Description

Technical Field

[0001] This utility model relates to the field of plastic granule packaging machine technology, and in particular to a receiving device for a plastic granule packaging machine. Background Technology

[0002] Plastic granules are small granular substances made from natural resins or recycled plastics through processes such as melting, extrusion, and pelletizing. Plastic granule packaging machines are automated equipment specifically designed for the automatic metering, filling, sealing, and packaging of plastic granules. The receiving device of a plastic granule packaging machine is a key component in the plastic granule packaging production line, used to receive, temporarily store, and organize finished plastic granule bags that have completed the packaging process. It is connected to the discharge end of the packaging machine and, through mechanical structures or automated systems, orderly collects and transports the packaged plastic granules to subsequent stages to achieve continuity and efficiency in the packaging process.

[0003] Existing plastic granule packaging machines are inconvenient for quantitative collection of plastic granules, requiring operators to control the opening and closing of the feeding device based on the weighing device in order to achieve quantitative collection.

[0004] Therefore, a receiving device for plastic pellet packaging machines is needed to solve the above problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned receiving device for a plastic granule packaging machine, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a receiving device for a plastic granule packaging machine, which solves the problem that "existing plastic granule packaging machines are inconvenient to quantitatively receive plastic granules, which requires operators to control the opening and closing of the feeding device according to the weighing device in order to achieve quantitative receiving".

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a receiving device for a plastic granule packaging machine, comprising:

[0009] A feeding hopper, with a support frame below the feeding hopper and a base plate below the support frame;

[0010] The metering unit is located below the hopper and includes an air pipe, a first sealing rod, a second sealing rod, a slip ring, and an arc plate. The first sealing rod moves downward to push the gas inside the air pipe, and the second sealing rod moves upward to squeeze the outer wall of the arc plate through the slip ring. Multiple sets of arc plates close and stop feeding, so as to achieve the effect of metered collection of plastic granules.

[0011] The receiving unit is located inside the metering unit. The receiving unit includes a receiving frame and a positioning column, which are used to realize alternating receiving to improve the receiving efficiency of plastic granules. The feeding hopper is connected to the metering unit. The metering unit quantitatively receives plastic granules. Under the restriction of the receiving unit, alternating receiving can be realized to improve the receiving efficiency of plastic granules.

[0012] As a preferred embodiment of the material receiving device for a plastic granule packaging machine according to the present invention, the device includes a metering unit comprising an L-shaped plate fixedly installed on the top surface of a base plate, an air pipe fixedly installed inside the L-shaped plate, a retaining ring fixedly installed on the inner wall of the air pipe, a spring fixedly installed on the top surface of the retaining ring, a first sealing rod fixedly installed at the end of the spring away from the retaining ring, a second sealing rod slidably disposed inside the air pipe, a connecting plate fixedly installed at the end of the second sealing rod, and a slip ring fixedly installed at the end of the connecting plate.

[0013] As a preferred embodiment of the material receiving device for a plastic granule packaging machine described in this utility model, a connecting ring is fixedly installed at the end of the bracket, and an arc plate is hinged to the bottom of the connecting ring.

[0014] As a preferred embodiment of the material receiving device for a plastic granule packaging machine described in this utility model, the first sealing rod and the second sealing rod slide in a sealed manner with the inside of the air pipe, and the outer wall of the slip ring slides in a sliding manner with the outer wall of the arc plate. When the first sealing rod is pressed and slides into the air pipe, the second sealing rod slides outward from the air pipe, pushing the slip ring and causing the slip ring to squeeze the outer wall of the arc plate, closing the arc plate. At this time, no more material is fed, thus achieving a quantitative material receiving effect.

[0015] As a preferred embodiment of the material receiving device for a plastic granule packaging machine described in this utility model, there are eight arc plates distributed in a circular pattern. Under the constraint of the hinged arc plates, when the slip ring no longer presses against its outer wall, the arc plates open under the pushing force of the plastic granules and the gravity of the arc plates, so that the material receiving work can be carried out.

[0016] As a preferred embodiment of the material receiving device for a plastic granule packaging machine described in this utility model, the material receiving unit includes a sleeve block slidably disposed on the outer wall of the support, a sliding frame fixedly installed on the outer wall of the sleeve block, a groove being provided on the inner wall of the sliding frame, and an elastic sheet being fixedly installed inside the groove.

[0017] As a preferred embodiment of the material receiving device for a plastic granule packaging machine described in this utility model, a material receiving frame is slidably arranged inside the sliding frame, and a positioning column is fixedly installed on the top surface of the material receiving frame.

[0018] As a preferred embodiment of the receiving device for a plastic granule packaging machine described in this utility model, the elastic sheet is made of elastic material and is arranged in an arc shape. When the receiving frame is pulled, the elastic sheet is pressed and deformed into the groove. The elastic sheet no longer restricts the receiving frame, so the receiving frame can be pulled to place the empty bag under the connecting ring and the arc plate.

[0019] The beneficial effects of this utility model are as follows: During quantitative material collection, the material collection unit presses down on the first sealing rod due to gravity, causing it to slide into the air pipe and compress the spring. With the help of the first and second sealing rods that slide together, the first sealing rod pushes the gas in the air pipe, causing the second sealing rod to slide outward, which drives the connecting plate and the slip ring to move upward. The slip ring squeezes the arc plate to close it, and the hopper stops discharging material. After the empty bag is replaced, the material collection unit no longer applies pressure, the spring pushes the first sealing rod to reset, the second sealing rod slides inward, the arc plate opens and continues to discharge material, thus realizing quantitative bagging of plastic granules.

[0020] When collecting materials, simply place the bag onto the positioning post. Once the bag is full, place the empty bag on the side, press the elastic sheet, and pull the collecting frame to position the empty bag at the unloading position. After removing the full bag, the collecting unit resets, and the arc plate opens to unload the material, achieving alternating collecting and improving efficiency. Attached Figure Description

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a receiving device for a plastic granule packaging machine, comprising:

[0035] A feeding hopper 100 is provided below the feeding hopper 100, and a base plate 102 is provided below the support 101.

[0036] The metering unit 200 is located below the hopper 100. The metering unit 200 includes an air pipe 202, a first sealing rod 205, a second sealing rod 206, a slip ring 208, and an arc plate 210. The first sealing rod 205 pushes the gas inside the air pipe 202 downward, and the second sealing rod 206 moves upward. The slip ring 208 squeezes the outer wall of the arc plate 210, and multiple sets of arc plates 210 close to stop feeding, so as to achieve the effect of metered collection of plastic granules.

[0037] The receiving unit 300 is located inside the quantitative unit 200. The receiving unit 300 includes a receiving frame 305 and a positioning post 306, which are used to achieve alternating receiving to improve the receiving efficiency of plastic granules.

[0038] In use, the feeding hopper 100 is connected to the metering unit 200. The metering unit 200 quantitatively collects plastic granules. Under the constraint of the collecting unit 300, alternating collection can be achieved to improve the collection efficiency of plastic granules.

[0039] Example 2

[0040] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as follows:

[0041] The quantitative unit 200 includes an L-shaped plate 201 fixedly installed on the top surface of the base plate 102. An air tube 202 is fixedly installed inside the L-shaped plate 201. A retaining ring 203 is fixedly installed on the inner wall of the air tube 202. A spring 204 is fixedly installed on the top surface of the retaining ring 203. A first sealing rod 205 is fixedly installed at the end of the spring 204 away from the retaining ring 203. A second sealing rod 206 is slidably arranged inside the air tube 202. A connecting plate 207 is fixedly installed at the end of the second sealing rod 206. A slip ring 208 is fixedly installed at the end of the connecting plate 207. A connecting ring 209 is fixedly installed at the end of the bracket 101. An arc plate 210 is hinged to the bottom of the connecting ring 209.

[0042] The first sealing rod 205 and the second sealing rod 206 are sealed and slide inside the air pipe 202. The outer wall of the slip ring 208 is slidably set with the outer wall of the arc plate 210. When the first sealing rod 205 is pressed and slides into the air pipe 202, the second sealing rod 206 slides out of the air pipe 202 and pushes the slip ring 208, causing the slip ring 208 to squeeze the outer wall of the arc plate 210 and close the arc plate 210. At this time, no more material is fed, and the quantitative material collection effect can be achieved.

[0043] There are eight arc plates 210, which are distributed in a circle around the center of the ring 209. Under the constraint of the hinged arc plates 210, when the slip ring 208 no longer presses against its outer wall, the arc plates 210 are opened by the pushing of the plastic particles and the gravity of the arc plates 210, so that the material collection work can be carried out.

[0044] During use, when collecting plastic granules, a quantitative collection is required. When the collecting unit 300 is subjected to gravity, it presses against the first sealing rod 205, causing the first sealing rod 205 to slide into the air pipe 202. This, in conjunction with the retaining ring 203, compresses the spring 204. Due to the sealing and sliding of the first sealing rod 205 and the second sealing rod 206 within the air pipe 202, the first sealing rod 205 pushes the gas inside the air pipe 202, while the second sealing rod 206 slides outward from the air pipe 202. This causes the connecting plate 207 and the slip ring 208 to move upward. The slip ring 208 slides and presses against the outer wall of the arc plate 210, causing the arc plate 210 to... The hinge point of the connecting ring 209 is the center of rotation, until the slip ring 208 closes the arc plate 210. At this time, the hopper 100 no longer feeds material into the connecting ring 209. The empty bag is then fitted onto the receiving unit 300, and the full bag is removed. At this time, the receiving unit 300 no longer presses against the first sealing rod 205. Under the elastic action of the spring 204, the first sealing rod 205 is pushed upward, and the second sealing rod 206 slides into the air pipe 202. At this time, the slip ring 208 no longer slides and squeezes against the outer wall of the arc plate 210, and the connecting ring 209 can feed material into the empty bag. This structure can open and close the arc plate 210 to add plastic granules to the bag in a quantitative manner.

[0045] Example 3

[0046] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below:

[0047] The receiving unit 300 includes a sleeve block 301 that is slidably disposed on the outer wall of the bracket 101. A sliding frame 302 is fixedly installed on the outer wall of the sleeve block 301. A groove 303 is provided on the inner wall of the sliding frame 302. An elastic sheet 304 is fixedly installed inside the groove 303. A receiving frame 305 is slidably disposed on the inner side of the sliding frame 302. A positioning post 306 is fixedly installed on the top surface of the receiving frame 305.

[0048] Among them, the elastic sheet 304 is made of elastic material and is set with an arc surface. When the receiving frame 305 is pulled, the elastic sheet 304 is pressed and deformed into the groove 303. The elastic sheet 304 no longer restricts the receiving frame 305, so the receiving frame 305 can be pulled and the empty bag is placed under the connecting ring 209 and the arc plate 210.

[0049] In use, when collecting plastic granules, the bag is placed on the outer wall of the positioning post 306 to start the collection work. When the bag is full, the empty bag is placed on the side of the full bag, the elastic sheet 304 is pressed, and it deforms into the groove 303, pulling the collection frame 305 and placing the empty bag under the connecting ring 209 and the discharge hopper 100. The full bag is then removed from the inside of the collection frame 305. At this time, the collection unit 300 is not under gravity. Under the elastic action of the spring 204, the first sealing rod 205 is pushed upward. At this time, the slip ring 208 no longer squeezes the arc plate 210, and the discharge work can be carried out. This structure can realize alternating collection to improve collection efficiency.

[0050] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0051] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
