Description

Drum-type drip casting mechanism

Technical Field

The utility model relates to a roller type drip casting mechanism.

Background

In order to facilitate weighing and transporting chocolate materials, chocolate raw material manufacturers in the industry generally prepare chocolate raw pulp into block materials which are convenient to weigh and transport so as to be sold to chocolate food manufacturers, and after the chocolate food manufacturers obtain the block materials, the chocolate food manufacturers can be used for subsequent food pouring and forming processes only by heating and melting the block materials in actual production so as to prepare various chocolate foods.

As with the common chocolate cast food, the production of the chocolate block raw material also needs to use a core device of a casting mechanism, and the casting mechanism is matched with a conveying device and a cooling device to efficiently produce the chocolate block raw material with regular shape.

The pouring mechanism in the prior art is mainly a plunger pressurizing type pouring mechanism, and the pouring mechanism consists of a pouring head with a plurality of rows of valve cavities arranged inside, a pressurizing cavity arranged corresponding to the valve cavities, a plunger arranged in the pressurizing cavity and a plunger driving mechanism connected with and driving the plunger to move. The valve cavity is internally provided with a control valve core, the upper part of the valve cavity is provided with a feed inlet for receiving materials from the material cylinder, and the bottom of the valve cavity is provided with a pouring port. In practice, the pouring mechanism is arranged above the conveying equipment, and the slurry is poured on a travelling carrier of the conveying equipment through the pressurization of the plunger. For example, publication No. 109770027a discloses a chocolate casting machine, which is a chocolate block raw material production device designed by the applicant, and the core component of the chocolate block raw material production device is that a plunger pressurizing type casting mechanism is adopted to continuously cast heat-preserving chocolate raw slurry onto a belt conveyor moving downwards, a long solid material belt is formed through a cooling tunnel, and then the solid material belt is cut into chocolate block raw materials with regular specifications through a breaking mechanism at the rear stage.

However, according to customer feedback, the chocolate sheet material still has the following problems in practical application:

1. the volume is still large, and the long sheet structure is difficult to fully utilize the volume of the packaging bag, so that the packaging bag is not easy to package and transport. And the long flaky structure is easy to break, so that the look and feel of the product are affected, and the metering is puzzled.

2. The melting speed of the chocolate flake raw material is still slower, and the improvement of the production efficiency is affected.

There is a need in the chocolate food industry for a chocolate mass raw product that is smaller in size, easier to package and transport, and easier to melt. Through experiments, the industry now finds that if the chocolate raw material is made into small round cakes with the diameter of 10-40mm, the chocolate raw material is very favorable for packaging and transportation, and can also obtain very high melting efficiency. In order to obtain the small cake-shaped chocolate raw material, a plunger pressurizing type pouring mechanism is still adopted in the industry to be matched with a rolling belt to pour and produce, such as the existing chocolate sheet pouring machine. However, such devices have exposed the following problems in production:

in practice, little slurry is required to drop form individual patties, but since the existing plunger booster casting mechanism is a continuous casting mechanism, it is difficult to control the slurry flow from each casting head. Thus, during the pressurization stroke of the plunger, the casting head is often unable to quickly cut off the excess slurry, which results in the slurry often being overstocked on the belt and drawing out the slurry track on its surface as the belt moves, disrupting the shape of the patties.

In order to solve the problem, the current practice in the industry is to design a belt into an intermittent running mechanism, and intermittently pour a row of small cake-shaped chocolate raw materials by matching with the pouring mechanism, but the defect is obvious that the production efficiency is too low, and when the yield is large, a plurality of factories often need to adopt a plurality of devices for simultaneous operation production in order to improve the efficiency, so that the production cost of enterprises is greatly improved.

There is a need in the industry for a drip casting apparatus that is capable of producing the above-described cookie-shaped chocolate material very efficiently.

Disclosure of Invention

The utility model aims at: a roller-type drip casting mechanism is provided, which is more suitable for the casting production of small cake-shaped chocolate raw materials.

The technical scheme of the utility model is as follows: the roller type drip irrigation mechanism comprises a support frame and is characterized in that a drip irrigation roller is transversely arranged on the support frame, the drip irrigation roller comprises a feed pipe fixed on the support frame and a drip irrigation pipe sleeved outside the feed pipe, the drip irrigation pipe is rotationally assembled on the support frame and is driven by a drip irrigation pipe rotation driving device to rotate relative to the feed pipe, and drip irrigation holes are distributed on the pipe wall of the drip irrigation pipe in an array manner; the two ends of the feeding pipe are respectively used for feeding and discharging; the feeding device is connected with two ends of the feeding pipe through a pipeline; the bottom of the pipe wall of the feeding pipe is provided with a discharging cavity which is used for communicating the feeding pipe and a drip casting hole passing through the lower end of the discharging cavity along with the rotation of the drip casting pipe.

Of course, in actual design, the number and spacing of the drip holes in the axial and circumferential directions of the drip tube is limited by the width of the underlying belt and the circumference of the drip tube itself. For example, in one embodiment of the drip irrigation pipe, twenty sets of drip irrigation holes are axially provided, each set is composed of eighteen drip irrigation holes uniformly distributed on the periphery of the drip irrigation pipe at intervals, and the drip irrigation holes of adjacent sets are arranged in a staggered manner in the circumferential direction.

And a slurry receiving hopper can be arranged below the blanking port and used for receiving scraped slurry. The scraper structural design can ensure that the slurry remained on the surface of the drip hole is effectively removed, and the phenomenon that the slurry drips to pollute the surface of a travelling carrier (belt) of conveying equipment (such as a belt conveying mechanism) or is mixed with the slurry instilled in the subsequent drip hole to cause uneven quality of small round cakes is avoided.

Further, the feeding device comprises a material cylinder with a stirring mechanism and a heating device and a delivery pump, wherein the side surface of the lower part of the material cylinder is provided with a discharge hole, the discharge hole is connected with one end of the material conveying pipe through a discharge pipe, the delivery pump is arranged on the discharge pipe, the top of the material cylinder is provided with a first feed back hole, the first feed back hole is connected with the other end of the material conveying pipe through a first feed back pipe, the discharge pipe is provided with a first pressure control valve and a pressure display instrument positioned at the downstream position of the first pressure control valve, and the first feed back pipe is provided with a second pressure control valve.

By controlling the opening degrees of the first pressure control valve, the second pressure control valve and the third pressure control valve, a worker can adjust the pressure of chocolate mass entering the feeding pipe, and the slurry in the dripping hole is ensured to be discharged more smoothly during instillation.

Further, the rotary driving device comprises a main driving wheel driven by a motor speed reducer unit and a secondary driving wheel in driving connection with the main driving wheel; the outer circumferences of two ends of the drip irrigation pipe are respectively provided with a flange plate, the flange plate at one end of the drip irrigation pipe is fixed with the auxiliary transmission wheel, the flange plate at the other end of the drip irrigation pipe is fixed with the same supporting wheel, the inner side of the supporting wheel is sleeved outside the conveying pipe through an inner bearing of the supporting wheel, the periphery of the supporting wheel is arranged inside a rotating seat through an outer bearing of the supporting wheel, and the rotating seat is fixed on a supporting frame.

When the utility model is practically used, the utility model is the same as a conventional plunger booster type pouring mechanism, and the utility model needs to be matched with a conveying device and a cooling device for use. The present utility model is typically disposed above a traveling carrier of a conveyor apparatus, such as a belt disposed above a belt conveyor mechanism, and the belt is passed through a cooling tunnel as a conventional cooling apparatus to cool and shape chocolate mass dripped onto the belt.

The working principle of the utility model is as follows:

the chocolate mass is heated by a vat in the feed device and is stirred by an internal stirring mechanism.

The chocolate mass is then continuously transported into the feed tube through a conduit connected to both ends of the feed tube and circulated within the feed tube and the feed tube. The slurry is forced into a discharge cavity in the discharge insert due to pressure in the feed tube.

After a transfer device such as a belt conveyor is started, a belt as its traveling carrier is continuously transported forward. At this time, the upper drip irrigation pipe rotates, and when the drip irrigation holes in the same row in the axial direction of the drip irrigation pipe pass through the lower end of the discharge cavity of the discharge insert, the slurry is extruded out of the drip irrigation holes under the action of pressure and drips onto the belt in rows. Because the drip tube rotates continuously around the feed pipe, once the drip hole is misplaced with the lower end of the discharge cavity after the slurry is extruded out of the drip hole, the rear slurry is rapidly cut off, and no residual drops on the belt.

With the continuous rotation of the drip irrigation pipe, the slurry is dripped on the belt in rows, and is cooled by the cooling tunnel to form the required small cake-shaped chocolate raw material.

The utility model has the advantages that:

1. compared with the traditional plunger booster-type pouring mechanism, the roller-type pouring mechanism has the following two advantages in the pouring operation: firstly, the drip pouring action is completed by means of the alignment and dislocation of the drip pouring hole rotating along with the drip pouring pipe and the discharging cavity with pressure, so that under the continuous rotation of the drip pouring hole, once slurry is extruded out of the drip pouring hole, the rear slurry is rapidly cut off, and no excessive drip falls on a travelling carrier (such as a belt) of conveying equipment (such as a belt conveying mechanism), so that the shape of a product is not damaged by pulling out the slurry belt track on the surface of the travelling carrier. Secondly, due to the advantages of the dripping mechanism, the travelling carrier does not need to be matched with intermittent operation during production, but can keep continuous travelling, and the production efficiency of the device is far higher than that of the prior device for producing small cake-shaped chocolate raw materials in a large scale.

2. According to the drip irrigation roller design, the outer drip irrigation pipe and the inner conveying pipe are of completely separable structures, so that the outer drip irrigation pipe can be replaced conveniently, for example, the drip irrigation pipes with different array arrangement numbers and drip irrigation hole specifications can be replaced according to the requirements of customers, re-perforating is not needed, and the generation cost is saved greatly.

3. According to the utility model, the feeding pipe adopts a double-layer sleeve design, and the heat insulation interlayer can play a good heat insulation effect on chocolate slurry in the inner pipe, so that the problem that heat is quickly lost and becomes solidified and can not be instilled smoothly is avoided.

4. The scraper structure is specially designed, so that the slurry remained on the surface of the pouring hole can be effectively removed, and the phenomenon that the slurry drops pollute the surface of a travelling carrier (such as a belt) of conveying equipment (such as a belt conveying mechanism) or is mixed with the slurry instilled in the subsequent pouring hole to cause uneven quality of small round cakes is avoided. Meanwhile, the slurry scraped by the scraper can be reused, so that waste is avoided.

5. According to the feeding device, through controlling the opening degrees of the first pressure control valve, the second pressure control valve and the third pressure control valve, a worker can adjust the pressure of chocolate paste entering the feeding pipe, and the fact that the paste in the pouring hole is discharged more smoothly during instillation is ensured.

6. The drip casting roller has better stability in transmission design and positioning design, and can ensure that the drip casting roller works more stably and operates more reliably.
