A clamping and fixing device for blister machine surface processing

Abstract

This invention relates to the field of blister packaging machine technology and discloses a clamping and fixing device for surface processing of blister packaging machines. The device includes a mounting block, with an activation mechanism fixedly installed in the center of the inner cavity of the mounting block. Retraction rods are fixedly installed on both the left and right sides of the mounting block, and a compression rod is fixedly installed on the top left side of the retraction rod. During operation, the compression rod, as the retraction rod contracts, comes into close contact with the side of the bottle to be sealed. At this time, a second switch is activated by pressing, coordinating with a movable wheel to rotate the cylinder, causing the protrusion to fit against the outer surface of the bottle to be sealed. Simultaneously, the telescopic block automatically moves to the right under the elastic force of the compression spring in the inner cavity, causing the arc-shaped block to extend. This prevents the bottle from moving upwards if the sealing mechanism adheres to the bottle opening during sealing, thus reducing the accident rate.

Description

Technical Field

[0001] This invention relates to the field of blister packaging machine technology, specifically to a clamping and fixing device for surface processing of blister packaging machines. Background Technology

[0002] With the development of the times, all walks of life have undergone tremendous changes compared to the past. For example, in the past, merchants mostly used baskets or boxes to package their products for easy preservation. Nowadays, products such as detachable sealing bottles have emerged. These products are lightweight and quick to use. At the same time, in order to improve the shelf life of products, a blister packing machine has also appeared. It seals the bottle opening by pressing and melting plastic or aluminum foil, thereby extending the shelf life of the products inside the bottle.

[0003] During the sealing process of bottle openings, most production machines use mechanical conveyor belts to transport goods. Compared to rubber conveyor belts, mechanical conveyor belts are more stable. As a result, many manufacturers, in order to save costs, only install a general hollow ring structure on the conveyor belt to fix the goods on top of the conveyor belt. Therefore, when the machine suddenly stops or vibrates, the bottles on the conveyor belt are prone to tilting and falling, causing the products inside the bottles to fall out, reducing production efficiency. Sometimes, the sealing mechanism can stick to the top of the bottle, so after the sealing mechanism finishes its work, it may carry the bottle upwards, eventually causing the bottle to fall and damage the machine. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a clamping and fixing device for surface processing of blister pack machines. It has the advantages of effectively clamping and fixing the packaging bottle according to its size during transportation and preventing the packaging bottle from sticking to the sealing mechanism. This solves the problems that general merchants cannot reasonably and effectively fix packaging bottles of different sizes and cannot avoid the packaging bottle sticking to the sealing mechanism.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned purpose of effectively clamping and fixing the packaging bottle according to its size and preventing the packaging bottle from sticking to the sealing mechanism during transportation, the present invention provides the following technical solution: a clamping and fixing device for surface processing of a blister pack machine, comprising a mounting block, an actuation mechanism fixedly installed in the middle of the inner cavity of the mounting block, retraction rods fixedly installed on both the left and right sides of the mounting block, a pressing rod fixedly installed on the top of the left side of the retraction rod, a limit block fixedly installed on the top of the pressing rod, and a coding mechanism fixedly installed in the middle of the right side of the pressing rod.

[0008] Preferably, the starting mechanism includes a buffer groove, a switch is fixedly installed at the bottom of the inner cavity of the buffer groove, a buffer spring is fixedly installed in the inner cavity of the buffer groove, a connecting block is movably installed at the top of the inner cavity of the buffer groove, a bottom rod is fixedly installed at the bottom of the connecting block, and a top plate is fixedly installed at the top of the connecting block. The diameter of the connecting block matches the diameter of the inner cavity of the buffer groove. The bottom of the connecting block is fixedly connected to the bottom of the inner cavity of the buffer groove through the buffer spring. The bottom rod is located directly above the switch, so that when the packaging bottle to be sealed is placed on the top plate, the top plate moves downward under the gravity of the packaging bottle, thereby pushing the connecting block downward, so that the bottom rod presses down to start the switch.

[0009] Preferably, a retraction spring is fixedly installed in the inner cavity of the retraction rod, a connecting rope is fixedly connected to the middle of the inner cavity of the retraction rod, a control block is fixedly installed on the right side of the retraction rod, the middle of the left side of the inner cavity of the retraction rod is fixedly connected to the inner cavity of the control block through the connecting rope, the control block is electrically connected to a switch through a wire, and the retraction rods are evenly distributed on the outer surface of the mounting block. Thus, when the switch is activated, the control block activates the retraction connecting rope, thereby driving the retraction rods to retract inward.

[0010] Preferably, an extension rod is movably installed inside the extrusion rod, and a spool is fixedly installed on the left side of the bottom of the extension rod. A groove is opened on the left side of the extrusion rod's inner cavity, and a first tooth is fixedly installed at the bottom of the groove. A second switch is fixedly installed in the middle of the right side of the extrusion rod, and a slide is opened in the middle of the second switch. A second tooth is fixedly installed on one side of the slide's inner cavity. The shape of the outer surface of the spool matches the shape of the first tooth. The extension rod is electrically connected to the second switch via a wire. The right side of the second switch extends out of the right side of the extrusion rod. Thus, when the extrusion rod contacts the side of the packaging bottle, the packaging bottle presses to activate the second switch, thereby controlling the extension rod to move automatically upward. At the same time, the first tooth drives the spool to rotate counterclockwise.

[0011] Preferably, a telescopic block is fixedly installed in the inner cavity of the limiting block, a compression spring is fixedly installed in the middle of the inner cavity of the telescopic block, an arc-shaped block is fixedly installed on the right side of the telescopic block, and a connecting rope two is fixedly connected to the right side of the inner cavity of the telescopic block. The arc-shaped block is made of synthetic rubber. The right side of the inner cavity of the telescopic block is fixedly connected to the outer surface of the spool through the connecting rope two. Thus, when the extension rod moves upward, the spool rotates counterclockwise, causing the connecting rope two to loosen, resulting in the telescopic block automatically moving to the right under the elastic force of the compression spring in the inner cavity.

[0012] Preferably, a strip-shaped groove is provided in the middle of the right side of the extrusion rod. An ink pad is fixedly installed at the rear of the inner cavity of the strip-shaped groove. A cylinder is movably installed in the middle of the inner cavity of the strip-shaped groove. A central shaft is fixedly installed in the middle of the cylinder. A movable wheel is fixedly installed at the bottom of the central shaft. A protrusion is fixedly installed at the rear of the cylinder. The shape and size of the outer surface of the movable wheel match the shape and size of the second gear. Thus, when the second switch is pressed to the left to start, the second gear drives the movable wheel to rotate clockwise, thereby driving the central shaft and the cylinder to rotate clockwise, so that the protrusion rotates 90 degrees clockwise. This makes it easier for the device to print the label on the outer surface of the packaging bottle when extruding and fixing the packaging bottle.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a clamping and fixing device for surface processing of blister pack machines, which has the following beneficial effects:

[0015] 1. This blister packaging machine's surface processing clamping and fixing device, through the setting of a base rod and a control block, when the device is working, after the sealed packaging bottle is placed on the top plate, under the action of the bottle's gravity, the top plate and connecting block move down, causing the base rod at the bottom of the connecting block to move down and press the start switch one, thereby activating the control block, causing the control block to rotate and retract the connecting rope one, thereby driving the retraction rod fixedly connected to the control block through the connecting rope one to retract inward, making it easier to fix the packaging bottle on the top of the top plate. Compared with general fixing devices, this device not only does not require manual operation for installation, but also can automatically adjust the diameter of the top plate after automatic start, so as to place packaging bottles of different diameters while better fixing the packaging bottles, thus improving the usability of the device.

[0016] 2. The clamping and fixing device for surface processing of this blister pack machine, through switch two and the arc block, ensures that during operation, the extrusion rod, along with the contraction rod, makes close contact with the side of the packaging bottle to be sealed. At this time, switch two is activated by pressing under the extrusion action, which, together with the movable wheel, drives the cylinder to rotate, making the protrusion fit against the outer surface of the packaging bottle to be sealed. Simultaneously, switch two activates the extension plate to move upward. Taking advantage of the fact that the diameter of the top and middle of most packaging bottles is different, when the extension plate moves to the point where the diameter of the middle and top of the packaging bottle is different, the telescopic block automatically moves to the right under the elastic force of the extrusion spring in the inner cavity, causing the arc block to extend. This prevents the packaging bottle from moving upward if the sealing mechanism sticks to the bottle opening during sealing, causing the packaging bottle to rise and move. This reduces the accident rate. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see Figure 1-3A clamping and fixing device for surface processing of blister packs includes a mounting block 1. An actuation mechanism 2 is fixedly installed in the middle of the inner cavity of the mounting block 1. The actuation mechanism 2 includes a buffer groove 201. A switch 202 is fixedly installed at the bottom of the inner cavity of the buffer groove 201. A buffer spring 203 is fixedly installed in the inner cavity of the buffer groove 201. A connecting block 204 is movably installed at the top of the inner cavity of the buffer groove 201. A bottom rod 205 is fixedly installed at the bottom of the connecting block 204. A top plate 206 is fixedly installed at the top of the connecting block 204. The diameter of the connecting block 204 matches the diameter of the inner cavity of the buffer groove 201. The bottom of the connecting block 204 is fixedly connected to the bottom of the inner cavity of the buffer groove 201 via the buffer spring 203. The bottom rod 205 is positioned directly above the switch 202. Therefore, when the packaging bottle to be sealed is placed on the top plate 206, the top plate 206 tilts downwards under the weight of the packaging bottle. The movement pushes the connecting block 204 downward, causing the bottom rod 205 to press down and activate the switch 202. Retractable rods 3 are fixedly installed on both the left and right sides of the mounting block 1. A retraction spring 301 is fixedly installed inside the retractable rod 3. A connecting rope 302 is fixedly connected to the middle of the inner cavity of the retractable rod 3. A control block 303 is fixedly installed on the right side of the retractable rod 3. The middle of the left side of the inner cavity of the retractable rod 3 is fixedly connected to the inner cavity of the control block 303 via the connecting rope 302. The control block 303 is electrically connected to the switch 202 via a wire. The retractable rods 3 are evenly distributed on the outer surface of the mounting block 1. When the switch 202 is activated, the control block 303 activates the retractable connecting rope 302, thereby causing the retractable rods 3 to retract inward. A pressing rod 4 is fixedly installed on the top of the left side of the retractable rod 3. A limit block 5 is fixedly installed on the top of the pressing rod 4. A marking mechanism 6 is fixedly installed in the middle of the right side of the pressing rod 4.

[0027] Working principle: When the device is working, the bottle to be sealed is placed on the top plate 206, causing the top plate 206 and the connecting block 204 fixedly installed at the bottom of the top plate 206 to move downwards under the weight of the bottle. The diameter of the connecting block 204 matches the diameter of the inner cavity of the buffer groove 201. The bottom of the connecting block 204 is fixedly connected to the bottom of the inner cavity of the buffer groove 201 via a buffer spring 203. The bottom rod 205 is positioned directly above the switch 202, thus the bottom rod 205 at the bottom of the connecting block 204 moves downwards to press the switch. A switch 202 is electrically connected to a control block 303 via a wire. The middle of the left side of the inner cavity of the retractable rod 3 is fixedly connected to the inner cavity of the control block 303 via a connecting rope 302. When the control block 303 is activated, it rotates to retract the connecting rope 302, thereby causing the retractable rod 3, which is fixedly connected to the control block 303 via the connecting rope 302, to retract inward until the diameter of the left and right retractable rods 3 matches the diameter of the bottom of the packaging bottle to be sealed, which facilitates fixing the packaging bottle on the top of the top plate 206.

[0028] In summary, compared with general fixing devices, the clamping and fixing equipment for surface processing of the blister pack machine not only does not require manual operation and installation, but also automatically starts when the packaging bottle to be sealed is placed on the top plate 206. At the same time, the device can independently adjust the diameter between the left and right shrink rods 3, which makes it easier to place packaging bottles of different diameters, achieve better packaging bottle fixing effect, and improve the usability of the device.

[0029] Example 2

[0030] Please see Figure 1 , Figure 4 , Figure 5 , Figure 6A clamping and fixing device for surface processing of a blister pack machine includes a mounting block 1. An actuating mechanism 2 is fixedly installed in the center of the inner cavity of the mounting block 1. Retraction rods 3 are fixedly installed on both the left and right sides of the mounting block 1. An extrusion rod 4 is fixedly installed on the top left side of the retraction rod 3. An extension rod 401 is movably installed in the inner cavity of the extrusion rod 4. A threaded wheel 402 is fixedly installed on the left side of the bottom of the extension rod 401. A groove 403 is formed on the left side of the inner cavity of the extrusion rod 4. A gear 404 is fixedly installed at the bottom of the groove 403. A switch 405 is fixedly installed in the center of the right side of the extrusion rod 4. A slide 406 is formed in the center of the switch 405. A gear 404 is fixedly installed on one side of the inner cavity of the slide 406. The outer surface shape of the gear 407 and the reel 402 matches the shape of the gear 404. The extension rod 401 is electrically connected to the switch 405 via a wire. The right side of the switch 405 extends beyond the right side of the extrusion rod 4. When the extrusion rod 4 contacts the side of the packaging bottle, the bottle presses to activate the switch 405, thereby controlling the extension rod 401 to move automatically upward. Simultaneously, the gear 404 drives the reel 402 to rotate counterclockwise. A limit block 5 is fixedly installed on the top of the extrusion rod 4. A telescopic block 501 is fixedly installed inside the limit block 5. A compression spring 502 is fixedly installed in the middle of the telescopic block 501. An arc-shaped spring is fixedly installed on the right side of the telescopic block 501. The right side of the inner cavity of the arc-shaped block 503 and the telescopic block 501 is fixedly connected to the connecting rope 504. The arc-shaped block 503 is made of synthetic rubber. The right side of the inner cavity of the telescopic block 501 is fixedly connected to the outer surface of the spool 402 through the connecting rope 504. When the extension rod 401 moves upward, the spool 402 rotates counterclockwise, causing the connecting rope 504 to loosen. This causes the telescopic block 501 to move automatically to the right under the elastic force of the inner cavity compression spring 502. A marking mechanism 6 is fixedly installed in the middle of the right side of the compression rod 4. A strip groove 601 is opened in the middle of the right side of the compression rod 4. An ink pad 602 is fixedly installed at the rear of the inner cavity of the strip groove 601. A cylinder 603 is movably installed in the middle of the inner cavity of 601. A central shaft 604 is fixedly installed in the middle of the cylinder 603. A movable wheel 605 is fixedly installed at the bottom of the central shaft 604. A protrusion 606 is fixedly installed at the rear of the cylinder 603. The shape and size of the outer surface of the movable wheel 605 match the shape and size of the second gear 407. When the second switch 405 is pressed to the left to start, the second gear 407 drives the movable wheel 605 to rotate clockwise, thereby driving the central shaft 604 and the cylinder 603 to rotate clockwise, so that the protrusion 606 rotates 90 degrees clockwise. This makes it easier for the device to print the label on the surface of the protrusion 606 onto the outer surface of the packaging bottle when squeezing and fixing the packaging bottle.

[0031] Working Principle: When the device is working, the extrusion rod 4, along with the contraction rod 3, comes into close contact with the side of the bottle to be sealed. The right side of the extrusion rod 4 extends from the right side of the switch 405. A slide 406 is provided in the middle of the switch 405, and a tooth 407 is fixedly installed on one side of the inner cavity of the slide 406. The shape and size of the outer surface of the movable wheel 605 match the shape and size of the tooth 407. Therefore, when the switch 405 is pressed and activated by the extrusion rod 4 and the bottle to be sealed, the switch 405 moves to the left, causing the movable wheel 605 to rotate clockwise via the tooth 407. This further drives the central shaft 604 and the cylinder 603 to rotate 90 degrees clockwise, causing the protrusion 606 behind the cylinder 603 to rotate 90 degrees clockwise and come into contact with the outer surface of the bottle to be sealed. This achieves the effect of printing the label on the protrusion 606 onto the outer surface of the bottle when the extrusion rod 4 contacts the outer surface of the bottle. Simultaneously, switch 405 is activated, causing the extension rod 401, which is electrically connected to switch 405, to move upward within the compression rod 4. Because the diameter of the top and middle of most packaging bottles is different, the spool 402 on the left side of the bottom of the extension rod 401 is fixedly connected to the right side of the inner cavity of the telescopic block 501 via connecting rope 504. The shape of the outer surface of the spool 402 matches the shape of the first tooth 404 in the groove 403 on the right side of the inner cavity of the compression rod 4. Therefore, when the extension rod 401 moves upward to the point where the diameter of the middle and top of the packaging bottle is different, the spool 402 rotates counterclockwise under the engagement of the first tooth 404, causing the connecting rope 504 to be in a relaxed state. As a result, the telescopic block 501 automatically moves to the right under the elastic force of the compression spring 502 in the inner cavity, causing the arc block 503 to extend. This results in the diameter between the relative arc blocks 503 being smaller than the middle diameter of the packaging bottle and larger than the top diameter of the packaging bottle.

[0032] In summary, this blister pack machine's surface processing clamping and fixing device can automatically print labels on the packaging bottles while sealing them. Furthermore, if the sealing mechanism adheres to the bottle opening, causing the bottle to rise and move, the extended telescopic block 501 and arc-shaped block 503 can be used to hold the bottle in place, preventing it from moving upwards and reducing the accident rate. The material properties of the arc-shaped block 503 can also be used to prevent the telescopic block 501 from scratching the bottle when it comes into contact with it.
