Description

Technical Field

[0001] The utility model relates to the technical field of stationery production and manufacturing, in particular to a deceleration regulating device for a plastic tape cutting machine. Background Art

[0002] The plastic tape cutting machine is a tool used for cutting plastic tape to a predetermined depth. The plastic tape is folded in half and wrapped around a paper label, and then combined with a notebook to form a notebook with a label. The plastic tape serves to reinforce the label and can effectively prevent the label from being torn. The auxiliary folding crease formed by the plastic tape cutting machine cutting the plastic tape to a predetermined depth is to prevent the plastic tape from rebounding after being folded in half, and to avoid white spots and bubbles caused by rebound of the plastic tape. Therefore, in the process of the plastic tape cutting machine cutting the plastic tape, the rotating shaft at the output end of the plastic tape is driven to rotate by a motor, and the rotating shaft at the input end of the plastic tape is driven to rotate by the output end rotating shaft. Since the diameters of the rolled plastic tape at the input end shaft and the output end shaft are different, the rotation speed of the input end rotating shaft does not match the rotation speed of the output end rotating shaft, which easily causes the plastic tape at the input end to bulge when being led out, and the plastic tape cannot be well attached to the surfaces of various components of the plastic tape cutting machine, thereby reducing the cutting accuracy of the plastic tape by the plastic tape cutting machine.

[0003] It can be seen that how to improve the processing accuracy of plastic belts during operation and cutting has become an urgent problem to be solved. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The utility model is further described in detail below with reference to the accompanying drawings: Example

[0034] See also Figures 1 to 4 The present embodiment provides a deceleration adjustment device for a plastic tape cutting machine 1, wherein the plastic tape cutting machine 1 comprises: a base assembly 10, a transmission component 20, the transmission component 20 is connected to the base assembly 10, and the transmission component 20 rotates and transports the plastic tape 2 through a rotating shaft 30. At the same time, the plastic tape cutting machine 1 also comprises: a cutting platform 40, a bracket body 41, a telescopic member 42 and a cutting blade 43, the bracket body 41 is connected to the base assembly 10, the telescopic member 42 is movably connected to the bracket body 41, the cutting blade 43 is connected to the telescopic member 42, the cutting platform 40 is connected to the base assembly 10, and the telescopic member 42 is adjusted in a direction close to or away from the cutting platform 40, so that the cutting blade 43 penetrates into the plastic tape 2 to a predetermined depth.

[0035] Among them, it should be noted that the object processed by the plastic tape cutting machine 1 in this embodiment is a long strip of plastic tape 2, and the plastic tape 2 is combined with a paper label and applied to a notebook. The plastic tape cutting machine 1 in this embodiment is a processing operation on the plastic tape 2 before application. The plastic tape 2 wrapped in film is fixed to the conveying component 20. Through the rotation of the rotating shaft 30, the pulled out plastic tape 2 is cut by the cutting component and output as a plastic tape 2 that can be folded in half.

[0036] Furthermore, a deceleration adjustment device is provided in this embodiment, including: a base 100, which is connected to the machine base assembly; an adjustment member 200, one end of which is connected to the base 100, and the surface of the rod body of the adjustment member 200 is in contact with the surface of the rotating shaft 30 of the transmission assembly 20, and the other end of the adjustment member 200 naturally droops due to gravity.

[0037] The deceleration regulating device in this embodiment is for decelerating the rotation of the rotating shaft 30 in the transmission component 20, wherein the rotating shaft 30 is passively rotated, one end of the rotating shaft 30 is the input end of the transmission component 20, and the transmission component 20 at the other end is the output end, and the output end is externally connected to a motor, and the rotation of the motor drives the movement of the plastic belt 2, and the rotation of the rotating shaft 30 is passively driven as the plastic belt 2 runs. At the same time, since the diameters of the plastic belt 2 on the shaft bodies at both ends of the transmission component 20 are different, the rotation speed of the rotating shaft 30 at the input end is different. The degree requires passive matching of the rotation speed of the shaft at the output end, so the rotation speed of the rotating shaft 30 at the input end cannot achieve the optimal uniform rotation. In the actual production process, the rotation speed of this side of the rotating shaft 30 is slightly faster than the rotation speed of the shaft at the output end. The speed at which the output end receives the plastic belt 2 is slow, while the speed at which the input end leads out the plastic belt 2 is fast. This will cause the plastic belt 2 to bulge due to the mismatch in the rotation speed during a certain distance when the plastic belt 2 is led out, thereby reducing the cutting accuracy of the plastic belt 2 by the cutting blade 43. Therefore, the deceleration adjustment device in this embodiment is connected with the base assembly 10 through the base 100, and the adjustment member 200 is against the surface of the rotating shaft 30. The adjustment member 200 is a rod structure. Through the weight of the adjustment member 200 and the friction generated by the contact between the adjustment member 200 and the surface of the rotating shaft 30, the direction of the friction force is opposite to the rotation direction of the rotating shaft 30, thereby reducing the rotation speed of the rotating shaft 30 to a certain extent, thereby ensuring that the speed of the plastic belt 2 led out from one end of the rotating shaft 30 matches the speed of the plastic belt 2 received at the output end, thereby reducing the bulge of the lead-out part of the plastic belt 2.

[0038] Furthermore, the base assembly 10 is provided with a mounting portion 11 , the base 100 is connected to the mounting portion 11 , and the base 100 is movable relative to the mounting portion 11 .

[0039] By adjusting the position of the base 100, the contact point between the adjusting member 200 and the rotating shaft 30 can be adjusted to a certain extent. Preferably, the adjusting member 200 is a long rod structure, and the surface of the adjusting member 200 can be provided with different textures in sections. By adjusting the position of the base 100, different positions on the surface of the adjusting member 200 can be made to contact the rotating shaft 30. Different positions have different textures, and surfaces with different textures generate different frictional forces when in contact with the rotating shaft 30. According to actual use needs, rubber or other material items can be sleeved on the surface of the adjusting member 200 to further increase the frictional force.

[0040] The mounting portion 11 is a strip-shaped groove structure, and the base 100 is embedded in the mounting portion 11 . The base 100 can be moved in the strip-shaped groove to adjust the position of the base 100 .

[0041] The part of the base 100 that engages with the groove is a cylindrical screw structure with a threaded surface. The cylindrical screw structure can pass through the back of the base assembly 10. After extending out of the base assembly 10, the base 100 is fixed and limited by the cooperation of the nut and the cylindrical screw. When the position of the base 100 needs to be adjusted, the base 100 can be moved by simply loosening the nut.

[0042] The adjusting member 200 includes: a first adjusting rod 210, which is connected to the base 100; a second adjusting rod 220, which is connected to the first adjusting rod 210, and the second adjusting rod 220 is bent relative to the first adjusting rod 210, and the bending direction of the second adjusting rod 220 is toward the direction of gravity.

[0043] Among them, the adjusting member 200 in this embodiment is composed of a first adjusting rod 210 and a second adjusting rod 220, which is a multi-section adjusting rod. In this embodiment, it is preferably two sections. The multi-section rod body cooperates with the movable base 100 to achieve multi-point contact or single-point contact between the adjusting member 200 and the rotating shaft 30. The number of contact points is different, and the friction force that can be provided is also different, which can be set according to the actual operating conditions of the plastic belt 2.

[0044] Furthermore, the first adjustment rod 210 and the second adjustment rod 220 in this embodiment can be a slightly curved rod structure, which further increases the contact area between the first adjustment rod 210 and the second adjustment rod 220 and the rotating shaft 30, thereby further increasing the magnitude of the friction force that can be provided.

[0045] Furthermore, the first adjustment rod 210 is rotatably connected to the base 100, and the first adjustment rod 210 can be swung and adjusted relative to the base 100 along the direction of gravity; the second adjustment rod 220 is rotatably connected to the first adjustment rod 210, and the second adjustment rod 220 can be swung and adjusted relative to the first adjustment rod 210 along the direction of gravity.

[0046] The first adjusting rod 210 is connected to the base 100 through a certain rotating shaft. Similarly, the second adjusting rod 220 is connected to the first adjusting rod 210 through a certain rotating shaft. Therefore, the adjusting member 200 in this embodiment can provide two-stage bending angle adjustment, and the rotation between the base 100 and the first adjusting rod 210, and the first adjusting rod 210 and the second adjusting rod 220 has a certain rotational damping, which makes it easier for the operator to lift the first adjusting rod 210 or the second adjusting rod 220 at any time, so that the first adjusting rod 210 and the second adjusting rod 220 are suspended relative to the rotating shaft 30, which is convenient for the operator to take the rotating shaft 30 to replace the rolled plastic belt 2.

[0047] The deceleration adjustment device further includes: a counterweight assembly 300 , which is fixedly connected to one end of the adjustment member 200 , and is located at one end of the adjustment member 200 away from the base 100 .

[0048] Specifically, the counterweight assembly 300 is connected to the end of the second adjustment rod 220. The counterweight assembly 300 cooperates with the second adjustment rod 220 to further improve the drooping quality of the second adjustment rod 220, thereby further improving the friction force generated by the contact between the adjustment member 200 and the rotating shaft 30 as needed.

[0049] Preferably, the counterweight assembly 300 includes: a connecting member 310, one end of which is connected to the adjusting member 200; and a counterweight 320, which is detachably connected to the connecting member 310.

[0050] See also Figure 4 The connecting piece 310 is an inverted T-shaped structure. Similarly, the adapted counterweight 320 is also a structure with an inwardly concave T-shaped hollow. The counterweight 320 and the connecting piece 310 are connected in a detachable manner, and the connection is completed by embedding the T-shaped connecting piece 310 into the T-shaped concave of the counterweight 320. There are multiple options for the counterweight 320, and the masses of the multiple counterweights 320 are different. The counterweight 320 to be assembled can be selected according to actual usage requirements. Example

[0051] In this embodiment, the deceleration adjustment device also includes: a limiting belt 400, one end of which is fixedly connected to the telescopic member 42, and the other end of the limiting belt 400 is squeezed and fitted to the plastic belt 2 located on the cutting platform 40, and the limiting belt 400 is located on the top of the plastic belt 2.

[0052] Furthermore, an opening 410 is formed at the end of the limiting belt 400 , and an arc-shaped transition is formed from one end of the limiting belt 400 to the other end of the limiting belt 400 . The cutting blade 43 passes through the opening 410 to cut the plastic belt 2 .

[0053] The telescopic member 42 is a rod structure with threads on the outer surface. A knob 44 is provided on the telescopic member 42 . By rotating the knob 44 , the telescopic member 42 can be moved up and down in the vertical direction, thereby adjusting the feeding depth of the cutting blade 43 .

[0054] The limiting belt 400 is a belt-shaped object with a certain toughness, and in the absence of any external force, the limiting belt 400 is a straight belt-shaped object. In this embodiment, one end of the limiting belt 400 is fixedly connected to the telescopic member 42 by human action, and then the limiting belt 400 is bent to set the other end of the limiting belt 400 with an opening 410 in the middle, see Figure 3The opening 410 is a long strip-shaped opening 410, and the opening 410 passes through the cutting blade 43 along the running direction of the plastic belt 2. The cutting blade 43 cooperates with the component that clamps the cutting blade 43 to fix the limiting belt 400 to a certain extent, and the other end of the limiting belt 400 rests against the top of the plastic belt 2 through its own resilience, thereby reducing the bulging phenomenon of the plastic belt 2 during the cutting process, so as to improve the cutting accuracy of the plastic belt 2 by the cutting blade 43. Example

[0055] In this embodiment, the adjusting member 200 can be set as a soft cloth belt under some specific working conditions. Due to the material characteristics of the cloth belt itself, the adjusting member 200 made of cloth belt material can further increase the fitting area between the adjusting member 200 and the rotating shaft 30 when it is fitted around the rotating shaft 30. The adjusting member 200 made of cloth belt material has an excellent surface texture. The friction force can be further increased through the fitting of the cloth belt and the rotating shaft 30, and the rotation speed of the rotating shaft 30 can be effectively reduced, thereby avoiding the bulge when the plastic belt 2 is led out from the rotating shaft 30.

[0056] Preferably, one end of the adjusting member 200 made of cloth tape in the present embodiment can be wound around the base 100 for fixation, and one end of the adjusting member 200 made of cloth tape can also be directly wound around the limiting roller 3 for fixation.

[0057] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
