Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to a hose sidewall conveyor belt. Background Art

[0002] With the continuous improvement of the automation level of the food industry, conveyor belts are used in all processes of material transportation. Due to the small size of food, the material is easily deviated from the route during transportation, so that it falls off the conveyor belt, causing the material to be damaged or even fall into the equipment, affecting its normal operation. To solve this problem, skirt-shaped sidewall belts are currently available on the market, that is, skirt-like wavy sidewalls are added on both sides of the conveyor belt to prevent the material from falling during transportation.

[0003] During the use of the skirt sidewall belt, since the sidewall is bonded to both sides of the conveyor belt in a corrugated form, on the one hand, the material is easily retained in the depression of the sidewall during transportation, affecting the transportation efficiency of the material; on the other hand, material debris is easily retained at the corners of the sidewall, making the conveyor belt difficult to clean and easily causing pollution to the subsequent transportation of materials. Utility Model Content

[0004] In view of this, the utility model provides a hose rib conveyor belt. The utility model sets hose ribs on both sides of the conveyor belt, which can prevent materials from being stranded during transportation, prevent material debris from remaining, improve transportation efficiency, and avoid pollution to subsequent material transportation.

[0006] A hose rib conveyor belt comprises a base belt and hose ribs arranged on both sides of the base belt; the hose ribs are arched structures and are made of PU or PVC.

[0007] Preferably, the hose rib is made of a film, and the thickness of the film is 1 to 3 mm.

[0008] Preferably, the height of the hose rib is 10-30 mm, and the width is 10-25 mm.

[0009] Preferably, the length direction of the hose rib is parallel to the length direction of the base belt.

[0016] In the utility model, the length direction of the hose rib is parallel to the length direction of the base belt and runs through the entire base belt, and the two long sides of the hose rib are bonded to the surface of the base belt.

[0017] In the utility model, the hose retaining edge is made of a film, and the thickness of the film is preferably 1 to 3 mm. The utility model controls the thickness of the film to 1 to 3 mm, which can ensure a certain support effect, ensure that an arched structure can be formed by vacuum suction, and ensure the tensile strength after the two ends of the film are compounded with the base belt.

[0018] In the present invention, the height of the hose rib (i.e. the distance between the highest point of the arch and the base band) is preferably 10-30 mm, more preferably 15-25 mm, and the width (i.e. the distance between the two long sides) is preferably 10-25 mm, more preferably 15-20 mm.

[0019] In the present invention, the method for preparing the hose sidewall conveyor belt described in the above scheme preferably comprises the following steps:

[0020] The hose ribs are prepared on both sides of the base belt to obtain the hose rib conveyor belt; the preparation method of the single-side hose rib includes:

[0021] Preheating the film with infrared rays; the film is a PU film or a PVC film;

[0022] The preheated film enters the groove of the groove roller, and the film is formed by vacuuming to obtain an arched film; the surface of the groove roller is provided with a circle of grooves, and the cross-sectional shape of the grooves is an arch;

[0023] The two ends of the arched PU film are laminated with the base tape by hot air heating.

[0024] The utility model first preheats the film with infrared rays. In the utility model, the film is a PU film or a PVC film, and the thickness of the film is 1 to 3 mm; the temperature of the infrared preheating is preferably 60 to 115°C, and specifically, when the film is a PU film, the temperature of the infrared preheating is preferably 60 to 100°C, and more preferably 80°C; when the film is a PVC film, the temperature of the infrared preheating is preferably 75 to 115°C, and more preferably 95°C; the utility model heats the film to soften by infrared preheating, so as to facilitate the subsequent formation of an arch by vacuuming.

[0025] The preheated film enters the groove of the groove roller, and the film is formed by vacuuming to obtain an arched film. In the utility model, the surface of the groove roller is provided with a circle of grooves, and the cross-sectional shape of the groove is arched; the depth of the groove is preferably 10 to 30 mm, more preferably 15 to 25 mm, and the width is preferably 10 to 25 mm, more preferably 15 to 20 mm; the groove roller can be vacuumed. In a specific embodiment of the utility model, the interior of the groove roller is a hollow structure, and a rotary joint is provided on the shaft head of the roller, and the rotary joint is used to connect a vacuum pump. The bottom surface of the groove of the roller is provided with a plurality of vacuuming holes, and the distance between adjacent vacuuming holes is preferably 10 mm. A slidable sealing patch is preferably provided in the hollow interlayer of the groove roller and close to the bottom of the groove, and the sealing patch can be used for P The vacuum hole at the contact point between the U film and the groove is sealed. Before the softened film enters the groove, the sealing sheet slides on the bottom of the groove to seal the hole. When the film enters the groove, the sealing sheet slides away. At this time, the PU film plays a sealing role and is formed under vacuum conditions. When the film leaves the roller after being formed, another set of sealing sheets seals the vacuum hole at the rib position. The subsequent softened film enters the groove again and repeats the above process to achieve continuous operation. In the utility model, since the softened film has a large fluidity, the utility model is provided with a sealing patch to prevent the softened film from flowing into the vacuum hole. The softened film solidifies after entering the groove. At this time, the sealing patch slides away and the film is formed under the action of vacuum.
