For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0035] In one embodiment of the present invention, according to Figure 1-4As shown, a quantitative packaging device for plastic particles includes a frame 100 and a quantitative device 200, a film passing device 300 and a packaging device arranged on the frame 100; the quantitative device 200 includes a quantitative component 210 and a feed box 220 arranged on the quantitative component 210; the quantitative component 210 can weigh the weight of the feed box 220; the feed box 220 is also provided with an interception component 230, and the interception component 230 is used to intercept the plastic particles entering the feed box 220 from the first feed hopper 240; a second feed hopper 250 is provided below the feed box 220, and a feed pipe 260 is provided below the second feed hopper 250;

[0036] The film passing device 300 includes a film passing frame 310; a film passing shaft 320 is provided on the film passing frame 310, and the packaging device includes a longitudinal packaging component 410, a transverse packaging component 420 and a driving device 600 for driving the longitudinal packaging component 410 and the transverse packaging component 420; the transverse packaging component 420 is arranged below the longitudinal packaging component 410, and the roll film 330 on the film passing frame 310 passes around the film passing shaft 320, and then passes through the longitudinal packaging component 410 and the transverse packaging component 420 to be packaged into bags.

[0037] Specifically, plastic particles enter the feed box 220 from the first feed hopper 240 and are weighed by the quantitative component 210. When a certain weight is reached, the interception component 230 is used to intercept the plastic particles entering the feed box 220 from the first feed hopper 240. The plastic particles pass from the feed box 220 through the second feed hopper 250 and enter the feed pipe 260. After the roll film 330 on the film rack 310 passes around the film shaft 320, the plastic particles flowing into the bag are packaged into bags through the longitudinal packaging component 410 and the transverse packaging component 420.

[0038] Furthermore, by setting the quantitative component 210 for weighing, the plastic particles can be packaged quantitatively, ensuring the weight of each bag of plastic packaging, without the need for subsequent manual weighing, reducing the workload and labor costs. By setting the interception component 230, when the weight of the feed box 220 reaches the set value, the first feed hopper 240 is blocked from entering the feed box 220, ensuring that the weight of the plastic particles after packaging is consistent with that in the feed box 220, and the weight is more accurate.

[0039] In another embodiment of the present invention, according to Figure 1 and 2 As shown, the first feed hopper 240 is disposed above the feed box 220, and the end of the first feed hopper 240 is U-shaped. The interception assembly 230 includes a cylinder 231 and an interception plate 232 connected to the cylinder 231; the cylinder 231 is disposed on the inner wall of the feed box 220, and the cylinder 231 can extend and retract to drive the interception plate 232 to rise and cover the end of the first feed hopper 240, intercepting the plastic particles from the first feed hopper 240 entering the feed box 220.

[0040] Specifically, when the weight of the plastic particles in the feed box 220 reaches a preset value, the cylinder 231 will drive the interception plate 232 to move upward to block the end of the feed hopper, so that the plastic particles in the first feed hopper 240 no longer enter the feed box 220. The end of the first feed hopper 240 is U-shaped, and the interception plate 232 is a flat plate, which can just cover the end of the first feed hopper 240 without leaving a gap for the plastic particles to flow out.

[0041] In another embodiment of the present invention, according to Figure 1 and 2 As shown, the feed box 220 has an opening 221 at the bottom, and a second feed hopper 250 is provided below the opening 221. Plastic particles flowing out of the opening 221 flow into the second feed hopper 250. The bottom of the feed box 220 has a slope, and the opening 221 is located at the lowest point of the bottom of the feed box 220.

[0042] Specifically, the bottom of the feed box 220 has a slope, and the opening 221 is located at the lowest point of the bottom of the feed box 220, so that all the plastic particles in the feed box 220 can flow into the second feed hopper 250, thereby ensuring that the weight of the plastic particles after packaging is consistent with that in the feed box 220, and the weight is more accurate.

[0043] In another embodiment of the present invention, according to Figure 2 As shown, the quantitative component 210 includes a weighing plate 211 and a liquid crystal screen 212 disposed on the weighing plate 211 , and the liquid crystal screen 212 is used to display the weight weighed by the weighing plate 211 .

[0044] Specifically, a feed box 220 is provided on the weighing plate 211, and the weight of the feed box 220 can be subtracted in advance. At this time, the weight on the weighing plate 211 is the weight of the plastic particles. When the preset value is reached, the feeding stops. The LCD screen 212 can display the dynamic weight and the preset weight, which can be displayed intuitively and is more convenient for the operator.

[0045] In another embodiment of the present invention, according to Figure 1 and 2 As shown, the feed pipe 260 is provided with a former 270 matched therewith, and the roll film 330 on the film frame 310 passes around the film shaft 320, passes through the former 270, and is then packaged into bags through the longitudinal packaging component 410 and the transverse packaging component 420.

[0046] Specifically, the rolled film 330 on the film passing frame 310 passes through the former 270 , and under the action of the former 270 , both sides of the rolled film 330 are bent inward and wrap around the feed pipe 260 and the former 270 .

[0047] In another embodiment of the present invention, according to Figure 3 and4 As shown, the longitudinal packaging assembly 410 includes two first transmission rods 411, two second transmission rods 412 and two longitudinal sealing plates 413; the two second transmission rods 412 are movably mounted on the frame 100, the two longitudinal sealing plates 413 are symmetrically mounted on the two second transmission rods 412, and a longitudinal sealing position is provided between the two longitudinal sealing plates 413; the two second transmission rods 412 are respectively connected to the driving device 600 through the two first transmission rods 411. The transverse packaging assembly 420 includes two third transmission rods 421, two fourth transmission rods 422 and two transverse sealing plates 423; the two fourth transmission rods 422 are movably mounted on the frame 100, the two transverse sealing plates 423 are symmetrically mounted on the two fourth transmission rods 422, and a transverse sealing position is provided between the two transverse sealing plates 423; the two fourth transmission rods 422 are respectively connected to the driving device 600 through the two third transmission rods 421.

[0048] Specifically, the longitudinal packaging assembly 410 and the transverse packaging assembly 420 are on one side of the former 270. When the roll film 330 passes through the longitudinal packaging assembly 410, the longitudinal packaging assembly 410 is driven by the driving device 600, and the two longitudinal sealing plates 413 seal the sides of the roll film 330. When the roll film 330 passes through the longitudinal packaging assembly 410, the transverse packaging assembly 420 is driven by the driving device 600, and the two transverse sealing plates 423 seal the front side of the roll film 330 to form a roll film bag. The plastic particles fall into the roll film bag with front and side seals through the feed pipe 260 and the former 270. When the plastic particles in the feed box 220 have flowed out, the two horizontal sealing plates 423 are opened, and the roll film bag 330 containing the plastic particles continues to move downward due to gravity. When the two horizontal sealing plates 423 are closed, the back of the roll film bag containing the plastic particles is sealed to form a closed package. This process is repeated to achieve the purpose of packaging the plastic particles.

[0049] Furthermore, electric heating wires (not shown) are provided inside the transverse sealing plate 423 and the longitudinal sealing plate 413 to heat the plates and achieve plate heat sealing.

[0050] Furthermore, the driving device 600 drives the longitudinal packaging component 410 and the transverse packaging component 420 to move, which is an existing mature technology and is not the focus of protection in the present utility model, and will not be described in detail.

[0051] In another embodiment of the utility model, Figure 1-4 As shown, a film transport device 500 is also provided on the frame 100 . The film transport device 500 is disposed between the longitudinal packaging component 410 and the transverse packaging component 420 . The film transport device 500 is used to assist in transporting the roll film 330 .

[0052] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.

[0053] The above content is a further detailed description of the utility model in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, its architecture can be flexible and can derive a series of products. Just making a few simple deductions or substitutions should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
