Description

Technical Field

[0001] The utility model relates to the field of filling machines, in particular to a contact filling valve used in a fruit particle suspension beverage filling machine. Background Art

[0002] When filling fruit suspension beverages, it is necessary to first fill the fruit particles in the bottle, and then fill the syrup in the bottle containing the fruit particles. When filling the syrup, a rotary filling machine is generally used in conjunction with a plunger filling valve for filling. The cam ring mechanism in the rotary filling machine drives the bottle to rise and fall and the plunger filling valve to open and close. However, the traditional plunger filling valve has the following defects: 1. After a long period of operation, the piston in the piston cylinder is prone to resonate with the piston cylinder, causing the piston cylinder to deflect, which will affect the operation of the piston in the piston cylinder. 1. When filling the bottle, the plunger canning valve and the bottle cannot form a sealed contact. When filling the bottle with fruit particles, the syrup will not only contact with the fruit particles to form a large number of bubbles, but also form a large liquid level fluctuation. Therefore, when the plunger canning valve and the bottle cannot form a sealed contact, bubbles and fruit particles are easy to overflow from the bottle mouth, which will not only reduce the fruit content, but also cause the bottle mouth to be contaminated and cause sugar spots and mildew.

[0022] When the first guide wheel 243 moves along the cam ring located at the top of the rotary filling machine, the cam ring will guide the first guide wheel 243 to move up and down in the guide groove 212. At this time, the first guide wheel 243 drives the guide sleeve 24 to rise and fall in the upper cylinder body 21, and the guide sleeve 24 drives the piston 23 to rise and fall synchronously in the lower cylinder body 22 through the piston rod 25. When the piston 23 and the piston rod 25 are lifted and lowered in the lower cylinder body 22, they are replaced with the outside air through the ventilation hole 221 to ensure that the piston 23 can be lifted and lowered smoothly. The guide sleeve 24 and the piston 23 connected by the piston rod 25 are respectively sealed and slidably arranged in the upper cylinder body 21 and the lower cylinder body 22. Compared with setting a single piston structure, the operation is more stable. The fixed plate 211 is arranged between the upper cylinder body 21 and the material cylinder 1, which can play a fixed supporting role for the piston cylinder 2 through the material cylinder 1, thereby improving the stability of the piston cylinder 2 and preventing the piston cylinder 2 from deflecting due to resonance after a long period of lifting and lowering.

[0023] A distributor 3 is sealed and connected to the bottom of the lower cylinder body 22 of the piston cylinder 2, a distributor chamber 31 is provided in the distributor 3, an upper through hole 32 connected to the lower cylinder body 22 is provided on the upper side wall of the distributor chamber 31, a lower through hole 33 is provided on the lower side wall of the distributor chamber 31, the distributor chamber 31 in the distributor 3 is connected to the discharge port of the cylinder 1, a sealing sleeve 34 is sealed and provided in the distributor chamber 31, middle holes aligned with the upper through hole 32 and the lower through hole 33 are provided on the upper and lower side walls of the sealing sleeve 34, a switching handle 6 is provided in the sealing sleeve 34 for sealing rotation, and a square shaft is provided on the switching handle 6 61, a connecting plate 62 is arranged on the square shaft 61, and a second guide wheel 63 is arranged on the connecting plate 62. The second guide wheel 63 cooperates with the cam ring located at the bottom of the rotary filling machine. When the second guide wheel 63 moves along the cam ring located at the bottom of the rotary filling machine, the cam ring guides the second guide wheel 63 to move up and down. The second guide wheel 63 that moves up and down can drive the switching handle 6 to reciprocate through the connecting plate 62. The switching handle 6 is respectively provided with a discharge channel 64 and a feed channel 65. The discharge channel 64 vertically penetrates the circumferential side wall of the switching handle 6, and the feed channel 65 extends from the circumferential side wall. The right side wall of the switching handle 6 is obliquely penetrated, and a <-shaped groove 66 connected to the feed channel 65 is arranged on the right side wall of the switching handle 6. The <-shaped groove 66 is arranged to increase the contact surface between the feed channel 65 and the syrup in the dispensing chamber 31, and improve the absorption of the syrup by the feed channel 65. A fan-shaped groove 67 with a central angle of 90° is arranged on the left side wall of the switching handle 6, and the center of the fan-shaped groove 67 is located on the axis of the switching handle 6. A limiting pressure plate 35 is arranged on the distributor 3, and the limiting pressure plate 35 abuts against the fan-shaped groove 67 to limit the rotation angle of the switching handle 6, so that the switching handle 6 can only rotate 90° at most. °, so that it can be ensured that the discharge channel 64 or the feed channel 65 can be aligned with the corresponding middle hole, one end of the discharge channel 64 is located on the same side as one end of the fan-shaped groove 67, and one end of the feed channel 65 is located on the circumferential side wall of the switching handle 6 is located on the same side as the other end of the fan-shaped groove 67. When the switching handle 6 rotates the discharge channel 64 to a longitudinal state, the discharge channel 64 is connected to the two middle holes on the sealing sleeve 34. When the switching handle 6 rotates the feed channel 65 to a longitudinal state, one end of the feed channel 65 located on the circumferential side wall is connected to the middle hole on the sealing sleeve 34 that is aligned with the upper through hole 32. Since both the discharge channel 64 and the feed channel 65 need to be connected to the same middle hole, it is necessary to strictly control the apertures of the discharge channel 64 and the feed channel 65 to prevent them from being pierced through and connected and being scrapped. In actual production, after controlling the apertures of the discharge channel 64 and the feed channel 65, there is a slight misalignment between the discharge channel 64 and the middle hole on the upper side. A compensating slope 641 is provided on the end of the discharge channel 64 that is connected to the middle hole on the upper side. In this way, when there is a misalignment between the discharge channel 64 and the middle hole, it can play a role in drainage, thereby ensuring the discharge amount of the discharge channel 64.

[0024] A valve mouth 4 and a barrier seat 5 are provided at the bottom of the distributor 3. The valve mouth 4 is communicated with the lower through hole 33 of the distributor 3 and is located in the barrier seat 5. An exhaust hole 51 is provided on the side wall of the barrier seat 5. A compensating sealing gasket 52 is provided at the bottom of the barrier seat 5. An inclined convex ring 521 is extended downwardly from the bottom wall of the compensating sealing gasket 52. When the bottle 7 moves upward for filling, the compensating sealing gasket 52 can compensate for the original distance between it and the bottle mouth of the bottle 7, so that the bottle mouth can abut against the compensating sealing gasket 52 to form a sealing contact, and the inclined convex ring 521 can extend into the bottle mouth and fit with the inner wall of the bottle mouth, further improving the sealing performance between the compensating sealing gasket 52 and the bottle mouth, thereby preventing bubbles or fruit particles from overflowing to contaminate the bottle mouth, and during the filling process, when the syrup replaces the air in the bottle 7, the air in the bottle 7 can be discharged outward from the exhaust hole 51 on the barrier seat 5 to achieve smooth filling.

[0025] When in use, when the switching handle 6 is rotated to the longitudinal state of the feed channel 65, the feed channel 65 is connected with the middle hole on the upper side of the sealing sleeve 34, and the discharge channel 64 is in a transverse state and is blocked by the sealing sleeve 34. At this time, the piston assembly rises in the piston cylinder 2 to form a negative pressure in the lower cylinder body 22, and the syrup in the material cylinder 1 passes through the powder cavity 31, the <-shaped groove 66, the feed channel 65, the middle hole on the upper side and the upper through hole 32 and enters the lower cylinder body 22. When the switching handle 6 is rotated 90° to the longitudinal state of the discharge channel 64, the discharge channel 64 is connected with the two middle holes in the sealing sleeve 33, and the feed channel 65 is in a transverse state. The end of the feed channel 65 located on the circumferential side wall is blocked. The sealing sleeve 34 is blocked, and the bottle 7 moves upward to seal and fit with the compensation sealing gasket 52. The inclined convex ring 521 on the compensation sealing gasket 52 extends into the bottle mouth of the bottle 7 and fits with the inner wall of the bottle mouth. The piston assembly descends in the piston cylinder 2 to push the syrup in the lower cylinder body 22 downward and discharge it, enters the valve mouth 4 through the discharge channel 64, and is finally filled into the bottle 77. The bubbles and floating fruit particles generated during the filling process are blocked by the compensation sealing gasket 52. After the filling is completed, the bottle is rotated and transported to separate from the sealing compensation sealing ring 52. The syrup in the bottle no longer churns, the bubbles gradually dissipate, and the fruit particles are stably suspended on the calm syrup liquid surface, and no syrup will remain on the outer wall of the bottle.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
