Description

TECHNICAL FIELD

[0001] The utility model relates to food packaging metering slitting technical field more specifically, relate to a kind of straight cutting formula material quantitative weighing equipment and river bean packaging production line. BACKGROUND

[0002] In prior art, the industrial production of river bean is to use river bean production equipment to produce continuous rice skin from rice pulp, and then cut the continuous rice skin to obtain strip-shaped river bean. The cutting of rice skin produced by river bean production equipment is divided into two modes: one is straight cutting mode, and the other is cross cutting mode. The straight cutting mode refers to vertical cutting along the conveying direction (length direction) of the rice skin, which divides the rice skin into several strip-shaped river beans. The length direction of the strip-shaped river bean after cutting is consistent with the conveying direction. The cross cutting mode refers to horizontal cutting perpendicular to the conveying direction of the rice skin (or the width direction of the rice skin), which divides the rice skin into several strip-shaped river beans. The length direction of the strip-shaped river bean after cutting is perpendicular to the conveying direction.

[0003] For the quantitative weighing of river beans with different cutting modes, the quantitative weighing equipment is also different, which is determined by the posture of the cut river bean. For example, the utility model patent with the name of "River bean weighing and sorting machine for precise weighing" and the authorization announcement date of May 14, 2024, and the authorization announcement number of CN220948785U. The river bean weighing and sorting machine disclosed in this utility model patent is suitable for river beans with cross cutting mode. The strip-shaped river beans are separated by the height difference between the material sorting conveying assembly and the first conveying belt. The first weighing assembly weighs a certain amount of several strip-shaped river beans. The river bean blocking assembly divides the river beans into piles. The second weighing assembly re-weighs the river beans. Finally, the river bean arrangement assembly arranges the river bean piles. In this utility model, the first weighing assembly measures the transmitted river beans. When the weight of the river beans suddenly increases, the first weighing device reduces the transmission speed to make the agglomerated river beans separate from each other by their own gravity at the edge of the first conveying belt, and to give enough time for the river bean blocking assembly to cut the river bean agglomerates. This utility model is only suitable for river beans with cross cutting mode, and is not suitable for straight cutting river beans. Straight cutting river beans are continuously conveyed. When the conveying speed of the first conveying belt decreases, the strip-shaped river beans will bend, which cannot match the output rate of the previous river bean production equipment.

[0004] For example, the authorization announcement date is July 24, 2020, the authorization announcement number is CN211076475U, and the name is "a straight cutting type vermicelli quantitative weighing machine". The utility model discloses a vermicelli quantitative weighing machine suitable for straight cutting type strip-shaped vermicelli, and its working principle is that the telescopic feeding table transports the straight cutting strip-shaped vermicelli, and the telescopic feeding table function is that after the cutting mechanism on the telescopic feeding table cuts off the vermicelli, it stretches out a distance along the vermicelli conveying direction to adapt to the continuous conveying of the straight cutting vermicelli, and then the telescopic feeding table retracts. The weighing table weighs the weight of the vermicelli dropped from the telescopic feeding table, and controls the cutting mechanism to cut off to form a vermicelli segment of a set weight. However, during the weighing of the weighing table, part of the vermicelli is located on the telescopic feeding table, and only after the vermicelli is cut off by the cutting mechanism, the vermicelli segment is located on the weighing table, which leads to the inaccuracy of the weight taken by the weighing table, and has a certain hysteresis.

[0005] The existing vermicelli production equipment cannot achieve consistent thickness when producing vermicelli, resulting in a change in the thickness of the produced vermicelli, which leads to the weight of the thicker vermicelli segment being lighter than the thinner vermicelli segment. When using the above straight cutting type vermicelli quantitative weighing machine for quantitative cutting, the weight error between the vermicelli segments is large, which does not meet the weight requirements of vermicelli packaging.

[0006] In addition, the above existing straight cutting type vermicelli quantitative weighing machine needs the telescopic feeding table to stretch and retract, cut off and cooperate, and the weighing table to weigh, which leads to a low cutting efficiency of the vermicelli. The cutting efficiency of the existing straight cutting type vermicelli quantitative weighing machine is about 1.7s-1.8s, which also cannot meet the efficiency requirements of vermicelli packaging.

Detailed Implementation

[0036] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Example 1

[0038] As a preferred embodiment of the utility model, refer to the description attached Figure 1 and attached Figure 2 , the embodiment discloses a kind of straight cutting formula material quantitative weighing equipment, which includes feed conveying section 100, first weighing conveying section 200, cutting conveying section 300, transition conveying section 400 and second weighing conveying section 500;

[0039] The first weighing conveying section 200 is arranged between the feed conveying section 100 and the cutting conveying section 300, configured to continuously weigh the material conveyed to the cutting conveying section 300;The first weighing conveying section 200 includes a first conveying assembly 201 and a first weighing sensor for weighing the material conveyed by the first conveying assembly 201;The cutting conveying section 300 includes a second conveying assembly 301 and a servo cutting assembly 302 for cutting the material conveyed by the second conveying assembly 301;The conveying speeds of the feed conveying section 100, the first weighing conveying section 200 and the cutting conveying section 300 are the same.

[0040] The transition conveying section 400 is arranged between the cutting conveying section 300 and the second weighing conveying section 500, configured to receive the material conveyed by the cutting conveying section 300 at a first speed matching the conveying speed of the cutting conveying section 300, and after the cutting conveying section 300 cuts the material and forms a material segment, convey the material segment to the second weighing conveying section 500 at a second speed matching the conveying speed of the second weighing conveying section 500;The second speed is greater than the first speed;The second weighing conveying section 500 is configured to weigh the material segment formed after the cutting of the cutting conveying section 300.

[0041] In the embodiment, the straight cutting formula material quantitative weighing equipment can be directly connected to the river bean noodle production equipment, and the river bean noodle production equipment outputs the straight-cut strip-shaped river bean noodle bundle, i.e. vertically cuts the river bean noodle along the length direction to obtain multiple parallel river bean noodles, which are collected into a bundle and output. The river bean noodle bundle formed by the multiple strip-shaped river bean noodles output by the river bean noodle production equipment is directly conveyed by the feed conveying section 100 of the straight cutting formula material quantitative weighing equipment of the present application, then conveyed through the first weighing conveying section 200 and weighed, and then input to the cutting conveying section 300.

[0042] When the straight-cut material quantitative weighing device is started, the conveying speeds of the feeding conveying section 100, the first weighing conveying section 200 and the cutting conveying section 300 are matched with the output speed of the rice noodle production device; the feeding conveying section 100, the first weighing conveying section 200 and the cutting conveying section 300 keep conveying the rice noodle bundle output by the rice noodle production device at a constant speed; the length of the rice noodle section reaching the set weight is obtained according to the weight value weighed by the first weighing conveying section 200 and the conveying speed of the rice noodle bundle, the cutting assembly on the cutting conveying section 300 is controlled to cut the rice noodle, and a rice noodle section meeting the set weight is formed; the cut rice noodle section is accelerated by the transition conveying section 400 and conveyed to the second weighing conveying section 500, the second weighing conveying section 500 precisely weighs the rice noodle section, and the error between the set weight and the weighed weight is obtained; when there is a large error, the cutting gap of the cutting assembly is adjusted; through the test of two rice noodle sections, the cutting gap of the cutting assembly is precisely adjusted, and the dynamic precision of the weighing device of the application can reach ±15g in the test of a single rice noodle section with a weight of 250g. In the subsequent quantitative weighing process, the first weighing conveying section 200 continuously weighs the conveyed rice noodle bundle; when the weight of the rice noodle bundle fluctuates greatly (if the weight decreases, it means that the thickness of the rice noodle bundle is thin, and if the weight increases, it means that the thickness of the rice noodle bundle is thick), the cutting gap of the cutting assembly is adjusted according to the weighing data of the first weighing conveying section 200, and then the second weighing conveying section 500 precisely re-weighs to confirm whether there is an error; if there is no error, the cutting gap adjusted by the first weighing conveying section 200 is used; if there is an error, the cutting gap of the cutting assembly is fine-tuned, so that the rice noodle is weighed at high precision and high speed, and the weighing precision and efficiency of the rice noodle quantitative weighing device are improved.

[0043] In the above process, the first weighing conveying section 200 continuously monitors the weight change of the rice noodle bundle, so as to adjust the cutting gap of the servo cutting assembly 302 on the cutting conveying section 300, the second weighing conveying section 500 precisely weighs the cut rice noodle section and feeds back the weighed weight to the front end (the first weighing conveying section 200 and the cutting conveying section 300) to adjust the cutting gap of the servo cutting assembly 302 in the cutting conveying section 300, so as to change the length of the cut rice noodle section, thereby ensuring that the weight of each rice noodle section can be precisely controlled; the precision of the rice noodle quantitative weighing device of the application can reach ±15g for a rice noodle section with a weight of 250g, which can be precisely weighed within the packaging error range; compared with the prior art straight-cut rice noodle quantitative weighing machine, the weight of the rice noodle section is more accurate.

[0044] In the embodiment, the first weighing conveying section 200 and the cutting conveying section 300 are independent of each other, and the operation of the cutting conveying section 300 does not affect the weighing accuracy of the first weighing conveying section 200. If the first weighing conveying section 200 and the cutting conveying section 300 are the same conveying section, the action of the servo cutting assembly 302 on the cutting conveying section 300 will affect the weighing each time. Therefore, the first weighing conveying section 200 and the cutting conveying section 300 are independently arranged and do not affect each other.

[0045] Compared with the prior art, the embodiment adds a transition conveying section 400 between the cutting conveying section 300 and the second weighing conveying section 500, wherein the transition conveying section 400 is a variable-speed conveying belt. After receiving the vermicelli section cut by the cutting conveying section 300, the transition conveying section 400 accelerates the conveying to the second weighing conveying section 500, thereby shortening the time for the vermicelli section to be conveyed to the second weighing conveying section 500. The prior art directly arranges the weighing conveying section after the cutting conveying section 300. When not cutting, the conveying speed of the weighing conveying section matches the conveying speed of the front conveying section. After cutting, the conveying speed is accelerated to the next section. This results in a long weighing process after the cutting conveying section 300, reduces the efficiency, and affects the weighing accuracy when the weighing conveying section accelerates the conveying, thereby causing the weighing accuracy to decrease. The variable-speed transition conveying section 400 between the cutting conveying section 300 and the second weighing conveying section 500 can solve these problems.

[0046] As an example of the embodiment, the above-mentioned feeding conveying section 100, the first conveying assembly 201, the second conveying assembly 301, the transition conveying section 400, and the second weighing conveying section 500 can adopt a conventional conveying belt structure. The transition conveying section 400 needs to change speed, and a servo motor assembly is used to drive the transition conveying section 400 to adapt to the speed change. The second weighing conveying section 500 is provided with a second weighing sensor to facilitate weighing.

[0047] The feeding conveying section 100, the first conveying assembly 201, and the second conveying assembly 301 are uniform-speed conveying, and therefore a conventional motor can be used to drive the feeding conveying section 100, the first conveying assembly 201, and the second conveying assembly 301. Alternatively, a servo motor can be used to drive the feeding conveying section 100, the first conveying assembly 201, and the second conveying assembly 301.

[0048] Embodiment 2

[0049] As another preferred embodiment of this utility model, this embodiment further supplements and elaborates on the technical solution of this utility model based on the above embodiment 1. In this embodiment, when the servo cutting component 302 in the cutting and conveying section 300 cuts the material, there is a set distance between the contact position of the servo cutting component 302 and the conveying end of the second conveying component 301. By controlling this set distance, after the servo cutting component 302 cuts the rice noodles into rice noodle segments, the transition conveying section 400 can immediately accelerate to convey the rice noodle segments to the second weighing conveying section 500. The reserved set distance allows the transition conveying section 400 to continue receiving new rice noodles while accelerating the conveying of the rice noodle segments. After the transition conveying section conveys the rice noodle segments to the second weighing conveying section 500, it immediately slows down to match the speed of the cutting and conveying section 300. At this time, the continuously conveyed rice noodles have just passed the set distance and entered the transition conveying section 400. This makes the material reception between the transition conveying section 400 and the cutting conveying section 300 smoother, avoiding wear on the rice noodle bundles caused by the speed difference between the transition conveying section 400 and the subsequently conveyed rice noodle bundles.

[0050] Furthermore, a support mounting bracket 303 is provided on the cutting and conveying section 300, the servo cutting component 302 is mounted on the support mounting bracket 303, and the support mounting bracket 303 is mounted on the frame of the second conveying component 301.

[0051] As another example of this embodiment, a rotating servo cutting assembly 302 can be used. When cutting rice noodles, the linear velocity of the cutting blade of the servo cutting assembly 302 is greater than the conveying speed of the second conveying assembly 301. This separation of the cut rice noodle segments from the rice noodle bundles is achieved through the cutting blade, preventing sticking. A certain amount of time is provided for the speed transition of the transition conveying section 400. Specifically, its structure is as follows (not shown in the figure): the servo cutting assembly 302 includes a cutting servo motor assembly, a cutting blade, and a transmission assembly. The cutting servo motor drives the cutting blade through the transmission assembly to perform the cutting operation on the material conveyed on the second conveying assembly 301. The transmission assembly is a drive shaft, and the cutting blade is mounted on the drive shaft. The output shaft of the cutting servo motor assembly is connected to the drive shaft, driving the cutting blade to rotate.

[0052] As another example of the embodiment, the servo cutter assembly can adopt a straight cutting method to cut the rice noodles, and has the structure (not shown in the figure): the servo cutter assembly 302 includes a cutting servo motor assembly, a cutting knife and a transmission assembly. The cutting servo motor drives the cutting knife to move through the transmission assembly to cut the material conveyed on the second conveying assembly 301. The transmission assembly includes a crank and a connecting rod. The cutting knife is slidably assembled on the support mounting bracket 303 through the cutting knife mounting seat. One end of the crank is connected with the output shaft of the cutting servo motor assembly. One end of the connecting rod is hinged to the other end of the crank, and the other end of the connecting rod is hinged to the cutting knife mounting seat.

[0053] Embodiment 3

[0054] As another preferred embodiment of the utility model, the embodiment is a further detailed supplement and elaboration of the technical solution of the utility model on the basis of the above-mentioned embodiment 1 or embodiment 2. In the embodiment, referring to the drawings in the specification Figure 1 and the drawings, the device further includes a discharge conveying section 600, which is arranged at the tail end of the second weighing conveying section 500 and is configured to receive the material conveyed by the second weighing conveying section 500. Figure 2

[0055] As an example of the embodiment, the discharge conveying section 600 can serve as the feeding tail rack of a subsequent packaging machine, and the material conveyed by the discharge conveying section 600 is directly input into the packaging machine for film wrapping.

[0056] As another example of the embodiment, the discharge conveying section 600 is a telescopic conveying belt, and the telescopic end of the telescopic conveying belt is located at the output end of the discharge conveying section 600. The telescopic conveying belt is used as the discharge conveying section 600, which cooperates with the feeding tail rack of the subsequent packaging machine to realize the stacking or folding of the rice noodle section. The stacking of the rice noodle section is realized by the rapid retraction of the telescopic conveying belt, so that the rice noodle section falls into the lower layer feeding tail rack and is stacked to a set number of sections or a set weight before being input into the packaging machine for packaging. The folding of the rice noodle section refers to that when the front end of the telescopic conveying belt contacts the lower layer feeding tail rack, the telescopic conveying belt is extended, and when the extension stroke is half of the rice noodle section, the telescopic conveying belt is rapidly retracted, so that the second half of the rice noodle section is folded on the first half, the folding of the rice noodle section is completed, and the folded rice noodle section is input into the packaging machine for packaging.

[0057] ​As another example of this embodiment, the device further includes a stacking conveyor section, which is located below the discharge conveyor section 600, with its front end positioned below the telescopic end of the discharge conveyor section 600. Considering that the feeding tailstock of the packaging machine provides continuous and uninterrupted transport during machine operation, a stacking conveyor section is added. This stacking conveyor section can remain stationary and inactive while the rice noodle segments are stacked or folded. Once stacking or folding is complete, its speed is increased to match that of the feeding tailstock of the packaging machine, feeding the stacked or folded rice noodles into the feeding tailstock of the packaging machine to complete the packaging process.
