Description

Technical Field

[0001] This utility model relates to the field of brewing production technology, and in particular to a bottle cap installation device for wine bottles. Background Technology

[0002] Traditional wine bottle sealing processes mainly rely on manual operation or semi-automated equipment, which presents the following technical challenges: Inefficient: Manually placing bottle caps requires individual operation, which is difficult to match the high-speed conveying requirements of modern production lines.

[0003] Unstable sealing: Uneven pressure when manually pressing the cap can easily lead to poor sealing, posing a risk of leakage or oxidation.

[0004] Insufficient compatibility: The fixed clamping mechanism is difficult to adapt to different bottle diameter specifications, and the cost of changing molds is high.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a bottle cap installation device that would have greater industrial value. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a bottle cap installation device.

[0007] This utility model discloses a bottle cap installation device, which includes a frame. A conveyor belt is installed on the top of the frame via a support rod. The conveyor belt is used to continuously convey bottles with caps. Above the conveyor belt are multiple sets of bottle cap installation heads that can move up and down. On both sides of the conveyor belt and below the bottle cap installation heads are clamping mechanisms for holding the bottle. The bottle cap mounting head includes a clamping claw for gripping the upper side of the bottle. The middle part of the clamping claw is movably mounted on the support sleeve via a shaft. The top of the clamping claw is movably connected to the pull head via a shaft and a connecting rod. The top of the pull head is a rotating shaft, which is connected to the telescopic rod of the pull-out cylinder. A pressure plate is fixedly installed at the bottom of the support sleeve, and a retractable top block is installed inside the pressure plate.

[0008] The bottle cap installation device mainly consists of a frame, a conveyor belt, and a bottle cap installation head. The frame is fixed to the conveyor belt by support rods for continuous conveying of bottles. The bottle cap installation head is raised and lowered above the conveyor belt, and clamping mechanisms are configured on both sides for bottle positioning. The bottle cap installation head includes core components such as clamping claws, support sleeves, and pressure plates. The clamping claws are hinged to the pull head via connecting rods. The top of the pull head is connected to a rotating shaft and driven by a pull-out cylinder. The pressure plate installed at the bottom of the support sleeve has a built-in retractable top block. The whole device forms a collaborative bottle cap pressing system.

[0009] Furthermore, the pull-out cylinder is mounted on the support plate via a connecting rod, and the support plate is fixed to the mounting base via a connecting rod. The tail end of the mounting base is fixedly connected to the lifting plate. The lifting plate is movably mounted to the mounting plate via a slide rail slider. An end plate is fixed to the rear side of the mounting plate, and both ends of the end plate are sleeved on the guide rod via guide sleeves. The upper and lower ends of the guide rod are fixed between the frame and the top plate, respectively. A lifting motor is mounted on the top plate, and a threaded sleeve is located in the middle of the end plate. The threaded sleeve engages with the screw rod connected to the lifting motor.

[0010] The device's pull-out cylinder is connected to the support plate via a linkage system. The support plate is fixed to the lifting plate via a mounting base. The lifting plate moves relative to the mounting plate via a slide rail slider mechanism. The end plate on the rear side of the mounting plate slides up and down along the guide rod via a guide sleeve. The two ends of the guide rod are fixed between the frame and the top plate, respectively. The lifting motor on the top plate engages with the screw sleeve in the center of the end plate via a screw, forming a complete lifting drive system to achieve precise height adjustment of the bottle cap mounting head.

[0011] Furthermore, a rotating sleeve is movably mounted on the mounting base via bearings. A rotating shaft is mounted inside the rotating sleeve, which can be raised and lowered via a key and keyway. The top end of the rotating shaft is movably mounted inside the connecting sleeve via a bearing. The connecting sleeve is fixedly connected to the telescopic rod of the pull-out cylinder via a flange. A driven gear is fixed to the upper end of the rotating sleeve via bolts. The rotating shaft passes through the through hole in the middle of the driven gear. A rotary motor is mounted on the upper side of the support plate. The output shaft of the rotary motor passes through the support plate and is fitted with a drive gear that meshes with the driven gear.

[0012] The mounting base of the device achieves rotation by supporting the rotating sleeve with bearings. The rotating shaft moves up and down within the rotating sleeve via a keyway structure. Its top end engages with the connecting sleeve via a bearing, and the connecting sleeve is fixed to the telescopic rod of the pull-out cylinder via a flange. The driven gear is fixed at the upper end of the rotating sleeve and forms a through-sleeve structure with the rotating shaft. The rotary motor installed above the support plate meshes with the driven gear via the drive gear on the output shaft, forming a complete rotary drive system that achieves synchronous pressing and rotation during bottle cap installation.

[0013] Furthermore, a spring sleeve with a through hole is fixed in the middle of the lower part of the pressure plate. The pressure rod is inserted into the spring sleeve. The upper end of the pressure rod is a limiting ring that protrudes outward and contacts the upper edge of the spring sleeve. The lower section of the pressure rod is a threaded section. An adjusting nut is screwed into the threaded section. A pressure head with a screw hole of the same diameter is installed at the lower end of the adjusting nut. A spring is sleeved on the pressure rod. The lower end of the spring contacts the adjusting nut, and the upper end of the spring contacts the lower end face of the pressure plate.

[0014] A spring sleeve with a through hole is fixed below the pressure plate. The pressure rod passes through the spring sleeve and is axially limited by the upper limiting ring. The lower section of the pressure rod has a threaded section and is screwed into an adjusting nut. A pressure head with a threaded hole of the same diameter is installed at the bottom of the adjusting nut. A spring is sleeved on the outside of the pressure rod. The two ends of the spring contact the lower end face of the pressure plate and the adjusting nut respectively, forming an elastic pressing structure with adjustable pressure. The spring preload can be changed by rotating the adjusting nut, so as to achieve precise control of the bottle cap pressing force.

[0015] Furthermore, the clamping mechanism includes two sets of mirror-arranged uprights mounted on the frame. Two support frames are mounted on the top of the uprights. Two sets of clamping cylinders are mirror-arranged on the inner side of the two support frames. The telescopic rods of the clamping cylinders are fixedly connected to the clamping frames. Multiple clamping blocks are mirror-arranged on the inner side of the clamping frames on both sides. The surface of the clamping blocks has concave grooves.

[0016] The clamping mechanism consists of two sets of mirror-symmetrical uprights fixed to the machine frame to form the main frame. Two sets of clamping cylinders are symmetrically installed on the inner side of the support frame at the top of the uprights. The cylinder extension rod drives the clamping frame to move linearly. The inner side of the clamping frame on both sides is evenly distributed with clamping blocks with concave grooves. The cylinders push them synchronously to form a centering clamping structure. The curved surface of the grooves realizes the adaptive positioning and flexible clamping of the workpiece, ensuring the stability and positioning accuracy of the clamped part during the processing.

[0017] Furthermore, the support frame has sliding sleeves fitted onto the uprights at both ends, a crossbar is fixed at the top of the uprights, an adjusting screw is movably mounted on the upper end of the crossbar via a bearing, a threaded sleeve is fitted onto the adjusting screw in the middle of the support frame, and an adjusting wheel is mounted on the upper end of the adjusting screw.

[0018] The support frame is slidably engaged with the upright through sliding sleeves at both ends. A rotatable adjusting screw is installed on the crossbar fixed at the top of the upright. The screw passes through the threaded sleeve in the middle of the support frame and extends to the top to connect with the adjusting wheel. By manually rotating the adjusting wheel, the screw is driven to rotate, which causes the support frame to rise and fall vertically along the upright, realizing stepless adjustment of the overall height of the clamping mechanism. This ensures the precise positioning requirements of workpieces of different specifications, while maintaining structural stability and ease of operation.

[0019] By means of the above-described solution, the present invention has at least the following advantages: The adaptive capping system, through the coordinated action of the elastic pressure rod and the adjustable pressure head, combined with the rotational pressing action, ensures that the cap is subjected to uniform force and consistent sealing, completely solving the leakage and oxidation problems caused by uneven pressure in traditional processes; The dynamic clamping mechanism utilizes a cylinder-driven clamping block and a lifting and adjusting structure for the upright to achieve stepless clamping and height adjustment within the bottle body. It is compatible with all bottle sizes and requires no mold replacement. The collaborative control mechanism integrates continuous material feeding from the conveyor belt, precise positioning of the clamping mechanism, and synchronous rotation and pressing of the pressing head, thereby improving the efficiency of capping through electromechanical collaboration.

[0020] This device restructures the sealing process chain through mechanical innovation, achieving a flexible, high-speed, and commission-free production transformation while ensuring zero-leakage sealing, resulting in significant overall benefits.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] See Figures 1-3 The bottle cap installation device consists of a frame 1 and a conveyor belt 2 fixed above it by a support rod, forming a basic frame. Multiple sets of liftable bottle cap installation heads 3 are arranged above the conveyor belt 2, and clamping mechanisms are configured on both sides for bottle positioning. The core components of the bottle cap installation head 3 include a clamping claw 4 hinged to the support sleeve 5, a pull head 7 linked to the clamping claw 4 through a connecting rod 6, a rotating shaft 21 that drives the pull head 7, and a pull-out cylinder 8. The pressure plate 9 installed at the bottom of the support sleeve 5 has a built-in retractable top block 10. The entire mechanism achieves continuous operation of precise gripping, positioning, and pressing of bottle caps by coordinating the opening and closing of the clamping claw 4 and the lifting and lowering of the pressure plate 9 driven by the cylinder.

[0026] See Figure 5 and Figure 7 The device transmits power through a connecting rod between a pull-out cylinder 8 and a support plate 11. The support plate 11 is fixed to the mounting base 12 via a connecting rod. The tail end of the mounting base 12 is rigidly connected to the lifting plate 13. The lifting plate 13 forms a relative sliding fit with the mounting plate 14 through a slide rail slider mechanism. The end plate 18 on the rear side of the mounting plate 14 moves vertically along the guide rod 15 through a guide sleeve. The two ends of the guide rod 15 are respectively anchored to the frame 1 and the top plate 16 to form a stable frame. The lifting motor 17 mounted on the top plate 16 is driven by the threaded engagement of the screw 19 with the central screw sleeve of the end plate 18 to form a complete electromechanical linkage lifting system, realizing the precise height adjustment function of the bottle cap mounting head 3.

[0027] See Figure 4 and Figure 5The device achieves rotation by supporting the rotating sleeve 20 with bearings in the mounting base 12. The rotating shaft 21 moves up and down within the rotating sleeve 20 via a keyway structure. Its top end is connected to the connecting sleeve 22 via a bearing. The connecting sleeve 22 is rigidly fixed to the telescopic rod of the pull-out cylinder 8 via a flange. The driven gear 23 is bolted to the upper end of the rotating sleeve 20. The rotating shaft 21 passes through the central through hole of the driven gear 23 to form a linkage structure. The rotary motor 24 mounted on the upper side of the support plate 11 meshes with the driven gear 23 via the drive gear 25 on the output shaft, forming a complete rotary pressing power system, which realizes the precise coordination of the lifting and rotating movements of the rotating shaft 21 during the bottle cap installation process.

[0028] See Figure 3 and Figure 6 The device forms a guiding structure through a spring sleeve 26 fixed to the bottom of the pressure plate 9. The pressure rod 27 is inserted into the spring sleeve 26 and is axially constrained by a limiting ring 28. The threaded section at the lower end of the pressure rod 27 is fitted with an adjusting nut 29 to adjust the pressing height. The pressure head 30 connected to the bottom of the adjusting nut 29 is in direct contact with the bottle cap. The upper end of the spring 31 sleeved on the outside of the pressure rod 27 abuts against the lower end face of the pressure plate 9, and the lower end contacts the adjusting nut 29 to form an elastic buffer system. The entire mechanism achieves precise control of pressure regulation and buffering function during the bottle cap pressing process through the compression deformation of the spring 31 and the threaded engagement of the adjusting nut 29.

[0029] See Figure 8 The clamping mechanism constructs the main frame through the uprights 32 mirrored on both sides of the frame 1. The support frame 33 installed at the top of the uprights 32 provides a mounting base for the clamping cylinders 34. The two sets of mirrored clamping cylinders 34 drive the clamping frame 35 to achieve synchronous opposite movement through the telescopic rod. The clamping blocks 36 distributed in an array on the inner side of the clamping frame 35 use specially made concave grooves on the surface to form a precise positioning with the clamped object. At the same time, a soft protective pad can be attached to the inner side of the clamping block 36 to protect the bottle. The entire mechanism ensures the stable fixation of the workpiece during the processing through the symmetrical clamping method driven by the cylinder. At the same time, the groove design effectively prevents the workpiece from shifting or rotating.

[0030] The mechanism achieves vertical sliding along the upright 32 through the sliding sleeves at both ends of the support frame 33. The crossbar 37 fixed at the top of the upright 32 serves as the mounting base for the adjusting screw 38. The adjusting screw 38 is rotatably connected to the crossbar 37 through bearings. The screw sleeve in the middle of the support frame 33 and the adjusting screw 38 form a threaded transmission pair. When the rotating adjusting wheel 39 drives the adjusting screw 38 to rotate, the screw sleeve drives the entire support frame 33 to perform precise lifting and lowering displacement along the upright 32. The entire adjustment mechanism achieves reliable positioning and flexible adjustment of the working height of the support frame 33 through the self-locking characteristic of the threaded transmission.

[0031] The working principle of this utility model is as follows: In this bottle cap installation device, the bottle cap is initially placed on the bottle body in the preceding process. Then, the bottle body is placed in the corresponding bottle body mounting seat on the conveyor belt 2 to support and limit the bottom of the bottle body. The bottle body is then circulated and transported to the bottom of the bottle cap installation head 3 via the conveyor belt 2. At this time, the clamping cylinder 34 is activated to move the clamping frame 35 inward, and the clamping block 36 installed in the clamping frame 35 is attached to the side wall of the bottle body to limit and clamp the bottle body.

[0032] Start the lifting motor 17, which drives the bottle cap mounting head 3 to move down and place the clamping claw 4 on the outer side of the upper end of the bottle. At this time, start the pull-out cylinder 8 to drive the pull head 7 to move up. In conjunction with the pressure plate 9 and the corresponding shaft, the clamping claw 4 is rotated to clamp the bottle cap on the upper part of the bottle. At the same time, the top block 10 contacts the bottle cap and presses the bottle cap tightly under the action of the spring 31. Then start the rotary motor 24 to drive the rotary shaft 21 to rotate, so that the clamping claw 4 connected to its lower end rotates synchronously, tightening the bottle cap on the upper end of the bottle, thus completing the installation of the bottle cap.

[0033] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
