Description

Technical Field

[0001] This utility model relates to the field of fruit processing equipment technology, specifically to a positioning device for pineapples. Background Technology

[0002] In the field of pineapple processing, precise positioning of pineapples is a key factor in ensuring the quality and efficiency of subsequent processing. Traditional pineapple feeding and positioning methods have many drawbacks, which seriously affect the overall effect of pineapple processing.

[0003] In existing pineapple feeding and peeling devices, most adopt a method of opening clamps on both sides. In actual operation, the pineapple falls directly to the bottom of the clamp, and then the clamp clamps to position the pineapple. However, the rough skin of the pineapple makes it difficult to achieve ideal positioning on both sides during the clamping process. The rough skin cannot form a stable and tight contact with the clamp, which may cause the pineapple to shake or shift within the clamp, making it impossible to fix it accurately in the predetermined position. This, in turn, affects the accuracy of subsequent peeling and other processing steps, and reduces product quality.

[0004] In addition, traditional clamps lack an effective synchronization mechanism during opening and closing. It is difficult to keep the speed and timing of opening or closing of the clamps on both sides consistent. This makes the pineapple susceptible to offset forces when it is placed into the clamp. When the clamps on both sides move asynchronously, the pineapple may shift its position and fail to enter the center positioning area of ​​the clamp smoothly if one clamp moves first and the other does not respond in time. This further increases the difficulty and uncertainty of positioning.

[0005] In view of the above-mentioned problems of traditional pineapple positioning devices, it is particularly necessary to develop a device that can accurately and stably position pineapples. This utility model is an improvement and innovation aimed at addressing these shortcomings, and provides a new type of positioning device for pineapples to solve the problem of poor performance of traditional positioning methods, thereby improving the positioning accuracy and overall quality of pineapple processing. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a positioning device for pineapples. This device, through structural improvements to the top and bottom clamping plates, allows the pineapple to smoothly enter the waiting area and be stably fixed in the clamping area. This effectively overcomes the shortcomings of traditional clamps, such as inaccurate positioning and easy wobbling and displacement due to the rough skin of the pineapple, thus improving positioning accuracy. The top and bottom clamping plates open and close synchronously via gear linkage, preventing the pineapple from being affected by offset forces and enhancing positioning accuracy and reliability. Furthermore, a buffer device between the clamping plates reduces impact during clamping, effectively minimizing damage to the pineapple and ensuring its quality.

[0007] The technical solution of this utility model is as follows:

[0008] A positioning device for pineapples includes a mounting plate, a top clamping frame, a bottom clamping frame, a top clamping plate, and a bottom clamping plate. One end of the top clamping frame and the bottom clamping frame are rotatably mounted on the mounting plate, and the top clamping frame and the bottom clamping frame are linked by meshing gears. An elastic pre-tightening component is provided in the middle of the top clamping frame and the bottom clamping frame to provide a pre-tightening force in the clamping direction. The other end of the top clamping frame and the bottom clamping frame are respectively fixedly mounted with the top clamping plate and the bottom clamping plate. The top clamping plate consists of a top straight plate and an upper concave plate, and the bottom clamping plate consists of a bottom straight plate and a lower concave plate. A funnel-shaped waiting area that is wider at the top and narrower at the bottom is formed between the top straight plate and the bottom straight plate. A feeding port is formed between the top straight plate and the upper concave plate and the bottom straight plate. When the top clamping frame and the bottom clamping frame are clamped, the opening size of the feeding port is smaller than the outer diameter of the pineapple, and when it is opened, the opening size is larger than the outer diameter of the pineapple. A clamping area that matches the shape of the pineapple is formed between the upper concave plate and the lower concave plate.

[0009] The elastic preload assembly is a spring, and the two ends of several springs are fixedly connected to the top clamping plate frame and the bottom clamping plate frame, respectively.

[0010] A face mask is installed above the top clamping plate and is fixedly connected to the mounting plate.

[0011] The mounting plate is equipped with a fixing block, and the top clamping plate and the bottom clamping plate are respectively mounted on the fixing block via bearings.

[0012] The top clamping frame consists of two top clamping plates and several top connecting rods arranged between the two top clamping plates.

[0013] The bottom clamping frame consists of two bottom clamping plates and several bottom connecting rods set between the two bottom clamping plates.

[0014] A buffer device is installed between the top clamping frame and the bottom clamping frame.

[0015] The cushioning device includes cushioning screws and cushioning components respectively installed on the top clamping frame or the bottom clamping frame, and a cushioning layer is provided at the position where the cushioning screws and the cushioning components come into contact.

[0016] The buffer layer is made of rubber.

[0017] A tension chain is fixedly connected to the bottom of the bottom clamping frame, and the other end of the tension chain is fixedly connected to the tension drive source.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model discloses a positioning device for pineapples. The positioning device for pineapples achieves accurate and stable positioning of pineapples. The structural design of the top clamping plate and the bottom clamping plate allows the pineapple to smoothly enter the waiting area and be stably fixed in the clamping area when clamped. It overcomes the problem of inaccurate positioning and easy shaking and displacement caused by the rough skin of pineapples in traditional clamps, and improves the positioning accuracy.

[0020] 2. The present invention discloses a positioning device for pineapples. The positioning device for pineapples can achieve synchronous opening and closing. The top clamping plate and the bottom clamping plate are linked by meshing gears to ensure the synchronicity of the opening and closing of the clamps on both sides.

Detailed Implementation

[0032] like Figure 1 and Figure 2 As shown, the positioning device for pineapples mainly includes a mounting plate 100, a top clamping plate frame 200, a bottom clamping plate frame 300, a top clamping plate 400, a bottom clamping plate 500, a gear 1000, a spring 800, a face shield 700, a fixing block 110, a tension chain 900, a buffer screw 1100, a buffer mounting component 1200, a buffer component 1300, and other components.

[0033] like Figure 3 As shown, the mounting plate 100 serves as the mounting base for the entire device, and a fixing block 110 is provided on it. One end of the top clamping plate 200 and the bottom clamping plate 300 are respectively mounted on the fixing block 110 through bearings, so that the two can rotate around the mounting point.

[0034] like Figure 4 As shown, the top clamping frame 200 consists of two top clamping plates 210 and a number of top connecting rods 220 disposed between the two top clamping plates 210; the bottom clamping frame 300 consists of two bottom clamping plates 310 and a number of bottom connecting rods 320 disposed between the two bottom clamping plates 310.

[0035] The top clamping frame 200 and the bottom clamping frame 300 are linked by meshing gears 1000, that is, when one clamping frame rotates, the other clamping frame can be driven to rotate synchronously in the opposite direction through gear transmission.

[0036] Several springs 800 are provided in the middle of the top clamping frame 200 and the bottom clamping frame 300. The two ends of the springs 800 are fixedly connected to the top clamping frame 200 and the bottom clamping frame 300 respectively, providing a preload force to the clamping frame in the clamping direction.

[0037] The other ends of the top clamping plate 200 and the bottom clamping plate 300 are respectively fixedly installed with a top clamping plate 400 and a bottom clamping plate 500.

[0038] like Figure 5 and Figure 6 As shown, the top clamping plate 400 is composed of a top straight plate 410 and an upper concave plate 420, and the bottom clamping plate 500 is composed of a bottom straight plate 510 and a lower concave plate 520. A funnel-shaped waiting area with a wider top and narrower bottom is formed between the top straight plate 410 and the bottom straight plate 510. A feeding port is formed between the joint of the top straight plate 410 and the upper concave plate 420 and the bottom straight plate 510. When the top clamping plate frame 200 and the bottom clamping plate frame 300 are clamped, the opening size of the feeding port is smaller than the outer diameter of the pineapple 600. When it is opened, the opening size is larger than the outer diameter of the pineapple 600. A clamping area matching the shape of the pineapple 600 is formed between the upper concave plate 420 and the lower concave plate 520.

[0039] A face shield 700 is installed above the top clamping plate 200. The face shield 700 is fixedly connected to the mounting plate 100 and serves as a protective device.

[0040] A tension chain 900 is fixedly connected to the bottom of the bottom clamping plate frame 300. The other end of the tension chain 900 is fixedly connected to a tension drive source (such as a cylinder or electric cylinder). The bottom clamping plate frame 300 can be rotated by pulling the tension chain 900 through the tension drive source.

[0041] In addition, a buffer device is provided between the top clamping frame 200 and the bottom clamping frame 300. The buffer device includes a buffer screw 1100 and a buffer member 1300 respectively installed on the top clamping frame 200 or the bottom clamping frame 300. The buffer screw 1100 is connected to the buffer mounting member 1200 fixed on the top clamping frame 200 or the bottom clamping frame 300 by thread engagement. A buffer layer is provided at the contact position between the buffer screw 1100 and the buffer member 1300. In this embodiment, the buffer layer is made of rubber and is used to buffer the clamping force on the pineapple 600 when clamping.

[0042] This device utilizes the synchronicity of gear transmission and the preload of springs to achieve the positioning and clamping of the pineapple. The tension drive source (such as manual pulling or using a cylinder, electric cylinder, etc.) pulls the tension chain 900, which drives the bottom clamping plate 300 to rotate. Then, through the transmission of gear 1000, the top clamping plate 200 rotates synchronously in the opposite direction, thereby realizing the opening and clamping action of the clamp. The spring 800 always provides a preload force in the clamping direction to the clamping plate, ensuring that the clamp is in a clamping tendency in its natural state. The buffer device is used to buffer the clamping force when clamping the pineapple to avoid damage to the pineapple.

[0043] The device operates as follows:

[0044] Pineapple placed in the waiting area: Place the pineapple 600 to be processed in the funnel-shaped waiting area formed by the top straight plate 410 and the bottom straight plate 510. At this time, because the feed inlet is clamped and the opening size is smaller than the outer diameter of the pineapple 600, the pineapple 600 will not fall off.

[0045] Pull the bottom clamping frame: The tension drive source pulls the tension chain 900, which drives the bottom clamping frame 300 to rotate around the mounting point. At the same time, through the meshing gears 1000, the top clamping frame 200 rotates in the opposite direction. The two gears open the clamps in time, increasing the size of the feed inlet opening.

[0046] The pineapple falls into the positioning fixture and is clamped: When the fixture is fully opened, the pineapple 600 in the waiting area falls into the clamping area formed by the upper concave plate 420 and the lower concave plate 520 under the action of gravity, which matches the shape of the pineapple 600. Then, the tension drive source stops pulling the tension chain 900. Under the pre-tightening force of the spring 800, the top clamping plate frame 200 and the bottom clamping plate frame 300 rotate in opposite directions, and the fixture gradually clamps. At this time, the buffer screw 1100 in the buffer device contacts the buffer component 1300, and the rubber buffer layer plays a buffering role to avoid excessive clamping force from damaging the pineapple 600. Finally, the pineapple 600 is stably clamped in the clamping area.

[0047] The push rod pushes the pineapple away to the next process, and at the same time, it pulls the bottom pull rod when resetting: the external push rod pushes the pineapple 600 clamped in the clamping area away and sends it to the next process for further processing. After the push rod pushes the pineapple 600 away, the tension drive source pulls the tension chain 900 again, which drives the bottom clamping plate 300 to rotate. Through the gear 1000, the top clamping plate 200 rotates synchronously in the opposite direction, and the clamp opens again.

[0048] The next pineapple falls into the positioning fixture and is clamped, and the positioning and feeding are carried out in a cyclical manner. At this time, the next pineapple to be processed 600 falls from the waiting position into the open clamping area of ​​the fixture. The above operation is repeated to realize the cyclical positioning and feeding of pineapples.
