Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pitting machines, and in particular relates to a date pitting machine. Background Art
[0002] Red dates turn red when they mature and are often dried to make dried dates. They have a very high vitamin content and have the effect of nourishing yin and replenishing yang. As a tonic, red dates can also be used for medicinal purposes. In order to make red dates into food or medicine, they need to be processed through multiple steps, including using a pitting machine to remove the pits. The pitting machine is one of the key equipment in the fruit pulp production line of nuclear fruits. It separates the pulp and the core through physical squeezing, ensuring that the core is removed while obtaining the pulp to the greatest extent possible.
[0003] In the prior art, when red dates are put into the discharge hole, due to their own shape, the red dates often get stuck at the opening of the discharge hole and do not completely enter the discharge hole. In order to avoid this situation, the existing method is to use an extrusion column to squeeze the red dates stuck at the opening of the discharge hole into the discharge hole before punching the cores of the red dates, and then use a stamping part to remove the cores of the red dates. However, when using the above method, since the discharge hole is a through hole, when the extrusion column presses down the red dates, some smaller red dates may fall from the bottom opening of the discharge hole due to inertia, resulting in omission of core removal.

DETAILED DESCRIPTION
[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1
[0028] In the prior art, when red dates are put into the discharge hole, due to the limitation of their shape, the red dates often get stuck at the edge of the discharge hole and fail to enter completely. To avoid this situation, the current practice is to use an extrusion device to push the red dates stuck at the edge of the discharge hole into the discharge port before removing the pits of the red dates, and then use a punching device to complete the pitting work. However, in actual operation, since the discharge hole is a through-hole design, when the extrusion device presses the red dates downward, some smaller red dates may slide from the bottom of the discharge hole due to inertia, thereby causing the problem of incomplete pitting.
[0029] Therefore, in order to solve the above problem, the present invention discloses a jujube pitting machine, which can prevent the red dates from falling into the discharge hole 16 due to natural or inertial action. Figure 1-Figure 2, including a frame 1, a discharge tray 7, including a rotating disk 15, which is arranged on the frame 1 and can rotate, and the rotating disk 15 is provided with a discharge hole 16 for placing red dates, a pressing mechanism 9, including a lower pressing plate, which is arranged in parallel above the rotating disk 15, and the side of the lower pressing plate facing the rotating disk 15 is sequentially provided with an extrusion column, a punch and a push rod distributed along the rotation direction of the rotating disk 15, a feeding mechanism, including a jujube core channel 10 and a jujube meat channel 11, which are arranged at the bottom of the discharge tray 7, wherein the jujube core channel 10 is parallel to the punch up and down, and the jujube meat channel 11 is parallel to the push rod up and down, and the discharge tray 7 also includes a tray 12 stacked at the bottom of the rotating disk 15, and the tray 12 includes a solid layer 13 and a hollow layer 14, wherein the hollow layer 14 is located between the feeding mechanism, the punch and the push rod;
[0030] In this embodiment, when the rotating disk 15 rotates the discharge hole 16 containing red dates to below the pressing mechanism 9, the pressing plate begins to sink and drives the squeezing column to move toward the discharge hole 16. Then, the squeezing column can press the red dates stuck at the top opening of the discharge hole 16 into the discharge hole 16. At this time, the solid layer 13 can be attached to the bottom opening of the discharge hole 16 by the arrangement of the tray 12, so as to prevent the red dates from falling from the discharge hole 16.
[0031] Then, when the red dates are pressed into the discharge hole 16, the lower pressing plate is lifted, and the rotating disk 15 continues to rotate toward the punch. At this time, the lower pressing plate can sink again, so that the punch can be pressed into the discharge hole 16 to perform the core removal operation. At the same time, the punched-out date pits will fall through the hollow layer 14 into the date pit channel 10 for discharge. Then the lower pressing plate continues to lift, and the rotating disk 15 continues to rotate toward the pushing rod. At this time, the lower pressing plate sinks again, so that the pushing rod can push the date meat with the date pits removed in the discharge hole 16 out of the discharge hole 16. The date meat will fall into the date meat channel 11 for collection;
[0032] It can be understood that the extrusion column, the punch and the push rod are all arranged on the same lower pressing plate, so that when the lower pressing plate is pressed down, the extrusion, the core removal and the falling date operations can be performed simultaneously, thereby improving the working efficiency of the equipment;
[0033] It should be noted that the tray 12 is fixed to the top of the frame 1 , and the tray 12 is connected to the rotating disk 15 via a rotating shaft, which can be driven by a motor so that the rotating disk 15 can rotate above the tray 12 .
[0034] In this embodiment, in order to enable the lower pressing plate to perform reciprocating lifting and lowering motion in the vertical direction, a gantry 8 is provided on the frame 1, and a lifting mechanism is provided between the gantry 8 and the lower pressing plate. The gantry 8 can improve the stability of the lower pressing plate during lifting. The lifting mechanism includes a hydraulic cylinder or a pneumatic cylinder, and the vertical lifting and lowering motion of the lower pressing plate is achieved by controlling the extension and contraction of the hydraulic cylinder or the cylinder.
[0035] The extension and retraction of the hydraulic cylinder or pneumatic cylinder is controlled by the upper computer to ensure the precise position of the lower pressure plate during the squeezing, pitting and falling operations.
[0036] Example 2
[0037] On the basis of embodiment 1, in the prior art, when the punch is performing the punching and pitting operation on the red dates, some smaller red dates are prone to deviation and shaking, resulting in the inability to accurately find the cutting position when pitting, causing pitting failure. At the same time, these smaller red dates may also be directly ejected from the discharge hole 16 and fall into the date pit channel 10 due to the impact of the punch, causing waste. Therefore, in order to solve the above problem, refer to Figure 3 The present invention further includes a clamping ring 17 for clamping red dates. Specifically, a clamping ring 17 for clamping red dates is provided on the inner wall of the discharge hole 16, and a telescopic member 18 is provided between the clamping ring 17 and the inner wall of the discharge hole 16;
[0038] In this embodiment, by setting the clamping ring 17, when the red dates enter the discharge hole 16, the clamping ring 17 can clamp the red dates under the push of the telescopic member 18, thereby avoiding the shaking of some smaller red dates when the core is punched, and improving the stability of the red dates when the core is removed. At the same time, by clamping the clamping ring 17, the red dates can be stabilized in the center of the discharge hole 16, so that the punch can easily find the cutting position when punching;
[0039] The telescopic member 18 includes a telescopic cylinder and a telescopic rod. A sensor component for controlling the telescopic member 18 is provided in the discharge hole 16. The sensor component includes a contact sensor or an infrared sensor. When the red dates enter the designated position in the discharge hole 16, the sensor component can activate the telescopic member 18, so that the telescopic member 18 can drive the clamping ring 17 to clamp the red dates. When the red dates leave the designated position, the telescopic member 18 is closed and the clamping ring 17 is reset.
[0040] It should be noted that, in the initial state, the clamping ring 17 is movably arranged inside the inner wall of the discharge hole 16, that is, the clamping ring 17 and the inner wall of the discharge hole 16 are at the same horizontal height. At the same time, an elastic member, such as a spring, is provided between the telescopic rod and the clamping ring 17, so that the clamping ring 17 can clamp the red dates and also contract to both sides due to the squeezing of the red dates when the pushing rod pushes the red dates downward, so that the red dates can fall smoothly from the discharge hole 16;
[0041] Exemplarily, the clamp ring 17 is arranged at the middle and lower part of the depth of the discharge hole 16. With this arrangement, when the red dates are pushed into the discharge hole 16 by the squeezing column and move to the middle and lower part of the depth of the discharge hole 16, the sensor component will open the telescopic part 18, so that the clamp ring 17 can clamp the red dates, stabilizing the red dates and preventing them from falling.
[0042] Example 3
[0043] On the basis of Example 1, in order to improve the efficiency of putting red dates, refer to Figure 1 The present invention further includes a feeding box 2. Specifically, the frame 1 is further provided with a feeding box 2 for feeding red dates, wherein the feeding box 2 is arranged above the discharge tray 7 away from the pressing mechanism 9;
[0044] In this embodiment, the loading box 2 includes a loading port 3, a delivery port 4 and a first brush 5, wherein the input end of the delivery port 4 is connected to the loading port 3, and the output end of the delivery port 4 is arranged above the rotating disk 15, and the first brush 5 is arranged at the output end of the delivery port 4, wherein the loading port 3 is arranged at an inclined angle, and the delivery port 4 is arranged at the lowest port of the loading port 3. When the user delivers red dates, multiple red dates can be poured into the loading port 3 at one time, and then the red dates can fall from the delivery port 4 along the inclined direction of the loading port 3 onto the rotating disk 15. In this process, the first brush 5 can rotate in a circle to put the fallen red dates into the discharge hole 16;
[0045] A rotating shaft is provided in the feeding box 2 for enabling the first brush 5 to rotate in a circular motion. At the same time, the first brush 5 is arranged in a cross-shaped structure. Through the cross-shaped arrangement, the red dates falling from the feeding port 4 will be received by the first brush 5, and then fall onto the rotating disk 15 in batches as the first brush 5 rotates, which helps to prevent excessive red dates from accumulating on the rotating disk 15.
[0046] In addition, by adjusting the rotation speed of the first brush 5, the falling speed of the red dates can be controlled;
[0047] Furthermore, a second brush 6 is provided between the feeding box 2 and the pressing mechanism 9, wherein the second brush 6 is cylindrical and horizontally attached to the top of the rotating disk 15. When the red dates fall onto the rotating disk 15 through the feeding port 4, the red dates that have not yet entered the discharge hole 16 will come into contact with the second brush 6 as the rotating disk 15 rotates. Since the second brush 6 is attached to the top of the rotating disk 15, the red dates that have not yet entered the discharge hole 16 will be blocked by the second brush 6, while the red dates that have entered the discharge hole 16 can pass under the second brush 6.
[0048] Among them, the second brush 6 also rotates in a circle through another rotating shaft in the feeding box 2, and the second brush 6 rotates toward the feeding box 2. When the second brush 6 rotates, it will move the blocked red dates so that these red dates can be moved into the discharge hole 6;
[0049] In addition, since the second brush 6 is cylindrical, it can also press the red dates when it rotates and moves the red dates, so that the red dates can be pressed into the discharge hole 16.
[0050] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0051] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
