[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a building material packaging and weighing device, comprising a support frame, a top plate is fixedly connected to the top surface of the support frame, a hopper is fixedly connected to the middle position of the top plate, a cylinder is fixedly connected to the front side of the hopper, a material unloading weighing mechanism is arranged below the hopper, a transmission mechanism is arranged below the material unloading weighing mechanism, a table plate is fixedly connected to the middle part of the inner side of the support frame, a packaging mechanism is arranged on the bottom surface of the table plate, a bottom frame is fixedly connected to the inner bottom end of the support frame, a transport platform is fixedly connected to the top surface of the bottom frame, and a plurality of rollers are installed on the bottom surface of the transport platform;

[0006] According to the above technical scheme, the material discharge weighing mechanism includes a material discharge chute, which is fixedly connected to the bottom surface of the hopper, and the front and rear sides of the material discharge chute are fixedly connected with side sealing plates, and two material control side plates are hingedly connected between the two side sealing plates, and the top of each material control side plate is fixedly connected with a limiting plate, and the end of the material control side plate away from the limiting plate is fixedly connected with a sealing plate, and the side of the material control side plate away from the material discharge chute is fixedly connected with a deflection slot plate, and the inner side of the deflection slot plate is slidably connected with a slide slot rod, and the front and rear ends of the slide slot rod are fixedly connected with vertical connecting rods.

[0007] According to the above technical solution, the bottom end of the vertical connecting rod is fixedly connected with a hanging plate, the top surface of the hanging plate is slidably connected with a weighing plate, the bottom surface of the weighing plate is fixedly connected with a gravity sensor, the hopper passes through the top surface of the top plate to the bottom surface, the bottom end of the cylinder is fixedly connected with a fixed rod plate, and the fixed rod plate is fixedly connected to the slide rod, the bottom surface of the weighing plate is provided with an elastic spring, and the two ends of the elastic spring are respectively fixedly connected to the weighing plate and the hanging plate, the material limiting plate and the lower chute are fitted with each other, in the initial state, the material in the hopper enters between the two material controlling side plates through the lower chute, so that the material fills the inside of the material controlling side plates, and when the bag is located directly below the sealing plate, the cylinder is moved upward When the cylinder contracts, the slide rod is pushed upward through the fixed rod plate, so that the slide rod pushes the deflection slot plate to deflect around the node where the sealing plate and the side sealing plate are connected. After the deflection slot plate is deflected, the sealing plates are moved away from each other, and the limiting plate connected to the deflection slot plate is fitted to the side of the top chute to slide and seal the top of the chute, so that the material in the material control side plate falls into the bag through the bottom of the sealing plate to prevent the material in the hopper from continuing to fall, ensuring the uniformity of the bag loading weight. At the same time, when the cylinder contracts upward, the slide rod moves upward to drive the connected hanging plate to lift up, so that the weighing plate on the hanging plate contacts the bottom of the bag, and as the weighing plate rises, the weight of the material loaded in the bag is weighed by the bottom gravity sensor.

[0008] According to the above technical scheme, the transmission mechanism includes a transverse guide wheel, and there are six transverse guide wheels, which are rotatably connected to the upper surface of the table, a chain is arranged on the outer side of the transverse guide wheel, a groove is opened in the middle position of the table, a vertical wheel frame is fixedly connected to the top side of the groove, and two guide wheels are rotatably connected to the end of the vertical wheel frame, the outer side surface of the chain is fixedly connected to a clamping frame, a clamping block is slidably connected to the outer side of the clamping frame, a rubber strip is fixedly connected to the side of the clamping block, a vibrating arc plate is fixedly connected to the side of the side sealing plate, and a cam is arranged below the vibrating arc plate.

[0009] According to the above technical solution, the overall shape of the vertical wheel frame is V-shaped, a spring is arranged between the clamping block and the clamping frame, and the two ends of the spring are fixedly connected to the clamping block and the clamping frame respectively, and a rubber strip is also fixedly connected to the end of the clamping block near the clamping block. The cam is fixedly connected to the axis of the guide wheel located above. When the axis of the transverse guide wheel is driven by an external motor to rotate, the rotation of the transverse guide wheel drives the connected chain to rotate together, so that the chain drives the connected clamping frame to move, and the edge of the bag is placed between the rubber strip of the clamping frame and the rubber strip of the clamping block. The return spring pushes the clamping block to clamp the edge of the bag through the rubber strip. When the clamping block clamping the bag moves to the groove, the clamping blocks on both sides move away from each other to open the bag mouth, making it convenient for the material to fall into the bag and avoiding the waste of the material falling to the outside of the bag. At the same time, the guide wheel used for the restraining chain allows the restraining chain to be guided into the groove through the rotation of the guide wheel. During the rotation of the guide wheel, the cam connected to the guide wheel rotates and contacts the vibrating arc piece, so that the elastic vibrating arc piece is compressed and reset to vibrate, and the vibration of the vibrating arc piece drives the connected side sealing plate to vibrate.

[0012] According to the above technical scheme, one end of the air cylinder rod away from the slot rod seat is fixedly connected to the inclined slot block, and the heat sealing strip passes through one side of the pressure plate and out of the other side. When the linkage rod connected to the vertical connecting rod moves downward, the linkage rod moves and drives the connected linkage plate to move downward to push the pressure rod, so that the pressure rod slides along the inclined slot block. After being squeezed by the pressure rod, the inclined slot block pushes the slot block connecting rod to slide along the connection part of the slot rod seat, and allows the pressure plates connected to the slot block connecting rods on both sides to approach each other, and the bag mouth clamped by the clamping block is clamped by approaching each other, and the bag is heated and sealed by the contacting heat sealing strips, thereby realizing automatic sealing of the loaded bag. At the same time, the movement of the inclined slot block will squeeze the air in the air cylinder rod, so that the air in the air cylinder rod enters the connected inner cavity plate, and the inner cavity plate is sprayed out from the side of the pressure plate, and the attached materials at the bag mouth are blown away by the sprayed air.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are:

At the same time, when the cylinder contracts upward, the chute rod moves upward to drive the connected hanging plate to lift upward, so that the weighing plate on the hanging plate contacts the bottom of the bag. As the weighing plate rises, the weight of the material loaded in the bag is weighed through the bottom gravity sensor, so that when the weight difference is large, the cylinder is controlled to extend to release a small amount of material at the material discharge chute for replenishment, thereby improving the accuracy of the bag loading weight.

[0015] The present invention prevents materials from falling outside the bag and causing waste by arranging a transverse guide wheel, a chain, a groove, a vertical wheel frame, a guide wheel, a clamping frame, a clamping block, a rubber strip, a vibrating arc sheet, and a cam. At the same time, the guide wheel for restraining the chain allows the restraining chain to be guided into the groove through the rotation of the guide wheel. During the rotation of the guide wheel, the cam connected to the guide wheel rotates to contact the vibrating arc sheet, so that the elastic vibrating arc sheet is pressed and reset to vibrate. The vibration of the vibrating arc sheet drives the connected side sealing plate to vibrate, so as to prevent the attachment of materials in the side sealing plate and on the connected structure to affect the loading weight accuracy, thereby avoiding material waste.

[0016] The present invention is provided with a linkage rod, a linkage plate, a pressure rod, an inclined slot block, a slot block connecting rod, a slot rod seat, a pressure plate, a cylinder rod, an inner cavity plate, and a heat sealing strip. The bag is heated and sealed by the contacting heat sealing strips, thereby realizing automatic sealing of the loaded bag.

[0033] Working principle: In the initial state, the material in the hopper 3 enters between the two material control side plates 53 through the material discharge chute 51, so that the material fills the material control side plates 53. When the bag is located directly below the sealing plate 55, the cylinder 4 contracts upward, and the cylinder 4 pushes the slide rod 57 upward through the fixed rod plate, so that the slide rod 57 pushes the deflection slot plate 56 to deflect around the node where the sealing plate 55 and the side sealing plate 52 are connected. After the deflection slot plate 56 is deflected, the sealing plates 55 are moved away from each other, and the material limiting plate 54 connected to the deflection slot plate 56 slides against the side of the top material discharge chute 51 to seal the top of the material discharge chute 51. , so that the material in the material control side plate 53 falls into the bag through the bottom of the sealing plate 55, preventing the material in the hopper 3 from falling continuously, ensuring the uniformity of the bag loading weight. At the same time, when the cylinder 4 contracts upward, the slide rod 57 moves upward to drive the connected hanging plate 59 to lift upward, so that the weighing plate 510 on the hanging plate 59 contacts the bottom of the bag. As the weighing plate 510 rises, the weight of the material loaded in the bag is weighed through the bottom gravity sensor 511, so that when the weight difference is large, the cylinder 4 is controlled to extend, so that a small amount of material is released from the lower chute 51 to supplement, thereby improving the accuracy of the bag loading weight;

[0034] When the axis of the transverse guide wheel 61 is driven by an external motor to rotate, the rotation of the transverse guide wheel 61 drives the connected chain 62 to rotate together, so that the chain 62 drives the connected clamping frame 66 to move, and the edge of the bag is placed between the rubber strip 68 of the clamping frame 66 and the rubber strip 68 of the clamping block 67. The reset spring pushes the clamping block 67 to clamp the edge of the bag through the rubber strip 68. When the clamping block 67 clamping the bag moves to the groove 63, the clamping blocks 67 on both sides move away from each other to open the bag mouth, so that the material can fall into the bag conveniently. To prevent the material from falling outside the bag and causing waste, at the same time, the guide wheel 65 for the binding chain 62 allows the binding chain 62 to be guided into the groove 63 through the rotation of the guide wheel 65. During the rotation of the guide wheel 65, the cam 610 connected to the guide wheel 65 rotates to contact the vibrating arc piece 69, so that the elastic vibrating arc piece 69 is pressed and reset to vibrate. The vibration of the vibrating arc piece 69 drives the connected side sealing plate 52 to vibrate, preventing the attachment of materials in the side sealing plate 52 and the connected structure from affecting the loading weight accuracy, thereby avoiding material waste;
