Description

Technical Field

[0001] The invention belongs to the technical field of plasticine packaging, and in particular relates to a plasticine packaging machine. Background Art

[0002] Plasticine is the predecessor of colored clay. It has always been the favorite toy of children. At first, plasticine was only grayish white, but in the following years, plasticine has a variety of colors and fragrances, including luminous, gold, silver, shampoo, shaving water, etc.

[0003] Existing plasticine often uses ziplock bags to quantitatively package plasticine of different colors. The packaging method is often to manually fill a quantitative amount of plasticine into the ziplock bag, then manually squeeze and flatten the ziplock bag, and then squeeze and seal the ziplock bag. After closing, the ziplock bag is flattened again. Although the traditional packaging method can well solve the problem of plasticine packaging, it is relatively cumbersome to operate, the packaging efficiency is low, and the precision of manual packaging is also low; in addition, the manual packaging process often uses hand pressing to flatten, which results in the flattened surface being not neat.

[0032] See Figure 1-9 , a plasticine packaging machine, comprising

[0033] At least one filling component 200, the filling component 200 includes a feeding component 210, a quantitative component 220 and a pushing component 230, the plasticine to be filled is located in the feeding component 210, the quantitative component 220 includes a fixed volume container 221, the container 221 is hollow to form a container, the feeding component 210 can feed the plasticine to be filled into the container; the feeding component 210 includes a servo motor 211, a transmission component 212, a feeding component 213, an extruder 214 and a barrel 215, the barrel 215 is fixedly arranged above the feeding component 213, and the feeding component 213 is located above the entrance of the extruder 214, and the feeding assembly 213 includes two symmetrically arranged feeding rods. The servo motor 211 drives the extruder to operate through the feeding assembly 213, and also drives the two feeding rods to rotate towards each other to add the plasticine in the barrel 215 into the extruder 214, and the plasticine is squeezed out from the extruder outlet 2141 through the action of the extruder 214; preferably, the extruder 214 is a screw extruder, so the number of rotations of the screw of the extruder can be controlled by controlling the number of rotations of the servo motor 211, so the extrusion amount of the plasticine can be controlled. It is further preferred that the push assembly 230 includes a push rod 2311, a push rod driving mechanism 231, a vertical reciprocating push mechanism 235 and a horizontal reciprocating push mechanism 233, one end of the push rod 2311 is located in the accommodating cavity of the accommodating cylinder 221, and the other end is fixedly arranged at the output end of the push rod driving mechanism 231, the accommodating cylinder 221, the push rod 2311 and the push rod driving mechanism 231 are fixedly arranged at the output end of the horizontal reciprocating push mechanism 233, and the horizontal reciprocating push mechanism 233 is fixedly arranged at the output end 2351 of the vertical reciprocating push mechanism 235; the accommodating cylinder 221, the push rod 2311 and The push rod driving mechanism 231 switches from the front of the filling station to the front of the bagging station with the help of the movement of the output end 2351 of the vertical reciprocating pushing mechanism; the accommodating cylinder 221, the push rod 2311 and the push rod driving mechanism 231 enter the filling station and the bagging station with the help of the movement of the output end of the horizontal reciprocating pushing mechanism 233; in this embodiment, the horizontal reciprocating pushing mechanism 233 preferably includes a servo motor and a screw nut pair structure, so that by controlling the speed and number of rotations of the servo motor, the nut moving speed and moving distance of the screw nut pair can be accurately controlled.

[0034] When the accommodating cylinder 221 is located at the filling station, the horizontal reciprocating pushing mechanism 233 drives the accommodating cylinder 221 to move toward the extruder outlet 2141, so that the accommodating cylinder 221 is inserted into the outlet 2141 of the extruder away from the opening on the side of the push rod. Then, starting the feeding assembly 210 can squeeze the plasticine into the accommodating chamber of the accommodating cylinder 221 through the extruder. Since the volume of the accommodating chamber is fixed and the number of revolutions of the servo motor can be used to accurately quantify the plasticine supplied into the accommodating cylinder 221.

[0035] At least one bag opening component 300, the bag opening component 300 can open the bag mouth of the ziplock bag 600 located in the bag opening component 300 to a set opening; after the bag opening component 300 opens the bag mouth of the ziplock bag, the pushing component 230 can push the plasticine to be filled in the accommodating chamber of the accommodating cylinder 221 into the ziplock bag through the bag mouth; specifically, the bag opening component 300 includes a ziplock bag temporary storage area 310 and a bag opening mechanism, the bag opening mechanism includes an upper suction cup component 321, a lower suction cup component 322, a suction cup vertical reciprocating motion mechanism 324 and a suction cup horizontal reciprocating motion mechanism 326, the suction cup vertical reciprocating motion mechanism 324 is fixedly arranged at the output end of the suction cup horizontal reciprocating motion mechanism 326, the lower suction cup component 322 is fixedly arranged at the output end of the suction cup vertical reciprocating motion mechanism 324, the upper suction cup component 321 is fixedly arranged on one side of the ziplock bag temporary storage area 310 through a fixing bracket 325, and the upper suction cup component 321 and the accommodating cylinder 221 are fixedly arranged on the output end of the suction cup vertical reciprocating motion mechanism 326 The lower suction cup assembly 322 is located directly below the ziplock bag temporary storage area 310, and the ziplock bag temporary storage area 310 has a bag outlet channel 311 at one end of the ziplock bag temporary storage area 310 facing the lower suction cup assembly 322. The lower suction cup assembly 322 switches between the lower part of the ziplock bag temporary storage area 310 and the lower part of the upper suction cup assembly 321 by means of the movement of the output end of the suction cup horizontal reciprocating motion mechanism 326. 0, the suction cup vertical reciprocating motion mechanism 324 is moved upward to the bag outlet channel 311 to adsorb the ziplock bag in the ziplock bag temporary storage area 30 and then move downward to pull the ziplock bag out through the bag outlet channel 311; when the lower suction cup assembly 322 is located below the upper suction cup assembly 321, the suction cup vertical reciprocating motion mechanism 324 is moved upward to make the upper suction cup assembly 321 adsorb the side of the ziplock bag away from the lower suction cup assembly 322 and then move downward to open the bag mouth of the ziplock bag.

[0036] It should be noted that the ziplock bag temporary storage area 310 is provided with a limiting component at the bag outlet channel 311, and the limiting component limits the ziplock bags in the ziplock bag temporary storage area 310, thereby preventing the ziplock bags in the ziplock bag temporary storage area 310 from freely falling through the bag outlet channel 311; after the lower suction cup component 322 absorbs the part of the ziplock bag exposed outward from the bag outlet channel 311 through the bag outlet channel 311, the limiting resistance of the limiting component is overcome under the drive of the suction cup vertical reciprocating motion mechanism 324, and the ziplock bag can be pulled out through the bag outlet channel 311. In addition, it should be noted that the upper suction cup component 321 and the lower suction cup component 322 are both composed of suction cups and vacuum generators, and their structures and working principles are the same as those of the prior art, which will not be repeated here.

[0037] When the bag opening component 300 is located at the bagging station, after the bag opening component 300 opens the bag mouth of the ziplock bag 600 and when the accommodating tube 221, the push rod 2311 and the push rod driving mechanism 231 are located at the bagging station, the horizontal reciprocating pushing mechanism 233 drives the accommodating tube 221, the push rod 2311 and the push rod driving mechanism 231 to move toward the ziplock bag 600, so that the opening on the side of the accommodating tube 221 away from the push rod 2311 enters the ziplock bag from the bag mouth, and the output end of the push rod driving mechanism 231 drives the push rod 2311 to move further into the accommodating cavity of the accommodating tube 221, preferably, the push rod 2311 is matched with the clearance of the accommodating cavity, so that in the process of the push rod 2311 moving into the accommodating cavity, the plasticine in the accommodating cavity is forced to be discharged from the opening on the side of the accommodating cavity away from the push rod 2311 into the ziplock bag, thereby realizing the filling of the plasticine into the ziplock bag.

[0038] Furthermore, considering that the plasticine has a certain viscosity, if the feeding assembly is directly separated after replenishing the accommodating cylinder 221, part of the plasticine will be drawn due to the viscosity of the plasticine. Therefore, it is necessary to cut off the plasticine at the outlet of the extruder and the accommodating cylinder 221 in time. For this reason, the present embodiment is provided with a cutter 2142 at the outlet 2141 of the extruder. The cutter 2142 is driven by a cylinder 2143 and a connecting rod 2144. When the feeding is completed, the cylinder 2143 drives the connecting rod 2144 to swing, thereby driving the cutter 2142 to move downward to cut off the plasticine at the outlet 2141 of the extruder.

[0039] The sealing component 400 includes a flattening component 420 and a mouth-pressing component 430. The flattening component 420 has a wedge-shaped flattening channel, and the mouth-pressing component 430 has a mouth-pressing channel b. The mouth-pressing channel b is located in the flattening channel to divide the flattening channel into a first flattening channel a and a second flattening channel c. The ziplock bag filled with plasticine enters the first flattening channel a from the entrance of the flattening component 420, is squeezed by the first flattening channel a, and is flattened for the first time. After passing through the mouth-pressing channel b, the mouth of the ziplock bag is closed by the mouth-pressing component and then enters the second flattening channel c. After being squeezed by the second flattening channel a, the ziplock bag is flattened for the second time and then moves out from the outlet of the second flattening channel c, thereby achieving flattening and sealing of the ziplock bag.

[0040] Specifically, the flattening assembly 420 includes a plurality of groups of upper rolling wheel assemblies 421 arranged side by side, a plurality of groups of lower rolling wheel assemblies 422 arranged side by side, an upper conveyor belt 470 surrounding the outer portion of the upper rolling wheel assemblies 421, and a lower conveyor belt 480 surrounding the outer portion of the lower rolling wheel assemblies 422. The upper conveyor belt 470 and the lower conveyor belt 480 enclose a first flattening channel a and a second flattening channel c. The spacing between the upper rolling wheel assemblies 421 and the lower rolling wheel assemblies 422 is determined by the inlet of the flattening assembly. The mouth is gradually reduced like its outlet; the pressing assembly 430 includes two symmetrically arranged first pressing rollers 431 and second pressing rollers 432, and the minimum gap between the roller surfaces of the first pressing roller 431 and the second pressing roller 432 is set to a suitable spacing. When the bag mouth of the ziplock bag passes between the first pressing roller 431 and the second pressing roller 432, the self-sealing mouth of the ziplock bag can be squeezed and closed by the squeezing of the first pressing roller 431 and the second pressing roller 432.

[0041] Furthermore, the sealing assembly 400 also includes a sealing drive mechanism, which includes a driving motor 411 and a first transmission assembly 410, a second transmission assembly 450 and a third transmission assembly 460. The first transmission assembly 410 transmits the power of the driving motor 411 to the first pressure roller 431, the second transmission assembly 450 transmits the power of the first pressure roller 431 to the second pressure roller 432, and the third transmission assembly 460 transmits the power of the second pressure roller 432 to the upper pressure roller 431. The first transmission assembly 410 includes a first driving wheel 412, a first driven wheel 413 and a transmission belt 414. The output end of the driving motor 411 is connected to a reducer. The first driving wheel 412 is fixedly arranged at the output end of the reducer. The first driven wheel 413 is coaxial with the first pressure roller 431 and is fixedly connected. The first driving wheel 412 is transmitted to the first driven wheel 413 through the transmission belt 414, so that the driving motor 411 drives the first pressure roller 431 to rotate. The second transmission assembly 450 includes a second driving tooth 451 and a second driven tooth 452. The second driving tooth 451 and the second driven tooth 452 are of the same size. The second driving tooth 451 and the second driven tooth 452 are kneaded together. The second driving tooth 451 is coaxial with and fixedly connected to the other end of the first pressure roller 431. The second driven tooth 452 is coaxial with and fixedly connected to one end of the second pressure roller 432, thereby realizing synchronous and synchronous rotation of the first pressure roller 431 and the second pressure roller 432. The three-transmission assembly 460 includes a third driving wheel 461, a third driven wheel 462 and a third transmission belt 463. The third driving wheel 461 is fixed to one end of the second pressure roller 432 away from the second driven tooth 452, and the third driven wheel 462 is fixed to a driving wheel of the upper rolling wheel group 421, so as to transmit the power of the second pressure roller 432 to the upper rolling wheel group 421 to drive it to operate; thus, the operation of the entire sealing assembly can be realized by a driving motor 411.

[0042] In order to better achieve the simultaneous sealing of the ziplock bag during pressing, the first pressing roller 431 and the second pressing roller 432 are preferably fixed on the two oppositely arranged upper rollers 421a and lower rollers 422a of the upper rolling wheel group 421 and the lower rolling wheel group 422, respectively.

[0043] Since the outer diameters of the first pressure roller 431 and the second pressure roller 432 are equal and larger than the outer diameters of the upper roller 421a and the lower roller 422a of the lower rolling wheel group 422 and the upper rolling wheel group 421, if the rotation speeds of the upper roller 421a and the lower roller 422a are equal to the rotation speeds of the first pressure roller 431 and the second pressure roller 432 during actual operation, the linear speeds of the roller surfaces of the first pressure roller 431 and the second pressure roller 432 will inevitably be greater than the linear speeds of the upper conveyor belt 470 and the lower conveyor belt 480, which will cause the first pressure roller 431 and the second pressure roller 432 to roll themselves If the speed of self-sealing of the sealed bag is faster than the conveying speed of the flattening component, the self-sealing bag will be torn or twisted. In order to solve this problem, in this embodiment, the transmission ratio of the second transmission component 450 is preferably one, and the transmission ratio of the third transmission component 460 is less than one. This is equivalent to accelerating the rotation speed of the lower rolling wheel group 422 and the upper rolling wheel group 421 through the third transmission component 460, so that the linear speed of the roller surface of the first pressure roller 431 and the second pressure roller 432 is equal to the linear speed of the upper conveyor belt 470 and the lower conveyor belt 480. This can solve the problem well and seal the bag simultaneously during flattening.

[0044] Further preferably, in order to allow the filled ziplock bags to directly enter the flattening assembly for flattening and subsequent sealing operations, the flattening assembly 420 in this embodiment preferably extends an extension section 4221 toward its inlet side, and the bag opening assembly 300, the dosing assembly 220 and the pushing assembly 230 are located on the extension section 4221 side of the lower rolling wheel group. It should be noted that the height of the bag opening station is slightly higher than the height of the upper end surface of the extension section 4221, that is, when the upper suction cup assembly 321 and the lower suction cup assembly 322 adsorb and open the ziplock bag opening, the bottom surface height of the ziplock bag is not lower than the height of the upper end surface of the extension section 4211; when the horizontal reciprocating pushing mechanism 233 drives the accommodating cylinder 221, the push rod 2311 and the push rod driving mechanism 231 to move toward the ziplock bag 600, so that the opening on the side of the accommodating cylinder 221 away from the push rod 2311 enters the ziplock bag from the bag mouth, the push rod driving mechanism 231 will force the plasticine in the accommodating chamber to be discharged into the ziplock bag from the opening on the side of the accommodating chamber away from the push rod 2311. When the bag is stopped, the clay gradually fills up the bottom of the ziplock bag first. During the filling process, the clay gradually expands the ziplock bag and fills up the bottom of the ziplock bag while the accommodating tube 221 is still injecting clay into the ziplock bag. The newly injected clay pushes the bottom of the ziplock bag to move away from the accommodating tube 221, that is, the ziplock bag as a whole moves away from the accommodating tube 221. The distance between the extension section 4221 and the accommodating tube 221 is set. Then, when the clay in the accommodating tube 221 is completely injected into the ziplock bag, the ziplock bag just falls onto the extension section 4221. As the lower conveyor belt runs, the ziplock bag filled with clay is delivered into the sealing assembly.

[0045] It should be noted that, multiple filling components 200 and bag opening components 300 can be mirror-set according to the actual needs of the production line. By adjusting the running speed of the sealing component 400, each filling component 200 and bag opening component 300 can be flattened and sealed by the sealing component 400 together with the filled ziplock bag.

[0046] In consideration of simplifying the equipment structure and controlling the equipment cost, a plurality of lower suction cup assemblies 32 can be fixedly mounted on the lower suction cup assembly fixing plate 323, and then the lower suction cup assembly fixing plate 323 is fixedly mounted on the output end of the suction cup vertical reciprocating motion mechanism 324, so that each lower suction cup assembly 32 can be driven to move up and down synchronously when the suction cup vertical reciprocating motion mechanism 324 is in motion. In addition, a plurality of accommodating cylinders 221, push rods 2311, and push rod driving mechanisms 231 can also be fixedly mounted side by side on the horizontal fixed plate 234, the horizontal fixed plate 234 is fixedly mounted on the output end of the horizontal reciprocating pushing mechanism 233, and a slide rail 232 is arranged between the horizontal fixed plate 234 and the frame 100, so that each accommodating cylinder 221, push rod 2311, and push rod driving mechanism 231 can be driven to move synchronously when the horizontal reciprocating pushing mechanism 233 is in motion. Preferably, the accommodating cylinder 221 is fixedly mounted on the horizontal fixed plate 234 through a fixing seat 222.

[0047] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
