Description

Technical Field

[0001] The utility model relates to the technical field of capping equipment, in particular to a press-type product capping equipment. Background Art

[0002] Pump caps are widely used in daily chemical products such as shampoo, shower gel, and cosmetics. Users can get the liquid stored in the bottle by pressing the pump cap without unscrewing it, which is convenient to operate, making push-type products popular among consumers.

[0003] The pressure pump cover includes a pipe fitting and a pressure pump head. The pressure pump head includes a retractable pump core, a pressure head and a connecting piece. The connecting piece can be threadedly connected to one end of the bottle body to form a bottle mouth. After the pipe fitting of the pressure pump cover is inserted into the bottle body filled with liquid, the bottle and the cover need to be rotated and closed by a capping device. When the capping device performs the capping operation, it is necessary to first drive the fixing mechanism provided in the capping device to move from top to bottom, so that the fixing mechanism can act on the top of the cover by the principle of negative pressure adsorption, and then drive the cover to rotate by driving the fixing mechanism to achieve the capping of the bottle and the cover. Since the pressure head of the pressure pump head forms the top of the cover and the pressure head can rotate relative to the connecting piece, the existing packaging device cannot tighten the connecting piece to the bottle body by rotating the pressure head. Therefore, the existing packaging device cannot meet the capping requirements of push-type products. Utility Model Content

[0026] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0027] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0028] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0029] refer to Figures 1 to 9 According to a preferred embodiment of the present invention, a push-type product capping device will be described in detail below. The push-type product capping device rotates the pressure pump cap to the bottle body to produce a semi-finished product or a finished product.

[0030] Preferably, the pressure head includes a connecting portion and a pressing portion, and the connecting portion is formed by extending the pressing portion. The connecting portion faces the connecting piece, and one end of the pump core is plugged into the connecting portion. The pressing portion provides a force application site for pressing the pump head. The outer peripheral wall of the connecting portion forms an external thread, and the connecting piece forms a thread groove adapted to the connecting portion. When the pressure head is pressed until the pump core retracts and drives the connecting portion to extend into the thread groove, the pressure head rotates to thread the connecting portion and the connecting piece. In this way, the pump core has no retraction amount, thereby preventing the liquid in the bottle from being pumped out.

[0031] Specifically, the push-type product capping device comprises a conveying mechanism 10 and a device body 20. The conveying mechanism 10 comprises a conveying body 11 and a driving member 12. The device body 20 has a top 21 and a bottom 22 lower than the top 21.

[0032] The conveying body 11 is movably mounted on the bottom 22, and the bottom 22 is used to support the conveying body 11. The bottle body is placed on the upper surface of the conveying body 11. The bottom 22 has a starting end 221 and an ending end 222. The driving member 12 is installed on the bottom 22 in a manner that it can drive the conveying body 11 to be transported from the starting end 221 to the ending end 222, so that the bottle body located on the upper surface of the conveying body 11 is transported from the starting end 221 to the ending end 222.

[0033] In one example, the transmission body 11 is implemented as a transmission belt; and the driving member 12 is implemented as a motor.

[0034] Specifically, the push-type product capping device further includes a cap supply device 30. The cap supply device 30 includes a transmission member 31, a stopper assembly 32 and a cap pushing member 33.

[0035] The transmission member 31 includes a transmission body 311 and a connection body 312. The transmission body 311 is installed on the equipment body 20, and the transmission body 311 extends obliquely to form a high end portion 3111 and a low end portion 3112 lower than the high end portion 3111. The connection body 312 is formed by the end of the low end portion 3112 extending in the horizontal direction away from the high end portion 3111. The transmission body 311 forms a sliding channel 31101 that penetrates up and down along its own extension direction, and the sliding channel 31101 allows the pipe fittings of the pressure pump cover to pass through. The connection body 312 forms a cover drop channel 31201 that is connected to the sliding channel 31101. The pressure pump cover clamped to the transmission body 311 moves from the high end portion 3111 through the low end portion 3112 into the cover drop channel 31201 under the action of gravity.

[0036] The stopper assembly 32 includes two stoppers 321 and two reset members 322, wherein the reset members 322 are configured to be elastically deformable. The two stoppers 321 are arranged opposite to each other and are both movably mounted on the connecting body 312. When the pressure pump cover moves from the sliding channel 31101 to the cover drop channel 31201, the two stoppers 321 block the pressure pump cover from moving vertically downward. The two reset members 322 are respectively mounted between the two stoppers 321 and the connecting body 312. The stoppers 321 are configured to be able to move after being pressurized to avoid the space allowing the pressure pump cover to move downward and squeeze the reset members 322 to be elastically deformed. The cover pusher 33 is arranged above the cover drop channel 31201, and the cover pusher 33 can extend vertically and extend into the cover drop channel 31201 or retract vertically and withdraw from the cover drop channel 31201.

[0037] When the bottle body transported by the conveying mechanism 10 moves to the bottom of the cover-dropping channel 31201, the cover-pushing member 33 extends to press down the pressure pump cover in the cover-dropping channel 31201, and the stopper 321 moves under pressure to make way for the pressure pump cover to move out of the cover-dropping channel 31201, and then the pressure pump cover is plugged into the bottle body in the manner of a tube being inserted into a bottle under the action of gravity; then the cover-pushing member 33 retracts, and the stopper 321 is reset under the action of the elastic restoring force of the reset member 322, and the cycle continues.

[0038] In one example, the return member 322 is implemented to include a spring; and the cover pushing member 33 is implemented to include a cylinder.

[0039] In one embodiment, the two stoppers 321 are pivotally mounted on the connecting body 312. When the cover pusher 33 is extended to press down the pump cover retained in the cover drop channel 31201, the ends of the two stoppers 321 that are close to each other move away from each other to allow the pump cover to fall.

[0040] As a deformable device, the stopper 321 forms a pressure wall 3211, and the pressure wall 3211 extends obliquely downward. The two stoppers 321 are both slidably mounted on the connecting body 312 and the pressure walls 3211 formed by each of them remain relative to each other, and the two stoppers 321 are configured to be able to move away from or approach each other. The angle between the movement trajectory formed by the stopper 321 approaching the relative stopper 321 and the extension direction of the pressure wall 3211 formed by itself is an obtuse angle. When the push cover member 33 is extended to press down the pressure pump cover retained in the cover drop channel 31201, the two stoppers 321 are forced to move away from each other in the horizontal direction to allow the pressure pump cover to fall.

[0041] Furthermore, the cap supply device 30 further comprises a limiting mechanism 34. The limiting mechanism 34 comprises a first limiting member 341.

[0042] The first limiting member 341 is installed on the equipment body 20, and the first limiting member 341 is configured to be able to extend and retract in a direction perpendicular to the conveying direction of the conveying body 11. The first limiting member 341 is used to control whether the bottle body located directly below the cover-dropping channel 31201 continues to move along the conveying direction of the conveying body 11, so that when the bottle body moves to the bottom of the cover-dropping channel 31201, the first limiting member 341 blocks the bottle body from continuing to move toward the end portion 222, so that each bottle body can be inserted with a pressure pump cover. After the pressure pump cover is inserted into the bottle body directly below the cover-dropping channel 31201, the first limiting member 341 retracts, so that the bottle body with the pressure pump cover inserted can continue to be processed later.

[0043] In one example, the first limiting member 341 is implemented to include a cylinder.

[0044] Preferably, the limiting mechanism 34 further includes a second limiting member 342. The second limiting member 342 is mounted on the device body 20, and the second limiting member 342 is configured to be able to extend and retract in a direction perpendicular to the conveying direction of the conveying body 11. The second limiting member 342 is used to control whether the bottle body moving along the conveying direction of the conveying body 11 moves to the bottom of the cover drop channel 31201. When a bottle body is arranged directly under the cover drop channel 31201, the second limiting member 342 remains extended to prevent the remaining bottles from pushing the bottle body directly under the cover drop channel 31201 and causing the position of the bottle body directly under the cover drop channel 31201 to shift, thereby ensuring that the pressure pump cover can be smoothly inserted into the bottle body directly under the cover drop channel 31201. After the bottle body directly under the cover-dropping channel 31201 moves away, the first limiting member 341 extends and the second limiting member 342 retracts, so that the subsequent bottle body moves to the directly under the cover-dropping channel 31201 .

[0045] In one example, the second limiting member 342 is implemented as a cylinder.

[0046] Furthermore, the push-type product capping device further comprises a capping device 40. The capping device 40 is adjacent to the cap supplying device 30, and the capping device 40 is used to rotate and cap the pump cap inserted into the bottle body with the bottle body.

[0047] Specifically, the capping device 40 includes a first bottle holding mechanism 41 and a capping mechanism 42. The first bottle holding mechanism 41 includes two first bottle holding assemblies 411, both of which are installed on the device body 20 and are respectively arranged on opposite sides of the conveying body 11. The first bottle holding mechanism 41 is used to clamp the bottle body conveyed between the two first bottle holding assemblies 411. The capping mechanism 42 is installed on the top 21, and is used to rotate and cap the bottle body clamped by the first bottle holding mechanism 41 with the pressure pump cover inserted into the bottle body.

[0048] That is, when the bottle body with the pump cover inserted is conveyed by the conveying mechanism 10 to between the two first bottle holding assemblies 411, the two first bottle holding assemblies 411 clamp the bottle body, and then the capping mechanism 42 operates to rotate and cap the pump cover on the bottle body. Based on the limiting effect of the first bottle holding mechanism 41 on the bottle body, the bottle body cannot rotate synchronously with the pump cover driven by the capping mechanism 42, so the pump cover can be rotated and capped on the bottle body to produce a semi-finished product or a finished product.

[0049] Preferably, the first bottle holding assembly 411 includes a first bottle holding member 4111 and a first belt shifting member 4112. The first belt shifting member 4112 is mounted on the device body 20, and the first bottle holding member 4111 is drivingly connected to the first belt shifting member 4112. The first belt shifting member 4112 is capable of driving the first bottle holding member 4111 connected to itself to approach or move away from the first bottle holding member 4111 along a horizontal direction perpendicular to the conveying direction of the conveying body 11, so that the two first bottle holding members 4111 clamp the bottle body located between the two first bottle holding members 4111.

[0050] Preferably, the first bottle holding member 4111 is made of a flexible material, such as a sponge. In this way, when the first bottle holding member 4111 made of a flexible material clamps the bottle body, the first bottle holding member 4111 itself can absorb part of the clamping force and deform, thereby reducing the stress of the first bottle holding assembly 411 on the bottle body and making the first bottle holding member 4111 fit the outer wall of the bottle body, so that the bottle body is evenly stressed and mechanical damage caused by clamping is avoided. It is worth mentioning that the first bottle holding member 4111 made of a flexible material can be deformed when clamping the bottle body, so the first bottle holding mechanism 41 can clamp bottles of different thicknesses.

[0051] In one example, the first belt shifter 4112 is implemented as a cylinder.

[0052] Specifically, the capping mechanism 42 includes a first driving member 421 and at least one rotary cover assembly 422. The rotary cover assembly 422 includes at least one rotary cover component 4221 and a first driving member 4222. The rotary cover component 4221 is mounted on the first driving member 4222, and the first driving member 4222 is connected to the first driving member 421 in a manner that can drive the rotary cover component 4221 to rotate along a horizontal plane. The first driving member 421 is mounted on the top 21 of the device body 20. The first driving member 421 drives the rotary cover component 4221 to approach or move away from the pressure pump cover inserted into the bottle body clamped by the first bottle holding mechanism 41 through the first driving member 4222. The first driving member 4222 is configured to drive the rotating cover member 4221 to rotate when the first driving member 421 drives the rotating cover assembly 422 to move until the rotating cover member 4221 contacts the connecting member, so that the rotating cover member 4221 drives the pressure pump cover to rotate, so that the pressure pump cover rotates and covers the bottle body.

[0053] In one embodiment, the height of the rotating cover member 4221 corresponds to the height of the connecting member of the pressure pump cover inserted into the bottle body clamped by the first bottle holding mechanism 41. The first driving member 421 is used to drive the rotating cover assembly 422 to approach or move away from the connecting member in a horizontal direction perpendicular to the conveying direction of the conveying body 11. When the first driving member 421 drives the rotating cover member 4221 to move to the side wall of the rotating cover member 4221 and the side wall of the connecting member through the first driving member 4222, the rotating cover member 4221 driven by the first driving member 4222 drives the pressure pump cover to rotate under the action of friction, so that the pressure pump cover rotates and covers the bottle body.

[0054] As a deformable structure, the outer peripheral wall of the connecting member is spaced apart to form a plurality of vertical grooves, and the side wall of the rotating cover member 4221 is spaced apart to form a plurality of convex strips, which extend vertically. The first driving member 421 is used to drive the rotating cover assembly 422 to vertically approach or move away from the connecting member of the pressure pump cover inserted into the bottle body clamped by the first bottle holding mechanism 41, and when the first driving member 421 is used to drive the rotating cover assembly 422 to vertically approach the connecting member, part of the convex strips formed by the rotating cover member 4221 are inserted into the vertical grooves, so that the rotating cover member 4221 driven by the first driving member 4222 drives the pressure pump cover to rotate through the cooperation of the convex strips and the vertical grooves.

[0055] In one example, the first driving member 421 is implemented to include a cylinder; and the rotating cover 4221 is implemented to include a motor.

[0056] Preferably, the capping mechanism 42 is provided with two capping assemblies 422, which are spaced apart around the bottle body clamped by the first bottle holding mechanism 41, so that a plurality of capping assemblies 422 can simultaneously drive the pump cap to rotate, thereby speeding up the capping speed of the bottle and the cap.

[0057] It can be understood by those skilled in the art that when the connection portion of the pressure head extends into the threaded groove and is threadedly connected to the connecting piece, the pump core is contracted, and the pressure pump cover is in a contracted state. When the connection portion of the pressure head extends out of the threaded groove, the pump core is opened, and the pressure pump cover is in an expanded state. In this way, if the capping device 40 rotates and covers the bottle body with the pressure pump cover in the contracted state, a finished product is produced, and if the capping device 40 rotates and covers the bottle body with the pressure pump cover in the expanded state, a semi-finished product is produced.

[0058] Furthermore, the push-type product capping device further includes a pump retracting device 50. The pump retracting device 50 is adjacent to the capping device 40 and is used to retract the pump of the semi-finished product produced by the capping device 40. Since liquid leakage may occur during the transportation of the semi-finished product, the pump retracting device 50 retracts the pump cover to prevent liquid leakage.

[0059] Specifically, the pump collecting device 50 includes a second bottle holding mechanism 51 and a pump collecting mechanism 52. The second bottle holding mechanism 51 includes two second bottle holding assemblies 511, both of which are installed on the device body 20 and are respectively arranged on both sides of the conveying body 11. The two second bottle holding assemblies 511 are used to clamp and place the semi-finished bottle body held by the first bottle holding mechanism 41 and continuously transported to the end end 222 between the two second bottle holding assemblies 511. The pump collecting mechanism 52 includes a pump collecting assembly 521 and a belt rotating member 522, the pump collecting assembly 521 is installed on the top 21, and the belt rotating member 522 is drivingly connected to the pump collecting assembly 521. The pump collecting assembly 521 drives the belt rotating member 522 to press down the pressure head of the semi-finished product clamped by the second bottle holding mechanism 51, and drives the belt rotating member 522 to rotate when the connecting portion is inserted into the thread groove so that the belt rotating member 522 drives the pressure head to be threadedly connected with the connecting member.

[0060] That is to say, when the semi-finished product is conveyed by the conveying mechanism 10 to between the two second bottle holding assemblies 511, the second bottle holding mechanism 51 clamps the semi-finished product; then the pump collecting assembly 521 drives the belt rotating member 522 to move downward to press the pressure head part into the threaded groove formed by the connecting member, and the pump collecting assembly 521 drives the pressure head to rotate through the belt rotating member 522. Based on the limiting effect of the second bottle holding mechanism 51 on the bottle body, the bottle body and the connecting member cannot rotate synchronously with the pressure head driven by the pump collecting mechanism 52, so the pressure head can be threadedly connected to the connecting member, and the pump core is contracted without compression. After completing the pump collecting operation, the second bottle holding mechanism 51 releases the product, and the pump collecting assembly 521 drives the belt rotating member 522 to move upward to facilitate product unloading.

[0061] Preferably, the second bottle holding assembly 511 includes a second bottle holding member 5111 and a second belt shifting member 5112. The second belt shifting member 5112 is mounted on the device body 20, and the second bottle holding member 5111 is drivingly connected to the second belt shifting member 5112. The second belt shifting member 5112 can drive the second bottle holding member 5111 connected to it to approach or move away from the second bottle holding member 5111 along a horizontal direction perpendicular to the conveying direction of the conveying body 11, so that the two second bottle holding members 5111 can clamp the semi-finished bottle body.

[0062] Preferably, the second bottle holding member 5111 is made of a flexible material, such as a sponge. In this way, when the second bottle holding member 5111 made of a flexible material clamps the bottle, the second bottle holding member 5111 itself can absorb part of the clamping force and deform, thereby reducing the stress of the second bottle holding assembly 511 on the bottle and making the second bottle holding member 5111 fit the outer wall of the bottle, so that the force on the bottle is evenly applied, thereby avoiding mechanical damage to the bottle caused by clamping. It is worth mentioning that the second bottle holding member 5111 made of a flexible material can be deformed when clamping the bottle, so the second bottle holding member 5111 can clamp bottles of different thicknesses.

[0063] In one example, the second belt shifter 5112 is implemented as a cylinder.

[0064] Specifically, the pump assembly 521 includes a pressing member 5211 and a tightening member 5212. The tightening member 5212 is connected to the pressing member 5211. Either the pressing member 5211 or the tightening member 5212 is connected to the belt rotating member 522, and the other is installed on the device body 20. The pressing member 5211 is used to drive the belt rotating member 522 to move vertically, and the tightening member 5212 is used to rotate the belt rotating member 522.

[0065] In one embodiment, the belt rotating member 522 is implemented as a turntable. The pressing member 5211 drives the belt rotating member 522 to press the pressure head, and then the turntable driven by the tightening member 5212 drives the pressure head to be threadedly connected with the connecting member through the friction between the pressing part and the turntable.

[0066] In a modified embodiment, the belt rotating member 522 is implemented as a pneumatic clamp, which fixes the pressing part by clamping, and then the pump assembly 521 drives the pressure head to be tightened to the connecting member through the belt rotating member 522.

[0067] In another variant embodiment, the belt rotating member 522 is implemented as a suction cup, and the suction cup fixes the pressing part by negative pressure adsorption, and then the pump assembly 521 drives the pressure head to be tightened to the connecting member through the belt rotating member 522.

[0068] Compared with the first embodiment, the two modified embodiments can effectively avoid the phenomenon of the belt rotating member 522 idling due to insufficient friction between the belt rotating member 522 and the pressure head, and ensure that the pressure head can be tightened on the thread groove of the connecting member.

[0069] In one example, the pressing member 5211 is implemented as a cylinder, and the tightening member 5212 is implemented to include a motor.

[0070] Furthermore, the push-type product capping device further includes a quantity limiting unit 60 . The quantity limiting unit 60 is disposed between the capping device 40 and the cap supplying device 30 , and is used to control the passage of the bottles conveyed by the conveying mechanism 10 .

[0071] The limiting unit 60 includes an identification member 61 and a blocking member 62. The blocking member 62 includes a first blocking component 621 and a second blocking component 622. The first blocking component 621, the identification member 61 and the second blocking component 622 are installed on the device body 20 at intervals. The first blocking component 621 and the second blocking component 622 are configured to be able to extend and retract in a direction perpendicular to the conveying direction of the conveying body 11.

[0072] The identification member 61 is used to sense whether the bottle body with the pressure pump cap inserted between the first blocking component 621 and the second blocking component 622 has been removed. The first blocking component 621 and the second blocking component 622 are controllably connected to the controller. The capping device 40 and the identification member 61 are both communicatively connected to the controller. After the capping device 40 completes the capping operation, the first blocking component 621 retracts and the second blocking component 622 extends, the first blocking component 621 makes room for the bottle body with the pressure pump cap inserted that is closest to the capping device 40 to move toward the capping device 40, and the second blocking component 622 blocks the subsequent bottle body with the pressure pump cap inserted from moving forward. After the bottle body with the pressure pump cap inserted that is closest to the capping device 40 moves into position, the first blocking component 621 extends and the second blocking component 622 retracts, so that the subsequent bottle body with the pressure pump cap inserted can approach the capping device 40, thereby realizing that the capping device 40 can cap the bottles with the pressure pump cap inserted one by one without interrupting the operation of the conveying mechanism 10.

[0073] In one example, the first blocking assembly 621 and the second blocking assembly 622 are both implemented as cylinders, and the identification element 61 is implemented as a sensor.

[0074] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
