Description

Technical Field

[0001] This utility model relates to the field of corn end removal devices, and more particularly to a movable fastening mechanism for corn end removal devices. Background Technology

[0002] In the processing of fresh corn, to ensure product quality, it is necessary to precisely remove the small and immature kernels from the top of the corn cob. Traditional processing methods typically involve manual removal with a knife. This method is not only labor-intensive and inefficient, but also poses significant safety hazards, easily causing hand injuries to operators.

[0003] To optimize processing and improve production safety, modern processing technology has developed specialized equipment for cutting the ends of fresh corn. This equipment can efficiently complete the standardized removal of the corn head. For example, Chinese patent application number CN202322869773.0 describes a corn cutting device, including a processing table. The upper surface of the processing table is equipped with a limiting mechanism, and a cutting assembly is also mounted on the upper surface. The cutting assembly includes two symmetrically positioned fixed frames. Two pneumatic telescopic rods are fixedly connected to the surfaces of the fixed frames. The telescopic ends of the pneumatic telescopic rods extend below the fixed frames and are fixedly connected to a movable seat. A cutting blade is fixedly mounted on the lower surface of the movable seat. By providing a horizontally movable limiting frame on the surface of the processing table, the limiting frame can drive the corn to move horizontally back and forth, thereby causing the head and tail of the corn to sequentially enter below the cutting assembly, whereby the cutting assembly cuts the head and tail of the corn separately.

[0004] The existing technology similar to the above patent has the following problems: the limiting frame does not secure the corn, so only one end of the corn is subjected to force during cutting, which can easily cause the corn to lift up and affect the cutting quality; when the corn is moved laterally by the limiting frame, the corn can easily fall out of the limiting frame or move, causing cutting deviation.

[0005] Therefore, there is an urgent need for a movable fastening mechanism for corn end removal devices, which can fasten the corn during adjustment of its position and during the cutting process, thereby improving cutting quality and ensuring production efficiency. Utility Model Content

[0006] To address the problem of the lack of securing mechanisms during the cutting and lateral movement of corn in existing technologies, this utility model proposes a movable securing mechanism for a corn end removal device, the technical solution of which is as follows:

[0007] A movable fastening mechanism for a corn end removal device, the corn end removal device includes a horizontally arranged machine platform, a guide rail arranged on the machine platform, and a cutting mechanism mounted above the guide rail. The movable fastening mechanism is configured in conjunction with the guide rail and the cutting mechanism, and includes a corn placement platform slidably arranged on the guide rail, and a driving device is provided on one side of the corn placement platform to move the corn placement platform to a designated position.

[0008] The top surface of the corn placement platform has several parallel placement slots perpendicular to the length of the guide rail, and the axis of the placement slots is parallel to the length of the guide rail.

[0009] A fixing mechanism is provided on the corn placement platform to fix the corn. The fixing mechanism includes rotating units on both sides of the corn placement platform. A pressing rod is vertically installed on the rotating unit. The axis of the pressing rod is perpendicular to the length direction of the guide rail. The rotating unit can make the pressing rod press down and rotate on one side of the corn placement platform perpendicular to the length direction of the guide rail.

[0010] The placement slots are equipped with sensors. When corn is placed in several slots, the rotating unit is activated, which drives the clamping rod to rotate and clamp the corn. After the corn is removed, the rotating unit drives the clamping rod to lift.

[0011] Furthermore, the placement groove is a through groove opened on the corn placement platform, the inner wall of the through groove is a concave arc surface, and the inner wall is provided with anti-slip texture.

[0012] Furthermore, the rotating unit is a corner-pressing cylinder, and one end of the pressing rod is fixed to the rotating part of the corner-pressing cylinder.

[0013] Furthermore, the side of the clamping rod facing the corn placement platform is provided with several elastic clamping mechanisms, including a sleeve fixedly connected to the clamping rod at one end, an open sleeve at the other end and a movable rod coaxially inserted inside, the axis of the sleeve being perpendicular to the axis of the clamping rod, a spring being provided between the end of the movable rod inside the sleeve and the inner end face of the sleeve, a clamping plate being fixedly connected to the end of the movable rod protruding from the sleeve, and anti-detachment structures being provided on the movable rod and the sleeve to prevent the movable rod from slipping out of the sleeve.

[0014] Furthermore, the pressing plate is an arc-shaped arch plate, and the concave surface of the arc-shaped arch plate faces the corn placement platform, and the inner wall of the concave surface is provided with anti-slip texture. After the pressing rod is pressed down, the positions of several pressing plates correspond to several placement slots.

[0015] Furthermore, the anti-detachment structure includes an anti-detachment protrusion located at one end of the movable rod inside the sleeve, and an anti-detachment cap screwed onto one end of the sleeve opening. The anti-detachment cap has a movable hole, the diameter of which is larger than the diameter of the movable rod but smaller than the diameter of the anti-detachment protrusion.

[0016] Furthermore, the placement slot is provided with an installation hole, and the sensing device is a diffuse reflection photoelectric sensor. The diffuse reflection photoelectric sensor is installed in the installation hole, and the placement slot is provided with an installation wire groove.

[0017] The beneficial effects of this utility model are as follows: This utility model realizes an automated process of automatically pressing the corn after it is filled with corn and automatically releasing it after processing through the linkage of the sensing device, rotating unit and pressing rod. This effectively solves the problem of displacement and rolling of corn during cutting and conveying due to lack of fixation. Its elastic pressing mechanism transforms rigid pressure into flexible pressure, ensuring the tightening effect while avoiding damage to the corn. The anti-slip texture on the placement groove and pressing plate further enhances stability. This design improves the safety of cutting operations, the stability of processing quality and production efficiency as a whole. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1As shown, a movable fastening mechanism for a corn end removal device is disclosed. The corn end removal device includes a horizontally arranged machine base 1 and a guide rail 2 arranged on the machine base 1. In this embodiment, the guide rail 2 is configured as a pair and parallel to each other. Two cutting mechanisms 3 are mounted above the guide rail 2. The cutting mechanisms 3 perform longitudinal cutting, and the cutting surface is perpendicular to the movement direction of the guide rail 2. The movable fastening mechanism is configured in conjunction with the guide rail 2 and the cutting mechanisms 3. It includes a placement platform 4 slidably arranged on the guide rail 2. The placement platform 4 is slidably arranged on the pair of guide rails 2 by a slider 5 arranged below. A driving device 6 is provided on one side of the placement platform 4 to move the placement platform 4 to a designated position.

[0027] like Figure 2 As shown, the top surface of the placement platform 4 is provided with several parallel placement slots 7 perpendicular to the length direction of the guide rail 2, and the axis of the placement slots 7 is parallel to the length direction of the guide rail 2.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a fixing mechanism is provided on the placement platform 4 to fix the corn 20. The fixing mechanism includes a rotating unit 8 on both sides of the placement platform 4. A pressing rod 9 is vertically arranged on the rotating unit 8. The axis of the pressing rod 9 is perpendicular to the length direction of the guide rail 2. The rotating unit 8 can make the pressing rod 9 press down and rotate on one side of the placement platform 4 perpendicular to the length direction of the guide rail 2.

[0029] like Figure 2 , Figure 5 As shown, a sensing device 17 is provided in the placement slot 7. When corn 20 is placed in several placement slots 7, the rotating unit 8 is started, which drives the clamping rod 9 to rotate and clamp the corn 20. After the corn 20 is taken out, the rotating unit 8 drives the clamping rod 9 to lift.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the placement groove 7 is a through groove opened on the placement platform 4. The inner wall of the through groove is a concave arc surface, and the inner wall is provided with anti-slip texture 21 to enhance the stability of the corn 20 and prevent it from sliding or shifting during cutting.

[0031] like Figure 2 , Figure 3 , Figure 4 As shown, preferably, the rotating unit 8 is a rotary pressing cylinder, and one end of the pressing rod 9 is fixed to the rotating part of the rotary pressing cylinder. The rotary pressing cylinder drives the pressing rod 9 to achieve fast and precise pressing and resetting actions, thereby improving automation efficiency.

[0032] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, preferably, the pressing rod 9 is provided with several elastic pressing mechanisms on the side facing the placement platform 4, including a sleeve 10 fixedly connected to the pressing rod 9 at one end, the other end of the sleeve 10 being open and a movable rod 11 being coaxially inserted inside, the axis of the sleeve 10 being perpendicular to the axis of the pressing rod 9, a spring 12 being provided between the end of the movable rod 11 inside the sleeve 10 and the inner end face of the sleeve 10, a pressing plate 13 being fixedly connected to the end of the movable rod 11 protruding from the sleeve 10, and anti-detachment structures being provided on the movable rod 11 and the sleeve 10 to prevent the movable rod 11 from slipping out of the sleeve 10. The sleeve 10 and movable rod 11 structure buffered by the spring 12 can adapt to the pressing requirements of corn 20 of different diameters and avoid over-pressure damage to the corn 20.

[0033] like Figure 6 As shown, preferably, the anti-detachment structure includes an anti-detachment protrusion 14 located at one end of the movable rod 11 inside the sleeve 10, and an anti-detachment cover 15 screwed onto one open end of the sleeve 10. The anti-detachment cover 15 has a movable hole 16, the diameter of which is larger than the diameter of the movable rod 11 but smaller than the diameter of the anti-detachment protrusion 14. The anti-detachment protrusion 14 cooperates with the anti-detachment cover 15 to ensure that the movable rod 11 does not detach from the sleeve 10 during elastic extension and retraction, thereby improving the reliability of the mechanism.

[0034] like Figure 1 , Figure 3 , Figure 4 As shown, preferably, the pressing plate 13 is an arc-shaped arch plate, and the concave surface of the arc-shaped arch plate faces the placement platform 4, and the inner wall of the concave surface is provided with anti-slip texture 21. After the pressing rod 9 is pressed down, the positions of several pressing plates 13 correspond to several placement grooves 7. The design of the arc-shaped arch plate and the anti-slip texture 21 increases the contact area and applies force evenly, further preventing the corn 20 from sliding.

[0035] like Figure 2 , Figure 5 As shown, preferably, the placement groove 7 has an installation hole 18, and the sensing device 17 is a diffuse reflection photoelectric sensor. The diffuse reflection photoelectric sensor is installed in the installation hole 18, and the placement groove 7 has an installation groove 19. The diffuse reflection photoelectric sensor is installed in a concealed manner to detect the presence or absence of corn 20 and trigger the pressing action to avoid misoperation.

[0036] Additionally, it should be noted that in this solution, the drive device 6 moves the placement platform 4 horizontally, precisely positioning it at the designated cutting position. This can be an electric push rod or other linear drive device, as long as it enables the corn loading platform 20 to move and reach the designated position according to motion logic; details will not be elaborated here. The cutting mechanism 3 uses a conventional linear drive method (such as a cylinder-electric push rod) to drive the cutter to move vertically, performing direct up-and-down cutting operations on the corn end that has moved directly below it. Furthermore, the drive device 6, the cutting mechanism 3, and the aforementioned corner-pressing cylinder and diffuse reflection photoelectric sensor are all controlled by a controller (such as a PLC) and all require connection to an external power supply or air source; these will not be discussed further here.

[0037] The specific operation method of this utility model is as follows:

[0038] 1. Initial state confirmation:

[0039] The system is powered on and initialized. It is confirmed that the placement platform 4 is in the initial position between the pair of cutting mechanisms 3, the rotating unit 8 (corner pressing cylinder) is in the reset state, and all clamping rods 9 are in the raised position, ready for manual placement of corn 20 (or placement by a robotic arm, etc., which is not limited here).

[0040] 2. Load 20 tons of corn:

[0041] One by one, the ears of corn 20 are placed into the placement groove 7 on the top surface of the placement platform 4. The inner wall of each placement groove is a concave arc surface with anti-slip texture 21, which can initially stabilize the corn 20.

[0042] 3. Sensor detection and signal triggering:

[0043] Once corn 20 has been placed in all placement slots 7, the diffuse reflection photoelectric sensor installed at the bottom of each slot detects the presence of corn 20. After all sensors generate detection signals, these signals are sent to the control system (PLC or dedicated controller), indicating that the corn 20 has been loaded and is in place.

[0044] 4. Activate the fixing (pressing) mechanism:

[0045] After the control system receives a signal that all slots contain corn 20, it issues a command to start the rotating unit 8 (corner pressing cylinder). The command to start the rotating unit 8 can be set to be sent with a delay to prevent the rotating unit 8 from starting immediately after the corn 20 is put in, which could easily cause the operator or machine to collide with the clamping rod 9.

[0046] The rotating part of the corner pressing cylinder starts to move, driving the pressing rod 9 to rotate downward from one side of the placement platform 4 in a direction perpendicular to the length of the guide rail 2.

[0047] The clamping rod 9 is pressed down, causing its elastic clamping mechanism (sleeve 10, spring 12, movable rod 11 and clamping plate 13) to contact the corn 20.

[0048] The clamping plate 13 (an arc-shaped arch with an anti-slip texture on the concave surface) above each corn 20 adaptively presses against corn 20 of different diameters under the cushioning effect of the spring 12, ensuring uniform clamping force without damaging the corn 20. The anti-detachment structure (anti-detachment protrusion 14 and anti-detachment cover 15) ensures that the movable rod 11 will not detach from the sleeve 10.

[0049] The corn kernels are securely fixed in their respective slots to prevent them from sliding or shifting during subsequent cutting.

[0050] 5. Move corn 20 to the cutting station:

[0051] After the corn 20 is fixed, the control system activates the drive device 6 (such as an electric push rod, servo motor, stepper motor, or cylinder). The drive device 6 drives the slider 5 at the bottom of the placement table 4 to slide on the guide rail 2. The placement table 4, carrying the compressed corn 20, moves from the initial middle position along the guide rail 2 to the work position directly below the first designated cutting mechanism 3.

[0052] 6. Perform end cutting (first time):

[0053] After the placement platform 4 reaches the predetermined position, the drive device 6 stops, and the position sensor (such as a limit switch) confirms that it is in place.

[0054] The control system triggers the cutting mechanism 3 (e.g., a cylinder-driven cutter) at this station. The cutter moves downwards, completing the cutting operation on one end of the corn 20 located below it. After cutting, the cutter returns to its original position.

[0055] 7. Move to the next workstation and cut (second time):

[0056] The drive unit 6 restarts, moving the placement platform 4 along the guide rail 2 to the position directly below the next cutting mechanism 3. Once in position, the cutting mechanism 3 at that position activates, completing the cutting operation on the other end of the corn 20.

[0057] 8. Return to the initial position and release the corn 20:

[0058] After all the cutting operations at both ends are completed, the drive unit 6 drives the placement platform 4 back to the initial middle position. Upon reaching the middle position, the control system controls the rotating unit 8 (corner pressing cylinder) to reset, causing the clamping rod 9 to rotate upwards and lift, thus disengaging the elastic clamping mechanism from the corn 20. The clamping rod 9 then fully resets to the lifted state.

[0059] 9. Unloading:

[0060] The operator removes the corn kernels 20 that have had their ends removed from the placement trough 7. After all the corn kernels 20 have been removed, the diffuse reflection photoelectric sensor in the trough detects that there are no corn kernels 20, and the system returns to its initial state, waiting for the next loading.

[0061] It should be emphasized that the specific timing logic needs to be adjusted according to the actual production situation.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
