The shortcoming of this patent is that, since the viscous syrup flows relatively slowly, not only the discharge speed is low, but also solidification and blockage may easily occur during the discharge process.

[0004] In summary, there is a need for a sugar painting machine that can increase the syrup discharge speed. Summary of the invention

[0005] The present invention aims to overcome the shortcomings of the prior art that the viscous syrup flows slowly, not only has a low discharging speed, but also is prone to solidification and blockage during the discharging process, and provides a sugar painting machine that can increase the syrup discharging speed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A sugar painting machine comprises a machine base, wherein a platform and a molten sugar tank are provided on the machine base, a drawing board is installed on the platform, the drawing board and the platform are slidably connected front and back, a gantry is also fixed on the platform, the drawing board is located below the gantry, a lifting seat is installed on the gantry, the lifting seat and the gantry are slidably connected left and right, the molten sugar tank is installed below the lifting seat and is slidably connected thereto up and down, a rotating rod is provided inside the molten sugar tank, the rotating rod and the molten sugar tank are rotatably connected, one end of the rotating rod is installed on the top of the molten sugar tank, a discharging nozzle is provided at the bottom of the molten sugar tank, the other end of the rotating rod is installed inside the discharging nozzle, a spiral extrusion block is provided on the rotating rod, the spiral extrusion block is placed on the inner side of the discharging nozzle, and the molten sugar tank is also provided inside A pressure plate, wherein the pressure plate and the molten sugar tank are movably connected up and down, a guide screw hole is provided on the pressure plate, a guide thread matching the guide screw hole is provided on the rotating rod, the rotating rod is connected to the pressure plate through the cooperation of the guide screw hole and the guide thread, a fixing rod is fixed in the molten sugar tank, the fixing rods are respectively placed on both sides of the rotating rod, a fixing rod through hole matching the fixing rod is provided on the pressure plate, the fixing rod is placed in the fixing rod through hole and movably connected with the fixing rod up and down, the material of the fixing rod is electric heating material, a pressure plate conductor in contact with the fixing rod is provided on the pressure plate, one of the fixing rods is electrically connected to the other fixing rod through the pressure plate conductor, a positive contact is provided at the bottom of one of the fixing rods, and a negative contact is provided at the bottom of the other fixing rod.

[0008] When the syrup is discharged, the pressing plate automatically moves downward, pressing the syrup in the molten sugar tank from top to bottom, so that the syrup can flow quickly to the discharge nozzle under pressure. At the same time, under the transmission cooperation of the guide screw hole 1 and the guide thread 1, the movement of the pressing plate will drive the rotating rod and the spiral extrusion block thereon to rotate automatically, so that the syrup at the discharge nozzle can be discharged quickly under the rotation and diversion of the spiral extrusion block, which greatly improves the discharge speed of the syrup, and well avoids the situation of solidification and blockage at the discharge nozzle caused by the slow flow of the syrup. In addition, the rotating stirring of the spiral extrusion block can also improve the mixing effect of the syrup and various additives. When drawing sugar, the drawing board automatically slides back and forth on the platform under the control of the driving device (such as a motor), the lifting seat and the molten sugar tank thereon automatically slide left and right on the gantry under the control of the driving device (such as a motor), and the molten sugar tank on the lifting seat automatically slides up and down under the control of the driving device (such as a motor). The positive and negative poles of the external power supply are connected to the positive contact and the negative contact respectively, so that the power supply, one of the fixed rods, the pressure plate conductor and the other fixed rod form a complete circuit, thereby realizing circuit conduction, thereby energizing the fixed rod and causing the fixed rod to heat up to melt the sugar. Since the two fixed rods are connected through the pressure plate conductor on the pressure plate, and the positive contact and the negative contact are both located at the bottom of the fixed rod, the electric heating part on the fixed rod is always below the pressure plate. Therefore, when the syrup gradually flows out of the molten sugar tank as the pressure plate is pressed downward, the electric heating part on the fixed rod also decreases as the liquid level of the syrup drops, which effectively avoids the dry burning of the upper part of the fixed rod and also improves the energy utilization efficiency.

[0009] Preferably, the pressing plate is also provided with a rotating block matching the fixed rod, the rotating block is mounted on the lower end surface of the pressing plate and is rotatably connected thereto, the rotating block is provided with two guide screw holes, the fixed rod is provided with two guide threads matching the two guide screw holes, the fixed rod is connected to the rotating block through the cooperation of the two guide threads and the two guide screw holes, and a plurality of stirring rods are fixed on the side wall of the rotating block. When the pressing plate moves downward, the rotating block on the pressing plate also moves downward along the fixed rod, and under the transmission cooperation of the two guide screw holes and the two guide threads, the rotating block itself rotates while moving downward, so that the stirring rod on the rotating block can rotate and stir the syrup in the molten sugar tank, further improving the mixing effect of the syrup and various additives.

[0010] Preferably, an annular mounting block is fixed at the edge of the upper end face of the rotating block, the second guide screw hole is placed on the inner side of the annular mounting block, an annular mounting groove matching the annular mounting block is provided on the lower end face of the pressing plate, the rotating block is mounted on the lower end face of the pressing plate and rotatably connected thereto through the cooperation of the annular mounting block and the annular mounting groove, a sealing sheet is fixed at the notch of the annular mounting groove, and the sealing sheet is placed on the contact surface between the annular mounting groove and the annular mounting block. The cooperation design of the annular mounting block and the annular mounting groove facilitates the installation of the rotating block on the pressing plate, guides the movement of the rotating block, and improves the movement accuracy. The design of the sealing sheet can prevent syrup from penetrating into the annular mounting groove.

[0011] Preferably, the rotating block is provided with a rotating block conductor, the pressing plate is provided with a pressing plate conductor in contact with the rotating block conductor, one end of the rotating block conductor is in contact with the fixed rod, and the other end of the rotating block conductor is in contact with the pressing plate conductor, and one of the fixed rods is electrically connected to another fixed rod through one of the rotating block conductors, the pressing plate conductor, and another rotating block conductor in sequence. An external power supply, one of the fixed rods, one of the rotating block conductors, the pressing plate conductor, another rotating block conductor, and another fixed rod form a complete circuit, thereby realizing circuit conduction, thereby energizing the fixed rod, causing the fixed rod to heat up to melt the sugar block.

[0012] Preferably, the upper end surface of the pressing plate is provided with a plurality of bowl-shaped grooves, the guide screw hole 1 and the fixing rod through hole are both located on the bottom surface of the bowl-shaped groove, and the pressing plate is also provided with an electric heating block in contact with the pressing plate conductor. Through the design of the bowl-shaped groove, the syrup remaining on the upper end surface of the pressing plate can flow along the inclined surface of the bowl-shaped groove to the bottom of the bowl-shaped groove, and fall to the bottom of the molten sugar tank through the guide screw hole 1 and the fixing rod through hole at the bottom of the bowl-shaped groove, thereby preventing the formation of liquid accumulation on the upper end surface of the pressing plate. Through the design of the electric heating block, the syrup on the upper end surface of the pressing plate can be heated to prevent the syrup from solidifying on the upper end surface of the pressing plate.

[0013] Preferably, a driving cylinder connected to a pressing plate is installed on the top of the molten sugar tank, a weight sensor is arranged at the bottom of the molten sugar tank, the weight sensor is electrically connected to the driving cylinder, and a feeding port is arranged on the side wall of the molten sugar tank. The weight sensor is used to detect the remaining amount of syrup in the molten sugar tank. When the amount of syrup in the molten sugar tank is insufficient to draw a complete sugar painting, the weight sensor will send a reset signal to the driving cylinder, so that the driving cylinder drives the pressing plate to reset and rise above the feeding port, so that the staff can smoothly add sugar blocks to the bottom of the molten sugar tank through the feeding port. The structure is simple, the control is convenient, and the degree of automation is high, which can well avoid the situation where the syrup runs out halfway through the sugar painting.

In the natural state, the lock pin on the slider is stuck in the lock groove on the feeding port, and the door body is in a locked state at this time, which can prevent personnel from opening the door by mistake and causing internal heat diffusion and loss; when the weight sensor detects that the amount of syrup in the sugar bowl is insufficient, the driving cylinder will drive the pressing plate to reset and rise. When the pressing plate passes the position of the slider during the rising process, the magnetic block 1 and the magnetic block 2 will attract each other, so that the pressing plate absorbs the slider and drives the slider to move upward together, and fix the slider at the upper end wall of the slide groove under the card connection of the card head and the card groove, so that the lock pin on the slider automatically disengages from the lock groove, and the locking state of the door body is released, so that the staff can smoothly open the door body for feeding operation; when the feeding is completed, the weight sensor sends a working signal to the driving cylinder according to the increased weight of the sugar block, and the driving cylinder drives the pressing plate to move downward along the fixed rod to the corresponding electric heating position. When the pressing plate passes the position of the slider during the descent process, the magnetic block 1 and the magnetic block 2 are attracted again, so that the pressing plate absorbs the slider and drives the slider to move downward together, so that the lock pin on the slider is re-engaged in the lock groove, and the door body is re-locked.

The cooperation between the first pressing slope and the second pressing slope guides the lock pin to enter the lock slot, and the door body can be pressed against the feeding port by the extrusion between the first pressing slope and the second pressing slope, thereby further improving the sealing performance between the door body and the feeding port.

A water cooling chamber 41 is provided inside the drawing board 2, and a water inlet 42 and a water outlet 43 are respectively provided on both sides of the water cooling chamber 41.

[0036] When the syrup is discharged, the driving cylinder 22 drives the pressing plate 7 to move downward automatically, pressing the syrup in the molten sugar tank 3 from top to bottom, so that the syrup can flow quickly to the discharge nozzle 5 under the action of pressure. At the same time, under the transmission cooperation of the guide screw hole 1 8 and the guide thread 1 9, the movement of the pressing plate 7 will drive the rotating rod 4 and the spiral extrusion block 6 thereon to rotate automatically, so that the syrup at the discharge nozzle 5 can be discharged quickly under the rotation and flow guidance of the spiral extrusion block 6.

[0038] When the amount of syrup in the molten sugar tank 3 is insufficient to draw a complete sugar painting, the weight sensor 23 will send a reset signal to the driving cylinder 22, so that the driving cylinder 22 drives the pressing plate 7 to reset and rise to the top of the feeding port 24, so that the staff can smoothly add sugar blocks to the bottom of the molten sugar tank 3 through the feeding port 24. In the natural state, the locking pin 28 on the slider 27 is stuck in the locking groove 29 on the feeding port 24, and the door body 25 is in a locked state at this time, which can prevent the staff from opening it by mistake and causing the internal heat to diffuse and lose; when the weight sensor 23 detects that the amount of syrup in the molten sugar tank 3 is insufficient, the driving cylinder 22 will drive the pressing plate 7 to reset and rise. When the pressing plate 7 passes the position of the slider 27 during the rising process, the magnetic block 1 32 and the magnetic block 2 33 will attract each other, so that the pressing plate 7 absorbs the slider 27, drives the slider 27 to move upward together, and fixes the slider 27 at the upper end wall of the slide groove 26 under the clamping cooperation of the clamp head 30 and the clamping groove 31, so that the slider 27 on the slider 27 The locking pin 28 automatically disengages from the locking groove 29, releasing the locking state of the door body 25 so that the staff can smoothly open the door body 25 to add materials; when the adding is completed, the weight sensor 23 sends a working signal to the driving cylinder 22 according to the increased weight of the sugar cubes, and the driving cylinder 22 drives the pressing plate 7 to move downward along the fixed rod 10 to the corresponding electric heating position. When the pressing plate 7 passes the position of the slider 27 during the descending process, the magnetic block 1 32 and the magnetic block 2 33 are re-attracted, so that the pressing plate 7 absorbs the slider 27, driving the slider 27 to move downward together, so that the locking pin 28 on the slider 27 is re-engaged in the locking groove 29, and the door body 25 is re-locked.
