Description

Technical Field

[0001] This utility model relates to the field of temperature control machines, and more particularly to a continuous temperature control machine with a detachable screw. Background Technology

[0002] A continuous temperature controller is a device that can continuously process materials and regulate their temperature. Unlike intermittent (batch) temperature controllers, it does not process a batch of materials at a time and then stop to process the next batch. Instead, materials continuously enter the equipment, undergo heating or cooling processes inside the equipment, and then continuously leave the equipment.

[0003] Traditional chocolate tempering machines often require the entire machine to be shut down for maintenance and cleaning because internal components such as screws are difficult to disassemble and clean individually. For example, Chinese Patent Publication No. CN208274021 U discloses a chocolate tempering and pouring machine, belonging to the field of tempering equipment. It includes a mold table, a pouring mold, a stirring and tempering mechanism, and a lifting mechanism. The pouring mold is freely placed on the mold table, the stirring and tempering mechanism is located on the mold table and used for melting and stirring the chocolate, and the lifting mechanism is connected to the stirring and tempering mechanism and used to transport the chocolate to the top of the mold table. The chocolate can fall into the pouring mold or the stirring and tempering mechanism for shaping or circulation. The stirring and tempering mechanism achieves batch and uniform stirring of the melted chocolate, thereby obtaining a uniform chocolate liquid.

[0004] Pipe fittings can be connected by multiple snap fasteners. For example, the prior art Chinese patent announcement number "CN219596963U" discloses a sand-removing nozzle that is easy to replace. It includes an inverted cone at the lower end of the hydrocyclone and an underflow port connected to the inverted cone. A sand-removing nozzle is provided on the inner side of the underflow port. A quick-release component is provided between the inverted cone and the underflow port. A retaining ring is provided on the outer surface of the top end of the underflow port and the outer surface of the bottom end of the inverted cone. A retaining ring is integrally formed on the outer surface of the top end of the sand-removing nozzle. The quick-release component replaces the original flange bolt connection. When replacing the sand-removing nozzle, one person can complete the replacement work, saving manpower.

[0005] In actual operation, the screw is rotatably connected inside the cylinder, and the top of the cylinder is usually connected to the geared motor by bolts and flanges. Therefore, when disassembling the screw, the bolts need to be removed one by one to separate the motor from the cylinder, which affects the disassembly efficiency of the screw. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of disassembling the screw, and to propose a continuous temperature control machine with a detachable screw.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a continuous temperature control machine with a detachable screw, including a temperature control machine body, a sleeve and a lifting screw. The temperature control machine body includes a temperature control cylinder set on a table and the sleeve fixedly connected inside the temperature control machine body. The bottom end of the sleeve is connected to the temperature control cylinder through a connecting pipe.

[0009] The lifting screw is rotatably connected inside the sleeve via a driving component. The top of the sleeve is fixedly connected to the driving component via a connecting assembly. The top of the sleeve, located around the connecting assembly, is also provided with an anti-accidental contact structure.

[0010] Furthermore, the connecting assembly includes a first connecting member, a second connecting member, and a third connecting member arranged concentrically. The first connecting member is fixedly connected to the top end of the sleeve. The shaft end of the lifting screw is interference-fitted with a bearing and a shaft seal. The bearing and the shaft seal are both interference-fitted into the shaft hole of the second connecting member. The bottom of one end of the driving member is fixedly connected to the third connecting member. The output end of the driving member is sleeved around the shaft end of the lifting screw and driven through a keyway.

[0011] Furthermore, the top circumference of the first connector is provided with a plurality of positioning pins, and the outer edges of the second connector and the third connector are provided with positioning holes corresponding to the positioning pins.

[0012] The first connector, the second connector, and the third connector are stacked sequentially by sealing gaskets and are circumferentially locked together by the positioning pins and the positioning holes.

[0013] Furthermore, the connecting assembly also includes a buckle, and at least one pair of corresponding protrusions and fixing parts are distributed on the outer circumference of the top of the third connector and the sleeve. The buckle is rotatably connected to the side of the fixing part, and the buckle has an eccentrically rotating ring located below the pivot, which is tightly engaged with the protrusion.

[0014] Furthermore, the anti-accidental touch structure includes a pair of oppositely arranged arc-shaped portions, which are closed and cover the periphery of the connecting component. The pair of arc-shaped portions are respectively provided with a first connecting portion and a second connecting portion on the upper and lower sides at both ends.

[0015] Furthermore, the outer wall of the second connector has a third connecting portion, and a pair of first connecting portions are disposed on the upper and lower sides of the third connecting portion. The pair of first connecting portions and the third connecting portion are hinged and rotated by a pin.

[0016] Furthermore, a pair of second connecting parts are staggered and concentrically arranged, with a plug rod slidably connected to the bottom of one of the second connecting parts by a spring, and the free end of the plug rod is inserted into the through hole of the other second connecting part.

[0017] The present invention discloses a continuous temperature control machine with a detachable screw, which has the following advantages: The present invention connects and fixes the lifting screw, the sleeve, and the geared motor through a connecting component. The method of using a buckle to hold the protrusion and the positioning pin to insert into the positioning hole can prevent the geared motor from driving the connecting parts to rotate freely. On the other hand, the screw and the geared motor can be easily disassembled by unlocking the buckle. In addition, a pair of arc-shaped parts are provided on the periphery of the connecting component. The pair of arc-shaped parts are hinged to the second connecting part and rotated. They are closed around the buckle by the insertion rod to prevent the buckle from accidentally disengaging from the protrusion in case of accidental contact. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5A continuous temperature control machine with a detachable screw includes a temperature control machine body 1, a sleeve 2 and a lifting screw 3. The temperature control machine body 1 includes a temperature control cylinder 4 set on a table and the sleeve 2 fixedly connected inside the temperature control machine body 1. The bottom end of the sleeve 2 is connected to the temperature control cylinder 4 through a connecting pipe 5.

[0026] The lifting screw 3 is rotatably connected inside the sleeve 2 via a driving component 6. The top of the sleeve 2 is fixedly connected to the driving component 6 via a connecting assembly 7. The top of the sleeve 2 is also provided with an anti-accidental contact structure 8 located around the connecting assembly 7.

[0027] In some embodiments, a cover is rotatably connected to the back of the temperature control unit body 1, and the internal components of the temperature control unit body 1, such as the sleeve 2 and the drive unit 6, can be directly operated by opening and closing the cover.

[0028] Specifically, a casting pipe is connected to the top of the sleeve 2, and the outlet end of the casting pipe extends to the top of the temperature regulating cylinder 4. After the sleeve 2 is separated from the connecting pipe 5, the casting pipe can be driven to detach from the main body 1 of the temperature regulating machine by moving the whole body upward, so as to facilitate the subsequent disassembly of the lifting screw 3, etc.

[0029] More specifically, the sleeve 2 and the connecting fitting 5 can be connected and fixed by the clamp connection method in the existing technology, so as to facilitate the separation between the sleeve 2 and the connecting fitting 5. An electric valve can also be installed between the sleeve 2 and the connecting fitting 5. More specifically, the sleeve 2 can be fixed to the inner wall of the temperature control machine body 1 by a U-shaped clamp, which further improves the stability of the sleeve 2.

[0030] It is worth mentioning that the temperature regulating cylinder 4 stirs the material through the internal heating unit and stirring unit. After the material melts, it enters the sleeve 2 through the connecting pipe 5. The driving component 6 is a geared motor. The geared motor drives the lifting screw 3 to rotate and lift the melted material. The conveyed material returns to the temperature regulating cylinder 4 through the pouring pipe, realizing the external circulation of the material.

[0031] It should be noted that the bottom of the temperature regulating cylinder 4 is also connected to an electric discharge pipe, and this embodiment is applicable to the processing of materials with a certain degree of fluidity, such as chocolate.

[0032] Furthermore, the connecting assembly 7 includes a first connecting member 71, a second connecting member 72, and a third connecting member 73 arranged concentrically. The first connecting member 71 is fixedly connected to the top end of the sleeve 2. The shaft end of the lifting screw 3 is interference-fitted with a bearing and a shaft seal 74. The bearing and the shaft seal 74 are both interference-fitted in the shaft hole of the second connecting member 72. The bottom of one end of the driving member 6 is fixedly connected to the third connecting member 73. The output end of the driving member 6 is sleeved around the shaft end of the lifting screw 3 and driven by a keyway.

[0033] Furthermore, the first connector 71 has a plurality of positioning pins 75 distributed around its top circumference, and the second connector 72 and the third connector 73 are both provided with positioning holes 76 corresponding to the positioning pins 75 on their outer edges.

[0034] The first connector 71, the second connector 72, and the third connector 73 are stacked sequentially by sealing gaskets and are circumferentially locked together by the positioning pin 75 and the positioning hole 76.

[0035] It should be added that, such as Figure 4 As shown, the first connector 71, the second connector 72 and the third connector 73 are stacked from bottom to top. The sealing gasket and shaft seal 74 are used to improve the sealing performance of the sleeve 2 and prevent material from overflowing.

[0036] Specifically, shaft seal 74 is a prior art device used to prevent material leakage along the gap between the rotating shaft and the stationary component.

[0037] More specifically, the connecting assembly 7 also includes a buckle 77. The third connector 73 and the sleeve 2 have at least one pair of corresponding protrusions 78 and fixing parts 79 distributed around the top outer edge of the circumference. The buckle 77 is rotatably connected to the side of the fixing part 79. The buckle 77 has an eccentrically rotating ring 771 located below the pivot, and the ring 771 is tightly held with the protrusion 78.

[0038] It is worth mentioning that the method of the buckle 77 holding the protrusion 78 by the ring buckle 771 is the prior art. When the ring buckle 771 is placed on the protrusion 78, the rotating arm of the buckle 77 can drive the ring buckle 771 to hold the protrusion 78 by eccentrically pulling the ring buckle 771.

[0039] When the first connector 71 and the third connector 73 are subjected to force at both ends, they press against the second connector 72 and ensure sealing under the action of the sealing gasket. Furthermore, because the material is conveyed by the lifting screw 3, no large pressure is generated inside the sleeve 2, which ensures good sealing.

[0040] In general, the anti-accidental touch structure 8 includes a pair of oppositely arranged arc-shaped parts 81. The pair of arc-shaped parts 81 are covered by closing the outer periphery of the connecting component 7. The pair of arc-shaped parts 81 are provided with a first connecting part 82 and a second connecting part 83 on the upper and lower sides at both ends, respectively.

[0041] Furthermore, the outer wall of the second connector 72 has a third connecting portion 84, and a pair of first connecting portions 82 are disposed on the upper and lower sides of the third connecting portion 84. The pair of first connecting portions 82 and the third connecting portion 84 are hinged and rotated by a pin.

[0042] Finally, a pair of second connecting parts 83 are arranged in an alternating and concentric manner. A plug rod 85 is slidably connected to the bottom of one of the second connecting parts 83 by a spring. The free end of the plug rod 85 is inserted into the through hole of the other second connecting part 83.

[0043] In this embodiment, as Figure 5 As shown, under normal circumstances, the pair of first connecting parts 82 and the third connecting parts 84 are hinged and rotated by a pin, so that the pair of arc-shaped parts 81 close and cover the periphery of the connecting assembly 7. Then, the insert rod 85 is inserted into the through hole of another second connecting part 83 under the support of the spring, so that the pair of arc-shaped parts 81 can be fixed.

[0044] Specifically, a finger or other tool can directly contact the insertion rod 85 through the through hole of the second connecting part 83. After the insertion rod 85 retracts and disengages from the through hole, the pair of arc-shaped parts 81 can be separated.

[0045] Furthermore, when the pair of curved sections 81 are closed, their inner walls can abut against the rotating arm of the buckle 77.

[0046] Working method: When working, open the cover door on the back of the temperature control machine body 1, first separate the sleeve 2 from the connecting pipe 5, and then disassemble the U-shaped clamp and the casting pipe. Then the sleeve 2, lifting screw 3 and driving component 6 can be taken out.

[0047] Then, a finger or other tool can directly contact the insertion rod 85 through the through hole of the second connecting part 83. After the insertion rod 85 retracts and disengages from the through hole, the pair of arc-shaped parts 81 can be separated.

[0048] Finally, rotate the rotating arm of the latch 77 in sequence. After the ring 771 disengages from the protrusion 78, first remove the drive component 6 and the third connector 73. Then, the second connector 72 and the lifting screw 3 can be removed together to clean the lifting screw 3 and the sleeve 2.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
