Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production line weighing, in particular to a weighing machine for a production line. Background Art
[0002] When producing food, strict requirements are imposed on the weight of each food, and then the relevant information is printed on the packaging bag, so that customers can check the relevant information when purchasing. For this reason, the food in each packaging bag needs to be weighed during production to prevent the weight from deviating from the normal value and affecting the reputation of the product. The weighing trays of existing weighing machines are all horizontal structures. If the food itself is irregular, when the food is placed at the corner during weighing, part of it will be suspended, which will cause weighing errors and affect the weighing results. Existing factories are all produced on assembly lines. In order to make weighing more accurate, the surface of the weighing machine needs to be kept still. After weighing is completed, the weighed food needs to be moved to another production line manually. Utility Model Content

DETAILED DESCRIPTION
[0016] In order to deepen the understanding and recognition of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described and introduced in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments, and are not intended to limit the embodiments in any form. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-4 The utility model provides a technical solution: a weighing machine for a production line, comprising a fixed base 1, a pressure sensor 2 is fixedly connected in the middle of the fixed base 1, a weighing block 3 is placed on the upper end of the pressure sensor 2, the weighing block 3 and the fixed base 1 are slidably connected, a control member 4 is fixedly connected to the upper end of the weighing block 3, a rotating member 7 is rotatably connected in the middle of the control member 4, a connecting plate 6 is fixedly connected to the upper end of the rotating member 7, a weighing disc 5 is fixedly connected to the upper end of the connecting plate 6, a sliding groove 8 is provided inside the control member 4, the sliding groove 8 is an arc-shaped structure, the sliding groove 8 is arranged along the side wall of the rotating member 7, a moving plate 9 is fixedly connected to the side end of the rotating member 7, and the moving plate 9 and the inner wall of the sliding groove 8 A first spring 10 is fixedly connected therebetween, a plug-in slot 12 is provided in the middle of the sliding slot 8, a limit plate 13 is inserted in the plug-in slot 12, a second spring 14 is fixedly connected between the lower end of the limit plate 13 and the inner wall of the plug-in slot 12, an auxiliary plate 15 is slidably connected in the middle of the sliding slot 8, a driving gear 11 is rotatably connected in the middle of the sliding slot 8, an extrusion slot 19 is provided in the middle of the limit plate 13, and a limit slot 18 is provided at the lower end of the rotating member 7. Food will fall from the previous conveying device onto the weighing plate 5. When weighing is completed, the weighing plate 5 and the connecting plate 6 rotate, so that the food on the weighing plate 5 falls onto the next conveying device, so that the food flowing on the production line can be weighed.
[0018] The rotating member 7 is a columnar structure, and a mounting opening is provided in the middle of the control member 4. The rotating member 7 is rotatably connected in the mounting opening. The opening width of the mounting opening is smaller than the diameter of the rotating member 7. After the food is weighed, the rotating member 7 can rotate in the middle of the control member 4. The mounting opening can limit the rotating member 7 to prevent the rotating member 7 and the control member 4 from moving during rotation.
[0019] The upper end of the weighing plate 5 is a V-shaped structure. There is a gap between the weighing plate 5 and the fixed base 1. Food dropped onto the weighing plate 5 will automatically move to the middle position of the weighing plate 5 due to gravity, thereby ensuring that the food is located in the middle position of the pressure sensor 2 to ensure the accuracy of weighing.
[0020] The auxiliary plate 15 is an arc-shaped structure, and a plurality of engaging teeth 16 are fixedly connected to the side end of the auxiliary plate 15. The distance between two adjacent engaging teeth 16 is the same. The driving gear 11 is meshed with the engaging teeth 16. When the food is weighed, the driving gear 11 rotates, and the driving gear 11 drives the auxiliary plate 15 to move through the meshing transmission. The auxiliary plate 15 can squeeze the movable plate 9, so that the rotating member 7 and the weighing plate 5 rotate together, causing the food on the weighing plate 5 to fall off. When the food on the weighing plate 5 falls off, the first spring 10 can drive the weighing plate 5 to reset and maintain a horizontal state.
[0021] Both ends of the auxiliary plate 15 pass through the limiting plate 13, and the auxiliary plate 15 is located in the middle of the extrusion groove 19. The side end of the auxiliary plate 15 is fixedly connected with an extrusion block 17, and the side end of the extrusion block 17 is an arc-shaped structure. When the auxiliary plate 15 moves, it drives the extrusion block 17 to move together, and the extrusion block 17 extrudes the limiting plate 13.
[0022] The openings on both sides of the limit groove 18 are arc-shaped structures. When the weighing disc 5 is in a horizontal state, the limit plate 13 is inserted into the limit groove 18. When the limit plate 13 is squeezed by the squeezing block 17, the limit plate 13 moves vertically downward, and the upper end of the limit plate 13 is disengaged from the limit groove 18, so that the rotating member 7 is released from the restriction and the rotating member 7 can rotate.
[0023] The food will fall from the previous conveying device onto the weighing plate 5. The upper end of the weighing plate 5 is a V-shaped structure. The food will automatically move to the middle position of the weighing plate 5 due to gravity, and ensure that the food is located in the middle position of the pressure sensor 2. When the food is weighed, the driving gear 11 drives the auxiliary plate 15 to move through the meshing transmission. At this time, the limit plate 13 is squeezed by the squeezing block 17, and the limit plate 13 moves vertically downward to compress and store force on the second spring 14. The upper end of the limit plate 13 is disengaged from the limit groove 18, and the auxiliary plate 15 continues to move. The auxiliary plate 15 can squeeze the movable plate 9 and compress and store force on the first spring 10, so that the rotating member 7 and the weighing plate 5 rotate together, so that the food on the weighing plate 5 falls onto the next conveying device.
[0024] Although the embodiments of the utility model have been shown and described, it should be emphasized that the above description is only an introduction and description of the use of the embodiments of the utility model, and does not limit the utility model in any form. For those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
