Description

Technical Field

[0001] This application relates to the field of crispy tube skin processing, and in particular to an automatic crispy tube skin stamping device. Background Technology

[0002] The crispy cone coating, commonly known as the crispy outer layer of a cone ice cream, has various names depending on its ingredients and manufacturing process, such as "crispy cone," "waffle cone," "crispy waffle cone," and "crispy cone." It's typically made from flour, sugar, and fat, baked to a crispy and delicious texture. In ice cream making, the cone coating not only serves as a container for the ice cream but is also a crucial component of the overall flavor. It adds extra layers of texture, making the ice cream more complex and flavorful in the mouth.

[0003] To meet the aesthetic requirements of ice cream cones, the flat cone shell material is typically cut and stretched after production to allow the final cone to hold the ice cream. In existing technology, this cutting and stretching process usually involves workers placing the cone shell material sequentially into a cutting mold and a stretching mold, then manually pressing the two molds to shape the cone, ultimately obtaining the desired open-top cone.

[0004] Regarding the existing technology mentioned above, the process of feeding the crispy cone skin into two molds sequentially and manually pressing it to form the skin is cumbersome and has low processing efficiency. Utility Model Content

[0005] In order to facilitate the processing and forming of crispy cone skins and improve the processing efficiency during the forming process, this application provides an automatic stamping device for crispy cone skins.

[0006] The automatic crispy tube skin punching device provided in this application adopts the following technical solution:

[0007] An automatic stamping device for crispy tube skin includes a frame, a placement seat, a stamping rod, a stamping drive assembly, a drawing rod, and a drawing drive assembly. The placement seat has a stamping forming groove on its top. The bottom of the stamping rod is directly opposite the stamping forming groove and is adapted to the shape of the stamping forming groove. The stamping drive assembly drives the stamping rod to move vertically. The bottom wall of the stamping forming groove has a drawing forming groove. The drawing rod passes vertically through and slides against the stamping rod. The drawing rod is directly opposite the drawing forming groove and is inserted into the drawing forming groove. The drawing drive assembly drives the drawing rod to move vertically.

[0008] By adopting the above technical solution, in the production and processing of crispy tube skin, the raw material is first placed on top of the placement seat. Then, the stamping drive assembly drives the stamping rod to move vertically, so that the stamping rod cooperates with the stamping forming groove to achieve the stamping and cutting of the crispy tube skin. Subsequently, the drawing drive assembly drives the drawing rod to move vertically, so that the drawing rod cooperates with the drawing forming groove to achieve the drawing of the stamped and cut crispy tube skin. During the cutting and drawing of the crispy tube skin, the stamping rod and the drawing rod are driven vertically by the stamping drive assembly and the drawing drive assembly, respectively. The operation is simple and helps to improve the processing efficiency of crispy tube skin forming.

[0009] Optionally, the stamping drive assembly includes a stamping drive component, a stamping rotating sleeve, and a stamping limiting component. The stamping rotating sleeve is rotatably mounted on the frame. The stamping drive component is used to drive the stamping rotating sleeve to rotate. The stamping rod passes through and is threaded into the stamping rotating sleeve. The stamping limiting component is used to restrict the rotation of the stamping rod around its own axis.

[0010] By adopting the above technical solution, when the stamping drive component drives the stamping rotating sleeve to rotate, the stamping rod moves vertically due to the threaded engagement with the stamping rotating sleeve and the limiting action of the stamping limiting component. The setting of the stamping rotating sleeve makes the movement of the stamping rod in the vertical direction convenient and fast.

[0011] Optionally, the stamping drive includes a stamping motor, a stamping worm gear is fixedly mounted on the output end of the stamping motor, and a stamping worm wheel is coaxially fixedly connected to the stamping rotating sleeve, with the stamping worm gear meshing with the stamping worm wheel.

[0012] By adopting the above technical solution, when the stamping motor drives the stamping worm to rotate, the stamping worm wheel, due to its meshing with the stamping worm, drives the stamping rotating sleeve to rotate together. The self-locking effect of the stamping worm wheel and the stamping worm helps to ensure the stability of the position of the stamping rotating sleeve after rotation.

[0013] Optionally, a limiting ring is fixedly installed on the stamping rod. When the limiting ring abuts against the top of the stamping worm gear, one end of the stamping rod is inserted into the stamping forming groove.

[0014] By adopting the above technical solution, the limiting ring plays a limiting role when the stamping rod moves in the vertical direction, so that the stamping rod can move stably to the position when stamping the brittle tube sheet material.

[0015] Optionally, the stamping limiting component includes a stamping fixing ring fixedly installed on the frame, the stamping rod passing through the stamping fixing ring, a stamping limiting part fixedly connected to the inner wall of the stamping fixing ring, the stamping rod having a stamping limiting groove extending along its own axis, and the stamping limiting part slidingly fitting within the stamping limiting groove.

[0016] By adopting the above technical solution, the combination of the stamping limiting part and the stamping limiting groove makes the structure of the stamping rod circumferentially limited around its own axis simple, convenient and practical.

[0017] Optionally, the drawing drive assembly includes a drawing telescopic cylinder, which is vertically mounted on the top of the stamping rod, and the drawing rod is fixedly mounted on the piston rod of the drawing telescopic cylinder.

[0018] By adopting the above technical solution, when the drawing telescopic cylinder drives its own piston rod to move, the drawing rod moves in the vertical direction. The design of the drawing telescopic cylinder makes the vertical movement of the drawing rod convenient and fast.

[0019] Optionally, a top-feeding assembly is provided in the deep drawing forming groove. The top-feeding assembly includes a top-feeding plate and a top-feeding spring. The top-feeding plate is slidably fitted into the deep drawing forming groove, and the top-feeding spring is installed in the deep drawing forming groove and applies an upward elastic force to the top-feeding plate.

[0020] By adopting the above technical solution, after the crispy tube skin is deep-drawn and the deep-drawing rod and the stamping rod are reset, the top plate pushes the formed crispy tube skin out of the deep-drawing groove under the elastic force of the top spring, which makes it easy to quickly remove the formed crispy tube skin from the placement seat.

[0021] Optionally, a top material guide rod is fixedly installed at the bottom of the top material plate, the top material guide rod passes through the placement seat and slides with the placement seat, and the top material spring is sleeved on the outside of the top material guide rod.

[0022] By adopting the above technical solution, the setting of the top material guide rod serves to limit the position of the top material plate and the top material spring. On the one hand, it facilitates the stability of the top material plate when it moves in the vertical direction, and on the other hand, it facilitates the top material spring to apply a stable elastic force to the top material plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During the cutting and deep drawing process of the crispy tube skin, the stamping rod and the deep drawing rod are driven vertically by the stamping drive assembly and the deep drawing drive assembly respectively. The operation is simple and helps to improve the processing efficiency of crispy tube skin forming.

[0025] 2. The limiting ring serves to limit the movement of the stamping rod in the vertical direction, so that the stamping rod can move stably to the position where it is stamping the brittle tube sheet material.

[0026] 3. After the crispy tube skin is deep-drawn and the deep-drawing rod and the stamping rod are reset, the top plate pushes the formed crispy tube skin out of the deep-drawing groove under the elastic force of the top spring, so that the formed crispy tube skin can be quickly removed from the placement seat.

[0041] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0042] Example 1.

[0043] This application discloses an automatic punching device for crispy tube sheets. (Refer to...) Figures 1 to 3 The automatic stamping device for crispy tube skin includes a first forming mechanism and a second forming mechanism. The first forming mechanism includes a base 01, a transmission device 02 fixed above the base 01, and a rotating frame 03 fixed above the transmission device 02. The rotating frame 03 is driven to rotate by the transmission device 02. The rotating frame 03 includes a lower die base 031, on which at least one lower die 032 is fixed. The rotating frame 03 also includes an upper die 033, which is located directly above the lower die 032 and cooperates with the lower die 032 for stamping. The upper die 033 is movably fixed on an upper die guide rail 04, and the movement can be sliding, rolling, or other methods. In this preferred embodiment, rolling is used. When the upper die 033 rolls along the upper die guide rail 04, the distance between it and the lower die base 031 changes within a certain range, that is, the upper die 033 continuously performs stamping movement relative to the lower die 032.

[0044] like Figure 4 The upper mold guide rail 04 shown is a undulating curve and is stationary relative to the base 01. When the rotating frame 03 rotates, it drives the lower mold base 031 and the upper mold 033 to rotate relative to the upper mold guide rail 04 and the base 01. The upper mold 033 rolls along the curve of the upper mold guide rail 04, so the upper mold 033 will move up and down while rotating, causing the distance between it and the lower mold base 031 to change within a certain range.

[0045] The rolling motion of the upper die 033 on the upper die guide rail 04 can be achieved in the following way: (Combined) Figure 5 As shown, one end of the upper mold 033 is the pressing end 0331, and the other end is shown below. Figure 6 As shown, a guide post 034 is connected to it; one end of the guide post 034 is connected to the upper mold 033, and the other end is provided with a roller 035, which can roll along the upper mold guide rail 04.

[0046] A schematic diagram of roller 035 rolling along upper mold guide rail 04 is shown below. Figure 7 As shown, roller 035 is suspended on upper mold guide rail 04. When upper mold 033 rises or falls, the force it experiences in the vertical direction changes, causing frictional variations and potentially leading to instability in its movement. Therefore, auxiliary roller 036 is provided on the side of guide post 034. Auxiliary roller 036 is located at the end of guide post 034 where roller 035 is located, close to roller 035, and its central axis is parallel to the central axis of roller 035. Upper mold guide rail 04 is equipped with corresponding double-layer guide rails 041 at the rising and falling positions. When roller 035 rolls along upper mold guide rail 04 to the rising or falling position, auxiliary roller 036 enters the double-layer guide rail 041 and rolls, making the rising and falling of upper mold 033 smoother.

[0047] In this preferred embodiment, a main shaft 037 is centrally located on the rotating frame 03. The main shaft 037 is connected to the transmission device 02, and the rotating frame 03 rotates around the main shaft 037. Several sets of upper dies 033 and lower dies 032 are arranged on the rotating frame 03, and these sets of upper dies 033 and lower dies 032 are rotationally symmetrical about the main shaft 037. The more sets of upper dies 033 and lower dies 032 there are, the higher the processing efficiency, but this also increases the diameter of the lower die holder 031, thus increasing the overall volume of the turntable device. Generally, 4-16 sets can be selected, that is, 4-16 lower dies 032 are fixed on the lower die holder, and a corresponding number of 4-16 upper dies 033 are arranged above them to cooperate with them. In this preferred embodiment, 8 sets are provided.

[0048] See the structure of the lower mold base 031. Figure 8 As shown, the main shaft 037 passes through the main shaft hole 0312 in the middle of the lower mold base 031. A keyway 0313 is also provided on the main shaft hole 0312 for driving the lower mold base 031 to rotate. Several through holes 0311 are provided around the main shaft hole 0312 for fixing and placing the lower mold 032. In this invention, there are 8 sets of upper molds 033 and lower molds 032, so the lower mold base 031 is provided with 8 through holes 0311.

[0049] Combination Figure 9The lower mold 032 shown is slightly smaller in size than the through hole 0311, allowing it to be placed within the through hole 0311 and fixed by the threaded hole 322 at the bottom of the lower mold 032 and the corresponding threaded hole on the lower mold base 031. A through hole is provided in the middle of the lower mold 032. (See attached image.) Figure 3 The enlarged view shows that the lower die 032 has a top die 0321 for ejecting the stamped item inside the through hole.

[0050] The top die 0321 is used to eject the stamped crispy tube skin. Before and during stamping, the bottom of the top die 0321 is flush with the bottom of the bottom die 032. After stamping, the top die 0321 rises to eject the crispy tube skin. The bottom die 032 can be of various shapes, such as square, oval, triangular, flower-shaped, or bowl-shaped cross-sections, to stamp out corresponding crispy tube skin shapes. Patterns or textures can also be set on the bottom die 032, such as... Figure 3 As shown, the lower die 032 is trumpet-shaped and engraved with patterned curves, which allows the stamped brittle belt to have corresponding shapes and patterns. Of course, a background pattern or pattern can also be set on the top die 0321.

[0051] The transmission device 02 includes a power unit 021 and a steering device 022, which are combined Figure 2 As shown, the rotation shaft of the power unit 021 is perpendicular to the main shaft 037 and can be driven by an electric motor. After being turned by the steering device 022, the output shaft of the steering device 022 is in the same direction as the main shaft 037, thereby transmitting power to the main shaft 037.

[0052] Because the guide post 034 is relatively long, in order to maintain coaxiality during the stamping process, a guide plate 038 is provided between the upper die guide rail 04 and the lower die base 031. Several through holes are provided on the circumference of the guide plate 038. The position and number of the through holes correspond to the position and number of the upper die 033, so that the upper die 033 passes through the guide plate 038 and can slide in the through holes to achieve the purpose of guidance.

[0053] To protect the upper mold guide rail 04, a guide rail cover is provided above the rotating frame 03, and the upper mold guide rail 04 is fixed underneath it. Simultaneously, a base 05 is provided below the rotating frame 03, and the lower mold base 031 is provided above the base 05 to protect the lower mold base 031. The crispy tube skin processed by the first forming mechanism can be held by a robotic arm and placed in the second forming mechanism for further processing. The arrangement of two forming mechanisms for processing the crispy tube skin helps to fully guarantee the forming quality of the crispy tube skin after stamping.

[0054] Reference Figure 10The second forming mechanism includes a frame 1, a placement seat 2, a stamping rod 3, a stamping drive assembly, a drawing rod 4, and a drawing drive assembly. The frame 1 includes a base plate 101, a fixing rod 102, and a mounting plate 103. The fixing rod 102 is vertically fixed to the top of the base plate 101, and the mounting plate 103 is horizontally fixed to the fixing rod 102.

[0055] Reference Figure 10 and Figure 11 The placement seat 2 is fixedly installed on the top of the base plate 101. The top of the placement seat 2 is provided with a stamping forming groove 5, and the bottom wall of the stamping forming groove 5 is provided with a drawing forming groove 6. After the crispy tube skin is processed and formed, it is located in the drawing forming groove 6. In order to facilitate the removal of the processed crispy tube skin from the drawing forming groove 6, a top material assembly is provided in the drawing forming groove 6.

[0056] Reference Figure 11 Specifically, the top material assembly includes a top material plate 7 and a top material spring 8. The top material plate 7 slides vertically within the deep drawing groove 6. The top material spring 8 is located at the bottom of the top material plate 7, with one end of the top material spring 8 fixedly connected to the bottom wall of the deep drawing groove 6 and the other end fixedly installed on the top material plate 7. The top material spring 8 applies an upward elastic force to the top material plate 7 so that the brittle tube skin is ejected from the deep drawing groove 6 through the top material plate 7 after stamping and deep drawing, thereby facilitating the removal of the formed brittle tube skin.

[0057] Continue to refer to Figure 11 To further ensure the stability of the top plate 7 when it ejects the formed brittle cylinder skin, a vertically set top guide rod 9 is fixedly installed at the bottom of the top plate 7. The top guide rod 9 passes through the placement seat 2 and slides with the placement seat 2 to limit the movement of the top plate 7. The top spring 8 is sleeved on the top guide rod 9 to ensure the stability of the position of the top spring 8 when it performs telescopic movement.

[0058] Reference Figure 10 and Figure 12 The stamping rod 3 includes a rod body 301 and a stamping head 302. The stamping head 302 is fixedly installed at the bottom of the rod body 301. The bottom of the stamping head 302 is directly opposite to the stamping forming groove 5 and is adapted to the shape of the stamping forming groove 5, so that the stamping of the brittle tube sheet material can be achieved through the cooperation of the stamping head 302 and the stamping forming groove 5. The stamping drive assembly includes a stamping drive component, a stamping rotating sleeve 11, and a stamping limiting component. The stamping drive component includes a stamping motor 10 fixedly installed on the top of the mounting plate 103. A stamping worm gear 12 is fixedly installed at the output end of the stamping motor 10. The stamping rotating sleeve 11 is rotatably installed on the top of the mounting plate 103 and a stamping worm wheel 13 is coaxially fixedly connected to the stamping coaxial sleeve. The stamping worm gear 12 meshes with the stamping worm wheel 13 so that when the stamping motor 10 drives the stamping worm gear 12 to rotate, the stamping worm wheel 13 drives the stamping rotating sleeve 11 to rotate together.

[0059] Continue to refer to Figure 10 and Figure 12 The rod body 301 of the stamping rod 3 is threaded through and threaded into the stamping rotating sleeve 11 in a vertical direction. The stamping limiting component includes a stamping fixing ring 14 fixedly installed at the bottom of the mounting plate 103. The rod body 301 passes through the stamping fixing ring 14 and slides in cooperation with the stamping fixing ring 14. A stamping limiting part 15 is fixedly connected to the inner wall of the stamping fixing ring 14. A stamping limiting groove 16 extending along its own axis is opened on the outer circumferential surface of the rod body 301. The stamping limiting part 15 slides in the stamping limiting groove 16 to limit the circumferential rotation of the stamping rod 3 around its own axis. Thus, when the stamping motor 10 drives the stamping rotating sleeve 11 to rotate, the stamping rod 3 moves in a vertical direction due to the threaded engagement with the stamping rotating sleeve 11 and the limiting effect of the stamping limiting part 15, which is convenient and stable.

[0060] Reference Figure 11 and Figure 12 To facilitate the stable movement of the stamping rod 3 to the position where it is stamping the brittle tube sheet material, a limiting ring 17 is fixedly installed on the outer circumferential surface of the rod body 301. When the bottom of the limiting ring 17 abuts against the top of the stamping worm gear 13, one end of the stamping rod 3 is inserted into the stamping forming groove 5 to limit the movement of the stamping rod 3 in the vertical direction.

[0061] Reference Figure 10 and Figure 12 The drawing rod 4 is vertically inserted and slidably engaged with the rod body 301 and the stamping head 302 of the stamping rod 3. The drawing drive assembly includes a drawing telescopic cylinder 18. In this embodiment, the drawing telescopic cylinder is specifically selected as a cylinder. The drawing telescopic cylinder 18 is vertically and fixedly installed on the top of the rod body 301 of the stamping rod 3. The drawing rod 4 is fixedly installed on the piston rod of the drawing telescopic cylinder 18 so as to drive the drawing rod 4 to move vertically through the drawing telescopic cylinder 18. The drawing rod 4 is directly opposite to the drawing forming groove 6 and is inserted into the drawing forming groove 6. When the drawing telescopic cylinder drives the drawing rod 4 to move vertically, the drawing rod 4 achieves the drawing treatment of the brittle cylinder skin after stamping and cutting through its engagement with the drawing forming groove 6.

[0062] The implementation principle of the automatic stamping device for crispy tube skin in Embodiment 1 of this application is as follows: During the processing and forming of crispy tube skin, the raw material is first processed and formed by the first forming mechanism. Then, the raw material formed by the first forming mechanism is placed on the top of the placement seat 2 by the robot arm. Subsequently, the stamping motor 10 drives the stamping rotating sleeve 11 to rotate, causing the stamping rod 3 to move in the vertical direction and achieve the stamping and cutting process of the crispy tube skin through cooperation with the stamping forming groove 5. Then, the drawing telescopic cylinder 18 drives the drawing rod 4 to move in the vertical direction, so that the drawing rod 4 achieves the drawing process of the stamped and cut crispy tube skin through cooperation with the drawing forming groove 6. During the cutting and drawing process of crispy tube skin, the stamping rod 3 and the drawing rod 4 are driven in the vertical direction by the stamping motor 10 and the drawing telescopic cylinder 18, respectively. The operation is simple and helps to improve the processing efficiency of crispy tube skin forming.

[0063] Example 2.

[0064] Reference Figure 10 An automatic stamping device for crispy tube skin includes a frame 1, a placement seat 2, a stamping rod 3, a stamping drive assembly, a drawing rod 4, and a drawing drive assembly. The frame 1 includes a base plate 101, a fixing rod 102, and a mounting plate 103. The fixing rod 102 is vertically fixed to the top of the base plate 101, and the mounting plate 103 is horizontally fixed to the fixing rod 102.

[0065] Reference Figure 10 and Figure 11 The placement seat 2 is fixedly installed on the top of the base plate 101. The top of the placement seat 2 is provided with a stamping forming groove 5, and the bottom wall of the stamping forming groove 5 is provided with a drawing forming groove 6. After the crispy tube skin is processed and formed, it is located in the drawing forming groove 6. In order to facilitate the removal of the processed crispy tube skin from the drawing forming groove 6, a top material assembly is provided in the drawing forming groove 6.

[0066] Reference Figure 11 Specifically, the top material assembly includes a top material plate 7 and a top material spring 8. The top material plate 7 slides vertically within the deep drawing groove 6. The top material spring 8 is located at the bottom of the top material plate 7, with one end of the top material spring 8 fixedly connected to the bottom wall of the deep drawing groove 6 and the other end fixedly installed on the top material plate 7. The top material spring 8 applies an upward elastic force to the top material plate 7 so that the brittle tube skin is ejected from the deep drawing groove 6 through the top material plate 7 after stamping and deep drawing, thereby facilitating the removal of the formed brittle tube skin.

[0067] Continue to refer to Figure 11To further ensure the stability of the top plate 7 when it ejects the formed brittle cylinder skin, a vertically set top guide rod 9 is fixedly installed at the bottom of the top plate 7. The top guide rod 9 passes through the placement seat 2 and slides with the placement seat 2 to limit the movement of the top plate 7. The top spring 8 is sleeved on the top guide rod 9 to ensure the stability of the position of the top spring 8 when it performs telescopic movement.

[0068] Reference Figure 10 and Figure 12 The stamping rod 3 includes a rod body 301 and a stamping head 302. The stamping head 302 is fixedly installed at the bottom of the rod body 301. The bottom of the stamping head 302 is directly opposite to the stamping forming groove 5 and is adapted to the shape of the stamping forming groove 5, so that the stamping of the brittle tube sheet material can be achieved through the cooperation of the stamping head 302 and the stamping forming groove 5. The stamping drive assembly includes a stamping drive component, a stamping rotating sleeve 11, and a stamping limiting component. The stamping drive component includes a stamping motor 10 fixedly installed on the top of the mounting plate 103. A stamping worm gear 12 is fixedly installed at the output end of the stamping motor 10. The stamping rotating sleeve 11 is rotatably installed on the top of the mounting plate 103 and a stamping worm wheel 13 is coaxially fixedly connected to the stamping coaxial sleeve. The stamping worm gear 12 meshes with the stamping worm wheel 13 so that when the stamping motor 10 drives the stamping worm gear 12 to rotate, the stamping worm wheel 13 drives the stamping rotating sleeve 11 to rotate together.

[0069] Continue to refer to Figure 10 and Figure 12 The rod body 301 of the stamping rod 3 is threaded through and threaded into the stamping rotating sleeve 11 in a vertical direction. The stamping limiting component includes a stamping fixing ring 14 fixedly installed at the bottom of the mounting plate 103. The rod body 301 passes through the stamping fixing ring 14 and slides in cooperation with the stamping fixing ring 14. A stamping limiting part 15 is fixedly connected to the inner wall of the stamping fixing ring 14. A stamping limiting groove 16 extending along its own axis is opened on the outer circumferential surface of the rod body 301. The stamping limiting part 15 slides in the stamping limiting groove 16 to limit the circumferential rotation of the stamping rod 3 around its own axis. Thus, when the stamping motor 10 drives the stamping rotating sleeve 11 to rotate, the stamping rod 3 moves in a vertical direction due to the threaded engagement with the stamping rotating sleeve 11 and the limiting effect of the stamping limiting part 15, which is convenient and stable.

[0070] Reference Figure 11 and Figure 12 To facilitate the stable movement of the stamping rod 3 to the position where it is stamping the brittle tube sheet material, a limiting ring 17 is fixedly installed on the outer circumferential surface of the rod body 301. When the bottom of the limiting ring 17 abuts against the top of the stamping worm gear 13, one end of the stamping rod 3 is inserted into the stamping forming groove 5 to limit the movement of the stamping rod 3 in the vertical direction.

[0071] Reference Figure 10 and Figure 12The drawing rod 4 is vertically inserted and slidably engaged with the rod body 301 and the stamping head 302 of the stamping rod 3. The drawing drive assembly includes a drawing telescopic cylinder 18. In this embodiment, the drawing telescopic cylinder is specifically selected as a cylinder. The drawing telescopic cylinder 18 is vertically and fixedly installed on the top of the rod body 301 of the stamping rod 3. The drawing rod 4 is fixedly installed on the piston rod of the drawing telescopic cylinder 18 so as to drive the drawing rod 4 to move vertically through the drawing telescopic cylinder 18.
