Background

Tape applicators are used to assist the operator in pulling a strip of tape from a roll of tape and accurately applying it to the surface of a target product. Currently, existing manually operated tape applicators typically require two hands to operate. The user needs to manually pull out the head of the tape, unroll the tape, and then apply the tape to the target product. This action needs to be repeated for the next tape application. The adhesive tape applicator has no automatic adhesive tape head starting function and low operation efficiency. In addition, in the existing adhesive tape applicators, when the adhesive tape is applied, pressure and traction are mainly applied to the adhesive tape by the application roller so as to drive the adhesive tape to unwind and advance. That is, there is no mechanism to provide auxiliary power for the advancement of the adhesive tape and to prevent the adhesive tape from coming off the guide after the adhesive tape is unwound until it is applied to the target product, which makes the transfer process of the adhesive tape unstable. Further, according to the existing manual tape applicator, it is general that a user roughly determines a terminal position where the tape is to be applied by visual inspection and then cuts the tape with an additional cutting device, that is, there is no mechanism for automatically determining the terminal position where the tape is applied and cutting the tape on the existing manual tape applicator. Such tape applicators tend to be cumbersome to operate and inaccurate in applying tape. Since there is no automatic starting and cutting device, continuous tape application operation cannot be performed, resulting in low efficiency of tape application; the force applied by the adhesive tape is easily uneven in the process of applying the adhesive tape, and the contact area between the adhesive tape and a target product to which the adhesive tape is applied cannot be ensured; and the tape application position is unstable.

Detailed Description

The structure and operation of the hand-held adhesive tape dispenser according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 and 2 show a hand-held adhesive tape applicator 1 according to the invention as a whole. As shown in fig. 1, the hand-held adhesive tape applicator 1 according to the present invention is divided into two parts, namely: a lower tape application part 100 and an upper tape support part 200. The tape support 200 serves to support the tape roll 201 and enables the tape roll to rotate on the tape support 200 to unwind the tape 202. The tape applicator 100 is used to apply the tape 202 unwound from the tape roll 201 on the tape support 200 to a target product.

As shown in fig. 1 and 2, the adhesive tape applying part 100 includes a support plate 110. The support plate 110 is provided with a tape clamping and synchronizing mechanism 120, a tape applying roller 130, a lateral positioning roller 151, a lateral positioning roller 152, a handle 160, an auxiliary handle 401, and a series of guide members for guiding the tape.

The adhesive tape 202 unwound from the tape roll 201 first passes between the first guide wheel 601 and the second guide wheel 602 and is then guided to the tape clamping and synchronizing mechanism 120, and the adhesive tape leaving the tape clamping and synchronizing mechanism is further guided to the tape application roller 130 and is pressed and applied to the surface of the target product via the tape application roller 130. According to the utility model discloses a sticky tape applicator 1 still is provided with supplementary roller 131. The auxiliary roller is disposed in front of the tape application roller and is connected to the support plate 110. The auxiliary roller 131 can assist the tape applicator in maintaining balance when applying the tape by the tape application roller 130, increasing the stability of the tape application process. Further, when it is desired to make the tape applicator more stable, the auxiliary handle 401 may be held by one hand of the user to assist in maintaining the balance of the tape applicator. In the tape application process, the tape application roller 130 provides power for unwinding and conveying of the tape while pressing the tape and applying the tape onto the surface of the target product.

The tape dispenser according to the present invention is characterized by having a tape clamping and synchronizing mechanism 120. The tape clamping and synchronizing mechanism 120 is used to clamp the tape at a set clamping force and direct the tape forward to the tape applicator roll 130. In addition, the tape clamping and synchronizing mechanism 120 can be driven by the tape application roller 130 to further drive tape advancement.

The structure and operation of the tape clamping and synchronizing mechanism 120 of the tape applicator 1 will be described with reference to the accompanying drawings. As shown in fig. 3 and 4, the tape clamping and synchronizing mechanism 120 has a clamping box 121, an adjusting bolt 122, a first clamping roller 123, a second clamping roller 124, and a manual knob 125. The clamping box 121 is fixedly connected with the support plate 110. The first pinch roller 123 and the second pinch roller 124 are disposed adjacently and in parallel in the pinch case 121, and are engageable with each other and relatively rotatable. The unwound adhesive tape enters through an opening in the upper side of the grip case 121, passes between the first grip roller 123 and the second grip roller 124, and then passes out through an opening in the lower side of the grip case 121. The first and second pinch rollers 123 and 124 apply a preset pinching force to the adhesive tape. The adjusting bolt 122 is provided on a side portion of the pinch cassette 121 parallel to the axial direction of the pinch roller. The rotation of the adjusting bolt 122 can push the second pinch roller 124 to approach the first pinch roller 123 or to be away from the first pinch roller 123, so as to adjust the clamping force, thereby always keeping the adhesive tape in the adhesive tape applying portion 100 at a proper tension during the application process. Specifically, referring to fig. 4, a slider 126 is provided inside the clamping box 121. The sliders 126 are coupled to both ends of the shaft 1241 of the second pinch roller 124. The first side portion 1261 and the second side portion 1262 of the slider 126 are respectively provided in the slide holes 1213 and 1214 on both sides of the clamp box 121 and are slidable in the slide holes 1213 and 1214 in a direction perpendicular to the axial direction of the second clamp roller 124, thereby bringing the second clamp roller 124 into sliding motion. The adjustment bolt 122 is connected to a third side 1263 of the slider 126 perpendicular to the first and second sides by a spring 127. Screwing the adjusting bolt 122 can adjust the pressure exerted by the spring 127 on the slider 126, and thus can adjust the clamping force between the first clamping roller 123 and the second clamping roller 124. A baffle 129 is provided on the opposite side of the clamping box 121 from the support plate 110. The baffle can prevent the sliding block from sliding out of the sliding hole.

The nip rollers of the tape clamping and synchronizing mechanism 120 can be driven by the tape application roller 130. Specifically, as shown in fig. 4, the end of the shaft 132 of the tape application roller 130 is provided with a driving gear 501. The driving gear 501 is coupled with an intermediate gear 502 provided at the side of the grip case 121 through a timing belt 503. The intermediate gear 502 meshes with a drive gear 504. The drive gear 504 is coupled with the shaft 1231 of the first pinch roller 123 to drive the first pinch roller 123 in rotation. The drive gear 501, the intermediate gear 502, the timing belt 503, and the drive gear 504 constitute a transmission mechanism. When the tape is applied to the target product by the tape application roller 130, the rotation of the tape application roller 130 is transmitted to the first pinch roller 123 through the transmission mechanism. Thereby, the first pinch roller 123 obtains an additional driving force. The rotation of the first pinch roller 123 drives the second pinch roller 124 to provide additional power for unwinding and advancing the adhesive tape. In this way, the adhesive tape is pulled not only by the adhesive tape application roller 130 but also by the first pinch roller 123 and the second pinch roller 124, thereby reducing the tensile stress in the adhesive tape between the pinch rollers and the adhesive tape application roller 130. More importantly, the structure can realize automatic starting of the adhesive tape. Specifically, after the tape application is completed once, the tape is cut between the pinch roller and the tape application roller 130, and then the head of the tape needs to be pulled out when the next tape application is performed. According to the above-described structure, when the user needs to perform the next tape application, the user can place the tape application roller 130 on the surface of the target product and roll it on the surface of the target product, thereby rotating the pinch roller. Since the pinch roller applies a certain clamping force to the tape, rotation of the pinch roller causes the tape to move toward the tape application roller. In this way, an automatic start of the adhesive tape can be achieved.

In addition, the tape clamping and synchronizing mechanism 120 includes a manual knob 125. The manual knob 125 is provided on a side of the grip case 121 perpendicular to an axial direction of the grip rollers and connected to one of the grip rollers. In the illustrated embodiment, the manual knob 125 is connected to the first pinch roller 123. Manual rotation of the manual knob 125 can cause the pinch rollers to rotate. The rotation of the first and second pinch rollers 123, 124 can advance the tape sandwiched therebetween in a direction toward the tape application roller 130. In this way, a manual start of the adhesive tape can be achieved.

Since the tape clamping and synchronizing mechanism 120 has the clamping case 121 through which the tape can pass only within the opening range of the clamping case 121, the tape can be prevented from being separated from the pinch roller by restricting the movement of the tape in the axial direction of the pinch roller. Due to the arrangement of the adjusting bolt 122, the clamping force of the clamping roller can be adjusted for different adhesive tapes. And, with the manual knob 125, manual start of the tape can be achieved.

In addition, the tape clamping and synchronizing mechanism 120 has a quick release knob 1212. A quick release knob 1212 is provided on the top of the clamping box 121. Turning the quick release knob 1212 releases the pressure exerted by the spring 127 on the slider 126, thereby causing the first and second pinch rollers 123, 124 to separate. At this time, the adhesive tape can pass freely between the first pinch roller 123 and the second pinch roller 124. This configuration is highly advantageous in the case of a first pass of the adhesive tape through the adhesive tape clamping and synchronizing mechanism. This configuration is particularly advantageous in the case of frequent tape roll replacement.

The adhesive tape dispenser 1 according to the present invention further has a shearing mechanism 170. The structure and operation of the cutting mechanism 170 of the adhesive tape applicator 1 will be described in detail with reference to fig. 5 to 8.

In order to more clearly show the shearing mechanism according to the invention, some parts have been omitted in fig. 5 and 6. The shearing mechanism 170 according to the present invention includes a trigger 171, a first blade 172, a second blade 174, and a linkage mechanism. The trigger 171 is movably connected to the handle 160, and in particular, one end of the trigger 171 is fixed to a first end of the swing link 175. The swing link 175 is coupled to the handle 160 by a pivot shaft 173 and can swing about the pivot shaft. The pivot shaft 173 is fixed to the handle 160. A second end of the rocker 175 is coupled to one end of a linkage 176. The other end of the linkage 176 is connected to the second blade 174. The second blade 174 is coupled to the fixed block 178 by a rotation shaft 179 and is rotatable about the rotation shaft 179. The first blade 172 is fixed to a fixing block 178 by a rotation shaft 179. The fixing block 178 is fixedly connected to the support plate 110. The first blade 172, the second blade 174, and the rotating shaft 179 form a scissors-like structure. The second blade 174 is movable between a blade first position separated from the first blade 172 and a blade second position engaged with the first blade 172 to cut the tape by rotating about a rotation shaft 179. Here, the pivot shaft 173, the swing lever 175, and the link 176 constitute a link mechanism. The trigger 171 is coupled to the second blade 174 via a linkage mechanism, thereby moving the second blade 174 between the first blade position and the second blade position.

When the tape is to be cut, the trigger 171 is pressed toward the handle, so that the swing link 175 swings away from the handle. The swinging of the swing link 175 moves the linkage 176 in the direction of the fixed block 178, thereby causing the blade 174 to rotate about the rotation axis 179 to close with the fixed blade 172, completing the cutting of the tape. Fig. 7 shows a state before the adhesive tape is cut. Fig. 8 shows a state after the adhesive tape is cut. It can also be seen from fig. 8 that the head of tape after being cut is below the tape clamping and synchronizing mechanism 120. At this time, the tape application roller is rolled on the surface of the target product, thereby rotating the first and second pinch rollers 123 and 124, thereby providing an additional driving force for the advance of the tape. The first clamping roller 123 and the second clamping roller 124 can be driven to rotate by manually rotating the manual knob, so that the adhesive tape is manually started.

In addition, referring to fig. 5 and 6, the cutting mechanism 170 further has a reset device 177. In the exemplary embodiment shown, the return device 177 is a return spring. The reset device 177 has one end fixed to the handle 160 and the other end connected to the trigger 171. After the cutting device has cut the tape, the user releases the trigger 171, and the reset device 177 pushes the trigger 171 to the initial position, thereby resetting the linkage mechanism and the blade.

According to the utility model discloses a hand-held type sticky tape applicator can also be provided with terminal point indicating device. The end point indicating device is capable of indicating the end point position where the cut tape can be applied on the surface of the target product. When the terminal point indicating device points to the terminal point position, a user can press the trigger, so that the cutter is driven to cut the adhesive tape. In this way, the timing of the cutting can be accurately controlled, avoiding waste of cutting the tape too long or failure of the cutting tape too short to be applied to the end position.

The structure and operation of the end-point indicating device will now be described with reference to fig. 9. According to an exemplary embodiment of the present invention, the end point indicating device is an end point indicator 162. The end indicator 162 is a sheet-like "L" shaped sheet of material secured to the support plate 110. The plane of the sheet extends parallel to the axis of the tape application roller. Of course, other shapes of end point indicators are also contemplated, or other forms of end point indicating devices such as laser pointers are contemplated, so long as the user is able to indicate to the user the location of the end point on the surface of the target product at which the tape is to be applied. As shown in fig. 9, when the tape is applied to the surface of the target product using the tape applicator, a line where an extended line of the end point indicator 162 intersects the surface of the target product is denoted by a, and a line where the tape applying roller 130 presses the tape to the target product is denoted by B. The line at which the cutter 174 cuts the tape is indicated by C. The length AB of the tape between lines a and B is equal to the length BC between lines B and C, depending on the structural design of the tape applicator. When the adhesive tape is applied to the target product, a line where an extension line of the end point indicator 162 intersects with the surface of the target product is located at the end point position, and the user presses the trigger 171 to cause the scissors to cut the adhesive tape. Since length AB is equal to length BC, the cut tape is applied to the target product just before the end position. Thereby, an accurate application of the adhesive tape is achieved in a simple and fast manner.

In addition, the hand-held adhesive tape applicator according to the present invention further comprises an additional shearing mechanism 180. Referring to fig. 1 and 10, an additional shearing mechanism 180 is fixedly attached to the support plate 110. The additional shearing mechanism 180 includes a tool holder 181, a tool 182, and a cutter shaft 183. The cutter 182 is coupled to the cutter holder 181 by a cutter shaft 183. The tool 182 can be fixedly connected to the tool holder 181 and can also be rotatably coupled to the tool holder 181. The plane of the cutter 182 of the additional shearing mechanism 180 is parallel to the axis of the tape application roller 130 and is arranged such that: when the tape is applied by the tape application roller 130, it is positioned behind the tape application roller 130 in the advancing direction of the tape application roller 130, that is, above the tape that has been applied to the target product when the tape is applied. When the application of the adhesive tape is completed, the auxiliary roller 131 side is first lifted, and then the adhesive tape application roller 130 is lifted, and the cutter 182 of the additional cutting mechanism is placed at a position of the adhesive tape on the target product to be cut. The tape may be cut by sliding or rolling a cutter over the tape in the direction of line G as shown in fig. 10.

Another feature of the hand-held adhesive tape applicator according to the present invention is that the adhesive tape applying part 100 and the adhesive tape supporting part 200 are detachably coupled together, and thus, they may be in a coupled configuration or in a separated configuration from each other, thereby operating in a separated state or in a coupled state. Fig. 11 shows the adhesive tape applying part 100 and the adhesive tape supporting part 200 in a disassembled state. In the illustrated exemplary embodiment, the tape support portion 200 has a support bracket 210. The first end of the support frame 210 is provided with a support wheel 230. The tape roll 201 is rotatably supported on the support wheel 230. The second end of the supporting bracket 210 can be fixedly connected with the supporting plate 110 by a connection means such as a screw connection, a rivet connection, etc. Other detachable fixed connections are also conceivable. In the detached state, the tape supporting part 200 separated from the tape applying part 100 can be hung on other supports while the tape can still pass through the clamping mechanism 120 to be guided to the tape applying roller 130. In this case, when the adhesive tape is applied, the weight of the hand-held portion of the user can be reduced. Particularly, when the tape is applied for a long time or the tape roll is heavy, the user's physical strength can be saved.

As shown in fig. 12, the adhesive tape applicator 1 according to the present invention further has a lateral positioning mechanism, which in the illustrated embodiment comprises a first lateral positioning element and a second lateral positioning element. The first lateral positioning member includes a first lateral positioning roller 151, a first roller bracket 153, and a first adjusting nut 155. The second lateral positioning member includes a second lateral positioning roller 152, a second roller bracket 154, and a second adjustment nut 156. The first roller holder 153 and the second roller holder 154 are fixed to the support frame 110. The first lateral registration roller 151 is coupled to the first roller bracket 153 by a first adjustment nut 155 and is freely rotatable about its own rotational axis. The distance between the first lateral direction positioning roller 151 and the support plate 110 can be adjusted by loosening the first adjustment nut 155. And after the first lateral registration roller 151 is adjusted to a desired position, the first lateral registration roller 151 can be fixed by screwing the first adjustment nut 155. The second lateral positioning roller 152, the second roller bracket 154 and the second adjustment nut 156 have the same coupling and operation and are not described in detail herein. Of course, it is also possible to include only one lateral positioning element.

The first and second lateral registration rollers 151 and 152 can abut against and roll on the sides of the target product when the tape is applied to the target product. The distance between the lateral positioning roller and the tape application roller 130 can determine the distance E of the applied tape from the side edge of the target product. Because of the two lateral positioning rollers, the lateral positioning of the adhesive tape applicator is more stable, and the laying of the adhesive tape is more accurate. When the lateral registration roller is not used, it can be removed or rotated to a position that does not interfere with the application of the tape. The lateral positioning devices shown are exemplary and other structures or components capable of determining the distance of the applied tape from the edge of the target product are also contemplated.

To present specific embodiments of the tape applicator of the present invention in detail, exemplary configurations, mechanisms, components, and couplings are disclosed above. It will be apparent, however, to one skilled in the art that the specific details set forth above are not necessarily required, that the exemplary configurations, mechanisms, components, and couplings may be embodied in many different forms and that the specific details and exemplary configurations, mechanisms, components, and couplings should not be construed as limiting the scope of the disclosure.
