Description

Technical Field

[0001] This utility model relates to the field of food weighing technology, specifically to a durian counterweight weighing platform. Background Art

[0002] Durian, a giant tropical evergreen tree belonging to the Malvaceae order and Bombacaceae family, has oblong leaves with pointed tips. It bears pale yellow flowers in cymose inflorescences. The fruit is about the size of a football, with a hard rind covered in triangular thorns. The flesh consists of arils, which are pale yellow, sticky, and juicy. It is a fruit of high economic value. Durian is one of the most famous tropical fruits, originating in Malaysia. It is widely cultivated in Southeast Asian countries, with Thailand being the largest producer. It is also grown in Guangdong and Hainan provinces of China. Durian is most famous in Thailand, where it is known as the "King of Fruits." Its aroma is strong; those who love it praise its fragrance, while those who dislike it complain of its stench.

[0003] Because durian flesh varies in size and weight after pitting, directly packaging each box according to the amount of flesh would result in significant weight discrepancies, making it inconvenient for uniform sales or subsequent processing. Therefore, it is necessary to counterweight the durians within each box to ensure a consistent weight across all packages. Traditionally, durian counterweighting and packaging is done manually, where each durian is weighed and then distributed according to its weight to maintain a relatively uniform weight. However, manual weighing is slow and labor-intensive. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to invent a durian counterweight weighing platform that can distribute weight quickly and effectively reduce labor costs.

[0005] The present invention adopts the following technical solution:

[0006] A durian counterweight weighing platform includes a weighing platform body, a counterweight mechanism, and a weighing mechanism. The counterweight mechanism includes a counterweight arm, a receiving cylinder, a drive base, a sealing unit, a drive unit, and a first weighing sensor. The drive unit is mounted on the weighing platform body, and the drive end of the drive unit is connected to the drive base to drive the drive base to rotate. One end of the counterweight arm is connected to the drive base, and the other end is connected to the receiving cylinder. The top of the receiving cylinder has an inlet, and the bottom of the receiving cylinder has an outlet. The sealing unit is adapted to block the outlet. The first weighing sensor is adapted to weigh the weight of the food falling into the receiving cylinder.

[0007] The weighing mechanism includes multiple weighing units, which are arranged in a circular array around the drive seat. Each weighing unit includes two parallel fixed seats, a weighing hopper disposed between the two fixed seats, and a second weighing sensor for measuring the weight of the food in the weighing hopper.

[0008] Furthermore, the sealing unit includes a baffle slidably connected to the counterweight arm, a drive gear set rotatably mounted on the counterweight arm, and a first drive motor mounted on the counterweight arm. The drive end of the first drive motor is equipped with a drive gear, which is connected to the drive gear set. The baffle is provided with a rack that is connected to the drive gear set, so as to allow the first drive motor to drive the baffle to reciprocate along the length of the counterweight arm through the drive gear set, thereby opening or closing the discharge port.

[0009] Furthermore, the baffle is provided with a mounting groove, the first weighing sensor is installed in the mounting groove, and the first weighing sensor is provided with an anti-collision pad.

[0010] Furthermore, the fixed base is provided with a receiving cavity, and a spring and a pressure plate are provided in the receiving cavity. A sliding groove is opened on one side of the fixed base facing each other, and the sliding groove communicates with the receiving cavity. Connecting rods are provided at both ends of the weighing hopper. The connecting rods extend into the sliding groove and are hinged to the pressure plate. The cross-section of the connecting rod is elliptical. The width of the sliding groove is adapted to the width of the connecting rod. A notch is provided on the sliding groove. When the connecting rod slides to the notch, the connecting rod is adapted to rotate relative to the sliding groove under the action of the gravity of the weighing hopper to slide into the notch. The notch is arc-shaped.

[0011] Furthermore, a coil spring is provided at the connection end between the connecting rod and the pressure plate.

[0012] Furthermore, a guide hopper is also installed on the receiving cylinder.

[0013] Furthermore, the second weighing sensor is disposed at the bottom of the weighing hopper, and a weighing plate is disposed on the second weighing sensor.

[0014] Beneficial effects:

[0015] This invention utilizes a combination of a first and a second weighing sensor to enable the receiving cylinder to select a suitable weighing hopper for counterweighting based on the weight of the durian. This ensures that the weight of the durians transported by the weighing hopper remains within a consistent range, preventing significant discrepancies. Consequently, it replaces manual weighing and counterweighting, effectively improving counterweighting efficiency while reducing labor costs. Attached Figure Description

[0029] like Figure 1-7 As shown, a durian counterweight weighing platform includes a weighing platform body 10, a counterweight mechanism 20, and a weighing mechanism. The counterweight mechanism 20 includes a counterweight arm 201, a receiving cylinder 202, a drive seat 203, a sealing unit 204, a drive unit 205, and a first weighing sensor 206. The drive unit 205 is mounted on the weighing platform body 10, and the drive end of the drive unit 205 is connected to the drive seat 203 to drive the drive seat 203 to rotate. One end of the counterweight arm 201 is connected to the drive seat 203, and the other end is connected to the receiving cylinder 202. The top of the receiving cylinder 202 has an inlet, and the bottom of the receiving cylinder 202 has an outlet. The sealing unit 204 is adapted to block the outlet. The first weighing sensor 206 is adapted to weigh the weight of the food falling into the receiving cylinder 202.

[0030] The weighing mechanism includes multiple weighing units 301, which are arranged in a circular array around the drive seat 203. Each weighing unit 301 includes two parallel fixed seats 3011, a weighing hopper 3012 disposed between the two fixed seats 3011, and a second weighing sensor 3013 for measuring the weight of food in the weighing hopper 3012.

[0031] When using this utility model, the pitted durian falls into the receiving cylinder 202. The first weighing sensor 206 weighs the durian falling into the receiving cylinder 202 and transmits the weight of the durian to the control terminal. Based on the weight information of the durian transmitted by the first weighing sensor 206, the control terminal controls the drive unit 205 to drive the drive seat 203 to rotate, so that the receiving cylinder 202 is moved above the appropriate weighing hopper 3012 through the counterweight arm 201. Then, the sealing unit 204 is controlled to open the receiving cylinder 202 so that the durian in the receiving cylinder 202 falls into the weighing hopper 3012. The second weighing sensor 3013 weighs the durian falling into the weighing hopper 3012 until it reaches the preset range. Then, the weighing hopper 3012 discharges the durian for packaging.

[0032] Specifically, during the counterweighting process, the durian falls into the receiving cylinder 202. The first weighing sensor 206 detects the weight of the durian in the receiving cylinder 202 and transmits the weight information to the control terminal. The control terminal calculates the weight information of the durian received from the first weighing sensor 206 and the weight information of the durian in the weighing hopper 3012 received from the second weighing sensor 3013. When the sum of the weight information of the durian received from the first weighing sensor 206 and the weight of the durian in one of the weighing hoppers 3012 reaches a preset range, the control terminal controls the drive. Unit 205 drives drive base 203 to rotate, so that counterweight arm 201 drives receiving cylinder 202 to move directly onto weighing hopper 3012, and controls sealing unit 204 to open to transfer durian onto weighing hopper 3012. If the durian weight information returned by first weighing sensor 206 is within a preset range or exceeds the preset range when added with the weight of durian in weighing hopper 3012, then control terminal controls receiving cylinder 202 to move above any empty weighing hopper 3012 to transfer durian into weighing hopper 3012.

[0033] This invention utilizes a first weighing sensor 206 and a second weighing sensor 3013 to work together, enabling the receiving cylinder 202 to select a suitable weighing hopper 3012 for counterweighting based on the weight of the durian. This ensures that the weight of the durians conveyed by the weighing hopper 3012 remains within a consistent range without significant discrepancies, thereby replacing manual weighing and counterweighting, effectively improving counterweighting efficiency, and reducing labor costs.

[0034] In addition, to reduce the impact of the durian falling from the receiving cylinder 202 onto the weighing hopper 3012, the distance between the receiving cylinder 202 and the weighing hopper 3012 can be shortened, thereby reducing the distance the durian falls and reducing the impact.

[0035] Specifically, in this embodiment, the sealing unit 204 includes a baffle 2041 slidably connected to the counterweight arm 201, a drive gear set rotatably mounted on the counterweight arm 201, and a first drive motor 2042 mounted on the counterweight arm 201. The drive end of the first drive motor 2042 is equipped with a drive gear 2043, which is connected to the drive gear set. The baffle 2041 is provided with a rack 2044 that is connected to the drive gear set, so that the first drive motor 2042 can drive the baffle 2041 to reciprocate along the length of the counterweight arm 201 through the drive gear set, thereby opening or closing the discharge port.

[0036] During operation, the control terminal controls the first drive motor 2042 to start, which drives the rack 2044 to move through the drive gear set, so that the baffle 2041 moves along the length of the counterweight arm 201, so that it can move toward or away from the receiving cylinder 202. When moving toward the receiving cylinder 202, the baffle 2041 can block the discharge port of the receiving cylinder 202, while when moving away from the receiving cylinder 202, the baffle 2041 can open the discharge port of the receiving cylinder 202.

[0037] In order to facilitate the weighing of durian in the receiving cylinder 202 by the first weighing sensor 206, an installation groove is provided on the baffle 2041 in this embodiment. The first weighing sensor 206 is installed in the installation groove. When the durian falls into the receiving cylinder 202, the durian will fall directly above the first weighing sensor 206. The first weighing sensor 206 can directly weigh the durian. In order to avoid the durian directly hitting the first weighing sensor 206 and causing it to be damaged, a shock-absorbing pad is provided on the first weighing sensor 206.

[0038] In addition, in order to facilitate the weighing of durians in the symmetrical weighing hopper 3012, in this embodiment, the second weighing sensor 3013 is set at the bottom of the weighing hopper 3012, and a weighing plate is set on the second weighing sensor 3013.

[0039] Preferably, in this embodiment, the fixed base 3011 is provided with a receiving cavity, and a spring 3015 and a pressure plate are disposed in the receiving cavity. The second weighing sensor 3013 is disposed between the spring 3015 and the pressure plate. A sliding groove 3016 is provided on one side of the fixed base 3011, and the sliding groove 3016 communicates with the receiving cavity. Connecting rods 3014 are provided at both ends of the weighing hopper 3012, and the connecting rods 3014 extend into the sliding groove 3016. The connecting rod 3014 is hinged to the pressure plate. The cross-section of the connecting rod 3014 is elliptical. The width of the sliding groove 3016 is adapted to the width of the connecting rod 3014. The sliding groove 3016 is provided with a notch 3017. When the connecting rod 3014 slides to the notch 3017, the connecting rod 3014 is adapted to rotate relative to the sliding groove 3016 under the gravity of the weighing hopper 3012 to slide into the notch 3017. The notch 3017 is arc-shaped.

[0040] In this embodiment, since the width of the chute 3016 is adapted to the width of the connecting rod 3014, when the connecting rod 3014 slides along the chute 3016, the chute wall of the chute 3016 will restrict the rotation of the connecting rod 3014, thereby preventing the weighing hopper 3012 from rotating and unloading. Only when the weight of the durian in the weighing hopper 3012 reaches the minimum value of the preset range, the spring 3015 is compressed to the notch 3017 position. At this time, the chute wall of the chute 3016 no longer restricts the rotation of the connecting rod 3014, so the weighing hopper 3012 can tilt and reverse under the action of gravity to complete the unloading.

[0041] Specifically, since the elastic force of spring 3015 is related to the amount of compression, in this embodiment, spring 3015 can be set such that when compressed to the position of notch 3017, its elastic force is equal to or slightly greater than the sum of the preset minimum weight of durian and the weight of weighing hopper 3012. By adopting this setting, it is possible to avoid the weighing hopper 3012 from flipping over to unload when the weight of durian has not reached the predetermined range. After unloading, spring 3015 rebounds, and connecting rod 3014 will move upward to reset. Since the cross-section of connecting rod 3014 is elliptical and notch 3017 is an arc shape that matches the cross-section of connecting rod 3014, during the upward movement of connecting rod 3014, connecting rod 3014 can slide and guide along the arc surface of notch 3017 to return to the slide groove 3016 without being stuck by notch 3017.

[0042] Furthermore, to facilitate the quick sliding of the connecting rod 3014 into the slide groove 3016, in this embodiment, a coil spring is provided at the connection end between the connecting rod 3014 and the pressure plate. The coil spring is able to deform when the weighing hopper 3012 reverses and quickly rebound after the weighing hopper 3012 unloads material, thereby enabling the connecting rod 3014 to quickly slide back into the slide groove 3016 along the notch 3017.

[0043] Specifically, in order to facilitate the receiving cylinder 202 in receiving durians, in this embodiment, a guide hopper 2021 is also installed on the receiving cylinder 202.

[0044] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
