Description

Technical Field

[0001] This utility model relates to the field of citrus canning technology, and in particular to a cap tightening device for citrus canning. Background Technology

[0002] Citrus preserves are mainly made from citrus fruits such as oranges, grapefruits, tangerines, and lemons. These fruits are rich in nutrients such as vitamin C, flavonoids, and fiber, which not only give the preserves a unique flavor but also provide certain health benefits.

[0003] Reference to the utility model patent with authorization announcement number CN220056295U, a bottle cap tightening device is disclosed, including a control cabinet, a frame and a bottle placement frame. The frame is provided with a first driving mechanism, a second driving mechanism and a clamping mechanism from top to bottom. The first driving mechanism controls the second driving mechanism to move up and down. The second driving mechanism is provided with a tightening mechanism. The second driving mechanism drives the tightening mechanism to move up and down. The tightening mechanism is located directly above the bottle placement frame. The bottle placement frame is located in the clamping mechanism.

[0004] The aforementioned patent requires the bottle to be placed inside the bottle placement frame before the capping operation can be performed. This requires continuous manual assistance and results in low production efficiency. To address the shortcomings of the above technology, we propose a bottle cap tightening device for citrus canning. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cap tightening device for processing citrus canned goods.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bottle cap tightening device for citrus canning includes a support frame, a conveyor belt fixedly installed on the inner side of the support frame, and a bottle cap clamping mechanism above the conveyor belt. The bottle cap clamping mechanism includes an electric telescopic rod, a cone fixedly installed on the output end of the electric telescopic rod, a structural base plate below the cone, three lateral sliding grooves on the side of the cone, a round rod slidably engaged inside the lateral sliding grooves, a folding rod fixedly connected to the lower side of the round rod, a rotating groove on the structural base plate, the folding rod rotatably mounted inside the rotating groove, and an arc-shaped seat fixedly installed at the lower end of the folding rod.

[0008] Furthermore, a photoelectric sensor is fixedly installed at the center of the bottom of the structural base plate.

[0009] By adopting the above technical solution, the photoelectric sensor is used to detect the position of the bottle body and to position the bottle cap clamping mechanism relative to the bottle body, which facilitates the subsequent capping process.

[0010] Furthermore, clamping protrusions are evenly distributed on the inner side of the arc-shaped seat.

[0011] Furthermore, a support mechanism is provided on the upper side of the support frame. The support mechanism includes a support frame, a drive motor is fixedly installed on the upper side of the support frame, a rotating shaft is fixedly installed on the output end of the drive motor, the rotating shaft rotates through to the lower side of the support frame, and a mounting top plate is fixedly installed at the lower end of the rotating shaft.

[0012] By adopting the above technical solution, when the drive motor starts, it can drive the lower cap clamping mechanism to rotate and perform the capping operation.

[0013] Furthermore, the electric telescopic rod is fixedly installed at the bottom of the mounting top plate, and a connecting plate is fixedly connected between the structural base plate and the mounting top plate.

[0014] Furthermore, ear seats are symmetrically fixedly installed on both sides of the support frame, and a hydraulic lifting rod is fixedly connected between the ear seats and the upper side of the support frame.

[0015] By adopting the above technical solution, the hydraulic lifting rod indirectly controls the height of the bottle cap clamping mechanism by adjusting the height of the support frame, enabling it to approach the top of the bottle for capping and then return to its original position after the capping operation is completed.

[0016] Furthermore, a controller is fixed on the side wall of the support frame.

[0017] Furthermore, the conveyor belt carries citrus canning jars, and screw caps are fastened to the upper ports of the citrus canning jars.

[0018] By adopting the above technical solution, the citrus canning bottles are automatically transported by a conveyor belt. When the citrus canning bottles are transported to the bottom of the cap clamping mechanism, the subsequent automatic capping work can be carried out, thereby improving the degree of automation and increasing production efficiency.

[0019] Furthermore, electric push rods are symmetrically fixedly installed on the upper side of the support frame, and clamping plates are fixedly installed on the output end of the electric push rods.

[0020] Furthermore, the clamping plate is made of rubber.

[0021] By adopting the above technical solution, the inner side of the clamping plate has a good damping effect. Therefore, when the clamping plate wraps and clamps the outer side of the bottle, it can ensure that the bottle does not rotate with the cap during the capping process, thus ensuring the smooth progress of the capping operation.

[0022] Compared with related technologies, the cap tightening device for citrus canning proposed in this utility model has the following advantages:

[0023] In this invention, a cap tightening device for citrus canning is described. Through a cap clamping mechanism, when a citrus canning bottle with a cap attached is conveyed to the lower side of the cap clamping mechanism, a photoelectric sensor at the center of the bottom of the structural base plate senses the position of the bottle. When the bottle is directly below the cap clamping mechanism, the controller intermittently stops the conveyor belt. Subsequently, by lowering the support frame, the arc-shaped seat at the lower end of the folding rod approaches the outer side of the cap on the upper part of the bottle. At this time, the electric telescopic rod retracts, and the sliding contact between the conical lateral groove and the upper round rod of the folding rod causes the lower end of the folding rod to flip inward, thereby gradually driving the arc-shaped seat to abut inward, thus stably clamping the cap inside. By controlling the extension and retraction of the electric telescopic rod, caps of different sizes can be clamped, and the capping process can then begin. The entire process requires no manual intervention, has a high degree of automation, improves production efficiency, and enhances practicality. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figures 1-5 A bottle cap tightening device for processing citrus canned goods includes a support frame 1, a conveyor belt 2 fixedly installed on the inner side of the support frame 1, and a bottle cap clamping mechanism 7 arranged above the conveyor belt 2. The bottle cap clamping mechanism 7 includes an electric telescopic rod 71, a cone 72 fixedly installed on the output end of the electric telescopic rod 71, a structural base plate 74 arranged below the cone 72, three lateral sliding grooves 73 opened on the side of the cone 72, a round rod 78 slidably engaged in the inner side of the lateral sliding grooves 73, a folding rod 79 fixedly connected to the lower side of the round rod 78, a rotating groove 77 opened on the structural base plate 74, the folding rod 79 rotatably installed in the inner side of the rotating groove 77, and an arc-shaped seat 710 fixedly installed at the lower end of the folding rod 79.

[0032] With the above structure, activating the electric telescopic rod 71 can push the lateral sliding groove 73 on the inner side of the cone 72 to slide into contact with the round rod 78 on the upper side of the folding rod 79, thereby causing the folding rod 79 to flip, so that the distance between the arc-shaped seat 710 at the lower end of the folding rod 79 and the center position changes, which is used to clamp bottle caps of different sizes.

[0033] In this embodiment, a support mechanism 6 is provided on the upper side of the support frame 1. The support mechanism 6 includes a support frame 61. A drive motor 64 is fixedly installed on the upper side of the support frame 61. A rotating shaft 65 is fixedly installed on the output end of the drive motor 64. The rotating shaft 65 rotates through to the lower side of the support frame 61, and a mounting top plate 66 is fixedly installed at the lower end of the rotating shaft 65. An electric telescopic rod 71 is fixedly installed at the bottom of the mounting top plate 66. A connecting plate 75 is fixedly connected between the structural base plate 74 and the mounting top plate 66.

[0034] With the above structure, when the drive motor 64 starts, it can drive the entire bottle cap clamping mechanism 7 to rotate. When the arc seat 710 clamps the bottle cap, it can drive the bottle cap to be screwed on the upper end of the citrus canning bottle 3.

[0035] In this embodiment, ear seats 62 are symmetrically fixedly installed on both sides of the support frame 61, and a hydraulic lifting rod 63 is fixedly connected between the ear seats 62 and the upper side of the support frame 1.

[0036] Through the above structure, the hydraulic lifting rod 63 can adjust the height of the support frame 61 by lifting, and thus can adjust the vertical height of the arc-shaped seat 710 at the lower end of the folding rod 79.

[0037] In this embodiment, a photoelectric sensor 76 is fixedly installed at the center of the bottom of the structural base plate 74.

[0038] With the above structure, the photoelectric sensor 76 is used to detect the position of the bottle.

[0039] In this embodiment, clamping protrusions 711 are evenly distributed on the inner side of the arc-shaped seat 710.

[0040] Through the above structure, the setting of the clamping protrusions 711 enables the arc surface seat 710 to provide stable friction after clamping the bottle cap, thus preventing slippage during the capping process.

[0041] In this embodiment, a controller is fixed on the side wall of the support frame 1.

[0042] Through the above structure, the controller is used to control the coordinated operation of various electrical components, improve the degree of automation, and thus improve production efficiency.

[0043] In this embodiment, citrus canning jars 3 are conveyed on the conveyor belt 2, and screw caps are fastened to the upper port of the citrus canning jars 3.

[0044] In this embodiment, electric push rods 4 are symmetrically fixedly installed on the upper side of the support frame 1, and clamping plates 5 are fixedly installed on the output end of the electric push rods 4. The clamping plates 5 are made of rubber.

[0045] Through the above structure, the clamping plate 5 can provide a stable clamping effect on the bottle body, preventing the bottle body from rotating in reverse during the capping process.

[0046] In this invention, during use, the conveyor belt 2 continuously operates, smoothly transporting the capped citrus canning jars 3 along a set track. During transport, the citrus canning jars 3 gradually approach the bottom of the cap clamping mechanism 7. When the citrus canning jars 3 approach the cap clamping mechanism 7, the photoelectric sensor 76 at the center of the bottom of the structural base plate 74 starts working to detect the position of the jar. When it detects that the jar is directly below the cap clamping mechanism 7, the photoelectric sensor 76 transmits a signal to the controller. The controller receives the signal from the photoelectric sensor 76. Then, the control conveyor belt 2 stops intermittently, and the electric push rods 4 symmetrically installed on the upper side of the support frame 1 extend, so that the rubber clamping plate 5 wraps and clamps the outside of the citrus canning bottle 3. The controller starts the hydraulic lifting rod 63, which retracts, driving the support frame 61 and the entire bottle cap clamping mechanism 7 connected to it to descend. As the mechanism descends, the arc-shaped seat 710 at the lower end of the folding rod 79 gradually approaches the outside of the bottle cap at the upper end of the citrus canning bottle 3. When the arc-shaped seat 710 approaches the bottle cap, the electric telescopic rod 71 is activated to retract. When rod 71 retracts, the cone 72 fixed at its output end moves upward, and the lateral groove 73 on the side of cone 72 slides against the round rod 78. Since the round rod 78 is fixedly connected to the folded rod 79, and the folded rod 79 is rotatably installed in the rotating groove 77 of the structural base plate 74, this sliding contact causes the lower end of the folded rod 79 to flip inward, driving the arc surface seat 710 to gradually move inward, finally stabilizing the bottle cap inside the arc surface seat 710. After the bottle cap is stably clamped, the drive motor 64 is started, and the rotating shaft 65 at the output end of the drive motor 64 rotates. The top plate 66 and the bottle cap clamping mechanism 7 fixed thereon rotate as a whole. Since the arc seat 710 tightly clamps the bottle cap, the bottle cap is tightened on the upper end of the citrus canning bottle 3 during the rotation of the clamping mechanism. After the cap is tightened, the drive motor 64 stops rotating. Then, the hydraulic lifting rod 63 is extended, which drives the support frame 61 and the bottle cap clamping mechanism 7 to rise and reset. At the same time, the electric push rod 4 retracts, and the controller controls the conveyor belt 2 to start again, conveying the citrus canning bottle 3 with the cap tightened away for subsequent processes.
