Description

Technical Field

[0001] The invention relates to a food packaging production line, in particular to a food packaging plastic sealing machine and a conveyor belt connecting device and a production line with the device. Background Art

[0002] After the meatballs, buns, dumplings and other granular foods are bagged, they will be opened and sealed by the food packaging laminator, and then transported to the next station for inspection and packing through the laminator conveyor belt. For food packaging bags without inner trays, after the food is bagged, the staff needs to pinch the mouth of the food packaging bag filled with food to prevent the meatballs and other foods from rolling out. At the same time, the laminator conveyor belt on the side of the food packaging laminator drags the mouth of the food packaging bag filled with food through the hot press port of the food packaging laminator for plastic sealing.

[0003] A roller conveyor is usually arranged between the food packaging laminator and the downstream conveyor belt to facilitate the food packaging bags containing food to slide to the downstream conveyor belt; wherein baffles are arranged on the left and right sides of the roller conveyor belt to prevent the food packaging bags from rolling down.

[0004] Since the food in the food packaging bags is in granular form and some of the food is small in size, it is very easy for the food at the corner of the food packaging bag to get stuck in the gap between the adjacent rollers of the roller conveyor belt. When production is busy, multiple bags of food will pass through the roller conveyor belt at the same time, and it is easy for multiple bags of food to get stuck between the two baffles. Summary of the invention

[0005] The object of the present invention is to provide a food packaging laminator and conveyor belt connecting device which can reduce the possibility of a food packaging bag containing granular food being stuck and facilitate the smooth flow of the plastic-sealed food packaging bag.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a food packaging laminator and conveyor belt connecting device, comprising baffles located on left and right sides and extending upward, a plurality of roller conveyor belts of equal height and spaced apart on the left and right sides are arranged between the two baffles, a supporting pad is arranged between two adjacent roller conveyor belts on the left and right sides, the upper end surface of the supporting pad is close to the upper edge of the roller of the roller conveyor belt or the upper end surface is flush with the upper edge of the roller of the roller conveyor belt, the upstream end of the roller conveyor belt is used to connect with the laminator conveyor belt at the food packaging laminator, the downstream end of the roller conveyor belt is used to connect with the conveyor belt, the flow direction of the roller conveyor belt is the same as its own extension direction, the flow direction of the roller conveyor belt forms an angle with the flow direction of the laminator conveyor belt and the conveyor belt at the food packaging laminator, the downstream end of the roller conveyor belt is closer to the center line of the conveyor belt than its own upstream end, and the distance between the upstream ends of two adjacent roller conveyor belts is greater than the distance between the downstream ends of two adjacent roller conveyor belts.

[0007] The device of the present invention reduces the contact area and contact time between the food packaging bag and the roller when rolling on the roller conveyor belt by arranging roller conveyor belts spaced apart on the left and right, so as to reduce the possibility that granular foods such as meatballs located at the corners of the food packaging bag will be stuck between the rollers; at the same time, the extension direction and the flow direction of the multiple roller conveyor belts spaced apart form an angle with the flow directions of the plastic sealing machine conveyor belt and the conveyor belt, so that the food packaging bags entering the device from different directions can be guided, and the flow path of the food packaging bags can be adjusted at the same time, so that the food packaging bags can flow to the conveyor belt more smoothly, and multiple packaging bags can be prevented from being stuck between the baffles on both sides.

[0008] Among them, by setting a support surface, and the support surface is flush with or close to the upper edge of the roller, the possibility of contact between the food packaging bag and the roller can be reduced while ensuring that the food packaging bag is easy to slide, and the food packaging bag is prevented from being stuck between two adjacent roller conveyor belts, further reducing the possibility of the food packaging bag getting stuck. The roller conveyor of the present invention can adopt a conventional existing roller conveyor belt, including two parallel fixed plates and a plurality of rollers rotatably set between the two fixed plates. The axial width of the roller and the gap between the front and rear adjacent rollers can be selected and set according to actual conditions.

[0009] Preferably, the roller conveyor belt and the supporting surface are both inclined, and the upstream end of the roller conveyor belt is higher than the downstream end of the roller conveyor belt.

[0010] By tilting the roller conveyor, gravity can be used to assist the sliding of food packaging bags, reduce jamming and improve circulation efficiency.

[0012] Through the above arrangement, the device of the present invention can be used for the circulation of food packaging bags of different sizes after plastic sealing; at least three roller conveyor belts are arranged to provide more support points, disperse the load, and reduce the wear of a single roller.

[0013] Preferably, the angle formed by the second roller conveyor belt and the third roller conveyor belt is greater than the angle formed by the first roller conveyor belt and the second roller conveyor belt. The flow path of the food packaging bag is further adjusted to ensure that the food packaging bag is smoothly transferred from the laminator to the conveyor belt.

[0014] Preferably, the roller conveyor belts are all fixed on a fixing seat, and the fixing seat has the baffle plates on both sides. By integrating the roller conveyor belts in the fixing seat, the stability during use is ensured, and the installation of the device of the present invention is facilitated.

[0015] Preferably, a receiving groove is formed between two adjacent roller conveyors, and the support pad is located in the receiving groove and supported on the upper side of the fixing seat. During actual installation, the setting and debugging of the roller conveyor can be completed first, and then a support pad of corresponding size can be selected according to the size of the space between the two adjacent roller conveyors, which is convenient for placing the support pad and cleaning the space between the two adjacent roller conveyors. The support pad can be made of a sheet metal.

[0016] Preferably, the fixing seat is fixed to the fixing part through the front bracket and the rear bracket, the front bracket is closer to the conveyor belt than the rear bracket, and the front bracket and the rear bracket are both provided with a strip matching groove extending in the up-down direction or a plurality of matching holes arranged at intervals up-down, and the strip matching groove or the matching hole are both provided with fasteners for fastening to the fixing part. The height and angle can be adjusted according to actual needs. The fixing part can be a production line frame, a fixed platform or even the ground.
