Description

Technical Field

[0001] This application relates to the field of extruder technology, and for example to a rotary cutting device for an extruder. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] Extruders, as a type of food processing equipment, are widely popular because they can efficiently transform various grains and cereals into crispy and nutritious twisted dough sticks. These machines are typically operated on-site at street stalls or food processing facilities, attracting a large number of consumers with their freshly made, healthy, and delicious characteristics. The continuous operation of extruders necessitates the use of a highly efficient automatic rotary cutting device to produce segmented twisted dough sticks.

[0004] However, current puffing machine veneer devices generally rely on custom-made blades from manufacturers. While these blades meet cutting requirements, their customized design leads to high costs. More importantly, because puffing machines operate under high loads for extended periods, the blades wear out quickly, making replacement or periodic sharpening a regular occurrence. While commercially available, universal blades are inexpensive and readily available, their incompatibility with size or mounting interfaces prevents direct application to existing puffing machine veneer devices. Therefore, developing an automatic puffing machine veneer device that is compatible with universal blades, easy to replace, and effectively reduces maintenance costs has become a pressing technical challenge.

[0042] Combination Figure 1-5 As shown, this embodiment of the present disclosure provides a rotary cutting device for an extruder, including: a support frame, a motor 17, a connecting seat 21, a blade holder 18, and a clamping block 183;

[0043] The support frame is installed on the extruder 11 or on the ground;

[0044] Motor 17 is fixedly mounted on the support frame. Motor 17 is a high-torque, low-noise DC brushless motor 17, and its speed is controlled by a frequency converter. Alternatively, a stepper motor 17 or a servo motor 17 can be used. It can work according to the set running interval and speed. The interval can be set according to time or according to the length of the twist. It rotates once each time. A higher speed is better and the cut is flat.

[0045] The connecting seat 21 is connected to the output shaft of the motor 17; the connecting seat 21 is a flange structure that is directly connected to the output shaft of the motor 17.

[0046] The tool holder 18 is connected to the connecting seat 21; the middle part of the tool holder 18 is connected to the connecting seat 21 by screws.

[0047] The positioning groove 182 is provided on the tool holder 18 and can accommodate the blade 19;

[0048] The clamping block 183 is shaped to fit the positioning groove 182 and is connected to the positioning groove 182 by the positioning screw 184. It cooperates with the positioning groove 182 to clamp the blade 19.

[0049] The rotary cutting device for the extruder 11 provided in this disclosure uses a universal blade 19, eliminating the need for manufacturer-made blades 19 and significantly reducing the user's blade 19 procurement costs. The maintenance process is simplified through the cooperation of the positioning groove 182 and the clamping block 183. The positioning groove 182 and the clamping block 183 fully consider the size and installation requirements of the universal blade 19, ensuring that blades of various standard specifications can be securely clamped. This solves the problem of universal blades 19 being unusable due to size or interface incompatibility in the market, enhancing the versatility and flexibility of the device.

[0050] In some embodiments, the support frame includes: a connecting arm 12 and a mounting plate 16;

[0051] The connecting arm 12 is a metal rod, one end of which is connected to the extruder 11; the connecting arm 12 can also be connected to a tripod and fixedly mounted on the ground. The tripod can also have a height extension function. The tripod is a conventional technical means in this field and is not shown in the attached drawings.

[0052] Mounting plate 16 is a metal plate or a thick plastic plate, and its rear is connected to connecting arm 12 by brackets and screws.

[0053] The motor 17 has mounting holes on the mounting plate 16 for fixed mounting.

[0054] In some embodiments, the rotary cutting device for the extruder 11 further includes: a guide groove 13 and a connecting frame 131;

[0055] The guide groove 13 is located at the outlet of the extruder 11 at one end and connected to the mounting plate 16 at the other end, and is located in the cutting area of ​​the blade 19. The guide groove 13 is a square groove or an arc groove, which is made by bending metal plate, and the length is selected according to the characteristics of the twist.

[0056] The connecting bracket 131 is connected to the guide groove 13 at one end and to the connecting arm 12 at the other end. The connecting bracket 131 is an L-shaped bracket and is connected to the guide groove 13 by screws / welding.

[0057] In some embodiments, the mounting plate 16 includes: a rotary notch 161

[0058] The rotary cut 161 is a square notch located on the upper left side of the mounting plate 16. An arc-shaped groove is provided on the lower side of the square notch, which mates with the guide groove 13, providing support for the guide groove 13. The guide groove 13 extends to the blade 19. The rotary cut 161 greatly facilitates the placement of the twist at the cutting point of the blade 19. A magnet 15 is provided on one side of the rotary cut 161, and the magnet 15 is connected to the mounting plate 16 by adhesive or screws.

The inner wall of the positioning groove 182 on the opposite side of the positioning step 185 is an inclined surface. The clamping block 183 has a right-angled trapezoidal structure and an elongated hole. The bolt passes through the elongated hole and is threaded into the positioning groove 182. When the bolt tightens the clamping block 183, the inclined surface of the positioning groove 182 engages with the inclined surface of the clamping block 183, causing the clamping block 183 to move in the direction of the plane where the positioning step 185 is located, thereby achieving the tightening of the blade 19.

[0060] In some embodiments, a protective cover 14 is hinged to the front side of the mounting plate 16. The right side of the protective cover 14 is hinged to the mounting plate 16, and the upper left side of the protective cover 14 has a notch with the same shape as the spiral cut 161 on the mounting plate 16. The protective cover 14 has a handle 141, and a magnet 15 is provided on the notch of the protective cover 14.

[0061] In some embodiments, a balance block 181 is connected to one end of the tool holder 18, and the balance block 181 is disposed opposite to the positioning groove 182. The balance block 181 balances the weight on both sides of the tool holder 18 and reduces vibration. The tool holder 18 and the clamping block 183 are made of plate and are machined using CNC machining.
