Description

Technical Field

[0001] The present application relates to the technical field of filling equipment, and in particular to a weighing filling machine. Background Art

[0002] After candy products are filled into bottles, they need to be wrapped with aluminum foil at the bottle mouth to isolate them from the air and prevent them from getting damp and deteriorating.

[0003] Due to production requirements, some soft candies require a full coating of powdered sugar (white sugar). During the filling and dropping process, the powdered sugar can easily splash onto the bottle neck due to collisions with the candies. This powdered sugar cane can severely hinder the subsequent heat sealing or pressing of the aluminum foil during packaging, resulting in a loose foil seal and seal failure, which in turn affects the quality of the candies. Currently, this issue is typically addressed by manually cleaning the powdered sugar from the bottle neck after filling. This is done by brushing each remaining powdered sugar residue off the bottle neck.

[0004] With regard to the above-mentioned related technologies, after filling, sugar-coated candies still need to be manually cleaned by brushing off the sugar powder at the mouth of the packaging bottle with a brush. On the one hand, this is inefficient, and on the other hand, it is very easy to cause secondary contamination to the candies in the packaging bottles. Summary of the Invention

[0005] In order to facilitate the filling of sugar-coated soft candies and to facilitate the cleaning of sugar powder remaining at the mouth of the packaging bottle during filling, the present application provides a weighing filling machine.

After the transfer conveying assembly conveys the packaging bottles to the filling station, the weighing and filling assembly weighs and quantitatively fills the candies into the packaging bottles. Subsequently, the packaging bottles reach the discharging conveyor belt through the output end of the transfer conveying assembly and are continuously conveyed by the discharging conveyor belt. During this period, a vacuum pump is used to evacuate the suction pipe through a vacuum tube. When the packaging bottles conveyed by the discharging conveyor belt pass by the pipe orifice end of the suction pipe, the suction pipe generates a negative pressure air flow to suck off the sugar powder adhering to the bottle mouth of the packaging bottle, so that when the packaging bottle is subsequently sealed, the aluminum foil can be firmly sealed at the bottle mouth of the packaging bottle.

[0038] The transfer and conveying assembly 21 includes a frame 210, a conveying turntable 211 and a rotary driving member. The conveying turntable 211 is rotatably arranged on the frame 210, and the rotary driving member is drivingly connected to the conveying turntable 211 and is used to drive the conveying turntable 211 to rotate. In this embodiment, the rotary driving member adopts a reduction motor.

[0039] Refer to Figure 1 and Figure 2 , a plurality of groups of bottle clamping parts are arranged around the outer periphery of the conveying turntable 211, and the plurality of groups of bottle clamping parts are uniformly arranged around the axial direction of the conveying turntable 211. Each group of bottle clamping parts includes two bottle clamping notches 212 opened on the outer periphery of the conveying turntable 211. The bottle clamping notches 212 are arc-shaped and are used for the packaging bottles to be clamped in.

[0040] The output end of the feeding conveyor belt 1 and the input end of the discharging conveyor belt 3 both extend to the bottom of the conveying turntable 211 and both have a gap with the conveying turntable 211. The feeding conveyor belt 1 and the discharging conveyor belt 3 are arranged opposite to each other.

[0041] An arc-shaped bottle guiding plate 213 is also supported at the bottom of one side of the conveying turntable 211; there is a gap between the arc-shaped bottle guiding plate 213 and the conveying turntable 211. The two ends of the arc-shaped bottle guiding plate 213 are respectively connected to the input end of the feeding conveyor belt 1 and the output end of the discharging conveyor belt 3. The projection of the arc-shaped bottle guiding plate 213 on the horizontal plane covers the bottle clamping part on the conveying path of the conveying turntable 211. The arc-shaped bottle guiding plate 213, the feeding conveyor belt 1 and the discharging conveyor belt 3 are arranged at the same height.

[0042] Refer to Figure 1 and Figure 2 As shown in FIGS.

[0043] Refer to Figure 3 and Figure 4 As shown in FIGS.

[0044] Subsequently, when the conveying turntable 211 rotates to make the bottle clamping part located at the output end of the feeding conveyor belt 1, the two clamping notches of the bottle clamping part are respectively arranged opposite to the two discharging ends of the three-way distributor 222. The two sides of the feeding conveyor belt 1 are both supported with retaining rods. The feeding conveyor belt 1 is supported with a partition strip 10 through a frame body, and the partition strip and the feeding conveyor belt 1 are arranged in parallel. There is a gap between the partition strip 10 and the conveying surface of the feeding conveyor belt 1. The partition strip 10 is located on the center line of the feeding conveyor belt 1 to divide the feeding conveyor belt 1 into two mutually parallel feeding channels 101. When the conveying turntable 211 rotates to make the bottle clamping part located at the output end of the feeding conveyor belt 1, the two bottle clamping notches 212 of the bottle clamping part are respectively arranged opposite to the two feeding channels 101.

[0044] Refer to Figure 3 Subsequently, when the conveying turntable 211 rotates to make the bottle clamping part located at the output end of the feeding conveyor belt 1, the two packaging bottles are respectively input into the two clamping notches of the bottle clamping part of the conveying turntable 211 through the two feeding channels 101 by the feeding conveyor belt 1; after the weighed candies are filled into the packaging bottles located in the bottle clamping notches 212 through the cooperation of the multi-head scale 221 and the three-way distributor 222, the conveying turntable 211 rotates to drive the next controlled bottle clamping part to move into the output end of the feeding conveyor belt 1; at the same time, the bottle clamping part with the filled packaging bottle is moved into the arc-shaped baffle. After the bottle clamping part with the filled packaging bottle is moved from the arc-shaped baffle into the input end of the discharging conveyor belt 3, the discharging conveyor belt 3 takes out the packaging bottle from the bottle clamping notch 212 and further conveys it.

[0045] Refer to Figure 3and Figure 4 At the input end of the feeding conveyor belt 1, an anti - tipping bottle assembly is provided. Specifically, the anti - tipping bottle assembly includes a limit baffle 11 and an anti - tipping bottle driving member. The anti - tipping bottle driving member includes a first cylinder 12. The first cylinder 12 is supported on one side of the feeding conveyor belt 1 and is oriented towards the feeding conveyor belt 1. The limit baffle 11 is connected to the end of the piston rod of the limit cylinder. After the feeding conveyor belt 1 conveys two packaging bottles to two clamping notches in the clamping portion at the output end of the feeding conveyor belt 1 through two feeding channels 101 respectively, the first cylinder 12 drives the limit baffle 11 to move, so that the limit baffle 11 blocks the output ports of the two feeding channels 101 and blocks the two bottle - clamping notches 212 of the clamping portion at the same time. On the one hand, it is beneficial to limit the subsequent conveyed packaging bottles from impacting and colliding with the packaging bottles in the bottle - clamping notches 212. On the other hand, it is beneficial to limit the situation where the packaging bottles located in the bottle - clamping notches 212 are displaced and toppled due to the conveying of the feeding conveyor belt 1 and the impact of filling candies. It is beneficial for the weighing and filling assembly 22 to better fill candies into the packaging bottles.

[0046] Refer to Figure 1 and Figure 2 As shown in FIG. and FIG., a material guiding portion 214 is connected to the corresponding bottle - clamping portion of the conveying turntable 211. The material guiding portion 214 includes a connecting plate 2141 and two material guiding funnels 2142. The connecting plate 2141 is connected to the conveying turntable 211. The material guiding funnels 2142 are in the shape of a large - top - and - small - bottom cone. The two material guiding funnels 2142 are connected to the connecting plate 2141, and the two material guiding funnels 2142 are respectively arranged opposite to the two bottle - clamping notches 212 of the bottle - clamping portion. When the packaging bottle is clamped into the bottle - clamping notch 212, there is a gap between the bottom end of the material guiding funnel 2142 and the bottle mouth of the packaging bottle. Through the setting of the material guiding funnel 2142, during the subsequent process of filling candies into the packaging bottle, the material guiding funnel 2142 can be used to centrally guide and limit the candies entering the packaging bottle, so that the candies can fall into the packaging bottle more accurately, and the sugar powder carried by the candies splashing and spilling onto the bottle mouth end of the packaging bottle is reduced.

[0047] The material guiding portion 214 further includes a collecting groove 2143. The collecting groove 2143 is connected to the tops of the two material guiding funnels 2142 and is communicated with the top ports of the two material guiding funnels 2142. The collecting groove 2143 is used to intercept the sputtered sugar powder during the filling process to limit the sugar powder from falling onto the feeding conveyor belt 1 and the conveying turntable 211, causing pollution. In this embodiment, the material guiding portion 214 is integrally made of stainless steel material.

[0048] A number of vibration motors 2132 are installed at the bottom of the arc-shaped bottle conveying plate 213. When the subsequent conveying turntable 211 rotates to drive the packaging bottles onto the arc-shaped bottle conveying plate 213, the vibration motors 2132 drive the packaging bottles inside the arc-shaped bottle to vibrate, so that the candies at the bottle mouth end of the packaging bottles are evenly filled into the packaging bottles, and when restricting the subsequent packaging bottles from moving out of the bottle jamming notch 212, the candies at the bottle mouth end of the packaging bottles do not interfere with the feeding funnel 2142. At the same time, it can assist in shaking off and cleaning the powdered sugar at the bottle mouth end of the packaging bottles.

The arc-shaped bottle protection plate 2131 is used to prevent the packaging bottles from falling off the arc-shaped bottle conveying plate 213 during the vibration process, which is beneficial to the stable conveying of the packaging bottles. A number of support rods 2133 are vertically connected to the bottom of the arc-shaped bottle conveying plate, and the bottom ends of the support rods 2133 are fixedly connected to the frame 210 through rubber blocks 2134.

[0050] Refer to Figure 5 and Figure 6 As shown in

[0051] Powdered sugar collection trays 5 with openings facing down are provided at the bottoms of the feeding conveyor belt 1 and the discharging conveyor belt 3. The powdered sugar collection trays 5 are respectively arranged to cover the corresponding discharging conveyor belts 3, and the powdered sugar collection trays 5 are used to collect the powdered sugar that falls during the conveying processes of the feeding conveyor belt 1 and the discharging conveyor belt 3, reducing the scattering and pollution of the powdered sugar.

[0052] Refer to Figure 5 and Figure 6, the cleaning mechanism 4 includes a vacuum tube 41 and a vacuum pump, and the vacuum tube 41 is connected to the vacuum pump. The vacuum tube 41 is fixed outside the discharge conveyor belt 3. A plurality of suction tubes 42 are connected to the outer periphery of the vacuum tube 41. In this embodiment, the suction tubes 42 are made of universal bellows tubes. One end of each suction tube 42 far from the vacuum tube 41 is connected to a flat suction head 43. One end of each suction tube 42 far from the vacuum tube 41 extends above the discharge conveyor belt 3. The vacuum pump is used to evacuate the suction tubes 42 through the vacuum tube 41. When the packaging bottles conveyed by the discharge conveyor belt 3 pass by the nozzle ends of the suction tubes 42, the sugar powder adhered to the bottle mouths of the packaging bottles is sucked away by the negative pressure air flow at the nozzle ends of the suction tubes 42, so as to clean the sugar powder at the bottle mouth ends of the packaging bottles.

[0053] During actual use, before filling the candies, the positions of the suction tubes 42 are adjusted in advance so that the nozzle ends of the suction tubes 42 cooperate to cover the conveying path of the discharge conveyor belt 3, so that when the packaging bottles pass under the suction tubes 42, the sugar powder adhered to the bottle mouth ends of the packaging bottles can be better sucked away by the negative pressure air flow generated by the suction tubes 42.

[0054] The implementation principle of the embodiment of the present application is as follows: Packaging bottle in place: The rotary driving member is used to drive the conveying turntable 211 to rotate. When the conveying turntable 211 rotates to a position where the bottle clamping portion faces the feeding conveyor belt 1, the two packaging bottles are conveyed to the bottle clamping notches 212 of the bottle clamping portion through the two feeding conveying channels 101 of the feeding conveyor belt 1; the first cylinder 12 of the anti-tipping bottle assembly is used to drive the limit baffle 11 to block the output ports of the two feeding conveying channels 101 of the feeding conveyor belt 1 and block the two bottle clamping notches 212 of the bottle clamping portion.

[0055] Candy filling: The multi-head scale 221 cooperates with the three-way distributor 222 to pour the weighed and quantified candies into the packaging bottles at the bottle clamping portion at the output end of the feeding conveyor belt 1.

[0056] Packaging bottle conveying: The rotary driving member is used to drive the conveying turntable 211 to rotate to drive the filled packaging bottles into the arc-shaped bottle guiding plate 213. During this period, the vibration motor at the bottom of the arc-shaped bottle guiding plate 213 is used to vibrate the packaging bottles to shake off the sugar powder at the bottle mouth ends of the packaging bottles and level the candies filled in the packaging bottles.

[0057] Packaging bottle transfer: When the rotating clamping portion of the conveying turntable 211 is located at the output end of the discharge conveyor belt 3, the second cylinder 31 of the bottle discharging assembly is used to drive the two bottle discharging push rods 32 to cooperate with the discharge conveyor belt 3 to move the packaging bottles in the clamping notches out of the bottle clamping notches 212.

[0058] Cleaning the mouth end of the packaging bottle: When the packaging bottle conveyed by the discharging conveyor belt 3 passes below the suction pipe 42 of the cleaning mechanism 4, the negative pressure air flow generated by the suction pipe 42 is used to suck the sugar powder adhered to the mouth of the packaging bottle, so as to clean the sugar powder at the mouth end of the packaging bottle.

[0059] This application can realize the automatic weighing and filling of candies, and clean the sugar powder remaining at the mouth end of the packaging bottle during filling, so as to facilitate subsequent aluminum foil packaging, and effectively improve the overall filling production efficiency of candies.
