Goat milk is rich in protein, minerals and vitamins, and the fat globules in goat milk are small, which is easy for the human body to digest and absorb. When processing pet snacks containing goat milk powder in the raw materials, extrusion equipment is required to extrude the raw materials into shape.

[0003] For example, the utility model with application number CN202211655502.9 discloses an extrusion mechanism that can adjust the compactness of pet snacks. The pet snacks of this utility model can be extruded and formed in one go, which reduces the process and cost, improves the degree of automation, and avoids the influence of other factors in the material transfer process; at the same time, snacks with different compactness can be formed as needed, which improves the applicability of this application. However, after long-term use, the ejection plate is prone to cause the spring to slowly lose its elasticity, making it difficult to remove the formed snacks.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an extrusion mechanism with the effect of adjusting the molding firmness of goat milk powder is proposed. Utility Model Content

[0008] Furthermore, a movable seat is arranged on the right side of the screw nut, and a transmission shaft 1 is arranged in a bearing at the middle opening of the movable seat, and a worm gear 1 is sleeved on the outside of the transmission shaft 1.

[0009] Furthermore, a squeezing roller is installed at the rear end of the transmission shaft 1, and the squeezing roller includes a roller body 1 and a driving motor 1, and a driving motor 1 is installed at the rear end inside the roller body 1.

[0010] Furthermore, the extrusion roller also includes a sliding pin, a sliding frame and a guide roller, and the output shaft of the driving motor is connected to the sliding pin, the guide roller is rotatably arranged inside the roller body, and a sliding frame is arranged between the guide rollers.

[0011] Furthermore, the sliding frame 1 and the sliding frame 2 are located on the same vertical central axis, and four guide rollers 1 and 2 are provided respectively.

[0016] 2. After the roller body 2 with formed snacks installed in the top forming groove of the utility model rotates clockwise, the sliding pin 2 is driven to rotate by the driving motor 2, and the sliding pin 2 drives the sliding frame 2 to move vertically downward between the guide rollers 2, so that the formed snacks can be pushed to the collection box. In this way, the connecting rod motion mechanism is used instead of the spring, which overcomes the disadvantage that the spring loses its elasticity due to long-term use, making it difficult to take out the formed snacks.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] The specific operation is as follows: by turning the hand wheel 2 to provide a rotational force for the screw 3, the screw nut 4 drives the movable seat 5 to move longitudinally along the outside of the screw 3, thereby adjusting the distance between the extrusion roller 7 and the discharge roller 11 to meet the adjustment requirements for the compactness of the extruded snacks. Since the transmission shaft 6 and the bearing at the middle opening of the movable seat 5 are interference fit, the worm gear 8 and the worm 1403 are kept in meshing, so that the extrusion roller 7 and the discharge roller 11 with opposite rotation directions are used to extrude the raw materials into shape.

[0024] like Figures 1 to 3 As shown, the rear end of the transmission shaft 6 is equipped with an extrusion roller 7, and the extrusion roller 7 includes a roller body 1101 and a driving motor 1102. The rear end of the roller body 1101 is equipped with a driving motor 1102. The extrusion roller 7 also includes a sliding pin 1103, a sliding frame 1104 and a guide roller 1105. The output shaft of the driving motor 1102 is connected with the sliding pin 1103. The guide roller 1105 is rotatably arranged inside the roller body 1101, and a sliding frame 1104 is arranged between the guide rollers 1105. The discharging roller 1101 includes a roller body 1101, a driving motor 1102, and a guide roller 1105. Machine 2 1102, sliding pin 2 1103, sliding frame 2 1104 and guide roller 2 1105, and the inner rear end of roller body 2 1101 is installed with driving motor 2 1102, the output shaft of driving motor 2 1102 is connected with sliding pin 2 1103, and sliding frame 2 1104 is arranged outside sliding pin 2 1103, guide roller 2 1105 is arranged on both sides of sliding frame 2 1104, sliding frame 1 704 and sliding frame 2 1104 are located on the same vertical central axis, and guide roller 1 705 and guide roller 2 1105 are each arranged with four.

[0025] The specific operation is as follows: after the roller body 1101 containing the formed snacks in the top forming groove is rotated 180 degrees clockwise, the sliding pin 1103 is driven to rotate by the driving motor 1102, and the sliding frame 1104 is driven by the sliding pin 1103 to move vertically downward between the guide rollers 1105, so that the formed snacks can be pushed to the collection box 13. In this way, the connecting rod motion mechanism is used instead of the spring to overcome the disadvantage that the spring loses its elasticity due to long-term use, which makes it difficult to take out the formed snacks.

[0026] In summary, when the extrusion mechanism with the effect of adjusting the compactness of goat milk powder is used, first adjust the distance between the extrusion roller 7 and the discharge roller 11 to achieve the effect of adjusting the compactness of the extruded snacks, that is, turn the hand wheel 2 to make the screw nut 4 move longitudinally along the screw 3. As the distance between the movable seat 5 and the fixed seat 9 increases or decreases, the external worm wheel 8 of the transmission shaft 6 that is interference-fitted with the bearing at the middle opening of the movable seat 5 will always be close to the worm 1403, thereby satisfying the conditions that the servo motor 1402 drives the worm 1403 to rotate, and the worm 1403 respectively drives the worm wheel 18 and the worm wheel 2 12 to drive the transmission shaft 16 and the transmission shaft 2 10 to rotate;

[0027] Since the top and bottom of the roller body 1 701 and the roller body 2 1101 are both provided with forming grooves, after the raw material is fed between the roller body 1 701 and the roller body 2 1101, the driving motor 1 702 is controlled to drive the sliding pin 1 703 to rotate, and the sliding frame 1 704 is driven by the sliding pin 1 703 to move vertically downward between the guide rollers 1 705, so that the raw material in the forming groove on the top of the roller body 2 1101 can be pressed tightly;

[0028] Subsequently, the driving motor 1 702 continues to drive the sliding pin 1 703 to rotate, and the sliding pin 1 703 drives the sliding frame 1 704 to move vertically upward between the guide roller 1 705, so that the roller body 2 1101 is capable of rotating. At this time, the roller body 2 1101 rotates 180 degrees clockwise under the drive of the servo motor 1402, and the driving motor 2 1102 drives the sliding pin 2 1103 to rotate, and the sliding pin 2 1103 drives the sliding frame 2 1104 to move vertically downward between the guide roller 2 1105, which can push the formed snacks to the collection box 13. In this way, the connecting rod motion mechanism is used instead of the spring to overcome the disadvantage that the spring loses its elasticity due to long-term use, which makes it difficult to take out the formed snacks.
