and a first belt body 140 wound around the first driving wheel 120 and the first driven wheel 130. The first driving wheel 120 drives the first belt body 140 to rotate around the driving wheel and the first driven wheel 130, so as to drive the objects on the first conveying surface of the first belt body 140 to move, thereby achieving the effect of conveying. A first support member 150 for supporting the first conveying surface is arranged on the inner side of the first conveying surface of the first belt body 140. The first support member 150 can support the first conveying surface, so that when the first conveying surface transmits some heavy objects, the first belt body 140 can maintain a good and stable shape to achieve a good conveying effect. It is prevented that the first belt body 140 is deformed by the pressure of the object and stretched, resulting in transmission failure or even the first belt body 140 is broken, thereby improving the stability of the first conveying assembly.

[0036] On one side of the first support member 150 close to the first conveying surface is a support surface 151. On the support surface 151, a negative pressure adsorption groove 152 is arranged along the conveying direction of the first conveying surface. On the first belt body 140, negative pressure adsorption holes 141 corresponding to the negative pressure adsorption groove 152 are provided to generate negative pressure on the surface of the first conveying surface of the first belt body 140, so as to adsorb and fix an object to the first belt body 140 and achieve a good and stable conveying effect. The negative pressure adsorption groove 152 is arranged along the conveying direction of the first conveying surface. During the movement of the first belt body 140, the negative pressure adsorption holes 141 on the first belt body 140 always cooperate with the negative pressure adsorption groove 152 to generate a negative pressure adsorption effect on the negative pressure adsorption holes 141, and always adsorb the object on the first belt body 140 to ensure the stability of the conveying. When facing some light objects, the first conveying surface can also be set in the vertical direction to realize the transfer of the object. At the same time, the negative pressure adsorption effect of the first conveying surface can also play the role of adsorption and material taking, adsorbing some light articles onto the first conveying surface to realize material taking.

[0037] In this embodiment, the support surface 151 of the first support member 150 is set as an arc-shaped support surface 151 that bends from vertically upward to the horizontal direction, and the first belt body 140 is attached to the arc-shaped support surface 151, so that the first conveying surface is set as an arc corresponding to the arc-shaped support surface 151, which can make the object realize arc-shaped conveying along the first conveying surface and change the conveying direction of the article to meet the requirements of article conveying. Of course, in other embodiments, the support surface 151 can also be set into other arc-shaped bending shapes according to actual conveying needs to achieve a good conveying effect. As a preferred solution, multiple groups of negative pressure adsorption holes 141 are provided and evenly arranged along the conveying direction of the first belt body 140, so that there are multiple adsorption positions on the first belt body 140, and multiple objects can be adsorbed and conveyed simultaneously, improving the conveying efficiency. At the same time, according to the setting interval between the negative pressure adsorption holes 141, the articles can be conveyed at intervals and regularly to achieve a good conveying effect.

[0038] As a preferred solution, multiple groups of negative pressure adsorption grooves 152 are provided in the negative pressure adsorption tank. The multiple groups of negative pressure adsorption grooves 152 are evenly distributed on the support surface 151. A plurality of negative pressure adsorption holes 141 are provided corresponding to the negative pressure adsorption grooves 152, so as to simultaneously adsorb and fix the product through a plurality of negative pressure adsorption holes 141. The acting surface for adsorbing the product is wider, and the adsorption and fixing force is greater, making the process of the product moving on the first conveying surface more stable. In this embodiment, rolling guide wheels 155 are provided in the negative pressure adsorption grooves 152. The rolling guide wheels 155 can reduce the friction between the first belt body 140 and the support surface 151, so that the movement of the first belt body 140 above the support surface 151 is smoother and better for transporting items. At the same time, it can reduce the wear of the support surface 151 on the first belt body 140 and improve the service life of the first belt body 140. Especially when facing the support surface 151 with an arc shape. The first belt body 140 needs to closely adhere to the support surface 151, and the rolling guide wheels 155 can greatly reduce the friction between the first belt body 140 and the support surface 151, ensuring the smooth operation of the first belt body 140.

[0039] In this embodiment, a negative pressure cavity 153 and a negative pressure generating port 154 are provided in the first support member 150. The negative pressure generating port 154 is communicated with the negative pressure cavity 153 and is used to generate negative pressure in the negative pressure cavity 153. The negative pressure generating port 154 can be connected to a negative pressure machine or an external negative pressure pipeline to maintain a certain negative pressure in the negative pressure cavity 153. A plurality of negative pressure adsorption grooves 152 are all communicated with the negative pressure cavity 153, so that good negative pressure adsorption effects can be achieved for each negative pressure adsorption groove 152.

[0040] As a preferred solution, a guide member 160 is further provided above the first conveying surface. The guide member 160 corresponds to the shape of the support surface 151, which can prevent items from falling out from the outside and achieve a certain protection effect. At the same time, the guide member 160 can also block some products that exceed the set specifications and prevent them from being transported to the output end of the first conveying surface.

[0041] The second transmission belt assembly is arranged at the rear end of the first conveyor belt assembly 100, so that the second conveying surface on the second transmission belt assembly is connected to the first conveying surface, and the articles on the first conveying surface are received, so that the articles continue to be transmitted on the second conveying surface. The second conveyor belt can be arranged horizontally, and there is no need to continue to use negative pressure to absorb the articles, so as to reduce the production and operation costs of the conveyor belt system. The second conveying surface of the second conveyor belt assembly 200 is higher than the first conveying surface of the first conveyor belt assembly 100, so that the articles can smoothly transition from the first conveying surface to the second conveying surface for continued transmission, and at the same time ensure that during the article conveying process, the second conveying surface will not scratch the first belt body 140 when receiving the articles and continuing to transmit the articles forward, thereby affecting the service life of the first belt body 140, so as to play a role of self-protection, improve the use stability and transmission speed of the conveyor belt system, and achieve good transmission and transition effects. As a preferred solution, the second conveying surface is 3mm higher than the first conveying surface, so that the articles can be smoothly input from the first conveying surface to the second conveying surface, ensuring a comfortable transition during the article transmission process. Of course, in other embodiments, the second conveying surface may be set to be 1 mm, 2 mm, 4 mm, 5 mm, etc. higher than the first conveying surface to achieve a good connection effect.

[0042] In this embodiment, a connecting plate 300 is connected between the first conveyor belt assembly 100 and the second conveyor belt assembly 200 to fix the relative position between the first conveyor belt assembly 100 and the second conveyor belt assembly 200, so that the transmission belt system maintains a stable transmission effect. A connecting block 310 is provided on the connecting plate 300, and the connecting block 310 is located between the first transmission surface and the second transmission surface, one end of which is connected to the first transmission surface, and the other end is connected to the second transmission surface, so as to guide the articles on the first transmission surface to the second transmission surface, so that the articles are transferred from the first transmission assembly to the second transmission assembly, and the smoothness of the overall operation of the transmission system is improved.

[0043] The second conveyor belt assembly 200 includes: a second frame 210, a second driving wheel 220 and a second driven wheel 230 arranged on the second frame 210, and a second belt body 240 wound around the second driving wheel 220 and the second driven wheel 230. The second driving wheel 220 drives the second belt body 240 to rotate around the driving wheel and the second driven wheel 230, so as to drive the objects on the second conveying surface of the second belt body 240 to move, thereby achieving the effect of conveying. A second support member 250 for supporting the second conveying surface is arranged on the inner side of the second conveying surface of the second belt body 240, and the second support member 250 can support the second conveying surface, so that when the second conveying surface transmits some heavy objects, the second belt body 240 can maintain a good and stable shape to achieve a good conveying effect. It is prevented that the second belt body 240 is deformed by the pressure of the object and stretched, resulting in transmission failure or even the second belt body 240 is broken, thereby improving the stability of the second conveying assembly.

[0044] In this embodiment, a wear-resistant interlayer 260 is provided between the second support member 250 and the second belt body 240 and below the conveying surface. The wear-resistant interlayer 260 is made of a material with a smooth surface and not easily prone to burrs. When the second conveyor belt assembly 200 operates, the movement of the second belt body 240 will rub against the bottom wear-resistant interlayer 260. The smooth surface of the wear-resistant interlayer 260 has a small frictional force and is not easily worn by the second belt body 240. Moreover, the wear-resistant interlayer 260 is not easily prone to burrs under the friction of the second belt body 240, thus avoiding burrs from piercing into the second belt body 240 and causing damage to the second belt body 240, and improving the durability of the second belt body 240. As a preferred solution, the wear-resistant interlayer 260 is a wear-resistant self-lubricating polymer plastic pad to achieve good wear resistance and has a self-lubricating effect, which can extend the service life of the second belt body 240. Of course, in other embodiments, the wear-resistant interlayer 260 can also be set as a partition made of other wear-resistant materials, or a wear-resistant coating provided on the surface of the second support member 250, or the second support member 250 itself can be made of a wear-resistant material that is not easily prone to burrs to reduce the wear of the second belt body 240 and improve its service life.

[0045] As a preferred solution, first transmission teeth are uniformly arranged along the conveying direction on the inner side of the first belt body 140, and first tooth rings matching the first transmission teeth are arranged on the circumferences of the first driving wheel 120 and the first driven wheel 130; through the cooperation of the first transmission teeth and the first tooth rings, the running stability of the first belt body 140 can be improved, and it is more difficult for the first belt body 140 to slip between the first driving wheel 120 and the first driven wheel 130, so as to achieve a good transmission effect. Second transmission teeth are uniformly arranged along the conveying direction on the inner side of the second belt body 240, and second tooth rings matching the second transmission teeth are arranged on the circumferences of the second driving wheel 220 and the second driven wheel 230; through the cooperation of the second transmission teeth and the second tooth rings, the running stability of the second belt body 240 can be improved, and it is more difficult for the second belt body 240 to slip between the second driving wheel 220 and the second driven wheel 230, so as to achieve a good transmission effect. In this embodiment, both the first transmission teeth and the second transmission teeth are set as arc-shaped transmission teeth, and the first tooth rings and the second tooth rings are arranged corresponding to the arc-shaped transmission teeth to ensure a stable transmission effect. The arc-shaped structure of the arc-shaped transmission teeth makes the friction between the arc-shaped transmission teeth and the first tooth rings and the second tooth rings smaller during meshing, and it is not easily worn by the arc-shaped transmission teeth, resulting in the failure of the arc-shaped transmission teeth and affecting the running effect of the conveyor belt. At the same time, the arc-shaped transmission teeth make the contact between the first belt body 140 and the first support member 150, and between the second belt body 240 and the second support member 250 more smooth, avoiding the wear of the transmission teeth on the belt body caused by the friction between the belt body and the support member and resulting in the failure of the transmission teeth, thereby improving the service life of the first belt body 140 and the second belt body 240.

[0046] As a preferred solution, the first conveying assembly further includes: a first tensioning wheel 170 is disposed on the first frame 110 and between the first driving wheel 120 and the first driven wheel 130. The first tensioning wheel 170 is movably disposed on the first frame 110, and the tightness of the first belt 140 can be adjusted by adjusting the position of the first tensioning wheel 170, so that the first belt 140 always maintains a good conveying effect. The second conveying assembly further includes: a second tensioning wheel 270 is disposed on the second frame 210 and between the second driving wheel 220 and the second driven wheel 230. The second tensioning wheel 270 is movably disposed on the second frame 210, and the tightness of the second belt 240 can be adjusted by adjusting the position of the second tensioning wheel 270, so that the second belt 240 always maintains a good conveying effect.
