Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of fruit processing equipment, and in particular relates to a fruit processing and cutting machine. Background Art
[0002] Fresh fruits have a relatively short shelf life, but the shelf life of processed fruits is greatly extended. Larger fruits are not suitable for processing into preserved fruits as a whole, as they will dehydrate more slowly and are inconvenient to eat. Therefore, fruits that are nearly spherical, such as apples, peaches, kiwis, plums, and dragon fruits, usually need to be sliced into slices with a thickness of about 5 mm, which is helpful for dehydration and making preserved fruits. At the same time, they can also be freeze-dried at low temperature to make dried fruit slices, which not only does not affect the nutritional content, but also prolongs the shelf life and is convenient for long-term storage.
[0003] The existing fruit slicing device pushes the fruit to a discharge port through a propulsion device, and a knife group is arranged at the discharge port. The knife group reciprocates at the discharge port to cut the fruit part removed from the discharge port, and the fruit is slowly pushed out of the discharge port by the propulsion device. The propulsion speed is coordinated with the reciprocating movement frequency of the knife group to achieve the goal of just cutting the fruit into slices of a specified thickness. This method has neat incisions in the early stage of cutting, but when cutting to the tail of the fruit, since the fruit is a sphere, the remaining part of the tail is difficult to bear force at the discharge port position, and the discharge port has insufficient fixing force on the arc section of the fruit tail, resulting in the tail end of the fruit being discharged directly from the discharge port without being cut, resulting in the problem of uneven local thickness.
[0004] Therefore, the present invention provides a fruit cutting device, which pushes the fruit through a spiral pushing roller. During the pushing stage, the fruit passes through a cutting point. The tail end of the pushing roller is a discharge port, and the cut fruit slices are uniformly discharged, thereby avoiding the problem of uneven cutting due to insufficient fixing force at the tail end of the fruit. Summary of the invention
[0005] The object of the present invention is to provide a fruit processing and slitting machine, which pushes fruit through a spiral pushing roller. During the pushing stage, the fruit passes through a cutting point. The tail end of the pushing roller is a discharge port, and the cut fruit slices are uniformly discharged, thereby avoiding the problem of uneven slitting caused by insufficient fixing force at the tail end of the fruit.
[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: A fruit processing and slitting machine comprises a conveying cylinder, wherein the conveying cylinder is a horizontally arranged cylinder structure, wherein the upper side of one end of the conveying cylinder is an opening side for a feeding port, and the lower side of the other end is an opening side for a discharging port; A push roller is sleeved inside the conveying cylinder, a roller shaft is fixed at the axis position of the push roller, a spiral groove is opened on the side wall of the push roller, and an annular groove is opened on the side of the push roller close to the discharge port. The annular groove is arranged around the circumference of the push roller, and the depth of the annular groove is greater than the depth of the spiral groove; A first motor is installed on the upper side of the conveying cylinder, and a knife group is installed on the output end of the first motor. The knife group corresponds to the annular groove, and the annular motion trajectory extends into the annular groove. A notch for the knife group to move is opened on the upper side of the conveying cylinder.
[0007] Furthermore, the conveying cylinder has end covers on both sides, and the end covers have an axial hole for the roller shaft to pass through and rotate. The roller shaft is installed with a first pulley at the end passing through the axial hole. A second motor is installed next to the conveying cylinder, and a second pulley is installed at the output end of the second motor. The first pulley and the second pulley are transmitted by a belt.
[0008] A support frame is installed at the bottom of the conveying cylinder for raising the discharge port. A support plate is provided at the bottom of the support frame, and a receiving tray is installed at a position of the support plate corresponding to the discharge port.
[0009] Furthermore, the knife set includes two centrosymmetrical blades, and the corresponding cutting edges of the blades are arc-shaped.
[0010] A positioning frame is installed at a position corresponding to the end of the shaft of the first motor. The positioning frame is fixed to the upper side of the conveying cylinder. An axial hole for the shaft of the first motor to pass through is opened on the upper side of the positioning frame.

[0012] Furthermore, a feeding bin is provided at a position of the conveying cylinder corresponding to the feeding port, and an inclined feeding plate is installed inside the feeding bin.
[0013] The present invention has the following beneficial effects: the push roller is closely attached to the inside of the conveying cylinder, the front end of the push roller is located at the lower side of the feeding port, and is used to put the fruit in and directly clamp it into the spiral groove. With the rotation of the push roller, the spiral groove has the function of pushing the material forward. The fruit is approximately spherical and rolls forward in the spiral groove. When passing through the annular groove, the knife group can cut the fruit. With the slow movement of the push roller, the fruit is cut into equidistant thicknesses. Due to the clamping effect of the side wall of the spiral groove, the tail end of the fruit is also completely cut, and the cut fruit slices are discharged from the outlet at the tail end of the spiral groove in sequence.

DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] like Figure 1-2 As shown: A fruit processing and slitting machine comprises a conveying cylinder 1, which is a horizontally arranged cylinder structure, wherein the upper side of one end of the conveying cylinder 1 is an opening side for a feeding port, and the lower side of the other end is an opening side for a discharging port; A push roller 2 is sleeved inside the conveying cylinder 1, and a roller shaft 5 is fixed at the axis position of the push roller 2. A spiral groove 21 is opened on the side wall of the push roller 2, and an annular groove 22 is opened on the side of the push roller 2 close to the discharge port. The annular groove 22 is arranged around the circumference of the push roller 2, and the depth of the annular groove 22 is greater than the depth of the spiral groove 21. A first motor 3 is installed on the upper side of the conveying cylinder 1, and a knife group is installed on the output end of the first motor 3. The knife group corresponds to the annular groove 22, and the annular motion trajectory extends into the annular groove 22. A notch 11 for the knife group to move is opened on the upper side of the conveying cylinder 1.
[0020] The push roller is tightly attached to the inside of the conveyor cylinder. The front end of the push roller is located at the lower side of the feeding port. It is used to put the fruit in and directly clamp it into the spiral groove. With the rotation of the push roller, the spiral groove has the function of pushing the material forward. The fruit is approximately spherical and rolls forward in the spiral groove. When passing through the annular groove, the knife group can cut the fruit. With the slow movement of the push roller, the fruit is cut into equal thicknesses. Due to the clamping effect of the side wall of the spiral groove, the tail end of the fruit will also be completely cut, and the cut fruit slices will be discharged from the outlet at the tail end of the spiral groove in sequence.
[0021] like Figure 1-2As shown: both sides of the conveying cylinder 1 are end covers, and the end covers have shaft holes for the roller shaft 5 to pass through and rotate. The roller shaft 5 is installed with a first pulley 51 at the end passing through the shaft hole. A second motor 4 is installed beside the conveying cylinder 1. A second pulley 41 is installed at the output end of the second motor 4. The first pulley 51 and the second pulley 41 are driven by a belt 42. By changing the tooth pitch between the first pulley and the second pulley, the torque is increased and the rotation speed of the push roller is slowed down.
[0022] A support frame 12 is installed at the bottom of the conveying cylinder 1 for raising the discharge port. A support plate 13 is provided at the bottom of the support frame 12. A receiving tray 7 is installed at the position of the support plate 13 corresponding to the discharge port.
[0023] like Figure 1 As shown: the knife group includes two centrosymmetrical blades 31, and the blades 31 have arc-shaped blade edges. The arc-shaped blade edges are helpful for cutting fruits. A positioning frame 14 is installed at the end of the shaft corresponding to the first motor 3, and the positioning frame 14 is fixed to the upper side of the conveying cylinder 1. The upper side of the positioning frame 14 is provided with an axial hole for the shaft of the first motor 3 to pass through. The stability of the knife group driven by the first motor to rotate is improved.
[0024] like Figure 2 As shown: the bottom of the spiral groove 21 is an arc-shaped cross-section, and the side wall of the spiral groove 21 is a guide wall 23. The bottom of the spiral groove is an arc-shaped structure for abutting against the side wall of the fruit, and the guide plate is an extension of the corresponding end of the bottom arc-shaped part, which is used to increase the depth of the spiral groove and accommodate the complete fruit.
[0025] The position of the conveying cylinder 1 corresponding to the feeding port is provided with a feeding bin 6, and an inclined feeding plate 61 is installed inside the feeding bin 6. The feeding plate is used for guiding, and the fruits are automatically arranged in a row when they are guided to the feeding port, so that the fruits can enter the spiral groove individually.
[0026] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
