Description

Technical Field

[0001] The utility model relates to a weighing component on a packaging machine, in particular to a anti-shattering multi-head belt scale. Background Art

[0002] Frozen fresh food generally has a layer of ice coat on its surface. During the process of packing into boxes, workers need to carefully place the frozen fresh food into the packing box. Once placed randomly, the ice coat of the fresh food will be damaged, which will lead to the food being extremely polluted and deteriorated. For example, for frozen crayfish, when they are alive, they are quickly frozen by liquid nitrogen to form an ice coat on their surface. When these ice coats fall from a relatively large height, they will be damaged. Especially during the packing process, more attention needs to be paid. The existing packing method is to use manual means in order not to damage the ice coat. Although it can prevent the frozen ice coat from being damaged, the work efficiency is low, the labor intensity is high, and it is difficult to meet the needs of mass production. Summary of the Utility Model

[0003] In order to solve the above problems, the purpose of the utility model is to provide an anti-shattering multi-head belt scale that can place frozen fresh food into the packing box with a small drop and accurately weigh it, so as to avoid the damage of the ice coat of the frozen fresh food.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An anti-shattering multi-head belt scale, including a frame body. The frame body is sequentially provided with a material input mechanism, a lane control and material output mechanism, and a weighing platform from top to bottom in an inclined direction. The material input mechanism, the lane control and material output mechanism, and the weighing platform are respectively electrically connected to a control host. A weighing sensor is arranged at the bottom of the weighing platform. An open-up packing box is placed on the weighing platform. The discharge channel of the material input mechanism is connected to the inlet of the lane control and material output mechanism. The outlet of the lane control and material output mechanism is close to the upper opening of the packing box. The lane control and material output mechanism includes a number of limiting blocks arranged horizontally and sequentially on the frame body. Sliding grooves that are inclined up and down are respectively formed between the limiting blocks and between the limiting blocks and the side plate of the frame body. The number of the weighing platforms corresponds to the number of the sliding grooves one by one. In the sliding groove, wide conveyor belts and narrow conveyor belts that are inclined and parallel are arranged. The wide conveyor belts and the narrow conveyor belts are respectively controlled by independent first motors. A material control baffle is arranged at the outlet position of the wide conveyor belt. The material control baffle is driven by a cylinder to stretch up and down. The height of the narrow conveyor belt is greater than the height of the wide conveyor belt. The outlets of the wide conveyor belts and the narrow conveyor belts are connected with a downward-inclined material guiding groove plate. A first baffle is arranged at the outlet position of the material guiding groove plate. A gap between the first baffle and the bottom of the material guiding groove plate forms an output port, and the output port is close to the upper opening of the packing box.

[0005] The material input mechanism includes second baffle plates erected front and back. Between the two second baffle plates, a first conveyor belt and a second conveyor belt are arranged vertically. The first conveyor belt and the second conveyor belt are arranged obliquely and flatly and are respectively controlled by independent second motors. The conveying directions of the first conveyor belt and the second conveyor belt are opposite. Partition plates are respectively arranged at the front and rear ends of the first conveyor belt and the second conveyor belt. The gap between the second baffle plate and the second conveyor belt forms the discharge channel.

[0006] The cross-section of the limiting block is in the shape of an isosceles triangle.

[0007] The beneficial effects of the present invention are as follows: After the frozen fresh food is poured into the material input mechanism, it is sorted and output to the lane control and material output mechanism, and is output to the weighing platform through the wide conveyor belt in the lane control and material output mechanism for timely weighing. When the weight in the packing box is almost close to the weight set by the control host for the weighing platform, the material control baffle moves down to block the material on the wide conveyor belt. At this time, the material is output through the narrow conveyor belt for supplementary feeding of the material, so that the weight in the packing box accurately reaches the weighing weight set by the control host. Since the material input mechanism, the lane control and material output mechanism, and the weighing platform are inclined from top to bottom, the height of the material can be gradually reduced during the conveying process. When entering the packing box, the drop is very small. In this way, the technical effect of putting the frozen fresh food into the packing box with a small drop and accurately weighing is achieved, thereby avoiding the damage of the ice coat of the frozen fresh food.

[0008] The following further describes the present invention in conjunction with the drawings and specific embodiments. Description of the Drawings

[0009] Figure 1 is a three-dimensional view of the specific embodiment of the present invention;

[0010] Figure 2 is Figure 1 the enlarged view of A in Specific Embodiments

[0011] The following specifically describes the present invention through embodiments, which is only used for further illustration of the present invention and cannot be construed as a limitation on the protection scope of the present invention.

[0012] Such as Figure 1 、 Figure 2As shown in the figure, this embodiment discloses a multi-head anti-break belt weigher, which includes a frame body 1. The frame body 1 is sequentially provided with a material input mechanism 2, a lane control material output mechanism 3, and a weighing platform 4 in a downwardly inclined direction from top to bottom. The material input mechanism 2, the lane control material output mechanism 3, and the weighing platform 4 are respectively electrically connected to a control host. A weighing sensor is configured at the bottom of the weighing platform 4. A packing box 5 with an upward opening is placed on the weighing platform 4. The discharge channel of the material input mechanism 2 is connected to the inlet of the lane control material output mechanism 3, and the outlet of the lane control material output mechanism 3 is close to the upper opening of the packing box 5. The lane control material output mechanism 3 includes four limiting blocks 31 arranged horizontally on the frame body 1 in sequence. Five sliding grooves 32 that are inclined up and down are respectively formed between the limiting blocks 31 and between the limiting blocks 31 and the side plate of the frame body 1. The number of weighing platforms 4 corresponds to the number of sliding grooves 32 one by one. An inclined and parallel wide conveyor belt 33 and a narrow conveyor belt 34 are arranged in the sliding groove 32. The width of the narrow conveyor belt 34 is equivalent to the width of one material. The function of the narrow conveyor belt 34 is for supplementary feeding. The wide conveyor belt 33 and the narrow conveyor belt 34 are respectively controlled by independent first motors. A material control baffle 35 is arranged at the outlet position of the wide conveyor belt 33. The material control baffle 35 is driven to move up and down by a cylinder 36. The cylinder 36 is installed on a straight rod and is connected to an air pump through a solenoid valve. The height of the narrow conveyor belt 34 is greater than the height of the wide conveyor belt 33. The outlets of the wide conveyor belt 33 and the narrow conveyor belt 34 are connected with a downwardly inclined material guiding trough plate 37. A first baffle 38 is configured at the outlet position of the material guiding trough plate 37. The gap between the first baffle 38 and the bottom of the trough of the material guiding trough plate 37 forms an outlet, and this outlet is close to the upper opening of the packing box 5.

[0013] The material input mechanism 2 includes second baffle plates 21 erected front and back. A first conveyor belt 22 and a second conveyor belt 23 are arranged up and down between the two second baffle plates 21. The first conveyor belt 22 and the second conveyor belt 23 are arranged in an inclined and flat manner and are respectively controlled by independent second motors 20. The conveying directions of the first conveyor belt 22 and the second conveyor belt 23 are opposite. Partition plates 24 are respectively arranged at the front and rear ends of the first conveyor belt 22 and the second conveyor belt 23. The partition plates 24 are inserted and cooperatively connected with the card slots on the two second baffle plates. The gap between the second baffle plate 21 and the second conveyor belt 23 forms a discharge channel 25. After the material is poured onto the first conveyor belt 22 and the second conveyor belt 23, due to the opposite conveying directions of the first and second conveyor belts, the material can be laid more evenly on the first and second conveyor belts, and then slide out from the inclined second conveyor belt 23 below through the discharge channel and enter each sliding groove 32 in the lane control material output mechanism 3 in an orderly manner.

[0014] The cross-section of the limiting block 31 is in an isosceles triangle shape. In this way, the sliding groove 32 can have a wider edge protection, making it more convenient for the material (frozen fresh food) to pass through.

[0015] The first conveyor belt 22, the second conveyor belt 23, the wide conveyor belt 33, the narrow conveyor belt 34 and the material guiding trough plate 37 form a channel for the inclined conveying of materials, gradually reducing the height difference with the packing box 5, and avoiding damaging the ice coat of the frozen fresh food due to too large a height difference when falling into the packing box 5.

[0016] With the above technical solution, after the frozen fresh food is poured into the material input mechanism 2, it is sorted and output to the lane control and material output mechanism 3, and is output to the weighing platform 4 through the wide conveyor belt 33 in the lane control and material output mechanism 3 for weighing in a timely manner. When the weight in the packing box 5 is approaching the weight set by the control host for the weighing platform 4, the material control baffle 35 moves down to block the materials on the wide conveyor belt 33. At this time, the materials are output through the narrow conveyor belt 34 for supplementary feeding, so that the weight in the packing box 5 accurately reaches the weighing weight set by the control host. Since the material input mechanism 2, the lane control and material output mechanism 3 and the weighing platform 4 are inclined from top to bottom, the height of the materials can be gradually reduced during the conveying process. When entering the packing box 5, the height difference is very small, thus achieving the technical effect of putting the frozen fresh food into the packing box 5 with a small height difference and accurate weighing, thereby avoiding material breakage and also avoiding damage to the ice coat when the material is frozen fresh food.

[0017] The controlled components such as the second motor in the material input mechanism 2, the first motor in the lane control and material output mechanism 3, the solenoid valve and the weighing sensor on the weighing platform 4 are all controlled by the control host (the host includes components such as a processor, a touch screen, and a sensor) through a program.
