Description

Technical Field

[0001] The utility model relates to the field of bag body manufacturing equipment, in particular to a vertical strip built-in device for the bag body of a bag making machine. Background Art

[0002] The strip of a traditional bag making machine hangs outside the bag body. If it needs to be built in, manual assistance is generally required. The release trajectory of the strip is single, and problems such as strip deviation and winding are likely to occur. Moreover, even if it can be completed by equipment, a complex robotic arm is required, and processes such as bag opening, strip guiding, and bag mouth closing need to be performed step by step, resulting in an extended cycle time, leading to either a waste of human resources or high equipment costs and complex operations. Therefore, there is an urgent need for a strip built-in device with a simple structure and good integration to solve the problem of putting the handle into the bag body, making it convenient for transportation and more aesthetically pleasing. Summary of the Utility Model

[0003] The utility model aims at the deficiencies in the prior art and provides a vertical strip built-in device for the bag body of a bag making machine.

[0004] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0005] A vertical strip built-in device for the bag body of a bag making machine includes a bag body conveying device, a bag mouth opening device, and a strip built-in device. The bag body conveying device is located below the bag body and conveys the bag body in an upright state. The bag mouth opening device is provided with opening components that can move relatively on both sides of the bag body, and the opening components are connected to an opening power source that drives them to make closing / opening movements.

[0006] The strip built-in device includes strip moving components arranged on both sides. The strip moving components are connected to a power mechanism that drives their movement. The power mechanism includes a lifting power source that drives the strip moving components to move up and down. The strip moving components have a first stroke of moving the strip upward above the opening components. After the opening components open to open the bag mouth, relative movement occurs between the strip moving components and the strip, causing the strip to enter the bag body.

[0007] Preferably, the relative movement between the strip moving components and the strip is generated by the strip moving components clamping inward, retracting outward, or pushing upward through their own movement to make the strip fall into the bag body, or other components moving the strip by pushing, blowing, or clamping.

[0008] The relative movement between the strip moving component and the strip is generated by the second stroke of the strip moving component, wherein the strip moving component clamps or holds the strip, and the second stroke includes at least one of upward movement, inward movement, or outward movement, and when the strip moving component is in the second stroke, the bag opening component opens to keep the bag opening in the bag opening state. If it is upward, the bag opening can fall into the bag opening, and if there is an inward movement, it is more convenient for the strip moving component to detach from the belt handle when it retreats outward, and if it is outward, it will actively detach from the belt handle, and the belt handle will naturally hang down into the bag body.

[0009] Preferably, when the first stroke of the belt-shifting strip component ends, the belt-shifting strip component is located above the bag body.

[0010] Preferably, it also includes a fixed plate, on which a transverse guide rail is fixedly installed, on which a slider connected to a bag opening power source is slidably arranged, the bag opening component is connected to the slider, and the fixed plate is provided with a channel for the bag body to pass vertically.

[0011] Preferably, the power mechanism further comprises a belt handle power source for driving the belt strip components on both sides to move toward or away from each other.

[0012] Preferably, the belt strip shifting member moves inwardly to below the belt handle before the first stroke.

[0013] As a preference, the power mechanism comprises a sliding seat connected to the lifting power source, and the power source is arranged on the sliding seat. By adjusting the lifting stroke and the lateral displacement, more bag specifications can be adapted.

[0014] Preferably, the fixing plate is provided with a passage for the bag body to pass vertically.

[0015] Preferably, the belt-shifting strip component is made of a flexible material that can be deformed in the vertical direction. The flexible belt-shifting strip component will not scratch the surface of the bag body, and for the belt handle that is close to the bag surface, it can fully contact the belt handle and move the belt handle upward, so that the yield of the device is higher.

[0016] Preferably, the strip moving component is a brush. The flexible contact of the brush avoids damage to the surface of the bag body and the strip, and fully protects the surface of the bag body and the strip, especially for the hot stamping / laminated material.

[0017] Preferably, the bag opening component is a suction nozzle connected to a negative pressure source. The suction nozzle type bag opening component combines negative pressure adsorption to avoid bag mouth tearing.

[0018] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0019] The whole process of belt positioning, lifting and releasing is automated through the combined control of the lifting and lateral movement of the belt-shifting components. The inherent thinking of traditional components that complete all actions in a single movement is broken through. Through the coordinated movement of the bag opening device and the belt internal device, the belt can be accurately delivered, avoiding belt jams and achieving high work efficiency.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1

[0025] A vertical strip built-in device for bag body of bag making machine, such as Figure 1-2 As shown, it comprises a bag conveying device 1, a bag opening device 2 and a strip inserting device 3. The bag conveying device 1 is located below the bag to convey the bag in a vertical state; the bag opening device 2 is provided with bag opening parts 21 on both sides of the bag that can move relatively, and the bag opening parts 21 are connected to a bag opening power source 22 that drives it to close / open; the strip inserting device 3 comprises a strip moving part 31 provided on both sides, and the strip moving part 31 is connected to a power mechanism 32 that drives it to move, and the power mechanism 32 comprises a lifting power source that drives the strip moving part 31 to move up and down; the strip moving part 31 has a first stroke that moves the strip upward to above the bag opening part 21, and after the bag opening part 21 is opened to open the bag mouth, a relative movement is generated between the strip moving part 31 and the strip, so that the strip enters the bag body. The relative movement between the strip moving component 31 and the strip is caused by the strip moving component 31 clamping inwards or retreating outwards or pushing up to make the strip fall into the bag body through its own movement, or by other components moving the strip by pushing, blowing or clamping.

[0026] The relative movement between the belt-moving strip component and the belt is generated by the second stroke of the belt-moving strip component 31, wherein the belt-moving strip component 31 clamps or holds the belt, and the second stroke includes at least one of upward movement, inward movement or outward movement, and when the belt-moving strip component 31 is in the second stroke, the bag opening component 21 opens to keep the bag opening in an open state.

[0027] It also includes a fixed plate 4, on which a transverse guide rail 41 is fixedly installed. A slider 42 connected to the bag opening power source 22 is slidably arranged on the transverse guide rail 41. The bag opening component 21 is connected to the slider 42. The fixed plate 4 is provided with a channel for the bag body to pass vertically.

[0028] The power mechanism 32 also includes a belt handle power source 33 for driving the belt strip components 31 on both sides to move toward or away from each other.

[0029] The belt strip shifting member 31 moves inwardly to below the belt handle before the first stroke.

[0030] The belt strip component 31 can move upward / inward / obliquely upward in the second stroke. If it moves upward, the bag opening can be dropped into the bag opening. Preferably, the belt strip component 31 moves upward to a state of being separated from the belt handle. If it moves inward, it is more convenient for the belt strip component 31 to be separated from the belt handle when it is withdrawn outward.

[0031] When the first stroke of the tape strip component 31 ends, the tape strip component 31 is located above the bag body.

[0032] It also includes a fixed plate 4 , on which a transverse guide rail 41 is fixedly mounted, on which a slider 42 connected to a bag opening power source 22 is slidably arranged, and the bag opening component 21 is connected to the slider 42 .

[0033] The power mechanism 32 also includes a belt handle power source 33 for driving the belt strip components 31 on both sides to move toward or away from each other.

[0034] The power mechanism 32 includes a sliding seat 34 which is transmission-connected to the lifting power source, and the power source 33 is arranged on the sliding seat 34 .

[0035] The fixing plate 4 is provided with a passage for the bag body to pass vertically.

[0036] When the bag opening power source 22 drives the bag opening component 21 to open the bag, the bag opening components 21 on both sides first move inwardly toward each other and then move outwardly to open.

[0037] The belt moving strip component 31 can be a rigid component in the shape of a plate or a rod. The belt moving strip component 31 can also be made of a flexible material that can deform in the vertical direction. As one example, the belt moving strip component 31 can be a brush. This flexible material can prevent the belt moving strip component 31 from scratching the surface of the bag body. For the handle attached to the bag surface, it can fully contact the handle and move the handle upward.

[0038] The bag opening component 21 can be a component that adheres to the bag body, or can be a suction nozzle connected to a negative pressure source or other means commonly used by those skilled in the art to open the bag.

[0039] Working principle:

[0040] Step 1: First lift of the belt

[0041] After the externally placed paper bag enters the working station, the two belt moving strip components 31 rise to the end of the first stroke under the action of the lifting power source; the belt moving strip components 31 are set at a relatively low position and can first move inward to the position below the handle, approach or contact the bag body, or slightly retract the side of the bag body inward and then move upward. If the belt moving strip components 31 are set at a relatively high position, during the conveying of the bag body, the handle can directly hang above the belt moving strip components 31. At this time, the belt moving strip components 31 can move inward and then upward or directly move upward.

[0042] Step 2: Opening of the bag mouth

[0043] The bag opening component 21 is activated to open the bag mouth. Optionally, the bag opening component 21 is a suction nozzle, and the negative pressure is activated. When the bag opening component 21 is driven by the bag opening power source 22 to open the bag, the two bag opening components 21 first move inward and close towards each other and then move outward and open. This is used to better adsorb and open the bag body.

[0044] Step 3: Release and internal placement of the belt, including the selection of the following implementation methods

[0045] a) Only rising mode: The belt moving strip component 31 continues to rise until it separates from the belt and then releases it;

[0046] b) Composite movement mode: The belt moving strip component 31 moves obliquely upward or obliquely downward, and uses the inner cavity space of the bag mouth to guide the belt to slide in;

[0047] c) Outer movement or inner movement mode: When the belt moving strip component 31 is higher than the bag mouth at the end of the first stroke, it moves inward at this time, uses the inner cavity space of the bag mouth to guide the belt to slide in, and then the belt moving strip component 31 moves outward and separates from the bag strip, or after the bag mouth is opened, the belt moving strip component 31 moves outward, so that the belt freely hangs down and falls into the bag body;

[0048] d) Other components, such as a blowing device, a pushing device, a clamping jaw, etc., drive the belt to separate the handle from the belt moving strip component 31 by pushing, blowing or clamping and fall into the bag body.

[0049] After the release is completed, the bag opening component 21 is closed by negative pressure (if any) and retreats outward, and the belt moving component 31 is reset by the reaction action of the second stroke and the first stroke.

[0050] Step 4: Bag output

[0051] The bag conveying device 1 starts and continues to convey forward. The bag conveying device can realize conveying by means of conveying belt clamping on both sides, clamping or adsorption conveying by adsorption of adsorption parts, etc. The power source is a cylinder, a motor, a motor with a synchronous wheel belt, a screw rod, etc., which are conventionally set by people in this field and will not be described in detail here.
