Automatic processing technology of hot compress patch

Abstract

This invention relates to the field of heat therapy patch processing technology, specifically an automated processing technology for heat therapy patches. The production and processing of heat therapy patches requires first preparing the heating raw materials, then placing them into a non-woven fabric packaging bag, and finally heat-sealing the non-woven fabric to form a heat therapy unit. The heat therapy unit is then compacted and flattened using a compaction and flattening device, and finally packaged. The compaction and flattening device of this invention uses a compaction plate that moves synchronously with the heat therapy unit to compress and flatten it. The downward pressure on the heat therapy unit gradually increases during the movement of the compaction plate, improving the packaging effect of the heat therapy patch. Furthermore, the baffle plate of the compaction and flattening device can block the heat therapy unit, ensuring that the right side of the heat therapy unit is aligned and preventing left-right position deviations between corresponding front and rear heat therapy units. This solves the problem of poor flatness of heat therapy units in existing heat therapy patch processing methods.

This phenomenon will not only make the hot compress patch packaging unsightly and affect the bagging and boxing of the hot compress patch, but will also cause unevenness during later use. Existing hot compress units are packaged by roller rolling to flatten them.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1 , an automatic processing technology of a hot compress patch, comprising the following steps: step 1, firstly configuring the heating raw materials of the hot compress patch, and storing the heating raw materials for standby use;

[0039] Step 2: Multi-layer lamination of fiber non-woven fabrics to obtain a hot compress patch upper film, hot-pressing and compounding the hot compress patch upper film with hot melt adhesive to obtain a hot compress patch lower film, and then introducing the heating raw material between the stacked hot compress patch upper film and the hot compress patch lower film, and then heat-sealing the hot compress patch upper film and the hot compress patch lower film, and then die-cutting the heat-sealed position to obtain a hot compress unit;

[0040] Step three, carry out weight and quality inspection on the hot compress unit. After passing the inspection, the hot compress unit is transmitted to the packaging station by multiple conveyor belts arranged at equal intervals. The conveyor belt adopts a compaction and leveling device to flatten and extrude the hot compress unit, so that the hot compress unit can be flat and densely packaged later. The packaging station packs the hot compress unit between the upper film and the lower film of the packaging bag, and then cuts the upper film and the lower film of the packaging bag to obtain the hot compress patch. Finally, the hot compress patch is bagged, packaged and stored.

[0041] See also Figure 1-Figure 5 The compacting and leveling device includes a lower support plate 1 arranged at the lower side of the conveyor belt, and a supporting vertical plate 2 is symmetrically installed on the upper side of the lower support plate 1 and located on the outer side of the conveyor belt. A transmission roller 3 and a toggle roller 4 are rotatably installed between the supporting vertical plates 2. The toggle roller 4 and the transmission roller 3 are sequentially arranged in the conveying direction of the conveyor belt. The transmission roller 3 and the toggle roller 4 are both arranged between the upper and lower sides of the conveyor belt and are driven by the conveyor belt wheel of the conveyor belt through a chain. The transmission roller 3 is connected with a compacting part 5 that moves synchronously with the conveyor belt and presses down and level the hot compress unit on the conveyor belt. A blocking plate 6 is arranged on the side of the toggle roller 4 corresponding to the conveying direction of the conveyor belt, and a blocking slider and a blocking slide groove that slide with each other are respectively arranged between the blocking plate 6 and the supporting vertical plate 2. The upper end of the blocking slider is arranged by a downward pressure spring 61 Installed on the upper side wall of the blocking chute, the compaction and flattening device extrude and flatten the hot compress unit in a synchronous movement with the hot compress unit, thereby increasing the packaging effect of the hot compress patch in the later stage. Specifically, the hot compress unit is conveyed from left to right by the conveyor belt, and is blocked by the blocking plate 6 when it is conveyed to the position of the hot compress unit, so that the right side position of the hot compress unit can be aligned, thereby preventing the hot compress units corresponding to the front and rear positions from having left and right position deviations. At this time, the conveyor belt wheel of the conveyor belt drives the driving roller 3 and the driving roller 4 to rotate respectively, and when the driving roller 4 rotates, the blocking plate 6 can be lifted upward, so that the hot compress unit moves to the right side. When the hot compress unit moves to the position of the compaction part 5, the compaction part 5 can extrude and flatten the hot compress unit, and the extruded hot compress unit is transferred to the packaging station by the conveyor belt for packaging.

[0042] See also Figure 1A protective plate 11 is provided on both sides of each of the conveyor belts and at a position where the blocking plate 6 conforms to the conveying direction of the conveyor belt. A conductive plate 12 is provided on both sides of each conveyor belt and at a position where the blocking plate 6 corresponds to the conveying direction of the conveyor belt. The protective plate 11 is a planar structure in the length direction, and the conductive plate 12 is a zigzag structure in the length direction. The protective plate 11 can protect the hot compress unit to prevent the hot compress unit from having a front-to-back position deviation during the conveying process, causing it to fall from the conveyor belt. The zigzag structure of the conductive plate 12 allows the hot compress unit to be guided by the conductive plate 12 before it moves to the blocking plate 6, thereby causing the hot compress unit to shake back and forth, so that the heat-generating material in the hot compress unit is shaken and leveled, thereby increasing the flatness of the subsequent downward pressure on the heat negative unit.

[0043] See also Figure 5-Figure 7 , the toggle roller 4 is provided with a transmission member, the transmission member is provided with a toggle rod 41, and an L-shaped lifting rod 62 is provided on the side of the blocking plate 6. The lifting rod 62 is toggled by the toggle rod 41 to reciprocate up and down. When the toggle roller 4 rotates, the toggle rod 41 will contact the lifting rod 62, so that the lifting rod 62 drives the blocking plate 6 to move upward, and the hot compress unit blocked by the blocking plate 6 can be transmitted to the right. When the toggle rod 41 continues to rotate and separates from the lifting rod 62, the blocking plate 6 returns to the initial position under the action of the downward pressure spring 61. It should be noted that when the length of the hot compress unit is too long, the lifting period of the blocking plate 6 is not enough for the hot compress unit to completely move out of the blocking plate 6. At this time, a roller can be set at the bottom of the blocking plate 6. When the blocking plate 6 is lowered by the downward pressure spring 61, the roller at the bottom of the blocking plate 6 can be pressed on the top of the hot compress unit. The downward pressure of the blocking plate 6 will not affect the transmission of the hot compress unit to the right under the action of the roller.

[0044] See also Figure 7 The transmission member includes an annular groove arranged on the toggle roller 4, an annular telescopic column 42 is sleeved on the outer side of the annular groove, the fixed end of the annular telescopic column 42 is connected to the toggle rod 41, and the inner annular surface of the fixed end of the annular telescopic column 42 is evenly provided with triangular grooves, and the outer side of the annular groove is provided with triangular convex teeth 43 matching the triangular grooves. Since the toggle roller 4 and the transmission roller 3 are synchronously driven by the conveying roller of the conveyor belt, the hot compress unit can be operated synchronously. When the hot compress unit continues to be transmitted from the right side of the blocking plate 6 to the position of the compacting part 5, the compacting part 5 The position may deviate from the left and right position of the hot compress unit, so the annular telescopic column 42 is rotated and adjusted to make the compacting part 5 correspond to the left and right position of the hot compress unit. The specific adjustment step of the annular telescopic column 42 is to press the annular telescopic column 42 inward so that the telescopic end of the annular telescopic column 42 contracts, and the triangular convex tooth 43 in the fixed end of the annular telescopic column 42 is separated from the triangular groove. At this time, the annular telescopic column 42 is rotated by a certain angle, and the external force is removed, so that the triangular convex tooth 43 in the annular telescopic column 42 is locked with the triangular groove again.

[0045] See also Figure 2-Figure 4 , Figure 6 The compacting part 5 includes two driving members 7, which are driven by the two ends of the driving roller 3 and drive the compacting part 5 to reciprocate along the conveying direction of the conveyor belt. A T-shaped slider 51 is installed on the upper end of each driving member 7, and a T-shaped slide 21 that slides with the T-shaped slider 51 is provided on the support vertical plate 2. A return spring 52 is provided between the T-shaped slider 51 and the T-shaped slide 21. A compacting support plate 53 corresponding to the position of the conveyor belt is provided between the two T-shaped sliders 51. The adjacent compacting support plates 53 and the compacting support plates 53 and the T-shaped sliders 51 are connected by compacting connecting rods. An elastic pressing piece is connected to each compacting support plate 53, and a track guide is connected to the upper end of the elastic pressing piece close to the support vertical plate 2. Rod 57, a track plate 58 for guiding the track guide rod 57 is arranged on the support vertical plate 2, the track guide rod 57 cooperates with the track plate 58 so that the elastic pressing member gradually applies downward pressure to the hot compress unit as it moves, and automatically rebounds to the initial height when the elastic pressing member is separated from the hot compress unit, the compacting part 5 can move synchronously with the hot compress unit, and gradually increase the downward pressure on the hot compress unit during the movement, this downward pressing method can increase the flatness of the hot compress unit extrusion, specifically, after the hot compress unit moves to the bottom of the compacting part 5, the transmission roller 3 drives the driving member 7 to move, and the driving member 7 drives the T-shaped slider 51 to move synchronously, so that the track guide rod 57 on the elastic pressing member cooperates with the track plate 58 to press down the hot compress unit.

[0046] Continue reading Figure 2-Figure 4 , Figure 6The track plate 58 is located within the movement range of the track guide rod 57. The two ends of the track plate 58 are horizontal structures, and the middle part of the track plate 58 gradually tilts downward in the conveying direction of the conveyor belt; the elastic pressing member includes a compacting rod 54 that runs through the middle of the compacting support plate 53. The bottom of the compacting rod 54 is an elastic telescopic structure. A retraction spring 55 is installed on the top of the compacting rod 54. The lower end of the retraction spring 55 is connected to the compacting support plate 53. A compacting plate 56 is installed on the telescopic end of the compacting rod 54. A synchronization rod 59 is connected between the upper ends of adjacent compacting rods 54. The upper end of the compacting rod 54 close to the supporting vertical plate 2 is connected to the track guide rod 57. The elastic force of the return spring 52 is greater than the elastic force of the retraction spring 55. Force, in the initial state, the track guide rod 57 is not in contact with the track plate 58, when the track guide rod 57 moves with the compacting rod 54, the track guide rod 57 drives the compacting rod 54 to move along the track of the track plate 58, so that the compacting plate 56 at the bottom of the compacting rod 54 squeezes the hot compress unit with gradually increasing force, when the track guide rod 57 continues to move to the right, it will separate from the track plate 58, and the track guide rod 57 moves upward under the action of the retraction spring 55. At this time, the compacting plate 56 is separated from the hot compress unit, thereby not affecting the continued transmission of the hot compress unit, and then the driving member 7 is separated from the transmission roller 3, so that the driving member 7 and the compacting part 5 are restored to their initial positions, and a cycle of squeezing the hot compress unit is performed in this way.

[0047] See also Figure 6 A support plate 22 is provided on one side of the driving roller 3 in the direction of conveying of the conveyor belt. The support plate 22 is installed between the supporting vertical plates 2. The support plate 22 is used to support the compacting plate 56 when it presses down on the hot compress unit.

[0048] Continue reading Figure 6 In this embodiment, the circumference of the conveyor pulley of the conveyor belt is greater than the length of the driving member 7. The driving member 7 is an L-shaped driving rod 71. The lower end of the driving rod 71 is a rack structure. The transmission roller 3 is provided with incomplete external teeth meshing with the position of the rack structure of the driving rod 71. The rack structure at the lower end of the driving rod 71 moves to the right under the drive of the incomplete teeth of the transmission roller 3. When the notch of the incomplete teeth of the transmission roller 3 corresponds to the driving rod 71, the driving rod 71 will return to the initial position under the action of the return spring 52.

[0049] Example 2

[0050] See also Figure 8-Figure 10In this embodiment, the circumference of the conveyor belt wheel of the conveyor belt is smaller than the length of the driving member 7. Therefore, the structure in embodiment 1 cannot be used to extrude the hot compress unit. In this embodiment, the structures of the driving member 7 and the paddle roller 4 are modified. The driving member 7 is an L-shaped follower rod 72. The lower end of the follower rod 72 is a rack structure. The middle part of the follower rod 72 is an elastic telescopic structure, and the middle part of the follower rod 72 has an upward rebound force. The telescopic force of the return spring 52 is greater than the telescopic force of the follower rod 72. The outer side of the transmission roller 3 is provided with external teeth meshing with the rack structure of the follower rod 72. The lower end of the telescopic structure of the follower rod 72 is provided with a guide round rod 73, and the support vertical plate 2 is provided with a circular guide groove 74 for guiding the guide round rod 73. The circular guide groove 74 is arranged downwardly inclined corresponding to one side of the driving roller 3, and a one-way guide plate 75 is arranged at one end of the downwardly inclined circular guide groove 74. The one-way guide plate 75 can only be turned downward. When specifically set, the one-way guide plate 75 is connected to the circular guide groove 74 by rotation, and the rotating shaft on the one-way guide plate 75 is connected to the circular guide groove 74 by a torsion spring, so that the one-way guide plate 75 is in an initial state. The cam 73 is a substantially parallelogram of the cam 74, and the cam 75 is substantially parallelogram of the cam 74. The cam 73 is a substantially parallelogram of the cam 74, and the cam 75 is substantially parallelogram of the cam 74. The cam 73 is a substantially parallelogram of the cam 74, and the cam 75 is substantially parallelogram of the cam 74. The movable rod 72 has the potential energy of contraction, and the rotation of the transmission roller 3 drives the follower rod 72 to move to the right. When the external teeth on the transmission roller 3 separate from the rack structure of the follower rod 72, the guide round rod 73 moves to the right side of the lower end of the circular guide groove 74 and moves upward under the action of the contraction potential energy of the guide round rod 73. At the same time, the return spring 52 drives the guide round rod 73 to move to the left along the upper side of the circular guide groove 74, and then the guide round rod 73 moves downward on one side of the downward inclined structure of the circular guide groove 74 and moves to the bottom of the one-way guide plate 75, thus completing a cycle of the driving member 7.

[0051] See also Figure 8 The toggle roller 4 includes a transmission gear 44 arranged on its outer side, and a toggle gear 45 is meshed and connected to the top of the transmission gear 44 through a transition gear. The size of the toggle gear 45 is larger than the transmission gear 44. The toggle gear 45 is rotatably connected to the side of the supporting vertical plate 2. The transmission member is arranged at the shaft end of the toggle gear 45, and the transmission member is connected to the toggle rod 41. In this embodiment, the switching frequency of the blocking plate 6 can be reduced by the toggle gear 45, so that the hot compress unit can be transmitted and squeezed flat in sequence.

[0052] The other structures of this embodiment are the same as those in Embodiment 1, and thus will not be described repeatedly in this embodiment.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
