Description

Technical Field

[0001] This utility model belongs to the field of blade packaging technology, specifically relating to a packaging machine for pruning machine blades. Background Technology

[0002] Pruning machines are suitable for professional pruning in landscaping applications such as tea plantation trimming, park gardens, and roadside hedges. The machines are equipped with blades for trimming vegetation. After production, the pruning machine blades need to be packaged and transported to prevent collisions and friction with other objects (including other blades) during transport, which could lead to chipping, breakage, or deformation, thus affecting product quality and performance. This also prevents the metal blades from being exposed to moisture and oxidizing, rusting.

[0003] Currently, the packaging of blades usually relies on operators to manually complete the packaging, which is inefficient and cannot meet the needs of packaging large quantities of blades. In addition, manual packaging is labor-intensive, and careless operation can easily cut the operator's hands, posing certain safety hazards. Summary of the Invention

[0004] This utility model provides a packaging machine for pruning machine blades, which solves the problems of low efficiency and low safety of existing manual packaging.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a baling machine for pruning machine blades, comprising:

[0006] An unwinding assembly, used for unwinding packing tape;

[0007] A feeding assembly, comprising a feeding frame, feeding rollers rotatably mounted between and spaced apart from the feeding frame, and a feeding belt wound around the feeding rollers, the feeding belt being used to feed the blades onto the packing material belt;

[0008] The packaging assembly includes a packaging frame, a carrier plate fixed to the top of the packaging frame, and a gathering mechanism disposed on the top of the carrier plate. The gathering mechanism is used to gather the packaging tape unwound by the unwinding assembly.

[0009] Optimally, the unwinding assembly includes an unwinding frame, an unwinding shaft rotatably mounted on one side of the unwinding frame, and at least two sets of limiting mechanisms adjustable along the axial direction of the unwinding shaft.

[0010] Ideally, each set of limiting mechanisms includes a retaining ring sleeved on the unwinding shaft and a retaining rod encircling the outer circumferential surface of the retaining ring.

[0011] Optimally, the feeding assembly further includes a baffle mounted on the top of the feeding rack and disposed opposite to it, a first adjustment groove penetrating the baffle, a fixing hole formed on the top of the feeding rack and cooperating with the first adjustment groove, and a feeding groove formed between the baffles.

[0012] Optimally, the gathering mechanism includes an adjustable plate that is adjustablely mounted on the top of the carrier plate, a vertical plate integrally connected to the top of the adjustable plate, a first inclined portion that is inclinedly opened on the side of the vertical plate near the feeding assembly, and a second inclined portion that is inclinedly opened on the side of the carrier plate near the feeding assembly.

[0013] Optimally, the gathering mechanism further includes an anti-scratch rod fixed to one side of the second inclined portion, a first arc-shaped portion disposed on the first inclined portion, and a second arc-shaped portion disposed on the side of the carrier plate near the feeding assembly.

[0014] Optimally, the gathering mechanism further includes a sliding groove formed on the top of the carrier plate and a second adjusting groove that passes through the adjusting plate and cooperates with the sliding groove, the second adjusting groove being perpendicular to the sliding groove.

[0015] Optimally, the feeding assembly further includes a tensioning shaft installed between the feeding frames, a rolling sleeve rotatably sleeved on the tensioning shaft, and a limiting sleeve spaced on the rolling sleeve.

[0030] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0031] like Figure 1 , 2The diagram shows the structure of the packaging machine for pruning machine blades according to this utility model. The packaging machine consists of an unwinding assembly 1, a feeding assembly 2, and a packaging assembly 3. These three components are arranged sequentially within the packaging workshop. The unwinding assembly 1 unwinds the packaging tape, while the feeding assembly 2 conveys the pruning machine blades to be packaged (pruning machine blades can be packaged individually or in multiple overlapping bundles, depending on customer needs). The packaging assembly 3 serves two purposes: firstly, it receives the packaging tape unwound by the unwinding assembly 1 and simultaneously gathers it; secondly, it receives the pruning machine blades conveyed by the feeding assembly 2 (i.e., feeds the pruning machine blades into the gathered packaging tape). The gathered packaging tape is then further sealed and cut (sealed using a heat sealer and cut using a cutting machine).

[0032] like Figure 3 The diagram shows the structure of the unwinding assembly 1. The unwinding assembly 1 is used to unwind the packaging tape. The unwinding assembly 1 includes an unwinding plate 101, a bearing seat 102, an unwinding shaft 103, a retaining ring 104, and a retaining rod 105. The unwinding plate 101 is a rectangular metal plate, which is fixed to a metal support plate on the workshop floor by welding and is vertically arranged. The unwinding shaft 103 is rotatably installed on the top of the unwinding plate 101 (specifically, the top of the unwinding plate 101 has a through hole for the unwinding shaft 103 to pass through. There are two bearing seats 102, which are fixed to both sides of the unwinding plate 101 by screws. Bearings are installed in the bearing seats 102, and the bearings are coaxially arranged with the through hole on the unwinding plate 101).

[0033] The unwinding shaft 103 passes through the bearing in the bearing housing 102 with an interference fit. Under the action of the bearing, the unwinding shaft 103 can rotate normally, thereby realizing the unwinding of the packing strip (by installing bearing housings 102 on both sides of the unwinding plate 101, the stability of the rotation of the unwinding shaft 103 is improved).

[0034] At least two retaining rings 104 are fitted onto the unwinding shaft 103 with an interference fit and spaced apart. (The retaining rings 104 are rubber rings, which reduce the load on the unwinding shaft 103 and facilitate easy removal for replacing the packing tape.) During actual installation, first remove the retaining ring 104 on the side furthest from the unwinding plate 101. Wind the packing tape into a disc and place it onto the unwinding shaft 103. The disc-shaped packing tape abuts against the retaining ring 104 on the side closest to the unwinding plate 101. Finally, place the other retaining ring 104 onto the unwinding shaft 103 until it abuts against the packing tape. (The two retaining rings 104 limit the center of the packing tape, preventing it from swinging during unwinding and affecting the blade sealing. The distance between the two retaining rings 104 can be adjusted according to the width of the packing tape, improving the equipment's versatility.)

[0035] The locking rod 105 is integrated on the outer circumference of the locking ring 104 and close to the inner side of the locking ring 104 (there are at least three locking rods 105). By setting the locking rod 105, the coiled packing material is limited to prevent the packing material from swinging when unwinding.

[0036] like Figure 4-6 The diagram shows the structure of the feeding assembly 2. The feeding assembly 2 is used to transport the pruning machine blades to be packaged (the pruning machine blades can be transported and packaged individually or stacked before being transported and packaged). The feeding assembly 2 includes a feeding plate 201, a feeding roller 202, a feeding motor 203, a feeding belt 204, a baffle 205, a first adjusting groove 206, a fixing hole 207, a first tensioning shaft 208, a first rolling sleeve 209, a first limiting sleeve 210, a second tensioning shaft 211, a second rolling sleeve 212, a second limiting sleeve 213, a lifting shaft 214, and a lifting sleeve 215. The feeding plate 201 is a rectangular metal plate, which is fixed to the metal support plate on the workshop floor by welding and is set vertically. The feeding rollers 202 are rotatably installed between the feeding plates 201 and are spaced apart. (Specifically, the top of the feeding plate 201 has a through hole, and a bearing is installed in the through hole. The two ends of the feeding rollers 202 are respectively installed in the bearings. Under the action of the bearings, the feeding rollers 202 can rotate normally, thereby driving the feeding belt 204 above to rotate to feed the pruning machine blades to the packaging assembly 3.)

[0037] The feeding belt 204 is wound around the feeding roller 202 to transport the blades to be packaged. The housing of the feeding motor 203 is fixed to the outside of the feeding plate 201 by screws. The motor shaft of the feeding motor 203 is connected to the feeding roller 202 through a coupling. The feeding motor 203 drives the feeding roller 202 to rotate, which in turn drives the feeding belt 204 to rotate, so as to transport the blades to be packaged.

[0038] Two baffles 205 are installed opposite each other on the top of the feeding plate 201 to limit and guide the conveyed blades, ensuring that the blades can smoothly enter the packing material belt of the packing assembly 3 and preventing the blades from deviating to the sides and failing to accurately enter the packing assembly. The first adjusting groove 206 extends vertically through the baffle 205. The first adjusting groove 206 is a rounded rectangle and is parallel to the width direction of the feeding belt 204. The fixing hole 207 is opened on the top of the feeding plate 201 and mates with the first adjusting groove 206 (the inner wall of the fixing hole 207 is provided with internal threads. In actual installation, the fastening bolt is passed through the first adjusting groove 206 and fixed in the fixing hole 207, thereby installing the baffle 205 on the top of the feeding plate 201).

[0039] By opening a first adjustment groove 206 on the baffle 205, the position of the baffle 205 can be adjusted appropriately according to the width of the conveyed blade, thereby adjusting the distance between two adjacent baffles 205 and improving versatility (the pruning machine blade to be packaged is placed on the feeding belt 204 and located in the feeding groove between the two baffles 205, wherein the thickness of a single pruning machine blade is greater than the distance between the baffle 205 and the feeding belt 204 to prevent the pruning machine blade from deviating to both sides).

[0040] The two ends of the first tensioning shaft 208 are fixed horizontally between the feeding plates 201 by screws. The first rolling sleeve 209 is rotatably mounted on the first tensioning shaft 208 (specifically, a bearing is installed between the first rolling sleeve 209 and the first tensioning shaft 208, ensuring that the first rolling sleeve 209 can rotate normally). The first limiting sleeve 210 is fitted onto the first rolling sleeve 209 with an interference fit and is spaced apart. The first limiting sleeve 210 limits the unwinding of the packing material to prevent the material from tilting or swinging left and right (the first limiting sleeve 210 is a rubber sleeve to reduce the load on the first tensioning shaft 208. The spacing between the two first limiting sleeves 210 can be adjusted to meet the tensioning and unwinding of packing materials of different widths).

[0041] The two ends of the second tensioning shaft 211 are fixed horizontally between the feeding plates 201 by screws, and the second tensioning shaft 211 is located below the first tensioning shaft 208. The second rolling sleeve 212 is rotatably mounted on the second tensioning shaft 211 (specifically, a bearing is installed between the second rolling sleeve 212 and the second tensioning shaft 211, ensuring that the second rolling sleeve 212 can rotate normally under the action of the bearing). The second limiting sleeve 213 is fitted onto the second rolling sleeve 212 by interference fit and is spaced apart. The second limiting sleeve 213 limits the unwinding of the packing material and prevents the material from tilting or swinging left and right (the second limiting sleeve 213 is a rubber sleeve to reduce the load on the second tensioning shaft 211. By adjusting the distance between the two second limiting sleeves 213, the tensioning and unwinding of packing materials of different widths can be met).

[0042] By setting the first tensioning shaft 208 and the second tensioning shaft 211, the unwound packing strip is tensioned to prevent it from becoming loose and tangled. At the same time, the tensioning of the first tensioning shaft 208 and the second tensioning shaft 211 can also prevent the sides of the packing strip from warping, curling, and being squeezed together.

[0043] The two ends of the lifting shaft 214 are fixed between the feeding plates 201 by screws and are set horizontally. The lifting sleeve 215 is rotated and mounted on the lifting shaft 214 (specifically, a bearing is installed between the lifting sleeve 215 and the lifting shaft 214. Under the action of the bearing, the lifting sleeve 215 can rotate normally, thereby conveying the unwound packing material).

[0044] like Figure 2 The diagram shown is a simplified illustration of the unwinding of the packing tape. After unwinding, the packing tape passes over the first rolling sleeve 209 from top to bottom, then passes over the second rolling sleeve 212 from bottom to top, and finally passes over the lifting sleeve 215 to be delivered to the packing assembly 3. The lifting sleeve 215 is set to lift the packing tape and prevent the packing tape from hanging downwards and rubbing against the ground.

[0045] like Figure 7 , 8 The diagram shows the structure of the packing assembly 3. The packing assembly 3 serves two purposes: firstly, it receives the packing tape unwound by the unwinding assembly 1 and simultaneously gathers the packing tape; secondly, it receives the pruning machine blades conveyed by the feeding assembly 2. The packing assembly 3 includes a packing plate 301, a carrier plate 302, a sliding groove 303, an adjusting plate 304, a second adjusting groove 305, a vertical plate 306, a reinforcing plate 307, a first inclined portion 308, a second inclined portion 309, an anti-scratch rod 310, a first arc-shaped portion 311, a second arc-shaped portion 312, a third tensioning shaft 313, a third rolling sleeve 314, and a third limiting sleeve 315. The packing plate 301 is vertically fixed to a metal support plate on the workshop floor by welding, and the carrier plate 302 is fixed to the top of the packing plate 301 by welding or screw fastening.

[0046] The sliding groove 303 passes through the carrier plate 302 and is perpendicular to the conveying direction of the blade. The sliding groove 303 is in the shape of a rounded rectangle, which facilitates the adjustment of the distance between the two adjusting plates 304, thereby meeting the needs of gathering packing materials of different widths.

[0047] The second adjustment groove 305 passes through the adjustment plate 304 and is perpendicular to the sliding groove 303. The second adjustment groove 305 is a rounded rectangle. The fastening bolt passes through the second adjustment groove 305 and the sliding groove 303. At the other end, a fastening nut is used to fix the adjustment plate 304 and the carrier plate 302. (By opening the second adjustment groove 305 on the adjustment plate 304, the installation is more flexible, the processing difficulty is reduced, and the situation of hole misalignment due to processing error cannot be fixed is avoided.)

[0048] The vertical plate 306 is fixed to the inside of the adjusting plate 304 by welding and is perpendicular to the adjusting plate 304. The reinforcing plate 307 is welded to the right angle formed by the adjusting plate 304 and the vertical plate 306 to improve the structural strength of the vertical plate 306 and prevent the vertical plate 306 from bending inward when the packing material is gathered.

[0049] The first inclined portion 308 is inclinedly disposed on the side of the vertical plate 306 near the feeding assembly 2, and the second inclined portion 309 is inclinedly disposed on the side of the carrier plate 302 near the feeding assembly 2, as shown below. Figure 8As shown, the upward-facing packing tape passes through the second inclined section 309 and the first inclined section 308, thereby folding the two sides of the packing tape inward (that is, dividing the packing tape into three parts: the bottom receiving section and the two side covers; the blades conveyed by the feeding assembly 2 are fed to the bottom receiving section; the two side covers are folded inward above the blades; and finally, the heat sealing machine heat seals the two side covers together, thereby completing the packaging of the packing tape and the blades).

[0050] The first arc-shaped part 311 is disposed on the first inclined part 308, the second arc-shaped part 312 is disposed on the side of the carrier plate 302 near the feeding assembly 2, and the anti-scratch rod 310 is fixed on the second inclined part 309 by welding to prevent the sharp corner part from scratching the packing strip when the material strip is pulled and gathered.

[0051] The third tensioning shaft 313 is fixed horizontally between the packing plates 301 by screws. The third rolling sleeve 314 is mounted on the third tensioning shaft 313 by bearing rotation. The third limiting sleeve 315 is mounted on the third rolling sleeve 314 by interference fit and is spaced apart to limit the packing material conveyed here (the third limiting sleeve 315 is a rubber sleeve to reduce the load on the third tensioning shaft 313. The spacing between the two third limiting sleeves 315 can be adjusted to meet the limiting of packing material of different widths).

[0052] The packaging principle of the pruning machine blade packaging machine of this utility model is as follows:

[0053] The unwinding assembly unwinds the packing tape, the feeding assembly conveys the pruning machine blades to be packed, the packing assembly rewinds the tape while receiving the blades from the feeding assembly, and finally the packing assembly gathers the tape together to complete the packaging of the blades.

[0054] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
